Description

An fotografischen Kameras, insbesondere an Spiegalreflexkamneras, werden zur Kontrolle -des Mattscheibenbildes Lupen verwendet, die entweder am Kameragehäuse oder im Lichtsc'hac'ht .der Kamera klemmbar oder befestigt sind. Diese Arüder Befestigung sichert nicht immer eine bequeme Handhabung der Lupe und insbesondere nicht- immer eine Lupernbetnadhtung sämtlicher B,i-Pdteile.On photographic cameras, especially on mirror reflex cameras, Magnifying glasses are used to control the focusing screen image, either on the camera housing or can be clamped or fastened in the light shaft of the camera. This Arüder fortification does not always ensure comfortable handling of the magnifying glass and, in particular, not always a close fitting of all B, i-Pd parts.

Zur Beseitigung dieses Nachteiles der bekannten Lupen bzw. ihrer Befestigung wird nun der Erfindung gemäß vorgeschhugen, die Halterung der Lupe ganz oder teilweise aus magnetisch wirksamem Material herzustellen oder mit solchem zu verbinden. Besonders zweckmäßig wird -die Lupenfassung mit einem magnetisierten Stiel, Griff, Fuß od. dgl. zu diesem Zweck versehen. Auf diese Weise läßt sich die Lupe selbsthaftend an jeder Stelle des in der Regel aus. Eisen bzw. -StabllSlecsh bestehenden Kameragehäuses oder Lichtschachtes ohne- weiteres befestigen und in jede beliebige Lage verschieben oder verdrehen. Außerdem kann die Lupe im Nichtgebrauch-sf all vollkommen aus dem durch einsfaches Abziehen gänzlich entfernt werden.To eliminate this disadvantage of the known magnifying glasses and their attachment is now proposed according to the invention, the holder of the magnifying glass in whole or in part made of magnetically effective material or to be connected to such. Particularly Appropriate is -the magnifying glass with a magnetized handle, foot or. Like. Provided for this purpose. This way the magnifying glass can be self-adhesive at each point of the usually off. Iron or -StabllSlecsh existing camera housing or light shaft without further ado and move it to any position or twist. In addition, the magnifying glass can be completely removed when not in use can be completely removed by simply pulling them off.

In der Zeichnung ist eine Ausführungsform der erfindungsgemäßen Lupe beispielsweise dargestellt. Die Fassung der Lupe i ist mit einem Stiel 2 versehen, der einen aus magnetischem bzw. !dauermagnetisiertem Material bestehenden Fuß 3 besitzt, dessen Auf liagefläehe infolge der Magnetisi:er.ung an jeder Stelle der Wandung 4 des Lichtschachtes haftet, sobald die Lupe bzw. der Lupenfttß 3 auf die Wandung aufgesetzt wird. -Ebenso leicht ist eine Verschiebung oder Drehung der Lupe auf der Schachtwandung möglich.In the drawing is an embodiment of the magnifying glass according to the invention for example shown. The frame of the magnifying glass i is provided with a handle 2, the one made of magnetic or permanently magnetized material foot 3 whose contact surface is due to magnetization at every point of the Wall 4 of the light shaft sticks as soon as the magnifying glass or the Lupenfttß 3 on the Wall is placed. Moving or rotating the magnifying glass is just as easy possible on the shaft wall.
