Description

Die Erfindung bezieht sich auf einen Insektenschutz für Gebäudeöffnungen, insbesondere Fenster, mit einem biegsamen Netz aus wetterfestem, verrottungsfestem Material, das nach Art einer Jalousie in der Gebäudeöffnung auf- und abbewegbar, und zwischen einer hin- und hergehend faltenbildenden Stellung, in der das Netz die Gebäudeöffnung zumindest teilweise freigibt, und einer gestreckten Stellung, in der das Netz die Gebäudeöffnung abschließt, auf- und abbewegbar ist, und mit einer am Netz befestigten horizontalen Fallstange. Ferner bezieht sich die Erfindung auf ein Verfahren zur Herstellung eines solchen Insektenschutzes.The invention relates to an insect screen for building openings, in particular windows, with a flexible network of weatherproof, rot-proof material that can be moved up and down in the manner of a blind in the building opening, and between a reciprocating fold-forming position in which the network the building opening is at least partially exposed, and an extended position, in which the network closes the building opening, can be moved up and down, and with a horizontal drop bar attached to the network. The invention further relates to a method for producing such an insect screen.

Zur Abdichtung von Gebäudeöffnungen, insbesondere Fenstern, gegen einfliegende Insekten, wie Fliegen, Stechmücken, Wespen usw., ist es bekannt, die Gebäudeöffnung mit einem Netz zu verschließen. Zumeist ist dieses Netz an einem starren Rahmen befestigt, der vor der Gebäudeöffnung angebracht werden kann. Ein derartiger Insektenschutz ist bei entsprechend sorgfältiger Montage zwar wirksam, jedoch nicht überall problemlos anwendbar, z.B. dort nicht, wo die Gebäudeöffnung schwer zugänglich ist oder ihre Außenfläche profiliert ist, z.B. durch Wetterschenkel, Gesimse usw.To seal building openings, in particular windows, against flying insects, such as flies, mosquitoes, wasps, etc., it is known to close the building opening with a net. This network is usually attached to a rigid frame that can be attached in front of the building opening. Such insect protection is effective when properly assembled, but it cannot be used anywhere without problems, e.g. not where the building opening is difficult to access or the outside surface is profiled, e.g. through weatherboard, cornices etc.

Aus der FR-PS 1 499 994 ist ein Insektenschutz bekannt geworden, der nach Art eines Vorhanges vor der Gebäudeöffnung heruntergelassen werden kann. Zur Erzielung einer befriedigenden Dichtung gegen Insekten müßten die Seitenränder des Vorhanges nach dem Herunterlassen desselben dichtend an die Gebäudefrontwand angedrückt und in dieser Lage gehalten werden. Hiezu sind gesonderte Befestigungsmittel erforderlich, die in ihrer Bedienung hinderlich und nicht immer zuverlässig sind.From FR-PS 1 499 994 an insect protection has become known which can be lowered like a curtain in front of the building opening. To achieve a satisfactory seal against insects, the side edges of the curtain would have to be pressed tightly against the front wall of the building after it had been lowered and held in this position. Separate fasteners are required for this which are cumbersome to operate and are not always reliable.

