Description
본 발명은 다이얼 타입 와이어 조임장치에 관한 것으로서, 더욱 상세하게는 소형화 제작이 가능하며 와이어를 조일 때 역회전을 방지하기 위하여 구비되는 구성들 간의 접촉면적을 넓힘으로써 내구성을 향상시킨 와이어 조임장치에 관한 것이다.The present invention relates to a dial-type wire tightening device, and more particularly, to a wire tightening device that can be miniaturized and has improved durability by increasing the contact area between components provided to prevent reverse rotation when tightening a wire. will be.
일반적으로 와이어 조임장치는 다양한 물품을 조이는 데 사용되는 것으로, 여기서는 와이어 조임장치의 다양한 활용방법 중에서 발에 착용하는 신발에 적용하는 것을 기초로 설명하지만, 신발을 비롯한 모자, 벨트, 장갑, 가방, 머리 장신구 등 와이어를 이용하여 체결되는 물품에 다양하게 적용할 수 있다.In general, wire fasteners are used to tighten various items. Here, among the various utilization methods of wire fasteners, application to shoes worn on the feet is described as the basis, but shoes, hats, belts, gloves, bags, hair It can be applied in various ways to items that are fastened using wires, such as accessories.
한편, 신발은 사전적 의미로 땅을 딛고 서거나 걸을 때 발을 보호하기 위해 신는 물건을 통틀어 일컬으며, 용도에 따라 다양하게 분류되지만 대부분의 신발에는 착용하는 각 개인의 발에 잘 맞도록 조이기 위한 신발끈이 구비된다.On the other hand, shoes in the dictionary meaning are collectively referred to as items worn to protect feet when standing or walking on the ground, and are classified in various ways depending on the purpose, but most shoes have a fastener to fit the feet of each person wearing them. Shoe laces are provided.
구체적으로는 통상의 신발은 크게 상기한 신발의 상부에 착용자의 발과 발목을 감싸는 형태로 형성되는 갑피부(Upper)와, 갑피부 하측에 형성되어 착용자의 보행에 의해 가해지는 충격을 흡수하는 중창(Midsol)과, 중창 하면에 부착되어 지면과 맞닿으며 미끄러짐을 방지하고 안정적인 접지가 가능하도록 하는 밑창(Outsole)을 포함하며, 갑피부에는 발등의 쏠림을 방지하여 보호하는 설포(Tongue)가 덧대어지고, 설포의 전측에는 끈구멍이 형성되는 보강물인 구목(Eyelet stay)이 구비되며, 끈구멍에는 신발을 발에 맞도록 조절하는 와이어(Wire) 등의 신발끈(Shoelace)이 체결된다.Specifically, a normal shoe largely consists of an upper formed in the upper part of the shoe to wrap the wearer's feet and ankles, and a midsole formed on the lower part of the upper skin to absorb the shock applied by the wearer's walking It includes a midsole and an outsole that is attached to the bottom of the midsole to contact the ground to prevent slipping and enable stable grounding. An eyelet stay, which is a reinforcement in which a lace hole is formed, is provided on the front side of the tongue, and a shoelace such as a wire that adjusts the shoe to fit the foot is fastened to the lace hole.
물론, 신발은 보행 시 벗겨지지 않도록 적당한 크기로 선택하여야 하지만, 획일적인 대량 생산 방식에 의해 특정 길이와 폭으로 규격화되어 제조되기 때문에 기성 신발의 발폭은 착용자의 발폭과 정확하게 일치되기는 어렵다.Of course, shoes should be selected in an appropriate size so that they do not come off when walking, but since they are standardized and manufactured to a specific length and width by a uniform mass production method, it is difficult for the foot width of ready-made shoes to accurately match the foot width of the wearer.
따라서, 착용자는 안전하고 쾌적한 보행이 가능하도록 신발을 신은 후, 신발끈을 적절히 당겨 조임으로써 자신의 발과 신발이 밀착되도록 하며, 신발끈을 손으로 당겨 조인 후에는 매듭을 묶어 고정시켜야 한다.Therefore, after wearing shoes to enable safe and comfortable walking, the wearer needs to properly pull and tighten the shoelaces so that their feet and shoes are in close contact, and after tightening the shoelaces by hand, tie a knot to fix them.
그러나, 신발끈을 착용자의 발에 맞추어 당기기 위해서는 신발끈에 소정의 장력을 가해야 하며, 신발끈에 매듭을 묶는 작업은 비교적 섬세한 작업을 요하기 때문에 고령자나 어린이 또는 손의 움직임이 불편한 장애인들에게 불편함을 준다는 문제점이 있다.However, in order to pull the shoelace according to the wearer's foot, a certain amount of tension must be applied to the shoelace, and tying a knot on the shoelace requires relatively delicate work. There is a problem that causes discomfort.
