Description of the Related Art In general, a line-of-sight guidance sign is installed on a road, and a sign composed of a retroreflector is formed at a top end of a support column toward a driver of a vehicle. As a result, the self-cleaning line-of-sight guide sign utilizing wind power protruded from the center of the sign surface as described in Japanese Utility Model Publication No. 55-27885. A plurality of rotating blades rotating by a horizontal axis are supported, the rotating blades are rotated by wind power, and the wiping element attached to the rotating blades is slid on the surface of the sign body, so that dust and dirt attached to the sign body surface Is disclosed.

を低下させている。However, since the self-cleaning line-of-sight guidance sign by wind power has a blade piece wiper attached to the front surface of the sign, the surface of the sign is obstructed by these and the reflection area is reduced. In addition, the rotating shaft and the wiper of the blade piece break down and cannot be driven, and must be constantly maintained. In addition, since the wiper constantly rubs the sign surface, the mark is scratched by dust and dust, thereby reducing the retroreflective function.

低減を来さざるを得ない。Further, in order to prevent the above-mentioned sign from being stained, a transparent plastic molded article having a front surface having an inclined angle is coated and mounted on the sign so that the self-cleaning action by rainwater can be achieved. However, when the transparent molding is coated on the sign, the light from the car illuminates the molded body and is first reflected on the inclined surface, and a part of the light reaches the sign and is retroreflected. The retroreflective effect is reduced. Furthermore,
During use, the molded product is damaged or its surface is killed, and its function must be reduced.

である。Means for Solving the Problems In order to achieve the above object, the present invention is devised as follows. In other words, the gaze guidance sign according to the present invention is that the sign surface to be visually recognized by the driver is always kept in a dirt-reduced state, so that the self-cleaning action by rain can be maximized, and the appearance and structure are improved. A shape that does not cause a problem may be devised.
Therefore, by making the upper part of the frame that supports the signage into an inclined surface shape that flows in one direction toward the signage surface, rainwater can be more easily received on the inclined surface, and the falling water flows down the signage surface and falls. They try to wash off the kimono.

A vertical groove may be formed as a water channel leading to the marking surface. Further, if the head of the frame is formed in a round shape along the side surface of the sign surface, the flow efficiency to the sign surface is reduced, so that the inclined surface above the frame body is not a convex surface in the width direction of the sign surface. , Rainwater can be caught efficiently.

A hydrophilic coating is formed. By making the surface hydrophilic, contaminants on the surface are less likely to adhere, and even if it adheres, a function of being easily washed by rainwater may be provided.

FIG. 1 is a perspective view showing an embodiment of a line-of-sight guidance sign. In the figure, in a structure in which a sign 3 is fixed to a top end of a support 1 by a frame 2, FIG. 2 shows an example in which a groove 4 is cut in the inclined surface of FIG. 1, and FIG. 3 shows a shape of a double-sided line-of-sight guidance sign, In FIG. 4, the inclined portion is flat in the width direction and forms a horizontal plane.

させることにより視線誘導を行うようになされている。First, in the single-sided line-of-sight guidance sign of FIG. 1, a frame 2 made of an aluminum alloy or the like is attached to the top end of a column 1, and the frame 2 has a retroreflective function toward a traveling vehicle. The sign surface 3 is attached, and the sign surface is brightly shined by receiving light from a headlight of a car and performing retroreflection. The driver can visually recognize the sign body 3 to perform gaze guidance.

なされたものである。The sign 3 made of a retroreflector is made of a translucent synthetic resin plate made of polycarbonate, acrylic resin or the like, and has a diamond cut back surface. When light is applied to the front surface of the sign 3, the light is reflected by a diamond-cut portion on the back surface, and the light is returned in the irradiated direction.

面の汚れを洗い流してくれる自浄作用が働いてくる。Normally, the frame 2 supports and protects the sign 3 on the column 1. The head of the frame has a rounded shape with a minimum required swelling. It has a shape that flows on both sides of the sign surface and does not pass through the front of the sign body. Further, the frame whose shape largely covers the front of the sign surface is not structured to further catch rainwater. In view of such a shape, an inclined surface through which the frame body can flow toward the sign surface as shown in FIG. 1 is provided, and the shape is such that a step between the sign surface and the frame member is eliminated. Therefore, the rainwater that has fallen on the inclined surface flows down along the sign surface, and at that time, a self-cleaning action works to wash off dirt on the sign surface.

来ない。However, since the frame body is inclined in the plane direction of the sign body and curved down in the side direction, the rainwater falling on the frame body flows down along the inclination angle of the frame body. The surface is not wet. That is, if the vertical angle with the marking surface is 45 degrees, if the curved contact angle of the frame body is less than 45 degrees, it will flow down to the marking surface, but if the contact angle is 45 degrees or more, the frame will not flow down the marking surface without falling off the marking surface. It flows down the side of the body. In this case, the amount of wetting the marking surface is theoretically about 71% with respect to the projected area of the inclined surface. In addition, the greater the vertical angle with the marking surface, the more rainwater can be received,
The height of the sign body becomes large, causing a structural problem. If the vertical angle is small, the amount of water droplets flowing down the sign surface cannot be obtained.
【0015】図2は枠体の傾斜面に降った雨水をより効

い。FIG. 2 shows a vertical groove formed so that rainwater that has fallen on the inclined surface of the frame body can flow down to the sign surface more efficiently.
The grooves are provided with a good drainage and a shape in which dust is less likely to accumulate. Further, the groove may be formed in a mountain shape without using the groove, and the groove and the mountain may be used in combination.

標示体面に流し出させるよう配慮されている。FIG. 3 shows a double-sided line-of-sight guide sign provided with retroreflective plates on both sides, which plays a role of guiding the line of sight of vehicles passing alternately, and is installed mainly at a curve point. This frame body also has an inclination angle at which rainwater flows down on both sides by protruding the upper part of the frame body with the front and back sign bodies sandwiched in the same manner as in FIGS. Also, FIG. 4 shows that the inclined portion of the frame body head is approximately flat in the width direction or the central portion forms a concave surface, and a raised frame that can stop water around the inclined excluding one side flowing down is provided, and the inclined frame descends on the inclined surface. Care is taken to allow almost all of the rainwater to flow to the sign body surface.

とが出来る。Although the frame is composited in such a manner as to protect the sign, the frame may be formed as an integrally molded article of a light-transmitting synthetic resin such as polycarbonate or acrylic resin. Since the inclined surface and the sign are integrally formed, there is no seam between them, and the raindrops flow smoothly without stagnation, so that the self-cleaning action can be further enhanced.

ようとするものである。The self-cleaning gaze guide described in Japanese Patent Application Laid-Open No. 10-102441 is applied to the present invention, and an undercoat layer containing a photopolymerization initiator is provided on the sign surface. By forming the hydrophilic monomer film, the surface is made hydrophilic by the action of ultraviolet light, and an effect of washing contaminants attached to the surface due to rainfall or the like is produced. That is, since a hydrophilic coating made of a graft polymer film is provided on the surface of the sign, even if dust or vehicle exhaust gas adheres to the surface of the sign and becomes dirty, rainwater easily flows down to the surface of the sign. Therefore, the adhered contaminants are removed each time and are difficult to deposit, and the performance of the reflector is maintained in a good state for a long time.

きるので維持管理を必要としない。According to the present invention, since the gaze guidance sign is installed on the side edge of the roadway or the median strip, etc., it is an important facility that receives the light of the night car and retroreflects to guide the gaze. The countermeasures have been taken so that they are not contaminated by dust and dirt and do not lower the visibility.The shape of the frame head of the sign constituting the reflective surface has an inclined surface of less than 80 degrees to the vertical angle of the sign body. It is easy to receive rainwater by making the surface a groove or mountain for water introduction, or by making it approximately flat in the width direction or an inclined surface with a concave surface formed in the center to make it easier to catch rainwater more efficiently. Consideration is given to increasing the amount of rainwater flowing down the surface of the sign, thereby increasing the self-cleaning action of the rainwater. As a result, the rainwater directly hits the sign surface in the past, but the present invention has an effect that the rainwater always flows down the sign body to wash away dirt and the like. Further, since the shape of the present invention does not include a drive unit, there is no function stop due to a failure, and breakage or damage can be avoided, so that no maintenance is required.

大きなものとなる。On the other hand, by not forming a composite structure in which the sign is fitted in the frame, but forming an integral structure of the sign having the shape of the frame, there is no seam and the self-cleaning action becomes more effective.

出来る。Further, by applying a photopolymerization initiator to the surface of the sign body, the surface activated by ultraviolet rays keeps hydrophilicity, thereby making it difficult for dust and exhaust gas to adhere to the surface and effecting the passage of more rainwater. It is possible to cause the attached matter to flow out.
