Description

당김에 의하여 수동작동되는 셔터의 구동모터 {The motor of shutter hand operated out of bell pull}Drive motor of shutter operated manually by pulling {The motor of shutter hand operated out of bell pull}

본 발명은 셔터의 구동모터에 관한 것으로, 셔터의 승하강을 안내하는 모터의 구동이 전원이 OFF된 상태(정전,화재,폐점일 경우)에서 수동조작으로 셔터를 구동토록 한 것으로, 특히 수동조작을 위한 당김줄에 의하여 수동으로 자동변환되면서 구동이 가능토록 한 것이다.The present invention relates to a driving motor of the shutter, wherein the driving of the motor for guiding the rising and falling of the shutter is to drive the shutter by manual operation in a power-off state (when power failure, fire or closing), in particular manual operation. It is possible to drive while automatically converting manually by the pull line for.

현재 셔터의 승하강을 유도하는 구동모터는 전원에 의하여 구동모터가 정회전 또는 역회전하면서 승하강하게 되는데 특히 화재발생시에 자동으로 셔터가 하강한 상태에서 전원이 OFF될 경우에 실내에 남아 있는 사람이 셔터를 들어올려 탈출하지 못하게 되는 사례가 빈번하게 발생된다라는 것이다.The driving motor that induces the ascending and descending of the shutter is moved up and down while the driving motor is rotated forward or reverse by the power supply. Especially, when a power is turned off while the shutter is automatically lowered when a fire occurs, There is a frequent occurrence of lifting the shutter and failing to escape.

또한 화재뿐만이 아니라 상점등의 폐점에 따라 셔터를 내린상태에서 전원을 OFF하게 될 경우에 실내에 남아 있는 사람들이 빠져나갈 수 없게 되는 문제점이 있게 되는 것이다.In addition, there is a problem that people remaining in the room can not escape when the power is turned off while the shutter is lowered according to the closing of shops and the like as well as the fire.

따라서 이러한 문제점의 해결을 위하여 구동모터에 전원이 OFF되었을 경우에 보조밧데리를 사용하여 구동이 가능토록 하고 있으나 이러한 전원밧데리의 충전량의 감소에 따라 일정시간이 경과되면 작동이 되지 않게 되는 문제점이 존재하게 되는 것이다.Therefore, in order to solve this problem, when the power supply to the drive motor is turned off, it is possible to use the auxiliary battery to operate. Will be.

따라서 수동조작에 의하여 구동모터를 수동으로 구동이 가능토록 하는 방식이 제안되고 있으나 이러한 것들의 대부분은 전환스위치를 조작함으로서 수동조작에 의한 구동이 가능하게 됨으로 이러한 전환스위치의 조작이 불편하여 실질적인 사용에 어려움이 존재하게 된다라는 것이다.Therefore, a method of manually driving the driving motor by manual operation has been proposed. However, most of these operations can be driven by manual operation by operating a changeover switch, which makes the operation of the changeover switch inconvenient and practical. Difficulties will exist.

따라서 본 발명은 수동조작을 위한 코일체인(PROOF COIL CHAIN)(로드체인 또는 링크체인 또는 공업용체인 또는 쇠사슬이라고도 함)을 사용하여 당김에 의하여 자동적으로 구동모터가 구동토록 함으로서 간단한 조작에 의한 셔터의 들어올림이 가능토록 한 것이다.Therefore, the present invention is to provide a driving motor is driven automatically by pulling using a PROOF COIL CHAIN (also known as a load chain or link chain or industrial chain or chain) for manual operation, so that the shutter can be lifted by a simple operation. It is possible to raise.

