Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a road marking device.

[0002]

2. Description of the Related Art Conventionally, road marking devices such as road tacks have been provided in a road separation zone. There are various road marking devices, but as described in Japanese Patent Publication No. 61-15203, many road marking devices include a sign body and a reflector. This road surface marking device will be described in more detail. The sign body is composed of a lower surface attached to the road surface, an inclined surface inclined so as to become narrower from both sides of the lower surface, and an inclined surface on both sides thereof. The upper surface consisting of the top surface provided in the, and the concave portion provided in this inclined surface, the reflection plate is provided with a glass plate on the surface of the reflection portion, the road surface marking device,
The reflection plate is attached to the concave portion of the sign main body with the glass plate as the surface so as to be inclined at a constant angle, for example, 30 °.

[0003]

However, a certain angle,
For example, if a reflector is provided so as to be inclined at 30 °, when a vehicle such as an automobile passes over the road marking device, the tires attached to the wheels are affected by the weight of the vehicle. Since it goes deep into the recess, the glass plate provided on the surface of the reflection plate is damaged, the reflection function of the reflection plate deteriorates, and as a result, the road marking device becomes difficult for the driver of the vehicle to see. . Also, since the sign body and the reflector are integrally molded, the reflector lacks strength,
There is a problem that the reflector is easily damaged. Therefore, an object of the present invention is to provide a road marking device in which the reflector is hard to be damaged.

[0004]

The present invention has been made to achieve the above object, and comprises a sign body and a reflector, the sign body being a bottom surface attached to a road surface, and An upper surface composed of an inclined surface that is inclined so as to become narrower as it goes upward from both sides of the lower surface and a top surface provided between the inclined surfaces on both sides, and a concave portion provided on this inclined surface, The concave portion is formed by a substantially vertical surface and a substantially horizontal surface provided on the inclined surface of the sign body, and the reflection plate is formed by superimposing a glass plate on the surface of the reflection part and integrally joined by a reinforcing frame body. The reflecting plate is mounted in the concave portion of the sign main body with a glass plate as a surface on a substantially vertical surface thereof.

The lower surface of the sign body in the present invention may have any shape as long as it is attached to the road surface. For example,
It may be a flat surface so that it can be attached to the road surface with an adhesive or bolts, there may be a large number of recesses into which the adhesive enters, and legs that can be embedded in the road. May be projected. Further, the reflecting portion used in the reflecting plate of the present invention may be one that can be easily seen by the driver of the vehicle. In particular, a retroreflection plate that reflects the light projected from the vehicle in the projection direction is preferable because it is easy for the driver to see.

[0006]

In the road marking device of the present invention, since the reflecting plate is provided on the substantially vertical surface forming the recess, the vehicle passes over the road marking device after the road marking device is mounted on the road surface. However, even if the tire mounted on the vehicle enters the recess of the road marking device deeply due to the weight of the vehicle, the tire does not reach the reflection plate mounted on the vertical surface.

Since the tire does not reach the reflection plate as described above, the glass plate on the surface is hard and the reflection plate and the reflection plate and the glass plate are integrally joined by the reinforcing frame to have strength. Together, the reflector is hard to scratch.

Further, in the road marking device of the present invention, the reflecting plate and the reflecting plate and the glass plate are integrally coupled by the reinforcing frame and attached to the concave portion of the marking body. Can be manufactured separately. Therefore, the sign body and the reflector can be made of suitable materials without being restricted by the manufacturing method.

EXAMPLES Next, examples of the present invention will be described. 1 to 3 show an embodiment of the present invention, (a) of FIG. 1 is a plan view of a road marking device, (b) is a front view of the road marking device,
2 is an enlarged sectional view taken along the line AA of FIG. 1, and FIG. 3 is a sectional view of the reflector.

1 to 3, reference numeral 1 denotes a road surface marking device, and the road surface marking device 1 comprises a sign body 2 and a reflector plate 3. The sign body 2 is made of polycarbonate, and is between the lower surface 4 attached to the road surface, the inclined surface 51 that is inclined so as to become narrower from both sides of the lower surface 4 and the inclined surfaces 51 on both sides thereof. An upper surface 5 formed of a top surface 52 provided on the upper surface and a concave portion 6 formed on the inclined surface 51. The recess 6 is provided on the inclined surface 51, and is formed by a substantially vertical surface 61 and a substantially horizontal surface 62. The size of the marker body 2 is usually 100 to 150 mm in the longitudinal direction, 40 to 100 mm in the lateral direction, and 10 to 25 mm in height.

The reflecting plate 3 is formed by integrally bonding a glass plate 31 and a reflecting portion 32 made of a retro-reflecting plate made of acrylic resin or the like with a reinforcing frame 33 made of metal such as aluminum. The reinforcing frame 33 is, for example, as shown in FIG.
Both ends of the plate piece are bent so that the glass plate 3 is formed on the surface of the reflecting portion 32.
It is designed so that one can be overlaid and held. The reinforcing frame 33 may be made of strong resin.

The reflector 3 is attached to the substantially vertical surface 61 of the recess 6 with an adhesive or screws. In this way, since the glass plate 31 and the reflecting portion 32 of the reflector plate 3 are integrally joined by the reinforcing frame body 33, unlike the conventional case where the reflector plate 3 and the sign body 2 are integrally manufactured,
Each can be manufactured separately using the optimum material.

Next, a method of constructing and using the road marking device 1 will be described. The road marking device 1 is attached at predetermined intervals in the median strip of the road. As a method of attaching the road marking device 1, an adhesive is applied to the lower surface of the road marking device 1 and pressed onto a predetermined position of the median strip to be attached.

The road marking device 1 attached in this way
When the vehicle passes over the above, the tire of the vehicle goes deep into the recess 6 of the road marking device 1, but does not reach the reflection plate 3 attached to the substantially vertical surface 61. Since the tire does not reach the reflection plate 3 directly as described above, the surface of the reflection plate 3 is less likely to be damaged in combination with the fact that the glass plate 31 provided on the surface of the reflection plate 3 is hard.

[0015]

In the road marking device of the present invention, since the reflecting plate is attached to the substantially vertical surface forming the recess, even if the vehicle passes over the road marking device, it is not easily damaged. Moreover, since the reflection plate has the glass plate and the reflection portion integrally connected by the reinforcing frame, the reflection plate has strength and is not easily damaged.

Further, in this reflector, the glass plate and the reflector are integrally joined by the reinforcing frame and attached to the sign main body, so that the sign main body and the reflector are separately manufactured from the optimum materials. be able to.
