Abstract
An elevator car for an elevator installation may include at least one side wall having a doorway and an elevator car door. For opening and/or closing the doorway, the elevator car door can be moved at least partially parallel to the side wall on an outside of the side wall. In opening and/or closing, the elevator car door can be moved at least partially in a direction perpendicular to the side wall. In the closing process, the elevator car door can be at least partially sunk in the doorway. A coupling element may couple the elevator car door to a shaft door in at least one of opening or closing the elevator car door.
Claims16
An elevator car for an elevator installation, the elevator car comprising:
- a side wall having a doorway defined therein;
- an elevator car door,
- wherein for at least one of opening or closing the doorway, the elevator car door is movable at least partially parallel to the side wall on an outside of the side wall,
- wherein for at least one of opening or closing the doorway, the elevator car door is movable at least partially in a direction perpendicular to the side wall,
- wherein the elevator car door is configured to be at least partially sunk in the doorway when closing the elevator car door;
- and
- a coupling element disposed one of in, or on, the elevator car door and configured to,
- couple said elevator car door to a shaft door upon a movement of said elevator car door in a direction perpendicular to and towards the shaft door, during an opening of said doorway, and
- decouple said elevator car door from the shaft door upon a movement of said elevator car door in a direction perpendicular to and away from the shaft door during a closing of said doorway.
A method for closing a doorway in a side wall of an elevator car of an elevator installation, the method comprising:
- coupling an elevator car door to a moveable elevator shaft door;
- moving the coupled elevator car door and elevator shaft door together at least partially parallel to the side wall of the elevator car on an outside of the side wall in a direction of the doorway until the elevator car door overlaps with the doorway;
- moving the elevator car door at least partially perpendicularly to the side wall into the doorway and sinking at least part of the elevator car door into the doorway so as to be seated within a frame of the doorway thereby closing the doorway with the elevator car door;
- and
- de-coupling the elevator car door from the elevator shaft door by the at least partially perpendicular movement of the elevator car door into the frame of the doorway.
A method for opening a doorway in a side wall of an elevator car of an elevator installation, the method comprising:
- moving an elevator car door that is in a closed state sunk within the doorway in a direction at least partially perpendicular to the side wall and outwardly away from the elevator car, to a position outside of both the doorway and a plane spanned by the side wall;
- coupling the elevator car door to an elevator shaft door by said moving of the elevator car door at least partially perpendicularly to the sidewall;
- and
- moving the elevator car door and coupled elevator shaft door together at least partially parallel to the side wall of the elevator car on an outside of the side wall so that the elevator car door does not completely overlap with the doorway, thereby opening the doorway.
