The invention relates generally to the field of construction, and in particular to the use of a glass unit instead of the opening sashes of windows and doors, without using sash profiles into which conventional insulating glass units or insulating glass units with one protruding outer pane are usually fixed. The adaptive insulating glass unit is intended for use on windows and doors pre-installed in an opening or facade, as well as for use in the production of new facades, windows and doors, which in turn are used for glazing facades, door and window openings (fixed glazing or one with a sash opening inward, sideways, outward or upward off the frame) in residential buildings, in public and industrial buildings, display structures.
An insulating glass unit is known in the prior art, the prototype, which is the closest analogue disclosed in DE 19733154 A1, publ. 2/4/1999. An insulating glass unit consists of a pane located outside the building, a pane located inside the building with a peripheral edge projection opposite the outer pane, with a spacer element that is installed at the edge between the outer and inner panes with a gas seal, as well as an outwardly open U-shaped profile between the panes for fittings, which is also located at the edge of the spacer element and separated from it. Moreover, the outer frame is at least partly formed by additional insulating glazing, consisting of the pane located inside the building, the outer pane with the edge projection located opposite the pane in the area related to the sash structure, and the spacer element that is installed gas-tight at the edge between the inner and outer panes. Moreover, the zone that belongs to the sash structure further provides for a profile between the panes separated from the spacer element, which is closer to the sash structure than the spacer element, that is in the zone related to the sash structure, between the panes there is a profile separated from the spacer element, which is closer to the sash structure than the spacer element, which serves to accept fittings that can interact with the fittings of the sash structure, and the seals that can interact with the sash structure.
The disadvantage of the above-disclosed technical solution is the complexity of manufacture of a glass unit with a glued-in profile due to the non-parallelism of planes between the outer panes caused by the glass units press assembly technology, which becomes even more pronounced when the glass unit undergoes the stage of gluing in the profile, which subsequently leads to:
complexity of positioning the profile relative to the edges of the outer panes;
impossibility to create uniform pressure to the outer panes when gluing in the profile;
uneven gluing of the edge zones;
increased risk of unit depressurization;
high reject rate when assembling the finished product.
At the stage where the glued-in profile is inserted during the assembly of the glass unit, problems arise associated with the positioning of the profile both before pressurization of the glass unit with the glued-in profile in the assembly line, and after pressurization, since the glued-in profile gets uncontrollably displaced under pressure, resulting in a defective product. In addition, existing technologies enable relatively easy assembly of a glass unit with one chamber between two panes and a glued-in profile. However, in cases where there are two or more chambers and more than two panes, significant problems arise associated with the assembly of two- and three-chambered glass units with a glued-in profile due to the unfitness of the existing assembly lines for performing said operation in automatic mode. All latter-day two- and three-chambered glass units with a large glazed area, and especially those featuring glass sheets with thin nominal parameters, are assembled on automatic lines in a position close to vertical. Thus, it is possible to insert and glue in the profile into them only after the insulating glass unit has been assembled with two extreme protruding panes by subjecting the ready-assembled glass unit from the assembly line to gluing in of the profile into it in order to adapt the multi-chambered insulating glass unit to specific window and door systems.
The objective of the invention claimed is the development of an adaptive insulating glass unit with high consumer properties, which can be used for the installation of windows with a sash opening outward, sideways, upward and inward off the frame, fixed windows, as well as doors.
The technical result of the invention is fast and accurate positioning of the glued-in profile, which should ensure firmly secured fittings and seals and their normal function by means of creating of uniform pressure on the outer panes when gluing in the profile and ensuring the stable position of the panes of the adaptive insulating glass unit relative to each other and its tightness irrespective of the error in the parallelism of the outer panes arising during the production of a glass unit on the assembly line and its natural deformation during the installation and gluing in of the profile. The technical result is attained through the aid of an additional spacer element that presses the profile to the panes until the polymerization of the glue that fixes the profile to the pane and through the aid of an elastic adhesive sealant that fills the gap between the profile parts as per claimed embodiments 1 and 3, and between the profile and the pane as per claimed embodiment 2, and additionally secures the spacers, with the combined action of the profile, elastic adhesive sealant and spacers further protecting the panes from shifting during operation.
Additional technical results are also attained:
increased light transmission, thermal insulation and soundproofing properties of existing window and door systems, when using an adaptive insulating glass unit, without the need to reconfigure production processes and without the need to readjust and replace equipment in order to produce windows with improved specifications on existing production sites;

The invention may best be understood by reference to the following non-limiting description taken in connection with the accompanying drawings in which:
1—first part of the profile; 2—second part of the profile; 3—first outer pane; 4—second outer pane; 5—spacer frame; 6—spacer element; 7—inner pane; 8—absorbent element; 9—layer of sealant; 10—profile; 11—drip strip; 12—sill; 13—frame; 14—building wall; 15—layer of hardened foam.
