Abstract

An elevator system, including at least one first guide rail, which is oriented in a first, in particular vertical, direction, at least one second guide rail, which is oriented in a second, in particular horizontal, direction, a plurality of rotatable rail segments, wherein at least one thereof is transferable between an orientation in the first direction and an orientation in the second direction, at least one elevator cab, which is transportable along the guide rails and which, via the rotatable rail segments, is transferable between the different guide rails, at least one third guide rail, which is oriented in a third, in particular horizontal, direction, and wherein at least one of the rotatable rail segments is transferable between an orientation in the first or second direction into an orientation in the third direction.

First claim

What is claimed is:

1. An elevator system, comprising:
a first guide rail oriented in a first direction,
a second guide rail oriented in a second direction,
a plurality of rotatable rail segments, wherein at least one of the plurality of rotatable rail segments is configured to transfer between an orientation in the first direction and an orientation in the second direction,
an elevator cab configured to move along the guide rails and which, via the plurality of rotatable rail segments, is configured to transfer between the first and second guide rails, and
a third guide rail oriented in a third direction,
wherein at least one of the plurality of rotatable rail segments is configured to transfer between an orientation in the first or second direction into an orientation in the third direction.

2. The elevator system as claimed in claim 1 , wherein the three directions do not stand parallel to one another.

3. The elevator system as claimed in claim 1 , wherein the three directions are oriented orthogonally to one another.

4. The elevator system of claim 1 , wherein one of the plurality of rotatable rail segments is a multidimensionally rotatable rail segment, which is configured to transfer between an orientation in the first direction, an orientation in the second direction and an orientation in the third direction.

5. The elevator system of claim 4 , wherein the multidimensionally rotatable rail segment is formed by an arrangement of one of the plurality of rotatable rail segments within another of the plurality of rotatable rail segments.

6. The elevator system of claim 4 , wherein the multidimensionally rotatable rail segment is formed by an arrangement of a first rotatable rail segment within a second rotatable rail segment or an arrangement of the second rotatable rail segment within the first rotatable rail segment.

7. The elevator system of claim 6 , wherein the first rotatable rail segment is rotatable about a first rotational axis, which stands perpendicular to a plane which is spanned by the first and the second guide rail.

8. The elevator system of claim 7 , wherein the second rotatable rail segment is rotatable about a second rotational axis, which stands perpendicular to a plane which is spanned by the second and the third guide rail.

9. The elevator system of claim 6 , wherein at least one of the plurality of rotatable rail segments is assigned at least one stator unit of a linear motor, wherein the stator unit is pivotable with the at least one of the plurality of rotatable rail segments.

10. The elevator system of claim 9 , wherein the at least one of the plurality of rotatable rail segments is the second rotatable rail segment.

11. The elevator system of claim 6 , wherein at least one of the rotatable rail segments is assigned at least one stator unit of a linear motor, wherein the stator unit is not pivotable with the at least one of the plurality of rotatable rail segments.

12. The elevator system of claim 11 , wherein the at least one of the rotatable rail segments is the second rotatable rail segment.

13. The elevator system of claim 11 , wherein the stator unit is mounted in a rotationally secure manner in the elevator shaft of the elevator system.

14. The elevator system of claim 1 , wherein the first direction is vertical, the second direction is horizontal, and the third direction is horizontal.

15. The elevator system of claim 1 , wherein the elevator cab is guided on the guide rails via a backpack mounting.
