Description
Die Erfindung betrifft ein Mastfernrohr, welches auf einer Plattform, z. B. auf einem Schiff, zu errichten ist, wobei bezweckt wird, das Fernrohr sowohl über der Plattform, d. h. vom Schiffsdeck aus oder vom Schiffsinnern — unterhalb der Plattform — für die Benutzung zugänglich zu machen. Die Erfindung besteht darin, daß zwei wechselweise benutzbare Okularteile vorgesehen sind,The invention relates to a mast telescope which is mounted on a platform, e.g. B. on one Ship, is to be erected, the aim of which is to position the telescope both above the platform, i.e. H. from the ship deck or from inside the ship - below the platform - for use to make accessible. The invention consists in that two alternately usable eyepiece parts are provided,
ίο von denen der eine unterhalb der Plattform sitzt, während der oberhalb der Plättform befindliche Okularteil in die optische Achse und aus dieser heraus bewegbar ist.ίο of which the one below the platform sits, while the ocular part located above the platform in the optical axis and can be moved out of this.
Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung. Der in beliebieger Weise ausgeführte Mast oder das Traggerüst α kann verlängerbar sein und beim Nichtgebrauch eingezogen werden. Oben ist der Objektivteil b des Fernrohrs befestigt. Passend zu diesem sind der Erfindung gemäß zwei Okularteile vorgesehen. Der eine Okularteil c ist unter der Plattform im Schiffsraum befestigt und der andere Teil c1 außerhalb angebracht. Letzterer kann wagerecht gedreht werden und luht dieserhalb schwenkbar in Lagern d, derart, daß man den Okularteil in die optische Achse führen oder, wenn nicht benutzt, in seiner punktiert angedeuteten Ruhelage beläßt.' Das im Schiffsinnern befindliche Okular c wird durch eine Glasplatte e o. dgl. vom Äußeren abgeschieden und gegen das Eindringen von Wasser geschützt. Für das auf Deck vorgesehene Okular läßt sich eine geeignete Schutzhülle benutzen, die dasselbe, wenn erforderlich, vollständig umgibt.The drawing shows an embodiment of the invention. The mast or the supporting structure α can be extended and retracted when not in use. The objective part b of the telescope is attached at the top. According to the invention, two eyepiece parts are provided to match this. One eyepiece part c is attached under the platform in the hold and the other part c 1 is attached outside. The latter can be rotated horizontally and is therefore pivotable in bearings d in such a way that the eyepiece part is guided into the optical axis or, if not used, left in its rest position indicated by dotted lines. ' The eyepiece c located inside the ship is separated from the outside by a glass plate e or the like and protected against the ingress of water. A suitable protective cover can be used for the eyepiece provided on deck, which, if necessary, completely surrounds it.
