Abstract: Techniques for training and correcting a golf swing are described. A golfer places a ball at a teeing point on a teeing surface which is tiltably adjustable about a horizontal tilt axis. A catch device is aligned with a target direction passing through the teeing point and extending perpendicularly to the tilt axis. The golfer aims along the target direction and executes a golf swing to strike the ball from the teeing point. The actual direction of travel of the struck ball is determined. An azimuth difference is determined between the target direction and the actual direction of travel of the struck ball. The tilt angle of the teeing surface is varied about the tilt axis based upon the azimuth difference between the target direction and the actual direction of travel of the struck ball.

Abstract: A device for training a golfer to putt correctly using the concept of muscle memory having an adjustable width, elongated guide path between parallel guide members mounted on an elongated pad. The pad has a fixed guide member and a laterally movable guide member allowing the golfer to form a lengthwise guide path of proper width to allow a putter head of a given width to be swung along the guide path. The device, thus adjusted, guides the golfer in swinging the putter along a straight line and hitting the ball along a desired path. Vertically spaced electrodes running the length of the respective guide member inner walls sound a buzzer when the head of the putter makes contact with the guide member wall. Lengthwise reference lines are provided along the guide path. Crosswise lines are located on the tops of the guide members.

Abstract: The present invention provides a golf practice device having a tiltable golf platform. In one embodiment, the platform is supported by an assembly that allows the platform to be controllably adjusted to simulate various golf lies. The device (200) includes a platform surface (250) mounted in a platform frame (202) that is affixed to a base frame (204) through a pair of actuators (205 and 206), each mounted to the base frame by a pivot block assembly (212) and affixed to the platform frame by an end block assembly (400). The platform frame is pivotally affixed to the base frame by a double cross-joint (203) mounted on the platform frame. The pivot block assemblies allow each actuator to adjust to the side angle relative to the actuator, thus allowing the platform to move freely in two different angles preventing unnecessary stress on the double cross-joint and the positions of attachment of the actuators to the base and platform frames.

Abstract: A practice platform is provided for use by a golfer to practice swinging a club on different inclines. The practice platform has a deck pivotally mounted to a base. Unlike known prior practice golf platforms, the deck is intended to be pivoted to different inclines solely by the golfer's positioning himself upon the deck so that his weight causes the deck to pivot, without the use of a power drive mechanism. The platform includes a mechanism to hold the deck in the selected position, and also to facilitate positioning of the deck by restricting it from pivoting freely through its full range of motion in reaction to the golfer's weight. A valve is provided which can control simultaneously the pivoting of the deck in all directions.

Abstract: A golf swing training apparatus has a flat base for supporting a tee. A target line is marked on the base, through the tee location. To guide the correct swing of a driver, a foam block is positioned on the base on the side of the target line opposite the golfer. The block normally converges towards the target line on the back side of the tee to guide the club head along an inside out trajectory as it approaches the ball. To accommodate the proper backswing, which should follow an inside out trajectory, the guide block is pivotally mounted to pivot about an upright axis to one side of the tee on the base and is resiliently biased to its normal position so that the backswing will swing the guide block out of the way during the backswing.

Abstract: An improved apparatus for golf practice formed from two coaxial wedge-shaped structures, one above the other and rotatable relative to each other and with respect to an underlying supporting platform to provide tilt and tilt direction for practicing golf swings on up slope, down slope and cross slope lies, to simulate the various slope and slope directions of a real golf course. The lower wedge-shaped structure acts as a solid support for the upper wedge-shaped structure and rotation of the upper wedge-shaped structure may result in the tilt of the upper surface of the upper wedge-shaped structures over a continuous range from zero degrees up to the total of the angles of the two wedge-shaped structures. The direction of the tilt angle of the upper surface of the upper wedge-shaped structure relative to an underlying planar base can then be varied by rotating the two structures together about a vertical axis.
