United States Patent 3,275,375 CHAIR This invention relates to a chair, and has for its ob- 'jects the provision of a chair which will prove sturdy and durable in use, which can be economically constructed from metal tubing, which can be easily assembled, and which will be of attractive appearance.

Acconding to one form of the invention, there is provided a seat carried on a pair of cross members connected to a pair of side rails. The side rails are supported on a plurality of ground-engaging legs. The rear legs project upwardly above the seat and are connected at their upper ends by a transversely extending back support. A pair of mounting plates are connected to the back support in laterally spaced relationship and are adapted to receive fastening means connected to a back rest for supporting said back rest in an elevated position above the seat adjacent the rear thereof.

Other objects and features of the invention will become apparent from the more detailed description which follows and from the accompanying drawings, in which:

FIG. 1 is a side elevation of a chair embodying the invention;

FIG. 2 is a front elevation of the chair shown in FIG.

FIG. 3 is a plan view of the chair shown in FIG. 1 with portions thereof being broken away;

FIG. 4 is an enlarged transverse section taken on the line 44 of FIG. 1;

FIG. 5 is an enlarged transverse section taken on the line 55 of FIG. 1;

FIG. 6 is an enlarged horizontal section taken on the line 6-6 of FIG. 1;

FIG. 7 is a vertical section taken on the line 77 of FIG. 3;

FIG. 8 is a side elevation of a modified form of the invention;

FIG. 9 is a rear elevation of the chair shown in FIG. 8;

FIG. 10 is a side elevation of another modified form of the invention;

FIG. 11 is a rear elevation of the chair shown in FIG. 10;

FIG. 12 is a side elevation of another modified form of the invention; and

FIG. 13 is a rear elevation of the chair shown in FIG.

The chair illustrated in FIG. 1 of the drawings is supported adjacent its forward end by a pair of groundengaging front legs 10 conveniently formed of metal tubing and provided with end caps 11 at their lower ends. The rear portion of the chair is supported on a pair of ground-engaging rear legs 12 also formed of metal tubing and having their ends closed by end caps 13. The front and rear legs at each side of the chair are interconnected by a side rail 14. A pair of channeled cross members 16 identical in construction are connected to the side rails 14 in spaced fore and aft relation. As shown in FIG. 4, each of said cross members 16 has an apertured plug 18 fixedly mounted at each of its ends. Said plug supports a screw 19 projecting through an opening in the adjacent side rail 14 and received in a tapped plate 20 carried Within said side rail. Thus, upon drawing the screws 19 up in the plates 20, the cross members 16 and side rails 14 will be rigidly interconnected and the chair will be cross braced.

A seat 22 is carried on the cross members 16. Said seat comprises an upholstered upper portion 24 supported on a wooden panel 25. The seat is connected to the cross members by a plurality of screws 26 extending upwardly through the cross members and spacers 28 carried on the upper faces of said cross members with the upper ends of said screws being threadably received in tapped staples 30in the seat panel 25.

The rear legs .12 project upwardly above the seat 22 and are interconnected at their upper ends by a transversely extending arcuate brace 32 conveniently formed as a forwardly open channel. As shown in FIG. 6, a plug 34 is fixedly mounted in each end of the brace 32 and receives a screw 35 projecting outwardly from the end of the brace for reception in the adjacent rear leg 12 for rigidly interconnecting the brace 32 to the rear legs. A pair of vertically extending plates 37 are mounted on the forward face of the brace 32 in laterally spaced relationship. Each of the plates 37 is provided with a pair of forwardly dished recesses 38 which abut the rear face of'a-back rest 40 conveniently formed of a forward upholstered portion 42 mounted on a wooden panel 44. A screw 46 is carried-in each of the recesses 38 andprojects through an opening therein for reception in a tapped staple '47 mounted on the back rest panel 44. Thus, the screws 46 can be drawn up in the staples 47 for bindingly retaining the-back rest against the forwardly presented faces of the recesses 38 for mounting the back rest on the brace 32. Desirably, a pair of cover plates 39 are snap-fit on .each'of the plates 37 to cover the recesses 38 and the screws received therein.

In the chair illustrated in FIG. 1, the front legs project .upwardly above the seat 22, and the upper end of each -of said legs is interconnected to the adjacent rear leg 12 by an upwardly open channel 50. A plurality of screws 52 extend upwardly through the channel 50 and v are received in an arm-rest 54 for fixedly mounting said arm rest on theupper face of the channel 50 and the upper ends of the front and rear legs 10 and 12.

The embodiment of the chair illustrated in FIGS. .8- and 9 is identical in construction to the chair illustrated in FIG. 1 with the exception that the front legs 10 do not project above the seat 22, and said chair is not pro vided with arm rests. The front legs 10 in the chair shown in FIG. 8 are interconnected by side rails 14 to a pair of rear legs 12,with said side rails being interconnected by cross members 16 in the same manner as illustrated in FIG. 4. The seat 22 shown in FIG. 8 is of the same construction as the seat illustrated in FIG. 4 and is connected to .the cross members in the same manner as shown in FIG. 4.

In the chair illustrated in FIG. 8, the upper ends of the rear legs 12 are interconnected to the ends of the arcuate cross brace 32 in the manner shown in FIG. 6, and said cross member is provided with a pair of mount ing plates 37 connected to the rear face of the back rest 40 by screws 46 received in the plate recesses 38 as shown in FIG. 7.

FIGS. 10 and 11 show the invention of FIG. 1 embodied in a swivel type chair. In this embodiment, the seat 72 is supported on channeled cross members 66 connected to a pair of side rails 64 in the same manner as shown in FIG. 4. Rear leg members 62 project upwardly from the rear ends of the side rails 64 and are connected to an =arcuate back rest brace 82 in the same manner as illustrated in FIG. 6. The brace 82 has a pair of laterally spaced plates 87 mounted thereon which are connected by screws 96 carried in plate recesses 88 and received in the back rest 90 for fixedly mounting the said back rest on the brace.

The forward ends of the side rails 64 are connected to front, legs 60 which project upwardly from said side rail and have their upper ends connected to the upper ends of the rear legs 62 by upwardly open channels 110. Each of the channels 110 carries a plurality of screws 112 which are received in an arm rest 114 for mounting said arm rest on the upper face of the channel.

The lower ends of the front and rear legs 60 and 62 terminate at the side rails 64. Therefore, to suppor-tthe chair seat 72 in an elevated position,.said seat is mounted on any desired ground-engaging base 115, which can be conveniently in the form of a swivel base. 7 The chair illustrated in FIGS. 12 and 13 is like the chair illustrated in FIGS. and 11 except for the omission of the arm rest. As shown in FIG. 12, the seat 72 is supportedin an elevated position above the ground on a ground-engaging base 115. The seat is connected to a pair of transversely extending cross members 66 connected attheir ends to a pair of side rails 64 in'the manner shoWnin FIG. 4. A pair of rear legs 62 project :upwardly from the rear ends of the side rail 64 and are interconnected at their ends by a transversely ex- 'tending arcuate back rest brace 82 having a pair of mounting plates 87 mounted thereon in laterally spaced relationship. Screws 96 project through recesses 88 -in- -the-mounting plates and are received in the rear face of the back rest 90 for mounting said back rest on the frame 82. Since the side rails 64 are not connected to the front legs ,at their forward ends, the forward ends I of the side rails are desirably closed by end caps 116.
