Abstract

The glazing element is provided with at least one tensioned insulation form (2) between two panes (1). Spring elements (3) secured to a tension profile (4) serve to place the film under tension. The spring elements are distributed over the entire film periphery. They are also elastically bendable in all directions transverse to their elongation, and are secured with their longitudinal direction essentially perpendicular to the film plane with one end at the film and the other end secured to the tension profile In this manner, the spring elements can elastically follow relative shape alterations of the film with respect to the tension profile by bending transversely to their longitudinal direction. In this novel construction, tension forces are distributed in all directions in the insulation film. No friction forces need to be overcome in order to tension the film. The entire tension taken up by the film support is so small that it is possible simply to adhere the tension profile inwardly to the panes. Simple helical coils can be used as the spring elements

Description

Die vorliegende Erfindung betrifft ein Verglasungselement mit mindestens einer zwischen zwei Scheiben ausgespannten Isolationsfolie, wobei zum Spannen der Folie von einem Spannprofil gehaltene Federelemente verwendet sind, die zwischen zwei Enden eine Längserstreckung aufweisen.The present invention relates to a glazing element with at least one insulating film stretched between two panes, spring elements held by a clamping profile being used for stretching the film and having a longitudinal extension between two ends.

Ein Verglasungselement dieser Art ist beispielsweise bekannt aus dem BE-A-867627. Bei dem bekannten Element ist eine Folie im unteren Teil des Elements um einen Balken geschlungen. Ihre beiden freien Endkanten sind im oberen Teil des Elements mit Abstand parallel zueinander im Element-Rahmen fest eingespannt. Die beiden Folienhälften werden durch als Schraubendruckfedern ausgebildete Federelemente unter Spannung gehalten. Diese stützen sich einerseits innenseitig gegen ein rechteckiges Spannprofil und andererseits gegen Köpfe von Schrauben ab, die einerseits durch die Folie in den Balken eingeschraubt sind und andererseits in das Spannprofil hineinragen. Die genannten Schrauben durchsetzen die Druckfedern zentral. Die Längserstreckung bzw. Achsrichtung der Federn entspricht der Richtung der Zugspannung auf die Folie. Durch die bekannte Konstruktion können allenfalls temperaturbedingte Längenänderungen der Folien bzw. Folienhälften ausgeglichen werden. Gleichzeitig auftretende Breitenänderungen können nicht kompensiert werden, ebensowenig wie eine ungleiche Änderung beider Folien.A glazing element of this type is known, for example, from BE-A-867627. In the known element, a film is in the lower part of the element around a bar looped. Their two free end edges are firmly clamped in the element frame at a distance parallel to each other in the upper part of the element. The two film halves are held under tension by spring elements designed as helical compression springs. These are supported on the inside against a rectangular clamping profile and on the other hand against heads of screws which are screwed through the film into the beam and protrude into the clamping profile. The screws mentioned penetrate the compression springs centrally. The longitudinal extension or axial direction of the springs corresponds to the direction of the tensile stress on the film. The known construction can at best compensate for temperature-related changes in length of the films or film halves. Changes in width that occur simultaneously cannot be compensated for, just as little as an unequal change in both foils.

In dem CH-A-653404 wird ein selbsttragendes Isolationselement mit einer Isolationsfolie zum Einsetzen zwischen die Scheiben eines Verbundfensters beschrieben, bei dem einer Längen- und Breitenänderung der Folie Rechnung getragen wird. Die Folie ist hier auf einen rechteckigen Spannrahmen relativ zu diesem beweglich biaxial ausgespannt. Die Seitenteile des Spannrahmens sind entsprechend der gewünschten Folienspannung im unbelasteten Zustand einseitig vorgebogen. Die Beweglichkeit der Folie gegenüber dem Spannrahmen ergibt sich durch eine diskontinuierliche Befestigung der Folie auf vier Gleitbändern, die in Längsrichtung der Rahmenseiten dehnbar und längs dieser verschiebbar geführt sind. Durch die Reibung zwischen den Gleitbändern und ihren Führungen am Spannrahmen erhöht sich bei dieser Konstruktion allerdings die vom Spannrahmen aufzunehmende gesamte Spannung. Zum Spannen und Straffhalten der Folie muss diese Reibung nämlich stets überwunden werden. Damit die von der Folienspannung herrührenden Reaktionskräfte sich nicht auf den durch Kleben hergestellten und Dichtzwecken dienenden Randverbund zwischen dem Spannrahmen und den beiden Scheiben auswirken kann, ist der Spannrahmen freitragend ausgebildet.CH-A-653404 describes a self-supporting insulation element with an insulation film for insertion between the panes of a composite window, in which a change in length and width of the film is taken into account. The film is stretched biaxially movable on a rectangular tenter frame relative to this. The side parts of the tenter frame are pre-bent on one side in accordance with the desired film tension in the unloaded state. The mobility of the film in relation to the stenter results from a discontinuous fastening of the film on four sliding bands, which are stretchable in the longitudinal direction of the frame sides and slidable along these. Due to the friction between the sliding bands and their guides on the stenter, the overall tension to be absorbed by the stenter increases with this construction. To tension and hold the film tight, this friction must always be overcome. So that the reaction forces resulting from the film tension cannot affect the edge bond between the stenter and the two panes, which is produced by gluing and serves sealing purposes, the stenter is designed to be self-supporting.

