Description
Beschußfeste Verglasung Die Erfindung bezieht sich auf eine beschußfeste Verglasung, die aus mehreren aneinander anliegenden bzw.Bulletproof glazing The invention relates to bulletproof glazing Glazing made up of several adjoining or
miteinander verbundenen lichtdurchlässigen Scheiben besteht.interconnected translucent panes consists.
Beschußfeste Verglasungen aus mehreren miteinander verbundenen oder aneinander anliegenden lichtdurchlässigen, insbesondere durchsichtigen Scheiben sind heute in großem Umfang im Einsatz,und zwar insbesondere in Bereichen von Geldinstituten, um derart einerseits das ungestörte Beobachten aller Vorgänge sowohl von innerhalb der Kasse nach außerhalb der Kasse, wie auch von außerhalb nach innerhalb der Kasse zu ermöglichen, andererseits aber dem über das Geld verfügenden Kassierer die erforderliche Sicherheit zu geben.Bulletproof glazings made of several interconnected or adjoining translucent, in particular transparent panes are in use today on a large scale, especially in areas of financial institutions, On the one hand, the undisturbed observation of all processes from within the cash register to outside the cash register, as well as from outside to inside the To enable cash register, but on the other hand the cashier who has the money to give the necessary security.
Weiterhin sind derartige beschußfeste Einrichtungen auch in anderen öffentlichen Institutionen bekannt und es ist schließlich denkbar, daß derartige Einrichtungen auch in entfernt liegende Wohnhäuser o.dgl. als Fenster eingebaut werden, um derart die Inhaber vor Einbrüchen und Uberfällen zu schützen.Furthermore, such bulletproof facilities are also in others known to public institutions and it is finally conceivable that such Facilities also in remote residential buildings or the like. built in as a window in order to protect the owners from break-ins and robberies.
Im Prinzip bestehen die bisher bekannten Konstruktionen aus mehreren miteinander verbundenen oder dicht aneinander anliegenden dicken Glasscheiben, die, um die erforderliche Beschußfestigkeit zu erreichen, eine erhebliche Dicke und damit ein erhebliches Gewicht aufweisen müssen. Dies führt in vielen Fällen zu Konstruktionsschwierigkeiten, da die die Scheiben tragenden Unterkonstruktionen entsprechend stark dimensioniert werden müssen.In principle, the previously known constructions consist of several thick panes of glass that are connected to one another or close to one another, which, in order to achieve the required bullet resistance, a considerable thickness and thus must be of considerable weight. In many cases this leads to construction difficulties, because the substructures supporting the panes are correspondingly large Need to become.
Es ist auch bekannt geworden, beschußfeste Verglasungen aus Scheiben aus Polymethacrylsäureester , sogenanntem Acrylglas, herzustellen, das den Vorteil hat, nur ein spezifisches Gewicht von 1,18 aufzuweisen, so daß es damit nur etwa halb so schwer wie normales Fensterglas ist.Bulletproof glazing made from panes has also become known from polymethacrylic acid ester, so-called acrylic glass, which has the advantage has to have a specific gravity of 1.18, so that it is only about half as heavy as normal window glass.
Die bei diesen Scheiben in Kauf zu nehmende Stärke, um die erforderliche Beschußfestigkeit zu erreichen, stört aber in vielen Einsatzbereichen.The strength to be accepted with these discs in order to achieve the required Achieving bullet resistance, however, interferes in many areas of application.
Der Erfindung liegt die Aufgabe zugrunde, eine beschuR-feste Verglasung zu erstellen, die bei einem gleichen Beschußfestigkeitswert wie Acrylglas oder Silikatglas wesentlich leichter und dünner hergestellt werden kann, so daß die Einsat zmöglichkeiten- erheblich vergrößert werden und außerdem die Handhabung dieser Scheiben erleichtert wird.The invention is based on the object of a BeschuR-proof glazing to create that with the same bullet resistance value as acrylic glass or silicate glass can be made much lighter and thinner, so that the possible uses can be significantly enlarged and also facilitates the handling of these disks will.
Die Lösung der der Erfindung zugrundeliegenden Aufgabe kennzeichnet sich durch die Kombination einer auf der beschußgefährdeten Seite der Verglasung angeordneten, aus Polymethacrylsäureester (Acrylglas) bestehenden Scheibe mit einer auf ihrer Rückseite angeordneten Scheibe aus Polycarbonat.The solution to the problem on which the invention is based characterizes by combining one on the bullet-prone side of the glazing arranged, made of polymethacrylic acid ester (acrylic glass) existing pane with a Polycarbonate disc arranged on its rear side.
