Description
Die Erfindung betrifft einen Linearveibinder aus Kunststoff für hohle Abstandhalterprofile von Mehrscheibenisoliergläsern, dessen länglicher Körper einen vollständig oder im wesentlichen vollständig U-förmigen Querschnitt für den Durchgang eines Molekularsiebs aufweist und in den Hohlraum des einen Abstandhalterprofils sowie den Hohlraum des anderen Abstandhakerprofils der beiden miteinander zu verbindenden Profilkörper einsteckbar ist und der eine mit Anschlagelementen versehene Oberfläche aufweist, welche beim Einstecken gegen die einander zugewandten Profilkörperstirnseiten stoßen, sowie mit lamellenförmigen Ausgleichsfedern zur Erzeugung eines festen Sitzes zwischen dem Körper und der Innenwand des Abstandhalterprofils versehen ist.The invention relates to a Linearveibinder made of plastic for hollow spacer profiles of multi-pane insulating glass, whose elongated body is a complete or im essentially completely U-shaped cross-section for the passage of a molecular sieve and in the cavity of a spacer profile and the cavity of the another Abstandhakerprofils the two profile body to be joined together can be inserted and having a provided with stop elements surface, which push when plugging against the facing profile body end faces, as well as with lamellar compensating springs to create a tight fit between the body and the inner wall of the spacer profile is provided.
Bekannte Linearverbinder dieser Art sind in den DE-GM 88 16 799 und 92 16 955 sowie in der EP-A-0 778 389 beschrieben. Sie entfalten im Hinblick auf den von derartigen Verbindern geforderten Zusammenhalt der miteinander verbundenen Abstandhalterprofile nach ihrem Einbau jedoch keine optimale Wirkung, da sich nicht selten der Verbindungsstoß an insbesondere aus Stahl bestehenden Profilkörpern zu einem Spalt öffnet, durch den das in den Hohlraum der Profilkörper befindliche Molekularsieb in den Scheibenzwischenraum austreten kann und diesen verschmutzt.Known linear connectors of this type are described in DE-GM 88 16 799 and 92 16 955 as well as in EP-A-0 778 389 described. They unfold with regard to the required of such connectors Cohesion of the interconnected spacer profiles after their installation, however no optimal effect, since not infrequently the connection joint, in particular made of steel existing profile bodies opens to a gap through which in the cavity of the Profilkörper molecular sieve can escape into the space between the panes and this dirty.
In diesem Zusammenhang ist darauf hinzuweisen, daß auch doppelläufige Geradverbinder zur Verbindung von aus zwei parallelen, durch eine Isolierung getrennten Profilsträngen gebildeten hohlen Abstandsprofilen oder Sprossenprofilen eines Mehrscheibenisolierglases bekannt sind, das wenigstens zwei parallele Glasscheiben aufweist, die an ihrem Umfangsrand durch das Abstandsprofil voneinander getrennt sind, wie dies die US-PS 5 603 582 beschreibt. In this context, it should be noted that even double-barreled straight connectors for Connection of two parallel, separated by an isolation profile strands formed hollow spacer profiles or rungs profiles of a multi-pane insulating glass are known, which has at least two parallel glass panes, which at its peripheral edge separated by the spacing profile, as described in US Pat. No. 5,603,582 describes.
Die wesentliche Voraussetzung für den Zusammenhalt der Abstandhalterprofile am Verbindungsstoß wird durch die Forderung beschrieben, daß der U-Profilkörper beim Einbau in den Hohlraum den miteinander zu verbindenden Abstandhalterprofile im wesentlichen nur elastisch und nicht plastisch verformt wird und dadurch seine Federeigenschaft beibehält, so daß die mit der Innenwandung der Abstandhalterprofile in Berühnmg tretenden Oberflächenteile des Linearverbinders eine Reibungskraft entfalten, die lange Zeit aufrecht erhalten bleibt, mindestens jedoch so lange, bis die entsprechende Isolierglasscheibe fertiggestellt, das heißt, der aus den betreffenden Abstandhalterprofilen hergestellte Rahmen zwischen die beiden Glasscheiben eingebaut und abgedichtet worden ist.The essential condition for the cohesion of the spacer profiles on Connecting joint is described by the requirement that the U-profile body during installation in the cavity to be interconnected spacer profiles substantially only elastic and not plastically deformed and thereby maintains its spring property, so that the passing with the inner wall of the spacer profiles in Berühnmg Surface parts of the linear connector unfold a frictional force, the long time upright is maintained, but at least until the corresponding insulating glass pane finished, that is, the frame produced from the respective spacer profiles installed and sealed between the two panes.
