  • Baseball hitting instructional device
    Patent number: 5037094
    Abstract: A base containing regulatory foot placement devices upon which a hitter stands when hitting a pitched ball. The ball of the back foot is rotated upon a revolving disc as the heel is lifted to clear a small barrier as the foot turns. An adjustable stride regulator prevents an overstride of the front foot, while an adjustable stride guide requires the front foot to reach the proper destination in relation to home plate. A scale records stride length and directional arrows indicate optimal back foot pivot per pitch location.
