These blind curtains are vertical blinds, horizontal blinds, or overlapped blinds, rolled blinds, etc. The form also appears in various ways.
중첩형 블라인드는 여러 장의 블라인드 날개를 하나의 줄로 연결하여 회전축과 연동하는 작동부를 감거나 풀어서 개개의 블라인드 날개가 일률적으로 상승 또는 하강시키도록 하는 구성을 가지며, 블라인드 날개를 뉘이거나 세우는 등의 각도를 조절하여 조도 조절도 가능하도록 한다.Nested blinds have a configuration that allows individual blind wings to be raised or lowered uniformly by winding or unwinding the moving parts linked with the rotating shaft by connecting several blind blades in a single row. Adjust the illuminance.
그러나 이와 같은 구성은 개개의 블라인드 날개가 무리하게 일률적으로 움직이면서 꼬이거나 엉키고, 그러한 상황에 접할 시 블라인드 전체를 해체하여 교체 및 수리를 해야하는 폐단이 있다.However, this configuration has the disadvantage that individual blind wings are twisted or entangled by excessively uniform movement, and when the situation is encountered, the entire blind must be dismantled and replaced and repaired.
그에 반해, 하나의 스크린이 권취관에 감겨 작동부의 조절에 의해 감기거나 펼쳐지는 롤 형태의 블라인드는 중첩식 블라인드에 비해 취급 및 관리가 용이하며 스크린 인쇄 등을 통해 미려한 실내분위기 연출도 이루어질 수 있어 각광받고 있다.On the other hand, roll-shaped blinds, in which a single screen is wound around the winding tube and wound or unfolded by adjustment of the operating part, are easier to handle and manage than overlapped blinds, and the screen atmosphere can be used to produce a beautiful indoor atmosphere. I am getting it.
상기의 롤 형태의 블라인드의 통상적인 구성을 상세히 살펴보면, 외주 면에는 스크린이 감겨 있고 끝단에는 손잡이가 형성된 권취관이 개구부의 상측에 설치되고, 권취관의 내부에는 클러치와 회전축을 포함하여 상기 회전축과 연동하는 작동 줄이 권취관의 일단에 설치되어 있는 구성을 갖는다.Looking at the conventional configuration of the roll-shaped blinds in detail, the outer circumferential surface is wound around the screen and the end of the winding pipe formed with a handle is installed on the upper side of the opening, the inside of the winding pipe including the clutch and the rotating shaft and the rotating shaft and The interlocking working string has a configuration installed at one end of the winding pipe.
상기와 같은 구성을 갖는 롤 블라인드는 회전축에 감겨 두 줄로 나뉘어 하부로 떨어지는 상기 작동 줄의 선택적인 당김에 의해 스크린이 감겨 지거나 펼쳐지도록 되어 있다.The roll blind having the above configuration is configured to be wound or unrolled by the selective pulling of the operating line which is divided into two rows wound around the rotating shaft and falls downward.
이러한 롤 블라인드는 상부에 권취부를 가지어 스크린이 하향하며 펼쳐지는 형태로 이루어져 전체 개구부 면적에서 수요자가 필요로 하는 소정의 높이와 면적만을 열 수 없어 수요자의 요구에 부합하지 못하는 폐단이 있었으며, 또한, 통상 한 장의 얇은 원단으로 이루어지는 스크린은 채광조절이 유동적으로 이루어지지 못해 일사량이 많은 경우 일광이 투과되는 등의 문제점이 있었다.These roll blinds have a winding part on the upper side, and the screen is downwardly spread, and thus, the roll blinds cannot open only a predetermined height and area required by the consumer in the entire opening area. In general, a screen made of a single thin fabric has a problem that daylight control is not made because the light adjustment is not made in a fluid manner.
상기와 같은 롤 블라인드 커튼의 문제점을 해결하고자 커튼지를 이중으로 구성한 이중 블라인드 커튼이 개발되어 사용되어 있다.In order to solve the problems of the roll blind curtain as described above, a double blind curtain having double curtains has been developed and used.
