Die Erfindung betrifft eine Steckschlüsselverlängerung mit einem mehrkantigen Einsteckteil am einen und einem entsprechend gestalteten Aufnahmeteil am anderen Ende, wobei das Einsteckteil mit einem aus einer der Schlüsselflächen teilweise heraustretenden Arretierelement versehen ist, und wobei ein Druckübertragungselement, 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, axial in dem Einsteckteil geführt ist.The invention relates to a socket wrench extension with a polygonal Insert part on one and a correspondingly designed receiving part on the other end, the male part with one of one of the key faces partially emerging locking element is provided, and wherein a Pressure transmission element, one end of which is cone-shaped or button-shaped designed the pressure actuation of the pressure transmission element is used and the other end of which is part of a mechanism for implementing a Direction of the plug-in axial movement of the Pressure transmission element in an outward movement of the Locking element is guided axially in the plug-in part.
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. Mutter Haftreibungskräfte ergeben, die größer als die Arretierkräfte des federbelasteten Arretierelementes sind. The task of the mentioned locking element is, under spring tension in a appropriately designed recess of that receiving part to snap into which insert part of the socket wrench extension is used. In as a rule, this is the receiving part of the socket wrench insert. As a result of Snap the locking element into the recess should be too easy Separation of the two tool parts should be prevented, these should only be under Application of a certain axial force can be connected and later released again his. Nevertheless, unintentional loosening can often occur, for example if the socket wrench extension is locked with one Socket wrench insert slightly tilted by one screw or mother must be removed. Here you can choose between Socket wrench insert and screw or nut result in static friction forces, which are greater than the locking forces of the spring-loaded locking element.
Eine gattungsgemäße Steckschlüsselverlängerung ist aus der US 5,289,745 bekannt. Diese Steckschlüsselverlängerung ist als einstückiges Bauteil ausgebildet, das je nach Ausführungsform eine zentrisch oder exzentrisch angeordnete Längsbohrung zur Aufnahme einer Betätigungsstange aufweist. Die Längsbohrung ist entweder als Durchgangsbohrung oder als Sacklochbohrung ausgebildet. Während ersteres eine Endkappe an der Stirnseite des mehrkantig ausgebildeten Einsteckabschnitts erfordert, ist bei letzterem ein über eine Unterlegscheibe und einen Sprengring gehaltener Anschlagring in einer sich an den Aufnahmeabschnitt anschließenden Bohrung vorgesehen, um die axiale Fixierung der Betätigungsstange zu bewirken. Nachteilig bei der bekannten Steckschlüsselverlängerung ist, daß die axiale Führung der Betätigungsstange ausnahmslos durch die Längsbohrung erfolgt, so daß hohe Anforderungen an die Fertigungstoleranz zur Erzielung einer präzisen Führung zu stellen sind, was zu einer kostenaufwendigen Fertigung führt. Ein weiterer Nachteil der bekannten Steckschlüsselverlängerung ist, daß das Arretierelement in einer Querbohrung im Einsteckabschnitt entweder mit einer Sicherungsschraube oder einer Endkappe gegen Herausfallen zu sichern ist. Dies hat eine hohe Bauteilanzahl und damit eine kostenintensive Fertigung und Montage zur Folge.A generic socket wrench extension is from US 5,289,745 known. This socket wrench extension is a one-piece component formed, depending on the embodiment, a centric or eccentric arranged longitudinal bore for receiving an actuating rod. The longitudinal hole is either as a through hole or as Blind hole trained. While the former has an end cap on the Front end of the polygonal insertion section requires is at the latter one held over a washer and a snap ring Stop ring in a bore adjoining the receiving section provided to effect the axial fixation of the actuating rod. A disadvantage of the known socket wrench extension is that the axial The actuation rod is guided through the longitudinal bore without exception, so that high demands on the manufacturing tolerance to achieve a Precise guidance is required, resulting in costly manufacturing leads. Another disadvantage of the known socket wrench extension is that either with the locking element in a transverse bore in the insertion section a locking screw or an end cap to prevent it falling out is. This has a high number of components and thus a cost-intensive production and assembly result.
Der Erfindung liegt die Aufgabe zugrunde, eine Steckschlüsselverlängerung dahingehend weiterzubilden, daß sich bei einfacher Montage und verringerten Herstellkosten eine hohe Funktionspräzision erzielen läßt.The invention has for its object to develop a socket wrench extension in such a way that high functional precision can be achieved with simple assembly and reduced manufacturing costs.
