Description

This disclosure relates to door pocket panels for railway vehicles. Patent Document 1 describes a door pocket panel for a railway vehicle. As shown in Figure 6(a) of Patent Document 1, a so-called "bone-skin structure" is sometimes employed in the door pocket panel of a railway vehicle, where a frame made of structural steel, etc., is bonded to a melamine decorative panel, etc. Japanese Patent Publication No. 2011-131628 This is a plan view showing a metal plate of a door pocket panel of a railway vehicle according to the first embodiment of this disclosure.This is a plan view showing a metal plate of a door pocket panel of a railway vehicle according to a second embodiment of the present disclosure.(a) is a figure showing the results of analyzing the amount of deflection of the door pocket panel of a railway vehicle according to the first embodiment, and (b) is a figure showing the results of analyzing the amount of deflection of the door pocket panel of a railway vehicle according to the second embodiment.(a) is a figure showing the results of the analysis of the amount of deflection of the door pocket panel according to Comparative Example 1, and (b) is a figure showing the results of the analysis of the amount of deflection of the door pocket panel according to Comparative Example 2.(a) is a figure showing the results of the analysis of the amount of deflection of the door pocket panel according to Comparative Example 3, and (b) is a figure showing the results of the analysis of the amount of deflection of the door pocket panel according to Comparative Example 4.(a) is a figure showing the results of the analysis of the amount of deflection of the door pocket panel according to Comparative Example 5, and (b) is a figure showing the results of the analysis of the amount of deflection of the door pocket panel according to Comparative Example 6. A preferred embodiment of a railroad vehicle door pocket panel relating to one aspect of this disclosure will be described in detail below with reference to the drawings. [First Embodiment] Figure 1 is a plan view showing a metal plate of a door pocket panel for a railway vehicle according to the first embodiment of the present disclosure. The door pocket panel 1 is a plate-shaped member used in the door pocket of a railway vehicle, and is a panel that forms a door pocket by being attached to the side structure (not shown) of the railway vehicle. The door pocket panel 1 is a panel located on the passenger compartment side of the railway vehicle in the part where the passenger door is housed when the passenger door for boarding and alighting in the railway vehicle is open. The door pocket panel 1 includes a metal plate 2 extending in a first direction D1 corresponding to the height direction of the railway vehicle, and in a second direction D2 perpendicular to the first direction D1. The metal plate 2 has a vertically elongated shape, for example, corresponding to the shape of the passenger door. In this embodiment, the metal plate 2 is rectangular, and the length in the first direction D1 is greater than the length in the second direction D2. The metal plate 2 is made of, for example, an aluminum alloy. The thickness of the metal plate 2 is, for example, about 3.0 mm to 5.0 mm. In the door pocket panel 1, for example, a decorative panel (not shown) may be attached to one side of the metal plate 2. The decorative panel is attached, for example, to the side of the metal plate 2 facing the passenger compartment of the railway vehicle. Interior components, such as those placed inside the passenger compartment of the railway vehicle, are attached to the decorative panel. These interior components include, for example, the ends of handrails, parts of the edges of partition panels, parts of the seat frames of long seats, and frame members for advertising displays. The components attached to the decorative panel are not limited to the above-mentioned interior components; for example, they may be part of the side wall constituting a train toilet, or part of the side wall constituting an equipment room. The metal plate 2 has a pair of side edges 2a and 2b extending in a first direction D1, and an upper edge 2c and a lower edge 2d extending in a second direction D2. When applying the door pocket panel 1 to a railway vehicle, the side edges 2a and the upper and lower edges 2c are fixed to the railway vehicle's structure. The side edge 2b of the metal plate 2 is not fixed and forms part of the opening through which the passenger door is housed. The metal plate 2 is provided with a mounting area A for attaching interior components of a railway vehicle. Mounting area A is the area where fixing members for attaching the interior components are attached. The aforementioned interior components are fixed to the metal plate 2 via a decorative panel and the fixing members. The fixing members are bonded to the mounting area A of the metal plate 2, for example, with an industrial adhesiv
