Abstract

A plug-type clasp for pieces of jewerly, in particular for necklaces, composed of a housing in which a sleeve is movable under the force of a spring. The sleeve has a receiving opening into which a connecting element can be inserted through a front-end opening of the housing and locked there. Both the front-end opening of the housing and the receiving opening of the sleeve are eccentrically offset from each other, so that the connecting element can only be inserted into the housing, and locked there, only after the sleeve has been pulled back against the force of the spring. Removal of the connecting part can take place in the correspondingly reversed order. Activation of the sleeve for unlocking the plug-type clasp takes place by means of an operating button, laterally guided in a longitudinal hole of the housing, so that the actual connecting areas of the plug-type clasp for pieces of jewelry, in particular necklaces, remain free of pulling stresses during the operation of the plug-type clasp. With the exception of the spring and sleeve, no other movable parts are required.

Description

Die Erfindung betrifft einen Steckverschluß für Schmuckteile, ins­besondere Schmuckketten, mit einem Gehäuse, dessen eine Stirnwandung von innen von einer Feder beaufschlagt wird, deren anderes Ende eine im Gehäuse verschiebbare Hülse beaufschlagt, die eine zur anderen Stirnseite des Gehäuses zeigende Aufnahmeöffnung aufweist, in die über eine stirnseitige Öffnung des Gehäuses ein Anschluß­teil einführbar und dort arretierbar ist.The invention relates to a plug closure for jewelry parts, in particular jewelry chains, with a housing, one end wall of which is acted upon from the inside by a spring, the other end of which acts on a sleeve which is displaceable in the housing and which has a receiving opening pointing to the other end side of the housing, into which a front opening of the housing a connector can be inserted and locked there.

Ein solcher gattungsgemäßer Steckverschluß ist aus der EP-0121953 A1 bekannt, insbesondere den zur Figur 3 gehörigen Beschreibungs­teilen. Bei diesem vorbekannten Steckverschluß weist die im Gehäuse verschiebbar gelagerte Hülse zumindest zwei zur Einstecköffnung hin zeigende elastische Zungen oder Klammern auf, die von einer kegelmantelartigen Einschnürung des Gehäuses geführt werden, derart, daß sie über Vorsprünge in eine Umfangsnut des Anschluß­teils einrasten. Diese Rastposition wird durch die Wirkung der Feder gesichert. Beim Öffnen dieses vorbekannten Steckverschlusses muß das Gehäuse festgehalten werden, die Hülse gegen die Wirkung der Feder zurückgezogen werden und das Anschlußteil aus der Auf­nahmeöffnung der Hülse entfernt werden. Da hier die Hülse aber unmittelbar mit dem anderen Anschlußende des Steckverschlusses in Verbindung steht, kann es vorkommen, daß bei unbeabsichtigtem Zug an diesem Anschlußende der Hülse diese gegen die Wirkung der Feder im Gehäuse verschoben wird und ihre vorderen Rastzungen die umlaufende Ringnut des Anschlußteils freigeben, so daß bei gleichzeitig auftretendem Zug an beiden Seiten des Steckverschlus­ses ein unbeabsichtigtes Lösen des Verschlusses und damit unter Umständen der Verlust des Schmuckteils eintreten kann.Such a generic plug closure is known from EP-0121953 A1, in particular the description parts belonging to FIG. 3. In this known plug closure, the sleeve which is displaceably mounted in the housing has at least two elastic tongues or clamps which point towards the insertion opening and which are guided by a conical jacket-like constriction of the housing in such a way that they snap into a circumferential groove of the connecting part via projections. This locking position is ensured by the action of the spring. When opening this known plug closure, the housing must be held in place, the sleeve pulled back against the action of the spring, and the connecting part removed from the receiving opening of the sleeve. Since here the sleeve is directly connected to the other connection end of the plug closure, it can happen that in the event of an unintentional pull on this connection end of the sleeve, it is moved against the action of the spring in the housing and its front locking tongues release the circumferential annular groove of the connecting part so that an unintentional loosening of the closure and thus, under certain circumstances, loss of the decorative part can occur if a train occurs at the same time on both sides of the plug closure.

Die Herstellung der Hülse mit dem angeformten Anschlußende einer­seits und den elastischen Zungen andererseits ist relativ aufwendig.The production of the sleeve with the integrally formed connection end on the one hand and the elastic tongues on the other hand is relatively complex.

