【発明の属する技術分野】
この発明は、ゴルフの正確なスイング技術を習得するのに適したスイング練習具に関する。
【0002】
【従来の技術】
ゴルフのスコアメイクにおける重要な要素の一つとして、打球の飛距離と方向性を挙げることができ、この飛距離と方向性の向上には正確なスイングが要求されることになる。
【0003】
ゴルフにおけるスイング技術の向上は、練習の積み重ねが基本であり、このため、場所を取らずにいつでも手軽にスイングの練習を行うことができるスイング練習具が既に提案されている。
【0004】
従来のスイング練習具は、後端側にグリップを有するシャフトの先端側に、所定の長さを有する一本の可撓紐を介して球状の重り部材を取り付けた構造になっており、シャフトのグリップを握ってスイングすると、シャフトの先端に可撓紐を介して取り付けた重り部材が、遠心力でシャフトの延長線状態で弧を描くことになり、重り部材の軌跡を目で捕らえることでスイングの状態を把握することができ、また、バックスイング時のトップにおいては、シャフトに対する重り部材の揺動の状態でトップの姿勢の良否が確認できる(特許文献1参照)。
【0005】
【特許文献1】
特開2003−10375号公報(図1、図2)
【0006】
【発明が解決しようとする課題】
ところで、上記した従来のスイング練習具は、シャフトの先端側に所定の長さを有する一本の可撓紐を介して重り部材を取り付けた構造になっているため、重り部材と可撓紐は、スイング方向に対して面としての方向性がなく、クラブヘッドのフェース面が正確な角度になるようなスイングの確認ができないという問題がある。
【0007】
即ち、スイングの練習において、ヘッドの正確なスイングの軌跡を習得することと同時に、スイング時におけるフェース面の所定角度の保持が重要な要素であるが、スイング時に重り部材や可撓紐を面として捕らえることができないと、グリップの状態に捩じれがあるか否かの判断ができず、スイング時にフェース面が正確な角度になる状態の技術の習得が行えないことになる。
【0008】
そこで、この発明の課題は、スイングの練習において、ヘッドの正確なスイングの軌跡を習得することができると同時に、スイング時に可撓紐を面として捕らえることができ、フェース面が正確な角度になる状態の技術の習得が可能になるゴルフのスイング練習具を提供することにある。
【0009】
【課題を解決するための手段】
上記のような課題を解決するため、この発明は、後端側にグリップを有するシャフトの先端側に、所定の長さを有する可撓紐を介して重り部材を取り付け、上記可撓紐がシャフトの先端側と重り部材の間で二条が並列状態になっている構成を採用したものである。
【0010】
上記シャフトの先端側に、上記重り部材の直径もしくは長さと略同径の外径もしくは長さを有するヘッド部材をシャフトに固定し、上記可撓紐は、重り部材の両側とヘッド部材の両側で二条が並列状態になるよう、ヘッド部材に対して重り部材を取り付けている構造とすることができる。
【0011】
ここで、重り部材は、ゴム等を用いた内部の芯材を外装材で覆った球形や円軸状に形成され、ヘッド部材は、シャフトに外嵌固定する小径部の先端側に重り部材と略同径の円筒状ケースを連成し、このケースの開口を螺着したキャップで閉鎖した構造や、シャフトに外嵌固定する取付け筒の先端に紐通し筒を直角に設けたT字形に形成され、上記可撓紐は、重り部材に対して球芯や軸心を通過するよう貫通させ、その両側をヘッド部材の円筒状ケースや紐通し筒に、両側外部の位置から内部に挿入し、両端の結び目を円筒状ケースや紐通し筒内に収納することにより輪状に形成され、これによって、可撓紐の重り部材とヘッド部材の間が、二条の並列状態になっている。
【0012】
上記可撓紐の二条が並列する部分は、シャフトのグリップを正確に握った状態で、上下に位置する配置に設定され、上下の並列する可撓紐間となり、スイング時に上下の可撓紐を目で捕らえることで、フェース面が正確な角度になる状態のスイング技術の習得が可能になる。
【0013】
【発明の実施の形態】
以下、この発明の実施の形態を図示例と共に説明する。
【0014】
図1(A)と(B)に示す第1の実施の形態のスイング練習具1は、ブランコ打法や振り子打法の習得に適した例であり、後端側にグリップ2を有する短いシャフト3と、このシャフト3の先端に固定したヘッド部材4と、ヘッド部材4に可撓紐5を用いて取り付けた重り部材6とからなり、上記重り部材6は、ゴム等を用いた内部の芯材7を適宜材料の外装材8で覆い、必要な重量を有する球形に形成されている。
【0015】
上記ヘッド部材4は、シャフト3に外嵌固定する小径部9の先端側に、重り部材6と略同径の外径に形成された円筒状ケース10を連成し、このケース10の開口を螺着したキャップ11で開閉自在に閉鎖した構造を有し、ケース10は筒状中芯12の外面を硬質のゴムや樹脂の外装部材13で覆って形成され、この円筒状ケース10の内部空間に必要な量のウエイトを収納することができるようになっている。
