Publication number: 20170159966Abstract: Pliable-wall air ducts with internal expanding structures are disclosed. An example air duct system includes a shaft to be disposed within an air duct, to extend in a longitudinal direction, and to be in longitudinal compression. The air duct system also includes a plurality of ribs to be coupled to the shaft and to engage an inner surface of the air duct and a spring to be disposed within the air duct, the spring to be coupled to the shaft. The spring under stress being a contributing factor in both the shaft being in longitudinal compression and the air duct being in longitudinal tension.Type: ApplicationFiled: February 16, 2017Publication date: June 8, 2017Inventors: Cary Pinkalla, Frank Heim, Kevin J.

Publication number: 20170159965Abstract: Example air ducts comprising pliable tubular sidewalls are provided with example internal frameworks that hold the duct in a generally expanded shape even when the duct is depressurized. The framework tensions the pliable sidewall material along the length of the ducts to keep the material taut. In some examples, the framework is restrained within the duct such that the duct's sidewall, being in tension, holds the framework in compression longitudinally. Thus, in the longitudinal direction, the duct is in tension and the framework is in compression. To prevent the framework from buckling under the compressive force, some example frameworks comprise a central longitudinal shaft with a plurality of radial spokes and rings that help hold the shaft straight. In some examples, the rings also help hold the duct radially expanded.Type: ApplicationFiled: February 16, 2017Publication date: June 8, 2017Inventors: Cary Pinkalla, Frank Heim, Kevin J. Gebke, Nicholas L. Kaufmann, William A. Niehaus

Patent number: 9644858Abstract: Example air duct assemblies include a pliable air duct supported such that the duct is maintained in a generally expanded shape even when the duct is deflated. In some examples, a series of hangers suspend the duct from one or more cables, tracks or other type of overhead support. The hangers are spaced apart and distributed over the length of the duct, and each one contributes in pulling the duct taut in the duct's longitudinal direction.Type: GrantFiled: May 29, 2014Date of Patent: May 9, 2017Assignee: RITE-HITE HOLDING CORPORATIONInventors: Cary Pinkalla, Jeff Logic, Kevin J.

Publication number: 20170003049Abstract: In some example pliable air duct systems, inflatable ducts of various diameters and lengths are created by selectively assembling pre-existing stock pieces in different combinations. In some examples, the stock pieces include disconnectable longitudinal joints and disconnectable circumferential joints, wherein the longitudinal joints enable interconnecting multiple stock pieces to achieve a desired tube diameter, and the circumferential joints allow connecting multiple tube segments end-to-end to produce an air duct assembly of a desired length. To control the volume and/or the direction of air discharged from the duct, the duct assembly, in some examples, includes an adjustable register comprising a movable pliable sheet that overlies a discharge opening in a pliable sidewall of the duct. In some examples, the inflatable duct includes one or more cutout patterns on the duct's sidewall to provide guidance in creating a sidewall discharge opening of a proper size and location.Type: ApplicationFiled: September 16, 2016Publication date: January 5, 2017Inventors: Cary Pinkalla, Frank Heim, Irene E.

Patent number: 9518756Abstract: An external suspension system for supporting an inflatable air duct includes a series of external hangers that help hold the duct open while the duct is deflated. In some embodiments, the suspension system supports the duct at a series of points that are broadly distributed in a staggered pattern across the duct, yet the entire duct can be suspended from a single overhead cable, even if the duct is a stepped tube with multiple diameters. The system includes novel ways of locking the hangers to the duct and to the overhead cable.Type: GrantFiled: November 15, 2006Date of Patent: December 13, 2016Assignee: RITE-HITE HOLDING CORPORATIONInventors: Robert Brown, Kevin J.

Patent number: 9039503Abstract: An air duct assembly includes upper and lower pliable sheets that can be assembled in a sequence that makes the assembly easier to install and later easier to remove for periodic cleaning. To install the assembly, the upper sheet can be installed first by inserting the edges of the upper sheet within a pair of tracks and then fastening the upper sheet to a vertical supply air duct. An optional airflow modifier (e.g., filter, airflow turning vane, or noise attenuator) can be install where the supply air duct connects to the upper sheet. Once the upper sheet is suspended from the tracks and fastened to the main supply air duct, the lower sheet can be installed separately. Pliable end panels and pliable fasteners (e.g., zipper or VELCRO fastener) can make most of the air duct assembly machine washable. The upper and lower sheets can have different degrees of air permeability.Type: GrantFiled: February 29, 2008Date of Patent: May 26, 2015Assignee: RITE-HITE HOLDING CORPORATIONInventors: Kevin J.
