Faceplate backings and monolithic inserts for golf clubs
First Claim
1. A golf club head comprising:
- a front face having a recess;
a faceplate insert situated within said recess comprising a plurality of discrete pieces of the same material distributed within the recess of the striking face, the pieces having endwalls forming the striking face and each of the pieces having at least one sidewall in contact with a sidewall of an adjacent one of the pieces wherein the assembled pieces are shaped to fill the height and width of the recess in a close packed relationship;
a faceplate backing wherein the faceplate backing is situated within the recess behind at least a portion of the striking face; and
said backing being non-uniform in thickness, material or both across the extent of the faceplate in the vertical and/or horizontal direction.

Abstract
A striking face backing for golf clubs, such as a driver, iron or putter, is formed of non-uniform geometry or material arranged to create a desired “feel” to the golfer and/or produce a desired effect on the golf ball. For instance, the backing can be arranged to create a variation in mechanical properties across the striking face. The backing designs can be applied behind integral striking faces, or as part of monolithic, unitary striking face, or pixel striking face inserts. The geometry, compression, and rebound properties of the backing are communicated to the striking face. Thus a sweet spot on the striking face of the club may be enlarged and/or shifted and the effects of imperfectly executed impacts may be mitigated.
