  • Patent number: 11235952
    Abstract: Elevator systems are provided. The elevator systems include an elevator car movable along an elevator shaft having a pit floor and a shaft top, the elevator car having a car door lock arranged to enable opening of doors by a landing door lock mechanism when the elevator car is located at a landing and an elevator safety system. The elevator safety system includes a car door lock securing device arranged to prevent manual opening of the elevator car doors when in a first state and permits opening of the elevator car doors when in a second state and a car apron affixed to the car door sill and operable from a stowed state to a deployed state, wherein when the car apron transitions from the stowed state to the deployed state, the car door lock securing device is transitioned from the first state to the second state.

  • Patent number: 10968075
    Abstract: An elevator system (10) includes a hoistway (14) having a plurality of landing floors (34) each landing floor (34) having a landing floor door (36). An elevator car (12) is positioned in and drivable along the hoistway (14). A controller (38) restricts operation of the landing floor doors (36) based on a position of the elevator car (12) along the hoistway (14). A method of operating an elevator system (10) includes driving an elevator car (12) along a hoistway (14) of the elevator system (10) and determining a position of the elevator car (12) in the hoistway (14). Operation of a plurality of hoistway landing floor doors (36) is controlled based on the position of the elevator car (12) in the hoistway (14).

  • Patent number: 10914097
    Abstract: A landing door locking mechanism of an elevator system includes a body housing key-engagement elements and having a first end and a second end, the key-engagement elements located at the first end and a keyway structure, wherein in a first position the first end of the body is exposed such that a key may be inserted into a keyway of the keyway structure and interact with the key-engagement elements. A biasing mechanism is configured to bias a moveable portion of the body toward a second position, wherein in the second position a key cannot interact with the key-engagement elements and a solenoid is configured to apply a force on the moveable portion of the body when the solenoid is energized such that the moveable portion of the body is moved from the second position to the first position.
