The method further includes the step of mounting the electric box with respect to the cover. The method still further includes the step of mounting the cover and electric box with respect to the ceiling surface such that at least a portion of the electric box extends within an air conditioning port in the ceiling surface.

[0040] Example embodiments that incorporate one or more aspects of the present invention are described and illustrated in the drawings. These illustrated examples are not intended to be a limitation on the present invention. For example, one or more aspects of the present invention can be utilized in other embodiments and even other types of devices. Moreover, certain terminology is used herein for convenience only and is not to be taken as a limitation on the present invention. Still further, in the drawings, the same reference numerals are employed for designating the same elements.

[0041] Turning to the shown example of FIG. 1, an air distribution apparatus 101 for an air conditioner is shown. As shown schematically in FIG. 3C, the air distribution apparatus 101 can be mounted with respect to an air conditioning port 108 in a ceiling surface 111. The ceiling surface 111 can be a surface of a building such as a residential or commercial establishment, a vehicle such as a recreational vehicle, a motor home, a train, a boat, a plane, or any type of structure in which the air conditioning port 108 is located adjacent the ceiling surface 111. As further shown in FIG. 3C, an air conditioner 107 may be installed above the ceiling surface 111 or may abut against a roof surface 113 above the ceiling surface 111. FIG. 2 shows an exploded view of an example embodiment of the air distribution apparatus 101. The air distribution apparatus 101 can include a bracket structure and an air distribution device. The air distribution device can further comprise an air distribution template 102 and an air distribution cover 103.

[0042] As shown in FIGS. 2, 3A, 3B and 3C, the bracket structure can comprise a pair of brackets 104, 105. In one example, the two brackets 104, 105 are substantially identical so as to create a mirror image of one another when they engage longitudinally opposite sides of the air distribution device. The number of brackets constituting the bracket structure can vary and it is possible to have two brackets that are not identical to one another. As shown in FIGS. 3A and 3B, the bracket 104 and/or 105 of FIG. 3A can include a body portion 110 and a protrusion 112 that extends from the body portion 110. In an assembled position, the body portion 110 can be oriented vertically although non-vertical orientations may be provided in further examples. As further shown, the protrusion 112 can extend horizontally at an approximate 90° angle with respect to the body portion 110 although other angle orientations may be provided in further examples. In one example, the body portion 110 can include truss structures 114 that extend substantially from top to bottom of the body portion 110 in order to increase the rigidity of the bracket 104 or 105 and vertically reinforce the bracket 104 or 105. In one example, the truss structure 114 can comprise a network of reinforcing ribs although other truss structures may be used in further examples. In the illustrated example, the truss structure 114 can comprise a plurality of vertical and angled ribs. The bracket 104 or 105 can be substantially C-shaped in cross-section in order to increase rigidity and provide appropriate mounting surfaces. The bracket 104 or 105 can be fabricated with metal, plastic, composite or any other material that is sufficiently rigid to withstand the mounting forces and other operation forces. As shown in FIG. 3C, the body portion 110 may be mounted so that the mounting portion at least partially extends into the air conditioning port 108 in the ceiling surface 111. As shown in FIGS. 2 and 3C, the bracket 104 and/or 105 can be secured to the air conditioner 107 through fasteners 109, such as mounting bolts, machine screws or the like. The fasteners 109 can be inserted into vertical fastener openings 116 extending through the body portion 110. As shown in FIG. 3C, the bracket 104 or 105 will be fastened to the air conditioner 107 so that an abutment surface 118 of the protrusion 112 abuts against the ceiling surface 111. The air distribution device can then be mounted to the bracket structure so that the air conditioner 107 can be in fluid communication with the air distribution device. It is also possible to assemble at least a portion of the air distribution device with the bracket structure and then mount this portion of the air distribution device with respect to the ceiling surface 111.

