Description

열감지형 도어스토퍼{THE DOOR STOPPER WITH HEAT SENSOR}Heat Sensing Door Stopper {THE DOOR STOPPER WITH HEAT SENSOR}

본원 발명은 화재시에 방화문을 자동으로 폐쇄할 수 있도록 하는 도어스토퍼에 관한 것으로, 구체적으로 평상시 개방된 상태를 유지하다가 화재시에 열에 의해서 변형되어 스토퍼의 기능이 해제되도록 하는 바이메탈을 포함하는 도어스토퍼에 관한 것이다.The present invention relates to a door stopper that allows a fire door to be automatically closed in case of a fire, and specifically, a door stopper including a bimetal that is deformed by heat in the event of a fire while maintaining the normally open state to release the function of the stopper. It is about.

최근 건축물은 고층화, 심층화,대형화 및 복합화에 따라 위험성이 증대되고, 화재시 인명과 재산 피해가 커지고 있다. 따라서, 방화구획 설계 및 관리를 강화하여 화재의 확산을 줄이고, 피난 안전성의 확보가 필요하다. 그 중에서 방화문은 화재의 확산을 방지하고 피난 또는 통행을 위하여 필수적인 요소다.In recent years, the dangers of buildings increase as high-rises, depths, enlargements and complexes increase, and in the event of a fire, life and property damage is increasing. Therefore, it is necessary to reduce the spread of fire and secure evacuation safety by strengthening the design and management of fire zones. Among them, fire doors are essential elements for preventing the spread of fire and for evacuation or passage.

방화문은 감지기 또는 센서에 의해서 자동으로 폐쇄되는 '상시개방형'과 도어클로저에 의해서 폐쇄되는 '상시폐쇄형'으로 구분된다. 상기 상시폐쇄형은 일반인의 통행이 드물거나 금지된 설비실 등에 설치되는데, 상기 설비실의 관리자 또는 작업자가 점검 또는 수리 등의 작업을 할 경우, 작업의 원활성을 위하여 방화문을 개방하고, 상기 개방된 방화문을 나무토막을 방화문문 하단 공간에 끼워놓거나, 방화문에 구비된 도어스토퍼를 이용해 개방된 상태로 고정시켜 놓는다.Fire doors are divided into'normally open type', which is automatically closed by a sensor or sensor, and'normally closed type', which is closed by a door closer. The normally closed type is installed in a facility room where the general public is not allowed to pass or is prohibited.When the manager or operator of the facility room performs work such as inspection or repair, the fire door is opened for smooth operation, and the opening The old fire door is inserted into the space below the fire door, or it is fixed in an open state using a door stopper provided on the fire door.

이때, 상기 작업자가 방화문을 폐쇄하는 것을 잊은채로 복귀하게 되면 방화문은 개방된 상태로 고정되어있어, 화재발생시에 방화문의 역할을 전혀 수행할 수 없게 된다. 이와 같이, 설비 등의 작업시에는 방화문이 개방된 상태를 유지할 수 있으며, 화재발생시 방화문이 자동으로 폐쇄되는 도어스토퍼가 요구된다. At this time, when the worker returns without forgetting to close the fire door, the fire door is fixed in an open state, so that it cannot perform the role of the fire door at all when a fire occurs. In this way, the fire door can be kept open when working with facilities, etc., and a door stopper is required that automatically closes the fire door when a fire occurs.

종래 선행문헌 1에 개시된 방화문 자동폐쇄장치는, 문틀 일측에 고정 설치하는 보디케이스와; 록킹수단에 의해 고정된 회전체의 록을 해제하는 언락피스톤과; 작동캠을 구비하여 상기 언락피스톤의 위치를 제어하는 정, 역회전 가능한 모터와; 상기 모터의 작동을 제어하는 제어부와; 방화문에 설치되는 도어클로저의 동작을 제어하는 회전체와; 상기 회전체와 결합되어 회전체의 작동력을 도어클로저에 전달하는 스윙암과; 상기 회전체의 위치를 고정하는 록킹수단을 포함하여 구성한다.A fire door automatic closing device disclosed in the prior art document 1 includes a body case fixedly installed on one side of a door frame; An unlocking piston for releasing the lock of the rotating body fixed by the locking means; A motor capable of forward and reverse rotation to control the position of the unlock piston by having an operation cam; A control unit for controlling the operation of the motor; A rotating body for controlling the operation of the door closer installed on the fire door; A swing arm coupled with the rotating body to transmit an operating force of the rotating body to the door closer; It comprises a locking means for fixing the position of the rotating body.

그러나, 이와 같은 방화문 자동폐쇄장치는 그 구조가 복잡하여 생산단가가 높을 뿐만 아니라, 무엇보다도 복잡한 구조로 인해서 오작동의 위험이 있기 마련이다. 이에 좀 더 간단한 구조에 의해서 저렴한 생산이 가능하고 더 신뢰성이 있는 방화문 자동폐쇄를 위한 수단이 요구되어 진다. However, such an automatic closing device for fire doors has a complex structure and a high production cost, and above all, there is a risk of malfunction due to a complex structure. Accordingly, a means for automatic closing of fire doors that can be produced inexpensively and more reliable by a simpler structure is required.

