Sighting aids for golf balls that allow a golfer to sight a direction in which to hit or putt a golf ball and a method of producing the same and golf balls having sighting aids that have a certain degree of wrap determined by a sighting equation and surface coverage determine by a surface coverage equation.

Golf balls having sighting aid and methods of making same

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.

Fan-shaped golf ball dimple

The present invention relates to golf balls, specifically to a golf ball comprising an aerodynamic pattern having novel shaped dimple structures which reduce the variation in airflow turning angle thereby improving the golf ball's flight performance. The dimple structures have a conical shaped base with a dimple in the center and reduced or no flat land areas between the dimples.

Golf ball aerodynamic configuration

The present invention is directed to golf balls having a diameter of greater than 1.68 inches and including at least one layer formed from an HNP composition.

Golf ball

The present invention concerns golf balls having a modified aerodynamic configuration and a method for creating a modified aerodynamic configuration that improves dimple coverage, interdigitation, and non-alignment in golf ball dimple patterns by rotating the repeating area elements about pre-determined center points, with further optional steps of expanding or contracting the elemental arrangements about pre-determined center points, enlarging or reducing the sizes of dimples, and adding extra dimples to occupy land areas created by the previous steps. The resulting modified aerodynamic configuration with a rotated element has increased dimple coverage, greater interdigitation and improved non-alignment.

Large diameter golf balls having a foam core are provided.

Golf balls having a foam center

A golf ball dimple having a plurality of arms wherein each arm includes a leading edge, a trailing edge, side walls, and a sloped floor. The dimples of the invention may be included in a dimple pattern that may also include other types of dimples.

Multi-arm dimple and dimple patterns including same

A golf ball having an improved surface pattern is disclosed. The golf ball has one or more channels on its surface. The channels form spherical polygonal tiles that may include a plurality of dimples. These dimples may be circular or polygonal in shape.

Golf ball surface patterns comprising a channel system

Golf balls including at least one modified dimple group are disclosed. The modified dimple group comprises one or more modified dimples forming an axially symmetric pattern about a Correction Area Centroid located on an axis of symmetry at a latitude greater than 0&#xb0;, where 0&#xb0; represents the hemispherical pole and 90&#xb0; represents the equator. The modified dimples can be altered, for example, by changing dimple coverage, dimple diameter, dimple depth, dimple edge angle, dimple volume, dimple cross-sectional shape, and/or dimple plan shape. Such modifications preferably produce a golf ball that flies more consistently regardless of orientation when struck than a corresponding golf ball without such modifications.

A golf ball is provided that has improved aerodynamic efficiency, resulting in increased flight distance for golfers of all swing speeds, and more particularly for golfers possessing very high swing speeds, such as those who can launch the balls at an initial speed greater than 160 miles per hour and more particularly at initial ball speed of about 170 miles per hour or higher. The golf ball of the present invention combines lower dimple count with multiple dimple sizes to provide higher dimple coverage and improved aerodynamic characteristics.

Golf ball with improved flight performance

A golf ball having an improved surface pattern is disclosed. The golf ball has one or more bands on its surface. These bands may be either channels or raised beads. The bands have variable widths and/or heights/depths, either within the same band or between bands. These bands may decrease drag, or may increase lift. These bands may be linear, or may be curved, and may or may not fully circumscribe the golf ball. These channels or ridges may also be combined with traditional or non-traditional dimples.

Golf ball surface patterns comprising variable width/depth multiple channels

A golf ball mold having a non-planar parting surface formed by superimposing a base waveform with a least one shorter secondary waveform. The base waveform is defined by a series of concentric arcs wherein adjacent arcs are connected with a straight line segment that is tangent to the arcs and creates an acute angle. The length of the straight line segment being critical to the accuracy and predictability of the parting line.

Mold for a golf ball

The present invention concerns a golf ball having dimple groupings comprised of multiple angular spiral shaped arms that are arrayed to form polygonal perimeters, wherein the number of arms equals the number of perimeter sides. This allows greater symmetry about the dimple grouping center, thereby improving the consistency of the aerodynamic performance of the ball. In another unique feature of the present invention, the angular shape of the arms facilitates the formation of polygonal shaped dimple groupings, which can fit closely together to cover a greater proportion of the ball's surface, preferably more than about 85% surface coverage, thereby further enhancing aerodynamic performance.
