Description

Vorrichtung zum gleichzeitigen Bohren zweier rillenartiger Vertiefungen von geringem Abstand für zahnärztliche Zwecke. Die Erfindung betrifft eine Vorrichtung zum gleichzeitigen Bohren zweier rillenartiger Vertiefungen von geringem Abstand für zahnärztliche Zwecke, und besteht darin, daß über die zum einen Bohrer senkrecht gelagerte und diesen mittels Zahnradübersetzung drehende Antriebswelle eine Hülse verschiebbar und feststellbar gezogen ist. Diese Hülse vermag mittels Zahnradübersetzung den gegenüber dem ersten parallel mit sich selbst verschieblichen und in geeignetem Abstande einstellbaren zweiten Bohrer anzutreiben und wird durch einen in die Antriebswelle eingelassenen Keil von dieser rnitgedreht. Auf der Zeichnung ist der Erfindungsgegenstand beispielsweise dargestellt, und zwar zeigt: Abb. i eine Ansicht des Doppelbohrers und Abb. a einen Schnitt nach der Linie A-B der Abb. i.Device for drilling two groove-like recesses at the same time close up for dental purposes. The invention relates to a device for the simultaneous drilling of two groove-like recesses close to each other for dental purposes, and consists in the fact that on the one hand the drill is perpendicular mounted and this by means of gear transmission rotating drive shaft a sleeve slidable and lockable is pulled. This sleeve is capable of gear transmission the one that can be moved parallel to itself and in a suitable manner compared to the first Drives spaced adjustable second drill and is inserted through one into the drive shaft Recessed wedge turned from this. The subject of the invention is on the drawing shown for example, namely shows: Fig. i a view of the double drill and Fig. a is a section along the line A-B of Fig. i.

Der Bohrer c ist feststehend gelagert, während der Bohrer d durch Lösen der Schrauben e und f sowie Verschieben des Teiles k auf dem feststehenden Teil l in geeignetem Abstande zum Teil m einstellbar ist. Zu diesem Zwecke ist über die senkrecht zum Bohrer c gelagerte und diesen mittels Zahnradübersetzung drehende Antriebswelle eine auf dem einen Ende eine Verzahnung tragende Hülse h verschiebbar und feststellbar gezogen, welche durch einen in die Antriebswelle g eingelassenen Keil i mitgenommen wird und so mittels der Zahnradübersetzung an ihrem Ende den Bohrer d antreibt. Der Teil l ist mit dem hier nicht eingezeichneten Handgriff starr verbunden.The drill c is fixedly mounted, while the drill d can be adjusted by loosening the screws e and f and moving the part k on the fixed part l at a suitable distance to part m. For this purpose, a sleeve h bearing a toothing on one end is slidably and lockably pulled over the drive shaft, which is mounted perpendicular to the drill c and rotates it by means of a gear ratio, which is taken along by a wedge i embedded in the drive shaft g and so on by means of the gear ratio its end drives the drill d. Part 1 is rigidly connected to the handle, which is not shown here.
