Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a passenger conveyor capable of preventing falling of the passenger conveyor even when an unfixed side support beam is disconnected from a building side support beam, and capable of preventing damage of a component of a frame bottom part while automatically returning the unfixed side support beam disconnected from the building side support beam again on the building side support beam.SOLUTION: A horizontal part on the side for providing an unfixed side support beam 7 of a frame 4, is provided with a component of a frame bottom part, a slide base 11 projecting downward from the component of the frame bottom part and an additional building beam 5 provided by having a predetermined clearance between the slide base 11 and itself under the frame 4, and the additional building beam 5 supports the frame 4 by allowing the slide base 11 to abut on the additional building beam 5 when the unfixed side support beam 7 is disconnected from the building side support beam 3a by becoming large in a distance between the two building side support beams, and the predetermined clearance is a size capable of returning the unfixed side support beam 7 again.SELECTED DRAWING: Figure 1
【課題】非固定側支持梁が建屋側支持梁から外れた場合でも、乗客コンベアの落下を防止できるとともに、建屋側支持梁から外れた非固定側支持梁が再び建屋側支持梁の上に自動的に戻ることを可能にしつつ、フレーム底部の部品の破損を防ぐことができる乗客コンベアを提供する。【解決手段】フレーム4の非固定側支持梁7が設けられている側の水平部において、フレーム底部の部品と、フレーム底部の部品よりも下方に突出したスライドベース11と、フレーム4の下方に、スライドベース11との間に所定の隙間を有して設けられた追加建築梁5とを有し、追加建築梁5は、2つの建屋側支持梁の間の距離が大きくなって非固定側支持梁7が建屋側支持梁3aから外れた場合にスライドベース11が追加建築梁5に当接してフレーム4を支持するとともに、所定の隙間は、非固定側支持梁7が再び戻ることが可能な大きさである。【選択図】 図1 |
