Abstract

An elevator system may include at least two elevator shafts along with an elevator car with a cab and a chassis device. The cab may be mounted rotatably about a horizontal rotational axis relative to the chassis device. A vertically extending rail, along which the elevator car is movable, may be disposed in each elevator shaft. Each of the rails may include a rotatable segment such that the rotatable segments are alignable with respect to one another so that the elevator car is movable along the segments between the elevator shafts. A first device may lock the cab relative to the chassis device, and a second device may hold the cab relative to the elevator shafts.

First claim

What is claimed is:

1. An elevator system comprising:
at least two elevator shafts;
an elevator car with a cab and a chassis device, wherein the cab is mounted so as to be rotatable about a horizontal rotational axis relative to the chassis device;
a vertically extending rail disposed in each of the at least two elevator shafts, wherein the elevator car is movable along the vertically extending rails, wherein each of the vertically extending rails comprises a rotatable segment, with the rotatable segments being alignable with respect to one another such that the elevator car is movable between the at least two elevator shafts along the rotatable segments;
a first device for locking the cab of the elevator car relative to the chassis device; and
a second device for holding the cab in position relative to the at least two elevator shafts.

2. The elevator system of claim 1 wherein the first device is configured to lock the cab of the elevator car in a first position relative to the chassis device and in a second position relative to the chassis device.

3. The elevator system of claim 2 wherein the first position of the cab relative to the chassis device enables mobility along one of the at least two elevator shafts, wherein the second position of the cab relative to the chassis device enables mobility between the at least two elevator shafts.

4. The elevator system of claim 2 wherein the first device comprises a first blocking element and a corresponding first engagement element, wherein the first blocking element is movable between a locking position and a release position.

5. The elevator system of claim 4 wherein the first blocking element is a locking bar and the corresponding first engagement element comprises a first corresponding receiving means and a second corresponding receiving means such that the cab is lockable relative to the chassis device in the first position by engaging the locking bar with the first corresponding receiving means, and such that the cab is lockable relative to the chassis device in the second position by engaging the locking bar with the second corresponding receiving means.

6. The elevator system of claim 4 wherein the first blocking element is a brake shoe that lies against the corresponding first engagement element in the locking position, wherein the brake shoe comprises a braking surface such that the cab is locked relative to the chassis device by way of frictional locking.

7. The elevator system of claim 4 wherein the first blocking element is connected to the chassis device and the corresponding first engagement element is connected to the cab.

8. The elevator system of claim 1 wherein the second device comprises a second blocking element and a corresponding second engagement element, wherein the second blocking element is movable between a locking position and a release position.

9. The elevator system of claim 8 wherein the second blocking element is connected to one of the at least two elevator shafts.

10. The elevator system of claim 8 wherein the second blocking element is a locking bar that is configured to engage with the corresponding second engagement element, which is configured as an indentation, to block rotation of the cab about the horizontal rotational axis in both directions of rotation.

11. The elevator system of claim 8 wherein the second device blocks rotation of the cab about the horizontal rotational axis in only one direction of rotation.

12. The elevator system of claim 11 wherein the second blocking element is an end stop that interacts with the corresponding second engagement element, wherein the end stop comprises a stop surface for blocking rotation of the cab about the horizontal rotational axis in the only one direction of rotation.

13. The elevator system of claim 1 wherein the second device comprises a rotary drive for rotating the cab about the horizontal rotational axis relative to the chassis device, wherein when the chassis device is rotated about the horizontal rotational axis the rotary drive is configured to counter rotate the cab to hold the cab in position relative to the at least two elevator shafts.
