Description

Die Erfindung betrifft ein Insektenschutzgitter, insbesondere für Tür-, Fenster- und ähnliche Wandöffnungen mit einem zwischen einer Offen- und einer Schliessstellung verschiebbaren Gitterrahmen, sowie ein Verfahren zu dessen Herstellung.The invention relates to an insect screen, in particular for door, window and similar wall openings with a movable between an open and a closed position grid frame, and a method for its production.

Insektenschutzgitter dieser Art verhindern, dass Insekten in Räume mit offenen Wandöffnungen eindringen können, solange das Schutzgitter geschlossen ist. Wird das Schutzgitter geöffnet, bewirkt das jedes Mal eine Unterbrechung der Schutzwirkung. Ein Schutzgitter dieser Art ist in der CH 702 037 B1 geoffenbart.Insect screens of this type prevent insects from entering rooms with open wall openings, as long as the protective grid is closed. When the guard is opened, this always causes an interruption of the protective effect. A protective grid of this kind is in the CH 702 037 B1 revealed.

Insektenschutzgitter sind an sich bekannt. Die Betätigung des Schutzgitters erfolgt aber dort durch einen Elektromotor im Zusammenwirken mit elektrischen Endschaltern. Derartige Schutzgitter haben damit den Nachteil eines aufwendigen und störungsanfälligen Aufbaus. Es kommt hinzu, dass bei ihnen zwingend ein elektrischer Anschluss benötigt wird.Insect screens are known per se. The operation of the protective grid is done but there by an electric motor in cooperation with electrical limit switches. Such protective grid thus have the disadvantage of a complex and fault-prone construction. In addition, they require an electrical connection.

In der Druckschrift WO-A-03/027425 ist eine Schließeinrichtung für eine Schiebetüre geoffenbart, wobei letztere einen Rahmen und ein in diesem gehaltenes Gitter aufweist. Diese Schiebetüre ist in einem Türrahmen verschiebbar gehalten. Es sind bei ihren oberen Ecken Verbindungselemente vorgesehen, welche die Längsprofile zusammenhalten. In diesen Verbindungselementen sind Durchgangsöffnungen vorhanden, welche zur Führung eines Kabels dienen, das am einen Ende mit einem in dem vertikalen Längsprofil geführten Gewicht und über ein Pulley durch das obere Längsprofil hindurch horizontal nach aussen geführt und mit seinem andern Ende an dem Türrahmen befestigt ist. Nachteilig hierbei ist zum einen, dass der Türrahmen aus diesen Verbindungselementen und den Längsprofilen in aufwändiger Weise zusammengesetzt und dass zum andern dieses Kabel bis zum seitlichen Türrahmen geführt ist, womit es in der geöffneten Stellung der Schiebetüre sichtbar ist und störend sein kann.In the publication WO-A-03/027425 a sliding door closure device is disclosed, the latter having a frame and a grid held therein. This sliding door is slidably held in a door frame. There are provided at their upper corners connecting elements which hold the longitudinal profiles together. Through-openings are provided in these connecting elements which serve to guide a cable which is guided horizontally outwards at one end with a weight guided in the vertical longitudinal profile and over a pulley through the upper longitudinal profile and is fastened at its other end to the door frame. The disadvantage here is the one that the door frame composed of these fasteners and the longitudinal profiles in a complex manner and that on the other hand this cable is guided to the side door frame, so it is visible in the open position of the sliding door and can be annoying.

Der Erfindung liegt die Aufgabe zugrunde, ein Insektenschutzgitter für Tür-, Fenster- und ähnliche Wandöffnungen zu schaffen, das nach Öffnung des Gitters schnell mit konstruktiv einfachen Mitteln wieder schliesst.The invention has for its object to provide an insect screen for door, window and similar wall openings, which quickly closes after opening the grid with structurally simple means again.

Diese Aufgabe wird erfindungsgemäss durch ein Insektenschutzgitter nach dem Anspruch 1 und ein Verfahren zur Herstellung eines Insektenschutzgitters nach dem Anspruch 8 gelöst, wobei im Gitterrahmen eine mechanische Betätigungseinrichtung zum selbsttätigen Rückführen des Gitters in die Schliessstellung eingebaut ist.This object is achieved according to the invention by an insect screen according to claim 1 and a method for producing an insect screen according to claim 8, wherein in the grid frame, a mechanical actuator for automatically returning the grid is installed in the closed position.

Zwecks einer verzögerungsfreien Rückführung des Schutzgitters sieht die Erfindung vor, dass in der Offenstellung des Gitters die Betätigungseinrichtung beim Loslassen des Gitterrahmens aktiv wird.For the purpose of a delay-free return of the protective grid, the invention provides that in the open position of the grid, the actuating device when releasing the grid frame is active.

