Definitions
- the present subject matter relates to a ventilation fan that is mounted to a support surface, such as a ceiling in a bathroom or washroom.
- the ventilation fan includes a removably coupled flange mounting system that is intended to improve the installation process and/or the sealing performance of the ventilation fan when installed in a support member, for example, the ceiling.
- Ventilation fans are typically used to ventilate rooms, such as bathrooms and shower areas, in residential, commercial, and industrial structures.
- Existing bathroom ventilation fan assemblies are usually installed in a cutout or cavity formed in a support member, such as a ceiling or wall, during the installation process.
- the ventilation fan assembly which can include various components, namely a grille assembly and a fan housing that includes a motor, a fan wheel or blower that draws air through the grille assembly and into the fan housing, and pre-installed electrical leads for connection to a power source.
- the installer cuts an opening in the ceiling where the ceiling has dimensions that exceed the dimensions of the housing.
- the current installation process tends to leave small gaps between the fan housing and the edge of the ceiling that defines the opening (that receives the housing). It is not uncommon for a gap to be found on all sides of the housing. These gaps are problematic for a number of reasons, including that “conditioned air” from the room in which the fan assembly is installed can migrate upward and through the gap which negatively impacts energy efficiency ratings.
- These small gaps allow unwanted air and moisture to enter the ceiling or wall space, which can cause damage to the components of the bathroom fan ventilation system or other structures (e.g., joists) within a ceiling or wall space. Additionally, unwanted air and moisture can cause mold to develop, which can go undetected for large amounts of time.
- the present disclosure provides a ventilation fan assembly with a removable flange mounting system to facilitate installation of the ventilation fan in a support member.
- the flange mounting system may be installed on a housing of the ventilation fan assembly without the use of tools, and the mounting system is removable, again without the use of tools.
- the flange mounting system is intended to improve the sealing performance of the ventilation fan when installed in the ceiling or wall.
- the subject flange mounting system may contain a bracket, which comprises a top flange, a U-shaped receiver that receives an extent of the lower edge of fan housing including its hem, a depending flange, a plurality of apertures that correspond to apertures on the hem of the fan housing, and a plurality of projections that extend from an interior portion of the receiver. These projections are configured to engage with the cooperatively positioned apertures of the fan housing.
- the flange mounting system may attach to the lower edge or the hem of a fan housing by sliding the receiver portion into engagement with the lower edge/hem. Next, a downwardly directed connection force is applied to the bracket by the hand of the installer such that the projections are actuated or snapped into place with the aligned apertures formed in the housing hem. This engagement may secure the flange to the housing such that when the ventilation fan assembly is inserted into the cavity formed into the ceiling or wall, the flange fills and/or obstructs the gap between the housing and the ceiling opening edge, whereby this interaction prevents unwanted air and humidity from passing through the gap and entering the interior ceiling or wall space.
- an upwardly directed disconnection force can be applied by the hand of the installer to the bracket such that the projections are disengaged from the apertures of the housing hem, which then allows for disconnection of the bracket. Accordingly, the installer can selectively apply a connection force or a disconnection force, by hand, to either couple the bracket to the housing or decouple the bracket from the housing.

- the flange 34 is designed such that when it is installed on the fan housing 20 and the housing 20 is installed in ceiling, the flange 34 extends across the gap (G) between the fan housing 20 and the ceiling opening edge E.
- the flange 34 underlies an extent E 1 of the ceiling 40 that is adjacent to the ceiling opening edge E, wherein the upper surface 51 of the flange 34 underlies and engages the lower surface 40 a of the ceiling 40 .
- the flange 34 overlies an extent E 1 of the ceiling 40 that is adjacent to the ceiling opening edge E, wherein the lower surface 50 of the flange 34 overlies and engages the upper surface 40 b of the ceiling 40 .
- the flange 34 can include openings there through to allow for the installer/user to install elongated fasteners through the flange 34 and into to the ceiling.
- the receiver 36 extends downward from the flange 34 .
- the receiver 36 is configured to receive an extent of the lower periphery of the fan housing 20 , including the flap 30 formed on that lower housing edge 28 .
- the receiver 36 comprises a first leg 52 , a second leg 54 , and a connecting segment 56 that preferably has a curvilinear configuration.
- the flange 34 illustratively extends from the first leg 52 away from the second leg 54 .
