Abstract: 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.

Abstract: An illustrative example elevator door interlock includes at least one coupling roller supported on a base. A lock is configured to move relative to the base and the at least one coupling roller between a locking position and an unlocked position. An unlocking roller supported on the lock is situated to be moved by a vane of an elevator door coupler to move the lock into the unlocked position prior to the vane contacting the coupling roller. The elevator door interlock is compatible with a clamping type elevator door coupler and an expanding type elevator door coupler. The coupling roller is situated to be received between two vanes of the clamping type elevator door coupler or received against one of two vanes of the expanding type elevator door coupler.

Abstract: An illustrative example elevator system includes at least one elevator car that is moveable along a hoistway. An elevator controller is configured to respond to a communication from a portable device indicating a desire for the at least one elevator car to be placed in a maintenance mode and indicating a location of desired hoistway access. The controller automatically moves the elevator car to a determined positon based on the communication. That position corresponds to the location of the desired hoistway access. The controller performs at least one automated procedure to place the elevator car in the maintenance mode. The controller provides an indication to the portable device that the elevator car is in the determined position and that the automated procedure has been completed.

Abstract: 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.

Abstract: 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.
