Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to panels, particularly transparent or translucent panels.

In this specification, the term "transparent panel" refers to a sheet of transparent material, a laminate of transparent material, or a combination of transparent materials. It is intended to include flexible materials such as polyester films or polyvinyl chloride films, as well as transparent panels that produce blurred or curved images. Similarly, the term "translucent panel" refers to sheets of translucent material, laminates of translucent materials such as glass or plastics such as acrylic sheets or polycarbonate sheets, as well as polyester films, polyvinyl chloride films, paper, It also includes fibers and materials similar to these.

Providing an opaque pattern on the surface or inside of a transparent panel to allow viewing from one direction is a construction technique for squash with transparent 4f walls. 'C known. These panels contain a continuously formed opaque pattern of a single color. Alternatively, these panels may be modified to emphasize the unidirectional vision effect, where one side of the panel (one side of the panel) is illuminated more intensely than the other side (one-way vision effect). It looks like the color is put on from one side,
From the other side it is accompanied by a pattern that appears in other colors. Single-color patterns are usually solid or light-colored, and two-color patterns are white or light-colored on one side of the panel and D! on the other. 1 is exactly or almost exactly (approximately black or a matching color applied thereto. This enhances the clarity of the perspective from the other side to the one side. In this way By using a panel material, spectators or television cameras can see through the squash court from one side, even though players can only see through the panel material from one side to the other side. be able to.

The pattern on such panels is usually drawn with small dots.

The points depicted are such that each addition to Element 1 of the pattern is indistinguishable to the eye of a spectator in the audience at a certain distance from the panel. That is, the point required for Niremen 1 is a small one that exceeds the eye's V11-ability.

Easy! The 4i translucent panel has an opaque pattern formed by placing a 1 mm diameter dot in the center of a 1.4 mm square that is white when viewed from one side. It looks black from the other side, and the other side is 5.3i < ! than the one side. ICi will be explained. The white light is illuminated by the light 4J and scattered. This prevents viewing from one side to the other. However, the perspective from the other side 1j to the one side through the panel is almost clearly 1iI
It will be done. The intensity of the light of the image 8 (J decreases depending on the degree of opacity, and unlike a colored transparent panel, the intensity of light of the image decreases or 1~~ tone down).

According to one embodiment of the invention, a colorless or light colored sheet + A fl and a pattern that is visible from one side and not visible from the other side, the pattern is a silhouette pattern (hereinafter referred to as A panel applied over or as part of (described) is provided.

A number of different vision effects can be obtained with various panels within such a range. That is, while allowing clear visibility from one side to the other across the entire panel,
Clear visibility from one side of the panel to the other can be maintained, except for areas covered by the design.

Further, it is possible to completely block the view from one side to the other side while allowing the whole panel to see through from the other side to the other side. In other words, a unidirectional perspective effect (unidirectional vision effect) can be obtained. It is possible to allow clear perspective from one side to the other, except in a designed portion, while totally or partially blocking the perspective from the other side to the other side. It is possible to completely block the view from both sides.

In any case, each side of a panel is It becomes possible to have excellent vision from.

According to the Hakunoji/Jl aspect of the present invention, the first de-1f in can only be viewed from one side of the panel and cannot be viewed from the other side, and the first design can only be viewed from the other side. The second design is visible from the side (part) or (not), and each design is formed on top of a silhouette (described below) or forms part of a silhouette pattern (described below). A transparent or translucent panel material is provided.

An example of the visual effect obtained from this second embodiment is that it is possible to clearly see through from one side to the other except for the parts that have been replaced with the first design, and the second f #f
In this case, it is necessary to be able to see clearly from one side to the other, excluding the covered parts. The effect of the block on the perspective of the panel is that the perspective from one side to the other is totally or partially obstructed, and the perspective from the other side to the other side is totally or partially obstructed. There is such a thing as being even touched by something. Further examples of effects on the perspective of a panel include: perspective from one side to the other, or totally or partially obstructed, except for the part covered by the second design; It is possible to obtain a clear perspective from one side to the other. When the intensity of the illumination light perceived through the panel from the other side of the panel is stronger than the illumination light reflected on this side of the panel,
In either case, viewing from each side of the panel is possible.

The panel according to the invention and/or the design provided on the panel is illuminated so that the visual field is focused on the design on the panel or through the panel and on the object beyond the panel. I can do it. If the illumination light perceived through the panel from the other side of the panel is applied to this side of the panel,
In the case of strong enough tosaku, soil, and irire, 1 go, j-3
11) It is possible to see through each side of the panel without being aware of the colors of the sills and/or sills. 1 - On the side where the pattern is normally visible, the level of illumination light reaching through the panel from the other side of the panel increases.
The terry-in and/or silhouette pattern is λ1
The panel according to the present invention also has the advantage of having a J-3 display on one or both sides of the panel for decoration and/or information. The panel according to the invention can be used for applications such as buildings, etc., without unduly affecting the visibility to the outside. , making it possible to control the transmission of solar heat, bright light or ultraviolet light in a vehicle or other accommodation or shelter.

According to the invention, it is possible to provide natural or artificial lighting from one side to the other side.

For example, even if an advertising board made of the panels of the present invention is placed in front of a building, sunlight can be received through the windows and the sunlight can be seen through the windows, and the outside of the building can be seen.

The design on the panel according to the invention forms or is superimposed on a pattern of opaque elements.

This pattern is hereinafter referred to as a silhouette pattern. "Siluela [-pattern"] used below
The term refers to all instances in which opaque material is placed on a panel so as to divide the panel into opaque areas and/or transparent or translucent areas. Silera [-The pattern can take many forms. For example, certain geometric elements arranged regularly, certain geometric elements arranged irregularly, elements of arbitrary shapes arranged regularly, elements of arbitrary shapes. Elements arranged irregularly or with certain elements and arbitrary shapes 1- or regularly and/or
'or irregularly arranged pieces can be combined. Continuous) 8 light parts with many phases! Instead of providing 4 separated elmmen 1-, transparent elmmen 1 separated into phases q, like a net 1~, a hat or a mesh pattern.
A sill pattern is formed to form a portion and a continuous opaque element portion.

