Description

Die Erfindung betrifft eine Vorrichtung und ein Verfahren zur Regelung eines Luftstromes, mit einer Lüftungsöffnung, welche mittels zumindest eines Verschlusselementes zumindest teilweise verschließbar ist, wobei mittels zumindest einem ersten Betätigungselement die Stellung des Verschlusselementes in Abhängigkeit der Luftfeuchte beeinflussbar ist.The invention relates to a device and a method for controlling an air flow, with a ventilation opening, which is at least partially closed by means of at least one closure element, wherein by means of at least one first actuating element, the position of the closure element in response to the humidity can be influenced.

Aus der Praxis sind Vorrichtungen der eingangs genannten Art zur kontrollierten Belüftung von Gebäuden bekannt (siehe z.B. Dokument EP-0638775-A ). Bei diesen bekannten Vorrichtungen wird mittels eines zentral im Gebäude angeordneten maschinellen Lüfters ein konstanter Unterdruck im Inneren des Gebäudes aufrechterhalten. Über Vorrichtungen der eingangs genannten Art gelangt Frischluft in den Innenraum des Gebäudes. Durch die Stellung des Verschlusselementes wird die zugeführte Luftmenge entsprechend der relativen Luftfeuchte im Raum geregelt.From practice devices of the type mentioned for the controlled ventilation of buildings are known (see eg document EP-0638775-A ). In these known devices, a constant negative pressure is maintained in the interior of the building by means of a machine fan arranged centrally in the building. About devices of the type mentioned fresh air enters the interior of the building. By the position of the closure element, the supplied amount of air is controlled according to the relative humidity in the room.

Diese bekannte Vorrichtung weist jedoch den Nachteil auf, dass die Regelung des Luftstromes lediglich aufgrund der relativen Luftfeuchte nicht in allen Betriebsbedingungen ein zufriedenstellendes Raumklima sicherstellt. Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung anzugeben, mit welcher ein verbessertes Raumklima erzeugt werden kann.However, this known device has the disadvantage that the regulation of the air flow only due to the relative humidity does not ensure a satisfactory indoor climate in all operating conditions. The invention is therefore based on the object to provide a device with which an improved indoor climate can be generated.

Die Aufgabe wird erfindungsgemäß durch eine Vorrichtung gemäß Anspruch 1, ein Verfahren gemäß Anspruch 9 und eine Verwendung gemäß Anspruch 13 gelöst.The object is achieved by a device according to claim 1, a method according to claim 9 and a use according to claim 13.

Erfindungsgemäß wird eine Vorrichtung zur Regelung eines Luftstromes vorgeschlagen, bei welcher eine Lüftungsöffnung mittels zumindest eines Verschlusselementes zumindest teilweise verschließbar ist. Durch die Stellung des Verschlusselementes kann somit der freie Querschnitt der Lüftungsöffnung und damit der durch die Lüftungsöffnung hindurch tretende Luftstrom beeinflusst werden. Die Stellung des Verschlusselementes wird erfindungsgemäß durch zwei Betätigungselemente beeinflusst bzw. vorgegeben. Das erste Betätigungselement beeinflusst dabei die Stellung des Verschlusselementes in Abhängigkeit der Luftfeuchte. Das zweite Betätigungselement beeinflusst die Stellung des Verschlusselementes in Abhängigkeit der Lufttemperatur. Somit kann der in den Raum eintretende Luftstrom vergrößert werden, wenn die relative Luftfeuchte im Raum ansteigt. Sofern die relative Luftfeuchte sinkt, nimmt der dem Raum zugeführte Luftstrom wieder ab. In gleicher Weise kann der dem Raum zugeführte Luftstrom zunehmen, wenn die Raumtemperatur zu stark ansteigt. Wenn sowohl die Temperatur als auch die Feuchte ansteigen, überlagert sich die Wirkung beider Betätigungselemente, so dass eine besonders große Luftmenge zugeführt wird.According to the invention, a device for controlling an air flow is proposed, in which a ventilation opening is at least partially closable by means of at least one closure element. Due to the position of the closure element thus the free cross-section of the ventilation opening and so that the passing through the vent opening air flow can be influenced. The position of the closure element is inventively influenced or predetermined by two actuators. The first actuating element influences the position of the closure element depending on the humidity. The second actuating element influences the position of the closure element as a function of the air temperature. Thus, the airflow entering the room can be increased as the relative humidity in the room increases. If the relative humidity decreases, the air flow supplied to the room decreases again. In the same way, the air flow supplied to the room may increase if the room temperature rises too much. If both the temperature and the humidity increase, the effect of both actuators superimposed, so that a particularly large amount of air is supplied.

