DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a road marking body installed on a road surface for use as a lane separation sign such as a center line sign for a road, a lane guidance sign, or the like, or for traffic regulation or danger signage.

[0002]

2. Description of the Related Art Conventionally, this type of road marking body is generally a safety cone or the like in which a vertical cylindrical sign body such as a cone or a column is erected above a pedestal base installed on a road surface. What is called is well known.

[0003]

However, in such a conventional road marking body, since the outer peripheral surface of the sign body is exposed without any protection, the outer peripheral surface is exposed to exhaust gas and dust of a traveling vehicle. Therefore, there is a problem that the effect of the marking by the reflective material or the like provided on the outer peripheral surface of the sign body is easily reduced, and the marking effect cannot be maintained for a long time.

An object of the present invention is to provide a road marking object that solves the conventional problems.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention covers a shrink tube made of synthetic resin on the outer peripheral surface to protect the outer peripheral surface of the sign body so that dirt is hardly adhered to the shrink tube. If the tube becomes dirty, the tube is easily peeled off to further maintain the marking effect.

That is, in the road sign according to the present invention, a vertical cylindrical sign body is erected above a base installed on a road surface, and polyethylene terephthalate is provided on the outer peripheral surface of the sign body.
A shrink tube made of synthetic resin comprising: a shrink tube provided with a peeling portion which can be easily cut off along the length direction of the shrink tube. Alternatively, a plurality of synthetic resin shrink tubes made of polyethylene terephthalate are superimposed and covered on the outer peripheral surface of the sign body,
Each of the shrink tubes is provided with a peeling portion which can be easily cut off along the length direction thereof. Alternatively,
A synthetic resin shrink tube is provided on the outer peripheral surface of the sign body.
A synthetic resin film having excellent stain resistance is formed on the outer surface of the tube.

[0007]

The shrink tube on the outer peripheral surface of the sign body makes it difficult for dirt such as exhaust gas and dust from the traveling vehicle to adhere, and the visual effect of the sign body, that is, the effect of marking the outer peripheral surface, is maintained for a long time. . Also, even if dirt adheres to the outer surface of the shrink tube, the dirt is easily removed by rainfall or cleaning, and the marking effect is maintained.If the shrink tube becomes dirty to the extent that the marking effect cannot be maintained, the peeling part is pulled out of the tube. By cutting, the dirty tube can be easily peeled off.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. In the drawings, A is a road marking body, and a vertical tubular marking body 2 is formed upright above a base 1 such as a pedestal installed on the road surface as shown in FIG. The shape and structure of the road sign A may be the same as those of the conventional one, and the base 1 and the sign main body 2 may be separately manufactured and joined or integrated, or may be integrally manufactured in advance. May be done. In addition, the base 1 is generally bolted to the road surface or attached to the road surface via an appropriate member, but may be simply placed on the road surface.

The sign body 2 is generally made of a synthetic resin such as a rubber material or a soft urethane resin and has flexibility, and is flexibly bent and deformed even when it comes into contact with a vehicle or steps on the vehicle. To be restored. The shape of the sign body 2 is a vertical tube of an appropriate shape such as a conical shape or a column shape as in the related art.

A sign 3 is provided on the outer peripheral surface of the sign body 2. The sign 3 is formed, for example, by sticking a reflective material such as a reflective tape or a reflector as shown in FIG. 1 or by giving letters, symbols, patterns, or the like as appropriate, or the outer peripheral surface of the sign body 2. It may be formed by coloring the whole in red or the like for danger marking.

Reference numeral 4 denotes a synthetic resin shrink tube, which is placed on the outer peripheral surface of the sign body 2 to protect at least the sign 3. The shrink tube 4 may be covered over substantially the entire outer peripheral surface of the sign body 2 as shown in FIG. 1, for example, or may be covered only on the portion where the sign 3 is provided. Further, the shrink tube 4 may be covered by a single layer as shown in FIG. 3 or may be covered by a plurality of layers as shown in FIG.

