Abstract

The universally-jointed socket wrench has a shaft with a ball end (3) in which is located the internal bolt (4) which is penetrated by the support bolt (5) that carries the ball joint nut (6). A cup spring (8) is located against the inner undercut leading face of the internal hexagonal or square ball joint nut and and on the ball end. This spring stabilises and holds constant the feeding pressure between the head and ball joint nut no matter how often or how long the tool is utilised.

Description

II Kugelgelenk-Steckschlüssel " Kugelgelenk-Steckschlüssel sowohl als lange schlanke Schlüssel als auch als Schlüsselnuß sind.seit langem bekannt und werden in jeder kleinsten werkstatt mehrfach benutzt, und zwar insbesondere zum Festzug oder der Lösung von versteckt liegenden Schraubenköpfen oder Muttern, wobei es sich um Vier- oder Sechskantköpfe oder -Muttern od. dgl. handeln kann.II ball joint socket wrench "ball joint socket wrench both have been known for a long time as a long slim key and as a key nut and are used several times in every smallest workshop, especially in particular for tightening or loosening hidden screw heads or nuts, which can be square or hexagonal heads or nuts or the like.

lilese bekannten Kugelgelenk-Steckschlüssel, die auch einen Vorsatz zur Lösung oder dem Festzug von Zylinderkopfschlitzschrauben tragen können, werden-vom hersteller in der Regel so gefertigt, daß das Kugelgelenk in seinen verstellbaren Achsen stehen bleitt, Jvie es der Monteur bei seiner Arbeit einstellt, um z.Bh eine versteckt liegende Schraube lösen zu können, Mit zunehmender Benutzung dieser bekannten Kugelgelenk-Steckschlüssel nutzen sich aber die aufeinander reibenden Flächen ab und der freie Teil-des Sugelgelenks fällt infolge seines Eigengewichtes immer nach unten ab und ist es vielfach unmöglich, z.B.lilese well-known ball joint socket wrench, which also has an intent to the solution or the Wear tightening of cylinder head slotted screws can, are usually manufactured by the manufacturer in such a way that the ball joint is in its adjustable axes stop, Jvie it is the fitter at his work adjusts, e.g. to be able to loosen a hidden screw, with increasing However, using this known ball joint socket wrench use each other rubbing surfaces and the free part of the ball joint falls due to its own weight always downwards and it is often impossible, e.g.

eine versteckt liegende Mutter in waagerechter Richtung ordnungsgemäß aufzuschrauben, da der freie Teil des Kugelgelenksteckschlüssels mit dem Gewicht der mutter stets in Schrägstellung nach unten fällt.a hidden nut in a horizontal direction properly unscrewed because the free part of the ball joint socket wrench with the weight the nut always falls down at an angle.

Man hat veisucht, diesem Überstand dadurch beizukommen, indem man auf den Schlüsselschaft eine Druckfeder aufgebracht hat, die mit ihrem vorderen Ende gegen die Steckschlüsselnuß drückt und damit als Bremse gegen selbsttätige Verdrehung der Steckschlüsselnuß wirkt. Dies hilft zwar dem vorbeschriebenem Übelstand etwas ab, hat aber andererseits viele achteile, z.B. wird der Schlüsselschaft hierdurch verstärkt und ist nicht mehr so schlank wie er sein sollte.It has been attempted to get rid of this excess by has applied a compression spring to the key shaft, which with its front End presses against the socket wrench nut and thus acts as a brake against automatic Turning the socket wrench nut acts. This helps the above-described disadvantage something off, but on the other hand it has many disadvantages, e.g. the key shaft becomes thereby reinforced and is no longer as slim as it should be.

Diese und weitere Nachteile zu beseitigen ist Aufgabe vorliegender Erfindung, deren Lössung dadurch gekennzeichnet ist, daß einerseits zwischen dem Kugelkopf und andererseits gegen die innere Stirnfläche der Kugelgelenknuß eine Tellerfeder angeordnet ist.The present task is to eliminate these and other disadvantages Invention, the solution is characterized in that on the one hand between the Ball head and on the other hand against the inner end face of the ball joint socket one Disc spring is arranged.

