DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a road marking body which is installed on a road and is movable.

[0002]

2. Description of the Related Art Conventionally, a movable road sign such as a barricade, a construction light, a cone or the like is provided in order to notify a danger area under construction at a work site such as a road construction and to prevent vehicles from entering the area. Reflector sheets that were installed on roads or printed as they were being constructed were directly adhered to the road surface.

[0003]

However, road markings such as the above-mentioned barricades, construction lights, cones and the like are movable, so that they can be easily transported even when they are moved to a work site, and are easily installed. However, it is easy to fall down due to wind pressure, and it is bulky, requiring storage space when not in use.In addition, there is a risk that vehicles etc. may collide with the road signage, and the road signage may be damaged by impact due to collision. There was a problem such as doing.

[0004] Further, in the case of a road marking body in which a reflection sheet is directly adhered to a road surface, it is necessary to attach the reflection sheet to the road surface using an adhesive or the like. Removing the reflective sheet was also troublesome. Further, since the reflection sheet is attached in parallel with the road surface, the sign printed on the reflection sheet from the traveling vehicle is difficult to see and the visibility is poor.

Accordingly, the present invention solves the above-mentioned problems of the conventional road marking body, has no risk of damage by a vehicle or the like, has excellent visibility , and is safe for a vehicle or the like. It will not provide road markings.

[0006]

Means for Solving the Problems In order to achieve the above object, the present invention has the following configuration. That is, in the road marking body according to the present invention, at least one upper surface of the substrate made of an elastic material such as rubber or synthetic resin is inclined with respect to the bottom surface.
It is an inclined surface where the angle rises in the range of 5 degrees to 10 degrees ,
It is characterized in that a retroreflector is attached on the inclined surface with a rigid plate-like body interposed.

[0007]

According to the road sign of the present invention, at least one upper surface of the substrate rises at an inclination angle of 5 to 10 degrees with respect to the bottom surface.
Since the retroreflector is attached to the inclined surface, the reflected light of the retroreflector is easy to see from a traveling vehicle and has excellent visibility. Also, the slope angle of the slope

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be specifically described below with reference to the drawings. Note that the present invention is not limited to these examples.

FIG. 1 is a partially sectional perspective view showing an embodiment of a road marking according to the present invention, and FIG. 2 is a perspective view showing another embodiment of a road marking according to the present invention.

1 and 2, reference numeral 1 denotes a substrate made of an elastic material such as rubber or synthetic resin. At least one upper surface of the substrate 1 has an inclined surface 1 with respect to a bottom surface 12 grounded to a road surface.
1 has been set. The type of the elastic material forming the substrate 1 is not particularly limited as long as it is a material having elasticity. In general, synthetic rubber, urethane resin, silicone resin, ethylene-vinyl acetate copolymer resin and the like are preferably used. Further, it is more preferable to form a fine space inside by using the foamed resin, since the impact from a vehicle or the like is effectively absorbed.

The substrate 1 has at least one upper surface having a bottom surface 1
2 is not particularly limited as long as it is inclined surface 11 with respect to substrate 2. Substrate 1 having a rectangular shape in plan view and a substantially triangular cross section in FIGS. Although the bottom side is the bottom surface 12 and the hypotenuse is the inclined surface 11, the cross section of the substrate 1 may be substantially trapezoidal and one or two of the hypotenuses may be the inclined surface 11,
Other shapes may be used. The inside of the substrate 1 may be hollow or solid, and is not particularly limited.

Regarding the inclination angle of the inclined surface 11 with respect to the bottom surface 12 , the greater the inclination angle, the more the visibility from a vehicle or the like.
Although it is improved, sudden
The impact is dangerous, and the smaller the inclination angle, the more the car
It is safe because sudden impact is not applied to both sides, but it is visible
Sex is reduced. Therefore , in consideration of the visibility from the vehicle and the impact applied to the vehicle and the like riding on it , the present invention
The Ru rising in the range of 5 to 10 degrees with respect to the bottom surface 12
It is safe to tilt without any sudden impact on the vehicle etc. even if the vehicle rides on it without losing visibility
Have been made with horns.

Reference numeral 2 denotes a retroreflector. The retroreflector 2 is mounted on the inclined surface 11 of the substrate 1 with a rigid plate 3 interposed therebetween. In order to attach the retroreflector 2 on the inclined surface 11 of the substrate 1, the plate 3 is attached to the back of the retroreflector 2 with an adhesive or an adhesive beforehand. The plate-like body 3 may be attached to the inclined surface 11 of the substrate 1 in the same manner with an adhesive or an adhesive, or conversely, the plate-like body 3 may be attached to the inclined surface 11 of the substrate 1 in advance. Thereafter, the retroreflector 2 may be attached to the plate-like body 3.

The retro-reflector 2 is a retroreflector for reflecting light incident from a headlight of a vehicle or the like. A sheet-like substrate having flexibility so as not to occur is preferable, for example, a reflection sheet in which glass beads are embedded on the surface of a suitably colored flexible sheet,
A reflection sheet obtained by finely cutting a flexible transparent sheet with a fine diamond is preferably used. The surface of the retroreflector 2 is appropriately provided with an indication 21 such as “under construction”.

The rigid plate 3 has a rigidity such as a metal such as steel, aluminum, copper or zinc, or an alloy thereof, or a synthetic resin such as vinyl chloride resin, polyethylene resin, polypropylene resin or polycarbonate resin. It is a plate-shaped thing made from the material which has.

Note that the inclined surface 11 of the substrate 1 is
The plate-like body 3 so that the largest possible area of the plate is compressed.
Is preferably as large as possible with respect to the area of the inclined surface 11 of the substrate 1, and is generally at least １ ／ of the area of the inclined surface 11. However, the outer shape of the retroreflector 2 is not necessarily limited to the size of the inclined surface 11 or the plate-shaped body 3 of the substrate 1, and the outer shape is substantially the same as the size of the inclined surface 11 or the plate-shaped body 3. However, the retroreflector 2 may be attached with a plurality of retroreflectors 2 partially scattered on the inclined surface 11. For example, as shown in FIG. 2, the outer shape of the retroreflector 2 may be used to form a character or mark such as an arrow during construction or an arrow, and the retroreflector 2 having the shape may be attached.

The method of installing the road sign according to the present invention will be described. The present invention is applied to a road which is intended to prevent intrusion by making the traveling direction of a vehicle or the like face the inclined surface 11 on which the retroreflector 2 is attached. Any number of road markings may be placed as it is. At this time, it is not necessary to adhere to the road surface with an adhesive or the like, and since the substrate 1 is made of an elastic material, the coefficient of friction with the road surface is large, so that the vehicle or the like does not move even when riding on or by wind pressure. By being installed in this manner, the retroreflector 2 of the road marking body of the present invention is reflected by the headlights of the vehicle or the like, and the driver of the vehicle or the like can visually recognize the road marking body of the present invention.

[0019]

As described above in detail, the road sign according to the present invention has at least one upper surface of the substrate having an inclination angle of 5 with respect to the bottom surface.
The inclined surface rises in the range of 10 to 10 degrees, and the retroreflector is attached to the inclined surface, so that the reflected light of the retroreflector is easy to see from the traveling vehicle and has excellent visibility. The angle of inclination of the inclined surface is in the range of 5 to 10 degrees.
