Description

현관문용 안전고리{Locking device for opening and closing type door}Safety hook for front door {Locking device for opening and closing type door}

본 고안은 현관문용 안전고리에 관한 것으로, 더욱 상세하게는 여닫이식 현관문을 닫은 상태에서 문을 열 수 없도록 고정시킬 수 있게 함으로서, 안전성을 더욱 극대화시킨 것이다.The present invention relates to a safety hook for a front door, and more specifically, by enabling the door to be fixed so that the door cannot be opened in the closed state, the safety is further maximized.

일반적으로 가정집의 현관문에는 방범상태를 유지한 채 외부인을 확인하거나 또는 공기를 소통시키기 위해 약간만 열어 놓고 고정시킬 수 있도록 안전고리가 설치된다.In general, a safety ring is installed on the front door of a house so that it can be fixed by opening it slightly in order to check outsiders or to communicate air while maintaining a crime prevention state.

도1은 종래 현관문용 안전고리를 나타낸 도면이다.1 is a view showing a safety ring for a conventional front door.

도1에 도시된 바와 같이, 종래 현관문용 안전고리는 문틀에 부착되는 걸림브래킷(3)과, 문에 힌지 결합되며 상기 걸림브래킷(3)과 걸어 고정되며 일정한 개방구간을 제공하는 걸림바(2)로 구성된다.As shown in Figure 1, the conventional safety hook for the front door is a locking bracket (3) attached to the door frame, a locking bar (2) that is hinged to the door, is hooked and fixed with the locking bracket (3), and provides a constant opening section. ) is composed of

걸림브래킷(3)은 문틀에 부착되며 상하부 지지편(31)(31') 내측 면에 안내돌부(32)가 형성된다. 상기 안내돌부(32)는 상하부에 대향되게 형성된다.The locking bracket 3 is attached to the door frame, and guide protrusions 32 are formed on the inner surfaces of the upper and lower support pieces 31 and 31 ′. The guide protrusion 32 is formed to face the upper and lower portions.

걸림바(2)는 문에 부착되는 힌지브래킷(1)에 결합되어 회전되며 일정 길이로 형성되고 상기 안내돌부(32)가 삽입되도록 일정 길이의 작동홈(23)이 형성되고 일측에 개방부(23a)가 형성된다.The locking bar (2) is rotated by being coupled to the hinge bracket (1) attached to the door, is formed to a certain length, and an operation groove (23) of a certain length is formed so that the guide protrusion (32) is inserted, and an open part ( 23a) is formed.

즉, 상기 걸림바(2)는 단면이 'H' 형상이며, 상, 하부에 동일한 길이와 깊이를 갖는 작동홈(23)이 형성되고, 상기 힌지브래킷(1)과 인접된 부위가 절개되어 상기 안내돌부(32)가 삽입될 수 있도록 개방부(23a)가 형성된다.That is, the locking bar 2 has an 'H' shape in cross section, and operating grooves 23 having the same length and depth are formed on the upper and lower sides, and the portion adjacent to the hinge bracket 1 is cut out. An opening (23a) is formed so that the guide protrusion (32) can be inserted.

이러한 종래 현관문용 안전고리는 외부인의 방문시 안전을 위하여 안내돌부(32)가 걸림바(2)에 삽입된 상태로 문을 열게되는 경우 안내돌부(32)가 걸림바(2)의 말단까지 이동됨으로써 외부의 안전을 확인하고 다시 문을 닫은 후 걸림바(2)를 회전시켜 안내돌부(32)의 삽입상태를 해지 후 문을 열게 된다.In this conventional safety ring for the front door, when the door is opened with the guide protrusion 32 inserted into the locking bar 2 for safety when an outsider visits, the guide protrusion 32 moves to the end of the locking bar 2 As a result, after confirming the safety of the outside and closing the door again, the locking bar (2) is rotated to release the insertion state of the guide protrusion (32), and then the door is opened.

