Description

Detailed Description of the Invention

FIELD OF THE INVENTION The present invention relates to a glass facing plate, which is made at least in part of a transparent material, preferably of glass, which plate has a coloring effect based on optical phenomena. It has a pattern or an image to have.

BACKGROUND OF THE INVENTION For example, light reflected by a matte or glossy surface causes the reflective surface of the material to pass through the reflective surface of the material after it has passed through some surface structure layer or the entire structure with a mirror on the back surface. It is known that the light finally reflected by the provided object creates a pattern or image characterized by a distinctive or distinctive light effect.

It is also known to produce colored decorative patterns that exhibit the effect of a rainbow caused by light passing through the system of transparent material and optical layer, where the resulting patterns vary depending on the illumination and the viewing angle. become.

Illuminating each component with a surface relief consisting of a series of traces formed of a planar or relief structure, and with a given illumination and a given viewing angle 1
It is also known to create a hidden decorative pattern that provides a coloring effect by exhibiting the diffraction effect of light when creating the above image.

Furthermore, it is possible to illuminate rasters placed on top of each other, one of them being an image raster and the other one of a reference, eg a character, whereby they result in a composite image and / or Alternatively, it is known to create various or hidden decorative patterns that exhibit a coloring effect by forming letters. These rasters are formed by a film with a large number of irregular, opaque, dark image elements (reference raster) and a film with a large number of dark or colored image elements on a light colored pigmented base. To be done.

Another known solution is a transparent or translucent plate-like component,
A variegated visual angle-dependent evoked decorative pattern of objects, each comprising two rasters next to each other, arranged next to each other on one of the opposing surfaces of this component. The resulting tissue utilizes the interference of light to produce the resulting tissue of predetermined lines, the so-called moire effect.

[0007] Two smaller series of geometrically coupled motifs whereby the image of the first series of motifs is visible when illuminated in the dark with light in the invisible spectrum, Decorative elements are also disclosed, including those in which when illuminated with light in the visible spectrum, an image of another series of motifs different from that of the first series becomes visible.

It has also been disclosed to create a special image with light passing through a transparent material comprising a patterned layer, which is ultimately colored.

Czech Republic 274 488 discloses decoration in the form of a relief pattern on a plate of organic or inorganic glass. The back surface of this glass plate is decorated with a raster composed of optical elements, the surface of which is due to the negative image of the raster expanded or reduced within the range of 0 to 15%, or the raster of the back surface. Decorated by different different rasters, the optical overlap of both rasters with each other creates a three-dimensional pattern forming a three-dimensional glass decoration. The above elements can consist of lines or circles and the like.
To enhance the effect, it is possible, for example, to provide a paint layer on the back of the glass, or optionally opal glass to combine the three-dimensional decoration with the usual flat print or another traditional decoration technique. Is.

Decorative elements are also known in which the raster is of a crossed filament composed of a substrate with a reflective surface having a fixed raster. In this case, the pattern is created by the reflected light and depends on the viewing angle.

All of the above-mentioned solutions are of satisfactory quality, with a light effect created on at least partially transparent and hard material, for example glass, in one arrangement of the optical environment, It does not make it possible to create a large number of patterns that are made in different ways and are reasonably priced.

SUMMARY OF THE INVENTION The present invention creates a variety of decorative patterns and coloring effects in a simple manner by optical phenomena on at least partially transparent and hard materials, preferably glass. Enable

The object of the present invention is to arrange the tissue of the formation.
em) a decorative element with a pattern or image created by the light effect utilizing the passage of light through a plate-like material, eg glass, preferably with glass, this element having its back surface Side and front side prints, and including this on at least a portion of the back side and front side surfaces of the plate, the element being in the form of a plate of predetermined thickness. , The applied print consists of a surface raster consisting of characters formed into groups with parallel lines and slits and slits between them, said configuration of said back print and said front print slit The number of objects is different, and the predominant direction of the back print formation is more than 50% identical to the direction of the slit of the front print. A.

[0014]   Preferably, the decorative element plate is 1 to 25 mm thick.

Furthermore, when the print on the front side is formed by the organization of parallel lines and slits, ie by the line raster, and the print on the back side is organized by the organization of characters grouped into lines separated by slits. It is preferably formed.

Also, when the print on the front side is formed by the organization of parallel lines and slits, ie by a line raster, and the print on the back side is grouped into formations with the form of lines with slits between them. It is also preferable if it is formed by the organization of the character.

