Bat having a sleeve with holes
View Patent ↗Disclosed herein is a bat comprising a handle portion, a transition portion attached to the handle portion, and a barrel portion attached to the transition portion. The barrel portion includes one or more first cross-sections having a first stiffness and a plurality of second cross-sections having a second stiffness. Each first cross-section is beside one second cross-section or between two of the second cross-sections and the first stiffness is greater than the second stiffness. The variance in stiffness between the first cross-sections and the second cross-sections is created by varying the amount of material in the cross-section or by, more accurately, removing material in the second cross sections to make the second cross-sections more flexible by creating holes.
1. A bat having a sleeve having a taper end and a distal end, the sleeve comprising:
a first cross-section and a pair of second cross-sections adjacent to each end of the first cross section, the sleeve having first holes in each of the second cross sections and the first cross-section being solid; and
wherein the sleeve further comprises a third cross-section on the side of each of the second cross-sections distal from the first cross section, the sleeve having second holes in each of the third cross sections that are more numerous than the first holes.
2. The bat of claim 1 wherein the sleeve further comprises a fourth cross-section on the side of each of the third cross-sections distal from the first cross section, the sleeve having third holes in each of the third cross sections that are more numerous than the second holes.
3. The bat of claim 1 wherein the holes decrease in depth from the ends to the first cross section.
4. The bat of claim 1 further comprising the first cross-section being a first ring and the second cross-sections being second rings.
5. The bat of claim 4 further comprising an envelope for holding the sleeve proximal the barrel portion.
6. A bat having a sleeve having a taper end and a distal end, the sleeve comprising:
a first cross-section and a pair of second cross-sections adjacent to each end of the first cross section, the sleeve having first holes in each of the second cross sections and the first cross-section being solid;
wherein the sleeve further comprises a third cross-section on the side of each of the second cross-sections distal from the first cross section, the sleeve having second holes in each of the third cross sections that are larger than the first holes; and
wherein the sleeve further comprises a fourth cross-section on the side of each of the third cross-sections distal from the first cross section, the sleeve having third holes in each of the third cross sections that are larger than the second holes.
7. A bat having a sleeve having a taper end and a distal end, the sleeve comprising:
a first cross-section and a pair of second cross-sections adjacent to each end of the first cross section, the sleeve having first holes in each of the second cross sections and the first cross-section being solid: and
wherein the first cross-section is attached to the bat but the second cross-section is not.
8. A bat having a sleeve having a taper end and a distal end, the sleeve comprising:
a first cross-section and a pair of second cross-sections adjacent to each end of the first cross section, the sleeve having first holes in each of the second cross sections and the first cross-section being solid: and
wherein the first cross-section is adhered to the bat but the second cross-section is not.
9. A bat having a barrel portion and a sleeve, the sleeve comprising:
a solid first cross-section having a consistent external circumference; and
a second cross-section on each side of the first cross section, each second cross-section having first holes;
wherein the sleeve further comprises a third cross-section adjacent to each of the second cross-sections distal from first cross-section, each the third cross-section having second holes larger than the first holes; and
wherein the sleeve further comprises a fourth cross-section adjacent to each of the third cross-sections distal from second cross-sections, each the fourth cross-section having third holes larger than the second holes.
10. A bat having a hitting portion, a taper portion and a distal portion, the hitting portion comprising:
a first cross-section and a pair of second cross-sections adjacent to each end of the first cross section, the hitting portion having first holes in each of the second cross sections and no holes in the first cross-section; and
wherein the hitting portion further comprises a third cross-section on the side of each of the second cross-sections distal from the first cross section, the hitting portion having second holes in each of the third cross sections that are more numerous than the first holes.
11. The bat of claim 10 wherein the hitting portion further comprises a fourth cross-section on the side of each of the third cross-sections distal from the first cross section, the hitting portion having third holes in each of the third cross sections that are more numerous than the second holes.
12. The bat of claim 10 wherein the hole decreases in depth from the ends to the first cross section.
13. The bat of claim 10 further comprising a sleeve.
14. A bat having a hitting portion, a taper portion and a distal portion, the hitting portion comprising:
a first cross-section and a pair of second cross-sections adjacent to each end of the first cross section, the hitting portion having first holes in each of the second cross sections and no holes in the first cross-section;
wherein the hitting portion further comprises a third cross-section on the side of each of the second cross-sections distal from the first cross section, the hitting portion having second holes in each of the third cross sections that are larger than the first holes; and
wherein the hitting portion further comprises a fourth cross-section on the side of each of the third cross-sections distal from the first cross section, the hitting portion having third holes in each of the third cross sections that are larger than the second holes.
15. A bat having a hitting portion, a taper portion and a distal portion, the hitting portion comprising:
a first cross-section and a pair of second cross-sections adjacent to each end of the first cross section, the hitting portion having first holes in each of the second cross sections and no holes in the first cross-section; and
a sleeve, wherein the first cross-section is attached to the sleeve but the second cross-section is not.
16. A bat having a hitting portion, a taper portion and a distal portion, the hitting portion comprising:
a first cross-section and a pair of second cross-sections adjacent to each end of the first cross section, the hitting portion having first holes in each of the second cross sections and no holes in the first cross-section; and
a sleeve, wherein the first cross-section is adhered to the sleeve but the second cross-section is not.
