(57) [Summary] [Purpose] The production of golf clubs that can improve flight distance, directionality and ball control. [Structure] A golf club shaft is provided with fine irregularities or linear protrusions.

Description

【考案の詳細な説明】[Detailed description of the device]

【0001】[0001]

【産業上の利用分野】[Industrial applications]

本考案は、ゴルフクラブのシャフトの構造に関するものである。 The present invention relates to a golf club shaft structure.

【0002】[0002]

【従来の技術】[Prior art]

従来、シャフトの表面は平に仕上げるのみで、シャフトの径を細くする以外に は、空気抵抗を少なくするための工夫は特に施されていない。 Conventionally, the surface of the shaft is only finished to be flat, and other than reducing the diameter of the shaft, no special measures have been taken to reduce the air resistance.

【0003】[0003]

【考案が解決しようとする課題】[Problems to be solved by the device]

ゴルフのクラブシャフトが、空気を切りながら移動する時に、シャフトの背面 に「カルマン渦」が発生する。この渦は空気抵抗を増すと共に、渦がシャフトか ら剥離する際にシャフトを左右に振動させる力が発生するという問題がある。 When the golf club shaft moves while cutting air, “Karman vortex” is generated on the back surface of the shaft. This vortex increases air resistance, and when the vortex separates from the shaft, there is a problem that a force is generated that vibrates the shaft from side to side.

【0004】[0004]

【課題を解決するための手段】[Means for Solving the Problems]

ゴルフクラブのシャフトの表面に、一様な空気の流れを防止する細かい凹凸あ るいは線状の凸を施す。 The surface of the golf club shaft is provided with fine irregularities or linear protrusions that prevent uniform air flow.

【0005】[0005]

【作用】[Action]

カルマン渦の発生を防止する。 Prevents the Karman vortex from occurring.

【0006】[0006]

【実施例】【Example】

実施例について、図面を参照して説明する。 図1は、0.2〜0.5mm程度の粒子をシャフト表面に付着させる等によっ て細かい凹凸を施した例である。図4は、同じく0.2〜0.5mm程度の線状 の凸を1〜2cmのピッチで螺旋に施した例である。 Examples will be described with reference to the drawings. FIG. 1 shows an example in which fine irregularities are formed by adhering particles of about 0.2 to 0.5 mm to the shaft surface. FIG. 4 shows an example in which linear projections of about 0.2 to 0.5 mm are also spirally formed at a pitch of 1 to 2 cm.

【0007】 線状の凸は、図6の断面を45°前後の角度で横切るように配置すれば、線状 の凸が連続であっても不連続であってもよく、また、線状の凸の配置はは任意で よい。あるいは、線状の凸でなくとも、細かい凹凸を帯状に施してもよく、細か い凹凸と線状の凸を組み合わせてもよい。The linear projections may be continuous or discontinuous if they are arranged so as to cross the cross section of FIG. 6 at an angle of about 45 °, and the linear projections may be continuous or discontinuous. The convex arrangement may be arbitrary. Alternatively, fine irregularities may be applied in a band shape instead of the linear convexities, and fine irregularities and linear convexes may be combined.

【0008】 なお、この効果は、直径1cm前後の丸い棒にタコ糸を螺旋状に1cm程度の ピッチで巻き付けたものと、巻き付けないものとを水中に立てて、水を切るよう にすばやく移動することによって、如実に体験することができる。[0008] The effect is that a round rod having a diameter of about 1 cm and spirally wound octopus yarn at a pitch of about 1 cm and a non-wound one are put up in water and quickly moved to drain water. By doing so, you can really experience it.

【0009】[0009]

【考案の効果】[Effect of device]

空気抵抗の低減、振動の抑止、およびこれに伴うインパクト後のヘッドとボー ルの解離の抑制がなされる結果、飛距離のアップ、方向性の改善、ボールコント ロールの容易化が実現される。 但し、この効果を十分に活用するには、インパクト後のフォロースイングにお いてヘッドスピードを落とすことなく、クラブヘッドをボールに密着したままの 状態を保ちながら、ボールへの力の伝達とボールのコントロールを行うスイング をする必要がある。逆に、このクラブを使いこなすスイングをマスターすること によって、ゴルファーのレベルアップが促進されることとなる。 As a result of reducing air resistance, suppressing vibration, and suppressing the dissociation of the head and ball after impact, the flight distance is increased, the direction is improved, and the ball control is facilitated. However, in order to fully utilize this effect, the force transfer to the ball and the ball's force must be maintained while keeping the club head in close contact with the ball without reducing the head speed in the follow swing after impact. You need to make a swing to control it. On the contrary, mastering the swing to master this club will promote the golfer's level up.
