Abstract
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.
