Abstract
본 고안은 회전식 도어에 있어서 도어가 열리고 닫힐때 원활한 동작을 할수 있도록 하기 위한 도어의 회전력 제어구조에 관한 고안이다.The present invention is a device for the rotational force control structure of the door to enable a smooth operation when the door is opened and closed in the rotary door.
본 고안 도어의 회전력 제어구조는 도어힌지에 장착되는 캠이 도어가 열리면서 회전될 때는 상하 이동판에 연결된 롯드를 당겨서 도어가 가볍게 열리도록 하고 도어가 닫힐때는 점차 회전력이 저하되면서 천천히 닫히도록 하기 위하여 압축피스톤에 고정된 이동영구자석이 황동부재 내로 출입될 때 마찰자기력이 발생되게 했으며 이동영구자석의 반대쪽에는 고정영구자석을 장착하여 반발차기력에 의하여 압축피스톤이 천천히 이동되게 하는 것이다.The rotational force control structure of the door of the present invention is compressed so that the door is opened lightly by pulling the rod connected to the up and down moving plate when the cam mounted on the door hinge is rotated while the door is opened. Friction magnetic force is generated when the moving permanent magnet fixed to the piston enters and exits the brass member, and the fixed permanent magnet is mounted on the opposite side of the moving permanent magnet so that the compression piston moves slowly by the repulsion kicking force.
Description
본 고안은 힌지를 축으로 회전되면서 개폐되는 도어의 회전력 제어구조에 관한 고안이다.The present invention is an invention related to the rotational force control structure of the door that opens and closes while the hinge rotates about the axis.
회전식 도어는 도어의 일측 상하에 축설되는 힌지를 축으로 회전되며 도어가 열릴때는 사람의 힘에 의하여 열리게 되고 도어가 닫힐때는 브레이크에 의해 멈춰있던 상태에서 힘을 가하면 자동적으로 닫히게 되는 것이다.The rotary door is rotated by a shaft hinged on one side of the door and is opened by human force when the door is opened. When the door is closed, the door is automatically closed by applying a force while the door is closed.
이와같은 기능을 수행하는 장치는 통상적으로 도어에 장치되는 도어체크에 의하여 이루워지거나 도어의 하부힌지에 연결된 장치에 의하여 동작되는 것이다.Devices that perform this function are typically made by a door check mounted to the door or operated by a device connected to the lower hinge of the door.
회전식 도어가 기본적으로 갖춰야 할 기능은 적은 힘을 받더라도 쉽게 열려야하고 닫힐때는 회전속도가 점차 감소되면서 마지막에는 아주 느리게 닫혀져야 만이 안전사고를 막을수가 있게 되고 도어를 여닫을때 소음발생이 적어야만 하는 것이다.The basic function of the revolving door is to open it easily even with little force, and when it closes, the rotation speed decreases gradually and closes very slowly at the end to prevent safety accidents and to generate less noise when opening and closing the door.
종래에는 여러가지 구조의 도어 회전력 제어구조가 알려지고 있으나 도어가 열릴때는 가볍고 신속하게 열릴수 있도록 하는 구조는 거의 만족스러울 만큼 개선되고 있으나 도어가 닫힐때의 속도제어는 만족스럽지 못한 문제점이 있는 것이다.Conventionally, door rotational force control structures of various structures are known, but the structure for allowing the door to be opened lightly and quickly is improved almost satisfactorily, but the speed control when the door is closed is not satisfactory.
이와같은 문제점을 해결하기 위하여 스프링의 탄발력을 이용하거나 오일 또는 에어압력을 이용하는 기술적 구조가 알려지고 있는 것이다.In order to solve this problem, the technical structure using the spring force or the oil or air pressure is known.
그러나 스프링의 탄발력을 이용하는 것은 닫힐때의 속도조절이 매우 까다롭고 소음이 많이 발생되는 문제점과 장시간 사용할 경우 스프링의 탄발력이 저하되어 기능을 만족스럽게 수행하지 못하는 문제점이 있었던 것이다.However, using the spring force of the spring was very difficult to control the speed of closing and the noise is a lot of problems and the use of the spring has a problem that can not be satisfactorily performed due to the decline of spring force.
또한 유압이나 공기압을 이용하는 것은 동작상태가 유연하고 부드럽지만 구조가 복잡하고 소음발생을 크게 개선할 수가 없는 문제점이 있었던 것이다.In addition, the use of hydraulic pressure or air pressure has a problem in that the operation state is flexible and soft, but the structure is complicated and noise can not be greatly improved.
