Description

Die vorliegende Erfindung betrifft ein Trägerelement zum Abstützen eines Flächenelements in einem Flügelrahmen eines Fenster- oder Türflügels, wobei der Flügelrahmen aus Profilabschnitten eines Hohlkammerprofils aufgebaut ist und in mindestens eine Hohlkammer des Hohlkammerprofils ein Verstärkungselement aufgenommen ist, wobei das Trägerelement ein Auflageelement zur Bereitstellung einer Auflagefläche für das Flächenelement umfasst. Darüber hinaus betrifft die vorliegende Erfindung einen Fenster- oder Türflügel, der ein erfindungsgemäßes Trägerelement umfasst.The present invention relates to a support element for supporting a surface element in a sash frame of a window or door sash, the sash frame being constructed from profile sections of a hollow chamber profile and a reinforcing element being accommodated in at least one hollow chamber of the hollow chamber profile, the support element being a support element for providing a support surface for comprises the surface element. In addition, the present invention relates to a window or door sash which comprises a support element according to the invention.

Als derartige Trägerelemente werden im Stand der Technik Glasklotzbrücken eingesetzt, wie sie beispielsweise aus der DE 87 03 052 U1 sowie der DE 39 23 288 A1 bekannt sind. Solche Glasklotzbrücken sind Spritzgussteile aus einem thermoplastischen Material und werden in den Glasfalz eines Fenster- oder Türflügelprofils klemmend eingesetzt, um das einzusetzende Flächenelement, insbesondere die einzusetzende Isolierverglasung, in der erforderlichen Position im Rahmen zu halten. Das von der Glasklotzbrücke zu überbrückende Maß entspricht der Differenz des lichten Rahmenmaßes und dem Maß des einzusetzenden Flächenelements. Dabei wird das Gewicht des Flächenelements über die Glasklotzbrücken in den geodätisch unteren waagerechten Profilabschnitt des Flügelrahmens geleitet. Insbesondere bei großdimensionierten Flügeln kann die Einwirkung dieses Gewichts auf den geodätisch unteren waagerechten Profilabschnitt des Flügelrahmens zu einer starken Durchbiegung dieses Profilabschnitts führen, was ein störungsfreies Öffnen und Schließen des Fensters insbesondere bei hohen Temperaturen negativ beeinträchtigen kann. Um dies zu vermeiden werden die Flächenelemente zur gleichmäßigen Abtragung ihres Gewichts in den Flügelrahmen eingeklebt. Ein derartiges Verkleben des Flächenelements in den Flügelrahmen ist jedoch arbeitsaufwendig und kostenintensiv. Ein weiteres Beispiel eines Flächenelements findet sich in AT 509 673 A1 .Glass block bridges are used as such support elements in the prior art, such as those from DE 87 03 052 U1 as well as the DE 39 23 288 A1 are known. Such glass block bridges are injection molded parts made of a thermoplastic material and are clamped into the glass rebate of a window or door leaf profile in order to hold the surface element to be used, in particular the insulating glazing to be used, in the required position in the frame. The dimension to be bridged by the glass block bridge corresponds to the difference between the clear frame dimension and the dimension of the surface element to be used. The weight of the surface element is guided over the glass block bridges into the geodetically lower horizontal profile section of the sash frame. Particularly with large-sized sashes, the effect of this weight on the geodetically lower horizontal profile section of the sash frame can lead to a strong deflection of this profile section, which can negatively affect trouble-free opening and closing of the window, especially at high temperatures. To avoid this, the surface elements are glued into the sash frame to transfer their weight evenly. However, gluing the surface element into the sash frame in this way is labor-intensive and cost-intensive. Another example of a surface element can be found in AT 509 673 A1 .

