Description

The present invention relates to a pole with a road reflector. More specifically, the present invention relates to a pole with a road reflector that can prevent an accident at an L-junction, a T-junction, or the like.

Conventionally, poles with road reflectors are used at L-junctions, T-junctions and sharp curves (see, for example, Patent Document 1).
In general, many drivers feel that the image reflected in the mirror is unreliable and must be visually checked. This is because there is an image that spiritual power dwells in the mirror. Especially around the Bon Festival in the summer, there is a test of courage, and interest in scary stories increases. Due to the influence of those memories, it is generally believed that psychic phenomena occur in mirrors.

If psychological factors cause anxiety about the reflected image of the mirror, it can be resolved by prayer. Prayers for traffic safety are held at temples and shrines for drivers.
Disney's Snow White is known as a story that reflects the unreal world in a mirror due to psychological factors. In this story, when the princess asks the magic mirror who is the most beautiful in the country, the mirror answers that it is Snow White who lives in a dwarf's house deep in the forest (non-patented). Reference 1).

A magic mirror is known as a mirror that reflects an image other than the image incident on the mirror. A magic mirror is a mirror in which light and shade appear in the reflected light. This shading occurs when the surface of a mirror cast in bronze is polished, and the polishing pressure causes the mirror surface to undulate. Therefore, the thickness of the mirror is limited to a certain degree. As a magic mirror , for example, a Kakure Kirishitan mirror is known.

If the reliability of the reflecting mirror is to be improved by physical factors, it is effective to increase the reflectance of light and to make the perspective match as much as possible compared to the real world. A low-priced curved mirror with an inappropriate sense of perspective has a large refraction on the outer peripheral side of the mirror surface, making it appear as if a car at a constant speed is suddenly accelerating, and is therefore not highly reliable.
In some cases, blurring is preferred for makeup. This is because when the dullness of the skin stands out, when you wake up in the morning and stand in front of the bathroom mirror, you will feel disillusioned and start the day with a dark feeling. For example, if the middle part of the nose is flattened or if the metal on the teeth stands out, disillusionment will occur. The present applicant has made an invention focusing on the importance of the central part of the nose dorsum (see Patent Document 2).

As poles with road reflectors that eliminate anxiety due to physical factors, there are products that meet the installation standards and are used on public roads. For example, a polished surface of SUS304, which is a stainless steel material, is used. This is called a surface mirror.

However, in the conventional pole with a road reflector, the visibility of the road reflector is poor at night, and it cannot be said that sufficient safety is ensured.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a pole with a road reflector that can prevent accidents at the intersection of L-junctions and T-junctions.

As a result of intensive research on such problems, the inventors of the present invention have found that it is possible to prevent accidents at L-junctions, T-junctions, etc. by providing light-emitting means on poles with road reflectors. I found that I could do it, and came to complete the present invention.

BEST MODE FOR CARRYING OUT THE INVENTION The best mode for carrying out the present invention will be described below with reference to the drawings.

FIG. 1 is an explanatory diagram showing an example of a usage pattern of the pole with a road reflecting mirror of the present invention. The road reflector-equipped pole 1 of this mode of use is provided on the out-corner side of the L-shaped road, more specifically outside the corner of the L-shaped road. Such a location may be, for example, a bush area outside the curb of a pavement. A pole 1 with a road reflecting mirror has a reflecting mirror 3 attached to the tip of a pole 2, and the reflecting mirror 3 allows visual recognition of the road on the bend side regardless of which end of the L-shape an automobile enters. It is oriented so that Since the wall W is provided on the inner corner side of the paved road, the driver of the car A cannot directly visually confirm the pedestrian P.

The driver of the car A can avoid contact between the car A and the pedestrian P by keeping a close eye on the reflector during the day. As can be seen from FIG. 1, there is a possibility that a pedestrian will be caught in the car when it turns right, so it is effective to visually confirm the destination using the reflecting mirror 3 . It is also effective to sound the horn of the car A. On the other hand, at night, it becomes difficult to visually confirm the destination using the reflector. Also, sounding the alarm late at night disturbs the residents' sleep. As a means for solving this problem, the pole 1 with a road reflecting mirror of this form of use is provided with a light emitting means 6 .

