Die vorliegende Erfindung betrifft eine Cassette für photographische Apparate, welche an Stelle der bisher gebräuchlichen Schieber mit Klappen versehen ist, die von aufsen gehandhabt werden können und im Innern der Camera hochklappen, sowie eine zusammenklappbare Camera besonderer Construction mit beweglicher Visirscheibe. The present invention relates to a cassette for photographic apparatus which is in place the previously common slide is provided with flaps that are handled from the outside can and fold up inside the camera, as well as a collapsible camera special construction with movable visor disc.

Auf beiliegender Zeichnung ist in Fig. 1 eine Seitenansicht der Camera, in Fig. 2 ein Längsschnitt derselben dargestellt. Fig. 3 zeigt eine Ansicht von hinten mit fortgenommener Cassette, Fig. 4 einen Schnitt nach Fig. 3; Fig. 5, 6 und 7 stellen die Cassette in verschiedenen Ansichten dar.In the accompanying drawing, FIG. 1 shows a side view of the camera, and FIG. 2 shows a longitudinal section same shown. Fig. 3 shows a rear view with the cassette removed, FIG. 4 shows a section according to FIG. 3; Figures 5, 6 and 7 show the cassette in different views represent.

Die Cassette α, Fig. 5 bis 7, ist hier als Doppelcassefte, d. h. zum Einlegen zweier lichtempfindlichen Platten auf beiden Seiten eingerichtet, gezeichnet. Doch kann für eine einfache Cassette dieselbe Einrichtung getroffen werden. Die Cassette α besteht aus dem Rahmen, in welchen die Platten eingelegt werden können, und zwei Klappen b b, welche die lichtempfindlichen Platten d d bis zur Exponirung bedecken.The cassette α, FIGS. 5 to 7, is drawn here as a double cassette, ie designed for inserting two light-sensitive plates on both sides. However, the same arrangement can be made for a simple cassette. The cassette α consists of the frame in which the plates can be inserted and two flaps bb which cover the light-sensitive plates dd until they are exposed.

Diese Klappen b b sind bei c an den Rahmen im Gelenk drehbar, so dafs sie aufgeklappt werden können, wenn. die Cassette sich in der Camera selbst befindet. Zum Festhalten der Klappen an den Rahmen dienen Häkchen e e aus Draht, welche unten am Rahmen in Hülsen j¹ sich drehen können. Diese Häkchen sind rechtwinklig zu einander gebogen, so dafs sie in der Stellung Fig. 5 beide Klappen b b gleichzeitig festhalten, bei einer Drehung um 45⁰ nach rechts bezw. links eine der Klappen b freigeben, die andere dagegen festhalten. Die Cassette ist ringsum mit Leisten /' versehen, so dafs die lichtempfindlichen Platten gut eingelegt werden können und gegen Verschiebung gesichert sind. Der mittlere Theil ist nach unten bei k^l verlängert, und in die hier entstehende Nuth legen sich die mit Leisten versehenen Klappen b ein und erzielen auf diese Weise einen dichten Abschlufs.These flaps bb are rotatable at c on the frame in the joint, so that they can be opened when. the cassette is in the camera itself. To hold the flaps on the frame, hooks ee made of wire are used, which can rotate in sleeves j ^{1 at the bottom of the frame.} These hooks are bent at right angles to each other, they DAF in the position of Fig. 5, both flaps bb simultaneously hold, BEZW at a rotation of 45 ⁰ to the right. Release one of the flaps b on the left and hold the other against it. The cassette is provided with strips / 'all around so that the light-sensitive plates can be easily inserted and are secured against displacement. The middle part is lengthened downwards at k ¹ , and the flaps b provided with ledges are inserted into the groove formed here, and in this way achieve a tight seal.

