P:\wpdocsl\work\palm'ts lnftlingkoz\A FILTER FOR GUTTERING s mnmded al 3 Novwmba 2005 (2).doc-8/l 1/05 Q-1- Z A FILTER FOR GUTTERING Technical Field In The present invention relates to a novel filter for use with guttering.

Background of the Invention Buildings generally include guttering which allows for rain-water to be channelled away from the roof of the building. With some prior art guttering systems, leaves and other debris tends to accumulate in the open gutter and this may be problematic.

Firstly, accumulated leaves and debris in the gutter impedes the smooth flow of water through the gutter and may lead to water damage in the adjacent roof.

Secondly, the build up of dry leaves and other debris in the gutter provides a potentially flammable material which may be set alight by burning embers emanating from a bushfire.

One approach to solving these problems has involved mounting a permeable mesh over the guttering to prevent leaves and debris from entering the gutter, whilst at the same time, allowing for rain water to flow off the roof and freely into the gutter via the holes in the mesh. Unfortunately, the use of prior art meshs is not without its own problems.

For instance, prior art meshs are susceptible to an effect known as "sheeting" that is, the smooth flow of water through the holes in the mesh is inhibited due to a build-up of surface water tension within the holes of the mesh. At least to some extent, the occurrence of sheeting is attributable to the shape and dimensions of the holes in the mesh. Consequently, as water is unable to pass through the holes P:\wxpdcs\lw\wor k ptasetsUlraing akozA FILTER FOR GUITTERING as amded at 3 Nov-bW 2005 (2)doc-08/i 1/05 -2- Z into the gutter, the water will in many cases run-off back on to the roof leading to n water-damage particularly where the water is able to penetrate the internal roof structure via opening between the roof tiles, or otherwise.

Prior art meshs are typically manufactured from either metal material such as steel, or, a polymer material such as polypropylene or high density polyethylene.

n In the former case, metallic-based meshs are typically manufactured by way of 0louvring or welding techniques whilst in the latter case extrusion techniques are used to form the polymer-based meshs. In both cases, the respective techniques which are used to form the meshs tends to produce inconsistencies in shape and dimension both amongst different holes, as well as, within the internal structure of each hole from one side of the mesh to the other. As described above, this tends to exacerbate the occurrence of sheeting.

When fitting prior art meshs to cover a guttering, at least a portion of the mesh is typically secured beneath a row of tiles on the roof surface. However, the inherent properties of the prior art meshs results in air-gaps being formed between the mesh and the roof tiles and such air gaps leave the roof vulnerable to fire and/or water damage. In the case of polymer-based meshs, the material tends to have "memory" meaning that it will not readily stay contoured to the roof surface. The inherent rigidity of metallic-type meshs also makes it difficult for these types of meshs to be secured to the roof surface without giving rise to air-gaps.

Where the roof consists of a corrugated surface, leaves and debris will still tend to get caught in air gaps formed between the mesh and the corrugated surface due to the general difficulties in getting the mesh to be secured to closely along the corrugated contour.

In some cases, additional clamps and other securing devices are used to assist in holding the prior art meshs flush against the surface contour of the roof to reduce the occurrence of air gaps occurring. However the presence of such devices may P:\wpdocs\ll\workpatulsdrafning\kakozA FILTER FOR GUTTERING as amwded a 3 Novcmbe 2005 (2).doc-08/1 1/05 -3- 0 Z themselves give rise to air gaps.

Yet a further problem associated with the prior art is that, prior art meshs tends to vI be pre-fabricated into set forms which makes it less practical to fit the meshs to a variety of building structures to cover guttering. Moreover, additional time and 0labour is required to pre-form or pre-treat the set mesh modules as required, to vI/ suit the specific dimensions of a roof structure.

Summary of the Invention The present invention seeks to alleviate at least one of the above-described problems associated with the prior art.

In a first broad form, the present invention provides a filter for use in alleviating debris from entering a gutter, including: an expanded metal material having a substantially smooth first and second surfaces; a plurality of channels extending from the first surface to the second surface wherein: the plurality of channels include substantially uniform diamondshaped cross-sections; and (ii) the diamond-shape cross-section and dimensions of each channel at the first surface is substantially uniform with the diamond-shaped cross-section and dimensions of the channel at the second surface; and an engagement portion adapted for engaging with a roof surface adjacent to the gutter wherein, when engaged: the first surface is directed towards an opening of the gutter and the second surface is positioned to receive water flowing from the roof surface; and (ii) the engagement portion is able to be manually deformed in order P:\wpdc s\iw\work\pats\ draingLkakoz\A FILTER FOR GUTTERING s amwdcd at 3 Nov wb 2005 (2).dc-08/1 I/S -4- 0 Z to complement a contour of the roof surface so as to provide a t't substantially gap-less interface between the engagement portion and the roof surface substantially without pre-heating and/or pretreatment; whereby, when a mixture of water and debris flows on to the second 0surface, the debris is able to be substantially restrained from flowing into n the gutter opening, whilst the water is able to freely flow into the gutter opening via the plurality of channels.

