Die Erfindung betrifft eine Steckschlüsselverlängerung mit einem mehrkantigen, Schlüsselflächen aufweisenden Einsteckteil am einen und einem entsprechend gestalteten Aufnahmeteil am anderen Ende und mit einem Gelenk zwischen Aufnahmeteil und Einsteckteil, wobei das Einsteckteil mit einem aus einer der Schlüsselflächen teilweise heraustretenden Arretierelement versehen ist, mit einem axial in dem Einsteckteil geführten Druckübertragungslement, dessen eines Ende zapfen- oder tastenförmig gestaltet der Druckbetätigung des Druckübertragungselementes dient und dessen anderes Ende Bestandteil eines Mechanismus zur Umsetzung einer in Richtung auf das Einsteckteil gerichteten Axialbewegung des Druckübertragungselementes in eine Auswärtsbewegung des Arretierelementes ist.The invention relates to a socket wrench extension with a polygonal, Insert part with wrench flats on one and one accordingly designed receiving part at the other end and with a joint between Receiving part and plug-in part, the plug-in part with one of the Key surfaces partially protruding locking element is provided with an axially guided in the plug-in pressure transmission element, one of which The end of the button or button-shaped design of the push button Pressure transmission element is used and the other end part of one Mechanism to implement a directed towards the male part Axial movement of the pressure transmission element in an outward movement of the Locking element is.
Aufgabe des genannten Arretierelementes ist es, unter Federspannung in eine entsprechend gestaltete Ausnehmung jenes Aufnahmeteiles einzurasten, in welches das Einsteckteil der Steckschlüsselverlängerung eingesetzt wird. In der Regel ist dies das Aufnahmeteil des Steckschlüsseleinsatzes. Infolge des Einrastens des Arretierelementes in die Ausnehmung soll ein zu leichtes Trennen der beiden Werkzeugteile verhindert werden, diese sollen nur unter Anwendung einer gewissen axialen Kraft verbindbar und später wieder lösbar sein. Gleichwohl kann es oft zu einem unbeabsichtigten Lösen kommen, etwa wenn die Steckschlüsselverlängerung mit einem daran arretierten Steckschlüsseleinsatz in leicht verkanteter Ausrichtung von einer Schraube oder Mutter abgezogen werden muß. Hierbei können sich zwischen Steckschlüsseleinsatz und Schraube bzw.

Eine Steckschlüsselverlängerung mit den eingangs genannten Merkmalen ist aus der WO 95/08720 A1 bekannt. Hierbei ist das Druckübertragungselement mit einem Betätigungselement etwa in Gestalt eines Schwenkhebels oder eines Schiebers verbunden, unter dessen Verwendung das Druckübertragungselement von einer Verriegelungsstellung in eine Entriegelungsstelle bzw. von einer weniger in eine stärker sichernde Stellung für das kugelförmige Arretierelement überführbar ist. Erforderlich ist daher eine gesonderte Betätigung des Betätigungselements, um die jeweils gewünschte Stellung des Arretierelements herbeizuführen. Im Hinblick auf den oftmals in hektischen Situationen erfolgenden Einsatz von Steckschlüsselverlängerungen, etwa in KFZ-Reparaturwerkstätten, ist jedoch jedwede zusätzliche manuelle Handhabung beim Ver- und Entriegeln des Arretierelementes unbefriedigend.A socket wrench extension with the features mentioned above is out WO 95/08720 A1 known. The pressure transmission element is included an actuating element in the form of a pivot lever or a Slider connected, using the pressure transmission element from a locking position to an unlocking point or from one less can be transferred into a more secure position for the spherical locking element is. It is therefore necessary to actuate the actuating element separately, to bring about the desired position of the locking element. in the With regard to the often used in hectic situations Socket wrench extensions, for example in car repair shops, is any additional manual handling when locking and unlocking the Locking element unsatisfactory.
Der Erfindung liegt die Aufgabe zugrunde, eine Steckschlüsselverlängerung mit verbessertem Halt des angesetzten Steckschlüsseleinsatzes und vergleichsweise einfacher Handhabung zu schaffen.The invention has for its object to provide a socket wrench extension with improved hold of the inserted socket wrench insert and comparatively simple handling.
Zur Lösung dieser Aufgabe wird bei einer Steckschlüsselverlängerung der eingangs genannten Art vorgeschlagen, daß ein an dem Einsteckteil schwenkbar gelagertes Element des Gelenks eine bezüglich der Drehachse mit einem Exzenter versehene Druckübertragungsfläche aufweist, an der das zapfen- oder tastenförmige Ende des Druckübertragungselementes anliegt, wobei sich die größte Weite des Exzenters dann einstellt, wenn Aufnahmeteil und Einsteckteil in gerader Ausrichtung zueinander angeordnet sind.To solve this problem, it is proposed in a socket wrench extension of the type mentioned that a pivotally mounted element of the joint on the plug-in part has an eccentric pressure transmission surface with respect to the axis of rotation, against which the pin-shaped or button-shaped end of the pressure transmission element rests, the sets the largest width of the eccentric when the receiving part and the insert part are arranged in a straight alignment to one another.
Die erfindungsgemäße Steckschlüsselverlängerung ist mit einem Gelenk zwischen Einsteckteil und Aufnahmeteil versehen sein, insbesondere einem allseitig schwenkbaren Kardangelenk. Bei einer mit einem solchen Gelenk versehenen Steckschlüsselverlängerung ist der Verlängerungseffekt nur sekundär angestrebt, in erster Linie geht es um die Bereitstellung einer unter einem Winkel ansetzbaren Steckschlüsselverbindung für das Arbeiten an Stellen, die in Längsrichtung nicht erreichbar sind. Insofern soll auch ein Kardangelenk als Steckschlüsselverlängerung im Sinne dieser Erfindung angesehen werden.The socket wrench extension according to the invention is with a joint between Insert part and receiving part be provided, in particular one on all sides swiveling universal joint. In one with such a joint Socket wrench extension is only secondary to the extension effect, primarily it is about providing an angle-attachable Socket wrench connection for working in places that are not in the longitudinal direction are reachable. In this respect, a universal joint is said to be Socket extension can be viewed in the sense of this invention.
Die exzentrische Ausgestaltung des Gelenks erlaubt ein Verriegeln des Einsteckteils mit dem Aufnahmeteil eines Schlüsselaufsatzes durch einfaches Verschwenken der Verlängerung.The eccentric design of the joint allows the Insert part with the receiving part of a key attachment by simple Swiveling the extension.
Mit der erfindungsgemäßen Steckschlüsselverlängerung wird ein wesentlich verbesserter Halt des angesetzten Steckschlüsseleinsatzes an der Steckschlüsselverlängerung erzielt. In dem Einsteckteil der Steckschlüsselverlängerung ist ein Druckübertragungselement geführt, dessen eines Ende als Druckübertragungselement dient und dessen anderes Ende Bestandteil eines Mechanismus ist, mit dem die Bewegung des Druckübertragungselementes in eine Auswärtsbewegung des Arretierelementes überführt wird. In einer Ausgestaltung wird zur Realisierung dieser Bewegungsübertragung vorgeschlagen, daß das andere Ende des Druckübertragungselementes mit einer Schräge versehen ist, die an dem radial geführten Arretierelement anliegt.With the socket wrench extension according to the invention is essential Improved hold of the inserted socket wrench insert on the socket wrench extension achieved. In the plug-in part of the socket wrench extension a pressure transmission element is guided, one end of which is used as a pressure transmission element serves and the other end part of a mechanism with which the movement of the pressure transmission element in a Outward movement of the locking element is transferred. In one embodiment is proposed for the realization of this movement transfer that the other end of the pressure transmission element is provided with a bevel that abuts the radially guided locking element.
Zur Erzielung einer Rückstellkraft wird gemäß einer weiteren Ausgestaltung eine Feder vorgeschlagen, welche eine auf das Zapfen- oder Tastenende hin gerichtete Druckkraft auf das Druckübertragungselement ausübt Vorzugsweise stützt sich die Feder mit ihrem einen Ende an dem Einsteckteil und mit ihrem anderen Ende an dem Druckübertragungselement ab.According to a further embodiment, a Spring proposed, which one directed towards the pin or key end Exerts pressure force on the pressure transmission element is preferably supported the spring with one end on the male part and the other end on the pressure transmission element.
Gemäß einer bevorzugten Ausführungsform der Erfindung ist die Steckschlüsselverlängerung mit einem Kardangelenk zwischen Aufnahmeteil und Einsteckteil versehen, das einen zwischen 0 und 90° beliebigen Winkel zwischen Aufnahmeteil und Einsteckteil ermöglicht.According to a preferred embodiment of the invention, the Socket wrench extension with a universal joint between the receiving part and Insert part that has any angle between 0 and 90 ° Receiving part and insert part enables.
Weitere Einzelheiten, Merkmale und Vorteile des Gegenstandes der Erfindung werden nachfolgend anhand eines auf der Zeichnung dargestellten Ausführungsbeispieles erläutert. Die einzige Figur zeigt in einer Schnittansicht eine Steckschlüsselverlängerung in Gestalt einer Kardangelenk-Verbindung. Further details, features and advantages of the subject matter of the invention are based on an embodiment shown in the drawing explained. The single figure shows a socket wrench extension in a sectional view in the form of a universal joint.
