Abstract:
1. An air duct assembly for connection to a vertically extending inlet duct, the air duct assembly comprising: a pliable tube attached to the vertically extending inlet duct; an upper sheet comprising a first pliable material, the upper sheet defining an inlet opening with a first separable joint extending along a perimeter of the inlet opening for connecting the upper sheet to the pliable tube; a lower sheet comprising a second pliable material; the first separable joint connecting the upper sheet to the pliable tube to place the vertically extending inlet duct in fluid communication with the inlet opening of the upper sheet; a second separable joint coupling the upper sheet adjacent the lower sheet, the second separable joint, comprising: a third separable joint coupling the upper sheet adjacent the lower sheet, the second separable joint and the third separable joint being spaced-apart from each other with the upper sheet and the lower sheet extending therebetween, the second and third separable joints each connected with a support to position the upper sheet adjacent the supports generally laterally relative to the inlet duct, and the upper sheet, the lower sheet, and the separable joints defining an enclosed horizontally extending air passageway therebetween.
