Description

Die Erfindung betrifft eine Plisseevorrichtung zur Abschirmung einer Gebäudeöffnung gegen Insekten gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a pleated blind device for shielding a building opening from insects according to the preamble of patent claim 1.

Derartige Insektenschutzplissees für Türen sind üblicherweise oben und unten lose in einem Rahmenprofil geführt. Durch Winddruck kann das Plisseegewebe aus dieser Führung heraustreten und ungewollt beschädigt werden. Ein weiteres Problem ist die Belastung der durch das Gewebe hindurch verlaufenden Stabilisierungsfäden. Aufgrund der geforderten Dichtheit gegen Insekten können die Durchführungslöcher eine gewisse Größe nicht überschreiten, so dass Reibungsschäden auftreten können. Weitere Randbedingungen bestehen in der Einhaltung einer möglichst geringen Bautiefe und einer möglichst ungehinderten Handhabung.Such pleated insect screens for doors are usually guided loosely in a frame profile at the top and bottom. Wind pressure can cause the pleated blind fabric to come out of this guide and be damaged unintentionally. Another problem is the stress on the stabilizing threads running through the fabric. Due to the required tightness against insects, the lead-through holes cannot exceed a certain size, so that friction damage can occur. Further boundary conditions consist in maintaining the smallest possible construction depth and as unhindered handling as possible.

In der EP 2 986 802 B1 wird das Problem des Winddrucks bei größer dimensionierten Anlagen beschrieben und zur Abhilfe vorgeschlagen, durch einen beweglichen Zwischenschieberahmen für eine Aufteilung der großen Fläche zu sorgen. Nachteilig hierbei sind der erhöhte Fertigungs- und Handhabungsaufwand und die reduzierte Durchsicht im Bereich der Gebäudeöffnung.In the EP 2 986 802 B1 the problem of wind pressure in larger-scale systems is described and a remedy proposed is to use a movable intermediate sliding frame to divide up the large area. The disadvantage here is the increased production and handling costs and the reduced view in the area of the building opening.

Die EP 1 739 271 A2 offenbart eine Fensterabdeckung mit einem Wabenplissee, das allerdings keine durchlüftbare Gitterstruktur nach Art eines Insektenschutzgewebes besitzt. Dort ist der obere Rand des Plissess mit einer oberen Schiene über eine Vielzahl von hakenartigen Hängeelementen verschieblich verbunden.the EP 1 739 271 A2 discloses a window covering with a honeycomb pleated blind, which, however, does not have a lattice structure that can be ventilated in the manner of an insect protection fabric. There, the upper edge of the pleated blind is slidably connected to an upper rail via a large number of hook-like hanging elements.

Die US2013/0118694 A1 offenbart ebenfalls Hängeelemente, die an dem oberen Rand eines Insektenschutzplissees feststehend angebracht sind.the US2013/0118694 A1 also discloses hanging elements fixedly attached to the top edge of a pleated insect screen.

Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, die im Stand der Technik bekannten Plisseevorrichtungen weiter zu verbessern und eine mit geringem Herstellungsaufwand bereitstellbare, robuste und dennoch einfach handhabbare Konstruktion anzugeben.Proceeding from this, the invention is based on the object of further improving the pleated blind devices known in the prior art and of specifying a construction that can be provided with little manufacturing effort, is robust and yet easy to handle.

Zur Lösung dieser Aufgabe wird die im Patentanspruch 1 angegebene Merkmalskombination vorgeschlagen. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.To solve this problem, the combination of features specified in claim 1 is proposed. Advantageous refinements and developments of the invention result from the dependent claims.

