Description

Die vorliegende Erfindung betrifft ein Blockierungselement für 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 blocking element for a jack socket for amplifiers, loudspeakers, electrical musical instruments and the like. Like., Which has a socket part for 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 Kontakt-klemmen 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 bore 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, whereby a corresponding recess on the plug element or projecting sections on the contact clamps latches between 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, ein Blockierungselement für eine Klinkenbuchse der eingangs beschriebenen Art zu schaffen, mit dem diese gegen unbefugte Benutzung geschützt werden kann.The present invention has for its object to provide a blocking element for a jack socket of the type described above, with which this can be protected against unauthorized use.

Diese Aufgabe wird erfindungsgemäß durch ein Blockierungselement mit den Merkmalen des Patentanspruches 1 gelöst.This object is achieved according to the invention by a blocking element with the features of patent claim 1.

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 goes without saying that only authorized persons have suitable means for unlocking the blocking element.

Das Blockierungselement besitzt ein Schloßgehäuse, einen sich vom Schloßgehäuse aus erstreckenden und in den Buchsenteil einführbaren Tubus, ein drehbares längliches Betätigungselement, das in einer sich durch den Tubus erstrekkenden Bohrung geführt ist, und einen in einer radialen Ausnehmung im Tubus angeordneten Stift, der durch Drehen des länglichen Betätigungselementes zum Verriegeln und Entriegeln des Blockierungselementes aus dem Tubus heraus- und in diesen hineinbewegbar ist.The blocking element has a lock housing, a tube which extends from the lock housing and can be inserted into the socket part, a rotatable elongate actuating element which is guided in a bore which extends through the tube, and a pin which is arranged in a radial recess in the tube and which is rotated of the elongated actuating element for locking and unlocking the blocking element out of the tube and into it is movable.

Zum Stand der Technik sei noch auf die US-A-2 677 261 verwiesen. In dieser Veröffentlichung ist ein Blockierungselement für einen Türhandgriff bei einem Kühlschrank beschrieben. Dabei ist ein drehbares Betätigungselement vorgesehen, das sich durch einen von einem Schloßgehäuse ausgehenden Tubus erstreckt. Die Verriegelung erfolgt durch Drehen des Betätigungselementes, so daß ein am vorderen Ende des Betätigungselementes einstückig hiermit ausgebildeter Haken in eine Verriegelungsstellung gedreht wird.Regarding the prior art, reference is made to US-A-2 677 261. This publication describes a blocking element for a door handle in a refrigerator. A rotatable actuating element is provided which extends through a tube extending from a lock housing. The locking takes place by rotating the actuating element, so that a hook integrally formed therewith at the front end of the actuating element is rotated into a locking position.

Die DE-U-19 09 055 bezieht sich auf eine Kindersicherung in einer üblichen Steckdose. Hierbei findet keine echte Verriegelung durch Bewegen eines Teiles statt, sondern ein Sicherungseinsatz wird lediglich in die Öffnungen der Steckdose eingesteckt.DE-U-19 09 055 relates to a child safety device in a conventional socket. There is no real locking by moving a part, but a fuse link is simply inserted into the openings of the socket.

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.

Das 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 auBerhalb des Buchsenteiles und stößt mit einem Ende gegen das vordere Buchsenteilende, während des Tubus in das Buchsenteil eingeführt ist und sich durch dieses hindurch bis in das Gehäuse (wenn vorhanden) erstreckt.The blocking element 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 end of the socket part, while the tube is inserted into the socket part and extends through it into the housing (if present).

Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels in Verbindung mit der Zeichnung im einzelnen erläutert. Es zeigen:

Figur 1
einen Vertikalschnitt durch eine Klinkenbuchse ohne eingesetztes Blockierungselement; und
Figur 2
eine schematische Darstellung eines Blockierungselementes im entriegelten und verriegelten Zustand ohne zugehörige Klinkenbuchse.
The invention is explained below using an exemplary embodiment in conjunction with the drawing. Show it:
Figure 1
a vertical section through a jack socket without an inserted blocking element; and
Figure 2
is a schematic representation of a blocking element in the unlocked and locked state without an associated jack socket.

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 socket part has in its interior a circular bore in section, which is lined with metal. A conventional electrical plug-in element (not shown) is inserted 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 State 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 the plug element is inserted into the jack socket 1, two metallic contact terminals 5 arranged in the housing 3, which run obliquely inwards, are bent radially outward 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 pulling out the plug element, 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.

Figur 2 zeigt eine Ausführungsform eines Blockierungselementes ohne zugehörige Klinkenbuchse. Das Blockierungselement 30 besitzt 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, an 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.FIG. 2 shows an embodiment of a blocking element without an associated jack socket. 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, at the front end of which an eccentrically arranged projection is provided. This projection is rotatably arranged in a correspondingly adapted recess of a pin 35 which is guided in a corresponding bore of 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.
