 und an demselben festzustellen. 



   Die Gelenkbohrungen zeigen sämtlich eine besondere Gestaltung, die aus Fig. 4 und 5 hervorgeht, indem die Bohrungsfläche den Gelenkzapfen nicht voll umfasst, sondern nur mit drei Backen 9, die den spezifischen   Flächendruck,   der durch das Anziehen der   Flügelschrauben   erzielt wird, steigern und so eine festere Verbindung möglich   machen.   Die drei Backen ersetzen   0 im   übrigen vollständig eine prismatisch gestaltete Führung. 



   PATENT-ANSPRÜCHE :
1. Untersatz zum mechanischen und optischen Zentrieren von Theodoliten über oder unter einem gegebenen Punkt unter Verwendung einer besonderen Aufstellungsvorrichtung, dadurch gekennzeichnet, dass eine gegen Herausfallen gesicherte,   federbeeinflusste,   kardanische Gelenke   (21)   tragende Haltevorrichtung mit dem Theodolit verschraubt werden kann. 



   2. Untersatz zum mechanischen und optischen Zentrieren von Theodoliten über oder unter

 and to be determined by the same.



   The joint bores all show a special design, which emerges from FIGS. 4 and 5 in that the bore surface does not fully encompass the pivot pin, but only with three jaws 9, which increase the specific surface pressure that is achieved by tightening the wing screws and so on make a stronger connection possible. The three jaws completely replace a prismatically designed guide.



   PATENT CLAIMS:
1. Base for the mechanical and optical centering of theodolites above or below a given point using a special installation device, characterized in that a spring-influenced cardanic joints (21) carrying holding device secured against falling out can be screwed to the theodolite.



   2. Base for mechanical and optical centering of theodolites above or below
 EMI2.2

Claims

Claim 1, characterized in that two articulated arms (5, 7) which can be rotated against each other and which allow adjustment at any point within the maximum range are used to connect the base to the fixed pivot point of the fixed bracket arm (1).

3. Base for the mechanical and optical centering of theodolites above or below a given point using a special installation device according to claim 1, characterized in that, instead of the two articulated arms, a double pipe clamp (29, 30) movably attached to the bracket arm by means of a pin or eye ) is provided, in which a tube (28) carrying the base of the theodolite is displaceable.

4. Stand for the mechanical and optical centering of theodolites above or below a given point using a special installation device according to claim l. characterized in that the member (1, 1) serving as a bearing for the articulated arm (5) EMI2.3
