Description

도어용 힌지장치Door hinge

본 발명은 도어용 힌지장치에 관한 것으로서, 좀더 상세하게는 유압을 이용하여 도어를 개,폐시키어 효율성 및 사용성을 높이도록 한 것이다.The present invention relates to a hinge device for a door, and more particularly, to open and close the door using hydraulic pressure to increase efficiency and usability.

일반적으로 도어를 열면 자동으로 닫히도록 한 도어용 힌지는 코일스프링을 사용하여 코일스프링의 탄력성에 의해 작동되고 있어 도어의 닫히는 탄력을 조정할 경우에는 스프링 자체적인 조정이 용이하지 못하기 때문에 이를 연결하는 레바의 길이조정등으로 조정하고 있다. 이는 외관상 분산된 구조를 갖고 있어 부피가 많고 사용상의 번거로움이 있었다.In general, the door hinge, which is automatically closed when the door is opened, is operated by the elasticity of the coil spring by using the coil spring. When adjusting the closing elasticity of the door, the spring itself cannot be easily adjusted. The length is adjusted by adjusting. It has a distributed structure in appearance and is bulky and hassle in use.

이러한 문제점을 감안하여 제안된 것으로, 한국 특허출원 제97-7637호 "여닫이 문용 힌지"가 공개되었던 바 그 기술적내용을 살펴보면, 도 1에서와 같이 도어(1)에 결합되는 하우징(500)과, 하우징(500) 내부에 일체로 구비되어 있는 스트로크조절부의 상부에 안치되는 구동부재(400) 및 완충장치(600)와, 하우징(500)의 중공부에 내삽되어 구동부재상에 안치되면서 도어프레임(2)에 고정되는 힌지축(300)과, 스트로크조절부에 정합되어 승강작용을 하면서 하부에 탄성설치되는 슬라이더(700)로 구성되어 있다.In view of the above problems, Korean Patent Application No. 97-7637 "Hinge Door Hinge" has been published. Looking at the technical contents of the housing 500 coupled to the door 1 as shown in FIG. 1, The drive member 400 and the shock absorber 600, which is settled on the upper part of the stroke control part integrally provided in the housing 500, and the door frame 2 while being inserted into the hollow part of the housing 500 and placed on the drive member. The hinge shaft 300 is fixed to the) and the slider 700 that is elastically installed in the lower portion while being engaged in the lifting and lowering action to the stroke control unit.

상기한 장치에서 힌지축(300)에 나사결합으로 승하강되는 슬라이더(700)가 하강되면서 그 하방에 위치한 스프링을 압축시키게 되고 도어(1)가 닫힐 때 무리한 충격을 받지 않고 서서히 닫히도록 함에 있어서, 완충장치(600)는 스프링의 탄발력으로 상승시 발생되는 공기압을 이용하고 있으나 이는 극히 제한공간으로는 완충력을 충분히 발휘하지 못하여 완충효과를 기대할 수 없을 뿐만 아니라, 완충장치(600)가 다수의 부품으로 결합되는 기구적인 구성으로 인하여 제작상 번거로움이 많고 조절구성이 까다롭게 이루어져 있고 그에 따른 잦은 고장이 발생될 수 있는 등의 문제점이 있다. 실제적으로 완충장치로서의 충분한 능력을 갖지 못하고 있다.In the above apparatus, the slider 700 which is lowered by screwing to the hinge shaft 300 is lowered while compressing a spring positioned below the hinge shaft 300 and gradually closing without being subjected to excessive shock when the door 1 is closed. The shock absorber 600 uses the air pressure generated when the spring is raised due to the elasticity of the spring. However, the shock absorber 600 does not exhibit sufficient buffering force in an extremely limited space, and thus the shock absorber 600 may not be expected. Due to the mechanical configuration combined with a lot of cumbersome in manufacturing and difficult to configure the configuration, there is a problem that can occur frequently according to the failure. In practice, it does not have sufficient capacity as a shock absorber.

