  • Patent number: 10960287
    Abstract: A pendulum stroke teaching device formed from a one piece coupling element for use with conventional golf alignment sticks and an individual's putter club. The coupling element includes two spaced apart apertures for receipt of the distal ends of the alignment sticks. A centrally disposed cavity between the apertures is constructed and arranged for receipt of a putter shaft. The coupling element operates to secure the alignment sticks and putter in a fixed position. The ends of the alignment sticks are placed between the torso and the inner upper arms of the golfer. When the golfer grasps the putter grip, movement of the putter can only take place by use of a pendulum stroke. The teaching device is used for training the golfer to use a repetitive and consistent swing for improving their golf experience.

  • Patent number: 7744479
    Abstract: A portable golf practice game consisting of a wall having a front face, rear face, and base. The wall includes a plurality of openings along the base for the entry of an object there-through. Each opening includes an opening sensor to detect the presence of an object there-through. The wall further includes proximity sensors along the base to detect the presence of an object not passing though an opening. The sensors emit a signal which is detected by a processor connected to the wall. Each opening has a corresponding graphic element which displays a value interpreted by the processor. A user chooses a game on the input device, then propels an object toward the wall, a sensor emits a signal, the processor interprets the signal and the graphic element displays an assigned value.
