The edging member includes a substantially planar rim portion (1) adapted to be attached to said surface member (9), a lip (2) provided along one edge of said rim (1), and, a flange (3) depending from said lip (2) in a substantially transverse direction to said rim so as to fit within said aperture. A second aspect relates to an aperture edging device (30) which has an intermediate section (31) with a pair of arms (32, 33) depending transversely therefrom to form a substantially c-shaped configuration to envelope the edge portion of the surface member. An advantage of the present invention is that a strong rigid vertical face is created in the plaster board, minimising the possibility of damage thereto. Light fittings, or other fittings may be associated with the device.

Description: APERTURE EDGING MEMBER AND METHOD Technical Field of the Invention The present invention relates to improvements in the provision of apertures in building board materials, such as in ceilings and/or walls. In one aspect, the present invention relates to a method and apparatus for forming a substantially smooth aperture within a ceiling or wall or other surface member, and also to an apparatus and method for installing a fitting, such as a light fitting, in a manner such that it does not overlay or protrude from said surface member. In a second aspect, the present invention relates to a method and apparatus for forming a smooth edge in an aperture formed within a surface member. Description of the Prior Art Presently known methods of installing a fitting, such as a light fitting, air conditioning duct, sprinkler, or other fitting in a ceiling, involve forming a cutout in the ceiling, and then supplying the fitting within the cutout. Such known fittings are provided with a flange or the like fabricated by the manufacturer of the fitting, such that, when installed any roughened edge about the cutout is covered by the protruding flange overlying the ceiling surface. Such a flange may discolour, rust, or begin to separate from the 'line', i.e., the smooth surface, of the ceiling, over time. Furthermore, such a flange also causes a visual disruption to the smooth surface of the ceiling. Not only is this aesthetically unappealing, but, where it is necessary to paint or provide some form of coating to the surface, either the fitting and/or its associated flange must be removed, or, difficulty is encountered avoiding application of the paint or other coating to the flange portion, at least, of the fitting. Summary of the Invention The present invention seeks to provide an apparatus and method for forming a substantially smooth aperture within a surface member, such as a ceiling or a wall, which overcomes the disadvantages of the prior art. The present invention also seeks to provide an apparatus and method for forming a substantially smooth aperture within the surface member for attaching a fitting thereto but, which allows for elimination of a flange or the like overlaying the surface member. The present invention also seeks to provide a means for installing a fitting, such as a light fitting, in a ceiling in a manner such that no visual disruption is provided to the line of the ceiling, which has the added advantage that less difficulty is encountered in painting or applying other coatings to the surface member, etc, and, in which the structural rigidity of the aperture is improved.

Detailed Description of Preferred Embodiments Throughout the drawings, like numerals will be used to identify similar features, except where expressly otherwise indicated. It will be understood that a first aspect of the invention is described with reference to Figs. 1 to 7, whilst a second aspect of the invention is described with reference to Figs. 8 to 11. As illustrated in the Figs. 1 to 7 of the drawings, a support member 15 for supporting a light fitting or other fitting to a cutout in a surface member is shown, which includes a substantially planar rim portion 1 , a lip 2 provided along one edge of the rim 1 , and a flange 3 , depending from the lip in a substantially orthogonal direction to the plane of rim 1. A light fitting 17 may be installed within the support member 15, and be retained therein by suitable attachment means. The arrangement illustrated in the drawings includes an attachment means, which is embodied in the drawings as a flange 7. The light fitting may be in the form of a conventional type downlight as presently commercially available, or may be custom designed to particularly suit the support member. In the embodiment shown, a conventional downlight is shown, including a housing 4 which is typically made of cast aluminium, which may be polished and sealed or painted, with a central aperture to suit the lamp 12. To retain the lamp 12 and lamp housing 4 within the support member 15, spring clips 5, held in place by cleats 7, may be provided which catch over the top edge 13 of flange 3. The cleats 7 may be fixed to the inner face of the lamp housing. It will be appreciated by persons skilled in the art that any alternative form of attachment means for retaining the lamp 12 within a support member, may be utilised. For example, a cleat and spring circlip 8 may be utilised to retain the lamp 12 in position, in conjunction with cleats 7, such as in the arrangement of Fig. 6. The upper end of flange 3 may be inwardly bent, as indicated by protrusion 11 , against which the edge 4 of the light fitting 12 may abut. It will be understood that a unique feature of this aspect of the present invention is the ability to provide a 'smooth' finished surface 