Abstract

A lifting bar (28) has a cone-shaped end (30) for contact with a ball (26). The extension (10) comprises a basis body (14), a polygonal profile (20) provided on the basis body with a hole (24) in one side (18), a lifting bar extending into an axial bore (16), a ball in the hole in the side of the profile, and a setting bar (34) extending perpendicular to the lifting bar. Both bars are engaged with each other so that linear movement of the setting bar will change the position of the lifting bar and either lower the ball into its hole or raised the ball out of its hole.

Description

Die Erfindung betrifft eine Kupplungsvorrichtung zum Verriegeln von Steckverbindungen insbesondere bei Werkzeugen, die durch Betätigung eines Auslösegliedes auslösbar ist, so daß die Steckverbindung leicht lösbar ist, gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a coupling device for locking connectors, in particular in tools, which is triggered by actuation of a trigger member, so that the connector is easily detachable, according to the preamble of claim 1.

Eine derartige Kupplungsvorrichtung gelt beispielsweise aus der US 5813296 hervor. Bei Werkzeugen werden häufig verschiedene Teile durch Steckverbindungen mittels eines Mehrkants und einer Mehrkantaufnahme miteinander verbunden. Ein typisches Beispiel hierfür ist das Aufstecken eines an die Form der jeweiligen Schraube oder Mutter angepaßten Steckschlüsseleinsatzes oder das Aufstecken einer Verlängerung auf eine Knarre. Andere Anwendungen sind das Aufstecken eines Quergriffes, eines Übergangsteils, eines Steckgriffes, eines Kardangelenks, eines Gelenkgriffes, einer Kurbel oder eines T-Gelenkschlüssels. Reine Steckverbindungen sind unsicher und können sich leicht lösen. Deshalb sind Kupplungsvorrichtungen mit Rastkugeln oder andere Rastmechanismen vorgesehen, welche die Teile der Steckverbindung, also Mehrkant und Mehrkantaufnahme, zusammenhalten.Such a coupling device gelt for example from the US 5813296 out. In tools often different parts are connected by connectors using a polygon and a polygonal recording. A typical example of this is the attachment of an adapted to the shape of the respective screw or nut socket insert or attaching an extension to a ratchet. Other applications are the attachment of a transverse handle, a transition part, a plug-in handle, a universal joint, a hinge handle, a crank or a T-jointed wrench. Pure connectors are unsafe and can easily come off. Therefore, coupling devices with locking balls or other locking mechanisms are provided, which hold together the parts of the connector, ie polygon and polygonal recording.

Ein Werkzeug, z.B. eine Knarre, weist einen Vierkant auf, der durch Hin- und Herbewegen eines Griffhebels über einen Ratschenmechanismus schrittweise verdrehbar ist. Auf diesem Vierkant sitzt ein Steckschlüsseleinsatz, d.h. ein Werkzeugteil mit einer an die zu verdrehende Schraube oder Mutter angepaßten Formgebung. Dieser Steckschlüsseleinsatz kann zur Anpassung an die Schraube oder Mutter abgezogen und durch einen anderen mit anderer Form ersetzt werden. Der Steckschlüsseleinsatz ist durch eine Rastkugel gesichert. Die Rastkugel kann einfach gegen eine Federkraft beim Abziehen nach innen gedrückt werden. Dazu ist häufig eine nicht unerhebliche Kraft erforderlich, da ja auch größere und somit schwerere Steckschlüsseleinsätze sicher auf dem Vierkant gehalten werden müssen. Da oft die Schraube oder Mutter mit dem normalen Werkzeug nicht erreicht werden können, sind Verlängerungen oder Verbindungswerkzeuge, z.B. Kardangelenke oder Übergangsstücke erforderlich.A tool, such as a ratchet has a square, which gradually rotated by reciprocating a handle lever via a ratchet mechanism is. On this square sits a socket wrench, ie a tool part with an adapted to the screw or nut to be rotated shape. This socket can be removed to fit the screw or nut and replaced with another of a different shape. The socket is secured by a detent ball. The detent ball can be easily pressed against a spring force when pulling inwards. This is often a significant force required, as well as larger and thus heavier sockets must be securely held on the square. Since often the screw or nut can not be reached with the normal tool, extensions or connecting tools, eg cardan joints or transition pieces are required.