In überraschender Weise wurde gefunden, daß, wenn die an sich seit langem zum Stande der Technik gehörenden Polycarbonatscheiben auf die Rückseite einer Scheibe aus Acrylglas aufgebracht werden, eine beschußfeste Scheibe geschaffen werden kann, die gegenüber den bisher bekannten Acrylglasscheiben erheblich dünner ausgebildet werden kann, wobei die auf der Rückseite der Acrylglasscheibe aufzubringende Polycarbonat scheibe beispielsweise nur eine Stärke von 1 mm aufzuweisen braucht.Surprisingly, it was found that if the in itself since Polycarbonate panes, which have long been part of the state of the art, on the back a pane of acrylic glass are applied, a bullet-proof pane is created which can be considerably thinner compared to the previously known acrylic glass panes can be formed, with the one to be applied to the back of the acrylic glass pane Polycarbonate Disk, for example, only needs to have a thickness of 1 mm.
Gegenüber den bisher zum Stand der Technik gehörenden beschußfesten Scheiben wird durch diese erfindungsgemäße Kombination eine sehr leichte, voll durchsichtige und voll lichtdurchlässige Scheibe erreicht, die der Konstruktion neue Möglichkeiten gibt und die den Einsatz dieser Scheiben auch in weiten Bereichen ermöglicht, die bisher aus Kostengründen nicht mit beschußfestem Sicherheitsglas ausgerüstet werden konnten.Compared to the bulletproof ones that were previously part of the state of the art This combination according to the invention makes panes very light, fully transparent and fully translucent pane that opens up new possibilities for construction there and which enables the use of these discs in a wide range of areas so far have not been equipped with bulletproof safety glass for cost reasons could.
Gemäß einer ersten Ausführungsform der Erfindung wird vorgeschlagen, daß die Polycarbonat scheibe an der Acrylglasscheibe dicht anliegend angeordnet wird, wobei es nicht erforderlich ist, daß die beiden Scheiben fest miteinander verbunden sind, sondern es reicht aus, wenn die Scheiben beispielsweise am Rand miteinander zusammengefaßt werden.According to a first embodiment of the invention, it is proposed that that the polycarbonate disc is arranged close to the acrylic glass is, it is not necessary that the two discs firmly together are connected, but it is sufficient if the discs, for example, at the edge be summarized with each other.
Gemäß einer anderen Ausführungsform wird vorgeschlagen, daß die Polycarbonatscheibe mit der Acrylglasscheibe fest verbunden ist, beispielsweise durch Verkleben oder sonstige chemische Verfahren, so daß ein inniger und dichter Verbund der beiden Scheiben erreicht wird.According to another embodiment it is proposed that the polycarbonate pane is firmly connected to the acrylic sheet, for example by gluing or other chemical processes, so that an intimate and tight bond between the two Discs is achieved.
Wie bereits vorstehend ausgeführt, ist ein weiterer Vorschlag der Erfindung darin zu sehen, daß die Polycarbonatscheibe eine wesentlich geringere Stärke als die Acrylglasscheibe aufweist, wobei diese Maßnahme als ein wesentliches Merkmal der Erfindung zu betrachten ist.As stated above, another proposal is the The invention can be seen in the fact that the polycarbonate pane is a much smaller one Has strength than the acrylic sheet, this measure as an essential Feature of the invention is to be considered.
Ein Ausführungsbeispiel der Erfindung wird zur Verdeutlichung des Erfindungsgedankens nachfolgend anhand der Zeichnung erläutert.An embodiment of the invention is to illustrate the The inventive idea explained below with reference to the drawing.
In der Zeichnung sind ohne Bindung an einen bestimmten Maßstab zwei aneinander'anliegende Scheiben dargestellt, wobei die Scheibe aus Acrylglas mit i und die Polycarbonatscheibe mit 2 bezeichnet ist. Die Scheiben können einfach dicht aneinanderliegen oder beispielsweise über chemische Verbindungen oder Klebemittel fest miteinander verbunden sein Wesentlich ist bei der erfindungsgemäßen Anordnung, daß die Acrylglasscheibe an der beschußgefährdeten Seite der beschußfesten Verglasung angeordnet ist, d.h., bei einem eventuellen Beschuß muß die Kugel erst die Acrylglasscheibe durchdringen und wird dann höchstwahrscheinlich durch die elastischere Polycarbonat scheibe aufgefangen, nachdem sie bereits ihre Anfangsenergie in der Acrylglasscheibe abgegeben hat.In the drawing, there are two without being tied to any particular scale shown adjacent panes, the pane made of acrylic glass with i and the polycarbonate pane is denoted by 2. The discs can simply close together or, for example, via chemical compounds or adhesives be firmly connected to each other It is essential in the arrangement according to the invention, that the acrylic glass pane is on the bulletproof side of the bulletproof glazing arranged, i.e. in the event of a shot, the bullet must first pass the acrylic glass pane penetrate and will then most likely through the more resilient polycarbonate disc captured after it has already received its initial energy in the acrylic sheet has submitted.
Für die Erfindung ist es nicht wesentlich, aus welchen chemischen oder physikalischen Gründen die erfindungsgemäße Kombination den angestrebten Erfolg erreicht.For the invention it is not essential from which chemical or physical reasons, the combination according to the invention achieves the desired success achieved.
