CHAIR Filed Feb. 25, 1946 Patented Apr. 6, 1948 UNITED STATES PATENT OFFICE Application February 25. 194s, Serial No. 649,884

This invention relates to a chair construction. An object of the invention is to providea chair construction which is adapted to be made' of molded P wood.

A further object of my invention is to provide a 'chair construction which is not only adapted to be .made by a plywood molding process but is also adapted to be packed and shipped in 'a relatively small space and to be readily assembled at the place of sale or use.

A further object of the invention is to provide a chair construction which is durable, comfortable, inexpensive and strong.

In accordance with the invention the chair is made in two parts, one part constituting the seat s and legs of the chair and the other part constituting the back of the chair, each part heinl of such a shape that a plurality of units thereof may be nested for shipment or storage, and the two parts being designed for quick, easy and seany other suitable apparatus.

The chair structure is illustrated in the accompanying drawings in which Fig. 1 is a front elevational view oi the chair;

Fig. 218 a side view of the chair, Fig.3isarearviewofthechair.

Fig. 4 is a toprview of the chair with the seat and back portions separated, and

Fig. 5 is a fragmentary vertical section of the a cl im. (01. 155-193) V 2 i ing a plurality of the seat and legs sections and a plurality of the back sections. To this end the front and rear legs diverge away from the seat sufiiciently to permit one seat and legs section to be nested in another seat and legs section and the angle formed ,by the parts 4 and ii of the back section B are at an angle to each other of at least 90. The part I of the back section B preferably flts snu y in the slot 0 but this is not essential. The parts are of course made sufliciently strong. Plywood of 5 to 9 piles and from 1b to V4 inch in thickness gives a very strong vand durable chair as will be well understood by-one' having a knowledge of plywood structures.-

' It will be noted that the method of securing the backsectionBtotheseatandlegssectionA is very simple favoring quick assembly. Relatively little strain is applied to the fastening means 1-0. When the chair is tilted forward by taking hold ofthe back only a few pounds force is applied to the bolt I and its fastening to the chair seat whereas when a person sitting on the chair applies pressure to the back the strain is taken by the part I pressing upwardly against the bottom of the seat and by the back pressing downwardly against the lower wall of the slot 8. The bolt I may therefore be sumciently securely attached to the seat, e. g. by means of a relatively small plate and several small, e; g. half inch.

2.0 screws.

I claim:

L-A plywood chair construction comprising a unitary seat and legs section and a unitary back section, said back section having a forward exll tensionatitslowerendaslotintheseatand leg section adiacent therear boundary of the seat adapted to receive said forward extension. and means for securing said forward extension to the under side of the seat.

chair showing the means for securing the back 40 2. A chair-construction as defined in claim 1 in p section to the seat and legs section.

Referring to thedrawings, A is the seat and legs section of the chair and B the hack section. The seat and leg sectionli consists of thefront legs i, I. and the rear legs 2, 2 molded in a uni tary structure with the intermediate seat 2. It will be appreciated that the seat and less may be given any desired configuration or design, that shown in the drawings being merely illustrative. The back section 3 consists of the suitably shaped back 4 and the forwardly pr iocting ,partlwhlchisadaptedtoextendthroughthe. slot 8 in the seat and leg section and to he se cured to the seat by any suitable means such as maybemadeinsuchahapesastofacilitatenestgo 520,405

which the front and rearlegs diverge away from the seat and imwhich the forward extension of the back section is at an angle to the remainder fileofthispatent:
