Description

  The present invention relates to a road reflector that is installed in front of an intersection or a curve and can visually recognize the state of a blind spot from the front.

  The road reflector is installed in the vicinity of a sharp curve where the existence of a blind spot due to a house, a fence, etc., and the prospect of poor visibility of a residential area cannot be confirmed.

  Therefore, in general, drivers of automobiles and motorcycles are likely to encounter accidents where the road reflector is installed in the right and left direction and the prospect of the front is bad, so it is safe to pass. We recognize that this is a place where we have to be careful.

  Therefore, by recognizing the existence of this road reflector, the driver of the car or motorcycle recognizes that this place must be taken care of safely, and with this road reflector, the situation in the blind spot direction That is, after confirming the safety of other vehicles, bicycles, pedestrians, etc. from the blind spot direction, enter the intersection or curve with sufficient safety, and encounter accidents. Occurrence is prevented in advance.

  However, when the surroundings of a conventional road reflector become dark at night, not only can the status of the blind spot direction be confirmed on the mirror surface, but the presence of the road reflector itself becomes difficult to recognize. A driver such as a motorcycle may not be able to recognize that this place should be taken care of safely, neglecting the safety check, and possibly causing an accident.

  The present invention has been made in view of the current situation as described above. Even if the surroundings become dark at night, it is ensured that this place is a place where the place must be safely taken care of. An object is to provide a road reflector that can be recognized by a pedestrian or a pedestrian.

  The gist of the present invention will be described with reference to the accompanying drawings.

  In a road reflector that is installed in front of an intersection or curve and can visually recognize the direction of a blind spot from the front, a mirror surface portion 3 formed by attaching a mirror surface forming material 2 to a transparent substrate 1, and the mirror surface portion 3 A light source unit 4 that emits light toward the mirror surface forming material 2, and the mirror surface unit 3 is configured to apply the light irradiated from the light source unit 4 to the thickness of the mirror surface forming material 2 on the transparent substrate 1. The half mirror part 5 set to a thickness that can be transmitted to the transparent substrate 1 side and the whole mirror part 6 set to a thickness that cannot be transmitted are formed, and the shape of the half mirror part 5 is the mirror surface part 3. When the light source unit 4 is turned off, the mirror surface unit 3 becomes a reflecting mirror, and the light source unit 4 is turned on. The light emitted from the light source unit 4 is transmitted through the semi-transparent mirror unit 5. Those of the road reflection mirror, characterized in that arouse characters attention during passage to the mirror portion 3 surface is configured such that the indicator is displayed Te.

  The mirror surface portion 3 is attached to the transparent substrate 1 so that the mirror surface forming material 2 has a thickness capable of transmitting the light irradiated from the light source portion 4, and then the mirror surface forming material 2 is attached. A mask portion is provided at a position on the transparent substrate 1 where the semi-transparent mirror portion 5 is to be formed, then the mirror surface forming material 2 is provided on the transparent substrate 1, and the mirror surface forming material 2 other than the portion provided with the mask portion. Were attached so that the light irradiated from the light source part 4 could not be transmitted, and then the mask part was removed to form the half mirror part 5 and the full mirror part 6.

In addition, even if it is difficult to recognize the presence of the road reflector itself, the mirror surface part may call attention when, for example, “pedestrian attention” or “bicycle attention” passes. Because the indicator lights are displayed, the driver of the car or motorcycle recognizes that this place must be taken care of safely by looking at the characters displayed on the indicator lights. It is possible to enter while paying sufficient attention to the blind spot direction so as not to cause an accident, so that it is possible to prevent the occurrence of accidents that encounters in advance. Periodic road reflection To become.

  In the invention according to claim 2, when the light source part is turned off, the mirror part becomes a reflecting mirror, and when the light source part is turned on, the light irradiated from the light source part is a semi-transparent part. It is possible to easily design a structure that becomes a display lamp that displays characters that pass through the mirror surface and call attention to the surface of the mirror surface. The structure that prevents light from being transmitted to the transparent substrate side has been realized by increasing the thickness of the mirror surface forming material, so that it has excellent durability and good shape of the semi-transparent mirror even when installed in a poor environment such as outdoors. Thus, it is an epoch-making road reflector that is excellent in practicality and productivity.

