Zusatz zum Patent 412237.Addendum to patent 412237.

Patentiert im Deutschen Reiche vom 6. Juni 1924 ab. Längste Dauer: 19. März 1942. Patented in the German Empire on June 6, 1924. Longest duration: March 19, 1942.

Durch Patent 412237 ist ein Schwingestativ für photographische Reproduktionskameras geschützt, dessen Besonderheit darin besteht, daß der Träger für die Kamera und das Reißbrett einesteils seine nachgiebige Abstützung durch Federn erhält, die sich innnerhalb der Vertikalebene des Trägers befinden und das Kippen des nur in seiner Vertikalachse federnd abgestützten Trägers durch senkrechte Führungen erfolgt, die an breit ausladenden Fußgestellen angebracht sind.By patent 412237 is a rocking tripod for photographic reproduction cameras protected, the specialty of which is that the carrier for the camera and the drawing board is on the one hand its flexible Supported by springs located within the vertical plane of the beam and the tilting of the beam, which is resiliently supported only in its vertical axis, is carried out by vertical guides which are attached to wide base frames are attached.

Mit der Erfindung wird angestrebt, die Verwendung der besonderen Gleit- und Rollbahnführungen unnötig zu machen und dem Stativ ein weicheres, die geringste Erschütterung ausgleichendes Schwingen zu ermögliehen und ferner die Möglichkeit zu schaffen,The aim of the invention is to use the special slide and runway guides unnecessary to make and the tripod a softer, the slightest shock to enable balancing swinging and also to create the possibility of

unter Beibehaltung der federnden Unterstützung des Trägers innerhalb seiner Vertikalachse den Druck auf seitlich angeordnete Federn zu übertragen.while maintaining the resilient support of the carrier within its vertical axis to transfer the pressure to laterally arranged springs.

Dementsprechend kommen gemäß der Erfindung zwei Gruppen von Federn zur Anwendung, und zwar in solcher Weise, daß die eine Federgruppe zur Abstützung und die andere zweckmäßig rechtwinklig zur ersten ίο angeordneten Federgruppe als senkrechte Führung dient.Accordingly, according to the invention, two groups of springs are used, in such a way that the one spring group for support and the other is expediently at right angles to the first ίο arranged spring group serves as a vertical guide.

Auf der Zeichnung ist die Erfindung in zwei Ausführungsbeispielen dargestellt.The invention is shown in two exemplary embodiments in the drawing.

Von den beiden Enden eines Trägers d führen Bolzen h abwärts, die sich in der Vertikalachse des Trägers d befinden. Die Bolzen h werden von dem Fußgestell g umschlossen, die bei der Ausführungsform nach Abb. 1 am Kopfende einer den Bolzen h umso schließenden Stützfeder/ als Auflage dient, so daß der Träger d an dieser Stelle durch die Feder / in seiner Mittellage zum Fußgestell g gehalten wird. Am unteren Ende des Bolzens h greifen Federn i an, die zu ihm eine rechtwinklige Lage einnehmen und ihn so in senkrechter Stellung sichern.From the two ends of a beam d , bolts h lead downwards, which are located in the vertical axis of the beam d . The bolts h are enclosed by the pedestal g , which in the embodiment according to Fig. 1 at the head end of a support spring / which closes the bolt h in such a way that the support d is at this point by the spring / in its central position relative to the pedestal g is held. At the lower end of the bolt h , springs i attack, which assume a position at right angles to it and thus secure it in a vertical position.

Bei der Ausführungsform nach Abb. 2 sind die unteren Führungsfedern i beibehalten, und nur am Kopfende des Fußgestelles g sind an Stelle der einen Feder / mehrere Stützfedern k angebracht, die sich oben gegen den zweiarmigen Hebel m legen, der an dem Bolzen h um den Zapfen η schwingbar angebracht ist. Durch Verwendung des zweiarmigen Hebels m werden die ungleichen Schwingungen der Stützfedern k ausgeglichen und Verwindungsbeanspruchungen von dem Träger d ferngehalten.In the embodiment according to Fig. 2, the lower guide springs i are retained, and only at the head end of the base g instead of one spring / several support springs k are attached, which lie above against the two-armed lever m , which is attached to the bolt h around the Pin η is attached to swing. By using the two-armed lever m , the unequal vibrations of the support springs k are balanced and torsional stresses are kept away from the carrier d.
