본 고안은 방범 및 화재예방을 목적으로 설치되어 사용하는 셔터의 장애물 검출장치에 관한 것으로써, 좀더 구체적으로는 전동셔터의 무인 자동폐쇄시 셔터커튼의 하방에 장애물이 있을 경우 이를 검출하여 셔터커튼의 하강을 중단시키거나, 또는 초기 상태로 복귀시킨 다음 재동작시킬 수 있도록 한 것이다.The present invention relates to a shutter obstacle detection device installed and used for the purpose of crime prevention and fire prevention, more specifically, when there is an obstacle under the shutter curtain when the automatic shutter of the automatic shutter is closed, The descent can be stopped or restored to the initial state and then restarted.
일반적으로 무인제어나 원격조작을 하여 셔터커튼을 승,강시키는 전동셔터는 셔터커튼의 하강시 셔터커튼의 하방에 장애물이 위치되어 있어 셔터커튼의 하단면이 장애물과 맞닿을 경우 이를 감지하여 셔터커튼의 하강을 일시 중단시킨 다음 일정한 높이까지 상승시켜 정지시킨 후, 장애물이 제거될 때까지 셔터커튼을 재하강시키거나, 일정횟수 반복해서 셔터커튼을 승,하강시킨 다음 동작을 중단하는 안전장치를 구비하고 있다.In general, the electric shutter which raises or lowers the shutter curtain by unmanned control or remote operation is located under the shutter curtain when the shutter curtain is lowered. Therefore, when the bottom surface of the shutter curtain contacts an obstacle, the shutter curtain is detected. It is to be equipped with a safety device to suspend the descending of the suspension, raise it to a certain height, stop it, and then lower the shutter curtain until the obstacle is removed, or repeatedly lift and lower the shutter curtain a certain number of times. Doing.
첨부도면 제1도는 종래의 장치가 설치된 셔터의 구성도로써, 셔터가 설치될 출입구의 양측 내벽에 가이드레일(1)이 각각 수직으로 설치되어 있고 상기 출입구의 상측에는 셔터커튼(2)을 감아주거나, 풀어주는 권취샤프트(3)가 전동모터(4)의 구동에 따라 회전되도록 설치되어 있으며 상기 셔터커튼의 하단부에는 셔터커튼의 하강시 셔터커튼의 하강을 방해 또는 저지하는 장애물(5)을 검출하는 장애물 검출장치(6)가 고정되어 있다.1 is a configuration diagram of a shutter in which a conventional apparatus is installed, and guide rails 1 are vertically installed on both inner walls of entrances to which shutters are installed, and a shutter curtain 2 is wound around the entrances. , The winding shaft (3) to be released is installed to rotate in accordance with the driving of the electric motor (4) and at the lower end of the shutter curtain for detecting an obstacle (5) that prevents or prevents the falling of the shutter curtain when the shutter curtain is lowered The obstacle detecting device 6 is fixed.
상기 장애물 검출장치의 구성을 제2도를 참고로 살펴보면 다음과 같다.Looking at the configuration of the obstacle detecting apparatus with reference to Figure 2 as follows.
셔터커튼(2)의 하단부에 상기 셔터커튼의 길이방향 폭보다 좁게 시이드판(7)이 고정되어 있고 상기 시이드판의 일측에는 장애물의 검출에 따라 전동모터(4)의 구동을 제어하는 송신기(8)가 설치되어 있으며 상기 송신기에는 송신기를 동작시키는 누름스위치(9)가 시이드판()의 하부로 노출되게 끼워져 있다.A transmitter 8 is fixed to the lower end of the shutter curtain 2 to have a width narrower than the width of the shutter curtain in the longitudinal direction, and the transmitter 8 controls the driving of the electric motor 4 according to the detection of obstacles on one side of the sheath plate. Is installed, and the push switch 9 for operating the transmitter is fitted to be exposed to the bottom of the seed plate ().
