Description
Schraubenschlüssel Gegenstand der Erfindung ist ein Schraubenschlüssel zum Anziehen und Lösen von Schrauben, Muttern o. dgl.Wrench The invention relates to a wrench for tightening and loosening screws, nuts or the like.
Bei den bisher bekannten Schraubenschlüsseln ist das Schlüsselmaul derart ausgebildet, daß die Maulecken genau mit den Ecken der zu fassenden Mutter übereinstimmen. Das hat zur 'Folge, daß die Ecken der Mutter oder des Schraubenkopfes sich in der Drehrichtung abnutzen und einen Grat -absetzen. Nach öfterem Drehen werden daher die Ecken derart deformiert. daß der Schlüssel nicht mehr richtig faßt und über die Ecken abrutscht. Der sich durch die Deformation der Ecken bildende Grat führt andererseits dazu, daß der Schlüssel nicht mehr paßt, so daß die Mutter durch eine neue ersetzt werden muß. Gemäß der Erfindung kennzeichnet sich der Schraubenschlüssel nun darin, daß sämtliche Ecken des Schlüsselmaules ,außerhalb der Ecken der Mutter 'sind, so daß diese nur ,außerhalb ihrer Ecken vom Schlüsselmaul erfaßt wird. Die den bisher bekannten Schraubenschlüsseln anhaftenden Mängel sind durch die erfindungsgemäße Ausbildung des Schlüsselmaules beseitigt. Da ,auf die Ecken der Mutter beim Anziehen -oder Lösen kein Druck ausgeübt wird, werden :diese nicht deformiert und sind daher lange gebrauchsfähig. Da sich auch an den Mutterecken kein Grad bilden kann, pa.ßt der Schraubenschlüssel stets.In the previously known wrenches, the keyhole is designed so that the corners of the mouth exactly with the corners of the nut to be grasped to match. This has the consequence that the corners of the nut or the screw head wear out in the direction of rotation and remove a burr. After turning it several times therefore, the corners are so deformed. that the key is no longer right and slips over the corners. The one formed by the deformation of the corners Burr on the other hand leads to the fact that the key no longer fits, so that the nut must be replaced by a new one. According to the invention, the wrench is characterized now in that all the corners of the keyhole outside the corners of the mother 'so that it is only grasped by the keyhole outside its corners. the the previously known wrenches adhering shortcomings are due to the invention Eliminated training of the key mouth. There, on the corners of the nut when tightening -or releasing no pressure: these are not deformed and are therefore usable for a long time. Since no degree can form at the mother corners either, it is okay the wrench always.
In der Zeichnung ist der Gegenstand der Erfindung beispielsweise dargestellt.In the drawing, the subject matter of the invention is shown for example.
Der Schraubenschlüssel besteht aus dem Maul.- und dem Schaft b; die Mutter ist mit c bezeichnet. An der inneren Seite des Schlüsselmaules befinden sich die Ecken d, e, f und ö. Die Ecken der Mutter sind mit lt, i, h und Z bezeichnet. Die Ecken d, e, f und g des Schlüsselmaules befinden sich außerhalb der Ecken der Mutter, was dadurch erreicht ist, daß an den bisherigen, mit den Ecken der Mutter genau übereinstimmenden Maulecken kein Material vorhanden ist.The wrench consists of the Maul.- and the shaft b; the mother is marked with c. The corners d, e, f and ö are located on the inner side of the keyhole. The corners of the nut are labeled lt, i, h and Z. The corners d, e, f and g of the wrench mouth are located outside the corners of the nut, which is achieved by the fact that there is no material at the previous corners of the mouth that exactly matched the corners of the nut.
