Oversized golf club head and golf club
First Claim
1. An oversized golf club head, comprising:
- a body defining an interior cavity, a sole portion positioned at a bottom portion of the golf club head, a crown portion positioned at a top portion, a forward portion and a rearward portion, and a face positioned at the forward portion of the body and having a roll, a bulge, a face area, a face height, and a face width, wherein;
the body has a volume greater than 550 cm3 and a head weight of less than 210 grams;
the golf club head has a Delta1 value of at least 12 mm, a CG angle that is at least 14 degrees, a head origin x-axis (CGx) coordinate between about −
2.0 mm and about 7 mm, a head origin y-axis (CGy) coordinate between about 25 mm and about 50 mm, and a head origin z-axis (CGz) coordinate between about −
7 mm and about 0 mm; and
the golf club head has a head depth of at least 125 mm, a head height of at least 70 mm, a head width of at least 120 mm, and the face area is at least 5000 mm2.

Abstract
An oversized golf club head and golf club having a large volume, large head dimensions, and/or large face characteristics, as well as unique mass property attributes driven by relationships not often considered in conforming club head design, to achieve a resistance to squaring the oversized club head during a golf swing that is comfortable to the novice golfer, a feel similar to a non-oversized golf club, stability during off-center impacts, and preferred launch characteristics. This is achieved in part via establishing a club head configuration and associated center of gravity location that results in a preferred magnitude of Delta1 and Delta2 values, CG angle, moments of inertia, and associated ratios, relationships, and club head mass property characteristics influenced by these variables, to account for the significant scale of the oversized club head and achieve improved performance.
