Abstract

The supporting insert for window-panes (15) of multiple insulating glazings for windows, doors or the like has a particular cross-section enabling a better bending, sealing and filling with a desiccating material. Said cross-section comprises on the outer side of the glazing a hollow profile (2) connected to the inner wall (6) and which is narrower than a forked profile (3) on the inner side. These arrangements enable a superposition of a plurality of profiles with a reduced package volume and a faster filling with a desiccant material. Furthermore, the sealing of the window-panes (15) is improved since the profile area (2) which is narrower in bending conditions is not in contact with the window-panes (15).

Description

Die Erfindung bezieht sich auf einen Abstandhalter aus Metall oder Kunststoff für Scheiben für Mehrfach-Isoliergläser für Fenster, TUren oder dgl., entsprechend den Merkmalen des Oberbegriffes des Hauptanspruches.The invention relates to a spacer made of metal or plastic for panes for multiple insulating glasses for windows, doors or the like, according to the features of the preamble of the main claim.

Abstandhalter dieser Art sind durch die DE-PS 29 29 544 bekannt geworden. Damit wird die Aufgabe gelöst, beim Biegen solcher Abstandhalter keine erkennbaren Verformungen der Wandungen entstehen zu lassen, um damit auch die Abdichtung zwischen den Glasscheiben und dem Abstandhalter zu verbessern.Spacers of this type are known from DE-PS 29 29 544. This solves the problem of not causing any visible deformations of the walls when bending such spacers in order to improve the seal between the glass panes and the spacer.

In der Praxis hat sich nun gezeigt, daß noch Veranlassung besteht, die Querschnittsgestaltung der Abstandhalter zu verbessern, um das Biegen zu erleichtern und zu vervollkommnen, die Abdichtung der Abstandhalter gegenüber den Glasscheiben weiter zu verbessern und schließlich auch das Füllen der Hohlräume der Abstandhalter mit dem feuchtigkeitsaufnehmenden Material zu erleichtern und zu beschleunigen.In practice, it has now been shown that there is still reason to improve the cross-sectional design of the spacers in order to facilitate and perfect the bending, to further improve the sealing of the spacers with respect to the glass panes and finally also to fill the cavities of the spacers with the to facilitate and accelerate moisture-absorbing material.

Aufgabe der Erfindung ist es daher, den vorbekannten Abstandhalter dahingehend zu verbessern, daß seine Handhabung wesentlich erleichtert wird.The object of the invention is therefore to improve the known spacer in such a way that its handling is made considerably easier.

Diese Aufgabe wird mit den kennzeichnenden Merkmalen des Hauptanspruches gelöst.This object is achieved with the characterizing features of the main claim.

Danach wird der erfindungsgemäße Abstandhalter aus zwei Profilabschnitten ungleicher Breite gebildet, die sich diesseits und jenseits der Innenwand erstrecken. Der nach außen gerichtete, den geschlossenen Hohlraum aufweisende Profilbereich ist dabei schmäler als der durch die gabelförmigen Schenkel gebildete Profilbereich. Da der Hohlprofilbereich außerdem trapezförmig gestaltet ist, ergibt sich eine Stapelbarkeit der erfindungsgemäßen Abstandhalter, die durch entsprechende Bemessung des Profilquerschnittes so weit getrieben werden kann, daß im Stapel die Innenwand des einen Profils an der Außenwand des anderen Profiles zur Anlage kommt.. Damit ergibt sich aber auch eine wesentliche Beschleunigung des FUllvorganges der Profilhohlräume mit dem feuchtigkeitsaufnehmenden Material, weil die Befüllung an einem Stapel aneinandergereihter Abstandhalter vorgenommen werden kann.Thereafter, the spacer according to the invention is formed from two profile sections of unequal width, which extend on both sides of the inner wall. The outwardly directed profile area, which has the closed cavity, is narrower than the profile area formed by the fork-shaped legs. Since the hollow profile area is also designed to be trapezoidal, the spacers according to the invention can be stacked, which can be driven so far by appropriate dimensioning of the profile cross section that the inner wall of one profile comes into contact with the outer wall of the other profile in the stack but also a significant acceleration of the filling process of the profile cavities with the moisture-absorbing material, because the filling can be carried out on a stack of spacers lined up.

