Abstract: Disclosed is putting stroke training device that consists of a flat base with an adjustable width channel running its length. The user adjusts the channel to a size slightly wider than that of his/her putter's head so that it will pass freely there through with a slight clearance. A ball holder located in the middle of the channel holds a golf ball in a position such that it can be struck by stroking the putter through the channel. A series of distance indicating lines along the interior of the channel allow the user to gauge the strength of the stroke, allowing them to develop a consistent stroke, while the channel ensures a straight, level stroke.

Abstract: A device that provides feedback to a golfer on the characteristics of their swing of a golf club. The device can be mounted to or incorporated into the head of the golf club and includes a first light source and at least a second light source. The first and second light sources are aligned such that an imaginary line bisecting the first and second light sources passes through the sweet spot of the ball-striking face. When the club head is at the address position, the imaginary line lies in a horizontal plane and is further preferably at right angles to the ball-striking face in that plane. The first and second light sources are visible to the golfer when using the golf club at least at the time when the club head is striking the ball. The first light source has a first turn on/turn off cycle pattern and the second light source has a second turn on/turn off cycle pattern that is different to that of the first light source.

Abstract: A golf swing aid constrains the swing of an associated headless golf club to provide a golf student with proper golf club swing notion. Flanged backswing and downswing rails are intermediated by a continuous curved rail and supported by a rail support. The curved shape of the rails is derived from the proper "inside out" professional-type golf swing and may be determined on a theoretical or experimental basis. A headless golf club has a rolling clevis that engages the flanged rails to roll thereupon. The golf student so engaging the headless golf club is then constrained in the golf swing to follow the shape of the rails. This requires the student to use the back muscles rather than the wrists, arms and shoulders to develop the proper swing action. The flanged rails have open ends so that when the point of impact is reached at the completion of the downswing, the student may follow through on the shot with the headless golf club leaving the downswing rail.

Abstract: A device and method for improving the putting of a golf ball is described herein. The instructional device employs a sighting member and a shaft guide to assist in aligning and stroking a golf putt. The device is configured such that a golfer or instructor may develop each putting skill independently or in combination with the other skills. The device comprises two stands, set apart, with the sighting member attached to the top of each stand. A square face indicator may be positioned perpendicular to the sighting member, and the shaft guide may couple to a side of the stands. A method for improving the putting of a golf ball is also described herein, where the method addresses finding and verifying a sight line that extends from a golf ball to a desired target, aligning a golf putter face squarely to said sight line, and moving a putter shaft parallel to said sight line.

Abstract: A golf training device features a support base with a light source attached thereto, the light source generating a planar-shaped beam of light which is projected forward of the support board to form a target line on the ground. The target line can be used in alignment of the golfer's body and club face before and during the striking of the golf ball. A pair of removably attachable elongated guide rails can be attached to the top of the support base to provide a guide path for the golfer to move the club head therethrough while putting a golf ball from the top of the support base. The positions of the guide rails can be selected to accommodate putters having different club head lengths, as well as to provide for lesser-constrained guide paths. The light source includes a laser and a cylindrically-shaped optical element placed transversely to the light beam to create the planar-shaped beam.
