Abstract

A laminate is provided which comprises two sheets of material e.g. glass bonded to respective major surfaces of a central plastics sheet, wherein said central sheet has a decorative feature extending over at least a portion thereof, and wherein each sheet is made of a material such that it transmits light. The laminate finds particular use in the field of imitation stained glass windows.

Description

SPECIFICATION A decorative laminate and a method of producing such This invention relates to a decorative laminate and a method of making such, and more particularly to a pane of such material when used for decorative purposes, e.g. as an imitation stained glass window.
Up until the present time, imitation stained glass windows have been produced by the manual application of specially prepared paints onto a pane of glass to form a decorative pattern. Strips of lead are then applied to the surface of the pane where paints of different colours border one another. The pane is then generally attached to a further pane of plain glass, such that the painted surface is sealed within the finished unit. This ensures that the paint is not exposed to the elements which would otherwise deteriorate it.
Up until now, therefore, such laminates have been the subject of lengthy and expensive production, due to their labour intensive manufacture.
Thus there is a need for a much simplified process resulting in a more versatile and less expensive product.
According to one aspect of the present invention there is provided a laminate comprising two sheets of material bonded to respective major surfaces of a central plastic sheet, wherein said central sheet has a decorative feature extending over at least a portion thereof, and wherein each sheet is made of a material such that it transmits light.
According to two further aspects of the present invention, there are provided both an imitation stained glass window and a double glazed-unit each comprising such a laminate.
In a further embodiment of the present invention, there is provided a method of producing a decorative laminate comprising the steps of: 1. forming a decorative pattern on a plastics sheet capable of transmitting light; and 2. sandwiching the sheet of plastics between two further sheets of material each capable of transmitting light by bonding the sheets together with resin.
In one aspect of this embodiment, the laminate is cut into at least two separate pieces by a method comprising the steps of: 1. scoring the outer two sheets of material to define at least one area of laminate of a predetermined size; 2. pulling the outer two sheets apart at the score lines to expose a small area of the plastics sheet; and 3. cleaving the exposed area of the plastics sheet so as to separate the at least one area of laminate of a predetermined size.
The laminate thus prepared to a predetermined size may then be used as a decorative laminate in, for example, a stained glass window.
In the drawing: Figure 1 is a side view of the laminate of the present invention.
An embodiment of the invention will now be described with reference to Figure 1, which indicates a laminate generally at 5 which comprises a central plastics sheet 30, sandwiched between two further sheets of material 10,20. These sheets are bonded together at junctions 15 with an adhesive.
The central plastics sheet is a glass clear, polished both sides, acetate film. It is generally about 125FLm thick, though this can vary depending upon the use of the laminate. The film should be extensible for reasons which will be described later. The laminate of the present invention can also comprise other types of plastics sheet which have similar characteristics.
The plastics film includes a decorative feature 25.
This is generally a coloured coating on the surface of the film, produced by a silk screen process.
Such a process is already successfully applied to films of this nature and is well known in the art.
The coating generally includes a plurality of different colours which may be applied in a succession of printing steps, such that the final laminate appears multi-coloured.
The decorative feature may also be coated over both surfaces of the plastics sheet, or in some circumstances, be formed integrally with the sheet during its manufacture by for instance a moulding, extrusion or similar process.
The outer two sheets 10,20, are chosen from materials which transmit light such as glass or certain plastics materials. Each sheet generally has a thickness of from 2 to 6 mm, though this can vary depending upon the use of the laminate.
The outer two sheets are bonded to the central plastics sheet by applying a glass clear resin to either the two faces of the central plastics sheet or to one face of each of the outer two sheets and then brining the sheets comprising the laminate together so as to allow the resin to bond the laminate together. It is preferred that the sheets are brought together in such a way that air bubbles are removed from the junctions of the various sheets so as to ensure the clarity of the finished laminate. The resin is allowed to set ensuring that the laminate does not dissociate during use.
The laminate of the present invention finds application where decorative panes are required, such as in the field of imitation stained glass, shelving, and tops for such articles as coffee tables. The materials forming the laminate are chosen for their ability to transmit light. Thus if the laminate is mounted to allow light to pass through it, the laminate will be seen to include the decorative feature giving the impression of it being a pane of stained glass. This effect can be enhanced, if during the printing process, darkish or black lines are printed or painted at the junctions of different colours so as to give the impression that each area of colour is a separate piece of glass mounted in a lead frame as is usual in stained glass windows.
The laminate thus formed may be used as part of a double glazed unit thus providing both an attractive and energy saving window.
The laminates of the present invention can be manufactured to any required size. Thus they may be produced in sizes specifically for use in commercially available window frames. Alternatively, the laminates can be produced in any standard commercial size in which panes of glass are currently produced. Such laminates may then be cut to a predetermined smaller size which is commercially useful e.g. to a size useful for windows or their replacement or for shelving. Such cutting can be done in the case of volume production by a laminate power saw. Alternatively, the cutting can be carried out by firstly scoring the outer two sheets to define at least one piece of laminate of a required size. The laminate is then pulled apart along the score lines to expose a small area of the central plastics sheet. It is preferable therefore that the plastics sheet be extensible.The plastics sheet is then cleaved at the exposed area by either slitting it with a blade or by melting it. The melting may be carried out by burning (e.g. with methylated spirits or a butane flame) or by ignition of the film.
If suitable material is chosen for the outer two sheets, the laminate of the present invention may be used as safety glass.
The laminate might also be used in place of the glass panels often used in doors.
If the decorative feature extends across the entire area of the plastics sheet, and is produced by pigments which absorb much of the light falling on them, then vision through the laminate will be obscured. Such laminates may be used in bathrooms or toilet windows which up up till now, have been generally patterned frosted glass (i.e. glass white).
The present invention also includes within its scope laminates wherein the decorative feature includes at least one portion which does not transmit light. Such a portion may be obtained by the use of a pigment which absorbs substantially all light falling on it. Such portions may add to the decorative effect produced by the laminate, in that they will produce opaque regions which may be used to create a pleasing patterned effect.