Aufgabe der Erfindung ist, ein Verglasungselement der eingangs genannten Art anzugeben, bei dem die Faltenfreiheit der Isolationsfolie bei allen Arten von Formveränderungen, insbesondere infolge von Wärmedehnungen, selbst unterschiedlichen von Folie und Rahmen, in einem weiten Temperaturbereich von mindestens -40°C bis +60°C erhalten bleibt und das einfacher in seiner Konstruktion sowie mit weniger Material und geringerem Fertigungsaufwand herstellbar ist.The object of the invention is to provide a glazing element of the type mentioned at the outset, in which the freedom from wrinkles of the insulating film in all types of shape changes, in particular as a result of thermal expansion, even different films and frames, in a wide temperature range from at least -40 ° C. to +60 ° C is maintained and that is easier to manufacture, less material and less manufacturing effort.

Diese Aufgabe wird erfindungsgemäss gelöst durch ein Verglasungselement mit den Merkmalen des Patentanspruchs 1.According to the invention, this object is achieved by a glazing element having the features of patent claim 1.

Bei dem erfindungsgemässen Verglasungselement sind demnach die Federelemente über den gesamten Folienumfang verteilt angeordnet. Sie sind quer zu ihrer Längserstreckung allseitig elastisch biegsam und derart mit ihrer Längserstreckung im wesentlichen senkrecht zur Folienebene mit ihrem einen Ende an der Folie und mit ihrem anderen Ende am Spannprofil befestigt, dass sie relativen Formänderungen der Folie gegenüber dem Spannprofil durch Biegung quer zu ihrer Längserstreckung elastisch folgen können.In the glazing element according to the invention, the spring elements are accordingly arranged distributed over the entire circumference of the film. They are resiliently flexible on all sides transverse to their longitudinal extension and are fixed with their longitudinal extension essentially perpendicular to the film plane with one end on the film and the other end on the clamping profile in such a way that they change the shape of the film relative to the clamping profile by bending transversely to its longitudinal extension can follow elastically.

Bei der neuen Konstruktion wirken auf die Isolationsfolie allseitig verteilte Spannkräfte. Zum Spannen müssen keine Reibungskräfte überwunden werden. Die gesamte von der Folienhalterung aufzunehmende Spannung kann deshalb erheblich geringer bemessen werden als bei den bekannten Konstruktionen. Es ist nicht erforderlich, aus diesen einen freitragenden Rahmen zu bilden. Durch die Federelemente werden Fertigungstoleranzen selbsttätig weitgehend ausgeglichen. Bei einer bevorzugten Ausführungsform der Erfindung sind die Spannprofile direkt innen an den Scheiben angeklebt. Es können relativ einfache Spannprofile und als Federelemente billige Schraubenfedern verwendet werden.With the new design, clamping forces distributed on all sides act on the insulation film. No friction forces have to be overcome for clamping. The total tension to be absorbed by the film holder can therefore be dimensioned considerably less than in the known constructions. It is not necessary to form a self-supporting frame from these. Manufacturing tolerances are largely automatically compensated for by the spring elements. In a preferred embodiment of the invention, the clamping profiles are glued directly to the inside of the panes. Relatively simple clamping profiles and cheap coil springs can be used as spring elements.

Weitere Vorteile sowie Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen gekennzeichnet.Further advantages and refinements of the invention are characterized in the dependent claims.

