Description:
TECHNICAL FIELD 
     The present invention relates generally to floating devices, and more particularly to an ensemble of singular construction comprising a table and a plurality of seating means attached thereto that is sufficiently buoyant to float when disposed in a body of water. 
     BACKGROUND 
     Swimming pools and other bodies of water have been used for recreational purposes since the earliest of times. In order to enhance the bathing experience, various and sundry water toys such as floating basketball hoops, balls and other items have been devised. 
     One class of recreational item commonly used in association with swimming pools is a floating chair and floating rafts. Typically, such devices accommodate a single user, who sits in the chair or raft and relaxes, usually in the sun, while in contact with the water in the pool to take advantage of its cooling effect for providing refreshment. Often, such devices include accessory features such as cup holders, so that a person residing within such a floating chair may enjoy their favorite beverage in order to enhance the pleasure of the experience. 
     Some have found a floating but stable table structure, such as a table to be a desirable item for use in a swimming pool. The device described in U.S. Pat. No. 6,171,160 provides a table of sufficient sturdiness such that even when floating it will support a drink without spillage, owing to its primary feature of a stabilizing weight which is suspended beneath the table when in use. 
     Another device useful in enhancing the experience of bathing is described in U.S. Pat. No. 19,593 which teaches a plurality of life-preserving mattress tied together by belt-and-buckle strapping to form a raft. U.S. Pat. No. 4,894,033 teaches a structure including several inflatable rafts connected together by “T” and ring or loop interconnector devices. A floating chair made up of individual rigid sections but having flexible straps permanently interconnecting the sections is provided by U.S. Pat. No. 5,176,554. U.S. Pat. No. 5,411,425 teaches a floating structure having utility as a watercraft float which includes a pair of floating pillows interconnected by a seat, with connections being made only at the four corners of the pillows and seat. U.S. Pat.

Disposed on the ends of the linear frame members which curve upwardly from the plane of the framework comprised of the linear frame members and the hollow structural conduits are flanges at  27  which in one form of the invention serve as a convenient connection means for the seating means  21 . The flange at  27  may be simply a plate of metal attached to the second end portion of the linear frame member, to which a seating means may be conveniently attached to the ensemble  69  as a whole using conventional fastening means, as the attachment of seating means to metal plates is well known in the art. The seating means  21  may be a flat piece of wood, metal, or plastic, or may comprise a cushioned seat, filled with foam or other soft materials, as are known in the art. The size of the seating means is not critical, and the main requirement is that it should be of sufficient area to accommodate the seating size requirements of most people. There is also shown the vertical support  12  having its first end portion connected to the planar framework at the common centerpoint about which the first, second, third, and fourth linear frame members are radially disposed. The vertical support  12  extends upwardly from the plane of the planar framework which is comprised of the linear frame members and the hollow structural conduits.

For added strength, braces  86  are connectively attached to the vertical support  12  and each of the hollow structural conduits. 
     In FIG. 3 is shown an overhead view of the framework portion of a table and seat ensemble  69  according to one form of the invention. In this figure are shown the various linear frame members  14   a ,  14   b ,  14   c ,  14   d , and the various hollow structural conduits  16   a ,  16   b ,  16   c , and  16   d , as well as the intersection point  20  of the first end portions of the linear frame members and the mounting points  27  for the flanges where the seating means are preferably mounted. The first hollow structural conduit  16   a  and the first and second linear frame members  14   a  and  14   b  define the outer perimeter of a first planar footspace,  99   a  within the same plane as the planar framework. Further, the second hollow structural conduit  16   b  and the second and third linear frame members  14   b  and  14   c  define the outer perimeter of a second planar footspace  99   b . Further the third hollow structural conduit  16   c  and the third and fourth linear frame members  14   c  and  14   d  define the outer perimeter of a third planar footspace  99   c . Further, the fourth hollow structural conduit  16   d  and the fourth and first linear frame members  14   d  and  14   a  define the outer perimeter of a fourth planar footspace  99   d . These footspaces are the locations where a person sitting on the ensemble  69  of the invention may rest their feet, by virtue of each of the planar footspaces each including a floor portion means  34  connected to the hollow structural conduit and linear frame members which define the respective footspaces. According to one preferred form of the invention, the floor portion means is non-metallic. Preferably, the floor portion means is made from a woven polymer, such as woven nylon, PVC, or polyolefin and is attached to the framework by conventional means such as adhesives or being woven to tied to one or more holes in the framework elements. 
     In FIG. 4 is shown a is an overhead view of the framework portion of a table and seat ensemble  69  according to one preferred form of the invention, including the seating means  21  mounted at  27 . There is also shown the first, second, third, and fourth linear frame members  14   a ,  14   b ,  14   c ,  14   d , with their first end portions intersecting at  20 . Also shown are the first, second, third, and fourth hollow structural conduits  16   a ,  16   b ,  16   c , and  16   d.    
