Description

Die Erfindung bezieht sich, auf photqgraphische Klappkammern, bei denen der Objektivträger beim Herunterklappen des Laufbodens selbsttätig in die Gebrauchsstellung übergeführt wird, sog. Springkameras. Besondere Vorrichtungen müssen vorgesehen sein, welche den Objektivträger sowohl wie die den Laufboden absteifenden Spreizen in der Gebrauchsstellung festhalten.
Die Erfindung bezweckt nun, die Festsetzung der Lauf bodenspreize sowohl wie des Objektivträgers in der Gebrauchsstellung durch ein einziges Organ zu bewirken. Zu diesem Zweck werden zweiarmige Hebel angeordnet, welche mit ihrem einen Ende die Laufbodenspreizen und mit dem anderen Ende den Objektivträger in der Gebrauchsstellung sichern. Vorteilhaft werden diese zweiarmigen Hebel auf den Zugstangen angeordnet, welche die Aufao richtung des Objektivträgers bewirken.The invention relates to hinged photographic chambers in which the lens carrier is automatically moved into the position of use when the floor is folded down, so-called jumping cameras. Special devices must be provided which hold the lens carrier as well as the struts that reinforce the walking floor in the position of use.
The invention now aims to fix the barrel base spreader as well as the lens carrier in the position of use by a single organ. For this purpose, two-armed levers are arranged, which with their one end spread the running floor and with the other end secure the lens carrier in the position of use. These two-armed levers are advantageously arranged on the tie rods, which cause the Aufao direction of the lens carrier.

Ein Ausführungsbeispiel der Erfindung ist auf der Zeichnung dargestellt, und zwar zeigt Abb. ι eine Seitenansicht der Kamera in Gebrauchsstellung,An embodiment of the invention is shown in the drawing, namely shows Fig. Ι a side view of the camera in the position of use,

Abb. 2 die Kamera in halb geöffnetem bzw. halb geschlossenem Zustande.Fig. 2 the camera in a half-open or half-closed state.

Mit ι ist das Kameragehäuse bezeichnet, an welchem mit Hilfe des Scharniers 2 der Laufboden 3 angelenkt ist. Auf dem Laufboden 3 ist ein Lagerbocks unveränderlich. angeordnet, welcher zwei um die Punkte 6 schwenkbare Hebel 7 besitzt, an welchen das Objektivbrett 8 angelenkt ist. Durch Zugstangen 9, welche mit ihrem einen Ende die Hebel 7 bei 10 gelenkig angreifen und mit ihrem anderen Ende bei ,26 am Gehäuse 1 drehbar gelagert sind, wird der Objektivträger beim Öffnen" des Laufbodens in bekannter Weise aufgerichtet.With ι the camera housing is referred to, on which with the help of the hinge 2 of Running floor 3 is articulated. A bearing block cannot be changed on the walking floor 3. arranged, which has two levers 7 pivotable about the points 6, to which the Lens board 8 is hinged. By tie rods 9, which one end of the lever 7 articulated at 10 and rotatable with its other end at 26 on the housing 1 are stored, the lens carrier is in a known manner when opening "the floor erect.

Die Spreizen- sind als Winkelhebel ausgebildet und am Gehäuse 1 bei 11 drehbar gelagert. Der kürzere Arm 12 dieser Spreizen steht .unter Einfluß von Federn 13, welche mit ihrem anderen Ende am Gehäuse 1 befestigt sind. Der längere Arm 14 der Sprei-ζ en ist bei 15 mit einem Auge 16 der Schubstangeng gelenkig verbunden. Diese Schubstangen 9 sind an beiden Seiten des Gehäuses und des Laufbodens angeordnet.The spreaders are designed as angle levers and are rotatably mounted on the housing 1 at 11. The shorter arm 12 of these spreaders is. Under the influence of springs 13, which are attached at their other end to the housing 1. The longer arm 14 of the Sprei-ζ en is at 15 with one eye 16 of the Schubstangeng articulated. These push rods 9 are arranged on both sides of the housing and the walking floor.

Die Sicherung der Laufbodenspreizen einerseits und des Objektivträgers andererseits in der Gebrauchsstellung erfolgt erfindungsgemäß gleichzeitig durch zweiarmige Hebel 17, welche bei 18 drehbar auf den Schubstangen 9 befestigt sind und durch. Federn 19 in der Pfeilrichtung gedrückt' werden. Durch an den Schubstangen 9 angebrachte Führungsschlitze 20, welche an Augen 16 der Hebel 9 The securing of the tread spreaders on the one hand and the lens carrier on the other hand in the position of use takes place according to the invention at the same time by two-armed lever 17, which are rotatably mounted at 18 on the push rods 9 and through. Springs 19 in in the direction of the arrow '. Through guide slots 20 attached to the push rods 9, which are attached to the eyes 16 of the levers 9

Claims

are provided, the spreading arms 14 out with the help of the pins 15 and in the end position of the walking floor on the further movement prevented when the pin 15 strikes the end of the slot 20. The SicheV approximately lever 17 are at her the spreader for turned end formed such that the pins 15 of the spreader arms 14 by snapping a catch 21 (see Fig. 2) are secured against any movement. The other, the end of the lever 17 facing the lens carrier has a detent 22 which the lever 7 in the position of use by pins 23 which are attached to the lever 7, fixes. At the same time, the lens board 8 is secured by pins 24 attached to it. fixed.

The function of the device described is as follows:

When the camera is opened, the walking floor moves into the position of use and straightens while the lens carrier in a known manner. When the end position is reached the lens carrier as well as the spreader by the lever 17 simultaneously and inevitably fixed by simultaneously snapping the catch 21 into the pin 15 and the catch 22 in the pins 23 and 24.

A particularly expedient arrangement of the device can be brought about in that the safety lever 17 is attached only on one side, ie only on a push rod 9, whereby the handling when closing the camera is considerably simplified. The camera is closed by pressing the tab 2 ζ bent out of the safety lever 17, against the pressure of the springs 19, whereby the lens carrier as well as the spreaders are released, so that all parts are released by pivoting the barrel base into the camera housing return to their resting position. If only one safety lever is used, closing is, of course, much easier, since only one safety / lever 17 is triggered by finger pressure

ity needs grounding.
