Abstract:
A putter head having an elastomeric core that provides resonant feedback having an amplitude corresponding to applied force, comprising:a peripherally weighted body having a uniform first density, said body having a full depth cavity extending along a first axis from a planar front face of said body to a rear face of said body so as to expose opposite ends of said cavity on, respectively, said front and rear faces of said body, said cavity and said first axis perpendicular to said front face of said body,an elastomeric core mounted within said cavity so as to completely fill said cavity, said core mounted solely by frictional adhesive engagement between an outer perimeter surface of said core and a surface of said cavity, said core having a uniform second density, said core having opposite front and rear faces, said front face of said core coplanar with said front face of said body,wherein said outer perimeter surface of said core and said surface of said cavity are free from asymmetric irregularities,wherein said second density is substantially less than said first density,wherein said core is, in cross section perpendicular to said first axis, symmetric about orthogonal second and third axes lying in said cross section, andwherein said core dampens sound vibration commensurate with an applied force resulting from direct impact of said front face of said core with a golf ball, and redirects said force radially, orthogonal to said first axis, into said peripherally weighted body for transmission of said force by said body as tactile and audible feedback to a user, said feedback having an amplitude corresponding to a magnitude of said transmitted force,wherein said feedback produced by said body after a golf ball impacts said front face of said core indicates the force of the impact independently of the hardness of the composition of the golf ball.
