[0006] Insulating element
[0007] - 10
[0008] The invention relates to an insulating element, preferably separately manageable, and in particular transparent or translucent, preferably an insulating glass unit, in particular a multiple-pane insulating glass unit, which is formed from several components comprising several individual plates, in particular individual glass panes, arranged essentially parallel to each other 15, which are held at a distance from each other by means of at least one spacer, preferably running around, within the boundary of a chamber, and which has at least one edge profile 20 connecting the individual plates and running around the outer edges of the individual plates, by means of which the chamber, preferably filled with a gas or gas mixture, is sealed, for example hermetically.
[0009] Technological background and state of the art
[0010] 25 Prior art multiple-pane insulating glass typically consists of two or more panes of glass, in particular float glass, but can also consist of rolled glass or other flat or plate-shaped glass or glass substitute products. Prior art multiple-pane insulating glass represents a unit hermetically sealed at the edge by means of a sealant, 30 which consists of at least two panes of glass separated from each other by one or more spacers, and is mechanically stable and durable. The edge seal of prior art multiple-pane insulating glass serves to limit the diffusion of water vapor and gases between the interior of the multiple-pane insulating glass, also referred to as a chamber, cavity, or space, and the outside atmosphere. The edge seal exhibits a certain degree of physical and chemical resistance.The sealant consists of a polymer material which, depending on the application, exhibits mechanical and physical properties with regard to cohesion and adhesion to glass and / or spacers that are sufficient for the edge seal. State-of-the-art multi-pane insulating glass is also referred to as insulating glass units.
[0011] Modern multi-pane insulating glass has several disadvantages. For example, the edge seal of such a multi-pane insulating glass unit cannot be separated into its individual components, or only with great difficulty. This is due to a statically effective, preferably polymeric, seal, particularly a secondary seal, for example made of polyurethane, by means of which the panes are so firmly bonded or chemically connected at their outer edges that the seal or secondary seal must be destroyed to separate the panes, leaving residues of the seal or secondary seal adhering to the panes. Consequently, multi-pane insulating glass is either not recyclable or only very limitedly recyclable at the end of its service life.On the other hand, according to the state of the art, the edge seal does not allow for economical repair of the glass panes in the event of failure of only one component of the insulating glass unit or the multiple-pane insulating glass unit, for example in the case of glass breakage.
[0012] From DE 1 434 175 A and DE 1 434 175 C of the applicant, an insulating glass unit and a multi-pane insulating glass unit, respectively, are known. The transparent insulating glass unit and the multi-pane insulating glass unit have a cavity filled with at least one dry gas, which is formed by two transparent panes resting at a distance on a closed frame formed from four metal tubes. The inner surfaces of the panes have wedge-shaped grooves in the frame for receiving a sealing adhesive. The transparent panes rest against the metal tubes along lines of contact. The metal tubes thus act as spacers, keeping the panes apart. The spacer limits the space between the panes, also referred to as the cavity. The panes are clamped in an outer frame made of wood, metal, or the like, which is attached on-site, and are pressed firmly against the frame formed from the metal tubes.The multi-pane insulating glass unit is thus inserted into the outer frame, which is attached on-site. According to the applicant's supplementary patents DE 1 509 170 A and DE 1 509 170 C, the metal tubes can essentially have a U-shaped cross-section, and the flat outer surface of each metal tube is located on the inside and perpendicular to the panes. According to these four patents, dowel-like inserts can be inserted into the ends of the metal tubes, to which the metal tubes are attached by means of screws. The frame formed by the metal tubes creates wedge-shaped grooves with the inner surfaces of the panes. After the panes are pressed against the frame with a clamping device, the wedge-shaped grooves formed in the outer edge area are filled with a sealant, so that the sealant and the end faces of the panes form a smooth end face of the multi-pane insulating glass unit. After completion, the clamping device is removed.
[0013] A method for manufacturing a highly insulating element is known from WO 2017 / 063006 A2. In this method, hermetically sealed pre-chambers and a main chamber are formed by plates arranged largely parallel to each other and a sealing edge bond. Each of the resulting chambers has a supply pipe and an evacuation pipe. In a first step of the manufacturing process, a filling medium is introduced via each supply pipe, displacing the ambient air in the chambers through the evacuation pipes. In a second step, the supply pipes are sealed gas-tight, and in a third step, the filling medium is evacuated from the chambers through the evacuation pipes.Each chamber is sealed gas-tight by means of three seals, with a primary seal made of polyisobutylene (synthetic rubber) in an inner first sealing zone, a secondary seal, for example made of silicone or polysulfide, in a second sealing zone following to the outside, and a tertiary seal, which is a physical spring made of a sealant with an adapted modulus of elasticity, in a third sealing zone following to the outside.
