  • the invention relates to an antitheft device of a packaged or unpackaged article, comprising a clamping control part and two clamping members vis-à-vis defining a clamping zone, at least one clamping member being capable of move towards the other member under the action of the control part actuated externally with respect to the device, so as to grip an article or a package containing this article with a first clamping pressure P1, characterized in that the device comprises a gripping portion which extends away from the clamping area and which is likely to move from a close position to a position remote from this zone under the action of a traction force external to the device, the device comprising at least one movable connecting element connected to one of the clamping and which is driven in motion during the movement away from the gripping portion, thus tending to move the clamping member which it is connected towards the other clamping member to grip the article or its packaging with a second clamping pressure P2 greater than P1.
  • the additional tightening force to move from the value P1 to the value P2 is directly proportional to the tensile force.
  • the extension or protuberance formed by the gripping portion relative to the clamping zone (clamping body) causes a malicious user to seize this part by pulling on it with one hand while holding on to the other hand the item or package to separate the device from the device.
  • the at least one connecting member and the clamping member attached thereto are engaged in a movement which further presses the member against the article or the package disposed between the two clamping members.
  • the attempt of traction exerted on the gripping portion of the antitheft device causes an increase in the pressure exerted by one of the clamping members on the article or the package containing it, thus making it more difficult to separate the article or package of said device.
  • the high clamping pressure (P2> P1) is exerted only when a user tries to separate the article from the antitheft device but not outside these times.
  • the holding in position of the antitheft device on the article or its packaging is thus improved and the protection thereof against theft is enhanced.
  • only one of the clamping members moves under the action of the clamping control part, while the other clamping member moves with said at least one connecting element.
  • the gripping portion may take a form with curvatures rather than straight or straight portions, to make a user want to grasp it.
  • said at least one connecting element is driven in a reverse movement when the traction force exerted on the gripping part ceases and the latter returns to a position close to the clamping zone, thus reducing the clamping pressure at first pressure P1.
  • said at least one connecting element comprises a first portion carrying the clamping member and a second remote portion that is actuated during the movement away from the gripping portion, said at least one connecting element being can move in the manner of a lever during its actuation, thereby raising the first portion when the second portion is requested.
  • the mechanism for increasing the clamping pressure when an attempt is made to separate the device from the article by pulling on the gripping part depends on a connection element of particularly simple shape which, by a simple movement of lever or of balance, allows to accentuate the clamping pressure on the article or its packaging or reduce this pressure to a lower value as appropriate.
  • Said at least one connecting element moves as a result of contact with a suitably shaped area of the gripping portion.
  • This area serves for example ramp on which the second portion of said at least one connecting element is supported during the movement of the gripping portion.
  • the second clamping pressure is maintained as long as the gripping portion is kept at a position away from the clamping zone.
  • the increased clamping pressure is exerted when the ill-intentioned user pulls on the gripping portion to separate the device from the article or its packaging.
  • the device comprises elastic means which, when they are urged by the movement of movement away from the gripping part, tend to oppose the tensile force exerted on it and which, when the effort ceases, bring the gripping portion to the close position of the clamping zone.
  • the aforementioned elastic means comprise, for example, a compression spring which is compressed when the gripping portion of a tensile force is exerted on the gripping portion and which brings it back into position close to the expansion clamping position. spring when the tensile force ceases.
  • elastic means can play the same role, such as one or more elastic elements, for example of curved shape, the curvature of which increases during the removal of the gripping portion and whose curvature returns to its original shape (due to the elasticity of the material constituting the element or elements) when the tensile force ceases.
  • an element may be for example a curved elastic blade or lamella.
  • the two clamping members each comprise a contact element mounted on a support (for example metal) and having a curved outer surface (convex) intended to come into contact with the article or its packaging, the element contact being made of an elastically deformable flexible material which is able to deform in contact with the article or the packaging.
  • Such a contact element acts as a pad or pad which dampens or attenuates the clamping force exerted on the article or its packaging in order to come into contact with it without damaging it.
  • This element plays a role of protection of the article.
  • the contact element is for example made of an elastomeric material such as a rubber or a rubber, thus making it possible to ensure contact with the article or the particularly soft (non-aggressive) packaging.
  • At least one of the two contact elements is mounted at the end of a support which moves in a substantially axial direction constituting the clamping axis.
  • At least one of the abovementioned contact elements is injection-molded on its support, which makes it possible to fix the element in a particularly solid and reliable manner to its support with respect to a simple bonding.
  • the support (for example metallic) of the contact element or of each contact element comprises attachment zones of the injected material.
  • the attachment zones comprise passages, orifices or openings in which the injected material in liquid form penetrates and clings to it solidifying.

Description

La présente invention concerne un dispositif antivol d'un article emballé ou non et qui est susceptible d'être volé.The present invention relates to an antitheft device of an article packaged or not and which is likely to be stolen.

Certains types de produits sensibles tels que les chaussures, sacs (de façon générale, les articles de maroquinerie), vêtements, foulards, cravates ou soies (d'une façon générale, des textiles fragiles) nécessitent une protection efficace contre le vol à l'étalage.Certain types of sensitive products such as shoes, bags (generally, leather goods), clothing, scarves, ties or bristles (generally, fragile textiles) require effective protection against theft. display.

Parmi les dispositifs antivol connus, on trouve des dispositifs du type comprenant une partie de commande de serrage et deux organes de serrage en vis-à-vis entre lesquels est disposé un article à protéger ou un emballage contenant cet article.Among known antitheft devices, there are devices of the type comprising a clamping control portion and two clamping members vis-à-vis between which is disposed an article to protect or a package containing this article.

Lorsqu'un utilisateur actionne la partie de commande de serrage, l'un au moins des organes de serrage se déplace vers l'autre organe, de manière à enserrer l'article ou l'emballage avec une pression de serrage prédéterminée.When a user actuates the clamping control portion, at least one of the clamping members moves toward the other member, so as to grip the article or package with a predetermined clamping pressure.

Si la pression de serrage exercée sur l'article ou l'emballage disposé entre les deux organes de serrage se révèle trop importante, l'article ou l'emballage peut conserver des traces de cette pression élevée. Une pression trop élevée peut même, pour des articles fragiles, détériorer ces derniers.If the clamping pressure exerted on the article or the packaging disposed between the two clamping members is too great, the article or the packaging may retain traces of this high pressure. Too high a pressure can even, for fragile articles, deteriorate these.

Au contraire, si la pression de serrage est faible, alors un utilisateur mal intentionné peut, par mouvements successifs de rotation entre l'article ou l'emballage et le dispositif, parvenir à séparer l'un de l'autre.On the contrary, if the clamping pressure is low, then a malicious user can, by successive movements of rotation between the article or the packaging and the device, succeed in separating one from the other.

L'invention a pour objet un dispositif antivol d'un article emballé ou non, comprenant une partie de commande de serrage et deux organes de serrage en vis-à-vis définissant une zone de serrage, au moins un organe de serrage étant susceptible de se déplacer vers l'autre organe sous l'action de la partie de commande actionnée de façon externe par rapport au dispositif, de manière à enserrer un article ou un emballage contenant cet article avec une première pression de serrage P1, caractérisé en ce que le dispositif comprend une partie de préhension qui s'étend en éloignement de la zone de serrage et qui est susceptible de se déplacer d'une position rapprochée vers une position éloignée de cette zone sous l'action d'un effort de traction externe au dispositif, le dispositif comprenant au moins un élément de liaison mobile relié à l'un des organes de serrage et qui est entrainé en mouvement lors du mouvement d'éloignement de la partie de préhension, tendant ainsi à déplacer l'organe de serrage auquel il est relié en direction de l'autre organe de serrage afin d'enserrer l'article ou son emballage avec une deuxième pression de serrage P2 supérieure à P1.The invention relates to an antitheft device of a packaged or unpackaged article, comprising a clamping control part and two clamping members vis-à-vis defining a clamping zone, at least one clamping member being capable of move towards the other member under the action of the control part actuated externally with respect to the device, so as to grip an article or a package containing this article with a first clamping pressure P1, characterized in that the device comprises a gripping portion which extends away from the clamping area and which is likely to move from a close position to a position remote from this zone under the action of a traction force external to the device, the device comprising at least one movable connecting element connected to one of the clamping and which is driven in motion during the movement away from the gripping portion, thus tending to move the clamping member which it is connected towards the other clamping member to grip the article or its packaging with a second clamping pressure P2 greater than P1.

L'effort additionnel de serrage permettant de passer de la valeur P1 à la valeur P2 est directement proportionnel à l'effort de traction.The additional tightening force to move from the value P1 to the value P2 is directly proportional to the tensile force.

L'extension ou l'excroissance que forme la partie de préhension par rapport à la zone de serrage (corps de serrage) incite un utilisateur mal intentionné à se saisir de cette partie en tirant dessus avec une main, tout en tenant de l'autre main l'article ou l'emballage afin de séparer ce dernier du dispositif.The extension or protuberance formed by the gripping portion relative to the clamping zone (clamping body) causes a malicious user to seize this part by pulling on it with one hand while holding on to the other hand the item or package to separate the device from the device.

Dans la mesure où un mouvement de traction est exercé sur la partie de préhension, ledit au moins un élément de liaison et l'organe de serrage qui y est lié se trouvent entrainés dans un mouvement qui presse davantage l'organe contre l'article ou l'emballage disposé entre les deux organes de serrage.To the extent that a pulling movement is exerted on the gripping portion, the at least one connecting member and the clamping member attached thereto are engaged in a movement which further presses the member against the article or the package disposed between the two clamping members.

Ainsi, la tentative de traction exercée sur la partie de préhension du dispositif antivol provoque une augmentation de la pression exercée par l'un des organes de serrage sur l'article ou l'emballage le contenant, rendant ainsi plus difficile la séparation de l'article ou de l'emballage dudit dispositif.Thus, the attempt of traction exerted on the gripping portion of the antitheft device causes an increase in the pressure exerted by one of the clamping members on the article or the package containing it, thus making it more difficult to separate the article or package of said device.

L'article ou son emballage étant préalablement enserré avec une pression de serrage P1, suite à une telle tentative de traction, il est enserré avec une pression de serrage augmentée, de valeur P2 supérieure à P1.The article or its packaging being previously gripped with a clamping pressure P1, following such a tensile attempt, it is clamped with an increased clamping pressure, P2 value greater than P1.

On notera que plus l'utilisateur tire sur la partie de préhension, plus la pression exercée par l'organe de serrage sur l'article ou l'emballage est élevée.Note that the more the user pulls on the gripping part, the greater the pressure exerted by the clamping member on the article or the package is high.

Ainsi, la pression de serrage élevée (P2 > P1) n'est exercée que lorsqu'un utilisateur tente de séparer l'article du dispositif antivol mais pas en dehors de ces moments là.Thus, the high clamping pressure (P2> P1) is exerted only when a user tries to separate the article from the antitheft device but not outside these times.

De cette façon, l'article inséré entre les organes de serrage n'est pas marqué ni dégradé suite à un effort de serrage trop élevé et qui serait permanent.In this way, the article inserted between the clamping members is not marked or degraded following a clamping force that is too high and that would be permanent.

Grâce à l'invention, le maintien en position du dispositif antivol sur l'article ou son emballage est ainsi amélioré et la protection de celui-ci contre le vol est donc renforcée.Thanks to the invention, the holding in position of the antitheft device on the article or its packaging is thus improved and the protection thereof against theft is enhanced.

Dans un exemple de réalisation, un seul des organes de serrage se déplace sous l'action de la partie de commande de serrage, tandis que l'autre organe de serrage se déplace avec ledit au moins un élément de liaison.In an exemplary embodiment, only one of the clamping members moves under the action of the clamping control part, while the other clamping member moves with said at least one connecting element.

Selon une possibilité, la partie de préhension peut revêtir une forme avec des courbures plutôt que des parties droites ou rectilignes, afin de donner envie à un utilisateur de s'en saisir.According to one possibility, the gripping portion may take a form with curvatures rather than straight or straight portions, to make a user want to grasp it.

Selon une caractéristique possible, ledit au moins un élément de liaison est entrainé dans un mouvement inverse lorsque l'effort de traction exercé sur la partie de préhension cesse et que celle-ci revient dans une position rapprochée de la zone de serrage, ramenant ainsi la pression de serrage à la première pression P1.According to a possible characteristic, said at least one connecting element is driven in a reverse movement when the traction force exerted on the gripping part ceases and the latter returns to a position close to the clamping zone, thus reducing the clamping pressure at first pressure P1.

Ainsi, lorsqu'un utilisateur mal intentionné cesse de tirer sur la partie de préhension, la pression de serrage exercée sur l'article ou l'emballage de cet article revient à une pression de serrage normale (P1) qui a été calculée pour ne pas endommager l'article.Thus, when an ill-intentioned user stops pulling on the gripping portion, the clamping pressure exerted on the article or the packaging of this article returns to a normal clamping pressure (P1) which has been calculated not to damage the item.

