A passenger conveyor includes a first stationary structure and a second stationary structure; a step positioned between the first stationary structure and the second stationary structure, the step has a tread with a tread surface; and a skirt secured to the step between the step and the first stationary structure, the skirt includes an upper tread edge; wherein the upper tread edge extends beyond the tread surface by at least about 10 mm.

Skirt for passenger conveyer

A passenger conveyor includes an endless tread band having a plurality of treads. At least one endless drive chain is driven around a first and a second turn around section by a drive. The drivetrain includes a plurality of links that are associated with drive chain rollers. A plurality of the treads are connected with the drivetrain. At least one panel member is located on a lateral side of the treads. The panel member is moveable with respect to the treads and supported to remain stationary with respect to at least one of the drive chain links. Each of the treads is associated with at least one panel member.

A display device () for use with a passenger conveyor () provides a traffic flow direction indicator and visible maintenance information. One example includes a display panel () supported on a surface () that is conveniently positioned between a handrail () and a landing (). In one example, a single display panel () alternatively provides the traffic flow direction indicator or the maintenance information. In another example a first display panel () and a second display panel () are supported on a plate () that is selectively moveable into different positions, depending on which display panel should be visible. One example includes a remote signaling device () that allows an individual to control the information shown on the display device ().

People conveyor () having an endless people transportation band () and an endless handrail (), a glass balustrade () arranged laterally to the transportation band () and supporting the handrail (), and a profile () having an U-shaped channel () for engaging the glass balustrade () and comprising an illumination cavity (), wherein a plurality of LEDs is arranged in the illumination cavity ().

A balustrade fastening arrangement for an escalator or passenger conveyor having a moveable skirt panel whereby the fastening arrangement secures an inner decking panel such that it overhangs the moving skirt panel between the skirt panel and the step.

Balustrade fastening arrangement

People mover () comprising an endless tread belt () formed from several tread elements () connected to one another, which is driven by a drive unit about a first and second reversal point (), and a side skirt () moved along with tread belt (), the side skirt () comprising flange elements () joined to the tread element () and bridge elements () connected movably relative to flange elements (). A sensor () is arranged adjacent to the side skirt (), the sensor () having a limited detection range perpendicular to the circulation direction of side skirt (), and a plurality of marking elements are arranged in a line on side skirt () along the circulating direction having a limited width perpendicular to the circulating direction.

Safety monitoring system for a people conveyor

A passenger conveyor handrail () includes a plurality of teeth () that interact with a toothed driving member (). In a disclosed example, a low friction material () is placed near an end of the teeth () on the handrail (). The low friction material () facilitates the teeth sliding along a guidance () but does not interfere with a desired engagement between the teeth() and corresponding teeth () on the driving member ().

A display device () for use with a passenger conveyor () provides traffic flow direction information. One example includes a display panel () supported on a surface () that is conveniently positioned beneath the handrail () near a landing (). In a particular example, a handrail entry module () includes a handrail entry () and a support surface () that supports the display (). In one example, the surface () extends down and out from a vertical surface () associated with the handrail entry () to maximize visibility of the display.

An escalator drive assembly includes a backup member () that facilitates controlling movement of the escalator () even when the normal drive assembly operation is interrupted. A backup member () in the form of a flange () is associated with a drive pulley () and normally rotates in unison with the drive pulley (). When there is a failure in the normal operation of the drive mechanism, however, there is a resulting relative movement between the backup member () and the drive pulley (). Such relative motion preferably activates a switch () that provides a signal that indicates a failure of the normal operation of the drive mechanism. The backup member () facilitates providing an indication of a failure and control over movement of the escalator () even when the normal drive assembly is not operating as intended.

A pallet for a passenger conveyor includes an integrally formed thin walled support frame. The support frame walls all extend in the same principle direction to permit the support flame to be formed by an extrusion process. In a particular embodiment, the support frame includes thin walls extending in the width dimension. In another embodiment, the support frame includes multiple, integrally formed pieces having thin walls extending in the length dimension. The width of the support frame is dependent on the combined width of the multiple pieces.

A newel guide for supporting a passenger conveyor handrail traveling over a newel includes an integral one piece body and a plurality of rollers. The one piece body may be formed by an extrusion process and formed into the desired shape. In a particular embodiment, the one piece body incorporates an attachment portion, a deflector portion and a portion to retain the rollers. A transition piece is used between the newel guide and the handrail guide to smoothly transition between the guides. The transition piece has a profile to match the newel guide on one end and a profile to match the handrail guide on the opposite end.

Newel guide for a handrail

A pallet for a conveyor includes a first connector, a second connector, and a link engaging the connectors of adjacent pallets. The link permits the connectors of adjacent pallets to move relative to each other through an arcuate path. This arrangement for adjacent pallets results in a connection between the pallets that accommodates the varying distance between the adjacent pallets as they travel through a curved path.
