JPH093842A - Mark line on road face by slant rib - Google Patents

Abstract

PURPOSE: To increase traffic safety, by providing protruded slant ribs to give appropriate shocks to vehicles on a mark line of a road face. CONSTITUTION: Slant ribs 2 protruding on a mark line 1 of a road face are shaped to form a nearly trapezoidal section and a nearly rectangular plan and further, a flat face at the top. And the front and rear faces against the longitudinal direction of the slant rib mark line 1 in the peripheral faces of the slant ribs 2 are shaped to form tapered faces 2a, 2b with a required angle. And the diagonal angle α against the slant rib mark line 1 is optionally decided within about 5-89 decrees and besides, the length of long and short sides of the slant ribs 2, the height thereof, the angles of curved faces 2a, 2b, and the distance between the slant ribs 2, are also optional.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to intersections, pedestrian crossings, center lines, outside lines, warning lines and symbols, marking lines such as arrows, and slant rib road marking lines to be applied before a railroad crossing.

[0002]

2. Description of the Related Art In a conventional road marking line, for example, as disclosed in Japanese Patent Laid-Open No. 3-262810, on the surface of the road marking line, a diagonal line is formed with respect to the working direction (longitudinal direction). 3m height by shifting the position so that
A circular or elliptical rib having a size of about m to 10 mm formed with a required number of ribs at predetermined intervals, or Japanese Patent Laid-Open Publication No.
As disclosed in Japanese Patent Publication No. 286005, in a road marking line enforced in the center of a road, the required height and required distance are shifted so as to form an oblique pattern with respect to the longitudinal direction (the enforcement direction) thereof. It is known that rod-shaped ribs having a length are formed with a required number and a required interval.

[0003]

However, the above-mentioned Japanese Patent Laid-Open Nos. 3-262810 and 3-286005.
The road marking lines and the road marking lines disclosed in the publication are circular or elliptical or rod-shaped ribs formed in a broken line shape in a plan view, and therefore each rib in each diagonal section Become independent discontinuous states,
As a result, not only there is a problem that a large impact is given to the vehicle and a large noise is generated, but also the light reflection area of each rib in the traveling direction of the vehicle is small, and a large reflection effect cannot be obtained. was there.

[0004]

DISCLOSURE OF THE INVENTION The present invention is intended to solve the above-mentioned problems, and includes intersections, crosswalks, and central lines,
Outer lines, warning lines and symbols, marking lines such as arrows, and slant rib road marking lines that are implemented in front of railroad crossings, etc., with a substantially trapezoidal sectional shape and a substantially rectangular planar shape on the road marking line. It is characterized in that a required number of slant ribs are provided so as to project at a required angle and a spacing with respect to the longitudinal direction of the road marking line.

Further, the slant rib is characterized in that at least the front and rear surfaces of the peripheral surface with respect to the longitudinal direction of the road marking line are formed into a tapered surface or a curved surface having a required angle, and the top is formed into a flat surface. .

[0006]

The slant rib as described above is formed on the road marking line so that the slant rib does not give an appropriate impact to the vehicle to prevent the driver from falling asleep while the vehicle passes. Therefore, it is possible to suppress the noise when the vehicle is passing, reduce the light reflection area at the same time, and improve the light reflection effect.

EXAMPLES Hereinafter, each example of the slant rib road marking line of the present invention will be described in detail, but the present invention is not limited to this example and is applied to the characters, symbols, etc. marked on the road surface. It is also possible to change the design so as to slightly change the embodiment.

FIG. 1 is a perspective view showing a part of a first embodiment of a slant rib road marking line according to the present invention, and FIG. 2 is a--a in FIG.
3 is a partially enlarged sectional view taken along the line, FIG. 3 is a perspective view showing a part of a slant rib road marking line in which the directions of the ribs are reversed, and FIG. 4 is a part of a second embodiment of the slant rib road marking line of the present invention. FIG. 5 is a partially enlarged sectional view taken along the line a′-a ′ in FIG. 4, and FIG. 6 is a perspective view showing a part of the slant rib road marking line with the rib direction reversed.

1 to 6, reference numeral 1 denotes a slant rib road marking line, which is a conventionally well-known paint (including beads). Reference numeral 2 denotes a slant rib, which has a substantially trapezoidal cross-sectional shape and a substantially rectangular planar shape as shown in the drawings, and at least the long side of the slant rib road marking line 1 on the peripheral surface of the slant rib 2. As shown in FIGS. 2 and 4, the front and rear surfaces with respect to the direction are formed as tapered surfaces or curved surfaces 2a and 2b having a required angle, and the top is formed as a flat surface 2c.

The slanted ribs 2 have slant angles α and β with respect to the slant rib road marking line 1 within a range of approximately 5 ° to 89 °, and the slant ribs 2 have long sides,
The length dimension on the short side, the height dimension, the angle of the tapered surfaces or curved surfaces 2a and 2b, the area of the flat surface 2c, and the spacing between the slant ribs 2 are also arbitrary. In the case of FIGS. 1 to 3, the slant rib road marking line 1 has a width of about 200.
The slant angles α and β of each slant rib 2 are about 45 °, and the length dimension on the long side of each slant rib is about 1 mm.
The length of the short side is set to about 08 mm, and the length of the short side is set to about 50 mm, but the length is not limited to this. 4 to 6 show a case where the slant rib 2 has a single shape.

[0011]

According to the slant rib road marking line of the present invention, intersection lines, pedestrian crossings and center lines, outer lines, warning lines and symbols, marking lines such as arrows, slant rib road marking lines to be applied before a railroad crossing, etc. In, on the road marking line, the cross-sectional shape is substantially trapezoidal, and the planar shape is a substantially rectangular slant rib is provided a required number and a predetermined angle with respect to the longitudinal direction of the road marking line, the convex, Since the slant rib is one in which at least front and rear surfaces of the peripheral surface with respect to the longitudinal direction of the road marking line are formed into a tapered surface or a curved surface with a required angle, and the top is formed into a flat surface, the slant rib itself when the vehicle passes through. Effect of taper or curved surface formed on the front and back surfaces and the flat surface on the top surface This prevents the slant rib itself from being damaged, prevents the driver from falling asleep while giving a proper impact to the vehicle, and suppresses the noise when the vehicle passes by, while at the same time increasing the light reflection area. hand,
There are various effects such as high brightness reflection.
