FOLDABLE TABLE AND BENCH ASSEMBLY BACKGROUND OF THE INVENTION Many attempts have been made to produce a foldable table which when in extended condition serves as a flat surface upon which meals may be served or upon which other types of work may be accomplished. Many such tables have successfully been produced and function quite well. However, so far as is known, all such conventional tables require auxiliary seating means apart from the table construction, thus, to the extent that tables are foldable, defeating the purpose of the foldable table, namely, its compactness for storage purposes. In foldable table structures that require such auxiliary seating, the seats or chairs must be stored apart from the table construction and are of course susceptible to loss. Accordingly, it is one of the important objects of the present invention to provide a foldable table construction incorporating means for accomplishing the seating function.

In the production of a foldable table construction, it is important that the structure not only be sturdy when used in extended condition, but that it be compact and easily carried when in folded condition. Accordingly, it is another object of the invention to provide a foldable table including means for accomplishing the seating function, which fulfills these advantages.

So far as is known, foldable tables do not exist which incorporate seating means, and which accommodate such seating means at all four sides of the table. Accordingly, it is another important object of the invention to provide a foldable table incorporating seating means on all four sides of the table.

Portable tables capable of being folded into a compact carrying case are frequently used out of doors on terrain that is relatively uneven. Conventional fourlegged tables do not provide for uneveness of terrain and therefore remain somewhat unstable when set up on such terrain. Accordingly, another object of the present invention is the provision of a foldable table of the picnic type capable of being folded into a compact case, yet when extended on uneven terrain may be adjusted to stabilize the structure.

Not only do conventional foldable tables not incorporate means for seating occupants at the table, but in most such conventional tables, whatever stabilizing means are used frequently interfere with the comfort of the occupant seated at the table, in that such stabilizing means frequently take the form of angularly disposed braces extending between legs and table top, thus occupying space that might ordinarily be used by a person to place his legs or knees. Accordingly, another object of the present invention is to provide a foldable table incorporating means for seating occupants at the table, said means also functioning to stabilize the table when in extended condition.

BRIEF SUMMARY OF THE INVENTION In terms of broad inclusion, the foldable table incorporating seating means comprises a pair of flat elongated panels, preferably fabricated from metal, each panel being provided with a peripheral flange. Placement of the panels edge to edge creates a wide flat surface, and hinge means disposed between the two panels permits the two panels to be folded together to form an enclosed compartment in which the legs may be stored. Leg structures are pivoted to opposite corners of the associated panels, means being provided on each leg structure to lock the leg structure in extended position. Means are also provided on each leg structure adapted to detachably support a bench thereon and which, in addition to functioning as a seat for occupants at the table, cooperates with the leg structure to stabilize the table. Means are provided on the peripheral flanges for locking the two panels into compartment forming position when folded together. In like manner, handle means are provided on the peripheral flange for lifting the folded table.

DESCRIPTION OF THE PREFERRED EMBODIMENT In terms of 'greater detail, and referring to the embodiment illustrated in FIGS. 1 through 5, when folded the foldable table appears as an elongated, compact suitcase-like structure designated generally by the numeral 2. The foldable table is retained in folded condition by appropriate latches 3, and may be lifted for carrying purposes by appropriate handles 4. Thus, the folded table may be easily stored in a closet, or in a garage, and for purposes of carrying, may be placed in the baggage compartment of an automobile, or on a baggage rack carried on the roof of an automobile. When folded, it is attractive in appearance,and gives no indication of its functional characteristics.

When unfolded, the structure comprises a pair of substantially identical flat panels 6 and 7, preferably fabricated from heavy gauge aluminum which embodies both the quality of lightness and strength, the table top panels each being provided with peripheral end skirts 8 and 9 at opposite ends thereof, and peripheral side skirts 12 and 13 on opposite sides thereof. As used herein, the phrase table top is intended to include the panels 6 and 7 and the peripheral end and side skirts. As illustrated in FIGS. 3, 4 and 13, the associated side skirts 13 of the table top panels 6 and 7 are disposed in side-by-side relationship and are joined in a pivotal connection by an appropriate hinge structure 14. As shown, the hinge structure is permanently attached through appropriate rivets to the inside surface of the associated end flanges 8 and 9 at each end of the table top. It will thus be seen that the table panels 6 and 7 with their peripheral skirts, by virtue of the interposition of the pivotal hinge structure 14, may be pivoted together into the relationship illustrated in FIG. 1, wherein the edges of the peripheral side and end skirts on associated tabel panels 6 and 7 abut edgewise so as to form a hollow interior within which the leg and bench structures may be stored as will hereinafter be explained in greater detail.

