Reinforced metal golf club head

A golf club head comprising an enclosed metal body in the shape of a head for a golf driver, the metal body having:

• a. a front striking face of predetermined height and width,
• b. a sole of predetermined length and width,
• c. a back side,
• d. a toe,
• e. a heel,
• f. a top side of predetermined length and width, and
• g. a hosel positioned adjacent the heel,
• wherein the metal body has an integral cavity formed by internal surface of the striking face, the sole, the back side, the toe, the heel, and the top side and wherein at least one rib extends along and between the internal source of the striking face and the internal surface of the top side to reinforce both the striking face and the top side and wherein the rib comprises a first element of substantially uniform cross-sectional area extending along more than half of the height of the internal surface of the striking face and a second member interconnecting the top side and the striking face and extending for less than half of the length of the top side and extending for less than half of the height of the striking face.

• a. a font striking face of predetermined height and width,
• b. a sole of predetermined length and width,
• c. a back side,
• d. a toe,
• e. a heel,
• f. a top side of predetermined length and width, and
• g. a hosel positioned adjacent the heel,
• wherein metal body has an internal cavity formed by internal surfaces of the striking face, the sole, the back side, the toe, the heel, and the top side and wherein the top side includes a plurality of molded, integral corrugations, the corrugations defining alternating reinforcing protrusions and depressions, the reinforcing protrusions extending rearwardly from a location short of the striking face.

A method of fabricating a golf club head comprising an enclosed metal body in the shape of a head for a golf driver, comprising the steps of:

• forming a first part of the metal body, said first part having:
• a. a front striking face of predetermined height, width, and contour,
• b. an opening at the sole of predetermined length, width, and contour,
• c. a back side,
• d. a toe,
• e. a heel,
• f. a top side of predetermined length and width, and
• g. a hosel positioned adjacent the heel;
• forming a sole plate for positioning in the opening having the same length, width and contour as the predetermined opening at the sole of the first part and having at least one integrally formed sole ridge extending along a portion of its length;
• and
• fixing said sole plate in said opening such that the metal body has an internal cavity formed by internal surfaces of the striking face, the sold plate, the back side, the toe, the heel, and the top side.
