  • Publication number: 20130324278
    Abstract: The putting practice aid mounts on the front face of the putter head and provides a horizontal arm extending in the opposite direction of the intended initial trajectory of the putted golf ball and a second arm perpendicular to the intended trajectory. When these arms are maintained parallel to the putting surface it assures that the golfer has positioned the shaft at the correct angle relative to the putting surface and that the golfer has correctly aimed the club. The putting practice aid may also comprise an observable coating on the surface of the indicator side of the attachment tab which facilitates establishment of a proper angle between the surface of the face of the putter head and the putting surface. The design of the putting aid allows for use with commercially available putters of varying loft and accommodates handedness preferences. The concepts included in the putting practice aid may be directly incorporated into a putter, which itself then becomes a putting training device.

  • Patent number: 8409026
    Abstract: An improved design for a golf putter has a putter head with a back surface formed in an elliptical shape elongated along a transverse axis normal to a swing plane for the putter, enclosing a hollow interior and having a circumferential rim forming an elliptical frame for the putter head. A head striking surface is formed with a sheet of taut, resilient material secured to the elliptical frame providing a trampoline-like drumhead effect when it makes contact with a golf ball that tends to return the ball's rolling trajectory to the target line of the swing axis even if contact is made off-center. The putter body is an elongated tubular body oriented in the direction of the swing axis, so that the peripheral weight of the putter is aligned along the swing axis and creates a pendulum plumb-bob effect of weight moving under gravity aligned in the swing direction.

The elongated tail section has vertical side walls, into each of which is machined an elliptical track or groove along the inside surface. The elliptical tracks are spaced from each other at a width slightly less than the diameter of a golf ball, and are machined into the sidewalls at a predetermined angle of incidence such that, when viewed from directly overhead, the tracks will be perceived by the user as two parallel lines. If the user's eyes are not directly in line with the plane extending vertically from the centerline, then one of the tracks will increasingly disappear behind its respective sidewall, while the opposite track will appear to become increasingly curved, as the degree of misalignment increases. The putter thus provides a means of alignment that improves putting accuracy.

At the sides of the tail there are formed end fins with their free ends opened rearward to better guide the putter head through the air during the stroking address. The top of the back weight extends to near midway of the length of the tail and merges with the bottom of the tail. The back weight has a bottom surface in flush with the corresponding bottom of the main body and terminates with an end wall tapered gradually toward the main body to avoid hitting the ground when strokes are made. Three cylindrical bores are formed facing the same backward direction in the common 90-degree angle from the rear wall to receive different metal screws.

  • Publication number: 20030228925
    Abstract: A golf putter in which most of the clubhead mass is distributed at three or more prescribed locations within a “Mass Ring” approximately equidistant from, and as remote as possible from, the clubhead planar center of mass with the clubshaft axis preferably forward of the clubhead center of mass thus maximizing both putter and clubhead planar moment of inertia for improved putter performance during mis-hits. Maximum remote mass is achieved by interconnecting the remote high mass areas (Mass Ring) with the putterface striking area and the putter shaft connection point with a light weight rigid open (see thru) truss system so arranged to enhance the Sighting Field and/or sight or aim line on the putterhead while preventing undesirable vibration of individual clubhead members. Such Sighting Field and Sight Line can be further enhanced via use of one of several light weight replaceable and angular adjustable Sighting Fields and/or Sight Lines preferable to an individual golfer.

  • Patent number: 6045453
    Abstract: The new golf putter/chipper clubhead of this invention, which is generally hammer shaped both in plan view and in cross section, provides for an easily accomplished true pendulum swing by concentrating the mass of the club at the very perimeter of the arc of the pendulum, on-line with the direction of swing. The concentration of clubhead mass, being very low and directly behind the ball striking area of the clubhead makes it much easier to get very solid ball contact. A single club using this clubhead design can be used either right or left handed, even though there is but one ball striking face. The unique design enables contrasts in color, and/or texture, and/or reflective angle to be used to graphically alien the clubhead before and during the stroke. By optimizing the clubhead weight, as described in this invention, regulating the length of chips and/or putts essentially becomes an exercise in simply regulating the length of the backswing.
