DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light emitting road stud used for a center line, an outside line, a curb, a curve, a branch point, a junction, a stop line, or a multi-story parking lot of a road. .

[0002]

2. Description of the Related Art Conventional light-emitting road studs having a built-in energized light-emitting body include a stud having a built-in solar battery in each stud body and a stud body and a stud body using a commercially available round or flat wire. There is a method of connecting between them.

[0003] The above-described solar battery does not require electric wires to emit the road studs, so that it is not necessary to embed and lay the electric wires, and the work of installing the road studs on the road is easy. there were. However, when a plurality of studs containing a solar battery are installed on a road, there is a problem that light emission cannot be synchronized with blinking or step blinking cannot be performed.

[0004] Therefore, in order to perform the synchronous blinking, a method of connecting between the studs using an electric wire has been adopted. Here, a stud body of the above-mentioned type installed on a road is shown in FIG. Each stud body of this system connects a flat electric wire protruding from the stud body to an electric wire of another stud body by a connector, and is buried in a road using a burying adhesive after the connection.

[0005] However, the method of connecting each of the above-mentioned studs with an electric wire has a disadvantage that the installation and wiring of the electric wire are troublesome at the time of installation. Specifically, when embedding a stud body connected with an electric wire on a road, a core hole processing for processing a core hole for embedding the stud body and a slit processing for processing a slit for embedding the electric wire are performed in advance. Although it is necessary to apply it to the road, the length between the core holes must be set with a tolerance of about ± 20 mm for the set length between the studs and 1 to 5 m. It was difficult to machine the road surface. If the length between the core holes exceeds the error range, work such as manually shaving the road surface with the actual thing must be performed to match the length between the core holes with the set length between the rivet bodies. In addition, there is an inconvenience that the installation work requires a great deal of trouble.

In order to solve the above problem, Japanese Patent Laid-Open Publication No.
No. 000-303413 has disclosed a light emitting tack for road use. According to this, each stud body is connected by a protection tube which covers the electric wire, and the electric wire passing through the inside of the protection tube is wired by a terminal block inside each stud body. Further, since this stud body is configured to be opened, it can be repaired by removing the stud body and removing the electric wire from the terminal block during maintenance after installation.

[0007]

However, when installing the light emitting stud for roads disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 2000-303413, the length between the core holes and the set length between the studs may have the aforementioned error. If it exceeds the range, it is necessary to perform actual matching on the site and cut the protective tube and the electric wire according to the length between the core holes, so that there is an inconvenience that the installation work on the site is troublesome.

The object of the present invention is to remedy the above disadvantages,
An object of the present invention is to provide a light-emitting road stud that is easy to bury, wire, install, and maintain after installation.
