Abstract
Abstract Wall means define a generally elongated, narrow air passage having an air discharge aperture extending substantially the full length of the elongated air passage and an air inlet located generally centrally of the elongated dimension of the air passage. A baffle or air deflecting means, disposed within the air passage opposite the mouth of the air inlet, is shaped so as to direct air entering the air passage in both directions along the elongated dimension of the air passage. Preferably the diffuser is equipped with adjustable shutter means mounted within the air passage and engageable with the air inlet so as to control the volume of air moving into the air passage from the air supply.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
252 words
An air diffuser comprising wall means defining an elongated air passage, said wall means including a first elongated side wall, a second elongated side wall, an elongated top wall, a first end wall and a second end wall, lowermost sections of said side walls defining an elongated air discharge aperture, said elongated air discharge aperture running substantially the full length of the elongated dimension of said air passage, said air passage between said side walls adjacent said air discharge aperture being less than the width of said air passage between said side walls adjacent said top wall, said air passage having an air inlet located in said first side wall generally centrally of the elongated dimension of said elongated air passage such that air supplied to said diffuser is fed directly into said air passage, baffle means disposed substantially wholly within said air passage, said baffle means being mounted on said second side wall and disposed generally opposite said air inlet, said baffle means having a shape such that at least a portion of the air entering said air passage and impinging on said baffle means is directed longitudinally towards respective ends of said air passage, adjustable, sliding shutter means mounted within said air passage, said shutter means being engageable with said air inlet whereby the volume of air entering said air passage may be controlled, air discharge pattern control means disposed in said air passage adjacent said air discharge aperture whereby air exiting through said air discharge aperture may be pre-directed.
Claim 2
Dependent Claim
252 words
An air diffuser comprising wall means defining an elongated air passage, said wall means including a first elongated side wall, a second elongated side wall, an elongated top wall, a first end wall and a second end wall, lowermost sections of said side walls defining an elongated air discharge aperture, said elongated air discharge aperture running substantially the full length of the elongated dimension of said air passage, said air passage between said side walls adjacent said air discharge aperture being less than the width of said air passage between said side walls adjacent said top wall, said air passage having an air inlet located in said first side wall generally centrally of the elongated dimension of said elongated air passage such that air supplied to said diffuser is fed directly into said air passage, baffle means disposed substantially wholly within said air passage, said baffle means being mounted on said second side wall and disposed generally opposite said air inlet, said baffle means having a shape such that at least a portion of the air entering said air passage and impinging on said baffle means is directed longitudinally towards respective ends of said air passage, adjustable, sliding shutter means mounted within said air passage, said shutter means being engageable with said air inlet whereby the volume of air entering said air passage may be controlled, air discharge pattern control means disposed in said air passage adjacent said air discharge aperture whereby air exiting through said air discharge aperture may be pre-directed.
Claim 3
Dependent Claim
40 words
The air diffuser of claim 1 wherein there are two adjustable shutter means, said shutter means being mounted on opposite sides of said air inlet, each of said shutter means being engageable with generally one half of said air inlet.
Claim 4
Dependent Claim
28 words
The air diffuser of claim 1 wherein said adjustable shutter means includes air deflector means for directing air moving through said air passage towards said air discharge aperture.
Claim 5
Dependent Claim
86 words
The air diffuser of claim 1 wherein said first side wall is stepped and said second side wall is Substantially flat, said stepped side wall being defined by an upper vertical section, a lower vertical section and a substantially laterally extending shelf, the opposite lateral edges of which are connected to said upper and lower vertical sections, said lower vertical section of said stepped wall, the lower portions of said end walls and the lower portion of said second side wall defining said air discharge aperture.
Claim 6
Dependent Claim
22 words
The air diffuser of claim 1 wherein said first side wall is substantially flat and said second side wall is substantially flat.
Claim 7
Dependent Claim
50 words
The air diffuser of claim 4 wherein said air discharge pattern control means is attached to one of said side walls and the lower edge of the other side wall adjacent said air discharge aperture has an inwardly extending flange serving to constrict the mouth of said air discharge aperture.
Claim 8
Dependent Claim
50 words
The air diffuser of claim 5 wherein said air discharge pattern control means is attached to one of said side walls and the lower edge of the other side wall adjacent said air discharge aperture has an inwardly extending flange serving to constrict the mouth of said air discharge aperture.
Claim 9
Dependent Claim
76 words
The air diffuser of claim 1 wherein said baffle means comprises a V-shaped member, said V-shaped member being mounted in said air passage on said second side wall such that the apex of said V-shaped member faces and closely approaches said air inlet, the apex of said V-shaped member being aligned generally centrally with said air inlet, the inclined legs of said V-shaped member serving to deflect air entering said air passage toward said end walls.