Die im Rahmen eines Steckschlüsselsystems verwendbare Kardangelenk-Verbindung
besteht aus einem Aufnahmeteil 1 mit einem darin eingeformten
Innenvierkant, einem Einsteckteil 2 mit daran ausgebildetem Außenvierkant sowie
u. a. einem Kardanelement 16, welches Aufnahmeteil 1 und Einsteckteil 2 gelenkig
miteinander verbindet. Die Vierkantflächen von Aufnahmeteil 1 und Einsteckteil 2
entsprechen den international üblichen und genormten Abmessungen für Steckschlüsselsysteme.The universal joint connection that can be used as part of a socket wrench system
consists of a receiving part 1 with a molded therein
Inner square, a plug-in part 2 with an outer square formed thereon as well
u. a. a
In an sich bekannter Weise ist das Einsteckteil 2 mit einem Arretierelement 4 in
Gestalt einer Kugel versehen. Beim Einsetzen des Außenvierkantes 5 in einen
Innenvierkant, wie er z. B. im Aufnahmeteil 1 vorgesehen ist, wird das Arretierelement
4 in seiner Radialbohrung 6 zunächst zurückgeschoben und kann
anschließend in einer hierfür vorgesehenen Ausnehmung des Außenvierkantes
einrasten. Eine solche Ausnehmung ist bei dem Aufnahmeteil 1 durch eine
entsprechende Bohrung 7 verwirklicht.In a manner known per se, the plug-in part 2 is provided with a locking element 4 in
Shape of a sphere. When inserting the
Bei bekannten Systemen erfolgt das Zurückdrücken des kugelförmigen Arretierelementes
4 in der Radialbohrung 6 entgegen der Kraft einer dort angeordneten
Feder. Auf diese Weise ist auch die Kraft, mit der der Außenvierkant 5
in einem entsprechenden Innenvierkant gehalten wird, von der Federkraft abhängig.In known systems, the spherical locking element is pushed back
4 in the radial bore 6 against the force of an arranged there
Feather. This is also the force with which the
Demgegenüber liegt gemäß der Zeichnung an dem dort ebenfalls
kugelförmigen Arretierelement 4 nicht unmittelbar eine Feder, sondern ein
Druckübertragungselement 8 in Gestalt einer kurzen Stange bzw. eines Stiftes
an. Das Druckübertragungselement 8 ist in einer Längsbohrung 9 des
Einsteckteiles 2 geführt und weist an seinem einen Ende eine Schräge 10 auf,
welche innen an dem kugelförmigen Arretierelement 4 anliegt. Das andere
Ende 14 ist tastenförmig gestaltet, und seine Rückseite dient als Anlagefläche
für eine auf Druck wirkende Feder 11. Die Feder 11 ist so angeordnet, daß sie
auf das Druckübertragungselement 8 eine Kraft ausübt, welche bestrebt ist,
das Druckübertragungselement 8 von dem Einsteckteil 2 weg und in Richtung
auf das Kardanelement 16 zu bewegen. Da die Schräge 10 in Verbindung mit
dem Arretierelement 4 einen Mechanismus zur Umsetzung der Axialbewegung
des Druckübertragungselementes 8 in eine im wesentlichen radiale Bewegung
des Arretierelementes 4 bildet, bewirkt die Feder 11 in ihrem entspannten
Zustand zugleich, daß sich das kugelförmige Arretierelement 4 in seiner
Radialbohrung 6 nach innen zurückziehen kann. Hierzu sind selbstverständlich
Maßnahmen getroffen, um ein Herausfallen der in diesem Zustand
beweglichen Kugel aus dem Einsteckteil 2 zu verhindern.In contrast, according to the drawing is due to the same there
spherical locking element 4 not directly a spring, but a
Das Kardanelement 16, welches über einen ersten Bolzen 17 mit dem Einsteckteil
2, und über einen zweiten Bolzen 18 mit dem Aufnahmeteil 1 gelenkig
verbunden ist, weist bezüglich der Drehachse 19 des Bolzens 17 eine mit
einem Exzenter versehene Druckübertragungsfläche 20 auf. Die Druckübertragungsfläche
20 liegt auf dem tastenförmigen Ende 14 des Druckübertragungselementes
8 an, wobei, wie die Zeichnung erkennen läßt, die
exzentrisch gestaltete Druckübertragungsfläche 20 dort den größten Abstand
von der Drehachse 19 aufweist, wo das tastenförmige Ende 14 bei gerader
gegenseitiger Ausrichtung von Aufnahmeteil 1 und Einsteckteil 2 anliegt.The
Im Falle der auf der Zeichnung erkennbaren Auslenkung zwischen
Aufnahmeteil 1 und Einsteckteil 2 gibt die exzentrische
Druckübertragungsfläche 20 das Druckübertragungselement 8 frei, so daß
sich dieses unter der Wirkung der Feder 11 von dem kugelförmigen
Arretierelement 4 entfernt und das Arretierelement 4 vollständig in seine
Radialbohrung 6 hineingelangen kann. Bei einem Zurückschwenken des
Aufnahmeteils 1 hingegen wird das Druckübertragungselement 8 durch die
exzentrische Druckübertragungsfläche 20 in das Einsteckteil 2
hineingeschoben, wodurch das Arretierelement 4 in einer äußeren Stellung, in
der es noch zum Teil aus der Schlüsselfläche 21 herausragt, gesperrt wird. Ein
dort aufgesteckter Steckschlüssel kann sich dann auch unter Kraftwirkung
nicht mehr lösen.In the case of the deflection between
Receiving part 1 and insert part 2 gives the eccentric
Die exzentrisch gestaltete Kontur der Druckübertragungsfläche 20 ist dabei so
gewählt, daß die Freigabe des Arretierelementes 4 erst dann erfolgt, wenn,