이와같은 구성으로 이루어지는 본 발명은 도 6 및 도 7에서와 같이 각 취부판(6)(7)을 도어(20) 및 도어프레임(30)에 상단의 내측에 각각 체결, 고정한 다음 연결구(5)를 결합시키고 그 상단을 너트(8)로 조임한 후 하우징(1) 앗셈부리에서 상부로 돌출된 힌지축(3)을 연결구(5)에 끼우면서 도어(20)에 체결된 취부판(6)의 외측에 형성된 스플라인편(6a)에 하우징(1)의 상단에 형성된 스플라인홈(1a)에 맞게 끼우고 상단부에서 너트(16)로 힌지축(3)을 체결, 고정시키므로서 장착이 완료된다.The present invention having such a configuration is fastened and fixed to each of the mounting plate (6) (7) to the inside of the upper end of the door 20 and the door frame (30), respectively, as shown in Figs. And fasten the upper end with nuts (8), and then attach the hinge shaft (3) protruding upward from the housing (1) assembling part (5) to the mounting plate (6). Mounting is completed by fitting the spline piece 6a formed on the outside of the spline groove 1a formed at the upper end of the housing 1 and fastening and fixing the hinge shaft 3 with the nut 16 at the upper end.

그리고 설치전에 힌지축(3)만 약간 돌려주어 피스톤(11)이 약간 내려간 상태에서 하우징(1)의 상부 한쪽에 형성된 나사공(1d)을 통해 볼트를 체결하여 힌지축(3)에 형성한 걸림홈(3e)에 끼워 하우징(1)이 회전되지 못하게 한 상태에서 도어(20)에 장착이 완료후 다시 상기 나사공(1d)을 풀어 하우징(1)을 힌지축(3)과의 고정을 해제하게 되면 스프링(12)의 탄성력에 의하여 하우징(1)이 원위치로 회전하려는 원상복귀력에 의하여 도어(20)가 도어프레임(30)에 가압되는 상태로 밀착되게 닫히게 된다.Then, only the hinge shaft 3 is slightly rotated before installation, and the bolt 11 is fastened and the bolt is fastened through the screw hole 1d formed on the upper side of the housing 1 to form the hinge shaft 3. After the mounting on the door 20 is completed by inserting the groove 3e into the groove 3e, the screw hole 1d is released again to release the housing 1 from the hinge shaft 3. In this case, the door 20 is closed in a state in which the housing 1 is pressed against the door frame 30 by the original return force to rotate the housing 1 to the original position by the elastic force of the spring 12.

상기한 간단한 설치과정으로 설치가 완료된 본 발명은 도어(20)를 열면 힌지축(3)은 도어프레임(30)에 체결되는 취부판(7)에 고정상태이기 때문에 회전하지 않고 도어(20)에 취부판(6)으로 체결, 고정된 하우징(1)이 함께 회전함에 따라 하우징(1)에 키이(1b)(11a)로 연결된 피스톤(11)도 함께 회전되는데 피스톤(11)이 힌지축(3)의 나선축(11a)에 결합되어 있어 나선결합부에 의하여 피스톤(11)이 하강하여 유체와 함께 스프링(12)을 밀면서 하강하여 도어(20)를 적정힘으로 밀어 열 수 있도록 한다.In the present invention, the installation is completed by the simple installation process described above, the hinge shaft 3 is fixed to the mounting plate 7 fastened to the door frame 30 when the door 20 is opened. As the housing 1 fixed and fastened by the mounting plate 6 rotates together, the piston 11 connected to the housing 1 by the keys 1b and 11a also rotates together, and the piston 11 rotates on the hinge shaft 3. Is coupled to the spiral shaft (11a) of the piston by the spiral coupling portion 11 is lowered by pushing the spring 12 with the fluid to lower the door 20 by pushing the appropriate force to open.

