1. A ball bat extending along a longitudinal axis, the bat comprising:
- a handle portion having a proximal gripping region and a distal region, and a 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, the distal region of the handle portion not extending to the distal region of the barrel portion such that the distal region of the barrel portion does not overlap the distal region of the handle portion;
an element formed of a thermoplastic or thermoset material and non-removably attached to the distal region of the handle member, the element having a tapered proximal region, a barrel engaging region and including a tubular wall and an outer wall, the barrel engaging region of the element non-removably engaging and being overlapped by the proximal region of the barrel portion, the barrel engaging region and the proximal region of the element each having a maximum outer diameter, the maximum outer diameter of the barrel engaging region being greater than the maximum outer diameter of the proximal region of the element, the proximal region of the element having an exposed outer surface including a first texture and the barrel engaging region having an outer surface defining a second texture that is different from the first texture, the bat having a total length measured from a proximal end of the handle portion to a distal end of the barrel portion, the tubular wall of the element defining a longitudinally extending bore, the handle portion extending within the length of the bore such that at least a portion of the tubular wall of the element overlaps and engages a portion of the handle portion, the handle portion having a length that is less than 70 percent of the total length.

Abstract
A ball bat extending about a longitudinal axis. The bat includes a handle portion, a barrel portion and an injection molded element non-removably attached to the handle member. The barrel portion has a proximal region and a distal region spaced apart by a central region. The element has a tapered proximal region and barrel engaging region. The barrel engaging region of the element non-removably engages the proximal region of the barrel portion. The bat has 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.

10. A ball bat extending along a longitudinal axis, the bat comprising:
-
a handle portion having a 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 element formed of at least first and second thermoplastic or thermoset materials and non-removably attached to the handle member, the element having a tapered proximal region, a barrel engaging region and including a tubular wall and an outer wall, the barrel engaging region of the element non-removably engaging and being overlapped by the proximal region of the barrel portion and not overlapped by the central region or the distal region of the barrel portion, the barrel engaging region and the proximal region each having a maximum outer diameter, the maximum outer diameter of the barrel engaging region being greater than the maximum outer diameter of 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 tubular wall of the element defining a longitudinally extending bore, the handle portion extending within the bore such that at least a portion of the tubular wall of the element overlaps and engages a portion of the handle portion, the handle portion having a length that is less than 70 percent of the total length, the element including at least one base layer formed of at least the first thermoplastic or thermoset material, and an outer layer formed of the second thermoplastic or thermoset material. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 19)
