Abstract

An elevator system includes an elevator car movable along a hoistway, a traveling cable operably connected to the elevator car and movable along the hoistway with the elevator car, and a traveling cable support positioned in the hoistway and operably connected to the traveling cable to prevent sway of the traveling cable. A traveling cable and traveling cable support arrangement for an elevator system includes a traveling cable positioned in a hoistway and movable in the hoistway during elevator system operation, and a traveling cable support positioned in the hoistway and operably connected to the traveling cable to prevent sway of the traveling cable, the traveling cable support operably connected to the traveling cable via a plurality of guide frames.

First claim

What is claimed is:

1. An elevator system, comprising:
an elevator car movable along a hoistway;
a traveling cable operably connected to the elevator car and movable along the hoistway with the elevator car;
a traveling cable support disposed in the hoistway and operably connected to the traveling cable to prevent sway of the traveling cable; and
a plurality of guide frames extending from the traveling cable to the travelling cable supports and slidably along the traveling cable support, a guide frame of the plurality of guide frames including:
a support opening enclosing the traveling cable support; and
a cable opening enclosing the traveling cable.

2. The elevator system of claim 1 , wherein the plurality of guide frames are movable along the traveling cable and/or along the traveling cable support.

3. The elevator system of claim 1 , wherein the plurality of guide frames is three guide frames.

4. The elevator system of claim 1 , further comprising one or more stops disposed along the traveling cable support to limit movement of the plurality of guide frames along the traveling cable support.

5. The elevator system of claim 4 , wherein the one or more stops are positioned between adjacent guide frames of the plurality of guide frames.

6. The elevator system of claim 4 , wherein the one or more stops are fixed to the traveling cable support.

7. The elevator system of claim 1 , wherein:
the support opening is disposed at a first end of the guide frame; and
the cable opening is disposed at a second end of the guide frame opposite the first end.

8. The elevator system of claim 1 , wherein the guide frame includes a coating to reduce friction between the guide frame and the traveling cable support and/or the traveling cable.

9. A traveling cable and traveling cable support arrangement for an elevator system, comprising:
a traveling cable disposed in a hoistway and movable in the hoistway during elevator system operation; and
a traveling cable support disposed in the hoistway and operably connected to the traveling cable to prevent sway of the traveling cable, the traveling cable support operably connected to the traveling cable via a plurality of guide frames, the plurality of guide frames movable along the traveling cable and along the traveling cable support a guide frame of the plurality of guide frames including:
a support opening enclosing the traveling cable support; and
a cable opening enclosing the traveling cable.

10. The traveling cable and traveling cable support arrangement of claim 9 , wherein the plurality of guide frames is three guide frames.

11. The traveling cable and traveling cable support arrangement of claim 9 , further comprising one or more stops disposed along the traveling cable support to limit movement of the plurality of guide frames along the traveling cable support.

12. The traveling cable and traveling cable support arrangement of claim 11 , wherein the one or more stops are positioned between adjacent guide frames of the plurality of guide frames.

13. The traveling cable and traveling cable support arrangement of claim 11 , wherein the one or more stops are fixed to the traveling cable support.

14. The traveling cable and traveling cable support arrangement of claim 9 , wherein:
the support opening is disposed at a first end of the guide frame; and
the cable opening is disposed at a second end of the guide frame opposite the first end.

15. The traveling cable and traveling cable support arrangement of claim 9 , wherein the guide frame includes a coating to reduce friction between the guide frame and the traveling cable support and/or the traveling cable.
