Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a road sign, and more particularly to an antiglare plate for preventing glare from headlights of oncoming vehicles and a reflector for indicating road conditions by reflected light from the headlights. It is related to the combined signs.

[0002]

2. Description of the Related Art Conventionally, when an automobile travels at night, a reflector for reflecting a light beam of a headlight to indicate to a driver the condition of a road curve and the like and a reflector in series with the road. A method of arranging and displaying road information is known. Further, an antiglare plate for preventing glare from headlights of oncoming vehicles and a method of disposing the antiglare plates in a row on a road to prevent the glare are also known.

[0003]

However, in the above-mentioned conventional technique, the reflector and the antiglare plate must be separately arranged, and the cost for the arrangement and the security management after the arrangement is required. There was a problem that was high. In particular, considering the road situation in Japan where there are many mountainous areas, there are many places where it is necessary to dispose a reflector and an antiglare plate, and it can be said that such a problem is very serious. Moreover, it is even more so in recent years when resource conservation issues are of great concern to the general public. Further, disposing both the individual reflection plate and the antiglare plate in the same area may be difficult to install depending on the road environment. Further, the antiglare plate needs a certain area to shield the light beam of the headlight of an oncoming vehicle, and therefore, the wind pressure generated when an automobile, especially a large car, passes near the antiglare plate prevents the light from being blocked. There was also a problem that the glare plate vibrates.

Therefore, in view of the above-mentioned conventional problems, the present invention does not require the reflector and the antiglare plate to be separately provided, and can reduce the vibration due to the wind pressure of the automobile. It is a technical subject to provide a visual gaze guidance sign.

[0005]

In order to achieve the above object, the present invention takes the following means. That is, the invention of claim 1 is a reflection type line-of-sight guidance sign including at least an antiglare plate and a reflector, wherein the reflector is provided on a part of the front surface and the back surface of the antiglare plate, or on the front surface or the back surface. The anti-glare plate and the reflector are integrally formed by arranging them in a part of either one. Further, the invention of claim 2 is the reflection type visual line guidance sign of claim 1, wherein the antiglare plate is provided with one or more wind vent holes. The invention of claim 3 is the same as claim 1 or claim 2.
The reflective gaze guidance signs are arranged in a line at the center line or the median strip of the road.

[0006]

As described above, according to the first aspect of the present invention, since the reflector is disposed as an integral structure on a part of the antiglare plate, one reflection-type line-of-sight guidance sign is provided with the reflector and the anti-glare plate. It will have both the role of the glare plate.

According to the second aspect of the invention, since the antiglare plate is provided with one or more wind vent holes, the wind generated when the vehicle passes near the antiglare plate is the wind vent hole. By passing through to the back of the antiglare plate, the wind pressure is reduced and the vibration of the antiglare plate is prevented.

Further, since the invention of claim 3 has a constitution in which a plurality of the reflection type visual line guidance signs of claim 1 or 2 are arranged in a line on the central line of the road, the road is curved. While preventing dazzling by the headlight of the oncoming vehicle at the time of turning, road information such as a curve is simultaneously marked by the reflector.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. The reflection-type gaze guidance sign of this example mainly has a structure in which an antiglare plate 1 having a reflector 2 and a wind vent 3 is attached to a column 5 via a holding member 4.

The antiglare plate 1 is formed of a substantially rectangular plate body having a desired area. And, in a part of the front surface and the back surface of the anti-glare plate 1, in this example, the upper center portion,
A reflector 2 is provided. The reflector 2 is formed by fixing a reflecting material, such as a yellow or red plastic material, which sufficiently reflects the light rays of the automobile headlight, by a suitable fixing means such as sticking so as to have a predetermined area. There is. The reflector 2 may be formed by coating glass particles, or may be configured by screwing a plate-shaped reflector such as plastic to the antiglare plate 1.
The wind vent holes 3 are provided by forming a plurality of slit-shaped antiglare plates 1 in the lower portion of the reflector 2 in parallel. As shown in FIG. 3, the wind vent 3 has a notch in the antiglare plate 1, and the notches are alternately cut and raised toward the front surface side and the back surface side of the antiglare plate 1 so that the cross section is substantially L-shaped. It is formed by cutting and raising while forming the shape of, and opening and piercing the antiglare plate 1 so as to form the shielding portion 3a by bending the tip edge. Here, the shielding portion 3a shields the slit-shaped opening of the air vent hole 3 without obstructing passage of the wind, thereby preventing dazzling in the opening. In addition, on both left and right ends of the antiglare plate 1,
In order to mount the antiglare plate 1 on the holding member 4 which will be described later, a hole (not shown) through which the antiglare plate mounting bolt 6 penetrates is provided.

The holding member 4 has an antiglare plate holding portion 4a on which the antiglare plate 1 is attached and a column mounting portion 4b on which the column 5 is attached.
