Description

Die Erfindung betrifft ein -optisches Winkelmeßgerät, insbesondere einen Theodolit, mit drei im Fußteil gelagerten Fußschrauben zur Horizontaljustierung und einer amStativteller zubefestigenden Standplatte für die Fußschrauben.The invention relates to an optical angle measuring device, in particular a theodolite, with three foot screws mounted in the foot part for horizontal adjustment and a base plate to be attached to the tripod plate for the foot screws.

Bei diesen Geräten wird es noch als äußerst nachteilig empfunden, daß infolge des nie ganz zu vermeidenden Spiels im Fußschraubengewinde .ein wenn auch nur geringes Kippen .der Fußschrauben auftritt, was eine Verdrehung und Verschiebung des Dreifußes und damit des Theodolits in seiner Einstellebene (Horizontalen) bedeutet. Man hat deshalb für die Fußschraubenführung stets einen verhältnismäßig großen Aufwand treiben müssen, um diese zum weitestgehend spielfreien Arbeiten zu bringen. Diesem Bestreben war .aber in der Praxis eine Grenze gesetzt, die auf einen Kompromiß zwischen nicht zu schwerem Gang der Fußschrauben und festem Stand des Gerätes hinauslief.With these devices it is still felt to be extremely disadvantageous that as a result of the play in the foot screw thread, which can never be completely avoided, if only slight tilting of the footscrews occurs, resulting in a twisting and displacement of the tripod and thus of the theodolite in its setting plane (horizontal). One therefore always has a relatively large effort for the foot screw guide have to drive in order to bring them to work that is largely play-free. This one The aim was, but in practice a limit was set on a compromise between The foot screws did not run too hard and the device was in a firm position.

Der Erfindung liegt nun der allgemeine Gedanke zugrunde, die Fußschrauben von ihrer zusätzlichen Aufgabe, nämlich gleichzeitig den horizontalen Dreifußteil gegen Verdrehen und Verschieben in seiner Einstellebene zu sichern, zu entbinden und die Verdrehungssicherung in anderer Weise zu erreichen.The invention is based on the general idea, the foot screws of their additional task, namely at the same time the horizontal tripod to secure against twisting and shifting in its setting level, to release and to achieve the anti-twist protection in another way.

Gemäß der Erfindung stehen die Fußschrauben nicht mehr in Führungsrinnen, sondern auf Planflächen der Standplatte, und an der Standplatte sind gesonderte Mittel zur Sicherung des Dreifußes gegen Verdrehen und Verschieben in seiner Einstellebene vorgesehen.According to the invention, the foot screws are no longer in guide channels, but on flat surfaces of the base plate, and on the base plate are separate Means for securing the tripod against twisting and shifting in its setting plane intended.

Diese Sicherungsmittel können z. B. aus drei in Dreiecksform angeordneten einarmigen Hebeln bestehen, welche mit ihren aufeinanderfolgenden Enden, vorzugsweise über Kugelzapfen, abwechselnd an dem Dreifußteil und an der Standplatte befestigt sind.These security means can, for. B. of three arranged in a triangular shape one-armed levers exist, which with their successive ends, preferably Via ball studs, alternately attached to the tripod and to the base plate are.

Dieses Ausführungsbeispiel ist in den Abb. i bis 3 der Zeichnung wiedergegeben.This embodiment is shown in Figs. I to 3 of the drawing.

Mit i ist der als Dreifuß ausgebildete Fußteil eines Theodolits bezeichnet. Der Theodolit selbst ist in seinen Einzelheiten nicht näher dargestellt. Er kann, wie durch die Bohrung 2 im Fußteil angedeutet, in letzteren einsetzbar ausgebildet sein. Im Fußteil sind die drei Fußschrauben 3, .l, 5 zur Horizontierung des Theodolits gelagert. Sie stehen mit ihren kugeligen Enden 6 auf Planflächen 7 der am Stativteller befestigten Standplatte B. Wie insbesondere aus den Abb. 2 und 3 ersichtlich, sind zwischen Dreifußteil i und Standplatte 8 drei einarmige Hebel 9, io und i i ,angeordnet, und zwar iri Dreiecksform derart, daß immer ein Hebel zwischen zwei Fußschrauben zu liegen kommt. Mit ihren aufein.anderfolgenden Enden i2 bis 17 sind sie über Kugelzapfen 18 abwechselnd an dem Dreifuß i (13, 15, 17) und an der Standplatte 8 (12, 14, 16) befestigt. Diese Hebelanordnung bewirkt, daß nach der Horizontierung des Dreifußteils i keine Verdrehung und keine Verschiebung .dieses Teils mehr in seiner Einstellebene (Horizontalen) möglich ist. Das Halten des Dreifußes an der Grundplatte wird durch eine oder mehrere Federn i 9 bewirkt.The foot part of a theodolite, designed as a tripod, is designated by i. The theodolite itself is not shown in detail. As indicated by the bore 2 in the foot part, it can be designed to be used in the latter. The three foot screws 3, .l, 5 for leveling the theodolite are stored in the foot part. They stand with their spherical ends 6 on flat surfaces 7 of the stand plate B attached to the tripod plate. As can be seen in particular from Figs. 2 and 3, three one-armed levers 9, io and ii, are arranged between tripod i and stand plate 8, namely in a triangular shape in such a way that a lever always comes to rest between two foot screws. With their successive ends i2 to 17 they are alternately attached to the tripod i (13, 15, 17) and to the base plate 8 (12, 14, 16) via ball studs 1 8. This lever arrangement has the effect that after the tribrach part i has been leveled, no rotation or displacement of this part is possible in its setting plane (horizontal). The tribrach is held on the base plate by one or more springs i 9.