Es sind daher Steckverbindungen mit Schnellauslösung bekannt. Solche Steckverbindungen weisen üblicherweise eine federbelastete Kugel an dem Vierkant auf, die in eine entsprechende Ausnehmung eines auf den Vierkant aufgesteckten Steckschlüsseleinsatzes o. dgl. greift und diesen in axialer Richtung auf dem Vierkant hält. Zum Lösen der Steckverbindung wird ein Auslöseknopf betätigt. Dadurch wird ein Mechanismus bewegt, der ein Hineindrücken der Kugel in den Vierkant gestattet. Die Verbindung kann dann durch leichtes Abziehen des Steckschlüsseleinsatzes von dem Werkzeug gelöst werden.There are therefore known connectors with quick release. Such connectors usually have a spring-loaded ball on the square, which engages in a corresponding recess of a plugged onto the square socket wrench insert o. The like. And this holds in the axial direction on the square. To release the connector, a release button is pressed. This moves a mechanism that allows the ball to be pushed into the square. The connection can then be released by slightly removing the socket wrench from the tool.

Die DE 201 19 262 U1 zeigt eine solche Steckverbindung mit Schnellauslösung. An einem Grundkörper ist ein Mehrkant vorgesehen. Der Mehrkant weist eine radiale Bohrung in einer der Kantenflächen auf. In der Bohrung sitzt eine Kugel. In einem Längskanal des Mehrkants ist ein Stab angeordnet, der eine Ausnehmung aufweist. Die Kugel kann teilweise von der Ausnehmung aufgenommen werden. Sie ist dann vollständig in dem Mehrkant versenkt. Der Stab ist durch ein Auslöseglied um seine Achse zwischen zwei Drehlagen verdrehbar. In der einen Drehlage wird die Kugel in der Bohrung radial nach außen gedrückt, so daß sie eine Verriegelung der beiden Teile der Steckverbindung bewirkt. In der anderen Drehlage fluchtet die Ausnehmung mit der Bohrung, so daß die Kugel ausweichen kann und das Auseinanderziehen der Steckverbindung nicht behindert.The DE 201 19 262 U1 shows such a connector with quick release. On a main body a polygon is provided. The polygon has a radial bore in one of the edge surfaces. There is a ball in the hole. In a longitudinal channel of the polygon a rod is arranged, which has a recess. The ball can be partially absorbed by the recess. It is then completely sunk in the polygon. The rod is rotatable by a trigger member about its axis between two rotational positions. In one rotational position, the ball is pressed in the bore radially outward, so that it causes a locking of the two parts of the connector. In the other rotational position, the recess is aligned with the bore, so that the ball can dodge and does not hinder the pulling apart of the connector.

Die EP 0 747 174 B1 beschreibt eine Steckverbindung für eine Steckschlüsselverlängerung. In einem Längskanal eines Mehrkants ist ein Schieber beweglich geführt. Der Längskanal steht mit einer Querbohrung in Verbindung. In der Querbohrung sitzt eine Kugel. Der Schieber weist eine Vertiefung auf, welche in einer Position des Schiebers die Kugel aufzunehmen vermag. Der Schieber steht unter dem Einfluß einer Feder und kann durch einen in einer weiteren Querbohrung geführten Knopf über eine Schrägfläche gegen die Wirkung der Feder in eine Stellung verschoben werden, in welcher die Kugel von der Vertiefung aufgenommen wird.The EP 0 747 174 B1 describes a plug connection for a socket wrench extension. In a longitudinal channel of a polygon a slider is movably guided. The longitudinal channel communicates with a transverse bore. There is a ball in the cross hole. The slider has a recess which is able to receive the ball in a position of the slider. The slide is under the influence of a spring and can be moved by a guided in another transverse bore knob on an inclined surface against the action of the spring in a position in which the ball is received by the recess.