이러한 문제점을 해소하기 위하여, 신발에 신발끈을 일일히 결속하지 않고 간편하게 조이고 푸는 와이어 조임장치를 적용하여 신발을 신고 벗을 때 편리함을 제공하고 있다.In order to solve this problem, a wire fastener is applied to easily tighten and loosen the shoelace without binding the shoelace to the shoe, providing convenience when putting on and taking off the shoe.
한국등록특허 제10-1438572호(와이어 조임장치)에 개시된 바와 같이, 래칫기어를 사용하여 와이어 형태의 신발끈이 권취되는 보빈을 스토퍼유닛에 의해 구속하도록 이루어져 회전커버를 일방향으로 회전시키면 와이어를 조일 수 있도록 하고, 래칫을 제어한 스토퍼 유닛의 구속 상태를 해제하면 보빈의 회전이 자유로워짐에 따라 신발끈을 풀 수 있도록 형성된다.As disclosed in Korean Patent Registration No. 10-1438572 (Wire Tightening Device), the bobbin on which the wire-shaped shoelace is wound is restrained by the stopper unit using a ratchet gear, and when the rotating cover is rotated in one direction, the wire is tightened. When the restraint state of the stopper unit that controls the ratchet is released, the bobbin is free to rotate, so that the shoelace can be unfastened.
이와 같은 구성으로 이루어진 종래의 와이어 조임장치는 일방향으로 회전하는 래칫기어를 스토퍼유닛의 포올에 의해 반대방향으로 회전되는 것을 구속하면서 릴에 와이어를 감는 것이므로 래칫기어에 구속력이 강하게 편중되는 바, 예를 들어 사용자가 신발의 끈을 강하게 조이거나 발의 움직임에 의해 신발끈이 강하게 당겨질 때 역으로 신발끈은 풀리려는 힘이 강하게 작용하므로 래칫기어의 회전을 구속하는 포올에 힘이 편중되면서 래칫기어에 강한 스트레스를 주게 되므로 래칫기어와 포올이 쉽게 파손되고 마모되는 등 내구성이 저하되어 수명이 단축되는 문제점이 있었다.Since the conventional wire tightening device having such a configuration winds the wire on the reel while restraining the ratchet gear rotating in one direction from being rotated in the opposite direction by the pawl of the stopper unit, the binding force is strongly biased to the ratchet gear. For example, For example, when the user tightens the shoelace strongly or the shoelace is strongly pulled by the movement of the foot, the force to untie the shoelace is strong, so the force is concentrated on the pawl that restricts the rotation of the ratchet gear, causing strong stress on the ratchet gear. Since the ratchet gear and pawl are easily damaged and worn, durability is deteriorated and life is shortened.
또한, 신발의 끈을 조일 때 회전커버를 여러번 회전시켜 조이게 되는데, 회전커버를 회전시키다가 놓게 될 때, 회전커버와 함께 회전하는 스토퍼유닛의 스토퍼가 래칫기어에 정확하게 치합되지 않는 경우가 발생하여 스토퍼가 신발끈을 조이고자 하는 그 위치의 래칫기어보다 밀려 뒤에 있는 래칫기어에 치합됨으로써 희망하는 조임력 보다 느슨해진 상태로 조여지게 되는 문제점이 있었다.In addition, when tightening the shoe laces, the rotating cover is rotated several times to tighten it. When the rotating cover is rotated and then released, the stopper of the stopper unit rotating together with the rotating cover may not be correctly engaged with the ratchet gear, resulting in a stopper There was a problem that the shoelace was tightened in a looser state than the desired tightening force by being pushed away from the ratchet gear at the position where the shoelace was to be tightened and engaged with the ratchet gear at the back.