Preferably, the diamond-shaped cross-section remains substantially constant along the length of each channel. Also preferably, the diamond-shape crosssection of each channel at the first surface may be substantially in alignment with the diamond-shaped cross-section of the channel at the second surface. Yet also preferably, the diamond-shaped cross-sections includes dimensions within the range approximately between 2 x 2 mm to 6 x 6 mm. More preferably, the dimensions of the diamond-shaped cross-sections includes 4 x 4 mm.

Preferably, present invention includes a powder coated material which may assist in alleviating corrosion and/or may provide a smoother surface upon which leaves and other debris may more easily slide off.

Preferably, the first and second surfaces are substantially smooth and planar.

Typically the planes of the first and second surfaces are substantially parallel to each other. Preferably the present invention includes a novel wire diameter range of approximately between 0.3 mm to 1 mm when formed from an expanded metal material before powder-coating. After powder coating, the wire diameter may increase by approximately 0.1 mm. More preferably, the wire diameter may be approximately 0.6 mm before powder-coating, and 0.7 mm after powder coating. Advantageously, the novel selection of this range of wire diameters has been found to provide a suitably flexible filter structure for ease of moulding to the contour of a roof surface whilst at the same time assists in giving rise to a P:\wpdocs31\wOlpatmk, ft,g\kkoz\A FILTER FOR OUrrERING a1 mdold W 3 Nov-nba 2005 (2).d-08/11/05 Z substantially smooth first and second surface of the filter which may alleviate the In effects of sheeting.

n Preferably, the engagement portion is able to be manually deformed to complement a contour of the roof surface substantially without pre-heating and/or pre-treatment. For instance, the engagement portion may readily deformed to the n specific roof-surface when the engagement portion is pinned down beneath the weight of a row of tiles. Advantageously, this may alleviate the occurrence of airgaps forming between the engagement portion of the filter and the roof surface. A further advantage which arises is that the installation of the filter is less labourintensive given that pre-treatment and/or preheating of the filter is not required. It should also be noted that by ensuring that the diamond-shaped cross-section of each channel at the first and second surfaces are substantially in straight alignment, this may also assist the present invention being more readily deformable.

Preferably, the present invention includes an aluminium material. More preferably the aluminium may include expanded aluminium. Advantageously, the use of aluminium may assist in the filter being more readily contoured to complement a surface characteristic of the roof without the need for pre-forming and/or preheating associated with the prior art due to the flexible properties of the expanded aluminium material. In contrast, prior art welded and/or louvred structures may tend to be relatively rigid and therefore less readily able to be contoured to complement a roof surface without pre-treatment and/or pre-heating.

Preferably, the present invention includes a gutter engagement portion which is adapted for securement with an outwardly-directed lip of the gutter. Also preferably, the present invention includes a means of securing the gutter engagement portion of the filter to the outwardly-directed lip of the gutter.

Typically this may include the use of a bracket, a clamp or the like. Typically a "right angle trim" may be used to perform this function. In particular, the P:\wpdocs\lw\workpatcnts\drafting\ktaozA FILTER FOR GUTTERING as amded a 3 November 2005 (2).doc-08/1 -6- 0 Z engagement portion may be secured to a corrugated roof surface using a saddle vI/ clamp which is held in place using screw and/or rivets.

uI Typically, the present invention may be conveniently provided in a relatively compact rolled-up fashion. The present invention may also be readily cut-to size Sfrom the roll so as to accommodate any number of disparate gutter configurations.

vI/ This is at least to some extent assisted by the particular choice of shape and dimensions and materials of the present invention.

In contrast, the relatively rigid nature of metallic prior art meshs and/or the difficulties in moulding non-metallic polymer meshs to the shape of the roof have meant that additional fastenings are often needed to secure the prior art into place and to try and mould the meshs to the roof contour. However, the use of fastenings, clamps and the like tend to exacerbate the occurrence of air gaps being formed.

Preferably, the present invention includes a non-louvred and/or a non-welded metallic material. Advantageously, this may avoid the occurrence of a non-smooth and/or irregular surface contour of the first and second surface which may exacerbate the effects of sheeting.

The reference to "debris" in this specification includes leaves and/or other matter which may commonly accumulate on a roof surface of a building.

