Application May 17, 1933, Serial No. 871,436 Renewed August 1, 1935 8 Claims. (01. 155-5.)

The main object of this invention is to provide a graceful, sturdy, and comfortable chair, economical in construction and conforming to modern methods and standards of manufacture, maintenance and utility.

A further object of this invention is to provide a chair which may be rapidly disassembled and as rapidly assembled to function as a permanent article of furniture.

A further object of this invention is to provide a chair whose frame including arms and supports are made of metal forms having both the rigidity and the degree of resilience requisite for full comfort.

A further object is to provide a chair with a rigidly held, but quickly adjustable, back.

A further object of this invention is to provide a chair having an open and accessible construction without detracting from appearance and comfort, to facilitate cleaning and repair.

A further object is to provide in such a chair a construction which will permit rapid removal and replacement of the seat to facilitate cleaning, renovation, and the like.

Other and further objects and advantages of our invention will become apparent from the description, hereinafter, in connection with the drawing, of a preferred embodiment of our invention:

In the drawing: I

Fig. 1 is a plan view of a chair embodying our invention,

Fig. 2 is a front elevation, and

Fig. 3 is a side elevation of the chair shown in Fig. 1,

Fig. 4 is a detail of the adjustment of the back of the chair i r Fig. 5 is a detail of the assembly of the frame and seat.

Fig. 6 is a detail, similar to Fig. 5, of a. modified assembly of a chair having flat frame elements in place of the round ones shown in Figs. 1 to 5,

Fig. 7 is a side view of the detail shown in Fig. 6.

The supporting base and legs are formed, out of a length of steel or metal of similar characteristics which may be easily obtained as a tube, rod or flat strip, to provide a'pair of supports l, l' at either side of the chair adapted to rest on the floor. At' the front the length of material is curved upwardly from I, as at 2, to provide the legs of the chair, and the legs 2 terminate in arms 3 extending backwardly parallel to the base elements I, l for a convenient distance. At the rear the members I are connected to each other by the bar 4, the intermediate portion of the length of tubing out of which the entire supporting structure is formed so that the portions I, 4, and I together form a roughly quadrangular base resting on the floor. It is obvious that the bar 5 4 may be omitted and the members I, 2, 3 at each side of the chair v formed separately; but the presence of the bar 4 subserves the useful function of acting to prevent separation or spreading of the rest of the supporting structure. 10

The arms of the chair are constituted by tubes or rods of steel or similar material bent into U- shape and set in a vertical plane, namely, the plane of the corresponding side I, 2, 3 of the support. The lower leg 6 of the U (which may be designated generically as 5) extends parallel to, above and in juxtaposition to the upper backward extending arm 3 of the supporting structure, and may be held thereto by pins or bolts 'l passing through both 3and 6. The ends 3 and 8 are engaged and clamped in a sleeve 8, split as at 9, and having the edges of the sleeve produced horizonta.lly inward as at It) and H to form a doubled ledge or flange. The seat l2 of the chair is provided preferably with recesses l3 on its undersurface at either side of sufllcient size to accommodate the ledge formed by flanges Ill and II; so that the seat l2 may be readily fitted to rest upon and be supported upon the said ledges. Bolts l4 passing through flanges l0 and II and entering the seat I! serve to tighten the sleeve 8 by drawing the flanges l0 and II together; and to hold the seat l2 securely to and on the ledges formed by the flanges I0 and II. It is to be noted that the sleeve 8 is suflicient to hold the ends 3 and 6 securely together; but the pins 1 are provided partly as an aid to assembly and partly to eliminate the possibility of relative ro tation of the ends.

In Fig. .6 and Fig. 7 we have shown a modi- 40 flcation adapted to use with a support formed from a flat strip of metal. The ends 3' and 5', corresponding to 3 and 6 of Fig. 5, have their flat faces in contact. Straps running from side to side of the chair support the seat; and the ends 3' and 6' are secured to the ends 25 of the strap'by bolts 30. It is to be noted that the strap ends 25 are themselves supported and rest upon the end 6'. The strap is bent down from the end 25 to form a vertical portion 26 5 adjacent to the seat l2 and then continued horizontally as at 28 to the other side of the chair, so that the straps, of which I have shown two as suflicient, though more may be used as found desirable, form a cradle or frame to receive and frictionally hold the seat l2. Bolts ll may pass through the straps and enter the bottom or the seat l2 as additional securing means, if desired. A guard or housing 2!, split at its inner side for an obvious reason, may be slipped over the ends I and O.

The back of the seat is formed of a padded or upholstered member I! having a substantially circular cross-section and provided with forwardly extending arms l6, l6, adapted to receive in channels or recesses l'l the backwardly ex-..

tending arms iii of the U 5. The arms l6 and I8 are secured to each other by means of the pawl l9, pivoted as at 20 in a recess on the under side of the arm 18, and having a nose 2| engaged in one or other of a longitudinal series of holes or notches 22 in arm ll. A spring 23 mounted in arm l6 and operating against the thumb end 24 of pawl I9 urges the nose 2| of the latter into engagement with the hole 22.

The arms l6 and I8 co-operate to form an arm rest which may be upholstered or otherwise treated or finished for a variety of purposes. The back may be a i usted by'releasing the pawl l9 and sliding the former backwards or forwards along the arms IS.

The seat l2 forms a substantially independent unit and may be quickly removed, and as quickly replaced, upon the removal or insertion of the bolts l4, The whole chair may then be rapidly disassembled by withdrawing the back l5 from engagement with the arms l8, slipping oil? the sleeve 8 and removing the pins I. Reassemlbly involves the same simple operations in reverse order.

The preferred material for the base and arms is steel tubing of a dimension suflicient to support the weight of the occupant of the chair with only a perceptible amount of resilience. This slight give of the chair is necessary for full comfort. Where a higher degree of resilience is desired we prefer to use the flat, spring shape shown in Figs. 6 and '7.

The structural independence of the backand seat, and of the several elements of the chair, permit their removal for repair, renovation, reupholstering and the like. The open framework renders every part easily accessible for cleaning and repair; and the construction necessitates only elements that are fully and completely functional thus preserving in combination with simplicity of the structure the highly aesthetic effect so desirable in articles of furniture.
