Abstract

(57) [Summary] [Purpose] Effectively preventing not only longitudinal slippage but also skid slippage of a vehicle, so that not only a rear-end collision accident such as a collision accident,
Prevent accidents such as contact accidents caused by protrusions on curved roads. [Structure] On the surface of the road, a large number of projections each having a length of about 6 to 10 cm and a height of about 1 to 2 cm and having a substantially square shape in a plane are arranged in rows and columns at substantially equal intervals on each side of the square. Non-slip on the road.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an anti-skid road for automobiles, and particularly effectively prevents not only vertical skidding but also skid skiing of a vehicle. It is also designed to prevent contact accidents and the like due to protrusions in the department.

[0002]

[Prior art]

 It is already known that a road groove is formed by carving a groove in the width direction of the road, especially on the slope of the road.

[0003]

[Problems to be solved by the device]

 However, although the conventional groove in the width direction as an anti-skid road is effective in preventing vertical slippage of the vehicle, it cannot prevent side slippage of the automobile, and therefore, it cannot be contacted by the protrusion on the curved portion of the road. There is a problem that accidents cannot be prevented. In view of these facts, the present invention was made in order to provide not only a rear-end collision accident but also a road slip prevention that prevents a contact accident caused by a protrusion on a curved portion of a road. is there.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides a substantially square flat protrusion on each surface of a road having a length of about 6 to 10 cm and a height of about 1 to 2 cm. It provides a non-slip road that is lined up in rows and columns at equal intervals.

[0005]

[Action]

 In an anti-skid road according to the present invention, when an automobile brakes, a large amount of friction is generated between the tire of the automobile and the edge of the substantially square protrusion on the plane to prevent the automobile from slipping. It At this time, since a large number of substantially square-shaped protrusions are arranged side by side in the vertical and horizontal directions, not only the vertical slip of the automobile but also the horizontal slip is effectively prevented. Therefore, when the anti-slip structure of the present invention is applied to a curved portion of a road, the vehicle is prevented from protruding due to skidding. In addition, although the size of the automobile tire varies depending on the type of automobile, etc., considering the diameter and width of the tire, the length of each side of the substantially square planar protrusion is about 6 to 10 cm, and the height of the protrusion is About 1 to 2 cm is appropriate. When the length of each side or the height of the protrusion of the substantially square planar shape deviates from these ranges, the effect as the anti-slip means is not sufficiently exerted. If the protrusion height exceeds 2 cm, the tire may be damaged. Furthermore, it is necessary that the projections having a substantially square shape in a plane be arranged side by side at substantially equal intervals on each side of the substantially square. If the spacing between the protrusions is narrower than this, there will be no significant friction between the automobile tire and the edge of the substantially square protrusion in the plane, while if the spacing between the protrusions is too wide, The frequency with which the tire comes into contact with the edge of the substantially square-shaped protrusion on the plane is reduced, and in either case, the anti-slip effect cannot be expected so much.

[0006]

【Example】

 Next, an embodiment of the present invention will be described with reference to the accompanying drawings. The anti-skid road according to the present invention has a substantially square flat projection 1 having a length of about 6 to 10 cm and a height of about 1 to 2 cm on the surface of the road. It is made up of a large number of columns arranged side by side. That is, as shown in FIG. 1, if the length of each side of the projection 1 having a substantially square shape in a plane is a and the distance between the projections 1 is A, then a is approximately 6 to 10 cm, a = A. Further, as shown in FIG. 2, if the height of the protrusion 1 is h, then h = 1 to 2 cm. Reference numeral 2 in FIG. 3 is an automobile tire.

[0007]

[Effect of device]

 As described above, according to the present invention, not only longitudinal slippage of a vehicle but also lateral slippage thereof can be effectively prevented. Therefore, not only a rear-end collision such as a collision accident but also a curved portion of a road can be prevented. It is possible to prevent contact accidents caused by the protrusion.
