방화도어용 클로져기구 {Closure device for fire prevention door}Closure device for fire doors {Closure device for fire prevention door}

본 발명은 방화도어용 클로져기구에 관한 것으로, 더욱 상세하게는 화재시 방화도어의 규격에 부합하여 신속하고 강력한 폐쇄가 가능하면서 평상시 개방작동의 용이성과 원활성을 보장하기 위한 방화도어용 클로져기구에 관한 것이다.The present invention relates to a closure mechanism for a fire door, and more particularly to a closure door for a fire door to ensure the ease and smoothness of the usual opening operation while enabling a quick and powerful closing in accordance with the specifications of the fire door in the event of fire. It is about.

도 1은 종래의 방화도어용 클로져기구를 나타내는 사시도이다.1 is a perspective view showing a conventional closure mechanism for fire doors.

통상적으로 콘크리트 건축물에서 설치되는 방화용도어는 도어의 개폐 작동을 원활하게 하면서 소방 관련법 규정상의 방화기능을 수행하기 위한 클로져기구가 설치된다. 이와 같은 클로져기구는 소방법 규정의 준수를 위해 통상적인 본체(10) 외에 보조기구(20)를 구비한다.Fire doors that are usually installed in a concrete building is provided with a closure mechanism for performing the fire protection function in accordance with the laws of fire protection while smoothly opening and closing the door. Such a closure mechanism is provided with an auxiliary mechanism 20 in addition to the normal body 10 for compliance with fire law regulations.

그런데 근래의 개정 소방 관련법에 따르면 방화문의 자동 폐쇄 기능을 강화하는 바, 보조기구(20)는 화재 발생시 실내외의 압력차를 극복하고 도어를 폐쇄하는 힘을 증강하는 기능을 지닌다. 다만 화재시 신속하고 강력한 폐쇄기능을 수행하는 동시에 평상시 도어를 개방할 때 60N 이하의 힘에서도 작동이 가능해야 하는 점도 고려되어야 한다.By the way, according to the recent revision of the fire protection law to reinforce the automatic closing function of the fire door, the auxiliary mechanism 20 has the function to overcome the pressure difference between the indoor and outdoor and to increase the power to close the door in the event of a fire. However, it should be taken into account that it should be able to operate at a force of 60 N or less when opening the door at the same time as it performs fast and strong closing function in case of fire.

그러나 종래의 클로저기구는 이와 같은 상반되는 양면의 기능을 수행하기에 적합하지 않다. 즉, 개정 소방법 규정에 부합하기 위해서는 클로져기구가 종래보다 약 1.5배~2배가량 커져야 하며, 클로저기구의 크기가 증강됨에 따라 실내압력의 강화로 인하여 문이 자동으로 닫히는 작동이 원활하다. 그 반면에 평상시 도어를 개방하는 힘도 동시에 증가하므로 노약자나 어린이 등이 방화문을 개방하기가 어려운 문제가 발생한다.However, conventional closure mechanisms are not suitable for performing these opposing two-sided functions. That is, in order to comply with the provisions of the revised fire law, the closure mechanism should be about 1.5 to 2 times larger than the conventional one. As the size of the closure mechanism is increased, the door is automatically closed due to the strengthening of the indoor pressure. On the other hand, since the power to open the door at the same time increases, it is difficult for the elderly and children to open the fire door.

본 발명은 화재시 방화도어의 규격에 부합하여 신속하고 강력한 폐쇄가 가능하면서 평상시 개방작동의 용이성과 원활성을 보장하기 위한 방화도어용 클로져기구를 제공하는데 그 목적이 있다.An object of the present invention is to provide a closure mechanism for a fire door to ensure the ease and smoothness of the usual opening operation while being able to close quickly and powerfully in accordance with the specifications of the fire door in the event of fire.

본 발명은 도어클로져의 본체에 연결되어 화재시 도어의 신속ㆍ강력한 폐쇄와 평상기 도어의 용이ㆍ원활한 개방이 가능하도록 하는 클로져기구에 있어서: 하우징의 내부에 스프링을 개재하여 설치되고, 선단에 그루우브를 지니는 작동자; 상기 작동자의 그루우브 상에 직선운동 가능하게 수용되는 볼; 및 상기 작동자 상의 볼을 활주로 상으로 유도하면서 본체에 의한 도어회전력을 다단계로 변동하는 작동실린더;를 포함하여 이루어지는 것을 특징으로 한다.The present invention is a closure mechanism connected to the main body of the door closer to enable the quick and strong closing of the door in the event of fire and the easy and smooth opening of the door in general: a spring is provided inside the housing via a spring, An operator with a web; A ball accommodated linearly on the groove of the operator; And an operating cylinder for varying the door rotational power by the body in multiple stages while guiding the ball on the operator onto the runway.