Die vorstehend beschriebenen bekannten Anordnungen erfordern komplizierte Teile und sind daher nur mit großem Aufwand zu fertigen.The known arrangements described above require complicated parts and therefore can only be produced with great effort.

Die EP 0 861 140 B1 beschreibt eine schnell auslösbare Kupplungsvorrichtung bei welcher in einer Längsbohrung eines Mehrkants ein Schieber geführt ist, der durch einen schwenkbar gelagerten Stellknopf gegen die Wirkung einer Feder axial verschiebbar ist. Der Schieber weist einen Abschnitt von geringerem Durchmesser auf. Dieser Abschnitt vermag in einer Stellung des Schiebers eine in einer Querbohrung sitzende Kugel aufzunehmen, wodurch die Verriegelung gelöst wird. Auch diese Anordnung ist konstruktiv und fertigungstechnisch sehr aufwendig.The EP 0 861 140 B1 describes a quickly releasable coupling device in which in a longitudinal bore of a polygonal a slider is guided, which is axially displaceable by a pivotally mounted knob against the action of a spring. The slider has a portion of smaller diameter. This section is able to receive a seated in a transverse bore ball in a position of the slide, whereby the lock is released. This arrangement is constructive and manufacturing technology very expensive.

Bei einer schnell auslösbaren Kupplungsvorrichtung nach der US 4,962,682 enthält ein Längskanal des Mehrkants eine Reihe von Kugeln, von denen die letzte in einem radialen Abschnitt dieses Kanals sitzt. Die Kugeln sind an einem federbelasteten Auslöseknopf abgestützt, so daß die letzte Kugel über die Fläche des Mehrkants hinausragt. Durch Niederdrücken des Auslöseknopfes gelangt eine Umfangsnut des Auslöseknopfes in den Bereich der Kugeln, so daß diese axial ausweichen können und die letzte Kugel radial ausweicht.In a rapidly releasable coupling device according to the US 4,962,682 a longitudinal channel of the polygon contains a series of balls, the last of which sits in a radial section of this channel. The balls are supported on a spring-loaded release button, so that the last ball protrudes beyond the surface of the polygon. By depressing the trigger button enters a circumferential groove of the release button in the region of the balls, so that they can dodge axially and the last ball deflects radially.

Die DE 197 44 865 C2 betrifft eine rohrförmige Steckschlüsselverlängerung. Die Steckschlüsselverlängerung weist an einem Ende einen Vierkant und am gegenüberliegenden Ende eine Vierkantaufnahme auf. Zentral durch die rohrförmige Steckschlüsselverlängerung erstreckt sich eine Stange, die in einem Längskanal des Vierkants geführt ist. Die Stange weist in dem Längskanal ein sich verjüngendes Ende auf. In einer Querbohrung sitzt eine Kugel, welche durch das sich verjüngende Ende radial nach außen zur Verriegelung z.B. eines Steckschlüsseleinsatzes gedrückt wird, wenn die Stange in Richtung auf den Vierkant bewegt wird. Die Stange steht unter dem Einfluß einer Feder, welche die Stange in Richtung auf die Vierkantaufnahme zu bewegen trachtet. Wenn ein Vierkant, z.B. einer Knarre, in die Vierkantaufnahme eingesteckt wird, drückt er auf das in die Vierkantaufnahme ragende Ende der Stange und bewegt diese gegen die Wirkung der Feder in eine Stellung, in welcher die Kugel über die Verjüngung radial nach außen gedrückt wird.The DE 197 44 865 C2 relates to a tubular socket wrench extension. The socket wrench extension has a square at one end and a square socket at the opposite end. Central through the tubular Socket extension extends a rod which is guided in a longitudinal channel of the square. The rod has a tapered end in the longitudinal channel. In a transverse bore sits a ball, which is pressed by the tapered end radially outward for locking, for example, a socket wrench when the rod is moved in the direction of the square. The rod is under the influence of a spring, which strives to move the rod towards the square socket. When a square, such as a ratchet, is inserted into the square socket, it presses on the protruding into the square socket end of the rod and moves it against the action of the spring in a position in which the ball is pressed over the taper radially outward.

