[Conventional technology]

Conventionally, as this type of road marking body, for example, Japanese Patent Publication No. 62-56282 discloses The hollow statue road signs described above are known. This hollow statue road sign is The center part of the pedestal made of casting type hard polyurethane has a cap on the top end. A soft polyurethane tube to which the tube is fixed is installed vertically, and this is placed inside the root of the tube. A short polyurethane tube that is shorter and smaller in diameter than the tube is installed vertically on the pedestal. .

[Problem that the idea aims to solve]

However, such conventional ones are made of soft polyurethane with a cap on the top end. is attached by post-processing and cast into the lower end of the pipe with a short pipe fitted inside the lower end. Since a pedestal is formed and the above-mentioned pipes and short pipes are planted perpendicularly to the pedestal, manufacturing is time-consuming. There are some problems that make it difficult to mass produce. Also, during molding, both tubes and short tubes are cast. Because the pedestal material is separated, the adhesion between the pipe or short pipe and the pedestal may not necessarily be sufficient. However, if the tube is stepped on repeatedly by a vehicle, there is a risk that the tube, short tube, and pedestal may come off.

0004 The purpose of this invention is to provide a road marking that eliminates such conventional problems. are doing.

[0005]

[Means to solve the problem]

The road markings of this invention are vertically hollow cylinders that are integrally molded from synthetic resin. The cylindrical body has an air vent hole at the top end and an external hole at the bottom end. A pedestal part with a peripheral surface bulging outward is provided, and a tooth-shaped unevenness is provided on the inner peripheral surface of the lower end in the circumferential direction. The base is provided with a short cylindrical reinforcement part on the base, and a tooth-shaped reinforcement part on the outer peripheral surface of the base. The unevenness is provided in the circumferential direction, and the reinforcing part of the base is inserted into the lower end of the cylindrical body to form the base. The lower end surface of the cylindrical body is closed, and when the tooth-shaped irregularities are fitted together, Both are glued together.

[0006]

【Example】

The present invention will be described below with reference to the drawings. In the drawing, 1 is a cylindrical body, which is injected with synthetic resin such as urethane resin. Molded. The cylindrical body 1 has an elastic shape such as a conical shape or a cylindrical shape. It is a vertically elongated hollow body. As shown in FIG. 1, an air vent hole 11 is provided at the upper end of the cylindrical body 1. is opened, and a pedestal part 12 whose outer peripheral surface bulges outward is provided at the lower end. . The air vent hole 11 is used to vent air inside the cylindrical body 1 when the cylindrical body 1 is stepped on by a vehicle. This serves to prevent damage. The upper surface of the pedestal section 12 is arranged from the center toward the periphery. The sloped surface is designed to reduce the impact even if stepped on by a vehicle. Ru.

[0007] Tooth-shaped unevenness 13 is provided in the circumferential direction on the inner circumferential surface of the lower end portion of the cylindrical body 1 . The tooth-shaped unevenness 13 is generally provided on the inner peripheral surface of the cylindrical body 1 corresponding to the pedestal portion 12. ing. In the case of FIG. 3, the tooth-shaped unevenness 13 divides the inner circumferential surface of the cylindrical body 1 into three equal parts. A large recess is provided, and small irregularities are arranged between the recesses. . Incidentally, the tooth-shaped unevenness 13 may have uniform unevenness throughout.

[0008] The outer surface of the cylindrical body 1 may be decorated with letters, symbols, patterns, etc. as appropriate. A reflective material 14 may be attached as shown in FIG. Reference numeral 2 denotes a base body, which is injection molded from synthetic resin such as urethane resin. base As shown in FIG. 1, the body 2 has a short cylindrical reinforcing portion 22 protruding from a base 21. Base 21 has a shape that matches the lower end opening of the cylindrical body 1, and has the above-mentioned teeth on the outer peripheral surface as shown in FIG. A tooth-shaped unevenness 23 that fits with the shaped unevenness 13 is provided. The reinforcing part 22 is a cylindrical main body. It has a short cylindrical shape with a smaller diameter than the inner diameter of the body 1, and is installed almost vertically on the base 21. It is used to reinforce the lower end of the shaped main body 1.

[0009] Therefore, in the road marking body of the present invention, the base body 2 is reinforced within the lower end opening of the cylindrical body 1. The portion 22 is inserted and the base 21 closes the opening. or, The tooth-shaped unevenness 13, 23 of the cylindrical body 1 and the base 21 are fitted together and bonded with adhesive. Integrated adhesive. When installing the road marking of this invention on the road, use anchor bolts or adhesive. The base 21 of the base body 2 and the pedestal portion 12 of the cylindrical body 1 may be fixed to the road surface. In addition, As shown in Fig. 1, the anchor bolt 3 is embedded in the base 21 of the base body 2 in advance and is If you make it protrude and integrate it with the anchor nut 4 embedded in the road surface, Easy to install and preferred.

[Effect of the idea]

As detailed above, the road markings of the present invention are integrally molded from synthetic resin. It consists of a cylindrical body and a base, both of which are glued together, reducing manufacturing time. It is easy to mass-produce without requiring much time. In addition, the tooth-shaped unevenness provided on the inner circumferential surface of the lower end of the cylindrical body and the outer circumferential surface of the base of the base body. The provided tooth-shaped irregularities are fitted together and integrated with adhesive, so that a cylindrical shape is formed. By increasing the adhesive area between the main body and the base, the two can be firmly bonded, and can be stepped on repeatedly by a vehicle. It is difficult to separate the cylindrical body and the base even if
