Description
Filmspule Bei bekannten Filmspulen. die vorwiegend iit Kameras verwendet werden, ist der Filni entweder an bzw. in dem Spulenkern festkleinnibar. wobei zur Betätigung der Filmhaltevorrichtung ein Ausbruch im Spulenkern vorgesehen ist, oder er kann mit Zähnen in Eingriff gebracht werden, die auf dem Spulenkern angebracht sind und in die Lochung des Films oder in das Filmmaterial selbst eingreifen.Film reel With known film reels. which mainly used iit cameras the Filni can either be attached to or in the coil core. where for Actuation of the film holding device a breakout is provided in the spool core, or it can be engaged with teeth mounted on the spool core and engage in the perforation of the film or in the film material itself.
Die Erfindung gellt nun aus von edier Filmspule, in deren Hohlkern der durch cincn Schlitz- eingeführte Filmanfang festlesbar ist und eine zur Freigabe des Films von au0:en betätigbare Feder aiigeoi-dnet ist, und hat zur .;ttfgabe, die Anordnung so zu treffen, dal.') das richtige Einlegen des Films c#rle:chtert und eine sichere Festlegung des Filmanfanges gewährleistet ist. Erreicht wird d:e s dadurch, d.i1@ erfindungsgemäß innerhalb des Spulenkerns mindestens ein den Film durchgreifender Zahn und noch eine zweite Feder vorgesehen sind, welche mit der ersten am Fulae dieses Zahnes attlie-eildcii Feder ein Maul bildet und den Film gegen unbeahsichtigtes Aushän gen aus diesem Zahn sichert. Beide Federn können dabei so angebracht sein, dalli sie sich in Fortführung des Kernschlitzes <in die Innenwandung des Spul, nkerns anschmiegen.The invention is now compensated for by edier film reel, in its hollow core the beginning of the film inserted through the cincn slot can be read and one for release of the film is aiigeoi-dnet operable spring from the outside, and has to.; ttfgabe, to make the arrangement so that. ') the correct insertion of the film c # rle: chtert and a secure definition of the beginning of the film is guaranteed. What is achieved is d: e s thereby, d.i1 @ according to the invention within the coil core at least one the film penetrating tooth and a second spring are provided, which with the first at the fulae of this tooth attlie-eildcii spring forms a mouth and the film secures against unintended unhooking from this tooth. Both springs can do this be attached so that they are in continuation of the core slot <in the inner wall of the bobbin core.
In der Zeichnung ist der Erfindungsgegenstand in einem Ausführungsbeispiel dargestellt, und -zwar zeigen Abb. i und 2 einen Schnitt durch den Spulenkern mit zwei werscliicdeneli Stellungen der Filmbefestigungsvorrichtung und Ahb.3 eine Seitenansicht eines 'fcJs der Spule. Der Spulenkern- i besitzt den Schlitz ; zum Einführcii des Filins 2 sowie den Ausbruch 1. An der Innemu-and des Spulenkcrns i sitze@it der eiiiseiti' abgeschriigte Zahn 5, die 111rittfecier 6 mit dem Ausbruch ; sozt-ie die lllzittfecler S. Durch den Schlitz ; wird der Filiii 2 zu-ischen die Blattfedern 6 und S #eschob"n, I gleitet hierbei über den abgeschrägten Zahn ; und hängt sich dann mit seiner Lochung in dcitsclitcn (-in. Die mit dem Ausbruch ; für den Zahn 5 versehene Blattfecler 6 übergreift den Kopf des Zahnes 5 und verhindert (-in Aushängen des Films. Zum lfisen des Films z «wird durch den Ausbruch 4. auf die Blattluder S gedrückt. die von dem- Zahnful-; her deil Film von dein Zahn 5 abstreift, «-ccrauf der Film zwischen den Blattfedern huraus-ezc,gen werden kann.In the drawing, the subject matter of the invention is shown in an exemplary embodiment, and indeed Figs. 1 and 2 show a section through the spool core with two different positions of the film fastening device and Fig. 3 shows a side view of a part of the spool. The coil core i has the slot; for the introduction of the filin 2 as well as the breakout 1. On the inside of the bobbin case there is the one-sided tooth 5, the step 6 with the breakout; sozt-ie the lllzittfecler S. Through the slit; If the filiii 2 is attached to the leaf springs 6 and S #eschob "n, I slides over the beveled tooth; and then hangs with its perforation in the dcitsclitcn (-in. The leaf spring 6 provided for the tooth 5 overlaps the head of tooth 5 and prevents (-in unhooking of the film. To run the film z "is pressed through the breakout 4. on the blade slug S which from the tooth ful-; -ccrauf the film between the leaf springs can be removed-ezc, gen.
