Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to variable road markings for snowy regions that can be used in different ways depending on the snowy season and non-snowy season.

[Background of the invention]

In countries where the snowfall season is long, road studs that protrude a considerable height above the road surface are inconvenient for snow removal, so they are buried flush with the road surface during the snowfall season.
Road studs that are raised from the road surface during non-snowy seasons have been proposed (Utility Model Publication No. 4159, 1983;
(See No. 165015, etc.)

However, with the road studs mentioned above, the marking lines such as the center line, lane boundary line, and outside line of the road are not useful during the snowy season, so the marking lines are painted directly on the road surface. On roads with heavy traffic, each lot line has been scraped away by spiked tires or anti-skid chains, and most of the lines have been erased after the snowy season, and each lot line must be repaired in the spring. Must be. In particular, the fact that the center line of the roadway has been erased is a serious matter for traffic managers, and the cost of repair work is enormous.

[Purpose of the invention]

The present invention improves the problems of the conventional technology in snowy regions as described above, and is installed as a raised road sign with excellent visibility during non-snowy seasons, and quickly changes to a road surface sign that does not interfere with snow removal during the snowy season. The purpose is to provide road markings that can be used for road markings.

[Summary of the invention]

In order to achieve the above objects, the present invention has the following features:
A fixed leg installed buried in the road surface, a road surface marking body for the snowy season that does not interfere with snowfall attached to the fixed leg, and a road surface marking body for the snowy season that covers the road surface marking body and is attached to the fixed leg. It consists of a removably attached raised road marking for non-snowing seasons, which provides more prominent visibility during non-snowing seasons, and a raised road marking for non-snowing seasons during snowing seasons. It is characterized in that the body is removed and a road surface marking body for the snowy season appears on the road surface.

[Embodiments of the invention]

The attached drawings show an embodiment of the present invention, and FIG. 1 is a longitudinal cross-sectional view showing the installation state in a non-snowing season, FIG. 2 is a plan view, and FIG. 3 is a longitudinal cross-sectional view showing the installation state in the snowy season. The top view and FIG. 4 are also plan views.

As shown in these drawings, the road sign of the present invention has fixed legs 1 installed buried in a paved road A.
, a road marking body 2 for the snowing season that does not interfere with snow removal, which is attached to the fixed leg, and a non-snowing road marking body 2 that is detachably attached to the fixed leg 1 and covering the road marking body for the snowing season. A temporary raised road marking body 3 and a fixing bolt 4 for fixing the road marking body 3 to the fixed leg 1
It consists of:

The fixed leg 1 is made of metal or light metal, and has a stopper step 1a formed at its lower end, a screw hole 1b into which the bolt 4 is screwed, and a screw hole 1b above which is used for the snowy season. A large diameter screw hole 1c is formed into which the leg of the road marking body is screwed. Then, the fixed legs are installed by drilling holes in the paved road, embedding them in the road surface, and filling them with adhesive.

The road marking body 2 for the snowy season is made of synthetic resin, synthetic resin mixed with glass beads, or light metal, and includes a leg part 2a having a screw that is screwed into the fixed leg, and a marking part 2b that covers the road surface. Therefore, the marker portion 2b has a circular shape as shown in the figure, and the height at the center is relatively low.
In addition, it is constructed so that it becomes thinner toward the outer periphery so as to coincide with the road surface A at the outer periphery so as not to interfere with snow removal. Of course, the road surface marking body 2 for the snowy season used in the present invention is not limited to the shapes described above and shown in the drawings, and may be any shape as long as it does not interfere with snow removal. In addition, a square hole 2c is provided in the center of the road marking body 2 for the snowy season, and a bolt 4 inserted into the square hole 2c is attached to the road marking body 2 for the non-snowing season.
can be detachably fixed to the fixed leg 1, and the road surface marking body 2 for the snowy season can be attached to and detached from the fixed leg 1 using this square hole. Note that this road marking for the snowfall season may be made of metal such as stainless steel in areas where the snowfall season is relatively short.

The raised road marking body 3 for the non-snowy season is made of synthetic resin or light metal, has a size and height that can cover the entire surface of the road marking body 2 for the snowy season, and has a height at the center of its lower surface. A recess 3a that fits with the sign part 2b of the snowy season road marking body is formed in the recess 3a, and a bolt insertion hole 3b reaching the recess 3a from the top surface of the recess 3a and a recess 3c into which the head of the bolt 4 is inserted.
form. In addition, a retroreflector 5 such as a cat's-eye retroreflector lens, a light emitting diode, or a prism-type retroreflector plate is attached or formed on the raised road marking body 3 for the non-snow season as desired.

In addition, 6 in the figure is the square hole 2 of the road surface marking body 2 for the snowy season.
c) and is formed, for example, from cork.

The variable road sign for snowy regions of the present invention has the above-mentioned configuration, and is installed and used in the following manner.

First, a hole for embedding the fixed leg is drilled in the road surface, and an adhesive or the like is filled in the hole to bury the fixed leg 1.

Next, screw the leg part 2a of the snow season sign body 2 into the large-diameter screw hole 1c of the leg part 1, and use a tool that fits the square hole 2c as necessary to ensure that the bottom surface of the sign part 2b is flush with the road surface. Screw it in until it is firmly attached.

Next, the raised marking body 3 for the non-snowing season is attached to the concave 3
A fits over the sign part 2b of the sign body 2 for snowy season and installs it on the road surface, screws the bolt 4 into the screw hole 1b of the fixed leg 1 through the square hole 2c, and attaches a spring washer etc. as necessary. The raised sign body 3 for the non-snow season is interposed therebetween and is firmly fixed to the fixed leg 1, and its bottom surface is brought into close contact with the road surface A.

When carrying out the above construction, the following shall be carried out as necessary.

(1) Apply Syobond's elastane to the bottom of the snowy season road marking 2 or the non-snowy season road marking 3, and apply Syobond's 303A to the corresponding paved surface and dry both surfaces. let

(2) Apply waterproof double-sided adhesive tape to the coated surface of the sign 2 or 3 so that when the sign 2 or 3 is installed as described above, the paved surface and the sign will be bonded together. do.

The road sign of the present invention constructed as described above exhibits a remarkable visual recognition effect similar to that of ordinary road studs due to the sign body 3 raised above the road surface when there is no snowfall.

Then, during the snowy season, the bolts 4 are loosened and the non-snowy season markings 3 are removed, and the square holes 2c are filled with a filler 6 such as cork, so that the snowy season road markings 2 are exposed on the road surface. The sign changes quickly. In this state, the snow season road marking 2 has a shape and height that does not interfere with snow removal, so there is no problem with snow removal, and even if the marking part 2b is scratched by spiked tires etc. Since they do not disappear completely, they serve as road markings. Further, if the sign portion 2b is scratched by a spiked tire or the like, it is extremely easy to replace it after the snowfall season has passed.

〔Effect of the invention〕

As described above, the variable road surface sign for snowy regions of the present invention exhibits the same remarkable visibility effect as ordinary road studs except during the snowy season, does not interfere with snow removal during the snowy season, and disappears. It is extremely useful as a road sign for snowy areas because it quickly changes into a road sign that never changes.
