본 고안은 문을 천천히 닫히게 되는 도어 체크(door check)에 관한 것으로, 보다 상세하게는 문을 열고 닫히게 하는 유압체크케이싱을 문의 상단부내부에 장착하고, 유압체크케이싱내의 체크피스톤은 피봇힌지(pivothinge)의 피봇(pivot)에 감기거나 풀려지는 와이어케이블에 의하여 작동토록 한 것으로, 이와같은 본 고안은 유압체크케이싱이 문의 상단부에 내장시키므로서 문의 외장에는 어떠한 돌출물이나 그 돌출물에 의한 손상 등을 없게하는 장점과, 유압체크케이싱 상단으로 돌설되는 작동로울러와 피봇힌지의 피봇을 와이어케이블로 연결시키는 조립작업만으로 설치 할 수 있어 도어 체크의 설치작업을 간편, 신속하게 수행할 수 있게 하는데 목적을 두고 있으며, 또한 문상단부로 돌설된 작동로울러의 하단부에 형성되어 있는 래치트휠(ratchet wheel)에 발톱을 접속시켜주는 작동수단으로 문을 열어놓은 상태 그대로 유지시킬 수도 있게 하는 기능을 부가한 것이다.The present invention relates to a door check that closes the door slowly. More specifically, a hydraulic check casing for opening and closing the door is mounted inside the upper end of the door, and the check piston in the hydraulic check casing is pivot hinged. It is operated by a wire cable wound or unwound by a pivot, and the present invention has the advantage that the hydraulic check casing is built into the upper end of the door so that no protrusion or damage caused by the protrusion is provided on the exterior of the door. And, it can be installed only by the assembly work that connects the operation roller and the pivot hinge pivot to the top of the hydraulic check casing with a wire cable, so that the installation work of the door check can be easily and quickly performed. On the ratchet wheel formed at the lower end of the operation roller protruding to the upper end of the door One will add a function to allow also be maintained as with open door to the operating means of connection to the top.
종래의 도어 체크는 그의 유압체크케이싱을 문의 외측 상단에 돌출되게 부착하고, 또한 유압체크케이싱 상단으로 돌설된 회전봉을 회전시키는 링크에 연결된 또하나의 링크를 문틀에 부착시켜야 하므로서 도어 체크의 부착 작업이 번거로운 단점이 있었으며, 나아가 유압체크케이싱과 링크의 부착위치를 정확하게 맞추지 않게 되면 도어체크의 작동이 않되기 때문에 도어 체크의 부착작업이 매우 까다로운 문제점을 안고 있었다.The conventional door check attaches its hydraulic check casing to the outer top of the door and also attaches another link connected to the link for rotating the rotary rod protruding to the top of the hydraulic check casing to the door frame. There was a cumbersome disadvantage, and furthermore, the door check does not work properly when the attachment position of the hydraulic check casing and the link is not exactly corrected.
그리고 위와같은 도어 체크는 문 외측에 돌출되게 설치되기 때문에 문의 외장에 손상을 주는 문제점도 있었다.And the door check as described above is protruded to the outside of the door was also a problem that damage the exterior of the door.
본 고안은 상기와 같은 종래 고안의 제반 문제점을 해결하고자 안출한 것으로서, 상단문틀과 문의상단 사이에는 대략 10㎜ 내외의 틈이 형성되어 있으므로 그 틈사이에 작동로울러가 위치하도록 유압체크케이싱을 문 내상단부에 장착하고 나아가 작동로울러에 정착되는 와이어케이블을 피봇힌지의 피봇에 연결시키는 구성으로 도어체크자체가 문의 외장측에 돌출되지 않게 설치할 수 있도록 한 것으로, 이하 본 고안을 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention was devised to solve all the problems of the conventional design as described above. Since a gap of about 10 mm is formed between the upper door frame and the upper end of the door, the hydraulic check casing is positioned so that the operation roller is located between the gaps. It is attached to the upper end and further connects the wire cable settled in the operation roller to the pivot of the pivot hinge so that the door check itself can be installed so as not to protrude to the exterior side of the door. The explanation is as follows.
