DETAILED DESCRIPTION OF THE INVENTION

Air Communicating Trim Moulding

[0050] Referring first to FIGS. 1 and 2, which shows an Air Communicating Trim Moulding 100 deployed onto a prepared door frame 300 and an Air Communicating Adjustable Width Trim Moulding 400 deployed onto prepared door frame 300 and a width adjustable trim molding as in FIG. 18, 19 or 20 deployed as a baseboard 601.

[0051] The Air Communicating Trim Moulding 100 could also be deployed around an internal window as for example in office spaces where it is desirable to increase passive air exchange. Wood frame construction of window openings is analogous to as depicted prepared door frame 300 with the addition of a window lower horizontal portion not found in doors.

[0052] Prepared door frame 300 in normal construction would include a rough opening frame shown as 170, several shims or spacers 172, and interior door jamb 174. The rough opening frame 170 is always roughed in substantially bigger than the finished door jamb 174 to accommodate adjustability of the door jamb 174 in the lateral direction 162, transverse direction 160, and possibly also in the longitudinal direction 118. Positioning of the door jamb 174 is accomplished using shims or spacers 172 such that once the door jamb is in the desired position and plumb, screws are normally driven through the door jamb 174, through the shims 172, and into the rough opening frame 170. The rough opening frame is normally constructed of 24 and/or 26 dimensional lumber and the door jamb is normally , , , or 1 thick material.

[0053] The lateral width of the door jamb is selected such that the transverse edge 184 of door jamb 174 aligns along the same plane as wall surface 178 as shown in FIG. 2. This construction results in an air gap 302 which is defined as the space in between the rough opening frame 170 and the door jamb 174. In practice, this space is anywhere from inch to 1.25 inch wide, depending upon the tolerance between the rough opening frame 170 and the door jamb 174 and the thickness of the materials. The vertical portion of the rough opening frame 170 is often referred to as jack studs 350 whereas the horizontal portion of the rough opening frame 170 is often referred to as the header 354. Prepared door frame 300 is finished off by attaching wall board 176 to the rough frame abutting stud edge 352 of jack stud 350 as shown in FIGS. 2 and 5. In this manner, transverse edge 184 of door jamb 174 lies in the same plane as wall surface 178.

[0054] It is notable that Air Communicating Trim Moulding 100 and Air Communicating Adjustable Width Trim Moulding 400 are capable of being installed as a casing, or more specifically as a door casing as shown as 200, and/or as a baseboard 601.

[0055] In FIG. 1 the vertical direction and the longitudinal direction are denoted 118 for the vertically oriented portions and the horizontal direction is denoted the transverse direction 160.

[0056] FIG. 2 which is a cross section taken along section line 2-2 in FIG. 1, and shows in cross section an Air Communicating Trim Moulding 100 which in this case is the door casing 200 deployed onto a prepared door frame 300 which in this diagram includes door jamb 174, jack stud 350, and wall boards 176 which have a wall surface 178.

[0057] Referring additionally to FIGS. 3, 4, 6, 12, and 13, all of which show Air Communicating Trim Moulding 100. Referring first to isometric FIGS. 12 and 13 which show the top side 104 in FIG. 12 in and the bottom side 102 in FIG. 13. Air Communicating Trim Moulding 100 includes left edge 106, right edge 108, top side 104, bottom side 102, and width 103. Trim molding is generally sold in preselected longitudinal lengths along the longitudinal direction 118 and often are sold in random lengths. The bottom side 102 of Air Communicating Trim Moulding 100 defines air passageway 110 which allows movement of air along the bottom side 102 of Air Communicating Trim Moulding 100 as shown. Protrusions 123 having a contact surface 120 stand-off intermediate surface 119 from bottom surface 117 thereby creating an edge opening 116. The edge openings 116 allow for communication of air along air passageway 110 since intermediate surface 119 is spaced from bottom surface 117.

[0058] Edge openings 116 are air communicating openings defined in at least one edge 106, 108 of the trim molding 100, such that air is communicated into or out of the air passageways through the edge openings to or from the exterior air 113. The edge openings 116 allow exterior air 113 to be communicated to the air passageways 110 which in turn communicate air 112 to the air gap 302. Exterior air 113 is air that is not within air passageways 110, air gap 302 and edge openings 116 or within the continuous air conduit 312.

