본 고안은 도어를 개폐함에 있어서, 도어를 열때는 수동으로하고 닫을때는 자동적으로 닫힐수 있도록 한 도어 개폐용 경첩에 관한 것이다.The present invention relates to a door opening and closing hinge that can be opened and closed manually when opening and closing the door.

종래의 도어 개폐장치를 보면, 공기 또는 유압식의 실린더를 도어 상부에 설치하여 열려진 도어가 자동적으로 닫히도록 한 것이 있었고, 또한 경첩을 나사식으로 형성하여 나사의 경사도에 따라 도어가 닫힐수 있도록 한 것이 있었으며, 또한 코일스프링을 경첩의 핀에 권회하여 이의 복원력으로 도어가 닫힐수 있도록 한 것이 있었다.According to the conventional door opening and closing device, an air or hydraulic cylinder was installed at the upper part of the door to open the door closed automatically, and a hinge was formed in a screw type so that the door could be closed according to the inclination of the screw. There was also a coil spring wound around the hinge pin to allow the door to close with its restoring force.

그러나, 전자의 것은 실린더의 밀폐를 잘해야 하는 문제점과 더불어 구조가 복잡하고 설치공간을 많이 차지하게 되는 결점이 있었으며, 후자의 것들은 제작이 매우 까다롭고 경사도가 작을 경우 작동이 제대로 되지 않는 점등의 결점을 지니고 있었으며, 또한 문을 닫을때 가속도가 생기거나 스프링의 탄력이 문의 회전방향으로 이루어 지게되어 많은 충격을 동반하게 되는 점등의 문제점이 있었다.However, the former has the drawback that the cylinder needs to be well sealed and the structure is complicated and occupies a lot of installation space. The latter has the drawback of lighting that is very difficult to manufacture and does not work properly when the slope is small. Also, when the door is closed, the acceleration occurs or the elasticity of the spring is made in the direction of rotation of the door, there was a problem of lighting that is accompanied by a lot of impact.

본 고안 종래의 결점을 해소하기 위하여 안출한 것으로, 도어의 닫힘이 자동적으로 닫힘과 동시에 닫힘상태가 충격없이 매우 조용하고, 설치공간이 적게 소요되는 도어개폐용 경첩을 제공하는데 그 목적이 있는 것이다.The present invention has been made in order to solve the drawbacks of the prior art, and the purpose of the door is to provide a hinge for the door opening and closing, the door is automatically closed and at the same time the closed state is very quiet and less installation space.

즉, 본 고안은 상기의 목적을 달성하기 위하여 절개부를 형성한 판스프링을 경첩의 양쪽 고정편에 착탈가능으로 설치하여 이 판스프링이 고정편을 탄압하여 탄성을 부여토록 구성된 것을 특징으로 하는 것이다.That is, the present invention is characterized in that the leaf spring is formed to be detachably installed on both fixing pieces of the hinge in order to achieve the above object, the leaf spring is configured to press the fixing piece to give elasticity.

또한 본 고안은 상기 경첩의 양쪽 고정 개폐상태 조정용 절곡부를 형성하여서 구성된 것을 특징으로 하는 것이다.In addition, the present invention is characterized in that formed by forming the bent portion for adjusting both the fixed opening and closing state of the hinge.

또한, 본 고안은 판스프링의 절개부 일단에 외향 확개부를 형성하여서 구성된 것을 특징으로 하는 것이다.In addition, the present invention is characterized in that it is configured by forming an outwardly extending portion at one end of the cut portion of the leaf spring.

이와같이 된 본 고안은 고정편에 판스프링을 외향확개부를 이용하여 용이하게 삽입시키고 도어와 고정벽체에 고정편을 설치하여서 사용하는 것으로, 도어 개방시 판스프링의 탄력으로 자동적으로 복원됨과 동시에 도어개방각도가 크면 클수록 복원시의 판스프링의 탄력은 그 작용점이 핀의 중심과 근접하게 되어 도어측과 벽체측의 탄력이 상호 상쇄되므로 가속도에 의한 충격없이 조용히 닫히게 되는 것이다.In this way, the present invention can be easily inserted into the fixing piece by using the outward expansion portion, and the fixing piece is installed on the door and the fixing wall, and the plate spring is automatically restored to the elasticity of the leaf spring when the door is opened and at the same time the door opening angle is used. The larger the elasticity of the leaf spring at the time of restoration becomes closer to the center of the pin, so that the elasticity of the door side and the wall side cancels each other so that it closes quietly without the impact of acceleration.

따라서 보 고안은 간단한 구조로 설치와 사용이 간편하고, 닫힘과 열림을 반자동에 의한 방식으로 충격없이 원할하게 작동하는 등이 이점이 있는 것이다.Therefore, the design is easy to install and use with a simple structure, there is an advantage that the smooth operation without impact in a semi-automatic way of closing and opening.