Die DE 197 58 493 C2 zeigt eine Steckschlüsselverlängerung mit einem Stellkörper, der in einer Längsbohrung eines Mehrkants verschiebbar geführt ist. Der Stellkörper hat zylindrische Grundform mit einem sich konisch verjüngenden Ende innerhalb des Längskanals. Eine in einer Querbohrung sitzende Kugel kann durch das konische Ende des Stellkörpers radial nach außen gedrückt werden. Das andere Ende des Stellkörpers ist von einem Kopf mit einer Planfläche gebildet. Eine Feder drückt den Stellkörper von der Kugel weg aus dem Mehrkant heraus. Der Stellkörper kann durch einen drehbar gelagerten Nocken gegen die Federwirkung vorgedrückt werden und schiebt dann über das konische Ende die Kugel in eine Riegelstellung.The DE 197 58 493 C2 shows a socket wrench extension with a control body, which is guided displaceably in a longitudinal bore of a polygon. The actuator body has a cylindrical basic shape with a conically tapered end within the longitudinal channel. A seated in a transverse bore ball can be pressed by the conical end of the actuator radially outward. The other end of the actuating body is formed by a head with a plane surface. A spring pushes the adjusting body away from the ball out of the polygon. The actuator can be pushed by a rotatably mounted cam against the spring action and then pushes over the conical end of the ball in a locked position.

In the shaft is transverse to the longitudinal bore a blind hole, which receives a so-called. Transfer ball.

Eine bewegliche Hülse umgibt den Schaft am Übergang zur Vierkantaufnahme. Im hinteren Teil der Hülse, befindet sich eine Feder. Im Bereich der Sacklochbohrung weist die Hülse auf der Innenseite eine Schräge auf Dadurch kann die Transferkugel beim Zurückziehen der Hülse aus der Sacklochbohrung gleiten und den Stellkörper freigeben, der sich in Richtung der hinteren Wand der Sacklochbohrung bewegt. Bei dieser Position kann die Rastkugel ohne Widerstand nach innen in die Querbohrung ausweichen und die Verriegelung.A movable sleeve surrounds the shaft at the transition to the square socket. In the back of the sleeve, there is a spring. In the area of the blind hole, the sleeve has a bevel on the inside. As a result, when the sleeve is withdrawn, the transfer ball can slide out of the blind bore and release the actuating body, which moves in the direction of the rear wall of the blind hole. In this position, the detent ball can escape without resistance inward into the transverse bore and the lock.

Zur Arretierung wird die Hülse nach hinten gezogen, der Steckschlüsseleinsatz aufgesteckt und die Hülse nach vorne geschoben. Dadurch drückt sich die Transferkugel in die Querbohrung hinein, verschiebt damit den Stellkörper nach vorne, der dann die Rastkugel durch die Querbohrung nach außen drückt und den Steckschlüsseleinsatz damit arretiert.To lock the sleeve is pulled back, the socket inserted and pushed the sleeve forward. As a result, the transfer ball presses into the transverse bore, thus displacing the adjusting body forward, which then pushes the detent ball through the transverse bore to the outside and thus locks the socket wrench insert.

Der Erfindung liegt die Aufgabe zugrunde, eine Kupplungsvorrichtung zur Verriegelung von Steckverbindungen mit einfach herstellbaren und daher kostengünstigen Bauteilen aufzubauen.The invention has for its object to build a coupling device for locking connectors with easy to manufacture and therefore cost-effective components.

