Description

[0001] Insulating glass element for doors or windows or other glazing with transparent edge seal for use in conservatories, shopfitting, refrigerated display cases and special display case construction as well as window and door construction.

[0002] In the areas of refrigerated display cases, shopfitting, and special display case construction, insulated glass is used to store food at temperatures of 5 degrees Celsius or below, in the so-called deep-freeze area, while simultaneously presenting it to customers. Refrigerated shelves with glass doors are also used for this purpose.

[0003] Until now, aluminum spacers, based on the same principle as those used in insulating glass units in buildings, were primarily used as spacers between the two parallel panes of glass in glass doors. To achieve a tight seal between the glass pane and the spacer, a butyl cord was applied using an extruder. This black material hardens to a permanently elastic state.

[0004] Furthermore, glass spacers are known which, like aluminum or plastic spacers, are laminated onto the respective glass pane using EVA film or glued on using UV light curing adhesive, or UV adhesive for short.

[0005] The aluminum or plastic spacer, in the form of a profile, is perforated to the space between the panes. The cavity of the aluminum or plastic spacer contains a water-absorbing material, such as silica gel or a molecular sieve. The air trapped between the two panes contains moisture, which would condense as precipitation on the glass panes within the glazing unit if the dew point were reached. The water-absorbing material binds this moisture up to its saturation point. If no new air enters the space between the two panes due to leaks in the butyl cord and the outer sealant, such as polysulfide, the risk of condensation forming in the space between the panes is permanently eliminated.

[0006] Pressure equalization during manufacturing is currently achieved through openings in the aluminum or plastic spacer, or dried gas or noble gas is introduced into the space between the panes, and the openings are then sealed. Finally, the inserted aluminum profile is bonded to the glass on the outside by a sealing compound. The sealing compound and butyl cord thus form a double sealing system.

[0007] Since neither aluminum or plastic spacers nor the sealing compound have any transparency, they interfere with the visibility or transparency through the insulating glass element or cause a disturbing shading.

[0008] EP 2 456 942 A1, for example, discloses glass spacers which are glued between two glass plates.

[0009] It is known from EP 3 515 258 A1 that glass spacers are present on three outer edges of an insulating glass unit. To prevent condensation, aluminum or plastic spacers with a water-absorbing material are used on one outer edge of the insulating glass unit. However, even at this outer edge of the insulating glass unit, the visibility or transparency is impaired, and shading occurs. Furthermore, water-absorbing material is required, and a spacer different from the glass material is used only for this water-absorbing material.

[0010] The glass spacers, as well as the aluminum or plastic spacers, are predominantly oriented to form a quadrilateral, for example a rectangle, square, or other rectangular, or even polygonal and / or circular shape. Insulating glass units can also be curved.

[0011] Depending on the design of the glass spacers as well as the aluminium or plastic spacers, the end face of one end of the spacers lies partially or completely against a longitudinal surface or an end face of the end of another, adjacent spacer, which places high demands on the arrangement of the sealants, the tightness and the alignment to each other.

[0012] Insulating glazing units are known from the prior art which include spacer profiles, wherein corner elements are present in the corner area of ​​the respective insulating glazing unit, which can each be inserted into the adjacent ends of the profiles.

[0013] The DD 217 502 A1 spacers are designed as profiles into which corner elements in the form of insertable angle brackets can be inserted. The profiles, which are tubular, can be made of glass, with water-retaining material arranged within them.

[0014] Similarly, for example, DE 72 27 927 U1, DE 75 30 130 U1, DE 40 02 339 A1, DE 25 32 896 C3, EP 0 925 42 B1, DE 20 2008 017 882 U1 disclose insert angles which can be inserted into the spacers as profiles for forming corners with variable angles or as a corner.

[0015] Furthermore, WO 2017 / 064160 A1 and EP 3 362 628 B1 disclose insertion angles which can be inserted into the respective end face of the respective spacer and also include openings or passages into the space between the panes or the profile of the spacer.

[0016] The solutions mentioned have in common that they are inserted into the spacers and primarily serve to stabilize the spacers as a frame. Due to the large contact surfaces between the end face of the respective spacer and the insertion angle, they offer little or no sealing, necessitating additional sealing measures. Similarly, mounting the spacer on the end face of a glass spacer, which has a closed end face at both ends, is not possible.

[0017] The object of the invention is therefore to produce a reliably manufacturable and universally applicable multi-pane insulating glass unit using plane-parallel or curved glass panes, in which only glass spacers are used and connecting elements are present in the area of ​​each pair of adjacent glass spacers, wherein the design is simplified and additional functions are foreseeable or can be integrated subsequently without additional effort. In addition, the manufacturing process is to be simplified.

[0018] The invention provides, in the specified application, an insulating glass unit for multi-pane doors, windows, or other glazing with a transparent edge seal and an air gap between the panes. The insulating glass unit comprises a base pane and a cover pane and has a circumferential edge region. At least two glass spacers are arranged circumferentially at or along the edge region between the base pane and the cover pane. A connecting element is arranged in at least one space between the at least two adjacent glass spacers, such as at the end faces or between an end face and a longitudinal edge. The connecting element bears directly or indirectly against the two glass spacers.A laminating layer in the form of an ethylene-vinyl acetate copolymer is present between the base pane and the at least two glass spacers and the at least one connecting element, and between the at least two glass spacers and the at least one connecting element and the cover pane. Alternatively, the at least two glass spacers and the at least one connecting element are bonded or joined to the base pane and the cover pane using a UV-curing adhesive. At least one connecting element or at least one of the glass spacers has at least one opening to the space between the panes.

