Abstract: A golf putting apparatus is presented. The apparatus includes a putter with a shaft and a club head, wherein the club head has a center section carved out to form an opening. The bottom of the opening may be defined by a connector. When used with the opening uncovered, this putter provides the golfer with immediate feedback on his/her swing, such as whether the ball would have contacted the sweet spot of the club had the opening been closed, how hard the ball was hit, and which part of the ball was hit. A club face may be attached across the opening to “close” the opening so the putter may be used in a game.

Abstract: A swing training system includes a base unit having a grapple that is movable between open and closed positions. A free end of an elongated swing device, such as a golf club or a hockey stick, is secured within the grapple. The swing device is manipulated to exert a force on the grapple and a load cell, away from the base unit, for a predetermined value, such as force and/or time. Relative movement between the grapple and the base is substantially limited while the swing device is manipulated. Once the predetermined value is attained, the grapple releases the free end of the swing device.

Abstract: A golf practicing device includes a golf ball and a ball anchoring assembly which includes a restraining cord and an elastic cord. The restraining cord, which is made of non-elastic material, has an affixing end affixed to the golf ball and an anchoring end. A maximum traveling distance of the golf ball is restrained by a maximum length of the restraining cord between the affixing end and the anchoring end. The elastic cord is provided along the restraining cord that shortens a distance between the golf ball and the anchoring end of the restraining cord. When the golf ball is hit to fly at the maximum traveling distance, the elastic cord absorbs a tension of the restraining cord and pulls the golf ball back toward its spot position.

Abstract: One embodiment of a golf practice device comprising an upright support (12); a shaft (38) affixed to the upright support in a substantial horizontal orientation in predetermined height above a ground; a ball body (16) rotatably mounted to an outer end of the shaft; and a stopping member (14) attached to the upright support in a substantial horizontal orientation in position above the shaft. When a gold ball is struck by a golf club, it rotates about a horizontal axis and is stopped by the stopping member. The ball body is further slowed down by the unraveled cord (56) scratching the floor. After being hit with the full speed swing, the golf ball comes back into its initial quiet position in less than 5 seconds. Other embodiments are described.

Abstract: A golf swing trainer system includes a frame formed by one or more frame elements, and a training ball that simulates or is formed from a golf ball.

Abstract: A golf practice and exercise device having a frame with a horizontally projecting arm spaced from a base or from the ground and from which is suspended by a cord an object that may take various forms, such as similar to a standard softball, a teardrop-shaped punching bag, a body punching bag, or any other suitable form. The object is positioned with a clubhead impact surface in position for striking by the clubhead of a golf club being swung by a golfer. The impact surface is sufficiently large that a golfer need not concentrate on striking a small target as is required when swinging at a golf ball. The mass of the object is sufficient to provide substantial resistance to the impact of a golf club to impose muscle strain on the golfer for muscle development, but is limited in mass to allow the head of the golf club to swing the object sufficiently for the golf clubhead to ultimately pass under the object and allow the golfer to complete the follow-through of the golf swing.

Abstract: A golf swing training device is provided herein. A ball is connected to a line wound about a reel, and one or more weights are slidably positioned upon the line. When the ball is struck, its inertia strips line from the reel, and the line trails behind the ball in flight. Simultaneously, the weights are carried along by the line, and these weights exert a downward force on the line, thereby dampening the flight of the struck bail and forcing the ball back toward the ground. Also, when the ball's trajectory curves upward, the friction between the weight and the line increases, thus decelerating the ball. After the ball strikes the ground, the ball can be retrieved by manually rotating the reel in the preferred embodiment.

In use, the weighted bag weighs the golf practice device down, the elastic cord functions to return the ball, and the swivel element permits relative rotation of the elastic and non-elastic cords.

Abstract: Golf practice apparatus utilizing a tethered golf ball wherein the kinetic energy is dissipated when the ball is struck. Initial velocity vectors in the x, y, and z coordinates are derived by time integrating the respective forces over the period of time during which the kinetic energy is dissipated. From these derived velocity vectors is computed what the trajectory of the golf ball would have been if it had been untethered. Alternatively, two of the initial velocity vectors may be derived as described above and the third obtained mathematically after first deriving total initial velocity. Golf ball spin about a vertical axis may be obtained for correction to the trajectory by means of a reflective strip on the ground facing surface of the golf club head and two or more sensors for detecting the reflections from opposite ends of the strip.
