Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
   The present application claims priority to and the benefit of U.S. Provisional Patent Application Ser. No. 60/371,486, entitled UTILITY TABLE WITH BLOW-MOLDED TABLE TOP, which was filed on Apr. 9, 2002, and is hereby incorporated by reference in its entirety. 

   BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention is generally related to tables and, in particular, to tables with blow-molded plastic table tops. 
   2. Description of Related Art 
   Many different types of tables are well known and used for a variety of different purposes. For example, conventional tables may include legs that are pivotally attached to the table top and the legs may be movable between a use position in which the legs extend outwardly from the table top and a storage position in which the legs are folded against the table top. Large, portable tables with folding legs are often referred to as “banquet tables” and these tables are often used in assembly halls, banquet halls, convention centers, hotels, schools, churches, and other locations where large groups of people meet. Because the tables are portable, the tables can be positioned in an assortment of different configurations and used in a variety of settings. When the tables are no longer needed, the tables can be moved or stored. 
   Banquet tables are often used by various organizations and groups because they allow effective and efficient use of space. For example, banquet tables may be used in large multi-purpose areas such as school gymnasiums, meeting halls and hotel conference rooms to allow groups of people to meet. After the meetings are completed, the tables can be folded into a storage position and stowed in a relatively small space. This allows the gymnasiums, meeting halls and conference rooms to be used for other purposes. Thus, banquet tables allow groups and organizations to efficiently use a particular space. 
   Conventional banquet tables with legs that are foldable between a use position and a storage position may also be used in a variety of other locations. For example, these known tables may provide immediate table space and/or workspace in a house, apartment, garage, tool shed, and the like. The foldable legs allow the tables to be conveniently set up, taken down, stored and transported whenever and wherever the user chooses. 
   It is known to construct conventional banquet tables from relatively heavy materials such as wood or metal, which makes the tables heavy and difficult to move. In particular, the table tops of conventional banquet tables are often made from fiber board, particle board, or plywood, and these known table tops may include a plastic or Formica-type surface laminated onto the upper surface of the table top to create a working surface. Disadvantageously, many of these conventional banquet tables are not very strong and are unable to support a desired amount of weight. In order to increase the strength of these tables, thicker and heavier table tops are often used. Unfortunately, the thicker and heavier table tops further increase the weight of the tables. As a result, many conventional banquet tables with wooden table tops are undesirably heavy, and two or more people are often required to move the tables. 
   In order to prevent the middle portion of conventional banquet tables from sagging, it is known to attach a metal frame to the bottom surface of the wooden table top. These known metal frames often included two side rails that extended along the longitudinal length of the table top and the metal frames are frequently attached to the table top by a plurality of screws. Disadvantageously, the structural integrity of the table top may be decreased by the holes created by the plurality of screws, and this may allow the table to collapse and fail. In addition, because the screws are typically individually attached to the table top, that may significantly increase the amount of the time required to construct the table. 
   Conventional banquet tables are often six or eight feet in length and two or three feet in width. Thus, banquet tables are often difficult to move because of their large size and inherent bulkiness. In addition, as discussed above, these conventional banquet tables are often heavy. Accordingly, if these unwieldy and heavy conventional tables are inadvertently dropped, tipped over, or mishandled while moving or using the tables, then injury could result. 
   It is known to construct banquet tables from plastic or other lightweight materials in an attempt to decrease the weight of the tables. Many of these lighter-weight tables, however, lack the strength and sturdiness of the heavier-weight tables. Thus, many lighter-weight tables require complex support mechanisms and one or more support braces to increase the strength and sturdiness of the table, which undesirably increases the weight and complexity of the tables. 
   Conventional banquet tables generally include legs that are attached to the table tops by a number of mechanical fasteners such as screws or bolts, whether the table tops are constructed from wood, plastic or metal. Disadvantageously, attaching the legs to the table tops by screws or bolts creates a number of holes in the table tops. As discussed above, these holes may decrease the structural integrity of the table top and may create undesirable stress concentrations in the table top. The holes may also create weakness or failure points that allow the table to give way and collapse. It is also known to bond the table legs to the table top by adhesives such as glue, epoxy resins or other suitable types of bonding agents. The bonding of the legs to the table top, however, may decrease the structural integrity of the table top. Significantly, if the mechanical fasteners or adhesive connection of the legs to the table top fails, then the table may collapse. These conventional tables may be difficult to fix or repair, especially if the leg attachment portion of the table top is damaged or pulled away from the remaining portion of the table top. 
   The use of mechanical fasteners to attach the legs to the table top undesirably increases the number of parts required to construct the table, which may increase the time required to assemble the table. In addition, many conventional tables required the legs to be positioned against the underside of the table top and then attached to the table top by the mechanical fasteners or glue. This increases the difficulty of the manufacturing process because the legs and table top must first be held in the desired positions and then the legs must be fastened to the table top. In particular, if mechanical fasteners are used to attach the legs to the table top, mating surfaces such as holes in the legs and corresponding threaded openings in the table top must be carefully aligned before the legs can be attached to the table top. Accordingly, many conventional tables require one or more persons to hold the legs and table top in the desired locations, and another person to fasten the legs to the table top. This process is undesirably time consuming and labor intensive. Alternatively, a single person may be used to attach the legs to the table top, but this process is difficult to perform rapidly and without any errors. 
   It is also known to use complex attachment mechanisms to facilitate attachment of the legs to the table tops. Disadvantageously, these complex attachment mechanisms are generally heavier, more difficult to install, and more expensive. In addition, these complex attachment mechanisms are often more difficult to use than conventional mechanical fasteners or adhesives. 
   These disadvantages are often compounded because conventional tables with folding legs typically require separate and distinct attachment mechanisms for attaching each leg or a pair of legs to the table top. That is, because most conventional banquet tables include a leg or a pair of legs attached to each end of the table, a number of holes or attachment points are required to attach the legs to the table top. Accordingly, many conventional tables have two or four separate points of attachment in order to attach the table legs to the table top. Thus, conventional banquet tables often include a plurality of holes in each end of the table top, and these holes may undesirably allow the table to fail. 
   BRIEF SUMMARY OF THE INVENTION 
   A need therefore exists for a table that eliminates the above-described disadvantages and problems. 
   One aspect of the invention is a table including a table top and legs that are movable between a first position in which the legs extend away from the table top to allow the table to be used and a second position in which the legs are positioned near the table top for storage. Advantageously, the table top and legs create a strong, sturdy and secure table that can be used to support a wide variety of objects and the table can be used for many different purposes. 
   Another aspect is the table top is preferably constructed from blow-molded plastic to allow a lightweight table to be constructed. Significantly, if the table top is constructed from blow-molded plastic, it can easily be formed into any desired configuration, shape, size and design depending, for example, upon the intended use and/or configuration of the table. The blow-molded table top is also generally weather resistant and temperature insensitive, which allows the table to be used in a wide variety of locations and environments. In addition, the blow-molded table top is durable, long-lasting, and it generally does not corrode, rust or otherwise deteriorate over time. Further, because the blow-molded table top is relatively strong, it can be used to support a relatively large amount of weight. Significantly, the blow-molded table top may form a structural member of the table, or the table top may be supported by a frame. 
   Advantageously, the blow-molded plastic table top is relatively strong because it includes two or more opposing walls or surfaces that are separated by a given distance. The opposing walls help create a high-strength, rigid table top. In addition, because the interior portion of the table top is generally hollow, that creates a lightweight table top. Thus, the blow-molded table top is both lightweight and strong. 
   Still another aspect of the table is the table top may include one or more depressions, “tack-offs” or “kiss-offs.” The depressions, which extend from one surface towards another surface, are desirably sized and configured to increase the strength and/or rigidity of the table top. Preferably, the depressions extend from one surface and contact or engage an opposing surface, but the depressions do not have to contact or engage another surface. The depressions are desirably formed in the bottom surface of the table top so that the depressions are generally not visible. The depressions, however, may be formed in the top surface and/or any other suitable portions of the table top. For example, one or more depressions may be formed in the top surface of the table top and one or more depressions may be formed in the bottom surface of the table top, and these opposing depressions may be generally aligned. At least a portion of these opposing depressions may contact or engage each other, but the opposing depressions do not have to touch or engage. 
   Significantly, the blow-molded table top can be quickly and easily constructed. Advantageously, the blow-molding process allows the opposing walls, depressions and other desired features to be quickly and easily formed in the table top. In addition, the blow-molded table top can be constructed as an integral, one-piece structure to help create a strong and rigid table top, but the table top could also be constructed from two or more pieces that are interconnected. 
   A further aspect of the table is the table top can be constructed with thin outer walls that decrease the amount of plastic required to construct the table top. As discussed above, the opposing walls and depressions allow a strong and sturdy table top to be constructed. These and other features also allow the table top to be constructed with relatively thin outer walls, which reduces the amount of plastic required to construct the table top. This may save manufacturing costs and reduce the amount of resources required to construct the table top. The thin outer walls may also allow the table top to be cooled more quickly during the manufacturing process, which may allow the table tops to be manufactured more quickly and efficiently. 
   Additionally, because the table top may be constructed from blow-molded plastic with thin outer walls, this allows a table with reduced weight to be constructed. Significantly, the lightweight table can be easily transported, which decreases shipping costs. Additionally, the consumer may appreciate the reduced weight because they can much more easily move and/or assemble the table. 
   Another aspect of the table is the blow-molded table top may include one or more features that are integrally formed in the table top as part of a unitary, one-piece structure. Advantageously, this may reduce the number of steps required in the manufacturing process, which may reduce the overall cost of the table. For example, the depressions may be integrally formed in the table top during the manufacturing process. In addition, one or more mounting portions may be integrally formed in the table top to allow the frame and/or legs to be attached to the table top. The mounting portions may also allow the frame and/or legs to be attached to the table top without the use of mechanical fasteners such as bolts or screws. 