[0019] By having at least one opening in the glass spacer to the cavity between the panes, filling the cavity with an inert gas is simplified. Additional components at the edges or as spacers can be omitted if the glass spacer already has the opening to the cavity, thus significantly simplifying the filling process.

[0020] This creates a transparent insulating glass unit with a surrounding transparent edge, ensuring maximum visibility and transparency while also providing the necessary gas tightness and stability. A desiccant is no longer required, eliminating the need for metal or plastic spacers. Furthermore, this design results in a more streamlined production process and eliminates additional energy-intensive production steps.

[0021] A summary of glass panes includes the base pane and the cover pane, provided that a separation of the terms does not appear necessary.

[0022] The base and cover panes can differ in their dimensions. For example, the base pane can be larger than the cover pane, or vice versa, or the base and cover panes can be the same size. For instance, at one edge or opposite edges, and thus at the respective glass spacer, one of the glass panes can be larger or longer than the other, with the respective glass spacer being flush with or recessed from the edge of the smaller glass pane.

[0023] Insulating glass panes and insulating glass units are synonymous in this context. For simplicity, the term insulating glass unit is predominantly used in the text. Similarly, glass spacers and spacers are to be understood as synonymous, as no distinction is made regarding different materials.

[0024] EVA is also used as an abbreviation for ethylene-vinyl acetate copolymer and is synonymous. Ethylene-vinyl acetate copolymer, or EVA, can be in film or granular form and forms a laminating layer.

[0025] UV-curing adhesives, UV-curing adhesive layers, or UV-curing bonding can also be referred to simply as UV adhesives, UV adhesive layers, or UV bonding, which are known in themselves or for bonding with glass and are processed or can be processed in a manner known in themselves.

[0026] The term "round" refers to a flat shape or surface that essentially has no corners; thus, circular, oval, and any other cornerless shape are included. However, straight edges may be present that transition into a curve without any corners.

[0027] A simple form of an insulating glass unit with at least two glass spacers has, for example, a round or rounded shape, i.e., a shape without corners, in which, for example, only two curved glass spacers can be used. According to the invention, a connecting element is provided in at least one of the spaces between the two adjacent glass spacers. Likewise, a connecting element can also be provided in each of the spaces between the two adjacent glass spacers.

[0028] However, it is also conceivable that three, four, or more glass spacers are present or arranged in such an insulating glass unit, for example, with a round or rounded shape, i.e., a shape without corners. Accordingly, a connecting element is present in at least one of the spaces between the two adjacent glass spacers.

[0029] It has proven advantageous to have a connecting element in each of the two spaces between two adjacent glass spacers, as this simplifies filling with noble gas, for example argon.

[0030] Besides round or rounded shapes, i.e., shapes without corners, polygonal shapes or hybrid shapes combining round and polygonal forms are also possible. An example of a polygonal shape is a triangle or quadrilateral, although other polygonal shapes are also conceivable. An example of a hybrid shape combining round and polygonal forms would be a semicircular shape, although other hybrid shapes are also conceivable.

[0031] Examples of suitable quadrilaterals include rectangular, square, or other regular or irregular quadrilateral shapes.

[0032] For all surface shapes, glass spacers can be arranged in the edge area or along the edge area, with a connecting element being arranged in at least one of the spaces between two adjacent glass spacers.

[0033] The connecting element rests directly or indirectly against the two glass spacers, thus touching and sealing them. However, it is also intended that the seal or a sealing connection between the connecting element and the respective glass spacer can be further enhanced or improved by means of EVA, a UV-curing adhesive (UV adhesive), adhesive tape, or another type of adhesive.

[0034] A further aspect of the invention comprises the method for manufacturing an insulating glass unit for multi-pane doors or glazing with a transparent edge seal and with a space between the panes, using an ethylene-vinyl acetate copolymer lamination layer or a UV-curing adhesive layer or a UV-curing bond. The insulating glass unit is provided to comprise a base pane and a cover pane and to have a circumferential edge region.In successive steps or processes, at least two glass spacers are attached to the base pane of the insulating glass unit to be created. Each spacer has an ethylene-vinyl acetate copolymer laminate layer as a semi-finished product on two opposing longitudinal surfaces facing the base pane and the cover pane (which is yet to be applied). Alternatively, the spacers may have a UV-curing adhesive or a UV-curing adhesive layer applied to both longitudinal surfaces facing the base pane and the cover pane, or the UV-curing adhesive or adhesive layer may be applied successively to the longitudinal surfaces facing the base pane and the cover pane. The spacers are attached circumferentially around the edge of the insulating glass unit. A connecting element is arranged in at least one space between the at least two glass spacers.The respective ethylene-vinyl acetate copolymer lamination layers, or the UV-curing adhesive, or the UV-curing adhesive layer extend onto this at least one connecting element. When using ethylene-vinyl acetate copolymer lamination layers, the respective ethylene-vinyl acetate copolymer lamination layers are butted together or overlap. Accordingly, the glass spacers and the at least one connecting element form a continuous frame onto which, as mentioned above, the cover pane is placed. This continuous frame thus forms the space between the base pane and the cover pane. When using ethylene-vinyl acetate copolymer lamination layers, the entire assembly is clamped or fixed, and the lamination process then takes place in a laminating oven at approximately 135 degrees Celsius.Alternatively, when using UV-curing adhesive or UV-curing adhesive layer, irradiation with UV light takes place.

