An elevator car door interlock includes a first link assembly and a latch assembly. The first link assembly includes a first intermediate link and a first link. The first intermediate link is movably connected to a first sensing vane. The first link is pivotally connected to a baseplate. The first link has a first link first arm pivotally connected to the first intermediate link, and a first link second arm having a first link first connection that is pivotally connected to a second sensing vane. The latch assembly includes a lock member, a door latch, and a latch link. The door latch is pivotally connected to the baseplate and is arranged to selectively engage the lock member. The latch link extends between and is pivotally connected to the door latch and the first intermediate link.

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.

Elevator car door systems are provided. The systems include an elevator car having a car door and a movable car door coupling attached to the car and arranged to control operation of the car door. A mounting bracket is attached to the car, a first blade is attached to the mounting bracket, a second blade is attached to the mounting bracket, and a deterrent is attached to the mounting bracket. The first and second blades are operable a landing door coupling to operate the car door. A portion of the movable car door coupling is arranged to contact a ceiling of an elevator shaft during an overrun event when and move a part of the movable car door coupling relative to the car, and when the portion is not in contact with the ceiling, a biasing element urges the portion toward a normal position.

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.

A mechanical hoistway access control device for an elevator landing door includes a first and a second base plates mounted on the hoistway side of a landing door panel and arranged in parallel with one another, a slider slidably arranged between the first and second base plates and configured to move in conjunction with a car door and configured to protrude out from a door closing side end of the landing door by a first elastic member to take an extended position when the landing door is opened with no elevator car at the landing, and a latch attached to the landing door and configured to engage with the slider to keep the slider in the extended position once the slider protrudes out from the door closing side end of the landing door.

An elevator car door interlock for unlocking an elevator car door of an elevator car is provided including a lock member (54) including an electrical contact (72). A rotatable link arm (58) has a sensing mechanism (52, 62) configured to detect a position of the elevator car door. An engagement latch (64) is pivotally mounted to the rotatable link arm. The engagement latch is engaged with the electrical contact when the elevator car door is locked. The engagement latch is rotated out of engagement with the electrical contact when the elevator car door is unlocked.

A lock assembly for an elevator car door is provided including a car mechanism configured to move from a first position to a second position upon detection of a known condition. A contactor is mounted adjacent a lower portion of the elevator car door and is operably coupled to the car door mechanism. The contact is movable in response to movement of the car door mechanism to lock and unlock a portion of the elevator car door.