그리고 상부 시이드판(7)의 하부에는 셔터커튼(2)의 하강시 셔터커튼의 하부에 장애물이 있을 경우 장애물과의 접촉으로 눌려지면서 송신기(8)의 누름스위치(9)를 눌러주는 누름판(10)이 일정범위(S)내에서 승,강하도록 결합되어 있다.In addition, when there is an obstacle in the lower part of the shutter curtain when the shutter curtain 2 descends, the lower plate of the upper guide plate 7 is pressed by contact with the obstacle and presses the push switch 9 of the transmitter 8 (10). ) Is combined to move up and down within a certain range (S).
이와같이 종래의 장치가 설치된 전동셔터는 전동모터(4)의 구동으로 권취샤프트(3)가 회전함에 따라 다수개의 연결편 또는 파이프가 고리형태로 연결된 셔터커튼(2)이 가이드레일(1)을 따라 승,하강하게 되는데, 출입구를 폐쇄하기 위해 전동모터(4)를 구동하여 권취샤프트(3)에 권취된 셔터커튼(2)을 하강시킬 때 상기 셔터커튼의 하부에 장애물(5)이 있을 경우에는 상기 장애물 검출장치(6)의 누름판(10)이 장애물(5)과 먼저 접속된다.In this way, the conventional shutter is equipped with a shutter curtain (2) in which a plurality of connecting pieces or pipes connected in a loop shape as the winding shaft (3) is driven by the driving of the electric motor (4) is raised along the guide rail (1). When the shutter curtain 2 wound on the winding shaft 3 is lowered by driving the electric motor 4 to close the entrance and exit, when there is an obstacle 5 under the shutter curtain, The pressing plate 10 of the obstacle detecting device 6 is first connected to the obstacle 5.
이러한 상태에서 전동모터(4)가 계속적으로 구동하여 권취샤프트(3)를 회전시키면 셔터커튼(2)이 하강하지만, 시이드판(7)에 일정범위만큼 승,강하도록 결합된 누름판(10)은 장애물에 걸려 하강하지 못하고 셔터커튼(2)의 하강되는 양만큼 반대로 상승하게 되므로 누름판(10)이 시이드판(7)의 하부로 노출된 누름스위치(9)를 눌러주게 된다.In this state, when the electric motor 4 is continuously driven and the winding shaft 3 is rotated, the shutter curtain 2 descends, but the pressing plate 10 coupled to the seed plate 7 to move up and down by a predetermined range is Since it does not fall down due to an obstacle and rises in the opposite direction as the descending amount of the shutter curtain 2 is pressed, the pressing plate 10 presses the push switch 9 exposed to the lower part of the seed plate 7.
이에따라 시이드판(7)의 일측에 설치된 송신기(8)가 동작되어 전동모터(4)의 구동을 원격 제어하게 되므로 전동모터(4)의 구동이 일시 정지된다.Accordingly, the transmitter 8 installed on one side of the seed plate 7 is operated to remotely control the driving of the electric motor 4, so that the driving of the electric motor 4 is temporarily stopped.
그러나 이러한 종래의 장치는 다음과 같은 문제점을 갖는다.However, this conventional apparatus has the following problems.
첫째, 시이드판(7)과 누름판(10사이의 공간부를 통해 물이 스며들거나, 습기가 침투하도록 되어 있어 동절기에 셔터커튼의 하강으로 시이드판과 누름판이 접속되고, 누름스위치가 상승된 상태에서 지면의 습기로 인해 이들의 접속면이 얼어 붙게 되므로 셔터커튼을 상승시킨 후, 출입구를 폐쇄시키기 위해 셔터커튼을 하강시 얼어 붙은 누름스위치 및 누름판이 동작되지 않게 되므로 장애물 검출장치의 하부에 장애물이 있더라도 장애물을 검출할 수 없게 되었다.First, the water penetrates through the space between the seed plate 7 and the pressing plate (10), or moisture penetrates, so that the seed plate and the pressing plate are connected by the lowering of the shutter curtain during the winter, and the ground of the push switch is raised. Due to the moisture, these connection surfaces are frozen, so after the shutter curtain is raised, the frozen push switch and the press plate are not operated when the shutter curtain is lowered to close the entrance and exit, so even if there is an obstacle under the obstacle detection device Could not be detected.
