Description

Objet de l'inventionObject of the invention

La présente invention se rapporte à un système antivol, en particulier un système rendant impossible le vol par arrachement ou autre, pour bague ou autre article de bijouterie/joaillerie, tout en laissant la possibilité au client d'un essayage ou une présentation sur soi.The present invention relates to an antitheft system, in particular a system making it impossible to steal or otherwise steal, for a ring or other jewelery item, while leaving the possibility to the customer of a fitting or presentation on oneself.

Arrière-plan technologique et état de la techniqueTechnological background and state of the art

En bijouterie/joaillerie, on est souvent confronté au double impératif d'exposer aux yeux de la clientèle des articles de haute ou moyenne valeur, tels que la bague, qui est l'article le plus vendu en bijouterie, le collier, la gourmette, la montre, etc., tout en maximisant les moyens de sécurité contre le vol.In jewelery, one often faces the double imperative of exposing to the eyes of the customers of high or average value articles, such as the ring, which is the best-selling article in jewelery, the necklace, the curb chain, the watch, etc., while maximizing the means of security against theft.

Il existe bien entendu de nombreuses variantes de dispositifs visant à empêcher le vol de bijoux, montres, bracelets ou autres objets de valeur exposés dans le commerce (US-A-4 442 942, GB-A-2 058 560, US-A-4 463 856, US-A-4 406 372, FR-A-2 609 242,FR-A-2 756, 468, GB-A-2 181 288, EP-A-0 868 874, etc.). En particulier, on connaît des systèmes tels que vitrines, présentoirs ou coffrets ayant une plaque transparente en verre ou en plastique, verrouillables et éventuellement munis de dispositifs d'alarme sonores et/ou lumineux. On connaît également toute une série de systèmes présentant des moyens de retenue mécanique des objets de valeur (crochets ou autres). Tous ces dispositifs permettent d'exposer les objets à la vue du client potentiel, sans qu'il soit souhaitable que celui-ci les touche.There are, of course, many variations of devices aimed at preventing the theft of jewelry, watches, bracelets or other valuables on the market (US-A-4,442,942, GB-A-2,058,560, US-A- 4,463,856, US-A-4,406,372, FR-A-2,609,242, FR-A-2,756,468, GB-A-2,181,288, EP-A-0,868,874, etc.). In particular, there are known systems such as display cases, displays or cabinets having a transparent glass or plastic plate, lockable and possibly equipped with sound and / or light alarm devices. There is also a whole series of systems presenting means mechanical restraint of valuables (hooks or other). All these devices make it possible to expose the objects in the view of the potential customer, without it being desirable for him to touch them.

Cependant, le client est intéressé non seulement à regarder les bijoux exposés tels que bagues, montres, bracelets, etc., mais encore davantage à les essayer.However, the customer is interested not only in looking at exposed jewelry such as rings, watches, bracelets, etc., but even more so in trying them.

Ainsi, on a développé toute une série de dispositifs basés généralement sur le même principe suivant.Thus, we have developed a series of devices based generally on the following principle.

On utilise un boîtier qui peut être fermé à clef et qui est muni d'une série d'ouvertures, au niveau d'un panneau supérieur dédié à la présentation. La bague ou l'anneau est attaché à un fil métallique de forte résistance, l'autre extrémité du fil étant attachée à un contrepoids ou lest. Ce dernier permet à la bague de retomber dans son emplacement sur le présentoir, par gravité, lorsqu'on a cessé de manipuler la bague. Le volume du contrepoids est généralement suffisant pour permettre une obstruction au niveau de l'ouverture correspondante dans le panneau. Dans une première forme d'exécution, on ne peut retirer les bagues qui si l'on a accès à l'intérieur du boîtier (voir par exemple US-A-4 074 637, EP-A-0 674 866, EP-A-0 615 711). Dans une autre forme d'exécution, l'obstruction du contrepoids peut être enlevée via un système verrouillable à tiroir utilisant deux plaques coulissantes (voir par exemple FR-A-2 744 348, DE-A-197 06 294).A lockable housing is provided which is provided with a series of openings at an upper panel dedicated to the presentation. The ring or ring is attached to a strong wire, the other end of the wire being attached to a counterweight or ballast. The latter allows the ring to fall back into its position on the display, by gravity, when it stopped manipulating the ring. The volume of the counterweight is generally sufficient to allow obstruction at the corresponding opening in the panel. In a first embodiment, the rings can not be removed if access to the inside of the housing (see for example US-A-4,074,637, EP-A-0 674 866, EP-A -0 615 711). In another embodiment, the obstruction of the counterweight can be removed via a lockable drawer system using two sliding plates (see for example FR-A-2 744 348, DE-A-197 06 294).

