본 발명은 도어의 안정된 폐쇄가 가능한 도어클로저에 관한 것이며, 더욱 상세하게는 회동축의 정방향 회동력이 약화된 시점 즉, 도어가 문틀에 진입하여 닫히는 시점에 회동축에 외력을 제공하여서 도어의 안정된 폐쇄상태를 확보할 수 있도록 한 도어의 안정된 폐쇄가 가능한 도어클로저에 관한 것이다.The present invention relates to a door closer capable of a stable closing of the door, and more particularly, to stabilize the door by providing an external force to the rotating shaft when the forward rotational force of the rotating shaft is weakened, that is, when the door enters and closes the door frame. The present invention relates to a door closer capable of stable closing of a door to secure a closed state.

일반적으로, 도어와 문틀에는 도어 클로저가 설치되어, 상기 도어클로저의 폐쇄력에 의해 도어가 자동으로 폐쇄되도록 하고 있다.In general, the door and the door frame is provided with a door closer, so that the door is automatically closed by the closing force of the door closer.

상기 도어 클로저는 일반적으로 도어가 개방되어 회동축이 역방향으로 선회한 상태에서는 강한 폐쇄력(정방향 회동력)을 가지며, 회동축이 정방향으로 선회하여 도어가 점차 폐쇄되면 폐쇄력(정방향 회동력)은 점차 약화 내지 소실된다.The door closer generally has a strong closing force (forward rotational force) when the door is open and the rotating shaft is rotated in the reverse direction, and the closing force (forward rotational force) is obtained when the door is gradually closed due to the rotation of the rotating shaft in the forward direction. Gradually weakening or disappearing.

그러나, 도어의 폐쇄과정에서 가장 큰 폐쇄력이 요구되는 시점은 도어가 문틀에 진입하는 시점이지만, 이때 도어 클로저의 회동축의 폐쇄력 즉, 정방향 회동력이 가장 약화된 시점이다.However, the time when the largest closing force is required in the closing process of the door is the time when the door enters the door frame, but the closing force of the rotation shaft of the door closer, that is, the forward rotational force is the weakest point.

즉, 도어가 문틀에 진입하여 잠기는 시점에도 안정된 폐쇄력이 제공되어야 하지만, 도어 클로저의 회동축은 그 특성상 이때 가장 약한 폐쇄력을 도어에 제공하게 되는 것이다.That is, a stable closing force should be provided even when the door enters and locks the door frame, but the rotational shaft of the door closer provides the weakest closing force to the door at this time.

따라서, 도어 클로저의 폐쇄력에 의해 도어가 완전히 닫히지 아니하는 현상이 종종 발생되어, 사용자가 직접 도어를 밀어서 도어를 폐쇄하여야 하는 번거로움이 발생기도 한다.Therefore, the phenomenon in which the door is not completely closed by the closing force of the door closer is often generated, and the inconvenience of having to close the door by pushing the door directly is also generated.

특히, 이러한 현상은 방화용 도어에서 더욱 심화되어, 안정된 재연구역의 확보에 장애를 초래할 수도 있다.In particular, this phenomenon may be further exacerbated in the fire door, which may cause an obstacle in securing a stable regeneration zone.

이를 부연하자면, 방화용 도어는 도어 스토퍼의 구속에 의해 평상시에는 개방된 상태를 유지하다가 화염신호를 감지하면 도어 스토퍼의 구속이 해제되어, 도어 클로저의 작용에 의해 폐쇄되도록 구성된다.In detail, the fire door is normally maintained by the lock of the door stopper, and when the flame signal is detected, the lock of the door stopper is released and is closed by the action of the door closer.

그런데, 상기 도어 클로저의 폐쇄력이 약화되어 도어가 완전히 닫히지 아니하면 제연구역의 안정된 형성이 어려워서, 유독가스가 전층으로 확산되어 비상통로를 안정되게 확보할 수 없는 문제점을 가지게 되고, 이로 인해 안전사고가 발생될 수도 있다.However, when the closing force of the door closer is weakened and the door is not completely closed, it is difficult to stably form a smoke control area, and thus toxic gas is diffused to all floors, so that an emergency passage cannot be stably secured, resulting in a safety accident. May be generated.

따라서, 당분야에서는 도어를 안정되게 폐쇄시킬 수 있는 도어 클로저의 개발 및 보급이 시급히 요구되고 있다.Therefore, there is an urgent need in the art for the development and dissemination of door closers capable of stably closing doors.

상기한 문제점을 해소하기 위해 안출된 본 발명의 목적은, 본체에 가압홈이 형성된 작동기어와 탄지부재를 각각 배설하여, 회동축의 폐쇄력(정방향 회전력)이 약화된 시점에 탄지부재의 탄발력이 회동축에 제공되도록 구성하여, 도어의 안정된 폐쇄가 이룩되도록 한 도어클로저를 제공함에 있다.An object of the present invention devised to solve the above problems, the operation gear and the support member formed with a pressure groove formed in the main body, respectively, so that the closing force of the rotation shaft (forward rotational force) the elastic force of the support member at the time of weakening It is provided to this rotating shaft, and to provide a door closer to achieve a stable closing of the door.

