Abstract

In some embodiments, an archery bow axle comprises a first portion and a second portion. The second portion is configured for fixed attachment to said first portion in one of a plurality of positions. The axle will have a different length in each of the positions. In some embodiments, an axle comprises a shaft and an end cap having a cavity, wherein a portion of the shaft is received in the cavity.

First claim

The invention claimed is:

1. An archery bow axle comprising:
a shaft having a first end portion and a second end portion, the first end portion shaped differently from the second end portion;
an end cap defining a cavity; and
a retainer configured for attachment to said second end portion, the retainer shaped differently from the end cap;
wherein the shaft is attached to the end cap, the first end portion is oriented in the cavity and the first end portion and cavity are sized to have an interference fit, and wherein an amount of overlap between the shaft and the end cap can be adjusted to adjust a length of the axle.

2. The archery bow axle of claim 1 , wherein said cavity is cylindrical.

3. The archery bow axle of claim 1 , said cap comprising a raised ridge.

4. The archery bow axle of claim 1 , said second end portion comprising a rounded end portion.

5. The archery bow axle of claim 1 , said first end portion comprising barb serrations.

6. The archery bow axle of claim 5 , wherein a barb serration comprises a frustoconical portion.

7. The archery bow axle of claim 5 , wherein a barb serration comprises a cylindrical portion.

8. The archery bow axle of claim 7 , wherein said cylindrical portion comprises a diameter similar to a diameter of a midportion of said shaft.

9. The archery bow axle of claim 1 , said second end portion comprising a groove.

10. The archery bow axle of claim 1 , said retainer comprising a wall portion and a flange portion oriented orthogonal to the wall portion.

11. The archery bow axle of claim 1 , said retainer comprising an aperture arranged to engage said shaft.

12. The archery bow axle of claim 11 , said aperture comprising a first portion and a second portion, the second portion being larger than the first portion.

13. The archery bow axle of claim 11 , wherein said aperture comprises a figure-eight shape.

14. The archery bow axle of claim 1 , wherein a cross-sectional shape of said shaft is similar to a cross-sectional shape of said cavity.

15. An archery bow axle comprising:
a shaft having a first end and a second end;
an end cap configured for an interference fit attachment to the first end in one of a plurality of positions, the axle having a different length in each position; and
a retainer configured for attachment to the second end, the retainer shaped differently from the end cap.

16. The archery bow axle of claim 15 , the first end comprising barb serrations.

17. The archery bow axle of claim 16 , the second end comprising a groove.

18. The archery bow axle of claim 15 , the retainer comprising a wall portion having an aperture arranged to receive the second end, the retainer comprising a flange oriented at an angle to the wall portion.

19. The archery bow axle of claim 15 , the second end of the shaft comprising a groove.
