  • Publication number: 20100173728
    Abstract: A multi-lobed golf ball dimple is provided. The dimple comprises a plurality of lobes positioned radially around the center of the dimple, wherein each lobe is defined by a circumferential segment and may be further defined by spoke-like ridges. Each lobe comprises a first curved profile extending from the circumferential segment toward the center of the dimple and the first curved profile of each lobe abuts each other in an uninterrupted manner. The multi-lobed dimple may include uniform and non-uniform dimples. The curvature of the circumferential segments can be defined by a ratio of an inside radius to an outside radius. Each dimple also includes a slightly convex floor that is continuous and smooth. The curvature may match that of the outer surface of the golf ball. Further, a sloped wall interrupted by spoke-like ridges may connect the convex floor with the outer surface of the golf ball.

  • Publication number: 20100081519
    Abstract: A golf ball having an outside surface with a plurality of dimples formed thereon. The dimples on the ball have a cross-sectional profiles formed by a catenary curve. Combinations of varying dimple diameters, shape factors, and chordal depths in the catenary curve are used to vary the ball flight performance according to ball spin characteristics, player swing speed, as well as satisfy specific aerodynamic magnitude and direction criteria.

  • Publication number: 20100069176
    Abstract: 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.

  • Patent number: 7635312
    Abstract: The present invention is directed to multi-layer golf balls having a center, a cover layer, and at least one intermediate layer between the core and the cover layer. The core, the at least one intermediate layer and the cover are constructed to have different initial velocities and COR such that the gradient of the initial velocities and COR progress from a faster center to a slower cover.

  • Patent number: 7618333
    Abstract: A golf ball that is formed by a mold developed from a computerized modeling system such as CAD or CAE in combination with a CNC machine tool which superimposes a short waveform, or multiple waveforms, onto a longer base waveform to create a non-planar parting line that is functionally dependent on the underlying dimple geometry. The non-planar parting line is comprised of a plurality of peaks and valleys that are offset from the dimple perimeters, as not to bisect any dimple edge. Also, dimples on one side of the parting line interdigitate with dimples on the other side to form a more uniform distribution of dimples over the entire golf ball surface. Still further, the non-planar parting line has a amplitude which is less than 0.02 inch from an axis substantially coincident with the equator of the ball and the length of the parting line is less than 110 percent of the length of a curve defined by the circumference of the equator.

  • Patent number: 7607996
    Abstract: A golf ball is provided with a dimple pattern comprising two substantially identical elongated dimple pattern elements which fit together to form the complete dimple pattern. The dimple pattern can contain 344 dimples covering about 70.4% of the golf ball surface or 392 dimples covering about 73.3%, or other combinations of dimple count and coverage. The sizes of the dimples can be varied among either four distinct dimple sizes ranging from about 0.14 inches to about 0.17 inches or eight distinct dimple sizes ranging from about 0.11 inches to about 0.175 inches, or other dimple size combinations. The arrangement of dimples on the golf ball can be divided into a plurality of triangles having identical dimple arrangements with bilateral symmetry.

  • Patent number: 7601080
    Abstract: A golf ball includes a spherical outer surface and a plurality of dimples formed thereon. The dimples have an inner land surface with at least one spiral depression either disposed or superimposed on the inner land surface to energize or agitate the airflow over the dimpled surfaces to increase the aerodynamic performance of the golf ball. The spiral depression may turn clockwise or counterclockwise and can be either spaced apart, touching or overlapping each other. While the dimples may be circular, polygonal, triangular or elliptical, dimples having a cross section greater than 0.18 inch are preferred. The dimples may also comprise spiral depressions directly on the spherical surface of the ball.

  • Publication number: 20090186720
    Abstract: 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.

  • Publication number: 20090181805
    Abstract: 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.