Il existe également des présentoirs à fils conçus pour que la rupture d'un fil métallique d'attache de la bague, suite à un vol, ferme, respectivement ouvre, un contact électrique résultant lui-même en la fermeture, respectivement l'ouverture, d'un circuit électrique avec déclenchement d'une alarme sonore et/ou visuelle (voir par exemple FR-A-2 627 970, FR-A-2 701 645, FR-A-2 595 227).There are also wire displays designed so that the rupture of a metal wire of attachment of the ring, after a flight, closes, respectively opens, an electric contact itself resulting in the closing, respectively the opening, of an electrical circuit with triggering an audible and / or visual alarm (see for example FR-A-2 627 970, FR-A-2 701 645, FR-A-2 595 227).

La plupart de ces systèmes procurent l'inconvénient que le fil de retenue peut être arraché ou sectionné. En particulier, un fil métallique même très résistant y est toujours accessible et peut être sectionné au moyen d'un pince adéquate.Most of these systems have the disadvantage that the retaining wire can be torn off or severed. In particular, even a very strong wire is still accessible and can be cut by means of a suitable clamp.

Les systèmes électriques présentent en outre l'inconvénient d'avertir qu'un vol a été commis sans pouvoir prévenir celui-ci.Electrical systems also have the disadvantage of warning that a theft was committed without being able to prevent it.

Buts de l'inventionGoals of the invention

La présente invention vise à fournir un dispositif de sécurité spécialement adapté pour sécuriser des articles de bijouterie/joaillerie tels que bagues, anneaux, montres, bracelets, sans présenter les inconvénients de l'état de la technique.The present invention aims to provide a security device specially adapted for securing jewelry items such as rings, rings, watches, bracelets, without the disadvantages of the state of the art.

En particulier, l'invention vise à permettre au client de passer une bague à son doigt, tout en laissant le dispositif de sécurité opérationnel.In particular, the invention aims to allow the customer to pass a ring on his finger, while leaving the safety device operational.

L'invention a pour but complémentaire de fournir un dispositif et un présentoir équipé de ce dispositif qui soient très robustes.The invention aims to provide a device and a display equipped with this device that are very robust.

L'invention vise en outre à proposer un système de sécurité préventif, c'est-à-dire qui empêche le vol et non un système de sécurité qui avertit simplement qu'un vol a été commis, sans pouvoir empêcher celui-ci et bien entendu sans donner de garantie de pouvoir récupérer le bijou volé.The invention also aims to provide a preventive security system, that is to say that prevents theft and not a security system that simply warns that a theft was committed, without being able to prevent it and well. heard without giving any guarantee of being able to recover the stolen jewel.

Principaux éléments caractéristiques de l'inventionMain characteristic elements of the invention

Un objet de la présente invention concerne un dispositif antivol pour la présentation au public de bagues de démonstration ou d'articles similaires de bijouterie/joaillerie selon les termes de la revendication 1.An object of the present invention relates to an antitheft device for the presentation to the public of demonstration rings or similar articles of jewelery according to the terms of claim 1.