이러한 이중 블라인드 커튼은 커튼지를 이중으로 구성해 소비자의 욕구를 보다 충족시킬 수 있도록 노력한 것으로, 이중으로 형성된 커튼지로 인해 채광조절을 보다 유동적으로 수행할 수 있는 것은 물론 사용자의 욕구에 보다 충족할 수 있는 블라인드 커튼을 제공할 수 있었다.These double blind curtains are made to double the curtains to meet the needs of consumers, and due to the double-formed curtains can be more flexible to meet the needs of the user, as well as to perform the light control more flexibly Could provide blind curtains.
하지만, 상기한 이중 블라인드 커튼은 실용적인 면에서는 소비자의 욕구를 어느 정도 충족할 수 있지만 커튼의 또 다른 목적인 실내 인테리어 적인 면에서는 다양한 소비자의 욕구를 충족할 수 없는 문제점이 있는 것으로, 이는 일반적으로 블라인드 커튼은 하나의 패턴으로 이루어진 커튼지를 사용하기 때문에 블라인드 커튼 전체를 교체하지 않는 이상 항상 같은 커튼지를 볼 수밖에 없는 문제점이 있어 실내 인테리어에 변화를 주고자 할 때 상당한 문제점이 발생하는 등 소비자가 필요로 하는 다양한 효과를 얻고자 하는 데는 상당한 문제점이 있었다.However, the above-mentioned double blind curtain can satisfy the needs of consumers to some extent in practical terms, but there is a problem in that the interior of the curtain, which is another purpose of the curtain, cannot satisfy the needs of various consumers, which is generally blind curtain. Has a problem that you have to see the same curtains all the time unless you replace the entire blind curtain. There was a significant problem with trying to be effective.
상기와 같은 소비자의 다양한 인테리어 욕구를 만족시키기 위해 본 발명자는 2장 이상의 커튼지를 높이방향으로 연결하여 제작한 커튼모델을 2개의 회전축을 가진 듀얼 롤에 설치하여 그 문제점을 해결한 바 있다. 그래서 이 장치는 두 개의 권취롤이 연결되어 다수의 다양한 커튼지가 작동하는 장치에 있어 각 축에 권취된 커튼량의 차이로 인해 어느 하나의 축으로부터 커튼 풀림량과 다른 하나의 축에 감김량을 동일하게 하는 수단을 구비하여야 하는 것이 필수 조건이 되게 되었다. 이와 관련하여 커튼이 감겨진 축의 외경 회전량이 동일하게 작동하게 될 때, 다른 한편으로 축 중심에 작용하는 회전비는 항상 동일하지 않는 특수성이 발생 된다. 이러한 특수성은 어느 한쪽 축의 회전비율이 항상 높거나 낮은 경우가 아니라 높은 경우와 낮은 경우가 혼재하고 있는 특수한 것이므로 어느 경우에도 동력전달이 원활하게 이루어질 수 있도록 하는 것은 난해한 과제이다. 이러한 현상은 본 발명자가 고안한 테잎벨트식 동력전달 장치가 구비된 이중블라인더 커튼에는 문제가 없으나 축의 회전비가 고정된 기어식 동력연결 장치를 적용하기 위해서는 새로운 고안이 필요하게 되었다.In order to satisfy the various interior needs of the consumers as described above, the present inventors have solved the problem by installing a curtain model produced by connecting two or more curtains in a height direction on a dual roll having two rotation shafts. Therefore, in this device, two winding rolls are connected to each other to operate a variety of curtains, and the amount of curtain unwinding from one axis and the amount of winding on one axis are the same due to the difference in the amount of curtain wound on each axis. It has become necessary to have a means to make them. In this connection, when the outer diameter rotation of the shaft on which the curtain is wound is operated equally, on the other hand, a specificity arises in which the rotation ratio acting on the shaft center is not always the same. This particularity is not a case where the rotation rate of one axis is always high or low, but a special case where a high case and a low case are mixed. Therefore, it is a difficult task to ensure smooth power transmission in any case. This phenomenon is not a problem in the double blind curtain curtain provided with a tape belt power transmission device devised by the present invention, but a new design is required to apply a gear type power connection device with a fixed rotation ratio of the shaft.