In einigen Ausführungsformen der Erfindung arbeiten sowohl das erste als auch das zweite Betätigungselement passiv. Dies bedeutet, dass die Stellung des Verschlusselementes ohne Zufuhr elektrischer Energie beeinflusst werden kann. Somit ist die erfindungsgemäße Vorrichtung über einen längeren Zeitraum wartungsfrei einsetzbar.In some embodiments of the invention, both the first and second actuators operate passively. This means that the position of the closure element can be influenced without the supply of electrical energy. Thus, the device according to the invention over a longer period of maintenance is used.

Die Lüftungsöffnung kann in einigen Ausführungsformen der Erfindung einen runden oder polygonalen Querschnitt aufweisen. Die Lüftungsöffnung kann eine Breite zwischen 50 und 175 mm aufweisen. In einigen Ausführungsformen der Erfindung kann die Lüftungsöffnung eine Höhe von 20 mm bis 175 mm aufweisen. In einigen Ausführungsformen der Erfindung können mehrere Lüftungsöffnungen vorgesehen sein, welche entweder durch ein einzelnes Verschlusselement zumindest teilweise verschließbar sind oder aber durch eine Mehrzahl von Verschlusselementen, wobei jeder Lüftungsöffnung zumindest ein Verschlusselement zugeordnet ist.The vent may in some embodiments of the invention have a round or polygonal cross-section. The ventilation opening may have a width between 50 and 175 mm. In some embodiments of the invention, the vent may have a height of 20 mm to 175 mm. In some embodiments of the invention, a plurality of ventilation openings may be provided which are at least partially closable either by a single closure element or by a plurality of closure elements, wherein each ventilation opening is associated with at least one closure element.

Das Verschlusselement kann in einigen Ausführungsformen der Erfindung eine Lüftungsklappe enthalten oder daraus bestehen. In anderen Ausführungsformen der Erfindung kann das Verschlusselement als Membran ausgebildet sein. Eine solche Membran erlaubt einen flächenbündigen Einbau der Vorrichtung, so dass das äußere Erscheinungsbild des Innenputzes bzw. der Fassade in geringerem Maße beeinträchtigt wird und die Montage von Vorhängen oder Rollos nicht behindert wird.The closure member may in some embodiments of the invention include or consist of a vent. In other embodiments of the invention, the closure element may be formed as a membrane. Such a membrane allows a flush installation of the device, so that the external appearance of the interior plaster or the facade in lesser Dimensions are affected and the installation of curtains or blinds is not hindered.

In einigen Ausführungsformen der Erfindung kann vorgesehen sein, dass am Verschlusselement zumindest ein erstes Federelement angreift, mit welchem das Verschlusselement in eine geöffnete Stellung bringbar ist und das erste und/oder zweite Betätigungselement dazu eingerichtet ist, der Federkraft des ersten Federelements entgegenzuwirken. Auf diese Weise wird bei Ausfall des ersten und des zweiten Betätigungselementes das Verschlusselement in eine geöffnete Stellung gebracht, so dass eine hinreichende Belüftung des Raumes sichergestellt ist. Sofern die Luftfeuchte und/oder die Lufttemperatur einen Wert annimmt, bei welchem ein Betätigungselement das Verschlusselement zumindest teilweise schließt, wirkt die vom Betätigungselement aufgebrachte Schließkraft der Federkraft des ersten Federelementes entgegen, so dass das Verschlusselement geschlossen und der Luftstrom reduziert wird.In some embodiments of the invention it can be provided that the closure element engages at least a first spring element, with which the closure element can be brought into an open position and the first and / or second actuating element is adapted to counteract the spring force of the first spring element. In this way, the closure element is brought into an open position in case of failure of the first and the second actuating element, so that a sufficient ventilation of the room is ensured. If the humidity and / or the air temperature assumes a value at which an actuating element at least partially closes the closing element, the closing force exerted by the actuating element counteracts the spring force of the first spring element, so that the closing element is closed and the air flow is reduced.

