DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reflector for a fence to be attached to a fence in order to improve the visibility of the fence at night.

[0002]

2. Description of the Related Art On a guardrail as a protective fence installed on a road shoulder, a reflecting sheet for reflecting a vehicle headlight is adhered to the surface so that the position of the shoulder can be easily recognized even at night. Some have a retroreflective coating on the surface.

[0003]

However, even if the reflective sheet is adhered to the surface of the guardrail or the retroreflective coating is applied as described above, the angle at which the headlight of the vehicle enters the retroreflective material is constant. In some cases, effective retroreflection cannot be obtained. In particular, when the guardrails are arranged in a positional relationship where the headlights of the vehicle are difficult to hit, or under bad conditions such as rainy weather, such a problem tends to become apparent.

An object of the present invention is to solve the above-mentioned problems of the prior art, and to provide a reflector for a protective fence that can be easily assembled and mounted and can improve the visibility of the protective fence at night. And

[0005]

SUMMARY OF THE INVENTION According to the present invention, there is provided a reflector for a guard fence, wherein a long lateral member is attached to a pillar arranged at a predetermined interval by a connecting fixture. A reflective member is rotatably fixed to one end of the cylindrical member so as to adjust the angle of the reflective surface.

According to this structure, the angle of the reflecting surface is adjusted to an optimum state by rotating the reflecting member so that the headlight of the vehicle is incident on the reflecting member at an angle at which the light is easily retroreflected. It is possible to improve the visibility of the protective fence in the area. Further, when the reflector is attached to the protective fence, it is only necessary to fix the reflector to the protective fence via the connecting fixture, so that the reflector can be easily attached.

According to another aspect of the present invention, there is provided a reflector for a protective fence, wherein a reflective member is fixed to an outer periphery of an annular member. Make a structure to tighten.

According to this configuration, since the angle of the reflecting surface of the reflecting member fixed to the outer periphery of the annular member changes continuously, no matter what angle the headlight light of the vehicle enters the reflecting member. Since the light is retroreflected on one of the reflecting surfaces, the visibility of the protective fence at night can be improved. Further, when the reflector is attached to the protective fence, it is only necessary to fasten the reflector together with the fastening member of the connecting fixture of the protective fence at the center hole of the annular member by the fastening member, which facilitates the attachment of the reflector.

According to another aspect of the present invention, a bar-shaped reflecting member is slidably inserted into a guide engaging portion formed along a longitudinal direction of a lateral member of the protective fence. It is configured such that the reflection surface is exposed.

According to this structure, the reflector is assembled only by slidingly inserting the bar-shaped reflector into the guide engaging portion of the lateral member, and the lateral member is connected to the support via the connecting fixture. If they are connected to each other, the protective fence can be assembled, so that the assembling and mounting of the reflector can be facilitated. Further, since this reflecting member is attached to the long transverse member, the area of the reflecting surface can be increased, and the visibility of the protective fence at night can be improved.

In the third embodiment, the guide engaging portion 51b is an opposing groove formed along the longitudinal direction of the horizontal member 51, and the bar-shaped reflecting member 31 is slidably inserted therein. Although a configuration example (see FIG. 6) is shown, the present invention is not limited to this, and the guide engagement portion is formed by opposed ribs formed along the longitudinal direction of the lateral member, and a bar-shaped It is also possible to adopt a configuration in which the grooves formed in the reflecting member 31 are slid and inserted together.

Although FIGS. 3 and 4 show a state in which all of the protective fence reflectors 10, 20, and 30 of each embodiment are attached to the protective fence 50, the respective reflectors 10, 20, and 3 are shown.
0 may be appropriately selected and attached to the protective fence 50.

[0037]

As described above, the reflector for a fence according to the present invention has a cylindrical body attached to the protective fence via a connecting fixture for the fence, and a reflecting member is provided at one end of the cylindrical body. Is rotatably fixed and the angle of the reflecting surface is configured to be adjustable. By rotating the reflecting member, the headlight light of the vehicle is reflected so as to be incident on the reflecting member at an angle at which retroreflection is likely to occur. By adjusting the angle of the surface to an optimal state, the visibility of the protective fence at night can be improved. In addition, when the reflector is attached to the protective fence, it is only necessary to fix the tubular member of the reflector to the protective fence via the connecting fixture, and the reflector can be easily attached.

[0038] Further, in another reflector for a protective fence, a reflective member is fixed to an outer periphery of an annular member. Since the angle of the reflecting surface of the reflecting member fixed to the outer periphery of the annular member changes continuously, the headlight light of the vehicle is incident on the reflecting member at any angle. Since the light is retroreflected by the reflecting surface, the visibility of the protective fence at night can be improved.
In addition, when the reflector is attached to the protective fence, it is only necessary to fasten the reflector together with the fastening member of the connecting fixture of the protective fence at the center hole of the annular member, and the reflector can be easily attached.

Further, in another reflector for a protective fence, a bar-shaped reflecting member is slidably inserted into a guide engaging portion formed along a longitudinal direction of a lateral member of the protective fence, and a reflecting surface of the reflecting member is provided. Is constructed so that a bar-shaped reflecting member only needs to be slid and inserted into the guide engaging portion of the lateral member to assemble the reflecting member. If it connects via, the protective fence will be assembled, and assembling and mounting of a reflector can be performed easily. In addition, since this reflection member is attached to a long transverse member, the area of the reflection surface can be increased,
The visibility of the protective fence at night can be improved.
