Description

The group of inventions relates to technologies and equipment for obtaining 3D / Vario images on transparent glass in retail, office and residential premises.

Currently, devices for displaying various images are very actively used. The range of application of these devices is quite wide. They are used for advertising events, including in exhibition and trading rooms, for interior decoration of residential and office premises, in educational institutions, etc. Structurally, devices for displaying images are usually presented in the form of stands, paintings, stained-glass windows, etc.

For example, the VITRAPLEX multilayer art stained glass window is known, containing a substrate - a base glass sheet and an art image placed on the substrate, made in the form of a contour of a polymeric material filled with colored polymer acrylic varnishes, the image being covered by a sheet of transparent material attached to the substrate with an EVA or PVB adhesive film followed by a rigid connection of the substrate and the sheet to each other by thermal vacuum preloading (see published application P №2014131207, Cl. B05D 5/00, 2016).

As a result of the analysis of the performance of this stained-glass window, it should be noted that this is a very typical design of products of this type.

The proposed solution does not allow to obtain stained-glass windows with 3D / Vario images; the technology for producing stained-glass windows is very expensive and unsuitable for replication.

One of the clearly traced development trends of such products, regardless of their purpose, is to increase the realism of the images made on them, including obtaining three-dimensional images.

It should be noted that the formation of three-dimensional images for their demonstration has been used for a long time.

So, a picture with a multi-dimensional three-dimensional image consisting of a frame is known, on the front side of the frame a canvas with an artistic image is fixed, in front of which a light-scattering grid is installed to change the contrast and increase the depth of the image, closed outside with glass.

Plates are installed in the depth of the frame, on which fragments of the artistic image are added to supplement the main image, which are a three-dimensional part of the main image.

In places of the artistic image requiring light spots (candle flame, bonfire, moon, sun, traffic light, light path on the water, etc.), light sources are located behind the canvas or behind the inner plates. The light sources are installed on the electronic board, which is the back wall of the picture and to which the mains supply is connected.

In the cavity of the frame between the canvas and the inner plates to create a light image with clear boundaries (candle flame, sun, moon, etc.), opaque aluminum foil partitions are installed.

To view the picture set in the exhibition position (on the wall, on the podium in the hall, etc.) and include an electronic board in the mains. Due to the given sequence of switching on the light sources when viewing an artistic image, the effect of volume and the real flame of the candle is created, which makes oscillations. In the same way, the oscillating light reflection of the moon from the water surface of the lake, the flickering of the water surface of the lake, the flickering of stars in the night sky, the movement of the moon in the sky or the sun setting behind the clouds are created. This design of a picture with a multifaceted image allows you to create volumetric lighting of a face or a bouquet of flowers with the illusion of their volumetric image (see RF patent No. 2514226, class B44F 1/00, 2014).

As a result of the analysis of the known solution, it should be noted that the design of the picture is very complicated, the execution is cumbersome, it requires a power source or network connection, and, in addition, the quality of the generated volumetric image is very low, since the location of the fragments of the art image on sheets located at different distances from the main image, leads to the fact that when viewing each fragment of the image is perceived separately, and this leads to a violation of the integrity of the perception of poor the same image. In addition, the proposed solution is a complete stand-alone product and does not allow converting a standard glass display case into a 3D / Vario stained glass window.

Currently, to solve the problem of obtaining high-quality images (both stereo and Vario), optical imaging systems based on the use of lenticular rasters or, as they are also called, lens structures are quite actively used. When using lenticular rasters, a transparent flat base is used to form the optical system, parallel lenticular lenses are extruded on one side of the lens and encoded stereo or Vario images are printed on the other. To obtain high-quality images, the focus of lenticular lenses must be on the encoded images. The production of lenticular rasters has been mastered by industry, the technology for applying encoded stereo or Vario images to the base has been developed. As examples of the use of lenticular rasters for the formation of high-quality images, one can cite the solutions according to the patents of the Russian Federation No. 2439714, 145714, 88340.

The use of such rasters to form high-quality images of paintings, banners is also known.

Known decorative insert-stained-glass window, made in the form of a substrate placed in a frame or having a border around the contour. A stereo or Vario image is placed on the substrate, which is applied to a sheet attached to the substrate. A lens raster is attached to the image sheet, attached to the substrate by means of glue or double-sided tape and representing a thin polymer transparent plate, one side of which is smooth and microscopic lenticular lenses are made on the other side. When viewing a stained glass image, raster lenses transform the encoded image (perform decoding), creating a stereo or Vario effect (depending on the vertical or horizontal orientation of the lenses) of the image. (see RF patent for utility model No. 94427, class А47В 96/00, 2010 - the closest analogue for the device).

