전술한 바와 같은 종래기술의 로킹장치를 갖춘 신발에서는, 섬유질의 신발끈은 탄성이 없으므로, 신발이 착용자의 발에 고착되도록 신발을 세게 조이면 착용자는 발등에 심한 압박감을 느낄 수 있다. 또는, 반대로 신발을 약하게 조이면 신발이 쉽게 벗겨질 수도 있다. 또한, 섬유질의 신발끈이 로킹장치에 고정된 후에 신발끈이 신장되지 않으므로, 신발은 조여진 그대로 유지되어 착용자는 불편함을 느낄 수 있다. 그러므로, 압박감을 주지 않으면서 신발과 같은 물품을 적절한 세기로 조여주고 그러한 조임 상태를 유지할 수 있는 장치가 필요하다.In the shoe with the locking device of the prior art as described above, since the fibrous shoelace is not elastic, if the shoe is tightened tightly so that the shoe is fixed to the wearer's foot, the wearer may feel a great pressure on the foot. Or, on the contrary, weakly tightening the shoe may cause the shoe to come off easily. In addition, since the shoelaces are not stretched after the fibrous shoelaces are fixed to the locking device, the shoes can remain untightened and the wearer may feel uncomfortable. Therefore, there is a need for a device that can tighten articles such as shoes to an appropriate strength and maintain such tightness without applying pressure.
또한, 전술한 종래기술의 로킹장치는 섬유질의 신발끈을 돌기에 대고 누르기 위해 피니언을 가압하도록 구성되어 있어서 그 구조가 복잡하고, 매끈한 신발끈과 피니언 사이에 미끄러짐이 발생할 수 있다. 그러므로, 간단한 구조로 끈을 신속하고 신뢰성 높게 로킹할 수 있는 장치가 필요하다.In addition, the above-described locking device of the prior art is configured to press the pinion to press the fibrous shoelace against the projection so that the structure is complicated, and slipping may occur between the smooth shoelace and the pinion. Therefore, there is a need for a device that can lock a string quickly and reliably with a simple structure.

The push pin 134 may function as a part that a user can press when moving the buckle of the locking position to the unlocking position.
버클(130)을 버클하우징(120) 내로 결합시킬 때, 블록체(133)는 가이드돌기(132)의 경사면(132a)으로부터 버클하우징(120)의 통로(120a)로 삽입된다. 경사면(132a)이 프레임플레이트(123a, 123b)의 하단을 지나면서 프레임플레이트(123a, 123b)는 외측으로 약간 팽창한다. 가이드돌기(132)가 가이드슬롯(122)에 끼워지면 프레임플레이트(123a, 123b)는 원상태로 복귀하면서, 버클(130)이 통로(120a) 내에 유지된다. 가이드돌기(132)가 가이드슬롯(122)에 끼워져 블록체(133)가 통로(120a) 내에서 이동할 때, 가이드돌기(132)의 수직면(132b)이 가이드슬롯(122)의 하단에 맞닿음으로써 버클(130)의 버클하우징(120)로부터의 이탈이 방지된다.When the buckle 130 is coupled into the buckle housing 120, the block body 133 is inserted into the passage 120a of the buckle housing 120 from the inclined surface 132a of the guide protrusion 132. As the inclined surface 132a passes through the lower ends of the frame plates 123a and 123b, the frame plates 123a and 123b slightly expand outwardly. When the guide protrusion 132 is inserted into the guide slot 122, the frame plates 123a and 123b are returned to their original states, and the buckle 130 is maintained in the passage 120a. When the guide protrusion 132 is fitted into the guide slot 122 and the block body 133 moves in the passage 120a, the vertical surface 132b of the guide protrusion 132 abuts against the lower end of the guide slot 122. Departure from the buckle housing 120 of the buckle 130 is prevented.
