Abstract:
1. A golf club head having a more consistent trajectory and distance on impact comprising: a heel portion; a toe portion; a crown; a sole; and a face having a striking surface for striking a golf ball, the face having an ideal impact location at the center of the striking surface defining the origin of a coordinate system including a horizontal axis that extends substantially parallel to the face and generally parallel to the ground when the head is in an address position, with the positive direction of the horizontal axis pointing toward the heel portion and the negative direction of the horizontal axis pointing toward the toe portion, wherein a characteristic time at locations on the face along the horizontal axis between 40 mm and −40 mm deviates from the characteristic time at the center of the striking surface by no more that 20%, wherein one or more ribs are positioned behind the striking face to alter the stiffness of the striking surface thereby adjusting the characteristic time at various locations along the horizontal axis, and wherein the one or more ribs comprise a plurality of lower ribs spaced and centered about the ideal impact location along the bottom edge of the face.