[0014] DE 200 08 654 U1 discloses an insulating glass unit with individual panes and a spacer profile. The spacer profile serves to keep the individual panes of a multi-pane insulating glass unit at a distance, thereby sealing and keeping dry the space between the panes. The spacer profile has an internal cavity for holding a desiccant. A sealant or gasket is applied to its side surfaces facing the panes in their service position. The spacer profile can also extend through the corners of the panes and be curved.
[0015] From DE 3050405 C1 and from the parallel EP 0054251 A1, a spacer profile for multiple-pane insulating glass has become known.
[0016] From EP 1 002 925 A2 a method for assembling and pressing insulating glass with a first glass pane and a second glass pane and a spacer made of thermoplastic material arranged between them is known, in which the spacer is injected onto the first glass pane.
[0017] From DE 10 2020 130 491 A1 and the parallel WO 2022 / 106069 A1, a multi-pane insulating glass unit and a method for manufacturing it are each known. The multi-pane insulating glass unit comprises at least two panes with an edge seal between them. The edge seal has a circumferential spacer and separates an interpane cavity from an outer cavity. A primary sealant is provided between the circumferential spacer and the panes, sealing the interpane cavity from the outer cavity. According to the invention, an elastic seal is provided there, which, viewed from the interpane cavity, is arranged in front of the primary sealant and provides a seal between the spacer and a pane.
[0018] From WO 2011 / 088484 A1 a spacer for insulating glass has become known, which is a spacer strip consisting of a carrier strip and a compressible, in particular foldable, tube.
[0019] Summary of the invention
[0020] The invention is based on the objective of providing an insulating element that can be manufactured simply and cost-effectively from individual components and that can be easily disassembled into individual components in a non-destructive manner and essentially without residue, so that these components are replaceable during the service life of the insulating element and are also almost completely or one hundred percent recyclable or reusable at the end of the service life of the insulating element.
[0021] This problem is solved by the features of claim 1. Accordingly, the invention relates to an insulating element, preferably separately handleable, and in particular transparent or translucent, preferably an insulating glass unit, in particular a multiple-pane insulating glass unit, which is formed from several components comprising several essentially parallel individual panes, in particular individual glass panes, which are held at a distance from each other by means of at least one spacer, preferably a circumferential spacer, within the boundary of a chamber, which may also be called an interior space or an intermediate space, and which has at least one edge profile connecting the individual panes and circumferentially surrounding the outer edges of the individual panes, by means of which the chamber, preferably filled with a gas or gas mixture, is sealed, for example, hermetically.According to the invention, the at least one edge profile running around the outer edges of the individual plates comprises several releasable, separate, manageable, rigid or spring-elastic individual profile parts or individual edge profile parts, which frame around the outer edges of the individual plates or which form a frame encompassing the outer edges of the individual plates, preferably square or rectangular, and which can be removed from the individual plates either substantially without residue or completely without residue, and which are releasably clamped together by means of at least one clamping device, and / or which are designed as clamping means or with clamping means that are releasably clamped to the individual plates, preferably to the outer surfaces of the individual plates, in the area of the outer edges of the individual plates.so that each individual profile part or individual edge profile part of the individual profile parts or of the individual edge profile parts directly or indirectly exerts a compressive force on the individual plates in the area of their individual plate outer edges, which causes, for example, a hermetic seal of the chamber.
[0022] This makes it possible to manufacture the insulating element particularly easily and cost-effectively from individual components and to disassemble it into its individual components in a simple, non-destructive and essentially residue-free manner, so that these components are replaceable during the service life of the insulating element and are also almost completely or one hundred percent recyclable or reusable at the end of the insulating element's service life.
[0023] The invention relates in particular to the design of an edge seal for an insulating element, preferably an insulating glass unit or a multi-pane insulating glass unit, which is typically, but not exclusively, used in the building envelope of a building. The main areas of application of the invention relate to insulating elements, in particular insulating glass units or multi-pane insulating glass units, for installation in windows, doors, curtain walls, bonded glazing for doors, windows, curtain walls, roofs, and partition walls.
