  • Patent number: 6077170
    Abstract: A golf ball retrieval attachment includes an elastic sheath having an opening for receiving the head of a golf iron therein, the sheath being removably secured to the head by stretchable attachment thereabout. A semi-rigid elongated tongue is attached to the underside of the sheath and extends parallel to the shaft of the golf iron. The tongue includes a ball retrieval member having a cylindrical bore therethrough. The retrieval member further includes a flexible rim which allows a golf ball to pass thereby into the bore upon minimal pressure by the rim upon the ball. The bore is decreasingly tapered such that a golf ball entering the bore is securely held between the rim and the more narrowly tapered end of the bore. Downward pressure upon the retrieval attachment causes the tongue to bend such that the retrieval member can vertically engage the top of a golf ball. Thus, a golf ball may be retrieved through a lateral scooping motion or by bending the tongue in a vertical cup-like motion.
