The Vinvention contemplates leg bracing` means comprising a guide on the topsup-f porting frame providedwith ai longitudinal 0o groove extending inwardlyfrom one side? face thereof, and=an inner longitudinalre-iy taining channelextending V,at an angleto and adjoining said-groove, and a transverse ly resilient brace rod having Aawpivotalfcon# nection at one end with a leg, and havingat its otherend a lateralmextension provided Witha retainingoffset. end part or head, saidr lateral extension andioffset endpart or head slidably engaging respectively '1 `in said` 7o groove and channel, `and said guiderhaving` an opening leading laterally frornthe outer side of the guide to theretaining channel providing for the disengagement of the lateral extension and1ofsetendipart or head 76 from the groove and channel WhenA the leg -is moved to "bring said parts opposite. said. opening, the construction operating `to posi` tively holder retain the lateral extension of the bracein engagementwith theegroovel against 4accidental f displacement for :the major part of the opening and closingmove ments of the-leg While permitting Yof the i ready disengagement of the same manually;

therefrom. More particularlythe invention comprehends a construction of the character outlined, in which the lateral opening in the guide is located near one end thereofso that the offset end partor head of the later-allez;-A tension of the brace is disposed `opposite the opening in the guide Awhen the leg is moved to nearly closed position, the' #leg extending at an angle to the adjacent-,side `bar of the frameA so that the same does not interfere withl the grasping of the end of thebrace by the `fingers and `its movement laterally to dsengage the same' from andengage `the same with the groove and retaining channel;v While' a specific `embodiment of the `inventionisillustrated inthedrawings, Ait will 10o of courserbe understood that changes and obviousV modifications of the uparticular con` struction shown, and the embodiment of the invention in other forms, as will appeal to those skilled in the art, and fallingwvithin thescope of the appended claims, may he practiced without departing from the spirit of the invention.

Referring to a detail description ol the particular embodiment of the invention illustrated in the drawings, the top supporting iframev is shown square shape compo'ed of bars 1 suitably'secured together at their ends. 2 designates a relatively light thin top of paperboard or other suitable material, and' 3 is a cover of leather-ette, telt or like material stretched over t-he top 2 and having its marginal portions brought down over the sides otI the 'trame and held in place by the inishing strip t. 5 designates the legs pivotally connected to the support-ing i'rame at the corner portions thereoif to fold within the same along side the side bars 1, and 6 designates the braces for the legs, each brace being pivotally connected at one end to one of the legs and having a pivotal sliding' connection at its other end with one of t-he bars 1 otl the supporting Y frame. In the particular construction shown, the legs are pivotally mounted direct-ly against the inner sides ot the trame, and

the bars 1 of the i'rame are provided with longitudinally extending recesses 7 to accommodate the braces. In the mounting of the legs, brackets are employed, each bracket being shown in the form oit a metal strip having portions 8, 9, disposed at substantially right angles to each other, the portion 8 being rigidly secured flat against one oi the side bars 1 oi the trame, and the portion 9 extending in parallel spaced relation with an end port-ion of one of the bars. The legs are positioned between the portions 9 ot the brackets and t-he side bars 1 ol the 'tra-me, thepivotal connection being made by screws 10 passing through the bracket portions 9 and the end portions otI the legs 5, and entering t-he. bars 1 of the trame. 11 designates reinforcing strips, which are secured to the top 2 at the underside thereof in any desired way, for inst-ance by gluing. rlhe braces 6 each consist ot' a spring rod having an inwardly olfset portion 7a at one end pivotally connected with one or' the legs 5, and having an outwardly projecting portion 8 at its opposite end adapted to engage a guide groove on the top supporting frame.

In accordance with the present invention the top supporting frame is provided with guides fortlie leg braces 6, each guide hav-V ing a longitudinal Igroove 12 orthe lateral extension-8 of the brace, and an inner longitudinal retaining channel 13 extending at right angles to and adjoining said groove 12, and the lateral extensions 8 oitl the braces are each provided with a retaining shouldered or offset end part 14 to slidably engage in the inner longitudinal channel 13 of the guide and cooperate therewith to maintain the lateral extensions 8 ot the braces in engagelnent with the guide grooves 12. The

width ot the guide groove 13 ot a size sntlicient to permit of the ready withdrawal from and insertion of the retaining shoulder or otlset end portion 11 of the lateral extension 8 of the brace into the inner channel 13 through said opening in order to adjust the spring tension of the brace or 'for other purposes. The opening 15 of the guide is located near one end portion ot the same so that the shouldered or olfset end part 14 of the lateral extension 8 of the brace will occupy a position opposite the opening 15 when the leg 5 has been moved to nearly closed posit-ion, as illustrated in Figure 5 of the drawings, and is disposed at an angle to t-he guide so that the 'same does not in terfere with the grasping ot' the'end ot the brace end by the lingers and the movement of the brace end laterally out oi or into engagement withtlie inner channel 13. In the particular exempliiication illustrated in the drawings, the lguides are formed by longitudina-l recesses 1G in the frame bars 1, and metal plates 17 secured to the trame bars 1 adjacent the recesses 16, said plates 17 projecting above the lower walls 16a of the recess 16 partially thereover and the upper edges of the plates 17 extending below the upper wall 16b ot' the recesses in spaced relation therewith. The retaining shouldered or offset end part 14 of each brace is conveniently lormed by recessing or slotting the lateral extension 8 at 8a at one side therco'tI intermediate its ends, as shown.

The inner channels 1 3 of the guides, near one end, are each provided .in the rear wall thereof with a recess 18 adapted to receive and retain the outer end oi the lateral projecting port-ion 8 of the bracewhen the leg is moved to its untolded position, the end of the outwardly projecting portion 8 springing into the recess 18 at the end ol'I the opening movement of the leg. The plates 17 extend well beyond the location ot the recess 18 along the inner channels 13, said plates 17 serving as stops to limit the outward movement of the lateral extensions 8 of the braces in disengaging the same from said recesses. y

rI`he braces, which are constructed ofl spring wire, and which may be slightly' bent or bowed, as shown, are so adjusted that, through their transverse resiliency, they function to hold the legs in folded position with the free end portions of the legs pressed against the outer ends of thercinforcing strips 11, and to hold the legs iirm and rigid when in open position, taking up any lost motion due to possible looseness in the connection of the legs to the supporting frame.

It will be noted that by the special construction and arrangelnent "of 'parts hemiif before described, leg bracing fineansffof *a of the opening and closing inovernents'of the legs, and, which at the same time` permits` of the ready disengagement or manual withdrawal' ofthe brace *end from the guide groove for the purpose of adjusting the spring tension of the brace rod or for other purposes. It will also be noted that the guide with the inner retaining 'channel not only functions as retaining means to maintain the brace end in engagement with the guide groove, but also to limit the outward movement of the brace end in disengaging the same from the retaining recess 18, the outer wall of the inner channel serving as a stop for this purpose.

Subject matter disclosed but not claimed in this applica-tion is claimed in my application Serial No. 537,008, filed February 16, 1922.
