Golf Clubs and Golf Club Heads with Adjustable Center of Gravity and Moment of Inertia Characteristics
First Claim
1. A golf club head, comprising:
- a club head body member having a ball-striking face, a sole, a cavity defined in the club head body member rearward of the face, an upper end, a toe end and a heel end, wherein the heel end is adjacent to a shaft-connecting member, the club head body member further having a hole located within the cavity;
an insert member engaged at least partially within the cavity such that the insert member is rotatable between different positions, the insert member having an aperture extending completely therethrough; and
a fastener passing through the aperture and engaged with the hole in the club head body member to secure the insert member to the club head body member,wherein the insert member is configured such that rotation of the insert member shifts the center of gravity of the golf club head.

Abstract
Golf clubs, club heads, and club weighting systems may include: (a) a club head body member; and (b) one or more weight members removably and/or movably engaged with the club head body member so as to move between a first position and a second position to change an overall exterior shape of the club head. This shape change may result in changes to the overall center of gravity, weighting, and/or moment of inertia characteristics of the club head. Alternatively or additionally, the weight member(s) may be removed from the club head body member, reoriented, and/or replaced with a different weight member, e.g., to change the overall exterior shape, center of gravity, weighting, and/or moment of inertia characteristics of the club head. Methods of making and using these clubs, club heads, and weighting systems also are described.
