Patent ID: 8602909

Claim:
A high volume aerodynamic golf club head ( 100 ) comprising: A) a hollow body ( 110 ) having a club head volume of at least 400 cc, a face ( 200 ), a sole section ( 300 ), a crown section ( 400 ), a front ( 112 ), a back ( 114 ), a heel ( 116 ), and a toe ( 118 ); B) the crown section ( 400 ) having a crown apex ( 410 ) located an apex height (AH) above a ground plane (GP), wherein: (i) within a front-to-back vertical section through the crown apex ( 410 ) and perpendicular to a vertical plane created by a shaft axis (SA), a portion of the crown section ( 400 ) between the crown apex ( 410 ) and the face ( 200 ) has an apex-to-front radius of curvature (Ra-f) that is less than 3 inches; (ii) within a heel-to-toe vertical section through the crown apex ( 410 ) and parallel to the vertical plane created by the shaft axis (SA), a portion of the crown section ( 400 ) has a heel-to-toe radius of curvature (Rh-t) that is less than 4 inches; and (iii) a portion of the crown section ( 400 ) between the crown apex ( 410 ) and the back ( 114 ) of the hollow body ( 110 ) has an apex-to-rear radius of curvature (Ra-r), and the apex-to-front radius of curvature (Ra-f) in contact with the crown apex ( 410 ) is at least 25% less than the maximum apex-to-rear radius of curvature (Ra-r); and C) the face ( 200 ) having a top edge ( 210 ) and a lower edge ( 220 ), wherein a top edge height (TEH) is the elevation of the top edge ( 210 ) above the ground plane (GP), and a lower edge height (LEH) is the elevation of the lower edge ( 220 ) above the ground plane (GP), wherein a maximum top edge height (TEH) is at least 2 inches.
