Description

Die bisher bekanntgewordenen Fernrohrbrillen bestanden aus zwei Fernrohrhälften und einem Trägergestell, ähnlich einer Brillenfassung. Dieses Trägergestell war entweder ganz aus Metall und verdeckte vollkommen die freie Sicht nach den Seiten, oder es bestand aus einer normalen Brillenfassung mit eingesetzten Plangläsern, die zur Aufnahme der beiden Fernrohrhälften dienten. Der Nachteil des letzteren bestand darin, daß das normale Brillengestell als Fernrohrträger zu schwach und biegsam ist und damit die Parallelität der beiden Fernrohrachsen nicht gewährleistet ist. Außerdem wirkt sich der Fassungsrand auf die freie Sicht nachteilig aus.The telescope glasses that have become known so far consisted of two telescope halves and a support frame, similar to a spectacle frame. This support frame was either made entirely of metal and completely obscured the unobstructed view to the sides, or it consisted of a normal spectacle frame with flat lenses inserted, which were used to accommodate the two halves of the telescope. The disadvantage of the latter consisted in the fact that the normal spectacle frame as a telescope wearer was too weak and is flexible and thus the parallelism of the two telescope axes is not guaranteed is. In addition, the rim of the frame has a negative effect on the unobstructed view.

Bei der den Gegenstand der Erfindung bildenden Fernrohrbrille ist das Trägergestell für die beiden Fernrehrhälften oder dem in einem einzigen Gehäuse untergebrachten Fernglas aus durchsichtigem Kunststoff hergestellt. Dadurch wird eine freie Durchsicht nach allen Seiten ermöglicht und Störungen eines Fassungsrandes vermieden. Durch das geringe spezifische Gewicht des Kunststoffes kann das Trägergestell ohne Erhöhung des Gewichtes so stark bemessen werden; daß eine Durchbiegung unmöglich ist und damit die Parallelität der Fernrohrachsen gewährleistet bleibt.In the telescopic glasses forming the subject of the invention the support frame for the two halves of the remote control or in a single housing binoculars made of clear plastic. This will enables a clear view on all sides and disrupts a frame edge avoided. Due to the low specific weight of the plastic, the support frame be made so strong without increasing the weight; that deflection is impossible and thus the parallelism of the telescope axes is guaranteed.

In der Zeichnung ist das beispielsweise aus zwei Fernrohrhälften bestehende Fernrohr mit i und 2 und das aus durchsichtigem Kunststoff bestehende Trägergestell mit 3 bezeichnet. Die Fernrohrhälften i und 2 sind entweder fest oder zur Einstellung des Augenabstandes in Langlöchern verschiebbar mit dem Trägergestell 3' verbunden. Die mit 4 und 5 bezeichneten Ohrenbügel sind an dem Trägergestell 3 wie an einer normalen Brillenfassung befestigt.In the drawing this is, for example, consisting of two telescope halves Telescope with i and 2 and the support frame made of transparent plastic labeled 3. The telescope halves i and 2 are either fixed or for adjustment of the interpupillary distance in elongated holes connected to the support frame 3 '. The ear hooks identified by 4 and 5 are on the support frame 3 as on one normal eyeglass frame attached.
