Description

Die Erfindung betrifft einen geraden Steckverbinder für Hohlprofile mit den Merkmalen im Oberbegriff des Hauptanspruchs.The invention relates to a straight connector for hollow profiles with the features in the preamble of the main claim.

Aus dem DE-U 82 27 371.5 ist ein gerader Steckverbinder mit U-förmigem Querschnitt bekannt, der Federzungen aufweist und für den Einsatz in Hohlprofilen von Abstandshalterrahmen für Isolierglasscheiben vorgesehen ist. Der Steckverbinder hat geschlossene Stirnseiten, so daß die Hohlprofile vor dem Einsatz des Steckverbinders mit dem Trocknungsmittel befüllt werden müssen. Außerdem ist beim Befüllen noch ausreichend Platz für den Steckverbinder zu lassen, den dieser aber nicht vollständig ausfüllt. Der Befüllungsgrad ist daher nicht optimal. Ferner befindet sich an den Stoßstellen des Rahmens kein Trocknungsmittel, was hinsichtlich der dort stattfindenden Diffusionsprozesse aber wünschenswert wäre. Der vorbekannte Steckverbinder zwingt damit zur Befüllung der Hohlprofile vor der Verbindung dieser Teile und u.U. auch zum Biegen der Hohlprofile im gefüllten Zustand.From DE-U 82 27 371.5 a straight connector with a U-shaped cross section is known, which has spring tongues and is intended for use in hollow profiles of spacer frames for insulating glass panes. The connector has closed end faces, so that the hollow profiles must be filled with the drying agent before the connector is used. In addition, there must be enough space for the connector when filling, but this does not completely fill it. The degree of filling is therefore not optimal. Furthermore, there is no drying agent at the joints of the frame, which would be desirable with regard to the diffusion processes taking place there. The known connector thus forces the hollow profiles to be filled before connecting these parts and possibly. also for bending the hollow profiles when filled.

Der bekannte Steckverbinder besitzt an der Verbindungsstelle der aufgesteckten Hohlprofile zwei Anschläge in Form von dreieckigen Vorsprüngen, die von den Seitenstegen nach unten vorragen. Beim Aufschieben setzen sie den Hohlprofilen Widerstand entgegen und graben sich in das Profilmaterial ein. Es läßt sich damit nicht immer ein dichter Profilschluß an der Verbindungsstelle erreichen.The known connector has two stops in the form of triangular projections at the junction of the attached hollow profiles, which protrude downward from the side webs. When pushed on, they oppose the hollow profiles and dig into the profile material. It is not always possible to achieve a tight profile closure at the connection point.

Die DE-A 3 408 600 zeigt einen ähnlichen geraden Steckverbinder, der ebenfalls stirnseitig geschlossen ist und in die Hohlprofile erst nach Einfüllen des Trocknungsmittels eingesetzt werden kann.DE-A 3 408 600 shows a similar straight connector, which is also closed at the end and can only be inserted into the hollow profiles after the desiccant has been filled in.

Aus der DE-A 3 037 015 und der CA-A 1 006 052 sind Eckwinkel mit offenen Stirnseiten und einem durchgängigen Hohlraum bekannt. Das DE-U 80 17 644 beinhaltet einen Eckverbinder, der an den Stirnseiten eine geschlitzte Abdeckzunge aufweist, die den Falzgrat eines aus Blech gebogenen oder gerollten Hohlprofils umgreifen soll. Der Innenraum des Eckverbinders ist nicht mit Trocknungsmittel befüllt.From DE-A 3 037 015 and CA-A 1 006 052 corner brackets with open end faces and a continuous cavity are known. DE-U 80 17 644 includes a corner connector which has a slotted cover tongue on the end faces which is intended to grip around the folded edge of a hollow profile which is bent or rolled from sheet metal. The interior of the corner connector is not filled with desiccant.

