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. The support member may be part of a lattice structure formed via binder jetting.

Embodiments of golf coupling mechanisms are presented herein. Other examples and related methods are also disclosed herein.

Methods of creating golf club components with complex structures that would be difficult, impossible, or cost prohibitive to produce, such as lattice structures, beam structures, and complex surface-based structures, are described herein. In particular, a binder jet machine is used create complex structures to optimize weighting, sound, and performance of golf club heads. The method preferably includes the steps of designing a golf club head component in CAD using optimization software, printing the component from a powdered material, and then removing excess powder from the component via port holes that extend into an external surface of the component and communicate with interior voids within the component.

An iron-type golf club head where a ratio of a maximum toe height of the iron-type golf club head to a blade length of the iron-type golf club head is greater than zero and at most 0.62. A maximum thickness of the front portion, along the strike face, corresponds with a location toeward of a geometric center of the strike face. The thickness of the front portion, at the geometric center of the strike face, is less than the maximum thickness of the front portion. A coefficient of restitution (COR) of the iron-type golf club head is at least 0.818 and at most 0.830. An entirety of the sole is rounded along a plane parallel to the strike face, and a radius of curvature of the sole, along the plane parallel to the strike face, is no more than between, and inclusive of, 100 mm and 275 mm.

A golf club head is described having a body defining an interior cavity and comprising a heel portion, a toe portion, and a sole portion positioned at a bottom portion of the golf club head, and a crown positioned at a top portion. The body has a forward portion and a rearward portion. A face is positioned at the forward portion of the body. The face has a center face location and includes a center face characteristic time. An off-center location on the face is located at about −40 mm in a heel direction away from the center face location. The off-center location has an off-center characteristic time of at least 80% of the center face characteristic time.

Described are embodiments of golf club heads having an internal cavity and features that cause the golf club head to have an improved acoustic performance when striking a golf ball. Some embodiments include one or more weight tracks and/or weight ports formed in the sole for receiving adjustable weights. The golf club heads can include one or more internal ribs, thickened wall regions, and/or posts positioned within the cavity that increase the rigidity of the club head and improve the acoustic performance of the club head when striking a ball.

A golf club head comprising two components, wherein the first component comprise a ball striking surface, a striking face return, and a sole extension with a rear mass. And wherein the second component comprises a lower density material, comprising part of the crown and part of the sole. The first component comprises a majority of the mass of the golf club head, having a rear mass comprising 20% to 35% of the mass of the golf club head.

A golf club head includes a body defining an interior cavity. The body includes a sole positioned at a bottom portion of the golf club head, a crown positioned at a top portion, and a skirt positioned around a periphery between the sole and crown. The body has a forward portion and a rearward portion. The club head includes a face positioned at the forward portion of the body. The face defines a striking surface having an ideal impact location at a golf club head origin. Embodiments include club heads for a fairway wood that at least one of a high moment of inertia, a low center-of-gravity, a thin crown and a high coefficient of restitution. A sleeve for easily disconnecting a shaft to the club head allows for selective adjustment of the head's loft and lie angle.

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. The support member may be part of a lattice structure formed via binder jetting.

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.
