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. Stephan, Kevin J. Gebke, Michael A. Jacobson, Nicholas L. Kaufmann, William A. Niehaus

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. Gebke, Frank Heim, Michael A. Jacobson, Nicolas B. Paschke, Cary Pinkalla

Publication number: 20160356523Abstract: 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: ApplicationFiled: August 22, 2016Publication date: December 8, 2016Inventors: Cary Pinkalla, Jeff Logic, Kevin J.

Patent number: 8844578Abstract: 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: GrantFiled: November 19, 2010Date of Patent: September 30, 2014Assignee: Rite-Hite Holding CorporationInventors: Cary Pinkalla, Frank Heim, Kevin J. Gebke, Nicholas L. Kaufmann, William A. Niehaus

Patent number: 8676545Abstract: Example methods, apparatus, and articles of manufacture to determine pliable air duct configurations are disclosed. A disclosed example method involves determining a first quantity of adjustable air outlet duct sections to configure an air delivery duct system when an operating mode identifier is received. The operating mode identifier is associated with an amount of air delivered by the air delivery duct system into targeted areas. The first quantity of adjustable air outlet duct sections is based on an airflow rate value and the operating mode identifier. The airflow rate value is indicative of airflow through an air delivery duct system. Each adjustable air outlet duct section includes at least one adjustable air outlet having at least one size-adjustable orifice.Type: GrantFiled: July 7, 2010Date of Patent: March 18, 2014Assignee: Rite-Hite Holding CorporationInventors: Nicholas L.

Publication number: 20080176506Abstract: An air diffuser includes a porous fabric panel having areas of different flow coefficients. The areas' positions and their relative flow coefficients provide a means for not only diffusing the air but also for strategically directing the airflow in a deliberate pattern that promotes intermixing of the air while avoiding adverse air currents. Consequently, the porous fabric itself provides air dispersion and airflow direction without the need for louvers or guide vanes. In some embodiments, the fabric's porosity is programmed by laser cutting small slits into the fabric.Type: ApplicationFiled: January 22, 2007Publication date: July 24, 2008Applicant: RITE-HITE HOLDING CORPORATIONInventors: Kevin J.

Patent number: 5542463Abstract: A roll-up strip curtain barrier apparatus is provided which provides a curtain member suspended from a support roller rotatably mounted about a door opening. The curtain member has plurality of flexible curtain-like strip panels which are adapted to span the door opening and provide an air-blocking seal. In one embodiment, the plurality of the strip panels are disposed in a plurality of rows, each row having a plurality of adjacent strip panels. The panels in one row are in abutting and overlapping relationship with the panels in the adjacent row. In one mode of operation, the flexible strip panels deflect in response to personnel and material passing through the door opening and then return to their original suspended position. In another mode of operation, the support roller may be rotated so as to wind and elevate the curtain member about the roller and create an unobstructed door opening. Reverse rotation of the support roller lowers the curtain member to the sealing position.Type: GrantFiled: July 15, 1994Date of Patent: August 6, 1996Assignee: Rite-Hite CorporationInventors: Cary Pinkalla, Garrett Goins