[0059] Air Communicating Trim Moulding 100 includes top surface 121, bottom surface 117 and spaced there between an intermediate surface 119. Air passageway 110 is defined as the space between the intermediate surface 119 and the bottom surface 117. Contact surfaces 120 are preferably coextensive with bottom surface 117 and are preferably adapted to maintain space between the bottom surface 117 and the intermediate surface 119 thereby providing flow of air 112 along air passageway 110.

[0060] Preferably bottom surface 117 is a planar surface however there may be applications where this in not the case. Similarly, and preferably intermediate surface 119 is a planar surface extending parallel to and spaced from the bottom surface 117, however this is not necessarily always the case. For example intermediate surface 119 may in fact be multiple stepped surfaces at different spacings between top surface 121 and bottom surface 117.

[0061] FIG. 3 shows bottom side 102, air 112 and air flow 111 designated by lines and arrows which schematically depict the movement of air 112 through air passageway 110. The Air Communicating Trim Moulding 100 is supported on contact surfaces 120. Additionally in FIG. 4, one can see the edge openings 116 which are also visible in FIGS. 12 and 13. In practice there may be edge openings 116 on only one edge of the Air Communicating Trim Moulding 100. For example, the left edge 106 may abut up against a nearby wall thereby allowing for airflow only through right edge 108 in which case it may be preferable to have edge openings 116 on only one edge.

[0062] Referring now to FIG. 6, Air Communicating Trim Moulding 100 is shown in schematic fashion with air passageway 110 shown as a gap between the contact surface 120 and the intermediate surface 119.

[0063] Referring now to FIG. 2, the contact surface 120 proximate the right edge 106 abuts against the transverse edge 184 of the door jamb 174. The contact surface 120 proximate the right edge 108 of the Air Communicating Trim Moulding 100 abuts against the wall surface 178 of wall board 176. Preferably the transverse edge 184 and the wall surface 178 are parallel and co-extensive and therefore the Air Communicating Trim Moulding 100 should lay flat with the contact surfaces 120 making abutting contact as in the drawing.

[0064] Referring to FIG. 2, the reader will note that there are depicted in cross section two Air Communicating Trim Mouldings 100, one located on the exterior side 306 of the prepared door frame 300 and another located on the interior side 304 of the prepared door frame 300. In practice, door casings are usually installed in this manner in current building construction methods.

[0065] Air 112 is communicated from the exterior side 306 through edge openings 116 and through air passageway 110 to provide airflow 111 on through air gap 302 which is the gap between the jack stud 350 and the door jamb 174 and air 112 continues to flow through air passageway 110 on the interior side 304 out through the edge opening 116 into the interior side of the prepared door frame 300. In this way, one can communicate air back and forth from the exterior side 306 to the interior side 304 of a door without opening the door or moving the door and also from the interior side 304 to the exterior side 306 of a door without opening or closing the door thereby equalizing air pressure and promoting air movement between an exterior side 306 and interior side 304 of a prepared door frame 300. The arrows in FIG. 2 show the movement of airflow 111 which produce a continuous air conduit 312 between the exterior side 306 and the interior side 304.

[0066] The Air Communicating Trim Moulding 100 depicted in FIG. 1 is a door casing 200 which in addition to normal door casings, not only provides for covering of the rough opening of prepared door frame 300, but also provides for a continuous air conduit 312 between the interior side 304 and the exterior side 306, the continuous air conduit 312 includes an air passageway 110 along the trim moldings on both the interior and exterior sides and along air gap 302. The trim molding in this example is door casing 200. This could also be applied to window casings, casings in general and baseboards.

[0067] Referring to FIG. 13, the air passageway 110 and the edge openings 116 can take on any number of shapes and provide for communication of air. The reader will note that the contact surfaces 120 and edge openings 116 can take on many different locations, shapes and sizes depending upon the amount of airflow 111 and the desired look that the manufacturer requires for a particular application.

Air Communicating Adjustable Width Trim Moulding

[0068] Referring now to FIGS. 5, 7, 8, 9, 10, 11, 14, 15, 16, and 17, which all depict Air Communicating Adjustable Width Trim Moulding 400. Note that the air communication that is provided for by Air Communicating Adjustable Width Trim Moulding 400 in analogous fashion to the air communication as shown and depicted and described above for Air Communicating Trim Moulding 100. The reader will note, from the diagrams, the analogous movement of air 112 provided for by Air Communicating Adjustable Width Trim Moulding 400.

