Abstract

A transferable jewelry clasp that can be worn with different chains or bands which has the shape of a ring or has a central opening and has an upper part and a lower part. These parts are connected with one another on one side by means of a hinge, and on the opposite side by means of a snap clasp. It can thus be opened and closed easily. In order to ensure that the jewelry clasp is not lost, two cams directed inwardly toward the central opening are attached to the upper part. Eyelets are attached to the ends of the chain, which are so dimensioned that their internal diameters are larger than the thickness of the jewelry clasp ring and smaller than the thickness of the ring plus the height of the cam. With such dimensioning, the chain and eyelets can only be attached to a position differing from the supporting direction on the upper clasp part, and the danger of loss is avoided, even if the jewelry clasp is opened involuntarily.

Description

Die Erfindung bezieht sich auf ein übertragbares Schmuckschloss mit daran angebrachten verschiedenen Halsketten oder Bänder, deren Endösen dem Schmuckschloss angepasst sind, wobei das Schmuckschloss zweiteilig ausgebildet ist und die beiden Teile durch ein Scharnier verbunden sind und eine runde oder anders geformte zentrale Öffnung umschliessen und mittels einer dem Scharnier gegenüberliegenden Seite durch einen Schnappverschluss miteinander verbunden sind.The invention relates to a transferable jewelry lock with attached various necklaces or ribbons, the end loops of which are adapted to the jewelry lock, the jewelry lock being formed in two parts and the two parts being connected by a hinge and enclosing a round or differently shaped central opening and by means of a the hinge opposite side are connected by a snap lock.

Eine Halskette, an der ein Schmuckstück getragen wird, ist meist mit einem Schloss zur Verbindung der Kettenenden versehen. Dieses Schloss verrutscht aber oft nach Vorne und dies wirkt unschön. Eine schöne Kette käme auch mehr zur Geltung, wenn sie auf andere Weise mit dem Schmuckstück verbunden wäre. Dies wird möglich wenn das Schmuckstück selber als Schmuckschloss ausgebildet ist. Dann kann ein gesonderter Kettenverschluss entfallen und das so ausgebildete Schmuckstück kann durch Ösen an den Kettenenden gehalten werden. Das Schmuckstück selber dient dann zugleich als Schloss für die Kette. Ein so ausgebildetes Schmuckstück kann dann mit verschiedenen Ketten oder Bändern getragen werden.A necklace on which a piece of jewelry is worn is usually provided with a lock for connecting the chain ends. However, this lock often slips forward and this looks ugly. A beautiful chain would also come into its own if it were connected to the piece of jewelry in another way. This becomes possible if the piece of jewelry itself is designed as a jewelry lock. Then a separate chain lock can be omitted and the piece of jewelry thus formed can be held by eyelets at the chain ends. The piece of jewelry itself also serves as a lock for the chain. A piece of jewelry designed in this way can then be worn with various chains or ribbons.

Sie Erfindung hat sich zur Aufgabe gestellt, ein Schmuckschloss zu schaffen, das folgende Anforderungen erfüllt:The invention has set itself the task of creating a jewelry lock that meets the following requirements:

  • 1. es soll ein Schmuckschloss bilden, das vorne sichtbar getragen werden kann;1. it should form a jewelry lock that can be worn visibly at the front;
  • 2. es soll an unterschiedlichen Ketten oder Bändern getragen werden können;2. it should be able to be worn on different chains or bands;
  • 3. der Verschluss soll sich auch bei gewaltsamem Zug an der Kette nicht öffnen;3. the lock should not open even when the chain is pulled by force;
  • 4. es soll einen leicht zu öffnenden Verschluss haben;4. it should have an easy-to-open closure;
  • 5. es soll bei ungewolltem Öffnen des Verschlusses unverlierbar mit der Kette verbunden bleiben.5. It should remain captively connected to the chain if the lock is opened unintentionally.

Aus der DE-U 7 513 404 ist ein herzförmiger Verschluss für Schmuckketten bekannt geworden, den man mit einigem guten Willen als Schmuckschloss bezeichnen kann, obwohl er in der Beschreibung nur als ornamentale Ergänzung der Schmuckkette bezeichnet wird. Dieser Verschluss kann aber die unter Punkt 5 genannte Anforderung nicht erfüllen. Bei geöffnetem Verschluß hängt die Kette aus! Auch die Anforderungen nach Punkt 3 und 4 werden nur bedingt erfüllt. Bei starkem Zug an der Kette kann sich der Verschluss öffnen. Dem wird nur dadurch entgegengewirkt, dass die Kraft zum Öffnen gross ist.From DE-U 7 513 404 a heart-shaped clasp for jewelry chains has become known, which can be called a jewelry lock with some goodwill, although in the description it is only referred to as an ornamental addition to the jewelry chain. However, this closure cannot meet the requirement mentioned under point 5. When the lock is open, the chain hangs! The requirements in points 3 and 4 are also only met to a limited extent. The lock can open if the chain is pulled hard. The only way to counteract this is that the opening force is great.

