Description
Winkelstück für zahnärztliche Fräs-, Bohr- und Schleifwerkzeuge. Winkelstücke, insbesondere solche für zahnärztliche Fräs-, Bohr- und Schleifwerkzeuge mit Schieber zur Sicherung des Werkzeuges, sind bekannt.Contra-angle handpiece for dental milling, drilling and grinding tools. Elbows, in particular those for dental milling, drilling and grinding tools with slide to secure the tool are known.
Gegenstand der vorliegenden Erfindung ist die Anordnung einer Feder, die den Schieber, der zweckmäßig mit einer schlitzförmigen, einen Ansatz tragenden Ausfräsung versehen ist, in die Sicherungsstellung drängt.The subject of the present invention is the arrangement of a spring, which the slide, which is expediently with a slot-shaped, an approach carrying Milling is provided, pushes into the locking position.
Die Zeichnung veranschaulicht den Erfindungsgegenstand, und zwar zeigt Abb. z die Gesamtansicht eines Winkelstückes gerader Bauart; jedoch läßt sich der Erfindungsgegenstand auch für sogenannte Kontra- (gebogene) Winkelstücke anwenden, Abb. 2 den Durchschnitt des den Schieber tragenden Kopfteiles in vergrößertem Maßstabe, Abb. 3 eine Seitenansicht gemäß Abb. 2, Abb. 4 einen Grundriß gemäß Abb. 3, Abb.5 ein Fräswerkzdug mit eingedrehter Ringnut.The drawing illustrates the subject matter of the invention, namely shows Fig. Z is the overall view of an angle piece of straight design; however, the The subject of the invention can also be used for so-called contra (curved) elbows, Fig. 2 shows the cross section of the head part carrying the slide on an enlarged scale, Fig. 3 is a side view according to Fig. 2, Fig. 4 is a plan according to Fig. 3, Fig.5 a milling tool with a screwed-in ring groove.
Im Kopf a (Abb. 2) führt sich schwalbenschwanzförmig ein Schieber c (Abb. 2, 3, 4), der mit einer schlitzförmigen, mit einem Ansatz d ausgestatteten Ausfräsung e versehen ist. Durch eine Feder f wird dieser Schieber c gegen einen Anschlag b gedrückt, so daß der mit dem Ansatz d versehene Teil der schlitzförmigen Ausfräsung e zentrisch zur Bohrung der Welle g sitzt. Soll das Fräs-, Bohr- oder Schleifwerkzeug eingesetzt werden, so genügt "ein Fingerdruck gegen den Schieber c (Abb. z), um diesen unter Gegendruck auf die Spiralfeder f gegen die Anschlagfläche h zu drücken (Abb. 2). Es stellt sich dann der untere Teil der schlitzförmigen Ausfräsung c zentrisch zur Bohrung der Welle g, so d.aß das Werkzeug eingeführt werden kann. Ein Nachlassen des Fingerdruckes läßt den Schieber c vermöge der Feder f mit seinem Ansatz d in. die Ringnut K (Abb. 5) des Werkzeuges einfallen. Das Werkzeug ist nun gegen Längsverschiebung gesichert, da ein unbeabsichtigtes Öffnen des Schiebers beim Gebrauch durch die ständige Federwirkung ausgeschlossen ist.In the head a (Fig. 2) there is a dovetail-shaped slide c (Fig. 2, 3, 4) which is provided with a slot-shaped cutout e equipped with a shoulder d. This slide c is pressed by a spring f against a stop b, so that the part of the slot-shaped cutout e provided with the projection d is centered on the bore of the shaft g. If the milling, drilling or grinding tool is to be used, all that is needed is a finger pressure against the slide c (Fig. Z) to press it against the stop surface h (Fig. 2) with counter pressure on the spiral spring f (Fig. 2) Then the lower part of the slot-shaped milled recess c centric to the bore of the shaft g, so that the tool can be inserted. A release of the finger pressure allows the slide c by means of the spring f with its extension d into the annular groove K (Fig. 5 The tool is now secured against longitudinal displacement, as unintentional opening of the slide during use is prevented by the constant spring action.
