Description

도어충격완충장치{Door Damper}Door Shock Absorber {Door Damper}

본 고안은 도어충격완충장치에 관한 것으로, 가정에서 가구나 싱크대의 도어를 빠르게 여닫을 때 도어가 도어틀에 부딪혀 발생되는 충격과 이에 따른 소음을방지하기 위한 도어충격완충장치에 관한 것이다.The present invention relates to a door shock absorber, and to a door shock absorber for preventing the impact and noise caused by the door hit the door frame when opening and closing the door of the furniture or sink at home quickly.

일반적으로 가정의 옷장, 책꽂이 등과 같은 가구나 싱크대에는 스프링힌지에 의해 도어가 부착되며, 이러한 도어를 개폐함에 있어서, 특히 도어를 열 때 보다는 닫을 때에, 서서히 닫을 때에는 괜찮겠지만 급작스럽게 닫을 경우에는 도어가 도어틀에 부딛혀서 심한 충격이 가해지고, 그 충격으로 인해 소음이 발생하며, 심할 경우에는 도어가 파손되는 경우도 있다.Generally, doors are attached to furniture or sinks such as closets and bookshelves in homes by spring hinges, and when opening or closing such doors, especially when closing the door, it is fine to close it slowly, but if the door is closed suddenly, Severe impacts are applied to the frame, noises are generated by the impacts, and in some cases doors can be broken.

또한 도어를 급작스럽게 닫을 때 도어틀과 도어 사이에 손가락이 끼여 부상을 당하게 되는 경우도 발생하게 된다. 특히 어린 아이들의 경우에는 가구나 싱크대 등의 도어를 부주의하게 닫는 경우가 많아서 상기한 문제가 더욱 많이 발생하게 된다.In addition, when the door is suddenly closed, a finger may be caught between the door frame and the door, resulting in injury. In particular, children often inadvertently close doors such as furniture or sinks, which causes more problems.

이러한 문제점을 해결하기 위해서 종래에는 도 1과 같은 도어충격완충장치가 개발되어 있다. 그러나, 종래의 도어충격완충장치는 스프링힌지에 의해 설치된 도어가 급작스럽게 닫힐 경우에는 도어가 범퍼(13)에 닿을 때 튀는 현상과 함께 소음이 발생되며, 제1,2체크밸브(21,22)를 통해서 지나가는 오일의 유로가 협소하여 오일챔버내의 압력이 과도하게 상승되고, 이러한 압력상승으로 인해 오일챔버(3)를 둘러싸고 있던 하우징이 외부로 휘게 되어 오일의 유출을 막고 있던 오일시일(17)과 하우징본체(16) 사이에 미세한 틈이 발생하게 되어 오일이 유출되는 경우가 발생하고, 상기 도어는 스프링힌지에 의해 설치되기 때문에 탄성이 약한 복귀스프링(15)을 사용해야 하는데, 이렇게 할 경우 복귀되는 속도가 느린 문제점이 있었다.In order to solve this problem, a door shock absorber as shown in FIG. 1 has been developed. However, in the conventional door impact buffer device, when the door installed by the spring hinge is suddenly closed, noise is generated when the door touches the bumper 13, and noise is generated, and the first and second check valves 21 and 22 are provided. The flow path of the oil passing through the narrow narrow pressure in the oil chamber excessively, due to this pressure rise the housing surrounding the oil chamber (3) is bent to the outside and the oil seal (17) that prevented the outflow of oil and A fine gap is generated between the housing main body 16 and oil leaks out, and since the door is installed by a spring hinge, it is necessary to use a return spring 15 having weak elasticity. There was a slow issue.

상기한 문제점들을 해결하기 위해서 본 고안의 목적은 일반적인 형태의 도어충격완충장치에서 충격을 잘 흡수할 수 있음과 동시에 유로를 넓게 형성시켜 오일챔버내의 복귀스프링의 강도가 약해도 쉽게 복귀될 수 있는 도어충격완충장치를 제공함에 있다.In order to solve the above problems, an object of the present invention is to absorb shocks in a general type of door shock absorber and to form a wide flow path so that the door can be easily returned even if the strength of the return spring in the oil chamber is weak. An impact buffer device is provided.

