Definitions
- the present invention relates to a golf club set.
- a golf club set (for example, an iron set) has a plurality of golf clubs (for example, a 5th iron to a 10th iron) having different counts. Golf clubs with different numbers usually have different lengths and total club weights (shaft length and head weight).
- Conventional golf club sets are generally assembled by selecting a shaft and a head so that the swing weights (swing balance) of all counts having different lengths and total club weights are substantially the same.
- the swing weight is a numerical value that indicates how well the golf club head is used (how easy it is to feel the weight of the head when swinging or waggle). The heavier the golf club, the greater the weight of the head. The easier and lighter the golf club, the harder the head feels.
- a club inertia moment (MOI [kg ⁇ cm 2 ]) is known as an index different from the swing weight.
- the club inertia moment is defined as the sum of the inertia moments from the grip ends of the head, the shaft, and the grip, and is used as an index indicating the swinging comfort of the golf club.
- the greater the moment of inertia of the club the harder it is to swing, and the smaller the moment of inertia of the club, the easier it is to swing.
- the present inventors can easily swing each golf club in the golf club set.
- the present invention has been completed on the basis of the fact that it is possible to arrange them. That is, according to the present inventors, it is easier for the player to swing the golf club set when the moment of inertia of the golf club is more uniform in the entire golf club set than the size of each single golf club. It was found that it is evaluated.
- each golf club of a golf club set having conventional swing weights has a small (large) club inertia moment (MOI [kg ⁇ cm 2 ]) as the count becomes large (small). That is, in the conventional golf club set, the actual situation is that the moment of inertia of the club (that is, the swing feeling) is changed depending on the number of the golf club. It is speculated that this may be one of the causes of poor performance due to the count (especially, the club with the lower count is weak).
- the present invention has been made on the basis of the above problem awareness, and an object thereof is to obtain a golf club set capable of obtaining a stable swing feeling suitable for a player regardless of the golf club number.
- the present inventors have moved away from the general tendency that swinging is easier (easier to swing) as the moment of inertia of the club becomes larger (smaller). It has been found that the same moment of inertia of the club is important for obtaining a suitable and stable swing feeling that eliminates the disadvantages of the count.
- the present invention has been completed with the concept of aligning the values of the club moments of inertia of the golf clubs of the golf club set. Of course, the value of the club inertia moment varies depending on the individual player.
- the golf club set of the present invention is a golf club set having a plurality of golf clubs having different counts, each golf club having a head and a grip fixed to the distal end portion and the proximal end portion of the shaft.
- the grip moment of inertia of the golf clubs is substantially constant regardless of their count; the head inertia moments of the plurality of golf clubs decrease as the count increases;
- the shaft moment of inertia of the club increases as the count increases; the decrease in the head inertia moment and the increase in the shaft inertia moment are substantially offset so that the clubs of the plurality of golf clubs The moments of inertia are substantially the same; and the plurality of golf clubs constituting the plurality of golf clubs.
- Golf club shaft of the book as the the count is increased, and a shaft barycentric position the shaft weight is increased to move the shaft distal end; are characterized.
- the reference golf club and the remaining arbitrary golf club satisfy the following conditional expression (1).
- X Club moment of inertia of the reference golf club (MOI [kg ⁇ cm 2 ])
- Y Club inertia moment (MOI [kg ⁇ cm 2 ]) of any remaining golf club, It is.
- the golf club set of the present invention preferably satisfies the following conditional expression (1 ′) within the conditional expression range defined by conditional expression (1).
- At least a part of the plurality of golf club shafts can have one or both of a metal cylinder and a metal foil whose weight increases as the count increases on the shaft tip side.
- the plurality of golf clubs may include at least 6 iron clubs from 5 iron to 10 iron.
- the present invention it is possible to obtain a golf club set capable of obtaining a stable swing feeling suitable for a player regardless of the golf club count.

同図に示すように、ゴルフクラブのクラブ慣性モーメントMOITは、当該ゴルフクラブを構成するヘッド、シャフト、グリップの慣性モーメントMOIH、MOIS、MOIGの総和によって算出される。(MOIT=MOIH+MOIS+MOIG)

(1’)0.998X<Y<1.002X
グリップ慣性モーメントMOIGは、クラブの番手にかかわらず一定(略一定で少しだけずれていてもよい)となっている。
ヘッド慣性モーメントMOIHは、クラブの番手が大きくなるに連れて減少している。
シャフト慣性モーメントMOISは、クラブの番手が大きくなるに連れて増加している。
そして、クラブの全番手を通じて、ヘッド慣性モーメントMOIHの減少分とシャフト慣性モーメントMOISの増加分が略相殺されることで、クラブ慣性モーメントMOITが略同一となっている。
プリプレグP1は、シャフト先端部に巻かれる先端部分層であり、繊維方向がシャフト長手方向と平行をなす0°プリプレグである。
プリプレグP2、P3は、シャフト全長に巻かれる全長層であり、繊維方向がシャフト長手方向に対して対称(本実施形態では±45°)をなすバイアスプリプレグである。
プリプレグP4、P5、P6は、シャフト全長に巻かれる全長層であり、繊維方向がシャフト長手方向と平行をなす0°プリプレグである。
プリプレグP7は、シャフト先端部に巻かれる先端部分層であり、繊維方向がシャフト長手方向と平行をなす0°プリプレグである。
8番シャフト8S~10番シャフト10Sは、金属箔MF1に加えて、プリプレグP4とプリプレグP5の間に介在させて、シャフト先端部に巻かれる先端部分層である金属箔MF2を有している。
金属箔MF1と金属箔MF2は、例えば、銅、ステンレス、アルミニウム等の材料から構成されている。
金属箔(5番シャフト5S~7番シャフト7Sでは金属箔MF1、8番シャフト8S~10番シャフト10Sでは金属箔MF1と金属箔MF2)は、クラブの番手が大きくなるに連れてその重量が増加する(5番シャフト5Sでは1.07g、6番シャフト6Sでは1.91g、7番シャフト7Sでは2.87g、8番シャフト8Sでは4.41g、9番シャフト9Sでは5.99g、10番シャフト10Sでは7.69g)。
すなわち、第1態様は、シャフト重量とシャフト重心位置の双方を番手毎に絶妙な調整量でシフトしていくので、第2態様と比べて、番手が大きいゴルフクラブシャフトひいてはゴルフクラブの重量を小さく抑え、番手が異なるゴルフクラブシャフトひいてはゴルフクラブの重量差を小さく抑えることができる(この点で第1態様が第2態様よりも優れていると言える)。
しかし、この第2態様であっても、クラブの全番手を通じてクラブ慣性モーメントが略一定となるように揃えられている(集約されている)ので、ゴルフクラブの番手にかかわらず、プレイヤーにとって好適な安定したスイング感覚を得ることができる。
