  • Patent number: 4834370
    Abstract: Tubular baseball bats are provided with optimized power zones by weighting the bats between the impact and the knob end. By adding a specified amount of weight at a location within this weighting region, the sweet spot of the bat, in effect, may be greatly enlarged so that the sweet spot comprises a power zone extending inwardly from the outer end of the bat. The power zone therefore comprises the portion of the bat which travels at maximum velocity as the bat is swung into the ball, and the ball impacts within the power zone effectively transfers less than 10% of the impact impulse to the hands. The hit ball therefore travels faster and further.
    Type: Grant

    Date of Patent: May 30, 1989
