Abstract
Embodiments of a golf club head with a plurality of energy storage features are presented herein. In some embodiments, a golf club head comprises a body comprising a strike face, a heel region, a toe region opposite the heel region, a sole, a crown, a channel, a chamfer spanning between a strike face and the crown, and an internal radius transition feature from the strike face to at least one of the sole or the crown.
Claims20
A golf club head comprising:
- a hollow body;
- a strike face defining a loft plane;
- a heel region;
- a toe region opposite the heel region;
- a sole;
- a crown;
- a channel located behind the strike face and on the sole of the golf club head, the channel comprising:
- a front edge adjacent to the sole;
- a rear edge adjacent to the sole;
- a main portion extending inward from the sole between the front edge and the rear edge, the main portion comprising:
- a front wall, a rear wall, and an apex positioned along a tallest portion of the channel relative to the sole and extending from the heel region to the toe region, the apex separating the front wall from the rear wall, wherein:
- the front wall extends from the front edge to the apex;
- the rear wall extends from the rear edge to the apex;
- and
- a curvature of the rear wall is concave to the front wall defining a cambered rear wall;
- wherein the cambered rear wall promotes the flexing of the channel;
- wherein the sole and the channel are formed from a single material;
- wherein the rear wall of the channel has a radius of curvature that is between 2.0 inches and 2.5 inches;
- wherein the channel comprises a triangular shape;
- wherein the channel is rounded near the apex.
A golf club head comprising:
- a hollow body;
- a strike face defining a loft plane;
- a heel region;
- a toe region opposite the heel region;
- a sole;
- a crown;
- a channel located behind the strike face and on the sole of the golf club head, the channel comprising:
- a front edge adjacent to the sole;
- a rear edge adjacent to the sole;
- a main portion extending inward from the sole between the front edge and the rear edge, the main portion comprising:
- a front wall, a rear wall, and an apex positioned along a tallest portion of the channel relative to the sole and extending from the heel region to the toe region, the apex separating the front wall from the rear wall, wherein:
- the front wall extends from the front edge to the apex;
- the rear wall extends from the rear edge to the apex;
- and
- wherein the golf club head further comprises a transition region extending rearward from the strike face to the sole and between the strike face and the channel, the transition region comprising:
- a first tier extending from the strike face;
- a first tier transition region extending from the first tier opposite the strike face;
- a second tier extending from the first tier transition region opposite the first tier;
- wherein:
- the first tier comprises a first thickness that is substantially constant or decreasing from the strike face to the first tier transition region;
- the second tier comprises a second thickness that is substantially constant or decreasing from the first tier transition region, wherein the second thickness is smaller than the first thickness.
A golf club head comprising:
- a hollow body;
- a strike face defining a loft plane;
- a heel region;
- a toe region opposite the heel region;
- a sole;
- a crown;
- a Z-shaped channel located behind the strike face and on the sole of the golf club head, the Z-shaped channel comprising:
- a front edge adjacent to the sole;
- a rear edge adjacent to the sole;
- a main portion extending inward from the sole between the front edge and the rear edge, the main portion comprising:
- a front wall, a rear wall, and an apex positioned along a tallest portion of the Z-shaped channel relative to the sole and extending from the heel region to the toe region, the apex separating the front wall from the rear wall, wherein:
- the front wall extends from the front edge to the apex;
- the rear wall extends from the rear edge to the apex;
- and
- the rear wall is concave to the front wall;
- the front wall comprises an inset portion, wherein:
- the front wall and the inset portion define a 45 degree angle relative to a ground plane;
- wherein the sole and the Z-shaped channel are formed from a single material;
- wherein the rear wall of the Z-shaped channel has a radius of curvature that is between 2.0 inches and 2.5 inches;
- a transition region extending rearward from the strike face to the sole and between the strike face and the Z-shaped channel, the transition region comprising:
- a first tier extending from the strike face;
- a first tier transition region extending from the first tier opposite the strike face;
- a second tier extending from the first tier transition region opposite the first tier;
- wherein:
- the first tier comprises a first thickness that is substantially constant or decreasing from the strike face to the first tier transition region;
- the second tier comprises a second thickness that is substantially constant or decreasing from the first tier transition region, wherein the second thickness is smaller than the first thickness.
