Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-luminous road tack that is installed at a median strip, a pedestrian strip, an intersection, and other dangerous places of a road, and is particularly suitable for a snowy area.

[0002]

2. Description of the Related Art Conventionally, as a self-luminous road tack, for example, a solar cell in the tack and a storage battery for storing the electromotive force of the solar cell,
A light-emitting body driven by a storage battery, and one containing a controller for controlling light emission of the light-emitting body, the solar cell,
It is known that a commercial power source or a primary battery is used instead of the storage battery, and both are always installed so as to project from the road surface.

[0003]

However, since all of the conventional self-luminous road tacks are installed so as to always project from the road surface for the reasons described below, in a snowy area, they interfere with the snow removal work during the snowy season. Then, it collided with the shovel of the snow removing work vehicle, and both the tack and the shovel were damaged, which hindered road maintenance work.

That is, when a solar cell or a storage battery is used, an amorphous silicon solar cell or a crystalline silicon solar cell having a power generation capacity of several days in a fine day is used as the solar cell, and the lead battery is used. Since a sealed battery that has a charge capacity of several days is used, the size of the light emitting part, control part, and power supply part becomes large and bulky, so that it will not interfere with snow removal work during the snow season. Even if it is intended to be installed under the road so that it can be stored, it requires a large-scale installation work, which makes it difficult to put it into practical use.

Also, when a primary battery is used, since a battery having a large capacity of 100 to 300 Ah is used, the same bulky and large-scale installation work is required as described above, which makes it difficult to put it into practical use. There was a point. In addition, when using a commercial power source, electrical wiring work is required, the installation location is limited, and it is difficult to put the tacks to practical use because the tacks cannot be moved under the road such as storing the tacks in the snowy season. was there.

It is an object of the present invention to provide a self-luminous road tack suitable for a snowy area, which solves the above conventional problems.

[0007]

In order to solve the above-mentioned problems, the present invention uses a compound semiconductor thin film solar cell, a coin type small capacity storage battery or a small capacity primary battery as a power source of a light emitting body to emit light by itself. The rivet body with functions has been made compact so that it can be used only during the snow-free season and can be inverted during the snow-covered season to be easily stored under the road surface.

That is, the self-luminous road tack of the present invention comprises a tack main body and a storage case embedded in the road. The tack main body projects from the road surface and is attached to the storage case, and is turned upside down so that the back surface is almost the road surface. It is designed so that it can be stored and mounted in a storage case so that it is flush with each other, and the compound semiconductor thin-film solar cell in the tack body, a coin-type small-capacity storage battery that stores the electromotive force of the solar cell, and a light-emitting body driven by the storage battery. And a controller for controlling the light emission of the light emitting body.

Further, instead of the above solar cell and storage battery,
A small-capacity primary battery of 5 Ah was used, and the stud body housed the primary battery, a light-emitting body driven by the primary battery, and a controller for controlling the light emission of the light-emitting body, and the primary battery was housed in a replaceable manner. It is a thing.

[0010]

[Function] During the snow-free season, the tack main body projects from the road surface and is attached to the storage case, so that it self-lumines to warn the vehicle driver. As a result, it does not interfere with snow removal work. Further, the self-luminous tack main body can be made compact, and the storage and mounting during the snow season can be facilitated.

Lead batteries, air batteries, nickel-cadmium batteries and the like are preferably used. Further, a chemical cell or a fuel cell which can supply electric power without external energy supply for about 250 days may be used.

The tack main body 1 is made compact by using the solar cell 3, the storage battery 4 or the primary battery 6. As shown in FIG. 4, a back cover 9 is detachably attached or openably and closably attached to the opening of the back surface of the tack body 1 so that each member can be housed in the tack body 1 and the primary battery 6 can be replaced. In addition, a plurality of retroreflectors 10 are generally attached to the side wall of the tack main body 1 to provide an effect of improving night visibility.

A storage case 7 is made of a material similar to that of the tack body 1 and has a container-like shape with an open upper portion capable of housing the tack body 1 and a flange portion protruding from the upper edge. .
The storage case 7 is provided inside with a mounting step portion 11 having a bolt hole corresponding to the mounting portion 8 of the tack body 1, and the tack body 1 is mounted so as to close the upper opening. As shown in FIG. 1, the storage case 7 is buried in the road so that the upper edge flange is substantially flush with the road surface 13.

However, the self-luminous road tack of the present invention is such that the tack main body 1 projects from the road surface 13 as shown in FIGS. And are fixed by bolts 12. Figures 3 and 4 during the snow season
As described above, the tack body 1 is turned upside down and housed in the housing case 7, and the mounting portion 8 and the mounting step portion 11 are fixed by the bolts 12. At this time, the back surface of the tack body 1 is substantially flush with the road surface 13. When the snow-covered season changes to the snow-free season, the primary battery 6 in the tack body 1 is replaced with a new battery.

[0019]

As described above in detail, in the self-luminous road tack of the present invention, the tack main body having a self-luminous function is turned upside down and is housed and mounted in the housing case so that the back surface is substantially flush with the road surface. Therefore, it does not interfere with the snow removal work during the snowy season and does not hinder road maintenance work.
