Abstract

PURPOSE:To obtain the title multilayer glass plate capable of manifesting diversified patterns, by laminating plural sheets of laminated glass with transparent colored glass fused on one side of colorless transparent plate glass, on each of which different picture and denseness have been graved, followed by bonding peripherally. CONSTITUTION:Firstly, a transparent colored glass is fused on one side of a transparent colorless plate glass to produce plural sheets of laminated plate glass 11, 12, 13, 14 differing in color tone from one another. Second, different picture and denseness are graved on each of them. Thence, their peripheral parts are bonded with e.g., copper foil 15 and mutually laminated to obtain the objective painted multilayer glass plate 10. This glass plate 10, according to difference in brightness between the position of an observer and its opposite side, e.g., between indoor where the observer is located and outdoor opposite to said observer, is complicatedly combined in respect of the patterns and colors provided on said laminated glass 11, 12, 13, 14, therefore, being highly valuable in terms of art and decoration with the pictures and colors varied in a diversified fashion.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to a colorless transparent plate glass having a plurality of primary colors (2 to
5 sheets) Layered glass, which is constructed like this regarding art plate glass products with patterns and shading for each type, has a difference in brightness and darkness on the opposite side of the plate glass from the position where IJ1'II4 is located,
In other words, the patterns and colors applied to each cover glass can become complicated due to the difference in relative brightness between the side where the observer is located, such as indoors, and the opposite side of the observer, outdoors, or an adjacent room. This invention relates to a laminated glass product having an artistic pattern that, when combined, creates an extremely diverse pattern that changes like a kaleidoscope.

[Prior Art] Plate glass with only a pattern applied thereto is industrially produced as plate glass for architectural use, and is widely used for bright windows and hinged doors in homes.

In addition, the stent class, which is decorated with one color and pattern, is used as a bright window in churches, halls, etc., and is designed using a pasting method with a pattern appropriate for each location, and is then inserted into a designated position.

In stained class, the patterns and colors equivalent to a single picture are divided into small pieces and are pasted onto the base metal, either by leaving the original colored plate glass or by painting other colors on the surface. The patterns and colors of each small part remain unchanged, so although the difference in shading of the entire design changes due to the difference in brightness indoors and outdoors, it is unlikely that the entire design will change. I don't get it.

In addition, due to the construction method of the stained class, each small piece of colored glass is divided into 41.42° and 43.44° as shown in Figure 4.
．． 45, 46, etc., are connected to adjacent pieces one after another using a lead profile with an H-shaped cross section, and the lattice slag 1 for reinforcement:
48.119, etc., after completion, the opaque lead connections for these connections remain as shown in the figure, with many continuous strong black lines, giving a unique impression, and creating a unique Japanese style. It was inappropriate to express an elegant pattern that would harmonize with the space.

[Means for solving the problem] H-shaped lead for connecting each piece of colored plate glass corresponding to the part of each piece in the pasting method, which is a fatal flaw in the stained class of the prior art. It is also possible to eliminate the black outlines caused by the wood so that the colors and patterns are connected and change gradually, and it is also possible to create a pattern that changes clearly from one color pattern to another. We also provide colored plate glass that can be used as a light window, and we go one step further and, based on the person who observes or appreciates this colored plate glass, for example, use it as a colored plate glass or a light window in the room of a house. is fitted into walls such as staircases,
When the viewer is indoors and the indoor brightness changes and the outdoor brightness changes, the pattern and color that can be seen through the colored plate glass changes in a variety of ways according to the difference in brightness. If plate glass is provided, the artistic sense afforded by such clear windows is extremely attractive, and they are especially useful in halls, staircases, and partition walls between adjacent rooms in hotels, meeting halls, and museums. When used in a church or a religious organization's place of worship, it can enhance the solemn atmosphere of the place, as it attracts the attention of visitors.

According to the present invention, the colored plate glass that satisfies a high level of artistic sense and has a variety of patterns and colors changes,
This was made possible by adopting the following configuration and construction method.

In principle, it uses a subtractive color mixing method that uses the three primary colors,
Commercially available colored glass (covered) that is fused to one side of three colored glasses: yellow (Y: yellow), reddish-purple (M: macenta or wine red), and blue-green (C: cyan) It is also good to combine three pieces of glass (called plate glass), and if necessary, add R overlay plate glass to make four pieces.

