The chain 150 is provided with a chain tensioner 152 so that the chain 150 maintains tension. When the chain tensioner is installed, it is possible to prevent the chain 150 from being peeled off from the sprocket 132 or the idling sprocket 134.

상기 드럼(170)은 와이어(160)가 권취되고 출입문이 최대로 개방될 때 최상단의 슬랫(110)이 위치하는 곳과 천정의 내측방향으로 이격되어 배치된다. 상기 드럼(170)이 회전하면서 와이어(160)를 잡아 당김으로 슬랫(110)이 상승하게 된다. 상기 드럼(170)은 샤프트(130)와 평행하게 형성되며 별도의 구동모터(미도시)에 의해 회전되도록 구비된다. 하지만 상기 드럼(170)은 필요에 따라 별도의 구동모터 없이도 체인(150)을 구동하는 구동모터(140)에 연동하여 사용할 수 있음은 물론이다. 아울러 상기 드럼(170)에는 와이어(160)를 안내할 수 있도록 홈이 형성되는 것이 바람직하다. The drum 170 is disposed to be spaced apart from the place where the uppermost slat 110 is located when the wire 160 is wound and the door is opened to the maximum and in the inner direction of the ceiling. As the drum 170 rotates, the slat 110 rises by pulling the wire 160. The drum 170 is formed parallel to the shaft 130 and is provided to be rotated by a separate driving motor (not shown). However, the drum 170 can be used in conjunction with the driving motor 140 that drives the chain 150 without a separate driving motor as needed. In addition, it is preferable that a groove is formed in the drum 170 so as to guide the wire 160.

상기 와이어(160)는 드럼(170)에 권취되고 선단이 최하단의 슬랫(110)에 결합되어 슬랫(110)을 승강시킨다. 여기서 상기 와이어(160)에 가해지는 하중은 체인(150)보다 적은 보조적인 부하를 감당하도록 구비하는 것이 바람직하다. 상기 와이어는 상기 샤프트(160)의 외주면을 따라 이동한 후 드럼(170)에 권취된다.The wire 160 is wound around the drum 170 and the tip is coupled to the lowermost slat 110 to lift the slat 110. Here, the load applied to the wire 160 is preferably provided to bear an auxiliary load less than that of the chain 150. The wire is wound around the drum 170 after moving along the outer circumferential surface of the shaft 160.

상기 비틀림 스프링(180)는 상기 슬랫(110)의 상승시 자중에 의한 부하를 줄여주기 위하여 드럼(160)에 설치되며 상기 슬랫(110)이 상승하는 방향으로 비틀림이 작용하도록 설치된다. 상기 슬랫(110)의 부하를 경감하기 위해 상기 비틀림 스프링(180)을 사용하므로 종래의 웨이트를 사용할 경우 웨이트가 외부로 노출되어 외관을 해치는 문제점 또한 해결할 수 있다.The torsion spring 180 is installed on the drum 160 to reduce a load due to its own weight when the slat 110 rises, and is installed so that the torsion acts in a direction in which the slat 110 rises. Since the torsion spring 180 is used to reduce the load on the slat 110, when a conventional weight is used, the weight is exposed to the outside and the appearance is damaged.
