Definitions
- the present disclosure relates to a clasp device for securing an item of jewelry, jewelry, leather goods, or a watch, and comprising a rod, in which the rod is intended to cooperate in a locked manner with the clasp.
- the present disclosure relates to a clasp device in which the guidance of the rod and the robustness are improved.
- Pierced earrings typically have a post that is pushed through an opening formed in a person's ear, or another part of the body.
- the earring is held in place by an earring back, or clasp. Clasps are prone to falling off the post due to normal use.
- screw-back earrings unscrew due to the wearer's movement and are relatively expensive to replace when lost. They also require the post to be threaded.
- Most spring-loaded earrings also pull away from the earring post because they are not tight enough due to their design.
- Another clasp design described in WO9723145A1 comprises a central hole and its two mutually opposite ends have been bent to form mutually opposite curved legs. After forming the legs of the clasp, the hole is located centrally between them. The shank includes a portion of smaller cross-section against which the ends of the legs are pressed into frictional engagement.
- This clasp design has obvious disadvantages. As the material from which the clasp is made manufactured fatigues, the frictional engagement between the rod and the rounded abutment surfaces of the clasp decreases. When the force of said frictional engagement is reduced, the rod is likely to slip out of the clasp.
- the clasp comprises a buckle back, a base, an opening pierced in the base for the passage of the rod, a first and second primary branch extending from the base, a first elastic branch extending from the first primary branch and having a front face and a front opening for the passage of the rod, a second elastic branch extending from the second primary branch and having an intermediate face and an intermediate opening for the passage of the rod.
- the elastic branches are preloaded, so that when the buckle back is not subjected to compressive forces, the front, intermediate and base openings are not axially aligned. On the other hand, when the rod passes through the openings, the elastic branches exert a force which secures the buckle back to the rod.
- the present disclosure relates to a clasp device for securing an item of jewelry, jewelry, leather goods, or a watch item.
- the device comprises a body comprising a channel extending along a channel axis and configured to receive a stem of the item.
- the device also comprises a locking element comprising a first arm extending substantially in the direction of the channel axis and a second arm, integral with the first arm, and extending substantially perpendicular to the channel axis in a space provided in the body, the second arm comprising an opening having a lateral dimension substantially equal to that of the channel.
- the first arm is configured to exert a restoring force on the second arm, so as to maintain it in a locked position in which the opening is non-coaxial with the channel.
- the second arm is configured to be moved into an unlocked position by applying an actuating force to the first arm in a direction substantially perpendicular to the channel axis, so as to be able to introduce the stem into the opening.
- the rod includes a groove adapted to cooperate with the opening, blocking the movement of the rod in the direction along the channel axis.
- the clasp device allows for better guidance of the rod than for known clasp devices.
- the body is generally rigid, providing greater robustness to the clasp device.
- FIGS. 1 and 2 show a sectional view of a clasp device 100 for securing a jewelry item, according to one embodiment.
- the figure 3 shows a top view of the clasp device 100.
- the clasp comprises a body 10 comprising a channel 15 extending along a channel axis 16 and configured to receive a rod 20 of the article.
- a locking element 30 comprises a first arm 32 extending substantially in the direction of the channel axis 16.
- a second arm 33 integral with the first arm 32, extends substantially perpendicular to the channel axis 16 in a spacing 14 provided in the body 10.
- the second arm 33 comprises an opening 36 having a lateral dimension (i.e. a dimension according to the section, here a diameter in the case of a circular section) substantially equal to that of the channel 15.
- the rod 20, the channel 15 and the opening 36 are shown with a circular section.
- the clasp device 100 can however be configured so that at least one of the rod 20, the channel 15 and the opening 36 has a non-circular section, for example rectangular or square. In a possible configuration, the rod 20, the channel 15 and the opening 36 have a rectangular or square section.
- the first arm 32 is elastic and configured to exert a restoring force on the second arm 33.