둘째, 가이드레일(1)에 고리형태로 연결된 셔터커튼(2)의 양측만 삽입 안내되고 장애물(5)을 검출하는 장애물 검출장치(6)의 시이드판(7)과 누름판(10)은 상기 가이드레일(1)에 안내되지 않기 때문에 누름판(10)의 하단면이 장애물(5)이나, 출입구의 바닥면에 맞닿는 과정에서 장애물 검출장치(6)가 내측(권취샤프트의 감김방향)으로 밀리는 현상이 자주 발생되어 장애물(5)이 있더라도 이를 검출하지 못하였다.Second, the guide plate (1) of the guide plate 1 is inserted into both sides of the shutter curtain (2) guided and the guide plate 7 and the pressing plate 10 of the obstacle detection device 6 for detecting the obstacle (5) is the guide Since the lower surface of the pressing plate 10 is in contact with the obstacle 5 or the bottom surface of the doorway because it is not guided by the rail 1, the phenomenon that the obstacle detecting device 6 is pushed inward (the winding direction of the winding shaft) is prevented. Frequently occurred, even if the obstacle (5) was not detected it.
특히, 파이프 셔터인 경우에는 셔터커튼(2)의 하강시 장애물 검출장치(6)가 말리는 현상이 더욱 자주 발생되었다.In particular, in the case of the pipe shutter, the phenomenon that the obstacle detecting device 6 dries when the shutter curtain 2 descends occurs more frequently.
이에따라 시이드판(7)과 누름판(10)이 장애물(5)을 검출하지 못하여 전동모터(4)가 계속적으로 구동하게 되므로 셔터커튼(2)이 가이드레일(1)에서 이탈되거나, 전동모터(4)가 소손되는 경우가 발생되었다.Accordingly, since the guide plate 7 and the pressing plate 10 do not detect the obstacle 5, the electric motor 4 is continuously driven, so that the shutter curtain 2 is separated from the guide rail 1 or the electric motor 4 ) Burned out.
셋째, 누름판(10)의 폭이 시이드판(7)의 폭보다 좁아 누름판이 시이드판의 내측에 위치되어 있어 제2도에 일점쇄선으로 도시한 바와 같은 경사면(5a)을 갖는 장애물(5)이 장애물 검출장치(6)의 하부에 있을 경우 누름판(10)이 장애물(5)과 접촉하지 못하고 시이드판(7)의 외측면이 먼저 닿아 전동모터(4)가 계속적으로 구동하게 되므로 셔터커튼(2)이 가이드레일(1)에서 이탈되거나, 전동모터(4)가 소손되는 경우가 발생되었다.Third, the width of the pressing plate 10 is narrower than the width of the seed plate 7 so that the pressing plate is located inside the seed plate so that the obstacle 5 having the inclined surface 5a as shown by the dashed-dotted line in FIG. When the lower portion of the obstacle detecting device 6 is located, the pressing plate 10 does not come into contact with the obstacle 5 and the outer surface of the sheath plate 7 first touches the electric motor 4 to continuously drive the shutter curtain 2. ) Is removed from the guide rail (1), or the electric motor (4) is burned out.
넷째, 셔터커튼(2)의 길이가 3m를 넘는 경우에는 금속의 비틀림현상으로 인해 누름판이 장애물과 접촉되더라도 누름스위치가 동작되지 않음으로 장애물을 검출하지 못하였다.Fourth, when the length of the shutter curtain (2) exceeds 3m, even if the pressing plate is in contact with the obstacle due to the twisting phenomenon of the metal, the push switch does not operate, the obstacle was not detected.
