  • Patent number: 11577936
    Abstract: An elevator car including: a door; and an apron movable between a deployed position and a retracted position; wherein in the deployed position the apron hangs below the door; wherein in the retracted position the apron is vertically overlapped with the door; and wherein in the retracted position the apron is engaged with the door such that it is movable sideways together with the door. As the apron is displaced upwards relative to the elevator car it will block the doorway. However, as the apron is engaged with the door in the retracted position, opening the door also moves the apron out of the way of the doorway so that the apron does not hinder passengers from using the elevator car.

  • Patent number: 11365094
    Abstract: A device for limiting sway in a travelling cable (6) in an elevator system is provided. The device comprises: a channel extending in a first direction for receiving the travelling cable (6) therein, wherein the channel is configured to be mounted in an elevator hoistway (2) such that the first direction corresponds to a direction of motion of an elevator car (4) within the hoistway (2); and an element (20) configured to move in the first direction along an open side of the channel simultaneously with an elevator car (4) and to push the travelling cable (6) into the channel when the element (20) moves along the open side thereof.
