Abstract

A bat, constructed generally of the shape, weight and material usually used and formed for the batter is provided so as to have a small diameter stream of light extended through the central axis from one end to the other. The formation of the light stream emitting out the knob end of the bat will allow the batter to correctly align the knob of the bat with the ball during the initial movement of a swing. The batter and his/her coach will then be able to determine if there are errors in the player'"'"'s angular position of the bat relative to the ball.

Claims

1. A training device for baseball hitters comprising a bat having a head and a handle, a source of light arranged within said bat to emit at least from said handle a beam of light along an axis central to the longitudinal axis of said bat, the bat having means with said bore to transport said light from said source of light to the ends of said bore, at least one pair of spaced openings extending from said bore transverse of the central axis and extending to the peripheral surface of said bat to define the “

sweet spot”

of said bat body.

2. The training device according to claim 1, wherein said source of light emits a beam of light from said head simultaneously with the beam from said handle.

3. The training device according to claim 1, wherein said bat is formed with an elongated bore from end to end and houses within said bore the source of said light beam.

4. The training device according to claim 3, wherein said source of light comprises at least a battery and a light bulb located on the interior of said bat connected there between a switch positioned exterior to the bat and connected with at least the battery and light.

5. The training device according to claim 4 and lens means extending from said bulb to the end of said bore to emit said light.

6. The training device according to claim 1, having transport means for the light source within said bore to transport said light from said source of light to the ends of said bore.

7. The training device according to claim 6, wherein said transport means comprise optic cable fiberglass thread, glass threads or laser wire.