이를 해결하기 위하여, 한국등록특허 제10-1833680호(신발끈 조임장치)는 신발끈을 조일 때 역회전을 방지하는 메인래칫기어와 스토퍼에 이의 치합을 보조하는 보조래칫기어를 설치하여 메인래칫기어에 편중되는 작동부하를 분산시킴으로써 기어의 마모나 파손을 방지하여 사용수명을 향상시키며, 스토퍼 유닛을 유격이 있도록 결합하여 메인래칫기어에 스토퍼가 정확하게 치합되도록 함으로써 신발끈이 조임 과정에서 풀리지 않도록 한 신발끈의 조임장치에 관한 기술을 공지한 바 있으나, 장치를 소형화할 경우, 각 구성들의 크기 및 형상 축소로 인한 상호 간의 유기적 결합력이 약화되어 내구성 저하가 발생할 수 있으며, 특히, 일방향으로 회전시키기 위해 제공되는 구속력이 저하될 수 있어 구성요소의 설계 변경이 불가피해진다.In order to solve this problem, Korean Patent Registration No. 10-1833680 (shoelace tightening device) installs a main ratchet gear that prevents reverse rotation when tightening the shoelace and an auxiliary ratchet gear that assists their engagement with the stopper, so that the main ratchet gear By distributing the operating load that is biased on the gear, it prevents wear or damage of the gear to improve its service life, and by combining the stopper unit with a gap, the stopper is precisely meshed with the main ratchet gear, so that the shoelace does not come loose during the tightening process. Although technology related to a string tightening device has been known, when miniaturizing the device, the organic bonding force between each component is weakened due to the size and shape reduction of each component, which may cause a decrease in durability. In particular, it is provided to rotate in one direction. The restraining force may be lowered, and thus the design change of the component is unavoidable.

It is to provide a dial-type wire tightening device capable of preventing wear or damage of gears by distributing the load and improving durability by increasing the binding force between components.
본 발명의 또 다른 목적은 착용자에게 파지 공간을 제공하며, 조임장치를 하방으로 누르되 중심을 누르도록 할 수 있게 하여 조임장치의 상승 혹은 하강 동작이 용이한 다이얼 타입 와이어 조임장치를 제공하는 것이다.Another object of the present invention is to provide a dial-type wire tightening device that provides a gripping space to the wearer and allows the tightening device to be pressed downward while pressing the center so that the lifting or lowering operation of the tightening device is easy.

도 3은 본 발명의 바람직한 실시예에 따른 다이얼 타입 와이어 조임장치의 릴부와 중간커버를 도시한 전개사시도이다.3 is an exploded perspective view showing a reel unit and an intermediate cover of a dial-type wire tightening device according to a preferred embodiment of the present invention.
상기 와이어 조임장치의 역방향 회전을 방지하기 위하여 상기 기어부(22) 및 상기 대응기어부(45)의 상호결합을 통해 상기 릴부(20)에 구속력을 제공하는 것은 이미 많은 선행기술에 개시된 바 있으나, 상기 와이어 조임장치가 소형화될수록 구성들의 크기 및 형상 축소로 인해 상기 기어부(22) 및 상기 대응기어부(45)의 결합 또는 분리를 위한 충분한 공간 확보가 어려우며, 특히, 상기 톱니(23) 및 상기 대응톱니(43)의 크기 감소로 인해 구조적 정밀성이 요구되기 때문에 상호간의 유기적 결합력이 약화되어 일방향으로 회전시키기 위해 제공되는 구속력이 저하될 수 있으므로 본 발명의 다이얼 타입 와이어 조임장치는 도 3에 도시된 바와 같이, 상기 기어부(22) 내측에 상기 대응기어부(45)가 삽입되어 결합되되, 상기 톱니(23) 및 상기 대응톱니(43)가 2단 구조를 가지도록 함으로써 상호 간의 접촉면적을 증대시켜 결속력을 높일 수 있도록 한다.Providing a restraining force to the reel part 20 through mutual coupling of the gear part 22 and the corresponding gear part 45 in order to prevent reverse rotation of the wire tightening device has already been disclosed in many prior arts, As the wire tightening device is miniaturized, it is difficult to secure sufficient space for coupling or separation of the gear part 22 and the corresponding gear part 45 due to the size and shape reduction of the components. In particular, the teeth 23 and the Since structural precision is required due to the reduction in the size of the corresponding teeth 43, the organic bonding force between them is weakened and the binding force provided to rotate in one direction may be lowered, so the dial-type wire tightening device of the present invention is shown in FIG. As such, the corresponding gear portion 45 is inserted and coupled to the inside of the gear portion 22, and the contact area between the teeth 23 and the corresponding teeth 43 is increased by having a two-stage structure. so as to increase bonding strength.
