Detailed Description of Preferred Embodiments

[033] Referring to the Figures, there is shown a sign module 10 comprising generally a rear panel 12 and a cover 14. The sign module 10 is provided to display a single symbol, being a number in the embodiment shown. While the sign module 10 shown is used to display a number, it will be appreciated that the sign module 10 may be configured to display other symbols.

[034] In the embodiment shown, the rear panel 12 and the cover 14 are both rectangular in shape. The cover 14 is securable to a front side of the rear panel 12 by suitable means, such as securing screws 16.

[035] The rear panel 12 includes a recessed portion 18 in the front side. The recessed portion 18 comprises a central rectangular recess defining a raised edge portion 20 extending around the periphery of the front side of the rear panel 12. The periphery of the cover 14 engages with the edge portion 20 of the rear panel 12 and the securing screws 16 are received through holes in the periphery of the cover 14 aligned with corresponding holes in the edge portion 20 to secure the cover 14 to the rear panel 12. [036] The rear surface 27 of the cover 14 includes an outwardly protruding flange 56 provided to be received inside the inner edge of the recessed portion 18. A seal 52 is provided around the connection between the cover 14 and the rear panel 12 to seal sign module 10.

[037] The rear panel 12 of the sign module 10 is provided with an illumination device such that the illumination device emits light outwardly through the cover 14. The illumination device in the embodiment shown comprises a light panel 22. The light panel 22 comprises a rectangular panel including an array of light emitters 24 extending across its surface. The light emitters 24 are arranged across the surface of the light panel 22 such that light is emitted outwardly in the direction of the cover 14.

[038] The cover 14 includes a front surface 26 and a rear surface 27. The front surface 26 is located opposite the rear panel 12 in use and the rear surface 27 is located adjacent the rear panel 12 in use. The rear surface 27 of the cover 14 includes a plurality of recesses 28 (as best seen in Figures 8 and 9). The recesses 28 are provided in a configuration such that the recesses 28 may form one or more symbols when the recesses 28 are either illuminated or blacked out. In the embodiment shown, the recesses 28 are provided in a standard figure 8 type configuration such that the recesses 28 may form each of the numerals from 0 to 9.

[039] The sign module 10 is provided with a plurality of first inserts 30 and a plurality of second inserts 32. Each of the first inserts 30 and the second inserts 32 have a shape corresponding to the shape of the recesses 28. Each of the first inserts 30 and second inserts 32 may therefore be received into one of the recesses 28. Peripheral edges of the first and second inserts 30 and 32 include a plurality of lugs 54. The lugs 54 are provided to be received in corresponding indents 55 provided around the inner edges of the recesses 28, when the inserts 30 and 32 are received in the recesses 28, to locate the inserts 30 and 32 within the recesses 28.

[040] The cover 14 is formed from a transparent material, such as a transparent plastic material. The rear surface 27 of the cover 14 is provided with an opaque coating. The opaque coating is preferably black and may be formed by painting or by application of a suitable adhesive sheet material. The opaque coating extends across the rear surface 27 in areas between the recesses 28 such that the opaque coating does not extend within the recesses 28. Inner surfaces of the recesses 28 are therefore transparent such that light passing into the recesses 28 will be emitted outwardly from the front surface 26 of the cover 14.

[041] The first inserts 30 are provided such that when the first inserts 30 are received into the recesses 28, the first inserts 30 block passage of light into the recesses 28 from the light panel 22. The first inserts 30 may therefore be formed from an opaque material or may include an opaque coating on a rear surface thereof.

[042] The second inserts 32 are formed from a transparent or translucent material such that light may pass through the second inserts 32 into the recesses 28. The second inserts 32 may be formed from a coloured transparent material such that light passing through the second inserts 32 and outwardly from the front surface 26 of the cover 14 is coloured. The second inserts 32 include a reflective sheet material 36 secured to a side thereof. The reflective sheet material 36 is a material through which light may pass but which also provides a reflective characteristic such that light incident on the front surface 26 of the cover 14 is partially reflected back out through the front surface 26 by the reflective sheet material 36.

[043] A plurality of clips 48 are provided also around the edge of each of the recesses 28. The clips 48 extend outwardly from adjacent the edges of the recesses 28. Each of the clips 48 is resilient and includes a lug on a side thereof facing the recess 28 such that, as the insert 30 or 32 is pressed into the recess 28, the clip 48 is flexed outwardly and then moves back such that the lug is above the rear surface of the insert 30 or 32. The clips 48 engage with rear surfaces of the inserts 30 or 32 to further secure the inserts 30 or 32 to prevent the disengagement due to vibration or impact. [044] Each of the first and second inserts 30 and 32 includes a lip portion 34 extending outwardly from around the periphery thereof adjacent the rear surface of the insert 30 and 32. As best seen in Figures 1 1 to 13, the thickness of the inserts 30 and 32 is greater than the depth of the recesses 28. The rear surfaces of the inserts 30 and 32 therefore extend outwardly from the rear surface 27 of the cover 14 when the inserts 30 and 32 are received in the recesses 28. The lip portions 34 of the inserts 30 and 32 thereby engage with the rear surface 27 of the cover 14 around the periphery of the recesses 28. The lip portions 34 thereby prevent light passing between the inserts 30 and 32 and the inner edges of the recesses 28. Therefore, when the first inserts 30 are used, light is completely blocked from passing through the recesses 28.

[045] Each of the sign modules 10 includes a power cable 50 provided to receive power from a power source to operate the light panel 22. The power cable 50 includes a first cable portion 38 connected to a first side of a splitter 40 located within a rear recess 42 on the rear panel 12. The rear recess 42 comprises a recess extending around the periphery of the rear panel 12 on a rear side thereof.

[046] The power cable 50 includes second and third cable portions 44 and 45 extending outwardly from a second side of the splitter 40. The first cable portion includes a first connector 46 thereon and the second and third cable portions 44 and 45 include a second connector 47 on an end thereof. The first cable portion 38 extends outwardly through a side edge of the rear panel 12 to connect to the third cable portion 45 of adjacent sign module 10. The second connector 47 on the second cable portion 45 is provided to connect to the light panel 22 within the sign module 10. In this way, a plurality of sign modules 10 may be connected together in series such that power from an external source only needs to be connected to a first of the sign modules 10 in the series.

[047] In use, a plurality of sign modules 10 are mounted adjacent each other as shown in Figures 14 and 15 and connected together as described previously. With the cover 14 removed, a plurality of the second inserts 32 are placed within the appropriate recesses 28 to form the required number and the remaining recesses 28 are filled with the first inserts 30 and the cover 14 is then connected to the rear panel 12. When power is provided to the sign modules 10, the light emitted from the light panel 22 passes outwardly through the second inserts 32 to display the required number. When power is not supplied, the number is still visible via light which is reflected back from the reflective sheet 36 of each of the second inserts 32.

[048] It will be readily apparent to persons skilled in the relevant arts that various modifications and improvements may be made to the foregoing embodiments, in addition to those already described, without departing from the basic inventive concepts of the present invention.
