Abstract
The clasp comprises a male part (1) and a female part (2), each being fastened to one of the ends of a link such as a jewellery chain. The front portion of the male part (1) consists of a hollow ball (3), whose wall has at least one slot (4, 4'), wherein is received a body (5) made of an elastically deformable material. The body tends to separate the edges of the slot (4, 4') so as to increase the diameter of the ball (3). The female part (2) includes a housing (12) for the male part (1) with an opening for inserting the spherical portion of the male part (1). The edges of the opening (13) are rigid and its dimensions are such that the ball can be forced through the opening (13) by bearing against the edges of the opening, with reduction of the ball's diameter by drawing together of the edges of the slot (4, 4'). The design of the clasp is especially simple and it can be easily opened and closed.
Description
FERMOIR CLASP
L'invention concerne un fermoir pour attacher ensemble les deux extrémités d'un lien tel qu'une chaîne de bijouterie.The invention relates to a clasp for fastening together the two ends of a link such as a jewelry chain.
On connaît de nombreux types de fermoirs pour attacher ensemble les deux extrémités d'un lien souple, tel qu'une chaîne de bijouterie, ou encore un collier ou un bracelet. Ces fermoirs, qui sont généralement de petites dimensions afin de ne pas perturber l'aspect d'ensemble du lien, comprennent des mécanismes de fermeture comportant des pièces de verrouillage qui sont également de petites dimensions. Il en résulte que la mise en prise de ces pièces pour fermer et verrouiller le fermoir ou, au contraire, la séparation de ces pièces pour l'ouverture du fermoir, nécessite souvent des manipulations assez difficiles à réaliser et requérant une certaine dextérité ainsi qu'une bonne vue.Many types of clasps are known for attaching the two ends of a flexible link together, such as a jewelry chain, or a necklace or bracelet. These clasps, which are generally small in order not to disturb the overall appearance of the link, include closing mechanisms comprising locking pieces which are also small. As a result, the engagement of these parts to close and lock the clasp or, on the contrary, the separation of these parts for the opening of the clasp, often requires manipulations which are quite difficult to perform and require a certain dexterity as well as A good view.
En outre, la fabrication de la plupart de ces fermoirs est relativement difficile, car elle implique la réalisation et l'assemblage de pièces ayant des formes complexes et des dimensions réduites.In addition, the manufacture of most of these clasps is relatively difficult, since it involves the production and assembly of parts having complex shapes and reduced dimensions.
L'invention a pour but d'éliminer les difficultés qui viennent d'être indiquées en fournissant un fermoir agencé de manière particulièrement simple et dont les manoeuvres d'ouverture et de fermeture sont très aisées et ne requièrent ni une habileté ni une acuité visuelle particulièrement élevée, ces manoeuvres pouvant même être éventuellement effectuées sans difficulté dans l'obscurité.The invention aims to eliminate the difficulties which have just been indicated by providing a clasp arranged in a particularly simple manner and the opening and closing maneuvers of which are very easy and require neither skill nor visual acuity in particular. These maneuvers can even possibly be carried out without difficulty in the dark.
A cet effet, le fermoir selon l'invention présente les caractéristiques spécifiées dans la revendication.To this end, the clasp according to the invention has the characteristics specified in the claim.
Les buts et les caractéristiques de l'invention, ainsi que les résultats qu'elle permet d'obtenir apparaîtront encore plus clairement à la lumière de la description détaillée, qui va suivre, d'une forme d'exécution du fermoir selon l'invention, donnée à titre d'exemple non limitatif, en se référant au dessin annexé dans lequel:
Les Figs 1 A et 1 B sont des vues en perspective du fermoir, respectivement en position d'ouverture et de fermeture; etThe aims and characteristics of the invention, as well as the results which it makes it possible to obtain, will appear even more clearly in the light of the detailed description which follows of an embodiment of the clasp according to the invention. , given by way of nonlimiting example, with reference to the appended drawing in which: Figs 1 A and 1 B are perspective views of the clasp, respectively in the open and closed position; and
Les Figs 2 A à 2 C sont des vues schématiques partielles en coupe du fermoir montrant les positions relatives des pièces de ce fermoir ainsi que la configuration de la pièce mâle dans trois phases successives de l'opération de fermeture.Figs 2 A to 2 C are partial schematic sectional views of the clasp showing the relative positions of the parts of this clasp as well as the configuration of the male part in three successive phases of the closing operation.
