Description

골프 클럽golf club
본 발명은 골프 클럽에 관한 것으로, 상세하게는 스윙 동작 중의 임팩트 시에 골프 헤드가 최대 속도로 골프공과 타격이 이루어질 수 있도록 골프 헤드의 최대 속도에서 소리가 발생하여 골퍼의 올바른 스윙 연습을 보조할 수 있는 골프 클럽에 관한 것이다.The present invention relates to a golf club, and more particularly, a sound is generated at the maximum speed of the golf head so that the golf head can hit the golf ball at the maximum speed at impact during a swing operation, thereby assisting the golfer in correct swing practice. It's about golf clubs.
일반적으로 골프 경기는 드라이버, 아이언, 퍼터 등의 클럽으로 정지된 공을 타격하여 일정 거리의 정해진 홀컵에 홀인시키는 경기로서, 독특한 재미와 함께 운동 효과 또한 뛰어나서 많은 사람들이 즐기는 스포츠 종목이다. 이와 같은 골프를 더욱 재미있게 즐기고 경기력을 높이기 위해서는 공과 클럽의 정확한 타격이 이루어져야 하며 그 기초가 되는 것이 바른 스윙 자세를 익히는 것이다.In general, a golf game is a game in which a stationary ball is hit with a club such as a driver, iron, or putter to make a hole in a predetermined hole cup at a certain distance. In order to enjoy golf more fun and improve performance, the ball and club must be hit accurately, and the foundation is to learn the correct swing posture.
일반적으로 골프 스윙 자세는 어드레스(address), 백스윙(back swing), 백스윙의 탑, 다운스윙(down swing), 임팩트(impact), 팔로스루(follow through) 및 피니쉬(finish)의 순서로 세분된다.In general, the golf swing posture is subdivided in the order of address, back swing, top of the back swing, down swing, impact, follow through and finish.
특히, 드라이브 샷 또는 티샷과 같이 골프공을 강하게 타격하여 먼 거리를 날려 보내려고 할 때는 골프 클럽을 백스윙한 이후에 임팩트 시의 속도가 매우 중요하다.In particular, when a golf ball is hit hard and blown away a long distance, such as a drive shot or a tee shot, the speed at impact after the backswing of the golf club is very important.
임팩트 과정에서의 올바른 스윙 동작은 클럽 페이스가 골프공과 직각으로 위치되도록 하는 정확한 스퀘어 각도유지와 함께 클럽 페이스가 공과 접촉하는 순간에 가장 강하고 빠른 속도로 타격을 가하는 임팩트 타이밍 조절이 요구된다. Correct swing motion in the process of impact requires precise square angle maintenance so that the club face is positioned at right angles to the golf ball, and the impact timing that applies the strongest and fastest strike at the moment the club face comes into contact with the ball is required.
이와 같이 올바른 스윙 동작을 연습하기 위하여 다양한 기술들이 제시되어 있다. 예를 들어, 대한민국등록특허공보 제10-0910724호에서는 액상 물질을 이용한 골프 클럽을 개시하고 있으며, 골프 클럽의 샤프트 내에 액상 물질이 일부 충전된 중공부가 형성되어 스윙 속도와 샤프트의 기울기에 따라서 액상 물질이 샤프트의 중공부 내에서 출렁거리는 현상을 이용하여 스윙 과정에서 발생되는 음향과 진동을 이용하여 사용자의 스윙 연습을 보조하도록 하고 있다.In order to practice the correct swing motion as described above, various techniques have been proposed. For example, Korean Patent No. 10-0910724 discloses a golf club using a liquid material, and a hollow part filled with a liquid material is formed in the shaft of the golf club, so that the liquid material depends on the swing speed and the inclination of the shaft. Using the sloshing phenomenon in the hollow part of the shaft, the sound and vibration generated during the swing process are used to assist the user in swing practice.
본 발명은 골프 헤드의 최대 스윙 속도에서 신호음이 발생되어 사용자가 신호음을 인지하여 골프 헤드와 골프공의 정확한 임팩트 시점을 교정할 수 있도록 보조할 수 있는 골프 클럽을 제공하고자 하는 것이다.An object of the present invention is to provide a golf club capable of assisting a user to correct an accurate point of impact between a golf head and a golf ball by recognizing the signal sound generated at the maximum swing speed of the golf head.
