매립형 도어 힌지를 가지는 안전 방화문 문틀 구조{Security doors with flush door frame structure, door hinge}Security doors with flush door frame structure, door hinge

본 발명은 매립형 도어 힌지를 가지는 안전 방화문 문틀 구조에 관한 것으로, 더욱 상세하게는 방화문과 측면 문틀 사이를 밀폐시켜 단열, 방음, 결로 현상을 배제시키게 하는 것으로 특히, 사용자의 손가락이 방화문 개폐 시 방화문과 측면 문틀 사이에 끼어 안전사고를 유발하는 위험성을 배제시키는 것이다.The present invention relates to a safety fire door door frame structure having a buried door hinge, and more specifically, to seal a gap between a fire door and a side door frame to exclude insulation, sound insulation, and condensation, especially when a user's finger opens and closes the fire door It is to exclude the risk of causing safety accidents between the side door frames.

일반적으로, 방화문은 화재발생시 연기와 열기의 침입 또는 확산을 방지하는 역할을 수행한다. 특히 방화문은 아파트와 같은 공동주택의 현관이나 빌딩 사무실의 출입구 등에 설치되고 있다.In general, fire doors serve to prevent the intrusion or spread of smoke and heat in the event of a fire. In particular, fire doors are installed in the entrances of apartments such as apartments, and in the entrances of building offices.

한편, 방화문의 문틀은 화재에 강한 금속재질로 제작되며, 방화문의 어느 한쪽에 전달된 열기가 다른 쪽으로 전달되는 것을 최대한 차단할 수 있도록 내부에 방염부재가 채워질 수 있다.On the other hand, the door frame of the fire door is made of a metal material that is resistant to fire, and a flame retardant member may be filled in to prevent the heat transmitted to one side of the fire door from being transmitted to the other side as much as possible.

더구나, 방화문과 문틀 사이에 형성된 공간부를 고무패킹 등으로 밀폐시켜 단열, 결로현상 배제, 방음을 수행하는 기술들이 국내 등록특허 제10-1101935호 및 일본공개 특허 제2001-10766호 등에 게재되어 있다. 이러한 기술들은 측면 문틀에 형성된 요입부에 바깥측으로 날개편이 형성된 고무 밀폐 패킹을 삽입하여 고정시키는 구성으로 이루어져 있다.Moreover, techniques for insulating, condensation excluding, and soundproofing by sealing the space formed between the fire door and the door frame with rubber packing are published in Korean Patent Registration No. 10-1101935 and Japanese Patent Publication No. 2001-10766. These technologies consist of a configuration in which a rubber seal packing having a wing piece is inserted into and fixed to an inlet portion formed in a side door frame.

이와 같은 구성을 가지는 방화문은 닫거나 여는 경우 고무 밀폐 패킹의 날개편이 방화문의 일측단부와 문틀 사이에 형성된 공간부를 밀폐시키는 것이나, 상기 날개편이 얇은 편으로 되어 있어 유동성을 가지므로 공기나 열을 차단하는 효과는 있을지라도 방화문을 조작하는 사용자가 상기 방화문의 일측단부와 문틀 사이에 형성된 공간부에 손가락(또는 손)을 실수로 넣는 경우 손가락의 미는 힘에 의해 날개편이 내측으로 밀려지게 되어 방화문의 개폐 시 방화문 일단부에 손가락이 끼어져 손상을 입게 되는 안전사고 발생이 문제점으로 지적된다.When closing or opening a fire door having such a configuration, the wing piece of the rubber-sealed packing seals the space formed between one end of the fire door and the door frame, or because the wing piece is thin, it has fluidity, thereby blocking air or heat. Even if the user who manipulates the fire door accidentally inserts a finger (or hand) into the space formed between one side end of the fire door and the door frame, the wing piece is pushed inward by the pushing force of the finger, and thus the fire door is opened and closed when the fire door is opened and closed. It is pointed out as a problem that a safety accident occurs, where a finger gets caught in one end and is damaged.

또한, 상기 종래의 고무 밀폐 패킹은 단순히 상기 공간부를 얇은 형태의 날개편을 밀폐 시키는 것이어서 공기 차단력이 크게 저하됨은 물론, 외부의 열기가 내부로 침입할 수 있는 것이어서 단열 효과가 크게 저감되는 단점이 지적된다.In addition, the conventional rubber sealing packing simply seals the space portion of the thin-shaped wing piece, so that the air blocking power is greatly reduced, and the external heat can penetrate into the interior. do.
