VENT DEVICE FOR USE WITH MEDIUM FOR ALTERING A CONDITION OF
AIR ENTERING AN ENVIRONMENT
Background of the Invention
This invention relates generally to the means and
methods for controlling conditions of the air of an
environment and relates, more particularly, to the vents
through which air is moved by an air handling system into an
environment within which the conditions of the air are desired
to be controlled.
Vents, also known as registers, for communicating,
or conducting, air from the duct or conduit of an air delivery
system into an environment, such as a room of a building, are
well known in the art. Such vents commonly include a body
having a passageway therethrough for receiving air from the
duct or conduit and defining a plurality of vent openings
which direct air flow into the environment. It is also common
for such vents to include a closure mechanism, such as a
louver mechanism, which permits the volume of air communicated
into the environment by way of the vent openings to be
selectively controlled. It would be desirable to provide such
a vent which is adapted to support condition-altering mediums,
such as a filter, through which the air is permitted to pass
in order to condition the air in a desired manner before the
air enters the environment.
Accordingly, it would be desirable to provide a new
and improved vent device through which air is discharged into
an environment by an air-delivery system wherein the device is
adapted to support a condition-altering medium through which
the air is permitted to pass as the air enters the
environment.
Another object of the present invention is to
provide such a vent device wherein a condition-altering medium
can be readily installed within or removed from the device.
Still another embodiment of the present invention is
to provide such a vent device wherein a condition-altering
medium positioned therein can be used to alter the flow of air
permitted to exit the vent device.
Yet another embodiment of the present invention is
CA 02447056 2003-11-07
WO 02/093083 PCT/US01/15478
2
to provide such a vent device which is well-suited for holding
a filter for filtering unwanted materials, such as dust and
pollen, from the air as the air enters the environment.
A further embodiment of the present invention is to
provide such a vent device which is uncomplicated in
construction and effective in operation.
Summary of the Invention
This invention resides in a vent device for
communicating air from an air supply system into an
environment.
The vent device includes a body having a passageway
through which air is permitted to flow from an air supply
system and into an environment, and the passageway inqludes
an opening. In addition, the device includes a housing having
a cavity within which a condition-altering medium is
positionable and having vent openings which permit the flow
of air through the cavity so that a condition-altering medium
positioned within the cavity can alter a condition of the air
which flows through the cavity. The housing is attached to
the body for movement relative thereto between a closed
condition at which the housing is positioned within the
opening of the passageway of the body so that air which flows
through the passageway from the air supply system is conducted
through the cavity of the housing means and an open condition
at which access is provided to the cavity of the housing for
removal of a condition-altering medium contained in the cavity
or for placement of a condition-altering medium into the
cavity.

Detailed Description of the Illustrated Embodiments
Turning now to the drawings in greater detail and
5 considering Figs. 1-14, there is illustrated an embodiment,
generally indicated 10, of a vent device within which features
of the present invention are incorporated. The vent device
is designed for use with an air supply, or air-delivery,
system such as, for example, the air handling system of a
10 central heat and air conditioning unit of a building to
condition the air being conducted into a room of the building.
More specifically, the vent device 10 is adapted to be mounted
in the floor, wall or ceiling of a room of the buildiang for
conditioning the air being communicated, or conducted from an
air duct into the room. The conditioning of the air being
conducted into the room by the air is performed by a filter
(described herein) mounted within the vent device 10 so that
the air being conducted into the room is relatively free of
dust, pollen and other particulate desired to be removed from
the air by the filter.
Although the vent device 10 is described herein as
being used to filter the air being conducted into a room so
that filtered air enters the room, it will be understood that
other air-conditioning mediums, such as room deodorizers (or
other scent-laden mediums) or breathable medicines, can be
supported within a device, like that of the vent device 10,
in accordance with the broader aspects of the present
invention. Furthermore, although the vent device 10 described
herein is intended to be used for conditioning the air
entering a room, comparable vent devices can be designed and
used at the outlets of air-delivery systems used for
delivering air into other environments, such as the interior
of an automobile or the cab of a truck, in accordance with the
broader aspects of the present invention. Accordingly, the
principles of the present invention can be variously applied.
