AI Technical Summary

Benefits of technology

The present invention relates to a method for adjusting a series of golf clubs without modifying their moment of inertia or swingweight. The method involves adjusting the mass of the head and / or shaft of each golf club to achieve a substantially identical moment of inertia and swingweight. This allows for a series of golf clubs with a consistent moment of inertia and swingweight. The adjustment of the mass is done by adding or removing tip weights from the head or shaft, or by replacing the grip with a different grip with a different mass. The method also allows for the adjustment of the address position of each golf club by modifying the length of the shaft or lie angle. The technical effect of the invention is to provide a method for adjusting golf clubs that allows for a consistent moment of inertia and swingweight without modifying the moment of inertia or swingweight.

Problems solved by technology

At this time, no method is known making it possible to adjust a series of golf clubs with a constant moment of inertia and a constant swing.

[0039]Calculation of the Swingweight

[0040]As an example, the swingweight can be calculated as follows (cf. Computing Heft, The Tutleman site, Oct. 8, 2018,

[0041]https: / / www.tutelman.com / golf / design / swingwt2.php):

SW=Lc×(T+S2)-14(T+S)-10×G50-124[Math1]

where[0042]SW is the swingweight rounded to the closest unit;[0043]Lc is the length of the club (in inches);[0044]T is the weight of the Head of the club (in grams);[0045]S is the weight of the shaft (in grams);[0046]G is the weight of the grip (in grams).

[0047]Calculation of the Moment of Inertia

[0048]As an example, the moment of inertia can be calculated as follows (cf.

[0049]Computing Heft, The Tutleman site, Oct. 8, 2018, https: / / www.tutelman.com / golf / design / swingwt2.php):

MOI=Lc2×(T+S3)+10×G[Math2]

[0050]where[0051]Lc is the length of the club (in inches);[0052]T is the weight of the Head of the club (in grams);[0053]S is the weight of the shaft (in grams);[0054]G is the weight of the grip (in grams).

Abstract

The invention relates to a method for adjusting a series of golf clubs each comprising a shaft, a head at the proximal end of the shaft and a grip at the distal end of the shaft; said method comprising the following steps: adjusting the mass of the head of each golf club and / or, adjusting the mass of the shaft near the distal end of the shaft, such that each golf club has a substantially identical moment of inertia; then adjusting the mass of the grip of each golf club and / or adjusting the mass of the shaft near the proximal end of the shaft, such that each golf club has a substantially identical swingweight. The invention also relates to a series of golf clubs adjusted using the method according to the invention.

Description

FIELD OF THE INVENTION[0001]The present invention relates to the field of golf. More specifically, the invention relates to a method for adjusting a series of golf clubs as well as a series of golf clubs adjusted using this method.BACKGROUND OF THE INVENTION[0002]Playing golf requires the use of several golf clubs, also called clubs. Each club comprises a shaft, a head at one end of the shaft to strike the golf ball, and a grip, at the other end of the shaft, by which the golf player holds the club. Among golf clubs, there are three main families based on the head of the club: woods, irons and the putter. Each player generally has several irons and several woods making it possible for the golf ball to fly over different distances. Typically, a golf player will have between 6 and 11 irons and between 2 and 5 woods.[0003]The movement performed in order to propel the ball with the golf club demands great precision from the player. To be able to repeat this movement irrespective of the ...
