자동 문닫음 장치 {Automatic door closing device}Automatic door closing device

본 고안은 각종문을 자동으로 닫히게 하는 장치로서 더욱 상세하게는 스프링과 나사의 유압유를 이용하여 자동으로 문을 닫히게 하는 장치이다 일반적으로 문을 자동으로 닫히게 하기 위하여 스프링을 사용하거나 문 위에 설치 할 수밖에 없는 자동 닫힘 장치를 이용하고 있으나 스프링을 사용한 장치는 너무 빨리 닫힐뿐 아니라 소음이 심하고 수명이 짧으며 문위에 설치 할 수밖에 없는 자동 닫힘 장치는 덩치가 크고 제작비가 비싸며 문위에 설치함으로 인해 미관상 좋지 않았다The present invention is a device that automatically closes various doors, and more specifically, a device that automatically closes the door by using hydraulic oil of a spring and a screw. In general, it is necessary to use a spring or install on the door to automatically close the door. Although the automatic closing device is used without a spring, the spring closing device is not only closed too fast, but also has a lot of noise, short lifespan, and can only be installed on the door.

본고안은 상기와 같은 문제점을 해소 하기 위해 스프링과 나사와 유압유를 이용하여 소형으로 제작할수 있게 하고 설치후 미관을 좋게 하는데 본 고안의 목적이 있는 것이다 이와 같은 목적을 달성하기 위해 본 고안은 문이 자동으로 닫히고 소형으로 제작하기 위해 스프링과 나사를 설치 하였고 문이 천천히 닫히도록 하기위하여 유압유의 흐름량을 조절 할수 있게 하였으며 또한 본 유압유는 스프링의 소음방지는 물론 스프링의 수명을 반영구적으로 할수있으며 설치는 문옆에 하여 미관을 좋게 하는데 특징이 있다In order to solve the above problems, the present invention aims to make it compact by using springs, screws, and hydraulic oil, and to improve aesthetics after installation. Spring and screws are installed to close automatically and compactly, and the flow rate of hydraulic oil can be adjusted to close the door slowly. In addition, this hydraulic oil can not only prevent the noise of the spring but also semi-permanently the life of the spring. It is characteristic to improve aesthetics by

본 고안은 중간판(5)의 회전방지를 위한 핀(1b)과 문의 닫히는 속도를 조절하기 위해 유압유의 흐르는 유량을 조절하기 위한 유량조절볼트(7)를 조립하기위한 조절구멍(1a)과 벽에 고정을 위한 고정구멍(1c)을 형성한 외통(1)에 토션스프링(3)을 고정하기위한 하부고정홈(2a)을 형성한 밑판(2)과 조립 및 해체를 쉽게 하기위한 윗판(2')을 조립한다,The present invention is a wall and the adjustment hole (1a) for assembling the flow control bolt (7) for adjusting the flow rate of the hydraulic oil to adjust the closing speed of the door and the pin (1b) for preventing rotation of the intermediate plate (5) A bottom plate 2 having a lower fixing groove 2a for fixing the torsion spring 3 to the outer cylinder 1 having a fixing hole 1c for fixing thereto and an upper plate 2 for easy assembly and disassembly. Assemble '),

토션스프링(3)의 한쪽끝은 밑판(2)의 고정홈(2a)에 고정되어지고 다른 한쪽끝은 중간봉(4)에 형성된 상부고정홈(4b)에 고정 되어진다One end of the torsion spring 3 is fixed to the fixing groove 2a of the base plate 2 and the other end is fixed to the upper fixing groove 4b formed on the intermediate bar 4.

중간봉(4)은 문의 회전운동 및 스프링의 회전운동을 직선운동으로 변환시키기 위한 숯나사(4a)와 토션스프링(3)의 상부를 고정 할수 있게 상부고정홈(4b)를 형성하고 중간봉(4)이 위로 이탈하는 것을 방지하기 위한 스냅링(4c)이 장착되어진다, 중간봉(4)의 상부에는 회전반경을 맞추기위한 링크(6)에 고정 하기 위하여 나사가 있는 상부돌출부(4d)를 형성하고 중간판(5)은 문의 회전운동 및 스프링의 회전운동을 직선운동으로 변환시키 위한 암나사(5a)와 문이 천천히 닫히도록 유압유의 이송량 조절을 위한 볼(5b')과 스프링(5b')이 장착되어진 구멍(5b) 및 회전방지를 위한 홈(5c)을 형성하였다, 미설명 부호 (1d)(1e)(1f)(1g)는 유량조절구멍이고 (8)은 오일링, (10)은 문, (11)은 벽이고 (20)은 본장치 내부에 채워진 유압유이다The intermediate bar 4 forms an upper fixing groove 4b to fix the upper portion of the char screw 4a and the torsion spring 3 for converting the rotational motion of the door and the rotational motion of the spring into a linear motion. 4) A snap ring 4c is mounted to prevent it from escaping upward. The upper part of the intermediate rod 4 is formed with a screwed upper protrusion 4d to fix it to the link 6 for adjusting the rotation radius. The intermediate plate 5 has a female screw 5a for converting the rotational motion of the door and the rotational motion of the spring into a linear motion, and a ball 5b 'and a spring 5b' for adjusting the amount of hydraulic oil feed so that the door closes slowly. The holes 5b to be mounted and the grooves 5c for preventing rotation are formed. Reference numerals 1d, 1e, 1f, and 1g are flow rate adjusting holes, 8 are oil rings, and 10 are Door, 11 is wall and 20 is hydraulic oil filled inside the main unit