[0012] Examples of the shrink tube 4, claim
For the inventions described in the items 1 and 2, polyethylene tereph
A transparent resin tube made of tarrate is used.
In the invention described in item 3, a transparent resin tube made of, for example, polyvinyl chloride, polyethylene terephthalate, or the like is preferably used. Generally, the shrink tube 4 having a thickness of 50 to 250 μm and a shrinkage of 20 to 50% is suitably used. The shrink tube 4 is provided with a peeling portion 5 which can be easily cut off along the length direction.

The peeling portion 5 may be provided with, for example, perforated cutouts in parallel along the length direction of the shrink tube 4 as shown in FIG. 2, or a groove along the length direction of the tube 4. What is necessary is just to provide the formed thin part and to form it. That is, the peeling portion 5 may be easily cut off from the tube 4 by pulling its end, and the structure is not limited to the above.

Further, a synthetic resin film having excellent contamination resistance may be formed on the outer surface of the shrink tube 4. In this case, dirt is more difficult to adhere to the shrink tube 4, which is preferable. In this case, a shrink tube 4 having the above-mentioned synthetic resin film formed on the outer surface in advance may be used, or the synthetic resin may be used after the shrink tube 4 having no outer surface is covered on the sign body 2. A coating may be formed.

As the synthetic resin having excellent stain resistance,
For example, tetrafluoroethylene resin, trifluoride ethylene resin,
Fluorine resins such as difluoroethylene vinyl ether resin and vinylidene fluoride resin are preferably used. The synthetic resin having excellent stain resistance is generally formed into a film having a thickness of 20 to 50 μm on the outer surface of the shrink tube 4 by coating or other appropriate method.

In the use of the road marking body of the present invention, if the shrink tube 4 becomes dirty so that the marking effect cannot be maintained, the peeling portion 5 is pulled to cut off the dirty tube 4 from the tube 4. At this time, when the tube 4 is single as shown in FIG. 3, a clean outer peripheral surface of the sign body 2 is exposed and may be reused as it is, or may be covered with a new shrink tube 4 in some cases. When a plurality of tubes 4 are overlapped as shown in FIG. 4, a new tube 4 is exposed and can be reused as it is. In the case of FIG. 4, after the innermost layer tube 4 is peeled off, the same operation as in the case of FIG. 3 may be performed.

[0017]

As described in detail above , the claims according to the present invention are described below.
1 road marking material according the polyether on an outer peripheral surface of the marking body
A synthetic resin shrink tube made of tylene terephthalate is covered, and the shrink tube is provided with a peelable portion that can be easily cut out along its length direction. Even if the shrink tube is not easily adhered and the shrink tube becomes dirty so that the sign effect cannot be maintained, the peeling portion can easily peel the tube, and the sign effect on the outer peripheral surface of the sign body can be maintained for a long time.

The road marking according to claim 2 of the present invention.
示体is the polyethylene terephthalate to the outer peripheral surface of the marking body
Since multiple shrink tubes made of synthetic resin made of tallate are covered in layers, even if the shrink tubes become dirty so that the marking effect cannot be maintained, peeling off these tubes exposes new tubes, and peels off the dirty tubes one after another. The marking effect on the outer peripheral surface of the sign body can be maintained for a longer period of time.

The road according to claim 3 of the present invention.
The sign body is made of synthetic resin shrink
The shrink tube is covered and a synthetic resin film with excellent contamination resistance is formed on the outer surface of the shrink tube. Therefore, dirt such as exhaust gas or dust of a traveling vehicle is less likely to adhere to the outer surface of the shrink tube. The marking effect on the outer peripheral surface of the main body can be maintained for a long time.

Further, since the shrink tube made of synthetic resin is put on the outer peripheral surface of the sign body, an existing antifouling film made of a tube can be easily provided on the existing road sign body to extend the sign effect.