[0024] The invention preferably relates to a novel edge seal which, particularly due to its absence of a statically effective, preferably polymeric, non-removable seal or secondary seal, allows for easy separation into the individual components of the insulating glass unit or the multiple-pane insulating glass unit (glass panes and edge seal materials or frame construction). The virtually adhesive-free edge seal enables a sustainable circular economy for the components and materials used.
[0025] The invention differs from the prior art in particular in that the edge seal of the insulating element, especially of the insulating glass unit or the multiple-pane insulating glass unit, is almost completely or completely recyclable.
[0026] In the insulating element according to the invention, the use of adhesives and sealants is reduced by at least 50%, and in particular by up to 90%, compared to multi-pane insulating glass or multi-pane insulating glazing according to the prior art. This is achieved by eliminating a polymeric seal, especially a secondary seal, which cannot be removed without leaving residue. However, the insulating element according to the invention can have a primary seal, preferably polymeric, in particular made of polyisobutylene (in practice also referred to simply as "butyl"). This primary seal can serve to seal the chamber or the space between the plates or panes and the edge profile surrounding the outer edges of the individual plates or panes against the outside.
[0027] The insulating element according to the invention can be easily disassembled into its individual components (plates, discs, or glass panes and edge seal). This means that the materials used can be separated from one another without mechanical or chemical intervention. This allows for easy replacement of individual components during use or virtually residue-free disassembly after the product has been used. Disassembly is thus guaranteed both during use and at the end of its service life (sustainability – circularity or circular economy).
[0028] Preferably, the chamber or the space between the panes is dehumidified by suitable measures, for example, using a desiccant, in order to reduce the risk of condensation on the plate or glass surfaces in the chamber or space between the panes and thus prevent possible clouding ("blinding") of the insulating element as far as possible. Conditioning of the chamber or space is based on a sophisticated ventilation technology that utilizes mechanical, physical, and / or chemical principles. According to a preferred embodiment, a replaceable dehumidifier cartridge can be provided for dehumidification or conditioning. The dehumidifier cartridge can contain a desiccant.
[0029] The individual panels of the insulating element or the individual panes of the insulating glass unit or the multiple-pane insulating glazing can, preferably on one side, be coated with low-emissivity coatings that improve the thermal insulation properties by reducing heat loss through radiation. A surface treatment to reduce visible condensation can also be provided. Depending on the embodiment and / or application, it may be accepted that the design of the edge seal according to the invention does not constitute or effect a hermetic seal of the space between the panes or the chamber.
[0030] In contrast to insulating glass units or multi-pane insulating glass units according to the prior art, the insulating element according to the invention does not have a load-bearing, bonded, non-removable polymeric seal, in particular a secondary seal, which allows for simple and essentially residue-free separation into its individual components. The design of the edge seal of the insulating element according to the invention ensures durability without the use of such a seal or secondary seal.
[0031] The functions of a non-removable seal or secondary seal according to the prior art are fulfilled by other components due to the design, with regard to sealing the insulating element and absorbing tensile forces. Forces, particularly compressive forces, caused by the frame construction or the type of connection between the individual profile parts that frame around the outer edges of the individual panels, or between the individual profile parts that encircle the outer edges of the individual panels as a frame (preferably closed), and which act both in the plane of the panels or slabs and perpendicular to them, contribute to sealing the edge seal.
[0032] According to a preferred first embodiment, the clamping device may comprise at least one flexible or bendable clamping element, in particular at least one clamping band or at least one clamping strap, which is subjected to tensile stress in the tensioned state. This enables particularly simple and effective clamping of the individual profile sections or the individual edge profile sections and simple and cost-effective manufacturing of the insulating element.
[0033] It can be provided that the at least one flexible or bendable clamping element clamps at least two, at least three, at least four, or all of the individual profile parts together. Clamping several or all of the individual profile parts, or all of the individual edge profile parts, using the at least one clamping element enables particularly simple and cost-effective assembly and disassembly of the insulating element.
[0034] According to one embodiment, each individual profile part, or each individual edge profile part, is provided with a concave curvature, preferably acting as a raised section, or with a material accumulation or support, preferably acting as a raised section, on the outer edge of the individual plates, viewed from the chamber or the space between them and from the respective associated outer edge of the individual plates. The at least one flexible or bendable clamping element bears against this material under compressive force. This ensures a particularly effective seal of the chamber or the space between the plates or discs to the outside.