- the second arm 33 is held in a locked position ( figure 2 ), in which the opening 36 is non-coaxial with the channel 15 (see the figure 2 And 3 ).
- the second arm 33 is configured to be moved into an unlocked position ( figure 1 ) by applying an actuating force (indicated by "P" in the figures 2 And 3 ) on the first arm 32 in a direction substantially perpendicular to the channel axis 16, so as to be able to introduce the rod 20 into the opening 36, when the rod 20 is received in the channel 15.
- the first arm 32 does not deform (does not move) as long as the rod 20 is only in the channel 15 but does not yet cooperate with the opening 36.
- the rod 20 includes a groove 22 having a groove lateral dimension smaller than the outer lateral dimension of the remainder of the rod 20.
- the groove 22 is configured to cooperate with the opening 36, so as to allow the movement of the second arm 33 in its locked position, blocking the movement of the rod 20 in the direction along the channel axis 16.
- the figure 4 shows a detail of the rod 20 with the groove 22.
- a cavity 12 is provided between the first arm 32 and the body 10.
- the cavity 12 is arranged to allow the deformation of the first arm 32 when the actuating force is applied to the latter.
- the first arm 32 is connected to the body 10 by each of its ends 31, 34.
- the actuating force is applied to the first arm 32, the latter can move the second arm 33 in the space 14 in a direction substantially perpendicular to the channel axis 16.
- FIG. 5 shows a sectional view of the clasp device 100, according to another embodiment.
- the first arm 32 is connected to the body 10 by only one of its ends 31.
- the other end 34 being free, the application of the actuating force on the first arm 32 allows the second arm 33 to pivot in spacing 14 around the connected end 31.
- the free end 34 can then move, for example substantially along an arc of a circle with a radius corresponding substantially to the distance between the connected end 31 and the second arm 33.
- the rod 20 is shown fixed on an earlobe 50.
- the first arm 32 is resilient and configured to exert a restoring force on the second arm 33, holding it in the locked position.
- the second arm 33 in the locked position the second arm 33 is slightly tilted relative to the channel 15, moving the opening 36 into a non-coaxial position with the channel 15.
- the first arm 32 may be elastic only in a portion near the connected end 31 so that the connected end 31 forms a flexible joint. In this configuration, the elasticity of the first arm 32 may be located at the connected end 31.
- FIG. 6 shows a three-dimensional view of the body 10.
- the body 10 may be formed in one piece.
- FIGS. 7a to 7d show a sectional view of the clasp device 100 according to the embodiment of the figure 5 , during the various stages of mounting the rod 20 in the body 10.
- FIG. 7a shows the clasp device 100 when the portion of the rod 20 before the groove 22 (and therefore of external lateral dimension larger than that of the groove 22) is introduced into the channel 15 by moving the body 10 relative to the rod 20 (in the direction indicated by the arrow).
- the Figure 7a shows the moment when the end 23 of the rod 20 comes into contact with the second arm 33.
- a clearance between the channel 15 and the rod 20 makes it possible to guide the rod 20 without tightening.
- the second arm 33 is in the locked position and is slightly tilted relative to the channel 15.
- the first arm 32 does not deform (does not pivot) as long as the rod 20 is only in the channel 15 but not yet cooperating with the opening 36.
- FIG. 7b shows the clasp device 100 at the moment when the rod 20 is inserted into the opening 36, when the groove 22 is not yet at the level of the opening 36.
- the rod 20 then forces the second arm 33 to pivot into the unlocked position (the direction of pivoting is indicated by the curved arrow at the bottom).
- Figure 7b The first arm 32 is also pivoted around its end 31 connected to the body 10.
- the second arm 33 exerts a force on the rod 20.
- the force exerted by the second arm 33 on the rod 20 can be between 8 and 16 N (depending on manufacturing deviations).
- the force exerted by the second arm 33 can be determined by the elasticity/flexibility of the first arm 32.
- this friction force is between 2 and 4 N (in the direction indicated by the right arrow).
