Description:
This application claims the benefit of Provisional Patent Application No. 60/076,398 filed Feb. 28, 1998. This application is Div. of Ser. No. 09/259,078, filed Feb. 26, 1999. 
    
    
     BACKGROUND OF THE INVENTION 
     This invention relates to adjustable shelving and, in particular, to adjustable shelving of the type in which brackets are mounted in perforated vertical supports. This shelving system also is well suited for use with means for firmly but reversibly attaching such items as bookends, signs and lamps to shelving as described in the U.S. patents to Stuart (U.S. Pat. Nos. 5,655,670, 6,044,982 and 6,119,992) which reference, in turn, U.S. Provisional Patent Applications Nos. 60/057,230; 60/061,045; and 60/064,042). 
     BRIEF DESCRIPTION OF THE PRIOR ART 
     Shelving systems, as well as display stands and showcases come in a variety of configurations and styles. Depending upon the nature of the articles to be stored or displayed, many utilize sections of shelves affixed to a supporting wall or pedestal. A very popular type of shelving system includes vertical standards having a longitudinal series of slots, so that when the standards are mounted on a vertical wall surface they may receive outwardly projecting, horizontal blade-like brackets (for example, see U.S. Pat. No. 1,983,470). The brackets are usually provided with hooks or ears to permit the brackets to be engaged in selected slots of the standards. In this way, the brackets are adapted to support shelves at selected locations and at selected distances from one another. 
     Appearance: Cantilever shelving described in the prior art is generally not attractive in appearance. Conventional brackets of the type described are often formed from sheet metal with nose portions that project beyond the front edges of the shelves to keep the shelves from sliding off the brackets. Thus, the unattractive brackets and standards are exposed. Cantilever shelving systems are therefore usually mounted in garages, recreation rooms and the like, but not in living rooms, dining rooms, retail areas and offices where the setting is more dressy. 
     Attempts have been made in the prior art to enhance the appearance of shelving systems of the general type described above. It has been proposed, for example, to embed hooks or support plates within wooden shelf brackets. Another approach involves using a standard and bracket assembly with an off-set bracket and a cover over the openings in the standard (see U.S. Pat. No. 5,277,393). This particular approach is only partially successful in that it does not improve the appearance of the bracket. These approaches also would require discarding the shelf brackets now in use, and substituting completely new brackets or equivalent shelf mounts. 
     Other systems apply a sleeve-like covering to the bracket, however, these systems have several disadvantages. First, they cover only the bracket and do not cover the standard. Second, they require that the covering be secured using, for example, shims or adhesive metal tape provided with gripping teeth or protrusions, thus requiring additional assembly by the user. Still other systems secure the covering to the bracket by cutting a groove in the decorative covering which is slightly smaller than the bracket so that the bracket is held in place by friction. This limits the size of the bracket which may be employed and may permit the bracket to become dislodged. Yet another approach involves a cumbersome decorative covering that conceals both the standard and shelf bracket (see U.S. Pat. No. 5.560,580). 
     The prior art thus has not solved the problem of easily and decoratively covering conventional shelf brackets and standards in a manner which conceals both the unattractive horizontal blade-like arms and the unattractive vertical standards. 
     Accidental Dislodgement and Side Sway: Prior art shelf assemblies often have the problem that the shelf portion of the assembly is not secured to the shelf mounting brackets, thus permitting accidental movement. Unsecured shelves may be very undesirable, for example, if objects are to be placed on the shelf without evenly distributing their weight, causing the shelf to become unbalanced. 
     Although some shelf assemblies may overcome this problem by securing the shelf to the mounting brackets excessive effort may then be required for disassembly to remove or replace a single shelf. Often a shelf needs replacement or repair because of damage or deterioration. It may also be desirable to chance the color or style of a shelf for aesthetic reasons. 
     A disadvantage of the brackets usually used for cantilever shelving is potential side to side sway. In order to limit side sway of such brackets, the brackets have previously been provided with special features such as a transverse clip as in U.S. Pat. No. 1,983,470 or use of double brackets for each standard. Prior devices have also included saddle type clips on the brackets or adhesives (see for example U.S. Pat. No. 5.069,408). However, the adhesive tends to lock the shelf in place and thus interferes with repositioning the shelf as needed for later changes in the shelving system. 
     Ease of Assembly: Many of the shelving systems described in the prior art are difficult to assemble. Shelving systems are typically provided as knock-down kits for assembly at the user&#39;s location, thus minimizing shipping costs by avoiding the need to transport bulky assemblies. Assembly of these units then becomes the task of the user, who is typically unfamiliar with the assembled design, and this requires the location and identification of a multitude of parts, and an understanding of packaged instructions concerning their assembly. The problems with this approach are based on complicated prior art designs, which do not lend themselves to quick construction. 
     In addition, it would be an advantage to provide the shelving system in a form that allowed upgrading existing shelving, thus providing greater function and enhanced appearance at low cost. 
     Wire Rod Construction: It would also be an advantage to provide the shelving system in a wire rod version. Wire shelving has long been used in institutional settings, but in recent times has gained popularity in domestic new construction and remodeling. Wire shelving has largely replaced wood and particle board in areas such as kitchen cabinets, bedroom closets and linen closets. 
     A number of shelving supports and shelving systems have been developed using wire shelving (see. for example. U.S. Pat. Nos. 4,624,376; 4,669,692; 5,355,819; 5.592,886; 5,346,077; 3,294,351: 4,603.781 and 3,993,002). However, the prior art does not meet the need for a shelving system with an improved appearance, reduced side sway and reduced accidental dislodgement. 
     Enclosures, including Doors: It is frequently desirable to provide partial or full enclosures to shelving. Such enclosures are useful in avoiding articles or items from falling off the shelves and breaking or becoming lost or misplaced. Some enclosed shelving include only enclosures of the side and rear portions of the shelving. These enclosures, while providing protection to the items on the shelves, also provides convenient access to the items. Other types of enclosures include doors which can be used as a security unit. 
     Enclosures are also useful in an office or retail setting. For example, retail stores use a variety of fixtures to display merchandise for sale. Thus some merchandise may be displayed on tables, while other merchandise may be displayed on open shelves either arranged along the walls or as a component of free standing “gondolas”. Some units provide open shelves in the top portion for displaying merchandise and a closed storage compartment in the lower half of the unit. Frequently considerations of theft and security must be taken into account and in such cases it is typical to display merchandise in a limited access enclosure. 
