Abstract
In the procedure for closing an elevator landing door (3,4), the landing door is coupled with the car door (1,2) by a door coupler, and the car door is moved by an actuator provided in conjunction with the elevator car. During the initial phase of the closing movement, the car door and landing door are moved at the same speed, but towards the end of the closing movement the landing door (3,4) is caused to move faster than the car door (1,2). Based on control by the car door movement, the coupling elements (5,6) of the door coupler are moved in the direction of the car door movement.