Referring to FIGS. 2 and 3, the table top is provided with four separate leg assemblies or structures designated generally by numerals 16, 17, 18 and 19. In the interest of brevity, only one such leg assembly will be described, it being understood that each is identical with the others. Accordingly, each leg assembly comprises an elongated tubular leg member 21, preferably fabricated from tubular aluminum and provided at its lower end with a resilient cap 22 and its opposite end bored to provide transverse openings 23 (FIG. 9) through which a pivot pin 24 may extend to pivotally mount the elongated tubular leg member 21 to an appropriate bracket 26 suitably secured to the table top by appropriate means such as by spot welding.

Each leg assembly is provided with a pair of auxiliary leg structures which function also as bench support means, and are designated generally by the numerals 27 and 28. Each bench support 27 includes a horizontal section 29 merging smooth through an appropriate radius 31 with a vertically disposed leg section 32. T attach the bench support 27 to the vertically disposed tubular leg 21, the horizontal section 29 is provided at one end with a sleeve 33 appropriately welded to the end of the horizontal section 29 and having an inner diameter such that the sleeve 33 forms a snug rotatable fit on the exterior periphery of the tubular leg 21.

In like manner, the bench support 28 includes a horizontal section 34 merging smoothly through radius 36 with a downwardly depending leg section 37. The inner end of the horizontal section 34 is in like manner provided with a sleeve 38, the diameter of which is such as to closely surround the outer periphery of the tubular leg 21 so as to permit rotatable adjustment of the bench support structure 28 about the vertical leg. The bench support structures 27 and 28 are both retained in position in the tubular leg 21 by pop rivets 39 and 41 positioned above and below the assembly, as shown so as to permit rototable adjustment of the bench support structures and preclude axial displacement thereof in relation to the longitudinal axis of the tubular leg 21. This construction of the auxiliary legs or bench support structure 27 and 28 is clearly illustrated in FIGS.

and 11.

Each of the leg assemblies including the auxiliary leg or bench support structure is pivotally mounted in a corner of the table top panels 6 and 7 by the bracket structure 26 illustrated in FIGS. 8 and 9 Referring to FIG. 8, it will there be seen that the bracket includes a base portion 42 appropriately spot welded or riveted to the associated skirt 8 of the table top, and is also provided with a projecting flange 43 apertured as shown in FIG. 9 to permit the passage of pivot pin 24 tov secure the upper end of leg 21 to the bracket. Extending substantially parallel to flange 43 and forming an integral part of the bracket, is an elongated angular member 44 having a job 46 therein, and having its remote end 47 appropriately anchored to the side skirt 12 as shown. The bracket 26 is preferably fabricated from an appropriate metal so as to have the requisite strength, steel being preferred for this purpose.

To maintain each of the leg assemblies in an upright position in extended form, each leg 21 is provided with a pivotally mounted two-link brace designated generally by the numeral 48, one link being pivoted at 49 to the remote end 47 of the bracket 26 in the associated skirt of the table top, while the other end of the two part link is appropriately pivoted as at 51 to the leg 21. The locking link is proportioned so that when the legs are in extended condition as illustrated in FIG. 2, the link extends diagonally across the corner of the table between each leg and the associated peripheral flange or skirt of the table top.

Referring to FIG. 3, it will be seen that the bracket 26 is appropriate for pivotally mounting and anchoring the leg assemblies 16 and 18, but that for the purpose of pivotally mounting the leg assemblies 17 and 19, the bracket here designated as 26, is modified somewhat in that the job 46' is accentuated to permit the bracket 26' to be mounted at a point spaced from the associated side skirts 12 as shown. In the embodiment illustrated in FIG. 3, such additional spacing is required to accommodate the legs in their folded condition as shown wherein the leg assemblies 18 and 19 lie in planar alignment nestled together within the one-half of the table top formed by table panel 7-9, whereas the other pair of leg assemblies 16 and 17 lie nestled together in planar alignment within the one-half of the table top formed by table panel 6-9.

In order to stabilize the table thus formed as illustrated in FIG. 2, and to provide for seating occupants at all four sides of the table, bench support structures 28 are rotated out into the position illustrated in FIG. 2, in which the horizontal section 34 extends generally longitudinally of the table, while leg support structures 27 are pivoted outwardly so that horizontal section 29 extends generally transverse of the longitudinal dimension of the table. Each of the horizontal sections 29 and 34 of the leg structures 27 and 28 is provided on its top surface with a plurality of apertures 52 (FIG. 11), each of the apertures being adapted to receive a projecting lug 53 formed as an extension on the end of a channel brace member 54 (FIG. 12) adapted to straddle the underlying tubular horizontal section 29 or 34.

One such channel brace 54 is appropriately welded across each end of a bench structure designated generally by the numeral 56 and including a top panel 57 having a peripheral flange 58 thereabout to lend rigidity to the bench structure, which is preferably fabricated from an appropriate sheet metal, the bench structure being further strengthened by a hat-section insert of sheet metal designated by the numeral 59. The hatsection strengthening rib is conveniently spot welded within the confines of the peripheral flange 58 so that to a large extent the underside of the bench structure also provides a relatively smooth surface.