An dieser Stelle setzt die vorliegende Erfindung ein, der die Aufgabe zugrunde liegt, ein Trägerelement zum Abstützen eines Flächenelements in einem Flügelrahmen eines Fenster- oder Türflügels zur Verfügung zu stellen, das die Nachteile des Stands der Technik zumindest teilweise überwindet. Insbesondere soll die Gebrauchstauglichkeit eines das erfindungsgemäße Trägerelement umfassenden Fenster- oder Türflügels auch bei hohem Gewicht des Flächenelements gewährleistet sein. Darüber hinaus soll das Flächenelement ohne Verkleben in dem das erfindungsgemäße Trägerelement umfassenden Fenster- oder Türflügel gehalten werden können, ohne dass es zu einem Durchbiegen des Flügelrahmens aufgrund des Gewichts des Flächenelements kommen kann. Darüber hinaus liegt die Aufgabe der vorliegenden Erfindung in der Bereitstellung eines Fenster- oder Türflügels, der ein erfindungsgemäßes Trägerelement umfasst.This is where the present invention comes in, which is based on the object of providing a support element for supporting a surface element in a sash frame of a window or door sash, which at least partially overcomes the disadvantages of the prior art. In particular, the usability of a window or door sash comprising the support element according to the invention should be guaranteed even when the surface element is heavy. In addition, the area element should can be held in the window or door sash comprising the support element according to the invention without gluing, without the sash frame bending due to the weight of the surface element. Furthermore, the object of the present invention is to provide a window or door sash which comprises a support element according to the invention.

Diese und andere Aufgaben werden erfindungsgemäß durch einen Fenster- oder Türflügel mit den Merkmalen des Anspruchs 1 gelöst. Bevorzugte Ausführungsformen der vorliegenden Erfindung sind in den abhängigen Ansprüchen beschrieben.These and other tasks are achieved according to the invention by a window or door sash with the features of claim 1. Preferred embodiments of the present invention are described in the dependent claims.

Gemäß der vorliegenden Erfindung wurde erkannt, dass die Durchbiegung des geodätisch unteren waagerechten Profilabschnitts des Flügelrahmens des Hohlkammerprofils aufgrund des Gewichts des Flächenelements dadurch reduziert werden kann, dass das Gewicht des Flächenelements zumindest teilweise auf einen anderen Profilholm übertragen wird. Erfindungsgemäß wird dies dadurch bewerkstelligt, dass das Trägerelement neben dem Auflageelement zur Bereitstellung einer Auflagefläche für das Flächenelement auch ein mindestens ein Abstützelement zur Abstützung des Trägerelements an einer Profilwand des Hohlkammerprofils sowie mindestens ein Eingriffselement umfasst. Das Eingriffselement kann mit dem Verstärkungselement eines benachbarten Profilabschnitts in Eingriff treten und so zumindest einen großen Teil der Gewichtskraft des Flächenelements auf diesen Profilabschnitt übertragen. Auf diese Weise ist die auf den geodätisch unteren Profilabschnitt einwirkende Gewichtskraft reduziert, so dass die Gefahr des Durchbiegens des geodätisch unteren Profilabschnittts verringert ist. Somit ist ein störungsfreies Öffnen und Schließen des Fensters insbesondere auch bei hohen Temperaturen gewährleistet. Ein Verkleben des Flächenelements in den Flügelrahmen ist nicht mehr erforderlich, was auch für eine bessere Rezyklierbarkeit des erfindungsgemäßen Fenster- oder Türflügel sorgt.According to the present invention, it was recognized that the deflection of the geodetically lower horizontal profile section of the sash frame of the hollow chamber profile due to the weight of the surface element can be reduced by at least partially transferring the weight of the surface element to another profile spar. According to the invention, this is accomplished in that the support element, in addition to the support element for providing a support surface for the surface element, also includes at least one support element for supporting the support element on a profile wall of the hollow chamber profile and at least one engagement element. The engagement element can engage with the reinforcing element of an adjacent profile section and thus transfer at least a large part of the weight of the surface element to this profile section. In this way, the weight force acting on the geodetically lower profile section is reduced, so that the risk of the geodetically lower profile section bending is reduced. This ensures trouble-free opening and closing of the window, especially at high temperatures. Gluing the surface element into the sash frame is no longer necessary, which also ensures better recyclability of the window or door sash according to the invention.

