BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a road sign which is temporarily fixed on a road surface to separate lanes on a motorway, particularly a highway, and to regulate a driving area. More specifically, the present invention relates to a road sign body and a sign mounting member in which a sign mounting member such as a small sign body is further fitted to the tip of a road sign body.

[0002]

2. Description of the Related Art As a road sign, a road sign composed of a hollow cylindrical body made of rubber or synthetic resin and a base portion at the lower end thereof is known (Japanese Utility Model Laid-Open No. 1-120).
No. 512). There is also a road sign and a sign cylinder (Japanese Utility Model Application No. 3-100284) according to the application of the applicant.

[0003] In general, these road signs have a beautiful appearance in view of their intended use, and are clearly recognized by the visual acuity of all drivers day and night, even from the standpoint of their sign functions. It must be.

[0004]

By the way, in order to make the recognition of the presence of the road sign more clear and clear, most of the above-mentioned conventional road signs have one or more stripes on the outer peripheral side of the upper part of the sign body. The light reflection sheet was stuck and wound in the shape.

[0005] However, these light reflecting sheets turn dark black due to contamination from chemical substances such as in soot gas of automobiles, SOX and NOX, or road dust.
In particular, at present, the function of the sign cannot be sufficiently exerted due to contamination of the light reflecting sheet itself, which is the purpose of the sign. In addition, in the conventional sign, since the light reflecting sheet is stuck only on the outer peripheral side, a driver at a high position of a driver's cab such as a hill or a truck having many sharp curves can receive light on the outer surface of the sign. The presence of the reflective sheet is easily overlooked, which causes a problem that the gaze guidance function, which is the original purpose of the road sign, becomes difficult.

The present invention has been made in order to cope with the above-mentioned situation, and in addition to a conventional marker, a marker attaching member capable of detaching various markers is added. In particular, even under these adverse conditions, the driver can be surely and clearly recognized by the driver, and can easily and quickly remove and replace the sign when the sign is unnecessary or renewal, and the sign is provided. It is an object to provide a member.

[0007]

In order to achieve the above-mentioned object, the feature of the present invention is that a small sign is inserted into and detached from an upper part of a road sign main body, and the road sign is hollow cylindrical. A road sign main body comprising a body and a base portion for holding the lower end of the cylindrical body and erecting the cylindrical body on the road surface; and a through-hole at the tip of the hollow cylindrical body of the road sign main body. provided, and the lower end portion of the label attachment member Hamada' freely formed by inserting configure for mounting the label to the through hole
It is in the point which did. Moreover, labeled attachment member mounted for Hamada' to the road marker body top also a feature, the lower <br/> end the member is a hollow cylindrical shape, a 且 one its tip tapered taper portion has been formed, on the outside of the upper the tapered portion is in the configuration in which the insertion slit portion corresponding to the wall thickness of the hollow cylindrical member of a road marker body.

[0008] A part of the road sign body constituting the present invention is constituted by a hollow cylindrical body, and the hollow cylindrical body may be a soft body, and is preferably a natural rubber, a synthetic rubber or the like, particularly preferably a urethane elastomer. Further, the base portion constituting the main body is for erecting the hollow columnar body on the road surface, and may have a portion of somewhat soft rubber or synthetic resin, and includes a base portion previously fixed to the road surface with a bolt or the like. However, the present invention is not limited to this. Therefore, the base portion may be any portion for erecting the cylindrical body on the road surface, and various methods and structures are included.

Further, the sign mounting member for mounting the sign which constitutes the present invention is required to be lightweight, strong, and in particular to have impact resistance, but natural rubber, synthetic rubber, or the like, which is the same or similar to the hollow cylinder described above. Particularly, a urethane elastomer is preferable. And a particularly preferable urethane elastomer is a soft urethane elastomer, which can be easily inserted and detached when the sign attaching member is inserted into the road sign main body, and is not easily detached even by external pressure such as wind pressure. In addition, since a strength that does not cause breakage by a vehicle collision is required, a specific range of the hardness of the soft urethane elastomer is selected from the correlation between the two. That is, the hardness of the hollow cylinder constituting the main body of the road sign is JISA hardness (JIS
K6301) is preferably 65 to 88 degrees, and the hardness of one sign mounting member is also preferably 65 to 88 degrees. It is necessary to form a hollow portion at the lower end portion, and this hollow portion may be penetrated to the upper portion as necessary. The external shape of the sign mounting member may be cylindrical or prismatic, and is appropriately selected depending on the type and shape of the sign to be mounted.

In the present invention, the small marker is a marker that can be attached to a road marker so that the marker can be attached and formed so as to be detachable. The sign attached to the outer surface of the sign attachment member is generally a light reflection sheet, but also includes a miniature bulb, a fluorescent coloring plate, and the like. Replacement or replacement of these markers when their functions are degraded, or removal when they are no longer required, are all performed in a short time as simple manual operations. Alternatively, a sign attaching member to which a sign is pasted may be prepared in advance, and this may be inserted into the tip of the road sign body. Further, it is also preferable that the sign and the sign attaching member are integrally formed, that is, formed as a kind of a small sign. For example, a fluorescent coloring material is poured into a resin material constituting the sign attaching member, and the sign attaching member is integrally formed. It can be formed by molding or other methods.

[0011]

According to the road sign of the present invention constructed as described above, the visual range of the driver can be significantly increased as compared with the case where the road sign is attached to only the main body. That is, since the height of the main body alone is low, a driver at a high position of a driver's cab, such as a truck, often overlooks the sign body, and the same applies to a slope having many sharp curves.

However, in the sign body of the present invention, the sign object can be attached to the side surface of the upper end portion of the entire sign body, and further to the upper surface, so that a driver on a high cab can be surely and clearly observed.

In addition, since the lower end of the marker mounting member which forms a part of the small marker inserted into the upper end of the marker has a hollow shape and a tapered portion which is tapered, the marker mounting member is inserted. At the time of attachment, the contraction and expansion act freely, so that it is easy to insert. Also, since a slit portion corresponding to the thickness of the hollow cylindrical body of the road sign body is provided, a fitted state is formed, and the road sign does not separate due to wind pressure or the like.

Therefore, the sign attaching member can be freely attached and detached from the sign body in a short time so that it can be freely attached to and detached from the sign body, the sign can be renewed and changed freely, and the handling thereof is simple. Since both the main body and the mounting member are made of the same lightweight elastic body, there is no impact damage caused by collision with the car, and of course there is no danger that the car may be damaged due to it, and it is safe for all drivers In addition, the road sign can be visually recognized with certainty.
