US Patent 7874946 Baseball bat with multiple reinforcing beams

A bat for limiting the maximum barrel response at high impact speeds while minimizing the dampening performance at low impact speeds includes a plurality of separate longitudinal beams extending from the end of the bat to the tapered portion of the bat. These beams, as well as the tapered portion and a handle, are constructed from a composite material, such as fiber reinforced plastic. An external sleeve is then provided around the barrel portion of the bat. The external sleeve is secured around the barrel of the bat using a snap-fit end cap.