탄성스트링(110)은 로킹핀(121)의 둘레에 걸어진 상태에서 조임방향(FD)으로 당겨지거나 신장될 수 있다. 조임방향(FD)은 로킹핀(121)을 중심으로 하여 탄성스트링(110)의 상측부분(110a)과 탄성스트링(110)의 하측부분(110b)이 예각을 이루면서 놓일 때 물품을 조이기 위해 탄성스트링(110)이 이동하는 방향이다(도 3 참조). 탄성스트링(110)이 조임방향(FD)으로 당겨지거나 신장됨에 따라, 버클하우징(120)은 상기 물품 쪽으로 밀착되고 신장되는 탄성스트링(110)에 의해 물품은 조여지게 된다. 조임방향(FD)의 이동시, 탄성스트링(110)의 환돌기(111)는 래칫돌기(131)를 버클하우징(110)의 상단 측으로(제2 방향으로) 민다. 따라서, 버클(130)은 로킹해제위치로 이동되거나 로킹해제위치에 유지될 수 있다. 탄성스트링(110)이 어느 정도 당겨지거나 신장된 상태에서 해제되면(예컨대, 사용자가 탄성스트링(110)을 버클하우징(110)로부터 조임방향(FD)으로 당긴 후 놓으면), 물품의 조임 또는 묶음 상태를 유지하도록 탄성스트링(110)을 고정하기 위해, 탄성스트링(110)은 자체의 탄성 또는 수축성에 의해 수축방향(CD)(탄성스트링(110)이 어느 정도의 수축력으로 물품에 밀착되는 방향)으로 이동하거나 수축한다. 수축방향(CD)의 이동시, 탄성스트링(110)의 환돌기(111)는 래칫돌기(131)를 버클하우징(110)의 하단 측으로(제1 방향으로) 밀어서 버클(130)을 로킹위치로 이동시킨다.The elastic string 110 may be pulled or extended in the tightening direction FD in a state of being walked around the locking pin 121. The tightening direction FD is an elastic string for tightening the article when the upper portion 110a of the elastic string 110 and the lower portion 110b of the elastic string 110 are placed at an acute angle with respect to the locking pin 121. This is the direction in which 110 moves (see FIG. 3). As the elastic string 110 is pulled or stretched in the tightening direction FD, the buckle housing 120 is tightened by the elastic string 110 which is in close contact with the article and stretched. In the movement of the tightening direction FD, the ring protrusion 111 of the elastic string 110 pushes the ratchet protrusion 131 toward the upper side of the buckle housing 110 (in the second direction). Thus, the buckle 130 can be moved to the unlocked position or held at the unlocked position. When the elastic string 110 is released in a stretched or stretched state to some extent (eg, when the user pulls the elastic string 110 from the buckle housing 110 in the tightening direction (FD) and releases it), the article is tightened or bundled. In order to fix the elastic string 110 to maintain the elastic string 110, the elastic string 110 by its elasticity or shrinkage in the shrinking direction (CD) (the direction in which the elastic string 110 is in close contact with the article with a certain amount of shrinking force). Move or contract. In the movement of the retraction direction CD, the ring protrusion 111 of the elastic string 110 pushes the ratchet protrusion 131 toward the lower side of the buckle housing 110 (in the first direction) to move the buckle 130 to the locking position. Let's do it.
도 3, 도 8 및 도 9를 참조하여, 이 실시예에 따른 버클장치(100)에 있어서의 탄성스트링의 로킹 및 로킹해제의 예를 설명한다.3, 8, and 9, an example of locking and unlocking of the elastic string in the buckle device 100 according to this embodiment will be described.
탄성스트링(110)이 래칫돌기(131)와 로킹핀(121)의 사이에서 구속 없이 이동가능한 상태 또는 이동이 불가능한 상태에서, 사용자는 탄성스트링(110)의 일단부를 잡고서 조임방향(FD)으로 잡아 당긴다. 그러면, 탄성스트링(110)은 로킹핀(121)의 둘레를 돌아서 조임방향(FD)으로 이동하고, 버클하우징(120)은 물품 쪽으로 밀착된다. 탄성스트링(110)의 이동에 의해 물품이 어느 정도 조여지고 버클하우징(120)이 물품에 밀착되고나서, 탄성스트링(110)을 더 잡아 당기면, 탄성스트링(110)은 그 길이방향에서 신장한다. 이러한 이동과 신장의 과정에서, 버클하우징(120)은 물품에 밀착되고 탄성스트링(110)은 신장된 상태에서 물품을 조이게 된다. 또한, 탄성스트링의 환돌기(111)가 래칫돌기(131)를 버클하우징(120)의 상단 측으로(즉, 제1 방향으로) 밀게 되므로, 버클(130)은 환돌기(111)의 밈 또는 부딪힘에 의해 도 8에 도시하는 로킹해제위치(즉, 로킹핀(121)과 래칫돌기(131)의 사이에서 탄성스트링(110)에 구속이 가해지지 않는 버클(130)의 위치)로 이행하거나 로킹해제위치에 유지된다. 이 경우, 가이드돌기(132)의 경사면(132a)이 가이드슬롯(122)의 상단에 걸리므로, 버클(130)이 버클하우징(120)으로부터 분리되는 것이 방지된다.In the state where the elastic string 110 is movable or restrained without restriction between the ratchet protrusion 131 and the locking pin 121, the user grasps one end of the elastic string 110 and holds it in the tightening direction (FD). Pull. Then, the elastic string 110 is moved around the locking pin 121 in the tightening direction (FD), the buckle housing 120 is in close contact with the article. After the article is tightened to some extent by the movement of the elastic string 110 and the buckle housing 120 is brought into close contact with the article, the elastic string 110 is stretched further, and the elastic string 110 extends in the longitudinal direction thereof. In the process of movement and stretching, the buckle housing 120 is in close contact with the article and the elastic string 110 is tightened in the stretched state. In addition, since the ring protrusion 111 of the elastic string pushes the ratchet protrusion 131 toward the upper side of the buckle housing 120 (that is, in the first direction), the buckle 130 may meme or collide with the ring protrusion 111. 8 to the unlocking position shown in FIG. 8 (that is, the position of the buckle 130 without restraining the elastic string 110 between the locking pin 121 and the ratchet protrusion 131) or unlocking. Is kept in position. In this case, since the inclined surface 132a of the guide protrusion 132 is caught by the upper end of the guide slot 122, the buckle 130 is prevented from being separated from the buckle housing 120.
