Abhängig von einem jeweils geltenden Anforderungsprofil, werden Rail vehicle having at least two spaced and stacked discs. Glazings for rail vehicles are known in the art in various embodiments. Depending on a current requirement profile, will be
Einscheibensicherheitsglas , Verbundsicherheitsglas , Tempered safety glass, laminated safety glass,
druckdichte, schallgedämpfte oder doppelverglaste Systeme verwendet. Besonders für Hochgeschwindigkeitsfahrzeuge hat sich eine Doppelverglasung durchgesetzt. Dabei bestehen die zwei eingesetzten Scheiben jeweils aus pressure-tight, silenced or double-glazed systems used. Especially for high speed vehicles, a double glazing has prevailed. In this case, the two discs used each consist of
Verbundsicherheitsglas, während sich zwischen den einzelnen Scheiben entweder Luft oder ein Gas befindet, welches Laminated safety glass, while between the individual slices is either air or a gas, which
Isolierglaseigenschaften dieser Verglasung verbessert. Insulating glass properties of this glazing improved.
Aufgrund der Vielzahl zu erfüllender Anforderungen bezüglich akustischer und thermischer Eigenschaften sowie Due to the large number of requirements to be met regarding acoustic and thermal properties as well as
erforderlicher Festigkeit sind solche Verglasungen required strength are such glazings
vergleichsweise schwer. Darüber hinaus besteht selbst beicomparatively difficult. In addition, there is even at
Verwendung von Verbundsicherheitsglas eine erhebliche Gefahr, dass Fenster durch Vandalismus zerstört werden können. Use of laminated safety glass a significant risk that windows can be destroyed by vandalism.
Zwar sind im Stand der Technik auch typischer Weise als einzelne Scheibe vorliegende Kunststoffverglasungen bekannt. Diese werden jedoch als problematisch im Hinblick auf Although in the prior art also typically available as a single disc plastic glazes are known. These, however, are considered problematic with regard to
unterschiedliche Wärmeausdehnungskoeffizienten zwischen different thermal expansion coefficients between
Kunststoff und Rohbau, Brandschutzeigenschaften, Lebensdauer aufgrund von UV-Bestrahlung und Sandbeaufschlagung angesehen. Auch hinsichtlich einer zulässigen Durchbiegung einer Plastics and shell, fire protection properties, life due to UV irradiation and sand treatment considered. Also with regard to a permissible deflection of a
Kunststoffverglasung im Betriebseinsatz ergeben sich Plastic glazing in operational use arise
Vorbehalte . Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, die eingangs genannte Verglasung derart weiterzuentwickeln, dass sich leichtere und Crash-sicherere Fenster für Reservations. Proceeding from this, the present invention seeks to further develop the above-mentioned glazing such that lighter and more crash-safe windows for
Schienenfahrzeuge ergeben. Rail vehicles result.
Diese Aufgabe wird dadurch gelöst, dass die eine Scheibe der Verglasung aus einem Sicherheitsglas und die andere Scheibe aus einem Kunststoff gebildet ist, wobei die beiden Scheiben über elastische Abstandshalter miteinander verbunden sind. Dabei wird typischer Weise die Scheibe aus Sicherheitsglas auf einer Innenseite eines mit der Verglasung ausgestatteten Schienenfahrzeugs verwendet, während die Scheibe aus This object is achieved in that the one pane of the glazing is made of a safety glass and the other pane is made of a plastic, wherein the two panes are connected to one another via elastic spacers. Typically, the pane of safety glass is used on an inside of a glazed rail vehicle while the pane is off
Kunststoff außen liegt. Aufgrund dieser Ausgestaltung der Verglasung mit einer Glasscheibe und einer KunststoffScheibe ergibt sich ein vermindertes Gewicht der Verglasung. Die typischer Weise innen liegende Scheibe aus Sicherheitsglas bringt eine erforderliche Kratzfestigkeit bei Plastic is outside. Due to this configuration of the glazing with a glass pane and a plastic disc results in a reduced weight of the glazing. The typically internal pane of safety glass provides a required scratch resistance
Vandalismuseinwirkung mit sich, während die äußere Scheibe gewichtssparend aus Kunststoff besteht. Vandalism with it, while the outer disc weight saving plastic.
Die eine Scheibe der Verglasung kann beispielsweise aus einem Einscheibensicherheitsglas oder einem Verbundsicherheitsglas gebildet sein. Die andere Scheibe, die typischer Weise außen am Fahrzeug vorliegen wird, ist aus einer thermoplastischen Formmasse gebildet. Als Materialbeispiele kommen Acrylglas oder Makroion® in Frage. The one pane of the glazing may, for example, be formed from a toughened safety glass or a laminated safety glass. The other disk, which will typically be on the outside of the vehicle, is formed from a thermoplastic molding compound. Possible examples of materials are acrylic glass or Makroion®.
Die Kunststoffscheibe kann auf ihrer nach außen gerichteten Seite mit einer kratzfesten Schicht versehen sein, um auch hier eine Widerstandsfähigkeit gegen Vandalismus zu bewirken. The plastic disc may be provided on its side facing outward with a scratch-resistant layer, in order to bring about a resistance to vandalism here.
Die elastischen Abstandshalter ermöglichen es, den The elastic spacers allow the
unterschiedlichen Wärmeausdehnungskoeffizienten der different thermal expansion coefficient of the
Materialien, aus denen die wenigstens zwei Scheiben gebildet sind, Rechnung zu tragen. Die Abstandshalter sind bevorzugt aus einem thermoplastischen Kunststoff gebildet. Insgesamt ergeben sich für die Verglasung im Vergleich zum Stand der Technik Gewichtsvorteile, da die Dichte von Materials from which the at least two discs are formed to take into account. The spacers are preferably formed from a thermoplastic material. Overall, there are weight advantages for the glazing compared to the prior art, since the density of
Kunststoff im Vergleich zu Glas wesentlich niedriger ist. Da Kunststoffe eine wesentlich höhere Zähigkeit aufweisen als Glas, welches eher ein sprödes Verhalten zeigt, ist die Plastic is much lower compared to glass. Since plastics have a much higher toughness than glass, which rather shows a brittle behavior, is the
Gefahr einer Zerstörung geringer. Danger of destruction lower.
Die insgesamt erhöhte Beständigkeit der Verglasung gegenüber Vandalismus ermöglicht eine höhere Verfügbarkeit der mit der Verglasung ausgestatteten Schienenfahrzeuge in deren Betrieb. The overall increased resistance of the glazing to vandalism allows a higher availability of the glazed rail vehicles in their operation.