In einigen Ausführungsformen kann das erste Betätigungselement zumindest eine Kunstfaser enthalten oder daraus bestehen. In anderen Ausführungsformen der Erfindung kann eine Mehrzahl von Kunstfasern eingesetzt werden, welche parallel zueinander verlaufen. Die Anzahl der Kunstfasern kann in einigen Ausführungsformen etwa 4 bis etwa 15 betragen. Auf diese Weise wird die bereitgestellte Schließkraft des ersten Betätigungselementes erhöht. Das Material der Kunstfaser ist dergestalt ausgewählt, dass sich die Kunstfaser bei einer Zunahme der relativen Luftfeuchte ausdehnt und bei einer Abnahme der Luftfeuchte zusammenzieht. Auf diese Weise kann sichergestellt werden, dass die vorgeschlagene Vorrichtung ohne Zufuhr elektrischer Energie auf eine sich ändernde Luftfeuchte reagiert und auf diese Weise viele Jahre wartungsfrei betrieben werden kann. In einigen Ausführungsformen der Erfindung kann die Kunstfaser Polyester enthalten oder daraus bestehen.In some embodiments, the first actuator may include or consist of at least one synthetic fiber. In other embodiments of the invention, a plurality of synthetic fibers can be used, which run parallel to each other. The number of synthetic fibers may be about 4 to about 15 in some embodiments. In this way, the provided closing force of the first actuating element is increased. The material of the synthetic fiber is selected such that the synthetic fiber expands as the relative humidity increases and contracts as the humidity decreases. In this way it can be ensured that the proposed device reacts without supplying electrical energy to a changing humidity and can be operated in this way many years maintenance-free. In some embodiments of the invention, the synthetic fiber may contain or consist of polyester.

In einigen Ausführungsformen der Erfindung kann das zweite Betätigungselement als passives Dehnelement ausgeführt sein, welches einen Dehnstoff enthält. Der Dehnstoff wird dergestalt ausgewählt, dass dieser sich bei steigender Temperatur ausdehnt und bei fallender Temperatur zusammenzieht. Dadurch kann die vorgeschlagene Vorrichtung den Luftstrom auch in Abhängigkeit wechselnder Temperaturen regeln, ohne dass es der Zufuhr von Hilfsenergie bedarf, beispielsweise zum Antrieb eines elektrischen Stellelementes oder einer elektronischen Regelung. Der Dehnstoff kann Öl, Wachs, Silikon oder Hartparaffin enthalten.In some embodiments of the invention, the second actuator may be implemented as a passive expansion element containing an expanding material. The expansion material is selected such that it expands with increasing temperature and contracts with decreasing temperature. As a result, the proposed device, the air flow in dependence regulate changing temperatures without the need for the supply of auxiliary power, for example, to drive an electric actuator or electronic control. The wax can contain oil, wax, silicone or hard paraffin.

In einigen Ausführungsformen kann das zweite Betätigungselement einen Balg aus einem Polymer, einem Gummi oder einem Metall enthalten, welcher mit dem Dehnstoff gefüllt ist. Auf diese Weise kann eine größere Menge des Dehnstoffes in das Verschlusselement eingebracht werden, so dass eine größere Öffnungskraft bereitgestellt wird. Durch die größere Masse des Dehnstoffes reagiert die Temperaturregelung verzögert, so dass sich eine Regelung mit integrierender Charakteristik ergibt.In some embodiments, the second actuator may include a bladder of a polymer, a rubber, or a metal filled with the wax. In this way, a larger amount of the expansion material can be introduced into the closure element, so that a greater opening force is provided. Due to the larger mass of the expansion material, the temperature control reacts with a delay, resulting in a control with an integrating characteristic.

In einigen Ausführungsformen der Erfindung kann die Vorrichtung eine Mehrzahl von Verschlusselementen aufweisen, wobei zumindest ein Verschlusselement an der Rauminnenseite und ein Verschlusselement an der Außenseite des Raumes angeordnet ist. Hierdurch kann die Regelung so ausgestaltet sein, dass sowohl die Innen- als auch die Außentemperatur berücksichtigt werden. Beispielsweise kann das äußere Verschlusselement die Lüftungsöffnung zumindest teilweise verschließen, wenn die Temperatur oberhalb eines vorgebbaren Grenzwertes ansteigt. Auf diese Weise wird verhindert, dass bei einem Anstieg der Raumtemperatur warme Umgebungsluft in den Raum geführt wird, was zu einem weiteren Anstieg der Innentemperatur führen würde. In anderen Ausführungsformen der Erfindung kann bei zumindest einem der beiden Verschlusselemente das erste und/oder das zweite Betätigungselement auch entfallen.In some embodiments of the invention, the device may comprise a plurality of closure elements, wherein at least one closure element is arranged on the interior side of the room and a closure element on the outside of the room. As a result, the control can be designed such that both the inside and the outside temperature are taken into account. For example, the outer closure element can at least partially close the ventilation opening when the temperature rises above a predefinable limit value. In this way it is prevented that when the room temperature rises warm ambient air is led into the room, which would lead to a further increase in the internal temperature. In other embodiments of the invention, the first and / or the second actuating element may also be omitted in at least one of the two closure elements.

In einigen Ausführungsformen der Erfindung kann das erste Betätigungselement und/oder das zweite Betätigungselement mittels eines zweiten Federelementes an einem unbeweglichen Teil der Vorrichtung befestigt sein. Auf diese Weise kann das erste Betätigungselement oder das zweite Betätigungselement eine Kraft auf das erste Federelement ausüben, um das Verschlusselement von einer geöffneten in eine geschlossene Stellung zu überführen. Das jeweils nicht am Schließvorgang bzw. Öffnungsvorgang beteiligte Betätigungselement wird dann über das zweite Federelement freigegeben, so dass dieses die Bewegung des Verschlusselements nicht behindert.In some embodiments of the invention, the first actuating element and / or the second actuating element may be fastened by means of a second spring element to an immovable part of the device. In this way, the first actuating element or the second actuating element exert a force on the first spring element in order to transfer the closure element from an open to a closed position. The respectively not involved in the closing or opening operation actuator is then on the second Released spring element, so that this does not hinder the movement of the closure element.

In einigen Ausführungsformen der Erfindung kann die beschriebene Vorrichtung dazu eingesetzt werden, die dem Raum zugeführte Menge an Frischluft zu regeln. Zu diesem Zweck kann die Vorrichtung in einer Außenfassade und/oder einem Rolladenkasten und/oder einem Fensterrahmen integriert sein, um die durch die Lüftungsöffnung von außen in den Raum geführte Frischluftmenge zu beeinflussen, so dass die Raumtemperatur und/oder die Feuchte innerhalb eines vorgebbaren Bereiches gehalten wird.In some embodiments of the invention, the apparatus described may be used to control the amount of fresh air supplied to the room. For this purpose, the device may be integrated in an outer facade and / or a roller shutter box and / or a window frame in order to influence the amount of fresh air introduced into the room through the ventilation opening, so that the room temperature and / or the humidity within a predeterminable range is held.

Alternativ oder kumulativ kann die beschriebene Vorrichtung in einigen Ausführungsformen der Erfindung auch in Verbindung mit einer Abluftleitung eingesetzt werden, um auf diese Weise die über einen Lüftungsschacht und/oder einen maschinellen Lüfter aus dem Raum entfernte Luftmenge so zu beeinflussen, dass Temperatur und/oder Feuchte innerhalb eines vorgebbaren Bereiches gehalten werden. Durch die erfindungsgemäße Vorrichtung kann der Luftaustausch des Raumes lastabhängig geregelt werden, d.h. bei Zufuhr von Wärme und/oder Feuchte steigt der Luftaustausch an, bis die Auswirkungen des Wärme- und/oder Feuchteeintrags kompensiert sind.Alternatively or cumulatively, in some embodiments of the invention, the described device can also be used in conjunction with an exhaust air line in order to influence the amount of air removed from the room via a ventilation shaft and / or a mechanical fan in such a way that temperature and / or humidity be kept within a predetermined range. By the device according to the invention, the air exchange of the space can be regulated depending on the load, i. When heat and / or humidity is supplied, the air exchange increases until the effects of the heat and / or moisture input are compensated.

Figur 1 zeigt eine Explosionszeichnung einer Ausführungsform der erfindungsgemäßen Vorrichtung. Die Vorrichtung enthält einen Rahmen 100. In den Rahmen 100 ist eine Aussparung 110 angeordnet, welche zur Aufnahme der Federelemente und Betätigungselemente dient und welche zumindest teilweise den Querschnitt der Lüftungsöffnung 25 bildet. Der Rahmen 100 kann in einigen Ausführungsformen der Erfindung aus einem Metall oder einer Legierung gefertigt sein, beispielsweise einer Aluminiumlegierung. In anderen Ausführungsformen der Erfindung kann der Rahmen 100 aus einem Kunststoffmaterial hergestellt sein, beispielsweise einem Thermoplast. Der Rahmen kann in einigen Ausführungsformen der Erfindung durch Spritzgießen oder ein Stranggussverfahren erhalten werden. FIG. 1 shows an exploded view of an embodiment of the device according to the invention. The device includes a frame 100. In the frame 100 is a recess 110 which serves to receive the spring elements and actuators and which at least partially forms the cross section of the vent opening 25. The frame 100, in some embodiments of the invention, may be made of a metal or alloy, such as an aluminum alloy. In other embodiments of the invention, the frame 100 may be made of a plastic material, such as a thermoplastic. The frame can be obtained in some embodiments of the invention by injection molding or a continuous casting process.

