Abstract

An illuminated sign assembly comprises a sign holding member 1 containing a light source 5, the holding member having a vertical slot 8 formed therein, which, in use, receives a transparent or translucent member 10 having two planar substantially parallel surfaces 11, 12 and at least one peripheral edge 20 having a chamfered surface. A filter 17 is positioned between the light source 5 and the transparent member 10 such that light transmitted from the light source 5 to the transparent member 10 is coloured to the filter 17. The filter 17 is preferably composed of a plurality of differently coloured portions (19), disposed end- to-end and at least one peripheral edge 20 of the transparent member 10 is preferably of arcuate or wavelike form. When a multi-coloured filter is used and because of the reflective nature of the chamfer a moving sign is produced upon change of position of an observer O. <IMAGE>

Description

SPECIFICATION An illuminated sign This invention relates to an illuminated sign.
It is the object of the present invention to provide a more eye catching and noticeable form of illuminated sign.
The present invention consists of an illuminated sign assembly comprising a sign holding member, containing a light source, said holding member having a vertical slot formed therein which, in use, receives a transparent, or translucent, member, having two planar, substantially parallel, surfaces and at least one peripheral edge having a chamfered surface, a filter positioned between said light source and said transparent member such that light transmitted from said light source to said transparent member is coloured by said filter.
The invention will now be described, by way of example, with reference to the accompanying drawings, in which: Figure 1 is an isometric view of one embodiment of the invention; Figure 2 is a view taken in the direction of the arrow X on Figure 1 , with an end member removed; Figure 3 is a reference view of another embodiment of the invention; Figure 4 is a cross-section taken along the line IV--IV of Figure 3.
The illuminated sign assembly shown in Figures 1 and 2 comprises a sign holder 1 having a longitudinally extending cover 2 with end members 3 (one shown) and a base plate 4, containing a fluorescent lamp 5, with associated mounting means 6 and a choke and starter 7 of known type, secured to the base plate 4. A vertical, longitudinally extending slot 8 is formed along the upper surface 9 of the cover 2 to allow the insertion of a sheet of transparent or translucent material 10, preferably an acrylic plastics material e.g. "Perspex" (Registered Trade Mark), the front and rear faces 11, 12 of the sheet 10 being substantially parallel and having the inserted edge 13 in perpendicular relation to the faces 11, 12.The slot 8 is positioned such that light emitted from the fluorescent lamp 5 is transmissible through the edge 13 of the sheet 10. A horizontal longitudinally extending slot 14 is positioned between the edge 13 of the transparent sheet 10 and the lamp 5, the slot 14 having horizontal brackets 15, 16, to allow the retention of a coloured filter 1 7. An aperture 18 is provided in the end members 3 so that one colour filter 1 7 may be readily exchanged for another.
The filter 1 7 may have any number of differently coloured sections 19 and the filter 1 7 is so positioned as to provide support for the sheet of transparent material 10.
The unsupported periphery 20 of the sheet 10 is of curved cross-section, chamfered and polished. For display, the illuminated sign is arranged so that when viewed directly, by an observer 0, the trailing edge 24 of the chamfered periphery 20 is remote from the observer 0. An inscription 21 engraved on the sheet 10, for a preferably visual effect, should be engraved on the face 12 adjacent the trailing edge 24 of the chamfered periphery 20. Then, when viewed by an observer 0 the inscription 21 and the top chamfered edge 22 take on the hues of the coloured filter 17.
In another embodiment, two sheets of transparent material 30, 31 of a similar form to that described above, are placed in the slot 8.
Advantageously, any inscription is placed on one sheet 30 while the other 31 is left blank, thus allowing all the light to be transmitted to the top chamfered edge 34 which is of curved crosssection, to give a more intense coloration.
In both the embodiments of the invention, the top chamfered edge of the signs may be arcuate or "wave-like" in shape as illustrated in Figure 3.
This variation produces interesting psychedelic patterns when used with a mutti-coloured filter, due to the many reflective angles created by the "wave-like" edge.
It will be readily appreciated that, when a multi-coloured filter is fitted, due to the reflective nature of the chamfered edges of the sheet, a change in the relative position of the observer will result in a change in the relative position of the observed colour on the chamfered edges of the sheet, thus giving the effect of a "moving" sign.
Claims
1. An illuminated sign assembly comprising a sign holding member, containing a light source, said holding member having a vertical slot formed therein which, in use, receives a transparent, or translucent member having two planar, substantially parallel, surfaces and at least one peripheral edge having a chamfered surface, a filter positioned between said light source and said transparent member such that light transmitted from said light source to said transparent member is coloured by said filter.
2. An illuminated signal assembly as claimed in claim 1 wherein said filter comprises a plurality of differently coloured portions.
3. An illuminated signal assembly as claimed in claim 1 or 2 wherein inscriptions are engraved.
upon one planar surface of said transparent sheet.
4. An illuminated sign assembly as claimed in claim 3 wherein said inscriptions are engraved upon the surface of said transparent sheet adjacent the trailing edge of said chamfered surface.
5. An illuminated sign assembly as claimed in claims 1 to 4 positioned such that when viewed directly, by an observer, the trailing edge of said chamfered surface is remote from said observer.
6. An illuminated sign assembly as claimed in any preceding claim wherein at least one peripheral edge of said transparent member is of arcuate or wavelike form.
7. An illuminated sign assembly as claimed in any preceding claim wherein said filter is slidably removable.
