No. 465,286 Claims priority, application Germany, July 2, 1964, P 34,614 1 Claim. (Cl. 3127) ABSTRACT OF THE DISCLOSURE A metal radio or television cabinet having a series of veneer sheets applied to the outside of the cabinet wherein the veneer is attached by means of a series of fasteners and an adhesive layer. The adhesive layer is also a filler which closes the cavities and gaps between adjacent veneer sheets.

This invention relates to cabinets, intended more particularly for radio or television receivers, having a metallic supporting frame which is covered with wood or synthetic resin sheet material.

It is known to manufacture cabinets for radio or television receivers from a metallic supporting framework which is subsequently covered with sheet material. While high-quality wood frame material can be saved by use of a metal frame, such cabinets are expensive because the gaps occurring between the contacting covering sheets must be filled with a filler which is time consuming and expensive because the individual covering sheets cannot be cut to size so accurately that gaps can be avoided. Furthermore it is also time-consuming and troublesome to secure the plates to the supporting frame, which is usually effected by screws.

According to the invention the above noted disadvantages of known cabinets having a metallic supporting frame covered with sheet material are avoided.

The method according to the invention affords the advantage that even with comparatively large tolerances in the dimensions of the covering sheets or between those surfaces thereof which will contact one another, no gaps remain since an adhesive is automatically squeezed betwen the contact surfaces of the sheets as the sheets are forced onto the frame in one operation.

In order that the invention may be readily carried into effect, one embodiment thereof will now be described in detail, by way of example, with reference to the accompanying diagrammatic drawing, in Which:

FIGURE 1 shows a metallic supporting frame of a cabinet for a television receiver;

FIGURE 2 shows a section of the cabinet frame with the parts prepared for compressing, and

FIGURE 3 shows the section 2 of the completed cabinet.

The supporting frame of the cabinet according to the invention comprises a metallic frame 1. Individual circuit elements inside the apparatus are provided on the metallic frame in known manner. The metallic frame 1,

"ice

which must of course be invisible from the exterior, is covered with wood veneer sheets or plates 3. To this end the sheets 3 are arranged on all sides about the metallic frame 1 in an apparatus (press) not shown. A layer 7 is applied to surfaces 5 of the supporting frame which are to be covered, in order to initiate the covering operation. The layer 7 consists, for example, of sponge material impregnated with adhesive. Further nail-shaped fastening projections 9 extend from the surface of the supporting frame 1 to be covered.

During the covering operation the sheets 3 are forced against the surfaces 5 of the supporting frame 1, the nails 9 thus penetrating into the plates 3 and establishing a mechanical coupling between the frame 1 and the sheets 3. The sponge material comprising layer 7 or at least the adhesive contained in it is squeezed out laterally as far as possible and penetrates into cavities 11 and gaps 15 which form between adjacent surfaces 13 of the sheets 3. The cavities 11 and the gaps 15 are filled completely. Furthermore the adhesive causes the covering sheets to be adhered together, as well as to the metal frame. This results in a very robust cabinet which need be covered with only comparatively thin veneer sheets.

The adhesive impregnating the porous material may be any material having a high capacity for flowing, more particularly a synthetic material, if the manufacturing tolerances between the individual plates make this necessary.

The nail-shaped fastening elements 9 are punched out of the cabinet frame 1 and hence are not detachable.

The above cited embodiment is intended as exemplary only, and while We have described our invention with a specific application and embodiment thereof, other modifications Will be apparent to those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claim.

What is claimed is:

A cabinet comprising: a metal frame member, a plurality of fastening projections integral with said frame member, and extending therefrom, a porous material substantially overlying said frame member, an adhesive impregnating said porous material, and a plurality of adjacently positioned veneer sheets substantially covering said frame, wherein said sheets are in overlying relation with said fastening projections and said adhesive impregnated porous material, whereby said fastening projections penetrate one surface of said veneer sheets and said adhesive fills said cavities between said adjacent sheets.
