Embodiment Construction

[0029] Embodiments of the door device according to the present invention will be described below. Among them, a fall prevention fence for preventing passengers waiting for a train on the platform from falling into the track from the platform will be described as an example.

[0030] figure 1 It is schematic diagram showing setting example of fall prevention fence of platform. figure 1 (A) is a plan view of the platform viewed from above, figure 1 (B) is the plan view which looked at the platform side end part from the opposite side. Such as figure 1 As shown, this fall prevention fence has a plurality of movable fences 1 provided at appropriate intervals (2m to 3m intervals) along the side ends of the platform. Each movable fence 1 corresponds to the gate apparatus according to the present invention.

[0031] As described above, the door intervals vary depending on the type of train. The fall prevention fence has nothing to do with the type of trains that are parked on t...

Abstract

The invention provides a door device capable of overcoming limits of an application range by an occasion and the environment. And when problem appears in a process that a stopping rod is arranged in the lower part of the door to restrict the entrance and the exit of human and vehicle, the restrict can be removed easily. In the invention, movable support posts (11) are installed on the fixed support posts (11) along a vertical direction in a sliding manner. The stopping rod (14) is bridges between two neighboring movable support posts (12) in a manner of freely sliding in a vertical direction. Two ends of the stopping rod (14) connect with non-end belt (31) on driving pulleys (32, 33) arranged in the movable support posts (12). The stopping rod (14) drives the non-end belt, thereby sliding along the vertical direction. Besides, a connection shaft (34) rotating along with the driving pulley (33) is installed between the driving pulleys (33) in the upper side of two movable support posts (12).

Description

technical field [0001] The present invention relates to a door device for restricting the passage of people, vehicles, etc. at an entrance, and more particularly to a door device for restricting the passage of passengers getting on and off trains on a platform. Background technique [0002] Conventionally, in order to prevent passengers from falling into the tracks from the platform, railway companies have studied the installation of fall prevention fences along the side ends of the platform. The fall prevention fence not only prevents passengers from rolling down from the platform into the track, but also must ensure the passage of passengers on and off the trains that stop on the platform. For example, there is a fall prevention fence provided with a sliding door that slides in the horizontal direction and opens and closes at a position facing the door (car door) of a train that stops on the platform (see Patent Document 1). The fall prevention fence is configured such th...