이를 위하여 통상의 구동모터의 구동축을 구동모터에서 약간 돌출되게 형성한 후 상기 돌출된 구동축에 걸림축을 양측으로 돌출되게 형성한 후 구동모터의 구동축이 돌출된 측으로 스프링에 의하여 탄력지지되는 구동휠을 위치토록 하고, 상기 구동휠은 스프링에 의하여 구동모터와 이격된 상태에서 위치되어 있다가 수동조작이 이루어질 경우에 구동휠에 감겨진 코일체인을 당김토록 하면 구동휠이 1차로 회전되면서 스프링을 가압하여 구동모터의 구동축에 양측으로 돌출되게 형성된 걸림축에 걸림되어지도록 한 후 코일체인을 계속 당김토록 하면 2차로 구동모터의 구동축이 구동토록 한 것이다.To this end, the drive shaft of the conventional drive motor is formed to protrude slightly from the drive motor, and then the locking shaft is formed to protrude from both sides of the protruded drive shaft, and then the drive wheel is elastically supported by the spring toward the protruded side of the drive motor. When the driving wheel is positioned in a state spaced apart from the driving motor by a spring and pulls the coil chain wound around the driving wheel in the case of manual operation, the driving wheel is rotated first and the spring is driven by pressing the spring. If the driving shaft of the motor is engaged with the locking shaft formed to protrude on both sides, and the coil chain is pulled continuously, the driving shaft of the driving motor is driven secondarily.

따라서 전원이 OFF된 상태(정전,화재,폐점)일 경우 코일체인의 당김조작만으로 구동모터를 수동으로 조작이 가능함은 물론 평상시에는 전원에 의하여 구동이 가능토록 됨으로서 간단한 구조이면서도 간단하게 조작이 가능하게 되는 것이다.Therefore, when the power is off (power outage, fire, closing), the drive motor can be operated manually only by pulling the coil chain, and it can be driven by the power supply at all times. Will be.

도1 내지 도6에 도시된 바와 같이 본 발명의 구성은 구동모터(30)에 일정거리 이격되어지게 지지되어지는 커버판(50)과 상기 커버판(50)의 내측면에 장착고정되는 회전축(52)과 상기 회전축(52)에 끼워져 회전되어지는 캠(53)과 상기 캠(53)의 외측에서 방사상으로 위치되어져 캠(53)의 회전을 단속하게 되는 조임볼트(56)가 내장되어지는 가이드관(55)과 상기 캠(53)은 상사점과 하사점을 갖고 상기 상사점에는 걸림돌기(54)가 돌출형성되고, 상기 캠(53)의 상사점과 하사점에 슬라이드되면서 이동되는 슬라이드축(11)을 일측면에 돌출되게 형성되는 구동휠(10)과 상기 구동휠(10)의 타측면에는 구동휠이 구동모터(30)와 일정거리 이격되어지게 탄력지지되어지는 스프링(40)이 내입되어지는 안착홈(12)과 상기 안착홈(12)에 안착되어진 스프링(40)의 탄성작동시 간섭이 발생되지 않는 위치에 돌출되어지는 걸림돌축(16)과 상기 걸림돌축(16)의 내측으로 형성되는 축홀(13)을 형성하는 돌출벽(15)과 상기 돌축벽(15)에 의하여 형성되는 축홀(13)에 내입되어지는 관링(14)으로 이루어지는 구동휠(10)과 상기 구동휠(10)의 걸림돌축(16)과 맞물리도록 돌출되어지는 구동모터(30)의 구동축(31)에 장착되는 걸림부(32)로 이루어지는 구성이다.As shown in FIGS. 1 to 6, the configuration of the present invention includes a cover plate 50 that is supported to be spaced apart from the driving motor 30 by a predetermined distance, and a rotation shaft that is fixed to an inner surface of the cover plate 50. 52 and a guide 53 in which the cam 53 inserted into the rotation shaft 52 and the tightening bolt 56 radially positioned outside the cam 53 to interrupt the rotation of the cam 53 are embedded. The tube 55 and the cam 53 have a top dead center and a bottom dead center, and a locking protrusion 54 protrudes at the top dead center, and the slide shaft is moved while being slid to the top dead center and the bottom dead center of the cam 53. On the other side of the driving wheel 10 and the driving wheel 10 which is formed to protrude 11 on one side and the spring 40 is elastically supported so that the driving wheel is spaced apart from the driving motor 30 by a predetermined distance. Interference occurs during elastic operation of the seating groove 12 to be inserted and the spring 40 seated in the seating groove 12. A shaft wall 13 formed by the projection wall 15 and the shaft wall 13 forming the locking projection shaft 16 protruding at a position not to be formed and the shaft hole 13 formed inward of the locking projection shaft 16. A locking portion mounted to the driving wheel 10 of the driving ring 10 formed of the pipe ring 14 and the driving shaft 31 of the driving motor 30 protruding to engage with the locking protrusion 16 of the driving wheel 10. It consists of 32.

