Description

Die Erfindung betrifft einen Linearverbinder aus Kunststoff zur Verbindung von hohlen auf einer Biegemaschine zu biegenden Abstandhalterprofilen von Mehrscheibenisoliergläsern, mit einem flachen, länglichen Körper, von dem ein Längenstück in das eine Abstandhalterprofil und das andere Längenstück in das andere Abstandhalterprofil der beiden miteinander zu verbindenden Profile einsteckbar sind, und dessen Oberfläche mit Anschlagelementen versehen ist, welche beim Einstecken des Linearverbinders in den Hohlraum des Abstandhalterprofils gegen die einander zugewandten Profilstirnseiten stoßen, sowie mit Vorsprüngen zur Vergrößerung der Reibungskraft zwischen der Oberfläche des Linearverbinders und der Profilinnenwandoberfläche.The invention relates to a linear connector made of plastic for connecting hollow spacer profiles of multi-pane insulating glass to be bent on a bending machine, with a flat, elongated body, of which one length piece can be inserted into one spacer profile and the other length piece into the other spacer profile of the two profiles to be connected to one another are, and the surface of which is provided with abutment elements which, when the linear connector is inserted into the cavity of the spacer profile, abut against the facing end faces of the profile, and with projections for increasing the frictional force between the surface of the linear connector and the profile inner wall surface.

Die bekannten Linearverbinder dieser Art (DE-GM 90 16 592, DE-GM 91 10 972) weisen Gestaltungen auf, die im Hinblick auf den von derartigen Verbindern geforderten Zusammenhalt der miteinander zu verbindenden Abstandhalterprofile nach ihrem Einbau zu wünschen übrig lassen und die außerdem oftmals auch nicht so eingebaut werden können, daß nicht nur die gewünschte Einstecklänge in den Profilhohlraum eingehalten wird, sondern auch vermieden wird, daß der oftmals an den Stirnseiten der metallenen Profilkörper noch vorhandene Grat, der beim Abschneiden dieser Profile entsteht, sich beim Einstecken der Linearverbinder zwischen die Profilstirnseiten schiebt und dadurch ein bündiges Aufeinanderstoßen dieser Stirnseiten verhindert.The known linear connectors of this type (DE-GM 90 16 592, DE-GM 91 10 972) have designs which leave something to be desired after the installation in view of the cohesion of the spacer profiles to be connected, which are required by such connectors, and which also often also can not be installed in such a way that not only the desired insertion length is maintained in the profile cavity, but also is avoided that the burr that is often present on the end faces of the metal profile body, which arises when these profiles are cut off, gets between when the linear connector is inserted pushes the end faces of the profile, thereby preventing these end faces from colliding flush.

Die Aufgabe der Erfindung besteht deshalb darin, den Linearverbinder so weiterzubilden, daß die oben genannten Nachteile vermieden werden und insbesondere ein präziser Einbau in die Abstandhalterprofile ermöglicht wird, der mit Sicherheit ausschließt, daß sich an den Stirnseiten der metallenen Profile manchmal vorhandene, durch das Zuschneiden der Profile verursachte Metallrestteile zwischen die Verbinderoberfläche und die Oberfläche des Profilhohlraums schieben und dadurch das Profil in unerwünschter Weise verformen.The object of the invention is therefore to develop the linear connector so that the disadvantages mentioned above are avoided and in particular a more precise one Installation in the spacer profiles is made possible, which excludes with certainty that at the end faces of the metal profiles, existing metal parts caused by the cutting of the profiles slide between the connector surface and the surface of the profile cavity and thereby deform the profile in an undesirable manner.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Vorsprünge aus an den parallelen Schmalseiten des Körpers mit Abstand voneinander in Körperlängsrichtung und unter einem Winkel α zur Körperlängsachse B von etwa 30°-50° angeordneten, sich von innen nach außen zum Körperrand hin verjüngenden Lamellen bestehen, deren Ausrichtungswinkel an dem einen Längenstück sich von dem Ausrichtungswinkel an dem anderen Längenstück um etwa 90° unterscheidet und deren Spitzen beim Einstecken in den Profilhohlraum von der Profilwandung elastisch verbiegbar sind, wobei die Spitzen der einander zugewandten Lamellen an den Enden der beiden Längenstücke in der Mitte des Körpers als Anschlagelemente dienen und zwischen sich einen Spalt bilden, und daß sich auf der Oberfläche des Körpers im Bereich der Anschlagelemente Schneidgratbremsen in Form von einander zugewandten Auflaufschrägen befinden, die sich aus der Oberfläche des Körpers erheben und zwischen einen sich quer zur Körperlängsachse erstreckenden Spalt bilden.This object is achieved in that the projections are arranged on the parallel narrow sides of the body at a distance from one another in the body longitudinal direction and at an angle α to the body longitudinal axis B of about 30 ° -50 °, tapering from the inside outwards towards the body edge , whose alignment angle on one length piece differs from the alignment angle on the other length piece by about 90 ° and whose tips are elastically bendable when inserted into the profile cavity from the profile wall, the tips of the mutually facing slats at the ends of the two length pieces in the Serve center of the body as stop elements and form a gap between them, and that on the surface of the body in the area of the stop elements cutting edge brakes are in the form of mutually facing run-up slopes, which rise from the surface of the body and between one another form gap extending to the body longitudinal axis.

