  • Patent number: 10213660
    Abstract: The invention provides golf club heads having aerodynamic features that disrupt air flow over the face when the club is swung. The features are milled into the face of the club head, including curved faces found in wood-type club heads. During a swing, the features cause the boundary layer to separate at a point closer to the rear of the club head during a swing, resulting in reduced drag. The invention also provides golf club heads with faces having a central region of symmetrical surface roughness. The symmetrical roughness in the central region of the face of wood-type club heads allows for shots with less spin and greater distance.

  • Patent number: 10213668
    Abstract: A shaft 6 includes a tip end Tp and a butt end Bt. If a shaft length is defined as Ls, a distance between the butt end Bt of the shaft and a center of gravity G of the shaft is defined as Lg, and a ratio of the distance Lg to the shaft length Ls is defined as a ratio of the center of gravity of the shaft, then the ratio of the center of gravity of the shaft is equal to or less than 47%. The shaft length Ls is equal to or less than 991 mm. If a forward flex is defined as F1 (mm) and a backward flex is defined as F2 (mm), a flex point ratio C1 of the shaft calculated by the following formula (1) is equal to or less than 39%: C1=[F2/(F1+F2)]×100]??(1).

  • Patent number: 10173116
    Abstract: A golf club comprises a shaft, a club head, and a connection assembly that allows the shaft to be easily disconnected from the club head. In particular embodiments, the connection assembly includes a removable hosel sleeve that allows a shaft to be supported a desired predetermined orientation relative to the club head. In this manner, the shaft loft and/or lie angle of the club can be adjusted without resorting to traditional bending of the shaft. In another embodiment, the club head has an adjustable sole that can be adjusted upwardly and downwardly relative to the strike face of the club head, which is effective to adjust the face angle of the club head.

  • Patent number: 10166449
    Abstract: A combined golf club cover and stand comprises a substantially rigid base and a cover portion configured to securely hold a head of a golf club against the substantially rigid base. The substantially rigid base includes a bottom platform, a first side wall, and an opposing second side wall with a bottom ledge that extends toward the first side wall, such that when the head of the golf club is held against the substantially rigid base, a toe end of the head is in contact with an interior surface of the first side wall, and a heel end of the head sits on the bottom ledge of the second side wall. The assembled golf club and combined golf club cover and stand is thus capable of standing upright, without any outside support, when the bottom platform is on a substantially flat underlying ground surface.