이때 도어(16)를 열게되면 스프링(130)에 의해서 도 2과 같이 피스톤로드(40)가 전방으로 전진하여 상기 범퍼고정캡(30)의 플랜지부(31)와 공간가이드부시(50)의 내부플랜지부(53)와 맞닿는 위치에서 멈추게 된다.In this case, when the door 16 is opened, the piston rod 40 is advanced forward by the spring 130 as shown in FIG. 2, so that the flange portion 31 and the space guide bush 50 of the bumper fixing cap 30 are opened. It stops at the position which abuts the flange part 53. As shown in FIG.

상기와 같이 도어(16)가 닫히는 경우와 열리는 경우의 오일경로를 나누어서 설명할 수 있는데, 이를 설명하면 다음과 같다.As described above, it can be described by dividing the oil path when the door 16 is closed and when opened, which will be described as follows.

1. 도어가 서서히 닫히는 경우1. The door closes slowly

피스톤로드(40)가 도어(16)에 의해서 서서히 후방으로 밀릴 때 오일챔버(110) 내의 오일은 도 10의 A의 경우와 같이 제1,2체크밸브(210,200)의 외주연과 내부 중앙을 지나서 AA부분과 BB부분을 통해서 이동하게 된다.When the piston rod 40 is slowly pushed backward by the door 16, the oil in the oil chamber 110 passes through the outer periphery and the inner center of the first and second check valves 210 and 200, as in the case of A of FIG. 10. It moves through AA and BB.

2. 도어가 급작스럽게 닫히는 경우2. The door closes suddenly

피스톤로드(40)가 도어(16)에 의해서 급작스럽게 후방으로 밀릴 때에는 오일챔버(110) 내의 오일은 도 10의 B의 경우와 같이 큰 압력으로 제2체크밸브(200)를 누르게 되어 실린더가이드(220)의 수용홈에 상기 돌출부가 들어가 중앙에 밀착되고, 상기 제2체크밸브(200)의 플랜지부는 순간적으로 외주연으로 휘게 된다. 즉, 도 10의 B와 같이 제2체크밸브(200)가 AA부분을 막게 되어 오일은 BB부분만으로 이동됨으로써 충격을 흡수할 수 있다.When the piston rod 40 is suddenly pushed backward by the door 16, the oil in the oil chamber 110 presses the second check valve 200 at a large pressure as in the case of B of FIG. The protruding portion enters the receiving groove of the 220 and is in close contact with the center thereof, and the flange portion of the second check valve 200 is instantaneously bent to the outer circumference. That is, as shown in B of FIG. 10, the second check valve 200 blocks the AA part, so that the oil may be moved to the BB part alone to absorb the shock.

상기 2의 경우에는 오일의 흐름을 제어해줌으로, 즉 오일이 흐르는 양을 조절해 줌으로써 도어로부터 오는 충격을 흡수해주고, 상기 오일의 흐름을 제어할 때 제2체크밸브(200)에 의해 유로가 부드럽게 형성되어, 상기 오일챔버(110) 내의 압력이 과다하게 축척되지 않는다.In the case of 2, by controlling the flow of oil, that is, by adjusting the amount of flow of oil absorbs the shock from the door, when controlling the flow of oil smoothly flow path by the second check valve (200) Formed, the pressure in the oil chamber 110 is not excessively accumulated.

3. 도어가 열리는 경우3. The door opens

피스톤로드(40)가 도어(16)에 의해서 전방으로 복귀될 때에는 오일챔버(110) 내의 오일은 도 10의 C의 경우와 같이 AA부분과 BB부분을 통해서 제1체크밸브의 중앙과 외주연 및 제2체크밸브(200)의 내부 중앙을 지나 이동하게 된다.When the piston rod 40 is returned to the front by the door 16, the oil in the oil chamber 110 passes through the AA part and the BB part as in the case of C of FIG. The second check valve 200 is moved past the inner center.

상기한 것과 같이 본 고안의 도어충격완충장치에 의하면, 충격을 잘 흡수할 수 있음과 동시에 유로를 넓게 형성시켜 오일챔버내의 복귀스프링의 강도가 약해도 쉽게 복귀될 수 있는 효과가 있다.As described above, according to the door shock absorber of the present invention, it is possible to absorb shocks and at the same time, the flow path is formed wide so that the return spring in the oil chamber can be easily recovered even if the strength of the return spring is weak.
