Abstract:
An aerodynamic golf club head with a low center of gravity and producing reduced aerodynamic drag forces. The club head has crown section attributes that impart beneficial aerodynamic properties.

Claim (Index 19):
An aerodynamic golf club head comprising:\n 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 ), a toe ( 118 ), and a front-to-back dimension (FB) of at least 4.4 inches, wherein\n i) the hollow body ( 110 ) has a bore having a center that defines a shaft axis (SA) which intersects with a horizontal ground plane (GP) to define an origin point; and \n ii) the hollow body ( 110 ) has a center of gravity (CG) located:\n (a) vertically toward the crown section ( 400 ) from the origin point a distance Ycg in a direction orthogonal to the ground plane (GP), and vertically toward the crown section ( 400 ) from a horizontal center face plane a distance Vcg in a direction orthogonal to the horizontal center face plane, wherein the distance Vcg is less than or equal to 0 inches; \n (b) horizontally from the origin point toward the toe ( 118 ) a distance Xcg that is parallel to a vertical plane defined by the shaft axis (SA) and parallel to the ground plane (GP); and \n (c) a distance Zcg from the origin toward the back ( 114 ) in a direction orthogonal to the vertical direction used to measure Ycg and orthogonal to the horizontal direction used to measure Xcg; \n \n B) 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 portion of the top edge height (TEH) is at least 2 inches; and C) the crown section ( 400 ) having a crown apex ( 410 ) located an apex height (AH) above the ground plane (GP), wherein;\n i) the crown apex ( 410 ) is located behind the forwardmost point on the face ( 200 ) a distance that is a crown apex setback dimension ( 412 ) measured in a direction toward the back ( 114 ) and orthogonal to the vertical direction used to measure Ycg and orthogonal to the horizontal direction used to measure Xcg; \n ii) the crown apex ( 410 ) is located a distance from the origin toward the toe ( 118 ) a crown apex x-dimension ( 416 ) distance that is parallel to the vertical plane defined by the shaft axis (SA) and parallel to the ground plane (GP); iii) the crown section ( 400 ) includes a post apex attachment promoting region ( 420 ) on the surface of the crown section ( 400 ) at an elevation above a maximum top edge plane (MTEP) wherein the post apex attachment promoting region ( 420 ) begins at the crown apex ( 410 ) and extends toward the back ( 114 ); \n iv) a portion of the crown section ( 400 ) at an elevation above the maximum top edge plane (MTEP) is composed of nonmetallic material and wherein the crown section ( 400 ) at the crown apex ( 410 ) is composed of nonmetallic material; and \n v) a portion of the crown section ( 400 ) at an elevation above the maximum top edge plane (MTEP) has at least one of:\n (a) 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), wherein the portion of the apex-to-front radius of curvature (Ra-f) in contact with the crown apex ( 410 ) is less than 3 inches; \n (b) 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), wherein at least a portion of the apex-to-rear radius of curvature (Ra-r) is greater than 5 inches; or \n (c) a portion of the crown section ( 400 ) has a heel-to-toe radius of curvature (Rh-t), wherein the portion of the heel-to-toe radius of curvature (Rh-t) in contact with the crown apex ( 410 ) is less than 4 inches; and \n \n D) the golf club head includes an adjustable loft system.