- FIG 7c shows the clasp device 100 when the opening 36 is opposite the groove 22 of the rod 20.
- the lateral dimension of the groove being smaller than the external lateral dimension of the remainder of the rod 20, the opening 36 enters the groove 22, pivoting the second arm 33 into the locked position.
- the rod is then blocked in the body 10.
- the direction of the second arm 33 pivot is indicated by the curved arrow.
- the first arm 32 is also pivoted about its end 31 connected to the body 10.
- the opening 36 exerts a force on the rod 20 between 0 and 8 N (depending on manufacturing deviations). Still according to one embodiment, the force required to remove the groove 22 from the opening 36, without it being necessary to apply an actuating force to the first arm 32, is between 9 and 19 N (depending on manufacturing deviations).
- FIG 7d shows the clasp device 100 when the second arm 33 is pivoted into the unlocked position by applying an actuating force to the first arm 32 in one direction (indicated by "P" in the figure 7d ) substantially perpendicular to the channel axis 16.
- the actuating force may be applied by clamping the end of the body 10 at the second end 34 (as indicated by the two arrows "S” in the figure 7d ).
- the application of the actuating force P on the first arm 32 causes the pivoting of the second arm 33 so as to make the opening coaxial with the channel 15.
- the first arm 32 is also pivoted about its end 31 connected to the body 10.
- the force that must be applied to the first arm 32 in order to pivot the second arm 33 into the unlocked position is between 10 N and 12 N (in the case where the force is applied according to arrows S). It is however possible to remove the rod 20 from the opening 36 (unlock the clasp device 100) by applying a force less than that mentioned above. For example, it is possible to unlock the clasp device 100, and thus to remove the rod 20 from the body 10 by applying a minimum force of 5 N. In this case, the opening 36 is not necessarily strictly aligned (coaxial) with the channel 15. In general, it is possible to determine the force allowing the rod 20 to be removed from the body without applying the actuating force to the first arm 32.
- the body may comprise a chamfer 17 on the side where the rod 20 is introduced.
- the chamfer 17 makes it possible to guide the rod 20 in the channel 15 during its introduction.
- the rod end 20 may also comprise a chamfer 27 configured to facilitate the insertion of the rod 20 into the opening 36 (see for example the Figure 7a ).
- the chamfer 27 comes to press on the opening 36, the second moves allowing the opening 36 to be aligned with the channel 15. Once the opening 36 and the channel 15 are aligned, the rod can pass through the opening 36.
- the first arm 32 comprises a stop 321 coming into abutment against the body 10, limiting the movement of the first arm 32 and its deformation.
- the stop 321 can be formed by the end 331 of the second arm 33 coming into abutment against the bottom 141 of the space 14 (see the figures 2 And 3 ).
- the stop 321 can be formed by the second end 34 of the first arm 32 coming into abutment against the body 10.
- the clasp device 100 allows better guiding of the rod 20 than for known clasp devices, since the guiding is done over a significant length of the channel 15. In this way, the groove 22 does not block before meeting the opening 36. Once introduced, the rod 20 remains well guided until the groove 22 meets the opening 36. This contrasts with known clasp devices comprising folded plates, where the rod can move angularly once introduced into the device and before locking.
- the length of the channel 15 is at least twice the lateral dimension of the rod 20.
- the body 10 of the clasp device 100 is not entirely elastic, as is often the case with known clasp devices. Indeed, only the first arm 32, or even a single portion of the first arm 32 (for example when the elasticity of the first arm 32 is located at the connected end 31). The body 10 is therefore generally more rigid, providing greater robustness to the clasp device 100.
- the clasp device 100 thus makes it possible to avoid spontaneous unlocking by limping. In other words, the clasp device 100 is not likely to be unlocked accidentally, for example by being deformed by a torsional force.
- the clasp device 100 is suitable for securing a jewelry item, such as earring posts, earring clasps, brooches, hat pins, or other jewelry items, leather goods, or watch items, for example a post for holding a watch strap on the watch.