이상의 부품으로 구성된 본장치는 도 8에서 문(10)을 앞으로 당기면 링크(6)가 앞쪽으로 이동하며 중간봉(4)이 링크가 움직인 각도만큼 회전한다 중간봉(4)에 형성된 숯나사(4a)가 회전하며 이회전력은 암나사(5a)를 통하여 중간판(5)을 밑에서 위로 올려 보낸다, 중간판(5)이 상승시 볼(5b')이 유압의 힘에 의해 밑으로 내려가 구멍(5b)이 활짝 열려 유압유가 위에서 밑으로 빨리 흘러가 문이 빨리 쉽게 열린다, 이때 상부고정홈(4b) 및 하부고정홈(2a)에 장착된 토션스프링(3)이 감겨 복원력이 생긴다 토션스프링(3)의 복원력은 중간봉(4) 및 숯나사(4a) 및 암나사(5a)를 통해 중간판(5)을 하강시킨다, 이때 볼(5b')은 스프링(5b')에 의하여 위로 올라가 구멍(5b)이 닫히므로 유압유는 유량조절구멍(1d)(1e)(1f)(1g)을 통하여 유압유가 밑에서 위로 천천히 흘러 가므로 문이 천천히 닫힌다, 속도조절은 유량조절볼트(7)의 일자홈(7a)을 오른쪽으로 돌리면 유량조절구멍(1f)이 좁아져 유압유가 천천히 흘러 문이 천천히 닫히고 문의 마지막 닫히는 순간의 속도를 조절 하기 위해서는 문이 닫히는 순간에는 유량조절구멍(1e)이 중간판(5)에 의해 닫히므로 유압유가 하부에서 유량조절구멍(1d)(1f)(1g)을 통하여 상부로 흘러가므로 일자홈(7a)을 조금씩 돌려 유량조절볼트(7)의 면(7c)이 유량조절구멍(1d)의 상부에 오면 유압유가 많이 흘러 문이 빨리 닫힌다 다시 유량조절볼트(7)를 조금씩 돌려 유압유가 적게 흘러 문이 천천히 닫히다가 유량조절볼트(7)를 90 °만큼 돌렸을때 유압유가 최고 적게 흘러 문이 최고 천천히 닫히다, 또한 핀(1b) 및 홈(5c)은 숯나사(4a) 및 암나사(5a)의 회전시 중간판(5)의 회전을 방지한다In the device composed of the above components, when the door 10 is pulled forward in FIG. 8, the link 6 moves forward and the middle rod 4 rotates by the angle at which the link is moved. 4a) is rotated and the turning power is raised from the bottom to the middle plate 5 through the female thread 5a. When the middle plate 5 is raised, the ball 5b 'is lowered by the hydraulic force and the hole 5b is rotated. ), The hydraulic oil flows quickly from the top to the bottom, and the door opens easily. At this time, the torsion spring (3) mounted on the upper fixing groove (4b) and the lower fixing groove (2a) is wound so that the restoring force is generated. The restoring force lowers the intermediate plate 5 through the intermediate rod 4, the charcoal screw 4a and the female screw 5a, wherein the ball 5b 'is lifted up by the spring 5b' and the hole 5b is As it closes, the hydraulic fluid flows slowly from the bottom up through the flow adjusting holes 1d, 1e, 1f and 1g, To adjust the speed, turn the straight groove 7a of the flow adjusting bolt 7 to the right to narrow the flow adjusting hole 1f so that the hydraulic oil flows slowly, the door closes slowly, and the door is closed to adjust the speed at the last closing time of the door. At the moment of closing, since the flow regulating hole 1e is closed by the intermediate plate 5, the hydraulic oil flows from the lower part to the upper part through the flow adjusting holes 1d, 1f and 1g, so that the straight groove 7a is turned little by little. When the surface 7c of the adjustment bolt 7 is in the upper part of the flow adjusting hole 1d, the hydraulic oil flows a lot and the door closes quickly. Again, the hydraulic oil flows a little by turning the flow adjusting bolt 7 little by little, and the door closes slowly, When the bolt 7 is turned by 90 °, the hydraulic oil flows in the smallest and the door closes the most slowly. In addition, the pins 1b and the grooves 5c have the intermediate plate 5 when the char 4a and female 5a are rotated. Prevents rotation

이상에서 상술한 바와 같이 스프링과 나사를 설치함 으로서 소형으로 제작할수 있을뿐 아니라 제작비가 싸게들며 유압유를 이용하여 문이 천천히 닫히고 닫히는 속도를 조절 할수 있고 또한 이유압유는 스프링의 소음방지는 물론 스프링의 수명을 반영구적으로 할수 있으며 문옆으로 설치하고 구조가 간단하여 미관상에도 좋을뿐만 아니라 중량의 방화문에서 부터 경량의 가구 및 싱크대의 문등 용도가 다양하다As described above, by installing the spring and screw, not only can be manufactured in a small size, but also the manufacturing cost is low, and the hydraulic oil can be used to adjust the speed of closing and closing the door slowly. It can be used for semi-permanent life. It is installed on the side of the door and its structure is simple, so it is not only good in appearance but also has a variety of uses from heavy fire door to light furniture and sink door.
