Abstract: An exemplary device for preventing travel of an elevator car when a car door is open includes a receiver that remains in a fixed position relative to a hoistway wall. A stop member moves responsive to the car door moving toward an open position such that the stop member engages the receiver to prevent movement of the elevator car when the door is open.