또한, 본 발명에 따른 상기 작동실린더는 원통형 외주면상에 일정폭의 홈을 주걱 형상으로 연결하여 볼의 순환 이동을 유도하는 활주로를 구비하되, 제1활주로는 깊이의 변화가 없고, 제2활주로는 제1하강턱에 이를 때까지 깊이가 완만하게 증가하고, 제3활주로는 깊이가 급격하게 증가한 직후 완만하게 감소하며 제2낙하턱을 통해 제1활주로 또는 제2활주로와 연통되는 것을 특징으로 한다.In addition, the operation cylinder according to the present invention is provided with a runway for inducing a circular movement of the ball by connecting a groove of a predetermined width on the cylindrical outer peripheral surface in the spatula shape, the first runway does not change the depth, the second runway The depth gradually increases until the first lower jaw is reached, and the third runway gradually decreases immediately after the depth sharply increases, and the third runway communicates with the first runway or the second runway.

또한, 본 발명에 따른 상기 작동실린더는 볼의 운동범위를 제한하기 위한 절단면 또는 스토퍼를 구비하는 것을 특징으로 한다.In addition, the operating cylinder according to the invention is characterized in that it has a cutting surface or stopper for limiting the range of motion of the ball.

본 발명의 방화도어용 클로져기구는 화재시 방화도어의 규격에 부합하여 신속하고 강력한 폐쇄가 가능하면서 평상시 개방작동의 용이성과 원활성을 보장할 수 있는 효과가 있다.The closure mechanism for a fire door of the present invention has the effect of ensuring the ease and smoothness of the usual open operation while being able to close quickly and powerfully in accordance with the specifications of the fire door in the event of fire.

본 발명을 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명에 의한 클로져기구를 분해하여 나타내는 사시도, 도 3은 도 2의 요부를 분해하고 확대하여 나타내는 사시도, 도 4는 도 3의 작동실린더를 분리하고 확대하여 나타내는 사시도이다.2 is an exploded perspective view showing the closure mechanism according to the present invention, FIG. 3 is an exploded perspective view showing the main portion of FIG. 2 in an enlarged state, and FIG. 4 is a perspective view showing the enlarged separation and operation cylinder of FIG.

본 발명은 도어클로져의 본체(10)에 연결되어 화재시 도어의 신속ㆍ강력한 폐쇄와 평상기 도어의 용이ㆍ원활한 개방이 가능하도록 하는 클로져기구에 관련된다. 통상 도어는 180° 까지 문의 개방이 가능한데 폐쇄시 15∼20° 범위에서 매우 천천히 닫히면서 힘이 세야 하나 초창기의 클로져기구는 힘이 세지 않아 문이 잘 닫히지 않는 단점이 있다. 이후 작동력을 증강하여 폐쇄하는 기술이 적용되기는 하지만 반면에 도어의 개방시 그에 상응한 세기의 힘이 소요되므로 사용자에게 외면당하는 문제점이 있다. 본 발명에 의한 클로져기구를 이루는 보조기구(30)도 본체(10)에 브라켓(15)을 개재하여 연결된다.The present invention relates to a closure mechanism which is connected to the main body 10 of the door closer to enable quick and strong closing of the door in case of fire and easy and smooth opening of the door. Normally, the door can be opened up to 180 °, but when it is closed, the door is closed very slowly in the range of 15 to 20 °. However, the early closure mechanism has a disadvantage that the door does not close well because of the strong force. Since the technology to close the operation force is applied afterwards, while the strength of the corresponding strength is required when opening the door, there is a problem that the user is turned away. The auxiliary mechanism 30 constituting the closure mechanism according to the present invention is also connected to the main body 10 via the bracket 15.

본 발명에 따르면 선단에 그루우브(35a)를 지니는 작동자(35)가 하우징(31)의 내부에 스프링(32)을 개재하여 설치된다. 작동자(35)가 도 1의 작동자(25)처럼 스프링(32)과 마개(23)에 의해 탄지되는 점은 종래와 동일하다. 다만 본 발명의 작동자(35)는 선단에 일정한 폭과 깊이의 그루우브(35a)를 지니며, 후술하는 원통형 의 작동실린더(40)와 외접하도록 선단이 경사지게 형성된다.According to the present invention, the operator 35 having the groove 35a at the tip is installed through the spring 32 in the housing 31. The operator 35 is carried by the spring 32 and the stopper 23 like the operator 25 of FIG. 1 as in the prior art. However, the operator 35 of the present invention has a groove 35a of a predetermined width and depth at the tip, and the tip is inclined so as to be external to the cylindrical operation cylinder 40 to be described later.

