Thereby, the terminals T1 and T2 are electrically interconnected, the light emission diodes 2 emit light and the presence of the pole is reported to the driver of a vehicle utilizing the railroad crossing.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety illuminating device which is attached to an opening / closing pole of a railroad crossing and makes the presence of the railroad crossing recognizable by illuminating the illumination, and similarly prevents the occurrence of a railroad crossing accident. .

[0002]

[Background of the Invention] There have been many railroad crossing accidents in recent years, which have become a social problem. The main cause of this is an accident that destroys a pole at a railroad crossing due to a traveling vehicle or the like, and this is often due to the fact that the presence of the railroad crossing pole is unknown at night or in the dim daytime.

[0003]

An object of the present invention is to ensure the safety of a railroad crossing by allowing a driver who is traveling at night or dim daytime and the presence of an opening / closing pole for railroad crossing to always prevent the occurrence of a railroad crossing accident. It is to provide a lighting device.

[0004]

[Features of the Invention] The safety lighting device for level crossings of the present invention is
A plurality of lighting device main bodies each including a mounting plate in which a plurality of light emitting diodes are horizontally arranged at equal intervals, and a cover body provided on the mounting plate and having a diffusion lens such as a convex lens at a portion facing the light emitting diodes; Turns on / detects the tilt of the solar system that makes the diode emit light, the storage battery, and
A switch system for turning off and an electric device main body in which the switch system is electrically connected to the plurality of lighting main bodies, and the electric device main body and the plurality of lighting main bodies are attached to an opening / closing pole of a railroad crossing. It is characterized by

Thus, when the open / close pole of the railroad crossing is horizontal, that is, when the train is running and the railroad crossing is closed,
Since the switch system of the electric device is in the "ON" state and is electrically connected to this switch system, the light emitting diode emits light, and the driver of the vehicle using this railroad crossing is aware of the existence of the pole. is there. In this case, the light emitting diode does not simply turn on
By incorporating a mechanism, such as flashing by a method or allowing the flow in the traveling direction of the train, in the electric device body, the driver of the vehicle can be reminded more.

Then, when the train passes the railroad crossing, the opening / closing pole rises, and the switch system of the electric device main body becomes "O".
FF ”, and as a result, the lighting of the light emitting diode of the main body of the lighting device is cut off. In this way, when there is no train running on the railroad crossing, the light emitting diode does not light up, so power can be saved.
This is inexpensive because the solar system or the storage battery does not need to have a relatively large capacity.

The electric device main body and the plurality of lighting main bodies may be separately attached to the opening / closing poles of the railroad crossing, or the electric device main body may be incorporated in the lighting main body.

[0008]

[Embodiment] In the figure, (1) is a horizontally long illumination main body, whose cross section is "U".
It is made of transparent plastic material in the shape of a letter. A mounting plate (3) having a plurality of light emitting diodes (2) mounted at equal intervals is fitted to the open surface of the U-shaped lighting body (1).

The inner end surface of the lighting device body (1) constitutes a convex lens (4) at the same interval as the light emitting diode (2). In this illumination body (1), the convex lens (4) part and the part where the mounting plate (3) is fitted can be molded at the same time, but as shown in FIG. 4, a cap body having the convex lens (4). An outer wall member (6) in which the cap body (5) is fitted to the portion (5) and the outer edge and the mounting plate (3) is fitted to the inner edge.
It is preferable to use a resin material provided with and colored red.

(7) is a band member (8) which is wound in a string shape by a band main body for mounting the lighting main body on a pole (A) of a railroad crossing, which will be described later, and the diameter of the band member (8) is enlarged or reduced. It comprises a known tightening member (9) capable of holding the state. Therefore, a guide member (10) having a "concave" cross section is provided at an appropriate position on the back surface of the illumination body (1), and the band member (8) is inserted therethrough.

Reference numeral (11) denotes a casing-shaped electric device main body, on one surface of which a solar system (12) is provided, and a storage battery (13) and a switch system (14) are incorporated. There are many possible switch systems (14) such as a well-known ball switch system and a switch system using a cam plate. In FIG. 5, a mercury switch mechanism is shown. That is, (15) is a mercury channel having a substantially "<" shape, and (16) is mercury that can be slid by being guided in this channel. Further, a terminal (T1) electrically connected to the solar system (12) via a storage battery (13) is provided at the lower end of the passage (16).
And a terminal (T2) connected to the light emitting diode (2), and the mercury (15) is connected to these terminals (T1) and (T2).
They are adapted to be electrically connected when placed in between.

A plurality of proof bodies (1) are attached to the crossing poles (A) at equal intervals. If this method of attachment is temporarily assumed, the band member (8) of the band body (7) is inserted into the guide member (10) provided on the attachment plate (3) of the lighting body (1), and the band member (8) is inserted into the band member (8). The pole (A) is passed through and tightened with the tightening member (9) so that the pole (A) is securely fixed. Next, the electric device body (11) is attached to the pole (A) at an appropriate position by an appropriate means. This mounting position may be anywhere as long as it can be rotated in conjunction with the pole (A).

Next, although not shown or described, the switch system (14) provided in the electric device body (11)
And the plurality of light emitting diodes (2) of the plurality of lighting device bodies (1) are electrically connected. In FIG. 1, (B) is a column mounted near the railroad crossing, and a pole (A) is attached to this column, and a known pole rotation system for rotating the pole (A) is built in.

As shown in FIG. 5, the electric device main body (11) is in a state where the pole (A) is horizontal as shown by the solid line in FIG. 1, that is, a state in which a train or the like is running and the railroad crossing is closed.
Switch system (14) presents a vertical "<"-shaped mercury passage (15). Therefore, the mercury (16) in this passage (15) is located at its lower end, that is, between the terminals (T1) and (T2). Therefore, each terminal (T1) (T
2) is electrically connected, and the group of light emitting diodes (2) emits light, so that the driver of the vehicle using this railroad crossing is aware of the presence of the pole (A).

In this case, the light emitting diode (2) group is not simply turned on, but a mechanism for blinking by a proper means or method and for allowing the light emitting diode (2) to flow in the traveling direction of the train is incorporated in the electric device body (11). It is essential that it be done. When the train passes the railroad crossing, the pole (A) rotates as shown by the chain line in FIG. 1, so that the electric device body (11) also rotates as shown by the chain line in FIG. As a result, the mercury passage (15)
Is a horizontal "C" shape, the mercury (16) moves laterally, and the electrical connection between the terminals (T1) and (T2) is cut off, and as a result, the light emitting diode (2) group of the lighting device main body (1) lights up. Is cut off.

As described above, when there is no train running on the level crossing, the light emitting diode (2) does not light up, so that it is possible to save electricity, which is inexpensive because the solar system (12) or the storage battery need not have a relatively large capacity. .
