Definitions
- the invention relates to an insulating glazing unit which has at least two glass panes and a spacer and sealing profile running between them near their edges, with at least one RFID transponder being attached to the insulating glazing unit as an identification element.
- the invention also relates to glazing with a metal frame and an insulating glazing unit inserted into the frame, with the frame encompassing the edges of the insulating glazing unit and at the same time covering the RFID transponder or transponders.
- the glazing is intended in particular to form facade glazing, a window, a door or an interior partition with a corresponding structure.
- IGU insulating glazing units
- Such insulating glazing units represent mass-produced, dispatched and also independently traded products which should be clearly identifiable on their way to an end product and possibly also during its maintenance and repair.
- the identifying mark should be invisible from both the inside and outside of the finished window, door or curtain wall.
- the marking should be "readable” from a distance of at least 30 cm.
- the marking should be as forgery-proof as possible, i.e. it should not be easily overwritten or copied.
- RFID transponders are known, for example, from WO 2016/198914 A1.
- Such insulating glazing units are disclosed, for example, in WO 00/36261 A1, WO 2020/156870 A1, WO 2020/156871 A1 or WO 2007/137719 A1.
- EP 2 230 626 A1 discloses RFID transponders for identifying solid and composite solid material panels.
- Such an RFID transponder can be protected with a password so that it cannot be overwritten or its radio capability destroyed without considerable effort.
- Known insulating glazing units provided with RFID transponders cannot therefore be used without further ado in metal frame constructions. This reduces the potential area of application of the glazing units marked in this way and thus the acceptance of the corresponding marking solutions by manufacturers and users.
- the invention is therefore based on the object of providing an improved insulating glazing unit for glazing with frame constructions which consist at least to a considerable extent of metal and which also ensures that the above requirements are met in such installation situations.
- this object is achieved by an insulating glazing unit having the features of claim 1 .
- it is solved by glazing with an insulating glazing unit according to the invention.
- the invention comprises an insulating glazing unit, comprising: at least one spacer, which is formed circumferentially into a spacer frame and delimits an interior area, a first glass pane, which is arranged on a first pane contact surface of the spacer frame and a second glass pane, which is arranged on a second pane contact surface of the spacer frame, and the glass panes protrude beyond the spacer frame and form an outer area which is at least partially, preferably completely, filled with a sealing element, with at least one RFID transponder being arranged in the outer area or in the outer edge area of the glass panes, and the RFID transponder containing a slot antenna .
- At least one RFID transponder is arranged in the outside area (between the glass panes and around the spacer frame) or in the outer edge area of the glass panes.
- the outer edge area of the glass panes is formed by the end faces of the glass panes and by an area of the outer surfaces of the glass panes close to the end faces.
- a further aspect of the invention comprises glazing, in particular facade glazing, a window, a door or an interior partition, comprising: a frame and an insulating glazing unit according to the invention arranged in the frame.
- the RFID transponder can be arranged directly on the insulating glazing unit or can be connected indirectly to the insulating glazing unit via the frame.
- the frame comprises a metallic first frame element, a metallic second frame element and a polymeric third frame element connecting the frame elements at least in sections and preferably completely circumferentially or consists of them.
- the frame encompasses the end face of the insulating glazing unit, preferably in a U-shape, and at the same time covers the RFID transponder or transponders in the viewing direction through the glass panes.
- the legs of the first and second frame elements are usually designed in such a way that they at least completely cover the outer area and the spacer frame in the direction of vision through the insulating glazing unit.
- the invention is based on the following finding: according to the current state of the art, transponders with simple dipole structures are used as antennas for UHF-RFID applications. Under far-field conditions, these usually show good reception and transmission properties.
- one of the main reasons for the poor performance is in the main direction of the nearby metallic parts of the frame or spacer in relation to the dipole antenna of the RFID transponder.
- the component of the electrical field (hereinafter E-field) of the dipole antenna of an RFID transponder according to the prior art is aligned in the near-field area parallel to the extension direction (longitudinal direction) of the dipole antenna. Due to the usual length of the dipole antenna of several centimeters, it must be arranged parallel to the metal frame or the spacer when installed in the area covered by the glazing frame. That is, the nearby parts of the frame and the electric field of the dipole antenna are parallel, so the E-field can be absorbed by the frame.
