Description

골프 스윙 연습 보조장치golf swing practice aid
본 발명은 골프 스윙 연습을 보조하는 기술에 관한 것이다.The present invention relates to a technique for assisting golf swing practice.
골프는 특히 다른 스포츠에 비하여 올바른 자세가 강조되는 운동중 하나로서, 그중에서도 가장 올바른 자세가 필요한 동작은 스윙자세이다.Golf is one of the sports in which correct posture is emphasized compared to other sports. Among them, the swing posture is the movement that requires the most correct posture.
스윙동작은 골프 스윙 시 손과 클럽헤드가 단일평면상에서 원을 그리면서 회전되는 것으로서, 프로 골퍼라 할지라도 끊임없이 연습하지 않으면 자세가 흐트러져 좋은 경기결과를 얻을 수 없으므로 스윙동작은 초보자뿐만 아니라 숙련된 골퍼에게 있어서도 강조되는 부분이다.The swing motion is when the hand and club head rotate in a circle on a single plane during the golf swing. It is also an area of emphasis.
골프 스윙은 어드레스(Address), 백스윙(Back Swing), 백스윙 탑(Back Swing Top), 다운스윙(Down Swing), 임팩트(Impact), 팔로우스루(Follow-Through), 피니쉬(Finish) 등 약 7단계로 구분된다.The golf swing has about 7 stages including Address, Back Swing, Back Swing Top, Down Swing, Impact, Follow-Through, and Finish. is divided into
백스윙 탑에서 임팩트 가기전 다운스윙을 하게 되는데, 이때 몸통이 먼저 회전하고 팔이 따라오도록 스윙을 해야 보다 정확하고 파워풀한 스윙을 할 수 있게 된다. 그런데 이렇게 몸통이 먼저회전하고 팔이 따라오는 스윙자세를 체득하는 것이 용이하지 않다.At the top of the backswing, you do a downswing before impact. At this time, you must swing so that the torso first rotates and the arms follow, so that you can make a more accurate and powerful swing. However, it is not easy to acquire a swing posture in which the body rotates first and the arms follow.
아마추어들에게 있어 보통은 백스윙 탑에서 다운스윙 시작시몸통이 먼저 회전하고 팔이 따라오는 것이 아니라, 팔과 몸통이 함께 회전하게 된다. For amateurs, when starting the downswing from the top of the backswing, the torso rotates first and the arms do not follow, but the arms and the torso rotate together.
이에, 본 발명의 발명자는 백스윙 탑에서 다운스윙시 몸통이 먼저 회전하고 팔이 따라올 수 있도록 연습할 수 있는 장치를 개발하기 위하여 오랜 연구와 고민을 거친 끝에 본 발명을 완성하기에 이르렀다.Accordingly, the inventor of the present invention has completed the present invention after a long period of research and contemplation in order to develop a device that can practice so that the torso rotates first and the arms follow during the downswing at the top of the backswing.

골프 스윙 연습시, 사용자가 백스윙 탑에서 다운스윙으로 전환할 때, 팔보다 몸통을 먼저 회전하고 팔은 몸통 회전에 의하여 따라오는 연습을 많이 해야한다. 왜냐하면 몸통이 먼저 회전해야 회전축의 흔들림없이 더 강하고, 더 정확한 임팩트를 골프공에 줄 수 있기 때문이다. In golf swing practice, when the user switches from the top of the backswing to the downswing, the user must practice a lot to rotate the body before the arm and follow the arm rotation by the body rotation. This is because, when the body rotates first, a stronger and more accurate impact can be given to the golf ball without shaking the axis of rotation.
이에 본 발명은 사용자가 스윙 연습시 몸통이 먼저 회전함을 인식하게 할 수 있도록 백스윙 탑에서 팔을 유지한 상태로 몸통을 회전하게 되면, 몸통의 회전력에 의하여 자석으로 붙어있던 부분이 떨어져 스토퍼에 부딪히면서 소리를 낼 수 있는 장치를 제공하는 것이다. Accordingly, in the present invention, when the user rotates the body while maintaining the arm at the top of the backswing so that the user can recognize that the body rotates first during swing practice, the part attached to the magnet falls off by the rotational force of the body and collides with the stopper. To provide a device capable of producing sound.
