Abstract

When changing the wheel of a car it is often difficult to undo the retaining nuts with the nut wrenches which are supplied with the standard tool kit. This problem is overcome by using a telescopic tube consisting of three sections (1) (2) (3) with the larger end (1) fitting over one of the arms of the cruciform wrench (4). A slot in the end (1a) of the tube (1) fits over the arm of the wrench to hold the tube in place. The telescopic construction of the lever arm enables it to be stored in the car tool box.

Description

Hilfsmittel zum Lösen von festgezogenen RadmutternTool for loosening tightened wheel nuts

mittels eines Kreuzschlüssels.using a cross wrench.

Die Erfindung bezieht sich auf ein neuartiges Hilfsmittel zum Lösen von festgezogenen Radmuttern mittels eines Kreuzschlüssels.The invention relates to a novel aid for loosening of tightened wheel nuts using a cross wrench.

Immer wieder stellen Autofahrer bei einem Reifenwechsel fest, daß die Radmuttern besonders durch das mechanische Anziehen derselben so fest sitzen, daß ein Lösen mit den üblichen Werkzeugen besonders für nicht so kräftige Personen, wie z.B. Frauen sehr schwer ja oft unmöglich ist.Again and again when changing tires, drivers find that the wheel nuts are so tight, especially by mechanically tightening them, that loosening with the usual tools especially for not so strong people, like, for example, women are very difficult and often impossible.

Man versucht sich bisher damit zu helfen, ein längeres Rohr mitzuführen, um mit demselben die Hebekraft zu vergrößern. Solche Rohre passen aber in ihren Längen nicht in den für das übliche Werkzeug vorgesehenen Raum und müssen gesondert im Kofferraum untergebracht werden, wo sie lose liegend beim Fahren und Bremsen hin- und herrollen könnens Zur Behebung dieses Nachteiles wird das Wesen der Erfindung darin erblickt, daß drei teleskopartig ineinander schiebbare und wieder ausziehbare Rohrabschnitte im ausgezogenen Zustande einen Schenkel des Kreuzschlüssels übergreifend als Hebel wirksam sind und im zusammengeschobenen Zustand in dem für das Werkzeug vorgesehenen Platz unterzubringen sind. Es ist dabei vorgesehen, daß am freien Ende des vorderen ohrabschnittes eine U-förmige Aussparung zum Übergreifen des biittelstückes des Kreuzschlüssels und ein Ansatz ähnlich einer Schraubendreherklinge zum Abheben der Radkappe angeordnet ist.So far, people have tried to help themselves by carrying a longer pipe with them, in order to increase the lifting force with the same. Such pipes fit into theirs Lengths not in the space provided for the usual tools and must be carried out separately be housed in the trunk, where they lie loosely when driving and braking Being able to roll back and forth To remedy this disadvantage is the essence of the invention sees in it that three telescopically into one another sliding and again extendable pipe sections in the extended state a leg of the cross wrench are effective across the board as a lever and when pushed together in the for the tools are to be accommodated in the space provided. It is provided that at the free end of the front ear section a U-shaped recess to reach over of the middle piece of the cross wrench and an approach similar to a screwdriver blade is arranged to lift off the hubcap.

In der Zeichnung ist der Erfindungsgegenstand beispielsweise dargestellt . Es zeigt Fig. 1 das hebelartige Hilfsmittel im zusammengeschobenen Zustand, Fig. 2 dasselbe im ausgezogenen Zustand, teilweise im Schnitt in Funktion und Fig. 3 dasselbe im ausgezogenen Zustand im Schnitt.In the drawing, the subject matter of the invention is shown, for example . It shows Fig. 1 the lever-like aid in the pushed together state, Fig. 2 the same in the extended state, partially in section in function and FIG. 3 the same in the extended state in section.

Nach der Zeichnung ist 1 der den reuzschlüssel 4 angreifende Rohrabschnitt mit der U-förmige Aussparung Ib und der Klinge ia.According to the drawing, 1 is the pipe section attacking the key 4 with the U-shaped recess Ib and the blade ia.

2 und 3 sind die z!ei weiteren Rohrabschnitte, die in dem Rohrabschnitt 1 einschiebbar sind und im ausgezogenen Zustand arretiert werden. 3a ist ein mit dem Rohrabschnitt 3 verbundener Handgriff.2 and 3 are the two further pipe sections which are included in the pipe section 1 can be pushed in and locked in the extended state. 3a is a with the pipe section 3 connected handle.
