Abstract: The chalk-dispensing golf training club is a simulated golf club head that is mounted on a golf club shaft. The chalk-dispensing golf training club is not intended to be used with a golf ball. During training sessions, the chalk-dispensing golf training club is swung as a normal golf club. As the chalk-dispensing golf training club hits the ground, the chalk-dispensing golf training club leaves a chalk mark on the ground which indicates the plane of the swing. Through analysis of the chalk mark, an assessment can be as to whether the swing would result in a straight shot, a draw shot or a slicing shot. This information can be used to adjust the trainee's foot placement and to practice swings with the adjusted foot placement. The chalk dispensing golf training club comprises a practice head, chalk, a shaft, a grip.

Abstract: An integrated golf club and analysis system that measures and analyze the performance characteristics of both: 1) a free golf swing without impact with a golf ball and 2) a golf swing with ball impact analysis. Free swing analysis provides critical information needed to analyze swing style so that dynamics swing characteristics optimization can be evaluated throughout the entire swing without ball impact, while impact analysis provides critical information on ball impact location on the club face, however, they cannot be measured simultaneously since ball impact eliminates the ability to identify the swing metric peaks such as velocity if it were to occur after ball impact. To achieve both, an integrated electronics golf club head comprises multiple types of sensors for measuring club head motion, impact and spatial location information with a weight and balance of a regulation golf club head.

Abstract: A golf practice and exercise device has an elevated arm from which an impact object is suspended for swinging movement. The object is positioned with a clubhead impact target in position for striking by the clubhead of a golf club swung by a golfer. The resistance to the impact of the golf club is adjustable. A sensor detects the magnitude and velocity of the striking force, and a display displays an indication as to how far a golf ball would have gone after being struck with a force and velocity of the detected magnitude.

Abstract: A golf swing practice apparatus is provided including a rotating drum, a plurality of laser generating means mounted on the rotating drum, an elongated cord including a proximal end secured to the rotating drum and a distal end secured to a golf ball whereby the golf ball is tethered to the rotating drum, a base member having an impact area over which a user may swing a golf club, and a frame structure secured to the base member and to the rotating drum whereby the frame structure holds the rotating drum in an elevated position above the base member. The rotating drum rotates with the golf ball when the golf ball is struck by the user. At least one of the plurality of laser generating means generates a laser beam which propagates substantially along the path of the golf ball. Additionally, at least one of the plurality of laser generating means generates a laser beam which propagates parallel to a theoretical path of a fairway.

Abstract: An apparatus for developing and practicing golf skills that is readily portable and which can be used in a relatively restricted or confined areas is provided. The apparatus includes a shot indicator mounted on a vertical shaft which is caused to rise on the vertical shaft during use as indicator of the effectiveness of the shot in terms of distance of flight which would have been attained by a golf ball if driven by a blow of equal force and direction. The shot indicator is caused to rise on the vertical shaft by a user hitting a target which is laterally spaced from the vertical shaft. A target support is rotatably attached to the vertical shaft at one end and supports the target at an opposite end. Rotation of the target support releases a compression spring which acts on the shot indicator causing it to rise on the vertical shaft.

Abstract: An apparatus to be used to practice golf shots in limited space. A golf ball is tethered to one end of a line and the other end of the line is secured to a support which is calibrated to indicate the distance the ball would have traveled, when struck by a golf club, if the line were not secured to the support. The system includes an energy absorption device to control and limit the movement of the line through the system as the ball is struck.

Abstract: This invention relates to a golf practice aid which allows the golfer to estimate the distance and direction of a struck ball, while using a limited space, not compromising the feel and rotation of the ball and allowing for the golf ball to come to rest near its original striking position. In the preferred embodiment of the invention, a mass freely rests upon a flat surface. A horizontal bar is inserted and secured through a hole through the mass, extending equidistantly from the center of gravity of the mass. A cord is secured to spaced-apart points on the bar, preferably at opposite ends of the bar. A golf ball is secured to the cord, by virtue of the cord passing through a hole through the center of the golf ball, with keepers to prevent the golf ball from sliding any significant distance along the cord. The hole through the golf ball preferably is large enough to allow the ball to spin on its axis around the cord when struck.

Abstract: A golf practice device has an angled, curved or straight frame made of tubular steel on which two anchor points are formed between which a rope is tensioned. A golf-ball-like body is tracked along the rope by means of a flexible connector. A strike plate is located on the rope in the vicinity of an upper anchor point. The frame and the rope form a closed tensioning system which generates vibrations in the rope when the body hits the strike plate, where the magnitude and direction of the amplitudes of said vibrations are a function of the point of contact between the body and the strike plate. The vibrations of the rope affect the type of movement of the struck body during its return to the first anchor point such that the user can draw conclusions about the nature of his golf swing.
