Abstract
A wood-type golf club head includes a main body and a striking wall associated with the main body. The striking wall has a striking face including a face center, a first imaginary plane tangent to the face center, and a rear surface opposite the striking face. In a second imaginary plane perpendicular to the first imaginary plane and passing through, the face center, the striking face includes a first point associated with a maximum thickness, tmax, of the striking wall, and a second point associated with a minimum thickness, tmin, of the striking wall, such that a ratio, tmax/tmin, is no less than 1.70. Also, in the second imaginary plane, the striking wall gradually tapers in thickness entirely from the first point to the second point.
Claims36
A wood-type golf club head comprising:
- a main body;
- and
- a striking wall associated with the main body, the striking wall defining a striking face that includes a face center, a striking face perimeter, and is substantially coplanar with a virtual striking face plane,
- wherein, in a virtual plane passing through the face center and perpendicular to the virtual striking face plane:
- the striking face has, specific to the virtual plane, a face length L;
- the striking wall has, specific to the virtual plane, a minimum thickness, tmin, a maximum thickness, tmax, and a first thickness region being the locus of locations on the striking face that are each associated with a thickness no less than 0.92*tmax;
- a ratio tmax/tmin is no less than 1.70;
- and
- the first thickness region extends outward from the face center by a maximum distance D1 that is no greater than 0.13*L.
A wood-type golf club head comprising:
- a main body;
- and
- a striking wall associated with the main body, the striking wall defining a striking face that includes a face center, a striking face perimeter, and is substantially coplanar with a virtual striking face plane,
- wherein, in a virtual plane that passes through the face center and is perpendicular to the virtual striking face plane, the striking face has a face length L, and the striking wall has a first thickness associated with the face center, tfc, that is no less than 4.25 mm and a second thickness, associated with a point on the striking face located no more than 0.16*L from the face center, that is no greater than 0.90*tfc.
A golf club head comprising:
- a main body;
- a striking wall associated with the main body, the striking wall defining a striking face that is generally coplanar with a virtual striking face plane, the striking face including a face center and a point spaced from the face center;
- a first coefficient of restitution value, measured at the face center, that is less than 0.83;
- and
- a second coefficient of restitution value, measured at the point spaced from the face center, that is greater than the first coefficient of restitution value, wherein a striking wall thickness associated with the point is no greater than 4.0 mm.
A wood-type golf club head comprising:
- a main body;
- and
- a striking wall associated with the main body, the striking wall having a striking face including a face center, a first imaginary plane tangent to the face center, and a rear surface opposite the striking face;
- wherein, in a second imaginary plane perpendicular to the first imaginary plane and passing through the face center:
- the striking face includes, specific to the second imaginary plane, a first point associated with a maximum thickness, tmax, of the striking wall, and a second point associated with a minimum thickness, tmin, of the striking wall, such that a ratio, tmax/tmin, is no less than 1.70;
- and
- the striking wall gradually tapers in thickness entirely from the first point to the second point.