[0035] According to a preferred embodiment, the clamping device may comprise at least one clamping element, preferably manually operated, or a clamping device, preferably manually operated, for clamping the at least one flexible or bendable clamping element. This enables even simpler and more effective clamping of the individual profile sections or the individual edge profile sections, and a further comparatively simple and cost-effective manufacture of the insulating element. Alternatively, the at least one flexible or bendable clamping element may have a first clamping element end and a second clamping element end, which are preferably directly, for example by welding, firmly connected to one another. A clamping device or a clamping machine may be used to clamp the flexible or bendable clamping element, which, after clamping and firmly connecting, or...The welding of the first and second ends of the clamping element can be removed.
[0036] According to a second embodiment, the clamping device can be designed as a clamping fastener, preferably manually operated, for example an eccentric clamping fastener or toggle clamping fastener, for directly clamping a first individual profile part of the individual profile parts or a first individual edge profile part of the individual edge profile parts with an immediately adjacent second individual profile part of the individual profile parts or second individual edge profile part of the individual edge profile parts, which comprises a first clamping fastener part attached to the first individual profile part or first individual edge profile part and a second clamping fastener part attached to the second individual profile part or second individual edge profile part. This also allows for particularly simple and effective clamping of the individual profile parts.the single edge profile parts and a simple and cost-effective production of the insulating element is made possible.
[0037] According to an alternative embodiment, each spring-elastic individual profile part, or each individual edge profile part, is pre-formed with a concave curve towards the outer edge of the respective individual plate. This also ensures a particularly effective seal of the chamber or the space between the plates or discs to the outside. According to a particularly preferred embodiment, the individual profile parts or the individual edge profile parts are each formed in one piece with at least one spacer, by means of which the individual plates are held at the specified distance from each other, defining the boundaries of the chamber. Preferably, the individual profile parts and their respective spacers can each be manufactured from a single piece.These measures enable a particularly simple and cost-effective construction with further improved sealing of the chamber or the space between the plates or panes to the outside.
[0038] According to a particularly preferred embodiment, the individual profile parts or the individual edge profile parts can each be provided with recesses for receiving the individual plates, wherein at least one individual plate is received in each recess, with its corresponding outer edge, and wherein at least one spacer is formed between a first recess and an immediately adjacent second recess. The recesses can be grooves arranged at a spacing corresponding to the individual plate spacing. These measures enable a particularly simple and stable construction with further improved sealing properties.
[0039] According to a further development, the at least one edge profile circumferentially surrounding the outer edges of the individual plates may comprise at least one, in particular circumferential, primary seal for sealing the chamber. This primary seal is arranged between each individual profile part and each outer edge of an individual plate, and is removable from the individual plates and profile parts essentially without residue or completely without residue. This allows the inventive problem to be solved to a particularly high degree, while additionally achieving a further improved seal of the chamber or the space between the plates or discs to the outside.
[0040] It is particularly advantageous if each individual profile part of the individual profile parts, or each individual edge profile part of the individual edge profile parts, exerts a compressive force directly or indirectly on the individual plates in the area of their outer edges via the at least one primary seal, resulting in a seal of the chamber, preferably hermetic. This enables a further improvement in line with the aforementioned advantages.
[0041] According to one embodiment, the at least one edge profile surrounding the outer edges of the individual plates comprises at least one further seal, preferably a circumferential one, for sealing the chamber. This further seal is a metal seal, preferably made of aluminum foil or sheet steel, which is arranged between each individual profile part and the at least one primary seal and which can be removed from the individual plates and from the individual profile parts or individual edge profile parts essentially without residue or completely without residue. This allows the inventive problem to be solved to a particularly high degree, while additionally achieving a further improved seal of the chamber or the space between the plates or discs to the outside.
[0042] It is particularly advantageous to provide that each individual profile part of the individual profile parts, or each individual edge profile part of the individual edge profile parts, exerts a pressure force directly or indirectly on the individual plates in the area of their outer edges via at least one further seal, thus creating a, preferably hermetic, seal of the chamber. This enables a further improvement in line with the aforementioned advantages. According to a preferred embodiment, it can be provided that at least one primary seal and / or at least one further seal are arranged or formed in each recess of the individual profile parts or the individual edge profile parts. These measures enable further improved sealing conditions through a particularly simple design.
