DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 illustrates a body portion 108 utilised in the cladding apparatus of the present invention. The portion 108 has an inner surface 110 (see FIG. 2) and an outer surface 112 (see FIG. 1). The inner surface 110 and the outer surface 112 extend longitudinally between a leading edge 114 and a trailing edge 116. The leading edge 114 and trailing 116 extend between opposed side edges 118.

The body portion 108 is made has a curved shape having first 120 side portion (see FIG. 3) arranged to be disposed laterally from an arcuate central portion 122 and a second 121 side portion depending from said arcuate portion.

The leading edge 114 (see FIG. 2) is provided with a formation 124 which inter-engages with complimentary formation 126 (see FIG. 1) provided on an adjacent body portion thereby permitting the body portions to inter-engage when laid in a longitudinal sequence (see FIG. 9).

The body portion 108 is also provided with a pair of longitudinally extending elongate support webs 128 on the inner surface 110 thereof. The end portions 130 and 131 of said elongate support webs 128 are both provided with a spigot end portion.

One particular use of the cladding apparatus of the present invention is to finish the side edge of slab members, such as roof tiles to resist ingress of rain water and provide a more attractive look for the roof rather than having the side edges of the tiles exposed. As illustrated in FIG. 9 the tiles 104 are laid in an overlapping pattern over preinstalled roofing battens (not shown). A guide member 132 is laid on the exposed edge of the tiles. The guide member (see FIG. 5) extends longitudinally for the required length of the tiles 104. The guide member has on its lower face 134 a plurality of steps 136 which compensate for the overlapping nature of the tiles to provide a level upper face 140 when laid on the tiles 104. A longitudinal support member 144 (see FIG. 4) is also fixably attached by its inner face 146 to the facsia panel 106 adjacent to the exposed edge of the tiles 104.

Turning to figure 9, the support member 144 is shown extending longitudinally along the length of the overlapping tiles 104. The support member may be attached to the fascia 106 by any convenient means such as gluing or nailing. The support member itself has an outer face 148 into which a pair of recesses 150 and 151 are provided.

The body portions 108 are placed adjacent to the exposed edges of the tiles 102 with the support webs 128 engaging within the recesses 150 and 151 of the support member 144. The first side portion 120 of the body portion 121 is also supported by the grooves 141 in the upper face of the guide member 132. (See FIGS. 4 and 9) The required number of body portions is placed along the exposed edge of the tiles to provide the required finish. Of course both of the opposing side edges of the tiles can be finished using the cladding apparatus of the present invention (see FIG. 4).

The required number of body portions is placed along the exposed edge of the tiles to provide the required finish. Of course both of the opposing side edges of the tiles can be finished using the cladding apparatus of the present invention (see FIG. 4).

Turning to FIG. 10 the cladding system 152 of the present invention is illustrated. The cladding system may be used to clad any convenient cladding surface 156. The cladding surface 156 illustrated in FIG. 10 is a ceiling, however it will be apparent that the cladding system 152 of the present invention may be utilised on other cladding surfaces for example walls be internal or external walls or floors. The cladding apparatus illustrated in FIG. 10 shows a single row of cladding members 157, 159. In practice a plurality of rows of cladding members would be provided adjacent to each other to fully cover the cladding surface. The cladding system of the present invention includes a longitudinal commencing batten member 154 (see FIG. 11) which is attached to the cladding surface by any convenient means such as nailing or gluing. The commencing batten member 154 has a recess 158 which lies in a first plane 160 of the batten member 154. The commencing batten member 154 is also provided with a groove 153.

A plurality of continuing batten members 164 are also attached to the cladding surface 156 spaced at a distance which matches the length of the cladding member 158, 159 that are used. The connecting batten member 164 also has a recess 166 provided in a plane 168 which lies normally to the first plane 160 of the commencing batten member 154 when those members are attached to the cladding surface. The connecting member 164 also has a further recess 169 lying in a plane parallel to the first plane of the commencing batten member 154.

The cladding system might also include a terminating batten member 174 which is attached to the cladding surface at the opposite end to the commencing member 154.

A first cladding member 157 has a projection 162 extending from a web 172 which depends from the cladding member 157. The projection 162 is provided with an enlarged portion 171 at the end thereof. This 171 portion is for locating within the recess 158 of the commencing batten member. The leading section 176 of the cladding member continues along the face of the commencing batten member 154. The trailing portion 178 of the cladding member 157 also has a projection 170 with an enlarged portion 171. This enlarged portion 171 engages in the recess 166 of the connecting batten member. An adjacent cladding member 159 with a web 172 and projection 162 is then engaged within the recess 169 of the connecting batten member 164. The required of connecting batten members 164 are provided on the cladding surface with corresponding cladding members 159 and engaged therein. The cladding member 159 that is adjacent to the terminating batten member 174 is then engaged within the recess 176 of that batten member, therein completing the column. It will be appreciated from FIG. 10 that the cladding members are, when installed, in an abutting relationship within a single row, as illustrated. Also, the side edges of adjoining rows will, when installed be in an abutting relationship.

It will be realised by those skilled in the art that the present invention provides a cladding apparatus that is quick easy to install when compared with current apparatus in use. In particular, the ability to install the cladding by a simple sliding action rather than through the use of specialist tools represents an improvement upon current cladding apparatus and systems.

It will of course be realised that while the above has been given by way of illustrative example of this invention or such another modifications and variations thereto as would be apparent to persons skilled in the art deemed to fall within the broad scope and ambit of this invention as defined in the claims appended hereto.
