Definitions
- the invention is directed to a Brefalzlformater with at least one air guide chamber in which a flow restrictor in the form of at least one pivotally mounted in the air guide chamber flap, which comprises a closure element and a counterweight forming return element, is arranged, wherein the return element and the closure element formurchurchmmbare surfaces , And the restoring element on its side facing the air duct chamber wall facing side has at least one cooperating with the wall and the flap in its open position driving spring element.
- a Novafalzlmediaer is from the DE 199 29 133 C2 known.
- This Novafalzlformater consists of an air duct chamber in which a flow restrictor is arranged in the form of a pivotally mounted flap.
- This pivotally mounted flap consists of a light bent formed closure element and an integrally formed in the form of a return element counterweight. The counterweight pushes the flap in its open position and the flap is moved at a sufficiently high air flow against the force of the counterweight in its closure position closing the air guide chamber.
- a Novafalzlmediaer which can be arranged operatively in vertically or approximately vertically arranged picnicfalzabêten a window element or a door element, is from the WO 2006/074839 A1 known.
- This known Novafalzlformater has a hinged flap, which is provided on its one of the air guide chamber delimiting wall facing side with a spring element which is permanently in contact with this wall and presses the flap in its open position.
- This embodiment is constructed so that the flap closes the air flow path inside the air guide chamber, which occurs because the apertured return element is applied to a wall bounding the air guide chamber.
- the invention is therefore based on the object to provide a solution which makes it possible to obtain in a generic Recfalzlmediaer without affecting the air flow path and the maximum possible volume flow for a given size of its full functionality both when installed in a horizontal and vertical installation position ,
- this object is achieved in that the at least one spring element is formed in a formed in this page, bottom closed trough interchangeable by means of a releasable latching connection to the return element.
- the spring element-bearing wall or side of the return element in the form of a trough, it is possible, embedded therein and thus at least partially recessed, to arrange a spring element, which bounding to the adjacent and the air supply chamber Wall rests and drives the pendulum flap in its open position.
- the return element can be tight against the limiting wall of the ventilation chamber.
- the at least one spring element is replaceable attached to the return element. This makes it possible to replace the spring element, but this also in the production process after production of the pendulum flap to attach to this. It is also possible to decide whether a Novafalzlformater should have a spring element or not. As a result, only one body of the flow restrictor is needed, which can then be flexibly equipped with a spring element.
- a particularly advantageous possibility of connection between spring element and restoring element consists largely in that the at least one spring element is fastened by means of a releasable latching connection to the return element.
- the invention further provides that the at least one spring element made of metal or plastic.
- the Fig. 1 shows a schematic representation of the view of a window element from the inside of an interior ago.
- the window element is shown with its frame 1 and the window wing 2 arranged pivotally therein.
- the sealing the window seam 5 on the building exterior side between the window frame 1 and sash 2 seal is in the lower part of the window at two positions 3a, 3b removed, so that there as shown by the arrows 4, from the outside air can flow into the window seam 5.
- the air then flows as in Fig. 1 represented by arrows to a Novafalzlformater 6, from which the air then flows in the direction of the arrows 7 in the space provided with the window element interior. It is also possible that in the reverse direction and air from the interior reaches the building exterior.
- the Destalzlmediaer 6 is in the also from the FIGS. 5 and 6 apparent position in the upper, transverse Novafalz Stud the window element arranged. It comprises an air-guiding chamber 8 in which a volume flow limiter 9 in the form of a flap pivotably mounted about an axis 10 is arranged. This flap comprises a slightly curved designed closure element 11 and a counterweight forming return element 12. As from the FIGS. 5 and 6 it can be seen, the closure element 11 in the in Fig.
