发明名称 Ball hitting practice device
摘要 A ball hitting practice device including a supporting base, a vertical support post, and an elongated support bar pivotally attached to the support post for movement between operative and inoperative positions. A protective net is supported in cantilevered relationship to the elongated support bar so that a major portion of the net extends downwardly toward the ground at a distance away from the support bar. A ball, which may be a baseball, softfall or tennis ball is suspended by means of a cable from the elongatged support bar, and is provided with a visual indicator, such as a fluorescent stripe about its middle portion, to aid the user of the device. The cable may also be provided with a kinetic energy damping device to more effectively control the ball and to reduce the interval between successive swings at the ball.
