Claims. (Cl. 155-439) This invention relates to a folding chair.

It is an object of this invention to provide a folding chair which is comfortable for seating and can be easily folded into a compact form or unfolded in one simple motion.

Another object is to provide a folding chair which is sturdy and attractive and the chair frame can be constructed from one type of stock material.

Another object is to provide a folding chair wherein no disassembly of the chair frame or removal of the chair canvas fabric is required prior to folding.

A further object is to provide a folding chair which is generally an improvement over previously known folding chairs.

Other objects and advantages Will become apparent upon reading the following description in conjunction with the accompanying drawings, wherein:

Fig. l is a rear perspective view of a preferred embodiment of the chair of this invention with the fabric shown broken away in two places.

Fig. 2 is a slightly reduced sectional view taken on the plane defined by the line 22 of Fig. 1.

Fig. 3 is a rear perspective view of the chair of Fig. 1 but with the chair in the folded position.

The same reference numerals refer to the same part throughout the several views.

The drawings show a folding chair including a pair of front legs shown disposed at a reclining angle when the chair is fully unfolded, as shown in Fig.- 1. Two cross-pieces 11 and 12 are suitably attached at their opposite ends to the legs 10, as shown, 'to' brace the legs in the fixed spaced apart position shown. Intermediate portions of both of the legs 10 are pivotally attached by pins 13 to cross-members 14 which extend from the legs substantially horizontal to the rear of the chair. Similarly, arm rests 16, which also constitute cross-members, are pivotally attached to the upper ends of the legs 10 by pins 17, and the rests 16 extend to the rear of the chair. A back rest frame 18 is pivotally attached to the rear ends of the members 14 and 16 by pins 19 and 21, respectively. The frame 18 is composed of side members or rails 22 and upper and lower cross-members 23 and 24, respectively.

It should be noted that the members 14 and 16 both extend rearward of the back frame 18 for purposes described later. Also, the members 14 and 16 and the legs 10 and the back frame 18 are all disposed to form a parallelogram, which is best shown in Fig. 2 and is defined by the pins 13, 17, 19, and 21. The members thus described form a main frame of the chair and the frame is disposed at the reclining angle of the front legs 10.

The rearward ends of the members 14 have a pair of rear legs 26 pivotally attached thereto by pins 27. Crosspieces 28 are suitably attached between the legs 26 to secure them spaced apart a distance equal to the spacing of the front legs 10. The legs 26 are normally disposed at an inclining angle, in the fully unfolded position of 2,783,825 Patented Mar. 5, 1957 'ice Fig. 1, which angle is opposite to the reclining angle of the back frame 18. Thus, the legs 26 are arranged to abut the rear side of the frame 18 at the upperends 29 of the legs 26. A pair of braces or links 31 is pivotally attached by pins 32 to the sides 22 of the frame 18 to extend upwardly to the upper end of the legs and be pivotally attached thereto by pins 33. v

With this arrangement, the fronta'n'd rear legs are disposed on the insides of the members 14 and 16 with the rear ends of the members 16 and the upper ends of the legs 26 being immediately adjacent each other as the members 16 extend beyond the frame 18, and the legs 26 abut the frame at the plane of that extension. The members 16 and the legs 26 are thus disposed tolend mutual lateral support to each other and thereby make the entire chair a sturdy structure.

Particularly Fig. 2 shows a canvas fabric 34 attached to the cross piece 11 at the front legs 10 and to the crosspiece 23 of the back frame 18. The fabric is preferably tacked at the attachment places mentioned but the intermediate portion thereof is shown to be movablyanchored to the cross-piece 24 by a piece 36 of the fabric formed into a loop around the member 24 and sewed to the fabric 34. In this manner, the fabric 34"is taut and forms a horizontal seat portion 37 and a reclined back portion 38 with the entire fabric 34 being attached" in the nature of a hammock since it is secured atits two ends only. It shouldv also be noted that the fabric34 is formed with a wide hem defined. by the line"39"on each side of the fabric and extended along the entire length of the fabric. Since 'thefabric is thus doubled at both of its sides, the weight of the user is distributed from the fabric to the members 11, 24, and 23, due to the strong fabric arrangement.

The chair can thus be 'compactly and easily folded to the position shown in Fig. 3. The upper part ofthe back frame 18 can be pivoted down onto the seat of the chair while the foot of the person folding the chair can be placed in front of one of the legs 10 to hold the frame in position. The parallelogram feature permits the main frame to be folded while thebraces 31'permit the rear legs to fold compactly with the main frame, 'as is obvious from the drawings. In folding the chair, it will be noted that the fabric 34 is also taut in the folded position since the mid-portion of the fabric is anchored a distance from the pivot pin 19 substantially equal to the distance of the fabric front end from the pivot pin 13. The cross: piece 11 rolls' the fabrica slight distance'upon the piece 11 in the folding movement and the fabric is assured of its tautness in the folded position. Also, the fabric need not be removed or loosened on the chair prior to folding the chair.

While a specific embodiment of this invention has been shown and described, it should be obvious that certain changes could be made therein without departing from the invention which should, therefore, be limited only by the scope of the appended claims.

We claim:
