Abstract

Embodiments of golf club heads with turbulators and methods to manufacture golf club heads with turbulators are generally described herein. In many embodiments, the turbulators are located on the crown and include a plurality of ridges disposed on the crown. Each ridge includes a base, a top surface, a ridge apex, a front surface, and a rear surface. The turbulators are positioned on the forward most portion of the crown. Other embodiments may be described and claimed.

First claim

The invention claimed is:

1. A golf club head comprising:
a crown, a sole, a toe end, a heel end, a face portion defining a loft plane, a rear portion, and a leading edge between the face portion and the crown; and
a turbulator including a plurality of ridges disposed on the crown, wherein each ridge of the plurality of ridges includes:
a base positioned directly adjacent to the crown;
a top surface opposite the base of the ridge;
a ridge apex defined as a maximum height of the ridge measured in a direction perpendicular from the base of the ridge;
a front surface comprises a first end closest to the face portion and a second end closest to the ridge apex; and
a rear surface defining a portion of the ridge being closest to the rear portion of the golf club head, extending from behind the ridge apex towards the rear portion of the club head;
wherein:
the turbulator is positioned in a forward one-third portion of the crown in a front end to a rear end direction;
the front surface defines a portion of the ridge being closest to the face portion, extending from near the face portion towards the rear portion of the club head; and
the ridge apex of each ridge of the plurality of ridges is positioned within the first 50% of the ridge length.

2. The golf club head of claim 1 , wherein the front surface is angled from the loft plane, where the angle comprises a range from 87 degrees to 100 degrees.

3. The golf club head of claim 1 , wherein at least one of the front surface, the top surface, or the rear surface of each ridge of the plurality of ridges includes at least two angled planar surfaces.

4. The golf club head of claim 1 , wherein the ridge apex of each ridge of the plurality of ridges is positioned within the first 35% of the ridge length.

5. The golf club head of claim 1 , wherein each ridge of the plurality of ridges further comprises: a pair of side walls extending from the base to the top surface, and wherein each side wall tapers towards the top surface at an angle of no less than 60 degrees.

6. The golf club head of claim 1 , wherein the top surface extending between the front surface and the rear surface, the top surface having a width extending in a direction from the heel end to the toe end of the club head.

7. The golf club head of claim 6 , wherein the base extends an entire length of the ridge in a direction from the front surface to the rear surface of the ridge; and
the base having a width extending in a direction from the heel end to the toe end of the club head, wherein the width of the top surface is at least 50-90% of the width of the base.

8. The golf club head of claim 1 , wherein the leading edge comprises a leading edge plane forming a leading edge angle with the loft plane, wherein the first end of the front surface of each ridge of the plurality of ridges being at least partly located between the leading edge plane and the rear portion, but not extending beyond the leading edge plane.

9. The golf club head of claim 8 , wherein the first end of the front surface is positioned on the leading edge.

10. The golf club head of claim 1 , wherein: each adjacent pair of ridges is separate and spaced apart to define a space between the adjacent pair of ridges, and each ridge extends between the heel portion and the toe portion to define a width and extends between the face portion and the rear portion to define a length;
the length is substantially greater than the width for each ridge of the plurality of ridges;
the space between each adjacent pair of ridges is substantially greater than the width of each of the adjacent pair of ridges that define the space.

11. A golf club head comprising:
a crown, a sole, a toe end, a heel end, a face portion, a rear portion, and a leading edge between the face portion and the crown; and
a turbulator including a plurality of ridges disposed on the crown, wherein each ridge of the plurality of ridges includes:
a base positioned directly adjacent to the crown;
a top surface opposite the base of the ridge;
a ridge apex defined as a maximum height of the ridge measured in a direction perpendicular from the base of the ridge;
a front surface comprises a first end closest to the face portion and a second end closest to the ridge apex; and
a rear surface defining a portion of the ridge being closest to the rear portion of the golf club head, extending from behind the ridge apex towards the rear portion of the club head;

wherein:
the front surface defines a portion of the ridge being closest to the face portion, extending from near the face portion towards the rear portion of the club head;
the turbulator is positioned in a forward one-third portion of the crown in a front end to a rear end direction; and
at least one of the front surface, the top surface, or the rear surface includes two angled planar surfaces.

12. The golf club head of claim 11 , wherein the front surface is angled from the loft plane, where the angle comprises a range from 87 degrees to 100 degrees.

13. The golf club head of claim 11 , wherein the ridge apex of each ridge of the plurality of ridges is positioned within the first 50% of the ridge length.

14. The golf club head of claim 11 , wherein each ridge of the plurality of ridges comprises: a pair of side walls extending from the base to the top surface, and wherein each side wall tapers towards the top surface at an angle of no less than 60 degrees.

15. The golf club head of claim 11 , wherein the top surface extending between the front surface and the rear surface, the top surface having a width extending in a direction from the heel end to the toe end of the club head.

16. The golf club head of claim 15 , wherein the base extends an entire length of the ridge in a direction from the front surface to the rear surface of the ridge; and
the base having a width extending in a direction from the heel end to the toe end of the club head, wherein the width of the top surface is at least 50-90% of the width of the base.

17. The golf club head of claim 11 , wherein the plurality of ridges is selected from the group consisting of: at least 3 ridges, at least 4 ridges, at least 5 ridges, and at least 6 ridges.

18. The golf club head of claim 11 , wherein the leading edge comprises a leading edge plane forming a leading edge angle with the loft plane, wherein the first end of the front surface of each ridge of the plurality of ridges being at least partly located between the leading edge plane and the rear portion, but not extending beyond the leading edge plane.

19. The golf club head of claim 18 , wherein the first end of the front surface is positioned on the leading edge.
