도 1은 본 발명의 잠금장치의 제1실시예의 사시도이고, 도 2는 도 1의 A-A'선의 단면도이고, 도 3은 도 1의 B-B'선의 단면도이고, 도 4는 본 발명의 잠금장치의 제1실시예가 가이드 레일에 설치된 상태에서 밀림방지수단이 록킹되는 과정을 설명하는 사시도이다.1 is a perspective view of a first embodiment of the locking device of the present invention, FIG. 2 is a sectional view taken along the line A-A 'of FIG. 1, FIG. 3 is a sectional view taken along the line B-B' of FIG. A first embodiment of the locking device is a perspective view illustrating a process of locking the rolling prevention means in a state installed on the guide rail.

잠금장치(1)는 밀림방지장치(50)의 돌출편(51)이 삽입됨에 따라서 상승되는 작동편(10)과 작동편(10)의 상하 유동되는 폭을 제한하며, 작동편(10)이 가이드 레일(2)로부터 이탈되지 않도록 하는 하우징(20)으로 이루어진다. The locking device 1 limits the width of the moving piece 10 and the moving piece 10 that are moved up and down as the protruding piece 51 of the slide preventing device 50 is inserted, and the operating piece 10 is It consists of a housing 20 to prevent it from being separated from the guide rail 2.

작동편(10)은 가이드 레일(2)의 요홈(3)길이방향으로 설치되는 이탈 방지판(11)과 이탈 방지판(11)의 중심에 하향 설치되는 몸체(12)와, 몸체(12)의 저면에는 나사(14)에 의하여 걸림부(13)가 결합된다. 이때, 몸체(12)는 사각형상으로 형성되며, 걸림부(13)는 판상부재로 몸체(12)의 단면적보다 크게 형성된다.The operation piece 10 includes a body 12 installed downward in the center of the separation prevention plate 11 and the separation prevention plate 11 installed in the length direction of the groove 3 of the guide rail 2, and the body 12. On the bottom of the engaging portion 13 is coupled by a screw (14). At this time, the body 12 is formed in a rectangular shape, the locking portion 13 is formed in a plate-like member larger than the cross-sectional area of the body 12.

또한, 하우징(20)은 도어 실을 형성하는 가이드 레일(2)의 길이방향으로 형성된 요홈(3) 내부에 가이드 레일(2)의 외면으로부터 요홈(3)을 횡단하는 나사(4), (5)에 의하여 결합된다.In addition, the housing 20 is a screw (4), (5) crossing the groove (3) from the outer surface of the guide rail (2) inside the groove (3) formed in the longitudinal direction of the guide rail (2) forming the door seal (5) ) Are combined.

하우징(20)의 내부에는 걸림부(13)가 상하 이동될 수 있도록 공간이 형성되는 수용부가 형성되며, 외면 형상은 반원 형상으로 이루어지는 양 측면(24), (25)과 양 측면(24), (25)을 연결하는 연결면(26)으로 이루어지며, 연결면(26)의 정점에는 4각형상의 관통구(23)가 형성되어 관통구(23)는 수용부가 형성하는 내부 공간과 통공되지만 관통구(23)의 면적은 걸림부(13)의 면적보다 작게 형성함으로써 관통구와 수용부의 연결부위에는 단턱(27), (28)이 형성되어 단턱(27), (28)에 걸림부(13)가 걸려 몸체(12)의 상승 높이가 제한된다.An interior of the housing 20 is provided with a receiving portion in which a space is formed so that the locking portion 13 can be moved up and down, and the outer surface has both side surfaces 24 and 25 and both side surfaces 24 having a semicircular shape. Comprising a connecting surface 26 for connecting the 25, the top of the connecting surface 26 is formed with a quadruple through-hole 23, the through-hole 23 is through the inner space formed by the receiving portion but through Since the area of the sphere 23 is smaller than the area of the engaging portion 13, the stepped portions 27 and 28 are formed at the connecting portion of the through hole and the receiving portion, so that the engaging portions 13 are formed at the stepped portions 27 and 28. The rising height of the body 12 is restricted.

또한, 가이드 레일(2)의 요홈을 형성하는 외측벽(6)에는 관통공(41), (42)이 형성되며, 내측벽(7)에는 나사산이 형성된 나사공(43), (44)이 형성되며, 하우징(20)에는 나사(4), (5)가 관통하는 관통공(21), (22)이 형성된다.In addition, through-holes 41 and 42 are formed in the outer wall 6 forming the groove of the guide rail 2, and screw holes 43 and 44 in which the thread is formed in the inner wall 7 are formed. The housing 20 is formed with through holes 21 and 22 through which the screws 4 and 5 penetrate.

