Appeal No. 97-0767
Application No. 08/383,996
The appellant’s invention pertains to an air-pressurized
baseball bat. Independent claim 10 is further illustrative of
the appealed subject matter and reads as follows:
10. An 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 hollow striker section defined by a shell of thin,
flexible synthetic plastic film material impermeable to air
having a shape and size similar to that of a striker section of a
conventional baseball bat;
B. a handle section joined to the striker section;
and
C. a valve mounted on the bat through which air is injected
into the striker section to produce a compressed air change
therein 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 causing a ball impinging
thereon to rebound and be driven a relatively long distance.
