Abstract

A spool system includes a spool and a spool support. The spool includes a spool body, a shaft, and an anti-rotation feature. The spool body has a center axis of rotation. The shaft includes a first end disposed on the spool body and extends from the spool body along the center axis of rotation to a second end. The anti-rotation feature is disposed on the shaft and defines a non-circular shape. The spool support supports the spool and defines a slot sized to slidably receive the shaft and a feature receiver that has a complimentary shape of the anti-rotation feature. The spool moves along the slot between a stowed position and a deployed position. In the stowed position, the anti-rotation feature of the spool is received by the feature receiver and prevents rotation of the spool. In the deployed position, the anti-rotation feature allows rotation of the spool.

First claim

What is claimed is:

1. A spool system comprising:
a spool comprising:
a spool body having a center axis of rotation;
a shaft having a first end disposed on the spool body and extending from the spool body along the center axis of rotation to a second end; and
an anti-rotation feature disposed on the shaft, the anti-rotation feature defining a non-circular shape; and

a spool support supporting the spool, the spool support defining:
a slot sized to slidably receive the shaft, the slot having a first side and a second side opposite the first side; and
a feature receiver having a complementary shape of the anti-rotation feature,
wherein the slot includes:
a first feature guide disposed on the first side of the slot and configured to guide the anti-rotation feature towards the feature receiver; and
a second feature guide disposed on the second side of the slot and configured to guide the anti-rotation feature towards the feature receiver, the first feature guide offset from the second feature guide by a distance extending parallel to the slot, and

wherein the spool moves along the slot in a direction extending perpendicular to the center axis of rotation between a stowed position and a deployed position, the anti-rotation feature of the spool received by the feature receiver while in the stowed position, preventing rotation of the spool, the anti-rotation feature of the spool unseated from the feature receiver while in the deployed position, allowing rotation of the spool.

2. The spool system of claim 1 , wherein the anti-rotation feature is disposed on the second end of the shaft.

3. The spool system of claim 1 , wherein the anti-rotation feature defines a square shape.

4. The spool system of claim 1 , wherein the slot has first and second ends, one end of the slot defining the feature receiver.

5. The spool system of claim 1 , wherein the spool support comprises:
a base; and
a cantilevered arm disposed on the base, the cantilevered arm defining the slot and the feature receiver.

6. The spool system of claim 5 , wherein the base defines a spool seat, the spool seated in the spool seat while in the stowed position.

7. The spool system of claim 5 , wherein the spool support further comprises a spool splitter disposed on the base.

8. The spool system of claim 1 , wherein the spool body comprises:
a flanged cylinder defining a bore; and
a shaft support disposed in the bore and receiving the shaft;
wherein rotation of the shaft causes rotation of the flanged cylinder.

9. The spool system of claim 1 , wherein the spool body comprises:
first and second ringed discs spaced parallel from each other; and
a spool core disposed between the ringed discs and receiving the shaft;
wherein rotation of the shaft causes rotation of the spool core.

10. The spool system of claim 9 , wherein one of the ringed discs defines a slit extending from an inner diameter of the ringed disc to an outer diameter of the ringed disc.

11. The spool system of claim 1 , wherein the anti-rotation feature extends radially outward from the shaft.

12. A method comprising:
moving a spool from a stowed position to a deployed position on a spool support supporting the spool, the spool comprising:
a spool body having a center axis of rotation;
a shaft having a first end disposed on the spool body and extending from the spool body along the center axis of rotation to a second end;
an anti-rotation feature disposed on the shaft, the anti-rotation feature defining a non-circular shape; and
a spool support supporting the spool, the spool support defining:
a slot sized to slidably receive the shaft, the slot having a first side and a second side opposite the first side; and
a feature receiver having a complementary shape of the anti-rotation feature,
wherein the slot includes:
a first feature guide disposed on the first side of the slot and configured to guide the anti-rotation feature towards the feature receiver; and
a second feature guide disposed on the second side of the slot and configured to guide the anti-rotation feature towards the feature receiver, the first feature guide offset from the second feature guide by a distance extending parallel to the slot, and

wherein the spool moves between the stowed position and the deployed position along a slot defined by a spool support, the anti-rotation feature of the spool unseated from a feature receiver defined by the spool support while in the deployed position, allowing rotation of the spool;

paying out a length of cable spooled on the spool; and
moving the spool in a direction extending perpendicular to the center axis of rotation from the deployed position to the stowed position, the anti-rotation feature of the spool received by the feature receiver while in the stowed position, the feature receiver having a complementary shape of the anti-rotation feature preventing rotation of the spool.

13. The method of claim 12 , further comprising moving the spool onto a spool seat defined by the spool support when the spool is the stowed position.

14. The method of claim 12 , further comprising connecting a connector disposed on one end of the cable to a spool splitter disposed on the spool support.

15. The method of claim 12 , wherein the spool support comprises:
a base; and
a cantilevered arm disposed on the base, the cantilevered arm defining the slot and the feature receiver.

16. The method of claim 12 , wherein the anti-rotation feature is disposed on the second end of the shaft.

17. The method of claim 12 , wherein the anti-rotation feature defines a square shape.

18. The method of claim 12 , wherein the slot has first and second ends, one end of the slot defining the feature receiver.

19. The method of claim 12 , wherein the spool body comprises:
a flanged cylinder defining a bore; and
a shaft support disposed in the bore and receiving the shaft;
wherein rotation of the shaft causes rotation of the flanged cylinder.

20. The method of claim 12 , wherein the spool body comprises:
first and second ringed discs spaced parallel from each other; and
a spool core disposed between the ringed discs and receiving the shaft;
wherein rotation of the shaft causes rotation of the spool core.

21. The method of claim 20 , wherein one of the ringed discs defines a slit extending from an inner diameter of the ringed disc to an outer diameter of the ringed disc.