[0043] FIGS. 7 and 8 show the example brackets 104, 105 and the example air distribution template 102 in an exploded state and assembled state respectively. The brackets 104, 105 include features that enable mounting of the brackets to the air distribution template 102. As shown in FIG. 8, a semi-circular locating tab 120 (see also FIGS. 3A and 3B) and feet 122, 124 (see also FIG. 3B) of the protrusion 112 of the body portion 110 fit into recessed portions 126, 128 (see also FIG. 5) of the air distribution template 102 respectively. The feet 122, 124 are located at the bottom of the protrusion 112 and can be symmetrically disposed on the bracket 104 or 105. In one example, the air distribution template 102 can be provided with first recessed portions 126 on both of the longitudinally opposite sides of the air distribution template 102 while second recessed portions 128 are provided only on one longitudinal side of the air distribution template 102. As shown in FIG. 9, the air distribution template 102 also includes mounting tabs 130 (see also FIG. 6) which are extensions of wall-like portions 132 and mate with horizontally extending apertures 134 (see also FIG. 4) on the bracket 104 or 105. The horizontally extending apertures 134 can be slots, openings, grooves or the like. As shown in FIG. 10, the protrusion 112 of the bracket 104 or 105 also includes indented portions 136 (see also FIG. 4). As shown in FIG. 10, the indented portions 136 are configured to facilitate a snappingly interlocked connection of the bracket 105 with receiving slots 138 (see also FIG. 5) of the air distribution template 102. FIGS. 4 and 5 also show the brackets 104 or 105 including hooks 140 (see FIG. 4) that become snappingly interlocked with latches 142 (FIG. 5) on the air distribution template 102. Both of the brackets 104 and 105 are equipped with these features so that each bracket 104 or 105 can be placed on either of the longitudinally opposite sides of the air distribution template 102. Thus, it will be appreciated that using identical brackets can reduce inventory requirements and complications during assembly.

[0044] In the present embodiment, on one side of the air distribution template 102, the horizontally extending apertures 134 of the bracket 104 are used for fastening with the mounting tabs 130 of the air distribution template 102 (see FIG. 9). On the other side of the air distribution template 102, the indented portions 136 and the hooks 140 of the bracket 105 are used for fastening (see FIG. 10). Moreover, the air distribution template 102 is shaped and dimensioned to undergo some deformation before accomplishing connection. Various parts of the air distribution template 102 are accommodated with apertures for fastening the air distribution template 102 and the bracket structure with respect to the air conditioning port. The air distribution template 102 is also provided with openings 144 (see FIG. 5) for alignment with corresponding vertical fastener openings 116 (see FIG. 3A) to allow passage of corresponding fasteners 109. Moreover, a knockout 145 (see FIG. 5) can be provided on the air distribution template 102 for use of an optional corresponding center vertical fastener opening 116 (see FIG. 3A).

[0045] FIGS. 11A and 11B show the air distribution template 102 exploded from the air distribution cover 103. The air distribution template 102 has a substantially flat body portion 146 (see also FIG. 5) which can be horizontally oriented after assembly and includes features for accommodating various components and for channeling return and supply air. The air distribution template 102 can be molded with plastic, resin or composite or other material that is sufficiently flexible to deform and engage the bracket structure while capable of sustaining mounting forces. The air distribution template 102 can include a first opening 148 (see FIG. 8) to supply air to an air conditioner 107 by way of a supply air duct 106 (see FIG. 2). Once installed the supply air duct 106 can establish fluid communication between the first opening 148 and the supply port of the air conditioner 107. The supply air duct 106 can be generally of soft material such as fabric so that it can be secured to the air distribution template 102 via a ring 150 that snaps into the first opening 148, as shown in FIG. 2. Excess fabric can be cut off so that the supply air duct 106 is flush with the air distribution template 102 after the ring 150 is snapped in. As shown in FIG. 19, the supply air duct 106 can be secured to the basepan adaptor with wire tie, wire form or hose clamp. The basepan duct adaptor perimeter is reshaped but still snaps to the basepan. Double stick foam may also be used to supplement attachment to the basepan adaptor or screws can be used as an alternative.

