- fitting into the attachment channels on the second sides of the four framing members the mouth of a housing in which is located a light source, the mouth of the housing being fitted in a direction at approximately right angles to the mirror and the sheet of reflective glass, and securing the mouth of the housing in position.
- The invention further provides a method of producing an illuminated display, the method being characterised by the following steps:- preparing a mirror by etching clear areas corresponding to the outline of material to be displayed, holding the mirror in spaced apart relationship from a sheet of reflective glass, securing a transparency of material to be displayed against the rear of the mirror, positioning a diffuser sheet over the transparency and illuminating the diffuser sheet so that the image of the material on the transparency is projected through the clear areas of the mirror onto the sheet of reflective glass, so that when the display is viewed from the side of the sheet of reflective glass remote from the-mirror, there is produced a multiple reflection of the display.
- The invention will now be more particularly described with reference to the accompanying drawings which show, by way of example only, a preferred embodiment of the invention. In the drawings:
- Figure 1 is a side elevation of a display device according to the invention;
- Figure 2 is a part front elevation of the display device;
- Figure 3 is a typical side elevational sectional view of the display device;
- Figure 4 is a cross section of an extrusion used to form framing members for the display device;
- Figure 5 is a plan view of a back panel-or housing for the display device;
- Figure 6 is a sectional view taken along AA' of Figure 5; and
- Figure 7 is a section view taken along BB' of Figure 5.
- Referring to the drawings, the display device comprises a
plane mirror 120 and a sheet ofreflective glass 130 held in spaced apart relationship at their edges by fourframing members 140. Eachframing member 140 is mitred at each end so that the framing members may be joined to form arectangular frame 150 for the display device. - Positioned behind the
mirror 120 is a back panel orhousing 160 which contains afluorescent lighting unit 170 and atransformer 171 for operating the lighting unit. Thehousing 160 is supported by theframing members 140. The display device.is also provided with astand 180 which is supported by the lower framing member 140a. - Referring to Figures 3 and 4, the
framing members 140 are each formed from an elongate extrusion of high impact polyvinyl chloride (PVC). Integrally formed in the extrusion areU-shaped channels 142 and 143 which support respectively the sheet ofreflective glass 130 and themirror 120. Provided at the mouths of the U-shapedchannels 142 and 143 are pairs of off-setgripping lips 144. Extending between the U-shapedchannels 142 and 143 is awall 145 which is provided with a plurality of grooves so as to provide a nonreflective surface between themirror 120 and the sheet ofreflective glass 130. The use of a black pigment in the PVC extrusion assists in making the wall 145 a non-reflecting surface. Also integrally formed on the extrusion as an element of eachframing member 140 is asupport channel 147 having an L-shaped lip 148 which is adapted to engage and disengage withleg 182 of thestand 180. The other face of thewall 145 together with two overhangingridged grips 149 forms aslot 152 which is used in constructing theframe 150. Spaced from theslot 152 is a housing attachment channel 155 which is defined by aflange 156 having an inwardly facingverge 157, and astrut 158. - Figures 2 and 3 illustrate how the
frame 150 is constructed from theframing members 140. A leg 165a of an aluminiumangle corner piece 165 is inserted into theslot 152 at each mitred end of the lower framing member 140a. A light shim is attached to the inside of each leg of thecorner pieces 165 using a double sided adhesive pad to ensure that the corner pieces are held in position by friction (the pads or shims are not shown in the drawings). Aslot 152 of aframing member 140 is placed over the upstanding leg 165b of eachcorner piece 165 and pushed into engagement to form a U-shaped receiver. Themirror 120 and the sheet ofreflective glass 130 are then positioned in the U-shapedchannels 142 and 143 of the threeframing members 140 of the U-shaped receiver. The frame is then completed using afourth framing member 140 and twofurther corner pieces 165. - The constructional details of the
housing 160 are shown in Figures 5 to 7. Thehousing 160 as shown in plan view is generally rectangular in shape. Theback wall 200 of thehousing 160 is provided with akeyhole slot 210 to enable the display device to be mounted on a wall by a screw or the like (not shown). Theedge portion 220 of the housing is sloped at an angle for insertion into and co-operation with the attachment channels 155. When theedge portion 220 is underneath theflange 156 and pressing down on thestrut 158, aself tapping screw 225 is screwed into theedge portion 220 from theflange 156 so as to secure the housing in position in the frame. A total of fourscrews 225 are used to secure thehousing 160. A number of single sidedadhesive sponge pads 230 are attached to theframing members 140 at the area of contact between theframe 150 and the main body of thehousing 160 to assist in securing the back panel in position. - The
lighting unit 170 is attached to theback wall 200 of thehousing 160 by double sidedadhesive pads 235 and thetransformer 171 is attached to the housing by plastic pop rivets 240. The inner surface of thehousing 160 is white so as to reflect the light from thefluorescent lighting unit 170 on to the rear of themirror 120 which is chemically etched to define a display or the outline of a display. The outer surface of thehousing 160 is dark coloured so as to provide a non-reflecting surface for stray light. To provide for the two different coloured surfaces, thehousing 160 is vacuum formed from a laminate plastics material. - A
light diffuser sheet 167 is secured to the rear of the reflecting surface of theetched mirror 120. Thelight diffuser sheet 167 is a sheet of translucent material (e.g. flexible P.V.C.) which is placed in front of thelighting unit 170 to achieve even distribution of light and to bear screen printing of matter to be displayed. Thelighting unit 170 projects the display through theetched mirror 120 onto the sheet ofreflective glass 130 which reflects the display back to themirror 120 which in turn reflects the display back to the sheet of reflective glass and so on, thus achieving a multiple reflection of the display. Such a multiple reflection is known as "an infinity effect". The multiple reflection of the display is only achieved when the light to the rear of the sheet of reflective glass 130 (i.e. lighting unit 170) is more intense than the light to the front of the sheet ofreflective glass 130. - The display device may be used as a point of sale advertising device or a decorative device and may be used for example, in hotels, lounges, clubs or homes.
- The production of an illuminated display by the method just described is technically limited by the screen printing process used to reproduce the display material matter on the light diffuser sheet. A significantly better effect can be achieved by using a
transparency 166 in place of all or a part of the screen printing. - A display device for advertising a product such as a liqueur would ideally contain (1) a
mirror 120 etched to define the outline of the matter to be displayed, (2) alight diffuser sheet 167 screen printed to provide a proportion (e.g. lettering) of the display and (c) a photographically producedcolour transparency 166 of a bottle of liqueur. Thetransparency 166 is secured to the rear of themirror 120 between the latter and thediffuser sheet 167. The screen printed display produces a bold clear display of the printed matter and thetransparency 166 produces a detailed image of the bottle of almost three dimensional clarity. - The above display arrangements can also be used with other display devices such as, for example, illuminated clocks.
- The method of producing display images described is particularly suited for point of sale advertising devices, but has numerous other applications.