Wie die Neuerung im einzelnen ausgeführt sein kann ergibt sich aus der nachfolgenden Beschrei- bung und aus den Zeichnungen, in denen ein Ausführungsbeispiel zum Teil schematisch dargestellt ist, und zwar zeigen Fig. 1 eine Seitenansicht auf den kompl. Erfindungsgegenstand-Fig. 2 eine vertikale Schnittzeichnung durch den Xugelgelenk-Steckschlüsselkopf Figo 3- die Tellerfeder einzeln dargestellt in zwei Ansichten Der bekannte Steckschlüsselschaft 1 trägt, wie ebenfalls bekannt, an seinem vorderen Ende 2 den bekannten Kugelkopf 1. In dem Kugelkopf 3 ist, wie ebenfalls bekannt, der Innenbolzen 4 gelagert, der durchdrungen ist durch den Dragbolzen 5, der die Kugelgelenknuß 6 trägt. Bei Verstellung oder Verdrehung während der Arbeit des ganzen Kugelgelenkkopfes 3-6 läßt sich dieser in die Achslagen 7 oder-Abschnitte hiervon verstellen und hat die vorbenannte Kugelgelenknuß 6 in ihrem vorderen inneren Teil den bekannten Innensechs- oder Vierkant, der bisher mit seiner inneren hinterschnittenen Stirnfläche auf dem Kugelkopf 3 bei Verdrehung oder Einstellung schleifte. Je nachdem, mit welcher Passung dieser chleifvorgang erfolgte, umso leichter oder schwerer verdrehte sich der ganze Kugelgelenkkopf.How the innovation can be carried out in detail emerges from of the following description exercise and from the drawings in which an exemplary embodiment is shown partially schematically, namely, Fig. 1 is a side view of the compl. Subject of the invention-Fig. 2 is a vertical sectional drawing The diaphragm spring is shown individually by the ball-and-socket socket wrench head Figo 3- in two views The well-known socket wrench shaft 1 carries, as is also known, at its front end 2 the known ball head 1. In the ball head 3 is how also known, the inner bolt 4 is supported, which is penetrated by the drag bolt 5, which carries the ball joint socket 6. When adjusting or twisting during work of the whole ball joint head 3-6 this can be in the axial positions 7 or sections adjust this and has the aforementioned ball joint socket 6 in its front interior Part of the well-known hexagon socket or square, which was previously undercut with its inner The face on the ball head 3 grinded when twisted or adjusted. Depending on, The fit with which this grinding process was carried out, the easier or harder it is to twist the whole ball joint head.

Erfindungsgemäß ist aber nun in dem Raum auf dem Kugelkopf 3 und gegen die Innere hinterschnittene Stirnfläche des Innensechs- oder Vierkant eine Tellerfeder 8 gelegt, die den Schleifdruck zwischen Kugelkopf 3 und Kugelgelenknuß 6 sta- bilisiert und konstant hält, gleichgultig wie oft und wie lange das Werkzeug benutzt wird, Es ist dies zwar eine sehr einfache und billige Verbesserung des ganzen~Kugelgelenk-Steckschlüssels, aber eine außerordentlich wertvolle und fortschrittliche, die sich eben durch ihre Einfachheit kennzeichnet.According to the invention, however, is now in the space on the ball head 3 and against the inside undercut face of the hexagon socket or square is a disc spring 8, which sta- bilized and keeps it constant, no matter how often and how long the tool is used, Although this is a very simple and cheap improvement on the whole ~ ball joint socket wrench, but an extraordinarily valuable and progressive one that stands out precisely through its Characterizes simplicity.

Die Neuerung ist nicht auf die dargestellten Einzelheiten beschränkt, vielmehr auh abgeändert ausführbar, sofern nur die krfindungsmerk male zum Ausdruck kommen.The innovation is not limited to the details shown, Rather, it can also be executed in modified form, provided that only the identification features are expressed come.
