Abstract
Description
Die Erfindung betrifft eine Schutzeinrichtung für Kraftfahr zeugfenster, bestehend aus einer Glasscheibe und einer unter Einhaltung eines Zwischenraumes mit dieser verbundenen, aus tauschbaren Vorsatzscheibe aus einem transparenten, hoch schlagzähen Kunststoff.The invention relates to a protective device for motor vehicles witness window, consisting of a glass pane and an under Compliance with a gap associated with this, from interchangeable front lens made of a transparent, high impact-resistant plastic.
Zur Verbesserung der mechanischen Widerstandsfähigkeit von Glasscheiben bei Fahrzeugen ist es bekannt, Kunststoffschei ben aus Polycarbonat als Schutzelemente vor die Frontscheibe, insbesondere bei Einsatzfahrzeugen der Polizei zu schrauben. Dadurch soll verhindert werden, daß Schläge mit Werkzeugen, Steinwürfe und Geschosse aus Schleudern die Glasscheiben eines Fahrzeugs, insbesondere die Frontscheibe, verletzen oder gar durchdringen und das Einsatzfahrzeug stillegen bzw. die das Fahrzeug führenden Personen gefährden.To improve the mechanical resistance of Glass panes in vehicles are known to be plastic panes made of polycarbonate as protective elements in front of the windscreen, to screw especially in police vehicles. This is to prevent blows with tools, Throwing stones and projectiles from slingshots the glass panes of one Vehicle, especially the windscreen, injure or even penetrate and shut down the emergency vehicle or that Endanger people driving the vehicle.
Zwischen einer vorgeschraubten Schutzscheibe und der Kfz-Glas scheibe besteht ein Luftzwischenraum, der technisch nicht be herrschbar ist. Im Winter führt Kondensatbildung zu starker Sichtbehinderung, die nicht zu beseitigen ist. Bei Einsätzen kann durch gewalttätige Demonstranten zwischen die schützende Polycarbonatscheibe und die Fensterscheibe flüssige Farbe, ätzendes und anderes die Durchsicht hemmendes Material ge bracht werden. Außerdem weist das System Glasscheiben-Luftzwi schenraum-Kunststoffscheibe vier reflektierende Oberflächen auf, die bei der hohen Brechzahl des Polycarbonats von n D = 1,58 den Lichttransmissionsgrad allein durch Reflexion um ca. 18% verringern. In Verbindung mit Staub und Schmutz und der Extinktion beider Scheiben sinkt so der Lichttrans missionsgrad des Frontscheibensystems unter 65% und damit unter einen zulässigen Bereich.There is an air gap between a pre-screwed protective pane and the automotive glass pane, which is technically impossible to control. In winter, the formation of condensate leads to severe visual impairment, which cannot be removed. During operations, violent demonstrators can bring liquid paint, caustic and other materials that obscure view between the protective polycarbonate pane and the window pane. In addition, the glass pane-air space-plastic pane has four reflective surfaces, which reduce the light transmittance by reflection by approx. 18% due to the high refractive index of the polycarbonate of n D = 1.58. In connection with dust and dirt and the extinction of both panes, the light transmittance of the windscreen system drops below 65% and thus below a permitted range.
Der Erfindung liegt die Aufgabe zu Grunde, eine Schutzeinrich tung nach dem eingangs genannten Gattungsbegriff so auszubil den, daß der Lichttransmissionsgrad durch reflektierende Ober flächen des Scheibensystems nicht wesentlich negativ beein flußt wird. Außerdem sollen Sichtbehinderungen durch die Bil dung von Kondensat ausgeschlossen werden.The invention is based on the object of a protective device training according to the generic term mentioned above the that the light transmittance by reflective Ober surfaces of the disc system are not significantly negatively affected is flowing. In addition, the Bil condensate.
