DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete plate for identifying a pavement surface such as a platform.

[0002]

2. Description of the Related Art Hitherto, a light-emitting display body in which a display body is formed of a light-emitting synthetic resin and a light-emitting element is embedded in the display body has been developed (Japanese Patent Application No. 4-67647, previously filed on Heisei). March 25, 4th, Japanese Patent Application Laid-Open No. 5-321213 (Application for claiming domestic priority on April 4, 1992).

In the case of a luminescent synthetic resin, the synthetic resin itself has a luminescent property, such as a mixture of a transparent synthetic resin and a fluorescent or luminescent paint, and the luminescent property is enhanced by an embedded light emitting element. .

In the daytime, it is not necessary to use an expensive luminescent synthetic resin mixed with an expensive fluorescent or luminescent paint or the like for a concrete plate for identifying a pavement surface, and it is meaningless to mix a fluorescent or luminescent paint or the like.

[0005] In addition, although the yellow paint is generally applied to the concrete plate for identifying the pavement surface, there is a problem that the coating of the spherical projection is easily peeled off.

[0006]

SUMMARY OF THE INVENTION According to the present invention, it is possible to easily identify a spherical projection on a concrete plate for identifying a pavement surface, and to provide a clear concrete plate for identifying a pavement surface without requiring painting on the projection. The purpose is to gain.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention adjusts the number of transparent small balls, mixes the small balls into a light-transmitting synthetic resin, and mixes the small balls into a concrete plate. A buried cylindrical inner luminous upper surface opening frame is filled, a light source by a light emitting diode is provided in the filling portion, and the upper surface of the opening frame is opened to the upper surface of a concrete plate. Protruding into a spherical shape, a translucent synthetic tree
A light source insertion hole is formed in the center of the fat, and the upper end surface of the insertion hole is
It is made of a concrete plate for identifying a pavement surface which is shielded from light and provided with a vertical slide adjustment device for a light source .

[0008]

According to the present invention, the upper surface of the concrete plate is laid so as to match the upper surface of the pavement surface, and a concrete line for identifying blind or semi-blind persons or a dangerous line of a platform of a station can be constructed.

A light emitting diode is inserted into the light source insertion hole, the vertical position of the light emitting diode is adjusted, and an electric current is conducted to the light emitting diode to emit light from the diode or the light source. Spreads in four directions and diagonally upward. Then, the light is reflected and diffused on the outer surface of the small sphere in the translucent synthetic resin and the inner surface of the opening frame. The projections or spherical projections shine and the presence of these projections is aroused by human vision.

The brightness of the surface of the protruding portion is adjusted by adjusting the ratio of the light-transmitting synthetic resin to the small balls and the level of the light emitting diode of the light source, and the colors of the light emitting diode or the light source are red, yellow, and blue. And the diameter of the top opening cylinder can be adjusted relatively large.

[0011]

EXAMPLE A plurality of transparent hollow glass spheres (beads) or solid glass spheres 1 are mixed with a heated thermoplastic translucent synthetic resin, and the mixture is mixed with a cylindrical inner luminous top opening having an inner diameter of 36 mmφ. A frame 4 (made of an aluminum frame or an inner mirror surface metal) is filled, an insertion hole 8 for a light source 5 formed by a light emitting diode (LED) 5 ′ is formed at the center, and the synthetic resin 2 is inserted through the upper opening of the opening frame 4. Are protruded to cool and harden. The cylindrical upper surface opening frame 4 is made to protrude upward in a spherical shape 6 to be cooled and hardened. The light source 5 may be a miniature bulb. The translucency means not only colorless and transparent but also translucent, colored and transparent.

The upper surface of the upper opening frame 4 coincides with the upper surface of the rectangular concrete plate 3 and is buried in the concrete plate 3 (FIG. 1). The color 5 'may be red when the upper surface of the concrete plate 3 is yellow, but may be other colors. The upper end of a screw rod 9 is connected to the light source 5 and screwed into a female screw hole 10 provided at the lower end entrance of the insertion hole 8.
A nut 11 is screwed onto the screw rod 9 on the outer side of the screw hole 9 to form a vertical slide adjustment device 12 for the light source 5, and a light-shielding portion 13 is formed at the upper end of the insertion hole 8 by an arc-shaped light-shielding plate bulging upward. .

Further, the greater the number of the glass spheres 1, the greater the amount of reflected light, and by increasing the inner diameter of the cylindrical opening frame 4 to about 36 mmφ, the luminosity of the luminous surface of the spherical projection 6 'can be increased. .

[0014]

According to the present invention, as described above, the diameter of the bright portion on the concrete plate for identifying a pavement surface can be increased.
Since it is inconspicuous from a distance, it is possible to clarify the identification line such as walking or platform regardless of day or night, thereby improving safety.

Further, the brightness is adjusted by adjusting the level of the light source, and the brightness of the bright portion can be averaged without the risk that the light is concentrated on the central portion due to the light shielding surface.