Brief Description of the Drawings The present invention will become more fully understood from the following detailed description of a preferred but non-limiting embodiment thereof, described in connection with the accompanying drawings, wherein: P:\wpdocs\wl\work\patlmts\dmaing\akozA FILTER FOR GUTTERING as amwndd at 3 Novanbe 2005 (2).doc-08/11/05 -7- S- Figure 1 depicts a side cross-sectional view of a first embodiment of the n present invention installed across a gutter wherein an engagment portion is fitted to a tiled roof surface.

-Figure 2 depicts a side cross-sectional view of the first embodiment of Sthe present invention installed across a gutter wherein an engagment I portion is fitted to an adjacent corrugated roof surface.

-Figure 3 depicts an on-view of the first embodiment of the present invention installed across a gutter wherein an engagment portion is fitted to a tiled roof surface.

-Figure 4 depicts an on-view of the first embodiment of the present invention installed across a gutter wherein an engagment portion is fitted to a corrugated roof surface.

Figure 5 depicts a top view of the first embodiment of the present invention in stand-alone fashion.

Figure 6 depicts a first embodiment of a saddle clamp.

Figure 7 depicts a first embodiment a right-angle trim.

Modes for Carrying out the Invention Figures 1 and 3 depict a first embodiment of the present invention installed on to a tiled roof surface (6a) whilst Figs. 2 and 4 show the first embodiment installed on to a corrugated roof surface (6b).

Figure 5 shows the first embodiment filter mesh more clearly in stand-alone fashion. The filter mesh is made from an expanded aluminium material having P:\wpdo s\wl\wor kpatts \d r aing akoz\A FILTER FOR GUTTERING s ammded at 3 Novambcar 2005 (2).doc-08/I I/OS -8a first and second surface (la,lb) and a plurality of channels extending n between the first and second surface (la,lb). The channels each include substantially uniform diamond-shaped cross-sections of 4 x 4 mm dimensions.

SImportantly, the diamond-shaped cross-section of each channel at the first surface (la) is substantially in straight alignment with the diamond-shaped crosssection of the channel at the second surface (1 b).

The first and second surfaces (la,lb) are substantially smooth planes that are parallel to each other on either side of the filter. The first and second surfaces (la,lb) are also separated by a wire diameter of approximately 0.6mm before powder-coating of the expanded aluminium. After powder coating, the wire diameter is approximately 0.7 mm.

The aluminium material of the first embodiment filter mesh includes a powdercoating so as to assist in alleviating corrosion as well as to provide a smoother surface upon which leaves and other debris may more easily slide off.

As shown in Figs. 1 to 4, the filter mesh is able to be mounted across the opening (4a) of a gutter In Fig. 1, this is achieved by securing an engagement portion of the filter mesh beneath a row of roof tiles In this example, the engagement portion simply includes an edge of the filter mesh which is nearest to the roof-surface. In this arrangement, the filter mesh material is such that the weight of the tiles causes the engagement portion of the filter mesh to readily contour to the roof surface (6a) without giving rise to air-gaps forming between the engagement portion and the roof surface The filter mesh also readily deforms to complement the contour of the roof surface without the need to pre-heat and/or pre-treat the filter mesh material.

As shown more clearly in Figs. 1 and 2, a gutter-engaging region of the filter mesh is attached to a lip of the gutter by using a metal right angle trim which is secured jointly over the gutter-engaging region of the filter mesh P:\pd.ssIwo\patmtdr.ftig\kk.s\A FILTER FOR GUTTERING .as m &d a 3 Nos-.b 2005 (2)do-08l/1105 -9z and the gutter lip and fastened into place using screws and/or rivets. An n example of a suitable right-angle trim (10) is shown in stand-alone fashion in Fig.

7.

In Fig. 2, the engagement portion of the filter mesh is fastened into place on the corrugated roof surface (6b) using either a saddle clamp or, a product n manufactured from the same material as the roof product, which is fastened into place with screws or rivets. An example of a suitable saddle clamp is shown in stand-alone fashion in Fig. 6. Alternatively the filter mesh can be fastened directly on to the roof with screws or rivets without utilizing the saddle clamp Generally, when the first embodiment is installed over the gutter the planar surface of the filter mesh extends in substantially parallel fashion with the slope of the roof surface (6a, 6b).

All such variations and modification which become apparent to persons skilled in the art, should be considered to fall within the spirit and scope of the invention as broadly hereinbefore described. It is to be understood that the invention includes all such variations and modifications. The invention also includes all of the steps and features, referred or indicated in the specification, individually or collectively, and any and all combinations of any two or more of said steps or features.

The reference to any prior art in this specification is not, and should not be taken as, an acknowledgment or any form of suggestion that that prior art forms part of the common general knowledge in Australia.
