Patent ID: 8607937

Claim:
An elevator with an elevator car having car door with a horizontally moveable car door leaf, a horizontally moveable shaft door leaf, a car door locking mechanism having a car door bolt and a bolt stop as well as a coupling device which is connected to the car door leaf for transmitting an opening movement or a closing movement from the car door leaf to the shaft door leaf, comprising: the coupling device including a moveable entraining element which is brought into contact, by a coupling movement, with an opposite element arranged on the shaft door leaf, and a locking effect of the car door locking mechanism is dependent on an interaction of the coupling device with the opposite element; and the car door bolt being formed as a slide which is slidably movable in a bolt guide provided on the car door leaf, a movement of the car door bolt being rigidly coupled to the movement of the entraining element, and the car door bolt interacting with the bolt stop which is fixed to the car door, wherein the car door bolt blocks an opening movement of the car door leaf by contact with the bolt stop when the entraining element is located in a through-travel position at a distance from the opposite element, the car door bolt permits the opening movement of the car door leaf when the entraining element is stopped in a defined coupling position by the opposite element, the car door bolt blocks the opening movement of the car door leaf by contact with the bolt stop when the entraining element moves further than up to the defined coupling position during the coupling movement, and wherein the car door bolt has a recess which permits the car door bolt and the car door leaf to carry out the opening movement past the bolt stop when the coupling movement of the entraining element has been stopped by the opposite element in the defined coupling position.
