Abstract
An adjustable moment of inertia ball bat has a hollow outer ball bat shell defining an interior cavity having an open distal end. A central shaft is disposed in the interior cavity and a weight is disposed on the central shaft. The central shaft passes through and operatively engages the weight. An interior support secures an inner end of the central shaft and a bat end cap is adapted to be fitted into the open distal end of the ball bat shell. The weight moves in the ball bat shell on the central shaft to operatively adjust a moment of inertia of the ball bat.
Claims22
An adjustable moment of inertia ball bat comprising:
- a hollow outer ball bat shell defining an interior cavity having an open distal end;
- a central shaft disposed in said interior cavity;
- a weight disposed on said central shaft, said central shaft, passing through and operatively engaging said weight;
- an interior support securing an inner end of said central shaft;
- a bat end cap adapted to be fitted into said open distal end of said ball bat shell;
- and
- means for moving said weight in said ball bat shell on said central shaft to operatively adjust a moment of inertia of said ball bat.
An adjustable moment of inertia insert for a ball bat, said insert comprising:
- a cylindrical tubular housing defining internal threads;
- an externally threaded, at least partially cylindrical weight disposed in said cylindrical tubular housing, external threads of said weight operatively engaging said internal threads of said cylindrical tubular housing;
- a central shaft passing through and longitudinally slideably, rotationally engaging said weight;
- an interior support disposed in an interior end of said cylindrical tubular housing, said interior support rotatably securing an inner end of said central shaft;
- and
- a bat end cap adapted to be fitted into an outer end of said cylindrical tubular housing and a open distal end of a hollow ball play bat.
An adjustable moment of inertia game play ball bat comprising:
- a hollow outer ball bat shell defining an interior cavity having an open distal end;
- a cylindrical tubular housing defining internal threads disposed in said interior cavity;
- an externally threaded cylindrical weight disposed in said cylindrical tubular housing, external threads of said cylindrical weight operatively engaging, said internal threads of said cylindrical tubular housing;
- a central shaft passing through and longitudinally slideably and rotationally engaging said cylindrical weight;
- an interior support disposed in an interior end of said cylindrical tubular housing, said interior support rotatably securing an inner end of said central shaft;
- and
- a bat end cap adapted to be fitted into an outer end of said cylindrical tubular housing and said open distal end of said ball bat shell.
A method comprising:
- rotating a weight of a game play ball bat insert, moving said weight along a central shaft to a second position, thereby operatively adjusting a moment of inertia of said game play bat.
A method comprising:
- rotating a central shaft of a game play ball bat insert, thereby rotating an externally threaded weight, in a cylindrical tubular housing of said insert on internal threads defined in an inner wall of said housing, moving said weight in said housing and in said ball bat shell, along said central shaft to operatively adjust a moment of inertia of said game play bat.
