Description

  The present invention relates to a road marking sheet that is installed on a road surface and displays by road marking, and a mounting structure of the road marking sheet.

Autonomous accidents on the road can be caused by various causes such as overspeed, drowsy driving, drunk driving and so on. Among them, a car accident caused by reverse running that runs in the direction opposite to the driving direction will not only become a serious accident once an accident occurs, but also cause serious damage to those who drive without any fault. is there.
Such reverse running is caused by oversight of road markings or being aware of road markings but not perceived as being unrelated to oneself. Therefore, when considering how to prevent reverse running, it is important to let the driver and passengers (hereinafter referred to as drivers, etc.) recognize road markings more directly.
Here, “road marking” refers to road traffic law and roads indicated by lines, symbols, characters, paint, etc. for the purpose of regulating road traffic and facilitating road traffic according to instructions. It means regulatory markings and instruction markings based on the law.
Looking at the number of car accidents due to reverse running by age group, about half of the drivers are over 65 years old. There is an urgent need to develop road markings that can be easily recognized.
Conventionally, there has been a method of providing a signboard or the like on the side of a road as a way of making a driver recognize a road marking.
However, since such a signboard or the like is provided on the side of the road, there is a problem that a driver or the like needs to keep his eyes away from the traveling direction in order to see the signboard or the like.
In order to solve such a problem, a technique has been developed that allows a driver or the like to recognize a road marking without having to keep his gaze away from the traveling direction.
As such a prior art, for example, there is Patent Document 1 below.

In the present embodiment, the main body sheet 10 is formed of a black rubber sheet having a substantially trapezoidal cross section, as shown in part in FIG.
Here, “substantially trapezoidal” means a concept including a trapezoid and a trapezoidal shape having at least one pair of opposite sides parallel to each other.
The rubber may be composed of either natural rubber or synthetic rubber.
More preferably, it is desirable to use a hard rubber which contains a fiber such as nylon inside. By setting it as such a structure, it is hard to slip and it can be set as the road marking sheet 1 provided with high intensity | strength, durability, and water resistance.
Of course, the color of the rubber-made sheet | seat which comprises the road marking sheet | seat 1 is not restricted to black, It can change suitably. Moreover, the material which forms the road marking sheet 1 is not restricted to a rubber sheet, and may be a resin sheet.
As the resin, for example, a synthetic resin such as plastic can be used.

The display area 11 is an area for displaying by road marking.
In the present embodiment, the display region 11 is formed by performing V-groove processing on the upper surface of a rubber sheet having a trapezoidal cross section and arranging a plurality of inclined surfaces having an angle with respect to the road surface. .
More specifically, as shown in FIGS. 1 and 2, a V-shape composed of an axisymmetric inclined surface over the entire length in the short direction of the display region 11 in the main body sheet 10 made of a rubber sheet. By forming a plurality of parallel grooves, the forward slope 11a is visible only from the forward direction and has an angle with respect to the road surface, and visible only from the reverse direction, and the road surface. A plurality of reverse running inclined surfaces 11b having an angle with respect to each other are alternately arranged in parallel.
Here, “forward running direction” means a direction from bottom to top in FIG. 1, and “reverse running direction” means a direction from top to bottom in FIG. .
