Description

Gegenstand der Erfindung ist ein Kinoaufnahme oder -wiedergabeapparat, bei dem der Handgriff der Kurbel durch· seinen Lagerteil hindurch, verschieb- oder in diesem um· schraubbar sich befindet und durch seinen Eingriff in eine Aussparung des Gehäuses den gesamten Antriebsmechanismus sperrt, so daß ein selbsttätiges Lösen der dadurch geschaffenen Sicherung ausgeschlossen ist.The invention relates to a cinema recording or playback apparatus in which the Handle of the crank through its bearing part, sliding it or in this by is screwable and by its engagement in a recess of the housing locks the entire drive mechanism, so that an automatic release of the created thereby Backup is excluded.

Die· Neukonstruktion ist in einem Ausführungsbeispiel zeichnerisch wiedergegeben. Die Zeichnung stellt einen teilweisen mittleren Längsschnitt durch die Gesamteinrichtung dar.The · redesign is in one embodiment graphically reproduced. The drawing represents a partial central longitudinal section through the entire facility represent.

Im Kinogehäuseteil α sind die Bildbandaufnahme- und Abgabegehäuse b, c untergebracht, während im Gehäuseteil ä1 sich das Antriebswerk d befindet. Eine Sicherung oder Festlegung der Schaltwerkteile in ihrer Lage ist dadurch ermöglicht, daß der Griff/ ao der Kurbel fl als Feststellmittel eingerichtet ist. Zu diesem Zweck ist der Kurbelgriff / in seinem Befestigungslager /2 verschiebbar vorgesehen, so daß er mit einer Aussparung a2 des Gehäuses a1 zum Eingriff gebracht werden kann und so die weitere Bewegung des Antrieb- und Schaltwerkes vollständig ausschließt. Es können auch mehrere solcher Aussparungen in der Kreisbahn der Kurbel vorgesehen werden, und man kann die Kurbel statt verschiebbar so einrichten, daß sie durch leichte Drehung schraubenförmig in ihrem Lager /2 sich bewegt und mit ihrem inneren Ende /3 sich' gegen die Wan-In the cinema housing part α , the picture tape receiving and dispensing housings b, c are accommodated, while the drive mechanism d is located in the housing part ä 1. Securing or fixing the switchgear parts in their position is made possible by the fact that the handle / ao of the crank f l is set up as a locking means. For this purpose, the crank handle / in its mounting bearing / 2 is provided so that it can be brought into engagement with a recess a 2 of the housing a 1 and thus completely excludes further movement of the drive and switching mechanism. Several such recesses can also be provided in the circular path of the crank, and instead of being slidable, the crank can be set up so that it moves helically in its bearing / 2 by turning it slightly and its inner end / 3 is against the wall.

Außer diesen zwei Ausführungsformen der Kurbelfeststellart können auch noch andere Feststellungsweisen nach Art des Erfindungsgedankens verwendet werden.tion of the housing α 1 presses. In addition to these two embodiments of the crank locking type, other types of locking can also be used according to the concept of the invention.