Besondere Mittel, die ein Aushängen der Kette bei geöffnetem Verschluss vehindern sollen, sind aus der DE-C 377 488 bekannt geworden. Dieser Verschluss kann daher die unter Punkt 2 genannte Forderung nicht erfüllen. Ausserdem handelt sich dabei um einen einfachen Federringverschluss, der fest mit einem Kettenende verbunden ist. Es handelt sich hier um einen einfachen Gebrauchsgegenstand, der nichts mit einem Schmuckstück gemeinsam hat.DE-C 377 488 has disclosed special means which are intended to prevent the chain from being detached when the lock is open. This closure can therefore not meet the requirement mentioned under point 2. In addition, it is a simple spring ring lock that is firmly connected to a chain end. It is a simple commodity that has nothing in common with a piece of jewelry.

Die Erfindung löst die gestellte Aufgabe mit einem übertragbaren Schmuckschloss nach dem Oberbegriff der Patentanspruchs 1, wobei das Schmuckstück die im kennzeichnen den Teil des Anspruches 1 genannten Merkmale aufweist.The invention solves this problem with a transferable jewelry lock according to the preamble of claim 1, the piece of jewelry having the features mentioned in the part of claim 1.

In the drawing, some exemplary embodiments of the subject matter of the invention are shown and its manufacture is explained:
  • It shows:
  • 1 is a ring-shaped jewelry lock in a simplified representation and an enlarged scale with attached chain,
  • 2-4 the same jewelry lock for itself in different phases of opening,
  • 5-9 some variants of jewelry locks with attached chain,

Das vereinfacht und in grösserem Massstab in Figur 1 dargestellte Schmuckschloss 1 ist ringförmig ausgebildet, umfasst einen oberen Teil 2 und einen unteren Teil 3, die durch einen Scharnierbolzen 4 schwenkbar miteinander verbunden sind. An der, dem Scharnier diametral gegenüberliegenden Seite ist ein Schnappverschluss 5 angebracht, der an Hand von Figur 2 näher erläutert wird. Die Bezeichnungen oberer- und unterer Teil beziehen sich auf die Lage, die das Schmuckschloss beim Tragen, wenn es an der Kette oder am Band hängt, einnimmt. Der obere Teil 2 ist mit zwei nach innen ragenden Nocken 6, 6' versehen, der eine ist angrenzend an die Trennstelle zwischen dem oberen und dem unteren Teil, der zweite 6' an der Scharnierseite angebracht. In Figur 1 ist ersichtlich wie die Endöse 7 einer Kette 8 auf die obere Hälfte 2 aufbringbar ist. Die Oese muss dazu erst über den Nocken 6 gebracht werden und kann dann in Richtung des Pfeiles R geschwenkt werden. Die Lage der Oese weicht dabei stark von derjenigen beim Tragen ab, ist aber bei richtiger Dimensionierung die einzig mögliche Lage zum Aufbringen der Oese auf den oberen Teil. Genau genommen muss der Innendurchmesser der Endöse D so dimensioniert sein, dass

