FALL PREVENTING DEVICE

PROBLEM TO BE SOLVED: To provide a new fall preventing device, simple in installation work to a platform. SOLUTION: A movable step device 100 pivots a central movable step 110 by rotary shafts 126 and 146 arranged on the left and right of a recessed part 10 of digging down the platform 2. At this time, an installation relative position is set as a position offset downward more than the rotary shafts by offsetting the movable step 110 of a horizontal attitude on the track side to the rotary shaft 126 and the rotary shaft 146. Thus, only a lower part than the rotary shafts of a driving mechanism part is stored in the recessed part 10, and the rotary shafts and its upper part become a layout exposed on the platform 2. The depth required for the recessed part 10 may be shallower than usual without requiring to wholly store the driving mechanism part (particularly, a driving motor). COPYRIGHT: (C)2011,JPO&INPIT
