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.

An elevator door interlock, comprising:
- a latch situated for pivotal movement about a pivot axis between a door locking position and a released position;
- at least one coupling bumper 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;
- and
- at least one stationary support 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.
A method of installing an elevator door interlock that includes a latch that is configured to pivot about a pivot axis and at least one coupling bumper, the method comprising:
- positioning the latch in a selected position relative to a hoistway door component;
- adjusting a position of the at least one coupling bumper relative to the latch by moving a base supporting the at least one coupling bumper relative to the hoistway door component without moving the pivot axis of the latch;
- and
- securing the base in a selected position that secures at least the first one of the bumpers in a desired position relative to the hoistway door component when the latch is in a locking position.
