Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display plate for three-dimensional characters and the like, and more particularly to a display plate having flexibility.

[0002]

2. Description of the Related Art Conventionally, there is known a display plate in which various kinds of characters, figures, patterns, etc. are printed by printing on the surface of a base made of a flexible synthetic resin such as soft polyvinyl chloride resin. Was there. Such a display plate is used for a beginner's mark for driving a car, stationery such as a calendar and a drawing tool, and various teaching materials.

[0003]

However, since the conventional display plate has a flat display, the display may be difficult to see due to the reflection of light depending on the viewing angle, and the appearance may be difficult to see, or the appearance may be poor. However, there are various problems such as the fact that there are many restrictions, and there is a problem that there are many restrictions on the applications due to these problems.

The present invention has been made in view of the above problems, and is a three-dimensional character in which the display is made three-dimensional and the visibility of the display and the ease of leaving an impression are improved, and moreover, a high-quality appearance can be obtained. It is an object of the present invention to provide such a display plate and a method for manufacturing such a display plate.

[0005]

A display plate for three-dimensional characters or the like according to the present invention comprises a flexible sheet-like base layer and a synthetic resin-made flexible sheet-like surface layer laminated and integrated on the base layer. And a flexible display made of synthetic resin that represents a three-dimensional character or the like that is high-frequency heat-sealed on the surface layer.

According to a second aspect of the present invention, there is provided a method for producing a display plate for three-dimensional characters, etc., wherein the surface layer of the flexible sheet-like laminate comprising a sheet-like base layer and a sheet-like surface layer made of synthetic resin is provided with letters, etc. Place a mold of a predetermined thickness having an opening forming the mark of No. 3, and bury a synthetic resin that exhibits flexibility in a cured state in the above-mentioned opening of the mold, and heat the high-frequency heat fusion of the embedded synthetic resin to the surface layer. It is a thing.

[0007]

According to the display plate of the first aspect of the present invention, since the display is performed by the display body showing a three-dimensional character or the like, it is unlikely that the display layer is difficult to see due to the reflection of light by the surface layer. Since the display is three-dimensional, it is easy to leave an impression and the appearance is also enhanced.
Moreover, even though the display is three-dimensional, since the display body, the surface layer, and the base layer are all flexible,
The display plate itself is flexible and easy to adapt to any shape. Further, since the surface layer and the display body are integrated by being fusion-bonded with each other by high-frequency heat, even if the display plate is bent, no interfacial separation occurs between them.

According to the manufacturing method of the display plate of the second aspect, the display formed by the opening of the mold is three-dimensionally formed on the surface layer of the sheet-shaped laminate. For this reason, compared with the method of creating the display plate by separately creating cut characters and pasting them on the surface layer, it is possible to manufacture the display plate efficiently and inexpensively, without requiring skill.

1 is a perspective view of a display plate A according to an embodiment of the present invention, and FIG. 2 is an end view of the display plate A.
Reference numeral 1 is a base layer, 2 is a surface layer, and 3 is a display body.

The base layer 1 needs to be flexible and sheet-shaped. Although a so-called plastic magnet in which a magnetic powder such as ferrite is mixed in polyvinyl chloride resin is used for the base layer 1, other materials such as leather, rubber, synthetic resin, and ferrite are used for the base layer 1. A so-called rubber magnet or the like in which such a magnetic powder or granular material is mixed with rubber can be used. In particular, the base layer 1 made of the above-mentioned plastic magnet in which polyvinyl chloride resin is mixed with magnetic powder particles.
Has excellent chemical resistance and moldability, and has the advantage of being inexpensive.

The surface layer 2 needs to be a flexible sheet made of synthetic resin. The surface layer 2 is laminated and integrated with the base layer 1 by an adhesive or high frequency heat fusion.
A sheet made of polyvinyl chloride was used as the surface layer 2 of the example, and was laminated and integrated by high-frequency heat fusion with the base layer 1 made of the above-mentioned plastic magnet in which magnetic powder particles were mixed in polyvinyl chloride resin. Therefore, the base layer 1 and the surface layer 2 are integrated for that reason, and there is no fear of peeling at the interface between them. The surface layer 2 is thinner than the base layer 1. And, although the surface state of the surface layer 2 has a luster, this may be a matte state provided with fine embossing.