그러나 상기한 종래 현관문용 안전고리는 단순히 외부인을 확인하거나, 환기를 위해 약간 열어놓는 정도의 용도로는 사용가능하지만 외부에서 침입을 위해 현관정을 개방할 때는 안전고리는 안전장치로서의 기능을 제대로 수행할 수 없게 된다.However, the conventional safety ring for the front door can be used for the purpose of simply checking outsiders or opening the door slightly for ventilation, but when the door is opened for intrusion from the outside, the safety ring can function as a safety device properly. becomes impossible

다시 말하면, 상기한 종래의 안전고리는 방문객의 확인이나 환기용도로는 사용가능하므로 실내에서 안전고리를 걸어놓은 상태에서 현관정을 잠가놓더라도 외부에서 침입자가 현관정을 개방하게 되면 안전고리에 의해 완전개방은 되지 않더라도 일부가 개방될 수밖에 없어 개방된 부분을 통해 절단기 등으로 안전고리를 절단할 수 있게 되어 안전성이 떨어진다는 것이다.In other words, since the above-mentioned conventional safety ring can be used for visitor confirmation or ventilation purposes, even if the door is locked while the safety ring is hung indoors, if an intruder opens the door from the outside, the door is completely opened by the safety ring. Even if it does not work, some parts are inevitably opened, and the safety ring can be cut with a cutter or the like through the open part, which lowers safety.

본 고안은 전술한 종래 현관문용 안전고리에 대한 제반문제점을 해결하기 위해 안출된 것으로, 특히 안전고리로서의 작용뿐 아니라 잠금장치로서의 작용도 수행할 수 있게 함으로서 안전성을 더한층 높일 수 있게 하는 현관문용 안전고리를 제공하려는데 그 목적이 있는 것이다.The present invention has been devised to solve all the problems with the conventional safety hook for the front door described above, and in particular, the safety ring for the front door that can further enhance safety by enabling it to perform not only as a safety ring but also as a locking device It is intended to provide

한편, 상기 잠금핀(4)의 헤드(41)를 눌러 오뚜기핀(5)이 상부 걸림홈(42b)에 걸리게 하는 경우는 잠금봉(42a)이 잠금공(22a)에 삽입되어 침입하기 위해 외부에서 도어록을 인위적으로 열더라도 잠금공(22a)에 잠금봉(42a)의 하부가 끼워져 있으므로 도어가 열리지 않게 되므로서 안전한 잠금장치로서의 기능을 하게 되는 것이다.On the other hand, when the Ottogi pin 5 is caught in the upper locking groove 42b by pressing the head 41 of the locking pin 4, the locking rod 42a is inserted into the locking hole 22a. Even when the door lock is artificially opened in the , the door does not open because the lower part of the lock rod 42a is inserted into the lock hole 22a, thereby functioning as a safe locking device.

또 잠금장치를 해정하고자 할 때는 헤드(41)를 잡아당겨 오뚜기핀(5)에 하부 걸림홈(42b)이 걸리게 하면 잠금공(22a) 속에 삽입되어 있던 잠금봉(42a)이 상승하여 잠금공(22a)에서 벗어나 위치하게 되므로 안내돌부로서의 작용을 할 수 있게 된다.Also, when you want to unlock the locking device, if you pull the head 41 so that the lower locking groove 42b is caught on the Ottogi pin 5, the locking rod 42a inserted in the locking hole 22a rises and the locking hole ( 22a), so it can act as a guide protrusion.

따라서 걸림바(2)를 걸림브래킷(3)의 상하부 지지편(31)(31') 사이에 끼워 넣고 문을 닫은 상태에서 잠금핀(4)의 헤드를 누르거나 잡아 빼는 단순한 동작에 의해 도어 잠금장치로도 사용할 수 있고, 또 안전고리로도 사용할 수 있어 다목적 사용이 가능한 것이다.Therefore, the locking bar 2 is inserted between the upper and lower support pieces 31 and 31' of the locking bracket 3 and the door is locked by a simple operation of pressing or pulling the head of the locking pin 4 in the closed state. It can be used as a device and also as a safety ring, so it can be used for multiple purposes.
