Hohlprofile, insbesondere für Abstandshalterrahmen von Isolierglasscheiben, mit den Merkmalen im Oberbegriff des Hauptanspruchs .Hollow profiles, in particular for spacer frames of insulating glass panes, with the features in the preamble of the main claim.
Ein solcher Steckverbinder ist aus der EP-0 283 689 AI bekannt. Er besitzt an seinem Boden oder Mittelsteg und an den Seitenwänden ein oder mehrere Rückhalteelemente, die sich in der Wandung der aufgeschobenen Hohlprofile verkrallen und den Steckverbinder gegen unbeabsichtigtes Abziehen sichern. Der Steckverbinder wird mit seinemSuch a connector is known from EP-0 283 689 AI. It has one or more retaining elements on its bottom or middle bar and on the side walls, which are clawed into the wall of the pushed-on hollow profiles and secure the connector against unintentional removal. The connector comes with its
Mittelsteg zur Rahmeninnenseite liegend in die Hohlprofile gesteckt. Letztere haben an ihrer rahmeninnenseitigen Wand in der Regel ein oder mehrere Perforationsreihen, die den Zutritt der im Scheibeninnenraum befindlichen Luft zu dem im Abstandshalterrahmen enthaltenen Trocknungsmittel gestatten. Auf diesen Perforationen liegt der vorbekannte Steckverbinder mit seinem Mittelsteg auf oder greift mit den Rückhalteelementen zwischen die Perforationen. Die Rückhalteelemente stützen sich dabei an den glatten Profilinnenwänden ab.Center bar on the inside of the frame inserted into the hollow profiles. The latter generally have one or more rows of perforations on their wall on the inside of the frame, which allow the air in the window interior to access the drying agent contained in the spacer frame. The previously known plug connector lies on these perforations with its central web or engages with the retaining elements between the perforations. The retaining elements are supported on the smooth inner walls of the profile.
Es ist Aufgabe der vorliegenden Erfindung, einen Steckverbinder mit einem verbesserten Rückhalt in den Hohlprofilen aufzuzeigen.It is an object of the present invention to show a connector with an improved retention in the hollow profiles.
Die Erfindung löst diese Aufgabe mit den Merkmalen im Hauptanspruch.The invention solves this problem with the features in the main claim.
Beim erfindungsgemäßen Steckverbinder sind im Bereich der Perforationen ein oder mehrere Federnasen angeordnet, die an den Perforationen oder Lochreihen angreifen. DieIn the connector according to the invention, one or more spring tabs are arranged in the area of the perforations, which engage the perforations or rows of holes. The
Perforationen werden meist von außen in die Hohlprofilwand gestanzt oder gepreßt und bilden auf der Wandinnenseite erhabene Preßwülste oder dergleichen andere Überstände. An diesen können sich die Federnasen formschlüssig verhaken und bieten dadurch einen größeren Rückhalt und Auszugswiderstand als beim Angriff an einer glatten Profilinnenwand. Federnasen bieten dabei einen besonders guten Rückhalt, wie er mit starren Rückhalteelementen nicht in gleicher Weise erreicht werden kann.Perforations are usually punched or pressed from the outside into the hollow profile wall and form on the inside of the wall raised press beads or the like other supernatants. The spring lugs can catch on these positively and thus offer greater retention and pull-out resistance than when attacking a smooth inner wall of the profile. Spring lugs offer particularly good support, which cannot be achieved in the same way with rigid retaining elements.
Die Federnasen sind vorzugsweise aus der Wandung des Steckverbinders freigeschnitten oder freigestanzt und ausgebogen. Dadurch befinden sich in ihrem Bereich Wandöffnungen, die auch im Steckverbinderbereich einen Zutritt der Scheibeninnenluft zum Trocknungsmittel gestatten. Hierfür ist es im weiteren vorteilhaft, wenn der Steckverbinder offene Stirnseiten hat und in seinem Innenraum Trocknungsmittel aufnimmt.The spring lugs are preferably cut out of the wall of the connector or punched out and bent out. As a result, there are wall openings in their area, which also allow access to the interior of the pane to the drying agent in the connector area. For this it is further advantageous if the connector has open end faces and absorbs drying agent in its interior.
Die Federnasen sind vorzugsweise in einer Vertiefung angeordnet. Dies vergrößert die Federlänge und gibt den Federnasen mehr Elastizität. Dabei genügt es, wenn die Federnasen mit ihren Rändern etwa bis auf Höhe der Vertiefungsränder reichen.The spring lugs are preferably arranged in a recess. This increases the spring length and gives the spring lugs more elasticity. It is sufficient if the feather lugs extend with their edges approximately to the level of the recess edges.
