摘要:
A golf club is provided having a hollow body golf club head comprising discrete concentrations of weight or mass located away from the center of gravity or the geometric center of the club head to optimize the moment of inertia of the club head about both the vertical axis running through the center of gravity or geometric center of the club head, hereinafter referred to as the “y-axis,” and the axis running through the center of the shaft of the golf club, hereinafter referred to as the “hosel axis.” The ratio of moment of inertia of the club head about the y-axis to moment of inertia of the club head about the hosel axis is preferably 0.55. More preferably, this ratio is 0.75.

A golf club incorporating an interchangeable shaft system includes a shaft, a shaft sleeve, a club head. The shaft sleeve is coupled to an end of the shaft and is received in a hosel included in the club head. The shaft sleeve is removably coupled to the club head. Hosel and shaft sleeve alignment features provide discreet orientations between the shaft and club head.

A golf club head with an improved sweet spot, defined as a portion of the striking face that has at least 99.7% of the maximum ballspeed is disclosed herein. More specifically, the present invention discloses a golf club head with a significantly circular sweet spot that encompasses at least about 1.5% of the total striking face. A golf club head in accordance with the present invention may generally have a improved face geometry with an elliptical factor of greater than about 0.5, a beveled transition portion around the striking face of the golf club head, a variable face thickness region with decreases thickness, or even a tilted bulge and roll radius all helping improve the performance of the golf club head.

A golf club head is presented comprising a sole including a weight member secured to the sole via a non-threaded attachment assembly. Further, the weight member has a large surface area relative to its thickness, resulting in a chip-like or wafer-like weight member. This design allows the mass of the weight member to be spread substantially along the surface of the sole as opposed to in the interior of the club head. The golf club head may comprise more than one weight member.
摘要:
A golf club head having at least two discrete weight members positioned on the sole to optimize moment of inertia is disclosed. A first weight member is located toward and substantially parallel with the face edge of the sole. A second member is located toward the back of the sole and substantially centered between the heel and toe edges of the sole. In one embodiment, a golf club head includes a sole comprising four sections and wherein a rib of material connects two of said sections. In another embodiment, a golf club head includes a cavity formed between the crown and sole and having an opening at the back of the club head. In yet another embodiment, a golf club head is tapered to form a waist and has a back that has a bowed-shape.
摘要:
A golf club head with low and high density zones designed to provide specific densities for use in various parts of the club head to achieve maximum volume and properties within specific weight goals. The low and high density zones may be formed from laminates having different equivalent densities than the layers used to form the laminates.

A plurality of golf club heads wherein the difference in spin is minimized is disclosed herein. More specifically, the present invention discloses a plurality of fairway wood type golf club head with a volume of between about 110 cubic centimeters (cc) and about 250 cc, wherein the change in backspin between any two clubs within the plurality of metal wood type golf club heads is less than about 600 revolutions per minute (rpm). A plurality of golf clubs in accordance with the present invention may generally have all of its clubs maintain a center of gravity (CG) location that is less than about 8.0 mm away from a neutral axis of the golf club head regardless of the difference in loft of the specific golf club head within the plurality of golf club heads.