Es ist daher Aufgabe der vorliegenden Erfindung, einen höheren Befüllungsgrad der Hohlprofile zu erreichen und die Handhabung der Steckverbinder und der Hohlprofile zu verbessern.It is therefore an object of the present invention to achieve a higher degree of filling of the hollow profiles and to improve the handling of the connectors and the hollow profiles.

Die Erfindung löst diese Aufgabe mit den Merkmalen im Hauptanspruch.
Vermittels des axial durchgängigen Hohlraumes und der offenen Stirnseiten kann das Trocknungsmittel nun den Steckverbinder passieren. Dies hat zum einen den Vorteil, daß die Hohlprofile nach dem Zusammenfügen befüllt werden können. Hierdurch wird nicht nur eine leichtere Handhabung, sondern auch eine bessere Verteilung und ein höherer Befüllungsgrad der Hohlprofile erreicht. Die Erfindung erlaubt auch eine wirtschaftliche Verwertung von Verschnittresten, insbesondere von kurzen Hohlprofilstücken. Diese werden durch Steckverbinder zusammengesetzt und anschließend in einem Zug befüllt . Andererseits kann sich nun auch Trocknungsmittel im Bereich des Steckverbinders ansammeln und an der besonders diffusionsträchtigen Verbindungsstelle der Hohlprofile in der gewünschten Weise wirksam werden.The invention solves this problem with the features in the main claim.
The drying agent can now pass through the connector by means of the axially continuous cavity and the open end faces. On the one hand, this has the advantage that the hollow profiles can be filled after assembly. As a result, not only easier handling, but also better distribution and a higher degree of filling of the hollow profiles is achieved. The invention also allows economical use of leftovers, especially short hollow sections. These are put together by connectors and then filled in one go. On the other hand, drying agent can now also accumulate in the area of the connector and become effective in the desired manner at the particularly diffusion-providing connection point of the hollow profiles.

Als Anschlag für die aufgesteckten Hohlprofile dienen beim erfindungsgemäßen geraden Steckverbinder die mittleren, gegeneinander gerichteten Rückhaltenasen. Sie federn und verschwinden in den aufgesteckten Hohlprofilen und ermöglichen einen dichten Profilschluß an der Verbindungsstelle.The middle, mutually directed retaining lugs serve as a stop for the plugged-on hollow profiles in the straight connector according to the invention. They spring and disappear in the attached hollow profiles and allow a tight profile closure on the Liaison.

In Ergänzung hierzu ist es günstig, wenn der Mittelsteg des Steckverbinders zur Rahmeninnenseite hin liegt und damit ein Übertreten des Trocknungsmittels aus seinem Hohlrauam in die Isolierglasscheibe verhindert. Dies ermöglicht auch eine Befüllung der Hohlprofile durch den eingesteckten Steckverbinder. Es ergibt sich außerdem ein positiver optischer Effekt an der Verbindungsstelle der Hohlprofile. Durch den benachbarten Mittelsteg fallen, vor allem bei metallischen Steckverbindern, Spalte an der Verbindungsstelle nicht auf. Für die vorgenannten Effekte empfiehlt es sich im weiteren auch, den Mittelsteg des Steckverbinders glatt und ohne Federzungen auszubilden und flächig an die rahmeninnenseitige Hohlprofilwand anzulegen.In addition to this, it is expedient if the central web of the connector lies on the inside of the frame and thus prevents the drying agent from passing out of its hollow space into the insulating glass pane. This also enables the hollow profiles to be filled through the inserted plug connector. There is also a positive optical effect at the junction of the hollow profiles. Due to the adjacent center bar, especially with metallic connectors, there are no gaps at the connection point. For the above-mentioned effects, it is also advisable to make the center bar of the connector smooth and without spring tongues and to lay it flat against the inside of the hollow profile wall.