Comme on le voit à la Fig. 1 A, le fermoir comprend une pièce mâle l , dont la partie antérieure forme une boule creuse 3 dont la paroi présente, sur sa face antérieure, deux fentes 4 et 4', perpendiculaires entre elles, s'étendant chacune sur un arc de l'ordre de 270° (par exemple, compris entre 210 et 300°).As seen in Fig. 1 A, the clasp comprises a male part l, the front part of which forms a hollow ball 3, the wall of which has, on its front face, two slots 4 and 4 ', perpendicular to each other, each extending over an arc of the '' order of 270 ° (for example, between 210 and 300 °).
L'espace intérieur de la boule 3 est entièrement rempli d'un corps sphérique 5, en matière déformable élastiquement (mieux visible aux Figs 2 A à 2 C), qui tend à écarter les bords des fentes 4 et A'.The interior space of the ball 3 is completely filled with a spherical body 5, made of elastically deformable material (better visible in Figs 2 A to 2 C), which tends to spread the edges of the slots 4 and A '.
La face postérieure de la boule 3, opposée à celle qui présente les fentes 4 et 4', est fixée sur une partie arrière allongée consistant en un appendice tronconique 6 qui porte un premier anneau 7, réuni à un deuxième anneau 8 sur lequel est fixé, par un maillon intermédiaire 9, le premier maillon 10 (Fig. 1 B) placé à l'une des extrémités libres d'une chaîne de bijouterie (non représentée).The rear face of the ball 3, opposite to that which has the slots 4 and 4 ', is fixed on an elongated rear part consisting of a frustoconical appendix 6 which carries a first ring 7, joined to a second ring 8 on which is fixed , by an intermediate link 9, the first link 10 (Fig. 1 B) placed at one of the free ends of a jewelry chain (not shown).
Le fermoir comprend, en outre, une pièce femelle 2, dont la partie antérieure 1 1 a également la forme d'une boule creuse dont l'intérieur constitue un logement 12 pour la partie en boule 3 de la pièce mâle 1.The clasp further comprises a female part 2, the front part 1 1 of which also has the shape of a hollow ball, the interior of which constitutes a housing 12 for the ball part 3 of the male part 1.
Le logement 12 présente un orifice circulaire 13 pour l'introduction de la boule 3, et les bords de cet orifice 13 sont rigides et indéformables. Le diamètre de l'orifice 13 est tel qu'il permet l'introduction de la boule 3 dans le logement 13, à condition d'exercer sur la pièce mâle 1 , tenue de préférence en pinçant l'appendice 6 entre le pouce et l'index, un effort suffisant pour permettre le passage en force de la boule 3 à travers l'orifice 13, grâce à une diminution du diamètre de la boule 3 jusqu'à une
valeur correspondant à celle de l'orifice 13, par rapprochement mutuel des bords respectifs des fentes 4 et 4'.The housing 12 has a circular orifice 13 for the introduction of the ball 3, and the edges of this orifice 13 are rigid and undeformable. The diameter of the orifice 13 is such that it allows the introduction of the ball 3 into the housing 13, provided that it exerts on the male part 1, preferably held by pinching the appendix 6 between the thumb and the 'index, sufficient effort to allow the passage of force of the ball 3 through the orifice 13, thanks to a reduction in the diameter of the ball 3 to a value corresponding to that of the orifice 13, by mutual approximation of the respective edges of the slots 4 and 4 '.
Dans la position de fermeture illustrée à la Fig. 1 B, la boule 3 est logée dans le logement 12 et elle reste retenue à l'intérieur de ce dernier par suite de l'augmentation de son diamètre sous l'effet de la force élastique exercée par la boule intérieure 5, jusqu'à une valeur supérieure au diamètre de l'orifice 13.In the closed position illustrated in FIG. 1 B, the ball 3 is housed in the housing 12 and it remains retained inside the latter due to the increase in its diameter under the effect of the elastic force exerted by the internal ball 5, up to a value greater than the diameter of the orifice 13.
