Abstract: A golf training aid helps train a correct golf swing path where for a short period of time, the club is swung straight through the ball and down the target-line for a period of 12 inches, 6 inches before and 6 inches after impact. The golf training aid golfers achieve this flat with all golf clubs. Four six-inch angled polymer poles attach to a base made for driver and wood shots off a tee, and iron and wood-shots off the ground. Feedback is provided when a player hits or misses the poles. Angled poles are fixed to the base's external driver and iron lines for use with the various clubs, and the ball is aligned with one of two center lines, one line being for tee-shots and the other being for shots hit from the ground.

Abstract: A golf swing training aid with a target-line guide, a rail, a clubface guide and an upright assembly. The target-line guide provides a straight line for aiming at a target. The rail runs parallel to the target-line guide and has a bottom for placing on a golfing surface. The clubface guide is perpendicular to the target-line guide and provides a straight line for a clubface of a golf club to parallel with when the golfer sets up or when the clubface passes over, under or through the clubface guide when a golfer swings the golf club. The upright assembly is attached to the rail and is constrained along a straight line on the rail, where the straight line is parallel to the target-line guide and where the upright assembly provides the clubface guide. The target-line and clubface guide can be a rod, a string, a series of laser dots, or a laser line.

Abstract: A golf plane device for use at full golf swing speed and to strike golf balls that trains the golfer to swing the club on the proper golf shaft plane. The device includes a set of bottom 10 and top 8 flexible guides through which the golf shaft 20 travels from thigh high on the downswing to thigh high on the follow through.

Abstract: A golf swing plane training method and apparatus consisting a pair of elastic cords suspended above the ground faithfully defining a cross section of the swing plane. The elastic cords are parallel to each other and approximately parallel to the ground. The plane formed by the two elastic cords is substantially perpendicular to the proper swing plane at a height ranging from the level of the knees to the level of the waist of a golfer at address. The height of the elastic cords is slidably adjustable to accommodate the full range of golf clubs and golfers of varying sizes and heights. The distance between the elastic cords can be altered to accommodate golfers of different skill levels. As the skill level of the golfer improves, the elastic cords can be located closer together. A method for using the apparatus is submitted to provide the golfer with checkpoints that indicate a proper swing plane. In addition, if the golf club is swung incorrectly, the trainer restricts completion of that swing.

Abstract: A putter alignment tool for use in establishing a correct line of putting motion of a golf club head upon a golf ball. An elongated structure includes a first guide wall and a second spaced apart and substantially parallel extending guide wall, the first and second guide walls being secured together proximate at least one of first and second ends. A golf ball placement position is located between the guide walls at an intermediate location between its ends. First and second adjustment mechanisms are associated with at least one of the first and second guide walls.

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: A golf training device for chipping or pitching comprises a vertical support means; an arcuate rigid planar sheet having upper, leading, trailing, and lower edge portions describing an arc of approximately 120°; and an adjusting means engaging said sheet and holding said sheet in a predetermined angular relation with said vertical support means; whereby the golfer may swing the clubhead of a golf club along the inner planar surface of said sheet.

Abstract: A golf swing instructional cage for teaching a quiet lower body swing, employs a minimum of three body constraints: a rear constraint, a forward upper leg lateral constraint and a constraint at the rear of the rearward knee area such that when the golfer is located in the proper initial swing position proximal the rear constraint and knee area restraint and a short laterally spaced distance from the forward upper leg lateral constraint, avoidance of contact with the spaced forward upper leg lateral constraint during the golf swing instructs in quiet lower body control. Optionally a laterally spaced rear upper leg lateral restraint is also provided which, by avoidance of contact during the golf swing further instructs in additional quiet lower body control.
