(Cl. 155-119) This invention relates to an armchair comprising a supporting structure, preferably made of steel tubes, and a piece of cloth suspended in said structure so as to bulge downwards and form a seat and back surface.

The object of the invention is to make possible the manufacture of armchairs of said type at an especial low price and simultaneously render chairs of said type more comfortable by providing the supporting structure with an annular top frame supporting a round piece of cloth along its boundary or circumference and preferably having a substantially straight lower section constituting the front edge of the chair, and by stiffening the piece of cloth in one portion adjacent to the lower section of the top frame by means of a relatively rigid disc-like member or other suitable stiffening means, thereby producing a flat seat which imparts a more comfortable shape to the piece of cloth in as much as not only the seat surface will support a person in a more comfortable way but also more comfortable supporting surfaces for the back and the sides are formed.

Another object of this invention is to provide a con struction in whichthe entire circumferential edge of the cloth, constituting the back, seat and sides of the chair, is attached to and supported by a rigid border so that the weight and stress applied to the cloth is distributed comparatively evenly to the supporting border. By this arrangement it is permissible to provide a border constructed of lighter weight and possibly cheaper material such as wood. Additionally, due to the dispersal of the stresses in the fabric, resulting from this construction, there is less possibility of the fabric being overstressed and damaged.

Further objects and features of the invention will appear from the following description when read in conjunction with the accompanying drawing in which an embodiment of an armchair according to the invention is illustrated by way of example, and in which:

Fig. 1 is an elevation of the chair, in part in a vertical cross-section;

Fig. 2 is a corresponding plan of the supporting structure;

Fig. 3 and Fig. 4 are central vertical sections on a greater scale through the parts which in Fig. 1 are indicated by the circles HI and IV, respectively.

As illustrated in the drawing, more particularly in Figs. 1 and 2, the supporting structure of the chair comprises a horizontal annular bottom frame 1 and an inclined annular top frame 2 together with legs 3 and 4 disposed between said two frames and interconnecting the same. Preferably, the supporting structure is made of lacquered steel tubes and it should be capable of piling.

The piece of cloth is preferably suspended within an annular border of the same shape as said top frame and fitting around said top frame, said border being removable with respect to said top frame. In the embodiment illustrated said border consists of two interconnected rings 5 and 6, one of said rings 5 being somewhat smaller than United States- Patent 0 the other 6 and supporting said piece of cloth or fabric 7, while the larger ring 6 is disposed below the smaller ring 5 and fits around the outside of the inclined top frame 2 substantially like a rim. Said rings could be made of steel tubes but preferably they consist of steamed wood or of cane. The lower section of the inclined frame is straight and alsojthe corresponding sections of the rings 5, 6 are: straight for constituting the front cdgeof the chair, as illustrated in Fig. 2. The rigid seat 8 could be mounted directly upon the continuous piece of cloth 7, as indicated in Fig. 1, but preferably the arrangement is used which is illustrated more clearly in Figs. 3- and 4.

Accordingto Figs. 3 and 4 the piece of cloth'7 is supported by the ring 5 by means of a strip of cloth 7'. which is stitched to the piece 7 through a doubled strip 9 consisting of'plastic-coated cloth or theilike and enclosing a cord 10 for forming a bead. The strip 7' is nailed to the ring 5, as indicated by 11, and extends between the two rings 5 and 5 which are screwed together by screws indicated by 12. The seam 13 extends along the upper section of the ring 5 and along both lateral sections of the same down to the edges of the seat. In the embodiment illustrated the relatively rigid seat consists of a plywood disc 14 and a stufling 15 together with a bottom covering 16 and a top covering 17, both consisting of cloth. At the front edge of the seat, the covering 17 is sewed to the strip 7' through the doubled strip 9 enclosing the cord 10. This seam is indicated by 20. At the rear edge and both lateral edges of the seat, the piece of cloth 7 is sewed to both coverings 16 and 17 through a similar doubled strip 21 enclosing a cord 22. This seam is indicated by 23. When the seams 20 and 23 have been made the stufliing 15 and the plywood disc 14 are inserted. Then, said disc 14 is fastened by nailing at the rear edge and the lateral edges of the seat, as indicated by 24. Finally, the covering 15 is nailed to the front edge of the seat, as indicated by 25. The weight loading upon the seat when in use is substantially supported by the seams 20 and 23.

Obviously, the chair according to the invention is more comfortable than the well-known tubular-steel chairs with seats of cloth. Moreover, the border formed by the two rings 5, 6 and supporting the piece of cloth together with the seat can easily be removed from the inclined top frame of the supporting structure. Thus, several chairs can be stored and transported while occupying a small space, as the supporting structures are capable of piling and the border together with the seat can be laid together to a flat form. When the chair is used in a garden or the like the border together with the piece of cloth can easily be taken into the house during night or rainy weather, while the supporting structure may be left out of doors.

If required, one or more Wing screws may be inserted in the upper section of the lower ring of the border, as indicated by 26 in Fig. 3, so that the border is held in its position on the frame. Then, when removing the border one has to raise the lower section of the border at first.

It should be understood that the invention is not restricted to the embodiments described and illustrated by way of example, many modifications being possible without departing from the principles of the invention as appearing from the subsequent claims.