이하에서 본 고안의 실시예를 첨부도면을 통하여 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

개폐상태 조정용 절곡부(3)(4)와 걸림턱(6)을 형성한 고정편(1)(2)의 외측면에 합성수지재 걸림편(5)을 각각 부착시키고, 상기 각 고정편(1)(2) 사이를 핀(7)으로 결합시키며, 외형확개부(10)와 절개부(9)를 형성한 판스프링(8)을 상기 걸림편(5)에 걸리도록 상부에서 삽입시켜서 도어(11) 개방시 고정편(1)(2)의 확개각도가 클수록 판스프링(8)의 탄력작용점이 핀(7)의 중심쪽으로 접근하여 판스프링(7)의 복원력에 의한 가속도륵 상쇄시켜서 충격없이 자동적으로 닫히도록 구성된 것이다.Attaching the synthetic resin locking piece (5) to the outer surface of the fixing piece (1) (2) formed the bent portion (3) (4) and the locking jaw (6) for opening and closing adjustment, respectively, (2) is coupled between the pin (7), the leaf spring (8) formed with the outer expansion portion 10 and the incision (9) is inserted from the top to be caught by the engaging piece (5) to the door ( 11) When the opening angle of the fixing piece (1) (2) increases, the elastic spring of the leaf spring (8) approaches the center of the pin (7) to offset the acceleration by the restoring force of the leaf spring (7) It is configured to close automatically without

미설명부호 12는 고정벽체이다.Reference numeral 12 is a fixed wall.

이와같이 구성된 본 고안은 핀(7)으로 결합된 고정편(1)(2)에 판스프링(8)을 상부에서 삽입시키되 판스프링(8) 하부에 형성된 외향 확개부(10)를 이용하여 고정편(1)(2) 양측에 부착된 걸림편(5)에 용이하게 설치하고, 고정편(1)(2)은 각각 도어(11)와 고정벽체(12)에 설치하여 사용하면 된다.The present invention configured as described above is inserted into the leaf spring (8) to the fixing piece (1) (2) coupled to the pin (7) by using the outwardly extending portion 10 formed in the lower leaf spring (8) (1) (2) It is easy to install on the locking pieces 5 attached to both sides, and the fixing pieces 1 and 2 may be attached to the door 11 and the fixed wall 12, respectively.

이때 합승수지재 걸림편(5)은 판스프링(8)이 결합시 긁힘이나 외관의 손상을 보호하게 된다.At this time, the joint resin material locking piece (5) is to protect the scratch or damage of the appearance when the leaf spring (8) is coupled.

이어서 제3도와 같이 고정편(1)(2)을 설치한 다음 도어(11)를 약간 열면 걸림편(5)에 설치된 판스프링(8)의 선단이 벌려지면서 도어(11)가 탄력을 받게되고 도어(11)가 열린 상태에서 도어(11)에서 힘을 제거하면 도어(11)는 판스프링(8) 의 복원력에 의하여 자동적으로 닫히게 된다.Subsequently, as shown in FIG. 3, after the fixing pieces 1 and 2 are installed and the door 11 is slightly opened, the front end of the leaf spring 8 installed on the locking piece 5 is opened, and the door 11 is elastic. When the door 11 is opened and the force is removed from the door 11, the door 11 is automatically closed by the restoring force of the leaf spring 8.

또한, 제4도에 나타낸 바와같이 도어(11)를 활짝 열게되면 판스프링(8)의 탄력 작용점이 핀(11)의 중심과 근접하게 되어 판스프링(8)의 작용점이 최소한 핀(7)의 중심과 일치되거나 뒤로 이동하게 되면 도어(11)는 열린상태에서 복원되지 않고 개방된 상태를 유지하게 된다.In addition, as shown in FIG. 4, when the door 11 is opened wide, the resilient action point of the leaf spring 8 comes close to the center of the pin 11, so that the action point of the leaf spring 8 is at least at the pin 7. When the center coincides with or moves backward, the door 11 is kept in the opened state without being restored from the open state.

즉, 판스프링(8)의 탄력작용점이 핀(11)의 중심과 일직선상에 놓여지거나 뒤로 이동하지 않는한 항상 도어(11)는 판스프링(8)의 탄력으로 복원되고, 또한 개방된 상태에서도 도어(11)를 약간 움직여서 핀(7)의 중심 바로 직전까지만 판스프링(8)의 탄력작용점을 이동시키면 도어(11)는 자동적으로 충격없이 조용히 닫히게 되는 것이다.That is, the door 11 is always restored to the elasticity of the leaf spring 8, even in the open state, as long as the elastic action point of the leaf spring 8 does not lie in line with the center of the pin 11 or moves backward. By slightly moving the door 11 to move the resilient action point of the leaf spring 8 until just before the center of the pin 7, the door 11 is automatically closed silently and without impact.