If necessary, the silhouette pattern can also be a combination of continuous opaque element parts 1 to 1 and q-separated T element parts. All of the silhouette patterns mentioned above may be repeated on a single panel forming a large area, or may be placed repeatedly on each small panel when a larger panel is formed by a collection of smaller panels, such as tiles. It's okay.

The elements forming the silhouette pattern are preferably of equal size and arranged in a regular grid, usually small dots, referred to in the printing industry as a halftone. In some cases, particularly where transparency is required, silhouette patterns composed of separate elements may be silhouettes formed as continuous or interconnected opaque parts arranged in a 1-1 grid or a mesh. Preferable to pattern. Visually, it is easier to see through a region in which dot- or disk-shaped mutually separated opaque elements 1~ are regularly arranged than through a transparent region surrounded by grid-like opaque elements. Seems to be excellent. In this case the edge area of both opaque parts is equal. This means that the cross-section that scatters light forward in the opaque dots or discs is similar to that of the continuous thread or linear opaque parts forming the grid. This is thought to be because it is larger than the cross section.Light causes diffraction around an opaque obstacle, but if the obstacle is disc-shaped, a uniform optical path length can be obtained around it; The visual effect of a silhouette pattern is approximately the same as that of a diffraction grating. Numbness can be measured or evaluated by the same method.

Problems with the resolution of the eye when viewing fine pattern components from a certain distance, and problems with cognitive ability, where it is easier to recognize lines or grid-like shapes than to recognize discrete elements such as dots. Understand physiological problems.

The easier it is to recognize a pattern, the more difficult it is to perceive an object through that pattern.

If the silhouette pattern is formed of a grid or other continuous linear pattern and is easily recognized, it gives a psychologically more unpleasant impression than a silhouette pattern of discrete elements such as dots. This is likely because grids and other patterns involve detention or restraint.

It is easier to form a syllabary pattern of mutually separated elements in two opaque materials than to form a lattice of two overlapping opaque materials.

Elements of the silhouette pattern may be formed to cover or cover letters, numbers or groups thereof;
It can form a design or part thereof as a printed component, such as a dot matrix of letters or numbers. This results in fairly sketchy written or numerical information being visible from one side and a uniform or irregular design being visible from the other side. By decreasing the size of each element and/or increasing the distance between each element, the pattern is gradually changed or toned down. This may be useful, for example, if it is desired to vary the sunlight glare or sunlight acceptance limitations in buildings or automobiles. This type of change may be clearly provided on both sides of the panel, and may be offset by 92 on one side of the panel. For example, the white drums 1 on the outside of the panel are made of the same size so that they look uniform or almost uniform when viewed from the outside,
The inner black larger dots on the back can be arranged in the same grid pattern and vary in size. This is used, for example, to provide progressive protection against sunlight glare in the windscreen of a motor vehicle, such that the black dot is larger in the upper part of the windscreen than in the lower part. Conversely, having larger black dots at the bottom of the panel will help draw more light from the lower winter sun through the top of the panel. You can install an awning outside to block the light from the high summer sun.

A pattern of bright colors or reflective material on the outside of the panel is designed primarily to provide visibility in one direction, but a dark pattern on the inside of the panel that overlaps this pattern helps prevent heat from the sun. can have the effect of absorbing The silhouette pattern can be provided on more than one side of the overcoat to the panel or assembly with other panels, such as a multi-sided laminate, to better control the visibility through the panel. ,as well as/
Or solar heat transmission, glare or ultraviolet radiation reduction can be better controlled. Two or more combined silhouette patterns can be provided to obtain special visual effects with overlapping patterns. For example, if a silhouette pattern is a pattern of horizontal lines on two parallel planes separated from each other, the visibility seen through the two patterns will change depending on the angle of view with respect to these patterns. do. Two Silera 1-
If the patterns are equally spaced and arranged in a manner that provides good visibility from all directions, for example, the Silera 1-pattern is formed on the outside of the window, approximately matching the pattern to the Silera 1 extending in the horizontal direction. In this case, it will appropriately shield the heat, glare, and ultraviolet rays of sunlight that enters from above the horizontal direction, and will not have a significant effect on the visibility in the horizontal direction. A particularly advantageous use of this arrangement is in motor vehicle rear windows, which are normally tilted. If a linear silhouette pattern on two surfaces is provided in the horizontal direction and approximately coincides with the height of the driver's head or the position of the rearview mirror, a similar pattern is provided on one surface. Extremely large awnings are more effective than those provided only in the area. This pattern can be provided to be relatively adjustable. For example, a panel may be slidable along the plane of the panel, allowing visibility from both sides of the panel assembly to be controlled for any viewing angle.

The silhouette pattern can be relatively adjustable in one or more directions. For example, when a panel assembly includes multiple panels and each panel has a silhouette pattern, one panel may move along the plane of the panel and in a direction perpendicular to the other panels. I can do it. This allows for a wide range of solar control, ranging from total occlusion of solar rays passing through the 7-piece assembly while maintaining transparency of the assembly, and almost complete occlusion of visibility from both sides of the assembly at any viewing angle. It is possible to control a wide range of transparency including The degree of solar shading provided by two or more patterned panels may be controlled manually or by automatic devices. Automatic control can be temperature responsive or solar dependent.

The pattern formed on two or more surfaces changes with changes in viewing angle, light intensity outside or inside the assembly, or by moving one or more patterns relative to the pattern on the surface. It can be used to achieve the design effect of For example, a silhouette pattern with vertical lines on both sides of a single panel, or on each side of a two-panel assembly,
Allows for visibility from both sides of the assembly. However, 2
The six colors of the Sileramil pattern can be designed to change the visual effect depending on the viewer's vision. When two or more panels with silhouette patterns are involved with external and internal lighting, the visual effect can be varied by varying the relative intensity of the lighting.

For example, if the front panel is brightly lit and the far panel is relatively dark, only the design of the front panel will be perceived. However, if one side of the front panel is darkened and the space between the panels is brightly lit, the design of the front panel will not be clearly visible, and the design of the far panel and the objects in between the panels will not be clearly visible. or clearly visible.

Patterns with various effects, such as interference patterns, can be created by forming two silhouette patterns over and over again! By moving one pattern relative to another, for example by means of a cam, varying interference patterns can be obtained.

