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.

Claims

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.

2. Baseball batting practice apparatus as set forth in claim 1 in which said first means operates to randomly select which of said groups of light-emitting devices is actuated.

3. Baseball batting practice apparatus as set forth in claim 1 in which said second means also indicates which section of said line drive zone has been actuated.

4. Baseball batting practice apparatus as set forth in claim 1 in which said outgoing beams of said light-emitting devices are directed from said line drive zone.

5. Baseball batting practice apparatus as set forth in claim 1 in which said ground ball zone is inclined in said first direction and downward from said line drive zone, and said fly ball zone is inclined in said first direction and upward from said line drive zone.

6. Baseball batting practice apparatus as set forth in claim 1 in which said pickup means comprises a plurality of light sensors;

each of said light sensors comprising a light detector and a wide angle lens arranged to direct reflected light from a wide angle of incidence onto the light detector, whereby the overall number of light sensors may be minimized.

7. 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;

first means to actuate at least one of said light-emitting devices at a time;

second means to indicate which of said pickup means has received reflected light; and

said pickup means comprising a plurality of light sensors;

each of said light sensors comprising a light detector and a wide angle lens arranged to direct reflected light from a wide angle of incidence onto the light detector, whereby the overall number of light sensors may be minimized;

said first means also controlling the duration that said light-emitting devices are on so as to simulate speed of a pitched ball.

8. Baseball batting practice apparatus as set forth in claim 7 in which said first means operates to randomly choose which of said light-emitting devices is actuated.

9. Baseball batting practice apparatus as set forth in claim 7 in which said first means operates to actuate a group of said light-emitting devices in a predetermined sequence to simulate a non-straight pitched ball.

10. 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 at least one of said light-emitting devices at a time;

second means to indicate which of said zones contains a pickup means that has received reflected light;