본 발명은 사용자의 다리와 팔에 각각 착용되고 골프 스윙 연습시 골프 스윙의 백스윙 탑에서 다운 스윙시 사용자의 팔보다 몸통이 먼저 회전하도록 사용자 스스로 연습할 수 있는 골프 스윙 연습 보조장치에 관한 것이다.The present invention relates to a golf swing practice assisting apparatus that is worn on a user's legs and arms, respectively, and can practice by himself so that the user's torso rotates before the user's arm during the downswing from the top of the backswing of the golf swing during golf swing practice.

도 4는 본 발명에 따른 레그유닛(100)의 동작을 개략적으로 나타낸 도면이다. 4 is a view schematically showing the operation of the leg unit 100 according to the present invention.
도 4에 도시된 바와 같이, 본 발명에 따른 레그유닛(100)은 내부의 구성들이 상하로 이동할 뿐만 아니라 본체케이스(110)도 상하이동할 수 있다. As shown in FIG. 4 , the leg unit 100 according to the present invention not only moves up and down, but also the body case 110 can move up and down.
어드레스부터 백스윙 탑, 다시 백스윙 탑에서 피니쉬까지 기본 스윙자세의 변동없이 팔의 이동이 자연스럽게 이어질 수 있도록 이에 대응하여 레그유닛(100) 내부의 구성과 본체케이스(110)가 상하로 이동될 수 있는 것이다.From address to backswing top, backswing top to finish, the internal configuration of the leg unit 100 and the body case 110 can be moved up and down in response to this so that the movement of the arm can continue naturally without any change in the basic swing posture .
도 5는 어드레스 자세에서의 레그유닛(100)의 내부를 나타낸 도면이고, 도 6은 백스윙 탑에서의 레그유닛(100)의 내부를 나타낸 도면이며, 도 7은 백스윙 탑에서 팔보다 몸통을 먼저 회전시 레그유닛(100)의 내부를 나타낸 도면이다.5 is a view showing the inside of the leg unit 100 in the address posture, FIG. 6 is a view showing the inside of the leg unit 100 in the backswing top, and FIG. 7 is the backswing top rotates the body before the arm It is a view showing the inside of the leg unit 100.
도 5 내지 도 7을 참조하여 본 발명에 따른 레그유닛(100)의 구성 및 골프 스윙 자세에 따른 레그유닛(100)의 동작을 설명한다. The configuration of the leg unit 100 according to the present invention and the operation of the leg unit 100 according to the golf swing posture will be described with reference to FIGS. 5 to 7 .
본 발명에 따른 레그유닛(100)은 본체케이스(110), 제1 자력탈착부(120), 제2 자력탈착부(130), 스토퍼(140), 메인 스프링(150), 브라켓(160), 제1 와이어(300), 제2 와이어(400)를 포함한다.The leg unit 100 according to the present invention includes a main body case 110 , a first magnetic detachment unit 120 , a second magnetic force detachable unit 130 , a stopper 140 , a main spring 150 , a bracket 160 , It includes a first wire 300 and a second wire 400 .
본체케이스(110)는 내부에 제1 자력탈착부(120), 제2 자력탈착부(130), 스토퍼(140), 메인 스프링(150), 브라켓(160), 제1 와이어(300), 제2 와이어(400)의 구성을 수용한다.The main body case 110 has a first magnetic detachable part 120, a second magnetically detachable part 130, a stopper 140, a main spring 150, a bracket 160, a first wire 300, a first magnetic force detachable part 120 therein. It accommodates the configuration of two wires 400 .
제1 자력탈착부(120)는 본체케이스(110) 내부 일단에 고정된다. 제1 탈착부에는 돌출부가 형성되고, 이러한 돌출부는 제2 자력탈착부(130)와 자력에 의하여 탈부착될 수 있다. The first magnetic detachment unit 120 is fixed to one end inside the body case 110 . A protrusion is formed in the first detachable part, and this protrusion may be detachably attached to and detached from the second magnetically detachable part 130 by magnetic force.
