Description

Die Erfindung geht aus von einer Schließe (nachstehend in der Beschreibung auch als Collierschließe genannt) oder einem Kettenteil für Schmuckketten mit den im Oberbegriff des Anspruchs 1 enthaltenen Merkmalen.The invention is based on a clasp (hereinafter also referred to as a necklace clasp in the description) or a chain part for jewelry chains with the features contained in the preamble of claim 1.

Eine derartige Schließe ist aus DE-U-87 00 964.1 bekannt. Nachteilig bei diesen Verschlüssen ist, daß diese als Verschlüsse für Schmuckketten, insbesondere in Kordel- oder Schlauchform unbefriedigend einsetzbar sind, da sie eine Verdrillung und/oder etwaige Knickungen der Schmuckkette nicht verhindern.Such a clasp is known from DE-U-87 00 964.1. A disadvantage of these closures is that they can be used unsatisfactorily as closures for jewelry chains, in particular in the form of cords or tubes, since they do not prevent twisting and / or any kinking of the jewelry chain.

Aus der FR 26 13 193 A1 ist eine zweiteilige kastenförmig ausgebildete Schließe bekannt, welche zwischen Innenrillen des einen Teils und Aussenrillen des zweiten Teils einen eingelegten Sprengring aufweist.From FR 26 13 193 A1 a two-part box-shaped clasp is known, which has an inserted snap ring between the inner grooves of one part and the outer grooves of the second part.

Nachteilig bei der aus der FR 26 13 193 A1 bekannten Schließe ist, daß diese eine individuelle Anpassung eines Colliers jeder Ausschnittsform nicht ermöglicht.A disadvantage of the clasp known from FR 26 13 193 A1 is that it does not allow an individual adaptation of a necklace of any cutout shape.

Desweiteren ist aus der DE 37 39 743 A1 ein Bausatz aus gegeneinander bewegbaren, miteinander verbundenen Bauteilen bekannt. Dieser Bausatz besteht aus Bauteilen in Form von geometrischen Blockkörpern, wobei die Blockkörper mindestens an ihrem Umfang mehrere in sich ebene Anlageflächen für benachbarter Blockkörper aufweisen. Die Blockkörper werden durch verbindungselemente miteinander verbunden.Furthermore, a kit of mutually movable, interconnected components is known from DE 37 39 743 A1. This kit consists of components in the form of geometric block bodies, the block bodies having at least on their circumference a plurality of flat contact surfaces for adjacent block bodies. The block bodies are connected to one another by connecting elements.

Der vorliegenden Erfindung liegt das Problem zugrunde den bekannten Verschluß derart weiterzubilden, daß dieser auch als Schmuckkettenteil verwendbar ist und durch diesen eine Schmuckkette unterschiedliche geometrische Formen annehmen kann.The present invention is based on the problem of developing the known closure in such a way that it can also be used as a jewelry chain part and through this a jewelry chain can assume different geometric shapes.

Dieses Problem wird gelöst durch die Merkmale des Patentanspruchs 1. Vorteilhafte Weiterbildungen sind Gegenstand der Unteransprüche.This problem is solved by the features of claim 1. Advantageous further developments are the subject of the dependent claims.

Die erfindungsgemäße Collierschließe oder Kettenteil für Schmuckketten zeichnet sich dadurch aus, daß die Kettenanschlüsse an den Hohlkörperteilen jeweils unter Bildung einer weiteren Trennfuge angeordnet sind. Die Trennfuge des Hohlkörpers und die weiteren Trennfugen der Kettenendanschlüsse liegen in mindestens einer Stellung in drei zueinander winkligen Ebenen. Hierdurch läßt sich durch entsprechendes Verdrehen der Hohlkörperteile ein variables Collier verwirklichen, das jede Ausschnittsform bzw. jede gewünschte Trageform individuell zuläßt. Die im Winkel zueinander liegenden Anschlüsse der Kettenenden können auf vorteilhafte Weise zum Öffnen des Hohlkörpers als Griff verwendbar sein.The necklace clasp or chain part for jewelry chains according to the invention is characterized in that the chain connections on the hollow body parts are each arranged to form a further parting line. The parting line of the hollow body and the further parting lines of the chain end connections lie in at least one position in three mutually angled planes. As a result, a variable necklace can be realized by correspondingly rotating the hollow body parts, which individually allows each cutout shape or any desired wearing shape. The connections of the chain ends lying at an angle to one another can advantageously be used as a handle for opening the hollow body.

