Description

도어 클로저 가드{Door Closer Guard}Door Closer Guard

본 발명은 도어 클로저 가드에 관련되며, 보다 상세하게는 도어의 갑작스런 닫힘으로 인한 안전사고를 방지하는 도어 클로저 가드에 관한 것이다.The present invention relates to a door closer guard, and more particularly to a door closer guard for preventing a safety accident due to the sudden closing of the door.

통상적으로 도어는 냉난방에 따른 에너지 효율 및 편의성을 높이기 위해 자동으로 닫이도록 도어클로저를 설치하는바, 이때 도어클로저는 스프링과 유압을 이용하여 도어의 개방력을 압축후 복원력에 의해 닫히도록 구성된다.Typically, the door is installed to close the door automatically to increase the energy efficiency and convenience according to the heating and cooling, the door closer is configured to close the opening force of the door by the restoring force after compression using a spring and hydraulic pressure.

하지만, 도어가 닫힐시 충격으로 인해 소음이 심하게 발생됨에 따라 도서관, 병원, 연구소를 포함하는 정숙이 필요한 위치에 적용이 불가능하고, 도어클로저가 없거나 고장난 곳에서는 자칫 도어와 문틀사이에 영유아의 손가락이 끼여 안전사고로 이어지는 사례가 허다하게 발생되고 있다.However, when the door is closed, the noise is severely generated, so it is impossible to apply it in a location requiring quietness, including libraries, hospitals, and laboratories.In the absence or failure of the door closer, infants' fingers are caught between the door and the door frame. There are many cases that lead to safety accidents.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 발명은 도어 클로저 가드에 관련되며, 이때 도어 클로저는 구조 및 설치가 간단하고, 장기간 반복사용에 따른 작동불량 및 잔고장을 방지하기 위해 마찰드럼(10), 작동편(20), 원심브레이크부(30)를 포함하여 주요구성으로 이루어진다.The present invention relates to a door closer guard, in which the door closer is simple in structure and installation, in order to prevent malfunction and residual trouble caused by repeated use for a long time, the friction drum 10, the operating piece 20, the centrifugal brake unit ( It consists of major components, including 30).

본 발명에 따른 마찰드럼(10)은 일측에 고정판(12)이 구비되고, 내주면에 링기어(14)가 형성된다. 마찰드럼(10)은 양단이 개방된 원통형의 관재형상으로 형성되고, 일단에 고정판(12)이 돌출형성되어 문틀 또는 도어(후술하는 작동편(20)의 연결대(22)가 도어상에 고정시 고정판(12)은 문틀상에 고정되고, 연결대(22)가 문틀상에 고정시 고정판(12)은 도어상에 설치됨)상에 고정된다.The friction drum 10 according to the present invention is provided with a fixed plate 12 on one side, the ring gear 14 is formed on the inner peripheral surface. The friction drum 10 is formed in the shape of a cylindrical tube with both ends open, and the fixing plate 12 is protruded at one end to secure the door frame or door (the connecting table 22 of the operation piece 20 to be described later) fixed on the door. The fixing plate 12 is fixed on the door frame, and the fixing plate 12 is fixed on the door when the connecting rod 22 is fixed on the door frame.

이때 마찰드럼(10)은 후술하는 원심블레이크부(30)의 마찰편(38)과 마찰되어 브레이킹되도록 내주면이 마찰면으로 형성되고, 상측 또는 하측 내주면에 링기어(14)가 형성되어 후술하는 유성기어(32)와 치합된다.At this time, the friction drum 10 has an inner circumferential surface formed as a friction surface so as to be rubbed with the friction piece 38 of the centrifugal brake portion 30 to be described later, and a ring gear 14 is formed on the upper or lower inner circumferential surface, so as to be described later. It meshes with the gear 32.

또한, 본 발명에 따른 작동편(20)은 마찰드럼(10)을 중심으로 선회되도록 설치되고, 일단에 연결대(22)가 구비된다. 작동편(20)은 마찰드럼(10)의 양단을 마감하도록 한 쌍으로 구비되고, 후술하는 원심브레이크부(30)와 함께 마찰드럼(10)을 축으로 선회되도록 구비된다.In addition, the operating piece 20 according to the present invention is installed to pivot about the friction drum 10, and one end 22 is provided at one end. The operation piece 20 is provided in pair to finish both ends of the friction drum 10, and is provided to pivot the friction drum 10 along the centrifugal brake portion 30 to be described later.