Die Betätigungseinrichtung weist erfindungsgemäss einen um eine Umlenkrolle geführten Seilzug auf, dessen eines Ende an einer oberen Laufschiene für den Gitterrahmen befestigt ist und an dessen anderem Ende ein im Gitterrahmen frei bewegliches Gegengewicht aufgehängt ist. Eine solche Konstruktion besteht aus wenigen robusten Bauteilen, die keine aufwendige Wartung erfordern und keinen nennenswerten Reibungskräften ausgesetzt sind.The actuator according to the invention comprises a guided around a pulley cable, one end of which is attached to an upper rail for the lattice frame and at the other end a freely movable counterweight in the lattice frame is suspended. Such a construction consists of a few robust components that require no complex maintenance and are not exposed to significant frictional forces.

Um den Einbau der Betätigungseinrichtung in den Gitterrahmen zu erleichtern, sieht die Erfindung vor, dass der Seilzug durch einen im Gitterrahmen befestigbaren Gleitschieber geführt ist, der mit einer Lagerung für die Umlenkrolle versehen ist.In order to facilitate the installation of the actuator in the grid frame, the invention provides that the cable through one in the grid frame fastened sliding slider is guided, which is provided with a bearing for the deflection roller.

Dadurch ist es gemäss dem Herstellverfahren nach der Erfindung möglich, vor dem Zusammenbau des Gitterrahmens den Gleitschieber samt Umlenkrolle, Seilzug und Gegengewicht in das Profil des Gitterrahmens einzuschieben und den Gleitschieber an der vorgesehenen Stelle zu platzieren. Der Seilzug ist vorzugsweise aus einer Nylonschnur hergestellt.Thereby, it is possible according to the manufacturing method according to the invention to insert before the assembly of the lattice frame the slide together with pulley, cable and counterweight in the profile of the lattice frame and to place the slide at the intended location. The cable is preferably made of a nylon cord.

Es ist für eine kräftemässig günstige Führung des Seilzuges vorteilhaft, wenn der Gleitschieber im oberen Eckbereich des Gitterrahmens vorzugsweise beim Gehrungsschnitt eingebaut ist, und das Gegengewicht entlang des dort anstossenden Seitenprofils des Gitterrahmens beweglich ist. Es ist hierbei zur Minimierung der Reibung zweckmässig, wenn des Gegengewicht beflockt ist und dem Profilquerschnitt des Seitenprofils angepasst ist.It is advantageous for a power moderately favorable guidance of the cable, when the slide is installed in the upper corner of the lattice frame preferably at the miter cut, and the counterweight along the adjoining side profile of the grid frame is movable. It is expedient here to minimize the friction when the counterweight is flocked and adapted to the profile cross section of the side profile.

Die Erfindung sieht ausserdem vor, dass der Gleitschieber mit einem U-förmigen Profil zur Aufnahme eines Führungsstegs der oberen Laufschiene versehen ist. Auf diese Weise ist es möglich, das Gitter in der oberen Laufschiene sicher zu führen ohne diese zu belasten, wenn der Gitterrahmen, wie nach dem Stand der Technik vielfach üblich, mit Laufrollen auf einer unteren Laufschiene abgestützt ist.The invention also provides that the slide is provided with a U-shaped profile for receiving a guide web of the upper track rail. In this way it is possible to safely guide the grid in the upper track without burdening them, when the grid frame, as is common practice in the prior art, is supported with rollers on a lower track rail.

Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels unter Bezugnahme auf die Zeichnung näher erläutert. Es zeigen:

The invention will be explained in more detail with reference to an embodiment with reference to the drawing. Show it:
Fig. 1
a schematic diagram of an inventive insect screen with an actuator,
Fig. 2
a front detail view with an actuator of an insect screen, and

the actuator according to Fig. 2 in longitudinal section.

Das in Fig. 1 gezeigte Insektenschutzgitter mit einer Schiebetür 2 ist mit einem Gitter 6 versehen, das in einem vorzugsweise aus Längsprofilen 8, 9 zusammengesetzten Gitterrahmen 7 befestigt ist. Bei Verwendung des Schutzgitters in Wohnräumen ist das Gitter 6 vorzugsweise aus Kunststoffmaterial hergestellt. In anderen Fällen, wie etwa bei gewerblichen Nutzräumen, kann sich eher ein metallisches Gitter besser eignen.This in Fig. 1 shown insect screen with a sliding door 2 is provided with a grid 6 which is fixed in a preferably composed of longitudinal profiles 8, 9 grid frame 7. When using the protective grid in living spaces, the grille 6 is preferably made of plastic material. In other cases, such as in commercial premises, a metallic grid may be more suitable.