Zugleich ergibt sich aus dem Querschnitt des erfindungsgemäßen Profiles eine wesentliche Verbesserung der Abdichtwirkung zwischen den Glasscheiben und dem Abstandhalter. An die längsdurcklaufende, nach innen eingebauchte hohlkehlenförmige Nut, in welche ein Dichtungsprofil, insbesondere in Form einer Butylprofilschnur, eingelegt wird, grenzt nämlich der durch die gabelförmigen Schenkel gebildete Profilbereich, an dessen Außenflächen die Scheiben zur Anlage kommen. Das beim Erwärmen teigig oder pastös werdende Dichtungsmittel findet am Übergang der Nut zur Außenfläche der Schenkel eine natürliche Barriere, die es nicht zu überwinden vermag. Folglich kann das Dichtungsmittel nicht entlang der Schenkel des Abstandhalters nach innen vordringen . Wohl aber kann das Dichtungsmittel nach außen wegen der geringeren Breite des Hohlprofilbereiches wandern bzw. kriechen und eine verbesserte Dichtungswirkung erzielen, weil es unter dem Druck der anliegenden Scheiben verquetscht wird.At the same time, the cross section of the profile according to the invention results in a significant improvement in the sealing effect between the glass panes and the spacer. The profile area formed by the fork-shaped legs, on the outer surfaces of which the disks come into contact, borders on the longitudinally running, inwardly recessed, groove-shaped groove into which a sealing profile, in particular in the form of a butyl profile cord, is inserted. The sealant, which becomes doughy or pasty when heated, finds a natural barrier at the transition from the groove to the outer surface of the legs, which it cannot overcome. As a result, the sealant cannot penetrate inward along the legs of the spacer. However, the sealant can migrate or crawl outwards because of the smaller width of the hollow profile area and achieve an improved sealing effect because it is squeezed under the pressure of the adjacent panes.

Schließlich vermittelt die längsdurchlaufende, nach innen eingebauchte hohlkehlenförmige Nut, welche in der neutralen Zone des Abstandhalter-Profiles liegt, eine noch weiter verbesserte, beim Biegen des Abstandhalters entstehende Formgebung, weil die den Hohlraum umschließenden Wände des Abstandhalters nicht mehr zur unmittelbaren Anlage an die Glasscheiben gelangen.Finally, the longitudinally continuous, inwardly recessed groove-shaped groove, which lies in the neutral zone of the spacer profile, provides an even better shape which arises when the spacer is bent, because the walls of the spacer which enclose the cavity are no longer able to abut directly against the glass panes reach.

In den UnteransprUchen sind vorteilhafte Weiterbildungen des erfindungagemäßen Abstandhalters offenbart, die ebenfalls einer verbesserten Handhabung der Abstandhalter beim Herstellen und Montieren dienen.Advantageous developments of the spacer according to the invention are disclosed in the subclaims, which also serve to improve the handling of the spacers during manufacture and assembly.

Einzelheiten der Erfindung sind in der Zeichnung schematisch und beispielsweise dargestellt. Es zeigen:

  • Fig. 1 einen Querschnitt durch ein breites Abstandhalter-Profil in seiner Anordnung zwischen zwei Glasscheiben,
  • Fig. 2 einen Querschnitt durch ein schmales Abstandhalter-Profil und
  • Fig. 3 u. 4 Querschnitte durch Abstandhalter-Profile mit unterschiedlich gewölbten Wänden.
Details of the invention are shown schematically and for example in the drawing. Show it:
  • 1 shows a cross section through a wide spacer profile in its arrangement between two glass panes,
  • Fig. 2 shows a cross section through a narrow spacer profile and
  • Fig. 3 u. 4 cross-sections through spacer profiles with differently curved walls.

Der Abstandhalter 1 ist bei sämtlichen Ausführungsbeispielen in einen geschlossenen Hohlprofilbereich 2 und in einen gabelförmigen Profilbereich 3 unterteilt, die sich beidseits einer Innenwand 6 erstrecken. Der geschlossene Hohlprofilbereich 2 wird durch den Hohlraum 4 begrenzende Wände gebildet, nämlich die Außenwand 5, die Innenwand 6, die beiden Schrägwände 7 und die beiden seitlichen Wandabschnitte 8. Der gabelförmige Profilbereich 3 wird durch die Innenwand 6 mit den darüber hinaus vorstehenden Schenkeln 9 der Seitenwände bestimmt.In all of the exemplary embodiments, the spacer 1 is subdivided into a closed hollow profile region 2 and into a fork-shaped profile region 3, which extend on both sides of an inner wall 6. The closed hollow profile area 2 is formed by walls delimiting the cavity 4, namely the outer wall 5, the inner wall 6, the two inclined walls 7 and the two lateral wall sections 8. The fork-shaped profile area 3 is formed by the inside wall 6 with the beyond protruding legs 9 of the side walls determined.

Die Breite a des geschlossenen Hohlprofilbereiches 2 ist kleiner, als die Breite b des gabelförmigen_Profilbereiches 3.The width a of the closed hollow profile area 2 is smaller than the width b of the fork-shaped_profile area 3.

