Description

도어용 플로어 힌지{FLOOR HINGE FOR A DOOR}Floor hinge for door {FLOOR HINGE FOR A DOOR}

본 발명은 도어용 플로어힌지에 관한 것으로, 힌지 몸체의 크기와 부품수를 최소로 줄여 제작을 간편히 하면서도 성능은 크게 향상되는 새로운 구조의 플로어힌지에 관한 것이다.The present invention relates to a floor hinge for a door, and to a floor hinge of a new structure that greatly improves the performance while simplifying the production by reducing the size and number of parts of the hinge body to a minimum.

종래의 일반적인 플로어 힌지는 도어의 개폐작동에 따라서 회전하는 회전축에 편심캠이 일체로 형성되고, 상기한 편심캠은 코일스프링에 받쳐진 수평연결대를 진퇴작동시키는 구조로 되어 있으며, 도어가 열릴 때 편심캠이 수평연결대를 뒤로 밀어서 코일스프링을 압축시키고 도어의 열림작동이 중지되면 그즉시 압축된 코일스프링의 복귀탄성이 작용하여 수평연결대를 전진 이동시켜 회전축을 역회전시킴에 의해서 도어가 닫히게 구성되어 있다.Conventional floor hinge is formed integrally with the eccentric cam on the rotating shaft to rotate according to the opening and closing operation of the door, the eccentric cam has a structure for advancing and retracting the horizontal connecting rod supported by the coil spring, when the door is eccentric When the cam pushes the horizontal connecting rod back to compress the coil spring and the opening operation of the door stops, the return elasticity of the compressed coil spring acts immediately, and the door is closed by moving the horizontal connecting rod forward and rotating the rotating shaft reversely. .

상기한 종래의 구조는 회전축과 연결되는 편심캠과 수평연결대 및 피스턴과 오일밸브 등의 부품이 길게 직선상으로 연결 설치되므로 그 만큼 많은 부품을 내장하기 위한 설치공간이 커야하며, 이 때문에 케이스의 폭과 기장을 줄일 수 없어 각 제조업체에서는 대다수 약간의 구조만 변경할 뿐 길다란 케이스를 사용하여야 하고, 부품수가 많으므로 인해서 제작 및 조립이 힘들고 제작가도 높으며, 사용중에 고장발생율이 크고 수명이 길지 못한 문제점이 있었다.In the conventional structure, since the eccentric cam, the horizontal connecting rod, and the piston and the oil valve, which are connected to the rotating shaft, are installed to be connected in a long straight line, the installation space for embedding many parts should be large. Because the length and length of the product cannot be reduced, each manufacturer has to change the structure of most of them and use a long case, and due to the large number of parts, it is difficult to manufacture and assemble, and the production is high. .

다른 문제점은 회전축의 회전력을 직선 진퇴작동으로 변환하는 방식이므로 각각의 연결 접속부에 대한 작동부하가 많아 부드러운 작동을 기대할 수 없고 항상 힘들게 문을 열어야하는 사용상의 불편점도 있었다.Another problem is the method of converting the rotational force of the rotary shaft into a straight forward and backward operation, so there is a lot of operating load on each connection connection part can not expect smooth operation, there was also the inconvenience in use to always open the door hard.

본 발명의 목적은 상기한 종래의 문제점을 감안해서 도어의 개폐작동에 의해서 연동하는 부품구성원을 최소로 줄이면서도 기능은 향상되고 설치공간을 최소로 하여 케이스의 기장을 줄일 수 있는 새로운 구조의 플로어힌지를 제공하는 것이며,다른 목적은 회전축의 직하 위치에 지랫대 방식의 수직 탄성 가압장치를 설치하여 회전작동을 승강캠에 의해서 민감하게 승강작동으로 전환하여 도어의 부드러운 개폐작동을 수행할 수 있고 제작 및 원가를 줄일 수 있게 하는 것이다.The object of the present invention is a floor hinge of a new structure that can reduce the length of the case by improving the function and minimize the installation space while minimizing the number of components interlocked by the opening and closing operation of the door in view of the above-mentioned conventional problems. Another object is to install a vertical elastic pressing device of the belt type in the position directly below the rotating shaft to switch the rotation operation to the lifting operation sensitively by the lifting cam to perform the smooth opening and closing operation of the door and It is to reduce the cost.

