A golf club head according to one or more aspects of the present invention may include a main cavity having at least one auxiliary cavity and a base surface. An insert may be associated with the base surface and may comprise at least two contact elements, with a bridge member disposed therebetween. Different contact elements of the insert may be disposed in separate respective auxiliary cavities, such that each contact element may be associated with the base surface. The bridge member of the insert may be dissociated from the base surface. Moreover, a surface coating may be selectively applied to the head to permit a durable adhesive bond between the insert and the base surface.
1. A golf club head comprising:
a base surface;
a perimeter-weighting element surrounding the base surface and including a top-line portion, a sole portion, a heel portion, and a toe portion, wherein each of the top-line portion, the sole portion, the heel portion, and the toe portion extend rearwardly away from the base surface;
a main cavity delimited by the base surface and the perimeter-weighting element;
a first sub-cavity and a second sub-cavity positioned within the main cavity; and
a unitary body including at least a first portion and a second portion, the first portion disposed in the first sub-cavity and the second portion disposed in the second sub- cavity, at least a portion of the unitary body contacting the base surface, wherein at least a portion of the unitary body is recessed within the perimeter-weighting element.
2. The golf club head of claim 1 , further wherein the first sub-cavity is between the top-line portion and the second sub-cavity.
3. The golf club head of claim 2 , further wherein the second sub-cavity is between the first sub-cavity and the sole portion.
4. The golf club head of claim 1 , further wherein the main cavity further includes a third sub-cavity and a fourth sub-cavity.
5. The golf club head of claim 1 , wherein the unitary body includes a stiffening member.
6. The golf club head of claim 5 , wherein the unitary body is constructed out of a different material than the stiffening member.
7. The golf club head of claim 5 , wherein the stiffening member is constructed out of a polymer.
8. The golf club head of claim 6 , wherein the stiffening member is positioned flush with the unitary body.
9. The golf club head of claim 6 , wherein the stiffening member is attached to the unitary body.
10. The golf club head of claim 6 , wherein the stiffening member is integrally co-molded with the unitary body.
11. The golf club head of claim 1 , wherein the unitary body is constructed out of a homogeneous material.
12. The golf club head of claim 1 , wherein the base surface comprises a vibration-attenuating feature.