Die Aufgabe der Erfindung besteht deshalb darin, den Linearverbinder so zu verbessern, daß die an ihm bei seinem Einbau in den Hohlraum der Abstandhalterprofile bewirkten Verformungen nicht zu einer erheblichen Minderung der zwischen seiner Oberfläche und der ihm gegenüberliegenden Innenwandung der Abstandhalterprofile entwickelten Reibungskräfte führen. In diesem Zusammenhang soll die Verformung des Linearverbinders nicht plastischer, sondern elastischer Natur sein, das heißt, die Federeigenschaft seiner lamellenförmigen Ausgleichsfedern soll nach einem Einbau eine Zeit aufrecht erhalten bleiben. In diesem Zusammenhang soll ferner der Linearverbinder nach seinem Einbau in den Hohlraum der Abstandhalterprofile festsitzen, so daß sich der Verbindungsspalt zwischen den Körperstimseiten nicht öffnet.The object of the invention is therefore to improve the linear connector so that which caused him to be installed in the cavity of the spacer profiles Deformations do not cause a significant reduction in the surface between it and the opposite inner wall of the spacer profiles developed frictional forces to lead. In this context, the deformation of the linear connector is not plastic, but elastic nature, that is, the spring characteristic of its lamellar Balancing springs should be maintained for a period of time after installation. In this In addition, should the linear connector after its installation in the cavity of the Stuck spacer profiles, so that the connecting gap between the Body side does not open.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die lamellenförmigen Ausgleichsfedern, die von den Seitenflächen der beiden Schenkel des U-Profilkörpers nach außen ragen, durch dünne Stege miteinander verbunden sind und daß die beiden parallelen Schenkel des U-Profilkörpers auf ihrer Innenseite mit Verankerungsrippen versehen sind, die gegen den Boden des U-Profilkörpers abgestützt sind.This object is achieved in that the lamellar Balancing springs extending from the side surfaces of the two legs of the U-profile body protrude outward, are interconnected by thin webs and that the two parallel leg of the U-profile body on its inside with anchoring ribs are provided, which are supported against the bottom of the U-profile body.
Die Verbindung der lamellenförmigen Ausgleichsfedern durch dünne Stege hat den Vorteil, daß die Ausgleichsfedern beim Einbau des Linearverbinders in die hohlen Abstandsprofile so abgestützt werden, daß sie nicht kippen, sich also nicht bleibend verformen, wodurch die elastische Fedenmgswirkung und damit der Reibschluß zwischen U-Profilkörper und Abstandhalterprofil erhalten bleiben, was bedeutet, daß sich der Verbindungsstoß zwischen den miteinander verbundenen Abstandhalterprofilen jedenfalls solange nicht öffnet, bis das Abstandhalterprofil mit den Glasscheiben bei der Isolierung eines Mehrscheibenisolierglases fest verbunden worden ist. Auch danach bietet in aller Regel diese Konstruktion eine Sicherheit dafür, daß sich das Stoßspalt nicht öffnet und damit auch kein Molekularsieb in den Scheibenzwischenraum austreten kann. Desweiteren ist die Verwendung von Verstärkungsrippen zur Abstützung der Schenkel des U-Profilkörpers gegen dessen Boden vorteilhaft, weil diese Verstärkungsrippen Verformungen der Schenkel unter der Einwirkung von Biegekräften in Richtung zur Körperlängsachse vermeiden, so daß sogar eine dünnere Wandstärke der Schenkel und damit eine entsprechende Materialeinsparung ermöglicht wird. Dies wiederum führt zu einer Erhöhung der Elastizität der Schenkel unter der Einwirkung von Verformungskräften sowie einer Vergrößerung des Durchgangsquerschnitts für das Molekularsieb.The connection of the lamellar compensating springs by thin webs has the advantage that the compensation springs in the installation of the linear connector in the hollow spacer profiles so be supported so that they do not tilt, so do not deform permanently, causing