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. In some embodiments, the crown includes a lattice-like structure having thin regions surrounded by a web of relatively thicker regions. In some embodiments, the club head includes one or more stiffening tubes attached between the sole and the crown to improve the acoustic performance of the golf club head.

A high moment of inertia is enabled in a novel golf putter head in which also infinite adjustment of the lie angle and adjustment of total weight over a very wide range are enabled. The putter can be configured for either right-handed or left-handed players. The putter head has a cylindrical recess partially open through the top of the head and fully open to the rear of the head allowing the insertion of a cylindrical shaft receiver disc. The shaft can be of any allowed length and the lie angle can be from 26 degrees to 10 degrees from vertical. The mass properties of the putter head may be changed and adjusted by addition or removal of weights at the extreme toe and heel ends of the putter head.

A putter comprising an adjustable hosel structure is disclosed herein. In particular, the putter comprises a hosel assembly comprising a shaft receiver and two interlocked bars that connect the shaft receiver to the putter head. A plurality of bolts connect the bars to the shaft receiver and the putter head, and these points of connection are joints about which the bars move, and which can be restrained to immobilize the hosel assembly or otherwise reversibly fix it in place so that a longitudinal shaft axis is aligned with a desired portion of the putter head. The hosel assembly preferably is adjustable along a horizontal, heel-to-toe axis, and is partially disposed, and secured, within a pocket on the heel side of the putter head.

According to one aspect of the present invention there is provided an adjustable connector including at least two parts, each having a main body with a bore having a longitudinal axis therein, wherein an external surface of the main body of a first part is configured to bear against an internal surface of the bore of a second part when the first part is at least partially inserted into the bore of the second part to form a connection, characterized in that the positioning of the bores with respect to the main bodies is such that when the parts are connected to each other, rotation of one part with respect to the other changes the inclination of the longitudinal axes of the bores with respect to one another.

Golf club heads are releasably engaged with shafts so that the club heads and shafts can be readily interchanged and/or so that the shaft position with respect to the club head can be readily changed. Assemblies for connecting the club head and shaft may include: a shaft adapter, a collet, a ferrule, and a club head having an interior chamber. The club head and shaft may be changed by releasing the securing system and exchanging the original parts with different parts.

Embodiments of golf clubs with adjustable loft and lie and methods of manufacturing golf clubs with adjustable loft and lie are generally described herein. Other embodiments may be described and claimed.

In general, aspects of this invention relate to golf clubs or golf club components incorporating adjustment members that permit ready adjustability of golf club parameters and/or interchangeability of golf club components to change a golf club configuration, and methods for providing golf clubs. According to aspects of this invention, an adjustment member may be utilized to allow the adjustability of a golf club parameter to change a golf club configuration, while ensuring there is substantially no change to other club or club head variables, parameters or characteristics. According to another aspect of this invention, an adjustment member may be utilized to allow the adjustability of two golf club parameters independently to change a golf club configuration, while ensuring there is substantially no change to other club or club head variables, parameters or characteristics.