- the first leg 52 is coupled to the second leg 54 by the connecting segment 56 , which provides the receiver 36 with a U-shaped configuration in cross-section open on the top in the orientation of FIG. 10 .
- the depending member 46 extends from the second leg 54 and is illustratively formed as a rolled edge providing ease of engagement with the housing 20 and reinforcement to the second leg 54 .
- each of the second leg 54 and the depending member 46 are illustratively tapers to have slanted ends, in opposing directions from each other.
- the first leg 52 is illustratively positioned: (i) substantially perpendicular to the flange 34 and (ii) substantially parallel with the second leg 54 .
- the first leg 52 is spaced apart from the second leg 54 to define a receiver space 59 for receiving connection with the housing 20 . While the first and second legs 52 , 54 are shown substantially parallel to each other, in some embodiments, the first and second legs 52 , 54 may be oriented at angle with respect to each other, provided that angle does not hamper engagement of the receiver 36 with the lower housing edge 28 .
- the height (h 1 ) of the second leg 54 of the receiver 36 is less than the height (h 2 ) of the first leg 52 of the bracket 16 .

In this position, the depending member 46 is substantially parallel with the second leg 54 . In some embodiments, the depending member 46 may be angled with respect to the second leg 54 . For example, the inner angle between the depending member 46 and the second leg 54 may be approximately 45°, preferably 25°, and most preferably 15°. When installed, the depending member 46 is preferably configured to press against an outer wall 66 of the fan housing 20 to act as a biasing member to ensure proper engagement between the lower housing edge 28 and the bracket 16 . This can help create an effective air seal between the fan housing 20 , the removable flange mounting system 14 , and the ceiling or wall.
- the bracket 16 includes at least one projection 38 positioned within the receiver 36 of the bracket 16 .
- These projections 38 may extend from the second leg 54 towards the first leg 52 and may be formed by bending (pressing for relief) a section of the second leg 54 . In the embodiments of FIGS. 1-10 , the projections 38 do not extend through the apertures 48 of the first leg 52 .
- the projections 38 are configured to align with apertures 32 that are formed in the flap 30 (see FIGS. 1-4 ).
- the installer applies an downwardly directed force F on the bracket 16 (relative to the housing 20 in the orientation of FIGS. 2 and 3 ) to place each flap 30 into engagement with the corresponding receiver 36 , such that the flap 30 is within the receiver space 59 , and to force the projections 38 into the apertures 32 of the flap 30 .
- This downwardly (in the orientation of FIGS. 2 and 3 ) directed force is oriented substantially parallel to the proximate wall of the housing 20 and substantially perpendicular to the flange 34 .
- the installer applies a upwardly directed force on the bracket 16 (relative to the housing 20 in the orientation of FIGS. 2 and 3 ) to dislodge the projections 38 of the receiver 36 from the apertures 32 of the flaps 30 .
- the first leg 52 of the bracket 16 may have apertures 48 that are aligned with the projections 38 . These apertures 48 allow the installer to access and apply a force on the projections 38 to encourage disengagement from the apertures 32 .
- the user may insert a tool, such as a screw driver, through the apertures 32 to depress the projections 38 and at the same time apply the upwardly directed force on the bracket 16 (relative to the housing 20 in the orientation of FIGS. 2 and 3 ).
- the bracket 16 may be coupled to the fan housing 20 in other ways such as friction fit between the depending member 46 and the outer wall 66 of the fan housing 20 .
- the projections 38 can be designed to elastically deform under a predetermined load, wherein the projections 38 are be formed from a rubber material, plastic material, or other similar materials.
- the user can orientated the bracket 16 such that the flanges 34 extend outwardly from the fan housing 20 (see FIG. 2 ).
- the installer positions the bracket 16 such that the lower housing edge 28 is aligned with the receiver 36 of the bracket 16 .
- the installer also positions the bracket 16 such that the projections 38 are aligned with the apertures 32 formed in the flap 30 .
- the installer applies the downwardly directed force on the bracket 16 (relative to the housing 20 in the orientation of FIGS.
- the installer may desire to only install one of the brackets 16 , or may desire to install only a reduced length of one of the brackets 16 . To install only part of one bracket 16 , the user U may cut the bracket 16 to a desired length and then follow the above steps.
