Description

  Einrichtung an photographischen bzw. kinematographischen Kameras mit Antriebsmotor und Zusatzantrieb 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

    und Verschlussorganeablaufende Federwerk angetrieben wird,   treibt über ein weiteres Zahnrad 21 einen schematisch dargestellten Geschwindigkeitsregler 22 an, so dass der über ein Wendegetriebe 23 auf das Varioobjektiv 4 erfolgte Antrieb eine gleichmässige Bewegung aufweist. Das Wendegetriebe 23 dient dabei dem Vor- oder Rücklauf des Varioobjektivs. 



   Das Gehäuse 3 für das zusätzliche Federwerk 17 kann so ausgebildet sein, dass nach Ansetzen desselben an das Kameragehäuse   1,   der Auslöser 24 für das Kameratriebwerk sowohl mittels Finger als auch mittels Drahtauslöser betätigt werden kann. 



   Beim Drehen des Schlüssels 5 in einer Richtung können beide Federwerke gleichzeitig aufgezogen werden, es ist aber auch möglich, wie dies bereits an anderer Stelle vorgeschlagen wurde, dass in der einen Drehrichtung des Filmschlüssels 5 das eine Federwerk aufgezogen wird, während das zusätzliche Federwerk beim Drehen des Schlüssels 5 in der andern Drehrichtung aufgezogen wird. 



   Es liegt im Rahmen der Erfindung, dass statt der motorischen Verstellung der Glieder eines Varioobjektivs, mit denselben Mitteln die Betätigung entweder der Glieder für die Scharfeinstellung eines üblichen Objektivs, oder der   Stellmitteleines Kompendiumszwecks   Über-, Auf- und Abblenden bzw. anderer Trickeffekte möglich ist. Ebenso können auf diese Weise an die Kamera ansetzbare Titelgeräte angetrieben werden. 



    PATENTANSPRÜCHE :    
1. Einrichtung an photographischen bzw. kinematographischen Kameras mit einem Antriebsmotor für die den Filmlauf bewirkenden Transport- und Verschlussorgane sowie einem Zusatzantrieb, insbesondere für die Verstellung der Glieder eines Varioobjektivs zur Brennweitenänderung, dadurch gekennzeichnet, dass das zusätzliche Federwerk an der Kamera bzw. an der Fassung des Objektivs ansetzbar und mit einer mit dem Kameraantriebswerk getrieblich verbundenen Kupplungswelle kuppelbar ist.

  Installation on photographic or cinematographic cameras with drive motor and additional drive
 EMI1.1
 

 <Desc / Clms Page number 2>

    and the spring mechanism running off the closure member is driven, drives a schematically illustrated speed controller 22 via a further gear 21, so that the drive carried out via a reversing gear 23 on the varifocal lens 4 has a uniform movement. The reversing gear 23 serves to advance or reverse the zoom lens.



   The housing 3 for the additional spring mechanism 17 can be designed in such a way that after it has been attached to the camera housing 1, the trigger 24 for the camera drive mechanism can be actuated both with a finger and with a cable release.



   When turning the key 5 in one direction, both spring mechanisms can be wound up at the same time, but it is also possible, as has already been suggested elsewhere, that one spring mechanism is wound in one direction of rotation of the film key 5, while the additional spring mechanism is wound when turning of the key 5 is wound in the other direction of rotation.



   It is within the scope of the invention that instead of the motorized adjustment of the members of a varifocal lens, the same means can be used to actuate either the members for focusing a conventional lens or the adjusting means of a compendium purpose of fading in, fading in and out or other trick effects. Title devices that can be attached to the camera can also be driven in this way.



    PATENT CLAIMS:
1. Device on photographic or cinematographic cameras with a drive motor for the transport and closure elements causing the film to run, as well as an additional drive, in particular for adjusting the members of a zoom lens to change the focal length, characterized in that the additional spring mechanism on the camera or on the Mount of the lens can be attached and can be coupled to a coupling shaft which is geared to the camera drive mechanism.

Claims (1)

2. Einrichtung nach Anspruch l, dadurch gekennzeichnet, dass die Antriebswelle (13) für das zusätz- liche Federwerk (7) mit einem auf der Welle (13) sitzenden Zahnrad (14) durch eine Schlingfeder (15) verbunden ist. 2. Device according to claim 1, characterized in that the drive shaft (13) for the additional spring mechanism (7) is connected to a gear (14) seated on the shaft (13) by a wrap spring (15).
