Description

[Detailed description of the invention] [Field of industrial application] The present invention is applicable to road signs that are arranged in a row on the surface of a paved road to indicate the center line of a roadway, indicate lane guidance, etc., especially for roads in snowy regions. It's about signs.

[Conventional technology]

Three-dimensional road signs that are arranged and installed on paved roads to indicate the center line of the roadway, lane guidance, etc., have traditionally been hollow figurines made of rubber material; A flat figurine or a hollow figurine made of plastic material are known. However, this type of 3D road sign is often collided with or trampled by passing vehicles, resulting in problems such as the base being damaged and the 3D road sign easily coming off the pedestal.

In order to improve these points, the inventor of the present invention integrated a hollow tube made of soft polyurethane with a base made of hard polyurethane, and created a structure that absorbs and disperses the impact when it is hit by a vehicle, making it less likely to be damaged. He invented a hollow three-dimensional road sign that can be quickly restored even if it is deformed by being stepped on, and is currently in the process of implementing it (see Japanese Patent Publication No. 62-56282).

On the other hand, in countries where it snows for a long period of time, 3D road signs that protrude a considerable height from the road surface are inconvenient for snow removal, so while they have a noticeable visibility effect during the non-snowing season, during the snowy season There is a demand for road signs that can avoid any hindrance.

In order to meet the demands of such snowy regions, we have developed road markings and covers for the snowy season that can be fixed and buried in the road surface, and that can be detachably fixed to the buried object separately from the buried object. A road for a snowy region, wherein a road marking body is fixed to the buried body during the non-snowy season, and a cover for the snowy season is fixed in place of the road marking body during the snowy season to cover the buried body. A marker is known (see Utility Model Application Publication No. 59-47713).

[The problem that the idea attempts to solve]

However, the road sign for snowy areas described in Japanese Utility Model Publication No. 59-47713 has the problem that if it is collided with or trampled by a passing vehicle, the three-dimensional road sign may be fundamentally damaged or come off the pedestal. be. On the other hand, the inventor of the present invention previously invented the
In the hollow three-dimensional road sign described in Publication No. 56282,
It cannot be attached or detached for use in areas with snowfall.

In view of the problems of the prior art as described above, the present invention provides a hollow three-dimensional road sign that is resistant to damage even if it is collided with or trampled by a passing vehicle, and that can be quickly restored. To provide a road sign for snowy areas that can be removed during the snowy season and replaced with a cover for the snowy season.

[Means to solve the problem]

In order to achieve the above-mentioned objectives, the present invention has been developed to provide a road marking body that is capable of embedding and fixing a buried body in the road surface, and also a road marking body that can be detachably fixed to the buried body separately from the buried body, and a cover for the snowy season. A road marking body is fixed to the buried body during the non-snowy season, and a covering body for the snowy season is fixed in place of the road marking body during the snowy season, and the buried body is fixed to the covering body for the snowy season. In a road sign for a snowy area, the buried body is constituted by a buried tube having an inner circumferential thread and at least one recessed step on the outer periphery, and the road sign body is covered with: A hollow marker made of soft polyurethane with a horizontal hole in the lower part, a plate-shaped body having upper and lower through holes, and an inner peripheral screw of the buried cylinder formed downward and integrated with the plate-shaped body, compatible with It is composed of a fixing fitting made of a spiral tube, and a hard polyurethane pedestal formed by embedding the lower part of the hollow sign body and the plate-like body of the fixing fitting, and the hollow sign body and the pedestal are combined into a hollow sign. It is characterized in that it is integrated through a horizontal hole in the body, and the fixing fitting and the pedestal are integrated through upper and lower through holes in the plate-like body.

[Effect]

Since the road sign for snowy regions of the present invention has the above-described configuration, the hollow sign body made of soft polyurethane and the pedestal made of hard polyurethane are firmly integrated through the horizontal hole of the hollow sign body, and the pedestal and The fixing metal fittings are firmly integrated through the upper and lower through-holes of the plate-like body of the fixing metal fittings, and thus, during the snowy season, the hollow sign body can be removed from the buried tube together with the fixing metal fittings and replaced with a cover for the snowy season. To obtain a road sign for a snowy area, which is hard to be damaged and can be quickly restored even if it is collided with or trampled by a passing vehicle during a non-snowy season.
