  • Modular chain newel with standard bearing
    Patent number: 8931615
    Abstract: A roller bearing and newel guide assembly (30) for a newel (24) in an escalator (10) has a newel guide (32), a roller chain (34), and a spring (40) connected between the roller chain (34) and the newel guide (32) to provide tension to the roller chain (34). The roller chain (34) comprises a series of interlinked chain units (36). Each chain unit (36) includes a frame (78), at least one roller bearing (72), and a pin (76) for connecting the roller bearing (72) to the frame (78). Each chain unit (36) has a female connector (62) and a male connector (64), which allow each chain unit (36) to connect to an adjacent chain unit (36) to form the roller chain (34).

  • Balustrade and deck mounting assembly for a passenger conveyor
    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.
