CHAIR Filed March 5, 1962 INVENTOR. (/OVATHAN 1 GIN/77' United States Patent 3,142,514 CHAIR Jonathan J. Ginat, 449 Antoinette, Detroit 2, Mich. Filed Mar. 5, 1962, Ser. No. 177,600 8 Claims. (Cl. 297449) The present invention relates to an improved chair.

An important object of the invention is to provide a chair of a novel structure which presents an appearance of lightness and airiness and which tends to create an impression or illusion as if it floats in air.

A further object of the invention is to provide a chair of an improved and simplified construction having a relatively few different basic parts which can be easily manufactured and assembled on a mass production basis.

A still further object of the invention is to provide a chair of an improved construction which permits the chair to be easily assembled and disassembled and which permits its parts to be nested or stacked for shipping and storage purposes.

According to a broad aspect of my invention, the novel chair is characterized by a frame structure, a seat, and means for supporting the seat in cantilever fashion from the frame structure. More particularly, the frame structure includes a U-shaped member to provide a base of relatively large horizontal dimension or area for resting stably on a floor or other surface, the U-shaped member being also of relatively small vertical dimension to minimize its prominence and conspicuousness. The U-opening faces the front of the chair and the middle interconnecting leg of the member is disposed to the rear of the chair, this arrangement further minimizing the conspicuousness and prominence of the base when viewed from the front of the chair. To this middle interconnecting leg at the rear of the U-shaped member is attached an upright or substantially vertical member which carries the chair seat. The seat is supported in cantilever fashion from this upright member. This combination of base, upright and cantilever seat creates a remarkable appearance, particularly when viewed from the front end, of lightness and airiness and a virtual illusion as if the seat floats in air.

According to a further feature of my invention, the chair includes a first U-shaped member horizontally disposed to rest stably on the floor or other surface, at least one upright member attached to the U-shaped member, a second U-shaped member attached to the upright member and supported thereby above the first U-shaped member, and a seat carried by the second U-shaped mem-. ber. The two U-shaped members are of the same material and configuration except the second is preferably of shorter dimension. This arrangement reduces the number of different basic parts to be manufactured. A chair back is also carried by the second U-shaped member, which is of the same material .and shape as the seat, thus further minimizing the number of different basic parts. In addition, the upright support preferably consists of a pair of parallel, spaced vertical members, both of the same material and shape, thus further minimizing the number of different basic parts. In all, but three different parts need be manufactured, each part being in duplicate in each chair, that is, two U-shaped members, two vertical members, and two similarly curved members, one serving as the seat and the other as the back. In connection with the latter two members, the seat and the back are made of the same material and curved to the same shape, but they are preferably trimmed to slightly different dimensions, as in the case of the two U-shaped members.

According to a further feature of my invention, the seat and back of the chair are supported for quick and easy assembly and disassembly which permits these parts and ice the frame structure to be nested or stacked for shipping and storage purposes.

The novel features that are considered characteristic of my invention are set forth with particularly in the appended claims. The invention itself, both as to its organization and method of operation, as well as additional objects and advantages thereof, will best be understood from the following description when read in connection with the accompanying drawings, in which:

FIGURE 1, by way of illustrating a preferred embodiment of my invention, is a front perspective view of a chair constructed in accordance with the invention;

FIGURE 2 is a rear perspective view of the chair of FIGURE 1; and

FIGURE 3 is an enlarged fragmentary view illustrating the manner in which the seat and back are supported from the frame structure for quick and easy assembly and disassembly.

As shown in the drawings, the novel chair comprises a frame structure consisting of a first U-shaped member, generally designated 10, a pair of upright members 20, 22, and a second U-shaped member, generally designated 30. A chair seat 411 and a chair back 51), both supported by the second U-shaped member 31 complete the basic parts of the chair.

U-shaped member 10 serves as the base of the chair and provides a relatively large horizontal supporting surface for resting stably on the floor or other surface. The vertical height of this member, however, is relatively small to minimize its prominence or conspicuousness, particularly where the chair rests on a carpeted floor. Member 10 consists of a pair of parallel end legs 12, 14 and a middle interconnecting leg 16, arranged such that leg 16 is disposed to the rear of the chair and the U-opening, that is the space between legs 12, 14, faces the front of the chair. Base 10 is preferably formed of metal stock of about inch thick and of about 2. inches wide across middle leg 16, the juncture of legs 12, 14 with the middle leg also being of about 2 inches wide and tapering to 1 inch at their ends.

