Description
Eürbi & Niggeloh, Metallwarenfabrik, Radevormwald/Rhld.
Es ist bei fotografischen Stativen, insbesondere bei Kinostativen, bekannt, sich eines Neigekopfes zu bedienen, der in zwei zueinander senkrechten Ebenen, d. h. um zwei zueinander senkrechte Zapfen o. dgl. drehbar und dabei in beiden Drehrichtungen zugleich durch eine einzige Klemmspindel im Neigekopf sperrbar ist. With photographic tripods, especially cinema tripods, known to use a tilt head that is in two mutually perpendicular Levels, d. H. rotatable about two mutually perpendicular pins or the like and thereby in Both directions of rotation can be locked at the same time by a single clamping spindle in the tilt head is.
Von bekannten Stativen dieser Gattung unterscheidet sich der Erfindungsgegenstand
in vorteilhafter Weise dadurch, daß am Stativkopf bzw. an einer darin heb-und senkbaren
Mittel-
Ein solches Stativ hat den Vorteil einer gleichzeitigen Klemmung bzw. Blockierung beider Neigungsrichtungen des Neigekopfes. Es zeichnet sich jedoch dabei gegenüber bekannten Einrichtungen vergleichbarer Art durch einen sehr einfachen Aufbau aus. Es ist daher wohlfeil in der Herstellung und arbeitet störungsfrei. Such a tripod has the advantage of being clamped at the same time or blocking of both directions of inclination of the tilt head. It stands out, however compared to known facilities of a comparable type by a very simple one Construction from. It is therefore cheap to manufacture and works without any problems.
Auf der Zeichnung ist der Erfindungsgegenstand in einem Ausführungsbeispiel dargestellt. Und zwar zeigen : Fig. 1 ein Stativ mit Neigekopf in einer Seitenansicht, und Fig. 2 einen vergrösserten Teilschnitt durch den Neigekopf, wobei aus Gründen der Übersichtlichkeit die Ebene, in der sich der die Klemmspindel befindet, um 9o° in die Zeichenebene hineingeklappt ist. The subject of the invention is shown in one embodiment in the drawing shown. 1 shows a tripod with a tilt head in a side view, and FIG. 2 shows an enlarged partial section through the tilt head, with, for reasons For clarity, the level in which the clamping spindle is located by 9o ° is folded into the drawing plane.
Das in Fig. 1 abgebildete Stativ hat in üblicher Weise an einem Stativkopf
10 drei angelenkte, teleskopartig höhenveränderbare Stativbeine 11 sowie eine im
Stativkopf durch Kurbel 12 und Zahnstange 13 stufenlos heb-und senkbare Mittel-
Auf den beiden Bundteilen 2o, 21 des Bundbolzens lagert ferner ein
Gehäuse 23, das über einen verkröpfen Arm 24 den Stativteller 25 trägt, in dem der
durch einen Griff 26 drehbare Stativgewindezapfen 27 lagert
Quer zur Längsachse des Bundbolzens 19, 20, 21 ist in einem Muttergwinde einer Nabe 3o des Gehäuses 23 eine Klemmspindel 31 verschraubbar, die an ihrem hinteren Ende einen Handgriff 32 o. dgl. trägt, während ihr vorderes Spindelende eine Art Kugelpfanne 33 bildet, in der eine Druckkugel 34 ruht, welche zwischen die beiden Keilringflächen der beiden Druckbüchsen 28, 29 eingreift. Dabei Versteht es sich, daß die Klemmspindel 31 aus der in Fig. 1 sichtbaren richtigen Stellung bei der Darstellung nach Fig. 2 um 9o° in die Zeichenebene hineingeklappt ist. Transverse to the longitudinal axis of the collar bolt 19, 20, 21 is in a nut thread a hub 3o of the housing 23, a clamping spindle 31 screwable, which at its rear End of a handle 32 or the like. Carries, while its front spindle end a kind Forms ball socket 33, in which a pressure ball 34 rests, which between the two Wedge ring surfaces of the two pressure sleeves 28, 29 engage. It goes without saying that the clamping spindle 31 from the correct position visible in FIG. 1 in the Representation according to FIG. 2 is folded into the plane of the drawing by 90 °.
