Stativstab, flexibelTripod rod, flexible Beschreibung:Description:

Die nachfolgend beschriebene Erfindung betrifft einen Stativstab, mit dem ein an seinem Ende befestigtes Objekt, z.B. ein Sensor oder eine Strahlquelle exakt zu einem anderen Objekt positioniert werden kann, wobei in einem begrenzten Umfeld die Objekte jede beliebige Stellung zueinander einnehmen können.The invention described below relates to a tripod rod with which an object attached to its end, e.g. a sensor or a beam source, can be positioned exactly in relation to another object, whereby the objects can assume any position relative to one another within a limited environment.

Im Laborbetrieb werden üblicherweise Objekte einander zugeordnet, indem sie an Stangen befestigt und mit Klemmen positioniert werden. Eine genaue und richtungsunabhängige Positionierung ist nur mit mehreren Gelenkstellen möglich, wobei die Fixierung der Gelenkstellen nicht ohne Einfluss auf die gewünschte Objektlage bleibt. Auch biegsame Stativstäbe, s. g. Schwanen= halse, erfüllen nicht die Anforderungen an eine exakte Positionierung, weil sie rückfedern und nur große Biegeradien erlauben.In laboratory operations, objects are usually assigned to one another by attaching them to rods and positioning them with clamps. Precise and direction-independent positioning is only possible with several joints, whereby the fixation of the joints does not remain without influence on the desired object position. Flexible tripod rods, so-called goosenecks, also do not meet the requirements for exact positioning because they spring back and only allow large bending radii.

Aufgabe der Erfindung soll deshalb sein, ein an einem biegsamen Stativstab befestigtes Objekt gegenüber einem anderen in jeder möglichen Richtung anzuordnen , wobei nach der Anordnung eine Fixierung ohne Lageänderung erfolgt.The object of the invention is therefore to arrange an object attached to a flexible tripod rod relative to another in any possible direction, whereby after the arrangement a fixation takes place without changing the position.

Gelöst wurde die Aufgabe dadurch, dass der Stativstab vielgliedrig ausgebil= det wurde und in seiner Achse ein Zugseil geführt ist ,das durch Spannen nach der gewünschten Einstellung die Einzelglieder miteinander verspannt. Da die Kugel eines jeden Gliedes in der Pfanne ihres Nachbargliedes liegt und die Seilkräfte vom Mittelpunkt jeder Kugel aus wirken, treten beim Spannen des Seiles keine Verstellkräfte auf.The problem was solved by designing the tripod rod with multiple links and having a tension cable running along its axis, which tightens the individual links to one another when tensioned to the desired setting. Since the ball of each link lies in the socket of its neighbouring link and the cable forces act from the centre of each ball, no adjustment forces occur when the cable is tensioned.

Die mit der Erfindung erzielbaren Vorteile liegen darin, die durch Verbiegen und Verdrehen eines Stativstabes erzeugte Form durch Drehen einer Rän= del mutter an seinem Ende rückwirkungsfrei fixieren zu können.The advantages that can be achieved with the invention are that the shape created by bending and twisting a tripod rod can be fixed without reaction by turning a knurled nut at its end.

Ein Ausführungsbeispiel des flexiblen Stativstabes zeigt Abbildung (1) in Ansicht und Teilschnitten, wobei nur eine Knickstelle geknickt dargestellt ist.An example of the flexible tripod rod is shown in Figure (1) in view and partial sections, with only one bend shown bent.

Im Endstück (1) ist das Zugseil (2) mit Schraube (3) befestigt Zugseil (2> durchläuft mehrere Glieder (4) und endet mit seinem Zugstück (5) in der Senkung des Gewindezapfens (6). Der Gewindezapfen (6) ist verschiebbar im Spannstück (7) gelagert und durch Stifte (8) gegen Verdrehung gesichert. Mit der Mutter (9) wird das Zugseil gespanntThe traction cable (2) is attached to the end piece (1) with a screw (3). The traction cable (2) runs through several links (4) and ends with its traction piece (5) in the recess of the threaded pin (6). The threaded pin (6) is slidably mounted in the tension piece (7) and secured against twisting by pins (8). The traction cable is tensioned with the nut (9).

Der neuerungsgemäße flexible Stativstab ist geeignet, an seinem Ende angebrachte Objekte beliebig zu positionieren und durch nur ein Spannelement rückwirkungsfrei zu fixieren.The new flexible tripod rod is suitable for positioning objects attached to its end as desired and fixing them without any reaction using just one clamping element.

Tripod rod, characterized in that its members ( 4 ) are designed as a ball on one side and as a socket on the other side, the ball of one member lying in the socket of the adjacent member and being braced together by a centrally guided tension cable ( 2 ) with the aid of a tensioning member ( 9 ). 2. Stativstab, dadurch gekennzeichnet, dass die Kugeln seiner Glieder (4) konische Senkungen (10) besitzen, die im Mittelpunkt der Kugeln enden und einen Winkel haben, der dem Knickwinkel (11) entspricht. 2. Tripod rod, characterized in that the balls of its members ( 4 ) have conical depressions ( 10 ) which end in the center of the balls and have an angle which corresponds to the bend angle ( 11 ).
