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.

An illustrative example embodiment of an elevator door lock includes a latch that is moveable between a locking position and a released position. The latch includes a locking surface configured to engage a stop when the latch is in the locking position. A magnet is situated to magnetically attract a portion of the latch to selectively move the latch from the locking position into the released position.

An illustrative example elevator door interlock includes a base, a plurality of interlock bumpers supported on the base, and a latch supported on the base for movement relative to the base between a door locking position and a released position. The plurality of interlock bumpers are supported on the base with a gap between the plurality of interlock bumpers. Each of the interlock bumpers includes a contact surface configured to contact at least one vane supported on an elevator car door. Each of the interlock bumpers remains rotationally fixed relative to the base. The latch includes a latch bumper that is situated relative to the gap such that the at least one vane contacts the latch bumper and urges the latch into the released position when the at least one vane is at least partially in the gap.

Provided is a door lock operation member for elevator door lock device for operating an elevator door lock device, the elevator door lock device including an interlock and a car door lock, the interlock being configured to lock the movement of a landing door in the opening direction when the landing door is in a closed state, the car door lock being configured to lock the movement of a car door in the opening direction when the car door is in a closed state. The door lock operation member further includes a lock operation part configured to actuate both the interlock and the car door lock in association with movements of the car door in the opening direction and in the closing direction.

A method of unlocking an elevator car door or an elevator car is provided including operating a door operator. A link arm of a car door interlock operably coupled to the door operator is rotated. If the elevator car is positioned within a landing door zone, an engagement link coupled to the link arm is configured to pivot relative to the link arm to disengage from an electrical contact. If the elevator car is not positioned within a landing door zone, the engagement link does not pivot relative to the link arm and remains engaged with the electrical contact.

An illustrative example elevator door interlock includes a first base configured to be supported on a hoistway door component, The first base is situated to be selectively pivoted relative to the hoistway door component. A first bumper is supported on the first base such that pivotal movement of the first base changes a position of the first bumper relative to the hoistway door component. A second base is situated to be selectively moved relative to the hoistway door component. A second bumper is supported on the second base such that selective movement of the second base changes a position of the second bumper relative to the hoistway door component. A latch is situated for pivotal movement about a pivot axis relative to the first base between a door locking position and a released position.