In addition, the changing interference pattern can be perceived by a moving inkstone with respect to a fixed pattern and a pre-print, which is effective in practical use and in decoration and other visual presentations. For example, panels of the invention may be used in shielding pattern systems currently in use in navigation to emphasize the visual or informational features of the system. In the new system according to the invention, the currently required rear lighting is eliminated by the use of ambient lighting or lighting directed by the viewer. In certain embodiments, An instep panel with a silhouette pattern is required, with the rear panel being entirely opaque, with or without a design, in part or in whole with a mirror or other reflective finish. be done.

Transparent parts of transparent objects can have two or more different colors, which provides an additional design effect. However, these effects typically involve a mirror image on the opposite surface, unlike designs formed over silhouette patterns.

It is difficult to form this J-shaped silhouette pattern over a wide area and overlap each element of the pattern in a different color so as to match it as accurately as possible. However, the method used for this is disclosed in British Patent Application Nos. 2,032,417A and 2,118,096A. Another method is to carry out the next step.

A stencil pattern with l'l 7N is applied to the substrate, for example by a suitable printing technique, transfer or similar method. Two layers of ink or other printing liquid of different colors are applied to the substrate. are continuously applied. The colored ink is repelled by the stencil material and remains on the filler between the stencil materials. The stencil material is then removed by solvent, GJL or other means.

(b) The desired pattern of color is provided by marking 1+1ilJ or other techniques, and the 1-layer photosensitive material is accurately superimposed on the original pattern with exposure from the opposite side of the transparent substrate and accompanying development. It gives a contrasting color.

(C) The required pattern is formed on the substrate by printing or other means in a single color. The photosensitive material is developed by exposure to light from the other side of the transparent panel to form a stencil in the areas between the elements of the original pattern. A contrasting colored ink or marking fluid is applied to the entire substrate and stencil. The stencil is removed by wet, heat, or other means, and the second color is removed accordingly. However, on the required pattern, two types of colors are left in a superimposed state.

(d) An electroplated shield of the required pattern is applied to the substrate by printing, stenciling or other means. The panels are then plated with two materials in contrasting colors. Stencils can be made using solvents, heat or [,1
The other steps are removed, leaving two colored materials interlaced in the pattern formed by the shield.

(e) For example, if a perforated polyester film has self-adhesive properties, a self-adhesive type 4 stencil or a self-adhesive type 4 stencil is adhered to the substrate. Two layers of ink or other marking medium with different colors are successively applied over the substrate.

The self-graining stencil is then peeled away from the substrate, leaving the desired pattern in two colors. Each color is precisely superimposed on each other. Self-attaching i5 type SJ
The stencil may form more than one layer, allowing one layer of stencil material to be removed after forming a layer of ink or other colored marking fluid.

(f) The required pattern is pudding 1~ with one color.
or formed on the obturator by other means. after that,
A second ink or other marking fluid of a different color is applied to the previously formed material of the first color and is less likely to adhere to the filler. If necessary, remove the material in the area within the range of the predetermined pattern by scraping, pasting and peeling off a self-adhesive film, or by other means to make the area transparent without MW, The required Silera pattern can be made by overlapping two colors.

(CX> Substrate (J) A stencil pattern is formed on the panel by Print 1 or other means using a stencil material that has strong adhesion to the substrate (J) or other means that has strong adhesion to the substrate and to each other. The stencil material and the ink or other marking fluid on the material are applied in succession over the entire panel by scraping, gluing and peeling off a self-adhesive film, or by other means. The areas that are removed and previously covered by the stencil are left unobstructed and transparent, while other areas on the substrate are left with two colors superimposed.

(h) The silhouette pattern is formed on a carrier paper, and the pattern's niremen 1~ is usually pu1nonl- or ``kiss diec r-cut-J (kiss diec
ut) and the pattern is transferred to J:repanel for dry transfer. The silhouette pattern is adhered to the carrier paper with a medium viscosity adhesive. Silhouette patterns can be formed by ink, two film sheets laminated, or one sheet printed to impart different colors.

If a film material is used, the desired silhouette pattern is created by "kiss-die-cutting" and unnecessary portions of the material are removed.

The adhesive on the side of the pattern opposite the carrier paper has adhesive properties with a fairly high viscosity to the transparent panel. After removing the adhesive surface protective release paper, which has a fairly low tack, the pattern is pressed against a transparent substrate. The carrier paper is then removed and
While the pattern is adhered to the substrate, the remaining 1 ft. of area between the elements in the pattern is transparent with no obscuring.

(i) self-adhesive or static clinging, such as polyhneylchloride;
printing the film by any of the aforementioned means;
It can be applied over a transparent sheet or flexible material.

Each of these means, by repeating or masking the same means applied at 1 V, as described below, will reduce the damage caused by the de-1 f-in on one side or when viewed from said one side. , a design can be formed on one side so that it looks different than the design on the other side, and is not visible when viewed from the other side. The product formed in this manner is referred to as a 1-differential arrangement or a 1-differential arrangement.

To produce "Day Farenci A Fulde 1 Ain",
The following method is used for the above two colors.

■ Forming the design by printing two or more colors over all or part of the silhouette pattern, with each layer matching as accurately as possible, by screen, lid, or other printing method. The dots, lines, and other elements of the pattern can be printed more widely in some colors than others, so that if the match is inaccurate, certain colors cannot be duplicated from the other side.

(2) By transfer or decal, the necessary design and printed patterns are formed by the above-mentioned (2) or other methods. If necessary, two or more of these can be arranged in parallel to groove the required area. A more accurate match is usually achieved in fairly small areas on the flexible material. 9. Using reramikku ink for such transfer or glass printing
71 drawing method) Nada, the -1-\7 ring membrane is burnt out in the strengthening furnace, and the P lamic ink is melted into the human face of the strengthened crow. Transfer methods include I, I, 92 type transfer, slide transfer using water, and the Ij method of transferring the pattern onto a carrying membrane or from a kifling membrane.