   Yet another aspect of the table is the one or more depressions formed in the table top may be located in a predetermined pattern to increase the strength of the table top and/or decrease the amount of plastic used to construct the table top. Advantageously, if the depressions are placed near each other, then the table top may be constructed with thinner outer surfaces or walls and the strength of the table top may be increased. Desirably, the locations of the depressions do not vary significantly even when other features are integrally formed in the table top. Thus, for example, the depressions are preferably positioned in close proximity and in the same general pattern even around features such as attachment points, edges and other features of the table top. In addition, one or more depressions may be formed within the various features to maintain the generally consistent pattern of depressions. Significantly, the generally uniform pattern of depressions may allow a table top with homogeneous characteristics to be constructed. 
   A further aspect of the table is the legs can preferably be moved into a storage position to allow the table to be more easily transported or shipped. Desirably, the legs are at least partially disposed within recesses or channels to allow the height of the table in the storage position to be decreased. This may also allow the tables to be more easily stacked, shipped and transported. The legs may also have an oval or other non-circular configuration to further decrease the height of the table in the storage position. 
   Another aspect is the table may be easily assembled and/or disassembled because it does not include any heavy or complex mechanisms to attach the legs to the table top. In contrast, the table preferably includes a frame that can be attached to the table top by a snap, friction or interference fit. Specifically, the frame preferably includes two elongated side rails that are connected to frame mounting portions that are integrally formed in the table top. Significantly, no bolts, screws or other mechanical fasteners are required to attach the frame to the table top, but fasteners may be used if desired. Because mechanical fasteners are not required to attach the frame to the table top, fewer parts are required to assemble the table and no decrease in the structural integrity or strength of the table is created. 
   Still another aspect is the table can be manufactured quickly and easily. In particular, because the frame can be connected to the table top by a snap, friction or interference fit, no fasteners are required to attach the frame to the table top. This may allow the table to be assembled with less time than conventional tables. In addition, because the frame may be simply and easily connected to the table top, fewer workers may be required to assemble the table. Further, the straight forward design and attachment of the frame to the table top may allow the table to be shipped either assembled or unassembled, and it may allow retailers or consumers to assemble the table if desired. 
   A further aspect of the table is the legs may be attached to the frame. In particular, the side rails of the frame may include openings that are sized and configured to receive a cross member that allows the legs to pivot between a use position and a storage position relative to the table top. The openings preferably have a non-circular configuration and the cross member also has a non-circular cross-sectional configuration. In particular, the openings and the cross member may have oval, elliptical, oblong or egg-shaped. configurations. The openings and cross member are preferably configured such that when the legs are positioned in the folded or stored position, the cross member is relatively loosely held within the openings in the frame. On the other hand, when the legs are in the extended or use position, the cross member is held tightly within the openings in the frame. 
   Another aspect of the table is the legs may be held in the folded or storage position by a retaining member or clip. The clip is preferably connected to the table top by a clip receiving portion that is integrally formed in the underside of the table top. The clip is preferably held within the clip receiving portion by a snap, friction or interference fit. 
   Still another aspect of the table is the legs can be held in the upright or extended position by a support brace. The support brace preferably includes a first end that is connected to the leg and a second end that is connected to a retaining member or bracket. The support brace is preferably connected to the leg and the bracket without the use of mechanical fasteners such as screws or rivets. 
   A further aspect of the invention is the support brace may include a locking mechanism that secures the support brace and the legs in an extended position. The locking mechanism preferably secures the legs in the extended position regardless of the position or orientation of the table. Thus, the legs will not move from the extended position to the collapsed position even if the table is turned on its side or placed upside-down. 
   Yet another aspect of the table is the bracket or retaining member is preferably attached to the table top by a snap, interference or friction fit. Desirably, the bracket is connected to the table top without requiring the use of any fasteners or adhesives, but fasteners or adhesives could be used if desired. 
   A further aspect is the table can be constructed without requiring the use of mechanical fasteners or tools. As discussed above, the frame, legs and retaining members can be secured to the table top without requiring the use of mechanical fasteners. In addition, the legs can be connected to the frame and the support braces without the use of mechanical fasteners. Thus, the table can be assembled without using mechanical fasteners such as screws, bolts, and rivets. Advantageously, this may decrease the cost of the table because fewer components are required to assemble the table. In addition, the table can be more quickly and easily assembled because it does not require the use tools to attach the various components. This may also allow the consumer or purchaser to more easily assemble the table. 
   Another aspect is the table top may include a downwardly extending lip and the inner surface of the lip may include a number of serrations, notches, ribs, and/or struts that are sized and configured to increase the strength, rigidity and/or flexibility of the lip. Advantageously, the uneven inner surfaces of the lip may increase the strength, rigidity and/or flexibility of the table top. In addition, the corners of the table top may also include one or more serrations, notches, ribs, and/or struts that are sized and configured to increase the strength, rigidity and/or flexibility of the corners. 
   A still further aspect of the table is the table top may be constructed from two or more pieces. The two or more pieces are preferably pivotally connected to allow the table top to fold into a compact position. For example, the table top may be constructed from a first piece and a second piece with one or more interlocking portions and one or more overlapping portions. These interlocking and/or overlapping portions allow the two pieces of the table top to be securely interconnected to form a rigid table top. Significantly, the table top constructed from two or more pieces may allow the table to be more easily transported and/or stored because, for example, it may be folded in half. 
   Another aspect is a table with a table top, a leg movable relative to the table top between an extended position and a collapsed position, and a support brace interconnecting the table top and the leg. The support brace includes a first end with an outwardly extending arm with an opening. The table also includes a bracket attached to the leg. The bracket includes a flange with a rounded end and an aperture, the rounded end of the flange being disposed within the opening in the outwardly extending arm and a portion of the outwardly extending arm extends through the aperture in the flange when the support brace is connected to the bracket. Desirably, the first end of the support brace is pivotally connected to the bracket and the first end of the support brace cannot be detached from the bracket when the support brace is connected to the leg and the table top. 
   A still further aspect is a table including a table top, a leg movable relative to the table top between an extended position and a collapsed position, and a support brace interconnecting the leg and the table top. The support brace includes a first end with an outwardly extending arm with an opening. The table also includes a bracket attached to the table top. The bracket includes a first end with an angled portion and an aperture, at least a portion of the angled portion being disposed within the opening in the outwardly extending arm and a portion of the outwardly extending arm extending through the aperture in the bracket when the support brace is connected to the bracket. Preferably, the first end of the support brace is pivotally connected to the bracket. In addition, the first end of the support brace preferably cannot be detached from the bracket when the support brace is connected to the leg and the table top. 
   Another aspect of the table is the second end of the bracket may include an engaging portion and the angled portion at the first end of the bracket may be sized and configured to be inserted into a first recess in the table top. The engaging portion may be sized and configured to be inserted into a second recess in the table top to connect the bracket to the table top. Additionally, the angled portion at the first end of the bracket and the engaging portion at the second end of the bracket may be spaced apart a first distance, and the first recess in the table top and the second recess in the table top are spaced apart a second distance. Desirably, the first distance is smaller than the second distance to connect the bracket to the table top by a friction or interference fit. Further, the table may include a protrusion extending into the first recess and a protrusion extending into the second recess. The angled portion may be sized and configured to contact at least a portion of the protrusion in the first recess when the bracket is connected to the table top, and the engaging portion may be sized and configured to contact at least a portion of the protrusion in the second recess when the bracket is connected to the table top. 
   Yet another aspect is a table with a table top, a leg movable relative to the table top between an extended position and a collapsed position, and a support brace including a first end with an outwardly extending arm with an opening and a second end with an outwardly extending arm with an opening. A first bracket is attached to the leg and the first bracket includes a flange with a rounded end and an aperture. The rounded end of the flange may be disposed within the opening in the outwardly extending arm at the first end of the support brace and a portion of the outwardly extending arm at the first end of the support brace may extend through the aperture in the flange when the support brace is connected to the first bracket. A second bracket is attached to the table top and the second bracket includes a first angled portion and an aperture. At least a portion of the first angled portion may be disposed within the opening in the outwardly extending arm at the second end of the support brace and a portion of the outwardly extending arm at the second end of the support brace may extend through the aperture in the second bracket when the support brace is connected to the second bracket. 
   The table may also include a second outwardly extending arm with an opening located at the first end of the support brace and a second outwardly extending arm with an opening located at the second end of the support brace. A rounded end of the flange of the first bracket may be disposed within the opening in the second outwardly extending arm at the first end of the support brace and a portion of the second outwardly extending arm at the first end of the support brace may extend through a second aperture in the flange when the support brace is connected to the first bracket. At least a portion of the first angled portion of the second bracket being may be disposed within the opening in the second outwardly extending arm at the second end of the support brace and a portion of the second outwardly extending arm at the second end of the support brace may extend through a second aperture in the second bracket when the support brace is connected to the second bracket. 
   The first end of the support brace is preferably pivotally connected to the first bracket and the second end of the support brace is pivotally connected to the second bracket. Advantageously, the first end of the support brace cannot be detached from the first bracket when the support brace is connected to the leg and the table top and the second end of the support brace cannot be detached from the second bracket when the support brace is connected to the leg and the table top. 
   These and other aspects, features and advantages of the present invention will become more fully apparent from the following detailed description of preferred embodiments and appended claims.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
   The present invention is generally directed towards a table with a frame that can be connected to the table top without using mechanical fasteners. The principles of the present invention, however, are not limited to tables with frames that can be connected to table tops without using mechanical fasteners. It will be understood that, in light of the present disclosure, the table disclosed herein can be successfully used in connection with other types of furniture and structures. 
