이와 같이, 본 발명의 오토락 문고리 래치(100)에 의해 문(1)을 폐쇄하고 개방하는 과정을 도 5 및 도 6을 참조하여 설명하면 다음과 같다.As described above, a process of closing and opening the door 1 by the auto lock door latch 100 according to the present invention will be described with reference to FIGS. 5 and 6.
먼저, 도 5를 참조하여, 문(1)을 폐쇄하는 경우를 설명하면, 문(1)을 닫아 결속부(110)의 걸림부재(112)가 문틀(3)의 모서리를 거쳐 문틀에 함몰 설치된 캐치(4) 내부로 이동될 때 후진했다가 횡방향 탄성부재(S1)의 복원력에 의해 전진하게 된다.First, referring to FIG. 5, a case in which the door 1 is closed will be described. The door 1 is closed and the locking member 112 of the binding unit 110 is recessed in the door frame through the edge of the door frame 3. When it is moved into the catch 4, it retreats and advances by the restoring force of the lateral elastic member S1.
이때, 결속부(110)의 돌기(114)가 후진하면서 잠금력 생성해제부(130)의 제1 레버(132) 하부에 형성된 가압부재(132a)를 뒤로 밀게 되며, 이 과정에서 제1 레버(132)의 상단에 형성된 제1 상측 수평부재의 단부가 제2 레버(134)의 상단에 형성된 제2 상측 수평부재의 단부를 밀게 된다.At this time, while the protrusion 114 of the binding unit 110 is reversed, the pressing member 132a formed at the lower portion of the first lever 132 of the locking force generating release unit 130 is pushed backward, and in this process, the first lever ( An end of the first upper horizontal member formed at the upper end of the 132 pushes the end of the second upper horizontal member formed at the upper end of the second lever 134.
즉, 제1 레버(132)가 결속부(110)의 돌기(114)에 의해 반시계 방향으로 회전되면 제1 상측 수평부재의 단부가 제2 상측 수평부재의 단부를 밀어 제2 레버(134)를 시계 방향으로 회전시키게 된다.That is, when the first lever 132 is rotated counterclockwise by the protrusion 114 of the binding unit 110, the end of the first upper horizontal member pushes the end of the second upper horizontal member and the second lever 134. Rotate clockwise.
다음으로, 제2 레버(134)가 시계 방향으로 회전되면서 잠금부(120)의 걸림돌기(124)를 간섭하고 있던 제2 수직부재의 걸림턱(134a)이 걸림돌기(124)에서 분리된다.Next, while the second lever 134 is rotated in the clockwise direction, the locking step 134a of the second vertical member which is interfering with the locking protrusion 124 of the locking part 120 is separated from the locking protrusion 124.
다음으로, 잠금부(120)는 종방향 탄성부재(S2)의 복원력에 의해 하강되어 잠금돌기(122)의 저면이 단차면(111) 상면에 위치된다.Next, the locking portion 120 is lowered by the restoring force of the longitudinal elastic member S2 so that the bottom surface of the locking protrusion 122 is positioned on the stepped surface 111.
다음으로, 결속부(110)가 횡방향 탄성부재(S1)의 복원력에 의해 전진되며, 결속부(110)의 전진 과정에서 단차면(111)에 형성된 안내 경사면(118)의 시작 부위에 잠금돌기(122)의 모서리가 위치되면 종방향 탄성부재(S2)의 탄성력에 의해 안내 경사면(118)을 따라 점차 하강하기 시작하여 결속홈(116)과 잠금부(120)의 잠금돌기(122)가 동일수직선상 위치되는 시점에서 잠금돌기(122)가 결속홈(116) 내에 위치된다.Next, the binding unit 110 is advanced by the restoring force of the transverse elastic member (S1), the locking projection at the start of the guide inclined surface 118 formed on the step surface 111 in the advancing process of the binding unit (110). When the corner of the 122 is positioned, it gradually begins to descend along the guide inclined surface 118 by the elastic force of the longitudinal elastic member S2, so that the locking protrusion 122 of the binding groove 116 and the locking part 120 are the same. The locking protrusion 122 is located in the binding groove 116 at the time when the vertical line is positioned.
이렇게, 결속부(110)의 결속홈(116)에 잠금부(120)의 잠금돌기(122)가 위치되어 결속부(110)가 이동되지 못하게 되므로 문(1)이 폐쇄된 상태를 유지하게 된다.As such, the locking protrusion 122 of the locking unit 120 is positioned in the binding groove 116 of the binding unit 110 so that the binding unit 110 is not moved, thereby keeping the door 1 closed. .

The secondary moving member 140 is reversed.
다음으로, 손잡이(2)를 회전시켜 잠금부 이동부재(140)의 경사면(142)이 점차 잠금부(120)의 걸림돌기(124)를 상방향으로 밀게 된다. 이때, 종방향 탄성부재(S2)는 압축된다.Next, by rotating the handle 2, the inclined surface 142 of the locking unit moving member 140 gradually pushes the locking projection 124 of the locking unit 120 in the upward direction. At this time, the longitudinal elastic member S2 is compressed.
다음으로, 잠금부 이동부재(140)의 경사면(142)에 의해 잠금부(120)의 걸림돌기(124)가 상방향으로 이동되면서 제2 레버(134)의 제2 수직부재에 형성된 걸림턱(134a)의 경사면을 점차 밀어 제2 레버(134)를 시계 방향을 회전시킨다.Next, the locking projections 124 of the locking portion 120 are moved upward by the inclined surface 142 of the locking portion moving member 140 and the locking jaw formed on the second vertical member of the second lever 134 ( The inclined surface of 134a is gradually pushed to rotate the second lever 134 clockwise.
다음으로, 제2 레버(134)가 시계 방향을 회전되면서 걸림돌기(124)의 정점 부위가 걸림턱(134a)의 모서리를 통과하면 걸림돌기(124)가 걸림턱(134a) 상에 걸리게 된다.Next, when the second lever 134 is rotated in the clockwise direction when the apex portion of the locking projection 124 passes through the edge of the locking projection 134a, the locking projection 124 is caught on the locking projection 134a.
이렇게, 잠금부(120)는 걸림돌기(124)가 제2 레버(134)의 걸림턱(134a)에 걸리면서 종방향 탄성부재(S2)의 탄성력이 가해진 상태로 위치가 고정된다.In this way, the locking portion 120 is fixed to a position in which the locking projection 124 is caught in the locking step 134a of the second lever 134 while the elastic force of the longitudinal elastic member S2 is applied.
