MODIFIED BALL AND BALL-SUSPENDING DEVICE

机译:改进的球和悬球装置

摘要

A device for practicing striking a standard sports ball that also has means to be held, particularly by magnetic or magnet-attractable materials located beneath the ballcover and not exposed to the atmosphere. The ball is usually retained on a minor portion of the upper 75 percent (relative to vertical) of the outer surface of the suspended ball so that its propelled trajectory and the striker's path are essentially not hindered before, during and after the strike and release against gravity and released upon sufficient impact. A ball contains means for both retaining and releasing itself from a mating pivotable, attachment arm that is generally downwardly supported to allow the ball to be suspended above the ground, be struck, released and propelled in a preferred downward trajectory, e.g. a volleyball spike. The ball is usually retained on a minor portion of the upper 75 percent (relative to vertical) of the outer surface of the suspended ball so that its propelled trajectory and the striker's path are essentially not hindered before, during and after the strike and release.
