Description

도어 개폐장치에 있어서 도어의 회전속도 제어구조{Rotation rate control structure of door opening and closing device}Rotation rate control structure of door opening and closing device

본 고안은 힌지를 중심으로 회전되면서 개폐되는 회전식 도어에 있어서 도어가 개폐될때 회전속도를 제어하는 구조에 관한 고안이다.The present invention is a device for controlling the rotational speed when the door is opened and closed in the rotary door that is opened and closed while rotating around the hinge.

회전식 도어는 도어의 일측 상하부에 축설되는 힌지를 중심으로 도어가 열릴때는 사람의 힘에 의하여 열리게 되고 도어가 닫힐때는 고정브레이크에 의해 멈춰있던 상태에서 도어에 힘을 가하면 브레이크가 풀리면서 스프링의 탄발력이나 유압실린더의 제어에 의하여 자동적으로 닫히게 되는 것이다.The rotary door is opened by human force when the door is opened, centering on the hinge installed on one side of the door, and when the door is closed by applying a brake, the brake is released when the force is applied to the door. It is automatically closed by the control of the hydraulic cylinder.

이와같은 기능을 수행하는 장치는 통상적으로 도어에 장치되어 유압으로 구동되는 도어 체크에 의해 이루워지거나 도어의 하부힌지에 장치된 유압실린더의 코일스프링에 의하여 동작되는 것이다.A device for performing such a function is typically performed by a door check driven by a hydraulic pressure mounted on a door or operated by a coil spring of a hydraulic cylinder mounted on a lower hinge of the door.

회전식 도어가 기본적으로 갖추어야 할 기능은 적은 힘을 받더라도 쉽게 열려야 하고 닫힐때는 회전속도가 점차 감소되면서 마지막에는 아주 느리게 회전되면서 닫혀져야만 도어와 문틀 사이에 손이 끼거나 출입하는 사람이 부딛혀서 발생되는 안전사고를 막을 수가 있는 것이다.The basic function of the revolving door should be easy to open even with little force, and when it is closed, the rotation speed will gradually decrease and at the end, it should be closed with very slow rotation. You can prevent accidents.

종래에도 여러가지 구조의 도어 회전속도 제어구조가 알려지고 있는 것으로 도어가 열릴때는 가볍고 신속하게 회전되면서 열릴 수 있는 구조는 거의 만족스러울 만큼 개선되고 있으나 도어가 닫힐때의 회전속도 제어는 만족스럽지 못한 문제점이 있는 것이다.Conventionally, the door rotation speed control structure of various structures is known, and when the door is opened, the structure that can be opened while being lightly and quickly rotated is almost satisfactory, but the rotation speed control when the door is closed is not satisfactory. It is.

이와같은 문제점을 해결하기 위하여 스프링의 탄발력을 이용하거나 오일 또는 에어압력을 이용하는 구조가 알려지고 있는 것이다.In order to solve this problem, the structure using the spring force or the oil or air pressure is known.

실용신안등록 제262510호(유압식 플로어 힌지의 유압조절구조)로 알려지고 있는 선행기술의 구조를 보면 도어의 회전에 의하여 좌우로 이동되는 피스톤 롯드에 설치된 피스톤이 출입되는 실린더에 유체배출통로를 형성하고 있으며 유체배출통로는 실린더 내측으로 갈수록 좁게 형성하여 도어가 닫히면서 피스톤이 실린더 내로 유입될 때 유체통로로 빠져나오는 유체의 양이 점차 감소되면서 피스톤이 실린더 내로 유입되는 속도를 감소시켜 도어가 점차 천천히 닫히도록 하는 구조가 알려지고 있는 것이다.According to the structure of the prior art known as Utility Model Registration No. 262510 (Hydraulic control structure of the hydraulic floor hinge), the fluid discharge passage is formed in the cylinder through which the piston installed in the piston rod moved to the left and right by the rotation of the door. The fluid discharge passage is formed narrower toward the inside of the cylinder. As the door is closed, the amount of fluid flowing out of the fluid passage decreases gradually as the piston enters the cylinder. The structure to make it known is known.

