Abstract
Official abstract text for this publication.
Pliable-wall air ducts with internal expanding structures are disclosed. An example air duct system includes an air duct including a pliable sidewall. The example air duct system further includes a shaft including a first end and a second end. The shaft extends in a longitudinal direction along a length of the air duct with the first end coupled to a first point of the air duct and the second end coupled to a second point of the air duct. The first point is downstream of the second point. The pliable sidewall is to be held in tension in the longitudinal direction between the first and second points in response to compression in the shaft between the first and second ends.
First claim
Opening claim text (preview).
What is claimed is: 1. An air duct system comprising: an air duct including a pliable sidewall; and a shaft including a first end and a second end, the shaft extending in a longitudinal direction along a length of the air duct with the first end coupled to a first point of the air duct and the second end coupled to a second point of the air duct, the first point being downstream of the second point, the pliable sidewall to be held in tension in the longitudinal direction between the first and second points in response to compression in the shaft between the first and second points. 2. The air duct system of claim 1 , further including: a rib within the air duct; and a retainer to hold the rib substantially fixed relative to the pliable sidewall at the first point of the air duct, the first end of the shaft coupled to the air duct via at least one of the rib or the retainer. 3. The air duct system of claim 2 , wherein the retainer is on an exterior of the pliable sidewall. 4. The air duct system of claim 2 , wherein the retainer is within an interior of the pliable sidewall. 5. The air duct system of claim 1 , further including: a first rib within the air duct adjacent the first end of the shaft; and a second rib within the air duct and spaced apart from the first rib, the second rib adjacent the second end of the shaft, the first and second ribs to hold the air duct in a radially expanded shape. 6. The air duct system of claim 5 , wherein the shaft is coupled to the air duct via the first and second ribs. 7. The air duct system of claim 5 , further including a third rib within the air duct between the first and second ribs. 8. The air duct system of claim 1 , wherein the shaft is within the air duct.
