Description

BESCHREIBUNGDESCRIPTION

Herkömmliche Schrauben müssen bei Verbindungen von Werkstücken mit glatter Oberfläche am Schraubenkopf (1) festgehalten werden, um das Mitdrehen der Schraube beim Festziehen der Mutter zu verhindern.When connecting workpieces with a smooth surface, conventional screws must be held at the screw head (1) to prevent the screw from turning when the nut is tightened.

Wenn die Verbindungsstelle ungünstig liegt, werden zwei Personen zum Festziehen der Schraube benötigt.If the connection point is in an unfavorable position, two people are required to tighten the screw.

Dieses Problem wird bei Verwendung der im Schutzanspruch beschriebenen Schraube gelöst. Durch Einschlagen des Dornes (2) in das Werkstück, verkeilt sich die Schraube und sitzt fest. Die Schraube kann mit nur einer Hand festgezogen werden. Ein Schlitz, Kreuzschlitz, o.a. im Schraubenkopf (1) wird nicht mehr benötigt.This problem is solved by using the screw described in the protection claim. By driving the mandrel (2) into the workpiece, the screw wedges itself and sits firmly. The screw can be tightened with just one hand. A slot, Phillips, or similar in the screw head (1) is no longer required.

Der Vorteil dieser Erfindung besteht im geringeren Arbeitsaufwand bei der Montage von Werkstücken.The advantage of this invention is the reduced workload when assembling workpieces.

Müssen zum Beispiel zwei Schrankwände mit glatter Oberfläche miteinander verbunden werden, bleibt dem Monteur nach dem Einschlagen des Dornes (2) noch die Möglichkeit mit einer Hand die Wände in der richtigen Lage zu halten. Mit der anderen Hand kann er die Schraube festziehen. If, for example, two cupboard walls with a smooth surface need to be connected together, the fitter can still hold the walls in the correct position with one hand after driving in the mandrel (2). He can tighten the screw with the other hand.
