Description

Die mit Federmotor angetriebenen Kinoaufnahmeapparate besitzen zur Betätigung des Aufzuges eine Kurbel oder einen Wirbelgrift" oder auch einen außen am Kameragehäuse schwenkbaren, mit Zahnstange versehenen Handgriff. Diese bekannten Aufzugselemente stehen aber mehr oder weniger über die Außenflächen der Kamera vor.
Um eine bequeme Handhabung des Aufzuges zu erzielen, wird erfindungsgemäß ein in der Uhrtechnik bekannter, um die Federmotorachse schwenkbarer, mit Sperrkegel versehener Aufzugshebel vorgesehen, der in der Kamerawand vertieft gelagert ist und seine Aufzugsbegrenzung zugleich durch die vertiefte Lagerung erhält.The spring motor-driven cinema recorders have a crank or a "swivel grip" or a rack-and-pinion handle that can be pivoted on the outside of the camera housing.
In order to achieve comfortable handling of the elevator, according to the invention an elevator lever, known in watch technology, pivotable about the spring motor axis and provided with a locking cone, is provided, which is recessed in the camera wall and at the same time receives its elevator limitation from the recessed mounting.

Der Aufzugshebel α ist auf der Federmotorachse b schwenkbar gelagert und bewegt sich mit seinem freien Ende außerhalbThe elevator lever α is pivotably mounted on the spring motor axis b and moves with its free end outside

ao des Kameragehäuses zwischen den .vertieften Anschlagsbegrenzungen t und t1. Das auf der Achse gelagerte, mit Sperrkegel versehene Ende liegt innerhalb, also unterhalb der Kamerawand. Das außen in der Vertiefung liegende schwenkbare Schenkelende ist mit einer nach dem Gehäuse zu angebogenen Fingerschaufel versehen, die beim Schwenken des Aufzugshebels nach Anschlag t in dem freien Raum des Kameragehäuses zu stehen kommt und dadurch in keiner Weise vorsteht. Die Anschläge sind so angeordnet, daß beim Schwenken des Aufzugshebels α vom Anschlag t zu Anschlag t1 das Federwerk so viel aufgezogen wird, daß bei jeder einzelnen Schwenkbewegung, je nach der festgelegten Anschlagsbegrenzung, der Ablauf von 1Z.,, 1J.., 1Z4 oder 1Zn Meter Film erfolgt.ao of the camera housing between the recessed limit stops t and t 1 . The end, which is mounted on the axle and provided with a locking cone, is inside, i.e. below the camera wall. The pivotable leg end lying outside in the recess is provided with a finger shovel bent towards the housing, which comes to rest in the free space of the camera housing when the elevator lever is pivoted to stop t and thus does not protrude in any way. The stops are arranged in such a way that when the lift lever α is pivoted from stop t to stop t 1, the spring mechanism is pulled up so much that with each individual pivoting movement, depending on the defined stop limit, the sequence of 1 Z. ,, 1 J .. , 1 Z 4 or 1 Z n meter of film takes place.

Durch diese Einrichtung ist man in der Lage, schon beim Aufzug des Federmotors festzulegen, wieviel Meter Film ablaufen sollen. Ist die Begrenzung der Vertiefung z. B. so gehalten, daß auf eine Schwenkbewegung der Aufzug des Werks für den Ablauf von 1Z4 Meter Film erfolgt, und es sollen 2V2 Meter Film für eine Aufnahme verwendet werden, so sind zehn Schwenkbewegungen beim Aufzug des Motors zu machen.This facility enables you to determine how many meters of film should run when the spring motor is being lifted. Is the limitation of the recess z. B. held so that on a pivoting movement of the elevator of the factory for the sequence of 1 Z 4 meters of film takes place, and 2V 2 meters of film are to be used for a recording, then ten pivoting movements are to be made when the elevator of the motor.
