  • Patent number: 4629188
    Abstract: A baseball target device is disclosed wherein the device includes a target that is adjustable in height and length to simulate the strike zones of different size batters. In the preferred embodiment, the device utilizes a base to which a telescopically adjustable vertical frame is attached, wherein the frame supports an adjustable spring-loaded window shade device. The shade of this device hangs down from the frame and its unrolled portion defines a "strike zone" for the pitcher. A picture of a crouched catcher and umpire is imprinted on the shade to give the target a realistic effect. The pitcher may adjust the target to the size of the strike zone for a particular batter by adjusting the telescopic frame to the height of the batter's shoulder and then adjusting the target shade to the batter's knee, thus creating a target whose size and location simulates the exact strike zone for that particular batter.
