  • Patent number: 6994633
    Abstract: A method and device for golf swing training is disclosed wherein a double pendulum model swing is replicated by defining a point on a golfer's chest about which a golfer's swing rotates and extending therefrom a inelastic flexible strap for attachment to the grip of a golf club. The inelastic flexible strap encourages the golfer to fully extend his arms throughout the golf swing to maintain a proper swing radius without inhibiting the movement of the golfer's wrists; therefore, allowing the golfer to experience the ideal golf swing.
    Type: Grant

  • Patent number: 6955610
    Abstract: An apparatus is provided that allows individuals of diverse skill levels to improve their respective sports-related swings. The apparatus provides visual, auditory and tactile feedback as to whether an individual is correctly “loading”, “retaining”, and “releasing” the inherent power of the training apparatus. The training apparatus enables an individual to fine tune his/her swing to maximize power delivery, e.g., in driving a golf ball, striking a hockey puck, or hitting a baseball. A slidable member is provided that moves along a shaft between an upper member and a lower member. A retaining mechanism restrains the slidable member in a cocked position, i.e., in juxtaposition with the upper member, until a predetermined force is created through swinging of the shaft.