Upright members 20 and 22 are also of metal and are attached, as by welding, to the mid portion of interconnecting leg 16. They serve as the sole support for the second Ushaped member 30, the chair seat 40, and the chair back 50. Members 20 and 22 are made of slim but sturdy construction as it is desirably that they too be as inconspicuous as possible in the finished chair, consistent with their supporting function.

The second U-shaped member 30 is carried at the top of the upright members 20, 22, where it is attached as by welding. Member 30 is formed of the same material and shape as base 10, namely with a pair of end arms 32, 34 and a middle interconnecting arm 36, except that the end arms 32, 34 are somewhat shorter than legs 12, 14 of base 10. Member 30 extends above base 10 but is at a small angle relative to the horizontal. It is thus seen that member 30 is supported in cantilever fashion from uprights 20, 22.

I have found that welded joints between members 10, 20, 22 and 30 are adequate to provide a strong, sturdy frame structure for the chair, but it may be desirable in some applications to provide additional reinforcement at these joints.

Chair seat 40 and also chair back 50, are carried by arms 32 and 34 of th upper U-shaped member 31) such that it may be easily assembled and disassembled. As shown particularly in FIGURE 3 illustrating an enlarged portion of the fastening arrangement, each of these arms carries four pins 60, two secured to the top surface of the arm and extending upwardly and two secured to the lower surface of the arm and extending downwardly. FIGURE 3 illustrates only one of each of the upper and lower pins 60 carried by arms 32. Pins 60 are secured to the arms 32 and 34 as by welding and are receivable in bores 62 extending for a small distance into the edges of chair seat 40 and chair back 50. The pins 69 are formed with an enlarged flattened head 64 which spaces seat 40 and back 50 from arms 32 and 34 a small distance, about inch. The end of each pin 60 opposite to the enlarged head 64 is formed with a radial opening 66 adapted to receive a screw 68 which also passes through a corresponding opening in the chair seat 40 and back 50.

To remove or to assemble chair seat 40 from the frame structure involves merely removing or inserting the two lower screws 68 cooperating with lower pins 60 of arms 32 and the two lower screws 68 cooperating with the lower pins 60 of arm 34, or a total of four screws. Similarly, to remove or to assemble chair back 50 involves merely removing or inserting the four upper screws 68 cooperating with the upper pins 60 of arms 32 and 34.

Chair seat 40 is formed of pressed plywood, curved to provide a pair of upstanding ends 42, .4 bordering the seat portion 46, and a central cutout 48 to the rear of the seat portion 46. The chair back 50 is similarly formed of pressed plywood curved to the same configuration as seat 40, namely with a pair of ends 52, 54 curved from the back portion 56 with the same curvature as ends 42, 44 with respect to seat portion 46. Utilizing the same material and configuration for these two parts reduces the basic types of parts necessary for producing a chair. Back 50, however, is trimmed slightly differently from seat 40 so that the ends 52, 54 provide smooth, clean, continuous lines with ends 42, 44 of the seat.

The cantilever support for the chair seat, in the arrangement illustrated, produces an effect of lightness and airiness, almost as if the chair floats in air, when the chair is viewed from the front. This effect is enhanced by the U-shaped base disposed so that the U-opening faces the front of the chair, and further by the small vertical distance the base extends from the floor. This arrangement places the chair seat (and back) in the foreground and the supporting frame structure in the background. The frame structure presents a neat and unbulky appearance, and yet it is sturdy enough for all normal applications.

With the two U-shaped members 10, constructed of the same material and configuration, the two vertical uprights 20, 22 constructed of the same material and configuration, and the chair seat and back also constructed of the same material and configuration, the main parts for building a chair are reduced to three types, each part being substantially in duplicate. Of course, as explained above, the dimensions of these parts may vary, as was true in the case of arms 32, 34 of member 30 being shorter than legs 12, 14 of member 10, and back 50 being trimmed a little differently from seat 40. But the trimming expense to adjust for these dimensional variations is small compared to the manufacturing expense for making these parts, had they been of different material or configuration. In all, this chair lends itself nicely to being manufactured and assembled on a mass production basis.

Further, the ease in which the chair seat 40 and back 50 may be removed and inserted from the frame structure enables these parts to be conveniently stacked or nested for shipping or storage, which is a further highly advantageous feature in chair constructions.

While there has been described a chair constructed in accordance with a preferred embodiment of my invention, it will be understood this embodiment is illustrative only, and that many applications, variations or modifications of features of the invention as set forth in the following claims will be readily apparent to those skilled in the art.
