GOLF CLUB HEAD
First Claim
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.

Abstract
A golf club head is described having a body defining an interior cavity and comprising a heel portion, a toe portion, and a sole portion positioned at a bottom portion of the golf club head, and a crown positioned at a top portion. The body has a forward portion and a rearward portion. A face is positioned at the forward portion of the body. The face has a center face location and includes a center face characteristic time. An off-center location on the face is located at about −40 mm in a heel direction away from the center face location. The off-center location has an off-center characteristic time of at least 80% of the center face characteristic time.

18. A golf club head providing a more consistent trajectory and distance on impact resulting from a relatively constant characteristic time at points along a horizontal axis passing through an ideal impact location centered on a striking surface of the club, the club head comprising:
-
a heel portion; a toe portion; a crown; a sole; and a face comprising the striking surface, wherein the horizontal axis is generally parallel to the striking surface and the characteristic time at points along the horizontal axis between a distance of 40 mm and −
40 mm from the ideal impact location deviate less than 20% from the characteristic time at the ideal impact location, wherein the ideal impact location is offset along the horizontal axis from a center of gravity for the club head, wherein one or more ribs are positioned behind the strike face to alter the stiffness of the striking surface thereby adjusting the characteristic time at various locations along the horizontal axis. - View Dependent Claims (19, 20, 21, 22, 23)

24. A golf club head having improved hitting characteristics resulting from adjustment of a characteristic time at points along a horizontal axis passing through an ideal impact location centered on a striking surface of the club to be relatively constant across a majority of the width of the club head, the club head comprising:
-
a heel portion; a toe portion; a crown; a sole; a face comprising the striking surface, wherein the horizontal axis is generally parallel to the striking surface, wherein the ideal impact location is offset along the horizontal axis from a center of gravity for the club head, and wherein the face has a variable thickness; and a plurality of internal ribs spaced about the edge of the face, whereby the thickness of the face and the positions of the ribs are selected to adjust the characteristic time at locations along the horizontal axis between a distance of 40 mm and -40 mm from the ideal impact location to provide a relatively constant characteristic time across the face to produce a more consistent trajectory and distance on impact. - View Dependent Claims (25)

26. 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 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. - View Dependent Claims (27, 28, 29, 30, 31)
