Abstract
(EN)
The present invention relates to a practice golf club in which the impact sound generated when the mobile weight in a head moves outwardly by centrifugal force during a swing and hits the inside of the head at the point of impact and the feeling transmitted to the hand of a trainee enable the trainee to judge whether or not the swing is accurately carried out. The practice golf club has a head (H) attached to an end of a shaft (S) having a grip (G) to generate an impact sound, wherein said head (H) comprises: a first body (100) coupled to the end of the shaft (S); a second body (110) having a tubular shape, both ends of which are open and which is fastened to the rear end of the first body (100) by a screw; a mobile weight (140) arranged in the second body (110); a magnet (180) which fixes the mobile weight (140) at a front end of the second body (110) by magnetic force; adjustment means for adjusting the gap between the magnet (180) and the mobile weight (140) to adjust the intensity of the magnetic force for drawing the mobile weight (140); a cap (120) fastened to a rear end of the second body (110) by a screw; and return means interposed between the cap (120) and the mobile weight (140) to return the mobile weight (140) to the original position when the mobile weight (140) momentarily moves by centrifugal force and collides against the cap (120) to generate an impact sound. The practice golf club of the present invention is advantageous in that the impact sound is generated at the accurate impact position only when the head speed required for the target flight distance of a golf ball is achieved during the swing, which enables the trainee to independently learn the degree of head speed required for the target flight distance of a golf ball.

L'invention concerne un club de golf d'entraînement, dans lequel le bruit d'impact généré lorsque la masse mobile de la tête se déplace vers l'extérieur sous l'action d'une force centrifuge pendant un élan et heurte l'intérieur de la tête au point d'impact, et la sensation transmise à la main d'une personne qui s'entraine, permet d'évaluer si le swing est exécuté précisément ou non. Le club de golf d'entraînement comprend une tête(H) fixée à l'extrémité d'un manche (S) doté d'une poignée (G) destinée à générer un bruit d'impact, ladite tête (H) comprenant: un premier corps (100) couplé à l'extrémité du manche (S) ; un second corps (110) présentant une forme tubulaire dont les deux extrémités sont ouvertes et qui est fixé à l'extrémité arrière du premier corps (100) par une vis ; une masse mobile (140) disposée dans le second corps (110) ; un aimant (180) qui fixe la masse mobile (140) à l'extrémité avant du second corps (110) au moyen d'une force magnétique ; des moyens de réglage destinés à régler l'espace entre l'aimant (180) et la masse mobile (140) pour régler l'intensité de la force magnétique destinée à la masse mobile (140) ; un capuchon (120) attaché à l'extrémité arrière du second corps (110) par une vis ; et des moyens de renvoi interposés entre le capuchon (120) et la masse mobile (140) pour ramener la masse mobile (140) à sa position d'origine lorsque la masse mobile (140) se déplace momentanément sous l'action d'une force centrifuge heurte le capuchon the cap (120) afin de générer un bruit d'impact. Le club de golf d'entraînement de l'invention est avantageux en ce que le bruit d'impact est produit à la position d'impact précise uniquement lorsque la vitesse de la tête requise pour que la distance de vol de la cible d'une balle de golf soit réalisée pendant l'élan, ce qui permet à la personne qui s'entraine d'apprendre indépendamment le degré de vitesse de la tête requis pour la distance de vol de la cible d'une balle de golf.

본 발명은 스윙 동작시 헤드 내부의 이동추가 원심력에 의해 밖으로 이동하여 임펙트 시점에서 헤드 내부를 타격하여 발생하는 충격음과 손에 전달되는 느낌을 감지하여 정확한 스윙이 이루어졌는지를 알 수 있는 연습용 골프채에 관한 것이다. 본 발명의 구성은 그립(G)을 갖는 샤프트(S) 단부 부착되어 스윙동작에 의해 타격음을 내는 헤드(H)를 갖는 것에 있어서, 상기 헤드(H)는, 상기 샤프트(S)의 끝 부분에 결합하는 제1몸체(100)와; 양단이 관통된 관 체로 형상을 이루면서 상기 제1몸체(100) 후미부에 나사 결합하는 제2몸체(110)와; 상기 제2몸체(110) 내부에 이동 가능하게 설치되는 이동추(140)와; 자력으로 상기 제2몸체(110)의 선단부에 상기 이동추(140)를 고정하는 자석(180)과; 상기 자석(180)과 이동추(140)의 간격을 조절하여 이동추(140)를 끌어당기는 자력의 세기를 조절하는 조절수단과; 상기 제2몸체(110)의 후단부에 나사 결합되는 캡(120)과; 상기 캡(120)과 이동추(140) 사이에 설치되어 원심력에 의해 순간적으로 이동하여 상기 캡(120)에 충돌하여 충격음이 발생하면 이를 복귀시키는 복귀수단; 으로 구성한다. 스윙동작 시 목표하는 비거리에 필요한 헤드 스피드가 이루어졌을 때만 정확한 임펙트 위치에서 타격음이 발생하기 때문에 연습자 스스로 원하는 비거리에 필요한 헤드 스피드 감을 몸으로 체득할 수가 있는 장점이 있다.