In Figur 1 ist ein Trägerelement 1 gemäß einer Ausführungsform der vorliegenden Erfindung in einer perspektivischen Ansicht gezeigt. Gemäß dieser Ausführungsform ist das erfindungsgemäße Trägerelement 1 als einstückiges Gussbauteil aus einer Zink-Druckgusslegierung ausgebildet. Das erfindungsgemäße Trägerelement 1 umfasst ein Auflageelement 2, das eine geeignete Auflagefläche für ein Flächenelement, insbesondere für eine Isolierverglasung bietet, ein Abstützelement 3, mit dem sich das Trägerelement 1 an einer Profilwand eines Profilabschnitts eines Hohlkammerprofils abstützen kann, sowie Eingriffselemente 4, 4', die mit einem Verstärkungselement 13' in Eingriff gebracht werden können (Fig. 2). Das Auflageelement 2 ist als vorzugsweise ebene Auflageplatte ausgebildet. Das Auflageelement weist eine Bohrung 6 oder mehrere Bohrungen auf, durch die jeweils ein Befestigungsmittel, insbesondere eine Schraube, zur Befestigung des erfindungsgemäßen Trägerelements 1 an einem Flügelrahmen 7 eines erfindungsgemäßen Fensterflügels 8 geführt werden kann. An der Unterseite der Auflageplatte ist ein als ein Paar von Abstützschienen ausgebildetes Abstützelement 3 angeformt. Die Abstützschienen setzen sich als Eingriffsschienen fort, die die Eingriffselemente 4, 4' des Trägerelements 1 gemäß der in Fig. 1 gezeigten Ausführungsform der vorliegenden Erfindung repräsentieren. An ihren Enden weisen die Eingriffselemente 4, 4' jeweils einen Anlageabschnitte 9, 9'auf. Auf den Eingriffselementen 4, 4' befindet sich eine Abdeckplatte 10, die wiederum eine oder mehrere Bohrungen 6' aufweist, durch die jeweils ein Befestigungsmittel, insbesondere eine Schraube, zur weiteren Befestigung des erfindungsgemäßen Trägerelements 1 an einem Flügelrahmen 7 eines erfindungsgemäßen Fensterflügels 8 geführt werden kann. An einer Seite weisen das Auflageelement 2 und die Abdeckplatte 10 eine Abwinkelung 11 auf.In Figure 1 a carrier element 1 according to an embodiment of the present invention is shown in a perspective view. According to this embodiment, the carrier element 1 according to the invention is designed as a one-piece cast component made of a zinc die-cast alloy. The support element 1 according to the invention comprises a support element 2, which offers a suitable support surface for a surface element, in particular for insulating glazing, a support element 3, with which the support element 1 can be supported on a profile wall of a profile section of a hollow chamber profile, and engagement elements 4, 4 ', which can be brought into engagement with a reinforcing element 13 '( Fig. 2 ). The support element 2 is designed as a preferably flat support plate. The support element has a bore 6 or several bores, through which a fastening means, in particular a screw, can be guided for fastening the support element 1 according to the invention to a sash frame 7 of a window sash 8 according to the invention. A support element 3 designed as a pair of support rails is formed on the underside of the support plate. The support rails continue as engagement rails, which hold the engagement elements 4, 4' of the support element 1 according to FIG Fig. 1 shown embodiment of the present invention. At their ends, the engagement elements 4, 4' each have a contact section 9, 9'. On the engagement elements 4, 4' there is a cover plate 10, which in turn has one or more bores 6', through which a fastening means, in particular a screw, is guided for further fastening of the support element 1 according to the invention to a sash frame 7 of a window sash 8 according to the invention can. On one side, the support element 2 and the cover plate 10 have a bend 11.