Die Erfindung geht von dem Gedanken aus, das Plisseegewebe gegen Winddruck und andere Sonderbelastungen durch eine einfache Maßnahme zu stabilisieren. Um der Bewegung der Falten des Plisseegewebes beim Ein- und Entfalten folgen zu können, wird erfindungsgemäß vorgeschlagen, dass das Verbindungsstück an dem Laufkörper um eine Vertikalachse drehbeweglich gelagert ist. Dadurch kann eine auch optisch ansprechende schlanke Gestaltung auch bei größeren Flächenabdeckungen beibehalten werden, ohne dass auffällige und aufwändige konstruktive Eingriffe erforderlich wären. In der ohnehin vorhandenen oberen Führungsschiene lassen sich das oder die Sicherungselemente unauffällig unterbringen. Zugleich können damit zusätzliche Belastungen aufgenommen und über die Führungsschiene abgetragen werden.The invention is based on the idea of using a simple measure to stabilize the pleated fabric against wind pressure and other special loads. In order to be able to follow the movement of the folds of the pleated fabric when folding and unfolding, it is proposed according to the invention that the connecting piece on the running body is rotatably mounted about a vertical axis. As a result, a slim design that is also visually appealing can be maintained even with larger area coverages, without the need for conspicuous and complex structural interventions. The safety element or elements can be accommodated inconspicuously in the upper guide rail that is already present. At the same time, additional loads can be absorbed and transferred via the guide rail.

Das Sicherungselement ist in der Führungsschiene geführt und mit dem oberen Rand des Plisseegewebes punktuell verbunden, so dass eine Mitbewegung der Verbindungsstelle im Zuge der Plissebetätigung selbsttätig erfolgen kann.The safety element is guided in the guide rail and is connected to the upper edge of the pleated fabric at certain points, so that the connection point can move automatically when the pleated fabric is actuated.

Das Sicherungselement weist einen entlang der Führungsschiene beweglichen Laufkörper auf. Ein solcher Laufkörper kann als Gleit- oder Wälzkörper ausgeführt sein.The securing element has a running body that can be moved along the guide rail. Such a running body can be designed as a sliding or rolling body.

Eine vorteilhafte Ausgestaltung sieht vor, dass der Laufkörper eine an einer inneren Profilstruktur der Führungsschiene vorzugsweise gleitend geführte Hinterschneidung aufweist. Dadurch kann mit geringem konstruktiven Aufwand eine zuverlässige Rückhaltung bei gleichzeitiger Längsbeweglichkeit in der Führung gewährleistet werden.An advantageous embodiment provides that the running body has an undercut that is preferably guided in a sliding manner on an inner profile structure of the guide rail. As a result, reliable restraint with simultaneous longitudinal mobility in the guide can be guaranteed with little design effort.

Um eine möglichst ungehinderte Bewegung sicherzustellen, ist es auch von Vorteil, wenn der Laufkörper eine an mindestens einer Seitenwand der Führungsschiene verkantungsfrei anliegende Leitkontur aufweist.In order to ensure a movement that is as unimpeded as possible, it is also advantageous if the running body has a guiding contour which rests against at least one side wall of the guide rail without tilting.

Auch montagetechnisch ergeben sich weitere Vereinfachungen dadurch, dass der Laufkörper eine vertikal in die Führungsschiene einrast- oder einklickbare, gegebenenfalls unter Kompression lösbare Kopfpartie umfasst. Eine weitere Herstellungsvereinfachung lässt sich dadurch erreichen, dass der Laufkörper als Spritzgussteil aus Kunststoff gebildet ist. Um auch die Gleiteigenschaften zu verbessern, sollte vorzugsweise ein Teflon-haltiger Kunststoff eingesetzt werden.Further simplifications also result in terms of assembly technology in that the running body comprises a head section which can be latched or clicked vertically into the guide rail and, if necessary, can be released under compression. A further simplification of production can be achieved in that the running body is formed as an injection molded part made of plastic. In order to also improve the sliding properties, a Teflon-containing plastic should preferably be used.

Zur Schaffung einer lokal wirksamen Verbindung weist das Sicherungselement ein am oberen Rand des Plisseegewebes angebrachtes Verbindungsstück auf. In diesem Zusammenhang ist es auch vorteilhaft, wenn das Verbindungsstück zur Übertragung einer durch das Plisseegewebe eingebrachten Zugbelastung zugfest mit dem Laufkörper verbunden ist.In order to create a locally effective connection, the securing element has a connecting piece attached to the upper edge of the pleated fabric. In this context, it is also advantageous if the connecting piece is connected to the running body in a tension-proof manner in order to transmit a tensile load introduced by the pleated fabric.

Vorteilhafterweise ist das Verbindungsstück an dem Laufkörper um mindestens 90° drehbeweglich gelagert.Advantageously, the connecting piece is mounted on the running body such that it can rotate through at least 90°.

