Claims (1)

Das Ausrichten eines optischen Instrumentes auf seinem Gestell geschieht meistens mittels eines Kugelgelenkes, das in seinem Lager durch Überwurfmutter oder gleichwertige Einrichtungen in jeder beliebigen Lage festgestellt werden kann. Diese Feststellung entbehrt der nötigen Sicherheit, wenn es sich um schwerere Instrumente handelt oder um solche, bei denen der Schwerpunkt verhältnismäßig hoch über demAligning an optical instrument on its frame is usually done by means of a ball joint that is in its bearing through Union nut or equivalent devices can be determined in any position can. This statement lacks the necessary certainty when it comes to heavier instruments or those where the center of gravity is relatively high above the ίο Kugelmittelpunkt liegt.ίο is the center of the sphere. Es liegt nun nahe, die Gelenkkugel nach unten hin mit einem Fortsatz zu versehen, der an seinem Ende in eine Kugel ausläuft.' Auf diese läßt man dann vier kreuzweise angeordnete Stellschrauben wirken, mittels deren man das Kugelgelenk beliebig verstellen und auch gleich-" zeitig feststellen kann.It now makes sense to provide the joint ball with a downward extension that is on ends in a ball. ' On this one then leaves four arranged crosswise Adjusting screws act, by means of which the ball joint can be adjusted as desired and also equal- " can determine early. Die Berührungspunkte zwischen dem Kugelfortsatz und den — notwendigerweise planen — Druckflächen der Stellschrauben sind aber sehr klein, und deshalb werden nach kurzer Zeit die Druckflächen der Schrauben verschleißen und dann ein sicheres Arbeiten der Einrichtung unmöglich machen.The points of contact between the spherical extension and the - necessarily plan - The pressure areas of the adjusting screws are very small and therefore become shorter after a while Time the pressure surfaces of the screws wear out and then the safe working of the Make setup impossible. In der vorliegenden Erfindung ist deshalb die eben erwähnte Klemmkugel durch einen Kreuzzylinder ersetzt, d. h. durch zwei gekreuzte Zylinderflächen, die senkrecht zueinander und gleichzeitig senkrecht zur Instrumentenachse stehen. Aus der beiliegenden Zeichnung (Fig. ι und 2) ist ohne weiteres ersichtlich, daß die Vorrichtung genau so wirkt wie die oben beschriebene Klemmkugel, nur mit dem vor-"' teilhaften Unterschied, daß die Berührungsflächen zwischen den Druckflächen der Stellschrauben und dem Kreuzzylinder erheblich größer sind.In the present invention, therefore, the aforementioned clamping ball is formed by a cross cylinder replaced, d. H. by two crossed cylindrical surfaces that are perpendicular to each other and at the same time be perpendicular to the instrument axis. From the accompanying drawing (Fig. 1 and 2) it is readily apparent that the device works exactly like the one above described clamping ball, only with the advantageous "'part difference that the contact surfaces between the pressure surfaces of the adjusting screws and the cross cylinder are considerably larger. Ρλτε ν τ-Anspruch:Ρλτε ν τ-claim: - Einstellbares Kugelgelenk für Gestellköpfe u. dgl., dadurch gekennzeichnet, daß der zur Verstellung der Gelenkkugel dienende Fortsatz der letzteren als Kreuzzylinder ausgebildet ist, zu dem Zweck, eine größere und sichere Anlagefläche für die vier Stellschrauben zu schaffen.- Adjustable ball joint for frame heads and the like, characterized in that the extension of the latter, which is used to adjust the joint ball, is designed as a cross cylinder is, for the purpose of a larger and safer contact surface for the four adjusting screws to accomplish.
