ABSTRACT:
A clutch couples a car door of an elevator car with a landing door of an elevator system, wherein the car door is movable with respect to the elevator car by a first actuator. The clutch includes at least one coupling element and a second actuator. The coupling element is movable with respect to the car door between a first position and a second position by the second actuator such that the coupling element engages with the landing door when the elevator car is within a landing zone and the coupling element is moved towards the second position, thereby establishing the coupling of the car door with the landing door. The second actuator is a linear motor.
