Filed Mar. 3, 1960, Ser. No. 12,525 12 Claims. (Cl. 311-89) The present invention relates broadly to a table, and in its specific phases to a novel table in which the top is formed of two halves hinged together for folding one onto the other, and in which the legs are uniquely mounted and also foldable, thereby providing for compact storage when not in use. The table is shown as octagonal and having peripheral pockets adapting it for playing poker or other card games, but no novelty is claimed for these characteristics by themselves alone.

Card tables have long been used and practically all of them have a non-foldable square or round top and have one-piece legs hinged on the under face of same. A few such tables have also been proposed with a folding top and equally spaced legs hinged on the underface of same. These latter constructions have substantially universally been rather complex in construction and not easily foldable without considerable practice. It was a recognition of this situation and the complete lack of a thoroughly satisfactory folding table with non-equally spaced legs foldably mounted on the under side of same which led to the conception and development of the present invention.

Accordingly among the objects of the present invention is the provision of a novel foldable table in which one half of the table top is foldable onto the other half before folding any of the legs, in which said other half is provided with a sufficient number of legs to stably support it both when in use and when said one half is folded onto it, and in which said one half is provided with a leg which stably supports it in position for use and may be easily folded after folding of said one half onto said other half while the latter is leg-supported, after which the table may be tilted on edge and the legs of said other half conveniently folded. Unusual compactness and convenience in folding is thus atttained, and the same is true of unfolding for use.

Another object is to provide a simple, novel and effec tive construction for pivotally connecting the legs with the table top and for rigidly bracing said legs when in operative position.

A further object is to provide a simple, novel and effective connecting means between upper and lower sections of some of the foldable legs.

Still further objects and advantages of the invention will appear as the description proceeds.

To the accomplishment of the foregoing and related ends, the invention, then, consists of the folding table means hereinafter fully described and particularly pointed out in the claims, the annexed drawings, and the following description setting forth in detail certain means for carrying out the invention, such disclosed means illustrating, however, but one of various ways in which the principle of the invention may be used.

In the annexed drawings:

While a preferred construction of my folding table is shown in the drawings, and will be rather specifically described, attention is invited to the possibilty of making further variations within the sprit and scope of the invention as herein shown and described.

One half 12a, FIGURE 1, of the table top is connected by conventional concealed hinges 13 to the other half 12. The half 12 is provided with two foldable, onepiece, and preferably tubular legs 14 near the ends of its hinged edge 15 and pivotally mounted on axes 16, FIGURE 1, transverse to said hinged edge, to fold i-nwardly into overlapping relation as shown in FIGURE 6,, in which they are parallel with said hinged edge 15. The half 12 also has a foldab'le, two piece, tubular leg 17 remote from the hinged edge 15 and centrally located with respect to the legs 14. The half 12a has a single tubular, two piece, leg 17a remote from its hinged edge 15a and located opposite the leg 17. The legs 17 and 17a, FIGURE 2, are each formed of two pivotally connected

sections

18 and 19 with the upper sections 18 pivoted on axes 20, FIGURE 1, which are parallel with the hinged edges 15 and 15a. The lower section 19 is foldable adjacent the side of upper sections 18, and the two

sections

18 and 19 are then jointly foldable inwardly as shown in FIGURE 6.

After use of the table, the half 12a is folded onto the half '12 before folding the leg 17a, as seen in dotted lines in FIGURE 5. This is done while the half 12 is stably supported by its three

legs

14 and 17. Then the leg 17a may be easily folded, after which the table may be turned on edge and the

legs

14 and 17 folded. The compact relation of elements shown in FIGURE 6 then exists for storage and may be maintained until further use of the table is required by a strap 21 and buckle 22 provided for the purpose. By reversing the folding steps, the table may be easily unfolded for use.

For mounting the two legs 14 and the two legs 17 and 17a, four brackets 23 are provided, said brackets being secured .to frames 24 and 24a embodied in the construction of the table top halves 12 and 126: respectively. All of the brackets 23 and elements associated therewith have certain structure in common, but each of the two brackets which mount the legs 17 and 17a has an additional bracket portion 23a, FIGURES 3 and 4. Rivets 25' are shown securing the various brackets to the

frames

24 and 24a. The construction of each bracket 23 and the association of elements therewith are shown best in FIGURES 3, 4, 5, 7, 8 and 9, and in the latter views the construction associated with one of the legs 14- i shown as typical.