Durch die Ausbildung besonders geformter Lamellen in Verbindung mit lamellenförmigen Anschlagelementen und einer im Bereich dieser Anschlagelemente angeordneten Schneidgratbremse, die mögliche Metallreste an den Profilstirnseiten einebnet bzw. in dem von ihr gebildeten Spalt verschwinden läßt, werden die Einbaueigenschaften und auch die Standfestigkeit eines solchen Linearverbinders insbesondere für Abstandhalterprofile, die aufeiner Biegemaschine gebogen werden, erheblich verbessert.Due to the formation of specially shaped lamellae in conjunction with lamellar stop elements and a cutting edge brake arranged in the area of these stop elements, which levels out possible metal residues on the end faces of the profile or makes them disappear in the gap formed by them, the installation properties and also the stability of such a linear connector are particularly suitable for Spacer profiles that are bent on a bending machine have been significantly improved.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung entspricht der Abstand der einander zugewandten Spitzen der die Anschlagelemente bildenden Lamellen etwa der Spaltbreite der Schneidgratbremse, wobei sich hier Werte zwischen 0,5 und 1,5 mm besonders bewährt haben.According to an advantageous embodiment of the invention, the distance between the mutually facing tips of the plates forming the stop elements corresponds approximately to the gap width of the cutting edge brake, values between 0.5 and 1.5 mm having proven particularly useful here.

Um den Lamellen, die zu der jeweiligen Einschubrichtung geneigt sind und sich zu ihrer Spitze hin konisch verjüngen, einen Übergang in den Körper zu geben, der sowohl den Festigkeitsanforderungen an den Körper in seiner Gesamtheit als auch der verlangten Elastizität der Lamellen entspricht, hat es sich bewährt, die hinteren Enden der Lamellen durch einen Radius in den Körper des Linearverbinders übergehen zu lassen.In order to give the lamellae, which are inclined to the respective insertion direction and taper conically towards their tip, a transition into the body that meets the strength requirements for the body as a whole as well as the required Corresponds to the elasticity of the lamellae, it has proven useful to have the rear ends of the lamellae pass into the body of the linear connector by means of a radius.

Desweiteren sind die Spitzen der gegeneinander gerichteten Lamellen, die die Anschlagelemente bilden, zweckmäßigerweise so ausgebildet, daß die Lamellen im Bereich ihrer vorderen Enden aufeinander zu gerichtete Teile aufweisen, die sich annähernd parallel zur Körperlängsachse erstrecken, da auf diese Weise gewährleistet ist, daß die Anschlagelemente das jeweils von der Gegenseite aufgeschobene Profil des Linearverbinders an der gewüschten Stelle, nämlich in der Mitte des Körpers, stoppen.Furthermore, the tips of the mutually directed slats, which form the stop elements, are expediently designed such that the slats in the region of their front ends have parts which are directed towards one another and extend approximately parallel to the longitudinal axis of the body, since this ensures that the stop elements stop the profile of the linear connector pushed on from the opposite side at the desired location, namely in the middle of the body.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind den Unteransprüchen zu entnehmen.Further advantageous embodiments of the invention can be found in the subclaims.

Die Erfindung wird nachfolgend anhand des in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.The invention is explained in more detail below with reference to the embodiment shown in the drawing.

Der in den Zeichnungsfiguren 1 - 4 dargestellte Linearverbinder besteht aus Kunststoff und dient zur Verbindung von hohlen auf einer Biegemaschine zu biegenden, nicht dargestellten Abstandhalterprofilen von Mehrscheibenisoliergläsern. Er weist zu diesem Zweck einen flachen, länglichen Körper 1 mit einem Längenstück 6 auf, das in das eine Abstandhalterprofil einsteckbar ist und mit einem anderen Längenstück 7, das in das andere Abstandhalterprofil zweier miteinander zu verbindender Profile eingesteckt wird. Beide Läugenstücke 6 und 7 sind um die Mittelachse F des Körpers 1 symmetrisch aufgebaut, wie im folgenden noch erläutert wird.The linear connector shown in the drawing figures 1 - 4 is made of plastic and is used to connect hollow spacer profiles, not shown, of multi-pane insulating glass to be bent on a bending machine. For this purpose, it has a flat, elongated body 1 with a length 6 which can be inserted into one spacer profile and with another length 7 which is inserted into the other spacer profile of two profiles to be connected to one another. Both lye pieces 6 and 7 are constructed symmetrically about the central axis F of the body 1, as will be explained in the following.