그리고 피스톤(11)이 하강시 유체는 피스톤(11)의 중앙에 형성된 통공(11b)을 통하여 볼(14)이 압력에 의하여 밀리면서 유체가 올라와 하강에 따라 넓어지는 공간으로 유입과 동시에 나선결합부의 틈새, 기타 틈새를 통하여 상부의 상,하 통로(1e)로 빠져 유로(2a)로 유입되고 유로(2a)에 끼워진 조절밸브(4)의 조정봉(4a)과 유로(2a)의 사이에 형성되는 공간을 통하여 하방으로 빠져 나가게 되는데 조절밸브(4)의 조정으로 조정봉(4a)을 돌려줌에 따라 유체가 빠져 나가는 공간이 조정되어 도어의 오픈속도를 조정할 수 있게 되는 것이다.When the piston 11 descends, the fluid is pushed by the pressure through the through hole 11b formed at the center of the piston 11, and the fluid rises into the space where the fluid rises and descends. It is formed between the adjusting rod 4a and the flow passage 2a of the control valve 4 inserted into the flow passage 2a and inserted into the flow passage 2a through the gap and other gaps. Out through the space is to go out downward, by adjusting the adjusting valve (4) by turning the adjusting rod (4a) is to adjust the open space of the door by adjusting the space in which the fluid exits.

한편, 도어(20)를 닫으면 상기한 반대 작용 즉 하우징(1)의 역회전에 의하여 피스톤(11)이 나사결합부에 의한 상승과 함께 스프링(12)의 탄성력을 받으면서 상승되는데 이때 피스톤(11)의 중앙부에 통로는 볼(14)이 흡입력에 의한 작용으로 차단되고 피스톤(11)내 및 그 주변에 있는 유체는 유로(2a)를 통하여 하부의 실린더실(1c)로 유입되게 되는데 유로(2a)의 공간이 협소하여 유체이 서서히 빠지기 때문에 도어(20)는 일시에 닫히지 않고 유체압력을 받으면서 적정속도로 서서히 닫히게 되는 것이다. 닫히는 속도는 상기의 오픈과정에서와 같이 조절밸브(4)의 조정으로 조정봉(4a)을 돌려줌에 따라 유체이 빠져 나가는 공간이 조정되어 닫히는 속도를 조정할 수 있게 되는 것이다.On the other hand, when the door 20 is closed, the piston 11 is raised while receiving the elastic force of the spring 12 together with the upward movement by the screw coupling part due to the reverse action of the above-described reverse rotation of the housing 1, wherein the piston 11 is In the central part of the passage, the ball 14 is blocked by the action of suction force, and the fluid in and around the piston 11 is introduced into the lower cylinder chamber 1c through the flow path 2a. Since the space is narrow and the fluid is gradually released, the door 20 is closed at an appropriate speed while being subjected to the fluid pressure without being closed at once. The closing speed is to adjust the closing speed by adjusting the space in which the fluid exits as the adjusting rod 4a is turned by adjusting the control valve 4 as in the opening process.

그리고 도어(20)가 닫히는 도중 피스톤(11)이 상사점에 이르게 되면 피스톤(11)의 하부 단턱측면부가 피스톤(11)의 상사점 바로 아래에 위치한 통로(1e)를 일시적으로 차단하게 되어 유체의 유출량이 줄어들게 되므로서 일정속도로 닫히는 도어(20)는 속도가 감속되어 도어(20)가 거의 닫힐 때 닫히는 속도를 줄여 닫힐 때 충격 및 소음 등을 차단할 수 있게 되는 것이다. 즉, 도어(20)가 유체의 제어에 의하여 적정속도로 일정하게 닫히다가 닫히기 직전에 닫히는 속도가 감속되어 부드럽게 닫히도록 한 것이다.When the piston 11 reaches the top dead center while the door 20 is closed, the lower stepped side surface portion of the piston 11 temporarily blocks the passage 1e located just below the top dead center of the piston 11, The door 20 that is closed at a constant speed as the outflow is reduced is to reduce the speed to close when the door 20 is almost closed to block shocks and noises when the door 20 is closed. That is, the door 20 is constantly closed at an appropriate speed under the control of the fluid, and the speed at which the door 20 is closed just before closing is decelerated and closed smoothly.
