Is provided.

상기 채널부(102)는 절개부(112)에 의해 중앙부(114)와 두 외측부(116)가 형성되도록 되어 있고, 상기 두 외측부(116)에 계단부(118)가 형성되고 중앙부(114)에 제2계단부(120)가 형성되어 있다. 또한, 상기 채널부(102)를 형성하는 데에 상기 절개부(112)를 사용하지 않고 중앙부(114)를 완전히 제거하여 구멍을 형성하는실시예도 개시하고 있다.The channel portion 102 is formed such that the central portion 114 and the two outer portions 116 are formed by the incision portion 112, and the step portions 118 are formed on the two outer portions 116 and the central portion 114 is formed at the center portion 114. The second staircase 120 is formed. In addition, an embodiment is disclosed in which a hole is formed by completely removing the central portion 114 without using the cutout 112 to form the channel portion 102.

상기 연장부(104)는 상기 채널부의 중앙부(114)가 형성하는 함몰된 부분으로 삽입될 수 있도록 내측밴드부(108)의 끝단부에 가늘고 길게 형성되며, 도시된 바와 같이 내측밴드부(108)와 연장부(104)의 연결부위는 직각으로 절개된 형상이다.The extension part 104 is formed to be long and thin at the end of the inner band part 108 so that the extension part 104 can be inserted into a recessed portion formed by the central part 114 of the channel part, and the inner band part 108 and the extension part as shown. The connection part of the part 104 is a shape cut at right angles.

또한, 상기 연장부(104)의 길이는 도 2 및 도 3을 참조하면 알 수 있듯이, 상기 이어부(100)를 소성 변형시키지 않고 후크(122,124)들만 결합된 가결합 상태에서 상기 채널부의 중앙부(114)로 인입되는 것이 보장될 수 있도록 충분한 길이를 가지도록 형성되어 있다.In addition, the length of the extension portion 104 can be seen with reference to Figures 2 and 3, the center portion of the channel portion in the temporary coupling state in which only the hooks (122, 124) is coupled without plastic deformation of the ear portion (100) 114) is formed to have a sufficient length so that it can be guaranteed to be drawn in.

상기 후크부(110)의 후크(122,124)들은 서포트후크(122)와 서스펜션후크 (124)로 이루어져 상기 서포트후크(122)는 클램핑 밴드의 길이방향 장력을 지지하도록 하고 상기 서스펜션후크(124)는 상기 외측밴드부(106)의 자유단이 내측밴드부 (108) 중심으로부터 어긋나지 않도록 가이드함과 아울러 내측밴드부(108)의 외측면으로부터 벌어지지 않고 밀착되도록 지지할 수 있게 되어 있다.The hooks 122 and 124 of the hook unit 110 are composed of a support hook 122 and a suspension hook 124 to support the longitudinal tension of the clamping band, and the suspension hook 124 is the support hook 122. The free end of the outer band portion 106 is guided so as not to be displaced from the center of the inner band portion 108, and can be supported to be in close contact with the outer band portion 108 without being opened from the outer surface.

그런데, 상기한 바와 같은 클램핑 밴드는 상기 채널부의 중앙부(114)로 상기 연장부(104)가 인입되는 것이 보장될 수 있도록 하기 위해 상기한 바와 같이 연장부(104)의 길이를 충분히 하여야 하므로 클램핑 밴드의 길이가 길어져 재료비 상승의 원인이 된다.By the way, the clamping band as described above should be sufficient length of the extension portion 104 as described above in order to ensure that the extension portion 104 is introduced into the central portion 114 of the channel portion, the clamping band The length of elongates, which causes an increase in the material cost.

또한, 상기 후크부의 후크들(122,124)은 상기한 바와 같이 서포트후크(122)와 서스펜션후크(124)를 별도로 구비해야하므로 후크부(110)의 전체 길이가 길어지게 되어 역시 재료비를 상승시키는 원인이 된다.In addition, since the hooks 122 and 124 of the hook portion have to be provided with the support hook 122 and the suspension hook 124 separately as described above, the overall length of the hook portion 110 becomes long, which also causes a material cost increase. do.