     Enclosures for shelving are know in the prior art (see, for example, U.S. Pat. Nos. 4,509,805; 4,318,576; and 4,148,535). However, the prior art generally uses sliding doors that fit into grooves in specially designed shelves or the enclosures are designed for free-standing rather than wall-mounted shelving. 
     One Standard Construction: It would also be an advantage to provide the shelving system as a version requiring one, rather than two or more vertical standards. Such a version would be particularly useful in a confined location, e.g., at the end of a display case. The prior art (for example, see U.S. Pat. No. 5,253,835) generally requires the use of a modified shelf bracket assembly for such shelving. 
     One Shelf Version: It would also be an advantage to provide the shelving system as a one shelf version for use when one shelf would suffice. Much of the prior art (see, for example, U.S. Pat. Nos. 4,508,301; 4,691,887; 4,934,642; 5,575,444; and 5,692,717) uses a horizontal rail for supporting a single shelf as a cantilever and thus requires an expensive continuous rail. Several other approaches are also described in the prior art (see, for example, U.S. Pat. Nos. 4,361.099; 4,010.697; and 4,685,575) but these approaches are intended for use in a recess such as a window opening, or require awkward and unsightly support rods either above or below the shelf. 
     Combination of Standards with Sheet Metal or Plastic Shelves: It would also be an advantage to provide a version of the shelving system that combines sheet metal or plastic shelving with vertical standards, thus combining much of the strength and stability of wall-mounted shelving with the low cost and light weight of plastic or sheet metal shelving. 
     The prior art describes a number of free-standing sheet metal or plastic shelving systems (see, for example, U.S. Pat. Nos. 4,138,953; 5,127,342; 5,350,073 and 5,779,070) which typically use corner posts with a series of shelves supported at spaced positions on the posts. A common basic configuration comprises four uprights supporting three or more rectangular shelves, the uprights being positioned to provide a support at each of the four corners of the shelves. However, the prior art apparently does not describe the combination of wall-mounted standards with sheet metal or plastic free-standing shelving. 
     SUMMARY OF THE INVENTION 
     It is a primary object of the present invention to provide a wall-mounted shelving system for easily, conveniently, and inexpensively storing and displaying objects, with said system being well suited for use with previously described lever clamps, clamping bookends, and screw fasteners for firmly but reversibly attaching such items as signs, lamps and bookends to the horizontal and vertical surfaces of said shelving system.

     DETAILED DESCRIPTION 
     Referring first to FIG. 1, there is shown a shelving system  4  with wall uprights, tracks or standards  8 , shelves  12 , shelf brackets  16 , side panels  20  and top-hung door or lid  28  and side-hung doors  36 . So as to not interfere with the operation of the optional shelf doors, the shelf brackets  16  are modified so that the ends of the bracket which retain the front of the shelf, i.e., the retainer portions  16 a furthest away from the standards  8 , are shaped, e.g., bent back to be parallel to the front of the shelves, so they do not protrude significantly. The side panels are held in place by fasteners  24 . Several embodiments for shown below for fastening the side panels to the shelves. If desired, the side panels can be provided as several sections that fit together at their top and/or bottom edges (not shown). The lid  28  is supported by hinge supports  32  as are the side-hung doors  36  (not shown). Several embodiments are also shown below for fastening doors and lids to the side panels or shelves. The doors also have knobs  40 . A drawer  42  and shelf  12  are provided behind the side-hung doors  36 . The drawer  42  is mounted on side mount drawer slides (not shown) connected to the side panels  20 . A previously described clamping bookend partition  44  and screw fastener partition  48  are attached to the shelves and a previously described lamp  52  is attached to the side panel  20 . For previously described items, please see the above referenced patents and the provisional and nonprovisional patent applications by Stuart. In general, the side panels and doors are usually formed to be light in weight so as to be easy to assemble and also so as to not significantly interfere with the weight-bearing function of the shelves. Also if desired. e.g., for display purposes the doors and/or side panels can be formed from transparent material such as glass or some types of plastic. In addition to providing a mounting surface for lighting signs literature dispensers, etc. and helping provide useful storage areas, the side panels also help keep goods secure from theft or damage, particularly when doors are attached to the side panels or shelves. The side panels are designed for easily installation on existing shelving and thus the side panels and other components of the shelving system can be added as an upgrade. The above components are formed of strong durable materials such as, for example, metal, wood, or plastic. 
     FIG. 2 shows a cam  64  and clamp  56  for fastening a side panel  20  to a shelf  12 . The cam arm  68  is attached to a cam  64  and a side panel  20  and the cam  64  engages the top of the shelf  12 . The cam is attached via the cam pivot pin  60  to a clamp  56  consisting of a lower leg portion  56   a , a middle connecting portion  56   b  and a upper leg portion  56   c  which is generally parallel to lower leg portion  56   a . Analogous to the clamping bookend described by Stuart (U.S. Pat. No. 5,655,670), the upper leg portion  56   c  contains an opening (not shown) that receives the cam  64 . The leg portions  56   a ,  56   c  and connecting portion  56   b  define a slot  70  that receives a shelf  12  therein. The above components are formed of strong durable materials such as, for example, wood, metal, or plastic. 
     The operation of the cam and clamp can be summarized as follows: With the side panel in the raised, disengaged, or opened position  20 ′ shown in phantom, where the cam arm is moved away from being parallel to leg portions  56   a  and  56   c , tie clamp  56  is placed on a shelf  12 . The clamp is sized such that the slot  70  is slightly larger than the thickness of the shelf and the shelf fits loosely within the slot. Once placed on the shelf, the side panel  20  is lowered by hand, whereby the cam  64  extends into slot  70  through the opening in the upper leg portion  56   c  and engages the upper surface of the shelf  12 , thereby wedging the shelf between the cam and the lower leg portion  56   a  of the clamp. The clamping force generated by the cam is sufficient to firmly maintain the side panel on the shelf without marring or otherwise damaging the shelf. The cam and clamp can be removed from the shelf by lifting the side panel to the raised or opened position  20 ′ so that the cam no longer engages the shelf. 
