发明名称 Training device for baseball hitters
摘要 A training device for baseball or softball hitters is provided having a firm belt for encircling the chest of a hitter, and a separate firm belt for encircling the upper portion of the lead arm of the hitter, with the two belts being firmly secured together so as to bind the hitter's upper lead arm tightly to his side while leaving his forearm generally free for movement throughout an entire swing of the bat. Using this training device, when the hitter begins to swing at a pitched ball, the upper portion of his lead arm and elbow becomes "locked in" close to his side, and remains so locked throughout the entire swing. The training device thus promotes desirable hip action and "tophand action" produced by the swinging motion of the hitter's body, thus generating more power in the swing.
