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 base is configured to be selectively movable relative to the pivot axis. A plurality of door movement bumpers are supported on the at least one base. Selective movement of the at least one base relative to the pivot axis adjusts an alignment position of the door movement bumpers.
