Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-cleaning device for a gaze guide attached to a gaze guide installed on a shoulder of a road, a median strip, or the like to wipe off dirt attached to a reflector. It is about.

[0002]

2. Description of the Related Art A gaze guide mark is provided on a road shoulder, a median strip, or the like on a road to guide a gaze of a vehicle driver by reflecting light of a vehicle headlight by a reflector at night or the like. However, since this line-of-sight guide is installed at a height that easily receives the exhaust gas of the vehicle, dirt such as the exhaust gas of the vehicle or dust easily adheres to the reflector.
When dirt adheres, there is a problem that the reflection performance is reduced.

[0003] Therefore, as described in, for example, Japanese Utility Model Publication No. 55-27885, a blade piece is attached to the front surface of a reflector, and the blade piece is rotated by wind force, so that the wiper attached to the blade piece can be used. There has been proposed a so-called self-cleaning line-of-sight guide that automatically cleans the reflector surface.

[0004]

However, this gaze guide mark has a complicated mechanism, resulting in an increase in cost, wear of the rotating shaft and adhesion of dirt, resulting in poor rotation, and furthermore, the blade pieces are incorporated into the reflector. In the case of poor rotation or breakage, the blade piece cannot be replaced alone, and the entire gaze guide including the blade piece must be replaced, so the blade piece must be replaced with the existing line of sight. It is also very difficult to retrofit the guidepost and make it self-cleaning type, and it cannot cope with a rectangular reflector.

[0005] Therefore, a large number of filaments are suspended like a curtain slightly in front of the reflector, and the filaments are made to flow by the wind and slide on the surface of the reflector, thereby automatically removing dirt on the reflector. A retrofitting self-cleaning device adapted to be wiped off is also proposed. However, since the filaments are disturbed in all directions by the wind and fly up, they cannot be efficiently slid into contact with the surface of the reflector. Particularly, in the case of a large reflector having an outer diameter of 200 mm or 300 mm, the reflector has a large diameter. It was almost impossible to make a uniform sliding contact with the surface.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems and to provide a self-cleaning device for a gaze guide target that can be easily attached to an existing gaze guide and that can efficiently wipe off dirt on a reflector. Things.

[0007]

In order to achieve the above object, the present invention has the following arrangement. That is, the self-cleaning device for a gaze guide according to the present invention is a self-cleaning device attached to the gaze guide and for wiping off dirt adhering to the reflector, and a support adapted to be attached to the gaze guide. One or a plurality of strip-shaped elastic thin plates are attached to the body, and one end of the elastic thin plate is fixed to a support and is dispersed and disposed slightly in front of the reflector. When the wind blows, it is possible to swing along the surface of the reflector with the fixed end as a fulcrum, and the wiping body that is slidably contacted with the surface of the reflector is attached to the elastic thin plate. It is a feature.

According to the present invention, when a natural wind or a wind generated at the time of passing a vehicle blows, the elastic thin plate swings along the surface of the reflector due to the wind, and the wiping member attached to the elastic thin plate is swung. Wipe the surface of the reflector. The elastic thin plate does not fly up and down in all directions like the conventional filament, but swings along the surface of the reflector, so that the wiping body is securely slid on the surface of the reflector, and the reflector is efficiently stained. Can be dispelled.
Further, since the elastic thin plate has a larger area for receiving the wind compared to the filament, the elastic thin plate swings with a relatively small wind, and it is also possible to efficiently wipe off the dirt on the reflector.

Further, since the elastic thin plate has a weight attached to the tip and is swingable like a pendulum with the fixed end as a fulcrum, even a large reflector or a square reflector is uniform. Can be wiped off. Further, the structure is simple, so that there are few failures, the cost is low, and it can be retrofitted, can be attached to an existing gaze guide at the site, and maintenance in case of breakage is easy.

[0010]

Next, an embodiment of the present invention will be specifically described with reference to the drawings. First, FIG. 1 is a front view showing an embodiment in a state where the present invention is mounted, FIG. 2 is a side view thereof, and FIG. 3 is a rear view.

In FIGS. 1 to 3, reference numeral 1 denotes a line-of-sight guide mark, and a synthetic resin such as an acrylic resin or a polycarbonate resin is mounted on a housing 12 made of a synthetic resin or metal which is fitted and attached to the upper portion of a support 11. Reflector 1 made of
Reference numeral 3 denotes a known device supported on the front surface or both front and rear surfaces. The shape of the reflector 13 may be round or square, and the shape is not particularly limited. The rear surface of the reflector 13 is subjected to prism processing and the surface is usually made a smooth surface. When light from a vehicle headlight is received, the light is retroreflected in the vehicle direction by the prism on the rear surface.

Reference numeral 2 denotes a self-cleaning device according to the present invention mounted on the line-of-sight guide 1, and a support 3 mounted on the housing 12 and 1 mounted on the support 3.
And a plurality of strip-shaped elastic thin plates 4.

