Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a decorative board used for an operation board, a name plate, a badge, a sheet, etc. of a desktop calculator.

(Prior Art) Various types of decorative boards have been proposed in the past, but all of them basically display patterns, characters, symbols, etc. on one side of the outer surface of the base material in a flat manner. It was printed on.

(Problems to be solved by the invention) However, in the case of the conventional decorative board, since the display of patterns, characters, symbols, etc. is simply printed on the base material, it lacks a design appearance. There was a problem.

The present invention was devised in view of the above-mentioned problems, and its purpose is to use a composite material made of metal and plastic, and by subjecting the composite material to simple processing, to achieve an excellent design appearance. Our goal is to provide decorative boards with high decorative value.

(Means for Solving the Problems) The decorative board of the present invention is constructed as shown in the drawings of the embodiment, and uses a plastic film 1 having a metal surface 1a on the outer surface of one side. While forming a colored layer 2 on the corresponding part,
A metal piece 4 is integrally bonded to the colored layer 2 side of the film 1 via a transparent adhesive layer 3, while a part of this metal piece 4 is attached to a portion corresponding to the colored layer 2.
A decorative board characterized in that a display 4a penetrating both the front and back surfaces of the metal piece 4 is formed.

(Function) Thus, the colored layer 2 is exposed to the outside from the marking 4a of the metal piece 4 through the adhesive layer 3, that is, the marking 4a of the metal piece 4 is colored by the colored layer 2 and exposed to the outside. Furthermore, from the outer periphery of the metal piece 4, the metal surface 1a of the plastic film 1 is exposed to the outside through the adhesive layer 3, and the color of the metal surface 1a and the color of the metal piece 4 are Due to the color of the colored layer 2 exposed from the display 4a, the decorative board has a good design appearance and the decorative value of the board is increased.

(Example) The decorative board according to the present invention will be described below with reference to the examples shown in the drawings.

Figure 1 shows an operation board for a desktop calculator as an example of a decorative board, with a frame 5 surrounding the outer periphery on the outer surface.
A large number of rectangular metal pieces 4 serving as operation keys are provided inside the frame 5, and displays 4a such as numbers and symbols are formed through each metal piece 4. It is formed as follows.

That is, as shown in FIG. 2, a composite material is used in which a metal surface 1a such as an aluminum vapor-deposited surface is integrally formed on one outer surface of a plastic film 1.
The display 4a on the metal surface 1a side of this composite material
Colored layer 2 made of colored film is placed on the corresponding part of
At the same time, the metal surface 1a of the film 1
A metal plate is integrally bonded to the side via a transparent adhesive layer 3.

Then, by etching the metal plate, a frame 5 surrounding the outer periphery of the aforementioned operation board is formed.
In addition, each of the metal pieces 4 is formed to remain in the frame 5, and each metal piece 4 is provided with the display 4a so as to pass through both the front and back surfaces of each metal piece 4.
form.

With the above configuration, the colored layer 2
Via the adhesive layer 3, the display 4a of the metal piece 4 is exposed to the outside, that is, the display 4a is colored by the colored layer 2 and exposed to the outside, and the outer periphery of the metal piece 4 is From this, the metal surface 1a of the film 1 is exposed to the outside through the adhesive layer 3, and therefore the color of the colored layer 2 exposed to the outside from the display 4a of the metal piece 4 and the metal piece Due to the metallic color of the metal surface 1a of the film 1 exposed to the outside from the outer periphery of the film 4,
This improves the appearance of the operation board.

Further, as mentioned above, the metal surface 1a of the film 1
By providing the adhesive layer 3 on the side, the metal surface 1a is protected by the film 1 and the adhesive layer 3 in a sandwich pattern, so that the metal surface 1a does not need to be subjected to a separate protection treatment. The metal surface 1a can be protected.

In the embodiment, the display 4a of the metal piece 4 is displayed on the metal surface 1a side of the plastic film 1.
In providing the colored layer 2 in the corresponding part,
Although a colored film is used, the present invention may use colored ink and apply the ink to the portion of the film 1 corresponding to the display 4a by printing means such as screen printing.

The plastic film 1 can also be provided with its metal surface 1a facing the outside. In this case, the metal surface 1a is subjected to a protective treatment such as a back coat, and the film 1 is made of a transparent material. The metal surface 1a is exposed from the outer periphery of the metal piece 4 through the film 1 and the adhesive layer 3.

Further, in the decorative board of the present invention, as shown in FIG. It is also possible to form a large number of hairlines b extending vertically orthogonally to the hairline a on the outer surface of the surface 1a, and in this case, each of the hairlines a and b may be contrastingly intersecting to the outside. This can further enhance the appearance.

Incidentally, in the above-mentioned embodiment, the operation board of a desktop calculator has been described, but the decorative board of the present invention is not limited to the above-mentioned embodiment, and can be applied to name plates and the like.

(Effects of the invention) As explained above, the decorative board of the invention has
A plastic film 1 having a metal surface 1a on the outer surface of one side is used, a colored layer 2 is formed on the display corresponding portion of the film 1, and a transparent adhesive layer 3 is provided on the colored layer 2 side of the film 1. While the metal pieces 4 are joined together, a mark 4a penetrating both the front and back sides of the metal piece 4 is formed in a part of the metal piece 4 corresponding to the colored layer 2. The colored layer 2 is exposed to the outside through the display 4a, that is, the display 4a of the metal piece 4 is colored by the colored layer 2 and exposed to the outside, and from the outer periphery of the metal piece 4, the Since the metal surface 1a of the film 1 is exposed to the outside, the decorative board has a good design appearance, and the decorative value of the board can be significantly increased.
