Description

Fernglas mit Schutzüberzug Es ist seit langem üblich, die Gehäuseteile von Ferngläsern zum Schutz gegen Schlag, Kratzer, Korrosion u. dgl. mit einem Lederüberzug zu versehen.Binoculars with Protective Cover It has long been common practice to cover the housing parts of binoculars to protect against impact, scratches, corrosion and the like with a leather cover to provide.

Erfindungsgemäß wurde -überraschend gefunden, daß Ferngläser schwimmfähig gemacht werden können, wenn an Stelle des bekannten Lederüberzuges Schutzüberzüge aus einem Material mit geeignet geringem spezifischem Gewicht verwendet werden. Auf diese Weise wird es möglich, das Gewicht des Glases, bezogen auf sein Gesamtvolumen, zumindest so weit herabzusetzen, daß das Glas im Wasser schwebt. Während es ganz allgemein von Nutzen ist, Ferngläser so leicht wie möglich zu machen, da hierdurch Ermüdungen bei Benutzung des Glases mit freier Hand weitestgehend vermieden werden, ist die Schwimmfähigkeit des Fernglases dort von entscheidendem Vorteil, wo die Gefahr besteht, daß das Glas ins Wasser fällt, so insbesondere beim Wassersport, wie Segeln oder Paddeln u. dgl. Fallen bekannte Glä- ser versehentlich ins Wasser, gehen sie sofort unter und sind für den Besitzer im allgemeinen unwiederbringlich verloren. Ein erfindungsgemäß ausgebildetes Glas schwimmt hingegen und kann ohne weiteres wie-der aus dem Wasser gefischt werden. Durch einfachste Mittel, nämlich die Wahl eines geeigneten Überzugstoffes, können auf diese Weise oft empfindliche Verluste vermieden werden.According to the invention it was surprisingly found that binoculars can be made floatable if, instead of the known leather cover, protective covers made of a material with a suitably low specific weight are used. In this way it is possible to reduce the weight of the glass, based on its total volume, at least so far that the glass floats in the water. While it is generally useful to make binoculars as light as possible, as this largely avoids fatigue when using the glass with your free hand, the buoyancy of the binoculars is a decisive advantage where there is a risk of the glass falling into the water falls, especially during water sports such as sailing or paddling and the like. If known glasses accidentally fall into the water, they are immediately lost and are generally irretrievably lost for the owner. A glass designed according to the invention, on the other hand, floats and can easily be fished out of the water again. By the simplest means, namely the choice of a suitable covering material, sensitive losses can often be avoided in this way.

Als besonders geeignet erwiesen sich Korküberzüge. Korktafeln sind im Handel in verschiedenen Dicken erhältlich und können ohne weiteres als überzüge verarbeitet werden. In einem praktischen Anwendungsbeispiel wurde ermittelt, daß das Gesamtgewicht eines Fernglases mit Lederilberzug von 455 g durch den Austausch des Lederüberzuges gegen einen Korküberzug von 2 mm Stärke um 60 g bei Eintauchen des Glases in Wasser gesenkt wurde, ein Betrag, der ausreichte, das Glas schwimmfähig zu machen. Neben dem geringen Gewicht haben Korküberzüge, verglichen mit den üblichen Lederüberzügen, den weiteren Vorteil, daß der Schlagschutz des Glases wegen,#der günstigen Polstereigenschaften des Korkes erheblich verbessert ist.Cork covers have proven to be particularly suitable. Cork boards are commercially available in various thicknesses and can easily be processed as coatings. In a practical application example, it was determined that the total weight of a pair of binoculars with a leather silver cover of 455 g was reduced by 60 g when the glass was immersed in water by replacing the leather cover with a 2 mm thick cork cover, an amount that was sufficient to make the glass floatable close. In addition to their low weight, cork covers have the further advantage compared with the usual leather covers that the protection against impact of the glass is considerably improved because of the favorable cushioning properties of the cork.

Die Zeichnung zeigt ein Ausführungsbeispiel eines erfindungsgemäß ausgebildeten Fernglases, dessen Körper 1 und Objektivstützen 2, 3 Schutzüberzüge 4, 5 bzw. 6 aus einer Korkschicht tragen.The drawing shows an embodiment of binoculars designed according to the invention, the body 1 and lens supports 2, 3 of which have protective coatings 4, 5 and 6 , respectively, made of a layer of cork.
