  • Publication number: 20100255928
    Abstract: A putter club is provided which enables accurate putting by maintaining an angle of a ball-hitting surface with respect to the horizontal plane during a swing. When a player holds a grip with both hands and back-swings from an address position, a shaft is inclined toward a positive side of an X-axis. In this process, the head is pivoted by its own weight around a rotational axis which is horizontal, which is parallel to the ball-hitting surface, and which passes through a center of mass of the head, and an angle of the ball-hitting surface with respect to the horizontal plane is maintained. In the process from start of the swing through an impact to a follow-through, the shaft is inclined toward a negative side of the X-axis. During this process also, the head is pivoted by its own weight around the rotational axis, and the angle of the ball-hitting surface with respect to the horizontal plane is maintained.

    Abstract: A golf putter providing a center mount of the hosel to the club head and a shaft engagement to the hosel at the heel end of the club head. The center mount provides the sole engagement of the hosel to the head as a gap is formed by a pathway formed through the body of the head which is larger than the circumference of the hosel in its communication therethrough. The centered engagement provides better touch to the user and feedback on striking a ball while concurrently removing the shaft from the user's line of sight to the ball and club face and reduces the twist or torque at impact with a golf ball, thereby increasing the moment of inertia.

  • Publication number: 20090054174
    Abstract: The current invention is a golf putter designed to be held by only one hand in order to achieve the ability to produce a pure pendulum motion. The pure pendulum motion has many advantages and solves problems encountered with the conventional two hand putting method. The shaft diameter is large enough to be gripped comfortably by one hand, anywhere along the shaft, and held against the arm, so that the arm and putter move in unison as a pendulum whose pivot point is the joint of the golfer's upper arm and shoulder. The golfer can move the putter in a coplanar motion similarly to a pure pendulum. The striking face of the putter may be set and maintained perpendicular to the target line, thereby solving the variable face angle problem attendant putting with two arms. Other putting errors are eliminated. The putter also works with two hands.

  • Patent number: 7175537
    Abstract: A putter has a center of gravity located rearward from the face and under the stroking pivot point. The polar moment of inertia of the putter is increased by moving the distribution of weight toward the rear of the head away from the contact surface. The sole of the putter has an optimized transverse radius and a raised front edge. The putter has an aiming mark that has a minimum area and a minimum length-to-width ratio and is brightly colored. The putter grip has a flat portion that is oriented to match the player's hand rotational position. The face of the putter has friction and energy transfer characteristics that are selected to influence ball motion if struck with stroking errors. The face loft angle cooperates with the face surface characteristics to influence ball launch angle and rotation.

  • Patent number: 7169058
    Abstract: The present invention provides a golf putter head that is suitable for putting a golf ball by either left-handed or right-handed golfers by swinging the putter in the typical pendulum motion or by pushing the putter in a shuffleboard-like motion. Further, the present invention provides a golfer with the ability to select the angle of the golf putter shaft to the golf putter head. The golf putter head comprises a top, a bottom, at least one flat striking surface, at least one curvilinear striking surface and a shaft receiving aperture. The top contains an insert having a variety of shaft receiving apertures. The shaft receiving apertures are of different angles to allow a golfer to pick the desired angle to better fit his or her needs. Further, the radii of the curvilinear striking surfaces are of such dimensions that the curvilinear striking surface, when used in the shuffleboard-like motion, strikes a golf ball above the golf ball's horizontal midline, which encourages topspin.

  • Patent number: 7163463
    Abstract: A golf club is provided in which a front heel face of the club defines a bore for receiving one end of a hosel, the hosel defining a substantially right angled bend. A free end of the hosel engages the putter shaft. The hosel provides a desired offset distance from the club strike face. Rotation of the hosel relative to the bore also provides an adjustment mechanism by which the lie angle and face balancing of the club may be achieved. Shaft inserts are also provided to adjust lie angles and offset distances.
