Patent ID: 6949038

Claim:
A ball bat configured for impacting a ball, the bat comprising: a substantially tubular frame extending along a longitudinal axis having a handle portion and a primary hitting portion; and a substantially tubular body coaxially aligned with the hitting portion of the frame, the body including a proximal end, a distal end, and first and second tubular wall transition regions, the first tubular wall transition region positioned closer to the proximal end than the second tubular wall transition region, the wall thickness of the first tubular wall transition region generally increasing along the longitudinal axis from a first position, generally near the proximal end, toward the distal end, and the wall thickness of the second tubular wall transition region generally increasing along the longitudinal axis from a second position, generally near the distal end, toward the proximal end, the body being configured to move independently with respect to the hitting portion of the frame upon impact with the ball.