With reference again to Figs. 1-14, the vent device
10 includes a body 12 within which is housed a platen-like
CA 02447056 2003-11-07
WO 02/093083 PCT/US01/15478
6
filter housing 14. Both the body 12 and the filter housing
14 can be fabricated from a strong durable plastic, but it
will be understood that various other fabricating materials
could be used, including various metallic materials.
In the embodiment 10 of Figs. 1-14, the body 12
includes rectilinear walls 16 joined at four corners to define
an air flow passageway 18 which permits the passage of air
vertically through the body 12. The walls 16 also define a
lowermost opening 20 which establishes fluid communication
between the passageway 18 and an operatively associated duct
22 (Fig. 12), and define an uppermost opening 24 within which
the filter housing 14 is accepted so that the filter housing
14 is at least partially disposed within the passageway 18.
The body 12 also includes an outwardly-directed
mounting flange 26 which substantially encircles the uppermost
opening 24 for engaging a supporting surface 28 (see Fig. 12)
such as the surface of a wall, floor or ceiling, when the vent
device 10 is operatively installed taithin a duct 12 of the
wall, floor or ceiling. Therefore and as illustrated in Fig.
12, in a typical installation, at least a portion of the body
12 is accepted by an opening 30 in the duct 22 of a wall,
floor or ceiling, and at least a portion of the walls 16
engages the duct 22 so that the opening 20 is in fluid
communication with the air passageway of the duct 22.
Furthermore, the mounting flange 26 is positioned in
engagement with the supporting surface 28 of the wall, floor
or ceiling so as to stabilize the body 12 when positioned
therein. Preferably, the walls 16 of the body 12 are sized
to accommodate force-fit insertion into the duct 22. To
facilitate this force-fit engagement, protruding detent
members 32 can be provided on, or formed along, the exterior
of the walls 16.
In the illustrated embodiment of the vent device 10,
the filter housing 14 is closely received and pivotally
secured in the passageway 18 so as to serve as a closure for
the passageway 18. In this connection, the filter housing 14
is pivotally secured to the body 12 proximate a rearward edge
CA 02447056 2003-11-07
WO 02/093083 PCT/US01/15478
7
portion 34. Within the depicted vent device 10, this pivotal
mounting of the filter housing 14 is accomplished with a pair
of oppositely-disposed pivot pins 36 which extend from the
filter housing 14 and which are received in openings 38
provided,in the body 12. It will be noted that alternative
openings 38' can be provided (see Figs. 6-9) for receiving the
pins 36 so that the direction in which the filter housing 14
pivots open can be reversed if desired.
It follows, therefore, that the filter housing 14
is pivotally connected to the body 12 to accommodate a pivotal
movement of the housing 14 from a closed condition, as
illustrated in Figs. 1-7 at which the plane of the housing 14
is oriented substantially horizontally (and the upper surface
of the housing 14 is substantially flush with the mounting
flange 26), and an open condition, as illustrated in Figs. 8-
10 at which the plane of the housing 14 is disposed
substantially vertically (and the upper surface of the housing
14 is positioned substantially vertically). As will be
apparent herein, by positioning the filter housing 14 in its
open (Figs. 8-10) condition facilitates the removal or
installation of a filter therein.
Within the depicted vent device 10, at least the
inner portion 40 of the filter housing 14 is designed to be
moved into a snap fit relationship within the passageway 18
when moved to its closed condition so that the filter housing
14 is less likely to inadvertently pivot to an open position.
Such a snap-fit relationship can be had by providing the body
12 with protruding detent members 42 (Figs. 6 and 7) which
snap into corresponding openings 44 provided in the walls 16
of the body 12 when the filter housing 14 is moved to its
closed position within the passageway 18. However, it will
be recognized by those skilled in the art that other
mechanisms can be used to releasably secure the filter housing
14 in its closed position within the passageway 18.
As best illustrated in Fig. 10, the filter housing
14 includes means defining a filter slot 46 having an
elongated slot opening 47 opening out of a forward edge
CA 02447056 2003-11-07
WO 02/093083 PCT/US01/15478
8
portion 48 of the housing 14 and so that the housing 14
defines inner and outer walls 50 and 52, respectively. The
inner wall 50 of the housing 14 is provided with a plurality
of vent openings 54 which allow air to be communicated from
the duct 22 into the filter slot 46, and the outer wall 52
defines a plurality of vent openings 56 whose openings are in
registry with the vent openings 54 of the inner wall 50, and
which allow air to be communicated from the filter slot 46
into a room of a building. Accordingly, the vent openings 54
and 56 provide communication of the air from the duct 22 (Fig.