【0016】
上記可撓紐5は、重り部材6に対して球芯を通過するよう貫通させ、その両側端部をヘッド部材4の円筒状ケース10の先端部に、この円筒状ケース10の軸心を挟む両側外部の位置から内部に挿入し、両端を円筒状ケース10内で結ぶことにより輪状に形成され、これによって、可撓紐5の重り部材6とヘッド部材4の間が、図1(B)に示すように二条の並列状態になっている。
【0017】
ちなみに、重り部材6の球径と円筒状ケース10の外径は、6cm程度に設定し、可撓紐5の二条の並列部分は、重り部材6と円筒状ケース10への取り付け部分の間が11cm程度の長さに設定されている。
【0018】
なお、ヘッド部材4の円筒状ケース10は、スイング方向の前面に該当する部分を平坦面に形成したり、スイング方向に対する上面にマークを施して上下を確認できるようにしてもよく、この場合、円筒状ケース10に対する可撓紐5の二条の並列部分は、円筒状ケース10の上下に位置するような配置に設定されている。
【0019】
図2(A)と(B)に示す第2の実施の形態のスイング練習具1aは、ハンマー打法や振り子打法の習得に適した例であり、上記第1の実施の形態と同一部分には同一符号を付して説明する。
【0020】
この第2の実施の形態のスイング練習具1aは、後端側にグリップ2を有する長いシャフト3と、このシャフト3の先端に固定したヘッド部材4と、ヘッド部材4に可撓紐5を用いて取り付けた重り部材6とからなり、上記重り部材6は、ゴム等の適宜材料を用いた必要な重量を有する円軸形に形成され、その軸心に沿って紐通し孔が設けられている。
【0021】
上記ヘッド部材4は、シャフト3に外嵌固定する取付け筒14の先端に紐通し筒15を直角に設けたT字形に形成され、重り部材6と紐通し筒15は略同一長さに設定され、ヘッド部材4の紐通し孔と紐通し筒15に挿通した可撓紐5の両端を結んで、結び目を紐通し筒15内に収納している。
【0022】
なお、上記第2の実施の形態において、重り部材6は第1の実施の形態と同様の球状のものを用いるようにしてもよい。
【0023】
この発明のスイング練習具1、1aは、上記のような構成であり、シャフト3のグリップ2を握って可撓紐5の二条の並列部分が上下に位置するよう構え、バックスイングからダウンスイング、ホローへの一連のスイング運動を行う。
【0024】
バックスイングからトップの位置までは、シャフト3の先端に可撓紐5を介して取り付けた重り部材6が、遠心力でシャフト3の延長線状態で弧を描くことになり、トップの位置でシャフト3を止めると重り部材6は遠心力で後方に回動し、オーバースイングであると重り部材6はシャフト3に沿うような状態になるので、オーバースイングの矯正が行えることになる。
【0025】
上記トップの位置からダウンスイングに移行すると、重り部材6は遠心力で再びシャフト3の延長線状態で弧を描くことになり、重り部材6の軌跡を目視することにより、ヘッドに振れのない正しいダウンスイングを習得でき、また、インパクト位置において可撓紐5の重り部材6と円筒状ケース10又は紐通し筒15の間を目で確認する。
【0026】
上記可撓紐5の重り部材6と円筒状ケース10又は紐通し筒15の間は、上下に二条が並列しているので、インパクト位置において、上下の可撓紐5の間を面として捕らえることができ、上下の可撓紐5が略重なって見えたときは、フェースが正面を向いたスイングとなり、腕に捩じれがなく正確なグリップ状態であることが確認できる。
【0027】
また、上下の可撓紐5の内、上の可撓紐5が先に見えたらフェースが下向きで、上の可撓紐5が後に見えたらフェースが上向きであることが判断でき、従って、上下の可撓紐5が重なって見えるようにスイングを練習すれば、腕に捩じれがなく正確なグリップ状態でのスイング技術を習得することができ、球状の重り部材6を用いた第1の実施の形態においては、ブランコ打法や振り子打法のスイング練習が行え、また、第2の実施の形態のように、円軸状の重り部材6を用いたものは、ハンマー打法や振り子打法の練習が効果的に行えることになる。
【0028】
【発明の効果】
以上のように、この発明によると、後端側にグリップを有するシャフトの先端側に重り部材を取り付ける可撓紐を、シャフトの先端側と重り部材の間で二条を並列状態にしたので、ダウンスイング時に上下に二条が並列している可撓紐間を面として捕らえることができ、この面の垂直度合いを可撓紐の上下並列状態の目視によって確認することができ、スイング時のフェースの向きを知ることにより、腕に捩じれがなく正確なグリップ状態でのスイング技術を効率よく習得することができる。

TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a swing training device suitable for learning an accurate golf swing technique.
