Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is attached to a railroad crossing gate or stop line, or to a railroad crossing gate and stop line, and when a train is passing, it alerts a passerby by interlocking with a railroad crossing alarm. It concerns a warning light at a railroad crossing.

[0002]

2. Description of the Related Art Conventionally, when a railroad crossing is provided with a stop line and an alarm device with a warning light warns of train passage, and a yellow and black zebra pattern is closed, the circuit breaker closes. It is urging that vehicles should not enter. In some cases, LE
In some cases, a light-emitting body made of D is attached to a breaker, and the light-emitting body emits light and blinks in synchronization with an alarm.

[0003]

However, in the case where the above stop line is difficult to see, the visibility is particularly poor at night, and the alarm is hard to hear from a distance, and the alarm light is difficult to see depending on the location where the alarm is installed. There is. In addition, yellow / black zebra-patterned circuit breakers have poor visibility at night, and if the circuit breaker has LEDs installed, the number of LEDs is heavy and point emission, so there are few. It is hard to see and lacks attention, and if many are installed, there is a problem that installation is troublesome and expensive.

Therefore, the present invention solves the above problems,
Improve the visibility of breakers and stop lines, especially at night,
The purpose of the present invention is to provide a reminder light for level crossings that can be easily installed while at the same time effectively encouraging people to cross the level crossing.

[0005]

In order to achieve the above object, the present invention has the following constitution. That is, the warning light at a railroad crossing according to the present invention is attached to a crossing gate or / and a stop line of the railroad crossing, and emits light linearly to the light emitting means in conjunction with a warning signal of the railroad crossing. It is characterized in that it is provided with a light source means which emits light and causes the light emitting means to emit light or blink in cooperation with an alarm device.

The light source means may use an alarm light of an alarm device as a light source, and the light from the alarm light may be directly guided to the light emitting means. By using the alarm light in this manner, another light source means, another power supply device for emitting light from the light source means, etc. are not necessary, and further, a controller and labor for interlocking with the alarm device can be omitted, and the device can be simplified. . However, other light source means such as halogen lamps, high-intensity discharge lamps, light emitting diodes, etc. are used, and these light source means are linked with an alarm device to emit and blink, and the light is guided to the light emitting means to emit and blink. You may let me. In this case, the power source used may be a solar cell or a commercial power source. Further, it is preferable to dispose a color filter on the front surface of the other light source means and guide the light to the light emitting means through the color filter because the emission color can be easily changed.

The light emitting means may be attached only to the crossing gate of the railroad crossing, or may be embedded along the stop line, that is, on, near, in front of the stop line, or the like. It is preferable to be attached along the line because it can more effectively call attention.

The type of the light emitting means is not particularly limited as long as it emits light linearly by emitting the light guided from the light source means. It is preferably composed of a long tubular light-emitting body which is housed in a flexible tube and has a core having a higher refractive index than the flexible tube. Compared with other LED and other light emitters, this tubular light emitter does not require electrical wiring, so it has excellent water resistance, is easy to maintain, and has a light output that does not emit from the outer peripheral surface. The light incident on one end of the core from the light source means is reflected by the boundary surface between the flexible tube and the core, and by repeating this reflection, part of the light is emitted from the outer peripheral surface while being transmitted to the other end of the core. As a result, the light is emitted uniformly and linearly. Moreover, since the tube-shaped light emitter can be made thicker than the optical fiber, it is incomparable.
A large amount of light can be made incident to increase the amount of light emitted from the outer peripheral surface, and the emission brightness can be increased. Furthermore, since this tubular luminous body can be easily bent, it can be easily attached, and the color of light emitted can be changed by using a color filter.

It is preferable that the flexible tube is made of a translucent material so that the incident light is emitted from the outer peripheral surface, since the light is emitted from the entire outer peripheral surface. However, the flexible tube is made of a light shielding material. , Partially forming a light leak part,
Alternatively, the outer peripheral surface of the flexible tube made of a light-transmitting material is covered with a light-shielding material, and the light-shielding material is partially cut out to form a light leakage portion so that the light is emitted in a dot line shape. Alternatively, a part of the flexible tube made of a light-transmitting material may be covered with a light-shielding material along the longitudinal direction so that light is not emitted from the entire outer peripheral surface and only from the side facing the passerby. It may be emitted.

The boundary surface where the core and the flexible tube are in contact with each other, that is, the inner wall surface of the flexible tube may be smooth, but if fine irregularities are formed, the incident light is irregular due to the fine irregularities. This is preferable because a large amount of light is reflected and emitted from the outer peripheral surface.

The material forming the flexible tube is not particularly limited as long as it is flexible and can be formed into a tube shape and has a low refractive index. Synthetic resins such as polyethylene, polypropylene, polyvinyl chloride, polyamide, polystyrene-butadiene copolymer, butyl rubber, EPDM, acrylonitrile-butadiene copolymer, fluororubber, silicone rubber, etc. are used, and silicone having a particularly low refractive index is used. Polymers and fluoropolymers are preferably used, and these materials may be used alone or in combination of two or more kinds, and may be a single layer or multiple layers.

The core is not particularly limited as long as it has a higher refractive index and a light transmitting property than the flexible tube, and a viscous liquid state, a solid state or a gel state is usually used. . Examples of the viscous liquid or gel core include polyols such as polyethylene oxide, polypropylene oxide and glycerin, polyol esters, polyol ethers, phosphoric acid esters such as chloroethyl phosphate, dichloropropyl phosphate, liquid paraffin and fluoro oil. , Silicone oil, polyisobutylene, polysiloxane-modified polyether, an aqueous solution of an inorganic salt, a polymer solution obtained by diluting a polymer with a suitable solvent, and the like, and a solid core such as polymethylmethacrylate.

When the core is in the form of a viscous liquid or gel, both ends of the flexible tube are made of a translucent material such as glass or quartz so as not to leak from the flexible tube. It is preferable that the solid core is accommodated in the flexible tube by inserting a monomer of synthetic resin into the flexible tube and polymerizing it in a properly shaped state. A preferable example of such a tubular luminous body is Ray Duck Light manufactured by Bridgestone Corporation.

The light emitting means composed of the tubular luminous body as described above may be attached to the breaker or the stop line as it is, but particularly in the case of the tubular luminous body embedded in the stop line. When the tube-shaped luminous body is fitted and mounted in the transparent long protective tube, the tubular luminous body is not exposed to the outside and is protected by the transparent long protective tube. It is prevented from being damaged. The transparent long protective tube is not particularly limited in its cross-sectional shape as long as it has an insertion hole into which the tubular light-emitting body is inserted in the longitudinal direction, and may be divided into a plurality of pieces in the longitudinal direction. Good. The transparent long protective tube is generally formed of a hard material made of transparent resin such as colorless or colored light, synthetic resin such as polycarbonate or acrylic resin. Also, by covering a part of the transparent long protective tube with a light-shielding material, the light passing through the transparent long protective tube from the tubular light-emitting body is transmitted in a dot line shape or faces a passerby. You may make it permeate | transmit only to the side.

[0015]

According to the warning light at the level crossing according to the present invention, since the light emitting means for emitting and blinking linearly in conjunction with the alarm device is attached along the breaker or / and the stop line, particularly at night. It is possible to improve the visibility of the breaker and stop line in the car and effectively alert the crossing to prevent crossing accidents. Since it does not use a point illuminant like the LED of the above, it is easy to install, and since the light emitting means emits light by emitting the light guided from the light source means, it does not require electric wiring and therefore is water resistant. Excellent and easy to maintain.
