Abstract

Baseball bats described herein may have handle, throat and/or barrel portions that include non-circular cross-sections.

Claims (49)

1. A bat comprising:

a body, comprising a composite material, the body defining an exterior surface with a top end and a bottom end;

a barrel portion having a barrel cross-section with a substantially circular perimeter that defines a center point;

the barrel cross-section defining a longitudinal axis substantially perpendicular to the barrel cross-section, the longitudinal axis intersecting the barrel cross-section at approximately the center point, the longitudinal axis intersecting and extending through the exterior surface, near the top and bottom ends, at respective upper and lower intersection points, and otherwise within the exterior surface;

a handle portion that includes the bottom end;

the handle portion defining a maximum forward distance, measured along a first line perpendicular to the longitudinal axis, from a first point on the longitudinal axis to a first location on the exterior surface of the handle portion that is farthest forward of the longitudinal axis;

the handle portion defining a maximum rearward distance, measured along a second line perpendicular to the longitudinal axis, from a second point on the longitudinal axis to a second location on the exterior surface of the handle portion that is farthest rearward of the longitudinal axis;

the handle portion also having an asymmetrically flared region extending from an upper boundary to a lower boundary, the upper boundary being more proximate the top end and the lower boundary being more proximate the bottom end;

the asymmetrically flared region defining a non-circular cross-section perpendicular to the longitudinal axis, the non-circular cross-section having a major axis, wherein the major axis increases continuously throughout the asymmetrically flared region, from the upper boundary to the lower boundary;

and portions of the exterior surface, in the asymmetrically flared region, defining a front edge and a rear edge, wherein the distance from the longitudinal axis to the front edge, measured along respective lines perpendicular to the longitudinal axis, is greater than the distance from the longitudinal axis to the rear edge, for each point of the longitudinal axis throughout the asymmetrically flared region.

2. The bat of claim 1 , wherein at least part of the body comprises a coating proximate at least a portion of the exterior surface.

3. The bat of claim 1 , wherein the distance from the longitudinal axis to the rear edge increases continuously throughout the asymmetrically flared region, from the upper boundary to the lower boundary.

4. The bat of claim 1 , wherein the handle portion has a region with at least one cross-section that defines a substantially circular perimeter thereof.

5. The bat of claim 1 , wherein the distance from the longitudinal axis to the front edge exceeds the distance from the longitudinal axis to the rear edge, for each point of the longitudinal axis that is within the asymmetrically flared region.

6. The bat of claim 1 , wherein the non-circular cross-section defines a perimeter having an oblong shape.

7. The bat of claim 1 , wherein the distance from the upper boundary to the lower boundary of the asymmetrically flared region occupies at least 2 inches, measured along the longitudinal axis.

8. A bat comprising:

a body defining an exterior surface with a top end and a bottom end, the body having a barrel portion that includes the top end, a throat portion, and a handle portion that includes the bottom end;

the barrel portion comprising a first material, the barrel portion having a barrel cross-section with a substantially circular perimeter that defines a center point;

the barrel cross-section defining a longitudinal axis substantially perpendicular to the barrel cross-section, the longitudinal axis intersecting the barrel cross-section at approximately the center point, the longitudinal axis intersecting and extending through the exterior surface, near the top and bottom ends, at respective upper and lower intersection points, and otherwise within the exterior surface;

the throat portion comprising a second material, the throat portion having an upper extent and a lower extent, the upper extent being more proximate the top end and the lower extent being more proximate the bottom end;

the handle portion defining a maximum forward distance, measured along a first line perpendicular to the longitudinal axis, from a first point on the longitudinal axis to a first location on the exterior surface of the handle portion that is farthest forward of the longitudinal axis;

the handle portion defining a maximum rearward distance, measured along a second line perpendicular to the longitudinal axis, from a second point on the longitudinal axis to a second location on the exterior surface of the handle portion that is farthest rearward of the longitudinal axis;

the handle portion having an asymmetrically flared region extending from an upper boundary to a lower boundary, the upper boundary being more proximate the top end and the lower boundary being more proximate the bottom end;

the asymmetrically flared region defining a non-circular cross-section perpendicular to the longitudinal axis, the non-circular cross-section having a major axis, wherein the major axis increases continuously throughout the asymmetrically flared region, from the upper boundary to the lower boundary;

and portions of the exterior surface, in the asymmetrically flared region, defining a front edge and a rear edge, wherein the distance from the longitudinal axis to the front edge, measured along respective lines perpendicular to the longitudinal axis, is greater than the distance from the longitudinal axis to the rear edge, for each point of the longitudinal axis throughout the asymmetrically flared region.

9. The bat of claim 8 , wherein the handle portion further comprises a wrapping.

10. The bat of claim 8 , wherein the distance from the longitudinal axis to the rear edge increases continuously throughout the asymmetrically flared region, from the upper boundary to the lower boundary.

11. The bat of claim 8 , wherein the distance from the longitudinal axis to the front edge exceeds the distance from the longitudinal axis to the rear edge, for each point of the longitudinal axis that is within the asymmetrically flared region.

12. The bat of claim 8 , wherein the non-circular cross-section defines a perimeter having an oblong shape.

13. The bat of claim 8 , wherein the distance from the upper boundary to the lower boundary of the asymmetrically flared region occupies at least 2 inches, measured along the longitudinal axis.

14. The bat of claim 8 , wherein the first material comprises a metal.

15. The bat of claim 8 , wherein the second material comprises resin-filled fibers.

16. A bat comprising:

a body, comprising wood, the body defining an exterior surface with a top end and a bottom end;

a barrel portion having a barrel cross-section with a substantially circular perimeter that defines a center point;

the barrel cross-section defining a longitudinal axis substantially perpendicular to the barrel cross-section, the longitudinal axis intersecting the barrel cross-section at approximately the center point, the longitudinal axis intersecting and extending through the exterior surface, near the top and bottom ends, at respective upper and lower intersection points, and otherwise within the exterior surface;

a handle portion that includes the bottom end;

the handle portion defining a maximum forward distance, measured along a first line perpendicular to the longitudinal axis, from a first point on the longitudinal axis to a first location on the exterior surface of the handle portion that is farthest forward of the longitudinal axis;