   Additionally, to assist in the description of the table, words such as top, bottom, front, rear, right and left are used to describe the accompanying figures. It will be appreciated, however, that the table can be located in a variety of desired positions—including various angles, sideways and even upside down. A detailed description of the table now follows. 
   As shown in  FIGS. 1 and 2 , the table  10  includes a table top  12  with an upper surface  14 , a lower surface  16 , a first end  18 , a second end  20 , a front side  22  and a rear side  24 . The upper surface  14  of the table top  12  is preferably generally planar to create a smooth, flat working surface, but the upper surface could also be textured and have other suitable configurations depending, for example, upon the intended use of the table  10 . The table top  12  may also include an edge  26  that is disposed about the outer perimeter or periphery of the table top. All or a portion of the edge  26  may be beveled, sloped or rounded to, for example, increase the comfort and safety of the user. The table top  12  may also include a downwardly extending lip  28  disposed near or at the outer portion of the table top. The lip  28  preferably extends downwardly beyond the lower surface  16  of the table top  12  and the lip may be aligned with or form a part of the edge  26  of the table top. It will be appreciated that the lip  28  may also be spaced inwardly from the edge  26  of the table top  12 . Various embodiments of a lip that may be used in conjunction with the table top  12  are disclosed in Assignee&#39;s U.S. Pat. No. 6,550,404, entitled Portable Folding Utility Table with Integral Table Top and Lip, which is hereby incorporated by reference in its entirety. 
   The table top  12  preferably has a generally rectangular configuration with rounded corners and slightly rounded edges  26 . Desirably, the table top  12  has a relatively large size and it is configured for use as a banquet style table. In particular, the table top  12  may have a length of about five feet (or about sixty inches) and a width of about two and one-half feet (or about thirty inches), but the table top can be larger or smaller. For example, the table top  12  could be six or eight feet in length, and the table top could be two or three feet in width. One skilled in the art will appreciate that the table top  12  can be larger or smaller according, for example, to the intended use of the table  10 . Additionally, the table top  12  may have other suitable shapes and configurations such as square, circular, oval, and the like depending, for example, upon the intended use of the table  10 . In addition, the corners and edges  26  of the table top  12  do not have to rounded and, in contrast, the corners and edges could have any desirable configuration, but the rounded features may increase the comfort and/or safety of the user. Further, the table top  12  could be sized and configured for use with other types of tables such as utility tables, card tables, personal-sized tables, and the like. 
   The table top  12  is preferably constructed from a lightweight material and, more preferably, the table top is constructed from plastic, such as high density polyethylene. The plastic table top  12  is desirably formed by a blow-molding process because, for example, it allows a strong, lightweight, rigid and sturdy table top to be quickly and easily manufactured. Advantageously, the blow-molded plastic table top  12  is lighter weight that conventional table tops constructed from wood or metal. The blow-molded plastic table top  12  is lightweight because it is substantially hollow. It will be appreciated that the substantially hollow table top  12  can include table tops that are generally hollow or completely hollow. 
   The table top  12  is preferably constructed from blow-molded plastic because blow-molded plastic table tops are relatively durable, weather resistant, temperature insensitive, corrosion resistant, rust resistant, and blow-molded plastic generally does not deteriorate over time. One skilled in the art, however, will appreciate that the table top  12  does not have to be constructed from blow-molded plastic and other suitable materials and/or processes can be used to construct the table top such as other types of plastics, polymers and synthetic materials. In addition, the table top  12  may be constructed from other materials with sufficient strength and desirable characteristics such as plywood, particle board, solid wood, wood slates, metal alloys, fiberglass, ceramics, graphite, and the like. 
   The upper surface  14  and the lower surface  16  of the table top  12  are spaced apart a given distance and these two spaced apart surfaces help create a rigid and strong table top  12 . Preferably, the upper surface  14  and the lower surface  16  are separated by a generally constant distance so that the surfaces are generally aligned in parallel planes. The upper and lower surfaces  14 ,  16  of the table top  12  may also be interconnected by one or more tack-offs, kiss-offs or depressions  30 , or other reinforcement structures, which may be sized and configured to further increase the strength and rigidity of the table top  12 . Advantageously, the depressions  30  and/or other reinforcement structures can be integrally formed as part of a unitary, one-piece table top  12  during the blow-molding process. 
   The depressions  30  are preferably located in the lower surface  16  of table top  12  and the depressions are preferably sized and configured to increase the strength and structural integrity of the table top. The depressions  30  preferably extend towards the upper surface  14  of the table top and the ends of the depressions  30  may contact or engage the upper surface of the table top  12 , or the ends of the depressions may be spaced from the upper surface of the table top. As shown in  FIGS. 2 and 3 , the depressions  30  preferably cover substantially the entire lower surface  16  of the table top  12 , but it will be appreciated that the depressions may cover only a portion of the table top. Additionally, while the depressions  30  are shown and described as being located in the lower surface  16  of the table top  12 , it will be appreciated that the depressions could be formed in any desired portion of the table top. For example, it will be appreciated that one or more depressions  30  may be formed in the upper surface  14  of the table top  12  and one or more depressions may be formed in the lower surface  16  of the table top, and these opposing depressions may be generally aligned. At least a portion of these opposing depressions  30  may contact or engage each other, but the opposing depressions do not have to touch or engage. 
   The depressions  30  are preferably arranged into a predetermined pattern or array in order to increase the strength and structural integrity of the table top  12 . In particular, the depressions  30  are preferably spaced closely together in a predetermined pattern such that the distance between the depressions is minimized. Advantageously, minimizing the distance between the depressions  30  may minimize the unsupported areas of the upper surface  14  of the table top  12 , which may increase the smoothness of the upper surface of the table top. In addition, minimizing the distance between the depressions  30  may increase the structural integrity and strength of the table top  12 . Thus, the depressions  30  are desirably closely spaced on the lower surface  16  of the table top  12  such that the depressions are separated by a minimum distance in order to create a table top with greater strength, structural integrity, and an upper surface  14  with increased smoothness. 
   Advantageously, the increased structural integrity and strength of the table top  12  may allow the outer wall thickness of the table top to be decreased, which may allow less plastic to be used to construct the table  10 . Because less plastic may be required to construct the table top  12 , that may allow the cost of the table  10  to be decreased. In addition, the blow-molded table top  12  may cool more quickly during the manufacturing process because of the thinner outer wall. This allows the table top  12  to be removed from the manufacturing mold more quickly and it may allow the table top to be removed at a higher temperature because it dissipates heat much more rapidly. Significantly, because the cycle time required to construct the table top  12  may be decreased, the manufacturing efficiency may be increased. 
   The depressions  30  are also preferably arranged in a predetermined pattern with a generally constant and uniform spacing so that the table top  12  has generally uniform characteristics. In particular, the depressions  30  are preferably arranged into a uniform pattern across the entire surface of the table top  12  so that the strength, structural integrity and/or other characteristics of the table top are generally uniform throughout the table top. Thus, the table top  12  has fewer, if any, weak or unsupported portions which decrease the strength and structural integrity of the table top. Thus, the depressions  30  may be used to create a table top  12  with generally uniform characteristics throughout the table top. 
   Desirably, other features formed in the table top  12  are sized and configured such that they do not significantly disturb or disrupt the desired pattern of depressions  30 . In addition, the depressions  30  are preferably integrally formed in the table top  12  as part of a unitary, one-piece structure. Advantageously, the depressions  30  can be integrally formed in the table top  12  during the blow-molding process. Additional details regarding the size, shape and configuration of depressions that are suitable for use in connection with the table top  12  are disclosed in Assignee&#39;s co-pending U.S. patent application Ser. No. 10/409,000, entitled High-Strength, Lightweight Blow-molded Plastic Structures, which is hereby incorporated by reference in its entirety. 
   As best seen in  FIGS. 3 ,  3 A and  4 , a frame  32  is connected to the lower surface  16  of the table top  12 . The frame  32  desirably includes two side rails  34  that extend along the length of the table top  12  and the side rails are preferably positioned near opposing edges  26  of the table top. In particular, the side rails  34  are preferably disposed inwardly from the lip  28  such that there is a gap or space between the side rails and the lip. The side rails  34  preferably extend almost the entire length of the table top  12  to provide increased strength and rigidity for the table top, but the side rails may extend along only a portion of the length of the table and the side rails may not be required to provide increased strength or rigidity to the table top. 
   The frame  32  is desirably constructed from metal, which may easily be formed into the desired configuration by known operations such as stamping and bending, and the metal may be coated or painted as desired. The frame  32  may also include one or more end rails attached to the ends of the side rails  34  and the frame may provide attachment points for the legs, as discussed in more detail below. While the frame  32  preferably includes two side rails  34  that are generally aligned in a parallel configuration, it will be appreciated that the frame may have other suitable configurations and arrangements depending, for example, upon the size and shape of the table top  12  or the intended use of the table  10 . 
   The frame  32  is desirably connected to the lower surface  16  of the table top  12  by one or more frame mounting portions  36  that allow the frame to be connected to the table top by a snap, friction or interference fit. Advantageously, the connection of the frame  32  to the table top  12  does not require the use of mechanical fasteners such as bolts or screws, which desirably expedites the manufacturing or assembly process, but fasteners may be used if desired. Additionally, because screws, bolts and other types of mechanical fasteners are not required to attach the frame  32  to the table top  12 , no holes or other types of stress concentrations are formed in the table top. Thus, the strength and structural integrity of the table top  12  is not compromised by drilling holes in the table top. In addition, because the frame  32  is preferably not bonded to the lower surface  16  of table top  12 , the table top is not weakened or damaged by adhesive. Thus, strength and integrity of the table top  12  may be retained because the frame  32  is not screwed, bolted or bonded directly to lower surface  16  of the table top. Further, the attachment of the frame  32  to the frame mounting portions  36  may reduce the likelihood of deformation or damage to the table top. Finally, the connection of the frame  32  to the table top  12  without using mechanical fasteners or adhesive may facilitate assembly of the table  10  by the retailer or consumer. 