Ce dispositif relève du domaine technique des dispositifs de sécurité comprenant une plaque fixe présentant des ouvertures et appartenant à la face supérieure d'un boîtier ainsi que des moyens de rétention de chaque bague à ladite plaque permettant une manipulation de la bague jusqu'à une distance maximale par rapport à la plaque. La particularité de l'invention est que lesdits moyens de rétention comprennent, pour chaque bague, une tête de réception et des moyens de solidarisation de celle-ci à la bague, prolongeant un cylindre mobile pouvant coulisser au travers de l'une des ouvertures, la course du cylindre étant limitée en position de sécurité par un arrêt situé sur la plaque.This device comes within the technical field of safety devices comprising a fixed plate having openings and belonging to the upper face of a housing as well as retention means of each ring to said plate allowing manipulation of the ring to a distance maximum relative to the plate. The particularity of the invention is that said retention means comprise, for each ring, a receiving head and means for securing it to the ring, extending a movable cylinder slidable through one of the openings, the stroke of the cylinder being limited in the safety position by a stop located on the plate.

Les revendications dépendantes illustrent des modalités d'exécution préférées de l'invention.The dependent claims illustrate preferred embodiments of the invention.

Ainsi, la présente invention résout le problème technique de réaliser un présentoir plus efficace contre le vol que ceux décrits dans l'art antérieur. Le principe est d'éviter le sectionnement du fil métallique qui retient habituellement chaque bague au coffret en empêchant qu'une certaine longueur fil soit facilement accessible et sectionnable par les mâchoires d'une pince ou par tout autre objet coupant ou contondant, sauf bien entendu dans le cas trivial de la destruction de la bague par cisaillement. Selon l'invention, la bague est solidarisée à un cylindre en métal résistant et le fil de retenue fixé à la bague vient se positionner à ras du réceptacle de celle-ci.Thus, the present invention solves the technical problem of making a display more effective against theft than those described in the prior art. The principle is to avoid the cutting of the wire which usually retains each ring to the cabinet by preventing a certain wire length is easily accessible and severable by the jaws of a clamp or by any other cutting or blunt object, except of course in the trivial case of the destruction of the ring by shearing. According to the invention, the ring is secured to a cylinder of resistant metal and the retaining wire attached to the ring is positioned flush with the receptacle thereof.

Description d'une forme d'exécution préférée de l'inventionDescription of a preferred embodiment of the invention

Selon une forme d'exécution préférée de l'invention, le système de sécurité pour bague 1 comporte un tube comprenant une tête universelle 2 qui elle-même surmonte un cylindre 3. La bague 1 est solidarisée mécaniquement à la tête 2 en position verticale sur sa tranche. Ce cylindre 3 est lui-même attaché à un présentoir 4', comprenant une plaque 4 essentiellement disposée en position horizontale. Le cylindre 3 peut dans une certaine mesure être retiré vers le haut, à partir de la plaque 4, ce qui permet à l'utilisateur d'essayer la bague, c'est-à-dire de la passer à son doigt, sans qu'elle soit désolidarisée du dispositif de sécurité. On notera que, pour rendre l'essayage accessible à tous, la bague de démonstration utilisée 1 sera la bague de la plus grande taille disponible.According to a preferred embodiment of the invention, the ring security system 1 comprises a tube comprising a universal head 2 which itself overcomes a cylinder 3. The ring 1 is mechanically secured to the head 2 in a vertical position on his slice. This cylinder 3 is itself attached to a display 4 ', comprising a plate 4 essentially disposed in a horizontal position. The cylinder 3 can to some extent be withdrawn upwards, from the plate 4, which allows the user to try the ring, that is to say to pass it on his finger, without it is separated from the safety device. Note that, to make the fitting accessible to all, the demonstration ring used 1 will be the ring of the largest size available.

