DE1059059B - Radio receiver housing - Google Patents

Description

The invention relates to a housing for radio receivers, television receivers, music devices or the like. And method for its preparation. The previously known device housings are mostly from one composed of a larger number of wooden parts. It is also known to consist of a single receiver housing to manufacture hood-like molded plastic part. Here the openings in the housing walls produced simultaneously with the pressing process. The latter housings are cheap to manufacture, however they are only used for smaller devices because of their unfavorable acoustic properties.

It is already known to press molded parts from wood fibers and a synthetic resin binder which serve as containers for liquids, food or the like, and to use appropriate sheet material in furniture production. , ₌ .. _t . .

In a known method of division, hollow table or chair feet are compressible chip or fiber masses against the back of a Pressed mold made of inlaid veneer. It is also known to make plywood furniture by pressing the plywood sheets on a suitable model shape corresponding to the outer surface of the furniture and to cut out the openings for drawers, doors and the like from the resulting plywood shell.

The method according to the invention for producing radio and television receiver housings consists in that the housing, from its front and rear walls and optionally from the side walls larger areas are cut out than a hood-like body made of synthetic wood that is open on one side pressed and provided with veneer in such a way that the veneers are applied after the pressing process or already inserted into the mold in a manner known per se and thus during the pressing process with the Synthetic wood mass are connected. Housing produced by the method according to the invention for Radio receivers or the like have the advantage of favorable acoustic properties with a good appearance and at the same time are suitable for cheap mass production.

Further details of the invention can be found in the following description of an exemplary embodiment.

As an embodiment of the invention, the figures show a radio receiver housing, namely shows

Fig. 1 the front view,

Fig. 2 shows the side view and

.. '. '. Synthetic wood' produced. To manufacture such a housing, the procedure is, for example, that the veneers, which form the outer surface of the housing, are placed in the mold and are connected to the synthetic wood molding compound during the pressing process. However, it is already relatively easy to provide the raw and smooth-surfaced housing coming from the press mold with a veneer, especially if the vertical ones. Edges of the case are rounded. With the last-mentioned type of veneer, the cutouts in the housing can be made before the veneer is applied. In many cases it is desirable to provide a removable rear wall, in Fig. ¹ 3 denoted by 2 to be provided. According to the invention, a surface milled out of the rear of the housing is used for this purpose. This surface 2 is expediently milled out after veneering the entire housing and later fastened again with the aid of strips 3 or the like. The slot 4 created by the milling serves, together with any holes provided in the bottom of the housing, for ventilation. In the exemplary embodiment shown, the receiver chassis 5 is fastened to a base plate 6. The base plate 6 can consist, for example, of the plate obtained on the front side during the production of the opening 7. During assembly, after the loudspeakers 8 and baffles 9 have been fastened, the hood-like housing is slipped over the chassis 5, which is in turn fastened to the plate 6, and fastened to strips 10. The plate 6 is in turn provided with feet 11. The appearance of the device can be improved by the connection lines 12 for antenna, pickup or the like. From below through corresponding cutouts in the base plate 6 in the chassis 5, so that the usually

sockets on the rear of the receiver fall away. In order to avoid veneering the edges of the housing cut-outs, it is advisable to Plastic or metal parts 13, which can be designed like a frame, to cover the edges use, as is known from pure wood or molded housing. If a removable Rear wall 2 is provided, the base plate 6 can also be firmly glued to the housing, and that Chassis 5 is inserted into housing 1 through the opening at the rear.