이렇게 제1 탈착부에 돌출부를 마련함으로써, 자력의 탈착을 용이하게 한다. 돌출부가 없다면 자력에 의하여 서로 맞닿는 면적이 커지고 이에 따라 탈착이 어려워질 수 있다. 따라서 본 발명은 자력 작용시 탈착을 용이하게 하기 위하여 자력탈착부 간의 결합에 돌출부의 구성을 포함하는 것이다.By providing the protrusion in the first detachable portion in this way, the detachment of the magnetic force is facilitated. If there is no protrusion, the area in contact with each other increases due to magnetic force, and thus detachment may be difficult. Therefore, the present invention is to include the configuration of the protrusion in the coupling between the magnetic desorption in order to facilitate the detachment when the magnetic force is applied.
제2 자력탈착부(130)는 본체케이스(110) 내부에 형성되고, 제1 자력탈착부(120)와 자력에 의하여 탈부착될 수 있다. 탈착은 외부의 힘에 의하여 부착은 자력에 의하여 이루어질 수 있다. 즉, 외부의 힘에 의하여 제1 자력탈착부(120)로부터 제2 자력탈착부(130)가 탈착되었다가 외부의 힘이 사라지면 자력에 의하여 다시 서로 부착되는 것이다.The second magnetic desorption unit 130 is formed inside the body case 110 and may be detachably attached to and detached from the first magnetic desorption unit 120 by magnetic force. Desorption may be performed by an external force, and attachment may be performed by magnetic force. That is, when the second magnetic desorption unit 130 is detached from the first magnetic desorption unit 120 by an external force, and the external force disappears, they are attached to each other again by magnetic force.
이때 외부의 힘이 바로 백스윙 탑에서의 몸통 회전력이다. 즉, 백스윙 탑에서 팔의 상태를 유지한 채로 몸통만 회전하는 순간에 이때의 몸통 회전력이 제2 자력탈착부(130)를 제1 자력탈착부(120)로부터 이탈시키는 힘으로 작용하게 되는 것이다.At this time, the external force is the torso rotational force at the top of the backswing. That is, at the moment when only the torso rotates while maintaining the state of the arms in the backswing top, the torso rotational force at this time acts as a force to separate the second magnetic desorption unit 130 from the first magnetic desorption unit 120 .
제1 자력탈착부(120)와 제2 자력탈착부(130)는 자력에 의하여 탈부착되는 것으로서, 둘 중 적어도 하나는 자석을 포함할 수 있다.The first magnetic desorption unit 120 and the second magnetic desorption unit 130 are detachable by magnetic force, and at least one of them may include a magnet.
스토퍼(140)는 본체케이스(110) 내부에 고정되어 형성되고, 제2 자력탈착부(130)가 제1 자력탈착부(120)로부터 분리되어 이동시, 이동거리를 제한하게 된다. The stopper 140 is fixedly formed inside the main body case 110 , and when the second magnetic desorption unit 130 is separated from the first magnetic desorption unit 120 and moves, the movement distance is limited.
즉, 제2 자력탈착부(130)가 제1 자력탈착부(120)로부터 탈착되어 이동하더라도 스토퍼(140)로 인하여 더 이상 이동을 할 수 없게 된다. 다만 이때, 제2 자력탈착부(130)가 이동하면서 스토퍼(140)에 부딪히게 되는데, 부딪히면서 “딱”소리를 낼 수 있고, 이러한 소리로 사용자가 몸체가 팔보다 먼저 회전함을 인지할 수 있게 된다.That is, even if the second magnetic desorption unit 130 is detached from the first magnetic desorption unit 120 and moves, it cannot move any more due to the stopper 140 . However, at this time, as the second magnetic detachment unit 130 moves, it collides with the stopper 140, and as it collides, a “click” sound can be made, and with this sound, the user can recognize that the body rotates before the arm. do.