Der Körper 1 ist an seinen parallelen Schmalseiten 3, 4 mit mit Abstand voneinander in Körperlängsrichtung und unter einem Winkel α zur Körperlängsachse B von etwa 30°-50° geneigten Lamellen 2a, 2b versehen, die sich von innen nach außen zum Körperrand hin verjüngen und deren Ausrichtungswinkel im Hinblick auf den oben genannten symmetrischen Aufbau der beiden Längenstücke an dem einen Längenstück 6 sich von dem Ausrichtungswinkel an dem anderen Längenstück 7 um etwa 90° unterscheidet, so daß die Lamellen jeweils der Einschubrichtung in das Profil entgegegensetzt gerichtet sind.The body 1 is on its parallel narrow sides 3, 4 at a distance from one another in the body longitudinal direction and at an angle α to the body longitudinal axis B of approximately Provided 30 ° -50 ° inclined slats 2a, 2b, which taper from the inside to the outside towards the body edge and whose alignment angle with respect to the above-mentioned symmetrical structure of the two length pieces on one length piece 6 differs from the orientation angle on the other length piece 7 differs by about 90 °, so that the slats are directed opposite to the direction of insertion into the profile.

Die Lamellen 2a, 2b sind mit Spitzen 8 versehen, die beim Einstecken in den Profilhohlraum von der Profilwandung elastisch verbogen werden, um auf diese Weise zwischen der Profilwandung und dem Linearverbinder einen Reibschluß herzustellen. Die an den Enden der beiden Langenstücke 6, 7 in der Mitte des Körpers 1 angeordneten Lamellen 2c, 2d sind mit einander zugewandten Spitzen 23, 24 ausgestattet, die als Anschlagelemente für die Stirnseiten der auf die Längenstücke 6 und 7 des Linearverbinders aufzuschiebenden Abstandprofile dienen, die zwischen sich einen durch ihren Abstand D verursachten Spalt 11 bilden, der sich beim Aufschieben der Abstandhalterprofile auf die Längenstücke geringfügig verkleinert und im vorliegenden Fall etwa 1 mm beträgt.The lamellae 2a, 2b are provided with tips 8 which, when inserted into the profile cavity, are elastically bent by the profile wall in order in this way to produce a frictional connection between the profile wall and the linear connector. The lamellae 2c, 2d arranged at the ends of the two long pieces 6, 7 in the middle of the body 1 are equipped with mutually facing tips 23, 24, which serve as stop elements for the end faces of the spacer profiles to be pushed onto the long pieces 6 and 7 of the linear connector, which form between them a gap 11 caused by their distance D, which is slightly reduced when the spacer profiles are pushed onto the length pieces and is about 1 mm in the present case.

Die Spitzen 23, 24 der Lamellen 2c, 2d befinden sich an aufeinander zu gerichteten Teilen 10a, 10b der Lamellen, die sich annähernd parallel zur Körperlängsachse B erstrecken und die Anschlagkräfte des aufgeschobenen Abstandhalterprofils in die betreffende Lamelle so einleiten, daß letztere nicht oder jedenfalls nicht wesentlich ausgebogen wird.The tips 23, 24 of the lamellae 2c, 2d are located on parts 10a, 10b of the lamellae which are directed towards one another and extend approximately parallel to the longitudinal axis B of the body and introduce the stop forces of the pushed-on spacer profile into the lamella in question in such a way that the latter does not, or at least not is significantly bent out.