The support 3 is attached to the back of the housing 12 with an adhesive or a double-sided adhesive tape or the like, and protrudes above the housing 12. One end of the attachment 31 has a bolt 32 and a nut 33 at one end. And a support portion 34 that projects forward of the reflector 13 across the housing 12.

The elastic thin plate 4 is formed of a self-supporting strip-shaped plate material having spring elasticity, and its front and back surfaces are perpendicular to the surface of the reflector 13, and one end of the elastic thin plate 4 is supported by the support portion 34.
It is fixed to the front end and is mounted slightly forward of the reflector 13, and the reflector 1 extends from the fixed end toward the front end.
3 are distributed radially downward so as to be distributed over the entire surface of 3. Further, a weight 5 is attached to the tip of each elastic thin plate 4, and when wind blows and the front and back surfaces of the elastic thin plate 4 receive wind, the weight 5 bends around the fixed end as a fulcrum, and In such a manner that it swings right and left along the surface of the reflector 3.

The material of the elastic thin plate 4 is not particularly limited as long as it has spring elasticity. Generally, a stainless steel plate, a painted iron plate, a synthetic resin plate or the like is used. Plates are preferred. When formed from a stainless steel plate, the thickness thereof is preferably about 0.1 to 0.8 mm so that it easily bends and swings. Become. Further, the elastic thin plate 4 may be curved in a cruciform shape or the like so as to easily receive the wind.

It is preferable that the length of the elastic thin plate 4 is set so that the respective weights 5 are located outside the outer periphery of the reflector 13, and the width affects the area receiving the wind, but is too wide. Then, it becomes heavier in weight and hinders swinging. Therefore, the reflector 13 needs to have a relatively wide width so as to receive the wind well, but the reflector 13 having a small size preferably has a small width. Also, the number of the elastic thin plates 4 is usually set to about 1 to 6 because if the number of the elastic thin plates 4 is too large, the reflection surface is concealed and becomes difficult to see.

Reference numeral 6 denotes a wiping member attached to a side edge of the elastic thin plate 4 on the reflector side and slidably in contact with the surface of the reflector 13. When the elastic thin plate 4 swings due to wind, the wiping member 6 is moved. The surface of the reflector 13 is slid in contact with the surface of the reflector 13 to wipe off dirt attached to the reflector 13 for cleaning. The wiping body 6 is not particularly limited as long as it wipes off dirt attached to the surface of the reflector 13 by sliding contact. The wiping body 6 is formed of an appropriate material such as rubber, sponge, or brush.

When the wiping body 6 is strongly contacted with the surface of the reflector 13, the free swing of the elastic thin plate 4 is hindered. On the contrary, when the wiping body 6 is loosely contacted, dirt cannot be wiped off well. It is preferable that the distance from the surface of the reflector 13 can be finely adjusted. As a method of making fine adjustment, a bolt insertion hole 35 of a support part 34 attached to a tip of an attachment part 31 by a bolt 32 and a nut 33 is formed as an elongated hole in the support 3, and the support part is provided with respect to the reflector 13. 34 is attached so as to be able to advance and retreat in the front-rear direction, and by moving this support part 34 back and forth within the range of the long hole, the distance between the elastic thin plate 4 and the surface of the reflector 13 can be finely adjusted. I just need.

Next, FIG. 4 is a front view showing another embodiment according to the present invention. Compared with the above embodiment, the support 3 is directly adhered to the lower surface of the reflector 13 and A plurality of elastic thin plates 4 are fixed at one ends thereof and are mounted slightly forward of the reflector 13, and the elastic thin plates 4 are radially dispersed upward from the fixed ends toward the front end. The only difference is that a weight 5 is attached to the tip end thereof, and the rest is the same as the above-described embodiment. In this embodiment, the reflecting surface of the reflector 13 is somewhat concealed by the support 3, but there is an advantage that the structure can be simplified by forming the support 3 with a suction cup or the like.

[0020]

According to the present invention, when a natural wind or a wind generated when passing through a vehicle blows, the elastic thin plate receives the wind and swings, and the wiping member attached to the elastic thin plate cleans the surface of the reflector. Dispel. Since the elastic thin plate does not flutter and disperse in all directions like the conventional filament, it swings along the surface of the reflector,
The wiping body is reliably brought into sliding contact with the surface of the reflector, so that dirt on the reflector can be efficiently wiped. Further, since the elastic thin plate has a larger area for receiving the wind compared to the filament, the elastic thin plate swings with a relatively small wind, and it is also possible to efficiently wipe off the dirt on the reflector.

Further, since the elastic thin plate has a weight attached to the tip and is swingable like a pendulum with the fixed end as a fulcrum, even a large reflector or a square reflector is uniform. Can be wiped off. Further, the structure is simple, so that there are few failures, the cost is low, and it can be retrofitted, can be attached to an existing gaze guide at the site, and maintenance in case of breakage is easy.
