An elevator car door control system includes a clutch and an interlock assembly. The clutch may include a stationary base and a slidable base movably attached to the stationary base. The stationary base may be adapted for attachment to a car door of an elevator car. The interlock assembly may include a locking arm operatively connected to the slidable base of the clutch and moveable from a locked position preventing translation relative to the elevator car to an unlocked position. When the car door is in a closed position, a door opening sequence may commence causing the slidable base to move relative to the car door, but the car door will only open if the slidable base presses against an object, such as a roller on a hoistway door, in which case the locking arm of the interlock assembly moves from the locked to the unlocked position.

An illustrative example elevator door interlock includes a first base configured to be supported on a hoistway door component, The first base is situated to be selectively pivoted relative to the hoistway door component. A first bumper is supported on the first base such that pivotal movement of the first base changes a position of the first bumper relative to the hoistway door component. A second base is situated to be selectively moved relative to the hoistway door component. A second bumper is supported on the second base such that selective movement of the second base changes a position of the second bumper relative to the hoistway door component. A latch is situated for pivotal movement about a pivot axis relative to the first base between a door locking position and a released position.

A method of unlocking an elevator car door or an elevator car includes operating a door operator and moving a movable vane operably coupled to the door operator. If the elevator car is positioned within a landing door zone, the movable vane is moved into contact with an interlock roller. An engagement latch is rotated to disengage from an electrical contact in response to moving the movable vane into contact with the interlock roller.

An illustrative example method of positioning an elevator door interlock includes positioning an elevator car in a hoistway near the hoistway door so that at an elevator door coupler is aligned with the interlock, opening a door of the elevator car and the hoistway door, accessing an adjustment mechanism supporting the interlock from outside of the hoistway, and using the adjustment mechanism to adjust a position of the interlock relative to the hoistway door from outside the hoistway.

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.

Provided is a door lock operation member for elevator door lock device for operating an elevator door lock device, the elevator door lock device including an interlock and a car door lock, the interlock being configured to lock the movement of a landing door in the opening direction when the landing door is in a closed state, the car door lock being configured to lock the movement of a car door in the opening direction when the car door is in a closed state. The door lock operation member further includes a lock operation part configured to actuate both the interlock and the car door lock in association with movements of the car door in the opening direction and in the closing direction.
