COLLAPS IBLE CHAIR Original Filed Sept. 21, 1928 Patented Mar. 10, 1931 UNITED STATES JAMES C. 'W. WALKER, OF ST. LOUIS, MICHIGAN COLLAPSLBLE CHAIR Application filed September 21, 1928, Serial No. 307,878. R enewed July 21, 1930.

This invention relates to folding chairs, and particularly to a chair in which the back and seat are formed of a woven fabric which is connected to a pair of relatively movable side frames, so that these side frames may be folded into parallel relation.

T he prime object of the invention is to provide slidable means on the seat rail to permit the chair to be folded, and which-will not rub against and wear the varnish or other finish from the leg stiles as the chair is being folded and unfolded.

Another object is to provide a foldable chair of neat and pleasing design, which will be easy and restful to the occupant, and rigid and substantial when set up for use.

With the above and other objects in view, the present invention consists in the combination and arrangement of parts, hereinafter more fully described, illustrated in the accompanying drawing, and particularly pointed out in the appended claims, it being understood that changes may be made in the form, size, proportion and minor. details of 2 construction, without departing from the spirit, or sacrificing any of the advantages of the invention.

In the drawing: v

Fig. 1 is a perspective view of a foldable to chair embodying my invention.

Fig. 2 is a front view showing the chair folded.

Fig. 3 is an enlarged fragmentary sectional view of the grooved stile and seat rail with a rider plate attached thereto.

Fig. 4 is also an enlarged fragmentary top plan view showing the leg stile, rider plate and seat rail.

Fig. 5 is an enlarged fragmentary side view of the back construction.

Referring now particularly to the drawing in which I have shown the preferred embodiment of my invention, the chair comprises right and left hand'frames, the left 50 the frame, both frames are formed identically hand frame comprising front and rear leg gether.

An arm rest 10 is rigidly secured to and connects the upper ends of the stiles, projecting beyond the rear leg stile for a purpose to be presently explained.

A seat rail 11 is slidably connected to the front and rear stiles as shown, and includes a pair of rider plates 12 which are pivotally connected to the ends of the rail by means of bolts 13, said plates being oppositely flanged as shown at 14, the end of the flange being turned inwardly to form legs 15 which engage and ride in the grooves 16 and 17 provided in the leg stiles, and I wish to direct particular attention to the fact that the inner surface or walls of these rider plates, do not come in contact with the finished surface of the stiles, as the legs 15 which ride in the grooves 16 and 17 ,definitely space the body of the plate from the surface of the stile. Consequently there is no scraping or marring of the chair finish as occurs where the rider plates slide on the stile proper. This is an important feature due to the fact that chairs of this design are folded and unfolded a great number of times.

The seat comprises a flexible fabric 18 I which is secured to the seat rails by means of tacking, sewing, or in any other approved manner.

In order to provide a tilt for the back without shaping the rear leg stiles, I provide a short extension member 19 which I secure to the end of the arm rest and the back of the rear leg stile, strips of flexible back fabric 20 and 21 being secured thereto. This makes a very economical, construction, which is of pleasing appearance, as well as providing the desired back inclination.

The lower rung 7 is rotatably connected to the leg stile by means of the bolt 22 and trellis bars 23 and 24 are rigidly connected to the rungs 7 and seat rails 11 respectively, said trellis bars being pivotally connected together by means of a bolt 25 in the usual manner. a

The lower end of the grooves 16 and 17 provide a definite and positive stop, and pretively movable side frames, each having a vent spreading of the side frames, and the grooves are of sufiicient length to permit the chair to be tightly and compactly folded.

From the foregoing descri tion it will be obvious that I have perfecte a very simple economical, and substantial folding chair, which can be compactly folded, and which is of neat and pleasmgappearance What I claim is q 1.. A collapsible chair comprising relativel movable side frames each having a for: ward leg stile and a rearward leg stile, grooves in the side walls of said stiles, seat rails interposed between the front and rear leg stiles and having rider plates mounted on the ends thereof, said plates being U-shaped and having inwardly projecting legs, which are slidably mounted in said grooves, and foldable trellis bars connecting said side frames.

2. A collapsible chair comprising relaforward leg stile and a rearward leg stile, grooves in the side Walls of said stiles, seat rails, rider plates pivotally mounted on the ends of said seat rails and provided with inwardly turned legs engaging in said grooves, and foldable trellis bars connecting saidside frames. v

In testimony whereof I hereunto afiix my signature.

JAMES C. W. WALKEB.
