Description

Die vorliegende Erfindung betrifft eine Klinkenbuchse für Verstärker, Lautsprecherboxen, elektrische Musikinstrumente u. dgl., die einen Buchsenteil zur Einführung und Halterung eines elektrischen Steckelementes und mindestens zwei mit dem Steckelement in Eingriff bringbare elektrische Kontakte aufweist.The present invention relates to a jack socket for amplifiers, speakers, electrical musical instruments and. Like., Which has a socket part for the insertion and mounting of an electrical plug element and at least two electrical contacts which can be brought into engagement with the plug element.

Es besteht die Problematik, derartige Geräte gegen unbefugte Benutzung zu schützen, da diese in Ausstellräumen, Tonstudios u. dgl. oft frei zugänglich sind. So können die Geräte über geeignete Anschlüsse an Stromquellen durch Einführung von Steckelementen in die an den Geräten vorgesehenen Klinkenbuchsen ohne weiteres betriebsbereit gemacht werden.There is the problem of protecting such devices against unauthorized use, since they are used in showrooms, recording studios and the like. The like. are often freely accessible. The devices can be made ready for operation by suitable connections to power sources by inserting plug elements into the jack sockets provided on the devices.

Klinkenbuchsen der eingangs beschriebenen Art befinden sich in vielen Ausführungsformen im Gebrauch. Sie weisen in der Regel einen Buchsenteil sowie einen sich an den Buchsenteil anschließenden Gehäuseteil auf. Der Buchsenteil besitzt eine runde Innenbohrung zur Aufnahme eines runden elektrischen Steckelementes, das im Gehäuseteil mit zwei Kontaktklemmen bei Monosteckern und drei Kontaktklemmen bei Stereosteckern in Kontakt tritt, wobei durch eine entsprechende Vertiefung am Steckelement bzw. vorspringende Abschnitte an den Kontaktklemmen eine Verrastung zwischen Steckelement und Kontaktklemmen erreicht wird. Die Kontaktklemmen stehen mit geeigneten Leiterabschnitten in Verbindung, die aus der Klinkenbuchse herausführen. Klinkenbuchsen ohne entsprechenden Gehäuseteil sind ebenfalls bekannt.Jack sockets of the type described in the introduction are in use in many embodiments. They usually have a socket part and a housing part adjoining the socket part. The socket part has a round inner hole for receiving a round electrical plug element, which comes into contact in the housing part with two contact clamps for mono plugs and three contact clamps for stereo plugs, with a corresponding recess on the plug element or projecting sections on the contact clamps for locking between the plug element and contact terminals is reached. The contact terminals are connected to suitable conductor sections that lead out of the jack socket. Jack sockets without a corresponding housing part are also known.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Klinkenbuchse der eingangs beschriebenen Art zu schaffen, die gegen unbefugte Benutzung geschützt ist.The present invention has for its object to provide a jack socket of the type described above, which is protected against unauthorized use.

Die Aufgabe wird erfindungsgemäß bei einer Klinkenbuchse der angegebenen Art dadurch gelöst, daß sie ein in den Buchsenteil eingeführtes verriegelbares und entfernbares Blockierungselement besitzt, das ein unbefugtes Einführen eines elektrischen Steckelementes in die Buchse verhindert.The object is achieved with a jack socket of the specified type in that it has a lockable and removable blocking element inserted into the socket part, which prevents unauthorized insertion of an electrical plug element into the socket.

