In the region of the forward end of the table manner, to the le 8 d t0 the rear leg b s is mounted a U-shaped member H, the legs l5 Ill and I2. The upper ends of the leg Spreaders and I6 of which have outwardly turned ends 11 are pivoted to the legs at points and 35, which adapted for reception in spaced brackets l8 which points may be at below the Pivotal mountings are screwed or otherwise fixedly secured to the 1. Each leg spreader member has the lower end 45 under face of the table. The brackets lflprovide formed in accordance with the disclosure of Fig. pivotal mountings whereby the U-shaped member 3. The lower end of each leg sp a P may be moved, by means of a handle IS, in a lonably is turned rearwardlyf'as at 36, at substangitudinal plane which is perpendicular to the tially right angles to the plane thereof, and in plane of the table. At the locations 20 and 2|, the region of the turn or bend each has formed 50 the intermediate portion 22 of the U-shaped therein an elongated slot 31 which is included member is mounted pivotally upon the rear leg in the vbend. Each of the slots is adapted for braces I 0 and i2, respectively, near the forward reception of a stabilizing rod, the heads 30 of ends thereof. Thus, it will be observed that which are adapted to abut the concave areas when the handle 19 is grasped for moving the 38 of the ends 3|.

A perforated lug :0, extends from each leg spreader member in substantial perpendicularity thereto, and provides a means whereby the leg spreaders may be pivotally mounted upon the inner facu of the rear leg braces, as indicated at 4| and 4|. It will be' observed that the pivot 40 is spacedfrom. the adjacent pivot 9; Said pivot 4| may be referred to as a shiftable pivotal mounting for the lower end of the leg spreader, because the eifect of moving the brace I! upwardly about its pivot I, is to move upwardly also the pivotal mounting N, to a position closer to the pivot and likewise, the shiftable pivot ll is moved upwardly closer to the pivot 34 when the brace I0 is moved upwardly about its pivot 0. Since the pivots II and I! are fixed relative to the legs of the device, the spreader members therefore are subjected to a longitudinal compressive strain; and inasmuch as the spreader members are still enough to resist bending, the legs I must move outwardly due to the compressive strain imposed upon the spreader members by the upward movement of the shiftable pivots and Ii.

From the foregoing, it should readily be understood that by grasping the handle it (Fig. l) and moving it forwardly through an arc toward the table end It, the shiftable pivotal connections II and 4| will move in a direction away from the pivots I4 and 3!, whereby topull the legs I toward one another, until finally they assume thesubstantially parallel relationship indicated in Fig. 2; and conversely, when the handle member I! is moved from the position of Fig. 2 rearwardly through an are determined by the length of the arms II and II, the distance decreases between the uppermost leg spreader pivots and the shiftable pivots ll and II, thereby setting up in-the leg spreaders the longitudinally compressive force which is translated into outward movement of the legs as explained above.

The length of the stabilizingrods II and 24 is such thatthe knobs ll thereof, upon rearward projection of the legs 8 by the action of handle is, will contact the abutments fl shortly before the members II and I4 attain a dead-center alignment, so that the handle I! assumes its final position, (as shown in Fig. l), with a snap action. Thus the various parts of the structure are maintain under a limited strain when the device is in use, so as to insure a degree of rigidity precluding wobbling of the structure.

when the device is collapsed, all parts of the supporting structure are disposed within the limits of the side edges of the table, thereby facilitating storage and carrying of the device from place to place. The various parts lie so fiat upon the table, when the device is collapsed, that it can be stored in acontainer approximately three inches in depth, and this advantage is one of I considerable merit. 4