The display body 3 is formed by three-dimensionally applying kana, katakana, kanji, alphabets and various figures and patterns with a flexible synthetic resin. In the embodiment, the display body 3 is made of polyvinyl chloride resin. Is used. The display body 3 is integrated with the surface layer 2 by high-frequency heat fusion. Therefore, there is no concern that the surface layer 2 made of polyvinyl chloride resin and the display body 3 will peel off at the interface.

In the above, since the base layer 1, the surface layer 2 and the display body 3 are all flexible, this display plate A
Can be bent into any shape without difficulty. Therefore, the display plate A is easily adapted to any shape. The flexibility of the base layer 1, the surface layer 2, and the display body 3 is
It is desirable that the display plate A has a waist strength that does not cause wrinkles on the surface when the display plate A is bent. When the display plate A is attached to various materials, the display layer A whose base layer 1 is made of leather, rubber, synthetic resin, or the like is sewn or bonded to the material. It can be mounted without difficulty on not only flat surfaces or curved surfaces such as glass but also materials such as children's clothing and jeans whose shape is constantly changing. Further, regarding the display plate A in which the base layer 1 is made of the above-mentioned plastic magnet or rubber magnet, if the surface to be mounted is a magnetic body like a car body, the base layer 3 is attracted to the surface by magnetic force. By doing so, there is the convenience that it can be attached.

Further, according to the display plate A, since the display is three-dimensionally displayed, not only is it inexpensive and a high-quality appearance is obtained, but it is also easy to see and memorable. These items of appearance appear more remarkably by appropriately selecting the surface color of the surface layer 2 and the color of each display by the display body 3. Furthermore, if the surface of the surface layer 2 is in a matte state, it becomes difficult to reflect light, and thus the three-dimensional display by the display body 3 becomes easier to see. Further, the above-mentioned plastic magnet for the base layer 1 and the polyvinyl chloride resin for the surface layer 2 and the display 3 have excellent chemical resistance due to the characteristics of the polyvinyl chloride resin.

Next, a method of manufacturing the display plate A will be described. The surface layer 2 of the flexible sheet-like laminate 4 composed of the base layer 1 and the surface layer 2 and the mold 5 shown in phantom are overlapped. In addition, a synthetic resin that exhibits flexibility in a cured state, such as polyvinyl chloride resin, is embedded in the opening 6 formed by forming an indication such as characters on the mold 5. Then, after curing the resin, the interface between the resin and the surface layer 2 is subjected to high-frequency heating to integrally fuse. By doing so, the display body 3 representing the characters, figures, designs, etc. formed by the openings 6 is integrally provided on the surface layer 2. Further, when the surface layer 2 and the synthetic resin embedded in the opening 6 are subjected to high-frequency thermal fusion as described above, the resin of the surface layer 2 and the synthetic resin embedded in the opening 6 are integrated without a boundary. Therefore, interface peeling does not occur at that portion. After performing high-frequency heat fusion, the mold 5 is removed.

When this manufacturing method is adopted, it is desirable that the synthetic resin of the surface layer 2 and the display body 3 is the same synthetic resin, for example, polyvinyl chloride resin. There is an advantage that the integration by fusion is performed extremely well and there is no fear of interfacial peeling. Even if different kinds of synthetic resins are used, similar effects can be obtained as long as they are compatible with each other.

[0017]

According to the display plate for three-dimensional characters or the like according to the first aspect of the present invention, it is possible to perform a display that is easy to see and is likely to leave an impression of appearance, and that is elegant. In addition, the display does not easily disappear even if wear occurs. And since the display plate is flexible and easy to bend, it is easy to adapt to any shape, so it can be easily attached to not only flat surfaces but also curved surfaces and surfaces whose shapes change constantly, increasing versatility. effective. Therefore, it can be particularly suitably used for a display attached to various products and a one-point mark.
Further, since the interface between the surface layer and the display body is not separated, the service life is extended.

According to the method for manufacturing a display plate for three-dimensional characters according to the second aspect of the present invention, even in the case of displaying complicated characters, figures, patterns, etc., these can be three-dimensionally and accurately formed on the surface layer. Can be performed easily, inexpensively and efficiently without requiring skill.
