As a plural number of bent gutter type metals 4 are integrally moulded and given proper rigidity, even by collision of an automobile, a road-sign structural body A is not detached.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention temporarily fixes a vehicle on a road surface in order to divide a lane of an automobile road, regulate a traveling area, and guide a vehicle to a specific zone. It relates to a road sign structure that can be set up.

[0002]

2. Description of the Related Art As a road sign, there is known a road sign comprising a cylindrical body made of rubber or a synthetic resin material and a sign installation board at its lower end (see Japanese Utility Model Laid-Open No. 120512/1989). In this road sign, as the above cylindrical body, a reinforcing cloth is integrally provided along the inner wall surface thereof,
Further, a brim-shaped locking portion is provided at the lower end. And, the above-mentioned sign installation board is composed of a sign installation board capable of closing the lower end of the cylindrical body and a holding ring that can be fitted to the outside of the sign installation board, and of the cylindrical body inserted from below into the holding ring. The brim-shaped locking portion is locked by the locking portion on the inner wall of the pressing ring, and the sign installation board is fitted to the pressing ring so as to close the lower end of the cylindrical body, and is interposed between the pressing ring and the base body. This is a structure in which the brim-shaped locking portion at the lower end of the cylindrical body is tightly held.

[0003]

By the way, in the above-mentioned conventional road signs, since a reinforcing cloth is provided inside the inner wall surface of the cylindrical body made of rubber or synthetic resin to reinforce the cylindrical body, cracks are not generated. Even if it can be reduced, there is a problem that the restoring force when it is pushed by the tire of a traveling automobile is not sufficient and the durability when it is repeatedly stepped down by the tire is poor. Also, since the cylindrical body, the sign installation board and the pressing ring are made of the same material, when the above sign installation board is fixed to the road surface with bolts and used semi-permanently,
It was difficult to attach and detach the pressing ring and the cylinder to and from the sign board. Moreover, when such a road sign is repaired and replaced, it is often done while the vehicle is running, and this replacement work requires a short and simple work procedure. The construction of the road sign requires a considerable amount of time to install the road sign structure. On the other hand, when an automobile collides with the road structure at a high speed, there is a drawback in that a portion of the lower end of the cylindrical body which is integrally formed with the sign installation board is detached from the sign installation board.

[0004]

As a result of earnest research for solving the above-mentioned problems, the present invention has been achieved, that is, the present invention holds a cylindrical body and a lower end portion of the cylindrical body in a detachable manner. What is claimed is: 1. A road sign structure comprising a sign installation board for erecting a cylindrical body on a road surface, wherein the cylindrical body is integrally formed of a soft elastomer and has a cylindrical opening at a lower end and a gutter-shaped flange around the lower end of the cylindrical portion.