Die Federnasen sind bei Anordnung mehrerer paralleler Perforationsreihen dementsprechend nebeneinander angeordnet. Sie befinden sich dabei etwa auf gleicher Höhe und sind dabei aber bewußt ein kleines Stück axial zueinander versetzt. Dies hat Vorteile mit Hinblick auf den häufig vorkommenden Axialversatz benachbarter Perforationsreihen. Durch den Federnasenversatz ist sichergestellt, daß zumindest eine oder einige Federnase (n) die Perforationsbuckel treffen und hintergreifen. Die Federnasen sollen möglichst in die Täler zwischen die Perforationsbuckel greifen. Im Mittelbereich besitzt der Steckverbinder vorzugsweise eine gegenüber den Vertiefungen erhabene Deckplatte, die an der Innenwandung der Hohlprofile anliegt und die Verbindungs- oder Stoßstelle der Hohlprofile dichtend übergreift und abdeckt.The spring noses are accordingly arranged side by side when arranging several parallel rows of perforations. They are at about the same height and are deliberately offset axially from each other. This has advantages with regard to the frequently occurring axial misalignment of adjacent rows of perforations. The spring nose offset ensures that at least one or some spring nose (s) meet and engage behind the perforation bosses. The spring noses should reach into the valleys between the perforation bosses as far as possible. In the central region, the connector preferably has a cover plate which is raised in relation to the depressions and which lies against the inner wall of the hollow profiles and sealingly engages and covers the connection or joint of the hollow profiles.
In den Unteransprüchen sind weitere vorteilhafte Ausgestaltungen der Erfindung angegeben. Further advantageous embodiments of the invention are specified in the subclaims.

Figur 1 bis 4 zeigen einen Steckverbinder (1) für Hohlprofile (2) . Hierbei handelt es sich vorzugsweise um einen Geradverbinder. Der Steckverbinder (1) kann aber auch ein Eckwinkel sein. Die Hohlprofile (2) werden beidseitig auf den Steckverbinder (1) aufgeschoben.Figures 1 to 4 show a connector (1) for hollow profiles (2). This is preferably a straight connector. The connector (1) can also be a corner bracket. The hollow profiles (2) are pushed onto the connector (1) on both sides.
Die Hohlprofile (2) bilden vorzugsweise einenThe hollow profiles (2) preferably form one
Abstandshalterrahmen für eine Isolierglasscheibe. Sie können aus einem beliebig geeigneten Werkstoff, z.B. einer Leichtmetall-Legierung bestehen. Im bevorzugten Ausführungsbeispiel handelt es sich um sehr dünnwandige Profile aus Edelstahl. Solche Profile haben eine gewisse Labilität und verforrαen sich beim Ablängen an den Schnittkanten. Außerdem neigen die dünnen Profilwände dazu, sich beim Einkrallen von Rückhalteelementen des Steckverbinders (1) zu verformen und auszuweichen. Bei solchen Profilen können die Haltekräfte daher nur in einem begrenzten Maß übertragen und aufgenommen werden. Die Hohlprofile (2) haben an ihrer zur Rahmeninnenseite (15) bzw. zur Scheibeninnenseite weisenden Wand ein oder mehrere in Axialrichtung verlaufende reihen- oder linienförmige Perforationen (3,4). Diese bestehen aus einer Vielzahl von außen eingestanzter oder eingedrückter kleiner Löcher, die an der Innenseite der Profilwand hochstehende Wülste, Buckel, Krater oder dergleichen aufwerfen. Die Buckel sind punktweise vorhanden und haben in Axialrichtung einen Abstand. Figur 4 verdeutlicht diese Ausbildung in der Querschnittsdarstellung.Spacer frame for an insulating glass pane. They can consist of any suitable material, for example a light metal alloy. In the preferred embodiment, there are very thin-walled profiles made of stainless steel. Such profiles have a certain instability and deform when cut to length at the cut edges. In addition, the thin profile walls tend to deform and dodge when the retaining elements of the connector (1) are clawed into place. With such profiles, the holding forces can therefore only be transmitted and absorbed to a limited extent. The hollow profiles (2) have one or more row or line perforations (3, 4) running in the axial direction on their wall facing the inside of the frame (15) or the inside of the pane. These consist of a large number of small holes punched or pressed in from the outside, which raise raised beads, humps, craters or the like on the inside of the profile wall. The humps are present at certain points and are spaced apart in the axial direction. Figure 4 illustrates this design in the cross-sectional representation.