따라서 본 발명은 상기한 문제를 해소하기 위해 안출한 것으로서, 기존 기술의 기능적 한계를 획기적이고 효율적인 수단으로 혁신하여 실용성을 극대화한 것은 물론, 서로 연결된 2개의 축회전에 있어서 각 축이 필요로 하는 고유의 회전량에서 발생하는 차이에 상관없이 구동스프로켓의 회전방향에 따라 회전력이 2개의 축에 선택적으로 연결되어 작동하는 수단을 가진 이중블라인드커튼을 제공하는 데 그 목적이 있다.Therefore, the present invention has been devised to solve the above problems, innovating the functional limitations of the existing technology with innovative and efficient means to maximize practicality, as well as the inherent needs of each axis in the rotation of two axes connected to each other. It is an object of the present invention to provide a double blind curtain having a means for actuating and connecting the rotational force selectively to two axes according to the rotational direction of the drive sprocket, regardless of the difference occurring in the rotational amount of.

The driving unit 210 rotates about the main shaft 211 together with the driving sprocket 213 rotated by the driving chain 212 which the user manually operates and passes through the through hole 213a of the driving sprocket 213. It consists of a drive gear 214 is rotated together by the outer ring clutch bar 227c is connected to the fastening protrusion 214a provided on one side of the body, the power transmitted to the drive gear 214 is a rotation selection unit The rotation selector 500 selectively transmits the rotational force to either the first pulley gear 510a or the second pulley gear 510b according to the rotational direction of the driving sprocket 213. In this case, the driven pulley 241 that rotates as the first pulley gear 510a and the driven pulley 251 that rotates as the second pulley gear 510b are doubled by the tape belt 270 and the belt 260. Will be connected. First, the tape belt 270 connection made of a material having strong tensile strength connects the main pulley 241 and the driven pulley 251 in the same way as the curtain structure. In addition, the main pulley 241 and the driven pulley 251 are connected to the outer peripheral surface of the tape belt 270 wound as described above with a circular belt 260. This configuration is the same as the trend of the curtain curtain winding tape belt 270 is laminated on the pulleys (241 251) in accordance with the rotation of the shaft on the inner surface of the belt 260, the curtain circumference amount and tape wound on the winding rod The circumferential rotation of the belt is the same. At this time, the belt 260 and the tape belt 270 is preferably to have a friction force, such as to scratch the contact surface.
그리고 주동축(211)의 끝단에는 도면(도4 참조)에서 보는 바와 같이 축클러치(230)를 설치하고 권취봉 일단을 주동축(211)과 공회전 연결하는 권취연결구(217a)을 구비하고 축클러치(230)에 형성된 축연결홀(230a)과 권취연결구(217a)에 형성된 권취연결홀(217b)를 연결하는 내륜클러치바(227a)를 구비하여 주동축(211)에 도착한 회전력을 권취봉에 연결한다.

다음으로 상기 회전선택부(500)의 작동에 대하여 우선 설명하도록 한다.Next, the operation of the rotation selector 500 will be described first.
