Air diffuser cover flap and method

A method of delivering air to a room through standard HVAC processes, comprising:

• a typical room with a typical diffuser for supplying air to said room;
• said diffuser including a plurality of louvers and a lever for controlling said louvers;
• and
• a diffuser covering device made of flexible material and affixed to the wall adjacent to said diffuser, further comprising:
• a front wall, a top and bottom wall, and opposite side walls;
• a lip connected to said top, bottom, and side walls, said lip resting flat against the building wall when air is not being forced through said diffuser;
• and
• a plurality of insets formed into said front wall to accommodate the louver lever of said diffuser;
• wherein said diffuser covering is forced to lift away from said building wall and said diffuser while air is being forced through said diffuser, allowing the air to enter the room, and when said air no longer is blowing into said room, said diffuser covering falls back against said building wall and covers said diffuser, preventing the air that was blown into the room from reentering said diffuser.

A device for the covering of typical air diffusers made of lightweight, flexible plastic, comprising:

• a front wall, including a plurality of structural ridges for increased support;
• top, bottom walls, and opposite side walls forming angles greater than ninety degrees with said front wall;
• a flexible lip connected to each of said walls;
• said lip resting flush against the wall of a building or structure surrounding said diffuser when no air is leaving said diffuser;
• a method of attaching said device to the wall of a building or structure surrounding a diffuser including the use of double-sided adhesive;
• a plurality of insets formed into said front wall to accommodate various placements of louver levers;
• a portion of said lip hinged to allow the covering device to be pushed away from the diffuser by air being blown from said diffuser;

A method of delivering conditioned air to a room through standard HVAC processes, comprising:

• a typical room with a typical diffuser for supplying air to said room;
• said diffuser including a plurality of louvers and a lever for controlling said louvers;
• and
• a diffuser covering device made of flexible plastic and affixed to the wall adjacent to said diffuser, further comprising:
• a front wall, a top and bottom wall, and opposite side walls;
• a hinged lip connected to said top, bottom, and side walls, said lip resting flat against the building wall when air is not being forced through said diffuser;
• a plurality of insets formed into said front wall to accommodate the louver lever of said diffuser;
• and
• a plurality of structural ridges on said front wall for added structural integrity;
• said conditioned air to be either heated or cooled and may or may not pressurize the room to be conditioned;
• wherein said diffuser covering is forced to lift away from said building wall and said diffuser while air is being forced through said diffuser, allowing the air to enter the room, and when said air no longer is blowing into said room, said diffuser covering falls back against said building wall and covers said diffuser, preventing the air that was blown into the room from reentering said diffuser.
