Abstract
Abstract An air turning assembly and bracket for holding readily compressible fibrous air turning vanes within an air conduit. The assembly is characterized by a compression bracket for holding the fibrous vanes in position between supporting parallel rails, and connection between the vane and brackets being such as to minimize wind resistance and prevent the transmission of vibration and noise to the duct assembly.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
110 words
In an air turning assembly comprising parallel spaced vane support rails with a plurality of fibrous vane members mounted between said rails, mounting means for said vanes comprising a metallic bracket member having spaced parallel leg portions and a back portion, an aperture in each said leg portion, the apertures of said legs being in registry with each other, said leg portions being positioned with respect to a vane to include a mass of vane material between said legs, connector means extending through said apertures and said included mass of said vane for compressing said mass between said legs, and fastener means for securing said back portion to said rail.
Claim 2
Dependent Claim
110 words
In an air turning assembly comprising parallel spaced vane support rails with a plurality of fibrous vane members mounted between said rails, mounting means for said vanes comprising a metallic bracket member having spaced parallel leg portions and a back portion, an aperture in each said leg portion, the apertures of said legs being in registry with each other, said leg portions being positioned with respect to a vane to include a mass of vane material between said legs, connector means extending through said apertures and said included mass of said vane for compressing said mass between said legs, and fastener means for securing said back portion to said rail.
Claim 3
Dependent Claim
48 words
The device of claim 1 wherein said back portion and said rail include complemental locator seats and tabs, said seats and tabs being in registry in the mounted position of said bracket on said rail and preventing relative movement of said parts in the plane of said rail.
Claim 4
Dependent Claim
17 words
The device of claim 2 wherein said seats and extensions are laterally offset from said fastener means.
Claim 5
Dependent Claim
33 words
The device of claim 1 wherein one of said legs includes a sharpened point portion at its distal end, said one leg and point being inserted into the mass of said vane material.
Claim 6
Dependent Claim
52 words
The device of claim 4 wherein said connector means comprises a blind rivet, the formed end of said rivet being disposed adjacent the aperture in said one leg and concealed within the mass of said vane, the headed end of said rivet being engaged against said other leg of said bracket member.
Claim 7
Dependent Claim
106 words
An air turning assembly comprising a pair of spaced parallel vane support rails, a plurality of readily deformable, compressible, fibrous air turning vanes mounted between said rails, said vanes having a mounted bracket connected to each end, the brackets of each vane being fixed to a different rail, said brackets each including a pair of legs embracing a mass of said fibrous material, an aperture in each said leg, said apertures being coaxially located, and a compression fastener member spanning said legs and clamping and compressing said mass of material therebetween, thereby to indent said legs with respect to the air flow surfaces of said vanes.
Claim 8
Dependent Claim
106 words
An air turning assembly comprising a pair of spaced parallel vane support rails, a plurality of readily deformable, compressible, fibrous air turning vanes mounted between said rails, said vanes having a mounted bracket connected to each end, the brackets of each vane being fixed to a different rail, said brackets each including a pair of legs embracing a mass of said fibrous material, an aperture in each said leg, said apertures being coaxially located, and a compression fastener member spanning said legs and clamping and compressing said mass of material therebetween, thereby to indent said legs with respect to the air flow surfaces of said vanes.
Claim 9
Dependent Claim
18 words
An air turning assembly in accordance with claim 6 wherein said compression fastener member comprises a blind rivet.
Claim 10
Dependent Claim
31 words
An air turning assembly in accordance with claim 6 wherein said brackets and said rails include interfitting slot and tab means for locking said brackets against movement relative to said rails.
Claim 11
Dependent Claim
69 words
An air turn device in accordance with claim 6 wherein one of said legs includes a sharpened point portion, said one leg being inserted into the mass of said vane, said fastener means comprising a blind rivet having a formed end engaged against said one leg and a headed end engaged against the other leg of said bracket, said formed end being concealed within the mass of said vane.
