Description
본 고안은 롤 스크린에 관한 것으로, 특히 창문을 이중으로 가릴 수 있는 이중 롤 스크린에 관한 것이다.The present invention relates to a roll screen, and more particularly to a double roll screen that can double the window.
일반적으로 유리창에 부착되는 썬팅 필름은 그 종류에 따라 내부에서는 외부를 볼 수 있지만 외부에서는 내부를 볼 수 없게 하는 기능이 있고, 자외선을 차단하거나, 외부로 들어오는 조도를 감소시켜 실내의 눈부심 제거 등의 기능도 한다.Generally, the tinting film attached to the glass window has the function to make the inside visible from the outside, but not to see the inside from the outside, and to remove the glare in the room by blocking the ultraviolet rays or reducing the intensity of light coming in from the outside. It also functions.
상기한 필름의 기능중 내부에서 외부를 볼 수 있지만 외부에서 내부를 볼 수 없게 하는 단방향 필름은 조도차이에 따른 기능으로써 태양빛에 의해 주간에는 외부의 조도가 내부 보다 높아 상기한 기능을 할 수 있지만 야간에는 반대의 현상이 발생된다. 따라서 야간에는 사생활 보호 등을 위하여 별도의 커튼을 설치해야 한다.Among the functions of the film, the unidirectional film which can see the inside from the outside but cannot see the inside from the outside is a function according to the illuminance difference. The opposite happens at night. Therefore, at night, a separate curtain must be installed for privacy protection.
그리고, 창문에 양방향 불투명 썬팅 필름을 적용하면 조도와 관계없이 내외부 양측에서 상호 반대측으로 보는 것이 차단되나 이렇게 되면 창문의 기능이 상당 부분 상실되어 버린다. 즉 유리창은 주간에 태양빛을 받아 들여 내부를 가온시킴으로써 에너지 절약기능도 하는데 양방향 불투명 필름이 부착되어 있으면 그 기능이 현저히 떨어진다. In addition, when a bidirectional opaque tinting film is applied to a window, viewing from opposite sides is blocked from both inside and outside regardless of illuminance, but this causes a substantial loss of function of the window. In other words, the glass window is also energy-saving by receiving sunlight in the daytime and warming the inside.
이와 같이 창문에 부착되는 썬팅 필름은 사생활 보호, 자외선 차단 기능을 하지만 창문의 본래 기능중 하나인 태양빛을 받아들여 실내를 가온시키는 에너지 절약기능을 약화시키고, 썬팅 필름의 기능도 조도 등의 외부 조건에 따라 적절히 수행할 수 없게 된다.As described above, the tinting film attached to the window protects privacy and UV rays, but it weakens the energy saving function of warming the room by receiving sunlight, which is one of the original functions of the window. In some cases, it cannot be performed properly.
본 고안은 전술한 바와 같은 문제점을 해결하기 위한 것으로, 썬팅 필름을 유리창에 부착시키지 않고, 유리창 전면에 롤 스크린과 같이 사용자가 감았다 펼 수 있게 함으로써 외부 조건에 따라 선택적으로 조정하는 이중 롤스크린을 제공하는 데 그 목적이 있다. The present invention is to solve the problems described above, to provide a dual roll screen to selectively adjust according to the external conditions by allowing the user to wind and unwind like a roll screen on the front of the glass window without attaching the tinting film to the glass window Its purpose is to.

전술한 바와 같이 본 고안의 구성에 따른 작용을 설명하면 다음과 같다.Referring to the operation according to the configuration of the present invention as described above are as follows.
이중 롤 스크린의 설치대(110)를 고정쇠(112)를 이용하여 유리창 상단의 창틀에 고정시킨다.The mounting roll 110 of the double roll screen is fixed to the window frame at the top of the glass window by using the clamp 112.