구체적으로는, 상기 톱니(23)는 원통형상의 상기 기어부(22)의 상면에 형성되되, 상기 기어부(22) 상단부에 내주면을 따라 형성된 래칫치형톱니부(23a)와, 상기 기어부(22) 하단부 내주면을 따라 형성되며 상기 래칫치형톱니부(23a)로부터 일체로 연장되어 중심축을 향해 하방으로 경사지게 형성된 베벨치형톱니부(23b)를 구비한다.Specifically, the teeth 23 are formed on the upper surface of the cylindrical gear part 22, the ratchet toothed part 23a formed along the inner circumferential surface of the upper end of the gear part 22, and the gear part 22 ) It is formed along the inner circumferential surface of the lower end and has a bevel toothed toothed portion 23b integrally extending from the ratchet toothed portion 23a and inclined downward toward the central axis.
또한, 상기 대응톱니(43)는 상기 톱니(23)에 대응하는 형상을 가지며, 바람직하게는 원통형상을 가지는 상기 대응기어부(45)의 상단부 외주면을 따라 형성된 래칫치형대응톱니부(43a)와, 원추형상을 가지는 상기 대응기어부(45)의 하단부 외주면을 따라 형성되되, 상기 래칫치형대응톱니부(43a) 선단으로부터 일체로 연장되어 중심축을 향해 경사지게 형성된 베벨치형대응톱니부(43b)를 구비한다.In addition, the corresponding teeth 43 have a shape corresponding to the teeth 23, preferably have a ratchet type corresponding teeth portion 43a formed along the outer circumferential surface of the upper end of the corresponding gear portion 45 having a cylindrical shape and , It is formed along the outer circumferential surface of the lower end of the corresponding gear portion 45 having a conical shape, and is provided with a bevel tooth type corresponding tooth portion 43b integrally extending from the front end of the ratchet tooth type corresponding tooth portion 43a and inclined toward the central axis. do.
따라서, 상기 래칫치형톱니부(23a)와 상기 래칫치형대응톱니부(43a)가 상호 대응 결합됨과 동시에 상기 베벨치형톱니부(23b)와 상기 베벨치형대응톱니부(43b)가 상호 대응 결합됨으로써, 상기 톱니(23)와 상기 대응톱니(43)의 접촉면적이 단순히 상기 래칫치형톱니부(23a)와 상기 래칫치형대응톱니부(43a)만 결합된 경우보다 넓어지므로 마찰력이 증가하여 상기 릴부(20)에 작용하는 구속력을 극대화시킬 수 있으며, 더 나아가 상기 래칫기어(34) 및 상기 대응래칫기어(54)에 편중되는 부하를 분담하여 상기 래칫기어(34) 및 상기 대응래칫기어(54)의 마모율을 감소시켜 수명을 연장시킬 수 있는 효과를 제공하는 것이다.Therefore, the ratchet toothed portion 23a and the ratchet toothed corresponding toothed portion 43a are coupled to each other and at the same time the bevel toothed toothed portion 23b and the bevel toothed toothed portion 43b are coupled to each other in correspondence with each other, Since the contact area between the teeth 23 and the corresponding teeth 43 is wider than in the case where only the ratchet-type teeth 23a and the ratchet-type corresponding teeth 43a are simply combined, the frictional force increases, thereby increasing the reel part 20 ) can be maximized, and furthermore, the wear rate of the ratchet gear 34 and the corresponding ratchet gear 54 is shared by sharing the load biased on the ratchet gear 34 and the corresponding ratchet gear 54. It is to provide the effect of prolonging the life by reducing the
또한, 상기 톱니(23)와 상기 대응톱니(43)의 접촉면적이 넓어짐에 따라, 상기 기어부(22)와 상기 대응기어부(45)의 분리 시, 적은 거리의 이동에도 톱니 간의 간섭 없이 쉽게 분리시킬 수 있다.In addition, as the contact area between the teeth 23 and the corresponding teeth 43 increases, when the gear part 22 and the corresponding gear part 45 are separated, it is easy to move without interference between the teeth even when moving a small distance. can be separated.
도 4는 본 발명의 바람직한 실시예에 따른 다이얼 타입 와이어 조임장치의 릴부와 스토퍼유닛이 상호 결합된 상태를 도시한 단면도이며, 도 5는 본 발명의 바람직한 실시예에 따른 다이얼 타입 와이어 조임장치의 릴부와 스토퍼유닛이 상호 분리된 상태를 도시한 단면도이다.Figure 4 is a cross-sectional view showing a state in which the reel part and the stopper unit of the dial-type wire tightening device according to a preferred embodiment of the present invention are mutually coupled, Figure 5 is the reel part of the dial-type wire tightening device according to a preferred embodiment of the present invention It is a cross-sectional view showing a state in which the and the stopper unit are mutually separated.
