FOLDABLE CHAIR Filed Sept; 28, 1937 l i :i Invervztor 6' 3 f /6 0 Wageff UyP/"S Attorneys Patented Feb. 21, 1939 UNITED STATES PATENT oFFlcE 1 Claim.

The present invention relates to a novel portable type folding or collapsible chair for individual use and has more specific reference to a structure adequately adaptable for use in comfortably accommodating the occupant when used in athletic stadiums and the like.

My primary aim is to generally improve upon collapsible seat structures of this particular subdivision by providing a simple and reliable construction susceptible of satisfactory usage when placed on wooden and concrete foundations.

In reducing to practice the principles of the inventive idea, I found it exceedingly practicable to utilize companion metal frames, these being hingedly attached together and provided with cushions, and being perfected to guard against slipping and to maintain the back rest in a yieldable self-accommodating position.

Other features and advantages will become more readily apparent from the following description and accompanying illustrative drawing.

In the drawing:

Figure l is a front elevational View, partly in perspective, showing a structure perfected in accordance with the preferred embodiment of the invention.

Figure 2 is an edge View, showing in dotted lines, how the back rest may be collapsed for compactness and convenience to facilitate carrying.

As before implied the structure is made up primarily of two companion units, that is the seat unit 3 and the back rest unit 4. The seat unit 3 comprises a part circular frame 5 fashioned from durable wire or a heavy metal rod of, appropriate bendable rigidity. The frontal portion of the frame is bent down at right angles as at 5 to form a retention lip or detent and this facilitates holding the structure against a slippage in a rearward direction in relation to the foundation on which it is removably placed. Inwardly of the depending lip G are relatively short integral studs 'l which constitute tilting as well as antislipping feet. The rear portion of the frame is provided with parallel extensions or arms 8 terminating in eyes 9 to accommodate the hinge pin IB. p

The sectional unit 4 also comprises a substantially circular metal frame li and this has armlike extensions or limbs i2 terminating in eyes I3 hingedly attached to the hinging and assembling pin l0. The numerals ill and l5 designate appropriately padded cushions having their marginal portions laced as at i6 to the frames. The

cushions are confined within the limits of the respective frames and preferably constructed of inexpensive material such as may be painted or otherwise finished for advertising purposes.

I next call attention to coiled springs I 'l attached to the frame 5 within the vicinity of the hinged connection. As seen in Figure 2 the coiled springs are provided with hooks I8 releasably engageable with snap fasteners I9 held by portions of the frame ll. Thus the snap fasteners and springs serve to support the unit 4 in a back rest forming position and the arrangement is such as to render said unit accommodating to rearward pressure. Emphasis is attached to the use of simple inexpensive metal frames partcircular in form having extensions disposed in parallelism and terminating in eyes to facilitate accommodation of the pins Il). Thus when the two parts are folded in superposed relationship as seen in Figure 2 the pin It functions as a handle to facilitate transportation.

Novelty also resides, itappears, in the use of this simple hinged frame connection with the equally simple padded cushion and the releasable spring means serving to maintain the back rest unit 4 in a desired tilted effectively usable position.

It is to be pointed out that the structure herein observed lends itself admirably well to use as va seat in a boat. When employed in conjunction with row-boats and the like it has been found expedient and practicable to construct the cushions so that they are in effect inflated bags. The purpose in doing this is to afford comfort and to simultaneously enable the device to be satisfactorily employed as a life preserver.

It is` thought that the description taken in connection with the drawing will enable a clear understanding of the invention to be had. Therefore, a more lengthy description is thought unnecessary.

While the preferred embodiment of the invention has been shown and described, it is to be understood that minor changes coming Within the field of invention claimed may be resorted to if desired.

I claim:

.A portable and foldable chair of the class described comprising a seat part including a frame having outwardly bowed side portions, rearwardly extending parallel parts connected to the rear ends of said side portions, and a substantially U-shaped part at the front of said frame including a substantially straight and elongated bight, and upwardly extending limbs connected with the front ends of the side portions of the frame, a back forming frame of substantially circular shape but having spaced and outwardly extending parallel ends which fit between the ends of the parallel parts of the seat frame, a pivot pin passing through the ends of the parallel parts ofy the seat frame and said parallel ends of the back frame pivoting the back frame to the seat frame, springs connected with the side portions of the seat frame and those portions of the back frame which are located adjacent the parallel ends of said frame, said springs limiting rearward movement of the back frame and legs depending from the forward portions of the side parts of the seat frame and said legs being shorter than the limbs of the U-shaped part at the front of the seat frame.