[0046] The air distribution template 102 is also provided with a second opening 152 (FIG. 8) for an electric box 154 (FIG. 2) which can be secured to the air distribution template 102 by a snap-in mechanism. The electric box 154 (FIG. 1) can be secured to the air distribution template 102 so that it is minimally, at least partially, or substantially submerged or extended through the air distribution template 102. Such an arrangement between the electric box 154 and the air distribution template 102 can be beneficial by reducing the overall thickness of the air distribution apparatus 101. The air distribution cover 103 can also include a control panel 156 (see FIG. 13) that may be configured to accommodate control knobs 158. The control knobs 158 allow a user to operate the air conditioner 107. As shown in FIG. 18B, the control knobs 158 are in operative engagement with shafts 160 extending from the electric box 154. As shown in FIG. 18B, in the illustrated example embodiment, each control knob 158 includes a socket 162 into which a hexagonal ball 164 at the end of the shaft 160 is inserted. A radial protrusion 166 on the hexagonal ball 164 can be configured to engage a slot 168 provided in the socket 162 so that rotational movement of the control knob 158 is transmitted to the shafts 160. The radial protrusion 166 and the ball-socket connection can provide some margin of error in the alignment of the socket 162 and the shafts 160. In further examples, other structure can be incorporated to provide the operative engagement between the knobs and the shafts. For example, a resilient link can be provided to accommodate some margin of error in the alignment of the knobs and the shafts. Moreover, variations of the hexagonal ball 164 are a hexagonal ball without the protrusion 166 and the slot 168 or a spherical ball with the protrusion 166 and the slot 168. The electric box 154 can include an optional bottom snap-in cover 155 (see FIG. 1) that is placed after the wires are connected.

[0047] As shown in FIG. 11B, the air distribution template 102 is further provided with a first pair of template barrier elements 170, 172 and a second pair of template barrier elements 174, 176 to separate return air and supply air or to channel supply air from the air conditioner 107 to air vents 178, 180, 182, 184 of the air distribution cover 103. As shown in FIGS. 11A and 12, the air distribution cover 103 has a bottom wall 186 and a side wall 188, and is provided with return air areas 190, 192 and supply air areas 194, 196, 198, 200, 202. This embodiment of the air distribution cover 103 has a substantially curvilinear shape. The air distribution cover 103 can include two symmetrically located, perforated portions defining the return air areas 190 and 192 and allowing entry of return air into the air distribution apparatus 101. In this embodiment, a pair of cover barrier elements 204, 206 and the first pair of template barrier elements 170, 172 separate the return air areas 190, 192 from the supply air areas 194, 196, 198, 200, 202 and help channel supply air to the side air vents 180, 184 and an end air vent 178. The second pair of template barrier elements 174, 176 also help channel supply air to the side air vents 180, 184 and another end air vent 182. In one example, the cover barrier elements 204, 206 and the first pair of template barrier elements 170, 172 can cooperate to form a double-barrier structure 208, 210 (FIG. 12) for each return air area 190, 192 to ameliorate insulation of the supply air from the return air. In another example, as shown, the cover and template barrier elements 204, 206, 170, 172, 174, 176 can be substantially L-shaped wall-like structures although other structures can be used in further examples. The cover barrier elements 204, 206 may extend upwardly from the bottom wall 186 of the air distribution cover 103 toward the air distribution template 102 (see FIG. 11A) while the first and second pairs of template barrier elements 170, 172, 174, 176 can extend downwardly from the body portion 146 of the air distribution template 102 toward the air distribution cover 103 (see FIG. 11B). The double-barrier structures 208, 210 are respectively formed by one of cover barrier elements 204, 206 and corresponding template barrier elements 170, 172. It will be appreciated that the two corresponding barrier elements 204, 170 and the two corresponding barrier elements 206, 172 can be substantially similar in shape and stand closely parallel to one another after the air distribution cover 103 and the air distribution template 102 are assembled. As such, an insulation gap such as an air gap may be formed between the cover barrier element and the template barrier element in each double-barrier structure 208, 210. A person of ordinary skill in the art will appreciate that variations in the arrangement, shape or number of the supply and return air areas arising from different embodiments of the air distribution template and the air distribution cover are within the scope of this invention.

[0048] FIG. 12 shows the air distribution template 102 assembled onto the air distribution cover 103. The present embodiment of the air distribution cover 103 can include two side air vents 180, 184 and two end air vents 178, 182 all of which can be arranged to create an orthogonal arrangement (see FIG. 12), and a downward vent 124. The air distribution cover 103 is the largest of the components of the air distribution apparatus 101 and can comprise a lightweight material such as plastic. The cover barrier elements 204, 206 and the first pair of template barrier elements 170, 172 define supply air paths to one of the end air vents 178 or 182 and the two side air vents 180, 184 while the second pair of template barrier elements 174, 176 defines additional supply air paths to the other end air vent 182 or 178 and the two side air vents 180, 184.