메인 스프링(150)은 본체케이스(110) 내부에 형성되고, 제2 자력탈착부(130)와 일단이 연결된다. 메인 스프링(150)은 외부의 힘에 의하여 신축하게 되는데, 이때 메인 스프링(150)과 연결된 제2 자력탈착부(130)도 힘을 받게 된다. The main spring 150 is formed inside the body case 110 , and one end is connected to the second magnetic desorption unit 130 . The main spring 150 is expanded and contracted by an external force. At this time, the second magnetic detachment unit 130 connected to the main spring 150 also receives a force.
메인 스프링(150)을 당기는 외부의 힘이 커지면 제2 자력탈착부(130)에 전달되어 제2 자력탈착부(130)가 제1 자력탈착부(120)로부터 이탈될 수 있다.When the external force pulling the main spring 150 increases, it may be transmitted to the second magnetic desorption unit 130 so that the second magnetic desorption unit 130 may be separated from the first magnetic desorption unit 120 .
메인 스프링(150)과 제2 자력탈착부(130)는 연결부(151)에 의하여 서로 연결되고, 이러한 연결부(151)는 스토퍼(140)를 관통하도록 형성될 수 있다. 즉 스토퍼(140)에는 연결부(151)가 관통되는 관통홀이 형성되어 있다. 이에 따라서 스토퍼(140)를 중심으로 자력탈착부와 메인 스프링(150)이 양쪽에 놓이게 된다.The main spring 150 and the second magnetically detachable part 130 are connected to each other by a connection part 151 , and the connection part 151 may be formed to pass through the stopper 140 . That is, the stopper 140 has a through hole through which the connection part 151 passes. Accordingly, the magnetic detachment unit and the main spring 150 are placed on both sides of the stopper 140 as the center.
브라켓(160)은 본체케이스(110) 내부에 형성되고 메인 스프링(150)의 타단에 결합된다. 그리고 이러한 브라켓(160)에는 제1 와이어(300)가 연결되어 외부의 힘을 브라켓(160)에 전달하고, 브라켓(160)에 전달된 힘은 메인 스프링(150)에 전달되는 것이다. The bracket 160 is formed inside the body case 110 and is coupled to the other end of the main spring 150 . And the first wire 300 is connected to the bracket 160 to transmit an external force to the bracket 160 , and the force transmitted to the bracket 160 is transmitted to the main spring 150 .
제1 와이어(300)는 브라켓(160)과 암유닛(200)을 서로 연결하도록 형성될 수 있다. 팔의 회전으로 인한 암유닛(200)의 회전력이 제1 와이어(300)를 통하여 브라켓(160)에 전달되고, 브라켓(160)에 전달된 힘이 메인 스프링(150)을 거쳐 제2 자력탈착부(130)까지 전달되는 것이다.The first wire 300 may be formed to connect the bracket 160 and the arm unit 200 to each other. The rotational force of the arm unit 200 due to the rotation of the arm is transmitted to the bracket 160 through the first wire 300 , and the force transmitted to the bracket 160 is transmitted through the main spring 150 to the second magnetic detachment unit. (130) will be transmitted.
제2 와이어(400)는 일단이 연결부(151)에 결합되고, 메인 스프링(150)의 내부 및 브라켓(160)을 관통하여 연장되며, 제2 와이어(400)의 타단에는 슬리브(410)가 형서어되어 브라켓(160)의 이동거리를 제한하게 된다. The second wire 400 has one end coupled to the connection part 151 , and extends through the inside of the main spring 150 and the bracket 160 , and a sleeve 410 is formed at the other end of the second wire 400 . It serves to limit the moving distance of the bracket 160 .
팔의 회전에 의하여 제1 와이어(300)가 당겨지고, 제1 와이어(300)는 결합된 브라켓(160)을 당기게 되어 브라켓(160)을 이동시키는데, 이때 제2 와이어(400)의 슬리브(410)의 구성을 통하여 브라켓(160)이 더 이상 이동하지 않게 된다.The first wire 300 is pulled by the rotation of the arm, and the first wire 300 pulls the coupled bracket 160 to move the bracket 160, in which case the sleeve 410 of the second wire 400 is ) through the configuration of the bracket 160 no longer moves.
