Apparatus for baseball batting practice
First Claim
1. Baseball batting practice apparatus including:
- a plurality of spaced light-emitting devices actuable to simulate a pitched ball by directing respective outgoing beams of light in a first direction to a batting zone;
said batting zone including a front facing said light-emitting devices and a rear opposite said front;
a bat having a light-reflecting portion;
a plurality of pickup means disposed forward of said batting zone to receive reflected light from said light-reflecting portion of said bat while the latter is swung in a generally forward direction through said batting zone by a player and intercepts one of said outgoing beams of light;
said forward direction being opposite said first direction;
said pickup means being divided into a line drive zone, a ground ball zone disposed below said line drive zone and a fly ball zone disposed above said line drive zone;
first means to actuate said light-emitting devices in a plurality of different groups and control the light emitting devices within each of said groups so that they are activated in a predetermined sequential-time relationship to simulate speeds and trajectories for differently thrown balls; and
second means to indicate which of said zones contains a pickup means that has received reflected light.

Abstract
A baseball practice apparatus comprised of a vertically extending panel having a plurality of selectively operable lights which generate focused light beams directed forward from the panel. A player swings a bat having a light reflecting surface which will intercept and cause the light beams to be reflected back towards the panel. On the panel there is an array of spaced light sensors. One of the light sensors detects the reflected light, and a visual indication is provided of the simulated result of the swing, for example, a "line drive" or a "fly ball". A foregoing visual display is provided in response to which light, or lights, were illuminated to simulate a pitched ball and which sensor sensed reflected light from the bat. A "curve", a "sinker" or other pitch is simulated, by actuating selected lights in a predetermined sequence.
