Description

Titel: FenstergitterTitle: Window grille

Ia zunehmendem Maße besteht in Vohn-und Geschäftsgebäuden Bedarf für eine Fenstersicherung gegen Einbruch in Form von Fenstergittern.There is an increasing need for window security against burglary in the form of window grilles in residential and commercial buildings.

Um die Kosten eines Gittereinbaus gering zu halten, sucht der Anwender eine Möglichkeit die Montage dieser Fenstergitter selbst v'arzu&ehmen, Es stellt sich jedoch heraus, daß der Endverbraucher die Bearbeitung von Metall , wie sägen, biegen , bahren una insbesondere schweißen nur in seltenen Fällen selbst beherrscht.In order to keep the costs of installing grilles low, the user looks for a way to install these window grilles himself. However, it turns out that the end user is only rarely able to work with metal, such as sawing, bending, shaping and especially welding.

Außerdem z-eigt es sich immer wieder, daß Xetallgitter nach d.er Kontage in Kauerwerk durch die Temeraturschwankungen einer stäi. igen Belastung im Bereich der mit dem Mauerwerk verbundenen Stellen aufweist, was dazu führt, daß sich eingemauerte Gitterstäbe im Laufe der Zeit lösen können.In addition, it has been shown time and again that metal gratings after exposure to masonry are subjected to constant stress due to temperature fluctuations in the areas connected to the masonry, which means that the embedded grating bars can become loose over time.

Die befeaant« und eiaiaciist^ Lösung bietet hier da-s Einsetzen von Ifctallstangea in regemnäSigera Abfänden zueinander iß das Mauerwerk.The most important and practical solution here is to insert concrete rods at regular intervals from one another into the masonry.

Jedoch muß der Anwecar hier die ??-+..allstangen zusagen und das Mauerwerk aufbrechen, um die '«etallstäbe hier mindes* i rs auf jeder Seite 10 cm tief eiBzolassen.However, the contractor must cut the metal rods and break open the masonry in order to allow the metal rods to penetrate at least 10 cm deep on each side.

Es stellt sich daher die Aufgabe, ein Fenstergitter vorzugsweise zur Hontage /on außen, vorzustellen, das eine einfache Lösung für die vorgenannten Punkte bietet.The task therefore arises to present a window grille, preferably for mounting on the outside, which offers a simple solution to the above-mentioned points.

Das erfindungsg-jniäße Fenstergitter löst diese Punkte in der Form, daß das Fenstergitter au* 2 einzelnen U- förmingen Metallprofilen besteht, die nach einem Zusammenstecken der beiden U-Teile in vorhandene Löcher, sich gegenseitig halten und führen.( Abb. 1-2) Di*?■■■« zusammen gesteckten U-Profile können so zwischen die Mauerlaibungen geführt werden, es können mit einen Bohrer die nötigen Löcher in beliebiger Tiefe gebohrt werden ,und so können die Gitterstäbe direkt in die mit Zementspeis gefüllten Löcher auf beiden Seiten gleichzeitig eingeschoben werden.The window grille according to the invention solves these problems in that the window grille consists of two individual U-shaped metal profiles, which hold and guide each other after the two U-parts are put together in existing holes. (Fig. 1-2) The U-profiles put together can be guided between the wall reveals, the necessary holes can be drilled to any depth using a drill, and the grille bars can be pushed directly into the holes filled with cement on both sides at the same time.

Es wird kein zuätzliches Material wie Schrauben, Dübel benötigt.No additional material such as screws or dowels is required.

Das so montierte Metallgitter bildet bei Temperaturschwankungen keine Spannungen auf der Längsachse des Metalls.The metal grid mounted in this way does not create any stresses on the longitudinal axis of the metal when there are temperature fluctuations.

Außerdem bietet diese zusammensteckbare Form die Möglichkeit U- Elemente mit unterschiedlichen Schenkellängen direkt bei der Montage zu wählen und zu montieren.In addition, this interlocking form offers the possibility of selecting and assembling U-elements with different leg lengths directly during assembly.

