June 21, 1938; w. R. MCGOWEN CHAIR Filed June 25, 1957 INVENT Patented June 21,1938

PATENT OFFICE CHAIR William R. McGowen, Pittsburgh, Pa., assignor to, The-McKay Company, Pittsburgh, Pa., a corporation of Pennsylvania.

Application June 26, 1937, Serial No. 150,457 6 Claims. (01.155-178) My invention relates to chairs or similar seating structures, and has for its object the provision of a structure of such form that the seat and back cushions or the like can readily be assembled in the chair frame, with a minimum amount of labor and with the use of a minimum number of attaching or holding elements, and wherein the cushion elements or the like can readily be removed for repairs and replacement.

Some of the forms which my invention may take are shown in the accompanying drawing wherein Figure 1 is a perspective view of the chair structure embodying one form of my invention; Fig. 2 is a fragmentary back view there- 15 of; Fig. 3 is a view on on enlarged scale taken on the line III-III of Fig. 1; Fig. 4 is a view showing a modification of the structure of Fig. 3, and Fig. 5 shows still another modification.

Referringfirst to Figs. 1 to 3,1, show a tubular metal member bent to form base bar portions 6, legs 1, and arm rests 8. The rear ends of the arm rest portions are flattened at 9 for attachment by screws to a back rest 10.

A metal channel of elongated loop form is bent 25 to form seat bars II and back bars I2, the seat bars having a cross-connecting portion 13 and the backbar elements a cross-connecting portion I4. The seat bar portions H are secured in any suitable manner to the leg portions 1, as by 30 welding, riveting, or by bolts. The flattened ends 9 of the arm rests may be welded to the back bar portions l2, if desired.

My invention is more particularly concerned with the form of connection between the back rest I!) and the seat board or cushion l5. These two members are of practically identical construction, and the description of the back cushion 1.0 will apply also to the seating element l5. The members and I5 may be upholstered or not, as may be desired. In any event, they are each provided on three sides with ledge-like projections that serve as flanges or beads that fit into the channel above described. Thus, the back rest It! has its uppermost flange fitting within 45 the portion M of the channel and its side flanges fitting within the portions l2 of the channel.

Similarly, the front edge of the seat element 15 flts within the cross bar portion l3, and its side edges fit within seat bar portions I I of the chan- 5 nel. i

The back rest is hereshown as upholstered,

and provided with an inner frame I! which is formed of wood, and of, rectangular form to stifien and maintain the cushion in proper shape and contour at its edges. The frame I! is not an essential'part of the present invention. A boardiB forms part of the cushion structure, and may be of suitable material, such as a single board, but is here shown as a laminated board. As above indicated, the board l9 will project at its upper and side edges, as indicated at 20, to flt within the channel member. A covering strip I8 of cloth-like material partially embraces the board I9 and is tacked thereto.

The channel bar above referred to is'made of spring-like material so that the side bar portions thereof can be sprung apart to permit insertion of the flanges of the back elements into the channel. In placing the backelement H) in place, it is first set low in the frame and after the bar portions I I and I2 have been permitted to spring back into place and cause engagement with the .fianges 2|], the member lll is slid upwardly to the position shown in Fig. 1, and there detachably held in place as by screws 2|.

Similarly, the seat element I5 will be inserted at a point rearwardly in the channel frame memher and slid forwardly until its front flange seats within the portion l3 of the channel. While the covering 18 is tacked to the board 19, the channel portions l2 and I4 closely embrace the edges of the cover and assist in holding it securely in place as well as serving as a finish strip for such edges.

Referring now to Fig. 4, I show a structure which can be used with the metal frame elements of Fig. 1, but wherein the seat and back cushions are of somewhat different form. In this structure a cushion board 22 has nailed thereto along each of three of its edges a bar 23 that extends outwardly from the edges of the cushion proper to form projectingflanges that fit'into the channel bar, as in the case of the flange portion 20 of Fig. 3. The upholstery covering 24 in addition to being tacked to the board 22, is clamped between the members 22 and 23. Covering material 25 is secured to the members 23 to give a finished appearance to the rear side of the cushion.

As shown in Fig. 5, the cushion element is provided with a base board 26 which corresponds to the boards l9 and 22 of the other figures, but in this case a marginal flange is provided at three edges of the board 26 by strips 21 which are nailed to the board 26 and which fit within the flange bar as in the other figures.

' I claim as my invention:

1. Chair structure comprising a base portion and seat and back members carried thereby, the said members including a channel frame member of elongated loop form the sides whereof are bent intermediate their ends to form seat and back bar portions, and being laterally yieldable, and seat and back cushions or the like having their side edges insertible into the channels of the seat and back bar portions when such portions are prung apart.

2. Chair structure comprising a base portion and seat and back members carried thereby, the said members including a channel frame member of elongated loop form the sides whereof are bent intermediate their ends to form seat and back bar portions, and being laterally yieldable, and seat and back cushions or the like having their side edges insertible into the channels of the seat and back bar portions, at points adjacent to the bends, when such portions are sprung apart, each cushion being slidable in the channels toward the end of the loop adjacent thereto.

3. Chair structure comprising a base portion and seat and back members carried thereby, the said members including a channel frame member of elongated loop form the sides whereof are bent intermediate their ends to form seat and back bar portions, and being laterally yieldable, seat of elongated loop form the sides whereof are bent intermediate their ends to form seat and back bar portions, and being laterally yieldable, seat and back cushions or the like having their side edges insertible into the channels of the seat and back bar portions when such portions are sprung apart, and arm rest members extending upwardly and rearwardly from the forward part of the base and having their rear ends secured to the back cushion and to the back bars.

5. Chair structure comprising a base portion and seat and back members carried thereby, the said members including a channel frame member of elongated loop form the sides whereof are bent intermediate their ends to form seat and back bar portions, and being laterally yieldable, and a cushion or the like having its side edges insertible into the channels at points adjacent to the bends, when the members are sprung apart, and being slidable therein to permit an end edge thereof to enter the channel, at one end of the loop.

6. Chair structure comprising a base portion and seat and back members carried thereby, the said members including a frame member of elongated loop form the sides whereof are bent intermediate their ends to form seat and back bar portions and being laterally yieldable, a cushion or the like insertible between said sides when they are sprung apart, and means for positively holding the cushion against displacement from between the bars when the bars have been released to engage the cushion.
