Abstract
Abstract An air outlet grille for walls or ceilings for uniformly distributing air in a room without turbulence or drafts. The grille incorporates a plurality of air projecting modules, which may have different projection properties, to conform to the position of the grille in the room by combining modified individual air streams and fluidic distribution of the propelled air and integrating ambient room air forming a uniform coaductive flow of decelerating air in the room involved. The different modules are interchangeable in a particular grille to provide combined air outlet patterns to conform to the shape of the area involved.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
121 words
An air projection grille for wall and/or ceiling mounting and connection with an air duct, said grille comprising a frame having four sides defining an elongated opening, a series of displaceable modules being positionable within said opening to project air in predetermined patterns for integration with ambient air in rooms of varying sizes and shapes, said modules being positionable adjacent one another in the front of the grille and each module having parallel sides with a transverse deflection surface leading to an outlet between said sides, said series of modules having deflection surfaces mounted at different angles with respect to one another and side-by-side V-shaped outlets formed between said surfaces to project air at preselected and different angles through said outlets.
Claim 2
Dependent Claim
121 words
An air projection grille for wall and/or ceiling mounting and connection with an air duct, said grille comprising a frame having four sides defining an elongated opening, a series of displaceable modules being positionable within said opening to project air in predetermined patterns for integration with ambient air in rooms of varying sizes and shapes, said modules being positionable adjacent one another in the front of the grille and each module having parallel sides with a transverse deflection surface leading to an outlet between said sides, said series of modules having deflection surfaces mounted at different angles with respect to one another and side-by-side V-shaped outlets formed between said surfaces to project air at preselected and different angles through said outlets.
Claim 3
Dependent Claim
170 words
An air projection grille for wall and/or ceiling mounting and connection with an air duct, said grille comprising a frame that defines a generally rectangular opening, and a series of displaceable modules that are positionable within said opening to project air in predetermined patterns for integration with ambient air in rooms of varying sizes and shapes, said modules being positionable adjacent one another in the front of the grille and each module having parallel sides with a transverse deflection surface leading to outlet means between said sides, said series of modules having their deflection surfaces mounted at different angles with respect to one another and side-by-side V-shaped outlets of said outlet means formed between said surfaces to project air at preselected and different angles through said outlets, each V-shaped outlet being located between adjacent modules, the sides of said modules having outer edges interfitted with a flange of said frame, said flange extending inwardly from the outer edge of the opening and forming a stop rest for receiving said edges.
Claim 4
Dependent Claim
170 words
An air projection grille for wall and/or ceiling mounting and connection with an air duct, said grille comprising a frame that defines a generally rectangular opening, and a series of displaceable modules that are positionable within said opening to project air in predetermined patterns for integration with ambient air in rooms of varying sizes and shapes, said modules being positionable adjacent one another in the front of the grille and each module having parallel sides with a transverse deflection surface leading to outlet means between said sides, said series of modules having their deflection surfaces mounted at different angles with respect to one another and side-by-side V-shaped outlets of said outlet means formed between said surfaces to project air at preselected and different angles through said outlets, each V-shaped outlet being located between adjacent modules, the sides of said modules having outer edges interfitted with a flange of said frame, said flange extending inwardly from the outer edge of the opening and forming a stop rest for receiving said edges.
Claim 5
Dependent Claim
40 words
The grille of claim 2, wherein a groove in said frame is located adjacent an inner edge of said opening and spring means is retained in said groove to bear against said modules and releaseably retain same in said opening.
Claim 6
Dependent Claim
41 words
The grille of claim 3, wherein the spring means is a V-shaped wire that is retained in said groove and said wire projects from the groove to contact the inner edges of said modules and hold the latter in said opening.
