Description:

This invention relates to knock-down arm chairs capable of ready assembly. It has for its principal object to provide such devices in which the seat or the seat and the back are made as separate units, for assembly with side frame mem- -5 bers by peg and socket connections.

It has for a further object to provide, in such assemblies, the side frame members with additional projections to act as further supports for the seat or the seat and the back. 10. In general, according to the invention, the seat or the seat and the back, which are formed as separate units, comprise projecting pegs adapted to fit into sockets in the side frame members, the said side frame members also carrying projections 15, to form additional supports for the seat, and if desired, for the back.

Thus arm chairs constructed according to the invention, when knocked-down comprise four substantially flat parts capable of being readily transported or stored and occupying a minimum bulk. Further the four units for such an arm chair can readily be fitted together to give a stable and comfortable structure.

In order that the invention may be better understood, it will now be described with reference to the accompanying drawings in which one embodiment of an arm chair, constructed according to the invention, is represented somewhat diagrammatically. In the drawings: Fig. 1 shows a perspective view of the assembled arm chair with a portion broken away to more clearly show the structure.

Fig. 2 is a side elevation thereof and Fig. 3 shows in elevation on a larger scale, a structural fragment of the juncture of a part of the back portion with a part of one of the main side frames.

Referring now, more particularly, to the accompanying drawings there is provided an arm chair which comprises two substantially rectangular main side frames, each comprising in turn a base or foot portion I merging into front and rear upright portions 2 and 2' respectively, the former being joined to the latter by a top portion I' which is substantially parallel to the foot portion and constitutes an arm rest, said top portion being joined at a point short of the upper end of the rear upright portion as shown in Fig. 2. Each side frame additionally carries a substantially U-shaped bracing member 5 fixed at its upper ends to the front and rear upright portions 2, 2' substantially medially of the height thereof. The upper end of the front portion of each bracing member 5 is formed as a socket while the rear end carries an inwardly extending projection 6 which is positioned in opposed relation to the projection 6 on the other side frame.

Preferably each side frame is formed of a single piece of tubular metal.

The seat 3 preferably is formed from metal tubing and comprises a frame of substantially rectangular configuration carrying any desired form of seating surface proper, for example, woven or plaited cane or other material. The seat is detachably connected to the main side frames by pegs 7 which depend from the downwardly turned front portion of the seat and engage in the sockets at the upper front ends of the bracing members 5 as illustrated clearly in Figs. 1 and 2.

The rear portion of the seat as also shown in these figures is slightly curved and rests on the inwardly extending projections 6.

The back 4 may be constructed similarly to the seat, that is to say, it may consist of a frame preferably of rectangular configuration and formed of tubular metal and a back proper of woven or plaited cane or other material. The back frame is formed with elongated pegs 8 and 9 preferably in the form of continuations of the sides of the said frame. These pegs 8 and 9 in the assembled condition of the chair are inserted into the apertures in elongated socket members 10 formed with or fixed to the rear upright portions 2' of the main side frames so that the back frame is positioned between the upper portions of the rear uprights of the main side frames as clearly shown in the drawings.

As will be appreciated, in place of the diagrammatic structure illustrated in the drawings, the chair may be constructed in an ornamental manner, and the finish given to the framework which may be metal tubes, can be of any coloured paint or otherwise, or they may be chromium plated.

Again, instead of plaited or woven cane for the seat or back, there may be provided seating and back surfaces of other construction, for example these may be smooth surfaces and formed from wood, metal or of any other suitable material. Again they may be upholstered and comprise a resilient or other under layer as desired and known in the furniture art.

Although the invention has been specifically described as relating to arm chairs, somewhat similar constructions may also be employed for tables.

What I claim and desire to secure by Letters Patent of the United States of America is: 1. A knock-down arm chair comprising two main rectangular side supporting frames, each of which consists of a single piece of metal tube bent to form a foot portion, front and rear upright portions continuing therefrom, a top portion extending from the front portion and joined to the rear portion near the top to constitute an arm rest, sockets carried by the front and rear upright portions medially of the height thereof, opposed horizontal projections on said side frames near the rear thereof, a rectangular seat frame having its front portion bent downwardly and provided with two downwardly extending pegs to detachably engage the sockets in the upright front portions, the inner end of the seat frame being supported on said horizontal projections, and a substantially rectangular back frame having downwardly extending elongated pegs at the lower ends of the side portions thereof for detachable engagement with the two sockets at the rear of the side frames, a U-shaped member secured to the front and rear upright portion of each of the side frames, and the front sockets being formed in the front ends of said bracing members.

2. A knock-down arm chair comprising two main side frames, each formed from a single piece of tubular metal and comprising a foot portion, front and rear upright portions continuing therefrom, top portions extending from the front upright portions and joined to the rear upright portions adjacent the upper end so as to provide arm rests, U-shaped bracing members for each side frame, the end portions of the bracing members being fixed substantially medially of the heights of the upright portions, the front ends of said U-shaped bracing members having sockets therein, horizontal pegs extending inwardly from the rear ends of the bracing members, other sockets on the rear upright portions substantially medially of the height thereof, a seat frame of substantially rectangular configuration and formed of tubular metal having a downwardly turned front portion terminating in pegs for detachable engagement with the sockets in the front ends of the bracing members, the rear portion of the seat being engageable with the pegs, and a back frame of substantially rectangular configuration and formed of tubular metal and terminating in elongated depending pegs for detachable engagement with the sockets on the rear upright portions of the main side frames.