문틀(1)에 상, 하부 피봇힌지(2)(3)로서 문(4)을 설치하는 것에 있어서, 유압이 충진되고 중간벽(5) 일측과 체크피스톤(6) 사이에 압축스프링(7)이 탄력설치되며, 중간벽(5) 타측의 래크기어(8)를 연결간(9)으로서 체크피스톤(6)에 연결하여 원통기어(10)가 래크기어(8)를 진퇴작동시킴에 따라 체크피스톤이 압축스프링을 압축시킬 때에는 압축스프링측에 충진된 유압을 체크피스톤 이면측으로 보내는 작용과, 반대적으로 압축스프링의 복귀 탄성력에 의해 체크피스톤이 밀려갈 때에는 그 이면측이 있던 유압을 압측스프링측으로 보내는 작용으로 문(4)이 부드럽게 개폐되도록 하는 공지의 유압체크케이싱(11)을 문(4)의 상단내부에 장착한 다음, 원통기어(10)의 각형축(10a)에 발톱(12a)에 의해 제어되는 래치트휠(12)과 작동로울러(13)를 형성하며, 작동로울러에 일단이 정착된 상태로 권취된 와이어케이블(14)의 타단을 상부피봇힌지(2)의 피봇(2a)에 관통된 끼움공(2b)에 끼워 고정시켜 피봇힌지를 기점으로 하여 문이 개폐됨에 따라 와이어케이블의 양단이 피봇(2a)과 작동로울러(13)에 상호 반대적으로 감기고 풀어지면서 원통기어가 래크기어를 진퇴작동시킬 수 있도록 구성하여서 된 것이다.In installing the door 4 as the upper and lower pivot hinges 2 and 3 in the door frame 1, the hydraulic pressure is filled and the compression spring 7 between one side of the intermediate wall 5 and the check piston 6 is provided. The elastic gear is installed, and the rack gear 8 on the other side of the intermediate wall 5 is connected to the check piston 6 as the connecting member 9 so that the cylindrical gear 10 moves the rack gear 8 forward and backward. Therefore, when the check piston compresses the compression spring, the hydraulic pressure filled to the compression spring side is sent to the back side of the check piston. On the contrary, when the check piston is pushed by the return elastic force of the compression spring, the hydraulic pressure of the back side is pressed. A well-known hydraulic check casing 11 is mounted inside the upper end of the door 4 to allow the door 4 to be opened and closed smoothly by sending it to the spring side, and then the claw 12a on the square shaft 10a of the cylindrical gear 10. And an actuating roller 13 and a ratchet wheel 12 controlled by the The other end of the wire cable 14 wound in a fixed state is fixed to the fitting hole 2b penetrated by the pivot 2a of the upper pivot hinge 2 so that the wire is opened and closed as a starting point of the pivot hinge. The both ends of the pivot (2a) and the operating roller (13) is wound and unwinding mutually opposite to the cylindrical gear is configured to allow the rack gear to move forward and backward.
이와같이 구성된 본 고안의 설치작업 및 작용효과를 설명하면 다음과 같다.Referring to the installation operation and the effect of the present invention configured as described above are as follows.
문(4)의 상단내부에 장착되는 유압체크케이싱(11)의 상단으로 돌설된 원통기어(10)의 각형축(10a)에 축착시킨 작동로울러(13)는 문의 상단과 상부측 문틀 사이에 형성된 틈에 위치하도록 설치하는 것이며, 또한 작동로울러(13)에 대략 3/4 정도 권취된 상태하에서 그 단부가 용접등으로 정착하고, 와이어케이블(14)의 타단은 상부피봇힌지(2)의 피봇(2a)을 안쪽으로 돌아 끼움공(2b)에 끼워 고정시켜주면 도어체크의 설치작업이 완료되는 것이다.An operation roller 13 fixed to the square shaft 10a of the cylindrical gear 10 protruding to the upper end of the hydraulic check casing 11 mounted inside the upper end of the door 4 is formed between the upper end of the door and the upper side door frame. It is installed so as to be located in the gap, and the end of the wire cable 14 is fixed by welding or the like while being wound about 3/4 of the operation roller 13, and the other end of the wire cable 14 is pivoted by the upper pivot hinge 2 ( If 2a) is screwed into the fitting hole (2b) and fixed, the installation work of the door check is completed.
상기에서 상부피봇힌지(2)의 상판과 하판에 끼워지는 피봇(2a)은 하판에 끼워지는 하부는 원통상으로 구성되고, 또 원통상 하부의 높이는 상판과 하판에 와이어케이블(14)을 삽입시킬 수 있는 공간이 마련되게 하는 높이를 가지면서 상판을 지지하고 있도록 한 것이며, 상판에 끼워지는 상부는 사각형으로 구성하여 피봇(2a)자체가 회전되지 않도록 하므로서 문을 개폐할 경우 피봇(2a)은 정지된 상태하에서 상부피봇힌지(2)의 하판이 피봇의 원통상 하부외주를 타고 미끄러지듯 회전하도록 문이 원활하게 개폐작동되도록 한 것이다.In the above pivot (2a) that is fitted to the upper plate and the lower plate of the upper pivot hinge (2) has a lower portion fitted to the lower plate is composed of a cylindrical shape, and the height of the cylindrical lower portion to insert the wire cable 14 to the upper plate and the lower plate. It has a height that allows a space to be provided to support the top plate, and the upper part fitted to the top plate is formed in a quadrangle so that the pivot (2a) itself is not rotated so that the pivot (2a) stops when opening and closing the door. Under the condition that the lower plate of the upper pivot hinge (2) is to move smoothly opening and closing operation so as to slide around the cylindrical lower outer periphery of the pivot.