도 4 및 도 5에 도시된 바와 같이, 상기 와이어 조임장치는 먼저 상기 하부커버(10)를 신발의 갑피에 재봉한 상태에서, 상기 수용홈(16)에 상기 릴부(20)를 장착하여 상기 와이어(70)의 양단부를 상기 릴부(20)의 인입공(26, 27)으로 삽입 결속하고, 상기 하우징부(30)를 상기 하부커버(10)에 끼워 고정시키며, 이의 상부에 상기 스토퍼유닛(50)을 안치시킨 상기 중간커버(40)를 결합시키되, 상기 걸림턱(21)에 상기 제1 걸림편(41)과 상기 제2 걸림편(51)이 걸려 상기 릴부(20)와 상기 스토퍼유닛(50)이 결합되도록 하며, 이와 동시에 상기 래칫기어(34)에 상기 스토퍼유닛(50)의 상기 대응래칫기어(54)가 치합되도록 한 다음, 상기 중간커버(40)의 중심에 위치하는 대응기어부(45)를 상기 릴부(20)의 기어부(22)에 삽입시킨 후 상기 중간커버(40)와 일체가 되도록 결합하고, 이의 외면에 상부커버(60)를 덮어 결합함으로써 조임장치가 신발에 간단하게 조립된다.As shown in FIGS. 4 and 5, the wire tightening device first attaches the reel part 20 to the receiving groove 16 in a state in which the lower cover 10 is sewn to the upper of the shoe, so that the wire Both ends of 70 are inserted and bound into the inlet holes 26 and 27 of the reel part 20, and the housing part 30 is inserted into and fixed to the lower cover 10, and the stopper unit 50 ) is placed, the middle cover 40 is coupled, and the first locking piece 41 and the second locking piece 51 are caught on the locking jaw 21, so that the reel part 20 and the stopper unit ( 50) is engaged, and at the same time, the corresponding ratchet gear 54 of the stopper unit 50 is engaged with the ratchet gear 34, and then the corresponding gear portion located at the center of the intermediate cover 40 After inserting (45) into the gear part 22 of the reel part 20, it is coupled to be integral with the middle cover 40, and the upper cover 60 is covered and coupled to the outer surface of the fastening device to the shoe. are assembled
이때, 인입공(26,27)과 인출공(26a, 27a) 및 매듭공(25)에 와이어(70)가 삽입과 권취되는 것에 대하여는 후술하도록 한다.At this time, insertion and winding of the wire 70 into the inlet holes 26 and 27, the outlet holes 26a and 27a, and the knot hole 25 will be described later.
이와 같이 조립된 상기 와이어 조임장치의 작동 방법을 설명하면, 상기 상부커버(60)가 결합된 상기 중간커버(40)의 상승 혹은 하강 동작에 따라 상기 스토퍼유닛(50)이 상기 릴부(20)와 결속 혹은 분리됨으로써 상기 릴부(20)가 상기 와이어(70)를 감거나 풀리게 한다.Referring to the operating method of the wire tightening device assembled as described above, the stopper unit 50 moves with the reel part 20 according to the upward or downward motion of the middle cover 40 to which the upper cover 60 is coupled. By binding or separating, the reel part 20 winds or unwinds the wire 70 .
구체적으로는, 우선 상기 와이어(70)를 권취할 경우, 상기 스토퍼유닛(50)의 스토퍼(52)가 상기 하우징부(30)의 상기 래칫기어(34)와 분리된 상태에서 외력을 가하여 상기 상부커버(60)를 하방으로 가압하면, 상기 상부커버(60)와 일체로 결합된 상기 중간커버(40)의 대응기어부(45)가 상기 릴부(20)의 기어부(22)에 삽입되어 상기 톱니(23)가 상기 대응톱니(43)와 서로 맞물리게 된다.Specifically, when the wire 70 is first wound, an external force is applied while the stopper 52 of the stopper unit 50 is separated from the ratchet gear 34 of the housing part 30 to When the cover 60 is pressed downward, the corresponding gear part 45 of the middle cover 40 integrally coupled with the upper cover 60 is inserted into the gear part 22 of the reel part 20, The teeth 23 mesh with the corresponding teeth 43.