이러한 목적을 달성하기 위한 본 발명에 따른 골프 클럽은, 샤프트와, 상기 샤프트의 선단에 구비되는 헤드를 포함하는 골프 클럽에 있어서, 상기 헤드는, 내부에 중공부가 형성되고 상기 중공부 내에 자유 회동 가능하게 힌지 고정되는 회전체를 포함한다.A golf club according to the present invention for achieving this object is a golf club comprising a shaft and a head provided at the tip of the shaft, wherein the head has a hollow portion formed therein and is freely rotatable in the hollow portion It includes a rotating body that is hinged tightly.
바람직하게는, 상기 회전체는 상기 헤드의 페이스와 나란하게 힌지축이 마련되며, 보다 바람직하게는, 상기 회전체는 상기 중공부의 원위 단면에 힌지 조립된다.Preferably, the rotating body is provided with a hinge shaft parallel to the face of the head, more preferably, the rotating body is hinged to the distal end face of the hollow part.
바람직하게는, 상기 회전체는 상기 중공부를 구성하는 면과 면접촉하게 되는 타격면을 갖는 타격부를 포함한다.Preferably, the rotating body includes a striking portion having a striking surface that is in surface contact with the surface constituting the hollow portion.

본 발명의 실시예에서 제시되는 특정한 구조 내지 기능적 설명들은 단지 본 발명의 개념에 따른 실시예를 설명하기 위한 목적으로 예시된 것으로, 본 발명의 개념에 따른 실시예들은 다양한 형태로 실시될 수 있다. 또한 본 명세서에 설명된 실시예들에 한정되는 것으로 해석되어서는 아니 되며, 본 발명의 사상 및 기술 범위에 포함되는 모든 변경물, 균등물 내지 대체물을 포함하는 것으로 이해되어야 한다.Specific structural or functional descriptions presented in the embodiments of the present invention are only exemplified for the purpose of describing embodiments according to the concept of the present invention, and the embodiments according to the concept of the present invention may be implemented in various forms. In addition, it should not be construed as being limited to the embodiments described herein, and should be understood to include all modifications, equivalents, and substitutes included in the spirit and scope of the present invention.
도 1의 (a)는 어드레스 단계로부터 백스윙 및 다운스윙의 과정의 골프 클럽을 몇몇 단계로 구분하여 보여주는 도면이며, (b)와 (c)는 골프 클럽의 스윙 과정에서 클럽 헤드의 각속도와 각가속도를 보여주는 그래프로서, 톱 오프 스윙을 시작점(t=0)으로 나타낸 것이며, t1은 임팩트 시점을 표시한다.1 (a) is a view showing the golf club in the process of the backswing and downswing from the address stage divided into several stages, (b) and (c) are the angular velocity and angular acceleration of the club head during the golf club swing process. As a graph showing, the top-off swing is indicated as the starting point (t=0), and t1 is the impact point.
일반적으로 골프 클럽의 스윙 속도(ω)는 올바른 스윙 자세와 함께 비거리를 증가시키는데 매우 중요한 요인이 된다. 따라서 골퍼는 스윙 연습을 통하여 임팩트 시의 스윙 속도(ω)를 증가시키고자 노력한다.In general, the swing speed (ω) of a golf club is a very important factor in increasing the flying distance along with a correct swing posture. Therefore, golfers try to increase the swing speed (ω) at impact through swing practice.
도 1의 (b)(c)는 스윙 과정에서 클럽 헤드의 일반적인 각속도(ω)와 각가속도(
Figure PCTKR2020014833-appb-I000001
)의 패턴을 보여주고 있으며, 이를 참고하면, 이상적인 스윙 동작은 톱 오프 스윙에서 각속도(ω)가 증가하기 시작하여 클럽 헤드가 공을 가격하게 되는 시점인 임팩트 시점(t1)에서 최대 각속도(ωm)가 된 후에 각속도(ω)가 감소한다. 그러나, 초중급의 골퍼들은 임팩트 시점(t1)과 최대 각속도(ωm)가 일치하지 않는 경우가 많이 발생되며, 예를 들어, 임팩트 시점(t1) 이전에 최대 각속도(ωm)가 되거나 임팩트 시점(t1) 이후에 최대 각속도(ωm)가 된다.Figure 1 (b) (c) shows the general angular velocity (ω) and angular acceleration (
Figure PCTKR2020014833-appb-I000001
), and referring to this, the ideal swing motion is the maximum angular velocity (ω m ) at impact (t1), which is the point at which the angular velocity (ω) starts to increase in the top-off swing and the club head hits the ball. ), the angular velocity (ω) decreases. However, for beginners and intermediate golfers, the impact time (t1) and the maximum angular velocity (ω m ) often do not match, for example, the maximum angular velocity (ω m ) before the impact time (t1) or the impact time ( After t1), it becomes the maximum angular velocity (ω m ).
