Abstract

A tool is provided for holding a cable fixing bolt of a bicycle component in a loose condition. This tool allows the cable fixing bolt to be shipped and stored in loose condition, while preventing the cable fixing bolt from falling out of a bicycle component. The tool can be used with the cable fixing bolt derailleurs or brake device. The tool basically has three portions. The first portion engages a head portion of the cable fixing bolt. The second portion is spaced from the first portion and is located adjacent a threaded shaft portion of the cable fixing bolt. The third portion is spaced from the second portion and engages a part of the bicycle component (e.g., a nut, a link or a brake arm). In each embodiment, the first, second and third portions are arranged relative one another to hold the cable fixing bolt in a loose condition, while preventing the cable fixing bolt from being disengaged from the part of the bicycle component. In selected embodiments where the tool is used with a rear derailleur, the third portion holds the rear derailleur in a retracted position.

Claims

1. A bicycle component assembly, comprising:

a bicycle component having a first bicycle part with a threaded bolt receiving opening;

a cable fixing bolt having a head portion and a shaft portion that extends from said head portion to a free end, said shaft portion having threads formed thereon that are engaged with said threaded bolt receiving opening; and

a tool removably coupled to said cable fixing bolt, said tool including;

first portion engaging said head portion of said cable fixing bolt,

a second portion located adjacent a portion of said shaft portion of said cable fixing bolt, and

a third portion engaging at least one of said shaft portion and said first bicycle part,

said first, second and third portions being arranged relative one another to hold said cable fixing bolt in a loose condition, while preventing said cable fixing bolt from being disengaged from said first bicycle part.

2. A bicycle component assembly according to claim 1, wherein

said bicycle component is a rear derailleur.

3. A bicycle component assembly according to claim 1, wherein

said bicycle component is a front derailleur.

4. A bicycle component assembly according to claim 1, wherein

said bicycle component is a brake device.

5. A bicycle component assembly according to claim 1, further comprising

a cable fixing plate located on said shaft portion between said head portion and said first bicycle part.

6. A bicycle component assembly according to claim 1, wherein

said tool is formed of a non-metallic material.

7. A bicycle component assembly according to claim 1, wherein

said second portion of said tool has a recess with said shaft portion of said cable fixing bolt located therein.

8. A bicycle component assembly according to claim 1, wherein

said first, second and third portions of said tool are substantially parallel members.

9. A bicycle component assembly according to claim 1, wherein

said first, second and third portions of said tool are integrally formed as a one-piece, unitary member.

10. A bicycle component assembly according to claim 1, wherein

said first and second portions of said tool are substantially parallel members, while said third portion of said tool is retained between said first bicycle part and a second bicycle part by a biasing member.

11. A bicycle component assembly according to claim 1, wherein

said third portion engages said shaft portion of said cable fixing bolt.

12. A bicycle component assembly according to claim 1, wherein

said third portion engages said first bicycle part.

13. A bicycle component assembly according to claim 2, wherein

said first bicycle part is a link member of said rear derailleur.

14. A bicycle component assembly according to claim 2, wherein

said first bicycle part is a nut positioned adjacent a link member of said rear derailleur that has non-threaded hole with said shaft portion being located therein.

15. A bicycle component assembly according to claim 3, wherein

said first bicycle part is a link member of said front derailleur.

16. A bicycle component assembly according to claim 3, wherein

said first bicycle part is a nut positioned adjacent a link member of said front derailleur that has non-threaded hole with said shaft portion being located therein.

17. A bicycle component assembly according to claim 4, wherein

said first bicycle part is a brake arm.

18. A bicycle component assembly according to claim 10, wherein

said biasing member urges said first and second bicycle parts from a retracted position to an extended position, said third portion of said tool being located between said first and second bicycle parts to prevent said first and second bicycle parts from moving to said extended position.

19. A bicycle component assembly according to claim 11, further comprising

a cable fixing plate located on said shaft portion between said head portion and said first bicycle part.

20. A bicycle component assembly according to claim 11, wherein

said third portion includes a bore that receives said free end of said shaft portion therein.

21. A bicycle component assembly according to claim 12, wherein

said first, second and third portions of said tool are substantially parallel members.

22. A bicycle component assembly according to claim 18, further composing

a cable fixing plate located on said shaft portion between said head portion and said first bicycle part.

23. A bicycle component assembly according to claim 12, wherein

said third portion of said tool is retained between said first bicycle part and a second bicycle part by a biasing member that urges said first and second bicycle parts from a retracted position to an extended position, said third portion of said tool being located between said first and second bicycle parts to prevent said first and second bicycle parts from moving to said extended position.

24. A bicycle component assembly according to claim 20, wherein

said bore of said third portion is a blind bore that receives said free end of said shaft portion therein.

25. A bicycle component assembly according to claim 20, wherein

said bore of said third portion is a through bore that receives said free end of said shaft portion therein.

26. A bicycle component assembly according to claim 21, further composing

a cable fixing plate located on said shaft portion between said head portion and said first bicycle part.

27. A bicycle component assembly according to claim 23, wherein

said third portion of said tool has a recess that engages said second bicycle part to limit relative movement therebetween.

28. A bicycle component assembly according to claim 27, wherein

said first and second portions of said tool are substantially parallel members.

29. A bicycle component assembly according to claim 28, further comprising

a cable fixing plate located on said shaft portion between said head portion and said first bicycle part.
