Abstract: An illustrative example elevator door interlock includes a latch situated for pivotal movement about a pivot axis between a door locking position and a released position. At least one coupling bumper is situated for movement with the latch between the door locking and released positions. The coupling bumper is selectively moved relative to the pivot axis into an alignment position where the coupling bumper is positioned to cooperate with a door coupler. At least one stationary support is situated to contact the coupling bumper when the latch is in the released position where the stationary support bears a load associated with moving an associated door.

Abstract: 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.

Abstract: 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.
