Description

  The present invention relates to a balustrade of a passenger conveyor provided upright on an upper surface of a main frame (truss).

  Generally, the balustrade design of a passenger conveyor is divided into one using a transparent balustrade panel such as a glass panel and one using an opaque balustrade panel such as a metal panel.

  In the balustrade of a passenger conveyor using a transparent balustrade panel, for example, as shown in Patent Document 1, the lower end portion of the balustrade panel is sandwiched by panel holding members arranged at intervals in the longitudinal direction of the main frame, The balustrade panel is held upright. A handrail guide rail is fitted and attached to the upper end of the balustrade panel. Further, an outer deck board is attached to the panel holding member so as to be adjacent to the lower end portion of the balustrade panel. In such a configuration, the balustrade panel basically bears the balustrade strength and rigidity.

  Next, in a railing of a passenger conveyor using an opaque-type balustrade panel, for example, as shown in Patent Document 2, handrail guide rails are provided at the upper ends of a plurality of columns arranged at intervals in the longitudinal direction of the main frame. A main deck (handrail guide rail base) and an outer deck board are attached. A balustrade panel is attached between the main deck and the skirt guard. In such a configuration, the strength and rigidity of the balustrade are basically borne by the struts, the handrail guide rails, and the main deck, and the balustrade panel is used as a lid for closing between the main deck and the skirt guard. In this case, the balustrade panel is made of a thin metal plate.