따라서, 본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 간단한 취급으로 원하는 체결력을 손쉽게 얻을 수 있도록 하면서도 제작하는 데에 소요되는 재료의 길이를 축소하여 제조원가를 크게 절감할 수 있도록 한 클램핑 밴드를 제공함에 그 목적이 있다.Accordingly, the present invention has been made in order to solve the above problems, the clamping band to reduce the length of the material required to manufacture while reducing the length of the material required to make it easy to obtain the desired fastening force with simple handling The purpose is to provide.

도 4 내지 도 6은 본 발명에 따른 클램핑 밴드가 가체결 되기 전의 상태를 도시한 것이고, 도 7 및 도 8은 클램핑 밴드가 가체결된 상태의 구조를 도시하고 있다.4 to 6 show the state before the clamping band is pre-tightened, and FIGS. 7 and 8 show the structure of the state where the clamping band is pre-tightened.

종래와 유사하게 본 발명에 따른 클램핑 밴드도 기본적으로 이어부(1)와 채널부(3) 및 연장부(5)를 구비하고 외측밴드부(7)와 내측밴드부(9)가 겹쳐진 부위에후크부(11)가 구비되어 있다.Similarly, the clamping band according to the present invention basically has an ear portion 1, a channel portion 3 and an extension portion 5, and a hook portion at a portion where the outer band portion 7 and the inner band portion 9 overlap. (11) is provided.

참고적으로 설명의 명확함을 위하여 이하에서 상기의 각 부분들을 구비한 단일의 클램핑 밴드를 이루는 금속띠를 "밴드(13)"라 칭하기로 한다.For reference, for clarity, the metal band constituting the single clamping band having each of the above-mentioned parts will be referred to as a "band 13".

상기 채널부(3)는 클램핑 밴드의 길이방향을 따라 형성된 두 개의 강성조절용 슬롯(15)에 의해 구분되는 중앙부(17)와 두 외측부(19), 상기 중앙부(17)에 형성된 제1계단부(21) 및 상기 연장부(5)가 채널부(3)로 인입되는 방향을 따라 좁아지도록 상기 두 외측부(19)에 각각 소정각도 경사진 상태로 형성되는 제2계단부(23)로 구성되어 있다.The channel portion 3 has a central portion 17 and two outer portions 19 separated by two rigidity adjusting slots 15 formed along the longitudinal direction of the clamping band, and a first stair portion formed at the central portion 17 ( 21 and the second staircase portion 23 formed in the inclined state at predetermined angles on the two outer portions 19 so as to narrow along the direction in which the extension portion 5 enters the channel portion 3. .

즉, 상기 제2계단부(23)의 경사는 클램핑 밴드가 가체결 상태에서 집게에 의해 완전체결 상태로 될 때 상기 연장부(5)가 진행하는 방향을 따라 좁아지는 방향으로 경사지도록 형성되어 있어서, 채널부의 중앙부(17)와 외측부(19)가 이루는 공간의 내부로 상기 연장부(5)가 쉽게 인입될 수 있도록 한 것이다.That is, the inclination of the second staircase 23 is formed to be inclined in a direction narrowing along the direction in which the extension part 5 progresses when the clamping band is fully fastened by the forceps in the pretightened state, The extension part 5 can be easily introduced into the space formed by the central part 17 and the outer part 19 of the channel part.

따라서, 상기와 같은 제2계단부(23)를 구비한 클램핑 밴드는 내측밴드부(9) 및 연장부(5)의 길이를 짧게 하여도, 가체결 상태로부터 완전체결 상태로 전환되면서 자연적으로 상기 제2계단부(23)에 의해 정확하게 내측밴드부(9)와 외측밴드부(7)의 중심선을 일치시킨 상태로 클램핑 밴드가 체결될 수 있게 한다.Therefore, the clamping band having the second step portion 23 as described above naturally converts from the pre-tightening state to the full-tightening state even if the length of the inner band part 9 and the extension part 5 is shortened. The second step 23 allows the clamping band to be fastened in a state where the center lines of the inner band part 9 and the outer band part 7 are exactly aligned.