   The frame mounting portions  36  are sized and configured to retain the frame  32  in a generally fixed position and to prevent the unintended removal of the frame from the table top  12 . The frame mounting portions  36  desirably have about the same length as the side rails  34  and this allows the frame  32  to be connected to the frame mounting portions along the entire length of the side rails. Advantageously, any forces acting on the table top  12  and/or the frame  32  are distributed over a large area. In contrast, conventional tables that attached the frame to the table top by mechanical fasteners distributed forces over a much smaller area, which makes conventional tables much more likely to fail. Therefore, the frame mounting portions  36  may provide a very secure attachment of the frame  32  to the table top  12  even though mechanical fasteners are not required. It will be appreciated that the frame mounting portions  36  may have a length less than the frame  32  so that only portions of the frame are attached to the frame mounting portions. 
   As best seen in  FIGS. 3A and 4 , the side rails  34  of the frame  32  preferably have a generally U-shaped configuration with a first side  38 , a second side  40 , and a connecting portion  42 . The first side  38  of the side rail  34  includes an engaging portion  44  and the second side  40  includes an engaging portion  46 . The engaging portions  44 ,  46  are spaced apart a distance and the engaging portions are sized and configured to securely attach the side rails  34  of the frame  32  to frame mounting portions  36 . Because the frame mounting portions  36  are desirably integrally formed in the table top  12  as part of a unitary, one-piece structure, the frame  32  can be directly attached to the table top  12 . 
   As shown in  FIG. 3A , the frame mounting portion  36  includes an opening  48  and a recess  50  that is sized and configured to receive a portion of the side rails  34 . In particular, the opening  48  to the frame mounting portion  36  is preferably slightly smaller than the distance separating the engaging portions  44 ,  46  of the side rails  34 . Thus, when the engaging portions  44 ,  46  of the side rails  34  are inserted into the opening  48 , the engaging portions  44 ,  46  must deflect inwardly and/or the opening must deform to allow the side rails to be inserted into the recess  50  of the frame mounting portion  36 . Once the engaging portions  44 ,  46  are inserted into the recess  50 , the engaging portions and/or the opening  48  resiliently or elastically return to there respective original positions to secure the side rail  34  within the frame mounting portion  36 . 
   The engaging portions  44 ,  46  of the side rails  34  may engage one or more corresponding surfaces within the recess  50  to help secure the frame  32  to the table top  12 . As seen in  FIGS. 3A and 4 , the engaging portions  44 ,  46  are preferably the ends of the first side  38  and second side  40  of the side rail  34  that are bent outwardly at an angle less than about 90° relative to the first and second sides, respectively. The engaging portions  44 ,  46  preferably include sharp edges  52  that are sized and configured to engage corresponding side walls  54 ,  56  of the recess  50 . Advantageously, the sharp edges  52  engage and bite into the softer, blow-molded plastic material of the recess  50  to allow the frame  32  to be securely connected to the table top  12 . Significantly, the engagement of the engaging portions  44 ,  46  and the edges  52  to the recess  50  provides a large contact area between the frame  32  and the frame mounting portions  36 . 
   As seen in  FIGS. 2 ,  3  and  3 A, the frame mounting portions  36  are formed in the lower surface  16  of the table top  12  and one or more depressions  30  are preferably formed in the lower portion of the recess  50  so that a generally consistent, uniform pattern of depressions is formed in the table top  12 . Advantageously, this helps create a table top  12  with increased strength, structural integrity and generally uniform characteristics. One skilled in the art will appreciate that the depressions  30  could have other suitable arrangements and depressions do not have to be formed in the lower portion of the recess  50 . 
   In addition, because at least a portion of the side rails  34  are inserted into the recesses  50 , the side rails and the connecting portion  42  of the frame  32  do not extend a large distance away from the lower surface  16  of the table top  12 . This may allow a table  10  with a low profile to be designed and manufactured. Significantly, if the height of the table top  12  is relatively small, then the tables  10  may be more easily stacked. This may assist in the shipping and storage of the tables  10 . Additionally, the lip  28  may have a height that is larger than or equal to the distance that the side rails  34  extend from the lower surface  16  of the table top  12  so that the frame is generally hidden from view when the table  10  is viewed from a plane generally aligned with the upper surface  14  of the table top  12 . Advantageously, because the frame  32  may be completely or generally hidden from view, the frame does not have to be finished and it may contain visible imperfections or flaws. In addition, because the frame  32  may be completely or generally hidden from view by the lip  28 , a more aesthetically pleasing table  10  may be created. It will be appreciated, however, that the lip  28  does not have to hide all or a portion of the frame  32  from view. 
   As shown in the accompanying figures, the frame  32  engages or abuts several different surfaces of the frame mounting portions  36  to securely attach the frame to the table top  12 . The engagement of the side rails  34  to several different surfaces of the frame mounting portions  36  over an extended length allows any forces or loads on the table top  12  and the frame  32  to be distributed over a large area, which helps prevent failure of the table  10 . Additionally, because the engaging portions  44 ,  46  of the side rails  34  preferably extend outwardly and are spaced wider apart than the opening  48  to the frame mounting portions  36 , a secure snap, friction or interference connection of the frame  32  to the table top  12  may be established. Further, the side rails  34  and the frame mounting portions  36  are preferably generally symmetrical to help prevent undesirable twisting of the frame  32  and/or table top  12 . 
   Advantageously, the frame  32  can be quickly and easily connected to the table top  12  by inserting the engaging portions  44 , 46  of the side rails  34  into the openings  48  in the frame mounting portions  36 . As discussed above, mechanical fasteners such as screws or bolts are not required to connect the frame  32  to the table top  12 , but such fasteners may be used if desired. In addition, the frame  32  can be more easily disconnected from the table top  12 , if desired, because mechanical fasteners do not have to be removed. Other suitable embodiments for connecting a frame to a table top are disclosed in Assignee&#39;s co-pending U.S. patent application Ser. No. 10/409,259, entitled Frame That Can Be Attached to a Table Top without Mechanical Fasteners, which is hereby incorporated by reference in its entirety. 
   As best seen in  FIGS. 4 ,  6  and  7 , the side rails  34  of the frame  32  include openings  60  that are sized and configured to allow legs  62 ,  64  to be attached to the table  10 . The legs  62 ,  64  are sized and configured to support the table top  12  above a surface such as a floor and the legs may be adjustable in length. The legs  62 ,  64  are preferably disposed between the side rails  34  of the frame and the openings  60  are preferably located near the ends of the side rails  34  in generally aligned pairs. It will be appreciated that the openings  60  could be positioned in any desired locations depending, for example, the configuration of the legs  62 ,  64  and/or the frame  32 . 
   The openings  60  preferably have a non-circular configuration such as oval, oblong, egg-shaped, kidney-shaped, key-shaped, etc., which is sized and configured to receive a portion of the legs  62 ,  64 . As shown in the accompanying figures, the openings  60  include a length  66  that is generally aligned with the longitudinal length of the side rails  34  and a height  68  that is generally aligned with the height of the side rails. It will be appreciated that one or more bushings, sleeves, bearings, and the like may be used in conjunction with openings  60  to facilitate the connection of the legs  62 ,  64  to the frame. 
   The legs  62 ,  64 , which are movable between a first extended position in which the legs extend away from the table top  12  and a second collapsed position in which the legs are positioned near the table top for storage, include a connecting rod  70  that is sized and configured to be inserted into the openings  60  in the side rails  34  of the frame  32 . The rotation of the connecting rod  70  within the opening  60  allows the legs  62 ,  64  to move between the first and second positions relative to the table top  12 . 
   As best seen in  FIGS. 2 and 3 , the lower surface  16  of the table top  12  includes receiving channels  72  that are sized and configured to receive at least a portion of the legs  62 ,  64  in the collapsed position. The receiving channels  72  advantageously receive at least a portion of the legs  62 ,  64  to decrease the height of the table  10  in the storage position. This allows more tables  10  to be stacked and stored in a limited amount of space, and this may facilitate shipping and transportation of the tables. As shown in the accompanying figures, one or more depressions  30  are preferably located in the receiving channels  72  so that the consistent pattern and arrangement of depressions is maintained. It will be appreciated, however, that depressions  30  do not have to be formed in the receiving channels  72  and receiving channels do not have to be formed in the table top  12 . 
   The connecting rod  70  preferably has a non-circular cross-sectional configuration and the openings  60  in the side rails  34  of the frame  32  also preferably have a non-circular configuration. For example, the openings  60  and the connecting rod  70  may have a configuration that is oval, oblong, egg-shaped, kidney-shaped, key-shaped, etc. Desirably, the non-circular opening  60  and the non-circular cross-sectional configuration of the connecting rod  70  are sized and configured such that the connecting rod is not securely held within the opening when the legs are in the collapsed position. Thus, in the collapsed position, one or more small gaps or spaces are located between connecting rod  70  and the opening  60  so that the connecting rod can move slightly within the opening. Advantageously, this allows the legs  62 ,  64  to be more easily connected to the side rails  34  because of the larger clearance. 
