VARIABLE THICKNESS FACE PLATE FOR A GOLF CLUB HEAD
First Claim
Patent Images
1. A golf club head having a normalized characteristic time comprising:
- a body having a crown portion, a sole portion, a toe portion, a heel portion, and a rear portion defining an inner cavity;
a face plate having;
a front surface;
a rear surface;
a geometric center defining the origin of a coordinate system having a horizontal axis extending from near the heel portion to near the toe portion, and a vertical axis extending from near the crown portion to near the sole portion, perpendicular to the horizontal axis;
a thickness measured between the front surface and the rear surface, wherein the thickness varies at different locations across the face plate to define a variable thickness profile, the variable thickness profile comprising;
a peripheral region comprising a minimum thickness of the face plate;
a transition region; and
a central region comprising a maximum thickness of the face plate, the central region having an ovular shape with a major axis that extends at an angle between 2 degrees and 60 degrees from the vertical axis.
