Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gaze marker for a road which is installed on a road shoulder, a median strip or the like and reflects light from a vehicle at night to guide the sight line of a vehicle driver.

[0002]

2. Description of the Related Art Conventionally, as a gaze marker for roads, for example, a disc-shaped retroreflective reflector is attached to a housing provided at the upper end of a pillar, or a rectangular plate-shaped retroreflection along the pillar. Some have a reflective reflector attached.

[0003]

However, when the former disc-shaped reflector is provided, the size of the reflector, in other words, the reflection area is limited, and there is a limit to the gaze guidance effect at night. It was Further, in the case of having the latter rectangular plate-shaped reflector, it is an attempt to solve the former problem by increasing the reflection area, but since the reflector is a flat plate, There is a problem in that snow, dust, dirt, etc. are likely to adhere, and the gaze guidance effect is likely to deteriorate. Moreover, only the light from the front direction of the reflector is reflected, and the line-of-sight guidance effect is not always sufficient.

It is an object of the present invention to provide a gaze guide for roads that solves the above-mentioned conventional problems.

[0005]

According to the present invention, a plurality of reflectors are mounted side by side along the length direction on the front and back of a column to increase the reflection area, and the reflecting surface of each reflector is curved in a convex shape. As a surface, while suppressing the adhesion of snow, dust, dirt, etc.,
This is to improve the line-of-sight guidance effect by making it possible to reflect the light from the front and oblique directions of the reflector.

[0006] That is, the road gaze marker for roads of the present invention comprises a plurality of reflectors mounted side by side along the length direction on the front and back sides of the support column, and the support column extends along the length direction on each side of the support column. At least a pair of holding pieces are provided so as to be opposed to each other, and the reflector has a curved plate shape with a convex cross section. A projecting edge is provided along with, and projecting edges on both sides of each reflector are held by a pair of holding pieces on the front and back of the column, and a plurality of vertically aligned reflectors are attached to the lower end side of the column. It is sandwiched and fixed between a support member and a cap attached to the upper end of the support.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. In the drawings, reference numeral 1 denotes a column, which is made of metal or the like, and at least a pair of holding pieces 12 are provided so as to face each other on the front and back sides of the column main body 11 along the length direction. The column body 11 is generally formed by connecting two flat plates 13 facing each other in parallel or diagonally as shown in FIGS. The shape of the pillar body 11 is not limited to this, and may be an appropriate shape such as a triangle, a polygon, a circle, or another shape.

The holding piece 12 is generally an elongated plate piece having a hook-shaped cross section. In the case of FIGS. 2 and 5, the holding pieces 12 are provided so as to be opposed to both side edges of the flat plate 13, but they are simply provided as appropriate pairs on the side surfaces of the column main body 11 so as to be provided so as to be opposed thereto. It may have been done.

Reference numeral 2 is a reflector, which is made of synthetic resin or the like. In the reflector 2, the curved surface of the reflector main body 21 having an appropriate length, which is a curved plate having a convex cross section, serves as a reflecting surface, and has a substantially half-vertical cylindrical shape. The reflecting surface is generally formed by providing a large number of prismatic irregularities 22 on the inner surface of the reflector body 21, but it may be formed by another method. At the upper and lower ends of the reflector main body 21, as shown in FIG. 4, a protective cover 24 that closes the upper and lower open end portions of a half-vertical cylindrical shape is provided to prevent water and dust from entering inside.

As shown in FIG. 4, projecting edges 23 are provided on both sides of the reflector body 21 so as to project outward along the length direction. As shown in FIGS. 2 and 5, the projecting edge 23 is held by the holding pieces 12 forming a pair of the support columns 1.

In the reflector 2, the protrusions 23 on both sides of the reflector 2 are on the surface of the pillar 1.
It is embraced by the retaining pieces 12 forming the back of the pair being slid along the column 1, that is attached to the post 1 arranged in as vertically stacking a plurality as shown in FIG. 1.

The plurality of reflectors 2 arranged in the vertical direction are
As will be described later, the support member 3 attached to the lower end side of the column 1.
And a cap 4 attached to the upper end of the column 1 is sandwiched and fixed.

The support member 3 is made of metal, synthetic resin or the like, and generally has an outer shape similar to that of the reflector 2 from the viewpoint of aesthetics. That is, as shown in FIG. 3, the protrusions 32 are provided on both side edges of the support member main body 31 having a substantially half-vertical shape.
A stopper portion 33 is provided on the inner surface of 1.

In this support member 3, the projecting edges 32 on both sides are the support columns 1.
The holding portion 33 is held by the holding piece 12 that forms a pair.
Is abutted on the side surface of the column 1, is positioned on the lower end side of the column 1, and supports the lowermost reflector 2.
The support member 3 is fixed to the support column 1 by the bolt 5 penetrating the support member 3 and the support column 1 as shown in FIGS. 1 and 3, but another fixing method may be appropriately adopted.

When the support member 3 is in the shape of a substantially half-vertical cylinder similar to the reflector 2, the support member 3 has an appropriate length depending on the length of the support column 1 and the number of reflectors 2 to be attached. It should be done. In addition, the support material 3 is not limited to the above-mentioned material, and may be a member having another shape appropriately fixed to the support 1 to support the reflector 2 at the bottom.

The cap 4 is made of metal, synthetic resin or the like, and is attached to the upper end of the column 1 with screws 6 as shown in FIG. The cap 4 covers the upper end surface of the column 1,
It is provided to prevent the uppermost reflector 2 from coming off. The shape of the cap 4 is not particularly limited as long as it has the above-described effects.
As for the attachment of the cap 4, an appropriate method other than screw fixing such as adhesion or welding may be adopted.

[0017]

As described above in detail, since the plurality of reflectors are mounted side by side along the length direction on the front and back of the pillar, the gaze marker for road according to the present invention can easily increase the reflection area. co If it is possible to improve nighttime visual guidance effect Te
In addition, a reflector suitable for the driving lane is attached to the front side of the pillar body
On the back side of the pillar body, attach a reflector suitable for the opposite lane
Optimal reflection for each front and back of the main body of the pillar
Can be attached to the body.

Further, since the reflector has a curved surface of a reflector main body of a proper length which is formed in a curved plate shape having a convex cross section, the reflecting surface is not limited to the light from the front direction of the reflector. Also, light from an oblique direction can be reflected, and night visibility can be improved. Moreover, snow, dust, dirt, etc. are unlikely to adhere to the curved surface of the reflector, and the line-of-sight guidance effect does not deteriorate as in the conventional case.

Further, both side edges of each reflector are firmly held by being held by a pair of holding pieces on the front and back sides of the support , and used.
A plurality of reflectors that do not float or fall off from the main body of the column and that are arranged vertically are sandwiched between the support material attached to the lower end of the column and the cap attached to the upper end of the column. Since they are fixedly attached, the reflectors can be easily attached, and the number of attachments can be easily changed as required.