Es wurde auch versucht, einen Insektenschutz nach Art eines Rollvorhanges auszubilden, der im aufgerollten Zustand in einem am Fenstersturz befestigten Einbaukasten Platz findet und in die Gebäudeöffnung an zu beiden Seiten angebrachten Schienenführungen abdichtend heruntergezogen werden kann. Eine-solche Ausführung ist mit einem verhältnismäßig hohen Kostenaufwand verbunden. Eine ähnliche Konstruktion ist auch aus der FR-PS 1 574 013 bekannt geworden, wobei die Seitenränder des Netzes mittels an ihnen befestigter metallischer Gleitknöpfe in in der Gebäudeöffnung befestigten, im wesentlichen U-förmigen Führungsschienen geführt sind, wobei die Netzränder in die Öffnung des U-Profils eingreifen. Diese Konstruktion ist aufwendig und gewährleistet zwischen den Gleitknöpfen immer noch Restspalte, durch die Insekten hindurchschlüpfen können. Außerdem behindern die Gleitknöpfe eine enge Zusammenlegung des Netzes in seiner Offenstellung, so-daß im aufgezogenen, zusammengelegten Zustand des Netzes dieses ein voluminöses Paket bildet, das den Lichteinfall durch die Gebäudeöffnung beeinträchtigt.Attempts have also been made to design an insect screen in the manner of a rolling curtain, which, when rolled up, can be stored in a built-in box attached to the lintel and can be pulled down sealingly into the building opening on rail guides on both sides. Such an implementation is associated with a relatively high cost. A similar construction is also known from FR-PS 1 574 013, the side edges of the network being guided by means of metallic sliding buttons attached to them in substantially U-shaped guide rails fastened in the building opening, the network edges being guided into the opening of the U - Intervene profiles. This construction is complex and still ensures that there are residual gaps between the sliding buttons through which insects can slip. In addition, the sliding buttons hinder a tight collapse of the net in its open position, so that when the net is pulled open, it forms a voluminous package that interferes with the incidence of light through the opening of the building.

Die Erfindung geht nun aus von einem Insektenschutz der eingangs geschilderten Art und setzt sich zur Aufgabe, die Nachteile der vorstehend beschriebenen bekannten Konstruktionen zu vermeiden und einen Insektenschutz für Gebäudeöffnungen zu schaffen, mit welchem die Gebäudeöffnung bei geringem Aufwand einfach und verläßlich abgedichtet wird, wobei dieser Insektenschutz universell einsetzbar ist. Die Erfindung löst diese Aufgabe dadurch, daß die Breite des unverformten Netzes größer ist als die lichte Breite der Gebäudeöffnung, daß das Netz durch horizontale Faltkanten harmonikaartig fixiert ist und daß die Seitenränder des Netzes gegenüber dem zwischen ihnen liegenden Mittelteil des Netzes abgebogen sind und an den-in der Netzebene liegenden, quer zur Netzebene verlaufenden Abschnitten der Seitenflächen der Gebäudeöffnung elastish anliegen, wobei die Fallstange kürzer ist als die Breite des Netzes. Das biegsame Netz ermöglicht durch seine harmonikaartig fixierte Faltung, daß das Netz mit seinen Seitenrändern bei der Auf- und Abbewegung an den Seitenflächen der Gebäudeöffnung streift bzw. schleifend anliegt, ohne daß für die Auf- bzw. Abbewegung des Netzes bei der Freigabe bzw. beim Verschluß der Gebäudeöffnung übermäßiger Kraftaufwand notwendig ist. In der Verschlußstellung des jalousieartigen Insektenschutzes ergibt sich eine vollkommene Abdichtung der Gebäudeöffnung, ohne daß die Luft- und Lichtdurchlässigkeit verloren geht. Der Aufwand für den erfindungsgemäßen Insektenschutz ist etwa gleich einem einer gewöhnlichen Jalousie und daher wesentlich geringer als bei den eingangs beschriebenen bekannten Konstruktionen. Ferner ist die Erfindung für jedwede Gebäudeöffnung anwendbar, solange nur die mit den Seitenrändern des Ndzes zusammenwirkenden Abschnitte der Gebäudeöffnungsseitenflächen einigermaßen eben sind. Geringen Unebenheiten paßt sich das biegsame Netz elastisch an. Dadurch wird auch der Vorteil erzielt, daß der erfindungsgemäße Insektenschutz unabhängig ist von der Einhaltung genauer Maßtoleranzen, da es innerhalb gewisser Grenzen nichts ausmacht, wenn die Seitenränder des Netzes bei der Auf- bzw. Abbewegung des Netzes mehr oder weniger abgebogen an den abzudichtenden Abschnitten der Seitenflächen der Gebäudeöffnung, z.B. an den Stockinnenflächen, anliegen, solange nur die Bedingung gewahrt bleibt, daß der Netzseitenrand an mit ihm zusammenwirkenden Abschnitt der Seitenfläche der Gebäudeöffnung streift und damit die Dichtwirkung sichert. Es genügt daher, für einen bestimmten Breitenbereich zu verschließender Gebäudeöffnungen eine gewisse Normbreite des zu verwendenden Netzes auf Lager zu halten, wodurch teure Maßanfertigungen im allgemeinen vermeidbar sind.The invention is now based on an insect screen of the type described at the outset and sets itself the task of avoiding the disadvantages of the known constructions described above and of creating an insect screen for building openings with which the building opening is sealed easily and reliably with little effort, the latter Insect protection can be used universally. The invention solves this problem in that the width of the undeformed network is greater than the clear width of the building opening, that the network is fixed in a harmonious manner by means of horizontal folded edges and that the side edges of the network are bent relative to the central part of the network between them and to the - Elastic sections of the side faces of the building opening lying at right angles to the network plane The drop bar is shorter than the width of the net. The flexible network, thanks to its harmonica-like fixed fold, allows the network to rub or rub against the side surfaces of the building opening with its side edges during up and down movement, without the up and down movement of the network when released or when Closure of the building opening excessive force is necessary. In the closed position of the blind-like insect screen, the building opening is completely sealed without losing its air and light permeability. The effort for the insect protection according to the invention is approximately the same as that of an ordinary blind and is therefore considerably less than in the known constructions described at the beginning. Furthermore, the invention can be used for any building opening, as long as only the sections of the building opening side surfaces that interact with the side edges of the building are reasonably flat. The flexible net adapts itself to slight bumps. This also has the advantage that the insect protection according to the invention is independent of the adherence to precise dimensional tolerances, since within certain limits it does not matter if the side edges of the net are more or less bent on the sections of the seal when the net is moved up or down Lateral surfaces of the building opening, for example on the floor inner surfaces, rest as long as only the condition is maintained that the net side edge brushes against the section of the side surface of the building opening that cooperates with it and thus ensures the sealing effect. It is therefore sufficient to keep a certain standard width of the network to be used in stock for a certain width range of building openings to be closed, as a result of which expensive custom-made products can generally be avoided.

