发明名称 Basketball practice apparatus
摘要 A target practice apparatus for improving the shooting accuracy of a basketball player is releasably mounted to a basketball goal to present a target clearly above the rim and aligned along a vertical centerline of the horizontal plane containing the rim. The target also contains a point of a desired curvilinear path of a shot basketball between the player and goal. Upon proper contact by a shot basketball, the target swings to a position away from the desired path to allow passage of the basketball through the underlying goal. The displaced target is spring biased towards its centerline position so as to offer a proper and easily viewed aiming point awaiting the next shot of the player.