- a jewelry item such as earring posts, earring clasps, brooches, hat pins, or other jewelry items, leather goods, or watch items, for example a post for holding a watch strap on the watch.

Description
La présente divulgation concerne un dispositif de fermoir pour fixer un article de bijouterie, de joaillerie, de maroquinerie, ou un article horloger, et comportant une tige, dans lequel la tige est destinée à coopérer de manière verrouillée avec le fermoir. En particulier, la présente divulgation concerne un dispositif de fermoir dans lequel le guidage de la tige et la robustesse sont améliorés.The present disclosure relates to a clasp device for securing an item of jewelry, jewelry, leather goods, or a watch, and comprising a rod, in which the rod is intended to cooperate in a locked manner with the clasp. In particular, the present disclosure relates to a clasp device in which the guidance of the rod and the robustness are improved.
Les boucles d'oreilles percées ont typiquement une tige qui est poussée à travers une ouverture formée dans l'oreille d'une personne, ou une autre partie du corps. La boucle d'oreille est maintenue en place par un dos de boucle d'oreille, ou fermoir. Les fermoirs ont tendance à tomber de la tige en raison d'une utilisation normale. Par exemple, les boucles d'oreilles vissées se dévissent en raison du mouvement de l'utilisateur et sont relativement coûteuses à remplacer lorsqu'elles sont perdues. Ils exigent également que la tige soit filetée. La plupart des boucles d'oreilles à ressort s'éloignent également de la tige de la boucle d'oreille car elles ne sont pas assez serrées en raison de leur conception.Pierced earrings typically have a post that is pushed through an opening formed in a person's ear, or another part of the body. The earring is held in place by an earring back, or clasp. Clasps are prone to falling off the post due to normal use. For example, screw-back earrings unscrew due to the wearer's movement and are relatively expensive to replace when lost. They also require the post to be threaded. Most spring-loaded earrings also pull away from the earring post because they are not tight enough due to their design.

Cependant, dans les conceptions de fermoir connues, l'insertion de la tige dans le dos est souvent difficile, surtout pour les doigts âgés ou arthritiques. De plus, la tenue de la tige dans le dos n'est pas toujours très robuste.However, in known clasp designs, inserting the pin into the back is often difficult, especially for older or arthritic fingers. In addition, the hold of the pin in the back is not always very robust.
La présente divulgation concerne un dispositif de fermoir pour fixer un article de bijouterie, de joaillerie, de maroquinerie, ou un article horloger. Le dispositif comprend un corps comprenant un canal s'étendant selon un axe de canal et configuré pour recevoir une tige de l'article. Le dispositif comprend également un élément de verrouillage comprenant un premier bras s'étendant sensiblement dans la direction de l'axe de canal et un second bras, solidaire du premier bras, et s'étendant sensiblement perpendiculaire à l'axe de canal dans un espacement prévu dans le corps, le second bras comportant une ouverture ayant une dimension latérale sensiblement égale à celle du canal. Le premier bras est configuré pour exercer une force de rappel sur le second bras, de manière à le maintenir dans une position verrouillée dans laquelle l'ouverture est non-coaxiale avec le canal. Le second bras est configuré pour être déplacé dans une position déverrouillée en appliquant une force d'actionnement sur le premier bras dans une direction sensiblement perpendiculaire à l'axe de canal, de sorte à pouvoir introduire la tige dans l'ouverture. La tige comprend une gorge apte à coopérer avec l'ouverture, bloquant le déplacement de la tige dans la direction selon l'axe de canal.The present disclosure relates to a clasp device for securing an item of jewelry, jewelry, leather goods, or a watch item. The device comprises a body comprising a channel extending along a channel axis and configured to receive a stem of the item. The device also comprises a locking element comprising a first arm extending substantially in the direction of the channel axis and a second arm, integral with the first arm, and extending substantially perpendicular to the channel axis in a space provided in the body, the second arm comprising an opening having a lateral dimension substantially equal to that of the channel. The first arm is configured to exert a restoring force on the second arm, so as to maintain it in a locked position in which the opening is non-coaxial with the channel. The second arm is configured to be moved into an unlocked position by applying an actuating force to the first arm in a direction substantially perpendicular to the channel axis, so as to be able to introduce the stem into the opening. The rod includes a groove adapted to cooperate with the opening, blocking the movement of the rod in the direction along the channel axis.

