Description
Vorrichtung zum Heben und Senken photographischer Kameras am Stativ. Der Erfindungsgegenstand betrifft eine Hebevorrichtung für den Tisch größerer photographischer Kameras. Es ist an sich bekannt, auf der mit einem Handgriff versehenen Achse zur Verstellung des Fußes des Kameratisches in einer Führung des Statives eine Spiralfeder anzubringen, um durch deren Spannung eine Zugkraft auszuüben und dadurch die Verstellung des Kameratisches mit der Kamera zu erleichtern. Zur Verstellung des Kameratisches ist bei der bekannten Hebevorrichtung ein Zahntrieb angebracht. Um diesen zu vermeiden und auch jeden Handantrieb überflüssig zu machen, sind nach der Erfindung Federbänder einerseits an der Führung für den Fuß des Kameratisches, anderseits an Wickelbüchsen befestigt, welche mit im Fuße des Kameratisches angebrachten unter Einwirkung von Spiralfedern stehenden Trommeln verbunden sind.Device for raising and lowering photographic cameras on a tripod. The subject of the invention relates to a lifting device for the table of larger photographic ones Cameras. It is known per se, on the axis provided with a handle for Adjustment of the foot of the camera table in a guide of the tripod a spiral spring to be attached in order to exert a tensile force through their tension and thereby the adjustment the camera table with the camera to facilitate. For adjusting the camera table a pinion is attached to the known lifting device. To avoid this and to make any manual drive superfluous, spring hinges are according to the invention on the one hand on the guide for the foot of the camera table, on the other hand on winding sleeves attached, which with attached in the foot of the camera table under the action of Spiral springs are connected to standing drums.
In der Zeichnung ist ein Ausführungsbeispiel einer solchen Vorrichtung dargestellt, und zwar in Abb. i eine Ansicht des ganzen Stativs, in Abb. z ein Schnitt durch den Fuß des letzteren und in Abb. 3 im Querschnitt A-B von Abb. i.In the drawing is an embodiment of such a device shown, namely in Fig. i a view of the entire tripod, in Fig. z a section through the foot of the latter and in Fig. 3 in cross-section A-B of Fig. i.
Im Fuß a des Stativs, welcher in einer Führung b gleitet, sind Wickelbüchsen c gelagert, von denen Federbänder d zu beiden Seiten des Fußes nach oben geführt und an der Führung b befestigt sind. Jede der Wickelbüchsen c ist durch die Achse mit einer Trommel e verbunden, in welcher Spiralfedern f gelagert sind, die mit Hilfe von Sperrädern zweckmäßig nachspannbar sind.In the foot a of the stand, which slides in a guide b, there are winding sleeves c stored, of which spring straps d led upwards on both sides of the foot and attached to the guide b. Each of the winding sleeves c is through the axis connected to a drum e, in which coil springs f are mounted, which with With the help of ratchet wheels are expediently retensioned.
In der Führung ist ein Exzenter g gelagert, der durch einen Handhebel h an den Fuß gepreßt werden kann .und diesen in der gewünschten Lage festhält.An eccentric g is mounted in the guide, which is controlled by a hand lever h can be pressed against the foot and hold it in the desired position.
Die Wirkungsweise der Vorrichtung ist die, daß beim Zurückdrehen des Exzenters der Fuß mit dem Stativ selbsttätig von den unter Federwirkung stehenden Federbändern hochgezogen wird, welche sich auf die Wickelbüchsen c aufrollen. In der gewünschten Zwischenstellung wird der Fuß durch den Exzenter g festgestellt.The operation of the device is that when turning back the Eccentric the foot with the tripod automatically from those under spring action Spring strips are pulled up, which roll up on the winding sleeves c. In the foot is determined by the eccentric g in the desired intermediate position.