본 고안은 상기 종래 회전식 도어의 회전력 제어구조의 문제점을 효과적으로 해결하기 위한 것으로 구조가 매우 간단하면서 만족할 만한 회전력 제어기능을 갖는 도어의 회전력 제어구조를 제시한다.The present invention is to solve the problems of the rotational force control structure of the conventional rotary door effectively proposes a rotational force control structure of the door having a very simple and satisfactory rotational force control function.
본 고안은 스프링에 의한 도어 복귀력과 유압과 자석을 이용한 회전력 제어수단을 제시하는 것으로 특히 도어가 닫힐때 마지막 도어와 문틀의 간격이 약 50cm 정도 일때 회전속도가 크게 떨어지면서 도어가 천천히 닫히게 되고 소음발생이 전혀 없는 상태에서 도어가 닫히도록 하는 것이 본 고안의 기술적 과제이다.The present invention proposes the door return force by spring and the rotational force control means using hydraulic and magnet. Especially when the door is closed, when the distance between the last door and the door frame is about 50cm, the rotation speed drops greatly and the door closes slowly and makes noise. It is a technical problem of the present invention to close the door in a state where there is no occurrence.
본 고안은 이와같은 기술적 과제를 해결하기 위하여 유압과 자력을 응용하여 도어의 회전력을 제어한다.The present invention controls the rotational force of the door by applying hydraulic pressure and magnetic force in order to solve this technical problem.

상기한 구성으로 이루워진 본 고안의 작용효과를 설명한다.It describes the effect of the present invention made of the above configuration.
하우징(h)에 형성된 캠구동공간(10)과 실린더공간(20)에는 오일이 차 있다.Oil is filled in the cam driving space 10 and the cylinder space 20 formed in the housing h.
도1, 도2, 도3은 도어복귀스프링(s)의 탄발력에 의하여 도어가 닫혀 있는 상태를 보인것으로 도2, 도3과 같이 압축피스톤(70)의 선단에 끼워진 이동영구자석(M1)이 황동부재(c) 내로 완전히 진입된 상태이다.1, 2, and 3 show the state in which the door is closed by the repulsive force of the door return spring s. As shown in FIGS. 2 and 3, the movable permanent magnet M1 fitted to the tip of the compression piston 70 is shown. It is in the state fully entered into this brass member (c).
상기 이동영구자석(M1)과 고정영구자석(M2)은 자극이 서로 마주보도록 설치함으로써 항시 서로 미는 힘을 유지하고 있다.The movable permanent magnet M1 and the fixed permanent magnet M2 are installed to keep the magnetic force pushing each other by installing the magnetic poles facing each other.
그러나 압축피스톤(70)이 도어힌지 쪽으로 밀려나지 않는 것은 도어복귀스프링(s)의 탄발력 때문이다.However, the compression piston 70 is not pushed toward the door hinge because of the elasticity of the door return spring (s).
이와같은 상태에서 힘을 가해 도어(d)를 밀면 이동영구자석(M1)과 고정영구자석(M2)의 미는 힘에 의하여 도어(d)가 가볍게 회전하게 되고 도어힌지(h)에 고정된 캠(30)이 따라 회전되면서 캠(30)의 주벽면이 캠접촉로울러(50')에 접촉되어 밀어주면 캠접촉로울러(50)(50')에 고정된 상하이동판(40)(40')이 좌측으로 이동되면서 구동롯드(60)에 장착된 압축피스톤(70)이 도어복귀스프링(s)을 압축시키게 되고 도어가 90도 정도 회전되면 캠(30) 주벽에 형성된 도어스톱홈(31)에 캠접촉로울러(50')가 안착되면서 도어가 열린상태로 있게 된다.When the door (d) is pushed by the force in such a state, the door (d) is lightly rotated by the pushing force of the moving permanent magnet (M1) and the fixed permanent magnet (M2), and the cam (h) fixed to the door hinge (h) 30 is rotated along the main wall surface of the cam 30 is in contact with the cam contact roller (50 ') to push the shank copper plate 40, 40' fixed to the cam contact roller (50, 50 ') left Compression piston 70 mounted on the drive rod 60 compresses the door return spring s while being moved to the cam, and when the door is rotated about 90 degrees, the cam contact the door stop groove 31 formed on the main wall of the cam 30. As the roller 50 'is seated, the door is left open.
도어를 더 열어 놓으려면 도어를 다시 밀어서 약간 회전시키면 캠접촉로울러(50')가 도어스톱홈(32)에 안착되어 도어가 조금 더 열리게 되는 것이다.To open the door further, push the door again and rotate it slightly so that the cam contact roller 50 'is seated in the door stop groove 32, so that the door is slightly opened.