Die erfindungsgemäße Lösung sieht somit vor, die entsprechende Klinkenbuchse durch ein eingeführtes Element so zu blockieren, daß ein entsprechendes elektrisches Steckelement nicht mehr einführbar ist. Das zugehörige Gerät, an dem die Klinkenbuchse angeordnet ist, kann somit nicht mehr an eine elektrische Stromquelle bzw. an ein weiteres Gerät angeschlossen werden, so daß das Gerät von einer unbefugten Person nicht mehr in Betrieb genommen werden kann. Dies trifft inbesondere für elektrische Musikinstrumente zu, die hierdurch gegen unbefugtes Benutzen geschützt werden können. Das in den Buchsenteil eingeführte verriegelbare und entfernbare Blockierungselement kann von einer befugten Person entriegelt und danach aus dem Buchsenteil entfernt werden, so daß ein entsprechendes Steckelement von einer befugten Person wieder in die Klinkenbuchse eingeführt werden kann. Es versteht sich, daß nur befugte Personen geeignete Mittel zum Entriegeln des Blockierungselementes besitzen.The solution according to the invention thus provides for the corresponding jack socket to be blocked by an inserted element in such a way that a corresponding electrical plug element can no longer be inserted. The associated device on which the jack socket is arranged can thus no longer be connected to an electrical power source or to another device, so that the device can no longer be put into operation by an unauthorized person. This applies in particular to electrical musical instruments, which can thereby be protected against unauthorized use. The lockable and removable blocking element inserted into the socket part can be unlocked by an authorized person and then removed from the socket part, so that a corresponding plug element can be reinserted into the jack socket by an authorized person. It is understood that only authorized persons have suitable means for unlocking the blocking element.

Vorzugsweise ist das Blockierungselement mittels eines Schlüssels verriegelbar und entriegelbar. Um das mit der Klinkenbuchse versehene Gerät vor unbefugter Benutzung zu schützen, wird das Blockierungselement in den Buchsenteil eingeführt und dort durch Betätigung des Schlüssels verriegelt. Wenn das Gerät wieder zur Benutzung freigegeben werden soll, erfolgt durch erneute Betätigung des Schlüssels eine Entriegelung, wonach das Blockierungselement aus dem Buchsenteil gezogen werden kann.The blocking element can preferably be locked and unlocked by means of a key. In order to protect the device provided with the jack socket from unauthorized use, the blocking element is inserted into the socket part and locked there by actuating the key. If the device is to be released for use again, the key is unlocked again, after which the blocking element can be pulled out of the socket part.

In Weiterbildung der Erfindung weist das Blockierungselement ein Betätigungselement und ein vom Betätigungselement betätigbares Verriegelungselement auf, das sich im betätigten Zustand bis in eine Position radial außerhalb der Bohrung des Buchsenteiles erstreckt und dadurch ein Herausziehen des Blockierungselementes verhindert. Die mit dem Blockierungselement erzielbare Verriegelung kommt daher dadurch zustande, daß durch Betätigung des Betätigungselementes das Verriegelungselement in eine Position radial außerhalb der Bohrung des Buchsenteiles gebracht wird, die ein Herausziehen des Blockierungselementes aus dem Buchsenteil verhindert. Wird daher mit Hilfe des Schlüssels das Betätigungselement betätigt, so wandert das Verriegelungselement in die Position radial außerhalb der Bohrung des Buchsenteiles, und der verriegelte Zustand des Blockierungselementes ist erreicht. Der Schlüssel läßt sich dann abziehen, so daß die Klinkenbuchse für Unbefugte blockiert ist. Durch erneutes Einstecken des Schlüssels und Rückwärtsdrehen desselben wird das Betätigungselement wieder in seine Ausgangslage zurückgeführt, wodurch das Verriegelungselement in seine Postion innerhalb der Bohrung des Buchsenteiles gelangt. Das Blockierungselement kann jetzt wieder aus der Klinkenbuchse herausgezogen werden.In a further development of the invention, the blocking element has an actuating element and a locking element which can be actuated by the actuating element and which, in the actuated state, extends to a position radially outside the bore of the socket part and thereby prevents the blocking element from being pulled out. The locking which can be achieved with the blocking element therefore comes about in that, by actuating the actuating element, the locking element is brought into a position radially outside the bore of the socket part, which prevents the blocking element from being pulled out of the socket part. Therefore, if the actuating element is actuated with the aid of the key, the locking element moves into the position radially outside the bore of the socket part, and the locked state of the blocking element is reached. The key can then be removed so that the jack socket is blocked for unauthorized persons. By reinserting the key and turning it backwards, the actuating element is returned to its starting position, as a result of which the locking element comes into its position within the bore of the socket part. The blocking element can now be pulled out of the jack socket.

