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, a road marking device such as a road stud is provided on a separation zone of a road. Although there are various road marking devices, as described in Japanese Patent Publication No. 61-15203, there are many road marking devices including a sign body and a reflector. The road marking device will be described in more detail. The sign body is formed between a lower surface attached to a road surface, an inclined surface which is inclined so as to become narrower from both sides of the lower surface and an upper surface thereof. An upper surface composed of a top surface provided on the upper surface and a concave portion provided on the inclined surface, the reflecting plate is provided with a glass plate on the surface of the reflecting portion,
The reflection plate is attached to the concave portion of the sign main body by inserting the reflection plate so as to be inclined at a predetermined angle, for example, 30 ° with the glass plate as a surface.

[0003]

However, at a certain angle,
For example, if a reflecting plate is provided so as to be inclined at an angle of 30 °, when a vehicle such as an automobile passes over the road marking device, the tire attached to the wheel has the weight of the vehicle. The glass plate provided on the surface of the reflection plate is damaged due to the deep inside of the concave portion, and the reflection function of the reflection plate is reduced. As a result, there is a problem that the road marking device becomes difficult for a driver of the vehicle to see. . In addition, since the sign body and the reflector are integrally formed, the reflector has insufficient 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 a reflection plate is hardly damaged.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to achieve the above object, and comprises a polycarbonate sign body and a reflector, wherein the sign body has a lower surface attached to a road surface. From the upper surface consisting of an inclined surface which is inclined so as to become narrower from both sides of the lower surface and the top surface provided between the inclined surfaces on both sides, and a concave portion provided on the 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 reflecting plate is provided with the reflecting portion and a gas superposed on the surface.
The lath plate has both ends of the plate piece bent and
The reflector is mounted integrally with a reinforcing frame capable of holding the glass plate, and the reflector is mounted in the recess of the marker body on a substantially vertical surface with a glass plate facing the surface.

[0005] 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 a bolt, may have a number of recesses into which the adhesive enters, or may be a leg so that it can be embedded in the road. May be protruded. The reflector used in the reflector in the present invention may be any one that is easy for the driver of the vehicle to see. In particular, a retroreflective plate that reflects light projected from the vehicle in the projection direction is preferable because it is easy for a driver to see.

[0006]

In the road marking device of the present invention, since the reflector 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 attached to the vehicle enters the concave portion of the road marking device deeply due to the weight of the vehicle, the tire does not reach the reflector attached to the vertical surface.

As described above, since the tire does not reach the reflecting plate, the glass plate on the surface is hard and the reflecting plate has a strength in which the reflecting portion and the glass plate are integrally joined by the reinforcing frame. Together, the reflector is hardly damaged.

Further, in the road marking device of the present invention, since the reflecting plate and the reflecting portion and the glass plate are integrally connected to each other by the reinforcing frame and attached to the concave portion of the marking body, the reflecting body and the reflecting plate are not provided. Can be manufactured separately. Therefore, the sign body and the reflecting plate can be made of suitable materials, respectively, without being restricted by the manufacturing method.

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

1 to 3, reference numeral 1 denotes a road marking device. The road marking device 1 includes a sign body 2 and a reflector 3. The sign body 2 is made of polycarbonate and has a lower surface 4 attached to a road surface, an inclined surface 51 inclined so as to become narrower from both sides of the lower surface 4 and an inclined surface 51 on both sides. The upper surface 5 includes a top surface 52 provided on the inclined surface 51, and the concave portion 6 provided on the inclined surface 51. The concave portion 6 is provided on the inclined surface 51 and is formed by a substantially vertical surface 61 and a substantially horizontal surface 62. In addition, the sign body 2 is usually about 100 to 150 mm in the longitudinal direction, 40 to 100 mm in the transverse direction, and about 10 to 25 mm in height.

The reflecting plate 3 has a glass plate 31 and a reflecting portion 32 made of a retroreflective plate made of an acrylic resin or the like, which are integrally connected by a reinforcing frame 33 made of a metal such as aluminum. As shown in FIG. 3, the reinforcing frame 33 has both ends of the plate piece bent so that the glass plate 31 can be held on the surface of the reflecting portion 32 by being overlapped. The reinforcing frame 33 may be made of a strong resin.

The reflector 3 is attached to a substantially vertical surface 61 of the recess 6 with an adhesive or a screw. As described above, since the reflecting plate 3 is formed by integrally joining the glass plate 31 and the reflecting portion 32 with the reinforcing frame 33, unlike the case where the reflecting plate 3 is integrally formed with the sign main body 2 as in the related art,
Each can be manufactured separately using the optimal material.

Next, a construction method and a usage method of the road marking device 1 will be described. The road marking device 1 is mounted at predetermined intervals on the median strip of the road. In the method of mounting the road marking device 1, an adhesive is applied to the lower surface of the road marking device 1, and the road marking device 1 is pressed against a predetermined position of the median strip and mounted.

The road marking device 1 thus mounted
When the vehicle passes over the vehicle, the tires of the vehicle enter deep into the concave portion 6 of the road marking device 1, but do not reach the reflector 3 attached to the substantially vertical surface 61. As described above, since the tire does not directly reach the reflecting plate 3, the surface of the reflecting plate 3 is hardly damaged due to the hardness of the glass plate 31 provided on the surface of the reflecting plate 3.

[0015]

According to the road marking device of the present invention, since the sign body is made of polycarbonate and the reflecting plate is mounted on a substantially vertical surface forming a concave portion, the vehicle is placed on the road marking device. Even if the vehicle passes, the sign body does not deform due to the weight of the vehicle, the glass plate on the surface of the reflector in the recess is not distorted and damaged, and the tire of the passing vehicle does not reach the glass plate, and the Abrasion does not occur, and reflection performance is not easily impaired. In addition, the reflection plate has strength because the glass plate and the reflection portion are integrally connected by the reinforcing frame, and is hardly damaged.

Further, since the glass plate and the reflection portion of the reflector are integrally connected to each other by a reinforcing frame and attached to the sign body, the sign body and the reflector are separately manufactured using optimum materials. be able to.