12) through the filter housing 14 and into a room of a
building.
Por purposes of filtering the air which is being
introduced into the room through the duct 22, a filter 58 is
removably received by the filter slot 46 of the filter housing
14. In the depicted embodiment 10 and as best shown in Figs.
10 and 11, the filter 58 includes means providing an enclosure
60 which, in turn, defines a cavity 62 for supporting a filter
medium, or material 63. The filter material 63 of the
depicted filter 58 is adapted to trap unwanted dust, pollen
and other particulate matter desired to be prevented from
entering the room of the building by way of the vent 10. In
the alternative (or in addition), a scented substance, such
as an air deodorizer or freshener can be positioned within the
cavity 62 to scent or deodorize the air passing through the
vent device 10. Moreover, medication adapted to be absorbed
by or evaporate within the air moving through the vent 10 can
be positioned within the cavity 62 so that it is dispersed
into a room of the building.
In connection with the foregoing, the enclosure 60
of the filter 58 includes inner and outer walls 64 and 66,
respectively, disposed on opposite sides of the filter
material 63. The inner wall 64 is provided with a plurality
of vent openings 68, and the outer wall 66 is provided with
a plurality of vent openings 70 which are in registry with the
vent openings 68 to permit air flow through the filter 58.
The vent openings 68 and 70 of the depicted filter 58 are
CA 02447056 2003-11-07
WO 02/093083 PCT/US01/15478
9
configured and spaced from one another so that when the filter
58 is positioned within the housing 14, the openings 68 and
70 can be aligned (i.e. positioned in registry with) the vent
openings 54 and 56.
Along the lines of the foregoing, in the depicted
vent device 10, the length L (Fig. 12) of the filter slot 46
is greater than the length L' of the filter 58 (see Fig. 12)
to accommodate a longitudinal shifting of the filter 58 within
the slot 46. This permitted shifting allows the filter 58 to
be slidably moved between a position at which the vent
openings 68 and 70 are aligned with the vent openings 54 and
56 and a position at which the vent openings 68 and 70 are out
of alignment with the vent openings 54 and 56 and the inner
and outer walls 64 and 66 of the filter 58 totally obstruct
air flow between the vent openings 54 and 56.
For example and as seen in Fig. 12 (at which the
filter housing 14 is positioned in a closed position), the
filter 58 has been positioned along the length of the filter
housing 14 so that the vent openings 68 and 70 of the filter
58 are aligned with the vent openings 54 and 56 of the filter
housing 14. When the filter 58 is positioned in this Fig. 12
position, air from the duct 22 is permitted to flow into the
room through the filter 58, the direction of the air flow
being indicated by the arrows 73.
On the other hand and as shown in Fig. 13, the
filter 58 is positioned along the length of the housing 14 so
that the vent openings 68 and 70 of the filter 58.are
partially (rather than totally) aligned with the vent openings
54 and 56 of the filter housing 14. Consequently, air flow
into the room through the filter 58 is partially obstructed.
Further still and as shown in Fig. 14, the filter 58 is
positioned along the length of the housing 14 so that the vent
openings 68 and 70 of the filter 58 are wholly out of
alignment with the vent openings 54 and 56 of the filter
housing 14 and, in fact, are covered by the enclosure walls
64 and 66. Consequently, air flow into the room through the
filter 58 is totally obstructed or shut off. Thus, the air
CA 02447056 2003-11-07
WO 02/093083 PCT/US01/15478
flow through the vent device 10 into the room can be
controlled by adjusting the longitudinal position of the
filter 58 along the length of the filter slot 46.
To facilitate the adjustment of the position of the
5 filter 58 along the filter slot 46, the filter 58 is provided
with an actuator 71 (Figs. 10 and 11) which is accessible when
the filter housing 14 is seated within the body opening 24 (as
shown in Fig. 1). Therefore, by sliding the actuator 71 to
one of a number of possible positions along the length of the
10 filter slot 46, the air flow through the vent device 10 can
be controlled without pivoting the filter housing 14 relative
to the body 12 and out of its normal operating position. It
will also be noted that in the depicted filter embodiment 58,
the filter enclosure 60 is provided with an access opening 72
(Fig. 11) opposite the side of the actuator 71 which permits
the interior of the enclosure cavity 62 to be accessed. This
opening 72 permits the filter material 63 to be periodically
replaced, as necessary, so that the filter enclosure 60 can
be reused. This filter-replacement feature notwithstanding,
it is contemplated that the entire filter 58 can be
disposable, thus obviating the need for the access opening 72.
