Abstract

In some embodiments, an archery bow comprises a riser, a first limb and a second limb. A first rotatable member is arranged to rotate about a first axis and a second rotatable member is arranged to rotate about a second axis. A bowstring is attached to the first rotatable member and arranged to bias the first rotatable member in a first rotational direction about the first axis. A power cable is attached to the first rotatable member. A servicing string is arranged for attachment to the first rotatable member and arranged to bias the first rotatable member in a second rotational direction about the first axis.

First claim

The invention claimed is:

1. An archery bow comprising:
a riser, a first limb and a second limb;
a first rotatable member arranged to rotate about a first axis;
a second rotatable member arranged to rotate about a second axis;
a bowstring attached to the first rotatable member and the second rotatable member;
a power cable attached to the first rotatable member; and
a servicing string attachable to the archery bow;
the archery bow comprising a brace condition wherein the bowstring biases the first rotatable member in a first rotational direction about the first axis and the power cable biases the first rotatable member in a second rotational direction about the first axis;
the archery bow comprising a first cable servicing condition wherein the servicing string is attached to the first rotatable member and arranged to bias the first rotatable member in the second rotational direction about the first axis.

2. The archery bow of claim 1 , wherein a length of the servicing string is less than a length of the power cable.

3. The archery bow of claim 1 , the servicing string attached to the riser.

4. The archery bow of claim 3 , the riser comprising a post, the servicing string attached to the post.

5. The archery bow of claim 1 , the servicing string attached to the second rotatable member.

6. The archery bow of claim 5 , the servicing string crossing an axis plane that contains the first axis and the second axis.

7. The archery bow of claim 1 , the first rotatable member comprising a first cable servicing post, the servicing string attached to the first cable servicing post.

8. The archery bow of claim 7 , the second rotatable member comprising a first bowstring servicing post.

9. The archery bow of claim 7 , the second rotatable member comprising a second cable servicing post.

10. An archery bow comprising:
a riser, a first limb and a second limb;
a first rotatable member and a second rotatable member;
a bowstring extending between the first rotatable member and the second rotatable member; and
a power cable;
the archery bow comprising a brace condition wherein the power cable is under tension;
the archery bow comprising a servicing condition comprising a servicing string attached to the first rotatable member and to the second rotatable member, the servicing string biasing the first rotatable member in a first rotational direction, the servicing string biasing the second rotatably member in the first rotational direction, wherein the power cable is not under tension.

11. The archery bow of claim 10 , wherein the second rotatable member comprises an anchor post, the servicing string attached to the anchor post.

12. The archery bow of claim 10 , wherein a length of the servicing string is less than a length of the power cable.

13. The archery bow of claim 12 , the servicing string crossing an axis plane, the first rotatable member arranged to rotate about a first axis, the second rotatable member arranged to rotate about a second axis, the axis plane containing the first axis and the second axis.

14. The archery bow of claim 10 , the first rotatable member comprising a first cable servicing post, the servicing string attached to the first cable servicing post.

15. The archery bow of claim 14 , the second rotatable member comprising a first bowstring servicing post.

16. The archery bow of claim 14 , the second rotatable member comprising a second cable servicing post.

17. The archery bow of claim 10 , comprising a second power cable, the second power cable under tension in the brace condition, the archery bow comprising a second servicing condition wherein the servicing string is attached to the second rotatable member and to a secondary anchor, wherein the second power cable is not under tension.

18. An archery bow comprising:
a riser, a first limb and a second limb;
a first rotatable member arranged to rotate about a first axis, the first rotatable member comprising a first cable servicing post;
a second rotatable member arranged to rotate about a second axis, the second rotatable member comprising a bowstring servicing post;
a bowstring attached to the first rotatable member and the second rotatable member;
a first power cable engaged with the first rotatable member; and
a servicing string attachable to the archery bow;
the archery bow comprising a brace condition wherein the bowstring biases the first rotatable member in a first rotational direction about the first axis and the first power cable biases the first rotatable member in a second rotational direction about the first axis;
the archery bow comprising a first cable servicing condition wherein the servicing string is attached to the bowstring servicing post and the first cable servicing post, wherein the servicing string biases the first rotatable member in the second rotational direction about the first axis.

19. The archery bow of claim 18 , wherein the first power cable is not under tension in the first servicing condition.

20. The archery bow of claim 18 , the bowstring servicing post comprising a first bowstring servicing post, the first rotatable member comprising a second bowstring servicing post.

21. The archery bow of claim 20 , the archery bow comprising a bowstring servicing condition wherein the servicing string is attached to the first bowstring servicing post and the second bowstring servicing post.

22. The archery bow of claim 21 , wherein the bowstring is not under tension in the bowstring servicing condition.

23. The archery bow of claim 20 , the archery bow comprising a second power cable engaged with the second rotatable member, the second rotatable member comprising a second cable servicing post, in the brace condition the bowstring biases the second rotatable member in the second rotational direction about the second axis and the second power cable biases the second rotatable member in the first rotational direction about the second axis, the archery bow comprising a second cable servicing condition wherein the servicing string is attached to the second bowstring servicing post and the second cable servicing post, wherein the servicing string biases the second rotatable member in the first rotational direction about the second axis.
