Sicherung gegen unbefugtes Verstellen einer Einstellschraube eines VergasersProtection against unauthorized adjustment of an adjusting screw of a carburetor

Die Erfindung betrifft eine Sicherung gegen unbefugtes Verstellen einer Einstellschraube eines Vergasers mittels einer Kunststoffkappe, die über den Kopf der Schraube gedrückt ist und mit einer Lippe in eine Nut des Schraubenkopfes eingreift.The invention relates to a safeguard against unauthorized adjustment of an adjusting screw of a carburetor by means of a plastic cap that is pressed over the head of the screw and with a lip in a groove of the screw head engages.

Derartige Sicherungen haben den Zweck, unbefugte Eingriffe, die die Abgaszusammensetzung beeinflussen, deutlich sichtbar zu machen, da diese Eingriffe in Zukunft nur noch von Werkstätten mit Abgasmessgerä'ten vorgenommen werden dürfen·The purpose of such safeguards is to prevent unauthorized interventions that affect the composition of the exhaust gas, to make it clearly visible, since in the future these interventions will only be carried out by workshops with exhaust gas measuring devices may be

Derartige Sicherungen sind bereits bekannt (s. US-PS 3 6lÖ 906 und DT-OS 2 401 803). Die Sicherung entsprechend der US-PS hat den Nachteil, dass die Schraube sich während des Aufbringens der Kappe verstellen kann» Ein Nachteil der Sicherungen entsprechend den beiden obigen Patentschriften liegt darin, dass es möglich ist, die Kunststoffkappe abzunehmen und wieder aufzusetzen, ohne sie dabei zu zerstören, solange wie der Kunststoff, aus dem die Kappe besteht, derartige Manipulationen zulä'sst, das heisst solange 709822/042»Such fuses are already known (see US-PS 3 6lÖ 906 and DT-OS 2 401 803). The fuse accordingly the US-PS has the disadvantage that the screw can be adjusted while the cap is being attached »A disadvantage of the Fuses according to the two above patents is that it is possible to remove the plastic cap and put it back on without destroying it, as long as the plastic from which the cap is made allows such manipulations, that is as long as 709822/042 »

diese Kunststoffkappe nicht brüchig geworden ist.this plastic cap has not become brittle.

Der Erfindung liegt die Aifgabe zugrunde, eine Sicherung zu schaffen, die einen unbefugten Eingriff dadurch kenntlich macht, dass sie bei diesem zerstört wird.The invention is based on the task of a fuse to create that makes an unauthorized intervention recognizable by the fact that it is destroyed in this.

Diese Aufgabe wird erfindungsgemäss dadurch gelost, dass die Kappe aus zwei konzentrisch zueinander angeordneten, über einen Boden miteinander verbundenen Ringen besteht, wovon der innere Ring mit einer Lippe versehen ist, und dass im Boden zwischen den Ringen eine Vielzahl von Sollbruchstellen angeordnet ist» Vorzugsweise besteht die Lip^e aus mehreren peripherisch angeordneten Nasen.This object is achieved according to the invention in that the cap consists of two concentrically arranged, There are rings connected to one another via a base, of which the inner ring has a lip is provided, and that a plurality of predetermined breaking points is arranged in the ground between the rings »Preferably the lip consists of several peripherally arranged noses.

Ein Ausfuhrungsbeispiel der Erfindung ist in der Zeichnung schematisch dargestellt und wird im folgenden näher beschrieben.An exemplary embodiment of the invention is shown schematically in the drawing and is described below described in more detail.

In Figur 1 ist in schematischem Schnitt eine erfindungsgemässe Sicherung dargestellt.In Figure 1 is a schematic section according to the invention Fuse shown.

Figur 2 ist eine Draufsicht auf die Kappe der Sicherung nach Figur 1.FIG. 2 is a plan view of the cap of the fuse of FIG.

Als Beispiel fur die Anwendung der erfindungsgemässen Kappe 1 ist hier eine in einem Hebel 2 angeordnete Einstellschraube 3 gewählt worden. Die Schraube ist in eine selbstsichernde Gewindebuchse 4 eingeschraubt. Die Kappe 1 greift mittels einer aus mehreren Nasen 5 bestehenden Lippe des inneren Riges 6 in dieAs an example of the use of the cap 1 according to the invention, one arranged in a lever 2 is shown here Adjustment screw 3 has been selected. The screw is screwed into a self-locking threaded bushing 4. The cap 1 engages by means of a lip of the inner rim 6 consisting of several lugs 5

Nut 7 der Schraube 3 ein. Konzentrisch zu dem Ring 6 709822/0429Groove 7 of screw 3. Concentric to ring 6 709822/0429

ist der ä'ussere Ring Ö angeordnet. Der Abstand zwischen den Ringen 6, Ö ist so gross, dass der Ring Ö nicht soweit zusammengedruckt werden kann, dass eine kraftschlüssige Verbindung zwischen dem inneren Ring 6 und der Schraube 3 zur Verstellung derselben entsteht. Bei dem Versuch, den Ring Ö derart zusammenzudrucken, wird das spröde Kunststoffmaterial der Kappe 1 im Boden 9 an einer Vielzahl von zwischen den Ringen 6, Ö angeordneten Sollbruchstellen 10 brechen} sodass der unbefugte Eingriff kenntlich wird. Dasselbe gilt, wenn versucht wird, die Kappe mit einem Werkzeug abzunehmen.the outer ring Ö is arranged. The distance between the rings 6, Ö is so large that the ring Ö cannot be compressed to such an extent that a non-positive connection between the inner ring 6 and the screw 3 for adjusting the same is created. In an attempt zusammenzudrucken the ring east so the brittle plastic material of the cap 1 in the bottom 9 is arranged at a plurality of between the rings 6, Ö predetermined breaking points break 10} so that the tampering is marked. The same is true when trying to remove the cap with a tool.

Die Kappe kann entsprechend DT-OS (P 25 48 226.2 vom 28.Oktober 1975) hergestellt werden.The cap can be manufactured according to DT-OS (P 25 48 226.2 of October 28, 1975).