상기한 목적을 달성하기 위해서 본 발명은 도어와 연결되어 도어의 개폐작동에 의해서 좌우 회전하는 회전축에 관체형의 승강캠을 끼워서 회전축의 좌우회전에 따라서 상승 또는 하강하게 하고 승강캠에는 지랫대형의 가압대를 연결하여 함께 승강작동되게 하며 승강캠은 그 하부의 원추형 압축코일스프링에 의해서 상승 복귀력을 갖게 하고 가압대는 급상승억제장치에 의해서 서서히 상승할 수 있게 구성한 것을 특징으로 한 것이다.In order to achieve the above object, the present invention is connected to the door by inserting a tubular lifting cam on the rotary shaft to rotate left and right by the opening and closing operation of the door to raise or lower according to the left and right rotation of the rotary shaft and pressurizes the large cam to the lifting cam It is characterized in that the lifting cam has a lifting return force by the conical compression coil spring at the bottom thereof, and the pressure bar is configured to be gradually lifted by the sharp lifting suppression device.

하부케이스(1)의 중간에 가압핀(3)을 일체로 가진 회전축(2)을 수직상으로 입설하고 회전축(2)에 정지홈(4)을 중심으로 하여 양쪽으로 경사면(5)을 가진 관체형 캠(6)을 승강 가능하게 결합하여 상면의 경사면(5)은 회전축의 가압핀(3)에 의해서 눌려지게 하고 하단부는 원추형 코일스프링(7)에 받쳐지게 설치하며, 일측이 고정편(8)에 힌지식으로 결속된 가압대(10)의 중간을 캠(6)의 측면에 핀(9)으로 체결하여 캠(6)과 함께 승강작동되게 하고, 가압대(10)의 외단부를 뚜껑(11)에 고정된 압력제어실린더(12)의 하단부에 접속되게 하여 상승탄력이 억제되게 구성한 것이다.A tube having a rotary shaft (2) integrally equipped with a pressing pin (3) in the middle of the lower case (1) vertically and having an inclined surface (5) on both sides around the stop groove (4) on the rotary shaft (2). Combining the body cam 6 so as to be able to lift and lower so that the inclined surface (5) of the upper surface is pressed by the pressing pin (3) of the rotary shaft and the lower end is installed to be supported by the conical coil spring (7), one side of the fixing piece (8) The middle of the press table (10) hinged to the side of the cam (6) by fastening the pin (9) to the side of the cam (6) to move up and down with the cam (6), the outer end of the press table (10) It is configured to be connected to the lower end of the pressure control cylinder 12 fixed to 11 so that the rising elasticity is suppressed.

상기한 압력제어실린더(12)는 뚜껑에 고정된 본체(13)의 내측 공간에 약성 코일스프링(14)과 오일이 내장되어 승강캡(15)의 급속한 상승압력을 탄력적으로 완화시킬 수 있게 하는 완충구 작용을 하는 것이며, 본체 일측에는 오일밸브(16)를 설치하여 필요시 외부에서 조절나사로 오일의 유통량을 조절하게 구성한 것이다.The pressure control cylinder 12 has a damping coil spring 14 and oil built into the inner space of the main body 13 fixed to the lid to cushion the rising pressure of the elevating cap 15 elastically. It is to function, and the oil valve 16 is installed on one side of the main body is configured to adjust the flow rate of the oil with an adjustment screw from the outside if necessary.

