Golf ball with spherical polygonal dimples
View Patent ↗A golf ball includes an outer spherical surface and a plurality of dimples formed thereon. In accordance to one aspect of the invention, the dimples in accordance to the invention have a polygonal perimeter and a substantially spherical, concave depression. The substantially spherical depression comprises a spherical depression and a transitional portion bridging the area between the polygonal perimeter and the spherical depression. In accordance to another aspect of the invention, one or more sides of the polygonal perimeter may be non-linear or curved. The dimples of the present invention may fill the ball's entire outer surface, or the dimples may occupy a predetermined pattern on the ball. The predetermined pattern may also include one or more channels or raised beads on the surface of the ball.
1. A golf ball comprising:
a substantially spherical outer surface, and
a plurality of first dimples formed on the outer surface of the ball, wherein the perimeter of the first dimples comprises a regular polygon, and defines a concave, substantially spherical portion; and
wherein the spherical portion of the first dimples is defined by a curved enclosure, said curved enclosure contacts all the sides of the regular polygonal perimeter.
2. The golf ball of claim 1 , wherein the curved enclosure is a circle.
3. The golf ball of claim 1 , wherein a transitional surface area is located between the perimeter of the dimple and the curved enclosure.
4. The golf ball of claim 3 , wherein the transitional surface area is substantially a flat surface.
5. The golf ball of claim 3 , wherein the transitional surface area is a curved surface.
6. The golf ball of claim 5 , wherein the curved surface is conical.
7. The golf ball of claim 5 , wherein the curved surface is cylindrical.
8. The golf ball of claim 5 , wherein the curved surface is spherical.
9. The golf ball of claim 5 , wherein the curved surface is parabolic.
10. The golf ball of claim 1 , wherein the center of the curved enclosure and the center of the perimeter are located proximate to each other.
11. The golf ball of claim 10 , wherein the center of the curved enclosure and the center of the perimeter coincide with each other.
12. The golf ball of claim 1 , wherein the center of the curved enclosure and the center of the perimeter are offset from each other.
13. A golf ball comprising:
a substantially spherical outer surface, and
a plurality of first dimples formed on the outer surface of the ball, wherein the perimeter of the first dimples comprises at least one linear edge and at least one curved edge, and defines a concave, substantially spherical portion; and
wherein the spherical portion of the first dimples is defined by a curved enclosure and said curved enclosure contacts the perimeter at least at one location.
14. The golf ball of claim 13 , wherein the curved enclosure is a circle.
15. The golf ball of claim 13 , wherein the curved enclosure is an oval.
16. A golf ball comprising:
a substantially spherical outer surface, and
a plurality of first dimples formed on the outer surface of the ball, wherein the perimeter of the first dimples comprises at least one linear edge and at least one curved edge, and defines a concave, substantially spherical portion; and
wherein the spherical portion of the first dimples is defined by a curved enclosure and said curved enclosure is contained within the perimeter of the dimples.
17. The golf ball of claim 16 , wherein the curved enclosure is a circle.
18. The golf ball of claim 16 , wherein the curved enclosure is an oval.