Für die Übertragung axialer Kräfte beim Einsetzen in die Führungsschiene ist es günstig, wenn das Verbindungsstück über einen Stößel an dem Laufkörper nach oben abgestützt ist.For the transmission of axial forces when inserting into the guide rail, it is favorable if the connecting piece is supported upwards via a ram on the running body.

Vorteilhafterweise ist das Verbindungsstück über eine Klebestelle vorzugsweise in Form eines über den oberen Rand hinweg beidseitig an dem Plisseegewebe fixierten Klebestreifens an dem Plisseegewebe fixiert.Advantageously, the connecting piece is fixed to the pleated fabric via an adhesive point, preferably in the form of an adhesive strip fixed to both sides of the pleated fabric over the upper edge.

Um eine möglichst werkzeuglose Montage zu unterstützen, ist es vorteilhaft, wenn das Verbindungsstück über eine Stützscheibe auf dem oberen Rand des Plisseegewebes aufliegt. Dadurch lässt sich das Sicherungselement durch Druckausübung über das Gewebefaltpaket in die Führungsschiene einrasten.In order to support an assembly that is as tool-free as possible, it is advantageous if the connecting piece rests on the upper edge of the pleated fabric via a supporting disc. As a result, the securing element can be snapped into the guide rail by exerting pressure on the folded fabric package.

Um eine Zerstörung bei übermäßigen Belastungen zu vermeiden, sollte das Sicherungselement bei Überschreiten einer vorbestimmten Zugbelastung aus der Führungsschiene selbsttätig auslösen.In order to avoid destruction in the event of excessive loads, the safety element should trigger automatically when a predetermined tensile load from the guide rail is exceeded.

Für die Sicherung größerer Anlagen ist es von Vorteil, wenn mehrere Sicherungsstücke in einem gegenseitigen Abstand entlang dem oberen Rand des Plisseegewebes verteilt angeordnet sind, wobei der Abstand im Bereich von 0,2 bis 1,2m, vorzugsweise 0,5 bis 0,8m gewählt werden sollte.For securing larger systems, it is an advantage if several security pieces are in a mutual Distance along the upper edge of the pleated fabric are arranged distributed, the distance should be chosen in the range of 0.2 to 1.2 m, preferably 0.5 to 0.8 m.

Im Folgenden wird die Erfindung anhand des in der Zeichnung in schematischer Weise dargestellten Ausführungsbeispiels näher erläutert. Es zeigen

Die in Fig. 1 gezeigte Insektenschutz-Plisseevorrichtung 10 umfasst ein faltbares, horizontal ausziehbares Plisseegewebe 12, ein Fadensystem 14 mit mehreren parallel zueinander durch das Plisseegewebe 12 verlaufenden Stabilisierungsfäden 16, eine Schiebeleiste 18 zum Ent- und Einfalten des Plisseegewebes 12, einen an oder in einer Gebäudeöffnung anbringbaren Führungsrahmen 20 für das Plisseegewebe 12 bzw. die Schiebeleiste 18 und mindestens ein in einer oberen Führungsschiene 22 des Führungsrahmens 20 angeordnetes Sicherungselement 24 zur Sicherung des Plisseegewebes 12 bei ungewöhnlichen Belastungen beispielsweise unter Windeinfluss. Das Sicherungselement 24 ist hierfür in der Führungsschiene 22 beweglich geführt und mit dem oberen Rand 26 des Plisseegewebes 12 punktuell verbunden.In the 1 The insect protection pleated blind device 10 shown comprises a foldable, horizontally extendable pleated blind fabric 12, a thread system 14 with a plurality of stabilizing threads 16 running parallel to one another through the pleated blind fabric 12, a sliding bar 18 for unfolding and folding in the pleated blind fabric 12, a guide frame 20 which can be attached to or in a building opening for the pleated fabric 12 or the sliding bar 18 and at least one arranged in an upper guide rail 22 of the guide frame 20 securing element 24 for securing the pleated fabric 12 in unusual loads, for example under the influence of wind. For this purpose, the securing element 24 is movably guided in the guide rail 22 and connected to the upper edge 26 of the pleated fabric 12 at certain points.

