이와 같이 구성된 본 발명의 수직개폐 도어의 급강하 방지장치의 작용을 첨부한 도 3에 의해 이하에서 상세하게 기술하기로 한다. The operation of the dive prevention device of the vertical opening and closing door of the present invention configured as described above will be described in detail below with reference to FIG. 3.

롤업 도어, 스태킹 도어, 및 오버헤드 도어 등의 산업용 수직개폐 도어가 개폐를 위해 승강시에 레일(20)을 따라 승강되는 슬라이더(30)에 설치된 진자추(40)의 롤러(41)가 라운드형 돌기(50)를 올라타고 넘으면서 걸림구멍(60)으로 삽입되었다가 빠져나오게 되는데, 이때, 상기 진자추(40)는 유동가능하게 고정설치된 그 상단이 좌우로 움직이면서 그 하단이 원호를 그리게 된다. The roller 41 of the pendulum 40 installed on the slider 30 which is lifted along the rail 20 at the time of lifting up and down for industrial opening and closing doors such as a rollup door, a stacking door, and an overhead door is rounded. The pendulum 40 is inserted into the locking hole 60 while coming up and exiting the protrusion 50, and the pendulum 40 moves to the left and right while being fixedly movable, and the lower end thereof draws an arc.

이렇게 하단이 좌우로 움직이면서 원호를 그리는 진자추(40)는 도 3에 도시된 바와 같이, 상기 도어가 정상적인 속도로 정속강하시에는 진자추(40)의 롤러(41)가 라운드형 돌기(50)를 자연스럽게 올라타고 내려오면서 진자추(40)의 하단 이 그리는 원호가 작기 때문에 걸림구멍(60)으로 진자추(40)의 걸림돌기(42)가 삽입되더라도 탄성와이어(43)의 절곡부(431)가 돌출핀(31)을 올라타고 넘지 못하기 때문에 걸림돌기(42)가 삽입되어 있던 걸림구멍(60)에서 빠져나오게 된다. As shown in Figure 3, the pendulum pendulum 40 which draws an arc while moving the lower end to the left and right, the roller 41 of the pendulum 40 is a round projection 50 when the door is constant speed at a normal speed Since the circular arc drawn by the bottom of the pendulum 40 is small while riding up and down naturally, even when the engaging protrusion 42 of the pendulum 40 is inserted into the engaging hole 60, the bent portion 431 of the elastic wire 43 Does not pass over the protruding pins 31, so that the locking protrusions 42 escape from the locking holes 60 into which the locking protrusions 42 have been inserted.

그러나 상기 도어가 비정상적인 속도로 급속강하시, 즉 도어의 개폐시에 승강용 와이어 로프나 체인이 끊어져 도어가 급속강하하게 되면 진자추(40)의 롤러(41)가 라운드형 돌기(50)를 자연스럽게 올라타고 내려오는 것이 아니라 순간적으로 라운드형 돌기(50)에 롤러(41)가 부딪히면서 생기는 힘에 의해 진자추(40)가 원호를 크게 그리기 때문에 탄성와이어(43)의 절곡부(431)가 돌출핀(31)을 순간적으로 올라타게 되는데, 이때 롤러 회전축 구멍(411)에 여유있게 끼워져 있던 탄성와이어(43)의 타단이 탄성에 의해 롤러 회전축 구멍(411) 내에서 롤러 회전축 구멍(411)의 원래 위치에서 다른 위치로 밀리면서 절곡부(431)가 돌출핀(31)을 타고 넘어 돌출핀(31)에 걸리게 된다. However, when the door is rapidly descending at an abnormal speed, that is, the lifting wire rope or chain is broken when the door is opened and closed, the roller 41 of the pendulum 40 naturally rounds the round protrusion 50. Rather than going up and down, the pendulum 40 draws a large arc due to the force generated when the roller 41 hits the round protrusion 50 at an instant, so that the bent portion 431 of the elastic wire 43 is a protruding pin. (31) is instantaneously climbed, wherein the other end of the elastic wire (43), which is inserted into the roller rotation shaft hole (411) in a relaxed manner, by the elasticity, the original position of the roller rotation shaft hole (411) in the roller rotation shaft hole (411). While being pushed to another position at the bent portion 431 is caught over the protruding pin 31 by riding the protruding pin 31.

이와 같이 돌출핀(31)에 걸림과 동시에 걸림돌기(42)는 걸림구멍(60)에 삽입된 채 빠져나오지 못하기 때문에 슬라이더(30)가 급속강하하면서 걸림구멍(60)의 하단에 걸림돌기(42)의 하단이 걸쳐지게 된다. 이에 따라 급속강하하던 도어는 확실하게 강하를 멈추게 된다. In this way, the locking projection 42 is caught at the same time as the locking pins 60 are inserted into the locking holes 60, and thus the locking protrusions 42 are rapidly lowered while the slider 30 is rapidly lowered. 42, the lower end will be spread over. As a result, the door that has descended rapidly stops descending.

이후, 도어의 수리를 위해서 도어를 위로 밀어올리면 걸림돌기(42)의 하향경사진 상면(421)이 걸림구멍(60)의 상단에 걸려 올라가면서 진자추(40)를 역방향, 즉 도면상 왼쪽방향으로 밀어버리는 힘에 의해 돌출핀(31)에 걸려있던 탄성와이어(43)의 절곡부(431)가 돌출핀(31)을 역방향으로 올라타고 넘으면서 걸림구멍(60) 에 삽입되어 있던 걸림돌기(42)가 빠져나오게 된다. Subsequently, when the door is pushed upward for repair of the door, the downwardly inclined top surface 421 of the locking protrusion 42 is caught up to the upper end of the locking hole 60 and the pendulum weight 40 is reversed, that is, leftward in the drawing. The locking projection 42 inserted in the locking hole 60 while the bent portion 431 of the elastic wire 43, which is caught on the protruding pin 31, rises in the opposite direction and moves over the protruding pin 31 by the force pushed out. ) Comes out.

이처럼 본 발명의 작동구조는 도어가 정상속도로 정속 승강시에는 슬라이더(30)에 설치되어 있는 진자추(40)가 급강하 방지 스토퍼인 라운드형 돌기(50)를 타고 올라가면서 걸림구멍(60)에 삽입되었다가 타고 내려오면서 걸림구멍(60)에서 빠져나오는 작은 원호를 그리다가 승강용 로프나 체인이 끊어져 비정상적인 속도로 급속강하시에는 순간적으로 라운드형 돌기(50)에 부딪히면서 생기는 힘에 의해 근 원호를 그리기 때문에 돌출핀(31)을 타고 넘게 되고 걸림돌기(42)는 걸림구멍(60)에 삽입되어 결국 도어의 급속강하가 멈추게 되는 복잡하지 않고 단순한 작동구조로 이루어져 있다. As described above, the operation structure of the present invention allows the pendulum 40, which is installed on the slider 30 at the constant speed ascending and climbing at the normal speed, to the engaging hole 60 while climbing up the round protrusion 50, which is a drop prevention stopper. After inserting and riding down, draw a small arc coming out of the locking hole (60), and when the lifting rope or chain is broken and rapidly descends at an abnormal speed, the circular arc (50) is instantaneously hit by the force generated by the round protrusion (50). Because of the drawing, the protruding pin 31 is passed over, and the locking protrusion 42 is inserted into the locking hole 60 and is composed of an uncomplicated and simple operation structure in which the rapid drop of the door is stopped.