As a result of the analysis of the known device, it should be noted that the formation of a stereo or Vario image in a stained glass window based on the use of a lenticular raster allows to obtain a stereo or Vario image. It is also very important that the lenticular raster does not beat, crack or crack, that is, it is safe to use. However, to obtain large-sized 3D / Vario images with viewing them from a distance of 5-10 meters, expensive lenticular plastic with a thickness of 3-6 mm is required. The precise application of coded images to large lenticular plastic is a complex technical task. Moreover, the application of images is irreversible, i.e. each new product requires a new lenticular material. All this does not allow to realize the task of turning a standard glass display case into a 3D / Vario stained glass window.

There is a method of producing a stained glass window on glass by applying a heated aqueous solution of celluar glue to which surface is applied, and then drying the glue and drawing, and after drying, a single or multi-layer coating is applied to the drawing (see RF patent No. 2052402, cl C03C 17/34, 1996).

As a result of the analysis of the known method, it should be noted that this method does not provide 3D / Vario images.

A method for obtaining a three-dimensional image of objects, comprising a coded image of an object and an optical lens raster, the image being placed in a plane defined by the focal lengths of the lenses having the maximum value of the focal length in the meridional section, the plane defined by the focal lengths of the lenses having the meridional cross section the minimum value of the focal length, located between the raster and the image (see RF patent No. 2224273, CL G02B 27/22, 2004 - naib Lee close analogue to the process).

As a result of the analysis of the known method, it should be noted that it involves the use of lenticular lenses with different values of the curvature of the optical surfaces, given by the formula, which is a very expensive and technically difficult solution, therefore, it is practically not used.

The technical result of this group of inventions is the development of a method for obtaining 3D / Vario images on glass (hereinafter referred to as images) and a device for its implementation, providing large-sized and high-quality images by providing the ability to perfectly fine-tune the encoded image relative to the optical system of the device, as well as expansion of functionality due to the unlimited in number of rotation of plots by the operational replacement of encoded images, which solves The task of reusable use of the device.

The specified technical result is ensured by the fact that in the method of obtaining images on transparent glass 3D / Vario using a lenticular raster and a substrate with an encoded image placed on it, the new is that a self-adhesive film with a lens profile that is placed on the glass is used as a lenticular raster, the substrate with the encoded image is placed in supports opposite the lenticular raster and with an air gap relative to it, after installing the substrate in the supports to obtain high-quality the images adjust the position of the encoded image relative to the lenses of the lenticular raster, moreover, to adjust the image sharpness by axial movement of the substrate in the supports, the air gap is adjusted, the image position relative to the raster is adjusted by angular movement of the substrate using an eccentric mounting element of one of the supports, and the phase is adjusted by moving the substrate perpendicular to the lens of the lens raster.

In a device for receiving 3D / Vario transparent glass images containing a lenticular raster and a substrate with an encoded image placed on it, the new thing is that the lenticular raster is a self-adhesive film with a lens profile glued to the glass, the substrate with the encoded image is located opposite the lenticular raster and with an air gap relative to it, moreover, the device is equipped with upper and lower supports, each of the supports is made in the form of a supporting element, on which the installation and an element for mounting the substrate, the mounting elements of the supports having the ability to independently adjust the movement relative to the support element to control the axial and angular position of the substrate relative to the lenticular raster, while the substrate can be installed in two upper and two lower supports, and the supporting the element of the two upper and one lower supports is made in the form of a threaded rod with a fifth having an installation surface, and the installation element of these supports is made in the form of a ki with an internal threaded hole screwed onto the thread of the rod, while on the forming surface of the sleeve there is an annular groove designed for placement in it with the possibility of movement and installation in a predetermined position of the substrate, and the element of the other lower support is made in the form of a rod with a fifth having an installation the surface, and the mounting element of this support is made in the form of a sleeve mounted by a hole on the rod with the possibility of axial movement, rotation and fixing on the rod in a predetermined axial and angular position and, moreover, on the forming surface of this sleeve there is an annular eccentric groove designed to accommodate the substrate in it with the possibility of movement and installation in a predetermined position, while all bearing bushings can be equipped with handles for their rotation. The encoded image is made on a separate sheet attached to the substrate by means of glue, and a U-shaped clamp can be installed along the contour of the substrate with the sheet encoded with the image to hold the image sheet against the substrate. On the reverse side of the substrate, a two-dimensional image can be made or light sources placed.

In the claimed group of inventions, one of the inventions (device) is intended to implement another (method), therefore, they form a single inventive concept, and the requirement of the unity of the invention in the application materials is met.

