Abstract

The invention relates to an elevator system ( 10 ) for a building under construction, comprising a vertical shaft ( 12 ), in which a temporary machine compartment ( 14 ) is retained, a driving device ( 18 ), which is arranged in the temporary machine compartment ( 14 ) and which is coupled by means of a supporting cable ( 21 ) to a car ( 23 ) that can be moved vertically up and down in the shaft ( 12 ), and a speed limiter ( 30 ), which interacts with a speed limiter cable ( 34 ) arranged in the shaft ( 12 ). According to the invention, in order to develop the elevator system in such a way that the speed limiter cable ( 34 ) can be extended in a simple manner when the temporary machine compartment ( 14 ) is moved without said action leading to permanently increased energy consumption of the elevator system ( 10 ), the speed limiter ( 30 ) is arranged on the car ( 23 ) or on a counterweight ( 25 ) connected to the car ( 23 ) by means of the supporting cable ( 21 ), and that the speed limiter cable ( 34 ) has a first and second cable section ( 32, 52 ), wherein the first cable section ( 32 ) is clamped in a stationary manner between a cable retainer ( 46 ) connected to the temporary machine compartment ( 14 ) in a stationary manner and a releasable clamping device ( 50 ) arranged in a lower shaft region ( 48 ) and the second cable section ( 52 ) is connected to the first cable section ( 32 ) in the lower shaft region ( 48 ) and is stored in a storage region.

First claim

What is claimed is:

1. An elevator system for a building under construction, the elevator system comprising:
a temporary machine compartment disposed in a vertical shaft of the building under construction;
a drive device that is disposed in the temporary machine compartment and is coupled via a supporting cable to a car that can be made to move upward and downward in the vertical shaft; and
a speed limiter for limiting a speed of the car, wherein the speed limiter cooperates with a speed limiter cable disposed in the vertical shaft, wherein the speed limiter is disposed on the car or on a counterweight connected to the car via the supporting cable, wherein the speed limiter cable has a first cable section and a second cable section, wherein the first cable section is clamped in a positionally-fixed manner between a cable retainer that is connected in a positionally-fixed manner to the temporary machine compartment and a releasable clamping device disposed in a lower shaft region, wherein the second cable section is connected to the first cable section at the releasable clamping device in the lower shaft region and is stored in a storage region.

2. The elevator system as claimed in claim 1 , wherein the storage region is disposed in the vertical shaft.

3. The elevator system as claimed in claim 1 wherein an end region of the second cable section is wound onto a cable drum in the storage region.

4. The elevator system as claimed in claim 3 wherein the vertical shaft has a pit and the cable drum is rotatably mounted in the pit.

5. The elevator system as claimed in one of the preceding claims wherein the releasable clamping device has a releasable cable clamp.

6. The elevator system as claimed in claim 5 , wherein the releasable cable clamp cooperates with a clamping weight that can be made to move in the vertical direction.

7. The elevator system as claimed in claim 6 wherein the clamping weight has a carriage that is held on a guiding device such that the carriage can be displaced in the vertical direction, on which at least one weight element is held, and which is connected to the releasable cable clamp.

8. The elevator system as claimed in claim 7 wherein the guiding device has two guiding rails.

9. The elevator system as claimed in one of claims 1 - 4 wherein the car is guided on guiding rails.

10. The elevator system as in one of claims 1 - 4 wherein the storage region is disposed in the lower shaft region.

11. The elevator system as in one of claim 1 , 3 , or 4 wherein the storage region is disposed outside the vertical shaft.

12. An elevator system for a building under construction, the elevator system comprising:
a temporary machine compartment disposed in a shaft of the building under construction;
a drive device that is disposed in the temporary machine compartment and is coupled via a supporting cable to a car that moves within the shaft; and
a speed limiter for limiting a speed of the car, wherein the speed limiter cooperates with a speed limiter cable that is disposed in the shaft and has a first cable section and a second cable section, the first cable section being clamped between a cable retainer that is connected to the temporary machine compartment and a releasable clamping device, the second cable section being connected to the first cable section at the releasable clamping device, which is disposed in a lower shaft region beneath the car.

13. The elevator system of claim 12 wherein an end region of the second cable section is wound onto a cable drum disposed in a storage region disposed outside the shaft.

14. The elevator system of claim 12 wherein the shaft includes a pit, wherein an end region of the second cable section is wound onto a cable drum disposed in the pit.

15. The elevator system of claim 12 wherein the releasable clamping device comprises a releasable cable clamp that cooperates with a clamping weight configured to move vertically.

16. The elevator system of claim 15 wherein at least the first cable section of the speed limiter cable is put in tension by the clamping weight.

17. The elevator system of claim 16 wherein the clamping weight comprises a carriage that is held on a guiding device that permits the carriage to move vertically.

18. The elevator system of one of claims 12 - 17 wherein the speed limiter is disposed on the car or on a counterweight connected to the car.

19. The elevator system of one of claims 12 - 17 wherein the first cable section is clamped in a positionally-fixed manner between the cable retainer and the releasable clamping device.