Diese Aufgabe ist bei einer Steckschlüsselverlängerung der oben genannten Art erfindungsgemäß gelöst durch ein das Einsteckteil mit dem Aufnahmeteil starr verbindendes Rohr, in dem das Druckübertragungselement angeordnet ist, und eine Führungsbuchse für die axiale Führung des Druckübertragungselements in dem Aufnahmeteil, die in eine Durchgangsbohrung des Aufnahmeteils eingesetzt und vorzugsweise eingepreßt ist, wobei der Einsetz- bzw. Einpreßdurchmesser der Führungsbuchse größer als der maximale Durchmesser des Druckübertragungselementes ist. This object is achieved with a socket wrench extension of the aforementioned type according to the invention by the insertion to the receiving part rigidly connecting pipe in which the pressure transmission element is disposed, and a guide bush for the axial guidance of the pressure-transmitting element in the receiving part, which is inserted into a through bore of the receiving part and is preferably pressed in, the insertion or press-in diameter of the guide bushing being greater than the maximum diameter of the pressure transmission element.
Eine solchermaßen ausgestaltete Steckschlüsselverlängerung ermöglicht eine einfache und schnelle Montage, die demzufolge mit einer kostengünstigen Herstellung einhergeht. Ursächlich hierfür ist, daß sich das Arretierelement vor Zusammenbau der Steckschlüsselverlängerung in das Einsteckteil durch die für das Druckübertragungselement vorgesehene Bohrung einführen läßt und damit nach Einsetzen des Druckübertragungselements ohne zusätzliche Sicherungselemente in dem Einsteckteil gehalten wird. Nachdem anschließend Aufnahmeteil, Einsteckteil und Rohr miteinander verbunden worden sind, kann das Druckübertragungselement durch die Durchgangsbohrung für die Führungsbuchse eingesetzt werden, und zwar insbesondere deswegen, weil der Einsetz- bzw. Einpreßdurchmesser der Führungsbuchse größer ist als der maximale Durchmesser des Druckübertragungselements. Durch das abschließende Einsetzen der Führungsbuchse erhält das Druckübertragungselement eine axiale Führung und wird in axialer Richtung fixiert. Die Führungsbuchse kann aus einem für die axiale Führung besonders geeigneten Material mit geringem Reibkoeffizienten bestehen.Such a socket wrench extension enables one simple and quick installation, which consequently is inexpensive Manufacturing goes hand in hand. The reason for this is that the locking element in front Assemble the socket wrench extension into the insert by the for allows the pressure transmission element to insert the provided bore and thus after insertion of the pressure transmission element without additional Fuse elements are held in the insert part. After then Receiving part, insert part and tube have been connected to each other the pressure transmission element through the through hole for the Guide bushing are used, especially because the insertion or press-in diameter of the guide bushing is larger than that maximum diameter of the pressure transmission element. By the final insertion of the guide bushing receives this Pressure transmission element has an axial guide and is in the axial direction fixed. The guide bushing can be specially made for axial guidance suitable material with a low coefficient of friction.

In dem Einsteckteil der Steckschlüsselverlängerung ist das Druckübertragungselement geführt, dessen eines Ende den Druck überträgt und dessen anderes Ende Bestandteil eines Mechanismus ist, um die Bewegung des Druckübertragungselementes in eine Auswärtsbewegung des Arretierelementes zu überführen. In einer Ausgestaltung der Erfindung wird vorgeschlagen, daß das andere Ende des Druckübertragungselementes mit einer Schräge versehen ist, die an dem radial geführten Arretierelement anliegt.The socket wrench extension according to the invention is a very good one Hold of the inserted socket wrench on the Socket extension achieved. In the insert part of the Socket wrench extension is the pressure transmission element, whose one end transmits the pressure and the other end is part of one Mechanism is to move the pressure transmission element into a To transfer outward movement of the locking element. In a Embodiment of the invention it is proposed that the other end of the Pressure transmission element is provided with a bevel, which on the radial guided locking element is present.
Zur Erzielung einer Rückstellkraft wird gemäß einer weiteren Ausgestaltung der Erfindung eine Feder vorgeschlagen, welche eine auf das Zapfen- oder Tastenende hin gerichtete Druckkraft auf das Druckübertragungselement ausübt. Vorzugsweise stützt sich hierbei die Feder mit ihrem einen Ende an dem Einsteckteil und mit ihrem anderen an dem Druckübertragungselement ab. In order to achieve a restoring force, according to a further embodiment the invention proposed a spring, which one on the pin or Pushing force directed towards the end of the button on the pressure transmission element exercises. The spring is preferably supported with one end the male part and with their other on the pressure transmission element from.
