8 Claims.

This invention relates to metal chair construction and more particularly to metal chairs 'involving stamped metal chair backs and seatsand bent or formed stock frames therefor.

Prior to the instant invention it has been customary to stamp ,metal'chair backs and seats out of sheet metal as individual units; form rods, metal stripsor tubes into chair frames; drill the chair backs, and seats, and frames at a plurality of locations to take nuts and'bolts, and then ship the chairs in knockdown form to retail stores where the .chairs were assembled by the use of bolts to lock the frames, and chair backs, and seats together. While this construction permitted chair parts to be shipped economically,

the assembling of the parts into the finished chair was .notan easy job, and required considerable time and care to prevent scratching of the finish and otherwise marring the new appearance in order to prevent the chairs from becoming unsaleable.

In those prior metal chairs in which the-chair frames acted as the chair arms, it was conventional to form the stock that madeup the chair arms in a manner to copy the formation of the conventional stuffed or wooden chair. Thus formed metal arms were not always comfortable as arm rests for their upper surface areas did not correspond to the upper surface areas of the wooden and stuffed chair from which they were copied. 7

It is an object of the instant invention to provide a metal chair comprising stamped back and seat parts and form metal stock frames which may be readily assembled with a minimum of bolted joints.

It is a furtherobject of theinstant invention to provide ,a metal chair including a formed metal stock frame with-a portion ofthe frame including novel arm .rests which insure a restful position of users arms, though the bearing surface of the metalstock be relatively small.

Other objects and the nature and advantages of the invention :will be apparent from the following description taken in conjunction with the accompanying drawings, wherein:

Fig. 1 is .a view in perspective of a chair inaccordance with the invention;

Fig. 2 is a section takenalong line 2 -2 of Fig. l and looking-in thedirectionof.thearrows;

Fig. 3 is a section taken along line 33 of Fig. 1 and looking inthe direction of the arrows;

Fig. 4 is a transversesectional view of the chair shown in Fig. 1; v

Fig. 5 is a perspective fragmentary view-bra rear portion of the seat of the chair shown in Fig. 1;

Fig. 6 is a fragmentary perspective view of a portion of the, chair back adapted to cooperate with the fragment of the chair seat shown in Fig. 5; and,

Fig. 'l is a fragmentary sectional View of the joint between the chair backand chair seat prior to complete-assembly.

Referring to the drawings, the chair I0 com-' prises a stamped metal back II, a stamped seat l2 and a one piece tubular frame I3, which frame includes side arms l4 and floor bearing support vI5. Though the frame I3 is illustrated as being of one piece and made of tube stock, it is contemplated that this frame may be made of flat bar stock, of tubular stock in more than one piece, and of stock of other sectional configuration. When the frame I3 is made of tubular stock and of more than one piece, it is preferred that the rear portion of the bearing support l5 take that form of a removable U member which is adapted to be telescopically associated with the rearwardly extending side bars l6 of the bearing support l5, and when this embodiment of the invention is utilized the removable U shaped piece is bolted to theflrearwardly extending side arms 16 of the floor bearing support l5.

Referring ,in particular to Figs. 1, 2 and 3, the chairback is a one piece metal stamping comprising a generally concave front portion I1, rearwardly turned side portions l8 and inwardly turned .ends l9. This construction has been found to have inherent great strength and contributes to the comfort of the user of the chair l0. Further strengthening the chair back II are the embossed portions 20 which also serve as a metal take-up expedient for upon the stamping of the metal chair back to form the rearwardly turned portions [8 and the inwardly turned portions L9 excess metal is present in the concave front portion I"! which would buckle upon use if it were not for the take-up embossings 20. Hence, the metal take-up embossings 20 serve a dual function of strengthening the chair back by increasing the radius of gyration of the front I! of the chair back and also they take up excess metal to prevent buckling. At the lower central portion of the chair back II a relatively large embossing 20a not only makes for the two advantages set forth above but also makes for the comfort of the user by providing an enlarged depressed lower portion 20b which accommodates the rear portions of the hips of the user, thereby making the chair backapproach the comfort of a stuffed chair though the chair back is made of metal.

Referring to Figs. 1, 4, and 5, the chair seat I2 at its rear edge 2| is formed with a pair of rearwardly extending corner portions 22 which serve to lock the chair back II against movement to either side after the chair back and chair seat are assembled in operative position. The chair seat I2, like the chair back, has a downwardly depending side portion 23 and an inwardly turned edge 24 to provide for the greater strength of the chair seat.