Der Steckverbinder (1) besitzt im Bereich der Perforation (en) (3,4) ein oder mehrere elastische Federnasen (9,10). Die Federnasen (9,10) sind schmal ausgebildet und haben vorzugsweise eine Breite, die im wesentlichen derjenigen der Perforation (3,4) entspricht. Die Federnasen (9,10) sind an dem zur Rahmeninnenseite (15) weisenden Boden (5) des Steckverbinders (1) angeordnet. Sie sind beidseits der Mittellinie (17) des Steckverbinders (1) angeordnet und jeweils entgegengesetzt zu dieser Mittellinie (17) gerichtet.The connector (1) has one or more elastic spring lugs (9, 10) in the area of the perforation (s) (3, 4). The spring lugs (9, 10) are narrow and preferably have a width which essentially corresponds to that of the perforation (3, 4). The spring lugs (9, 10) are arranged on the bottom (5) of the plug connector (1) which faces the inside of the frame (15). They are arranged on both sides of the center line (17) of the plug connector (1) and are directed opposite to this center line (17).
Die Federnasen (9,10) verkrallen sich beim Aufstecken der Hohlprofile (2) an den Perforationen (3,4) und legen sich federnd möglichst hinter die Buckel oder Krater bzw. greifen in deren Zwischenräume. Dadurch spreizen sich die Federnasen (9,10) elastisch gegen die Hohlprofile (2) und bieten einen guten Rückhalt, der ein unbeabsichtigtes Abziehen der Hohlprofile (2) vom Steckverbinder (1) verhindert.The spring lugs (9, 10) claw at the perforations (3, 4) when the hollow profiles (2) are attached and, if possible, lie behind the humps or craters or reach into the spaces between them. As a result, the spring lugs (9, 10) spread elastically against the hollow profiles (2) and offer good support that prevents the hollow profiles (2) from being unintentionally removed from the plug connector (1).
Die Federnasen (9,10) haben besondere Vorteile für die bevorzugten dünnwandigen und relativ labilen Hohlprofile (2) . Im Bereich der Perforationen (3,4) bieten die durch die Buckel oder Krater gebildeten Wandverformungen eine erhöhte Stabilität der Hohlprofilwand und einen verbesserten Verformungswiderstand. Die von den Federnasen (9,10) eingeleiteten Haltekräfte werden dadurch ohne Wandverfor ung aufgenommen und abgetragen.The spring lugs (9, 10) have particular advantages for the preferred thin-walled and relatively unstable hollow profiles (2). In the area of the perforations (3, 4), the wall deformations formed by the humps or craters offer increased stability of the hollow profile wall and improved resistance to deformation. The spring noses (9,10) holding forces are absorbed and removed without wall deformation.
Figur 1 und 3 zeigen verschiedene Ausführungsbeispiele für die Zahl und Anordnung der Federnasen (9,10) . In den gezeigten Ausführungsformen sind jeweils zwei parallele Perforationen (3,4) vorhanden. Dementsprechend sind auch zwei Reihen von Federnasen (9,10) vorgesehen, von denen die Federnasen (9) in die Perforationen (3) und die Federnasen (10) in die Perforationen (4) greifen. Die Federnasen (9,10) sind dabei paarweise nebeneinander angeordnet. Sie befinden sich in etwa auf gleicher Höhe und sind dabei ein kleines Stück axial gegeneinander versetzt. Wenn mehrere Federnasen (9,10) hintereinander auf jeweils einer Verbinderhälfte angeordnet sind, haben diese untereinander in Axialrichtung den gleichen Abstand, so daß bei allen Federnasenpaarungen in etwa der gleiche Axialversatz besteht. In Längsrichtung können aber auch die Abstände der Federnasen (9) bzw. (10) untereinander variieren.Figures 1 and 3 show different embodiments for the number and arrangement of the spring lugs (9,10). In the embodiments shown there are two parallel perforations (3, 4). Accordingly, two rows of spring lugs (9, 10) are also provided, of which the spring lugs (9) engage in the perforations (3) and the spring lugs (10) engage in the perforations (4). The spring lugs (9, 10) are arranged side by side in pairs. They are at approximately the same height and are axially offset from each other by a small amount. If several spring lugs (9, 10) are arranged one behind the other on each connector half, these have the same distance from one another in the axial direction, so that there is approximately the same axial offset in all spring lug pairs. In the longitudinal direction, however, the distances between the spring lugs (9) and (10) can also vary.
Der Axialversatz der nebeneinander liegenden Federnasen (9,10) ist vorzugsweise einige Zehntelmillimeter groß. Durch den Axialversatz der Federnasen (9,10) wird den in der Praxis häufig vorkommenden Axialverschiebungen der Lochungen in den Perforationsreihen (3,4) Rechnung getragen. Der Federnasenversatz kann z.B. in etwa ein Viertel oder die Hälfte des Lochabstandes der Perforationen (3,4) ausmachen.The axial offset of the spring lugs (9, 10) lying next to one another is preferably a few tenths of a millimeter in size. The axial offset of the spring lugs (9, 10) takes into account the axial displacements of the perforations in the perforation rows (3, 4) that are common in practice. The spring nose offset can e.g. make up about a quarter or half of the hole spacing of the perforations (3, 4).
