BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a road marking pillar used for a center line, a lane change line, a lane, etc. of a road.

[0002]

2. Description of the Related Art Generally, as a road signpost of this type,
There are a fixed type embedded in the road surface, a road surface standing type, and the like, and as the material of the pillar main body, a hollow molded product of a rubber material or a plastic material is used in addition to a hollow metal pipe. By directly applying fluorescent paint that is reflected by the night illumination light of the vehicle to the outer peripheral surface of the pillar body, or by providing a reflective sign strip that is intermittently attached with a reflective sheet in the vertical direction of the pillar, Some have improved visibility for vehicle drivers and passersby.

By the way, in the case of such a conventional road sign post, a vehicle or the like comes into contact with the reflective sign strip to cause peeling, cracking, and scarring, or dirt due to adhesion of dust deteriorates its visibility at an early stage. There is a phenomenon. Although peeling and cracking may be expensive and labor-intensive, there is a possibility of repairing by installing a new reflective sign strip. But,
Since dirt due to dust contains an oil component, most of the reflective sign strips cannot be regenerated, and even if the dirt is removed and made usable, a great deal of labor and cost are required. As a means for removing dirt, in addition to wiping relying on the work force of the worker, there is a case where cleaning is performed by spraying water with a dedicated self-propelled cleaning machine. In the case of this special cleaning machine, the cleaning brush rotating at a high speed may damage the reflective sign strip, causing peeling or cracking, which may have an adverse effect. Regardless of which cleaning method is used, there are restrictions such as working under traffic restrictions, and it is not possible to carry out frequent traffic restrictions especially in locations with heavy traffic. In addition, it is desired that the work be completed in a short period of time even if it is carried out, and there is a problem that stains may occur early even if it is washed in a place where traffic is heavy or inside a tunnel.

SUMMARY OF THE INVENTION The present invention has been improved in order to eliminate such a problem, and can protect the sign portion from damage due to impact, peeling and cracking during dirt cleaning, and visibility of passing vehicles and passersby. It is an object of the present invention to provide a road signpost that can maintain a suitable road condition at all times.

[0005]

A road sign post according to the present invention comprises a hollow or solid tubular inner pillar body fixed at its base to a pedestal, and the inner pillar body being a transparent hollow tube. It is housed in an outer column body shaped like a ring, and the entire inner column body is colored and molded as a reflective marker portion or a reflective marker portion is provided on the surface.

[0006]

After the road surface is installed, the reflective sign portion of the inner pillar body is illuminated and reflected by the headlight of the vehicle running at night through the transparent outer pillar body, and the reflection can be visually recognized by the driver. Even if it becomes necessary to clean due to the adhesion of dirt, the surface of the outer column body can be cleaned, and the inner column body is protected by the outer column body against the impact of collision or contact, impairing the function of the reflective sign portion. There is no need to simply replace the external pillar body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of a road sign post according to the present invention will be described below with reference to the drawings. FIG. 1 is an assembly view of a part of a road sign post according to an embodiment of the present invention, showing a double cylinder structure including an inner post body 11 and an outer post body 12. In the embodiment, the inner column main body 11 is, for example, a hollow body formed of polyurethane elastomer having a relatively high rigidity against breakage, and can be integrally formed or removed at the base end of the pedestal 13 on the lower road surface in the figure. It is installed. The pedestal 13 has a structure in which a fixing bolt 14 is provided on the bottom surface and is screwed into a threaded base (not shown) installed on the road side to be mounted. Polyurethane elastomer can also be used for the material of the pedestal 13.

Further, as shown in the figure, strip-shaped reflective sign portions 15 made of a reflective sheet or fluorescent paint are provided at intervals on the surface of the inner column main body 11 over substantially the entire length thereof, and the vehicle is running at night. By reflecting the light of the illumination light, it is made visible not only to the driver but also to passers-by. It is also possible to replace the intermittently provided reflective marker portion 15 with a hollow molded article in which the entire inner column main body 11 is colored in a suitable color as the reflective marker portion. A structure in which the entire inner column main body 11 is color-molded and a strip-shaped reflective sign portion 15 made of a reflective sheet or fluorescent paint is intermittently provided on the surface based on this is also possible. Further, as the inner column main body 11, a solid round bar body is used instead of the hollow cylindrical body as in the embodiment.

