Description of Embodiments

[36] It should be noted in the following description that like or the same reference numerals in different embodiments denote the same or similar features.

[37] Figures 1 and 4 show a cornice block 200 according to a preferred embodiment of the present invention. As further described below, the cornice block 200 is mounted to a junction between a wall and ceiling, and is used to locate and install a cornice profile thereto.

[38] The cornice block 200 comprises a shaped constant cross-section body having a depth 260 of between 5 cm to 20 cm in the preferred embodiments. The description below mostly refers to the cross-section profile of the cornice block 200.

[39] In cross-section, the cornice block 200 comprises a ceiling face 202 and a wall face 204 which are oriented at 90° to each other. The ceiling face 202 is an upper horizontal face and the wall face 204 is a lower vertical face. The ceiling face 202 and the wall face 204 are joined by an angled external face 206 which extends at 45° therebetween. The ceiling face 202 and the wall face 204 form the mounting faces of the cornice block 200 for engaging the ceiling and wall respectively.

[40] Opposite to the mounting faces, the cornice block 200 comprises a cornice profile locating recess 210. The locating recess 210 is shaped and is defined by formations 220 which extend generally parallel to each other from upper and lower edges of the cornice block 200. A first formation 220 extends from adjacent a distal edge of the ceiling face 202 and in a direction generally away from the ceiling face 202, and the second formation 220 extends from adjacent a distal edge of the wall face 204 and in a direction generally away from the wall face 204.

[41 ] The formations 220 each comprise an internal face 221 which are parallel to each other and form engagement faces for the cornice profile as described below. The engagement faces can be smooth and parallel 221 as shown in Figure 1 for a friction fit, or can include serrations 222 (Figure 2), curved profiles (Figure 3), or other suitable engagement formation. The engagement faces extend at about 45° relative to the ceiling face 202 and the wall face 204.

[42] The locating recess 210 further includes block mount faces 230 and a profile mount face 240. The block mount faces 230 are disposed adjacent a respective formation 220. Each block mount face 230 is parallel to a respective one of the ceiling face 202 and the wall face 204, and each comprises a guide V groove 232 to accurately position fixing screws 242 in use.

[43] The profile mount face 240 is raised relative to the block mount faces 230, thus forming the block mount faces 230 as deeper recesses within the locating recess 210. The profile mount face 240 is disposed between the block mount faces 230 and oriented at 45° relative to the ceiling face 202 and the wall face 204. The profile mount face 240 is thus parallel to the external face 206. The profile mount face 240 comprises a central concealed fastener 212 having cornice profile attachment means 214 (fixing prongs 214) which extend in a generally outward direction of the locating recess 210. The formations 220 thus define the sides of the locating recess 210 and the profile mount face 240 defines the base of the locating recess 210, with the base (profile mount face 240) having upwardly extending attachment means 214.

[44] Figures 5 to 1 1 the steps of the use of a cornice block 200 for mounting a cornice profile 300 to the junction of the ceiling 402 and wall 404.

[45] Figure 5 shows the ceiling face 202 meeting the ceiling 402 and the wall face 204 meeting the wall 404. The cornice block 200 extends equally outward from the ceiling 402 and wall 404 junction 406. In other words, the cornice block 200 is symmetrical relative to the junction 406.

[46] Figure 6 shows the cornice block 200 being mounted to the ceiling 402 and the wall 404 via fixing screw 242 through the 'V groove guides 232 at the recesses 230 to secure the cornice block 200 to the ceiling 402 and wall 404 adjacent the junction 406 of the structure. The mounted cornice block 200 thus provides a locating recess 210 directed into the interior of the structure in use. The locating recess 210 comprises edge formations 220 for receiving and locating therein a cornice profile. The locating recess 210 further includes an attachment means 214 at a central base portion thereof 212 of the profile mount face 240 for engaging the cornice profile.

[47] Figure 7 shows a cornice profile 300 being presented to the locator recess 210 of the cornice block 200. The cornice profile 300 is an elongate profile and comprises a decorative face 310 and a mount section 320 at an opposite side thereof. The decorative face 310 forms the exposed part of the cornice profile 300 and is decorated with patterns and/or grooves as desired. The mount section 320 in cross-section comprises a central formation 330 which is shaped to be received in the locating recess 210 of the cornice block 200. The central formation 330 comprises edge faces 302 which engage the engagement faces of the cornice profile formations 220. [48] Insertion of the central formation 330 further into the locating recess 210 forces the attachment means 214 of the concealed fastener 212 into the central formation 330, thus retaining the cornice profile 300 to the cornice block 200.

[49] The cornice block 300 is provided with slightly angled edge faces 340 which will engage the wall face 404 and ceiling face 402.

[50] The cornice profile 300 is thus presented in between the formations 220 which act as locating means to guide the cornice profile 300 onto the concealed fastener 214 within the locating recess 210. The shape at the rear central formation 330 of the cornice profile 300 corresponds to the shape of the locating recess 210 to provide a tight fitting connection.

[51 ] Figure 8 shows the cornice profile 300 being engaged by the concealed fastener 212 with the edges of a cornice profile 300 meeting the wall 404 and ceiling 402 with a tight fit.

[52] Figure 9 shows the fitted cornice block 200 and a cornice profile 300 being fully engaged onto the concealed fastener 214. The angled edge faces 340 of the cornice profile 300 are pulled towards to the wall 404 and ceiling 402 resulting in cornice flex 342 to maintain a tight fit against the wall 404 and ceiling 402. The fastener 212 is thus totally concealed and is not visible from or affects the decorative face 310.

[53] Figure 10 is an isometric view showing a plurality of spaced cornice blocks 200 mounted to the junction with cornice profiles 300 mounted thereto. Part sections of cornice profile 300 are shown installed onto a multiple number of cornice blocks 200 that are spaced evenly over the length of the junction between the wall 404 and ceiling 402.

[54] Figure 1 1 shows an isometric detail view of the cornice block 200 with the concealed fastener 212 gripping into the cornice 300. The cornice block 200 is installed at the junction of the wall 404 and ceiling 402 via the screws 242. The inner rear formation 304 of the cornice profile is engaged to the concealed fastener 212 with the rear profile 302 fitting tightly between the locating means 220 of the cornice block 200.

[55] The concealed fastener 212 of the cornice block 200 can be moulded as integral with the block body, or inserted via pushing, nailing, screwing or gluing into position into the profile mount face 240 after manufacture of the block body. One such possible concealed fastener is described in applicant's PCT Application No. PCT/AU2016/000186.