- the bracket 16 When the fan housing 20 is inserted into the cutout opening formed in the ceiling, the bracket 16 can fill and/or obstruct the gap G between the housing 20 and the ceiling opening edge E. This gap filling can prevent unwanted air and humidity from passing through the gap G and entering the interior ceiling or wall space. In this assembled state, the flange mounting system 14 can provide an improved seal between the ceiling (or wall) and the fan housing 20 .
- the projections 38 are formed on the receiver 36 , and more specifically, on the second leg 54 , however, in some embodiments, the projections 38 may be formed on the first leg 52 , and/or on the flap 30 and corresponding apertures may be formed on the first and/or second legs 52 , 54 of the receiver 36 .
- the flange mounting system 14 may be installed after the fan housing 20 is inserted into the cutout formed in the ceiling without fully removing the housing 20 from the cutout.
- the bracket 16 may configured with the receiver 36 formed with substantially parallel first and second legs 52 , 54 that provide the receiver 36 with a substantially rectangular cross-section. At least one projection 38 may extend from the second leg 54 and is configured to engage with the apertures 32 of the corresponding flap 30 .
- the connecting segment 56 may be coplanar with the flange 34 , such that they have a continuous, planar appearance. As such, the top flange 34 extends substantially perpendicular to the receiver 36 .

Abstract
Description
- This patent application claims the benefit of priority under 35 U.S.C. § 119(e) of U.S. Provisional Application No. 62/675,566, filed on May 23, 2018, entitled “Bathroom Ventilation Fan with a Flange Mounting System,” the contents of which are hereby incorporated by reference in their entirety, including but without limitation, those aspects of devices, systems, and methods for ventilation and mounting of ventilation components.
- The present subject matter relates to a ventilation fan that is mounted to a support surface, such as a ceiling in a bathroom or washroom. Specifically, the ventilation fan includes a removably coupled flange mounting system that is intended to improve the installation process and/or the sealing performance of the ventilation fan when installed in a support member, for example, the ceiling.
- Ventilation fans are typically used to ventilate rooms, such as bathrooms and shower areas, in residential, commercial, and industrial structures. Existing bathroom ventilation fan assemblies are usually installed in a cutout or cavity formed in a support member, such as a ceiling or wall, during the installation process. The ventilation fan assembly, which can include various components, namely a grille assembly and a fan housing that includes a motor, a fan wheel or blower that draws air through the grille assembly and into the fan housing, and pre-installed electrical leads for connection to a power source.
- During a typical installation process, the installer cuts an opening in the ceiling where the ceiling has dimensions that exceed the dimensions of the housing. As a result, the current installation process tends to leave small gaps between the fan housing and the edge of the ceiling that defines the opening (that receives the housing). It is not uncommon for a gap to be found on all sides of the housing. These gaps are problematic for a number of reasons, including that “conditioned air” from the room in which the fan assembly is installed can migrate upward and through the gap which negatively impacts energy efficiency ratings. These small gaps allow unwanted air and moisture to enter the ceiling or wall space, which can cause damage to the components of the bathroom fan ventilation system or other structures (e.g., joists) within a ceiling or wall space. Additionally, unwanted air and moisture can cause mold to develop, which can go undetected for large amounts of time.
- Some existing designs for ventilation fan assemblies have attempted to address this issue by forming a hem around the lower edge of the fan housing. However, these hems do not provide a way to minimize larger gaps between the fan housing and the ceiling (or wall) at the installation location. Even when a hem is formed on the lower edge of the housing, which is typically sheet metal, the housing edge can be inadvertently deformed or displaced during installation, which leads to larger gaps, even if just localized. Thus, there is a tangible need to minimize gaps between a fan housing and a ceiling or wall material, while not compromising the installation process.
- The present disclosure provides a ventilation fan assembly with a removable flange mounting system to facilitate installation of the ventilation fan in a support member. The flange mounting system may be installed on a housing of the ventilation fan assembly without the use of tools, and the mounting system is removable, again without the use of tools. The flange mounting system is intended to improve the sealing performance of the ventilation fan when installed in the ceiling or wall.
- The subject flange mounting system may contain a bracket, which comprises a top flange, a U-shaped receiver that receives an extent of the lower edge of fan housing including its hem, a depending flange, a plurality of apertures that correspond to apertures on the hem of the fan housing, and a plurality of projections that extend from an interior portion of the receiver. These projections are configured to engage with the cooperatively positioned apertures of the fan housing.
