Abstract

The connector (1) has leaves (27) which are elastically deformable and have a bent or angled or hooked shaped plane cross section. Each leaf projects at right angles to the longitudinal axis (B) of the connector body (9,10) at the rear end of its section where it is attached to a shallow long side (3) of the connector body. The other end of the leaf has a hook or point (41), one side face of which is approximately parallel to the longitudinal axis of the body and another side face is approximately perpendicular to that axis. The connector is inserted into the hollow spacer bodies in the correct position and held there by the pressure of the leaves against the inside of the spacer bodies.

Description

Die Erfindung betrifft einen Linearverbinder aus Kunststoff für hohle Abstandhalterprofile von Mehrscheibenisoliergläsern gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a linear connector made of plastic for hollow spacer profiles of multi-pane insulating glass according to the preamble of claim 1.

Die bekannten Linearverbinder der genannten 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 oftmals keine optimalen Wirkungen entfalten, da die flachen, länglichen Körper, von denen ein Längenstück in dem Hohlraum des einen Abstandhalterprofils und das andere Längenstück in den Hohlraum des anderen Abstandhalterprofils der beiden miteinander zu verbindenden Profilkörper einsteckbar sind, nicht in jedem Fall einen rutschfesten Sitz sicherstellen, der verhindert, daß die Oberflächen der Längenstücke auf den Oberflächen der Profilhohlräume nach dem Einbau unter den üblichen thermischen und Zugbeanspruchungen Gleitbewegungen ausführen und dadurch die Verbindungsstelle der Abstandhalterprofilkörper nicht so stabil halten, wie gefordert wird, um derartigen Isolierglasscheiben eine lange Lebensdauer zu garantieren.The known linear connectors of the type mentioned (DE-GM 90 16 592, DE-GM 91 10 972) have designs which, in view of the cohesion of the spacer profiles to be connected, which are required by such connectors, often do not have optimal effects after their installation, since the flat, elongated bodies, of which one length piece in the cavity of one spacer profile and the other length piece can be inserted into the cavity of the other spacer profile of the two profile bodies to be connected, do not in any case ensure a non-slip fit which prevents the surfaces perform the sliding movements on the surfaces of the profile cavities after installation under the usual thermal and tensile stresses and thereby do not keep the connection point of the spacer profile bodies as stable as is required in order to guarantee such insulating glass panes a long service life.

Die Aufgabe der Erfindung besteht deshalb darin, den Linearverbinder der genannten Art so weiterzubilden, daß er bei ausreichender Steifigkeit und Abriebfestigkeit des Verbindermaterials den gewünschten festen Sitz aufweist und dabei im Verbindungsbereich, d.h. in Körpermitte des Linearverbinders, beim Aufschieben der Abstandhalterprofile eine Anschlagwirkung entfaltet, die ein Durchschieben bzw. ein zu weites Hineinschieben des Linearverbinders in den Hohlraum der Abstandhalterprofile verhindert.The object of the invention is therefore to further develop the linear connector of the type mentioned so that it has the desired firm fit with sufficient rigidity and abrasion resistance of the connector material and, in the connection area, that is to say in the center of the body of the linear connector, unfolds a stop action when the spacer profiles are slid on, which prevents the linear connector from being pushed or pushed too far into the cavity of the spacer profiles.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Lamellen elastisch verformbar sind und einen gebogenen oder abgewinkelten, krallenförmigen Querschnitt aufweisen, derart, daß sie mit ihrem hinteren Ende rechtwinklig oder nahezu rechtwinklig zur Körperlängsachse aus der Oberfläche der beiden Schmalseiten des Linearverbinderkörpers austreten und an ihrem vorderen Ende eine Spitze oder Kante besitzen, welche von einer ersten Fläche parallel oder nahezu parallel zur Korperlängsachse und einer zweiten Flache senkrecht oder nahezu senkrecht zur Körperlängsachse gebildet wird.This object is achieved in that the lamellae are elastically deformable and have a curved or angled, claw-shaped cross section such that they emerge from the surface of the two narrow sides of the linear connector body with their rear end at right angles or almost at right angles to the longitudinal axis of the body and at their front End have a point or edge, which is formed by a first surface parallel or almost parallel to the body longitudinal axis and a second surface perpendicular or almost perpendicular to the body longitudinal axis.