상기 몸체(10)는,The body 10,

반원의 프레임인 몸체(10)의 볼록한 면 중앙 상단에 일자형상으로 돌출된 프레임 두개가 서로 소정의 간격으로 이격되어 구비되는 돌출프레임(11)과Two frames projecting in a straight shape on the center top of the convex surface of the body 10, which is a semicircular frame, are spaced apart from each other at a predetermined interval, and

바람직하게, 상기 결합공(111)과 회동되게 연결하는 바이메탈레버(30)는 상단에 결합공(111)에 연결가능하게 원형의 연결핀을 구비한다.Preferably, the bimetallic lever 30 rotatably connected with the coupling hole 111 has a circular connection pin at the upper end to enable connection to the coupling hole 111.

상기 흡착판(20)은,The adsorption plate 20,

한쪽면은 상기 몸체(10)와 고정되고, 타면은 방화문(100)에 빨판의 원리로 흡착되어 몸체(10)를 방화문(100)에 고정시키는 역할이며,One side is fixed to the body 10, the other side is adsorbed to the fire door 100 by the principle of a sucker to fix the body 10 to the fire door 100,

상기 흡착면(21)은 안쪽이 오목한 고무로 이루어져 있으며, 평평한 방화문(100) 또는 문에 부착하게 되면, 공기의 기압의 차이로 인하여 기압이 낮은 흡착면 내부의 공기를 외부의 공기가 누르게 되어 고정되게 하고,The adsorption surface 21 is made of a concave rubber, and when attached to the flat fire door 100 or the door, the air inside the adsorption surface having a low atmospheric pressure due to the difference in the air pressure is pressed by outside air to be fixed. And

상기 바이메탈레버(30)는,The bimetallic lever 30,

바이메탈금속으로 이루어져 있는데,It is made of bimetallic metal,

바이메탈은 서로 다른 열팽창률을 가진 두 금속을 붙여서 만든 금속을 뜻하는데, 원사 또는 분자수준에서 섞은 합금과는 달리 거시적인 수준에서 둘을 섞지 않고 붙여만 놓은 것이다.Bimetal refers to a metal made by attaching two metals with different coefficients of thermal expansion. Unlike an alloy mixed at a yarn or molecular level, a bimetal is only attached without mixing the two at a macro level.

도 3과 같이, 상기 바이메탈에 열이 가해지면 두 금속이 팽창하게 되는데, 열팽창정도가 서로 다르므로 한 금속이 더 많이 팽창하게되되, 양끝이 고정되어 있어 단독으로 팽창할 수 없기때문에 결과적으로 열팽창 정도가 높은 금속이 열팽창 정도가 낮은 금속 쪽으로 휘어지게된다.As shown in FIG. 3, when heat is applied to the bimetal, the two metals expand. However, because the degree of thermal expansion is different, one metal expands more, but because both ends are fixed and cannot expand alone, the degree of thermal expansion as a result A metal with a higher degree of is bent toward a metal with a lower degree of thermal expansion.

바람직하게, 상기 바이메탈레버(30)는, 방화문 방향으로는 열팽창이 큰 금속인 제1금속(33)과, 방화문 반대방향으로 열팽창이 작은 금속인 제2금속(34)으로 이루어지고, 제1금속(33)과 제2금속(34)은 서로 고정되어 있다.Preferably, the bimetallic lever 30 is made of a first metal 33 that is a metal having a large thermal expansion in the direction of the fire door, and a second metal 34 that is a metal having a small thermal expansion in the direction opposite to the fire door, and the first metal 33 and the second metal 34 are fixed to each other.

이에 따라, 화재 발생시 제1금속(33) 및 제2금속(34)이 동시에 열팽창을 하게 되지만, 열팽창이 큰 제1금속(33)이 도 3과 같이, 제2금속(34) 방향으로 휘게되고, 제2금속(34) 방향인 방화문 반대방향으로 휘게된 제1금속(33) 및 제2금속(34)은 바이메탈레버(30)와 지지부(40)를 바닥에서 떨어뜨리게되며, 방화문이 도어클로저(200)에 의해 자동으로 닫히게 된다.Accordingly, when a fire occurs, the first metal 33 and the second metal 34 simultaneously thermally expand, but the first metal 33 having high thermal expansion is bent in the direction of the second metal 34 as shown in FIG. 3. , The first metal 33 and the second metal 34 bent in the direction opposite to the fire door, which is the direction of the second metal 34, separates the bimetal lever 30 and the support part 40 from the floor, and the fire door is a door closer. It is automatically closed by 200.

도 4는 본원 발명의 작동예를 나타내는 도면이다.4 is a view showing an example of the operation of the present invention.

도 4와 같이,상기 바이메탈을 도어스토퍼 레버에 적용하되, 열팽창 정도가 높은 금속을 방화문쪽으로 위치하게하여, 화재발생 시 열이 레버에 전달될경우, 방화문쪽에 위치한 금속이 방화문 맞은편에 위치한 금속보다 열팽창 정도가 낮으므로 방화문쪽 금속이 방화문의 바깥쪽으로 휘게됨과 동시에 레버가 상승하며, 방화문의 개방이 해제된다.As shown in Fig. 4, the bimetal is applied to the door stopper lever, but when heat is transferred to the lever when a fire occurs by placing a metal with a high degree of thermal expansion toward the fire door, the metal located on the fire door is higher than the metal located on the opposite side of the fire door. Since the degree of thermal expansion is low, the metal on the fire door is bent to the outside of the fire door, and the lever is raised at the same time, and the opening of the fire door is released.