Selon une caractéristique possible, ledit au moins un élément de liaison comprend une première portion portant l'organe de serrage et une deuxième portion distante qui est actionnée lors du mouvement d'éloignement de la partie de préhension, ledit au moins un élément de liaison étant susceptible de se déplacer à la façon d'un levier lors de son actionnement, permettant ainsi de relever la première portion lorsque la deuxième portion est sollicitée.According to a possible characteristic, said at least one connecting element comprises a first portion carrying the clamping member and a second remote portion that is actuated during the movement away from the gripping portion, said at least one connecting element being can move in the manner of a lever during its actuation, thereby raising the first portion when the second portion is requested.

Le mécanisme permettant d'augmenter la pression de serrage lors d'une tentative de séparation du dispositif de l'article par traction sur la partie de préhension dépend d'un élément de liaison de forme particulièrement simple qui, par un simple mouvement de levier ou de balancier, permet d'accentuer la pression de serrage sur l'article ou son emballage ou de ramener cette pression à une valeur inférieure selon le cas.The mechanism for increasing the clamping pressure when an attempt is made to separate the device from the article by pulling on the gripping part depends on a connection element of particularly simple shape which, by a simple movement of lever or of balance, allows to accentuate the clamping pressure on the article or its packaging or reduce this pressure to a lower value as appropriate.

Ledit au moins un élément de liaison se déplace par suite d'un contact avec une zone de forme appropriée de la partie de préhension.Said at least one connecting element moves as a result of contact with a suitably shaped area of the gripping portion.

Cette zone sert par exemple de rampe sur laquelle la deuxième portion dudit au moins un élément de liaison s'appuie lors du déplacement de la partie de préhension.This area serves for example ramp on which the second portion of said at least one connecting element is supported during the movement of the gripping portion.

Selon une caractéristique possible, la deuxième pression de serrage est maintenue tant que la partie de préhension est maintenue en position éloignée de la zone de serrage.According to a possible characteristic, the second clamping pressure is maintained as long as the gripping portion is kept at a position away from the clamping zone.

Comme déjà exposé ci-dessus, la pression de serrage augmentée s'exerce lorsque l'utilisateur mal intentionné exerce une traction sur la partie de préhension afin de séparer le dispositif de l'article ou de son emballage.As already explained above, the increased clamping pressure is exerted when the ill-intentioned user pulls on the gripping portion to separate the device from the article or its packaging.

Selon une caractéristique possible, le dispositif comporte des moyens élastiques qui, lorsqu'ils sont sollicités par le mouvement d'éloignement de la partie de préhension, tendent à s'opposer à l'effort de traction exercé sur celle-ci et qui, lorsque l'effort cesse, ramènent la partie de préhension vers la position rapprochée de la zone de serrage.According to a possible characteristic, the device comprises elastic means which, when they are urged by the movement of movement away from the gripping part, tend to oppose the tensile force exerted on it and which, when the effort ceases, bring the gripping portion to the close position of the clamping zone.

On notera que l'effort exercé par ces moyens élastiques et qui tend à s'opposer à l'effort de traction exercé sur la partie de préhension est inférieur à ce dernier. Toutefois, lorsque cet effort de traction n'est plus exercé, alors l'effort exercé par les moyens élastiques permet de ramener la partie de préhension dans sa position rapprochée de la zone de serrage et, par là même, de ramener l'organe de serrage dans une position (position initiale) où il n'exerce sur l'article ou son emballage qu'une première pression normale (P1).Note that the force exerted by these resilient means and which tends to oppose the tensile force exerted on the gripping portion is less than the latter. However, when this tensile force is no longer exerted, then the force exerted by the resilient means makes it possible to return the gripping portion to its position close to the clamping zone and, thereby, to return the tightening in a position (initial position) where it exerts on the article or its packaging only a first normal pressure (P1).

Les moyens élastiques précités comprennent, par exemple, un ressort de compression qui est comprimé lorsque la partie de préhension d'un effort de traction est exercé sur la partie de préhension et qui ramène celle-ci en position rapprochée de la position de serrage par détente du ressort lorsque l'effort de traction cesse.The aforementioned elastic means comprise, for example, a compression spring which is compressed when the gripping portion of a tensile force is exerted on the gripping portion and which brings it back into position close to the expansion clamping position. spring when the tensile force ceases.

On notera que d'autres moyens élastiques peuvent jouer le même rôle, tel qu'un ou plusieurs éléments élastiques, par exemple, de forme courbe, dont la courbure s'accentue lors de l'éloignement de la partie de préhension et dont la courbure reviendrait à sa forme initiale (du fait de l'élasticité du matériau constituant l'élément ou les éléments) lorsque l'effort de traction cesse. Un tel élément peut être par exemple une lame ou lamelle élastique incurvée.It should be noted that other elastic means can play the same role, such as one or more elastic elements, for example of curved shape, the curvature of which increases during the removal of the gripping portion and whose curvature returns to its original shape (due to the elasticity of the material constituting the element or elements) when the tensile force ceases. Such an element may be for example a curved elastic blade or lamella.

Selon une caractéristique possible, les deux organes de serrage comprennent chacun un élément de contact monté sur un support (par exemple métallique) et ayant une surface extérieure bombée (convexe) destinée à entrer en contact avec l'article ou son emballage, l'élément de contact étant réalisé dans un matériau souple élastiquement déformable qui est apte à se déformer au contact avec l'article ou l'emballage.According to one possible characteristic, the two clamping members each comprise a contact element mounted on a support (for example metal) and having a curved outer surface (convex) intended to come into contact with the article or its packaging, the element contact being made of an elastically deformable flexible material which is able to deform in contact with the article or the packaging.

Un tel élément de contact joue le rôle d'un coussinet ou d'un patin qui amortit ou atténue l'effort de serrage exercé sur l'article ou son emballage afin d'entrer en contact avec lui sans l'abîmer.Such a contact element acts as a pad or pad which dampens or attenuates the clamping force exerted on the article or its packaging in order to come into contact with it without damaging it.

Cet élément joue en quelque sorte un rôle de protection de l'article.This element plays a role of protection of the article.

L'élément de contact est par exemple réalisé dans un matériau élastomère tel qu'une gomme ou un caoutchouc, permettant ainsi d'assurer un contact avec l'article ou l'emballage particulièrement doux (non agressif).The contact element is for example made of an elastomeric material such as a rubber or a rubber, thus making it possible to ensure contact with the article or the particularly soft (non-aggressive) packaging.

De façon générale, au moins un des deux éléments de contact est monté à l'extrémité d'un support qui se déplace suivant une direction sensiblement axiale constituant l'axe de serrage.In general, at least one of the two contact elements is mounted at the end of a support which moves in a substantially axial direction constituting the clamping axis.

Selon une caractéristique possible, au moins un des éléments de contact précités est moulé par injection sur son support, ce qui permet de fixer de manière particulièrement solide et fiable l'élément à son support par rapport à un simple collage.According to a possible characteristic, at least one of the abovementioned contact elements is injection-molded on its support, which makes it possible to fix the element in a particularly solid and reliable manner to its support with respect to a simple bonding.

Selon une caractéristique possible, le support (par exemple métallique) de l'élément de contact ou de chaque élément de contact comprend des zones d'accrochage du matériau injecté.According to a possible characteristic, the support (for example metallic) of the contact element or of each contact element comprises attachment zones of the injected material.

Ces zones permettent ainsi au matériau injecté sous forme liquide de s'y accrocher lorsqu'il se refroidit et donc lorsqu'il se solidifie.These zones thus allow the injected material in liquid form to catch on when it cools and therefore when it solidifies.

Ceci permet d'obtenir un meilleur accrochage entre l'élément de contact et le support, rendant ainsi plus difficile la séparation de l'élément et de son support.This makes it possible to obtain better adhesion between the contact element and the support, thus making it more difficult to separate the element and its support.

Selon une autre caractéristique possible, les zones d'accrochage comprennent des passages, orifices ou ouvertures dans lesquels le matériau injecté sous forme liquide pénètre et s'y accroche en se solidifiant.According to another possible characteristic, the attachment zones comprise passages, orifices or openings in which the injected material in liquid form penetrates and clings to it solidifying.

De telles zones d'accrochage sont particulièrement efficaces pour obtenir un contact plus intime entre le matériau et le support et donc un accrochage plus efficace.Such attachment zones are particularly effective for achieving a more intimate contact between the material and the support and thus a more effective attachment.

Selon une caractéristique possible, le dispositif comporte au moins un organe actif ou passif qui est apte à émettre des ondes électromagnétiques vers l'extérieur du dispositif ou à en recevoir.According to a possible characteristic, the device comprises at least one active or passive member which is able to emit electromagnetic waves towards the outside of the device or to receive them.

Ainsi, le ou les organes qui sont susceptibles de coopérer avec un système complémentaire de protection/détection contre le vol (exemple : portique antivol) et/ou d'identification radiofréquence (lecteur portatif ou portique) et de déclencher une alarme sont logés dans le dispositif.Thus, the organ or bodies that are likely to cooperate with a complementary system of protection / detection against theft (eg anti-theft gantry) and / or radio frequency identification (portable reader or gantry) and to trigger an alarm are housed in the device.

L'organe porté par le dispositif est, par exemple, un organe passif qui reçoit des ondes électromagnétiques lorsqu'il est situé à proximité du système complémentaire.The organ carried by the device is, for example, a passive member which receives electromagnetic waves when it is located near the complementary system.

Un tel organe passif est, par exemple, un circuit électrique résonnant qui entre en résonnance, de façon connue, sous l'action d'ondes excitatrices émises à la fréquence de résonnance du circuit.Such a passive member is, for example, a resonant electrical circuit which resonates, in known manner, under the action of excitatory waves emitted at the resonant frequency of the circuit.

Selon une caractéristique, ledit au moins un organe de serrage susceptible de se déplacer sous l'action de la partie de commande de serrage vers l'autre organe de serrage est mobile entre deux positions :

  • une position déverrouillée destinée, d'une part, à l'introduction de l'article ou de son emballage entre les deux organes de serrage et, d'autre part, à son retrait, dans cette position l'actionnement de la partie de commande de serrage entrainant le déplacement dudit au moins un organe de serrage, et
  • une position verrouillée destinée à accrocher le dispositif sur l'article ou son emballage et dans laquelle l'actionnement de la partie de commande n'entraine pas le déplacement dudit au moins un organe de serrage, la position verrouillée étant atteinte pour une valeur prédéterminée, lors de la conception, d'un effort d'actionnement exercé sur la partie de commande de serrage.
According to one characteristic, said at least one clamping member capable of moving under the action of the clamping control part towards the other clamping member is movable between two positions:
  • an unlocked position intended, on the one hand, for the introduction of the article or its packaging between the two clamping members and, on the other hand, for its withdrawal, in this position the actuation of the control part clamping means causing said at least one clamp member to move, and
  • a locked position for hanging the device on the article or its packaging and in which the actuation of the control part does not cause the displacement of the at least one clamping member, the locked position being reached for a predetermined value, during the design, an actuating force exerted on the clamping control portion.

Cette disposition permet une sécurisation simplifiée de l'article en s'affranchissant de l'utilisation de tout matériel pour sa mise en place.This provision allows a simplified security of the article by avoiding the use of any material for its implementation.

La position verrouillée est atteinte automatiquement pour une valeur prédéterminée d'un effort d'actionnement appliqué sur la partie de commande de serrage. Ainsi, l'utilisateur souhaitant verrouiller le dispositif sur l'article à protéger afin d'empêcher son retrait exerce un effort sur la partie de commande jusqu'à atteindre une valeur prédéterminée qui dépend du dispositif lui-même, notamment du système de transmission ou mécanisme interne reliant la partie de commande de serrage aux organes. Cette valeur prédéterminée ne dépend en effet pas de l'utilisateur.The locked position is automatically reached for a predetermined value of an actuating force applied to the clamping control portion. Thus, the user wishing to lock the device on the article to be protected in order to prevent its removal exerts a force on the control part until reaching a predetermined value which depends on the device itself, particularly the transmission system or internal mechanism connecting the clamping control portion to the members. This predetermined value does not depend on the user.

Cette valeur prédéterminée une fois atteinte conduit, par conception du système ou mécanisme interne précité, à un effort prédéterminé exercé par les organes de serrage du dispositif antivol sur l'article. Il n'est alors plus possible de transmettre un effort supplémentaire aux organes de serrage (moyens d'accrochage) car le système ou mécanisme interne ne relie plus temporairement et localement la partie de commande de serrage aux organes de serrage.This predetermined value once reached leads, by design of the aforementioned system or internal mechanism, to a predetermined force exerted by the clamping members of the antitheft device on the article. It is then no longer possible to transmit additional force to the clamping members (hooking means) because the internal system or mechanism temporarily no longer connects the clamping control portion to the clamping members.