즉, 도 7에 도시된 바와 같이 가체결 상태에서 내측밴드부의 연장부(5) 자유단이 상기 채널부의 외측부(19)와 중앙부(17)가 이루는 공간에 미리 삽입되어 있지 않아도 완전체결 상태로 될 때에 상기 제2계단부(23)의 경사에 의해 자동적으로 상기 공간으로 인입되게 되므로 재료의 절감을 위하여 내측밴드부(9) 및 연장부(5)의길이를 종래기술에 비하여 크게 줄일 수 있는 것이다.That is, in the pre-tightening state as shown in FIG. 7, the free end of the extension part 5 of the inner band part may be in the full fastening state even if it is not previously inserted in the space formed by the outer part 19 and the center part 17 of the channel part. At the time, the second step portion 23 is automatically drawn into the space due to the inclination of the inner band portion 9 and the extension portion 5 in order to reduce the material can be significantly reduced compared to the prior art.

한편, 상기 채널부의 중앙부(17)와 두 외측부(19)를 구분시키는 슬롯(15)은 상기 제2계단부(23)의 형상에 의해 국부적으로 채널부(3)의 강성이 강화되어 피체결물체에 대한 착좌 순응성이 떨어지는 것을 방지하기 위하여 클램핑 밴드의 다른 부위들과 유사한 유연성을 채널부에 부여하기 위한 것으로서, 실험적 또는 경험적으로 적절한 형상으로 형성하여 필요로 하는 착좌순응성을 충분히 확보할 수 있다. 물론, 착좌순응성이 크게 요구되지 않는 조건에서는 이미 개시된 종래기술과 같이 단순한 절개부로 대체할 수도 있다.On the other hand, the slot 15 that separates the central portion 17 and the two outer portion 19 of the channel portion is locally strengthened by the shape of the second step portion 23, the rigidity of the channel portion 3 is strengthened object In order to impart a similar flexibility to other portions of the clamping band in order to prevent poor seating compliance to the channel portion, it can be formed in an appropriate shape experimentally or empirically enough to secure the necessary seating compliance. Of course, in a condition where seating compliance is not greatly required, it may be replaced by a simple incision like the prior art already disclosed.

상기 연장부(5)는 상기 제2계단부(23)의 경사 각도에 상응하는 경사절단부 (25)를 구비하고 있는데, 이는 상기와 같은 경사를 가진 제2계단부(23)에 대하여 연장부(5)가 상응하는 형상을 가지도록 함으로써, 클램핑 밴드의 전체 길이를 단축하여 재료비의 절감이 가능하도록 함과 동시에 내측밴드부(9)와 외측밴드부(7)의 중심선 일치가 더욱 완전하게 이루어지도록 하는 것이다.The extension part 5 has an inclination cut part 25 corresponding to the inclination angle of the second step part 23, which is an extension part with respect to the second step part 23 having the inclination as described above. By having a corresponding shape 5), the overall length of the clamping band can be shortened to reduce the material cost, and at the same time, the center line matching between the inner band portion 9 and the outer band portion 7 is more complete. .