[0035] This simplifies the production of insulating glass units because the few individual components—the respective glass spacers and the glass panes—require minimal manual work. Furthermore, the arrangement of these components already provides a basic stability, enabling highly precise work and thus the production of high-quality insulating glass units with a continuous transparent edge seal. The process allows for a more streamlined production flow, eliminating the need for additional energy-intensive production steps.

[0036] The use of UV-curing adhesive or a UV-curing adhesive layer allows for the sustainable and, in particular, energy-efficient and rapid production of insulating glass units. At the same time, it is possible to correct the arrangement of the individual components until the UV adhesive has cured.

[0037] Advantageous embodiments of the insulating glass element and the method are described in the dependent claims.

[0038] A key advantage of this insulating glass unit is that the base pane and the cover pane have round and / or polygonal shapes, and / or that the base pane and the cover pane are flat or curved. This allows for the production of various types and shapes of insulating glass units, thus expanding their potential applications to diverse areas with varying surfaces and shapes. For example, in addition to applications in conservatories, shopfitting, refrigerated display cases, and window and door construction, insulating glass units for multi-pane doors with transparent edge seals are also suitable for other applications.

[0039] An advantage of the insulating glass unit is that the connecting element is arranged between the end faces of two adjacent glass spacers or in the space between the end faces of two adjacent glass spacers, so that a continuation of the adjacent glass spacers is achieved and the formation of the frames is facilitated, which simplifies manufacturing and improves stability.

[0040] An advantage of the insulating glass element is that the connecting element is arranged to bridge or fill at least one of the spaces between the end faces of two adjacent glass spacers, thus avoiding complex arrangements of the glass spacers and also promoting the use and combination of any lengths and shapes of the glass spacers, which in turn promotes resource-saving production.

[0041] An advantage of the insulating glass unit is that the connecting element is arranged between the end face of a first glass spacer and a longitudinal surface of an adjacent second glass spacer, thus increasing the flexibility of the arrangement of the glass spacers with regard to their position in the insulating glass unit in relation to the further or intended use, and also keeping the design or manufacture simple.

[0042] Advantageously, the sealing and stability of the insulating glass unit are increased by having the ethylene-vinyl acetate copolymer, the UV-curing adhesive, an adhesive tape, or another adhesive at joints or interfaces between the respective connecting element and the respective glass spacer, and / or by having joints or interfaces between two glass spacers without a connecting element.

[0043] By having the lamination layer of the insulating glass unit advantageously have a transition area and arranging it butt-jointed or overlapping at this transition area, the tightness is improved.

[0044] For insulating glass units, it is advantageous if the glass spacers are preferably cut from soda-lime glass, which simplifies processing and promotes stability and a secure bond.

[0045] By grinding the glass spacers in the insulating glass unit and giving them a polished broken edge with a 0.5 mm rim, the bonding between the lamination coating and the respective spacers and the two glass panes is promoted. The lamination coating, which protrudes laterally, is distributed evenly along the rim without protruding or extending beyond it. This provides an additional surface for improved and further bonding of the EVA at the rim.

[0046] By advantageously forming a corner element with the connecting element in the insulating glass unit, whereby the end faces of the two glass spacers pointing towards the respective connecting element are aligned at an angle to each other, critical areas can be reliably bridged and manufacturing simplified.

[0047] By advantageously forming an extension element for at least one of the glass spacers in the insulating glass unit, the respective connecting element can be flexibly used at any point with the glass spacers and in different combinations and constellations.

[0048] By having at least one flag-like projection on the connecting element of the insulating glass unit, wherein the at least one flag-like projection is aligned parallel to or on or to one of the longitudinal surfaces of the respective glass spacer and is directly or indirectly in contact with the respective glass spacer, the tightness is increased on the one hand and, on the other hand, if used, the leakage of the EVA or the UV-curing adhesive or the other adhesive and / or, depending on the quantity, also the surface area for the EVA or the UV-curing adhesive or the other adhesive or adhesive tape is increased.

[0049] By having at least one flag-like projection in the space between the panes of the insulating glass unit, both the airtightness and, if used, the uncontrolled leakage of EVA, UV-curing adhesive, or other adhesives are prevented or reduced. Depending on the amount of EVA, UV-curing adhesive, other adhesive, or adhesive tape used, the surface area for the EVA, UV-curing adhesive, other adhesive, or adhesive tape is also increased.

[0050] The flag-like projection, for example, extends the respective inner surface (i.e., located within the space between the panes) and / or outer surface (i.e., located outside the space between the panes) of the connecting element. The flag-like projection has, for example, the same height as the connecting element itself and a rectangular surface that preferably rests against the respective glass spacer.

[0051] By advantageously incorporating a transparent or translucent and / or elastic and / or gas-impermeable plastic or plastic mixture or plastic composite into the connecting element of the insulating glass unit, the connecting element can be arranged or placed at any desired location and also discreetly. Visibility and transparency are thus enhanced.

[0052] By including a desiccant in the connecting element of the insulating glass unit, or by making the connecting element capable of holding a desiccant, the desiccant can still be used if necessary without having to do without the glass spacers.

[0053] By recessing at least one of the glass spacers in the insulating glass unit by 0.5 to 1.5 mm, particularly preferably 1 mm, from the edge of the base and / or cover pane, or by arranging them flush, a defined and clean finish and protrusion of the ethylene-vinyl acetate copolymer protruding between the glass spacers and the base and cover panes can be achieved at the edge of the pane and in the cavity between the panes. This means that the ethylene-vinyl acetate copolymer does not protrude beyond the edge of the pane, or, in the case of a flush arrangement, only protrudes minimally. This allows the insulating glass units to be stood upright, stored, or transported on any of their outer edges. The time-consuming rework of the insulating glass units, which involves the cumbersome removal of the protruding ethylene-vinyl acetate copolymer, is eliminated and is only necessary in the case of a flush arrangement.