     As disclosed for the clamping bookend and related clamp in U.S. Pat. Nos. 5,655,670 and 6,044,982 to Stuart, it will be recognized that the clamping force can be varied to avoid damaging the shelf by changing the size or rigidity of the cam  64 . In addition, the clamping force can be increased by increasing the roughness of the cam which engages the shelf or by placing shims or pads between the cam  64  and the shelf  12  or between the lower leg portion  56   a  of the clamp and the shelf. 
     FIG. 3 shows an alternative embodiment, i.e., a clamping foot  76 , clamping foot pad  80  and clamp  56  for fastening a side panel  20  to a shelf  12 . The clamping foot  76  is attached to a side panel  20  and a clamping foot pad  80 . The clamping foot pad  80  engages the lower surface of the shelf  12 . The side panel, clamping foot and clamping foot pad are attached via a clamp hinge  72  to a clamp  56  consisting of a lower leg portion  56   a , a middle connecting portion  56   b  and a upper leg portion  56   c  which is generally parallel to leg portion  56   a . The lower leg portion  56   a  contains an opening (not show) that receives the clamping foot pad  80 . Leg portions  56   a ,  56   c  and connecting portion  56   b  define a slot  70  that receives a shelf  12  therein. The above components are formed of strong durable materials such as, for example, wood, metal, or plastic. 
     The operation of the clamping foot and clamp can be summarized as follows: With the side panel in the raised, disengaged, or opened position  20 ″ shown in phantom, where the clamping foot is moved away from being parallel to leg portions  56   a  and  56   c , the clamp  56  is placed on a shelf  12 . The clamp is sized such that the slot  70  is slightly larger than the thickness of the shelf and the shelf fits loosely within the slot. Once placed on the shelf, the side panel  20  is lowered by hand, whereby the clamping foot pad  80  extends into slot  70  through the opening in the lower leg portion  56   a  and engages the lower surface of the shelf  12 , thereby wedging the shelf between the clamping foot pad  80  and the upper leg portion  56   c  of the clamp. The clamping force generated by the clamping foot and clamping foot pad is sufficient to firmly maintain the side panel on the shelf without marring or otherwise damaging the shelf. The side panel can be removed from the shelf by lifting the side panel to the raised or open position  20 ′ so that the clamping foot pad  80  no longer engages the shelf  12 . 
     As disclosed for the clamping bookend and related clamp in U.S. Pat. No. 5,644,670 to Stuart and the U.S. patent application by Stuart Ser. No. 09/161,259, it will be recognized that the clamping force can be varied to avoid damaging the shelf by changing the size or rigidity of the clamping foot  76  and/or clamping foot pad  80 . In addition, the clamping force can be increased by increasing the roughness of the clamping foot pad which engages the shelf or by placing shims or pads between the clamping foot pad  80  and the shelf  12  or between the upper leg portion  56   c  of the clamp and the shelf. 
     FIG. 4 shows a screw fastener  84  and clamp  56  for fastening a side panel  20  to a shelf  12 . A similar clamp and screw fastener for fastening bookends, partitions or banding and/or binning to shelves or other objects were disclosed in U.S. Pat. Nos. to Stuart (6,044,982 and 6,119,992). The above components are formed of strong durable materials such as, for example wood, metal, or plastic. 
     The structure and function of the clamp  56  and screw fastener  84  can be summarized as follows: The clamp  56  includes a lower leg portion  56   a , an upper leg portion  56   c  which is generally parallel to leg portion  56   a , and a connecting portion  56   b . Leg portions  56   a ,  56   c  and connecting portion  56   b  define a slot  70  which receives a shelf  12  therein. The screw fastener  84  rotates in a threaded opening in the upper leg portion  56   c  and reversibly presses against the shelf. The clamp  56  is attached to the side panel  20  and is sized such that slot  70  is slightly larger than the thickness of the shelf and the shelf fits loosely within the slot. With the screw fastener knob  88  rotated so that the screw fastener stud  104  does not significantly protrude into the slot  70 , the clamp  56 , screw fastener  84  and side panel  20  are placed on a shelf  12 . Once placed on the shelf, the screw fastener knob  88  is rotated so that the end of the screw fastener stud  104  extends into slot  70  and engages the surface of the shelf  12 , thereby wedging the shelf between the end of the screw fastener stud  104  and the lower leg portion  56   a  of the clamp. As the screw fastener  88  is rotated, the clamp  56  is pushed against the shelf  12 , thus forming a tight fit between the shelf and the clamp and securely fastening the clamp to the shelf at a selected location. If desired, the end of the screw fastener stud  104  can be provided with a screw fastener pad (not shown) to help prevent marring of the surface of the shelf. 
     The screw fastener  84  is equipped with a previously described optional latch consisting of a rachet wheel  100 , spring  92 , and a spring mount  96  to reversibly retain said screw fastener in the tightened or operative position after rotation. The rachet wheel, spring, and spring mount are formed of a strong durable material such as metal or plastic. The rachet wheel  100  is formed as an integral component of the screw fastener knob  88 , while the spring  92  is connected to spring mount  96  which is connected to the clamp  56 . The spring  92  is oriented so that it presses against the teeth of the rachet wheel  100 . The end of the spring  92  that engages the teeth of the rachet wheel is shaped so as to allow free rotation of said rachet wheel  100 , and thus the connected screw fastener stud  104 , in the direction that moves the stud toward the shelf  12 , i.e., as the grip is increased and the clamp and side panel is installed. However, the spring  100  does not allow free rotation of the screw fastener stud  104  in the direction that moves the stud away from the shelf  12 , i.e., as the grip is reduced. Rotation in this direction is only feasible by pressing the spring  92  so as to release said spring from the teeth of said rachet wheel  100 . Since, during rotation of the screw fastener  84 , the screw fastener and the related rachet wheel  100  move relative to the spring  92 , either the rachet wheel  100  or spring  92  are formed of a large enough thickness for said rachet wheel and said spring to stay engaged during the operational length of travel of the screw fastener. The embodiment shown provides a rachet wheel  100  that is thicker than the spring  92 . 
     It will be noted that the knob  88 , rachet wheel  100  and stud  104  may be formed as one piece or unit of hard material such as metal or rigid plastic, while the spring  92  and spring mount  96  may be formed of one piece of a slightly more flexible material such as a semi-flexible plastic. 
