Name of Applicant: Actual Inventor: Address for service in Australia: Invention Title: FLETCHER ALUMINIUM LIMITED Sean Francis O'Sullivan A J PARK, Level 11, 60 Marcus Clarke Street, Canberra ACT 2601 Joinery Drainage The following statement is a full description of this invention, including the best method of performing it known to me/us -2- The present invention relates to window and door framing.

Many forms of extruded member are known for the use in the provision of frames for windows and doors.

The present invention relates to such extrusions, to assemblies or structures using such extrusions and to related procedures and methods which will have the effect of draining, to the outside of a structure into which the joinery is installed, waters that might otherwise pool.

It is an object of the present invention to provide for joinery drainage through the provision of holes (milled, drilled, punched, cut, eroded, etc.) (ie; "machined") into the extruded sill, head, jamb or the equivalent which will allow drainage of water that might otherwise pool and a pathway for such water to the exterior (whether laterally or into a vertical member of the frame).

Preferably the provision is such that there can be inserted, at least in the vicinity *of any such holes, a baffle or other separating member which will have the effect of S"minimising interference of two flows of different drainage waters to the outlet or outlets *.and/or which might minimise to some extent blowback from the exterior.

In a first aspect the invention is a jamb, sill, head or the like horizontally extending assembly of or for a frame, said frame to be that of or for a door or window, said jamb, sill or head (hereafter "apparatus") comprising or including ;"an extruded form (albeit with some post extrusion machining) having an extruded hollow section and which is adapted to extend with its extrusion axis substantially S* horizontal to define, with respect to the intended eventual plan of the door or window, an inward water collection surface and, more outwardly from said inward water collection o o 000,surface, another water collection surface (hereafter "more outward water collection surface"), and wherein there is provided a "machined" inlet into the hollow section of the extruded form from each said water collection surface to allow from the respective surface water drainage ingress into said hollow section, and wherein there is provided at least one outlet from said hollow section (whether endwise or laterally, or both) to allow water draining thereinto to egress under gravity, and wherein means is provided within or as part of said hollow section to physically separate as separate water flows that water draining through at least one machine opening from said inward water collection surface from that water draining in from said outward water collection surface until at least substantially adjacent said at least one outlet from said hollow section and/or baffle at least to some extent blow back of water in use through the hollow section and up through said inlet of said inward collection surface.

a Preferably said outlet(s) is (are) laterally of said extruded form.

Preferably said means to physically separate the flows includes a component capable of endwise insertion into the hollow form of the extrusion.

Preferably said inward water collection surface is an interior condensation water collection channel.

Preferably said more outwardly water collection surface is a glazing cavity.

Preferably the arrangement is substantially as hereinbefore described with at least some reference to Figures 3B or 4B of the accompanying drawings.

In another aspect the invention is a composite structure forming part of a frame for a door and/or window, said structure comprising or including, a first component being an extrusion to form a horizontally extending interior condensation water collection channel and, more outwardly therefrom, a glazing cavity, the extrusion having an extruded hollow section and at least one machined opening from each of said interior condensation water collection channel and said glazing cavity into said hollow section and having at least one machined drainage outlet from said hollow section, and at least one other component engaged within said hollow section thereby to provide a physical barrier to drainage flow mixing until at least adjacent said at least one drainage opening and /or to baffle between said openings of said channel and cavity and to some extent baffle to said opening of said channel.

Preferably said means is an extrusion and such extrusion provides said flow separation down to adjacent said egress outlet(s).

Preferably said at least one other component is or are of a moulded or extruded nature.

In still another aspect the invention is a machined extrusion, whether part of a frame or not but for use as part of a frame for a door and/or window, having the flow separation characteristics substantially as hereinbefore described with reference to the accompanying drawings.

In yet another aspect the invention is a machined extrusion suitable for use as a horizontally extending component of a door frame or window frame, or a hybrid of both, said extrusion having a cross-section defining a hollow and closed section, and two exterior channels both to open upwardly in use, one channel to provide a glazing channel with provision for seal location and one channel to provide an inside condensation water collection channel, (and optionally means to engage a reveal), and -4- (ii) at least one machined opening into said hollow and closed section from each said channel, at least one machined drainage water egress opening from said hollow and closed section for drainage therefrom and machined ends suitable for said frame fabrication, and wherein said hollow sand closed section allows the insertion and location of a water flow separator of any appropriate form from an end or ends of said extrusionto separate in the hollow section any drainage flows in use from said channels at least substantially to said drainage water egress opening(s) and which as a baffle also will reduce blowback from the exterior.

In another aspect the invention is a window frame including apparatus of the present invention.

In another aspect the invention a door frame including apparatus of the present invention.

In still another aspect the invention is a method of reducing water blowback through a window and/or door frame which involves the operative use of apparatus of the present invention.

