Golf ball with spherical polygonal dimples
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;
a first band disposed on the outer surface; and
at least one second band provided orthogonal to the first band,
wherein at least the first band comprises a first channel with a surface of the channel provided below the outer surface of the golf ball, and further comprises at least one convex feature in at least the first channel.
2. The golf ball of claim 1 , wherein the golf ball comprises an equator and the first band is disposed on the equator.
3. The golf ball of claim 1 , further comprising a hub at an intersection of at least the first and second bands.
4. The golf ball of claim 3 , further comprising at least a third band provided diagonally from the hub.
5. The golf ball of claim 1 , further comprising two or more dimples provided on the outer surface of the golf ball adjacent the bands.
6. The golf ball of claim 5 , wherein at least one of the dimples comprise a regular polygon and define a concave substantially spherical portion.
7. The golf ball of claim 6 , wherein the spherical portion is defined by a curved enclosure, the curved enclosure contacting all the sides of the regular polygonal perimeter.
8. The golf ball of claim 1 , wherein at least the first channel comprises a single channel.
