도어록 보호용 커버{COVER FOR PROTECTIVE IN DOOR LOCK}Door lock protective cover {COVER FOR PROTECTIVE IN DOOR LOCK}

본 발명은 방화문을 포함한 출입문의 실내면과 실외면의 사이에 설치되는 도어록에서 실외면에 위치하는 외부 도어록을 무단침입자나 빗물 등으로부터 보호하기 위하여 출입문의 실외면과 도어록 홈 사이에 본체와 전방 커버부로 이루어진 보호용 커버를 장착한 후, 도어록을 보호용 커버로 밀폐한 다음 도어를 열고 닫을 때 전방에 위치한 전면 커버부의 회동으로 커버를 개폐한 후 도어록을 사용함으로 인해 야간에는 도어록의 파손에 의한 도난을 방지하고, 외부의 도어록에 형성된 열쇠구멍으로는 눈과 빗물이 침투되어 부식되는 것을 방지할 수 있는 도어록 보호용 커버에 관한 것이다.
The present invention is a door lock installed between the interior and the outdoor surface of the door including a fire door to protect the outer door lock located on the outdoor surface from unauthorized intruders or rainwater, the main body and the front cover between the outdoor door and the door lock groove After attaching the protective cover made of parts, seal the door lock with the protective cover, and then open and close the cover by rotating the front cover part located at the front when opening and closing the door, and then use the door lock to prevent theft due to the damage of the door lock at night. In addition, the keyhole formed in the outer door lock relates to a door lock protective cover that can prevent the snow and rain water penetrates and corrodes.

일반적으로, 방화문(FIRE DOOR)은 건물 내부에서 화재가 발생되면, 화재가 더 넓은 공간으로 확산되는 것을 방지함은 물론, 확산된 화재에 의해 인명 및 재산 피해가 최소화되도록 하는 것으로, 셔터, 건물의 출입문, 현관문, 방문 등에 주로 이용되고 있다.In general, when a fire occurs inside a building, a fire door prevents the fire from spreading to a larger space, and minimizes the damage to life and property due to the spreading fire. It is mainly used for entrance doors, front doors and visits.

상기 방화문은 측면으로 래치가 삽입 설치된 상태에서 문틀에 형성된 걸림 구멍으로 래치 볼트가 래치에서 출몰하여 걸리거나 걸림을 해제하여 도어를 잠금 또는 잠금을 해제하는 구조로 이루어진다.The fire door is a locking hole formed in the door frame in the state that the latch is inserted into the side is made of a structure that locks or unlocks the door by latching or releasing the latch from the latch.

또한, 방화문이 닫혔을 때 자동으로 열리지 않게 닫힌 상태를 유지하고, 필요시에만 개방될 수 있도록 함과 동시에 마음대로 개폐되는 것을 방지하기 위하여 출입문의 실내외에는 래치와 연동되는 도어록이 장착된다.In addition, the door lock is interlocked with the latch inside and outside the door to maintain the closed state so as not to open automatically when the fire door is closed, to be opened only when necessary, and to prevent the door from opening and closing at will.

따라서 도어록을 일 방향으로 돌리면 래치 볼트가 연동하여 문틀에 형성된 걸림 구멍에서 삽입 및 인출되어 출입문을 열고 닫을 수 있도록 한다. Therefore, when the door lock is turned in one direction, the latch bolt is interlocked to insert and withdraw from the locking hole formed in the door frame to open and close the door.

그러나 방화문에서 설치된 도어록중 실외에 위치하는 도어록은 외부에 노출된 상태로 방치되는 경우가 많이 있어 눈 또는 비가 내리면 빗물 등이 열쇠 구멍으로 스며들어 쉽게 녹이 슬어버려 열쇠가 제대로 꽂아지지 않고 작동이 원활하지 않는 문제점이 있다.However, among the door locks installed in the fire doors, the door locks located outside are often exposed to the outside, and when snow or rain falls, rainwater penetrates into the keyholes and easily rusts, causing the keys not to be properly inserted and smoothly operated. There is a problem.

또한, 타인이 강제로 도어록을 파손한 다음 방화문을 열고 실내로 들어가는 경우가 종종 있는데 이런 경우에는 외부에 노출되어 있는 방화문과 실외면과 도어록의 밀착면 사이로 날카로운 도구를 삽입하여 틈새를 벌리거나 또는 도어록을 망치 등으로 타격하여 부숴버리고 방화문을 열고 들어간다.In addition, it is often the case that someone else forcibly breaks the door lock and then opens the fire door and enters the room.In this case, a gap between the exposed fire door and the outdoor surface and the close contact surface of the door lock is inserted to open the gap or the door lock. Smash it with a hammer and open the fire door.

이와 같은 이유는 방화문 또는 컨테이너의 출입문과 같이 실외에 장착된 도어록은 외부에 그대로 노출된 상태로 있기 때문에 주로 야간에 무단침입자가 마음만 먹으면 쉽게 부순 다음 방화문을 열고 실내로 침입할 수 있는 문제점이 있다.
The reason for this is that the door lock mounted outdoors, such as a fire door or a container door, is exposed to the outside as it is, so that if an intruder enters the room at night, it can easily break and then break into the room. .