Die Collierschließe oder das Kettenteil besteht aus einem geteilten Hohlkörper, welcher vorteilhafter an seiner Trennfuge einerseits mittels Aussenrippe andererseits mittels übergreifender Innenrille verbind- und lösabr ist und weist zwischen Innenrillen des einen Teils und den Aussenrillen des zweiten Teils als Rippe wirkenden, eingelegten Sprengring. Dies hat den Vorteil, daß die Collierschließe bzw. das Kettenteil gegen selbsttätiges Öffnen gesichert ist. Je nach Verwendung des Sprengrings ist eine einstellbare Spannung möglich, welche die Teile der Collierschließe bzw.Kettenteils fest oder drehbar zueinander hält.The necklace clasp or chain part consists of a split hollow body, which is more advantageously connected and detachable at its parting line on the one hand by means of an outer rib on the other hand by means of an overlapping inner groove and has an inserted snap ring which acts as a rib between the inner grooves of one part and the outer grooves of the second part. This has the advantage that the necklace clasp or the chain part is secured against automatic opening. Depending on the use of the snap ring, an adjustable tension is possible, which holds the parts of the necklace clasp or chain part fixed or rotatable to each other.

Gemäß der Weiterbildung nach Anspruch 3 sind die Kettenenden an den Hohlkörperteilen jeweils verdrehbar mit diesen verbunden. Durch die verdrehbare Verbindung der Kettenenden mit der Schließe bzw. dem Kettenteil wird eine Verdrillen eines Colliers verhindert. Diese Verbindung der Kettenenden mit den Hohlkörperteilen hat auch den Vorteil, daß bei Schlauchketten, welche eine höhere Steifigkeit aufweisen, ein Zurückdrehen verhindert wird.According to the development according to claim 3, the chain ends are each rotatably connected to the hollow body parts. The twistable connection of the chain ends to the clasp or the chain part prevents twisting of a necklace. This connection of the chain ends to the hollow body parts also has the advantage that turning back is prevented in the case of hose chains which have a higher rigidity.

Vorteilhafter Weise sind die beiden Kettenenden über Lochungen an den Hohlkörperteilen mit Randstufung und Innenrille sowie Anschlußring mit Aussenrille als Eingriff an den Lochungen mit Trennfuge und zwischenliegendem Sprengring verbunden. Dies hat den Vorteil, daß eine einfache und sichere verdrehbare Verbindung zwischen den Kettenenden und den Hohlkörperteilen geschaffen wird. Diese Ausbildung hat auch den weiteren Vorteil, daß die Bruchgefahr an der Anschlußstelle vermindert wird, wie sie z.B. bei gelöteten Kettenendanschlüssen auftritt. Dies wird insbesondere durch den Anspruch 5 unterstützt.Advantageously, the two chain ends are connected via perforations on the hollow body parts with edge gradation and inner groove and connecting ring with outer groove as an engagement at the perforations with a joint and an intermediate snap ring. This has the advantage that a simple and secure rotatable connection between the chain ends and the hollow body parts is created. This design also has the further advantage that the risk of breakage at the connection point is reduced, as occurs, for example, in the case of soldered chain end connections. This is particularly supported by claim 5.

