摘要:
A passenger conveyor (20) includes a handrail assembly (30) comprising a handrail (32) having a plurality of co-extruded polymer materials (34, 36). In one example, an outermost portion (34) establishes a passenger gripping surface (38). One example includes an extruded soft, low cost polymer in the middle of the handrail cross section to reduce cost and weight. A disclosed example includes a toothed driving surface (40) on an inner side made of a selected one of the polymer materials (34, 36). In one example, the driving surface (40) and the gripping surface (38) comprise the same polymer material.

摘要:
A passenger conveyor handrail (30) includes a plurality of teeth (36) that interact with a toothed driving member (42). In a disclosed example, a low friction material (60) is placed near an end of the teeth (36) on the handrail (30). The low friction material (60) facilitates the teeth sliding along a guidance (70) but does not interfere with a desired engagement between the teeth(36) and corresponding teeth (46) on the driving member (42).

摘要:
A passenger conveyor handrail (30) is driven by a device (40) including a toothed drive belt (42). An example drive belt has a plurality of teeth (46) with an at least partially concave surface (50) for engaging teeth (36) on the handrail (30). A disclosed example also includes at least partially convex projections (52) near an end of each tooth on the drive belt (42). A driven surface (48) of the drive belt (42) includes a plurality of grooves (70) arranged to allow the drive belt to slip relative to a drive wheel (60) under certain loading conditions. The disclosed example arrangement facilitates proper engagement between a drive belt (42) and a toothed handrail (30) while avoiding vertical separation forces between them, which allows for eliminating pinching rollers that would otherwise engage a gripping surface (32) on the handrail (30).
摘要:
A passenger conveyor includes an endless tread band having a plurality of treads. At least one endless drive chain is driven around a first and a second turn around section by a drive. The drivetrain includes a plurality of links that are associated with drive chain rollers. A plurality of the treads are connected with the drivetrain. At least one panel member is located on a lateral side of the treads. The panel member is moveable with respect to the treads and supported to remain stationary with respect to at least one of the drive chain links. Each of the treads is associated with at least one panel member.