Der Ösencharakter der dargestellten Anschlußenden läßt darauf schließen, daß entsprechende Ösen oder geeignete Bauteile des anschließenden Schmuckstücks, beispielsweise der Schmuckkette eingehängt werden sollen, die auch in der Lage sind axiale Kräfte zu übertragen, wie es hier zur Öffnung des Verschlusses (Ver­schiebung der Hülse gegen das Gehäuse durch axialen Zug) erfor­derlich ist.The eyelet character of the connection ends shown suggests that appropriate eyelets or suitable components of the subsequent piece of jewelry, for example the jewelry chain, are to be hung, which are also able to transmit axial forces, as is the case here for opening the closure (displacement of the sleeve against the Housing by axial pull) is required.

Es gibt jedoch auch andere Anschluß- und Verbindungsmöglichkeiten beispielsweise einer Schmuckkette an einen solchen Verschluß, beispielsweise durch Verklemmen oder Vernieten, die zweckmäßger­weise nicht axial belastet werden sollten, da sonst die Schmuck­kette ausreißen kann; für solche Anwendungen ist der vorbekannte Steckverschluß daher nicht geeignet.However, there are also other connection and connection options, for example of a jewelry chain to such a closure, for example by jamming or riveting, which should expediently not be axially loaded, since otherwise the jewelry chain can tear; the prior art plug closure is therefore not suitable for such applications.

Aufgabe der Erfindung ist daher die Weiterbildung des vorbekannten Steckverschlusses insofern, als konstruktive Vereinfachung einer­seits und eine Handhabung des Verschlusses ohne axiale Belastung der Anschlußbereiche erreicht werden soll.The object of the invention is therefore the further development of the known plug-in closure insofar as a structural simplification on the one hand and handling of the closure without axial loading of the connection areas is to be achieved.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Mittel­achse der stirnseitigen Öffnung des Gehäuses exzentrisch zur Längsachse der Aufnahmeöffnung der Hülse liegt, und daß die Hülse in der gegen die Wirkung der Feder zurückgezogenen Position (Entnahme- und Einführposition) die Verschiebung der Längsachse des Anschlußteils zwischen den beiden anderen Längsachsen gestattet.According to the invention this object is achieved in that the central axis of the front opening of the housing is eccentric to the longitudinal axis of the receiving opening of the sleeve, and that the sleeve in the position retracted against the action of the spring (removal and insertion position) the displacement of the longitudinal axis of the connecting part between allowed the other two longitudinal axes.

Der Grundgedanke der Erfindung besteht also darin, einen seitlichen Versatz der stirnseitigen Öffnung des Gehäuses zum Einführen des Anschlußteils einerseits und der Aufnahmeöffnung der im Ge­häuse verschiebbar gelagerten Hülse zum Einstecken des Anschluß­teils andererseits vorzusehen, so daß ein "Wechsel" zwischen diesen beiden Öffnungen durch das Anschlußteil nur in der gegen die Wirkung der Feder zurückgedrängten Position der Hülse ermög­licht wird, weil in dieser zurückgeschobenen Position der nötige "Freiraum" innerhalb des Gehäuses zu dieser Querbewegung des Vorderendes des Anschlußteils zur Verfügung gestellt wird.The basic idea of the invention is therefore to provide a lateral offset of the front opening of the housing for inserting the connection part on the one hand and the receiving opening of the sleeve displaceably mounted in the housing for inserting the connection part on the other hand, so that a "change" between these two openings through the connection part is only possible in the position of the sleeve pushed back against the action of the spring, because in this pushed-back position the necessary "space" is made available within the housing for this transverse movement of the front end of the connecting part.

Diese Lösung hat den Vorteil, daß keinerlei bewegliche, insbe­sondere elastische Teile der Hülse vorhanden sein müssen.This solution has the advantage that no movable, in particular elastic, parts of the sleeve have to be present.

Weiterhin ist vorgesehen, daß die Hülse nicht einstückig mit dem anderen Anschlußende des Steckverschlusses verbunden ist (wie beim Gegenstand der EP-0121953), sondern mittels eines in einem Langloch im Gehäuse geführten Betätigungsknopf gegen die Federkraft verschiebbar ist.Furthermore, it is provided that the sleeve is not connected in one piece to the other connection end of the plug closure (as in the subject of EP-0121953), but can be displaced against the spring force by means of an actuating button which is guided in an elongated hole in the housing.