- The flange mounting system may attach to the lower edge or the hem of a fan housing by sliding the receiver portion into engagement with the lower edge/hem. Next, a downwardly directed connection force is applied to the bracket by the hand of the installer such that the projections are actuated or snapped into place with the aligned apertures formed in the housing hem. This engagement may secure the flange to the housing such that when the ventilation fan assembly is inserted into the cavity formed into the ceiling or wall, the flange fills and/or obstructs the gap between the housing and the ceiling opening edge, whereby this interaction prevents unwanted air and humidity from passing through the gap and entering the interior ceiling or wall space. In the event it becomes necessary, an upwardly directed disconnection force can be applied by the hand of the installer to the bracket such that the projections are disengaged from the apertures of the housing hem, which then allows for disconnection of the bracket. Accordingly, the installer can selectively apply a connection force or a disconnection force, by hand, to either couple the bracket to the housing or decouple the bracket from the housing.
- Other aspects and advantages of the present disclosure will become apparent upon consideration of the following detailed description and the attached drawings wherein like numerals designate like structures throughout the specification.

- Referring to
FIG. 1 , anillustrative ventilation assembly 12 is shown installed within a ceiling of a bathroom or washroom. Theventilation assembly 12 is shown to include a removableflange mounting system 14 including two L-shaped brackets 16 engaged with afan assembly 18 that is installed within a ceiling opening O defined by ceiling edge E (seeFIGS. 4A and 4B ). Thefan assembly 18 is secured to a support member above the ceiling (e.g., joist hanger) with some portions being arranged above the ceiling (as indicated in broken line inFIG. 1 ). Thefan assembly 18 is illustratively connected with thebrackets 16 to provide sealing between thefan assembly 18 and the ceiling. Although thebrackets 16 are illustratively engaged with the bottom side of the wallboard of the ceiling, in some embodiments, thebracket 16 may be engaged with the top side of the wallboard, and/or may be installed in the wall rather than the ceiling. - Referring to
FIG. 2 , theventilation assembly 12 is shown apart from the ceiling, with thefan assembly 18 decoupled from the mountingsystem 14 for descriptive purposes. Thefan assembly 18 illustratively includes afan housing 20 defining aninlet opening 22 on a bottom side (in the orientation ofFIG. 2 ), and anoutlet opening 24 on a lateral side (in the orientation ofFIG. 2 ) which may optionally be connected with outlet piping. Thefan housing 20 includes a motor and blower assembly 15 (seeFIG. 1 ) for generating a flow of air through the inlet opening 22 into thecavity 26 of thehousing 20 and out through theoutlet opening 24, and optionally through outlet piping. A non-limiting example of a suitable motor and blower assembly can be found within U.S. Patent Publication No. 2014/0063796, published on Mar. 6, 2014, owned by the assignee of this application, the contents of which are incorporated by reference herein, in their entirety, and including but without limitation, those portions directed to motors and/or blowers for ventilation. In the installed position, operation of the motor andblower assembly 15 draws air from the room below theceiling 40 through theventilation assembly 12 for exhaust purposes. Although not shown in the Figures, theventilation assembly 12 also includes a grille assembly connectable to the lower portion of thefan housing 20. When theventilation assembly 12 is properly installed, the grille assembly underlies and covers theinlet opening 22 and the ceiling opening O. The grille assembly includes at least one aperture, typically a plurality of apertures, that allow for the passage of air from the room through theinlet opening 22 and for discharge through thefan assembly 18. The grille assembly also includes at least one light element (e.g., LEDs) and a peripheral frame portion that engages a lower surface of the ceiling external to the ceiling opening O. A non-limiting example of suitable grille assembly can be found within U.S. Patent Publication No. 2014/0063796, published on Mar. 6, 2014, the contents of which are incorporated by reference herein, in their entirety, and including but without limitation, those portions directed to the grille assembly. - As shown in
