방화문(防火門)의 힌지장치{HINGE DEVICE FOR A FITE DOOR} Hinge DEVICE FOR A FITE DOOR

본 발명은 방화문(防火門)의 힌지장치에 관한 것으로, 더욱 상세하게는 문틀에 고정되는 상부지지판과 방화문의 상부면에 고정되는 하부지지판 사이에 끼워져 설치되는 힌지축상에 베어링이 상하방향으로 유동되게 끼워지도록 구성함으로써 조립 및 수리작업성이 크게 향상될 수 있도록 하고, 방화문의 개폐동작이 한층 원활하게 이루어질 수 있도록 한 방화문의 힌지장치에 관한 것이다. The present invention relates to a hinge device of the fire door (더욱 火 門), and more particularly to the bearing flows in the vertical direction on the hinge shaft is installed between the upper support plate fixed to the door frame and the lower support plate fixed to the upper surface of the fire door. It is related to the hinge device of the fire door to be assembled so that the assembly and repair workability can be greatly improved, and the opening and closing operation of the fire door can be made more smoothly.

일반적으로, 방화문(防火門)은 건물이나 선박 등에서의 화재발생시 화염 및 연기가 다른 공간으로 확대되는 것을 방지하기 위하여 건물의 개구부에 설치하는 문을 말하는 것으로, 통상 내화성(耐火性)의 금속으로 제조된다.In general, a fire door is a door installed in an opening of a building to prevent the expansion of flames and smoke into another space in the event of a fire in a building or a ship, and is usually made of a fire-resistant metal. do.

한편, 상기 방화문이 여닫이방식으로 개폐되도록 하기 위해서는 문틀과 방화문사이에 별도의 힌지장치가 설치되는데, 종래의 방화문의 힌지장치(10)는 도 1 내지 도 3에 도시된 바와 같이, 문틀에 고정되는 상부지지판(12)과, 상기 상부지지판(12)과 대응되는 위치에 해당되는 방화문(14)의 상부에 고정·설치되는 하부지지판(16) 및 상기 하부지지판(16)으로부터 수직 상방향으로 돌출되게 설치된 상태에서 상부지지판(12)에 끼워져 결합되어 방화문(14)과 함께 회전되는 힌지축(18)으로 이루어진다.On the other hand, a separate hinge device is installed between the door frame and the fire door in order to open and close the fire door in the opening and closing manner, the hinge device 10 of the conventional fire door is fixed to the door frame, as shown in Figs. Protrude from the upper support plate 12 and the lower support plate 16 and the lower support plate 16 which are fixed and installed on the upper portion of the fire door 14 corresponding to the position corresponding to the upper support plate 12. The hinge shaft 18 is rotated together with the fire door 14 by being coupled to the upper support plate 12 in the installed state.

이와 같이 이루어지는 종래 방화문의 힌지장치(10)에서는 상기 하부지지판(16)의 상부면 중심부에 힌지축(18)이 나사결합방식으로 끼워져 결합되도록 하기 위한 나사공(16a)이 형성되고, 상기 상부지지판(12)의 하부면 중심부에는 힌지축(18)의 윗부분이 끼워지는 축받이공(12a)이 형성되는 한편, 상기 축받이공(12a)에는 방화문(14)의 개폐동작에 따른 힌지축(18)의 회전동작이 원활하게 이루어지도록 하기 위한 베어링(20)이 끼워져 결합되도록 구성된다.In the hinge device 10 of the conventional fire door made as described above, a screw hole 16a is formed at the center of the upper surface of the lower support plate 16 so that the hinge shaft 18 is fitted by a screwing method, and the upper support plate is formed. A bearing hole 12a is formed in the center of the lower surface of the hinge shaft 18 so that the upper portion of the hinge shaft 18 is fitted, while the bearing hole 12a has a hinge shaft 18 according to the opening and closing operation of the fire door 14. The bearing 20 is inserted and coupled to facilitate the rotation operation.

