Embodiment Construction

[0092] The present invention is an interchangeable shaft system for connecting a golf club shaft to a club head. Such a system may be used to provide a personalized fit of different shaft types to club heads and / or to provide adjustability between shafts and club heads. Several embodiments of the invention are described below.

[0093] Unless expressly stated otherwise, all numerical ranges, amounts, values ​​and percentages in the ensuing part of the specification such as amounts of material, moment of inertia, position of center of gravity, inclination and draft angles and other properties are to be regarded as having limited The word "about", even though the term "about" may not be clearly associated with a value, amount, or range. Accordingly, unless indicated to the contrary, the numerical parameters set forth in the ensuing portions of the specification and appended claims are approximations that may vary depending upon the desired properties sought to be obtained by th...

Abstract

PROBLEM TO BE SOLVED: To provide a golf club incorporating an interchangeable shaft system.SOLUTION: In the golf club, a shaft sleeve 516 is coupled to an end of a shaft 514 and is received in a hosel 534 included in a club head 510. The shaft sleeve 516 is removably coupled to the club head 510. Hosel 534 and shaft sleeve 516 alignment features provide discrete orientations between the shaft 514 and club head 510.

Description

[0001] field of invention [0002] [0002] The present invention relates generally to golf clubs, and more particularly to golf clubs having improved connections between shafts and club heads that provide interchangeability and adjustability. Background technique [0003] In order to improve their game, golfers often customize their equipment to fit their particular swing. Lacking a convenient way to make shafts and heads interchangeable, a shop or business offering a personalized fit must either have many clubs with specific characteristics, or have to change a particular club with complex disassembly and reassembly steps. For example, if a golfer wants to try a golf club shaft with different flex characteristics, or use a club head with a different mass, center of gravity, or moment of inertia, it has not been practical to make such changes in the past. Golf equipment manufacturers have increased the variety of clubs that a golfer may obtain. For example, a particular model...