  An embodiment of the present invention which is considered to be suitable will be briefly described with reference to the drawings showing the operation of the present invention.

  In the present invention, since the entire surface of the mirror surface portion 3 is a mirror surface in a bright situation during the daytime, a blind spot is generated due to a house, a fence or the like, and the prospect is poor, as in a normal road reflector. By installing it in front of a sharp curve where you can not confirm the existence of oncoming street intersections and mountain roads, you can check the situation in the blind spot direction, that is, other vehicles, bicycles, pedestrians etc. approach from the blind spot direction. The mirror surface unit 3 can confirm whether or not it is safe.

  Further, when the light source unit 4 is turned on in the situation where the surroundings are dark at night, the light irradiated from the light source unit 4 is transmitted through the semi-mirror unit 5 to form the semi-mirror unit 5 of the mirror surface unit 3. The mirror portion 3 becomes a display lamp in which the shape of the semi-transparent mirror portion 5 emerges on the surface.

  In the present invention, the shape of the semi-transparent mirror portion 5 is set to a character shape that calls attention to a person who has viewed the mirror surface portion 3 when passing, for example, a character shape such as “pedestrian attention” or “bicycle attention”. Since it is configured, on the surface of the mirror surface portion 3, characters such as this “pedestrian caution” or “bicycle caution” are displayed so as to call a driver or a pedestrian, such as a car or a motorcycle, to be careful. The

  As a result, even if it becomes dark at night and it becomes difficult to recognize the presence of the road reflector, the driver or pedestrian will notice the characters displayed on the mirror surface part 3 and this place can be taken care of safely. This makes it possible for drivers and pedestrians to enter this place with careful attention to the blind spot direction so as not to cause an accident. Even if the effect as a road reflector is not demonstrated at night, it is possible to prevent accidents from occurring at intersections or sharp curves with poor visibility.

  In this way, the present invention is effective as a normal road reflector during the day, and recognizes the driver and pedestrian that this place must be taken care of at night. It is an epoch-making road reflector excellent in practicality that exhibits an effect as an indicator lamp that displays characters that call attention during traffic.

In the same way as conventional road reflectors, it is installed at the intersection of a residential area where the blind spots were caused by houses, fences, etc. and the prospect of the oncoming road on the mountain road could not be confirmed. Thus, it is possible to confirm the situation in the blind spot direction, that is, confirm whether or not other vehicles, bicycles, pedestrians, etc. are approaching from the blind spot direction.

  Even if the surroundings become dark at night and it becomes difficult to recognize the presence of the road reflector 7, the light source unit 4 provided inside the road reflector 7 is automatically turned on and irradiated from the light source unit 4. The light is transmitted through the semi-reflecting mirror part 5, and the part of the specular part 3 where the semi-reflecting part 5 is formed becomes brighter, and the specular part 3 displays the shape of the semi-reflecting mirror part 5 on the surface (floats up). It becomes.

  Specifically, in the case of the present embodiment, as shown in FIG. 2, care should be taken when passing on the surface of the mirror surface 3 to drivers of automobiles, motorcycles, etc., which are “pedestrian caution” and “bicycle caution”. Is displayed in bright white characters, so that even if it becomes dark at night and the road reflector is difficult to recognize, the characters displayed on the mirror surface 3 are displayed on the driver or walking. So that drivers and pedestrians can see this place as a blind spot to prevent accidents. To prevent accidents from occurring at intersections with poor visibility or sharply curved roads even if the effect of the road reflector is not demonstrated at night, with careful attention to direction. Can do.

  In this way, this example demonstrates the effect of a normal road reflector during the day, and at night, to the driver or pedestrian that this place must be safe. It becomes a revolutionary road reflector excellent in practicality that exhibits the effect as an indicator lamp that displays characters that call attention during traffic for recognition.

  Note that the present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