Eine Einbausituation des in Fig. 1 gezeigten erfindungsgemäßen Trägerelements 1 in einen aus Profilabschnitten 12, 12' gebildeten Flügelrahmen 7 eines erfindungsgemäßen Fensterflügels 8 ist in Fig. 2 in einer schematischen Draufsicht dargestellt. Der Flügelrahmen 7 ist dabei durch Verschweißen von auf Gehrung geschnittenen Profilabschnitten 12, 12' eines Kunststoff-Hohlkammerprofils hergestellt, wobei in Fig. 2 ein Eckbereich des Flügelrahmens 7 mit einem in einer Einbausituation geodätisch unteren, horizontal verlaufenden Profilabschnitt 12 sowie einen damit verbundenen vertikal verlaufenden Profilabschnitt 12' gezeigt ist. In eine Hohlkammer der Profilabschnitte 12, 12', die üblicherweise als Armierungskammer bezeichnet wird, sind vorzugsweise als Stahlarmierung ausgebildete Verstärkungselemente 13, 13' eingesetzt, die sich nicht vollständig in die Ecken des Flügelrahmens 7 erstrecken. In den Eckbereichen weisen die Profilabschnitte 12, 12'also Bereiche auf, in denen kein Verstärkungselement vorhanden ist. Auf das als Auflageplatte ausgebildete Auflageelement 2 kann ein vorzugsweise als Isolierverglasung ausgebildetes Flächenelement (nicht dargestellt) aufgesetzt werden. Das Abstützelement 3 stützt sich an einer Profilwand 14 des Profilabschnitts 12 ab. Gleichermaßen liegen die als Eingriffsschienen ausgebildeten Eingriffselemente 4, 4' des erfindungsgemäßen Trägerelements 1 an der entsprechenden Profilwand 14' des Profilabschnitts 12' an. Der Endabschnitt der Eingriffsschienen erstreckt sich jedoch in das Verstärkungselement 13'des Profilabschnitts 12' hinein. Dabei liegen die Anlageabschnitte 9, 9' an einer Wand des Verstärkungselements 13' an. Dadurch wird das Gewicht des Flächenelements großteils auf den senkrecht verlaufenden Profilabschnitt 12' übertragen, so dass die auf den geodätisch unteren Profilabschnitt 12 einwirkende Gewichtskraft reduziert ist, was die Gefahr des Durchbiegens des geodätisch unteren Profilabschnittts 12 verringert. Somit ist ein störungsfreies Öffnen und Schließen des den erfindungsgemäßen Flügel 8 umfassenden Fensters gewährleistet. Ein Verkleben des Flächenelements in den Flügelrahmen 7 kann unterbleiben, wodurch der erfindungsgemäße Flügel 8 leicht in seine Teile zerlegt werden kann, was die Rezyklierbarkeit des erfindungsgemäßen Fensterflügels 8 verbessert.An installation situation of the in Fig. 1 shown carrier element 1 according to the invention in a sash frame 7 formed from profile sections 12, 12 'of a window sash 8 according to the invention is in Fig. 2 shown in a schematic top view. The sash frame 7 is produced by welding mitred profile sections 12, 12 'of a plastic hollow chamber profile, whereby in Fig. 2 a corner area of the sash frame 7 with a geodetically lower, horizontally extending profile section 12 in an installation situation and a vertically extending profile section 12 'connected to it are shown. Reinforcing elements 13, 13' designed as steel reinforcement are inserted into a hollow chamber of the profile sections 12, 12 ', which is usually referred to as a reinforcing chamber, and do not extend completely into the corners of the sash frame 7. In the corner areas, the profile sections 12, 12' therefore have areas in which no reinforcing element is present. A surface element (not shown), preferably designed as insulating glazing, can be placed on the support element 2 designed as a support plate. The support element 3 is supported on a profile wall 14 of the profile section 12. Likewise, the engagement elements 4, 4' of the carrier element 1 according to the invention, designed as engagement rails, rest on the corresponding profile wall 14' of the profile section 12'. However, the end portion of the engagement rails extends into the reinforcing element 13' of the profile section 12'. The contact sections 9, 9' rest on a wall of the reinforcing element 13'. As a result, the weight of the surface element is largely transferred to the vertical profile section 12 ', so that the weight force acting on the geodetically lower profile section 12 is reduced, which reduces the risk of the geodetically lower profile section 12 bending. This ensures trouble-free opening and closing of the window comprising the sash 8 according to the invention. Gluing the surface element into the sash frame 7 can be omitted, as a result of which the sash 8 according to the invention can be easily disassembled into its parts, which improves the recyclability of the window sash 8 according to the invention.

Der Einbau des erfindungsgemäßen Trägerelements 1 in einen Flügelrahmen 7 ist in Fig. 3 bis Fig. 5 in einer Abfolge von perspektivischen Ansichten eines Eckbereichs eines Flügelrahmens 7 eines Fensterflügels 8 vor (Fig. 3), während (Fig. 4) und nach (Fig. 5) dem Einsetzen des erfindungsgemäßen Trägerelements 1 dargestellt.The installation of the support element 1 according to the invention in a sash frame 7 is in Fig. 3 to Fig. 5 in a sequence of perspective views of a corner area of a sash frame 7 of a window sash 8 ( Fig. 3 ), while ( Fig. 4 ) and after ( Fig. 5 ) the insertion of the carrier element 1 according to the invention is shown.