The solution according to the invention makes it possible to create a decorative pattern on a hard material, for example glass etc., with a quality that cannot be achieved when using conventional decorative techniques, and The present invention is relatively simple to implement and reasonably priced for a wide range of applications. The printed material is very abrasion resistant when using baked colorants and glass cullet. They therefore offer the possibility of using the resulting products as, for example, decorative tiles. This technical solution also makes it possible in a simple manner to mimic so-called metallic pigments with copper, silver or gold and other shades. The desired shade depends only on choosing the right combination of optical methods used in the production of the decorative pattern.

Furthermore, it is advantageous if the direction of the print formations on the back side of the plate is inclined from more than 50% of the same predominant direction of the formations up to 30 degrees. By this measure, the local decoration exerted by the surface decoration being substantially shining or darkening it, where it can be used to represent shadows and light on the depicted object, It is possible to create more or less differentiated maximum and minimum points of interference.

Hereinafter, embodiments of the glass decorative plate according to the present invention will be described with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION The special patterns and color effects according to the present invention are based on optical phenomena such as diffraction, interference, scattering, reflection of light rays, and with respect to the viewing angle, the plate-like material described above. It is obtained by mutually exposing or covering corresponding points of the prints applied on the front side and the back side of the.

As can be seen in FIG. 4, the material used to obtain the effect according to the invention is a plate 1 of at least partially transparent material, for example glass, which has a thickness t. Have. The plate 1 includes a front side 3 and a back side 2. These two-sided sides 2 and 3 are provided with a printed pattern in the form of a flat line raster, or a raster with the characters grouped into formations in the form of lines and slits, which Thus, the preferential direction of the slits of the print on the back side 2 is in the range where more than 50% is the same as the direction of the slits of the print made on the front side 3, as is clear in FIGS. 1a and 1b. is there. FIG. 4 shows the points marked A on the front print and the points marked B and C on the back print.
It is clear that as the viewing angle is changed, and depending on the thickness t of the material used, the cooperating points of both change. When the viewing angle on the front side 3 is 90 degrees, the light conditions at the points A and B cooperate with each other, but the viewing angle is changed by the angle α, and when the viewing angle on the front side 3 becomes 90 degrees + α, A The light conditions at points C and C work together. Therefore, the changes we see are observed.

The above-mentioned optical phenomena used to achieve the pattern and color effect can be applied individually or in cooperation with each other.

For example, a print on the front side 3 of the plate 1 is formed which will create diffractive apertures or gaps, ie interfaces between the various optical environments, whereby the rays of light passing through are different optics. Utilizes diffraction, scattering, and interference so that they are bent at a density boundary, partially decomposed into individual spectral colors, and in their further optical path they interfere as they approach each other. It is possible. At this time, the location of the bright or dark interference in the print on the back side 2 affects the resulting brightness of the print on both sides 2 and 3. Diffraction openings can be created, for example, by removing a portion of the preprinted surface with a laser gun,
Or by a special printing procedure or, in the simplest way, by mixing transparent particles of a size corresponding to the thickness of the print, for example crushed glass or ice flake particles, into the printing ink according to the graphic design be able to. The method of making the diffractive aperture can have some effect on the splitting of the spectrum of the light. The strongest effect is obtained by using shattered glass, since it leads to multiple diffractions, thereby contributing to a stronger spectral splitting.

According to the invention, a light beam can be reflected, for example by means of a print applied to the back side 2 of the plate 1 using inks of different ability to reflect light, whereby a mirror surface is formed. It However, it is also possible to use a mixture of the ink and a crushed transparent material, such as crushed glass, which forms both a mirror surface and a heat-resistant interface in the crystalline system. Such a heat resistant interface can split the incoming light rays or partially interfere. In this case, the above-mentioned reflective or combined reflective effect varies both with the viewing angle and the transparency of the individual points of the front side 3 print.

The mutual exposure and concealment of each point can be achieved as follows, for example. When the prints are provided on both sides 2 and 3 of the plate 1 and the front side 3 is at least partially transparent in various places according to the desired graphic design, the color of the plate 1 will always be the individual print of the back side 2. Depends on the light condition of the point, ie front side 2
And the effects of the individual colored portions on the back side 3 are simultaneously configured. For individual points located next to each other, for example in terms of color or brightness, where the prints on the back side 2 have different light conditions, the colors on the front side 3 and the back side 2 change simultaneously as the viewing angle changes. , Which also changes their combined effect. this,
For example, a predetermined relative arrangement of dots, such as a pattern, can be made available in a predetermined color only when viewed from a particular angle. The pattern disappears or changes its color when the viewing angle is changed.

