Description

도어클로저용 폐쇄력 증강장치{CLOSING POWER REINFORCEMENT DEVICE FOR DOOR CLOSER}Closing force enhancer for door closer {CLOSING POWER REINFORCEMENT DEVICE FOR DOOR CLOSER}

본 발명은 도어클로저용 폐쇄력 증강장치에 관한 것으로서 더욱 상세하게는 가정이나 사무실에 설치되는 도어(방화문 또는 현관문)가 닫혀 질 때 힘을 증강시켜 완전하게 닫힘 상태를 유지할 수 있도록 하는 도어클로저용 폐쇄력 증강장치의 제공에 관한 것이다.The present invention relates to a closing force enhancer for a door closer, and more particularly, for a door closer to maintain a completely closed state by increasing the force when the door (fire door or front door) installed in a home or office is closed. It relates to the provision of a closing force enhancer.

도어클로저는 가정이나 상업용 건축물에 설치되는 현관 또는 피난계단, 재연구역 방화문에 설치되어 화재발생시 또는 이용자가 직접적으로 힘을 가하지 않더라도 도어가 완전하게 닫힘상태를 유지하도록 하는 것이다.The door closer is installed in the entrance door, evacuation stairs, and reenactment fire doors installed in homes or commercial buildings to keep the door completely closed even in the event of a fire or even if the user does not apply force directly.

이러한 도어클로저(1)는 도 7에 도시된 바와 같이, 도어프레임(2)에 장착되어 유압 또는 스프링를 내장하여 작동력을 발생시키는 클로저바디(3)와 상기 클로저바디(3)로부터 인출되어 도어(4)와 결합 되는 작동로드(5)로 구성된다.As shown in FIG. 7, the door closer 1 is mounted on the door frame 2 and is drawn out from the closure body 3 and the closure body 3 to generate an operating force by incorporating hydraulic pressure or a spring. It consists of a working rod (5) coupled with.

상기와 같이 구성되는 도어클로저는 화재발생시에는 자동폐쇄장치와 연결되어 개방된 방화문을 자동으로 닫아서 폐쇄시키거나, 가정의 현관문과 같은 경우에는 이용자가 도어를 개방한 후 별도로 닫기 위한 동작을 취하지 않더라도 클로저바 디 내부에 설치되어 발생시키는 작동력을 전달받은 작동로드가 도어(방화문 또는 현관문 이하 도어라 한다.)를 닫아주는 작동을 수행하는 것이다.The door closer configured as described above is connected to the automatic closing device in case of fire and automatically closes and closes the open fire door, or in the case of the front door of a home, the door closer is closed even if the user does not take an action to close the door after opening it. The operating rod, which receives the operating force generated by the inside of the body, performs the operation of closing the door (called the door below the fire door or the front door).

상기와 같이 도어를 개방한 상태에서 닫혀 질 때 또는 화재 등이 발생하여 자동으로 페쇄 시킬 때에는 급기댐퍼에 의하여 방연풍속과 차압이 발생하여 도어 방향으로 전도될 경우에는 도어가 도어클로저에 의하여 정상적으로 닫힘 상태를 유지하지 못하고, 전도되는 압력에 의하여 닫힘 직전에서 정지하게 되는 현상이 발생하게 된다.As described above, when the door is closed with the door open or automatically shut off due to a fire or other fire, the door is normally closed by the door closer when the wind speed and the differential pressure are generated by the air supply damper and conducted in the direction of the door. It is not maintained, the phenomenon occurs that stops just before closing by the pressure being conducted.

이와 같이 도어가 완전하게 닫히지 못하게 될 경우에는 재연구역 또는 방화구역 방화문을 이용자가 인위적으로 도어를 당기거나 밀어서 견고한 닫힘 상태를 유지하여야 하므로 번거로움이 발생하게 된다.In this way, when the door is not completely closed, the repetition zone or fire zone fire door is a user to artificially pull or push the door to maintain a solid closed state is a hassle occurs.

상기와 같이 방화문의 닫힘 상태를 견고하게 유지하지 못할 경우에는 제연구역 또는 안전구역을 정상적으로 형성하지 못하고, 화염과 유독가스의 유출로 인하여 재산상의 손실은 물론 인명사고를 방지하고자 하는 목적을 달성할 수 없게 된다.If it is not possible to maintain the closed state of the fire door firmly as described above, it is impossible to form a smoke control area or a safety zone normally, and the purpose of preventing property loss as well as personal injury due to the outflow of flame and toxic gas can be achieved. There will be no.

