본 고안은 회전원판에 대향으로 형성한 한쌍의 호형곡선캠을 이용하여 피스턴과 연결된 연결편의 연결부에서 관절작동되어 피스턴을 상승 또는 하강시키므로서 실린더내에 일정량으로 들어 있는 오일을 피스턴의 상,하부로 유동시킬 때 완충작용을 할 수 있게한 유압작동 완충경첩에 관한 것이다.The present invention uses a pair of arc-curve cams formed opposite to the rotating disk to articulate at the connection part of the connecting piece connected to the piston to raise or lower the piston, thereby flowing oil contained in a certain amount into the cylinder up and down. It relates to a hydraulically actuated shock absorbing hinge that allows the shock absorber to act upon.

종래의 경첩은 대부분 문틀과 문짝을 연결시켜 문짝을 여닫을 수 있게 연결해주는데 그쳤고 문짝이 자동으로 닫히면서도 서서히 닫히도록 하는 완충장치는 경첩과는 전혀 별개로한 도어크로저와 같은 것을 문틀과 문짝의 상부에 설치하여 완충작용을 하게하는 것이 보통이나, 이는 구조가 복잡하여 고장율이 많을 뿐 아니라 설치장소에 구애를 받게되고 설치된 완충장치가 외부로 노출되어 미관상 좋지못한 문제점들이 있었다.Conventional hinges mostly connect door frames and doors so that doors can be opened and closed. Shock absorbers, which allow the doors to close automatically and slowly close, are the same as door closers that are completely independent of the hinges. It is common to install in the buffer, but this is not only a complicated structure, but also a high rate of failure as well as a lot of installation place and the installed shock absorber is exposed to the outside there were aesthetic problems.

이와같은 문제점을 적게하기 위하여, 본 고안은 하부에 유로가 형성된 실린더 내에 설치된 피스턴에 연결시킨 연결편을 피스턴상부에 수평안내핀에 의하여 수평 이동되게 설치된 좌,우 이동핀과 연결시키고 좌,우 이동핀은 회전축에 의하여 좌,우 회전 되는 회전원판에 대향으로 형성한 한쌍의 호형곡선캠에 끼워설치하고 상,하부에 코일스프링을 설치한 실린더내에 일정량의 오일을 유입시켜서된 것으로 문틀과 문짝에 연결되게 설치하여 문짝의 개폐시 회전축의 회전에 따라 회전되는 회전원판에 형성된 한쌍의 호형곡선에 따라 좌,우 이동핀이 벌어지거나 좁혀저서 피스턴을 상,하 왕복운동시킬때 실린더내의 오일이 유로와 피스턴에 설치한 개폐벨브와 채크밸브에 의하여 피스턴의 상,하로 이동하게 되는데 이때 인위적으로 문짝을 열때는 피스턴이 상승하면서 오일은 피스턴 하부로 이동되어 있다가 코일스프링의 탄발력에 의하여 문짝이 닫힐때는 회전축이 회전하면서 회전원판을 회전시키므로 회전원판에 형성된 호형곡선캠에 따라 좌,우 이동핀이 원심방향으로 좁혀지면서 연결편에 의하여 피스턴이 하강하여 오일이 유로와 채크밸브를 통하여 피스턴상부에 이동되면서 문짝은 유압에 의하여 서서히 닫히다가 다른 유로가 열리면서 빠른속도로 닫히는 동안에 채크밸브가 열리면서 닫히는 속도가 더욱 빨라저서 문짝을 완전하게 닫히게 한 것이다.In order to reduce the above problems, the present invention connects the connecting piece connected to the piston installed in the cylinder formed with the flow path at the lower part with the left and right moving pins installed to be horizontally moved by the horizontal guide pins on the piston. Is inserted into a pair of arc-shaped curved cams formed opposite to the rotating disk rotated left and right by the rotating shaft, and a certain amount of oil is introduced into the cylinder where the coil spring is installed on the upper and lower sides. When the door is opened and closed, the oil in the cylinder flows to the flow path and piston when the left and right moving pins are reciprocated or narrowed according to a pair of arc curves formed on the rotating disc which rotates according to the rotation of the rotating shaft. The piston is moved up and down by the opening / closing valve and the check valve installed. When opening the door artificially, the piston When the oil is moved to the lower part of the piston while the door is closed due to the elastic force of the coil spring, the rotating shaft rotates and rotates the rotating disk, so the left and right moving pins move in the centrifugal direction according to the arc curved cam formed on the rotating disk. As the piston is lowered by the connecting piece and the oil is moved to the upper part of the piston through the flow path and the check valve, the door is slowly closed by hydraulic pressure, and the check valve opens and closes faster while the other flow path is closed at a high speed. To close completely.

