Description

Sicherung gegen unbefugtes Lösen von Sperrmitteln, insbesondere von Schrauben, Muttern od. dgl. Oft wird von Unbefugten versucht, Sperrungen, .die durch Schraubent, Muttern od. @dgl. herbeigeführt werden, mittels Schraubenzieher, Schraubenschlüssel od.,dgl. zu lösen, um an die abgesperrten Gegenstände heranzukommen.Securing against unauthorized loosening of locking devices, in particular of Screws, nuts or the like. Often unauthorized persons attempt to block, .the Screws, nuts or the like. be brought about by means of a screwdriver, wrench od., like. to solve to get to the locked objects.

Die Erfindung hat zum Zweck, Schrauben, Muttern o,d.,dgl. derart auszubilden, daß gewöhnliche Werkzeuge von ,ihnen abgleiten, so daß sie nicht mit diesen .gelöst werden können, sondern nur mit Spezialvorrichtungen, die eigens auf die bestimmten Befestigungsmittel abgestimmt sind.The invention has for the purpose of screws, nuts o, d., Like. to train in such a way that ordinary tools slip off of them, so that they do not come loose with them can be, but only with special devices that are specially designed for the specific Fasteners are matched.

Gemäß der Erfindung wird die Oberfläche der Schrauben, Muttern o.d.,dgl.; .die in eingeschraubtem Zustand von außen zugän.glieh ist, derart ausgebildet, daß ihr Querschnitt gegen ihre Achse genügend geneigt ist, um das Lösen mittels der gewöhnlichen Werkzeuge, wie Zangen, Schraubenzieher od.:dgl., zu verhindern oder mindestens wesentlich zu erschweren. Es hat sich gezeigt, @da.ß eine Neigung ,des Querschnitts der Oberfläche von mehr als 30° gegen die Achse dafür gewöhnlich ausreichend ist. Die Schraube, Mutter od. ,dgl. wird außerdem mit im wesentlichen in Achsrichtung verlaufenden Öffnungen versehen, die zur Aufnahme der zur Lösung vorgesehenen Spezialwerkzeuge dienen.According to the invention, the surface of the screws, nuts or the like; . Which is accessible from the outside when screwed in, designed such that its cross-section is inclined enough against its axis to allow the loosening by means of the Ordinary tools, such as pliers, screwdrivers or the like, to prevent or at least to make it much more difficult. It has been shown that there is a tendency to des Cross-section of the surface of more than 30 ° against the axis is usually sufficient for this is. The screw, nut or the like. is also essentially in the axial direction running openings provided to accommodate the special tools provided for the solution to serve.

In der Zeichnung sind einige Ausführungsbeispiele angegeben: Fig. i zeigt eine Schraube i mit einem Kopf 2, der eine konvexe Oberfläche von der Form eines Kugelabschnitts hat. In . die Oberfläche sind Löcher 3 eingelassen, zu denen Stifte 4 eines Schlüssels oder Zwischenschlüssels 5 - (Fig. 2) passen. Der Zwischenschlüssel hat eine Höhlung 6, die dem konvexen Kopf 2 entspricht und in die die Stifte 4 hineinragen. Außen kann ,der Zwischenschlüssel z. B als Viex{kant oder Sechskant ausgebildet sein, oder man kanny wie in Fig. 2 dar-. ,gestellt, einen besonderen Angriffskopf 7 für den Vierkant ibzw. Sechskant vorsehen.Some exemplary embodiments are indicated in the drawing: i shows a screw i with a head 2 that has a convex surface of the shape one Has spherical section. In . holes 3 are embedded in the surface, to which pins 4 of a key or intermediate key 5 - (Fig. 2) fit. The intermediate key has a cavity 6 which corresponds to the convex head 2 and into which the pins 4 protrude. Outside can, the intermediate key z. B as Viex {kant or hexagon, or you can dar- as in Fig. 2. , posed, one special attack head 7 for the square ibzw. Provide hexagon.

In Fig. 3 ist der gleiche Kopf gezeigt, jedoch ist er hier in der Oberfläche des der Sicherung dienen-.den Gegenstandes versenkt.The same head is shown in FIG. 3, but here it is in FIG Surface of the fuse-. The object is sunk.

