Abstract

본 발명은 도어를 열고난 다음 일부러 닫지 않아도 자동적으로 닫아주고 출입자가 필요에 따라서 도어를 열어 어느 위치에서나 도어를 정지시킬 수 있도록 구성한 유압도어 클로우져에 관한 것이다.The present invention relates to a hydraulic door closer configured to automatically close the door after opening the door, and to allow the accessor to stop the door at any position by opening the door as needed.

종래의 유압도어 클로우져는 약 90°정도의 문을 열었을 경우에는 출입자가 원하지 않은 상태에서도 자동적으로 문이 정지되었으며 출입자가 필요에 따라 도어를 조금 열어 놓고 싶었을 경우 정지 시키기가 어려웠다.The conventional hydraulic door closer is about 90 ° when the door is opened, the door is automatically stopped even if the accessor does not want it, and it was difficult to stop when the person wanted to open the door as needed.

또한 축수부 회전운동에 의한 피스턴의 왕복 직진 운동은 피스턴 내면에 삽설된 스프링을 압축하는 과정에서 실린더내의 측벽 방향으로도 마찰저항이 발생하여 실린더 측벽의 마모가 심하여 사용수명을 짧게 하였으며 실린더 양측면의 마개와 축수부 위와 아래의 마개에서는 오일누수의 원인이 되었다.In addition, the reciprocating straight motion of the piston by the bearing part rotational movement generates frictional resistance in the direction of the side wall of the cylinder in the process of compressing the spring inserted on the inner surface of the piston, which shortens the service life of the cylinder side wall. The plugs above and below the water reservoir can cause oil leakage.

본 발명은 종래의 이와 같은 단점들을 감안하여 문을 자동적으로 닫아주면서 어느 위치에서나 문 출입자의 필요에 따라서 문을 정지시킬 수 있게 문 스톱장치를 구성하고 오일누수의 원인이 되는 마개를 1개로 하였으며 실린더내의 측벽의 마모를 줄이기 위하여 축수부 회전운동에 의하여서 오일이 유동케 하였으며 작동암에 착설한 판 스프링(51)에 의하여 열려진 문이 자동으로 닫아질때에 실린더내의 유동되는오일을 제어하여 문의 회전속도를 증감할 수 있도록 하였다.The present invention has been made in consideration of the disadvantages of the prior art, the door stop device is configured to stop the door according to the needs of the door accessor at any position while automatically closing the door, and one stopper that causes oil leakage is one cylinder In order to reduce abrasion of the inner side wall, oil is flowed by the bearing part rotational movement, and the rotation speed of the door is controlled by controlling the oil flowing in the cylinder when the door opened by the leaf spring 51 installed on the working arm is automatically closed. To increase or decrease.

이와같이 구성되는 본 발명은 실린더(2) 내면 측벽에 오일막이 돌출면(2')을 형성하고 실린더(2)에 삽설되어 회전하는 축수부(13) 외경 축선상에 실린더(2) 내면과 밀착되고 실린더(2) 길이와 같은 오일막이 돌출면(13')을 형성하여서 축수부(13)가 회전하면 실린더(2)내의 충만된 오일이 유동케하여 유압 통로공(39)(40)을 따라 이동되는 오일을 유압이동량 조정봉(33)에 의한 오일의 이동되는 량을 조정하여 문의 회전을 천천히 감속시킬 수 있다.According to the present invention configured as described above, the oil film forms a protruding surface 2 'on the inner side wall of the cylinder 2 and is in close contact with the inner surface of the cylinder 2 on the outer diameter axis of the bearing portion 13 which is inserted into the cylinder 2 and rotates. An oil film equal to the length of the cylinder 2 forms a protruding surface 13 ′, and when the bearing portion 13 rotates, the oil filled in the cylinder 2 flows and moves along the hydraulic passage holes 39 and 40. It is possible to slowly decelerate the rotation of the door by adjusting the amount of oil being moved by the oil movement amount adjusting rod 33.