이상과 같이된 본 고안을 첨부도면에 의하여 상세히 설명하면 다음과 같다. 일측 연결편(1)과 단일체로 형성된 실린더(2)내에 개폐벨브(3)와 수개의 채크밸브(3a)(3b)(3c)를 형성한 피스턴(4)를 설치하고 피스턴(4)상부에는 수평안내핀(5)에 좌,우 이동핀(6)(6a)을 끼워 설치하여 피스턴(4)의 상면 중앙부와 연결편(7)(7a)으로 연결부가 관절되게 연결하고 좌,우 이동핀(6)(6a)은 회전원판(8)에 대향으로 형성된 한쌍의 호형곡선캠(9)(9a)에 끼워 설치하며, 회전원판(8)의 상면에 돌출된 돌기(10)(10a)를 회전축(11)의 단부에 형성된 원판(11a)에 돌출되게 형성한 삽입공(12)(12a)에 끼워 설치하고, 실린더(2)의 하부에는 유로(13)(13a)를 형성하되 유로(13)와 연통되게 개폐밸브(14)를 설치하고 유로(13)와 연통되게 뚫은 오일주입구에는 유량조절밸브(14a)를 설치한다. 타측 연결편(1a)의 양단에 단일체로 형성한 캡(15)(15a)을 실린더(2)의 상부와 하부에서 관형너트(16)(16a)로 지지시키고 각 캡(15)(15a)의 내부에는 코일스프링(17)(17a)을 설치하여 일단은 실린더(2)와 나합 고정된 관형너트(16)(16a)에 고정시키고 타단을 캡(15)(15a)의 상단에 고정시킨 스프링 강도조절해드(18)(18a)에 고정하며, 회전축(11)의 상단은 스프링 강도조절해드(18)에 삽입시켜 보울트(19)로 고정하여서 된 것이다.When described in detail by the accompanying drawings of the present invention as described above are as follows. A piston (4) having an opening / closing valve (3) and several check valves (3a) (3b) (3c) is provided in one connecting piece (1) and a cylinder (2) formed in a single body, and horizontally above the piston (4). Left and right moving pins (6) (6a) are fitted to the guide pin (5) to connect the connecting portion jointly with the upper center of the piston 4 and the connecting piece (7) (7a) and the left and right moving pins (6). (6a) is fitted to a pair of arc-shaped curved cam (9) (9a) formed opposite to the rotating disk (8), the projection (10, 10a) protruding on the upper surface of the rotating disk (8) the rotating shaft ( 11 is inserted into the insertion hole 12 (12a) formed to protrude into the disc (11a) formed at the end of the end 11, the flow path 13 and 13a is formed in the lower portion of the cylinder (2) An on-off valve 14 is provided to communicate with each other, and a flow control valve 14a is installed at an oil inlet drilled to communicate with the flow path 13. Caps 15 and 15a formed in one piece at both ends of the other side connecting piece 1a are supported by tubular nuts 16 and 16a at the upper and lower portions of the cylinder 2, and inside the respective caps 15 and 15a. The spring is adjusted to fix the coil springs (17) and (17a) at one end to the cylinder (2) and the tubular nut (16) (16a), which are fixed together with the screw, and the other end at the top of the cap (15) (15a). It is fixed to the head (18) (18a), the upper end of the rotating shaft 11 is to be inserted into the spring strength adjustment head 18 to be fixed by the bolt 19.

이상과 같이 된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention made as described above are as follows.