FIGS. 2-4A and 4B , thefan housing 20 illustratively includes alower housing edge 28 arranged along a lower edge of thehousing 20 that defines theinlet opening 22. Thelower housing edge 28 is illustratively formed on each of the four lateral sides of thehousing 20 about theopening 22, although in some embodiments, thelower housing edge 28 may be formed on fewer than four sides. Thelower housing edge 28 includes a flap or rolledsegment 30 that is bent about aterminal housing edge 58 such that it extends upwardly towards an upper end of thehousing 20 at an outward angle to anouter housing wall 66. Eachflap 30 forms a tapered width extending away from theopening 22, forming a slanted lateral side near each corner of thehousing 20. In some embodiments theflap 30 may be formed as a distinct component secured with thehousing 20. Eachflap 30 illustratively includes at least oneaperture 32, and preferably a plurality ofapertures 32, defined there through to assist in coupling thefan assembly 18 with theflange mounting system 14, as discussed in additional detail herein. Alternatively, theapertures 32 may be configured as detents or recesses formed in theflap 30, whereas the detents and recesses do not extend completely through theflap 30. - Referring back to
FIG. 2 , theflange mounting system 14 illustratively engages with thelower housing edge 28 to couple with thefan assembly 18. Eachbracket 16 of theflange mounting system 14 includes amount flange 34 for engagement with the support, such as the ceiling, to provide sealing between thefan assembly 18 and the ceiling, and areceiver 36 for connection with thefan assembly 18. Thereceiver 36 illustratively includes a number of projections 38 (visible through openings in thereceiver 36 inFIG. 2 ) each corresponding in size and location with theapertures 32 of theappropriate flap 30 of thefan assembly 18. - Referring now to
FIG. 3 , theflange mounting system 14 has been engaged withfan assembly 18. As discussed in additional detail herein, in the installed position thereceiver 36 of eachbracket 16 receives thecorresponding flap 30. Theprojections 38 of eachbracket 16 engage with the correspondingapertures 32 of thecorresponding flap 30. Engagement of theprojections 38 with theapertures 32 establishes an interference fit that can be overcome with the application of a sufficient disconnection force that is directed upward and away from theflap 30. - Referring to
FIG. 4A , a partial cross-section of theventilation assembly 12 taken along line 4-4 inFIG. 1B further illustrates engagement between thefan assembly 18 and theflange mounting system 14. Thereceiver 36 receives theflap 30 therein and engages theprojections 38 with theapertures 32 to prevent disengagement of thereceiver 36 and theflap 30. Theflap 30 can be resiliently formed to maintain pressure against theprojection 38 when engaged with theaperture 32. InFIG. 4A , theventilation assembly 12 is in an “under-mount configuration” where anupper surface 51 of theflange 34 is positioned adjacent alower surface 40 a of theceiling 40. Thelower surface 40 a of theceiling 40, embodied as wallboard, is shown engaged with theflange 34 wherein this engagement provides sealing and/or gap reduction between theceiling 40 and thehousing 20.FIG. 4B is a partial cross-section of theventilation assembly 12 in an “over-mount configuration” where alower surface 50 of theflange 34 is positioned adjacent anupper surface 40 b of theceiling 40. - Referring to
FIG. 5 , the twobrackets 16 are shown in isolation. Eachbracket 16 has a first substantiallylinear section 42 that is joined to a second substantiallylinear section 44. In the illustrative embodiment, thesesections sections bracket 16 are substantially L-shaped, and they form a 90° internal angle, although in some embodiments, any thebrackets 16 may include any suitable shape for mating with the lower edge of thehousing 20.Cutouts 35 are defined in thereceiver 36 of the secondlinear section 44, illustratively formed to have crescent shape, to accommodateprotrusions 37 of thehousing 20 during coupling of thebracket 16 with thehousing 20, as discussed in additional detail herein. - Referring to
FIGS. 6-8 , thesections brackets 16 can be supplied in lengths that exceed the length (11,12) of the corresponding side of thehousing 20, wherein the user can reduce their length, e.g., by cutting them, to the proper length prior to installation. In some embodiments, thesections housing 20 which has lateral sides exceeding the length of thesections brackets 16 do not engage entire lower housing edge, in such embodiments, theapertures 32 may still be arranged to correspond with theprojections 38 despite a difference in length between thesections housing 20. Additionally, thesections section 42 may be substantially longer thensection 44 to fit around arectangular fan housing 20. In a further embodiment, thebracket 16 may have a different shape, such as circular, pentagon, hexagon or any other shape that corresponds to the lower edge of thefan housing 20. -
