Abstract

An elevator system includes a hoistway, an elevator car movable along the hoistway, and one or more belts operably connected to the elevator car to propel the elevator car along the hoistway. A belt of the one or more belts includes one or more tension elements extending along a belt length, and a jacket at least partially encapsulating the one or more tension elements. The jacket includes a jacket base formed from a first material and one or more insert layers embedded in the jacket base material. The one or more insert layers have a corrugated shape along the belt length, and are formed from a second material different from the first material.

First claim

What is claimed is:

1. A belt for an elevator system, comprising:
one or more tension elements extending along a belt length; and
a jacket at least partially encapsulating the one or more tension elements, the jacket including:
a jacket base; and
one or more insert layers embedded in the jacket base, the one or more insert layers having a corrugated shape along the belt length.

2. The belt of claim 1 , wherein the corrugated shape is one or more of sinusoidal, triangular or rectangular.

3. The belt of claim 1 , wherein the jacket base is formed from a first material and the insert layer is formed from a second material different from the first material.

4. The belt of claim 3 , wherein the second material is non-elastomeric and has a melting temperature that is at least 10° C. higher than the processing temperature required to form the jacket base material.

5. The belt of claim 1 , wherein the one or more insert layers contact the one or more tension elements.

6. The belt of claim 1 , wherein the corrugated shape has a peak to valley height of at least three times a thickness of the insert layer.

7. The belt of claim 6 , wherein the corrugated shape has a peak to valley height of at least four times a thickness of the insert layer.

8. The belt of claim 1 , wherein a tension element of the one or more tension elements is formed from a plurality of steel wires.

9. The belt of claim 1 , further comprising an adhesive layer to secure the one or more insert layers to the base material.

10. An elevator system, comprising:
a hoistway;
an elevator car movable along the hoistway;
one or more belts operably connected to the elevator car to urge the elevator car along the hoistway, a belt of the one or more belts including:
one or more tension elements extending along a belt length; and
a jacket at least partially encapsulating the one or more tension elements, the jacket including:
a jacket base formed from a first material; and
one or more insert layers embedded in the jacket base material, the one or more insert layers having a corrugated shape along the belt length, the one or more insert layers formed from a second material different from the first material.

11. The elevator system of claim 10 , wherein the corrugated shape is one or more of sinusoidal, triangular or rectangular.

12. The elevator system of claim 10 , wherein the second material is non-elastomeric and has a melting temperature that is at least 10° C. higher than the processing temperature required to form the jacket base material.

13. The elevator system of claim 10 , wherein the one or more insert layers contact the one or more tension elements.

14. The elevator system of claim 10 , wherein the corrugated shape has a peak to valley height of at least three times a thickness of the insert layer.

15. The elevator system of claim 14 , wherein the corrugated shape has a peak to valley height of at least four times a thickness of the insert layer.

16. The elevator system of claim 10 , wherein a tension element of the one or more tension elements is formed from a plurality of steel wires.
