Description
Bekannt sind Vorrichtungen zum Feststellen der Stativrohre mittels Klemmeinrichtungen, die aus Kugeln, Kegeln und Keilringen bestehen. Die meisten dieser Vorrichtungen haben Teile, die sich infolge ihrer eigenartigen Anordnung nur durch Stürzen des Stativs voneinander lösen, andere haben schwer zu bewegende Klemmringe usw.Devices for fixing the stand tubes by means of clamping devices are known, which consist of balls, cones and wedge rings. Most of these devices have parts that, due to their peculiar arrangement, can only be lifted when the Detach tripods from each other, others have clamping rings that are difficult to move, etc.
Bei keiner der bekannten Vorrichtungen ist es möglich, das Stativrohr sofort nach dem Ausziehen durch eine kleine Drehung in der gewünschten Stellung zu sichern und nach dem Gebrauch in derselben Stellung zu entsichern. Dieser Vorteil wird gemäß der Erfindung im wesentlichen dadurch erreicht, daß der mit den Kugeln zusammenwirkende Kegel mit dem untersten Fußende verbunden ist, das an seiner oberen Kante eine Kurvenführung hat. Auf dieser Kurvenführung gleitet ein Stift, der mit dem um seine Längsachse drehbaren Ausziehrohr verbunden ist. Durch die Drehung des Ausziehrohrs wird hierbei eine die Klemmwirkung des Kegels und der Kugeln betätigende Feder ein- oder ausgeschaltet. In none of the known devices is it is possible to turn the stand tube into place immediately after pulling it out to secure the desired position and to unlock after use in the same position. According to the invention, this advantage is achieved essentially by that the cone cooperating with the balls is connected to the lowest foot end is that has a curve guide on its upper edge. On this curve guide slides a pin which is connected to the extension tube which is rotatable about its longitudinal axis. By the rotation of the extension tube is the clamping effect of the cone and the Ball actuating spring on or off.
Des weiteren betrifft die Erfindung Ausbildungen dieser Feststellvorrichtung.The invention also relates to embodiments of this locking device.
Die Zeichnung zeigt den Gegenstand der Erfindung ,an einem Ausführungsbeispiel, und zwarThe drawing shows the subject matter of the invention, using an exemplary embodiment, and though
Abb. ι einen Stativfuß in Längsschnitt und Abb. 2 eine Außenansicht des unteren Fußendes. Fig. Ι a tripod base in longitudinal section and Fig. 2 is an external view of the lower foot end.
Am Stativkopf 1 ist das Außenrohr 2 (Abb. 1), wie üblich, angelenkt. Darin befrndet sich ein Einsatzrohr 10, indem das Innenrohr 3 geführt ist. Im Innern des Innenrohres 3 ist eine Stange 9 angeordnet, die erfindungsgemäß den untersten Fußteil 11 mit dem Klemmkegel 4 für die Kugeln 5 verbindet. Diese Klemmkugeln 5 liegen in einem als Kugelhalterring dienenden Einsatzrohr 6 und greifen außerdem durch Löcher des Innenrohres 3 und des ,äußeren Einsatzrohres 10 hindurch, so daß sie an der Innenwand des Außenrohres 2 anliegen.As usual, the outer tube 2 (Fig. 1) is hinged to the tripod head 1. In it an insert tube 10 in which the inner tube 3 is guided. Inside the inner tube 3 a rod 9 is arranged, which, according to the invention, the lowermost foot part 11 with the clamping cone 4 for the balls 5 connects. These clamping balls 5 are in one serving as a ball retainer ring insert tube 6 and also reach through holes in the inner tube 3 and the outer insert tube 10 through so that they are on the inner wall of the Outer tube 2 are in contact.
Die Stange 9 hat in ihrem unteren Teil ein Schraubengewinde 18, auf das eine Schraubenmutter 16 aufgeschraubt ist. Diese Schraubenmutter 16 füllt unten das Innere des Innenrohres 3 .aus und ist mit diesem durch einen Stift 13 verbunden, dessen herausstehendes Ende mittels einer Kurve 17 (Abb. 2) des untersten' Fußteiles 11 geführt wird.The rod 9 has in its lower part a screw thread 18 on which a screw nut 16 is screwed on. This nut 16 fills the inside of the inner tube at the bottom 3 .aus and is connected to this by a pin 13, the protruding The end is guided by means of a curve 17 (Fig. 2) of the lowest 'foot part 11.
Außerdem befindet sich an der Stange 9 ein Bund 7, der das obere Gegenlager einer Schraubenfeder 8 bildet, die unten durch die Schraubenmutter 16 abgestützt ist.In addition, there is a collar 7 on the rod 9, which is the upper counter bearing of a Forms helical spring 8, which is supported by the screw nut 16 below.
Wird das Stativ aufgestellt, so wird das Innenrohr 3 nach Bedarf ausgezogen. Dreht man nun das Ausziehrohr 3 so, daß der Stift 13 die in Abb. 2 dargestellte Lage einnimmt, so nimmt hierbei der Stift 13 die Schraubenmutter 16 mit, welche hierdurch die Stange 9 nach oben treten läßt, so daß die Feder 8 sie hinauf drückt und dadurch mittels desIf the tripod is set up, the inner tube 3 is pulled out as required. Turns the extension tube 3 is now so that the pin 13 assumes the position shown in Fig. 2, so here the pin 13 takes the nut 16 with it, which thereby drives the rod 9 can step up, so that the spring 8 pushes it up and thereby by means of the
Kegels 4 die Kugeln fest an die Innenwand des Außenrohres 2 drückt. Hierdurch wird der Stativfuß in der eingestellten Länge festgestellt. Will man ihn wieder zusammenschieben, so verdreht man mittels des Fußteiles 11 die mit ihr verbundene Stange 9 in entgegengesetzter Richtung mit Bezug auf das Innenrohr 3 und die mit diesem verbundene Schraubenmutter 16, wodurch die Stange 9 entgegen der Wirkung der Feder 8 nach unten gezogen wird, so daß der Kegel 4 die Kugeln 5 freigibt.Cone 4 presses the balls firmly against the inner wall of the outer tube 2. This will the stand base is fixed in the set length. If you want to push it together again, so by means of the foot part 11, the rod 9 connected to it is rotated in the opposite direction Direction with respect to the inner tube 3 and the screw nut 16 connected to it, whereby the rod 9 against the action of the spring 8 is pulled down, so that the cone 4 the balls 5 releases.
