본 고안은 주로 철도차량에 설치되게 되는 슬라이딩 도어(SLIDING DOOR)의 자동닫힘 장치에 관한 것으로, 특히 밸런스 웨이트((BALANCE WEIGHT)를 이용한 단순구조의 기구학적 닫힘장치를 구축하여 제작단가를 대폭절하고, 유지보수가 용이하도록 한 슬라이딩 도어의 자동닫힘 장치에 관한 것이다.The present invention mainly relates to an automatic closing device of a sliding door to be installed in a railway vehicle, and in particular, by constructing a mechanical closing device with a simple structure using a balance weight, the manufacturing cost is greatly reduced. The present invention relates to an automatic closing device of a sliding door to facilitate maintenance.
종래에 있어서, 각종 철도차량에 장착되어 사용되고 있던 슬라이딩 도어(1)의 자동닫힘 장치는 제 1 도에 도시된 바와같이, 적정길이의 작동암(ARM)(2)일측이 차체(3)측의 고정구(3')에 회동가능한 상태로 연결설치되고, 작동암(2)의 타측단에 장착되는 로울러(4)가 도어(1) 측에 고정설치된 슬라이더(5)에 삽입설치되며, 고정구(2')에 연결설치된 작동암(2)의 하방에는 유압 및 스프링의 원리를 이용한 통상의 닫힘장치(6)가 고정설치되어 이루어진 것이다. 이러한 종래의 장치는 도어(11)가 개방됨과 동시에 고정구(3')를 중심으로 상향회동된 작동암(2)을 유압 및 스프링의 원리를 이용한 복잡한 구조의 닫힘장치(6)로 하향회동시켜 줌으로서 도어(1)를 자동적으로 닫아주도록 구성된 것으로 도어(1)의 개폐작동과정을 간략하게 살펴보기로 한다.Conventionally, as shown in FIG. 1, the automatic closing device of the sliding door 1, which has been mounted and used in various railway vehicles, has one side of the operating arm ARM 2 of the appropriate length on the side of the vehicle body 3 side. The roller 4, which is connected to the fixture 3 'in a rotatable state and is mounted on the other end of the operating arm 2, is inserted into and installed in the slider 5 fixed to the door 1 side, and the fixture 2 Under the operating arm (2) connected to the installed ') is made of a conventional closing device 6 is fixedly installed using the principle of hydraulic pressure and spring. This conventional device allows the operating arm (2) pivoted up around the fixture (3) at the same time as the door (11) is opened and pivoted down to the closing device (6) of a complicated structure using the principle of hydraulic and spring. As will be configured to automatically close the door (1) as a brief look at the opening and closing operation of the door (1).
도어(1)를 개방시키게 되면, 끝단의 로울러(4)가 슬라이더(5) 내측에 끼워진 상태인 작동암(2)이 고정구(3')를 중심으로 상향회동됨과 동시에 작동암(2)의 하방에 고정설치된 닫힘장치(6)가 작동되게 되면서 일정한 유압력 및 스프링의 탄발력이 닫힘장치(6)의 내부에서 발생되게 되며, 이와같은 상태에서 도어(1)가 가하던 개방압력(수동 또는 자동)을 제거하게 되면 닫힘장치(6)에 발생되고 있는 소정의 유압력 및 스프링의 탄발력에 의해 작동암(2)이 하향회동하게 되면서 도어(1)를 밀어주게 되어 결과적으로는 개방되었던 도어(1)가 자동적으로 닫혀지게 되는 것이다.When the door 1 is opened, the operation arm 2 in which the roller 4 at the end is fitted inside the slider 5 is pivoted upward with respect to the fixture 3 'and at the bottom of the operation arm 2 at the same time. As the closing device 6 fixed to the door is operated, a constant hydraulic force and spring force are generated inside the closing device 6, and in this state, the opening pressure applied by the door 1 (manual or automatic). ) When the operation arm 2 is rotated downward by the predetermined hydraulic force and spring force generated by the closing device 6, the door 1 is pushed, and as a result, the door ( 1) is automatically closed.