Die seitlichen Wandabschnitte 8 weisen hohlkehlenförmige, nach innen zurückspringende und durchlaufende Nuten 10 auf, die zur Aufnahme von Dichtungsmitteln 16, insbesondere ButylprofilschnUren, bestimmt sind.The side wall sections 8 have grooves, which recess inward and pass through and are intended for receiving sealing means 16, in particular butyl profile cords.

Der Abstandhalter 1 ist beim AusfUhrungsbeispiel als Strangpreßhohlprofil aus Leichtmetall, insbesondere Aluminium, gestaltet. Es ist aber auch denkbar, die ähnliche Profilform durch Verformen von Metallbändern zu erhalten. Auch die Anwendung extrudierter Kunststoffprofile wird von der Erfindung nicht ausgeschlossen.In the exemplary embodiment, the spacer 1 is designed as an extruded hollow profile made of light metal, in particular aluminum. However, it is also conceivable to obtain the similar profile shape by deforming metal strips. The use of extruded plastic profiles is also not excluded from the invention.

In jedem Falle führt die erfindungsgemäße Gestaltung des Abstandhalters 1 dazu, daß nach dem Biegen des Profils nur die Außenflächen der Schenkel 9 zur Anlage an die Glasscheiben 15 gelangen, wohingegen die Wände 5,7,8 des geschlossenen Hohlprofilbereiches 2 wegen der geringeren Breite a im eingebauten Zustand in Distanz zu den Scheiben 15 liegen. Die Profilschnur 16 kann daher beim Anpressen der Scheibe 15 und auch beim Erwärmen sich nur nach außen hin verformen, indem die-beim Erwärmen pastös werdende Masse nach dem geringsten Widerstand hin wandert. In Richtung zur Scheibenmitte wird die Verformung des Dichtungsmittels 16 durch eine Barriere 17 verhindert. Da die Nut 10 außerdem in der neutralen Zone des Abstandhalters 1 liegt, wird der Biegevorgang nicht negativ beeinflußt, zugleich aber eine Erhöhung der Formgenauigkeit im gebogenen Zustand erreicht.In any case, the design of the spacer 1 leads to the fact that after the profile has been bent, only the outer surfaces of the legs 9 come into contact with the glass panes 15, whereas the walls 5, 7, 8 of the closed hollow profile region 2 because of the smaller width a in installed state at a distance from the disks 15. The profile cord 16 can therefore only deform outwardly when the disc 15 is pressed and also when heated, by the mass becoming pasty when heated migrating towards the slightest resistance. In the direction of the center of the pane, the deformation of the sealant 16 is prevented by a barrier 17. Since the groove 10 is also in the neutral zone of the spacer 1, the bending process is not adversely affected, but at the same time an increase in the accuracy of shape in the bent Condition reached.

Eine Vielzahl von Abstandhaltern 1 kann miteinander gestapelt werden, indem die Schenkel 9 den hohltrapezförmigen Teil 7 des benachbarten Profiles umgreifen. Die Stirnflächen 11 der Schenkel 9 sind hierbei mit Abschrägungen 12 versehen, die beim AusfUhrungsbeispiel der Figur 1 gleiche Winkellage wie die Schrägwände 7 aufweisen. Zufolge dieser Winkelgleichheit ist eine gute zentrierte AbstUtzung ohne Gefahr der Beschädigung beim Transport gewährleistet. Durch eine entsprechende Dimensionierung kann erreicht werden, daß die Außenwand 5 des einen Profiles beim Stapeln an der Innenwand 6 des benachbarten Profils zur Anlage kommt. Dies hat den Vorteil, daß eine Vielzahl solcher Abstandhalter in raumsparender Weise verpackt und versandt werden kann. Außerdem ist die Möglichkeit eröffnet, einen ganzen Stapel solcher Abstandhalter gemeinsam mit dem feuchtigkeitsaufnehmenden Material zu füllen, was zur erheblichen Beschleunigung der Produktion fUhrt.A large number of spacers 1 can be stacked together by the legs 9 engaging around the hollow trapezoidal part 7 of the adjacent profile. The end faces 11 of the legs 9 are provided with bevels 12 which, in the exemplary embodiment in FIG. 1, have the same angular position as the inclined walls 7. As a result of this angle equality, a good centered support is guaranteed without the risk of damage during transport. By appropriate dimensioning it can be achieved that the outer wall 5 of one profile comes to rest when stacking on the inner wall 6 of the adjacent profile. This has the advantage that a large number of such spacers can be packed and shipped in a space-saving manner. In addition, the possibility is opened to fill a whole stack of such spacers together with the moisture-absorbing material, which leads to a considerable acceleration in production.