Zu diesem Zweck ist bei einer Kupplungsvorrichtung der eingangs genannten Art vorgesehen, daß das Auslöseglied ein Rotationskörper mit einer Nockenfläche ist, wobei der Stellkörper mit seinem sich verjüngenden zweiten Ende an der Nockenfläche anliegt und das Auslöseglied (34) gegen die Wirkung einer Feder aus einer ersten Stellung, in welcher der Stellkörper durch die Nockenfläche in eine die Kugel in ihrer Verriegelungsstellung haltende Lage vorbewegt ist, in eine zweite Stellung bewegbar ist, in welcher der Stellkörper eine radiale Einwärtsbewegung der Kugel aus ihrer Verriegelungsstellung zuläßt.For this purpose, it is provided in a coupling device of the type mentioned that the trigger member is a rotary body with a cam surface, wherein the actuating body rests with its tapered second end of the cam surface and the trigger member (34) against the action of a spring from a first Position in which the actuating body is advanced by the cam surface in a position holding the ball in its locked position, in a second position is movable, in which the actuating body permits a radial inward movement of the ball from its locking position.

Damit ergibt sich eine sehr einfache, insbesondere einfach herzustellende und daher preisgünstige Konstruktion, die im Wesentlichen nur durch Drehteile und Bohrungen realisiert werden kann. Der Stellkörper wird unter dem Einfluß der Feder über die Nockenfläche vorgeschoben, so daß die Kugel in ihre Riegelposition gedrückt wird. Zum schnellen Lösen der Kupplung wird das Auslöseglied gegen die Wirkung der Feder eingedrückt. Die Nockenfläche gibt dann den Stellkörper frei, so daß dieser bei radialer Kraftausübung auf die Kugel ohne Gegenkraft ausweicht und ein radiales Eindrücken der Kugel, ebenfalls ohne Gegenkraft, gestattet. Wegen der geringen Kontaktflächen, die jeweils zwischen der Kugel und dem Stellkörper bzw. der Nockenfläche und Stellkörper vorliegt, wird die Reibung stark reduziert. Die Kugel berührt das sich verjüngende Ende des Stellkörpers streng genommen nur in einem Punkt. Die Nockenfläche berührt den Stellkörper lediglich auf einer Linie. Dadurch werden die Bewegungsabläufe insgesamt erheblich leichtgängiger. Auf diese Weise ist die Konstruktion auch nicht so anfällig gegen mögliche Verschmutzungen.This results in a very simple, in particular easy to manufacture and therefore inexpensive construction, which can be realized only by turning parts and holes substantially. The actuator is advanced under the influence of the spring over the cam surface, so that the ball is pressed into its locked position. For quick release of the clutch, the trigger member is pressed against the action of the spring. The cam surface then releases the actuating body, so that it deflects with radial force exerted on the ball without counterforce and a radial impressions of the ball, also without counterforce allowed. Because of the small contact surfaces, which is present in each case between the ball and the adjusting body or the cam surface and actuating body, the friction is greatly reduced. Strictly speaking, the ball only touches the tapered end of the actuator in one point. The cam surface touches the actuator body only on one line. As a result, the overall motion sequences are much smoother. In this way, the construction is not so susceptible to possible contamination.

Eine vorteilhafte Ausführung besteht darin, daß das sich verjüngende zweite Ende des Stellkörpers anschließend an die Verjüngung eine zur Bewegungsrichtung des Stellkörpers senkrechte Stirnfläche bildet und die Nockenfläche einen ersten zylindrischen Abschnitt aufweist, an welchem der Stellkörper in seiner ersten Stellung mit der Stirnfläche anliegt.An advantageous embodiment is that the tapered second end of the actuating body subsequent to the taper forms a perpendicular to the direction of movement of the actuating body end face and the cam surface has a first cylindrical portion on which the actuating body rests in its first position with the end face.

Damit ist der Stellkörper in der ersten Stellung, bei welcher sich die Kugel in ihrer Verriegelungsstellung befindet, gegen axiale Kräfte, die von der Kugel ausgeübt werden könnten, sicher abgestützt. Der Stellkörper befindet sich in einer definierten Stellung.Thus, the actuating body in the first position, in which the ball is in its locking position, against axial forces that could be exerted by the ball, safely supported. The actuator is in a defined position.

