Abstract

Abstract A molding apparatus for manufacturing a molded golf club grip includes a mold member having a generally cylindrical shaped cavity disposed therein and defined by an internal annular surface. The cavity has a longitudinal axis and a circular cross sectional configuration. An elongate core bar is disposable within the cavity with the longitudinal axis of the cavity and the core bar being coextensive. The core bar has an external surface which is spaced apart from the internal annular surface of the mold member when the core bar is disposed in the cavity and the annular surface of the mold member cooperates with the external surface of the core bar to define a molding cavity for receiving a moldable material therein for molding a golf club grip. The external surface of the core bar includes first and second substantially planer portions disposed substantially parallel to each other, a third planer portion disposed substantially perpendicular to the first and second portions and an arcuate portion interposed between the first and second portions. The configuration of the annular surface of the mold member and the external surface of the core bar enables the molding apparatus to manufacture a golf club grip having an elongate cavity disposed coaxial to the longitudinal axis of the body of the grip wherein the elongate cavity is defined by first and second planer internal surfaces disposed substantially parallel to each other, a third planer internal surface disposed substantially perpendicular to the first and second planer surfaces and an arcuate internal surface disposed between the first and second internal surfaces. The grip when disposed on the cylindrical shaft of a golf club includes first, second and third elongate projections disposed substantially parallel to the longitudinal axis of the grip. The first, second and third elongate projections extend in a radial direction from the longitudinal axis of the grip and add to the width of the grip to facilitate the proper lay of the grip and the golf club in the hand of a person using the grip. These projections are beneficial to enable the grip to be securely gripped by a person who cannot make a tight fist such as one having arthritis.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 153 words
A golf club grip adapted to be mounted on a shaft of a golf club comprising, an elongate body formed from a moldable resilient material, said body having a longitudinal axis and an external surface having a substantially circular external cross sectional configuration taken approximately perpendicular to said longitudinal axis when said grip is not mounted on a shaft of a golf club, an elongate cavity disposed coaxial to the longitudinal axis of said body and adapted to receive a shaft, having a substantially cylindrically shaped external surface, of a golf club therein, said elongate cavity being defined by first and second planar internal surfaces disposed substantially parallel to each other, a third planar internal surface disposed substantially perpendicular to said first and second planar internal surfaces and an arcuate internal surface disposed between said first and second internal surfaces when said grip is not mounted on a shaft of a golf club.
Claim 2
Dependent Claim 153 words
A golf club grip adapted to be mounted on a shaft of a golf club comprising, an elongate body formed from a moldable resilient material, said body having a longitudinal axis and an external surface having a substantially circular external cross sectional configuration taken approximately perpendicular to said longitudinal axis when said grip is not mounted on a shaft of a golf club, an elongate cavity disposed coaxial to the longitudinal axis of said body and adapted to receive a shaft, having a substantially cylindrically shaped external surface, of a golf club therein, said elongate cavity being defined by first and second planar internal surfaces disposed substantially parallel to each other, a third planar internal surface disposed substantially perpendicular to said first and second planar internal surfaces and an arcuate internal surface disposed between said first and second internal surfaces when said grip is not mounted on a shaft of a golf club.
Claim 3
Dependent Claim 59 words
A golf club grip adapted to be mounted on a shaft of a golf club as defined in claim 1 wherein said third planer internal surface is interposed between said first and second planer internal surfaces and said arcuate internal surface is disposed opposite from said third planer internal surface and contiguous to said first and second internal surfaces.
Claim 4
Dependent Claim 83 words
A golf club grip adapted to be mounted on a shaft of a golf club as defined in claim 1 wherein said body includes first, second, third and fourth elongate wall portions, respectively, disposed between the external surface of said body and said first, second and third planer internal surfaces and said arcuate internal surface, said first, second and third elongate wall portions being thicker, in a direction substantially perpendicular to said longitudinal axis of said body, then said fourth elongate wall portion.
Claim 5
Dependent Claim 168 words
A golf club grip mounted on a shaft of a golf club comprising, an elongate body formed from a moldable, resilient material, said body having a longitudinal axis and an external surface, an elongate cavity disposed coaxial to the longitudinal axis of said body and receiving a shaft, having a substantially cylindrically shaped external surface, of a golf club therein, said elongate cavity being defined by first and second planar internal surfaces disposed substantially parallel to each other, a third planar internal surface disposed substantially perpendicular to said first and second planar internal surfaces and an arcuate internal surface disposed between said first and second internal surfaces, said first, second, and third planar internal surfaces conforming to the cylindrically shaped external surface of a golf club shaft received therin to expand said external surface of said body outwarly in a direction perpendicular to the longitudinal axis of said body to form first, second and third elongate projections respectively disposed substantially parallel to the longitudinal axis of said body.
Claim 6
Dependent Claim 168 words
A golf club grip mounted on a shaft of a golf club comprising, an elongate body formed from a moldable, resilient material, said body having a longitudinal axis and an external surface, an elongate cavity disposed coaxial to the longitudinal axis of said body and receiving a shaft, having a substantially cylindrically shaped external surface, of a golf club therein, said elongate cavity being defined by first and second planar internal surfaces disposed substantially parallel to each other, a third planar internal surface disposed substantially perpendicular to said first and second planar internal surfaces and an arcuate internal surface disposed between said first and second internal surfaces, said first, second, and third planar internal surfaces conforming to the cylindrically shaped external surface of a golf club shaft received therin to expand said external surface of said body outwarly in a direction perpendicular to the longitudinal axis of said body to form first, second and third elongate projections respectively disposed substantially parallel to the longitudinal axis of said body.
Claim 7
Dependent Claim 81 words
A gold club grip mounted on a shaft of a golf club as defined in claim 4 wherein said body further includes first, second, third and fourth elongate wall portions disposed between said external surface of said body and said first, second, and third planar internal surfaces and said arcuate internal surface, respectively, said first, second and third elongate wall portions being thicker, in a direction substantially perpendicular to said longitudinal axis of said body, than said fourth elongate wall portion.
Claim 8
Dependent Claim 37 words
a golf club grip mounted on a shaft of a golf club, as defined in claim 5, wherein said first, second and third elongate projections are disposed respectively on said first, second and third elongate wall portions.