[0049] Each of the return air areas 190, 192 can accommodate an air filter 212 (FIG. 14). The air distribution template 102 can include filter supports 214 (see FIG. 12) projecting into the return air area 190, 192. The filter supports 214 can define a space in which the air filter 212 can be slid through and a support surface for the installed air filter 212. As observable from FIG. 12, the air filter 212 is shaped to span across at least a portion of the return air area 190, 192 after it is inserted through a slot 216 (FIG. 13) on the air distribution cover 103. The air filter 212 (FIG. 14) is equipped with a grasping portion 218 while the air distribution cover 103 is equipped with a sunken portion 220 (see FIG. 18A) so that removal of the air filter 212 is facilitated by easy access to the grasping portion 218. The part of the air filter 212 near the grasping portion 218 can be curvilinear in shape to substantially conform to the curvature of the air distribution cover 103 when the air filter 212 is inserted. As shown in FIG. 14, the air filter 212 may also include a latch 222 configured to interlock with a portion of the air distribution cover 103 to hold the air filter 212 in place after insertion.

[0050] FIG. 15A and FIG. 15B show a grille 226 and a door 228 configured to define the downward vent 224. In FIG. 15B, the present embodiment of the door 228 is substantially shaped as one longitudinal half of an ellipse with a convex surface toward the exterior of the air distribution cover 103. The door 228 is configured to interact with the air distribution cover 103 to open and close the grille 226 which is substantially similar in shape to the door 228. The grille 226 can comprise part of a gutter 230 (see FIG. 15A) of the air distribution cover 103 along which the door 228 translates. The gutter 230 can include a slot 232 between two adjacent grille members. A T-shaped guide 238 of the door 228 can travel within the slot 232 thereby guiding the translating movement of the door 228 and determining the extent of the movement. The door 228 includes a biasing member 240 and a grasping element 242 which is a detachable part that engages the biasing member 240 from the other side of the grille 226. In this embodiment, the biasing member 240 is a cantilever beam and includes apertures 244 being engaged by the grasping element 242. Manipulation of the grasping element 242 moves the door 228 along the direction of the grille 226 as the door 228 is gradually opened. Because flange portions 246 of the door 228 keep the door 228 away from the grille 226, the biasing member 240 encourages the door 228 toward the grille 226. Biasing the door 228 toward the grille 226 results in sufficient friction such that the door 228 can maintain a position between a fully opened position and a fully closed position. The biasing member 240 includes a stop 248 which can abut against the air distribution cover 103 and define the fully closed position. The door 228 can conform to a curvature of the grille 226 in the fully closed position.

[0051] FIGS. 16A and 16B show an example side air vent 184. The other side air vent 180 can be a mirror image of the side air vent 184. Thus, it is understood that the structure and operation of both side air vents 180, 184 can be understood based on the following examples of the side air vent 184. As shown in FIGS. 16A and 16B, the side air vent 184 can include a pivoting cap 252 and a side opening 254 on the air distribution cover 103. The pivoting cap 252 can include a substantially curved surface 253 with a rectangular perimeter that conforms in shape to a curvature of the air distribution cover 103 in a fully closed position. The pivoting cap 252 may include bases 256 that can extend perpendicularly about the surface 253 and can include pivots 258 (one of two shown FIG. 16A) that snappingly mate with corresponding apertures 260 on walls 262 adjacent the side opening 254 thereby allowing the pivoting movement of the pivoting cap 252. The bases 256 can also include a latch 264 that engages the air distribution cover 103 at locations 261 defining discrete positions (see FIG. 16B) of the pivoting cap 252. The locations 261 can be formed by apertures, detents, openings, slots or the like. The air distribution cover 103 can also be provided with a sunken portion 266 to facilitate grasping of the pivoting cap 252. The pivoting cap 252 is opened through rotation away from the bottom wall 186 of the air distribution cover 103 and closed through rotation toward the bottom wall 186. The rotation of the pivoting cap 252 ranges from a fully closed position in which the pivoting movement is stopped by the sunken portion 266 and/or the edge of the side opening 254 and a fully opened position in which the pivoting movement is stopped by a shoulder 268 adjacent the side opening 254.