Die für den vorgesehenen Verbindungszweck erforderliche Reibschlüssigkeit des aus Kunststoff bestehenden Verbinders, der mit einem rinnenförmigen, insbesondere U-förmigen Querschnitt für den Durchlauf des Molekularsiebs versehen ist, wird demnach durch eine besondere Ausgestaltung der Lamellen an den Schmalseiten des Linearverbinderkörpers sichergestellt, die mit Anschlagelementen, ebenfalls in Form elastischer Lamellen kombiniert sind, so daß das in den Hohlraum des Abstandhalterprofils eingeschobene Längenstück des Linearverbinderkörpers eine definierte Lage erhält und in dieser Lage auch festgehalten wird.The required frictional connection of the connector made of plastic, which is provided with a channel-shaped, in particular U-shaped cross-section for the passage of the molecular sieve, is therefore ensured by a special configuration of the lamellae on the narrow sides of the linear connector body, which with stop elements, are also combined in the form of elastic slats, so that the length of the linear connector body inserted into the cavity of the spacer profile is given a defined position and is also held in this position.

Die Lamellen auf den Schmalseiten des Linearverbinderkörpers sind, gemäß einer vorteilhaften Ausgestaltung des Erfindungsvorschlags, so ausgebildet, daß die erste Fläche an ihrem unteren Ende in eine gebogene Fläche übergeht, die senkrecht oder nahezu senkrecht auf die Oberfläche der Schmalseite stößt, und daß die zweite Fläche an ihrem hinteren, der Spitze oder Kante abgewandten Ende ebenfalls in eine gebogene Fläche übergeht, die gleichfalls senkrecht oder nahezu senkrecht auf die Oberfläche der Schmalseite stößt. Dabei können die beiden gebogenen Flachen den gleichen Krümmungsradius aufweisen, was bedeutet, daß sie parallel zueinander verlaufen.The lamellae on the narrow sides of the linear connector body are, according to an advantageous embodiment of the invention, designed so that the first surface at its lower end merges into a curved surface that abuts the surface of the narrow side perpendicularly or almost perpendicularly, and that the second surface at its rear end, facing away from the tip or edge, also merges into a curved surface which also abuts the surface of the narrow side perpendicularly or almost perpendicularly. The two curved surfaces can have the same radius of curvature, which means that they run parallel to one another.

Anstelle von gebogenen Flächen, die die Ober- und Unterseiten bzw. Vorder- und Hinterseiten der Lamellen begrenzen, hat es sich auch bewährt, die Konstruktion so weiterzubilden, daß die erste Fläche an ihrem unteren Ende in eine ebene Fläche übergeht, die in einem Winkeln α zur Körperlängsachse B geneigt ist und vor Erreichen der Oberfläche der Schmalseiten des Linearverbinderkörpers senkrecht oder nahezu senkrecht zu dieser Oberfläche abknickt und dadurch in eine senkrecht oder nahezu senkrecht verlaufende, gerade Fläche übergeht, und daß die zweite Fläche an ihrem hinteren, der Spitze oder Kante abgewandten Ende in eine gerade und unter einem Winkel β zur Körperlängsachse B und schräg zur Oberfläche der Schmalseiten verlaufende Fläche übergeht, die vor Erreichen der Oberfläche in eine senkrecht oder nahezu senkrecht zu dieser Oberfläche verlaufende, gerade Flache übergeht. In diesem Fall ist also die Lamelle nicht gebogen sondern geknickt ausgeführt, wobei die beiden Winkel α und β auch gleich groß sein können. Zur Erzielung eines optimalen Anpreßdruckes der Lamellen an der Oberfläche der Hohlprofilwandung hat es sich bewährt, das untere Ende der ersten Fläche in Höhe des Auftreffpunktes der gekrümmten Fläche bzw. der geraden Fläche auf der Oberfläche der Schmalseiten des Linearverbinderkörpers anzuordnen.Instead of curved surfaces which delimit the top and bottom sides or front and rear sides of the slats, it has also proven useful to further develop the construction in such a way that the first surface at its lower end merges into a flat surface which is at an angle α is inclined to the longitudinal axis B of the body and, before reaching the surface of the narrow sides of the linear connector body, kinks perpendicularly or almost perpendicularly to this surface and thereby merges into a perpendicular or nearly perpendicular, straight surface, and that the second surface at its rear, the tip or edge opposite end merges into a straight and at an angle β to the body longitudinal axis B and obliquely to the surface of the narrow sides, which before reaching the surface in a perpendicular or almost perpendicular to this surface, flat surface passes. In this case, the lamella is not curved but kinked, and the two angles α and β can also be the same size. In order to achieve an optimal contact pressure of the lamellae on the surface of the hollow profile wall, it has proven useful to arrange the lower end of the first surface at the point of impact of the curved surface or the straight surface on the surface of the narrow sides of the linear connector body.

