Abstract: The outer and inner side decks of a curved escalator are connected at its inner end to the balustrade, and includes a horizontal top panel which extends outwardly away from the balustrade, and outer vertical curved in plan side panel which extends downwardly from the outer edge of the top panel. These deck panels are secured to inner support components of the deck. The corner of the deck where the top and side panels meet is covered with a plastic trim molding which covers the screws fastening the side panel to the underlying supports, and which snaps onto catches which are hidden on the underside of the top panel. An attractive corner is thus formed free of unsightly screws, bolts, or other fasteners.

Abstract: The curved escalator has inner and outer step chains that are entrained on inner and outer sprockets which have different diameters, the outer sprocket having a larger diameter than the inner sprocket. The steps of the escalator reverse their direction of movement at the sprockets and pass from the passenger bearing run to a return run beneath the passenger bearing run. One of the sprocket sets is the power or driving set and the other is an idler set, which will be spring biased to maintain chain tension. In order to reverse the steps, they must tip or dip sideways because of the different sized sprockets. The dip zone of the roller tracks has an S curve to minimize noise and allow location of the track splice on the tensioned end of the escalator to be placed over the axis of rotation of the tensioned sprockets.

Abstract: The guide rail for an escalator handrail is provided with a plurality of laterally extending pins which provide the sole contact with the handrail. The pins reduce frictional drag of the handrail by providing line and point contact only between the handrail and the guide rail.

Abstract: The handrail drive is a mangle-type drive wherein the handrail passes through the nip of a pair of opposed drive rollers. A plurality of drive roller pairs may be used. The drive rollers are keyed to rotatable shafts to which drive sprockets are also keyed. The drive sprockets are rotated by an endless chain which in turn is driven by one or more powered sprockets. The drive roller shafts are journaled in rotatable bearings which are mounted in a mechanism housing with the bearings being eccentrically mounted in the housing with respect to the drive roller shafts. When the drive rollers are rotated, friction between the handrail and the drive rollers, and between the roller shafts and eccentric bearings will cause the bearings to rotate about their axes thereby tightening the drive rollers about the handrail. As handrail drive roller friction increases, the tightening effect also increases. The rollers will only tighten on the extent needed to overcome the friction between the handrail and its guide rail. When the drive mechanism is turned off, the drive rollers only lightly engage the handrail.

Abstract: An escalator is provided with a curved path of travel from its entry to its exit landings. The path of travel of the escalator steps as seen in plan is a curve having a fixed center and a constant radius from landing to landing. In elevation, each landing portion will be disposed in vertically spaced horizontal planes, and there will be a medial constant slope ascending or descending portion. Interconnecting each landing portion with the constant slope portion will be entry and exit transitional curved portions of varying slope as seen in the elevational view. To enable the steps to traverse the curved path successfully, the effective length of the outer of the step chains is varied at different points along the path of travel of the escalator.
