Patents Act 1990 COMPLETE SPECIFICATION STANDARD PATENT Applicant(s): DOWELL AUSTRALIA LIMITED A.C.N. 004 437 898 Invention Title: REVEAL FOR WINDOW OR DOOR ASSEMBLY The following statement is a full description of this invention, including the best method of performing it known to me/us: I I REVEAL FOR WINDOW OR DOOR ASSEMBLY Field of the Invention This invention relates to a reveal for a window or door assembly and relates particularly, but not exclusively, to such for aluminium extruded window or door assemblies.

Description of Prior Art Hitherto, it has been common to provide an extruded window or door frame and to attach a wooden reveal to the window or door frame so that it extends inwardly of the building to which it is attached. Recently, quality woods for finishing surfaces have become quite expensive.

iii It is considered that it is now cost effective to produce the reveal from extruded section and particularly, although not exclusively, from extruded aluminium.

""Object and Statement of Invention The present invention is directed towards a reveal of that nature and attempts to overcome the cost problem associated with the use of a total wooden reveal for such windows or doors.

S" According to a first broad aspect of the present Sginvention there may be provided an extruded window frame or door frame assembly having an internal reveal, said assembly including an extruded frame to carry said window or door, and a reveal frame, said reveal frame including at least two extruded reveal frame parts interconnected to said extruded frame, one reveal frame part interconnected with one side or top of said extruded frame and the other reveal frame part interconnected with an opposite substantially parallel extending side or bottom of said extruded frame, the interconnections being by a respective a 3 flange of each of said reveal frame parts locating behind a respective corresponding flange of said extruded frame sides or top or bottom, to inhibit against removal of said reveal frame from said extruded frame in a direction transverse to the plane of the window or door to be carried by said extruded frame.

Most preferably there are two further interconnecting reveal frame parts extending between adjacent ends of said two reveal frame parts and connected therewith.

It is further preferred that all four reveal frame parts are of the same transverse cross-section and that said two further interconnecting reveal frame parts each have a respective flange thereof locating behind a respective corresponding flange of said extruded frame S.sides or top or bottom.

In accordance with a further aspect of the present invention there may be provided an extruded reveal frame part for an extruded window or door frame, said reveal frame part having a surface which will be exposed as the reveal face and an edge surface for butting with the extruded frame of said window said reveal frame part having a flange extending from behind a reveal face and past an *edge surface, to permit location of said flange behind a flange of said extruded frame to inhibit against removal from said door or window frame in a direction transverse to the plane of a window or door to be carried by said frame.

Most preferably, said extruded reveal part has surfaces at the rear of said reveal face which can be used to effect mounting of said reveal and said frame to a building.

It is particularly preferred that said surfaces comprise two opposed faces which can be engaged by a IIR il~l I 3A mounting bracket.

It is further particularly preferred that a reveal frame part as claimed in claim 9, or claim provided with either screw flute channels or flange surfaces which will permit two such reveals, which are brought together at their ends in butting, mutually perpendicular alignment, to be interconnected with screws or stakes engaging with said screw flute channels or flange surfaces.

In another embodiment, the mounting can be effected by having the reveal face provided with a recessed *e

I

I~ 4 channel, and fastening means can be passed into said channel and through said reveal part and an infill cover can then subsequently be fitted into the channel to cover the fastening means.

Detailed Description of Preferred Embodiment The present invention is applicable to window or door frame assemblies and the description which follows will be in relation to a window assembly. It should be appreciated that the concepts expounded apply also to doors.

Referring now to Figures 1 and IA there is shown an ext:ruded window frame 1. The window frame 1 may have a further frame carried thereby which supports a pane of glass. Alternatively, a pane of glass may be suitably glazed into the window frame 1. The window frame 1 is held 15 relative to a window opening 3 provided in the external covering of the building. In this example, the external covering is of bricks and mortar 5. The building has an internal stud frame wall and one such stud 7 is shown. The stud 7 is aligned relative to the window opening 3. A noggin 9 extends between a pair of studs 7 on each side of the window opening 3 at the sill level. A similar noggin 9 may extend between the studs 7 at the head level.

The window frame 1 can be of known configuration and of known extrusions.

e A reveal frame 11 is provided on the internal part of the assembly. Thus, the reveal frame 11 can be referred to as an internal reveal. The reveal frame 11 is S"fabricated from an extrusion which may, typically, be of suitable metal such as aluminium or it may comprise a suitable plastics material. Typically, an aluminium extrusion is preferred.

Figure 1A shows plaster board 13 attached to the studs 7 and noggin 9 and an architrave 15, such as of wood, attached to the inside edge of the reveal relative to the building.

