(54) A REFLECTIVE DEVICE FOR CARRYING VARIABLE INFORMATION FOR EXAMPLE FOR ADVERTISING PURPOSES (71) 1, HAROLD JACKSON, a British subject of Flat 5, 123-5 Gloucester Place, London, W.1, formerly of 8 Parsonage Lane, Windsor, Berkshire, do hereby declare the invention, for which I pray that a patent may be granted to me, and the method by which it is to be performed, to be particularly described in and by the following statement: This invention relates to a reflecting device for display of information, and particularly although not exclusively to a reflecting device useful for advertising purposes.

According to the invention in its broadest aspect, there is provided a reflecting device for the display of information which includes a substantially flat layer of highly reflecting material placed over a backing member and over which is laid a single sheet of transparent or translucent synthetic plastics material having the information printed thereon, the flat layer, the backing member, and the sheet all being held together by a frame carrying a pane of plain glass which can be opened for removal and replacement of the sheet.

Desirably the frame may be hinged. The glass in the frame serves for holding the sheet in its proper position. Of course by opening the frame the sheet may be changed and replaced by another similar sheet bearing different information, for example a different advertising message.

The reflecting material may be supported upon a resilient backing constructed to ensure so far as possible that the reflecting surface of the reflecting material is kept perfectly flat when the frame carrying the pane of glass is closed.

As an alternative, the reflective device may be incorporated in a display cabinet or display frame, and such a cabinet or frame could be installed in supermarkets, retail outlets, or other public places. Since the highly reflective surfaces serves as a conventional mirror, it is to be expected that the public will give more attention' to the device than is the case with a conventional advertising poster or showcard. An important feature of the invention is that one obtains the extra viewer-interest accruing to a mirror without the inflexibility of having an advertising message printed on the mirror glass.

It has long been known to use conventional silvered glass mirrors to carry an advertising message which may be -placed - thereon by silk-screen printing or other means, but to change the content d the message on such mirrors is extremely difficult, if not impos silk. This severely limits the utility of such devices. By the use of the present invention, the advertising or information legend can be changed as often as desired with little expense compared to prior reflecting devices which have been proposed for use in adverr tising.

In a preferred version of the invention the sheet is cellulose acetate sheet printed on its rear surface, that is, on the surface which in use is in contact with the reflective material.

The latter is preferably a commercially avail able- highly-reflective film.

'The legend on the sheet may be applied thereto by any convenient means: for example by lithography or by silk screen printing. Materials other than cellulose acetate sheet may be used, provided that they are 'transparent; and can receive the desired legend.

The reflective material may be an acrylic plastics sheet upon which a highly-reflective layer of. aluminium has been vapour deposited.

The invention will be better understood from the following description of an illustrative and non-limiting embodiment, given with reference to the drawings accompanying the Provisional Specification, in which: Figure 1 is a perspective view of a franied reflective device according to one example of the invention, and Figure 2 is a vertical cross section on a smaller scale through the device of Figure 1.

Referring firstly to Figure 1, the reflective device illustrated includes a backing member or support plate 10 of rectangular shape which can. be secured by any convenient means to a wall, door, window, or other suitable support. Over its front surface is positioned a highly-reflective synthetic plastics material 12. This is secured by a frame 14 around the four edges of the backing member 10. The frame 14 has a front window formed by plain glass and is hinged about a horizontal pivot 16 so that it can be opened and closed to allow insertion and removal of a sheet of transparent synthetic plastics material 18 which carries the desired information or, legend 20. As shown, the frame 14 'can be hinged relative to the backing plate 10 about a horizontal axis, and it is held in its closed position by a clip generally indicated at 22. However, it will be understood that the frame could be hinged about a vertical axis and other securing means could be employed. In some case, a lockable cabinet type of construction may be appropriate.

The sheet of transparent synthetic plastics material 18 has the legend printed on its rearside, for preference, and is desirably of .thin gauge. While in this specification it has been referred to as transparent, it will be realised that a translucent sheet which transmits enough light for the viewer to see his reflection reasonably clearly may also be suitable in certain applications of the invention. The sheet 18 is a thin sheet, by which is meant that its thickness is in general not greater than that of a sheet of thick writing paper.

As an alternative to having the film 12 tightly stretched over the backing plate 10, the plate 10 then being rigid or having four rigid margins, the backing plate may carry a resilient pressure pad as shown in Figure 2. In Figure 2 there is illustrated a device which has a backing board 10 which carries a rectangular pressure pad 11. Over this is stretched the highly-reflective synthetic plastics film 12, and the frame 14 not shown in Figure 2, has a front "window" formed by a pane of plain glass 24. Between the glass 24 and the film 12 is disposed the replaceable thin sheet of synthetic plastics material carrying the desired information or legend.

This is denoted by 18 in both the Figures.

The information or legend may be placed on the sheet 18 by "micro-dot" printing, or by a silk screen process, or by any other suitable means.

If it is desired to produce a "distorting mirror" effect, for example when using humorous advertising messages, the backing member 10 may be curved or undulating.

Usually, however, it will be flat.

In use, it will be realised that the device as a whole has the appearance of a mirror to the onlooker, but that the advertising message or other legend is carried in a posi tion where it will inevitably be seen and noticed by an onlooker. Also, since it is presented in close juxtaposition to the image of the onlooker, it is to be expected that a favourable mental impression in the mind of the onlooker will be created. In order to change the "message" or legend, it is merely necessary to open the frame 14, take out one sheet 18, and replace it by a similar sheet bearing a different legend. In consequence, it will be realised that the information presented can very readily be changed but in all cases, the message concerned appears to the onlooker in close association with his or her own reflection.