상기와 같이 설치된 도어체크의 작동상태를 설명하면, 문(4)을 닫은 상태에서는 작동로울러(13)에 와이어케이블(14)의 일단이 약 3/4 정도 감긴상태로 권취되어 있고, 그 타단은 상부피봇힌지의 피봇(2a)안쪽으로 돌아서 끼움공(2b)에 끼워진 상태로서 와이어케이블(14)자체는 긴장된 상태를 유지하고 있게 된다.When the operation state of the door check installed as described above is explained, one end of the wire cable 14 is wound around the operation roller 13 in a state in which the door 4 is closed and wound about 3/4, and the other end is The wire cable 14 itself is kept in a tensioned state as it is inserted into the fitting hole 2b by turning inside the pivot 2a of the upper pivot hinge.
상기와 같은 상태에서 문을 열게 되면 피봇(2a)에 고정된 와이어케이블(14)의 타단이 피봇(2a)외주에 감기기 시작하며, 이와는 반대로 와이어케이블(14)의 일단이 권취되어 있는 작동로울러(13)는 피봇(2a)에 감기는 길이만큼씩 풀어주는 작동을 개시하게 되므로서 작동로울러는 도면상 반시계방향으로 회전하기 시작하며(제2도 및 제5도 참조), 이에 따라 유압체크케이싱(11)에 장착되어 있는 원통기어(10)가 제자리에서 반시계방향으로 회전하면서 래크기어(8)를 일측으로 이동시키게 되어 연결간(9)으로 연결되어 있는 체크피스톤(6)은 압축스프링(7)을 압축하면서 래크기어와 같은 방향으로 이동하게 되는데, 이때 유압체크케이싱(11)내에는 유압이 충진되어 있는 상태이기 때문에 체크피스톤(6)는 그에 형성된 유압통로로 유압이 이동하는 량만큼씩 이동하게 됨과 동시 이와같은 체크피스톤의 이동상태는 와이어케이블(14)에도 미치게 되므로서 문(4)은 부드럽게 열리게 되는 것이며, 또한 문을 닫는 작동에 있어서는, 문 개방시 압축되어 있던 압축스프링(7)의탄성복귀력에 의하여 체크피스톤(6)이 문 개방시와는 반대방향으로 이동하기 시작하면서 래크기어(8)를 잡아당겨 주는데, 이때 체크피스톤의 이면측에 충진된 유압은 체크피스톤의 이동력에 의해 유압체크케이싱(11)내벽에 형성된 회수통로를 통해 체크피스톤 전방측(압축스프링)으로 일정유속으로 회수되므로서 체크피스톤(6)은 천천히 밀려나면서 래크기어(8)를 잡아당기게 되어 원통기어(10)가 회전하게 되므로서 각형축(10a)에 설치된 작동로울러(13)는 시계방향으로 회전하면서 와이어케이블(14)을 감는 작동에 따라 피봇(2a)에 감겨있던 와이어케이블은 끼움공(2b)에 끼워 고정된 타단은 그대로 정지되어 있는 상태하에서 피봇의 외주에 감겨있는 부분이 서서히 풀어지도록 하므로서 문이 부드럽게 닫히도록 하는 것이다.When the door is opened in the above state, the other end of the wire cable 14 fixed to the pivot 2a starts to be wound around the outer periphery of the pivot 2a. On the contrary, an operation roller in which one end of the wire cable 14 is wound ( 13) starts to release by the length of winding to the pivot (2a), the operation roller starts to rotate counterclockwise in the drawing (see Figs. 2 and 5), accordingly hydraulic check casing Cylindrical gear (10) mounted on (11) rotates counterclockwise in place and moves the rack gear (8) to one side, so the check piston (6) connected by the connecting member (9) is a compression spring (7) while compressing to move in the same direction as the rack gear, the hydraulic check casing 11 is filled with the hydraulic pressure, so the check piston (6) as much as the amount of hydraulic pressure moves in the hydraulic passage formed therein Move by At the same time, the movement state of the check piston is extended to the wire cable 14, so that the door 4 is opened smoothly. Also, in the operation of closing the door, the elasticity of the compression spring 7 compressed at the time of opening the door is maintained. By the return force, the check piston 6 starts to move in the opposite direction than when the door is opened, and the pull gear 8 is pulled out. At this time, the hydraulic pressure filled on the back side of the check piston is applied to the movement force of the check piston. By the recovery passage formed in the inner wall of the hydraulic check casing (11) to the check piston front side (compression spring) at a constant flow rate, the check piston (6) is pushed slowly while pulling the rack gear (8) to the cylindrical gear As the rotation (10) rotates, the operation roller (13) installed on the square shaft (10a) rotates clockwise while the wire cable wound on the pivot (2a) in accordance with the operation of winding the wire cable (14) The other end fixed to the fitting hole 2b is to allow the door to be smoothly closed while the part wound around the outer circumference of the pivot is gradually released under the stationary state.
