Abstract

Abstract A device for striking a ball, such as a soft foam rubber ball, includes a ball striking element including a clear transparent shell portion which is formed in a configuration similar to a device such as a golf club or a baseball bat and a colored liquid in an inner cavity in the shell portion. The colored liquid only partially fills the inner cavity in the shell portion so that it not only acts to transfer weight in the device during a ball striking exercise but to also provide a unique splashing visual effect.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 148 words
A device for striking a ball comprising: a. a ball striking element configured to resemble a baseball bat including a hitting portion and a handle portion, said ball striking element comprising a hollow transparent plastic shell defining said hitting portion and forming a hollow tubular inner core for said handle portion, said plastic shell defining an enclosed hollow cavity which extends substantially without restriction through substantially the entire length of said ball striking element, and opaque gripping means on said inner core for said handle portion; and b. a fluid material in said cavity, said fluid material only partially filling said cavity, said fluid material being visible form the exterior of said ball striking element and flowing freely and without restriction in said all striking element from one end of said cavity to the other end thereof to provide an amusing visual effect during swinging of said device.
