Description

Die vorliegende Erfindung betrifft die Stative, deren Kopf einen auf einem Kugelgelenk angebrachten Halter aufweist, damit man den Photoapparat o. dgl., der an diesem Halter befestigt werden soll, nach, allen Richtungen einstellen und neigen kann.The present invention relates to tripods whose head has a has a ball joint attached holder so that you can use the camera or the like, to be attached to this holder, adjust in all directions and may tend.

Bei manchen derartigen Stativen ist die Gelenkkugel in einer merklich halbkugelförmigen Schale eingeschlossen, und es kommt vor, daß ihre Schwenkbewegung manchmal durch das Eindringen von Staub zwischen die aufeinander reibenden Flächen erschwert wird. Insbesondere wenn die Vorrichtung auf der Landstraße benutzt wird, wird ihr Arbeiten häufig durch in der Luft umherfliegenden Mineralstaub gestört.In some of these tripods, the joint ball is noticeable in one hemispherical shell enclosed, and it happens that their pivoting movement sometimes through the penetration of dust between the surfaces rubbing against each other is made more difficult. Especially when the device is used on the country road, Their work is often disrupted by mineral dust flying around in the air.

Dieser Übelstand wird gemäß vorliegender Erfindung durch eine besondere Ausbildung der Gelenkkugel und ihrer Auflageorgane vermieden.According to the present invention, this disadvantage is caused by a particular one Avoided training of the joint ball and its supporting organs.

Hierfür sind die Auflagepunkte der halbkugeligen Gelenkkugel auf drei kleine Pastillen beschränkt, die vorzugsweise aus einem bildsamen Werkstoff bestehen und an dem Kopf des Stativs befestigt sind, wobei die Gelenkkugel auf diese Pastillen mittels eines in der Achse dieses Kopfes angeordneten Bolzens gepreßt werden kann. Ein Ende dieses Bolzens ruht mit einer kugeligen Fläche in einem im geometrischen Zentrum der Gelenkkugel angebrachten Hohlraum entsprechender Form. wobei die Stange des Bolzens frei eine konische Ausnehmung der Gelenkkugel durchdringt, deren Winkel genügend offen ist, um die gewünschten Neigungen dieser Kugel zuzulassen. Schließlich schraubt sich das untere Ende des Bolzens in den Kopf des Stativs oder trägt eine Mutter, die sich unter diesen Kopf legt, so daß die Gelenkkugel kräftig auf diese Pastillen gedrückt werden kann, um sie in jeder beliebigen gewählten Stellung festzustellen. Dieser Bolzen kann auch durch eine beliebige geeignete Betätigungsvorrichtung mit Zahnrädern o. dgl. in lotrechter Richtung verstellt werden.For this purpose, the support points of the hemispherical joint ball are on three limited small pastilles, which preferably consist of a malleable material and attached to the head of the tripod, with the joint ball on these lozenges can be pressed by means of a bolt arranged in the axis of this head. One end of this bolt rests with a spherical surface in a geometric one Center of the joint ball attached cavity of appropriate shape. being the rod of the bolt freely penetrates a conical recess of the joint ball, the angle of which is sufficiently open to allow the desired inclinations of this sphere. In the end the lower end of the bolt screws into the head of the tripod or carries one Mother, who lies under this head, so that the joint ball is strongly on this Lozenges can be pressed to lock them in any chosen position. This bolt can also be connected by any suitable actuating device Gears or the like. Be adjusted in the vertical direction.

Unter diesen Umständen besteht keine Gefahr, daß das Arbeiten jemals durch die Anwesenheit von Staub oder Fremdkörpern zwischen den Auflageflächen gestört werden kann.Under these circumstances there is no danger that the work will ever happen disturbed by the presence of dust or foreign bodies between the contact surfaces can be.

Eine Ausführungsform eines derart ausgebildeten Stativs ist als Beispiel auf der Zeichnung dargestellt.An embodiment of a tripod designed in this way is an example shown on the drawing.

Abb. i ist ein Axialschnitt des Stativoberteils; Abb. 2 ist ein Grundriß des Kopfes allein.Fig. I is an axial section of the stand top; Fig. 2 is a plan of the head alone.

i bezeichnet den Kopf beliebiger Form, der von den Füßen 2 getragen wird und auf welchem an drei an den Spitzen eines Dreiecks gelegenen Punkten Pastillen 3 aus bildsamer Masse in einer gegen die Mitte zu geneigten Stellung befestigt sind. Auf diesen. Pastillen ruht die halbkugelige Fläche der Gelenkkugel 4, in deren Achse eine halbkugelige, zu der Fläche der Gelenkkugel konzentrische Höhlung und eine konische Ausnehmung 6 vorgesehen sind. wobei die Ausnehmung sich von dem Boden der Höhlung 5 an für den Durchtritt des Festziehbolzens 7 erweitert.i denotes the head of any shape that is carried by the feet 2 and on which lozenges at three points at the tips of a triangle 3 are fixed from plastic mass in a position inclined towards the center. On this. Pastilles, the hemispherical surface of the joint ball 4 rests in its axis a hemispherical cavity concentric to the surface of the joint ball and a conical recess 6 are provided. the recess extending from the bottom of the Cavity 5 widened for the tightening bolt 7 to pass through.

Dieser Bolzen besitzt einen kugeligen Kopf 8, der in die Höhlung 5 paßt, und eine Mutter 9, die sich unter den Kopf legt.This bolt has a spherical head 8 which is inserted into the cavity 5 fits, and a mother 9, who lies under her head.

Auf dem Oberteil der Gelenkkugel ist ein Halter io angebracht, der um eine mit der Achse der Gelenkkugel zusammenfallende Achse schwenkbar ist. An diesem Halter ist ein weiterer Halter i i gelenkig befestigt, der um eine zu den vorhergehenden Achsen senkrechte Achse schwenkbar ist und an welchem der Aufnahmeapparat o. dgl. befestigt wird.A holder io is attached to the upper part of the joint ball is pivotable about an axis coinciding with the axis of the joint ball. At this holder is another holder i i hinged to one to the previous axes vertical axis is pivotable and on which the receiving apparatus o. The like. Is attached.

Es ist wohlverstanden, daß die Erfindung von der Form und der Ausbildung des Teiles des Kopfes i, der die Auflagepunkte 3 trägt, sowie der Halter io und i i unabhängig ist. In bestimmten Fällen können diese letzteren Halter übrigens fortfallen, wobei dann das Oberteil der Gelenkkugel zur unmittelbaren Aufnahme des zu verwendenden Apparates eingerichtet wird.It is well understood that the invention of the shape and the training of the part of the head i, which carries the support points 3, and the holder io and i i is independent. Incidentally, in certain cases these latter holders can omitted, in which case the upper part of the joint ball for the immediate inclusion of the device to be used is set up.