도면(도5 참조)에서 보는 바와 같이 회전선택부(500)는 센터축(550)이 구획판(130)에 천공되어 있는 축공(150)에 회동되도록 설치되고 구동기어(214)의 동력은 상기 센터축(550)에 고정된 미끄럼돌기(551)와 함께 회동하는 센터기어(560)에 치합 연결되며 센터기어(560)의 회전력은 상기 미끄럼돌기(551) 양 끝단 위치에 공회전하도록 설치하되 마주보는 측면에 일방향연결구(521a,521b)가 구비된 제1,2아이들기어(520a,520b) 사이에 위치하는 센터볼트(540)에 전달되는데, 회전력의 전달경로는 볼트몸통(541) 중심에 형성된 미끄럼홀(542)에 끼워진 미끄럼돌기(551)의 회전력에 의하여 볼트몸통(541) 외주면에 구비된 볼트나사산(543)이 센터너트(530) 내측면에 구비된 너트홈(531)의 가이드를 따라 전.후진 회전함으로써 볼트몸통(541)이 미끄럼돌기(551) 좌우로 슬라이딩 되고 이때 볼트몸통(541) 양 측면에는 일방향연결구(521c,521d)가 구비되어 있어 제1,2아이들기어(520a,520b)에 구비된 어느 하나의 대응하는 일방향연결구(521a,521b)에 연결되게 된다. 상기 제1,2아이들기어(520a, 520b) 어느 하나와 센터볼트(540)가 서로 연결된 후에는 센터볼트(540)가 센터너트(530) 내측에서 같은 방향으로 더 움직일 수 없고 센터너트(530) 몸체는 구획판(130) 축공(150) 내에서 공회전하고 있으므로 센터축(550)에 공회전하는 제1,2아이들기어(520a, 520b)중 어느 하나와 연결된 센터볼트(540)의 회전력은 센터기어(560)의 어느 한 방향 회전이 반대방향으로 전환되기까지 지속한다. As shown in FIG. 5 (see FIG. 5), the rotation selector 500 is installed so that the center shaft 550 rotates in the shaft hole 150 drilled in the partition plate 130, and the power of the drive gear 214 is The gear is connected to the center gear 560 which rotates together with the sliding protrusion 551 fixed to the center shaft 550. The rotational force of the center gear 560 is installed to rotate at both ends of the sliding protrusion 551, but is facing each other. It is transmitted to the center bolt 540 positioned between the first and second idler gears 520a and 520b having one- way connectors 521a and 521b on the side, and a transmission path of rotational force is a sliding formed at the center of the bolt body 541. The bolt thread 543 provided on the outer circumferential surface of the bolt body 541 is moved along the guide of the nut groove 531 provided on the inner surface of the center nut 530 by the rotational force of the sliding protrusion 551 inserted into the hole 542. By rotating backward, the bolt body 541 slides to the left and right of the sliding protrusion 551 and at this time, The body 541 on both sides has to be connected to the one-way connector with one-way connector corresponding to the (521a, 521b) provided on (521c, 521d) there are provided first and second idle gear (520a, 520b). After one of the first and second idle gears 520a and 520b and the center bolt 540 are connected to each other, the center bolt 540 may not move further in the same direction inside the center nut 530 and the center nut 530 may be used. Since the body is idling in the shaft hole 150 of the partition plate 130, the rotational force of the center bolt 540 connected to any one of the first and second idle gears 520a and 520b idling to the center shaft 550 is the center gear. Rotation in either direction of 560 continues in the opposite direction.
상기의 연결경로를 통해서 2개의 회전축(211,221) 각각에 설치된 제1,2풀리기어(510a, 510b)는 각각에 치합된 제1,2아이들기어(520a, 520b)를 통하여 회전력을 전달 받게 된다.Through the connection paths, the first and second pulley gears 510a and 510b installed in the two rotation shafts 211 and 221 respectively receive the rotational force through the first and second idler gears 520a and 520b meshed to the respective rotation shafts 211 and 221b.
이상과 같은 구성은 권취봉에 권취된 여러 장의 연속된 커튼(410)이 어느 하나의 권취봉에서 다른 권취봉으로 이동할 때 동일한 길이로 풀림과 감김의 동작을 가능하게 한다.  The above configuration enables the operation of unwinding and winding to the same length when a plurality of continuous curtains 410 wound on the winding rods move from one winding rod to another winding rod.
