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 driver's gaze.

[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 disk-shaped reflector is used, 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 that snow, dust, dirt, etc. tend to adhere, and the effect of guiding the line of sight tends 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.

An object of the present invention is to provide a gaze marker for roads that solves the above conventional problems.

[0005]

SUMMARY OF THE INVENTION According to the present invention, a plurality of reflectors are mounted side by side along a length direction on a side surface of a column to increase a reflection area, and the reflecting surface of each reflector is convexly curved. 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 of the reflector and the oblique direction.

[0006] That is, the road gaze marker for road according to the present invention comprises a plurality of reflectors mounted side by side along a length direction on a side surface of a pillar, and the pillar includes at least a pair of pillars along the length direction on the pillar body. The 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, and the curved surface of the reflector main body of an appropriate length is used as the reflection surface, and along both sides of the reflector main body. Protrusions are provided, the protrusions on both sides of each reflector are held by a pair of holding pieces, and a plurality of reflectors arranged in the vertical direction are attached to the lower end side of the support and the support. It is fixed by being sandwiched between a cap attached to the upper end of the.

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 pillar, which is made of metal or the like, and at least a pair of holding pieces 12 are provided to be opposed to and protrude from a pillar body 11 along the length direction. The column main 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 main body 11 is not limited to this, and may be an appropriate shape such as a triangle, a polygon, a circle, or another irregular 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 to each other. 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-split vertical cylinder 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.

The reflectors 2 are slid along the pillars 1 with their both side projecting edges 23 being held by the holding pieces 12 forming a pair with the pillars 1 and arranged in the vertical direction so that a plurality of them are stacked as shown in FIG. It is attached to the column 1. The reflector 2 may be attached only to the front side surface of the support column 1, both front and rear side surfaces, or side surfaces as required.

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 portion of the column 1 are sandwiched and fixed.

The support material 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 projecting edges 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 forming 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 other fixing methods may be appropriately adopted.

When the supporting member 3 is in the shape of a substantially half-vertical cylinder similar to the reflector 2, the supporting member 3 having an appropriate length is used according to the length of the support column 1 and the number of reflectors 2 to be mounted. It should be done. In addition, the support material 3 is not limited to the above, 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 side surface of the pillar, the sighting guide mark for road according to the present invention can easily increase the reflection area. It is possible to improve the gaze guidance effect at night.

Further, since the reflecting body has the curved surface of the reflecting body having an appropriate length and having a convex section in the shape of a curved plate, the reflecting surface is not limited to the light from the front direction of the reflecting body. 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, the two projecting edges of each reflector are held by a holding piece forming a pair of columns, and a plurality of reflectors arranged in the vertical direction are provided on the lower end side of the column and the supporting member. Since it is sandwiched and fixed to the cap attached to the upper end portion, the reflector can be easily attached and the number of the attached reflectors can be easily changed as required.
