Description

자동 문닫음장치 {Automatic door closing device}Automatic door closing device

본고안은 각종문을 자동으로 닫히게하는 장치로서, 더욱상세하게는 스프링과 나사와 유압유를 이용하여 자동으로 문을 닫히게하는 장치이다.This paper is a device for automatically closing various doors, and more specifically, a device for automatically closing doors using springs, screws, and hydraulic oil.

일반적으로 문을자동으로 닫히게하기 위하여 스프링을 사용하거나 도 10 과 같이 문위에 설치 할수 밖에 없는 자동닫힘 장치를 이용하고있으나 스프링을 이용한 닫힘장치는 너무 빨리 닫힐뿐 아니라 소음이 심하고 수명이 짧으며 문위에 설치 할 수밖에 없는 자동닫힘 장치는 덩치가 크고 제작비가 비싸며 문 위쪽에 설치함으로 인해 미관상 좋지않았다.In general, a spring is used to automatically close the door, or an automatic closing device that can only be installed on the door as shown in FIG. 10 is used, but the closing device using the spring is not only closed too quickly, but also has a high noise, short life span, The automatic closing device, which can only be installed, was large and expensive, and it was not good because of the installation above the door.

본 고안은 상기와 같은 문제점을 해소하기 위해 스프링과 나사와 유압유를 이용하여 소형으로 제작 할수 있게 하고 설치후 미관을 좋게 하는데 본 고안의 목적이 있는 것이다.The present invention is to make a small size using the spring and screws and hydraulic oil to solve the above problems, and to have a good aesthetics after installation is the purpose of the present invention.

이와같은 목적을 달성하기위해 본 고안은 문이 자동으로 닫히고 소형으로 제작 하기위해 스프링 과 나사를 설치하였고 문이 천천히 닫히도록 하기 위하여 유압유의 흐름량을 조절 할수 있게 하였으며 또한 본 유압유는 스프링의 소음방지는 물론 스프링의 수명을 반영구적으로 할수있으며 설치는 문옆에서 설치하여 미관을 좋게 하는데 특징이있다.In order to achieve this purpose, the present invention installed the spring and screw to close the door automatically and make it compact, and it is possible to adjust the flow rate of the hydraulic oil so that the door closes slowly. Of course, the life of the spring can be semi-permanent, and the installation is characterized by good installation by installing at the door.

이하 첨부된 도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings as follows.

본고안은 양 끝에 나사(1a)가 있고 중간판(8)의 회전방지를 위한 핀(1b)를 형성한 외통(1), 벽에 설치를 위해 구멍(2b)이 뚫려져 있고 외통(1)에 부착된 판(2), 본장치의 조립 및 해체를 쉽게 하기위한 가장자리에 나사(3a)가 난 윗판(3), 스프링(5)을 고정 하기위한 돌출부(4b)가 있고 조립 및 해체를 쉽게 하기위한 가장자리에 나사(4a)가 난 밑판(4), 중간봉(7)에 고정하기위한 고정판(5a)를 부착한 스프링(5). 문의 회전반경을 맞추기위해 나사(6a)로 길이조절이 가능 하도록한 링크(6), 링크(6)에 전달된 힘을 스프링(5)에 전달하고 스프링(5)의 복원력을 링크(6)에 전달하는 중간봉(7), 또한 중간봉(7)은 문의 회전운동 및 스프링의 회전운동을 직선운동으로 변환시키기 위한 숯나사(7a) 및 고정판(5a)를 장착 할수 있는 홈(7a) 과 중간봉(7)이 위로 이탈 하는것을 방지하기 위한 턱(7c)를 형성하였다.This case consists of an outer cylinder (1) having screws (1a) at both ends and a pin (1b) for preventing rotation of the intermediate plate (8), a hole (2b) drilled for installation in a wall, and an outer cylinder (1) Plate (2) attached to it, top plate (3) with screw (3a) on the edge for easy assembly and disassembly of the device, and projection (4b) for fixing the spring (5), and easy to assemble and dismantle A spring (5) with a fixing plate (5a) for fixing to a bottom plate (4) with a screw (4a) and an intermediate rod (7) at the edge thereof. In order to adjust the radius of rotation of the door, the force transmitted to the link 6 and the link 6, which can be adjusted in length by the screw 6a, is transmitted to the spring 5, and the restoring force of the spring 5 is transferred to the link 6 Intermediate rod 7 for transmitting, also intermediate rod (7) and the groove (7a) that can be mounted to the charcoal screw (7a) and fixing plate (5a) for converting the rotational movement of the door and the rotational movement of the spring into linear movement The jaw 7c was formed to prevent the rod 7 from escaping upward.

