Description

Vorderdeckel- bzw. Laufbodenzuhaltung an fotografischen Kameras Die Erfindung betrifft eine Kameravorderdeckel-bzw. Laufbodenzuhaltung. Solche Einrichtungen sind an sich bekannt ulid in verschiedentlichster Weise zur Anwendung gekommen.Front cover or barrel locking device on photographic cameras The invention relates to a camera front cover or. Walking floor guard. Such facilities are known to have been used in the most varied of ways.

Gegenstand der Erfindung ist ein die Vorderdeckel- bzw. Laufbodenzuhaltung bildender Teil (Hebel o. dgl.), der unter Wirkung einer einzigen Feder steht, die durch ihfe besondere Formgebung nicht nur das Festhalten des `'orderdeckels, sondern auch das Rückführen des genannten Hebels in seine Anfangs- bzw. Nichtgebrauchslage veranlaßt. Dies geschieht entgegen der Wirkung des diese einzige Feder betätigenden Teiles (Knopf o. dgl.). Der die Zuhaltung bildende Teil befindet sich mit seinen Betätigungsmitteln an der Innenseite des Hohlraumes der Kamera, in dem auch der Entfernungsmesser, Sucher, Belichtungsmesser usw. untergebracht sind, und zwar an der Wand, die gleichgerichtet zum Vorderdeckel der Kamera verläuft bzw. bei geschlossener Kamera als Verlängerung hierzu anzusehen ist.The subject of the invention is a front cover or barrel floor tumbler forming part (lever or the like), which is under the action of a single spring thanks to their special shape, not only the holding of the '' order lid, but also the return of said lever to its initial or non-use position caused. This happens against the action of this single spring actuating Part (button or the like). The part that forms the tumbler is located with its Actuating means on the inside of the cavity of the camera, in which the Range finder, viewfinder, exposure meter, etc. are housed, namely on the wall that runs in the same direction as the front cover of the camera or when it is closed The camera is to be regarded as an extension of this.

Eine Ausführungsforen des Erfindungsgegenstandes ist in einem Beispiel zeichnerisch wiedergegeben, und zwar zeigt Ahb. i eine Auslösebetätigung mittels Schieber, Abb. 2 eine Seitenansicht dazu, Abb. 3 eine Auslösebetätigung mittels Knopf. Im Hohlraum i der Kamera, der den Entfernungsinesser, Belichtungsmesser, Sucher usw. aufnimmt, ist in der Wand 2, die zum Vorderdeckel gleichgerichtet verläuft, das Lager 3 für den Zuhalteteil 4 befestigt. Durch Verschieben des Auslöseknopfes 5 am zweifach abgewinkelten Schieber 6 gleitet die Fläche 6a des Schiebers entlang der Fläche 4a des Zuhalteteils. Dabei gibt der zum Zuhalteteil abgewinkelte Zuhalteriegel 4b mit seiner Nase 4c den Vorderdeckel bzw. Laufboden 7 frei. Beim Loslassen des Knopfes 5 schiebt die Schraubenfeder 8, deren Drehachse das Lager 3 bildet und die mit dem Schenkel 8a auf dem Zuhalteriegel4b aufliegt. mit dein Schenkel 8b den Schieber 6 in seine Ausgangslage zurück. Beim Schließen des Laufbodens bzw. Kaineravorderdeckels 7 gleitet die Kante 7° desselben entlang der Schrägfläche 4d des Zuhalteriegels 4b, bis die Nase 4c in der Aussparung am Laufboden bzw. Kameravorderdeckel 7 einrastet.An embodiment forum of the subject invention is in an example graphically reproduced, namely shows Ahb. i a trigger actuation by means of Slide, Fig. 2 a side view of this, Fig. 3 a trigger actuation by means of Stud. In the cavity i of the camera, which measures the distance meter, light meter, Viewfinder, etc., is in the wall 2, which runs in the same direction as the front cover, the bearing 3 for the locking part 4 is attached. By moving the release button 5 on the double-angled slide 6, the surface 6a of the slide slides along the surface 4a of the locking part. The locking latch, angled towards the locking part, is there 4b with its nose 4c exposes the front cover or running floor 7. When you let go of the Button 5 pushes the coil spring 8, whose axis of rotation is the bearing 3 forms and which rests with the leg 8a on the tumbler latch 4b. with your Leg 8b returns the slide 6 to its original position. When closing the walking floor or Kaineravfrontdeckels 7, the edge 7 ° of the same slides along the inclined surface 4d of the tumbler 4b until the nose 4c is in the recess on the floor or the front cover of the camera 7 clicks into place.

In Abb.3 liegt der Schenkel 8b der Schraubenfeder 8 an der Innenfläche der Wand io des Hohlraumes i an. Die abgewinkelte Fläche 411 des Hebels4 wird durch die Schraubenfeder 8 gegen die Kegelfläche ca des Auslöseknopfes 9 gedrückt. Der Knopf 9 ist gegen unbeabsichtigtes Betätigen zweckmäßigerweise vertieft angebracht.In Fig.3 the leg 8b of the helical spring 8 rests against the inner surface of the wall io of the cavity i. The angled surface 411 of the lever 4 is pressed by the helical spring 8 against the conical surface ca of the release button 9. The button 9 is expediently recessed against unintentional actuation.

Claims

PATENT CLAIMS: i. Front cover or running floor tumbler on photographic cameras, characterized in that a part (lever) forming the tumbler is under the action of a spring which not only keeps the tumbler but also the return of the part (button, etc.) that actuates the lever against the action of this spring . Like.) in its initial position.