Gemäß der Weiterbildung nach Anspruch 6 sind an den Trennfugen prallele oder konische Zwischenringe mit entsprechend beidseitigen Sprengringanschluß auswechselbar einsetzbar und zu einer Kettenformation zusammensetzbar. Die Zwischenringe können auch in unrunder Form ausgebildet sein, wodurch eine optische Vielfalt erzeugt wird.According to the development according to claim 6, parallel or conical intermediate rings with a corresponding snap ring connection on both sides can be used interchangeably on the parting lines and assembled into a chain formation. The intermediate rings can also be designed in a non-round shape, which creates an optical variety.

Vorteilhafterweise weist bei unrunden Hohlkörpern der eine Hohlkörperteil einen zylinderförmigen Ansatz mit Aussenrille und der andere Hohlkörperteil eine Lochung mit Innenrille als Übergriff sowie einen zwischenliegenden Sprengring auf.In the case of non-circular hollow bodies, one hollow body part advantageously has a cylindrical extension with an outer groove and the other hollow body part has a perforation with an inner groove as an overlap and an intermediate snap ring.

Vorteilhafterweise sind die Hohlkörperteile an der Trennfuge mittels Nocken oder dgl. gegen Verdrehen durch Verrasten gesichert. Hierdurch wird eine stabile Kettenformation gewährleistet.Advantageously, the hollow body parts on the parting line are secured by means of cams or the like against rotation by locking. This ensures a stable chain formation.

Insbesondere bei einer Ausbildung der Collierschließe oder Kettenteils mit Nocken ist es von Vorteil, wenn der Sprengring in einem einseitig konisch auslaufenden Rillenlager liegt und durch Spreizung bei vorhandener Rastung ein Verdrehen der geteilten Hohlkörperteile zueinander ermöglicht, so daß eine neue Verraststellung einnehmbar ist.In particular, when the necklace clasp or chain part is designed with cams, it is advantageous if the snap ring is located in a groove bearing that tapers conically on one side and allows the split hollow body parts to be rotated relative to one another by spreading with the detent present, so that a new locking position can be assumed.

Handelt es sich bei der Schmuckkette um ein Schlauchgeflecht, so ist es von Vorteil, wenn die Schmuckketten im geöffneten Zustand an der Collierschliesse oder dem Kettenteil an ihren offenen Enden zugänglich sind, so dass die Kernstränge in das Schlauchgeflecht auswechselbar einbringbar sind.If the jewelry chain is a tubular braid, it is advantageous if the jewelry chains are accessible at their open ends on the necklace clasp or the chain part, so that the core strands can be interchangeably inserted into the tubular braid.

Bei Schlauchgeflechten taucht öfters das Problem der Knickstellen auf. Eine Glättung der Knickstellen kann gemäß Anspruch 11 dadurch erfolgen, daß als der Kernstränge im Schlauchgeflecht eine Seele mit beidseitigem Kugelabschluß vorgesehen ist, so dass die Endkugeln beim Durchzug durch das Schlauchgeflecht die Knickstellen glätten.The problem of kinks often appears in hose meshes. The kinks can be smoothed according to claim 11 by providing a core with a ball end on both sides as the core strands in the tubular braid, so that the end balls smooth the kinks when pulled through the tubular braid.

Von Vorteil ist es, wenn die Kugelabschlüsse mit Haken oder Ösen ausgebildet sind. Dies hat den Vorteil, daß die Seele leichter durch das Schlauchgeflecht hindurchgezogen werden kann.It is advantageous if the ball ends are designed with hooks or eyes. This has the advantage that the core can be pulled more easily through the hose network.

Aus den Figuren 1 bis 4a ist eine erste Ausführungsform einer Collierschließe ersichtlich.A first embodiment of a necklace clasp can be seen from FIGS. 1 to 4a.

