In particular, the torsional moment is reduced when opening and closing the folding door, and the durability of the door is improved, and the number of parts used when opening and closing the folding door is reduced, thereby reducing the cost and improving productivity. The folding door of the bus as possible.

일반적으로, 버스의 도어는 도어본체가 한 개로 이루어진 스윙도어(swing door)와 두 개로 이루어진 폴딩도어(folding door)로 분류되는 바, 본 명세서에서는 폴딩도어에 대해서 설명하기로 한다.In general, the door of the bus is classified into a swing door consisting of one door body and a folding door consisting of two bars, and thus, the folding door will be described.

종래의 폴딩도어는 도 1 내지 도 3에 도시된 바와 같이, 제1도어본체(1)와 제2도어본체(2)로 이루어져 있으며, 상기 제1도어본체(1)와 제2도어본체(2)는 다수개의 도어힌지(3)에 의해 회전가능하도록 결합되어 있고, 상기 제1도어본체(1)는 다수개의 도어힌지(4)를 매개로 윈도우필러(5)에 회전가능하도록 결합되어 있다.The conventional folding door is composed of a first door body 1 and a second door body 2, as shown in Figures 1 to 3, the first door body 1 and the second door body (2) ) Is rotatably coupled by a plurality of door hinges (3), and the first door body (1) is rotatably coupled to the window pillar (5) via a plurality of door hinges (4).

그리고, 상기 제1도어본체(1)에는 소정크기의 도어엔진브라켓트(6)가 횡방향으로 가로지르도록 설치되어 있고, 이 도어엔진브라켓트(6)에는 압축공기를 이용하여 제1도어본체(1)를 밀고당김으로서 제2도어본체(2)를 회전시켜 폴딩도어를 개폐시키도록 된 도어엔진(7)이 결합되어 있다.The first door body 1 is provided with a door engine bracket 6 of a predetermined size to cross in the lateral direction, and the door engine bracket 6 is provided with compressed air and the first door body 1 by using compressed air. The door engine 7 is coupled to open and close the folding door by rotating the second door body 2 by pushing and pulling).

또한, 상기 제2도어본체(2)에는 폴딩도어를 수동으로 개폐시킬 때 사용하도록 된 봉형상의 핸드레일(8)이 한 개는 횡방향으로 가로지르도록 설치되어 있고 다른 한 개는 대각선방향으로 가로지르도록 설치되어 있다.In addition, the second door body (2) is provided with a rod-shaped handrail (8) which is used to manually open and close the folding door so that one crosses in the transverse direction and the other crosses in the diagonal direction. It is installed to shout.