본 고안은 종래의 이와같은 문제점을 해결하기 위해 안출한 것으로써, 그 구조를 개선하여 셔터커튼의 하강시 장애물 검출장치가 말리는 현상을 제거함과 동시에 하우징과 승강부재 사이로 물기나 습기가 침투하더라도 장애물 검출장치가 정확히 동작되도록 하며, 경사면을 갖는 장애물도 정확히 검출할 수 있는 장치를 제공하는데 그 목적이 있다.The present invention has been devised to solve such problems in the related art, and its structure is improved to eliminate the phenomenon that the obstacle detecting device dries when the shutter curtain is lowered, and to detect obstacles even when water or moisture penetrates between the housing and the elevating member. It is an object of the present invention to provide a device that allows the device to operate correctly and to accurately detect an obstacle having an inclined surface.
상기 목적을 달성하기 위한 본 고안의 형태에 따르면, 가이드레일에 안내되어 승,하강하도록 셔터커튼과 동일 길이로 형성되어 최하부에 위치되는 셔터커튼에 고정됨과 동시에 내공간부의 양측으로 걸림턱이 형성된 하우징과, 상기 하우징에 형성된 걸림턱에 걸리는 상부플랜지 및 하우징의 하단면에 접속되는 하부플랜지를 갖으며 승,강 가능하게 내공간부에 결합됨과 동시에 상면에 적어도 1개 이상의 영구 자석이 고정된 승강부재와, 상기 하우징의 내공간부 상측에 각 영구자석과 대응되게 고정되어 승강부재가 상승함에 따라 영구자석의 자장에 의해 장애물을 감지하는 리드 스위치와 상기 하우징의 상부 일측에 고정되어 리드 스위치가 동작됨에 따라 신호를 전동모터에 전달하여 전동모터의 구동을 제어하는 송신기로 구성된 셔터의 장애물 검출장치가 제공된다.According to a form of the present invention for achieving the above object, the guide rail is formed in the same length as the shutter curtain so as to move up and down, fixed to the shutter curtain located at the bottom and at the same time the housing is formed with a locking jaw on both sides of the inner space portion And an elevating member having an upper flange and a lower flange connected to a lower surface of the housing formed on the locking jaw formed in the housing and being coupled to the inner space so as to be lifted and lowered and at least one permanent magnet fixed to the upper surface. And a reed switch for detecting an obstacle by the magnetic field of the permanent magnet as the elevating member is lifted to correspond to each permanent magnet on the upper portion of the inner space of the housing and a signal as the reed switch is fixed to the upper one side of the housing.

상기 승강부재(16)의 하부 양측에 상기 승강부재의 상단면에서부터 리드스위치(19)까지의 거리(a)보다, 하우징(11)의 하단면에서부터 승강부재(16)의 하부플랜지(15)상면까지의 거리(b)가 짧게 하부플랜지(15)만 형성하여도 셔터의 하강시 상기 승강부재의 하부에 위치되는 장애물(5)을 감지할 수 있지만, 장기간 사용으로 하부플랜지(15)가 제4도에 도시한 일점쇄선과 같이 하방으로 변형되어 상기 승강부재의 상단면에서부터 리드스위치(19)까지의 거리(a)보다, 하우징(11)의 하단면에서부터 승강부재(16)의 하부플랜지(15)상면까지의 거리(b)가 길어지게 될 경우에는 승강부재(16)의 상단면이 리드스위치(19)까지의 거리(a)보다 더 상승하여 리드스위치(19)와 부딪힐 염려가 있게 된다.The upper surface of the lower flange 15 of the elevating member 16 from the lower surface of the housing 11 than the distance a from the upper surface of the elevating member to the reed switch 19 on both lower sides of the elevating member 16. Even if the distance b is short, only the lower flange 15 may be formed to detect the obstacle 5 located at the lower portion of the elevating member when the shutter descends. The lower flange 15 of the elevating member 16 from the lower end surface of the housing 11 than the distance a from the upper end surface of the elevating member to the reed switch 19 as shown in FIG. When the distance b to the upper surface becomes longer, the upper end surface of the elevating member 16 is raised higher than the distance a to the reed switch 19, so that there is a risk of colliding with the reed switch 19. .