한편, 커튼의 승하강 동작의 경우는 회전변속부(220)의 작동으로 이루어 지는데 도면(도6 참조)에서 보는 바와 같이 먼저 상기 축클러치(230)와 권취연결구(217a)을 연결하는 내륜클러치바(227a)를 한쪽으로 이동(C)시켜 주동축(211)으로부터 전달되는 회전력을 주동권취봉(217)으로 부터 분리하여야 한다. 현재 축의 연결상태는 커튼(410)이 하나의 권취봉에서 다른 권취봉으로 이동할 때 동일한 길이로 풀림과 감김의 동작이 이루어지도록 최적화된 상태이기 때문이다. 상기와 같이 내륜클러치바(227a)를 이동(B→B')하는 방법은 도면(도4 참조)에서 보는 바와 같이 푸시버튼어셈블리(280)의 버튼당김줄(286)의 조작에 의하여 내륜클러치바(227a)가 결합된 내륜플레이트(227)를 이동하여 가능하게 할 수 있는데 이러한 작동은 볼펜의 버튼을 움직임으로써 볼펜심이 움직이는 원리와 동일한 것이므로 상세한 설명을 생략하도록 한다. On the other hand, in the case of the lifting operation of the curtain is made by the operation of the rotary transmission 220, as shown in the drawing (see Fig. 6), first, the inner ring clutch bar connecting the shaft clutch 230 and the winding connector 217a (227a) must be moved to one side (C) to separate the rotational force transmitted from the main shaft (211) from the main winding rod (217). This is because the current shaft is in a state in which the curtain 410 is optimized to unwind and wind with the same length when the curtain 410 moves from one winding rod to another winding rod. As described above, the inner clutch clutch bar 227a is moved (B → B ') as shown in FIG. 4 (see FIG. 4). As shown in FIG. 4, the inner clutch clutch bar is operated by the button pull string 286 of the push button assembly 280. The inner ring plate 227 to which the 227a is coupled can be moved. This operation is the same as the principle of moving the ballpoint pen by moving a button of the ballpoint pen, so that detailed description thereof will be omitted.
상기와 같이 내륜클러치바(227a)의 이동과 동시에 내륜클러치바(227a) 일단에 구비된 걸림돌기(227b)는 외륜클러치바(227c)가 결합된 환형요홈(227d)에 삽입되어 있어 내륜클러치바(227a)가 움직인 거리만큼 외륜클러치바(227c)를 움직이게 하고 상기 움직임을 통하여 외륜클러치바(227c)는 구동기어(214)의 체결돌기(214a)와 구동스프로켓(213)을 연결하던 위치(A)에서 구동스프로켓(213)과 주동권취봉(217) 일단에 구비된 권취연결구(217a)을 연결하는 위치(A')로 이동하게 된다. 상기와 같이 외륜클러치바(227c)의 위치가 이동된 후에 구동스프로켓(213)은 하나의 권취봉(217)만을 구동하게 되므로 커튼(410)의 승하강이 가능하게 된다. 한편 상기 환형요홈(227d)은 걸림돌기(227b)가 삽입되어 내외륜클러치바(227a,227c)의 좌우 동시이동을 가능하게 하지만, 각각의 회전에 대해서는 간섭하지 않도록 되어 있다.As described above, at the same time as the inner clutch bar 227a moves, the locking protrusion 227b provided at one end of the inner clutch bar 227a is inserted into the annular recess 227d to which the outer wheel clutch bar 227c is coupled. The outer ring clutch bar 227c is moved by the distance 227a is moved, and the outer ring clutch bar 227c connects the fastening protrusion 214a of the drive gear 214 and the drive sprocket 213 through the movement ( In A), the driving sprocket 213 and the winding winding rod 217 are moved to a position A 'for connecting the winding connector 217a provided at one end. Since the driving sprocket 213 drives only one winding bar 217 after the position of the outer ring clutch bar 227c is moved as described above, the curtain 410 can be moved up and down. On the other hand, the annular groove 227d is inserted into the engaging projection 227b to enable the left and right simultaneous movement of the inner and outer wheel clutch bars (227a, 227c), but does not interfere with each rotation.
이상 본 발명에 구비된 각각 구성이 만드는 작동과정을 도식화하여 표현한 그림이 도7 이다. 도7은 각각의 구성이 연결되는 상태를 도식화하여 표현함으로써 회전구동력의 전달과정을 체계적으로 이해할 수 있도록 하였다.7 is a diagram illustrating the operation process of each configuration provided in the present invention. 7 is a schematic representation of the state in which each configuration is connected to enable a systematic understanding of the process of transmitting rotational driving force.
본 발명은 커튼용 롤블라인더에 적용될 수 있을 뿐만 아니라 2개의 축이 회전비가 일정하지 않고 변동되는 경우에도 치합에 의한 동력전달을 가능하게 하는 기술이다. The present invention can be applied not only to the roll blinder for curtains, but also to enable power transmission by engagement even when the two axes of the rotation ratio are not constant and fluctuate.
