Abstract

In an embodiment of the invention, a universal shaft fitting for a cue stick comprises a universal adapter with an extension having external threads, adapted to be bonded into the butt end of a shaft of a cue stick, and an insert adapted to be bonded to internal threads of the universal adapter. The insert also includes internal threads for detachably mating a pin attached to another segment of a cue stick. Other embodiments include universal shaft fittings with various pin configurations and universal shaft fittings that do not utilize an insert. The universal shaft fittings may be utilized as components of a kit for adapting shafts to receive segments of cue sticks with various pin configurations. The universal shaft fittings may also be utilized in a method of supplying shafts to fit segments of cue sticks.

Claims

1. A universal fitting kit for adapting a set of first segments of cue sticks to receive a set of second segments of cue sticks, the set of second segments having various threaded configurations, the kit comprising:

a set of universal fittings having varying complementary threaded configurations to detachably receive the various threaded configurations of the second segments, each universal fitting having a common complementary end configuration adapted to be bonded to a common end configuration of any member of the set of first segments;

the set of first segments is a set of shafts;

the set of second segments have various pin configurations; and

the set of universal fittings includes a set of universal shaft fittings having internally threaded sections of various thread configurations to detachably receive the various pin configurations of the second segments, each universal shaft fitting having a common shaft end externally threaded configuration adapted to be bonded to a butt end of any member of the set of shafts.

2. A kit according to claim 1, wherein a member of the set of universal shaft fittings comprises:

a universal adapter having the common shaft end externally threaded configuration adapted to be bonded to the butt end of any member of the set of shafts; and

an insert adapted to be bonded to the universal adapter, the insert having an internally threaded region to receive a particular pin configuration of at least one member of the set of second segments.

3. A kit according to claim 2, wherein the universal adapter includes polyethylene terephthalate.

4. A kit according to claim 2, wherein the insert includes brass.

5. A kit according to claim 1 further comprising:

a set of receivers, each receiver adapted to be bonded to the butt end of any member of the set of shafts, each receiver having a common internally threaded configuration to mate and bond with the common shaft end externally threaded configuration of a universal shaft fitting.

6. A kit according to claim 1, wherein a member of the set of universal shaft fittings includes a substantially circular cross section surface with a diameter between about 0.82 inches and about 0.86 inches.

7. A kit according to claim 6, wherein the diameter is one of about 0.835 inches, about 0.841 inches, about 0.845 inches, and about 0.850inches.

8. A kit according to claim 1, wherein an internally threaded section of a member of the set of universal shaft fittings is configured with ball screw threads.

9. A kit according to claim 1, wherein an internally threaded section of a member of the set of universal shaft fittings is configured with one of ⅜

-10 threads, 5/16-14 threads, and 5/16-18 threads.

10. A kit according to claim 1, wherein an internally threaded section of a member of the set of universal shaft fittings is configured to firmly and detachably mate a pin of a member of the set of second segments within about one revolution.

11. A kit with component parts capable of being assembled to create a set of adapted first segments of cue sticks to receive a set of second segments of cue sticks, the set of second segments having various threaded configurations, the kit comprising:

a set of first segments having a common end configuration; and

a set of universal fittings having various complementary threaded configurations to detachably mate the various threaded configurations of the second segments, each universal fitting having a common complementary end configuration adapted to be bonded to the common end configuration of any member of the set of first segments.

12. A kit according to claim 11, wherein

the set of second segments have various pin configurations;

the set of first segments includes a set of shafts having a common butt end; and

the set of universal fittings includes a set of universal shaft fittings having internally threaded sections of various thread configurations to detachably receive the various pin configurations of the segments, each universal shaft fitting having a common shaft end externally threaded configuration adapted to be bonded to the common butt end of any member of the set of shafts.

13. A kit according to claim 12, wherein each universal shaft fitting comprises:

a universal adapter having the common shaft end externally threaded configuration adapted to be bonded to the common butt end of any member of the set of shafts; and

an insert adapted to be bonded to the universal adapter, the insert having an internally threaded region to receive a particular pin configuration of at least one member of the set of second segments.

14. A kit according to claim 12 further comprising:

a set of receivers, each receiver adapted to be bonded to the common butt end of any member of the set of shafts, each receiver having a common internally threaded configuration to mate and bond with the common shaft end externally threaded configuration of a universal shaft fitting.