FIG. 9 shows that eachbracket 16 includes theflange 34, thereceiver 36 formed as a curvilinear member preferably having a U-shaped configuration, a dependingmember 46, a plurality ofapertures 48, and a plurality ofprojections 38. Theflange 34 of thebracket 16, shown as a top flange inFIG. 9 , extends outwardly from thereceiver 36 and is positioned substantially perpendicular thereto. As shown inFIGS. 4A and 4B , theflange 34 is designed such that when it is installed on thefan housing 20 and thehousing 20 is installed in ceiling, theflange 34 extends across the gap (G) between thefan housing 20 and the ceiling opening edge E. In the under-mount configuration ofFIG. 4A , theflange 34 underlies an extent E1 of theceiling 40 that is adjacent to the ceiling opening edge E, wherein theupper surface 51 of theflange 34 underlies and engages thelower surface 40 a of theceiling 40. In the over-mount configuration ofFIG. 4B , theflange 34 overlies an extent E1 of theceiling 40 that is adjacent to the ceiling opening edge E, wherein thelower surface 50 of theflange 34 overlies and engages theupper surface 40 b of theceiling 40. Although not shown inFIGS. 4A and 4B , theflange 34 can include openings there through to allow for the installer/user to install elongated fasteners through theflange 34 and into to the ceiling. - Referring to
FIG. 10 , thereceiver 36 extends downward from theflange 34. As mentioned above, thereceiver 36 is configured to receive an extent of the lower periphery of thefan housing 20, including theflap 30 formed on thatlower housing edge 28. Thereceiver 36 comprises afirst leg 52, asecond leg 54, and a connectingsegment 56 that preferably has a curvilinear configuration. - The
flange 34 illustratively extends from thefirst leg 52 away from thesecond leg 54. Thefirst leg 52 is coupled to thesecond leg 54 by the connectingsegment 56, which provides thereceiver 36 with a U-shaped configuration in cross-section open on the top in the orientation ofFIG. 10 . The dependingmember 46 extends from thesecond leg 54 and is illustratively formed as a rolled edge providing ease of engagement with thehousing 20 and reinforcement to thesecond leg 54. On longitudinal ends, each of thesecond leg 54 and the dependingmember 46 are illustratively tapers to have slanted ends, in opposing directions from each other. - The
first leg 52 is illustratively positioned: (i) substantially perpendicular to theflange 34 and (ii) substantially parallel with thesecond leg 54. Thefirst leg 52 is spaced apart from thesecond leg 54 to define areceiver space 59 for receiving connection with thehousing 20. While the first andsecond legs second legs receiver 36 with thelower housing edge 28. - Returning briefly to
FIG. 9 , the height (h1) of thesecond leg 54 of thereceiver 36, with reference to theflange 34, is less than the height (h2) of thefirst leg 52 of thebracket 16. This configuration helps ensure that theflange 34 is substantially parallel with theterminal edge 58 of thelower housing edge 28, when thebracket 16 is installed. Also, the height (h1) of thesecond leg 54 is preferably large enough to overlap the entirety of thelower housing edge 28 when embodied as a hem. In some embodiments, the height (h1) of thesecond leg 54 may be reduced. In some embodiments, thesecond leg 54 may not extend the entire length (11,12) of thefirst leg 52. - The depending
member 46 extends from theend 60 of thesecond leg 54 and it is positioned such that theinner surface 62 of the dependingmember 46 is in contact with theouter surface 64 of thesecond leg 54. In this position, the dependingmember 46 is substantially parallel with thesecond leg 54. In some embodiments, the dependingmember 46 may be angled with respect to thesecond leg 54. For example, the inner angle between the dependingmember 46 and thesecond leg 54 may be approximately 45°, preferably 25°, and most preferably 15°. When installed, the dependingmember 46 is preferably configured to press against anouter wall 66 of thefan housing 20 to act as a biasing member to ensure proper engagement between thelower housing edge 28 and thebracket 16. This can help create an effective air seal between thefan housing 20, the removableflange mounting system 14, and the ceiling or wall. - To facilitate the coupling of the
bracket 16 to thefan housing 20, thebracket 16 includes at least oneprojection 38 positioned within thereceiver 36 of thebracket 16. Theseprojections 38 may extend from thesecond leg 54 towards thefirst leg 52 and may be formed by bending (pressing for relief) a section of thesecond leg 54. In the embodiments ofFIGS. 1-10 , theprojections 38 do not extend through theapertures 48 of thefirst leg 52. Theprojections 38 are configured to align withapertures 32 that are formed in the flap 30 (seeFIGS. 1-4 ). - Returning briefly to
