Abstract

PURPOSE:To facilitate the opening and closing operation for a door by providing a door handle for opening and closing plural superposed door glass sheets in such a manner as to turn on an opening and closing shaft intersecting perpendicularly to the glass face. CONSTITUTION:In a cabin 10 of a tractor, a combined harvester or the like, plural superposed door glass sheets 1, 2 are turned on an opening and closing shaft 4 intersecting perpendicularly to the glass face to open and close a door. The cabin door is provided with an outside door handle 5 and an inside door handle 6 for opening and closing the door glass sheets 1, 2, which are disposed in such a manner as to turn on the opening and closing shaft 4. The door glass sheets 1, 2 are turned to be opened and closed by turning one of door handles 5, 6 on the opening and closing shaft 4. Accordingly, the door handles 5,6 are placed in substantially fixed positions near the periphery of the opening and closing shaft 4 so as to facilitate its opening and closing operation.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door handle used in a cabin of a tractor, a combine, a crop, a pest control machine or the like.

[0002]

2. Description of the Related Art In a mode in which a door glass of a cabin is opened and closed by rotating it in a direction along the glass surface, a door handle for opening and closing the door glass directly rotates the door glass. If it is installed at a position deviated from the center of motion, the position of the door handle changes with the degree of opening / closing of the door handle, making it difficult to operate.

[0003]

SUMMARY OF THE INVENTION The present invention relates to a cabin door that opens and closes by rotating a plurality of overlapping door glasses 1 and 2 around an opening / closing shaft 4 in a direction orthogonal to the glass surface, A cabin door handle is constructed such that door handles 5 and 6 for opening and closing the door glasses 1 and 2 are provided so as to rotate around the opening / closing shaft 4.

[0004]

When the door glasses 1 and 2 are opened and closed, the outer door handle 5 or the inner door handle 6 is rotated around the opening / closing axis 4 to open the door glasses 1 and 2. It can be opened and closed around the coaxial 4. Therefore, the door handles 5 and 6 can be pivoted at a substantially fixed position near the opening / closing shaft 4, and the opening / closing operation is easy.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A cabin 10 covering the upper part of a tractor body 7 from a steering handle 8 to a cockpit 9 extends from a roof 11 to a windshield 12 to a floor glass 13 on the front of the floor. The door sashes 14 are formed in a semi-cylindrical shape, and arcuate door sashes 14 are provided on both left and right sides of the door sashes 14. The door sashes 14 can guide the outer peripheral edges of the door glasses 1 and 2 and the saddle glass 3 to rotate back and forth. The open / close shaft 4 of the door glasses 1 and 2 is located on the side of the cockpit 9, and the lower end and the upper end of the sash 14 are connected by a floor sash 15, a window sash 16, etc. The door glass 1 and the door glass 1 and the window glass 3 each having a substantially fan shape centered at are appropriately divided into shapes, and the door openings can be opened and closed by pivoting in a pulling manner along these glass surfaces.

An outer door glass 1 is fixed by a bracket 17 to the opening / closing shaft 4 which is integrally rotated by the door handles 5 and 6, and is integrally rotated. The door glass 2 at the center can be interlocked with the opening / closing shaft 4 with the cam pipe shaft 18 interposed, and when the opening / closing rotation angle of the door glass 1 becomes a certain value or more,
The cam pipe shaft 18 can be engaged to rotate the door glass 2 at the center. The inside window glass 3 is independently opened and closed regardless of the door handles 5 and 6.

A friction plate 19 is interposed around the opening / closing shaft 4 between the door glasses 1 and 2 and the mudglass 3 to hold the opening / closing positions of the glasses 1, 2 and 3. Two
Reference numeral 0 is a rear window glass attached to the wind sash 16, which can be opened and closed by using the upper end portion as a hinge. 21 is a chemical solution tank for control, which can be attached and detached from the rear side of the vehicle body 7 so as to fit over the right and left side portions from the rear side of the cockpit 9. The front upper surface is joined to the floor sash 15 of the cabin 10, It can form part of the floor. Reference numeral 22 is a hood of the engine E, and the front portion of the cabin 10 frame and the floor glass portion 14 are configured so as to straddle the hood 22 and the dash board portion 23 left and right.

The cabin 10 is mounted on the vehicle body 7 from the upper side, and is detachably attached and fixed to a frame component member integrated with the vehicle body 7 with attachment pins 24 and 25. Reference numeral 26 is a front wheel that is steered by a steering wheel, and 27 is a rear wheel, which is a four-wheel drive traveling mode driven by an engine E. Reference numeral 28 denotes a spray nozzle provided in front of the vehicle body 7, which sprays the chemical liquid in the chemical liquid tank 21 by driving a pump.

Numeral 29 is a hook pivotally supported 30 at the rear end of the vehicle body 7 so as to be vertically rotatable, and is formed in a left and right loop shape, and is pressed upward by a spring 31. At the bottom of the chemical liquid tank 21, there is a hook 32 that can be engaged with this hook 29,
It also has a caster 33 at the rear end. The loading and unloading of the chemical liquid tank 21 can be facilitated by engaging the hooks 32 and 29. 34 is a hitch.

From the outside of the cabin 10, the door handle 5 is operated to open and close the door glasses 1 and 2 upward and rearward to get on and off. The door handle 6 is operated from the inside to open and close the door glasses 1 and 2. At this time, the rear end of the door sash 14 is opened so that the door glasses 1 and 2 can be opened by projecting and rotating rearward of the rear window sash 15 so that the door opening can be widened.