Diese Schiebetür 2 ist in einem nicht näher veranschaulichten Tür- oder Fensterrahmen montiert. Das Gitter 1 kann auch direkt in einer tür- oder fensterlosen Wandöffnung montiert sein. Es hat die Aufgabe, zu verhindern, dass durch die Wandöffnung Insekten in den Innenraum eindringen können.This sliding door 2 is mounted in a non-illustrated door or window frame. The grid 1 can also be mounted directly in a door or windowless wall opening. Its task is to prevent insects from entering the interior through the wall opening.

Erfindungsgemäss ist in der Schiebetüre 2 eine mechanische Betätigungseinrichtung 5 zum Selbstschliessen der Schiebetüren eingebaut.According to the invention, a mechanical actuating device 5 for self-closing of the sliding doors is installed in the sliding door 2.

Zweckmässigerweise sind dem Gitterrahmen 7 Laufrollen 10 zugeordnet, mittels denen er zwischen einer Offen- und einer Schliessstellung entlang einer unteren Laufschiene 11 und einer oberen Laufschiene 12 verfahrbar ist. Die Laufschienen 11 und 12 sind so ausgestaltet, dass die Schiebetüre jederzeit aus den Laufschienen herausgenommen werden kann.Conveniently, the grid frame 7 rollers 10 are assigned, by means of which it is movable between an open and a closed position along a lower rail 11 and an upper rail 12. The rails 11 and 12 are designed so that the sliding door can be removed at any time from the rails.

Gemäss Fig. 2 und Fig. 3 weist die Betätigungseinrichtung 5 zum Selbstschliessen der Tür einen um eine Umlenkrolle 13 geführten Seilzug 14 auf, dessen eines Ende 15 an der oberen Laufschiene 12 befestigt ist und an dessen anderem Ende 16 ein in einer Profilnut 8' im Längsprofil 8 des Gitterrahmens 7 bewegliches Gegengewicht 17 hängt. Die Umlenkrolle 13 ist in einem Gleitschieber 18 gelagert, der vor dem Zusammenbau des Gitterrahmens 7 leicht in dessen hinteren Eckbereich einbaubar ist. Der Seilzug 14 ist im Gleitschieber 18 so geführt, dass er durch das Gegengewicht 17 auf einer annähernd senkrechten Bahn gezogen wird. Das vorzugsweise beflockte Gegengewicht 17 ist dem Querschnitt der Profilnut 8' im Längsprofil 8 angepasst und somit darin reibungs- und geräuscharm sicher geführt. Am oberen Türende in der Profilnut 8' wird der Seilzug 14 durch die Umlenkrolle 13 so umgelenkt, dass er bei geöffnetem Gitter annähernd waagerecht ausgestreckt ist.According to Fig. 2 and Fig. 3 the actuator 5 for self-closing the door on a guide roller 13 guided cable 14, one end 15 is fixed to the upper rail 12 and at the other end 16 in a profile 8 'in the longitudinal profile 8 of the lattice frame 7 movable counterweight 17th hangs. The guide roller 13 is mounted in a slide 18, which is easily installed in the rear corner area before assembly of the grid frame 7. The cable 14 is guided in the slide 18 so that it passes through the Counterweight 17 is pulled on an approximately vertical path. The preferably flocked counterweight 17 is adapted to the cross section of the profile groove 8 'in the longitudinal profile 8 and thus guided therein frictionless and quiet. At the upper end of the door in the profile groove 8 'of the cable 14 is deflected by the guide roller 13 so that it is stretched approximately horizontally with the grid open.

Wie aus Fig. 2 ersichtlich, ist der Gleitschieber 18 im Gitterrahmen 7 beim Gehrungsschnitt 19 positioniert. Dadurch ist es gemäss dem erfindungsgemässen Verfahren möglich, den Gleitschieber 18 mit der Umlenkrolle 13, dem Seilzug 14 und dem Gegengewicht 17 vor dem Zusammenbau des Gitterrahmens 7 in das Rahmenprofil 8 einzuschieben und danach die Rahmenteile beim Gehrungsschnitt zusammenzumontieren.How out Fig. 2 can be seen, the slider 18 is positioned in the lattice frame 7 at the miter cut 19. Thereby, it is possible according to the inventive method, slide the slider 18 with the guide roller 13, the cable 14 and the counterweight 17 before assembling the grid frame 7 in the frame section 8 and then assemble the frame parts miter cut.

