Description

  The present invention relates to a handrail having an information display unit such as Braille.

  Conventionally, for example, in public facilities such as stations, information display units such as Braille are provided on stair railings to provide information to visually impaired persons.

  However, the conventional one uses a thin metal plate or braille stamped information display plate attached to the surface of the handrail with rivets etc. so that it does not hinder the walking motion of the handrail. There is a risk that the user may be injured due to a peeled state or a state where the end of the metal plate has jumped up. Further, there is a problem that the braille portion is worn out after being used for a long period of time, and the stamped braille information is not sufficiently transmitted. Therefore, it is necessary to replace the old information display plate that has been damaged or the like with a new information display plate.

  Also, a structure in which a guide component part with a cover body with braille formed on the surface is incorporated into a handrail main body via a joint member, or in a state in which the handrail main body is inserted at both ends of the guide component part. There is known a guide handrail (see, for example, Patent Document 1).

Further, a handrail structure is known in which a tubular body having an information display section such as Braille on the surface is connected to a handrail via insertion tubes inserted at both ends of the tubular body (see, for example, Patent Document 2). .

  However, in the case where a conventional information display plate in which braille is engraved on a metal plate or a seal is attached to the surface of the handrail, a new information display plate is attached after cutting the rivets and removing the old information display plate. The replacement work takes time. Moreover, even after the replacement, as described above, there is a problem that problems such as peeling and jumping of the information display plate are not solved.

  On the other hand, in the technique described in Patent Document 1, there is no need to replace the information display plate itself, but a step is generated in the joint portion between the guide component and the handrail body, and the opening of the guide component is formed. Since a lid (information display plate) with braille formed on the surface is attached, a step is generated between the guide component and the information display plate. Therefore, safety is not sufficient for the visually impaired.

  In the technique described in Patent Document 1, the guide component with the information display plate attached is incorporated into the handrail main body via a joint member, or the handrail main body is inserted at both ends of the guide component. Since the handrail is assembled in the state, it takes time to align the handrail main body and the guide component, such as centering, and there is a gap at the joint between the handrail main body and the guide component, making it difficult to fix firmly. There is a problem.
