Description

Der Gegenstand der Erfindung betrifft eine photographische Spreizenkamera, deren Objektiv zwecks Scharfeinstellung auf ein aufzunehmendes Objekt in an sich bekannter Weise mit einem Basisentfernungsmesser, vorzugsweise in Verbindung mit einem Drehoder Schwingkeilpaar, gekuppelt ist. Die Bewegung des Dreh- oder Schwingkeilpaares, welche erforderlich ist, um den MeßstrahlThe subject matter of the invention relates to a photographic spread camera, the lens of which for the purpose of focusing on an object to be recorded in a manner known per se with a base range finder, preferably in connection with a pair of rotating or swinging wedges. The movement of the rotating or swinging wedge pair, which is required to move the measuring beam

ίο des Entfernungsmessers abzulenken, wird neuerwngsgemäß von der an sich bekannten Verstellung der Spreizen, welche mittels ■ geeigneter Organe mit dem Dreh- oder Schwingkeilpaar gekuppelt sind, abgeleitet.ίο the rangefinder will deflect according to the presently known adjustment of the spreaders, which by means of ■ suitable Organs are coupled to the rotating or rocking wedge pair, derived.

In den Abb. 1 und 2 der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt. Durch Verstellung des mit einer Entfernungsskala versehenen Einstellknopfes 1 der Spreizenkamera 2 wird eine Gewindespindel 3 bewegt. Die Übertragung der Bewegung kann direkt oder auch unter Zwischenschaltung von Zahnrädern 4, 5 und 6 erfolgen. Die Spindel 3 ist in ihrer _ Lagerung gegen axiale Verschiebung gesichert.In Figs. 1 and 2 of the drawing, the invention is in one embodiment shown. By adjusting the setting knob 1, which is provided with a distance scale the spreading camera 2 a threaded spindle 3 is moved. The transmission of motion can be done directly or with the interposition of gears 4, 5 and 6. The spindle 3 is in its _ storage secured against axial displacement.

Auf der Spindel befindet sich eine Gewindemutter 7, welche mit einer Spreize 8 der Kamera 2 gelenkig verbunden ist. Versetzt man die Spindel 3 in Umdrehungen, so wird das Mutterstück 7 auf und ab bewegt, wobei die Spreize 8 des Objektivträgers 9 längs des Laufbodens verschiebt und eine scharfe Abbildung des aufzunehmenden Objektes erzielt werden kann. Mit dem Zahnrad 6 der Spindel 3 ist durch Einschaltung eines Zahnrades 10/ welches auf seiner Achse ein Kegelrad 11 trägt, das Dreh- oder Schwingkeilpaar 12 des Basisentfernungsmessers 13 gekuppelt. Das Keilpaar erhält eine gegenläufige Bewegung, um eine Ablenkung des Meßstrahles zu erzielen. Um die Kamera zu schließen, werden die Spreizen 14, 15 aus Rasten 16, 17, welche sich in schwenkbar angebrachten Hebeln 18„ befinden, ausgerastet. Die Spreizen 14,15 gleiten dann in ihrer jeweiligen Nut 20,21 der Kamera 2 entlang.On the spindle there is a threaded nut 7, which with a spreader 8 of the camera 2 is articulated. If you set the spindle 3 in revolutions, this will be Nut 7 moved up and down, the spreader 8 of the lens carrier 9 along the Moves walking floor and achieved a sharp image of the object to be recorded can be. With the gear 6 of the spindle 3 is by switching on a gear 10 / which has a bevel gear 11 on its axis carries, the rotating or swinging wedge pair 12 of the base rangefinder 13 coupled. That The pair of wedges is moved in opposite directions in order to deflect the measuring beam. To close the camera, the spreaders 14, 15 are made of catches 16, 17, which pivoted levers 18 " located, disengaged. The spreaders 14, 15 then slide in their respective groove 20, 21 the camera 2 along.
