  • Patent number: 5358250
    Abstract: A golf club swing training aid is disclosed which includes a waist belt, a ground mountable frame adapted to extend vertically to about a waist-high level relative to a golfer using the aid, and an elastomeric cord connected on one end to a medial position on the back of the belt when the belt is worn by the golfer in an operative waist encircling position. The frame contains a pair of spaced apart, parallel extending legs adapted for mounting in the ground immediately laterally adjacent the golfer when standing in a position to properly address a golf ball with a golf club such that the legs of the frame are aligned with the legs of the golfer parallel to the intended line of flight of the golf ball. The other end of the cord is removably attachable to an eye bolt affixed to an upper end of one of the frame legs. The frame may include an inverted U-shaped upper section made of hollow aluminum alloy tubing and an H-shaped lower section made of rigid steel rods.