그러나, 이와 같이 이루어지는 종래 방화문의 힌지장치(10)에서는 힌지축(18)의 회전동작이 원활하게 이루어지도록 하기 위한 베어링(20)이 상부지지판(12)상의 축받이공(12a) 내부에 수납·설치되는 구조로 이루어지기 때문에 그 조립 및 수리작업성이 매우 불량하다는 문제가 있다.However, in the hinge device 10 of the conventional fire door made as described above, the bearing 20 for smoothly rotating the hinge shaft 18 is stored and installed in the bearing hole 12a on the upper support plate 12. There is a problem that the assembly and repair work is very poor because it is made of a structure.

There is a serious problem that the opening and closing of the door is not made quickly in case of emergency such as fire.

또, 상기 힌지축(18)의 아랫부분이 하부지지판(16)상의 나사공(16a)에 나사결합된 후 별도의 고정핀(22)에 의하여 고정되기 때문에 조리작업이 매우 불편하다는 문제가 있다.In addition, since the lower portion of the hinge shaft 18 is screwed to the screw hole (16a) on the lower support plate 16 is fixed by a separate fixing pin 22 there is a problem that the cooking operation is very inconvenient.

본 발명은 이와 같은 종래의 문제점을 해결하기 위한 것으로, 그 목적은 문틀에 고정되는 상부지지판과 방화문의 상부면에 고정되는 하부지지판 사이에 끼워져 설치되는 힌지축상에 베어링이 상하방향으로 유동되게 끼워지도록 구성함으로써 조립이 간편하게 이루어질 수 있도록 한 새로운 방화문의 힌지장치를 제공하는 것이다.The present invention is to solve such a conventional problem, the object is to be fitted so that the bearing flows in the vertical direction on the hinge shaft is installed between the upper support plate fixed to the door frame and the lower support plate fixed to the upper surface of the fire door. It is to provide a new fire door hinge device to facilitate the assembly by configuring.

When it is inserted into the shaft coupling hole 46a on the support plate 46 and then the fixing pin 52 is screwed through the fixing pin coupling hole 56 from the outer side of the lower support plate 46, the fixing pin ( Since the tip of 52) reaches the inner side of the shaft coupling hole 46a to press the outer circumferential surface of the lower portion of the hinge shaft 48, the hinge shaft 48 is fixed in the state of being fitted in the shaft coupling hole 46a.

이와 같이 하여 하부지지판(46)의 축결합공(46a)에 끼워진 힌지축(48)의 윗부분을 상부지지판(42)상의 축받이공(42a)에 맞추어 끼우면 방화문(44)의 설치가 완료된다.In this way, when the upper portion of the hinge shaft 48 fitted in the shaft coupling hole 46a of the lower support plate 46 is fitted to the bearing hole 42a on the upper support plate 42, the installation of the fire door 44 is completed.

이 상태에서 상기 방화문(44)을 여닫이 방식으로 개폐시키면 상기 힌지축(48)이 축받이공(42a)에 끼워진 상태에서 방화문(44)의 개폐방향으로 회전되는데, 상기 축받이공(42a)과 힌지축(48) 사이에 베어링(50)이 개재되어 있기 때문에 방화문(44)의 개폐동작이 원활하게 이루어지는 것이다.When the fire door 44 is opened and closed in this state, the hinge shaft 48 is rotated in the opening and closing direction of the fire door 44 in a state where the hinge shaft 48 is fitted in the bearing hole 42a, and the bearing hole 42a and the hinge shaft are closed. Since the bearing 50 is interposed between the 48, the opening / closing operation of the fire door 44 is performed smoothly.

한편, 상기 베어링(50)은 힌지축(48)의 윗부분에 끼워져 결합된 상태에서 상하방향으로 유동되기 때문에 무거운 방화문(44)의 하중에 의하여 힌지축(48)이 약간 어긋난 상태가 되더라도 방화문(44)의 개폐동작에 전혀 지장을 초래하지 않게 된다. On the other hand, since the bearing 50 is inserted into the upper portion of the hinge shaft 48 and flows in the up and down direction, even if the hinge shaft 48 is slightly displaced by the load of the heavy fire door 44, the fire door 44 It does not cause any trouble to the opening and closing operation of