Die Fallstange begünstigt in an sich bekannter Weise durch ihr Gewicht die Abwärtsbewegung des Netzes, so daß auf den Netzunterrand bei seiner Abwärtsbewegung kein Zug ausgeübt werden muß. Die kürzer als die Netzbreite bemessene Fallstange behindert die seitlichen Netzränder in ihrer Dichtwirkung nicht und schleift auch nicht an den Seitenrändern der Stockflächen od.dgl., vielmehr wird sie durch die beiden Netzseitenränder annähernd mittig zwischen diesen beiden Stockflächen od.dgl. geführt.The drop bar favors the downward movement of the net due to its weight in a manner known per se, so that no train is exerted on the lower edge of the net during its downward movement must be practiced. The drop bar, which is shorter than the net width, does not hinder the side net edges in their sealing effect and does not grind on the side edges of the floor surfaces or the like. Rather, it is due to the two net side edges approximately in the middle between these two floor surfaces or the like. guided.

Ein weiterer Vorteil des erfindungsgemäßen Insektenschutzes liegt darin, daß die harmonikaartige Fixierung des Netzes zur Folge hat, daß es im zusammengelegten Zustand, also in der Freigabestellung der Gebäudeöffnung, nur sehr Wenig Platz einnimmt, so daß in dieser Stellung der Licht- bzw. Luftdurchgang durch die Gebäudeöffnung nicht oder nur unwesentlich beeinträchtigt wird. Die Fixierung des Netzes in Zickzackfalten sichert auch, das der zickzackartige Verlauf des Netzes auch dann erhalten bleibt, wenn das Netz im Gebrauch, z.B. durch Schlagregen, einmal naß wird.Another advantage of the insect protection according to the invention is that the harmonica-like fixation of the network means that it takes up very little space in the folded state, i.e. in the release position of the building opening, so that in this position the passage of light or air through the opening of the building is not or only slightly affected. The fixation of the net in zigzag folds also ensures that the zigzag-like course of the net is retained even when the net is in use, e.g. by driving rain, gets wet once.