Befindet sich die Klemmspindel 31 in-ihrer Freigabestellung, in die sie durch leichtes'Linksdrehen gelangt, dann ist der Neigdkopf A in zwei zueinander senkrechten Richtungen frei drehbar. Und zwar vermag das Kreuzstück 17 sich in einer waagerechten Ebene um den Säulenzapfen 15 zu drehen, während das Gehäuse 23, welches sich an das Kreuzstück 17 genau wie die linke Druckbüchse 28 mit glatten Ringstirnflächen anschließt, in senkrechter Ebene um die Längsachse des Bundbolzens 19 frei drehbar ist. Man kann also in gewohnter Weise den Neigekopf A in allen Richtungen verschwenken und verdrehen. If the clamping spindle 31 is in its release position, in the if you turn it slightly to the left, the tilting head A is in two to one another freely rotatable in vertical directions. The cross piece 17 can be in one horizontal plane to rotate the pillar pin 15, while the housing 23, which to the cross piece 17 just like the left pressure sleeve 28 with smooth annular end faces adjoins, freely rotatable about the longitudinal axis of the collar bolt 19 in a vertical plane is. So you can swivel the tilt head A in all directions in the usual way and twist.
Dreht man dagegen die Klemmspindel 31 nach rechts, dann wird die Druckkugel 34 in den Keilhohlraum zwischen den beiden Druokbüchsen 28,29 hineingedrückt mit der Folge, daß infolge Keilwirkung die beiden Druckbüchsen 28, 29 auseinandergetrieben werden, weil durch deren Keilflächen Schiebekomponenten entstehen, die die Büchsen in entgegengesetzte Richtungen auseinanderzutreiben trachten. On the other hand, if you turn the clamping spindle 31 to the right, then the Pressure ball 34 is pressed into the wedge cavity between the two pressure sleeves 28, 29 with the result that the two pressure sleeves 28, 29 are driven apart as a result of the wedge effect because sliding components are created by their wedge surfaces that form the bushings seek to drive them apart in opposite directions.
Dabei drückt die in Fig. 2 rechte Büchse 29 gegen den Bundteil 2o des Bundbolzens 19,2o, 21 und versucht, diesen nach rechts zu führen. Die Folge hiervon ist, daß zwischen der Querbohrung 22 des, Bundbolzens und dem Lagerzapfen 15 der Säule 14 eine hohe Flächenpressung auf dem-linken Teil des Umfanges eintritt, die den Zapfen 15 in der Querbohrung 22 des Bundbolzens blockiert. The bushing 29 on the right in FIG. 2 presses against the collar part 2o of the collar bolt 19,2o, 21 and tries to lead it to the right. The consequence of this is that between the transverse bore 22 of the, collar bolt and the bearing pin 15 of the column 14 a high surface pressure occurs on the left-hand part of the circumference, which blocks the pin 15 in the transverse bore 22 of the collar bolt.
Zugleich wird aber die linke Druckbüchse 28 nach links geführt und dadurch mit ihrer Stirnfläche kräftig gegen die Ringstirnfläche des Kreuzstückes 17 gepreßt, so daß die linke Büchse 28 zwischen Kugel 34 und Stirnwand des Kreuzstückes 17 verspannt wird mit der Folge, daß sich das Gehäuse 23 durch Verspannung gegenüber dem bereits blockierten Kreuzstück 17 nicht mehr verdrehen kann. Der Neigekopf A ist somit in beiden Richtungen blockiert. Dabei treten die beiden Blockierungen gleichzeitig ein, weil die Druckkugel 34 gleichermaßen auf beide Druckbüchsen 28, 29 einwirkt. At the same time, however, the left pressure sleeve 28 is guided to the left and thereby with its end face strongly against the ring face of Cross piece 17 pressed so that the left sleeve 28 between the ball 34 and the end wall of the cross piece 17 is clamped with the result that the housing 23 is through Do not twist any more tension in relation to the already blocked cross piece 17 can. The tilt head A is thus blocked in both directions. The both blockages at the same time, because the pressure ball 34 is equally open both pressure sleeves 28, 29 acts.
