Lifting device for blinds {Up-down apparatus for blind}

본 발명은 블라인드용 승강장치에 관한 것으로서, 보다 상세하게는 실내의 보안 및 차양을 위해 창문에 설치되는 블라인드의 승강시 적은 힘으로도 복수개의 슬레이트로 구성된 블라인드를 승강시킬 수 있도록 한 블라인드용 승강장치에 관한 것이다.The present invention relates to a lifting device for blinds, and more specifically, a blind lifting device for lifting and lowering a blind composed of a plurality of slats with little force during lifting of a blind installed in a window for security and awning of a room. It is about.

주지하는 바와 같이 건물의 창 내측에 설치되어 수동으로 작동되거나, 또는 모터를 이용한 자동화 장치에 의해 작동되는 블라인드는 소정의 폭과 길이를 갖는 다수개의 슬레이트를 일정 간격을 두고 설치한 상태에서 슬레이트를 승강시키거나 또는 슬레이트의 경사 각도를 조절함으로써, 사생화 보호와 난방 및 채광량을 조절하는 기능을 수행하게 된다. As is well known, blinds installed inside a window of a building and operated manually, or operated by an automated device using a motor, lift and lower the slats with a plurality of slats having a predetermined width and length spaced at regular intervals. By adjusting the angle of inclination of the slats or by controlling the inclination of the slats, and controlling the amount of heating and light.

상기한 블라인드는 수직형 블라인드와 수평형 블라인드로 대분할 수 있다.The blinds can be divided into vertical blinds and horizontal blinds.

즉, 상기한 수직형 블라인드는 소정의 폭과 길이를 갖는 복수개의 슬레이트들이 수직으로 구비되는 구조이고, 상기한 수평형 블라인드는 소정의 폭과 길이를 갖는 복수의 슬레이트들이 수평으로 구비되는 구조이다.That is, the vertical blind has a structure in which a plurality of slats having a predetermined width and length are provided vertically, and the horizontal blind has a structure in which a plurality of slats having a predetermined width and length are provided horizontally.

상기한 수직 및 수평형 블라인드는 승강장치의 승강수단에 연결되어 구비되는 작동용 와이어의 조작에 대응되게 슬레이트에 연결된 슬레이트용 와이어가 권취수단에 감김 및 풀림됨으로써 복수개의 슬레이트들을 일방향으로 펼치거나 겹쳐지게 감기도록 하여 블라인드를 개폐시키게 된다.The vertical and horizontal blinds are wound or unrolled in one direction by winding and unwinding a plurality of slats in one direction by winding and unwinding a slate wire connected to the slate in response to an operation of an operation wire provided connected to a lifting means of a lifting device. To open and close the blind.

즉, 종래의 일반적인 수평형 블라인드용 승강장치는 천정 또는 벽체 상부에 고정 구비되는 하우징의 내부에 회전가능하게 설치되는 회전부재를 갖는 승강수단과, 상기 승강수단에 연결되어 상기 승강수단을 회전시키도록 구비되는 작동용 와이어와, 상기 승강수단의 일측에는 작동축에 의해 승강수단의 회전부재와 연결되어 상기 작동용 와이어의 조작에 대응되게 회전가능하게 구비되는 권취수단과, 상기 권취수단에 일단이 고정 연결되고, 타단은 상기 슬레이트에 연결되어 구비되는 슬레이트 승강용 와이어로 이루어진다.That is, the conventional general horizontal lifting device for a blind has elevating means having a rotating member rotatably installed in the interior of the housing fixed to the ceiling or wall upper portion, and is provided to rotate the elevating means connected to the elevating means And a winding wire which is connected to the rotating member of the lifting means by an operating shaft on one side of the lifting means, and is rotatably provided to correspond to the operation of the operating wire, and one end is fixedly connected to the winding means. And, the other end is made of a slate lifting wire which is connected to the slate provided.
