Definitions

  • the invention relates to a connector for hollow profiles, in particular for forming spacer frames for insulating glass panes filled with drying agent.
  • Such a connector is known from DE-OS 34 08 600, which consists of a U-shaped hollow body and has spring tongues and / or retaining lugs for securing the position of its legs in the hollow profile.
  • the known connector is closed on the end and can only be inserted into the hollow profiles of the spacer frames after the desiccant has been filled in. As a result, 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 degree of filling of the remaining hollow profile areas is not optimal because of the subsequently introduced connector, since space must be left for the connector, which it does not completely fill.
  • 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.
  • a corner connector which has a slotted cover tongue on the end faces which is intended to encompass the folded edge of a hollow profile bent or rolled from sheet metal.
  • the interior of the corner connector is not filled with desiccant.
  • DE-OS 26 15 746 also teaches a U-shaped corner connector, the central web of which lies flat against the hollow profile wall lying on the inside of the frame. The end faces are closed to keep the drying agent out of the interior of the corner connector.
  • the invention solves this problem with the features in the characterizing part of the main claim.
  • the drying agent can now pass through the corner connector by means of the axially continuous cavity and the open end faces.
  • 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.
  • 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.
  • the invention thus also relates to a plug connection from two hollow profiles and a plug connector, and to a method for filling a spacer frame.
  • 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 by the plug-in connector, in particular in the form of a corner connector. This applies to both miter cut and butted hollow profiles. In the encountered embodiment remains anyway the corner area is free on the outside, so that when the corner connector is fully inserted, both hollow profiles can be filled. There is also a positive optical effect at the joint of the hollow profiles. Due to the neighboring center bar, especially with metallic connectors, gaps at the joint are not noticeable.
  • 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 simultaneously act horizontally and vertically. Overall, this results in better locking and guiding, for which purpose only a small number of lugs is necessary.
  • the middle retaining tabs can also serve as a stop for the attached hollow profiles.
  • the retaining lugs can only protrude laterally.

Description

Die Erfindung betrifft einen Steckverbinder für Hohlprofile, insbesondere zur Bildung von mit Trocknungsmittel befüllten Abstandshalterrahmen für Isolierglasscheiben.The invention relates to a connector for hollow profiles, in particular for forming spacer frames for insulating glass panes filled with drying agent.

Aus der DE-OS 34 08 600 ist ein derartiger Steckverbinder bekannt, der aus einem U-förmigen Hohlkörper besteht und Federzungen und/oder Rückhaltenasen zur Lagesicherung seiner Schenkel im Hohlprofil aufweist. Der vorbekannte Steckverbinder ist stirnseitig geschlossen und kann in die Hohlprofile der Abstandshalterrahmen erst nach Einfüllung des Trocknungsmittels eingesetzt werden. Dadurch befindet sich an den Stoßstellen des Rahmens kein Trocknungsmittel, was hinsichtlich der dort stattfindenden Diffusionsprozesse aber wünschenswert wäre. Außerdem ist wegen des nachträglich eingeführten Steckverbinders der Füllungsgrad der übrigen Hohlprofilbereiche nicht optimal, da Platz für den Steckverbinder gelassen werden muß, den dieser nicht vollständig ausfüllt. 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.Such a connector is known from DE-OS 34 08 600, which consists of a U-shaped hollow body and has spring tongues and / or retaining lugs for securing the position of its legs in the hollow profile. The known connector is closed on the end and can only be inserted into the hollow profiles of the spacer frames after the desiccant has been filled in. As a result, there is no drying agent at the joints of the frame, which would be desirable with regard to the diffusion processes taking place there. In addition, the degree of filling of the remaining hollow profile areas is not optimal because of the subsequently introduced connector, since space must be left for the connector, which it does not completely fill. 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.

Aus dem DE-GM 80 17 644 ist ein Eckverbinder bekannt, 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-GM 80 17 644 a corner connector is known which has a slotted cover tongue on the end faces which is intended to encompass the folded edge of a hollow profile bent or rolled from sheet metal. The interior of the corner connector is not filled with desiccant.

Schließlich lehrt die DE-OS 26 15 746 noch einen U-förmigen Eckverbinder, dessen Mittelsteg an der zur Rahmeninnenseite liegenden Hohlprofilwand flächig anliegt. Die Stirnseiten sind geschlossen, um das Trocknungsmittel aus dem Innenraum des Eckverbinders fernzuhalten.Finally, DE-OS 26 15 746 also teaches a U-shaped corner connector, the central web of which lies flat against the hollow profile wall lying on the inside of the frame. The end faces are closed to keep the drying agent out of the interior of the corner connector.

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 Kennzeichen des Hauptanspruchs.The invention solves this problem with the features in the characterizing part of the main claim.

