Abstract:
The present invention is directed towards the novel use of thermoplastic materials to form center core shells for use in liquid filled golf balls. Wound golf balls of the present invention which employ liquid filled centers formed from thermoplastic materials exhibit the same or superior in-play characteristics such as initial velocity as compared to conventional wound golf balls.
Abstract:
The invention includes a golf ball having a substantially spherical inner core (100), a first wound layer (105) of high tensile elastic modulus fibers wound about the inner core (100), and a second molded layer (110) of a polymeric material surrounding the wound layer (105), as well as a method of making a golf ball, including providing an inner core (100) winding a high elastic modulus fiber on the inner core (100) to create a first wound layer (105), and molding an outer layer (110) of polymeric material about the first wound layer (105). The inner core (100) in the above method and apparatus may be made of solid resilient materials or a center (115) wound with a low modulus fiber (120) and provided with an initial tension.
Abstract:
This invention relates to an improved golf ball center (206) having a substantially spherical portion (208), and a plurality of protrusions (210) extending outwardly from the spherical portion (208), the ends of which support the center (206) when it is placed in a spherical mold (240), and to a mold (240) for injection molding such a golf ball center having first and second mold halves (242, 244), and for a method of molding a golf ball core by placing a golf ball center (206) into a spherical mold cavity (246) wherein the golf ball center (206) is supported by the protrusions (210), and filling between the mold cavity (246) and the center (206).
Abstract:
An improved golf shoe (10) which incorporates a spike socket spine frame system (50) that extends throughout the shoe sole for receiving all of the spike receptacles and is embedded in the outsole. The spine frame (50) provides improved shoe performance and spike location and is made of a material that is stiffer than the outsole material. More particularly, the shoe sole is comprised of a spike socket spine having seventeen spike socket locations (40): three spike sockets in the toe section (40a-40c), six spike sockets in the metatarsal section (40d-40i), four spike sockets in the shank section (40j-40m) and four spike sockets in the heel section (40n-40q), for receiving the posts (42) of the golf spikes.
Abstract:
This invention is a golf ball (10) having dimples (12) which have a constant depth (dde). The bottom (12b) of each dimple is substantially the same size as the dimple opening defined by perimeter (12p). The golf ball (10) has a spherical outer surface (11) which is connected to the bottom (12b) of each dimple (12) through wall (12w), which is substantially perpendicular to the dimple bottom (12b), and the outer spherical surface (11) of the golf ball (10).
Abstract:
A plurality of two or more golf clubs with improved weighting characteristics s is disclosed. More specifically, the present invention discloses s specific relationship between the mass M club of the golf club and the length L club to help improve the performance of the golf club.
Abstract:
A process for forming a golf ball cover composition, which process comprises: a) forming a polymer comprising (1) a first monomeric component comprising an olefinic monomer having from 2 to 8 carbon atoms; (2) a second monomeric component comprising an unsaturated carboxylic acid based acrylate class ester having from 4 to 22 carbon atoms; and (3) an optional third monomeric component comprising at least one monomer selected from the group consisting of carbon monoxide, sulfur dioxide, an anhydride monomer, an unsaturated monocarboxylic acid, an olefin having from 2 to 8 carbon atoms, and a vinyl ester or vinyl ether of an alkyl acid having from 4 to 21 carbon atoms; b) applying a sufficient amount of heat to the polymer to convert it to a substantially molten state; c) adding an inorganic metal base to the molten polymer to form a mixture; and d) saponifying the mixture to form a polymer salt particularly adapted for forming improved golf ball covers.
Abstract:
The present invention is directed towards a multilayer golf ball which comprises a core (2) with one or more layers; at least one cover layer (3); and one or more mantle layers (4) disposed between the core and cover layer, wherein the mantle layer comprises thermoplastic polyetherester, thermoplastic polyester, dynamically vulcanized thermoplastic elastomer, functionalized styrene-butadiene elastomer, thermoplastic polyurethane, metallocene polymer or blends thereof and thermoset materials.