the elastic Fedenmgswirkung and thus the frictional engagement between U-profile body and Spacer profile are maintained, which means that the joint between In any case, does not open the interconnected spacer profiles until the Spacer profile with the glass panes when insulating a multi-pane insulating glass has been firmly connected. Even then, as a rule, this construction offers one Assurance that the impact gap does not open and therefore no molecular sieve in the Disc space can escape. Furthermore, the use of Reinforcing ribs for supporting the legs of the U-profile body against the bottom advantageous because these reinforcing ribs deformations of the legs under the action Avoid bending forces in the direction of the body longitudinal axis, so that even a thinner Wall thickness of the legs and thus a corresponding material savings is possible. This in turn leads to an increase in the elasticity of the legs under the action of deformation forces and an increase in the passage cross section for the Molecular sieve.
In diesem Zusammenhang hat sich besonders bewährt, daß sich die Stege, die die lamellenförmigen Ausgleichsfedern, welche von den Seitenflächen der beiden Schenkel des U-Profilkörpers nach außen ragen, miteinander verbinden, parallel zur Längsachse des U-Profilkörpers erstrecken und darüber hinaus in einer Reihe fluchtend hintereinander liegen, wobei auch gleiche Abmessungen für diese Stege zweckmäßig sind. Darüber hinaus sollten sich vorteilhafterweise die Stege bis zu den Spitzen der lamellenartigen Ausgleichsfedern erstrecken und eine hautartige Konfiguration aufweisen, wodurch die elastischen Rückstellkräfte der Ausgleichsfedem beim Einschieben des Linearverbinders in den Hohlraum der Abstandhalterprofile verstärkt werden.In this context, it has proven particularly useful that the webs, the lamellar compensating springs, which from the side surfaces of the two legs of the U-profile body protrude outward, connect with each other, parallel to the longitudinal axis of the U-profile body extend and in addition in a row in alignment, whereby also the same dimensions are expedient for these webs. In addition, should Advantageously, the webs up to the tips of the lamellar balance springs extend and have a skin-like configuration, whereby the elastic Restoring forces of Ausgleichsfedem when inserting the linear connector in the cavity the spacer profiles are reinforced.
Es hat sich ferner als vorteilhaft erwiesen, die aufeinanderfolgenden Ausgleichsfedern durch mehrere parallele Stege miteinander zu verbinden und die Stege so zu bemessen, beziehungsweise zu formen, daß sie den beim Einschieben des Linearverbinders in den Hohlraum der Abstandhalterprofile auf die Ausgleichsfedern einwirkenden Biege- und Druckkräften entgegenwirken und ein Umkippen dieser Federn verhindern.It has also proved to be advantageous, the successive balancing springs through to connect several parallel webs together and to measure the webs so or to form that they when inserting the linear connector in the Cavity of the spacer profiles on the compensating springs acting bending and Counteract pressure forces and prevent tipping over of these springs.
Weitere vorteilhafte Ausgestaltungen, Anordnungen und Ausbildungen der Stege kennzeichnen sich dadurch, daß die Stege, bezogen auf die Breite der Ausgleichsfedern, versetzt angeordnet sein können oder auch gegen den Boden des U-Profilkörpers versetzt angeordnet sind, wobei sie dann darüber hinaus den lichten Raum zwischen den aufeinanderfolgenden Ausgleichsfedem nahezu vollständig ausfüllen können.Further advantageous embodiments, arrangements and configurations of the webs characterized in that the webs, based on the width of the compensating springs, can be arranged offset or offset against the bottom of the U-profile body are arranged, and then beyond the clear space between the can almost completely fill successive Ausgleichsfedem.