상기에서와 같이 문을 열고 닫는 작동에 따라서 와이어케이블이 피봇에 감기는 작동 또는 작동로울러가 감는 작동에 의하여 문이 부드럽게 열리고 닫히도록 하다가 문을 열어놓고 상태를 유지시키고자 할 경우에는 문(4)내측상단에 스프링등으로 텐숀조정시킨 발톱(12a)을 래치트(12)의 이빨에 걸리게 조정하게 되면 원통기어(10)는 시계방향으로 회전하려는 회전력이 제어된 상태로서 래크기어(8)가 압축스프링측으로 이동할 수 없는 상태이므로 압축스프링(7)의 탄성복원력을 받고 있는 체크피스톤(6)은 이동이 저지된 상태로 머무르고 있게 되어 와이어케이블(14)에는 아무런 작용이 전달되지 않게되어 문은 열어놓은 상태를 유지하고 있게 되는 것이다.As described above, if the door is opened and closed smoothly by the operation in which the wire cable is wound on the pivot or the operation of the operation roller, the door is opened and maintained as described above. When the toenail 12a, which is tension-adjusted with a spring or the like, is caught on the teeth of the ratchet 12, the cylindrical gear 10 is in a state in which the rotational force to rotate clockwise is controlled and the rack gear 8 is controlled. The check piston 6, which is under the elastic restoring force of the compression spring 7, because it cannot move to the compression spring side, stays in a blocked state, so that no action is transmitted to the wire cable 14, and the door is opened. It will remain in the released state.
위와같이 열려 있는 문을 닫고자 할 경우에는 문을 여는 방향으로 조금 밀어주게 되면 래치트(8)의 이빨에 물려있는 발톱(12a)이 그 이빨에서 빠져 나옴과 동시 스프링에 의해 래치트에서 완전히 이탈된 상태가 되므로서 압축스프링(7)의 탄성복원력에 의해 체크피스톤(6)이 이동 가능한 상태가 되므로서 전술의 문닫힘작동에서 설명한 바와같이 작동로울러(13)는 시계방향으로 회전하면서 와이어케이블(14)을 잡아당겨 문이 상, 하부피봇힌지를 기점으로 하여 천천히 회전하여 부드럽게 닫히게 되는 것이다.If you want to close the open door as above, if you push it a little in the direction of opening the door, the toenail 12a, which is bitten by the teeth of the ratchet 8, comes out of the teeth and is completely released from the ratchet by the simultaneous spring. Since the check piston 6 is movable by the elastic restoring force of the compression spring 7, the operation roller 13 rotates clockwise as described in the door closing operation. 14) Pull out the door and rotate slowly around the upper and lower pivot hinges to close it gently.
이상의 본 고안은 유압체크케이싱을 문의 상단내부에 장착시키고 또 문상단부로 돌설된 작동로울러와 상부피봇힌지의 피봇에 와이어케이블을 연결시켜주므로서 유압체크케이싱은 물론이고 와이어케이블이 문의 상단부 내, 외측에 돌출되지 않게 설치할 수 있으므로 문의 내, 외장을 미려하게 장식할 수 있으며, 또한 유압체크케이싱의 유압작동을 문에 전달시키는 와이어케이블을 별도의 부착부재를 이용하지 않고 상부피봇힌지를 이용하므로서 조립, 설치가 용이한 이점이 있으며, 또한 문 상단에 설치한 발톱을 래치트에 걸어주는 작동으로 유압체크케이싱의 닫힘작동을 제어할 수 있으므로서 문을 일정각도로 열여놓을 수 있는 등의 이점이 매우 실용적인 고안인 것이다.The above invention is to install the hydraulic check casing inside the upper end of the door and to connect the wire cable to the pivot of the operation roller and the upper pivot hinge protruding to the upper end of the door. It can be installed without protruding into the door, so that the interior and exterior of the door can be decorated beautifully. Also, the wire cable that transmits the hydraulic operation of the hydraulic check casing to the door can be assembled by using the upper pivot hinge without using a separate attachment member. It is easy to install, and it is possible to control the closing operation of the hydraulic check casing by hanging the claws installed at the top of the door to the ratchet, and the advantage of opening the door at a certain angle is very practical. It is an idea.