The claimed adaptive insulating glass unit is assembled as follows. Two outer panes (3, 4) and the inner pane (7) located between them are interconnected in sequence through the aid of spacer frames (5) using a conventional press designed for the assembly of glass units. However, the outer panes (3, 4) have both greater length and greater width than the inner pane, with their edges protruding beyond the outer part of the spacer frames. Alternatively, the outer part of the spacer frames is sealed around the perimeter with adhesive sealant. As a result, there are sealed chambers formed between the panes (3, 4, 7), which can be filled with an inert gas. Then the profile (10) is installed, which can be made of wood or polymer material with similar or better thermal insulation properties, selected in such a way that the temperature of the inner pane corresponds to the specified operating parameters and the density of the profile material enables to fix the fittings in it; for this purpose, one of the profile surfaces (10) is treated with glue, and then the other surface of the profile, located at an angle of 90 degrees to the surface treated with glue, is pressed against the ends of the inner panes (7), and then the part of the profile treated with glue is pressed against the inner surface of the outer pane (4) (the inner surface of the pane protrudes beyond the outer part of the spacer frames). Since the width of the profile (10) is less than the distance between the outer panes (3, 4), there is a space formed between the profile (10) and the outer pane (3), into which the adsorbent element (8) and the spacer element (6) are inserted. Then, the spacer element (6) is used to create pressure that is high enough for effective bonding of the glue-treated surface of the profile (10) to the inner surface of the outer pane (4), but not enough to cause the destruction of the panes and depressurization of the glass unit. Spacer elements are installed as often as necessary in order to create even pressure over the entire bonded area. The installation frequency of the spacer elements is selected experimentally or by calculation and depends on the profile material, geometric shape of the profile, weight of the panes and operating conditions of the adaptive insulating glass unit. The spacer elements are executed in any of the known ways, for example, in the form of spacer paired wedges, in the form of an eccentric, in the form of a helical spacer element. The pressure generated by them, depending on the type of spacer element, can be adjusted manually, by hand through the aid of a torque wrench, electronically, mechanically, or by a combination of said control methods. The profile (10) is installed along the entire circumference of the glass unit and connected in the corners of the glass unit with a miter cut or counter-profile or a pin/eyelet, or by other known methods. After attaching the spacer (6) to the profile (10) and creating the required pressure, the formed space is filled with a layer of adhesive sealant (9). The profile (10) is typically obtained by milling, and it is a mating part to the window or door frame, into which an adaptive glass unit will be inserted, just as a sash with a glass unit would be inserted. Where the claimed glass unit is used for the opening sashes, fittings and seals are fixed on the outer surface of the profile (10), holes and cutouts are made in the outer panes for fixing the fittings in order to adapt the adaptive insulating glass unit to specific window systems, and the adaptive insulating glass unit is installed in the window frame, including in the existing frame (without dismantling it from the facade or wall opening) when replacing the sash. Where the claimed glass unit is used for the fixed glazing, for example, of a building, it is installed in the window opening of the building (without the use of a frame) or in the window frame when replacing the glass unit in the existing frame (without dismantling it). The claimed glass unit is installed in the opening of the building with a certain gap (which is taken into account in the manufacture of a glass unit of the required dimensions) around the perimeter between the wall of the building, and said gap is foamed with the formation of a layer of hardened foam (15), followed by installation of a window sill (12) inside the premises and of a drip strip (11) outside.
The claimed design of the adaptive insulating glass unit (
The use in the claimed adaptive insulating glass unit of a profile, whose one surface rests on the inner surface on the plane of the protruding edge of the outer pane, and whose other surface rests on the ends of the inner panes, provides a sufficient number of profile support points in the glass unit, which yields accurate and fast positioning of the profile around the circumference of the glass unit, reduced reject rate in the manufacture of glass units, and, ultimately, normal operation of fittings and seals accurately positioned in the adaptive glass unit.
Spacer elements used in the claimed adaptive insulating glass unit allow dosing pressure when bonding the profile to the pane through the distribution of pressure from the spacer element over a large plane, which reduces the risks of depressurization and destruction of the glass unit.
The claimed adaptive insulating glass unit allows increasing consumer properties-light transmission, energy efficiency, noise insulation—since the absence of a frame profile allows increasing the area of the translucent part, increasing the number of chambers with the same frame width in comparison with conventional glass units, which are mounted in a frame profile, increasing the thickness of the glass unit, designing the glass unit using thicker and heavier panes without the risk of loss of geometry, as is the case with the use of conventional sashes with heavy glass units.
The manufacturing productivity of the claimed glass unit is increased by simplifying the profile positioning relative to the edge of the outer panes and reducing the material consumption.