이상에서 살펴본 바와같이 유압력 및 스프링의 탄발력을 이용하여 개방되었던 도어(1)를 자동적으로 닫아주도록 한 종래의 장치는 그 구조자체가 복잡한 관계로 제작단가가 매우 고가인 단점을 안고 있었음은 물론, 도어(4)의 개폐작동이 수없이 반복되게 되면서 구성부품이 쉽게 마모될 수 밖에 없는 관계로 기름이 새거나 스프링의 탄발력이 저하되는 등의 빈번한 고장 발생으로 인해 잦은 유지보수 작업이 필요하게 되는 번거로움이 대두되고 있었다.As described above, the conventional apparatus for automatically closing the door 1 that has been opened by using the hydraulic force and the spring force of the spring had a disadvantage that the manufacturing cost was very expensive due to its complicated structure. As the opening / closing operation of the door 4 is repeated many times, frequent maintenance work is required due to frequent failures such as leaking oil or deterioration of the spring force of the components due to the fact that components can be easily worn. Hassle was on the rise.
본 고안은 이와같은 종래의 문제점을 감안하여 이를 해소하고자 안출한 것으로서, 적절한 무게를 갖는 밸런스웨이트를 이용한 단순원리의 닫힘장치를 작동암의 하방에 고정설치하여 작동암과 함께 회동작동되도록 함으로서, 상향회동 되었던 작동암이 밸런스 웨이트의 하중에 의해 하향회동됨에 따라 개방된 상태인 도어가 자동적으로 닫혀지도록 구성하여 닫힘장치의 제작단가를 대폭적으로 절감시킴은 물론 고장의 요소를 완전히 배제하여 유지보수 관리가 필요없이 반영구적으로 자체기능이 유지되도록 한 슬라이딩 도어의 닫힘장치를 제공함에 있는 것이다.The present invention has been devised to solve this problem in consideration of such a conventional problem, by fixing the closing device of the simple principle using a balance weight having an appropriate weight to the lower side of the operating arm to be rotated with the operating arm, upward As the operating arm rotated downward by the load of the balance weight, the door which is open is automatically closed to reduce the manufacturing cost of the closing device, and also completely eliminates the element of failure and maintains the maintenance. It is to provide a closing device of the sliding door to maintain its function semi-permanently without the need.
이하에서 본 고안을 첨부도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제 2 도 내지 제 4 도에 도시된 바와같이, 주로 철도차량에 설치되는 슬라이딩 도어(11)의 자동 닫힘장치를 형성함에 있어서, 차체프레임(15)의 중앙적정부위에는 보스(16) 보울트(16')로 고정설치된 고정판(17)을 고정설치하여 상기 고정판(17)의 보스(16)에 자유롭게 회동되게 샤프트(18)를 플레이트(19) 및 너트(20)로 고정설치하고 상기 샤프트(18)의 일측면에는 적정형태 및 무게를 갖는 판상의 밸런스 웨이트(21)를 다수의 보울트(22)로 고정설치하며, 슬라이딩 도어(11)의 일측상부에 고정설치된 슬라이더(14)내에는 샤프트(18)의 일측단에 적정길이의 작동암(12) 일측단이 고정설치되고 작동암(12) 타측단의 절곡부(12')에 장착된 로울러(13)가 삽입설치되어 상, 하로의 유동이 자유롭게 이루어지도록 된 것이다.As shown in FIG. 2 to FIG. 4, in forming the automatic closing device of the sliding door 11 mainly installed in the railway vehicle, the boss 16, the bolt 16 on the central position of the body frame 15 Fixed to the fixed plate (17) and fixed to the boss (16) of the fixing plate 17, the shaft 18 is fixed to the plate (19) and the nut (20) and the shaft (18) The plate-shaped balance weight 21 having a proper shape and weight is fixed to one side of the bolt 22, and the shaft 18 is fixed to the upper side of the sliding door 11. One end of the working arm 12 of the appropriate length is fixedly installed at one end of the roller, and a roller 13 mounted at the bent portion 12 'of the other end of the operating arm 12 is inserted and installed to freely move up and down. It is to be done.
