Abstract: Ball bats comprising a stem and a handle surrounding the stem. An elastomeric decoupler system installed in the handle sharply reduces the transmission of shocks and vibrations from the stem to the handle, mitigating stinging and other unpleasant sensations experienced by the batter when a ball is struck. Unpleasant sensations can be further reduced by installing a DTMS damping device in the knob of the bat and by installing an elastomeric grip on the handle of the bat; and the unpleasant sound made when a bat strikes the ground or the like can be materially reduced by a device attached to the stem of the bat intermediate the ends of the handle. The present inventions are particularly adaptable to hollow, metal bats; and provision is made for venting the knob of the bat when it is welded in place so hot gases will not be forced into, and reduce the integrity of, the weld. Appropriate ones of the devices described above may also advantageously be employed in wood, composite, and other bats.

Abstract: The present technology relates to laminated ball bats and a methodology for making the same. The disclosed technology provides for a laminated blank suitable for machining into a laminated bat having a generic bat shape (such as a bat consisting of a handle and a barrel where the handle has a smaller diameter than the barrel) that offers greater flexibility in changing the bat's weight distribution. Using lamination technology, various portions of a blank may be constructed having different densities (and associated weights) thereby decoupling such blank's length/weight properties. Such technology provides a method of positioning a bat's center of mass (CM) at various locations along the bat thereby changing the location of the bat's sweet spot zone center. Bats constructed in accordance with the disclosed technology may have a variety of pre-selected weight distributions while maintaining a particular bat shape and a particular overall bat weight.
