일반적으로 버스의 차체에는 다수의 루프벤트가 설치되어 있어 필요시 상기 루프벤트를 열고 환기를 시킬 수 있도록 이루어져 있다. In general, a plurality of roof vents are installed in a vehicle body so that the roof vent can be opened and ventilated when necessary.

종래의 루프벤트는 도 1에 도시된 것과 같이 평상시 루프벤트(1)를 닫은 상태에서는 상단(2)과 하단(3)이 접촉되어 있어 외부의 공기가 버스내부로 유입되지 못하게 되며, 승객이나 운전자가 실내를 환기시키기 위하여 루프벤트(1)를 상방으로 밀면, 상단(2)과 하단(3)사이에 설치된 지지부(4)의 하부가 중심부로 모아지면서 상단(2)이 위로 이동하여 이렇게 벌어진 상단(2)과 하단(3)사이로 공기가 유입될 수 있었다.In the conventional roof vent, as shown in FIG. 1, when the roof vent 1 is normally closed, the upper end 2 and the lower end 3 are in contact with each other, thereby preventing outside air from entering the inside of the bus. Pushes the roof vent (1) upward to ventilate the room, the lower part of the support (4) installed between the upper end (2) and the lower end (3) is gathered to the center and the upper end (2) is moved upward so Air could flow between (2) and the bottom (3).

그러나 종래에는 버스의 루프에 설치된 루프벤트(1)를 열거나 또는 닫기 위하여 운전자나 승객중 누군가가 루프벤트(1)를 위로 밀던가 아래로 당겨주어야하여 불편함이 있는 문제점이 있다..However, conventionally, in order to open or close the roof vent 1 installed in the roof of the bus, there is a problem that somebody of the driver or the passenger has to push the roof vent 1 upward or pull down the inconvenience.

When the driver presses a button to turn on the switch, the loop vent is automatically opened and the button is pressed to switch off the loop automatically. It is an object of the present invention to provide a device for closing the vent.

상기와 같이 구성된 본 발명의 동작을 살펴보면 다음과 같다.Looking at the operation of the present invention configured as described above are as follows.

도 3은 본 발명에 따른 루프벤트 개폐장치의 닫힌상태가 도시된 작동상태도이고, 도 4는 본 발명에 따른 루프벤트 개폐장치의 열린상태가 도시된 작동상태도이다.3 is an operating state diagram showing a closed state of the roof vent opening and closing device according to the present invention, Figure 4 is an operating state diagram showing an open state of the roof vent opening and closing device according to the present invention.

루프벤트가 닫힌상태에서는 상기 제1밸브(81)는 클로즈, 상기 제2밸브(82)는 오픈, 상기 제3밸브(83), 제4밸브(84)는 클로즈된 상태이다. 즉, 상기 에어챔프(65)내의 공기에 의한 압력이 상기 탄성체(E)의 탄성력보다 크기 때문에 상기 루프벤트는 닫힌상태에 있게된다.When the roof vent is closed, the first valve 81 is closed, the second valve 82 is open, and the third valve 83 and the fourth valve 84 are closed. That is, since the pressure by the air in the air chamber 65 is greater than the elastic force of the elastic body (E), the loop vent is in a closed state.

탑승자가 상기 루프벤트(R)를 열기 위해 스위치를 누르면, 상기 전원(G)의 전기에 의해 상기 제2밸브(82)가 클로즈된다. 상기 제2밸브(82)가 닫히면 상기 에어컴프레셔(71)의 공기가 상기 에어챔버(65)로 유입되지 않는다.When the occupant presses a switch to open the roof vent R, the second valve 82 is closed by electricity of the power source G. When the second valve 82 is closed, air of the air compressor 71 does not flow into the air chamber 65.

이후, 상기 제1밸브(81)가 오픈되면, 상기 에어챔프(65)내의 공기가 상기 배출파이프(75)를 따라 외부로 배출된다. 상기 에어챔프(65)내의 공기배출에 의해 상 기 공기압이 떨어지면, 상기 탄성체(E)의 탄성력에 의해 상기 제1회동부재(51) 및 상기 제2회동부재(53)가 회동된다.Thereafter, when the first valve 81 is opened, air in the air chamber 65 is discharged to the outside along the discharge pipe 75. When the air pressure drops due to the air discharge in the air chamber 65, the first rotating member 51 and the second rotating member 53 are rotated by the elastic force of the elastic body E.

이때, 상기 제1피스톤(61)과 제2피스톤(63)이 상기 실린더(60) 내부로 밀려들어와서 상기 제1회동부재(51)와 상기 제2회동부재(53)가 수평상태를 이루게된다.At this time, the first piston 61 and the second piston 63 are pushed into the cylinder 60 so that the first rotating member 51 and the second rotating member 53 are in a horizontal state. .

