View Patent ↗A golf club head, according to one or more aspects of the present invention, comprises a metallic striking wall having a striking surface and at least one through score-line opening. At least one complementary component may be disposed rearward of the striking surface such that at least a part of the at least one complementary component extends into only a part of the at least one through score-line opening.
1. A golf club head comprising:
a metallic striking wall comprising a striking surface and at least one elongate through score-line opening extending across a majority of the metallic striking wall, the at least one elongate through score-line opening having a stepped portion including a ledge;
a chassis comprising a recess including a base surface, wherein the metallic striking wall is at least partially located in the recess; and
at least one complementary component rearward of the striking surface and including a base, at least a part of the at least one complementary component extending into only a part of the at least one through score-line opening, wherein the base of the at least one complementary component is interposed between the ledge of the at least one through score-line opening and the base surface of the recess.
2. The golf club head of claim 1 , wherein the metallic striking wall further comprises a thickness between about 0.6 mm and about 10 mm.
3. The golf club head of claim 2 , wherein the thickness of the metallic striking wall is between about 1 mm and about 5 mm.
4. The golf club head of claim 3 , wherein the thickness of the metallic striking wall is between about 1 mm and about 3 mm.
5. The golf club head of claim 1 , wherein the at least one complementary component comprises a non-metallic material.
6. The golf club head of claim 1 further comprising an aft portion coupled to the at least one complementary component.
7. The golf club head of claim 6 , wherein the aft portion comprises a non-metallic material.
8. The golf club head of claim 6 , wherein the aft portion comprises a constrained layer damper.
9. The golf club head of claim 1 , wherein the at least one through score-line opening is formed by hydro-jet cutting.
10. The golf club head of claim 1 , wherein the at least one through score-line opening is formed by through-slot milling.
11. A golf club head comprising:
a metallic striking wall comprising a striking surface and at least one elongate through score-line opening extending across a majority of the metallic striking wall, the at least one elongate through score-line opening including side walls formed in the metallic striking wall; and
a chassis comprising a recess having a base surface and at least one protrusion extending from the base surface, at least a part of the at least one protrusion extending into only a part of the at least one through score-line opening and having an anterior surface recessed in its entirety from the striking surface, wherein at least a portion of the side walls of the at least one elongate through score-line opening and at least a portion of the anterior surface of the at least one protrusion are visually exposed and delimit at least a portion of at least one face groove.
12. The golf club head of claim 11 , wherein the metallic striking wall further comprises a thickness between about 0.6 mm and about 10 mm.
13. The golf club head of claim 12 , wherein the thickness of the metallic striking wall is between about 1 mm and about 5 mm.
14. The golf club head of claim 13 , wherein the thickness of the metallic striking wall is between about 1 mm and about 3 mm.
15. The golf club head of claim 11 , wherein the at least one through score-line opening is formed by hydro-jet cutting.
16. The golf club head of claim 11 , wherein the at least one through score-line opening is formed by through-slot milling.
17. The golf club head of claim 16 , further comprising a non-metallic material.
18. The golf club head of claim 17 , further comprising a top-line wall including at least one through aperture, the non-metallic material extending into at least a part of the at least one through aperture.
19. The golf club head of claim 17 , wherein the metallic striking wall further comprises at least one through cavity, the non-metallic material extending into at least a part of the at least one through cavity.
20. The golf club head of claim 11 , further comprising a constrained layer damper.