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

Die in diesem Zusammenhang verwendete Bezeichnung "Querschnitt" bedeutet einen Schnitt durch eine Lamelle in der Ebene der Linearverbinderkörperlängsachse B, die in einige Zeichnungsfiguren eingezeichnet ist, in denen im übrigen entsprechende Teile mit demselben Bezugszeichen versehen worden sind.The term "cross-section" used in this context means a section through a lamella in the plane of the longitudinal axis B of the linear connector body, which is shown in some drawing figures, in which corresponding parts are otherwise provided with the same reference numerals.

Bei jeder dieser Ausführungsformen besteht der Linearverbinder aus Kunststoff und ist zur Verbindung von hohlen, aus Metall oder Kunststoff oder einem anderen geeigneten Material bestehenden Abstandhalterprofilen von Mehrscheibenisoliergläsern vorgesehen. Er weist hierzu einen flachen, länglichen Körper 1 auf, von dem das eine Längenstück 9 in den Hohlraum des einen, nicht dargestellten Abstandhalterprofils und das andere Längenstück 10 in den Hohlraum des anderen, ebenfalls nicht dargestellten Abstandhalterprofils der beiden miteinander zu verbindenden Profilkörper einsteckbar sind. Bei den dargestellten Ausführungsformen weist der Linearverbinderkörper 1 einen U-förmigen Querschnitt für den Durchlauf des Molekurlarsiebs auf und ist in der Körpermitte C auf seinen beiden Schmalseiten 3, 4 durch nach außen gerichtete, höckerförmige Verstärkungselemente 5, 6 radial verstärkt, denen wenigstens je ein Auschlagelement in Form einer elastischen, zur Körpermitte C geneigten Lamelle 7, 8 gegenüberliegt, die beim Einschieben des Linearverbinderkörpers 1 in den Hohlraum des Abstandhalterprofils, wenn sie in Einschubrichtung vor der Körpermitte C liegt, von der Abstandhalterprofilstirnseite gegen das Verstärkungselement 5, 6 niederdrückbar und dabei plastisch verformbar ist, und sofern sie in Einschubrichtung hinter der Körpermitte C liegt, einen Einschubanschlag für die Abstandhalterprofilstirnseite bildet. Einschubanschlag bedeutet in diesem Zusammenhang, daß der Linearverbinderkörper beim Einschieben nicht über diesen Anschlag hinaus geschoben und damit zu weit eingeschoben werden kann.In each of these embodiments, the linear connector is made of plastic and is provided for connecting hollow spacer profiles of multi-pane insulating glass, which are made of metal or plastic or another suitable material. For this purpose, it has a flat, elongated body 1, of which one length piece 9 into the cavity of one spacer profile, not shown, and the other length piece 10 into the cavity of the other spacer profile, also not shown two profile bodies to be connected can be inserted. In the illustrated embodiments, the linear connector body 1 has a U-shaped cross section for the passage of the molecular sieve and is radially reinforced in the middle C of the body on its two narrow sides 3, 4 by outwardly directed, hump-shaped reinforcing elements 5, 6, each of which has at least one deflection element in the form of an elastic lamella 7, 8 inclined towards the center of the body C, which when the linear connector body 1 is inserted into the cavity of the spacer profile, if it lies in the direction of insertion in front of the center of the body C, can be pressed against the reinforcing element 5, 6 by the spacer profile front side and thereby plastically is deformable, and insofar as it lies behind the center of the body C in the direction of insertion, forms an insertion stop for the front face of the spacer profile. Slide-in stop means in this context that the linear connector body cannot be pushed beyond this stop when it is pushed in and can therefore be pushed in too far.

