摘要： The present invention provides a method for arranging dimples on a golf ball surface in which the dimples are arranged in a pattern derived from at least one irregular domain generated from a regular or non-regular polyhedron. The method includes choosing control points of a polyhedron, generating an irregular domain based on those control points, packing the irregular domain with dimples, and tessellating the irregular domain to cover the surface of the golf ball. The control points include the center of a polyhedral face, a vertex of the polyhedron, a midpoint or other point on an edge of the polyhedron and others. The method ensures that the symmetry of the underlying polyhedron is preserved while minimizing or eliminating great circles due to parting lines.

摘要： A golf ball 2 has a large number of dimples 10 on a surface thereof. The contours of the dimples 10 are non-circular. A standard deviation of areas of the dimples 10 is equal to or less than 1.7 mm2. A ratio of a total area of the dimples 10 relative to a surface area of a phantom sphere of the golf ball 2 is equal to or greater than 80%. By comparting lines CS obtained by projecting sides of a regular dodecahedron, which is inscribed in the phantom sphere, onto the phantom sphere, a surface of the phantom sphere can be divided into 12 units Ut each of which meets the following mathematical formula (I): −2≦(Nt/12)−Nu≦2 (I), where Nt represents the total number of the dimples 10 and Nu represents the number of the dimples 10 on one unit.

摘要： Multi-layered golf balls containing a two layered cover assembly are provided. In one embodiment, the cover assembly includes a relatively soft inner cover and relatively hard outer cover. Preferably, at least one of the cover layers is formed from a thermoplastic composition that preferably comprises: a) thermoplastic non-acid polymer, and b) plasticizer. A fatty acid ester such as ethyl oleate is preferably used as the plasticizer. Suitable non-acid polymers include, for example, polyesters, polyamides, polyolefins, and polyurethanes. The cover assembly has good impact durability and helps provide the ball with relatively high resiliency at given compressions.

摘要： An elastic solid ball structure of the present invention includes at least a thermoplastic polyurethane foam sphere center and a first adhesive layer, a first spherical lamina, a second adhesive layer, and a second spherical lamina sequentially disposed on the external surface of the thermoplastic polyurethane foam sphere center. The overall diameter of the elastic solid ball structure is 8 cm-26 cm. In addition, at least one protruding portion or at least one indentation portion is formed on the external surface of the thermoplastic polyurethane foam sphere center, thereby forming an irregular circular surface thereon. The described structural design provides the elastic solid ball structure of the present invention with advantages including good elasticity, a long serviceable life, permanently dispensing with the need to inflate, and eliminating having to re-inflate the ball structure.

摘要： Golf balls having a multi-layered core made of a foamed composition are provided. The core assembly preferably includes a foam inner core (center) and surrounding outer core layer. Preferably, a polyurethane foam composition is used to form the foam center. The core layers have different hardness gradients and specific gravity values. The foamed inner core assembly includes a geometric center, outer surface (skin), and thermal barrier layer that helps protect the foamed center region from the negative effects of high temperatures used during the ball-manufacturing process. Non-foamed thermoset materials such as polybutadiene rubber may be used to form the thermal barrier layer. The foam cores have good resiliency, thermal stability, and durability over a wide temperature range. The ball further includes a cover that may be multi-layered.
