Golf club head
View Patent ↗A golf club head comprises a loft angle no less than 18°, a striking face, a sole portion, and a top portion having an exterior surface. In an imaginary vertical plane spaced from a face center by no more than 10 mm and perpendicular to an imaginary striking face plane, an imaginary line segment has a length of 25 mm, a first endpoint located in the imaginary striking face plane, a second endpoint located above the exterior surface, and forms an angle θ with the striking face plane between 55° and 65°. The line segment is tangent to the exterior surface at a first point. A second point is located on the imaginary line segment and spaced from the first point by no less than 1 mm. The second point is spaced from the exterior surface by a gap distance that is no greater than 0.15 mm.
1. A method of manufacturing a golf club head, comprising:
referencing a location of a planar contact surface of a golf club customization device relative to the golf club head when the golf club head is oriented in a reference position relative to an imaginary ground plane and when the golf club head is fitted into the golf club customization device, the planar contact surface being a surface of the golf club customization device that contacts an upward-facing outer surface of the golf club head when the golf club head is fitted into the golf club customization device;
based on the referenced location, determining a location of an area of intended contact on the golf club head, the area of intended contact being an area of the upward-facing outer surface of the golf club head that physically contacts the planar contact surface when the club is fitted into the golf club customization device;
configuring a shape of the upward-facing outer surface of the golf club head in the area of intended contact so that the shape of the outer surface conforms to the shape of the planar contact surface;
providing the configured shape of the upward-facing outer surface in the determined area of intended contact; and
strengthening the area of intended contact against deformation by providing an internal rib that is located inside the golf club head and contacts an internal surface of the golf club head at a location corresponding to the area of intended contact.
2. The method of claim 1 , wherein the location of the area of intended contact is on a top portion of the golf club head.
3. The method of claim 2 , wherein the location of the area of intended contact is on a chamfered surface of the top portion of the golf club head.
4. The method of claim 2 , wherein, proximate the location of the area of intended contact, the top portion comprises a minimum thickness no greater than 5 mm.
5. The method of claim 1 , wherein the golf club head comprises a loft angle no less than 18°.
6. The method of claim 1 , wherein the golf club head comprises a volume no less than 50 cc.
7. The method of claim 6 , wherein the golf club head comprises a volume no greater than 150 cc.
8. The method of claim 1 , wherein the golf club head is an iron-type golf club head.
9. The method of claim 1 , wherein the planar contact surface is a surface of a downwardly-engaging jaw of a golf club clamping device.
