Description

  The present invention relates to an alarm device, and more particularly, to an alarm device that alerts a passerby or a driver of an automobile to information such as approach of a vehicle at a railroad crossing or a pedestrian crossing.

  At a level crossing for transportation, a vehicle such as a train, a streetcar, a route bus, a monorail, a subway traveling on the ground, and a road crossing the level crossing, for example, an automobile, a truck, a bus, or the like There is a high risk of traffic accidents due to crossing with passers-by. Therefore, at a level crossing in a transportation system, there is an alarm device that alerts a driver, such as an automobile, a truck, or a bus traveling on a road crossing the level crossing, or a passerby by approaching a vehicle traveling on the route. Is provided. Here, the alarm device includes, for example, a flashlight and a warning light installed at a railroad crossing, but is not limited thereto, and includes a device provided in combination with a projector, a warning indicator light, a speaker, and the like.

  In addition, even on a pedestrian crossing without a traffic light, there may be provided an alarm device that alerts a person who is approaching a vehicle such as an automobile, a truck, or a bus to call attention. In addition, an alarm is provided to alert the driver of vehicles such as cars, trucks, buses, etc. traveling in other directions about the approach of vehicles such as cars, trucks, buses, etc. traveling in one direction on intersecting roads. Sometimes.

  In these alarm devices, conventionally, an omnidirectional alarm device devised to reliably notify traffic information over a wider angle range has been proposed. These alarms are, for example, a type in which light emitters such as light emitting diodes are arranged in a circular shape on a substrate, and a light emitter such as a red light emitting diode blinks to notify, and a lens has a spherical or cylindrical shape and is provided inside. There has been proposed a form in which a red light emitting diode is flashed in all directions for notification.

  For example, Patent Document 1 discloses an omnidirectional railroad crossing alarm that does not change the shape of an alarm or the like depending on the viewing angle. In this case, a red light emitting LED mounting board is attached to a polygonal multi-faceted board mounting frame, and a multi-faced light emitter is attached to each side of the LED mounting board to provide a light emitting surface for a flashing lamp. It is described that it is oriented in all directions of a square and the polyhedral light emitter is installed in a globe using a spherical lens.

  Patent Document 2 discloses an omnidirectional railroad warning light that enables visual recognition from all directions of 360 degrees. Here, a large number of light emitting diodes are mounted in a semicircular shape on both sides of the light emitting diode substrate, and four of the light emitting diode substrates are joined at 90 degrees so that the semicircular diameter portions are perpendicular to each other at the center position of the lamp body. It is described to fix at intervals.

  Conventional alarm devices have been alerted by arranging light-emitting elements such as light-emitting diodes in a circular shape, or by arranging them in a shape simulating a circle and blinking. Therefore, it is suitable for informing relatively simple information such as “whether or not the vehicle is approaching”. However, this method is not suitable for alerting a vehicle driver or the like with a clearer message by, for example, symbol information such as “x” or character information such as “danger”.

  Furthermore, in a conventional alarm device in which light emitting elements such as light emitting diodes are arranged in a circular shape or arranged in a shape imitating a circular shape, complicated shape information such as symbol information and character information is visually recognized from all directions. There was a problem that it was difficult to convey the meaning accurately.

Accordingly, it is possible to easily provide a function of attaching and fixing the upper lid and the lower lid to the light emitting panel by utilizing the joint portion provided for connecting and assembling the light emitting panels.

  Moreover, it is preferable that a lower cover is hung from the baseplate of a some light emission panel by the chain for fall prevention of an alarm. Thereby, for example, it is possible to prevent an accident such as dropping the lower lid at the time of installation of the alarm device or maintenance.

  Moreover, it is preferable that a curved surface is formed so that the alerting | reporting apparatus may have the outer surface of a light emission panel bulged to the outer side. This makes it possible to visually recognize the symbol information or character information displayed on the light emitting surface even for the driver of the vehicle who has seen the alarm device obliquely from the side of the light emitting panel, and to accurately convey the meaning. .

  In addition, it is preferable that the alarm device has a side surface in which the outer surface of the light-emitting panel displays the symbol information or the character information and the back plate from which the lens unit is cut out, and the lens unit stands up from the back plate. Moreover, it is preferable that the indicator emits light emitted from the light emitting element also from the side surface of the lens unit. Thereby, the character information or the symbol information displayed on the light emitting surface can be accurately recognized from the side surface of the lens unit even for the driver of the vehicle who has seen the alarm device obliquely from the light emitting panel.
