ABSTRACT OF THE DISCLOSURE A locking mechanism, for the doors of an elevator car, which is disabled when the car is within a short distance from a landing but which otherwise permits the doors to be opened by an amount insufficient for a passenger to exit from the car and then locks the doors with respect to further opening movement. In the preferred form, a door carries a notched plate, and a latch bolt on a part of the car which is stationary relative to the door is controlled by a movable strip associated with the clutch mechanism on a car which opens and closes the hoistway doors at which the car stops, so that the bolt will enter the notch of the plate when the car is away from a landing and the doors are partially opened.