   Additionally, because there is some movement or “play” between the legs  62 ,  64  and the side rails  34  when the legs are in the collapsed position, that may allow the legs to fold flatter such that the legs contact and/or are generally parallel to the lower surface  16  of the table top  12 . Further, the movement of the legs  62 ,  64  within the openings  60  may allow the legs to be positioned in the desired collapsed position even if, for example, there is some slight imperfection in the table  10  or if a portion of the table has expanded or contracted due to temperature. Accordingly, the tables  10  may be more easily manufactured and assembled because of the greater tolerances, and the tables may fold flatter to facilitate stacking of the tables. 
   When the legs  62 ,  64  are in the extended position, however, the connecting rod  70  is preferably securely held within the openings  60  to rigidly and securely attach the legs to the table top  12 . In particular, when the connecting rod  70  is rotated within the openings  60  to the extended position, the connecting rod and openings are sized and configured such that there is no or very little movement or play between the connecting rod and the openings. Thus, the legs  62 ,  64  desirably do not shake or wobble in the extended position. 
   For example, the openings  60  in the side rail  34  may have a height of about 0.94 ({fraction (15/16)}) inches and an overall length of about 1.5 inches, and the connecting rod  70  may have an oval configuration with a height of about 0.94 ({fraction (15/16)}) inches and a width of about 0.75 (¾) inches. Advantageously, these sizes and configurations allow the connecting rod  70  to be relatively easily inserted into the openings  60  and the connecting rod can move slightly within the opening when the legs  62 ,  64  are in the collapsed position. In particular, as best seen in  FIG. 6 , the connecting rod  70  can move within the opening  60  because there are gaps or spaces between the connecting rod and the opening. On the other hand, when the legs  62 ,  64  are in the extended position, the connecting rod  70  is securely held within the opening  60 . As best seen in  FIG. 7 , the upper and lower ends of the connecting rod  70  engage the upper and lower portions of the opening  60  when the legs  62 ,  64  are in the extended position. 
   It will be appreciated that the openings  60  and connecting rod  70  can have other suitable sizes and configurations depending, for example, upon the size and/or intended use of the table  10 . It will also be appreciated that other suitable combinations of the openings  60  and connecting rod  70  may be utilized, such as the combination of generally circular openings and non-circular connecting rods, or non-circular openings and generally circular connecting rods. Further, it will be appreciated that the legs  62 ,  64  may be attached to the frame  32  or table top  12  by other suitable types of devices and mechanisms. 
   The legs  62 ,  64 , as best seen in  FIGS. 4 and 5 , are attached to or include the connecting rod  70  and the legs include a pair of elongated support members  74 ,  76  and a foot portion  78 . Advantageously, the two separate elongated support members  74 ,  76  may help prevent twisting or torque on the connection of the support members to the connecting rod  70  and the foot portion  78 . Additionally, while the elongated support members  74 ,  76  are preferably welded to the connecting rod  70  and the foot portion  78 , the support members may be connected to the connecting rod and foot portion by any suitable method or device. 
   As best seen in  FIG. 5 , the elongated support members  74 ,  76  preferably have a generally curved configuration. In particular, the upper portions of the elongated support members  74 ,  76  are preferably spaced apart to provide a secure attachment of the support members to the connecting rod  70 , the middle portions of the elongated support members are preferably more closely spaced together, and the lower portions of the elongated support members are spaced apart to provide a secure connection to the foot portion  78 . The foot portion  78  preferably has an upwardly extending curved section and feet  82  may be connected to the ends of the foot portion. A connecting member  80  is preferably disposed near the middle portion of the elongated support members  74 ,  76  to help maintain the support members in the desired positions. 
   The connecting rod  70 , elongated support members  74 ,  76  and foot portion  78  of the legs  62 ,  64  are desirably constructed from hollow metal tubes because the metal tubes are relatively lightweight and strong. The hollow metal tubes forming the connecting rod  70 , elongated support members  74 ,  76  and foot portion  78  desirably have a generally oval configuration to provide increased strength. Advantageously, the oval configuration may also be used to create a thinner profile for the legs  62 ,  64 , which may create a thinner profile for the table  10  when the legs are in the collapsed position. 
   It will be appreciated that the legs  62 ,  64  may be constructed from other materials with the suitable characteristics and the legs may have other shapes and configurations depending, for example, upon the intended use of the table  10 . For example, the legs  62 ,  64  may include only a single elongated support member or multiple elongated support members, and the legs may be constructed as a single component or multiple components that are connected together. It will further be appreciated that the legs  62 ,  64  need not be in pivotal engagement with frame  32  or the table top  12  to be collapsible. For example, the legs  62 ,  64  may be detachably connected to the table top  12  such that when it is desired to collapse the table  10  for storage, the legs are detached from the table top. Other suitable embodiments for connecting legs to a table top are disclosed in Assignee&#39;s U.S. patent application Ser. No. 10/408,917, entitled Pivotal Connection of a Table Leg to a Frame, which is hereby incorporated by reference in its entirety. 
   A support brace  84  is used to support the legs  62 ,  64  in the extended position. The support brace  84  includes a first end  86  that is attached to the leg  62 ,  64  and a second end  88  that is attached to the table top  12  by a mounting member or bracket  90 . The support brace  84  is preferably pivotally connected to the leg  62 ,  64  and the bracket  90  to allow the leg to be moved between the extended and collapsed positions. It will be appreciated that while the legs  62 ,  64  are in the extended or collapsed positions, the support brace  84  is also in a corresponding extended or collapsed position. Advantageously, the support brace  84  can be connected to the leg  62 ,  64  and the bracket  90  without the use of mechanical fasteners such as screws, rivets or bolts. Significantly, the table  10  may be built more quickly because fewer components may be required to assemble the table and no mechanical fasteners are needed to attach the support brace  84  to the legs  62 ,  64  or the table top  12 . It will be appreciated, however, that one or more mechanical fasteners may be used to connect the support brace  84  to the leg  62 ,  64  and/or the table top  12 . 
   In greater detail, as best seen in  FIGS. 10 ,  11  and  12 , the first end  86  of the support brace  84  includes two curved arms  92  and each curved arm has an opening  94  that leads to a generally circular interior portion  96 . The two generally circular interior portions  96  are generally aligned along the same axis and disposed at the end  86  of the support brace  84 . The generally circular interior portions  96  are sized and configured to receive corresponding receiving portions  98  formed in the connecting member  80 . In particular, the receiving portions  98  include a flange  100  with rounded ends  102  and corresponding openings  104 . The support brace  84  is connected to the leg  62 ,  64  by disposing the rounded ends  102  of the flange  100  within the generally circular interior portions  96  of the curved arms  92 . In addition, the curved arms  92  of the support brace  84  are disposed within the openings  104  in the connecting member  80 . Advantageously, when the support brace  84  is connected to the legs  62 ,  64  and the table top  12 , the support brace cannot be inadvertently disconnected from the legs. While this connection of the support brace  84  to the leg  62 ,  64  does not require that use of any mechanical fasteners, it will be appreciated that mechanical fasteners may be used to connect the support brace to the legs  62 ,  64 . 
   In order to attach the support brace  84  to the leg  62 ,  64 , the two generally circular interior portions  96  of the curved arms  92  are coaxially aligned with the rounded ends  102  of the flange  100 . The rounded ends  102  of the flange  100  are then inserted into the generally circular interior portions  96  of the support brace  84  and the arms  92  are inserted into the openings  104  in the flange. Significantly, when the second end  88  of the support brace  84  is attached to the table top  12 , the first end  86  of the support brace cannot be disconnected from the leg  62 ,  64 . This helps create a strong and secure table  10  because the support brace  84  cannot be unintentionally disconnected from leg  62 ,  64  when the table is assembled. However, when the second end  88  of the support brace  84  is disconnected from the table  10 , then the first end  86  of the support brace can be disconnected from the leg  62 ,  64 . This allows the table  10  to be quickly and easily assembled, and it allows the table to be quickly and easily disassembled. 
   The brackets  90 , as best seen in  FIGS. 3 and 3B , are connected to the lower surface  16  of the table top  12  by bracket mounting portions  110  that allow the brackets to be connected to the table top by a snap, friction or interference fit. Advantageously, the connection of the brackets  90  to the table top  12  does not require the use of mechanical fasteners such as bolts or screws, which desirably expedites the manufacturing or assembly process, but fasteners may be used if desired. Additionally, because screws, bolts or other types of mechanical fasteners are not required to attach the brackets  90  to the table top  12 , no holes or other types of stress concentrations are formed in the table top. Thus, the strength and structural integrity of the table top  12  is not diminished by drilling or forming holes in the table top. In addition, because the brackets  90  are preferably not glued to the lower surface  16  of table top  12 , the table top is not weakened or damaged by adhesive. Thus, strength and integrity of the table top  12  may be retained because the brackets  90  are not screwed, bolted or bonded to bottom surface  16  of the table top. Further, the connection of the brackets  90  to the table top  12  without using mechanical fasteners or adhesives may facilitate assembly of the table  10  by the retailer or consumer. 
   The bracket mounting portions  110  are sized and configured to retain the brackets  90  in generally fixed positions and to prevent the unintended removal of the brackets from the table top  12 . Advantageously, the brackets  90  engage a relatively large portion of the table top  12  so that forces applied to the brackets are distributed over a large area. This provides an improved and more secure connection of the brackets  90  to the table top  12  because forces are distributed over a much larger area than brackets attached to a table top only by mechanical fasteners. Additionally, the connection of the brackets  90  to the table top  12  by the bracket mounting portions  110  may be less likely to fail than conventional brackets attached to a table top by mechanical fasteners because of the larger engagement area. 
