Description

[Detailed explanation of the idea] This invention relates to a self-cleaning visual guide.

Conventionally, in this type of line-of-sight guide, a rotating body having a plurality of radial blades is pivoted on the surface of a circular reflector, and a wiper supported by the blades moves around the reflector as the rotating body rotates. The dirt on the surface of the reflector is cleaned by rubbing the surface of the reflector.

However, since the reflector of such a line-of-sight guide is circular and a rotating body is pivoted on the surface of the reflector, the diameter of the reflector or rotating body becomes the width of the line-of-sight guide, which improves the reflective performance of the reflector. In order to have a sufficient reflective area for effective use, the diameter must be increased, and the width of the visual guide also increases, especially when installed in a place where the road width is restricted, such as in a tunnel. etc., the projecting size toward the road side becomes large, and there is a drawback that it is easy to come into contact with vehicles.

In view of these conventional drawbacks, the present inventor has made extensive efforts to provide a self-cleaning line-of-sight guide that eliminates the above-mentioned drawbacks.

An embodiment of the present invention will be described below with reference to the drawings.

In the drawings, reference numeral 1 denotes a mounting base, which is in the form of a plate, a rod, or the like made of an inorganic material, metal, or the like.

The mounting base 1 has a support portion 1 for fixing a shaft 2, which will be described later.
1.11 are protruded from each other at appropriate intervals.

Note that 12 is a mounting hole. Reference numeral 2 denotes a shaft, which is made of metal or the like, is fixed between supporting parts 11 and 11, supports a cylindrical body 3 to be described later, and serves as a center of rotation for the rotating body 5 and the cleaning body 6.

3 is a transparent cylindrical body made of synthetic resin such as polycarbonate resin or acrylic resin, strong glass, or the like.

The cylindrical body 3 is fixed to the shaft 2 with the shaft 2 as the central axis.

Further, the cylindrical body 3 may have, for example, a large number of diamond cuts on its inner circumferential surface so that the circumferential surface 31 serves as a reflective surface, or a reflector 4, which will be described later, may be attached inside the cylindrical body 3 and the reflector 4 may be The reflective surface is arranged to face the circumferential surface 31 of the cylindrical body 3.

4 is a reflector, and a plate-shaped or cylindrical body made of synthetic resin such as polycarbonate I resin or acrylic resin with many diamond cuts on the back side is preferably used. It may also be a synthetic resin reflective sheet in which glass beads are embedded.

Further, the reflector 4 may be attached within the cylindrical body 3, and its shape is not particularly limited as long as the reflective surface faces the circumferential surface 31 of the cylindrical body 3.

For example, it may be in the shape of a rectangular plate as shown in FIGS. 1 and 2, it may be in the shape of a cylinder, or it may be in the form of a sheet that can be directly attached along the inner peripheral surface of the cylindrical body 3. You can.

5 is a rotating body made of metal, synthetic resin, etc.;
It has a plurality of radial blade pieces 51, 51, . . . , and a pressing piece 52 is rotatably attached to any of the blade pieces 51.

Further, the blade piece 51 is formed into a smooth plate shape, a curved plate shape, or the like.

The rotating body 5 is provided on at least one of the upper and lower parts of the cylindrical body 3 with the shaft 2 as the center of rotation, and as the rotating body rotates, the suppressing pieces 52 rotate outward due to the action of centrifugal force, which will be described later. A pressing force is applied to the cleaning body 6 of.

Reference numeral 6 denotes a cleaning body, which is formed from a holding material 61 and a cleaning material 62.

The holding member 61 is made of metal, synthetic resin, or the like, and is shaped like an elongated plate or rod, and has both ends bent and loosely fitted to the upper part of the cylindrical body 3 and the upper shaft 2 .

The cleaning material 62 is made of rubber, sponge, brush, etc.
It is attached to the holding member 61.

That is, the cleaning body 6 is provided on the outer periphery of the cylindrical body 3 with the shaft 2 as the center of rotation, and the cleaning body 6 is attached to a holding member 61.
2 is in contact with the circumferential surface 31 of the cylindrical body 3.

Also, to explain the rotation of the cleaning body 6, when the blade pieces 51, 51 of the rotary body 5 receive wind pressure, the rotary body 5 rotates.
rotates, and as the rotating body 5 rotates, the pressing piece 52 is rotated outward by the action of centrifugal force, and the protrusion 6 of the holding member 61 is rotated.
3 is pressed by a pressing piece 52, the cleaning body 6 is rotated around the shaft 2, and the peripheral surface 31 of the cylindrical body 3 is rubbed by the cleaning material 62 to clean dirt and the like.

Further, the cleaning body 6 may have a shape as shown in FIGS. 1 to 3, or may have a shape as shown in FIG. 4 and be rotatable about the shaft 2.

In addition, especially when the reflector 4 is installed inside the cylindrical body 3, the cleaning material 62 does not directly rub the surface of the reflector 4 and does not damage the reflector 4. It is preferable because the reflection performance can be maintained in a good state.

As detailed above, the visual line guide of the present invention is fixed between the supporting parts of the mounting base, and the peripheral surface of the cylindrical body serves as a reflective surface, or a reflector is installed inside the cylindrical body, and the reflective surface of the reflector is A rotating body facing the circumferential surface and having an axis as the center of rotation is provided at least on either the upper or lower part of the cylindrical body,
A cleaning body is provided on the outer periphery of the cylindrical body, with the axis as the center of rotation.
The cleaning body is pressed by the pressing piece of the rotating body so that the cleaning material contacts the circumferential surface of the cylindrical body and rotates.
By increasing the length of the cylindrical body in the axial direction, a sufficient reflective area can be secured to demonstrate reflective performance without increasing the width of the line-of-sight guide mark as in the past, which limits the width of roads in tunnels, etc. Even if it is installed in a location where it is used, the amount of overhang to the road side is small and there is no chance of it coming into contact with vehicles.

In addition, since the rotating body has a plurality of radial blades with the axis between the support parts of the mounting base as the center of rotation, it is easy to rotate against wind from all directions, promoting rotation of the cleaning body and increasing the cleaning effect. be able to.
