Description

wonnenblende für optische Geräte.lens hood for optical devices.

Gegenstand der Erfindung ist eine Sonnenblende für optische Geräte wie Kameras, Ferngläser, optische Entfernungsmesser usw.The invention relates to a sun visor for optical devices such as cameras, binoculars, optical rangefinders, etc.

deren Aufgabe es ist, den seitlichen Einfall von Sonnen- oder Scheinwerferlicht in das Objektiv zu verhüten.whose task it is to block the incidence of sunlight or headlights from the side into the lens to prevent.

Die bisher bekannten Sonnenblenden sind entweder tubusförmige Aufsatzgeräte oder äompendien, die dem Objektiv aufgesetzt, bezw. vorgeschaltet wurden. Ihr Nachteil ist, daß sie sehr voluminös, relativ schwer und mitunter bei der Arbeit hinderlich sind.The previously known sun visors are either tubular attachments or Äompendien that placed on the lens, respectively. upstream. Your disadvantage is that they are very bulky, relatively heavy and sometimes a hindrance to work are.

Die erfindungsgemäße Sonnenblende behebt diese Nachteile dadurch, daß sie aus einem Lamellen-Gitterraster besteht, der direkt auf das Objektiv aufgesetzt wird. Dadurch wird das Objektiv in mehrere einzelne Sektoren aufgeteilt, wobei dann jeweils der umgrenzende Lamellen-Gitterraster den Sonnenschutz für den Objektiv-Sektor übernimmt.The sun visor according to the invention overcomes these disadvantages by that it consists of a lamellar grid that is placed directly on the lens will. This divides the lens into several individual sectors, whereby then In each case, the surrounding louvre grid provides the sun protection for the lens sector takes over.

Auf diese Weise braucht die Sonnenblende selbst für große Objektiv-Durchmesser nicht höher als vielleicht 1 cm zu sein.In this way, the sun visor needs even for large lens diameters not to be higher than maybe 1 cm.

Ein weiterer Vorteil ist der, daß die Objektive herstellungsseitig bereits mit Sonnenblenden ausgerüstet werden können.Another advantage is that the lenses are manufactured on the manufacturing side can already be equipped with sun visors.
