Abstract
Description
본 발명은 방화문의 바닥면에 설치되어 방화문의 여닫음을 단속하는 방화문용 힌지에 관한 것으로, 보다 구체적으로는 사용자에 의해 열린 방화문을 유압장치와 기계적인 결합을 이용해 도어의 닫히는 속도를 적절히 조절할 수 있도록 하는 방화문용 유압식 힌지에 관한 것이다.The present invention relates to a hinge for a fire door that is installed on the bottom of the fire door to control the opening and closing of the fire door, and more specifically, it is possible to appropriately control the closing speed of the door using a mechanical combination of the fire door opened by the user. To a hydraulic hinge for a fire door.
일반적으로 각종 출입문이나 방화문을 고정하는 방법은 문틀에 힌지나 경첩을 고정하고, 이에 도어의 일측면을 결합하여 회동자재 하면서 도어를 여닫을 수 있도록 하고 있다.In general, a method of fixing various doors or fire doors is to fix the hinge or hinge to the door frame, and to combine the one side of the door to open and close the door while rotating.
상기한 목적의 힌지는 일반적으로 유압식과 기계식이 있는바, 먼저 유압식 힌지는 도1, 도2a 및 도2b의 도시와 같이, 밀폐시킨 내부공간에 각 구성부품들과 유체를 수용하는 하우징(1)과, 상기 하우징의(1)의 일측 공간부상에서 그 하부가 회전지지되고 상부가 상기 하우징(1)의 외부로 일정부분 노출되어 문짝(D)의 하단부와 연결되는 힌지축(2)과, 상기 힌지축(2)의 중단에 일체로 형성되어 힌지축(2)과 함께 회전하는제어캠(3)과, 상기 하우징(1)의 타측 공간부상에 배설되는 실린더몸체(4)와, 상기 실린더몸체(4)에 삽입 설치되는 피스톤헤드(5)와, 상기 제어캠(3)에 그 일단부가 접촉되어 제어캠(3)의 회전에 따라 좌우로 이동하며 그 타측에는 상기 피스톤헤드(5)가 연결되는 피스톤로드(6)와, 상기 피스톤로드(6)의 외측에 끼워지고 상기 하우징(1)의 중간부에서 그 일단부가지지되어 상기 피스톤헤드의(5)의 좌우이동시 탄발력을 가하는 스프링(7)과, 상기 하우징(1)의 내부에 꽉 찬 상태로 담겨진 유체로 구성된다.The hinge of the above-mentioned purpose is generally a hydraulic and mechanical bar first, the hydraulic hinge as shown in Figures 1, 2a and 2b, the housing (1) for receiving the components and the fluid in the sealed interior space (1) And a hinge shaft (2) connected to the lower end of the door (D) by supporting a lower portion of the housing (1) on its lower portion and rotating the upper portion of the housing (1). A control cam 3 integrally formed at the interruption of the hinge shaft 2 and rotating together with the hinge shaft 2, a cylinder body 4 disposed on the other space portion of the housing 1, and the cylinder body. One end of the piston head (5) is inserted into and installed in the (4), the control cam (3) is in contact with each other and moves left and right in accordance with the rotation of the control cam (3) and the piston head (5) is connected to the other side The piston rod 6 being fitted to the outside of the piston rod 6 and in the middle of the housing 1 One is added to the support consists of a fluid contained in full, in the interior of the spring 7 exerts a resilient force of the left and right movement (5) of the piston head, wherein the housing (1).
이렇게 구성되는 유압식 플로어힌지는 문짝을 회전시켜 개방하면 도2a의 도시와 같이, 힌지축(2)이 회전하고, 그 힌지축(2)과 함께 회전하는 제어캠(3)이 피스톤로드(6)를 좌측방으로 당겨서 피스톤헤드(5)가 좌측으로 이동하는 동시에 스프링(7)이 압축된다.When the hydraulic floor hinge configured as described above is opened by rotating the door, as shown in FIG. 2A, the hinge shaft 2 rotates, and the control cam 3 that rotates together with the hinge shaft 2 includes the piston rod 6. The piston head 5 moves to the left, and the spring 7 is compressed.
