Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a delineator as a facility attached to a road.

[0002]

2. Description of the Related Art As is well known, line-of-sight guides are installed at predetermined intervals along the road in order to clearly indicate the position of the road edge, median strip, road alignment, etc. This is for effectively guiding the eyes of the vehicle driver when the visibility is bad.

FIG. 4 shows an example of installation of a line-of-sight guide mark in a curved section of a road. The line-of-sight guide mark 1 in the illustrated example is attached to a protective fence (guard rail) 2, and as shown in FIG. 5, it is composed of a support column 3 and a reflector 4 attached to the tip of the support column 3. The container 4 includes a reflector 5 and a mounting frame 6 for the reflector. The reflection plate 5 is a resin disc-shaped member that retroreflects an incident light beam from a vehicle headlight, and its back surface is processed to reflect the light beam and obtain a sufficient amount of reflected light. ing.

Incidentally, as the installation form of the gaze guide 1,
Not only is it attached to the guardrail 2 as described above,
It can be installed independently from the road surface by the pillar 3, or the pillar 3
In some cases, the reflector 4 may be omitted and only the reflector 4 may be directly attached to, for example, a tunnel wall surface. Further, only the reflector 5 may be incorporated into a road tack installed on the center line of the road.

[0005]

By the way, since the reflector plate 5 in the conventional general visual guide mark 1 as described above merely retroreflects the incident light beam, the visibility from a long distance is not always sufficient. is not. In particular, dirt, dust, various pollutants contained in exhaust gas, etc. are likely to adhere to the surface of the reflection plate 5, and as a result, the surface reflectance decreases with the passage of time and the visibility is reduced in a relatively short period of time. Is greatly damaged. For this reason, the conventional general gaze guide 1
Requires frequent cleaning, which requires a great deal of labor and cost, and cleaning work may be difficult depending on the installation location.

In view of the above circumstances, it is an object of the present invention to provide an effective line-of-sight guide which can sufficiently improve the visibility and can maintain the visibility for a long time and reduce maintenance cleaning. .

[0007]

In view of the above-mentioned circumstances, in the visual guide mark of the present invention, a large number of light-emitting bodies which emit light from a power source are attached to a substrate, and are replaced with a reflector plate in a conventional general visual guide mark. It is the one that is used. In this case, a light emitting diode is preferably used as the light emitting body, and the power source of the light emitting body is preferably composed of a solar cell and a storage battery. As the substrate, it is conceivable to use a reflection plate used in a general visual guide marker in the past, that is, one that retroreflects an incident light beam, and it is conceivable that the substrate forms a convex curved surface.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, specific embodiments of the present invention will be described. FIG. 1 shows an example of a line-of-sight guide mark of the present invention. This line-of-sight guide mark 10 includes a support 11 and a guide sample body 13 attached to an upper end of the support 11 via a mounting member 12.
It has. The guiding specimen body 13 includes a substrate 14 and
A back cover 15 is mainly formed, and light emitting diodes 17 as light emitting bodies are mounted in a large number of mounting holes formed over the entire surface of the substrate 14 with their tips exposed to the front surface side of the substrate 14. Has become. The electric wires 18 led out from the respective light emitting diodes 17 are bundled and wired in the mounting member 12 and the pillar 11, and are connected to a power source 19 installed outside.

The substrate 14 is a convex curved surface forming a part of a spherical surface, and the material thereof is the same as that of the reflector 5 in the conventional general visual guide marker 1 as shown in FIG. In order to retroreflect incident light rays from the front surface side, a resin-made one that has been processed to reflect the light rays to the inner surface side is used.

A commercial power source may be used as the power source 19, but in this example, a solar cell 20 and a storage battery 21 charged by the solar cell 20 are used as the power source 19, and the sun is used during the daytime (in fine weather). Storage battery 21 by battery 20
Is charged, and the light-emitting diode 17 is turned on by discharging the storage battery 21 at night, during rainfall, when fog occurs, and the like. In this case, a control circuit for automatically turning on the light emitting diode 17 when necessary is provided by, for example, detecting a timer or ambient brightness. In addition, when using the solar cell 20 and the storage battery 21 as the power source 19, the small solar cell 20 and the storage battery 21 may be independently provided in each of the line-of-sight guidance marks 10, or a plurality of them may be installed in a certain area. A power source 19 of a scale capable of supplying power to the base line-of-sight guide 10 may be installed in each area.