물품을 어느 정도 조인 후에 신장된 탄성스트링(110)이 해제되면(또는 사용자가 탄성스트링(110)을 놓으면), 탄성스트링(110)은 자체의 탄성 또는 수축성에 의해 수축방향(CD)으로 이동하면서 로킹핀(121)을 돌아 나간다. 이러한 수축 이동시, 탄성스트링(110)의 환돌기(111)가 래칫돌기(131)에 부딪혀 래칫돌기(131)를 버클하우징(120)의 하단 측으로(즉, 제1 방향으로) 밀게 되고, 버클(130)은 이러한 밈 또는 부딪힘에 의해 통로(120a) 내에서 버클하우징(120)의 하단 측으로 강하게 이동된다. 래칫돌기(131)가 로킹핀(121) 부근에 위치하면, 래칫돌기(131)를 밀고 있는 환돌기(111)의 하측에 있는 탄성스트링(110)의 로킹부분(110c)이 로킹핀(121)에 접촉 또는 밀착된다. 이 경우, 탄성스트링(110)의 수축력이 계속 작용하고 있고 래칫돌기(131)에는 그에 접촉하고 있는 환돌기(111)에 의해 버클하우징(120)의 하단 측을 향하는 힘이 계속 작용하고 있다. 로킹위치에 있어서, 래칫돌기(131)와 로킹핀(121) 사이의 최단거리는 자유상태의 로킹부분(110c)의 두께보다 작다. 따라서, 탄성스트링의 로킹부분(110c)은 밀려 들어오는 래칫돌기(131)에 의해 로킹핀(121) 쪽으로 어느 정도 압축되면서 로킹핀(121)과 래칫돌기(131) 사이에 끼이게 된다. 이러한 끼임에서 기인하는 로킹부분(110c)을 로킹핀(121)과 래칫돌기(131)의 사이에 유지시키는 힘이 탄성스트링(110)의 수축력보다 커지게 되면, 도 9에 도시하는 로킹위치와 같이, 로킹부분(110c)은 로킹핀(121)과 래칫돌기(131)의 사이에 정지하게 되고 탄성스트링(110)은 래칫돌기(131)와 로킹핀(121)의 사이에 고정 또는 로킹된다.When the stretched elastic string 110 is released (or the user releases the elastic string 110) after tightening the article to some extent, the elastic string 110 moves in the shrinking direction (CD) by its elasticity or shrinkage. Exit the locking pin 121. During this contraction movement, the annular protrusion 111 of the elastic string 110 hits the ratchet protrusion 131 and pushes the ratchet protrusion 131 toward the lower side of the buckle housing 120 (that is, in the first direction), and the buckle ( 130 is strongly moved to the bottom side of the buckle housing 120 in the passage (120a) by such a meme or hit. When the ratchet protrusion 131 is located near the locking pin 121, the locking portion 110c of the elastic string 110 under the ring protrusion 111 pushing the ratchet protrusion 131 is locked by the locking pin 121. Is in contact with or in close contact with In this case, the contracting force of the elastic string 110 continues to act, and the force toward the lower end side of the buckle housing 120 continues to act on the ratchet protrusion 131 by the ring protrusion 111 contacting it. In the locking position, the shortest distance between the ratchet protrusion 131 and the locking pin 121 is smaller than the thickness of the locking portion 110c in the free state. Accordingly, the locking portion 110c of the elastic string is sandwiched between the locking pin 121 and the ratchet protrusion 131 while being compressed to some extent by the ratchet protrusion 131 that is pushed toward the locking pin 121. When the force holding the locking portion 110c resulting from such pinching between the locking pin 121 and the ratchet protrusion 131 becomes greater than the contracting force of the elastic string 110, as shown in the locking position shown in FIG. The locking portion 110c is stopped between the locking pin 121 and the ratchet protrusion 131, and the elastic string 110 is fixed or locked between the ratchet protrusion 131 and the locking pin 121.
