Description
Fotografisches Stativ Die Erfindung betrifft ein fotografisches Stativ mit einem Stativkörper und mindestens drei abspreizbaren und in diskreten Winkelstellungen verrnstbaren Stativbeinen, welche im oberen Teil ein Langloch aufweisen, durch welches eine Schwenkachse hindurchgreift gemäß Patent (Patentanmeldung P 20.40 126.7). Photographic tripod The invention relates to a photographic tripod with a tripod body and at least three spreadable and in discrete angular positions Removable tripod legs, which have an elongated hole in the upper part through which a pivot axis reaches through according to patent (patent application P 20.40 126.7).
Ein derartiges Stativ ist aus der DT-OS 2 040 1,?6 bekannt.Such a tripod is known from DT-OS 2 040 1,? 6.
Das dort dargestellte Stativ hat den Nachteil, daß bei Abklappen und Verrasten der Stativbeine unter großen Winkeln zur Stativachse infolge der großen Hebellänge zwischen Schwenkachse und Verrastungsstiften und der damit verbundenen großen Momente kein hinreichend stabiler Stand des Stativs erzielbar ist.The tripod shown there has the disadvantage that when folding down and Locking of the tripod legs at large angles to the tripod axis due to the large Lever length between pivot axis and locking pins and the associated A sufficiently stable stand of the tripod cannot be achieved for large moments.
Der Erfindung liegt die Aufgabe zugrunde, diesen Nachteil zu vermeiden. Dies wird erfindungsgemäß dadurch erreicht, daß die Stativbeine am inneren Ende einen parallel zur Schwenkachse verlaufenden Querbolzen aufweisen, der in entsprechende Ausnehmungen des Stativkörpers verrastbar ist.The invention is based on the object of avoiding this disadvantage. This is achieved according to the invention in that the tripod legs are at the inner end have a cross bolt running parallel to the pivot axis, which is inserted into the corresponding Recesses of the stand body can be locked.
Gemäß einer besonderen Ausbildung der Erfindung weist der Stativkörper in einem Inneren einen senkrecht nach unten verlaufenden,zentral angeordneten, vorzugsweise zylindrischen Fortsatz auf. er eine vorzugsweise verstellbare rinnenförmige Ausnehmung besitzt, in die der Querbolzen bei nnnShernd rechtwinkeliger Abspreizung der StPtivbeine eingreift.According to a particular embodiment of the invention, the stand body in an interior a centrally arranged, preferably one that runs vertically downwards cylindrical extension. he a preferably adjustable channel-shaped recess in which the transverse bolt is inserted when the legs are splayed at right angles intervenes.
Erfindungsgemäß ist also vorgesehen, bei der Verrastung der Stativbeine unter großen Winkeln zur Stativachse eine zusätzliche Anlage fläche vorzusehen. Dies erhöht die Stabilität des Stativs.According to the invention it is therefore provided when the tripod legs are locked to provide an additional contact surface at large angles to the tripod axis. This increases the stability of the tripod.
Weitere Einzelheiten und Vorteile der Erfindung können dem in der Zeichnung dargestellten Ausftlhrungsbeispiel entnommen werden. Es zeigen: Fig. 1 einen senkrechten Schnitt durch den mittleren Teil des Stativs im erich des Stativkörpers; Fig. 2 einen horizontalen Schnitt durch ein Stativbein nach der Linie II-II in Fig. 1.Further details and advantages of the invention can be found in the The exemplary embodiment shown in the drawing can be taken. They show: FIG. 1 a vertical section through the middle part of the tripod in the erich of the tripod body; FIG. 2 shows a horizontal section through a tripod leg along the line II-II in FIG. 1.
