Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to road gaze signs such as snow poles and delineators installed on roads in snowfall areas.

[0002]

[Prior Art]

 Conventionally, road line-of-sight guidance signs such as snow poles and delineators are attached by winding a reflective tape around the pillar for night visibility, or by attaching a disk-shaped reflector to the pillar. The light from the lights is reflected by these to guide the eyes of the vehicle driver.

[0003]

[Problems to be solved by the device]

 However, in such conventional road gaze signs, only the reflective tape is attached to the pillar or the disc-shaped reflector is attached, so that the reflective tape or the reflective surface of the reflector is covered during snowfall. Snow was likely to adhere to the snow, and the effect of gaze guidance was significantly impaired by the snow, which could cause a traffic accident in some cases.

An object of the present invention is to provide a road gaze guidance sign for preventing snow accretion that solves the above conventional problems.

[0005]

[Means for Solving the Problems]

 The present invention basically prevents the snow from accumulating by making the reflecting surface of the reflector attached to the column a slanted downwardly inclined surface. That is, in the road gaze guidance sign of the present invention, a vertical cylindrical reflector is externally attached to at least the upper end of the column, and the outer peripheral surface of the reflector bulges in the radial direction. The outer diameter is gradually reduced from the large-diameter portion to the lower end, and the outer peripheral surface from the large-diameter portion to the lower side is formed as a reflecting surface that is obliquely downward.

Further, the upper part of the reflector at the upper end of the support column is supported on the top of the support via the rotating shaft part, the rotating shaft part is covered with the reflector, and the rotary blade is fixed to the outside of the reflector. When the root receives wind pressure, the reflector can swing and rotate around the rotating shaft.

【Example】

 Hereinafter, the present invention will be described with reference to the drawings. In the drawing, 1 is a column, which is made of metal, synthetic resin, or the like, and has a circular cross section, a square shape, or the like. The support 1 may be a single pipe or a rod-shaped body, or a plurality of pipes or rod-shaped bodies may be fixedly added, or may be extended and contracted to have a predetermined length. In order to provide night visibility to the side surface of the pillar 1, a reflective tape 11 is wound and attached at appropriate intervals in the length direction. This pillar 1 is generally planted on the road shoulder and is used as a road marking.

Reference numeral 2 denotes a reflector, which has a vertical cylindrical shape made of synthetic resin, metal, or the like. The shape of the reflector 2 is basically such that the outer peripheral surface on the upper end side of the tubular body is bulged in the radial direction, and the outer diameter is gradually reduced from the bulging large diameter portion 21 toward the lower end of the tubular body. The lower side from the large-diameter portion 21 has an inverted truncated cone shape or an inverted truncated pyramid shape. That is, the outer peripheral surface on the lower side from the large-diameter portion 21 is formed as an inclined surface that is inclined downward. A reflecting sheet, a synthetic resin prism reflecting plate, or other reflecting material is attached to the inclined surface to form a reflecting surface 22. The reflecting surface 22 is formed so as to form an angle of 5 to 25 degrees with the vertical direction from the viewpoint of the reflectivity and the prevention of snow accretion.

It is preferable that the outer peripheral surface on the upper side of the large-diameter portion 21 is an inclined surface that is obliquely upward as shown in FIG. 3, for example, so that snow is less likely to be accumulated, and a reflective material such as a reflective sheet or a reflective plate is attached. It is preferable that the visibility is improved at night. The outer peripheral surfaces of the upper and lower end portions of the reflector 2 are generally arranged to be substantially parallel to the side surfaces of the column 1 as shown in FIG.

The reflector 2 is externally attached to the upper end or the upper end of the column 1 at one to a plurality of positions. The reflector 2 attached to the upper end of the pillar 1 is in the shape of a vertical cylinder with the upper part closed, and is fixedly or rotatably attached to the upper end of the pillar 1 as described later. The reflector 2 attached to a portion other than the upper end of the column 1 has a vertical cylindrical shape with both upper and lower portions opened, and is inserted into the column 1 as shown in FIG. 1, and the upper and lower end portions thereof are fasteners 5 such as bis and rivets. It is fixed to the column 1.

In the case of FIGS. 1 to 3, for example, the reflector 2 on the upper end of the column 1 is covered on the upper end of the column 1, the upper part of the reflector 2 is on the top of the column 1, and the lower end of the reflector 2 is. The parts are fixedly attached to the side surfaces of the column 1 by fasteners 5 such as screws and rivets.

