Description

[Detailed Description of the Invention] This invention relates to a road marking body that is attached to the road surface and serves as a traffic sign for pedestrians, cyclists, motorists, etc.

Road markings are used as a means of marking many roads, such as road center lines, roadside strips for pedestrians, designated lanes for buses, bicycles, etc., crosswalks, lane boundaries, and diversion zones. Its basic structure consists of a head that protrudes above the road surface and a part of the anchor that is buried underground.

The function as a road sign is achieved by the protrusion of the head from the road surface or by the difference in color from the road surface, but if the road sign body is formed in a single color, it can be easily distinguished from the road surface. However, it had the disadvantage that its functions were not fully utilized.

On the other hand, in conventional road markings of this type, both the head and part of the anchor are made of strong metal, with the assumption that a car will ride on them. When the area is wet from rain, pedestrians and cyclists may slip and fall due to the road markings, or they may suffer unexpected injuries from the road markings. Ta.

In addition, some conventional road markings have been designed to prevent slipping by providing unevenness on the head surface, but such devices also have tires with a large ground contact area and are not heavy. Even if it is effective against some automobiles, it is not so effective against pedestrians, bicycles, etc., which have a small ground contact area and are lightweight, and has not been able to prevent unexpected accidents such as those mentioned above.

In view of this point of view, this invention provides road markings for pedestrians and/or cyclists such as pedestrian lanes, bicycle lanes, crosswalks, etc., and prevents these people from falling over due to road markings. To provide a road marking used in places where there is a risk of slipping, and which absorbs the shock of falling and prevents serious injury even if the road marking falls and hits the road marking. It is something to do.

Hereinafter, this invention will be described in detail based on embodiments shown in the accompanying drawings.

The road marking body 1 according to the first embodiment of this invention shown in FIGS. 1 and 2 is made of metal, concrete, hard synthetic resin, or other material having strength and rigidity and is formed into a substantially rectangular truncated pyramid shape. a head 2 that protrudes above the road surface when attached to the road surface; an anchor part 3 that is provided on the lower surface of the head 2 and is buried underground when attached to the road surface; The shock absorber 4 is provided so as to cover the entire surface of the head 2 and is made of resin or rubber and has elasticity.

This buffer body 4 is made by laminating a first layer 10a and a second layer 10b made of soft synthetic resins of different colors. The first layer 10a fixed to the head 2 is attached to the surface of the road marking body 1 by fitting the mounting protrusion 6 and gluing between the head 2 and the first layer 10a with a suitable adhesive. It is formed so as to be partially exposed to the second layer 10b forming the second layer 10b.

Next, the road marking body 1 of the second embodiment shown in FIG. 3 is different from the case of the first embodiment described above, and is formed in a band shape on the upper surface of the head 2, and has a first layer 10a and a second layer 10b. The road marking body 1 of the third embodiment shown in FIG.
The head 2 is formed into a flat plate shape, and an edge 7 is formed around its periphery, and a roughly rectangular truncated pyramid-shaped buffer 4 is fitted into the edge 7 on the upper surface of the head 2, and is bonded etc. It was fixed by the following means.

In the road marking body 1 of the second embodiment, the number of shock absorbers 4 to be attached can be reduced to the necessary minimum, reducing manufacturing costs, and in the road marking body 1 of the third embodiment, By increasing the wall thickness of the buffer body 4, the shock absorption performance can be further improved.

As mentioned above, in the road marking body 1 of the present invention, the head part 2 is covered with the buffer body 4 consisting of the first layer 10a and the second layer 10b, so that the surface part is color-coded.
It has a buffering effect that absorbs the shock when falling, but in order to further exhibit the buffering effect of the buffer 4,
It is possible to take various structures.

FIG. 5 shows a case where the cushioning effect is increased by forming a hollow part 8 in the first layer 10a.In addition, the first layer 10a is formed of a foam etc. By forming the second layer 10b with resin or rubber (
FIG. 6), the buffering effect can be increased.

Furthermore, as shown in FIG. 7, if a skin layer 9 made of hard synthetic resin or the like containing a fluorescent agent is provided on the surface of the second layer 10b, it can function as a sign even at night. Can be done.

Therefore, according to the road sign of this invention, since an elastic buffer is provided on the surface of the head that projects upward from the road surface, this road sign can be used to create roadside zones for pedestrians and bicycles. If road markings are placed in areas where pedestrians and bicycles pass, such as traffic lanes and crosswalks, the buffer provided on the surface of the head of a pedestrian or bicycle will be reduced when a pedestrian or bicycle steps on or rides over a road marking. This increases the contact area between pedestrians' feet and cyclists' wheels, which makes it difficult for relatively lightweight pedestrians and bicycles to slip, and even if a pedestrian or bicycle falls and protrudes onto the road surface. Even if it hits a road marking, the shock absorber absorbs the impact and does not form a large hole.

In addition, according to the road marking of this invention, there is little risk of a vehicle running over it, but if it is used in a place where it is completely unthinkable, the structure of the buffer body is shown in Figures 4 to 6. The structure shown in Figure 1 is designed to improve shock absorption and cushioning properties, and conversely, when used for marking crosswalks, etc., there is a risk that vehicles will frequently run over or run over it. The materials to be used at the locations can be appropriately selected and used, such as by minimizing the use of buffers, as shown in FIG.

The buffer body 4 is composed of a first layer 10a and a second layer 10b made of soft synthetic resin, and the first layer 10a is partially exposed to the second layer 10b. Therefore, the surface part is color-coded, and the road marking body 1 serving as a road marking can be made to stand out well regardless of day or night.

In each of the above embodiments, the size is such that a car or bicycle can normally ride on it, that is, the height protruding above the road surface is relatively small. The present invention can also be applied to road markings of a size that cannot be used, that is, the height that projects above the road surface is relatively large, and in such cases, it can be used as a substitute for a road curb or , can be used for boundaries between roadways and sidewalks, etc.

In addition, the head and part of the anchor are made of hard synthetic resin, and when the head and part of the anchor are molded, a cushioning body made of soft synthetic resin is integrally molded on the head surface, thereby creating a road marking object. It can also be made entirely of synthetic resin and used as a road marking body for use in places where vehicles cannot run over it.
