Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a substrate for creating a three-dimensional character for a signboard, and a three-dimensional character obtained by using the substrate.

[0002]

[Prior art]

 Conventionally, as a three-dimensional character for a signboard, a styrofoam plate is machined to make a dial plate main body and a resin layer is coated on the outer side (Jitsuko Sho 39-1904), or foam such as polyurethane. It has been proposed that a colored synthetic resin sheet or film is adhered to the body and cut, and that the surface of the characters and the adhesive for attachment are protected before use (Jitsuko Sho-50-693). Furthermore, one side of the synthetic resin foam is attached to a face plate for makeup, and the other side is attached to a fixing plate made of hard synthetic resin and having a thickness of 0.5 to 2.0 mm. (Jitsuko Sho-60-20138) is available.

However, from these viewpoints, it is complicated to coat the foam cut in the character shape with the resin layer. To solve this problem, there is a product in which a colored synthetic resin sheet or the like is attached to the foam, and then cut into letters for handling.Fixing plates for attachment are also provided on the back of the foam. Some of them are joined, but each has various drawbacks. That is, in the case where a colored synthetic resin sheet or the like for the surface of a character is bonded to a foam, the bonded surface is likely to deteriorate or the dimensions thereof are likely to change. In addition, it is necessary to purchase a standard size object for each color tone, which is problematic in terms of economy and storage of the remaining portion. Even if they are joined each time, it is not preferable in terms of work efficiency. Furthermore, when creating a three-dimensional character, it takes time and effort to create a pre-written original document and apply it to cut it.

In addition, in the example in which the mounting fixing plate is joined to the back surface of the foam, it is said that the entire warp is prevented and screwing is possible. Therefore, the surface plate for makeup is made of hard polyvinyl chloride. A polymethyl methacrylate plate or a laminated sheet of these and a metal plate is used with a thickness of about 2 mm to maintain the flatness, and the fixing plate for mounting is made of a hard material to prevent cracks when screwing. As the synthetic resin, a polyvinyl chloride plate having a thickness of 0.5 to 2 mm is used. Therefore, in addition to the above-mentioned drawbacks, the weight of a three-dimensional character becomes large, and even if the three-dimensional character is joined by an adhesive or fixed with a screw, a case where the three-dimensional character cannot be sufficiently fixed occurs. Further, since a wire saw blade is used for cutting in the step of creating three-dimensional characters, burrs are likely to occur on the cut surface, it takes time and effort to finish, and chips are generated, which is not preferable in the working environment.

Further, to improve these, a synthetic resin sheet is joined to one or both sides of a plate-shaped synthetic resin foam, and the synthetic resin sheet (if there is both sides, one side thereof) is colored. There are laminated three-dimensional characters (utility model registration No. 3003523) in which a synthetic resin film is joined. The synthetic resin foam is made of ethylene-vinyl acetate copolymer and the synthetic resin sheet is made of polyethylene terephthalate. There is. As a three-dimensional character for signboards, it has the advantages of excellent economy, easy character creation, no burrs or chips when cutting characters, and a lighter three-dimensional character obtained. Rays easily enter the adhesive, and the adhesive may peel off due to aging, causing swelling points on the surface of the three-dimensional character due to aging, and it is difficult to achieve perfectness in terms of ensuring flatness.

[0006]

[Problems to be solved by the device]

 In view of the conventional drawbacks, the present invention can be perfected as a three-dimensional character creation material for signboards, especially in terms of securing the flatness of the surface of the three-dimensional character, and it is intended to provide a three-dimensional character with a clean cut end. To do.

[0007]

[Means for Solving the Problems]

 That is, the present invention is a laminated three-dimensional character substrate. First, an aluminum laminate in which a synthetic resin foam sheet is interposed between two aluminum sheets has a coating film on the non-bonding surface and is a plate. -Shaped synthetic resin foam bonded to one surface, and secondly, a rigid synthetic resin sheet bonded to the other surface of the plate-shaped synthetic resin foam of the first laminated three-dimensional character substrate. Thirdly, the above-mentioned aluminum laminate is joined in place of the hard synthetic resin sheet of the second laminated three-dimensional character substrate. By cutting these, a laminated three-dimensional character can be obtained. As a laminated three-dimensional character, a colored synthetic resin film is bonded to the coating surface of these laminated three-dimensional character substrates. As the synthetic resin foam sheet in the aluminum laminate, polyethylene is suitable. The layered three-dimensional characters of the present invention include kanji, kana characters, numbers, alphabets, and various types of figures, symbols, patterns, and the like.

