Abstract

Golf club-heads are disclosed that have a body and a face plate. Exemplary club-heads are hollow metal-wood club-heads. The face plate is attached to the front of the body and has obverse and reverse surfaces, and a peripheral zone, toe zone, heel zone, upper zone, lower zone, and central zone. The reverse surface defines in the central zone a recess surrounded by a substantially annular ridge. The reverse surface also defines in the toe zone and heel zone respective horizontal flanking recesses. The reverse surface also defines in the upper zone and lower zone respective vertical flanking recesses. 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.

Claims

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 a striking 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 maximum respective thickness, 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, the body further comprises a sole lip, a crown lip, a toe lip, and a heel lip, the face plate being attached by a bond to the front of the body at the lips; and

at least one of the lips further comprises at least one rib that does not touch any portion of the face plate that is attached to the front of the body, and wherein the bond is located between the at least one rib and the face plate.

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

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

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

5. The club-head of claim 1, wherein the reverse surface is machined to form the central recess being less than the maximal thickness.

6. The club-head of claim 1, wherein the face plate comprises composite plies that are stacked and cured and form a variable thickness contour.

7. The club-head of claim 1, wherein the at least one rib includes at least two lower interior ribs located interiorly of the sole lip.

8. The club-head of claim 1, wherein the at least one rib includes at least two upper interior ribs located interiorly of the crown lip.

9. The club-head of claim 1, wherein the at least one rib includes a gusset-like configuration to stiffen a transition zone between the face plate and the body behind the crown lip.

10. The club-head of claim 1, wherein the at least one rib is vertically disposed.

11. The club-head of claim 1, wherein the at least one rib includes a gusset-like configuration to stiffen a transition zone between the face plate and the body behind the sole lip.

12. The club-head of claim 1, wherein an amount of mass removed from a corresponding lip region is less than a mass of the at least one rib to allow discretionary mass to be relocated elsewhere in the club-head.

13. The club-head of claim 1, wherein the at least one rib is located interiorly of the toe lip.

14. The club-head of claim 1, wherein the at least one rib is located interiorly of the heel lip.

15. The club-head of claim 1, wherein the at least one rib reduces the characteristic time by about 25 μ

sec.

16. The club-head of claim 1, wherein the at least one rib is configured to reduce a peak face thickness by about 0.5 mm.

17. The club-head of claim 1, wherein the at least one rib includes at least three ribs.

18. 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 a striking 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 maximum respective thickness, 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 peripheral zone, the body further comprises a sole lip, a crown lip, a toe lip, and a heel lip, the face plate being attached by a bond to the front of the body at the lips; and

at least one of the lips further comprises at least one rib that does not touch any portion of the face plate that is attached to the front of the body, and wherein the bond is located between the at least one rib and the face plate.

19. 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 a striking 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 maximum respective thickness, 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 peripheral zone, the body further comprises a sole lip, a crown lip, a toe lip, and a heel lip, the sole lip and crown lip being thicker than respective wall thicknesses of the toe, heel, sole, and top of the body, the face plate includes a sweet spot and the central recess and annular ridge are is located substantially within the sweet spot, the face plate being attached by a bond to the front of the body at the lips; and

at least one of the lips further comprises at least one rib that does not touch any portion of the face plate that is attached to the front of the body, and wherein the bond is located between the at least one rib and the face plate.

20. The club-head of claim 19, wherein the at least one rib includes a gusset-like configuration to stiffen a transition zone between the face plate and the body behind the crown lip.
