- Filed July 15, 1957, Ser. No. 672,080;

13 Claims. (Cl. 155-2) This invention relates generally to furniture and more particularly, relates to the construction of a chair having novel means enabling a plurality of the chairs to be stacked one on top of the other. An ancillary object of the invention is the provision of such means in a chair construction which also enables a plurality of the chairs to be arranged in a row one alongside the other with adable of being stored in reduced volumes of space when not being used.

Another object of the invention is to provide a chair construction of the character described having means enabling a plurality of the chairs to be vertically nested gor stacked, said means comprising a pre-formed wire .member secured to the leg structure of the chair.

In connection with the object recited immediately preceding, another advantage to be realized from the inven- 1 tion is that said stacking means'may be modified slightly also .to enable the chairs 'to be arranged in a row side by side with adjacent chairs having the stacking means thereof 'releasably interlocked to prevent inadvertent separation thereof. v

,The foregoing and other objects of the invention will become apparent as the description thereof proceeds. A preferred embodiment of the invention has been described in detail in the following specification and illustrated in the accompanying drawing. It is contemplated that minor variations in the size, arrangement, construction and proportion of the several parts may occur to the skilled artisan without sacrificing any of the advantages or departing from the scope of the invention.

In the drawing:

Fig. 1 is a fragmentary perspective view of the chair construction embodying the invention.

Fig. 2 is a fragmentary side elevational vie w of f a stacked assemblage of said chairs.

Fig. 3 is a fragmentary elevational view showing the novel means for stacking a plurality of said chairs.

'Fig. 4 is a fragmentary perspective view of a pair of stacked chairs enlarged to show details of the invention. Fig. 5 is a front elevational view of a section of a row of chairs releasably interlocked.

Fig. 6 is a fragmentary front-elevational view looking between a pair of interlocked chairs to illustrate the manner in which they are interlocked.

. Referring now to the drawing, illustrated in Fig. l is 'to said side sections.

Patented Sept. 13, 1960 a chair construction embodying the invention which has been designated generally by the reference character 10. Chair 10 includes a molded body formed from suitable resinous material, such as a synthetic plastic, which may or may not be reinforced with fibres, to provide a curved backrest member shown partially at 12 and a seat member 14. The molded body of the chair is supported on substantially U-shaped leg members 18 and 20 secured to the bottom of the seat 14 by a pair of suitable brackets 22 (Figs. 2 and 5). The leg members may be mounted to the brackets by welding or by means of suitable clips. As orientated relative the chair seat 14, member 18 provides the front legs and member 20 provides the rear legs of the chair. Various modifications in the seat and backrest components, as well as the leg members of the chair are possible within the principles of the invention. For example, the seat and backrest members may be of the padded or upholstered variety and the leg members may be formed of individual elements otherwise suitably attached to the underside of the chair seats.

The leg members 18 and 20 are identical in construction. As shown, each is formed of metal tubing bent to inverted U-shaped configuration. Leg member 18 provides a pair of front uprights, or standards 23 and 24 and member 20 provides the rear uprights or standards 25 and 26. Each leg member is connected across the upper end thereof by the transverse support bar 27 which is secured to the brackets 22 transversely thereacross. Thus, the front uprights 23 and 24 are respectively arrayed in front of and aligned with the rear uprights 25 and 26. Each cross-bar 27 is of sufficient length so as to protrude at opposite ends respectively thereof beyond the side edges 28 of the chair seat 14. Consequently, the pairs of uprights 23, 25 and 24, 26 also are arranged respectively outboard of a side edge 28 of the chair seat. The lower end of each upright or standard carries a self-adjusting foot member 29 of well-known structure. As seen in side elevational view of Fig. 2, the rear uprights are canted rearwardly and the front uprights are canted forwardly to increase the stability of the chair.

The novel means provided for stacking the chairs 10 has been designated generally by the reference character 30, and as seen in the drawings, same is installed in a vertical disposition. Same comprises a pre-formed metal member, preferably of wire of suitable diameter to render the member 30 sufficiently rigid to achieve its functions. The member 30 is generally of open, rectangular configuration providing a bottom section 32, a pair of side sections 34 and 36 and a top section 38 generally parallel to the bottom section 32. The bottom section 32 is connected between the bottom ends of the side sections 34 and 36 and slightly offset from the side sections by the connecting segments 40 bent at right angles The top section 38 is connected between the upper ends of the side sections and likewise offset therefrom by the horizontally arranged connecting segments 42 extending outwardly perpendicular to said side sections and longer in length than the connecting segments 40. The segments 42 further are bent, downwardly to provide the continuation segments 43 secured to the ends of section 38 so that the top section 38 is disposed below the upper ends of the side sections. Because of the greater length of the segments 42, the top section 38 is offset outwardly from the bottom section 32.