Referring to Figs. 4, 5, 6 and '7 the rear edge portion 2I of the seat I2 has a curled lower lip portion 25 which cooperates with the slightly larger curled lip portion 26 formed at the end of the lower portion 21 of the chair back II. The curled portion 25 connects with the rear edge 2I of the chair seat I2 smoothly, whereas the curled portion 26 depending from the lower portion of the chair back II coacts or connects with the lower portion, of the chair back in a slightly different way. The lower portion 21 of the chair back extends downwardly and outwardly to engage the rear portion 2| of the seat I I smoothly and the curled portion 26 curves in the opposite direction from the lower portion 21 to form a humped junction, whereby a smooth concealed joint between the chair back and chair seat is provided. In addition, the joint between the chair back and the chair seat need not involve any bolts or screws to hold the same in place when the frame I4 is associated with the chair back and chair seat by the bolts 28 securing the frame I4 to the chair seat and bolts 29 which secure the frame to the chair back. Referring to Fig. '7 in particular, the chair back II and chair seat I2 are shown in partially assembled position. When assembling the chair back with the chair seat the curled edge 26 integral with the chair back is hooked over the outermost edge 30 of the curled portion 25 of the chair back I2 and then the chair back II is rotated in a counterclockwise direction to bring the chair back into the position illustrated in Fig. 4 with the humped portion 3| of the chair back engaging the rear edge 2I of the chair seat I2 which rear edge portion 2I is exposed to the view of the user of the chair. The joint between the curled portions 25 and 26 does not extend into the rearwardly extending corner portions 22 of the chair seat I2 as will be readily apparent upon inspection of Figs. and 6 which show the elements ready for assembly.

Referring to Figs. 1 and 4, it will be apparent that the upper side portions 32 of the chair frame I4 are angularly disposed in an unconventional manner with the rear portions elevated and the front portions extending toward the seat I2" of the chair. This special configuration permits of a particularly desirable reposed position for the arms while they were bent with the hands upon the lap of the user of the chair and the elbows extending across the chair arms and with the hands lower than the elbows as is most comfortable. It will be appreciated that as the chair frames are made of metal stock which may be quite narrow, they are not as comfortable as upholstered arms when the arms of the chair are used for the purpose of resting the forearms of the user. When the forearms of the user are rested not directly above the arms of the chair and accordingly if the arms of the user are crooked with the elbows extending across the sloped portions 32 of the frame I4 with the hands lower than the elbows a very comfortable rest position will be achieved. The upper rear portions 33 of the frame I4 depend downwardly and are engaged at an intermediate point with the rearwardly depending portion I8 of the chair back II. This engagement is made by means of bolts 29. The bolts 28 and 29 are the only bolts used to hold the chair in assembled position; the only other fastening means is the joint between the curled ends 25 and 26 which requires no bolts and is locked in position by the rearwardly extending corner portions 22 of the chair seat I2. As the outside diameter of the curled portion 25 is greater than the opening between the end 34 and the hump 3| of the chair back II, the assembling must take place as illustrated and described in connection with Fig. 7.

As the metal chairs described above are made of simple elements, they are relatively inexpensive to fabricate. Decoration may be made by simply dipping the parts in desired color pigmented paints or by spraying or otherwise inexpensively coating the parts. It is contemplated that the parts be shipped unassembled, in order that freight rates be a minimum for in unassembled position the chair parts take up much less volume than when the chair is assembled. While the chair frame has been shown in one piece is it contemplated that this be made in a plurality of parts so that it may be packed in a smaller volume. These features make it possible for the retailer to offer to the consumer at a relatively very low price, a chair which is comfortable, attractive, fool-proof, and otherwise desirable for commercial, outdoor, indoor play room or other use. Upon receipt of the parts by the retailer it is only necessary to first assemble the chair back II and chair seat I2 by hooking the two curled ends together as shown in Fig. 7 and then rotating the chair back II in a counterclockwise direction to that shown in Fig. 4, then the chair frame I4 is bolted to the chair back and chair seat by the bolts 29 and 28 to form a relatively strong assembly with a minimum of joints and bolts.

It will be obvious to those skilled in the art that various changes may be made in this device without departing from the spirit of the invention and therefore the invention is not limited to what is shown in the drawings and described in the specification but only as indicated in the appended claims.