Der gezeigte Eckbereich ist wiederum aus dem in einer Einbausituation geodätisch unteren, horizontal verlaufenden Profilabschnitt 12 und dem damit verbundenen vertikal verlaufenden Profilabschnitt 12' aufgebaut, wobei entsprechende Profilstücke des Kunststoff-hohlkammerprofils auf Gehrung geschnitten und miteinander verschweißt wurden. In die Armierungskammer sind jeweils Versteifungselemente 13, 13' eingeschoben, wobei sich die Versteifungselemente 13, 13' jeweils nicht ganz bis in die Ecken erstrecken. In diesem Versteifungselement-freien Bereich des Flügelrahmens 7 sind zwei Nuten 15, 15' eingebracht. In den vertikal verlaufenden Profilabschnitt 12' sind zwei Bohrungen 16, 16' eingebracht, durch die wiederum Befestigungsmittel, insbesondere Schrauben, zur Befestigung des erfindungsgemäßen Trägerelements 1 am Flügelrahmen 7 geführt sein können. Die beiden Nuten 15, 15' sind dabei so dimensioniert und voneinander beabstandet, dass sie zur Aufnahme der als ein Paar von Abstützschienen ausgebildeten Abstützelemente 3, 3' und der als ein Paar von Eingriffsschienen ausgebildeten Eingriffselemente 4, 4' geeignet sind. Die Anlageabschnitte 9, 9' der Eingriffselemente 4, 4' werden auf der Seite des vertikal verlaufenden Profilabschnitts 12' in die Nuten 15, 15' eingesetzt (Fig. 4) und das erfindungsgemäße Trägerelement 1 wird solange in den Eckbereich des Flügelrahmens drehend eingeschoben, bis die Anlageabschnitte 9, 9' am Verstärkungselement 13' anliegen. In dieser Position liegen auch die Abstützelemente 3, 3' an der Profilwand 14 des unteren Profilabschnitts 12 an. Dieser Zustand ist in Fig. 5 gezeigt. Abschließend wird das erfindungsgemäße Trägerelement 1 mittels durch die Bohrungen 16, 16' des vertikal verlaufenden Profilabschnitts 12' und entsprechenden Bohrungen 6' im Auflageelement 2 des Trägerelements 1 geführten Befestigungsmitteln (nicht dargestellt) an dem Flügelrahmen festgelegt, wobei die Befestigungsmittel in das Verstärkungselement 13' des vertikal verlaufenden Profilabschnitts 12' eingreifen, so dass die Gewichtkraft eines auf das Auflageelement 2 des erfindungsgemäßen Trägerelements 1 aufgesetzten Flächenelements nicht ausschließlich auf den unteren Profilabschnitt 12, sondern zumindest teilweise auch auf das Verstärkungselement 13' des vertikal verlaufenden Profilabschnitts 12' einwirkt.The corner area shown is in turn made up of the geodetically lower, horizontally extending profile section 12 in an installation situation and the vertically extending one connected to it Profile section 12 'built up, with corresponding profile pieces of the plastic hollow chamber profile being mitred and welded together. Stiffening elements 13, 13' are inserted into the reinforcement chamber, with the stiffening elements 13, 13' not extending all the way into the corners. Two grooves 15, 15 'are made in this stiffening element-free area of the sash frame 7. Two bores 16, 16' are made in the vertically extending profile section 12', through which fastening means, in particular screws, can be guided for fastening the support element 1 according to the invention to the sash frame 7. The two grooves 15, 15' are dimensioned and spaced apart from one another in such a way that they are suitable for receiving the support elements 3, 3' designed as a pair of support rails and the engagement elements 4, 4' designed as a pair of engagement rails. The contact sections 9, 9' of the engagement elements 4, 4' are inserted into the grooves 15, 15' on the side of the vertically extending profile section 12' ( Fig. 4 ) and the carrier element 1 according to the invention is inserted in a rotating manner into the corner area of the sash frame until the contact sections 9, 9 'rest on the reinforcing element 13'. In this position, the support elements 3, 3 'also rest on the profile wall 14 of the lower profile section 12. This condition is in Fig. 5 shown. Finally, the carrier element 1 according to the invention is fixed to the sash frame by means of fastening means (not shown) guided through the holes 16, 16 'of the vertically extending profile section 12' and corresponding holes 6' in the support element 2 of the support element 1, the fastening means being inserted into the reinforcing element 13'. of the vertically extending profile section 12 'intervene, so that the weight of a surface element placed on the support element 2 of the support element 1 according to the invention not only acts on the lower profile section 12, but also at least partially on the reinforcing element 13' of the vertically extending profile section 12'.

In einem Fenster liegt der erfindungsgemäße Flügel 8 über Dichtungen im geschlossenen Zustand des Fensters an einem Blendrahmen an. Dabei ist der erfindungsgemäße Flügel 8 über Beschlagmittel (nicht dargestellt) drehbar gelagert am Blendrahmen festgelegt.In a window, the sash 8 according to the invention lies against a frame via seals when the window is closed.
