BAT SWING TRAINING DEVICE

摘要

A bat swing training device for enabling the diagnosis and correction of an individual batter's swing. The training device includes a conventional bat modified to receive a training aid at its distal. The training aid provides a snapping sound if an individual swings the bat at greater than a predetermined speed such that inertial forces overcome magnetic forces acting on a paramagnetic slider and the slider accelerates from a first stop to a second stop producing a snap. The position of the batter's hands at the time of the snap indicates whether the batter's swing is correct.

主权项

1. A bat swing training device for use in correcting a batter's swing comprising:
A) a conventional baseball bat with a proximal handle or grip, a barrel portion, a distal end, and an axial passage extending proximally from the distal tip barrel end into the bat to receive the training aid, B) a training device including a structure that, at a predetermined bat speed, releases a ring to slide along a proximal housing and snap against a distal stop including:
i) a shaft extending longitudinally through said training device,ii) first and second stops at longitudinally spaced positions along said shaftiii) a magnet on said shaft proximally of said first stop, C) a slider of a paramagnetic material mounted on said shaft intermediate said first and second stops that is magnetically attracted to said first stop whereby upon proper swinging the bat, inertial forces overcome the magnetic attraction and said slider accelerates to said second stop, and D) means for affixing said training aid to the bat.