Die Collierschließe besteht aus zwei geteilten Halbkugeln 1 und 2. Die Halbkugel 1 weist eine Randstufung 3 mit Aussenrille 4 auf. Die Halbkugel 2 weist eigen Übergriff 5 mit Innenrille 6 auf. Zwischenliegend ist ein Sprengring 7 angeordnet. Die Schließe weist eine Trennfuge a auf. Die beiden Halbkugeln 1 und 2 lassen sich entsprechend Figur 2 drehbar und lösbar oder bei entsprechender Passung undrehbar und wieder lösbar miteinander verbinden.The necklace clasp consists of two divided hemispheres 1 and 2. The hemisphere 1 has an edge step 3 with an outer groove 4. The hemisphere 2 has its own overlap 5 with an inner groove 6. A snap ring 7 is arranged in between. The clasp has a parting line a. The two hemispheres 1 and 2 can be rotatably and detachably connected according to FIG.

Aus der Figur 4 ist ersichtlich, daß die beiden Kettenenden 8 und 9 an den Halbkugeln 1 und 2 jeweils unter Bildung einer Trennfuge b und c angeordnet sind.It can be seen from FIG. 4 that the two chain ends 8 and 9 are each arranged on the hemispheres 1 and 2 to form a parting line b and c.

Zurückkommend auf die Figuren 1 und 2 ist aus diesen ersichtlich, daß die Halbkugel 1 eine Lochung 40 mit Randstufung 10 aufweist, in der eine Innenrille 11 ausgebildet ist. Die Halbkugel 2 weist eine Lochung 39 auf mit Randstufung 10 und Innenrille 11. Desweiteren ist jeweils ein Anschlußring 12 vorgesehen, der einen Eingriff 13 und eine Aussenrille 14 aufweist. Die Verbindung erfolgt unter Zwischenschaltung je eines Sprengrings 15, wodurch die Verbindung drehbar oder bei entsprechender Passung undrehbar- und wieder lösbar oder auch unlösbar erfolgt. Die Anschlußringe 12 für die Kettenenden 8 und 9 sind konisch ausgebildet und mit je einer Ringausnehmung 16 versehen. Die Schlauchkettenenden 8,9 weisen je eine ringförmige Aufwölbung 17 auf und lassen sich so mittels eingelegten Sprengring 18 an den jeweiligen Anschlußring 12, wie aus Fig. 2 ersichtlich, befestigen.Returning to FIGS. 1 and 2, it can be seen from these that the hemisphere 1 has a perforation 40 with edge gradation 10 in which an inner groove 11 is trained. The hemisphere 2 has a perforation 39 with edge gradation 10 and inner groove 11. Furthermore, a connecting ring 12 is provided, which has an engagement 13 and an outer groove 14. The connection is made with the interposition of a snap ring 15, so that the connection can be rotated or, with a corresponding fit, rotatable and then detachable or non-detachable. The connecting rings 12 for the chain ends 8 and 9 are conical and each have an annular recess 16. The hose chain ends 8, 9 each have an annular bulge 17 and can thus be fastened to the respective connecting ring 12 by means of an inserted snap ring 18, as can be seen in FIG. 2.

Nach Figur 3 kann in der Schmuckkette ein Kernstrang 19 auswechselbar eingezogen sein, welcher auch als Seele mit beidseitigem Kugelabschluß 20 einerseits mit Haken 21 und andererseits mit Öse 22 ausgebildet sein kann und so zum Durchzug durch die Schmuckkette bei Knickstellen bei entsprechender Dimensionierung zur Glättung Verwendung finden kann.According to Figure 3, a core strand 19 can be inserted interchangeably in the jewelry chain, which can also be designed as a soul with a ball end 20 on both sides with hook 21 on the one hand and on the other hand with eyelet 22 and can thus be used to pull through the jewelry chain at kinks with appropriate dimensions for smoothing can.

Wie besonders aus Fig. 1 bis 4 ersichtlich, sind die Trennfugen a, b und c in drei zueinander winkligen Ebenen angeordnet, wobei eine Verschlußöffnung vorallem bei winkliger Anordnung entspr. Fig. 4, wie eingezeichnet, ermöglicht wird. In Fig. 4a ist sodann eine durch die Verdrehung entlang der Trennfugen a, b und c andere Konstellation gezeigt.As can be seen particularly from FIGS. 1 to 4, the parting lines a, b and c are arranged in three mutually angled planes, a closure opening being made possible in particular with an angled arrangement according to FIG. 4, as shown. 4a shows a different constellation due to the rotation along the separating joints a, b and c.