[0054] Advantageously, when using UV-curing adhesive, the glass spacers can be positioned flush with the edge of the base and cover panes, as little or no UV-curing adhesive will leak between the spacers and the base and cover panes. The glass spacers can also be positioned at any desired distance from the edge of the pane.

[0055] By recessing at least one of the glass spacers from the edge of the base pane and / or cover pane between 3 mm and 15 mm or 16 and 40 mm or 41 and 60 mm in the insulating glass unit, functional elements, retaining elements or construction elements can be inserted or arranged more easily.

[0056] In the insulating glass unit, four glass spacers are provided in a rectangular surface shape, and the first two opposing glass spacers are arranged between or outside the next two opposing glass spacers or at the end faces of the next two opposing glass spacers, wherein the space between the respective end faces of at least one of the first two opposing glass spacers and the respective adjacent next two opposing glass spacers is formed, and the respective connecting element is arranged in the respective space.

[0057] In an alternative design, the respective connecting element is arranged in the space between the respective end faces of the first two opposing glass spacers and the next two adjacent opposing glass spacers.

[0058] This results in a simple and reliable arrangement of the glass spacers and the respective connecting elements.

[0059] In an insulating glass unit with a rectangular surface shape, four glass spacers are provided, the first two opposing glass spacers being arranged with their respective end faces extending to or spaced away from the edge of the pane, the other two opposing glass spacers being arranged between the first two opposing glass spacers, at least one of these other two opposing glass spacers being spaced away from the first two opposing glass spacers with its respective end faces, and the space between the respective end faces of this at least one of the other two opposing glass spacers and the respective adjacent glass spacer being formed, with the connecting element being arranged in the respective space.A reliable, transparent edge seal is created, along with a receptacle for functional elements, retaining elements, or structural elements in the area of ​​one or two opposing glass spacers.

[0060] By incorporating four glass spacers into the insulating glass unit with a rectangular surface, and by spacing the respective end faces of at least three of these spacers apart from each other and / or from the edge of the pane, and by creating a gap between the end faces of these three spacers, with the connecting element located in each gap, an insulating glass unit with maximum visibility and transparency is created, as the edge seal runs continuously around the perimeter. For example, at least two connecting elements are provided. However, four connecting elements can also be used.

[0061] The range of applications can be increased by placing at least one metal or plastic spacer between two glass spacers, between the end faces of two adjacent glass spacers, or between the longitudinal surfaces of two glass spacers, with the ethylene-vinyl acetate copolymer or UV-curing adhesive extending to the metal or plastic spacer and, if necessary, to the joints. Furthermore, in edge areas or other areas that are not visible depending on the application, or where the spacer does not obstruct or interfere with the view, the glass spacer can be omitted and a metal or plastic spacer can be used instead or in addition.The metal or plastic spacer can, for example, be arranged between two end faces of two glass spacers, or between two longitudinal faces of two adjacent glass spacers, or in some other way between two glass spacers.

[0062] By having functional, retaining, or structural elements present or usable in the area of ​​at least one of the glass spacers between the base pane and the cover pane of the insulating glass unit, for example, door hinge components or hinge receptacles, or additionally, lighting (e.g., to illuminate the floor or merchandise), or sensors (e.g., to control the lighting or to detect the door's position and warn of prolonged opening), energy sources such as accumulators or batteries can also be accommodated in this area.

[0063] By using a lamination layer in the form of an ethylene-vinyl acetate copolymer in the form of a film with a thickness of 0.38 mm or a multiple thereof, the process facilitates easy processing and also promotes full-surface and complete cross-linking at the connection points between the spacers and the glass panes.

[0064] Advantageously, in this process, an ethylene-vinyl acetate copolymer laminating layer is used on the glass spacers and the respective connecting element, and between the glass panes and the glass spacers and the respective connecting element, either as a film or as a multi-crosslinking agent in granular form. This liquid form is heated, ensuring that the connection points between the respective spacers and the two glass panes are completely filled with the laminating layer during lamination, thus promoting complete crosslinking at the connection points.

[0065] By introducing the ethylene-vinyl acetate copolymer, the UV-curing adhesive, an adhesive tape, or another adhesive into the joints or interfaces between the respective connecting element and the respective glass spacer and / or into the joints or interfaces between two glass spacers without a connecting element, the stability and tightness are increased and the transparency is improved.

[0066] By arranging the connecting element between the end faces of two adjacent glass spacers or in the space between the end faces of two adjacent glass spacers, and / or by arranging the connecting element to bridge or fill at least one of the spaces between the end faces of two adjacent glass spacers, and / or by arranging the connecting element between the end face of a first glass spacer and a longitudinal surface of an adjacent second glass spacer, the production of the transparent edge seal in particular can be simplified.

[0067] By arranging at least one metal or plastic spacer between two glass spacers, or between the end faces of two adjacent glass spacers, or between the longitudinal faces of two glass spacers, and by extending the ethylene-vinyl acetate copolymer or UV-curing adhesive onto the metal or plastic spacer, a combination of glass spacers and metal or plastic spacers can be created, thereby eliminating the need for a glass spacer and using a metal or plastic spacer instead or in addition.

