  • Patent number: 8596445
    Abstract: A balustrade assembly includes a decking panel and a skirt panel that are attached to one another and to a balustrade support structure without fasteners. A positioning device included in the balustrade assembly varies the position of the skirt panel relative to moving steps in two directions by pushing against stationary components that are a part of or otherwise connected to a frame of a passenger conveyor. A balustrade support employed in the assembly reduces material and manufacturing costs and is adjustable to vary the height of a balustrade panel and handrails in a passenger conveyor.

  • Publication number: 20060191771
    Abstract: A display device (40) for use with a passenger conveyor (20) provides a traffic flow direction indicator and visible maintenance information. One example includes a display panel (42) supported on a surface (38) that is conveniently positioned between a handrail (28) and a landing (24). In one example, a single display panel (42) alternatively provides the traffic flow direction indicator or the maintenance information. In another example a first display panel (42) and a second display panel (48) are supported on a plate (43) that is selectively moveable into different positions, depending on which display panel should be visible. One example includes a remote signaling device (62) that allows an individual to control the information shown on the display device (40).