The essence of the claimed group of inventions is illustrated by graphic materials on which:

- in fig. 1 is a side view of a device for acquiring images;

- in fig. 2 - view A according to fig. one;

- in fig. 3 - support upper and lower, a cut by a vertical plane;

- in fig. 4 - lower eccentric support, cut with a vertical plane.

The claimed device for acquiring images can be structurally implemented in the form of a wide range of products containing transparent glass - in particular, in the form of an advertising stained-glass window, information stand, light box, etc. Below, when describing the device, its structural implementation on a glass showcase of a trading floor will be considered. The term “glass” in this application should be understood to mean almost any optically transparent material (quartz glass, plastic, etc.) used in the manufacture of shop windows, podiums, interior decoration, etc.

The device is a lens raster 1 made in the form of a thin self-adhesive film with lenticular lenses. As such, a self-adhesive optical material, a lens raster, disclosed in the description of a utility model of the Russian Federation No. 103629, can be used. Such a lens raster, by means of an adhesive layer deposited on its flat surface, is glued onto a glass display case from the inside of the glass 2 so that the lenses have a vertical orientation necessary for forming 3D images and a horizontal orientation for obtaining Vario images.

The device also contains a substrate 3 made in the form of a flat sheet, mainly rectangular or square, made of glass, foamed PVC, foam board or other material. The main requirement for the substrate is the deviation from the flatness of its surface should be no more than 100 microns over the entire area, this allows you to create high-quality images.

An encoded image 4 is placed on the substrate 3. The encoded image 4 is preliminarily applied to a sheet of paper or film by known printing methods (offset printing, inkjet printing, digital printing, etc.). Then the sheet is applied to the substrate and attached to it with a temporary glue applied with a brush or spray. This embodiment of the substrate 3 allows you to replace the demonstrated art plot an unlimited number of times. This is advisable, for example, when installing the device in the sales area for advertising products located in it.

On the reverse side of the substrate with the encoded image 3 can be placed the usual two-dimensional image (the position is not indicated). It is applied when the back of the substrate is in the public viewing field and requires decoration, including the placement of advertising information.

Light sources can be placed on the reverse side of the substrate (not indicated by the position), for example, LEDs, if you want to use the device in the dark.

As noted above, for high-quality image reproduction, the lenticular raster 1 and the substrate 3 with the encoded image 4 placed on it must be located relative to each other in a strictly defined way, in which the focus of each lenticular raster lens in the working position of the device should be on image 4. Feature The claimed solution is that the lenticular raster placed on the glass is positioned by the lenses to the encoded image placed on the substrate, and not vice versa, as is customary in the classic version, with an adjustable air gap between the lenses and the image. By adjusting the air gap, it is possible to precisely adjust the sharpness of the image, and by adjusting the inclination of the substrate relative to the lens raster, it is possible to obtain the perfect combination of the encoded image with the lenses over their entire area. This allows you to achieve ideal image quality that is not achievable with other methods of applying the image to lenticular rasters.

Based on the foregoing, in the development of this device, they abandoned the traditional design of such devices in the form of a monolithic package and structurally implemented it in the form of two non-mechanically contacting, but linked optical parts.

The first such part is the lenticular raster 1, which is attached, as already described above, to the glass 2 of the display case from the inside.

The second part of the device is a substrate 3 with encrypted image 4 placed on it, made similarly to the one presented above.

It is such a constructive solution of the device that made it possible to obtain a high-quality large-format image due to the fact that these two parts are mechanically “decoupled” from each other, but have the ability to adjust the position (axial and angular) of one part relative to the other, that is, adjust the optical system of the device.

Attached to the interior object, the lenticular raster 1 is one such part installed stationary and not having the ability to adjust movements.

The second part of the device, the substrate 3, is mounted, for example, on the same glass with the possibility of adjusting movements to ensure that the optical system of the device is adjusted so that the foci of the lenses of the lens raster are on the image 4 of the substrate 3 over its entire area (due to the optimal size of the air gap) . Such adjustment is carried out using the installation and adjustment mechanism of the substrate, which is made in the form of upper and lower supports, for example, two lower supports 6 and 7 and two upper supports 8 and 9.

The two upper supports (8 and 9) and one lower (support 6) are made identical to each other, and each of them contains a support element made in the form of a rod 10 with a fifth having a flat mounting surface A for fixing on glass 2. There is a rod on the rod thread. Each of these three supports also contains a mounting element 11, made in the form of a sleeve having an axial threaded hole, as well as an annular groove 12 made on the outer forming sleeve.

In the assembled position of the support, the sleeve 11 is screwed onto the thread of the rod 10.