Der Rahmen 100 weist eine erste Seite 101 auf, welche bei Einsatz der Vorrichtung 10 dem zu belüftenden Raum zugewandt ist. Zu diesem Zweck kann die erste Seite 101 dekorativ gestaltet sein, um sich gestalterischen Vorgaben des zu belüftenden Raumes oder des angrenzenden Bauteils anzupassen.The frame 100 has a first side 101 which, when the device 10 is used, faces the space to be ventilated. For this purpose, the first page 101 may be decorative designed to adapt to design specifications of the space to be ventilated or the adjacent component.

Weiterhin weist der Rahmen 100 eine zweite Seite 102 auf, an welcher in einigen Ausführungsformen der Erfindung Befestigungselemente angeordnet sein können. In anderen Ausführungsformen der Erfindung kann eine erste Rahmen 100 mit der zweiten Seite 102 an einem zweiten Rahmen 115 befestigt sein, so dass sich ein symmetrischer Aufbau der erfindungsgemäßen Vorrichtung ergibt. In wiederum einer anderen Ausführungsform der Erfindung kann zwischen dem ersten und dem zweiten Rahmen ein Bauteil eines Gebäudes angeordnet sein, beispielsweise ein Fensterrahmen oder eine Mauer. Der zweite Rahmen 115 ist jedoch optional und kann in anderen Ausführungsformen der Erfindung auch entfallen. Die Funktion der erfindungsgemäßen Vorrichtung wird daher anhand des ersten Rahmen 100 erläutert, wobei der zweite Rahmen 115 die identischen Merkmale und den identischen Aufbau zur ersten Rahmen 100 aufweisen kann. In einigen Ausführungsformen der Erfindung kann der zweite Rahmen weniger oder andere Elemente aufweisen als der erste Rahmen.Furthermore, the frame 100 has a second side 102 on which fastening elements can be arranged in some embodiments of the invention. In other embodiments of the invention, a first frame 100 with the second side 102 may be attached to a second frame 115, resulting in a symmetrical structure of the device according to the invention. In yet another embodiment of the invention may be arranged between the first and the second frame, a component of a building, such as a window frame or a wall. However, the second frame 115 is optional and may be omitted in other embodiments of the invention. The function of the device according to the invention will therefore be explained with reference to the first frame 100, wherein the second frame 115 may have the identical features and the identical construction to the first frame 100. In some embodiments of the invention, the second frame may have fewer or different elements than the first frame.

In der Aussparung 110 ist zumindest ein erstes Federelement angeordnet. Das erste Federelement weist einen Steg 120 aus einem federnden Material auf, welcher mittels elastischer Elemente 121 am Rahmen 100 befestigt ist. Der Steg 120 kann beispielsweise aus einem Kunststoffmaterial gefertigt sein. In anderen Ausführungsformen der Erfindung kann der Steg 120 einen Federstahl enthalten oder daraus bestehen. Der Steg 120 und die elastischen Elemente 121 wirken zusammen, so dass die Federelemente 120 in unbelastetem Zustand beabstandet zueinander angeordnet sind. Somit bewegen sich die Stege 120 im unbelasteten Zustand aufgrund der Federkraft zu den Rändern des Rahmens 100. Dadurch bildet sich zwischen den Stegen 120 ein freier Querschnitt aus.In the recess 110 at least a first spring element is arranged. The first spring element has a web 120 made of a resilient material, which is fastened to the frame 100 by means of elastic elements 121. The web 120 may be made of a plastic material, for example. In other embodiments of the invention, the web 120 may include a spring steel or consist of. The web 120 and the elastic elements 121 cooperate, so that the spring elements 120 are arranged spaced from each other in the unloaded state. Thus, the webs 120 move in the unloaded state due to the spring force to the edges of the frame 100. This forms between the webs 120, a free cross section.

Parallel zu den Stegen 120 ist der erste Längsabschnitt 220 des ersten Betätigungselementes 200 kraftschlüssig angeordnet. Der erste Längsabschnitt 220 geht über einen Knick 230 in einen zweiten Längsabschnitt 210 über. Die Längsabschnitte 210 und/oder 220 enthalten zumindest eine Kunstfaser, welche eine Längenänderung in Abhängigkeit der relativen Luftfeuchte zeigt. Das erste Betätigungselement 200 ist an seinen Enden 240 an einem Befestigungselement 105 angeschlagen, welches am Rahmen 100 befestigt ist oder ein integraler Bestandteil des Rahmens 100 ist. In einigen Ausführungsformen der Erfindung kann die Befestigung mittels zweiten Federelementen 240 erfolgen. Die Federelemente können ein Elastomer und/oder einen Federstahl enthalten oder daraus bestehen.Parallel to the webs 120, the first longitudinal section 220 of the first actuating element 200 is arranged non-positively. The first longitudinal section 220 merges via a bend 230 into a second longitudinal section 210. The longitudinal sections 210 and / or 220 contain at least one synthetic fiber, which shows a change in length as a function of the relative humidity. The first actuator 200 is hinged at its ends 240 to a fastener 105 which is attached to the frame 100 or is an integral part of the frame 100. In some embodiments of the invention, the attachment may be by means of second spring elements 240. The spring elements may contain or consist of an elastomer and / or a spring steel.

