SUPPORT STRUCTURE FOR VACUUM DUCT |
摘要 |
A folding structure supports a duct in a generally horizontal orientation, and permits speeping and serpentine movement of the duct. The structure is foldable for storage and transport. The structure comprises an array of panels hinged together, with the structure featuring a gentle upward curve from its base to its free end for counteracting the weight of the loaded duct.
