Abstract
A wedge type golf club head is disclosed herein where the wedge type golf club head has enhanced performance characteristics such as improved backspin, ball speed, and launch angle. More specifically, the present invention relates to a wedge type golf club head having a lower center of gravity, where the center of gravity is located substantially behind the hitting surface and substantially along a neutral axis behind the point of impact.
Claims26
A wedge type golf club head comprising:
- a hosel;
- a body attached to said hosel at a loft angle, wherein said body comprises a hitting surface and a rear portion, said hitting surface defining a neutral axis perpendicular to said hitting surface and passing through an impact point on said hitting surface;
- and
- a sole at a bottom of said body at least partially resting on a ground connecting said hitting surface and said rear portion,
- wherein said loft angle is greater than about 45 degrees, and
- wherein a center of gravity of said wedge type golf club head is located behind said hitting surface substantially along said neutral axis.
A wedge type golf club head comprising:
- a hosel;
- a body attached to said hosel at a loft angle, wherein said body comprises a hitting surface and a rear portion;
- and
- a sole at a bottom of said body at least partially resting on a ground connecting said hitting surface and said rear portion,
- wherein said loft angle is greater than about 45 degrees,
- wherein said sole further comprises a weighted portion;
- and
- wherein a density of said weighted portion is greater than a density of a remainder of said wedge type golf club head.
A wedge type golf club head comprising:
- a hosel;
- a body attached to said hosel at a loft angle, wherein said body comprises a hitting surface and a rear portion;
- and wherein said hitting surface defines a neutral axis perpendicular to said hitting surface passing through an impact point on said hitting surface;
- and
- a sole at a bottom of said body at least partially resting on a ground connecting said hitting surface and said rear portion,
- wherein said loft angle is greater than about 45 degrees, and
- wherein a center of gravity of said wedge type golf club head is located within a parabolic region of said wedge type club head that is bisected by said neutral axis, and
- wherein said parabolic region further comprises,
- a vertex located at said impact point of said hitting surface;
- and
- an open direction pointed towards said rear portion of said body.
A wedge type golf club head comprising:
- a hosel;
- a body attached to said hosel at a loft angle, wherein said body comprises a hitting surface and a rear portion;
- and wherein said hitting surface defines a neutral axis perpendicular to said hitting surface and passing through an impact point on said hitting surface;
- and
- a sole at a bottom of said body at least partially resting on a ground connecting said hitting surface and said rear portion,
- wherein said loft angle is greater than about 45 degrees, and
- wherein said wedge type golf club head has a Performance Ratio of greater than about 530,000 rpm*mph.