이때 구동휠(10)에는 코일체인(20)이 걸쳐져 코일체인의 당김시에 구동휠(10)이 회전토록 되는 것이고, 이러한 코일체인(20)의 당김에 의하여 구동모터(30)와 스프링(40)에 의하여 탄력지지되어 구동모터(30)와 이격되어져 있는 상태에 있는 구동휠(10)이 1차로 구동모터(30)의 구동축(31)측으로 이동하면서 구동휠(10)의 걸림돌축(16)이 구동축(31)의 걸림부(32)와 걸림되어지고, 이와 같이 1차로 연결된 상태에서 구동휠(10)이 계속 회전하게 되면 스프링(40)이 가압된 상태에서 회전되어져 구동모터(30)의 구동축(31)을 수동으로 회전토록 한 것이다.At this time, the driving wheel 10 is rotated to the driving wheel 10 so that the driving wheel 10 rotates when the coil chain is pulled, and the driving motor 30 and the spring 40 are pulled by the coil chain 20. The driving wheel 10 in the state of being elastically supported by the drive motor 30 and spaced apart from the driving motor 30 is primarily moved toward the driving shaft 31 of the driving motor 30, and thus, the locking protrusion 16 of the driving wheel 10 is moved. When the driving wheel 10 continues to rotate while being engaged with the locking portion 32 of the drive shaft 31, the spring 40 is rotated in a pressurized state so that the driving motor 30 may be rotated. The drive shaft 31 is rotated manually.

즉 구동휠(10)은 구동모터(30)와 스프링(40)의 복원력에 의하여 평상시에는 연결되지 않토록 이격되어진 상태가 유지되도록 하면서 수동조작의 필요성이 있을 경우에 코일체인(20)을 당김토록 하면 구동휠(10)이 1차로 회전되어지면 스프링(40)이 가압되면서 구동모터(30)의 구동축(31)과 구동휠(10)이 걸림돌축(16)과 걸림부(32)가 서로 맞물림되어져 연결되어지도록 하고, 그 상태에서 구동휠(10)이 계속회전이 이루어지면 구동축(31)이 구동되면서 셔터가 들어올려지도록 되는 것이다.That is, the driving wheel 10 is pulled by the coil chain 20 when there is a necessity of manual operation while maintaining the spaced state so as not to be normally connected by the restoring force of the driving motor 30 and the spring 40. When the driving wheel 10 is primarily rotated, the spring 40 is pressurized while the driving shaft 31 and the driving wheel 10 of the driving motor 30 are engaged with the engaging shaft 16 and the engaging portion 32. When the drive wheel 10 is continuously rotated in that state, the drive shaft 31 is driven while the shutter is lifted.

이때 구동휠(10)의 회전이 중지될 경우에 즉 코일체인(20)의 당김을 정지할 경우에는 자동적으로 구동휠(10)이 구동모터(30)의 구동축(31)과 분리되어지도록 되면서 들어올려지는 셔터가 정지하게 되는 것이다.In this case, when the rotation of the driving wheel 10 is stopped, that is, when the pulling of the coil chain 20 is stopped, the driving wheel 10 is automatically separated from the driving shaft 31 of the driving motor 30. The raised shutter will stop.

이때 구동모터에는 정지수단이 형성되어 있어서, 들어올려진 상태가 정지되는 것이고, 이러한 정지수단은 구동모터(30)에서 이미 사용되어지는 공지의 기술이기 때문에 상세한 설명은 생략토록 하고, 일한 정지수단이 본 발명의 목적을 제한하는 것이 아니다.At this time, the stopper is formed in the drive motor, and the lifted state is stopped. Since the stopper is a known technique that is already used in the drive motor 30, the detailed description thereof will be omitted. It is not intended to limit the purpose of the invention.

이는 상기 구동휠(10)은 구동모터(30)와 스프링(40)에 의하여 일정거리 이격되어진 상태가 유지되어지다가 코일체인(20)을 당김토록 하면 스프링(40)을 1차 가압하고 그 후 가압된 상태에서 회전토록 하고 회전이 정지되면 가압되어 있는 스프링(40)의 복원력에 의하여 구동모터(30)의 구동축(31)과 구동휠(10)의 연결상태가 자동적으로 해제되는 것이다.This is because the driving wheel 10 is maintained in a state where a certain distance is separated by the driving motor 30 and the spring 40, and when the coil chain 20 is pulled, the spring 40 is first pressurized and then pressurized. When the rotation is stopped and the rotation is stopped, the connection state of the drive shaft 31 and the drive wheel 10 of the drive motor 30 is automatically released by the restoring force of the spring 40 being pressed.

이러한 스프링(40)의 가압과 해제의 장력조절은 구동휠(10)이 지지볼트(51)에 의하여 구동모터(30)와 일정거리 이격된 상태로 고정되어지는 커버판(50)의 내측에 위치되어지고, 커버판(50)의 내측면으로는 구동휠(10)의 정회전을 유도하는 회전축(52)과 회전축(52)을 감싸면서 구동휠(10)이 스프링(40)을 가압하면서 가압된 상태에서 회전되고 회전이 정지되면 구동모터(30)의 구동축(31)과의 연결이 자동으로 끊어지도록 하기 위하여 상사점과 하사점이 만곡되게 형성되는 캠(53)이 장착되고, 상기 캠(53)의 상사점에는 걸림돌기(54)가 형성되어 구동휠(10)이 코일체인(20)의 당김시 회전되면서 스프링(40)을 가압하기 위하여 가이드축(11)이 하사점에서 상사점으로 이동하면서 스프링(40)을 가압하여 구동모터(30)의 구동축(31)과 연결된 상태의 고정이 이루어지고, 그 상태의 유지를 위하여 캠(53)이 커버판(50)에서 회전축(52)에서 회전토록 하고, 상기 캠(53)은 일정한 저항성을 유지하기 위하여 캠(50)의 외측에서는 가이드관(55)이 형성되어 저항의 조절을 위한 조임볼트가 내입되어지는 것이다.The tension adjustment of the pressurization and release of the spring 40 is located inside the cover plate 50 in which the driving wheel 10 is fixed at a predetermined distance from the driving motor 30 by the support bolt 51. On the inner surface of the cover plate 50, the driving wheel 10 pressurizes the spring 40 while pressing the spring 40 while surrounding the rotating shaft 52 and the rotating shaft 52 which guide the forward rotation of the driving wheel 10. In the rotated state and the rotation is stopped, the cam 53 is formed to be curved to the top dead center and the bottom dead center so that the connection to the drive shaft 31 of the drive motor 30 is automatically disconnected, the cam 53 At the top dead center of the top surface, a locking protrusion 54 is formed, and the guide shaft 11 moves from the bottom dead center to the top dead center to pressurize the spring 40 while the driving wheel 10 rotates when the coil chain 20 is pulled. While pressing the spring 40 is fixed in a state connected to the drive shaft 31 of the drive motor 30, the state To maintain the cam 53 is rotated on the rotation shaft 52 in the cover plate 50, the cam 53 is formed with a guide tube 55 on the outside of the cam 50 to maintain a constant resistance Tightening bolts are inserted to adjust the resistance.