[0068] By recessing at least one of the glass spacers from the edge of the base and / or cover pane by 0.5 to 1.5 mm, particularly preferably 1 mm, or by positioning them flush, the time-consuming rework can be eliminated. Furthermore, this facilitates the placement of the insulating glass units on the horizontal or transverse edge of the pane without indenting or damaging the extruded ethylene-vinyl acetate copolymer lamination layer. If necessary, the glass spacer can be positioned flush, thus prioritizing the placement of the glass spacer over rework.

[0069] The process is advantageously facilitated by the use of UV-curing adhesive, which allows the glass spacers to be positioned flush with the edge of the base and cover panes, as little or no UV-curing adhesive seeps out between the glass spacers and the base and cover panes. Likewise, any desired distance to the edge of the pane can be selected.

[0070] By placing at least one of the glass spacers recessed between 3 mm and 15 mm or 16 and 40 mm or 41 and 60 mm from the edge of the base pane and / or cover pane in the process, functional elements, retaining elements or structural elements can be inserted in the area of ​​the recessed glass spacer.

[0071] In the method, with a rectangular surface shape and four glass spacers, two opposing glass spacers are arranged between or outside the other two opposing glass spacers, or at the end faces of the other two opposing glass spacers, wherein the space is formed between the respective end faces of at least one of the first two opposing glass spacers and the respective adjacent two further opposing glass spacers, wherein the respective connecting element is arranged in the respective space, or, with a rectangular surface shape and four glass spacers, the first two opposing glass spacers are arranged with their respective end faces extending to the edge of the pane or spaced apart from the edge of the pane.wherein the other two opposing glass spacers are arranged between the first two opposing glass spacers, wherein at least one of these other two opposing glass spacers is arranged with its respective end faces spaced apart from the first two opposing glass spacers, and the space between the respective end faces and the respective adjacent glass spacer is formed, wherein the respective connecting element is arranged in the respective space, or that, in the case of a rectangular surface shape and four glass spacers, the respective end faces of at least three glass spacers are arranged with a space between each other and / or the edge of the pane, and the space between the end faces of the at least three glass spacers is formed, wherein the respective connecting element is arranged in the respective space.The production process, especially of the transparent edge seal, can be adapted and simplified as needed.

[0072] An advantage of the conventional method is that, after completion of the lamination or bonding process, the space between the panes of the insulating glass unit is filled with a noble gas via at least one connecting element through a through-opening, and the through-opening is then closed, thereby preventing or significantly reducing the presence or penetration of moisture and thus condensation processes in later use, even without desiccants.

[0073] By inserting and / or mounting or bonding functional elements, retaining elements or structural elements into the area of ​​at least one of the glass spacers between the base pane and the cover pane during the process, manufacturing can be made more efficient and the quality of the final product can be increased, as subsequent rework can be avoided or minimized.

[0074] Several embodiments of the invention are shown in the drawings and are described in more detail below. They show: Fig. 1a a connecting element as a corner element in one design in two different perspectives, Fig. 1b a connecting element as a corner element in section view, Fig. 1c Connecting element as a corner element with through opening in sectional view, Fig. 2a A detailed view of a corner of an insulating glass unit with glass spacers and a connecting element as a corner element.

[0075] The Figure 1a shows a connecting element 2 as corner element 2a in two different views, as well as the Figure 1bas a sectional view. The illustrated connecting element 2 has two flag-like projections 9 on two mutually perpendicular outer surfaces 10, each facing a glass spacer (not shown) or its end faces 11, the respective flag-like projection 9 being parallel to the respective glass spacer (not shown). The end faces 11 of the two glass spacers 1 facing the respective connecting element 2 are correspondingly perpendicular to each other, in this specific example, at right angles. The connecting element 2 preferably has the same height as the glass spacer (not shown). The area between the flag-like projections 9 preferably corresponds to the width of the glass spacer (not shown).

[0076] The Figure 1cFigure 2 shows a sectional view of the connecting element 2 as corner element 2a, wherein the connecting element 2 has a through opening 8 to the space between the panes (not shown).

[0077] As an alternative to a through-opening 8, the connecting element 2 in this area can include a desiccant or contain a desiccant in the connecting element 2.

[0078] Preferably, the connecting element 2 is made of a transparent or translucent and elastic as well as gas-impermeable plastic or plastic composite, so that it is now minimally or not perceived.

[0079] The Figures 2a and 2bFigure 1 shows a detailed view of a corner of an insulating glass unit for multi-pane doors or glazing with a transparent edge seal and a space between the panes 5. The insulating glass unit comprises a rectangular or square base pane 4a and a cover pane 4b and has a surrounding edge region 12. Glass spacers 1 are arranged around the perimeter of the edge region 12 between the base pane 4a and the cover pane 4b. Thus, four glass spacers 1 are present in the case of a rectangular surface shape. The respective end faces 11 of at least three or all four glass spacers 1 are spaced apart from each other and from the edge of the pane 13. A space 6 is provided between the end faces 11 of each of the at least three glass spacers 1. A connecting element 2 is arranged in the space 6 formed between the adjacent glass spacers 1 or their end faces 11.The connecting element 2 is indirectly in contact with the two glass spacers 1 or the end faces 11 of the glass spacers 1. A lamination layer 3 in the form of an ethylene-vinyl acetate copolymer 3 is present between the base plate 4a and the glass spacers 1 and the at least one connecting element 2, and between the glass spacers 1 and the at least one connecting element 2 and the cover plate 4b.

