Description

도어스토퍼{door stoper}Door stoper

본 고안은 도어닫힘수단이 구비된 도어를 임의의 각도로 개방시킨 상태로 일시고정이 가능하고 화재발생시에는 자동으로 닫히는 방화문의 기능도 할수 있도록한 도어스토퍼에 관한 것이다.The present invention relates to a door stopper that can be temporarily fixed in a state in which a door having a door closing means is opened at an arbitrary angle and also functions as a fire door that automatically closes in the event of a fire.

일반적으로 건물의 출입문이나 방화문등은 도어닫힘방향으로 탄성복원력을 가진 회전작동체가 부착되고 상기 회전작동체의 회전축과 문틀사이에 두개의 작동간이 축핀으로 연결된 작동링크가 설치되어 도어를 자동으로 닫히도록한 도어닫힘수단이 구비되어 있다.In general, the door or the fire door of the building is attached to the rotating actuator having an elastic restoring force in the door closing direction, and the operation link is connected between the two shafts between the rotating shaft and the door frame of the rotating actuator by the shaft pin to automatically close the door. One door closing means is provided.

종래에도 상기와 같은 도어닫힘수단이 구비된 도어를 사용하여 도어를 자동으로 닫히게 할수 있었으며 도어를 임의의 각도의 개방상태로 고정할때에는 도어하부에 절첩식받침각을 설치하여 받침각을 펼쳐서 바닥면에 지지되게 한 스토퍼기능이나 도어하부에 쐐기를 끼워 스토퍼기능을 하도록 한 것이 있었으나 받침각의 절첩사용이 불편하고 쐐기는 분실의 우려도 있었다.Conventionally, it was possible to automatically close the door by using a door provided with the door closing means as described above. When fixing the door in an open state at an arbitrary angle, a folding angle is installed at the bottom of the door to extend the support angle to the bottom surface. There was a stopper function or a wedge attached to the lower part of the door to support the stopper function, but the use of folding angle of the supporting angle was inconvenient, and the wedge might be lost.

또한 상기 받침각과 쐐기를 도어스토퍼로 사용하는 경우에는 도어가 개방된 상태에서 화재발생시에 도어가 자동으로 닫혀서 화염을 차단하는 기능이 없었다.In addition, in the case of using the support angle and the wedge as the door stopper, the door was automatically closed in the event of a fire in the open state, and there was no function of blocking the flame.

이를 감안하여 판스프링으로된 탄성결합홈을 형성하여 회전작동축의 작동축에 연결된 작동간 하부에 걸림핀이 끼워져서 스토퍼기능을 하도록 한 것이 있었으나 이는 도어의 개방각도를 90도 또는 180도와 같이 어느 한정된 각도에서만 고정할수 있고 임의의 각도로 개방한 상태로 도어를 고정할수 없으므로 사용이 불편하였으며, 화재발생시에도 개방된 상태의 도어를 자동으로 닫히도록 한 것이 있었으나 상기 스토퍼해제수단은 납, 주석, 비스무트등의 용융합금으로된 스토퍼 해제가동구가 소정의 설정온도에서 용융되면 도어가 자동으로 닫히도록 되어 있은바 이는 화재발생시의 화염에 기준을 두지않고 온도에 따라 작동되게 한 것이어서 오작동의 발생우려와 함께 융융시점의 설정온도를 맞추는데도 어려움이 있었다.In view of this, an elastic coupling groove made of a leaf spring was formed so that a locking pin was inserted into the lower part of the operation connected to the operation shaft of the rotary operation shaft to stop the door. However, the opening angle of the door is limited to 90 degrees or 180 degrees. It was inconvenient to use because it could only be fixed at an angle and the door could not be fixed at an arbitrary angle, and the door was opened automatically even in the event of a fire, but the stopper release means was lead, tin, bismuth, etc. When the stopper release movable door made of molten alloy is melted at a predetermined set temperature, the door is automatically closed because it is operated according to the temperature without reference to the flame in case of fire. There was also a difficulty in adjusting the set temperature at the time.

본 고안은 이러한 문제점을 해결하기 위하여 회전작동체의 회전축 주위에 다수의 톱니형 고정홈이 형성된 반구형 고정판을 설치하고 회전축과 근접된 위치의 작동간에 쐐기형접촉자가 구비된 탄성작동체를 부착하여 접촉자를 고정판의 고정홈에 선택적으로 맞물리도록 한 수단으로 도어를 임의의 각도에 개방시킨 상태로 고정할수 있게하며, 탄성작동체는 지지레버로 탄성력을 유지케하고 지지레버는 섬유로된 안정끈으로 고정시킨 구성으로 화염에 의해 안전끝이 끓어지면 탄성작동체의 탄성력이 해제됨과 동시에 도어를 닫히게 하는 기능을 하도록 한 것이다.In order to solve this problem, the present invention installs a hemispherical fixing plate having a plurality of tooth-shaped fixing grooves around a rotating shaft of a rotating actuator, and attaches an elastic actuator having a wedge-shaped contactor between operations in a position close to the rotating shaft. Can be fixed in a state where the door is opened at an arbitrary angle by means of selectively engaging the fixing groove of the fixing plate, and the elastic actuator keeps the elastic force with the support lever and the support lever is fixed with the stabilizer made of fiber. When the safety tip is boiled by the flame, the elastic force of the elastic actuator is released and at the same time the door is closed.