Vermittels des axial durchgängigen Hohlraumes und der offenen Stirnseiten kann das Trocknungsmittel nun den Eckverbinder 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 drying agent can now pass through the corner 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.

Die Erfindung betrifft damit auch eine Steckverbindung aus zwei Hohlprofilen und einem Steckverbinder sowie ein Verfahren zum Befüllen eines Abstandshalterrahmens.The invention thus also relates to a plug connection from two hollow profiles and a plug connector, and to a method for filling a spacer frame.

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, insbesondere in Gestalt eines Eckverbinders. Das gilt sowohl bei auf Gehrung geschnittenen als auch bei im Eckbereich gestoßenen Hohlprofilen. Bei der gestoßenen Ausführungsform bleibt ohnehin der Eckbereich außenseitig frei, so daß bei vollständig eingeführtem Eckverbinder beide Hohlprofile befüllt werden können. Es ergibt sich außerdem ein positiver optischer Effekt an der Stoßstelle der Hohlprofile. Durch den benachbarten Mittelsteg fallen, vor allem bei metallischen Steckverbindern, Spalte an der Stoßstelle nicht auf.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 by the plug-in connector, in particular in the form of a corner connector. This applies to both miter cut and butted hollow profiles. In the encountered embodiment remains anyway the corner area is free on the outside, so that when the corner connector is fully inserted, both hollow profiles can be filled. There is also a positive optical effect at the joint of the hollow profiles. Due to the neighboring center bar, especially with metallic connectors, gaps at the joint are not noticeable.

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.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.
Für Geradverbinder können die mittleren Rückhaltenasen auch als Anschlag für die aufgesteckten Hohlprofile dienen.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 simultaneously act horizontally and vertically. Overall, this results in better locking and guiding, for which purpose only a small number of lugs is necessary.
For straight connectors, the middle retaining tabs can also serve as a stop for the attached hollow profiles.

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 zum Eckbereich 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 rising towards the corner area. 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.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.

Der erfindungsgemäße Steckverbinder kann als Geradverbinder oder als Eckverbinder gestaltet 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 be designed as a straight connector or as a corner connector. 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 9 zeigen einen Steckverbinder (1), der einmal als Geradverbinder (2) und einmal als vorzugsweise rechtwinklig gebogener Eckverbinder (3) 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. 10 zeigt den Abstandshalterrahmen (18) in beiden Ausführungen mit Geradverbinder (2) und Eckverbinder (3).The exemplary embodiments in FIGS. 1 to 9 show a plug connector (1) which is designed once as a straight connector (2) and once as a corner connector (3) which is preferably bent at right angles. 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. 10 shows the spacer frame (18) in both versions with straight connector (2) and corner connector (3).

Der Steckverbinder (1) ist in beiden Ausführungen als im Querschnitt U-förmig gebogenes Stanzteil aus Stahlblech hergestellt.The connector (1) is manufactured in both versions as a stamped part made of sheet steel with a U-shaped cross section.

Der Geradverbinder (2) weist im Innern einen axial frei durchgängigen Hohlraum (16) und stirnseitig große Durchgangsöffnungen auf. Im Gegensatz zu bekannten 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 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 one hollow profile (11) into 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 hollow profiles (11, 12) are plugged together, the drying agent (15) can also collect at the connection point (20) in the cavity (16).
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 either side 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. 7 - 9 geben eine Variation des Geradverbinders (2) wieder. Der Mittelsteg (6) ist hier durchgängig glatt und ohne Federzungen ausgebildet. Wie Fig. 9 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.7 - 9 show a variation of the straight connector (2). The middle web (6) is here consistently smooth and without spring tongues. As illustrated in FIG. 9, 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.A number of retaining lugs (10) are provided in the region of the web edges (24), which preferably run parallel to the central web (6), for guiding and fixing the straight connector (2) in the hollow profiles (11, 12). The retaining lugs (10) are punched out at the front and on the side by undercuts (23) in the side webs (7) and are in the form of elongated tongues which are axially directed in the push-on direction. The undercuts (23) are oval and large in the side area of the retaining lugs and create space for a bending tool. As shown in FIGS. 7 and 8, the retaining lugs (10) are both lateral, i.e. horizontally, as well as upwards, i.e. bent 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.7 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. 7 shows this position with a hollow profile (11).