상기한 원추형 코일스프링(7)은 고강력 탄성을 가진 것이고, 이에 비해서 압력제어실린더(12)의 코일스프링(14)은 탄성이 약한 것을 사용하며, 압력제어실린더 (12)는 도어(A)가 열릴 때는 가압대(10)의 하향 가압력을 보강하여 가볍게 열리게 하는 반면에 도어(A)가 닫힐 때는 가압대(10)의 상승 복귀력을 억제하여 도어(A)가 최종지점에서 천천히 닫히게 하는 작용을 하는 것이며, 케이스의 내부에는 오일을 주입한 상태로 뚜껑을 밀봉하여 각 구동부의 윤활성을 유지하게 한 것이다.The conical coil spring 7 has a high strength elasticity, whereas the coil spring 14 of the pressure control cylinder 12 uses a weak elasticity, and the pressure control cylinder 12 has a door A When opened, it reinforces the downward pressing force of the presser 10 so that it is opened lightly, whereas when the door A is closed, it restrains the upward return force of the presser 10 so that the door A is slowly closed at the final point. The inside of the case is to seal the lid in the state injecting oil to maintain the lubricity of each drive unit.

이와 같이 구성된 본 발명은 통상의 플로어힌지와 동일한 방법으로 시공 설치하는바, 미 도시된 별도의 외부케이스에 밀봉한 상태로 도어의 하부에 매설하고 회전축(2)의 상부 접속편을 도어(A) 하단부의 접속홈에 연결 조립하여 사용한다.The present invention configured as described above is installed in the same manner as a conventional floor hinge bar, embedded in the lower portion of the door in a sealed state in a separate outer case not shown and the upper connection piece of the rotating shaft (2) to the door (A) It is used by connecting it to the connection groove of the lower part.

본 발명은 도2 및 도5와 같이 도어(A)가 닫힌 상태에서는 캠(6)과 가압대(10)가 상승된 상태로서, 이때는 가압대(10)의 외단부가 원추형 코일스프링 (7)의 상향 탄동력에 의해서 압력제어실린더(12)의 승강캡(15)을 상승(압축)시킨 상태를 유지한다.2 and 5, the cam 6 and the presser 10 are lifted in the state in which the door A is closed, and at this time, the outer end of the presser 10 is conical coil spring 7. The state in which the lifting cap 15 of the pressure control cylinder 12 is raised (compressed) by the upward elastic force of.

이 상태에서 출입자가 도어(A)를 밀어서 열어주면 도3 및 도6과 같이 회전축 (2)이 회동하고, 함께 회동하는 가압핀(3)은 캠(6)의 경사면(5)을 가압하여 하강시키므로 결국은 캠(6)에 결속된 가압대(10)도 함께 하강하게 되며, 캠(6)은 그 하방의 원추형 코일스프링(7)을 압축시키면서 하강하는 것이다.In this state, when the person pushes the door A to open it, the rotating shaft 2 rotates as shown in FIGS. 3 and 6, and the pressing pin 3 which rotates together presses and lowers the inclined surface 5 of the cam 6. As a result, the press table 10 attached to the cam 6 is also lowered, and the cam 6 is lowered while compressing the conical coil spring 7 below.

특히 도6과 같이 도어(A)가 90도 각도로 회동하여 열리면 가압핀(3)이 캠의 정지홈(4)에 떨어져 고정되므로 이때부터는 도어가 임의로 닫히지 않고 열린 상태를 유지하며, 열려진 도어를 닫을 때는 인위적으로 도어를 당겨서 닫아주면 압축된 원추형 코일스프링(7)의 복원력에 의해서 캠(6)과 가압대(10)가 상승하면서 닫힘 방향으로 회전하는 회전축(2)과 도어의 회전력에 탄력을 부여하여 정확한 닫힘 작동이 이루어지게 하는 것이다.In particular, when the door A is rotated and opened at an angle of 90 degrees, as shown in FIG. 6, the pressing pin 3 is fixed to the stop groove 4 of the cam, so that the door is kept open without being arbitrarily closed. When closing, by artificially pulling the door closed, the cam 6 and the presser 10 are raised by the restoring force of the compressed conical coil spring 7, and the rotary shaft 2 rotates in the closing direction and the rotational force of the door is elastic. To ensure that the correct closing operation is achieved.