Sur la surface latérale du cylindre 3 a été usinée, par exemple gravée au laser, une rainure 5 essentiellement en forme de "V" inversé, limitée par deux plans perpendiculaires à l'axe du cylindre 3 et qui va en s'évasant du haut vers le bas, c'est-à-dire vers l'extrémité opposée à celle où se trouve la bague. Le cylindre 3 peut être retiré du présentoir 4' ou replacé sur celui-ci selon un mouvement vertical, grâce à une ouverture essentiellement circulaire 7' pratiquée dans une plaque supérieure du présentoir 4'. L'ouverture circulaire 7' permet au cylindre 3 de retomber par gravité toujours au même endroit sur le présentoir 4'. La plaque 4 comprend une ouverture 7 correspondant à l'ouverture 7'. L'ouverture 7 de la plaque 4 est de forme essentiellement ovale et comporte un ergot 6 qui s'oppose à l'enlèvement du cylindre 3 de la plaque 4, lorsque celle-ci est en position de sécurité verrouillée. En effet, dans cette position, on peut soulever verticalement le cylindre 3 jusqu'à ce que l'ergot 6 arrive à butée sur le cylindre 3, au niveau d'un rebord 5' constituant l'extrémité inférieure de la rainure 5. Pour déverrouiller le système, on retire horizontalement la plaque 4, pour que l'ergot 6 ne fasse plus obstacle au rebord 5' de la rainure 5. Le cylindre 3, maintenu en contact avec l'autre côté de l'ouverture ovale 7 ne présentant pas d'ergot, peut être alors complètement retiré du présentoir 4'. Ce retrait est nécessaire chaque fois qu'on veut changer de bague de démonstration sur le tube.On the lateral surface of the cylinder 3 has been machined, for example laser engraved, a substantially inverted "V" shaped groove 5, bounded by two planes perpendicular to the axis of the cylinder 3 and flaring from the top. downward, that is to say towards the end opposite to that where the ring is. The cylinder 3 can be removed from the display 4 'or placed thereon in a vertical movement, thanks to a substantially circular opening 7' formed in an upper plate of the display 4 '. The circular opening 7 ' allows the cylinder 3 to fall by gravity still in the same place on the display 4 '. The plate 4 comprises an opening 7 corresponding to the opening 7 '. The opening 7 of the plate 4 is substantially oval in shape and comprises a lug 6 which opposes the removal of the cylinder 3 from the plate 4, when the latter is in the locked safety position. Indeed, in this position, the cylinder 3 can be lifted vertically until the lug 6 reaches an abutment on the cylinder 3, at a rim 5 'constituting the lower end of the groove 5. to unlock the system, the plate 4 is removed horizontally so that the lug 6 no longer obstructs the rim 5 'of the groove 5. The cylinder 3, kept in contact with the other side of the oval opening 7, does not present no lug, can then be completely removed from the display 4 '. This removal is necessary each time you want to change the demonstration ring on the tube.

Pour éviter les chocs, un dispositif d'amortissement adéquat du cylindre 3 pourra éventuellement être prévu dans le présentoir.To avoid shocks, a suitable damping device of the cylinder 3 may optionally be provided in the display.

Donc, en position de sécurité, lorsque l'utilisateur soulève le cylindre 3 de son présentoir, celui-ci coulisse verticalement. Vu la forme en "V" inversé de la rainure usinée, à mesure que le cylindre 3 est retiré du présentoir 4', l'utilisateur a la possibilité de lui imprimer une rotation dont l'amplitude angulaire est uniquement limitée par le contact de l'ergot 6 avec les deux "traits" du "V". Vu la forme de la rainure, l'amplitude angulaire maximale devient toujours plus grande à mesure que l'on s'écarte du présentoir. Ainsi, l'utilisateur dispose d'un degré de liberté en rotation qui facilite l'insertion de la bague à son doigt ainsi que l'essayage.So, in the safety position, when the user raises the cylinder 3 of its display, the latter slides vertically. Given the inverted "V" shape of the machined groove, as the cylinder 3 is removed from the display 4 ', the user has the possibility to print a rotation whose angular amplitude is only limited by the contact of the 6 with the two "lines" of the "V". Given the shape of the groove, the maximum angular amplitude becomes greater as one moves away from the display. Thus, the user has a degree of freedom in rotation which facilitates the insertion of the ring on his finger and the fitting.

La tête universelle 2 est usinée dans sa partie supérieure de manière à présenter un creux ou une fente avec une surface 10 essentiellement cylindrique ou éventuellement conique, qui permet à la bague d'être toujours présentée en position verticale.The universal head 2 is machined in its upper part so as to have a recess or slot with a surface 10 substantially cylindrical or possibly conical, which allows the ring to be always presented in a vertical position.