이와같은 상태를 제7도에 나타낸 바와같이 좀더 구체적으로 설명하면, 도어(11)가 닫혀있을때는 판스프링(8)의 고정점이(A)(A') 상태로 있게 되어 핀(7)의 중심 중심선상 X에서 가장 멀리 위치하게 되어서 판스프링(8)의 탄력복원력은 P상태로 작용하고, 도어(11)를 열게되면 판스프링(8)의 고정점이 (B)(B'), (C)(C'), (D)(D')와 같은 상태로 이동되어 고정점이 (B)(B')에서 (C)(C')점으로 가까울수록, 즉 X선상에 근접할수록 판스프링(8)의 탄력은 P1,P2와 같은 상태로 작용하여 탄력은 강하지만(B)와(B'), (C)와(C')에서 반대로 작용하여 복원력은 상쇄되고만다.When this state is explained in more detail as shown in FIG. 7, when the door 11 is closed, the fixed point of the leaf spring 8 will be in the state (A) (A '), and the center of the pin 7 will be made. Since it is located farthest from the center line X, the elastic restoring force of the leaf spring 8 acts in the P state, and when the door 11 is opened, the fixed points of the leaf spring 8 (B) (B '), (C) (C '), (D) (D') moves in the same state so that the fixed point is closer to (C) (C ') from (B) (B'), that is, closer to the X-ray leaf spring (8) ) Elasticity acts in the same state as P 1 , P 2 , the elasticity is strong (B) and (B '), (C) and (C') acts in reverse, the restoring force is offset.

따라서 판스프링(8)의 고정점이 핀(7)의 중심에 가까울수록 판스프링(8)의 탄력은 강하지만 도어(11)가 닫힐려는 복원력은 그 중심이 핀(7)의 중심과 근접하여 상호 반대방향에서 상쇄되어 도어(11)가 닫힐려는 힘은 약하게 되므로 종래와 같이 가속도가 생기어 닫히는 충격적인 도어(11) 폐색이 없게 되는 것이다.Therefore, the closer the fixing point of the leaf spring 8 is to the center of the pin 7, the stronger the elasticity of the leaf spring 8, but the restoring force to close the door 11 is close to the center of the pin 7 Since the force to cancel in the opposite direction to close the door 11 is weakened so that there is no shock closing the door 11 is closed because of the acceleration as in the prior art.

또한, 고정점이 (C)(C')에 이르면 판스프링(8)의 탄력작용점이 P2상태로 작용되어 도어(11)의 탄력작용방향이 핀(7)의 중심과 일직선으로 되므로 도어(11)는 정지상태로 되고, 도어(11)를 완전히 열어젖혀 판스프링(8)의 고정점(D)(D')에 이르게 되면 판스프링(8)의 탄력은 P3방향으로 작용되어 도어(11)의 개방각도 최대치까지 뒤로 개방되어 복원되지 않고 열려진 상태를 유지하게 되는 것이다.In addition, when the fixed point reaches (C) (C '), the resilient action point of the leaf spring 8 acts in a P 2 state, so that the resilient action direction of the door 11 is aligned with the center of the pin 7. ) Is stopped and the door 11 is fully opened to reach a fixed point D (D ') of the leaf spring 8 so that the elasticity of the leaf spring 8 acts in the P 3 direction and the door 11 The opening angle of) will be opened back up to the maximum value and will remain open without restoring.

또한, 제5도에 나타낸 바와같이 경첩을 이용하지 않고 상, 하에 힌지만 설치한 도어(11)에는 고정편(1)(2)을 제6도에 나타낸 바와 같이 중앙의 양측으로 설치하여 사용할 수도 있다.In addition, as shown in FIG. 5, the fixing pieces 1 and 2 can be installed on both sides of the center as shown in FIG. have.

또한, 개폐상태 조정용 절곡부(3)(4)를 형성하므로 판스프링(8)의 고정점의 위치를 조정할 수도 있는 것이다.In addition, since the bent part 3 (4) for opening / closing adjustment is formed, the position of the fixed point of the leaf spring 8 can also be adjusted.

이와같이된 본 고안은 간단한 구조로서 도어를 열때는 수동으로 하고 닫을때는 자동으로 닫히도록 반자동으로 간편하게 사용할수 있으며, 설치공간이 종래에 비하여 대폭 줄어들게 되고, 도어(11)가 닫힐때 가속도가 생기어 충격을 주는 일이 없이 조용하고 원활하게 작동되는 등의 특징을 지닌 것이다.The present invention has a simple structure and can be easily used semi-automatically to open the door manually and close automatically when the door is closed, and the installation space is greatly reduced as compared to the prior art, and the acceleration is generated when the door 11 is closed. It is characterized by quiet and smooth operation without giving.
