Die Erfindung betrifft eine photographische Kamera mit einem mehrere Federn enthaltenden Federwerk, bei welcher z. B. der Filmtransport durch die aufgespeicherte Federkraft bewirkt wird.The invention relates to a photographic camera having a plurality of springs Spring mechanism, in which z. B. the film transport through the stored spring force is effected.

Hauptsächlich dann, wenn eine Kleinbildkamera mit einem automatischen Filmtransport versehen sein soll, ist man bemüht, die äußere Form der Kamera so klein als mög-Hch zu halten. Trotzdem muß aber die Feder, die mehrere Vorgänge, wie z. B. Filmtransport, Verschlußspannen, Bildzählen usw., zu bewirken hat, genügend Kraft hergeben können, und sie soll auch, weil sie leicht dem Bruch unterworfen ist, auf einfachste Art und Weise auswechselbar sein.Mainly when a 35mm camera with an automatic film transport should be provided, one tries to keep the external shape of the camera as small as possible to keep. Nevertheless, the spring, which has several processes, such. B. film transport, Shutter cocking, picture counting, etc., has to bring about enough force can, and it should also, because it is easily subject to breakage, in the simplest way and Way to be interchangeable.

Die photographische Kamera mit dem Federwerk gemäß der Erfindung ist nun dadurch gekennzeichnet, daß das Federhaus von außen her derart in eine Kamerawandung eingesetzt ist, daß ein Teil des Federhauses nach außen aus dem Kameragehäuse herausragt und daß der herausragende Teil des Federhauses einen größeren Innendurchmesser als der innenliegende Teil hat und eine Feder größeren Durchmessers als der innenliegende Teil aufnimmt. Durch diese neue Ausführungsform wird erreicht, daß durch die Verwendung eines Federwerkes und der dazu nötigen Einrichtung zur Regulierung des sanften und ruckfreien Ablaufens beim Filmtransport keine Vergrößerung des Kamerakörpers nötig wird. Ferner ist die Feder leicht zugänglich, ohne daß die eigentliche Kamera auch nur teilweise zerlegt werden müßte, wobei trotz des kleinen beanspruchten Raumes eine bedeutende Kraft erzielt wird.The photographic camera with the spring mechanism according to the invention is now through characterized in that the barrel is used from the outside in such a way in a camera wall is that part of the barrel protrudes outwardly from the camera body and that the protruding part of the barrel has a larger inner diameter than the inner part and a spring of larger diameter than the inner part Part takes up. With this new embodiment it is achieved that through the use of a spring mechanism and the to it necessary device to regulate the smooth and jerk-free running during film transport no enlargement of the camera body is necessary. Furthermore, the spring is easily accessible without the actual Camera would only have to be partially disassembled, although claimed despite the small size A significant force is achieved.

In der Zeichnung ist der Erfindungsgegenstand in einem Ausführungsbeispiel dargestellt. Es zeigenIn the drawing, the subject matter of the invention is shown in an exemplary embodiment. Show it

Fig. 2 eine Seitenansicht zu Fig. 1, in der das Kameragehäuse ebenfalls geschnitten ist.FIG. 2 is a side view of FIG. 1, in which the camera housing is also cut.

Ein den Filmtransport beeinflussendes Regelwerk, bestehend aus den zwischen zwei Platinen 1 und 2 gelagerten Laufrädchen 3 bis 6, ist unter der Seitenwand 7 der Kamera so angeordnet, daß es in dem von der Bildbühne 8 und Seitenwand 7 gebildeten Winkel über dem Bildfenster 9 liegt. Durch eine Öffnung 10 in der Kameraseiten wand kann nun ein Federhaus 11 von außen eingesetzt werden, das in Eingriff mit dem Trieb des Rades 6 und einem Zahnrad 13 auf der Filmtransportrolle 14 steht. Der Durchmesser des Federhauses ist nun durch diese Zahneingriffe im Innern der Kamera begrenzt. Da das Federhaus jedoch teilweise außerhalb des Kamerakörpers liegt, so ist die Möglichkeit gegeben, seinen Umfang hier zu vergrößern.A set of rules influencing film transport, consisting of the between two Circuit boards 1 and 2 mounted wheels 3 to 6, is under the side wall 7 of the camera arranged so that it is in the angle formed by the picture stage 8 and side wall 7 is above the image window 9. Through an opening 10 in the camera side wall can now a barrel 11 can be used from the outside, which engages with the drive of the Wheel 6 and a gear 13 on the film transport roller 14 stands. The diameter of the barrel is now due to this gear mesh limited inside the camera. However, since the barrel is partially outside the camera body, there is a possibility given to enlarge its scope here.

Claims

In the spring house two springs 15 and 16 are then housed, of which the outer has a larger diameter than the inner. Not only that the use of a larger, i.e. stronger spring in the upper Ί & Γ of the barrel is possible, but the * a | f | The force acting on the intervention is further increased by the fact that the diameter of the outer spring is as large or larger than the gear rim of the barrel, so that an increased force is exerted on the wheel 13 due to the greater leverage On the barrel 11, the hood 17 is placed over the barrel from the outside and fastened to the camera wall, for example, by screws 18, -19 aI1 and height must have, in order to be able to grasp it comfortably when pulling up the spring, now covers the locking mechanism attached to the hood 17. Due to the described arrangement and the laying of the spring partly inside the camera, partly under the elevator element, the other parts, For example, the width of the film, the height of the cassettes, the required dimensions of the camera remain unchanged and just as small as with a camera without a spring mechanism A camera without a spring mechanism would not use enough space. Then, after removing only two parts, 20 and 17, the spring can be replaced, and finally a significant force is achieved by using the stronger and larger spring in the part of the barrel outside the camera body. The rules 1 to 6 can of course also any other device, for. B. be an anchor escapement or an air or liquid brake instead of the running wheels 3 to 6 .i1 · ".

1. Photographic camera with a spring mechanism containing several springs, characterized in that the barrel from the outside in such a way in a camera wall is used that a part of the barrel protrudes outwardly from the camera housing and that the outstanding Part of the barrel has a larger inner diameter than the inner part and a spring of larger diameter than the inside part picks up.

2. Photographic camera according to claim i, characterized in that the Radius of the drive ring gear attached to the barrel is smaller than the distance of the point of application of the The spring lying in the protruding part of the barrel on the inner wall of this part of the barrel axis.

3. Photographic camera according to claim ι or 2, characterized in that that the set of rules influencing the process of the spring mechanism in that of the front and side walls of the camera as well The space bounded by the picture stage is housed and that the barrel inserted from the outside is attached to this space enclosing walls is stored.

4. Photographic camera according to claim 1, 2 or 3, characterized in that that the barrel or the hood serving as a counter bearing is completely or partially covered by the winding handle.
