    摘要： A drive pulley system is provided for a handrail drive mechanism (30) of a passenger conveyor (10). The system includes a pulley (46), with a handrail drive belt (32) wrapped about the pulley (46) for rotation therewith. A pair of disc-like members (58) are disposed on opposite sides of the pulley (46) to sandwich the pulley (46) therebetween. The disc-like members (58) have diameters greater than that of the pulley (46) and are rotatable relative to the pulley (46), or the disc-like members (58) may be fixed to the pulley (46) and be fabricated of low friction material. The handrail (20) is wrapped about the outer peripheries of the disc-like members (58), spacing the handrail (20) from the drive belt (32), and thereby allowing differential linear movement between the handrail drive belt (32) and the handrail (20) due to the relative rotation between the disc-like members (58) and the pulley (46), or due to slippage between the handrail (20) and the low friction disc-like members (58). The system also includes an idler pulley (44) disposed in an area between the pulley (46) and a second pulley (42) and about which both the handrail drive belt (32) and the handrail drive are wrapped to impart drive to the handrail (20) by the drive belt (32). The idler pulley (44) substantially spans the area between the other two pulleys (42, 46) to provide a large included angle (54) of engagement between the idler pulley (44), the handrail (20) and the handrail drive belt (32).

    摘要： An air supporting system is provided for a handrail (18) of a passenger conveyor (10) and includes a plenum (30). An air supply (34) provides air flow to the plenum (30). A guide (24) is mounted on one side thereof to the plenum (30). The guide (24) includes at least one air pocket (36). A handrail (18) is slidably engaged with the guide (24). An orifice (38) through the guide (24) allows air to pass from the enclosed space to the air pocket (36). The air in the pocket (36) generates pressure and lift to the handrail (18) as it is driven to decrease friction between the handrail (18) and the guide (24) and to support the handrail (18) above the guide (24).
