Description
Die Erfindung betrifft eine Vorrichtung zur Fernauslösung von Objektivverschlüssen mittels Fadenzug. .The invention relates to a device for remote release of lens shutters by means of String. .
Es ist bekannt, zu diesem Zweck an dem Verschlußauslösehebel einen Verlängerungsarm anzubringen, an dessen freiem Ende der Abzugfaden befestigt wird. Bei dem bekannten Fernauslöser dieser Art wird der Verlängerungsarm an dem Verschlußauslösehebel festgeklemmt. ίο Diese Befestigungsart ist j edoch nur für Hochoder Querformataufnahmen verwendbar.It is known to have an extension arm on the shutter release lever for this purpose to be attached, at the free end of which the trigger thread is attached. With the well-known remote shutter release in this way the extension arm is clamped to the shutter release lever. ίο This type of fastening is, however, only for Hochoder Landscape format recordings can be used.
Um den Abzughebel sowohl für Hoch- als auch für Queraufnahmen verwenden zu können, trägt nach der Erfindung der Verschlußauslösehebel oder ein daran angebrachtes Metallscheibchen zwei senkrecht zueinander stehende Bohrungen zum Einstecken des Verlängerungsarmes. In order to be able to use the trigger for both portrait and landscape photography, carries according to the invention of the shutter release lever or a metal disk attached to it two perpendicular holes for inserting the extension arm.
Die Zeichnung zeigt eine Ausführungsform ao der Vorrichtung, und zwar Abb. 1 für Hoch-, Abb. 2 für Queraufnahmen, Abb. 3 die Führung des Abzugfadens.The drawing shows an embodiment of the device, namely Fig. 1 for high, Fig. 2 for transverse shots, Fig. 3 the guide of the pull-off thread.
An dem Verschlußauslösehebel sind entweder unmittelbar oder an einem aufgelöteten Metallstück zwei zueinander senkrechte Bohrungen a, b für Quer- und Hochaufnahmen angebracht. Durch die für die betreffende Aufnahme passende Bohrung wird als Verlängerungsarm ein Drahte gesteckt, der die Länge des Hebelarmes etwa verfünffacht. Zur besseren Sichtbarmachung seiner Bewegungen trägt der Verlängerungsarm an seinem freien Ende eine Signalscheibe d. Von dem freien Hebelarm oder der Signalscheibe wird der Abzugfaden durch eine möglichst unterhalb der Kamera, aber getrennt von ihr und dem Stativ, festgelegte öse (Stuhllehne, Henkel einer Kameratasche o. dgl.) geleitet und zum Standort des Photographen weitergeführt. Der lange Hebelarm erleichtert einen erschütterungsfreien Abzug der Schnur. Two mutually perpendicular bores a, b for transverse and vertical shots are attached to the shutter release lever either directly or on a soldered-on piece of metal. A wire, which increases the length of the lever arm approximately fivefold, is inserted as an extension arm through the hole suitable for the receptacle in question. To make its movements more visible, the extension arm carries a signal disc d at its free end. From the free lever arm or the signal disc, the trigger thread is guided through an eyelet (chair back, handle of a camera bag or the like) that is fixed below the camera, but separate from it and the tripod, and continues to the location of the photographer. The long lever arm facilitates a vibration-free withdrawal of the line.