한편, 가이드슬롯(122)과 가이드돌기(132)의 위치 관계에 의해 탄성스트링(110)의 로킹이 달성될 수도 있다. 즉, 래칫돌기(131)가 환돌기(111)에 의해 밀려서 로킹핀(121)에 근접하면, 래칫돌기(131)가 탄성스트링(110)의 로킹부분(110c)을 로킹핀(121)에 대고 압박하고 있고 탄성스트링(110)은 수축방향(CD)으로 수축력을 계속 발생시키고 있다. 이러한 위치에서, 래칫돌기(131)에 의해 압축되고 있는 로킹부분(110c)이 탄성스트링(110)의 수축력 하에서도 로킹핀(121)을 벗어나지 않도록, 가이드돌기(132)가 가이드슬롯(122)의 하단에 맞닿게 가이드슬롯(122)과 가이드돌기(132)의 위치가 정해질 수도 있다.Meanwhile, the locking of the elastic string 110 may be achieved by the positional relationship between the guide slot 122 and the guide protrusion 132. That is, when the ratchet protrusion 131 is pushed by the ring protrusion 111 to approach the locking pin 121, the ratchet protrusion 131 places the locking portion 110c of the elastic string 110 on the locking pin 121. The elastic string 110 continues to generate contraction force in the contracting direction CD. In this position, the guide protrusion 132 of the guide slot 122 so that the locking portion 110c being compressed by the ratchet protrusion 131 does not leave the locking pin 121 even under the contracting force of the elastic string 110. The position of the guide slot 122 and the guide protrusion 132 may be determined to abut the bottom.

Further, a pair of extension portions 333b extending in the second direction are formed at both ends in the longitudinal direction of the block body 333. When the block body 333 moves in the buckle housing 320, the connecting pin 324 of the buckle housing 320 is placed between the pair of extensions 333b. In addition, the block body 333 has concave grooves 333a at both ends in the longitudinal direction facing the locking pin 121. The concave groove 333a extends to the side facing the locking pin 121 of the extension portion 333b. An elastic string 110 is positioned between the concave groove 333a of the block body 333 and the locking pin 121. The above-described guide protrusion 332 is formed on the surface of the block body 333 facing the frame plates 323a and 323b.

The ratchet protrusion 331 is located in the concave groove 333a of the block body 333. The ratchet protrusion 331 is configured similarly to the ratchet protrusion 131 in the first embodiment.
누름핀(334)은 블록체(333)의 하단으로부터 하방으로(제1 방향으로) 연장되어 있다. 누름핀(334)은 로킹위치의 버클을 로킹해제위치로 이동시킬 때 사용자가 누를 수 있는 부분으로 기능할 수 있다.The push pin 334 extends downwardly (in the first direction) from the lower end of the block body 333. The push pin 334 may function as a part that a user can press when moving the buckle of the locking position to the unlocking position.