10 right up to the lip 2 of the device 15. When the term 'smooth' is used in this context throughout the specification, it should be understood that what is intended in that there is no visually noticable protruding flange or the like required to be provided overlaying the surface 10. Consequently, a continuous paintable finish right up to the light fitting aperture is provided, resulting in a smooth flush fitting, or a recessed fitting, but with no visual disruption to the line of the ceiling. The rim 1 may be attached to the surface member 9, by inbuilt fastening clips, or like means, or, by using adhesives, screws, nails or any other conventional means. Appropriate roughening or projections 19 may be optionally provided on any of the surfaces of the support member to assist in bending or for improved strength or rigidity. The rim 1 is preferably perforated in a similar manner to the way in which corner edging pieces are perforated when forming corners on plasterboard walls. Alternatively, the rim may be segmented, castellated, or the like. The other components may likewise be perforated, segmented, castellated, or the like. The rim 1 is therefore attached to the surface member 9, and then settable material 10, such as plaster, or other filler material, is supplied over the surface member 9 right up to the lip 2. It will be appreciated that a fitting of any desired shape may be installed into a member of appropriate complementary shape. This may include conventional type circular downlights, whereby the rim would typically be of substantially annular shape, or, any other shape may be provided. This may embody the ability to mould the support member in a variety of shapes depending upon the fitting to be installed. Lights of any desired shape such as rectangular, square, oval, triangle, or any other freeform shape, may therefore be installed, including uniquely shaped designs such as corporate logos, etc. Whilst the present invention is particularly useful for providing apertures in plasterboard ceilings, it will be appreciated that the invention may alternatively be applied to walls or other surface members. Furthermore, it will be appreciated that such fittings may be applied to rendered surfaces, or any other surface which might typically utilise a settable material, such as a plaster, render, or other filler material. The support member 15 may be formed of sheet metal material, plaster, plastics, cardboard or any other suitable material. It will be appreciated that whilst sheet metal material might have the advantage of providing higher structural rigidity, when forming unusual shapes, plastics, plaster, or resin impregnated cardboard may be more preferable in being more easily formed to be of any desired shape. Other materials will become understood to be able to be used, by persons skilled in the art. Whilst the embodiment hereinbefore described is related to a support member for supporting a fitting in a cutout provided within a surface member, it will be appreciated that an alternative embodiment of the invention would be wherein an aperture is desired to be formed within a surface member, wherein the aperture is desired to provide such a smooth (flush) uninterrupted surface, right up to the edge of the aperture, but wherein no fitting is actually desired to be installed. As such, the present invention should be understood to also incorporate such an aperture edging member, for forming such a smooth aperture within the surface member, which incorporates the substantially planar rim adapted to be attached to the surface member, the lip 3 provided about the edge of the rim, and which has a flange 3 depending from the lip in a substantially orthogonal or other transverse direction to the rim, so as to fit within the aperture. It will be appreciated that it may be desirable to provide such apertures simply for aesthetic reasons, or for other purposes. It will also be understood that whilst the embodiment illustrated in the drawings provides the flange 3 to be substantially orthogonal to the rim member 1 , that other transverse angles other than orthogonal may also be provided depending upon the particular aperture and/or fitting desired to be installed. It will be understood by persons skilled in the art that the method of forming the aperture and/or installing the recessed fitting in the surface member includes the primary step of forming a cutout in the surface member, then installing and attaching an aperture member or support member within the cutout, wherein the aperture member includes the substantially planar rim portion 1, the lip 2, and the flange 3, in such a manner whereby the rim portion is attached to the surface member about the cutout, such that the flange fits within the cutout. Thereafter, a layer of settable material is provided over the rim to the lip, and, in the instance where a recessed fitting, such as a light fitting, is adapted to be installed, the fitting is then attached by suitable attachment means to the flange 3. A variation to the invention is to incorporate an inbuilt support structure associated with the flange 1, in the manner illustrated in Fig. 7. Rather than attaching a commercially available down light or recessed light using a spring clip 5, a custom built light fitting may be designed. In such an arrangement, the fitting 15 may be supported by support clips 20, particularly whilst the plaster or other material is setting. Various alterations and modifications to the embodiments hereinbefore described will become apparent to persons skilled in the art. For example, a fire-rated