Description
Zahnärztliches Winkelstück Die Erfindung betrifft ein zahnärztliches Winkelstück mit einem an der Rückseite des Winkelkopfes vorgesehenen und unter Federwirkung stehenden Schieber zum. Sichern der Fräs-, Bohr- oder Schleifwerkzeuge gegen Axialverschiebung und besteht darin, daß die sich im wesentlichen quer zur Bewegungsrichtung des Schiebers erstreckende Schraubenfeder mit ihrem einen Ende an dem Halsstück des Winkelstückkopfes - abgestützt ist, während ihr anderes Ende derart am Schieber angreift, daß die Feder in beiden Endstellungen des Schiebers im wesentlichen entspannt ist, während sie bei seiner Bewegung von einer Endlage in die andere vorübergehend zusammengedrückt wird und so als Schnäpper wirkt und den Schieber in beiden-Endstellungen zu halten bestrebt ist.Dental contra-angle The invention relates to a dental Elbow with a provided on the back of the angle head and under spring action standing slide for. Securing the milling, drilling or grinding tools against axial displacement and consists in that the is essentially transverse to the direction of movement of the slide extending coil spring with its one end on the neck piece of the elbow head - Is supported, while its other end engages the slide in such a way that the The spring is essentially relaxed in both end positions of the slide, while they are temporarily compressed as it moves from one end position to the other and so acts as a catch and to hold the slide in both end positions is striving.
Auf der Zeichnung ist der Erfindungsgegenstand in einer Ausführungsform dargestellt.The subject of the invention is shown in one embodiment in the drawing shown.
Während bei den bekannten Winkelstücken dieser Art die den Schieber in der .Schließlage haltende Feder parallel zum Schieber angeordnet .ist und diesen nur in seiner Schließlage hält, so daß der Schieber beim Einsetzen des Bohrers gegen die Wirkung der Feder dauernd unter Druck gehalten werden muß, ist gemäß der Erfindung die Feder f als Schnäpper ausgebildet und liegt mit ihrer Achse im wesentlichen senkrecht zum Schieber c. Ihr eines Ende ist gegen die Wandung la der Handstückhülse abgestützt, während ihr anderes Ende zweckmäßigerweise mit einer Roller o. dgl. versehen ist, die in einer Nut bzw. Niesche n des Schiebers c geführt ist Durch Druck auf die Fläche u des Schiebers c wird die Roller mitgenommen und die-Feder fein wenig zusammengedrückt, um sodann .in der anderen Endlage des Schiebers c wieder entspannt zu werden, wobei sich die Rolle r in die entgegengesetzte Ecke der Niesche n legt. Man kann dann den Schieber c loslassen, ohne daß er wieder zurückfällt, wie es bei den bekannten Vorrichtungen der Fall ist.While with the known contra-angle handpieces of this type, the slide In the closed position holding spring is arranged parallel to the slide and this only holds in its closed position, so that the slide against when inserting the drill the action of the spring must be kept permanently under pressure, is according to the invention the spring f is designed as a catch and is essentially located with its axis perpendicular to the slide c. One end of it is against the wall la of the handpiece sleeve supported, while its other end expediently with a roller or the like. is provided, which is guided in a groove or niche n of the slide c Pressure on the surface u of the slide c is taken along with the roller and the spring finely compressed a little to then .in the other end position of the slide c again to be relaxed, with the roller r in the opposite corner of the niche n lays. You can then let go of the slide c without it falling back again, as is the case with the known devices.
