Description
AIR VENT WITH FILTER CARRIER
FIELD OF THE INVENTION
The present invention provides an air vent with a filter holder for use with an air duct particularly, of the type for use with a floor mounted 5 air duct.
BACKGROUND
In residential construction it is often common to have air vents in the floor of the house or apartment for delivering air from the heating or air conditioning system to individual rooms of the house or apartment. These 10 vents usually include a face plate with slots which allow air to exit the duct through the face plate. The face plate usually includes vanes, one being arranged adjacent each slot to direct air flow to the left and the right of the air vent.
This arrangement does not allow for air flow to be directed to 15 the front and rear of the face plate. As a result various air deflectors havebeen developed which fit over the face plate and project up from floor level.
These deflectors can be unsightly and can create an obstacle to individuals walking in, or cleaning the room.
Vents often also include an adjustment mechanism which either 20 completely opens or completely closes the vent, but does not allow for direction of the air to a front or rear side of the vent, or for directing more or less air to the right or left side of the air vent.
A second problem found with conventional air vents generally is that dust can collect in the air ducts or be drawn into the heating or 25 coolin~ system at the air intake of the furnace or air conditioner and then be blown throughout the air ducts and into the residence. This leads to the inconvenience of more time being required to clean and remove dust from ~g~
the residence, and can be a health problem for people with allergies or asthma .

Figure 1 is a cross sectional view of the air vent;
Figure 2 is a top view of the filter holder;
Figure 3 is a side view of the re~ister; and Figure 4 is a cross sectional view of the filter holder.
DETAILED DESCRIPTION
Referring to Figure 1 the air vent is shown generally at 10. The 3 ~
air vent 10 is installed at the outlet 12 of an air duct 14 that transfers heated, cooled, or fresh air to a room in a house or other building. The air duct 14 directs air flow substantially parallel to its side wa11s 16 towards theoutlet 12 and then out through the air vent 10 into the room. The air vent S 10 comprises an air register 18 for directing the air leaving the air duct 14,and a filter holder 20 which is removable and reengagable within the air duct 14.
Referring to Figures 1 and 2 the filter holder 20 is sized and arranged for removable and reengagable insertion into the air duct 14, and comprises a front wall 22, a rear wall 24, side walls 26 and 28, filter mounting means 30, and filter access means 32. Each wall 22, 24, 26, and 28 of the filter holder 20 is arranged to lie adjacent an interior surface 34 ofa respective side wall 16 of the air duct 14. The filter holder 20 is generally rectangular and is preferably sized to fit into a conventional floor mounted 15 air duct.
The filter mounting means 30 can support one or more filter elements 36 in one of a number of positions relative to the direction of flow of air 38 in the air duct 14. Each filter element 36 is sized and arranged to extend between the filter holder 20 side walls 22, 24, 26, and 28 thereby 20 insuring that any air passing through the filter holder 20 passes through the filter element 36, removing dust and particulate material from the air.
Referring to Figures 2, 4 and 5 the filter mounting means 30 are arranged on a pair of opposed spaced apart side walls of the filter holder, preferably the front 22 and rear walls 24, and comprise four tracks 25 arranged in two aligned pairs. The aligned tracks extend along the side walls 22 and 24 with each one receiving a respective side edge 42 of a filter element 36, thereby holding the filter element 36 in place between the side 2 ~
walls. Each track is provided by a space 44 between two elongate raised flanges 46 and 48, which define tracks 50, 52, 54, and 56 for guiding and holding the filter element 36.
The first pair of aligned tracks 50 and 52 are arranged near to a S top edge 58 of the filter holder 20 and are arranged to align with one another such that a filter element 36a when in place in the tracks 50 and 52 lies perpendicular to the direction of air flow in the air duct.
The second pair of aligned tracks 54 and 56 are arranged such that the track 54 lies adjacent and below one of the first pair of aligned 10 tracks 50, preferably on the front wall 22, and a second track 56 lies adjacent a bottom edge 60 of the wall opposite, preferably the rear wall 24.
The second pair of tracks 54 and 56 are arranged to align with one another such that the filter element 36b when in place in the tracks 54 and 56 lies at an acute angle to the direction of air flow 38 in the air duct.
A filter element 36c may also be held in place between the tracks 50 and 52 such that the filter element 36 extends between the walls 22, 25, 26, and 28 in an arch shape.
The filter access means 32 allows for periodic removal and replacement of the filter elements 36. The filter access means 32 comprise 20 one of the side walls 26 of the filter holder 20 arranged perpendicular to the front 22 and rear walls 24, and which can be removed from and reengaged to the filter holder 20. This allows for the replacement of the filter elements 36 by removing the filter holder 20 from the air duct 14, removing the removable side wall 26, then sliding one or all of the filter elements 36 25 sideways out from between the tracks which hold them in place. A filter element 36 may be replaced by sliding in a replacement filter element between the tracks and reversing the above procedure.
Referring to Figures 1 and 3 the air vent 10 also includes the air register 18. The air register 18 comprises a face plate 62, air flow directing means 64, and first and second adjustment means 66 and 68.
The face plate 62 covers the outlet end 12 of the air duct 14 5 and has a plurality of slots 70 therethrou~h. The face plate 62 is divided into two portions a first portion 72 which directs air exiting the slots 70 to a leftside of the face plate 62 and a second portion 74 which directs air exiting said slots 70 to a right side of the face plate 62. Air is directed in both the first and the second portions 72 and 74 by vanes 76 fixed adjacent each 10 respective one of the plurality of slots 70. In the first portion 72 the vanes 76 are angled such that air is directed to the left, and in the second portion 74 the vanes 76 are angled such that air is directed to the right.
The air flow directing means 64 are arranged to fit within the air duct 14 extending between the side walls 16, and Iying beneath and 15 adjacent the face plate 62. The air flow directing means 64 include a first air directing means 78 and a second air directing means 80. The first air directing means 78 includes a first plurality of positionally adjustable parallel vanes 82. The first adjustable vanes 82 direct air flow through the first portion 72 of the air register 18. A second air directing means 80 includes a 20 second plurality of positionally adjustable parallel vanes 84. The second adjustable vanes 84 direct air flow through the second portion 74 of the air flow register 18.
The air directing means 64 are controlled by a first adjustment means 66 for selectively repositioning the first air directing means 78 25 through a selectable range of air flow directions, and a second adjustment means 68 for selectively repositioning the second air directing means 80 through a selectable range of air flow directions. The first adjustment means 66 and the second adjustment means 68 are arranged such that they selectively reposition the respective first air directing means 78 and the second air directing means 80 independently of one another.
Both the first and second pluralities of adjustable vanes 82 and 5 84 can each be adjusted to select a direction of air flow between a range of directions between the front and rear sides of the face plate 62.
Both of the pluralities of positionally adjustable vanes 82 and 84 can be repositioned to close a respective first or second portion 72 and 74 of the air flow register 18 preventing air flow through that portion of the 10register 18. One of the first and second portions 72 and 74 of the air flow register 18 can be closed while the other remains open directing all of the air flow to the other portion or both of the first and second portions 72 and 74 of the air flow register 18 can be closed at the same time to close the air register.
15The air vent can be made of any appropriate material, however, it is preferable that the air vent be made of a corrosion resistant material, such as a plastics material.
