그러면 본 발명이 제1 실시예의 끈 조절장치는 도 5에 도시한 모양과 같이 조립될 수 있다. 도 5는 끈 조절장치의 권취모드 상태를 도시한 도면이고, 도 19는 끈 조절장치의 권취모드에서 해제모드로 이동하는 과정이며, 도 20은 끈 조절장치가 해제모드로 이동된 상태이다.Then, the strap adjusting device of the first embodiment of the present invention can be assembled as shown in FIG. 5. 5 is a view showing a state of the winding mode of the strap adjustment device, FIG. 19 is a process of moving from the winding mode of the string adjustment device to the release mode, and FIG. 20 is a state in which the string adjustment device is moved to the release mode.
먼저, 사용자가 끈 조절장치를 이용하여 보빈(700)에 끈을 감는 상태를 설명한다. 도 5에 도시한 바와 같이, 노브(600)의 구동기어부(613)는 보빈(700)의 피동기어부(701)와 치합된 상태를 유지한다. 다시 말하면, 노브(600)의 구동기어부(613)의 기어치(617)는 보빈(700)의 피동기어부(701)의 기어치에 치합된다. 즉, 끈 조절장치는 권취 모드 상태가 된다. First, a state in which the user winds the string on the bobbin 700 using the string adjusting device will be described. As shown in FIG. 5, the driving gear portion 613 of the knob 600 maintains a meshed state with the driven gear portion 701 of the bobbin 700. In other words, the gear value 617 of the driving gear portion 613 of the knob 600 is meshed with the gear value of the driven gear portion 701 of the bobbin 700. That is, the string adjusting device is in a winding mode.
그리고 노브(600)의 역회전방지부(611)는 제2 하우징(400)의 역회전방지암부(409)에 결합된 상태가 된다. 다시 말하면, 노브(600)의 역회전 방지부(611)의 기어치(615)는 제2 하우징(400)의 역회전방지암부(409)의 기어치(413)에 치합된다. 이때 제2 하우징(400)의 역회전방지암부(409)는 제2 하우징(400)의 공간부(411)에 의해 축과 나란한 방향으로 이동된 상태를 유지한다.And the reverse rotation preventing portion 611 of the knob 600 is in a state coupled to the reverse rotation preventing arm portion 409 of the second housing 400. In other words, the gear value 615 of the reverse rotation preventing portion 611 of the knob 600 is engaged with the gear value 413 of the reverse rotation preventing arm portion 409 of the second housing 400. At this time, the anti-rotation arm portion 409 of the second housing 400 maintains a state moved in a direction parallel to the axis by the space portion 411 of the second housing 400.
노브(600)는 노브(600)의 역회전 방지부(611)와 제2 하우징(400)의 역회전방지암부(409)가 치합된 상태를 유지하여 역회전이 방지된다. The knob 600 maintains a state in which the anti-rotation portion 611 of the knob 600 and the anti-rotation arm portion 409 of the second housing 400 are meshed to prevent reverse rotation.
이러한 상태에서 사용자가 끈을 조일 필요가 있는 경우, 노브(600)를 일방향으로 회전시킨다. 그러면 보빈(700)은 노브(600)의 회전에 의해 함께 회전하면서 끈이 보빈(700)의 기둥부(703)에 감긴다. 그리고 끈 기둥부(703)에 감긴 후에 사용자가 노브(700)의 회전을 멈추어도 노브(600)의 역회전 방지부(611)와 제2 하우징(400)의 역회전방지암부(409)가 치합된 상태를 유지하여 끈의 장력이 유지된다. 즉, 끈이 풀리는 방향의 회전이 제한된다.In this state, when the user needs to tighten the string, the knob 600 is rotated in one direction. Then, the bobbin 700 is rotated together by rotation of the knob 600, and the string is wound around the pillar portion 703 of the bobbin 700. And even if the user stops the rotation of the knob 700 after being wound on the string pillar part 703, the anti-rotation part 611 of the knob 600 and the anti-rotation arm part 409 of the second housing 400 engage. The string tension is maintained by maintaining the condition. That is, rotation in the direction in which the string is released is limited.
