일반적으로 대형공장 내에서는 작업 중에 발생하는 오염된 공기를 환기시켜 작업환경을 개선하기 위하여 수시로 환기창문을 열고 실내 오염된 공기를 환기시켜야 하는바, 작업중에 발생하는 오염된 공기는 실내 바닥면에서부터 천정인 상부로 올라가기 때문에 환기창문을 대부분 천정에 근접하는 양 측면에 위치시켜 설치하고 지상에서 스위치 등의 조작으로 개폐시키고 있다.In general, in large factories, in order to ventilate the polluted air generated during the work to improve the working environment, open the ventilation windows and ventilate the indoor polluted air from time to time. Since it rises to the upper part of the room, the ventilation windows are installed on both sides close to the ceiling, and are opened and closed on the ground by a switch or the like.

이러한 종래의 환기창문은 감속모터에 의한 체인 또는 로프 구동방식으로 구성됨에 따라 그 구조가 매우 복잡하여 고장발생률이 높을 뿐 아니라 고장이 나면 수리 및 보수가 불편하였고, 특히 모터 식의 경우는 전기배선을 해야하기 때문에 누전이나 기타 전기사고 등이 일어날 위험성이 컸으며, 곧 정전이 되었을 경우는 환기창문의 개폐가 불가능하게 되는 문제점이 있다.Since the conventional ventilation window is composed of a chain or rope driving method by a reduction motor, the structure thereof is very complicated and the failure rate is high. Because of the need to short-circuit or other electrical accidents were a great risk, if there is a power outage, there is a problem that opening and closing of the ventilation window is impossible.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 본 발명은 공기압을 이용한 에어 실린더로 구성함으로써 구조가 간단하고 고장의 발생을 최소화한 에어실린더를 이용한 창문 개폐장치를 제공하는데 목적이 있다.The present invention is to solve the above problems, it is an object of the present invention to provide a window opening and closing device using an air cylinder with a simple structure and minimized the occurrence of failure by configuring the air cylinder using the air pressure.

The end of the rod 17 inserted into the inner side is provided with a piston 15 having a packing member 6 coupled to the circumferential surface.

따라서, 종래에 금속으로 제조된 전체 밀폐방식의 고가의 에어실린더를 사용하지 않고, 합성수지에 의해 간단하게 구현할 수 있다.Therefore, it is possible to simply implement by a synthetic resin, without using a conventional hermetic expensive air cylinder made of a metal.

그리고, 상기 로드(17)에는 도 2b에서 도시한 바와 같이 이동부재(18)가 볼트(18b)에 의해 견고히 결합되어 로드(17)와 함께 이동할 수 있게 구성되어 있는데, 상기 이동부재(18)의 양단에는 이동시 좌·우측 실린더(10)(20)와의 충돌이 있을 경우 충격을 흡수하기 위한 소정 두께의 완충부(18a)가 형성되어 있으며, 이 완충부(18a)와 이동부재(18) 사이에는 와셔(18c)가 결합되어 있다.In addition, as shown in FIG. 2B, the moving member 18 is firmly coupled by the bolt 18b and configured to move together with the rod 17. At both ends, a shock absorbing portion 18a having a predetermined thickness is formed to absorb a shock when there is a collision with the left and right cylinders 10 and 20 during movement, and between the shock absorbing portion 18a and the moving member 18. The washer 18c is engaged.

상기 완충부(18a)는 연질의 합성수지, 목재로도 구성할 수도 있으나 마모가 잘 되지 않는 경질의 고무로 구성하는 것이 가장 바람직하다.The buffer portion 18a may be made of soft synthetic resin and wood, but most preferably, hard rubber is hardly worn.

한편, 상기 좌·우측 실린더(10)(20)의 끝단에는 로드(17)를 작동시키기 위한 에어가 공급되거나 배출되는 좌·우측 호스(33)(34)가 각각 연결되어 있는데, 상기 좌·우측 호스(33)(34)의 타단은 사용자가 임의로 조작할 수 있도록 핸들(31)이 구비된 전환밸브(30)에 연결되어 있다.Meanwhile, left and right hoses 33 and 34 to which air for operating the rod 17 is supplied or discharged are connected to ends of the left and right cylinders 10 and 20, respectively.
