ABSTRACT:
A ball retrieving storage device including an elongated hollow tube opened at one end for reception of a ball, the tube having formed in the opened end a circumferential groove concentrically arranged therewith opening inwardly toward the hollow interior of the tube and defined by upper and lower groove side surfaces, a yieldable ring of measured thickness concentrically located in the groove, the ring having an internal diameter slightly smaller than the outside diameter of the ball to be retrieved, wherein the groove is wider than the thickness of the ring to allow the ring to be moveable therein and displacable upward therein in response to the upward pressure of a to-be-retrieved ball from below when the opened end of the tube is passed over the ball, and wherein the groove has a first depth, in the area of natural repose of the ring, and a second depth in the area of the upward displacement thereof, wherein the second depth is greater than the first depth to allow the ring to expand under the upward pressure of the ball and allow passage of the ball therethrough into storage in the tube and to prevent the ring from thereafter expanding under downward pressure of the ball and bar retractive passage of the ball out through the tube opened end.
