Abstract

PROBLEM TO BE SOLVED: To make the presence of an indication part such as character clearly recognizable and ensure safety by sticking a light reflecting sheet or applying a light reflecting coating material to a position which never shields a recessed groove having a mark or character engraved therein when an indicator body is seen from the surface side. SOLUTION: A resin plate such as polymethyl methacrylate, polycarbonate or polystyrene under a specified condition in which a red fluorescent coloring matter is dispersed is used to provide an indicating character 3 on the reverse side of an indicator body 2 by engraving a recessed groove 4. On the surface side or reverse side of the indicator body 2, a light reflecting sheet is stuck, or a light reflecting coating material is applied to a position which never shields the recessed groove 4 when the indicator body 2 is seen from the surface side. Otherwise, a reflecting layer reflecting toward the surface side may be provided. The cut surface of the recessed groove 4 is conspicuously lighted with a luminous intensity stronger than the light received by the indicator body 2 to provide the effect of attracting much attention, and the safety is improved.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a sign such as a safety sign, a warning sign, a guide sign, a traffic sign and a guide sign.

[0002]

2. Description of the Related Art Conventionally, as a display device of this type, a neon lamp, an electric sign using a neon tube, an electric sign such as a fluorescent lamp, an electric sign such as an illumination signboard using an ordinary lamp, a reflective adhesive tape, a reflective adhesive sheet, etc. Reflective type, fluorescent paint, and luminous type using luminous paint are known.

[0003]

The electric type described in the above-mentioned prior art is economically unfavorable because it requires facility costs such as electric power equipment and incidental equipment and maintenance costs such as electricity bills, and is of a reflective type. And the light-emitting type does not have a function of receiving ambient light rays, direct light rays, and diffused light rays for densification, and is not so strong in shining light.

It is an object of the present invention to provide a display device such as a signboard, a pointing board, etc., which does not require power and has a strong power to make it noticeably shine.

[0005]

In order to achieve the above object, the label according to the present invention is a polymethylmethacrylate in which fluorescent dye 1 such as a fluorescent dye or a fluorescent pigment is dispersed, a polycarbonate, or a polystyrene under specific constraint conditions. The sign main body 2 is made of a transparent resin plate, and the sign main body 2 is provided by engraving the groove 4 on one or both sides of the sign main body 2. Alternatively, on the back surface, a reflection layer 5 that reflects toward the front side by attaching a light reflection sheet or applying a light reflection paint to a portion that does not hide the concave groove 4 when the sign body 2 is viewed from the front side. , 6 are provided, and on the front surface or the back surface of the sign main body 2, a portion of the sheet where the concave groove 4 is not hidden when the sign main body 2 is viewed from the front side is provided. The colored layers 7 and 8 that develop color toward the front side are provided on the edge of the sign body 2 by attaching a light reflecting sheet or applying a light reflecting paint to the inside. A reflection layer 9 that reflects the light is provided, and a light-shielding layer 10 is provided on the edge surface of the sign body 2 by attaching a sheet or applying a paint.

[0006]

In the present invention, the marker body receives a peripheral light beam, a direct light beam and a diffused light beam on a surface other than the cut surface of the concave groove 4, converts the wavelength into a fluorescent light, and converts the fluorescent light into a fluorescent light according to the law of total reflection. The majority (about 70 to 80%) is guided to the cut surface of the concave groove 4 to make it dense, and the cut surface of the concave groove 4 is made to shine prominently with a light intensity higher than the received light, and is exposed to the outside. Strengthening the power to show,

Further, in the present invention, the light shielding layer 10 provided on the edge surface of the sign body 2 escapes from the edge surface of the sign body 2 when the above fluorescence is guided according to the law of total reflection. By shutting out the rays of light to further increase the density,

In the present invention, the reflective layer 9 provided on the edge surface of the sign body 2 escapes from the edge surface of the sign body 2 when the above fluorescence is guided according to the law of total reflection. The function of shutting out and reflecting the rays of light to be performed further enhances the above-mentioned densification,

In the present invention, the colored layer 8 provided on the back side of the sign body 2 prevents light rays that escape from the back surface of the sign body 2 when the above fluorescence is guided according to the law of total reflection. Shut out to increase the above densification,

In the present invention, the reflection layer 6 provided on the back side of the sign body 2 prevents light rays that escape from the back surface of the sign body 2 when the above fluorescence is guided according to the law of total reflection. The function of shutting out and reflecting is further enhanced to further increase the above-mentioned density.

In the present invention, the reflective layer 5 or the colored layer 7 provided on the front surface of the sign body 2 has the recognizability by the force that each of these layers 5 and 7 shows to the outside and the concave groove 4 as a display portion for characters and the like. The difference from the observability due to the external force is made noticeable.

[0012]

Since the sign according to the present invention has the above-mentioned structure, the concave groove 4 forming the display portion such as a symbol, a character, a picture, a pattern, etc. with a light intensity higher than the light beam received by the sign body 2. The cut face shines conspicuously, and the presence of the display part such as the character can be strongly and clearly recognized by nearby people, and the effect of being noticeable is extremely large.
Further, as described above, the marker body 2 in which the cut surface of the concave groove 4 shines is made of transparent plastic such as polymethylmethacrylate, polycarbonate in which a fluorescent dye is dispersed, or polystyrene under specific constraint conditions. It has such an excellent effect that it completely achieves the intended purpose of providing a sign that does not require electric power and that has a strong power to shine prominently. In addition, the reflective layer, the colored layer, and the light-shielding layer are more prominent, and are effective for ensuring safety.
