Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a cabinet having a green surface on its front end surface.

Conventionally, in cabinets such as TVs, when the surface of the corner part, which is the joint part between the husband board and both side boards, is formed into an arcuate surface, the back side of the rectangular board with Nikkei sheet pasted on the surface. This is done by carving a U-shaped groove or a comb mark in the middle direction and bending it through the groove, but the cabinet body formed in this way has the end face of the core material O on the front end face of the cabinet body. Because it is unsightly when exposed, most of the wood ends are covered with other molded products.

For example, in order to make a cabinet with an I8 bonito surface green, an appropriate IQ Ryu sheet is glued to the end surface, and the outer periphery is processed to remove holes with a knife or the like along the cabinet body.
Seam with the cabinet body. There is a method of applying touch-up (coloring) with paint etc., but according to this method,
This method requires a large number of manufacturing steps and has the drawback that touch-up protrusions may occur, resulting in an unsightly appearance. Another method is to form a gate-shaped edge member by framing a rod-shaped single piece of wood, curve the corners, and then paint it and attach it to the front end face of the millet net, but this method requires a lot of man-hours. There is a disadvantage that the number of parts increases significantly and the cost becomes very high.

Furthermore, each of the above-mentioned methods also has the problem that it is difficult to form the internal width of the cabinet to a predetermined dimension.

That is, in the case of the above-mentioned method of pasting wood with a decorative sheet, when the cabinet body is bent and formed, the side slopes on both sides of the corner part are freely displaced and dimensional changes occur, and this is regulated. For this purpose, you must use an inner width gauge, etc.

Furthermore, even when using the above-mentioned twill member made of a single wood material, the single wood material is generally prone to warping and distortion due to manipulation, so it is difficult to assemble a cabinet using this twill member in place of a gauge. However, it had the same disadvantage of poor dimensional stability as described above.

SUMMARY OF THE INVENTION In view of these conventional problems, an object of the present invention is to provide a method for manufacturing a cabinet with a surface edge that requires fewer manufacturing steps, is suitable for mass production, and has extremely high dimensional stability. For this reason, the present invention forms an end frame using a rod-shaped body formed by bending and bonding a decorative board through a V-shaped groove, thereby obtaining an end green frame that is free from distortion due to warping or pitting. V from the bottom surface at two locations along the length of the rod-shaped body.
By carving a V-shaped groove and bending it at right angles through the V-shaped groove to form the portal-shaped end edge frame, the end edge frame can be obtained with a small number of manufacturing steps and a method suitable for mass production. In addition, by assembling a cabinet using the thus obtained green frame with high dimensional accuracy as an inner width gauge, it is possible to efficiently manufacture a cabinet with good dimensional stability. By forming a gate-shaped cabinet body using IQ plate material having the same thickness as the height of this stepped portion, and attaching the stepped portion of the end edge frame to the inner surface of the front end of this cabinet body. To provide a method for manufacturing a cabinet with a beautiful surface edge, since the two parts are joined with high precision so that there is no variation in dimensions, and the outer peripheral surfaces thereof are formed on the same plane.

Embodiments of the present invention will be described with reference to the drawings.