이와 같이 보빈(700)이 회전할 때, 보빈(700)은 회전축 돌기부(715)가 베이스(200)의 회전축 홈부(213)에 끼워져 회전축 돌기부(715)를 중심으로 안정적인 회전을 한다. 또한, 보빈(700)이 회전할 때, 보빈(700)은 회전 가이드 돌출부(717)가 베이스(200)의 회전가이드 홈부(211)에 삽입된 상태를 유지하면서 회전한다. 따라서 보빈(700)은 축과 나란한 방향으로 유격이 발생하여도 회전 중에 자세를 유지하여 안정적인 회전을 하면서 큰 힘을 받는 끈을 조일 수 있다. When the bobbin 700 is rotated as described above, the bobbin 700 has a rotation shaft protrusion 715 fitted into the rotation shaft groove 213 of the base 200 to make stable rotation around the rotation shaft protrusion 715. In addition, when the bobbin 700 rotates, the bobbin 700 rotates while maintaining the state in which the rotation guide protrusion 717 is inserted into the rotation guide groove 211 of the base 200. Therefore, the bobbin 700 can tighten the string receiving a large force while maintaining a stable posture during rotation even if a play occurs in a direction parallel to the axis.
사용자가 끈을 느슨하게 하거나 또는 끈을 풀 필요가 있을 때인 해제모드를 설명하면 다음과 같다.The release mode, which is when the user looses the string or needs to loosen the string, is as follows.
사용자가 노브(600)를 베이스(200)의 반대방향으로 당겨 이동시킨다. 그러면 노브(600)의 제2 연장부(603)에 구비된 권취결정 돌출부(609)는 제1 하우징(300)의 기준 걸림부(301)를 타고 넘어가는 상태가 된다(도 19에 도시함). 이때, 노브(600)의 제2 연장부(603)는 축의 중심으로 방사상 방향으로 변형된다. 즉, 노브(600)의 제2 연장부(603)는 탄성력을 가짐과 동시에 유격홈부(605)에 의해 자유단을 가지므로 축을 중심으로 방사상 방향으로 변형된다. The user pulls the knob 600 in the opposite direction of the base 200 to move it. Then, the winding determination protrusion 609 provided in the second extension portion 603 of the knob 600 is in a state of riding over the reference locking portion 301 of the first housing 300 (shown in FIG. 19). . At this time, the second extension portion 603 of the knob 600 is deformed in the radial direction to the center of the axis. That is, since the second extension portion 603 of the knob 600 has an elastic force and has a free end by the clearance groove portion 605, it is deformed radially around the axis.
그리고 계속해서 사용자가 노브(600)를 베이스(200)의 반대방향으로 더욱 당긴다. 그러면 노브(600)의 제2 연장부(603)에 구비된 권취결정 돌출부(609)가 제1 하우징(300)의 기준 걸림부(301)를 타고 넘어간다(도 20에 도시함). 이때, 노브(600)의 제2 연장부(603)는 탄성력에 의해 축의 중심 방향으로 원위치 된다. And the user continues to pull the knob 600 further in the opposite direction of the base 200. Then, the winding crystal protrusion 609 provided in the second extension portion 603 of the knob 600 rides over the reference locking portion 301 of the first housing 300 (shown in FIG. 20). At this time, the second extension portion 603 of the knob 600 is returned to its original position in the center direction of the shaft by an elastic force.
그러면 노브(600)의 구동기어부(613)는 보빈(700)의 피동기어부(701)에서 분리된다. 이때 노브(600)의 역회전 방지부(611)도 제2 하우징(400)의 역회전방지암부(409)에서 분리된다. 즉, 보빈(700)은 자유회전이 가능한 상태가 된다. 따라서 끈 조절장치는 해제모드가 된다. 그러면 사용자는 보빈(700)이 자유롭게 회전되므로 끈을 느슨하게 조절할 수 있다.Then, the driving gear portion 613 of the knob 600 is separated from the driven gear portion 701 of the bobbin 700. At this time, the anti-rotation portion 611 of the knob 600 is also separated from the anti-rotation arm portion 409 of the second housing 400. That is, the bobbin 700 is freely rotatable. Therefore, the string adjustment device is in the release mode. Then, the user can loosely adjust the string because the bobbin 700 rotates freely.
