Definitions

  • the invention relates to an elevator with an elevator car, a horizontally displaceable car door leaf, a horizontally displaceable shaft door panel and a coupling device for transmitting an opening movement or a closing movement of the car door leaf on the shaft door leaf, wherein the coupling device comprises a displaceable entrainment member, which is for coupling the car door leaf with the landing door wing is brought into contact with a counter element present on the shaft door wing, the interaction of the coupling device with the counter element causing the unlocking of a car door bolt. Furthermore, a method for actuating a car door bolt is the subject of the invention.
  • the invention relates to the problem of preferably allowing an opening movement of an elevator car door leaf when the elevator car is within allowable dislocations at the level of a floor.

  • the distance adjustment between the two driving skids takes place by a door drive unit fastened to the car door frame via a linearly acting drive means (for example by means of a belt drive), which also effects the closing and opening movements of the car door leaf.
  • the drive means engages on a pivot lever connected to one of the adjusting elements of the parallelogram on the car door leaf, that the adjusting elements are pivoted by the opening movement of the linearly acting drive means before the start of a door leaf opening movement in a position in which the Mit videkufen are brought to the counter elements thereby unlocking the landing door panel and forming said coupling between the car door panel and the corresponding landing door panel.
  • the adjusting elements are pivoted back into a position in which the Mitallekufen are spaced from the counter elements by the closing movement of the linearly acting drive means, so that the locking of the shaft door panel returns to its locking position.
  • EP 0 332 841 B1 also discloses a means for unlocking the bolt of a car door latch, which is to ensure that the car door is unlocked automatically only when the car door facing a shaft door of the elevator.

If a door opening command and a resulting spread of the Mit psychologykufen of the coupling mechanism, when the door of the elevator car does not face a shaft door, the Mit videkufen get as well as the Tastkufe not in contact with any of the counter elements on the shaft door leaves. The Tastkufe is therefore not moved against the Mit classmateskufe, and the cab door latch remains in its locked position. A sensor monitoring the position of the car door bolt additionally prevents the door drive motor from being switched on.
  • the illustrated coupling mechanism with Kabinenfentriegelung requires on one of the Mit supportivekufen a relative to this movable and parallel guided Tastkufe, which is associated with high material and manufacturing costs.

Furthermore, the object is achieved by a lift according to claim 15. Advantageous embodiments and further developments of the invention will become apparent from the dependent claims.
  • a coupling device attached to the car door leaf has at least one displaceable driving element which can be brought into contact with a counter element present on the shaft door leaf by means of a coupling movement.
  • a blocking effect of the car door lock is dependent on the interaction of the coupling device with the counter element, wherein a position of the driver element is uniquely associated with a corresponding position of the car door latch.
  • position of the driver element and “position of the car door bolt” are to be understood here in each case the relative position of the driver element or of the car door bolt with respect to the car door leaf, to which both the driver element and the car door latch are connected.
  • a defined position of the car door bolt relative to the car door leaf also corresponds to a defined position of the car door bolt relative to the bolt stop.

  • the position of the car door bolt relative to the car door leaf, and thus in the closed position of the car door leaf and the bolt stop should not be influenced by another element. In particular, therefore, a rigid coupling between the car door latch and the driver element is provided.

  • the driver element (21) during the coupling movement continues to move up to a defined coupling position. This situation occurs, for example, when a too large vertical displacement between cabin door sash and landing door wing is present, so that the driver element does not hit the counter element in its coupling movement.
  • the movement of the car door bolt is rigidly coupled via a lever system with the movement of the driver element.
  • the term "rigidly coupled” is to be understood here as meaning that there is a coupling between two components, which ensures that, in every possible situation, a movement of the one component in the coupling direction necessarily causes a movement of the second component in the coupling direction.