브라켓(160)의 이동이 제한되는 지점에서, 메인 스프링(150)의 신장도 더 이상 진행되지 않고 멈추게 된다. 이때가 사용자가 취하는 골프 스윙자세에서 백스윙 탑에 있을 때이며, 이에 대응하여 레그유닛(100)과 암유닛(200) 사이 거리를 조절할 수 있다.At a point where the movement of the bracket 160 is restricted, the extension of the main spring 150 is also stopped without further progressing. This is when the user is on the top of the backswing in the golf swing posture taken by the user, and the distance between the leg unit 100 and the arm unit 200 may be adjusted in response thereto.
이러한 구성을 통하여 사용자가 백스윙 탑의 위치를 일정하게 연습할 수 있는 효과를 볼 수도 있다.Through this configuration, the user may see the effect that the position of the backswing top can be constantly practiced.
사용자가 백스윙 탑에서 다운스윙시 팔보다 몸통을 먼저 회전하는 경우, 팔의 상태가 유지된 채로 몸통의 회전력이 전달되어 제2 자력탈착부(130)가 제1 자력탈착부(120)로부터 이탈하게 되는 것이다. 또한 제2 자력탈착부(130)가 제1 자력탈착부(120)로부터 분리되어 이동하다가 스토퍼(140)에 부딪치면서 “딱”소리를 발생시킬 수 있고, 이러한 소리로 인하여 사용자가 몸통 회전을 인지할 수 있게 된다.When the user rotates the body before the arm during the downswing at the top of the backswing, the rotational force of the body is transmitted while the state of the arm is maintained, so that the second magnetic detachable unit 130 is separated from the first magnetic detachable unit 120 . will become In addition, the second magnetic detachment unit 130 is separated from the first magnetic detachment unit 120 and while moving, it collides with the stopper 140 and generates a “click” sound. be able to do
도 5(a)는 어드레스 자세를 나타내고, 도 5(b)는 이에 따른 본체케이스(110) 내부의 메인 스프링(150) 등의 상태를 나타내고 있다. 도 5(a) 및 (b)에서 알 수 있듯이 어드레스 자세에서 본체케이스(110) 내부로 힘이 전달되지 않아, 메인 스프링(150)이 늘어나지 않고 원래의 상태로 존재한다.Fig. 5 (a) shows the address posture, and Fig. 5 (b) shows the state of the main spring 150 inside the main body case 110 according to this. As can be seen from Figs. 5 (a) and (b), the force is not transmitted to the inside of the main body case 110 in the address posture, so the main spring 150 does not stretch and remains in its original state.
도 6(a)는 백스윙으로 팔이 회전하는 자세를 나타내고, 도 6(b)는 이에 따라서 메인 스프링(150)이 신장되는 것을 나타내고 있다. 백스윙 탑까지 팔이 올라가더라도 제2 자력탈착부(130)는 제1 자력탈착부(120)에서 떨어지지 않고 붙어있게 된다.Fig. 6 (a) shows the posture in which the arm rotates in the backswing, and Fig. 6 (b) shows that the main spring 150 is extended accordingly. Even if the arm goes up to the top of the backswing, the second magnetically detachable unit 130 is attached without falling from the first magnetically detachable unit 120 .
도 7(a)는 백스윙 탑에서 팔의 상태를 유지한 채로 몸통만 먼저 회전하는 것을 나타내고, 도 7(b)는 이에 따라 제2 자력탈착부(130)가 제1 자력탈착부(120)로부터 분리되는 것을 나타내고 있다. 몸통이 먼저 회전해야만 제2 자력탈착부(130)가 제1 자력탈착부(120)로부터 탈착될 수 있고, 몸통과 팔이 함께 회전시 제2 자력탈착부(130)는 제1 자력탈착부(120)로부터 탈착되지 않는다. 7 (a) shows that only the body rotates first while maintaining the state of the arm in the backswing top, and FIG. indicates separation. The second magnetic desorption unit 130 can be detached from the first magnetic desorption unit 120 only when the body rotates first, and when the body and the arm rotate together, the second magnetic desorption unit 130 is the first magnetic desorption unit ( 120) is not desorbed.