Vor allem aber wird eine einwandfreie Abdichtung der Gebäudeöffnung gegen fliegende und kriechende Insekten erzielt, da keine Restspalte zwischen den Seitenrändern des Netzes und den ihnen benachbarten Abschnitten der Seitenflächen der Gebäudeöffnung mehr vorhanden sind.Above all, however, a perfect seal of the building opening against flying and crawling insects is achieved since there are no residual gaps between the side edges of the net and the adjacent sections of the side faces of the building opening.

Wie bereits erwähnt, kann die Auf- und Abbewegung des Netzes nach Art einer Jalousie erfolgen. Damit ist es möglich, die für Jalousien an sich bekannten Bewegungsmittel hiefür einzusetzen, etwa Zugschnüre, Gurte, Rollen mit Endlosschnüren, Kurbelantriebe, elektrische Antriebe usw. Vorzugsweise werden diese Antriebsmittel nur für die Hochziehbewegung des Netzes eingesetzt, wogegen das Absenken durch das Gewicht der Fallstange bewirkt wird. Eine besonders günstige Ausführungsform besteht im Rahmen der Erfindung dann, wenn der Mittelteil des Netzes zwischen den beiden abgebogenen Seitenrändern und zwischen je zwei benachbarten Faltkanten zumindest zwei in Abstand voneinander angeordnete Öffnungen hat, durch die Zugschnüre hindurchgeführt sind, die am Unterrand des Netzes an der Fallstange befestigt sind. Diese Öffnungen sind zweckmäßig von Langschlitzen, z.B. mit einer Länge von 5 mm, gebildet, deren Längsrichtung von oben nach unten gerichtet ist. Bei sinnvoller Bemessung der Größe dieser Langschlitze wird verhindert, daß Insekten durch diese Öffnungen hindurchtreten können, wobei zu berücksichtigen ist, daß der Öffnungsquerschnitt durch die hindurchtretende Zugschnur im wesentlichen ausgefüllt wird, so daß der verbleibende Öffnungsquerschnitt für ein Insekt zu klein ist. Da diese Öffnungen und somit die in ihnen geführten Zugschnüre zwischen den beiden abgebogenen Netzseitenrändern liegen, wird weder diese Abbiegung durch die Zugschnüre behindert, noch die Zugschnurfunktion durch die Abbiegung.As already mentioned, the up and down movement of the network can be done in the manner of a blind. This makes it possible to use the means of movement known per se for blinds, such as pull cords, belts, rollers with endless cords, crank drives, electric drives, etc. Preferably, these drive means are only used for the pull-up movement of the network, whereas the lowering by the weight of the drop bar is effected. A particularly favorable embodiment exists within the scope of the invention if the middle part of the net has at least two spaced-apart openings between the two bent side edges and between two adjacent folded edges, through which pull cords are guided, which are on the lower edge of the net on the drop bar are attached. These openings are expediently formed by long slots, for example with a length of 5 mm, the longitudinal direction of which is directed from top to bottom. If the size of these elongated slots is sensibly dimensioned, it is prevented that insects can pass through these openings, whereby it must be taken into account that the opening cross section is essentially filled by the pull cord which passes through, so that the remaining opening cross section is too small for an insect. Since these openings and thus the pull cords guided in them lie between the two bent network side edges, neither this turn is impeded by the pull cords nor the pull cord function by the turn.