Bei geringer relativer Luftfeuchte verkürzt sich der Längsabschnitt 220 des ersten Betätigungselementes 200, so dass der parallel zum ersten Längsabschnitt 220 angeordnete Steg 120 in eine weniger gekrümmte Stellung gezogen wird. Durch die symmetrische Anordnung von zwei ersten Betätigungselementen 200 und zwei Stegen 120 können die Stege 120 in eine näherungsweise parallele Stellung zueinander gebracht werden, so dass der von den Stegen 120 eingeschlossene Zwischenraum minimal wird. Da der Zwischenraum zwischen den Stegen 120 den Querschnitt der Lüftungsöffnung 25 bestimmt, kann die Lüftungsöffnung 25 bei geringer relativer Feuchte minimiert werden. In einigen Ausführungsformen der Erfindung kann der Querschnitt der Lüftungsöffnung auch bis auf Null reduziert werden, so dass kein Luftaustausch durch die Lüftungsöffnung 25 erfolgt.At low relative humidity, the longitudinal section 220 of the first actuating element 200 is shortened so that the web 120 arranged parallel to the first longitudinal section 220 is pulled into a less curved position. The symmetrical arrangement of two first actuators 200 and two webs 120, the webs 120 can be brought into an approximately parallel position to each other, so that the trapped by the webs 120 gap is minimal. Since the gap between the webs 120 determines the cross-section of the vent opening 25, the vent opening 25 can be minimized at low relative humidity. In some embodiments of the invention, the cross-section of the ventilation opening can also be reduced to zero, so that no air exchange takes place through the ventilation opening 25.

Bei zunehmender relativer Feuchte wird zumindest die Länge des ersten Längsabschnittes 210 des ersten Betätigungselementes 200 größer. Hierdurch vergrößert sich die Krümmung der Stege 120, so dass der zwischen zwei Stegen 120 eingeschlossene Zwischenraum und damit der Querschnitt der Lüftungsöffnung 25 größer wird.As the relative humidity increases, at least the length of the first longitudinal section 210 of the first actuating element 200 becomes larger. This increases the curvature of the webs 120, so that the enclosed between two webs 120 intermediate space and thus the cross section of the vent opening 25 is larger.

Um die Lüftungsöffnung 25 zumindest teilweise zu verschließen, steht ein Verschlusselement 20 zur Verfügung. Das Verschlusselement 20 ist in der dargestellten Ausführungsform als Membran ausgebildet, welche in ihrem mittleren Bereich einen die Lüftungsöffnung 25 bildenden Schlitz aufweist. Weiterhin weist die Membran 20 mehrere Falten 24 auf. Die Membran 20 kann in einigen Ausführungsformen der Erfindung aus einem Kunststoffmaterial bestehen. Das Material kann elastisch ausgeführt sein, um eine freie Beweglichkeit der Membran 20 bei der Bewegung der Stege 120 zu gewährleisten. Beispielsweise kann die Membran 20 einem Gummi oder ein Elastomer enthalten oder daraus bestehen. Das Material der Membran 20 kann daneben mit weiteren Materialien gefüllt sein, welche das äußere Erscheinungsbild oder die mechanischen Eigenschaften oder die thermischen Eigenschaften der Membran 20 beeinflussen. Die Begrenzungsränder des Schlitzes sind zumindest abschnittsweise an den Stegen 120 befestigt. Der äußere Rand der Membran ist an der äußeren Begrenzungslinie 111 der Aussparung 110 befestigt. Auf diese Weise kann das Verschlusselement 20 den größten Teil der Aussparung 110 im Rahmen 100 verschließen.In order to at least partially close the ventilation opening 25, a closure element 20 is available. The closure element 20 is formed in the illustrated embodiment as a membrane, which has a ventilation opening 25 forming slot in its central region. Furthermore, the membrane 20 has a plurality of folds 24. The membrane 20 may be made of a plastic material in some embodiments of the invention. The material can be designed to be elastic in order to ensure free mobility of the membrane 20 during the movement of the webs 120. For example, the membrane 20 may contain or consist of a rubber or an elastomer. The material of the membrane 20 may also be filled with other materials that affect the external appearance or mechanical properties or thermal properties of the membrane 20. The boundary edges of the slot are at least partially attached to the webs 120. The outer edge of the membrane is attached to the outer boundary line 111 of the recess 110. In this way, the closure element 20 can close most of the recess 110 in the frame 100.