도 1에 도시된 실시예의 잠금장치(1)를 가이드 레일에 설치하기 위해서는 우 선 하우징의 연결면(26)에 형성된 관통구(23)에 상부에 이탈방지판(11)이 설치된 몸체(12)를 삽입시킨 후 몸체(12)의 저면 단부에 걸림부(13)를 나사(14)로 결합시킨다. 이와 같이 작동편(10)이 결합된 하우징(20)을 관통구(23)가 상향되도록 가이드 레일(2)의 요홈(3)에 안착시키고, 나사(4), (5)에 의하여 가이드 레일(2)과 하우징(20)을 결합시킨다.In order to install the locking device 1 of the embodiment shown in FIG. 1 to the guide rail, the body 12 is provided with a separation prevention plate 11 at the upper portion of the through hole 23 formed in the connection surface 26 of the housing. After inserting the engaging portion 13 to the bottom end of the body 12 is coupled to the screw (14). In this way, the housing 20 to which the operation piece 10 is coupled is seated in the groove 3 of the guide rail 2 so that the through hole 23 is upward, and the guide rail (5) by the screws 4 and 5. 2) and the housing 20 are combined.

가이드 레일(2)에 하우징(20)을 나사(4), (5)로 결합시키기 위하여 가이드 레일(2)의 측벽(6), (7)에 하우징(20)에 형성된 관통공(21), (22)들이 이격된 폭만큼 관통공 또는 나사공을 형성한 후 하우징(20)을 안착시킨 후 나사(4), (5)를 조립함으로써 간단히 잠금장치(1)를 설치할 수 있기 때문에 시공이 매우 편리하다.Through holes 21 formed in the housing 20 on the sidewalls 6, 7 of the guide rail 2 to couple the housing 20 to the guide rail 2 with screws 4, 5, The construction is very easy because the locking device 1 can be simply installed by assembling the screws 4 and 5 after mounting the housing 20 after forming the through holes or the screw holes by the widths of the 22 parts. It is convenient.

이와 같이, 가이드 레일(2)에 잠금장치(1)가 설치되고, 도어에 설치된 밀림방지장치(50)의 돌출편(51)은 도어의 패쇄시에 잠금장치(1)의 이탈방지판(11)의 하부 공간에 삽입되게 되고, 밀림방지장치(50)로부터 이탈방지판(11)을 상승시키는 외력이 가해지는 경우에 이탈방지판(11)은 상승되지만 걸림부(13)에 의하여 상승폭이 제한되게 되고, 결국 밀림방지장치(50)의 돌출편은 이탈방지판(11)과 요홈이 형성하는 공간에 록킹되게 된다.In this way, the locking device 1 is installed on the guide rail 2, and the protruding pieces 51 of the rolling prevention device 50 provided on the door are separated from the lock plate 11 of the locking device 1 when the door is closed. When the external force is raised in the lower space of the), and when the external force that lifts the departure prevention plate 11 from the rolling prevention device 50 is applied, the departure prevention plate 11 is raised but the rising width is limited by the locking portion 13 As a result, the protruding pieces of the anti-rolling device 50 are locked in the space formed by the release preventing plate 11 and the groove.

이탈방지판(11)의 길이방향의 단부의 하면은 밀림방지장치(50)가 삽입될 때 마찰없이 삽입될 수 있도록 경사면이 형성된다.The lower surface of the end portion in the longitudinal direction of the release preventing plate 11 is formed with an inclined surface to be inserted without friction when the anti-rolling device 50 is inserted.

또한, 도 1 내지 4의 실시예에서 하우징의 형상을 이물질이 축적되지 않도록 반원형상으로 구성하였으나, 이에 국한되지 않고, 일정한 경사각을 갖는 경사면 또는 수직면으로 형성할 수 있다.In addition, in the embodiment of Figures 1 to 4, the shape of the housing is configured in a semi-circular shape so that foreign matter does not accumulate, but is not limited thereto, and may be formed as an inclined surface or a vertical surface having a predetermined inclination angle.

상기의 목적과 구성을 갖는 본 발명에 따르면, 잠금장치(1)를 도어 실을 형성하는 가이드 레일의 요홈에 매우 편리하게 시공할 수 있기 때문에 설치시에 발생되는 불량시공을 감소시킬 수 있으며, 인건비를 절약할 수 있다.According to the present invention having the above object and configuration, since the locking device 1 can be installed very conveniently in the groove of the guide rail forming the door seal, the poor construction occurring at the time of installation can be reduced, and the labor cost Can save.

또한, 잠금장치(1)의 이탈방지판(11)이 상하 이동 가능하므로 도어의 하부에 설치된 밀림방지장치의 돌출편(51)의 설치 높이가 도어마다 다르다고 하여도 동일한 잠금장치를 사용할 수 있으므로 특정 도어에 국한되지 않는 범용성을 갖는 잠금장치를 구현할 수 있다.In addition, since the release preventing plate 11 of the locking device 1 can be moved up and down, the same locking device can be used even if the height of the protrusion 51 of the anti-rolling device installed on the lower part of the door is different for each door. It is possible to implement a locking device having a versatility not limited to the door.