Eine Arretierung und Führung der Steckverbinder in den Hohlprofilen findet dann nur über Rückhaltenasen statt. Besonders günstig ist es, wenn diese mittels Hinterschneidungen freigelegt sind. Das ermöglicht ein Abbiegen der Rückhaltenasen nach zwei Richtungen, so daß eine Nase zugleich horizontal und vertikal wirken kann. Insgesamt ergibt sich hierdurch eine bessere Arretierung und Führung, wozu auch nur eine geringe Nasenzahl nötig ist.The connectors are then locked and guided in the hollow profiles only via retaining lugs. It is particularly advantageous if these are exposed by means of undercuts. This allows the retaining lugs to bend in two directions, so that a lug can act both horizontally and vertically. Overall, this results in better locking and guidance, for which only a small number of noses is required.

Alternativ können aber auch die Rückhaltenasen nur seitlich abstehen. Die Führungsaufgabe in der Vertikalen wird dann durch die Höhenanpassung der Seitenstege erfüllt. Eine besonders gute Führung ergibt sich, wenn die Seitenstege in der Höhe variabel sind und eine zur Verbindungsstelle hin ansteigende Keilform aufweisen.
Desgleichen ist es auch möglich, Federzungen an den Mittelstegen anzuordnen.Alternatively, the retaining lugs can only protrude laterally. The vertical guide is then performed by adjusting the height of the side bars. A particularly good guidance results if the side webs are variable in height and have a wedge shape that increases towards the connection point.
Likewise, it is also possible to arrange spring tongues on the central webs.

Der erfindungsgemäße Steckverbinder bzw. die Steckverbindung können neben Abstandshalterrahmen auch für beliebige andere Arten und Einsatzzwecke von Hohlprofilen verwendet werden, wenn diese ebenfalls mit einem Granulat oder dgl. befüllt werden müssen.In addition to spacer frames, the plug connector according to the invention or the plug connection can also be used for any other types and purposes of hollow profiles if these also have to be filled with granules or the like.

Der erfindungsgemäße Steckverbinder kann aus Metall, Kunststoff oder anderen Materialien bestehen und eine einseitig offene U-Form oder einen seitlich geschlossenen Kastenquerschnitt aufweisen. Nachdem die Querschnittsform des Steckverbinders sich nach dem Querschnitt des Hohlprofiles richtet, kann diese auch kreisrund, oval, polygonartig oder in beliebiger anderer Weise ausgebildet sein. Für den Anwendungsfall bei Abstandshalterrahmen mit metallischen Hohlprofilen empfiehlt es sich wegen der besseren Haftung, den Steckverbinder als Biege-Stanzteil aus Stahlblech herzustellen.The connector according to the invention can consist of metal, plastic or other materials and have a U-shape that is open on one side or a box cross-section that is closed on the side. After the cross-sectional shape of the connector depends on the cross-section of the hollow profile, it can also be circular, oval, polygonal or in any other way. In the case of spacer frames with hollow metal profiles, it is advisable to manufacture the connector as a bent stamped part from sheet steel due to its better adhesion.

Die Ausführungsbeispiele in Figur 1 bis 6 zeigen einen Steckverbinder (1), der als Geradverbinder (2) ausgebildet ist. Der gezeigte Steckverbinder (1) dient zur Verbindung von Hohlprofilen (11,12) zu einem Abstandshalterrahmen (18) für Isolierglasscheiben, der innenseitig mit einem Trocknungsmittel (15) befüllt ist. Fig. 7 zeigt den Abstandshalterrahmen (18) mit Geradverbinder (2).The exemplary embodiments in FIGS. 1 to 6 show a plug connector (1) which is designed as a straight connector (2). The connector (1) shown is used to connect hollow profiles (11, 12) to a spacer frame (18) for insulating glass panes, which is filled on the inside with a drying agent (15). Fig. 7 shows the spacer frame (18) with straight connector (2).

