PURPOSE: An auxiliary foothold system for a platform is provided to safely get on and off since an auxiliary foothold automatically comes in and out in a space where the interval between the floor surface of the platform and the entrance of a train is wide if the platform of a subway or a railway is round or abnormally installed. CONSTITUTION: An auxiliary foothold system is composed of a driving unit connected with a shaft to interlock when a driving motor is driven while a driving motor(1), a working shaft(2), a pinion gear unit(3) and an over running clutch unit(4) are vertically arranged in parallel with the surface in a space unit(130) where the both ends of the horizontal and vertical platform(110,120) in the platform(100) meets, a shift lever unit of which an upper end is combined with the inner side end(7) of a plate unit to rotate and a central part is combined with a pivot(8) and a plate unit made up to appear and disappear toward the entrance of a vehicle since a shock absorbent(10) is vertically combined on a front end contacting with a train and a friction reducer(9) is installed on a lower part. |
