Putter Head

Abstract

The putter head is symmetrical in form, mirrored toe and heel as determined by a center line extending the full length of the putter as shown in the top view. The Putter head has forward weighting achieved by plotting the center of gravity (COG) of the head as a point and assigning three axis lines. A fourth axis, the longitudinal axis of the shaft extending from the grip and remaining straight is then positioned to intersect with the z-axis of the COG as defined in full description by way of a shaft hole which is determined in the design stage. The COG lies between the face and the intersection of said z-axis by the shaft axis. The elevated rear section helps to raise the overall COG to a height at or above the center of a golf ball during the putting stroke. This results in a putter head whose face is predominately parallel with and facing the ground surface when balanced on it's shaft horizontally suspended so that the putter head can rotate freely. The putter head has the additional features of a double rocker, heel to toe and face to rear, and ball pick up flanges at the rear.

1 . The putter head consists of a planer face substantially perpendicular to the ground plane for striking the ball, a heel area which is closest to the golfer, a toe area which is furthest from the golfer and is symmetrically mirrored along the center line from the heel and a rear area furthest from the face, a top surface fully visible to the golfer and a bottom surface which is not visible to the golfer at address;
 there is a center of gravity (COG) and a diagonal hole for the shaft, the longitudinal axis of which is angled between 68 degrees and 76 degrees as measured from the ground plane and intersects the z-axis of the COG at a point that is at least 2 mm and at most 20 mm further from the face than the COG, thereby creating a face down, predominantly parallel to the ground balance when the shaft is held horizontal to the ground, additionally there are two symmetrical protrusions extended from main body to the rear of the club head, further from the face than the shaft hole that are tapered and open between the two, and whose outer edges follow the outline established by the outer extents of the heel and toe while the bottom of the club head is angled upwards between 15 degrees and 22 degrees as measured from the ground plane, starting from a point approximately where y-axis of the COG intersects with the bottom of the club head and continuing toward the rear termination of the club head, raising the overall COG of the club head so that during a putting stroke the COG is at a height equal to or higher than the center of a golf ball.   
     
     
         2 . The putter head as in  claim 1 , has curved rocker lines along the bottom surface on both the face, visible in front view and front to rear visible in the side view, the two rockers curves having separate function and combined functions; the convex bottom rocker curve in the front view is based on an arc whose center is directly above the center line having a radius of more than 200 mm and less than 280 mm that facilitates different shaft angles employed by a golfer, relative to the ground plane while setting up for a putting stroke without creating a higher incidence of ground contact and a
 front to rear rocker curve or bend that begins at the approximate intersection of the y-axis of the COG which if extended would contact the bottom surface of the putter head transitioning the remainder of the bottom in a fairly straight fashion, rising at an angle of between 15 degrees and 22 degrees in relation to the ground plane until terminating at the rear.