Es versteht sich, daß zur Betätigung des Betätigungselementes nicht unbedingt ein Drehvorgang eines Schlüssels erforderlich ist; die Betätigung kann beispielsweise auch das Einschieben eines Schlüssels oder eines vergleichbaren Elementen erfolgen. Die entsprechende Entriegelung erfolgt dabei über das Herausziehen des Schlüssels.It is understood that a turning operation of a key is not absolutely necessary to actuate the actuating element; the For example, actuation can also include the insertion of a key or a comparable element. The corresponding unlocking takes place by pulling out the key.

Wichtig ist, daß das Verriegelungselement so weit radial aus dem Buchsenteil herausbewegt wird, daß ein Herausziehen des Blockierungselementes durch bestimmte Manipulationen von Unbefugten nicht möglich ist. Da bei derartigen Klinkenbuchsen der eigentliche Buchsenteil mit entsprechender Bohrung relativ kurz ist und sich dahinter das Gehäuse mit den Steckelementen befindet, kann das Verriegelungselement hinter der Bohrung des Buchsenteiles im Gehäuses radial nach außen bewegt werden, so daß es beim Versuch des Herausziehens des Blockierungselementes gegen die zwischen Gehäuse und Bohrung gebildete Stufe stößt und damit ein Herausziehen unmöglich macht.It is important that the locking element is moved so far radially out of the socket part that the blocking element cannot be pulled out by certain manipulations by unauthorized persons. Since in such jacks the actual socket part with a corresponding bore is relatively short and behind it is the housing with the plug-in elements, the locking element behind the bore of the socket part in the housing can be moved radially outwards, so that it is attempted to pull out the blocking element against the step formed between the housing and the bore, making it impossible to pull it out.

Bei einer besonders bevorzugten Ausführungsform der Erfindung ist das Betätigungselement am Zylinder eines mit dem Schlüssel betätigbaren Schlosses angeordnet und durch Schlüsseldrehung von einer Ausgangsposition in eine Betätigungsposition drehbar, während das Verriegelungselement am Schloßgehäuse angeordnet ist. Hierbei wird durch Drehen des Schlüssels im Schloß der Schloßzylinder und damit das Betätigungselement in die Betätigungsposition gedreht, in der das Verriegelungselement, das am Schloßgehäuse angeordnet ist, radial nach außen bewegt wird. Zum Entriegeln des Blockierungselementes wird der Schlüssel in der umgekehrten Richtung gedreht.In a particularly preferred embodiment of the invention, the actuating element is arranged on the cylinder of a lock which can be actuated with the key and can be rotated by turning the key from an initial position into an actuating position, while the locking element is arranged on the lock housing. Here, by turning the key in the lock, the lock cylinder and thus the actuating element is rotated into the actuating position in which the locking element, which is arranged on the lock housing, is moved radially outward. To unlock the blocking element, the key is turned in the opposite direction.

In Weiterbildung der Erfindung ist das Verriegelungselement als vom Schloßgehäuse ausgehendes und zum zumindest teilweise aufweitbares Hülsenelement ausgebildet, in dem sich das stabförmige Betätigungselement befindet. Die Aufweitung des Hülsenelementes erfolgt dabei vorzugsweise über eine Drehung des Betätigungselementes; sie kann jedoch beispielsweise auch über die Einführung des Betätigungselementes in das Hülsenelement erfolgen. So kann das Verriegelungselement beispielsweise eine abbiegbare bzw. ausbiegbare Lasche umfassen, die durch das Betätigungselement abgebogen bzw. ausgebogen und damit in eine Position radial außerhalb der Bohrung des Buchsenteiles gebracht wird.In a further development of the invention, the locking element is designed as a sleeve element starting from the lock housing and at least partially expandable, in which the rod-shaped actuating element is located. The expansion of the sleeve element takes place preferably via a rotation of the actuating element; however, it can also be done, for example, by inserting the actuating element into the sleeve element. For example, the locking element can comprise a bendable or bendable tab, which is bent or bent out by the actuating element and thus brought into a position radially outside the bore of the socket part.

