Abstract: The present invention relates to golf clubs, more particularly to a stabilized golf club that accounts for human factors in its design and configuration. In accordance with one embodiment a berish bracket is attached to two points on a club head for increased controllability The shaft attaches to the berish and provides the force necessary to propel the ball forward but, due to the configuration of the berish bracket, the forces is applied at two points along the club head. In accordance with another embodiment, the club shaft is configured to point forward of the moment of mass of the club head, thereby further increasing controllability In accordance with other embodiments, a configurable knuckle is configured between the club shaft and the berish bracket for is optimizing controllability for an individual golfer.

Abstract: A putter has an elongated head with a face along a long side of the head and an end surface along a short side of the head both for striking a ball. The shaft can be positioned to strike a ball with either the face or the end surface. The end surface may have a loft of 5 degrees or more. The shaft is held in each position such that it does not move appreciably while putting, but can be moved to another position by a golfer without tools. In some embodiments, all contact between the shaft and the head is made through one or more resilient, non-metallic materials such as rubber. In some embodiments, a ball on the end of the shaft is held in a cavity in the head by an annular nut. O-rings separate the ball from components fixed to the head and the nut can be tightened or loosened to adjust the friction provided by the O-rings.

Abstract: A golf putter and method of making a putter is provided in which a front heel face of the putter defines a bore for receiving one end of a hosel, the hosel defining a substantially right angled bend. A free end of the hosel engages the putter shaft. The hosel provides a desired offset distance from the club strike face. Rotation of the hosel relative to the bore also provides an adjustment mechanism by which the lie angle and face balancing of the club may be achieved.

Preferably, the flange includes a plurality of cavities for receiving interchangeable weights for altering the weight characteristics of the club head.

Abstract: The present invention provides: a golf collimator and a golf club therewith which make it easy for a player to ascertain a straight direction without a tense feeling when holding a golf club at the ready. A golf collimator (1), which is a device to be fixed on a head of a golf club so as to ascertain a straight direction, comprises a recess (12) and three points arranged around the recess (12), wherein a recess (12) is of such a concave shape as is open in a direction which will be front when holding a club at the ready and as narrows the width of the recess with the approach to the bottom of the recess, and wherein the three points (13) are arranged at the back and on the right and the left of the recess. A golf club is fitted on a head with the collimator structure.

Abstract: A putter head is provided with a plane, flat golf ball engaging surface which extends between opposite ends of the putter head. Mounted in a recess formed in the putter head rearwardly of its face is an adjustable sighting line support having in its upper surface an elongage sighting line which registers at one end with the face of the head, and extends rearwardly therefrom. The support is mounted for limited adjustment about an axis that extends parallel to and is spaced rearwardly of the face of the putter head. In one adjusted position the sighting line extends at right angles rearwardly from the putter face in a manner similar to conventional putter sighting lines. However the support is mounted for limited rotational movement for up to at least 10° either clockwise or counterclockwise about its pivotal axis thereby to cause the sighting line to be secured in any one of a plurality of different angular positions other than 90° relative to the face of the putter head.

Abstract: A golf club head comprises a head portion and a neck portion which has a cross section with a flexible section. The longitudinal direction of the cross section of the flexible section and the heel-toe direction of the golf club head form an angle ranging between zero and 90 degrees. In light of the short axial direction of the cross section of the flexible section having a better flexibility, when the golf club head hits a ball, the flexibility in the left front direction or the right front direction is better than other direction. The ball has a tendency to travel along the predetermined side so as to correct the golfer's habit to hit the ball to travel in other side.

Abstract: A retractable golf club alignment device and method for use for assisting a golfer to hit the sweet spot of a golf ball with the optimum spot on the face of a golf club head. The device comprise a retractable extension pin mounted through the optimum spot on the club face which extends from the face of the golf club head and provides a three dimensional alignment aid to the golfer and retracts flush with the golf club face when the golfer hits a golf ball. The retractable extension pin is mounted in a pin bearing and extended via a pin extender unit. In use, the golfer mentally notes the position and extension axis of the extension pin and then proceeds with a normal swing as if the extension pin was not present. The extension pin does not affect the expected trajectory of the golf ball.

Abstract: A golf club useful as a putter and including an elongate club shaft terminating at a lower end in a coupling structure for attachment to a cooperating coupling carried by an upper end of a stub shaft of any of a family of selectable putter heads. In the illustrated embodiment of the invention, the club shaft carries a yoke, and the stub shaft of the club head carries a disc. The disc is slideably received between spaced parallel plates of the yoke. A hinge-like camming lever is pivotal to draw the plates of the yoke together to lock and to secure interference-faced surfaces of the disc and the plates together to establish selectable, vertical angular attitudes of the club head, to meet a golfer's particular preference or needs.