미셜명부호 23는 밸런스 웨이트(21)의 회동위치를 제어하면 충격하중을 완화시켜주는 기능을 갖게되는 완충편을 나타낸 것이다.The reference numeral 23 denotes a cushioning piece having a function of relieving the impact load when the rotational position of the balance weight 21 is controlled.
이와같은 구성으로 이루어지는 본 고안의 장치는, 적정무게의 밸런스 웨이트(21)를 이용하는 단순원리의 닫힘장치로 개방된 상태인 슬라이딩도어(11)가 자동적으로 닫혀지도록 이루어진 것이다. 제 2 도에 도시된 바와같이, 슬라이딩도어(11)가 개방되면 절곡부(12') 끝단의 로울러(13)가 슬라이딩도어(11)의 슬라이더(14) 내측에 끼워진 상태인 작동암(12)이 상향회동되게 되고, 그에따라 다수의 보울트(22)에 의해 일체화된 상태인 밸런스 웨이트(21)와 샤프트(18) 역시 보스(16)를 중심으로 하여 동시에 회동되게 된다.The device of the present invention having such a configuration is configured to automatically close the sliding door 11 in an open state by a simple principle closing device using a balance weight 21 of appropriate weight. As shown in FIG. 2, when the sliding door 11 is opened, the operating arm 12 in which the roller 13 at the end of the bent portion 12 'is fitted inside the slider 14 of the sliding door 11. This is to be rotated upward, accordingly, the balance weight 21 and the shaft 18, which are in a state of being integrated by a plurality of bolts 22, are also rotated at the same time around the boss 16.
이때, 편중된 상태로 샤프트(18)에 고정설치된 상태인 밸런스 웨이트(21)가 일정각도 만큼 상향회동 되면서 발생되는 밸런스 웨이트(21)의 자체 하중이 작동암(12)에 전달되고 있는 상태가 유지되게 되는데, 슬라이딩도어(11)를 개방시키던 압력(수동 또는 자동)이 소멸되게 되면 밸런스 웨이트(21)의 하중에 의해 작동암(12)이 하강회동하게 되므로서, 결과적으로는 슬라이딩도어(11)가 밀리게 되면서 닫혀지게 되는 것이다.At this time, the state in which the self-load of the balance weight 21 generated while the balance weight 21, which is fixed to the shaft 18 in a biased state, is rotated upward by a predetermined angle, is transmitted to the operating arm 12. When the pressure (manual or automatic) for opening the sliding door 11 is dissipated, the operating arm 12 is rotated downward by the load of the balance weight 21, and as a result, the sliding door 11 Will be closed as it is pushed.
이상에서 상술한 바와같이 본 고안의 장치는 밸런스 웨이트(21)의 자체 하중만을 이용하여 개방된 상태인 슬라이딩도어(11)를 자동적으로 닫아주도록 함으로서, 전술한 바와같은 종래의 닫힘장치가 내포하던 제반 문제점을 완전히 해소하고, 그 구조가 단순하여 제작비를 대폭절감시키게 될 뿐만 아니라 설치작업 역시 간편히 행할 수 있게 되며, 고장의 요소를 완전히 배제하여 유지관리가 용이하게 되는 실용적이면서도 높은 경제성을 갖는 유익한 고안인 것이다.As described above, the device of the present invention automatically closes the sliding door 11 in an open state by using only its own load of the balance weight 21, so that the conventional closing device as described above is included. Completely solve the problem, the structure is simple, not only greatly reducing the production cost, but also the installation work can be easily performed, and it is a beneficial design with a practical and high economical efficiency that is easy to maintain by completely eliminating the factor of failure will be.
