Abstract

Claims (31)

1. A ball bat, comprising:

a first handle section having a first outer diameter;

a second handle section having a second outer diameter that is substantiallyequal to the first outer diameter, with the second handle section rotatably connected to the first handle section such that the first and second handle sections are freely rotatable relative to each other to allow relative rotation between the first handle section and the second handle section during a swinging motion;

a barrel; and

a tapered section joining the barrel to the second handle section, wherein a radially outer surface of the tapered section is flush and continuous with a radially outer surface of the second handle section and with a radially outer surface of the barrel.

2. The ball bat of claim 1 wherein the first handle section is connected to the second handle section via a threaded connector.

3. The ball bat of claim 1 wherein one of the first and second handle sections includes a knob, the ball bat further comprising a first bearing member positioned in the knob, and a second bearing member positioned between the first and second handle sections.

4. The ball bat of claim 1 wherein the second handle section includes a reduced-diameter region having a third outer diameter that is less than the second outer diameter, wherein the reduced-diameter region is positioned inside the first handle section.

5. The ball bat of claim 4 further comprising a release ply positioned between a radially inner surface of the first handle section and a radially outer surface of the reduced-diameter region, wherein the release ply facilitates rotation between the first and second handle sections.

6. The ball bat of claim 1 further comprising a grip positioned on at least one of the first and second handle sections.

7. The ball bat of claim 6 wherein a first grip is positioned on the first handle section and a second grip is positioned on the second handle section.

8. The ball bat of claim 1 wherein the first handle section is rotatably engaged with the second handle section via at least one bearing.

9. The ball bat of claim 1 wherein at least a portion of the first handle section is separated from at least a portion of the second handle section by at least one release ply.

10. The ball bat of claim 1 wherein the first handle section is rotatably engaged with the second handle section via at least one bearing, and at least a portion of the first handle section is separated from at least a portion of the second handle section by at least one release ply.

11. The ball bat of claim 1 wherein a portion of the first handle section is positioned inside of the second handle section, and wherein the portion of the first handle section includes at least one radially outward projection that engages an interior region of the second handle section to substantially inhibit longitudinal movement of the first handle section relative to the second handle section.

12. The ball bat of claim 1 wherein a portion of the first handle section is positioned inside of the second handle section, and wherein the second handle section includes at least one radially inward projection that engages an exterior region of the first handle section to substantially inhibit longitudinal movement of the first handle section relative to the second handle section.

13. The ball bat of claim 1 wherein the first handle section is connected to the second handle section via a threaded connector, and further comprising a bushing positioned between the first handle section and the threaded connector to facilitate relative rotation between the first and second handle sections.

14. The ball bat of claim 13 wherein the threaded connector includes at least one first opening, and the second handle section includes at least one second opening aligned with the at least one first opening, wherein a pin is positioned in the first and second openings to further secure the second handle section to the threaded connector.

15. A ball bat, comprising:

a first handle section extending in a longitudinal direction from a first end to a second end;

a second handle section extending in the longitudinal direction from a third end to a fourth end, with the third end of the second handle section in rotatable engagement with the second end of the first handle section such that the first and second handle sections are freely rotatable relative to each other to allow relative rotation between the first handle section and the second handle section during a swinging motion; and

a barrel attached to or integral with one of the first and second handle sections;

wherein the first handle section includes a threaded connector, and the second handle section includes a receiving element having internal threads that engage the threaded connector.

16. The ball bat of claim 15 further comprising at least one bearing positioned between the first and second handles sections to provide rotation between them.

17. A ball bat, comprising:

a first handle section having a first outer diameter;

a second handle section having a second outer diameter that is substantially equal to the first outer diameter, with the second handle section rotatably connected to the first handle section such that the first and second handle sections are freely rotatable relative to each other to allow relative rotation between the first handle section and the second handle section during a swinging motion;

a knob attached to or integral with the first handle section;

a barrel attached to or integral with the second handle section;

a first bearing member positioned in the knob; and

a second bearing member positioned between the first and second handle sections.
