Abstract

A climbing elevator system has an elevator shaft and an elevator car, a lifting platform, and a supporting device, wherein, in the course of different construction phases of a building, the lifting platform can be anchored at various positions within the elevator shaft. A protective roof is arranged above components of the lifting platform that are to be protected, such as a drive machine. The protective roof has a central roof structure and a peripheral flank structure that has flank walls fixed to the lateral edges of the central roof structure and project outwardly from the central roof structure at an angle with respect to the horizontal. Because of the inclined arrangement of the flank walls, the flank structure can better withstand falling objects and better protect components located underneath. Cantilevered edge regions of the flank walls can be supported on side walls of the elevator shaft.

First claim

The invention claimed is:

1. An elevator system comprising:
an elevator shaft; and
a protective roof arranged inside the elevator shaft, wherein the protective roof has a central roof structure extending in a horizontal plane and a peripheral flank structure extending around an entire periphery of the central roof structure, wherein the flank structure has flank walls fixed to the central roof structure and the flank walls project outwardly from the central roof structure at a predetermined angle oblique with respect to the horizontal plane, and the flank structure further includes corner structures connected to the flank walls and inclined at the oblique angle with respect to the horizontal plane.

2. The elevator system according to claim 1 wherein lower end regions of the flank walls are fixed to the central roof structure.

3. The elevator system according to claim 1 wherein the predetermined angle is between 20° and 70° to the horizontal plane.

4. The elevator system according to claim 1 wherein the flank walls are fixed to the central roof structure in a reversibly detachable manner.

5. The elevator system according to claim 1 wherein the flank walls are each fixed to the roof structure by a fixing structure, wherein the fixing structure allows each of the flank walls to be fixed detachably and at various positions at selected distances from an associated edge of the central roof structure.

6. The elevator system according to claim 5 wherein the fixing structure includes a reversibly releasable and attachable tongue and groove joint holding the flank walls in only one or two spatial directions when released and holding the flank walls in three spatial directions when attached.

7. The elevator system according to claim 1 wherein the flank walls are fixed to the central roof structure in a position and orientation wherein cantilevered edge regions of the flank walls, which are arranged opposite end regions of the flank walls that are fixed to the central roof structure, are distanced from side walls of the elevator shaft by less than 30 mm.

8. The elevator system according to claim 1 wherein the flank walls are fixed to the central roof structure in a position and orientation wherein cantilevered edge regions of the flank walls, which are arranged opposite end regions of the flank walls that are fixed to the central roof structure, rest against side walls of the elevator shaft.

9. The elevator system according to claim 1 wherein the corner structures each have two corner flank walls that are at an angle to one another and are fixed to one another along a common edge and are each arranged inclined at the oblique angle with respect to the horizontal plane.

10. The elevator system according to claim 9 wherein the corner structures are fixed to the central roof structure by a corner fixing structure, wherein the corner fixing structure allows the corner structures to be fixed detachably and at positions at various selected distances from an associated corner of the central roof structure.

11. The elevator system according to claim 10 wherein the corner fixing structure includes a reversibly releasable and attachable tongue and groove joint that holds the corner structure in only one or two spatial directions when released and holds the corner structure in three spatial directions when attached.

12. The elevator system according to claim 1 wherein the flank walls have a wall thickness of at least 3 mm.

13. The elevator system according to claim 1 wherein the flank walls are formed of a metal material or of a composite material provided with a metal layer.

14. The elevator system according to claim 1 further comprising:
an elevator car;
a lifting platform;
a supporting means;
wherein the elevator car is held by the supporting means and is displaceable within the elevator shaft by the supporting means;
wherein the supporting means is held on the lifting platform; and
wherein the protective roof is arranged above components of the lifting platform that are to be protected.

15. The elevator system according to claim 14 wherein one of the components is a drive machine arranged on the lifting platform for driving the supporting means.

16. The elevator system according to claim 14 wherein the lifting platform is adapted to be temporarily fixed at various selected positions within the elevator shaft.