한편, 본 실시예에 따른 도어 클로저(1, 1')를 통한 도어(100)의 폐쇄과정은, 도 4 내지 도 5에서 보는 바와 같이 최초 도어(100)가 개방되어 회동축(11)이 역방향으로 절환된 상태에서 회동축(11)이 정방향으로 회전하면, 선회암(12)과 고정 브라켓(14)을 통해 문틀(110)과 링크구조를 형성한 절첩암(13)은 절첩되어서, 도어(100)는 서서히 정방향으로 절환되어 폐쇄된다.Meanwhile, in the closing process of the door 100 through the door closers 1 and 1 'according to the present embodiment, as shown in FIGS. 4 to 5, the first door 100 is opened so that the pivot shaft 11 is reversed. When the rotating shaft 11 is rotated in the forward direction in the state of switching to, the folding arm 13 forming the link structure with the door frame 110 through the pivoting arm 12 and the fixing bracket 14 is folded, the door ( 100 is gradually switched to the forward direction and closed.

이 과정 중에는, 도 4(a)와 도 5(a)와 같이 일편에 설치된 탄지부재(30, 40)가 회동축(11)에 축 설치된 작동기어(22)의 외경면(22)을 탄지하므로, 작동기어(20)는 실질적으로 회동축(11) 자체의 정방향 회전력에 의해 회전한다.During this process, since the support members 30 and 40 provided on one side as shown in Figs. 4 (a) and 5 (a) support the outer diameter surface 22 of the operating gear 22 provided on the pivot shaft 11. , The operating gear 20 rotates substantially by the forward rotational force of the rotation shaft 11 itself.

그러나, 도 4(b)와 도 5(b)와 같이 회동축(11)의 자체 회전력에 의해 도어(100)가 서서히 더 닫혀져 도어(100)가 문틀(110)에 진입하는 순간, 즉, 회동축(11) 자체의 정방향 회전력이 약화된 시점에는 탄지부재(30, 40)와 작동기어(20)의 가압홈(22a)은 대향되게 위치한다.However, as shown in FIGS. 4B and 5B, the door 100 is gradually closed by the self-rotating force of the pivot shaft 11, so that the door 100 enters the door frame 110. When the forward rotational force of the coaxial 11 itself is weakened, the presser members 30 and 40 and the pressing grooves 22a of the operating gear 20 are positioned to face each other.

따라서, 압축된 탄지부재(30, 40)는 작동기어(20)의 가압홈(22a)을 견착하여 탄지하게 되고, 따라서, 작동기어(20)를 통해 탄지부재의 탄발력을 인가받은 회동축(11)은 정방향으로 신속히 회전하여서, 도어(100)의 안정적인 폐쇄를 구현하게 되는 것이다.Therefore, the compressed support members 30 and 40 adhere to the pressing grooves 22a of the operating gear 20 and are hardened. Accordingly, the rotation shafts to which the elastic force of the support member is applied through the operating gear 20 ( 11) is to quickly rotate in the forward direction, to achieve a stable closing of the door (100).

전술한 바와 같이 본 발명에서는 본체에 가압홈이 형성된 작동기어와 탄지부재를 각각 배설하여, 회동축의 회전력이 약화된 시점에 탄지부재의 탄발력이 회동축에 제공되도록 함으로써, 도어의 안정적인 폐쇄를 도모하는 도어 클로저를 제안하고 있다.As described above, in the present invention, the actuating gear and the support member having the press groove formed on the main body are respectively disposed so that the resilience of the support member is provided to the rotation shaft at a time when the rotational force of the rotation shaft is weakened, thereby ensuring stable closing of the door. We propose door closer to plan.

본 발명에 부가하고 있는 탄지부재와 작동기어는, 구조가 간단하여 저렴한 비용으로 생산이 가능하고, 또 종래의 도어 클로저에 구조적인 변경없이 적용할 수 있는 이점을 가진다.The support member and the operation gear added to the present invention have a simple structure and can be produced at low cost, and can be applied to a conventional door closer without a structural change.

이러한 도어 클로저가 상용화되어 보급되면, 도어의 안정적인 폐쇄상태가 확보될 수 있어 사용상의 편의가 도모되고, 특히 방화용 도어에 설치할 경우 재연구역을 안정되게 확보할 수 있다.When such a door closer is commercially available and distributed, a stable closed state of the door can be secured, thereby facilitating convenience of use, and in particular, when the door closer is installed in a fire door, the regeneration zone can be secured.
