A lateral groove 23 for attaching the reflecting member 3 is formed on the outer peripheral side surface of the base 2 over the entire circumference.
The reflecting member 3 is attached by being wound around the side groove portion 23 of the base 2, thereby making it difficult for the reflecting member 3 to be detached from the base 2, and without causing the reflector 31 to protrude so far from the outer surface of the base 2. It can be provided, and it is preferable because it can prevent displacement in the vertical direction. Further, the reflection member 3 may be attached to the outer periphery of the base 2 without providing the side groove portion 23. In addition, the reflecting member 3 may be attached with a reflecting tape as it is, or may be attached so that a glass reflector is embedded in the outer periphery of the base 2 as it is.

The base 2 of this embodiment has a circular annular groove 24 formed on the upper surface thereof. The annular groove 24 is formed concentrically with the base 2.
The lower end of the main body column 10 is inserted into the annular groove 22 and is fixed by being fused to the base 2.
The fixing method of the main body column 10 to the base 2 is not limited to fusion, and may be selected or combined by bonding with an adhesive, fixing with screws, rivets, or the like. Further, the main body column 10 may be formed integrally with the base 2 when the base 2 is formed, instead of being formed separately from the base 2.

A cylindrical inner pillar 25 protruding upward is provided on the upper surface of the base 2.
The inner column 25 is provided concentrically inside the annular groove 21, and a gap is formed between the inner surface of the main body column 10 fixed to the annular groove 21 and the outer surface of the inner column 25. To be arranged.

  The inner pillar 25 is flexible so that it bends elastically when a vehicle or the like comes into contact with it, and then restores the original state. Thus, by providing the inner pillar 25 having flexibility so as to be arranged inside the main body pillar 10, when the main body pillar 10 is bent near the root due to contact with a vehicle or the like, The restoring force of the inner pillar 25 is added to the restoring force, the restoring force of the main body pillar 10 is increased, and the main body pillar 10 can be more reliably returned to the original state.

The inner pillar 25 is formed integrally with the base 2 when the base 2 is formed by injection molding. The base 2 of the present embodiment is formed of a material such that the inner pillar 25 has flexibility, and specifically, is formed of urethane resin.
The material of the base 2 is not limited to urethane resin, but synthetic rubber such as natural rubber, butadiene styrene rubber, neoprene, butadiene acrylonitrile rubber, chloroprene polymer, butyl rubber, polyurethane resin, polyisobutylene resin, ethylene vinyl acetate. A synthetic resin such as a copolymer, a silicone resin, an olefin-based or urethane-based elastomer may be selected or combined.
The inner pillar 25 is integrally formed when the base 2 is molded. However, the present invention is not limited to this, and the inner pillar 25 is formed in a cylindrical shape separate from the base 2 for bonding or melting. The inner pillar 25 may be fixed to the base 2 by selecting or combining attachment, fixing by screws, rivets, or the like.

The marker column 1 of the present embodiment has a metal color coating applied to the outer surface thereof to form a coating film 5 of the metal color coating.
The coating film 5 of the metal color coating is formed on the entire outer surface of the marker column 1 except for each reflection sheet S, the reflection member 3 and the male screw portion of the anchor bolt portion 21, and is applied to the main column 10 or cap to be applied. 11 and the base 2 are formed in a metallic appearance.
The coating film 5 of the metallic color coating has higher conductivity than the main body column 10, the cap 11 and the base 2 to be applied, and is provided so as to function as an antistatic layer.
Thus, by making the coating film 5 of the metal color coating an antistatic layer, the charging of the marker column 1 due to static electricity is suppressed, and the adhesion of dirt such as fine sand and dust to the surface of the marker column 1 is reduced. Yes.

The coating film 5 of the metal color coating of the present embodiment increases the conductivity of the coating film by containing a conductive substance in the coating material.
The paint for forming the metal-colored coating film 5 of the present embodiment uses a two-component curable transparent ink that is formed into a coating film by mixing a curing agent, but is not limited thereto. Those having high adhesion to the application surface and capable of following the deformation of the main body column 10 can be selected or combined. For example, you may use oil-based letterpress ink, flexographic ink, dry offset ink, gravure ink, gravure offset ink, pad ink, offset ink, etc., but use screen ink with the above-mentioned excellent characteristics suitably Can do. As the ink, a transparent so-called medium in which a vehicle and various auxiliary agents are added to the base resin can be suitably used, and a thermosetting type, a photocuring type such as an ultraviolet ray or an infrared ray, an electron beam curable type, etc. However, it is preferable to use an evaporative drying type solvent that can form the metal-colored coating film 5 without deforming the synthetic resin or the like used for forming the marker column 1.
Moreover, you may use coating materials other than ink.

The metal-colored coating film 5 of the present embodiment contains aluminum powder, and contains metal powder composed of about 20 to 30 parts by weight of aluminum powder with respect to 100 parts by weight of the solid component of the paint.
Due to the inclusion of the metal powder, the coated surface on which the metal-colored coating film 5 is applied is provided so as to be visually recognized as a metallic appearance. However, the present invention is not limited to this, and another configuration in which the surface to be coated is provided in a metallic style may be used. For example, metal powder other than aluminum powder may be mixed, or a method other than mixing metal powder may be used.