The second lower support 7 contains a support element 14 in the form of a rod with a fifth having a flat mounting surface A for fixing on the glass 2 similarly to the supports 6, 8, 9, for example, by means of glue (or vacuum). On the rod 14 with the possibility of axial movement along it and turning, a mounting element-sleeve 15 is placed. An annular groove 16 is made on the outer forming sleeve 15, the bottom "B" of which has an eccentricity "e" relative to the axis of rotation of the sleeve 15. In the sleeve 15, a radial threaded the hole in which the locking screw 17 is screwed in, designed to fix the sleeve on the shaft 14 in a given angular and axial position.

To ensure rotation relative to the rod, each sleeve can be equipped with a handle 13. If the dimensions of the sleeve do not allow the handle to be mounted on it, then the outer surface of the sleeve between the groove and its outer end is made with a turnkey facet, in particular, end or cap.

The size along the width of the grooves 12 and 16 should be such that they can be moved under a small force substrate 3.

The claimed method, by means of the above device, is as follows.

Installation of the device (for example, on glass 2 showcases of the trading floor) is as follows.

Initially, the substrate 3 used to implement the method is prepared for installation. To do this, take a substrate with a temporary adhesive applied to it and lay a sheet with a printed coded image on it, fixing the sheet on the substrate with glue. It is highly advisable to press a sheet with an image fixed on a substrate and additionally press it along the perimeter with a retainer 17, made in the form of a U-shaped profile, one of the sides of which should be made elastically curved. This will prevent twisting of the sheet on the substrate during long-term use due to temperature differences, drafts and surface tension. The substrate preparation process is complete.

Let the size of the image placed on the substrate be 50 × 100 cm (width × height).

On the glass 2 showcases from its inner side are glued in the same way as described above, a self-adhesive film with a lenticular raster.

Further, on the glass from the inside, in the region of the corners of the lenticular raster, the supports 6, 7, 8, 9 are fastened with glue-sealant. The bushings 11 are screwed onto the threaded rods 10 of the supports 6, 8, 9. The sleeve 15 is put on the rod 14 of the support 7. Installation the bushings are carried out so that their annular grooves are located in the same vertical plane at a distance close to the raster focal for lenses. Such an installation can be controlled in a known manner, for example, by a template.

The prepared substrate 3 is inserted (pushed) into the grooves of the sleeves, positioning it so that the image 4 faces the lens of the lenticular raster. Due to the correctly selected size of the grooves 12 and 16, the substrate has the ability to move with little effort and at the same time is guaranteed to maintain its position after adjusting the sharpness and position of the encoded image relative to the raster lenses.

Next, adjust the sharpness of the image by adjusting the size of the air gap, i.e. combining the encoded image with the focus of the lens of the lenticular raster. To do this, by turning the sleeves 11, each of which during rotation makes axial movement along the threaded rod, move the substrate 3 in the axial direction until the image in the corners of the base is in the focus of the lenses of the lenticular raster. Separate adjustment of each support provides the most accurate installation of the substrate with the encoded image in the axial position over the entire image area. The result is controlled by the sharpness of the image in each corner of the substrate.

Next, by turning the sleeve 15 set the image relative to the lenses in an angular position. Considering that the bottom B of the groove of the sleeve 15 is made with an eccentricity relative to its axis of rotation, when this sleeve is rotated, the substrate with the encoded image performs an angular movement (rotation), adjusting the image relative to the raster lenses in angle. After adjusting the angle, the sleeve 15 is fixed in a predetermined angular position by the locking screw 17.

After the focus and parallelism of the lenses and the encoded image are precisely set, the phase is adjusted by lightly moving the substrate horizontally in the grooves 12 and 16 relative to the lenticular raster perpendicular to its lenses. This is necessary in order to provide ideal viewing conditions for the viewer who is in the center of the image.

If it is necessary to replace the image, the substrate is easily manually removed from the sleeve grooves, the sheet with the encoded image 4 is removed from the substrate and a new one is installed in its place, then the setup procedure is repeated. With some experience, replacing the plot takes no more than 5 minutes.

Additional advertising and other information printed in the form of a two-dimensional image on the back of the substrate 3, allows you to most efficiently operate the device when the back of the substrate is available for public viewing. For applying advertising information, the same method is used as for applying encoded images from the front side of the substrate 3.

Backlighting on the back of the substrate in the evening, compared with frontal lighting, improves the volume of 3D images, since in this case there are no reflections and side light scattering. As light sources, for example, LEDs can be used - similar to those used in standard lightboxes.

The proposed solution allows you to receive images on any transparent 3D / Vario glass with the ability to quickly replace scenes with ideal image quality at minimal cost and in terms of the combination of features and the achieved effect has no analogues in the market.
