Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an entrance / exit door device for a cabin of a moving vehicle that opens and closes in the front-rear direction.

[0002]

2. Description of the Related Art Conventionally, in a moving vehicle having a cabin room at an intermediate portion in the front-rear direction of the machine body, a door for a driver to get on and off is attached to the side of the cabin room, and the door is opened laterally to widen the machine body. I am getting on and off.

[0003]

Such a conventional one requires a width for accommodating an airframe and a space for opening a door, and therefore cannot be stored in a narrow space, and a cabin room is added to a moving vehicle. When installing, the front wall of the cabin is located near the bonnet, which makes it difficult to open the hood, and if the front wall of the cabin is too far away from the end of the bonnet, it becomes a slender cabin space, which makes living difficult. It had drawbacks.

[0004]

The present invention has taken the following technical means in order to solve such a problem of the conventional device. That is, the engine 2 and the bonnet 3 that covers the engine 2 are provided above the left and right front wheels 1, 1 attached to the front of the machine body, and the left and right rear wheels 4, 1 attached to the rear of the machine body.
A seat 5 for seating the driver and a solution tank 6 extending from both sides of the seat 5 to the rear are provided between the front and rear wheels 1.
In a moving vehicle in which the four are connected by a floor 7 and a steering handle 8 is provided at a rear end portion of the bonnet 3 above and in front of the floor 7, from a side portion of the bonnet 3 straddling the bonnet 3. The front wall 9 extending to the upper part and the left and right side walls 10, 10 extending to the upper part from the left and right side edges of the floor 7 are integrated, and the lower part swings back and forth around the upper part as a rotation center. It is configured as an entrance / exit door device for a cabin of a moving vehicle.

[0005]

The present invention has the following technical effects due to the above configuration. That is, the first half of the cabin room straddles the bonnet 3 in a saddle shape.
The front wall 9 extending from the side portion to the upper portion is integrally formed with the left and right side walls 10 and 10 extending from the left and right side edges of the floor 7 to the upper portion. Since the part swings back and forth around the upper part as the center of rotation,
When the driver gets on and off the vehicle, the front half of the cabin, which is an integral part of the vehicle, can be swung forward and upward. Also, when opening the bonnet 3 on the machine side, if the lower part of the cabin room, which is an integral part, is swung forward with the upper part as the center of rotation, there will be no obstacles near the bonnet 3 and it will be easy. Can be opened to.
