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.
Claims20
An elevator door interlock, comprising:
- a latch situated for pivotal movement about a pivot axis between a door locking position and a released position;
- at least one base that is configured to be selectively movable relative to the pivot axis;
- and
- a plurality of door movement bumpers supported on the at least one base, wherein selective movement of the at least one base relative to the pivot axis adjusts an alignment position of the door movement bumpers.
A method of installing an elevator door interlock that includes a latch that is configured to pivot about a pivot axis and two bumpers, the method comprising:
- positioning the latch in a selected position relative to a hoistway door component;
- adjusting a position of at least a first one of the bumpers relative to the latch by moving a base supporting at least the first one of the bumpers relative to the hoistway door component without moving the pivot axis of the latch;
- and
- securing the base in a selected position that secures at least the first one of the bumpers in a desired position relative to the hoistway door component.
An elevator door interlock, comprising:
- a latch configured for pivotal movement about a pivot axis between a door locking position and a released position;
- at least one door movement bumper situated to be contacted by a door coupler component for moving an associated hoistway door;
- and
- a latch bumper supported for movement with the latch between the locking and released positions, the latch bumper being moveable between a first position corresponding to the latch being in the locking position and a second position corresponding to the latch being in the released position, the latch bumper second position being situated relative to the at least one door movement bumper such that the door movement bumper carries any load associated with the door coupler component moving the associated hoistway door and the latch bumper does not carry any of the load associated with moving the associated hoistway door.