Le système ou mécanisme interne reliant la partie de commande de serrage aux organes de serrage comprend en effet, localement dans la chaine de transmission des efforts, une portion de liaison qui est conçue (dimensionnement...) pour s'interrompre de façon automatique quand l'effort qui lui est appliqué dépasse une valeur seuil (à la façon d'un fusible mécanique).The system or internal mechanism connecting the clamping control portion to the clamping members comprises, locally in the chain of transmission of forces, a connecting portion which is designed (sizing ...) to stop automatically when the force applied to it exceeds a threshold value (in the manner of a mechanical fuse).

Si l'utilisateur continue à exercer un effort sur la partie de commande de serrage, aucun effort n'est plus transmis dans la chaine de transmission en raison de l'interruption de la portion de liaison précitée.If the user continues to exert a force on the tightening control part, no effort is no longer transmitted in the transmission chain due to the interruption of the aforementioned connecting portion.

Plus particulièrement, la valeur prédéterminée de l'effort d'actionnement à appliquer à la partie de commande de serrage est définie lors de la conception du dispositif antivol et, notamment, lors de la conception des différentes pièces constituant le système ou mécanisme interne de transmission d'effort reliant la partie de commande de serrage aux organes de serrage.More particularly, the predetermined value of the actuating force to be applied to the tightening control part is defined during the design of the antitheft device and, in particular, during the design of the various parts constituting the internal transmission system or mechanism. of force connecting the clamping control portion to the clamping members.

Le dispositif fabriqué en usine comporte ainsi en lui-même le réglage de la partie de commande de serrage à la valeur prédéterminée mentionnée ci-dessus.The factory-made device thus in itself has the adjustment of the clamping control portion to the predetermined value mentioned above.

Selon une caractéristique possible, la valeur prédéterminée est telle que l'effort exercé par les organes de serrage (moyens d'accrochage du dispositif) sur l'article ou son emballage est ajusté en fonction de l'article.According to a possible characteristic, the predetermined value is such that the force exerted by the clamping members (attachment means of the device) on the article or its packaging is adjusted according to the article.

Le dimensionnement réalisé lors de la conception du dispositif est adapté à la nature et/ou au type de l'article à protéger.The dimensioning performed during the design of the device is adapted to the nature and / or the type of the article to be protected.

Pour un même type d'article, par exemple des lunettes ou des textiles fragiles, le dimensionnement est le même quel que soit le modèle d'article.For the same type of article, for example glasses or fragile textiles, the sizing is the same regardless of the article model.

Ainsi, la valeur prédéterminée de l'effort d'actionnement à appliquer à la partie de commande de serrage et de l'effort résultant (pression de serrage) exercé sur l'article ne varie pas d'un modèle à l'autre.Thus, the predetermined value of the actuating force to be applied to the clamping control portion and the resultant force (clamping pressure) exerted on the article does not vary from model to model.

Par exemple, quel que soit le modèle de lunette et notamment l'épaisseur des branches des lunettes, la valeur prédéterminée de l'effort d'actionnement et l'effort résultant exercé sur l'article sont les mêmes.For example, regardless of the model of the telescope and in particular the thickness of the branches of the spectacles, the predetermined value of the actuating force and the resultant force exerted on the article are the same.

Un dispositif est donc applicable à un même type ou à une même nature d'articles. Toutefois, pour un article de nature différente, par exemple une bouteille, un dispositif préréglé/dimensionné différemment est à utiliser.A device is therefore applicable to the same type or to the same nature of articles. However, for a different type of article, for example a bottle, a pre-set / differently sized device is to be used.

Selon un mode possible de réalisation, la partie de commande de serrage est mobile en rotation par rapport aux organes de serrage et au moins un des organes de serrage est mobile en translation grâce à un mécanisme ou système interne de liaison qui est actionné par la mise en rotation de la partie de commande de serrage. Le ou les organes de serrage se déplacent ainsi en translation suivant une direction sensiblement axiale.According to one possible embodiment, the clamping control portion is rotatable relative to the clamping members and at least one of the clamping members is movable in translation by means of an internal mechanism or linkage system which is actuated by means of in rotation of the clamping control portion. The one or more clamping members thus move in translation in a substantially axial direction.

Dans un exemple possible du mode de réalisation précité, un seul des organes de serrage est entrainé en translation sous l'action de la partie de commande de serrage.In a possible example of the aforementioned embodiment, only one of the clamping members is driven in translation under the action of the clamping control portion.

Selon un autre aspect, l'invention concerne un dispositif antivol d'un article emballé ou non, comprenant une partie de commande de serrage et deux organes de serrage en vis-à-vis définissant une zone de serrage, au moins un organe de serrage étant susceptible de se déplacer vers l'autre organe de serrage sous l'action de la partie de commande actionnée de façon externe par rapport au dispositif de manière à enserrer un article ou un emballage contenant cet article, caractérisé en ce que les deux organes de serrage comprennent chacun un élément de contact monté sur un support et ayant, au repos, une surface extérieure bombée destinée à entrer en contact avec l'article ou l'emballage le contenant, l'élément de contact étant réalisé dans un matériau souple élastiquement déformable qui est apte à se déformer au contact avec l'article ou l'emballage.According to another aspect, the invention relates to an antitheft device of an article packaged or not, comprising a clamping control portion and two clamping members vis-à-vis defining a clamping zone, to at least one clamping member being movable towards the other clamping member under the action of the control part actuated externally with respect to the device so as to grip an article or packaging containing this article, characterized in that that the two clamping members each comprise a contact element mounted on a support and having, at rest, a convex outer surface intended to come into contact with the article or the package containing it, the contact element being made in an elastically deformable flexible material which is able to deform in contact with the article or the packaging.

Les avantages et caractéristiques mentionnés ci-dessus à l'égard de l'élément de contact monté sur chaque organe de serrage s'appliquent également à la structure du dispositif antivol précité et ne seront donc pas répétés ici.The advantages and features mentioned above with respect to the contact element mounted on each clamping member also apply to the structure of the aforementioned antitheft device and therefore will not be repeated here.

Selon des caractéristiques possibles du dispositif selon ce deuxième aspect:

  • au moins un des éléments de contact est moulé par injection sur son support ;
  • le support comprend des zones d'accrochage du matériau injecté;
  • les zones d'accrochage comprennent des orifices/ouvertures dans lesquels le matériau injecté pénètre sous forme liquide et s'y accroche en se solidifiant.
According to possible characteristics of the device according to this second aspect:
  • at least one of the contact elements is injection molded on its support;
  • the support comprises attachment zones of the injected material;
  • the attachment zones comprise orifices / openings in which the injected material penetrates in liquid form and clings to it solidifying.

Selon encore un autre aspect, l'invention concerne un dispositif antivol d'un article emballé ou non, comprenant une partie de commande de serrage et deux organes de serrage en vis-à-vis définissant une zone de serrage, au moins un organe de serrage étant susceptible de se déplacer vers l'autre organe de serrage sous l'action de la partie de commande actionnée de façon externe par rapport au dispositif de manière à enserrer un article ou un emballage contenant cet article, caractérisé en ce qu'il comprend au moins une zone imprimée protégée par un capot de protection transparent.According to yet another aspect, the invention relates to an antitheft device of an article packaged or not, comprising a clamping control part and two clamping members vis-à-vis defining a clamping zone, at least one clamping member. clamping being able to move towards the other clamping member under the action of the control portion actuated externally with respect to the device so as to grip an article or a package containing this article, characterized in that it comprises at least one printed area protected by a transparent protective cover.

Cette zone imprimée comporte des inscriptions diverses (texte, dessins, logos, hologrammes, encres 3D, ... ) qui, généralement, concernent l'article à protéger.This printed area contains various inscriptions (text, drawings, logos, holograms, 3D inks, ...) which generally concern the article to be protected.

La zone imprimée est ainsi protégée mécaniquement (usure, salissures, poussières, projections de liquides, humidité, fraude, ...) par la présence du capot qui forme une surface externe du dispositif antivol et qui, de par son caractère transparent, permet de visualiser les inscriptions imprimées.The printed area is thus mechanically protected (wear, dirt, dust, liquid splashes, humidity, fraud, ...) by the presence of the cover which forms an external surface of the antitheft device and which, because of its transparent nature, makes it possible to view the printed inscriptions.

Dans la mesure où la zone imprimée ou d'impression est protégée, notamment contre l'usure, la matière de la zone d'impression ou du support d'impression peut être choisie pour se prêter de manière particulièrement satisfaisante aux procédés d'impression qui fournissent des impressions variées, complexes, faisant appel à de nombreuses couleurs et de grande qualité.Insofar as the printed or printed area is protected, in particular against wear, the material of the printing area or of the printing medium can be chosen to lend itself particularly satisfactorily to the printing processes which provide varied, complex prints with many colors and high quality.

Il n'est donc plus nécessaire de se limiter uniquement aux techniques d'impression dont les impressions sont résistantes à l'usure, du type tampographie.It is therefore no longer necessary to be limited only to printing techniques whose impressions are resistant to wear, such as pad printing.

L'incorporation dans le dispositif antivol d'au moins une zone imprimée protégée par un capot de protection transparent permet d'ajouter au dispositif une fonction d'identification de l'article sécurisé.The incorporation in the antitheft device of at least one printed area protected by a transparent protective cover makes it possible to add to the device a function of identification of the secured article.

On notera que ladite au moins une zone imprimée n'est pas nécessairement un élément distinct du capot ou du dispositif. Par exemple, la zone imprimée peut être la face interne du capot en regard de la face externe du dispositif et/ou ladite face externe elle-même contre laquelle est disposé le capot. Ainsi, l'impression est réalisée directement, selon le cas, sur la face interne du capot ou la face externe du dispositif.Note that said at least one printed area is not necessarily a separate element of the hood or the device. For example, the printed area may be the internal face of the cover facing the outer face of the device and / or said outer face itself against which the cover is disposed. Thus, the printing is performed directly, as the case may be, on the inner face of the cover or the outer face of the device.

Selon une caractéristique possible, le dispositif comprend une partie de préhension qui s'étend en éloignement de la zone de serrage, ladite au moins une zone imprimée protégée par le capot de protection transparent étant portée par la partie de préhension.According to a possible feature, the device comprises a gripping portion which extends away from the clamping zone, said at least one printed zone protected by the transparent protective cover being carried by the gripping portion.

Cette partie de préhension confère au dispositif une surface relativement étendue qui se prête particulièrement bien à l'intégration d'une ou de plusieurs zones imprimées.This gripping portion gives the device a relatively large area which is particularly well suited to the integration of one or more printed areas.

On notera que cette partie de préhension peut être conforme à celle décrite dans le premier aspect de l'invention et qui permet, lors d'une traction exercée sur celle-ci, d'augmenter la pression de serrage exercée sur l'article à protéger ou son emballage.Note that this gripping portion may be in accordance with that described in the first aspect of the invention and that, during a tension exerted on it, to increase the clamping pressure exerted on the article to be protected or its packaging.

A cet effet, la partie est susceptible de se déplacer d'une position rapprochée vers une position éloignée de la zone de serrage sous l'action d'un effort de traction externe au dispositif, le dispositif comprenant au moins un élément de liaison mobile relié à l'un des organes de serrage et qui est entrainé en mouvement lors du mouvement d'éloignement de la partie de préhension, tendant ainsi à déplacer l'organe de serrage auquel il est relié en direction de l'autre organe de serrage, afin d'enserrer l'article ou son emballage avec une deuxième pression de serrage supérieure à la première pression de serrage.For this purpose, the part is likely to move from a close position to a position remote from the clamping zone under the action of a traction force external to the device, the device comprising at least one connected mobile connection element to one of the clamping members and which is driven in motion during the movement away from the gripping portion, thereby tending to move the clamping member to which it is connected in the direction of the other clamping member, so as to clamping the article or its packaging with a second clamping pressure greater than the first clamping pressure.

Selon une autre caractéristique possible, prise de façon alternative ou en combinaison avec la précédente, la partie de commande de serrage comprend une molette rotative d'actionnement, ladite au moins une zone imprimée protégée par le capot de protection transparent étant portée par la partie supérieure de la molette.According to another possible characteristic, taken alternatively or in combination with the preceding one, the clamping control part comprises a rotary actuating wheel, the said at least one printed area protected by the transparent protective cover being carried by the upper part. of the wheel.

Cette partie ou région du dispositif orientée vers le haut est particulièrement visible de l'extérieur du dispositif et se prête donc particulièrement bien à l'intégration d'au moins une zone imprimée protégée par un capot de protection transparent.This portion or region of the upwardly facing device is particularly visible from the outside of the device and is therefore particularly suitable for the integration of at least one printed area protected by a transparent protective cover.