이때, 스프링(7)은 문짝의 회전동작을 탄력적으로 완화시켜 주어 문짝이 급속히 열리는 것을 방지하는 작용을 한다.At this time, the spring (7) to elastically relieve the rotational motion of the door to prevent the door from opening rapidly.
반대로, 열려진 문짝이 닫혀지는 작용은 도2b의 도시와 같이, 문짝이 개방된 상태에서 문짝에 가해진 외력을 해제하면 압축된 스프링(7)의 탄발력으로 피스톤헤드(5)를 실린더몸체(4)의 내측으로 밀어 넣으면서 피스톤로드(6)를 타측방으로 이동시키고, 이동하는 피스톤로드(6)가 제어캠(3)과 힌지축(2)을 회전시킴으로써 문짝이 회전하면서 자동적으로 닫혀진다.On the contrary, the action of closing the opened door is to release the external force applied to the door while the door is opened, as shown in FIG. 2B, by the elastic force of the compressed spring 7 to move the piston head 5 to the cylinder body 4. The piston rod 6 is moved to the other side while being pushed into the inner side, and the moving piston rod 6 is automatically closed while the door rotates by rotating the control cam 3 and the hinge shaft 2.
이때, 실린더몸체(4)의 내부에 채워져 있는 유체가 조금씩 빠져 나감으로써, 급속히 복귀하려는 스프링(7)의 탄발력에 저항하여 주어 피스톤헤드(5)의 후진속도를 제어하며, 결과적으로 문짝이 서서히 회전하면서 닫혀지도록 제어하는 작용을 한다.At this time, the fluid filled in the cylinder body 4 gradually escapes, thereby resisting the spring force of the spring 7 to return rapidly, thereby controlling the backward speed of the piston head 5, and as a result, the door gradually It controls to close while rotating.
그런데 상기와 같이 설명한 종래의 유압식 힌지는 도어에 대한 원상복원력과 도어의 닫히는 속도를 조절하기 위한 설비로 인해 그 부피가 크고 또한 장기 사용시 도어의 유압 복원력이 감쇠되는 등의 문제점을 가지고 있는 실정이다.However, the conventional hydraulic hinge described above has a problem that the volume is large and the hydraulic restoring force of the door is attenuated in the long term due to the facility for adjusting the original restoring force for the door and the closing speed of the door.
본 발명은 상기와 같은 문제점을 극복하기 위해 안출된 것으로서, 기존의 유압식 힌지에 비해 그 하우징의 부피가 적으며 문의 하단부에 매설되는 공사와 그 제작비용에 있어 보다 효율적인 힌지 구조를 제시하는데 있다.The present invention has been made to overcome the above problems, it is to provide a more efficient hinge structure in the construction and its manufacturing cost is less volume of the housing than the existing hydraulic hinge and buried in the lower end of the door.

이하 첨부된 도면을 참조하여 본 발명에 따른 방화문용 유압식힌지에 대해 자세히 설명하기로 한다.Hereinafter, a hydraulic hinge for a fire door according to the present invention will be described in detail with reference to the accompanying drawings.
도 3과 도 4는 각각 본 발명에 따른 유압식힌지에 대한 구조평면도와 상기 구조평면도의 S-S'단면을 보여주는 단면구조도로서, 본 발명에 따른 유압식 힌지의 구조와 작동에 대한 설명을 위한 도면이다.3 and 4 are cross-sectional structural views showing a structural plan view of the hydraulic hinge according to the present invention and the S-S 'section of the structural plan view, respectively, and for explaining the structure and operation of the hydraulic hinge according to the present invention. .
특히 도 3은 도어가 닫힌 상태에서의 본 발명에 따른 유압식 힌지의 내부 배치를 보여주고 있다.In particular, FIG. 3 shows the internal arrangement of the hydraulic hinge according to the invention with the door closed.