Nachfolgend wird die Erfindung anhand eines in der beigefügten Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Die Zeichnung zeigt in einer einzigen Figur im Schnitt den unteren Teil eines erfindungsgemäss ausgebildeten Verglasungselements mit zwei gleichartig ausgespannten Isolationsfolien. Von Teilen, die auf Grund des zu seiner Mittenebene weitgehend symmetrisch aufgebauten Elements in der Figur identisch auf beiden Seiten der Mittenebene vorhanden sind, ist jeweils nur eines mit einem Bezugszeichen versehen.The invention is explained in more detail below on the basis of an exemplary embodiment shown in the accompanying drawing. The drawing shows in a single figure in section the lower part of a glazing element designed according to the invention with two similarly stretched insulation foils. Of parts that are identical on the two sides of the central plane due to the largely symmetrical element in the figure, only one is provided with a reference number.

Mit 1 sind in der Zeichnung zwei zueinander parallele flache Glasscheiben bezeichnet. Zwischen den Scheiben 1 sind ebenfalls parallel zueinander sowie parallel zu den Scheiben zwei Isolationsfolien 2 ausgespannt. Zur Halterung und zum Spannen der Folien 2 dienen unter anderem Schraubenfedern 3. Diese sind bezüglich ihrer Achsrichtung bzw. ihrer Längserstreckung zwischen ihren beiden Enden im wesentlichen senkrecht zur Ebene der Folien 2 ausgerichtet und mit ihrem einen Ende (Fussteil) in Spannprofilen 4 verankert. Mit ihrem anderen Ende (Kopfteil) sind sie jeweils an den Isolationsfolien 2 in deren Randzone befestigt. Die Spannprofile 4 weisen flache Seitenflächen 4.1 auf, mit denen sie innenseitig an den Scheiben 1 angeklebt sind. Durch ein Abstandsprofil 5 werden sie in gleichmässigem Abstand gehalten. Aussenseitig (in der Zeichnung unten) weist das Abstandsprofil 5 eine sich im wesentlichen über den Abstand zwischen den Scheiben 1 in der Breite erstreckende flache Aussenseite 5.1 auf, auf die ein Dichtungsband 6 als Dampfsperre aufgebracht ist. Am Abstandsprofil 5 ist weiter noch eine im Querschnitt etwa trapezförmige, mit einem Trockenmittel gefüllte Längskammer 5.2 ausgebildet, welche mit dem Fensterinnenraum über kleine Öffnungen 5.3 in Verbindung steht.1 in the drawing denotes two parallel flat glass panes. Two insulating foils 2 are also stretched parallel to one another and parallel to the panes between the panes 1. Coil springs 3 are used for holding and tensioning the foils 2. These are aligned with respect to their axial direction or their longitudinal extension between their two ends essentially perpendicular to the plane of the foils 2 and anchored with one end (foot part) in tensioning profiles 4. With their other end (head part) they are each fastened to the insulation foils 2 in their edge zone. The clamping profiles 4 have flat side surfaces 4.1 with which they are glued to the inside of the discs 1. They are kept at a uniform distance by a spacing profile 5. On the outside (in the drawing below), the spacing profile 5 has a flat outside 5.1, which extends essentially over the distance between the panes 1 and on which a sealing tape 6 is applied as a vapor barrier. On the spacer profile 5 there is also an approximately trapezoidal cross-section, filled with a desiccant, into the longitudinal chamber 5.2, which is connected to the window interior via small openings 5.3.

Zur Verbindung der Köpfe der Schraubenfedern 3 mit den Isolationsfolien 2 dienen Schweisskappen 3.1, die aus einem mit dem Folienmaterial verschmelzbaren Material bestehen und in die Köpfe der Schraubenfedern 3 eingesteckt sind. Auf den Schweisskappen 3.1 sind die Isolationsfolien 2 punktförmig angeschweisst. Die Windungen der Schraubenfedern 3 liegen stets zumindest teilweise aneinander an. Sie sind auf Druck daher nicht komprimierbar und geben beim Herstellen der Schweissverbindung z.B. mittels eines Ultraschall-Punktschweissautomaten nicht nach.To connect the heads of the coil springs 3 with the insulating foils 2 are welding caps 3.1, which consist of a material that can be fused with the foil material and are inserted into the heads of the coil springs 3. The insulation foils 2 are welded in a spot shape onto the welding caps 3.1. The turns of the coil springs 3 are always at least partially against each other. They are therefore not compressible under pressure and give e.g. when making the welded connection not by means of an ultrasonic spot welding machine.