As illustrated in FIG. 12, each of the channel braces 54 extends transversely across the end of the bench structure so that when the bench structure 56 is mounted across the associated pairs of leg assemblies I as illustrated in FIG. 2, engagement of the lugs 53 in the appropriate apertures 52 locks the bench structure to the associated bench support structures in a manner to prevent inadvertant release thereof, and in a manner to solidly retain the associated bench support or auxiliary leg structure against pivotal movement about the supporting tubular leg 21. It will thus be seen that because of the multiplicity of apertures 52 formed in the horizontal sections of the bench support structure 27 and 28, the benches may be adjusted to provide the appropriate spacing in respect to the associated edge of the table, thus more comfortably accommodating both adults and children.

Referring to FIGS. 3, 4 and 5, it will there be seen that when the table is folded into the condition illustrated in FIG. 1, the bench structures 56 and 56', the latter reference number referring to the relatively shorter benches associated with the ends of the table illustrated in FIG. 2, are superimposed over the underlying leg structures and sit neatly within the confines of the peripheral flanges 8, 9 and 12 so that when the table is folded along the hinge line 14, the leg assemblies and bench structures are retained compactly within the case formed by the table top in closed condition.

The embodiment of the invention illustrated in FIG. 6 is substantially similar to the embodiment of the invention illustrated in FIGS. 2 and 3, with the exception that in FIG. 6, the table in extended condition is substantially square as opposed to being substantially elongated in a rectangular fashion. Thus, in FIG. 6, the widths of the table top panels 7 and 6' have been increased in width so as to accommodate the leg assemblies 16-19 in a manner to permit the bench structures 56 being superimposed one above the other in pairs as illustrated in FIG. 7, and nestled in the space between the peripheral flanges 13 and the associated leg assemblies as shown. In other respects, the structures are identical. To accommodate the leg assemblies in the manner illustrated in FIGS. 6 and 7, the anchor brackets 26 are all uniform in their construction and correspond to the structure illustrated in FIG. 8. In mounting the anchor brackets to the associated table, because of the superposition of one pair of leg assemblies over an underlying pair thereof, the anchor brackets of the superposed pair is off-set somewhat so as to permit such superposition without effecting a strain on the peripheral flange of the table top. In this embodiment of the invention it will be noted that the benches 56 are of equal length, inasmuch as the table of this embodiment is substantially square.

During storage, the table top is folded as illustrated in FIG. 1. For use, the table is unfolded and assembled as illustrated in FIG. 2. To effect such unfolding, the case as illustrated in FIG. 1 is placed on the floor or ground in the attitude illustrated in FIG. 1, and the latches 3 are unlatched and the table top unfolded into the position illustrated in FIG. 3. From this position,

each of the leg assemblies16-19 is individually pivoted until the tubular leg 21 of each assembly stands perpendicular to the table top and the cross brace 48 is in locked condition. In this position of the leg assemblies, the bench support structures 27 and 28 remain in their relative positions with respect to the tubular leg members 21, thus permitting the table top to be inverted into right-sideup position (FIG. 2) without regard to the auxiliary leg or bench support structures 27 and 28. The table top will be appropriately supported by the now downwardly depending tubular legs 21 regardless of the pivotal position of the auxiliary leg or bench support members 27 and 28.

When the table top has been inverted into its rightside-up position, the bench supports 27 and 28 may be pivoted from the position illustrated in FIG. 10, for instance, into the positions illustrated in FIG. 2, wherein the benches may be applied to the bench support structures so as to stabilize the entire table structure. It will of course be obvious that from the position of the parts illustrated in FIG. 3, before the leg assemblies are pivoted into an upright position, the bench structures 56 are removed and set aside until the table has been inverted into its right-side-up position.

In the event it is not desirable to utilize all four benches, the bench structures 56' extending across the ends of the table in FIG. 2 may be removed, and the associated bench support structures 28 pivoted inboard of the table so as to be out of the way, thus leaving an elongated table having bench structures on opposite long sides thereof. On the other hand, if desired, the long benches 56 may be removed while the short benches 56' may be retained, the bench support structures 27 being folded inwardly so as to be out of the way, thus forming an elongated table having benches only at opposite short ends of the table. Because of the versatility of the leg assemblies of the foldable table forming the subject matter of this invention, it is particularly adapted to be set up in a corner. For instance, one long bench structure and one short bench structure may be removed from the table assembly, and the associated bench support structures may be folded inwardly under the table so as to be out of the way. In such condition, the table may easily be pushed into a corner so that benches or seating accommodations are provided on two adjacent sides of the table but not on the two sides that are contiguous to the walls forming the corner. On the other hand, where seating accommodations are not necessary, the bench structures may all be removed, and the bench support structures 27 and 28 swiveled inwardly under the table where they are either out of the way or provide an auxiliary support and stability to the table for use for whatever purpose desired.
