Description

Die Erfindung betrifft einen Kantenschutz für Mehrscheiben-Isolierglas gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to edge protection for multi-pane insulating glass according to the preamble of patent claim 1.

Isolierglas besteht aus zwei Glasscheiben, die durch einen randlich zwischengefügten Steg auf Abstand gehalten sind. Dieser Steg bzw. Abstandhalter ist ein Hohlprofil, in dem ein Entfeuchtungsmittel untergebracht ist, welches über Perforationen mit dem Zwischenraum zwischen den Scheiben in Verbindung steht. An dieses Entfeuchtungsmittel wird also die anfänglich in dem Zwischenraum vorhandene Luftfeuchtigkeit gebunden. Es muß nun aber dafür gesorgt werden, daß in den Zwischenraum keine Feuchtigkeit mehr eintreten kann, insbesondere muß jeglicher Luftaustausch unterbunden werden.Insulating glass consists of two panes of glass, which are kept at a distance by a web between the edges. This web or spacer is a hollow profile, in which a dehumidifying agent is accommodated, which is connected to the space between the panes via perforations. The air moisture initially present in the intermediate space is thus bound to this dehumidifier. However, it must now be ensured that no more moisture can enter the interspace, in particular any air exchange must be prevented.

Zu diesem Zweck ist auf dem etwas nach innen versetzten Abstandhalter eine Dichtungsmasse (Handelsname Tiocol) aufgebracht.For this purpose, a sealing compound (trade name Tiocol) is applied to the spacer, which is slightly offset to the inside.

Ferner ist bei Isolierglas ein umlaufender Kantenschutz für die jeweils seitlich/außenliegenden Kanten erforderlich, ohne den das Glas zu leicht beschädigt, verkratzt oder zerbrochen werden würde, beispielsweise wenn ein Sandkorn, Nagel oder dergleichen Fremdkörper zwischen Glaskante bzw. -Rücken und Unterlage (meist Holzklotz) gelangt oder wenn das Glas gar mit der Kante auf einen Fußboden abgesetzt wird.Furthermore, in the case of insulating glass, all-round edge protection is required for the side / outer edges without which the glass would be too easily damaged, scratched or broken, for example if a grain of sand, nail or similar foreign body between the glass edge or back and base (usually wooden blocks ) or if the edge of the glass is placed on a floor.

Der Kantenschutz ist auch schon bei der Fabrikation erforderlich, um die noch plastische Dichtungsmasse gleich nach dem Aufbringen abzudecken, so daß sie nicht abfließen bzw. verformt werden kann, aber das Isolierglas sogleich gehandhabt, also transportiert, seitlich gestapelt usw. werden kann.The edge protection is also necessary during manufacture to cover the still plastic sealant immediately after application, so that it cannot flow off or be deformed, but the insulating glass can be handled immediately, i.e. transported, stacked on the side, etc.

Dieser Kantenschutz besteht bisher meist aus einem U-förmigen Aluminiumprofil von ca. 0,5 mm Dicke, dessen beide Schenkel randlich am Glas und dessen Steg an der Dichtungsmasse anliegen.This edge protection has so far mostly consisted of a U-shaped aluminum profile of approx. 0.5 mm thickness, the two legs of which lie against the edge of the glass and the web of which rests against the sealing compound.

Das Aluminiumprofil haftet zwar gut an der Dichtungsmasse und auch am Glas und bringt auch genügenden Kantenschutz, es hat aber folgende Nachteile:

  • Das Aluminiumprofil bildet eine Kältebrücke zwischen der Außensche
be und der Innenscheibe. An der Innenscheibe hat man daher randlich umlaufend eine kältere Zone, an der Feuchtigkeit aus dem Innenraum (Zimmer) kondensiert.The aluminum profile adheres well to the sealing compound and also to the glass and also provides sufficient edge protection, but it has the following disadvantages:
  • The aluminum profile forms a thermal bridge between the A ußensche
be and the inner pane. There is therefore a colder area around the edge of the inner pane, where moisture condenses from the interior (room).