Um das Verriegelungselement in die radial äußere Position (Spreizposition) zu bringen, weist das Betätigungselement und/oder das Verriegelungselement zweckmäßigerweise eine entsprechende Verdickung auf, durch deren Kontakt mit dem Verriegelungselement bzw. Betätigungselement das Verriegelungselement radial nach außen bewegt wird. Durch umgekehrte Betätigung des Betätigungselementes wird die Verdickung wieder in eine Position bewegt, in der sie das Verriegelungselement nicht mehr nach außen bewegt bzw. ausbiegt, durchbiegt oder spreizt, so daß ein Herausziehen des Blockierungselementes aus der Klinkenbuchse möglich ist.In order to bring the locking element into the radially outer position (spreading position), the actuating element and / or the locking element expediently has a corresponding thickening, by means of whose contact with the locking element or actuating element the locking element is moved radially outward. By reverse actuation of the actuating element, the thickening is again moved into a position in which it no longer moves or bends, bends or spreads the locking element outward, so that the blocking element can be pulled out of the jack socket.

Das erfindungsgemäß ausgebildete Blockierungselement ist im verriegelten Zustand vorzugsweise nur teilweise in die Klinkenbuchse eingeführt; es ist vielmehr im wesentlichen auf diese aufgesetzt. Hierdurch wird eine besonders einfache und bequeme Betätigung des Blockierungselementes erreicht. Das Schloßgehäuse befindet sich dabei vorzugsweise außerhalb des Buchsenteiles und stößt mit einem Ende gegen das vordere Buchsenteilende, während das Verriegelungs- und das Betätigungselement in den Buchsenteil eingeführt sind und sich durch diesen hindurch bis in das Gehäuse (wenn vorhanden) erstrecken.The blocking element designed according to the invention is preferably only partially inserted into the jack socket in the locked state; rather, it is essentially based on this. A particularly simple and convenient actuation of the blocking element is hereby achieved. The lock housing is preferably located outside the socket part and abuts one end against the front socket part end, while the locking and the actuating element are inserted into the socket part and extend through this into the housing (if present).

Bei einer weiteren Ausführungsform der Erfindung sind das Betätigungselement und Verriegelungselement als einziges Element ausgebildet und weisen ein drehbares längliches Element auf, an dessen vorderem Ende ein hinter einen vorspringenden Abschnitt des Klinkenbuchse drehbarer Blockierabschnitt ausgebildet ist. Die Betätigung des länglichen Elementes erfolgt vorzugsweise ebenfalls über einen Schlüssel, der in ein geeignetes Zylinderschloß gesteckt wird. Durch Drehen des Schloßzylinders wird das längliche Element mitgedreht, so daß der Blockierabschnitt in seine einen vorspringenden Abschnitt der Klinkenbuchse hintergreifende Blockierstellung gerät. Zum Lösen des Blockierungselementes erfolgt der umgekehrte Vorgang, d.h. der Schlüssel wird in die entgegengesetzte Richtung gedreht, wodurch der Blockierabschnitt aus seiner Blockierstellung herausgedreht wird. In dieser Ausgangsstellung des Blockierabschnitts kann das Blockierungselement wieder aus der Klinkenbuchse herausgezogen werden.In a further embodiment of the invention, the actuating element and locking element are designed as a single element and have a rotatable elongate element, on the latter a blocking section rotatable behind a projecting section of the jack socket is formed at the front end. The elongated element is preferably also actuated using a key which is inserted into a suitable cylinder lock. By turning the lock cylinder, the elongated element is rotated, so that the blocking section comes into its blocking position engaging behind a projecting section of the jack socket. The procedure for reversing the blocking element is reversed, ie the key is turned in the opposite direction, whereby the blocking section is unscrewed from its blocking position. In this starting position of the blocking section, the blocking element can be pulled out of the jack socket again.