[0052] As shown in FIGS. 17A and 17B, the end air vent 182 can include a pivoting door 270, a grille 272 and a slot 274. The other end air vent 178 can be a mirror image of the end air vent 182. Thus, it is understood that the structure and operation of both end air vents 178, 182 can be appreciated based on the following descriptions of the end air vent 182. The pivoting door 270 may include a link 276 and an enlarged end 278 where the link 276 extends from the pivoting door 270 to an enlarged end 278. The pivoting door 270 can also include pivots 280 extending along a rotation axis and configured to snappingly mate with apertures (not shown) on walls 183 (see FIG. 11A) adjacent the end air vents 178, 182 to allow the pivoting movement of the pivoting door 270. The link 276 is configured to rotate about the rotation axis of the pivoting door 270 and passes through the slot 274 in the assembled state. As shown in FIG. 17B, the slot 274 can include enlarged portions 286, 287 that define discrete positions of the pivoting door 270 formed by allowing the enlarged end 278 to achieve stable conditions. The discrete positions of the pivoting door 270 are further defined by the fact that the length of the link 276 is configured so that the enlarged end 278 elastically engages the slot 274 to encourage seating of the enlarged end 278 in the enlarged portion 286, 287 corresponding to the discrete positions. In the present embodiment of the end air vent 178, 182, a fully closed position of the pivoting door 270 is reached when the link 276 is fully rotated toward the bottom wall 186 while a fully opened position of the pivoting door 270 is reached when the link 276 is fully rotated away from the bottom wall 186.

[0053] This example embodiment of the air distribution apparatus 101 is assembled in the following manner as shown in FIG. 2. The upper end of the supply air duct 106 is secured to the air conditioner 107 via upper bracket with double stick tape or snaps. The electric box 154 is mounted on the air distribution template 102. The brackets 104, 105 are assembled onto the air distribution template 102. The brackets may be secured with respect to the air conditioning port and then the lower end of the supply air duct 106 can be fastened to the air distribution template 102 using the ring 150. Excess supply air duct 106 is removed. The air vent components are assembled on the air distribution cover 103, and the air distribution cover 103 is mounted onto the air distribution template 102. The air filters 212 can be inserted after the air distribution cover 103 is mounted on the air distribution template 102. The air distribution template 102 and the air distribution cover 103 have apertures 288 (see FIG. 11A) that are axially aligned after mounting the air distribution cover 103 onto the air distribution template 102 so that the two can be secured together using fasteners such as screws. The template barrier elements 170, 172, 174, 176 may include latches (not shown) near the end air vents 178, 182 that engage projections 185 on the walls 183 (see FIG. 11A) to secure the air distribution template 102 to the air distribution cover 103 without fasteners.

[0054] After assembly is completed, the air distribution apparatus 101 forms a device that is able to channel air to and from an air conditioner 107. In one example, the air distribution apparatus can channel air in one or more of four laterally orthogonal directions and a downward direction while creating only a slight protrusion in the ceiling. The air distribution apparatus 101 has a low profile because the air distribution template 102 is substantially submerged within the air distribution cover 103 while at the same time securing the bracket structure. In further examples, the low profile can be enhanced by allowing the body portion 110 of the brackets 104, 105 to at least partially extend into the air conditioning port 108 in the ceiling surface 111. In still further examples, as described above, the electric box 154 can be secured to the air distribution template 102 to contribute to the low profile of the air distribution apparatus 101. As shown in FIG. 3C, the air distribution template 102 allows the overall thickness T₁ of the air distribution apparatus 101 to be reduced to less than the sum of the thickness T₂ of the bracket structure and the thickness T₃ of the air distribution cover 103. The thickness T₃ of the air conditioning cover 103 represents the thickness adjacent the outer perimeter. In further examples the thickness T₃ can extend over a substantial portion of the cover. Certain portions of the cover 103 may be greater in thickness than T₃. For example, the portion of the cover 103 including the gutter 230 (see FIG. 15A) can extend further than the thickness T₃ of the remaining portions of the air conditioning cover 103.
