One protruding portion of the key 63 protrudes more than the other protruding portion. That is, one side of the key 63 is formed to protrude to the outside of the housing 20 , and when the door 75 is closed, the key 63 is caught inside the latch 70 to maintain a locked state. Here, the latch 70 is provided in the main body 71 of the mechanism, and as a door 75 switch, when the door 75 is closed, the latch 70 performs a switch operation to recognize the closed state of the door 75 . The key 63 may be caught by the latch 70 to maintain the locked state of the door 75 . The other side of the key 63 is rotated along the convex portion 21 of the housing 20 and the groove 51 of the main rod 50 as described above.
직선 걸이부(65)는 중심부(61)에서 키(63)의 일측 방향으로 나란하게 형성되고 메인 로드(50)의 돌출부(53)와 맞닿도록 형성된다. 직선 걸이부(65)는 제1 직선 걸이부(65a)와 제2 직선 걸이부(65b)를 포함하고, 제1 및 제2 직선 걸이부(65a, 65b) 사이에 메인 로드(50)가 구비된다.The straight hook 65 is formed to be parallel to one side of the key 63 in the central portion 61 and to come into contact with the protrusion 53 of the main rod 50 . The straight hook part 65 includes a first straight hook part 65a and a second straight hook part 65b, and the main rod 50 is provided between the first and second straight hook parts 65a and 65b. do.
곡선 걸이부(67)는 중심부(61)에서 아치 형태로 굴곡져서 직선 걸이부(65)와 나란하게 구비되고, 메인 로드(50)의 돌출부(53)와 맞닿도록 형성된다. 곡선 걸이부(67)는 제1 곡선 걸이부(67a)와 제2 곡선 걸이부(67b)를 포함하고, 제1 및 제2 곡선 걸이부(67a, 67b) 사이에 메인 로드(50)가 구비된다.The curved hook 67 is bent in an arcuate shape from the center 61 to be provided in parallel with the straight hook 65 and is formed to abut against the protrusion 53 of the main rod 50 . The curved hook portion 67 includes a first curved hook portion 67a and a second curved hook portion 67b, and a main rod 50 is provided between the first and second curved hook portions 67a and 67b. do.
즉, 도 4c와 도 4d에 도시된 바와 같이, 각 직선 걸이부(65)와 각 곡선 걸이부(67) 사이에는 메인 로드(50)가 구비되고, 직선 걸이부(65)와 곡선 걸이부(67) 사이에는 메인 로드(50)의 돌출부(53)가 구비된다. 도 4c는 도어(75)의 닫힘 상태이고, 도 4d는 도어(75)의 열림 상태이다. 도 4c와 같은 상태에서 도어(75)의 회동 시, 메인 로드(50)의 직선 이동으로 인해, 돌출부(53)가 직선 걸이부(65)와 곡선 걸이부(67)와 마찰되어 도 4d와 같이 키 도어(60)를 회동시킨다.That is, as shown in FIGS. 4C and 4D, a main rod 50 is provided between each straight hooking part 65 and each curved hooking part 67, and the straight hooking part 65 and the curved hooking part ( A protrusion 53 of the main rod 50 is provided between the 67 . FIG. 4C is a closed state of the door 75 , and FIG. 4D is an open state of the door 75 . When the door 75 is rotated in the state as shown in FIG. 4c, due to the linear movement of the main rod 50, the protrusion 53 rubs against the straight hook 65 and the curved hook 67, as shown in FIG. 4d. The key door 60 is rotated.
도어(75)의 닫힘 상태에서 키 도어(60)의 키(63)는 메인 로드(50)와 직각 상태를 유지하며 돌출되어 있다. 이로 인해, 전술한 바와 같이, 키(63)는 래치(70)에 걸려 도어(75)의 잠금 상태를 유지할 수 있다. 도어(75)의 열림 상태에서 키 도어(60)의 키(63)는 키 도어(60)의 회동으로 인해 하우징(20) 쪽으로 이동된다. 즉, 키(63)가 회동되어메인 로드(50)와 나란하게 된다. 이와 같이, 키 도어(60)가 외관상 돌출되지 않으므로, 키 도어(60)의 파손 등이 방지될 수 있다.In the closed state of the door 75 , the key 63 of the key door 60 protrudes while maintaining a perpendicular state with the main rod 50 . Accordingly, as described above, the key 63 may be caught by the latch 70 to maintain the locked state of the door 75 . In the open state of the door 75 , the key 63 of the key door 60 is moved toward the housing 20 due to the rotation of the key door 60 . That is, the key 63 is rotated to be parallel to the main rod 50 . As described above, since the key door 60 does not protrude from the outside, damage to the key door 60 can be prevented.
다음으로, 본 실시예에 따른 풀 다운 도어용 힌지(100)의 동작 상태에 대하여 살펴본다. 도 5는 도어의 닫힘 상태에서 열림 상태에 따른 본 발명에 따른 풀 다운 도어용 힌지의 동작 상태를 나타낸 도면이다.Next, an operation state of the hinge 100 for a pull-down door according to the present embodiment will be described. 5 is a view showing the operating state of the hinge for a pull-down door according to the present invention according to the open state from the closed state of the door.
먼저, 도어(75)의 닫힘 시, 풀 다운 도어용 힌지(100)는 도 5와 같이 세로로 세워져 있는 상태이다. 이 때, 탄성부재(40)는 인장되어 있는 상태이고, 키 도어(60)는 돌출되어 래치에 걸려 잠금을 유지하고 있다.First, when the door 75 is closed, the hinge 100 for the pull-down door is in a vertically standing state as shown in FIG. 5 . At this time, the elastic member 40 is in a tensioned state, and the key door 60 protrudes and is caught by the latch to maintain the lock.
이어서, 도어를 회동시키면, 탄성부재(40)는 점점 수축되고, 키 도어(60)도 하우징 쪽으로 점점 회동된다. 이 때, 링크부(30)가 본체 프레임(10) 쪽으로 직선 이동되고, 링크부(30)와 연결된 메인 로드(50)가 직선 이동된다. 따라서, 탄성부재(40)가 점섬 수축되고, 키 도어(60)도 점점 회동된다.Then, when the door is rotated, the elastic member 40 is gradually contracted, and the key door 60 is also gradually rotated toward the housing. At this time, the link part 30 is linearly moved toward the body frame 10 , and the main rod 50 connected to the link part 30 is linearly moved. Accordingly, the elastic member 40 is gradually contracted, and the key door 60 is also gradually rotated.
다음으로, 도어를 완전히 오픈시키면, 탄성부재(40)는 링크부(30)와 메인 로드(50) 사이에서 수축되고, 키 도어(60)는 하우징 쪽으로 회동되어 메인 로드(50)와 나란하게 된다. 링크부(30)와 메인 로드(50)가 본체 프레임(10) 쪽으로 직선 이동되어, 탄성부재(40)가 수축되며, 키 도어(60)가 회동된다.Next, when the door is completely opened, the elastic member 40 is contracted between the link part 30 and the main rod 50 , and the key door 60 is rotated toward the housing to be parallel with the main rod 50 . . The link part 30 and the main rod 50 are linearly moved toward the body frame 10 , the elastic member 40 is contracted, and the key door 60 is rotated.