   As best seen in  FIG. 3B , the bracket  90  includes a main body portion  112  with a first end  114  and a second end  116 . The first end  114  of the bracket  90  includes an engaging portion  118  with a rounded flange  120  and an edge  122 . The second end  116  of the bracket  90  includes a retaining portion  124  with a first angled portion  126  and a second angled portion  128 . The first angled portion  126  is preferably disposed at an angle less than about 90° with respect to the main body portion  112  of the bracket  90  so that it is angled towards the first end  114  of the bracket  90 . As discussed below, the engaging portion  118  and the retaining portion  124  are sized and configured to securely attach the bracket  90  to bracket mounting portion  110  by a snap, friction or interference fit. Additionally, the bracket  90  is preferably directly attached to the table top  12  because the bracket mounting portions  110  are desirably integrally formed in the table top as part of a unitary, one-piece structure. It will be appreciated, however, that the bracket  90  does not have to be directly attached to the table top  12  and the bracket does not have to be attached to the table top by the bracket mounting portions  110 . 
   As shown in  FIG. 3B , the bracket mounting portion  110  includes a first recess  130  and a second recess  132  that are sized and configured to receive the first end  114  and the second end  116  of the bracket  90 , respectively. In particular, the first recess  130  is disposed towards the middle of the table top  12  and the first recess preferably has a length that is approximately the same as the length of the first end  114  of the bracket  90 . A protrusion or lip  134  projects into an upper portion of the first recess  130  and it is sized and configured to fit within the inner portion of the rounded flange  120  on the first end  114  of the bracket  90 . The second recess  132  is disposed towards the end of the table top  12  and it has a length that is approximately the same as the length of the second end  116  of the bracket  90 . A protrusion or lip  136  extends into an upper portion of the second recess  132  and it is sized and configured to contact or abut at least a portion of the first downwardly extending portion  126  on the second end  116  of the bracket  90 . The distance from the first edge  122  on the first end  114  of the bracket  90  to the innermost part of the first downwardly extending portion  126  on the second end  116  of the bracket is preferably smaller than the distance from the protrusion  134  extending into the first recess  130  to the protrusion  136  extending into the second recess  132  of the bracket mounting portion  110 , which allows the bracket to be connected to the bracket mounting portion  110  by a snap, friction or interference fit. 
   In order to connect the bracket  90  to the table top  12 , the engaging portion  118  on the first end  114  of the bracket is inserted into the first recess  130  of the bracket mounting portion  110  such that the rounded flange  120  and the edge  122  engage a portion of the table top  12 . In particular, the edge  122  preferably engages a portion of the first recess  130  and/or the protrusion  134  and the rounded flange  120  contacts or abuts at least a portion of the protrusion. The second end  116  of the bracket  90  is then inserted into the second recess  132  of the bracket mounting portion  110 . As the retaining portion  124  on the second end  116  of the bracket  90  is inserted into the second recess  132 , the first angled portion  126  and/or the protrusion  136  deflects or deforms to allow the second end of the bracket to be inserted into the recess. Once the second end  116  of the bracket  90  is inserted into the second recess  132 , the first angled portion  126  and/or the protrusion  136  resiliently or elastically returns to there original positions to secure the second end of the bracket in a fixed position. Accordingly, the bracket  90  is preferably connected to the bracket mounting portion  110  of the table top  12  by a snap, friction or interference fit, and this allows the bracket to be securely connected to the table top without the use of fasteners. It will be appreciated, however, that fasteners or adhesives could also be used to secure the bracket  90  to the table top  12  if desired. 
   The rounded flange  120  on the first end  114  of the bracket  90  preferably has a radius of curvature that generally corresponds to the radius of curvature of the protrusion  134  to help secure the bracket  90  to the bracket mounting portion  110 . Similarly, the first angled portion  126  on the second end  116  of the bracket  90  preferably has a radius of curvature that generally corresponds to the radius of curvature of the protrusion  136 . This provides a large contact area between the bracket  90  and the bracket mounting portion  110 . Additionally, the edge  122  on the first end  114  of the bracket  90  is preferably sharp so that it engages and bites into the softer, blow-molded plastic material of the table top  12  to allow the bracket  90  to be securely connected to the table top. Significantly, the engagement of the first end  114  and the second end  116  of the bracket  90  to the first recess  130  and the second recess  132  of the bracket mounting member  110 , respectively, provides a large contact area that allows forces or loads on bracket to be distributed over a large area, which helps provide a secure and durable connection of the support brace  84  to the table top  12 . 
   As seen in  FIG. 2 , the bracket mounting portions  110  are formed in the lower surface  16  of the table top  12  and one or more depressions  30  may be formed in the bracket mounting portions so that a generally consistent, uniform pattern of depressions is formed in the table top  12 . Significantly, all or only a portion of the depressions  30  may be formed in the bracket mounting portions  110  in order to maintain the generally uniform pattern of depressions. Advantageously, the uniform pattern of depressions  30  may help create a table top  12  with increased strength, structural integrity and generally uniform characteristics. One skilled in the art will appreciate that the depressions  30  could have other suitable arrangements and depressions do not have to be formed in the bracket mounting portions  110 . 
   As discussed above, the second end  88  of the support brace  84  is connected to the bracket  90 . As best seen in  FIGS. 4 and 14 , the second end  88  of the support brace includes two curved arms  93  and each curved arm has an opening  95  that leads to a generally circular interior portion  97 . The two generally circular interior portions  97  are generally aligned along the same axis and disposed near the end of the support brace  84 . The generally circular interior portions  97  are sized and configured to be connected to the second end  116  of the bracket  90 . In particular, the generally circular interior portions  97  are sized and configured to receive a portion of the first angled portion  126  and the second angled portion  128  of the bracket  90 . In addition, the curved arms  93  of the support brace  84  are configured to be disposed within openings  99  in the second end  116  of the bracket  90 . Advantageously, when the support brace  84  is connected to the legs  62 ,  64  and the table top  12 , the support brace cannot be inadvertently disconnected from the bracket  90 . While this connection of the support brace  84  to the bracket  90  does not require that use of any mechanical fasteners, it will be appreciated that mechanical fasteners may be used to connect the support brace to the bracket. 
   In order to attach the support brace  84  to the bracket  90 , the two generally circular interior portions  97  of the curved arms  93  are coaxially aligned with the first angled portion  126  and the second angled portion  128  on the second end  116  of the bracket. The first angled portion  126  and the second angled portion  128  are then inserted into the generally circular interior portions  97  of the support brace  84  and the curved arms  93  are inserted into the openings  99  in the second end  116  of the bracket  90 . Significantly, when the support brace  84  is connected to the bracket  90  and the bracket is connected to the table top  12 , the support brace cannot be disconnected from the bracket. This helps create a strong and secure table  10  because the support brace  84  cannot be unintentionally disconnected from bracket  90  when the table is assembled. However, when the bracket  90  is disconnected from the table top  12 , then the second end  88  of the support brace  84  can be disconnected from the bracket. This allows the table  10  to be quickly and easily assembled and disassembled. 
   As discussed above, the first end  86  of the support brace  84  may be pivotally connected to the legs  62 ,  64  and the second end  88  of the support brace may be pivotally connected to the bracket  90 . One skilled in the art, however, will appreciate that the ends  86 ,  88  of the support brace  84  do not have to be pivotally connected to the legs  62 ,  64  or the bracket  90 . 
   As best seen in  FIGS. 7-10 , the support brace  84  includes a first arm  140  that is pivotally connected to a second arm  142  by a pin  144 . The pivotal connection of the first and second arms  140 ,  142  allows the support brace  84  to move between the extended position and the collapsed position. When the support brace  84  is in the collapsed position, the legs  62 ,  64  are also in the collapsed position. Similarly, when the support brace  84  is in the extended position, the legs  62 ,  64  are also in the extended position. While the support brace  84  preferably pivots to allow the legs  62 ,  64  to be moved between the extended position and the collapsed position, it will be understood that the support brace does not require the pivotal connection of the first arm  140  and the second arm  142 , and the support brace  84  could have other suitable arrangements and/or configurations. 
   A locking mechanism  146  is preferably used to secure the support brace  84  in the extended position, which consequently also secures the legs  62 ,  64  in the extended position. Advantageously, the locking mechanism  146  can secure the legs  62 ,  64  in the extended position regardless of the position or orientation of the table  10 . Thus, the legs  62 ,  64  will not move from the extended position to the collapsed position even if the table  10  is turned on its side or upside-down. In addition, the locking mechanism  146  is preferably biased to remain in the locked position and the locking mechanism positively locks the support brace  84  and the legs  62 ,  64  in the extended position. Further, the locking mechanism  140  preferably requires the user to intentionally unlock the mechanism to allow the support brace  84  and the legs  62 ,  64  to move into the collapsed position. Thus, the support brace  84  and the legs  62 ,  64  can be positively held in the extended position by the locking mechanism  146 . 
   As seen in  FIGS. 8-10 , the locking mechanism  146  includes an elongated body  148  that is generally sized and configured to fit within the second arm  142  of the support brace  84 . In particular, the second arm  142  of the support brace  84  has a generally U-shaped configuration with two opposing sidewalls  150 ,  152  and the elongated body  148  of the locking mechanism  146  is generally disposed between the sidewalls and towards the end of the second arm nearest the first arm  140 . The elongated body  148  of the locking mechanism  146  includes a first end  154  that is sized and configured to engage the pin  144  and a second end  156  with an elongated extension  158 . Two outwardly extending tabs or flanges  160 ,  162  are disposed between the ends  154 ,  156  of the locking mechanism  146  and the tabs extend through an opening  164  in the second arm  142  of the support brace  84 . The elongated extension  158  on the second end  156  of the locking mechanism  146  extends through an opening  166  in a flange  168  extending from the second arm  142  of the support brace  84 . A biasing member such as a spring  170  is disposed about the elongated extension  158  and the biasing member is positioned between the flange  168  and the elongated body  148  of the locking mechanism  146 . 