     In FIG. 5 is shown a is a see-through overhead view of the framework portion of a table and seat ensemble  69  according to one preferred form of the invention, including the seating means  21  mounted at  27 . There is also shown the first, second, third, and fourth linear frame members  14   a ,  14   b ,  14   c ,  14   d , with their first end portions intersecting at  20 . Also shown are the first, second, third, and fourth hollow structural conduits  16   a ,  16   b ,  16   c , and  16   d . In this figure, the arrows indicate the possible motion of water within the interior spaces of the linear frame members and hollow structural conduits, which water is admitted into such interior spaces by virtue of the presence of an opening between the space enclosed by the interior portions of the hollow structural conduits and the linear frame members, and the space external them. Preferably, the hole is disposed beneath the intersection point  20 , at location shown as  25  in FIG.  6 . According to one preferred form of the invention, there are openings  23  disposed at or near the seating means mounting point  27  of each of the linear frame members, to facilitate the entry of water into the cavernous interior spaces of the linear frame members and hollow structural conduits, for in the absence of such openings air would otherwise be entrained in the space where the second end portions of the linear frame members curve upwardly and would preclude the flow of water therein. By enabling admittance of water into the device as provided by such a construct, advantageous buoyancy of the ensemble  69  of the invention as a whole is provided. 
     FIG. 6 shows a see-through side perspective view of a floating table and seat ensemble  69  according to one preferred form of the invention, showing the respective positions of the second linear frame member  14   b , fourth linear frame member  14   d , second hollow structural conduit  16   b , and third hollow structural conduit  16   c . Disposed on the ends of the linear frame members which curve upwardly from the plane of the framework comprised of the linear frame members and the hollow structural conduits are flanges at  27  which in one form of the invention serve as a convenient connection means for the seating means  21 . There is also shown the vertical support  12  having its first end portion connected to the planar framework at the common centerpoint about which the first, second, third, and fourth linear frame members are radially disposed. The vertical support  12  extends upwardly from the plane of the planar framework which is comprised of the linear frame members and the hollow structural conduits. There is a buoyant tabletop  10  having a planar top surface disposed at the second end portion of the vertical support beam. For added strength, braces  86  are connectively attached to the vertical support  12  and each of the hollow structural conduits. In FIG. 6 is also shown the flow of water through the various structural elements of the ensemble  69  including the linear frame members, the hollow structural conduits, and the vertical support  12 . When an ensemble  69  according to the invention is placed in a body of water, water is admitted into the interior volume defined by these structural elements through the hole at  25  which is located on the underside of the framework as a whole, at the intersection point  20  of the first end portions of the linear frame members. According to one form of the invention, the vertical support  12  has an opening at its second end. According to another form of the invention, the vertical support  12  includes a hole  77  disposed along its length, for the purpose of facilitating entry of water into the space within the vertical support  12 . Also shown in FIG. 6 is the vertical support guide  31 , which may be a bore, sleeve, or channel which is contoured identically to the second end portion of the vertical support  12 , but is of a slightly larger inner dimension to accommodate the insertion of the second end portion of the vertical support  12  therein to provide an interference fit between the vertical support and the tabletop  10 . In one form of the invention, the vertical support  12  is square in cross section, and the vertical support guide  31  is a square shaped tube of slightly larger dimension than the vertical support  12 . In another form of the invention, the vertical support  12  is round in cross section, and the vertical support guide  31  is a round tube of slightly larger dimension than the vertical support  12 . The vertical support guide may be an integral part of the tabletop portion  10 , or it may be a separate article of manufacture attached to the tabletop portion by any conventional means, such as welding or conventional fasteners such as screws, nuts and bolts, or rivets, etc. 
     FIG. 7 a  shows a side view of a buoyant tabletop portion  10  of an ensemble  69  according to one preferred form of the invention. In this figure is seen the vertical support guide  31  centrally disposed within the tabletop portion.

Also shown are cutout portions  88 , useful for containing a beverage container such as a glass or soda pop can. Such cutout portions  88  are holes or voids. 
     FIG. 8 b  shows an overhead view of a buoyant tabletop portion  10  of an ensemble  69  according to one preferred form of the invention. In this figure is seen the vertical support guide  31  centrally disposed within the tabletop portion. Also shown are cutout portions  88 , useful for containing a beverage container such as a glass or soda pop can. 
     FIG. 9 shows an overhead view of a buoyant tabletop portion  10  of an ensemble  69  according to one preferred form of the invention. In this figure is seen the vertical support guide  31  centrally disposed within the tabletop portion. Also shown are cutout portions  88 , useful for containing a beverage container such as a glass or soda pop can. 
