  Photographische Kamera

 <Desc/Clms Page number 2> 

 
Erfindung betrifftdie Kamerarückwand 8 mit dem Kameragehäuse 1 in nicht dargestellter Weise verriegelt und in der andern Endstellung ist die Verriegelung gelöst und die Kamerarückwand 8 abnehmbar. 



   Wird der in Fig. 1 dargestellte Drehknopf 9 im Uhrzeigersinn gedreht, so wird der zweiarmige Hebel 13 durch die Kurve 10 gleichfalls im Uhrzeigersinn bewegt und hebt dabei die Transportrollenachse 3 entgegen der Kraft der Druckfeder 6. Dadurch wird der Stift 5 aus einer der sich kreuzenden Nuten 4 herausgehoben und somit die Kupplung zwischen der Filmtransportrolle 2 und der Transportrollenachse 3 zum Zweck der Filmrückspulung gelöst. Sobald diese Stellung nach einer Drehung um 900 erreicht ist, rastet der Hebel 13 fühlbar in die Vertiefung 11 ein. Erst bei einer weiteren Drehung über die Raste 11 hinaus wird der Verschluss der Kamerarückwand geöffnet. 



   Die Fig. 2 und 3 zeigen zwei Ausführungen, bei denen der gleiche Effekt unter Fortlassung des zweiarmigen Hebels erreicht wird. In diesen Figuren sind die Teile mit gleichen Funktionen wie in Fig. l, auch mit den gleichen Bezugsziffern, bezeichnet. In Fig. 2 ist der ebenfalls gleichzeitig zur Verriegelung der Kamerarückwand 8 dienende Drehknopf 9'mit einer Kurve 101 und einer Vertiefung 11' versehen, auf der die ballige Stirnfläche der Transportrollenachse 3 direkt beim Verdrehen des Drehknopfes 91 entlanggleitet, gehoben wird und gleichfalls nach einer Drehung um 900 in die Vertiefung 11'einrastet. 



   Die gleiche Wirkung wird auch bei   einer Ausführung   nach Fig. 3 erzielt, wo an Stelle einer Drehverriegelung eine nicht in allen Einzelheiten dargestellte Schieberverriegelung 14 angewendet wird. Mit

    PATENTANSPRÜCHE :    
1. Photographische Kamera mit einer Verriegelungsvorrichtung des die Filmeinlegeöffnung oder - klappe abdeckenden Kameragehäuseteiles, dadurch gekennzeichnet, dass ein Verriegelungsdrehknopf (9) oder Schieber (14) mit einem ansteigenden und abfallenden Kurvenstück (10,   10 "   10") samt einer mittleren zwischen der   Offen- und Schliessstellung   liegenden Rast (11) ausgestattet ist. mit welchem das Ende der Filmtransportrollenachse (3) mittel-oder unmittelbar zusammenarbeitet, wobei die Raststellung (11) zum Anheben der Achse (3) und somit zur Entkupplung der Filmtransportrolle (2) von der Achse (3) zwecks Filmrückspulung dient.

The invention relates to the camera back wall 8 locked to the camera housing 1 in a manner not shown and in the other end position the lock is released and the camera back wall 8 can be removed.



   If the rotary knob 9 shown in Fig. 1 is turned clockwise, the two-armed lever 13 is also moved clockwise by the cam 10 and lifts the transport roller axle 3 against the force of the compression spring 6. This turns the pin 5 from one of the intersecting ones Grooves 4 lifted out and thus the coupling between the film transport roller 2 and the transport roller axis 3 for the purpose of film rewinding is released. As soon as this position has been reached after a rotation of 900, the lever 13 can be felt to engage in the recess 11. Only with a further rotation beyond the catch 11 is the closure of the camera rear wall opened.



   FIGS. 2 and 3 show two designs in which the same effect is achieved with the omission of the two-armed lever. In these figures, the parts with the same functions as in FIG. 1 are denoted by the same reference numerals. In Fig. 2, the rotary knob 9 ', which is also used to lock the rear wall 8 of the camera, is provided with a curve 101 and a recess 11', on which the spherical end face of the transport roller axle 3 slides along directly when the rotary knob 91 is turned, and also after a Turning by 900 engages in the recess 11 '.



   The same effect is also achieved in an embodiment according to FIG. 3, where a slide lock 14, not shown in detail, is used instead of a rotary lock. With
 EMI2.1
 1 and 2, as soon as the transport roller axis 3 is locked into the recess 11 ".



    PATENT CLAIMS:
1. Photographic camera with a locking device of the film insertion opening or flap covering the camera housing part, characterized in that a locking knob (9) or slide (14) with a rising and falling curve piece (10, 10 "10") together with a middle between the open - and closed position lying latch (11) is equipped. with which the end of the film transport roller axis (3) cooperates directly or indirectly, the latching position (11) being used to raise the axis (3) and thus to decouple the film transport roller (2) from the axis (3) for the purpose of film rewinding.
