Abstract
Golf club head embodiments disclosed herein comprise a crown having a stepped portion located between a front portion of the crown and rear portion of the crown, such that the crown transitions steeply in height across the stepped portion from the front portion down to the rear portion. The stepped portion of the crown may extend from adjacent to the hosel in a toeward and rearward direction.
Claims29
A golf club head comprising:
- a front portion comprising a striking face, a rear end, a toe, a heel, a crown, a sole, and a hosel;
- wherein the crown comprises front portion, a rear portion, and a stepped portion positioned between the front portion of the crown and the rear portion of the crown, wherein an external surface of the stepped portion of the crown has an angle of declination μ that is greater than an angle of declination μ of adjacent portions of the front portion and the rear portion;
- wherein the stepped portion of the crown extends from a heelward side of the crown in a toeward and rearward direction that forms an average angle α of at least about 10° relative to a plane perpendicular to the y-axis;
- and
- wherein the golf club head has a center of gravity has a z-coordinate of less than or equal to −1.4 mm.

A golf club head comprising:
- a front portion comprising a striking face, a rear end, a toe, a heel, a crown, a sole, and a hosel;
- wherein the crown comprises front portion, a rear portion, and a stepped portion positioned between the front portion of the crown and the rear portion of the crown, wherein the stepped portion of the crown provides an abrupt decrease in height in the z-axis from the front portion of the crown down to the rear portion of the crown;
- wherein the stepped portion of the crown extends from a heelward side of the crown in a toeward and rearward direction that forms an average angle α of at least about 10° relative to a plane perpendicular to the y-axis;
- and
- with the golf club head resting on a horizontal planar ground surface in the address position, a highest point of the striking face has a first height in the z-axis above the ground surface and a highest point of the crown has a second height in the z-axis above the ground surface, and the ratio of the second height divided by the first height is at least about 1.13.