FIGS. 2 and 3 , to couple thebracket 16 to thefan housing 20, the installer applies an downwardly directed force F on the bracket 16 (relative to thehousing 20 in the orientation ofFIGS. 2 and 3 ) to place eachflap 30 into engagement with the correspondingreceiver 36, such that theflap 30 is within thereceiver space 59, and to force theprojections 38 into theapertures 32 of theflap 30. This downwardly (in the orientation ofFIGS. 2 and 3 ) directed force is oriented substantially parallel to the proximate wall of thehousing 20 and substantially perpendicular to theflange 34. - To disconnect the
bracket 16, the installer applies a upwardly directed force on the bracket 16 (relative to thehousing 20 in the orientation ofFIGS. 2 and 3 ) to dislodge theprojections 38 of thereceiver 36 from theapertures 32 of theflaps 30. To facilitate the disengagement of thebracket 16 from thehousing 20, thefirst leg 52 of thebracket 16 may haveapertures 48 that are aligned with theprojections 38. Theseapertures 48 allow the installer to access and apply a force on theprojections 38 to encourage disengagement from theapertures 32. In particular, the user may insert a tool, such as a screw driver, through theapertures 32 to depress theprojections 38 and at the same time apply the upwardly directed force on the bracket 16 (relative to thehousing 20 in the orientation ofFIGS. 2 and 3 ). In some embodiments, thebracket 16 may be coupled to thefan housing 20 in other ways such as friction fit between the dependingmember 46 and theouter wall 66 of thefan housing 20. In some embodiments, theprojections 38 can be designed to elastically deform under a predetermined load, wherein theprojections 38 are be formed from a rubber material, plastic material, or other similar materials. - To begin installation of the
flange mounting system 14, the user can orientated thebracket 16 such that theflanges 34 extend outwardly from the fan housing 20 (seeFIG. 2 ). Next, as shown inFIG. 2 , the installer positions thebracket 16 such that thelower housing edge 28 is aligned with thereceiver 36 of thebracket 16. The installer also positions thebracket 16 such that theprojections 38 are aligned with theapertures 32 formed in theflap 30. After the installer has properly aligned thebracket 16 with thefan housing 20, the installer applies the downwardly directed force on the bracket 16 (relative to thehousing 20 in the orientation ofFIGS. 2 and 3 ) which in turn displaces theprojections 38 into theapertures 32 of theflaps 30 The engagement between theprojections 38 and theapertures 32 effectively secures theflange mounting system 14 with thefan housing 20. This completes the installation of onebracket 16. The installer then repeats these steps to install theother bracket 16, which completes the installation of theflange mounting system 14. It should be understood, that the installer may desire to only install one of thebrackets 16, or may desire to install only a reduced length of one of thebrackets 16. To install only part of onebracket 16, the user U may cut thebracket 16 to a desired length and then follow the above steps. - When the
fan housing 20 is inserted into the cutout opening formed in the ceiling, thebracket 16 can fill and/or obstruct the gap G between thehousing 20 and the ceiling opening edge E. This gap filling can prevent unwanted air and humidity from passing through the gap G and entering the interior ceiling or wall space. In this assembled state, theflange mounting system 14 can provide an improved seal between the ceiling (or wall) and thefan housing 20. - In the illustrative embodiment, the
projections 38 are formed on thereceiver 36, and more specifically, on thesecond leg 54, however, in some embodiments, theprojections 38 may be formed on thefirst leg 52, and/or on theflap 30 and corresponding apertures may be formed on the first and/orsecond legs receiver 36. - In some embodiments, the
flange mounting system 14 may be installed after thefan housing 20 is inserted into the cutout formed in the ceiling without fully removing thehousing 20 from the cutout. Thebracket 16 may configured with thereceiver 36 formed with substantially parallel first andsecond legs receiver 36 with a substantially rectangular cross-section. At least oneprojection 38 may extend from thesecond leg 54 and is configured to engage with theapertures 32 of thecorresponding flap 30. The connectingsegment 56 may be coplanar with theflange 34, such that they have a continuous, planar appearance. As such, thetop flange 34 extends substantially perpendicular to thereceiver 36. - It is to be understood that all described elements are preferably formed from sheet metal and are bent into the shapes shown and described herein. Other materials, such as plastic may injection molded and used instead of sheet metal. In further embodiments, other materials may be used including, but not limited to, polymers, rubbers, foams, ceramics, other metals, metal alloys, or any other material known to those skilled in the art.

