Abstract
In general, aspects of this invention relate to golf clubs or golf club components incorporating adjustment members that permit ready adjustability of golf club parameters and/or interchangeability of golf club components to change a golf club configuration, and methods for providing golf clubs. According to aspects of this invention, an adjustment member may be utilized to allow the adjustability of a golf club parameter to change a golf club configuration, while ensuring there is substantially no change to other club or club head variables, parameters or characteristics. According to another aspect of this invention, an adjustment member may be utilized to allow the adjustability of two golf club parameters independently to change a golf club configuration, while ensuring there is substantially no change to other club or club head variables, parameters or characteristics.

25. A golf club head comprising:
-
a body defining a ball striking surface, a crown, a sole, a hosel, a heel, and a toe; and
an adjustment member having a shaft adapter with a shaft adapter axis, the shaft adapter operably connected to the body and rotatable about the shaft adapter axis, and wherein the body and adjustment member are structured such that the adjustment member independently adjusts a loft angle among a first plurality of positions and the adjustment member independently adjusts a second parameter associated with the body among a second plurality of positions wherein in response to the adjustment of the loft angle and the second parameter, a third parameter associated with the body remains substantially unchanged within a predetermined tolerance, wherein the third parameter is one of the following;
the golf club head'"'"'s location of a center of gravity, a face center, or a sole contact point, wherein each location is measured from a hosel origin point located at an intersection of the shaft adapter axis and an uppermost edge the shaft adapter, andfurther wherein when the third parameter is the location of a center of gravity of the golf club head, and the predetermined tolerance for the location of the center of gravity is approximately 3 mm from a reference center of gravity determined before the adjustment of the loft angle and the second parameters, and wherein when the third parameter is a location of the face center of the golf club head, and the predetermined tolerance for the location of the face center is approximately 3 mm from a reference face center determined before the adjustment of the loft angle and the second parameters, and wherein when the third parameter is the sole contact point, the predetermined tolerance for the location of the sole contact point is 4 mm from a reference sole contact point determined before the adjustment of the loft angle and the second parameters. - View Dependent Claims (26, 27, 28, 29, 30)

31. A golf club head comprising:
-
a body defining a ball striking surface, a crown, a sole, a hosel, a heel, and a toe; and
an adjustment member having a shaft adapter with a shaft adapter axis, the shaft adapter operably connected to the body and rotatable about the shaft adapter axis, and wherein the body and the adjustment member are structured such that the adjustment member adjusts a loft angle of the body among a plurality of loft angles and the adjustment member adjusts a face angle of the body among a plurality of face angles, wherein in response to the adjustment of the loft angle and the face angle, a parameter associated with the body remains substantially unchanged within a predetermined tolerance, wherein the third parameter is one of the following;
the golf club head'"'"'s location of a center of gravity, a face center, or a sole contact point, wherein each location is measured from a hosel origin point located at an intersection of the shaft adapter axis and an uppermost edge the shaft adapter, andfurther wherein when the third parameter is the location of a center of gravity of the golf club head, and the predetermined tolerance for the location of the center of gravity is approximately 3 mm from a reference center of gravity determined before the adjustment of the loft angle and the face angle, and wherein when the third parameter is a location of the face center of the golf club head, and the predetermined tolerance for the location of the face center is approximately 3 mm from a reference face center determined before the adjustment of the loft angle and the face angle, and wherein when the third parameter is the sole contact point, the predetermined tolerance for the location of the sole contact point is 4 mm from a reference sole contact point determined before the adjustment of the loft angle and the face angle. - View Dependent Claims (32, 33, 34)

35. A golf club comprising:
-
a golf club head that includes a body defining a ball striking surface, a crown, a sole, a hosel, a heel, and a toe; an adjustment member having a shaft adapter with a shaft adapter axis, the shaft adapter operably connected to the body and rotatable about the shaft adapter axis; and a shaft connected to shaft adapter and the golf club head, wherein the body and the adjustment member are structured such that the adjustment member independently adjusts a loft angle of the club head among a plurality of loft angles and the adjustment member independently adjusts a face angle of the club head among a plurality of face angles, wherein in response to the adjustment of the loft angle and the face angle, one or more parameters associated with the body remain substantially unchanged within a predetermined tolerance, wherein a first parameter is defined as a location of a center of gravity of the golf club head measured from a hosel origin point located at an intersection of the shaft adapter axis and an uppermost edge the shaft adapter and the predetermined tolerance for the location of the center of gravity is approximately 3 mm from a reference center of gravity determined before the adjustment of the loft angle and the face angle, and a second parameter is defined as a location of a face center of the golf club head measured from the hosel origin point, and the predetermined tolerance for the location of the face center is approximately 3 mm from a reference face center determined before the adjustment of the loft angle and the face angle, and a third parameter is defined as a moment of inertia of the golf club head about any one of the X-axis, Y-axis, or Z-axis, wherein the predetermined tolerance for the moment of inertia is approximately 10.0 KG-mm2 from a reference moment of inertia. - View Dependent Claims (36, 37, 38, 39)
