Description

Stativ Die vielfach gebräuchlichen und vorwiegend von Liebhaberphotographen verwendeten Flachstative wurden schon derart ausgeführt, daß sich die drei Füße wie auch eine allseitig neigbare Aufsatzplatte durch Betätigung einer einzigen Schraube festklemmen ließen. Zu diesem Zweck wurde auch schon eine festklemmbare und die Köpfe aller drei Stativbeine gemeinsam durchdringende Querachse angeordnet.Tripod The widely used and predominantly by amateur photographers The flat tripods used have already been designed in such a way that the three feet as well as a top plate that can be tilted in all directions by actuating a single screw clamped. For this purpose a clampable and the Heads of all three tripod legs arranged together penetrating transverse axis.

Die Erfindung bezweckt, bei einem derartigen Stativ die nach außen vorstehenden Teile möglichst zu vermeiden, ferner eine geringe Bauhöhe bei gleichzeitig großer Klemmwirkung zu erzielen und außerdem einfache und billig herstellbare Bauteile zu verwenden.The invention aims at such a tripod to the outside Avoid protruding parts as much as possible, and also a low overall height at the same time To achieve great clamping effect and also simple and inexpensive to manufacture components to use.

Dies wird erfindungsgemäß dadurch erreicht, daß die Gelenkköpfe der beiden äußeren Stativbeine und der :Gelenkkopf des Aufsatzteils Schalenringe umfassen, zwischen denen als Drehzapfen dienende Kugelsegmente gelagert sind, die ihrerseits um die hohle, die Achse der Klemmschraube aufnehmende Querachse drehbar sind.This is achieved according to the invention in that the joint heads of both outer tripod legs and the: the articulated head of the attachment section encompass cup rings, between which serving as pivot pin ball segments are mounted, which in turn are rotatable about the hollow transverse axis receiving the axis of the clamping screw.

Die Zeichnung zeigt ein Ausführungsbeispiel des Gegenstandes der Erfindung, und zwar: Abb. r die auf der Achse auseinandergezogenen Hauptbestandteile, Abb. a eine Ansichtszeichnung des Gelenkes, Abb.3 einen senkrechten und Abb.4 einen waagerechten Schnitt durch das Gelenk. -Auf der hohlen Querachse a sitzen längsverschieblich Schalenringe b, zwischen diesen als Kugelsegmente ausgebildete Drehzapfen c (Abb. :4) für die beiden äußeren Füße d und für das Aufsatzstück e. Der mittlere Fuß f (Abb.2) ist nicht drehbar auf die Achse a aufgesetzt und umfaßt mit seinen in axialer Richtung nachgiebigen Enden das dem Aufsatzstück e zugeordnete Schalenpaar. Eine an sich bekannte Klemmschraube k erzeugt einen Axi,al-druck aaf die Schalenringe b und ist entweder unmittelbar in die ganz oder teilweise hohl ausgeführte Querachse a eingeschraubt oder steht durch eine besondere Ausgleichshülse L (Abb. 4) mit einer gleichartigen Gegenschraube in Verbindung. Für gewöhnlich werden auch die Enden der beiden äußeren Beine d und des Aufsatzstückes e quer zur Achse a nachgiebig sein, so da(i an dieser und den Stirnflächen der Zapfen c zusätzliche Reibungsdrücke entstehen. Weiter ist in AM. 2 angedeutet, daß statt eines runden Aufsatztellers eine für Flachstative bekannte drehbare Aufsatzplatte i verwandt werden kann. Der das Aufschraubgewinde tragende Zapfen h ist in Abb. 3 angedeutet. Abb. q. zeigt, wie die Köpfe der Stativfüße in den Ge?.'-t'_l@(1,:°i äChn'ltt eingefugt sind sowie :lie großen Durchmesser der Reibungsflächen an den Kugelsegmenten c. Aus Abb. a ist ferner der Raumgewinn für die Ausziehteile g ersichtlich, welche sich bei dieser Anordnung unmittelbar bis an das Gelenk heranbringen lassen.The drawing shows an embodiment of the subject matter of the invention, namely: Fig. R the main components exploded on the axis, Fig. A a view drawing of the joint, Fig.3 a vertical and Fig.4 a horizontal section through the joint. - On the hollow transverse axis a, shell rings b sit longitudinally displaceable, between these pivot pins c designed as spherical segments (Fig.: 4) for the two outer feet d and for the top section e. The middle foot f (Fig. 2) is not rotatably placed on the axis a and, with its ends that are flexible in the axial direction, encompasses the pair of shells assigned to the top piece e. A clamping screw k known per se generates an axial pressure aaf the shell rings b and is either screwed directly into the fully or partially hollow transverse axis a or is connected to a similar counter screw by a special compensating sleeve L (Fig. 4). Usually the ends of the two outer legs d and of the top section e will also be flexible transversely to the axis a, so that additional frictional pressures arise on this and the end faces of the pin c. Furthermore, A M. 2 indicates that instead of one round top plate a rotatable top plate i known for flat tripods can be used. The pin h carrying the screw-on thread is indicated in Fig. 3. Fig. q. shows how the heads of the tripod feet in the Ge? .'- t'_l @ (1 ,: ° i äChn'ltt are inserted as well as: the large diameter of the friction surfaces on the ball segments c. The gain in space for the pull-out parts g can also be seen from Fig.