Diese Feuchtigkeit an der Scheibe ist unschön. Vor allem aber bildet sich Kondenswasser in dem Glasfalz, d.h. innerhalb der Einfassung bzw. Einrahmung des Glases. (Aufgrund der sogenannten "Verklotzung" beim Einsetzen des Isolierglases in den Fensterflügel ergibt sich ein jeweils ca. 3 mm starker innerer Hohlraum.) Dieses Kondenswasser vermindert die Haltbarkeit.des Rahmens. Auch kann das Wasser an der Glasleiste herauslaufen und es bilden sich unschöne Schmutzrückstände. Insbesondere besteht immer die Gefahr, daß das ständig vorhandene Kondenswasser in den Scheibenzwischenraum eindringt. Ferner besteht die Gefahr eines Verkratzens bei dem Aneinanderlegen von Isolierglasscheiben, insbesondere wenn die scharfkantigen Gehrungsschnitte an dem Aluminium-Kantenschutz-Profil an einer Glasscheibe entlanggleiten.This moisture on the pane is unsightly. Above all, however, condensation forms in the glass rebate, i.e. within the frame or framing of the glass. (Due to the so-called "blocking" when inserting the insulating glass in the window sash, there is an approx. 3 mm thick inner cavity.) This condensed water reduces the durability of the frame. The water can also run out of the glazing bead and form unsightly dirt residues. In particular, there is always the risk that the constantly present condensation water penetrates into the space between the panes. There is also the risk of scratching when insulating glass panes are placed next to one another, in particular if the sharp-edged miter cuts on the aluminum edge protection profile slide along a glass pane.

Aus der DE OS 24 54 530 ist bereits ein gemäß dem Oberbegriff vorausgesetztes Kantenschutzprofil bekanntgeworden, welches statt aus Aluminium aus elastischem Kunststoff besteht. Die beiden Profilschenkel sollen dabei dank ihrer Federkraft mit strammem Sitz am Rand der Glasscheiben anliegen. Ferner ist auf der Innenseite des Profil-Steges eine Schwalbenschwanz-Feder vorgesehen, die in die Dichtungsmasse zwischen den Scheiben eingreifen und so die Haftung des Kantenprofils verbessern soll. Dank des Kunststoffmaterials wird zwar die Wärmeleitung im Vergleich mit einem MetallProfil weitgehend herabgesetzt und damit auch die erwähnte Kondenswasserbildung vermindert. Jedoch ist die Haftung oder Verankerung dieses Kantenschutzprofiles an dem Zwei-Scheiben-Glas mangelhaft und vor allem kann Feuchtigkeit in die Abdichtung eindringen, und zwar insbesondere in den Spalt oder in die Fuge zwischen diesem Kantenschutzprofil und den Glasscheiben.DE OS 24 54 530 has already disclosed an edge protection profile which is a prerequisite for the preamble and which consists of elastic plastic instead of aluminum. Thanks to their spring force, the two profile legs should lie tightly against the edge of the glass panes. Furthermore, a dovetail spring is provided on the inside of the profile web, which in the Insert the sealing compound between the panes and thus improve the adhesion of the edge profile. Thanks to the plastic material, the heat conduction is largely reduced in comparison with a metal profile and thus the aforementioned condensation is reduced. However, the adhesion or anchoring of this edge protection profile to the two-pane glass is inadequate and, above all, moisture can penetrate into the seal, in particular into the gap or into the joint between this edge protection profile and the glass panes.

