Abstract

A laser beam strike zone indicator including a home plate. A plurality of adjustable laser beams are directed upwardly from the home plate to define a strike zone for a height of a predetermined batter.

Claims

1. A laser beam strike zone indicator for establishing an electronic strike detection zone for baseball and softball comprising, in combination:

a home plate having a front portion and a back portion, the front portion having a square configuration and the back portion having a triangular configuration, a base of the back portion integral with a rear edge of the front portion, the home plate further being defined by five corner points, the five corner points including two front points, two intermediate points and a single rear point; and

a plurality of adjustable laser beams comprising two front beams, two intermediate beams and two rear beams, the two front beams disposed within the two front points of the home plate, the two intermediate beams disposed within the intermediate points of the home plate, the two rear beams disposed within the single rear point of the home plate, the two front beams directed upwardly to a height of a batter'"'"'s armpits in an orthogonal relationship with respect to opposing sides of the home plate, the two intermediate beams directed angularly upwardly to intersect the two front beams at a height of the batter'"'"'s knees, the two rear beams directed angularly upwardly to intersect the two front beams at the height of the batter'"'"'s armpits.

2. A laser beam strike zone indicator for establishing an electronic strike detection zone for baseball and softball comprising:

a home plate, the home plate further being defined by five corner points, the five corner points including two front points, two intermediate points and a single rear point,

a plurality of adjustable laser beams directed upwardly from the five corner points of the home plate to define a strike zone for a height of a predetermined batter, the plurality of adjustable laser beams comprising two front beams, two intermediate beams and two rear beams, the two front beams disposed within the two front points of the home plate, the two intermediate beams disposed within the intermediate points of the home plate, the two rear beams disposed within the single rear point of the home plate.

3. The strike indicator as set forth in claim 2 wherein the two front beams directed upwardly to a height of a batter'"'"'s armpits in an orthogonal relationship with respect to opposing sides of the home plate, the two intermediate beams directed angularly upwardly to intersect the two front beams at a height of the batter'"'"'s knees, the two rear beams directed angularly upwardly to intersect the two front beams at the height of the batter'"'"'s armpits.