그러나 상기한 선행기술은 별도로 구성되는 실린더 내벽에 유체배출통로를 구성시키므로서 유체배출통로를 성형하는 제작공정이 까다롭고 유체배출통로가 마모되거나 손상됐을 때 고장수리가 어려워서 실린더 전체를 교체해야 하기 때문에 교체하는데 소요되는 비용이 과다하여 호환성이 떨어지는 문제점이 있게 되는 것이다.However, since the above-mentioned prior art configures the fluid discharge passage on the inner wall of the cylinder separately, the manufacturing process of forming the fluid discharge passage is difficult, and when the fluid discharge passage is worn or damaged, it is difficult to repair the trouble so that the entire cylinder needs to be replaced. Excessive cost of replacement will have a problem of incompatible compatibility.

또한 실린더 내의 유체가 유체통과량제어밸브를 통하여 반대쪽 실린더로 유입되지 않고 직접 반대쪽 실린더로 유입됨으로 유체의 배출 또는 유입량이 항시 일정하여 도어의 회전력을 미세하게 조절할 수가 없는 문제점이 있게 되는 것이다.In addition, since the fluid in the cylinder is not directly introduced into the opposite cylinder through the fluid flow control valve, the discharge or inflow of the fluid is always constant so that the rotational force of the door cannot be finely adjusted.

본 고안은 상기한 종래 기술의 문제점을 효과적으로 해결하기 위하여 도어가 개폐될 때 실린더 내에서 피스톤 롯드에 의해 좌우로 이동되는 피스톤의 선단부에 별도의 유체제어부재가 착설되며 유체제어부재에는 도어가 개폐될 때 도어의 회전속도를 이상적으로 제어할 수 있는 기능을 부여함으로서 본 고안이 추구하는 도어의 회전기능이 효과적으로 수행될 수 있도록 하는 것이 본 고안의 기술적 과제이다.In order to solve the above problems of the prior art, a separate fluid control member is installed at the distal end of the piston which is moved from side to side by the piston rod in the cylinder when the door is opened and closed, and the door is opened and closed at the fluid control member. It is a technical task of the present invention to provide a function capable of ideally controlling the rotational speed of the door so that the rotation function of the door pursued by the present invention can be effectively performed.

하우징(h)에 형성된 캠 구동공간(10)과 실린더공간(20)에는 유체가 차 있다.Fluid is filled in the cam drive space 10 and the cylinder space 20 formed in the housing h.

도1, 도2는 도어가 닫혀 있는 상태의 단면을 보인 것으로, 압축피스톤(80)과 실린더공간(20) 내벽 사이에 탄설되어 구동롯드(70)가 통과하고 있는 도어복귀스프링(s)의 탄발력에 의하여 압축피스톤(80)이 우측으로 이동되면서 도어(d)가 자동적으로 닫히게 되는 것이다.1 and 2 show a cross-sectional view of a closed door, which is coalesced between the compression piston 80 and the inner wall of the cylinder space 20, and burns the door return spring s through which the driving rod 70 passes. As the compression piston 80 is moved to the right by the force, the door d is automatically closed.

도어(d)가 열리고 닫히는 과정을 보다 구체적으로 설명한다.The process of opening and closing the door d will be described in more detail.