Further, the metal-colored coating film 5 is enhanced in conductivity by the contained metal powder and functions as an antistatic layer.
The method for increasing the conductivity of the metal-colored coating film 5 is not limited to the inclusion of the metal powder, and other substances that increase the conductivity of the coating film may be used. For example, powders or fibers of inorganic materials such as metals other than aluminum and carbon, and organic materials such as polyaniline, polyacetylene, polypyrrole, and polythiophene may be selected or combined to adjust the content. Good.

The marker column 1 of the present embodiment is visually recognized as a metal-like appearance as a whole by the metallic color coating film 5 applied to the entire outer surface.
For this reason, it can be expected that the driver of the vehicle who visually observes the installed sign post 1 mistakenly recognizes that the sign post 1 is made of metal and does not damage the vehicle by touching the sign post 1 to make it more proactive. Contamination and damage of the sign post 1 due to vehicle contact can be suppressed.
The coating film 5 of the metal color coating of this embodiment makes the marker pillar 1 visually recognizable by making the transparent paint contain the metal powder. By containing 20 parts by weight or more of the metal powder with respect to 100 parts by weight of the solid component of the transparent paint, the surface to be coated with the metal-colored coating film 5 is well concealed by the metal powder, Since it can provide so that it may be visually recognized more metallicly, it is preferable. Further, since the flexibility of the coating film 5 is reduced when the content of the metal powder is too large, in order to form the coating film 5 of the metal color coating so as to be able to follow the elastic deformation of the main body column 10, The metal powder is preferably contained in an amount of 80 parts by weight or less based on 100 parts by weight of the solid component of the paint.

In addition, the main body column 10 of the present embodiment having flexibility has a restoring force that can be restored within 2 seconds when restoring from the bent state to the original state by receiving an external force.
If the main body pillar 10 that is visually recognized as metallic is formed as described above, even if the main body pillar 10 is bent due to contact with a vehicle, the main body pillar 10 is restored within 2 seconds to be like a metal pillar body. Since it returns to the state visually recognized, it is preferable because the driver of the following vehicle is difficult to visually recognize the bent state of the main body column 10 and the main body column 10 is easily misidentified as a metal column.
Further, even when the driver of the following vehicle visually observes the state in which the main body column 10 is bent due to contact with the vehicle, the state in which the main body column 10 that appears to be made of metal is bent is straightened within 2 seconds. Since it is visually recognized so as to be restored vigorously, it is preferable because it makes the driver feel a sense of incongruity and can more actively avoid contact of the driving vehicle with the sign post.
In addition, restoring to the original state of “restoring from a bent state by receiving external force” described above means returning to a state in which the main body column 10 can be seen as if standing upright. However, it does not return to a position that is not different from the main body pillar 10 in a state before being bent. That is, when the state of the main body column 10 before being bent is compared with the state of the main body column 10 restored after being bent, a slight difference may occur in the inclination or the like.

FIG. 5 is a cross-sectional view of the vicinity of the base 2 showing an outline of the formed metallic color coating film 5.
Before attaching each reflecting sheet S and the reflecting member 3, the marking pillar 1 of the present embodiment applies a metal color coating to the entire outer surface of the cap 11, the main body pillar 10, and the base 2 to form a coating film. After that, each reflection sheet S and the reflection member 3 are attached and provided.
That is, the metallic color coating film 5 is formed as a continuous coating film on the surface of the marker column 1.
In addition, the male screw of the anchor bolt portion 21 protruding from the base 2 is subjected to masking or the like in advance so that it is not difficult to screw with the anchor nut N by the coated paint film 5 of the metal color coating. However, it is provided so that the end of the coating 5 of the metal color coating is in contact with the upper end of the male screw of the protruding anchor bolt portion 21.

  The marker column 1 of the present embodiment has the metal-colored coating film 5 formed as a continuous coating film on the lower end of the outer peripheral side surface of the base 2, that is, the outer edge of the lower surface of the base 2 in contact with the installation surface G. It is formed to reach. Thereby, the static electricity of the main body column 10 can be efficiently released to the installation surface G through the metal color coating film 5 functioning as an antistatic layer, and the contamination of the marker column 1 due to static electricity can be effectively suppressed.

  Further, the marker column 1 of the present embodiment is formed by contacting the metal-colored coating film 5 formed as a continuous coating film with the upper end of the anchor bolt part 21 to be screwed to the anchor nut N. The static electricity of the main body pillar 10 can be efficiently released under the installation surface G via the anchor bolt part 21 and the anchor nut N through the metal color coating film 5 that functions as an antistatic layer. Contamination of the pillar 1 can be effectively suppressed.

In order to suppress electrification of the main body column 10 of the marker column 1 due to static electricity, a conductive substance can be included in the material of the main body column 10, but in order to obtain a sufficient antistatic effect, a conductive substance is used. Need a lot. Further, in the case of a marker column having a structure in which the main body column 10 and the base 2 are formed separately and then integrally attached, a highly conductive antistatic portion is continuously arranged from the main body column 10 to the base 2. It is difficult.
Since the marker pillar 1 of this embodiment forms the coating film 5 of the metal color coating that functions as an antistatic layer by painting on the outer surface thereof, the main pillar 10 formed separately and integrally attached It is possible to easily form a continuous coating 5 of a metal color coating on the outer surface with the base 2.

  In addition, the marker pillar 1 which concerns on this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the summary of this invention.

For example, in the marker pillar 1 of the present embodiment, the reflection sheet S is attached to the outer surface of the main body pillar 10, but it may not be attached.
Moreover, although the reflecting member 3 is attached to the base 2, it does not need to be attached.
