v- M ATTORNEYS United States Patent 3,108,556 FQLDING TABLE Frederick D. Knohloclr, Bloomfield Hills, Mich. Auto Glass Mfg. Co., 8761 Grinneli, Detroit 13, Mich.)

Filed Nov. 7, 196%, Ser. No. 67,542 14 Qiaims. (Cl. 1tl3l24) This invention relates to folding tables and particularly to folding tables of the type readily folded into flat compact form for storage and which can be unfolded and erected without the use of tools.

In the patent to Frederick D. Knoblock and Albert C. Koett, 2,902,325, titled Folding Support Base for Table Top, issued September 1, 1959, there is disclosed a foldable base on which a tray is adapted to rest which comprises side members each made of a single length of elongated tubing and having a U-shape. Each side mem her is positioned so that the lower arm is adapted to rest upon the floor and the upper arm is adapted to support the table. The members are spaced apart with their bight portions extending upwardly. A main frame member comprising a single length of elongated tubing of inverted U-shape is provided with the legs thereof parallel to the bight portions of the side members. The bight portions of the side members are hinged to the legs of the main frame member and the side members are adapted to be folded into compact relationship adjacent the main frame member.

It is an object of this invention to provide an improved folding table of such a construction which is more compact.

lt is a further object of the invention to provide such a table which includes novel hinge means.

It is a further object of the invention to provide such a table which includes novel means for mounting a tray or table top thereon, which top is adapted to remain as a part of the table both the folded and unfolded conditions.

It is a further object of the invention to provide such a table which can be manufactured at relatively low cost.

FIG. 9 is a fragmentary sectional view taken along the line 99 in FIG. 6.

FIG. 10 is a fragmentary plan view of a modified form of table.

Referring to FlG. 1, the folding table comprises four elements, namely, a main frame member 20, side frame 3-,l8,55 Fatented Oct. 29, 1963 members 21a, 21b, and a tray 22. Main frame member 2% is made of a single length of tubing and has an inverted U-shape comprising generally vertical legs 23a, 2312 connected by a horizontal cross or bight portion 24. Each side member 21a, 21b is also made of a single length of tubing and comprises horizontal legs 25a, 25b, 26a,-26b connected by a vertical cross or bight portion 27a, 27b. Longitudinally spaced hinges 23 pivot each side member 210, Mb to the vertical legs 23a, 23b of the main frame member 20 for swinging movement about the axis of vertical bight portions 27a, 27b. As shown, for example, in FIG. 7, each hinge 28 comprises a block 29, preferably of plastic material, which is fixed to a vertical leg 23a by a pair of bolts 3% extending through spaced openings 31 in the leg 23:: and having acorn nuts 32 threaded on the ends thereof. Each block 29 comprises a pair of spaced flexible fingers 33 that are snapped over the bight portion 27:: of the adjacent side member 21a so that the side member 21:: is hinged to the block 2? and, in turn, the main frame member 20. The use of the plastic 29 not only permits the hinge to be disconnected but, in addition, provides for a freely pivoted hinge. By this arrangement, each side member 21a, 21b is adapted to swing about an axis parallel to the axis of the legs 23a, 23b of the mainframe 26.

As shown in FIG. 2, the bight portion 24 of the main frame member 20 is bent intermediate its end nearer one leg 23b than the other leg 23a. The extent of the bent portion 24a is such that the one leg 23b lies in a plane with the leg 27a of the side member Zia when the table is in folded condition. As shown, when the side member 21a is brought into position with its plane generally parallel to the plane of the main frame member, the other side member 21b can then be pivoted to bring its plane into parallelism with the main frame member 20 and the first side member 21a.

Tray 22 is adapted to be mounted on the bight portion 24 of main frame 20 for swinging movement about two axes, one is the axis of the bight portion 24 and the other is an axis at a right angle to the axis of the bight portion 24- and at a right angle to the plane of the tray;

-so that the tray can be brought into position, as shown in FIG. 1, wherein it is supported by the upper legs 25a, 25b and bight portion 24 or so that it can be pivoted into a folded'position with its side members Zla, 21b, as shown in FIGS. 2 and 3, parallel to the plane of the main frame member 20'.