The bracket 23 includes a vertically disposed, horizontally elongated plate 26, FIGURES 3 and 4, having an integral horizontally projecting arm 27 at one end. The other end 28 of the plate 26 is disposed at a widely obtuse angle to the major portion of said plate to conform to the

frame

24 or 24a and is provided with a lug 29 projecting in the same direction as the arm 27. The outer end portion of this arm 27 is outwardly offset away from the lug 29, as shown at 30.

The leg 14, FIGURES 7 and 8, is pivoted by means of a rivet 31 to the inner end portion of the arm 27, in the angle between this arm and the plate 26, FIGURES 3 and 4. An inclined brace 32, FIGURE 8, is secured at its lower end to the leg by means of a rivet 33; and the upper end of said brace is pivoted to the lug 29 by means of a rivet 34 which is alined with the leg-pivoting rivet 31. The leg and brace are thus swingable as a unit when folding the leg.

The rivet 31, FIGURE 8, may extend only through the wall of the leg. The rivet 33, however, extends diametrically through the leg and is specially shaped, at the end opposite the brace 32, to provide a projection 35 which extends radially from said leg. This projection, as shown in FIGURES 8 and 9, has a somewhat enlarged inner end portion 36 abutting the leg, a moderately tapered end portion 37 which is still larger than said portion 36, and which i largest at its outer end of this tapered portion 37 is preferably bevelled down to the portion 36, as shown at 39.

An inclined and pivoted brace link 40, FIGURES 3 and 7 is pivoted at its upper end to the free end of the bracket arm 27 by means of a rivet 41; and the lower end of this link 40 is connected with the leg through the instrumentality of the projection 35. The link 44) has a longitudinal slot 42 of a width to receive the portion 36 of the projection 35. The slot 42, however, has an enlarged lower end 43 in which the moderately tapered end portion 37 of the projection 35 is received and gripped, FIGURES 7 and 9, when the leg and link are in their extended operative positions. The link 40 thus P events folding of the leg until said link is so sprung from said moderately tapered portion 37 that the small-diameter portion 36 may enter the slot 42, at which time leg folding is permitted. The link 40 is tensioned laterally to snap outwardly and bind on the moderately tapered portion 37 when the leg is returned to operative extended position, thereby again wedgingly seating the portion 37 of the projection 35 in the enlarged slot end 43, which, preferably has a correspondingly taper to that of portion 27. During this snap movement of the link 49, the bevel 39 guides the moderately tapered portion 37 into the enlarged slot end 43 to firmly hold leg 14 in extended position.

The upper and

lower sections

18 and 19 of each of the legs 17 and 17a are preferably connected in a manner best seen in FIGURE 10. The

sections

18 and 19 abut on a line 44; and the upper section 13 has a knuckle 45 spaced above said line 44 and welded to said upper section. The lower section 19 has a welded-on arm 46 which freely projects above the line 44 and is provided with portions which straddle the knuckle 45 and abut the ends of the latter. On of these portions is shown at 460. The two portions 46a are pivotally connected to the knuckle by a rivet 47 extending therethrough.

At the side of the upper leg section 18, opposite to that carrying the knuckle 45, said leg section has a longitudinal slot 48. At the same side of the leg section 18, a vertically movable and slotted slide 49 is mounted by a sholdered rivet 50 to slide on said leg section 18. A central lower end portion of the slide 49 is inwardly stamped to provide a projection 51 extending freely through the slot 48, in leg section 18 and a tongue 52 extending downwardly from said projection. When the two

leg sections

18 and 19 are alined, and the slide 49 occupies a lowered position, as shown in FIGURE 1O, the tongue 52 abuts the inner side of the lower leg section 19 and prevents this leg section 19 from swinging about hinge rivet 47 with respect to the upper section 18. When the slide 49 is moved upward to released position, however, the section 19 may be folded onto the section 18 about hinge rivet 47 and the two sections then unitarily dfolded into compact relation with the table top as shown in FIGURE 6.

From the foregoing, it will be seen that novel and advantageous construction has been disclosed for attaining the desired ends. However, attention is again invited to the possibility of making variations within the obvious spirit and scope of the invention as shown and described herein. For ease of describing the invention when the table is in upright position as shown in FIGURES 2 and 5, directional terms such as upper, lower, inward, outward, downwardly, upward, et cetera have been used, but such are not to be considered as limiting the invention since the relationship of the parts to one another is the same regardless of the position taken by the table.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the table and combinations herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.
