DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cabin door for a tractor, a combine or the like.

[0002]

2. Description of the Related Art Cabin doors for tractors and the like are disclosed, for example, in Japanese Utility Model Laid-Open No. 63-1899.
As disclosed in Japanese Patent Publication No. 12, a form in which a door reinforcing frame having an upper frame, a vertical frame, and a lower frame is mounted inside a transparent glass in a state where a traveling direction is opened, and door hinges are provided on the reinforcing frame in the vertical direction. Is known.

However, in the above-described embodiment, since the door hinge is provided directly on the reinforcing frame inside the cabin, the impact load cannot be reduced.

[0004]

SUMMARY OF THE INVENTION The present invention is directed to a cabin door in which the glass 37, 47 having a rubber seal 54 fitted and held on its peripheral edge is openably and closably attached to a rear support 24 by a hinge 29. , The hinge 2
9 is fixed to the outer surface of the rear support 24, while the distal end thereof is attached to a mounting seat 50 corresponding to the inside of a mounting hole 49 formed in the glass 37 at a position slightly away from the peripheral edge of the glass 37. It is configured to be tightened and fixed with a bolt 53 with an elastic body 52 interposed.

[0005]

A cabin door in which the glass 37, 47 having a rubber seal 54 fitted and held on the periphery thereof is openably and closably attached to the rear support 24 by the hinge 29, and the base end of the hinge 29 is connected to the rear support 24. An elastic body 52 is interposed in a mounting seat 50 whose front end is slightly away from the peripheral edge of the glass 37 and corresponds to the inside of a mounting hole 49 formed in the glass 37, and a bolt is fixed to the outer surface. By tightening and fixing the hinge 53, the hinge 29 can be formed on the outer surface, and the protrusion into the cabin is eliminated. Further, since the elastic member 52 is interposed and fixed in the mounting hole 49, the impact when the door is opened and closed can be reduced.

DESCRIPTION OF THE PREFERRED EMBODIMENTS ** A tractor body 6 has a front axle bracket 7, a clutch housing 8, a transmission case 9, and the like connected from the front.
The left and right sides of the transmission case 9 are supported by a front axle housing 10 so that the front wheels 11 can be driven. The left and right sides of the transmission case 9 are supported by a rear axle housing 12 so that the rear wheels 13 can be driven. It is configured to be driven in conjunction with the engine 14.

[0007] At the top of the mission case 9 is a cockpit 1
5 and a steering handle 17 at the front of the step floor 16. A floor 19 is provided from the upper fender 18 of the rear wheel 13 to the upper side of the transmission case 9 at the center, and is supported by the lower frame 20 with respect to the transmission case 9 to the rear axle housing 12.

[0008] The frame structure of the cabin 21 is composed of a front support column 23, a cockpit 15
A front support frame 24 connecting the lower ends of the left and right front supports 23 to each other,
The four corners of the roof frame 1 having a rectangular shape in a plan view are connected between the rear connection frame 26 connecting the lower ends of the left and right rear supports 24 to each other, and between the upper ends of the front supports 23 and the rear supports 24. The front connecting frame 25 is superposed on the dashboard 22 and the rear connecting frame 26 is mounted on the lower frame 20 at the rear of the transmission case 9 so as to be superimposed, and the lower ends of the front support 23 and the rear support 24 on both left and right sides. The parts are connected to each other by a front part and a rear part of the fender 18 and mounted on the vehicle body 6.

A windshield 27 is provided between the front supports 23 of such a cabin 21 frame, a rear glass 28 is provided between the rear supports 24 so as to be openable and closable, and a rear support is provided between the left and right front and rear supports 23, 24. A door 30 is provided to the door 24 so as to be freely opened and closed by a hinge 29. The roof frame 1 is made of sheet metal and is formed hollow by joining and joining an outer member and an inner member, and the outer member is exposed to the outside of the cabin. Also, the inner member is exposed in the cabin.

The front side portion 3 forms a mounting edge 32 at the lower portion on the front side for mounting the upper edge of the windshield 27 via a seal 31, and the rear side edge forms a stepped portion 33. The front edge can be superimposed on the lower edge 34 of the step 33, and can be joined by welding, bolts, nuts, or the like. Further, the left and right side portions 4 are continuously formed in the same manner, and the upper surface is formed narrower than the front side portion 3 so that the amount of rain diverted to the outside is reduced.

The rear side 2 does not form the step 33,
An upper end surface 35 is formed on a surface at the same height as the lower edge portion 34, and a rear edge portion of the roof panel 5 is overlapped on the upper end surface 35 and joined. 36 is a lining board. In addition, the roof frame 1 is assembled and constructed by overlapping A in the form of insertion from the front and rear sides 4 on the left and right sides. In such a configuration, it is possible to assemble with a fastener such as a bolt. In addition, it is possible to share the case where the lengths in the front-back direction are different due to different models.

The door 30 is hinged to the rear support 24 by a hinge 29.
A glass frame 38 made of a thick pipe material and a glass frame 43 made of a pipe material thinner than the glass frame 38 are attached to the glass frame 38 so as to be freely opened and closed. The upper side portion 44 is inserted and polymerized B, and fixed by welding or the like. Further, the lower side portion 42 of the glass frame 38 is inserted and fixed to a door lock bracket 45 located at the middle portion of the glass frame 43, and the lower side portion 46 of the glass frame 43 is connected to the rear portion of the lower side portion 42. I have. The upper side 44 and the lower side of these glass frames 43 have different angles with respect to the lower side 42, and therefore, the upper glass 37 and the lower glass 47 attached to the outside of the glass frame 43 extend along the lower side 42. A seam 48 made of an adhesive or the like is formed to change the angle of the glass surface.

The glass plates 37 and 47 are mounted on the outer surfaces of the glass frames 38 and 43 with an elastic body such as rubber interposed therebetween, and are fixed to hinges 29 and corners of the glass frame 43 and the like. 50 and 45 parts of the door lock bracket. In the mounting seat 50, a stepped nut 51 and an elastic body 52 fitted on the outer periphery of the mounting hole 49 formed in the glass 37, 47 are fitted to fit the stepped nut 51 and the mounting seat 50. Is fixed with a bolt 53.

The peripheral edges of the glasses 37 and 47 with respect to the door lock bracket 45 are fitted and held via rubber seals 54. The outer peripheral edges of the glass 37, 47 project outward beyond the glass frames 38, 43, and a seal damper 55 is attached. When the door is closed, the cabin 21 is closed.
The seal receiving edge provided on the frame side, the lower edge portion 39 of the left and right side portions 4 of the roof frame 1 and the like are brought into contact with each other to maintain airtightness.

The front edge 5 of the door lock bracket 45
6, a door lock bracket 45 is provided inside a seal damper 55 attached to the front side edge of the lower glass 47.
A drain passage 59 communicating with the inside of the housing 57 and the drain hole 58 is formed in a series, and the water that has entered the inside of the door lock bracket 45 is guided downward to drain from the drain hole 60 formed in the seal damper 55 at the lower end. I do.
