Abstract:
A golf club incorporating a club head having a stress reducing feature located at least partially on the sole.

Claim (Index 20):
A golf club, comprising:\n a shaft ( 200 ) having a proximal end ( 210 ) and a distal end ( 220 ); a grip ( 300 ) attached to the shaft proximal end ( 210 ); and a golf club head ( 400 ) attached to the shaft distal end ( 220 ), wherein the golf club head ( 400 ) includes:\n (i) a face ( 500 ) positioned at a front portion ( 402 ) of the golf club head ( 400 ) where the golf club head ( 400 ) impacts a golf ball, opposite a rear portion ( 404 ) of the golf club head ( 400 ), wherein the face ( 400 ) includes an engineered impact point (EIP), a top edge height (TEH), a lower edge height (LEH), the face ( 500 ) has a loft of at least 12 degrees and no more than 30 degrees, and the maximum top edge height (TEH) is 1.1-2.1\u2033; \n (ii) a sole ( 700 ) positioned at a bottom portion of the golf club head ( 400 ); \n (iii) a crown ( 600 ) positioned at a top portion of the golf club head ( 400 ); \n (iv) a bore having a center that defines a shaft axis (SA) which intersects with a horizontal ground plane (GP) to define an origin point, wherein the bore is located at a heel side ( 406 ) of the golf club head ( 400 ), and wherein a toe side ( 408 ) of the golf club head ( 400 ) is located opposite of the heel side ( 406 ); \n (v) a center of gravity (CG) located:\n (a) vertically toward the crown ( 600 ) of the golf club head ( 400 ) from the origin point a distance Ycg that is less than 0.65\u2033; \n (b) horizontally from the origin point toward the toe side ( 408 ) of the golf club head ( 400 ) a distance Xcg that is generally parallel to the face ( 500 ) and the ground plane (GP); and \n (c) a distance Zcg from the origin toward the rear portion ( 404 ) in a direction generally orthogonal to the vertical direction used to measure Ycg and generally orthogonal to the horizontal direction used to measure Xcg; \n \n (vi) wherein the face ( 500 ) has a blade length (BL) measured horizontally from the origin point toward the toe side ( 408 ) of the golf club head ( 400 ) to the most distant point on the golf club head ( 400 ) in this direction, wherein the blade length (BL) includes a toe blade length section (Bbl) and a heel blade length section (Abl) measured in the same direction as the blade length (BL) from the origin point to the engineered impact point (EIP); \n (vii) a stress reducing feature ( 1000 ) including a sole located SRF ( 1300 ) located at least partially on the sole ( 700 ), wherein the sole located SRF ( 1300 ) has a SSRF length ( 1310 ) between a SSRF toe-most point ( 1312 ) and a SSRF heel-most point ( 1316 ), a SSRF leading edge ( 1320 ) having a SSRF leading edge offset ( 1322 ), a SSRF trailing edge ( 1330 ), a SSRF width ( 1340 ), and a SSRF depth ( 1350 , wherein the sole located SRF ( 1300 ) has at least one of (a) a portion of the SSRF width ( 1340 ) is at least ten percent of the Zcg distance, and (b) a portion of the SSRF depth ( 1350 ) is at least ten percent of the Ycg distance; and \n (viii) the face ( 500 ) has a characteristic time of at least 220 microseconds; \n (ix) a club moment arm (CMA) from the center of gravity (CG) to the engineered impact point (EIP) is less than 1.10\u2033; and \n (x) a portion of the golf club head ( 400 ) has a density of less than 5 g/cc.