버클(330)은 버클하우징(320) 내로 끼움에 의해 유지될 수 있다. 예컨대, 제1 실시예의 버클장치(100)와 유사하게, 가이드돌기(332)가 프레임플레이트(323a, 323b)의 하단으로부터 가이드슬롯(322)에 끼워지는 식으로 버클(330)이 버클하우징(320)에 결합될 수 있다. 버클(330)이 버클하우징(320) 내에서 이동할 때, 가이드돌기(332)의 수직면(332b)이 가이드슬롯(322)의 하단에 맞닿음으로써 버클(330)의 버클하우징(320)으로부터의 하방 이탈이 방지된다. 또한, 블록체(333)의 수평부(333b)의 상단이 연결핀(323)에 맞닿음으로써 버클(330)의 버클하우징(320)으로부터의 상방 이탈이 방지된다. 가이드슬롯(322)의 하단의 위치는 탄성스트링(110)의 로킹핀(121)에 로킹되는 부분이 래칫돌기(331)에 의해 로킹핀(121)에 압축되도록 또는 래칫돌기(331)가 로킹핀(121)을 지나서 로킹핀(121)보다 버클하우징(320)의 하측으로 이동하지 않도록 정해져 있다. Buckle 330 may be held by fitting into buckle housing 320. For example, similar to the buckle device 100 of the first embodiment, the buckle 330 buckle housing 320 in such a way that the guide protrusion 332 is fitted to the guide slot 322 from the lower end of the frame plate (323a, 323b). ) May be combined. When the buckle 330 moves within the buckle housing 320, the vertical surface 332b of the guide protrusion 332 abuts against the lower end of the guide slot 322, thereby lowering the buckle 330 from the buckle housing 320. Departure is prevented. In addition, the upper end of the horizontal portion 333b of the block body 333 abuts against the connecting pin 323, thereby preventing upward deviation from the buckle housing 320 of the buckle 330. The position of the lower end of the guide slot 322 is such that the portion locked to the locking pin 121 of the elastic string 110 is compressed to the locking pin 121 by the ratchet protrusion 331 or the ratchet protrusion 331 is a locking pin. It is determined not to move beyond the locking pin 121 to the lower side of the buckle housing 320 beyond the 121.
도 13, 도 18 및 도 19를 참조하여, 이 실시예에 따른 버클장치(300)에 있어서의 탄성스트링의 로킹 및 로킹해제의 예를 설명한다.13, 18, and 19, an example of locking and unlocking of the elastic string in the buckle device 300 according to this embodiment will be described.
탄성스트링(110)이 래칫돌기(331)와 로킹핀(121)의 사이에서 구속 없이 이동가능한 상태 또는 이동이 불가능한 상태에서, 탄성스트링(110)이 조임방향(FD)으로 당겨지면, 탄성스트링(110)은 로킹핀(121)의 둘레를 돌아서 조임방향(FD)으로 이동하고, 버클하우징(320)은 물품 쪽으로 밀착된다. 물품이 어느 정도 조여진 후 탄성스트링(110)을 더 잡아 당기면, 탄성스트링(110)은 그 길이방향에서 신장한다. 이러한 이동과 신장의 과정에서, 탄성스트링의 환돌기(111)가 래칫돌기(331)를 버클하우징(320)의 상단 측으로(즉, 제2 방향으로) 밀게 되므로, 버클(330)은 환돌기(111)의 밈 또는 부딪힘에 의해 도 18에 도시하는 로킹해제위치로 이행하거나 로킹해제위치에 유지된다. 이 경우, 블록체(333)의 상단 부분이 연결핀(324)에 걸리므로, 버클(330)이 버클하우징(320)으로부터 분리되는 것이 방지된다.When the elastic string 110 is pulled in the tightening direction FD in a state in which the elastic string 110 is freely movable or cannot be moved between the ratchet protrusion 331 and the locking pin 121, the elastic string ( 110 is moved around the locking pin 121 in the tightening direction (FD), the buckle housing 320 is in close contact with the article. After the article is tightened to some extent and the elastic string 110 is pulled further, the elastic string 110 extends in the longitudinal direction thereof. In the course of the movement and stretching, the elastic projection ring protrusion 111 pushes the ratchet protrusion 331 to the upper side of the buckle housing 320 (that is, in the second direction), the buckle 330 is a ring protrusion ( By the memes or bumps of 111), the transition to the unlocking position shown in Fig. 18 is maintained at the unlocking position. In this case, since the upper portion of the block 333 is caught by the connecting pin 324, the buckle 330 is prevented from being separated from the buckle housing 320.