- the signal is then "trapped" in the frame and may not be radiated, or only attenuated, to the outside of the glazing where the RFID reader would be located.
- Slot antennas also have an elongated shape.
- the E-field typically runs perpendicular to the direction in which the slot antenna extends. This means that the E field of the slot antenna runs orthogonally to the E field of a dipole antenna.
- the H fields If an RFID transponder according to the invention with a slot antenna is arranged in a glazing according to the invention in the usual and, for geometric reasons, the only possible orientation (ie with the direction of extension parallel to the adjacent frame or spacer), the radiated E-field in the near field area is orthogonal to the direction of extension of frame or spacer. In such a configuration, the E-field is only slightly absorbed or attenuated. As a result, the E field radiated by the slot antenna can escape much more easily from the cavity (which is formed by the facade frame and spacer) and the RFID transponder according to the invention can be read from a greater distance.
- the invention has arisen as a result of extensive experimental studies undertaken on insulating glazing units and glazings having the above-mentioned basic structure.
- Advantageous spacers consist of a hollow profile filled with a drying agent, which consists of metal or is coated at least in sections with a metal foil or metalized foil, and on the outer surface of the spacer (hereinafter referred to as the outer surface of the spacer) a (also circumferential) sealing element is upset.
- the inventors have in particular carried out investigations into insulating glazing units embedded in metallic frames, in which the frame consists of two metallic and therefore electrically conductive frame elements which are connected via a polymeric and electrically insulating frame element.
- Such frames made of two metallic frame elements, which are connected by a polymer frame element are particularly advantageous since the polymer frame element significantly reduces heat transfer from the first frame element to the second frame element and thus, for example, from an exterior side to an interior side.
- Elastomer profiles are arranged between the outer sides of the glass panes and the inner sides of the adjacent metal frame elements, which seal the glazing and fix the glass panes.
- the RFID transponder contains RFID electronics that are galvanically connected or electromagnetically coupled to a slot antenna.
- Electromagnetically coupled means that the slot antenna and the RFID transponder are coupled by an electromagnetic field, i.e. are connected both capacitively and inductively and preferably not galvanically.
- Such designs can be arranged particularly well in the elongated and strip-shaped outer area along the spacer and between the glass panes, on the end faces of the glass panes or on the outer surfaces of the glass panes within the frame.
- Slot antennas are known per se to a person skilled in the art, for example from DE894573.
- the slot antenna according to the invention contains at least one base body made of an electrically conductive material.
- the base body is preferably in the form of a plate or film, particularly preferably with a rectangular base area (length x width).
- the base body has at least one, preferably precisely one, slit-shaped recess, which is called “slit” for short below.
- the slit-shaped recess is essentially rectangular.
- the slot forms an open passage along the thickness direction (that is, the smallest dimension of the body) from the top of the body to its bottom. The slot is completely surrounded by the base body in the area (ie in the other dimensions).
- the base body contains a self-supporting metal foil, preferably made of aluminum, an aluminum alloy, copper, silver or high-grade steel or consists of it.
- Preferred metal foils have a thickness of 0.02 mm to 0.5 mm and in particular 0.09 mm to 0.3 mm.
- Such base bodies for slot antennas can be easily integrated into the insulating glazing unit and can also be produced easily and inexpensively.
- the metal foil can also be stabilized by a polymer foil or electrically insulated on one or both sides.
- the slit is preferably a recess only in the metal foil or in metal and polymer foil.
- the base body of the slot antenna contains or consists of a metalized polymer film with a preferred metalization made of aluminum, an aluminum alloy, copper, silver or stainless steel.
- Preferred metal layers have a thickness of 10 ⁇ m to 200 ⁇ m.
- the slot is advantageously a recess only in the metallization.
- Such base bodies can also be easily integrated into the insulating glazing unit and can also be produced easily and inexpensively.
- the preferred lengths and widths of the slot antenna i.e. the length LG and the width BG of the base body and the length LS and the width BS of the slot and the position of the slot within the base body depend on the operating frequency of the RFID transponder and the respective installation situation away.