Das Plisseegewebe 12 besitzt als gewebtes Flächengebilde gegensinnig eingebrachte Falten, die in der Offenstellung der Plisseevorrichtung 10 kompakt gegeneinander anliegen und in der in Fig. 1 gezeigten Schließstellung entfaltet sind.As a woven fabric, the pleated fabric 12 has folds inserted in opposite directions, which lie compactly against one another in the open position of the pleated blind device 10 and in the in 1 shown closed position are deployed.

Der Führungsrahmen 20 besitzt zwei einander gegenüberliegende, in der Einbaulage vertikale Aufnahmeschenkel 28, die mit der oberen horizontalen Führungsschiene 22 und einer unteren Laufschiene 30 verschraubt werden können. Damit wird der vierseitig geschlossene Führungsrahmen 20 geschaffen, der sowohl stirnseitig in einer Laibung als auch von außen an einer nicht gezeigten Gebäudeöffnung montiert werden kann. Die untere U-förmige Laufschiene 30 besitzt eine geringe Höhe und erlaubt damit auch ein einfaches Begehen, während die obere U-förmige Führungsschiene 22 mit einer größeren Profilhöhe für einen randseitigen Halt des Plisseegewebes 12 bei gewöhnlichem Gebrauch sorgt.The guide frame 20 has two opposite, vertical in the installed position receiving leg 28, which can be screwed to the upper horizontal guide rail 22 and a lower rail 30. This creates the four-sided closed guide frame 20, which is both on the front side in a reveal as well as from the outside can be mounted on a building opening, not shown. The lower U-shaped guide rail 30 has a low height and thus also allows easy access, while the upper U-shaped guide rail 22 with a greater profile height ensures that the pleated fabric 12 is held at the edge during normal use.

Das Plisseegewebe 12 wird über das Fadensystem 14 in seiner Gebrauchslage abgestützt. Zu diesem Zweck sind die Stabilisierungsfäden 16 in der Mittelebene des Führungsrahmens 20 durch vergrößerte Gewebeöffnungen hindurchgeführt, wobei über den Innenraum der Schiebeleiste 18 eine Fadenumlenkung vorgesehen ist. Die endseitige Fadenfixierung erfolgt dabei zweckmäßig unter Federvorspannung im Bereich des öffnungsseitigen Aufnahmeschenkels 28.The pleated fabric 12 is supported by the thread system 14 in its position of use. For this purpose, the stabilizing threads 16 are passed through enlarged fabric openings in the central plane of the guide frame 20, a thread deflection being provided via the interior of the sliding strip 18. The thread fixing at the end is expediently carried out under spring pretension in the area of the receiving leg 28 on the opening side.

Wie in Fig. 2 gezeigt, ist die obere Führungsschiene 22 durch ein nach unten offenes U-Profil gebildet, welches mit seinen Seitenschenkeln 32 den oberen Rand 26 des Plisseegewebes 12 seitlich umgreift. An der Innenwand der Seitenschenkel 32 sind gegeneinander weisende Führungsrippen 34 angeformt, die eine Gleitfläche für das bzw. die Sicherungselement(e) 24 bilden.As in 2 shown, the upper guide rail 22 is formed by a downwardly open U-profile, which with its side legs 32 engages the upper edge 26 of the pleated fabric 12 laterally. Guide ribs 34 pointing towards one another are formed on the inner wall of the side limbs 32 and form a sliding surface for the securing element(s) 24 .

Wie auch aus Fig. 3 ersichtlich, umfasst jedes Sicherungselement 24 einen innenseitig entlang der Führungsschiebe 22 beweglichen Laufkörper 36 und ein am oberen Rand 26 des Plisseegewebes 12 angebrachtes Verbindungsstück 38.As well as from 3 As can be seen, each securing element 24 comprises a running body 36 that can be moved on the inside along the guide slide 22 and a connecting piece 38 attached to the upper edge 26 of the pleated fabric 12.