일반적으로 스윙 동작 중에 임팩트 순간(t1)은 그립을 통해 전달되는 그립감을 통하여 인지가 가능하나, 골프 헤드의 최대 각속도(ωm)의 타이밍은 골퍼가 정확히 인지하기가 어렵다.In general, the moment of impact t1 during a swing operation can be recognized through the feeling of grip transmitted through the grip, but it is difficult for the golfer to accurately recognize the timing of the maximum angular velocity ω m of the golf head.
본 발명은 스윙 동작 중에 최대 각속도(ωm)에서 골퍼가 쉽게 인지할 수 있는 신호음이 발생되는 골프 클럽을 제공하고자 하는 것이며, 골프 헤드 내에 관성력에 의해 자유 회동이 가능하게 축설되는 회전체를 포함한다.An object of the present invention is to provide a golf club that generates a signal sound that can be easily recognized by a golfer at the maximum angular velocity (ω m ) during a swing operation, and includes a rotating body that can be rotated freely by an inertial force in the golf head. .
이하에서는 첨부된 도면을 참조하여 본 발명에 대해 상세히 설명한다. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 4는 본 발명의 실시예에 따른 골프 클럽의 요부 구성도이다.4 is a structural diagram of a golf club according to an embodiment of the present invention.
도 4를 참고하면, 본 실시예의 회전체(130)는, 중공부(121)의 원위 단면(121b)에 힌지축(141)을 매개로 하여 힌지 조립되는 암(131)과, 암(131)의 선단에 일체로 구성되어 중공부(121)의 측면(121c)(121d)과 면접촉이 이루어지는 타격면(132a)을 갖는 타격부(132)를 포함한다. 따라서 회전체(130)는 중공부(121) 내에서 힌지축(141)에 의해 자유 회동이 가능하고, 이 과정에서 타격면(132a)과 중공부(121)의 양 측면(121c)(121d)이 면접촉하면서 타격 신호음을 발생시킨다. 참고로, 이하 설명에서 양 측면(121c)(121d)은 헤드의 진행 방향에 따라서 전방에 위치하는 측면을 '선행 측면'이라 하고, 후방에 위치하는 측면을 '후행 측면'이라고 구분할 수 있다.Referring to FIG. 4 , the rotating body 130 of this embodiment has an arm 131 hinged to the distal end surface 121b of the hollow part 121 via a hinge shaft 141 and an arm 131 . It is integrally configured at the tip of the hollow portion 121 and includes a striking portion 132 having a striking surface 132a that is in surface contact with the side surfaces 121c and 121d of the hollow portion 121 . Therefore, the rotating body 130 can freely rotate by the hinge shaft 141 in the hollow part 121, and in this process, the striking surface 132a and both sides 121c and 121d of the hollow part 121) During this interview, a hitting signal is generated. For reference, in the following description, according to the moving direction of the head, both sides 121c and 121d may be divided into a 'leading side' and a rear side as a 'trailing side'.
도 5의 (a)(b)는 본 발명의 실시예에 따른 골프 클럽의 작동 메커니즘을 설명하기 위한 도면으로, (a)는 골프 클럽의 스윙 과정에서 클럽 헤드의 각속도(ω)의 패턴을 보여주고 있으며, 이때 골프 클럽의 스윙 궤적이 180°(π)일 때 최대 각속도(ωm)가 발생되는 것을 가정한 것이다. 도 5의 (b)는 (a)와 같은 각속도 패턴의 경우에 회전체의 동작을 도시한 것이다. 참고로, 도 5의 (b)에서는 설명의 편의를 위하여 골프 클럽의 스윙 궤적을 원형으로 가정하였으며, 헤드(120)는 중공부 만을 도시하였다.5 (a) (b) is a view for explaining an operating mechanism of a golf club according to an embodiment of the present invention, (a) shows a pattern of the angular velocity (ω) of the club head in the course of swinging the golf club At this time, it is assumed that the maximum angular velocity (ω m ) occurs when the swing trajectory of the golf club is 180° (π). Figure 5 (b) shows the operation of the rotating body in the case of the angular velocity pattern as in (a). For reference, in FIG. 5B , for convenience of explanation, the swing trajectory of the golf club is assumed to be circular, and only the hollow portion of the head 120 is illustrated.
