Publication number: 20130014307Abstract: A golf glove is disclosed with a circular contact patch designated, with biomechanical precision, in the centre of the palm that indicates a neutral hand position. In the modern, total body golf swing, where the rotating torso is the major power generator of the golf swing, the arms and hands are flung around, and in front, of the rotating body during the downswing. The primary function of the hands is to hold onto the clubshaft in such a manner that the clubface will be allowed to become square to the ball-target line at the time of impact, and this feat is best accomplished if the hands are in the neutral position.Type: ApplicationFiled: June 26, 2012Publication date: January 17, 2013Inventor: Jung Ki Lee