또한, 상기 중간커버(40)에 안착된 상기 스토퍼유닛(50)이 상기 중간커버(40)와 함께 하강하여 제1 걸림편(41)과 제2 걸림편(51)이 상기 릴부(20)의 기어부(20) 외주면을 따라 밀려 내려가 탄성에 의해 걸림턱(21)에 걸리게 되어 상기 릴부(20)와 상기 중간커버(40)와 상기 스토퍼유닛(50)이 상호 결합되며, 이와 동시에 상기 스토퍼(52)의 단부 즉, 상기 대응래칫기어(54)가 상기 개구(47)를 통과하여 상기 하우징부(30) 내주연에 형성된 상기 래칫기어(34)와 일방향 회전하도록 치합 상태를 유지하게 된다.In addition, the stopper unit 50 seated on the intermediate cover 40 descends together with the intermediate cover 40 so that the first locking piece 41 and the second locking piece 51 are of the reel part 20. It is pushed down along the outer circumferential surface of the gear unit 20 and is caught by the locking jaw 21 by elasticity, so that the reel unit 20, the intermediate cover 40, and the stopper unit 50 are coupled to each other, and at the same time, the stopper ( 52), that is, the corresponding ratchet gear 54 passes through the opening 47 and maintains a meshed state so as to rotate in one direction with the ratchet gear 34 formed on the inner periphery of the housing part 30.
이 상태에서 상기 상부커버(60)를 일방향으로 회전시키면, 상기 상부커버(60)와 일체로 결합된 상기 중간커버(40)의 회전에 의하여 상기 스토퍼유닛(50)에 형성된 대응래칫기어(54)가 상기 하우징부(30)의 래칫기어(34)와 맞물려 일방향으로 회전하게 되며, 상기 스토퍼유닛(50)과 결합된 상기 릴부(20)가 상기 스토퍼유닛(50)과 함께 일방향으로 회전됨으로써 상기 와이어(70)가 상기 릴부(20) 외주면에 권취되는데, 이때, 상기 중간커버(40)의 대응기어부(45)와 상기 릴부(20)의 기어부(22)의 결합으로 상기 톱니(23)와 상기 대응톱니(43)의 치합으로 상기 릴부(20)가 일방향으로만 회전하도록 구속상태를 유지하게 된다.In this state, when the upper cover 60 is rotated in one direction, the corresponding ratchet gear 54 formed on the stopper unit 50 by the rotation of the middle cover 40 integrally coupled with the upper cover 60 is engaged with the ratchet gear 34 of the housing part 30 and rotates in one direction, and the reel part 20 coupled with the stopper unit 50 is rotated in one direction together with the stopper unit 50, so that the wire 70 is wound on the outer circumferential surface of the reel unit 20, and at this time, the gear unit 45 of the intermediate cover 40 and the gear unit 22 of the reel unit 20 are coupled to the teeth 23 and Due to the meshing of the corresponding teeth 43, the reel part 20 maintains a constrained state so as to rotate only in one direction.
따라서, 상기 상부커버(60)를 회전시키면 상기 와이어(70)가 연속적으로 릴부(20)에 권취되어 인장력에 의해 신발을 조일 수 있게 되고, 상기 와이어(70)가 조여진 상태에서 상기 상부커버(60)의 회전을 정지시켜도 상기 래칫기어(34)와 대응래칫기어(54), 상기 톱니(23)와 상기 대응톱니(43)가 각각 서로 맞물려 상기 릴부(20)가 반대방향으로 회전되는 것을 구속함으로써 상기 릴부(20)에 감긴 상기 와이어(70)가 풀리지 않고 긴장 상태로 조임을 유지하게 되는 것이다.Therefore, when the upper cover 60 is rotated, the wire 70 is continuously wound around the reel part 20 so that the shoe can be tightened by a tensile force, and the upper cover 60 Even if the rotation of the ) is stopped, the ratchet gear 34 and the corresponding ratchet gear 54 and the teeth 23 and the corresponding teeth 43 are engaged with each other to restrain the rotation of the reel part 20 in the opposite direction. The wire 70 wound around the reel part 20 is maintained in a tight state without being released.
