Abstract
A golf club head with an improved sole profile is disclosed herein. More specifically, the present invention discloses various types of irons, including wedges, having a toe portion, a heel portion, and a center portion therebetween, in which a camber radius of a sole as measured from a front to a back of the golf club head changes moving from the toe portion through the center portion to the heel portion. In addition, a bounce angle of the golf club head also changes moving from the toe portion through the center portion to the heel portion. The resulting golf club head improves performance, as this new sole profile allows specific portions of the sole to have a profile that meets the needs at that location.
Claims26
A golf club head, comprising:
- a) a striking face located at a frontal portion of the golf club head, the striking face having a plurality of scorelines;
- b) a back portion located opposite the striking face;
- c) a topline located at an upper portion of the golf club head;
- d) a heel portion located at a proximal end of the golf club head;
- e) a hosel adjacent to the heel portion and the topline, the hosel defining a longitudinal axis and configured to receive a shaft;
- f) a toe portion located at a distal end of the golf club head opposite the heel portion;
- g) a center portion located in between the heel portion and the toe portion;
- h) a sole located at a lower portion of the golf club head opposite the topline, the sole having a camber radius;
- i) a leading edge adjacent to the striking face and the sole;
- j) a trailing edge adjacent to the back portion and the sole, wherein the camber radius is measured from the leading edge to the trailing edge;
- and
- k) wherein the camber radius changes from the toe portion to the heel portion,
- l) Wherein a bounce line from the leading edge to the trailing edge defines a bounce angle with a ground plane when the longitudinal axis of the hosel is oriented perpendicular to the ground plane, and the bounce angle changes from the toe portion to the heel portion.
A golf club head, comprising:
- a) a striking face located at a frontal portion of the golf club head, the striking face having a plurality of scorelines;
- b) a back portion located opposite the striking face;
- c) a topline located at an upper portion of the golf club head;
- d) a heel portion located at a proximal end of the golf club head;
- e) a hosel adjacent to the heel portion and the topline, the hosel configured to receive a shaft;
- f) a toe portion located at a distal end of the golf club head opposite the heel portion;
- g) a center portion located in between the heel portion and the toe portion;
- h) a sole located at a lower portion of the golf club head opposite the topline;
- i) a leading edge adjacent to the striking face and the sole;
- j) a trailing edge adjacent to the back portion and the sole,
- k) wherein the sole defines a camber radius from the leading edge to the trailing edge, wherein the camber radius changes when measured from the toe portion compared to when measured from the heel portion, wherein the camber radius progressively increases from the toe portion to the center portion, then decreases from the center portion to the heel portion.
A golf club head, comprising:
- a) a striking face located at a frontal portion of the golf club head, the striking face having a plurality of scorelines;
- b) a back portion located opposite the striking face;
- c) a topline located at an upper portion of the golf club head;
- d) a heel portion located at a proximal end of the golf club head;
- e) a hosel adjacent to the heel portion and the topline, the hosel defining a longitudinal axis and configured to receive a shaft;
- f) a toe portion located at a distal end of the golf club head opposite the heel portion;
- g) a center portion located in between the heel portion and the toe portion;
- h) a sole located at a lower portion of the golf club head opposite the topline;
- i) a leading edge adjacent to the striking face and the sole;
- and
- j) a trailing edge adjacent to the back portion and the sole,
- k) wherein a bounce line from the leading edge to the trailing edge defines a bounce angle with a ground plane when the hosel is oriented perpendicular to the ground plane, and wherein the bounce angle changes from the toe portion to the heel portion.
