CAR DOOR LOCKING DEVICE

摘要

A control device for doors of an elevator system comprises a coupling system for coupling a car door with a landing door and operable to open and close the car door and the landing door at a landing position of the car. A car door locking mechanism locks the car door shut and permits the unlocking of the car door in response to the coupling system reaching an opening position. A blocking device blocks the coupling system from reaching the opening position when outside the landing position of the car.