- the trough 16 is dimensioned such that the spring element 15 in the in Fig. 6 shown closure position of the flap completely immersed in the trough 16 and thus has substantially no over this top of the return element protruding areas, so that the pivoting region of the Volumenstrombeskyrs 9 between the gap-shaped opening 14 completely opening opening position Fig. 5 and the gap-shaped opening 14 occluding closure position according to Fig. 6 remains pivotable about the same angle and way, as a same size, but without spring element 15 trained Novafalzlformater.
- the trough 16 is bottom-side, i. closed on its side facing the closure element 11 side.
- a first provided therein latching opening 17 may be closed with a locking foot 18 of the spring element 15 to form a releasable latching connection.
- the spring element 15 is thereby replaceably mounted in the trough 16 or on the return element 12.
- the spring element 15 has the shape of a bending elastic biased rod or tongue-like element and is preferably made of plastic, but may also be made of metal.
- the spring element 15 drives and forces the flow restrictor 9 in the in Fig. 5 illustrated Opening position, wherein the spring force counteracts a flowing from outside to inside airflow. If there is no air flow or an air flow flowing from the inside to the outside, the spring force of the spring element 15 forces the volume flow limiter into the air flow limiter Fig. 5 illustrated opening position. On the other hand, the spring element 15 acts at sufficiently high, in the air guide chamber 8 from the outside of the building entering air volume flow as a damper or damping element, the all too violent and sudden pivoting of the flow restrictor 9 in the in Fig. 6 shown closure position prevents.
- the embodiment relates to a window, so the Novafalzlformater is equally between a door frame and a door leaf or a door wing circumferentially formed fold to be arranged.

Description
Die Erfindung richtet sich auf einen Fensterfalzlüfter mit mindestens einer Luftführungskammer in der ein Volumenstrombegrenzer in Form mindestens einer in der Luftführungskammer schwenkbeweglich gelagerten Klappe, die ein Verschlusselement und ein dazu ein Gegengewicht ausbildendes Rückstellelement umfasst, angeordnet ist, wobei das Rückstellelement und das Verschlusselement undurchströmbare Oberflächen ausbilden, und das Rückstellelement auf seiner einer die Luftführungskammer begrenzenden Wand zugewandten Seite mindestens ein mit der Wand zusammenwirkendes und die Klappe in ihre Öffnungsstellung treibendes Federelement aufweist.The invention is directed to a Fensterfalzlüfter with at least one air guide chamber in which a flow restrictor in the form of at least one pivotally mounted in the air guide chamber flap, which comprises a closure element and a counterweight forming return element, is arranged, wherein the return element and the closure element formurchurchmmbare surfaces , And the restoring element on its side facing the air duct chamber wall facing side has at least one cooperating with the wall and the flap in its open position driving spring element.
Um die ausreichende Belüftung von Innenräumen auch bei geschlossenen Fenstern oder Türen sicherzustellen, sind sogenannte Fensterfalzlüfter bekannt, die in den Fensterfalz zwischen Blendrahmen und Fensterrahmen oder in den Türfalz zwischen Türrahmen und Türblatt oder Türrahmen eingebaut werden. Zur Ausbildung eines durch den jeweiligen Fensterfalzlüfter führenden Belüftungsweges von der Gebäudeaußenseite zu dem jeweiligen Innenraum hin und zurück, werden Teile der Dichtung zwischen Blendrahmen und Fensterflügel oder Türrahmen und Türflügel oder Türblatt entfernt, so dass sich ein Luftführungsweg und Luftströmungsweg ausbildet, der einen Luftaustausch zwischen der Gebäudeaußenseite und dem jeweiligen Innenraum ermöglicht.In order to ensure adequate ventilation of interiors even with closed windows or doors, so-called Fensterfalzlüfter known, which are installed in the Fensterfalz between window frame and window frame or in the door rebate between the door frame and door leaf or door frame. To form a leading through the respective Fensterfalzlüfter ventilation path from the building exterior to the respective interior back and forth, parts of the seal between the frame and casement or door frame and door or door leaf are removed, so that an air guide path and air flow path is formed, an air exchange between the Outside of the building and the respective interior allows.
