제1도는 본 고안의 분해 사시도.1 is an exploded perspective view of the present invention.

제2도는 본 고안의 조립상태 종단면도.2 is a longitudinal cross-sectional view of the assembled state of the present invention.

제3도는 본 고안의 요부 작동상태를 나타낸 횡단면도로서,3 is a cross-sectional view showing the main operation state of the present invention,

(a)는 도어의 폐문직전의 상태이고,(a) is the state just before the closing of the door,

(b)는 도의 폐문상태도이다.(b) is a closed state diagram of FIG.

본 고안은 문을 지지하는 회전축 중간에 캠을 형성하고 그 캠에 스프링이 탄설된 활동자를 접설하여 문의 회전축을 탄지하는 공지의 것에 있어서, 회전축 내부에 유압 완충장치를 부가하여 문의 폐문상태가 정확하고 부드럽게 되도록 한 것을 특징으로 하는 도어힌지에 관한 것이다.The present invention forms a cam in the middle of the rotating shaft supporting the door and attaches a spring-loaded activator to the cam to support the rotating shaft of the door. It relates to a door hinge, characterized in that to be smooth.

종래에는 문의 자동폐문에 따른 탄발력이 환동자를 탄지시키는 스프링만으로서 감당하게 되어 있으므로 문의 폐문상태를 보면 열렸던 문의 회전복귀 폐문될 때 스프링의 탄발복원력과 문자체의 회전 복귀관성에 의하여 문틀에 정확히 일치되어 정지못하고 폐문상태를 지나쳐 문틀 내외측을 수회 진자운동을 한 후에야 비로소 정지되는 폐문작동상의 부정확한 문제점이 있고 이와 같은 부정확한 작동을 반복함에 따라 단기간만 사용하여도 문의 폐문 각도가 문틀과 정확히 일치되지 못하며 자동 폐문작동도 급격한 회전운동에 의하므로써 부드럽지 못한등의 결점이 있었다.Conventionally, the repulsive force due to the automatic closing of the door is handled only by the spring that holds the walker. Therefore, when the door is closed, the resilience of the door is exactly matched to the door frame by the resilience of the spring and the rotational return inertia of the font. There is an inaccurate problem in the closing door operation only after several pendulum movements in and out of the door frame through the closed state without stopping, and the closing angle of the door is exactly the same as the door frame even if it is used for a short period of time. Also, the automatic closing operation was not smooth due to the rapid rotational movement.

본 고안은 전술한 바의 종래 결점을 개선하기 위하여 회전축 내부에 급격한 회전운동을 완화시키는 유압 완충장치를 부설하므로써, 문의 폐문시 일정각도에 도달하면 유압력에 의해 폐문 회전력이 완화되면서 부드럽게 복귀하여 문틀에 정확히 일치된 상태에서 곧바로 정지 폐문되게 한 것인데, 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention by installing a hydraulic shock absorber to alleviate the sudden rotational movement inside the rotating shaft in order to improve the conventional drawbacks described above, when the door closes at a certain angle when the door is closed by the hydraulic force to smoothly return the door frame In the state exactly matched to stop immediately closed, which will be described in detail by the accompanying drawings as follows.