이와 반대로, 신발을 벗기 위해 긴장 상태로 조인 상기 와이어(70)를 느슨하게 하고자 할 때는, 상기 상부커버(60)를 상방으로 당겨올려 상기 상부커버(60)와 일체로 결합된 상기 중간커버(40)를 상승시키며, 이와 동시에 상기 래칫기어(34)와 맞물려 상기 릴부(20)를 구속하고 있는 상기 스토퍼유닛(50)도 상기 중간커버(40)와 함께 상승되면서 탄성을 갖는 상기 제1 걸림편(41)과 상기 제2 걸림편(51)이 상기 걸림턱(21)으로부터 분리됨에 따라 상기 스토퍼유닛(50)과 상기 릴부(20)의 결속이 해제될 뿐만 아니라 상기 래칫기어(34)와 대응래칫기어(54) 또한 분리되어 상기 릴부(20)의 구속상태가 해제됨으로써 상기 릴부(20)의 회전이 자유로워져 상기 와이어(70)의 일측을 잡아당기면, 상기 릴부(20)에 권취된 상기 와이어(70)가 풀리며 조임이 느슨하게 되는 것이다.Conversely, when trying to loosen the wire 70 tightened in a tense state in order to take off the shoes, the upper cover 60 is pulled upward and the middle cover 40 integrally coupled with the upper cover 60 At the same time, the stopper unit 50 engaging with the ratchet gear 34 and restraining the reel part 20 also rises together with the middle cover 40, and the first locking piece 41 having elasticity ) and the second locking piece 51 are separated from the locking jaw 21, the binding between the stopper unit 50 and the reel part 20 is released, and the ratchet gear 34 and the corresponding ratchet gear (54) In addition, when the reel unit 20 is free to rotate by being separated and the restraint state of the reel unit 20 is released, and one side of the wire 70 is pulled, the wire 70 wound around the reel unit 20 ) is released and the tightening is loosened.
도 6은 본 발명의 바람직한 실시예에 따른 스토퍼유닛이 중간커버에 결합된 상태를 도시한 평면도이다.6 is a plan view showing a state in which a stopper unit according to a preferred embodiment of the present invention is coupled to an intermediate cover.
도 6에 도시된 바와 같이, 상기 스토퍼유닛(50)이 시계방향 혹은 반시계방향으로 미세 이동이 가능하도록 래칫기어(34)와 대응래칫기어(54) 사이에 유격이 형성된다.As shown in FIG. 6, a gap is formed between the ratchet gear 34 and the corresponding ratchet gear 54 so that the stopper unit 50 can move minutely in a clockwise or counterclockwise direction.
상기 상부커버(60)를 회전시켜 상기 와이어(70)를 조일 때, 상기 스토퍼(52)의 대응래칫기어(54)가 상기 개구(47)를 통해 상기 래칫기어(34)의 골과 산을 들락날락하면서 치합되는 과정에서 상기 스토퍼(52)가 상기 래칫기어(34)의 산 부분에 위치할 경우, 탄성에 의해 뒤로 밀려나 치합되어야 하는 상기 래칫기어(34)보다 뒤쪽에 위치한 상기 래칫기어(34)에 치합되므로 원하는 조임력을 한 번에 얻을 수 없는 경우가 발생한다.When the upper cover 60 is rotated to tighten the wire 70, the corresponding ratchet gear 54 of the stopper 52 moves in and out of the valley and mountain of the ratchet gear 34 through the opening 47 When the stopper 52 is located on the mountain portion of the ratchet gear 34 in the process of being engaged while being engaged, it is pushed back by elasticity and is located behind the ratchet gear 34 to be engaged. To the ratchet gear 34 Due to meshing, the desired clamping force cannot be obtained at once.
따라서, 래칫기어(34)와 대응래칫기어(54) 사이에 유격을 형성함으로써 상기 스토퍼(52)의 대응래칫기어(54)가 좌우방향 즉, 시계방향 혹은 반시계방향으로 미세하게 유동(遊動)하면서 정확히 정위치에 치합될 수 있도록 여유시간을 제공하여 원하는 강도의 조임력으로 와이어(70)를 조일 수 있도록 하는 것이다.Therefore, by forming a gap between the ratchet gear 34 and the corresponding ratchet gear 54, the corresponding ratchet gear 54 of the stopper 52 moves finely in the left and right directions, that is, clockwise or counterclockwise. It is to provide a spare time so that it can be engaged in exactly the right position while tightening the wire 70 with a tightening force of a desired strength.
또한, 상기 스토퍼(52)와 상기 걸림편(51) 사이에 형성된 상기 유격(S)에 의해 상기 스토퍼유닛(50)의 미세한 유동이 가능해짐으로써, 동일한 위치에서 치합되는 상기 스토퍼(52)의 대응래칫기어(54) 및 상기 래칫기어(34)가 상기 와이어 조임장치의 장기간 사용으로 인해 마모가 발생하여 치합 상태가 불량해지는 문제점을 해소하는 효과를 제공할 수 있다. In addition, the fine flow of the stopper unit 50 is enabled by the gap (S) formed between the stopper 52 and the locking piece 51, so that the corresponding stopper 52 meshed at the same position The ratchet gear 54 and the ratchet gear 34 can provide an effect of solving the problem of poor engagement due to wear caused by long-term use of the wire tightening device.
