Abstract

The invention concerns a lift system with at least one lift car able to ride in a lift shaft, while a travelling cable is provided, having a first end at the lift car side and a second end at the shaft side, wherein the weight force of the travelling cable is at least partially channelled into a traction means or balancing means engaging with the lift car.

First claim

What is claimed is:

1. A lift system comprising:
at least one lift car configured to ride in a lift shaft;
a traction means coupled to a top of the lift car and configured to support said lift car in the lift shaft; and
a traveling cable having a first end disposed at a side or an underside of said lift car and coupled to said traction means above said lift car, and a second end disposed at a side of said lift shaft, a weight force of said traveling cable being at least partially supported by said traction means above said lift car, wherein at least a portion of the weight force of the traveling cable that is supported by the traction means is channeled around the at least one lift car.

2. The lift system of claim 1 , wherein said traction means is a traction cable of said lift car.

3. The lift system of claim 1 , further comprising:
a support structure affixed to said traction means above said lift car, and further coupled to said traveling cable, said support structure configured to support the weight force of said traveling cable.

4. The lift system of claim 3 , further comprising a balancing weight disposed on said support structure and configured to at least partially balance out a torque applied to said traction means by said weight force of said traveling cable acting on said support structure affixed to said traction means.

5. The lift system of claim 3 , wherein said support structure is coupled at a first location thereof to said traction means, and is coupled at a second location thereof to said traveling cable.

6. The lift system of claim 3 , wherein said support structure is pivotably mounted to said lift car.

7. The lift system of claim 3 , further comprising:
a slide member coupled to a side of the lift car; and
a suspension member coupled to and vertically slidable in said slide member, and coupled to said first end of said traveling cable, so as to permit said first end of said traveling cable to slide vertically with respect to said lift car; and
a connecting mechanism coupled at a first end thereof to said suspension member and at a second end thereof to said support structure.

8. The lift system of claim 3 , further comprising:
a pivoting lever pivotably mounted at a fixed end to said lift car, and further mounted to said travelling cable at a location distal from said fixed end; and
a connecting element coupled between each of a free end of said pivoting lever and said support structure, and configured to transmit at least a portion of said weight force from said traveling cable to said support structure.

9. The lift system of claim 1 , further comprising:
a balance rope coupled to said lift car, and configured to serve as a balancing means for said lift car and support at least a portion of said weight force of said traveling cable.

10. The lift system of claim 9 , further comprising:
a slide member coupled to a side of the lift car; and
a suspension member coupled to and vertically slidable in said slide member, and coupled to said first end of said traveling cable, so as to permit said first end of said traveling cable to slide vertically with respect to said lift car;
a connecting element coupled between each of said suspension member and one of said balance rope or a support structure that is coupled to said balance rope.

11. The lift system of claim 9 , further comprising:
a pivoting lever pivotably mounted at a fixed end to said lift car, and further mounted to said travelling cable at a location distal from said fixed end; and
a connecting element coupled between each of a free end of said pivoting lever and said balance rope, and configured to transmit at least a portion of said weight force from said traveling cable to said balance rope.

12. The lift system of claim 1 , further comprising:
a plurality of guide rollers coupled to said lift car; and
a guide mechanism disposed in the lift shaft, and configured to permit said guide rollers of said lift car to ride there along.

13. The lift system of claim 1 , further comprising:
at least one guide mechanism disposed in the lift shaft;
a non-contact magnetic guidance mechanism disposed on said lift car that is configured to permit said lift car to ride along said guide mechanism without said lift car contacting said guide mechanism.

14. A lift system comprising:
at least one lift car configured to ride in a lift shaft;
a traction means coupled to a top of the lift car and configured to support said lift car in the lift shaft;
a balancing means coupled to said lift car; and
a traveling cable having a first end disposed at a side or an underside of said lift car and coupled to said balancing means, and a second end disposed at a side of said lift shaft, a weight force of said traveling cable being at least partially supported by said balancing means, wherein at least a portion of the weight force of the traveling cable that is supported by the balancing means is channeled around the at least one lift car.