In addition to the plain and transparent colored portions of such glass covers, those with patterns are also available on the market, so even if you add these, you can create a new look.

In order to express a design (pattern) on the covered glass, a pattern is engraved on the colored surface of each colored covered glass (hereinafter simply referred to as the material) according to a design by a professional artist or a design requested by the user. In that case,
The colored surface is made of fused plate glass and is hard, making it impossible to use a regular chisel.

Carved using the truss method. Mask the surface of the material with one or several layers of vinyl tape, cut the tape in the area where you want to carve the pattern, remove it, and then sandblast.

In this case, either the color engraving is removed to make the pattern appear milky white, or the outer part of the pattern is sandblasted to leave the color surface of the part that will become the pattern.

The material is transparent colored glass with a thickness of 2 to 3 wm, which is the colorless transparent part, and the fused covering part is about 0.3 to 0.511 m thick, and the depth of the carved part of the colored surface is changed by sandblasting. By doing this, it is possible to show light and shade as a satin pattern of the same color, and it is possible to give further variation to the pattern by using diffused reflection.

In this way, after carving patterns corresponding to each color of material, each board (called a unit board) is stacked together and made into a single laminated glass using Koba tape (copper foil tape) and solder. When joined, they are designed to express complex patterns. When overlapping, a smooth colorless transparent portion should be placed on both sides of the overlapping state. In addition, since the thickness of the sheets of glass becomes uneven due to decoration, especially when considering strength and safety, strengthened glass sheets are stacked on the frontmost and rearmost surfaces and bonded into one sheet.

[Function] The patterns engraved on the unit boards of each color are drawn separately in this way, and the sandblasted parts become satin-finished and can be further shaded, so that the viewer can see them from the outside to the inside. If the amount of light transmitted in the opposite direction is large,
The light that has passed through all of the unit plates creates two to four overlapping parts of each color, and the combination of each primary color creates an extremely complex pattern.

Also, areas are formed where no color overlap occurs, and these areas consist of only one primary color, or areas where the colored surface of the material is scraped off and become colorless, i.e., areas that become opaque white to the viewer. This also creates a more complex pattern due to the addition of shading. If it is dark outside and there is little amount of transmitted light from the outside and only indoor lighting is available, only the reflected light from the colored surface of the carved part of the unit board closest to the viewer will be observed, so only the innermost pattern will be observed. When the light reaches a certain level, such as at sunrise in the morning, the overlapping colors only transmit the light in the bright areas, and as the sun rises, the pattern gradually changes.

[Example] Green (clean) sheet glass is used to create an ivy pattern (IZO), yellow (yellow) is used to create ginkgo nuts, red-purple (winelet) sheet glass is used to create autumn leaves and flowers, and blue is used to create a dove pattern. FIG. 2 is an exploded perspective view showing a door lighting device in which these four unit plates are stacked and joined as shown in FIG. 1; The reference numeral 10 in the figure indicates the completed state of colored laminated glass, and the design of each unit plate is 11.12.
13.14, and numeral 15 indicates #4 foil (edge tape), and after finishing the engraving work by sandblasting on each blank board, the outer edge is coated with copper with a width of about 5 to 10cm. The foils 15 are bordered, held in an overlapping state, and joined together by melting semi-EiJ.

Code 11 is a unit plate with an ivy pattern carved on a green base plate.
+2 has a ginkgo pattern in member colors, 13 has a pattern of autumn leaves and flowers in wine red, and 14 has a pattern of autumn leaves and flowers in wine red.
is a unit plate carved with an H-colored dove pattern.

Regarding each of these unit plates, as shown in FIG. 2, 16 is a colorless transparent layer of cover glass, and 17 is a layer of green transparent cover glass. Reference numeral 18 is a colorless transparent layer 16
19 is a part carved to a predetermined thickness by sandblasting, resulting in a milky white frosted glass layer, while 19 is a dark green overlaid glass layer carved to a predetermined depth,
It is also possible to scrape away the part of the colored glass other than the pattern on the ivy pattern or abrasive glass, leaving the pattern area.

