Abstract

A golf club head having a plurality of pores spaced along scoring lines of a face in front of a recessed top chamber thereof, and a circular through hole at the center of a back wall thereof behind the recessed top chamber for guiding air out of the recessed top chamber when striking the ball.

Claims

1. A golf club head comprising a recessed top chamber, a face disposed at a front side of said recessed top chamber for striking a golf ball, and a back wall disposed at a backside of said recessed top chamber opposite to said face, said face including a plurality of scoring lines at an outer side thereof, and further comprising:

shock absorbing means for reducing shock when the golf club head strikes a golf ball, said shock absorbing means including a plurality of pores provided in said face along said scoring lines and communicating with said recessed top chamber, and a circular hole provided at a center of said back wall and communicating with said recessed top chamber, said hole having a diameter about between 1/6 to 1/4 of a width of said face, and

reinforcing means for reinforcing the structural strength of said face including longitudinal and transverse ribs integrally formed with a backside of said face, wherein said pores are arranged between said longitudinal ribs and transverse ribs.

2. The golf club head according to claim 1, wherein said longitudinal ribs extend across said backside of said face, and said transverse ribs are arranged between said longitudinal ribs in a staggered pattern.