     The main structural elements of the present invention include the linear frame members  14   a ,  14   b ,  14   c ,  14   d , the hollow structural conduits  16   a ,  16   b ,  16   c ,  16   d , and the vertical support  12 . According to one preferred form of the invention, these elements each contain a hollow interior space. This is readily provided for by selecting the materials from which they are fabricated from a tubular stock. In the simplest case, the aforesaid structural elements are made from tubing, such as metal pipes, or PVC tubing. PVC plastic is particularly preferred because of its relatively low weight, inertness, and strength. However, metallic tubing may be selected as the material from which these structural elements are comprised, such as aluminum, galvanized steel, or stainless steel tubing. These structural elements are connected to one another using conventional means, such as by welding when they are comprised of a metallic material which can be welded. In the case when PVC or other polymeric material comprises the structural elements, means known in the art for joining polymeric materials are suitable for connecting the structural elements, including solvent welding, adhesives, etc. In addition, conventional fasteners such as adhesives, brackets, nuts and bolts, screws, rivets, etc. may be employed to fasten the various structural elements to one another to provide an ensemble  69  according to the invention. In one preferred form of the invention, the linear frame members and hollow structural conduits are made from square metallic tubing having a cross section measurement, and the ends of the hollow structural conduits are fitted over holes in the side walls of the linear frame members in a sealing fashion, such as by a weld bead around the perimeter of the joint. The holes in the side walls of the linear frame members are of a lesser dimension than the cross section measurement of the square metallic tubing employed. In addition, although the hollow structural elements in FIG. 1 et al. all collectively define a square by virtue of each of the hollow structural elements comprising a portion that has an angle of about 90° along their length between their first end portion and their second end portion, the present invention contemplates other shapes for these hollow structural elements, including the case where the hollow structural elements are arcuate in shape and thus collectively define a circle when viewed as a whole. 
     The tabletop portion  10  preferably comprises a hollow box that in one preferred form of the invention is shaped substantially in the form of a rectangular solid as shown in the various figures. The purpose of the tabletop portion  10  is to provide buoyancy to the ensemble  69  of the invention as a whole. The tabletop portion  10  provides buoyancy by virtue of its being filled with air, which provides a buoyancy effect by displacing water with the air contained within the tabletop portion  10  when the ensemble  69  of the invention is placed into a body of water. By allowing water to be admitted into the structural elements of the ensemble  69  and by having the buoyancy provided by the centrally-located tabletop, an especially stable structure is provided upon which people may sit and enjoy a truly unique recreational experience of sitting at a table in the water. 
     Thus, the tabletop portion excludes water from its interior in order to provide a buoyancy to the ensemble  69  as a whole. In one preferred form, the tabletop is comprised of a floor portion, four wall portions, and a flat top portion. In one preferred form of the invention, the floor portion is provided with a square hole in its center. A section of square tubing functions as vertical support guide  31  and is placed through the hole and welded or attached using conventional means described elsewhere herein, either on the inside, outside, or both surfaces where the square tubing meets the floor portion. In such fashion, the tabletop may be lowered onto the second end portion of the vertical support  12 , for the case when the cross section of the vertical support  12  is square and of slightly smaller diameter than the vertical support guide  31 . Analogous arrangements are functionally-equivalent possibilities for cases when the tubing is circular in cross section, or has other cross-sectional geometries. In addition, the vertical support guide  31  may include a stop ( 50  in FIG. 8 a ) to limit the travel of the vertical support  12  in the bore defined by the vertical support guide  31 . According to one preferred form of the invention, the second end portion of the vertical support  12  is placed into the vertical support guide  31  and is welded in position. According to an alternate form of the invention, the second end portion of the vertical support  12  is placed into the vertical support guide  31  and is removably held in position by the use of conventional brackets and fasteners coupling the vertical support guide  31  to the vertical support  12 . One convenient means includes the use of a lynch pin disposed through a bore which is common to both the vertical support  12  and the vertical support guide  31  and which bore is disposed perpendicular to the length dimension of the vertical support  12 . By such provision, the tabletop portion is readily detachable from the remaining portions of the ensemble  69 . 
     The tabletop portion  10  may also, in an alternate form of the invention, be filled with a foamed material, such as expanded polystyrene. In any event, the tabletop portion is sufficiently buoyant to provide a degree of buoyancy to the ensemble  69  as a whole to float while said ensemble is disposed in a body of water and a total human mass in the range of 200 to 1000 lbs is disposed on the plurality of seating means present. According to a preferred form of the invention, the tabletop portion measures 3 feet wide by 3 feet long by 2 feet high for a total displacement of about 18 cubic feet which provides a maximum buoyancy of about 1100 pounds, which is more than adequate to support the device and four adult people. 
     The invention includes means for attaching weights to the framework, in order to adjust the degree of levelness of the tabletop for the various possible cases of persons having different weights seated on an ensemble according to the invention. Such means may be simple hooks where weights may be attached at various locations on the framework or other parts of the present invention, or may be a protruding flange such as at  66  in FIG. 2 where a weight may be placed. The present invention also contemplates the use of air entrained within a plastic or other membrane or enclosure, to be used to level the table top by affixing such contained air to any desired location of the framework or other elements of the invention. 
     Consideration must be given to the fact that although this invention has been described and disclosed in relation to certain preferred embodiments, obvious equivalent modifications and alterations thereof will become apparent to one of ordinary skill in this art upon reading and understanding this specification and the claims appended hereto. Accordingly, the presently disclosed invention is intended to cover all such modifications and alterations, and is limited only by the scope of the claims which follow.
