TRAINING BAT WITH VISUAL FEEDBACK OF PROPER SWING
First Claim
Patent Images
1. A baseball training bat comprising:
- a handle and a barrel, the barrel having an end distanced from the handle, a channel being formed in the barrel from the end of the barrel and extending toward the handle;
a first magnet within the channel, the first magnet riding axially on a lead screw within the handle to a user-desired location; and
a movable magnet disposed in the channel for translational movement between a housed position, wherein the movable magnet is adjacent the first magnet and wherein magnetic attraction holds the movable magnet in the housed position, and a swung position, toward which the movable magnet moves when sufficient centrifugal force is imparted to the movable magnet to overcome the magnetic attraction between the magnets.

Abstract
A training baseball bat has an internal movable magnet that accelerates to the end of the bat when swung at a fast enough speed. As the magnet moves it passes through a coil that is connected to one or more LEDs so that the LEDs momentarily flash as the magnet moves through the coil. An axially positionable stationary magnet can be used to hold the movable magnet until sufficient centrifugal force is imparted by the swing to overcome the magnetic holding force.

10. A baseball training device comprising:
-
a handle connected to a barrel, the barrel having an end distanced from the handle, a channel being formed in the barrel from the end of the barrel and extending toward the handle; a movable magnet disposed in the channel; a first magnet assembly including a first magnet for urging the movable magnet toward a housed position, wherein the movable magnet can move between the housed position and a swung position when sufficient force is imparted to the movable magnet to overcome the first magnet; and an adjustment assembly threadably engaged with the first magnet assembly and rotatable by a person to establish an axial location of the first magnet. - View Dependent Claims (11, 12)