더하여, 착용자가 상부커버(60)를 일방향으로 돌리되 최대로 돌려 더 이상 상부커버(60)를 돌릴 수 없는 경우, 와이어(70)의 장력으로 상기 상부커버(60)는 역방향으로 회전하려는 힘을 받게 된다.In addition, when the wearer rotates the upper cover 60 in one direction but can no longer turn the upper cover 60 by turning it to the maximum, the tension of the wire 70 causes the upper cover 60 to rotate in the reverse direction. You will receive.
이때, 상기 개구(47)의 내주연에 상기 대응래칫기어(54)가 걸리게 되어 역방향으로 회전하지 않도록 지지함으로써, 제2 걸림편(51)과 개구(47)가 역방향으로의 힘을 분담하여 상기 와이어 조임장치의 장기간 사용으로 인해 마모가 불량해지는 문제점을 해소하는 효과를 제공할 수 있다,At this time, the corresponding ratchet gear 54 is caught on the inner periphery of the opening 47 and supported so that it does not rotate in the reverse direction, so that the second locking piece 51 and the opening 47 share the force in the reverse direction, It can provide an effect of solving the problem of poor wear due to long-term use of the wire tightening device,

도 7의 (a) 내지 (c)는 본 발명의 릴부에 와이어를 매듭짓는 방법에 대한 개략도이다.Figure 7 (a) to (c) is a schematic diagram of a method of knotting a wire to the reel unit of the present invention.
도 7의 (a)와 (b)에 도시된 바와 같이, 릴부(20)에 상기 와이어(70)가 권취되는 몸체의 외주면 일측에 형성되는 인입공(26, 27)과 인출공(26a, 27a)이 구비된다.As shown in (a) and (b) of FIG. 7, the inlet holes 26 and 27 and the outlet holes 26a and 27a formed on one side of the outer circumferential surface of the body on which the wire 70 is wound around the reel part 20 ) is provided.
다시 말하여, 와이어(70)의 단부가 삽입되는 제1 인입공(26)과 와이어(70)가 빠져나오는 제1 인출공(26a)이 형성되며, 상기 제1 인출공(26a)에서 빠져나온 상기 와이어(70)는 대각방향의 경로상에 형성된 제2 인입공(27)으로 삽입된다.In other words, a first inlet hole 26 into which the end of the wire 70 is inserted and a first outlet hole 26a through which the wire 70 exits are formed. The wire 70 is inserted into the second inlet hole 27 formed on the path in the diagonal direction.
그리고, 제2 인입공(27)으로 삽입된 상기 와이어(70)는 상기 릴부(20)의 하부 일측으로 경로가 형성된 제2 인출공(27a)로 빠져나오게 된다.Then, the wire 70 inserted into the second inlet hole 27 comes out through the second outlet hole 27a formed with a path to one side of the lower part of the reel part 20 .
다음으로, 상기 제2 인출공(27a)으로 빠져나온 상기 와이어(70)는 상기 릴부(20)의 하면 일측에 형성된 매듭공(25)으로 삽입되어 고정됨으로써, 상기 와이어(70)가 매듭지어지는데 매듭공(25)의 위치와 매듭을 짓는 방법은 후술하도록 한다.Next, the wire 70 exiting through the second drawing hole 27a is inserted into the knot hole 25 formed on one side of the lower surface of the reel part 20 and fixed, so that the wire 70 is knotted. The location of the knot ball 25 and how to tie a knot will be described later.
그리고, 인입공(26, 27)과 인출공(26a, 27a) 및 매듭공(25)은 상기 릴부(20)의 중심축을 기준으로 대칭되도록 한 쌍으로 형성되어 상기 릴부(20)가 180도로 회전하여도 같은 배치를 나타낸다.In addition, the inlet holes 26 and 27, the outlet holes 26a and 27a, and the knot hole 25 are formed as a pair to be symmetrical about the central axis of the reel part 20, so that the reel part 20 rotates 180 degrees. However, it shows the same arrangement.
다시 말하여, 상기 릴부(20)의 중심축과 직각의 방향으로 관통하며 형성되는 제1 인입공(26)의 타측이 제1 인출공(26a)이며, 제1 인출공(26a)의 경로는 대각선 하방으로 형성되되, 상기 제1 인출공(26a)의 경로 끝부분에 제2 인입공(27)이 형성된다.In other words, the other side of the first inlet hole 26 formed while penetrating in a direction perpendicular to the central axis of the reel part 20 is the first outlet hole 26a, and the path of the first outlet hole 26a is The second inlet hole 27 is formed diagonally downward and at the end of the path of the first outlet hole 26a.
