Spannvorrichtung zur genauen Führung von HandkreissägenClamping device for precise guidance of hand-held circular saws Mit Hnndkreissägen, wie sie hauptsächlich als Helmworkiseuge gebräuchlich sind, kann auch eier geübt« Btunibzer kaum einen sauberen Schnitt erzielen.Diesem Nachteil kann auch ein Heimwerlcer-Sägetisch nioht entscheidend abhelfen, denn aus Kosten-und Platzg^ründen sind solche Sagetiaehe zu klein für größere Werkstücke.With circular saws, as they are mainly used as helmet workers are common, can hardly be practiced achieve a clean cut. This disadvantage can also be a Heimwerlcer saw table does not help decisively, because from For reasons of cost and space, such Sagetiaehe are too small for larger workpieces. Diesen Wachteilen soll die erflndungsgemäße Spannvorrichtung abhelfen. J?ig.1 zeigt als Beispiel eine einfache Ausführung. Das Werkstück 1 wird zwischen die hölzerne Unterlage 2 und den Vierkantstab aus Stahl 3 eingelegt. Zum leichten herausnehmen und einsetzen des Vierkantstabes zwischen die Halteschrauben 4 erhält dieser die beiden Schlitze 5, Ein durchsichtiges Zeiohendreieck 6 ist parallel zu seiner längsten Kante im Abstand a mit einem Strich versehen, milj/dessen Hilfe der zu sägende Schnitt genau in diesen Abstand von dem Vierkantstab zu bringen ist. Nun wird das Werkstück mit den Flügelmuttern der Schrauben 4 fest eingespannt, und die exakte Führung der Handkreissäge entlang dem Vierkantstab ergibt einen sauberen, geraden Schnitt.The tensioning device according to the invention is intended to address these disadvantages remedy. J? Ig.1 shows a simple design as an example. The workpiece 1 is between the wooden base 2 and the square bar made of steel 3 is inserted. For easy removal and insertion of the square bar between the retaining screws 4 this receives the two slots 5, a transparent one Numeral triangle 6 is provided with a line parallel to its longest edge at a distance a, milj / its help the cut to be sawed at exactly this distance from the square bar is to be brought. Now the workpiece is firmly clamped with the wing nuts of the screws 4, and the exact Guiding the circular saw along the square bar results in a clean, straight cut. Die zwei seitlich angebrachten Holzstäbe 7 sind so in den Schrauben 4 gehaltert, daß sie passend weit herrausklappbar sind und auch einer großen Werkstoffplatte beiderseits der Unterlage 2 eine ebene Auflage bieten. Bei großen Werkstücken ist dies nötig, um ein Abbrechen des abzutrnnenden Werkstückteils ku*z vor Vollendung des Sägeschnitts zu vermeiden. Damit lassen sich praktisch alle im Handel erhältlichen Plattengroßen genauso gut bearbeiten, wie mit großen im Gewerbe üblichen Tiechkreissägen.

The two laterally attached wooden rods 7 are held in the screws 4 in such a way that they can be folded out to a suitable extent and also provide a flat support for a large sheet of material on both sides of the base 2. In the case of large workpieces, this is necessary in order to prevent the workpiece part to be severed from breaking off before the saw cut has been completed. This means that practically all commercially available panel sizes can be processed just as well as with the large circular saws commonly used in the trade.