Es ist vorteilhaft, wenn die Nockenfläche einen zweiten zylindrischen Abschnitt aufweist, dessen Durchmesser geringer ist als der des ersten zylindrischen Abschnitts und an welchem der Stellkörper in seiner zweiten Stellung mit der Stirnfläche anliegt. Dann ist die Position des Stellkörpers auch in seiner zweiten Stellung, in welcher er eine Einwärtsbewegung der Kugel gestattet, genau festgelegt. Dadurch ist bei der ein Ausweichen der Kugel gestattenden Endstellung des Stellkörpers die Kugel durch das erste Ende des Stellkörpers in der Querbohrung gesichert. Die Kugel kann nicht in den Längskanal gedrückt werden.It is advantageous if the cam surface has a second cylindrical portion whose diameter is smaller than that of the first cylindrical portion and on which the actuating body rests in its second position with the end face. Then the position of the actuator is also in its second position, in which it allows an inward movement of the ball, precisely defined. This is at the one Dodge the ball gestattenden end position of the actuating body, the ball through the first end of the actuator secured in the transverse bore. The ball can not be pushed into the longitudinal channel.

Vorteilhafterweise ist zwischen dem ersten und dem zweiten zylindrischen Abschnitt der Nockenfläche ein konischer Abschnitt gebildet. Wenn das Auslöseglied niedergedrückt wird, dann gleitet die Stirnfläche des Stellkörpers von dem ersten zylindrischen Abschnitt ab. Der Stellkörper gleitet längs des konischen Abschnitts aus seiner ersten Stellung in seine zweite Stellung, in welcher die Stirnfläche schließlich an dem zweiten zylindrischen Abschnitt anliegt. Die Kugel wird freigegeben und die Verriegelung wird gelöst. Nach Loslassen des Auslösegliedes wird der Stellkörper unter dem Einfluß der auf das Auslöseglied wirkenden Feder durch den konischen Abschnitt der Nockenfläche wieder in seine erste Stellung vorgeschoben und rastet mit seiner Stirnfläche vor dem ersten zylindrischen Abschnitt ein.Advantageously, a conical section is formed between the first and second cylindrical portions of the cam surface. When the trigger member is depressed, the end face of the actuator slides off the first cylindrical portion. The actuating body slides along the conical portion from its first position to its second position, in which the end face is finally applied to the second cylindrical portion. The ball is released and the lock is released. After releasing the trigger member of the actuating body is pushed back under the influence of acting on the trigger member spring through the conical portion of the cam surface in its first position and locked with its end face in front of the first cylindrical portion.

An embodiment of the invention is explained below with reference to the accompanying drawings.
Fig. 1
shows in a section a portion of an extension according to the invention with quick release for plug tools in the locked state.
Fig. 2
shows in a section a portion of an extension according to the invention with quick release for insertion tools in the unlocked state.

In Fig. 1 wird im Schnitt ein Teilbereich einer erfindungsgemäßen Betätigungswerkzeugs oder Verbindungsteils, z.B. einer Verlängerung 10 mit Schnellverschluß 12 für Steckwerkzeuge dargestellt. Die Verlängerung 10 weist einen Grundkörper 14 auf. In dem Grundkörper 14 befindet sich an dem einen Ende ein axialer Längskanal 16 in Form einer Bohrung. Der axiale Längskanal 16 wird durch die Kantenflächen 18 eines Mehrkants 20 umschlossen. Eine als Sacklochbohrung ausgebildete Querbohrung 22 ist senkrecht zu dem axialen Längskanal 16 angeordnet und schneidet diesen an. In einer Querbohrung 24 der Kantfläche 18 des Mehrkants 20 ist eine Kugel 26 vorgesehen. Die Kugel 26 kann mit einem Stellkörper 28, der in dem Längskanal 16 vorgesehen ist, je nach Lage versenkt oder herausgeschoben werden. An der Querbohrung 24 sind bekannte Mittel zur Begrenzung der Auswärtsbewegung der Kugel 26 vorgesehen.In Fig. 1 is shown on average a portion of an operating tool or connection part according to the invention, for example an extension 10 with quick release 12 for plug-in tools. The extension 10 has a base body 14. In the base body 14 is located at one end an axial longitudinal channel 16 in the form of a bore. The axial longitudinal channel 16 is defined by the edge surfaces 18 of a Polygon 20 enclosed. A trained as a blind hole transverse bore 22 is perpendicular to the axial longitudinal channel 16 and cuts it. In a transverse bore 24 of the edge surface 18 of the polygon 20, a ball 26 is provided. The ball 26 can be sunk or pushed out with a control element 28 which is provided in the longitudinal channel 16, depending on the position. At the transverse bore 24 known means for limiting the outward movement of the ball 26 are provided.