한편, 분리된 제2 자력탈착부(130)는 이동하다가 스토퍼(140)에 부딪치면서 이동이 멈추게 되는데, 이때 부딪치면서 “딱”소리를 내게 된다. 이러한 소리로 사용자는 몸통의 회전을 인지하게 된다. On the other hand, the separated second magnetic detachment unit 130 is moved while collided with the stopper 140 to stop the movement, and at this time, a “click” sound is generated while colliding. With this sound, the user recognizes the rotation of the torso.
도 8은 임팩트 순간의 레그유닛(100)을 나타낸 도면이고, 도 9는 팔로우스루에서의 레그유닛(100)을 나타낸 도면이며, 도 10은 어드레스에서 백스윙으로 자세가 이동할 때, 본체케이스(110)에 슬라이딩 제한돌기(171)가 붙어 있는 것을 나타낸 도면이고, 도 11은 임팩트 후 팔로우스루시 본체케이스(110)와 슬라이딩 제한돌기(171)가 서로 떨어져 있는 것을 나타낸 도면이다. 8 is a view showing the leg unit 100 at the moment of impact, FIG. 9 is a view showing the leg unit 100 in the follow-through, and FIG. 10 is a body case 110 when the posture moves from address to back swing. It is a view showing that the sliding limiting protrusion 171 is attached to it, and FIG. 11 is a view showing that the main body case 110 and the sliding limiting protrusion 171 are separated from each other during the follow-through after the impact.
본 발명에 따른 골프 스윙 연습 보조장치의 레그유닛(100)은 슬라이딩 지지대(170) 및 복귀 스프링(180)을 더 포함한다.The leg unit 100 of the golf swing practice assisting device according to the present invention further includes a sliding support 170 and a return spring 180 .
슬라이딩 지지대(170)는 본체케이스(110)가 슬라이딩 이동될 수 있도록 본체케이스(110)와 결합하여 이를 지지하게 된다. 또한, 복귀 스프링(180)은 슬라이딩 이동된 본체케이스(110)에 외력이 없어지는 경우 원위치로 복귀시킬 수 있도록 본체케이스(110)와 슬라이딩 지지대(170)를 연결하게 된다.The sliding support 170 is coupled with the body case 110 so that the body case 110 can be slidably moved to support it. In addition, the return spring 180 connects the body case 110 and the sliding support 170 so that the body case 110 can be returned to its original position when the external force disappears from the body case 110 that is slidably moved.
백스윙 탑에서 레그유닛(100)과 암유닛(200) 사이의 거리보다, 임팩트 후 피니쉬의 자세에서 레그유닛(100)과 암유닛(200) 사이의 거리가 더 멀게 된다. 따라서 백스윙 탑의 자세에 대응하여 레그유닛(100)과 암유닛(200) 사이 거리가 조절되어 있으면 임팩트 후 완벽한 피니쉬를 하지 못한다. 따라서 이 경우 부족한 길이를 보충하기 위하여 본체케이스(110)가 슬라이딩 지지대(170)의 지지를 받으며 상부로 이동하는 것이다. The distance between the leg unit 100 and the arm unit 200 in the posture of the finish after impact is greater than the distance between the leg unit 100 and the arm unit 200 in the backswing top. Therefore, if the distance between the leg unit 100 and the arm unit 200 is adjusted in response to the posture of the backswing top, a perfect finish cannot be achieved after impact. Therefore, in this case, the body case 110 is supported by the sliding support 170 and moves upward in order to compensate for the insufficient length.
