ELASTIC GOLF CLUB HEAD

摘要

A golf club head (10, 12, 14), more specifically a driver head, that has deformation for center hits that is typical of current spring-effect drivers having a slightly springy face (10, 102, 159), but atypical in that it has substantially more deformation for off-center hits as compared to current designs. This is achieved by providing a shell structure (14) aft of the face 10, 102, 104) that has ample strength but also can deform in the fore-aft direction for off-center hits sufficiently to provide good spring effect for such hits, comparable to hits at the center. Current designs also change slope of the face surface for off-center hits, causing unwanted scatter of the launch angle and/or direction. That effect may also be reduced by appropriate design of the novel design. These features are accomplished by a novel spring design in the shell (14). The novel design can also be applied to other hollow wood-type heads. It can be provided with a coat or cover (157) to close openings in the shell structure (14) wherein such coat (151) makes little change in stiffness or mass of the shell.