En effet, le capot de protection transparent est alors agencé en vis-à-vis de la face supérieure de la partie supérieure de la molette et la zone imprimée peut par exemple prendre la forme d'un jeton ou disque imprimé aménagé dans un logement cylindrique évidé (ouvert vers le haut) situé dans la partie supérieure de la molette.Indeed, the transparent protective cover is then arranged vis-à-vis the upper face of the upper part of the wheel and the printed area may for example take the form of a token or printed disc arranged in a cylindrical housing recessed (open upwards) located in the upper part of the wheel.

Alternativement, la zone imprimée peut être la face interne du capot disposée en vis-à-vis de la face supérieure de la molette ou peut être la face supérieure de la molette elle-même.Alternatively, the printed area may be the inner face of the cover disposed vis-à-vis the upper face of the wheel or may be the upper face of the wheel itself.

On notera que l'intégration d'au moins une zone imprimée protégée par un capot de protection transparent dans la partie de commande de serrage du dispositif, de façon générale, et, par exemple, dans la molette rotative d'actionnement, permet d'apporter une nouvelle fonction au dispositif sans augmenter son encombrement.Note that the integration of at least one printed area protected by a transparent protective cover in the clamping control portion of the device, in general, and, for example, in the rotary wheel actuation, allows to bring a new function to the device without increasing its size.

La compacité du dispositif est ainsi plus grande qu'avec une partie de préhension qui s'étend en éloignement de la zone de serrage et qui donc, nécessairement, augmente l'encombrement.The compactness of the device is thus greater than with a gripping portion which extends away from the clamping zone and which, therefore, necessarily increases the bulk.

Par ailleurs, le dispositif selon le premier aspect de l'invention peut également comporter au moins une zone imprimée protégée par un capot de protection transparent conformément au troisième aspect exposé ci-dessus.Furthermore, the device according to the first aspect of the invention may also comprise at least one printed area protected by a transparent protective cover according to the third aspect described above.

Les caractéristiques et avantages présentés ci-dessus à propos du troisième aspect de l'invention sont également applicables au dispositif selon le premier aspect.The features and advantages presented above with respect to the third aspect of the invention are also applicable to the device according to the first aspect.

On notera toutefois que chacun des trois aspects mentionnés ci-dessus peut être considéré isolément.It should be noted, however, that each of the three aspects mentioned above can be considered in isolation.

Un dispositif antivol selon l'invention est destiné à être accroché, comme on le verra plus tard, à un article qui doit être sécurisé contre le vol. Il peut s'agir par exemple d'un article ou produit commercial et qui est donc susceptible d'être vendu en magasin. Alternativement, il peut s'agir d'un article ou objet destiné à être exposé dans un lieu public ou privé.An antitheft device according to the invention is intended to be hooked, as will be seen later, to an article that must be secured against theft. It may be for example an article or commercial product and is therefore likely to be sold in stores. Alternatively, it may be an article or object intended to be displayed in a public or private place.

Un tel dispositif est représenté sur les Figures 1 à 3 . Such a device is represented on the Figures 1 to 3 .

Le dispositif 1 comprend, d'un point de vue fonctionnel, une partie de commande de serrage 6 qui est actionnable par un utilisateur (ce dernier peut exercer un effort sur la partie de commande) et deux organes de serrage 2 et 3 disposés en vis-à-vis et qui sont destinés à enserrer un article à protéger.The device 1 comprises, from a functional point of view, a clamping control part 6 which can be actuated by a user (the latter can exert a force on the control part) and two clamping members 2 and 3 arranged in a screw vis-à-vis and which are intended to enclose an article to protect.

L'article est placé entre les deux organes de serrage dans une zone dite de serrage S et l'actionnement de la partie de commande de serrage 6 par un utilisateur provoque le déplacement d'au moins un des deux organes de serrage en direction de l'autre. Ces deux organes de serrage constituent en quelque sorte des moyens d'accrochage du dispositif sur l'article.The article is placed between the two clamping members in a so-called clamping zone S and the actuation of the clamping control part 6 by a user causes the displacement of at least one of the two clamping members in the direction of the clamping member. 'other. These two clamping members are in a manner of attachment means of the device on the article.

Dans le mode de réalisation détaillé ci-après seul l'un des deux organes de serrage est déplacé par la partie de commande, l'autre organe n'étant pas déplacé par celle-ci.In the embodiment detailed below only one of the two clamping members is moved by the control part, the other member is not moved by it.

Selon une variante non représentée, les deux organes sont déplacés l'un vers l'autre par la partie de commande.According to a variant not shown, the two members are moved towards one another by the control part.

On notera que le déplacement d'au moins un organe de serrage a lieu, ici, selon une direction axiale Z qui correspond, par exemple sur les Figures, à la direction verticale. Le mouvement est ainsi rectiligne.It will be noted that the displacement of at least one clamping member takes place here in an axial direction Z which corresponds, for example in the Figures, to the vertical direction. The movement is thus straight.

Selon une variante non représentée, la direction du déplacement peut être curviligne.According to a variant not shown, the direction of movement can be curvilinear.

Les articles auxquels le dispositif 1 est accroché ou fixé peuvent être de nature diverse. Il peut s'agir par exemple de textiles fragiles tels que des cravates, foulards, écharpes, d'articles de maroquinerie tels que sacs, ceintures, de chaussures, de lunettes, d'articles de sport (clubs de golf...), de bouteilles...The articles to which the device 1 is hooked or fixed may be of various nature. It may be for example fragile textiles such as ties, scarves, scarves, leather goods such as bags, belts, shoes, glasses, sporting goods (golf clubs ...), bottles ...

On notera que la partie dite d'enserrage ou d'accrochage dans laquelle est introduit l'article peut être ouverte comme c'est le cas sur la Figure 3 . Le dispositif fonctionne alors comme une pince munie de deux mâchoires de serrage.It will be noted that the so-called gripping or hooking part into which the article is introduced can be opened as is the case on the Figure 3 . The device then functions as a clamp provided with two clamping jaws.

Alternativement, la partie d'enserrage ou d'accrochage peut être fermée, formant ainsi une sorte de cadre périphérique entourant la zone de serrage.Alternatively, the gripping or hooking portion may be closed, thus forming a kind of peripheral frame surrounding the clamping zone.

Selon la nature de l'article, l'un ou l'autre des types de dispositifs présentés ci-dessus est utilisé.Depending on the nature of the article, any of the types of devices presented above is used.

On va maintenant décrire les différents éléments constitutifs de la partie de commande de serrage représentés sur les Figures 1 à 3 . The various components of the tightening control portion shown in the drawings will now be described. Figures 1 to 3 .

Le dispositif antivol 1 comprend deux demi-fourreaux 4a et 4b qui sont rendues solidaires l'une de l'autre par exemple à l'aide de tétons non représentés, disposés transversalement en saillie suivant le plan de jointure sur l'une des demi-fourreaux et alignés avec des trous non représentés, disposés transversalement suivant le plan de jointure sur l'autre demi-portion. Cette liaison mécanique est maintenue de façon définitive par exemple par un procédé de soudure par ultrasons.The antitheft device 1 comprises two half-sleeves 4a and 4b which are secured to each other for example by means of not shown pins, arranged transversely projecting along the joint plane on one of the half sleeves and aligned with holes not shown, arranged transversely along the joint plane on the other half-portion. This mechanical connection is permanently maintained for example by an ultrasonic welding process.

D'autres systèmes d'assemblage des demi-fourreaux sont envisageables.Other systems for assembling the half-sleeves are conceivable.

Les demi-fourreaux 4a et 4b réunies forment une pièce fixe 4 qui entoure l'organe de serrage 2 mobile en translation.The half-sleeves 4a and 4b together form a fixed part 4 which surrounds the clamping member 2 movable in translation.

L'organe de serrage comporte un support 2a qui comprend une portion cylindrique 2a1 creuse, filetée à l'intérieur et qui se termine à son extrémité non ouverte par une tête d'accrochage 2a2. L'organe de serrage 2 comporte également un élément de contact 2b qui recouvre la tête d'accrochage à la façon d'un capuchon. Une description plus détaillée de l'organe de serrage 2 sera effectuée ultérieurement en référence aux Figures The clamping member comprises a support 2a which comprises a hollow cylindrical portion 2a1 threaded on the inside and which ends at its unopened end by a fastening head 2a2. The clamping member 2 also comprises a contact element 2b which covers the fastening head in the manner of a cap. A more detailed description of the clamping member 2 will be performed later with reference to FIGS.

4a-b et 5.4a-b and 5.

Comme représenté sur les Figures 1 et 3, la partie de commande 6 du dispositif antivol 1 selon l'invention comprend également une came 9 et une molette d'actionnement 21 assurant les liaisons mécaniques avec l'organe de serrage 2.As shown on Figures 1 and 3 , the control part 6 of the antitheft device 1 according to the invention also comprises a cam 9 and an actuating wheel 21 providing mechanical connections with the clamping member 2.

La came 9, de forme sensiblement cylindrique, possède une portion annulaire 9a en forme de disque et une portion filetée 9b. La portion annulaire 9a est destinée à évoluer dans une gorge annulaire interne 11a formée par la réunion des deux demi-fourreaux 4a, 4b, tandis que la portion filetée est introduite dans la portion cylindrique 2a1 creuse et filetée de l'organe de serrage 2. Cette portion annulaire 9a est introduite dans la gorge annulaire 11 a au moment de la réunion des deux demi-fourreaux 4a et 4b.The cam 9, of substantially cylindrical shape, has a disk-shaped annular portion 9a and a threaded portion 9b. The annular portion 9a is intended to evolve in an internal annular groove 11a formed by the union of the two half-sleeves 4a, 4b, while the threaded portion is introduced into the hollow cylindrical portion 2a1 and threaded of the clamping member 2. This annular portion 9a is introduced into the annular groove 11a at the time of the meeting of the two half-sleeves 4a and 4b.

Il est entendu ici qu'une came est une pièce mécanique transformant un mouvement rotatif en un mouvement de translation.It is understood here that a cam is a mechanical part transforming a rotary movement into a translational movement.

Une pièce de maintien 8 comprend une portion cylindrique 8a et une portion circulaire 8b formant un épaulement externe par rapport à la portion cylindrique et présentant un rebord ou épaulement interne 8c de diamètre sensiblement égal au diamètre extérieur des deux demi-fourreaux 4a, 4b réunies. La pièce 8 est introduite en force par le haut sur la pièce formée de la réunion des deux demi-fourreaux 4a, 4b. Deux languettes ou lamelles élastiques 7a, 7b sont respectivement aménagées sur les demi-fourreaux 4a, 4b et font saillie vers l'extérieur par rapport à la surface externe de celles-ci. Ainsi, lors du montage en force de la pièce de maintien 8 autour de la pièce 4a, 4b (fourreau), le rebord interne 8c glisse sur les languettes et, du fait de leur élasticité, les déforme vers l'intérieur des demi-fourreaux. Après le passage du rebord interne au-delà de l'extrémité libre des languettes, celles-ci reviennent dans leur position initiale. Comme le diamètre externe des demi-fourreaux 4a, 4b avec les languettes 7a, 7b est supérieur au diamètre interne de la pièce 8 à l'endroit de son rebord interne 8c, la pièce 8 ne peut plus remonter. La pièce de maintien 8 est ainsi retenue par les languettes (moyens de retenue) sur la pièce 4a, 4b, empêchant également la séparation des deux demi-pièces 4a, 4b.A holding part 8 comprises a cylindrical portion 8a and a circular portion 8b forming an external shoulder with respect to the cylindrical portion and having an internal flange or shoulder 8c of diameter substantially equal to the outer diameter of the two half-sleeves 4a, 4b joined. The part 8 is forced in force from above onto the part formed by the union of the two half-sleeves 4a, 4b. Two tabs or elastic strips 7a, 7b are respectively provided on the half-sleeves 4a, 4b and project outwardly relative to the outer surface thereof. Thus, during the mounting force of the holding piece 8 around the part 4a, 4b (sheath), the inner flange 8c slides on the tongues and, because of their elasticity, deforms them towards the inside of the half-sleeves . After the passage of the inner rim beyond the free end of the tongues, they return to their original position. As the outer diameter of the half-sleeves 4a, 4b with the tongues 7a, 7b is greater than the internal diameter of the part 8 at the location of its inner flange 8c, the part 8 can not go up. The holding piece 8 is thus retained by the tongues (retaining means) on the part 4a, 4b, also preventing the separation of the two half-pieces 4a, 4b.

La came 9 possède sur sa partie supérieure un logement 12a coaxial destiné accueillir dans sa totalité un doigt 13.The cam 9 has on its upper part a coaxial housing 12a for accommodating in its entirety a finger 13.