또, 본 발명에 따르면 상기 작동자(35)의 그루우브(35a) 상에 볼(38)이 직선운동 가능하게 수용된다. 종래의 경우 작동자(25)와 작동판(24)이 캠기구를 구성하는 반면 본 발명은 작동자(35)와 후술하는 작동실린더(40)가 볼(38)을 매개로 하여 캠기구를 구성한다. 따라서 볼(38)은 비교적 큰 작용력이 전달되므로 작동자(35)와 작동실린더(40)에 버금가는 강도와 경도를 요한다. 볼(38)이 작동자(35)의 그루우브(35a) 상에서 직선운동을 수행하는 것은 후술하는 작동실린더(40)의 활주로(42)(44)(46)와 연계되기 때문이다.Further, according to the present invention, the ball 38 is accommodated in a linear motion on the groove 35a of the operator 35. In the conventional case, the operator 25 and the operating plate 24 constitute a cam mechanism, while in the present invention, the operator 35 and the operation cylinder 40 to be described below constitute the cam mechanism via a ball 38. do. Therefore, the ball 38 requires a strength and hardness comparable to that of the operator 35 and the working cylinder 40 because a relatively large force is transmitted. The reason why the ball 38 performs a linear motion on the groove 35a of the operator 35 is because it is associated with the runways 42, 44 and 46 of the operation cylinder 40 described later.

또, 본 발명에 따르면 작동실린더(40)가 상기 작동자(35) 상의 볼(38)을 활주로(42)(44)(46) 상으로 유도하면서 본체(10)에 의한 도어회전력을 다단계로 변동한다. 작동실린더(40)는 종래의 작동판(24)처럼 캠운동을 유발하여 본체(10) 및 도어에 대한 탄성력을 조절하지만 원통형 외주면상에 일정폭의 홈을 주걱 형상으로 연결하여 볼(38)의 순환 이동을 유도하는 활주로(42)(44)(46)를 구비한다. 주걱 형상은 제1활주로(42)를 자루로 하고 여기에 제2활주로(44)와 제3활주로(46)가 원형으로 연결되는 형태를 의미한다. 이러한 형태는 볼(38)이 각각 제1활주로(42), 제2활주로(44), 제3활주로(46)를 거쳐 다시 제1활주로(42)로 복귀하여 반복적으로 순환하는 구성을 구현한다.In addition, according to the present invention, the operation cylinder (40) guides the ball (38) on the operator (35) onto the runway (42) (44) (46) while varying the door rotational force by the main body (10) in multiple stages. do. The operation cylinder 40 adjusts the elastic force for the main body 10 and the door by inducing a cam motion like the conventional operation plate 24, but by connecting a groove of a predetermined width in a spatula shape on the cylindrical outer circumferential surface of the ball 38 Runways 42, 44 and 46 for circulating movement. The spatula shape refers to a form in which the first runway 42 is a bag and the second runway 44 and the third runway 46 are connected in a circle. This form implements a configuration in which the ball 38 returns to the first runway 42 again and again through the first runway 42, the second runway 44, and the third runway 46, respectively.

이때, 본 발명에 따르면 제1활주로(42)는 깊이의 변화가 없고, 제2활주로(44)는 제1하강턱(45)에 이를 때까지 깊이가 완만하게 증가하고, 제3활주로(46)는 깊이가 급격하게 증가한 직후 완만하게 감소하며 제2낙하턱(47)을 통해 제1활주 로(42) 또는 제2활주로(44)와 연통된다. 제1활주로(42)의 깊이 변화가 없는 것은 작동자(35)의 변위에 영향을 주지 않으며 따라서 본체(10)에 대한 작용력도 일정한 상태이다. 제2활주로(44)가 제1하강턱(45)에 이를 때까지 깊이가 완만하게 증가하는 것은 도어의 폐쇄시 일정각도까지 폐쇄력을 일정하게 증가시키는 것을 의미한다. 이후 볼(38)이 제1하강턱(45)을 통과하면서 급격하게 깊이가 증가한 후 최저점에 이르는데, 이에 따라 도어가 힘차게 닫힌 후 정지 상태에 이른다. 다음에 도어를 개방하는 경우 볼(38)이 제3활주로(46) 상에서 최저점에서 이동하여 완만하게 상승하면서 개방력에 큰 부담을 주지 않고, 어느 정도 개방이 진행되면 다시 제2낙하턱(47)을 통과하여 제1활주로(42) 또는 제2활주로(44)에 이르므로 초기의 상태로 복귀된다.At this time, according to the present invention, the first runway 42 has no change in depth, and the second runway 44 gradually increases in depth until reaching the first lower jaw 45, and the third runway 46. The gradual decrease immediately after the depth increases sharply and communicates with the first runway 42 or the second runway 44 through the second drop jaw 47. The absence of a change in depth of the first runway 42 does not affect the displacement of the operator 35 and therefore the action force on the body 10 is also constant. Slowly increasing the depth until the second runway 44 reaches the first lower jaw 45 means that the closing force is constantly increased to a certain angle when the door is closed. After the ball 38 passes through the first lower jaw 45, the depth sharply increases and reaches the lowest point. As a result, the door closes forcefully and reaches a stop state. Next, when opening the door, the ball 38 moves from the lowest point on the third runway 46 and ascends gently, without placing a large burden on the opening force. It passes through and reaches the 1st runway 42 or the 2nd runway 44, and it returns to an initial state.

