1 Claim. 1

This invention relates to steel furniture and more particularly to chairs especially suitable as porch and lawn furniture.

The principal object of the invention is to provide a chair whose body supporting structure is fabricated from thin, highly flexible strips, preferably metal for durability, said strips being parallel and extend from an anchorage at the front edge of the seat to a point beyond their anchorage to the top of a comparatively high back frame. The back frame and seat frame are pivotally joined together and to these frames are connected pivotally a leg support and arm rests, the former consisting also of parallel, flexible strips. The supporting frame of the recited structure is detachably connected to the body supporting frame and the leg support and the entire arrangement, including an adjustable footrest constitutes a readily collapsible chair which, in assembly, comfortably supports the body in any position from prone to upright.

With the foregoing in view, the invention has further reference to other objects as well as certain features of accomplishment to become manifest as the description proceeds, taken in connection with the accompanying drawing wherein:

Figure 1 is a perspective view of the invention with the body supporting structure extended.

Figure 2 is a rear perspective view showing the body supporting structure upright, and

Figure 3 is a front perspective view of the chair in the position shown in Figure 2.

Continuing with a more detailed description of the drawing, reference numeral l denotes a supporting frame consisting of parallel, inverted U-shaped members, joined together by rods H but which latter are readily detachable by removing threaded nuts I2.

The upper end of each leg of the members I0 is slotted at a. The slots in the front legs are adapted to releasably receive headed pins bextending outwardly from the side members I3 which latter serve as the leg supporting frame by virtue of their pivotal attachment at c (Fig. 1) to the forward ends of parallel members M of the seat frame and their pivotal attachment at d to depending members I5 of arm rests it.

The leg supporting frame members 13 extend downwardly to support a foot rest I! which latter is adjustably mounted by means of arms l8 which are pivoted at e to the said members l3 and at f to a point intermediate the sides of the said foot rest 11. In this manner the foot rest may be disposed in a plane at right angles to the plane of the leg support, as shown in Figures 2 and 3; in a position parallel with but elevated above the said leg support, as shown in Figure l, or the said foot rest may be folded to the position shown in dotted lines in Fi ure 2.

The said seat frame members l4 are pivotally connected at g to the lower ends of members l9) constituting the side members of the back frame and the depending members 20 of the arm rests It, companion to the members l5 thereof are pivoted at h to a point on the back frame members IS. The described arrangement constitutes; virtually a parallelogram with pivotal points at c, d, g and h. Accordingly, as the leg support is lowered the back frame is raised in equal degree, with corresponding movement of the arm rests Hi.

It is obvious that as the back and leg rest are adjusted to the reclining position shown in Figure 1, the seat frame is advanced and is retracted when the back and leg rest are moved to upright position exemplified in the other figures of the drawing. This contributed to a well balanced construction, automatically compensating for the shifting of a part of the weight of the body in reclining position slightly rearwardly of the supporting frame. In this manner stability and comfort is obtained.

Connected to a rail 2| at the forward edge of the seat frame and extending rearwardly and upwardly along the back frame are thin, preferably metal strips 22. These strips are supported transversely by means of a strap 23 (Figs. 2 and 3), situated at a point at an approximate level with the arm rests l6 when in the position shown in Figure 2 and 3, and extend from one to the other of the back frame members l9. A strap 23a similar to strap 23 extends transversely across the seat frame from one member M to the other.

Strips '24 of a similar construction are anchored to a cross member 25, extending from one to the other of leg supporting frame members l3 and the opposite or lower ends of the strips are anchored to an end member 26 (Fig. 1) of the leg supporting frame.

As a protection against any possibility that garments may be caught between the forward legs of the supporting frame l0 and the leg supporting frame members IS, a plate 21 is affixed to the latter at each side of the seat frame.

It is apparent from the foregoing that in order to disassemble the chair for shipment or storage, the reinforcing rods I I may first be removed whereupon the upper ends of the legs of supporting frame 10 are compressed to release their slots at from pins 1) to detach them from the back and leg supporting frames. By detaching the arm rests from the back frame by removing pivot pins h and releasing the leg supporting frame from the seat frame by removing pivot pins 0, the arm rests may be folded onto the leg support as a separate unit while the back may be folded onto the seat frame, the strips 22, by virtue of the flexibility permitting this operation. A package of compact proportions results, and bulkiness in shipping or storage is reduced.

Manifestly, the construction as shown and described is capable of some modification and such modification as may be construed to fall within the scope and meaning of the appended claim is also considered to be within the spirit and intent of the invention.

What is claimed is:

A chair comprising a base frame consisting of a pair of flexible and relatively spaced U-shaped members defining legs having opposed horizontal slots in their upper ends extending to the edge of said members, a seat frame and a back frame, a leg supporting frame, means carried by said back frame and leg supporting frame and pivotally received in the slots of said legs to swingably support said seat, back and leg supporting REFERENCES CITED I'he following references are of record in the file of this patent:
