Description

BeschreibungDescription

Es ist bekannt, daß metallene Rächen durch Umwelteinflüsse von Korrosion betroffen sind.An Automobilkarosserien werden so entstandene Durchrostungen sowie Spuren eines Unfalles mit der Folge einer Deformation der Karosserie in den häufigsten Fällen mit Polyestern, der sogenannten Spachtelmasse kaschiert. Diese Art der Vertuschung von Durchrostungen und Unfallschäden führt nicht nur zu Fehleinschätzungen des Wagenzustandes, sondern sie beinhaltet auch ein hohes Maß an Gefahr, wenn die Stabilität durch metallene Substanz nicht mehr gewährleistet ist.It is known that metal surfaces are affected by corrosion due to environmental influences. On car bodies, rust through and traces of an accident resulting in deformation of the body are most often covered up with polyester, the so-called filler. This type of covering up rust through and accident damage not only leads to misjudgments of the condition of the vehicle, but it also involves a high degree of danger if stability is no longer guaranteed by the metal substance.

Durch die Erfindung aus Ansprach 1 ist es für den Fachmann, sowohl für den Laien durch einfachste Anwendung möglich. Aussagen über den Zustand der gesammten Karosserie zu machen, ohne sich dabei von der Oberfläche täuschen zu lassen. Er kann feststellen, wo sich nicht direkt unter dem Lack metallener Untergrand befindet, sondern Polyesterspachtel, welcher eine Beule ausfüllt bzw. Rostlöcher bedeckt. Jegliche Abweichung des normalen Abstands zwischen metallenem Untergrand und lackierter Oberfläche läßt sich feststellen.The invention in claim 1 makes it possible for the expert and the layman to make statements about the condition of the entire body without being deceived by the surface. They can determine where there is not a metal base directly under the paint, but polyester filler, which fills a dent or covers rust holes. Any deviation from the normal distance between the metal base and the painted surface can be determined.

In den Figuren 1 und 2 ist das Kunststoffgehäuse 7 , welches im unteren Teil eine Öffnung besitzt dargestellt. Diese Öffnung erstreckt sich ins Innere des Gehäuses zylindrisch. In dieser zylindrischen Führung befindet sich ein Magnet 5 , welcher durch eine Stange 8 mit dem oberen Kontakt des Federkontaktschalters 4 verbunden ist. Oberhalb dieses Kontaktes befindet sich am Ende der Verbindungsstange 8 ein Kupplungselement 2 , welches verhindert, daß bei Drehung derFigures 1 and 2 show the plastic housing 7, which has an opening in the lower part. This opening extends cylindrically into the interior of the housing. In this cylindrical guide there is a magnet 5, which is connected to the upper contact of the spring contact switch 4 by a rod 8. Above this contact, at the end of the connecting rod 8, there is a coupling element 2, which prevents the

Eichschraube 3 die an ihr befindliche Feder 1 mitgedreht wird. Links und rechts neben der Gehäuseöffnung befindet sich ein Füzbelag 6. Bezeichnung 9 stellt in Fig.l einen "gesunden" Metallabschnitt z.B. aus einer Automobilkarosserie dar. In Fig.2 stellt Bezeichnung 9 einen deformierten Metallabschnitt dar, welcher mit Spachtelmasseauftrag versehen ist.Calibration screw 3 and the spring 1 attached to it are turned along with it. To the left and right of the housing opening there is a foot pad 6. In Fig.1, designation 9 represents a "healthy" metal section, e.g. from a car body. In Fig.2, designation 9 represents a deformed metal section, which has been provided with filler.

Die Funktinsweise sieht wie folgt aus:The functionality is as follows:

Wird das Gehäuse 7 auf die "gesunde" metallene Hache 9 gehalten , so hat der Magnet 5 infolge magnetischer Gesetzmäßigkeiten , sowie durch den Federkontaktschalter 4 , den Drang sich dem Untergrund 9 zu nähern. Diesen Kräften in Richtung Untergrund 8 wirkt nun die Kraft der Feder 1 entgegen, die durch rein oder rausdrehen der Eichschraube3 so einreguliert wird , daß bei optimaler Einstellung diese Kraft minimal den beiden entgegengesetzt wirkenden Kräften unterlegen ist, Federkontaktschalter 4 also geschlossen ist.
Führt man nun das Gerät über die gesammte zu prüfende Fläche verhinder Füzbelag 6 das Verkratzen.
Kommt man mit dem Gerät nun über eine Stelle wie sie in Punkt 9 der Fig.2 dargestellt ist, so ändert sich die Kraftverteilung , da die magnetische Zugkraft in Richtung Untergrund nun der Zugkraft der Feder 1 unterliegt. Federkontaktschalter 4 ist also geöffhet.Spachtelmasse 10 kaschiert hier eine Beule.Sichtbar ist jedoch in beiden Fällen eine glatte lackierte Oberfläche.
If the housing 7 is held on the "healthy" metal surface 9, the magnet 5 has the urge to approach the base 9 due to magnetic laws and the spring contact switch 4. These forces in the direction of the base 8 are now counteracted by the force of the spring 1, which is adjusted by turning the calibration screw 3 in or out so that with the optimal setting this force is minimally inferior to the two opposing forces, i.e. the spring contact switch 4 is closed.
If you now move the device over the entire surface to be tested, the foot pad 6 prevents scratches.
If the device is now moved over a spot as shown in point 9 of Fig. 2, the force distribution changes, as the magnetic pulling force towards the surface is now subject to the pulling force of spring 1. Spring contact switch 4 is therefore open. Filler 10 conceals a bump here. However, in both cases a smooth, painted surface is visible.

Die Funktionsweise wie sie in den Figuren 1 und 2 dargestellt ist, beschränkt sich auf das Schalten des Federkontaktschalters 4 , der in einen entsprechenden Schaltkreis integriert, z.b mit einem Signallämpchen oder einem akustischen Signal, die jeweilige Veränderung anzeigt . Der Federkontaktschalter 4 , dessen jeweiliges Öffnen und Schließen sich, wie dargestellt, hinsichtlich seiner Sesibilität einstellen läßt , ist in seiner Aussagekraft beschränkt , da er den Schaltkreis schließt oder öffnet.The functionality as shown in Figures 1 and 2 is limited to the switching of the spring contact switch 4, which is integrated into a corresponding circuit, e.g. with a signal lamp or an acoustic signal, which indicates the respective change. The spring contact switch 4, whose opening and closing can be adjusted in terms of its sensitivity, as shown, is limited in its informative value, since it closes or opens the circuit.

Um übersichtlich Abstufungen in Bezug auf das Vorhandensein der metallenen Substanz zu sehen , kann an Stelle des Federkontaktschalters 4 auch ein regelbarer Widerstand eingesetzt werden, welcher bei Änderung der Zugkraft seinen Widerstand verändert. Diese Veränderung läßt sich dann stufenlos über ein Meßinstrument, im Schaltkreis integriert, darstellen.In order to clearly see the gradations in relation to the presence of the metal substance, an adjustable resistor can be used instead of the spring contact switch 4, which changes its resistance when the pulling force changes. This change can then be displayed continuously using a measuring instrument integrated in the circuit.