갑체(1) 내부에 회전축(2)을 축설하고 회전축(2)의 중간에 형성된 캠(3)에 스프링(5)(5')이 탄설된 활동자(4)를 접설하여 문을 자동 폐문하게 하는 공기의 것에 있어서, 회전축(2)의 내부에 실린더(6)를 형성하고 그 실린더(6) 내부에 만곡 돌기부(7')를 갖는 피스턴(7)을 스프링(8)으로 장착하여 피스턴(7)의 만곡 돌기부(7')가 갑체(1)의 측벽(1')에 접리 가능케하며 실린더(6) 상하방에 역지변(9')(10')을 갖는 유입구(9)와 배출구(10)를 외부로 연통되게 천설하여 배출구(9) 일측에 유압조절 콕크(11)를 설치하고 갑체(1)의 저면 회전축(2)의 지축부에 오일의 집유실(12)을 형성하여 갑체(1) 내부하방에 일정량 주입된 오일(13)이 그 집유실(12)내로 계속 유통되게 구성한 것으로 도면중 부호 14는 피스턴 고정용 와셔, 15는 피스턴링, 16은 패킹링, 17은 베아링, 18,18'는 캠의 작동을 원활히 하기 위한 로울러를 각각 표시한다.The rotating shaft (2) is built up inside the body (1), and the cam (3) formed in the middle of the rotating shaft (2) is folded with an active member (4) loaded with springs (5, 5 ') to allow the door to close automatically. In the air, the piston 6 is formed by forming a cylinder 6 inside the rotation shaft 2 and having a curved protrusion 7 'inside the cylinder 6 by a spring 8 to form a piston 7. The inlet 9 and the outlet 10 having a curved projection 7 'of the body 1 foldable on the side wall 1' of the upper body 1 and having a reverse side 9 ', 10' above and below the cylinder 6; Is installed in communication with the outside, the hydraulic control cock 11 is installed on one side of the outlet 9, and the oil collecting chamber 12 is formed in the supporting shaft of the bottom rotating shaft 2 of the upper body 1 to the upper body 1 In the drawing, the oil 13 injected in a predetermined amount is continuously flowed into the collecting chamber 12. In the drawing, reference numeral 14 denotes a piston fixing washer, 15 a piston ring, 16 a packing ring, 17 a bearing, and 18 and 18. 'Cam operation Each displays a roller for hwalhi.

이와 같은 본 고안은 문을 열어 회전축(2)의 캠(3)이 회전하면 그 캠(3)이 활동자(4)를 외측으로 이동시켜 스프링(5)(5')을 압축하고 열린문을 자유롭게 놓으면 압축되었던 스프링(5)(5')의 탄발력에 의해 활동자(4)가 다시 내측으로 이동 복귀하면서 회전되어 있던 캠(3)을 원상으로 복귀 회전시켜서 문을 자동폐문하게 되는 것은 공지의 것과 같으나, 자동폐문시 회전축(2)이 일정 각도까지는 스프링(5)(5')의 탄발력을 충분히 받아 폐문되다가 일정각도를 지나 급격한 회전력을 받을 즈음하면 회전축(2) 내부에 장착된 유압 완충장치에 의하여 회전력이 완화되어 부드럽고 정확한 폐문작동이 이루어지는 것이 특징인데, 그 작동을 더 구체적으로 설명하면 다음과 같다.In the present invention, when the cam 3 of the rotating shaft 2 is rotated to open the door, the cam 3 moves the actuator 4 to the outside to compress the springs 5 and 5 'and freely open the door. When it is released, it is known to automatically close the door by rotating the rotated cam 3 to the original position while the actuator 4 moves back to the inner side by the elastic force of the compressed springs 5 and 5 '. The same, but the hydraulic shock absorber mounted inside the rotating shaft (2) when the rotating shaft (2) is closed enough to receive a resilient force of the spring (5) (5 ') until a certain angle when the automatic closing closes and receives a sudden rotational force over a certain angle It is characterized by the rotational force is relaxed by the smooth and accurate closing operation, the operation will be described in more detail as follows.