Man kann ,die Oberfläche der Schraube, Mutter od. @dgl. auch konkav ausbilden, `wie es in Fig. 4 oder 5 .dargestellt ist. Einen passenden Zwischenschlüssel dafür zeigt Fig. 6, .bei dem die Stifte 8 aus der entsprechend dem konkaven Kopf geformten konvexen Oberfläche heraustreten.You can, the surface of the screw, nut or the like. also concave, as shown in Fig. 4 or 5. A suitable intermediate key for this is shown in FIG. 6, in which the pins 8 protrude from the convex surface which is shaped in accordance with the concave head.

Fig. 7 zeigt eine Oberfläche .der Schraube, die teils konkav; teils konvex geformt ist und zu der ebenfalls ein Schlüssel nach Art der Fig. 6 paßt.Fig. 7 shows a surface of the screw, which is partly concave; part Is convex in shape and to which a key like the one in FIG. 6 also fits.

In Fig. 8 ist eine versenkte Schraube dargestellt, deren Senköffnung einen mit Rändelung 9 versehenen Rand .'hat. Wenn ein Unibefugter versuchen sollte, diese Schraube durch Ansetzen eines meißelartigen Gegenstandes am Sehrawbenrand durch Hammerschläge zu öffnen, so wird das durch .den Meißel deformierte Material des Schraubenkopfes in ,die Rändelung der Senköffnung hineingetrieben und verklemmt Iden Schraubenkopf, so, daß er noch: schwieriger :durch den Unbefugten lösbar wird.In Fig. 8 a countersunk screw is shown, the countersunk opening has an edge provided with knurling 9. If an unauthorized person should try this screw by attaching a chisel-like object to the margin of the veil opened by hammer blows, the material deformed by the chisel becomes of the screw head in, the knurling of the countersunk opening driven in and jammed I the screw head in such a way that it is even: more difficult: detachable by the unauthorized person.

Diie Schraubenköpfe kann man: konkw oder konvex oder konkav-konvex halbkugelig, linsenförmig oder mit einer sonst geeigneten.Fläche ausbilden.The screw heads can be: concave or convex or concave-convex hemispherical, lenticular or with another suitable surface.

Ebenso wie Schrauben können auch Gewindemuttern in ,der beschriebenen Weise ausgebildet werden.As well as screws, threaded nuts can also be used in that described Way to be trained.

Um zu verhindern, daß ein Zwischenschlüssel leicht als Nachschlüssel benutzt werden kann, ist es zweckmäßig, die Verteilung ,der Stifte 4 bzw. 8 ,auf dem Umfang unregelmäßig vorzunehmen und ,die Anzahl der Stifte ebenfalls so zu variieren, daß bestimmte Zwischenschlüssel immer nur zu bestimmten Schrauben bzw. Müttern passen, wie es z. B. in Fig. 9 dargestellt ist. Außerdem kann man auch noch die Stifte bzw. Löcher in verschiedenem Abstand vom Mittelpunkt anordnen.To prevent an intermediate key from being easily used as a duplicate key can be used, it is appropriate to the distribution, the pins 4 and 8, on to make the scope irregularly and to vary the number of pens in such a way as to that certain intermediate keys only ever fit certain screws or nuts, how it z. B. is shown in FIG. You can also use the pens or Arrange holes at different distances from the center.

Weiterhin kann man (die Länge und die Durchmesser der Stifte variieren, so. daß man durch diese verschiedenen Variationsmöglichkeiten eine schier unerschöpfliche Anzahl von Möglichkeiten. für die Löcher .und Stifte erhält, die es erlauben, praktisch für jeden Verwendungsfall eine andere Anordnung zu schaffen, die nur fürdiesen und sonst für keinen .anderen Verwendungsfall p.aßtund.deshalb in jedem Einzelfall die Sicherheit gilbt, daß ,die Verschraubung von einem Unbefugten nicht leicht geöffnet werden kann.Furthermore you can (vary the length and the diameter of the pins, so. that through these different possibilities of variation one can get an almost inexhaustible one Number of possibilities. for the holes .and pins that allow it to be practical to create a different arrangement for each application, which is only for this and otherwise it is not suitable for any other application and therefore in each individual case the It is safe to say that the screw connection is not easily opened by an unauthorized person can be.