그 후 탄성스트링(110)이 해제되면, 탄성스트링(110)은 자체의 탄성 또는 수축성에 의해 수축방향(CD)으로 이동하면서 로킹핀(121)을 돌아 나간다. 이러한 수축 이동시, 탄성스트링(110)의 환돌기(111)가 래칫돌기(331)에 부딪혀 래칫돌기(331)를 버클하우징(320)의 하단 측으로(즉, 제1 방향으로) 밀게 되고, 버클(330)은 이러한 밈 또는 부딪힘에 의해 통로(320a) 내에서 버클하우징(320)의 하단 측으로 강하게 이동된다. 래칫돌기(331)가 로킹핀(121)의 부근에 위치하면, 래칫돌기(331)를 밀고 있는 환돌기(111)의 하측에 있는 탄성스트링(110)의 로킹부분(110c)이 로킹핀(121)에 접촉 또는 밀착된다. 이 때, 래칫돌기(331)에는 탄성스트링(110)의 수축력과 그에 접촉하고 있는 환돌기(111)에 의해 버클하우징(320)의 하단 측을 향하는 힘(버클(320)을 제1 방향으로 이동시키는 힘)이 계속 작용하고 있다. 또한, 로킹위치에 있어서, 래칫돌기(331)와 로킹핀(121) 사이의 최단거리는 자유상태의 로킹부분(110c)의 두께보다 작다. 따라서, 탄성스트링의 로킹부분(110c)은 래칫돌기(331)에 의해 로킹핀(121) 쪽으로 어느 정도 압축되면서 로킹핀(121)과 래칫돌기(331) 사이에 끼이게 된다. 도 19에 도시된 바와 같이, 이러한 끼임에 의해 로킹부분(110c)은 로킹핀(121)과 래칫돌기(331)의 사이에 정지하게 되고 탄성스트링(110)은 로킹핀(121)의 대하여 고정 또는 로킹된다.Then, when the elastic string 110 is released, the elastic string 110 moves out of the locking pin 121 while moving in the shrinking direction (CD) by its elasticity or shrinkage. During this contraction movement, the annular protrusion 111 of the elastic string 110 hits the ratchet protrusion 331 and pushes the ratchet protrusion 331 toward the bottom side of the buckle housing 320 (that is, in the first direction), and the buckle ( 330 is strongly moved to the bottom side of the buckle housing 320 in the passage 320a by this memes or bumps. When the ratchet protrusion 331 is located near the locking pin 121, the locking portion 110c of the elastic string 110 at the lower side of the ring protrusion 111 pushing the ratchet protrusion 331 is locked pin 121. Contact or close contact with At this time, the ratchet protrusion 331 moves the force toward the bottom side of the buckle housing 320 (buckle 320) by the contracting force of the elastic string 110 and the annular protrusion 111 in contact with the ratchet protrusion 331 in the first direction. Force) continues to work. Further, in the locking position, the shortest distance between the ratchet protrusion 331 and the locking pin 121 is smaller than the thickness of the locking portion 110c in the free state. Therefore, the locking portion 110c of the elastic string is sandwiched between the locking pin 121 and the ratchet protrusion 331 while being compressed to some extent by the ratchet protrusion 331 toward the locking pin 121. As shown in FIG. 19, the locking portion 110c is stopped between the locking pin 121 and the ratchet protrusion 331 by the pinching, and the elastic string 110 is fixed or fixed to the locking pin 121.

The insertion part 533 includes a cylindrical body so as to correspond to the cross-sectional shape of the guide passage 523. The insertion part 533 is in contact with the inner surface (first guide surface) of the flange portion 525 and the surface (second guide surface) facing the guide passage 523 of the stepped portion 527, and the guide passage 523. Are inserted with some play. The outer surface 533a of the insertion portion 533 is in contact with the inner surface of the flange portion 525. Surfaces 533b at both edges of the insertion portion 533 are in contact with the surface of the stepped portion 527. The connecting piece 534 has a concavely curved shape with respect to the buckle 530 when viewed from the front, and also concave along its longitudinal direction. The connecting piece 534 may function as a part that can be grabbed by the user when the buckle of the locking position is moved to the unlocking position.
버클(530)은 로킹핀(121)에 면하는 표면 상에, 즉 반원통체의 삽입부(533)의 내면 상에 래칫(ratchet)돌기(531)를 가진다. 래칫돌기(531)는 삽입부(533)의 상기 제1 방향에서의 단부(또는 하단) 부근에 위치되어 있다. 래칫돌기(531)는 전술한 실시예에서의 래칫돌기와 동일하게 구성되어 있다.The buckle 530 has a ratchet protrusion 531 on the surface facing the locking pin 121, that is, on the inner surface of the insertion portion 533 of the semi-cylindrical body. The ratchet protrusion 531 is located near the end (or bottom) of the insertion portion 533 in the first direction. The ratchet protrusion 531 is configured similarly to the ratchet protrusion in the above-described embodiment.
