Description

지렛대의 원리를 이용한 문 잠금 장치{DOOR LOCK SYSTEM USING LEVER PRINCIPLE}Door lock system using the lever principle{DOOR LOCK SYSTEM USING LEVER PRINCIPLE}

본 발명은 여닫이문 잠금 장치에 관한 것으로, 보다 상세하게는 현관문 등 출입구 개폐용 여닫이문의 잠금장치의 잠금 또는 잠금해제 동작을 지렛대의 원리를 이용한 극대화된 사람의 힘으로 할 수 있게 하여 더욱 안전성을 얻을 수 있는 잠금장치에 관한 것이다.The present invention relates to a swing door locking device, and more specifically, to make the locking or unlocking operation of the locking device of the swing door for opening and closing a doorway, etc. to be maximized by using the principle of a lever, thereby increasing safety. It relates to a lock that can be obtained.

도 1은 종래잠금장치(100)에 관한 것으로써 통상적으로 보아오던 일반가정집의 현관문에 설치되어 있는 잠금장치이다. 이는 문틀에 종래걸림장치(110)가 볼트결합으로 고정되어 있으며 상기 종래걸림장치(110)의 일측에는 걸림돌기(111)가 좌우가 전환된 'C'형상으로 이루어져 있다.1 relates to a conventional locking device 100, and is a locking device installed on the front door of a general home that has been commonly seen. This is a conventional hooking device 110 is fixed to the door frame in a bolted connection, and the side of the conventional hooking device 110 is made of a'C' shape in which the locking protrusion 111 is switched left and right.

또한 여닫이 문에 설치되는 종래고정장치(120)에 힌지결합하는 회절바아(121)는 그 단면이 H형상으로 이루어지고 상기 회절바아(121)의 상부 및 하부로 형성되어 있는 걸림턱(122)중 일부가 제거되어 문이 닫혀있는 상태에서 힌지결합부분에서 회절운동이 생겨 상기 걸림돌기(111)가 회절바아(121)의 내부로 삽입되는 구조로 형성되어있다.In addition, the diffraction bar 121 hingedly coupled to the conventional fixing device 120 installed in the casement door has an H-shape in cross section and is formed among the locking jaws 122 formed at the top and bottom of the diffraction bar 121. Diffraction motion is generated at the hinge-coupled part in a state where the door is closed due to the removal of the part, so that the locking protrusion 111 is formed into a structure that is inserted into the diffraction bar 121.

그러나 이러한 종래잠금장치(100)는 위험성이 내재되어 있는 것으로써, 외부인이 문이 벌어진 약간의 간격을 이용하여 끈으로써 회절바아(121)를 움직여 문을 열거나, 외부인이 힘으로 파괴하는 경우가 있어 외부에서 침입을 시도하는 등의 위험 상황에 잠금 상태를 유지 할 수 없을 가능성이 존재하는 문제점이 있다.However, such a conventional locking device 100 is inherently dangerous, and the outsider moves the diffraction bar 121 to open the door by turning it off using a slight gap between the doors, or when an outsider destroys it with force. There is a problem that there is a possibility that the locked state cannot be maintained in a dangerous situation such as an attempt to invade from the outside.