Weitere Einzelheiten, Merkmale und Vorteile des Gegenstandes der Erfindung werden nachfolgend anhand eines auf der Zeichnung dargestellten Ausführungsbeispieles erläutert. Die einzige Figur zeigt eine Steckschlüsselverlängerung in einer Schnittdarstellung.Further details, features and advantages of the subject matter of the invention are shown below using one of the drawings Embodiment explained. The only figure shows one Socket wrench extension in a sectional view.
Die im Rahmen eines Steckschlüsselsystems verwendbare Verlängerung
besteht aus einem Aufnahmeteil 1 mit einem darin eingeformten
Innenvierkant, einem Einsteckteil 2 mit einem daran als Schlüsselfläche 21
ausgebildeten Außenvierkant 5 sowie einem Rohr 3, welches Aufnahmeteil 1
und Einsteckteil 2 starr miteinander verbindet. Die Schlüsselflächen von
Aufnahmeteil 1 und Einsteckteil 2 entsprechen den international üblichen und
genormten Abmessungen für Steckschlüsselsysteme.The extension that can be used as part of a socket wrench system
consists of a receiving
In an sich bekannter Weise ist das Einsteckteil 2 in einer der Schlüsselflächen
21 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
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 is pressed back
Locking element 4 in the radial bore 6 against the force of one there
arranged spring. 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 Stange an. Das
Druckübertragungselement 8 ist in einer Längsbohrung 9 des Einsteckteiles 2
geführt und weist an seinem Ende eine Schräge 10 auf, welche innen an dem
kugelförmigen Arretierelement 4 anliegt. Innerhalb des Rohres 3 stützt sich
das Druckübertragungselement 8 mittels einer Feder 11 an der inneren
Stirnfläche des Einsteckteils 2 ab. 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 Aufnahmeteil 1 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
Pressure transmission element 8 in the form of a rod. The
Pressure transmission element 8 is in a longitudinal bore 9 of the
Die als Druckübertragungselement 8 dienende Stange ist außerdem auch im
Aufnahmeteil 1 axial geführt. Hierzu ist in eine Durchgangsbohrung 12 des
Aufnahmeteiles 1 eine Führungsbuchse 13 eingepreßt, die wiederum das
Druckübertragungselement 8 axial führt, und die ferner einen Anschlag bildet,
der den Längsweg des Druckübertragungselementes 8 begrenzt. Der
Einsetzdurchmesser der Führungsbuchse 13 ist größer als der maximale
Durchmesser des Druckübertragungselementes 8. Auf diese Weise wird eine
erleichterte Montage von Druckübertragungselement 8 und Feder 11
ermöglicht.The serving as a pressure transmission element 8 is also in
Receiving
Zum Zusammenbau der in der Zeichnung dargestellten
Steckschlüsselverlängerung wird zunächst das kugelförmige Arretierelement 4
durch die Längsbohrung 9 hindurch in seine Radialbohrung 6 verbracht,
anschließend werden Aufnahmeteil 1, Einsteckteil 2 und Rohr 3 miteinander
verbunden, vorzugsweise durch Verpressen in der Innenwandung des Rohres
3. Sodann wird vom Aufnahmeteil 1 her das Druckübertragungselement 8 mit
der daran vorläufig befestigten Feder 11 durch die Steckschlüsselverlängerung
hindurch bis in die dargestellte Stellung geführt. Schließlich wird, ebenfalls
durch den Innenvierkant 15 hindurch, die Führungsbuchse 13 eingesetzt und
in der Durchgangsbohrung 12 verpreßt.To assemble the shown in the drawing
Socket wrench extension first becomes the spherical locking element 4
brought through its longitudinal bore 9 into its radial bore 6,
then receiving
Die Länge des Druckübertragungselementes 8 ist dergestalt, daß dieses mit
einem zapfenförmigen Ende 14 aus der Führungsbuchse 13 heraus- und in
den Innenvierkant 15 des Aufnahmeteils 1 hineinragt. Das zapfenförmige Ende
14 dient auf diese Weise der Druckbetätigung des
Druckübertragungselementes 8, sobald in den Innenvierkant 15 ein
entsprechender Außenvierkant, z. B. eines Ratschenschlüssels, eingeführt
wird. Das Druckübertragungselement 8 übernimmt hierbei die Funktion eines
Stößels, dessen axiale Bewegung über die Schräge 10 auf eine radial nach
auswärts gerichtete Bewegung des Arretierelementes 4 übertragen wird, so
daß dieses in der in der Zeichnung in ausgezogener Linie dargestellten Stellung
fest arretiert. Ein dort aufgesteckter Steckschlüssel kann sich dann auch unter
Kraftwirkung nicht mehr lösen. The length of the pressure transmission element 8 is such that this with
