KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Vorliegende Erfindung betrifft eine Einstellvorrichtung an photographischen Cameras, bei denen das Vordertheil mit dem Hintertheile durch Nürnberger Scheeren verbunden ist. Bei den bekannten Cameras dieser Art war sowohl das rechte wie das linke Scheerenpaar durch Schraubenspindeln verstellbar, so dafs auch eine Neigung des Objectivbrettes gegen den Hinterrahmen herbeizuführen war. Die vorliegende Erfindung bezweckt nun, das Objeetivbrett bei jeder Einstellung parallel zu dem Hinterrahmen zu halten. Zu diesem Behufe sind die an den gegenüberliegenden Seiten der Camera befindlichen Scheerenhebel durch eine Lenkervorrichtung mit einander verbunden.The present invention relates to an adjustment device on photographic cameras which the front part is connected to the rear part by Nuremberg scissors. at The known cameras of this type had both the right and the left pair of scissors through Adjustable screw spindles, so that an inclination of the objective board against the Rear frame was to be brought about. The present invention now aims at the lens board keep parallel to the rear frame at each adjustment. To this end, those on opposite sides of the Camera located scissor levers connected to each other by a steering device.
In der Zeichnung ist die am Apparat angebrachte Lenkervorrichtung in Fig. 1 und 2 in zwei verschiedenen Vertikalansichten, in Fig. 3 in einer Draufsicht und in Fig. 4 in einem Vertikalschnitt dargestellt.In the drawing, the handlebar device attached to the apparatus is shown in FIGS. 1 and 2 in two different vertical views, in Fig. 3 in a plan view and in Fig. 4 in a vertical section shown.
Der durch Balgen c mit dem Hinterrahmen a verbundene Objectivrahmen b ist mittels zweier auf gegenüberliegenden Seiten an beiden Rahmen angebrachter Scheerenhebel d gegen den Hinterrahmen in bekannter Weise verstellbar, indem jeder einzelne Hebel einen festen Fufspunkt e bezw. k und einen in dem betreffenden Cameratheil in Schlitzen g bezw. gl verschiebbaren Fufspunkt / bezw. f1 hat. Das Wesen der Erfindung beruht nun darin, dafs zwei der verschiebbaren Drehpunkte zwangläufig mit einander dadurch verbunden sind, dafs zwei auf einer Achse k befestigte Hebel i von gleicher Länge und gleicher Schräglage mittels Gelenkstangen h an jene verschiebbaren Enden/der Scheerenhebel d angreifen. Erfolgt die Verschiebung eines der vier verschiebbaren Scheerenhebelenden, so werden dadurch die anderen drei genau gleich weit verschoben, wodurch bei jeder Einstellung eine Parallelstellung von Objectivbrett nnd Hinterrahmen gesichert ist.The c by bellows with a rear frame connected by means of two Objectivrahmen b is attached on opposite sides of the two frame Scheer lever d adjustable against the rear frame in known manner by each individual lever BEZW a fixed Fufspunkt e. k and one in the relevant camera part in slots g respectively. gl movable foot point / respectively. f has 1 . The essence of the invention is based on the fact that two of the displaceable pivot points are inevitably connected to one another in that two levers i of the same length and inclined position attached to an axis k act on those displaceable ends / the scissor lever d by means of articulated rods h . If one of the four displaceable scissor lever ends is displaced, the other three are displaced by exactly the same amount, whereby a parallel position of the lens board and the rear frame is ensured with every setting.
Claims (1)
Parallelführung für Vorder- und Hinterrahmen von photographischen Cameras, bei denen diese Theile durch Scheerenhebel mit einander verbunden sind, die je einen festen und einen gleitenden Fufspunkt haben, dadurch gekennzeichnet, dafs zwei an demselben Cameratheil gegenüberliegende gleitende Fufspunkte (f) mittels einer die Camera durchsetzenden Lenkervorrichtung (h i) zwangläufig mit einander verbunden sind.Patent-An saying:
Parallel guidance for the front and rear frames of photographic cameras, in which these parts are connected to one another by scissor levers, each having a fixed and a sliding foot point, characterized in that two sliding foot points (f) opposite one another on the same camera part penetrate the camera by means of one Handlebar device (hi) are inevitably connected to each other.
