Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a railway vehicle in which a side window is enlarged while securing rigidity of a window opening to improve a view service for passengers.

[0002]

2. Description of the Related Art At present, in a structure of a semi-monocoque structure used in many railway vehicles, an outer plate joined with a bone member bears a load applied to a vehicle body to secure rigidity. However, recently, from the viewpoint of providing view services to passengers, there is a strong tendency to make the side windows larger and make them continuous windows.
This trend is expected to continue in the future. However, in the above-described structure, it is necessary to secure a certain degree of rigidity in the window opening at the outer plate of the blow-in portion, and thus there is a limit in increasing the size of the side window. In addition, there is a problem in terms of weight, for example, it is necessary to increase the plate thickness as the outer plate area is reduced.

For this reason, as shown in Japanese Utility Model Laid-Open Publication No. 61-161166, a triangular blower integral with the curtain plate and a triangular blower integral with the waist plate are connected by a pin joint at the center of the blower part. By reducing the sharing of bending moment and shear force, the width of the blower is reduced, and as shown in Japanese Utility Model Application Laid-Open No. 61-174376, a transparent hollow member is used for the window opening. A continuous window is formed by arranging a tension-adjustable wire inside the constructed window post, or a continuous window is formed by an outer transparent plate and an inner transparent plate, and tension is applied between both transparent plates. Some have adjustable wires.

[0004]

However, in the former structure in which the triangular blowers are pin-connected, the width of the blower portion is reduced, but the enlargement of the side window is limited. Further, the latter structure composed of a transparent hollow member and a wire has a problem in securing rigidity, and in particular, the wire cannot bear a compressive load. Moreover, as a future subject, it is expected to provide a view obliquely below the vehicle, but the weight of the current semi-monocoque structure will increase significantly.

Accordingly, the present invention provides a railway vehicle capable of increasing the size of a window while securing the rigidity of the window opening, and increasing the rigidity below the window opening to form a continuous window in place of an outer plate. The purpose of the present invention is to provide a structural structure.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a railway vehicle body structure in which a plurality of window pillars are provided in a window opening formed in a side structure. A horizontal bone member in the longitudinal direction of the vehicle body and a vertical bone member in the vertical direction of the vehicle body are combined and configured.
And, it is characterized in that adjacent window pillars are provided symmetrically with a vertical line interposed therebetween with alternately inclined directions, and the side frame is formed by obliquely attaching a vertical frame member of a vehicle waist below the window opening. In addition, adjacent vertical bone members are provided symmetrically with respect to a vertical line, with the inclination directions alternated.

The vertical bone members 31 are arranged diagonally and the inclination direction is alternately arranged, and the adjacent vertical bone members 31, 31 are arranged symmetrically with respect to the vertical line. It is provided in a so-called truss-like structure that is brought close.

As described above, the provision of the truss-structured vertical bone member 31 allows the vertical bone member 31 to efficiently bear the vertical and front-rear directions of the vehicle body, and has the same weight as the conventional semi-monocoque side structure. It is possible to improve the rigidity by forming the lower window opening 32 below the window opening 9, and by providing the window glass 33 outside the vehicle body of the vertical bone member 31, it is limited to a part of the cabin. Instead, the lower continuous window 34 can be formed over the entire length of the cabin.

The structure of the above embodiments can be designed in common with a conventional vehicle. Therefore, even when a vehicle having such a structure is incorporated in a conventional vehicle, only the side structure is newly designed. The design cost can be reduced.
The window post 19 and the bone member 32 are a standard 40 mm square hollow pipe made of stainless steel, and have a wall thickness of 2 to 4 mm.
The inclination angle of the window post 20 is preferably about 45 degrees.