Wie aus den in den Figuren 1 und 2 dargestellten beiden Ausführungsformen ersichtlich, sind die parallelen Schmalseiten 3, 4 des Verbinderkörpers mit Lamellen 27 der in Fig. 3 dargestellten Art ausgestattet, wobei diese Art auch durch die in Fig. 4 gezeigte Ausgestaltung einer Lamelle 28 ersetzt werden kann.As can be seen from the two embodiments shown in FIGS. 1 and 2, the parallel narrow sides 3, 4 of the connector body are equipped with lamellae 27 of the type shown in FIG. 3, this type also due to the configuration of a lamella 28 shown in FIG. 4 can be replaced.

Diese Lamellen 27, 28 sind in Richtung der Verbindungskörperlängsachse B mit Abstand voneinander und hintereinander angeordnet und jeweils zur Körperlängenmitte hin ausgerichtet. Das bedeutet, die in den Figuren 1a und 1c sowie 2a und 2c dargestellten Lamellen in der oberen Hälfte des Verbinderkörpers 1 weisen in Richtung zur Körpermitte C hin, also nach unten und die in der unteren Hälfte des Verbinderkörpers befindlichen Lamellen 27 weisen nach oben, ebenfalls in Richtung zur Körperlängenmitte C. Zu diesem Zweck weisen die elastischen Lamellen 27, 28 einen gebogenen oder abgewinkelten Querschnitt auf, derart, daß sie mit ihrem hinteren Ende 29 rechtwinklig oder nahezu rechtwinklig zur Körperlängsachse B aus der Oberfläche der beiden Schmalseiten 3, 4 austreten und an ihrem vorderen Ende 30 eine Spitze oder Kante 41 besitzen, welche von einer ersten Fläche 31 parallel oder nahezu parallel zur Körperlängsachse B und einer zweiten Fläche 32 senkrecht oder nahezu senkrecht zur Körperlängsachse B gebildet wird.These lamellae 27, 28 are arranged at a distance from one another and one behind the other in the direction of the longitudinal axis B of the connecting body, and are each oriented toward the center of the body length. That means that the lamellae shown in FIGS. 1a and 1c as well as 2a and 2c in the upper half of the connector body 1 point towards the center of the body C, i.e. downwards and the lamellae 27 in the lower half of the connector body also point upwards towards the middle of the body length C. For this purpose, the elastic lamellae 27, 28 have a curved or angled cross-section such that they emerge from the surface of the two narrow sides 3, 4 with their rear end 29 at right angles or almost at right angles to the longitudinal axis B of the body have at their front end 30 a point or edge 41 which is formed by a first surface 31 parallel or almost parallel to the body longitudinal axis B and a second surface 32 perpendicular or almost perpendicular to the body longitudinal axis B.