Der Steckverbinder (1) ist in beiden Ausführungen als im Querschnitt U-förmig gebogenes Stanzteil aus Stahlblech hergestellt. Er ist im Querschnitt der Kontur des Hohlprofiles (11,12) angepaßt und im jeweiligen Hohlprofil (11,12) formschlüssig geführt.The connector (1) is manufactured in both versions as a stamped part made of sheet steel with a U-shaped cross section. It is adapted in cross-section to the contour of the hollow profile (11, 12) and is guided in a form-fitting manner in the respective hollow profile (11, 12).

Der Geradverbinder (2) weist im Innern einen axial frei durchgängigen Hohlraum (16) und stirnseitig große Durchgangsöffnungen auf. Im Gegensatz zu bekannten geraden Steckverbindern sind stirnseitig keine Abdeckungen vorhanden. Allenfalls sind die Seitenstege (7) und der Mittelsteg (6) ein wenig nach innen gebogen, um eine Anschrägung (25) für ein leichteres Aufstecken der Hohlprofile (11,12) zu schaffen.The straight connector (2) has an axially freely continuous cavity (16) and large through openings on the front. In contrast to known straight connectors, there are no covers on the front. At most, the side webs (7) and the middle web (6) are bent a little inward to create a bevel (25) for easier attachment of the hollow profiles (11, 12).

Das Trocknungsmittel (15) kann durch die stirnseitigen Öffnungen den Hohlraum (16) passieren und so über die Verbindungsstelle (20) von einem Hohlprofil (11) ins nächste Hohlprofil (12) gelangen. Auf diese Weise ist auch von einer Seite aus die Befüllung mehrerer hintereinander angeordneter Hohlprofile möglich. Bei zusammengesteckten Hohlprofilen (11,12) kann sich das Trocknungsmittel (15) auch an der Verbindungsstelle (20) im Hohlraum (16) sammeln.
Der Geradverbinder wird dazu vorzugsweise so in die Hohlprofile (11,12) gesteckt, daß sein Mittelsteg (6) zur Innenseite des Abstandshalterrahmens (18) weist. Ein U-förmiger Geradverbinder (2) erleichtert mit seiner Wannenform auch das Befüllen mit Trocknungsmittel (15).The drying agent (15) can pass through the end openings into the cavity (16) and thus get from the hollow profile (11) to the next hollow profile (12) via the connection point (20). In this way, it is also possible to fill several hollow profiles arranged one behind the other from one side. When the hollow profiles (11, 12) are plugged together, the drying agent (15) can also collect in the cavity (16) at the connection point (20).
For this purpose, the straight connector is preferably inserted into the hollow profiles (11, 12) in such a way that its central web (6) faces the inside of the spacer frame (18). With its trough shape, a U-shaped straight connector (2) also makes it easier to fill with drying agent (15).

Im Ausführungsbeispiel von Fig. 1 - 3 weist der Geradverbinder (2) beidseits seiner Mitte jeweils ein paar Federzungen (8) und (9) auf, die jeweils aus dem Mittelsteg (6) hochgebogen sind und zur Mitte weisen. In den Zeichnungen ist zur besseren Erkennbarkeit der Abstand des Mittelsteges (6) von der gegenüberliegenden Hohlprofilwand größer als real dargestellt. Die Federzungenpaare (8,9) sind jeweils symmetrisch zur Mitte angeordnet. Die außenliegenden Federzungen (8) sind breiter als die innenliegenden Federzungen (9) und besitzen einen gebogenen Rand. Beidseits der Mitte sind in den Seitenstegen (7) des Geradeverbinders (2) jeweils dreieckige Rückhaltenasen (10) freigestanzt und ausgebogen. Der Geradverbinder (2) hat damit in jedem Hohlprofil (11,12) einen vierfachen Rückhalt, der ein unbeabsichtigtes Abziehen unmöglich macht. Die Federzungen (8,9) und die Rückhaltenasen (10) dienen außerdem der Führung des Geradverbinders (2) in den Hohlprofilen (11,12). Sie können auch zu Abdichtungszwecken der Hohlprofilkontur angepaßt sein.In the exemplary embodiment of FIGS. 1-3, the straight connector (2) has a pair of spring tongues (8) and (9) on both sides of its center, which are each bent up from the central web (6) and point towards the center. In the drawings, the distance of the central web (6) from the opposite hollow profile wall is shown larger than real for better visibility. The spring tongue pairs (8, 9) are each arranged symmetrically to the center. The outer spring tongues (8) are wider than the inner spring tongues (9) and have a curved edge. Triangular retaining lugs (10) are punched out and bent out on both sides of the center in the side webs (7) of the straight connector (2). The straight connector (2) thus has a fourfold retention in each hollow profile (11, 12), which makes unintentional removal impossible. The spring tongues (8,9) and the retaining lugs (10) also serve to guide the straight connector (2) in the hollow profiles (11, 12). They can also be adapted to the hollow profile contour for sealing purposes.

