Golf club head with force transfer system behind face to reduce stress in and enhance compliance of face

摘要

A golf club head (100) designed to act under impact load as a bridge, comprising a face (110), the face acting as a bridge span; a force transfer system (130) located behind the face; a rear structure (140) located behind the force transfer system, the force transfer system and the rear structure acting together as a bridge truss; and an inertial support system (120) connected to the face, the inertial support system acting as a bridge support. The force transfer system and the rear face deform in a controlled manner, with the deformation reducing the stress developed in the face. The combination of the deformation of the face and the deformation of the force transfer system and rear structure result in a compliant club head with compliance occurring over a substantial portion of the face.
