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.

A method of unlocking an elevator car door or an elevator car is provided including operating a door operator. A link arm of a car door interlock operably coupled to the door operator is rotated. If the elevator car is positioned within a landing door zone, an engagement link coupled to the link arm is configured to pivot relative to the link arm to disengage from an electrical contact. If the elevator car is not positioned within a landing door zone, the engagement link does not pivot relative to the link arm and remains engaged with the electrical contact.

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 door interlock of the present invention includes an engaged part and an engaging part configured to lock a door in a door closed state. The engaging part includes: a locking member; a mounting member mounted to the locking member; a sim member inserted into a slit; a first fixing member; and a second fixing member. The first fixing member is configured to be inserted into a first lock through hole, a first sim through hole, and a mount through hole, thereby fixing the mounting member and the sim member to the locking member. The second fixing member is configured to be inserted into a second lock through hole and a second sim through hole, thereby fixing the sim member to the locking member.

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 coupling bumper is situated for movement with the latch between the door locking and released positions. The coupling bumper is selectively moved relative to the pivot axis into an alignment position where the coupling bumper is positioned to cooperate with a door coupler. At least one stationary support is situated to contact the coupling bumper when the latch is in the released position where the stationary support bears a load associated with moving an associated door.