또한 도어를 90도 각도로 완전히 열어 놓지 않고, 평시의 출입 가능한 범위내에서 도어를 개폐할 때는 상기한 원추형 코일스프링(7)에 의해서 탄력적으로 도어의 열리고 닫히는 작동이 반복되는 것이다.In addition, when the door is opened and closed within the usual allowable range without opening the door completely at an angle of 90 degrees, the operation of opening and closing the door elastically by the conical coil spring 7 is repeated.

상기한 작동 과정에서 압력제어실린더(12)는 가압대(10)가 상승작동할 때 (도어 닫힘)는 압축되어 가압대(10)의 상승압력을 점차적으로 억제하므로서 도어가 최종 닫힘 단계에서 천천히 닫히게 하는 작동을 하고, 이와는 반대로 가압대(10)가 하강작동할 때(도어 열림)는 압축되어 있던 압력제어실린더(12)의 탄동 복귀력이 가압대(10)를 밑으로 눌러서 하강력을 돕게되므로 도어가 가볍고 부드럽게 열릴 수 있는 것이다.In the above operation process, the pressure control cylinder 12 causes the door to be slowly closed in the final closing step by gradually suppressing the upward pressure of the presser 10 when the presser 10 is lifted up (door closing). On the contrary, when the presser 10 lowers (doors open), the elastic return force of the compressed pressure control cylinder 12 assists the presser 10 by pushing down the presser 10. The door can be opened lightly and smoothly.

압력제어실린더(12)는 코일스프링(14)의 탄동력과 오일압력이 작용하므로 승강캡(15)의 급속한 승강작동은 제어되고 천천히 승강 작동되게 하는 것이며, 승강캡이 가압되어 상승할 때는 내측의 오일압력이 오일밸브(16)를 통해서 토출되면서 상승압력을 서서히 제어하는 작용을 하고, 이와 반대로 승강캡이 복귀될때는 내부에 흡인력이 작용하여 외부의 오일이 체크밸브로 흡입되면서 하강하는 것이다.In the pressure control cylinder 12, the elastic force and the oil pressure of the coil spring 14 act so that the rapid elevating operation of the elevating cap 15 is controlled and slowly elevating operation, and when the elevating cap is pressurized and raised, As the oil pressure is discharged through the oil valve 16, the rising pressure is gradually controlled. On the contrary, when the lifting cap is returned, the suction force acts on the inside to lower the oil while being sucked into the check valve.

본 발명은 회전축의 하부에 캠(6)과 가압대(10) 및 원추형 코일스프링(7)을 수직상으로 배열 설치하여 도어와 연결된 회전축의 회전작동을 수직 승강작동으로 전환하여 압력이 제어되게 구성하므로서 각 접속부에 대한 작동부하를 줄이면서 부드럽고 원활한 개폐작동을 수행할 수 있다.The present invention is installed so that the cam 6 and the presser 10 and the conical coil spring 7 arranged in a vertical position in the lower portion of the rotating shaft to switch the rotation operation of the rotating shaft connected to the door to the vertical lifting operation to control the pressure Thus, smooth and smooth opening and closing operation can be performed while reducing the operating load on each connection part.

또한 종래 길다란 원통형 코일스프링을 횡방향으로 길게 뉘어서 설치하던 것에 비해서 본 발명은 원추형 코일스프링을 회전축의 하방에 수직상으로 설치하므로서 별도의 설치공간이 필요 없이 좁은 공간에 간편히 설치할 수 있어 케이스의 기장과 부피를 최소로 줄이면서도 기능은 향상되고 부품수를 줄여서 제작성, 조립성 및 상품성을 높일 수 있는 효과가 있다.In addition, the present invention compared to the conventional long elongated cylindrical coil spring in the transverse direction to install the conical coil spring vertically below the axis of rotation, so it can be easily installed in a narrow space without the need for a separate installation space of the case and Functionality is improved while the volume is minimized, and the number of parts can be reduced, thereby increasing the manufacturability, assemblability and commerciality.