Das längliche Element ist vorzugsweise durch einen in die Klinkenbuchse einsetzbaren Tubus geführt. Der Tubus stellt sicher, daß das Blockierungselement eine fixierte zentrische Lage in der Klinkenbuchse einnimmt, so daß der Blockierabschnitt automatisch in die richtige Lage gerät. Dieser Blockierabschnitt ist vorzugsweise als exzentrisch am vorderen Ende des länglichen Elementes angeordnete Scheibe ausgebildet. In der nicht blockierenden Stellung nimmt die Scheibe eine etwa mittige Lage in bezug auf den Tubus ein und wird aus dieser Stellung zum Verriegeln herausgedreht. Es versteht sich, daß hierbei das längliche Element in bezug auf den Tubus und den Schloßzylinder exzentrisch angeordnet ist.The elongated element is preferably guided through a tube that can be inserted into the jack socket. The tube ensures that the blocking element assumes a fixed central position in the jack socket, so that the blocking section automatically comes into the correct position. This blocking section is preferably designed as an eccentrically arranged disc at the front end of the elongate element. In the non-blocking position, the disk assumes an approximately central position with respect to the tube and is rotated out of this position for locking. It is understood that the elongate element is arranged eccentrically with respect to the tube and the lock cylinder.

Die in Figur 1 im vertikalen Längsschnitt dargestellte Klinkenbuchse 1 besitzt ein etwa rechteckförmiges Gehäuse 3 aus Kunststoff und einen sich von diesem aus in der Figur nach rechts erstreckenden, mit einem Außengewinde versehenen Buchsenteil 2, der ebenfalls aus Kunststoff besteht. Der Buchsenteil weist in seinem Inneren eine im Schnitt kreisförmige Bohrung auf, die metallisch ausgekleidet ist. In diese Bohrung wird ein übliches elektrisches Steckelement (nicht gezeigt) eingeführt, das einen entsprechenden, im Schnitt kreisförmigen Abschnitt besitzt, der an die Bohrung des Buchsenteiles 2 angepaßt ist und im eingesteckten Zustand des Steckelementes von dieser aufgenommen wird. Am vorderen Ende besitzt das Steckelement ein Spitze und kurz hinter dieser eine Ringnut. Beim Einsetzen des Steckelementes in die Klinkenbuchse 1 werden zwei im Gehäuse 3 angeordnete, schräg nach innen verlaufende metallische Kontaktklemmen 5 radial nach außen gebogen und schnellen aufgrund ihrer Federwirkung in die am Steckelement vorgesehene Nut zurück, so daß einerseits das Steckelement in der Klinkenbuchse verrastet und andererseits eine elektrische Leitung zwischen Steckelement und Kontaktklemmen 5 hergestellt wird. Beim Herausziehen des Steckelementes wird der von den Kontaktklemmen 5 ausgeübte Widerstand überwunden, wobei diese in ihre Ausgangslage zurückkehren. Die Kontaktklemmen 5 stehen über geeignete Metallstege mit vom Gehäuse 3 vorstehenden Anschlußklemmen 6 in Verbindung.The jack 1 shown in vertical longitudinal section in FIG. 1 has an approximately rectangular housing 3 made of plastic and a socket part 2 which extends to the right in the figure and is provided with an external thread and which is also made of plastic. The inside of the socket part has a circular bore in section, which is lined with metal. A conventional electrical plug-in element (not shown) is introduced into this bore, which has a corresponding section which is circular in section and which is adapted to the bore of the socket part 2 and which is inserted Condition of the plug element is recorded by this. The plug element has a tip at the front end and an annular groove just behind it. When inserting the plug element into the jack socket 1, two metallic contact terminals 5 arranged in the housing 3, which run obliquely inwards, are bent radially outwards and snap back due to their spring action into the groove provided on the plug element, so that on the one hand the plug element latches in the jack socket and on the other hand an electrical line between the plug element and contact terminals 5 is produced. When the plug element is pulled out, the resistance exerted by the contact terminals 5 is overcome, and these return to their starting position. The contact terminals 5 are connected via suitable metal webs to the connection terminals 6 projecting from the housing 3.