     As disclosed for the screw fastener bookend and a related clamp in the U.S. Pat. No. by Stuart 6,119,992, the grip generated by a screw fastener  84  is sufficient to firmly maintain the bookend on the shelf without marring or otherwise damaging the shelf. It will be recognized that the grip can be varied by changing the diameter of the screw fastener knob  88  since, when the screw fastener is operated by hand, the larger the diameter of the screw fastener knob  88 , the greater the amount of force that can be provided by the knob to the screw fastener stud  104 . Also, the amount of force per each unit of surface area of the engaged surface of the shelf from the screw fastener stud  104  can be regulated by changing the diameter of the screw fastener stud  104 , since decreasing the diameter of the stud increases the amount of force per each unit of surface area of the shelf. As noted above, a screw fastener pad (not shown) can be provided on the end of the screw fastener stud to help prevent marring of the shelf surface. In addition, the grip generated by the screw fastener  84  can be increased by increasing the roughness of the end of the screw fastener stud  104  which engages the shelf. Additional means for ensuring that a screw fastener used to fasten a bookend to a shelf does not damage the shelf are disclosed in the Patent Application referenced above. 
     It will be noted that the screw fastener and clamp assembly would also be suitable for fastening the side panel  20  to lower shelves  12  so as to hold the lower portion of the side panel in place and thereby add rigidity to the shelving system. 
     FIG. 5 shows a pull rod  116  and clamp  56  with a clamping leg  128  for fastening a side panel  20  to a shelf  12 . The upper portion of the pull rod  116  is attached, via a upper pull rod pin  112  to a pull rod support  108 , which is attached to a side panel  20 . The side panel is attached to the clamp  56  by a hinge  118 . The lower portion of the pull rod is attached, via a lower pull rod pin  120 , to a leg rod  124  which is attached to the clamping leg  128 . The upper leg portion  56   c  and connecting portion  56   b  of the clamp  56 , together with the clamping leg  128  and pad  132  define a slot  70  which receives a shelf  12  therein. The pad  132  engages the lower surface of the shelf  12 . The above components are formed of strong durable materials such as, for example, wood, metal, or plastic. 
     The operation of the pull rod  116 , clamp  56  and clamping leg  128  can be summarized as follows: With the side panel in the raised, disengaged, or opened position  20 ′″ shown in phantom, the clamp  56  and clamping leg  128  are placed on a shelf  12 . The clamp and clamping leg  128  are sized such that the slot  70  is slightly larger than the thickness of the shelf and the shelf fits loosely within the slot. Once placed on the shelf, the side panel is lowered by hand, whereby the pull rod is pulled upward as the side panel rotates around the hinge  118 . As the pull rod  116  is pulled upward, it pulls the clamping leg  128  and pad  132  upward forcing the pad against the bottom of the shelf  12 , thereby wedging the shelf between the pad and the upper leg portion  56   c  of the clamp. The clamping force generated by the pull rod is sufficient to firmly maintain the side panel on the shelf without marring or otherwise damaging the shelf. The side panel can be removed from the shelf by lifting the side panel to the raised or open position  20 ′ so that the pad  132  no longer engages the shelf. 
     As disclosed for the clamping bookend and related clamp in U.S. Pat. Nos. 5,655,670 and 6,044,982 to Stuart, it will be recognized that the clamping force can be varied to avoid damaging the shelf by changing the size or rigidity of the leg  128  and/or pad  132 . In addition, the clamping force can be increased by increasing the roughness of the pad  132  which engages the shelf or by placing shims or pads between the pad  132  and the shelf  12  or between the upper leg portion  56   c  of the clamp and the shelf. 
     FIG. 6 shows the use of a butt hinge  136  to mount a door  36  to a side panel  20 . 
     In this embodiment, the door  36  opens outward and to the side. In this and the following figures showing hinges, it should be recognized that many other types of hinges could also be employed such as pivot hinges, invisible hinges, pin hinges, and concealed or European hinges. The components described above and in the following embodiments are formed of strong durable materials such as metal, wood, or plastic. 
     FIG. 7 shows a door  36  mounted to a side panel  20  using a butt hinge clamp and screw fastener assembly  140  having a clamp  56  and a screw fastener  84 . The operation of the assembly  140  is basically as described above for the clamp  56  and screw fastener  84  in FIG.  4 . As in FIG. 6, the door in this embodiment opens outward and to the side. 
     FIG. 8 shows a top-hung door or lid  28  fastened near its top edge to a side panel  20  using a butt hinge  136 . In this embodiment, the lid would open upward and would usually be equipped with a lid stay (not shown) to hold the lid in the raised or open position as desired. The lid  28  could also be fastened near its bottom edge to the side panels  20  using a butt hinge so that the lid opened from its top and the top edge would open out and down. In this case, a lid support would usually be provided to keep the lid from dropping too far when opened. 
     FIG. 9 shows a door  36  mounted to a side panel  20  using a butt hinge clamp and lever fastener assembly  144  having a clamp  56  and a lever fastener  148 . As in FIGS. 6 and 7, the door would open outward and to the side. 
     The operation of the lever fastener  148  is very similar to the operation of the clamping bookend and related clamp disclosed in U.S. Pat. Nos. 5.655,670 and 6,044,982 to Stuart. The clamping member  152  is attached via the clamping member pivot pin  156  to a clamp  56  consisting of a lower leg portion  56   a , a middle connecting portion  56   b  and a upper leg portion  56   c  which is generally parallel to leg portion  56   a . The leg portions  56   a ,  56   c  and connecting portion  56   b  define a slot  70  that receives a side panel  20  therein. The clamp  56  is attached to a hinge which is attached to the door  36 . The above components are formed of strong durable materials such as, for example, wood, metal, or plastic. 
