  • Patent number: 5566810
    Abstract: Movement of the handrail on an escalator or moving walkway passenger conveyor is smoothed out by providing a totally elastomeric coupling between the conveyor step chain and the handrail drive mechanism. The handrail drive mechanism is a friction drive roller, or belt, which is driven by being connected to the step chain. The connection between the step chain and the handrail drive is provided by an elastomeric member which engages both a step chain-driven sprocket and the handrail drive mechanism. The elastomeric connection damps out jerks which are created by the chordal nature of the step chain and the main motor drive chain as the chains pass around chain return sprockets. The elastomeric connection therefore smooths out movement of the handrail.

  • Patent number: 5131521
    Abstract: A moving handrail on an escalator or the like is driven by pairs of rollers which form a nip through which the handrail moves. The rollers are eccentrically mounted so as to automatically tighten the nip in response to resistance to movement of the handrail. The roller or rollers which contact the underside of the handrail are rotatably driven by power sprockets, while the roller or rollers contacting the outer or exposed surface of the handrail are idler rollers which are not rotated by the power sprockets so as to lessen scuffing of the exposed surface of the handrail by the rollers.

  • Patent number: 5131520
    Abstract: The escalator handrail guide rail assembly includes a metal base which can be snap fitted onto a glass escalator or walkway balustrade. A low friction plastic strip is fitted onto the top of the base for contact with the handrail, and a metal reinforcing piece is snap fitted onto the base over the plastic strip to hold the latter in place, and to reinforce the plastic strip. The reinforcing piece is formed from two identical interleaved strips which can be attached to and detached from the base without the use of any tools more specialized than a rubber mallet and without the use of separate fasteners such as screws, bolts, or the like.

  • Patent number: 5117960
    Abstract: An escalator or moving walkway handrail is driven by a pair of linear belts which engage opposite sides of the handrail along the return path of travel thereof. The belt that engages the underside of the handrail is a powered drive belt, and the belt that engages the upper-side of the handrail is a pressure or reaction belt. Both belts are held against the handrail by a set of biased pressure rollers which urge the reaction belt against the handrail. The belts serve to convert line contact with the pressure rollers into area contact with the handrail thereby spreading out the driving forces acting upon the handrail.

  • Patent number: 5115900
    Abstract: An air supporting system is provided for a handrail of a passenger conveyor and includes a plenum. An air supply provides air flow to the plenum. A guide is mounted on one side thereof to the plenum. The guide includes at least one air pocket. A handrail is slidably engaged with the guide. An orifice through the guide allows air to pass from the enclosed space to the air pocket. The air in the pocket generates pressure and lift to the handrail as it is driven to decrease friction between the handrail and the guide and to support the handrail above the guide.

  • Patent number: 5029690
    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.

  • Patent number: 5018616
    Abstract: The handrail drive utilizes one or more pairs of drive rollers which form a nip through which the handrail moves. The drive rollers are mounted on rotating drive shafts which in turn are eccentrically mounted in rotatable bearings. The drive rollers will automatically tighten on the handrail as friction increases between the rollers and handrail due to increased resistance to movement of the handrail. The rotatable bearings are connected together to ensure that each roller tightens equally on each side of the handrail so that the handrail is not bent through an S curve as it passes through the drive roller nip.

  • Patent number: 4998613
    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. The housing is divided into two halves, each mounting one of the rollers in a drive roller pair. The two housing halves are hinged together so that the nip of each drive roller pair can be opened by pivoting one half of the housing away from the other half of the housing.

  • Patent number: 4984671
    Abstract: The balustrade of a linear or curved escalator has upper and lower edges that are curved in elevation between the horizontal landing portions and the constant slope inclined medial portion of the escalator. The radius which defines the upper and lower balustrade curves is developed so as to have the maximum value possible without producing a discontinuity in the vertical distance between the escalator handrail and the escalator tread surface which would be noticeable by a passenger on the escalator.

  • Patent number: 4953686
    Abstract: The balustrade for transportation apparatus, such as an escalator or a moving passenger walkway contains upright balustrade panels directly laterally guiding tread elements, such as steps or tread plates so as to dispense with both of the conventionally employed inner balustrade decks with their associated inner deck covers. A respective stable support profile member connected with a support body and arranged at both sides of a transport element, such as a step or tread plate band receives the base of the associated balustrade panel. The heads of screws or threaded bolts required for fastening the associated balustrade panel are arranged counter-sunk in openings of such balustrade panel. Apart from the savings in cost realized with the invention it is also possible to reduce the entire structural width of the transportation apparatus.