■ Use screen, lid or other printing methods to form one layer of the printed pattern in one or more colors, and then print the patterns and designs as needed to form the print. is born from one side
use an ink or other marking material that adheres relatively strongly to the substrate. Alternatively, the silhouette pattern can be cylindrical using clear ink or other marking materials that adhere relatively strongly to the substrate. Partially textured substrates with black, clear or other silhouette patterns can be mass-produced and the remaining steps can be carried out according to individual needs. The remaining silhouette patterns and/or designs are formed on the previously formed silhouette pattern, including a base material that strongly adheres to the previously formed first colored ink or marking material and is a substrate. Inks, powders, and other materials that do not adhere strongly are used. Areas other than those marked with the silhouette pattern are placed in a "blocked out" state. If necessary, material may be removed by scraping, pasting and peeling off a self-adhesive film, or by other means within the area of the predetermined pattern. This allows that part to be in a transparent state with no obscuring, and the necessary silhouette pattern can be designed with the necessary colors overlaid.

According to one embodiment of this method, a polycarbonate sheet is first screen printed with the required design on one side to form the required silhouette pattern with PVC ink.

After drying, the required areas of color are printed in a "blocked" manner, forming a continuous layer of ink, usually cellulose-based. It is done by doing. Once the coated print has dried, the unnecessary areas between the elements of the silhouette pattern can be removed by applying a self-adhesive film with high tack, depositing the ink in the unnecessary areas, and removing the film. removed.

The application of self-adhesive films can be carried out more economically over large areas by using laminating equipment. Further, the film can be cut into thin strips in advance to facilitate peeling off. Self-adhesive films can also be pasted and pulled against rigid or flexible substrates by being passed between nip rolls with the substrate before being pulled off the reel and re-spooled. Can be stripped. The base material may be wound on a reel or in the form of a sheet, as required.

Alternatively, the self-adhesive film can be kept adhered as a protective layer and removed immediately before use. The adhesive can be such that it remains on the ink after the protective film is removed. This facilitates adhering the product to other surfaces, such as adhering a polyester film to a glossy assembly.

IV A stencil is provided on the substrate to form the required silhouette pattern. The required design is formed with ink or other marking material in successive layers by printing, spraying or other means.

Areas other than the required silhouette pattern are "blocked out". The stencil is then removed along with the ink or other marking fluid on its surface, leaving the desired silhouette pattern and design superimposed with the desired color.

Partially processed substrates with the necessary stencils and optionally one or two layers of marking fluid formed on the stencils are mass-produced, and the remaining steps are adapted to suit the needs of the individual product. You can also do this.

A variety of stencil materials can be used, and for each material there is one or more methods for removing the stencil along with any unwanted ink or other marking material on the stencil. The stencil can be preformed by perforated film, printed film or photosensitive stencils, or other techniques that create stencil patterns. Photosensitive stencils are obtained by exposing the photosensitive layer to light through the artwork to develop the desired stencil pattern.

, / Stencils with sufficient strength, such as perforated self-adhesive PVC or polyester films, can be easily peeled off from the substrate.

Alternatively, the stencil can be comprised of an ink or other marking material that has relatively low adhesion to the substrate. The required design is formed with an ink or other marking material that has relatively strong adhesion to the substrate.

The stencil and the ink on the stencil are scraped off,
The self-adhesive film can be applied and removed by peeling or other means, leaving the exposed areas of the stencil unobstructed and transparent, and the required color for silhouette patterns and designs required. can be in a superimposed state. The adhesive may be such that it remains after removal of the stencil, allowing the product to adhere to other surfaces.

The required stencil pattern can be printed on an acrylic sheet using an organic solvent-based printing ink. After drying, the design can be formed by screen printing using PVC ink with successive layers of "block-outs" in the required areas. The required silhouette pattern can be obtained by removing the stencil and the ink on the stencil by applying and peeling off a self-adhesive film according to any of the methods described in Method (2) above.

Stencils can be formed from materials that are highly extensible in some situations, such that the ink or other marking material on the stencil splits and separates from the ink that is directly adhered to the substrate. The remaining stencil and ink thereon can be removed with a scraping solvent or other means, leaving the area where the stencil was unobstructed and clear. - By way of example, the stencil can be a water-swellable photosensitive stencil and the ink can be a water-permeable ink.

As another example, the stencil can be thermally expandable, expanding with increasing temperature.

The stencil may be made of water-repellent material, such as wax. The wax repels water-based inks and can later be removed by melting, grinding, jetting water, applying solvents, or combinations thereof after the ink or marking material has been softened.

The stencil may be compressible and/or may not properly preserve or recover the ink, or may be weakened by ultraviolet or other light rays directed through the substrate. This allows the stencil and the ink or other marking material on the stencil to be removed by scraping or jetting with high pressure, leaving the required color overlay for the required silhouette patterns and designs. .

The stencil can be constructed from a material that is dissolved by a solvent in which the ink or other marking material is insoluble. Ink or other marking material is printed with a slight overhang to cover the gaps between the stencils. However, the stencil can be removed with a solvent.
Enough of the area is left exposed so that q. Thus, the required color matching, superimposed in the required silhouette patterns and designs, is accurately obtained. The stencil can be acid resistant and removable with dilute alkaline solvents such as sodium carbonate or sodium hydroxide.

■ “Resist” where the silhouette pattern is printed as part or all of the required design.
st) Application of J technology. This is a "blockout" printed in successive layers. Areas that receive low levels of ink are required to be clear and are etched away by the solvent. This solvent is “Regis)-J”
Does not affect elements.

If a single color is required on one side of the silhouette pattern, the "resist" shall be that color and shall be applied over the colored portion forming the required design on the other side of the silhouette pattern. Ru. Instead of this,
By making the resist J transparent, there is no need for subsequent removal, and the problem of matching fine silhouette patterns applied in two or more steps can be solved. Alternatively, the "resist" may be later removed by solvent or other means, in which case it may be of any suitable color.

One example is one in which the base material is an acrylic sheet. The colors of the design can be "blocked out" with M-corrosion resistant inks. Silhouette patterns and designs can be printed with clear inks that are not soluble in alkali. Unwanted ink between silhouette patterns and design elements can be removed by etching with dilute alkali such as sodium carbonate or sodium hydroxide.

As another example, the colors of silhouette patterns and designs may be applied by virtually any ink compatible with the base material.
You can list things that are "blocked out". The silhouette pattern may be formed by hydrophilic first resist techniques. Unwanted ink is etched away with a non-aqueous solvent that does not attack the base material. The resist is scattered by its condensate (di 5persed)
.

