PREFERRED EMBODIMENTS OF THE INVENTION Referring to Figs. 1 2, one embodiment of the wall panel system according to the present invention includes a supporting structure in the form of a mounting board 1, a plurality of retaining brackets 2 and a plurality of plates 3.

The mounting board 1 includes a plurality of locating slots 4 at predetermined locations. In the embodiment depicted in Fig. 1 the slots are configured in a square grid, although it should be appreciated that the locating slots 4 can be configured in various other arrangements. Furthermore, it should be appreciated that other types of openings, such as round holes, may be used instead of slots. Alternatively, the retaining brackets 2 can be mountable to the board 1 by mechanical fixing means such as screws or bolts or by providing them with projections engaging in an interference fit with holes provided at predetermined locations on the board.

Each bracket 2 is engagable with a slot 4 on the mounting board and includes a supporting lip 5 for engagement with a plate 3, as shown in Fig. 2. In one embodiment, illustrated in Fig. 3, the slots and the brackets are adapted so as to allow two brackets 2, placed on the opposite sides of the mounting board 1, to be co-located in a single slot 4. This embodiment permits plates 3 to be mounted on each side of the mounting board 1.

Each plate has a pair of opposing edges 6 which engage the lips 5 of a corresponding pair of opposing brackets 2. The plates engage with the lips in an outwardly bowed configuration, as illustrated in Fig. 2. In order to be sufficiently flexible, each plate has a relatively thin cross-section. Preferably the plates are made of a suitably resilient material, such as plastic or wood. In the embodiment depicted the plates are resiliently deformed in order to engage between the lips of a pair of brackets. The resilient nature of the plate creates a force which acts against the lips of the brackets and assists in retaining the plate in position.

The plates 3 are arranged on the mounting board such that the first pair of edges 6 of each two adjacent plates are orthogonal, as best shown in Fig. 4. As illustrated in Fig. 5, each plate includes a second pair of opposing edges 9, each convexly shaped so as to conceal the retaining brackets 2 holding the corresponding adjacent plates 3, as illustrated in Fig. 4.

In one practical example, the mounting board 1 is of the order of 3 mm thick and made of plywood or plastic. The slots 4 are of the order of 200 mm long and 8 mm wide and the distance between their centres is approximately 240 mm. The plates 3 are of relatively thin cross-section, their thickness typically being less than several millimetres, and are made of a resilient material such as plastic or wood. The plates 3 can have a variety of finishes, or can be coloured in a plurality of colours, so as to create the desired visual appearance.

One preferred embodiment of the mounting bracket 2 is illustrated in Figs. 3 6. Each bracket includes a base plate 10, a tongue 11 for gripping onto the wall of the slot, first and second stabilising flanges 12, 13 and a lip 5 for engaging an edge of a plate. The height of the stabilising flanges 12 and 13 is chosen to provide sufficient clearance space underneath the tiles so as to allow easy mounting of the plates. It will be appreciated by those skilled in the art that there are many other possible constructions and profiles of the brackets, some of which are illustrated in Figs. 7a to 7d. Preferably the brackets are produced by means of extrusion or moulding, either being a relatively inexpensive production method that permits the use of inexpensive materials such as aluminium or plastic.

In another embodiment of the invention the mounting of the plates 3 on the mounting board 1 can be achieved without the use of retaining brackets. For example, grooves or slots may be formed directly in the surface of the mounting board 1 to allow mounting of the plates directly onto the board, as illustrated in Fig. 8. In this embodiment grooves 14 are formed in the mounting board 1 at predetermined locations. Each groove 14 includes a lip 5 for engaging and supporting the edge of a plate 3. Typically the grooves are arranged on the board in the form of a square grid, although it should be appreciated that other configurations are possible.

-6- In a further embodiment, the supporting structure takes the form of a set of interconnectable retaining brackets, thereby alleviating the need for a mounting board.

In this embodiment the retaining brackets are adapted to be connected together by means of joiner elements. One embodiment of a bracket 15 is illustrated in Fig. 9.

One side of each bracket includes supporting lips 5 for locating and supporting the edge of a plate. The opposing side 16 of the bracket includes lips 17 which define a recess adapted to receive the tongue 18 of a joiner element 19 illustrated in Fig. The joiner element 19 includes two or more tongues 18 for connecting two or more brackets to form a frame work for supporting the plates. A schematic illustration of some possible type of engagements is illustrated in Figs. 11 a to 11 Id.

Figs. 12 to 15 illustrate a further embodiment of the present invention. This embodiment of the invention provides a modular arrangement for constructing a supporting structure for the plates 3 from a series of interlocking members 20. In the embodiment depicted the members 20 are substantially square in shape, although it should be noted that other shapes and configurations are possible. The outer periphery 22 of each member is provided with projections and recesses 23, 24 to engage with corresponding recesses and projections in the outer periphery of adjacent members.

When adjacent members are correctly located in position, the projection on one member is received in a recess of the adjacent member. A clip 25 is used to lock the adjacent members together. A recess 26 is provided in the outer surface of each member to receive the clip 25 so as to provide a substantially flush fit for the clip when it is in a locking position. The outer surface of the members is provided with supporting lips 5 for locating and supporting the edge of plates 6 as per the other embodiments of the invention previously described.

It should be noted that instead of flat and flexible plates which engage with the retaining brackets by means of bowing, it may be possible to use pre-curved plates.

These alternative plates may require alternative means of attachment, but can still include suitably shaped side edges that conceal these attachment means.

There are different possible arrangements for the periphery of the board. One arrangement can include framing the edges of the mounting board with extruded or moulded trim pieces that can be identical of different from that of the retaining brackets. It should be appreciated that for a better decorative framing effect the trim pieces can be attached not to the periphery of the board itself, but to border pieces attached to the periphery, but being transversal to the board.

It will be appreciated that the wall panel system, according to the present invention, can be provided in a kit form that is easy to assemble, to use and to disassemble. In use, it also allows an easy rearrangement of the plates into different images. It can also have a strong aesthetic appeal that can classify some of the embodiments of the invention as art objects. The visual impact can be modified by colouring the plates or covering them with a sheet material carrying a particular artistic or otherwise image. The images that can be visualised in this way can have various sizes. One particular way of doing this with a large image is by printing the image on a sheet material (for example vinyl), dividing it into portions corresponding to the size of the plates, cut it into pieces and adhere these to the corresponding plates.

This will result in an artistic presentation of an image that can be substantially larger than the size of a single plate. A back lightning provided by placing light source/s behind the plates can further enhance the visual effect.

Although the invention has been described with reference to a specific example, it will be appreciated by those skilled in the art that the invention can be embodied in many other forms.