그리고, 작동편(20)은 일단에 연결대(22)가 돌출되어 문틀 또는 도어상에 설치(상기 고정판(12)이 문틀상에 고정시 작동편(20)의 연결대(22)는 도어상에 고정되고, 고정판(12)이 도어상에 설치시에는 연결대(22)가 문틀상에 고정 됨)되는바, 이때 연결대(22)는 보조 연결대(22a)와 링크결합에 의해 연장되어 도어 또는 문틀의 개폐작동에 따른 선회작동이 유연하게 이루어지도록 형성된다. (도 1에서는 연결대가 도어에 설치된 상태를 도시함)And, the operating piece 20 is installed on the door frame or the door protruding the connecting rod 22 at one end (when the fixing plate 12 is fixed on the door frame, the connecting table 22 of the operating piece 20 is fixed on the door). When the fixing plate 12 is installed on the door, the connecting table 22 is fixed on the door frame), wherein the connecting table 22 is extended by the link coupling with the auxiliary connecting table 22a to open or close the door or the door frame. It is formed to make the swinging operation flexible according to the operation. (Figure 1 shows the connecting rod installed in the door)

또한, 본 발명에 따른 원심브레이크부(30)는 작동편(20)상에 설치되고, 유성기어(32)를 통하여 링기어(14)와 치합되어 증속회전되도록 축기어(34a)가 구비되는 회전플레이트(34)와, 회전플레이트(34) 상부에서 일단이 축봉(36)으로 연결되고, 회전시 원심력에 의해 확장되어 마찰드럼(10) 내주면과 마찰되는 마찰편(38)이 구비된다.In addition, the centrifugal brake unit 30 according to the present invention is installed on the operating piece 20, and is rotated with the shaft gear 34a so as to be engaged with the ring gear 14 through the planetary gear 32 to increase the speed. One end of the plate 34 and the rotating plate 34 is connected to the shaft bar 36, and a friction piece 38 is expanded by centrifugal force during rotation to rub against the inner circumferential surface of the friction drum 10.

여기서 회전플레이트(34)는 작동편(20)의 중심에 구비되는 지지축상에 회전되도록 설치되면서 마찰드럼(10) 내측에 수용되고, 하부에 축기어(34a)와 상부에 마찰편(38)이 구비된다. 여기서 마찰편(38)은 아치형으로 형성되어 서로 대향하는 위치에 한 쌍으로 배치되고, 일단부가 축봉(36)을 통하여 회전플레이트(34)상에서 선회되도록 설치된다. 그리고 축기어(34a)는 도 4처럼 유성기어(32)를 통하여 링기어(14)와 치합되고, 이때 유성기어(32)는 작동편(20)상에서 회전되도록 설치된다.Here, the rotation plate 34 is installed to rotate on the support shaft provided in the center of the operation piece 20 is accommodated inside the friction drum 10, the lower shaft gear 34a and the friction piece 38 on the upper It is provided. Here, the friction pieces 38 are formed in an arcuate shape and are arranged in pairs at positions opposite to each other, and one end portion thereof is pivoted on the rotation plate 34 through the shaft bar 36. And the shaft gear 34a is engaged with the ring gear 14 through the planetary gear 32, as shown in Figure 4, wherein the planetary gear 32 is installed to rotate on the operating piece (20).

이에 도어의 개방 또는 폐쇄작동에 의해 작동편(20)이 유성기어(32)와 함께 선회시 유성기어(32)가 링기어(14)를 치합되어 공전운동 중에 자전운동력이 발생되어 회전력이 발생되고, 이때 유성기어(32)의 자전 회전력은 축기어(34a)를 통하여 회전플레이트(34)로 전달된다. 이어서 회전플레이트(34)가 유성기어(32)에 의해 회전되면 원심력에 의해 도 5와 같이 마찰편(38)이 축봉(36)을 중심으로 선회되어 확장되면서 마찰드럼(10)의 내주면과 마찰되어 브레이킹작동을 수행하므로 도어의 닫힘 또는 열림속도가 저속으로 일정하게 유지된다.Accordingly, when the operating piece 20 swings together with the planetary gear 32 by the opening or closing of the door, the planetary gear 32 engages the ring gear 14 to generate a rotational force during an orbiting motion, thereby generating rotational force. In this case, the rotational rotational force of the planetary gear 32 is transmitted to the rotation plate 34 through the shaft gear 34a. Subsequently, when the rotation plate 34 is rotated by the planetary gear 32, the friction piece 38 is pivoted about the shaft rod 36 and expanded by centrifugal force to be rubbed with the inner circumferential surface of the friction drum 10 as shown in FIG. 5. As the braking operation is performed, the closing or opening speed of the door is kept constant at low speed.

