Description

  The present invention relates to a movable platform fence, and more particularly, to a movable platform fence that is installed on a platform and accommodates a door in a door pocket when a train stops at a fixed position so as to be able to get on and off the train.

  In order to allow passengers to fall on the tracks from the platform or to relieve the wind pressure when passing through high-speed trains, a movable platform fence (home door) is installed on the side edge of the platform. This movable platform fence generally has a door bag body standing along the side edge of the platform, and a door body provided so as to be able to advance and retreat with respect to the door bag body. The door body must withstand external forces from passengers and the wind pressure of passing trains. On the other hand, the door body is required to have sufficient strength and light weight in order to reduce the burden on the platform and to enable smooth opening and closing. There is also a need to make it. For this reason, there are many examples of adopting a frame structure in which a frame that is firmly framed is used as a skeleton, a panel material is arranged on the front and back of the skeleton, and a honeycomb material is sandwiched between the panel materials (for example, patent documents) 1 and 2).