버클(530)을 버클하우징(520)에 유지시키는 요소로서 작용하는 가이드돌기(532)는 삽입부(533)의 하단 부근에서 삽입부(533)의 외면(533a) 상에 직경방향으로 형성되어 있다. 가이드돌기(532)는 삽입부(533)의 하단을 향하는 측에 경사면(532a)과 그 반대측에 수직면(532b)을 가진다.The guide protrusion 532 which acts as an element for holding the buckle 530 in the buckle housing 520 is formed in the radial direction on the outer surface 533a of the insertion part 533 near the lower end of the insertion part 533. . The guide protrusion 532 has an inclined surface 532a on the side facing the lower end of the insertion part 533 and a vertical surface 532b on the opposite side.
가이드돌기(532)가 끼워지는 가이드슬롯(522)은 버클하우징(520)의 단차부(527)에 평행하게 플랜지부(525)를 관통하여 형성되어 있다. 가이드슬롯(522)의 길이에 의해 버클(530)(및 삽입부(533))의 이동범위가 한정된다. 버클(530)을 가이드통로(523)에 삽입할 때, 삽입부(533)는 가이드돌기(532)의 경사면(532a)으로부터 가이드통로(523)로 삽입된다. 경사면(532a)이 플랜지부(525)의 상단을 지나면서 삽입부(533)는 직경방향에서 약간 압축된다. 가이드돌기(532)가 가이드슬롯(522)에 결합하면 삽입부(533)가 원상태로 복귀하면서, 버클(130)이 가이드통로(523)에 유지된다. 가이드돌기(532)가 가이드슬롯(522)에 끼워져 삽입부(533)가 가이드통로(523)를 따라 이동할 때, 가이드돌기(532)의 수직면(532b)이 가이드슬롯(522)의 상단에 맞닿음으로써 삽입부(533)의 가이드통로(523)로부터의 이탈이 방지된다.The guide slot 522 to which the guide protrusion 532 is inserted is formed through the flange portion 525 parallel to the stepped portion 527 of the buckle housing 520. The movement range of the buckle 530 (and insertion portion 533) is limited by the length of the guide slot 522. When the buckle 530 is inserted into the guide passage 523, the insertion part 533 is inserted into the guide passage 523 from the inclined surface 532a of the guide protrusion 532. As the inclined surface 532a passes the upper end of the flange portion 525, the insertion portion 533 is slightly compressed in the radial direction. When the guide protrusion 532 is coupled to the guide slot 522, the insertion portion 533 is returned to its original state, and the buckle 130 is maintained in the guide passage 523. When the guide protrusion 532 is inserted into the guide slot 522 and the insertion portion 533 moves along the guide passage 523, the vertical surface 532b of the guide protrusion 532 abuts on the upper end of the guide slot 522. As a result, separation from the guide passage 523 of the insertion portion 533 is prevented.
도 27 및 도 28을 참조하여, 이 실시예에 따른 버클장치(500)에 있어서의 탄성스트링의 로킹 및 로킹해제의 예를 설명한다.27 and 28, an example of locking and unlocking of the elastic string in the buckle device 500 according to this embodiment will be described.
래칫돌기(531)와 로킹핀(121)이 탄성스트링(110)을 구속하거나 구속하지 않는 상태에서, 탄성스트링(110)이 조임방향(FD)으로 당겨지면, 탄성스트링(110)은 로킹핀(121)의 둘레를 돌아서 조임방향(FD)으로 이동하고, 버클하우징(520)은 물품 쪽으로 밀착된다. 물품이 어느 정도 조여진 상태에서 탄성스트링(110)이 더 당겨지면, 탄성스트링(110)은 그 길이방향에서 신장한다. 이러한 이동과 신장의 과정에서, 탄성스트링의 환돌기(111)가 삽입부(533)에 형성된 래칫돌기(531)를 버클하우징(520)의 상단 측으로(즉, 제2 방향으로) 밀게 되므로, 버클(530)은 도 27에 도시하는 로킹해제위치로 이행하거나 로킹해제위치에 유지된다. 이 경우, 가이드돌기(532)의 수직면(532b)이 가이드슬롯(522)의 상단에 걸리므로, 삽입부(533)가 버클하우징(520)으로부터 분리되는 것이 방지된다.When the ratchet protrusion 531 and the locking pin 121 restrain or restrain the elastic string 110, when the elastic string 110 is pulled in the tightening direction FD, the elastic string 110 is locked pin ( The circumference of 121 is moved in the tightening direction FD, and the buckle housing 520 is in close contact with the article. If the elastic string 110 is further pulled while the article is tightened to some extent, the elastic string 110 extends in the longitudinal direction thereof. In the process of movement and extension, the elastic projection ring protrusion 111 pushes the ratchet protrusion 531 formed in the insertion portion 533 to the upper side of the buckle housing 520 (that is, in the second direction), so that the buckle 530 shifts to or remains in the unlocking position shown in FIG. In this case, since the vertical surface 532b of the guide protrusion 532 is caught by the upper end of the guide slot 522, the insertion part 533 is prevented from being separated from the buckle housing 520.