Die Figuren 2 und 3 zeigen den schematischen Aufbau einer ersten Ausführungsform eines Blockierungselementes 4, das in die Klinkenbuchse einführbar ist, wenn sich in dieser kein Steckelement befindet, um die Buchse vor einer unbefugten Benutzung zu schützen. Bei dieser Ausführungsform ist das Blockierungselement 4 schloßförmig ausgebildet und umfaßt ein etwa zylindrisches Schloßgehäuse 7, in dem ein Schloßzylinder 8 drehbar angeordnet ist. Die Betätigung des Schloßzylinders erfolgt über einen Schlüssel 9, der in eine geeignete Schlüsselöffnung im Schloßzylinder einführbar ist. Wenn sich der Schlüsselbart im Schloßzylinder befindet, kann durch Drehen des Schlüssels der Schloßzylinder und ein in Verlängerung desselben angeordnetes und mit dem Schloßzylinder verbundenes stabförmiges Betätigungselement 11 gedreht werden. Das Betätigungselement 11 erstreckt sich durch eine vordere Öffnung im Schloßgehäuse 7 und ist von einem am Schloßgehäuse 7 befestigten hülsenförmigen Verriegelungselement 10 umgeben. Das hülsenförmige Verriegelungselement 10 ist in seinem in der Figur linken Endabschnitt geschlitzt. Der dadurch entstehende untere Teil des Verriegelungselementes ist kürzer ausgebildet als der zugehörige obere Teil. In den dadurch gebildeten Freiraum hinein erstreckt sich eine Verdickung 12 am vorderen Ende des stabförmigen Betätigungselementes.FIGS. 2 and 3 show the schematic structure of a first embodiment of a blocking element 4 which can be inserted into the jack socket if there is no plug element in it in order to protect the socket against unauthorized use. In this embodiment, the blocking element 4 is lock-shaped and comprises an approximately cylindrical lock housing 7, in which a lock cylinder 8 is rotatably arranged. The lock cylinder is actuated using a key 9 which can be inserted into a suitable key opening in the lock cylinder. If the key bit is in the lock cylinder, the lock cylinder and a rod-shaped actuating element 11 arranged in an extension thereof and connected to the lock cylinder can be rotated by turning the key. The actuating element 11 extends through a front opening in the lock housing 7 and is surrounded by a sleeve-shaped locking element 10 fastened to the lock housing 7. The sleeve-shaped locking element 10 is in its left in the figure End section slotted. The resulting lower part of the locking element is shorter than the associated upper part. A thickening 12 extends into the free space formed thereby at the front end of the rod-shaped actuating element.

Figur 3 zeigt, daß durch Drehung des Schlüssels der Schloßzylinder und damit das stabförmige Betätigungselement 11 gedreht wird. Hierdurch gelangt die Verdickung 12 in eine obere Lage und preßt dadurch den oberen Teil des federnd ausgebildeten hülsenförmigen Verjüngungselementes 10 nach oben. Wie Figur 1 zeigt, befindet sich in dieser Lage der obere Teil des Verjüngungselementes 10 in einer Position radial außerhalb von der Bohrung des Buchsenteiles 2, so daß sich das Blockierungselement 4 insgesamt nicht mehr ohne Zurückdrehen des Schloßzylinders aus der Klinkenbuchse entfernen läßt.Figure 3 shows that the lock cylinder and thus the rod-shaped actuating element 11 is rotated by turning the key. As a result, the thickening 12 reaches an upper position and thereby presses the upper part of the resilient, sleeve-shaped tapering element 10 upwards. As FIG. 1 shows, in this position the upper part of the tapering element 10 is in a position radially outside of the bore of the socket part 2, so that the blocking element 4 can no longer be removed from the jack socket without turning back the lock cylinder.