Fig. 4 - 6 geben eine Variation des Geradverbinders (2) wieder. Der Mittelsteg (6) ist hier durchgängig glatt und ohne Federzungen ausgebildet. Wie Fig. 6 verdeutlicht, liegt der Mittelsteg (6) vollflächig an der zur Innenseite des Abstandshalterrahmens (18) gelegenen Hohlprofilwand (19) an. Die Höhe der Seitenstege (7) ist so abgestimmt, daß der Mittelsteg mit Druck und damit dicht anliegt.Fig. 4 - 6 show a variation of the straight connector (2) again. The middle web (6) is here consistently smooth and without spring tongues. As illustrated in FIG. 6, the central web (6) lies over the entire surface of the hollow profile wall (19) located on the inside of the spacer frame (18). The height of the side webs (7) is coordinated so that the center web lies tightly against pressure.

Zur Führung und Fixierung des Geradverbinders (2) in den Hohlprofilen (11,12) sind mehrere Rückhaltenasen (10) im Bereich der vorzugsweise parallel zum Mittelsteg (6) verlaufenden Stegoberkanten (24) vorgesehen. Die Rückhaltenasen (10) sind vorn und seitlich durch Hinterschneidungen (23) in den Seitenstegen (7) freigestanzt und besitzen die Form von länglichen, axial in Aufsteckrichtung gerichteten Zungen. Die Hinterschneidungen (23) sind im Seitenbereich der Rückhaltenasen oval und großflächig und schaffen Platz für ein Biegewerkzeug. Wie Fig. 7 und 8 zeigen, sind die Rückhaltenasen (10) sowohl seitlich, d.h. horizontal, als auch nach oben, d.h. vertikal abgebogen. Sie stehen über die Stegfläche und über den oberen Stegrand (24) vor und stemmen sich federnd sowohl in die Seitenwand des aufgesteckten Hohlprofils (11,12), als auch in den Absatz (21) am Übergang von der Profilseitenwand in die geneigte Dachwand. Hierdurch führen die Rückhaltenasen (10) den Geradverbinder (2) horizontal und vertikal im Hohlprofil. Durch die gegeneinander gerichtete Lage verhindern sie auch ein Abziehen der Hohlprofile.To hold and fix the straight connector (2) in the hollow profiles (11, 12), several retaining tabs (10) are provided in the area of the upper edge of the web (24), which preferably runs parallel to the central web (6). The retaining lugs (10) are punched out at the front and on the side by undercuts (23) in the side webs (7) and have the shape of elongated tongues which are axially directed in the direction of attachment. The undercuts (23) are oval and large in the side area of the retaining lugs and create space for a bending tool. 7 and 8 show, the retaining lugs (10) are bent laterally, ie horizontally, and upwards, ie vertically. They protrude above the web surface and over the upper web edge (24) and resiliently brace themselves both in the side wall of the attached hollow profile (11, 12) and in the heel (21) at the transition from the profile side wall into the inclined roof wall. As a result, the retaining lugs (10) guide the straight connector (2) horizontally and vertically in the hollow profile. Due to the opposing position, they also prevent the hollow profiles from being pulled off.