그 후 탄성스트링(110)이 해제되면, 탄성스트링(110)은 자체의 탄성 또는 수축성에 의해 수축방향(CD)으로 이동하면서 로킹핀(121)을 돌아 나간다. 이러한 수축 이동시, 탄성스트링(110)의 환돌기(111)가 래칫돌기(531)에 부딪혀 래칫돌기(531)를 버클하우징(520)의 하단 측으로(즉, 제1 방향으로) 밀게 되고, 버클(530)의 삽입부(533)는 가이드통로(523)를 따라 버클하우징(520)의 하단 측으로(즉, 제1 방향으로) 강하게 이동된다. 래칫돌기(531)가 로킹핀(121)의 부근에 위치하면, 래칫돌기(531)를 밀고 있는 환돌기(111)의 하측에 있는 탄성스트링(110)의 로킹부분(110c)이 로킹핀(121)에 접촉 또는 밀착된다. 이 경우, 래칫돌기(531)에는 탄성스트링(110)의 수축력과 그에 접촉하고 있는 환돌기(111)에 의해 제1 방향으로 이동시키는 힘이 계속 작용하고 있다. 또한, 로킹위치에 있어서, 래칫돌기(531)와 로킹핀(121) 사이의 최단거리는 자유상태의 로킹부분(110c)의 두께보다 작다. 따라서, 탄성스트링의 로킹부분(110c)은 래칫돌기(531)에 의해 로킹핀(121) 쪽으로 어느 정도 압축되면서 로킹핀(121)과 래칫돌기(531) 사이에 끼이게 된다. 도 28에 도시된 바와 같이, 이러한 끼임에 의해 로킹부분(110c)은 로킹핀(121)과 래칫돌기(531)의 사이에 정지하게 되고 탄성스트링(110)은 래칫돌기(131)와 로킹핀(521)의 사이에 고정 또는 로킹된다. 버클(530)이 로킹위치에 있을 때, 버클(530)의 삽입부(533)는 압축된 탄성스트링(110)의 가압력에 의해 가이드통로(523)의 내면 쪽으로 강하게 가압되어 있다. 이 상태에 있어서 버클(530)의 연결편(534)을 버클하우징(520)의 외측으로(즉, 제2 방향으로) 잡아당김으로써, 버클(530)은 로킹해제위치로 용이하게 이동될 수 있다.Then, when the elastic string 110 is released, the elastic string 110 moves out of the locking pin 121 while moving in the shrinking direction (CD) by its elasticity or shrinkage. During this contraction movement, the annular protrusion 111 of the elastic string 110 hits the ratchet protrusion 531 and pushes the ratchet protrusion 531 toward the lower side of the buckle housing 520 (that is, in the first direction), and the buckle ( The insertion portion 533 of 530 is strongly moved along the guide passage 523 toward the bottom side of the buckle housing 520 (ie, in the first direction). When the ratchet protrusion 531 is located near the locking pin 121, the locking portion 110c of the elastic string 110 under the ring protrusion 111 pushing the ratchet protrusion 531 is locked pin 121. Contact or close contact with In this case, the ratchet protrusion 531 continues to act in the first direction by the contracting force of the elastic string 110 and the annular protrusion 111 in contact with the ratchet protrusion 531. Further, in the locking position, the shortest distance between the ratchet protrusion 531 and the locking pin 121 is smaller than the thickness of the locking portion 110c in the free state. Therefore, the locking portion 110c of the elastic string is sandwiched between the locking pin 121 and the ratchet protrusion 531 while being compressed to a certain extent toward the locking pin 121 by the ratchet protrusion 531. As shown in FIG. 28, the locking portion 110c is stopped between the locking pin 121 and the ratchet protrusion 531 by the pinch, and the elastic string 110 is the ratchet protrusion 131 and the locking pin ( 521 is fixed or locked in between. When the buckle 530 is in the locked position, the insertion portion 533 of the buckle 530 is strongly pressed toward the inner surface of the guide passage 523 by the pressing force of the compressed elastic string 110. In this state, by pulling the connecting piece 534 of the buckle 530 outward (ie, in the second direction) of the buckle housing 520, the buckle 530 can be easily moved to the unlocked position.