Die erste Fläche 31 geht, wie aus Fig. 4 ersichtlich, an ihrem unteren Ende 39 in eine gebogene Fläche 33 über, die senkrecht oder nahezu senkrecht auf die Oberfläche der Schmalseiten 3, 4 stößt, von denen nur eine in der Zeichnung zum Teil dargestellt ist, deren Lage jedoch deutlicher aus Fig. 1a entnommen werden kann. Die zweite Fläche 32 geht an ihren hinteren, der Spitze oder Kante 41 abgewandten Ende 42 in eine gebogene Fläche 34 über, die ebenfalls senkrecht oder nahezu senkrecht auf die Oberfläche der Schmalseite 3, 4 stößt.4, at its lower end 39, the first surface 31 merges into a curved surface 33 which abuts the surface of the narrow sides 3, 4 perpendicularly or almost perpendicularly, only one of which is shown in part in the drawing is, the location of which can be seen more clearly from Fig. 1a. The second surface 32 goes into a curved surface 34 at its rear end 42 facing away from the tip or edge 41 about, which also abuts the surface of the narrow side 3, 4 vertically or almost vertically.

Für den Fall, daß die Lamelle 38 nicht, wie in Fig. 4 dargestellt, in Richtung auf die Körperlängenmitte C gebogen oder gekrümmt ist, sondern eine abgewinkelte Konfiguration aufweist, die in Fig. 3 dargestellt ist, geht die erste Fläche 31 an ihrem unteren Ende 39 in eine ebene Fläche 35 über, die in einem Winkeln α zur Körperlängsachse B geneigt ist und vor Erreichen der Oberfläche der Schmalseiten 3, 4 senkrecht oder nahezu senkrecht zu dieser Oberfläche abknickt und dadurch in eine senkrecht oder nahezu senkrecht verlaufende gerade Fläche 36 übergeht. Die zweite Fläche 32 geht an ihrem hinteren, der Spitze oder Kante 41 abgewandten Ende 42 in eine gerade und unter einem Winkel β zur Körperlängsachse B sowie schräg zur Oberfläche der Schmalseiten 3, 4 verlaufende Fläche 37 über, die vor Erreichen der Oberfläche der Schmalseiten in eine senkrecht oder nahezu senkrecht zu dieser Oberfläche verlaufende, gerade Fläche 38 übergeht. Für den Fall, daß die beiden Winkel α und β gleich groß sind, verlaufen die beiden einander gegenüberliegenden Flächen 35 und 37 parallel zueinander. Üblicherweise ist jedoch der Querschnitt der Lamelle im Bereich des Lamellenübergangs in die Oberfläche 29 der Schmalseiten 3, 4 etwas verstärkt, um die Krafteinleitung zu verbessern und zu verhindern, daß die Lamelle unter den beim Einbau des Geradverbinders in den Hohlraum auftretenden Materialspannungen reißt.In the event that the lamella 38 is not, as shown in Fig. 4, bent or curved towards the body length center C, but has an angled configuration, which is shown in Fig. 3, the first surface 31 goes on its lower End 39 into a flat surface 35, which is inclined at an angle α to the longitudinal axis B of the body and, before reaching the surface of the narrow sides 3, 4, bends perpendicularly or almost perpendicularly to this surface and thereby merges into a straight or almost vertical straight surface 36 . The second surface 32 merges at its rear end 42, which faces away from the tip or edge 41, into a straight surface 37, which extends at an angle β to the longitudinal axis B of the body and obliquely to the surface of the narrow sides 3, 4, and which reaches before the surface of the narrow sides is reached a straight surface 38 running perpendicular or almost perpendicular to this surface merges. In the event that the two angles α and β are of equal size, the two surfaces 35 and 37 lying opposite one another run parallel to one another. Usually, however, the cross section of the lamella in the area of the lamella transition into the surface 29 of the narrow sides 3, 4 is somewhat reinforced in order to improve the introduction of force and to prevent the lamella from tearing under the material stresses which occur in the cavity when the straight connector is installed.