Die Krafteinwirkung zum Lösen des Verschlusses erfolgt daher über diesen Betätigungsknopf, die Krafteinwirkung zur Einführung des Anschlußteils erfolgt über das Anschlußteil unmittelbar auf die Hülse, so daß in jedem Fall axiale Zugbelastungen auf die beiden gegenüberliegenden Anschlußteile des Steckverschlusses vermieden werden, da Kraftwirkungen lediglich zwischen dem Ge­häuse und der Hülse auftreten.The force to release the lock is therefore via this button, the force to insert the connector is via the connector directly on the sleeve, so that in any case axial tensile loads on the two opposite connector parts of the plug closure are avoided, since force effects only between the housing and the sleeve occur.

Weitere Ausgestaltungen der Erfindung sind Unteransprüchen zu entnehmen, ein Ausführungsbeispiel des erfindungsgemäßen Steck­verschlusses wird nun anhand von Zeichnungen näher erläutert, es zeigen:

  • Figur 1: Einen Längsschnitt durch den Steckverschluß,
  • Figur 2: einen schematischen Längsschnitt bei der Entnahme des Anschlußteils aus dem Steckverschluß, und
  • Figur 3: einen schematischen Längsschnitt beim Einstecken des Anschlußteils in den Steckverschluß.
Further embodiments of the invention can be found in the subclaims; an embodiment of the plug closure according to the invention is now explained in more detail with reference to drawings, in which:
  • Figure 1: A longitudinal section through the plug closure,
  • Figure 2: a schematic longitudinal section when removing the connector from the plug closure, and
  • Figure 3: a schematic longitudinal section when inserting the connector into the plug closure.

Der Steckverschluß besteht im wesentlichen aus einem zylindrischen Gehäuse 10 und einer in diesem Gehäuse 10 axial verschiebbar angeordneten Hülse 20, deren eines stirnseitiges Ende einen eben­falls zylindrischen Aufnahmeraum 21 bildet, dessen Längsachse A-A′ koaxial mit dem Gehäuse 10 liegt. Das eine (in der Zeichnung oben dargestellte) Ende das Gehäuses 10 ist mit einem Schraub­deckel verschlossen, der einen Anschlußzapfen 11 zur Aufnahme, beispielsweise zum Einklemmen, des Endelementes einer Schmuck­kette vorgesehen ist.The plug closure consists essentially of a cylindrical housing 10 and an axially displaceably arranged sleeve 20 in this housing 10, one end of which forms a likewise cylindrical receiving space 21, the longitudinal axis A-A 'of which is coaxial with the housing 10. One end (shown in the drawing above) of the housing 10 is closed with a screw cover, which is provided with a connecting pin 11 for receiving, for example for clamping, the end element of a jewelry chain.

Auf dem gegenüberliegenden Ende ist das Gehäuse 10 mit einer Abdeckung 16 versehen, die eine Entnahme- bzw. Einstecköffnung 15 aufweist. Die Zentrumsachse B-B′ dieser Öffnung 15 liegt außer­halb der Achse A-A′ der Aufnahmeöffnung 21, d.h. diese beiden Achsen und ihre zugehörigen Querschnitte sind nicht deckungsgleich.On the opposite end, the housing 10 is provided with a cover 16 which has a removal or insertion opening 15. The center axis B-B 'of this opening 15 lies outside the axis A-A' of the receiving opening 21, i.e. these two axes and their associated cross sections are not congruent.

Der Innenquerschnitt der Aufnahmeöffnung 21 und auch der Innen­querschnitt der Öffnung 15 sind jedoch so bemessen, daß das vordere Ende des Anschlußteils 30 in beide eingeführt werden kann.However, the inner cross section of the receiving opening 21 and also the inner cross section of the opening 15 are dimensioned such that the front end of the connecting part 30 can be inserted into both.