The line-of-sight guide 10 having the above structure is supported by a guard rail or the like as in the conventional one, or the support 1
It is made to stand by itself and installed in large numbers along the road at predetermined intervals for use. Then, at least when the visibility is bad at night or during rainfall, when fog is generated, etc., the light emitting diode 17 is energized to light all of them at all times including the daytime. The visibility can be remarkably improved in comparison with. Not only that, but the above-mentioned gaze guide 10 emits light itself, not a passive one that merely reflects an incident light beam as in the conventional one, and even if it is small, it has a large brightness. Since a large number of the obtained light emitting diodes 17 are used, even if a small amount of earth, sand, dust, contaminants or the like adheres to the surface of the substrate 14 or the light emitting diodes 17 themselves, the visibility is not significantly deteriorated immediately. It is possible to reduce the cleaning work that has been required to be frequently performed in the conventional general gaze guide 1.

Further, the light emitting diode 17 used in the above gaze guidance indicator 10 is not only inexpensive,
Since it has a sufficient life and can obtain sufficient brightness with low power consumption, it can be installed in comparison with the case where other light-emitting body other than the light-emitting diode 17, for example, an ordinary incandescent lamp or a fluorescent lamp is used. It is extremely advantageous in terms of expenses and operating costs. Further, since the light emitting diode 17 has low power consumption and sufficient brightness can be obtained, the power source 19 thereof may have a small capacity, and particularly when the solar cell 20 is used, a small solar cell 20 and a small capacity storage battery. It is sufficient to use No. 21 and, naturally, installation work is easy because the power drawing work and wiring work required when using a commercial power source are unnecessary. However, in the present invention, the light emitting diode 17
Is not limited to the use of, and the power source is not limited to those using solar cells,
Other light emitters and other power supply equipment can be arbitrarily adopted.

Further, since the above-mentioned line-of-sight guide 10 itself emits light, it does not necessarily have the function of retroreflecting the incident light rays from the headlight of the vehicle as in the conventional one, but the above-mentioned function is not necessary. If a reflecting plate is used as the substrate 14 as described above, it functions in the same manner as the conventional one when the light emitting diode 17 is not lit, and therefore it is preferable to do so. Further, when the substrate 14 is simply a flat plate, the light emitted from each light emitting diode 17 is limitedly emitted in a single direction, so that it is visible only in a specific direction. By forming the substrate into a convex curved surface as described above, light is emitted over a wide range as indicated by an arrow in FIG. 1 (a). The visibility from can be further improved.

The light emitting diode 17 as a light emitting body
May be kept on all the time or may be blinked if necessary. The color of the light emitting body may be arbitrary, but for example, the light emitting bodies of two kinds of colors are mixed and are selectively turned on to change the color, or the light emitting diode 17 is used as the light emitting body. In some cases, it may be possible to change the color of the light emitted by itself.

Further, the line-of-sight guide mark of the present invention is not limited to the form in which it is supported and supported by the support column, but can adopt an appropriate form depending on the installation position. Other examples are shown in FIG. 2 and FIG. Shown in.

The line-of-sight guide mark 30 shown in FIG. 2 has a form in which the support 11 and the mounting member 12 of the line-of-sight guide mark 10 are omitted and only the guide sample body 13 is provided. It is designed to be attached directly. In this case, although illustration is omitted, the power source is installed at an appropriate position (of course, when a solar cell is used as a power source, it is installed outside the tunnel), and the power source is connected to each gaze guide 30. Wiring for supplying power may be performed.

Further, the line-of-sight guide mark 40 shown in FIG. 3 is incorporated into a road stud 41 which is installed so as to slightly project on the center line L of the road surface. Substrates 43 having a large number of light emitters 42 are respectively attached to both sides of a road stud 41 which is inclined with respect to the center line L so as to face the lane side. In this case as well, as in the case of the above-mentioned line-of-sight guide 10, a light-emitting diode is used as the light-emitting body 42, and a solar cell may be used as its power source, and a reflective plate that retroreflects incident light rays is used as the substrate 43. It is preferable to use the substrate 43 so that the substrate 43 is curved so as to have a convex curved surface, and is arranged so as to be slightly upward so that the light from the light emitting body 42 is emitted in a wide range.

[0018]

As described above, since the line-of-sight guide of the present invention has a structure in which a large number of light emitters that emit light from a power source are attached to a substrate, it is more effective than the conventional line-of-sight guide using a simple reflector. Thus, not only the visibility can be remarkably enhanced, but also the visibility can be maintained well for a long period of time, and maintenance such as cleaning can be reduced. The use of a light-emitting diode as the light-emitting body is particularly preferable because a sufficiently small size and low power consumption can provide sufficient brightness, and if a solar cell is used as a power source, commercial power can be drawn in and wiring work can be performed. It can be omitted and installation work can be simplified.
