    (54) Arrangement for the locking of the door of an elevator car


    (57) The invention concerns an arrangement for the locking of the door of an elevator car, comprising a lock that latches the door (1), guide surfaces (2) provided at the landings, an actuating lever 7 controlled by the guide surfaces, and a transmission means connecting the lock and the actuating lever. According to the invention, the lock­ing arrangement comprises an electrically operated actua­tor (5) serving to shift the fulcrum (17) of the actuating lever (7) in such a way that the part of the actuating lever which uses the guide surface as a bearing will remain at a distance from it, and a counter device (6) serving to move the fulcrum (17) in the opposite direction so that when the elevator car is at a landing, the actuating lever, leaning against the guide surface, will unlatch the lock.