In der Mitte des Geradverbinders (2) sind zwei gegeneinander gerichtete Rückhaltenasen (10) mit einer gemeinsamen Hinterschneidung (23) angeordnet. Sie sind nur seitlich und dabei etwas stärker als die anderen Rückhaltenasen (10) nach außen gebogen und bilden einen Anschlag (22) für das jeweils von der Gegenseite her aufgesteckte Hohlprofil. Fig.4 zeigt diese Stellung mit einem Hohlprofile (11).In the middle of the straight connector (2) two opposing retaining lugs (10) with a common undercut (23) are arranged. They are only bent to the side and a little stronger than the other retaining lugs (10) and form a stop (22) for the hollow profile that is attached from the opposite side. Fig. 4 shows this position with a hollow profile (11).

Die Anlage an den Profilseitenwänden kann auch durch vier dreieckige Rückhaltenasen gesichert werden (nicht dargestellt), die jeweils am oberen Stegrand freigestanzt und seitlich ausgebogen sind. Zur Führung in der Hochachse des Hohlprofiles (11,12) sind die Seitenstege (7) der Profilhöhe angepaßt. Die Stegoberkanten (24) kommen an den schrägen Dachflächen bzw. dem Absatz (21) der Hohlprofile (11,12) zur Anlage.The system on the profile side walls can also be secured by four triangular retaining lugs (not shown), each of which is punched out at the upper edge of the web and bent out to the side. The side webs (7) are adapted to the profile height for guidance in the vertical axis of the hollow profile (11, 12). The upper web edges (24) come to rest on the sloping roof surfaces or the shoulder (21) of the hollow profiles (11, 12).

Zusätzlich können die Seitenstege (7) keilförmig ausgebildet sein. Die Höhe der Stegoberkante (24) steigt dabei vom stirnseitigen Ende der Winkelschenkel (4,5) zur Verbindungsstelle (20) hin an. Sie ist vorzugsweise etwas größer als die Führungshöhe des Hohlprofiles (11,12). Die Seitenstege (7) schneiden dadurch zur Sicherung des Verbundes etwas in das Hohlprofil (11,12) ein.In addition, the side webs (7) can be wedge-shaped. The height of the top edge of the web (24) rises from the front end of the angle legs (4, 5) to the connection point (20). It is preferably somewhat larger than the guide height of the hollow profile (11, 12). The Side bars (7) thus cut something into the hollow profile (11, 12) to secure the bond.

Die Winkelschenkel (4,5) besitzen zum erleichterten Einführen in die Hohlprofile (11,12) Anschrägungen (25) am Mittelsteg (6) und den Seitenstegen (7).The angled legs (4, 5) have bevels (25) on the central web (6) and the side webs (7) for easier insertion into the hollow profiles (11, 12).

Die in den Ausführungsbeispielen gezeigten Formen der Rückhaltenasen (10) und Federzungen (8,9) können variiert, kombiniert und untereinander vertauscht werden.The shapes of the retaining lugs (10) and spring tongues (8, 9) shown in the exemplary embodiments can be varied, combined and interchanged.

Zum Befüllen des in Fig. 7 gezeigten Abstandshalterrahmens (18) werden zuerst die Steckverbinder (1,2,3) in die Hohlprofile (11,12) eingesetzt. Anschließend wird das Trocknungsmittel (15) eingeführt, wobei die Steckverbinder (1,2,3) als Führungsrinne dienen. Je nach Ausführung können bei einem einstückigen Abstandshalterrahmen die Hohlprofile vor oder nach dem Biegen befüllt werden.In order to fill the spacer frame (18) shown in FIG. 7, the plug connectors (1, 2, 3) are first inserted into the hollow profiles (11, 12). The drying agent (15) is then introduced, the plug connectors (1, 2, 3) serving as a guide trough. Depending on the version, the hollow profiles can be filled before or after bending in a one-piece spacer frame.
