(54) REFLECTIVE OR DECORATIVE ARTICLES
(71) We, E. J. PRICE (DEVELOP
MENTS) LIMITED, a British Company of
Melchett Road, Birmingham Factory
Centre, Kings Norton, Birmingham B3 3HL, do hereby declare the invention for which we pray that a patent may be granted to us and the method by which it is to be performed to be particularly described in and by the following statement:
This invention relates to reflective or decorative articles.
From one aspect the present invention consists in a method of making a reflective or decorative article comprising a transparent or translucent body backed by a sheet of metallic foil at least partly visible through the body, the method being characterised in that the back of the body is shaped to provide projections and/or indentations, the foil is pressed into position against the back of the body so that its shape conforms at least partially to the shapes of the projections and/or indentations, the nature of the foil being such that in conforming in this manner it does not tear or tears only locally, and the foil is secured in that position at the back of the body.
From another aspect the present invention consists in a reflective or decorative article comprising a transparent or translucent body backed by a sheet of metallic foil at least partly visible through the body, and made by the method set forth in the last preceding paragraph.
The transparent or translucent body may be uncoloured or it may be coloured. The body may be formed from any suitable material such as glass or a plastics material.
Although the body may be of a milky or cloudy appearance, that is it may merely be translucent, the body is preferably truly transparent even though it may be coloured or tinted. The body may comprise a sheet or strip of substantially uniform thickness and of relatively great extent. Alternatively the body may be of more complex shape and may be formed, for example, as a moulding or casting.
The back of the body may be formed with a plurality of parallel ribs or grooves to provide a "reeded" pattern, or it may be formed to provide an array of mounds or hollows of round, pyramidal or prismatic shape. The foil may conform fully with the shape of the back of the body or it may conform only partially with the shape of the back of the body. For example where the back of the body is formed with grooves the foil may reach fully to the bottom of each groove or it may reach only part of the way into each groove.
The foil is preferably pressed by means of a pressure pad or roller of resilient material, the pressure being applied progressively from one area of the foil to another. Where the body is of a suitable shape, for example where it is in the form of sheet or strip, it is preferred to place foil against the back of the body and to pass the body and foil together between a pair of rollers, at least the roller behind the foil (which may conveniently be referred to as the pressure roller) being resilient. Alternatively the pressure roller may be shaped with a pattern complementary to that of the back of the body so that the interengagement of the body and pressure roller presses the foil into the desired shape.
The foil preferably comprises a thin metal sheet. Preferably the sheet of foil is no more than one thousandth of an inch thick. The sheet of foil is preferably unsupported, but it may be of the kind mounted on a supporting film such as a film of plastics material. If that film is transparent or translucent the foil may be disposed so that the supporting film lies between the body and the metal sheet.
Aluminium sheet, similar to that marketed as kitchen foil is particularly suitable for use in the present invention. Such foil is rather less than one thousandth of an inch thick.
The sheet preferably has a shiny, mirror-like finish, but if such a sheet is too highly reflective it may be replaced by a sheet with a matt or roughened surface. The sheet may be uncoloured or coloured as desired.
The foil may be held against the back of the body solely by mechanical means, as for example by a backing sheet secured against the back of the body. It is preferred, how ever, to secure the foil in place with the aid of an adhesive, preferably a thin layer of adhesive. The adhesive is preferably colourless and transparent, but use could be made of a translucent adhesive, or a coloured adhesive, or one that is both translucent and coloured. The adhesive may be applied either to the body or to the foil or to both the body and the foil, before the foil is secured in place.
The front of the body may be flat or smooth, but in use the body may then give rise to unwanted reflections resembling those from a mirror. It is often preferred, therefore, that the front of the body should be shaped to provide projections or indentations, which may be similar to those which may be formed on or in the back of the body. Alternatively the front of the body may be frosted or otherwise treated to provide a roughened surface to avoid mirrorlike reflections.
Depending on the intended use of the finished article there may be no need to provide anything behind the foil. As the foil is likely to be relatively weak, however, it is normally Dreferred to protect it in some way. Areatively thin coating of lacquer or like sealing material may be sufficient to protect the foil from damage by atmospheric or other chemical agents. Instead, or in addition, though, it is normally necessary or desirable to provide a backing sheet to protect the foil from mechanical damage. The backing sheet may be of any suitable kind, and may be transparent or opaque. Conveniently it may comprise a sheet of relatively inexpensive plastics material. It may be secured in place adhesively or merely by mechanical means, or both methods of securing it in place may be used together.