- the length LG of the base body ie the length parallel to the extension direction of the slot antenna, is advantageously from 25 mm to 200 mm, preferably from 40 mm to 170 mm and in particular from 80 mm to 150 mm.
- the width BG of the base body ie the length transverse to the direction of extension of the slot antenna, is advantageously from 10 mm to 80 mm, preferably from 12 mm to 40 mm and in particular from 15 mm to 30 mm.
- the length LS of the slot ie the length parallel to the extension direction of the slot antenna, is advantageously from 20 mm to 180 mm, preferably from 35 mm to 160 mm and in particular from 70 mm to 140 mm.
- the width BS of the slot ie the length transverse to the extension direction of the slot antenna, is from 0.2 mm to 20 mm, preferably from 1 mm to 10 mm and in particular from 2 mm to 5 mm.
- the RFID electronics are preferably arranged centrally with respect to the extension direction of the slot or in one of the end regions of the slot or somewhere in between and are galvanically connected to the base body and/or electromagnetically coupled.
- the choice of the position of the RFID electronics can be used to optimize the impedance matching between the RFID electronics and the antenna.
- the radio wavelengths used in such RFID transponder systems are usually in the UHF range at 865-869 MHz (including European frequencies) or 902-928 MHz (US American and other frequency bands) or the SHF at 2.45 GHz and 5.8GHz.
- the approved frequencies for UHF RFID transponders differ regionally for Asia, Europe and America and are coordinated by the ITU.
- the slot antenna according to the invention can be coupled in sections with a metal body, such as a metal spacer or a metal foil or a metalized foil on the spacer.
- a strip of the base body is preferably brought between the slot and the border of the base body in the immediate vicinity or in contact with the metal body, with the strip of the base body opposite the slot and the slot itself being arranged as far away as possible.
- a strip of the base body can be arranged on the metallic or metallized spacer and the slot and the opposite strip of the base body can be arranged angled at an angle of about 90° on the inner surface of one of the glass panes.
- the slot antenna can be arranged on a dielectric carrier element, particularly preferably a polymer carrier element.
- the thickness of the support element is adapted to the material and in particular to the dielectric constant of the support element and to the geometry of the slot antenna.
- the slot antennas together with the RFID electronics per se can be arranged on a dielectric and, for example, polymer carrier layer, which significantly simplifies assembly and prefabrication.
- an insulating glazing unit can have a number of RFID transponders, in particular in the edge or outer areas of the various sides (top, bottom, right, left) of the insulating glazing. As a rule, this is necessary in the case of insulating glazing according to the prior art with only short ranges of the RFID transponders in order to quickly find an RFID signal and quickly identify the insulating glazing unit. As a result of the inventive increase in the range of the RFID transponders, exactly one or a few RFID transponders per insulating glazing are usually sufficient.
- the slot antenna is arranged at least in sections on the end face of the insulating glazing unit.
- it can preferably be arranged on a section of an end face of one of the glass panes and/or on the outside of the outer area, for example on the outer surface of the sealing element.
- the slot antenna can also be arranged in sections within the outer area and in particular reach into the sealing element.
- the slot antenna and/or the complete RFID transponder can be completely embedded within the sealing element.
- the slot antenna can also be arranged on at least one of the two end faces of the glass panes and on the outside of the outer area lying in between or inside the outer area.
- the slot antenna or the entire RFID transponder is arranged on one of the outer surfaces of one of the glass panes.
- the distance between the slot antenna and the (metallic) frame element depends in particular on the thickness of the elastomer profile, which is, for example, 6 mm to 7 mm.
- the RFID transponder is arranged, preferably directly, on the outside of the spacer and in particular is glued to it.
- the RFID transponder is arranged, preferably directly, on one of the glass panes and in particular is glued to it. It goes without saying that the RFID transponder can also be arranged within the material of the sealing element, for example by being placed in the still liquid sealing element and subsequent hardening or solidification.
- the RFID transponder is arranged in the outside area, formed by the glass panes protruding over the spacer frame.
- the RFID transponder is particularly preferably arranged directly on the outer surface of the spacer and/or on the inner surface of one of the glass panes.
- the RFID transponder can be placed in the middle of the outside area, i.e. without direct contact with the outer surface of the spacer and without direct contact with the inner surfaces of the glass panes.