Der Laufkörper 36 weist eine vertikal in die Führungsschiene 22 zwischen den Führungsrippen 34 einrastbare Kopfpartie 40. Diese besitzt einander gegenüberliegende Hinterschneidungen 42, die auf den Führungsrippen 34 gleiten. Um dabei ein Verkanten zu vermeiden, ist die Kopfpartie 40 mit seitlich auskragenden Leitkonturen 44 versehen, die innenseitig an den Seitenschenkeln 32 der Führungsschiebne 22 anliegen. Die Gleiteigenschaften werden dadurch weiter verbessert, dass der Laufkörper 36 als Spritzgussteil aus einem Teflon-haltigen Kunststoff gebildet ist. Falls erforderlich, lässt sich der Laufkörper 36 aus der Führungsschiebe 22 lösen, indem nach unten gabelartig abstehende Fortsätze 46 beispielsweise mit Hilfe einer Zange gegeneinander zusammengedrückt werden.The running body 36 has a head section 40 which can be latched vertically into the guide rail 22 between the guide ribs 34 . In order to avoid tilting, the head section 40 is provided with laterally projecting guide contours 44 which abut the side limbs 32 of the guide slide 22 on the inside. The sliding properties are further improved in that the running body 36 is formed as an injection molded part from a plastic containing Teflon. If necessary, the running body 36 can be detached from the guide slide 22 by fork-like protruding extensions 46 being pressed together against one another, for example with the aid of pliers.

Das Verbindungsstück 38 ist zugfest, jedoch um eine Vertikalachse drehbeweglich mit dem Laufkörper 36 verbunden. Dadurch kann eine Zuglast aufgenommen werden, während die Drehbeweglichkeit der Gewebebewegung beim Ein- und Entfalten folgt. Dies wird zweckmäßig durch einen Stößel 48 erreicht, der in einem Drehgelenk 50 gelagert ist (Fig. 3). Der Stößel 48 ist an seinem freien Ende 52 an dem Kopfstück 40 nach oben abgestützt, so dass die erforderliche Kraft zum Einrasten in die Führungsrippen 34 übertragen werden kann. Diese Kraft kann bei der Montage dadurch aufgebracht werden, dass das das Verbindungsstück 38 über eine Stützscheibe 54 auf dem oberen Rand 26 des zusammengefalteten Plisseegewebes 12 flächig abgestützt ist.The connecting piece 38 is tension-resistant but connected to the running body 36 such that it can rotate about a vertical axis. This allows a tensile load to be absorbed while the rotational mobility follows the tissue movement during folding and unfolding. This is expediently achieved by a ram 48 which is mounted in a rotary joint 50 is stored ( 3 ). At its free end 52, the plunger 48 is supported upwards on the head piece 40, so that the force required for latching into the guide ribs 34 can be transmitted. This force can be applied during assembly in that the connecting piece 38 is supported over a surface area via a support disk 54 on the upper edge 26 of the folded pleated fabric 12 .

In Fig. 4 und 5 ist die punktuelle Verbindung des Sicherungselements 24 am oberen Rand 26 des Plisseegewebes 12 näher veranschaulicht. In einem ersten Montageschritt wird hierfür ein quer gefalteter Klebestreifen 56 beidseitig an einer Gewebefalte klebend fixiert. Ein über den oberen Geweberand 26 überstehender Endabschnitt des Klebestreifens 56 ist mit einem Querdurchbruch 58 versehen, durch welchen ein Befestigungsmittel 60 des Verbindungsstücks 38 hindurchgreift. Die Klebeverbindung ist dabei derart belastbar, dass bei Überschreiten einer Grenzkraft das Kopfstück 40 aus den Führungsrippen 34 auslöst, so dass eine ungewollte Zerstörung verhindert wird. Je nach vorgesehener Lastaufnahme und Dimensionierung des Plisseegewebes 12 können mehrere Sicherungsstücke 24 beabstandet voneinander an dem oberen Geweberand 26 verteilt angebracht werden.In Figures 4 and 5 the selective connection of the securing element 24 at the upper edge 26 of the pleated fabric 12 is illustrated in more detail. In a first assembly step, a transversely folded adhesive strip 56 is adhesively fixed to a fabric fold on both sides. An end section of the adhesive strip 56 protruding beyond the upper fabric edge 26 is provided with a transverse opening 58 through which a fastening means 60 of the connecting piece 38 extends. The adhesive connection can be loaded in such a way that when a limit force is exceeded, the head piece 40 is released from the guide ribs 34, so that unwanted destruction is prevented. Depending on the intended load capacity and dimensioning of the pleated fabric 12, a plurality of securing pieces 24 can be attached to the upper fabric edge 26 at a distance from one another.
