Description

[Detailed Description of the Invention] The present invention relates to a cabinet for audio products constructed by bending a single board.

Traditional wood products have generally been made of natural wood.

However, due to the decline in natural wood, natural wood has become expensive, and it has become impossible to use natural wood in cabinets and the like for audio products that are mass-produced.

Therefore, as a conventional method of making the cabinet of an audio product appear as if it were made from natural wood, the cabinet of an audio product was constructed by bending a single board.

This method will be explained below.

In this method, as shown in Figs. 1 and 2, a sheet 2 made of soft vinyl chloride having wood grains in a certain direction is attached to the surface of a single wooden board 1, and the board 1 is slightly Each side has a V-shaped groove 3 with a 90-degree cross section, and a front side plate 5 and a rear side plate 6 are placed on the front, rear, left, and right sides of the player board 4 with the groove 3 separated.
, the left side plate 7 and the right side plate 8 are continued and cut out as a set.

Therefore, each side plate 5. 6. 7. 8 at right angles inward as shown in Figure 3, and each side plate 5, 6 has a v of 7.8
The surfaces of the grooves are brought into contact and the abutted parts are joined.

In the player cabinet thus obtained, the grain direction of the left and right side plates 7, 8 is continuous with the player board 4.

Therefore, it was found that the product was formed by cutting and bending a single plate to which a vinyl chloride sheet was attached, and it had the drawback of giving a different feel from a high-quality product.

That is, when manufactured from natural wood, the wood grains of the top plate and the left and right side plates are perpendicular to each other, and the wood grains of the top plate and the front and rear side plates are parallel, as shown in FIG.

Therefore, by looking at the direction of the wood grain of the top plate and the left and right side plates, it was possible to easily determine whether the cabinet was made of natural wood or not.

In order to eliminate this drawback, parts other than the player board are made of plywood, particle board, etc., and after assembly,
Attach a synthetic resin sheet with wood grain printing or a thin board with natural wood grain to the side surface.

A method called kiguchi pasting is used.

Although this method can give a sense of luxury, it not only cannot be cut from a single board, but also makes the wooden structure quite complicated when assembled.

In addition, the work efficiency is poor due to the paper work of sheets or thin plates, and the use of a special machine called an automatic border pasting machine is expensive.

Further, there were drawbacks such as the structure and shape being easily limited.

This invention creates an appearance in which the grain directions of the top plate and the left and right side panels are perpendicular to each other by cutting a single board and bending it.In other words, the wood grain direction is similar to that of a cabinet made from natural wood. By forming it, you can give it a luxurious feel as if it were made from natural wood, and
It is an object of the present invention to provide a cabinet for audio products that can be manufactured easily and at low cost.

An example in which the present invention is implemented in a player cabinet will be explained with reference to the drawings.

As shown in FIGS. 4 and 5, first, a sheet 2 made of synthetic resin such as soft vinyl chloride is printed on the surface of a long wooden board 1 so that the grain direction is in the longitudinal direction. Paste.

Next, two V-shaped grooves 3 are formed in the upper and lower lateral force directions along the longitudinal edge of the board 1 along the front and rear widths of the player board 4, and two V-shaped grooves 3 are formed in the horizontal direction and the front and rear widths of the player board 4. The player board 4 and the front, rear, left and right side plates 5°6, 7. Section 8.

The groove 3 is formed using a cutter blade having a V-shaped cutting edge or a chain saw crossed in a V-shape to cut only a portion of the plate material 1, and each plate is held in a continuous state by the sheet 2.

Next, each point a-S-b-C-d-e and f-g-h-i
Cut the sheet 2 along the line of the tip of the groove connecting -j with a knife or a pre-4 cutter.

Therefore, as shown in FIGS. 6 and 7, the player board 4, the front side plate 5 and the rear side plate 6 adjacent to the player board 4 with the groove 3 in between, and the grooves on the rear side plate 6 and the front side plate 5, respectively. A set of player cabinets having a left side plate 7 and a right side plate 8 adjacent to each other with 3a and 3b separated from each other can be cut out in the unfolded state in a two-character shape.

Similarly, by cutting the sheet 2 along the tip line of the groove connecting 'i and 1'm~n~0~p to g''', the unfolded state of another set of player cabinets can be cut out. can.

Next, the front side plate 5 and the rear side plate 6, together with the right side plate 8 and the left side plate 7, are bent at right angles to the player board 4 through the groove 3 inwardly, that is, to the back side.

Subsequently, the left side plate 7 and the right side plate 8 are bent inwardly at right angles to the rear side plate 6 and the front side plate 5 through the grooves 3a and 3b, and the left side plate 7 is bent.
The side edges of the right side plate 8 are brought into contact with the side edges of the player board 4, the front side plate 5, and the rear side plate 6, respectively, and the abutting portions of the left side plate 7 and the front side plate 5 and the abutting portions of the right side plate 8 and the rear side plate 6 are Temporarily fasten the joint with a locking pin.

Thereafter, by fixing each of the abutting portions with an adhesive, a player cabinet can be obtained in which the grain directions of the player board 4 and the left and right side plates 7, 8 are perpendicular to each other, as shown in FIG.

In the above embodiment, the left side plate 7 and the right side plate 8 are arranged and cut out on the opposite sides of the rear side plate 6 and the front side plate 5, respectively.
The right side plates 7 and 8 may be placed on both sides of either the front side plate 5 or the rear side plate 6 and cut out.

Further, although the present invention is particularly effective for creating an image of a cabinet constructed from a single thick plate, it can also be used for speaker boxes whose baffle plates, top plate, side plates, and base plate are finished with wood grain finish.

Furthermore, when using natural wood grain decorative boards, conventionally the side surfaces had to be glued to the wood edges, but now we can apply wide adhesive tape to the natural wood grain decorative board surface on the back side where the cut grooves are formed. By performing the (1) cut with the arrangement as described above, even in the case of a natural wood grain decorative board, it is possible to make the wood grains of the top plate and side panels orthogonal.

As is clear from the above, according to the present invention, a side plate is placed on the side plate adjacent to the top plate from a single plate to which a sheet-like material with wood grain is attached to the surface, and further in a direction orthogonal to the top plate. When assembled, the wood grains of the top plate and the left and right side panels can be made perpendicular to each other without using the traditional wood-grain method, giving it a luxurious feel while also being easy and inexpensive. It has the advantage of being able to be manufactured in