Was die beiden parallelen Schenkel des U-Profilkörpers anbelangt, die auf ihrer Innenseite mit Verstärkungsrippen versehen sind, welche gegen den Boden des U-Profilkörpers abgestützt sind, so hat es sich als vorteilhaft erwiesen, jeden Schenkel mit wenigstens zwei Verstärkungsrippen zu versehen, die symmetrisch zur Mittelachse des U-Profilkörpers angeordnet sind und zweckmäßigerweise mit dem Boden und der Innenwand des Schenkels ein gleichseitiges Dreieck bilden. As regards the two parallel legs of the U-profile body, which on its inside with Reinforcing ribs are provided which supported against the bottom of the U-profile body are, it has proved to be advantageous, each leg with at least two To provide reinforcing ribs, which are symmetrical to the central axis of the U-profile body are arranged and expediently with the bottom and the inner wall of the leg form an equilateral triangle.
Zur Optimierung der Abstützung der Schenkel sollten die Verstärkungsrippen bis etwa zur halben Höhe der Schenkel reichen, die Verstärkungsrippen gleich groß und über die Länge des U-Profilkörpers gleichmäßig verteilt sein. Zur Optimierung des Durchlaufs des Molekularsidebs durch den Hohlraum der Abstandhalterprofile beziehungsweise des Linearverbinders hat es sich als besonders vorteilhaft erwiesen, die Verstärkungsrippen mit abgeschrägten oder abgerundeten Vorder- und Rückseiten zu versehen, da auf diese Weise der Strömungswiderstand dieser Rippen für das Molekularsieb gering gehalten wird.To optimize the support of the legs, the reinforcing ribs should be up to about half the height of the legs are sufficient, the reinforcing ribs equal and over the length be distributed evenly over the U-profile body. To optimize the flow of the Molekularsidebs through the cavity of the spacer profiles or the Linear connector, it has proved to be particularly advantageous with the reinforcing ribs bevelled or rounded front and back sides, as in this way the flow resistance of these ribs is kept low for the molecular sieve.

Der in Fig. 1 gezeigte Linearverbinder ist ein U-Profilkörper 1 aus Kunststoff, hat also einen
im wesentlichen vollständig U-förmigen Querschnitt und dient zur Verbindung von hohlen
Abstandhalterprofilen von Mehrscheibenisoliergläsern. Zu diesem Zweck ist seine
Querschnittsform derjenigen der miteinander zu verbindenden Profilkörper angepaßt und wird
in deren Enden bis zu einem Anschlag 2 eingeführt. Der U-Profilkörper 1 weist zwei parallele
Schenkel 6 auf, die auf der Bodenplatte 12 des Profilkörpers stehen, wie aus Fig. 2 ersichtlich,
und durch Verstärkungsrippen 9 versteift sind. Von den Seitenflächen 11 der beiden Schenkel
6 ragen lamellenförmige Ausgleichsfedem 3 nach außen, die jeweils teilweise durch dünne
Stege 4 miteinander verbunden sind, welche sich parallel zur Längsachse A des U-Profilkörpers
erstrecken und, wie aus Fig. 4 ersichtlich, fluchtend hintereinander liegen. Beim
Einführen des Linearverbinders in die Abstandhakerprofile legen sich die Ausgleichsfedern 3
an die Innenwandung der Abstandhalterprofile elastisch an und erzeugen dadurch einen
Reilschluß, der verhindert, daß sich der Schließspalt an den Profilkörperstimseiten der
miteinander verbundenen Abstandhalterprofile, die in der Zeichnung nicht dargestellt sind,
später wieder öffnet. Die Stege 4 sind, bezogen auf die Breite der Ausgleichsfedern 3, wie
ebenfalls aus Fig. 4 ersichtlich, außermittig angeordnet, das heißt, gegen die Bodenplatte 12
des U-Profilkörpers 1 verschoben. Sie erstrecken sich bis etwa zu den Spitzen 5 der