     The operation of the clamping member and clamp can be summarized as follows: With the clamping member  152  in the lowered, disengaged, or opened position, where the clamping member is nearly parallel to leg portions  56   a  and  56   c , the clamp  56  is placed on the side panel  20 . The clamp is sized such that the slot  70  is slightly larger than the thickness of the side panel and the side panel fits loosely within the slot. Once placed on the side panel, the clamping member  152  is raised by hand, whereby the clamping member  152  extends into slot  70  and engages the surface of the side panel  20 , thereby wedging the side panel between the clamping member and the lower leg portion  56   a  of the clamp. The clamping force generated by the clamping member is sufficient to firmly maintain the clamp on the side panel without marring or otherwise damaging the side panel. The clamping member  152  is held in the locked upright position by the previously described pin latch  160 . The clamping member  152  contains a recessed area to allow the insertion of an extension lever that can be used to more easily move the clamping member from the open to the engaged position. The clamping member and clamp can be removed from the side panel by moving the clamping member to the lowered or opened position so that the clamping member  152  no longer engages the side panel  20 . 
     As disclosed for the clamping bookend and related clamp in U.S. Pat. Nos. 5,655,670 and 6,044,982 to Stuart, it will be recognized that the clamping force can be varied to avoid damaging the side panel by changing the size or rigidity of the clamping member  152 . In addition, the clamping force can be increased by increasing the roughness of the clamping member which engages the side panel or by placing shims or pads between the clamping member  152  and the side panel  20  or between the lower leg portion  56   a  of the clamp and the side panel  20 . 
     It will be noted that, like the screw fastener  84  and clamp  56  discussed above, the lever fastener  148  and clamp  56  could also be used to fasten the lower portion of a side panel  20  to a lower shelf so as to add rigidity to the shelving system. 
     FIG. 10 shows a door or lid  28  fastened near its top edge to a shelf  12  using a butt hinge clamp and screw fastener assembly  140  having a clamp  56  and a screw fastener  84 . The operation of the assembly  140  is basically as described above for the screw fastener  84  and clamp  56  in FIG.  4 . In this embodiment, the lid would open outward and upward and would usually be equipped with a lid stay (not shown) to hold the lid in the raised or open position as desired. 
     FIG. 11 shows a lid  28  fastened near its top edge to a shelf  12  using a butt hinge clamp and lever fastener assembly  144  having a clamp  56  and a lever fastener  148 . The operation of the assembly  144  is basically as described above for the clamp  56  and lever fastener  148  in FIG.  9 . In this embodiment, the lid would open outward and upward and would usually be equipped with a lid stay (not shown) to hold the lid in the raised or open position as desired. 
     FIG. 12 shows a lid  28  fastened near its top edge to a shelf  12  using a butt hinge  136 . In this embodiment, the lid would open outward and upward and would usually be equipped with a lid stay (not shown) to hold the lid in the raised or open position as desired. 
     FIG. 13 shows a lid  28  fastened at its bottom edge to a shelf  12  using a butt hinge  136 . In this embodiment, the lid would open outward and down. A lid support (not shown) would usually be provided to keep the lid from dropping too far when opened. 
     FIG. 14 shows a shelving system similar to that in FIG. 1, except that this system has been designed for use in a commercial setting, e.g. a retail store. The system includes the components shown in FIG. 1 but also is suitable for use with shelving accessories such as banding supported by clamping members  164 , banding supported by screw fasteners  174 , binning  176 , a sign holder with a clamp  170 , a literature dispenser with a clamp  172 , and a banding strip  178 . The construction and operation of these and other shelving accessories was disclosed in a U.S. patents to Stuart (U.S. Pat. Nos. 5,655,670; 6,044,982; and 6,119,992). In general, the side panels and doors are formed to be light in weight so as to be easy to assemble and so as to not significantly interfere with the weight-bearing function of the shelves. Also, if desired. e.g., for display purposes, the doors, side panels or other components can be made from transparent material such as glass or some types of plastic. It will be noted that some of the commercial modifications, e.g., slanted display shelves, are also suitable for domestic applications. The above components are formed of strong durable materials such as, for example, metal, wood, or plastic. 
     FIG. 15 shows the slanted shelf bracket  180  for supporting slanted display shelves  168 . The slanted bracket arm  182  is attached to a bracket base  184  which attaches to an standard  8  by means of typical shelf bracket mounting hooks or ears (not shown). An optional brace  186  is also provided to provide additional support, as is an additional optional cross-brace  188  that helps keep the brace in line with the bracket arm  182  and the standard  8 . 
     It can be seen that the shelving system shown in FIGS. 1-15,  27 - 38 ,  61  and  64  presents an improved appearance over the prior art, since the unsightly standards and brackets are generally masked from view by the side panels. It can also be seen that the side panels provide additional stability and thus guard against accidental dislodgement and side to side sway. This shelving system also provides a wire rod version, a one standard version and a one-shelf version as well as enclosures for use in storage and security. Finally, this shelving system can be easily assembled and can be provided as an upgrade for existing shelving. 
     FIG. 16 shows a previously described banding strip  178  installed at the lower edge of a slanted display shelf  168  to organize objects on said shelf. The banding strip consists of a banding strip body  190  attached to a clamp  56  with a screw fastener  84 . The operation of the screw fastener  84  and clamp  56  is basically as described above for the screw fastener  84  and clamp  56  in FIG.  4 . 
     In addition to the approach show above of supporting shelves  12  with brackets  16  positioned along the length of the shelf, it is also feasible to support wall-mounted shelves by truncated side panel brackets or end brackets  194 , which also can serve additional purposes such as supporting book stops. etc. 
     FIG. 17 shows an end bracket  194  supporting the end of a shelf  12 . The basic end bracket  194  consists of a base  200 , that connects to the standard  8  by means of typical shelf bracket mounting hooks or ears (not shown), and also connects to an end bracket support  198  which, in turn, is attached to the end bracket channel  196 . The end bracket channel consists of a lower leg portion  196   a , a middle connecting portion  196   b  and upper leg portion  196   c  which is generally parallel to leg portion  196   a . Leg portions  196   a ,  196   c  and connecting portion  196   b  define a channel slot  202  that receives a shelf  12  therein. An optional indented portion  196   d  of the end bracket channel protrudes from the upper leg portion of the channel  196  into the slot  202  and, when the shelf is inserted into the channel by hand, the indented portion presses against the surface of the shelf, and thus helps keep the shelf in position. 
     FIG. 18 shows a similar embodiment except that a book stop support  208  and book stop  204  are attached to the end bracket channel  196 . The book stop is used to help organized objects such as books on the shelf, In this embodiment, the optional indented portion  196   d  of the end bracket channel protrudes from the bottom leg portion of the end bracket channel into the slot  202  (not shown). 