Referring now to Figure 2 which is a rear isometric view of part of the assembly comprising the

~_C

6 window frame 1 and the reveal frame 11, it can be seen how the reveal frame 11 is interconnected with the window frame 1. The reveal frame 11 is formed from a reveal part 17 which has a reveal face 19 which is intended to be the exposed face of the reveal in the assembly. It also has an edge surface 21 for buttizg with an internal face 23 of the window frame 1. The reveal 11 also has a flange extending from behind the reveal face 19 past the edge surface 21, to permit location of the flange 25 behind a flange 27 of the window frame 1. As clearly shown in Figure 3, the edge surface 21 may have a protruding rib 29 so that the forward end of the rib 29 engages with the face 23 of the window frame. Figure 3 also clearly shows that the flange 25 of the reveal is generally transversely 15 extending relative to the reveal face 19 and is formed on a 31 which extends from the edge surface 21. Preferably, the flange 25 of the reveal is hook-shaped as shown, :although this is not absolutely essential. Thus, the hook is formed by a rib 33 extending mutually perpendicular to the flange 25. Thus, in use the flange 25 locates behind flange 27 of the window frame 1 and inhibits against removal of the reveal frame 11 in a direction transverse to the plane of a window carried by the window frame 1.

The flange 27 of the window frame 1 may be S 25 provided with an upstanding rib 35 so that the upstanding rib 35 can locate within the hook-shaped configuration of

CCC.

the flange 25 and rib 33. Thus, this will inhibit against S"considerable lateral in and out movement of the reveal frame 11 relative to the window frame 1 in a direction horizontally across the window opening.

In the embodiments shown in Figure 1, the reveal frame 11 is formed by identical section extrusions. The vertically extending extrusions are cut to a length to overlap the ends of the horizontally extending extrusions as shown by Figures 1 and 1A. Thus, in the embodiments shown in Figures 1 and 1A, and Figure 2, the reveal frame 11 is formed from four reveal parts. Thus, there are two IL II I 7 reveal parts extending along the upright sides of the window frame 1 and two further reveal parts extending along the top and bottom parts of the window frame 1.

Accordingly, it can be said that two such reveal frame parts the vertically extending parts are connected so that one of those parts is connected with a side of the window frame 1 and the other of the two reveal frame parts 4s connected with an opposite substantially parallel extending side of the window frame 1. Similarly, the horizontally extending reveal frame parts are connected so that one is an interconnected with a top of the extruded frame of the window frame 1 and the other is connected with the bottom of the extruded frame of the window frame 1 at the sill level again an opposite substantially parallel 15 extending part of the window frames.

The reveal frame parts are provided with surfaces 37 at the rear of the reveal face 19 which can be :used to effect mounting of the reveal part to the building.

Figures 2 and 3 clearly show that the surfaces 3' present two opposed faces which can be engaged by a mounting bracket 39. The mounting bracket 39 is formed from a sheet of strip metal such as galvanised sheet steel and provided with a body part 41 and a mounting leg 43. Typically the mounting bracket 39 is pre-formed to the shape shown in oo S 25 Figures 4, 5 and 6 with the mounting leg 43 being perpendicular to the body part 41. The body part 41 is provided with a pair of lugs 45 pressed from the sheet S"material of the body part 41. The lugs are displaced from the body part 41 by a distance approximately equal to the thickness of flanges 47 on which the surfaces 37 are provided. The inside edges are spaced slightly less than the spacing of the surfaces 37. The lugs 45 may be split as shown and bent downwardly as indicated. In use, the mounting bracket 39 can be located so that the lugs engage over the flanges 47 and effect twisting locking engagement with the surfaces 37 thereon. The split arrangement of the lugs 45 will permit biting engagement of 8 the lugs 45 into the metal of the flanges 47 when the mounting bracket 39 is twisted to engage over the flanges 47. In this arrangement, the mounting bracket 39 will be disposed transversely across the length of the reveal part.

This is shown clearly in Figure 2.

Figure 4 shows that a further mounting leg 43' may be provided on the body 41. This may be preformed so that it extends parallel with the mounting leg 43 or it may be left so that it extends parallel with the body 41 and bent by the installer as required. Figure 4 shows how it can be bent and swung to the required position. The distance between the mounting legs 43 and 43' will be arranged to correspond with the width of the stud 7 or the noggin 9. A nail or like fastening means can be passed 15 through the mounting legs 43 or 43' through a preformed opening 49.

By use of the mounting bracket 39 as shown, the reveal frame 11 can be fastened relative to the building so that the window frame 1 is correctly disposed relative to the window opening 3. In the assembled relationship of the reveal frame 11, the window frame 1 is carried by the .reveal 11 and sits in a required position in the window opening 3. Thus, the window frame 1 is not directly connected to the building or to the outer covering of the eeeJ•: building such as the bricks and mortar 5. Suitable silicon or other sealing material may be used to effect a weatheree tight seal if required.

S"The reveal frame 11 is held integral to itself by the use of screw flute channels 51 on the rear of the face 19. Thus, when the reveal parts are cut to length and then brought together in butting, mutually perpendicular alignment, they can be interconnected with screws passing through the face 19 of one of the reveal parts such as the vertically extending part and into the screw flutes 51 of the other part. The arrangement is such that the screws are carried behind the reveal face 19 and therefore cannot be seen following complete installation of the assembly to I I 9 a building.