Innerhalb der Camera ist der Rahmen f an den Zapfen g¹g¹ am hinteren und oberen Ende der Camera drehbar aufgehängt. Der Rahmen f endigt in Haken g, in welche die Zapfen h der Cassettenklappen b, Fig. 5, eingehängt werden. An einem der Zapfen g^l, der durch die Wand der Camera hindurchreicht; ist aufsen der Handgriff i befestigt, so dafs man durch Drehen am Handgriff i den Rahmen f und gleichzeitig die darin eingehängte Cassettenklappe b nach oben in nahezu horizontale Lage, Fig. 2, bringen und dadurch die lichtempfindliche Platte der Wirkung des Lichts aussetzen kann. Die Cassette wird hierbei an den durch Drähte {¹, Fig. 2 und 3, gebildeten Vorsprüngen fest in ihrer Lage gehalten. Inside the camera, the frame f is rotatably suspended from the pin g ¹ g ¹ at the rear and upper end of the camera. The frame f ends in hooks g, into which the pins h of the cassette flaps b, FIG. 5, are suspended. On one of the pegs g ^l , which extends through the wall of the camera; the handle i is attached to the outside so that by turning the handle i one can bring the frame f and at the same time the cassette flap b suspended in it upwards into an almost horizontal position, Fig. 2, and thereby expose the photosensitive plate to the action of light. The cassette is held firmly in place by the projections formed by wires { ¹ , FIGS. 2 and 3.

Die vordere Wand B der Camera, welche das Objectiv aufnimmt, kann sich mit einer Feder in der Nuth a^x des Rahmens C verschieben, Fig. ι, um die Linse in der richtigen Höhenlage einstellen zu können; die Seitenwä'nde ' und die Bodenwand der Camera wer-The front wall B of the camera, which receives the objective, can move with a spring in the groove a ^{x of} the frame C , Fig. Ι, in order to be able to adjust the lens at the correct height; the side walls and the bottom wall of the camera are

Claims

formed by the collapsible, flexible panels j j j, which is closed by the upper ceiling k made of flexible fabric that is attached to it. The connection of the side walls j and the bottom wall with the front frame C is also made of flexible material, which at the same time seals the joints so that no rays of light can get into the interior of the camera. A diaphragm / with opening m and a smaller diaphragm r1 for the lens can also be accommodated in the camera. The visor disk η is articulated to a bar ρ at ο. The bar ρ runs in a dovetail groove so that the visor can be pushed forward for adjustment, but when the cassette is inserted, it can be pushed back. The visor plate, when it is folded up, FIG. 2, simultaneously forms the ceiling of the camera, so that a special cover plate can be saved. The camera is closed from behind by the board 5 and rests on the plate i, which in turn is attached to the tripod. When the camera is completely folded, the panels s and t form the front and rear sides of the camera. In order to use it, the folded camera is unfolded, the rear frame A is fixed in the correct position by means of the struts q and 1, Figs. 1 and 2, the front wall C is also opened and the lens is inserted in B. After the rear closing wall has been removed by folding it down, the visor is ready, Fig. 4. After this has been done, the visor is folded up (see Fig. 2), in which position it closes the top The camera forms and the cassette containing the photosensitive plates is then inserted into the camera, making sure that the buttons / i, of the cover plate b facing the inside of the camera, lie in the hooks g of the frame f Now the hooks ee are turned so that the inner flap b is free, while the rear flap b, which faces outwards, remains closed! Then you close the camera from behind again through the cover plate 5 and lift it by turning the handle i the front flap b upwards away from the light-sensitive plate. In order for the handle to remain in this position, one pushes the latch d1, Fig. 1. The position of the parts is then that shown in Fig. 2 told. If you now remove the cap placed on the lens, the exposure of the sensitive plate can take place. When the recording is finished, first the flap b is lowered again and then the cassette is removed from the camera by repeating the manipulations described above in reverse order. Of course, instead of lying to the side of the cassette, the frame f can also be arranged in front of the same or in a similar manner, without changing anything in the essence of the invention. The flexible material can also be provided with folds in the manner of a bellows and the side walls of the camera can also be replaced by such flexible material. You can also see the swinging frame f not inside the camera, but on the. Attach the cassette yourself or, after the cassette is in place, slide in the frame f afterwards. Pate nt-An s ρ ruche:

1. On photographic cassettes, the use of light-tight flaps b instead of the usual slides in connection with the swinging frame f in the rear part of the camera or on the cassette itself to open and close the flaps b.

2. In the case of collapsible bellows cameras, the arrangement of a hinged visor disc η rotatably suspended in the rear frame of such a size that it forms the solid ceiling of the bellows body of the camera and thereby creates the space for the unobstructed opening of the cassette flaps b described under 1.