     FIG. 19 shows an alternative embodiment of the end bracket channel  196  for keeping the shelf in position, where the base  200  and end bracket support are connected to a end bracket channel  196  with a clamping member  152  and a book stop  204 . The end bracket channel consists of a lower leg portion  196   a , a middle connecting portion  196   b  and upper leg portion  196   c  which is generally parallel to leg portion  196   a . Leg portions  196   a ,  196   c  and connecting portion  196   b  define a channel slot  202  for receiving a shelf  12  therein. The upper leg portion  196   c  contains a cut-out  206  within which the clamping member  152  is connected with said upper leg portion  196   c  by a pivot pin  156 . In this embodiment the clamping member  152  wedges the shelf between the clamping member and the lower leg portion  196   a  of the end bracket channel  196 . A similar clamping member is described above for FIG.  9 . The above components are formed of strong durable materials such as, for example, wood, metal, or plastic. 
     The operation of the clamping member and channel can be summarized as follows: With the clamping member  152  in the lowered, disengaged, or opened position, where the clamping member is nearly parallel to leg portions  196   a  and  196   c , the shelf is placed in the channel  196 . The channel is sized such that the channel slot  202  is slightly larger than the thickness of the shelf and the shelf fits loosely within the slot. Once the shelf is placed in the channel, the clamping member  152  is raised by hand, whereby the clamping member  152  extends into slot  202  and engages the surface of the shelf  12 , thereby wedging the shelf between the clamping member and the lower leg portion  196   a  of the end bracket channel  196 . The clamping force generated by the clamping member is sufficient to firmly maintain the clamp on the shelf without marring or otherwise damaging the shelf. The clamping member  152  supports a book stop  204  to help organize objects on the shelf. The shelf may be removed from the channel by moving the clamping member to the lowered or opened position so that the clamping member  152  no longer engages the shelf  12 . 
     As disclosed for the clamping bookend and related clamp in U.S. Pat. Nos. 5,655,670 and 6,044,982 to Stuart, it will be recognized that the clamping force can be varied to avoid damaging the shelf by changing the size or rigidity of the clamping member  152 . In addition, the clamping force can be increased by increasing the roughness of the clamping member which engages the shelf or by placing shims or pads between the clamping member  152  and the shelf  12  or between the lower leg portion  196   a  of the clamp and the shelf. 
     Note that FIGS. 17 and 19 also show the use of a short standard  8  and end brackets  194  to provide an easily installed and easily removed single shelf. 
     FIG. 20 shows an alternative embodiment in which the shelf is held in place by an end bracket with a clamping member  152  with a clamping foot portion  152   a  and a set screw latch mechanism  214 , with the slot  202  for the shelf defined by the clamping member  152  and the upper leg portion  196   c  and connecting portion  196   b  of the end bracket channel  196 . A book stop  204  is provided at the upper end of the clamping member  152 . The shelf is installed by placing the upper surface of the shelf  12  against the upper arm  196   c , with the shelf pressed against the connecting portion  196   b . The clamping foot portion  152   a  is then pressed against the shelf by direct pressure or by rotating the clamping member via the pivot pin  156 . Once the clamping foot portion  152   a  is pressed tightly against the shelf, the set screw  214  is tightened to hold the clamping member in the clamped position. The clamping foot portion  152   a  concentrates the pressure exerted by the clamping member and thus helps provide a firm grip. A similar clamping member and set screw latch was described earlier in a U.S. Pat. No. 6,044,982. 
     FIG. 21 shows an alternative embodiment with a screw fastener  84  used to hold the shelf in the end bracket channel  196 . The structure and function of the screw fastener  84  and end bracket channel  196  is basically as described above for the screw fastener  84  and clamp  56  in FIG.  4 . 
     FIG. 22 shows an alternative embodiment with a screw fastener  84  as in FIG. 21 but with the addition of a book stop  204 , retaining member  218  and a retaining member extension  218   a  that extends between the upper leg  196   c  of the end bracket channel  196  and the stud of the screw fastener  104  (not shown). The use of a screw fastener and a retaining member and retaining member extension were described in a U.S. Pat. No. 6,119,992 by Stuart. 
     FIG. 23 shows a shelving system with many of the same components of the shelving system of FIG. 14 except that side panel brackets  210  connect directly to the standards  8 . This embodiment increases the over-all rigidity and strength of the system, provides a cleaner look and, in comparison to a system using side panels, reduces costs and assembly time since fewer components are needed. Unlike conventional shelving systems or a system employing side panels, this embodiment also reduces side to side sway since the shelves can be directly in contact with the supporting wall. This embodiment can be provided as an upgrade to existing shelving and standards, however, the standards in an existing installation would most likely need to be moved further apart so that the existing shelving would fit in the distance between the newly installed side panel brackets. A new standard  8  with one or more shelf brackets and/or slanted shelf brackets can also be installed if additional support is desired. As shown in FIG. 23, in this embodiment of a shelving system, the shelving system no longer uses fasteners  24  for attaching the side panels to the shelves  12  or shelf brackets  16  and/or slanted shelf brackets  180  for supporting the shelves. Instead, the shelves are supported directly by the side panel brackets  210 . 
     As shown in FIG. 24, the side panel brackets  210  connect to the standards  8  using typical shelf bracket mounting ears  192 . To provide an even cleaner look and also help reduce side to side sway, the side panel brackets  210  may be formed with recessed mounting ears  192  so as to fit completely over the standards  8  and thus hide the standards from view (see below). 
     FIGS. 25 and 26 show two embodiments for supporting the shelves by the side panel brackets  210 . In FIG. 25, the shelf  12  is supported by an opening or groove  212  in the side panel bracket  210 , while in FIG. 26, the shelf  12  is supported using a support rod  216 . Additional approaches (not shown) include the use of brackets or flat spoons that fit into holes in the side panel bracket, as well as the use of the Swedish type of wire shelf support (where the center portion of the wire fits into a groove in the shelf and the ends of the wire fit into holes in the side panel bracket) or the use of shelf support strips or standards and brackets. Of course, if additional rigidity and strength are desired, the shelves could be fastened directly to the side panels using strong adhesive or mechanical means such as screws. 
