Abstract

Laminated windows are obscured in particular areas thereof by incorporation of one or more separate localised areas of obscuring compatible material in the interlayer in areas where obscuring material is required. In the construction according to the invention, areas of compatible obscurating material (13, 13') (e.g. transparent plastics material incorporating a dye or pigment) are incorporated in the interlayer material (14, 15, 16) in the window areas where obscuration is required. The invention is especially applicable to vehicle windows, for example, windscreens and destination windows for railway locomotives and cars. <IMAGE>

Description

Windows The invention relates to windows, and especially to laminated windows incorporating one or more obscuration areas.
It is well known to provide an obscuration band around all or part of the periphery of a vehicle window, both for cosmetic purposes and in order to protect an adhesive used to glaze the window from exposure to uv radiation and consequent degradation.
Such obscuration bands are usually produced by printing with a black ink comprising a glass frit on a glass pane before it is bent and, if appropriate, toughened, so that the ink becomes fired into the glass surface providing a durable obscuring layer. However, we have found that printing of the black obscuration bands may have deleterious affects on the production and performance of laminated windows. Thus, the presence of black bands around the edge of the glass results in difficulties in maintaining accurate peripheral shape when shaping windscreens of complex shape.Furthermore, the presence of fired ceramic ink obscuration bands tends to reduce the strength of the glass in the area(s) of the bands, increasing the risk of premature breaking (on fitting or in service) as a result of edge deflections consequent on slight discrepancies in shape between the window and the glazing frame.
The present invention seeks to solve the problem of providing durable obscuration areas on laminated windows while achieving improved processing and serviceable life.
We have discovered that this may be done by incorporating separate localised areas of obscuring compatible material, conveniently plastics material, in the areas where obscuration is required, in the transparent interlayer material used to form the laminated.
According to the present invention there is provided a laminated window in which one or more separate localised areas of obscuring compatible material is or are incorporated in the interlayer in areas where obscuration is required. The obscuring compatible material will generally be a transparent plastics material incorporating a coloured dye or pigment to render it obscuring and, usually but not necessarily, substantially opaque at least in the visible region of the spectrum.
The term "compatible" in the expression "compatible material" is used to refer to materials which do not interact deleteriously with the material of the interlayer they contact to an unacceptable extent, and are satisfactorily stable during the production of the window and its subsequent use. An obscuring compatible plastics material for use in the invention is conveniently (but not necessarily) of the same general chemical nature (e.g. polyurethane or polyvinylbutyral) as the surrounding interlayer material in which it is incorporated, but if it is thermoplastic preferably has a higher softening point so that the obscuring component present is not carried into the surrounding interlayer material on lamination.In practice, it is desirable that an obscuring compatible plastics material has a softening point at least iO0C above the softening point of the abutting interlayer material which will usually be transparent.
According to a further aspect of the present invention, there is provided a method of producing a laminated window having one or more obscure areas comprising providing inner and outer panes for the laminate, a separate section or sections of compatible obscuring material corresponding to the areas which are to be obscure in the finished laminated, and a complementary area or areas of transparent interlayer material, assembling the said components with the obscuring material and transparent interlayer material between the panes, and subjecting the assembly so produced to a laminating process.
The components are preferably selected and the laminating process carried out at a temperature such that the transparent interlayer material, but not the obscuring material, softens during lamination.
The transparent interlayer material used in the practice of the present invention will usually, but not necessarily, be a conventional interlayer material such as polyvinylbutyral or polyurethane. The term "transparent" is used to indicate the properties of the interlayer material in the finished laminate; it does not mean that the interlayer material is necessarily transparent in the unlaminated state.
The invention is illustrated but not limited by the following description with reference to the accompanying drawings in which: Figure 1 is a rear (ie from the interior of a vehicle) elevation of a laminated window in accordance with the invention.
Figure 2 is an exploded schematic view of a section through the window of Figure 1 along the line 11-11.
Figure 3 is a rear elevation of a second laminated window according to the invention showing an alternative arrangement of obscuring areas.