The Vl silhouette pattern can be formed by recessing the surface of the base material. This allows the required pattern color to be applied to the "blocked out" areas. For example, it may be applied by appropriately spraying the ink onto the surface through a stencil. The areas between the elms of the silhouette pattern are required to be transparent, but the areas can be removed and cleaned during inking or after all ink has been applied;
Alternatively, these areas can be protected by a silhouette pattern stencil during inking. After applying the required color, the stencil is removed along with the unnecessary ink by any of the methods in Method IV above.

Recessed silhouette patterns and designs can be created, for example, by casting, engraving, milling, or
It may be formed by drilling, sandblasting, laser etching, chemical etching, heated foil transfer or other means.

The Vl silhouette pattern may be formed by applying the desired design and color to the "blocked out" areas and then mechanically removing the ink or other marking material. - By way of example, sharp lines of uniform or varying width are ground away by a grinding wheel, forming linear or checkered silhouette patterns and designs.

■ Silhouette patterns and designs can be formed by cut films that are usually self-adhesively transferred from the carrier layer to the sheet substrate. The required patterns and designs may be printed on the film as "blockouts" or cut layers to produce a similar effect, prior to die cutting and removal in the areas where transparency is required. It can be formed by comprising a stack of formations. The film material can be wound into reels and cut, and unwanted areas, usually formed by silhouette patterns of continuous straight or curved lines, are mechanically removed between reels. It will be destroyed. Alternatively, sheet or film material of suitable quality may be punched, burned, laser cut or otherwise cut to yield a perforated membrane with a grid, net or filigree silhouette pattern. Regardless of the shape, most form transparent areas. The holes may be formed after printing or after "blocking out" the required design.

Alternatively, the required design can be applied after the hole is formed. This can be done, for example, by spraying with a suitable stencil or by masking the areas to be formed.

Such patterned perforated sheets or membranes can be integral with, bonded to, or independent of the transparent sheet or film material.

In each of the above-mentioned methods, "blockout" is used to include any application of multiple color printing methods, e.g. four or five colors, which allows for an almost infinite number of possible color combinations in a design. Obtainable. It is possible to apply the technique to vary the color stack within the silhouette pattern and design required in the final product. Any method of design and silhouette patterning required can be applied to the sheet with the translucent or cloudy surface to obtain the effect of the translucent or cloudy surface. Alternatively, a lacquer or film can be applied to the panels according to the invention to achieve this effect. Even in these cases, the silhouette pattern and design will be different in the final product.
It is visible.

Is it desirable to protect the pattern on one or both sides of the panel? Examples of suitable methods and suitable assemblies for this purpose are as follows.

(i) Patterns and designs may be encapsulated in plastic sheets during molding or other panel manufacturing processes, such as by casting. The plastic sheet can be level with the panel surface or can be placed between the faces of the panel.

(ii) Patterns and designs may be formed on two or more transparent sheet materials that are typically held together or laminated in any suitable manner, e.g. to prevent chemical damage and/or for adhesion. The sheets can be laminated with resin or PVB film, with or without a barrier layer. Two or more sheets sealed around the perimeter can be held together by vacuum. Printed dots, etc. The elements of the silhouette pattern serve as spacers to form a continuous evacuated space between the seams.

(iii) Patterns and designs can be placed between the panel and a thin film laminated to the panel. The pattern can be separate from the film or panel, or it can be formed into the film or panel.

(1) Patterns and designs can be placed in overcoats or multiple assemblies of two or more layers. For example, it can be printed and placed inside one layer of a two-layer overcoat or multi-assembly, or it can be printed on a sheet or film on which a two-layer overcoat or multi-assembly is provided. These sheets or films can be separate or combined with one or two layers of a two-layer overcoat or multiple assembly.

Where it is difficult or uneconomical to provide opaque patterns and designs over large areas, small areas or "tiles" with edges finished to suitable precision or suitably patterned edges may be used. Combine them with each other to create the necessary and sufficient appearance as a whole! You can do as you like. Such "tiles" may be of any suitable design, but in particular the tiles may have individual letters or numbers on their sides to constitute special messages, advertisements, etc. can.

The "tile" may be bonded to a transparent base, for example by an adhesive film or adhesive, and may be provided with a protective cover layer. A "tile" may be included within a laminate or similar assembly, such as inside a two-layer overcoat or multiplex assembly.

The silhouette pattern can be a single color on a portion of each side of the panel and a different color on different sides of the remaining portion of the panel. The design of the silhouette pattern on one or both sides can be such that a single element of the silhouette pattern has more than one colored portion within that element. One or more parts of the silhouette pattern of the panel can be left in a clear state. The opaque elements of the silhouette pattern, formed with different colors on each side so that different designs appear when viewed from different sides of the panel, need not be a continuous pattern, but can be one or more of any shape. An arbitrary space can be provided between each element and other elements.

The transparent base material to which the present invention is applied may be a sheet, film or other transparent material, and may be colored by water' clear, baked on, etc., or light colored. It is also possible to do this. For example, the present invention can be applied to transparent polyester films such as Melinex J manufactured by ICI PLC.

In particular, the film can be unsupported, stretched within a frame, suspended with suitable weights, or glued to a transparent sheet material. For example, adhesive PVC film or self-adhesive PVC
A strip of film can be glued to the top of a car windscreen. Inside the car, the film has a single color pattern, which can be graded for protection from varying sun glare. However, on the side facing the outside of the car, the film can have a design, for example with the name of the car owner.

A transparent sheet or film according to the invention with a differential design on one side may be silvered or otherwise reflective on the other side, or have a static effect perceived at a distance from said other side. A mirror surface or a dynamic mirror surface can be provided.

This allows the viewer to normally not see the design on the opposite side from one side, but only when the viewer is in the appropriate position to receive reflected light from the design on the other side (and only from said one side). By alternating the illumination on both sides of the silhouette pattern, the perceived image can be changed.If you move the mirror surface, the image behind it will appear to move.

