Sporting-good implement with rotatable handle
View Patent ↗A sporting-good implement, such as a ball bat or a lacrosse stick, includes a first handle section rotatably connected to a second handle section. The second handle section may be attached to or integral with a tapered region or barrel region of a ball bat, or with a shaft section or head of a lacrosse stick, or with another sporting-good feature. This rotatable engagement allows the relative position of the user's hands to change during the course of a swing, shot, or pass, ideally placing the user's hands in a position to generate improved power or control.
1. A ball bat, comprising:
a first handle section comprising a knob positioned on a free end of the ball bat, the first handle section having a first outer diameter;
a second handle section having a first region including a second outer diameter that is substantially equal to the first outer diameter, and a second region having a third outer diameter that is less than the first and second outer diameters, wherein the first handle section is positioned over the second region of the second handle section;
a barrel; and
a tapered section joining the barrel to the second handle section; wherein
the barrel and the second handle section rotate freely relative to the first handle section.
2. The ball bat of claim 1 wherein the first handle section is rotatably engaged with the second region of the second handle section via at least one bushing, bearing, or release ply.
3. The ball bat of claim 1 wherein a low-friction element is positioned over the second region of the second handle section between the first handle section and the second handle section.
4. The ball bat of claim 3 wherein the low-friction element comprises a sleeve made of a low-friction material.
5. The ball bat of claim 3 further comprising a flexible grip positioned over the first handle section and over the low-friction element.
6. A ball bat, comprising:
a first handle section comprising a knob positioned on a free end of the ball bat, the first handle section having a first outer diameter;
a second handle section including a first portion having a second outer diameter that is less than the first outer diameter, and a second portion having a third outer diameter that is substantially equal to the first outer diameter, wherein the first handle section is positioned over, and freely rotatably engaged with, the first portion of the second handle section, and wherein a radially outer surface of the first handle section is flush with a radially outer surface of the second portion of the second handle section; and
a bat barrel attached to or integral with the second handle section.
7. The ball bat of claim 6 wherein the first handle section is rotatably engaged with the second handle section via at least one bushing, bearing, or release ply.
8. The ball bat of claim 6 wherein a low-friction element is positioned over the first portion of the second handle section between the first handle section and the second handle section.
9. The ball bat of claim 6 further comprising a flexible grip positioned over the first handle section and over the second handle section.
10. The ball bat of claim 6 further comprising a first grip element positioned over the first handle section and a second grip element separate from the first grip element and positioned over the second handle section.
11. A ball bat, comprising:
a barrel;
a first handle section comprising a knob positioned on a free end of the ball bat opposite the barrel;
a second handle section joined to the barrel, the second handle section having a first region including a first outer diameter and a second region including a second outer diameter that is smaller than the first outer diameter; wherein
the first handle section is positioned over the second region of the second handle section; and wherein
the first handle section is rotatably engaged with the second handle section via a bushing, a bearing, or a release ply.
12. The ball bat of claim 11 wherein a radially outer surface of the first handle section is flush with a radially outer surface of the first region of the second handle section.
13. The ball bat of claim 11 wherein the first handle section is rotatably engaged with the second handle section via a bushing or a bearing positioned within the knob.
14. The ball bat of claim 11 comprising a release ply positioned over the second region of the second handle section between the second region of the second handle section and the first handle section.
15. The ball bat of claim 11 further comprising a flexible grip positioned over the first handle section and the first region of the second handle section.
16. The ball bat of claim 11 further comprising a first grip element positioned over the first handle section and a second grip element separate from the first grip element and positioned over the second handle section.