Lorsque l'ouverture 36 coopère sur la dimension latérale extérieure de la tige 20 (sans action d'un l'utilisateur), le second bras 33 exerce une force sur la tige 20. Selon une forme d'exécution, la force exercée par le second bras 33 sur la tige 20 peut être entre 8 et 16 N (en fonction des écarts de fabrication). La force exercée par le second bras 33 peut être déterminée par l'élasticité / flexibilité du premier bras 32.When the
Il est nécessaire de dépasser une force de frottement entre l'ouverture 36 et la tige 20, de manière à déplacer l'ouverture 36 sur la dimension latérale extérieure de la tige 20, sans qu'il soit nécessaire d'appliquer une force d'actionnement sur le premier bras 32 (de manière à le déformer). Selon une forme d'exécution, cette force de frottement est entre 2 et 4 N (dans la direction indiquée par la flèche droite).It is necessary to overcome a friction force between the

Selon une forme d'exécution, la force qu'il faut appliquer sur le premier bras 32 afin de pivoter le second bras 33 dans la position déverrouillée est entre 10 N et 12 N (dans la cas où la force est appliquée selon flèches S). Il est toutefois possible de sortir la tige 20 de l'ouverture 36 (déverrouiller le dispositif de fermoir 100) en appliquant une force inférieure à celle mentionnée ci-dessus. Par exemple, il est possible de déverrouiller dispositif de fermoir 100, et donc de sortir la tige 20 du corps 10 en appliquant une force minimale de 5 N. Dans ce cas, l'ouverture 36 n'est pas nécessairement strictement alignée (coaxiale) avec le canal 15. De manière générale, il est possible de déterminer la force permettant de retirer la tige 20 du corps sans appliquer la force d'actionnement sur le premier bras 32.According to one embodiment, the force that must be applied to the
Selon une forme d'exécution, le corps peut comprendre un chanfrein 17 du côté où est introduite la tige 20. Le chanfrein 17 permet de guider la tige 20 dans le canal 15 lors de son introduction.According to one embodiment, the body may comprise a

Le dispositif de fermoir 100 permet un meilleur guidage de la tige 20 que pour les dispositifs de fermoir connus, puisque le guidage se fait sur une longueur importante du canal 15. De la sorte, la gorge 22 ne se bloque pas avant de rencontrer l'ouverture 36. Une fois introduite, la tige 20 reste bien guidée jusqu'à ce que la gorge 22 rencontre l'ouverture 36. Cela contraste avec les dispositifs de fermoir connus comprenant des plaques pliées, où la tige peut se déplacer angulaire une fois introduite dans le dispositif et avant le verrouillage.The

En effet, seul le premier bras 32, voir une seule portion du premier bras 32 (par exemple lorsque l'élasticité du premier bras 32 est localisée au niveau de l'extrémité reliée 31). Le corps 10 est donc généralement plus rigide, offrant une plus grande robustesse au dispositif de fermoir 100. Le dispositif de fermoir 100 permet ainsi d'éviter le déverrouillage spontané par boitement. Autrement dit, le dispositif de fermoir 100 n'est pas susceptible d'être déverrouillé accidentellement, par exemple en étant déformé par une force en torsion.The
Le dispositif de fermoir 100 est adapté pour la fixation d'un article de bijouterie, tel que des tiges de boucles d'oreilles, des fermoirs de boucles d'oreilles, des broches, des épingles à chapeaux, ou autres articles de bijouterie de joaillerie, de maroquinerie, ou articles horlogers, par exemple une tige pour maintenir un bracelet de montre sur la montre.The