In another aspect the present invention consists in a frame for a door and/or :i window (or at least the jamb, sill or head thereof) which includes a horizontally extending extruded hollow section having an inward water collection surface (eg; an ""interior condensation water collection channel) and, more outwardly therefrom, another ""water collection surface (eg; glazing cavity), the arrangement being characterised in that there is provided a "machined" outlet into the hollow extrusion from each said surface and ***means is provided to separate the gravity flows of water through such machined openings :*from each said surface at least substantially to an outlet or outlets to the exterior from said .i hollow section.

Preferably said means to separate the flows includes a length of material or separating partition section or a moulded form or other structure capable of endwise insertion into the hollow form of the extrusion.

Preferably the arrangement is substantially as hereinafter described with at least some reference to Figures 3B or 4B of the accompanying drawings.

In still a further aspect the present invention consists in a window frame including the feature previously described as a characterising feature.

In another aspect the present invention consists in a door frame having such a characterising feature.

In still a further aspect the present invention consists in a method of minimising flow interference from window and/or door framing which involves the operative use of features or apparatus of the present invention.

Two preferred forms of the present invention will now be described with reference to the accompanying drawings in which; Figure 1A is an end view of a door frame extrusion, Figure 1B is an end view of a preferred door frame extrusion, Figure 2A shows one form of a window frame extrusion, Figure 2B shows a preferred window frame extrusion, Figure 3A is the door frame extrusion of Figure 1A (approximately double actual size) showing two water flow pathways and provided by an appropriate machining of openings (not shown) into the hollow form of the extrusion from each of two water collection surfaces and from a zone downwardly therefrom to the exterior, Figure 3B shows a similar arrangement to that shown in Figure 3A, however the door frame extrusion in this instance being of the preferred kind as shown in Figure 1B, Figure 4A is a corresponding drawing to that of Figure 3A for the window frame extrusion of Figure 2A, this time showing two downward flows to a lower exterior outlet or outlets, Figure 4B is likewise a corresponding drawing to that of Figure 3B for the window frame extrusion of Figure 2B, there being two downward flows to a lower exterior outlet or outlets, and Figure 5A is an extrusion capable of being used in conjunction with the extrusion of Figure 2A to provide a full frame, the extrusion of Figure 2A preferably being used for the jam and heads only where it is not considered appropriate to have the hollow section fully around the perimeter, ~Figure 5B shows an extrusion similar to that shown in Figure 5A, the extrusion capable of being used in conjunction with the extrusion of Figure 2B to provide a full frame, and Figure 6 shows an end view of a preferred sliding window frame extrusion that accords with the present invention, and Figure 7 shows yet another preferred sliding window frame extrusion, in this instance the extrusion carrying provisions for engaging a glazing bead of the type shown in Figures 4A and 4B.

In the preferred form the extrusion (eg; of aluminium) can be square or mitre cut at the ends and drilled or milled to provide all said inlets/outlets laterally of the extrusion.

In other less preferred forms said outlet can be a running outlet to the ends of the extrusion and from thence out of the frame.

In the preferred form of the present invention, in the case of a door frame, the component shown in Figure 3B provides a water flow path A provided by a machined upper opening or openings down to a lower opening or openings from the hollow section -6to the exterior of the structure into which the frame is fitted. Likewise the condensation channel is machined to provide an opening into the hollow form for a flow path B which preferably exits out the same or different openings to the exterior.

Interposed between the flow paths A and B in the vicinity of the machined openings (so as to achieve an actual separation and preferably to provide a baffle which serves a blow back restriction function (at least into the condensation channel)) there is provided a moulded, extruded or otherwise formed partitioning member C (eg; of aluminium or a plastics material) shown in broken outline that can be of any appropriate configuration, length, etc.

Preferably said member C is positioned and engaged so as to be rattle free in use in windy conditions.

Similarly, in relation to a window frame of Figure 4B (which may have all sides formed with the section shown or may be a composite of the extrusions of Figures 2B and 5B), preferably the sill and head is provided with machined openings to allow the flow paths D (from the bead area for the glazing) and E (from the condensation channel) out the exterior. In this case a partitioning member or baffle of a similar form to that previously described in relation to the door is provided. This is designated by the broken :i line F. Again it can be of any appropriate configuration that positioning stablely in that zone (whether perpendicular and/or parallel to extrusion length or otherwise).

Preferably the sill, jamb or head extrusions of the hollow form depicted are cut square or mitred as might be appropriate for the particular form and, if appropriate, is keyed into related components and/or otherwise attached thereto, eg; by screwing, by crimping, etc. Such interconnection aspects preferably do not interfere with the positioning of the water flow separation members C and F referred to.

Persons skilled in the art will appreciate how the present invention provides for a lack of interference of one flow path with another until such time as the waters are pooled at the outlet from the extrusion, if indeed they ever encounter each other.