Figur 4 zeigt eine weitere Ausführungsform eines Blockierungselementes 4. Dieses besitzt, abgesehen vom Betätigungselement und Verriegelungselement, den gleichen Aufbau wie das in den Figuren 1 bis 3 gezeigte Blockierungselement. Auf eine erneute Beschreibung von identischen Teilen wird daher verzichtet. Die Funktionsweise ist ebenfalls entsprechend. Hierbei weist das stabförmige Betätigungselement 20 in seinem vorderen Abschnitt eine Ausnehmung 23 auf, in der im nicht betätigten Zustand eine Verdickung 22 eines hülsenförmigen Verriegelungselementes 21 ruht. Dieses hülsenförmige Verriegelungselement 21 weist ebenfalls wie bei der Ausführungsform der Figuren 1 bis 3 einen Schlitz in seinem vorderen Bereich auf, wodurch ein federnder ausbiegbarer Abschnitt entsteht. Durch Drehen des Schlüssels 9 mit dem zugehörigen Schloßzylinder 8 wird das Betätigungselement 20 um 1800 gedreht, so daß die Verdickung 22 aus der Ausnehmung 23 herauswandert und nunmehr gegen die glatte entgegengesetzte Fläche des Betätigungselementes 20 zu liegen kommt. Hierdurch wird der obere Abschnitt des Verriegelungselementes 21 ausgebogen, und zwar wiederum bis in eine Position radial außerhalb der Bohrung des Buchsenteiles, so daß auch bei dieser Ausführungsform in dieser Stellung ein Herausziehen des Blockierungselementes 4 aus der Klinkenbuchse nicht möglich ist.FIG. 4 shows a further embodiment of a blocking element 4. Apart from the actuating element and locking element, this has the same structure as the blocking element shown in FIGS. 1 to 3. A description of identical parts is therefore omitted. The mode of operation is also corresponding. Here, the rod-shaped actuating element 20 has a recess 23 in its front section, in which a thickened portion 22 of a sleeve-shaped locking element 21 rests in the non-actuated state. As in the embodiment of FIGS. 1 to 3, this sleeve-shaped locking element 21 also has a slot in its front area, as a result of which a resilient, bendable section is produced. By turning the key 9 with the associated lock cylinder 8, the actuating element 20 is rotated by 1800 so that the thickening 22 migrates out of the recess 23 and now lies against the smooth opposite surface of the actuating element 20 is coming. As a result, the upper section of the locking element 21 is bent out, again into a position radially outside the bore of the socket part, so that in this embodiment it is also not possible to pull the blocking element 4 out of the jack socket in this position.

Figur 5 zeigt eine weitere Ausführungsform der Erfindung, wobei hier ebenfalls nur das Blockierungselement ohne zugehörige Klinkenbuchse dargestellt ist. Bei dieser Ausführungsform besitzt das Blockierungselement 30 ein geeignetes Zylinderschloß mit Schloßzylinder, das in bekannter Weise über einen Schlüssel 9 betätigbar ist. Durch Drehen des Schlüssels 9 und damit des Schloßzylinders wird ein mit dem Schloßzylinder verbundenes, daran exzentrisch angeordnetes längliches Element 32 gedreht, an dessen vorderem Ende ein Blockierungsabschnitt 33 in der Form einer wiederum exzentrisch am länglichen Element angeordneten Scheibe angeordnet ist. Das längliche Element 32 erstreckt sich durch einen mittig am Schloß angeordneten Tubus 31, der als Führungs- und Fixierelement des Blockierungselementes in der Klinkenbuchse dient.FIG. 5 shows a further embodiment of the invention, in which case only the blocking element is also shown without an associated jack socket. In this embodiment, the blocking element 30 has a suitable cylinder lock with a lock cylinder which can be actuated in a known manner using a key 9. By turning the key 9 and thus the lock cylinder, an elongated element 32 connected to the lock cylinder and eccentrically arranged thereon is rotated, at the front end of which a blocking section 33 in the form of a disc, which is in turn eccentrically arranged on the elongated element, is arranged. The elongated element 32 extends through a tube 31 arranged in the middle of the lock, which serves as a guiding and fixing element of the blocking element in the jack socket.