상기 제1회동부재(51)와 상기 제2회동부재(53)가 수평상태가 되면, 상기 제어부의 신호에 의해 상기 제1밸브(81)가 클로즈되고, 상기 제2밸브(82)는 오픈상태가 된다. 즉, 상기 에어컴프레셔(71)의 공기가 상기 에어챔프(65)내에 유입되어 상기 에어챔프(65)는 공기압을 얻게된다.When the first rotating member 51 and the second rotating member 53 are in a horizontal state, the first valve 81 is closed by a signal of the controller, and the second valve 82 is in an open state. Becomes That is, the air of the air compressor 71 is introduced into the air chamber 65 so that the air chamber 65 obtains air pressure.

상기 에어챔프(65)의 공기압에 의해 상기 제1회동부재(51)와 상기 제2회동부재(53)가 위쪽으로 계속 회동하여 상기 제1피스톤(61)과 상기 제2피스톤(63)은 상기 실린더(60) 밖으로 돌출하게 된다.The first pivot member 51 and the second pivot member 53 continue to rotate upward by the air pressure of the air chamber 65 so that the first piston 61 and the second piston 63 It protrudes out of the cylinder 60.

물론 상기 제1회동부재(51)와 제2회동부재(53)의 회동에 의해 상기 실린더(60)가 상승하게되고, 따라서 상기 실린더와 결합된 상기 루프벤트(R)도 위쪽으로 상승하게 된다. 즉, 상기 루프벤트(R)가 열리게 된다.Of course, the cylinder 60 is raised by the rotation of the first rotating member 51 and the second rotating member 53, so that the roof vent R coupled with the cylinder is also raised upward. That is, the loop vent R is opened.

다음, 상기 루프벤트(R)를 닫기위해 상기 탑승자가 스위치를 누르면, 상기 제2밸브(82)가 닫히고 상기 제1밸브(81)가 열리게된다. 즉, 상기 에어챔버(65)내의 공기가 상기 배출파이프(75)를 통해 외부로 배출된다.Next, when the occupant presses the switch to close the roof vent R, the second valve 82 is closed and the first valve 81 is opened. That is, the air in the air chamber 65 is discharged to the outside through the discharge pipe 75.

동시에 상기 제2밸브(83) 및 제4밸브(84)가 열려 상기 에어컴프레셔(71)의 공압에 의해 상기 제1회동부재(51)와 상기 제2회동부재(53)를 아래쪽으로 회동시킨다. 즉, 상기 제1회동부재(51)와 상기 제2회동부재(53)가 아래쪽으로 회동되어 상 기 제1회동부재(51)와 상기 제2회동부재(53)가 수평상태가 되면, 상기 제3밸브(83)와 상기 제4밸브(84)가 닫히고 상기 제2밸브(82)는 열리고 상기 제1밸브(81)는 닫히게 된다.At the same time, the second valve 83 and the fourth valve 84 are opened to rotate the first rotating member 51 and the second rotating member 53 downward by the pneumatic pressure of the air compressor 71. That is, when the first rotating member 51 and the second rotating member 53 are rotated downward so that the first rotating member 51 and the second rotating member 53 are in a horizontal state, the first rotating member 51 and the second rotating member 53 are horizontal. The third valve 83 and the fourth valve 84 are closed, the second valve 82 is opened, and the first valve 81 is closed.

따라서, 상기 에어컴프레셔(71)의 공기가 상기 에어챔버(65)에 유입되어 상기 에어챔버(65)에 가해진 압력에 의해 상기 제1회동부재(51)와 상기 제2회동부재(53)가 계속 아래쪽으로 회동된다.Accordingly, the air of the air compressor 71 flows into the air chamber 65 and the first rotating member 51 and the second rotating member 53 continue to be driven by the pressure applied to the air chamber 65. It is rotated downward.

즉, 상기 제1회동부재(51)와 상기 제2회동부재(53)의 회동에 의해 상기 실린더(60)가 하강하게 되고, 상기 실린더(60)에 연결된 상기 루프벤트(R)도 아래쪽으로 하강하여 상기 루프벤트(65)가 닫히게 된다.That is, the cylinder 60 is lowered by the rotation of the first rotating member 51 and the second rotating member 53, and the loop vent R connected to the cylinder 60 is also lowered. The loop vent 65 is closed.

본 발명에 따른 루프벤트 개폐장치는 탑승자가 스위치조작에 루프벤트를 자동으로 손쉽게 개폐시킬 수 있는 장점이 있다.Roof vent opening and closing device according to the invention has the advantage that the occupant can easily open and close the loop vent automatically in the switch operation.
