【考案の詳細な説明】
この考案は、ゴルフボールの飛球方向を判定す
る打球練習具に関するものである。[Detailed Description of the Invention] This invention relates to a ball hitting practice tool that determines the flight direction of a golf ball.
ゴルフの打球練習において打球方向と飛距離を
判定表示する装置は公知であるが、従来の装置は
特殊マツトを用いてヘツドの打球領域における速
度と軌跡を検知するものであり、演算装置を含む
大掛りな表示装置を必要とし専ら業務用であつて
個人では使用し得ないものであつた。 Devices that determine and display the direction and distance of a ball during golf ball hitting practice are well known, but the conventional device uses a special mat to detect the velocity and trajectory of the ball in the ball hitting area of the head, and requires a large amount of equipment including a calculation device. It required a large display device and was intended for business use only and could not be used by individuals.
本案は、永久磁石を埋設したボールとクラブ自
体に検知器と判定発音表示装置を内蔵したゴルフ
練習クラブとからなり、このクラブは、ヘツド部
分に複数の感応コイルとグリツプ部分に電源と判
定装置を具備し外部装置を使用しないことを特徴
とするものである。 The proposed golf practice club consists of a ball with a permanent magnet embedded in it, and a golf practice club with a built-in detector and judgment sound display device built into the club itself. It is characterized in that it does not require any external equipment.
以下に本案練習具の構成を図について説明す
る。 The configuration of the proposed practice tool will be explained below with reference to the drawings.
１はゴルフクラブ、２はヘツド本体であつてウ
ツドクラブの形状を有しており鉄以外の金属又は
木製或は合成樹脂製である。３は表面板であり、
その背後の前記本体内にスイートスポツト４を中
心として３個乃至５個の検出用誘導コイル５ａ，
５ｂ，５ｃ……が埋設されている。これらのコイ
ルは相互干渉を防ぐため必要に応じて電磁的遮蔽
が施される。 1 is a golf club, and 2 is a head body having the shape of a wood club and made of metal other than iron, wood, or synthetic resin. 3 is the surface plate;
Behind the body, there are three to five detection induction coils 5a centered around the sweet spot 4,
5b, 5c... are buried. These coils are electromagnetically shielded as necessary to prevent mutual interference.
６はシヤフトであつて、グリツプ部分７には電
池８、スイツチ８ａ、判定回路９、及びブザー１
０が内蔵されている。 6 is a shaft, and the grip portion 7 includes a battery 8, a switch 8a, a judgment circuit 9, and a buzzer 1.
0 is built-in.
判定回路９は、各コイルに接続１１された増巾
器及び所定時間（２〜５秒）だけだけ個有の周波
数で発振する発振回路とから構成されている。 The determination circuit 9 includes an amplifier 11 connected to each coil and an oscillation circuit that oscillates at a unique frequency for a predetermined period of time (2 to 5 seconds).
２０はボールであつて固定枢軸２３を中心とし
て回転自在なアーム２１に取付けられており、打
球面側に永久磁石２２が埋設されている。 A ball 20 is attached to an arm 21 that is rotatable around a fixed pivot 23, and a permanent magnet 22 is embedded in the ball hitting surface side.
上記構成の練習具において打球するとボール中
の磁石とヘツド中のコイルとの短時間（約500μ
ｓ）、近接によつて誘導電流を生ずる。 When you hit a ball with the above-mentioned practice tool, the magnet in the ball and the coil in the head interact for a short time (approximately 500μ).
s), producing an induced current due to proximity.
この場合ボールとヘツドとの当接点に最も近い
コイルからの発生電圧が大きいから各コイルに対
応する発振器の周波数を規定しておくことによ
り、当接点を知ることができる。例えばコイル５
ａにはＡ〔Hz〕、コイル５ｂにはＢ〔Hz〕……と
いうようにしておくことによつて練習者はクラブ
を振りながら打球位置を知り、直ちに己ずからス
タンス、グリツプ等を矯正してストレートボール
を打つようにすることができるのである。 In this case, since the voltage generated from the coil closest to the point of contact between the ball and the head is large, the point of contact can be determined by specifying the frequency of the oscillator corresponding to each coil. For example, coil 5
By setting A [Hz] to a, B [Hz] to coil 5b, etc., the practitioner knows the hitting position while swinging the club, and immediately corrects his/her stance, grip, etc. This allows the ball to be hit straight.
また打球点は、球筋と関係があるからこれによ
つてスライス、フツク等の打ち分け練習も可能に
なる。 Also, since the hitting point is related to the ball's trajectory, it is possible to practice hitting the ball in different ways, such as slicing or hooking.
本案においてコイルに発生する誘導電流はボー
ル当接の場合の他、ボール反撥の場合にも発生す
るからボールが当つた点と離れた点が異なるとき
はブザー１０からは２以上の混合振動音を発生す
るので、これによつてもスライス、フツク等の飛
球状態を推測することも可能である。 In this case, the induced current generated in the coil occurs not only when the ball contacts the ball, but also when the ball rebounds, so when the point where the ball hits and the point where it leaves the ball are different, the buzzer 10 generates a mixed vibration sound of two or more vibrations. Since this occurs, it is also possible to infer fly ball conditions such as slices and hooks based on this.
