Den Gegenstand vorliegender Erfindung bildet ein Stativkopf mit drehbarem Teller. Neu ist die Anordnung eines den Teller in jeder Lage selbsttätig festlegenden Zwischengliedes, dessen Klemmwirkung durch Drehung eines Stativkopfteiles in der Richtung, in welcher der Stativkopfteller gedreht werden soll, aufgehoben werden kann.The subject matter of the present invention is a tripod head with a rotatable plate. New is the arrangement of an intermediate link that automatically fixes the plate in every position, its clamping effect by rotating a tripod head part in the direction in which the tripod head plate is to be rotated, can be canceled.
Mit drehbarem Teller zum leichten BewegenWith rotatable plate for easy movement
ίο des auf dem Stativ befestigten Apparates in horizontaler Richtung versehene Stativköpfe sind bekannt. Bei diesen bekannten Einrichtungen wurde, nachdem der Aufnahmeapparat in die richtige Stellung gebracht war, der bewegbare Teller durch eine Stellschraube oder ein ähnliches Mittel festgelegt. Durch dieses Feststellen des Tellers, wozu eine Kraftäußerung erforderlich war, wurde das Stativ bewegt, so daß sich Neueinstellungen des Aufnahmegegenstandes erforderlich machten.ίο of the device attached to the tripod in tripod heads provided in the horizontal direction are known. In these known facilities was, after the receiving apparatus was brought into the correct position, the movable plate by an adjusting screw or set a similar means. By this fixing of the plate, for which purpose an expression of force was required, the tripod was moved so that readjustments of the subject required.
Demgegenüber ist bei vorliegender Erfindung ein selbsttätig wirkendes Kiemmittel zwischen dem beweglichen Teller und dem die Stativspreizen tragenden Unterteil vorgesehen, welches an sich bekannte Klemmittel — es können Kugel-, Walzen- oder Backenklemmvorrichtungen in Benutzung genommen werden — durch einen horizontal drehbar lagernden Stativkopfteil ausgelöst werden kann.In contrast, in the present invention, an automatically acting gill means is between the movable plate and the lower part carrying the stand braces, which Clamping means known per se - ball, roller or jaw clamping devices can be used can be put into use - by means of a horizontally rotatable tripod head part can be triggered.
Auf der Zeichnung ist ein Ausführungsbeispiel der Neuerung dargestellt. Der Stativkopfunterteil ι trägt die Spreizen 2, des weiteren um den Zapfen 3 drehbar den Teller 4 mit Stiftschraube 5 zum Befestigen des Aufnahmeapparates. Unterhalb des Tellers 4 ist eine scheibenartige Verstärkung 6 vorgesehen,An exemplary embodiment of the innovation is shown in the drawing. The lower part of the tripod head ι carries the spreaders 2, furthermore the plate 4 rotatable about the pin 3 with stud screw 5 for attaching the receiving device. Below the plate 4 is a disk-like reinforcement 6 is provided,
welcher gegenüber im Unterteil 1 ein Stahlring 7 liegt. In Aussparungen der Verstärkung 6 ruhen beim Ausführungsbeispiel unter Wirkung einer Feder stehende Klemmbacken 8, welche ständig gegen den Stahlring 7 gedrückt werden. Lose drehbar über dem Unterteil 1 lagert des weiteren der einer Überwurfmutter ähnliche Teil 9, an welchen zwei Stifte 10 befestigt sind, die vor den Klemmbacken 8 liegen (Fig. 2). . .which is opposite in the lower part 1, a steel ring 7. In recesses in the reinforcement 6 rest in the embodiment under the action of a spring clamping jaws 8, which are constantly pressed against the steel ring 7. Loosely rotatable over the lower part 1 Furthermore, the part 9, similar to a union nut, to which two pins 10 are attached are, which are in front of the jaws 8 (Fig. 2). . .
Die Wirkungsweise der Vorrichtung ist kurz folgende: Soll der vermittels der Schraube 5 auf dem Teller 4 festgelegte Aufnahmeapparat bzw. soll der Teller 4 gedreht werden, dann ist nur erforderlich, daß der Teil 9 in der Richtung drehend bewegt wird, in welcher der Teller 4 eine Bewegung ausführen soll. Durch dieses Drehen des Teiles 9 wird der eine der beiden Stifte 10 gegen den ihm gegenüberliegenden Sperrteil (Backen) 8 gedrückt, wodurch wiederum die Wirkung dieses Backens aufgehoben wird. Da jeder der beiden Sperrteile 8 nur nach der einen Drehrichtung wirkt, kann nunmehr der Teller 4, mithin auch der Apparat, beliebig gedreht werden. Sobald der Teil 9 losgelassen wird, legt sich der Klemmteil, dessen Wirkung während der Drehbewegung aufgehoben wurde, wieder fest gegen den Stahlring 7, wodurch ein selbsttätiges Drehen des Aufnahmeapparates vollständig ausgeschlossen wird.Briefly, the method of operation of the device is as follows: Should the screw 5 the receiving device fixed on the plate 4 or if the plate 4 is to be rotated, then it is only necessary that the part 9 is rotatably moved in the direction in which the plate 4 is to perform a movement. By this turning of the part 9 is the one of the two pins 10 pressed against the opposite locking part (jaws) 8, which in turn negates the effect of this baking. As each of the two Locking parts 8 only acts in one direction of rotation, the plate 4 can now, therefore also the apparatus, can be rotated at will. As soon as part 9 is released, lays the clamping part, the effect of which was canceled during the rotary movement, again firmly against the steel ring 7, whereby an automatic rotation of the recording apparatus completely is excluded.
Es sei noch bemerkt, daß naturgemäß jedes bekannte Kiemmittel oder richtiger jede bekannte Vorrichtung zum Verbinden zweier Teile durch Klemmwirkung in Benutzung genommen werden kann, und daß auf der Zeich-It should also be noted that naturally every known gill remedy or, more correctly, every known Device for connecting two parts by clamping action taken into use can be, and that on the drawing
nung nur als Ausführungsbeispiel die Klemmvorrichtung mit Backen herausgegriffen wurde.The clamping device with jaws was picked out only as an exemplary embodiment.