이중 롤 스크린이 창틀에 고정된 상태에서 제1구동장치(140)에 설치된 일측 제1볼체인(210)을 잡아당기면 구동장치가 반시계방향으로 회전하면서, 제1회전봉(170)이 반시계 방향으로 회전하고 이때 제1회전봉(170)에 감겨진 양쪽 방향 불투명인 양방향 필름(190)이 풀리면서 유리창에 상하로 펼쳐진다. 즉 유리창을 가리에 되어 외부에서 내부를, 내부에서 외부를 볼 수 없게 된다. 반대로 다른 일측 제1 볼체인(210)을 잡아당기면 제1구동장치(140)가 시계방향으로 회전하면서 제1회전봉(170)이 시계방향으로 회전하고, 이때 풀렸던 양방향 필름(190)이 감기면서 유리창이 개방된다. 그리고 양방향 필름의 양측단에 형성된 압축고무(194)를 눌러 유리창에 붙이면 부압에 의하여 달라붙게 되므로 양방향 필름(190)이 바람 등에 의하여 펄럭이는 것이 방지된다.Pulling the first ball chain 210 on one side of the first driving device 140 while the dual roll screen is fixed to the window frame, the driving device rotates counterclockwise, and the first rotating rod 170 counterclockwise. Rotate to and the two-way opaque bi-directional film 190 wound around the first rotating rod 170 is unfolded while spreading up and down on the glass window. In other words, the glass window is covered by the window, and the inside cannot be seen from the outside. On the contrary, when the first ball chain 210 is pulled on the other side, the first driving device 140 rotates clockwise while the first driving device 140 rotates clockwise, and at this time, the unwinding bidirectional film 190 is wound. The window opens. In addition, when the compression rubber 194 formed at both ends of the bidirectional film is pressed and attached to the window, the bidirectional film 190 is prevented from fluttering due to wind or the like.
이중 롤 스트린이 창틀에 고정된 상태에서 제2구동장치(160)에 설치된 일측제2볼체인(220)을 잡아당기면 제2구동장치(160)가 반시계 방향으로 회전하면서 제2회전봉(180)이 동일한 방향으로 회전하고 이때 제2회전봉(180)에 감긴 단방향 필름(200)이 풀리면서 유리창에 상하로 펼쳐진다. 즉 유리창을 가리게 되어 주간에 상당량의 빛은 투과되지만 조도가 높은 외부에서 조도가 낮은 내부는 볼 수 없게 된다. 반대로 다른 일측 제2볼체인(220)을 잡아당기면 제2구동장치(160)가 시계방향으로 회전하면서 제2회전봉(180)이 시계방향으로 회전하고 이때 풀렸던 단방향 필름(200)이 감기면서 유리창이 개방된다.Pulling the one side second ball chain 220 installed in the second driving device 160 while the double roll screen is fixed to the window frame, the second driving device 160 rotates in the counterclockwise direction and the second rotating rod 180 Rotate in the same direction and at this time, the unidirectional film 200 wound around the second rotating rod 180 is unfolded and spread up and down on the glass window. In other words, the window is covered so that a considerable amount of light is transmitted during the day, but the inside of the low light is not visible from the outside of the high light. On the contrary, when the second ball chain 220 is pulled on the other side, the second driving device 160 rotates in the clockwise direction, and the second rotating rod 180 rotates in the clockwise direction. Is opened.
상기한 바와 같이 본 고안은 유리창을 가리는 이중 필름을 사용자의 필요에 따라 볼체인을 잡아당김으로써 선택적으로 펴거가 감을 수 있는 것이다.As described above, the present invention can selectively unwind and wind the double film covering the glass window by pulling the ball chain according to the user's needs.
상기한 바와 같이 본 고안에 따른 이중 롤 스크린은 단방향 필름과 양방향 필름이 일체로 설치되어 있고, 상기 두 개의 필름을 선택적으로 펴거나 감음으로써 조도 등 외부환경에 따라 적절하게 유리창을 가릴 수 있다. As described above, the dual roll screen according to the present invention is integrally installed with the unidirectional film and the bidirectional film, and can selectively cover the window according to the external environment such as roughness by selectively spreading or winding the two films.