Auf der Oberseite 13 des Körpers 1 befinden sich im Bereich der Anschlagelemente Schneidgratbremsen 5 in Form von paarweise einander zugewandten Auflaufschrägen 14, die sich aus dieser Oberfläche unter einem Winkel von etwa 6° erheben und zwischen sich einen Spalt 22 der Breite E bilden. Diese Schneidgratbremsen haben den Zweck, die vorderen Randkanten der auf den Linearverbinder aufgeschobenen Profilstirnseiten auf sie auflaufen zu lassen und dabei einen möglicherweise an diesen Stirnseiten vorhandenen Gratrest abzustreifen und diesen in dem Spalt 22 zu versenken, so daß er weder das Aufeinanderstoßen der Profilstirnseiten behindert, noch eine Aufweitung des Profils bewirken kann, da auf diese Weise dieses metallene Gratmaterial gewissermaßen in das Kunststoffmaterial des Linearverbinders eingebettet wird.On the top 13 of the body 1 there are cutting burr brakes 5 in the area of the stop elements in the form of paired bevels 14 which rise from this surface at an angle of approximately 6 ° and form a gap 22 of width E between them. The purpose of these cutting edge brakes is to let the front edge of the profile end faces pushed onto the linear connector run onto them and to scrape off any burr residue that may be present on these end faces and to sink it into the gap 22 so that it does not hinder the abutting of the profile end faces, nor can cause the profile to widen, since in this way this metallic burr material is to a certain extent embedded in the plastic material of the linear connector.

Die Spaltbreite E der Schneidgratbremsen 5 entspricht etwa dem Abstand D der aufeinander zu gewandten Spitzen 23, 24 der die Anschlagelemente bildenden Lamellen 2c, 2d.The gap width E of the cutting edge brakes 5 corresponds approximately to the distance D between the tips 23, 24 of the disks 2c, 2d forming the stop elements.

Die Oberseite 13 und die Unterseite 15 des Körpers 1 sind mit parallelen Längsnuten 16, 17 bzw. 18, 19 versehen, die eine Querschnittsverringerung des Körpers 1 in diesen Bereichen und damit eine Materialeinsparung mit sich bringen, jedoch auch eine längsrippenartige Struktur bilden, welche den Materialschwund des Körpers beim Spritzgießen verringert und damit seine Dimensionsstabilität insbesondere quer zur Längsachse B verbessert. Die elastischen Lamellen tun ein übriges, um Dimensionsschwankungen der Profilhohlräume auszugleichen und damit einen festen Sitz des Linearverbinders in den Hohlräumen sicherzustellen. Zu diesem Zweck sind die Lamellen 2a, 2b, 2c, 2d an ihren hinteren Enden 9 durch einen Radius mit dem Körper 1 verbunden und weisen einen Querschnitt 21 auf, der mit dem Querschnitt des Randbereiches der miteinander zu verbindenden Hohlprofile weitgehend übereinstimmt. Darüber hinaus erweitert sich der jeweils von zwei aufeinanderfolgenden Lamellen 2a₁, 2a₂ und 2b₁, 2b₂ eingeschlossene Raum C in Richtung der Spitzen 8, 10 der Lamellen konisch, so daß die Lamellen auch dann nicht abbrechen können, wenn der Linearverbinder in die Profilhohlräume eingeschlagen wird.The upper side 13 and the lower side 15 of the body 1 are provided with parallel longitudinal grooves 16, 17 and 18, 19, respectively, which reduce the cross-section of the body 1 in these areas and thus save material, but also form a longitudinal rib-like structure which forms the Material shrinkage of the body during injection molding is reduced and thus its dimensional stability is improved, in particular transverse to the longitudinal axis B. The elastic slats do the rest to compensate for dimensional fluctuations in the profile cavities and thus ensure that the linear connector is firmly seated in the cavities. For this purpose, the fins 2a, 2b, 2c, 2d are connected at their rear ends 9 to the body 1 by a radius and have a cross section 21 which largely corresponds to the cross section of the edge region of the hollow profiles to be connected to one another. In addition, each of two successive slats 2a₁, 2a₂ and 2b₁, 2b₂ enclosed space C tapered in the direction of the tips 8, 10 of the slats, so that the slats can not break off even when the linear connector is driven into the profile cavities.

Der eingeschlagene Linearverbinder kann zusätzlich an den Längenstücken 6, 7 mit den Abstandhalterprofilen mechanisch verbunden werden, indem das Material der Profile in in der Oberfläche des Körpers 1 ausgebildete Vertiefungen 20 mittels einer Stanz-oder Preßvorrichtung hineinverformt wird. Diese lochartigen Vertiefungen befinden sich bei der dargestellten Ausführungsform, wie aus den Figuren 1 und 3 ersichtlich, zwischen den Längsnuten 16, 17; 18, 19 beidseitig der Schneidgratbremsen 15 bzw. Anschlagelemente.The inserted linear connector can additionally be mechanically connected to the spacer profiles on the lengths 6, 7 by the material of the profiles being deformed into depressions 20 formed in the surface of the body 1 by means of a punching or pressing device. These hole-like depressions are in the embodiment shown, as can be seen from Figures 1 and 3, between the longitudinal grooves 16, 17; 18, 19 on both sides of the cutting edge brakes 15 or stop elements.
