Abstract

A golf club head designed to act under impact load as a bridge comprising a face; an inertial support system; a rear structure; and a force transfer system, under impact load the force transfer system, in cooperation with the inertial support system, elongating the rear structure and controlling the bending of the face, the pattern of bending of the face being a substantially bridge-like pattern of bending or a substantially modified bridge-like pattern of bending.

Claims

1. A golf club head comprising:

a face, the face comprising a front side and a back side; and

a face-supporting structure, the face-supporting structure connected to the back side of the face at at least two points;

in a substantially on-center impact with a golf ball, the face deforming, with respect to the face-supporting structure, a first amount and the face-supporting structure deforming a second amount; and

in an off-center impact, the face-supporting structure deforming at an amount greater than the second amount when the face deforms, with respect to the face-supporting structure, at an amount less than the first amount, the changes in the amounts resulting in a club head with approximately the same compliance occurring over a portion of the face.

2. The golf club head according to claim 1 in which the portion of the face comprises at least approximately 25% of the face.

3. The golf club head according to claim 1 in which the face-supporting structure is a force transfer system or a force transfer system and a rear structure, the proximal side of the rear structure connected to the distal side of the force transfer system at at least one point.

4. The golf club head according to claim 3 in which the golf club head further comprises an inertial support system, the inertial support system connected to the face-supporting structure or connected to the edges of the face, the mass of the inertial support system being at least approximately equal to the combined mass of the face and the face-supporting structure.

5. The golf club head according to claim 1 in which at least a portion of the face-supporting structure is separated into a top portion and a bottom portion, the top portion of the portion of the face-supporting structure connected to the face at at least two points and the bottom portion of the portion of the face-supporting structure connected to the face at at least two points.

6. The golf club head according to claim 1 further comprising:

a torsion control system, the torsion control system connected to the back side of the face at at least one point or to the proximal side of the rear structure at at least one point, during off-center impact the torsion control system controlling the internal rotation of at least a portion of the face-supporting structure.

7. The golf club head according to claim 6 in which the torsion control system comprises a cross-brace, an insert, a combination of a cross-brace and an insert, or a combination of a cross-brace and a portion of an insert.

8. The golf club head according to claim 7 in which the insert comprises a constant wall thickness, a multiple wall thickness, a varying wall thickness, or a profiled wall thickness.

9. The golf club head according to claim 6 in which the torsion control system is re-configurable or replaceable.

10. The golf club head according to claim 1 in which the golf club head further comprises a crown.

11. The golf club head according to claim 1 in which the golf club head further comprises a sole.