[0069] Referring first to FIGS. 14 and 15, Air Communicating Adjustable Width Trim Moulding 400 includes a longitudinal left portion 402, longitudinal right portion 404 each extends along longitudinal length 405. Air Communicating Adjustable Width Trim Moulding 400 is usually supplied in random longitudinal lengths 405. Left portion 402 and right portion 404 are connected together via a connecting element 406 which is preferably a planer element 422 which is slidably received into a left groove 432 in left portion 402 and into right groove 435 of right portion 404 such that by selectively inserting the connecting element 406 into left groove 432 and right groove 435, one can select the overall width 426 of Air Communicating Adjustable Width Trim Moulding 400. Air Communicating Adjustable Width Trim Molding 400 also includes left edge 412, right edge 414, edge openings 420, top side 410, and bottom side 408 which has air passageways 450 and contact surfaces 421. Air Communicating Adjustable Width Trim Moulding 400 includes overall width 426 and transverse direction 405.

[0070] Protrusions 427, having a contact surface 421, stand-off intermediate surface 419 and connecting element bottom surface 423 from bottom surface 417 thereby creating an edge opening 420. The edge openings 420 allow for communication of air along air passageway 450 since intermediate surface 419 is spaced from bottom surface 417 and connecting element surface 423.

[0071] Air Communicating Adjustable Width Trim Moulding 400 includes top surface 425, bottom surface 417 and spaced there between an intermediate surface 419 and connecting element bottom surface 423. Air passageway 450 is defined as the space between the intermediate surface 419 and connecting element bottom surface 423 and the bottom surface 417. Contact surfaces 421 are preferably coextensive with bottom surface 417 and are preferably adapted to maintain space between the bottom surface 417 the intermediate surface 419 and connecting element bottom surface 423 thereby providing flow of air 112 along air passageway 450.

[0072] Preferably bottom surface 417 is a planar surface however there may be applications where this in not the case. For example bottom surface 417 may be a landing point or an undulating surface. Similarly, and preferably intermediate surface 419 and connecting element bottom surface 423 is preferably a planar surface extending parallel to and spaced from the bottom surface 417, however it is not necessarily always the case that the surfaces are planar.

[0073] Referring now to FIGS. 7 and 8, the planer element 422 is shown almost completely inserted into left groove 432 and right groove 435 in FIG. 7 such that the left portion 402 and the right portion 404 make contact which therefore defines the minimum width 426 which the Air Communicating Adjustable Width Trim Moulding 400 can provide. The grooves have a transverse depth 440. The drawing also shows air passageways 450, connecting element 406 and edge openings 420.

[0074] FIG. 8 shows in cross section, as in FIG. 7, the Air Communicating Adjustable Width Trim Moulding 400 where in the planer element 422 is minimally inserted into left groove 432 of left portion 402 and minimally inserted into right groove 435 of right portion 404, thereby providing for a practical maximum width for Air Communicating Adjustable Width Trim Moulding 400. The drawing also shows bottom surface 417 and intermediate surface 419. The reader will note that it is not necessary to have two grooves 432, 435 as depicted. One could have only one groove as shown in FIG. 20. Alternately the connecting element may be rigidly fastened in place in one of the portions 402, or 404 therefore allowing adjustability with the spacing of the other portion. Additionally, the size of the left and right portions 402, 404 and specifically the widths of the portions may be different from each other. In practice it seems fastening one side of the connecting element 406 or having a rigid tongue as shown in FIG. 20 is preferable.

[0075] FIGS. 9 and 17 shows the placement of an ornamental moulding 490 in the gap between the left portion 402 and the right portion 404 which is placed onto top surface 425 of planer element 422. The ornamental moulding 490 is normally sized to take up the gap between the left portion 402 and the right portion 404 however this is due to aesthetic considerations.