Referring to Figure 1, a driver's window for a railway locomotive generally designated 1 comprises a clear central vision area 2 and a peripheral obscuration band 3. The construction of the window shown in Figure 1 is apparent from Figure 2, which shows inner and outer translucent panes 11 and 12, sections of compatible obscuring material 13 and 13' corresponding to the upper and lower strips of the obscuration band 3 shown in Figure 1, a complementary area of interlayer material 14 and additional inner and outer layers of interlayer material 15 and 16.
To produce the laminated locomotive window of Figures 1 and 2, a frame corresponding to obscuration band 3 and including upper and lower strips as shown in Figure 2 joined by side strips was cut from a 1.25 mm thick sheet of obscuring thermoplastic polyurethane designated "PE 192 black" (polyurethane sheets of the PE series are available in commerce from Morton Thiokol Inc of Chicago, Illinois, USA), having a softening point of 125"C. A complementary area, corresponding in shape and dimensions to the interior of the frame was cut from a 1.25 mm thick sheet of clear thermoplastic polyurethane designated "PE 193", and having a softening point of 110 C .
Components for inner and outer layers 15 and 16 of interlayer material were then cut from 1.25 mm thick PE 193, each of the inner and outer layers comprising 3 plies of the polyurethane material so that each of said layers would have, on assembly, a thickness of 3.75 mm. Finally, panes of clear float glass 5 mm and 4 mm thick respectively were cut to size, bent and annealed to provide inner and outer panes of the laminate.
The internal faces of the glass panes (i.e. the faces which were to abut the interlayer in use) were spray primed with 5% AllO0/methylated spirits (A1100 is a commercially available aminosilane adhesion promoter), the components assembled as shown in Figure 2 with the panes generally horizontal, and excess interlayer trimmed from around the edge of the assembly so formed.
Silicone rubber tooling was then taped around the assembly with PTFE tape, sheets of interleaving paper placed on each side of the assembly and the assembly with interleaving paper placed in a polypropylene/melinex bag which was evacuated for one hour.
The resultant assembly, in the evacuated polypropylene/melinex bag, was placed in an autoclave and heated at 115"C-120"C for 2 hours at 6 bars pressure.
After autoclaving, the laminate was allowed to cool, removed from the bag, and the tooling removed to provide the laminated window shown in Figure 1 ready for installation and use. Because the lamination was carried out below the softening point of the obscuring polyurethane PE 192 black, the edges of the resultant black obscuration band remained clear and well-defined, with the product being substantially indistinguishable in appearance in service (except on close examination) from the corresponding prior art product with the obscuration band printed on the inner glass pane.
In addition to avoiding the need to print the glass, the present invention not only allows for better shape control during glass forming (especially when forming complex shapes) but also avoids the weakening effect on the glass associated with fired ceramic inks allowing greater tolerances in matching between the window and the glazing frame and providing a longer prospective service life when an exact match is not achieved.
The invention may be used not only when an obscuration band at the periphery of the window is required, but also in the production of other windows with obscure areas, as shown, for example, in Figure 3. This figure shows a destination window 1 for a railway car which, like the driver's window of Figures 1 and 2 has a peripheral obscuration band 3'; in addition, it has an opaque destination board area 30, which bisects the clear vision area into upper and lower parts, 2'a and 2'b.Such a window may be constructed in the same way as described hereinabove with reference to Figures 1 and 2, but with an insert of black polyurethane used across the central area, with the complementary area of transparent interlayer, within the frame formed to provide an obscuration band, divided into two separate smaller pieces corresponding to 2'a and 2'b of appropriately reduced (to allow for the insert) size.
It will be appreciated that, while in the construction specifically described above, the obscuring material was (a) substantially opaque and (b) sandwiched between transparent plastics interlayer material on both sides, neither of these features is essential to the invention. Thus, for example, while the invention is primarily intended for use when an area of substantial opacity (i.e. less than 2 light transmission) is required, it may also be used in producing an obscuring area which still has significant, say up to 50%, light transmission e.g. the "shade band" areas of laminated car windscreens which have a light transmission in the range of 5 to 25% and are designed to protect the driver's eyes from bright sunlight, especially when the sun is low in the sky.Again, the invention may be used with an obscuring layer of interlayer compatible material sandwiched directly between outer glass panes, abutting transparent interlayer material only at its edges.
It will further be appreciated that while the invention is most advantageous when applied to complex curved windows, it may also be used for the production of laminated flat windows. Moreover, while the foregoing description has concentrated on the application of the invention to simple laminates i.e. laminates with two panes laminated together with a single interlayer, it may also be used in the production of more complex laminates comprising (n) panes laminated together with (n-1) interlayers; in this events the obscuring compatible material may be incorporated in more than one interlayer, although it will generally be sufficient, and most convenient, to incorporate it in a single interlayer.