[0002]
[Prior art]
One of the important factors in golf score making is the flight distance and directionality of a hit ball. To improve the flight distance and directionality, an accurate swing is required.
[0003]
Improvement of the swing technique in golf is based on the accumulation of practice, and therefore, a swing practice tool that can easily practice swing at any time without taking up space has already been proposed.
[0004]
A conventional swing exercise device has a structure in which a spherical weight member is attached to a front end side of a shaft having a grip on a rear end side via a single flexible cord having a predetermined length. When swinging with the grip, the weight member attached to the tip of the shaft via a flexible string draws an arc in the state of extension of the shaft due to centrifugal force, and the trajectory of the weight member is caught by the eye and swings In addition, at the top during the backswing, it is possible to confirm whether the posture of the top is good or not in the state of the swing of the weight member with respect to the shaft (see Patent Document 1).
[0005]
[Patent Document 1]
JP-A-2003-10375 (FIGS. 1 and 2)
[0006]
[Problems to be solved by the invention]
By the way, the above-mentioned conventional swing training device has a structure in which the weight member is attached to the distal end side of the shaft via a single flexible cord having a predetermined length. In addition, there is a problem in that there is no directionality as a surface with respect to the swing direction, and it is not possible to confirm a swing such that the face surface of the club head has an accurate angle.
[0007]
That is, in the practice of swing, at the same time as learning the correct swing trajectory of the head, maintaining a predetermined angle of the face surface during the swing is an important element, but a weight member or a flexible string is used as a surface during the swing. If it cannot be caught, it cannot be determined whether or not there is a twist in the grip state, and it will not be possible to learn a technique in a state where the face surface is at an accurate angle during a swing.
[0008]
Therefore, an object of the present invention is to be able to learn a correct swing trajectory of a head in a practice of a swing, and at the same time, to catch a flexible string as a surface at the time of a swing, so that a face surface has an accurate angle. It is an object of the present invention to provide a golf swing training tool that enables the player to learn the state skill.
[0009]
[Means for Solving the Problems]
In order to solve the above problems, the present invention attaches a weight member to a front end side of a shaft having a grip on a rear end side via a flexible cord having a predetermined length, wherein the flexible cord is In this configuration, two strips are arranged in a parallel state between the distal end side and the weight member.
[0010]
On the distal end side of the shaft, a head member having an outer diameter or length substantially equal to the diameter or length of the weight member is fixed to the shaft, and the flexible string is provided on both sides of the weight member and on both sides of the head member. The weight member may be attached to the head member so that the two strips are in a parallel state.
[0011]
Here, the weight member is formed in a spherical shape or a circular axis shape in which an inner core material made of rubber or the like is covered with an exterior material, and the head member has a weight member on the distal end side of a small-diameter portion externally fixed to the shaft. A cylindrical case of approximately the same diameter is coupled, and the opening of this case is closed with a cap that is screwed on, or a T-shape is formed at a right angle with a string passing tube at the tip of a mounting tube that is externally fixed to the shaft. The flexible cord is penetrated through the weight member so as to pass through the ball core or the axis, and both sides thereof are inserted into the cylindrical case or the string passing tube of the head member from positions outside both sides, The knots at both ends are formed in a ring shape by being housed in a cylindrical case or a string passing tube, whereby the weight member and the head member of the flexible string are in a two-row parallel state.
[0012]
The portion where the two strips of the flexible cord are arranged in parallel is set to be arranged vertically, with the grip of the shaft accurately grasped, between the upper and lower flexible cords, and the upper and lower flexible cords are swinged during the swing. Capturing with the eyes enables the user to learn the swing technique in a state where the face surface is at an accurate angle.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0014]
The swing training device 1 of the first embodiment shown in FIGS. 1 (A) and 1 (B) is an example suitable for learning a swing hitting method or a pendulum hitting method, and is a short shaft having a grip 2 at a rear end side. 3, a head member 4 fixed to the tip of the shaft 3, and a weight member 6 attached to the head member 4 by using a flexible cord 5. The weight member 6 is an inner core made of rubber or the like. The material 7 is covered with an exterior material 8 of a suitable material, and is formed in a spherical shape having a required weight.
[0015]
The head member 4 has a cylindrical case 10 having an outer diameter substantially the same as that of the weight member 6 coupled to the distal end side of the small-diameter portion 9 fitted and fixed to the shaft 3. The case 10 has a structure in which it can be opened and closed with a screwed cap 11. The case 10 is formed by covering the outer surface of a cylindrical core 12 with a hard rubber or resin exterior member 13. The necessary amount of weight can be stored.
