BAT WITH BIFURCATED INTERNAL CAVITIES

摘要

A tubular bat is provided whereby at least one diaphragm is located within the internal cavity of the bat. The diaphragm is fastened at its peripheral edge to the inner surface of the bat wall, thereby dividing the internal cavity into two separated cavities, thus creating two sweet spots, or shifting the existing sweet spot forward towards the distal end of the bat. This improves player performance by providing an expanded number of optimal hitting zones or by moving the optimal hitting zone farther from the bat handle.

主权项

1. A tubular bat for striking a ball, the bat comprising:
a handle portion configured to be held by a player; a tubular barrel portion configured to strike the ball, the tubular barrel portion having a bat wall having an inner surface and an outer surface and defining an internal cavity with an internal diameter; a tubular taper portion connecting the handle portion and the barrel portion; and at least one diaphragm located within the internal cavity, the at least one diaphragm having a peripheral edge mounted to the inner surface of the bat wall, thereby dividing the internal cavity into at least two cavities, the at least one diaphragm comprising an outer U-shaped ring portion, an inner disc portion, and an annular gap located between the outer U-shaped ring portion and the inner disc portion;wherein, in use, upon contact with the ball, the at least one diaphragm is configured to deform by a predetermined amount before its outer U-shaped ring portion contacts its inner disc portion for providing a limited trampoline effect to the bat.
