ABSTRACT:
An apparatus for locking the door of an elevator car includes a lock (12) that locks the car door, a guide surface (9) in the elevator shaft at each landing and a linkage (6) operating the lock (12). The linkage includes an operating lever (17) which, when at a landing, presses against the guide surface (9) via a roller. The lever is pivotally attached to the linkage (6) by a movable pivot (20). When the door is reaching the closed position, a coupling element (2) transmits motion of the door to the linkage (6) to operate the lock (12) using the driving power of the door actuating mechanism.