[0016]
The flexible cord 5 penetrates through the weight member 6 so as to pass through the spherical core, and both ends of the flexible cord 5 are sandwiched between the distal end of the cylindrical case 10 of the head member 4 and the axis of the cylindrical case 10. Both sides are inserted into the inside from the outside position, and both ends are connected in the cylindrical case 10 to form a ring shape, whereby the space between the weight member 6 and the head member 4 of the flexible cord 5 is as shown in FIG. As shown in the figure, there are two parallel lines.
[0017]
Incidentally, the spherical diameter of the weight member 6 and the outer diameter of the cylindrical case 10 are set to about 6 cm, and the two parallel portions of the flexible cord 5 are located between the weight member 6 and the portion attached to the cylindrical case 10. The length is set to about 11 cm.
[0018]
The cylindrical case 10 of the head member 4 may be formed such that a portion corresponding to the front surface in the swing direction is formed as a flat surface, or a mark is provided on the upper surface in the swing direction so that the top and bottom can be confirmed. The two parallel portions of the flexible cord 5 with respect to the cylindrical case 10 are set so as to be positioned above and below the cylindrical case 10.
[0019]
The swing training tool 1a according to the second embodiment shown in FIGS. 2A and 2B is an example suitable for learning a hammer hitting method or a pendulum hitting method, and is the same as that in the first embodiment. Are described with the same reference numerals.
[0020]
The swing exercise tool 1a according to the second embodiment uses a long shaft 3 having a grip 2 on the rear end side, a head member 4 fixed to the distal end of the shaft 3, and a flexible cord 5 for the head member 4. The weight member 6 is formed in a circular axis shape having a necessary weight using an appropriate material such as rubber, and a string through hole is provided along the axis thereof. .
[0021]
The head member 4 is formed in a T-shape in which a string passing tube 15 is provided at a right angle at the tip of a mounting tube 14 fitted and fixed to the shaft 3, and the weight member 6 and the string passing tube 15 are set to have substantially the same length. The string passing hole of the head member 4 is connected to both ends of the flexible string 5 inserted through the string passing tube 15, and the knot is stored in the string passing tube 15.
[0022]
In the second embodiment, the weight member 6 may be a spherical member similar to that of the first embodiment.
[0023]
The swing training tools 1 and 1a of the present invention have the above-described configuration, and hold the grip 2 of the shaft 3 so that the two parallel portions of the flexible string 5 are positioned up and down. Perform a series of swing movements to the hollow.
[0024]
From the back swing to the top position, the weight member 6 attached to the tip of the shaft 3 via the flexible string 5 draws an arc in the state of extension of the shaft 3 due to centrifugal force. When the weight 3 is stopped, the weight member 6 is rotated backward by centrifugal force, and when the weight is overswing, the weight member 6 is in a state of being along the shaft 3, so that the overswing can be corrected.
[0025]
When shifting from the top position to the downswing, the weight member 6 draws an arc again in the state of extension of the shaft 3 due to the centrifugal force, and by visually observing the trajectory of the weight member 6, the head does not swing without any deflection. A downswing can be learned, and between the weight member 6 of the flexible string 5 and the cylindrical case 10 or the string passing tube 15 is visually confirmed at the impact position.
[0026]
Since the upper and lower two strips are arranged in parallel between the weight member 6 of the flexible string 5 and the cylindrical case 10 or the string passing tube 15, the upper and lower flexible strings 5 are captured as a surface at the impact position. When the upper and lower flexible cords 5 appear to be substantially overlapped, the face is in a swing facing the front, and it can be confirmed that the arm is not twisted and is in an accurate grip state.
[0027]
Also, if the upper flexible string 5 of the upper and lower flexible strings 5 is seen first, it can be determined that the face is downward, and if the upper flexible string 5 is seen later, the face is upward. If the user practices a swing so that the flexible strings 5 appear to be overlapped, it is possible to learn a swing technique in an accurate grip state without twisting the arm, and the first embodiment using the spherical weight member 6 In the embodiment, swing practice such as swinging and pendulum hitting can be performed. In addition, as in the second embodiment, the one using the circular weight member 6 can be used for hammering or pendulum hitting. Practice can be done effectively.
[0028]
【The invention's effect】
As described above, according to the present invention, the flexible string for attaching the weight member to the distal end side of the shaft having the grip on the rear end side has two rows arranged in parallel between the distal end side of the shaft and the weight member. During the swing, the space between the flexible cords in which the two strips are arranged vertically can be captured as a surface, and the degree of perpendicularity of this surface can be confirmed by visual observation of the upper and lower sides of the flexible cord, and the orientation of the face during the swing By knowing this, it is possible to efficiently learn a swing technique in an accurate grip state without twisting the arm.