이와같은 상태에서 도어를 반대로 회전시키면 캠(30)의 도어스톱홈이 캠접촉로울러에서 벗어남과 동시에 도어복귀스프링(s)의 탄발력에 의하여 상하이동판(40)(40') 구동롯드(60) 압축피스톤(70)이 우측으로 이동하게 되고 압축피스톤(70)에 고정된 이동영구자석(M1)이 황동부재(c) 내로 진입될 때 황동과 영구자석의 특성에 의해 마찰자기력이 발생되면서 압축피스톤(70)의 이동속도가 저하되고 이동영구자석(M1)이 고정영구자석과 가까워 질수록 상호 반발자기력의 발생으로인하여 압축피스톤(70)의 이동속도는 점차 떨어지게 되어 도어가 마지막에는 아주 천천히 닫히게 됨으로 특히 어린아이들에게서 많이 발생하는 손이나 손가락이 부상당하거나 도어의 타격압력에 의해 발생되는 안전사고를 방지할 수가 있게 되고 도어를 여닫을 때 소음을 최소한으로 줄일수 있는 것이다.In such a state, when the door is rotated in reverse, the door stop groove of the cam 30 is released from the cam contact roller, and at the same time, the shank copper plate 40, 40 'driving rod 60 is caused by the elasticity of the door return spring s. When the compression piston 70 moves to the right and the moving permanent magnet M1 fixed to the compression piston 70 enters the brass member c, the friction magnetic force is generated by the characteristics of the brass and the permanent magnet. As the movement speed of 70 decreases and the moving permanent magnet M1 gets closer to the fixed permanent magnet, the movement speed of the compression piston 70 gradually decreases due to the occurrence of mutual repulsive magnetic force, so that the door closes very slowly at the end. In particular, it is possible to prevent safety accidents caused by injured hands or fingers or the impact pressure of the door, which occurs frequently in children, and to minimize noise when opening or closing the door. It can be.
압축피스톤(70) 내에 장치된 볼밸브(83)는 도어가 닫힐때 실린더공간(20)의 좌측에 차 있는 오일이 오일개폐밸브실(80)을 통해 우측 실린더공간(20)으로 유입되는 것을 막고 오일이 압력조절밸브(90)를 통해 우측 실린더공간(20)으로 유입되게 함으로써 도어가 천천히 닫히도록 하며,The ball valve 83 installed in the compression piston 70 prevents oil filled on the left side of the cylinder space 20 from entering the right cylinder space 20 through the oil opening / closing valve chamber 80 when the door is closed. The oil is introduced into the right cylinder space 20 through the pressure regulating valve 90 to close the door slowly,
도어가 열릴때는 볼밸브(83)가 오일유통공(81)을 열어줌으로써 도어가 가볍게 열리도록 하는 것이다.When the door is opened, the ball valve 83 opens the oil distribution hole 81 so that the door is opened lightly.
안전밸브(91)는 도어를 열거나 닫을 때 과격한 힘이 가해지면서 도어가 파손되는 등의 문제점을 없애기 위하여 설치된 것으로 과한 압력을 받게 되면 자동적으로 열리도록 되어 있다.Safety valve 91 is installed in order to eliminate problems such as the door is broken while being applied to the excessive force when opening or closing the door is automatically opened when subjected to excessive pressure.
상기한 구성 및 작용효과를 가지게 되는 본 고안은 도어가 열릴때는 도어복귀스프링의 탄발력을 감소시켜 가볍게 회전되도록 하기 위하여 같은 자극이 마주보도록 이동영구자석과 고정영구자석을 설치하고 도어가 닫힐때는 이동영구자석과 황동부재에 의한 마찰자기력에 의해 회전속도를 점차 감소시키고 이동영구자석과 고정영구자석에 의한 상호 반발자기력에 의하여 도어가 닫히는 마지막 단계에서 도어의 회전속도를 크게 감소시켜 안전사고를 방지할 수 있으며 도어가 개폐될때 소음을 감소시키는 효과를 얻게 되는 것이다.The present invention, which has the above-described configuration and working effect, installs a permanent permanent magnet and a fixed permanent magnet such that the same magnetic poles face the same magnetic poles in order to reduce the elasticity of the door return spring when the door is opened so that it rotates lightly and moves when the door is closed. In order to prevent safety accidents, the rotational speed is gradually reduced by the frictional magnetic force of the permanent magnet and the brass member, and the rotational speed of the door is greatly reduced at the last stage of the door closing due to mutual repulsion magnetism by the moving permanent magnet and the fixed permanent magnet. It is possible to reduce the noise when the door is opened and closed.
