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 handrail (30) has a gripping surface (32, 42, 52, 62, 72, 82) with a generally circular cross-section. Disclosed examples include a toothed driven surface (34, 44, 54, 64, 74, 84) that is adapted to be engaged by a toothed driving member (28) for propelling the handrail in a desired direction. Disclosed examples include having the generally circular cross-section extend along an entire length of the handrail (30) corresponding to the closed loop path followed by the handrail during operation of a corresponding passenger conveyor.

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 sliding layer (40) that is non-woven in some examples and non-fabric in other examples. A first polymer material is used to establish a body portion (32) of the handrail (30) to provide, for example, a gripping surface (34). The sliding layer (40) is secured to a surface (38) of the handrail (30) to cover at least a portion of that surface to meet the needs of a particular situation. Disclosed examples include a variety of configurations and a variety of techniques for applying such a sliding layer (40) to a handrail (30).

摘要:
A passenger conveyor system (20) includes a handrail assembly (30) having a guidance (40) for guiding a moving handrail (32). The example guidance includes an extrusion and presents a continuous, uninterrupted guiding surface (44) along which the handrail (32) travels. In a disclosed example, a single-piece extrusion (50) extends along an entire length of a balustrade (34). A disclosed example includes a first material forming a body of the guidance (40) and a second material (70) establishing the guiding surface (44).