도3은 도어(d)가 열린 상태로 고정되어 있는 것을 보인 것으로 닫혀있던 도어를 열기 위하여 강제적으로 밀게 되면 도어힌지(1)가 회전되고 도어힌지(1)에 고정된 캠(40)이 회전하게 되고 캠(40)이 회전되면서 상하이동판(50)(50')의 좌측 전후방에 설치된 캠접촉로울러(60)를 좌측으로 밀게되면 캠접촉로울러(60)가 캠(40)에 의해 밀리면서 상하이동판(50)(50')이 좌측으로 이동되다가 캠(40)에 형성된 캠스톱홈(41)에 안착되면 도어가 90도 각도로 열린 상태에서 멈추게 되는 것으로 도어가 회전될 때 상하이동판(50)(50')에 고정된 구동롯드(70)가 압축피스톤(80)을 좌측으로 끌어 당겨 좌측실린더공간(20) 내의 유체가 압축피스톤(80)의 이동압력으로 인하여 압축피스톤(80) 내부의 유체통로로 유입되며 유체의 유입 압력에 의하여 유체개폐제어부재(200)의 볼밸브(240)가 열리게 되고 유체개폐제어부재(200)는 유체개폐제어부재받침스프링(210)의 탄발력에 의하여 유체제어고정부재(100)의 우측으로 일부가 노출되어 있는 상태이며 이와같은 상태에서는 유체개폐제어부재(200)의 내측의 주벽에 요설된 유체출입홈(220)의 깊고 넓은 선단부와 상기 유체제어고정부재(100)에 천공된 유체출입공(120)과 일치된 상태가 됨으로 유체개폐제어부재(200)의 유체통로(210)와 상기 유체출입공(120) 및 유체출입홈(220)을 통해서 좌측실린더공간(20) 내의 많은 양의 유체가 우측실린더공간(20)으로 유입되면서 도어의 회전속도가 빨라지고 가볍게 열리게 되는 것이다.Fig. 3 shows that the door d is fixed in an open state, and when it is forcibly pushed to open the closed door, the door hinge 1 is rotated and the cam 40 fixed to the door hinge 1 is rotated. When the cam 40 is rotated and the cam contact roller 60 installed at the front left and right of the shanghai copper plates 50 and 50 'is pushed to the left side, the cam contact roller 60 is pushed by the cam 40 and the shank copper plate is rotated. 50 and 50 'are moved to the left side and seated in the cam stop groove 41 formed in the cam 40, the door stops in the open state at an angle of 90 degrees. The driving rod 70 fixed to the 50 'pulls the compression piston 80 to the left, and the fluid in the left cylinder space 20 flows into the fluid passage inside the compression piston 80 due to the moving pressure of the compression piston 80. The ball valve 240 of the fluid opening and closing control member 200 is opened by the inlet pressure of the fluid The fluid opening and closing control member 200 is a state in which a part of the fluid opening and closing control member support spring 210 is exposed to the right side of the fluid control fixing member 100, and in this state, the fluid opening and closing control member ( The fluid opening / closing control member 200 may be in a state consistent with the deep and wide tip of the fluid access groove 220 recessed in the inner circumferential wall of the inner wall 200 and the fluid access hole 120 drilled into the fluid control fixing member 100. A large amount of fluid in the left cylinder space 20 flows into the right cylinder space 20 through the fluid passage 210, the fluid access hole 120, and the fluid access groove 220, thereby increasing the rotation speed of the door. It will open lightly.

도어를 닫히고자 할때는 도3과 같이 열려 있는 도어를 약간의 힘을 가해 당기게 되면 도어힌지의 회전에 의하여 캠(40)이 회전되면서 캠(40)에 형성된 도어스톱홈(41)에 안착되어 있는 캠접촉로울러(60)가 도어스톱홈(41)에서 벗어나면서 수축되어 있던 도어복귀스프링(s)의 탄발력에 의하여 압축피스톤(80)이 우측으로 이동하면서 구동롯드(70)와 상하이동판(50)(50')을 우측으로 끌어당기게 되면 캠접촉로울러(60)가 캠(40)을 회전시켜서 도어가 닫히게 되고 압축피스톤(80)이 우측으로 계속 이동하다가 압축피스톤(80)에 고정된 유체제어고정부재(100)의 밖으로 노출된 유체개폐제어부재(200)의 외측단부가 하우징(h)의 캡(30) 내면에 접촉하게 되고 접촉된 상태에서 도어복귀스프링(s)의 계속된 탄발력을 받게 되면 유체개폐제어부재(200)를 받쳐주고 있던 받침스프링(s')이 수축되면서 유체개폐제어부재(200)가 유체제어고정부재(100) 내로 몰입되면 유체개폐제어부재(200)의 외주벽에 요설되어 있는 유체출입홈(220)이 내측으로 이동되면서 유체출입홈(220)의 깊고 넓은 부분이 상기 유체출입공(120)에서 멀어지게 되고 유체출입홈(220)의 낮고 좁은 쪽과 가까워지면서 우측실린더공간(20)에서 유입되는 유체의 양이 점차 줄어들게 되고 상기 볼밸브(240)는 유체통로(210)를 폐쇄시키고 있는 상태여서 우측실린더공간(20)의 유체압력이 높아지면서 도어의 회전속도는 점차 떨어지면서 도어가 서서히 닫히게 됨으로 도어와 문틀 사이에 끼여 발생되는 안전사고를 예방할 수가 있게 되고 강한 힘을 가해서 도어를 닫게되거나 바람 등에 의하여 도어가 닫힐때도 서서히 닫히게 되는 것이다.When the door is to be closed as shown in Fig. 3 when the door is pulled by applying a slight force, the cam 40 is rotated by the rotation of the door hinge and the cam is seated in the door stop groove 41 formed in the cam 40. As the compression roller 80 moves to the right by the elastic force of the door return spring s that is contracted while the contact roller 60 is released from the door stop groove 41, the driving rod 70 and the shank copper plate 50 are moved. When the 50 'is pulled to the right, the cam contact roller 60 rotates the cam 40 to close the door, and the compression piston 80 continues to move to the right, and the fluid control fixing fixed to the compression piston 80 is performed. The outer end of the fluid opening / closing control member 200 exposed out of the member 100 comes into contact with the inner surface of the cap 30 of the housing h and receives a continuous repulsive force of the door return spring s in the contacted state. When the support spring that was supporting the fluid opening and closing control member 200 ( When the fluid opening and closing control member 200 is immersed into the fluid control fixing member 100 as the s' is contracted, the fluid access groove 220 recessed in the outer circumferential wall of the fluid opening and closing control member 200 is moved inwardly and the fluid is opened. As the deep and wide portions of the entrance and exit grooves 220 move away from the fluid entry hole 120 and approach the lower and narrow sides of the fluid entry grooves 220, the amount of fluid flowing in the right cylinder space 20 gradually decreases. The ball valve 240 is in a state in which the fluid passage 210 is closed, and as the fluid pressure of the right cylinder space 20 increases, the rotation speed of the door gradually decreases, so that the door is gradually closed and is caught between the door and the door frame. The safety accident can be prevented and the door is closed with a strong force or the door is closed slowly even when the door is closed by wind.

