US Patent 7169062 Golf club head having uniform deformation structure

A golf club head includes a golf club head body, a striking plate and a plurality of equal-length buffers. In assembling, the striking plate mechanically connects to a front side of the golf club head body. Each of the equal-length buffers radially extends from an outer periphery to a center portion on a rear surface of the striking plate, and performs identical elastic deformation. Each of the equal-length buffers has an inner end adapted to commonly delimit a configuration for a striking zone substantially similar to that of the outer periphery of the striking plate.