[Function] The front and back sides of the multi-panel colored glass plates constructed by stacking each other in this way, that is, the side of the viewer who is in the room, is called the front surface, and when the opposite side is the back surface, it is called the front surface. The state in which patterns and colors change according to changes in brightness (illuminance) on the back will be explained with reference to the drawings.

FIG. 3(A) shows a state in which the front side (indoor in this example) of the colored laminated glass has high illuminance, and the opposite side (outdoor) (back side) is almost dark. In this case, light does not pass through from the outside, and light such as illumination passes through the transparent layer 16 exposed on the surface of the unit board 11 and is diffusely reflected by the green ivy pattern covered inside. Only the green ivy pattern is visible to the human eye.

Figure 3 (B) shows that the outdoor (back) is used more than the indoor (front). The figure shows a case in which light can pass through only the overlapped part of the light yellow part of the light and the light color of the green ivy, and as shown in the figure, only the part through which light passes can be seen by the human eye.

FIG. 3(C) shows a case where the outside (back) is extremely bright, such as outdoors on a sunny day, the inside (front) is not so bright as normal lighting, and the illuminance from the back is high.
In such a case, the light passes through the overlapping parts of the patterns on the colored glass plates and reaches the eyes of people in the room. Therefore, even areas where the reddish-purple pattern of autumn leaves and flowers overlap with the blue pattern of doves are transmitted through, creating a fantastic pattern that visually overlaps with the dark blue-purple color.

In this explanation, I have illustrated and explained only the three types of conditions: outdoor (back), the darkest condition, an intermediate condition, and the brightest condition, as described above, and the degree of difference in brightness between indoors and outdoors is unbeatable. Because it exists, the variations in patterns and colors associated with it are realized in an almost infinite variety.

Regarding the Ichiriki pattern part, when stacked, there is a part with only a single color pattern and a part where patterns of 2 to 4 colors overlap, and when using single-ply glass as a standard, the outdoor area is on the opposite side from the viewer. When the light is sufficiently bright and the room is dark, the overlapping parts of the patterns are mixed in various colors depending on the type and number of colors in the overlapping parts, so the patterns and colors intersect in a complex manner.

For example, when the brightness in the room decreases and gradually becomes darker, such as at sunset on the 1st, areas where two or three colors overlap, such as reddish-purple or blue, become a color close to black, and 1M or lines overlap. The darkened areas also change to a darker tone, and the colors change in a variety of ways according to changes in indoor and outdoor brightness, making it possible to impress the viewer.

When it is outdoors or in near-darkness, and the only effect is the indoor lighting, the reflected light from the indoor lighting will be enough to distinguish between the part of the pattern engraved on the unit board closest to the viewer and the part of the first object. Is the reflected light from the pattern part of the second sheet transmitted through the colorless frosted glass part and the transparent part that has not been sandblasted? It is fully recognized by the whole or reflected light.

[Effect 1] As described above, according to the colored laminated glass according to the present invention,
Mainly 2 to 5 types, preferably 3 to 4 types, such as clean, yellow, wine red, and blue, are selected from commercially available covered plate glass, and these are selected according to the designer's creative sense or according to the user's request. By combining and carving a large number of patterns, an endless number of colored designs can be created even when stacked on the board, and the brightness of these stacked designs on both the inside and outside of the board surface is created. Since it changes extremely diversely depending on the size of the tree, its artistic and decorative value is extremely high.

′ Moreover, in production, on a single-colored covered glass plate,
Since it can be produced using a relatively simple method of masking it with vinyl tape and engraving a pattern using sandblasting, it can be made into an economically viable copper product.

It can also be used in places that require a magnificent atmosphere, such as domes of churches, chapels, and ceremonial halls, the middle of a single wall staircase, and clear windows on landings, as well as places that require an elegant feel, such as high-class Japanese houses and Japanese-style restaurants. extremely suitable. In addition, patterns with a modern design are carved for the entrances and exits of meeting places such as luxury apartments, restaurants, and various halls, and as partition walls from adjacent rooms.We actively use patterns and colors by using different opening degrees and spotlights. such as artificially changing the

It can be used in a wide variety of fields, including as part of building walls, interiors, and decorations, as well as in lighting fixtures with built-in dimmers, making a great contribution to industry.