이때 상기 구동휠(10)의 일측면으로 돌출된 가이드축(11)은 둥그랗게 형성되면서도 선단이 뾰족한 형상을 유지토록 함으로서 캠(53)과의 마찰저항을 최소로 하면서도 용이한 작동이 가능토록 한 것이다.At this time, the guide shaft 11 protruding to one side of the driving wheel 10 is formed to be round and maintains a sharp shape at the tip, thereby minimizing frictional resistance with the cam 53 and enabling easy operation. will be.

따라서 구동휠(10)의 외경은 커버판(50)의 외경보다 작은 것이고, 커버판(50)이 지지볼트에 의하여 구동모터(30)와 지지되면서 고정될 경우에 지지볼트는 구동휠(10)을 간섭하기 않게 되는 것이다.Therefore, the outer diameter of the drive wheel 10 is smaller than the outer diameter of the cover plate 50, the support bolt is the drive wheel 10 when the cover plate 50 is fixed while being supported with the drive motor 30 by the support bolt (10) Will not interfere.

따라서 평상시에는 스프링(40)에 의하여 구동휠(10)이 구동모터(30)와 연결되어 있기 않기 때문에 전원에 의하여 구동축(31)이 평상시 대로 구동되어지다가 전원이 OFF될 경우에 구동휠(10)에 권취되어진 코일체인(20)을 당김토록 하면 1차로 구동휠(10)이 회전되어지면서 구동휠(10)이 캠(53)의 하사점에서 상사점으로 이동되면서 스프링(40)을 가압하여 구동모터(30)의 구동축(31)과 밀착되어지면서 구동축(31)의 양측에 돌출되게 형성된 걸림부(32)와 구동휠(10)의 걸림돌기(54)가 걸림되어진 상태에서 계속 회전토록 하면 그 상태가 유지된 상태에서 구동휠(10)이 회전하게 되면 구동휠(10)은 커버판(50)의 캠(53)의 상사점에서 위치된 상태에서 회전이 이루어지게 되고, 그러면 구동휠(10)의 걸림돌기(54)에 의하여 맞물려 있는 구동축(31)이 회전되면서 셔터를 들어올리게 되는 것이다.Therefore, since the driving wheel 10 is not normally connected to the driving motor 30 by the spring 40, the driving wheel 31 is driven as usual by the power supply, and the driving wheel 10 is turned off when the power is turned off. When pulling the coil chain 20 wound on the driving wheel 10 is primarily rotated while the driving wheel 10 is moved from the bottom dead center of the cam 53 to the top dead center driving by pressing the spring (40). When the locking portion 32 and the locking protrusion 54 of the driving wheel 10 are formed to protrude on both sides of the driving shaft 31 while being in close contact with the driving shaft 31 of the motor 30, the rotating portion is continuously rotated in the locked state. When the driving wheel 10 rotates while the state is maintained, the driving wheel 10 is rotated in a state where it is located at the top dead center of the cam 53 of the cover plate 50, and then the driving wheel 10 Drive shaft 31, which is engaged by the engaging projection 54, is rotated to lift the shutter. .

그후 들어올림이 중지될 경우에는 당김를 위한 코일체인(20)을 놓게 되면 구동휠(10)은 가압되어져 있는 스프링(40)의 복원력에 의하여 자동적으로 캠(53)의 하사점으로 이동되면서 복귀하게 되어 구동모터(30)의 구동축(31)과 연결이 끊어지게 되는 것이다.Then, when lifting is stopped, when the coil chain 20 for pulling is released, the driving wheel 10 is automatically moved to the bottom dead center of the cam 53 by the restoring force of the spring 40 which is pressurized. The connection with the drive shaft 31 of the drive motor 30 is to be broken.

따라서 전원이 OFF된 상태 즉, 정전이나 화재 발생시나 폐점시에 셔터를 수동으로 작동할 경우 코일체인(20)의 작동으로 구동모터(30)를 수동으로 작동시킬 수 있게 되는 것이다.Therefore, when the power is turned off, that is, when the shutter is manually operated in the event of power failure or fire or closing, the driving motor 30 can be manually operated by the operation of the coil chain 20.