In a modification, however, there may be provided an assembly comprising two articles each of which embodies the present invention, the bodies of the articles being formed of sheet or strip material, and the articles being secured together back to back.
If desired a spacing sheet may be provided between the two foils.
Any of those articles including a layer or layers behind the foil may be manufactured by a lamination process in which suitable adhesive materials are disposed between the layers and the whole assembly is subjected to pressure and, as is usually necessary, also to heat to cause the layers to become bonded or laminated together.
The edges of the articles are preferably protected so as to prevent or reduce the likelihood of their being damaged. In particular it is preferred to provide means preventing or reducing the likelihood of moisture or other liquids entering between the body and the foil. The edges of the articles may be coated with a material that sets to provide a seal, or a preformed element such as an adhesive tape or a suitably shaped plastics moulding or extrusion may be fitted to the edges of the article. The protective edging may extend around the whole or around only a part of the periphery of the article.
As indicated above, articles embodying the invention may be used because of their reflective properties, their decorative properties, or both. One particular application of the present invention is to the manufacture of reflectors such as those used on vehicles or as the basis for road signs and similar warning signs. Other applications are to the manufacture of decorative panels such as may be mounted on walls or incorporated in furniture, or used to carry notices such as advertisements, house-names, businessnames, etc.
Although the production of individual shaped bodies by techniques such as moulding may be appropriate in the manufacture of certain types of articles, the cost of production is likely to be relatively high, owing to the high costs of moulds, unless very large runs are undertaken. As far as possible it is therefore preferred to make articles in the form of relatively large sheets, and to cut these up for use as or for use in individual products. Articles formed from flat sheet may be constrained to take up a curved shape.
One method embodying the present invention will now be described in greater detail by way of example, with reference to the accompanying drawings, in which:
Figure 1 is a diagrammatic side view of the manufacture of an article embodying the present invention,
Figure 2 is a cross-section, to a larger scale than Figure 1, through a marginal portion of an article embodying the present invention, and
Figures 3 and 4 are perspective views from the back of relatively small portions of bodies that may be used in articles embodying the present invention.
In the method illustrated in Figure 1 a sheet 10 of transparent polycarbonate material is being backed with aluminium foil 11.
The polycarbonate material may be colourless or it may be coloured red. A typical sheet is eight feet long and four feet wide.
Both the front face and the back face of each sheet are formed all over with a uniform pattern of shallow, pyramidal recesses; for example each face may have a pattern of recesses similar to that shown on the back face of the piece of material shown in either of Figures 3 or 4. The foil 11 is shiny and highly reflective. Typical foil is 0.0007 inches thick. The foil is drawn from a roll of foil 12 over the rear surface of the sheet, and a thin layer of transparent adhe sive is introduced between the foil and the sheet, the adhesive in liquid form being sprayed onto the back of the sheet by spray nozzles 13. The superimposed layers are fed between resilient rollers 14 and 15 which cause the foil to stretch slightly and to conform in shape to the back of the polycarbonate sheet.A lacquer is subsequently applied to the back of the foil, and the foilbacked sheet is then cut up to form units of the shapes and sizes desired. A sealing strip comprising adhesive tape or an extrusion of a plastics material, may be fitted around each unit. A backing sheet of a relatively inexpensive plastic material may be mounted behind the lacquered foil, if desired, before the sealing strip is fitted.
The units thus formed may, for example, be used as or incorporated in reflectors for vehicles, or in road signs. Letters or symbols may be applied to the front of the sheet if required.
Referring now to Figure 2 there is here shown a body 20 formed from a sheet of transparent plastics material. The front 21 of the body is roughened to prevent mirrorlike reflections, while the back is formed with pyramidal recesses similar to those in the body shown in Figure 4. A sheet of aluminium foil 22 has been adhesively secured to the back of the body 20, and has been deformed so as to enter the recesses. It will be seen, though, that the foil does not fully reach the innermost parts of the recesses. A layer of lacquer 23 has been applied to the back of the foil, and a sheet of opaque plastics material 24 is adhesively secured behind that. The margin of the assembled layers is protected by a strip 25 of protective edging material adhesively secured in position.
The material shown in Figure 3 has a roughened front face and its rear face is formed with an array of projections each in the shape of a shallow hexagonal pyramid.
The material shown in Figure 4, on the other hand, has a flat front face and its rear face is formed with an array of recesses each in the shape of a shallow square pyramid.
