Description

Schraubensicherung. Die vorliegende Erfindung betrifft eine weitere Ausbildung der in der Patentschrift 422133 beschriebenen Schraubensicherung. Der Zweck der Erfindung besteht darin, eine insbesondere für kleine Kopfschrauben geeignete Sicherung zu schaffen. Dies wird gemäß der Erfindung dadurch erreicht, daß ein vollständig in die Unterlage eingesetzter Metallstreifen oder Draht an einem unterhalb des Schraubenkopfes angeordneten, mit Zähnen versehenen und vollständig in die Unterlage eingelassenen Bund angreift. Zweckmäßig ist die Bohrung der Unterlage, die den Bund umgibt, so bemessen, daß der Metallstreifen in an sich bekannter Weise mit Hilfe eines durch eine Öffnung der Unterlage eingeführten Werkzeugs aus den Zähnen des Bundes herausgehoben werden kann, damit man die Schraube lösen kann.Screw locking. The present invention relates to another Formation of the screw locking device described in patent specification 422133. Of the The purpose of the invention is to provide a particularly suitable for small head screws To create backup. This is achieved according to the invention in that a completely Metal strips or wire inserted into the base on one below the screw head arranged, provided with teeth and completely embedded in the base Bund attacks. Appropriately, the hole in the pad that surrounds the collar, so dimensioned that the metal strip in a known manner with the help of a an opening of the pad inserted tool lifted out of the teeth of the federal government can be so that you can loosen the screw.

Auf der Zeichnung ist der Gegenstand der Erfindung in einem Ausführungsbeispiel dargestellt.In the drawing, the subject of the invention is in one embodiment shown.

Abb. t ist ein senkrechter Längsschnitt durch die Sicherung, wobei die Schraube in Ansicht gezeichnet ist.Fig. T is a vertical longitudinal section through the fuse, wherein the screw is drawn in view.

Abb.2 ist ein wagerechter Schnitt nach der Linie A-B in Abb. 1.Fig.2 is a horizontal section along the line A-B in Fig. 1.

Unterhalb des Kopfes a der Schraube ist ein mit Zähnen versehener Bund b angeordnet. Der Bund wird von einer Bohrung c der Unterlage d vollständig aufgenommen. In einen Schlitz der Unterlage ist ein Blechstreifen oder ein Drahte eingesetzt, der mit dem Bund b ein Kniehebelpaar bildet. Der Blechstreifen oder Drahte reicht zweckmäßig nicht bis zum Grund der Bohrung c. Eine in der Unterlage d angeordnete Öffnung f gestattet, in an sich bekannter Weise ein Werkzeug, z. B. einen mit hakenförmigem Ende versehenen Draht, in die Bohrung c einzuführen und den Blechstreifen e aus den Zähnen des Bundes b herauszuheben, wenn man die Schraube lösen will. Das hakenförmige Ende läßt sich deshalb mit dem Blechstreifen e in Eingriff bringen, weil letzterer nicht bis zum Boden der Bohrung c reicht.A toothed collar b is arranged below the head a of the screw. The collar is completely absorbed by a hole c in the base d. A sheet metal strip or a wire is inserted into a slot in the base and forms a pair of toggle levers with the collar b. The sheet metal strip or wire expediently does not extend to the bottom of the hole c. An opening f arranged in the base d allows a tool, e.g. B. a wire provided with a hook-shaped end to insert into the hole c and lift the sheet metal strip e out of the teeth of the federal government b if you want to loosen the screw. The hook-shaped end can therefore be brought into engagement with the sheet metal strip e because the latter does not extend to the bottom of the bore c.

Wie die Abb. i erkennen läßt, sind die Zähne b nach unten hin am besten verjüngt. Bei dem Eindrehen der Schraube gelangen die Zähne b in Eingriff mit dem Blechstreifen e. Letzterer verhindert ein Zurückdrehen der.angezogenen Schraube.As Fig. I shows, teeth b are best downwards rejuvenates. When the screw is screwed in, the teeth b come into engagement with the Sheet metal strips e. The latter prevents the tightened screw from turning back.