이에따라 본 고안의 일 실시예에서는 하우징(11)에 형성된 걸림턱(13)의 하부로 승강부재의 상단면에서부터 리드스위치(19)까지의 거리(a)보다는 짧고, 하우징(11)의 하단면에서부터 승강부재(16)의 하부플랜지(15) 상면까지의 거리(b)보다는 긴 일정간격(c)이 유지되도록 상기 승강부재(16)에 절곡부(21)를 형성하여 상기 하부플랜지(15)가 하향 변형시 상기 절곡부가 하우징(11)에 형성된 걸림턱(13)에 걸려 승강부재(16)의 과잉상승을 제어하도록 되어 있다.Accordingly, in one embodiment of the present invention is shorter than the distance (a) from the upper surface of the elevating member to the reed switch 19 to the lower portion of the locking projection 13 formed in the housing 11, from the lower surface of the housing 11 The lower flange 15 is formed by forming a bent portion 21 on the elevating member 16 so that a predetermined distance c is maintained longer than the distance b to the upper surface of the lower flange 15 of the elevating member 16. When the downward deformation, the bent portion is caught by the locking step 13 formed in the housing 11 to control the excessive rise of the elevating member 16.
상기한 리드스위치(19)와 영구자석(17)은 셔터커튼(2)의 길이에 따라 적절한 갯수로 설치되는 것이 바람직하다.The reed switch 19 and the permanent magnet 17 is preferably installed in an appropriate number according to the length of the shutter curtain (2).
이는 셔터커튼(2)의 길이가 길어짐에 따라(약 3m 이상) 승강부재(16)가 장애물을 감지하더라도 금속의 비틀림현상으로 장애물을 감지하지 못하던 종래의 문제점을 해결하기 위함이다.This is to solve the conventional problem of failing to detect the obstacle due to the twisting of the metal even if the lifting member 16 detects the obstacle as the length of the shutter curtain (2) is longer (about 3m or more).
그리고 상기 하우징(11)의 상부 일측(건물의 내측)에는 하우징에 고정된 리드스위치(19)가 영구자석(17)의 자장으로 동작됨에 따라 신호를 전동모터(4)에 전달하여 상기 전동모터의 구동을 제어하는 송신기(8)가 설치되어 있다.And the upper side of the housing 11 (inside of the building) as the reed switch 19 fixed to the housing is operated as a magnetic field of the permanent magnet 17 transmits a signal to the electric motor (4) of the electric motor The transmitter 8 which controls a drive is provided.
한편, 하우징(11)의 저면과 승강부재(16)의 상면사이에는 압축스프링과 같은 탄성부재(22)가 설치되어 있어 셔터커튼(2)의 상승시 탄성부재의 복원력에 의해 승강부재(16)를 하강하도록 되어 있다.On the other hand, between the bottom of the housing 11 and the upper surface of the elevating member 16 is provided with an elastic member 22 such as a compression spring, the elevating member 16 by the restoring force of the elastic member when the shutter curtain (2) is raised. Is supposed to descend.
이는 동절기에 출입구가 폐쇄된 상태에서 승강부재(16)에 형성된 하부플랜지(15)가 하우징(11)의 하단면에 접속되어 얼어 붙더라도 셔터커튼(2)의 상승시 승강부재(16)를 탄성부재(22)의 복원력에 의해 하우징(11)의 하부로 노출되도록 하므로서 오동작이 발생되는 것을 미연에 방지하기 위함이다.This is because even if the lower flange 15 formed on the elevating member 16 in the state in which the entrance is closed in winter is connected to the lower surface of the housing 11 and frozen, the elevating member 16 is elastic when the shutter curtain 2 is raised. This is to prevent the occurrence of a malfunction by being exposed to the lower portion of the housing 11 by the restoring force of the member 22.
이와같이 구성된 본 고안의 작용, 효과를 설명하면 다음과 같다.Referring to the operation, effects of the present invention configured as described above are as follows.