특히, 방화문 또는 현관 도어의 크기가 증대되면서 일반적인 도어클로저만을 이용하여 닫힘 상태를 유지하고자 할 경우에는 실내에서 도어 방향으로 전도되는 압력이 없는 상태라 하더라도 도어클로저 자체의 작동력이 미약하여 견고한 닫힘 상태를 유지하지 못하게 되는 등 여러 문제점이 발생하고 있는 실정이다.In particular, when the size of the fire door or the front door is increased and the door door is to be kept closed using only a normal door closer, the door closer itself is weakly operated even though there is no pressure conducted in the direction of the door from the room. There are many problems, such as not being able to maintain.

이에 본 발명에서는 상기와 같은 문제점들을 해결하기 위하여 발명한 것으로서 도어클로저의 저면에 장착되어 작동로드를 움직이는 작동축에 도어가 닫히는 최종시점에 닫힘에 필요한 폐쇄력을 증강시켜 전달하여 완전한 닫힘 상태를 유지하도록 하는 도어클로저용 폐쇄력 증강장치에 있어서;Therefore, the present invention has been invented in order to solve the above problems, it is mounted on the bottom surface of the door closer to the operating shaft to move the operating rod to increase the closing force required for closing at the closing time of the door to maintain a fully closed state A closing force enhancer for a door closer to be provided;

It may be configured in the form of a note.

상기와 같은 본 발명의 기술이 적용된 도어클로저용 폐쇄력 증강장치(100)의 작용에 대하여 살펴보면 다음과 같다.Looking at the action of the closing force enhancer 100 for the door closer to which the technology of the present invention is applied as described above.

초기상태를 도어가 닫혀있는 상태로 보았을 때에는 폐쇄력발생자(108)를 구성하는 스프링(113)은 최대한 팽창된 상태에 있고 이로 인하여 폐쇄력증강자(109)를 구성하는 1레버(115)와 2레버(116)의 힌지(P1,P2)는 최대닫힘위치(A1, B1)에 있고 이로 인하여 2레버(116)의 후미에 구비되는 가압자(117)는 도어클로저(101)의 작동축(103)에 결합 되는 작동자(107)를 구성하는 캠(110)의 연접턱(111)을 밀어 닫힘위치로 밀어주게 되는 형태가 된다.When the initial state is viewed as the door is closed, the spring 113 constituting the closing force generator 108 is in the expanded state as much as possible, and thus, the first lever 115 constituting the closing force enhancer 109 and Hinge (P1, P2) of the two lever 116 is in the maximum closed position (A1, B1), so that the pressurizer 117 provided at the rear of the two lever 116 is the operating shaft 103 of the door closer 101 ) Is pushed to the closed position by pushing the connecting jaw 111 of the cam 110 constituting the operator 107 is coupled to.

상기와 같이 닫힘 상태에서 도어를 개방하면, 도어클로저(101)의 작동축(103)이 회전하면서 이와 결합 된 캠(110)이 회전하면서 연접턱(111)에 의하여 가압자(117)는 후퇴하면서 캠(110)의 최대외경(R1)과 연접된다.When the door is opened in the closed state as described above, while the operating shaft 103 of the door closer 101 is rotated while the cam 110 coupled thereto rotates and the pressurizer 117 is retracted by the connecting jaw 111. It is connected with the largest outer diameter R1 of the cam 110.

이때에는 2레버(116)와 1레버(115)의 힌지(P1,P2)는 가압자(117)의 이동에 따라 근접닫힘위치(A2,B2)에 있고, 스프링(113)은 수축된 상태에 있게 되며, 이러한 상태에서 가압자(117)가 도어의 최대 개방시까지 캠(110)의 최대외경(R1)에 위치하고 있이므로 도어클로저(101)의 작동에 영향을 미치지 않게 된다.At this time, the hinges P1 and P2 of the 2 lever 116 and the 1 lever 115 are in the close closing positions A2 and B2 as the pressurizer 117 moves, and the spring 113 is in a contracted state. In this state, the pressurizer 117 is located at the maximum outer diameter R1 of the cam 110 until the maximum opening of the door does not affect the operation of the door closer 101.

이러한 상태에서 도어를 닫게 되면, 도어클로저(101)에 의하여 도어가 근접닫힘위치(A2,B2) 까지 도어를 닫을 동안에는 폐쇄력 증강장치(100)는 작동하지 않게 되는 데, 이는 작동축(103)과 연결되어 회전하는 캠(110)의 최대외경(R1)에 가압자(117)가 연접한 상태에 있기 때문이다.When the door is closed in such a state, the closing force enhancer 100 is not operated while the door is closed by the door closer 101 to the close closing positions A2 and B2, which is an operation shaft 103. This is because the pressurizer 117 is in contact with the maximum outer diameter R1 of the cam 110 which is connected to and rotated.

