die Anlageflächelieh. Hiezu wird der ausgebauchte Mittelteil des Sichenmgsstiftss wieder hineingedrückt, z. B. mittels einer Zange, wodurch das obere Ende 7b sich automatisch ausschiebt und leicht mit der Zange gefasst werden kann.
Die Fig. 4 und 5 zeigen ein Ausführungsbeispiel mit Beilagscheibe, die kein Hindernis für die Anwendbarkeit der Sicherung bildet. Der Schraubnkopf l unterscheidet sich von der früheren Ausführung

6a..lagscheibe 10 dadurch übernommen, dass letztere mit einem Loch 11 vom Durchmesser der Bohrung 2 ve sehen ist. Fig. 6 zeigt die Schraube gemäss Fig. 4 im Grundriss.
In Fig. 7 ist eine mit der Sicherung ausgestattete Schraubenmutter in Draufsicht zu sehen.
Die Fig. 8-10 zeigen eine besonders vorteilhafte Ausgestaltung des Eindringendes 7a des Sicherungs- stiftes 7. Danach läuft dieses Stiftende keilförmig in eine gerade Schneide 12 aus. Fig. 8 zeigt die schmale und Fig. 9 die breite Seite des Keiles.

darin gelegen, dass keinerlei Drehbewegung des Sicherungsstiftes stattfinden kann.
PATENTANSPRÜCHE :
1. Schraubensicherung, bestehend aus einem Sicherungsstift, der den Kopf einer Schraube bzw. eines Schraubenbolzens oder einer Mutter axial durchsetzt und mit seinem zugeschärften Ende in das die An- 1agef1äche bildende Werkstück eindringt, dadurch gekennzeichnet, dass der die Bohrung durchsetzende Sicherungsstift glatt (gewindelos) ist und im Schraubenkopf (1) bzw. in der Schraubenmutter eine sich nur über den mittleren Teil der Höhe des-bzw. derselben erstreckende Ausnehmung (4) vorgesehen ist, die mindestens bis zur Symmetrieebene der Bohrung (2) reicht, derart, dass die Bohrung im mittleren Teil gegen die Ausnehmung zu als Rinne offen liegt.

the contact surface. For this purpose, the bulged middle part of the Sichenmgsstiftss is pushed back in, z. B. by means of pliers, whereby the upper end 7b automatically pushes out and can easily be grasped with the pliers.
4 and 5 show an embodiment with a washer, which does not constitute an obstacle to the applicability of the fuse. The screw head l differs from the previous version
EMI2.2
6a..lagscheibe 10 taken over by the fact that the latter is seen with a hole 11 from the diameter of the hole 2 ve. FIG. 6 shows the screw according to FIG. 4 in plan.
In Fig. 7, a screw nut equipped with the lock can be seen in plan view.
FIGS. 8-10 show a particularly advantageous embodiment of the penetrating end 7a of the locking pin 7. This pin end then runs out in a wedge shape into a straight cutting edge 12. Fig. 8 shows the narrow and Fig. 9 the broad side of the wedge.
EMI2.3
located in the fact that no rotational movement of the locking pin can take place.
PATENT CLAIMS:
1. Screw locking, consisting of a locking pin which axially penetrates the head of a screw or a screw bolt or a nut and penetrates with its sharpened end into the workpiece forming the contact surface, characterized in that the locking pin penetrating the bore is smooth (threadless ) is and in the screw head (1) or in the screw nut a only over the middle part of the height of the or. the same extending recess (4) is provided, which extends at least up to the plane of symmetry of the bore (2), such that the bore is open in the middle part towards the recess as a channel.
