SAFE FOOTBOARD SYSTEM TO BE AUTOMATICALLY FOLDED BY INTERLOCKING WITH THE OPENING AND CLOSING OF A DOOR WITHOUT POWER OR A CONTROL UNIT

摘要

PURPOSE: A safe footboard system interlocking with a door is provided to prevent accidents generated when passengers get on or off a train by installing a safe footboard between the platform and the train and to restrict a wrong operation by operating the safe footboard without power or a control unit. CONSTITUTION: A footboard unit(11) is composed of a square footboard(13) having an operating groove(12) on the rear side; side walls(14) protruded at both sides of the operating groove of the footboard; and a fixed sprocket(15) settled in the side walls. An operating plate unit(20) comprises an operating plate(21) positioned in the operating groove formed on the footboard of the footboard unit; a guide bar(22) of which one side is connected to the lower end of the operating plate and the other side is linked with the footboard; and an elastic member(23) inserted into the outer peripheral surface of the guide bar and settled at the end of the footboard. A chain unit comprises an operating chain(31) of which one end is fixed at both upper ends of the operating plate and connected to the fixed sprocket of the side wall and the other end is coupled with a wire(32); a moving chain(33) linked to the other end of the wire connected with the operating chain; and a guide member(34) for fixing the position of the moving chain. An operating unit lifts up and down the chain unit according to the opening and closing of a train door.
