Abstract
Golf club heads and sets of golf club heads are provided with a thin front face for striking a golf ball and a peripheral weighting surrounding the back of the front face and defining a cavity. An insert is formed in the cavity behind at least a portion of the front face. The golf club heads may also include a weight member which is locked onto the club head by the insert.
Claims21
An iron-type club head comprising:
- (a) a front face of substantially uniform thickness, the tbickness being less than about 0.125 inches;
- (b) a perimeter weighting surrounding the front face and defining a back cavity therein;
- and
- (c) an insert located in at least a portion of the back cavity, the insert being comprised of a lower portion having a first maximum thickness and an upper portion having a second maximum thickness less than or equal to the first and having at least a portion of the upper portion having a thickness less than the first maximum thickness,
- wherein the perimeter weighting comprising an indentation adjacent the back cavity, and wherein a weight member having a specific gravity of greater than about 10 is coupled into the indentation by the insert.
The club head of claim l, wherein the insert further comprises an intermediate portion extending between the upper and lower portions and having a third maximum thickness less than or equal to the second maximum thickness.
A set of iron-type club heads wherein each of the club heads comprises:
- (a) a front face;
- (b) a perimeter weighting surrounding a substantial portion of the front face and defining a back cavity therein;
- and
- (c) an insert located in the back cavity, the insert being comprised of a lower portion having a first maximum thickness and an upper portion of having a second maximum thickness less than or equal to the first and having at least a portion of the upper portion having a thickness less than the first maximum thickness;
- and
- wherein a first club head within the set has a face thickness of less than 0.125 inches, and
- wherein each club head further comprises a weight member juxtaposed between the perimeter weighting and the insert, wherein the weight member of each club head within the set has a weight that is equal to or less than a next club head in the set with a lower club number.
An iron-type club head comprising:
- (a) a front face of substantially uniform thickness, the thickness being less than about 0.125 inches;
- (b) a perimeter weighting surrounding the front face and defining a back cavity therein;
- and
- (c) an insert located in at least a portion of the back cavity, the insert being comprised of a composite fiber reinforced resin to support the front face, wherein the insert comprises a bottom portion having a first maximum thickness and a top portion having a second maximum thickness less than the first,
- wherein a weight member having a specific gravity of greater than 10 is juxtaposed between the perimeter weighting and the insert.
