US 7,803,067 B2 · Golf club head

Abstract

A golf club head according to one or more aspects of the present invention comprises a sole portion, a crown portion, and a stiffening element associated with at least one of the crown portion and the sole portion. The stiffening element has a survey length and at least one welded portion, comprising less than about 70% of the survey length. The stiffening element further comprises a plurality of welded portions. The welded portions adjacent each other are separated by a distance between about 10 mm and about 100 mm. A method of producing a golf club head comprises identifying a plurality of high-deflection regions having a plurality of ranges and providing a stiffening element, at least in part coupled with the plurality of high-deflection regions. The stiffening element comprises a plurality of heights and/or widths corresponding to the plurality of deflection ranges. At least one of the plurality of heights and/or widths is different from at least another of the plurality of heights and/or widths.

A golf club head comprising:

a strike face comprising a top edge and a center apex;
a hosel having a hosel centerline, wherein the club head is oriented relative to an imaginary horizontal ground plane so that the hosel centerline is in an imaginary vertical plane generally parallel to the top edge of the strike face, the hosel centerline oriented at an angle of 60° relative to the imaginary horizontal ground plane;
a sole portion;
a crown portion;
a plurality of high deflection regions located on at least one of the crown portion and the sole portion;
and
a stiffening element comprising a width between about 0.2 mm and about 5 mm, a height between about 1 mm and about 25 mm, and a survey length characterized by a maximum horizontal length of the stiffening element in a top plan view, wherein the stiffening element is coupled, at least in part, with the plurality of high-deflection regions by at least one discrete welded portion extending a distance of less than about 70% of the survey length.