In jedem Fall ist aber die Konstruktion bei den dargestellten Lamellenausführungsformen so ausgebildet, daß das untere Ende 39 der ersten Fläche 31 in Höhe des Auftreffpunktes 40 bzw. der Auftrefflinie der gekrümmten Fläche 34 oder der geraden Fläche 38 auf der Oberfläche 29 der Schmalseiten 3, 4 liegt, wie dies durch die gestrichelte Linie A in Fig. 4 angedeutet ist. Dadurch wird nämlich erreicht, daß beim Einbau des Linearverbinders 1 in die Hohlräume der Abstandhalterprofile die Lamellen zunächst in Richtung auf die Körperlängsachse B zusammengepreßt werden, wobei die im entspannten Zustand der Lamellen 27, 38 parallel zur Körperlängsachse B gerichteten Flächen 31 der Lamellen um das eine Kante darstellende untere Ende 39 dieser Fläche etwas nach innen geschwenkt werden, wodurch sich das Einschieben erleichtert, weil in diesem Fall nicht nur die gesamte Oberfläche der Fläche 31 an der gegenüberliegenden Oberfläche der Hohlprofilwandung anliegt. Sobald der Einschubvorgang beendet ist, der Linearverbinder also seine Einbauposition erreicht hat, tritt dann eine geringfügige Entspannung der Lamelle derart ein, daß diese um die Kante 39 in Richtung auf die gegenüberliegende Oberfläche der Hohlraumwandung zurückkippt, um dadurch die gesamte Fläche 31 zur Anlage auf dieser Oberfläche des Hohlprofilraums zu bringen, sich also gewissermaßen in der Oberfläche des Hohlprofilkörpers festzukrallen, weil diese Oberfläche in der Regel nicht absolut eben ist. Dadurch erhöht sich der Reibschluß wesentlich, so daß die Lamellen insgesamt dem Linearverbinderkörper 1 im Hohlraum der Abstandhalterprofile einen festeren Halt verleihen als dies bisher beobachtet wurde. Die Tatsache, daß der Punkt 39 der Flächen 31, auch ihr unteres Ende genannt, auf derselben Höhe A liegt wie der Auftreffpunkt 40 bzw. die Auftrefflinie der gekrümmten Fläche 34 auf der Oberfläche 29 der Schmalseiten, hat die oben geschilderte günstige Wirkung zur Folge, weil der Lamellenteil, der oberhalb der mit A bezeichneten Linie liegt, nicht in der Weise auf den Schmalseiten des Verbinderkörpers abgestützt wird, wie der unterhalb der Linie A befindliche Lamellenteil und deshalb leichter nach innen, d.h. in Richtung auf die Körperlängsachse B elastisch verformen läßt.In any case, however, the construction in the illustrated lamella embodiments is designed such that the lower end 39 of the first surface 31 is level with the point of impact 40 or the line of impact of the curved surface 34 or the straight surface 38 on the surface 29 of the narrow sides 3, 4 lies, as indicated by the dashed line A in Fig. 4. This means that when the linear connector 1 is installed in the cavities of the spacer profiles, the lamellae are first pressed together in the direction of the body longitudinal axis B, the surfaces 31 of the lamellae oriented parallel to the body longitudinal axis B in the relaxed state of the lamellae 27, 38 by one The lower end 39 of this surface, which represents the edge, is pivoted somewhat inwards, which makes insertion easier, because in this case not only the entire surface of the surface 31 rests on the opposite surface of the hollow profile wall. As soon as the insertion process has ended, that is to say the linear connector has reached its installation position, there is then a slight relaxation of the lamella in such a way that it tilts back around the edge 39 in the direction of the opposite surface of the cavity wall, in order thereby to engage the entire surface 31 on it Bring surface of the hollow profile space, so to speak in the surface of the To firmly claw the hollow profile body, because this surface is usually not absolutely flat. As a result, the frictional engagement increases significantly, so that the lamellae as a whole give the linear connector body 1 in the cavity of the spacer profiles a firmer grip than has previously been observed. The fact that the point 39 of the surfaces 31, also called their lower end, lies at the same height A as the point of incidence 40 or the line of incidence of the curved surface 34 on the surface 29 of the narrow sides, has the favorable effect described above, because the lamella part, which lies above the line labeled A, is not supported on the narrow sides of the connector body in the same way as the lamella part located below the line A and therefore can be elastically deformed inward, ie in the direction of the body longitudinal axis B.

