roLnAnLn CAMP CHAIR.

Application filed January 19, 1926. Serial No. 82,204.

invention is a folding canip chair of the type having folding back and a fabric seat. 1

nn object of my invention is the construction of a folding camp chair having a fold ing back, adapted to fold closely against the folded legs of the chair when the chair is in folded position and having braces to hold the back infolded position and to support the back when the chair is extendedor unfolded for use.

Another object of my invention is to utilise orossrods as strengtheners which also are utilized to take the stressesdirectly coming on the canvas seat.

In my canip chair I utilize folding legs of substantially the ordinary type; a folding back is hingedtothe upper ends of. a pair of legs; a diagonal brace is connected between thebaclt andon'e of, the legs, being detachable from the leg, the back is arranged to hinge forwardly so that when the legs are folded together, the back folds down over the legs and the brace swivelled into a reverse position in regard to the back, and engaging the legs to hold the back and legs clamped firmly in a folded position.

My invention will be more readily understood from the following description and drawings in which:

Figure 1 is a perspective view of my camp chair.

2 a front elevation of the chair taken in the direction of the arrow 2 of Fig. 3.

Fig. 2) is a side view of the chair taken in the direction of the arrow 3 of Fig. 2.

Fig. 4- is a vertical section on the line l -f of Fig. 2.

Fig. 5 is a front View of the folded chair en in the direction of the arrow 5 of Fin. 6.

en in the direction of the arrow 6 of Fig. 6 is an edge view of the folded chair end of theside poststi ofthe back 7 these posts being connected to the legs 1 by hinges 8. The posts of the back are joined by an. upper barO and a metal bar 10.

A seat 11 is fori ned by an upper and lower strip of canvas 12 and 13; This canvas is preferably secured to a cross rod 1 1 out square on the baclrto rest against the upper ends of the inner legs 2, passing around a slat 15 which is secured to the upper ends of the outer legs 1. This slat is notched at each end soas toe ztend outwardly over the legs 1 as indicated by the numeral 16 and to extend partly inwardly of said logs; the inner edge of the slat fitting close against a cross rod 17 which is riveted-to the upper parts of thelegs l. A cross rod 18 is also connected between the upper ends of the legs 2 behind the cross rodl i. The canvas of the seat passes over the curved edge of the cross rod 14, loops over the slat 15 and the rod 1? and extends upwardly over the rod 18 between said rod and the cross rod i i.

The back is braced to the legs by a pair of braces 19 which at their upper ends are swivelled to the side posts 6 by pivot pins 20. These braces have hooks 21 formed at their other end adapted to engage over pins 22 in the legs 1 to hold the side posts and hence the back in the proper position when extended, as clearly indicated in Figs. 1, 3 and 4.

Additional cross bracing of the legs is provided by the cross slat 23 between the lower ends of the legs 1 and the rod 24: be tween the lower ends of the inner legs Y'Vhen it is desired to fold the chair, the. braces 19 are unhooked from the pins 22, the legs are pressed together so that the seat droops down between the legs, the back is hinged forwardly over the legs, hanging down into the position shown in ii 6, and the braces 19 are swivelled on the pins 20 into a reverse position so that the hooks may engage pins on the lower ends of the legs 1; thus securely clamping the back in its downwardly folded position and preventing the legs from folding.

My form of braced back may be used with a type of chair having a rigid seat such as a wooden seat, pivoted to either set of the legs and adapted to hang downwardly when the chair is folded, the braces 19 holding the back in the proper position for use and the hack and legs clamped together when folded.

1 preferably use a jointed cross brace 26 secured to the upper end of the legs 1 and 2 by means of pins or the like and havinga.

, In Fig. 7 the brace 28 connecting the side posts 6 and the legs 1 is jointed, having a connecting pin 29 between the upper and lower section of the brace and having both ends of the brace secured to pins 30. In this type of brace a person sittingback on the chair forces the brace into proper position.

It will'thus be seen that although my chair is of a simple design, nevertheless'the construction may be considerably changed in general features and specificdetails to adapt it to different styles of chairs. Such changes would be within the spirit of my invention as set forth in the description, drawings and claims.

Having described my invention, What I claim is: V 1. A folding camp chair comprising in combination outer and inner legs crossed over each other and pivoted together, a back having side posts pivotally connected to the upper ends of the outer legs, a pair of braces pivotally connected to the side posts and havinghooked ends, pins on the outer legs to cooperate with the said hooks, and a second set of pins adjacent the lower ends of the outer'legs to engage the brace bars when the back and legs are folded.

'2. A folding camp chair comprising in combination outer and inner legs crossed over each other and pivoted together, aback hinged to one set of legs, a slat connecting said legs adjacent the hinge, a metal rod secured between the said legs immediately behind the said slat, a cross rod connecting the upper ends of the other legs, a seat formed of fabric encircling the said cross rod, the slat and the metal rod, braces pivotally connected to the back, pins on the legs to which the back is hinged, hooks on the braces adapted to engage said pins to support the hackin extended position, and a second set of pins adjacent the lower ends of the legs to which the back is hinged, adapted to engage the brace to hold the-seat and the legs in folded position. 7' i In testimony whereof I have signed my name to this specification.