Le doigt 13 est métallique (notamment magnétique) et possède sur une de ses deux extrémités un élément en saillie 13a lui permettant d'être disposé coaxialement à un orifice traversant de la came 9 ménagé selon son axe de rotation. Sur l'autre extrémité du doigt 13 se trouve une portion rectangulaire 13b dans laquelle est ménagé un logement 14a pour accueillir un ressort de compression hélicoïdal 14. Cette extrémité opposée du doigt prend la forme d'une fourche. Une fois le dispositif antivol 1 monté, ce ressort 14 se trouve au repos ou bien comprimé entre le fond du logement 14a ménagé dans la portion rectangulaire 13b du doigt 13 et un évidement 14b pratiqué sur le carter 18 (sur une face interne) de la partie de commande 2.The finger 13 is metallic (in particular magnetic) and has on one of its two ends a projecting element 13a allowing it to be arranged coaxially with a through hole of the cam 9 formed along its axis of rotation. On the other end of the finger 13 is a rectangular portion 13b in which is formed a housing 14a to accommodate a helical compression spring 14. This opposite end of the finger takes the form of a fork. Once the antitheft device 1 is mounted, this spring 14 is at rest or compressed between the bottom of the housing 14a formed in the rectangular portion 13b of the finger 13 and a recess 14b formed on the housing 18 (on an inner face) of the control part 2.

Coaxialement à cet évidement 14b, est aménagé sur la face interne du carter 18 un logement 12b de forme complémentaire à la forme rectangulaire de la portion rectangulaire 13b du doigt 13 pour l'insertion de ce dernier dans ledit logement 12b.Coaxially with this recess 14b, is arranged on the inner face of the housing 18 a housing 12b of shape complementary to the rectangular shape of the rectangular portion 13b of the finger 13 for the insertion of the latter in said housing 12b.

L'ensemble comprenant le doigt 13, le logement 12a sur la came 9, le logement 14a sur le doigt 13, le ressort 14, l'évidement 14b et le logement 12b sur le carter 18 constitue un mécanisme d'embrayage 24 pour le dispositif antivol 1.The assembly comprising the finger 13, the housing 12a on the cam 9, the housing 14a on the finger 13, the spring 14, the recess 14b and the housing 12b on the housing 18 constitutes a clutch mechanism 24 for the device antitheft 1.

Coaxialement à ce mécanisme d'embrayage 24, un mécanisme de transmission avec contrôleur de couple est disposé dans la partie de commande 6 du dispositif antivol 1.Coaxially with this clutch mechanism 24, a transmission mechanism with a torque controller is arranged in the control part 6 of the antitheft device 1.

Ce mécanisme de transmission comprend une partie 16 de la came 9 en forme de S ménagée sur celle-ci de façon monobloc, et une couronne 17 disposée entre la came 9 et le carter 18.This transmission mechanism comprises a portion 16 of the S-shaped cam 9 formed thereon integrally, and a ring 17 disposed between the cam 9 and the housing 18.

Les deux extrémités 16a de la partie 16 en forme de S sont flexibles suivant le plan du S et pourvues chacune d'une portion 19a en dents de scie. Le plan du S est, dans les exemples décrits, perpendiculaire à l'axe de rotation de la came.The two ends 16a of the S-shaped portion 16 are flexible along the S plane and each provided with a sawtooth portion 19a. The plane of S is, in the examples described, perpendicular to the axis of rotation of the cam.

La couronne 17 possède, sur son contour intérieur 19b, une forme en dents de scie dont les dents ont une forme complémentaire de celles des portions 19a, et, sur son contour extérieur des éléments en saillie 20a, par exemple, en forme de trapèzes rectangles disposés sur des branches flexibles transversalement au plan de la couronne 17. Cette configuration est illustrée aux Figures 1 et 2 mais les éléments en saillie 20a peuvent avoir une autre forme et être disposés différemment sur la couronne 17.The ring 17 has, on its inner contour 19b, a sawtooth shape whose teeth have a shape complementary to those of the portions 19a, and on its outer contour of the projecting elements 20a, for example, in the form of rectangular trapezoids arranged on flexible branches transversely to the plane of the crown 17. This configuration is illustrated in FIGS. Figures 1 and 2 but the protruding elements 20a may have another shape and be arranged differently on the ring 17.

Un logement 18a aménagé sur la face interne du carter 18 autorise le mouvement coaxial de la couronne 17 avec la partie 16 de la came 9 en forme de S.A housing 18a arranged on the inner face of the housing 18 allows the coaxial movement of the ring 17 with the portion 16 of the cam 9 in the shape of S.

Ce mouvement est arrêté selon un sens de rotation par des éléments en saillie 20b, eux aussi de forme trapézoïdale rectangle, aménagés sur le carter 18 sur la trajectoire des éléments en saillie 20a trapézoïdaux rectangles disposés sur les branches flexibles de la couronne 17.This movement is stopped in a direction of rotation by projecting elements 20b, also of trapezoidal rectangle shape, arranged on the housing 18 on the trajectory of the protruding rectangular trapezoidal elements 20a arranged on the flexible branches of the ring 17.

Les éléments trapézoïdaux rectangles du carter 18 et de la couronne 17 sont disposés en opposition de telle sorte que les pentes de deux trapèzes rectangles se rencontrent selon un sens de rotation, permettant ainsi aux branches de la couronne 17 de fléchir et à la couronne de tourner.The trapezoidal rectangular elements of the housing 18 and the ring 17 are arranged in opposition so that the slopes of two right trapezes meet in a direction of rotation, thus allowing the branches of the ring 17 to bend and the crown to turn. .

Dans l'autre sens de rotation, les côtés rectangulaires des trapèzes se rencontrent, empêchant ainsi la flexion des branches de la couronne 17 et donc la rotation de celle-ci.In the other direction of rotation, the rectangular sides of the trapeziums meet, thus preventing flexing of the branches of the ring 17 and thus the rotation thereof.

Alternativement, on notera que d'autres éléments fixés à la couronne 17, d'une part, et au carter 18 (face interne), d'autre part, peuvent remplir les mêmes fonctions d'engrènement dans un sens de rotation (la couronne et le carter étant liés en rotation) et de rotation l'un par rapport à l'autre dans le sens opposé.Alternatively, it will be noted that other elements attached to the ring 17, on the one hand, and to the casing 18 (internal face), on the other hand, can fulfill the same meshing functions in a direction of rotation (the crown and the housing being rotatably connected) and rotated relative to each other in the opposite direction.

On notera que la molette d'actionnement 21 est fermée sur sa partie arrière par le carter 18.Note that the actuating knob 21 is closed on its rear part by the casing 18.

Le carter vient en appui sur le bord périphérique externe de la portion 8b et y est fixé par exemple par soudage aux ultrasons. De façon générale, l'accès à l'intérieur de la partie de commande 6 est rendu inviolable en solidarisant par exemple entre eux les éléments visibles de l'extérieur par un procédé de soudage par ultrasons.The housing bears on the outer peripheral edge of the portion 8b and is fixed there for example by ultrasonic welding. In general, access to the interior of the control part 6 is made tamperproof by for example joining together the elements visible from the outside by an ultrasonic welding process.

Des creux 21 a sont réalisés sur le contour extérieur de la molette 21 pour positionner les doigts d'un utilisateur (surface de contact ou d'actionnement), afin d'en faciliter la préhension et l'application d'un couple de forces de serrage.Hollow 21a are made on the outer contour of the wheel 21 for positioning the fingers of a user (contact or actuating surface), to facilitate gripping and application of a torque of clamping forces.

Il est également possible d'adjoindre à la molette 21 un dispositif d'affichage (non représenté) présentant une surface d'affichage ou d'impression de taille voisine de celle de la molette 21 et permettant la visualisation d'informations complémentaires sur l'article protégé par le dispositif antivol 1 selon l'invention. La surface d'affichage est par exemple agencée sur le dessus de la partie bombée (forme de calotte) du carter de la molette.It is also possible to add to the wheel 21 a display device (not shown) having a display surface or printing size close to that of the wheel 21 and for viewing additional information on the article protected by the anti-theft device 1 according to the invention. The display surface is for example arranged on the top of the curved portion (cap shape) of the casing of the wheel.

Le dispositif antivol 1 comporte également un ou plusieurs organes, par exemple passifs, c'est-à-dire que ces organes sont aptes à recevoir des ondes électromagnétiques provenant d'une source extérieure au dispositif.The antitheft device 1 also comprises one or more organs, for example passive, that is to say that these organs are able to receive electromagnetic waves from a source external to the device.

Comme représenté sur la Figure 3, le dispositif comprend un organe 23 dissimulé à l'intérieur de la partie de commande 6 et, plus particulièrement, du carter 18 de cette dernière.As shown on the Figure 3 , the device comprises a member 23 hidden inside the control portion 6 and, more particularly, the housing 18 of the latter.

L'organe représenté ici prend, par exemple, la forme d'un circuit résonnant de type LC.The member shown here takes, for example, the form of a resonant circuit LC type.

De façon alternative, le dispositif peut renfermer un ou plusieurs organes actifs (ex circuits RFID), c'est-à-dire des organes qui sont susceptibles d'émettre et de recevoir des ondes électromagnétiques vers l'extérieur du dispositif.Alternatively, the device may contain one or more active members (eg RFID circuits), that is to say bodies that are capable of emitting and receiving electromagnetic waves to the outside of the device.

On notera que de tels organes actifs ou passifs sont, par exemple des bobines avec ferrite avec ou sans condensateur, des circuits LCR, des filaments magnétiques, des circuits de type RFID dotés d'une puce à mémoire active ou passive...It will be noted that such active or passive members are, for example ferrite coils with or without a capacitor, LCR circuits, magnetic filaments, RFID type circuits equipped with an active or passive memory chip ...

Ce ou ces organes coopèrent via la transmission d'ondes électromagnétiques avec un système de détection, tel qu'un portique, une antenne ou un lecteur RFID portatif placé à un point d'accès du magasin où est mis en vente le ou les articles à protéger afin de déclencher une alarme de détection du dispositif antivol au niveau du point d'accès et/ou transmettre une information (par exemple, dans le but d'identifier l'article).This or these bodies cooperate via the transmission of electromagnetic waves with a detection system, such as a gantry, an antenna or a portable RFID reader placed at an access point of the store where is sold the item or items to protect to trigger an anti-theft device detection alarm at the access point and / or transmit information (for example, for the purpose of identifying the item).

Comme représenté sur la Figure 3, l'organe de sécurité est logé dans une région annulaire disposée entre la face interne de la paroi du carter 18 et la portion cylindrique 8a de la pièce de maintien 8.As shown on the Figure 3 , the security organ is housed in an annular region disposed between the inner face of the housing wall 18 and the cylindrical portion 8a of the holding piece 8.

D'autres formes de pièces 8 et de carter 18 permettant d'accueillir des formes différentes d'organes actifs ou passifs de sécurité sont bien entendu envisageables.Other forms of parts 8 and housing 18 to accommodate different forms of active or passive security organs are of course conceivable.

Par ailleurs, d'autres parties du dispositif, telles que le logement 46f, 48f sont également susceptibles d'accueillir de tels organes. Ceci permet au dispositif d'être compatible avec plusieurs technologies de portiques antivol.Furthermore, other parts of the device, such as the housing 46f, 48f are also likely to accommodate such bodies. This allows the device to be compatible with several anti-theft gantry technologies.

Le dispositif antivol selon l'invention comprend également une partie de préhension 40 qui forme une partie saillante par rapport à la partie 6 de commande de serrage.The antitheft device according to the invention also comprises a gripping portion 40 which forms a protruding portion relative to the clamping control portion 6.

Cette partie saillante s'étend en éloignement de l'axe Z dans une direction perpendiculaire à celui-ci.This projecting portion extends away from the Z axis in a direction perpendicular thereto.

La partie de préhension 40 forme une extension radiale par rapport à l'axe de la partie 6 de commande de serrage.The gripping portion 40 forms a radial extension relative to the axis of the clamping control portion 6.

La partie de préhension 40 comprend, de façon générale, plusieurs éléments qui, une fois réunis comme illustré sur la Figure 3 , confèrent au dispositif une forme ouverte en U sous la partie de commande de serrage 6.The gripping portion 40 generally comprises a plurality of elements which, once assembled as illustrated in FIG. Figure 3 , give the device an open U-shape under the clamping control part 6.

Cette forme en U présente une ouverture 42 par laquelle un article est introduit afin d'être positionné dans la zone de serrage S.This U-shaped shape has an opening 42 through which an article is introduced to be positioned in the clamping zone S.