Das Anschlußteil 30 ist nach hinten zu verjüngt, so daß eine Ringschulter 31 gebildet wird, die mit der Innenfläche der Ab­deckung 16 als Anschlag zusammenwirkt und in der in Figur 1 dar­gestellten Verschlußposition des Steckverschlusses die Entnahme des Anschlußteils 30 verhindert, da auch ein seitliches Ausweichen des Anschlußteils durch die enge Führung der Innenwandungen der Aufnahmeöffnung 21 verhindert wird, so daß in dieser Verriegelungs­position keine Möglichkeit für das Anschlußteil 30 besteht, das Gehäuse 10 zu verlassen.The connecting part 30 is tapered towards the rear, so that an annular shoulder 31 is formed, which cooperates with the inner surface of the cover 16 as a stop and prevents the removal of the connecting part 30 in the closed position of the plug-in closure shown in FIG. 1, since lateral evasion of the Connection part is prevented by the tight guidance of the inner walls of the receiving opening 21, so that in this locking position there is no possibility for the connection part 30 to leave the housing 10.

Eine solche Entnahme setzt daher zwingend voraus, daß die Hülse 20 gegen die Wirkung der Kraft der Feder 12 weggezogen wird, so daß die "hinderlichen" Seitenwandungen der Aufnahmeöffnung 21 entfernt werden und die seitliche Versatzbewegung des Anschluß­teils 30 somit ermöglicht wird, die erforderlich ist, um dieses durch die Öffnung 15 herausziehen zu können.Such removal therefore presupposes that the sleeve 20 is pulled away against the action of the force of the spring 12, so that the "cumbersome" side walls of the receiving opening 21st are removed and the lateral offset movement of the connecting part 30 is thus made possible, which is necessary in order to be able to pull this out through the opening 15.

Zum Zurückziehen der Hülse 20 im Gehäuse 10 weist letzteres ein Langloch 13 auf, durch das ein Betätigungsknopf 14 nach außen geführt ist.To withdraw the sleeve 20 in the housing 10, the latter has an elongated hole 13 through which an actuating button 14 is guided to the outside.

In den Figuren 2 und 3 sind die beiden wesentlichen Bedienvor­gänge des Steckverschlusses skizzenhaft dargestellt:In Figures 2 and 3, the two essential operations of the plug closure are shown in outline:

Unter der Wirkung der äußeren Schubkraft F am Betätigungsknopf 14 gibt der Aufnahmeraum 21 der Hülse 20 das Anschlußteil 30 frei und dieses kann dann unter seitlichem Versatz unter minimalem Zug B aus der Öffnung 15 herausgezogen werden.Under the effect of the external thrust force F on the actuating button 14, the receiving space 21 of the sleeve 20 releases the connecting part 30 and this can then be pulled out of the opening 15 with a minimal displacement B with lateral displacement.

Zum Schließen des Verschlusses genügt es (Figur 3), wenn auf das Anschlußteil eine Druckkraft G ausgeübt wird, die ausreicht, um die Feder 12 soweit zusammenzudrücken, bis genügend Platz im Gehäuse 10 zur Verfügung steht, daß dann das Anschlußteil 30 sich seitlich verschiebt und seine Längsachse dann mit der Längsachse A-A′ der Hülse 20 fluchtet; dies bewirkt unmittelbar, daß unter der Wirkung der Feder 12 die Hülse 20 nach vorne schnappt und das Anschlußteil 30 in seiner koaxialen Position festhält, aus der eine Entnahme aus der Öffnung 15 nicht mehr möglich ist.To close the closure, it is sufficient (FIG. 3) if a pressure force G is exerted on the connecting part, which is sufficient to compress the spring 12 until sufficient space is available in the housing 10 that the connecting part 30 then moves laterally and its longitudinal axis is then aligned with the longitudinal axis AA 'of the sleeve 20; this has the direct effect that, under the action of the spring 12, the sleeve 20 snaps forward and holds the connecting part 30 in its coaxial position, from which removal from the opening 15 is no longer possible.

Zur Erleichterung dieser seitlichen Versetzbewegungen des Anschluß­teils 30 beim Schließen und Öffnen des Steckverschlusses ist es zweckmäßig, wenn die zusammenarbeitenden Ringkanten kegelstumpf­förmig ausgebildet sind, so daß sie als Führungsflächen zur Initiierung bzw. Erleichterung dieser seitlichen Versatzbewegungen dienen können.To facilitate these lateral displacement movements of the connecting part 30 when closing and opening the plug closure, it is expedient if the cooperating ring edges are frustoconical, so that they can serve as guide surfaces for initiating or facilitating these lateral displacement movements.