Was in der geschnittenen Darstellung der Zeichnung nicht zu erkennen ist, ist die Verteilung einer Vielzahl von Schraubenfedern 3 rund um den ganzen Umfang der Isolationsfolien 2. Die Schraubenfedern 3 können entweder in gleichen Abständen oder, beim Vorhandensein von Ecken, zu diesen hin zunehmend dichter angeordnet sein. Es ergibt sich dann eine günstigere Spannungsverteilung auf den Folienflächen als bei gleichen Abständen. Ein geeigneter mittlerer Abstand der Schraubenfedern für eine Polyesterfolie von 75 Mikrometer Dicke ist etwa 5 cm.What cannot be seen in the sectional representation of the drawing is the distribution of a large number of coil springs 3 around the entire circumference of the insulating films 2. The coil springs 3 can either be at equal intervals or, in the presence of corners, be arranged increasingly closer to them. This results in a more favorable stress distribution on the film surfaces than at the same distances. A suitable average distance between the coil springs for a polyester film 75 micrometers thick is about 5 cm.

Die Länge der Schraubenfedern 3 beträgt etwa das 3-fache ihres Durchmessers.The length of the coil springs 3 is about 3 times their diameter.

In den Spannprofilen 4 sind die Schraubenfedern 3 in einer Längsnut 4.2 mit hinterschnittenen Flanken verankert. Ihre letzte Windung an ihrem Fussteil ist dazu gegenüber den übrigen Windungen etwas erweitert und greift mit dieser in die Hinterschneidungen der Längsnut 4.2 ein. Durch diese Art der Befestigung ist das Fussteilende der Schraubenfedern 3 an den Spannprofilen 4 mechanisch fixiert, während das entgegengesetzte, mit der Isolationsfolie verbundene Kopfteilende allseitig frei beweglich ist. Die Schraubenfedern 3 können somit praktisch allen Formveränderungen der Isolationsfolien 2 relativ zu den Spannprofilen 4 optimal folgen bzw. diese kompensieren.In the clamping profiles 4, the coil springs 3 are anchored in a longitudinal groove 4.2 with undercut flanks. Her last turn on her foot part is slightly expanded compared to the other turns and engages with it in the undercuts of the longitudinal groove 4.2. This type of fastening mechanically fixes the foot part end of the coil springs 3 to the clamping profiles 4, while the opposite head part end connected to the insulating film is freely movable on all sides. The helical springs 3 can thus optimally follow or compensate for practically all changes in shape of the insulating foils 2 relative to the clamping profiles 4.

Als Material für die Spannprofile kann z.B. Aluminium verwendet werden. Im Hinblick auf seine wesentlich geringere Wärmeleitung wäre jedoch ein Kunststoff von Vorteil.Aluminum, for example, can be used as the material for the clamping profiles. In view of its significantly lower heat conduction, a plastic would be an advantage.

Wie in der Zeichnung deutlich zu erkennen ist, sind die Schraubenfedern 3 auf Grund der erforderlichen Vorspannung der Isolationsfolien 2 quer zu ihrer Längserstreckung gebogen. Damit sie etwa senkrecht auf den Folien 2 enden, sind sie mit ihrem Fussteil etwas schräg gegenüber den Folienebenen in den Spannprofilen 4 fixiert.As can be clearly seen in the drawing, the coil springs 3 are bent transversely to their longitudinal extent due to the required pretensioning of the insulating foils 2. So that they end approximately vertically on the foils 2, they are fixed with their foot part somewhat obliquely in relation to the foil planes in the clamping profiles 4.

Bedingt durch die Biegung quer zu ihrer Längserstreckung sind die Windungen der Schraubenfedern 3 teilweise voneinander abgehoben und weisen lediglich krümmungsinnenseitig praktisch nur noch Punktkontakte miteinander auf. Laterale Formveränderungen der Isolationsfolien 2 in Längsrichtung der Spannprofile haben dadurch nur reibungslose Dreh- oder Kippbewegungen der einzelnen Windungen um diese Punktkontakte zur Folge.Due to the bend transverse to its longitudinal extent, the turns of the coil springs 3 are partially lifted from one another and only have point contacts with one another on the inside of the curvature. Lateral changes in shape of the insulation foils 2 in the longitudinal direction of the clamping profiles only result in smooth rotation or tilting movements of the individual turns around these point contacts.

