Claims (33)

1. A club-head for a golf club, the club-head comprising:

a body having a top, a sole, a toe, a heel, and a front;

a face plate attached to the front of the body, the face plate having an obverse surface, a reverse surface, a peripheral zone, a toe zone, a heel zone, an upper zone, a lower zone, and a central zone, the reverse surface defining in the central zone a central recess having a thickness and a substantially annular ridge surrounding the central recess and having a maximal respective thickness, the reverse surface also defining in the toe zone and heel zone respective horizontal flanking recesses each having respective thicknesses, the reverse surface also defining in the upper zone and lower zone respective vertical flanking recesses each having respective thicknesses, and the peripheral zone having a respective thickness, wherein the maximal thickness of the annular ridge is greater than the respective thicknesses of the central recess and flanking recesses, and the respective thicknesses of the flanking recesses are no greater than the thickness of the central recess, wherein an innermost edge of the horizontal flanking recesses are spaced farther apart from the annular ridge than an innermost edge of the vertical flanking recess, the body further comprises a sole-lip, a crown-lip, a toe-lip, and a heel-lip; and

at least one of the lips further comprises at least one rib that does not touch any portion of the face plate.

2. The club-head of claim 1 , wherein the respective thicknesses of the flanking recesses are less than the thickness of the central recess.

3. The club-head of claim 1 , wherein the respective thicknesses of each of the flanking recesses are substantially equal.

4. The club-head of claim 1 , wherein the thickness of the peripheral zone is substantially equal to the thickness of the central recess.

5. The club-head of claim 1 , wherein the thickness of the face plate progressively decreases from the maximal thickness of the annular ridge to each of the flanking recesses.

6. The club-head of claim 1 , wherein:

the face plate includes a sweet spot; and

the central recess is located substantially in the center of the sweet spot.

7. The club-head of claim 6 , wherein the annular ridge is situated substantially within the sweet spot.

8. The club-head of claim 1 , wherein:

the top, sole, heel, and toe of the body have respective wall thicknesses; and

the respective thicknesses of the flanking recesses are no greater than the respective wall thicknesses of the top, sole, heel, and toe.

9. The club-head of claim 1 , wherein:

the top, sole, heel, and toe of the body have respective wall thicknesses; and

the thickness of the central recess is greater than the respective wall thicknesses of the top, sole, heel, and toe.

10. The club-head of claim 1 , wherein:

the sole-lip and crown-lip are thicker than respective wall thicknesses of the toe, heel, sole, and top of the body.

11. The club-head of claim 1 , configured as a metal-wood club-head.

12. The club-head of claim 1 , configured as an iron-type club-head.

13. A club-head for a golf club, the club-head comprising:

a body having a top, a sole, a toe, a heel, and a front;

a face plate attached to the front of the body, the face plate having an obverse surface, a reverse surface, a peripheral zone, a toe zone, a heel zone, an upper zone, a lower zone, and a central zone, the reverse surface defining in the central zone a central recess having a thickness and a substantially annular ridge surrounding the central recess and having a maximal respective thickness, the reverse surface also defining in the toe zone and heel zone respective horizontal flanking recesses each having respective thicknesses, the reverse surface also defining in the upper zone and lower zone respective vertical flanking recesses each having respective thicknesses, and the peripheral zone having a respective thickness, wherein the maximal thickness of the annular ridge is greater than the respective thicknesses of the central recess and flanking recesses, and the respective thicknesses of the flanking recesses are no greater than the thickness of the central recess, wherein an innermost edge of the horizontal flanking recesses are spaced farther apart from the annular ridge than an innermost edge of the vertical flanking recess, the body further comprises a sole-lip and crown-lip; and

each of the sole-lip and crown-lip further comprises at least one rib that does not touch any portion of the face plate.

14. A club-head for a golf club, the club-head comprising:

a body having a top, a sole, a toe, a heel, and a front;

a face plate attached to the front of the body, the face plate having an obverse surface, a reverse surface, a peripheral zone, a toe zone, a heel zone, an upper zone, a lower zone, and a central zone, the reverse surface defining in the central zone a central recess having a thickness and a substantially annular ridge surrounding the central recess and having a maximal respective thickness, the reverse surface also defining in the toe zone and heel zone respective horizontal flanking recesses each having respective thicknesses, the reverse surface also defining in the upper zone and lower zone respective vertical flanking recesses each having respective thicknesses, and the peripheral zone having a respective thickness, wherein the maximal thickness of the annular ridge is greater than the respective thicknesses of the central recess and flanking recesses, and the respective thicknesses of the flanking recesses are no greater than the thickness of the central recess, wherein an innermost edge of the horizontal flanking recesses are spaced farther apart from the annular ridge than an innermost edge of the vertical flanking recess, the body further comprises a sole-lip and a crown-lip; and

the sole-lip and crown-lip are thicker than respective wall thicknesses of the toe, heel, sole, and top of the body.

15. A club-head for a golf club, the club-head comprising:

a body having a top, a sole, a toe, a heel, and a front;

a face plate attached to the front of the body, the face plate having an obverse surface, a reverse surface, a peripheral zone, a toe zone, a heel zone, an upper zone, a lower zone, and a central zone, the reverse surface defining in the central zone a central recess having a thickness and a substantially annular ridge surrounding the central recess and having a maximal respective thickness, the reverse surface also defining in the toe zone and heel zone respective horizontal flanking recesses each having respective thicknesses, the reverse surface also defining in the upper zone and lower zone respective vertical flanking recesses each having respective thicknesses, and the peripheral zone having a respective thickness, wherein the maximal thickness of the annular ridge is greater than the respective thicknesses of the central recess and flanking recesses, and the respective thicknesses of the flanking recesses are no greater than the thickness of the central recess, wherein an innermost edge of the horizontal flanking recesses are spaced farther apart from the annular ridge than an innermost edge of the vertical flanking recess, wherein the thickness of the peripheral zone is substantially eciual to the thickness of the central recess.