먼저, 출입구를 폐쇄하기 위해 전동모터(4)에 전원을 인가하면 상기 전동모터의 출력축과 고정된 권취샤프트(3)가 회전하게 되므로 상기 권취샤프트에 권회된 셔터커튼(2)이 하강하게 된다.First, when power is applied to the electric motor 4 to close the entrance and exit, the winding shaft 3 fixed to the output shaft of the electric motor rotates, so that the shutter curtain 2 wound on the winding shaft is lowered.
이와같이 셔터커튼(2)이 점진적으로 하강하면 상기 셔터커튼은 출입구의 양측으로 수직되게 고정된 가이드레일(1)에 안내됨과 동시에 상기 셔터커튼의 최하방에 고정된 하우징(11)과 승강부재(16)도 가이드레일(1)에 안내되므로 셔터커튼(2)과 본 고안의 장치가 보다 안정적으로 하강하게 된다.When the shutter curtain 2 is gradually lowered as described above, the shutter curtain is guided to the guide rails 1 fixed vertically to both sides of the entrance and at the same time, the housing 11 and the elevating member 16 fixed to the lowermost side of the shutter curtain. ) Is also guided to the guide rail (1), the shutter curtain (2) and the device of the present invention is lowered more stably.
이렇게 셔터커튼(2)이 하강될 때 승강부재(16)의 하방에 장애물(5)이 있을 경우에는 상기 승강부재의 하단면이 장애물과 접촉된 상태에서 셔터커튼(2)이 계속해서 하강하게 되므로 하우징(11)의 하부로 노출되어 있던 승강부재(16)가 탄성부재(22)를 압축시키면서 상승하게 된다.When there is an obstacle 5 below the elevating member 16 when the shutter curtain 2 is lowered in this way, the shutter curtain 2 continuously descends while the bottom surface of the elevating member is in contact with the obstacle. The elevating member 16 exposed to the lower portion of the housing 11 rises while compressing the elastic member 22.
상기 승강부재(16)의 하단면이 장애물(5)과 접촉될 때 제4도에 일점쇄선으로 도시한 장애물(5)과 같이 경사면(5a)이 형성되어 있더라도 승강부재(16)의 폭이 하우징(11)의 폭과 동일하게 되어 있어 반드시 승강부재가 장애물(5)과 먼저 접촉되어 상승하게 된다.When the bottom surface of the elevating member 16 is in contact with the obstacle 5, even if the inclined surface 5a is formed like the obstacle 5 shown by the dashed line in FIG. It is equal to the width of (11) so that the elevating member is first in contact with the obstacle (5) to rise.
이와같이 승강부재(16)가 상승하면 상기 승강부재의 상부면에 적어도 1개 이상 고정된 영구자석(17)이 하우징(11)의 하단면에 고정된 리드스위치(19)를 동작시키게 되므로 송신기(8)에서 전동모터(4)에 신호를 전달하게 되고, 이에따라 전동모터의 구동을 중단시키게 된다.As such, when the elevating member 16 is raised, at least one permanent magnet 17 fixed to the upper surface of the elevating member operates the reed switch 19 fixed to the lower surface of the housing 11. The signal is transmitted to the electric motor (4), thereby stopping the driving of the electric motor.
또한, 동절기에 하우징(11)의 하단면과 하부플랜지(15)가 얼어 붙더라도 하우징(11)의 저면과 승강부재(16)의 상면사이에는 탄성부재(22)가 설치되어 있어 셔터커튼(2)의 상승시 승강부재(16)를 하방으로 노출시키게 되므로 셔터커튼의 하강시 장애물을 정확히 감지하게 된다.In addition, even if the bottom surface of the housing 11 and the lower flange 15 is frozen in winter, the elastic member 22 is provided between the bottom surface of the housing 11 and the upper surface of the elevating member 16, so that the shutter curtain 2 Since the elevating member 16 is exposed downward when the) is raised, obstacles are accurately sensed when the shutter curtain is lowered.
