BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a two-story vehicle structure. Here, the vehicles include, for example, passenger transportation vehicles such as railroad vehicles, buses, and other passenger transportation vehicles.

[0002]

2. Description of the Related Art Since a vehicle having a two-story structure has to be constructed in a restricted space, the layout of the passenger compartment and the equipment attached thereto is more complicated than that of an ordinary vehicle. For example, in a railroad car, the compartment between the trucks arranged in the front and rear in the longitudinal direction of the vehicle body is a two-story guest room, and the compartment at the end where the truck is located is a one-story guest room or equipment room,
It is common to arrange an air conditioner on the upper part.

As an example of the prior art, Japanese Patent Laid-Open No. 2805/1990
There are those described in Japanese Patent Laid-Open No. 5 and Japanese Patent Laid-Open No. 3-109960.

Here, their specific structures will be described.

FIG. 13 shows a typical example of the cabin structure of the existing two-story vehicle. As shown in the figure, the left and right sides of the roof of the vehicle 100 are low, and the upper floor passenger room 101U
From the left side entrance 102L of the middle floor 102, go up the spiral staircase 103 in the clockwise direction and go out to the center of the vehicle body where the ceiling height is the maximum. There is a passage 105U here. The spiral staircase 103 requires a small area for construction, and seats 106U can be provided on both sides of the passage 105U, so that the number of seats can be increased.
Similarly, to the guest room 101D on the lower floor, the right entrance 10 on the middle floor 102
From the 2R, go down the spiral staircase 104 in the counterclockwise direction and walk through the central passage 1
Go to 05D. Seats 106 are located on both sides of the aisle 105D on the lower floor.
At D, the floor of the seat 106D except the passage 105D is a raised floor, and electric power, command control,
A space for arranging information communication or wire tubes such as compressed air or an air conditioning duct is provided. In this way, the spiral staircases 103 and 104 are used in order to directly enter the passages 105U and 105D where the ceiling height can be made high.

FIG. 14 shows an example of a cabin structure of another existing two-story vehicle, which is a seat 116U of the vehicle 110.
116D are on both sides of each passage 115U / 115D, as in the previous example. To the guest room 111U on the upper floor, there is a straight central stairway 113 from the central entrance 112C in the center of the vehicle on the middle floor 112.
It goes up to the end of the passage 115U. To the guest room 111D on the lower floor, descend from the right side entrance 112R of the middle floor 112 through a straight side stair 114 provided beside the central stair 113. However, since the passage 115D on the lower floor is located in the central portion of the vehicle body, a people trap 115e is provided under the stairs and connected to it. In order to secure the ceiling height at the hangar 115e,
It is not a fried floor.

Further, FIG. 15 shows an example of an existing two-story vehicle. This vehicle 120 has a side window 128.
Since the opening height H _{W of} 129 is large, the guest room 125 on the upper floor,
The guest room 126 on the lower floor has a wide field of view and provides an open living environment. On the other hand, since the lower edge height H _L of the side window 129 on the lower floor is smaller than the height H _F to the floor of the middle floor 122, when there is a longitudinal member that constitutes the vehicle body, the longitudinal member 1 indicated by hatching is shown.
The step portion 127a is formed at 27, and the efficiency with respect to the external force in the front-back direction is poor.

FIG. 16 also shows an example of another existing two-story vehicle, but this vehicle 130 has no problem in the structure of the longitudinal member 137 shown by hatching. But,
Since the lower edge height H _L of the side window 139 of the lower floor guest room 136 is larger than the lower edge height H _U of the side window 138 of the upper floor guest room 135, the opening height H of the side window 139 of the lower floor is higher. Side window 138
Is smaller than the opening height H _W. As a result, the seats on the lower floors are closed compared to the upper floors, which are open, resulting in a living environment that is tight and tight.