In Figur 5 und 5a ist weiter eine Ausführung mit zusätzlich zwischen den Halbkugeln 1 und 2 eingesetzten hier konischen Ringkörpern 23 dargestellt, sowie ein zwischen zwei Kugeln 1 und 2 zwischengesetzter, teilbarer Kubus 24, 25. Bei solchen unrunden Hohlkörpern, wie aus der Schnittdarstellung nach fig. 5a ersichtlich, ist der Zylinderteil 26 als Randabsatz mit Aussenrille 27 vorgesehen, welche mit Lochungen und Innenrille als Übergriff, wie vorgeschildert, zusammenwirken.FIGS. 5 and 5a also show an embodiment with conical ring bodies 23 additionally inserted between hemispheres 1 and 2, and a divisible cube 24, 25 interposed between two balls 1 and 2. In the case of such non-circular hollow bodies, as shown in the sectional view fig. 5a, the cylinder part 26 is provided as a shoulder with an outer groove 27, which cooperate with perforations and an inner groove as an overlap, as described above.

In den Figuren 6 bis 6b ist eine weitere Ausführungsform einer Collierschließe oder Kettenteils dargestellt. Bei dem Hohlkörper handelt es sich um einen zylinderförmigen Hohlkörper, der eine Trennfuge a aufweist, welche schräg zur Radialebene verläuft. In der Figur 6a ist der Hohlkörper in einer anderen Drehstellung als in der Figur 6 dargestellt. Die Hohlkörperteile 28,29 sind mittels Sprengringverbindung 30 am Zylinderteil 31 miteinander verbunden. Die Hohlkörperteile 28 und 29 weisen jeweils einen Kettenendanschluß 32 bzw. 33 auf.A further embodiment of a necklace clasp or chain part is shown in FIGS. 6 to 6b. The hollow body is a cylindrical hollow body which has a parting line a which extends obliquely to the radial plane. FIG. 6a shows the hollow body in a different rotational position than in FIG. 6. The hollow body parts 28, 29 are connected to one another by means of a snap ring connection 30 on the cylinder part 31. The hollow body parts 28 and 29 each have a chain end connection 32 and 33, respectively.

In den Figuren 7 bis 7b ist eine Collierschließe wie in den Figuren 6 bis 6b dargestellt, die einzelnen Hohlkörperteile 28;29 sind jedoch entgegen Verdrehen durch Verrasten gesichert. Hierzu weist das Hohlkörperteil 28 Mulden 35 in der Trennfuge a und das Hohlkörperteil 29 Nocken 34, welche in die Mulden 35 einrasten, auf. Ein Sprengring 36 ist in einem einseitig konisch auslaufendem Rillenlager 37 bei entsprechender Lochung 38 angeordnet. Durch Spreizung bei Verdrehung der Hohlkörperteile 28 und 29 können die Hohlkörperteile 28 und 29 über die Verrastung, welche durch die Nocken 34 und Mulden 35 gebildet wird, hinweggebracht werden, um z.B. in eine neue Verraststellung zu gelangen.FIGS. 7 to 7b show a necklace clasp as shown in FIGS. 6 to 6b, but the individual hollow body parts 28; 29 are secured against twisting by locking. For this purpose, the hollow body part 28 has troughs 35 in the parting line a and the hollow body part 29 has cams 34 which snap into the troughs 35. A snap ring 36 is arranged in a groove bearing 37 that tapers conically on one side and has a corresponding perforation 38. By expanding the torsion of the hollow body parts 28 and 29, the hollow body parts 28 and 29 can over the latching, which is formed by the cams 34 and troughs 35, are brought away, for example in order to get into a new latching position.
