Abstract

A ball bat extending about a longitudinal axis and includes a handle portion, a barrel portion, an injection molded element, and a tubular insert. The handle portion has a generally uniform outer diameter. The barrel portion has proximal and distal regions spaced apart by a central region. The element includes a tubular inner wall defining a longitudinal bore. The element is non-removably attached to the handle member. The element includes a tapered proximal region, a barrel engaging region, and an insert engaging region for engaging the insert. The insert engaging region includes a stop for inhibiting longitudinal movement of the insert. The barrel engaging region non-removably engages the proximal region. The bat having a total length measured from a proximal end of the handle portion to a distal end of the barrel portion. The handle portion has a length that is less than 70 percent of the total length.

First claim

What is claimed is:

1. A ball bat extending along a longitudinal axis, the bat comprising:
a handle portion having a generally uniform outer diameter with respect to the longitudinal axis;
a barrel portion having a proximal region and a distal region spaced apart by a central region;
an injection molded element including an outer wall extending over at least a portion of the length of the element and a tubular inner wall defining a longitudinal bore having a uniform inner diameter, the at least a portion of the handle portion extending into, and engaging the inner diameter of, the bore, the element non-removably attached to the handle member, the element including a tapered proximal region, a barrel engaging region, and a distal insert engaging region, at least a portion of the distal insert engaging region extending from the barrel engaging region toward the distal region of the barrel portion, a portion of the outer wall of the element being visible to a user; and
a tubular insert extending along at least the proximal region and the central region of the barrel portion and engaged with the insert engaging region of the element, the insert engaging region including a stop for engaging the insert and inhibiting longitudinal movement of the insert in a proximal direction, the proximal end region of the barrel portion overlapping and non-removably engaging the barrel engaging region of the element, the bat having a total length measured from a proximal end of the handle portion to a distal end of the barrel portion, the handle portion having a length that is less than 70 percent of the total length.

2. The ball bat of claim 1 , wherein the outer wall spaced apart from the tubular wall by at least one rib.

3. The ball bat of claim 2 , wherein the at least one rib radially extends with respect to the longitudinal axis from the tubular wall to the outer wall.

4. The ball bat of claim 2 , wherein the at least one rib extends from the tubular wall to the outer wall at an angle when measured with respect to a plane extending through and along the longitudinal axis.

5. The ball bat of claim 2 , wherein the at least one rib is at least three ribs.

6. The ball bat of claim 2 , wherein the at least one rib is spiraled about the longitudinal axis.

7. The ball bat of claim 1 , wherein the element is entirely injection molded.

8. The ball bat of claim 1 , wherein the barrel engaging region of the element has a generally frustoconical shape.

9. The ball bat of claim 8 , wherein the proximal region of the barrel portion generally converges toward the longitudinal axis to form a frustoconical shape that is complementary to and telescopically engages the barrel engaging region of the element.

10. The ball bat of claim 1 , wherein the barrel engaging region of the element non-threadedly engages the proximal region of the barrel portion.

11. The ball bat of claim 2 , wherein the outer wall of the element includes at least one base layer formed of at least a first material, and an outer layer formed of a second material.

12. The ball bat of claim 11 , wherein the hardness of the first material is greater than the hardness of the second material, wherein the hardness is measured on a Shore hardness scale.

13. The ball bat of claim 11 , wherein the first and second materials are formed of different colors.

14. The ball bat of claim 11 , wherein the texture of the outer layer is different than the texture of the outer surface of the base layer.

15. The ball bat of claim 11 , wherein the outer layer is over-molded to the at least one base layer.

16. The ball bat of claim 11 , wherein the outer layer includes one or more openings enabling at least a portion of the base layer to be visible on the outer surface of the element.

17. The ball bat of claim 1 , wherein the tapered proximal region includes graphical and/or alphanumeric indicia.

18. The ball bat of claim 1 , wherein the handle portion is a pultrusion.