문의 회전운동 및 스프링의 회전운동을 직선운동으로 변환시키기 위한 암나사(8a) 와 문이 천천히 닫히도록 유압작동유의 이송량 조절을 위한 날름막(8b) 과 작은구멍(8b') 및 회전방지를위한 홈(8c)를 형성한 중간판(8), 미설명된 번호(9)는 오일링 이고 (10)은 본장치 내부에 채워진 유압유이다.Female screw 8a for converting the rotational movement of the door and the rotational movement of the spring into linear movement, and the diaphragm 8b and the small hole 8b 'for adjusting the feed amount of the hydraulic fluid so that the door closes slowly, and the groove for preventing rotation ( Intermediate plate 8 forming 8c), the number 9 which is not described, is an oil ring and 10 is hydraulic oil filled inside the apparatus.

이상의 부품으로 구성된 본장치는 도 8 에서 문(20)이 사람의 힘으로 열리면 링크(6)가 앞쪽으로 이동하며 중간봉(7)이 링크가 움직인 각도만큼 회전한다 중간봉(7)에 부착된 숫나사(7a)가 회전하며 이회전력은 암나사(8a)를 통해 중간판(8)을 밑으로 민다, 중간판(8)이 하락시 날름막 (8b)가 활짝 열려 유압유가 밑에서 위로 빨리 흘러가 문이 빨리 쉽게 열린다, 이때 중간봉(7) 및 홈(7b)에 장착된 고정판(5a)을 통하여 스프링(5)이 감겨 복원력이 생긴다, 문이 열린 상태에서 손을 놓으면 스프링(5)의 복원력으로 문이 닫힌다, 스프링의 복원력은 중간봉(7) 및 숫나사(7a)와 암나사(8a)를 통해 중간판(8)을 상승시킨다, 이때 날름막(8b)은 닫히고 작은구멍(8b')을 통하여 유압유가 위에서 밑으로 천천히 흘러 가므로 문이 천천히 닫힌다, 또한 핀(1b) 및 홈(8c)은 숫나사(7a) 및 암나사(8a)의 회전시 중간판(8) 자체의 회전을 방지한다In the device composed of the above components, in FIG. 8, when the door 20 is opened by human force, the link 6 moves forward and the middle rod 7 rotates by the angle at which the link is moved. The male screw 7a is rotated and the turning force pushes the middle plate 8 downward through the female screw 8a. When the middle plate 8 falls, the diaphragm 8b opens wide and the hydraulic oil flows quickly from the bottom to the door. It is easily opened. At this time, the spring 5 is wound through the fixing plate 5a mounted on the middle rod 7 and the groove 7b, so that the restoring force is generated.When the door is opened, the hand is released by the restoring force of the spring 5. The restoring force of the spring raises the intermediate plate 8 through the intermediate rod 7 and the male screw 7a and the female screw 8a, wherein the diaphragm 8b is closed and the hydraulic oil flows through the small hole 8b '. The door closes slowly because it flows downward slowly, and the pins 1b and the grooves 8c are male threads 7a and Upon rotation of the screw (8a) to prevent the rotation of the intermediate plate (8) itself

문을 닫는데 필요한 스프링의 복원력에 대해 수식으로 계산하면The formula for the spring's resilience to close the door

도 11에서 문(20)을 사람이 0.2kg의 힘으로 밀면 문이열리는 것으로 가정,In FIG. 11, it is assumed that the door is opened when a person pushes the door 20 with a force of 0.2 kg.

모멘트(M) = F L F : 힘의크기 L : 거리Moment (M) = F L F: magnitude of force L: distance

M = F L = Fㆍ10cm = 0.2kgㆍ90cmM = F L = F 10 cm = 0.2 kg 90 cm

∴ F = 1.8kg∴ F = 1.8 kg

∴ 스프링 모멘트 M = 0.18 kg-m x 1.1 ≒ 0.2 kg-m∴ spring moment M = 0.18 kg-m x 1.1 ≒ 0.2 kg-m

(나사 및 오일링의 마찰손실 10% 감안)(Considering 10% friction loss of screws and oil rings)

스프링 모멘트 M : 0.2 kg-m 이상 스프링 사용Spring moment M: 0.2 kg-m or more spring

이상에서 상술한 바와같이 스프링 과 나사를 설치함으로서 소형으로 제작 할수 있을뿐 아니라 제작비가 싸게들며 유압유를 이용하여 문이 천천히 닫히고 또한 이유압유는 스프링의 소음방지는 물론 스프링의 수명을 반영구적으로 할수있으며 문옆으로 설치함으로 미관상에도 좋다.As described above, by installing the spring and screw, not only can be manufactured in a small size, but also the production cost is low, and the door is closed slowly by using hydraulic oil, and the reason pressure oil can semi-permanently prevent the noise of the spring as well as the life of the spring. It is also aesthetically pleasing as it is installed.