Der Gleitschieber 18 weist ausserdem ein oben leicht ausstehendes U-Profil 20 auf zur Aufnahme eines sich längs der Laufschiene 12 erstreckenden Führungsstegs 21.The slide valve 18 also has a slightly upstanding U-profile 20 for receiving a longitudinally extending guide rail 12 along the guide rail 21st

Zum Öffnen der Schiebetür 2 ist diese leicht von Hand mit Hilfe eines Handgriffes 22 verschiebbar. Wird in der Offenstellung die Schiebetür losgelassen, erfolgt dann sofort selbsttätig die Aktivierung der Betätigungseinrichtung 5, und diese schiebt verzögerungsfrei die Schiebetür 2 in die Schliessstellung wieder zurück, weil das Gegengewicht 17 den Seilzug 14 herunterzieht und mit seiner Schwerkraft eine Kraftkomponente erzeugt, die auf den Gleitschieber 18 und damit den Gitterrahmen 7 in Schliessrichtung wirksam wird.To open the sliding door 2, this is easily displaced by hand by means of a handle 22. If the sliding door is released in the open position, the activation of the actuating device 5 then takes place automatically, and this pushes the sliding door 2 back into the closed position without delay because the counterweight 17 pulls down the cable 14 and generates with its force of gravity a force component which is on the Slider 18 and thus the grid frame 7 in the closing direction is effective.

In der annähernden Schliessstellung der Schiebetür 2, wie in Fig. 1 veranschaulicht ist, befindet sich das an der Laufschiene befestigte Ende 15 des Seilzugs 14 oberhalb der Schiebetür auf der Seite dieser Betätigungseinrichtung 5. Damit kann der Seilzug kurz gehalten werden. Zudem verläuft der Seilzug 14 auch in der geschlossenen Türposition vorteilhaft mit einem Winkel zu seiner übrigen annähernd vertikalen Ausdehnung, damit dieser bei der Umlenkrolle 13 stets eine in Schliessrichtung wirkende Kraftkomponente erzeugt.In the approximate closed position of the sliding door 2, as in Fig. 1 is illustrated, is attached to the running rail end 15 of the cable 14 above the sliding door on the side of this actuator 5. Thus, the cable can be kept short. moreover extends the cable 14 in the closed door position advantageously at an angle to its remaining approximately vertical extent, so that it always generates a force acting in the closing direction force component in the deflection roller 13.

Das erfindungsgemässe Insektenschutzgitter zeichnet sich insbesondere dadurch aus, dass die Einrichtung zum Selbstschliessen des Gitters rein mechanisch funktioniert, selbsttätig aktiviert wird und zudem wenige robuste Beuteile aufweist, die einen wirtschaftlich günstigen Aufbau ermöglichen und dauerhaft eine hohe Funktionssicherheit gewährleisten. Beim beschriebenen Ausführungsbeispiel ist das Insektenschutzgitter zweiteilig. Je nach Grösse der zu schützenden Wandöffnung ist es aber auch ohne weiters in Rahmen der Erfindung möglich, die vorstehend beschriebene Betätigungseinrichtung 5 sowohl in einteilige als auch in drei- oder mehrteilige Insektenschutzgitter unter Berücksichtigung der jeweiligen Schliessrichtung einzubauen. Sie kann auch nachträglich ohne grossen Aufwand in vorhandene Schutzgitter eingebaut werden.The inventive insect screen is characterized in particular by the fact that the device for self-closing of the grid works purely mechanically, is automatically activated and also has few robust baggage that allow a low-cost construction and permanently ensure high reliability. In the described embodiment, the insect screen is in two parts. Depending on the size of the wall opening to be protected, however, it is also readily possible within the scope of the invention to install the actuating device 5 described above both in one-piece and in three-part or multi-part insect screens taking into account the respective closing direction. It can also be retrofitted without great effort into existing protective grid.

Die Erfindung ist ebenfalls bei Insektenschutzgittern mit anders ausgestalteten Laufbahnen anwendbar, etwa bei Gittern, die auf der oberen Laufschiene aufgehängt sind, oder aber bei Gittern, deren obere Laufschiene mit Gleitrollen anstelle des Führungssteges 21 versehen ist.The invention is also applicable to insect screens with differently designed raceways, such as bars, which are suspended on the upper track, or in lattices whose upper track is provided with rollers instead of the guide bar 21.

Die Erfindung ist mit den oben erläuterten Ausführungsbeispielen ausreichend dargetan. Sie liesse sich jedoch noch in anderen Varianten darstellen. So könnte die Betätigungseinrichtung 5 im Prinzip auch mit Federkraft anstelle durch Ausnutzung der Schwerkraft betrieben werden, wobei diese Ausgestaltung jedoch nicht zur vorliegenden Erfindung gehört.The invention is sufficiently demonstrated with the embodiments explained above. However, it could be represented in other variants. Thus, the actuator 5 could in principle also be operated with spring force instead of using gravity, but this embodiment does not belong to the present invention.