Figure imgb0001
wobei x = Breite des Nockens und y = Breite des Schmuckschlosses in radialer Richtung ist. Die Breite x des Nockens darf nicht zu gross sein, da sonst der Innendurchmesser D so gross gemacht werden müsste, dass dies die Sicherung gegen unbeabsichtigtes Aushängen zu nichte machen würde. Die richtige Dimensionierung der Oesen sichert, dass auch im Falle, dass sich das Schmuckschloss beim Tragen unbeabsichtigt öffnet, sich nicht von der Kette lösen kann. Die obere Schmuckschlosshälfte 2 ist mit einem zweiten Nocken 6' versehen, dieser sorgt dafür, dass die Oesen 7 und 7' immer im Bereich der oberen Hälfte verbleiben. Dadurch ist jede Gefahr eines Verlustes des Schmuckschlosses beim Tragen gebannt.Nebenbei sei bemerkt, dass die Kette selber kein Schloss mehr benötigt!The jewelry lock 1, which is simplified and shown on a larger scale in FIG. 1, is ring-shaped and comprises an upper part 2 and a lower part 3, which are pivotally connected to one another by a hinge pin 4. On the side diametrically opposite the hinge, a snap closure 5 is attached, which is explained in more detail with reference to FIG. 2. The designations upper and lower part refer to the position that the jewelry lock takes when it is hanging on the chain or on the belt. The upper part 2 is provided with two inwardly projecting cams 6, 6 ', one is located adjacent to the separation point between the upper and the lower part, the second 6' on the hinge side. In Figure 1 it can be seen how the end eyelet 7 of a chain 8 can be applied to the upper half 2. For this purpose, the eyelet must first be brought over the cam 6 and can then be pivoted in the direction of the arrow R. The position of the eyelet differs greatly from that when worn, but is the only possible position for attaching the eyelet to the upper part if the dimensions are correct. Strictly speaking, the inner diameter of the end loop D must be dimensioned so that
Figure imgb0001
 where x = width of the cam and y = width of the jewelry lock in the radial direction. The width x of the cam must not be too large, since otherwise the inside diameter D would have to be made so large that this would render the safeguard against unintentional detachment null. The correct dimensioning of the eyelets ensures that even if the jewelry lock opens unintentionally when worn, it cannot detach from the chain. The upper jewelry lock half 2 is provided with a second cam 6 ', which ensures that the eyelets 7 and 7' always remain in the area of the upper half. Thereby there is no risk of losing the jewelry lock when you are wearing it. It should also be noted that the chain itself no longer needs a lock!

Die Figuren 2-4 zeigen dasselbe ringförmige Schmuckschloss in kleinerem Massstab. In diesen Figuren ist eine mögliche Ausführung des Schnappverschlusses dargestellt. Am Boden einer weiten Bohrung 51 des unteren Teiles 3 ist ein federnder Stift 52 befestigt, der eine Kerbe 53 aufweist. Das freie Ende des Stiftes mit der Kerbe greift in geschlossenem Zustand in eine weite Bohrung 21 des oberen Teiles 2 ein und schnappt hinter einen Arretierungsvorsprung. Ein solcher Vorsprung lässt sich beispielsweise durch einen kleinen in eine Querbohrung eingesetzten Bolzen 22 herstellen, wie dies in Fig. 4 dargestellt ist.Figures 2-4 show the same ring-shaped jewelry lock on a smaller scale. A possible embodiment of the snap lock is shown in these figures. At the bottom of a wide bore 51 of the lower part 3, a resilient pin 52 is attached, which has a notch 53. The free end of the pin with the notch engages in a wide bore 21 of the upper part 2 in the closed state and snaps behind a locking projection. Such a projection can be produced, for example, by a small bolt 22 inserted into a transverse bore, as shown in FIG. 4.

Die Figuren 5-9 zeigen einige mögliche Ausführungsformen von Schmuckschlössern mit angehängter Kette, etwa in natürlicher Grösse. In Figur 5 sind drei je für sich zu öffnende ringförmige Schmuckschlösser durch Doppelringe zusammengehängt. Dies ermöglicht der Trägerin ein einziges, oder mehrere solcher Schmuckschlösser an immer derselben Kette anzuhängen. Unten in Figur 5 ist ein solcher Doppelring und ein einziges Schmuckschloss für sich dargestellt. Die Pfeile S und T deuten die Naht des Scharnieres S und die Trennstelle T der beiden Hälften an Die Richtung der Pfeile stimmt mit der Richtung der Fugen überein, die in geschlossenem Zustand kaum erkennbar sind. Die beiden Nocken 6,6' sind deutlich erkennbar, aber nicht mit Bezugszeichen versehen, um die Zeichnung nicht zu überlasten.Figures 5-9 show some possible embodiments of jewelry locks with an attached chain, approximately in natural size. In FIG. 5, three ring-shaped jewelry locks which are each to be opened are connected by double rings. This enables the wearer to attach one or more of these jewelry locks to the same chain. Such a double ring and a single jewelry lock are shown for themselves at the bottom in FIG. The arrows S and T indicate the seam of the hinge S and the separation point T of the two halves. The direction of the arrows coincides with the direction of the joints, which are hardly recognizable in the closed state. The two cams 6, 6 'are clearly recognizable, but are not provided with reference numerals in order not to overload the drawing.