[0008]

[Embodiment of device]

 The use of the aluminum laminate formed by interposing the synthetic resin foam sheet between the two aluminum sheets makes it possible to secure the weight and surface flatness of the laminated three-dimensional character substrate. . In particular, the surface of the sheet is an aluminum sheet with a coating, so the cut surface is clean when using multi-layered three-dimensional characters. And, even if the colored synthetic resin film is not joined to form a laminated three-dimensional character only with the coating film on the surface, the aesthetic appearance can be obtained. Since only aluminum sheets are easily scratched and it is difficult to obtain an aesthetic appearance, these are improved by applying a coating film having a higher surface hardness. It is more economical to join colored synthetic resin films than to increase the number of types of paint film. In this case, white is most suitable as the color tone of the coating film, so that the color tone is not changed by the transmitted light after the colored synthetic resin film is bonded. Light rays do not enter the adhesive layer between the aluminum laminate having the coating film and the plate-like synthetic resin foam, so the adhesive does not deteriorate and the surface flatness changes when laminated solid characters are used. Never. The synthetic resin foam sheet is preferably made of polyethylene because of its light weight and weather resistance, but is not limited to this, but its thickness is about 1.20 to 3.00 mm, and the aluminum sheet is A suitable thickness of each layer is 125 to 200 μm. If the aluminum sheet is too thick, it becomes difficult to cut characters, which is economically undesirable.

The plate-like synthetic resin foam is one that is lightweight and has a three-dimensional appearance, and is made of low-foaming polyethylene, polyvinyl chloride, ethylene-vinyl acetate copolymer (EVA), polyurethane or the like. Although it can be used, when it is used outdoors, a closed-cell foam is preferable because it avoids the absorption of rainwater. These are used within the range that they have appropriate mechanical strength and weather resistance. From this point of view, EVA is optimal, and the thickness when used is 10 to 50 mm.

An aluminum laminate in which a synthetic resin foam sheet is interposed between two aluminum sheets has a coating film on the non-bonding surface and is provided on one surface of the plate-like synthetic resin foam. The first laminated three-dimensional character board that is bonded is lightweight, but due to the shape and thickness of the three-dimensional character and the environment in which it is used, aluminum expands and contracts due to the expansion and contraction of the plate-like synthetic resin foam in summer and winter. Since the laminated body may be curved or bulged, in order to prevent this warpage, a hard synthetic resin sheet is formed on the other surface of the plate-shaped synthetic resin foam forming the bottom of the first laminated three-dimensional character substrate. It is better to join.

A hard synthetic resin sheet to be used as a bottom plate of a second laminated three-dimensional character substrate, in which a hard synthetic resin sheet is bonded to the other surface of the plate-shaped synthetic resin foam of the first laminated three-dimensional character substrate, In particular, the purpose is to prevent warpage of the whole, to secure the flatness of the surface further, and to emphasize the aesthetic appearance of the character surface, so long as it has appropriate mechanical strength and weather resistance. Often, polyvinyl chloride, polyethylene terephthalate, polymethylmethacrylate, etc. can be used. Polyvinyl chloride is ideal because it is economical and has excellent rigidity and weather resistance. Its thickness is about 500μ. Its rigidity has the effect of strengthening the fixation when adhering the laminated three-dimensional characters to the base or when fixing with screws.

Even with the second laminated three-dimensional character board, the plate-like synthetic resin in the summer and winter seasons differs from the first laminated three-dimensional character board depending on the usage pattern and severe environmental changes, as in the case of the first laminated three-dimensional character board. The aluminum laminate may still bend and swell as the foam expands and contracts. If it is necessary to prevent this warpage completely, the hard synthetic resin for the second laminated solid character board should be used. Instead of a sheet, it is better to use an aluminum laminate in which a synthetic resin foam sheet is interposed between two aluminum sheets. Since the plate-like synthetic resin foam is bonded to both sides with the same mechanical strength and thermal expansion, the third laminated three-dimensional character substrate does not warp. However, when using this product, it is necessary to give due consideration to economic efficiency.

