Abstract: An illustrative example embodiment of an elevator rope sway damping assembly includes a plurality of sway dampers having a width and a length. An actuator device selectively causes movement of the sway dampers in a direction transverse to the length between a first position where the sway dampers are spaced apart by a first distance and a second, sway-damping position where the sway dampers are spaced apart by a second, shorter distance. The actuator device provides an indication when the sway dampers are in the first position.

Abstract: 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.

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.

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 base is configured to be selectively movable relative to the pivot axis. A plurality of door movement bumpers are supported on the at least one base. Selective movement of the at least one base relative to the pivot axis adjusts an alignment position of the door movement bumpers.

Abstract: An illustrative example embodiment of an elevator door assembly includes a door panel having at least one edge. A base is configured to be received adjacent the edge of the door panel. An astragal is configured to be at least partially received over the base such that the base holds the astragal in a selected position aligned with the edge of the door panel. The astragal is at least partially compressible for closing off an interface between the edge of the door panel and an adjacent surface.
