  • Patent number: 6001033
    Abstract: A putting aid comprising two arms converging to an apex such that an acute angle is formed therebetween is herein described. The two arms have inner faces that include markings, such as a center stripe opposite the apex, that act to improve the visibility of the putting aid. Specifically, the putting aid is arranged to be positioned on a putting green such that the golf cup is between the two arms and the center stripe is approximately four inches behind the golf cup. The putting aid is then oriented such that the apex is opposite the direction of putting relative to the golf cup. The golfer then uses the center stripe as a target when aiming for the golf cup. As a result of this arrangement, the location of the golf cup is more visible and a golfer aiming for the center stripe will tend to putt harder, that is, so that the putt will travel approximately four inches further. The end result is a stronger and more accurate putt.

  • Patent number: 5984797
    Abstract: A golf swing training system with a floor mounted base and a pelvic belt that wraps around the golfer's hips and guides but not unduly restricts the golfer's pivot during the back swing and follow through. The system encourages a pelvic pivot about an axis to the rear of the golfer's right leg in the back swing and down swing, and a pivot about an axis behind the golfer's left leg in the follow through. A multiple pivot mechanism that connects the belt to the base inhibits lateral movement of the hips during the back swing and down swing. The belt is connected to the base by an expandable link pivotally connected at one end to the base and pivotally connected at its other end to the belt, both about generally vertical axes. As the golfer initiates the back swing, the belt pivots about the second axis as the link pivots in the opposite direction about the first axis.
