Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display board to be attached to an information object such as a utility pole or a railroad sleeper.

[0002]

2. Description of the Related Art Conventionally, telephone poles standing in the city have been subjected to various kinds of information transmission by applying an information object and a sticker to the information pole. Described information is described. Information by telephone poles is simply done via stickers, and information such as the time to replace railroad sleepers and rails is created by creating information (letters, etc.) patterns and spraying paint on it. Creating.

[0003]

Therefore, the information subject is exposed to the wind and rain, and such information may disappear with the passage of long years. Therefore, especially on railway sleepers and rails that require long-term information transmission, various economic problems such as work to rewrite information in the same way at the stage of disappearance and not being able to work when it rains are required. is there. Therefore, the present invention is to provide a display panel which solves such a drawback.

[0004]

According to a first aspect of the present invention, there is provided a display panel in which information is written on a back surface of a synthetic resin display panel, and the display panel is attached to an information-receiving body with an adhesive or the like. Information is not lost due to the weather. Further, in the display panel of the present invention, a concave groove for information is formed on the back surface of the synthetic resin display panel with a laser or the like, a paint is poured into the concave groove, and the display panel is attached to the information receiving body with an adhesive or the like. By sticking, the information does not disappear even if the paint is lost due to weathering or the like. The display panel according to claim 3 is provided on a back surface of the display panel,
Information is formed by a two-dimensional code or a one-dimensional code, and information can be displayed with a small area. According to a fourth aspect of the present invention, there is provided a display panel in which information is written in white ink on a surface of a black FRP (fiber reinforced plastic) display panel, and the display panel is attached to an information receiving body with an adhesive or the like. Since the display panel is made of FRP, it has excellent weather resistance.

[0005]

(First Embodiment) FIG. 1 (A)
FIG. 1 is a diagram showing railroad rails 1 and sleepers 2 as information objects. FIG. 1B shows a display plate 10 to be attached to the sleepers or rails. The display panel 10 is transparent, strong, and has slight irregularities on the back surface 10b.
Synthetic resin plate (for example, FRP (fiber reinforced plastic)
Etc.). Then, on the back surface 10b side of the display plate 10, various information (exchange time, etc.) 11 is written using paint. Therefore, the display panel 10 can read the information 11 from the front side. The use of FRP for the synthetic resin plate is desirable because of its excellent weather resistance.

Then, the back surface 10b of the display panel 10 is
By adhering to the information object 1 (2) such as the rail 1 or the sleeper 2 via an adhesive (epoxy or the like), rain is not inserted on the back side of the display panel 10, and Due to the strong material (FRP), it can withstand impact and does not discolor even by ultraviolet rays. Therefore, the display plate 10
Can be easily formed and can be used almost permanently, which is economical.

(Second Embodiment) In this embodiment, as shown in FIG. 1 (C), a synthetic resin plate (transparent, strong, and having slight irregularities on the back surface) is used. For example, F
(RP etc.) Marking of the concave groove 15 for the information 11 is created in advance on the back surface 10b of the (display panel 10) by a laser or the like. In addition, this marking has a groove 1
There is a method of forming the groove 5 and a method of forming the concave groove 15 only in the character frame. The information 11 can be displayed more clearly by pouring the paint into the concave groove 15, and the back surface 10b of the display plate 10 is attached to the information object 1 such as the rail 1 or the sleeper 2 via an adhesive or the like. When applied to (2), even if the paint disappears, the information can be permanently displayed. Needless to say, if the information can be decoded by the concave groove 15 formed as described above, it is not always necessary to pour the paint.

The back surface 10b of the display panel 10 has
A groove is formed in the one-dimensional code 30A or the one-dimensional code 30B by a laser or the like, and information is displayed by pouring paint into the groove. These two-dimensional code 30A and one-dimensional code 30B are a code reader (not shown).
Can be read through. If the two-dimensional code has a size of about 10 mm × 10 mm and the one-dimensional code has an area of about 10 mm × 20 mm, a sufficient amount of information can be displayed. Therefore, the information 11 in the first embodiment can be used. Can be applied to the margin of the disclosure location. As mentioned above,
These one-dimensional code 30B or two-dimensional code 30A
In this case, even if the display by the paint disappears as in the first embodiment, the information can be read, which is meaningful.

(Third Embodiment) The display panel 10 of the present embodiment uses a black FRP (fiber reinforced plastic) plate having excellent weather resistance.
The information 11 is written on the surface of the black FRP through printing or the like with the white ink which is more obvious than the black FRP (FIG. 1).
(B)). In addition, the color of the ink and the color of the display panel are not limited to the combination of white and black. Next, the manufacturing process of the display panel 10 will be specifically described.
A mold releasing agent is applied to a mold for producing the resin, and a glass chopped strand mat (trade name: # 4501P, manufactured by Asahi Fiberglass Co., Ltd.) is laminated with a black polyester resin, and then the resin is irradiated with ultraviolet rays. After being cured by heating, it is taken out of the mold and manufactured, and then the release agent is wiped off with a solvent or the like.

Next, information (exchange time, etc.) is printed on the surface of the display panel 10 by silk screen printing.
The ink used for this silk screen printing is F
A two-part thermosetting material that adheres well to RP is preferred,
For example, a two-liquid urethane ink (manufactured by Seiko Advance Co., Ltd., trade name: SG429B White, etc.) is used. Then, after printing on the display panel 10, it is dried, and further,
In order to prevent information from being erased, for example, a two-liquid urethane clear hard code agent (manufactured by Seiko Advance Co., Ltd., trade name: SG429R) is applied with a thickness of about 50 μm. And then, by drying,
The display board 10 on which information is described is completed.

When the display panel 10 is used, the display panel 10 is attached to the information-receiving body 1 (2) such as the rail 1 or the sleeper 2 via an adhesive (epoxy or the like) on the back surface of the display panel 10 (see FIG. 1). FIG. 1A). Since this display panel 10 uses FRP (fiber reinforced plastic), it has excellent weather resistance,
It can be used almost forever and is economical. In addition, by writing information in black FRP with white ink, the display plate 10 can be read at night as well as during the day, and is hardly stained because the surface is coated with a hard coat agent. There is a feature that is strong against impact because there is.

The display panel 10 of the present invention can be used in various fields other than the rails and sleepers, such as a utility pole standing in a city to prevent information from disappearing.

[0013]

According to the first aspect of the present invention, since the information is written on the back surface of the synthetic resin display panel and attached to the information-receiving body, the display panel can be simplified and the effect can be improved. .
Further, in the display panel according to the second aspect, even if the paint disappears due to the marking with a laser or the like, the information does not disappear. According to the display panel of the third aspect, information with a two-dimensional code or a one-dimensional code can be formed on the back surface of the display panel with a small area. The display panel according to claim 4 is made of FRP and thus has excellent weather resistance.