Terms such as top, bottom, front, rear, side, horizontal, vertical, and the like refer to an arbitrary frame of reference, rather than to the ordinary gravitational frame of reference. Thus, such a term may extend upwardly, downwardly, diagonally, or horizontally in a gravitational frame of reference.
- The disclosure is provided to enable any person skilled in the art to practice the various aspects described herein. In some instances, well-known structures and components are shown in block diagram form in order to avoid obscuring the concepts of the subject technology. The disclosure provides various examples of the subject technology, and the subject technology is not limited to these examples. Various modifications to these aspects will be readily apparent to those skilled in the art, and the principles described herein may be applied to other aspects.
- All structural and functional equivalents to the elements of the various aspects described throughout the disclosure that are known or later come to be known to those of ordinary skill in the art are expressly incorporated herein by reference and are intended to be encompassed by the claims. Moreover, nothing disclosed herein is intended to be dedicated to the public regardless of whether such disclosure is explicitly recited in the claims. No claim element is to be construed under the provisions of 35 U.S.C. § 112, sixth paragraph, unless the element is expressly recited using the phrase “means for” or, in the case of a method claim, the element is recited using the phrase “step for”.
- The title, background, brief description of the drawings, abstract, and drawings are hereby incorporated into the disclosure and are provided as illustrative examples of the disclosure, not as restrictive descriptions. It is submitted with the understanding that they will not be used to limit the scope or meaning of the claims. In addition, in the detailed description, it can be seen that the description provides illustrative examples and the various features are grouped together in various implementations for the purpose of streamlining the disclosure. The method of disclosure is not to be interpreted as reflecting an intention that the claimed subject matter requires more features than are expressly recited in each claim. Rather, as the claims reflect, inventive subject matter lies in less than all features of a single disclosed configuration or operation. The claims are hereby incorporated into the detailed description, with each claim standing on its own as a separately claimed subject matter.
- The claims are not intended to be limited to the aspects described herein, but are to be accorded the full scope consistent with the language claims and to encompass all legal equivalents. Notwithstanding, none of the claims are intended to embrace subject matter that fails to satisfy the requirements of the applicable patent law, nor should they be interpreted in such a way.
- All references, including publications, patent applications, and patents, cited herein are hereby incorporated by reference to the same extent as if each reference were individually and specifically indicated to be incorporated by reference and were set forth in its entirety herein.
- The use of the terms “a” and “an” and “the” and “said” and similar references in the context of describing the invention (especially in the context of the following claims) are to be construed to cover both the singular and the plural, unless otherwise indicated herein or clearly contradicted by context. An element proceeded by “a,” “an,” “the,” or “said” does not, without further constraints, preclude the existence of additional same elements. Recitation of ranges of values herein are merely intended to serve as a shorthand method of referring individually to each separate value falling within the range, unless otherwise indicated herein, and each separate value is incorporated into the specification as if it were individually recited herein. All methods described herein can be performed in any suitable order unless otherwise indicated herein or otherwise clearly contradicted by context. The use of any and all examples, or exemplary language (e.g., “such as”) provided herein, is intended merely to better illuminate the disclosure and does not pose a limitation on the scope of the disclosure unless otherwise claimed. No language in the specification should be construed as indicating any non-claimed element as essential to the practice of the disclosure. Numerous modifications to the present disclosure will be apparent to those skilled in the art in view of the foregoing description. Preferred embodiments of this disclosure are described herein, including the best mode known to the inventors for carrying out the disclosure. It should be understood that the illustrated embodiments are exemplary only, and should not be taken as limiting the scope of the disclosure.
- While certain aspects and implementations of the disclosure have been described, these have been presented by way of example only, and are not intended to limit the scope of the disclosure. Indeed, the novel methods and systems described herein may be embodied in a variety of other forms without departing from the spirit thereof. The accompanying claims and their equivalents are intended to cover such forms or modifications as would fall within the scope and spirit of the disclosure.
