Patent number: 8381895Abstract: A device (40, 50) for reducing noise levels in passenger conveyor systems (10) at least partially obstructs spacing (36) at the interface between two steps (24, 30) to allow for relative movement between one step and the next. A sound transmission reducing member (40, 50) at least partially obstructs a sound pathway that includes the spacing to reduce the transmission of noise through the spacing. The sound transmission reducing member in one example is a barrier that partially blocks the interface, while in another, it extends completely across the interface. Additionally, sound absorbing material (46) may be secured to the underside of the steps in order to further reduce sound transmission toward the passengers and individuals near the conveyer.Type: GrantFiled: February 17, 2004Date of Patent: February 26, 2013Assignee: Otis Elevator CompanyInventors: Carl Q. Howard, Andreas Stuffel, Larry W. Hardin, Goldino S. Alves

Patent number: 8016097Abstract: An escalator handrail drive arrangement includes a drive belt (26) mounted within a drive housing (35). Pressure rollers (30) are mounted in pairs and pivotally attached to the drive housing. The pressure rollers bias a handrail (22) against the drive belt. The pressure roller arrangements are mounted at each axial end. A spring (44) biases the pressure roller arrangements against the handrail, with the spring being centered along the axial length of the pressure rollers. This spring is preferably mounted within the drive housing such that no additional space is required outwardly of the drive and roller arrangement to accommodate the spring.Type: GrantFiled: February 6, 2003Date of Patent: September 13, 2011Assignee: Otis Elevator CompanyInventors: Andreas Stuffel, Helmut Meyer, Klaus Rohrbach