Opaque silhouette patterns can be used for other beneficial purposes. For example, the silhouette pattern may comprise or be incorporated into a heating element integrated or connected to a vehicle windscreen, building window, screen or apex wall. The heating element is
It can have a different color on each side and has a colored design on one or both sides, with the necessary visual effect. Similarly, safety grid windows, reinforcing meshes, safety warning tape, radio or television antennas, solar cell elements, and other elements in or near transparent assemblies can act as silhouette patterns according to the invention. However, one or both sides can be suitably colored.

An example of this invention when a one-way vision effect is required! According to the aspect, effects not obtained from various modifications of the prior art can be obtained.

Namely, in a variation of the prior art there are partially metalized transparent materials, called one-sided mirrors, which can be combined to achieve the effect that they can be accompanied by multi-colored designs such as advertisements. I can't. for example,
When the present invention is applied to the rear window of a promotional vehicle to give it a one-sided vision effect, it is possible to see the outside from the inside of the vehicle under normal conditions, but the inside of the vehicle cannot be seen from the outside. The design on the outside of the window can be in the form of advertising, for example the name of a company or product, and will be visible to other road users or pedestrians.

If a police officer or other safety agency wishes to see the interior of a vehicle, this window allows them to do so from a close distance, unlike a one-way mirror. This is not possible with one-way mirror windows, which makes them anathema to police officers when used in vehicle windows.

In panels according to the invention, the perceived design image and its intensity as well as the visibility through the panel depend on the illumination conditions on both sides of the panel, the light transmittance of the transparent material and the reflectivity of the surface, the silhouette pattern or the superimposed design. It depends on many factors, including the reflectivity and contrast of the colors used, the distinctiveness of the design, the ratio of opaque to transparent areas, and the shape of the silhouette pattern. If the design is located at or near the window assembly, normal daylight is sufficient to make the design clearly visible from outside the building or vehicle. In an indoor environment, artificial light can be used to emphasize the desired design image, for example by shining the light directly onto the spora 1 on a suitable surface. The perceived image is usually brighter when viewed from the direction of the angle of reflection of the light from the light source. For example, an image of a design on a window on the upper floor of a building will be perceived as brighter than an image of the same design on a window on the ground floor when viewed from the ground. This is because the former reflects light from the sky, while the latter reflects less sunlight than it does. The image of a slanted window on a vehicle is brighter than the image of a vertical window.

Depending on the conditions, the viewer can see the design or see through the patterned transparent material.

That is, it depends, among other things, on the focal point of the viewer's gaze, and also on the viewer's closeness to the panel and the factors that influence its perception of the design image mentioned above. If the design as a sign based on the present invention is provided, for example, on a transparent door, the sign can be read and the image of the person approaching the door can also be recognized on the other side of the door. . Therefore, according to the present invention, safety is ensured by making it possible to recognize dangerous areas covered by glass without impairing visibility, and there is no restriction on visibility that may cause harm to the other side of the door. The effect is that a design or a message can be added to the door.

By changing the illumination on both sides of the panel, the visual perception of the panel and the space beyond the panel can be changed. When the illumination is changed from relatively bright on one side and relatively dark on the other side to relatively bright on the other side and relatively dark on one side, appropriate patterns and designs are applied. There may be a change in visual perception when viewing from both sides of the panel. When viewed from one side, the main image recognized changes from the open design on one side to the space on the other side.

When viewed from the other side, the main image perceived changes from the space on the one side to the design on the other side. This effect can be used in other practical applications with safety, for example in making the eye perceive an alternating display in a store. For example, a panel could be marked with a warning indicating a danger, so that when the panel becomes transparent, the contents of the dangerous condition can be seen on the other side of the panel.

Adding different colors to one or more designs,
Furthermore, by illuminating with a light source that changes to different colors, it is possible to perceive a moving image between one surface or a plurality of combined surfaces. Parts of the design will only be visible when illuminated by a specific light source. For example, dyes that are photosensitive to ultraviolet light may be bonded to white ink so that they are visible under ultraviolet illumination, invisible under other illumination conditions, and indistinguishable from normal white ink in the background. You can do it like this.

Changing images can be obtained by embodiments of the invention that can involve movement, for example rotating signs in a plane or a composite plane.

By illuminating the sign relatively strongly from one direction,
Two or more different images can be recognized from the illuminated direction. The sign then appears transparent when viewed from other directions.

When the panel according to the invention is used to enclose all or part of a light source of a lampshade with an exterior design, for example, the design of the lampshade changes depending on the blinking of the light source. It looks like it's changing. If the light source is turned off, external light or shade will illuminate the outside design.

When the light source is turned on, the intensity of the light passing through the shade or the intensity of the light reflected from the outside surface of the shade is exceeded, and the design on the outside of the shade is easily obscured.

If there is a design on the inside of the shade, the design will be visible when the light source is turned on, and easily become unrecognizable when the light is turned off. This effect is of great practical value for enclosed illuminated signs and can be used no less than an array of light sources in traditional sign boxes, for example to obtain uniform back lighting. enable. In addition, the lighting from the surrounding area provides instructions (indi
cia) can be made invisible, or different signs can be made visible due to ambient lighting.

Light-harvesting materials such as Bayer L4 [LiSa J] can be used to emphasize the recognized design. For example, a suitably patterned light-concentrating window sheet or film can make the window design visible on the outside of the building and accentuate other images on the inside of the building. This results in light that is exclusively or mainly received from the outside being reflected inward and scattered by the inner design placed on the outer surface of the film sheet.
Due to radiation from the inner surface. The silhouette pattern is printed or formed as a recess by etching, milling, casting or other means, or formed in the material by punching, drilling or other notching. According to one embodiment, a silhouette pattern is printed or otherwise imprinted on a transparent material. The light-concentrating material 5 is punched or otherwise processed to form recesses, holes or torn edges, the processed areas being more visible than the remaining areas. The processed pattern can be made to match all or part of the silhouette pattern on the transparent material when placed side by side with the transparent material, so that the design of the sign etc. can be seen from one side. It will be clearly visible and will be masked from the other side by the Silera 1-pattern. Illumination may be arranged to allow viewing from one or both sides of such an assembly. Ultraviolet light may further enhance the visibility of designs applied on or within the light-harvesting material.