   The locking mechanism  146  is movable relative to the second arm  142  between a locked position in which the elongated body  148  is disposed proximate the end of the second arm nearest the first arm  140 , and an unlocked position in which the elongated body is disposed inwardly from the end of the second arm and away from the first arm. The spring  170  is desirably sized and configured to bias the locking mechanism  146  into the locked position. In this locked position, the first end  154  of the elongated body  148  contacts the pin  144  and the outwardly extending tabs  160 ,  162  are disposed towards the end of the second arm  142  of the support brace  84 . In the unlocked position, the first end  154  of the elongated body  148  is spaced apart from the pin  144  and the outwardly extending tabs  160 ,  162  are spaced away from the end of the second arm  142  of the support brace  84 . One skilled in the art will appreciate that other suitable types of biasing mechanisms may be used to bias the locking mechanism  146  into the locked position. 
   The first and second arms  140 ,  142  of the support brace  84  are generally aligned and at least a portion of the arms overlap when the support brace is in the extended position. In particular, as best seen in  FIGS. 8 and 9 , the first arm  140  of the support brace  84  includes two extensions  172 ,  174  and the extensions are generally parallel to and overlap portions of the sidewalls  150 ,  152  of the second arm  142  when the support brace is in the extended position. When the locking mechanism  146  is in the locked position, the locking mechanism maintains the extensions  172 ,  174  in the generally parallel and overlapping position with the sidewalls  150 ,  152  of the second arm  142 . Specifically, the outwardly extending tabs  160 ,  162  engage the extensions  172 ,  174  to prevent the first arm  140  from moving relative to the second arm  142 . Thus, the outwardly extending tabs  160 ,  162  prevent the first arm  140  from pivoting relative to the second arm  142 , and that maintains the support brace  84  and the legs  62 ,  64  in the extended position. 
   On the other hand, when the support brace  84  is in the collapsed position, the extensions  172 ,  174  do not overlap portions of the sidewalls  150 ,  152  of the second arm  142  of the support brace  84 . In contrast, as best seen in  FIG. 6 , the extensions  172 ,  174  are spaced away from the second arm  142  of the support brace  84  and at least a portion of the second arm may be disposed inside the body of the first arm  140  to form a small, compact arrangement. Advantageously, the support brace  84  does not significantly protrude from the lower surface  16  of the table top  12  in the collapsed position. This allows a table  10  with a relatively small height when the legs  62 ,  64  are in the collapsed position to be constructed, if desired. 
   When the locking mechanism  146  is in the unlocked position, the locking mechanism does not secure the support brace  84  in the extended position. In contrast, the locking mechanism  146  allows the first and second arms  140 ,  142  of the support brace  84  to freely move with respect to each other. In particular, as shown in  FIG. 10 , when the user moves the locking mechanism  146  into the unlocked position, the outwardly extending tabs  160 ,  162  no longer engage the extensions  172 ,  174  and that allows the first and second arms  140 ,  142  of the support brace  84  to freely rotate. Desirably, when the user releases the locking mechanism  146 , the spring  170  causes the locking member to return to its locked position. 
   As best seen in  FIGS. 6 ,  9  and  10 , the extensions  172 ,  174  have a curved front surface  176  and a generally straight rear surface  178  to positively secure the locking mechanism  146  in the locked position, and to allow the support brace  84  to be moved from the collapsed position to the extended position without the user unlocking the locking mechanism  146 . In particular, the curved front surfaces  176  of the extensions  172 ,  174  are sized and configured to engage the outwardly extending tabs  160 ,  162  of the locking mechanism  146  when the support brace  84  is moved from the collapsed position to the extended position. Specifically, the curved front surfaces  176  engage the outwardly extending tabs  160 ,  162  and push the locking member  146  into the unlocked position. When the support brace  84  is in the extended position and the first and second arms  140 ,  142  are generally aligned, the curved front surface 3   176  of the extensions  172 ,  174  no longer engage the tabs  160 ,  162  and the spring  170  returns the locking mechanism  146  to the locked position. Thus, the locking member  146  allows the support brace  84  to be moved from the collapsed position to the extended position without requiring the user to unlock the locking mechanism. 
   The generally straight rear surfaces  178  of the extensions  172 ,  174  prevent the locking mechanism  146  from being inadvertently unlocked and allowing the support brace  84  to move from the extended position to the collapsed position. In particular, the generally straight rear surfaces  178  of the extensions  172 ,  174  engage the generally planar lower surfaces of the tabs  160 ,  162 , and this engagement of the extensions and tabs prevents the support brace  84  from moving from the extended position to the collapsed position. In order to allow the support brace  84  to move from the extended position to the collapsed position, the user must intentionally unlock the locking mechanism  146 , and this allows the support brace and the legs  62 ,  64  to be collapsed. 
   Significantly, the locking mechanism  146  is lightweight and includes few moving parts. In particular, the locking mechanism  146  is preferably constructed from metal and it can be stamped or formed into the desired configuration. Additionally, the second arm  140  is preferably constructed from metal and the opening  164 , opening  166  and flange  168  can be stamped or formed into the desired configuration. While the first arm  140 , second arm  142  and the locking mechanism  146  are preferably unitary components, it will be appreciated that these components may be constructed from multiple parts that are connected together. Further, these components may have other suitable configurations and arrangements depending, for example, upon the size and/or intended use of the table  10 . 
   In operation of the locking mechanism  146 , when the second arm  142  is in the collapsed position and being rotated into the extended position, the curved front surfaces  176  of the extensions  172 ,  174  engage the outwardly extending tabs  160 ,  162 . The rotation of the second arm  142  relative to the first and  140  causes the extensions  172 ,  174  to push the outwardly extending tabs  160 ,  162  and the locking member  146  into the unlocked position. When the support brace  84  is in the extended position, the extensions  172 ,  174  no longer engage the outwardly extending tabs  160 ,  162  and the spring  170  forces the locking mechanism  146  into the locked position. Alternatively, instead of the extensions  172 ,  174  moving the locking mechanism  146  into the unlocked position while the support brace  84  is being moved from the collapsed position to the extended position, the user may manually move the locking mechanism into the unlocked position. In order to move the support brace  84  and legs  62 ,  64  from the extended position to the collapsed position, the user slides the locking mechanism  146  into the unlocked position, as shown in  FIG. 10 , which allows the second arm  142  to rotate relative to the first arm  140 . Once the arms  140 ,  142  are not longer in the extended position, the user can release the locking mechanism  146  and position the legs  62 , 64  in the collapsed position. Other suitable types of locking mechanisms for retaining table legs in an extended position are disclosed in Assignee&#39;s co-pending U.S. patent application Ser. No. 10/408,949, entitled Table Leg Locking Mechanism, which is hereby incorporated by reference in its entirety. 
   As shown in  FIGS. 15-17 , one or more clips  180  are desirably attached to the table top  12  and the clips are sized and configured to hold the legs  62 ,  64  in the collapsed or storage position. In particular, as seen in  FIG. 3 , the clips  180  receive and retain the legs  62 ,  64  such that the legs are generally parallel to and proximate the lower surface  16  of the table top  12 . Desirably, at least a portion of the legs  62 ,  64  are located within the channels  72  formed in the lower surface  16  of the table top  12  so that the height of the table top can be minimized when the legs are in the collapsed position. As shown in  FIG. 3 , a single clip  180  may be used to receive and retain each leg  62 ,  64  in the collapsed position. It will be appreciated, however, that any suitable number of clips  180  may be used to retain the legs  62 ,  64  in the collapsed position. It will also be appreciated that the table  10  does not require the clip  180  to secure the legs  62 ,  64  in the collapsed position and other suitable devices may be used to secure the legs in the collapsed position. For example, one or more securing members as disclosed in Assignee&#39;s U.S. Pat. No. 6,530,331, entitled Portable Folding Utility Table with Integral Receiving Members, which is hereby incorporated by reference in its entirety, may be used to secure the legs in the collapsed position. 
   The clip  180  includes a body  182  that is sized and configured to be inserted into a corresponding receiving portion  184  formed in the table top  12 , and the receiving portion desirably has the same general size and shape as one of the depressions  30 . Thus, while the receiving portion  184  may be placed in any suitable location, it is desirably positioned so that it does not interrupt or disturb the generally uniform pattern of depressions  30 . Accordingly, the receiving portion  184  may allow the table top  12  to be constructed with generally uniform characteristics, such as generally consistent strength and structural integrity, because the receiving portion may act or function similar to one of the depressions  30 . 
   As best seen in  FIGS. 16 and 17 , the clip  180  includes a leg receiving portion  186  that is sized and configured to receive and retain a leg  62 ,  64  of the table  10 . The leg receiving portion  186  preferably receives and retains the leg  62 ,  64  in a snap, friction or interference fit. In particular, the leg receiving portion  186  includes an opening  188  that is smaller than the corresponding portion of the leg  62 ,  64  that is intended to be received by the receiving portion. Thus, when the leg  62 ,  64  is inserted into the opening  188 , the clip  180  deforms to increase the size of the opening and allow the leg to be inserted into the leg receiving portion  186 . The clip  180  then elastically or resiliently returns to its original position to receive and retain the leg  62 ,  64  within the leg receiving portion  186 . 