본 발명에 따른 유압식 힌지는 도어(미도시)의 하단과 결합되는 힌지(10)가 도어의 열림방향 즉, (A)방향으로 회전하면 상기 힌지(10)와 치합된 랙기어(22)에 의해 상기 스프링압축피스톤(20)이 도면의 좌측방향으로 이동하게 되고, 이에 따라 유체는 상기 제2유체이동로(24)를 통해 유체유입조절강구(40)가 위치한 공간으로 이동하게 되어 상기 유체유입조절강구(40)는 상기 제2유체이동로(24)에서 멀어지고 상기 제2유체이동로(21a)는 개구되어 도어는 유체의 이동에 대한 저항이 없이 자연스럽게 열리게 된다.The hydraulic hinge according to the present invention is rotated by the rack gear 22 engaged with the hinge 10 when the hinge 10 coupled to the lower end of the door (not shown) rotates in the opening direction of the door, that is, (A). The spring compression piston 20 is moved in the left direction of the drawing, so that the fluid is moved to the space in which the fluid inlet control steel ball 40 is located through the second fluid movement path 24 is the fluid inlet control Steel ball 40 is away from the second fluid movement path 24 and the second fluid movement path 21a is opened so that the door opens naturally without resistance to the movement of the fluid.
이때 물론 상기 스프링압축피스톤(20)에 의해 압축스프링(30)은 압축되어 진다.At this time, of course, the compression spring (30) is compressed by the spring compression piston (20).
도 5는 본 발명에 따른 유압식 힌지를 이용한 도어의 개폐에 있어서 도어가 열렸을 때의 내부 배치를 도시한 도면이다.5 is a view showing the internal arrangement when the door is opened in opening and closing the door using the hydraulic hinge according to the present invention.
도어가 어느 정도의 각도이상으로 열릴 경우에는 도어를 열린상태로 고정시켜줄 필요가 있는데, 도 5의 부분확대 도면에서 보면, 상기 요홈(21)에 상기 걸림강구(80)가 걸림스프링(90)의 복원력에 의해 결합되고 이는 상기 압축스프링(30)의 복원력에 의한 스프링압축피스톤(20)의 이동에 제동을 걸어 도어가 닫히는 동작을 제지하게 된다. 물론 상기 요홈(21)과 걸림강구(80)가 결합되는 도어의 열림 고정각도는 상기 요홈(21) 또는 걸림강구(80)의 위치조절에 의해 조절가능하다.When the door is opened at a certain angle or more, it is necessary to fix the door in an open state. As shown in the partially enlarged view of FIG. 5, the locking steel 80 is caught in the recess 21 by the locking spring 90. It is coupled by a restoring force, which brakes the movement of the spring compression piston 20 due to the restoring force of the compression spring 30 to restrain the door from closing. Of course, the fixed opening angle of the door to which the groove 21 and the locking steel 80 are coupled is adjustable by adjusting the position of the groove 21 or the locking steel 80.
이후 상기 도어를 닫기 위해서는 상기 요홈(21)과 결합된 걸림강구(80)가 요홈(21)을 벗어날 수 있을 정도의 힘을 도어에 가해주어야 하는 바, 이는 사용자가 도어에 힘을 가해주게 된다.Thereafter, in order to close the door, the locking groove 80 coupled with the recess 21 should apply a force to the door so that the user can apply the force to the door.
상기 본 발명에 따른 유압식힌지에 의한 도어의 닫힘원리는 다음과 같다.The closing principle of the door by the hydraulic hinge according to the present invention is as follows.
상기 압축스프링(30)의 복원력에 의해 상기 스프링압축피스톤(20)은 도면의 오른쪽 방향으로 이동되고, 상기 힌지(10)는 피니언기어(11)가 상기 랙기어(2)와 치합되어 있으므로 닫힘 방향인 (B)방향으로 회전하게 된다.The spring compression piston 20 is moved in the right direction of the drawing by the restoring force of the compression spring 30, and the hinge 10 is closed because the pinion gear 11 is engaged with the rack gear 2. It rotates in the direction of phosphorus (B).
