Patent number: 7571797Abstract: The present invention provides a newel guide for supporting a handrail, comprising: a friction belt having a closed curved shape and including an outer surface in contact with an internal surface of the handrail; and a support member for supporting an inner surface of the friction belt to allow the friction belt to make an endless continuous movement around the support member. The support member includes a newel frame having a pair of plate members at its upper portion, wherein the plate members are separated from each other and extend in a longitudinal direction of the newel frame. An intermediate guide is mounted on the pair of plate members and has a depressed surface in contact with the inner surface of the friction belt. A pair of joint guides is mounted to the newel frame adjacent to both ends of the intermediate guide, wherein an end of the joint guide provides a support surface for supporting the endless continuous movement of the friction belt.Type: GrantFiled: January 13, 2005Date of Patent: August 11, 2009Assignee: Otis Elevator CompanyInventor: Jin Koo Lee

Patent number: 7562759Abstract: 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).Type: GrantFiled: August 22, 2005Date of Patent: July 21, 2009Assignee: Otis Elevator CompanyInventors: Changsheng Guo, Klaus Seehausen, Bernward Engelke, Detlev Lindemeier, John M.

Publication number: 20090127067Abstract: 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).Type: ApplicationFiled: April 24, 2006Publication date: May 21, 2009Inventors: Changsheng Guo, John M.

Publication number: 20090071798Abstract: The invention relates to a hand rail for an escalator or a moving walkway, comprising a flexible base body (1) with two lateral lips (2a, 2b) that wrap around a guide rail (4). The respective ends of the lateral lips are provided with a bulge (6a, 6b), which engages in a corresponding guide groove (8a, 8b) of the guide rail (4), thus securing the hand rail against lateral slippage. The invention also relates to a corresponding guide rail (4), which is equipped with a guide groove (8a, 8b) for guiding the lateral lips of the hand rail.Type: ApplicationFiled: August 30, 2005Publication date: March 19, 2009Applicant: SEMPERIT AG HOLDINGInventors: Albrecht Dürrer, Herwig Miessbacher

Publication number: 20090008217Abstract: 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).Type: ApplicationFiled: August 12, 2005Publication date: January 8, 2009Applicant: OTIS ELEVATOR COMPANYInventors: Changsheng Guo, John M.