La partie arrière, opposée à l'orifice 13, de la boule 1 1 de la pièce femelle 2 est, de manière similaire à l'appendice 6 de la pièce mâle 1 , fixée à un anneau 7', identique à l'anneau 7, et l'anneau 7' est lui-même, réuni à un anneau 8' identique à l'anneau 8 et portant un maillon intermédiaire 9' relié au premier maillon 10' de l'extrémité de la chaîne (non représentée), opposée à celle qui porte la pièce mâle du fermoir.The rear part, opposite the orifice 13, of the ball 1 1 of the female part 2 is, similarly to the appendix 6 of the male part 1, fixed to a ring 7 ', identical to the ring 7 , and the ring 7 'is itself, joined to a ring 8' identical to the ring 8 and carrying an intermediate link 9 'connected to the first link 10' of the end of the chain (not shown), opposite to the one wearing the male part of the clasp.
Comme représenté à la Fig. 2 A, lorsque l'on appuie la boule 3, constituant la partie antérieure de la pièce mâle 1 , contre l'orifice 13 du logement 12 de la pièce femelle 2, en vue de l'introduction de cette partie de la pièce mâle 1 dans ce logement, au début de la phase initiale de l'opération de fermeture, le diamètre de la boule 3 est supérieur à celui de l'orifice 13 en raison du fait que la force élastique exercée par le corps intérieur 5 provoque l'écartement mutuel des bords respectifs des fentes 4 et 4'.As shown in Fig. 2 A, when the ball 3 is pressed, constituting the front part of the male part 1, against the orifice 13 of the housing 12 of the female part 2, with a view to the introduction of this part of the male part 1 in this housing, at the start of the initial phase of the closing operation, the diameter of the ball 3 is greater than that of the orifice 13 due to the fact that the elastic force exerted by the internal body 5 causes the separation mutual of the respective edges of the slots 4 and 4 '.
Dans la position représentée à la Fig. 2 B, la boule 3 est engagée dans l'orifice 13 et passe à travers celui-ci grâce au fait que son diamètre est ramené à une valeur correspondant au diamètre de l'orifice 13, en surmontant la force élastique exercée par le corps 5.In the position shown in FIG. 2 B, the ball 3 is engaged in the orifice 13 and passes through it thanks to the fact that its diameter is reduced to a value corresponding to the diameter of the orifice 13, overcoming the elastic force exerted by the body 5 .
Dans la position illustrée à la Fig. 2 C, qui correspond à la phase finale de la fermeture, la boule 3 a complètement passé à travers l'orifice 13 et elle a retrouvé, sous l'effet de la force élastique exercée par le corps 5, son diamètre initial supérieur à celui de l'orifice 13. La boule 3 est ainsi retenue à l'intérieur du logement 12, tout en ayant cependant une certaine liberté de mouvement permettant notamment un pivotement
mutuel multi-directionnel d'une certaine amplitude des pièces mâle 1 et femelle 2 du fermoir.In the position illustrated in FIG. 2 C, which corresponds to the final phase of closure, the ball 3 has completely passed through the orifice 13 and it has regained, under the effect of the elastic force exerted by the body 5, its initial diameter greater than that orifice 13. The ball 3 is thus retained inside the housing 12, while however having a certain freedom of movement allowing in particular a pivoting multi-directional mutual of a certain amplitude of the male 1 and female 2 parts of the clasp.
L'ouverture du fermoir, à partir de la position représentée aux Figs 1 B et 2 C, peut s'effectuer en faisant simplement pivoter, de préférence d'un coup sec, la pièce mâle 1 , par rapport à la pièce femelle 2, en tenant à deux doigts l'une de ces pièces dans la main droite et l'autre dans la main gauche, la boule 3 venant s'appuyer contre le bord de l'orifice 13.The opening of the clasp, from the position shown in Figs 1 B and 2 C, can be carried out by simply pivoting, preferably with a sharp blow, the male part 1, relative to the female part 2, by holding one of these pieces with two fingers in the right hand and the other in the left hand, the ball 3 coming to rest against the edge of the orifice 13.