As a colored synthetic resin film for cosmetics, polyvinyl chloride film is suitable for outdoor use in consideration of weather resistance, but polymethyl methacrylate film can also be used. Nowadays, a so-called marking film of various colors is widely available on the market, and can be arbitrarily selected. Since the adhesive is previously applied to this via a release paper, the joining operation becomes easy when using. The thickness is not particularly limited, but is preferably about 50 to 90 μm. As another case, an attempt was made to directly bond this type of colored synthetic resin film to the plate-shaped synthetic resin foam, but since the surface of the plate-shaped synthetic resin foam was rough, the bonding was not possible. It has been proved that it is not suitable for practical use because the strength is weak and it is easy to peel off, and the surface finish is not beautiful even after joining.

When the colors of the coating films on the various laminated three-dimensional character substrates as described above are used as they are, the laminated three-dimensional character is obtained by directly cutting into the character shape.

When the color of the coating film of the laminated three-dimensional character board is not used as it is, the colored synthetic resin film of a predetermined color may be bonded to the laminated three-dimensional character base plate and then cut into predetermined characters, but peeling may be performed. A predetermined character shape is cut from a colored synthetic resin film with paper using a cutting system such as various typefaces with a commercially available computer, and then it is joined to a laminated three-dimensional character board to further form a character outline. Along with this, a laminated solid character can be obtained by cutting with a saw blade or a thread-shaped blade. This is more efficient. In the above-mentioned laminated three-dimensional character creation, burrs do not occur on the cut surface, and the amount of chips is extremely small. The layered three-dimensional character obtained in this way has a sharp cut and has an exceptional aesthetic appearance.

When fixing the laminated three-dimensional character, a double-sided tape for adhesion or an adhesive is used, a screw is used, or as a metal fitting, "a metal base plate having a plurality of screw holes, A hook-shaped support piece obtained by cutting out the inside is bent to stand upright, and a support piece having a detachment prevention piece bent like a hook obtained by cutting out the inside thereof can be used. it can.

【Example】

 Hereinafter, the present invention will be described in more detail with reference to examples. FIG. 2 shows a second laminated three-dimensional character board. The whole structure uses a low foam EVA having a thickness of 30 mm as the plate-shaped synthetic resin foam 2, and a synthetic resin foam sheet 7 having a thickness of 1.25 mm of polyethylene foam sheet on one surface thereof. -A sheet of aluminum is coated with 125 μm aluminum sheet 6 on both sides, and one side of the sheet is coated with a white coating with a polyester coating. The non-solvent type adhesive is used for bonding, and a polyvinyl chloride having a thickness of 500 μ is bonded to the other surface as a hard synthetic resin sheet 3. The white coated surface is covered with a peelable protective film, and the size of the laminated three-dimensional character substrate is 910 mm × 1820 mm.

As shown in FIG. 5, when a layered three-dimensional character having a green surface is prepared, as a colored synthetic resin film 5 for peeling, peeling is performed on the coating surface of the layered three-dimensional character substrate obtained as described above. A 90 μm thick green soft polyvinyl chloride film (trade name: Graphtac, sold by Pros Co., Ltd.) with a paper coating adhesive is cut into English letters A in advance using the above-mentioned cutting system and joined. .

Then, by cutting this along the contour of the character, a laminated three-dimensional character of the English character A 1 is obtained as shown in FIG. Comparing this with a conventional fixing plate for mounting, the weight is reduced by about 20%. The laminated solid letters are fixed to the base with double-sided adhesive tape.

[0020]

[Effect of device]

 The laminated three-dimensional character substrate of the present invention has excellent surface flatness, so if the coating color remains the same or if a colored synthetic resin film is bonded to the coating surface to form a laminated three-dimensional character, the character surface is finished neatly. Since it is lightweight, it can be easily fixed to the base. When colored synthetic resin films are joined to create a laminated three-dimensional character, there is no waste of material and it is extremely economical. Characters can be easily cut, there is no burr on the cut surface, and the cut end is clean. In addition, a working environment is good because almost no cutting chips are generated during cutting.
