Golf club head
View Patent ↗A golf club providing improved golf ball launch conditions is disclosed herein. The golf club includes a face component and a sole comprising an elongated recess disposed proximate the face component. The elongated recess preferably is tube shaped, and preferably has an opening with a smaller width than an innermost surface of the elongated recess. The elongated recess may be a separate piece that is permanently affixed within an opening in the sole. Some embodiments of the golf club also comprise a cover affixed to the sole and at least partially covering the opening of the elongated recess, while other embodiments comprise a filler material disposed within the elongated recess or between the elongated recess and an internal surface of the face.
1. A golf club head comprising:
a face comprising a first inner surface that faces an interior cavity of the golf club head;
a sole comprising an elongated recess disposed proximate the face; and
a first filler material,
wherein the elongated recess comprises an opening and a second inner surface that faces the interior cavity, and
wherein the first filler material is disposed between the first inner surface and the second inner surface.
2. The golf club head of claim 1 , further comprising a second filler material, wherein the second filler material is disposed within the elongated recess.
3. The golf club head of claim 2 , wherein the first filler material and the second filler material are composed of different materials.
4. The golf club head of claim 1 , wherein the first filler material is a polymer.
5. The golf club head of claim 1 , wherein the first filler material is compressed between the first inner surface and the second inner surface.
6. The golf club head of claim 1 , further comprising a cover, wherein the cover is affixed to the sole and partially covers the opening.
7. The golf club head of claim 6 , wherein the sole comprises a shallow recess sized to receive the cover such that the cover is flush with the sole when the cover is disposed within the shallow recess.
8. A golf club head comprising
a face component;
a sole comprising an elongated opening proximate the face component; and
a groove insert sized to fit within the elongated opening,
wherein the groove insert comprises a tube-shaped portion, two end portions, an innermost surface, and a groove opening,
wherein the end portions of the groove insert are parallel with and permanently affixed to the sole at one or more edges of the elongated opening.
9. The golf club head of claim 8 , wherein the innermost surface has a first width, wherein the groove opening has a second width, and wherein the first width is greater than the second width.
10. The golf club head of claim 8 , wherein the groove insert is composed of a first material, wherein the sole is composed of a second material, and wherein the first material is different from the second material.
11. The golf club head of claim 8 , wherein the groove insert comprises two overlapping prongs.
12. The golf club head of claim 8 , wherein the sole is composed of a metal alloy and wherein the groove insert is composed of a polymeric material.
13. The golf club head of claim 8 , further comprising a cover, wherein the cover is affixed to the sole and partially covers the opening.
14. The golf club head of claim 13 , wherein the sole comprises a shallow recess sized to receive the cover such that the cover is flush with the sole when the cover is disposed within the shallow recess.
15. The golf club head of claim 8 , further comprising a filler material disposed within an interior cavity of the golf club head between an inner surface of the face and the groove insert.
16. The golf club head of claim 15 , wherein the filler material is compressed between the inner surface of the face and the groove insert.
17. A method of manufacturing a golf club head comprising the steps of:
providing a face cup;
providing a body having a crown, a sole, a heel, a toe, and a cutout portion, the cutout portion having a first width;
providing a groove insert comprising a second width that is smaller than the first width, an innermost surface, and an opening;
disposing the groove insert within the cutout portion;
pressing the face cup against the body such that the groove insert is trapped between the cutout portion and the face cup and the cutout portion is compressed so that it has a width equivalent to that of the second width;
welding the face cup to the body;
permanently affixing the groove insert to at least one surface of the cutout portion and at least one surface of the face cup; and
releasing the face cup and the body from compression.
18. The method of claim 17 , wherein the groove insert is composed of a polymeric material, and wherein the step of permanently affixing the groove insert to at least one surface of the cutout portion and at least one surface of the face cup is achieved by bonding.
