<P>PROBLEM TO BE SOLVED: To solve such a problems that an entrance/exit sliding device for a movable door of a conventional movable platform fence makes a sliding part of a one-point support subject to severe abrasive wear because horizontal and vertical loads are concentrated on the sliding part, and also the movable door becomes unstable due to the generation of lateral oscillation in the upper part and the lower part of the movable door because of the one-point support. <P>SOLUTION: A movable platform fence includes: a door pocket erected along the side edge on a platform and partitioning the platform side and the track side; and a movable door stored in the door pocket so as to freely come in/out thereto/therefrom and opening and closing a passenger entrance/exit on the platform. An upper rail and a lower rail are provided side by side in the door pocket to slide and guide each of an upper support and a lower support provided on the movable door. An upper sliding part is provided at the upper support so as to receive the horizontal load of the movable door while a lower sliding part is provided at the lower support so as to receive the vertical load of the movable door. <P>COPYRIGHT: (C)2012,JPO&INPIT |
