Patent ID: 8235331

Claim:
An apparatus, said apparatus comprising: a. a flexible duct, said flexible duct being circular in cross section, said flexible duct defining a duct horizontal portion and a duct curved portion, said duct horizontal portion being straight, said duct curved portion defining a substantially 90 degree bend, said substantially 90 degree bend defining a direction, said duct having a duct bottom surface, said duct bottom surface defining a duct bottom surface radius of curvature in said direction of said substantially 90 degree bend; b. a duct support, said duct support having a longitudinal axis and defining a duct supporting surface, said duct supporting surface being arcuate and normal to said longitudinal axis, said duct supporting surface defining a supporting surface horizontal portion, said supporting surface horizontal portion engaging and supporting said duct horizontal portion; c. said duct supporting surface defining a supporting surface curved portion, said supporting surface curved portion having a supporting surface radius of curvature equal to said duct bottom surface radius of curvature in said direction of said substantially 90 degree bend, said supporting surface curved portion engaging said duct bottom surface of said duct curved portion at said substantially 90 degree bend; d. said duct support defining a first slot and a second slot communicating through said duct supporting surface, said first slot and said second slot defining a bar between said first and second slots, each of said slots being configured to receive a strap, said strap communicating through said first slot and said second slot, said bar being configured to prevent disengagement of said strap from said duct support, said strap having a first distal end and a second distal end, said first distal end and said second distal end being secured to a structural member.
