SHEET 20? 2 FOLDING TABLE BACKGROUND OF THE INVENTION 1. Field of the Invention.
Folding tables of the type generally used as cocktail tables, serving tables and the like. The invention is also applicable to other kinds of folding tables, regardless of the nature and purpose of their use.
2. Description of the Prior Art.
The closest prior-art known to applicant consists of conventional folding tables wherein the legs or leg assemblies are held in their respective operative positions by means of latching or locking means. It is necessary, in moving the legs of folding tables from operative to inoperative position, to disengage a latch or unlock a locking mechanism. Illustrative of such prior art is Ritter U.S. Pat. No. 1,944,757, issued on Jan. 23, 1934. Another pertinent prior art patent is Benedict U.S. Pat. No. 310,245, which issued on Jan. 6, 1885. In this patent the folding legs are held in operative position by means of a locking detent, and a spring is employed to maintain the legs in locked position with respect to the detent. Still another pertinent prior art patent known to applicant is Wigell U.S. Pat. No. 2,684,883, issued July 27, 1954.
None of the prior art folding tables known to applicant is provided with folding legs which are biased in operative or inoperative position, as the case may be, by the use of spring toggle means.
SUMMARY OF THE INVENTION.
The present invention comprises a folding table consisting of a table top and a plurality of pivotally mounted leg assemblies and spring toggle means for biasing and holding the leg assemblies in either generally vertical operative position or generally horizontal inoperative position. In the preferred form of this invention, each folding table is provided with a pair of oppositely disposed leg assemblies, each leg assembly consisting of a pair of legs supported in fixed positions relative to each other by means of cross-bracing. In such case, only a single spring toggle means is needed for each leg assembly, that is, only two spring toggle means for four legs. The invention is equally applicable to folding tables with four separately operable legs, each of which is pivotally secured to the table top and each of which is provided with its own individual spring toggle means. In such case the table would, of course, have four separate spring toggle means for its four separate legs.
The basic advantage in the present invention over conventional and prior foldingtables resides in the fact that there is no need for latching or locking means in a folding table made in accordance with the present invention and, consequently, there is no need to unlatch or unlock the legs or leg assemblies when swinging them from operative to inoperative position, or vice versa. Combined with this feature is the speed and ease with which the legs can be swung from operative to inlegs are projected in operative position or retracted in inoperative position. Stated differently, this arrangement makes it possible to swing the legs into either position while holding the table top between ones hands. It is not necessary to support the table by other means while latching or.locking means are actuated. Thus it is entirely feasible to carry and use the table, with its legs retracted, as a serving tray or the like, and, when desired, it is equally feasible to lower the legs into supportive positions in order to convert the tray into a cocktail table or the like. This would be done by holding the ends of the table top between the palms of the hands while using the fingers to engage crossbars on the leg assemblies and to cause said leg assemblies to swing into operative or inoperative position, as the case may be, against the spring toggle action.
BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a perspective view of a folding table made in accordance with the present invention, said table being shown in folded condition.
FIG. 2 is abottom view of said folded table.
F IG, 3 is an end view thereof, when extended to operative position.
FIG. 4 is a side view of said table when extended in operative position.
FIG. 5 is an enlarged longitudinal section on the-line 55 of FIG. 2, showing the leg assemblies of the'folding table in retracted position.
FIG. 6 isa fragmentary sectional view of the lefthand end of the folding table, as viewed in FIG. 5, but showing the leg assembly of that end extended to operative position. 3
FIG. 7 is an enlarged transverse section on the line 77 of FIG. 1.

DESCRIPTION OF PREFERRED EMBODIMENT OF THE INVENTION The invention is illustrated in the accompanying drawing, wherein folding table .10 made in accordance with the principles. of this invention comprises atable top12, a pair of leg assemblies 14 and 15, respectively, and a pair of spring toggle means 18 and 20, respectively. It will be-observed that the table top comprises a horizontal board 22 or the like, a pair of end members 220 and 22b, respectively, and a pair of side rails 22 and 22d, respectively. The precise configuration of these end members and side rails is not significant in relation to the present invention, and what is shown in the drawing should be understood as being merely illustrative.
Each leg is pivotally fastened by means of a pivot pin 30 to one of the side rails 22c, 22d of the table top. Pins 30 of each pair of legs constituting a single assembly are, of course, axially aligned, so that each said leg assembly pivots about a common axis. It will also be noted that spring 18 is secured by means of fastening element 180 to end member 220, and the opposite end of the spring is secured by means of fastening element 18b to one of the legs 14a, 14b. The precise locations of fastening elements 18a and 18b on end member 22a and leg 14a or 14b are determined-by the necessities of a toggle action. That is, when the leg assembly 14 is in its generally vertical operative position, spring 18 is disposed on one side of adjacent pivot pin 30. When the leg assembly is swung upwardly to generally horizontal position, substantially parallel to the table top, spring 18 is moved to the opposite side of said pivot pin. Stated differently, spring 18 moves across the pivotal axis of the leg assembly when said leg assembly is swung from projected to retracted position or vice versa. In either position of the leg assembly, pivot pin 30 and the two points ( fastening elements 18a and 18b) at which 'the spring is secured to the table top (end member 22a) and the leg assembly (leg'l4a or 14b) define the three points of a generally isosceles triangle,
' the pivot pin 30 constituting its apical angle and the two fastening points of the spring constitute the base angles.
It will, of course, be understood that a truly geometrical isosceles triangle is not required in this invention. it may be that a stronger tension force would be desired for holding the leg assemblies in projected operative positions than in holding them in retracted inoperative positions. it may also be found desirable to lessen the effect needed to swing the leg assemblies from their retracted to their projected positions. These and other requirements may necessitate a different placement of the ends of the spring from the base angles of an isosceles triangle. Where the spring forces are balanced equally, as between the projected and retracted positions of the leg assemblies, the spring will move equal distances on opposite sides of the pivot pin. What has specifically been said regarding spring 18 and leg assembly 14 also applies to spring 20 and leg assembly 16.
it will be noted that the legs are tapered on one side along their respective lengths, such that when the leg assemblies are folded over into retracted positions one upon the other, the tapered sides of the legs will juxtapose. The non-tapered sides of the legs will thereby as sume generally parallel positions. This tapered configuration of the legs makes for'a more compact arrangement when the legs are folded over into their respective retracted positions.
The foregoing is illustrative of a preferred form of this invention, and it will be understood that variations thereof are fully contemplated within the, broad scope of the appended claims.