연결편(1)(1a)을 문짝과 문틀에 고정시키고 문짝을 열개되면 연결편(1a)의 양단부에 단일체로 형성한 캡(15)(15a)에 설치된 스프링 강도조절해드(18)(18a)가 같이 따라 회전하게되어 코일스프링(17)(17a)이 감기게되고 스프링 강도조절해드(18)(18a)에 고정시킨 회전축(11)이 따라서 회전하게 된다. 이와같이 회전하는 회전축(11)의 하단에 형성된 회전원판(11a)에 돌출되게 형성한 삽입공(12)(12a)에 회전원판(8)의 상면에 돌출된 돌기(10)(10a)가 끼워져 설치되어 있어 회전원판(8)도 따라서 회전하게 된다.When the connecting piece (1) (1a) is fixed to the door and the door frame and the door is opened, the spring strength adjusting heads (18) and (18a) installed on the caps (15) and (15a) formed at both ends of the connecting piece (1a) as a unitary body together. Coil springs (17) (17a) is wound along the rotating shaft 11 fixed to the spring strength adjustment head (18) (18a) is rotated accordingly. The protrusions 10 and 10a protruding from the upper surface of the rotation disc 8 are inserted into the insertion holes 12 and 12a protruding from the rotation disc 11a formed at the lower end of the rotating shaft 11. The rotating disc 8 also rotates accordingly.

이때 회전원판(8)에 대향으로 형성한 한쌍의 호형곡선캠(9)(9a)에 피스턴(4)상부에서 수평안내핀(5)에 이동되게 끼워 설치된 좌,우 이동핀(6)(6a)이 끼워 설치되어 있어 회전원판(8)의 회전방향에 따라 한쌍의 곡선캠(9)(9a)에 안내되어 좌,우 이동핀(6)(6a)은 실린더(2)의 원주방향으로 수평안내핀(5)을 타고 벌어지게 된다.At this time, the left and right moving pins 6 and 6a installed on the pair of arc-shaped curved cams 9 and 9a opposed to the rotating disc 8 so as to be moved to the horizontal guide pins 5 above the piston 4. ) Is installed and guided to a pair of curved cams (9) (9a) according to the rotational direction of the rotary disk (8) so that the left and right moving pins (6) (6a) are horizontal in the circumferential direction of the cylinder (2). The guide pin (5) is to be opened by the.

이와같이 이동되는 좌,우 이동핀(6)(6a)은 실린더(2)내에 설치된 피스턴(4)과 연결편(7)(7a)으로 연결부에서 관절되게 연결되어 있기 때문에 좌,우 이동핀(6)(6a)이 제1도에서와 같이 벌어질때는 연결편(7)(7a)에 의하여 연결부에서 관절되면서 피스턴(4)은 상승하게 된다.The left and right moving pins 6 and 6a moved in this way are jointly connected at the connecting portion with the piston 4 and the connecting pieces 7 and 7a installed in the cylinder 2, so that the left and right moving pins 6 are moved. When 6a is opened as in FIG. 1, the piston 4 is raised while being articulated at the connecting portion by the connecting pieces 7 and 7a.

위에서와 같이 피스턴(4)이 상승할때는 피스턴(4)상부에 유입되어 있던 오일이 유로(13)와 유로에 설치한 개폐밸브(14)와 그리고 피스턴(4)에 설치한 개폐밸브(3)를 통하여 피스턴(4) 하부로 이동되는데 유로(13)에 개폐밸브(14)를 설치하므로 많은량의 오일을 짧은 시간에 이동시킬 수 있어 문짝이 유연하게 열리게 된다.When the piston 4 rises as described above, the oil flowing in the upper portion of the piston 4 flows through the flow path 13 and the on-off valve 14 installed in the flow path and the on-off valve 3 installed on the piston 4. It moves to the lower portion of the piston 4 through the opening and closing valve 14 is installed in the flow path 13, so that a large amount of oil can be moved in a short time, the door is opened flexibly.

그리고 문짝이 닫힐때는 감겨있던 코일스프링(17)(17a)의 탄발력에 의하여 반대방향으로 회전하면서 빠른속도로 닫히려 하나 피스턴 하부에 들어 있는 유압의 저항을 받아 서서히 닫이게 된다.When the door is closed, the coil spring (17) (17a) is closed by a resilient force to rotate in the opposite direction to close at a high speed, but is closed slowly by the resistance of the hydraulic pressure contained in the lower piston.