Um zu vermeiden, daß das Netz durch Windeinfluß pendelt und damit die Dichtwirkung an den Netzseitenrändern beeinträchtigt wird, ist gemäß einer Weiterbildung der Erfindung der unterste Abschnitt des Netzes durch eine verstellbare Begrenzung, beispielsweise durch auf die Zugschnüre aufgeschobene und durch einen Knoten derselben gehaltene geschlitzte Lochscheiben, die mehrere der fixierten Faltkanten des Netzes zusammenhalten, auf die erforderliche aufziehbare Höhe der Gebäudeöffnung einstellbar. Dadurch wird auch der Vorteil erzielt, daß die Gesamtlänge des Netzes an die jeweils vorhandene Höhe der Gebäudeöffnung anpaßbar ist, so daß der nicht vollständig ausgezogene, zickzackförmig zusammengefaltete unterste Netzteil mittels der durch die Lochscheiben gebildeten Begrenzung an der Fallstange befestigt bleibt. Dadurch wird die Konstruktion auch an verhältnismäßig stark variierende Höhen der Gebäudeöffnung nach Bedarf anpaßbar. Die als Begrenzung verwendeten geschlitzten Lochscheiben können nach Art von geschlitzten Beilagscheiben ausgebildet sein.In order to avoid that the net oscillates due to the influence of wind and thus the sealing effect on the side edges of the net is impaired, according to a further development of the invention, the bottom section of the net is adjustable, for example by slotted perforated disks pushed onto the pull cords and held by a knot of the same , which hold several of the fixed folding edges of the net together, adjustable to the required height of the building opening. This also has the advantage that the total length of the network can be adapted to the existing height of the building opening, so that the not fully extended, zigzag folded bottom power supply remains attached to the drop bar by means of the boundary formed by the perforated disks. As a result, the construction can also be adapted to relatively widely varying heights of the building opening as required. The slotted perforated disks used as a limitation can be designed in the manner of slotted washers.

Wenn im Rahmen der Erfindung an der Unterseite der Fallstange Haftorgane, wie Schnapper, Druckknöpfe od.dgl. zur Befestigung am Unterrand der Gebäudeöffnung, z.B. am Fensterparapet, vorgesehen sind, wird eine Sicherung gegen Wind und Sturm geschaffen, so daß der untere Netzrand sowie die Fallstange nicht auspendeln kann.If in the context of the invention on the underside of the drop bar adhesive organs, such as snappers, push buttons or the like. For attachment to the lower edge of the building opening, for example on the window parapet, security against wind and storm is created, so that the lower edge of the network and the case rod cannot swing out.

Als Netzmaterial eignet sich insbesondere ein kunststoffbeschichtetes Glasfasergewebe. In ein solches können die fixierten Faltkanten zur Ausbildung der harmonikaartigen Form des Netzes ohne Schwierigkeiten eingebracht werden. Dadurch wird der Zickzackcharakter des Netzes für praktisch unbegrenzte Zeit aufrechterhalten, auch wenn das Netz an der Gebäudeaußenseite angeordnet und daher Regen und anderen Witterungseinflüssen ständig ausgesetzt ist.A plastic-coated glass fiber fabric is particularly suitable as the net material. In such a way, the fixed folded edges can be introduced without difficulty to form the harmonica-like shape of the net. As a result, the zigzag character of the network is maintained for a practically unlimited time, even if the network is arranged on the outside of the building and is therefore constantly exposed to rain and other weather influences.