도 5의 (a)와 같이 골프 클럽의 스윙 궤적이 180°(π)일 때 최대 각속도(ωm)가 발생되는 경우에, 스윙 궤적이 180°(π) 까지는 스윙 각속도(ω)는 증가하게 되며(ω1<ωm), 각가속도(
Figure PCTKR2020014833-appb-I000002
)는 (+)이다(도 1의 (c)참고). 이때, 회전체(130)의 힌지축은 중공부의 원위 단면에 힌지 조립되어 양(+)의 각가속도가 작용하게 되므로, 상대적으로 회전체(130)의 무게중심(CM)은 반대 방향으로 관성이 작용하여 회전체(130)는 후행 측면(121d)과 접촉된 상태를 유지한다.When the maximum angular velocity ω m occurs when the swing trajectory of the golf club is 180° (π) as shown in FIG. 5 (a), the swing angular velocity ω increases until the swing trajectory is 180° (π). and (ω1<ω m ), the angular acceleration (
Figure PCTKR2020014833-appb-I000002
) is (+) (refer to (c) of FIG. 1). At this time, since the hinge shaft of the rotating body 130 is hinged to the distal end face of the hollow part, and positive angular acceleration acts, the center of gravity (CM) of the rotating body 130 is relatively inertial in the opposite direction. The rotating body 130 maintains a state in contact with the trailing side surface (121d).
한편, 스윙 궤적이 180°(π)인 경우에 스윙 각속도(ω)는 최대 각속도(ωm)에서 변곡점이 되어 각가속도(
Figure PCTKR2020014833-appb-I000003
)는 '영'이 된다((도 1의 (c)참고)). 이후 스윙 궤적의 스윙 각가속도(
Figure PCTKR2020014833-appb-I000004
)는 음(-)이 되어 회전체(130)의 힌지축은 음(-)의 각가속도가 작용하게 되므로, 스윙 궤적이 180°(π)의 변곡 지점에서 회전체(130)의 무게중심(CM)은 관성에 의해 회전체(130)는 선행 측면(121d)과 접촉하면서 타격이 이루어져 소리가 발생된다.On the other hand, when the swing trajectory is 180° (π), the swing angular velocity (ω) becomes an inflection point at the maximum angular velocity (ω m ) and the angular acceleration (
Figure PCTKR2020014833-appb-I000003
) becomes 'zero' ((refer to (c) of FIG. 1)). Then the swing angular acceleration of the swing trajectory (
Figure PCTKR2020014833-appb-I000004
) becomes negative (-) and the hinge axis of the rotating body 130 is subjected to negative (-) angular acceleration, so the swing trajectory is the center of gravity of the rotating body 130 at the inflection point of 180 ° (π) (CM) Due to the silver inertia, the rotating body 130 is hit while in contact with the preceding side surface 121d to generate a sound.
이와 같이 본 발명의 골프 클럽은 스윙 동작 중에서 최대 각속도(ωm)에서 회전체(130)에 의해 항시 일정한 소리가 발생된다. 따라서 골퍼는 이 소리를 인지하여 스윙 동작 중에 최대 각속도 타이밍을 정확히 인지할 수 있으며, 임팩트 시에 그립을 통해 인지되는 임팩트 타이밍과 최대 각속도(ωm) 타이밍에 발생되는 신호 발생 타이밍을 통하여 골프 헤드와 골프공의 정확한 임팩트 시점을 정교하게 교정할 수 있다.As described above, in the golf club of the present invention, a constant sound is always generated by the rotating body 130 at the maximum angular velocity (ω m ) during the swing operation. Therefore, the golfer can recognize this sound and accurately recognize the maximum angular velocity timing during the swing motion, and the golf head and the golf head and The precise point of impact of the golf ball can be precisely corrected.
한편, 본 실시예에서 회전체(130)는 중공부(121)의 근위 단면(121a)에 힌지 조립될 수도 있으나, 원위 단면(121b)에 힌지 조립되는 것이 바람직하다. 실질적인 골프 클럽의 스윙 동작은 원형의 궤적이 아닌 타원형의 궤적에 가까우며, 타원형의 스윙 궤적에서는 회전체에 작용하는 원심력 등으로 인하여 근위 단면(121a) 보다는 원위 단면(121b)에 힌지 조립되는 경우에 보다 신뢰성이 있게 회전체의 동작이 이루어지는 것을 확인하였다.Meanwhile, in this embodiment, the rotating body 130 may be hingedly assembled to the proximal end face 121a of the hollow part 121 , but it is preferable to be hingedly assembled to the distal end face 121b. The actual swing motion of a golf club is closer to an elliptical trajectory rather than a circular trajectory, and in the elliptical swing trajectory, due to centrifugal force acting on the rotating body, the hinge is assembled on the distal end surface 121b rather than the proximal end surface 121a. It was confirmed that the operation of the rotating body was reliably performed.