- the RFID transponder according to the invention is preferably arranged partially or completely within the sealing element.
- the RFID transponder is arranged on an outer surface of one of the glass panes, preferably at a distance of no more than 10 mm, particularly preferably no more than 5 mm and in particular no more than 3 mm from the adjacent face of the respective glass pane. It goes without saying that several RFID transponders can also be arranged at different positions mentioned above.

- the insulating glazing units as well as the glazing and the individual components are each denoted by the same or similar reference numbers, regardless of the fact that the specific designs differ.
- FIG. 1A shows an edge region of an insulating glazing unit 1 in cross section.
- the insulating glazing unit 1 comprises two glass panes 4a and 4b. These are held at a predetermined distance by a spacer 5 placed between the glass panes 4a, 4b near the end face 14 of the insulating glazing unit 1.
- the base body of the spacer 5 consists, for example, of glass fiber reinforced styrene acrylonitrile (SAN).
- FIG. 1B shows a schematic plan view of the insulating glazing unit 1 in a viewing direction that is identified by the arrow A in FIG. 1A.
- FIG. 1B therefore shows the second glass pane 4b on top.
- a plurality of spacers 5 are guided along the side edges of the glass panes 4a, 4b and form a spacer frame 5'.
- the pane contact surfaces 5.1, 5.2 of the spacers 5, i.e. the contact surfaces of the spacers 5 to the glass panes 4a, 4b, are each glued to the glass panes 4a or 4b and thereby mechanically fixed and sealed.
- the adhesive connection consists, for example, of polyisobutylene or butyl rubber.
- the inner surface 5.4 of the spacer frame 5' delimits an inner area 12 together with the glass panes 4a, 4b.
- the spacer 5 is usually hollow (not shown) and filled with a desiccant (not shown) which penetrates into the inner area 12 via small openings on the inside (also not shown). binds moisture.
- the desiccant contains, for example, molecular sieves such as natural and/or synthetic zeolites.
- the inner area 12 between the glass panes 4a and 4b is filled, for example, with an inert gas such as argon.
- the glass panes 4a, 4b generally protrude beyond the spacer frame 5' on all sides, so that the outer surface 5.3 of the spacer 5 and the outer sections of the glass panes 4a, 4b form an outer area 13.
- a sealing element (sealing profile) 6 is introduced in this outer area 13 of the insulating glazing unit 1 between the glass sheets 4a and 4b and outside the spacer 5 .
- This is shown here in simplified form in one piece. In practice, it usually comprises two components, one of which seals the contact surface between the spacer 5 and the glass panes 4a, 4b and protects it from the ingress of moisture and external influences from the outside. This can be identical to or combined with the adhesive surfaces between spacer 5 and glass panes 4a, 4b.
- the second component of the sealing element 6 additionally seals and mechanically stabilizes the insulating glazing unit 1 .
- the sealing element 6 is formed, for example, from an organic polysulfide.
- an insulating film 11 is applied, for example, which reduces the heat transfer through the polymeric spacer 5 into the inner area 12.
- the insulating film 11 can be attached to the polymeric spacer 5 with a polyurethane hot-melt adhesive, for example.
- the insulating film 11 contains, for example, three polymer layers made of polyethylene terephthalate with a thickness of 12 ⁇ m and three metallic layers made of aluminum with a thickness of 50 nm. The metallic layers and the polymer layers are each applied alternately, the two outer layers of polymer layers are formed.
- the layer sequence consists of a polymeric layer, followed by a metallic layer, followed by an adhesive layer, followed by a polymeric layer, followed by a metallic layer, followed by an adhesive layer, followed by a metallic layer, followed by a polymeric layer .
- the base body of the spacer 5 consists, for example, of glass fiber reinforced styrene-acrylonitrile (SAN).
- SAN glass fiber reinforced styrene-acrylonitrile
- the spacer body has a glass fiber content of 35%, for example. The glass fiber content in the spacer body improves strength and stability at the same time.
- the first glass pane 4a and the second glass pane 4b consist, for example, of soda-lime glass with a thickness of 3 mm and have dimensions of 1000 mm ⁇ 1200 mm, for example. It goes without saying that each insulating glazing unit 1 shown in this and the following exemplary embodiments can also have three or more panes of glass.
