Dual radius putter
First Claim
1. A putter for putting a golf ball comprising:
- a shaft with a handle end and a mounting end;
a handle secured to said handle end; and
, a putter head fixably mounted to said mounting end having a front surface for engaging a golf ball, a rear surface, and a bottom surface, said front surface having a substantially convex shape defined by an upper radius and a lower radius, said upper radius being smaller than said lower radius, said upper and lower radii meeting longitudinally along a linear path on said putter head, said rear surface having toe, mid-toe, center, mid-heel, and heel portions, said toe, center, and heel portions protruding outwardly beyond said mid-toe and mid-heel portions, wherein said mid-toe and mid-heel portions are filled with weighted material having a greater density than that of said putter head.

Abstract
Several embodiments of a golf club putter having a novel putter head with a striking face defined by two unequal radii are disclosed. In one embodiment, the convex striking face is defined by an upper radius and a lower radius meeting along a linear path to provide an single point of contact for the engagement of a golf ball. In a second embodiment, the upper radius and lower radius meet along an arcuate path, and a protruding bottom surface mimics this arcuate path, to provide an optimum point of contact for a golf ball regardless of the longitudinal angle of address of the putter. Dual radius putters having weighting schemes and composite or plastic inserts are also disclosed to further improve the true roll of a golf ball generated by an engagement with the instant putter.

14. A putter for putting a golf ball comprising:
-
a shaft with a mounting end and a handle end, a handle secured to said handle end, and a putter head fixably attached to said mounting end, said putter head having a front face for engaging a golf ball, a front portion longitudinally opposed to a rear portion, and a bottom surface, said front face defined by a first radius of curvature and a second radius of curvature, said first and second radii of curvature being unequal and meeting longitudinally along an arcuate path defined by a path radius on said putter head and in a substantially smooth manner so as to produce a continuous but nonuniform convex front face, said bottom surface having a convex shape defined by a bottom radius, said bottom radius being complementary to said path radius, and said putter head having weights fixably disposed in said front and rear portions. - View Dependent Claims (15)
