Abstract
A golf club head with a front wall, a rear wall and a reinforced crown includes ribs in the crown that are spaced more closely together near the front wall than near the rear wall. Preferably, the ribs radiate from a point in space located forward of the front wall. This arrangement of ribs significantly increases the fundamental structural frequency of the club head and significantly reduces the peak stress in the crown of the club head when compared with ribs extending perpendicular to the front wall and parallel to each other.
Claims19
A golf club head comprising:
- a hollow metal body having a heel end, a toe end, a crown, a sole, a front wall and a skirt, said skirt extending between said heel and toe ends forming a rear wall, said crown having an upper surface and a lower surface;
- a plurality of narrow, elongate, generally straight, metallic, shock wave distributing ribs extending downward from said lower surface of said crown, each rib of said plurality of ribs extending from a first end proximal said front wall to a second end proximal said rear wall, said ribs being spaced apart by a greater amount at said second ends than at said first ends;
- each rib of said plurality of ribs having a longitudinal axis;
- and
- at least three of said longitudinal axes radiating from and intersecting at a point forward of said front wall.