     It can be seen that the shelving system shown in FIGS. 17-26,  39 - 40 ,  55 - 58 ,  60 ,  62  and  63  presents a further improved appearance over the prior art, since the unsightly brackets are no longer used and the standard can be fully masked by the side panel bracket. Also, the use of side panel brackets further reduces the likelihood of accidental dislodgement, since the ends of the shelves are sheltered from accidental contact and can be held in place by the side panel brackets. Also, several additional approaches are available with this embodiment to reduce side to side sway even further, including placing the shelves directly against the supporting wall and providing side panel brackets with recessed ears and/or anti-sway portions. As compared to the side panel system, the side panel bracket system is also easier to assemble since there are fewer components. As with the side panel system described above, the side panel bracket system includes a wire rod version, a one standard version and a one-shelf version, enclosures for use in storage and security, and, in addition, a combination of vertical standards and sheet metal or plastic shelves. Finally, this shelving system can also be provided as an upgrade for existing shelving. 
     In addition to solid shelving as shown above, wire is often used for shelving, both in domestic and commercial applications. FIG. 27 shows a embodiment of the shelving system made from wire. In this embodiment, wire shelves  224  are supported by shelf brackets  16  and standards  8 . For some applications, wire side panels  228  are attached to the ends of the wire shelves  224 . As with nonwire shelving, in addition to providing a mounting surface for lighting, signs, literature dispensers, etc. the side panels also help keep goods secure from theft or damage, particularly if doors (not shown) are attached to the side panels or shelves. A lamp assembly  232  with a screw fastener  84  and clamp  56  is attached to the side panel, while a clamping partition assembly  240  and a screw faster partition assembly  236  are shown attached to the wire shelves  224 . The lamp assembly and partition assemblies were disclosed in a U.S. Pat. Nos. to Stuart (5,655,670, 6,044,982 and 6,119,992). The above components are formed of strong and durable materials such as metal, wood or plastic. 
     FIG. 28 shows the favored embodiment for attaching the wire side panels  228  to the wire shelves  224 . In this embodiment, the wire side panels  228  are attached to the wire shelf  224  by means of hangers  244 , preferably formed from the end of the cross wires  276  of the wire side panel. The hangers  244  fit over the support wires  222  at the end of the wire shelf  224  and thus support the wire side panel  228 . Hangers are favored over the other embodiments shown below due to the less likelihood of damage due to snagging of clothing and similar items. 
     FIG. 29 shows another embodiment, in which the wire side panels  228  are attached to the wire shelf  224  by means of individual wire hooks  248 , preferably formed from the end of the cross wires  276  of the wire side panel  228 . The hooks fit over the support wires  222  at the end of the wire shelf  224  and thus support the wire side panel  228 . 
     Yet another embodiment is shown in FIG. 30, in which the wire side panels  228  are attached to the wire shelf  224  by means of separate wire links  252 , preferably linking the support wires  272  at the end of the wire side panel  228  with the support wires  222  at the end of the wire shelf  224 . 
     An embodiment with side panels  20  attached to the wire shelves  224  is shown in FIG.  31 . In this embodiment, the side panels  20  are attached to the wire shelf  224  by means of a clip  256 , preferably linking the side panel to the support wire  222  at the end of the wire shelf  224 . The clip is attached to the side panel  20  using screws, strong adhesive, or similar means. 
     Yet another embodiment of side panels  20  attached to wire shelves  224  is shown in FIG.  32 . In this embodiment, the side panel  20  is attached to the wire shelf  224  by means of a groove  260  in the side panel. The support wire  222  and the end of the wire shelf  224  fit into the groove  260  and the groove has a lip  262  that hooks over the support wire  222  and thus holds the side panel  20  on the end of the wire shelf  224 . 
     In addition to the embodiments described above in which side panels  20  or wire side panels  228  are supported by the wire shelf  224 , separate wire shelves can also be supported by side panels  20 , wire side panels  228 , or side panel brackets  210 . FIG. 33 shows the favored embodiment for supporting a separate wire shelf  224  with wire side panels  228 , with a separate wire shelf  224  fastened to the wire side panel  228  by means of hangers  244 , preferably formed from the ends of the cross wires  226  of the wire shelf  224  and fitting over the support wires  272  of the wire side panel  228 . 
     FIG. 34 shows another embodiment, with a separate wire shelf  224  fastened to the wire side panel  228  by means of separate hooks  248 , preferably formed from the ends of the cross wires  226  of the wire shelf  224  and hooking over the support wires  272  of the wire side panel  228 . 
     FIG. 35 shows yet another embodiment, with a separate wire shelf  224  fastened to the wire side panel  228  by means of separate wire links  252 , preferably linking the support wire  222  at the end of the wire shelf  244  with the support wire  272  of the wire side panel  228 .

     FIGS. 55-58 show various embodiments of a shelving system substantially combining the elements of wall shelving using standards and shelf brackets and free-standing sheet metal shelving. Such a combination provides much of the strength and stability of wall-mounted shelving with the low cost and light weight of sheet metal shelving. Also, the system is more attractive than conventional shelving, since the metal shelf bracket is masked by the shelf. FIG. 55 shows a front view of a shelf bracket  16  supporting a sheet metal shelf  296 , with the blade portion  16   c  of the shelf bracket  16  inserted into the sheet metal shelf  296  such that the blade portion is underneath the sheet metal body portion  296   a , beside the sheet metal shelf edge bend portion  296   b  and inside the edge bend curl portion  296   c . This embodiment could also be constructed using plastic shelving rather than sheet metal shelving. As with the use of sheet metal shelving, combining the elements of wall-mounted shelving using standards and brackets with free-standing plastic shelving would provide much of the strength and stability of wall-mounted shelving with the low cost and light weight of plastic shelving. The above components are formed of strong durable materials such as metal, wood or plastic. 
     FIG. 56 shows the use of wall standards  8  and shelf brackets  16  to support the rear corners of a set of sheet metal shelves  296 , with the front of the sheet metal shelves supported by the typical metal legs  300  used to support sheet metal shelves. 
     FIG. 57 shows another embodiments, with wall standards  8  and shelf brackets  16  supporting the rear corners of sheet metal shelves  296 , with the front of the sheet metal shelves provided with partial metal legs or supports  312  that, while they do not support the weight of the shelves, help provide rigidity and keep the front of the sheet metal shelves  296  in alignment. 