Die Erfindung als Lösung dieser Aufgabe zeichnet sich durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale aus. Die hierdurch erzielbaren Vorteile bestehen insbesondere da rin, daß statt der schwierigen Anbringung einer üblichen Vor satzscheibe mit zusätzlichem Halterahmen, der Vereisungs- und Verschmutzungsmöglichkeiten des Luftzwischenraumes und der mangelhaften Sichtbedingungen im Sichtbereich, durch die erfindungsgemäße Schutzeinrichtung eine Verbund scheibe mit optischen und mechanischen Vorteilen vorliegt. Durch die einige Millimeter dicke Weichharzschicht zwischen den Scheiben wird die Schutzwirkung der Polycarbonatplatte er heblich gesteigert. Die Fahrzeuginsassen werden somit wirkungs voller geschützt. Außerdem besteht die überraschende Möglich keit, bei nicht mehr vertretbaren Oberflächenbeschädigungen der Vorsatzscheibe diese gegen eine neue Kunststoffscheibe auszutauschen, da die niedrige Zugfestigkeit der gelartigen Gießharzschicht ein Abziehen der Vorsatzscheibe zuläßt und damit erstmalig eine Schutzscheiben-Verbundkombination mit aus tauschbarem Verschleißteil vorliegt.The invention as a solution to this problem is characterized by the features specified in the characterizing part of claim 1. The advantages that can be achieved in this way exist in particular rin that instead of the difficult attachment of a usual front set disc with additional holding frame, the icing and Possibilities of pollution of the air gap and the poor visual conditions in the field of vision, a composite by the protective device according to the invention disc with optical and mechanical advantages. Due to the few millimeter thick layer of soft resin between the glass will protect the polycarbonate sheet significantly increased. The vehicle occupants are thus effective fully protected. There is also the surprising possibility speed, if surface damage is no longer justifiable the front lens against a new plastic lens exchange because of the low tensile strength of the gel-like Cast resin layer allows pulling off the front lens and for the first time a combination of protective glass panes exchangeable wear part is present.
Das Verfahren zur Herstellung des erfindungsgemäßen Verbund systems erfordert lediglich das Verformen der Kunststoff scheibe zur Anpassung an die Wölbung der Glasscheibe des Fahrzeugs, das Anbringen des Distanz- und Dichtungsbandes auf der Glasscheibe, das Aufsetzen der Kunststoffscheibe auf das Distanz- und Dichtungsband und dessen Versiegelung gegen beide Scheiben und das Füllen des Luftzwischenraumes zwischen beiden Scheiben durch eine im oberen Bereich angeordnete Öff nung mit dem gelartig polymerisierenden Gießharz.The process for producing the composite according to the invention systems only requires the plastic to be deformed pane to adapt to the curvature of the glass pane of the Vehicle, attaching the spacer and sealing tape on the glass pane, putting the plastic pane on the spacer and sealing tape and its sealing against both washers and filling the air gap between two panes by an opening arranged in the upper area with the gel-like polymerizing cast resin.
Weitere Merkmale zur vorteilhaften Gestaltung des Erfindungs gegenstandes sind in den Unteransprüchen angegeben.Further features for the advantageous design of the invention subject matter are specified in the subclaims.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung im Querschnitt schematisch dargestellt und nachstehend erläutert.In the drawing, an embodiment of the invention is in Cross section shown schematically and explained below.
Eine Kraftfahrzeugverbundglasscheibe 1 ist üblicherweise im eingebauten Zustand mit ihrem Rand in einer umlaufenden Gummi dichtung 2 gelagert. Auf der Glasscheibe 1 ist ein Rahmen aus einem umlaufenden Distanz- und Dichtungsband 3 angeordnet. Auf dessen Außenseite ist eine Kunststoffscheibe 4 aus Poly carbonat gesetzt. Das umlaufende Distanz- und Dichtungsband 3 ist bei 5 umlaufend sowohl gegen die Glasscheibe 1 als auch gegen die Kunststoffscheibe 4 versiegelt. Der Zwischenraum zwi schen den beiden Scheiben ist mit einem zu einem gelartigen Zustand polymerisierenden Gießharz 6 ausgefüllt. Dadurch er gibt sich ein kompaktes Schichtensystem aus der Glasscheibe 1, der Gießharzschicht 6 und der Kunststoffscheibe 4, das eine wesentlich höhere mechanische Sicherheit gegen Beschädigun gen oder Zerstörungen durch gewaltsame mechanische Einwirkun gen bietet als die bisherigen Ausführungen. Es fehlt ein Zwischenraum mit den vorgenannten Nachteilen, die zu einer Sichtbehinderung führen könnten.A motor vehicle laminated glass pane 1 is usually mounted with its edge in a circumferential rubber seal 2 in the installed state. A frame made of a circumferential spacer and sealing strip 3 is arranged on the glass pane 1 . On the outside is a plastic disc 4 made of poly carbonate. The circumferential spacer and sealing tape 3 is sealed circumferentially at 5 both against the glass pane 1 and against the plastic pane 4 . The space between the two disks is filled with a resin 6 polymerizing to a gel-like state. This gives it a compact layer system consisting of the glass pane 1 , the cast resin layer 6 and the plastic pane 4 , which offers a substantially higher mechanical security against damage or destruction by violent mechanical influences than the previous versions. There is no space with the aforementioned disadvantages, which could lead to a visual impairment.
