Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cabin and is used for industrial vehicles such as tractors.

[0002]

2. Description of the Related Art As a cabin of a tractor, Japanese Patent Laid-Open No. Sho 62-62
-71719 (Prior art example 1), JP-A-1-273
747 (conventional example 2) and JP-A-4-3178.
Publication No. 17 (conventional example 3) and the like are known.

[0003]

In the conventional example 1, since the skeleton body of the cabin (a pair of left and right front columns, rear columns, a ceiling frame, etc.) is composed of metal pipes, the weight is increased and wet field work is performed. It may cause excessive subsidence and is not suitable for a tractor which is a traveling work vehicle because it compacts the soil.

On the other hand, the conventional example 2 can contribute to weight reduction because it is made of resin with a three-part structure of the front panel, the roof panel and the rear panel. However, the conventional example 2 has a problem that it can be expected to be lighter but is slightly inferior in rigidity. On the other hand, the conventional example 3 is made of resin, and the front grill has a hollow structure to ensure rigidity, but there is a problem that the rigidity of the ceiling part (roof) is slightly inferior.

Therefore, it is an object of the present invention to provide a cabin that is lightweight and secures rigidity, and in particular, can secure the rigidity of a roof together.

[0006]

SUMMARY OF THE INVENTION The present invention is directed to a front perspective member 4
The above object is achieved in a cabin 3 having a front grill 5 having a rear grille 6, a rear strut 6, and a roof 7 extending between the upper portion of the front grille 5 and the upper portion of the rear strut 6. In order to do so, the following technical measures are being taken.

That is, according to the present invention, the skeleton of the front grille 5 is formed by the hollow portion 15, the roof 7 is provided with the reinforcing body 25, and the front and rear of the roof 7 are provided with the front grille 5 and the rear pillars. Connecting means 2 for connecting to 6 respectively
It is characterized by having 7, 28. Further, in the present invention, the roof 7 is the inner roof 23.
And the outer roof 24. At least one of the roofs 23, 24 is formed with a rib 23A, and the rib 23A is used as a reinforcing body 25.
24 can be joined and integrated, and the roof 7
Is a skeleton body 29 and a skeleton body 29 having a planar view frame configuration.
The outer roof 24 is provided on the upper side, and the skeleton body 29 constitutes a reinforcing body 25. The front grille 5 and the rear support column 6 are attached to the front and rear of the skeleton body 29 by connecting means 27 and 28. You can wear it.

[0008]

Operation: The front grille 5 in the cabin 3 according to the present invention
Since the skeleton is formed by the hollow portion 15, the rigidity is ensured by the rib action of the hollow portion 15 even if it is made of resin. On the other hand, the roof 7 is provided with the reinforcement 25,
Rigidity is secured.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 7, which shows the overall configuration, the driving control section 2 of the vehicle 1, which is a two-axis, four-wheel tractor, is surrounded by a cabin 3 according to the present invention. With reference to FIGS. 1, 4 and 8, the cabin 3 has a front grill 5 having a front see-through member 4 made of glass or the like, and a substantially gate shape in a front / rear view, which is erected from a vehicle body or a fender. Rear support 6
And a roof 7 provided over the upper portion of the front grille 5 and the upper portion of the rear support column 6 for easy packaging, transportation and assembly / disassembly.

The front grille 5 is provided with a fitting portion 9 of the bonnet 8 shown in FIG. 7, as shown in FIG.
A skirt portion 10 having small windows is provided on both left and right sides to ensure visibility of the lower front portion. The skeletons of the upper portion 11, the left and right vertical portions 12, the intermediate portion 13, and the lower portion 14 are all hollow portions. The hollow portion 15 acts as a rib to reduce the weight and improve the rigidity.

The hollow portion 15 is composed of inner and outer resin plates 16 and 17 by, for example, a twin compo-jet method, and the rim of the hollow portion 15 is made of the resin plate 1.
6, 17 are overlapped portions and are flat portions, and are formed as a mounting portion of the glass sealing material 18, a mounting portion of the weather strip 19, a connecting portion 20 with the roof, and a lower connecting portion 21.

Furthermore, the inner and outer resin plates 16 made of ABS resin,
By setting 17, it is possible to make the hue and surface hardness different between the indoor side and the outdoor side and improve the quality of the cabin 3. In addition, when forming the hollow portion 15, a nut 22 can be inserted into the connecting portion 20 or the lower connecting portion 21 to prevent the nut 22 from being exposed on the surface.

The roof 7 is made of FRP, and the inner roof 23 and the outer roof 24 are integrally formed by blow molding. In the first embodiment shown in FIG. 1, ribs 23A are formed on the inner roof 23. With reinforcement 2
5, the rear portion has a fitting portion 26 to the rear strut 6, and is attached by connecting means 27 and 28 exemplified by bolts.

In the roof 7 shown in FIG. 8, a skeleton body 29 having a frame structure in a plan view is covered with an outer roof to cover the skeleton body 29.
The sound absorbing material 30 such as a sponge is inserted as an interior material into the skeleton body 29, and the frame body 29 is attached together with the edging presser material 31 by the bolts 32. Has become. Hollow part 15 of upper part 11
4 can be crushed to form a recess 33 as shown in FIG. 4, a wiper motor 34 can be attached to the recess 33 to provide a wiper device 35, and the lower connecting portion 2
As for No. 1, the bush 36 may be inserted into the pin 37 as shown in FIG.

As for the wiper motor 34 and the wiper device 35, as shown in FIG. 5, a motor shaft insertion portion 34A may be formed on the glass which is the transparent body 4, and a bush 34B may be fitted and attached thereto. Furthermore, regarding the rear support 6,
As shown in FIGS. 2 and 3, the interior material 36 and the exterior material 37 may be used as makeup.

Referring to FIG. 6, inner and outer resin plates 16 and 17
In the meantime, an example of a manufacturing means by sandwiching glass as the transparent body 4, mounting it on the lower mold 38, and cooperating with the upper mold 39 by press molding is shown. Further, as shown in FIG. 7, a hood 40 or an opening / closing door may be attached to the left and right entrances / exits of the cabin 3. In addition, the reinforcing member 25 of the roof 7
The outer roof 24 may be formed with ribs.

[0017]

As described above in detail, according to the present invention, the weight and the rigidity are improved, and in particular, the rigidity of the roof is ensured, which is a great benefit as a cabin of an industrial vehicle.