즉, 문이 열려 회전축(2)이 회전하면 그 회전축(2)의 실린더(6)내에 전입상태로 장착되어 있던 피스턴(7)의 만곡 돌기부(7')가 갑체(1)의 측벽(1')으로부터 분리 이탈됨과 함께 내부 스프링(8)의 탄발력이 작용함에 따라 피스턴(7)이 실린더(6)로부터 빠져나오면서 유입구(9)를 통하여 집유실(12)내의 오일(13)을 실린더(6) 내부로 흡입 저장하게 되고, 폐문시에는 일정 각도까지는 활동자(4)에 탄설된 스프링(5)(5')의 복원탄력에 의해 통상의 도어힌지와 같이 회전축(1)이 비교적 빠른 속도로 복원 회전되다가 회전축(2)이 일정각도에 도달해 피스턴(7)의 만곡 돌기부(7')가 갑체(1)의 측벽(1')에 접촉하게 되면 만곡 돌기부(7')의 회전반경이 점차 작아짐에 따라 피스턴(7)이 다시 스프링(8)을 압축하면서 실린더(6) 내부로 진입을 개시하게 된다.That is, when the door is opened and the rotary shaft 2 rotates, the curved projection 7 'of the piston 7 mounted in the indent state in the cylinder 6 of the rotary shaft 2 is moved to the side wall 1' of the body 1. As the elastic force of the inner spring 8 acts as it is separated and separated, the piston 13 exits the cylinder 6 and the oil 13 in the collecting chamber 12 is transferred to the cylinder 6 through the inlet 9. The suction shaft is stored inside, and when the door is closed, the rotating shaft 1 is restored at a relatively high speed like a normal door hinge by the restoring elasticity of the springs 5 and 5 'installed on the operator 4 up to a certain angle. When the rotating shaft 2 reaches a certain angle and the curved protrusion 7 'of the piston 7 contacts the side wall 1' of the upper body 1, the radius of rotation of the curved protrusion 7 'is gradually reduced. As a result, the piston 7 starts to enter the cylinder 6 while compressing the spring 8 again.

그러나 이때 피스턴(7)은 실린더(6) 내부에 오일(13)이 충진된 상태이므로 내부유압력의 저항을 받아 급속히 진입되지 못하고 실린더(6)내의 오일이 배출구(10)를 통해 모두 배출될 때가지 서서히 진입할 수 밖에 없게 된다.However, at this time, since the piston 7 is filled with the oil 13 inside the cylinder 6, the oil 7 is not rapidly entered under the resistance of the internal oil pressure, and the oil in the cylinder 6 is discharged through the outlet 10. The only way to enter is slowly.

따라서 이와 같이 피스턴(7)의 만곡돌기(7')가 서서히 실린더(6)내로 진입됨에 따라 회전축(2)의 회전속도도 완속으로 변환되고 이에 따라 문도 일정각도 회전 후에는 완만한 속도로 부드럽게 닫히게 되고, 이렇게 하여 실린더(6)내의 오일(12)이 완전 배출될 즈음하면 피스턴(7)의 만곡돌기(7')의 정점부가 갑체(1) 외측벽(1')에 접선 방향으로 접촉하면서 문이 완전 정지되어 문틀을 지나침이 없이 정확하게 폐문되는 것이다.Therefore, as the curved protrusion 7 'of the piston 7 gradually enters the cylinder 6, the rotation speed of the rotation shaft 2 is also converted to a slow speed, and thus the door is smoothly closed at a gentle speed after a certain angle rotation. In this way, when the oil 12 in the cylinder 6 is completely discharged, the apex of the curved projection 7 'of the piston 7 contacts the outer wall 1' of the upper body 1 in a tangential direction and the door is closed. It stops completely and closes accurately without passing the door frame.

따라서 이와 같은 본 고안에 의하면 문이 폐문됨에 있어서 일정 각도까지는 통상의 도어힌지와 같이 비교적 빠른 속도로 닫히다가 일정 각도에 도달하면 회전측 내부에 설치된 유압 완충장치에 의하여 문이 서서히 감속 회전되면서 문틀에 정확히 일치된 후 어긋남이 없이 정지하게 되므로 문의 폐문작동이 정확함은 물론 부드러워서 고장이 적고 장기간 사용할 수 있는 효과를 나타나게 된다.Therefore, according to the present invention, when the door is closed, it closes at a relatively high speed like a normal door hinge until a certain angle, and when the door reaches a predetermined angle, the door is slowly decelerated and rotated by a hydraulic shock absorber installed inside the rotating side. After the exact match, it stops without any misalignment, so the door closing operation is not only accurate, but also smooth, so there is less trouble and the effect can be used for a long time.
