Abstract: A golf club includes a shaft, a hosel mounted on the lower end of the shaft and a golf club head mounted on the hosel for pivotal movement about an axis which is generally horizontal when the club is in an addressed position. The golf club head includes a blade portion pivotally mounted to a heel portion. A lever is operably connected to a linkage assembly so that the lever can be moved from a first position in which the linkage assembly secures the blade to the heel and a second position in which the linkage assembly allows disengagement of the blade from the heel so that the blade may be rotated relative to the heel.

Abstract: To adjust loft and lie angles of golf clubs, a laser beam projector is mounted coaxially in a bore of a golf club head hosel, a laser beam projected, and the hosel is bent in a single direction until the beam aligns with a target or mark placed on a fixed surface which has a predetermined relationship to a clamp for the club head. Each club head is clamped in a predetermined position relative to its face and sole and the clamp is mounted in a predetermined relationship relative to the target surface. The target is arranged coaxially with the desired end position of the hosel axis. The projector is mounted in the hosel bore by means of an expanding collet which is inserted into and then snuggly aligned internally and coaxially in the hosel bore.

Abstract: A hosel interface device for interconnection of the golf club shaft and the golf clubhead, the device having a portion which is made intentionally bendable to provide any desired extent of variation in lie angle and face angle in virtually an infinite number of increments. The invention employs a bending region along a portion of an otherwise straight exterior hosel interface or coupling. The hosel interface is configured to be inserted into the typical hosel area location of a golf club head such as a wood or iron head. The hosel interface also provides an elongated receptacle for receiving the clubhead end of a shaft. The bending region is between the clubhead insertion region and the shaft receptacle region of the hosel interface.

Abstract: In an iron club set, the lie angle of each iron club in an iron club set is selected to be 61 degrees or larger. The lie angles of the iron clubs are set at a fixed value for every type of the iron clubs including a short iron to a long iron or progressively increase in angle value from the short iron to the long iron. Further, a ratio (L/H) of the minimum height (L) of the face at the heel to the maximum height (H) of the face of the club head, progressively increase in value in going to the long irons.

Abstract: The hosel construction includes a plug member extending downwardly for engaging a club head having a club face. A neck member, extending angularly upwardly from the plug member, engages a shaft to complete a golf club. The neck member extends in a generally transverse dimension to determine a lie angle between the shaft and the club head. The neck member also extends in a generally longitudinal dimension to determine a longitudinal angle, such as a face angle for the club face.

Abstract: A golf club includes a head having a striking face and a shaft having first and second ends such that the shaft defines an axis. The club further includes a hosel assembly including a member having first and second ends. The first end of the member is fastened to the head. The hosel assembly also includes a hosel having first and second ends. The first end of the hosel is fastened to the shaft. The second end of the hosel is pivotally fastened to the second end of the member. A cam member is pivotally fastened to a first one of the hosel and the member about an axis. The cam member has a cam surface offset from the axis. The cam surface is engaged with a second one of the hosel and the member. The rotation of the cam member about the axis causes the cam surface to pivot the member relative to the hosel to change the lie or loft angle of the putter head relative to the shaft.

Abstract: A golf putter is provided having improved performance and custom adjustability. The putter has an adjustable-lie raised hosel which can be adjusted for a particular golfer, yet which may be semi-permanently fixed in position so that no adjustment can be readily made or worked loose during a round of golf play. To this end, the hosel has two members which are pivotally joined at a joint which includes a shaped sleeve mounted onto a projection attached to one hosel member and received in a shaped bore connected to the other hosel member. Rotation of the sleeve with respect to the projection and the bore results in an adjustment of the lie angle. Also, the putter has a sole sensor shaped to permit rocking on the ground in a lie-varying direction. Further, the putter includes a multiple replaceable and striking face plates for providing various lofts. Various weights are provided which attach to a rear of the selected face plate.

Abstract: A golf club wherein the lie angle of the shaft with respect to the head may be adjusted such that the sole, toe and heel of the club may be parallel to the ground and configured for use by both left-handed and right-handed players. The attachment of the golf club head to the shaft also permits adjustment of the golf club head to either the open, standard, or closed configuration to compensate for a player's swing.

Abstract: An adjustable golf putter which has an attachment means which allows the shaft to be removed from the putter head, and allows the angle between the golf club shaft and the golf club putter head to be adjusted. An array of angle selection notches and an angle selection tooth are provided on the first end of the shaft. These angle selection notches correspond to a variety of angles between the shaft and the putter head body. Choice of an angle selection notch positions determines the angle between the putter shaft and the putter head body and holds it at that angle in a positive manner. The putter also has interchangeable face plate assemblies, which provide for changing the mass of the putter head and the loft angle of the striking face.

Abstract: A golf putter having a lie and offset adapter for selectively setting and/or adjusting the lie and offset of the putter. The adapter may comprise a spacer having a lower socket extending from a first end along a first longitudinal axis and a second socket extending from a second end along a second longitudinal axis. The length of the spacer and the orientation of the sockets are set to provide the desired lie and offset of the putter. The golf putter has a head with a face for striking a golf ball, a lower shaft segment and an upper shaft segment. The head is connected to a lower shaft segment which, in turn, is attached to the lower socket of the adapter. A lower end portion of the upper shaft segment connects to the upper socket of the adapter. Alternatively, the open end of a hosel, which extends from the putter head, may take the place of the lower shaft segment. The lie and offset of the putter are selectively set during assembly by installing an adapter configured for the desired lie and offset.

Abstract: An adjustable golf putter includes an elongated shaft having an upper end with a handle and a lower end with a spherical tip portion. A putter head has an external surface and a socket that includes an enlarged open end portion for receiving the enlarged tip of the shaft, the socket also having a restricted opening through which the shaft passes, but which will not allow passage of the spherical head. Pins on the spherical tip cooperate with vertical slots along the socket to restrict adjustability to two plane. A plurality of set screw openings extend between the socket and the external surface of the putter head. A plurality of set screws extend respectively through the plurality of set screw openings each having a pointed tip that engages the enlarged spherical end of the shaft. The enlarged spherical end of the shaft can be of softer metal material than the material for the set screws.
