Abstract

A spring-pulley system is configured for use within an IT component and includes a cable assembly configured to electrically couple a fixed portion of an IT component to a slidable portion of the IT component. A pulley assembly is configured to engage the cable assembly. A spring assembly is configured to bias the pulley assembly toward a first position to absorb any slack in the cable assembly.

First claim

What is claimed is:

1. A spring-pulley system configured for use within an IT component, the spring-pulley system comprising:
a cable assembly configured to electrically couple a fixed portion of the IT component to a slidable portion of the IT component, wherein the cable assembly is configured to be drawn out of a first end of the spring-pulley system in a direction opposite of the direction of sliding of the slidable portion of the IT component while sliding the slidable portion of the IT component out from a front side of the IT component;
a pulley assembly configured to engage the cable assembly; and
a spring assembly configured to bias the pulley assembly toward a first position to absorb any slack in the cable assembly;
wherein the spring-pulley system is incorporated into a side of the slidable portion of the IT component.

2. The spring-pulley system of claim 1 wherein a first end of the cable assembly is coupled to the fixed portion of the IT component.

3. The spring-pulley system of claim 1 wherein a second end of the cable assembly is coupled to the slidable portion of the IT component.

4. The spring-pulley system of claim 1 wherein the spring assembly includes at least one constant force spring.

5. The spring-pulley system of claim 4 wherein the at least one constant force spring includes at least one coil configured to be coupled to the pulley assembly.

6. The spring-pulley system of claim 1 wherein the cable assembly is a portion of an internal cable bundle.

7. The spring-pulley system of claim 1 wherein the cable assembly is configured to provide electrical power from the fixed portion of the IT component to the slidable portion of the IT component.

8. The spring-pulley system of claim 1 wherein the spring-pulley system is coupled to the slidable portion of the IT component.

9. The spring-pulley system of claim 1 wherein the cable assembly is configured to electrically couple at least a portion of a cabling module to at least a portion of an external cable termination module.

10. The spring-pulley system of claim 9 wherein the cabling module is included within the slidable portion of the IT component.

11. The spring-pulley system of claim 9 wherein the external cable termination module is included within the fixed portion of the IT component.

12. A spring-pulley system configured for use within an IT component, the spring-pulley system comprising:
a cable assembly configured to electrically couple a fixed portion of the IT component to a slidable portion of the IT component, wherein a first end of the cable assembly is coupled to the fixed portion of the IT component and a second end of the cable assembly is coupled to the slidable portion of the IT component, wherein the cable assembly is configured to be drawn out of a first end of the spring-pulley system in a direction opposite of the direction of sliding of the slidable portion of the IT component while sliding the slidable portion of the IT component out from a front side of the IT component;
a pulley assembly configured to engage the cable assembly; and
a spring assembly configured to bias the pulley assembly toward a first position to absorb any slack in the cable assembly;
wherein the spring-pulley system is incorporated into a side of the slidable portion of the IT component.

13. The spring-pulley system of claim 12 wherein the spring assembly includes at least one constant force spring.

14. The spring-pulley system of claim 13 wherein the at least one constant force spring includes at least one coil configured to be coupled to the pulley assembly.

15. The spring-pulley system of claim 12 wherein the spring-pulley system is coupled to the slidable portion of the IT component.

16. The spring-pulley system of claim 12 wherein the cable assembly is configured to electrically couple at least a portion of a cabling module to at least a portion of an external cable termination module.

17. The spring-pulley system of claim 16 wherein the cabling module is included within the slidable portion of the IT component.

18. The spring-pulley system of claim 16 wherein the external cable termination module is included within the fixed portion of the IT component.

19. A spring-pulley system configured for use within an IT component, the spring-pulley system comprising:
a cable assembly configured to electrically couple a fixed portion of the IT component to a slidable portion of the IT component, wherein the cable assembly is a portion of an internal cable bundle and is configured to provide electrical power from the fixed portion of the IT component to the slidable portion of the IT component, wherein the cable assembly is configured to be drawn out of a first end of the spring-pulley system in a direction opposite of the direction of sliding of the slidable portion of the IT component while sliding the slidable portion of the IT component out from a front side of the IT component;
a pulley assembly configured to engage the cable assembly; and
a spring assembly configured to bias the pulley assembly toward a first position to absorb any slack in the cable assembly;
wherein the spring-pulley system is incorporated into a side of the slidable portion of the IT component.

20. The spring-pulley system of claim 19 wherein:
a first end of the cable assembly is coupled to the fixed portion of the IT component; and
a second end of the cable assembly is coupled to the slidable portion of the IT component.