Figur 6 zeigt ein herzförmiges Schmuckschloss mit Kette, entsprechend der Erfindung. Auch hier sind Scharnier S und Trennstelle T durch Pfeile in Richtung und Lage angedeutet. Die Figuren 7,8 und 9 zeigen weitere Varianten. Die Figur 7 zeigt ein Schmuckschloss, das eine einzige Kette verschliesst, die Figur 9 zeigt dasselbe Schmuckschloss, jedoch als Verschluss für ein doppelreihiges Perlencollier.Figure 6 shows a heart-shaped jewelry lock with chain, according to the invention. Here, too, hinge S and separation point T are indicated by arrows in the direction and position. Figures 7, 8 and 9 show further variants. FIG. 7 shows a jewelry lock that closes a single chain, FIG. 9 shows the same jewelry lock, but as a closure for a double-row pearl necklace.

Das Perlencollier ist in zwei getrennte Ketten aufgeteilt, die je für sich mit Endösen versehen sind. Dies ermöglicht der Trägerin das Schmuckschloss mit einer einfachen oder mit einer doppelten Kette zu tragen. Figur 10 schliesslich zeigt ein modernes Band, dessen Ende mit einer Oese 10 versehen ist. Die Oese ist mit dem damit zu verbindenden Schmuckschloss entsprechend dimensioniert, sodass die Oese nur in einer von der Tragrichtung abweichenden Lage an den oberen Teil des Schmuckschlosses anhängbar ist. An Hand der Figuren 11a-c wird die Herstellung eines verdeckten Schnappverschlusses nach den Figuren 2-4 erläutert. Dazu werden zunächst die Bohrungen 51 und 21 in den Schmuckstückhälften 2 und 3 angebracht. Bei einem ringförmigen Schmuckverschluss verlaufen diese etwa tangential. Die Bohrung 51, die den Federstift aufnehmen soll, ist tiefer als die Bohrung 21 mit dem Arretierungsbolzen 22. In die tieferen Bohrung 51 wird nun ein Federstift 52 mit verdicktem unterem Ende 54 eingesetzt und in der richtigen Lage mit Stift 55 verstiftet und verlötet (Figur 11 b).The pearl necklace is divided into two separate chains, each with its own eyelets. This enables the wearer to wear the jewelry lock with a single or a double chain. Figure 10 finally shows a modern band, the end of which is provided with an eyelet 10. The eyelet is dimensioned accordingly with the jewelry lock to be connected to it, so that the eyelet can only be attached to the upper part of the jewelry lock in a position that deviates from the carrying direction. The production of a concealed snap lock according to FIGS. 2-4 is explained with reference to FIGS. 11a-c. For this purpose, the holes 51 and 21 are first made in the jewelry halves 2 and 3. In the case of a ring-shaped jewelry clasp, these run approximately tangentially. The bore 51, which is to receive the spring pin, is deeper than the bore 21 with the locking bolt 22. A spring pin 52 with a thickened lower end 54 is now inserted into the deeper bore 51 and pinned and soldered in the correct position with pin 55 (FIG 11 b).

Jetzt wird das Schmuckschloss geschlossen, sodass das freie Ende des Federstiftes 52 in die Bohrung 21 hineinragt Jetzt kann eine quer zur Federstiftachse verlaufende Bohrung angebracht werden, an einer Stelle, die so gewählt ist, dass der Bohrer zugleich eine gerundete Kerbe 53 aus dem Federstift herausschneidet Auf diese elegante Weise ist zugleich mit dem Einsetzen eines Bolzens 22 ein Arretierungsvorsprung und die dazugehörende Arretierungskerbe geschaffenNow the jewelry lock is closed, so that the free end of the spring pin 52 protrudes into the bore 21. A bore running transversely to the spring pin axis can now be made at a location that is selected such that the drill simultaneously cuts a rounded notch 53 out of the spring pin In this elegant manner, a locking projection and the associated locking notch are created at the same time as a bolt 22 is inserted

Derartige Bohr- und Lötarbeiten sind bei einer seriemässigen- oder fabrikmässigen Herstellung unerwünscht. Die in den Figuren 12 bis 14 dargestellte Variante eines einfachen Schmuckschlosses vermeidet schwierig auszuführende Bohrarbeiten und kommt ganz ohne Löten aus.Such drilling and soldering work are undesirable in a serial or factory production. The variant of a simple jewelry lock shown in FIGS. 12 to 14 avoids drilling work that is difficult to carry out and does completely without soldering.

