Adjustable Golf Club and System and Associated Golf Club Heads and Shafts
First Claim
1. A method of providing a line of golf clubs, the line comprising at least one model of a first club type, the method comprising the steps of:
- designing a head for the first club type wherein the head has a reference loft angle; and
manufacturing the head to have the reference loft angle,wherein the head permits adjustment of at least the loft angle such that the head is adjustable to at least three settings for the loft angle, and a set of non-adjustable parameters for the head are substantially unchanged within a predetermined tolerance, such that P*n*x club configurations are provided in the line, wherein P is a number of settings for the loft angle, n is a number of shaft flex options, and x is a number of head types,wherein a first number of golf clubs in the line of golf clubs is less than a second number of golf clubs required to provide the same club configurations by designing and manufacturing multiple heads with individually designed-in loft angles.

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.

14. A method of providing a line of golf clubs, the line comprising at least one model of a first club type, the method comprising the steps of:
-
providing a club head for a first club type, wherein the club head has a reference loft angle; providing a shaft; and providing at least one adjustable member, wherein the at least one adjustable member is configured to be fitted to the club head, wherein the club head permits adjustment of at least a loft angle and at least one of a face angle and a lie angle such that the at least one adjustable member has at least three settings for the loft angle, such that the club head and the shaft are configured to adjust to at least three different loft angle configurations, and further wherein a set of parameters for the club head are substantially unchanged within a predetermined tolerance, and wherein a first number of parts in the line of golf clubs is less than a second number of parts required to provide the same loft angle configurations by providing multiple heads with individually designed-in loft angles. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)

28. A method of providing a line of golf clubs, the line comprising at least one model of a first club type, the method comprising the steps of:
-
designing a head for the first club type, wherein the head has a reference loft angle; manufacturing the head to have the reference loft angle; providing a shaft; providing at least one adjustable member; and fitting the at least one adjustable member to the head and the shaft, wherein the head permits adjustment of a loft angle of the head such that the at least one adjustable member has at least three settings for the loft angle, such that P*n*x club configurations are provided in the line, wherein P is a number of settings for the loft, n is a number of shaft flex options, and x is a number of head types, wherein P has a value of at least three, n has a value of at least three, and x has a value of at least one, wherein the loft angle of the head is adjustable up to +4 degrees and −
4 degrees from the reference loft angle, plus a tolerance of +/−
0.3 degrees, andwherein a first number of golf clubs in the line of golf clubs is less than a second number of golf clubs required to provide the same club configurations by designing and manufacturing multiple heads with individually designed-in loft angles. - View Dependent Claims (29, 30)