Außerdem ist es möglich direkt bei der Montage Metallhülsen entsprechend den sich hier ergebenen Abständen aufzusetzen.(Abb,8)und so einem erhöhtem Sicherheitsbedarf individuell nachzukommen.It is also possible to attach metal sleeves directly during assembly according to the resulting distances (Fig. 8) and thus meet increased safety requirements individually.

Diese Metallhülsen erhöhen die Durchbruchsicherheit, da sich die losen Metallhülsen bei dem Versuch diese zu durchsägen mitdrehen.These metal sleeves increase the resistance to penetration, as the loose metal sleeves rotate when an attempt is made to saw through them.

Diese Form des Metallgitters gibt die Möglichkeit die Einbautiefe der Metallstangen direkt vor Ort bei der Montage festzulegen und somit auch die Gestaltung der Abstände der Grundelemente festzulegen,was für die folgende Montage der verschiedenen Dekorelemente(Abb. 12 +13)wichtig ist.This form of metal grid makes it possible to determine the installation depth of the metal rods directly on site during assembly and thus also to determine the design of the distances between the basic elements, which is important for the subsequent assembly of the various decorative elements (Fig. 12 + 13).

Di§ Ausführung dieses Grfindungsgemäßen Metallgitters gibt die Möglichkeit die Endstücke zur Einbringung in das Mauerwerk in den verschiedensten Formen auszuführen, ( Abb. 3,4,5,6,7,8) sodaß eine nachThe design of this metal grid according to the invention provides the possibility of designing the end pieces for insertion into the masonry in a variety of shapes (Fig. 3,4,5,6,7,8) so that

der Hontage nicht mehr erkennbare Sicherung der Verbindung zwischen Hauerwerk und Hetallstab vorgenommen werden kann.sodaß eine Vorbereitung eines evenuellen Einbrechers auf bekannte Sicherungselemente wie so genannte Sicherheitsschrauben nicht möglich ist. .The connection between the hammer and the metal rod can be secured in a way that is no longer visible during assembly, so that a potential burglar cannot prepare for known security elements such as so-called security screws.

Weiterhin bietet diese Ausführung des Erfindungsgemäßen Hetallgitters die Höglichkeit die Länge der Sicherungsstäbe je nach Bedarf zu verändern sowie diese Verlängerung dazu zu nutzen, dem Gitter gebogene Endstücks auf zusetzen, sodaß das Fenstergitter auch in der Form montiert werden kann, daß das Gitter außerhalb ··.?.«r iiiiuerlaibur:g von außen aufgesetzt werden kann, insbeondere dann, wenn Fensterflügel nach außen geöffnet werden , und somit noch die Höglichkeit geboten ist das Fenster trotzt Gitter teilweise zu öffnen,was bei einer Montage zwischen den Hauerlaibungen gar nicht oder nur sehr gering möglich ist.( Abb.7,8) Eine weiter Form der dekorativen Gestaltung zeigt die Abb. 10 +11 wobei die Dekorelemente dem Bedürfnis des Anwenders nach ind:^; ./idueller Gestaltung dieses nach auRen sichtbaren Fenstergitters Rechnung trägt, und einen wesentlichen Teil des erfindungsgemäßen Fenstergitters darstellt, da die Bereitschaft Fenstergitter zu montieren wesentlich auch von der dekorativen Gestaltung abhängt.Furthermore, this design of the metal grille according to the invention offers the option of changing the length of the security bars as required and of using this extension to add a curved end piece to the grille, so that the window grille can also be installed in such a way that the grille can be installed outside the outer frame, particularly when window sashes are opened outwards, and thus it is still possible to partially open the window despite the grille, which is not possible or only very limited when installed between the window reveals. (Fig. 7, 8) Another form of decorative design is shown in Fig. 10 + 11, where the decorative elements take into account the user's need for ^an individual design of this externally visible window grille and represent an essential part of the window grille according to the invention, since the willingness to install window grilles also depends significantly on the decorative design.