[0076] Referring to FIG. 5 which shows Air Communicating Adjustable Width Trim Moulding 400 deployed onto a prepared door frame 300 in an installed position 418. The air communication takes place in analogous fashion as in FIG. 2 for the Air Communicating Trim Moulding 100. Air Communicating Adjustable Width Trim Moulding 400 has the following components: jack stud 350, wall board 176, door jamb 174, air gap 302, wall surface 178 having a transverse direction 160 and a lateral direction 162 wherein the major difference between that shown in FIG. 2 and FIG. 5 is that rather than Air Communicating Trim Mouldings 100 installed on the interior side 304 and exterior side 306, we have Air Communicating Adjustable Width Trim Mouldings 400 installed on the interior side 304 and the exterior side 306 which provides for the communication of air 112 through the air passageway 450 which provides for a continuous air conduit 312 allowing the exchange of air between the exterior side 306 and interior side 304 analogously as that shown in FIG. 2. In this case, Air Communicating Adjustable Width Trim Moulding 400 includes a left portion 402, a connecting element 406, and a right portion 404 for adjustability of the width 426. Contact surface 421 abuts with transverse edge 184 as shown in FIG. 5, thereby providing for air communications through edge openings 420 of Air Communicating Adjustable Width Trim Moulding 400.

[0077] The width adjustment allows one to accommodate a variety of widths of casings that may be required to cover up the rough opening. In some instances, if an existing casing is removed from the door opening the replacement is usually width matched which can be easily accomplished using the Air Communicating Adjustable Width Trim Moulding 400.

[0078] Shown in FIG. 16 is a door casing 700 having an ornamental surface 702 and a bottom surface 704 which lies adjacent and abuts to top side 410 of Air Communicating Adjustable Width Trim Moulding 400. In this way by having width adjustability one can adjust the width to match any other ornamental door casing 700 one wishes to place on top of a flat or nearly flat surface of the top side 410 of Air Communicating Adjustable Width Trim Moulding 400.

Width Adjustable Casing and Baseboard

[0079] Referring to FIGS. 18 and 19 Width adjustable trim 600 is shown in a simple rectangular geometry. Width adjustable trim 600 includes left portion 602, right portion 604, top side 606, bottom side 608, connecting element 610, left groove 612, right groove 614, and has a width 618. Grooves 612 and 614 have a transverse depth 630 and connecting element 610 is preferably a planar element 620. Width adjustable trim 600 has a transverse direction 632 and a longitudinal direction not shown which is normal to the page. Width adjustable trim 600 is analogous to Air Communicating Adjustable Width Trim Moulding 400 in terms of the width adjustability however Width adjustable trim 600 does not have the air communication function. The reader will note that it is preferable to have planar element 620 to be rigidly attached by glueing for example to one of the portions 602 or 604 and have the adjustability function limited to only one portion. Another example of this is depicted in FIG. 20 wherein the connecting element 610 is a rigidly attached tongue to a left portion of the trim. In this case the tongue is integrally part of the left portion

[0080] Referring to FIG. 20 Width adjustable trim 800 is shown in a simple rectangular geometry. Width adjustable trim 800 includes left portion 802, right portion 804, tongue 806, and groove 808. In this case tongue 806 is integrally part of one of the portions in this example the left portion 802 and the groove is only insertable the groove 808 in other portion in this example the right portion 804. Adjustability in transverse direction 632 is analogous to the previous examples.

[0081] FIG. 1 depicts baseboard 601 which is a width adjustable trim molding 600 as shown in FIGS. 18 and 19 or it may also be a width adjustable trim molding 800 as shown in FIG. 20.

Air Communicating Trim Moulding Stand-Off Strip and Spacer Block Kit

[0082] Referring to FIGS. 21, 22, 23, and 24 a stand-off strip shown generally as 500 may include long spacer blocks 502, short spacer blocks 504, mounted onto a connecting tape 506 which may have adhesive on one side to adhesively attach to intermediate surface 510 of a trim molding board 520 as shown in FIG. 22. Each block 502 and 504 have a bottom surface 508 spaced from an intermediate surface 510 thereby creating an air passageway 518 through edge openings 512 along left edge 514. Right edge 516 of stand-off trim molding 501 may as shown in FIG. 23 or may not as shown in FIG. 22 include a stand-off strip.

[0083] double stand-off trim molding 503 will provide communication of air through edge openings 512 of both the left edge 514 and the right edge 516 whereas stand-off trim molding 501 only provides for air entry into air passageway 518 along left edge 514.