도어클로저(101)에 의하여 가압자(117)가 근접닫힘위치(A2,B2)에 다달으면 캠(110)에 형성되는 절개부(R)의 연접턱(111)과 밀착되고, 이와 동시에 수축되었던 스프링(113)이 팽창되면서 미는 힘이 페쇄력증강자(109)를 구성하는 1,2레버(115,116)를 통하여 전달되어 가압자(117)를 당기게 되고, 이 힘이 캠(110)으로 전달되고 결국에는 캠(110)과 결합 된 도어클로저(101)의 작동축(103)을 회전시켜 최대닫힘위치(A1, B1)에 있도록 함으로서 도어는 견고한 닫힘 상태를 유지할 수 있게 되는 것이다.When the pressurizer 117 reaches the close-close positions A2 and B2 by the door closer 101, the pressurizer 117 is brought into close contact with the junction 111 of the cutout R formed in the cam 110, and simultaneously contracted. As the spring 113 is expanded, the pushing force is transmitted through the first and second levers 115 and 116 constituting the closing force enhancer 109 to pull the pressurizer 117, which is transmitted to the cam 110. Eventually, by rotating the operating shaft 103 of the door closer 101 combined with the cam 110 to be in the maximum closed position (A1, B1) will be able to maintain a solid closed state.

상기와 같은 본 발명은 폐쇄력발생자(108)의 스프링(112)이 발생시키는 힘을 폐쇄력증강자(109)의 1,2레버(115,116)로 전달되어 그 힘이 증폭된 상태에서 가압자(117)를 통하여 작동자(107)로 전달되어 작동축(103)에 힘을 보태어 도어를 완전하게 닫을 수 있게 된다.The present invention as described above is the force generated by the spring 112 of the closing force generator 108 is transmitted to the first and second levers 115 and 116 of the closing force enhancer 109, the pressurizer in a state in which the force is amplified It is transmitted to the operator 107 through 117 to apply a force to the operating shaft 103 to be able to close the door completely.

이 과정에서 폐쇄력증강자(109)를 구성하는 1레버(115)와 장치바디(105)를 연결하는 힌지(P)와 1레버(115)와 2레버(116)를 연결하는 힌지(P1)와의 거리(L)는, 1레버(115)와 2레버(116)의 선측을 연결하는 힌지(P1)와 2레버(116)의 후단에 가압자(117)를 연결하는 힌지(P2)와의 거리(L1)보다 짧게 함으로서 지레대의 원리에 의하여 힘의 증대를 통하여 전달 가능하게 되는 것이다.In this process, the hinge P connecting the first lever 115 and the device body 105 constituting the closing force enhancer 109 and the hinge P1 connecting the first lever 115 and the second lever 116 are provided. The distance L is a distance between the hinge P1 connecting the first side of the first lever 115 and the second lever 116 and the hinge P2 connecting the pressurizer 117 to the rear end of the second lever 116. By making it shorter than (L1), it becomes possible to transmit through the increase of force by the principle of the lever.

또한 본 발명에서는 도어의 크기가 변화되거나 내부에서의 압력이 증가 될 경우에는 그에 대응하여 폐쇄력발생자(108)의 압력을 증대시켜 극복할 수 있게 되는 데, 이를 살펴보면,In addition, in the present invention, when the size of the door is changed or the pressure inside increases, it is possible to overcome by increasing the pressure of the closing force generator 108 in response thereto.

스프링(113)을 내장한 실린더(112)를 마감하고 있는 조절캡(114)을 정방향과 역방향으로 회전시켜 스프링(113)의 압축 정도를 조절함으로서 폐쇄력의 발생상태를 가감할 수 있게 되고, 이와 같이 가감된 폐쇄력은 폐쇄력증강자(109)에 의하여 증폭되기 때문에 조절캡(114)의 미세한 조절로도 충분하게 증대된 힘을 얻을 수 있는 것은 물론, 조절범위가 넓기 때문에 광역대의 적용이 가능한 장점을 가지게 되는 것이다.By adjusting the compression degree of the spring 113 by rotating the control cap 114 closing the cylinder 112 with the built-in spring 113 in the forward and reverse directions, it is possible to add or subtract a state of closing force, As the closed force added or subtracted is amplified by the closing force enhancer 109, a finely adjusted force can be obtained even by fine adjustment of the adjusting cap 114, and a wide range of control is possible because of the wide adjustment range. You will have an advantage.

이러한 본 발명은 도어 내부에서 도어 방향으로 발생하는 압력이나 도어 크기의 증대로 인한 도어클로저의 작동력이 일부 상실되더라도 도어가 거의 닫혀 질 때 완벽한 닫힘 상태를 유지할 수 있는 힘을 도어클로저에 부여함으로서 도어의 작 동력을 향상시키고, 방화문의 경우 안전지대를 확보할 수 있는 등 다양한 장점을 가지는 발명이다.The present invention provides the door closer by giving the door closer a force to maintain a completely closed state even when the door is almost closed even if the operating force of the door closer due to the increase in the door size or the pressure generated in the door direction is lost. It is an invention having various advantages, such as improving operation power and securing a safety zone in the case of a fire door.
