  • Patent number: 11135614
    Abstract: Methods of applying a polymeric coating to a rear face surface of golf club heads with variable face thickness are disclosed herein. The coating, which preferably comprises polyurea, improves the durability of the face and reduces the hits to failure ratio of the golf club head. The coating improves the performance of the golf club head because it allows for reduction in overall face thickness and easy post-process manipulation to allow for fine-tuning of mass properties after production. The reduction in thickness leads to overall weight reduction, because the polymer is roughly a quarter of the density of titanium or stainless steel, and also reinforces the face, thereby increasing the lifespan of the club.

  • Patent number: 11130029
    Abstract: A golf club head, preferably a putter head, comprising at least one structural support member is disclosed herein. The structural support member has a smooth, organic-looking aesthetic, with a continuously changing curvature along its spline and at least one surface, and preferably connects one portion of the golf club head to another portion. Where the support member connects to other portions of the golf club head, the surfaces of the member have a curvature that changes smoothly and continuously, lacking any sharp corners.

  • Patent number: 11123612
    Abstract: The use of a low molecular weight farnesene, poly(farnesene), and farnesene copolymer in a golf ball is disclosed herein. In a core, low molecular weight farnesene, poly(farnesene) or farnesene copolymer is blended with 1,4 polybutadiene or a polyalkenamer. In a mantle layer, low molecular weight farnesene, poly(farnesene), and/or farnesene copolymer can be blended with non- or partially neutralized copolymeric or terpolymeric ionomer(s). In a cover, low molecular weight farnesene, poly(farnesene), and farnesene copolymer can be blended with highly neutralized ionomer.

  • Patent number: 11097166
    Abstract: A process for manufacturing a putter with a bi-material shaft is disclosed herein. The putter comprises a putter head, the bi-material shaft, a mass member and a grip. The bi-material shaft comprises a body with a tip end and a butt end. The body comprises a metal section extending from the tip end to a connection point, and a composite section extending from the butt end to the connection point. The mass member is positioned within an opening at the butt end of the shaft. Mass from the shaft is transferred to the club head and the mass member in the butt end of the shaft.

  • Patent number: 11090531
    Abstract: A golf club head having an adjustable hosel assembly and a plug assembly that can reversibly secure the hosel assembly in a chosen configuration within the club head is disclosed herein. In particular, the hosel assembly includes a shaft sleeve that is trapped within a hosel opening with a screw that extends through an interior flange. The plug assembly includes a wedge-shaped flange that is inserted into an opening in the body and fits between the interior flange and the head of the screw to temporarily immobilize the shaft sleeve. The plug assembly preferably completely fills the opening in the body so as to preserve a smooth outer mold line of the club head and allow graphics or decorations to extend across the exterior surface without disruption.

  • Patent number: 11083937
    Abstract: A method of manufacturing a golf club head with a plurality of stiffening members proximate the face, and particularly solid rods or a plate with one or more cutouts, is disclosed herein. The method includes the steps of preparing a wax of a golf club head body having at least one through-hole, a hollow interior, and at least one receiving pocket, preparing waxes of one or more stiffening members, inserting the wax of the stiffening members into the through-hole and seating its opposite end in the receiving pocket, bonding each of the stiffening members to the body with an adhesive material to form a combined wax mold, and casting a golf club head from the combined wax mold.

  • Patent number: 11083939
    Abstract: A golf club head with an adjustable weight assembly that includes a pair of stacked, rotatable circular plates with through-slots and a slidable weight that can move within the slots and clamp the plates together so that they are reversibly fixed to a body portion is disclosed herein. The plates are preferably composed of a lightweight material such as composite, and are located on the sole so that the weight assembly is visible to a user. The plate and slidable weight combination and allows for an increased range of personal performance customization by way of adjustability and interchangeability without using up available discretionary mass in the golf club head.

  • Patent number: 11065512
    Abstract: A golf club head comprising a body with a heel-side sole opening in communication with a hosel bore, a removable shaft sleeve with a tip sized to fit within the hosel bore, and a weight plug sized to fit within, and at least partially fill, the heel-side opening is disclosed herein. The weight plug, which has a base end with a through-opening, a tip end with a flange, and a side opening in communication with the through-opening, is connected to the shaft sleeve with a screw. When the golf club head is fully assembled, a hosel flange is trapped between the weight plug and the tip end of the shaft sleeve, and tightening the screw causes the weight plug and the shaft sleeve to move towards one another.
