Abstract: A golf putter head assembly includes a putter head and a two-part hosel detachably mounted to the putter head by a single removable fastener. The two-part hosel includes a lower intermediate connector extending upwardly from the putter head, and an upper shaft connector extending upwardly from the intermediate connector. The fastener extends through a crown-to-sole through-bore formed in the putter head, through a longitudinal through-bore formed in the intermediate connector, and into a blind bore formed in a lower member of the shaft connector. An upper member of the shaft connector is mountable to a putter shaft. The upper member is angled relative to the lower member to define a shaft-head lie angle, and is offset from the lower member to define a shaft-head offset distance. The intermediate connector has a selected length that establishes a shaft-head balance characteristic. A kit and a method are also disclosed.

Abstract: A flexible grip for a golf club having a tubular member with one or more strips of elastomeric material significantly softer than the elastomeric material of the tubular member provided on the exterior surface of the tubular member. In one version, the strips are on the top flat surface, on other versions, the strips are on the side or both. In another version, an air pocket is provided beneath the strip on the top surface. In another version, a rib or key on a core bar forms a channel on the inner surface of the tubular member during molding. Upon removal of the core bar, a pocket is formed along the grip upon assembly on a club shaft. Upon gripping, the strips and pockets allow depression providing indication of grip pressure. The strips also provide visual aids for user hand positioning.

Abstract: Embodiments of golf club heads comprising a nanocomposite to attenuate sound of the club head are described herein. The nanocomposite comprises graphene and a polymer. The graphene can be in the form of a powder, where the graphene is suspended within the polymer. The nanocomposite can be disposed within an interior surface of the club head. The nanocomposite can be applied to selected portions of the club head such as behind the strike face. The nanocomposite comprising graphene and the polymer can provide an alternative filler material over homogenous materials to attenuate the sound to provide a pleasing sound and feel to a golfer.

Abstract: Unlike earlier visual alignment aids, the present devices and methods may transfer focus away from a central sight line to a plurality of multicolored auxiliary sight lines. The multicolored sight lines are typically brightly colored to maintain the player's focus and help avoid head movement during initiation of the swing. Further, in some embodiments, the central and/or auxiliary sight lines are dashed, with the dashes either aligned or offset from one another. In this way, hyper-acuity becomes two-dimensional with sight lines running in a first dimension (e.g., from face-to-back, when markings are on the crown, or top-to-bottom, when markings are on the face) and cross lines, made up of inter-sight line dashes, running in a second dimension (e.g., from heal-to-toe).

Abstract: A golf club includes a golf club head, a shaft adapter secured within a hosel of the golf club head, and a shaft secured within the shaft adapter. The golf club shaft is formed from a fiber reinforced polymer and extends along a longitudinal axis between a tip end and a grip end. The golf club shaft includes a tip end section, a grip end section, and a tapered section between the tip end section and the grip end section. The tapered section of the shaft includes a reference portion within the upper half that has a frustoconical shape with a near-constant taper rate, and a narrowed portion within the lower half. The narrowed portion is recessed relative to a reference surface extrapolated from the frustoconical shape.

Abstract: A specialized tool for golfers, this invention is small enough to fit comfortably in a pocket, in the form of a ball marker, with a line long enough to be useful, and a custom-molded hook/clasp to hold it together neatly. In addition to being a ball marker, this unique combination of features provides the user the length, accuracy, and speed-of-use necessary for: determining which ball is closest to (or farthest from) the hole, whether a ball is in or out of bounds, and a thin, straight line for putting practice; without unduly delaying the pace of play on the golf course.

The shaft-mount has a first threaded coupling member and a bore that is sized to securely receive the golf club shaft. The head-mount has a second threaded coupling member. The head-mount is sized to be securely received within the bore of the hosel of the golf club head. The first threaded coupling member of the shaft-mount mates with the second threaded coupling member of the head-mount to form a releasable connection of the golf club shaft and the golf club head. The first threaded coupling member of the shaft-mount has dual-handed-thread ability which allows the releasable connection to follow left-handed-thread convention and right-hand-thread convention.

Abstract: Embodiments of golf club heads comprising a face with a variable thickness to improve the durability in the club head, increase ball speed, and increase characteristic time (CT) are described herein. The face comprises thickened and thinned regions. The face includes a perimeter thickened region positioned near a perimeter of the face, a thinned region positioned inward of the perimeter thickened region toward a center of the face, and a central thickened region positioned over the center of the face. The combination of the thickened and thinned regions of the face increase ball speed and further increase or maximize CT without sacrificing durability.