Une force relativement élevée est ainsi engendrée, sur une partie de la ligne de contact entre la paroi extérieure de la boule 3 et le bord de l'orifice 13, par suite de l'effet de levier résultant de l'appui de la boule 3 contre le bord de l'orifice 13 sur une autre partie de cette même ligne de contact. Cette force provoque le rapprochement mutuel des bords respectifs des fentes 4 et 4' en ramenant le diamètre de la boule 3 à une valeur permettant sa sortie du logement 12.A relatively high force is thus generated, on a part of the line of contact between the outer wall of the ball 3 and the edge of the orifice 13, as a result of the leverage effect resulting from the support of the ball 3 against the edge of the orifice 13 on another part of this same contact line. This force causes the respective edges of the slots 4 and 4 ′ to approach each other by reducing the diameter of the ball 3 to a value allowing it to exit the housing 12.
Il est à noter que l'effort à exercer pour réaliser cette opération est relativement faible et ne dépasse pas, par exemple, celui qui est requis pour briser une petite brindille de bois mort.It should be noted that the effort to be exerted to carry out this operation is relatively low and does not exceed, for example, that which is required to break a small twig of dead wood.
On constate, en revanche, qu'une simple traction, même brusque et énergique, exercée sur la chaîne lorsque les pièces mâle 1 et femelle 2 sont accouplées dans la position illustrée aux Figs 1 B et 2 C, en tendant à écarter, l'une de l'autre, ces deux pièces alignées le long de leurs axes longitudinaux, ne permet nullement de les séparer.We note, on the other hand, that a simple traction, even sudden and energetic, exerted on the chain when the male parts 1 and female 2 are coupled in the position illustrated in Figs 1 B and 2 C, tending to spread, the one from the other, these two pieces aligned along their longitudinal axes, in no way allows them to be separated.
Les différentes parties du fermoir qui viennent d'être décrites sont avantageusement réalisées en métal précieux, tel que le platine, l'or ou l'argent, ou un alliage d'un tel métal correspondant, par exemple, aux matériaux constitutifs de la chaîne de bijouterie.The different parts of the clasp which have just been described are advantageously made of precious metal, such as platinum, gold or silver, or an alloy of such a metal corresponding, for example, to the constituent materials of the chain. of jewelry.
Avantageusement, la boule 3 de la pièce mâle 1 est réalisée de façon telle que, en l'absence du corps intérieur 5, les bords respectifs des fentes 4 et 4' auraient tendance à se toucher, les fentes 4 et 4' étant alors complètement fermées par suite de l'élasticité des parois de la boule 3, dans ce cas, la tendance à l'écartement des bords des fentes 4 et
4', avec ouverture de ces fentes et augmentation du diamètre de la boule 3, résulte du fait que la force élastique exercée par le corps intérieur 5 est supérieure à la force antagoniste exercée par les parois de la boule extérieure 3.Advantageously, the ball 3 of the male part 1 is produced in such a way that, in the absence of the internal body 5, the respective edges of the slots 4 and 4 'would tend to touch, the slots 4 and 4' then being completely closed due to the elasticity of the walls of the ball 3, in this case, the tendency for the edges of the slots 4 to spread apart and 4 ′, with the opening of these slots and increase in the diameter of the ball 3, results from the fact that the elastic force exerted by the internal body 5 is greater than the opposing force exerted by the walls of the external ball 3.
D'après la description qui précède, on comprend que, en vue d'obtenir un fonctionnement satisfaisant du fermoir, il est souhaitable que l'effort à exercer pour vaincre la force élastique du corps intérieur 5, afin de ramener le diamètre de la boule extérieure 3 à une valeur permettant son passage à travers l'orifice 13, dans la position illustrée à la Fig. 2 B, aussi bien lors de la fermeture que de l'ouverture du fermoir, ne soit pas excessif, tout en assurant néanmoins une force suffisante de maintien de la boule 3 à l'intérieur du logement 12 en cas de traction sur le lien lorsque le fermoir est en position de fermeture.From the above description, it is understood that, in order to obtain satisfactory operation of the clasp, it is desirable that the effort to be exerted to overcome the elastic force of the inner body 5, in order to reduce the diameter of the ball external 3 at a value allowing it to pass through the orifice 13, in the position illustrated in FIG. 2 B, both when closing and when opening the clasp, is not excessive, while nevertheless ensuring sufficient force to hold the ball 3 inside the housing 12 in the event of traction on the link when the clasp is in the closed position.