Das erfindungsgemäße Verfahren zur Herstellung des erfindUngsgemäßen Insektenschutzes besteht darin, daß das insbesondere aus Glasfasern bestehende Netz mit einer die Netzmaschen fixierenden Substanz, z.B. flüssigem Kunststoff auf Vinylbasis, beschichtet und sodann unter Wärme- und Dampfeinwirkung in Zickzackfalten fixiert wird. Dadurch wird ein Netz geschaffen, das sich problemlos auf eine im wesentlichen gestreckte Stellung ausziehen läßt, jedoch nach Aufhören der die Streckung bewirkenden Kraft von selbst wieder in eine leicht zickzackförmig geformte Gestalt zurückkehrt und sich daher durch Aufziehen nach Art einer Jalousie zickzackartig zusammenlegt. Durch die Beschichtung der Netzmaschen wird verhindert, daß sich, insbesondere an den Faltkanten, die Netzmaschen vergrößern und Insekten hindurchschlüpfen können.The method according to the invention for producing the insect protection according to the invention consists in the fact that the net, which consists in particular of glass fibers, contains a substance that fixes the net mesh, e.g. liquid vinyl-based plastic, coated and then fixed under heat and steam in zigzag folds. This creates a network that can be easily extended to a substantially extended position, but after the force causing the stretching stops automatically returning to a slightly zigzag shape and therefore collapses like a blind in a zigzag manner. The coating of the mesh mesh prevents the mesh mesh from enlarging and insects from being able to slip through, particularly at the folded edges.

In der Zeichnung ist der Erfindungsgegenstand an Hand eines Ausführungsbeispieles schematisch dargestellt. Fig.1 zeigt die durch den erfindungsgemäßen Insektenschutz verschlossene Gebäudeöffnung in Frontansicht. Fig.2 ist ein Schnitt nach der Linie II - II in größerem Maßstab. Fig.3 ist ein Schnitt nach der Linie III - III der Fig.2. Die Fig.4 zeigt den Oberrand der Gebäudeöffnung am Beginn der Abwärtsbewegung des Netzes von seiner aufgezogenen Stellung in die Verschlußstellung. Fig.5 zeigt ebenfalls den Oberrand der Gebäudeöffnung, jedoch gegen Ende der Aufzugbewegung des Netzes. Fig.6 zeigt eine die Fixierung des unteren Netzrandes betreffende Variante in Seitenansicht.In the drawing, the subject of the invention is shown schematically using an exemplary embodiment. 1 shows a front view of the building opening closed by the insect screen according to the invention. Fig.2 is a section along the line II - II on a larger scale. Fig.3 is a section along the line III - III of Fig.2. 4 shows the upper edge of the building opening at the start of the downward movement of the network from its open position to the closed position. Fig. 5 also shows the upper edge of the building opening, but towards the end of the elevator movement of the network. 6 shows a side view of a variant relating to the fixation of the lower edge of the net.

Gemäß dem Ausführungsbeispiel der Zeichnung soll eine Gebäudeöffnung insektendicht und dennoch licht- und luftdurchlässig verschlossen werden. Die Gebäudeöffnung hat rechteckigen Querschnitt, der von der Stocklichte bzw. Mauerlichte begrenzt ist, die von zwei Seitenflächen 1, dem Fenstersturz 2 und dem Parapet 3 begrenzt wird. Am Fenstersturz 2 ist eine Kopfschiene 4 befestigt oder in den Fenstersturz eingelassen, die ein biegsames Netz 5 aus wetterfestem, verrottungsfestem Material, insbesondere aus einem Glasfasergewebe trägt. Dieses Netz 5 ist zickzackartig in Falten gelegt, deren Faltkanten 6 voneinander beim dargestellten Ausführungsbeispiel einen Abstand von etwa 40 mm aufweisen. Dieses Netz schließt in seiner gestreckten Stellung (Fig.1) die Gebäudeöffnung dicht ab. Hiezu ist die Breite B (Fig.1) des Netzes 5 geringfügig größer als die Breite b (lichte Breite) der Gebäudeöffnung, also der Abstand der beiden Seitenflächen 1 des Fensterrahmens bzw. der Mauerlichte voneinander. Dadurch schleift bzw. streift das Netz 5 an den Sei- tenflächen 1 und liegt an diesen Seitenflächen 1 dicht an, so daß sich eine absolute Dichtheit gegen einfliegende Insekten ergibt. An seinem Unterrand ist das Netz 5 mit einer Fallstange 7 verbunden, die am Parapet 3 befestigbar ist, z.B. mittels Schnappern,Druckknöpfen 8 od.dgl. Dadurch wird auch vermieden, daß sich das Netz 5, z.B. durch den Druck einfallenden Windes oder durch Zugluft, aus der Gebäudeöffnung herausbewegen kann, wodurch die erwähnte Dichtheit verloren ginge.According to the exemplary embodiment of the drawing, a building opening is to be closed so as to be insect-proof and yet permeable to light and air. The building opening has a rectangular cross section which is delimited by the stick lights or wall lights which are delimited by two side surfaces 1, the lintel 2 and the parapet 3. A head rail 4 is fastened to the lintel 2 or embedded in the lintel and carries a flexible network 5 made of weatherproof, rot-proof material, in particular of a glass fiber fabric. This net 5 is placed in zigzag folds, the fold edges 6 of which are at a distance of about 40 mm from each other in the illustrated embodiment. In its extended position (Fig. 1), this network closes the building opening tightly. For this purpose, the width B (FIG. 1) of the network 5 is slightly larger than the width b (clear width) of the building opening, that is to say the distance between the two side surfaces 1 of the window frame or the wall lights from one another. Characterized loops or clips the net 5 at the side faces 1 and is located on this side faces 1 to close, so that a perfect tightness against insects fly-results. At its lower edge, the net 5 is connected to a drop bar 7 which can be fastened to the parapet 3, for example by means of snaps, push buttons 8 or the like. This also prevents the network 5 from being able to move out of the building opening, for example due to the pressure of the wind or drafts, as a result of which the tightness mentioned would be lost.

