GOLF CLUBS AND GOLF CLUB HEADS WITH ADJUSTABLE CENTER OF GRAVITY AND MOMENT OF INERTIA CHARACTERISTICS |
摘要 |
<p>Golf clubs, club heads, and club weighting systems may include: (a) a club head body member; and (b) one or more weight members 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.</p> |
