Description

Stativ Gegenstand der Erfindung ist ein Stativ, insbesondere für Kinokameras, bei dem der Kameratisch, um ein bewegliches Ziel zu verfolgen, sowohl um die horizontale als auch um die vertikale Achse schwenkbar ist. Um die Bewegung des Kameratisches zu dämpfen, d. h. um ruckweise Bewegungen des Tisches zu vermeiden, hat man bisher vorgeschlagen, sowohl der vertikalen als auch der horizontalen Bewegung des Kameratisches verschieden große Schwüngmasseri zuzuordnen, die man, je nach der Schnelligkeit der Bewegung, zu- oder abkuppelte: Die vorliegende Erfindung geht aus von einer Einrichtung, bei der für die horizontale und die vertikale Bewegung des Kameratisches nur je eine einzige Schwungmasse benötigt wird. Um dabei eine Änderung der Dämpfungsintensität zu erreichen, werden erfindungsgemäß zwischen Antrieb und Schwungmassen Geschwindigkeitswechselgetriebe, vorzugsweise Reibradgetriebe, eingeschaltet. Die Verwendung von Schwungmassen verschiedenen Gewichtes, wie es bisher geschah, wird also dadurch ersetzt, daß eine Schwungmasse mit verschiedenen Umdrehungszahlen umläuft. Sowohl bei Benutzung eines Zahnradgetriebes als auch eines Reibradgetriebes lassen sich beliebig viel Übersetzungen erreichen, die bei der Verwendung einer einzigen Schwungmasse Feinheiten der Änderung der Dämpfungsintensität schaffen, wie es bei den bisher bekannten Anordnungen nicht möglich war. Besonders trifft dies natürlich bei der Verwendung von Reibradgetrieben zu. Die Zeichnung veranschaulicht ein Ausführungsbeispiel der Erfindung. Der Kameratisch 13 des Stativs i ist mittels des Knüppels q. über das Zahnradgetriebe 6 horizontal, über das im Stativteil3 gelagerte Segmentgetriebe 5 vertikal beweglich. Zwischen diesen Getrieben 6 und 5 und der jeder Tischbewegung zugeordneten Schwungmassel' bzw. l ist ein als keibradgetriebe ausgebildetes Geschwindigkeitswechselgetriebe 8', 9', i o', i i', 12' bzw. f, C), i o, i i, 12 eingeschaltet. Mist 2, 2', 2" sind ,die Stativfüße angedeutet.Tripod The invention relates to a tripod, in particular for cinema cameras, in which the camera table can be pivoted about both the horizontal and the vertical axis in order to track a moving target. In order to dampen the movement of the camera table, ie to avoid jerky movements of the table, it has been proposed so far to assign different sized swing masses to both the vertical and the horizontal movement of the camera table uncoupled: The present invention is based on a device in which only a single flywheel is required for the horizontal and vertical movement of the camera table. In order to achieve a change in the damping intensity, according to the invention, speed change gears, preferably friction gears, are switched on between the drive and the flywheel. The use of centrifugal masses of different weights, as has happened so far, is replaced by the fact that a centrifugal mass revolves at different speeds. Both when using a gear transmission and a friction wheel transmission, any number of translations can be achieved, which create subtleties in the change in the damping intensity when using a single flywheel, as was not possible with the previously known arrangements. This is particularly true of course when using friction gears. The drawing illustrates an embodiment of the invention. The camera table 13 of the tripod i is by means of the stick q. Can be moved horizontally via the gear mechanism 6 and vertically via the segment gear 5 mounted in the stand part 3. Between these gears 6 and 5 and the flywheel 'or l associated with each table movement is a speed change gear 8', 9 ', i o', i i ', 12' or f, C), i o, ii, 12 switched on. Crap 2, 2 ', 2 "are, the tripod feet are indicated.