즉, 연장부(5)가 내측밴드부(9)에 연결된 구조가 종래와 같이 직각으로 절개된 구조이면 상기와 같이 경사진 제2계단부(23)에 밀착된 상태로 결합이 이루어질 수 없으므로, 도시된 바와 같이 제2계단부(23)의 경사에 상응하는 경사로 절단된 경사절단부(25)를 구비함으로써, 클램핑 밴드의 완전체결 상태에서 상기 경사절단부(25)가 제2계단부(23)에 완전히 밀착될 수 있도록 하고, 상기와 같이 경사절단부(25)가 제2계단부(23)에 완전히 밀착되면 자동적으로 내측밴드부(9)와 외측밴드부(7)의 중심선이 일치되는 상태는 더욱 확고해지게 되어, 결국 상기와 같은 내측밴드부(9)와 외측밴드부(7)의 중심이 일치하도록 가이드하는 데에 필요한 힘을 제공하는 데에 소요되는 채널부 및 연장부의 길이를 종래에 비해 축소되도록 할 수 있는 것이다.That is, when the structure in which the extension part 5 is connected to the inner band part 9 is a structure cut at right angles as in the prior art, the coupling cannot be made in close contact with the inclined second step part 23 as described above. By having the inclined cut portion 25 cut to the inclination corresponding to the inclination of the second step portion 23 as described above, the inclined cut portion 25 is completely connected to the second step portion 23 in the state of fully clamped band. When the inclined cutting portion 25 is completely in contact with the second step portion 23 as described above, the state in which the center lines of the inner band portion 9 and the outer band portion 7 coincide automatically becomes more firm. As a result, the length of the channel portion and the extension portion required to provide the force necessary to guide the center of the inner band portion 9 and the outer band portion 7 as described above can be reduced compared to the conventional. will be.

상기 후크부(11)에 구비되는 후크(27)는 구멍부(29)와, 밴드(13)의 표면으로부터 돌출되도록 상기 구멍부(29)에 연이어 형성되는 돌출절곡부(31)와, 상기 돌출절곡부(31)로부터 클램핑 밴드의 길이방향으로 돌출되어 상기 구멍부(29)의 내측으로 돌출되는 돌출걸림부(33)와, 상호 결합될 대응 형상을 가진 후크의 돌출걸림부가 끼워지도록 상기 돌출절곡부 및 돌출걸림부에 형성된 함몰결합부(35)로 구성되고, 상기와 같은 형상의 단위 후크(27)는 내측밴드부(9)와 외측밴드부(7)에 각각 상응하게 1개 이상씩 서로 결합될 수 있는 방향으로 설치된다.The hook 27 provided in the hook portion 11 includes a hole portion 29, a protruding bent portion 31 formed in succession to the hole portion 29 so as to protrude from the surface of the band 13, and the protrusion. The protrusion bent so that the protrusion catching portion 33 protruding in the longitudinal direction of the clamping band from the bent portion 31 and protruding inwardly of the hole portion 29 and the protrusion catching portion of the hook having a corresponding shape to be coupled to each other are fitted. Consists of a recessed coupling portion 35 formed in the portion and the projection engaging portion, the unit hook 27 of the above shape is to be coupled to each other at least one corresponding to the inner band portion 9 and the outer band portion (7), respectively. Can be installed in the direction that can be.

참고적으로, 도시된 본 실시예에서는 각각 내측밴드부(9)와 외측밴드부(7)에 2개씩 서로 결합될 수 있도록 설치되어 있다.For reference, in the illustrated embodiment, the inner band part 9 and the outer band part 7 are provided so as to be coupled to each other.

여기서, 상기 함몰결합부(35)는 상기 돌출절곡부(31) 및 돌출걸림부(33)를 밴드(13)의 표면으로부터 돌출되도록 가압하면서 자연적으로 형성되는 함몰부를 이용하여 형성하는 것이 바람직하며, 상기 돌출절곡부(31) 및 돌출걸림부(33)가 밴드(13)의 표면으로부터 돌출되는 높이는 밴드(13)의 두께만큼 또는 그 두께를 크게 초과하지 않을 만큼만 돌출되도록 형성하는 것이 바람직하다.Here, the depression coupling portion 35 is preferably formed using a depression that is naturally formed while pressing the protrusion bending portion 31 and the protrusion catching portion 33 to protrude from the surface of the band 13, It is preferable that the protrusion bent portion 31 and the protrusion catching portion 33 protrude from the surface of the band 13 so as to protrude only as much as the thickness of the band 13 or not greatly exceeding the thickness thereof.

