  • Patent number: 4344624
    Abstract: A practice putting trainer for golfers is disclosed. The practice putting trainer of the present invention comprises an elongated, narrow, planar base having a width substantially equal to the diameter of a golf ball and sufficient stiffness to support a golf ball without perceptible deflection with a putting surface along its upper surface. A cup for receiving the golf ball is positioned at one end of the base. A ball rest for retaining the golf ball on the putting surface until struck by a putter is included on the bases. The ball rest is adjustably positioned along the length of the base to vary the length of the putt. A recess is provided in a forward edge of the ball rest to prevent transverse movement of the ball until struck by a putter.

  • Patent number: 4343473
    Abstract: A golf swing trainer includes a hand grip and a shaft formed of a limp, flexible material which is connected to the grip at one end. The free end of the shaft is unravelled to form a soft tassel. In the preferred embodiment, the shaft is formed of a soft flexible nylon rope having a diameter of approximately 0.5 inch, and the characteristics of the rope are such that the rope will extend to a straight, stiffened form to create the feel of a correctly swung golf club only when the golf swing trainer is swung through the hitting area at a predetermined velocity and timing. The hand grip is, in one embodiment, constructed of a rigid material having an outer layer of a molded high friction material adhered thereto. Alternately, the entire hand grip is formed of the molded flexible material to form a flexible grip.
