Abstract

An inertia-based baseball bat swing indicator, whether built into a baseball bat or retrofitted onto an existing bat, which visually indicates by inertia-propelled beads in separate grooves along the apparatus whether the alignment and body mechanics of the batter are proper during the bat swing.

Claims

1. A training device kit for baseball players to train themselves in the proper way to swing a baseball bat comprising

a baseball bat having a barreled head and a handle;

and

a training apparatus for indicating the proper way to swing said bat;

wherein said training apparatus is integral to said bat or separately attachable to said bat;

wherein said training apparatus comprising a grooved portion parallel to the longitudinal axis of said bat and a separate bead which rests in said grooved portion of said training apparatus and freely moves within said grooved portion of said training device when the bat is swung.

2. The device in claim 1, wherein said groove path comprises an upper groove path and a lower groove path.

3. The device in claim 2, wherein said upper groove path and said lower groove path form a lateral Y shape groove path.

4. The device in claim 2, wherein said ball will enter said lower groove when a batter properly swing said baseball bat.

5. The device in claim 2, wherein said bead will enter said upper groove when a batter incorrectly swings said baseball bat.

6. The device in claim 2, wherein said bead moves within said upper and said lower groove based on the inertia profile created by a batter'"'"'s swing.

7. The device in claim 1, wherein said groove path comprises main tube path, an upper tube path and a lower tube path.

8. The device in claim 7, wherein said bead will enter said lower tube path when a batter properly swings said baseball bat.

9. The device in claim 7, wherein said bead will enter said upper tube path when said a batter incorrectly swings said baseball bat.

10. The device in claim 1, wherein said kit further comprises a grip-positioning molded grip.

11. The device in claim 10, wherein said grip is specifically molded wherein a batter'"'"'s hands are properly aligned with each other wherein said batter can manipulate said baseball bar properly when attempting to hit the baseball and said batter'"'"'s knuckles are properly lined up.
