Chair with clampable seat and backrest

The innovation relates to a chair which has a support frame for a seat surface component and a backrest, the Frame preferably consists of a metal tube.

: It is known, usually the seat and the backrest on the frame with a plurality of screws through one in; to fasten manual operation. This is disadvantageous since it requires a relatively long time compared to the other operations in the manufacture of the chair.

The innovation is based on the task for the sake of a more rational Production on an industrial scale to indicate a generic chair in which the assembly of the various Components simplified and less needed to manufacture it | Time is required. |

According to the innovation, this object is achieved by a chair that ^ a support frame for a seat component and a back |, has backrest, this seat surface and the backrest with;

elastic hooking or, Anklammereinrichtungen are provided, the aas clamping the seat surface and the ¹ back to said frame enable, but such that a locking in juxtaposition in or on this frame is possible by simple fositionierung and / or Einrastdruck.

Preferred embodiments of the invention are shown in the drawing and are explained in more detail below. Show it echematically;

Figure 1 is a perspective view of the chair with a separate seat and back!

Figure 2 err a lateral section along the line I-I of The seat of the chair from FIG. 3 in particular;

FIG. 3 shows a view from below of the seat according to FIG. 2;

Figure 4 is a vertical, lateral cross section of the! Chair shown in partial view attached backrest.

From Figure 1 it follows that the innovation according to the chair from a rigid metal support frame A, a Sitzflächenbautexl B and a backrest C consists.

The frame A in this special Pail consists of 2WeI metal tubes, suitably shaped so that when assembled they form a chair.

The seat B and the backrest Ö can preferably be made of Sheet steel can be made which is painted or coated with any suitable material or with a plastic molded sheet is covered.

In the present case, the frame A contains two horizontal cross bars 1, 2, which can be designed as tubes, as flat bars or as round bars, at a certain distance from one another are arranged and lie in the seat surface level, and further from two horizontal cross bars 3, 4, C for the backrest) which are essentially an extension of the tubes that form the feet 5, 6 and 7, 8, respectively.

Figures 2, 3 and> '4 show that both the seat and the Backrest pairs which are identical and opposite to one another, i.e. bear angular profile parts 9 which have a snap-in seat 10 for the corresponding pairs of cross bars 1, 2 and 3, ^ form, and e.g. punched out of iron or sheet steel or the like. have been.

In the present case, the pairs of profile parts 9 are electrical, welded point by point to the surfaces of the seat or the backrest B and C, but it belongs to the spatial form of the innovation, that both the seat surface B and the surface of the back

-H-

lshne C can be made from sheet steel that is so shaped and is cut that the angle profiles 9 can be obtained by cutting or punching from the seat itself, the is provided (disguised) with these.

Another embodiment provides that these angle profiles can be attached to a molded plastic film or made from it .

In individual cases, the frame of the chair A, according to - ■ ig. 1 of two or the like that can be screwed together. Components be assembled, wherein the first component consists of the pipe components 5, 3, 6 with the cross bars 1,2 and the second component consists of the pipes 7, 4, 8; in that case it would turn out to be a fastening system for screwing the two frames together by attaching screws along the dash-dotted lines, which are denoted in the figure with the reference character ζ.

With this spatial shape, a chair is created that can be completely dismantled, easily assembled and shipped the storage has an extremely small footprint.

Details of the execution can be modified without affecting the general design, thanks to the innovation; Here it always comes down to the individual modification .
