Abstract
A light-weight, air-pressurized baseball bat useable by children to strike a ball, the bat having an enhanced striking power. The bat comprises striker and handle sections joined together by a coupler. The striker section is defined by a shell of synthetic plastic material whose shape is similar to that of a standard two-liter soda bottle. The shell is adapted to envelop a charge of compressed air and is provided with a half neck in which a valve plug is installed whose inlet projects therefrom. The handle section is provided at its upper end with a half neck that complements that of the striker section, the two-half necks being clamped together by the coupler which has a port therein to accommodate the valve inlet. By injecting compressed air into the striker section through the valve, the compressed air enveloped by the shell functions as a trampoline which when the ball impinges on the shell then acts to boost the rebound of the ball, thereby enhancing the striking power of the bat.