A member 30 preferably is secured vertically arranged between each pair of front and rear uprights with the sections 32 and 38 thereof facing outwardly of the chair.

Thus, each chair has a pair of such members 30 installed thereon. Considering the front and rear uprights 24 and 26 of the chair 10, the member 30 is secured therebetween with the side section 34 affixed to the upright 24 and the side section 36 aflixed to the upright 26. Suitable welding techniques will suffice for installing the member 30 between said uprights 24 and 26 to achieve a smooth joint. It will be noted that the side sections .34 and 36 are angularly disposed one relative the other at the .same angle as the uprights 24 and 26 are canted so that the member 30 fits in complementary fashion between said uprights with each of the sections 34 and 36 juxtaposed an upright substantially the entire length of said section and the sections 32 and 38 laterally spaced outwardly from the plane of said uprights. The sections 34 and 36 are thus secured to facing surfaces of said uprights 24 and 26. It will be appreciated that as the angle at which the uprights 24 and 26 are canted varies, the angle of inclination of the side section 34 and 36 one relative the other also may be varied so as to permit such complementary installation of the member 30 be tween facing surfaces of said uprights.

The bottom section 32 of the member 30 has a pair of inverted U-shaped bends 44 therein which open downwardly or away from the upper section 38. Each of the bends 44 is located so as to align vertically with a horizontal connecting segment 42.

Referring to Figs. 3 and 4, there has been illustrated the manner of nesting or stacking a pair of chairs. For purposes of this disclosure, the uppermost chair of Fig. 4 has been designated and parts thereof corresponding to identical parts of the bottom chair 10 likewise have been primed. As seen in Fig. 3, the bend 44 of the member 30 receives therein the segment 42 of the member 30 of the bottom chair. As seen in Fig. 4, the upper chair 10' is thus supported by means of the bends 44 thereof resting upon the segments 42 of the lower member 30. The nested chairs are prevented from sliding laterally one relative the other by reason of the member 30' provided on the opposite side of each chair. Thus, the sections 32 and 38 of the member 30 on both sides of the chair 10' spaced outwardly of the plane of each pair of front and rear uprights will prevent the uppermost chair '10 from being slided off the chair 10. Of course, engagement of the sections 42 in the bends 44 also prevents lateral shifting of the chairs when stacked.

It will be appreciated that the member 30 may be installed spaced from the ends of the uprights between which secured at a predetermined desired distance so that when chairs are nested, the backrest members of the nested chairs are complementarily nested also one with the other on adjacent chairs. This is seen in Fig. 2 to advantage, the members 30 of said nested assembly of chairs being located on the chairs to permit this compact .nesting likewise to be achieved. By deposing the uprights outboard of the lateral edges 28 of the seat, the chairs may be nested with the seat member of the upper chair close adjacent or resting upon the seat of the chair immediately below.

The member 30, by reason of its advantageous construction, also can be constructed to enable the chairs to be arranged in a row one alongside the other and releasably interlocked. Such an arrangement is seen in Fig. 5, adjacent chairs being interlocked to prevent separation and lateral displacement one relative the other. This is accomplished as seen in Fig. 6, where the system of double primed characters are used to distinguish between chairs. Thus, on each chair, one of the members designated 30" on the same side of each chair is formed so that segments 43 are slightly longer than their counterparts 43 on the member 30 of the adjacent chair and slightly canted outward of the segment 42' to which connected. The segments 43 thus can be passed down- I wardly between the segments 43 of member 30 on the adjacent chair and the chairs are interlocked. In order to separate adjacent chairs, it is necessary to lift the chair having member 30 to retract said member 30" from between the segments 43. To facilitate such interlocking engagement, the segments 43" may be canted outwardly of the adjacent upright 24", as are the segments 43 relative the upright 24.

It is believed the invention has been described in sufficient detail to enable the Skilled artisan to understand and practice the same.