lamellenartigen Ausgleichsfedern 3 und weisen eine hautartige Konfiguration auf, die die
elastische Rückstellkraft der Ausgleichsfedern beim Einschieben des Linearverbinders in den
Hohlraum der Abstandhalterprofile verstärkt. In jedem Fall sind die Stege so bemessen und
geformt, daß sie den beim Einschieben des Linearverbinders auf die Ausgleichsfedern
einwirkenden Biege- und Druckkräften entgegenwirken und ein Umkippen dieser Federn
verhindern.The linear connector shown in Fig. 1 is a U-profile body 1 made of plastic, so has a
essentially completely U-shaped cross section and serves for the connection of hollow
Spacer profiles of multi-pane insulating glass. For this purpose is his
Cross-sectional shape of those adapted to be joined together profile body and is

Das Einschieben des Linearverbinders erfolgt bis zu Anschlägen 2 auf den Seitenflächen 11
der beiden Schenkel 6 des U-Profilkörpers 1 und damit bis zur Verbindermitte. Das
Einschieben wird durch keilartige Elemente 7 an den beiden Enden des U-Profilkörpers
erleichtert sowie durch die Tatsache, daß die Ausgleichsfedem im Bereich dieser Enden
kürzer sind als im übrigen Bereich, in dem sie durch die Stege 4 miteinander verbunden sind.The insertion of the linear connector is up to stops 2 on the side surfaces 11th
the two legs 6 of the U-profile body 1 and thus to the connector center. The
Insertion is by wedge-
Im übrigen weist die Bodenplatte des U-Profilkörpers Öffnungen 8 auf, die jedoch in keinem
direkten Zusammenhang mit Anordnung und Gestaltung der Ausgleichsfedern stehen. In
jedem Fall ist die Querschnittsform des Linearverbinders an den Profilquerschnitt der
miteinander zu verbindenden Abstandhalterprofile angepaßt. Anordnung und Ausbildung der
Stege 4 sind in Anpassung an die jeweilige Profilform und Gestaltung der lamellenförmigen
Ausgleichsfedern 3 variabel, wobei auch die in der Zeichnung nicht dargestellte Möglichkeit
besteht, falls erforderlich, die aufeinanderfolgenden Ausgleichsfedern 3 durch mehrere
parallele Stege 4 miteinander zu verbinden.Moreover, the bottom plate of the U-profile
Beim Einbau des U-Profilkörpers in den Hohlraum der Abstandhalterprofile werden, da der
U-Profilkörper 1 gegenüber den Hohlraumabmessungen, bezogen auf die U-Profilbreite über
die Ausgleichsfedern 3, ein Übermaß aufweist, die Spitzen 5 der Ausgleichsfedern 3 gegen
die Einschubrichtung gedrückt, da die Stirnfläche des Abstandhalterprofils an den Spitzen 5
zunächst anstößt. Dieses Wegdrücken oder Nachhintendrücken der Ausgleichsfedern 3 fühlt
aber nur zu einer elastischen und nicht plastischen oder dauerhaften Verformung, da die
hautartigen Stege 4 eine zu starke Verformung der Ausgleichsfeder 3 verhindern, indem sie
selbst geringfügig federnd zusammengepreßt werden, um sich nach Überwindung des durch
die Stirnseite des Abstandhalterprofils gebotenen Einschubwiderstandes wieder etwas zu
entspannen und dabei die lamellenförmigen Ausgleichsfedern aufzurichten, so daß sie mit der
Innenwandung der Abstandhakerprofile in Reibschlußberührung verharren, wodurch der
angestrebte feste Sitz des Profilkörpers in den Abstandhalterprofilen sichergestellt wird und es
wenigstens so lange vermieden wird, daß sich der Stoßspalt der Abstandhalterprofile öffnet,
bis die Isolierglasscheibe fertiggestellt, d.h. der Rahmen, aus dem die miteinander
verbundenen Abstandhalterprofile bestehen, und die beiden auf diesen Rahmen aufgesetzten
