Golf club heads with cavities and inserts, and methods to manufacture golf club heads with cavities. Various embodiments include a golf club head comprising a body. The body comprises a strikeface at a front of the golf club head, a backface opposite the strikeface, a heel region, a toe region opposite the heel region, a sole, a rear portion at a rear of the golf club head, and a cavity located between the backface and the rear portion. In many embodiments, the body further comprises an insert within the cavity.

A grip (16) including a weight for a golf club is provided. The grip (16) includes an opening (33) with a first threaded portion (48). The weight includes a second threaded portion (62) configured to engage the first threaded portion (48) of the grip (16).
摘要:
The inventive fiber manufacturing process is particularly adapted for demanding applications such as sports racquets, including tennis racquets, badminton racquets and other sports applications The inventive fiber, for example graphite fiber) racquet frame is filled with a plastic foam and is formed using, for example, microencapsulation technology to time, generate and apply the pressure used to form the graphite composite matenal of which the racquet is composed This compares to the standard industry technique of air injection The racquet is thus not hollow like conventional graphite racquets, and the walls therefore can be made thinner than those of existing graphite racquets still being of the same strength or being stronger, which gives the racquet exceptional performance In addition, the overall dimensions of, for example the cross-section, of the racquet can also be reduced while still maintaining performance characteristics

A golf club head system and a golf club head for inclusion into a golf club are provided. The golf club head includes a main body member and a secondary body member. The main body member has a striking surface, a sole portion, a crown portion, and a rear face substantially opposed to the striking surface. The main body member defines an at least substantially enclosed main body cavity. The secondary body member is attached to the main body member and extends at least substantially over the entire rear face of the main body member. The golf club head system includes two or more secondary body members, each configured for interchangeable attachment to a main body member. Each secondary body member defines an internal concavity, has a different external shape, and has a different combination of center-of-gravity and moment-of-inertia characteristics.

A golf club head (42) having a non-traditional shape is disclosed. The golf club head (42) preferably has a volume ranging from 420 cubic centimeters to 470 cubic centimeters. The golf club head (42) preferably has a moment of inertia about the Izz axis through the center of gravity of the golf club head greater than 5000 grams- centimeters squared, and a moment of inertia about the Ixx axis through the center of gravity of the golf club head greater than 3000 grams- centimeters squared.
摘要:
Game apparatus, e.g., a game racquet or a golf club, with selectively variable and maintainable weight distribution, e.g. by moving material (e.g., liquid and/or solid weight members) within or on the apparatus and selectively positioning the weight (s) and maintaining weight position in or on the apparatus.

Golf club heads include: (a) a club head body having a ball striking face and defining a rear cavity; (b) a fluid-filled bladder in the cavity; and (c) a retaining member holding the fluid-filled bladder in the cavity. Other club heads include: (a) a club head body having a ball striking face and defining a rear cavity; and (b) an insert member in the rear cavity, wherein the insert member interior includes one or more chambers facing the rear surface of the ball striking face. The chamber(s) may cover at least 30% of a total surface area of the interior surface of the insert member and/or at least 30% of a total interior major surface area of the rear cavity. Golf clubs including these club heads and methods of making such golf clubs and golf club heads also are described.
摘要:
An adjustable heel and toe weighted putter head comprising of stand-alone heel and toe weight- carrying portions spaced rearward from the face portion for increased moment of inertia and also transversely spaced apart from each other by the width of a golf ball to therein define an alignment channel. Each weight-carrying portion consists of a through bore parallel to said face portion, a through threaded insert permanently secured in said bore, selectable weight members) housed in said insert, and end plug setscrews that book-end and removably secure said weight members) to therein provide for selectable total weight and longitudinal positioning of the center of gravity. The integration of the weight system and the alignment system provides for simultaneous tangential target alignment and parallax golfer head alignment. Positive sloped truncated conical projections on the putter face help minimize ball skid, maximize tactile properties, and provide enhanced audio feedback.
摘要:
A golf putter including a plurality of physical and visual aids for assisting the golfer to more consistently assume a good head and body position and to better putt a golf ball toward a remote hole. The putter head is engaged with one of a plurality of detachable flanges. The flanges all have different lengths, weights and shapes and are selectively engaged with the putter head to change its center of gravity and thereby change the characteristics of the putter. The golfer selectively engages the appropriate one of the plurality of flanges to give the putter head the type of characteristics that best suit his personal putting abilities and deficiencies and is thereby aided in correctly and accurately striking the golf ball. Each of the detachable flanges is provided with a first reflective surface and a second non-reflective surface. The reflective surfaces are all provided with a second linear marking thereon. The second linear marker is alignable with a first linear marking on the putter head and with the remote hole toward which the ball is to be putted. The reflective surface is used during practice sessions to aid the golfer in correctly positioning his head and body. The selected flange is removed and rotated during USGA sanctioned golf games to present the non-reflective surface on the upper side of the club. The different flanges are quickly and easily engaged with the putter head, so the golfer may change the nature of the putter for each hole they encounter on the golf course.