이와 같이 도어의 폐쇄와 개방이 반복되는 동안 볼(38)은 작동실린더(40)의 활주로(42)(44)(46)를 따라 순환하며 스프링(32)에 대한 작동자(35)의 변위를 가변하고 이에 따라 본체(10)에 대한 보조 작동력이 적절히 증감될 수 있다.As such, while the closing and opening of the door are repeated, the ball 38 circulates along the runways 42, 44, 46 of the actuating cylinder 40 and the displacement of the operator 35 relative to the spring 32. The auxiliary operating force on the body 10 can thus be varied accordingly.

도 5는 본 발명의 변형예에 의한 작동실린더를 나타내는 구성도, 도 6은 본 발명의 다른 변형예에 의한 작동실린더를 나타내는 구성도이다. 5 is a configuration diagram showing an operation cylinder according to a modification of the present invention, Figure 6 is a configuration diagram showing an operation cylinder according to another modification of the present invention.

상기 작동실린더(40)는 볼(38)의 운동범위를 제한하기 위한 절단면(55) 또는 스토퍼(65)를 구비한다. 도 5의 절단면(55)은 볼(38)이 운동하지 않는 부분을 배제한 형태로서 양산시 소재 절감에 의한 이득이 예상된다. 도 6의 스토퍼(65)는 볼(38)의 운동범위를 제한하여 오작동을 방지한다. 물론 도 5와 도 6의 구성을 병용하는 것도 가능하다.The working cylinder 40 has a cutting surface 55 or stopper 65 for limiting the range of motion of the ball 38. The cut surface 55 of FIG. 5 is a form in which the ball 38 does not move and is expected to benefit from material savings during mass production. The stopper 65 of FIG. 6 limits the range of motion of the ball 38 to prevent malfunction. Of course, it is also possible to use together the structure of FIG. 5 and FIG.

도 7은 본 발명에 의한 클로져기구의 결합 및 작동상태를 나타내는 구성도이다.Figure 7 is a block diagram showing the engagement and operation of the closure mechanism according to the present invention.

본 발명은 클로져기구의 하우징(31) 내에 작동실린더(40)가 설치되고 그 외주면 접선 방향으로 작동자(35)가 볼(38)을 개재하여 설치된다. 도어의 개폐에 따라 본체(10)의 회전변위(작용력)가 변화할 때 작동실린더(40)도 이에 연동하여 회전변위의 변동이 유발된다. 이러한 변위의 변동은 작동실린더(40)의 활주로(42)(44)(46)에 수용된 볼(38)을 통하여 작동자(35)와 스프링(32)의 탄성력 변화를 유발한다. 본 발명에 의한 작동실린더(40)의 활주로(42)(44)(46)가 설정된 캠프로파일을 구현하기 위한 다단의 깊이로 형성되므로 볼(38) 및 작동자(35)와 연계하여 상대적으로 복잡한 제어가 가능하다.In the present invention, the operation cylinder 40 is installed in the housing 31 of the closure mechanism, and the operator 35 is installed via the ball 38 in the tangential direction of the outer peripheral surface thereof. When the rotational displacement (action force) of the main body 10 changes in accordance with the opening and closing of the door, the operation cylinder 40 also interlocks with this, causing variation in the rotational displacement. This variation in displacement causes a change in the elastic force of the operator 35 and the spring 32 through the balls 38 received in the runways 42, 44, 46 of the actuating cylinder 40. Since the runway 42, 44, 46 of the operation cylinder 40 according to the present invention is formed at a depth of multiple stages for implementing the set camp profile, the ball 38 and the operator 35 are relatively connected. Complex control is possible.

한편, 개정 소방법 규정에 적합하기 위해서는 도어의 닫히는 힘은 셀수록 좋고, 열리는 힘은 5.5kg(60N) 이하가 되어야 한다. 종래의 경우 전자와 후자의 조화가 곤란하나 본 발명에 의하면 일정구간(폐쇄직전의 15-20°)에서 닫히는 힘을 강화하면서 반대로 열리는 힘은 부드럽게 유지할 수 있다. On the other hand, in order to comply with the revised fire regulations, the closing force of the door is better and the opening force should be less than 5.5kg (60N). In the conventional case, it is difficult to harmonize the former and the latter, but according to the present invention, while maintaining the closing force in a certain section (15-20 ° immediately before closing), the opposite opening force can be kept soft.
