摘要:
A golf club head includes a polymeric body and a metallic cup face that are coupled together through a plurality of mechanical fasteners. The cup face has a ball striking portion that defines a hitting surface and a side-wall that extends from a perimeter of the ball striking portion. The plurality of mechanical fasteners extend through the side-wall and operative to removably secure the face to the body. When assembled, the body and the face define a closed volume.

Fairway wood-type golf clubs as described herein may include: (a) a club head with a volume of at least 300 cc; (b) a shaft member attached to the club head, wherein the golf club has a length between 37 and 43 inches; and (c) a grip or handle member attached to the shaft member. The club head may further include: (1) a ball striking face, wherein the ball striking face has a loft angle between 12 and 32 degrees; and (2) a club head body engaged or integrally formed with the ball striking face, with a sole portion that includes a ground-engaging surface.

Golf club heads having sensors configured to measure one or more swing parameters are provided. The golf club head may include several gyroscopes and accelerometers. In one embodiment, the club head contains three gyroscopes that measure angular rate data along different orthogonal axes. At least one gyroscope may an analog gyroscope. Accelerometers may provide data regarding the three orthogonal axes associated with the gyroscopes. The club head may further include software and/or hardware that perform computer-executed methods for determining one or more swing parameters. Exemplary club heads may include a display device for displaying an output of the swing parameter(s). Further aspects of the invention relate to novel methods and algorithms for calculating measurements relating to the swing parameters.

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 shaft engaging member including a rotation-inhibiting structure; (b) a club head engaging member including a shaft-receiving chamber and a retaining structure for engaging the rotation-inhibiting structure; and (c) a securing system for releasably securing the shaft engaging member with respect to the club head engaging member. 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 engaging member so as to allow adjustment of the shaft position with respect to the club head.

The invention relates generally to golf clubs and golf club heads that enable users, club fitters, club manufacturers, and the like to selectively control, change, and customize aspects of the “sound” associated with the golf club and golf club head when it strikes a golf ball. Golf clubs and golf club heads according to this invention may include: a) a club head body; b) a ball striking face engaged with or integrally formed as part of the club head body; c) a hosel member engaged with or integrally formed as at least a portion of the club head; and d) means for changing a sound emanated by the club head when a golf ball contacts the ball striking face. A user may change the vibrational characteristics associated with the club head when a golf ball is struck, thereby changing the sound emanating from the club head when a golf ball is struck.
