Publication number: 20100292029Abstract: A hollow wood-type golf club head having an increased weight budget and improved mass characteristics at minimum structural mass is disclosed. The club head has a striking face portion, a sole portion, a skirt portion, and a crown portion having a total surface area. A hosel portion joins the club head for connecting a shaft to the club head. The crown portion has a major crown portion and a minor crown portion, the major portion having greater surface area than the minor portion, and the major portion being displaced vertically lower relative to the minor crown portion. The major crown portion may have a generally concave curvature and the minor crown portion may have a generally convex curvature such that the major crown portion is in effect inverted with respect to the minor crown portion. The major crown portion may be upwardly inclined from the heel to the toe of the head. The head may exhibit a parabolic top view silhouette.Type: ApplicationFiled: July 26, 2010Publication date: November 18, 2010Inventors: John J. Rae, Nathaniel J. Radcliffe, Daniel J. Stone, Trent E.

Publication number: 20100285902Abstract: An exemplary golf club head having an increased amount of discretionary mass may be realized by utilizing improved drop angles, an improved average crown height, and/or articulation points. The discretionary mass may be placed low and deep in the club head to improve the location of the center of gravity as well as the inertial properties. A preferred break length may also be utilized to further improve the depth of the center of gravity. In one example, the center of gravity may be positioned to substantially align the sweet spot with the face center of the club head.Type: ApplicationFiled: July 21, 2010Publication date: November 11, 2010Applicant: SRI SPORTS LIMITEDInventors: John J.
