Abstract

An elevator system includes a lifting platform for securing at a plurality of securing positions in an elevator shaft and at least one guide rail for vertically guiding an elevator car in the elevator shaft. The lifting platform has a protective roof that protects the lifting platform against falling objects, wherein the protective roof has a rail opening, through which the guide rail extends, and wherein the protective roof has a cover covering the rail opening, the cover having a cover opening through which the guide rail extends.

Claims

1-14. -14. (canceled)

15. An elevator system comprising:

a lifting platform adapted to be fastened to each of a plurality of fastening positions in an elevator shaft;

at least one guide rail for vertically guiding an elevator car in the elevator shaft, wherein the guide rail is fastened to a lateral wall of the elevator shaft by a rail clamp;

wherein the lifting platform has a protective roof that protects the lifting platform against falling objects in the elevator shaft;

wherein the protective roof has a rail opening through which the guide rail extends, wherein a cross section of the rail clamp can be guided through the cross section of the rail opening; and

wherein the protective roof has a cover covering the rail opening, the cover having a cover opening through which the guide rail extends.

16. The elevator system according to claim 15 wherein the cover opening has a shape that corresponds to a cross section of the guide rail.

17. The elevator system according to claim 15 wherein the cover opening and a cross section of the guide rail are T-shaped.

18. The elevator system according to claim 15 wherein a gap having a maximum width of 30 mm is present between the cover opening and the guide rail extending through the cover opening.

19. The elevator system according to claim 15 wherein the cover is formed of at least two cover parts.

20. The elevator system according to claim 19 wherein the cover opening is formed in only one of the cover parts, or wherein the cover opening is formed by both of the cover parts.

21. The elevator system according to claim 15 wherein the cover is fastened to the protective roof by hinges.

22. The elevator system according to claim 15 wherein the cover is arranged on an edge of the protective roof and the cover or cover parts of the cover are pivotable upwards about a hinge axis at least one of in parallel with the edge and orthogonally with respect to the edge.

23. The elevator system according to claim 15 wherein the protective roof includes a central roof construction that extends horizontally, and wherein the cover is arranged at least in part over the central roof construction.

24. The elevator system according to claim 15 wherein the protective roof has a peripheral flank construction that extends diagonally with respect to a horizontal line, and wherein the cover is arranged at least in part over the peripheral flank construction.

25. The elevator system according to claim 15 wherein the cover is positioned on a cover box that is fastened on the protective roof.

26. The elevator system according to claim 25 wherein the cover box extends to an edge of the protective roof.

27. The elevator system according to claim 25 wherein the cover box is fastened on a central roof construction of the protective roof that extends horizontally, and a peripheral flank construction of the protective roof that extends diagonally with respect to a horizontal line is fastened to a side of the cover box.

28. The elevator system according to claim 15 further comprising:

the elevator car; and

a suspension means wherein the elevator car is held by the suspension means and can be moved inside the elevator shaft along the at least one guide rail by the suspension means, wherein the suspension means is held on the lifting platform, and wherein the protective roof is arranged above components of the lifting platform to be protected.