Plus particulièrement, comme représenté sur les Figures 1 et 2 , la partie de préhension 40 comprend un bloc central fixe 44 de part et d'autre duquel sont fixés deux demi-coques ou demi-boîtiers 46 et 48 qui forment ainsi un boîtier ou une coque externe de protection dont les surfaces externes lisses et courbes sont destinées à être manipulées par les utilisateurs.In particular, as shown in Figures 1 and 2 , the gripping portion 40 comprises a fixed central block 44 on either side of which are fixed two half-shells or half-housings 46 and 48 which thus form a casing or an outer protective shell whose smooth and curved outer surfaces. are intended to be manipulated by users.

Le bloc central 44 comprend, de façon générale, deux parties parallèles entre elles 50, 52 dont la base ou jonction est réunie par un bras de liaison 54 perpendiculaire entre ces deux parties. Ce bras présente un logement ouvert du côté opposé à celui visible sur la Figure 1 . The central block 44 comprises, in general, two mutually parallel parts 50, 52 whose base or junction is joined by a connecting arm 54 perpendicular between these two parts. This arm has an open housing on the side opposite to that visible on the Figure 1 .

Les deux parties en forme de U sont visibles en regardant le bloc de côté.The two U-shaped parts are visible by looking at the side block.

Les parties 50 et 52 sont réunies chacune à leur extrémité supérieure et à leur extrémité inférieure qui sont alignées l'une par rapport à l'autre suivant l'axe Z.Parts 50 and 52 are each joined at their end upper and lower end which are aligned with each other along the axis Z.

A leur partie supérieure, les deux parties 50 et 52 se rejoignent pour former une pièce en forme de fourche dont les deux bras ouverts 50a et 52a viennent s'insérer dans une collerette externe 7c pratiquée en partie inférieure de la pièce 4 ( Figures 1 et 3 ). At their upper part, the two parts 50 and 52 meet to form a fork-shaped part whose two open arms 50a and 52a are inserted into an outer collar 7c made in the lower part of the part 4 ( Figures 1 and 3 ).

Les deux bras sont par exemple fixés à cette collerette par exemple par emboîtement et/ou collage.The two arms are for example fixed to this collar, for example by interlocking and / or bonding.

A leur partie inférieure, les deux parties 50 et 52 sont également réunies en formant un socle 55 plus particulièrement visible sur la Figure 2 . At their lower part, the two parts 50 and 52 are also joined together forming a base 55 that is more particularly visible on the Figure 2 .

Ce socle est situé à distance de la base des pièces en forme de U afin de ménager une ouverture 56 permettant l'insertion par l'arrière d'un élément de liaison mobile qui sera décrit ultérieurement, notamment en référence aux Figures 6 à 9.This base is located at a distance from the base of the U-shaped pieces so as to provide an opening 56 allowing insertion from the rear of a movable connecting element which will be described later, in particular with reference to the Figures 6 to 9 .

On notera que le bloc 44 est une pièce monobloc métallique (amagnétique).Note that the block 44 is a single piece metal (non-magnetic).

Les deux demi-boîtiers ou demi-coques 46 et 48 sont symétriques l'une de l'autre et présentent chacune plusieurs portions évidées (formant des compartiments) orientées en vis-à-vis, de manière à pouvoir s'assembler de part et d'autre du bloc central 44.The two half-housings or half-shells 46 and 48 are symmetrical to each other and each have several recessed portions (forming compartments) oriented vis-à-vis, so that they can be assembled from each other. other central block 44 .

Chacun des demi-boîtiers 46, 48 présente, vu de l'extérieur, une forme générale du type comprenant une base 46a, 48a à partir de laquelle s'étendent de façon parallèle deux bras, un bras supérieur 46b, 48b et un bras inférieur 46c, 48c plus court que le bras supérieur.Each of the half-housings 46, 48 has, from the outside, a general shape of the type comprising a base 46a, 48a from which two arms, an upper arm 46b, 48b and a lower arm extend in parallel. 46c, 48c shorter than the upper arm.

Les bras inférieurs sont rectilignes et parallèles l'un avec l'autre tandis que les bras supérieurs sont recourbés au niveau de leur extrémité en direction l'un de l'autre et sont creux de manière à ce que les deux bras 50a et 52a du bloc central puissent s'y insérer.The lower arms are straight and parallel to each other while the upper arms are curved at their end towards each other and are hollow so that the two arms 50a and 52a of the central block can be inserted.

Les deux demi-boîtiers sont évidés comme déjà mentionné ci-dessus afin de recevoir le bloc 44 et les dimensions internes de ces boîtiers sont supérieures aux dimensions (au moins dans le sens de la longueur) du bloc 44 afin d'autoriser un mouvement de translation relatif entre ledit bloc et lesdits demi-boîtiers. Le bloc 44 fixe sert ainsi de support ou de guide lors du mouvement de la partie de préhension.The two half-housings are recessed as already mentioned above to receive the block 44 and the internal dimensions of these housings are greater than the dimensions (at least in the length sense) of the block 44 to allow a movement of relative translation between said block and said half cases. The fixed block 44 thus serves as a support or guide during the movement of the gripping portion.

On notera à cet égard que les évidements ou rainures 46d et 48d autorisent un mouvement relatif entre les bras 50a et 52a du bloc 44 et ces derniers.It should be noted in this regard that the recesses or grooves 46d and 48d allow relative movement between the arms 50a and 52a of the block 44 and the latter.

Par ailleurs, deux supports centraux 46e et 48e respectivement fixés à l'intérieur de chaque demi-boîtier dans sa base, sont destinés à s'insérer à l'intérieur du U formé par les deux parties 50 et 52 du bloc central 44. Les supports 46e, 48e sont fixés l'un à l'autre par leur extrémité libre, de même que les extrémités libres respectives des deux bras 46b et 48b, par exemple par un procédé de soudage aux ultrasons.In addition, two central supports 46e and 48e respectively fixed inside each half-housing in its base, are intended to be inserted inside the U formed by the two parts 50 and 52 of the central block 44. supports 46e, 48e are fixed to each other by their free end, as well as the respective free ends of the two arms 46b and 48b, for example by an ultrasonic welding process.

On notera que les supports 46e et 48e ont une forme incurvée adaptée à la forme interne des bras 50 et 52.It will be noted that the supports 46e and 48e have a curved shape adapted to the internal shape of the arms 50 and 52.

En outre, un organe 60 est destiné à s'insérer dans deux évidements/compartiments 46f et 48f de chacun des demi-boîtiers. Cet organe est par exemple un autre type d'organe passif utilisé pour la détection antivol (par exemple un circuit de type LCR ou ferrite). Alternativement, l'organe 60 pourrait être actif.In addition, a member 60 is intended to be inserted into two recesses / compartments 46f and 48f of each of the half-housings. This member is for example another type of passive member used for antitheft detection (for example a LCR or ferrite type circuit). Alternatively, the member 60 could be active.

On notera à cet égard qu'une cavité (non représentée) de forme correspondante à celle de l'élément saillant 60a est prévue au fond de chaque évidement 46f, 48f.It will be noted in this regard that a cavity (not shown) of a shape corresponding to that of the projecting element 60a is provided at the bottom of each recess 46f, 48f.

Avant de refermer les deux demi-boîtiers 46 et 48 autour du bloc 44 et de la pièce 4, un élément de liaison mobile 70 est inséré par l'arrière du bloc 44 à travers l'ouverture 56.Before closing the two half-housings 46 and 48 around the block 44 and the part 4, a movable connecting element 70 is inserted through the rear of the block 44 through the opening 56.

Cet élément représenté en perspective sur la Figure 1 a la forme générale d'une pelle dont l'extrémité du manche est recourbée vers le haut, dont l'extrémité opposée est plate et est destinée à reposer sur la surface supérieure évidée du socle 55 comme représenté sur la Figure 3 . This element represented in perspective on the Figure 1 has the general shape of a shovel whose end of the handle is curved upwards, the opposite end is flat and is intended to rest on the recessed upper surface of the base 55 as shown on the Figure 3 .

Plus particulièrement, l'élément de liaison 70 comprend une première portion 72 qui forme l'extrémité plane de la pelle et qui porte le deuxième organe de serrage.More particularly, the connecting element 70 comprises a first portion 72 which forms the flat end of the blade and which carries the second clamping member.

L'élément de liaison 70 comprend également une deuxième portion distante qui est constituée par l'extrémité opposée courbe relevée 74 de la pelle. Cette extrémité a une forme de bec.The connecting element 70 also comprises a second portion remote which is constituted by the opposite end curved curve 74 of the shovel. This end has a bill shape.

La forme incurvée en vue de côté de cet élément de liaison correspond à la courbure des deux demi-boîtiers 46 et 48 et notamment de la partie creuse située dans la base de ces derniers.The curved shape in side view of this connecting element corresponds to the curvature of the two half-housings 46 and 48 and in particular of the hollow portion located in the base thereof.

Lorsque l'élément de liaison 70 est installé à l'intérieur des deux demi-boîtiers il occupe la position représentée sur la Figure 3 . When the connecting element 70 is installed inside the two half-housings it occupies the position represented on the Figure 3 .

Dans cette position, la deuxième portion 74 de l'élément de liaison est en contact avec la partie de préhension 40 et, plus particulièrement, avec une portion de paroi 41 située en vis-à-vis.In this position, the second portion 74 of the connecting element is in contact with the gripping portion 40 and, more particularly, with a wall portion 41 located vis-a-vis.

Dans cet exemple, la paroi 41 est celle qui délimite les évidements 46f et 48f.In this example, the wall 41 is the one that delimits the recesses 46f and 48f.

Toutefois, d'autres portions de la partie de préhension 40 peuvent jouer le même rôle que celui de la paroi 41 comme on le verra plus tard.However, other portions of the gripping portion 40 may play the same role as that of the wall 41 as will be seen later.

Comme représenté sur les Figures 2 et 3 , une partie formant un cache 76 est mise en place après l'installation de l'élément de liaison 70 afin d'obturer l'accès à l'intérieur de la partie de préhension 40.As shown on Figures 2 and 3 , a part forming a cover 76 is put in place after the installation of the connecting element 70 in order to block the access inside the gripping portion 40.

Cette portion a une forme incurvée adaptée à la forme des deux demi-boîtiers 46 et 48 ainsi qu'à celle de l'élément de liaison 70.This portion has a curved shape adapted to the shape of the two half-housings 46 and 48 as well as that of the connecting element 70.

On notera par ailleurs que des moyens élastiques 80 sont positionnés dans un logement 82 par exemple de forme cylindrique ( Figure 3 ), aménagée dans le bras de liaison 54, et sont ainsi placés entre le fond de ce logement et les supports centraux 46e et 48e des deux demi-boîtiers (seul le demi-boîtier 46 est visible sur la Figure 3 ). It will also be noted that resilient means 80 are positioned in a housing 82, for example of cylindrical shape ( Figure 3 ), arranged in the connecting arm 54, and are thus placed between the bottom of this housing and the central supports 46e and 48e of the two half-housings (only the half-housing 46 is visible on the Figure 3 ).

Ces moyens élastiques prennent par exemple la forme d'un ressort hélicoïdal de compression.These elastic means take for example the form of a helical compression spring.

Toutefois, plusieurs ressorts pourraient être utilisés simultanément, ou, alternativement, un ou plusieurs autres éléments élastiques tels que des lames ou des lamelles dotées de courbures appropriées.However, several springs could be used simultaneously, or, alternatively, one or more other elastic elements such as blades or slats with appropriate curvatures.

On va maintenant décrire en référence aux Figures 4a -b à 9 la constitution des organes de serrage 2 et 3.We will now describe with reference to Figures 4a -b to 9 the constitution of the clamping members 2 and 3.

L'organe de serrage 2 décrit plus haut comprend le support 2a en forme de piston déjà partiellement décrit et un élément de contact 2b dont la fonction est d'entrer en contact avec un article à protéger qui sera enserré entre les deux organes de serrage.The clamping member 2 described above comprises the support 2a in piston shape already partially described and a contact element 2b whose function is to come into contact with an article to be protected which will be sandwiched between the two clamping members.

Cet élément de contact ne doit pas être lisse car il doit procurer de l'adhérence entre l'article et le dispositif antivol.This contact element must not be smooth because it must provide adhesion between the article and the antitheft device.

Cet élément de contact doit également préserver l'article lors du serrage du dispositif sur ce dernier.This contact element must also preserve the article when tightening the device on the latter.

A cet effet, l'élément de contact est réalisé dans un matériau souple, élastiquement déformable et qui est apte à se déformer au contact avec un article ou son emballage.For this purpose, the contact element is made of a flexible material, elastically deformable and which is able to deform in contact with an article or its packaging.