- the insulating glazing unit 1 according to Figures 1A and 1B is provided with an RFID transponder 9, for example, which is attached to the outer surface 6.1 of the sealing element 6.
- FIG. 1C shows a schematic plan view of the edge area of the insulating glazing unit 1 from FIG. 1A in a viewing direction that is identified by the arrow B in FIG. 1A.
- the operating frequency of the RFID transponder is in the UHF range and is 866.6 MHz, for example.
- the example shown is an inventive RFID transponder 9 with a slot antenna 9.1 in which the RFID electronics 9.2 are arranged in the center of the slot 9.1.1 and the base body 9.1.2 of the slot antenna 9.1 is attached to the adjacent areas and is electrically conductively connected to them, for example by two galvanic connections on both sides of the slot 9.1.1 (once at the top and once at the bottom in FIG. 1C).
- the RFID electronics 9.2 can also be arranged at a different location can be and can be connected to the slot antenna 9.1 via lines, galvanic connections or electromagnetic coupling.
- FIG. 1D shows a perspective representation of the slot antenna 9.1 according to the invention.
- This consists of a metallic base body 9.1.2, for example a rectangular copper foil with a length LG of 140 mm, a width BG of 10 mm and a thickness DG of 0.1 mm.
- the base body 9.1.2 has, for example, a slot 9.1.1 in the middle in the form of a complete recess with a length LS of 120 mm and a width BS of 2 mm.
- the edge area of the base body 9.1.2 around the slot 9.1.1 is therefore approximately 10 mm each in the longitudinal direction (LR) and approximately 4 mm each in the transverse direction (BR).
- LR longitudinal direction
- BR transverse direction
- strips 10.1, 10.2 are of the same width and length.
- the base body 9.1.2 can also consist of a comparatively rigid, thin metal plate or of a very thin metal foil or metallization, which is arranged on a carrier element, preferably a dielectric carrier element such as a polymer plate or polymer film.
- the slot antenna 9.1 is at a distance A from the outer surface of the spacer 5 5.4.
- the spacer 5 has a metalized and therefore electrically conductive (heat) insulating film 11 . Without the distance A and the dielectric sealing element 6, the slot antenna 9.1 would be arranged directly on the electrically conductive insulating film 11 and would be “short-circuited” as a result.
- the entire slot antenna 9.1 of the RFID transponder 9 can also be arranged directly on the spacer 5.
- Figure 2A shows a detailed view (cross-sectional view) of an edge area of a glazing 2 with an alternative insulating glazing unit 1 according to the invention.
- the insulating glazing unit 1 of Figure 2A essentially corresponds to the insulating glazing unit 1 or the slot antenna 9.1 according to the invention according to Figures 1A, 1B, 1C and 1 D, so that only the differences will be discussed below.
- the RFID transponder 9 together with the slot antenna 9.1 is inside the outer area 13 and essentially between the spacer 5 and the sealing element 6, between the glass pane 4b and the sealing element 6 and partly inside the sealing element 6 arranged.
- the slot 9.1.1 of the slot antenna 9.1 is offset here, for example, by 2 mm from the center of the width BG of the base body 9.1.2.
- the wider strip 10.1 of the base body 9.1.2 is arranged directly on the spacer 5.
- the wider strip 10.1 of the base body 9.1.2 is coupled to the metal or the metallization between its edge and the slot 9.1.1, so that this functionally and high-frequency-technically forms part of the Slot antenna 9.1 forms.
- the slot 9.1.1 and the narrower strip 10.2 between the slot 9.1.1 and the edge of the base body 9.1.2 are angled by about 90°, for example, and are arranged on the inner surface 19 of the glass pane 4b in the outer area 13.
- the frame 3 therefore surrounds the end face 14 of the insulating glazing unit 1 in a U-shape.
- the sections of the first and second frame elements running parallel to the large surfaces of the glass panes 4a, 4b are designed in such a way that they connect at least the outer area 13 with the sealing element 6 and the spacer frame 5' completely covered by the insulating glazing unit 1 in the viewing direction (arrow A).