여기서에서 스프링 강도조절해드(18)(18a)를 좌우로 회전시켜 고정시키게 되면 코일스프링(17)(17a)의 강도를 조절할 수 있어 문짝을 유연하게 닫히도록 할 수 있다.In this case, when the spring strength adjusting heads 18 and 18a are fixed by rotating left and right, the strength of the coil springs 17 and 17a can be adjusted so that the door can be closed flexibly.

이와같이 코일 스프링(17)(17a)의 탄발력에 의하여 문짝이 닫힐때 스프링 강도조절해드(18)(18a)에 고정시킨 회전축(11)이 따라서 회전하게 되므로 회전원판(8)이 회전하게 되어 회전원판(8)에 대향으로 형성한 한쌍의 호형곡선캠(9)(9a)에 끼워 설치된 좌,우 이동핀(6)(6a)이 수평안내핀(5)을 따라 수평을 유지하면서 제2도에서와 같이 원심방향으로 좁혀진다. 이와같이 좌,우 이동핀(6)(6a)이 좁혀지게되면 연결편(7)(7a)으로 연결된 피스턴(4)는 하강하게 되는데 이때 개폐밸브(3)(3a)와 채크밸브(3a)(3b)(3c)가 닫혀있어 오일은 유로(13)를 통하여 피스턴상브로 이동하게 되므로 문짝은 서서히 닫히게 된다.In this way, when the door is closed by the elastic force of the coil springs 17 and 17a, the rotating shaft 11 fixed to the spring strength adjusting heads 18 and 18a rotates accordingly, so that the rotating disc 8 rotates and rotates. The left and right moving pins 6 and 6a, which are fitted to the pair of arc-shaped curved cams 9 and 9a formed opposite to the disc 8, are kept horizontal along the horizontal guide pins 5, respectively. It is narrowed in the centrifugal direction as in. When the left and right moving pins 6 and 6a are narrowed in this way, the piston 4 connected to the connecting pieces 7 and 7a is lowered. At this time, the shut-off valves 3 and 3a and the check valves 3a and 3b are lowered. (3c) is closed so that the oil moves to the piston top through the flow path 13, the door is closed slowly.

여기에서 유량조절밸브(14)를 조절하여 이동유량을 조절할 수 있어 문짝이 닫히는 속도를 자유롭게 조정할 수 있으며, 위에서와 같이 문짝이 닫히고 있다가 실린더(2)에 형성된 유로(13a)가 열리게 되면 많은량의 오일이 이동되어 문짝은 빠른속도로 닫히게 된다.Here, the flow rate can be adjusted by adjusting the flow regulating valve 14 so that the speed at which the door is closed can be freely adjusted. When the door is closed, the flow path 13a formed in the cylinder 2 is opened as described above. Oil is moved and the door closes at high speed.

이때 피스턴(4)에 설치한 채크밸브(3a)(3b)(3c)들이 실린더(2)의 바닥에 순차적으로 닿아 열리게 되어 많은량의 오일이 상승되어 문짝은 더욱 빠른속도로 닫히면서 문틀과 문짝에 설치한 장금장치에 잠기게 된다.At this time, the check valves 3a, 3b, and 3c installed on the piston 4 sequentially open to the bottom of the cylinder 2, so that a large amount of oil is raised, and the door is closed at a faster speed, and the door frame and the door are closed. It will be locked to the locking device installed on it.

이상에서와 같이 본 고안은 문짝을 인위적으로 열을때 많음힘을 들이지 않고 열을 수 있는 동시에 문짝이 닫힐때는 유압에 의하여 완충이 이루어저 서서히 닫히다가 일정시간이 지나면 순간적으로 가속이 붙어 장금장치에 감길 수 있게하는 동시에 이동유량과 스프링의 강도를 자유롭게 조절할 수 있는 이점이 있는 것이다.As described above, the present invention can open the door artificially without any effort and at the same time, when the door is closed, it is buffered by hydraulic pressure, and then slowly closes, and after a certain time, the momentary acceleration is applied to the locking device. At the same time, it is possible to freely adjust the flow rate and strength of the spring.
