Abstract: A golf club head, and particularly a putter head, comprising at least one visual reference point that shows a golfer the ideal vertical impact height at address and at impact is disclosed herein. The visual reference preferably is an alignment aid, such as an alignment pin or bar, which delineates the vertical center of the face between the top and bottom portions of the golf club head along the vertical z axis.

Abstract: A golf club head comprising a crown with an edge support structure and a flexible, conformal weight sized to fit within the edge support structure is disclosed herein. The edge support structure preferably is disposed on an internal surface of the crown so that the conformal weight is invisible when the golf club head is viewed at address. The conformal weight can be removed to adjust the vertical center of gravity of the club head, and preferably is oriented in a front-to-back direction along the club head's X-axis. The conformal weight preferably is composed of a high-density polymeric material with a specific gravity ranging from 1.8 to 4.2.

Abstract: A putter club head is provided with an elongate cavity communicating to the exterior through a rectangular opening in the striking face thereof spaced above the club head lower surface so that the portion of the club head between the cavity opening and the lower surface forms a lower shielding structure to deflect any plant growth in the path of a putting stroke. A conforming cylindrical roller is then mounted for rotation within the cavity to provide a ball striking surface on its periphery generally elevated above the bottom surface to a height corresponding to the elevation of the contact periphery of a golf ball resting thereon. In this manner little or no spin is imparted to the ball when struck by the roller since the lower club surface shields the roller from any moments imparted by the growth covering the green.

Abstract: A putter club head is provided with an elongate cavity communicating to the exterior through a rectangular opening in the striking face thereof spaced above the club head lower surface that forms a lower shielding structure to deflect any growth in the course of a putting stroke. A conforming tubular segment is then mounted for rotation within the cavity to expose a portion of its peripheral surface beyond the plane of the striking face generally elevated above the bottom surface to a height corresponding to the elevation of the contact periphery of a golf ball resting thereon. In this manner little or no spin is imparted to the ball when struck by the roller since the lower club surface shields the roller from any moments imparted by the growth covering the green.

Abstract: A golf training device that is equally useful in developing a putting stroke and a swing stroke. A club head is severed in the middle and a ball is rotatably secured between the head segments. A circumferential line is applied at the ball's equator defining a plane perpendicular to a line about which the ball rotates. Rotation of the ball is employed for training certain strokes or segments of strokes, and the circumferential line is employed for training certain strokes or segments of strokes.

Abstract: The wheeled putter is a putter using a shrink fit process to secure the putter head to wheels in order to provide a training putter that ensures a uniform putting height above ground. The wheeled putter includes a putting head and a pair of wheels mounted onto the putting head. The wheels each have a bearing assembly mounted in the wheel hubs. The putter head is cooled, thus shrinking the putter head, which is then pressed into the bearing assembly. When returned to room temperature, the putter head is secured directly against the bearing assemblies of the wheel by expansion of the axle shaft against the bearing assembly.

Abstract: A golf swing training device comprises a free-spinning wheel or roller assembly mounted permanently or secured detachably to a golf club of virtually any design, which accelerates learning by conceptually substituting a simple, cohesive, and intuitive action for the complex and seemingly disjointed motions of the golf swing. The position and alignment of the wheel assembly provides inherent and easily discernible visual references with respect to the desired aim and lie angle of the golf club. The user, after adopting an orthodox setup, will be encouraged to roll the wheel back with both arms, and then vigorously and forcibly bring the club and wheel assembly forward toward the intended target to induce momentary, tangential contact with the surface of the ground, causing the wheel to rotate freely—a direct indication of the quality, timing, and speed of the release of the hands.

Abstract: A practice putter for improving a golfer's putting game having a conventional grip attached to a conventional shaft. The shaft is connected to a head having a concave bottom surface of a predetermined radius. One or more balls are mounted in the bottom surface on an axle, and each ball revolves freely only in the direction of the axle. Each ball is positioned adjacent opposed sides of the concave middle portion. Each ball is mounted on an axle having a shock system that allows the ball to be pushed inward towards the head with the application of a predetermined force thereon. The length of the shaft is adjustable, and the angle determined by the top surface of the head and the shaft is also adjustable. In proper use, each ball is made to contact the putting surface as the head is moved in a straight line guided by the rolling balls.

