Description

(H9I5I5 VI1 (H 9 I 5 I 5 VI 1

Die Erfindung betrifft eine Lichtschutzvorrichtung für Objektive, Gemäß der Erfindung ist sie mittels eines Kugelgelenkes an dem Objektiv befestigt. Dadurch kann ihr jede beliebige Neigung zur optischen Achse gegeben werden.The invention relates to a light protection device for lenses, according to the invention it is attached to the lens by means of a ball joint. This means you can each any inclination to the optical axis can be given.

In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt, und zwar zeigt:
ίο Abb. ι einen Durchschnitt,In the drawing, the invention is shown in one embodiment, namely shows:
ίο Fig. ι an average,

Abb. 2 eine Außenansicht mit geneigtem Rohransatz,Fig. 2 is an external view with an inclined pipe attachment,

Abb. 3 einen Querschnitt der Gelenkbewegung. Fig. 3 is a cross-section of the joint movement.

Ein Lichtschutzrohr, das teleskopartig zusammenschiebbare Teilen b, c hat, ist mit einem Ring d versehen, der mit seiner gewölbten Oberfläche über einen am Objektiv g der Kamera h angebrachten oder anbringbaren Ringe mit entsprechender Oberfläche greift, so daß der Rohransatz der Lichtschutzvorrichtung zur optischen Achse beliebig verstellt werden kann. Seine Stellung kann durch eine Stellschraube/ gesichert werden.A light protection tube, which has telescopically collapsible parts b, c , is provided with a ring d , which engages with its curved surface over a ring with a corresponding surface attached or attachable to the lens g of the camera h , so that the tube attachment of the light protection device to the optical axis can be adjusted as required. Its position can be secured with an adjusting screw /.

Die Bildgröße kann * in bekannter Weise durch Verlängern oder Verkürzen des Teleskoprohres geändert werden.The image size can * in a known manner by lengthening or shortening the telescopic tube be changed.