In Abhängigkeit der Bewegung der Stege 120, welche durch deren Federkraft und der feuchteabhängigen Längsausdehnung des ersten Abschnittes 220 des ersten Betätigungselementes 200 kontrolliert wird, wird die Lüftungsöffnung 25 durch die Membran 20 in größerem oder kleinerem Umfang freigegeben.Depending on the movement of the webs 120, which is controlled by their spring force and the moisture-dependent longitudinal extent of the first portion 220 of the first actuating element 200, the vent opening 25 is released by the membrane 20 to a greater or lesser extent.

Um weiterhin eine temperaturabhängige Regelung des durch die Lüftungsöffnung 25 hindurch tretenden Luftstroms zu ermöglichen, kann in einigen Ausführungsformen der Erfindung vorgesehen sein, dass ein zweites Betätigungselement auf die Lage der Stege 120 einwirkt, um auf diese Weise die Größe der Lüftungsöffnung 25 zu beeinflussen. Im dargestellten Ausführungsbeispiel enthält die Vorrichtung zwei zweite Betätigungselemente 245. Das zweite Betätigungselement 245 enthält einen Balg aus einem elastischen Material, beispielsweise einem Polymer oder einem Gummi. Der Balg weist eine im Wesentlichen zylindrische Grundform auf. Im Innenraum des Zylinders ist ein Dehnstoff integriert. Der Dehnstoff kann Öl, Wachs, Silikon oder Hartparaffin enthalten. Der Dehnstoff sorgt für eine Längenänderung des Balges mit steigender Temperatur und einer Verkürzung des Balges bei fallender Temperatur. Auf diese Weise kann eine in Längsrichtung auf die Stege 120 wirkende Kraft ausgeübt werden, welche zu einer Zunahme der Krümmung der Stege führt. Hierdurch wird die Lüftungsöffnung 25 bei steigender Temperatur vergrößert und bei fallender Temperatur verkleinert.In order to further enable a temperature-dependent regulation of the air flow passing through the ventilation opening 25, in some embodiments of the invention it can be provided that a second actuating element acts on the position of the webs 120, in this way influencing the size of the ventilation opening 25. In the illustrated embodiment, the device includes two second actuators 245. The second actuator 245 includes a bellows made of an elastic material, such as a polymer or a rubber. The bellows has a substantially cylindrical basic shape. In the interior of the cylinder an expansion material is integrated. The wax can contain oil, wax, silicone or hard paraffin. The expansion material ensures a change in length of the bellows with increasing temperature and a shortening of the bellows with decreasing temperature. This way you can a force acting in the longitudinal direction on the webs 120 force are exerted, which leads to an increase in the curvature of the webs. As a result, the ventilation opening 25 is increased with increasing temperature and reduced with decreasing temperature.

Bei hoher Temperatur und geringer Luftfeuchte, wenn der Dehnstoff im Balg 245 eine Vergrößerung der Lüftungsöffnung 25 bewirkt und das erste Betätigungselement 200 eine Verkleinerung der Lüftungsöffnung 25 bewirken würde, kann das erste Betätigungselement 200 über die Federn 240 nachgeben und trotz niedriger Luftfeuchte die Lüftungsöffnung 25 zumindest teilweise freigeben.At high temperature and low humidity, when the expansion material in the bellows 245 causes an enlargement of the ventilation opening 25 and the first actuator 200 would cause a reduction of the ventilation opening 25, the first actuator 200 can give over the springs 240 and despite low air humidity, the ventilation opening 25 at least partially release.

