Abstract

(57) [Abstract] [Purpose] To provide an embedded marking device that is not easily damaged by impact. An embedded marking device having a self-luminous marking part, which is used as a traffic sign, wherein the marking part is covered with elastic bodies (1a, 1b, 1c, 2). .

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a self-luminous sign device embedded in a road and used as a traffic safety sign.

[0002]

[Prior art]

 The marking device 10 of this type is formed in a substantially flat plate shape as shown in FIGS. 4 (a) and 4 (b), for example. That is, a rectangular frame 11 made of aluminum alloy or polycarbonate is filled with a filling material 12 such as an epoxy resin, and a light emitting window 13 for a mark is formed in the filling material to embed a light emitting body such as an LED. Then, as shown in FIG. 3B, the connection cable 14 is connected to the outside.

The marking device 10 thus configured is installed on a road or the like as shown in FIGS. 5 (a) and 5 (b). That is, as shown in FIG. 2 (a), it is embedded in an embedding hole 20 provided on a road or the like and is bonded, or as shown in FIG. 2 (b), an anchor bolt 15 is further inserted in the fixing hole 16 and bonded. Fix with agent.

[0004]

[Problems to be solved by the device]

 Since the marking device 10 is installed on a road or the like, it is often damaged or detached from the installation location due to the impact of a passing vehicle. In consideration of this, a hard material that is hard to break and a structure that does not come off easily are adopted, but it is not perfect.

If the object is damaged, scatters and collides against something, the object of collision is damaged.

The present invention has been made in view of the above points, and an object of the present invention is to provide an embedded marking device that is not easily damaged by impact.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides an embedded marking device having a self-luminous marking part, which is used as a traffic sign, wherein the marking part is covered with an elastic body. , Is provided.

[0008]

[Action]

 Since the marking part is covered with an elastic body, it is always applied to the elastic body without being directly impacted. Then, if the elastic body absorbs most of the impact, it only transmits a slight impact to the marking portion. Therefore, it is very unlikely that the marking part will be damaged by the impact.

[0009]

[Effect of device]

 As described above, in the present invention, since the sign portion is covered with the elastic body, the impact is not directly applied to the sign portion, and most of the impact is absorbed by the elastic body, and the sign portion is effectively damaged. Can be prevented. And, even if it is damaged and collides with something, the object to be collided is hardly damaged. Further, since the elastic body can be cut into a desired size and shape without using a frame unlike conventional ones, the structure can be simplified.

【Example】

 1 (a) and 1 (b) are a plan view and a side view showing the external shape of an embodiment of the present invention. In the same figure (a) showing a plane, a square colored urethane resin sheet 1 is provided with a matrix-shaped hole, a light emitting element 3 is arranged in this hole, and a lid 2 is made of transparent urethane resin to provide a marking device. Is configured.

As shown in FIG. 1B, the side surface of this marking device has a structure in which the upper surface is the marking surface and the connection cord 4 is provided on the bottom surface.

FIG. 2 shows a vertical sectional structure around the light emitting element in the marking device of FIG. That is, on the circuit board 1a made of colored urethane, LEDs as the light emitting elements 3 are arranged in a matrix so as to be suitable for displaying a traffic sign, and the light emitting element 3 is surrounded by the intermediate layer 1b made of colored urethane. A panel 1c is provided on the surrounding and further above. In this panel 1c, windows 2 made of transparent urethane are provided in a matrix at positions directly above the light emitting elements 3.

With this configuration, the exposed portion of the marking device is made of urethane resin, and is hardly damaged even when a load is applied or a shock is applied. Even if it is damaged, the urethane resin itself is flexible, so even if it collides with something, it is unlikely to damage the object.

When a frictional force is applied, the frictional force is worn to some extent each time, but if a wear margin is taken to some extent, it can be used for a sufficient period.

FIG. 3 shows a processing method for manufacturing the embodiment shown in FIG. First, a mold 5 for molding the marking device is prepared, and a panel 1c made of colored urethane and a light emitting element 3 provided with a window 2 made of transparent urethane in this order from the elements drawn at the top of the drawing. After stacking the substrates 1a attached with, the urethane resin is poured into the mold 5.

As a result, the colored urethane resin is filled around the light emitting element 3, and the panel 1c and the substrate 1a are integrally molded. It is also a feature of the present invention that the main part of the marking device can be manufactured by such a simple process.
