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.
A light-weight, air-pressurized baseball bat useable by children to strike an oncoming ball so that it is driven a relatively great distance; said bat comprising: A. a striker section defined by a shell of thin, flexible synthetic plastic film material to create an enclosed envelope impermeable to air having a shape and size similar to that of a striker section of a conventional baseball bat, said shell being provided with a one-way valve through which air is injected to produce in the envelope a compressed air charge well above atmospheric pressure whereby the charge of compressed air acts as a pneumatic spring and said shell acts as a taut spring-loaded trampoline sheet thereby causing a ball impinging thereon to rebound and be driven a relatively great distance; B. a handle section; and C. a coupler joining the handle section to the striker section to complete the bat, said valve being formed by a rubber plug which is penetrable by a hypodermic needle to inject compressed air in said envelope, said shell being provided at a lower end with a half neck in which the valve is installed.