이와같은 구성은 본 발명의 대표적인 특징으로서 본 발명을 여러 가지 형태로 변형 구성될 수 있고 본 발명의 유압도어클로우져 몸체에는 문스톱 장치를 축수부(13) 하부와 본체(1) 밑면에 걸쳐서 구성 조합시킬 수 있는 바 축수부(13) 하부에 형성한 내경(14)에 압축스프링(20)을 축설한 축봉(93)을 삽입 멈춤링(18')으로 고정시킨다음 고정편(87)에 형성한 볼 통로공(88')에 볼(21)을 삽입 축봉(93)에 형성한 볼 착설홈(17)에 볼(21)을 압착시키며 고정편(87)을 피스나사(96)로 본체(1)에 고정시키고 축봉(93)의 밑면의 삽설공(93')에 삽설된 고리(22)에 끈(23)으로 연결된 손고리(24)를 잡아당기면 볼(21)이 축수부(13) 내면에 각인된 볼고정홈(90')에 고정되어 축수부(13) 회전을 스톱시키므로 문은 어느 위치에서나 스톱시킬 수 있다.Such a configuration is a representative feature of the present invention may be configured in various forms of the present invention and the hydraulic door closer body of the present invention comprises a door stop device over the lower part of the bearing portion 13 and the bottom of the main body (1) The shaft bar 93 having the compression spring 20 arranged in the inner diameter 14 formed at the lower part of the bar bearing part 13 which can be combined is fixed by the insertion stop ring 18 ', and then formed in the fixing piece 87. The ball 21 is squeezed into the ball installation groove 17 formed with the ball 21 into the ball passage hole 88 'and the shaft rod 93, and the fixing piece 87 is fixed with a piece screw 96. 1) and pulls the hand ring 24 connected to the ring 22 inserted into the insertion hole 93 'of the bottom of the shaft 93 by the string 23, and the ball 21 is the bearing portion 13 The door can be stopped at any position because it is fixed to the ball fixing groove 90 'imprinted on the inner surface to stop the rotation of the bearing part 13.

위와 같은 스톱장치의 구성은 코일스프링(20)이 삽설된 축수부(13)의 내경(14)이 작동암에 판스프링(51)을 착설하여 작동되는 축수부(13)의 내경(14)보다 크므로서 볼통로공(88')이 있는 고정편(87)의 축수부(13)에 삽입부분이 두꺼워지므로 볼(21) 대신 핀(89)으로 대용 사용하고 축수부(13)가 스톱된 상태를 해정시키려면 문을 조금 열어 주거나 손고리(24)를 밑으로 당기면 해정된다.The configuration of the stop device as described above is that the inner diameter 14 of the bearing portion 13, in which the coil spring 20 is inserted, than the inner diameter 14 of the bearing portion 13 operated by installing the leaf spring 51 on the operation arm. Since the insertion portion becomes thicker in the bearing portion 13 of the fixing piece 87 having the ball passage hole 88 ', it is used as a pin 89 instead of the ball 21, and the bearing portion 13 is stopped. To release the door a little open or pull the hand ring (24) is released.

위와같이 구성되어 작동되는 본 발명은 종래의 유압도어 클로우져와 비교하여 실린더내에서 축수부의 회전에 의하여 실린더내의 오일이 유동하므로서 유압이동량 조정봉으로 문의 회전 속도를 조정할 수 있을뿐만 아니라 실린더 내면의 측벽의 마모가 거의 없고 구성 부품들의 제작이 쉬워서 가공단가를 낮출수 있으며 또한 축수부 하부 내경과 본체 밑면에 걸쳐서 구성 조합한 문 스톱 장치는 문출입자가 문을 스톱시키고자 할때는 어느 위치에서나 문을 스톱시킬 수 있기 때문에 편리하고 문 하부에 따로 문스톱장치를 설치할 필요가 없기 때문에 문스톱장치 설치 비용이 절감되고 미관상 깨끗하게 문에 부착사용할 수 있는 유압도어 클로져이다.The present invention constructed and operated as described above allows the oil in the cylinder to flow by the rotation of the bearing portion in the cylinder as compared to the conventional hydraulic door closer, so that the rotational speed of the door can be adjusted with the hydraulic movement adjusting rod as well as the side wall of the cylinder inner surface. Almost no wear and easy to manufacture components, reducing the cost of processing, and the door stop device composed of a combination of the inner diameter of the lower part of the bearing portion and the bottom of the body can stop the door at any position when the door to stop the door. Because it is convenient and there is no need to install the door stop device at the bottom of the door, the door stop device installation cost is reduced and it is a hydraulic door closer that can be attached to the door cleanly.