Der Stellkörper 28 ist an seinen Enden 30, 32 jeweils konisch ausgebildet. Durch die konische Ausbildung des einen Endes 30 kann die Kugel 26 entsprechend der axialen Bewegung des Stellkörpers 28 kontinuierlich versenkt oder herausgeschoben werden. Das andere konische Ende 32 des Stellkörpers 28 liegt an einem als Drehteil ausgebildeten, hantelförmigen Auslöseglied 34 an.The adjusting body 28 is formed conically at its ends 30, 32. Due to the conical design of the one end 30, the ball 26 can be sunk continuously according to the axial movement of the adjusting body 28 or pushed out. The other conical end 32 of the actuating body 28 bears against a dumbbell-shaped triggering element 34 designed as a turned part.

Das Auslöseglied 34 ist hantelförmig mit zwei Endteilen 35 und 37 von zylindrischer Grundform mit einander zugewandten kegelstumpfförmigen Abschnitten 39 und 41 ausgebildet, die in der Querbohrung 22 geführt sind. Zwischen diesen Endteilen 35 und 37 ist eine Nockenfläche 43 gebildet. Diese Nockenfläche 43 besteht aus einem zylindrischen Abschnitt 44 von relativ großem Durchmesser, einem konischen Abschnitt 45 und einem zylindrischen Abschnitt 47 von relativ zu dem Abschnitt 44 kleinem Durchmesser. Der Kegelwinkel des konischen Endes 32 des Stellkörpers 28 ist komplementär zu dem Kegelwinkel des konischen Abschnitts 45 der Nockenfläche 43. Das Auslöseglied 34 ragt leicht aus der Querbohrung 22 heraus und bildet einem Druckknopf 36. Das Betätigungsglied 34 ist durch eine Feder 38 vorgespannt. Die Feder 38 sitzt zwischen dem Endteil des Auslösegliedes 34 und dem Grund der Querbohrung 22. Die Feder 38 sucht das Auslöseglied 34 nach oben in den Figuren in die in Fig.1 dargestellte Lage zu drücken. Das Auslöseglied kann durch Druck auf den Druckknopf 36 gegen die Wirkung der Feder 38 nach unten in die in Fig.2 dargestellte Lage verschoben werden.The trigger member 34 is dumbbell-shaped with two end portions 35 and 37 of cylindrical basic shape with mutually facing frusto-conical portions 39 and 41 which are guided in the transverse bore 22. Between these end portions 35 and 37, a cam surface 43 is formed. This cam surface 43 consists of a cylindrical portion 44 of relatively large diameter, a conical portion 45 and a cylindrical portion 47 of relative to the small diameter portion 44. The cone angle of the conical end 32 of the actuating body 28 is complementary to the cone angle of the conical portion 45 of the cam surface 43. The trigger member 34 projects slightly out of the transverse bore 22 and forms a push button 36. The actuator 34 is biased by a spring 38. The spring 38 is seated between the end portion of the trigger member 34 and the bottom of the transverse bore 22. The spring 38 seeks the trigger member 34 upward in the figures in the Fig.1 to press shown position. The trigger member can by pressing the push button 36 against the action of the spring 38 down in the in Fig.2 be shifted position shown.

