Iron-type golf club with vibration damping
The present invention relates to an iron-type golf club head which comprises a body member with a central cavity therein, a damping member and a face member disposed within the central cavity. Further, the rear surface of the body member includes an opening, preferably circular in shape. The body member is composed of a first metal material and the face member is composed of a second metal material. The damping member is preferably composed of a EPDM material.
1. An iron-type golf club head comprising:
a body member composed of a first metal material having a density between 8 g/cm 3 and 12 g/cm 3 , the body member having a rear surface, a sole surface, a crown surface, and a front surface, wherein the front surface has a central cavity therein and the rear surface has an opening therein;
a damping member disposed in the central cavity of the front surface, the damping member having a mass that ranges from 5 grams to 30 grams; and
a face member mounted in the central cavity of the front surface and disposed over the damping member, the face member composed of a second metal material;
wherein the damping member is located directly behind the front surface of the face member and around a perimeter of the face member.
2. The iron-type golf club head according to claim 1 wherein the first metal material comprises an iron alloy.
3. The iron-type golf club head according to claim 1 wherein the damping member material comprises an EPDM material.
4. The iron-type golf club head according to claim 1 wherein the damping member material comprises a viscoelastic material.
5. The iron type golf club head according to claim 1 wherein the second metal material is a titanium alloy.
6. The iron-type golf club head according to claim 1 wherein the opening in the rear surface is circular shaped.
7. An iron-type golf club head, comprising:
a body member composed of a metal material having a density between 8 g/cm 3 and 12 g/cm 3 , the body having a rear surface, a sole surface, a crown surface, and a front surface, wherein the front surface has a central cavity therein, the central cavity having a perimeter that generally parallels a perimeter of the body member, the body member having a mass that ranges from 100 grams to 240 grams;
a damping member composed of a viscoelastic material, the damping member disposed in the central cavity; and
a face member composed of a titanium alloy material mounted in the central cavity of the body member and disposed over the damping member;
wherein the damping member is located directly behind the front surface of the face member and around a perimeter of the face member.
