Abstract: A tray is mounted along a telescoping structure, typically suspended beneath a segment of the telescoping structure. The tray provides a space for a flexible conduit to be gathered into and payed out from as the structure changes in length. A conduit connector couples segments of the conduit and defines a fluid path which makes two substantially right angle turns to increase the minimum radius which the flexible conduit must assume during the expansion and contraction of the structure. The flexible conduit can be attached to rigid conduits extending between the tray and either end of the structure. A Z-shaped conduit connector can be pivotally mounted to the tray, or can be articulated, to increase the usable length of flexible hose stored within the tray.

Abstract: A telescoping conduit for directing air at moderate pressures to a waiting aircraft along a telescoping bridge is disclosed. One telescoping tube is suspended from each segment of the telescoping bridge. The tubes are coaxially supported from the bridge by adjustable brackets. A tube at one end of the bridge is suspended from its bridge segment at both ends of the tube, while the remainder of the tubes are suspended from a single end. This allows the tubes to fully telescopically extend and retract while providing support for the tubes at each end. A sealing portion at one end of the tubes is somewhat flexible to accommodate slight misalignment of the tubes. Also disclosed is a roller cage for centering the nesting tubes so that a wiper seal between the nesting tubes is not damaged.