Demgegenüber liegt der Erfindung die Aufgabe zugrunde, einen Kantenschutz dieser Art zu schaffen, bei dem das Kantenschutzprofil ausreichend fest an dem Zwei-Scheiben-Glas (bzw. Mehrscheibenglas) befestigt bzw. verankert ist und bei dem das erwähnte Eindringen von Feuchtigkeit weitgehend vermieden ist. -Die Lösung dieser Aufgabe ist in dem Kennzeichnungsteil des Patentanspruchs angegeben. Danach liegen die beiden Schenkel des Kantenschutzprofils mit je einem verdickten, fußförmigen Anlageteil an dem Glas an, wobei vor allem jeweils zwischen einem Anlageteil und dem Profilsteg ein im Querschnitt dreieckiger Hohlraum gebildet ist. Durch diesen Hohlraum an der Wurzel bzw. im Scheitel zwischen Profilschenkel und Steg wird zwar die elastische Federkraft vermindert, jedoch wird dies weit mehr als ausgeglichen dadurch, daß bei dem Anlegen des Kantenschutzprofils die in entsprechender Menge aufgetragene Dichtungsmasse jeweils in diesen dreieckigen Hohlräum eindringt und vor allem in den Zwickelraum oder die Hinterschneidung an je einem Anlageteil eindringt, so daß also der Anlageteil mit der Dichtungsmasse verzahnt wird und somit fest in Anlage gegen das Glas gehalten wird. Die erwähnten Hinterschneidungen sind also nicht bzw. nicht nur an dem Steg, sondern unmittelbar an dem Anlageteil vorgesehen, so daß sie den Anlageteil unmittelbar in Anlage gegen das Glas halten. Es kann sich also gar nicht erst ein Spalt bilden, in den nach und nach mehr und mehr Wasser eindringen könnte. Die Haftung bzw. Verankerung ist von vorneherein so groß, daß das Mehrscheibenglas ohne weiteres an dem Kantenschutzprofil angehoben und gehandhabt werden kann. Günstig ist ferner, daß gerade die besonders empfindlichen Kanten der Glasscheiben durch die weichere, in die besagten Zwickelräume eingedrungene Dichtungsmasse geschützt sind, also der Kantenschutz verbessert ist.In contrast, the invention has for its object to provide an edge protection of this type, in which the edge protection profile is sufficiently firmly attached or anchored to the two-pane glass (or multi-pane glass) and in which the aforementioned penetration of moisture is largely avoided. -The solution to this problem is specified in the characterizing part of the claim. Thereafter, the two legs of the edge protection profile each have a thickened, foot-shaped contact part on the glass, a triangular cross-section being formed between each contact part and the profile web. Although the elastic spring force is reduced by said cavity at the root or at the apex between the profile legs and the web, but this is far more than offset by the fact that during the application of the K penetrates ante protection profile, the applied in the appropriate amount of sealing composition respectively in these triangular Hohlräum and penetrates especially into the gusset or the undercut on each plant part, so that the plant part is interlocked with the sealing compound and is thus held firmly against the glass. The undercuts mentioned are therefore not provided or not only on the web, but directly on the contact part, so that they hold the contact part directly against the glass. A gap cannot form at all, into which more and more water could gradually penetrate. The adhesion or anchoring is so great from the outset that the multi-pane glass can be easily lifted and handled on the edge protection profile. It is also advantageous that the particularly sensitive edges of the glass panes are protected by the softer sealing compound which has penetrated into the said gusset spaces, that is to say the edge protection is improved.

Vorteilhaft verjüngen, sich die Anlageflächen zu ihren. freien Enden hin, damit beim Transport nicht etwa ein anderes Mehr-Scheiben-Glas auf die relativ empfindlichen Stirnflächen (25,26 in Fig. 1) abgesetzt werden kann.Advantageously rejuvenate the contact surfaces to theirs. free ends so that another multi-pane glass cannot be placed on the relatively sensitive end faces (25, 26 in FIG. 1) during transport.

Wenn noch eine weitere Verbesserung der Befestigung oder Verankerung des Kantenschutzprofils, und zwar von dessen Anlageteilen an dem Glas gewünscht wird, so kann man zu diesem Zweck zusätzlich zu der erwähnten Hinterschneidung noch eine weitere solche Hinterschneidung bzw. einen zackenförmigen Steg oder eine Nase zwischen Anlageteil und Profilsteg vorsehen, der (die) ebenso wirkt, also verankert wird wie die erstgenannte Hinterschneidung oder Nase. Allerdings besteht hierbei die Schwierigkeit, daß die andere, zusätzliche Hinterschneidung oder Nase das Einfließen der Tiocol-Dichtungsmasse hinter die erstgenannte Hinterschneidung hindern würde:

  • Um diese Behinderung zu vermeiden, ist die Höhe dieser weiteren Stege geringer als die Höhe der erstgenannten Hinterschneidung, so daß ein genügender Zwischenraum zwischen diesem weiteren Steg und der Glasscheibe zum Durchfließen der Dichtungsmasse beim Anlegen des Kantenschutzprofils verbleibt.
If yet a further improvement of the attachment or anchoring ante protection profile of K, and it is desired indeed of the plant parts to the glass, so it is possible for this purpose in addition to the aforementioned undercut yet another such undercut or a serrated ridge or lug between the system part and provide a profile web that also works, i.e. is anchored like the first undercut or nose. However, the difficulty here is that the other, additional undercut or nose would prevent the Tiocol sealant from flowing in behind the first undercut:
  • In order to avoid this hindrance, the height of these further webs is less than the height of the first undercut, so that there is sufficient space between this further web and the glass pane for the sealant to flow through when the edge protection profile is applied.