[0080] The lamination layer 3 has a transition area 7 and is arranged overlapping at this transition area 7. In this specific example, the transition area 7 is located at the connecting element 2. Depending on the surface shape of the base pane 4a and cover pane 4b, the transition area 7 can also be located in the area of ​​one of the glass spacers 1.

[0081] The joints or interfaces between the connecting element 2 and the respective glass spacer 1 preferably consist of the ethylene-vinyl acetate copolymer 3. However, an adhesive tape or an adhesive can also be used.

[0082] For example, if in an embodiment not shown two glass spacers 1 are arranged without a gap 6 and without a connecting element 2, the ethylene-vinyl acetate copolymer 3 or an adhesive tape or an adhesive is present in the respective joint or at the respective interface between the two glass spacers 1.

[0083] As an alternative to the ethylene-vinyl acetate copolymer 3, the at least two glass spacers 1 and the at least one connecting element 2 are bonded or joined to the base plate 4a and the cover plate 4b using a UV-curing adhesive 14 [not shown]. Likewise, the joints between the glass spacers 1 and the joints between the glass spacers 1 and the at least one connecting element 2 can be bonded or joined using a UV-curing adhesive 14 [not shown].

[0084] The glass spacers 1 are preferably cut and ground from soda-lime glass and have a polished fracture edge with a rim of 0.5 mm.

[0085] Depending on the requirements, at least one or two or all of the glass spacers 1 parallel to each other can be recessed or flush with the edge 13 of the base pane 4a and / or cover pane 4b by between 0.5 and 1.5 mm, particularly preferably 1 mm.

[0086] The illustrated connecting element 2 has two flag-like projections 9 at each glass spacer 1 or at each end face 11 of a glass spacer 1. The flag-like projections 9 are rectangular in shape. Glass spacers 1 are arranged or inserted between the two flag-like projections 9. The flag-like projections 9 are aligned parallel to the respective glass spacer 1 and abut against it. The connecting element 2 has the same height as the glass spacer 1. The area between the flag-like projections 9 preferably corresponds to the width of the glass spacer 1.

[0087] In Figure 2aIn this specific example, the connecting element 2 is closed, meaning there is no through-opening 8 into the space between the panes 5. However, the through-opening 8 could be present in another connecting element 2, which is not shown.

[0088] However, the closed connecting element 2 can also include a desiccant (not shown), for example in a chamber (not shown) that is open or continuous to the space between the disks 5.

[0089] In Figure 2b In this specific example, the connecting element 2 has the through-opening 8. This extends from outside the insulating glass unit into the space between the panes 5.

[0090] The through-opening 8 allows for filling, evacuation, pressure equalization during lamination, or the escape of air during filling.

[0091] In the Figure 3aThe connecting element 2 is shown in an alternative embodiment as an extension element 2 in two different perspectives and in a sectional view. The connecting element 2 shown has two flag-like projections 9 at only one end face 11 of a glass spacer 1. The flag-like projections 9 are rectangular in shape. The glass spacer 1 is arranged or inserted between the two flag-like projections 9. The flag-like projections 9 are aligned parallel to the glass spacer 1 and abut the respective glass spacer 1. The respective connecting element 2 has the same height as the glass spacer 1. The area between the flag-like projections 9 preferably corresponds to the width of the glass spacer 1. The side of the connecting element 2 opposite the flag-like projections 9 is designed to be placed against a longitudinal surface of another, adjacent glass spacer 1.

[0092] However, it is not excluded that the opposite side of the connecting element 2 may also be or could be attached to an end face 11 of a glass spacer 1, in which case the flag-like projections 9 would be absent. The respective joint or interface between the respective connecting element 2 and the respective glass spacer 1 would feature the ethylene-vinyl acetate copolymer 3, an adhesive tape, or an adhesive.

[0093] It is conceivable to use the connecting element 2 as an extension element 2 for extending glass spacers 1. Preferably, the connecting element 2 would have one or two flag-like projections 9 at each of its end faces 11 where they meet the connecting element 2.

[0094] In addition to and deviating from Figure 3a is in Figure 3bThe connecting element 2 is shown in an alternative version as extension element 2b in two different perspectives and in a sectional view, in which the extension element 2b has a through opening 8 from outside the insulating glass element into the space between the panes 5.

[0095] In the alternative embodiment of the connecting element 2 as extension element 2b, the closed connecting element 2 can also include a desiccant (not shown), for example in a chamber (not shown) that is open to or through the space between the disks 5.

[0096] The Figures 4a to 4dFigure 1 shows a detailed view of a corner of an insulating glass unit for multi-pane doors or glazing with a transparent edge seal and a space between the panes 5. The insulating glass unit comprises a rectangular or square base pane 4a and a cover pane 4b and has a surrounding edge region 12. Glass spacers 1 are arranged around the perimeter of the edge region 12 between the base pane 4a and the cover pane 4b. Thus, four glass spacers 1 are present in the case of a rectangular shape. Two opposing glass spacers 1, with their respective end faces 11, extend to the edge 13 of the pane. The other two opposing glass spacers 1 are arranged between the first two opposing glass spacers 1.At least one of the two opposing glass spacers 1 is arranged with its end face 11 spaced apart from the first two opposing glass spacers 1. A gap 6 is formed between the end face 11 of this other opposing glass spacer 1 and the adjacent glass spacer 1. The connecting element 2 is arranged in the respective gap 6.

