Abstract
PURPOSE: To provide an arrangement for elevator door, in which there is provided an actuator that comes into contact with a contact plate on the hatch door at the initial door opening motion of the cage door and resets the locking means of cage, so that lock of the cage door is reset only when the cage is stopped at the correct stop position of floors, thereby preventing such an accident that passengers drop into the hoistway from the cage door.
CONSTITUTION: Safety system for elevator door of this invention comprises hatch door 17, cage door 2, contact plate 19 provided on the hatch door 17 extended in normal cage landing range, locking means 5 provided on cage 1 for resetting lock of the cage door when necessary, and actuator 3 provided on cage door 2 in freely movable manner, which comes into contact with contact plate 19 with initial cage door opening motion and is moved thereby before opening of the cage door is prevented by the locking means 5, thereby resetting the lock of locking means 5. With such an arrangement, lock of the cage door is reset only contact plate 19 and actuator 3 are hold in contact with each other. Therefore, such an accident that is possible caused when the cage door is opened manually by passengers at the time when the cage is stopped by some trouble of elevator system can be prevented with high reliability.