Glasscheiben fest miteinander verbunden sind.When installing the U-profile body in the cavity of the spacer profiles, since the
U-profile body 1 with respect to the cavity dimensions, based on the U-profile width over
the compensating
In der Regel bleibt der Stoßspalt auch danach geschlossen, weil die Stege 4, die den lichten
Raum zwischen den Ausgleichsfeder 3 vollständig oder nahezu vollständig ausfüllen können,
die Reibschlußwirkung zwischen Linearverbinder und Abstandhalterprofil dauerhaft
unterstützen.In general, the impact gap remains closed even then, because the
Wie aus den Figuren 1 und 3 ersichtlich, ist jeder Schenkel 6 des U-Profilkörpers mit zwei
Verstärkungsrippen 9 versehen, die symmetrisch zur Mittelachse C des Körpers angeordnet
sind und mit dem Boden 12 des U-Profilkörpers sowie der Innenwand 10 seiner Schenkel 6
ein vorzugsweise gleichseitiges, rechteckiges Dreieck bilden, dessen konkav gebogene
Hypotenuse vorzugsweise bis etwa zur halben Höhe des Schenkels 6 reicht und das mit der
Innenwand 10 einen rechten Winkel einschließt.As can be seen from Figures 1 and 3, each leg 6 of the U-profile body with two
Provided reinforcing
Es versteht sich, daß mehr als zwei derartige Verstärkungsrippen an jedem Schenkel 6 des U-Profilkörpers angeordnet sein können, wobei die Vorder- und Rückseiten 13, 14 dieser Rippen zur Verringerung des Durchlaufwiderstandes für das Molekularsieb abgeschrägt bzw. abgerundet sein können, was in der Zeichnung nicht dargestellt ist.It is understood that more than two such reinforcing ribs on each leg. 6 the U-profile body can be arranged, wherein the front and rear sides 13, 14th these ribs to reduce the flow resistance for the molecular sieve be chamfered or rounded, which is not shown in the drawing.
Darüber hinaus besteht die Möglichkeit, an Stelle von mehreren nur eine einzige
Verstärkungsrippe 9 bei jedem Schenkel zu verwenden, die sich im wesentlichen über die
gesamte Länge des U-Profilkörpers erstreckt, um dadurch die Abstützung zu optimieren
und gleichzeitig den Durchflußwiderstand gegenüber einer Vielzahl von Einzelrippen,
welche, abgesehen von abgeschrägten oder abgerundeten Vorder- und Rückseiten ganz
allgemein auch aerodynamisch geformt sein können, weiter zu verringern.In addition, there is the possibility, in place of several only a single
Reinforcing
Derartige Verstärkungsrippen haben den Vorteil, daß die Schenkel 6 des U-Profilkörpers
beim Einbau dieses Körpers in die Abstandhalterprofile nicht zu stark nach innen
gedrückt werden und sich dabei bleibend verformen. Die Verstärkungsrippen 9 setzen
dieser Verformung einen Widerstand entgegen und unterstützen dadurch das elastische
Verhalten bzw. das Federungsvermögen des Linearverbinders in Querrichtung. Sie
bieten in diesem Zusammenhang den Vorteil, daß die Dicke der Schenkel 6 verringert
werden kann, ohne daß die Stabilität des U-Profilkörpers darunter leidet. Dies führt
wiederum zu einer Verbesserung des elastischen Verhaltens bzw. Federungsvermögens
in Querrichtung des Linearverbinders und damit zu einer Verbesserung seines festen
Sitzes innerhalb der hohlen Abstandprofilkörper. Eine Verringerung der Wanddicke der
Schenkel 6 hat darüber hinaus zur Folge, daß der Durchgangsquerschnitt des U-Profilkörpers
für das Molekularsieb sich vergrößert, wodurch die durch die
Verstärkungsrippen möglicherweise verursachten Strömungswiderstände nahezu
aufgewogen werden können.Such reinforcing ribs have the advantage that the legs 6 of the U-profile body
When installing this body in the spacer profiles not too strong inward
