Embodiment Construction

[0033] 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.

[0034] 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. like 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.

[0035] 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 the ...

Abstract

The invention provides a door device. The influence of an occasion and an environment for arrangement of the device upon the applied scope of the device is inhibited, and the safety of people around the device when accidents occur is improved. A movable fence (1) becomes balanced in a way that the gravity applied to a heavy object (29) is slightly larger than the gravity applied to a movable pillar (12). In the movable fence (1), when the movable pillar (12) is positioned on a lower limit place, a block (25) is embedded into the recessed portion (24a) of a connecting member (24) so that the movable pillar (12) is prevented from sliding upward. In addition, the regenerative braking of a motor (52) is driven by the movable pillar to prevent the movable pillar from sliding upward. When the movable fence (1) is lifted upward by the force that is larger than the sum of the clamping force of the block (25) and the regenerative braking force of the motor (52) driven by the movable pillar, the block (25) is separated from the recessed portion (24a) of the connecting member (24). Therefore, the movable fence (1) can be lifted upward by the force that is larger than the regenerative braking force of the motor (52) driven by the movable pillar.

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...
