JPH11237853A - Luminous adapter for line of sight guide symbol - Google Patents

Abstract

PROBLEM TO BE SOLVED: To contribute an adapter to traffic safety and to prevent the waste of an existent reflection type guide symbol by improving the poor visibility in fog, snowing or heavy rainfall of the existent reflection type guide symbol. SOLUTION: The luminous adapter is fixed by using a metal band 4 for an existent reflection type guide symbol 20 later and with a solar battery 5 as a power source, an LED 6 is emitted by itself at night or when the light of head lights is received so that improvement in visibility is attained. Thus, sight-line guidance is enabled by the light of a light emitter even in fog, snowing or heavy rainfall which is a weak point for the reflection type guide symbol, and the adapter can be contributed to improvement in traffic safety. Besides, since this luminous adapter is just attached as an adapter to the existent reflection type guide symbol, it is not necessary to replace the existent reflection type guide symbol with any expensive luminous one, facility costs are reduced and the waste of the reflection type guide symbol is prevented as well.

Further, in the invention according to claim 3,
According to the first aspect of the present invention, a light receiving sensor is inserted into a power supply circuit of the light emitting body, and when light of a headlight of an automobile or the like irradiates the light receiving sensor, the power supply circuit of the light emitting body is closed and the light emitting body is closed. In addition to the light emission, when the irradiation by the headlight is completed or when a certain time has elapsed after the light emission, the power supply circuit is closed to stop the light emission of the light emitter.

Further, in the invention according to claim 4,
The invention according to claim 1 is characterized in that the light emitter emits light only when both the day and night sensor and the light receiving sensor are closed.

Further, in the invention according to claim 5,
In one of the inventions according to any one of claims 1 to 4, the luminous body is attached to both the front side and the back side of the apparatus main body, so that both sides emit light by themselves. Is what you do.

[0011]

[Function] The self-luminous adapter is used for the existing reflective guidepost,
Attach using mounting means. This self-luminous adapter can be used at night or (and) depending on the electromotive force generated by the solar cell.
When receiving the light from the headlights of the car, the power supply circuit is closed and the luminous body emits light. In addition to the reflected light, self-emission enhances visibility and contributes to traffic safety. Do not waste.

[0012]

[Embodiment 1] This embodiment will be described in detail with reference to FIGS. In FIG.
1 has a circular mounting portion 2 formed at the center, which can be externally mounted on the existing reflective guidepost from behind or from above, and is tightened by being wound around the reflective guidepost by four hinges 3. Main body 1 provided with a metal band 4 for performing the operation, 5 is a solar cell (solar unit) mounted on the upper surface of the main body 1, 6 is an upper left and right two places, and a lower
LED as an example of a luminous body incorporated in three places,
All facing the front.

Reference numerals 7, 7a and 7b denote anti-theft lock keys for stopping the tip of the metal band 4 in the main body 1. In FIG. 3, 8 denotes a control circuit (control board), 9 denotes a battery, and 10 denotes a day / night detection sensor. , 11 is a light receiving sensor, which sends a signal to the control circuit 8 when detecting light from the headlights of the vehicle.

As shown in FIG. 2 and FIG. 3, the self-luminous adapter according to the present invention is mounted on the reflective guide 20 while expanding the metal band 4 with the hinges 3. Tighten and lock using lock keys 7, 7a, 7b to prevent theft and the like. This fixing means may use other conventional fixing means. However, it must not be easily removed and stolen. The position and number of the LEDs 6 can be freely set. When the self-luminous adapter is mounted on the reflective guidepost 20 in this manner, the self-luminous adapter is attached to the reflector 2 as shown in FIGS.
The LED 6 is arranged at four places around the solar cell 1, and the solar cell 5 is located above the guidance mark 20, so that it becomes easy to receive sunlight.

FIGS. 2 and 3 show examples in which a self-luminous adapter is attached to an existing reflective guidepost. When a new reflective guidepost 20 is installed, the self-luminous adapter according to the present invention is used. You may make it attach. The reflection type guide mark 20 of the embodiment has a rotating blade 22 attached thereto.
Needless to say, it can be attached to a type having no rotary blade 22.

The self-luminous adapter has the following functions. 1. The solar cell receives the sunlight and generates an electromotive force, and the electromotive force is charged in the battery 9. Then, the day / night detection sensor 10 detects the ambient brightness, and when the brightness becomes lower than a certain value, the control circuit 8 closes the power supply circuit for the LED 6. Due to this closing, L
Power is supplied to the ED 6, and the LED 6 emits light (claims 1 and 2).

2. When the light receiving sensor 11 receives the light of the headlights of the automobile, the control circuit 8 closes the power supply circuit of the LED 6 and emits light from the LED 6. This light emission is performed for a preset time while detecting the light of the headlight or after detecting the light of the headlight (claims 1 and 3). 3. Only when both the day / night detection sensor 10 and the light receiving sensor 11 are activated, the control circuit 8 closes the power supply circuit and
The ED 6 emits light (claims 1 and 4).

[0018]

Embodiment 2 In this embodiment, the LED 6 is attached to both sides (front and rear) so as to be adapted to a double-sided reflection type guide mark, and the LED 6 is positioned symmetrically with respect to FIGS. And the same functions (actions) as those of the first to third actions of the first embodiment (claims 1 and 5).

[0019]

The self-luminous adapter according to the present invention has the following effects because it can be used by attaching it to a reflective guidepost. 1. Even in fog, snowfall, and heavy rain, which are the drawbacks of the reflective guidepost, gaze guidance is possible with the light of the illuminant, which can contribute to improving traffic safety (claims 1 to 5).

2. Since it is only attached as an adapter to the existing reflective guidepost, there is no need to replace the existing reflective guidepost with an expensive spontaneous one, and the equipment cost is reduced, and there is no waste in disposing of the reflective guidepost. (Claims 1 to 5). 3. The self-luminous adapter uses a metal band so that there is no bulge on both sides, so that the wind on both sides is well ventilated and does not hinder its rotation when equipped with rotating blades. 6).
