发明名称 Ball striking practice apparatus
摘要 A ball striking practice apparatus comprises a lower anchor means, an upper anchor means and an intermediate anchor means horizontally spaced relative to the aforementioned anchor means but defining therewith a vertical plane which normally is bisected by the body of the person utilizing the practice device. A practice ball is positioned between the aforementioned three anchor elements by three elastic cords. The ball is diametrically traversed by a wire having looped ends on the exterior of the ball which provide anchoring means at the top and bottom surfaces of the ball. A horizontal, radially disposed wire is inserted into the ball and has a hooked end engaging the center of the diametrical wire. The radially disposed wire defines a looped end exteriorly of the ball and positioned radially intermediate the top and bottom loop ends. Each of the looped ends. Each of the bolt elements defines an anchor for one of the elastic cords and the three elastic cords are respectively secured to the lower anchor means, the upper anchor means and the intermediate anchor means to thereby position the ball for striking by a player. The ball will rapidly return to its initial position without engaging in a flight path that would threaten the player after the practice ball is hit.