Die Federnasen (9,10) sind beidseits der Mittellinie (17) mit Abstand zu dieser angeordnet. Sie befinden sich in wannenartigen Vertiefungen (11) des Bodens (5) . Figur 2 verdeutlicht z.B. diese Anordnung. Mit der Ausführungsform von Figur 1 sind in jeder Vertiefung (11) jeweils ein Paar Federnasen (9,10) angeordnet. In der Variante von Figur 3 hat jede Vertiefung (11) zwei Paare von Federnasen (9,10). Zwischen den Vertiefungen (11) bzw. Federnasen (9,10) hat der Boden (5) im Mittelbereich (17) eine erhabene Deckplatte (12) , die in Einbaustellung dicht an der zur Rahmeninnenseite (15) weisenden Hohlprofilwand anliegt und die dort befindliche Verbindungsstelle der Hohlprofile (2) überdeckt und abdichtet. An den äußeren Rändern des Steckverbinders (1) können weitere erhabene Bereiche an die Vertiefungen (11) anschließen.The spring lugs (9, 10) are arranged on both sides of the center line (17) at a distance from it. They are located in trough-like depressions (11) in the bottom (5). Figure 2 illustrates this arrangement, for example. With the embodiment of FIG. 1, a pair of spring lugs (9, 10) are arranged in each recess (11). In the variant of FIG. 3, each recess (11) has two pairs of spring lugs (9, 10). Between the recesses (11) or spring lugs (9, 10), the bottom (5) in the central region (17) has a raised cover plate (12) which, in the installed position, lies tightly against the hollow profile wall facing the inside of the frame (15) and the one located there Connection point of the hollow profiles (2) covers and seals. At the outer edges of the connector (1) further raised areas can connect to the recesses (11).
Wie Figur 2 verdeutlicht, haben die Federnasen (9,10) eine in etwa an die Höhe der Vertiefungen (11) angepaßte Länge. Sie reichen in etwa bis auf Höhe der oberen Vertiefungsränder bzw. auf Höhe der Deckplatte (12) .As illustrated in FIG. 2, the spring lugs (9, 10) have a length which is approximately matched to the height of the depressions (11). They extend approximately to the level of the upper recess edges or at the level of the cover plate (12).
Die Federnasen (9,10) sind aus dem Boden (5) freigeschnitten und ausgebogen. Dadurch entstehen im Boden Öffnungen. In der Ausführungsform von Figur 1 sind die Freischnitte knapp bemessen und die Öffnungen relativ klein. In der Variante von Figur 3 sind die Freischnitte (14) größer. Hierdurch sind auch die entstehenden Nasenöffnungen im Boden (5) größer. Dadurch können sich einerseits die Federnasen (9,10) unter Einwirkung der Perforationsbuckel leichter verformen. Andererseits geben die größeren Öffnungen der Scheibeninnenluft mehr Zutritt zu dem vorzugsweise im Steckverbinder (1) angesammelten granulierten Trocknungsmittel.The spring lugs (9, 10) are cut out of the base (5) and bent out. This creates openings in the floor. In the embodiment of Figure 1, the free cuts are tight and the openings are relatively small. In the variant of FIG. 3, the free cuts (14) are larger. As a result, the resulting nostrils in the base (5) are larger. On the one hand, this allows the spring lugs (9, 10) to deform more easily under the influence of the perforation bosses. On the other hand, the larger openings in the inner pane air give more access to the granulated drying agent, which is preferably collected in the connector (1).
Der Boden (5) kann in den erhabenen Bereichen (12) entlang der Perforationen (3,4) ein oder mehrere Rinnen (13) aufweisen. Wie Figur 4 verdeutlicht, nehmen diese Rinnen (13) die Perforationsbuckel auf und decken diese ab. Die Rinnen (13) können zumindest in den äußeren Bereichen ebenfalls kleine Öffnungen für den Luftzutritt aufweisen. In Figur 4 ist die Einbaulage zur besserenThe bottom (5) can have one or more channels (13) in the raised areas (12) along the perforations (3, 4). As shown in FIG. 4, these channels (13) take up the perforation bosses and cover them. The channels (13) can also have small openings for air access, at least in the outer regions. In Figure 4, the installation position is for the better
Übersichtlichkeit mit einem größeren Bodenabstand als real dargestellt. In der Praxis liegt der Boden (5) mit der Deckplatte (12) dicht an der innenliegenden Hohlprofilwand an.Clarity with a larger ground clearance than shown real. In practice, the floor (5) lies with the Cover plate (12) close to the inner hollow profile wall.
Der Steckverbinder (1) besitzt im Mittenbereich (17) ein oder mehrere Mittenanschläge (7) .