Der generelle Aufbau entspricht demjenigen nach Figur 1 Das Schmuckschloss besteht auch wieder aus einer oberen Hälfte 20 und einer unteren Hälfte 30, die durch einen Bolzen 40 scharnierend miteinander verbunden sind. Die Vereinfachung besteht darin, dass der Federteil 60 des Verschlusses mit Nocken 61, 61' versehen ist. Der Federteil (60) liegt in einer Nut 201 des oberen Teiles 20 und in montiertem Zustand ragen nur die beiden Nocken 61, 61' aus der Nut heraus. Der Federteil 60 ist flach, sodass er in der Nut eine Führung findet. Die beiden Enden 62 und 63 sind verbreitert, während der dazwischenliegende schmälere Teil 64 die eigentliche Feder bildet. Der verbreiterte Teil 62 ist so geformt, dass er in montiertem Zustand auf dem Grund der Nut 201 anliegt. Er ist in dieser Lage durch einen Stift 202 gehalten, wie dies Figur 12 zeigt. In montiertem Zustand liegt auch das verbreiterte Ende 63, gegebenenfalls mit geringer Verspannung, auf dem Grund der Nut 201 auf. Dieses Ende ist nicht nur mit einem Nocken 61, sondern auch noch mit einem leicht gerundeten Haken 65 versehen. In geöffnetem Zustand des Schmuckverschlusses ragt dieser Haken aus der oberen Hälfte 20 hervor.The general structure corresponds to that according to FIG. 1. The jewelry lock again consists of an upper half 20 and a lower half 30, which are hinged together by a bolt 40. The simplification is that the spring part 60 of the closure is provided with cams 61, 61 '. The spring part (60) lies in a groove 201 of the upper part 20 and in the assembled state only the two cams 61, 61 'protrude from the groove. The spring part 60 is flat so that it finds a guide in the groove. The two ends 62 and 63 are widened, while the narrow part 64 in between forms the actual spring. The widened part 62 is shaped such that it lies against the base of the groove 201 in the assembled state. It is held in this position by a pin 202, as shown in FIG. 12. In the assembled state, the widened end 63 also lies on the base of the groove 201, possibly with little tension. This end is not only provided with a cam 61, but also with a slightly rounded hook 65. When the jewelry clasp is open, this hook protrudes from the upper half 20.

Die untere Hälfte 30 des Schmuckverschlusses ist ebenfalls mit einer Nut 301 versehen, die nahe der Trennstelle eine Bohrung aufweist, in die ein Stift 302 eingesetzt ist. Werden die beiden Hälften 20, 30 geschlossen, so biegt sich der Federteil ein wenig in Richtung des Pfeiles B (Figur 14), dabei schnappt der Haken 65 hinter den Stift 302 und der Schmuckverschluss bleibt geschlossen. Die Wirkung der beiden Nocken 61, 61' ist dieselbe wie vorgehend anhand der Figur 1 beschrieben Auch dann, wenn sich der Schmuckverschluss beim Tragen unbeabsichtigt löst, bleibt er Dank den Nocken 61, 61' an den Oesen der Kette hängen. Voraussetzung dazu ist natürlich, dass diese Oesen, wie ebenfalls vorgehend beschrieben, die richtige Grösse haben.The lower half 30 of the jewelry clasp is also provided with a groove 301 which has a bore near the separation point, into which a pin 302 is inserted. If the two halves 20, 30 are closed, the spring part bends a little in the direction of arrow B (FIG. 14), the hook 65 snaps behind the pin 302 and the jewelry clasp remains closed. The effect of the two cams 61, 61 'is the same as that described above with reference to FIG. 1. Even if the jewelry clasp unintentionally loosens when worn, it remains attached to the eyes of the chain thanks to the cams 61, 61'. The prerequisite for this is, of course, that these eyelets, as also described above, are of the correct size.

Wie aus der Zeichnung ersichtlich und in der Beschreibung erwähnt, müssen auch hier bei der Montage Bohrungen angebracht und Stifte eingesetzt werden. Diese sind aber viel einfacher anzubringen wie die Bohrungen bei der Ausführung nach Figur 1. Ausserdem entfällt jegliches Löten!As can be seen from the drawing and mentioned in the description, holes must also be drilled and pins inserted during assembly. However, these are much easier to install than the holes in the embodiment according to Figure 1. In addition, no soldering is required!