이때, 도어의 닫힘 또는 열림 작동에 의해 작동편(20)의 선회속도가 빨라 질수록 마찰편(38)의 원심력이 극대화되면서 마찰력이 증가되므로, 작동편(20)의 선회속도는 마찰편(38)의 원심력과 마찰력에 비례하게 되어 문닫힘 속도가 저속으로 유지된다. At this time, since the rotational speed of the operating piece 20 is increased by the closing or opening of the door, the frictional force is increased while maximizing the centrifugal force of the friction piece 38. It is proportional to the centrifugal force and frictional force of) and the door closing speed is kept at a low speed.

또한, 상기 마찰편(38)은 마찰드럼(10)과 대응하는 외주면에 마찰패드(38a)가 탈부착가능하게 구비된다. 마찰패드(38a)는 마찰드럼(10)과 직접적으로 마찰되어 마찰력이 발생되는 부분으로서, 도 2처럼 마찰편(38)상에 끼움결합되거나 볼트체결되어 탈부착가능하게 구비된다. 이에 장기간 사용으로 마찰력이 저하되어 도어의 닫힘속도가 저속으로 유지되지 못할 경우, 마찰패드(38a)의 부분적인 교체작업으로 마찰력이 간단하게 복원되므로 유지보수가 간편한 이점이 있다.In addition, the friction piece 38 is provided with a detachable friction pad 38a on an outer circumferential surface corresponding to the friction drum 10. The friction pad 38a is a portion in which friction force is generated by directly rubbing with the friction drum 10, and the friction pad 38a is detachably fitted or bolted onto the friction piece 38 as shown in FIG. 2. Therefore, when the frictional force is degraded due to long-term use and the closing speed of the door cannot be maintained at a low speed, the frictional force is simply restored by partial replacement of the friction pad 38a.

또한, 상기 작동편(20)는 토션스프링(24)에 의해 선회후 자동 복귀되도록 구비된다. 토션스프링(24)은 도 3처럼 별도의 스프링케이스(24a)상에 수용된 상태로 어느 일측 작동편(20)상에 설치되고, 도어의 개방에 따른 작동편(20)의 선회방향과 반대방향으로 반발력이 작용하여 도어가 자동으로 닫히는 자동 도어 클로저역활을 수행한다.In addition, the operation piece 20 is provided to automatically return after the turning by the torsion spring (24). The torsion spring 24 is installed on one side of the operating piece 20 in a state of being accommodated on a separate spring case 24a as shown in FIG. 3, and in a direction opposite to the turning direction of the operating piece 20 according to the opening of the door. The reaction force acts as an automatic door closer, which automatically closes the door.

이때, 스프링케이스(24a)는 볼트를 통하여 작동편(20)상에 간편하게 탈부착되도록 설치됨에 따라 개방된 도어가 자동으로 닫히는 자동 도어 클로저로의 구조변경이 용이한 이점이 있다.At this time, the spring case 24a is easily installed on the operation piece 20 through a bolt, and thus, the structure of the spring door 24a can be easily changed to an automatic door closer in which the open door is automatically closed.

한편, 마찰드럼(10)과 작동편(20)이 경접형태로 접철되도록 형성됨에 따라 도어를 설치시 종래에 경첩을 배재하고 도어를 마찰드럼(10)과 작동편(20)에 의해 지지되어 개폐되도록 설치하는 구성도 가능하다.On the other hand, since the friction drum 10 and the operating piece 20 are formed to be folded in a hinged manner, when the door is installed, the hinge is conventionally disposed and the door is supported by the friction drum 10 and the operating piece 20 to open and close. It is also possible to install the configuration.