De plus, l'élément de contact présente une surface extérieure 2b1 bombée ou convexe qui, lors d'un contact avec un objet, se déforme comme la pulpe du doigt d'un adulte, permettant ainsi de répartir sur une relativement grande surface de l'objet une pression élevée sans toutefois abîmer ce dernier.In addition, the contact element has a curved or convex outer surface 2b1 which, when in contact with an object, deforms like the finger pulp of an adult, thus making it possible to distribute over a relatively large area of the body. object a high pressure without damaging it.

Le matériau utilisé est par exemple un élastomère du type caoutchouc ou gomme, notamment de type élastomère thermoplastique, par exemple un produit vendu sous la référence commerciale MAKALEST distribué par la société Maurer Kunststofftechnik.The material used is, for example, an elastomer of the rubber or rubber type, in particular of the thermoplastic elastomer type, for example a product sold under the trade reference MAKALEST distributed by the company Maurer Kunststofftechnik.

Le support 2a, par exemple métallique, comporte au niveau de sa tête 2a2 des zones d'accrochage pour l'accrochage du matériau injecté sous forme liquide lors du processus de moulage par injection.The support 2a, for example metallic, comprises at its head 2a2 attachment zones for the attachment of the injected material in liquid form during the injection molding process.

A cet effet, le support 2a comporte au niveau de la tête (Figures 4a-b) un plateau 2a3 relié au corps central du support par un cylindre ou noyau central 2a4 autour duquel sont répartis, de façon espacée, plusieurs barreaux 2a5, ménageant ainsi un espace périphérique (passage) entre ces derniers et le noyau central 2a4 ainsi qu'entre les barreaux eux-mêmes.For this purpose, the support 2a comprises at the level of the head ( Figures 4a-b ) a plate 2a3 connected to the central body of the support by a central cylinder or core 2a4 around which are distributed, spaced, several bars 2a5, thus providing a peripheral space (passage) between them and the central core 2a4 and between the bars themselves.

Le plateau 2a3 est percé, quant à lui, de plusieurs orifices 2a31 qui traversent ce dernier dans son épaisseur.The plate 2a3 is pierced, meanwhile, several orifices 2a31 which pass through the latter in its thickness.

Ces orifices ainsi que les espaces aménagés entre les barreaux 2a5 et entre ceux-ci et le noyau central 2a4 définissent des passages constituant des zones d'accrochage dans lesquelles le matériau injecté sous forme liquide va pénétrer et s'y accrocher à la suite du refroidissement (solidification).These orifices and the spaces arranged between the bars 2a5 and between these and the central core 2a4 define passages constituting attachment zones in which the material injected in liquid form will penetrate and hang on as a result of the cooling (solidification).

La forme de l'élément de contact obtenue est représentée sur la Figure 5 et se présente comme un capuchon ou coussin de protection aménagé sur la tête d'accrochage du support 2a.The shape of the contact element obtained is represented on the Figure 5 and is in the form of a protective cap or cushion arranged on the fastening head of the support 2a.

Le capuchon présente une base annulaire 2b1 agencée au niveau de la zone du support où se trouvent les barreaux et le noyau central ( Figure 4b ). The cap has an annular base 2b1 arranged at the region of the support where the bars and the central core are located ( Figure 4b ).

Ce capuchon est prolongé par une tête de contact qui s'étend d'abord en s'évasant radialement, puis en convergeant (la tête forme ainsi un épaulement) de façon à constituer la surface bombée 2b1.This cap is extended by a contact head which first extends radially flaring, then converging (the head thus forms a shoulder) so as to form the curved surface 2b1.

Grâce au procédé de moulage par injection et aux zones d'accrochage, le matériau constitutif de l'élément de contact 2b et le support 2a (en forme de piston) forment ainsi une pièce unique.Thanks to the injection molding process and the attachment zones, the material constituting the contact element 2b and the support 2a (in the form of a piston) thus form a single piece.

Ainsi, l'élément de contact est parfaitement solidarisé à son support, ce qui rend très difficile leur séparation.Thus, the contact element is perfectly secured to its support, which makes their separation very difficult.

L'élément de liaison 70 est représenté sur les Figures 6 et 7 et présente à sa partie d'extrémité aplatie en forme de pelle 72 une pluralité de trous perforant l'épaisseur de celle-ci.The connecting element 70 is represented on the Figures 6 and 7 and has at its spade-shaped end portion 72 a plurality of holes perforating the thickness thereof.

On dénombre ainsi par exemple quatre trous 84 répartis de façon équilibrée.For example, there are four holes 84 distributed in a balanced manner.

Les Figures 8 et 9 illustrent l'élément de liaison 70 (par exemple métallique) en forme de pelle portant un élément de contact 86 monté sur l'extrémité aplatie 72 formant support. The Figures 8 and 9 illustrate the shovel-shaped connecting element 70 (for example metal) carrying a contact element 86 mounted on the flattened end 72 forming a support.

Cet élément de contact 86 possède une surface extérieure bombée 86a orientée vers le haut et qui est destinée à entrer en contact avec un article à protéger ou son emballage.This contact element 86 has an upwardly curved outer surface 86a that is intended to come into contact with an article to be protected or its packaging.

Cet élément de contact est réalisé dans le même matériau que l'élément de contact 2b des Figures 4a -b et 5. This contact element is made of the same material as the contact element 2b of the Figures 4a -b and 5.

La mise en place de l'élément de contact 86 sur l'élément de liaison 70 est réalisée également en utilisant un procédé de moulage par injection.The placing of the contact element 86 on the connecting element 70 is also performed using an injection molding process.

Les trous 84 (passages) constituent des zones d'accrochage du matériau injecté sous forme liquide et qui permettent au matériau, après refroidissement (solidification), d'être ancré dans le support 72.The holes 84 (passages) constitute zones of attachment of the injected material in liquid form and which allow the material, after cooling (solidification), to be anchored in the support 72.

On notera que la partie formant support 72 est également évidée par en-dessous, comme représenté sur la Figure 7 , pour permettre au matériau injecté, lors du moulage par injection, de s'y répandre en remplissant cet espace comme illustré, après solidification, sur la Figure 9 . Note that the support portion 72 is also hollowed out from below, as shown in FIG. Figure 7 , to allow the injected material, during injection molding, to spread by filling this space as illustrated, after solidification, on the Figure 9 .

Un contact intime est ainsi obtenu entre l'élément de contact 86 et son support ( Figures 8 et 9 ). Intimate contact is thus obtained between the contact element 86 and its support ( Figures 8 and 9 ).

Les autres caractéristiques et avantages exposés ci-dessus en relation avec les Figures 4a -b et 5 s'appliquent également ici et ne seront donc pas répétés.The other features and advantages set out above in relation to the Figures 4a -b and 5 also apply here and will not be repeated.

L'ensemble de l'élément de contact 86 et de son support 72 forme l'organe de serrage 3 qui est disposé en vis-à-vis de l'organe de serrage 2 sur la Figure 3 . The assembly of the contact element 86 and its support 72 forms the clamping member 3 which is arranged opposite the clamping member 2 on the Figure 3 .

Comme représenté sur les Figures 1 à 3 , le dispositif selon l'invention comporte, de façon optionnelle, un système d'affichage 90 faisant partie de la partie de préhension 40.As shown on Figures 1 to 3 , the device according to the invention comprises, optionally, a display system 90 forming part of the gripping portion 40.

Plus particulièrement, ce système d'affichage 90 est fixé sur les deux demi-boîtiers ou demi-coques 46 et 48, par exemple sur la surface extérieure courbe de leur base 46a, 48a.More particularly, this display system 90 is fixed on the two half-housings or half-shells 46 and 48, for example on the curved outer surface of their base 46a, 48a.

Cette surface extérieure est une surface frontale de la partie de préhension qui n'est généralement pas celle manipulée par l'utilisateur.This outer surface is a front surface of the gripping portion which is not generally that handled by the user.

En effet, généralement, les utilisateurs utilisent de préférence les surfaces latérales planes pour y apposer leurs doigts.Indeed, generally, users preferably use the flat side surfaces to affix their fingers.

La surface frontale convexe se prête donc particulièrement bien à l'intégration d'un système d'affichage.The convex front surface is therefore particularly suitable for the integration of a display system.

Comme représenté sur les Figures, ce système d'affichage a également une forme incurvée correspondant à la courbure de la surface frontale extérieure des demi-boîtiers et possède sensiblement l'allure d'une portion de cylindre de faible épaisseur.As shown in the figures, this display system also has a curved shape corresponding to the curvature of the outer front surface of the half-housings and has substantially the appearance of a thin cylinder portion.

Plus particulièrement, ce système comprend au moins une zone imprimée 92 et qui est protégée par un capot de protection extérieur 94.More particularly, this system comprises at least one printed area 92 and which is protected by an external protective cover 94.

La zone imprimée prend par exemple la forme d'un support d'impression qui peut être une feuille de papier ou une pièce de carton disposée dans un logement pratiqué sur la face interne 94a du capot. Ce dernier est par exemple fixé par collage ou par un procédé de soudage aux ultrasons, à la surface frontale externe des deux demi-boîtiers 46 et 48.The printed area takes for example the form of a printing medium which may be a sheet of paper or a piece of cardboard disposed in a housing made on the inner face 94a of the hood. The latter is for example fixed by gluing or by an ultrasonic welding process, to the external front surface of the two half-housings 46 and 48.

La fixation entre le capot 94 et la surface frontale externe des deux demi-boîtiers est réalisée au niveau du cadre périphérique externe 94b du capot 94 dont seules les parties supérieure et inférieure sont représentées sur la Figure 3 . The fixing between the cover 94 and the external front surface of the two half-housings is carried out at the level of the outer peripheral frame 94b of the cover 94, of which only the upper and lower parts are shown on the Figure 3 .

On notera que d'autres moyens de fixation permanents ou temporaires (par exemple pour permettre de changer l'affichage) du capot 94 à la partie de préhension 40 sont envisageables, de même que d'autres agencements de la zone imprimée 92 et du capot 94.It will be noted that other permanent or temporary fixing means (for example to allow the display to be changed) from the cover 94 to the gripping portion 40 are conceivable, as well as other arrangements of the printed area 92 and the cover 94.

L'avantage de disposer un système d'affichage sur la partie de préhension est de disposer d'une surface relativement étendue, dans une région de la partie de préhension qui ne gène pas la manipulation de cette dernière.The advantage of having a display system on the gripping portion is to have a relatively large area in a region of the gripping portion that does not interfere with handling thereof.

Les inscriptions portées par la zone imprimée du support d'impression 92 peuvent être réalisées par différentes techniques d'impression telles que l'impression laser, la tampographie...The inscriptions carried by the printed area of the print medium 92 can be achieved by various printing techniques such as laser printing, pad printing, etc.

On notera que le capot 94 peut alternativement être fixé de manière amovible (vissé, clipsé, emboîté... ) sur la partie de préhension 40.Note that the cover 94 may alternatively be removably attached (screwed, clipped, fitted ...) on the gripping portion 40.

De façon générale, le capot est en quelque sorte une fenêtre de protection fixée de façon amovible ou permanente sur le dispositif 1. A cet égard, l'ensemble constitué du capot protégeant au moins une zone imprimée (support d'impression) peut alternativement (ou en plus) être agencé sur une autre région du dispositif telle que la face supérieure 21 b de la molette.In general, the cover is in a way a protective window removably or permanently fixed to the device 1. In this respect, the assembly consisting of the cover protecting at least one printed area (print medium) may alternatively ( or in addition) be arranged on another region of the device such as the upper face 21b of the wheel.

Le capot peut être réalisé en matériau transparent de type plastique tel qu'en polycarbonate ou bien en verre ou, de façon plus générale, dans tout autre matériau transparent permettant de fournir une protection contre l'usure, l'humidité et diverses autres agressions.The cover can be made of transparent plastic material such as polycarbonate or glass or, more generally, in any other transparent material to provide protection against wear, moisture and various other attacks.

On notera qu'au moins un élément additionnel portant la zone d'impression peut alternativement être disposé entre le support 92 et la face intérieure du capot 94.It will be noted that at least one additional element carrying the printing zone may alternatively be placed between the support 92 and the inside face of the cover 94.

On va maintenant décrire le fonctionnement du dispositif antivol selon l'invention en référence aux Figures 3 , 10 et 11 . The operation of the antitheft device according to the invention will now be described with reference to the Figures 3 , 10 and 11 .

Tout d'abord, lors de la mise en place du dispositif 1 sur un article protégé l'utilisateur commence par écarter au maximum les organes de serrage 2 et 3 l'un de l'autre pour permettre l'insertion de l'article dans l'ouverture 42 ( Figure 3 ). Firstly, when setting up the device 1 on a protected article, the user starts by spreading the clamping members 2 and 3 as far as possible from one another to allow insertion of the article into the opening 42 ( Figure 3 ).