     FIG. 58 shows yet another embodiment, with wall standards  8  and shelf brackets  16  supporting the rear corners of sheet metal shelves  296 . In this embodiment, the omission of the front legs and supports provides a cleaner look and improved access to the shelves but with some reduction in rigidity and strength. FIG. 58 also shows a partition assembly with a clamping member for a sheet metal shelf  316 , a partition assembly with a screw fastener for sheet metal shelving  320 , and a lamp assembly with a clamping member for sheet metal shelving  324 . These partition and lamp assemblies have been previously described in a U.S. Pat. No. to Stuart (5,655,670) and U.S. patent applications by Stuart Ser. Nos. 09/137,891 and 09/161,259. 
     FIG. 59 shows a front view of a shelf installation guide  308  with a guide body  336 , a bubble level  340 , a right angle portion  308   a  and one or two optional clips  352 . The guide is used to help ensure that the shelving standards  8  are installed correctly with the length of the guide body  336  preferably equal to the desired distance between the standards  8  of the to be installed shelving system. The bubble level  340  indicates when the guide body is in the horizontal position and the right angle portion  308   a  shows the upright position, i.e., perpendicular to the horizontal position. The optional clips  352  connect to the guide body  336  and grip the shelf standards  8  to help hold the guide and/or the standards in position for installing the standards  8  on the wall. The above components are formed of strong durable materials such as metal, wood or plastic. An inexpensive version of the guide  308  could be provided to consumers as a part of the shelving system. 
     The operation of the guide is as follows: First, the top of a standard  8  is loosely attached to the wall at the location of one of the upper-most corners of the desired shelving installation. The end of the shelf installation guide  308  having the right angle portion  308   a  is then held against the lower portion of the standard  8  and used to determine, using the level  340 , when the standard  8  is in the perpendicular position. Once the perpendicular position is determined, the top and bottom of the standard  8  is attached to the wall at this position. To add the next standard for the shelving installation, one end of the guide (with or without the optional clip  352 ) would be held against the top of the first standard and, with the level showing a horizontal position, the wall would be marked at the other end of the guide  308  to show the needed location of the top of the next wall standard  8 . The top of this next standard  8  would be loosely attached to the wall at the marked location and then the guide would be used to position the bottom of this added standard in the perpendicular position. This position would also be marked and the second standard attached to the wall at the desired positions for the top and bottom of the standard. The guide  308  would also be used to check the position of the standards prior to completing the installation of the shelving system by placing the guide at the level position, as indicated by the level  340 , at various locations between the standards  8  and checking that the standards are the correct distance apart, i.e., the distance is the same as the length of the guide body  336 . 
     In addition to shelving requiring two or more standards, shelving can also be supported by one standard. For example, FIG. 60 shows a shelving system consisting of one side panel bracket  210  attached to a standard  8  and supporting shelves  12  and other items. The embodiment shown provides a number of provisions for commercial use. As shown in the figure, the side panel bracket can support various types of surfaces and hardware suitable for use in the display and storage of merchandise, including ordinary shelves  12  and slanted display shelves  168 . These shelves are either directly attached to the side panel or supported by shelf brackets  16  or slanted shelf brackets  180  and standards  8  attached to the side panel bracket  210 . Other surfaces and hardware suitable for use in the display and storage of merchandise includes the use of pegboard  372  and pegboard hardware  376 , slatwall  364  and slatwall hardware  368 , a wire basket  356  and a storage cabinet  360  with a side-hung door  36  and knob  40 . The above components are formed of strong and durable materials such as metal, wood or plastic. 
     FIG. 60 also shows a number of items previously discussed in FIG. 14, including a sign holder  170 , lamp  52 , screw fastener partition  48 , clamping bookend partition  44 , banding supported by a clamping member  164 , a banding strip  178 , binning  176 , and a literature dispenser  172 . 
     FIG. 61 shows another shelving system which uses one standard  8  but does not use a side panel bracket  210 . In this system, which would be useful for displaying merchandise, the individual shelves are supported by one standard  8  which supports shelf brackets  384  and slanted display shelf brackets  388  designed to attach to the shelves. These shelf bracket could be attached to the shelves using a strong adhesive or could be fastened using screws or similar mechanical means. FIG. 61 shows several different types of shelves that could be used with this system, including ordinary shelving  12 , rounded shelving  386  and slanted display shelving  168 . Optional spacers  380  are provided to prevent any rotation of the shelf around the standard&#39;s vertical axis. Said spacers could be mounted to the edge of the shelf using an adhesive or fasteners such as screws. Several previously described items useful in organizing items on a shelf are also shown, i.e., banding supported by clamping members  164  and a clamping bookend partition  44 . It will be noted that additional items used to organize shelves, e.g., the screw fastener partition  48 , banding strip  178 , and binning  176  shown above in FIG. 60, would also be suitable for use in the shelving system shown in FIG.  61 . The above components are formed of strong durable materials such as metal, wood or plastic. 
     FIG. 62 shows a side panel bracket  210  with recessed mounting ears  192 . As noted above, this embodiment, in addition to providing a cleaner look, also reduces side to side sway since the shoulder portions  210   a  and  210   b  contact the supporting wall  390  and thus help lock the side panel bracket in place. This embodiment can, of course, be used with shelving requiring one, two, or more standards. 
     FIG. 63 shows a side panel bracket  210  with an anti-sway brace portion  210   c  that reduces side to side sway. Said anti-sway brace portion could be located on either side of the side panel bracket (for example, said brace portion could be located on the interior side of two side panel brackets used together as the sides of a shelving assembly). Side panel brackets with anti-sway brace portions would be used in pairs to prevent sway with one of the pair preventing sway in one direction, e.g., to the right, and the other of the pair preventing movement in the opposite direction, e.g., to the left. 
     FIG. 64 shows a shelf  12  having spacers  380  and supported by standards  8  and shelf brackets  16 . As noted above, said spacers could be mounted to the edge of the shelf using an adhesive or fasteners such as screws. As in FIG. 61, said spacers prevent rotation around the vertical axis of the standards and thus prevent side to side sway. 
     In accordance with the provisions of the Patent Statutes the preferred forms and embodiments of the invention have been illustrated and described, it will be apparent to those of ordinary skill in the art that various changes and modifications may be made without deviating from the inventive concept set forth above.
