Description
Schraubenschlüssel. Zusatz zum Patent 353T26. Gemäß vorliegender Zusatzerfindung ist der den Gegenstand des Hauptpatentes bildende Schraubenschlüssel in der Richtung verbessert, daß die untere, zweckmäßig aufgerauhte Fläche der beweglichen Klemmbacke in der Längsrichtung derart abgeschrägt ist, daß sie mit dei entsprechend abgeschrägten oberen Fläche des Druckstücks keilartig zusammenwirkt und die bewegliche Klemmbacke sich infolgedessen bei einer unbeabsichtigten Offnungsbewegung zwischen der festen Klemmbacke und dem Druckstück selbsttätig festkeilt.Wrench. Addendum to patent 353T26. According to the present additional invention is the wrench in the direction that forms the subject of the main patent improved that the lower, appropriately roughened surface of the movable clamping jaw is beveled in the longitudinal direction such that it is beveled accordingly with the dei upper surface of the pressure piece cooperates like a wedge and the movable clamping jaw as a result, in the event of an unintended opening movement between the fixed Clamping jaw and the pressure piece automatically wedged.
Auf der beiliegenden Zeichnung ist die neue Ausführungsform, der Erfindung beispielsweise dargestellt, und zwar zeigt Abb. T einen Längsschnitt und Abb. a einen Querschnitt.On the accompanying drawing is the new embodiment of the invention shown for example, namely Fig. T shows a longitudinal section and Fig. a a cross section.
Die Bauart des Schraubenschlüssels ist die gleiche wie nach dem Hauptpatent. Die untere, zweckmäßig aufgerauhte Fläche der beweglichen Klemmbacke c ist jedoch in der Längsrichtung derart abgeschrägt, daß sie mit der entsprechend abgeschrägten oberen Fläche des Druckstücks ,in keilartig zusammenwirkt und die bewegliche Klemmbacke sich infolgedessen bei einer unbeabsichtigten Offnungsbewegung zwischen der festen Klemmbacke a und dem Druckstück m selbsttätig festkeilt. Es ist infolgedessen bei dieser Ausführungsform der Erfindung vollkommen ausgeschlossen, daß die bewegliche Klemmbacke während der Handhabung des Schraubenschlüssels ihre Sperrlage irgendwie ändert.The design of the wrench is the same as according to the main patent. The lower, appropriately roughened surface of the movable jaw c is, however beveled in the longitudinal direction in such a way that they are tapered with the correspondingly upper surface of the pressure piece, cooperates in a wedge-like manner and the movable clamping jaw as a result, in the event of an unintended opening movement between the fixed Clamping jaw a and the pressure piece m automatically wedged. As a result, it is at this embodiment of the invention completely excluded that the movable Jaw somehow lock position while handling the wrench changes.