In order to close the door by the operation link 14 is connected to the two operation between the operation 15, 15 'by the shaft pin 16, the hemispherical shape around the rotating shaft 13 of the rotary actuator 12 The fixing plate 20 is installed, but the inside of the fixing plate 20 forms a hollow portion 21 so that the operation part 15 connected to the rotating shaft 13 is not interfered, and the outer circumferential surface has a plurality of toothed fixing grooves 22. And the elastic actuator 30 having the wedge-shaped contactor 38 is attached to the operation section 15 in a position close to the rotation shaft 13 to fix the contactor 38 to the fixing groove 22 of the fixing plate 20. ) Can be selectively engaged.

상기 탄성작동체(30)는 작동간(15)에 볼트(31a)고정되는 고정관(31)과, 상기고정관(31)내부의 전방쪽에 슬라이드되게 끼워져서 후방의 압지스프링(40)에 의해 전방으로 탄성작용하도록한 접속관(35)과, 상기 접속관(35)은 전·후방에 축봉(36)(37)을 각각 축설하여 전방축봉(36)은 고정관(31)의 안내장공(32)내에 끼워져서 접속관(35)을 슬라이드안내되게 함과 아울러 전방축봉(36)에 접촉자(38)를 축설하며 접촉자(38)후단은 후방축봉(37)에 고정된 당김스프링(39)과 연결하여 당김작용으로 접촉자(38)의 선단접촉부(38a)가 일직선상으로 탄성지지되게한다.The elastic actuator 30 is fixed to the fixing tube 31 is fixed to the bolt (31a) between the operation 15, and the slide tube is inserted into the front of the inside of the fixing tube 31 to the front by the back pressure spring (40). The connection pipe 35 and the connection pipe 35 which are elastically actuated are arranged in the front and rear of the guide rod 32 of the fixed pipe 31 so that the front shaft rod 36 and 37 are laid out in front and rear, respectively. The contact tube 35 is inserted into the slide guide, and the contactor 38 is disposed on the front shaft rod 36, and the rear end of the contactor 38 is connected to the pull spring 39 fixed to the rear shaft rod 37. By action, the tip contact portion 38a of the contactor 38 is elastically supported in a straight line.

상기 압지스프링(40)은 압지스프링(40)후단에 설치된 나사조절봉(41)으로 접속관(35)을 전방으로 압지하는 탄성력을 조절할수 있게한다.The blotting spring 40 is able to adjust the elastic force to squeeze the connection pipe 35 to the front by the screw adjustment rod 41 installed at the rear of the blotting spring (40).

나사조절봉(41)이 결합되는 고정나사관(42)은 고정관(31)에 슬라이드되게 끼워져서 지지레버(43)에 의해 탄성력을 유지할수 있게 고정하되 지지레버(43)는 분리형으로 구성하고 후단부내측에 결합홈(44)과 결합돌기(45)를 각각 형성하여 고정나사관(42)후단의 걸림돌기(41a)와 고정관(31)후단의 걸림홈(33)에 대응결합되고 지지레버(43)전단부외측은 고정홈(46)을 형성하여 섬유로 된 안전끈(47)으로 지지레버(43)를 고정관(31)외측의 고정홈(34)에 결착하여 지지되게 한 것이다.Screw screw rod 42 is coupled to the fixing screw tube 42 is inserted into the fixed tube 31 to be slid so as to maintain the elastic force by the support lever 43, but the support lever 43 is configured to be separated after Coupling grooves 44 and coupling protrusions 45 are respectively formed on the inner side of the end to correspond to the locking projections 41a at the rear end of the fixing screw pipe 42 and the locking grooves 33 at the rear end of the fixing pipe 31, respectively. 43) The outside of the front end portion is formed by the fixing groove 46 to secure the support lever 43 to the fixing groove 34 outside the fixing pipe 31 by the safety strap 47 made of fiber to be supported.

이와같이 된 본 고안의 도어스토퍼는 도어를 여닫는 과정에서는 도어에 가해지는 힘에 의해서 탄성작동체(30)는 접촉자(38)의 선단접촉부(38a)가 반구형고정판(20)의 고정홈(22)에 끼워지지 않고 전방축봉(36)을 축으로하여 비스듬하게 기울어져서 진행하게 된다.In the door stopper according to the present invention, the front end of the contactor 38 is fixed to the fixing groove 22 of the hemispherical fixing plate 20 by the force applied to the door in the process of opening and closing the door. It does not fit and advances at an oblique angle with the front shaft bar 36 as an axis.

