DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gaze guide using reflection of vehicle light, and more particularly to an apparatus for controlling snow during snowfall.

[0002]

2. Description of the Related Art It is not uncommon for line-of-sight signs installed at various points on a road to travel for a long distance, and the reflection function is lost due to the adhesion of snow when snow falls. Other than the snow removal measures described above, there is almost no equipment for controlling the equipment itself, which may cause a wide area and long-term impairment of traffic safety.

[0003] Considering the presence or absence of existing or already proposed snow protection related technology for the reflection type which is most frequently used as a gaze guide, the "gaze guide" according to Japanese Utility Model Publication No. It is a method of cleaning dust and dirt by providing a device that rotates a plurality of blade pieces using the device.However, since the wiper attached to each blade piece applies a resistance for sliding on the mirror surface, it is rotated. It is evident that there is a limit to the starting and rotational speed of the snow, and therefore it cannot be excluded during snowfall where snowflakes stick and accumulate continuously or as needed, and the blades rotate upwards when stopping, so It was difficult to cope with this device because of the possibility of snow accumulation.

[0004] Next, in the "line of sight guide" by Japanese Utility Model Publication No. 59-34572, the reflector is covered with a transparent case, and the top of the case is protected to prevent dirt such as exhaust gas, mud splashes, dust and the like. A rotor having a plurality of blades utilizing wind power is attached to the rotor, a rotating arm is continuously provided below each blade along the outer wall of the transparent case, and a wiper is attached to the rotating arm. Is a device for wiping the outer peripheral surface of the case, depending on this device, compared to the guidepost,
There was also a weighted load such as the operation of the rotating arm, and it was even more apparent that it could not serve as a snow control function. In addition, in the present invention, there are disadvantages such as lack of simplicity as the equipment of a large number of gaze guide signs.

[0005]

As described above, in the prior art, it is difficult to recognize any related technology which is mainly aimed at snow protection or is considered effective. However, it is possible to deal with snow protection by including these related technical means. It is as follows if the subject as a gaze guidance target is calculated | required, and this invention has dealt with this. (1) A large number of installations are required over a wide area of the road, and it is considered that the use of natural power such as wind power is optimal for the snow protection effect of the guidepost of the light device, and it is necessary to use a simple device. (2) The wind power for snow protection is required to operate lightly even under a light wind, and to have a high frequency of snow removal. (3) Since this device is placed in an environment such as receiving the wind pressure of a passing vehicle in addition to natural wind, adaptability of equipment corresponding to the wind direction and the like, easy maintenance and the like are required.

[0006]

SUMMARY OF THE INVENTION The present invention does not take the means of adding a separate device for snow protection to a line-of-sight guidance sample in a conventional manner. This is a conversion of technical means to a system in which the body itself also functions as a conventional reflector.

That is, a plurality of blade pieces are attached to a rotating shaft so as to be rotatable in a horizontal direction, and a retroreflective material for light is provided on both front and back surfaces of the blade pieces in order to use a rotating guide member. It is assumed that both ends of a shaft center passing through the rotating shaft are sandwiched between both ends of a horizontal U-shaped bracket. Further, in this rotating device, a magnet is used at the lower bottom in the vertical rotating shaft, and means for exerting a levitation function based on the repulsion of the magnetic force on the rotating shaft is used to maximize the rotation.

In the present invention, the blade pieces are not fixed to the rotary shaft, but each blade piece is slidable from the upper part of the peripheral surface of the rotary shaft to be detachable. The blade piece and the rotating shaft were formed so that they could be attached.

[Action]

By taking the above measures, the rotating body which also serves as the reflector according to the present invention has a structurally simple and no load such as a snow wiping operation, and has a floating function based on a magnetic force. The frequency of rotation operation for snow protection increases.

[0010] Further, since the blade pieces can be attached to and detached from the rotating shaft and the wind receiver can be turned in the opposite direction, an efficient device can be selected according to the installation location on the road. In addition, this detachment method provides simplicity such as maintenance and replacement.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 and 2, a main body of the present invention is a bracket formed in a horizontal U-shape by passing a shaft core (3) through a rotating shaft (2) having a blade piece (1). The end of the shaft core (3) is sandwiched between both ends of (4) to enable horizontal rotation by wind force.

Three blade pieces (1) are arranged, formed into a curved shape suitable for a wind receiver, and attached to the peripheral surface of a pipe-shaped rotary shaft (2). Attachment is made by a detachable fitting method, and a column of supporting sheaths (7) is provided on the peripheral surface of the rotating shaft (2), and the blade shaft (8) of the blade piece (1) is slid and fixed. The blade piece (1) can reverse the wind receiving surface by inserting the blade shaft (8) in reverse. FIG. 3 shows a comparison between the normal arrangement of the blade piece (1) and the case where the blade piece (1) is inverted.

The blade piece (1) and the rotating shaft (2) are both formed of plastic. Further, a reflective material having retroreflectivity was attached to both the front and back surfaces of the blade piece (1) and the surface of the rotating shaft (2). Instead of this, the reflective material may be molded by a transparent diamond cut.

Next, as shown in FIG. 4, bearings (5) are fitted to both ends of the rotating shaft (2). The bearing (5) used had lubricity, and a low-friction bearing was used in this example. Furthermore, two donut-shaped magnets (6) that can pass through the shaft core (3) are disposed at the bottom of the rotating shaft (2) in contact with the lower surface of the bearing (5) at the lower end by a combination that repels with the same polarity. did. As a result, the upper magnet (6) is in close contact with the lower surface of the bearing (5), the lower magnet (6) is supported by the spacer (10), and the rotating shaft (2) is always in a floating state. The blade piece (1) rotates even by a slight wind pressure. As the magnet (6), an appropriate amount is used by adjusting the quantity or magnetic force according to the total weight of the blade piece (1) and the rotating shaft (2).

The shaft core (3) is made of a rod-shaped brass, and is threaded at both ends. The shaft core (3) passes through the rotating shaft (2) having been assembled as described above, and as shown in FIGS. 1 and 2, the upper end of the rotating shaft (2) is covered with a cylindrical lid (9). At the same time, a spacer (10) is screwed into each end of the shaft core (3), and each end of the spacer (10) is fixed in a through hole (12) provided at both ends of the bracket (4) by a fixing bolt ( It is fixed by 11). At the back of the bracket (4), a through hole (12) for a guardrail support, a ball and the like is provided.

The results of partial observation of the adaptation state on an outdoor road according to the present invention using the sample used in the present embodiment are as follows. 1. Regarding the rotation of the blade piece under the condition of low wind speed, it was confirmed that the blade piece rotated lightly even in an extremely small wind that could be felt on human skin. 2. The result of the comparison of the reflection luminance of the reflector when the blade piece is rotating and when it is stationary shows that the luminance decreases numerically during rotation (about 13
%), But little difference in luminance was observed by comparison with the naked eye, and it was determined that there was no problem with the reflectivity according to the present invention.
