Abstract
A multi-piece iron-type golf club head with a substantial weight member is disclosed and claimed. The golf club head includes a plurality of body members. A first body member includes a face, a rear surface, and a hosel. A viscoelastic material is attached to the rear surface, and a second body member is attached to the viscoelastic material. The second body member, which may be a weight member, has a substantially larger mass than in known golf clubs.
Claims16
An iron-type golf club head, comprising:
- a first body member including a face, a rear surface, and a hosel;
- a viscoelastic material coupled to said rear surface;
- and
- a second body member coupled to said viscoelastic material;
- wherein said second body member is a weight member with a mass of at least 10 grams;
- wherein at least a portion of said rear surface has a concave profile extending from a heel of said club head to a toe of said club head and viscoelastic material is coupled to said rear surface within said concave profile;
- and
- wherein the club head further comprises a center of gravity and a moment of inertia measured about a vertical axis passing through said center of gravity from approximately 2400 g·cm2 to approximately 2900 g·cm2.

A set of golf clubs, comprising:
- a plurality of golf club heads, wherein each head includes:
- a first body member including a face, a rear surface, and a hosel;
- a second body member coupled to said rear surface;
- a viscoelastic material intermediate said first and second body members;
- and
- a center of gravity and a moment of inertia measured about a vertical axis passing through said center of gravity;
- wherein each of said moments of inertia are substantially the same;
- and
- wherein a difference between a maximum and a minimum of said moments of inertia is 40 g·cm2 or less.