즉, 도 8에서와 같이 도어를 열고 닫을 때는 도어에 가해지는 힘에 의해 진행방향으로 접촉자(38)의 선단접촉부(38a)가 비스듬하게 기울어진 상태로 놓여지게되는바 도어를 여는 방향으로 힘이 가해져서 접촉자(38)의 선단접촉부(38a)가 기울어진 다음 반대방향으로 도어에 닫는 힘이 가해지게 되면 접촉자(38)가 약간 후방으로 밀리면서 접촉자(38)의 선단접촉부(38a)가 반대방향으로 기울어져서 회전작동체(12)의 탄성복원력에 의해 닫히게 된다.That is, as shown in FIG. 8, when the door is opened and closed, the tip contact portion 38a of the contactor 38 is inclined obliquely in the traveling direction due to the force applied to the door. When the tip contact portion 38a of the contactor 38 is applied and the closing force is applied to the door in the opposite direction, the contactor 38 is pushed back slightly and the tip contact portion 38a of the contactor 38 is reversed. It is inclined to close by the elastic restoring force of the rotary actuator 12.

한편, 도어를 임의의 각도를 개방시킨 상태에서 그 개방지점에서 일시적인 고정을 하고자 할때에는 도 9에서와 같이 도어의 개방지점에서 반구형고정판(20)의 고정홈(22)에 접촉자(38)의 선단접촉부(38a)가 끼워진 상태로 정시키면 선단접촉부(38)가 압지스프링(40)의 가해지는 힘과 일직선상으로 놓여지면서 압지스프링(40)의 가압력에 의해 접촉자(38)의 선단접촉부(38a)가 반구형고정판(20)의 고정홈(22)에 고정된 상태를 유지하여 도어가 닫히지 않고 도어를 개방위치에서 일시 고정하게 된다.On the other hand, when the door is to be temporarily fixed at its open position with an arbitrary angle open, as shown in FIG. 9, the tip of the contactor 38 in the fixing groove 22 of the hemispherical fixing plate 20 at the opening point of the door. When the contact portion 38a is set in the fitted state, the tip contact portion 38 is placed in line with the force applied by the presser spring 40, and the tip contact portion 38a of the contactor 38 is pressed by the pressing force of the presser spring 40. The state is fixed to the fixing groove 22 of the hemispherical fixing plate 20 to temporarily fix the door in the open position without closing the door.

이렇게 도어를 개방하여 정지된 상태로 놓여지면 접촉자(38)의 선단접촉부(38a)가 반구형고정판(20)의 고정홈(22)에 끼워져서 고정된 상태를 유지하게 되고 이러한 도어에 닫히는 방향으로 힘이 가해지면 접촉자(38)의 선단접촉부(38a)가 비스듬하게 기울어지면서 회전작동체(12)의 탄성복원력에 의해 닫히게 된다.When the door is opened and placed in the stopped state, the tip contact portion 38a of the contactor 38 is inserted into the fixing groove 22 of the hemispherical fixing plate 20 to maintain the fixed state, and the force in the direction of closing the door When this is applied, the tip contact portion 38a of the contactor 38 is inclined obliquely and is closed by the elastic restoring force of the rotary actuator 12.

또한, 상기와 같이 도어를 임의의 각도로 개방하고 있는 상태에서 화재가 발생하여 화염에 의해 탄성작동체(12)의 고정관(31)에 지지레버(43)를 결착하고 있는 섬유로 된 안전끈(47)이 끓어지면 지지레버(43)가 벌어짐과 동시에 지리레버(43)에 결합된 압지스프링(40)의 탄발력에 의해 고장나사관(42)이 후방으로 밀려나가면서접속관(35)이 후방으로 슬라이드됨과 아울러 접촉자(38)의 선단접촉부(38a)는 압지스프링(40)의 탄성력이 없어져서 반구형고정판의 고정홈(46)에서의 고정상태가 해제되어 회전작동체(12)의 탄성복원력으로 도어가 자동으로 닫혀 방화문기능을 하게 된다.Further, as described above, a fire occurs in a state in which the door is opened at an arbitrary angle, and a safety strap made of fiber binding the support lever 43 to the fixing tube 31 of the elastic actuator 12 by a flame ( When 47) is boiled, the support lever 43 is opened and at the same time, the screw thread 42 is pushed backward by the elastic force of the urge spring 40 coupled to the geographic lever 43, and the connection pipe 35 is rearward. In addition, the front end contact portion 38a of the contactor 38 is removed from the elastic force of the blotting spring 40, thereby releasing the fixed state in the fixing groove 46 of the hemispherical fixing plate, and the door by the elastic restoring force of the rotary actuator 12. Automatically closes and acts as a fire door.

이와같이 본 고안의 도어스토퍼는 다수의 톱니형고정홈에 접촉자를 선택적으로 고정할수 있도록 한 수단으로 도어를 임의의 각도로 개방시킨 상태로 일시고정을 편리하게 할수 있고 화재발생시에는 화염에 의해서만 도어를 자동으로 닫히게 하므로 방화문기능을 오작동없이 정확하게 할수 있는 이점이 있다.As such, the door stopper of the present invention can conveniently fix the door by opening the door at an arbitrary angle by means of selectively fixing the contactor to a plurality of toothed fixing grooves, and automatically opens the door only by the flame in case of fire. Because it is closed by the door, there is an advantage that the fire door function can be accurately performed without malfunction.