Illumination at the edges of the panels according to the invention is used to enhance the recognition image on one or both sides of the assembly. Light may be incident on one or more edges of the transparent material, the light being internally reflected and scattered by the interior design of the Silera 1-pattern on one side, and emitted from the other side; Make the pattern more visible. Panel products with condensing or edge lighting may be arranged sequentially to the rear.

This arrangement is usually done so that the silhouette patterns match, and if necessary, the intermediate opaque silhouette pattern is placed in the position of the other transparent material portions. This is to achieve the effect that the illuminated sign looks different on one side than on the other, and if desired,
This is so that it can be seen transparently from one side or the other with a suitable illumination intensity that is fixed or variable.

A colored light or image, such as light through a slide photograph, is projected onto the surface of the panel material according to the invention, preferably on a white or light colored area on one side of the Silera 1-pattern. At this time, visibility from the other side of the panel is maintained. This can be used, for example, in theatres, television or film studios or exhibition halls. The ink or other material forming the opaque pattern may be luminescent, fluorescent, iridescent, phosphorescent, metallic, reflective, or have other light-enhancing or eye-catching properties. It can strengthen the image that is recognized. Such enhancement may be evident under normal illumination conditions, special illumination conditions or under current excitation or other techniques. The elements of the pattern can be multifaceted or provided inside or outside the panel or assembly to enhance visibility.

The elements of the pattern can themselves be light sources.

For example, small light bulbs can be arranged and masked by a silhouette pattern. It can also be provided on one or both sides of the silhouette pattern. With appropriate circuitry and switching, the illuminated pattern can be made visible from one side and not visible from the other side, and/or visible from said other side and not visible from said one side. It can be made invisible and both patterns can be made to change. See-through from one or both sides can be provided if desired.

One embodiment of the invention by arranging fluorescent lights or other bright materials such as appropriately illuminated light collecting tubes or dots and masking the unnecessary parts of the design with paint or film material. can be configured. The paint or film material is usually black in color.

Above, the present invention has been mainly described with respect to transparent materials.

However, the invention can also be applied to translucent materials. In this case, the translucent material is one that allows some light to pass through, such as is used in regular partitions in Japan, and the translucent material is such that the image from one side is different from the other. It is required to be different from the image from the side.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

In the following examples, the same components are designated by the same numbers.

The panel shown in Figure 1 consists of a sheet of transparent colorless material (10) having a regular pattern (14) of opaque ink on one side.

The panel in Figure 2 has a regular pattern (26) of dark ink on one side of the sheet (10), overlaid with light colored (light reflective) ink (25). When viewed from the right as shown in Figure 2), the light colored pattern (25) acts to block the perspective view of the panel.

However, when viewed from the opposite side, the dark color pattern (26) with low anti-fouling properties does not obstruct the visibility of the panel. If the intensity of the illumination at the front of the panel is stronger than that at the back,
This unidirectional effect in vision is further enhanced.

Figure 3 shows the second pattern except that the light color ink pattern (25) is a different 2 (28) ink pattern.
It is required as shown in the figure. The relative placement of ink (25) and ink (28) is such that it creates a design that includes some conveyed information. Therefore, when the panel is viewed from the front, it appears opaque and the information is easily displayed. On the other hand, when viewed from behind, the design is not visible and the panel appears transparent.

The panel shown in Figure 4 (,J,, dark ink pattern (
It is the same as the panel in Figure 3 of the GEL, except that part of 26〉 has a rad color design (30). Therefore, when this panel is viewed from the front, the design (2
8) is visible, but not visible when viewed from behind, and the design (3) is visible.
0> is visible when viewed from behind, but not when viewed from the front. Furthermore, this panel has a one-way vision effect (on
When viewed from the front, it is opaque, and when viewed from the back, it is transparent except for the design (30).

The panel of FIG. 5 has the same transparent 7/opaque appearance as the panel of FIG. 4, but the structure is different. That is, the design (30) is not replaced with part of the pattern (26), but is between the dark ink pattern (26) and the colorless sheet (10), and the design (28) is replaced by the pattern (26).
It is not placed close to pattern (25), but is superimposed on pattern (25).

FIG. 6 shows various examples of configurations of elements forming patterns on the panel. Figure 6A shows elements of the same color (
25) is shown. If this element is white or another light color and is applied over the entire panel at appropriate intervals, a simple unidirectional effect can be ensured with appropriate illumination. FIG. 6B shows a two-layer niremen 1 in which one side is black or other dark color (26) and the other side is white or other light color (25). Compared to FIG. 6A, this is a panel with a higher unidirectional vision effect, and the vision from one side to the other side is improved.

Figure 6C shows another two-layer element, with one side facing 1
one color (27) and the other side is a different color (28). With this type of element it is possible to form panels with different colors on both sides. 2-layer Niremen 1 of the 6th diagram

8) and a second color portion (29) of another color. This element is bisected by a line forming a colored design on one side of the panel. The two-layer element of Figure 6F has sections (27), (30) of one color in one layer and sections (28), (30) of another color in the other layer. 6th
The element in Figure F is similar to the element in Figure 6C.

The appearance of the element in Figure F is the same as that of the element in Figure 6E.

As mentioned above, patterns and designs on panels can be protected in a variety of ways. For example, as shown in Figure 7, a transparent sheet (
12) can be glued to cover the pattern (14). In Fig. 8, the recess (1B) into which the pattern (14) is fitted is shown.
) is directly adhered to cover the pattern. In FIG. 9, the pattern (14) is fitted into a recess in the colorless sheet (12). The panel pattern (14) in Figure 10 is made up of sheets (14) with adhesive (16).
It is protected by a thin protective coating layer (22) adhered to 0). In the panel of FIG. 11, there is a pattern (14) on the inner surface of the sheet (10);

The double glazing assembly in Figure 13 consists of sheets (12)
It is similar to the first pattern except that there is also the second pattern (33) on the inner surface of the
This is the same assembly as in Figure 1.

In this example, horizontal vision is possible, as indicated by arrow (32). However, the pattern (14) does not pass the sunlight hitting the assembly, and the pattern (33) of the sheet (12) also does not let the sunlight hitting the assembly pass through, blocking the passage of sunlight as shown by ζ rays (36). The sun's rays (36) must be patterned (33) or the sheet (10
) can pass through the transparent portions (20) between the patterns (14).