   The clip  180  also includes a retaining portion  190  that allows the clip to be connected to the table top  12 . The retaining portion  190  has a generally U-shaped configuration with opposing sidewalls  192 ,  194  and a lower surface  196 . The opposing sidewalls  192 ,  194  include outwardly extending projections  198 ,  200 , respectively, that are sized and configured to securely connect the clip  180  to the table top  12 . In particular, as best seen in  FIG. 17 , the receiving portion  184  formed in the table top  12  includes an opening  202  that is desirably sized smaller than at least a portion of the width of the retaining portion  190  of the clip  180 . When the retaining portion  190  of the clip  180  is inserted into the opening  202 , the retaining portion and/or the opening deform or deflect to allow the retaining portion to be inserted into the receiving portion  184 . The opening  202  and/or the retaining portion  190  then resiliently or elastically return to there original positions to secure the clip  180  within the receiving portion  184 . 
   Additionally, the receiving portion  184  includes opposing sidewalls  204 ,  206  and a bottom surface  208  and at least a portion of these surfaces are intended to contact corresponding portions of the clip  180 . Specifically, the sidewalls  204 ,  206  of the receiving portion  184  are designed to contact the sidewalls  192 ,  194  of the retaining portion  190  of the clip  180 , and the projections  198 ,  200  are intended to bite into and engage the sidewalls of the receiving portion. The relatively large contact area between the retaining portion  190  of the clip  180  and the receiving portion  184  in the table top  10 , and the engagement of the projections  198 ,  200  with the sidewalls  204 ,  206  of the receiving portion, allows the clip to be securely connected to the table top  12 . 
   Advantageously, the clips  180  can be quickly and easily connected to the table top  12 , which may speed the manufacturing process. The clips  180  also allow the legs  62 ,  64  to be secured in the collapsed position regardless of the position or orientation of the table  10 . In addition, the clips  180  may be disconnected from the table top  12 , if desired. Significantly, the clips  180  can be attached to the table top  12  without the use of mechanical fasteners such as screws or bolts, but mechanical fasteners may be used to attach the clips to the table top if desired. Further, it will be appreciated that the clips  180  may have other suitable sizes and configurations depending, for example, upon the size and configuration of the receiving portion  184  formed in the table top  12 . Other suitable embodiments for the clip are disclosed in Assignee&#39;s co-pending U.S. patent application Ser. No. 10/409,259, entitled Frame That Can Be Attached to a Table Top without Mechanical Fasteners, which was previously incorporated by reference in its entirety. 
   As shown in  FIGS. 2 ,  3  and  18 , the lip  28  is preferably disposed near or at the outer portion of the table top  12 . As discussed above, the lip  28  preferably extends downwardly beyond the lower surface  16  of the table top  12  and the lip may be aligned with or form part of the edge  26  of the table top, but the lip may also be spaced inwardly from the edge of the table top. As best seen in  FIG. 18 , the lip  28  includes an inner surface  210  and a lower surface  212 , and the lip preferably has a generally hollow interior. Advantageously, the lip  28  may be integrally formed during the blow-molding process as part of a unitary, one-piece table top  12 . It will be appreciated, however, that the lip  28  does not have to be formed as a unitary component of the table top  12 . 
   The lower surface  212  of the lip  28  desirably has a smooth, planar surface that facilitates stacking of the tables  10 . The inner surface  210  of the lip  28 , however, includes a number of serrations, notches, ribs, and/or struts that are sized and configured to increase the strength, rigidity and/or flexibility of the lip  28 . In particular, the inner surface  210  of the lip  28  may include a number of notches, indentations, grooves or other inwardly extending portions  216  to form an uneven or saw-tooth type surface. The inner surface  210  may also include a number of bumps, humps, protrusions or other outwardly extending portions  218  to form an uneven or saw-tooth type surface. The inner surface  210  of the lip  28  may also contain a combination of inwardly and outwardly portions  216 ,  218  to form the uneven or saw-tooth type surface. 
   Advantageously, the uneven inner surfaces  210  of the lip  28  may increase the strength, rigidity and/or flexibility of the lip  28 , which may increase the strength, rigidity and/or flexibility of the outer portions of the table top  12 . For example, the uneven inner surfaces  210  of the lip  28  may allow the outer portions of the table top  12  to absorb more energy or larger impacts than conventional planar surfaces. Additionally, the uneven inner surfaces  210  of the lip  28  may absorb more energy without deforming and the uneven inner surfaces  210  may flex or deflect more without breaking or permanently deforming. Further, the uneven inner surfaces  210  may be more likely to resiliently return to there original configurations. Thus, the serrated inner surfaces  210  of the lip  28  may form a more durable and longer-lasting outer portion of the table top  12 . 
   The lip  28  may also include one or more ribs  220  that increase the wall thickness of the inner surface  210  of the lip. Advantageously, the ribs  220  may also increase the strength, rigidity and/or flexibility of the outer portions of the table top  12 . The ribs  220  preferably extend from the lower surface  16  of the table top  12  to the lower surface  212  of the lip  28  and the ribs are preferably generally vertically aligned, but the ribs may have any suitable arrangement and configuration. It will be appreciated that the ribs  220  may be used in combination with the inwardly extending portions  216  and/or the outwardly extending portions  218  to increase the strength of the table top  12 . Further, it will be appreciated that the inwardly extending portions  216 , outwardly extending portions  218  and/or ribs  220  may be located in other suitable portions of the table top  12 , such as the outer surfaces of the lip, the edge  22  of the table top  12 , and/or the lower surface  212  of the lip. It will be understood, however, that the table top  12  does not require inwardly extending portions  216 , outwardly extending portions  218  or ribs  220  be formed in the inner surface of the lip  28 . 
   Significantly, the inwardly extending portions  216 , outwardly extending portions  218  and/or ribs  220  may be positioned such that they are generally consistent with the pattern of depressions  30  formed in the lower surface  16  of the table top  12 . That is, the inwardly extending portions  216 , outwardly extending portions  218  and/or ribs  220  may be located so that they are aligned with the pattern of depressions  30  to create a table top  12  with more uniform characteristics. This may allow a table top  12  to be constructed with generally consistent strength and structural integrity. 
   Further, as best seen in  FIG. 18 , one or more of the corners  222  of the table top  12  may have one or more inwardly extending portions  216 , outwardly extending portions  218  and/or ribs  220  to increase the strength and structural integrity of the corner. The inwardly extending portions  216 , outwardly extending portions  218  and/or ribs  220  may be spaced closer together in the corners  222  than along the inner surface  210  of the lip  28 , if desired, to further increase the strength and structural integrity of the table top. The inwardly extending portions  216 , outwardly extending portions  218  and/or ribs  220  may be particularly advantageous in the corners  222  because the corners may be more likely to be damaged and the curved surfaces of the corners may have less strength than the straight edges of the table top  12 . 
   In order to further increase the strength and structural integrity of the corners  222 , the radius of the corners may be increased because the strength and structural integrity of the corners increases with a larger radius of curvature. Preferably, the radius of curvature of the inner surface of the corner  222  is increased and one or more inwardly extending portions  216 , outwardly extending portions  218  and/or ribs  220  are formed in the corner for added strength. It will be appreciated that the inwardly extending portions  216 , outwardly extending portions  218  and/or ribs  220  may also be formed on the outer surfaces of the corners  222  and/or the other edges of the table top  12 . Other suitable embodiments for a table top with inwardly extending portions, outwardly extending portions and/or ribs are disclosed in Assignee&#39;s co-pending U.S. patent application Ser. No. 10/409,273, entitled Edge and Corner for a Table Top, which is hereby incorporated by reference in its entirety. 
   As seen in  FIGS. 2 and 3 , the inner surface  210  of lip  28  may also contain one or more handles  224  that are integrally formed in the table top  12 . The handles  224  allow the table  10  to be easily carried when the legs  62 ,  64  are in the collapsed position. In particular, the handles  224  are preferably sized and configured to allow the user to grip the table  10  with one hand and the handles are preferably located at or near the center of the table top  12 . The handles  224  are preferably integrally formed in the lip  28  of the table top  12  so that the generally consistent pattern of depressions  30  in the lower surface  16  of the table top is not disturbed, but the handles may be formed in any desired portion of the table top. Additionally, while the handles  224  are preferably integrally formed in the table top  12  as part of a one-piece blow-molded structure, the handles do not have to be integrally formed in the table top. 
   Significantly, the lip  28 , inwardly extending portions  216 , outwardly extending portions  218 , ribs  220  and handles  224  may be integrally formed in the table top  12  as part of a unitary, one-piece structure. Desirably, these features are integrally formed in the table top  12  during the blow-molding process. It will also be understood that other features of the table top  12  may be integrally formed as part of a one-piece structure. For example, the depressions  30 , frame mounting portions  36 , bracket mounting portions  110 , and clip receiving portions  184  may be integrally formed as part of the one-piece structure. Because these features may be integrally formed in the table top  12 , that may expedite the manufacturing process. These features, however, do not have to be integrally formed in the table top  12  and they could be attached to the table top by any suitable methods or devices. 
   As seen in  FIGS. 19 and 20 , the table top  12  may also be constructed from two or more pieces. In particular, the table top  12  may be constructed from a first piece  230  and a second piece  232  with one or more interlocking portions  234  and one or more overlapping portions  236  to create the table top  12  that folds in half. Significantly, the table top  12  that folds in half may allow the table  10  to be easily transported and/or stored. Additionally, the various features discussed above can be integrally formed in the table top  12  constructed from two or more pieces. It will be appreciated, however, that the table top  12  does not have to be constructed from two or more pieces. Other suitable embodiments for a table top that is foldable are disclosed in Assignee&#39;s co-pending U.S. patent application Ser. No. 10/408,914, entitled Portable Folding Table, which is hereby incorporated by reference in its entirety. 
   Although this invention has been described in terms of certain preferred embodiments, other embodiments apparent to those of ordinary skill in the art are also within the scope of this invention. Accordingly, the scope of the invention is intended to be defined only by the claims which follow.
