Abstract:
An apparatus for controlling air flow from an air-conveying passage through a first opening formed in a wall of a room, said air-conveying passage extending from a floor of said room to a ceiling of said room, said air-conveying passage communicating with an air supply adjacent said floor of said room, said apparatus comprising:a body portion carried by said wall adjacent said first opening in said wall, and said body portion having a first perforate outlet abutting the wall and overlying said first opening in said wall through which air from said air-conveying passage can flow through said first opening in said wall into said room;a selectively positionable air flow control device carried by said body portion that is comprised of a pair of selectively positionable air diverters and disposed in said wall, said flow control device for impeding air flow through said outlet and from said air-conveying passage when said selectively positionable air diverters are disposed in a first position, impeding air flow through said outlet and permitting air flow through an air connecting passage in said wall toward said ceiling of said room when said selectively positionable air diverters are disposed in a second position, and impeding air flow from said air-conveying passage and permitting air flow through said first outlet when said selectively positionable air diverters are disposed in a third position;a manipulable control mechanism disposed in said room that is operably associated with said selectively positionable air flow control device, wherein said manipulable control mechanism is used in positioning said selectively positionable air flow control device, and wherein said manipulable control mechanism comprises a pair of manipulable controllers with one of said manipulable controllers operably coupled to a first one of said selectively positionable air diverters and another one of said manipulable controllers operably coupled to a second one of said selectively positionable air diverters;a second perforate outlet overlying a second opening in said wall, wherein said second perforate outlet and said second opening are both disposed above said first opening in said wall; andwherein said connecting passage is disposed inside said wall and extends vertically from said first outlet to said second outlet.
