摘要： 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.

摘要： Elevator door coupling systems are described. The systems include a car door lock having a coupling element and a lock element, the lock element operably connected to a latch for locking the car door lock and a landing door lock having a movable plate, a first contact element mounted to the movable plate and configured to engage with the coupling element and a second contact element configured to engage with the lock element. In operation, the coupling element is operable to apply force to the first contact element and cause the movable plate to rotate and as the movable plate rotates, the second contact element applies force to the lock element to urge the latch from a locked position to an unlocked position.

摘要： 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.

摘要： A method can be used to position a car door and a landing-stop door in a synchronized manner at a landing stop in an elevator shaft of an elevator system. The car door may be configured as a guide door, and the landing-stop door may be configured as a follower door. The method may involve bringing an elevator car close to the landing stop, upon entry of the car door into an unlock zone sensing a presence signal of the follower door by way of a presence sensor of the guide door, actuating the guide-door drive by way of the guide controller and executing an opening movement of the guide door, providing movement information of the guide door, and actuating the follower-door drive of the follower door.

摘要： Elevator systems and methods are provided. The systems include an elevator car movable within an elevator shaft, the elevator car includes an elevator car door interlock device operable to open and close elevator car doors, a plurality of landing doors located at respective landings along the elevator shaft, wherein each landing door includes a landing door interlock device operable to open and close a respective landing door, wherein each landing door interlock device is engageable by the elevator car door interlock device to enable operation of the elevator car doors and the respective landing door simultaneously. An elevator component inspection system is configured with a detector located on the top of the elevator car and arranged to monitor the interlock devices, wherein the detector obtains inspection data associated with the elevator car door interlock device and the plurality of landing door interlock devices.

摘要： 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.

摘要： In an elevator car door apparatus, a locking member is disposed on a blade-carrying car door, and is displaceable between an unlocked position and a locked position interdependently with movement of a doorstop-side blade. A guiding portion is disposed on the locking member. A guiding cam is disposed outside the blade-carrying car door. When the car is positioned outside an appropriate floor alignment position, the blade-carrying car door moves in an opening direction, the guiding portion moves along the guiding cam, the locking member displaces to the locked position, and the doorstop-side blade also displaces to a locking accommodating position, the locking member catches in a fixed latch, and movement of the blade-carrying car door in the opening direction is prevented.

摘要： An elevator system includes a hoistway and an elevator car positioned in the hoistway and configured to travel along the hoistway. The elevator car includes an elevator car door. A door operator assembly is fixed in the hoistway at a landing floor and includes a sensor to sense presence of the elevator car at the landing floor; and a door operator mechanism to open both the elevator car door and a landing floor door when the sensor senses presence of the elevator car at the landing floor. A light source may be fixed at the hoistway and a light transmitter is positioned at the elevator car to gather light from the light source and output the light into an interior of the elevator car. A ventilation system may be fixed at the hoistway and is interactive with the elevator car to condition an interior of the elevator car.