Die beiden Glasscheiben 1,2 eines Isolierglases sind wie üblich durch einen.hohlen Abstandhalter 3 in dem gewünschten Abstand voneinander gehalten. Ein in dem Abstandhiater 3 untergebrachtes Entfeuchtungsmittel.4 steht über Perforationen 5 mit dem Zwischenraum 6 zwischen den Scheiben 1,2 in Verbindung. Der Abstandhalter 3 ist etwas nach innen versetzt. Auf jede der vier Schmalseiten eines solchen Zwei.Scheiben-Isolierglases ist je ein Kantenschutz-Profil 7 aufgebracht, dessen beide Schenkel 8,9 je eine Glasscheibe randlich übergreifen und dessen Steg 10 die Schmalseite bzw. Stirnfläche des Zwei-Scheiben-Glases abdeckt. Das Kantenschutz-Profil besteht aus Kusntstoff.und weist an seiner Innenseite im Abstand voneinander drei angeformte schwalbenschwanzförmige Federn 11,12,13 auf, die in der Dichtungsmasse 14 eingebettet bzw. verankert sind. Das Kantenschutzprofil wird angebracht, so lange die Dichtungsmasse 14 noch plastisch ist; dabei ist darauf zu achten, daß gerade soviel Dichtungsmasse angebracht wird, daß die Hohlräume bzw. Hinterschneidungen seitlich der Federn ausgefüllt werden. Die beiden seitlichen Federn 11, 13 liegen an den Stirnflächen der beiden Glasscheiben an. Die beiden Schenkel 8,9 liegen mit je einem (im Querschnitt) fußförmigen Anlageteil 17,18 randlich - mit Abstand von der seitlich äußeren Kante 15, 15 - an je einer Scheibe 1,2 an. Zwischen dem Anlageteil 17, 18 und dem Steg 10 erstreckt sich ein verdünnter Verbindungsteil 19, 20. Es istsomit je ein (im Querschnitt) dreieckiger Hohlraum 21,22 gebildet, in den die zugehörige Kante 15,16 der Scheibe eingreift.The two glass panes 1, 2 of an insulating glass are, as usual, held at the desired distance from one another by a hollow spacer 3. A accommodated in the Abstandhiater 3 E ntfeuchtungsmittel.4 is via perforations 5 with the gap 6 between the discs 1,2 in connection. The spacer 3 is offset somewhat inwards. An edge protection profile 7 is applied to each of the four narrow sides of such a two-pane insulating glass, the two legs 8, 9 of which each overlap a pane of glass and whose web 10 covers the narrow side or end face of the two-pane glass. The edge protection profile consists of plastic and has on its inside three molded dovetail-shaped springs 11, 12, 13 which are embedded or anchored in the sealing compound 14 at a distance from one another. The edge protection profile is attached as long as the sealing compound 14 is still plastic; It is important to ensure that enough sealing compound is applied to fill the cavities or undercuts on the side of the springs. The two lateral springs 11, 13 rest on the end faces of the two glass panes. The two legs 8, 9 each have a (in cross-section) foot-shaped contact part 17, 18 on the edge - at a distance from the laterally outer edge 15, 15 - on a disk 1, 2. A thinned connecting part 19, 20 extends between the contact part 17, 18 and the web 10. A triangular cavity 21, 22 (in cross section) is thus formed in each case, in which the associated edge 15, 16 of the disk engages.

Dieser Hohlraum ist mit Dichtungsmasse 14 ausgefüllt, womit ein zusätzlicher Polstereffekt erreicht wird. Diese Dichtungsmasse greift auch in je eine Hinterschneidung 23,24 ein, die zwischen Verbindungsteil und Anlageteil ausgebildet ist; durch diese Hinterschneidung bzw. einspringende Ecke wird das Anlageteil 17, 18 an der Scheibe festgehalten, womit die Haftung verbessert wird. Durch diese Hinterschneidung sowie durch die übrigen einspringenden Eckräume wird außerdem der Weg vergrößert, den von außen eindringende Feuchtigkeit zurückzulegen hätte.This cavity is filled with sealing compound 14, whereby an additional cushioning effect is achieved. This sealing compound also engages in an undercut 23, 24, which is formed between the connecting part and the contact part; by means of this undercut or protruding corner, the contact part 17, 18 is held on the pane, which improves the adhesion. This undercut, as well as the other protruding corner spaces, also increases the path that moisture that would have penetrated from the outside would have to be covered.

Die beiden Anlageteile 17,18 verjüngen sich zu ihrem freien Ende hin, so daß nicht etwa versehentlich ein anderes Isolierglas auf die verbleibende schmale Stirnfläche 25, 26 abgesetzt werden kann.The two system parts 17, 18 taper towards their free end, so that another insulating glass cannot inadvertently be placed on the remaining narrow end face 25, 26.

Der erfindungsgemäße Kunststoff-Kantenschutz ist weicher als das bisherige Alu-Material, so daß an den Gehrungsschnitten 27 (an den Ecken) aneinandergeratene Scheiben nicht zerkratzt werden können.The plastic edge protector according to the invention is softer than the previous aluminum material, so that panes that have come together at the miter cuts 27 (at the corners) cannot be scratched.