[0043] According to an alternative embodiment, the spring-elastic individual profile parts or individual edge profile parts, designed as or with the clamping means, can be made of metal, preferably spring steel. This makes assembly and disassembly of the insulating element particularly easy.
[0044] According to a preferred embodiment, the spring-elastic individual profile parts or individual edge profile parts can be designed, pre-formed, or pre-stressed in such a way that they can only be clamped to the respective, diverging outer surfaces of the individual plates by exerting a spring-elastic deformation or only after a spring-elastic deformation, preferably by spring-elastic restoring forces, and in particular can be attached or slid onto the respective outer edge of the individual plates. This further simplifies and improves the assembly and disassembly of the insulating element.
[0045] According to a further development, it can be provided that the spring-elastic individual profile parts or individual edge profile parts are designed or can be equipped with lateral actuating elements, in particular lateral actuating legs, so that, preferably similar to so-called "binder clips" used in office environments for the releasable binding of paper pages, etc., they can be clamped to the respective outer edges of the individual plates after the actuating elements are pressed together, preferably by spring-elastic restoring forces, and in particular can be attached or slid onto the respective outer edge of the individual plates. This enables a further improvement in line with the aforementioned advantages.
[0046] It goes without saying that the aforementioned measures can be combined with each other as desired, within the limits of feasibility.

[0067] In the first embodiment of the invention relating to the insulating element 20.1, the individual profile parts 30.1.1, 30.1.2, 30.1.3, 30.1.4 are releasably clamped together by means of at least one clamping device 35 such that each individual profile part 30.1.1, 30.1.2, 30.1.3, 30.1.4 exerts a compressive force 33.1.1, 33.1.2 on the individual plates 22.1, 22.2 in the area of their individual plate outer edges 26, which causes a seal of the chamber 24.1. The clamping device 35 comprises at least one flexible or bendable clamping element 36 in the form of a clamping band or strap, which is subjected to tensile stress in the tensioned state (see the tensile force arrows 37 in Figure 1). All individual profile parts 30.1.1, 30.1.2, 30.1.3, 30.1.4 are releasably clamped together by means of the clamping band or strap 36.The tensioning device 35 comprises a tensioning device 38, preferably manually operable, for tensioning the flexible or bendable tensioning band or tensioning strap 36, preferably manually.
[0068] The primary seal 32.1.1, 32.1.2 is arranged between a single profile part 30.1.1, 30.1.2, 30.1.3, 30.1.4 of the single profile parts 30.1.1, 30.1.2, 30.1.3, 30.1.4 and a single plate outer edge 26 of the single plate outer edges 26 of the respective single plates 22.1, 22.2 immediately adjacent to the respective single plate outer edge 26.
[0069] The at least one circumferential edge profile 27.1, which surrounds the outer edges 26 of the individual plates, optionally comprises at least one further, in particular circumferential, seal 39 for sealing the chamber 24.1. This further seal 39 is a metal seal. Preferably, it is an aluminum foil or a sheet of steel. A gas-tight seal of the chamber 24.1 can be achieved by means of the further seal 39. The or each further seal 39 is arranged at least partially between one or each of the individual profile parts 30.1.1, 30.1.2, 30.1.3, 30.1.4 and the at least one primary seal 31.1, 31.2. Each additional seal 39 can be completely removed without leaving any residue from the individual plates 22.1, 22.2 and from the individual profile parts 30.1.1, 30.1.2, 30.1.3, 30.1.4 or individual edge profile parts. Each individual profile part 30.1.1, 30.1.2, 30.1.3, 30.1.4 of the individual profile parts 30.1.1, 30.1.2, 30.1.3, 30.1.4 or each individual edge profile part of the individual edge profile parts also exerts a pressure force 33.1.1, 33.1.2 directly or indirectly on the individual plates 22.1, 22.2 in the area of their individual plate outer edges 26 via the at least one further seal 39, which causes a, preferably hermetic, seal of the chamber 24.1.