With reference to Figs. 15-19, there is illustrated
an alternative embodiment, generally indicated 10A, embodying
features of the present invention. Components of the vent
device 10A which are identical to those of the vent device 10
of Figs. 1-10 and 12-14 bear the identical reference numerals
followed by the alphabetic character "A". As best illustrated
in Fig. 16, the filter housing 14A of the vent device 10A
pivotally engages the body 12A proximate a first end portion
74 (rather than proximate the rearward edge portion 34) so
that access to the filter 58A is provided by pivoting the
second end portion 76 relative to the body 10A outwardly.
Further, alternative openings 38A' can be provided for
pivotally receiving the pins 36A so that the direction in
which the filter housing 14A pivots can be reversed if
desired. Further still and as an alternative to accessing the
filter housing 14A from the first end portion 74, the filter
CA 02447056 2003-11-07
WO 02/093083 PCT/US01/15478
11
slot which receives the filter 58A can be provided in the
second end portion 76 of the filter housing 14 as illustrated
by the broken lines at 47A' in Fig. 19.
With reference to Figs. 20-25, there is illustrated
still another embodiment, generally indicated IOB, of a vent
device embodying features of the present invention.
Components of the vent device 10B which are identical to those
of the vent device 10 of Figs. 1-10 and 11-14 accordingly bear
the same reference numerals followed by the alphabetic
character "B". In this embodiment 10B, the filter housing 14B
is connected to the body 12B to permit the passageway 18B of
the body 12B to telescopes into and out of the body 12B
between lower (i.e. a closed) position and an upper (Fig. 21)
position at which access is provided to the filter 58B
positioned within the filter housing 14B. In this regard, the
filter housing 14B is provided with four mounting shafts 78
which extend outwardly from the inner wall 50B of the filter
housing 14B at the four corners thereof. Moreover, the body
12B is provided with four operatively-associated mounting
brackets 80, each of which is provided with a hole 82
therethrough for slidably receiving a corresponding one of the
mounting shafts 78. Further, in the depicted embodiment 10B,
each of the mounting shafts 78 is provided with a stop member
84 at its distal end which prohibits the distal end of the
mounting shaft 78 from moving through the hole 82 in the
mounting bracket 80. Accordingly, the filter housing 14B can
be moved relative to the body 12B between an operative
position (as illustrated in Figs. 20, 22 and 24) wherein the
filter housing 14B is positioned within the passageway 18B and
an unseated position (as illustrated in Figs. 21, 23 and 25)
at which the filter 58B is accessible within the housing 14B
for removal and/or replacement of the filter 58B.
With reference to Figs. 26-30, there is shown a
further embodiment, generally indicated 10C, of a vent device
within which features of the present invention are
incorporated. Components of the vent device 10C which are
identical to those of the aforedescribed vent device 10 bear
CA 02447056 2003-11-07
WO 02/093083 PCT/US01/15478
12
the same reference numerals followed by the alphabetic
character "C". The vent device lOC is designed for mounting
proximate the intersection of a ceiling and wall, or proximate
the intersection of a floor and a wall, of a building. As
illustrated, the body 12C of the vent device 10C is configured
so that a rear wall 86 is defined which, upon installation of
the vent device 10C, is positioned adjacent the wall surface
88 (Fig. 28). Further, the body 12C defines a supporting wall
90 for engaging the supporting surface 28C of the floor and
ceiling. In order to advantageously introduce air into the
building, the opening 24C is defined in a diagonal plane
relative to the rear wall 86 and the surrounding wall 90, and
the filter housing 18C is mounted in the opening 24C to
likewise be oriented in a diagonal plane relative to the rear
wall 86 and the supporting wall 90. It will be noted that the
body 12C includes first, second, third and fourth edge
positions 92, 94, 96 and 98, respectively, which define the
diagonally disposed opening 24C. The filter housing 14C can
be pivotally mounted to the body 12C for movement about a
pivotal axis oriented parallel and adjacent to any of the edge
portions 92, 94, 96 or 98. For example, in Figs. 26-28, the
pivot pins 36C are received by openings 38C which are provided
in the opposing sidet,ralls 100 and 102 of the body 12C so that
the filter housing 14C pivots on an axis parallel and adjacent
the first edge portion 92 of the body 12C. In Fig. 29, the
pivot pins 36C have been mounted in the alternative holes 38C'
so that the filter housing 14C pivots on an axis parallel and
adjacent the second edge portion 94 of the body 12C.
