  • Patent number: 12330027
    Abstract: A hollow golf club head includes a metallic front body coupled with a composite rear body. The front body includes a strike face and a surrounding frame that extends rearward from a perimeter of the strikeface. The rear body includes a crown member coupled with a sole member. The sole member has a structural layer formed from a filled thermoplastic material, while the resilient layer is bonded to the external surface of the structural layer and is formed from a fiber-reinforced thermoplastic composite material. The resilient layer has an opening through which a metallic weight pad at least partially extends. The weight pad is bonded to the structural layer and includes an aperture for attaching a metallic weight. The golf club head can also have one or more structural members that are upright and connect the weight pad to the crown member.

  • Patent number: 12296236
    Abstract: A mixed material golf club head including an outer metallic component and a polymeric component. The outer metallic component comprises the strike face. The polymeric component comprises a reaction wall that lies flush with a rear surface of the strike face. The reaction wall slidably translates across a back surface of the strike face at impact. In some embodiments, the outer metallic component is integrally formed with the crown and the polymeric component is integrally formed with the sole, to allow dynamic delofting for low-handicap golfers. In other embodiments, the outer metallic component is integrally formed with the sole and the polymeric component is integrally formed with the crown, to allow dynamic lofting for high-handicap golfers.

  • Publication number: 20250128122
    Abstract: A system includes a processor configured for leveraging reference ball flight data associated with an individual and a reference club having a reference loft angle to compute predicted ball flight characteristics for other candidate golf clubs having loft angles different from the reference loft angle. The predicted ball flight characteristics include predicted distances of golf shots the individual is expected to make using the candidate golf clubs that can further accommodate a computed recommendation of optimal loft angles for a consistently gapped golf club set.

  • Publication number: 20240335710
    Abstract: Described herein is a tour iron having a golf club head with a faceplate, a body, and an insert. A sole, top rail, rear, and the faceplate enclose a cavity within the body. The cavity can house the insert. The insert can comprise a low-density material, allowing weight to be concentrated around the peripheral edge of the golf club head. The rear of the golf club head has an inflection seam running from the heel to the toe. The golf club head has an upper portion, above the inflection seam and a lower portion below the inflection seam. The lower portion can have a depth greater that the upper portion depth. The faceplate, body, and insert can be formed of different materials having different densities. The golf club head has a comparatively high moment of inertia and a low center of gravity. Other embodiments and methods are described herein.