이때 유체는 상기 스프링압축피스톤(20) 내부로 이동되고 상기 유체의 흐름에 따르던 유체유이조절강구(40)는 상기 제2유체이동로(24)를 막아 상기 제2유체이동로(24)로는 유체가 상기 스프링압축피스톤(20) 내부로 더 이상 유입되지 않는다.따라서 유체는 상기 제3유체이동로(53)로 유입되고 상기 유압조절실린더(54)를 거쳐 힌지실린더(51)로 유입된다.At this time, the fluid is moved into the spring compression piston 20 and the fluid flow adjusting steel ball 40 which follows the flow of the fluid blocks the second fluid movement path 24 to the second fluid movement path 24. Is no longer introduced into the spring compression piston 20. Therefore, the fluid flows into the third fluid movement path 53 and flows into the hinge cylinder 51 through the hydraulic control cylinder 54.
이때 상기 유압조절실린더(54)에 구비된 유압조절나사(70)를 조절함으로써 유체의 유입양을 조절할 수 있으며, 이는 도어의 닫힘 속도를 조절할 수 있도록 하는 기능을 제공한다.At this time, by adjusting the hydraulic adjustment screw 70 provided in the hydraulic control cylinder 54, it is possible to adjust the amount of fluid inflow, which provides a function to control the closing speed of the door.
상기 힌지실린더(51)로 유입된 유체는 상기 스프링압축피스톤(20)의 외주면에 구성된 제1유체이동로(23)를 통해 상기 스프링압축피스톤(20)내부로 유입된다.The fluid introduced into the hinge cylinder 51 is introduced into the spring compression piston 20 through the first fluid movement path 23 formed on the outer circumferential surface of the spring compression piston 20.
물론 상기 도어의 닫힘에 있어서, 도어의 열린 정도가 얼마되지 않을 경우에는 상기 요홈(21)과 걸림강구(80)의 결합이 일어나지 않기 때문에 도어는 별도의 외력을 가해주지 않아도 상기 압축스프링(30)의 복원력에 의해 닫히게 된다.Of course, in the closing of the door, when the opening degree of the door is not so small, the coupling of the groove 21 and the locking steel 80 does not occur, so the door does not apply a separate external force, the compression spring (30) It is closed by the restoring force of.
상기 힌지실린더덮게(60)와 유압조절나사(70)는 상기 힌지케이스(50)에 나사식 결합이 되어 있으며, 결합부위에 고무 또는 합성수지 패킹을 더욱 부가하여 유체의 누수를 방지하고 힌지케이스(50)내부의 압력을 일정하게 유지시킬 수도 있다.The hinge cylinder cover (60) and the hydraulic adjustment screw (70) is screwed to the hinge case (50), and further rubber or synthetic resin packing to the coupling portion to prevent the leakage of fluid and the hinge case (50) The internal pressure can also be kept constant.
상기와 같이 설명한 본 발명에 따른 유압식 힌지는 현재 사용되는 유압식 힌지에 비해 내부구조가 간단하고 또한 상기 간단한 내부구조로 인해 부피가 기존의 절반정도로 줄어드는 효과가 있다.The hydraulic hinge according to the present invention described above has an effect that the internal structure is simple compared to the hydraulic hinge currently used, and the volume is reduced to about half of the existing volume due to the simple internal structure.
또한 부피의 감소로 인해 제작비의 절감효과를 기대할 수 있으며 적은 부피의 제품으로 인해 설치와 보수, 교체 등의 작업이 편리해지는 장점도 있다.In addition, due to the reduction of the volume can be expected to reduce the production cost, and the small volume of the product has the advantage of convenient installation, repair, replacement, etc. work.
