12 Claims. (Cl. 311-88) This invention relates to folding tables of the Fig. 4 is a section on the line 44 of Fig. 2 but type in which either the tops of thelegs or the showing the leg partly extended; upper ends of the leg bracing links are slidably ,Figs. 5 and 6 are broken side views showin connected to the table top to permit the legs the relationship between the pivot pin and its 5 to be extended or retracted.

The angle bars iii are spaced the crossing of the cross braces between the table apart sufficiently to leave room between the bars legs and the plate by whlch they are bound and the legs when in closed position for the 50 ge t I links 2|, and spacing washers 26 are provided Fig. 2 is a o tom plan vlew of the same Wlth on the rod 20 between the ends of the legs and the le s folded; the angle bars.
Fig. 3 is an end elevation of the same with the As shown, the legs are braced by means of legs folded;
The rod 2|) most desirably and as shown is a round bar of steel or other suitable elastic material, and the ends of the bar beyond the ends of the legs are flattened, as by being cut away on one side, as most clearly shown in Figs. 5 and 6, so that the thickness of the ends in one direction is less than the diameter or thickness of the bar; and the slots H are narrower than the diameter of the bar and most desirably of a widthv just sufficient to take the ends of the bar with an easy sliding fit when the bar is turned so that the flat sides of the ends are parallel with the edge of the slot, as shown in Figs. 1 and 5, except that at its inner end each of the slots has an enlargement which is of circular form and of a size to receive the ends of the rod when turned to any angular position, or to receive the unreduced cylindrical rod. Whenthe legs are in folded position and during the opening and closing movements of the legs with the ends of the rod travelling in the slots, the fiat sides of the rod ends are parallel to the edge of the slot. When the legs are in their fully extended position, the ends of the rod are in the enlarged end portions of the slots, and may then be turned to an angular position such as shown in Fig. 6, and when so turned the legs are thereby securely locked in extended position, since when the rod ends are so turned it is impossible for them to re-enter the narrower portion of the slots.
In order to prevent endwise movement of the rod after assembly when its ends are in the enlarged end portions of the slots, the holes in the spacing washers 26 are of the segmental form of the ends of the rod 2|] and thus serve as retaining means, holding the rod against such movement.
In the table shown in Figs. 1 to 7, the turning of the rod 26 to lock the legs when they have been swung out to their extended position is effected automatically. For this purpose, the rod 20 is provided with a bent plate 27 welded or otherwise attached thereto at the middle thereof, and one end of this plate 2'! extends in position to engage an edge of the angle bar i9 so that as the legs are swung outward away from the table and their upper ends moved inward from the end of the table, the angle bar, as the legs pivot on the rod 29, forces the engaged end of plate 27 upward; and since the ends of the rod cannot turn in the slots until they reach the enlarged inner end of the slots, the middle portion of the rod is turned slightly and forced upward as shown in Fig. 4 and by dotted lines in Fig. 5, thus putting the ends of the rod under torsional strain so that when the rod ends are moved into the enlarged end portions of the slots the ends turn to the angular position shown in Fig. 6. With the rod ends in this angular position they cannot re-enter the slots, and the legs are thus securely locked in their extended position.
When the rod 20 is in looking position, the inwardly extending end of the plate 21 is turned down away from the table top, as shown in Fig. 6, and this end of the plate serves as means whereby, by pressing it upward toward the table top, the rod. may be turned back to bring the flat side of its ends into alignment with the edge of the slots, thereby unlocking the legs, the rod ends being then in angular position to enter the slots and be slidable therein to permit the legs to be returned to folded position. This plate end, or finger-piece, extends at such an angle and. for
such distance from the rod that when it has been moved upward into engagement with the table top the rod ends are in the right angular position to enter the slots, the part of the table top engaged by the finger piece serving as a stop to limit the movement of the finger-piece.
In the modification'shown by Figs. 8, 9 and 10, instead of depending on the use of a spring rod which is put under torsional strain for effecting the locking movement of the rod ends when the legs reach their extended position, a cross-bar 3|! connecting the upper ends of the legs carries a leaf spring 3| which bears against a lug or shoulder on the pivot rod 20a, such lug being formed, as shown, by one end of a plate 21a. welded to the rod. As the upper ends of the legs move inward when the legs are being swung out to extended position, the spring 3| is put under tension so that when the ends of the rod come to the enlarged ends of the slots the rod is turned by the spring to effect the locking of the legs as before. As shown in this figure, also, the rod ends are flattened on their upper side instead of on the lower side as in Figs. 1 to 7, and the enlargement at the inner end of the slots is not of complete circular form, so that, the reduced end portions of the rod being suitably short, the angle bars l6 serve to prevent endwise movement of the rod out of position after assembly, and the spacing washers 26 are not depended on for this purpose andmay have cir- 5b. The locking enlargements are at the outer end of the slots, that is, the end toward the leg I pivots, and as shown are not circular but of a form such as shown in Fig. 10, so that the unreduced portions of the rod cannot pass through them. The flattened portion of the rod end shown is made by milling or otherwise forming a slot in the rod, leaving unreduced the end portion extending beyond the flattened portion. This extending end has welded thereon a plate (i0. By pressing on one or the other ends of this v plate M, the rod may be given the necessary turning movement for locking and unlocking the legs when they are in extended position and the rod ends in the locking enlargements of the slots l'lb. Such an operating plate might obviously be applied to the other end of the rod, also, and in such case these plates will serve to prevent endwise movement of the rod out of position, one of the plates being welded to the rod end after assembly. For convenience in assembly when 1;
the locking enlargements of the slots I'Ib. are, as shown, not of a size or shape to permit the unreduced portions of therod to pass, the slots I'Ib may be extended at their other ends for a distance beyond the path of travel of the ends of the locking rod and provided in such extended portion with an enlargement 4| of sufficient size to permit the unreduced portions of the rod to pass through. y