[0070] In the first embodiment shown, in each recess 31.1.1, 31.1.2 of the recesses 3.1.1, 31.1.2 of the individual profile parts 30.1.1, 30.1.2, 30.1.3, 30.1.4 or of the individual edge profile parts, both the at least one primary seal 32.1.1, 32.1.2 and the at least one further seal 39 are arranged or formed. The additional seal 39 is inserted into the recesses 31.1.1, 31.1.2 such that it is at least partially arranged between the respective primary seal 32.1.1, 32.1.2 and an associated recess base 28.1, 28.2 of the respective recess 31.1.1, 31.1.2 or groove base of the groove of the respective individual profile part 30.1.1, 30.1.2, 30.1.3, 30.1.4. Furthermore, the at least one additional seal 39 is inserted into both recesses 3.1.1, 31.1.2, preferably such that it overlaps or engages behind the respective spacer 23.1, so that the respective additional seal 39 delimits the chamber 24.1.
[0071] In contrast to the first embodiment of the invention shown in Figures 1 to 5, in the second embodiment of the invention shown in Figures 6 to 10, the individual profile parts 30.2.1, 30.2.2, 30.2.3, 30.2.4 of the insulating element 20.2 are each designed as a clamping means 40 or with a clamping means or as a clamping body or with clamping bodies, which are releasably clamped to the individual plates 22.1, 22.2 in the region of the outer edges 26 of the individual plates, preferably on the outwardly facing outer surfaces 29.1, 29.2 of the individual plates 22.1, 22.2, such that each individual profile part 30.2.1, 30.2.2, 30.2.3, 30.2.4 of the Individual profile parts 30.2.1, 30.2.2, 30.2.3, 30.2.4 exert a compressive force 33.2.1, 33.2.2 on the individual plates 22.1, 22.2 in the area of their individual plate outer edges 26, which causes a sealing of the chamber 24.2.
[0072] The individual profile parts 30.2.1, 30.2.2, 30.2.3, 30.2.4 are designed to be spring-elastic. They are preferably made of spring steel. The spring-elastic individual profile parts 30.2.1, 30.2.2, 30.2.3, 30.2.4, or individual edge profile parts, are designed, pre-formed, or pre-stressed such that they can only be clamped to the respective associated individual plate outer surfaces 29.1, 29.2 of the associated individual plates 22.1, 22.2 by spring-elastic restoring forces after or by exerting a spring-elastic deformation. The spring-elastic individual profile parts 30.2.1, 30.2.2, 30.2.3, 30.2.4, or individual edge profile parts, are designed, pre-formed, or pre-stressed such that they can only be clamped to the respective associated individual plate outer surfaces 29.1, 29.2 by spring-elastic restoring forces after a spring-elastic deformation.

The individual profile part 30.2.1, or each individual profile part 30.2.1, 30.2.2, 30.2.3, 30.2.4, has a spring-elastic base leg 41 and two spring-elastic clamping legs 42.1, 42.2 extending from it in approximately the same direction for clamping the individual profile part 30.2.1, or the respective individual profile part 30.2.1, 30.2.2, 30.2.3, 30.2.4 to the associated individual plate outer surfaces 29.1, 29.2 of the individual plates 22.1, 22.2 or the individual glass panes. The individual profile part 30.2.1, 30.2.2, 30.2.4, or each individual profile part 30.2.1, 30.2.2, 30.2.4, is made of spring steel.3, 30.2.4 is prestressed in the unloaded state such that the free ends 43.1, 43.2 of its two spring-elastic clamping legs 42.1, 42.2 have a leg distance 44 to each other which is smaller than a transverse distance 45 that the outwardly facing individual plate outer surfaces 29.1, 29.2 of the individual plates 22.1, 22.2 or individual discs have to each other in the fully assembled state of the insulating element 20.2 (see Figures 10 and 11). Preferably, each separate spring-elastic individual profile part 30.2.1, 30.2.2, 30.2.3, 30.2.4 is designed symmetrically to a longitudinal plane 46 in the unloaded state, which contains a longitudinal axis 47 of the individual profile part 30.2.1, 30.2.2, 30.2.3, 30.2.4 (see Figure 11).
[0074] In the fully assembled insulating element 20.2 according to the second embodiment, the spring-elastic individual profile parts 30.2.1, 30.2.2, 30.2.3, 30.2.4 or individual edge profile parts are attached or pushed onto the respective associated individual plate outer edge 26 of the individual plates 22.1, 22.2 and clamped by means of the respective two clamping legs 42.1, 42.2 to the respective individual plate outer surfaces 29.1, 29.2 of the associated individual plates 22.1, 22.2 by spring-elastic restoring forces (see Figure 10).
