  • Golf ball core with tailored hardness gradient
    Patent number: 11844983
    Abstract: Compositions including a hardness agent and golf ball cores made from such compositions having a tailored hardness gradient are disclosed. The type and concentration of the components in the composition, including the hardness agent, affects the hardness, hardness gradient, and compression of cores made from the composition and, thus, can be used to produce a golf ball having desirable performance characteristics.

  • GOLF BALLS HAVING CORES WITH INCREASED HARDNESS GRADIENT
    Publication number: 20230398412
    Abstract: Golf balls having cores with increased hardness gradients are provided. The cores have an increased “positive” hardness gradient (or a “hard-to-soft” hardness) where the outer surface of the core is harder than the center. The increased positive hardness gradient can be achieved by introducing a water-releasing agent into the core rubber formulation during the curing process. The resulting golf balls have reduced spin and sufficient impact durability.

  • FAIRWAY WOOD GOLF CLUB
    Publication number: 20230398415
    Abstract: A golf club head formed of an alloy of steel that is capable of improving the center of gravity (CG) location while maintaining traditional external dimensions of the golf club head. More specifically, the golf club head in accordance with the present invention achieves a relatively low CG while maintaining traditional external dimensions by reducing the amount of mass contributed by the crown, the striking face, and the hosel, and strategically reallocating this mass within and/or proximate the sole of the golf club head.

  • Multi-material golf club head
    Patent number: 11839797
    Abstract: A small-format metal wood golf club head may include a first portion including at least a striking face formed of an alloy of titanium and a second portion including at least a portion of a sole formed of an alloy of steel. The golf club head exhibits beneficial characteristics of both titanium and steel in that the titanium striking face is lighter than a steel striking face having the same coefficient of restitution (COR) and the steel sole allows for concentration of mass in a beneficial location within the golf club head, while overcoming traditional difficulties in bonding titanium and steel.

  • REGIONALLY TIME-DEPENDENT MIDSOLE
    Publication number: 20230389646
    Abstract: A golf shoe with a sole assembly having a regionally time-dependent midsole is provided. The midsole may include a lateral region constructed of a first material and a medial region constructed of a second material, where elastic properties of the lateral region and viscoelastic properties the medial region provide a neutral support platform when a relatively brief compression load is placed on the midsole (e.g., when a wearer is taking a step while walking), and further provide an everted supported platform when the compression load is placed on the midsole for a longer period of time (e.g., when the wearer is swinging a golf club).

  • Methods for applying polyurethane coatings to golf balls having a thermoplastic polyurethane cover
    Patent number: 11833395
    Abstract: Golf balls having covers made of thermoplastic polyurethane compositions are provided. Multi-piece golf balls can be made. Polyurethane primer coatings and polyurethane top-coatings are applied to the thermoplastic polyurethane cover. Different coating methods can be used. Isocyanate-rich and polyol-rich polyurethane coatings can be applied. In one embodiment, the golf ball can be treated with a multi-functional isocyanate prior to applying the coatings. The polyurethane cover composition and surface coatings can further include catalysts, ultraviolet (UV)—light stabilizers, and other additives. Heat is used to cure the coatings. The coating methods have many benefits and the finished balls have good physical properties.