Weitere Ausbildungen der Lamellenkonfiguration können vorsehen, daß die erste Fläche 31, gemessen in Richtung der Körperlängsachse B, doppelt so lang ist wie die zweite Fläche 32, gemessen senkrecht zur Körperlängsachse B, und der Querschnitt der Lamellen 27, 28 kann sich auch in Richtung auf die Spitzen oder Kanten 41 verjüngen.Further configurations of the lamella configuration can provide that the first surface 31, measured in the direction of the body longitudinal axis B, is twice as long as the second surface 32, measured perpendicular to the body longitudinal axis B, and the cross section of the lamellae 27, 28 can also be in the direction of taper the tips or edges 41.

Zur Verbesserung der Festigkeit des Linearverbinderkörpers insgesamt hat es sich, wie aus Fig. 2 ersichtlich, bewährt, die Schmalseiten 3, 4 des vollständig oder nahezu vollständig rinnenförmigen, insbesondere U-förmigen Querschnitts des Geradverbinders, wie bei dem dargestellten Ausführungsbeispiel benutzt, durch einen Quersteg 19 zu verbinden, dessen nach innen gerichtete Oberfläche 43 einen in Richtung der Körperlängsachse B verlaufenden Mittelsteg 44 aufweist.To improve the strength of the linear connector body as a whole, it has proven itself, as can be seen from FIG. 2, the narrow sides 3, 4 of the completely or almost completely channel-shaped, in particular U-shaped cross-section of the straight connector, as used in the illustrated embodiment, by a crosspiece 19 to connect, the inward surface 43 of which has a central web 44 running in the direction of the body longitudinal axis B.

Die an den Schmalseiten im Bereich der Linearverbinderkörpermitte C angeordneten radialen, höckerartigen Verstärkungselemente 5, 6 (Fig. 1) und 44, 45 (Fig. 2) dienen ebenfalls zur Versteifung des U-Profils, um mögliche Verwindungskräfte beim Zusammenbau der Abstandhalterprofilenden aufzunehmen und damit einer Verformung des Linearverbinders in diesem Bereich entgegenzuwirken. Sie können, wie aus Fig. 1 ersichtlich, mit Hinterschneidungen 23, 24 versehen sein, welche als Auflage beim Niederdrücken der als Anschlagelement dienenden Lamellen 7, 8 wirken, wenn der Linearverbinder in den Abstandprofilhohlraum hineingeschoben bzw. eingepreßt wird. Dann überfahren nämlich die Stirnflächen der Abstandhalterprofile die nach außen ragenden Lamellen 7, 8, und da deren freie Enden über den Außenumfang der Lamellen 27, 28 hinausragen, werden sie von diesen Stirnflächen erfaßt und gegen die Körperoberfläche nach unten gebogen. Die mit den Hinterschneidungen 23, 24 im Einbauzustand eine Einheit bildenden Lamellen wirken dann ebenfalls als versteifende Elemente, da sie mit den von den Hinterschneidungen gebildeten Auflagern in kraftübertragender Berührung stehen.The radial, bump-like reinforcing elements 5, 6 (FIG. 1) and 44, 45 (FIG. 2) arranged on the narrow sides in the region of the center of the linear connector body C also serve to stiffen the U-profile in order to absorb possible torsional forces during assembly of the spacer profile ends and thus to counteract a deformation of the linear connector in this area. As can be seen from FIG. 1, they can be provided with undercuts 23, 24 which act as a support when the lamellae 7, 8 serving as stop element are pressed down when the linear connector is pushed or pressed into the spacer profile cavity. Then the end faces of the spacer profiles run over the outwardly projecting lamellae 7, 8, and since their free ends protrude beyond the outer circumference of the lamellae 27, 28, they are gripped by these end faces and bent downward against the body surface. The slats forming a unit with the undercuts 23, 24 in the installed state then also act as stiffening elements, since they are in force-transmitting contact with the supports formed by the undercuts.

