Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a method for arranging a vehicle on a road,
The present invention relates to a delineator that guides the course of a vehicle.

[0002]

2. Description of the Related Art Conventionally, as a delineator that is arranged on a road and guides the course of a vehicle, a delineator having a reflecting surface that reflects headlights of a traveling vehicle, a light bulb that emits light toward the vehicle, and the like are known. A light source equipped with a light source is known.

[0003]

According to the delineator provided with the reflecting surface, in bad weather such as dense fog or heavy rain, the headlight emitted from the vehicle is blocked by fog or rain and reaches the reflecting surface. Since the amount of light to be emitted is small, retroreflection is weakened, and it is difficult for the driver to recognize it.

On the other hand, according to the delineator provided with the light source, the light is emitted almost only in the front direction of the light emitting surface, so that the angle visible to the driver is limited to a narrow range with respect to the perpendicular of the light emitting surface. Was not so good.

[0005] Therefore, an object of the present invention is to eliminate the drawbacks of the conventional delineator and to provide a delineator with excellent visibility.

[0006]

According to the present invention, there is provided a delineator having a tubular main body, a reflector fixed to an upper portion of the main body and having a reflective surface on a front surface, and a power supply section. In, a plurality of light emitting diodes mounted with a light emitting surface inclined with respect to the reflective surface are arranged at predetermined intervals,
The power supply unit is connected to the plurality of light emitting diodes via a conductive wire.

Since a plurality of light emitting diodes are arranged in a predetermined arrangement on the reflecting surface of the delineator, retroreflection of the reflecting surface and light emission of the light emitting diode can be used together to improve visibility, and Even if the number of light emitting diodes is reduced, sufficient light quantity can be obtained,
The maximum effect can be obtained at low cost.

Further, since the light emitting diode is mounted with the light emitting surface inclined with respect to the reflection surface, the light axis of the light emission is inclined from the front direction of the reflection surface and spreads over a wide angle region. Therefore, it is possible to recognize even from a position shifted from the front direction of the reflection surface.

Further, by mounting the main body on the tip of the bar, it can be easily attached to any bar. Then, it can be easily installed simply by placing it at an arbitrary place integrally with the bar.

The power supply unit may include a battery for causing the light emitting diode to emit light. In this case, the operation of adjusting the power supply becomes unnecessary, and the labor for installation can be reduced.

The inner diameter of the cylindrical main body may be adapted to the outer diameter of the guardrail support. In this case, since a guardrail support provided at the installation location can be used, a bar for installation is not required, and installation is further facilitated.

The main body may have a screw hole radially penetrating therethrough, and a set screw may be screwed into the screw hole. In this case, after the main body is placed on the installation rod or guardrail post, the set screw can be tightened and the main body can be firmly fixed to the bar or the post, and can be easily removed by loosening the set screw. You can also.

The plurality of light emitting diodes may be arranged at equal intervals in a circumferential direction on a plurality of concentric circles having a common center with the reflection surface. In this case, since the light emitting diodes can be evenly arranged over the entire reflecting surface, a large outline can be drawn even with a small number of light emitting diodes. Therefore, the driver can be effectively recognized with a small amount of power.

5c is a connected first series, 15b is a second series independent of the first series, and each is connected to the plus side and the minus side of a battery (not shown) via a conductor 9. . The wiring 15 is not limited, and for example, a printed board may be used.

The power supply unit 10 has a cylindrical shape as a whole and includes a battery (not shown). A lead 9 connected to the battery extends from the upper part. There is no limitation on the battery used, and an optimum battery can be selected according to the power used and the usage time of the light emitting diode 8, and for example, a commercially available dry battery can be used.

Further, the power supply unit 10 includes blinking control means (not shown) so that the light emitting diode 8 blinks. The blinking control means may be appropriately provided as needed. However, when the light emitting diode 8 is blinked, it is possible to obtain an effect of actively calling attention to the driver. It is to be noted that known means such as a device for turning on / off a wiring using a transistor can be used as the blinking control means.

Further, an on / off switch 11 and a pattern changeover switch 12 are protruded from the power supply section 10 so that the light emitting diode 8 can be easily turned on and off, and the light emission pattern can be easily switched. In addition, as a light emission pattern,