The solution described above affects the pattern and color system. The use of printed baking ink and shattered glass makes the printed material very abrasion resistant. It's stable, rather simple, and reasonably priced.
This is the advantage of this solution. The plate according to the invention can easily mimic so-called metallic pigments, such as, for example, copper, silver, gold and the like.

A concrete application product of the present invention is represented by a glass tile. Such tiles can have a side length of 1 to 200 cm and a thickness of 1 to 25 mm, and the shape of the tile can be rectangular, square, polygonal or other. In the simplest case, as shown in FIG. 1a, the tile is of the front side 3 using a pattern of narrow slits 4, substantially represented by parallel lines printed with abrasion-resistant ink. Covered by print. The wire has a thickness of 0.1 to 2 mm and a pitch of 0.1 to 1.5 mm. The general rule is that the smaller the size, the better the quality. However, the dimensions defined above are sufficient to obtain the expected effect. The back side 2 used to attach the tiles to the wall is shown in FIG.
A print-coated or print-covered film is adhered to the entire surface as a light-colored substrate, as shown in b, and the disordered formation of the character 5 is printed on this substrate, of which 50 % More than is in the same direction as the texture of the slits 4 on the front side 3 (forms a row), or the predominant direction of printing is substantially parallel to the direction of the print slits 4 on the front side 3. To be. In this way one state is obtained when the rays are refracted in the narrow slit 4 and when they enter through the at least partially transparent glass on the print on the back side 2 the different optical environment. Additional refraction and interference occurs at the interface of the. Mutual light effects between the slits 4 and the print formations 5 on the back side cause color changes and interferences, resulting in an unusual brightness of the prints on the front side 3 and the print layer is different in another technique. Win color changes that you can't get.

By not maintaining the above conditions for the condition that the two directions are parallel up to a range of more than 50% and the direction of the slit is locally tilted up to an angle of up to 30 degrees, locally different characteristics can be achieved. It is also possible to create. At this time, the minimum point (minima) and maximum point (
maxima) is obtained. In such places, they can be effectively used to provide a decorative pattern that is shown in light or shade, by virtue of the substantially increased brightness of the surface print, or vice versa. Obtained by their stronger darkness.

[0029]   2a-2c show such an embodiment.

In this tile, the print layers arranged in four quadrants of the reference circle on both the back side and the front side have reference circles with + y and + x coordinates, as will be described later. A quadrant of, ie the upper left quadrant, is printed on both the back and front. Both the diameter of the reference circle and the number of slits are proportional only to the size of the tile.

In this example, the radius of the reference circle is 27 mm. The back side 2 of this tile is provided with a print consisting of the texture of the character 7 in the shape of a curve, see FIG.
, Their total number is 34. The front side 3 is provided with a print consisting of the texture of the slits 6 seen in Figure 2b, the total number of which is 27.
When combined together, both tissues form a mutually shifted interfering network with its maximum at the intersection of the character 7 and the slit 6. As can be seen in Fig. 2c, the above maxima are less dense in the third one located in the center of the reference circle, and their intersections are a few degrees relative to the axis of the reference circle. It has a shape that approaches the shape of a line inclined downward only at an angle. On the other hand, in the third located around the circle, the points of maximum interference are dense and their intersections form a circle with a radius larger than that of the reference circle. If such a texture is realized as a print on the diametrically opposite side of a flat glass plate, an interference phenomenon is caused as a result of the difference in the number of characters 7 and slits 6 and the effect of the thin slits 6 on the interference of the rays. The result of this is the effect of the pattern color, especially if the other quadrants of the reference circle are also arranged in this way.

Other similar arrangements of maximum and minimum points of interference to obtain the required pattern and color effects are possible. One such sequence is shown in Figures 3a-3c. Back side 2
Are covered by a print consisting of the texture of the character 9 in the form of a sloping curved line. The front side 3 is provided with a print consisting of a texture of parallel slits 8. When they are assembled, they result in a minimum and maximum point texture, which corresponds to another color pattern, as shown in FIG. 3c.

Various other possibilities of the patterns obtainable according to the invention are shown in FIGS.
5i. Various geometric patterns on the surface where the brightness of one or more colors changes
Obviously, such patterns of three-dimensional nature, decorative patterns, or patterns with image motifs can also be obtained.

INDUSTRIAL APPLICATION The invention has a wide range of applications for producing hard materials, preferably glass materials, covered with applied prints. A wide variety of patterns and colors can be obtained in a rather simple way, which allows for a reasonable price. Therefore, such products can be widely used as decorative tiles.