상기와 같이 이루어진 후크(27)는 상응하는 후크와 결합되면서 상응하는 두 돌출절곡부(31)가 서로 반대편의 함몰결합부(35)에 끼워지게 되는데, 여기서 상기 돌출절곡부(31)와 함몰결합부(35)의 결합상태는 그 결합방향의 반대방향을 제외한나머지 5 방향에 대하여 상호간의 움직임을 구속하는 상태이므로, 결국, 내측밴드부(9)와 외측밴드부(7)가 결합되어 클램핑 밴드의 직경이 확대되는 방향으로의 상대 운동을 구속 하는 종래의 서포트후크의 역할은 물론, 내측밴드부(9)와 외측밴드부(7)의 중심이 일치된 상태로 유지되도록 하는 힘과 외측밴드부(7)의 자유단이 내측밴드부(9)의 외측으로 벌어지려고 하는 것을 억제하도록 하는 힘을 동시에 제공하게 되어 종래기술에서 개시된 서스펜션후크의 역할을 아울러 수행할 수 있다.Hook 27 made as described above is coupled to the corresponding hook and the corresponding two protruding bent portion 31 is fitted to the recess coupling portion 35 of the opposite side, where the protruding bent portion 31 and the depressed coupling Since the engaged state of the part 35 restrains mutual movements in the remaining five directions except for the opposite direction of the engaging direction, the inner band part 9 and the outer band part 7 are combined to form a diameter of the clamping band. The role of the conventional support hook to restrain the relative movement in the enlarged direction, as well as the force and the freedom of the outer band portion 7 so that the centers of the inner band portion 9 and the outer band portion 7 are kept in the same state. At the same time, it is possible to provide a force for suppressing that the stage is to be opened to the outside of the inner band portion (9) can also perform the role of the suspension hook disclosed in the prior art.

또한, 상기 후크(27)는 이어부(1)에 근접하여 형성하도록 하여 이어부(1)로부터 외측밴드부(7)의 자유단까지의 길이가 짧게 형성될 수 있도록 할 수 있는데, 이는 상기한 바와 같이 후크(27)의 돌출절곡부(31) 및 돌출걸림부(33) 높이가 밴드(13)의 두께만큼 또는 그 두께를 크게 초과하지 않을 만큼만 돌출되게 형성되면 충분하므로, 후크(27)의 결합 상태에서 밴드(13)의 표면으로 돌출되는 부분이 거의 없어 이어부(1)를 소성 변형시키기 위해 사용되는 집게와의 간섭문제를 염려할 필요가 없기 때문이다.In addition, the hook 27 may be formed in close proximity to the ear portion 1 so that the length from the ear portion 1 to the free end of the outer band portion 7 may be shortened. As such, it is sufficient that the protruding bent portion 31 and the protruding hook portion 33 height of the hook 27 are formed to protrude only as much as the thickness of the band 13 or not to greatly exceed the thickness thereof. This is because there is almost no portion protruding to the surface of the band 13 in the state, so there is no need to worry about the interference problem with the forceps used to plastically deform the ear portion 1.

결국, 1쌍 이상의 후크(27)만 있으면 클램핑 밴드의 가체결 상태를 충분히 구속하도록 할 수 있어서, 소요되는 밴드(13)의 길이를 축소하여 재료비를 절감할 수 있는 것이다.As a result, if only one or more pairs of hooks 27 are provided, it is possible to sufficiently restrain the pre-tightening state of the clamping band, thereby reducing the cost of the material by reducing the length of the band 13 required.

이상 설명한 바와 같이 본 발명에 의한 클램핑 밴드는 간단한 취급으로 원하는 체결력을 손쉽게 얻을 수 있도록 하면서도 제작하는 데에 소요되는 재료의 길이를 크게 축소하여 제조원가를 효과적으로 절감할 수 있도록 한다.As described above, the clamping band according to the present invention makes it possible to easily obtain a desired fastening force with simple handling, while significantly reducing the length of the material required to manufacture, thereby effectively reducing the manufacturing cost.
