Abstract
Abstract A mounting structure means for mounting air-directing means within an air plenum chamber duct assembly of folded ductboard, mounted upon an air diffuser assembly, comprising a support body of preformed sheet metal formed in the general shape of the interior of the duct to be held in fixed relation therein by the interengagement of corresponding surfaces. The body has flanges which extend under clips or into slitlike openings in the duct to aid in maintaining the body in position. The body mounts an air inlet collar and/or air vanes of either channel or angle cross section to direct the air from the inlet to the outlet of the plenum chamber duct assembly and through the air diffuser assembly.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
85 words
A mounting structure means as part of an air distribution system for mounting air-directing means to an air plenum chamber duct of folded insulation board mounted upon an air diffuser assembly, said plenum duct having an air inlet and an air outlet to said diffuser assembly, said structure comprising: a support body preformed out of a sheet of deformable material and positioned within said duct, said body being held in generally fixed relation therein through engagement with three or more surfaces of said folded duct.
Claim 2
Dependent Claim
85 words
A mounting structure means as part of an air distribution system for mounting air-directing means to an air plenum chamber duct of folded insulation board mounted upon an air diffuser assembly, said plenum duct having an air inlet and an air outlet to said diffuser assembly, said structure comprising: a support body preformed out of a sheet of deformable material and positioned within said duct, said body being held in generally fixed relation therein through engagement with three or more surfaces of said folded duct.
Claim 3
Dependent Claim
37 words
A mounting structure means as in claim 1 wherein: said support body positioned within said duct is provided with at least one end flange, and clip means are provided for holding said end flange to said duct.
Claim 4
Dependent Claim
44 words
A mounting structure means as recited in claim 1 wherein: said support body positioned within said duct is provided with at least one end flange and the duct is provided with at least one slitlike opening, said flange being positioned with the slitlike opening.
Claim 5
Dependent Claim
24 words
A mounting structure means as recited in claim 3 wherein: said slitlike opening in the duct is formed by a fold of the ductboard.
Claim 6
Dependent Claim
52 words
The mounting structure means of claim 1 wherein said air-directing means comprises: an air inlet collar and said support body has mounting means associated therewith, including an opening therein, for mounting said inlet collar on said body with said collar projecting from within the plenum chamber duct outwardly through said air inlet.
Claim 7
Dependent Claim
43 words
The mounting structure means of claim 1 wherein said air-directing means comprises: air vane means for selectively changing the direction of the air distribution from said inlet toward said outlet and mounting means for mounting said air vane means to said support body.
Claim 8
Dependent Claim
96 words
The mounting structure means of claim 6 wherein: said air vane means comprises a pair of oppositely directed vanes of channellike cross section including side flanges and a planar web, said flanges having a width slightly greater than the normal distance between opposite inner surfaces of said duct and being interposed therebetween in an interference fiT, said mounting means for mounting said air vane means to said support body mounts said vanes to pivot between various positions within said duct; and said interference fit maintains said vanes in any selection position of adjustment within said duct.
Claim 9
Dependent Claim
77 words
The mounting structure means of claim 6 wherein: said air vane means comprises a multiplicity of angle vanes, said air-vane-mounting means for mounting said air vane means to said performed support body comprises pivotal mounting means pivotally mounting the vanes between opposite sides of the duct for movement between various positions and correlating means attached to each vane for obtaining a correspondence between the vane positions; and moving means for moving the vanes between various vane positions.
Claim 10
Dependent Claim
103 words
A mounting structure means as part of an air distribution system for mounting air-directing means within an air plenum chamber duct of folded insulation board mounted upon an air diffuser assembly, said plenum duct having an air inlet and air outlet to said diffuser assembly, said structure comprising a support body preformed out of a sheet of deformable material, said sheet having three or more generally planar surfaces, the generally planar surfaces of said body being in engagement with a like number of separate longitudinal generally planar surface on the duct to hold the body longitudinally in generally fixed relation with the duct.
Claim 11
Dependent Claim
103 words
A mounting structure means as part of an air distribution system for mounting air-directing means within an air plenum chamber duct of folded insulation board mounted upon an air diffuser assembly, said plenum duct having an air inlet and air outlet to said diffuser assembly, said structure comprising a support body preformed out of a sheet of deformable material, said sheet having three or more generally planar surfaces, the generally planar surfaces of said body being in engagement with a like number of separate longitudinal generally planar surface on the duct to hold the body longitudinally in generally fixed relation with the duct.