Ein Fensterfalzlüfter ist aus der
Ein Fensterfalzlüfter, der auch in senkrecht oder annähernd senkrecht angeordneten Fensterfalzabschnitten eines Fensterelementes oder eines Türelementes funktionsfähig angeordnet werden kann, ist aus der
Bei gattungsgemäßen Fensterfalzlüftern, wie sie beispielsweise der
Insbesondere aber würde eine solche geänderte Anordnung des Gegengewichtes relativ zum Verschlusselement dazu führen, dass dieses "früher", d.h. nach einer Schwenkbewegung aus der Verschlussstellung des Verschlusselementes in eine Öffnungsposition nach Überstreichen eines geringeren Winkels, bei einer Öffnungsbewegung der Pendelklappe auf einer Bodenfläche der Luftführungskammer aufliegt, als dies sonst bei einem Fensterfalzlüfter gleicher Baugröße der Fall ist. Dies hätte dann aber zur Konsequenz, dass der maximal mögliche Luftspalt zwischen dem Verschlusselement und der Luftführungskammer kleiner würde, was dazu führt, dass dadurch der maximal durch den Fensterfalzlüfter hindurchführbare Volumenstrom geringer würde.In particular, however, such an altered arrangement of the counterweight relative to the closure element would result in this "earlier", ie after a pivoting movement from the closure position of the closure element to an opening position after passing over a smaller angle, resting on a bottom surface of the air conduction chamber during an opening movement of the pendulum flap , as is otherwise the case with a Fensterfalzlüfter the same size. However, this would have the consequence that the maximum possible air gap between the closure element and the air guide chamber would be smaller, which leads to as a result, the maximum volume flow that can be passed through the window folding fan would be lower.
Diese vorstehend beschriebenen Probleme weist der gattungsgemäße, aus der
Der Erfindung liegt daher die Aufgabe zugrunde, eine Lösung zu schaffen, die es ermöglicht, bei einem gattungsgemäßen Fensterfalzlüfter ohne Beeinträchtigung des Luftströmungsweges und des bei einer vorgegebenen Baugröße maximal möglichen Volumenstroms dessen volle Funktionsfähigkeit sowohl bei einem Einbau in waagerechter als auch in senkrechter Einbauposition zu erhalten.The invention is therefore based on the object to provide a solution which makes it possible to obtain in a generic Fensterfalzlüfter without affecting the air flow path and the maximum possible volume flow for a given size of its full functionality both when installed in a horizontal and vertical installation position ,
Bei einem Fensterfalzlüfter der eingangs näher bezeichneten Art wird diese Aufgabe erfindungsgemäß dadurch gelöst, dass das mindestens eine Federelement in einer in dieser Seite ausgebildeten, bodenseitig verschlossenen Mulde auswechselbar mittels einer lösbaren Rastverbindung an dem Rückstellelement befestigt ist.In a Fensterfalzlüfter of the type described in more detail, this object is achieved in that the at least one spring element is formed in a formed in this page, bottom closed trough interchangeable by means of a releasable latching connection to the return element.
