摘要:
A golf club with a golf club head formed of two distinct parts is presented. The club head includes a lower, ball striking member configured to contact a golf ball. The club head further includes an upper member, connected to the ball striking member at a top surface of the ball striking member. The ball striking member may be formed of a more dense material than the upper portion, thereby lowering the center of gravity of the club to provide improved performance characteristics.

A golf club or component thereof has a surface, wherein at least one area of the surface has a level of hydrophilicity which is less than the level of hydrophilicity in at least one surrounding portion, causing moisture to be preferentially attracted to the surrounding portion. In one aspect, the surface is a striking face and the surrounding portion is one or more grooves formed in the striking face. In another aspect, the surface is a grip and the surrounding portion is one or more channels formed in the grip. In some examples, hydrophobic or superhydrophobic surfaces on golf club components repel water and, in some instances, also offer self-cleaning functionality.

Golf clubs, club heads, and club weighting systems may include: (a) a club head body member; and (b) one or more weight members movably engaged with the club head body member so as to move between a first position and a second position to change an overall exterior shape of the club head. This shape change may result in changes to the overall center of gravity, weighting, and/or moment of inertia characteristics of the club head. Alternatively or additionally, the weight member(s) may be removed from the club head body member, reoriented, and/or replaced with a different weight member, e.g., to change the overall exterior shape, center of gravity, weighting, and/or moment of inertia characteristics of the club head. Methods of making and using these clubs, club heads, and weighting systems also are described.

Wood-type golf club heads include: (a) a club head body including heel, toe, crown, sole, and weighted rear portions; and (b) a variable thickness ball striking face. The club head body parts and weighted portion(s) may be arranged such that the club head has a moment of inertia about a vertical axis passing through the club head center of gravity of at least 5000 g-cm2. Such club heads may include: (a) a cup face member including a ball striking face portion and a return portion; (b) sole and crown portions engaged with the return portion; (c) a rear body member engaged with the crown and/or sole portions; (d) a weight member at the club head rear; and/or (e) a hosel member engaged with the cup face member, the crown portion, and/or the sole portion.

A golf club head system and a golf club head for inclusion into a golf club are provided. The golf club head system includes two or more rear or secondary body members, each configured for interchangeable attachment to a front or main body member. Each rear body member may have a different external shape, and each rear body member may have a different combination of center-of-gravity and moment-of-inertia characteristics. The system further includes a detachable attachment element for interchangeably and detachably attaching the rear body members to the front body member. The system may further include the front body member, wherein the front body member has a striking surface.

Putters and putter heads better camouflage the main body of the head and/or highlight the alignment aid. The top surface of the head (when viewed from a ball address orientation) may be finished in a non-reflective, matte finish, optionally, in a dark color and/or in a color or colors selected so as to blend into or match the color of a golf green. At least some portion of the shaft member may be colored and finished in this same manner. These features help in visualization of the alignment aid (which also may be designed to help in alignment). If desired, the club head and/or shaft color and finish may be customized based on the greens at a specific golf course, greens in a specific geographical region, greens of a specific grass type, greens at a specific time of year or under specific conditions, etc.

A golf club head is disclosed that includes weight positioning system for modifying a position of a center of gravity of the golf club head. The weight positioning system includes a weight and a support. The weight is independently movable along the support to change the position of the center of gravity in a first direction, and the weight is independently movable around the support to change the position of the center of gravity in a second direction.

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) a cylindrical structure having a cylindrical interior chamber for receiving a golf club shaft, a rotation-inhibiting structure, and a securing structure; and (b) a securing system for releasably engaging the securing structure. The club head and shaft may be changed by releasing the securing system and exchanging the original parts with different parts. Furthermore, the shaft may be bent or otherwise extend at an angle from the shaft connection assembly so as to allow adjustment of the shaft position with respect to the club head.
