【考案の詳細な説明】 この考案はトラクターの如き乗用タイプの動力農機のキ
ャビンドアに関するものである。[Detailed description of the invention] This invention relates to a cabin door for a riding-type power agricultural machine such as a tractor.

作業機を連結して障害物に接近しながら作業を行う場合
の多い動力農機は、キャビンの視界を充分に広く確保す
ると共に、キャビン内の採光も運転操作員の足元に１で
及ぶようにする必要がある。For powered agricultural machinery, where the work equipment is often connected to work while approaching obstacles, the cabin should have a sufficiently wide field of view, and the cabin should be well-lit so that it reaches the operator's feet. There is a need.

What is intended to be provided in this invention, and its structure will be explained based on one embodiment shown in the drawings, is that the center portions of two plates 1 and 2 are cut out 1as2a, and narrow inner peripheral edges 1b and 2b are cut out. and outer periphery 1c, 2
The plates 1 and 2 are subjected to a drawing process, leaving a portion c, respectively, and then the inner peripheral edges 1b, 2b and the outer peripheral edges 1c, 2c are overlapped and fixed together by means such as spot welding. 1b and 2b are formed in the same plane so that the window glass plate 4 can be fitted to the sealing rubber 3 having an H-shaped cross section fitted to the inner peripheral edges 1b and 2b, and the outer peripheral edges 1c and 2c are
A similar sealing rubber 6 is fitted to the upper outer peripheral edge 5, which is the upper side of the outer peripheral edge 1b.
, 2b, there is an intermediate frame portion T having a rectangular box-shaped cross section with its upper half bent inward, and the remaining inner peripheral edge 1b.

２ｂと外周縁１ｃ、２ｃとの間にも直方形箱形断面の戸
当枠部８，９，１０が板１，２の前後部と下部に形成さ
れるようにする。2b and the outer peripheral edges 1c, 2c, doorstop frame parts 8, 9, 10 having a rectangular box-shaped cross section are formed at the front, rear, and lower portions of the plates 1, 2.

そして、角形管又は異形型管などの如き中空型材を角山

板１３が嵌着できるよう構成する。Then, the upper frame 11 is assembled by bending a hollow material such as a square pipe or an irregularly shaped pipe into a square chevron shape.
A door frame is formed by welding the front and rear foot parts 0 to the front and rear ends of the intermediate frame part 1, and the outer peripheral edge upper part 5 is also attached to the soil part frame 11.
An inner peripheral edge 11a is formed in the same plane as the outer peripheral edge upper part 5 and a seal rubber 12 fitted to the inner peripheral edge 11a so that a window glass plate 13 can be fitted onto the seal rubber 12.

たのである。The cabin door according to this invention has the lower half of the door frame cut out 1a, 2a and drawn 2 as described above.
By joining the two plates 1 and 2 together, the sealing rubber 3 is fitted to the mutually joined inner peripheral edges 1b and 2b, making it possible to fit the window glass plate 4, and the cutout 1a, A frame is formed around the frame 2a by the middle frame part 1, which is formed into a box-shaped cross section and has extremely high rigidity, and the doorstop frame parts 8, 9, and 10. Part 7
If it is fixed to the door, it will be strong and the window area will be large, forming a single door with a large field of view, which will cause a large amount of vibration and sway during operation.Also, it will be difficult for power farm machinery to operate with many control levers, etc. This made it suitable for use as a cabin door.

ど、この考案に係るキャビンドアは多くの利点を具備す
るものである。Moreover, in the manufacturing process, the lower half of the door frame can be formed by cutting out a plate, drawing it, and placing it on each other, and the upper half can be formed by forming a hollow member into a frame shape. Since the upper frame 11 can be formed by forming the upper frame 11, the processing and assembly work can be simple, mainly consisting of cutting, drawing and welding, and the cabin door according to this invention is It has many advantages.
