Description
Die bekannte Schwierigkeit des Sicherns focussierbarer Instrumente vor der Möglichkeit des Eindringens von Feuchtigkeit in das Innere hat in vielen Fällen zur Verwerfung der sogenannten »Mitteltriebverstellung« in binokularen Instrumenten und zur Einführung der bekannten Einzelfocussiereinricbtung geführt, die in der Tat für den gewollten Zweck eine viel höhere Sicherheit gewährt.The familiar difficulty of securing focusable instruments from the possibility the penetration of moisture into the interior has in many cases resulted in warping the so-called "central drive adjustment" in binocular instruments and for introduction the well-known Einzelelfocussiereinricbtung, which in fact for the intended purpose granted a much higher level of security.
ίο Indessen auch hierbei hat die Steigerung der Ansprüche nicht stehen bleiben können, nachdem sich gezeigt hat, daß auch in den vorgenannten Einzelfocussiereinrichtungen bei Einwirkung einer zur umgebenden Luft in starker Temperaturdifferenz stehenden Feuchtigkeit, diese infolge einer gewissen Saugwirkung, die beim Focussieren noch erhöht wird, durch die Gewindegänge des verstellbaren Teiles (Okulars) hindurch den Weg ins Instrumentinnere finden kann, was besonders beimίο Meanwhile, here too, the increase of the claims cannot stand after it has been shown that also in the afore-mentioned individual focusing devices with the action of a to the surrounding air in strong temperature difference, this due to a certain suction effect, which is increased when focusing, through the threads of the adjustable part (eyepiece) through the way into the interior of the instrument can find what especially at

Vorliegende Erfindung soll diesen Fehler in vollkommener Weise durch Schaffung eines Hohlraumes g beseitigen, der sich zwischen den gegeneinander bewegenden Einstellorganen befindet und mit Dichtungsmaterial ausgefülltThe present invention is intended to fully address this flaw by providing a Eliminate cavity g between the adjusting members moving against one another and filled with sealing material
-- wird, wie Fett, Harz, Wachs ο. dgl., das in mittlerer Temperatur streichbar und in Wasser unlöslich ist. Die mechanische Anordnung ist eine derartige, daß der Hohlraum nach außen hin völlig abgeschlossen ist. Eine solche Möglichkeit ist in der Zeichnung dargestellt und wird erreicht z. B. durch Einführung ' der federnden Hülse f. - Dieselbe wird durch Verschrauben von Teilungsring I und Rändelkopf r mit diesem ganzen der Focussierung dienenden Teile, z. B. dem Okular, fest verbunden und legt sich an die Wandung der Okularhülse h an,- hierdurch schon den ersten Schutz gegen Eindringen von Feuchtgkeit bietend. Den Hauptwert jedoch erhält die neue Einrichtung dadurch, daß sie den nach außen abgeschlossenen, mit Dichtungsmitteln ausgefüllten Hohlraum g schafft, der das Vordringen von Feuchtigkeit z. B. bis zu den Gewindegängen ausschließen soll.- will, such as fat, resin, wax ο. Like. That is spreadable in medium temperature and insoluble in water. The mechanical arrangement is such that the cavity is completely closed off from the outside. Such a possibility is shown in the drawing and is achieved z. B. by introducing 'of the resilient sleeve f -. The same is r by screwing of division ring I and knurled head with this whole the focussing serving parts such. B. the eyepiece, firmly connected and rests against the wall of the eyepiece sleeve h , - thereby offering the first protection against the ingress of moisture. However, the main value of the new device is that it creates the closed to the outside, filled with sealant cavity g, which prevents the penetration of moisture z. B. should exclude up to the threads.
