Abstract
Golf balls include dimples for generating a turbulent boundary layer. At least some of the dimples include a fan-shape. The fan-shaped dimple has a plurality of blades. Each blade has a trailing edge flush with a land area of a spherical surface of the golf ball, a leading edge, and a side wall connected to the leading edge. The dimple also has a sloped floor extending from the trailing edge to the leading edge, a blade tip connecting the leading edge to the trailing edge at a distal end of the blade, and a blade root connecting the leading edge to the trailing edge at a proximal end of the blade.
Claims13
A golf ball comprising a generally spherical surface and plurality of dimples separated by a land area formed on the surface, wherein at least one of the dimples comprises:
- a plurality of blades, wherein each blade comprises:
- a trailing edge flush with the land area of the golf ball;
- a leading edge;
- a side wall connected to the leading edge, wherein the height of the side wall varies along the leading edge, and wherein the height of the side wall is zero at each end of the side wall;
- a sloped floor extending from the trailing edge to the leading edge;
- a blade tip connecting the leading edge to the trailing edge at a distal end of the blade;
- and
- a blade root connecting the leading edge to the trailing edge at a proximal end of the blade.
A golf ball comprising a generally spherical surface and plurality of dimples separated by a land area formed on the surface, wherein at least one of the dimples comprises:
- a plurality of blades, wherein each blade comprises:
- a trailing edge flush with the land area of the golf ball;
- a leading edge;
- a side wall connected to the leading edge;
- a sloped floor extending from the trailing edge to the leading edge;
- a blade tip connecting the leading edge to the trailing edge at a distal end of the blade;
- and
- a blade root connecting the leading edge to the trailing edge at a proximal end of the blade,
- wherein the leading edge of one blade is connected to the trailing edge of an adjacent blade at a connection point and the side wall has a largest height at the connection point, and
- wherein the connection point is located between the ends of the leading edge and divides the leading edge into a first portion and a second portion.
A golf ball comprising a generally spherical surface and plurality of dimples separated by a land area formed on the surface, wherein at least one of the dimples comprises:
- a plurality of blades, wherein each blade comprises:
- a trailing edge flush with the land area of the golf ball;
- a leading edge;
- a side wall connected to the leading edge;
- a sloped floor extending from the trailing edge to the leading edge;
- a blade tip connecting the leading edge to the trailing edge at a distal end of the blade;
- and
- a blade root connecting the leading edge to the trailing edge at a proximal end of the blade, the blade root comprising an edge that extends from a base end of the trailing edge to a base end of the leading edge, wherein the blade root of one blade overlaps a portion of the leading edge of another blade.