만일, 사용자가 노브(600)를 베이스(200)의 반대 방향으로 더욱 당기면, 노브(600)의 제1 연장부(601)에 구비된 이탈방지 대응부(607)가 제1 하우징(300)의 이탈방지부(303)에 밀착된다. 따라서 노브(600)가 제1 하우징(300)에서 이탈되는 것을 방지하고 제1 하우징(300)에 견고하게 결합된 상태를 유지할 수 있다. If, when the user further pulls the knob 600 in the opposite direction of the base 200, the departure preventing counter 607 provided in the first extension 601 of the knob 600 of the first housing 300 It is in close contact with the departure preventing portion 303. Therefore, it is possible to prevent the knob 600 from being detached from the first housing 300 and to maintain a tightly coupled state with the first housing 300.
한편, 제2 하우징(400)의 역회전방지암부(409)는 노브(600)의 역회전 방지부(611)에 치합되거나 분리될 때 역회전방지암부(409)의 측면이 제1 하우징(300)의 내벽에 밀착되어 방사상 방향으로 이동하는 것이 차단된다. 제2 하우징(400)의 역회전방지암부(409)는 단지 그의 자유단부가 축과 나란한 방향으로만 이동하고 방사상 방향으로는 이동하는 것이 제한되므로 큰 힘에 의한 파손을 줄일 수 있어 끈 조절장치의 내구성이 향상된다.On the other hand, the reverse rotation prevention arm portion 409 of the second housing 400 is the first housing 300 when the side of the reverse rotation prevention arm portion 409 is engaged or separated by the reverse rotation prevention portion 611 of the knob 600 ) Is in close contact with the inner wall and is blocked from moving in the radial direction. The anti-rotation arm portion 409 of the second housing 400 can reduce damage due to large force because the free end portion of the second housing 400 only moves in the direction parallel to the axis and moves in the radial direction. Durability is improved.
특히, 본 발명의 제1 실시예의 제2 연장부(603)는 축을 중심으로 방사상 방향으로 변형되는 탄성체로 이루어지므로 보빈(700)에 끈이 꽉차여진 상태로 감겨 있어도 원활하게 작동할 수 있다. 또한, 본 발명의 제1 실시예의 제2 연장부(603)는 축을 중심으로 방사상 방향으로 변형되는 탄성체로 이루어지므로 제한된 공간에서 보빈(700)에 끈을 감을 수 있는 부피를 증대시킬 수 있다. 따라서 본 발명의 제1 실시예의 끈 조절장치는 끈이 감겨지는 보빈(700)의 외주의 공간을 최대한 활용할 수 있어 굵은 끈도 용이하게 적용할 수 있으며 같은 굵기라도 더 많은 끈을 감을 수 있다. 그러므로 본 발명의 제1 실시예의 끈 조절장치는 다양한 제품에 적용할 수 있는 활용도를 높일 수 있다.Particularly, since the second extension part 603 of the first embodiment of the present invention is made of an elastic body deformed in a radial direction around the axis, it can operate smoothly even when the string is wound on the bobbin 700 in a full state. In addition, the second extension portion 603 of the first embodiment of the present invention is made of an elastic body that is deformed in a radial direction around an axis, so that it is possible to increase the volume of winding the string on the bobbin 700 in a limited space. Therefore, the string adjusting device of the first embodiment of the present invention can utilize the space of the outer periphery of the bobbin 700 where the string is wound to the maximum, so that a thick string can be easily applied, and even more strings of the same thickness can be wound. Therefore, the strap adjusting device of the first embodiment of the present invention can increase the utilization that can be applied to various products.
또한 본 발명의 제1 실시예의 끈 조절장치는 제2 연장부(603)의 외측에서 외부의 힘이 가해져도 제2 연장부(603)가 변형되지 않으므로 권취모드를 견고하게 유지할 수 있다. 즉, 본 발명의 제1 실시예의 끈 조절장치는 외부에서 작용하는 힘이 발생하여도 권취 상태를 안정적으로 유지하여 제품의 품질을 향상시킬 수 있다.In addition, in the strap adjusting device of the first embodiment of the present invention, even when an external force is applied from the outside of the second extension portion 603, the second extension portion 603 is not deformed, so that the winding mode can be firmly maintained. That is, the string adjusting device of the first embodiment of the present invention can improve the product quality by stably maintaining the winding state even when a force acting from the outside occurs.
