Embodiment Construction

[0036] Embodiments of the door device according to the present invention will be described below. Among them, an example of a fall prevention fence for preventing passengers waiting for a train on the station platform from falling into the track from the station platform will be described.

[0037] figure 1 It is a schematic diagram showing an installation example of the fall prevention column of the station platform. figure 1 (A) is a plan view of the station platform viewed from above, figure 1 (B) is a plan view looking at the side end of the station platform from the opposite side. Such as figure 1 As shown, the fall prevention fence is provided with a plurality of movable fences 1 at appropriate intervals (2m to 3m intervals) along the side ends of the station platform. Each movable fence 1 corresponds to the door device according to the embodiment of the present invention.

[0038] As described above, the door intervals differ depending on the type of train. With r...

Abstract

The invention provides a door device which allows safely and smoothly opening and closing of an entrance. Two fixed pillars (11) are vertically arranged on both sides of the entrance, and movable pillars (12) are installed in such a manner that the movable pillars (12) are freely and vertically slidable relative to the fixed pillars (11). One or more restriction poles (13, 14) are arranged between the movable pillars (12). The restriction poles (13, 14) can be lifted up by sliding the movable pillars (12) upwards to allow passing from the entrance, and the restriction poles (13, 14) can be lowered down by sliding the movable pillars (12) downwards to forbid passing from the entrance. A control portion (50) detects the presence of objects between two fixed pillars (11) and between two movable pillars (12) and control the opening and closing of the door according to the detection result.

Description

technical field [0001] The present invention relates to a door device for restricting the passage of people and vehicles at the entrance and exit, and in particular to a door device installed on a station platform to prevent passengers getting on and off the train from rolling down from the station platform into the line. Background technique [0002] In the past, in order to prevent passengers from rolling into the line from the station platform, the railway company promoted the method of setting fall prevention bars along the side ends of the station platform. This fall prevention bar not only prevents the passenger from rolling into the line by the station platform, but also must be used to ensure the passage of the trains that stop on the station platform up and down. [0003] As a conventional fall prevention fence, it is known to provide a sliding door that slides to open and close in the horizontal direction at a position facing a train door (vehicle door) that stops ...