En position de sécurité, la tranche de la bague de démonstration 1 est posée sur la tête 2 et est retenue par un fil d'acier trempé 11, recourbé au niveau de la fixation de la bague, plastifié, muni d'un ressort 12 et d'un pas de vis coopérant de manière auto-serrante avec un pas de vis complémentaire solidaire du cylindre 3. Par exemple, le fil aura un diamètre de 1,5 mm et une résistance à la traction de 80-90 kg.In the safety position, the edge of the demonstration ring 1 is placed on the head 2 and is retained by a hardened steel wire 11, curved at the level of the fixing of the ring, plasticized, provided with a spring 12 and a screw thread cooperating in a self-tightening manner with a complementary screw thread integral with the cylinder 3. For example, the wire will have a diameter of 1.5 mm and a tensile strength of 80-90 kg.

Afin de protéger davantage la bague de démonstration, une petite feuille de papier ou de plastique 15 peut encore être insérée entre l'anneau de la bague et le fil de retenue plastifié.In order to further protect the demonstration ring, a small sheet of paper or plastic may be further inserted between the ring ring and the plasticized retaining wire.

Avantageusement, le principe de l'invention pourra être adapté pour la présentation au public d'une pluralité de bagues. On pourra rationaliser chaque plaque 4,4' pour qu'elle présente par exemple 3 lignes de 8 bagues ou 4 lignes de 6 bagues ou encore 5 lignes de 7 bagues, etc.Advantageously, the principle of the invention may be adapted for the presentation to the public of a plurality of rings. Each plate 4,4 'can be rationalized so that it has for example 3 lines of 8 rings or 4 lines of 6 rings or 5 lines of 7 rings, etc.

Comme déjà mentionné ci-dessus, on pourra enlever les différents tubes de présentation des bagues par un déverrouillage général consistant à désolidariser la plaque supérieure 4' de la plaque inférieure 4, grâce à un mouvement de retrait coulissant horizontal. Une fois les différents tubes retirés de la plaque, chaque bague peut être libérée en dévissant le fil de retenue, au moyen d'une mollette 14 solidaire d'une tige filetée 13 complémentaire du fil à pas de vis. Ainsi, chaque tube peut être libéré indépendamment l'un de l'autre grâce à un système de plaque à guillotine, qui est avantageusement sécurisé par serrure ou cadenas et peut être libéré par mouvement de retrait transversal.As already mentioned above, it will be possible to remove the various presentation tubes of the rings by a general unlocking consisting in separating the upper plate 4 'from the lower plate 4, thanks to a horizontal sliding withdrawal movement. Once the various tubes removed from the plate, each ring can be released by unscrewing the retaining wire, by means of a wheel 14 integral with a threaded rod 13 complementary to the thread with thread. Thus, each tube can be released independently of one another through a guillotine plate system, which is advantageously secured by lock or padlock and can be released by transverse withdrawal movement.

Encore avantageusement, l'ensemble du présentoir peut être en outre protégé par un système d'alarme conventionnel sonore et/ou lumineux, sensible aux chocs.Still advantageously, the entire display can be further protected by a conventional audible alarm system and / or light sensitive to shocks.

Avantageusement, le présentoir selon l'invention pourra comporter un pied pouvant par exemple être surmonté d'un ou de trois plateaux équipés du dispositif de sécurité selon l'invention. A l'intérieur du pied seront de préférence prévus des rangements sous clé permettant de disposer des plateaux de réserve avec différentes tailles des bagues exposées comme décrit ci-dessus et qui pourront être présentées ultérieurement au client, lors d'un accueil plus personnalisé.Advantageously, the display according to the invention may comprise a foot that may for example be surmounted by one or three trays equipped with the safety device according to the invention. Inside the foot are preferably provided keyed storage to arrange spare trays with different sizes of exposed rings as described above and can be presented later to the customer, at a more personalized reception.

L'avantage de l'invention est de pouvoir offrir au client la possibilité d'essayer la bague de manière relativement confortable, tout en maintenant une sécurité totale contre le vol, sans surveillance humaine permanente, le seul moyen de neutraliser la protection étant de détruire la bague par cisaillement.The advantage of the invention is to be able to offer the customer the opportunity to try the ring in a relatively comfortable manner, while maintaining total security against theft, without permanent human surveillance, the only way to neutralize the protection being to destroy the ring by shearing.