Abstract: A golf swing training club that trains a golfer to square more accurately the golf club face during the swing for improving the golfer's swing and golf game. The golf swing training club generally comprises a shaft, a cylinder or clicker, and a roller ball to practice precise contact. The hinged club head is adapted to make a clicking noise when it breaks down to indicate an improper swing tempo. The roller ball spins when the club face is squared at the time of impact. Swing practice with the training club of the present invention trains a golfer to develop a slower, more fluid, motion swing to thus achieve and maintain a truer swing plane for consistently making contact with a golf ball when playing golf. The spinning roller ball also allows a golfer to practice keeping his head down and his eyes on the target point. The training club of the present invention can be used by both right handed and left handed golfers.

The swing training machine is used for practicing swing motion of golf, throw events, racket sports etc. easily and safely and to strengthening and increasing the flexibility of muscles of arms, shoulders, the body and legs involved in the actual motion of each event.

Abstract: The invention is directed to a roller putter secured to a golf club shaft. The hitting surface is a cylinder, rotatably mounted on two roller bearings, fastened to a bottom portion of a hosel, and the cylinder has two "O" rings mounted in two grooves formed around the periphery of the cylinder, the "O" rings defining a "sweet spot" area for hitting the golf ball and two lines for sighting the roller head with the desired path of the struck golf ball.

Abstract: A golf stroke instruction device comprising an elongate, pivotally mounted club-engaging component whose range of motion can be selectively controlled by the user. This novel club-engaging component is operatively mounted adjacent at least one generally vertically disposed planar member. The planar member has an upper portion upon which the component is pivotally mounted for free swinging motion, with the planar member also having a face portion as well as a pair of side portions. A motion-limiting arrangement is utilized on each side portion of the planar member, serving to limit the motion of the club-engaging component as it moves along the face portion of the planar member and approaches a side portion.

Abstract: This invention provides golf putter training tools for training a golfer's putting stroke. These golf putter training tools assist a golfer in making the putting stroke flat and in a straight "sweeping" line. A wheel, attached to the putter body, is provided adjacent each end of the putter and constructed to roll when the proper putting motion is used. The wheels (provided either as a putter part or as an add-on) extend slightly below the bottom surface of the putter and may include sharp portions along their circumference to impede other than straight rolling.

Abstract: A golf putter training device that includes a clip for removeably attaching a bracket having a roller mounted therein. The clip includes at least one finger to hold the bracket in place during a practice putt, and allows the bracket to be easily removed for the final putt. The bracket may include resilient washers located between the bracket arms and the ends of the roller, and the roller may include a polymer coating on each end. A misaligned putting stroke will result in a coated end of the roller being forced against one of the washers, thereby generating friction and providing directional feedback to the user.

Abstract: A golf club has a clubhead upon which is rotatably mounted a rotary member or roller. The roller is exposed at the front of the club to engage the golf ball and is free to rotate upon a horizontal axis while in contact with the golf ball to facilitate rotation of the golf ball as the club moves the golf ball across the ground. The clubhead preferably has a front face that is directed toward the ball and the roller is mounted on the clubhead as a part of the front face of the club so as to engage the ball and to rotate freely while in contact with the ball. Typically, the clubhead has a pair of horizontally spaced apart supporting walls with an opening between them to accommodate the roller and to support the roller for rotation about a horizontal axis with the roller located at an elevation adapted to engage the center of the ball but to be held out of contact with the ground.

Abstract: A golf putter training device that includes a removeably attachable bracket and a roller mounted in the bracket. In one embodiment, the invention features a golf putter comprising a bracket removeably attachable to the bottom surface of a putter and a roller mounted in the bracket. The bracket of the training device is held onto the bottom face of the club head by mounting pins that fit into outwardly facing holes in the bottom surface of the putter. The bracket that holds the roller may be fabricated of a flexible material, such as spring steel or plastic. The roller is approximately 70% the length of the club head to provide friction to alert the user to a misaligned putting stroke.

Abstract: A rolling head putter that comprises a standard design putter head in conjunction with an axle and rotatable roller. The axle supports the roller and provides for free rotation of the roller in a direction orthogonal to the direction of the line of sight in the direction of the putt. The roller is mounted behind the leading edge of the putter and may have a resilient outer surface, and extends below the lower surface of the putter head such that the putter head rests on and glides across the ground surface on the roller. In a preferred embodiment, the axle and roller are contained within and bounded by a cavity that penetrates the putter head, such that the overall perimeter of the putter head is of similar size and shape to generally available standard putter heads.