In addition, in the case of FIGS. 4 to 6, as shown in FIG. 5, the upper end of the column 1 is covered with the reflector 2, and as shown in FIG. 6, the top of the column 1 and the upper part of the reflector 2 are covered by the rotating shaft 3. The reflector 2 is connected and supported so as to be swingable and rotatable around the rotating shaft 3. In this case, the rotary shaft portion 3 is covered with the reflector 2 to prevent snow from landing on the rotary shaft portion 3. Further, as shown in FIGS. 4 to 5, a rotary vane 4 is fixed to the outside of the reflector 2 so that the rotary vane 4 receives wind pressure and swings and rotates the reflector 2 around the rotary shaft portion 3. Has been done.

As shown in FIG. 6, the rotary shaft portion 3 holds a rotary shaft 31 that is provided inwardly protruding from the upper portion of the reflector 2, a receiving portion 32 fixed to the top of the column 1, and a rotary shaft 31. And a holding portion 33 that operates. The tip of the lower end of the rotary shaft 31 is placed in the recess of the upper surface of the receiving portion 32, and the reflector 2 is rotatably and rotatably supported. The rotary shaft 31 and the receiving portion 32 may be formed by appropriate bolts and nuts as shown in FIG.

In order to prevent the rotating shaft 31 and the receiving portion 32 from being separated from each other due to wind pressure or the like, the rotating shaft 31 is inserted and held by a holding portion 33 fixed to the top of the column 1. The holding portion 33 is made of a spring steel plate piece or wire, and the lower end bent into a substantially U-shape as shown in FIG. 6 is fixed to the top of the column 1 together with the receiving portion 32, and the rotary shaft 31 is inserted through the insertion hole of the upper end. Has been done. In order to prevent the rotating shaft 31 from coming off from the holding portion 33, the holding portion 33 is engaged with the neck portion provided on the rotating shaft 31, or the lower portion of the rotating shaft 31 that penetrates the holding portion 33. Is provided with a protrusion for retaining.

As shown in FIG. 5, the rotary vane 4 has an arm 41 of a plate piece or wire made of spring steel, piano wire, a weight 42 attached to both ends of the arm 41, and an arm 41 on both ends of the arm 41. It is formed by a wind pan 43 attached along the boom 41. As shown in FIG. 6, a central mounting portion of the arm 41 of the rotary blade 4 is fixed to the reflector 2 by a rotary shaft 31 above the reflector 2, and balance is maintained by weights 42 at both ends. The wind pan 43 may be formed in a shape such as a flat plate having a bent tip as shown in FIG. 4 so as to easily receive the wind, and a reflector may be appropriately attached to the wind pan 43.

When the rotary blade 4 receives wind pressure on the wind pan 43, the rotary blade 4 swings and rotates about the rotary shaft portion 3 while keeping the balance, and the reflector 2 with the rotary blade 4 fixed is simultaneously swung and rotated. It is designed to let you. The structure of the rotary blades 4 is not limited to the above, as long as the reflector 2 is swung and rotated about the rotation shaft portion 3 by wind pressure.

[Effect of the device]

 As described above in detail, in the road gaze guidance sign of the present invention, the reflector has a vertical cylindrical shape, the outer peripheral surface on the upper end side is bulged in the radial direction, and the outer diameter is increased from the large bulging diameter portion toward the lower end. Since it is made smaller gradually and the outer peripheral surface from the large diameter part to the lower side is a diagonally downward facing reflection surface, it is difficult for snow to adhere to the reflection surface during snowfall and night visibility can be maintained in a good state, preventing traffic accidents. To help. Moreover, even when it is not snowing, dirt is not easily attached to the reflecting surface and the reflecting area can be widened, so that the reflecting effect can be enhanced.

In addition, the upper part of the reflector at the upper end of the support is supported by the top of the support via the rotary shaft, and the rotary vanes fixed to the outside of the reflector receive wind pressure to cause the reflector to swing around the rotary shaft. Since it is movable and rotatable, the reflector sways and rotates due to wind pressure during snowfall, making it difficult for snow to adhere to the reflecting surface and providing visual stimulus to the vehicle driver to further enhance the line-of-sight guidance effect. Can be large. Since the rotating shaft portion is covered with the reflector, snow does not adhere to the rotating shaft portion, the reflector smoothly swings and rotates, and the above effect can be further promoted.