Das Stativbetn 1 besteht aus einem U-förmigen oder runden Metallprofil, an dessen innerem Ende ein Querbolzen 2 befestigt ist. In einigem Abstand von diesem Querbolzen 2 und parallel zu diesem sind in dem Stativbein 1 Langlöcher 3 angeordnet, durch die sich eine fest mit dem Stativkörper 4 verbundene Schwenkachse 5 erstreckt. Jedes Stativbein 1 weist darUber hinaus auf der dem Querbolzen 2 bezüglich des Langloches 3 entgegengesetzten Seite einen Stift C) auf, der auf beiden Seiten über ds Ststivbein 1 hinausragt.The tripod bed 1 consists of a U-shaped or round metal profile, a cross bolt 2 is attached to its inner end. At some distance from this Cross bolts 2 and parallel to this are arranged in the tripod leg 1 elongated holes 3, through which a pivot axis 5 fixedly connected to the stand body 4 extends. Each tripod leg 1 also points to the cross bolt 2 with respect to the elongated hole 3 on the opposite side a pin C), which on both sides over the stanchion leg 1 protrudes.
Im Stativkdrper 4 ist eine nach oben verlaufende Stativ säule 7 befestigt, auf der ein KAmera-Auflageteller oder ein sonstiger StPtivkopf befestigbar ist. Entgegengesetzt hierzu verläuft ein senkrechter Ansatz 8 nach unten.In the tripod body 4 an upwardly extending tripod column 7 is attached, on which a KAmera support plate or other support head can be attached. In the opposite direction, a vertical extension 8 runs downwards.
In diesem Ansatz 8 ist eine Schraube mit Tellern 9 und 10 eingeschraubt, wobei die Oberkante 10a des Tellers 10 so eingestellt werden kann, daß bei Anliegen der Oberkante des Stativbeines 1 an der Kante 4n des Stativkörpers 4 der Querbolzen 2 an ihr anliegt. Der Zwischenrtum zwischen der Oberkante des Tellers 10 und der Unterkante des Tellers 9 ist etwAs größer als der Durchmesserjdes Querbolzens 2.In this approach 8 a screw with plates 9 and 10 is screwed, wherein the upper edge 10a of the plate 10 can be adjusted so that when applied the upper edge of the tripod leg 1 on the edge 4n of the tripod body 4 of the cross bolt 2 rests against her. The gap between the upper edge of the plate 10 and the The lower edge of the plate 9 is somewhat larger than the diameter of the transverse bolt 2.
Im Stativkörper 4 ist in einer Ebene senkrecht zur Schwenkachse 5 Je eine Platte 14 vorgesehen die Ausnehmungen 11, 11' und 11" aufweist. in die der Querbolzen 2 einrastbar ist.The stand body 4 is in a plane perpendicular to the pivot axis 5 One plate 14 each is provided which has recesses 11, 11 'and 11 "in which the Cross bolt 2 can be locked.
Die Ausnehmung 11 hat eine etwas weitere Öffnung als die Ausnehmungen 11' und 11". Aur der Verbindungslinie zwischen dem Mittelpunkt dieser Ausnehmung 11 und der Schwenkachse 5 ist seitlich des Schlitzes. in dem die Stativbeine 1 im Stativkörper 4 verschwenkbar sind, eine Ausnehmung 12 angeordnet, in die die vorstehenden Ansätze des Stiftes 6 einrastbar sind. Hierdurch wird buch für diese Winkelstellung eine besonders sichere Verrastung erreicht. Eine Zugfeder 13, die einerseits an der Achse 5, andererseits am Stift 6 befestigt ist, zieht die Stativbeine 1 in Richtung der Stativachse und damit in Verrastungsstellung.The recess 11 has a slightly wider opening than the recesses 11 'and 11 ". Aur the line connecting the center of this recess 11 and the pivot axis 5 is on the side of the slot. in which the tripod legs 1 in Stand body 4 are pivotable, a recess 12 is arranged into which the above Approaches of the pin 6 can be locked. This will book for this angular position one particularly secure locking achieved. A tension spring 13 on the one hand on the axis 5, on the other hand attached to the pin 6, pulls the tripod legs 1 in the direction of Tripod axis and thus in the locked position.