[0097] Between the base plate 4a and the glass spacers 1 and the at least one connecting element 2, and between the glass spacers 1 and the at least one connecting element 2 and the cover plate 4b, a lamination layer 3 in the form of an ethylene-vinyl acetate copolymer 3 is present, as shown in Figures 4a and 4b is shown.

[0098] As an alternative to the ethylene-vinyl acetate copolymer 3, the at least two glass spacers 1 and the at least one connecting element 2 are bonded or joined to the base plate 4a and the cover plate 4b by means of a UV-curing adhesive 14, as shown in Figures 4c and 4d The joints between glass spacers 1 and the joints between the glass spacers 1 and the at least one connecting element 2 are also bonded or joined by means of a UV-curing adhesive 14.

[0099] The lamination layer 3 has a transition area 7 and is arranged overlapping at this transition area 7. In this specific example, the transition area 7 is located in the area of ​​the glass spacer 1, which extends to the edge 13 of the pane with its end face 11 shown. Depending on the surface shape of the base pane 4a and cover pane 4b, the transition area 7 can also be located in the area of ​​one of the glass spacers 1 or one of the connecting elements 2.

[0100] In Figure 4a In this specific example, the connecting element 2 is closed as extension element 2b, meaning there is no through-opening 8 into the space between the panes 5. However, the through-opening 8 may be present in another connecting element 2 not shown.

[0101] In Figure 4bIn this specific example, the connecting element 2, as extension element 2b, has the through-opening 8. This extends from outside the insulating glass unit into the space between the panes 5. In this design, filling or evacuation, pressure equalization during lamination, or the escape of air during filling can take place via the through-opening 8.

[0102] In Figure 5 Figure 1 shows an embodiment of a rectangular insulating glass unit, in which, in addition to and deviating from the designs and illustrations of the Figures 4a and 4bFour glass spacers 1 are shown. The first two opposing, vertically shown glass spacers 1 are arranged with their respective end faces 11 extending to the edge of the pane 13. The other two opposing, horizontally shown glass spacers 1 are arranged between the first two opposing glass spacers 1 and spaced apart from the edge of the pane 13. In the case of the other two opposing glass spacers 1 shown below, the respective end faces 11 are spaced apart from the first two opposing, vertically shown glass spacers 1. The space 6 is formed between the respective end faces 11 of this other two opposing glass spacers 1 shown below and the longitudinal surfaces of the respective adjacent, vertically shown glass spacers 1.In each of the respective spaces 6, the connecting element 2 is arranged as an extension element 2b.

[0103] In the case of the other two opposing glass spacers 1 shown above, the respective end faces 11 are arranged up to the first two opposing vertically depicted glass spacers 1. This other two opposing glass spacer 1 shown above is also arranged at a distance from the edge of the pane 13.

[0104] In area 6 of the glass spacers 1 arranged at a distance from the edge of the pane 13, functional elements or retaining elements or construction elements can be inserted between the base pane 4a and the cover pane 4b.

[0105] The connecting element 2 shown on the left, as extension element 2b, has the through opening 8. The connecting element 2 shown on the right, as extension element 2b, does not have a through opening 8.

[0106] The connecting elements 2 each have a flag-like projection 9, which is aligned parallel to the respective glass spacer 1 and rests against the respective glass spacer 1, and is arranged in the cavity 5 between the panes. The outer surface 10 of the connecting elements 2, which lies outside the cavity 5 between the panes, is in line with the longitudinal surface of the lower glass spacer 1 located between them.

[0107] The joints or interfaces between the respective connecting element 2 and the respective glass spacers 1 and the joints or interfaces between two glass spacers 1 without connecting element 2 feature the ethylene-vinyl acetate copolymer 3.

[0108] Alternatively, a UV-curing adhesive 14 [not shown] can be present in the joints or interfaces between the respective connecting element 2 and the respective glass spacers 1, and in the joints or interfaces between two glass spacers 1 without a connecting element 2, with which the joints or interfaces are filled or sealed. Likewise, the at least two glass spacers 1 and the at least one connecting element 2 can be bonded or joined to the base plate 4a and the cover plate 4b by means of a UV-curing adhesive 14 [not shown].

[0109] In the embodiment according to the Figure 6The figure shows a round, specifically oval, insulating glass unit, i.e., an insulating glass unit without corners. In addition to and deviating from the above descriptions of the basic structure, two curved glass spacers 2 are present. A connecting element 2 is arranged between the end faces 11 of each of the two adjacent glass spacers 1, resulting in two glass spacers 2 and two connecting elements 2. Both connecting elements 2 have a passage opening 8 from outside the insulating glass unit into the cavity 5 between the panes. Each connecting element 2 has two flag-like projections 9, which are oriented towards the longitudinal surface of the respective glass spacer 1, rest against the spacer 1, and are located in the cavity 5 between the panes.The outer surface 10 of the connecting elements 2, which lies outside the space between the panes 5, is approximately in line with the longitudinal surface of the lower glass spacer 1 located between them.

[0110] Alternatively to ethylene-vinyl acetate copolymer 3 are

[0111] The at least two glass spacers 1 and the at least one connecting element 2 can be connected or bonded to the base plate 4a and the cover plate 4b by means of ethylene-vinyl acetate copolymers 3 or by means of a UV-curing adhesive 14 [not shown]. Likewise, the joints between glass spacers 1 and the joints between the glass spacers 1 and the at least one connecting element 2 can be connected or bonded by means of ethylene-vinyl acetate copolymers 3 or by means of a UV-curing adhesive 14 [not shown].