FIG. 2 is an explanatory view showing the first embodiment of the pole with a road reflecting mirror of the present invention. This pole 1 with a road reflecting mirror has a cylindrical metal pole 2 and a reflecting mirror 3 provided on the tip side of the pole 2 for visually recognizing a visual area. The reflecting mirror 3 is composed of a disc mirror 31 and a holding plate 32 for holding the disc mirror 31. The holding plate 32 is provided with a flange portion 32a on its upper side. The collar portion 32a functions as a rainproof and sunscreen.

The pole 2 is provided with two moving object detection sensors 4A and 4B for detecting the approach of automobiles, motorcycles, bicycles, pedestrians and other moving objects, and the two moving object detection sensors 4A and 4B. A decision circuit 5 for inputting signals from and deciding whether or not a moving object is approaching from a plurality of directions, and the decision circuit 5 determines that a moving object is approaching from a plurality of directions. Light-emitting means 6 are provided which are driven in the case.

The light emitting means 6 has a rotating light 61 that emits LED light and a battery 62 for driving the rotating light 61 . As the rotating light 61, for example, Patlite (registered trademark) can be used. For example, red, green, blue, and white can be used as the types of colors of LED light emission. An incandescent lamp or other light-emitting lamp may be used instead of the LED lamp.

By the way, an accessory with a moving object detection sensor is known as a device for ensuring the walking safety of hearing-impaired persons (see Patent Document 3). This document discloses an invention in which a hearing-impaired person is notified by a light-emitting means when a moving object approaches. More specifically, a pendant for the hearing impaired is disclosed that indicates the approach of an automobile with an LED lamp. The structure used for this pendant is used for the pole with a road reflecting mirror of this embodiment.

FIG. 3 is an explanatory diagram showing the configuration of the device provided on the pole in FIG. The approach of the automobile A is detected by the moving object detection sensor 4A. On the other hand, the approach of the pedestrian P is detected by the moving object detection sensor 4B. Output signals from the moving object detection sensors 4A and 4B are input to the determination circuit 5. FIG. The determination circuit 5 determines that the signals from both sensors 4A and 4B are High signals or Low signals with thresholds as boundaries. By this binarization, the light emitting means 6 is lit or extinguished. In this embodiment, since the output signals from the moving object detection sensors 4A and 4B are High signals, the determination circuit 5 determines that the two moving objects are approaching the reflecting pole 1, and the light emitting means 6 is activated. driven .

FIG. 4 shows the configuration of the moving object detection sensor 4A. The moving object detection sensor 4A includes a Doppler sensor 41 for detecting the approach of a moving object such as an automobile, an amplifier 42 for amplifying the signal from the Doppler sensor 41, and the presence or absence of the moving object based on the signal from the amplifier 42. and a detection circuit 43 for The moving object detection sensor 4A also has a control circuit 44 that receives a signal from the detection circuit 43 and transmits a control signal to the oscillator 411 . A moving object detection sensor 4B (shown in FIG. 3) has the same configuration.

The Doppler sensor 41 has an oscillator 411 , a transmitting/receiving antenna 412 and a mixer 413 . Oscillator 411 transmits a signal of a predetermined frequency according to a signal from control circuit 44 . The oscillator 411 includes an amplifier, which amplifies the oscillated signal with a predetermined amplification factor. A transmitting/receiving antenna 412 transmits the signal from the oscillator 411 via a circulator. An electromagnetic wave transmitted from the transmitting/receiving antenna 412 is reflected by a moving object such as an automobile or a pedestrian, and received by the transmitting/receiving antenna 412 . Mixer 413 receives the signal from transmission/reception antenna 412 via the circulator, multiplies this signal by the signal from oscillator 411 , and outputs the signal to amplifier 42 .

The detection circuit 43 detects the presence or absence of a moving object based on the output signal of the amplifier 42 . The detection circuit 43 has a detection circuit that rectifies the signal from the amplifier 42 and converts it into a DC signal. The detection circuit 43 then transmits to the control circuit 44 a DC voltage corresponding to the intensity of the electromagnetic wave reflected by the moving object.
When the detection circuit 43 determines that there is a moving object, the control circuit 44 transmits a voltage to the light emitting means to light the revolving lamp 61 (shown in FIG. 2). In the case of the present invention, the rotating light 61 is set to light up when the moving object approaches a certain range.