Durch die erfindungsgemäße Ausgestaltung der das Federelement tragenden Wand oder Seite des Rückstellelementes in Form einer Mulde ist es möglich, darin eingelassen und somit zumindest zum Teil versenkt, ein Federelement anzuordnen, das an der benachbarten und die Luftzuführungskammer begrenzenden Wand anliegt und die Pendelklappe in ihre Öffnungsstellung treibt. Auf diese Weise kann die Winkelstellung zwischen dem das Gegengewicht ausbildenden Rückstellelement und dem Verschlusselement gegenüber einer Ausführungsform gleicher Baugröße ohne Federelement beibehalten und damit der bei einer gegebenen Baugröße maximal mögliche, durch den Fensterfalzlüfter führbare Luftvolumenstrom unverändert beibehalten werden. Außerdem kann sich das Rückstellelement eng an die begrenzende Wand der Lüftungskammer anlegen. Insbesondere ist es dank des Federelementes möglich, den Fensterfalzlüfter senkrecht in den senkrecht verlaufenden seitlichen Fensterfalzbereichen eines Fensters oder einer Türe einzubauen. Ohne Federelement würde das Rückstellelement in dieser Position keine Wirkung entfalten.Due to the inventive design of the spring element-bearing wall or side of the return element in the form of a trough, it is possible, embedded therein and thus at least partially recessed, to arrange a spring element, which bounding to the adjacent and the air supply chamber Wall rests and drives the pendulum flap in its open position. In this way, the angular position between the counterweight forming the restoring element and the closure element with respect to an embodiment of the same size without spring element maintained and thus the maximum possible for a given size, feasible through the Fensterfalzlüfter air volume flow can be maintained unchanged. In addition, the return element can be tight against the limiting wall of the ventilation chamber. In particular, it is possible thanks to the spring element to install the Fensterfalzlüfter perpendicular to the vertical lateral Fensterfalzbereichen a window or door. Without a spring element, the restoring element would have no effect in this position.
Da das Federelement einem Verschleiß unterworfen ist, aber auch, um das Federelement und die Pendelklappe fertigungstechnisch als separate Bauteile fertigen zu können, ist das mindestens eine Federelement auswechselbar an dem Rückstellelement befestigt. Dadurch ist es möglich, das Federelement auszuwechseln, dieses aber auch im Produktionsprozess nach Herstellung der Pendelklappe an dieser zu befestigen. Ebenso ist es möglich zu entscheiden, ob ein Fensterfalzlüfter ein Federelement aufweisen soll oder nicht. Hierdurch wird nur ein Grundkörper des Volumenstrombegrenzers benötigt, der dann flexibel mit einem Federelement ausgestattet werden kann.Since the spring element is subject to wear, but also to manufacture the spring element and the pendulum flap manufacturing technology as separate components, the at least one spring element is replaceable attached to the return element. This makes it possible to replace the spring element, but this also in the production process after production of the pendulum flap to attach to this. It is also possible to decide whether a Fensterfalzlüfter should have a spring element or not. As a result, only one body of the flow restrictor is needed, which can then be flexibly equipped with a spring element.
Eine besonders vorteilhafte Verbindungsmöglichkeit zwischen Federelement und Rückstellelement besteht weitgehend darin, dass das mindestens eine Federelement mittels einer lösbaren Rastverbindung an dem Rückstellelement befestigt ist.A particularly advantageous possibility of connection between spring element and restoring element consists largely in that the at least one spring element is fastened by means of a releasable latching connection to the return element.
Um das Federelement an unterschiedliche Umgebungsbedingungen, sowohl hinsichtlich seiner Beständigkeit, wie beispielsweise Korrosionsbeständigkeit, als auch hinsichtlich seiner Federkraftwirkung, anpassen zu können, sieht die Erfindung weiterhin vor, dass das mindestens eine Federelement aus Metall oder Kunststoff besteht.To the spring element to different environmental conditions, both in terms of its durability, such as Corrosion resistance, as well as in terms of its spring force effect to be able to adapt, the invention further provides that the at least one spring element made of metal or plastic.

Aufgrund des Federelementes 15, das den Volumenstrombegrenzer 9 in seine Öffnungsstellung treibt, ist es möglich, den Fensterfalzlüfter 6 - anders als im Ausführungsbeispiel, in welcher er in einer waagerechten Position angeordnet ist - auch in einer senkrechten Position und damit in den senkrecht verlaufenden Abschnitten eines Fensterfalzes 5 anzuordnen. Damit kann der Fensterfalzlüfter 6 im Prinzip an jeder gewünschten Position des zwischen Blendrahmen 1 und Fensterflügel 2 umlaufenden Fensterfalzes angeordnet werden.
