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.

Patent number: 6997302Abstract: An escalator drive assembly includes a backup member (40) that facilitates controlling movement of the escalator (20) even when the normal drive assembly operation is interrupted. A backup member (40) in the form of a flange (42) is associated with a drive pulley (34) and normally rotates in unison with the drive pulley (34). When there is a failure in the normal operation of the drive mechanism, however, there is a resulting relative movement between the backup member (40) and the drive pulley (34). Such relative motion preferably activates a switch (80) that provides a signal that indicates a failure of the normal operation of the drive mechanism. The backup member (40) facilitates providing an indication of a failure and control over movement of the escalator (20) even when the normal drive assembly is not operating as intended.Type: GrantFiled: May 20, 2002Date of Patent: February 14, 2006Assignee: Otis Elevator CompanyInventors: Richard N. Fargo, Jorg Ostermeier, Charles Darling, Bernward Engelke, Ernst Führing, John Michael Milton-Benoit
