Description

The present invention relates to a road sign post.
The present invention also relates to a road sign post useful for a road shoulder, a road center line, a lane change, a separation zone, and the like.

Furthermore, the present invention relates to a road sign post in which a certain information function is added to the road sign post.
Furthermore, the present invention relates to a road sign pillar that can read certain information by making the color of the pole body different from the color of the retroreflective tape.

Conventionally, a road sign pillar shown in FIG. 5 is known.
This kind of road sign post 400 includes a pedestal 100 fixed to the road surface G, a cylindrical pole body 200 made of an elastic material provided perpendicularly to a central portion on the upper surface side of the pedestal 100, and an outer periphery of the pole body 200. The retroreflective tape 300 is attached to the surface.
The road sign column 400 is installed on the center line of the road, the shoulder (outer line) of the road, etc., and the headlight light from the vehicle at night is reflected to inform the existence of the road sign column 400. It has a function.

However, the function of the road sign post 400 in the daytime is limited to the division function due to the presence of a plurality of road sign posts 400 on the center line of the road, the shoulders (outer lines) of the road, and other information display. There were no functions.
For this reason, in order to convey specific information to the driver, a signboard such as “Steep Curve Danger” is installed near the shoulder of the road, or text or information is displayed on the guard fence post with paint. (Patent Document 2).

However, these display objects are all made of a hard material such as metal or resin. If the vehicle touches or collides with the display object, the vehicle is not only damaged, but the display object is also deformed. This caused a problem that the function could not be performed.
Furthermore, conventionally, a display object must be newly provided separately from the road sign post 400, and there has been a problem that costs increase.

JP 2001-109386 A

  The present invention has been made in view of such problems, and provides a road sign pillar that does not require a display object for newly displaying information by adding an information display function to the road sign pillar. It is to be.

  The road sign pillar of the present invention includes a pedestal 1 fixed to a road surface G, a cylindrical pole body 2 made of an elastic material provided perpendicularly to a central portion on the upper surface side of the pedestal 1, and an outer periphery of the pole body 2 A plurality of road sign pillars 4 having different attachment positions of the retroreflective tape 3 attached to the outer peripheral surface of the pole body 2 in a road sign pillar 4 composed of the retroreflective tape 3 attached to the surface. Thus, certain information can be read.

The present invention has the following effects.
According to the road sign pillar of the first aspect of the invention, it is not necessary to provide a display object for newly displaying information by adding an information display function to the road sign pillar.

Moreover, according to the road sign pillar of the invention described in claim 2, an information display function can be added without impairing the function of the conventional road sign pillar.
Furthermore, according to the road sign pillar of the invention described in claim 3, information can be transmitted more reliably.

Furthermore, according to the road sign pillar of the invention of claim 4, it is particularly effective in the road sign pillar provided on the shoulder before the T-shaped road.
In addition, according to the road sign pillar of the invention described in claim 5, it is particularly effective in the road sign pillar provided on the shoulder of the road before the curve.

Hereinafter, the best mode for carrying out the present invention will be described.
The best mode for carrying out the invention will be described with reference to FIGS.

A first embodiment of the present invention will be described with reference to FIGS.
This kind of road sign pillar 4 includes a pedestal 1 fixed to the road surface G, a cylindrical pole body 2 made of an elastic material provided perpendicularly to a central portion on the upper surface side of the pedestal 1, and an outer periphery of the pole body 2 It is comprised from the retroreflection tape 3 attached to the surface.
As shown in FIG. 1, certain information can be read by combining a plurality of road sign pillars 4 with different attachment positions of the retroreflective tape 3 attached to the outer peripheral surface of the pole body 2.

In other words, a plurality of 15 road sign pillars 4 (some of the road sign pillars 4 do not have the retroreflective tape 3) with different retroreflective tape 3 mounting positions shown in FIG. As shown in FIG. 2, when the object is arranged on the road surface G near the shoulder before the curve, the character information of “curve” can be recognized from the driver.
The color of the pole body 2 is different from the color of the retroreflective tape 3. If the pole body 2 is orange and the color of the retroreflective tape 3 is white, identification is easy and a good information transmission function is achieved. Can be demonstrated.

The color of the pole body 2 and the color of the retroreflective tape 3 are not limited to these colors, and various combinations of colors are possible. For example, the color of the retroreflective tape 3 can be used as a combination of a plurality of different colors.
The pole body 2 and the base 1 are both made of polyurethane material. For this reason,
Even when the vehicle contacts or collides with the pole body 2, the vehicle is not damaged, the pole body 2 is not damaged, and the display function can be maintained.

  Further, as the material of the pole body 2, thermoplastic polyurethane, soft polyolefin, elastomer and the like are appropriately selected and used, and thermoplastic polyurethane is particularly preferable.

Next, a second embodiment of the present invention will be described with reference to FIGS.
That is, a plurality of 15 road sign pillars 4 (some of the road sign pillars 4 do not have the retroreflective tape 3) with different attachment positions of the retroreflective tape 3 shown in FIG. 3 are arranged at equal intervals. As shown in FIG. 4, when the object is placed on the road surface G near the shoulder before the T-shaped road, the character information of “T-shaped” can be recognized from the driver.
In addition to the character information, for example, a symbol or a sign such as “⇒” indicating one-way traffic can be displayed.

  Further, the present invention is not limited to the best mode for carrying out the invention described above, and various other configurations can be adopted without departing from the gist of the present invention.

It is the figure which looked at what arranged the road sign pillar concerning the 1st example of the present invention at equal intervals from the side. It is the figure seen from the driver's eyes in the state which installed the road sign pillar shown in FIG. 1 on the road surface before a curve. It is the figure which looked at what arranged the road sign pillar concerning the 2nd example of the present invention at equal intervals from the side. FIG. 4 is a view of the road sign pillar shown in FIG. 3 as viewed from the driver's perspective in a state where it is installed on the road surface in front of the T-shaped road. It is a front view of the road sign pillar which concerns on a prior art.