Zur eindeutigen Festlegung der Folienebenen dienen die vorderen Kanten 4.3 von mit 4.4 bezeichneten Schenkelleisten an den Spannprofilen 4. Gegenüber diesen Kanten 4.3 sind die Verbindungsstellen zwischen den Isolationsfolien 2 und den Schraubenfedern 3 aus den Folienebenen heraus etwas zurückversetzt.The front edges 4.3 of leg strips denoted by 4.4 on the clamping profiles 4 serve to uniquely define the film levels. Compared to these edges 4.3, the connection points between the insulating films 2 and the coil springs 3 are set back somewhat from the film levels.

Die als Verbindungsflächen verwendeten Seitenflächen 4.1 der Spannprofile 4 sind verhältnismässig grossflächig ausgebildet, um eine stabile Verklebung zu gewährleisten. Als Kleber ist z.B. ein Acrylat-Haftkleber geeignet, der in Form eines mit einem Schutzstreifen versehenen Montageklebebandes 9 vor der eigentlichen Herstellung der Klebverbindung auf die flachen Seitenflächen 4.1 der Spannprofile 4 aufgebracht werden kann.The side surfaces 4.1 of the clamping profiles 4 used as connecting surfaces have a relatively large area, to ensure a stable bond. An acrylate pressure-sensitive adhesive is suitable as an adhesive, for example, which can be applied to the flat side surfaces 4.1 of the clamping profiles 4 in the form of a mounting adhesive tape 9 provided with a protective strip before the adhesive connection is actually made.

Dicke, Elastizität und Kriechverhalten der Klebeschicht sind so gewählt, dass diese Scherspannungen elastisch aufzunehmen vermag, die durch nur vorübergehende, ungleiche Wärmedehnungen von Scheibe und Spannprofil oder durch entsprechende mechanische Erschütterungen verursacht werden, andererseits jedoch unter der Wirkung der latent vorhandenen Folienspannung kein Kriechen zeigt. Vorzugsweise ist die Dicke der Klebeschicht etwa entsprechend den maximal zu erwartenden relativen Verschiebungen zwischen Scheibe und Spannprofil bemessen.The thickness, elasticity and creep behavior of the adhesive layer are selected so that they can absorb elastic shear stresses that are caused by only temporary, uneven thermal expansion of the washer and clamping profile or by corresponding mechanical vibrations, but on the other hand do not show any creep under the effect of the latent film tension. The thickness of the adhesive layer is preferably dimensioned approximately according to the maximum relative displacements to be expected between the pane and the clamping profile.

Die Möglichkeit, die Verbindung zwischen den Spannprofilen 4 und den Scheiben 1 als tragende Verklebung auszubilden, ergibt sich direkt als Folge der Verwendung der Schraubenfedern 3 zum Spannen der Folien 2 auf die beschriebene Art, weil hierbei praktisch keine Reibungskräfte zum Spannen der Folien überwunden werden müssen. Es ist wegen der sich ergebenden geringen Gesamtspannung auch nicht erforderlich, aus den Spannprofilen 4 einen tragenden Spannrahmen zu bilden. Es ist sogar möglich, über den Umfang der Isolationsfolien mehrere Spannprofile ohne direkte gegenseitige Verbindung und mit Ausgleichsspalten an den Stossstellen miteinander zu kombinieren. Eine dichtungstechnisch günstige Ausführungsform für ein rechteckiges Fenster ergibt sich z.B. aus der Kombination von zwei u-förmig gebogenen Spannprofilen, weil deren Stossstellen auf zwei Längsseiten des Rechteckquerschnitts und nicht in den dichtungstechnisch kritischen Ecken zu liegen kommen.The possibility of forming the connection between the clamping profiles 4 and the panes 1 as a load-bearing glue arises directly as a result of the use of the coil springs 3 for tensioning the foils 2 in the manner described, since practically no frictional forces have to be overcome for tensioning the foils . It is also not necessary because of the resulting low total tension to form a load-bearing tension frame from the tension profiles 4. It is even possible to fit several clamping profiles over the circumference of the insulation films without direct mutual connection and with compensating gaps to combine the joints. A seal-technically favorable embodiment for a rectangular window results, for example, from the combination of two U-shaped curved clamping profiles, because their abutments come to rest on two long sides of the rectangular cross-section and not in the seal-critical corners.