[0112] The inventive method for manufacturing an insulating glass unit for multi-pane doors or glazing with a transparent edge seal and with a space between the panes 5 using an ethylene-vinyl acetate copolymer lamination layer or a UV-curing adhesive layer 14 or a UV-curing bond 14, wherein the insulating glass unit comprises a base pane 4a and a cover pane 4b and has a circumferential edge region 12, provides thatthat at least two glass spacers 1, each with an ethylene-vinyl acetate copolymer lamination layer 3 adhering to two opposing longitudinal surfaces facing the base pane 4a and the cover pane 4b, are first attached to the base pane 4a of the insulating glass unit as a semi-finished product or with the UV-curing adhesive 14 or adhesive layer 14 on the longitudinal surfaces of the glass spacers 1 facing the base pane 4a and the cover pane 4b, circumferentially around the edge region 12 or along the edge region 12 of the insulating glass unit. Depending on the surface shape, which can be round (i.e., without corners), square, or a combination of round and square, two, three,Four or more glass spacers 1 are considered. A connecting element 2 is arranged in at least one of the spaces 6 between the at least two glass spacers 1. Thus, a connecting element 2 can be arranged in each space 6 or only in certain spaces 6. Here, the respective ethylene-vinyl acetate copolymer lamination layers 3 or the UV-curing adhesive 14 or the UV-curing adhesive layer 14 extends onto the respective,At least one connecting element 2. When using the ethylene-vinyl acetate copolymer laminating layers (3), the respective ethylene-vinyl acetate copolymer laminating layers are butted together or overlap. The glass spacers 1 and the at least one connecting element 2 thus form a continuous frame. The cover pane 4b is placed on this frame. The continuous frame thus forms the space between the panes 5 between the base pane 4a and the cover pane 4b. The entire assembly is then clamped or fixed. The lamination process then takes place at approximately 135 degrees Celsius in a laminating oven. When using the UV-curing adhesive 14 or the UV-curing adhesive layer 14, irradiation with UV light is carried out.

[0113] After completion of the lamination process using conventional methods or the bonding process using UV light, the cavity 5 of the insulating glass unit is filled with an inert gas via at least one connecting element 2 through a passage 8 or through a passage 8 in at least one of the glass spacers 1. The passage 8 is then sealed.

[0114] Preferably, the laminating layer 3 is used in the form of an ethylene-vinyl acetate copolymer 3 in the form of a film with a thickness of 0.38 mm or a multiple thereof. In addition to an ethylene-vinyl acetate copolymer laminating layer 3 on the glass spacers 1 and the respective connecting element 2, and between the glass panes 4 and the glass spacers 1 and the respective connecting element 2 as a film, the EVA 3 can also be used as a multi-curing agent in granular form following heating in liquid form.

[0115] Furthermore, EVA 3 or UV-curing adhesive 14 can be applied to joints or interfaces between the respective connecting element 2 and the respective glass spacer 1 and / or to joints or interfaces between two glass spacers 1 without a connecting element 2. Alternatively, adhesive tape or another adhesive can be applied to the joints or interfaces.

[0116] Depending on the embodiment of the insulating glass element, the connecting element 2 is arranged in the space 6 between the end faces 11 of two adjacent glass spacers 1.

[0117] Alternatively or additionally, the connecting element 2 is arranged to bridge or fill at least one of the spaces 6 between the end faces 11 of two adjacent glass spacers 1.

[0118] However, it is also provided that the connecting element 2 is arranged between the end face 11 of a first of the glass spacers 1 and a longitudinal surface of an adjacent second of the glass spacers 1.

[0120] The glass spacer 1 can also be placed or arranged flush with the edge 13 of the base pane 4a and / or cover pane. This is particularly possible when using UV-curing adhesive 14, as little or no adhesive squeezes out laterally between the glass spacer 1 and the base pane 4a and / or cover pane 4b.

[0121] For example, to accommodate functional elements, retaining elements or structural elements, at least one of the glass spacers 1 is set back from the edge of the pane 13 of the base pane 4a and / or cover pane 4b between 3 mm and 15 mm or 16 and 40 mm or 41 and 60 mm from the edge of the pane 13 to provide the necessary clearance.

[0122] In the case of a rectangular surface shape and four glass spacers, two opposing glass spacers 1 are arranged between or outside the other two opposing glass spacers 1, or at the end faces 11 of the other two opposing glass spacers 1. A gap 6 is formed between the respective end faces 11 of at least one of the first two opposing glass spacers 1 and the respective adjacent two opposing glass spacers 1. The respective connecting element 2 is arranged in the respective gap 6.

[0123] In an alternative embodiment with a rectangular surface shape and four glass spacers 1, the first two opposing glass spacers 1 are arranged with their respective end faces 11 extending to the edge of the pane 13, or alternatively, spaced apart from the edge of the pane 13. The other two opposing glass spacers 1 are arranged between the first two opposing glass spacers 1. At least one of these other two opposing glass spacers 1 is spaced apart from the first two opposing glass spacers 1 with its respective end faces 11. A gap 6 is formed between the respective end faces 11 of this at least one of the other two opposing glass spacers 1 and the adjacent glass spacer 1. The respective connecting element 2 is arranged in the respective gap 6.

[0124] In another alternative embodiment with a rectangular surface shape and four glass spacers 1, the respective end faces 11 of at least three glass spacers 1 are spaced apart from each other and / or from the edge of the pane 13. A gap 6 is formed between the end faces 11 of each of the at least three glass spacers 1. The respective connecting element 2 is arranged in this gap 6.