Die linke Darstellung in Figur 5 zeigt das Blockierungselement im entriegelten Zustand. In diesem Zustand wird das Blockierungselement in die Klinkenbuchse eingeführt, wobei der Tubus 31 mit entsprechenden Abschnitten der Klinkenbuchse in Anlage kommt. Soll die Klinkenbuchse nunmehr verriegelt werden, so wird der Schlüssel 9 gedreht, wodurch der scheibenförmige Blockierabschnitt 33 in die in der rechten Darstellung der Figur 5 gezeigte Lage gerät, in der er einen entsprechenden nach innen vorstehenden Abschnitt der Klinkenbuchse hintergreift. Wird der Schlüssel nunmehr abgezogen, so kann das Blockierungselement nicht mehr aus der Klinkenbuchse entfernt werden. Zum Entfernen des Blockierungselementes findet der umgekehrte Vorgang statt, d.h. der Schlüssel wird in die entgegengesetzte Richtung gedreht, wodurch der scheibenförmige Blockierabschnitt 33 wieder in seine in Figur 5 links dargestellte Ausgangsstellung gerät.The left representation in FIG. 5 shows the blocking element in the unlocked state. In this state, the blocking element is inserted into the jack socket, the tube 31 coming into contact with corresponding sections of the jack socket. If the jack socket is now to be locked, the key 9 is turned, whereby the disk-shaped blocking section 33 gets into the position shown in the right-hand illustration of FIG. 5, in which it engages behind a corresponding inwardly projecting section of the jack socket. If the key is now removed, the blocking element can no longer be removed from the jack socket. The reverse process takes place to remove the blocking element, ie the key is removed rotated in the opposite direction, whereby the disk-shaped blocking section 33 returns to its starting position shown on the left in FIG.

Figur 6 zeigt eine letzte Ausführungsform der Erfindung. Auch hier ist wiederum nur das Blockierungselement ohne zugehörige Klinkenbuchse dargestellt. Auch bei dieser Ausführungsform besitzt das Blockierungselement 30 ein geeignetes Zylinderschloß mit Schloßzylinder, das in bekannter Weise über einen Schlüssel 9 betätigbar ist. Durch Drehen des Schlüssels 9 und damit des Schloßzylinders wird ein mit dem Schloßzylinder verbundenes, daran angeordnetes längliches Betätigungselement 32 gedreht, dan dessen vorderem Ende ein exzentrisch zur Achse angeordneter Vorsprung vorgesehen ist. Dieser Vorsprung ist drehbar in einer entsprechend angepaßten Ausnehmung eines Stiftes 35 angeordnet, welcher in einer entsprechenden Bohrung eines mittig am Schloß angeordneten Tubus 31, beispielsweise aus Kunststoff, geführt ist. Das längliche Element 32 erstreckt sich zentrisch ebenfalls in einem entsprechenden Hohlraum des Tubus 31. Durch Drehen des Schlüssels 9 wird das längliche Element 32 gedreht und der Stift 35 somit über den exzentrisch angeordneten Vorsprung je nach Drehrichtung auf und ab bewegt. In der offenen Stellung befindet sich der Stift vollständig innerhalb des Tubus 31, während er in der abgeschlossenen bzw. blockierten Stellung aus dem Tubus herausragt und ein Herausziehen des Blockierungselementes verhindert.Figure 6 shows a last embodiment of the invention. Again, only the blocking element is shown without an associated jack socket. In this embodiment too, the blocking element 30 has a suitable cylinder lock with a lock cylinder, which can be actuated in a known manner using a key 9. By turning the key 9 and thus the lock cylinder, an elongate actuating element 32, which is connected to the lock cylinder and is arranged thereon, is rotated, the front end of which is provided with a projection arranged eccentrically to the axis. This projection is rotatably arranged in a correspondingly adapted recess of a pin 35 which is guided in a corresponding bore in a tube 31 arranged in the center of the lock, for example made of plastic. The elongated element 32 also extends centrally in a corresponding cavity of the tube 31. By turning the key 9, the elongated element 32 is rotated and the pin 35 is thus moved up and down over the eccentrically arranged projection depending on the direction of rotation. In the open position, the pin is located completely inside the tube 31, while in the closed or blocked position it protrudes from the tube and prevents the blocking element from being pulled out.