도어를 열때는 사람의 힘에 의하여 도어가 회전하게 됨으로 캠(40)에 의하여 상하이동판(50)(50')과 구동롯드(70) 및 압축피스톤(80)이 좌측으로 강제 이동하게 되면 캡(30) 내면에 접촉되어 유체제어고정부재(100)로 몰입되어 있던 유체개폐제어부재(200)가 받침스프링(s')의 탄발력에 의하여 원상으로 복귀되면서 유체출입공(120)과 일치된 상태에 있던 유체출입홈(220)의 낮고 좁은 쪽에서 점차 깊고 넓은 쪽과 연통되게 이동되면서 점차 많은 양의 유체가 통과하게 되고 볼밸브(240)도 열려 있는 상태여서 많은 양의 유체가 유입됨으로 도어의 회전속도가 빨라지고 가볍게 열리게 되는 것이다.(도3 참조)When the door is rotated by the force of a person when opening the door, the shank copper plate 50, 50 ', the driving rod 70 and the compression piston 80 are forced to the left by the cam 40. 30) the fluid opening / closing control member 200, which is in contact with the inner surface and immersed in the fluid control fixing member 100, returns to its original state by the elastic force of the support spring s', and is consistent with the fluid access hole 120. In the lower and narrow side of the fluid access groove 220 was gradually moved in communication with the deep and wide side, and a large amount of fluid is passed through and the ball valve 240 is also open so that a large amount of fluid is introduced to rotate the door It will be faster and lighter (see Figure 3).

그리고 상기 유체제어고정부재(100)의 내벽에 요설되어 있는 원형요구(130)는 유체출입공(120)과 연통되게 구성되어 있어서 유체개폐제어부재(200)의 외주벽 한곳에만 요설되어 있는 유체출입홈(220)이 유체개폐제어부재(200)가 회전되더라도 상기 원형요구(130)와 항시 연통된 상태에서 유체출입공(120)으로 유체가 통과할 수 있도록 하기 위한 것이다.In addition, the circular request 130, which is formed on the inner wall of the fluid control fixing member 100, is configured to communicate with the fluid access hole 120, and thus the fluid access, which is required only on one outer circumferential wall of the fluid opening and closing control member 200, is performed. The groove 220 is intended to allow fluid to pass through the fluid access hole 120 in a state of always communicating with the circular demand 130 even when the fluid opening and closing control member 200 is rotated.
