VENT DIVERTER
An apparatus for diverting air discharged from a forced air vent comprises a sheet of flexible material extending between front and rear edges and first and second side edges, the first and second side edges and the rear edges being securable to corresponding edges of the vent, wherein the front edge is free from the vent and movable between a resting position adjacent to the vent and a raised position when air is discharged through the vent.
1. Field of Invention
The present invention relates to diverters in general and in particular to a method and apparatus for unobtrusively diverting air discharged from a forced air vent.
2. Description of Related Art
Many buildings including many residential constructions utilize forced air systems for either or both of heating and cooling of the buildings. Such forced air systems typically include a central furnace or air conditioner as a heating or cooling source having an associated fan for means of air distribution. The system will also typically include a plurality of ducts extending from the fan to distribute the heated or cooled air throughout the building. Such ducts may be located within a floor or the ceiling of the building and will exit the floor or ceiling through vents.
In particular, and with reference to
One difficulty with such vents is that the air discharged therefrom will be directed in a generally upward direction. This may be problematic for some situations as such vents are typically located proximate around the periphery of rooms proximate to the walls thereof. Accordingly, the air discharged from the vent will be directed in a generally upward direction against the walls or windows of the room and less air may be directed into the middle of the room where the occupants may want it.
Previous attempts to solve the aforementioned problem have been unsatisfactory. In particular, some previous attempts have been to provide a shield or diverter having a rigid arcuate shape extending above the grill which may be secured to the vent by magnets or the like. Examples of such devices may be found in U.S. Pat. No. 3,224,679 issued Dec. 28, 1965 to Meyer and U.S. Pat. No. 1,622,031 issued Mar. 22, 1927 to Elters. Such devices disadvantageously extend a significant distance above the grill and may therefore be prone to being tripped on or damaged by occupants of the room.
SUMMARY OF THE INVENTIONAccording to a first embodiment of the present invention there is disclosed an apparatus for diverting air discharged from a forced air vent comprising a sheet of flexible material extending between front and rear edges and first and second side edges, the first and second side edges and the rear edges being securable to corresponding edges of the vent, wherein the front edge is free from the vent and movable between a resting position adjacent to the vent and a raised position when air is discharged through the vent.
The sheet may be bendable to an arcuate shape cross-section at the raised position. The front edge may be adapted to lift up to 3 inches above the vent in the raised position.
The sheet may be formed of a material selected from the group consisting of plastic, rubber or fabric. The sheet may be formed of polyethylene. The sheet may have a thickness of between 1/32 and ¼ inches. The sheet may be substantially transparent.
The first and second side edges and the rear edge may include tabs extending therefrom. The tabs may extend a sufficient distance to extend around edges of the vent so as to be located thereunder. The tabs may be securable to a bottom surface of the vent. The tabs may be securable to a bottom surface of the vent with adhesives.
Other aspects and features of the present invention will become apparent to those ordinarily skilled in the art upon review of the following description of specific embodiments of the invention in conjunction with the accompanying figures.
In drawings which illustrate embodiments of the invention wherein similar characters of reference denote corresponding parts in each view,
Referring to
The sheet 22 may be formed of any suitable flexible material, such as by way of non-limiting example plastics such as polyethylene, polytetrafluoroethylene, polyvinyl chloride, polypropylene, fabrics, and natural and synthetic rubbers. The sheet 22 may have a thickness selected to permit it to be sufficiently flexible while being strong enough to not be easily torn or damaged. By way of non-limiting example, it has been found that a thickness of between 1/32 and ¼ inch (0.8 and 6 mm) has been adequate although it will be appreciated that different thicknesses may also be useful depending upon the material selected and the size of the vent. The sheet 22 may also be selected to have any color as desired by a user as well as optionally transparent, translucent or opaque.
As illustrated in
Each of the side tabs includes an arcuate portion 42 extending from the sheet and a planar portion 44 which is substantially parallel to the sheet and spaced apart therefrom. The planar portion 44 includes top and bottom surfaces, 46 and 48, respectively. The top surface 46 of the planar portion 44 is located to receive the flange 14 of the vent grill 10 between the top surface 46 and the bottom surface 34 of the sheet 22 and will therefore be spaced apart therefrom by a distance sufficient to receive the flange 14.
The rear tab includes an arcuate portion 52 extending from the sheet and a planar portion 54 which is substantially parallel to the sheet and spaced apart therefrom. The planar portion 54 includes top and bottom surfaces, 56 and 58, respectively. The top surface 56 of the planar portion 54 is located to receive the flange 14 of the vent grill 10 between the top surface 56 and the bottom surface 34 of the sheet 22 and will therefore be spaced apart therefrom by a distance sufficient to receive the flange 14. The side and rear tabs 40 and 52 may also have a width selected to permit the tabs to overlap the flange 14 of the vent grill 10 by a distance sufficient to grip it. In practice it has been found that a width of up to 1.5 inches (38 mm) has been adequate although it will be appreciated that other widths may be useful as well.
In some embodiments the top surface 56 of the rear tab 50 and the top surfaces 46 of the side tabs 40 may include an adhesive, such as, by way of non-limiting example, glue or double sided tape so as to adhere the tabs to the flange. The side tabs 40 and rear tab 50 may be formed of a continuous material with the sheet 22 or may optionally be formed of separate components and secured to the sheet, by adhesives, fasteners or the like.
In operation, the vent grill 10 may be removed from the vent 6 and the sheet applied to the flange 14 such that the side tabs 40 and rear tab 50 extend over and around the flange to bear against the bottom surface thereof as illustrated in

While specific embodiments of the invention have been described and illustrated, such embodiments should be considered illustrative of the invention only and not as limiting the invention as construed in accordance with the accompanying claims.