FIG. 14 is a cross-sectional view of two sheets 1-(10), (12) in which horizontal line patterns (14), (33) of one color are printed on the adjacent surfaces of the two panels.

By aligning these two patterns and making them touch or almost touch, it becomes possible to see through at any angle. One sheet (1
0) in its plane, the two sheets remain in contact, but line (14) blocks the gap between line (33) and line (33) blocks the gap between line (14). (Fig. 15), and fluoroscopy is blocked. Sea 1-(10)
When you move perpendicular to that plane, lines (14), (33
) maintains horizontal alignment (see FIG. 16), and this ray further or completely blocks the sun's rays. To prevent wear of the linear patterns due to panel movement, the patterns are fitted into panel recesses or separated by vertically extending Teflon strips or similar thin slippery support materials. Alternatively, they may be spaced apart slightly.

In normal daylight conditions, the outer sheet (12) and the inner sheet (10) are in the arrangement shown in FIG. Secured. If the sheet (10) is moved away from the sheet (12) according to necessity, the sun shielding effect can be increased, and the solar ray shielding effect as shown in FIG. 16 can be ensured. At night or when the interior artificial lighting is brighter than the exterior, move the sheet (10) to reduce the transparency of the assembly to ensure privacy, and if necessary, move the sheet (10) as shown in Figure 15. It is possible to completely prevent fluoroscopy by setting the state shown in .

Position the sheet (10) inside the sheet 1-(12>,
In the cap of the double glazing assembly, the sheet (1
2) can be placed on the outside.

For example, one or both of the lines (14) and (33) can be used as a heating element to heat one or both of the sheets (10) and (12) to create two patterns of lines (14) and (33). The negative effects of different thermal expansions of the sheets on alignment can be prevented.

The automobile window shown in Fig. 17 has a first pattern (14) interposed between the sheets (10) and (12), and a second pattern (14) on the surface of the sheets 1 to (12) inside the automatic small window. 33) and 111^. Patterns (14) and (33) are
As shown by arrow (40), horizontal vision from inside the car is possible, and compared to when only pattern (14) or (33) can be seen, the incidence of sunlight into the car from above is reduced. The arrangement is as follows.

As mentioned earlier, there are several ways to create panels. Figure 181. Above, different tail by overpudding 1

Overlap a dark color such as black over another color so that the color of the design (42) is not visible from the other side, or the color of the design (48) cannot be seen from the other side. [It is normal to rub it].

Alternatively, if you don't have a background color, add an overlapping layer of black to Punk Ground (33), (46
) or between designs (42) and (48). The silhouette pattern has transparent parts (20

The applications of the product of the present invention are very wide, but the basic application is to display information, advertising, etc. designs that are visible from one side of the panel and hidden from the other side, and can be positioned or oriented as needed. Depending on your vision, you can combine the two.

Examples of applications in which the products of the present invention are useful include privacy window glazing for residential buildings, public buildings, commercial buildings, temporary buildings, automobiles, boats, yachts, and the like. Privacy window glazing with multi-color design is much more effective than window glazing with single-color design. The eye is drawn to and focused on the design and the reflected light, and vision beyond that point is blocked. Difficulties of net curtains such as cleaning, folding, seams, etc.

legree design). The product of the present invention can be used for security glass in areas requiring one-sided vision, such as transparent banks doors, decorative panels, shower stalls, film/television studios, etc. The invention also includes basketball bankboards, indoor football and ice skating enclosures,
It can also be applied to competition equipment such as cricket sight screens. The invention can also be applied for scuffle prevention, where football goal nets can be replaced with panels of the invention, or alternatively additional screens can be provided to protect the goalkeeper. Other cases that require one-way vision and are applicable to the present invention include public operating rooms in hospitals, animal observation screens, and hiding places.

The panel of the present invention can also be applied to transparent containers for pharmaceuticals and other containers where printed characters on one side cannot be confused with characters on the opposite side.

It is often desirable to have a design on one side of a transparent panel that cannot be seen from the other side. For example, in a shop window, the name of the shop should be visible from the outside of the glass window, an evenly toned-down image should be visible through the glass from inside the shop to the outside, and a "mirror image" of the design should be visible on the inside. can be prevented from being displayed on the screen. Inside the glass, dots of, for example, black or other dark colors are visible up close, but not from a distance; only the downsized image is visible. On the outside, the design can be formed by different colored parts of the same opaque pattern that exactly match the pattern on the inside. For example, on the outside of the panel the dots are generally white, but may be blue on the door 1 for designs, text, etc., and on the inside the dots are all black.

Another embodiment of the invention is to provide a design on the dark side of the panel (e.g. on the inside of an external door panel "ey;i").
Examples include those that display tJ. The panel of the present invention is
It has a one-way effect for privacy protection, making it impossible to see inside from the outside.

In this case, the pattern on the outside (sunlight side) of the door (
For example, the dots) are white or other light color, the pattern on the inside of the door (for example, the dots) is black or another dark color, and the pattern part with the words "eXitJ" is
Make the dot or part of it a conspicuous color.

There are many cases where it is desirable to have different designs on both sides of a panel. For example, on one side of a transparent glass door:
It is possible to display ``pusold'' and ``JpullJ'' in the same position or in a different position on the other side, neither display being visible from the opposite side, maintaining the transparency of the display section door.

There are many cases in which the application of the present invention enables advertising that would otherwise not be possible.

For example, an advertisement can be displayed on a transparent panel in front of the time dial at a bus stop so that the time can be seen through the advertisement. Another application is that subway windows could have advertisements facing both inside and outside. Inward-facing advertisements can be seen when passing through tunnels or at night, and can be seen through well-lit stations or during the day, and advertisements placed on the outside can be seen from outside the train, and the condition inside the train can also be seen to some extent. I can do it.

Examples of applications of the invention that do not require one-way vision include transparent partitions in buildings such as offices. However, new decorative designs are possible according to the invention. For example, one design and color pattern may be continuous throughout the hallway, while individual rooms or offices separated from the hallway may have their own different design and/or color pattern.

Other applications of the invention include eyeglasses, visors, and the like with designs that are clearly see-through, such as unusual sunglasses.
