A golf club has an offset shank between its shaft and its head. The offset shank has an arcuate reinforcing rib interconnecting intermediate and lower legs of the shank and extending to the head. This prevents the various legs of the shank from bending. The shaft is inclined rearwardly at a small angle to position the handle or grip above the head while the shaft is aligned with a golf ball when at rest.

A golf putter for putting a golf ball includes a clubhead having a ball-striking surface, a neck member, and a straight shaft having a grip portion at its proximal end and connecting to the neck member at its distal end. The neck member provides the connecting link between the distal end of the shaft and the top surface of the clubhead and includes a wedge-shaped portion which extends forward of the ball-striking surface. The wedge-shaped portion is segmented into an upper reduced-thickness sect...

A golf ball has alternating rough and smooth bands formed in its outer surface and the rough bands are aligned parallel to the ground when the ball is teed up. The rough bands are formed to completely trip the boundary layer of air flow around the ball in order to generate forces which counteract the forces generated by the smooth bands when the golf ball rotates about certain axes of rotation so as to control the path of the golf ball during its flight. The rough bands are formed in a plurality...

A golf ball is shown with an outer surface that is substantially covered with a plurality of spaced dimples that give the ball a suitable long and predictable flight pattern for wood or iron shots due to imparting an increased lift to the ball when the ball has a backspin. An undimpled patch is formed on the outer surface for use as a smooth putter-contacting surface. The size of the undimpled patch is chosen to achieve the desired putting accuracy objective without detracting from the increased...

A golf bag is provided of which members constituting the bag are separable and can be assembled with fastening members.

The invention comprises a set of golf clubs designed to suit a particular swing, each golf cluf of the set having an effective length and a total weight, wherein the product of the effective length and total weight is substantially the same for each club in the set, and wherein the clubs of the set each have a shaft incorporating a stiffness factor differing from club to club and functionally related to the speed of the swing of the club. The invention also includes the method and apparatus for ...

A golf club has an air flow hole through its head and the hole contains a whistle so that when the club is swung, the sound of the whistle provides an indication of the smoothness and velocity of the swing. The ambient air becomes locally turbulent at the hole's outlet end when the head swings. A tailpipe extends from the hole's outlet to a position where the ambient air is relatively free from such turbulence. The club head may include two whistles. The first whistle is actuated by air entering...

A golf ball having a thread-wound core and a cover formed of a block copolyetherester comprising (A) a terephthalic acid unit, (B) a 1,4-butanediol unit, (C) a unit of a dicarboxylic acid, other than terephthalic acid, or a short-chain diol, other than 1,4-butanediol, having a number-average molecular weight of not more than 300 and (D) a poly(alkylene oxide)glycol unit having a number-average molecular weight of from 500 to 3000. Said golf ball exhibits excellent impact resilience and also exhi...

Golf balls are provided having a thermoplastic polyesterurethane cover comprising the reaction product of a polyester having a molecular weight from about 800 to 1500 reacted with para-phenylene diisocyanate or 1,4-cyclohexane diisocyanate, which is thereafter molded around a golf ball core.

A golf club, particularly a putter, has a unitary body including forward and rearward generally triangular and approximately planar panels merging at their apices with an upright socket adapted to receive a club shank. At their intermediate portions the forward and rearward panels are spaced apart, and at their bases the panels merge with the forward and rearward transverse margins of a ground panel substantially square in plan in a plane normal to the socket axis. The upper face of the ground p...