Sofern die Vorrichtung symmetrisch aufgebaut ist, kann diese einen zweiten Rahmen 115 enthalten, dessen Öffnung von einer zweiten Membran 21 verschlossen wird. In einigen Ausführungsformen der Erfindung kann der zweite Rahmen 115 mit der zweiten Membran 21 an der Außenseite des Gebäudes angeordnet und an die gestalterischen Anforderungen der Gebäudeaußenseite angepasst sein. Weiterhin kann das Verhalten der ersten und zweiten Betätigungselemente im zweiten Rahmen 115 vom Verhalten der ersten und zweiten Betätigungselemente im ersten Rahmen 100 abweichen, so dass die Luftzufuhr in den mit der Vorrichtung ausgestatteten Raum weiter optimiert wird. Im dargestellten Ausführungsbeispiel enthält der zweite Rahmen 115 nur ein erstes Betätigungselement 200. Das zweite Betätigungselement 245 ist nur im ersten Rahmen 100 vorgesehen.If the device is constructed symmetrically, this may include a second frame 115, the opening of which is closed by a second membrane 21. In some embodiments of the invention, the second frame 115 may be arranged with the second membrane 21 on the outside of the building and adapted to the design requirements of the building exterior. Furthermore, the behavior of the first and second actuators in the second frame 115 may differ from the behavior of the first and second actuators in the first frame 100, so that the air supply to the space provided with the device is further optimized. In the illustrated embodiment, the second frame 115 includes only a first actuator 200. The second actuator 245 is provided only in the first frame 100.

Figur 2 zeigt die Innenansicht einer Vorrichtung 10 gemäß der vorliegenden Erfindung in geschlossenem Zustand. In Figur 2 ist eine Aufsicht auf den ersten Rahmen 100 mit der daran befestigten Membran 20 dargestellt. Die in Figur 1 dargestellten Stege 120 und das erste Betätigungselement 200 ist von der Membran 20 verdeckt. FIG. 2 shows the interior view of a device 10 according to the present invention in the closed state. In FIG. 2 a plan view of the first frame 100 with the membrane 20 attached thereto is shown. In the FIG. 1 illustrated webs 120 and the first actuating element 200 is covered by the membrane 20.

Im dargestellten Betriebszustand ist die Lüftungsöffnung 25 nahezu vollständig geschlossen bzw. auf einen minimalen Luftstrom eingestellt. Dies wird dadurch erreicht, dass die Stege 120 nahezu parallel zueinander angeordnet sind. Die Falten 24 der Membran 20 gestatten dabei eine freie Beweglichkeit der Membran, so dass diese die Lüftungsöffnung verdecken kann.In the illustrated operating state, the ventilation opening 25 is almost completely closed or adjusted to a minimum air flow. This is achieved in that the webs 120 are arranged almost parallel to each other. The folds 24 of the membrane 20 allow a free movement of the membrane, so that it can cover the ventilation opening.

Figur 3 zeigt die Vorrichtung gemäß Figur 2 in einem geöffneten Zustand. Dies kann entweder bei einem Anstieg der relativen Luftfeuchte über das erste Betätigungselement und/oder bei einem Anstieg der Temperatur durch das zweite Betätigungselement verursacht sein. In jedem Fall führt eine zunehmende Krümmung der Stege 120 zu einer Vergrößerung des Abstandes der Stege 120 und damit zur Ausbildung einer größeren Lüftungsöffnung 25, über welche die Luft in den Raum einströmen kann bzw. diesen über eine Lüftungsleitung verlassen kann. Die Falten 24 der Membran 20 gewährleisten auch in diesem Fall die freie Beweglichkeit, so dass die Membran 20 den Bewegungen der Stege 120 folgen kann. FIG. 3 shows the device according to FIG. 2 in an open state. This can be caused either by an increase in the relative humidity over the first actuator and / or an increase in the temperature by the second actuator. In any case, an increasing curvature of the webs 120 leads to an increase in the distance of the webs 120 and thus to the formation of a larger ventilation opening 25 through which the air can flow into the room or leave it via a ventilation duct. The folds 24 of the membrane 20 also ensure freedom of movement in this case, so that the membrane 20 can follow the movements of the webs 120.

Selbstverständlich ist die Erfindung nicht auf die in den Figuren dargestellten Ausführungsformen beschränkt. Die vorstehende Beschreibung ist daher nicht als beschränkend, sondern als erläuternd anzusehen. Die nachfolgenden Ansprüche sind so zu verstehen, dass ein genanntes Merkmal in zumindest einer Ausführungsform der Erfindung vorhanden ist. Dies schließt die Anwesenheit weiterer Merkmale nicht aus. Sofern die Ansprüche und die vorstehende Beschreibung "erste" und "zweite" Merkmale definieren, so dient diese Bezeichnung der Unterscheidung zweier gleichartiger Merkmale, ohne eine Rangfolge festzulegen.Of course, the invention is not limited to the embodiments shown in the figures. The above description is therefore not to be considered as limiting, but as illustrative. The following claims are to be understood as meaning that a named feature is present in at least one embodiment of the invention. This does not exclude the presence of further features. If the claims and the above description define "first" and "second" features, then this term serves to distinguish two similar features without prioritizing them.
