Abstract

A cage-door/shaft-door coupling of an elevator installation includes at least one pivot lever pivotably mounted at an axis of rotation associated therewith, wherein the pivot lever has a joint point and wherein the cage-door/shaft-door coupling further includes a first entrainer runner, which is mounted at the joint point, wherein the pivot lever includes a base member and a setting element fastened to the base member by way of a settable fixing means and wherein the settable fixing means enables a change in the spacing between the joint point and the associated axis of rotation.

First claim

I claim:

1. A coupling for an elevator cage door and an elevator shaft door, the coupling comprising:
a first pivot lever pivotably mounted at a first axis of rotation, the first pivot lever comprising a first joint point, a first base member and a first setting element fastened to the first base member by a first settable fixing member, the first settable fixing member enabling a change in a spacing between the first joint point and the first axis of rotation and a fixing of the spacing between the first joint point and the first axis of rotation during a coupling process of the elevator cage door;
a second pivot lever pivotably mounted at a second axis of rotation, the second pivot lever comprising a second joint point, the first and second axes of rotation and the first and second joint points defining corners of a parallelogram in a plane extending at right angles to the first and second axes of rotation; and
a first entrainer runner mounted at the first and second joint points.

2. The coupling of claim 1 , the first axis of rotation being associated with the first base member, and the first joint point being associated with the first setting element.

3. The coupling of claim 1 , the second pivot lever further comprising a second base member and a second setting element fastened to the second base member by a second settable fixing member.

4. The coupling of claim 3 , further comprising a second entrainer runner.

5. The coupling of claim 4 , the second entrainer runner being fixable to a door and parallel to the first entrainer runner.

6. The coupling of claim 1 , the first settable fixing member comprising a slot or hole in the first setting element.

7. The coupling of claim 6 , the first setting element comprising a toothing.

8. The coupling of claim 1 , the first settable fixing member comprising a slot or hole in the first base member.

9. The coupling of claim 8 , the first base member comprising a toothing.

10. The coupling of claim 1 , the first settable fixing member comprising a screw connection of the first setting element.

11. The coupling of claim 1 , the first settable fixing member comprising a screw connection of the first base member.

12. The coupling of claim 1 , the first entrainer runner comprising entrainer runner elements.

13. The coupling of claim 12 , the entrainer runner elements comprising:
a first entrainer runner element, the first entrainer runner element comprising an elongate section;
a second entrainer runner element, the second entrainer runner element comprising a first runner terminal; and
a third entrainer runner element, the third entrainer runner element comprising a second runner terminal, the first and second runner terminals being fastened to the elongate section.

14. An elevator installation, comprising:
an elevator cage door;
an elevator shaft door; and
a coupling for the elevator cage door and the elevator shaft door, the coupling comprising,
a first pivot lever pivotably mounted at a first axis of rotation, the first pivot lever comprising a first joint point, a first base member and a first setting element fastened to the first base member by a first settable fixing member, the first settable fixing member enabling a change in a spacing between the first joint point and the first axis of rotation and a fixing of the spacing between the first joint point and the first axis of rotation during a coupling process of the elevator cage door,
a second pivot lever pivotably mounted at a second axis of rotation, the second pivot lever comprising a second joint point, the first and second axes of rotation and the first and second joint points defining corners of a parallelogram in a plane extending at right angles to the first and second axes of rotation, and
a first entrainer runner mounted at the first and second joint points.
