Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a median strip line-of-sight guide that is suitably installed on a median strip of a road in a snowfall area.
[0002]
[Prior art]
A line-of-sight indicator that guides the line of sight of a vehicle driver by reflecting the light of the headlights of the vehicle with a reflector at night or the like is installed in the median strip of the road. As one form of this gaze guide mark, for example, as shown in FIG. 5, a horizontal pole b composed of a cylinder is joined to the upper end of a column a in a substantially T-shape, and attached to a frame c at both left and right ends of the horizontal pole b. A reflector d having a diameter of about 100 mm is attached, and the positions of the left and right reflectors d are adjusted to the width of the median strip e, so that the driver can recognize the position of the median strip e during snowfall and guide the eyes. There are things that are made to do.
[0003]
[Problems to be solved by the invention]
However, the gaze guide marker as described above is such that when the snow falls because the horizontal pole b is a cylinder, the snow easily falls on the horizontal pole b and also on the frame c of the reflector d. There is a problem that the visibility of the reflector d decreases when the snow eaves develop due to the snow cover and cover the surface of the reflector d. The reflectors d are attached only to the left and right ends of the horizontal pole b, and the visibility is not sufficient because the reflectors d at the left and right ends only reflect in a spot shape even when snow is not covered. .
[0004]
SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and has an object to provide a gaze guide mark for a median strip which is hard to cover snow and has excellent visibility.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the present invention has the following configuration.
That is, in the gaze guide marker for the median strip according to the present invention, the horizontal housing is joined to the upper end of a column erected substantially at the center of the median strip in a substantially T-shape across the median strip. The cross section has a one-sided flow shape from the top to the bottom, has a length substantially equal to the width of the median strip, and both ends of the horizontal housing indicate the boundary of the median strip, and the front side of the horizontal housing or A plurality of reflectors are mounted side by side on the front and rear sides along the length direction, and the plurality of reflectors reflect the full width of the central separator .
[0006]
According to the present invention, since the cross section of the horizontal housing has a one-sided flow shape from the upper part to the lower part, the snow piled on the upper part of the horizontal housing is imbalanced. Can be prevented. Also, a plurality of reflectors are mounted side by side along the length direction on the front side surface or the front and rear side surfaces of the horizontal housing, and the reflection area is large and the light is reflected along the length direction, so that night visibility is improved. Can be.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, embodiments of the present invention will be specifically described with reference to the drawings.
FIG. 1 is a front view showing an embodiment of the present invention, FIG. 2 is a side view thereof, FIG. 3 is a side view showing another embodiment of the present invention, and FIG. It is.
[0008]
In the drawings, reference numeral 1 denotes a column standing upright at a substantially central portion of the median strip C, and is formed of an appropriate material such as metal. Reference numeral 2 denotes a horizontal housing, which is joined and supported at the upper end of the column 1 so as to form a substantially T-shape across the median strip C. The length of the horizontal housing 2 is approximately the width of the median strip C so that both ends of the horizontal housing 2 indicate the boundaries of the median strip C. Even if the median strip C is buried by snow, the horizontal housing 2 is horizontal. By looking at the housing 2, the boundaries can be seen.
[0009]
The cross-sectional shape of the horizontal housing 2 is a one-sided flow shape from the upper part to the lower part, that is, a right-angled triangular shape in which the front surface is a vertical surface and the rear surface is an inclined surface, and is formed on the front surface as shown in FIG. A plurality of reflectors 3 are mounted side by side in the opened portion 21 in the direction of the line of sight of the vehicle driver. The reflector 3 may be attached to both front and rear sides as shown in FIG. 3 so as to be visible from both the traveling vehicle and the oncoming vehicle. Further, each reflector 3 may be mounted without a gap, or may be mounted with an appropriate gap.
[0010]
The one-sided flow shape of the horizontal housing 2 is such that a substantially triangular shape is formed by the front side surface and the rear side surface as shown in FIG. 4, and the inclination angles x and y of the two side surfaces are different from each other. By doing so, the snow piled on the top is not well balanced, so that the snow falls before the snow cover becomes large. Since the angle of repose of snow is about 50 degrees at −3.5 ° C., the angles x and y are preferably set to 50 degrees or more.
[0011]
The material for forming the horizontal housing 2 is not particularly limited, and suitable materials such as metals such as aluminum alloys and steels, and synthetic resins such as polyethylene, ABS resin, FRP, polycarbonate, and AAS are used. The use of polycarbonate is preferred because even if snow adheres, it is easily peeled off.
[0012]
The reflector 3 has a rear surface that is prism-finished and a front surface that is normally a smooth surface. When light from a vehicle headlight is received, the light is retroreflected in the vehicle direction by a prism on the rear surface. The shape may be round or square, and is not particularly limited.
[0013]
The reflector 3 is generally obtained by molding synthetic resin such as polymethyl methacryl, methacrylic resin, polycarbonate, polystyrene, acrylic resin and the like having excellent translucency by injection molding or the like.
[0014]
【The invention's effect】
According to the present invention, the cross section of the horizontal housing has a one-sided flow shape from the upper part to the lower part. Can be prevented. Also, a plurality of reflectors are mounted side by side along the length direction on the side surface of the horizontal housing, and the reflection area is large and the light is reflected along the length direction, that is, at the full width of the median strip. Can be improved.