이때의 슬라이딩 이동거리는 백스윙 탑에서의 레그유닛(100)과 암유닛(200) 사이 거리와 피니쉬에서의 레그유닛(100)과 암유닛(200) 사이의 거리 차에 대응하도록 형성될 수 있다.At this time, the sliding movement distance may be formed to correspond to the difference between the distance between the leg unit 100 and the arm unit 200 in the top of the backswing and the distance between the leg unit 100 and the arm unit 200 in the finish.
한편, 백스윙시 본체케이스(110)는 슬라이딩 이동할 필요가 없기 때문에, 이를 제한하는 구성이 필요하다. 즉, 팔로우스루 및 피니쉬 자세에서만 본체케이스(110)의 슬라이딩 이동이 필요하기 때문에, 백스윙시에는 슬라이딩 이동을 제한하고, 팔로우스루에서는 슬라이딩 이동 제한이 해제되어야 한다.On the other hand, since the main body case 110 does not need to slide during the back swing, a configuration to limit this is required. That is, since the sliding movement of the main body case 110 is required only in the follow-through and finish postures, the sliding movement is restricted during the backswing, and the sliding movement restriction must be released in the follow-through.
이를 위하여 본 발명은 슬라이딩 제한돌기(171)를 더 포함할 수 있다.To this end, the present invention may further include a sliding limiting projection 171 .
도 8 및 도 9를 참조하면 임팩트 후 팔로우스루시 본체케이스(110)가 슬라이딩 지지대(170)의 지지를 받으며 상부로 슬라이딩 이동하는 것을 볼 수 있다.Referring to FIGS. 8 and 9 , it can be seen that the body case 110 slides upward while being supported by the sliding support 170 during the follow-through after the impact.
도 10(a)는 어드레스에서 백스윙 자세로 바뀌는 것을 나타내고,도 10(b)는 이때, 슬라이딩 제한돌기(171)가 본체케이스(110)의 슬라이딩 부를 압박하여 본체케이스(110)의 슬라이딩 이동을 제한하는 것을 나타낸다.Figure 10 (a) shows a change from the address to the back swing posture, Figure 10 (b) at this time, the sliding limiting projection 171 presses the sliding portion of the body case 110 to limit the sliding movement of the body case (110). indicates to do
백스윙시 레그유닛(100)의 반대방향으로 암유닛(200)이 이동하게 되고 이에 따라서 레그유닛(100)에는 사용자의 다리쪽으로 미는 힘이 작용하게 된다. 그 결과 슬라이딩 제한돌기(171)가 본체케이스(110)의 슬라이딩부를 압박하는 것이다. During the backswing, the arm unit 200 moves in the opposite direction to the leg unit 100 , and accordingly, a pushing force toward the user's leg is applied to the leg unit 100 . As a result, the sliding limiting projection 171 presses the sliding portion of the body case 110 .
도 11(a)는 임팩트 후 팔로우스루를 나타낸 것이고, 도 11(b)는 이 경우 레그유닛(100)과 암유닛(200)이 같은 방향에 위치하고, 따라서 본체케이스(110)를 사용자의 다리 반대쪽으로 잡아당기는 힘이 작용하여 슬라이딩 제한돌기(171)가 본체케이스(110)를 압박하지 않게 된다. Fig. 11 (a) shows the follow-through after impact, and Fig. 11 (b) shows that in this case, the leg unit 100 and the arm unit 200 are positioned in the same direction, and thus the body case 110 is placed on the opposite side of the user's leg. As a pulling force acts, the sliding limiting protrusion 171 does not press the body case 110 .
이에 따라 팔로우스루시 본체케이스(110)는 슬라이딩 이동하여 상부로 이동하고, 결국 백스윙 탑에서의 레그유닛(100)과 암유닛(200) 사이 거리와 피니쉬에서의 레그유닛(100)과 암유닛(200) 사이의 거리 차를 극복할 수 있게 된다.Accordingly, during follow-through, the body case 110 slides and moves upward, and eventually the distance between the leg unit 100 and the arm unit 200 in the backswing top and the leg unit 100 and the arm unit in the finish ( 200) can be overcome.