Das Netz 5 kann in der Gebäudeöffnung bzw. innerhalb des Fensterrahmens zwischen einer zickzackförmig zusammengefalteten Stellung (Fig.4 bis 5), in der das Netz die Gebäudeöffnung zumindest teilweise freigibt, und einer gestreckten Stellung (Fig.1), in der das Netz 5 die Gebäudeöffnung abschließt, hin- und herbewegt werden, wozu zwei oder mehrere im Bereich der Seitenränder des Netzes 5 angeordnete Zugschnüre 9 vorgesehen sind, deren untere Enden an der Fallstange 7 befestigt sind und die oben durch die Kopfschiene 4 in an sich bekannter Weise zu einem gemeinsamen Zugorgan 10 (Fig.4,5) geführt sind, das in beliebiger an sich bekannter Weise in der aufgezogenen, zickzackartig zusammengefalteten Stellung des Netzes 5 arretierbar ist. Aus dieser Stellung kann das Netz 5 durch sein Eigengewicht und den Einfluß des Gewichtes der Fallstange 7 in Richtung des Pfeiles 12 (Fig.4) abgelassen werden, wobei die seitlichen Längsränder 11 des Netzes 5 sich infolge der Reibungshaftung an den Seitenflächen 1 nach oben umbiegen (Fig.4), was durch die elastische Biegsamkeit des Netzes 5 ermöglicht wird. Beim Hochziehen des Netzes 5 aus der gestreckten Stellung in die zickzackartig zusammengefaltete Freigabestellung in Rich tung des Pfeiles 13 der Fig.5 biegen sich die seitlichen Längsränder 11 des Netzes 5 nach unten um und schleifen an den Seitenflächen 1. Um zu vermeiden, daß bei den erwähnten Bewegungen die Fallstange 7 an den Seitenflächen 1 der Gebäudeöffnung schleift, ist die Fallstange 7 kürzer als die lichte Breite b der Gebäudeöffnung, wodurch auch ermöglicht wird, daß das Netz auf die erforderliche Breite der Gebäude- äffnung angepaßt werden kann.The net 5 can be in the building opening or within the window frame between a zigzag folded position (Fig. 4 to 5), in which the net at least partially clears the building opening, and an extended position (Fig. 1), in which the net 5 closes the building opening, back and forth, for which purpose two or more pull cords 9 are provided in the region of the side edges of the net 5, the lower ends of which are fastened to the drop bar 7 and the top by the head Rail 4 are in a known manner to a common tension member 10 (Fig.4,5), which can be locked in any known manner in the drawn, zigzag folded position of the network 5. From this position, the net 5 can be lowered due to its own weight and the influence of the weight of the drop bar 7 in the direction of arrow 12 (FIG. 4), the lateral longitudinal edges 11 of the net 5 bending upwards as a result of the frictional adhesion on the side surfaces 1 (Fig.4), which is made possible by the elastic flexibility of the net 5. When pulling the net 5 from the extended position into the zigzag folded release position in the direction of the arrow 13 of Figure 5, the lateral longitudinal edges 11 of the net 5 bend down and grind on the side surfaces 1. To avoid that at the movements mentioned, the drop bar 7 grinds on the side faces 1 of the building opening, the drop bar 7 is shorter than the clear width b of the building opening, which also enables the network to be adapted to the required width of the building opening.

