Ball bat with shock attenuating handle
First Claim
1. A ball bat comprising a barrel portion, a handle, and a joint connecting the barrel portion to the handle, the joint comprising:
- a rod element extending from the handle and into the barrel portion; and
a filler material in the handle and the barrel portion, the filler material at least partially surrounding the rod element within the handle and within the barrel portion and spanning a gap between the barrel portion and the handle, wherein the filler material extends at least as far as the rod element into the handle or into the barrel portion.

Abstract
A ball bat includes a first bat portion (such as a barrel portion) and a second bat portion (such as a handle). The portions may be spaced apart along the bat'"'"'s longitudinal axis. A joint connects the first and second bat portions. The joint may be positioned at or near, or centered about, a location of maximum vibration, such as an antinode of the bat. The joint may include a filler material (such as an elastomeric material) at least partially surrounding a rod element. The filler material and the rod element may span a gap between the first and second bat portions. The filler material and the rod element may extend into the first bat portion or the second bat portion. A cover material may be positioned around the filler material. The joint may form a structural link between the bat portions and it may be configured to absorb vibration.
