This invention relates to improvements'in foldable furniture such as cots.

In foldable cots constructed heretofore and comprising, in general, afcanvastop sewed to a frameconsisting of side members or bars towhich the top is secured andtwo or more pairs of legs which are crossed and pivotally connected at" a pointintermediate their respective ends, the upper ends of the legs have been pivotally connected to the ends of the side members whereby thelegs may be folded together and then folded against the side members. In these cots,

which have forthe most part been made of wood, ithas been necessary to provide brac-i ing means at the joints between the legs and side membersto give the cot sufiicient rigidity and to hold the same open for use. i It has been necessary to so construct these bracing means or members so that the same are also foldable so as not to interfere with the folding together of the legs and theside members in the manner referred to above, this construction interfering. more or less with the folding and unfolding of the cot frame, aswell as detracting from the general appearance of the cot and adding to the weight thereof. With the advent of the so-called all-metal cot, which is generally made from sheet-metal tubing of standard gauge, it has been a problem to provide means for pivotally connecting the legs to the side frame members and adequately brace the frame at these poin ts when thecot is'open for use without interfering with the folding and unfolding of the cot or adding to the weight thereof, or detracting fromthe appearance of the same.

/ One of the objects of the present'invention, therefore, is to provide an improved hinge for p'ivotally connecting the legs to the side frame members of'a' foldable cot of and 3, the cot compr1ses,-1n general, al gned, lsidemembers 1 and 2 pivotally connectedtogether ,attheir adjacent ends by means of a hinge 3, thehinge being fixed rigidly to the upper end of'a leg 4 crossinga similar leg 5 the character referred'tofand to construct the hinge so that-it is adapted to interlock with one of the connected parts in such manner'that the use of any supplementaryreinforcing or bracing members1s:unn.ecessary.

l of spaced arms fitted the latter will enter between the adjacent ends of side members 37 and socket portions L1, as more clearly shown in Fig. 7, the upper end of the leg having a relatively tight or snug fit between these parts to provide against any loose play or possible pivotal movement of the legs and side members with respect to each other about bolts 40, the latter engaging the lower ends of the slots when the upper ends of the legs are substantially flush with the upper edges of the socket portions, as more clearly shown in Fig. 6.

In this modified construction, the reinforcing members 31 in Fig. 1 are omitted and the canvas top extended, as shown in Fig. 7*, so that the adjacent ends of arms 35 of the hinges enter the ends of the pockets at the side edges of the top, one of the bolts 36 being passed through the top, as shown, whereby the corners of the top are fixedsecurely to the side frame members so that when the cot is open the top will be held taut at all times and prevented from sagging longitudinally.

From the foregoing it will be seen that the improved hinge construction performs the double function of pivotally connectingthe frame parts together and locking the same against pivotal movement with respect to each other when the cot is set up, the supplementary reinforcing members used heretofore for imparting rigidity to foldable cots of this type being dispensed with, the improved hinge construction thus providing for a cot of simpler construction, lighter weight I and neater appearance than those constructed heretofore.

The improved hinge has been shown and described in connection with a foldable cot, but of course the invention is of much broader adaptation and may be used with equal advantage in the construction of other articles of furniture of the folding type, such as chairs, tables and the like.

Several embodiments of the invention have been shown and described, but of course various changes in the size, shape and arrangement of the parts may be adopted without departing from the spirit of the invention or the scope of the claims.

Ihe invention claimed is:

1. A foldable article of furniture includ ing frame members and leg members and hinges between the frame members and the leg members, each hinge comprising a pair snugly against the associated frame member adjacent one end thereof, a pin and slot connection between said arms and said frame members, a second pair of arms integral with said first menioned arms and angularly positioned with respect thereto, said second pair of arms being snugly fitted against and fixedly secured to the associated leg member and a curved connecting piece and socket forming formed member integral w1th the arms and as a continuation of the second pair of arms, said connecting piece and socket forming member. providing'a socket adapted to receive and'hold the associated frame member frame member to pass and permit the through and extend beyond the socket when the article of furniture is set up whereby additional means maybe mounted on a portion of the frame member which passes through the socket.

2; In an article of furniture of the character described, side frame members, a pair of crossed legs pivotally connected intermediate their respective ends, hingemembers comprising bodyv portions secured to the upper ends of said legs and provided withsockets overhanging the same, spective adjacent ends of said side members extending through said sockets ends whereby said reinforcing member acts to hold said legs in spread-out, operative position and to prevent withdrawal of the extended ends of theside members from the sockets until said reinforcingmember is removed.

In witness whereof I hereto afiix my sig nature.