- the insulating glazing unit 1 is arranged on supports, not shown here, in particular on plastic supports. Furthermore, an elastomer profile 7 is arranged between the metallic frame elements 3.1, 3.2 and the glass panes 4a, 4b, so that the insulating glazing unit 1 is held firmly within the frame 3.
- the elastomer profile 7 has a thickness of 6.5 mm, for example, and fixes the distance between the respective frame elements 3.1, 3.2 and the glass panes 4a, 4b.
- the slot 9.1.1 of the slot antenna 9.1 runs with its extension direction (i.e. its longitudinal direction (length LS)/longest dimension) parallel to the extension direction of the immediately adjacent spacer 5 or the metal frame element 3.2.
- the E field emitted by the slot antenna 9.1 runs orthogonally to the direction of extension of the slot antenna 9.1 and thus also orthogonally to the direction of extension (longest dimension) of the spacer 5 or the frame 3.2. Since the spacer 5 and the frame 3.2 are very narrow in the direction parallel to the E field (approx. 10 mm - 40 mm), the E field is only very weakly damped. This leads to a high radiation power or sensitivity for sent or received signals in the wavelength range of the RFID operating frequency. With an RFID reader, signals could be read at relatively large intervals and sent to the RFID transponder 9 .
- FIG. 2B shows a detailed view (cross-sectional representation) of an edge area of an alternative glazing 2 with an insulating glazing unit 1 according to a further embodiment of the invention.
- Figure 2B shows a modified construction, which largely includes the elements and the structure of the glazing 2 Insulating glazing unit 1 according to Figures 2A. In this respect, the same reference numbers are used as there and the structure is not described again here.
- the insulating glazing units 1 of FIGS. 2A and 2B differ in the shape of the slot antenna 9.1.
- the base body 9.1.2 is made wider and is guided up to the end face 14 of the glass pane 4b and glued to it, for example.
- the slot 9.1.1 can again be arranged centrally with respect to the width BG of the base body 9.1.2.
- FIG. 3 shows a detailed view (cross-sectional representation) of an edge area of an alternative glazing 2 with an insulating glazing unit 1 according to a further embodiment of the invention.
- FIG. 3 shows a modified construction which largely has the elements and the structure of the glazing 2 with the insulating glazing unit 1 according to FIG. 2B. In this respect, the same reference numbers are used as there and the structure is not described again here.
- the insulating glazing units 1 of FIG. 3 and FIG. 2B differ essentially in the position at which the slot antenna 9.1 is arranged on the insulating glazing unit 1.
- the RFID transponder 9 with the slotted antenna 9.1 is arranged on the outer surface 18 of the glass pane 4b and fastened, for example, by gluing.
- the top view of the RFID transponder 9 (in the direction of arrow A) is covered by the frame 3 . Due to the distance between the slot antenna 9.1 and the metallic frame element 3.2 by the elastomer profile 7, a high-frequency technical short circuit of the slot antenna 9.1 is avoided by the frame element 3.2.
- FIG. 4A shows a perspective representation of an alternative embodiment of a slot antenna 9.1 according to the invention. In terms of shape, dimensions and material, this essentially corresponds to slot antenna 9.1 from FIG. 1D, so that only the differences will be discussed below.
- the RFID electronics 9.2 are galvanically connected to the slot antenna 9.1 in the case of the slot antenna 9.1 from FIG. 1D, the RFID electronics 9.2 in FIG. 4A are electromagnetically coupled to the slot antenna 9.1.
- the RFID electronics 9.2 are galvanically connected to a coupling antenna 9.3, which is ring-shaped, for example.
- the coupling antenna 9.3 is separated from the base body 9.1.2 of the slot antenna 9.1 by a distance d of, for example, 0.3 mm, for example by means of a polymer intermediate layer (not shown), such as a plastic film, and is galvanically isolated.
- the coupling antenna 9.3 is able to stimulate an electromagnetic signal in the slot antenna 9.1 or to receive it from the slot antenna 9.1 and forward it to the RFID electronics 9.2.
- FIG. 4B shows a perspective illustration of a further development of slot antenna 9.1 from FIG. 4A, so that only the differences from FIG. 4A will be discussed below.
- the coupling antenna 9.3 is not arranged in the middle of the slot 9.1.1 with respect to the longitudinal direction, but rather in an end area (here at the left end). Furthermore, the slot
