An elevator car door control system includes a clutch and an interlock assembly. The clutch may include a stationary base and a slidable base movably attached to the stationary base. The stationary base may be adapted for attachment to a car door of an elevator car. The interlock assembly may include a locking arm operatively connected to the slidable base of the clutch and moveable from a locked position preventing translation relative to the elevator car to an unlocked position. When the car door is in a closed position, a door opening sequence may commence causing the slidable base to move relative to the car door, but the car door will only open if the slidable base presses against an object, such as a roller on a hoistway door, in which case the locking arm of the interlock assembly moves from the locked to the unlocked position.

An illustrative example embodiment of an elevator system includes an elevator car situated for movement among a plurality of landings. The elevator car includes a car door and a door mover. A door interlock associated with a landing door at each of the landings is configured to couple the associated landing door with the car door. The door interlocks respectively include a lock switch. A controller is configured to: cause the elevator car to move to at least one of the landings; when the elevator car is at the at least one landing, cause the door mover to instigate movement of the door interlock sufficient to at least temporarily change a position of the lock switch; and locate a malfunctioning one of the lock switches at one of the landings based on the movement of the door interlock.

A system for controlling service access associated with an elevator car includes a divider configured to divide an elevator shaft into a plurality of service access zones; and a controller configured to control a locking state of at least one service access from inside the elevator car to the elevator shaft based on a service access zone of the plurality of service access zones at which the elevator car is located.

A landing floor door access system for an elevator system includes a door lock operably connected to a landing floor door, and a door lock controller operably connected to the door lock. The door lock controller is configured for non-contact communication with an access device such that communication between the access device and the door lock controller initiates a signal from the door lock controller to the door lock to deactivate the door lock. A method of accessing a hoistway of an elevator system, includes approaching a landing floor door of the elevator system, the landing floor door positioned at the hoistway, and initiating communication between an access device and a door lock of the landing floor door via non-contact interaction between the access device and the door lock. The door lock is deactivated via the non-contact interaction between the access device and the door lock.

Car doors hanging down via door hangers are disposed on a door rail that is disposed on a vertically-oriented frame disposed above an entrance of a car and extends along a width direction of the entrance of the car. One of a magnetic proximity switch and a target for detecting that the car doors are fully open and fully closed is disposed on a horizontal part extending from an upper end of the frame toward the entrance of the car. The remaining one of the magnetic proximity switch and the target is disposed on an extending part extending from each of the door hangers so as to be opposed in a vertical direction to the one of the magnetic proximity switch and the target for detection.

A lock for an elevator door, the lock being a wireless magnetic field induction current controllable lock.

A hoistway door locking system includes an elevator shaft. Also included is an elevator car disposed within the elevator shaft and moveable therein between a plurality of access openings located at a plurality of levels of the elevator shaft. Further included is a plurality of locking mechanisms, at least one of the plurality of locking mechanisms being located at each of the plurality of access openings, wherein each of the plurality of locking mechanisms is operable between a locked condition and an unlocked condition, and wherein only a single locking mechanism may be in the unlocked condition at a specific time, the unlocked condition occurring upon alignment of the elevator car and the respective access opening having the single locking mechanism.