Alternatively and as illustrated in Fig. 30, the openings 38C
can be provided in opposing interior walls 104 and 106 so that
the filter housing 14C is permitted to pivot about an axis
oriented parallel and adjacent one of the edge portions 96 or
98.
With reference to Figs. 31 and 32, there is
illustrated a further embodiment, generally indicated lOD,
within which features of the present invention are
incorporated. Components of the vent device lOD which are
CA 02447056 2003-11-07
WO 02/093083 PCT/US01/15478
13
identical to those of the aforedescribed vent device 10
accordingly bear the same reference numerals followed by the
alphabetic character "D". The vent device z0D is intended to
be mounted in a ceiling or wall, and the body 12D defines a
rearward wall 108 which engages the supporting surface 28D of
the ceiling or wall. In this regard, the rearward wall 108
can be secured to the supporting surface with suitable
mechanical fasteners such as with screws 110.
Rather than being secured in the passageway 18D as
is the case with the above-described embodiments 10, 10A, 10B
and 1oC, the filter housing 14D of the vent device 10D is
secured over the opening 24D so as to establish fluid
cbmmunication between the passageway 18D and the filter
housing 14D. More specifically, the body 12D of the depicted
embodiment 12D defines an angular lip 112 disposed proximate
the perimeter of the opening 24D, and the filter housing 14D
defines an interlocking lip portion 114 which engages and
interlocks with the angular lip 112 of the body 12D to secure
the filter housing 14D to the body 12D. It will also be noted
that the outer wall 52D of the filter housing 14D is spaced
from the outer wall 66D of the filter 58D as the filter 58D
is seated in the filter housing 14D. In order to support the
filter 58D in its desired position, the filter housing 14D is
provided with at least one, and preferably a plurality of,
supporting ribs 116 which extend across the interior of the
filter housing 14D (Fig. 32). The supporting ribs 116 are
preferably disposed between adjacent openings 56D so as not
to disrupt the flow of air moving through the housing 14D.
As with the aforedescribed vent devices, the filter 58D of the
vent device 10D is releasably received by the filter slot 46D
and is slidable along the length of the slot 46D between
alterative positions to adjust the volume of air communicated
through the filter housing 14D.
It follows from the foregoing that a vent device has
been described for use with a removable filter which, when
used together, provide significant advantages over the prior
art. The vent device allows air flow into a room to be easily
CA 02447056 2003-11-07
WO 02/093083 PCT/US01/15478
14
controlled and allows the air entering an environment, such
as a room, to be conditioned (e.g. filtered) to remove dust,
pollen and/or other particUlate. Furthermore and if desired,
scented materials can be incorporated into a filter positioned
within the vent device to deodorize a room and/or medication
can be positioned within a filter for dispersal into a room
by way of the vent device.
However, while a preferred embodiment has been shown
and described, it will be understood that numerous
modifications and substitutions can be had to the
aforedescribed embodiments without departing from the spirit
of the invention. For example, although several of the
aforedescribed embodiments have been shown and described as
including pivot pins for pivotally conhectirig a filter housing
to a body of the device, the housing and body can be connected
to one another by means of a strap (commonly referred to in
the art as a living hinge) which joins the filter housing to
the body. For example, there is shown in Fig. 33 a cross
section of a filter embodiment 10E having a body 12E and a
filter housing 14E which are pivotally connected to one
another by way of a strap 130 which joins the housing 14E to
the body 12E and which permits the housing 14E to be pivotally
moved relative to the body 12E (in either of the directions
indicated by the arrows 132 and 134) between a closed and open
conditions. If the filter housing and body are formed as a
single piece unit molded, for example, out of a suitable
plastic, the strap 130 can be integrally formed with the
housing and body. Accordingly, the aforedescribed embodiments
are intended for the purpose of illustration and not as
limitation.