downlight construction, wherein a totally enclosed housing surrounds the light fitting, with an appropriate orifice for wires to pass through, is envisaged. Such a housing may be formed of the same type of material as the ceiling, for example, fire-rated plasterboard or metal, and be attachable atop the plasterboard ceiling using the support member arrangement of the present invention. It will be appreciated that this first aspect of the present invention therefore provides an apparatus and method which is particularly useful in providing a unique means and method of illuminating in providing a smooth surface profile, which is readily incorporated into ceilings and/or walls, using conventional building techniques. The fittings described in the present invention allow the surface plane and the colour to be broken only by the aperture for such a light source. As illustrated in Figs. 8 to 11 of the drawings, the aperture edging device, in accordance with a second aspect of the present invention, generally designated by the numeral 30 comprises an intermediate portion 31, a pair of flange arms 32 and 33 which depend transversely from the intermediate section 31 to form a substantially c-shaped configuration when viewed in cross-section (See Fig. 11). The aperture edging device is adapted to be inserted into an aperture formed within a surface member, such as building board, which, for example, might include plasterboard, fibre cement, compressed fibre cement, composite sheet material or the like. When an aperture is used to provide a light fitting, the device of the present invention is preferably formed to be of annular shape. It will however be appreciated that apertures of any desired shape may be formed, and that therefore any desired aperture edging device, in accordance with the present invention, may be formed of any desired shape. In a preferred embodiment, the device may be provided with a cut or split 34, which may facilitate insertion of the device 30 within the aperture. It may also be formed whereby at least part of the device is of a solid body formation, or may have perforations, segments or castellations. In Fig. 10 is illustrated the aperture edging device 30 installed in an aperture within a building board, for installation of a light fitting 36, whilst enlarged cross-sectional profiles of the device 30 is shown in Fig. 11. As illustrated in Fig. 11, the device, in cross- section forms a c-shape (or inverse c-shape when viewing from the opposed direction). Whilst it will be appreciated that the arms may either depend substantially orthogonal from the intermediate member, in a preferred form, the arms, or at least one of them, may extend at an angle slightly less than 90°, such that the device is inwardly biased to be retained on the building board. Also, in a preferred form, the outer extremity 37 of one of the flange arms 32 is outwardly directed to assist installation of the device over the edge of the board. Fig. 11(a) illustrates the provision of a lip 42 extending longitudinally from the intermediate member. This may be formed such that the fitting sits proud of the ceiling plane. This allows for ease of painting, etc. Fig. 11(b) illustrates a similar arrangement to Fig. 11(a), but without the lip 42. Fig. lie illustrates an alternative embodiment wherein the intermediate section is formed of a pair of attachable members 38 and 39. In a preferred embodiment, the members 38 and 39 may be clipped or otherwise attached to one another by suitable engagement members 40 and 41, and this may be performed in a permanent or releasable manner. Whilst this arrangement overlaps the ceiling, it benefits by providing a strong aperture edging. Fig. 11(d) illustrates a variation, but including an abutment flange 43, against which a light fitting 44 or other fitting may abut. Fig. 11(d) also shows the provision of the lip 42 to which settable material 45 may be provided. Also, shown is that the flange arm 33 is perforated. It may alternatively be formed in an other than solid manner, with appropriate segments, castellations, or the like. Fig. 11(e) shows another variation, but without the lip 42. It will be appreciated that the intermediate portion 31 may incorporate means for attachment of a light fitting, by a screw-in, clipping or other engaging mechanism. It will be appreciated that the aperture edging device of the present invention uniquely provides a device which forms a smooth edge on an aperture in a boarding material, such as plasterboard, or the like. The device provides protection against the destruction or decay of the edge of the plasterboard or like material, and optionally also provides the ability to then install a light fitting or the like about the edge of the device, whereby the edge of the device is provided with improved structural integrity. Once a rigid and vertical face has been formed in the building board the methods of fixing fixtures may be changed. This system provides the introduction of threads, keys or similar male/female components to the fixture and aperture trim. These systems of restraint allow for more rapid installation and removal of fixtures of fixtures without damaging the board into which they are housed. The present invention has been hereinbefore described with reference to a particular embodiment only. It will, however, be understood by persons skilled in the art, that numerous variations and modifications can be made to the invention. All such variations and modifications should be considered to be within the scope of the invention as broadly hereinbefore described.