Le choix du matériau élastique utilisé pour la réalisation du corps intérieur 5 est, bien entendu, décisif en vue de l'obtention d'un bon fonctionnement du fermoir.The choice of the elastic material used for the production of the inner body 5 is, of course, decisive with a view to obtaining a good functioning of the clasp.
D'excellents résultats ont été obtenus dans le cas où le diamètre de la boule 3 a une valeur de l'ordre de 2 à 3 mm, le fermoir étant réalisé en platine, en utilisant un corps intérieur 5 en caoutchouc dur. Cependant, ce corps intérieur 5 pourrait être réalisé en tout autre matériau approprié, par exemple, en résine synthétique polymère.Excellent results have been obtained in the case where the diameter of the ball 3 has a value of the order of 2 to 3 mm, the clasp being made of platinum, using an inner body 5 of hard rubber. However, this inner body 5 could be made of any other suitable material, for example, of synthetic polymer resin.
De manière générale, le choix du matériau constitutif du corps intérieur 5 est effectué en fonction de la nature du matériau utilisé pour la réalisation de la boule 3.In general, the choice of the material constituting the inner body 5 is made according to the nature of the material used for the production of the ball 3.
Il est à noter que la présence du corps intérieur 5 permet l'obtention d'un fonctionnement répondant parfaitement aux conditions indiquées ci- dessus, alors que, en l'absence d'un tel corps, il n'est pas possible d'atteindre une valeur suffisante de la force de rétention de la boule 3 dans le logement 12 sans devoir augmenter la rigidité des parois de cette dernière boule jusqu'à un degré tel que l'effort exercé pour introduire celle-ci dans le logement 12, ou l'extraire de ce logement lors de l'ouverture du fermoir, devient excessif.
Certaines modifications pourraient, bien entendu, être apportées dans l'agencement et la forme des différentes parties du fermoir qui vient d'être décrit, tout en conservant son principe de fonctionnement ainsi que les résultats qu'il permet d'obtenir.It should be noted that the presence of the internal body 5 makes it possible to obtain an operation which perfectly meets the conditions indicated above, whereas, in the absence of such a body, it is not possible to reach a sufficient value for the retention force of the ball 3 in the housing 12 without having to increase the rigidity of the walls of the latter ball to a degree such as the force exerted to introduce it into the housing 12, or l 'extracting from this housing when opening the clasp, becomes excessive. Certain modifications could, of course, be made in the arrangement and the shape of the different parts of the clasp which has just been described, while retaining its operating principle as well as the results which it makes it possible to obtain.
Par exemple, bien que dans l'exemple donné dans la description qui précède, la boule 3 a une forme sphérique, cette boule pourrait avoir une forme différente de celle d'une sphère, par exemple légèrement aplatie, similaire à celle d'une lentille, ou encore une forme ovoïde, les formes du logement 12 et de l'orifice 13 étant alors adaptées à celle de la boule ou partie bombée 3.For example, although in the example given in the preceding description, the ball 3 has a spherical shape, this ball could have a shape different from that of a sphere, for example slightly flattened, similar to that of a lens , or an ovoid shape, the shapes of the housing 12 and the orifice 13 then being adapted to that of the ball or curved part 3.
D'autre part, il est clair que le fermoir selon l'invention est susceptible de recevoir des utilisations très variées; outre celles qui découlent immédiatement de la description faite ci-dessus, par exemple en tant que dispositif d'attache de boucles d'oreilles.
On the other hand, it is clear that the clasp according to the invention is capable of receiving very varied uses; in addition to those which immediately follow from the description given above, for example as a device for attaching earrings.