The hinge joint 35 by which this arrangement is achieved is shown in FIGS. 4 and 5 and comprises a right angle bracket 36 to which tray 22 is pivoted by a rivet 37 for swinging movement about an axis at right angles to the plane of the tray. As shown in FIG. 4, a shim 38 is provided between one leg of the bracket 36 and the tray to facilitate the pivoting action. A block 39, preferably of plastic material, is fastened to the other leg of the bracket 36 by nivets. Block 39 includes a pair of spaced flexible fingers 40 that are adapted to snap over the bight portion 24 of main frame member 20 to pivot the block 39 and, in turn, the bracket 36 and tray 22 to hhe bight portion 24. In this fashion, the tray 22 can be pivoted or swung up or down with respect to the bight portion 24 and can also be rotated about an axis at right angles to the axis of the bight portion 24-.

When the tray 22 is brought into position on the unfolded legs 25a, 25b of side members 21a, 21b, the tray 22 is removably fastened thereto by blocks 41, preferably of plastic, fixed on the underside of the tray by rivets 42 and having spaced flexible fingers 43 that snap over the upper legs 25a, 25b of side members 21a, 21b. As shown in FIGS. 6 and 8, the blocks 41 are so positioned that they engage to the free ends of the legs 25a, 25b of side members 21.

In order to provide even greater rigidity, rubber bumpers 45 are fastened to the tops of legs 25a, 25b intermediate their ends and at the top of member 24 to engage the underside of the tray 22 (FIG. 9).

As shown in FIGS. 1 and 6, in the unfolded condition, the planes of the side members 21a, 21b are at right angles to the plane of the main frame member 20 with the lower legs 26a, 26b of side members 21a, 21b engaging the floor. The lower ends 23c, 23d of the legs 23a, 23b of main frame member 20 extend forwardly and engage the floor. The bight portion 24 of the main frame member 20 and the upper legs 25a, 25b of the side frame members 21a, 21b in substantially the same plane when the blocks 41 on the underside of the tray 22 are engaging the upper legs 25a, 25b adjacent their free ends.

In order to collapse or fold the table, the tray 22 is lifted upwardly disengaging the fingers 43 on the blocks 41 from the legs 25a, 25b. The tray 22 is then swung about the axis of the rivet 37 180 degrees (FIG. 4) and then permitted to swing downwardly about the axis of the bight portion 24, swinging the block 39 and assuming the position shown in FIG. 3. The one side member 2111 may be then folded into position as shown in FIG. 2 followed by the other side member 21b.

As shown in FIGS. 4, and 6, screws 47 locate the position where block 39 on tray 22 engages bight portion 24. Longitudinally spaced screws 48 on legs 27a and 27b determine the relative longitudinal positions of the main frame member 20 and side members 21a, 21b (FIGS. 1 and 3).

In the form of the invention shown in FIG. 10, the hinge assemblies 28 are reversed in their arrangement, the hinge assemblies being fixed to the vertical legs of members 21a, 21b and hinged about the vertical legs of side members 20 and adapted to removably or detachably engage the vertical legs of the main frame member 20. This form of the invention folds in substantially the same manner as the other form of the invention and involves a reversal of the leg on which the hinge means are mounted. This form increases the distance between the side members 21a, 21b when the table is unfolded.

Instead of providing the hinge 35 on the tray 22 in such a manner that it engages the bight portion 24, the hinge 35 can be positioned on the tray 22 so that it engages the upper horizontal leg 251] of side frame member 21b. In such a case, the block 41 on the tray 22 which normally engages the upper horizontal leg 25b is repositioned so that it engages the bight portion 24 of the main frame member 20.

It can thus be seen that there has been provided an improved folding table construction which is more compact; which involves novel hinge means; and wherein the tray remains as a part of the folded or unfolded construction. Because of the use of preformed blocks of plastic or the like, rivets and bolts, the overall cost of manufacture of the folding table is kept at a minimum. In each form of the invention, the side frame members are hinged for swinging movement about the vertical legs of either the main frame member or the side frame members. Since the hinges are disconnectable, the side and frame members may be readily interchanged thereby facilitating the handling of the parts during shipment and storage by the seller. The folding table can be readily disassembled without marring the finish of any of the parts.