Das Abstandsprofil 5 ist mit beiden Spannprofilen 4 nach Art von Nut- und Federverbindungen 5.4 im Eingriff, wobei Federleisten 5.5 das selbständige Lösen dieser Eingriffsverbindungen verhindern.The spacer profile 5 is in engagement with the two clamping profiles 4 in the manner of tongue and groove connections 5.4, with spring strips 5.5 preventing the independent loosening of these engagement connections.

Unter anderem aus optischen Gründen sind die Schenkelleisten 4.4 an den Spannprofilen und die Oberseite der Längskammer 5.2 des Abstandsprofils 5 zum Innenraum des Verglasungselements hin mit flachen Oberflächen versehen und auf gleicher Höhe sowie mit geringem gegenseitigem Abstand angeordnet. Zwischen ihnen ist jeweils nur ein schmaler Spalt für den Durchtritt der Isolationsfolien 2 belassen.For optical reasons, among other things, the leg strips 4.4 on the clamping profiles and the top of the longitudinal chamber 5.2 of the spacing profile 5 are provided with flat surfaces towards the interior of the glazing element and are arranged at the same height and with a small mutual distance. Only a narrow gap is left between them for the passage of the insulation foils 2.

Das Dichtungsband 6 ist ein 0,05 mm dickes Band aus rostfreiem (austenitischem) Stahl. Zum Einkleben des Dichtungsbandes zwischen die Scheiben ist ein bei hoher Temperatur schmelzender Butylkleber geeignet. Im Unterschied zu dem Kleber zum Ankleben der Spannprofile muss dieser keine Kräfte aufnehmen. In den Randbereichen an den Scheiben sind jeweils durch die aus der Zeichnung erkennbare Formgebung des Abstandsprofils sowie der Spannprofile Längsrillen 7 ausgebildet, in welche der Kleber hineinfliessen und die Trennspalte zwischen dem Abstandsprofil 5 und den Spannprofilen 4 sowie zwischen diesen und den Scheiben gut abdichten kann. Ausser diesen Randbereichen besteht zwischen dem Abstandsprofil 5 und dem Dichtungsband 6 keine klebende Verbindung.The sealing tape 6 is a 0.05 mm thick tape made of stainless (austenitic) steel. A butyl adhesive that melts at high temperature is suitable for gluing the sealing tape between the panes. In contrast to the adhesive for gluing the clamping profiles, this does not have to absorb any forces. In the edge areas on the panes, the shape of the spacer profile and the shape of the spacer can be seen from the drawing Clamping profiles formed longitudinal grooves 7, into which the adhesive can flow and can seal the separation gaps between the spacer profile 5 and the clamping profiles 4 and between these and the washers well. Apart from these edge areas, there is no adhesive connection between the spacer profile 5 and the sealing tape 6.

Das vorstehend beschriebene Verglasungselement zeichnet sich durch eine einfache Konstruktion aus. Vor allem die Schraubenfedern sind ausgesprochen kostengünstige Teile. Das Fenster ist mit geringem fertigungstechnischem Aufwand in nur wenigen automatisierbaren Arbeitsschritten herstellbar.The glazing element described above is characterized by a simple construction. The coil springs in particular are extremely inexpensive parts. The window can be manufactured in a few work steps that can be automated, with little manufacturing effort.

Gegenüber dem beschriebenen Ausführungsbeispiel sind natürlich Abwandlungen möglich. So könnte beispielsweise eine der beiden Isolationsfolien 2 weggelassen werden. Anstelle von Schraubenfedern könnten andere Federelemente mit ähnlichen Federeigenschaften verwendet werden, z.B. ein in sich um 90° verdrilltes Federband oder direkt an den Spannprofilen angeformte Federzungen. Die Folie könnte anstatt durch Anschweissen auch durch Kleben mit den Schraubenfedern oder den jeweils verwendeten Federelementen verbunden werden.Modifications are of course possible compared to the exemplary embodiment described. For example, one of the two insulation foils 2 could be omitted. Instead of coil springs, other spring elements with similar spring properties could be used, e.g. a spring band twisted by 90 ° or spring tongues molded directly onto the clamping profiles. Instead of being welded on, the film could also be connected by gluing to the helical springs or the spring elements used in each case.
