Vorrichtung zum Sichern von Mehrkant-Kopfsehrauben gegen LösenDevice for securing polygonal head screws against loosening

Die Erfindung betrifft eine Vorrichtung zum Sichern von Mehrkant-Kopfsehrauben gegen Lösen, insbesondere für Einfüllöffnungen für hydraulische Bremsanlagen von Kraftfahrzeugen. The invention relates to a device for securing polygonal head screws against loosening, in particular for filling openings for hydraulic braking systems of motor vehicles.

Der Erfindung liegt die Aufgabe zugrunde, eine solche Vorrichtung derart zu gestalten, daß sie kostengünstig herstellbar und leicht montierbar ist, und daß sie sich mehrmals anwenden und entfernen läßt, ohne hierdurch ihre Betriebstüchtigkeit zu verlieren.The invention is based on the object of designing such a device in such a way that it can be manufactured inexpensively and is easy to assemble, and that it can be used and removed several times without thereby rendering it operational to lose.

Diese Aufgabe wird gemäß der Erfindung bei einer Vorrichtung der eingangs genannten Gattung dadurch gelöst, daß diese Vorrichtung aus plastischem Material besteht und eine Kappe aufweist, welche ihrerseits mit einem im wesentlichen kreisförmigen Sitz mit Mehrkantprofil ausgerüstet ist, und dieThis object is achieved according to the invention in a device of the type mentioned at the outset in that this Device made of plastic material and has a cap, which in turn with a substantially circular Seat is equipped with a polygonal profile, and the

Die Erfindung ist anhand der Zeichnung näher erläutert. Darin ist im einzelnen folgendes dargestellt:The invention is explained in more detail with reference to the drawing. The following is shown in detail:

Fig. 1 zeigt eine Ausführungsform der Erfindung in Draufsicht.Fig. 1 shows an embodiment of the invention in Top view.

Fig. 2 zeigt einen Teilschnitt des Gegenstandes von Fig. 1. Fig. 3 ist eine Frontansicht des Gegenstandes von Fig. 1.FIG. 2 shows a partial section of the object of FIG. 1. FIG. 3 is a front view of the object of FIG. 1.

Fig. 4 ist eine Schnittansieht einer zweiten Ausführungsform der Erfindung. Fig. 4 is a sectional view of a second embodiment of the invention.

Fig. 5 ist eine Frontansicht des Gegenstandes von Fig. 4.FIG. 5 is a front view of the article of FIG. 4.

Fig. β ist eine Teilschnittansicht des Gegenstandes von Fig. 4 in montiertem Zustand.Fig. Β is a partial sectional view of the article of Fig. 4 in the assembled state.

In den Figuren erkennt man eine Kappe 1 aus plastischem Material, die mit einem Sitz 2 von kreisförmiger Gestalt versehen ist, und dessen Innenprofil 3-polygonal ist, das jedoch auch eine Hirth-Verzahnung sein kann.A cap 1 made of plastic can be seen in the figures Material provided with a seat 2 of circular shape and the internal profile of which is 3-polygonal that however, it can also be a Hirth coupling.

Kappe 1 ist ferner mit einem Schaft 4 einteilig, der eine Versteifungsrippe 5 aufweist, und an desen anderem Ende eine Einrast-Biockiervorrichung vorgesehen ist. Diese besteht aus einer Art Pinzette (siehe Fig. 1, 2 und 3) oder einem Schnappeinsatz (siehe Fig. 4, 5 und 6).Cap 1 is also in one piece with a shaft 4, which has a stiffening rib 5, and at the other end thereof a latching device is provided. This exists from a kind of tweezers (see Fig. 1, 2 and 3) or a snap insert (see Fig. 4, 5 and 6).

In Fig. β ist die Montage einer zweiten Ausführungsform der Erfindung veranschaulicht. Hierbei ist die Kappe 1 über die Einfüllschraube 7 von polygonalem Profil einesIn Fig. Β the assembly of a second embodiment of the invention is illustrated. Here the cap is 1 over the filler screw 7 of a polygonal profile

Auf diese Weise vermag sich die Einfüllschraube 7 nicht zu lösen oder gelöst zu werden, ohne daß zuvor das gesamte erfindungsgemäße Teil abgenommen wird. In this way, the filler screw 7 cannot loosen or be loosened without first removing the entire part according to the invention.

Ist die einrastende Blockiereinrichtung nach Art einer Pinzette ausgeführt (siehe Fig. 1, 2 und J>), so kann sie an der Füll- oder Entleerleitung des Öles oder auf dem Rand eines Blechteiles befestigt sein.If the locking device that engages is designed like a pair of tweezers (see FIGS. 1, 2 and J>), it can be attached to the filling or draining line of the oil or to the edge of a sheet metal part.

Es versteht sich, daß die Gestalt der einrastenden Blockiereinrichtung 6, die Länge sowie das Profil des Schaftes 4 wie auch die Abmessungen der Kappe 1 willkürlich abgewandelt werden können, ohne daß dadurch der Rahmen der Erfindung verlassen wird.It is understood that the shape of the locking device 6, the length and the profile of the Shank 4 as well as the dimensions of the cap 1 can be arbitrarily modified without affecting the frame of the Invention is abandoned.
