Description

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

The purpose of this invention is to rotate the rotating body using wind power and rotate the cylindrical body in contact with a cleaning material, to self-clean dust, dirt, etc. attached to the circumferential surface of the cylindrical body facing the reflective surface, and to The goal is to provide visual guides.

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 includes a support portion 11 for supporting a shaft 2, which will be described later.
．． 11 are provided protrudingly opposite to 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, and is provided between the support parts 11 and 11.

The shaft 2 is fixed between the supporting parts 11 and 11, and serves as the center of rotation of the cylindrical body 3 and the rotating body 5, which will be described later.

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

The cylindrical body 3 is rotatably provided around the shaft 2 as a central axis.

Further, a gear portion 32 is bored at the end of the cylindrical body 3, and is pressed by a blade piece 51 or a pressing portion 52 of a rotating body 5 which will be described later.

The gear part 32 may be made by providing unevenness on the outer peripheral edge of a disk and attached to the cylindrical body 3, or it may be made by forming concave and convex parts that are directly continuous on the end of the cylindrical body 3 to form a gear shape. You can leave it there.

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 provided 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 resin or acrylic resin with many diamond cuts on the back side is preferably used, but glass beads are used. An embedded synthetic resin reflective sheet or the like may also be used.

Further, the reflector 4 may be provided within the cylindrical body 3 so that the reflective surface faces the circumferential surface 31 of the cylindrical body 3.
The shape is not particularly limited.

For example, it may be in a cylindrical shape as shown in FIGS. 1 to 3, it may be in a plate shape, or it may be in a sheet shape that can be directly attached along the inner peripheral surface of the cylindrical body 3. good.

Further, a plate-shaped reflector 4 is fixed to the shaft 2 within the cylindrical body 3, so that its reflecting surface always faces in a fixed direction.

5 is a rotating body made of metal, synthetic resin, etc.;
It has a plurality of radial blade pieces 51, 51...

The blade piece 51 is shaped like a smooth plate, a curved plate, or the like.

Further, as shown in FIG. 1, a pressing part 52 may be provided protrudingly on any blade piece 51 to press the gear part 32 of the cylindrical body 3, or the blade piece 51 can directly press the gear part 32. It may be done as follows.

Further, the rotating body 5 is rotatably pivoted to a support shaft 7 provided directly or indirectly on the mounting base 1 so as to be substantially perpendicular to the shaft 2.

For example, in the case of FIG. 1, the support parts 11, 1 of the mounting base 1
1 are connected by a connecting rod 13, a supporting shaft 7 that is substantially perpendicular to the shaft 2 is provided on the connecting rod 13, and a rotating body 5 is pivotally mounted on the supporting shaft 7 facing the mounting base 1.

Further, the rotating body 5 may be provided at the upper or lower part of the cylindrical body 3 other than that shown in FIG. 1, and in both cases, the support shaft 7 is provided directly on the mounting base 1.

Further, it is preferable that the rotating surface of the rotating body 5 is arranged to face the mounting base 1, since the width of the sight guide is not increased.

6 is a cleaning material made of rubber, sponge, brush, etc.

The cleaning material 6 is fixed to the mounting base 1 and is always in contact with the circumferential surface 31 of the cylindrical body 30.

Next, to explain the function of the sight guide of the present invention, when wind pressure is applied to the blade pieces 51, 51 of the rotating body 5, the rotating body 5 rotates, and as the rotating body 5 rotates, the cylindrical shape body 3
The gear part 32 is pressed by the blade piece 51 or the pressing part 52, the cylindrical body 3 is rotated around the shaft 2, and the peripheral surface 31 of the cylindrical body 3 is rubbed by the cleaning material 6 to clean dust, dirt, etc. It is something that

In addition, especially when the reflector 4 is provided inside the cylindrical body 3, the cleaning material 6 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 includes a cylindrical body with a reflective function that is rotatable about the axis between the support parts of the mounting base, and a rotating body that has a plurality of radial blade pieces. However, as the rotating body rotates, the cylindrical body is pressed by the blade pieces and rotates, and the circumferential surface of the cylindrical body is in contact with the cleaning material fixed to the mounting base. Dust, dirt, etc. attached to the circumferential surface of the cylindrical body can be automatically cleaned by wind pressure.

In addition, since the circumferential surface of the transparent cylinder is a reflective surface or a reflector is installed inside the cylinder, and the reflective surface of the reflector is opposed to the circumferential surface, the width as a line-of-sight guide can be reduced. By increasing the length of the cylindrical body in the axial direction, it is possible to secure a sufficient reflective area to exhibit reflective performance without increasing the size. The projecting dimension to the side is small and there is no possibility of contact with the vehicle.

Furthermore, since the rotating body having a plurality of radial blades is rotatably pivoted to the shaft that supports the cylindrical body and the support shaft is at right angles to the support shaft, the rotating surface of the rotating body should face the mounting base. By increasing the length of the blade pieces, the rotating body can be rotated even with slight wind pressure while keeping the width as a line guide narrow as described above.
