Schlitzschraube für FestverbindungSlotted screw for permanent connection

BE-SCHREIBUNGDESCRIPTION

Zweck dieser Ausführung ist,zu verhindern, dass Schlitzschraubenverbindungen von Unbefugten mit dem Schraubenzieher gelöst werden können. Besonders ist hierbei an Einrichtung^** in Verkehrsmitteln, Hotels usw. gedacht. Auch im technischen Senior gibt es Schraubverbindungen, wo man vom Hersteller nicht wünscht, dass sie von Nichtfachleuten geöffnet werden können.The purpose of this design is to prevent slotted screw connections can be loosened by unauthorized persons with a screwdriver. A particular feature of this is facility ^ ** in means of transport, Hotels etc. thought. There are also screw connections in the technical senior, where the manufacturer does not want them to be able to be opened by non-specialists.

In der Bauform unterscheidet sich die Neuheit von den bisher bekannten Schlitzschrauben dadurch, dass nur die Kopfform (l) für die Rechtsdrehung vorhanden ist. Der übergang von der flachen Fläche (2) zur vorhandenen Kopfform ist eine Rundung (3)· Dadurch wird bei gewollter Linksdrehung der Schraubenzieher aus der Schraube herausgehoben und eine übertragung des Drehmoments auf die Schraube ist nicht möglich.In terms of design, the novelty differs from the previously known Slotted screws in that only the head shape (l) is available for clockwise rotation. The transition from the flat surface (2) There is a rounding (3) for the existing head shape intentional counter-clockwise rotation of the screwdriver is lifted out of the screw and the torque is transferred to the screw not possible.

Sollten die sogenannten Festverbindungen doch einmal gelöst werden müssen, so kann das Lösen der Schraube mit Kreuzmeißel und Hammer erfolgen.Should the so-called fixed connections be solved the screw can be loosened with a cross chisel and hammer.