According to the road reflector-equipped pole 1 of the first embodiment described above, the moving object detection sensors 4A and 4B for detecting that a moving object is approaching and the signals from the moving object detection sensors 4A and 4B are input. A determination circuit 5 for determining whether or not a moving object is approaching from two directions, and is driven when the determination circuit 5 determines that a moving object is approaching from two directions. Since the light emitting means 10 is provided, when there is a pedestrian P walking at a position that cannot be visually recognized from the car A at the intersection of the L-shaped road, the light emitting means 10 informs the driver of the car A of the presence of the pedestrian P. can let you know. This is particularly effective during nighttime hours when visibility is poor, and can prevent accidents at the head of an L-junction. In addition, since there is a large percentage of hearing impaired people in an aging society, it is effective in preventing traffic accidents.

FIG. 5 is an explanatory view showing another example of usage of the pole with a road reflector of the present invention. The road reflector-equipped pole 1A of this mode of use is provided at the intersection of a T-junction, more specifically outside the T-shaped paved road. A pole 1 with a road reflecting mirror has two reflecting mirrors 3 with different directions attached to the tip of a pole 2, and each reflecting mirror 3 can visually recognize the road on the right-turn side or left-turn side of a T-shape. It is directed in the direction that it can be. Since the wall W is provided on the inside corner side of the paved road, the driver of the automobile A cannot directly visually confirm the pedestrian P on the right turn side. Similarly, even if the pedestrian P is on the left turn side, the pedestrian P cannot be visually confirmed directly.

FIG. 6 is an explanatory diagram showing a second embodiment of the pole with a road reflecting mirror of the present invention. Unlike the road reflector-equipped pole 1 of the first embodiment, the road reflector-equipped pole 1A is provided with one reflector 3 at the tip of the pole 2 in the first embodiment. The configuration differs in that two reflecting mirrors 3 are provided at the tip of the pole 2 . In addition, although two moving object detection sensors 4A, 4B are provided in the first embodiment, this second embodiment differs in that three moving object detection sensors 4A, 4B, 4C are provided. . The configuration of the moving object detection sensor 4C is similar to that of the moving object detection sensors 4A and 4B.

FIG. 7 is an explanatory diagram showing the configuration of the device provided on the pole in FIG. The approach of the automobile A is detected by the moving object detection sensor 4A. On the other hand, the approach of the pedestrian P is detected by the moving object detection sensor 4B. The moving object detection sensor 4C does not detect any moving object. Output signals from the moving object detection sensors 4A, 4B and 4C are input to the determination circuit 5. FIG. Among the signals from the moving object detection sensors 4A, 4B and 4C, the signals from the sensors 4A and 4B are High signals, and the signals from the sensor 4C are Low signals. In this case, the judgment circuit 5 judges that two moving objects traveling along different sides of the T-junction are approaching the reflecting pole 1, and the light emitting means 6 is driven. The same applies when the moving object detection sensors 4A and 4C are High signals. However, when the moving object detection sensors 4B and 4C are High signals, the light emitting means 6 is not driven because the two moving objects face each other on the straight road.

Although the present invention has been described above, it goes without saying that the present invention is not limited to the above-described embodiments, and that various modifications are possible without departing from the essence of the present invention.

In the above-described embodiment, an example in which the ordinary reflecting mirror 3 is provided on the upper end side of the straight pole 2 has been described. 3A may be used, and a rotating mechanism 7 for swinging the reflecting mirror 3A may be provided above the pole 2 so that the reflecting surface of the reflecting mirror 3 can face the sky . With this configuration, solar charging is possible, so there is no need to replace the battery.

In addition, in the above-described embodiment, a pole with a road reflecting mirror provided at an intersection of an L-junction and a T-junction has been described. Alternatively, it may be provided at a multi-way intersection.

INDUSTRIAL APPLICABILITY The present invention can be used for poles with road reflectors. For example, it can be used for L-junctions, T-junctions or curves with no visibility. It is particularly effective when it is difficult to secure visibility such as at night, in rainy weather, or when fog occurs.
