Adjustable golf club and system and associated golf club heads and shafts

摘要

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.

主权项

1. A golf club head comprising:
a body defining a ball striking surface, a crown, a sole, a heel, a toe and a back; and an adjustment member operably connected to the body, andwherein the body and adjustment member are structured such that the adjustment member adjusts a first parameter associated with the body among a plurality of positions and wherein in response to the adjustment of the first parameter, a second parameter associated with the body remains constant within a predetermined tolerance, wherein the first parameter is a loft angle and the second parameter is a face center location of the golf club head,wherein the face center location is measured in space in relation to an origin point with an X′Y′Z′ coordinate system defined from the origin point, with a Z′ axis extending along a direction of a shaft axis, an X′ axis parallel with a vertical plane and normal to the Z′ axis, and a Y′ axis normal to the X′ and Z′ axes,wherein the predetermined tolerance for the face center location is approximately 2 mm from a reference face center location measured in space in relation to the origin point, wherein the reference face center location is measured at a reference position of the golf club head prior to the adjustment of the first parameter, andwherein the predetermined tolerance of the face center location is defined by a face center tolerance sphere with a center of the face center tolerance sphere defined as the reference face center location, wherein when the first parameter is adjusted, the face center location is no greater than 2 mm away in any direction from the center of the face center tolerance sphere.