The rear of the reveal face 19 is provided with a channel 53 at the side opposite to that of the flange The channel 53 is formed with opposed parallel sides 55 and 57. The channel 53 is provided to receive an insert 59 which may be of wood or of a high density polyethylene or other suitable material. The insert may be of a short lengt'r or it may extend the whole length of the reveal parts. The insert is typically provided with a corrugated surface which can matingly engage with a correspondincorrugated surface on the internal faces of the channel sides 55 and 57 so that it is a force-fit therein. The insert 59 is provided so that nails or other fastening means can penetrate the insert 59 so that the architrave 15 can be fixed thereto.

Figures 7 through 9 show various transverse cross-sectional views of the assembly shown in Figure IA.

These figures also show that a screw-tensioning device 61 is screwed through the flange 25 of the reveal part and wedged against an outer face of the window frame 1. The insertion of the screw tensioning means 61 in this way tends to spread the reveal part 17 relative to the window frame 1 and thus force the two sections into locking engagement. It also can inhibit against the rattling of S 25 the window frame 1 relative to the reveal frame. Thus, the screw tensioning device 61 can be inserted at desired locations around the assembly.

S" It should be observed from all of the previous figures and, in particular, Figure 3 that the flanges 47 are generally parallel and aligned co-planer. It is also observed that the outermost face of the flanges 47 on the outermost periphery of the reveal frame 11 only protrudes marginally outwardly past the edge face 63 (see Figure 8) of the window frame 1. Thus, whilst the window frame 1 is provided with a mounting flange 65 which extends outwardly past the outer face of the flanges 47, the mounting flange is provided with a score line 67 to enable the outer _1 L-111 10 portion of the mounting flange 65 to be removed by breaking therefrom. Thus, in this arrangement, when the outer portion of the mounting flange 65 is removed, the outermost width and height of the assembly comprising the window frame 1 and the reveal frame 11 corresponds substantially or marginally less to the window opening 3 or the space between opposed studs 7 or noggins 9. Thus, the assembly is suitable for retro-fitting into existing buildings by removal of the cuter portion of the flange It should be appreciated that in the embodiment previously disclosed, that the horizontally extending reveal frame parts 17 may be cut slightly longer than is necessary to effect tight engagement of the interconnecting flanges of the upright reveal part 17 with the 15 corresponding flanges of the upright frame parts of the window frame 1. Thus, slight adjustment can be effected in the positioning of the reveal frame 11 relative to the window frame 1 by moving the whole reveal frame 11 left or right as may be needed. Similarly, the horizontally extending reveal part 17 may be fitted with a similar lengthened arrangement so that up and down displacement may be effected. In this way, adjustment on site can be made to cope for slightly misplaced studs 7 or noggins 9. The screw tensioning devices 61 may be arranged to effect the S• 25 necessary transverse side to side or vertical up and down displacement as needed. Thus, appropriate insertion of the screw tensioning devices 61 can move the reveal frame 11 to 5some minor degree relative to the window frame 1.

Figure 10 shows the screw interconnected arrangement of the reveal part 17 at one corner.

Figure 11 shows a different arrangement of interconnection where a corner stake 69 can be force fitted 4nto appropriate channels in the reveal part 17. In this arrangement, a mitre cut can be provided at the butting ends of the reveal part 17.

Figure 12 shows a transverse cross-sectional view of a different arrangement of the reveal part 17 whereby 11 mounting of the reveal frame 11 can be way of screws or like fasteners. Here a channel 71 can be formed in the face 19 of the reveal part 17. The head of the screw 73 can be below the face 19 when the screw 73 is driven home.

An infill cover 75 can be force fitted into the channel 71 to cover the head of the screw 73. The cover 75 may be arranged to snap-lock into the channel 71 if desired.

Typically the cover 75 is of the same material as the reveal part 17 although it may be of some other material to provide contrasting decorative appearance if required.

In the embodiments described it can be seen that the cut of the reveal parts 17 is effected by a straight cut and that check-out cuts and the like are not needed to effect a neat engagement of the abutting frame part 17.

15 The whole assembly can be uniformly painted or coated such as by powder coating to give a durable surface Sto the assembly.

Modifications may be made to the invention as ~would be apparent to persons skilled in the aluminium and/or window or door arts. For example, the window frame 1 may be fitted with an architrave in accordance with the 4** S'disclosure in our Australian Patent Specification No 590479. A similar internal architrave 15 may be provided oooe in accordance with the disclosures in that aforementioned S 25 Australian patent specification.

In another modification only two reveal parts o oo with the flanges 25 for connecting behind flanges 23 of the window frame 1 may be used. In this case they may be fitted to the two vertically extending jamb parts of the window frame 1 or to the two top and bottom horizontally extending parts of the window frame i. These two reveal parts can then be interconnected with interconnecting parts at their ends to hold them in the required spaced apart position. For example, if the two vertically extending reveal parts 17 are fitted to the window frame i, the horizontal extending parts may be wood or other material parts, and these may be intended to be visible or non- 12 visible in the final assembly when fitted in a building.

These horizontally extending parts may not have flanges thereon corresponding to flanges 25 and thus may be used merely to hold the vertically extending reveal parts in position.

These and other modifications may be made without departing from the ambit of the invention, the nature of which is to be determined from the foregoing description.
