Abstract: A roller assembly for smoothing an expanse of granular media such as golf bunker sand, snow, horse race track dirt, or other media. The assembly has one or more rollers having a longitudinal axis. Each roller includes wires spaced from the axis to define a roller surface. Each wire is resiliently flexible to distort inwardly in response to force of contact on, and to recover during release of force from, the granular media as the roller rotates about the axis on the granular media. A shaft extends along the axis of the roller assembly between the arms of a yoke with a handle extending therefrom. As the roller surface traverses the media, at least some of the media is flung outwardly of the roller, smoothing the expanse. The roller assembly may be manually operated or may be towed behind a towing apparatus.

Abstract: A grip for a shaft for a golf club, the golf club comprising a head provided at a first end of the shaft and a second end of the shaft corresponding to the hand placement area on which the grip is formed, and a method for forming such a grip are disclosed. A grip comprises a sleeve of heat-shrinkable material adapted to be inserted over the second end and an under listing positioned along the second end, wherein the sleeve is inserted over the second end and the under listing positioned thereon, and shrinks onto the second end upon heat application. A method for forming a grip comprises positioning an under listing along the second end, inserting a sleeve of heat-shrinkable material over the second end and the under listing positioned thereon, applying heat to the sleeve such that the sleeve shrinks onto the second end.

Abstract: An athletic swing trainer permits an athlete to swing a trainer at speeds far in excess of the athlete's conventional swing speeds and to confirm to the athlete that the practice swings made with the trainer at these extremely high speeds have been technically properly executed. Armed with this experience, the athlete is then able to swing the athlete's own conventional club, bat or racquet at speeds which, though lower than the athlete's trainer swing speeds, are significantly higher than the athlete's conventional club swing speeds. After six or seven trainer swings, an athlete's swing speed at point of contact of a conventional golf club, bat or racquet with a corresponding ball is typically increased in a range of 5 to 15%.

Abstract: A tennis serve trainer mechanically encourages and causes the execution of a counter-intuitive hitting-up-on-the-ball service swing. The trainer has a straight shaft and a ball which can slide freely on the shaft between a tennis racquet grip on one end and a cap on the other. The ball is magnetically held against the grip until a threshold swing speed releases the ball. The magnetic force, the distance from the grip to the cap and the weight of the ball are coordinated so that the ball will strike the cap at the apex of the swing. At that moment, the arm is fully extended, the racquet head speed is accelerated to its maximum, the angle of attack is ideal, the ball and the racquet meet at the perfect impact point at the apex of the serve, and a snap in the racquet motion happens automatically at the top of the swing.

Abstract: A golf stroke training device includes a base that has a first section and a second section, and a vertical guide coupled to the base. The vertical guide is substantially perpendicular to the base. The first section has an arc extending from an approximate midpoint of the device to a first end of the device, and the second section comprises a substantially straight edge extending from the approximate midpoint of the device to a second end of the device. In another embodiment, the second section comprises a substantially straight edge extending from the approximate midpoint towards the target and an inside along an arc.

Abstract: A golf training device includes a template. The template has a passageway in it to receive a golf ball, and at least one hole on each side of the template to receive a golf tee or similar structure. The golf tee on each side of the passageway creates a boundary through which a putter can pass and strike the golf ball in the passageway.

Abstract: A putter club head has a longitudinal body and a means of attaching a shaft thereto. The body may be solid, hollow, or partially hollow or solid. If hollow or partially hollow, the body may have a weighted mass therein. Such a weighted mass may be located towards a front section of the club head near a ball striking surface. The means to attach a shaft is located in the rear section of said body in proximity to the distal end of the rear section of said body. The shaft may curve and bend so that it is oriented near the center of the body and towards a golfer addressing a golf ball.

Abstract: In an embodiment, a golf club driver includes a club head and a shaft attached to the club head. In a particular embodiment, the ratio of the weight of the club head to the weight of the shaft is within the range of approximately 1.2 to approximately 1.6.

Abstract: A golf swing strength trainer has a shaft of length not greater than that of a standard golf club shaft. A golf grip is fixed to one end of the shaft. A golf club head is fixed to the other end of the shaft. A pair of substantially equal weights is fixed concentrically on the shaft, one on each end of the grip, the center of gravity of the weights taken together being located substantially at a lengthwise center of the grip. Preferably, the weights abut the opposite ends of the grip. In use, as the axis of the shaft comes into horizontal and vertical alignment, the horizontal distance of the weights from the center of gravity is maximized and minimized. This relationship seems to trigger rather than inhibit the transitional phases of the swing. Since the weights, regardless of their anglular position, are equally displaced from the center of the grip, they tend to enhance rather than inhibit flow and transition of primary movers in the proper swing plane.

Abstract: A golf swing trainer employs a solid steel shaft homogeneously weighted throughout its entire length. One end of the shaft is fitted with a standard golf club grip and the other end of the shaft is fitted with a rubber tip to afford some protection for walls, floors and furnishings should the golfer elect to use the device indoors. A golf club head can be used instead of this tip for visual or psychological reasons. The top of the shaft bears a straight line indicia as a club face reference. The homogeneously weighted shaft so closely positions the center of gravity of the training device to the center of gravity of an actual golf club on a correct swing path as to break down incorrect muscle memory and simultaneously develop the muscle memory appropriate to the correct golf swing.
