Description

【考案の詳細な説明】産業上の利用分野・関連出願この考案は、天井が改良された２階バスに関す
る。[Detailed Description of the Invention] Industrial Field of Application/Related Applications This invention relates to a two-story bus with an improved ceiling.

背景技術および目的・課題従来の２階バスでは、全車高が制限されている
ので、充分に通路面からの天井高さをとることが
困難であつた。BACKGROUND TECHNOLOGY, OBJECTIVES AND PROBLEMS In conventional two-story buses, the total vehicle height is limited, so it has been difficult to maintain a sufficient ceiling height from the aisle surface.

そこで、この考案の目的・課題は、通路面から
の天井高さをより高くし、乗り降りを円滑にする
２階バスの提供にある。 Therefore, the purpose and problem of this invention is to provide a two-story bus that has a higher ceiling height from the aisle surface and allows smooth boarding and alighting.

状に製作された。Explanation of Specific Examples The second floor bus of this invention will be explained below based on the specific examples shown in the drawings.
An embodiment 10 of a two-story bus of the invention is shown in which a plurality of longitudinal steel beams and transverse steel beams 12 support a roof panel (not shown) and Its transverse beam 12
However, in the central part of the ceiling 13 corresponding to the second floor passage 18, the beam thickness is made thinner than in the parts 14 and 15 on both sides of the beam, and the beam width is made wider and the lower surface of the beam is recessed upward. It was manufactured with a cross-sectional shape of .

に横断面形状を変形させた。 As such, the transverse beam 12 has been modified in cross-sectional shape to provide sufficient strength, so that the upper surface of the central ceiling portion 13 and the side beam portions 14, 15, in order to support the roof panel, That is, the outer surfaces are aligned with each other. In other words, the transverse beam 12 extends the neutral plane of the central ceiling portion 13 to both side portions 1 of the beam.
The cross-sectional shape was changed so that it was located further outside than that of Nos. 4 and 15.

Since the ceiling center portion 13 corresponding to the floor passage 18 is deformed in cross section and the lower surface of the beam is recessed upward, the second floor bus 10 has a
The ceiling height from the aisle has been raised, making it easier to get on and off the train.

になる。Convenience/benefits of the invention According to this invention, the horizontal beam in the ceiling above the second-floor passageway is thinner in the central part of the ceiling corresponding to the second-floor passageway than in the beam thickness on both sides of the beam. In addition, since the beam width is widened and the lower surface of the beam is recessed into the upper surface, the ceiling height from the aisle surface becomes higher in the second floor aisle, making it easier for passengers on the second floor of the bus to become mobile and thus facilitate getting on and off the bus.
