Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing cabinets used in televisions, stereos, etc.

BACKGROUND ART Recently, cabinets have been frequently used in which a synthetic resin film sheet with various patterns printed on its surface is adhered to a substrate made of plywood or the like, and the substrate is bent appropriately.

On the other hand, recently, cabinets for televisions, etc., have come to be required not only to fulfill their original purpose and function, but also to have aesthetic elements as interior decoration items.

Therefore, various improvements have been made to printed patterns, shapes, etc.

However, since general cabinets are constructed by bending the substrate as described above, the bent edges tend to be too sharp and lack a sense of solidity.

To explain the conventional manufacturing method in more detail, Fig. 1 shows a stereo speaker box, which has four sides 1, 2, and 3.
, 4 are composed of a substrate 5, a cloth 7 is stretched on the front surface 6, and a speaker is housed inside.

Printed synthetic resin film sheets are adhered to the surfaces of the four substrates 1, 2, 3, and 4.

To manufacture such a cabinet, a synthetic resin film sheet 8 is placed on a substrate 5 made of plywood as shown in FIG.
Prepare a suitable length of the material to which the material is pasted, form a V-shaped bending groove 10 as shown in the figure in the intended bending area 9 to a depth that reaches approximately the pasting surface 11, and then Apply adhesive and bend to form the cabinet.

Therefore, although it is extremely mass-produced, the bent ridge 13 has no roundness and the overall feel lacks solidity.

The present invention has been made to eliminate the above-mentioned drawbacks, and an object of the present invention is to provide a method for manufacturing a cabinet or the like that has a sufficiently solid feel despite its simple configuration.

The details of the present invention will be explained below with reference to one embodiment shown in the drawings.

Note that the same parts are denoted by the same reference numerals, and detailed explanations will be omitted.

Similar to the conventional example shown in FIG.
(See FIG. 4) on the back surface 14 of the substrate 5, as shown in FIG.
Leave a gap S of about mm to 5 mm.

Next, a circular groove 15 substantially in contact with the adhesive surface 11 is formed along the bent groove 10 using a round cutter.

Next, the substrate 5 is bent until the side surfaces 12, 12 of the bending groove 10 are brought into close contact with each other to form a cabinet.

At this time, the synthetic resin sheet 8 is stretched while being appropriately drawn toward the bending center, so that a ridge portion 13 having a considerably large roundness can be obtained as shown in FIG.

As detailed above, the manufacturing method of the present invention involves forming a bending groove so that the bottom of the V-shaped bending groove is located 2 mm to 5 mm inward from the adhesion surface of the synthetic tree sheet, and then adhering the synthetic tree sheet. To inexpensively provide a cabinet or the like that has sufficient weight because a circular groove reaching the surface is provided and the product is bent, so there is no center of bending on the adhesive surface and a sufficiently large roundness can be formed at the ridge. Can be done.

In addition, the above S has no effect if it is less than 2 mm, and if it is 5 mm or less,
Exceeding this is not preferable because it will have an adverse effect on the synthetic resin sheet.

Furthermore, although the present invention has been described with respect to cabinets for televisions, stereos, etc., it is not limited thereto, and it goes without saying that this type of furniture and furniture in general may be used.

Claims (1)

[Claims] 1. In a manufacturing method for cabinets, etc., in which a V-shaped bending groove is formed on the back side of a substrate with a synthetic resin sheet attached to the surface, and the substrate is bent along the bending groove, the synthetic resin sheet is attached to the surface of the substrate. forming the above-mentioned bending grooves leaving a gap of 2 mm to 5 mm before the surface of the synthetic resin sheet, and forming arcuate grooves that are in contact with the circular arc shape of the synthetic resin sheet and opening into the bending grooves along the bending grooves; and a step of bending the substrate until the side surfaces of the bending groove are in close contact with each other.
