Golf club head with variable thickness face
A golf club head with improved striking face is disclosed. More specifically, the present invention relates to a golf club head wherein the striking face portion has two regions of increased thickness to improve the performance of the golf club head. The two regions of increased thickness may be connected via a connecting member to form an obround shaped thickened region.
1 . An iron type golf club head comprising:
a striking face portion located at a frontal portion of said iron type golf club head, adapted to strike a golf ball;
wherein said striking face portion has an external frontal surface that is substantially planar,
wherein said striking face portion has an internal rear surface that is uneven,
wherein said external frontal surface and said internal rear surface combine to define a thickness of said striking face portion, and
wherein said striking face portion further comprises;
a thickened region having an obround shape,
wherein a first end of said thickened region is located near a centroid of said striking face portion, and
wherein a second end of said thickened region is located at a location that is 15 mm upward from a ground plane, and at a distance that is a midpoint of a full length scoreline,
a body portion attached to a rear of said iron type golf club head,
wherein thickened region having said obround shape is angled at an angle α of between about 45 degrees to about 50 degrees, and
wherein said thickened region having said obround shape has a width of between about 4.0 mm to about 6.0 mm.
