United States Patent Ofiice 3,929,163 IPatented Apr. 10, 1962 3,029,108 CHAIRS Wayne W. Good, Sturgis, Mich, assignor to Harter Corporation, Sturgis, Mich, a corporation of Michigan Filed Mar. 21, 1958, Ser. No. 723,028 6 Claims. (Cl. 297-420) This invention relates to chairs of the non-adjustable type. The main objects of this invention are,

First, to provide a chair which may be formed of relatively light stock and still be very strong and rigid.

Second, to provide a chair structure having these advantages invwhich seat and back and arm supporting parts are assembled as a unitary structure, permitting relatively wide variation in the details of the seat and back and particularly the upholstering thereof.

Third, to provide a chair structure having these advantages which may be produced very economically.

Objects relating to details and economies of the invention will appear from the description to follow. The invention is defined and pointed out in the claims.

A preferred embodiment of the invention is illustrated in the accompanying drawing, in which:

FIG. 1 is a side elevational view of a chair embodying my invention.

FIG. 2 is a fragmentary vertical section.

FIG. 3 is a fragmentary perspective view of the assembled frame unit.

FIG. 4 is an enlarged fragmentary view in section on a line corresponding to line 4-4 of FIG. 3.

FIG. 5 is an enlarged fragmentary view partially in section on a line corresponding to line 5-5 of FIG. 2.

FIG. 6 is a view through the arm and the supporting side bar therefor on a line corresponding to line 6-6 of FIG. 2, upholstery being omitted.

The embodiment of my invention illustrated is primarily designed as an oiiice chair, although adapted for various uses. The chair of my invention includes a frame assembly illustrated in FIG. 3 which view also includes a seat bottom plate. The laterally spaced pairs of front and rear legs 1 and 2 are disposed in upwardly converging relation. Their upper ends are connected by the flat side bars 3 which are disposed on the upper ends of the legs and fixedly secured thereto desirably by the welds 4. The rear legs are preferably inclined at a substantially greater angle to the side members than the front legs which are disposed at approximately a right angle thereto so that the lower ends of the rear legs are positioned a substantial distance rearwardly of the seat and back, which arrangement results in stability, that is, the chair is not easily tilted rearwardly.

The legs are connected by the cross pieces 5 which are disposed on the inner sides thereof and desirably secured thereto by welding, the welds not being indicated: In production the welds are made as inconspicuous as it is practical and'at the same time secure a strong connection for the parts. The cross bars 5 are connected by the tie bars 6 which are disposed so that their upper surfaces are substantially flush with the tops of the cross bars and are fixedly secured to the cross bars as by welds indicated at 2-. a

The side bars 3 are provided with longitudinally spaced holes 8 while the tie bars 6 are provided with longitudinally spaced holes 9, these holes being adapted to receive fasteners for the arm members and the seat respectively.

The seat, designated generally by the numeral 10, is provided with a bottom plate 11 which is secured to the tie bars 6 by bolts 12. The manner of attaching the upholstery to this bottom plate is not illustrated but it will be understood that it is desirably mounted thereon so as to form an assembled unit therewith, although it may be in the form of a cushion superimposed upon the bottom plate 11. However, for office and like use, it is desirable that the upholstery be fixedly connected to the supporting or bottom plate 11.

The arm members 13 are desirably formed of wood and are superimposed upon the side bars 3, being preferably recessed at 14 to receive the same, see FIG. 6. These arm members are secured to the side bars by means of bolts 15 disposed through the holes 8 in the side bars, the upper edges of the arm members having vertical recesses 16 therein adapted to receive the cup-shaped nuts 1'7, see FIG. 3.

The back, designated generally by the numeral 18, comprises side uprights 19 connected by the top, bottom, and intermediate cross pieces Zll, 21 and 22 respectively, see FIG. 2. The back is provided with upholstery 23 which includes a rear panel 24 disposed on the rear side of the frame and detachably secured thereto as by the screws indicated at 25, see FIG. 5. The back is supportedly mounted on the arms by means of the vertically spaced pairs of bolts 26 which are desirably threaded from end to end and have flattened or disk-like heads 27 threaded upon their outer ends and seated in the recesses or countersinks 28 provided therefor, see FIG. 5. These back supporting bolts are clamped upon the arms by means of the nuts 29 threaded upon the bolts in clamping engagement with the washers 30. The arm uprights are disposed on the bolts, Washers 31 being disposed between the nuts 29 and the back uprights. The bolts are arranged through the supporting plates 32 disposed on the inner sides of the arm uprights and secured thereto by screws 33. Bolts project through these reinforcing plates and are secured by the nuts 34. This provides a strong and rigid connection for the back to the arms and at the same time one which is inconspicuous.

The arm member coverings 35 in the embodiment illustrated are conformed to the arm members, but it will be understood that suitable padding or cushioning may be provided if desired. The rear portion 24 of the back is desirably made detachable so that it can be positioned after the back has been mounted and it efifectively conceals the back attaching means. a

The legs and the cross bars are desirably formed of tubular stock which contributes to lightness and at the same time the legs may be shaped to secure a graceful appearance as is illustrated in FIG. 1. The legs are desirably provided with foot pieces 36 of the tiltable anti-slip type. The assembling of the legs, side bars, cross bars and tie bars as an integral unit results not only in a rigid structure of comparatively light stock, but as stated it permits a wide variation in the matter of upholstery. The seat bottom plate when secured to the tie members also serves as a bracing or strut element to assist racking stresses on the several parts at their points of connection, and this further contributes to the end that these frame parts may be made of relatively light stock.

I have illustrated and described my invention in a highly practical embodiment thereof. I have not attempted to illustrate or describe the various adaptations particularly from the upholstery angle, as it is believed that this disclosure will enable those skilled in the art to embody or adapt my invention as may be desired.

Having thus described the invention, what is claimed as new and desired to secure by Letters Patentis:
