본 발명은 전동셔터의 정전시 체인휠이 클러치 기능을 하고 체인 전달력이 감김 및 풀림시 일정한 수동 수직형 구동장치에 관한 것이다.The present invention relates to a manual vertical drive device in which the chain wheel functions as a clutch in the event of a power failure of the electric shutter and the chain transmission force is constant during winding and unwinding.

일반적으로 셔터는 도 1과 같이 도어의 프레임 상부에 셔터를 감거나 푸는 셔터드럼(4)과, 셔터드럼(4)에 동력을 전하도록 드럼축공(3)을 가지는 감속기(2), 감속기(2)에 구동 동력을 일단에서 제공하는 모터(1), 모터(1)의 다른 출력단에서 정전시 수동으로 동력을 전달하고, 정전이 아닌 평소에는 동력전달이 해제되는 수동구동수단(5), 수동구동수단(5)이 수동시 동력을 전달하는 레버(7), 모터(1)의 다른 출력단에 부가된 제1베벨기어(8)를 포함한다. 또한, 상기 제1베벨기어(8)와 수동모드시 기어 결합하는 제2베벨기어(8-2), 제2베벨기어(8-2)와 동축으로 결합되어 체인(6)으로 동력을 제2베벨기어(8-2)에 전달하는 체인휠(8-1), 제2베벨기어(8-2)에는 축 결합하고 체인휠(8-1)과 축 결합하는 기어축(8-3), 기어축(8-3)을 고정하는 수동하우징(8-4), 상기 레버(7)를 유착시키며 모터(1)에 고정된 레버브라켓(8-5)을 포함한다.In general, as shown in Figure 1, a shutter consists of a shutter drum (4) on the upper part of the door frame for winding or unwinding the shutter, a reducer (2) having a drum shaft hole (3) to transmit power to the shutter drum (4), and a reducer (2). ), a motor (1) that provides driving power at one end, a manual drive means (5) that manually transmits power in the event of a power outage from the other output end of the motor (1), and power transmission is released in normal times other than power outages, manual drive The means 5 includes a lever 7 that transmits power when manual, and a first bevel gear 8 added to the other output end of the motor 1. In addition, a second bevel gear (8-2), which is gear-coupled with the first bevel gear (8) in manual mode, is coaxially coupled with the second bevel gear (8-2) and transmits power to the second bevel gear (8) through the chain (6).

본원발명의 전동셔터의 정전시 수동 수직형 구동장치는 모터(1) 일 출력단에 설치한 감속기(2)의 드럼축공(3)에 셔터를 감거나 푸는 셔터드럼(4)을 결합하고, 다른 출력단에서 모터(1)축을 체인(6)으로 회전시켜 수동으로도 구동하는 셔터장치로,The manual vertical driving device in case of power failure of the electric shutter of the present invention combines the shutter drum (4) for winding or unwinding the shutter with the drum shaft hole (3) of the reducer (2) installed at one output end of the motor (1), and the other output end of the motor (1). It is a shutter device that is driven manually by rotating the motor (1) shaft with a chain (6),

수직으로 설치되는 모터의 다른 출력단 단부에 축결합한 원판형 가바나패드(10);A disc-shaped gavana pad (10) axially coupled to the other output end of the vertically installed motor;

상기 가바나패드(10)와 정전시 면접촉하여 수동으로 동력을 전달하고 외주에 체인홈(21)을 가지고 있고 통전시 솔레노이드(23) 당김 자기력에 의하여 가바나패드(10)와 면접촉이 분리되고, 정전시 자기력이 해제되어 내장된 스프링(24) 탄발력으로 위로 상승하여 가바나패드(10)와 면접촉하여 수동으로 동력을 전달하여 클러치 기능을 하는 체인휠(22)이 수용된 클러치하우징(20); 및Power is transmitted manually through surface contact with the Gavana pad (10) during a power outage, and has a chain groove (21) on the outer circumference. When energized, the Gavana pad (10) and the surface contact are separated by the magnetic force of the solenoid (23), A clutch housing (20) in which the magnetic force is released during a power outage and the chain wheel (22) that rises upward by the elastic force of the built-in spring (24) and makes surface contact with the gavana pad (10) to manually transmit power to serve as a clutch is accommodated; and

클러치하우징(20) 정면에 부가되어 체인(6)의 이동방향을 수평에서 수직으로 바꾸는 일조의 당김휠(31,32)을 가지는 당김휠부(30)를 포함하여 구성한다.It is added to the front of the clutch housing 20 and includes a pulling wheel portion 30 having a set of pulling wheels 31 and 32 that change the moving direction of the chain 6 from horizontal to vertical.