Fig. 4 bis 6 zeigen einen Eckverbinder (3) mit aufgesteckten Hohlprofilen (11,12). Der im Querschnitt U-förmige Eckverbinder (3) ist so gebogen, daß der Mittelsteg (6) an der Winkelinnenseite liegt, während die Seitenstege (7) nach außen weisen. Die Schenkel (4,5) des Eckverbinders (3) sind damit nach außen offen. Der Mittelsteg (6) liegt außerdem flächig an den zur Innenseite des Abstandshalterrahmens (18) weisenden Hohlprofilwänden (19) an. Zur Stabilisierung besitzt der Eckverbinder (3) im Eckbereich (17) eine zur Winkelaußenseite gewölbte Verstärkungssicke (14).4 to 6 show a corner connector (3) with attached hollow profiles (11, 12). The corner connector (3), which is U-shaped in cross section, is bent so that the central web (6) lies on the inside of the angle, while the side webs (7) point outwards. The legs (4,5) of the corner connector (3) are thus open to the outside. The central web (6) also lies flat against the hollow profile walls (19) pointing towards the inside of the spacer frame (18). For stabilization, the corner connector (3) in the corner area (17) has a reinforcing bead (14) that is curved toward the outside of the angle.

Der Eckverbinder (3) weist ebenfalls einen axial durchgängigen Hohlraum (16) auf und ist stirnseitig offen. Hierdurch können die aufgesteckten Hohlprofile (11,12) vom Eckbereich aus mit Trocknungsmitteln (15) befüllt werden, das sich im weiteren auch innerhalb der Winkelschenkel (4,5) ansammelt. Im Eckbereich (17) dienen die gebogenen Seitenstege (7) als seitliche Führung beim Einfüllen des Trocknungsmittels (15). Nach dem Befüllen wird der Eckbereich von außen abgedichtet und versiegelt.The corner connector (3) also has an axially continuous cavity (16) and is open at the end. As a result, the attached hollow profiles (11, 12) can be filled with drying agents (15) from the corner area, which also accumulates within the angle legs (4, 5). In the corner area (17), the curved side webs (7) serve as a lateral guide when filling the drying agent (15). After filling, the corner area is sealed and sealed from the outside.

Die Winkelschenkel (4,5) sind wie in den vorhergehenden Ausführungsbeispielen im Querschnitt der Kontur des Hohlprofiles (11,12) angepaßt und in ihrem jeweiligen Hohlprofil (11,12) formschlüssig geführt. Die Anlage an den Profilseitenwänden wird hier jedoch durch vier dreieckige Rückhaltenasen gesichert, die jeweils am oberen Stegrand (24) freigestanzt und seitlich ausgebogen sind. Zur Führung in der Hochachse des Hohlprofiles (11,12) sind die Seitenstege (7) der Profilhöhe angepaßt. Wie Fig. (6) verdeutlicht, kommen die Stegoberkanten (24) an den schrägen Dachflächen bzw dem Absatz (21) der Hohlprofile (11,12) zur Anlage.As in the previous exemplary embodiments, the angled legs (4, 5) are adapted in cross-section to the contour of the hollow profile (11, 12) and are positively guided in their respective hollow profile (11, 12). However, the system on the side walls of the profile is secured here by four triangular retaining lugs, each punched out on the upper edge of the web (24) 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). As shown in Fig. (6), 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) zum Eckbereich (17) hin an. Im Eckbereich (17) ist sie 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 Fig. 4 zeigt der Schenkel (5) diese Stegform.In addition, the side webs (7) can be wedge-shaped. The height of the top edge of the web (24) increases from the front end of the angle legs (4, 5) to the corner area (17). In the corner area (17) 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. In Fig. 4 the leg (5) shows this web shape.

Die Seitenstege (7) weisen im Eckbereich (17) seitlich nach außen vortretende Ausprägungen (13) auf, die durch Vorprägen der Platine und Fertigprägen am gebogenen Eckverbinder hergestellt werden. Die Seitenstege (7) erreichen dadurch annähernd die gleiche Breite wie die Hohlprofile (11,12) und bilden mit den geraden Rändern der Ausprägungen (13) Anschlagkanten für die Hohlprofile (11,12).
Die Winkelschenkel (4,5) besitzen zum erleichterten Einführen in die Hohlprofile (11,12) Anschrägungen (25)am Mittelsteg (6) und den Seitenstegen (7).The side webs (7) have in the corner area (17) laterally outward protrusions (13), which are produced by pre-stamping the board and finish stamping on the curved corner connector. The side webs (7) thereby reach approximately the same width as the hollow profiles (11, 12) and form stop edges for the hollow profiles (11, 12) with the straight edges of the stampings (13).
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. Insbesondere können die zweiseitig wirkenden Rückhaltenasen (10) von Fig 7 bis 9 beim Eckverbinder (3) und darüberhinaus auch bei beliebigen anderen U-förmigen Steckverbindern eingesetzt werden.The shapes of the retaining lugs (10) and spring tongues (8, 9) shown in the exemplary embodiments can be varied, combined and interchanged. In particular, the double-sided retaining lugs (10) of FIGS. 7 to 9 can be used for the corner connector (3) and, moreover, also for any other U-shaped connector.

Zum Befüllen des in Fig. 10 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. 10, 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.