An outer column body 12 is provided so as to surround the inner column body 11 from the outside. The outer column body 12 is formed of a transparent non-yellowing type polyurethane elastomer into a cylindrical shape, and the lower end portion 16 is integrally formed on the base end of the pedestal 13 or is detachably installed.
Therefore, through the transparent outer pillar body 12, the inner pillar body 1
You can see through 1. The upper end opening of the outer column main body 12 is closed by a cap 17 to prevent rainwater dust from entering the column. Polyurethane elastomer can be used for the material of the cap 17 like the inner column main body 11 and the pedestal 13.

As shown in FIG. 2, the cap 22 for closing the upper end opening of the outer column main body 21 is hollow or hollow so as to also close the upper end opening of the inner column main body 23 formed in a hollow cylindrical shape. It can also be formed from a solid polyurethane elastomer or the like.

Further, as shown in FIG. 3, the upper end opening of the inner column main body 31 is closed by a cap 32 to form a gap 34 between the outer periphery of the upper end of the inner column main body 31 and the inner periphery of the upper end of the outer column main body 33. It is also possible to fit and close the ring-shaped spacer 35, which is also formed of polyurethane elastomer or the like.

The outer column body, which is formed into a transparent hollow cylinder and accommodates the inner column body, preferably has its base end fixed to the pedestal, but one end or both ends thereof are open ends, The open end side may be detachably inserted into the inner column body (when only one end is an open end, the other end is closed in a test tube or the like). Such an external pillar body is formed of an elastic body, preferably a non-yellowing type polyurethane elastomer or the like, and by using the external pillar body of such a material, when the external pillar body is used for a long time as a road sign pillar, It is possible to prevent a decrease in the brightness of the reflective sign portion of the inner column body due to yellowing in advance, and it is possible to easily replace the detachable outer column body when yellowing.

With the above structure, after the road surface is installed, the reflective sign portion of the inner pillar body is illuminated by the headlight of the vehicle running at night through the transparent outer pillar body and reflected, and the reflection is reflected by the driver or passerby. Can be seen.
Also, if a passing vehicle or a pedestrian collides with it or if it collides with it to a certain extent, the transparent outer pillar body will be scratched,
Even if it sometimes breaks, the reflective sign portion of the inner pillar body is protected without impairing the marking function, and only the outer pillar body needs to be replaced.

In addition, when the surface of the outer column main body becomes dirty due to dust due to installation and use, and cleaning is required,
Even if water is sprayed by the above-mentioned washing machine, it is protected by the outer column body, so that the reflection marker portion is not damaged regardless of the inner column body. Efficient watering restores the transparent surface of the outer pillar body.

In the above embodiments, a polyurethane elastomer having a relatively high impact resistance was used for the outer column body, but those which are installed in a place where a collision impact by a vehicle or the like is relatively small are: It is also possible to use a transparent material such as polycarbonate resin or acrylic resin for the outer column main body. When a resin or the like having low impact resistance is used, the entire column including the inner column body can be easily removed from the pedestal and attached.

[0016]

As described above, in the road sign pillar according to the present invention, after the road surface is installed, the reflective sign portion of the inner pillar body is illuminated by the headlight of the vehicle running at night through the transparent outer pillar body. It is reflected and the driver can see this reflection. Even if the outer pillar body needs to be replaced by a shock due to a collision or a contact, the inner pillar body is protected and the function of the reflective sign portion is not impaired. In addition, the cleaning work to remove dirt can be done by targeting the external pillar body,
Since the reflective sign part of the inner column body is protected, there is no worry of peeling or cracking of the sign part as in the case of water spray cleaning with a conventional cleaning brush, it enables efficient cleaning and the function of the sign part is Can always be maintained.