Wie bei Abstandhaltern üblich, weist die Innenwand 6 mindestens eine durchlaufende Nut 18 auf, die zur Wandschwächung führt. In diesem Bereich der Wandschwächung sind Perforationen 19 oder sonstige Durchbrüche gebildet, welche eine Verbindung des Fensterinnenraumes mit dem Hohlraum 4 des Abstandhalters zwecks Feuchtigkeitsaufnahme gestattet.As is usual with spacers, the inner wall 6 has at least one continuous groove 18 which leads to the weakening of the wall. In this area of the wall weakening, perforations 19 or other openings are formed which allow the window interior to be connected to the cavity 4 of the spacer for the purpose of moisture absorption.

In jedem Falle empfiehlt es sich,.die Wandstärke der Außenwand 5 größer als diejenige der Innenwand 6 zu dimensionieren. Hierbei ist berücksichtigt, daß die Außenwand 5 beim Biegen einer erheblichen Zugspannung unterliegt. Eine Vergrößerung ihrer Wandstärke fuhrt dazu, daß Einrisse beim Biegen nicht auftreten können. Überdies ist in Figur 1 noch die Anordnung von im Querschnitt beispielsweise dreieckigen Stegen 14 an der Innenseite der Innenwand 6 gezeigt. Diese Stege 14 überbrücken die Toleranz zwischen den in den Hohlraum 4 einschiebbaren Verbindungsmitteln 20 und den Innenwandflächen. Durch teilweise Abflachung oder Deformationen dieser Stege 14 wird beim Eintreiben der Verbindungsmittel 20 in den Hohlraum 4 ein strammer Sitz herbeigeführt. Wird der Abstandhalter 1 aus einem StUck gebogen, dann ist nur ein Verbindungsmittel 20 im Stoßbereich vorzusehen. Bei mehrteiliger Zusammensetzung des Abstandhalters 1 ergeben sich entsprechend viele Stoßstellen.In any case, it is advisable to dimension the wall thickness of the outer wall 5 larger than that of the inner wall 6. It is taken into account that the outer wall 5 is subject to considerable tensile stress during bending. Increasing their wall thickness means that cracks cannot occur when bending. Furthermore, the arrangement of webs 14, for example triangular in cross section, on the inside of the inner wall 6 is shown in FIG. These webs 14 bridge the tolerance between the connecting means 20 that can be inserted into the cavity 4 and the inner wall surfaces. Due to the partial flattening or deformation of these webs 14, a tight fit is brought about when driving the connecting means 20 into the cavity 4. If the spacer 1 is bent from one piece, then only one connecting means 20 is to be provided in the joint area. With a multi-part composition of the spacer 1, there are a corresponding number of joints.

Beim AusfUhrungsbeispiel der Figur 2 ist ein wesentlich schmalerer Abstandhqlter 1 gezeigt, bei dem die Abschrägung 12 an den Stirnflächen 11 der Schenkel 9 nicht der Neigung der Schrägwände 7 angepaßt zu sein braucht.In the exemplary embodiment in FIG. 2, a significantly narrower spacer 1 is shown, in which the bevel 12 on the end faces 11 of the legs 9 need not be adapted to the inclination of the inclined walls 7.

Im Beispiel der Figur 3 ist gezeigt, daß die Innenwand 6 und die Außenwand 5 mehr oder weniger gewölbt ausgebildet sein können. Beim Beispiel der Figur 3 ist die Innenwand 6 in Richtung zum Hohlraum 4 konvex gestaltet, wohingegen die Außenwand 5 in ihren Randbereichen Wölbungen 22 aufweist, die in die Schrägwände 7 übergehen. Mit Hilfe solcher Wölbungen 22 kann unter Umständen eine Konstanz der Wanddicken herbeigeführt werden.In the example in FIG. 3 it is shown that the inner wall 6 and the outer wall 5 can be designed to be more or less curved. In the example of FIG. 3, the inner wall 6 is convex in the direction of the cavity 4, whereas the outer wall 5 has arches 22 in its edge regions which merge into the inclined walls 7. With the help of such curvatures 22 a constant wall thickness can be brought about under certain circumstances.

Beim Ausführungsbeispiel der Figur 4 ist die Innenwand 6 eben gestaltet, wohingegen die Außenwand 5 mehrere Wölbungen 23 aufweist. Anstelle der Abschrägungen 12 gemäß Figuren 1 und 2 ist beim Beispiel der Figur 4 die Stirnfläche 11 des einzelnen Schenkels 9 innenseitig mit einer Abrundung 13 versehen, die ebenfalls der zentrierten AbstUtzung der Schenkel 9 an den Schrägwänden 7 des benachbarten Profiles dienen.In the embodiment of Figure 4, the inner wall 6 is flat, whereas the outer wall 5 has a plurality of arches 23. Instead of the bevels 12 according to FIGS. 1 and 2, in the example of FIG. 4, the end face 11 of the individual leg 9 is provided on the inside with a rounded portion 13, which likewise serve to center the leg 9 on the inclined walls 7 of the adjacent profile.