상기, 체인휠(22)의 수평방향 대응 클러치하우징(20) 정면에는 체인(6)이 수평방향으로 통과하는 체인공(25)을 형성한다.A chain hole 25 through which the chain 6 passes in the horizontal direction is formed on the front of the clutch housing 20 corresponding to the horizontal direction of the chain wheel 22.

상기, 당김휠부(30)에 설치되는 일조의 당김휠(31,32)은 클러치하우징(20) 정면 부위의 당김휠부(30)에 고정시킨 브라켓(33)의 축에 베어링을 개재하여 양 당김휠(31, 32)이 같은 체인홈 배열 각도 위치에 동기를 맞추어 회전 가능토록 축결합한다.Above, a set of pulling wheels (31, 32) installed on the pulling wheel portion (30) are connected to both pulling wheels through bearings on the axis of the bracket (33) fixed to the pulling wheel portion (30) at the front of the clutch housing (20). (31, 32) are axially coupled so that they can rotate in synchronization with the same chain groove arrangement angle position.

상기 클러치하우징(20) 정면으로 체인휠(22)에서 수평방향으로 체인(6)을 통과시키는 체인공(25) 하단 높이 부위의 클러치하우징(20) 내에는 체인휠(22)을 클러치 작용하도록 구동하는 솔레노이드(23)가 체인휠(22)과 동축으로 설치되며,The chain wheel 22 is driven to act as a clutch within the clutch housing 20 at the lower height of the chain ball 25, which passes the chain 6 horizontally through the chain wheel 22 in front of the clutch housing 20. The solenoid (23) is installed coaxially with the chain wheel (22),

체인휠(22)은 솔레노이드(23)의 내경측 상단부에서 통전시 자화되는 솔레노이드 자기력으로 솔레노이드(23)와 결합되도록 구성하고, The chain wheel 22 is configured to be coupled to the solenoid 23 by the solenoid magnetic force that is magnetized when energized at the upper inner diameter side of the solenoid 23,

정전시에는 체인휠(22)이 스프링(24) 탄발력으로 가바나패드(10)와 면접촉하는 클러치 작동으로 수동으로 체인을 통해 모터에 동력을 전달하도록 구성한다.In the event of a power outage, the chain wheel 22 is configured to manually transmit power to the motor through the chain through a clutch operation that makes surface contact with the gavana pad 10 using the elastic force of the spring 24.

이와 같이 구성한 본원발명은 전원이 연결된 상태에서는 솔레노이드(23)가 자화되어 체인휠(22)을 당기므로 스프링(24)은 압축된 상태를 이루고, 체인휠(22)과 가바나패드(10)는 동력전달 면접촉이 분리된다.In the present invention configured in this way, when the power is connected, the solenoid (23) is magnetized and pulls the chain wheel (22), so the spring (24) is in a compressed state, and the chain wheel (22) and gavana pad (10) are in a compressed state. The delivery and interview contacts are separated.

이 상태에서 정전이 되면, 솔레노이드(23)의 자기력이 없어지므로(도면에서 전원공급수단 및 작동스위치의 도시는 생략 함), 체인휠(22)은 도 4 의 실선상태에서 스프링(24)의 탄성 복원력에 의하여 점선상태로 위로 상승하여 가바나패드(10)와 면접촉으로 클러치 기능을 수행하게 된다.If a power outage occurs in this state, the magnetic force of the solenoid 23 disappears (illustration of the power supply means and operation switch is omitted in the drawing), so the chain wheel 22 has the elasticity of the spring 24 in the solid line state of FIG. 4. Due to the restoring force, it rises upward in a dotted line state and performs a clutch function through surface contact with the Gavana pad (10).

본 발명은 이렇게 정전시 체인휠(22)과 가바나패드(10)가 면접촉하는 클러치 작용상태에서 클러치하우징(20)의 체인공(25)으로 체인(6)이 통과되는 구성에 당김휠부(30)를 부가하였으므로, 체인휠(22)에 감겨진 체인(6)은 수평 상태에서 안정적으로 일조의 당김휠(31,32)에 의하여 수직으로 상승하거나 하강방향으로 하강하도록 작용한다. 이는 체인(6)에서 예를 들어 당김휠(31), 체인휠(22)을 거쳐 다시 다른 당김휠(32)을 지나 하강하도록 당김휠(32) 측 체인(6)을 당기면, 이는 도시하지 않은 셔터를 여는 쪽으로 기능하고, The present invention is a configuration in which the chain 6 passes through the chain hole 25 of the clutch housing 20 in a clutch action state in which the chain wheel 22 and the gavana pad 10 are in surface contact during a power outage, and the pull wheel portion 30 is provided. ) is added, so the chain (6) wrapped around the chain wheel (22) is stably raised vertically or lowered in a downward direction by a set of pulling wheels (31, 32) in a horizontal state. This is, for example, when the chain 6 on the side of the pull wheel 32 is pulled to descend from the chain 6 through the pull wheel 31, the chain wheel 22, and then the other pull wheel 32, which is not shown. Functions to open the shutter,

반대로 체인(6)에서 당김휠(32), 체인휠(22)을 거쳐 다시 다른 당김휠(31)을 지나 하강하도록 당김휠(31) 측 체인(6)을 당기면, 이는 도시하지 않은 셔터를 닫는 쪽으로 기능함을 예시할 수 있다.Conversely, if the chain (6) on the side of the pull wheel (31) is pulled to descend from the chain (6) through the pull wheel (32), the chain wheel (22), and then the other pull wheel (31), this closes the shutter (not shown). It can be exemplified that it functions as a side.

이렇게 수동으로 셔터를 열거나 닫을 경우, 체인(6)을 안내하는 체인휠(22)은 가바나패드(10)에 면접촉으로 동력을 전달하는 클러치 작용을 하도록 수동으로 모터(1)를 구동하고, 모터(1)의 회전축 구동은 감속기(2)에서 감속회전하고, 감속회전력은 드럼축공(3)에 축결합한 셔터드럼(4)을 수동으로 회전시키도록 작용한다.When manually opening or closing the shutter in this way, the chain wheel 22, which guides the chain 6, manually drives the motor 1 to act as a clutch to transmit power to the gavana pad 10 through surface contact, The rotation shaft of the motor (1) is driven to reduce rotation in the reducer (2), and the reduction rotation force acts to manually rotate the shutter drum (4) coupled to the drum shaft hole (3).

이렇게 셔터를 수동으로 열거나 닫을 필요가 있을 경우 당김 작용이나 풀림 작용하는 측의 체인(6)을 당기고, 당기는 힘은 체인휠(22)에서 하나의 당김휠(31)과 다른 당김휠(32)의 체인홈이 동일 위상 배열각도로 동기를 맞추어 축결합하도록 브라켓(33)에 설치되므로, 도르래 원리와 같이 정위치에서 힘이 동일하게 같은 위상각으로 분산되므로 당김 힘이 감소되어 약자도 쉽게 구동 가능하게 된다.When it is necessary to manually open or close the shutter in this way, the chain (6) on the pulling or releasing side is pulled, and the pulling force is generated from the chain wheel (22) by one pulling wheel (31) and the other pulling wheel (32). Since the chain grooves are installed on the bracket (33) to synchronize and engage the shaft at the same phase arrangement angle, the force is distributed equally at the same phase angle at the same position like the principle of a pulley, so the pulling force is reduced and even the weak can easily drive it. I do it.

아울러 모터(1)를 수직으로 설치하므로 셔터의 설치 공간이 수평 방식보다 줄어들고, 동력을 전달받는 방식도 모터의 회전축과 연결된 가바나패드(10)와 정전시 클러치 기능을 하는 체인휠의 면접촉으로 접촉이 용이하고, 체인휠에서는 체인이 수평으로 이동하다가 당김휠에서 수직으로 이동하므로 체인이 모터축과 나란하게 작용하고 체인공을 통하여 클러치 하우징 전면에 당김휠부가 직접 설치되므로 설치공간이 줄어든다.In addition, since the motor (1) is installed vertically, the installation space for the shutter is reduced compared to the horizontal method, and the method of receiving power is through surface contact between the gavana pad (10) connected to the rotation axis of the motor and the chain wheel that functions as a clutch in the event of a power outage. This is easy, and since the chain moves horizontally on the chain wheel and then vertically on the pull wheel, the chain acts in parallel with the motor shaft, and the pull wheel part is installed directly on the front of the clutch housing through the chain ball, reducing installation space.
