LOCKING SYSTEM FOR CABIN DOOR

The invention relates to a locking system for locking and unlocking a cabin door of a lift cabin (11) of a lift system (I 0) in which lift system (JO) the lift cabin (II) can travel along a lift track having stopping points and associated stopping point zones. The locking system comprises a lock mechanism (28) that can be brought into a locking position and an unlocking position, wherein the cabin door in the locking position of the lock mechanism (28) is immobilized in the closed position and can be opened in the unlocking position of the lock mechanism (28), an actuator (16), by which the locking mechanism (28) can be brought either into the locking position of the locking mechanism or into the unlocking position of the locking mechanism, and a control device (22) which causes the actuator (16) to bring the locking mechanism (28) into the unlocking position of the locking mechanism when at least the condition that the lift cabin ( 11) is located in the region of a stopping point zone is met. The locking system is characterized in that the lift system (10) comprises a position detecting unit (27), which continuously detects the position of the lift cabin ( 11) relative to the lift track and communicates the position to the control device (22), and the control device (22), which continuously detects whether the condition that the lift cabin ( 11) is located in the region of a stopping point zone is met by comparing the position of the lift cabin ( 11) communicated by the position detecting unit (27) to stored position limit values of the stopping point zones.
