Description

롤 스크린의 텐션 조절장치{Roll screen of tension adjuster}Roll screen of tension adjuster

본 발명은 롤 스크린의 텐션 조절장치에 관한 것으로서, 보다상세하게는 롤 스크린의 몸체케이싱 양측단에 끼워지면서 내부 회전체와 결합되는 양측 마감측판 중 일측 마감측판의 내측에 회전체 내부의 토션스프링과 연결되는 원웨이부재를 일방향으로 회전가능하게 설치한 후, 상기 원웨이부재의 조절노브를 일측 마감측판의 외측으로 노출시킨 상태에서 조절노브 상의 조절홈에 간편히 드라이버 등을 끼워 원웨이부재를 일방향으로 회전시키는 간단한 조작으로 토션스프링의 텐션을 조절할 수 있도록 한 롤 스크린의 텐션 조절장치에 관한 것이다.The present invention relates to a tension adjusting device for a roll screen, and more specifically, a torsion spring inside the rotating body inside one of the finishing side plates of the two closing side plates coupled to the inner rotating body while being fitted to both ends of the body casing of the roll screen. After the one-way member is rotatably installed in one direction, the one-way member is simply inserted into the adjusting groove on the adjusting knob while the adjusting knob of the one-way member is exposed to the outside of one side finishing side plate. The present invention relates to a tension adjusting device of a roll screen, which enables to adjust the tension of a torsion spring by a simple operation of rotating it.

일반적으로 롤 스크린(블라인드, 방충망)은 창문이나 도어의 문틀 상부에 설치되어 내부와 외부를 차단하거나 여름철에 모기나 파리 등의 해충이 내부로 유입되지 못하게 차단하는데 사용하는 것으로, 상기의 롤 스크린 상측에는 블라인드나 방충망이 회전하면서 감기거나 풀리게끔 회전체가 설치된다.In general, the roll screen (blind, insect screen) is installed on the upper door frame of the window or door to block the inside and the outside, or to prevent pests such as mosquitoes or flies in the summer, the upper side of the roll screen The rotor is installed so that the blinds or insect screens are wound or unwound as they rotate.

그리고 블라인드나 방충망의 끝단에는 손잡이 바가 설치되어 손잡이 바를 하측으로 잡아당기게 되면 회전체 상에 감겨진 토션스프링의 텐션에 의해 블라인드와 방충망이 감기거나 풀리게 된다.And when the handle bar is installed at the end of the blind or the insect screen pulls the handle bar downward, the blind and the insect screen is wound or loosened by the tension of the torsion spring wound on the rotating body.

이와 같은 롤 스크린은 장시간 사용시 회전체 내부 토션스프링의 텐션이 약해지면서 권회속도가 느려져 블라인드나 방충망을 천천히 감아 올리게 되거나 멈춰서게 하는 현상이 발생 되고, 이와는 반대로 토션스프링의 텐션이 강하면 권회속도가 급속히 빨라져서 블라인드나 방충망이 순간적으로 감기면서 사용자를 놀라게 할 뿐 아니라 손잡이 바에 사용자의 손이 부딪칠 경우 부상을 입는 등의 안전사고를 유발케 되고, 또 손잡이 바가 창문이나 도어의 문틀 상부에 부딪치면서 심한 소음이 발생 되는 문제점이 있다.Such roll screen has a tendency that the tension of the torsion spring inside the rotating body becomes weak when it is used for a long time, causing the winding speed to be slowed up, causing the blind or the insect screen to be slowly wound up or stopped. Blinds or insect screens can wind up momentarily to surprise you and cause safety accidents such as injuries if your hands hit the handlebars. There is a problem that occurs.

따라서 이를 해결하기 위해 종래의 롤 스크린은 텐션이 약해진 토션스프링의 장력을 조절하기 위해서는 롤 스크린 전체를 창문이나 도어의 문틀 상부에서 떼어낸 상태에서 롤 스크린의 몸체케이싱 양측단에 끼워지는 양측 마감측판중 회전이 가능한 일측 마감측판을 손으로 잡고 회전시키거나, 또는 마감측판을 몸체케이싱에서 완전히 분리시킨 후, 별도의 도구를 이용하여 회전체 내부 토션스프링의 장력을 조절하여야 하므로, 매번 롤 스크린을 창문이나 도어의 문틀 상부에서 떼어냈다가 다시 부착하는 작업이 매우 힘들고 불편한 문제점이 있다.Therefore, in order to solve this problem, the conventional roll screen has two side finishing side plates which are fitted to both ends of the body casing of the roll screen in order to adjust the tension of the weakened torsion spring. Hold the rotatable one end side plate by hand and rotate it, or completely remove the finishing side plate from the body casing, and then use a separate tool to adjust the tension of the torsion spring inside the rotating body. Removing and reattaching from the upper door frame of the door is very difficult and inconvenient problem.