Wie insbesondere aus den Figuren 2c und 2e ersichtlich, werden die höckerförmigen Verstärkungselemente 5, 6 in Körperlängsachse B von einer lotrecht auf der Körperoberfläche stehenden Wand 46 und einer schräg zu ihr verlaufenden Wand 47 begrenzt.As can be seen in particular from FIGS. 2c and 2e, the hump-shaped reinforcing elements 5, 6 in the body longitudinal axis B are delimited by a wall 46 standing perpendicular to the body surface and a wall 47 running obliquely to it.

Die Hauptfunktion der im Bereich der Körpermitte des Linearverbinders befindlichen geneigten Lamellen 7, 8 ist jedoch die Anschlagfunktion. Zu diesem Zweck wird zweckmäßigerweise je eine Lamelle 7, 8 beidseitig der Körpermitte C angeordnet, so daß die freien Enden der beiden Lamellen in entgegengesetzte Richtungen weisen. Auf diese Weise ist sichergestellt, daß der Linearverbinder in beliebiger Richtung in die Abstandhalterprofile eingebaut werden kann, ohne daß die Körpermitte C von den Profilstirnseiten überfahren wird.However, the main function of the inclined lamellae 7, 8 located in the area of the center of the body of the linear connector is the stop function. For this purpose, one blade 7, 8 is expediently arranged on both sides of the center of the body C, so that the free ends of the two blades point in opposite directions. In this way it is ensured that the linear connector can be installed in the spacer profiles in any direction without the body end C being run over by the profile end faces.

Die höckerförmigen Verstärkungselemente 5, 6 sind, was die Höhe ihrer Ehebung über die Oberfläche der Schmalseiten 3, 4 anbelangt, wie aus der Zeichnung ersichtlich, kleiner als die verformbaren Lamellen 27, 28 und selbstverständlich auch kleiner als die als Anschlagelement dienenden Lamellen 7, 8. Ihre Höhe kann so bemessen sein, daß sie mit den endseitigen schrägen Auflaufkörpern 21, 22 übereinstimmt, die dazu dienen, das Einführen des Linearverbinders in den Hohlraum der Abstandhalterprofile zu erleichtern.The hump-shaped reinforcing elements 5, 6 are, as regards the height of their elevation above the surface of the narrow sides 3, 4, smaller than the deformable slats 27, 28 and, of course, also smaller than the slats 7, 8 serving as a stop element Their height can be such that they coincide with the oblique ramp bodies 21, 22 on the end, which serve to facilitate the insertion of the linear connector into the cavity of the spacer profiles.

Wie aus den Fig. 1 und 2 ersichtlich, kann der Quersteg 19 des U-förmigen Profils des Linearverbinderkörpers 1 mit Durchbrüchen 20 versehen sein, die na. zu Materialersparnis dienen. Außerdem können Querrippen 17, 18 benutzt werden, die sich beidseitig der Linearkörpermitte C befinden und verhindern, daß das Molekularsieb durch den Spalt, der nach dem Einbau zwischen den beiden gegenüberliegenden Stirnseiten der Abstandhalterprofile gewöhnlich vorhanden ist, hindurchtritt und aus dem Abstandhalterprofil herausfällt. Diese Querrippen können so angeordnet werden, daß sie sich an die die Wandreibung bewirkenden Lamellen 27, 28 anschließen, wie aus den Fig. 1c und Fig. 2c ersichtlich ist. Darüberhinaus können die Lamellen 27, 28 eine Höhe H aufweisen, die etwa der Höhe der Schmalseiten 3, 4 entspricht.As can be seen from FIGS. 1 and 2, the crosspiece 19 of the U-shaped profile of the linear connector body 1 can be provided with openings 20 which, of course, serve to save material. In addition, transverse ribs 17, 18 can be used, which are located on both sides of the linear body center C and prevent the molecular sieve from passing through the gap which is usually present after installation between the two opposite end faces of the spacer profiles and falling out of the spacer profile. These transverse ribs can be arranged in such a way that they connect to the lamellae 27, 28 which cause the wall friction, as can be seen from FIGS. 1c and 2c. In addition, the slats 27, 28 can have a height H which corresponds approximately to the height of the narrow sides 3, 4.