한편, 장기간 반복사용으로 하부플랜지(15)가 제4도의 일점쇄선과 같이 하방으로 변형되어 (b)의 간격이 (a)의 간격보다 멀어지게 되더라도 상기 승강부재(16)에는 걸림턱(13)과 (c)간격을 유지하도록 절곡부(21)가 형성되어 있어 승강부재(16)의 상단면이 리드스위치(19)와 충돌하는 것을 방지하게 된다.On the other hand, even if the lower flange 15 is deformed downward as shown by the dashed-dotted line of FIG. 4 due to repeated use for a long time, even if the interval of (b) becomes farther than the interval of (a), the lifting jaw (13) is caught on the lifting member (16). And (c) the bent portion 21 is formed to maintain the interval to prevent the upper surface of the elevating member 16 from colliding with the reed switch (19).
이상에서와 같이 본 고안은 다음과 같은 장점을 갖게 된다.As described above, the present invention has the following advantages.
첫째, 하우징(11)과 승강부재(16)사이의 공간부를 통해 내공간부(12)로 물이 스며들거나, 습기가 침투하여 동절기에 하우징의 하단면과 승강부재의 하부플랜지가 얼어 붙더라도 내공간부내에 승강부재를 하강시키는 탄성부재가 설치되어 있으므로 셔터커튼을 상승시 상승부재가 하우징의 하부로 노출되고, 이에따라 승강부재의 하부에 장애물이 있을 경우에는 정확히 장애물을 감지하여 전동모터의 구동을 중단하게 된다.First, the inner space portion even if water penetrates into the inner space portion 12 through the space portion between the housing 11 and the elevating member 16, or moisture penetrates and the bottom flange of the housing and the lower flange of the elevating member are frozen in winter. Since there is an elastic member for lowering the elevating member, the elevating member is exposed to the lower part of the housing when the shutter curtain is raised. As a result, when there is an obstacle in the lower part of the elevating member, the elevating member is correctly sensed to stop driving of the electric motor. do.
둘째, 가이드레일(1)에 고리형태로 연결된 셔터커튼(2)과 승강부재(16)가 결합된 하우징(11)의 양단이 동시에 삽입되어 안내되므로 파이프셔터인 경우에도 셔터커튼의 하강시 장애물 검출장치가 내측(권취샤프트의 감김방향)으로 말리는 현상이 발생되지 않게 되고, 이에따라 장애물(5)을 검출하지 못하여 전동모터(4)가 계속적으로 구동하는 것을 미연에 방지하게 된다.Second, since both ends of the housing 11 coupled with the shutter curtain 2 and the elevating member 16 coupled to the guide rail 1 are inserted and guided at the same time, obstacles are detected when the shutter curtain is lowered even in the case of a pipe shutter. The phenomenon in which the device curls inwardly (the winding direction of the winding shaft) does not occur, thereby preventing the obstacle 5 from being detected, thereby preventing the electric motor 4 from being continuously driven.
셋째, 승강부재(16)의 폭이 하우징(11)의 폭과 동일하게 형성되어 있어 경사면(5a)을 갖는 장애물(5)이 있을 경우에도 반드시 승강부재가 장애물과 먼저 접촉하여 장애물을 감지하게 되므로 기기의 신뢰성을 향상시키게 된다.Third, since the width of the elevating member 16 is formed to be the same as the width of the housing 11, even when there is an obstacle 5 having the inclined surface 5a, the elevating member must first contact the obstacle to detect the obstacle. Improve the reliability of the device.
넷째, 셔터커튼의 길이가 3m를 넘어 장애물의 검출시 금속의 비틀림현상이 발생되더라도 셔터커튼의 길이에 비례하여 1개 이상의 리드스위치와 영구자석이 설치되어 있으므로 장애물을 정확히 검출하게 된다.Fourth, even if the length of the shutter curtain is more than 3m, when the twisting of the metal occurs when the obstacle is detected, one or more reed switches and permanent magnets are installed in proportion to the length of the shutter curtain, so that the obstacle is accurately detected.
