  • Patent number: 5338035
    Abstract: A practice golf club is presented. In accordance with the present invention, the practice golf club comprises upper and lower shafts connected by a one-way hinge. The one-way hinge is located near the lower end of the club. The upper shaft has a grip at its upper end and the lower shaft has a head at its lower end. The hinge is designed to break or pivot rearwardly at an angle relative to the reference plane of the club face. The reference plane of the club face is defined as the plane in which the club face of an iron having a 0.degree. loft lies. This angle is from 0.degree. (i.e., in the reference plane of the club face) to about 45.degree.. During use of this practice club, the hinge will pivot mirroring the correct wrist position of the golfer during a correct golf stroke. Therefore, during the backswing of a correct swing, the hinge will break or pivot and remain so pivoted through most of the downswing as will the golfer's wrist.