Die Zugschnüre 9, vorzugsweise aus Terylene, durchsetzen Öffnungen 14 des Netzes 5, die von Langschlitzen mit einer Länge von etwa 5 mm gebildet sind, deren Längsseite (gesehen in der gestreckten Stellung des Netzes 5, Fig.1) von oben nach unten gerichtet ist. Diese Öffnungen 14 sind jeweils in der der Anzahl der Zugschnüre 9 entsprechenden Anzahl zwischen je zwei benachbarten Faltkanten 6 des Netzes 5 vorgesehen und so bemessen, daß die Zugschnüre 9 möglichst eng hindurchtreten, so daß durch den verbleibenden Spalt Insekten nicht hindurchtreten können.The pull cords 9, preferably made of terylene, pass through openings 14 of the net 5, which are formed by elongated slots with a length of about 5 mm, the long side of which (seen in the extended position of the net 5, FIG. 1) is directed from top to bottom . These openings 14 are each provided in the number corresponding to the number of pull cords 9 between each two adjacent folding edges 6 of the net 5 and dimensioned such that the pull cords 9 pass through as closely as possible so that insects cannot pass through the remaining gap.

Das.zickzackförmig gefaltete Netz 5 nach Art einer Jalousie soll auch so ausgebildet sein, daß es für einen möglichst weiten Höhenbereich der Gebäudeöffnung universell einsetzbar ist. Hiezu wird die vom unteren Teil 15 (Fig.6) gebildete Überlänge des Netzes 5 in der gestreckten Stellung des Netzes 5 dadurch an der Entfaltung behindert, daß dieser Netzteil 15 durch Begrenzungen an der Fallstange 7 festgehalten wird. Diese Begrenzungen sind von geschlitzten Lochscheiben 16 gebildet, die auf die Zugschnüre 9 aufgeschoben und durch Knoten 17 der Zugschnüre 9 gehalten sind.Das.zigzag folded network 5 in the manner of a blind should also be designed so that it can be used universally for the widest possible height range of the building opening. For this purpose, the excess length of the net 5 formed by the lower part 15 (FIG. 6) in the extended position of the net 5 is prevented from developing by the fact that the latter Power supply 15 is held by limits on the drop bar 7. These limits are formed by slotted perforated disks 16 which are pushed onto the pull cords 9 and held by knots 17 of the pull cords 9.

Das Netz 5 besteht aus einem Glasfasergewebe, das fixierte Faltkanten hat. Hiezu wird das Glasfasernetz mit einer die Netzmaschen fixierenden Substanz, insbesondere flüssigem Vinylkunststoff, beschichtet und sodann unter Wärme- und Dampfeinwirkung plisseeartig fixiert.The net 5 consists of a glass fiber fabric that has fixed folded edges. For this purpose, the glass fiber network is coated with a substance that fixes the mesh, in particular liquid vinyl plastic, and then fixed like a pleat under the influence of heat and steam.