Gemäß Fig. 3 sind - außer den beiden Hinterschneidungen 23, 24 noch eine weitere Hinterschneidung bzw. je ein Zwickel 30 durch je eine vorstehende Nase 29 oder Steg 10 gebildet, die auf dem verdünnten Verbindungsteil 19, 20 angeformt ist. Die Höhe H2 dieser weiteren Nase ist dabei geringer als die Höhe H2 der erstgenannten Hinterschneidung 23, 24 bzw. der ersten Nase 23a,24a, so daß beim Aufsetzen des Kantenschutzprofils ein Zwischenraum zwischen der Nase 29 und der Glasscheibe 1,2 verbleibt, so daß Tiocol-Dichtungsmasse in die erste Hinterschneidung 23, 24 (bzw. Zwickelraum) hineinfließen kann. Durch diese zusätzlichen Zwikkelräume bzw. Nasen 29 wird die Haftung verbessert und insbesondere wird der Weg weiter vergrößert, den von außen eindringende Feuchtigkeit zurückzulegen hätte. Hierauf, auf dieses Vermeiden des Eindringens von Feuchtigkeit kommt es, wie schon erwähnt, in erster Linie an. Und zwar ist es so, daß die Tiocol-Dichtungsmasse gut an-der Fensterscheibe, aber weniger gut an dem Kunststoffprofil haftet. Zur weiteren Verbesserung dieser haftung kann das Kunststoffprofil aufgerauht sein, insbesondere an den Innenflächen oder Anlageflächen der Anlageteile 17,18. Dies kann beispielsweise durch Riefen oder Längsrillen 31 geschehen, die beim Extrudieren der Profile durch entsprechende Unebenheiten an der Extrusionsform gebildet werden.According to FIG. 3, apart from the two undercuts 23, 24, a further undercut or a gusset 30 is formed by a projecting nose 29 or web 10, which is formed on the thinned connecting part 19, 20. The height H 2 of this further nose is less than the height H2 of the first undercut 23, 24 or the first nose 23a, 24a, so that when the edge protection profile is placed there remains a space between the nose 29 and the glass pane 1, 2, so that T iocol sealant can flow into the first undercut 23, 24 (or Z winding space). Adhesion is improved by these additional double spaces or lugs 29 and, in particular, the path is further increased, which would have to cover the moisture penetrating from the outside. This, as already mentioned, is primarily about avoiding the penetration of moisture. The fact is that the Tiocol sealant adheres well to the window pane, but less well to the plastic profile. To further improve this adhesion, the plastic profile can be roughened, in particular on the inner surfaces or contact surfaces of the contact parts 17, 18. This can be done, for example, by scoring or longitudinal grooves 31, which are formed by corresponding unevenness in the extrusion mold during the extrusion of the profiles.

Gemäß Fig. 3 ist nur eine einzige Verankerungs-Feder 12 auf der Innenseite des Steges 10 vorgesehen. Die weitere oder zusätzliche Verankerung erfolgt, wie erwähnt, durch die Hinterschneidungen 23, 24 oder Nasen 29. Gegenüber dieser Feser 12 ist auf der Außenseite des Steges 1.0 eine Einbuchtung 28 vorgesehen.Ig according F. 3, only a single anchoring spring 12 is provided on the inside of the web 10. The further or additional anchoring takes place, as mentioned, through the undercuts 23, 24 or lugs 29. An indentation 28 is provided on the outside of the web 1.0 opposite this spring 12.

Die Anlageteile 17, 18 sind im entsprannten Zustand, also vor der Montage, etwas nach innen geneigt, d.h. der Abstand zwischen ihren Enden (Stirnflächen 25, 26) ist geringer als die Dicke des Zwei-Scheiben-Glases 1,2; außerdem besteht das Kantenschutz- profil aus elastischem Kunststoff. Dank der Verankerung mittels der Hinterschneidungen 23, 24 bzw. Nasen 29 können Verankerungsmittel, insbesondere die Schwalbenschwanzfeder 12 auf der Innenseite des Steges 10 völlig entfallen, wie dies in Fig. 4 gezeigt ist.The system parts 17, 18 are in the relaxed state, ie before assembly, slightly inclined inwards, ie the distance between their ends (end faces 25, 26) is less than the thickness of the Two-pane glass 1.2; the edge protection profile is also made of elastic plastic. Thanks to the anchoring by means of the undercuts 23, 24 or lugs 29, anchoring means, in particular the dovetail spring 12 on the inside of the web 10, can be completely dispensed with, as is shown in FIG. 4.