Der Stellkörper 28 hat zylindrische Grundform. Das in den Figuren linke Ende 32 des Stellkörpers 28 ist kegelstumpfförmig und bildet eine zur Achse des Stellkörpers 28 senkrechte, ebene Stirnfläche 48, nämlich die kleinere Fläche des Kegelstumpfes. Das in den Figuren rechte Ende 30 des Stellkörpers ist ebenfalls kegelstumpfförmig.The actuating body 28 has a cylindrical basic shape. The left end in the figures 32 of the actuating body 28 is frustoconical and forms a plane perpendicular to the axis of the actuating body 28, flat end face 48, namely the smaller surface of the truncated cone. The right end in the figures 30 of the actuating body is also frustoconical.

In der Position von Fig.1 ist das Auslöseglied 34 von der Feder 38 nach oben gedrückt. Der Stellkörper 28 liegt mit seiner ebenen Stirnfläche 48 an dem zylindrischen Abschnitt 44 des Auslösegliedes an. Der Stellkörper 28 ist in seiner rechten Endstellung, in welcher er über das kegelstumpfförmige Ende 30 die Kugel 26 in der Querbohrung 24 nach außen in ihre Verriegelungsstellung drückt. Der Stellkörper 28 nimmt dabei eine definierte Stellung ein. Es ist nicht möglich, den Stellkörper 28 durch Druck auf die Kugel 26 nach links in den Figuren zu verschieben.In the position of Fig.1 the trigger member 34 is pushed by the spring 38 upwards. The adjusting body 28 rests with its flat end face 48 on the cylindrical portion 44 of the trigger member. The actuating body 28 is in its right end position in which he pushes the ball 26 in the transverse bore 24 outwardly into its locking position via the frusto-conical end 30. The actuator body 28 assumes a defined position. It is not possible to move the actuator 28 by pressing the ball 26 to the left in the figures.

Bei Niederdrücken des Auslösegliedes 34 gleitet die Stirnfläche von dem zylindrischen Abschnitt 44 ab. Dadurch wird der Stellkörper 28 freigegeben. Der Stellkörper kann sich längs des konischen Abschnitts 45 nach links in den Figuren bewegen, bis der Stellkörper an dem zylindrischen Abschnitt 47 von kleinerem Durchmesser zur Anlage kommt. Bei dieser Position des Stellkörpers, die in Fig.2 dargestellt ist, kann die Kugel 26 ohne wesentlichen Widerstand nach innen in die Querbohrung 24 ausweichen. Damit ist die Verriegelung gelöst. Das auf den Mehrkant 20 aufgesetzte Teil, z.B. ein Steckschlüsseleinsatz, kann ohne Kraftaufwand abgezogen werden. Auch die Position des Stellkörpers 28 in Fig.2 ist genau definiert durch Anlage der Stirnfläche 48 an dem zylindrischen Abschnitt 47. In dieser Position ist die Kugel 26 in der Querbohrung gesichert durch das Ende 30 des Stellkörpers 28. Die Kugel 26 kann nicht einwärts in den Längskanal gedrückt werden. Auch hier ist es nicht möglich, durch Druck auf die Kugel 26 den Stellkörper 28 weiter nach links zu verschieben.Upon depression of the trigger member 34, the end face slides off the cylindrical portion 44. As a result, the adjusting body 28 is released. The actuator can move along the conical portion 45 to the left in the figures until the actuator comes to rest on the cylindrical portion 47 of smaller diameter. In this position of the actuator, which in Fig.2 is shown, the ball 26 can escape without substantial resistance inwardly into the transverse bore 24. This unlocks the lock. The patch on the polygon 20 part, such as a socket wrench, can be deducted without effort. Also, the position of the actuator 28 in Fig.2 is precisely defined by abutment of the end surface 48 on the cylindrical portion 47. In this position, the ball 26 is secured in the transverse bore through the end 30 of the actuator body 28. The ball 26 can not be pushed inwardly into the longitudinal channel. Again, it is not possible by pressure on the ball 26, the actuator 28 to move further to the left.

Der Längskanal 16 ist durch einen Stopfen 50 an seinem Ende abgeschlossen.The longitudinal channel 16 is closed by a plug 50 at its end.
