Description

Um bei Stellschrauben mit unrundem Kopf einerseits ein selbsttätiges Verdrehen zu verhindern, anderseits ein leichtes Nachstellen mittels Schraubenziehers oder Schraubenschlüsseis zu erhalten, wird gemäß vorliegender Erfindung, die auf der Zeichnung in Abb. ι in Seitenansicht, in Abb. 2 im Grundriß, in Abb. 3 in Vorderansicht und in Abb. 4 in einer abgeänderten Ausführungsform dargestellt ist, als Sicherung eine Blattfeder α verwendet, die an ihrem einen Ende b an der Mutter c befestigt ist, während sie an ihrem anderen Ende d, an dem die zu sichernde Schraube e die Feder α durchsetzt, zu beiden Seiten in der Breite der Schlüsselweite niedrige, schräge, aufgebogene Lappen / besitzt, so daß der Schraubenkopf g zwischen den Lappen / sitzt und so gegen selbsttätiges Verdrehen gesichert ist. Beim Verstellen der Schraube e weicht das freie Federende rf nach unten aus, um bei der nächsten Stellung der Schrauben, bei der die Schlüsselweite wieder zwischen die aufgebogenen Lappen / paßt, wieder hochzufedern und die Schraube e zu sichern. Die in Abb. 4 dargestellte abgeänderte Ausführungsform weicht nur bezüglich der Form der Feder ax von der in den Abb. 1 bis 3 dargestellten Ausführungsform ab. In order to prevent automatic turning of adjusting screws with a non-round head, on the one hand, and to obtain easy readjustment by means of a screwdriver or wrench, on the other hand, according to the present invention, which is shown in the drawing in Fig. 3 is shown in a front view and in Fig. 4 in a modified embodiment, a leaf spring α used as a safety device, which is fastened at its one end b to the nut c , while at its other end d, on which the screw to be secured e the spring α penetrates, on both sides in the width of the wrench size low, inclined, bent up lobes / has, so that the screw head g between the lobes / sits and is thus secured against automatic rotation. When adjusting the screw e , the free end of the spring rf deviates downwards in order to spring up again in the next position of the screws, in which the wrench size fits between the bent tabs /, and to secure the screw e. The modified embodiment shown in Fig. 4 differs from the embodiment shown in Figs. 1 to 3 only with regard to the shape of the spring a x.