En d'autres termes, les organes de serrage (moyens d'accrochage) sont déplacés afin qu'ils pénètrent le moins possible à l'intérieur de l'ouverture 42 et dégagent ainsi l'espace libre pour le passage d'une partie de l'article dans cette ouverture.In other words, the clamping members (hooking means) are moved so that they penetrate as little as possible inside the opening 42 and thus clear the free space for the passage of a portion of the article in this opening.

Dans le mode de réalisation qui vient d'être décrit, seul l'organe de serrage 2 est mobile sous l'action de la partie de commande de serrage 6.In the embodiment just described, only the clamping member 2 is movable under the action of the clamping control part 6.

A cet effet, l'utilisateur tourne la molette 21 selon son sens d'ouverture, ce mouvement entraînant en rotation la couronne 17 dans son sens bloquant. En même temps le contour intérieur 19b de la couronne 17, malgré la position non bloquante des couples de dents de scie du contour intérieur 19b de la couronne 17 et de la pièce 16 en forme de S disposée sur la came 9, entraîne tout de même cette dernière. Ce mouvement est possible car, en l'absence d'une force exercée sur l'organe de serrage 2, la flexibilité des branches de la pièce 16 en forme de S disposée sur la came 9 est suffisante pour permettre l'entrainement de la came 9 et donc la translation de l'organe de serrage 2.For this purpose, the user turns the knob 21 according to its opening direction, this movement causing the ring 17 to rotate in its blocking direction. At the same time the inner contour 19b of the ring 17, despite the non-locking position of the sawtooth pairs of the inner contour 19b of the ring 17 and the S-shaped piece 16 disposed on the cam 9, still causes the latter. This movement is possible because, in the absence of a force exerted on the clamping member 2, the flexibility of the branches of the S-shaped part 16 disposed on the cam 9 is sufficient to allow the drive of the cam 9 and therefore the translation of the clamping member 2.

Une fois l'article introduit dans l'ouverture 42, l'utilisateur tourne la molette 21 dans le sens de la fermeture de l'organe de serrage 2 ce qui va, dans un premier temps, entrainer la couronne 17 dont les dents du contour intérieur 19b vont bloquer les dents de la pièce 16 en forme de S disposée sur la came 9, puis entrainer la came 9 en rotation qui, à son tour, entraîne le support 2a de l'organe de serrage 2 en translation jusqu'à ce qu'il atteigne l'article 100 ( Figure 10 ). Once the article has been introduced into the opening 42, the user turns the knob 21 in the direction of the closure of the clamping member 2, which will initially cause the ring 17 to have the teeth of the outline 19b interior will block the teeth of the S-shaped piece 16 disposed on the cam 9, then drive the cam 9 in rotation which, in turn, drives the support 2a of the clamping member 2 in translation until it reaches Article 100 ( Figure 10 ).

Une fois l'organe de serrage mobile 2 en contact avec une face 100a de l'article 100 et, pour une valeur de couple prédéterminée lors de la conception du dispositif (couple de forces de serrage appliqué par l'utilisateur sur la molette), la couronne 17 va entrer en rotation dans son sens de rotation passant, par opposition au sens bloquant, rendant ainsi inutile toute tentative de serrage supplémentaire. L'article 100 est ainsi enserré par l'organe de serrage 2 et l'organe de serrage 3 en contact avec la face opposée 100b.Once the movable clamping member 2 comes into contact with a face 100a of the article 100 and, for a predetermined torque value during the design of the device (torque of clamping forces applied by the user on the wheel), the ring 17 will rotate in its direction of rotation as opposed to the blocking direction, thus making any further tightening attempts unnecessary. The article 100 is thus clamped by the clamping member 2 and the clamping member 3 in contact with the opposite face 100b.

On notera que la valeur prédéterminée du couple de forces est donnée, dans les exemples décrits, par la force qui doit être appliquée par l'utilisateur lors du serrage pour désengager les éléments en saillie de la couronne des éléments en saillie complémentaires du carter. Le diamètre de la molette d'actionnement centrée sur l'axe de rotation de la came facilite l'effort de serrage devant être appliqué par l'utilisateur pour exercer sur l'article un effort de serrage bien supérieur.Note that the predetermined value of the force torque is given in the examples described by the force to be applied by the user during tightening to disengage the elements protruding from the ring of complementary projecting elements of the housing. The diameter of the actuating wheel centered on the axis of rotation of the cam facilitates the clamping force to be applied by the user to exert on the article a much greater clamping force.

Lorsque la valeur prédéterminée du couple de forces est atteinte par l'utilisateur serrant la molette de la partie de commande, les organes de serrage (accrochage) exercent sur l'article un effort de serrage prédéterminé (pression de serrage P1) par la conception du dispositif et qui est adapté à l'article. Cet effort de serrage est déterminé par dimensionnement de l'ensemble des constituants du système interne de transmission de mouvement qui vient d'être décritWhen the predetermined value of the torque of forces is reached by the user pressing the knob of the control part, the clamping members (hooking) exert on the article a predetermined clamping force (clamping pressure P1) by the design of the device and that is suitable for the article. This clamping force is determined by sizing of all the constituents of the internal motion transmission system which has just been described.

L'article 100 se trouve ainsi verrouillé avec le dispositif antivol et donc sécurisé. Les moyens de repérage 23 (organe (s) actif(s) ou passif(s)) dissimulés dans la partie de commande 6 et/ou ceux disposés dans le logement 46f, 48f et/ou à un autre endroit du dispositif antivol 1 selon l'invention déclencheront une alarme lors du passage de l'article à proximité d'un portique de sécurité ou dialogueront avec un interrogateur de type RFID.Article 100 is thus locked with the antitheft device and therefore secure. The locating means 23 (active or passive member (s)) concealed in the control part 6 and / or those arranged in the housing 46f, 48f and / or at another location of the antitheft device 1 according to the invention will trigger an alarm when passing the article near a security portal or will dialogue with an RFID type interrogator.

A titre d'exemple, pour un rayon de molette égal à 1,27 cm et une force exercée par un utilisateur sur cette molette de 22,05N le couple de forces produit est de 28Ncm. L'effort de serrage résultant qui est appliqué par le dispositif à l'article 100 à protéger est d'environ 200N (pression de serrage P1).By way of example, for a wheel radius equal to 1.27 cm and a force exerted by a user on this wheel of 22.05N the couple of forces produced is 28Ncm. The resulting clamping force which is applied by the device to the article 100 to be protected is about 200N (clamping pressure P1).

Lorsque le dispositif antivol 1 est positionné sur l'article à protéger comme illustré sur la Figure 10 la pression de serrage exercée par les organes de serrage est prédéterminée pour ne pas détériorer l'article ni même laisser de trace après retrait du dispositif.When the antitheft device 1 is positioned on the article to be protected as illustrated on the Figure 10 the clamping pressure exerted by the clamping members is predetermined so as not to damage the article or even leave a trace after removal of the device.

Si un utilisateur mal intentionné souhaite retirer le dispositif 1 de l'article 100 afin de dérober ce dernier, il est incité à s'emparer du dispositif par la partie offrant le plus de surface aux doigts, à savoir celle qui fait saillie par rapport à la zone de serrage et donc par rapport à la molette 21.If a malicious user wishes to remove the device 1 of Article 100 in order to steal the device, it is encouraged to seize the device by the part offering the most surface to the fingers, namely that which protrudes from the clamping zone and therefore relative to the wheel 21.

Cette partie offrant une grande surface aux doigts d'un utilisateur mal intentionné est la partie de préhension 40 qui a été décrite ci-dessus.This part offering a large area to the fingers of a malicious user is the gripping portion 40 which has been described above.

Lorsque l'utilisateur exerce un effort de traction dans le sens indiqué par la flèche T sur la Figure 11 , en disposant ses doigts sur les faces latérales des deux demi-boîtiers 46 et 48, voire en introduisant un doigt dans la concavité formée par la portion 46e, 48e des deux demi-boîtiers (seule la portion 46e est représentée sur la Figure 11 ) et qui a la forme générale d'un pontet, le boîtier constitué des deux demi-boîtiers se déplace dans le sens indiqué par la flèche T.When the user exerts a tensile force in the direction indicated by the arrow T on the Figure 11 , by placing its fingers on the lateral faces of the two half-housings 46 and 48, or even by introducing a finger into the concavity formed by the portion 46e, 48e of the two half-housings (only the portion 46e is shown on FIG. Figure 11 ) and which has the general shape of a bridge, the housing consisting of two half-housings moves in the direction indicated by the arrow T.

Lors de ce déplacement la deuxième portion 74 de l'élément de liaison 70 glisse contre la surface formant rampe de la paroi interne 41 en regard, ce qui a pour effet d'abaisser cette deuxième portion et de déplacer, à la façon d'un levier, l'extrémité opposée en forme de pelle 72 qui porte l'élément de contact 86.During this movement, the second portion 74 of the connecting element 70 slides against the ramp surface of the inner wall 41 opposite, which has the effect of lowering the second portion and moving, in the manner of a lever, the opposite end in the form of a shovel 72 which carries the contact element 86.

En basculant ainsi, la première portion de l'élément de liaison 70 qui porte l'organe de serrage 3 est relevé, l'élément de contact 86 se déformant alors au contact de la face 100b de l'article, accentuant ainsi la pression de serrage sur ce dernier.By thus tilting, the first portion of the connecting element 70 which carries the clamping member 3 is raised, the contact element 86 then deforming in contact with the face 100b of the article, thus accentuating the pressure of tightening on the latter.

Tout comme l'organe de contact 2b, l'organe de contact 86 se déforme comme la pulpe du doigt d'un adulte et réalise ainsi un contact avec la face concernée de l'article sur une grande surface, sans abîmer celle-ci.Just like the contact member 2b, the contact member 86 is deformed like the finger pulp of an adult and thus makes contact with the relevant face of the article over a large area, without damaging it.

Lors du mouvement d'éloignement de la partie de préhension 40 depuis la position rapprochée de la zone de serrage, illustrée sur la Figure 10 , jusqu'à la position éloignée de celle-ci, illustrée sur la Figure 11 , les moyens élastiques 80 sont sollicités en compression entre la portion 46e, 48e du boîtier mobile et le fond du logement 54 du bloc fixe 44.During the movement away from the gripping portion 40 from the close position of the clamping zone, shown in FIG. Figure 10 , to the position distant from it, illustrated on the Figure 11 , the elastic means 80 are biased in compression between the portion 46e, 48e of the mobile housing and the bottom of the housing 54 of the fixed block 44.

Tant que l'effort de traction continue de s'appliquer sur la partie de préhension 40 et que celle-ci occupe la position de la Figure 11 , la pression de serrage augmentée (P2) continue de s'exercer sur l'article. Ainsi, c'est la force exercée par l'utilisateur mal intentionné qui augmente l'effort de serrage de l'article, rendant ainsi extrêmement difficile le retrait de celui-ci du dispositif antivol.As long as the tensile force continues to apply to the gripping portion 40 and that it occupies the position of the Figure 11 , the pressure of Increased tightening (P2) continues to be exerted on the article. Thus, it is the force exerted by the malicious user that increases the clamping force of the article, thus making it extremely difficult to remove it from the antitheft device.

Lorsque l'effort de traction diminue, voire est annulé, les moyens élastiques 80 exercent leur effort de rappel et repoussent la portion mobile 46e, 48e en direction de la zone de serrage afin de ramener le boîtier mobile dans la position rapprochée de la Figure 10 . When the tensile force decreases or is canceled, the elastic means 80 exert their return force and push the movable portion 46e, 48e towards the clamping zone in order to bring the mobile housing back into the close position of the Figure 10 .

Lors de ce déplacement inverse de la partie de préhension 40, l'extrémité en forme de bec 74 de l'élément de liaison 70 glisse à nouveau le long de la portion de paroi 41 et se relève pour revenir à la position initiale (non sollicitée) de la Figure 10 . During this reverse movement of the gripping portion 40, the spout-shaped end 74 of the connecting member 70 slides again along the wall portion 41 and rises to return to the initial (unsolicited) position. ) of the Figure 10 .

A titre d'exemple, l'effort de serrage augmenté qui est appliqué par le dispositif à l'article 100 est généralement compris entre 300 et 600N, sachant que l'effort additionnel est directement proportionnel à l'effort exercé sur la partie de préhension.For example, the increased clamping force that is applied by the device to article 100 is generally between 300 and 600N, knowing that the additional force is directly proportional to the force exerted on the gripping portion .

Ce mécanisme d'augmentation de pression est particulièrement utile pour renforcer l'accrochage du dispositif antivol sur l'article et donc renforcer la protection contre le vol.This pressure increase mechanism is particularly useful for reinforcing the attachment of the antitheft device on the article and thus enhance the protection against theft.

On notera que dans des variantes non représentées l'augmentation de serrage sur l'article peut résulter de la coopération de la partie de préhension avec un ou plusieurs autres éléments de liaison pouvant revêtir des formes différentes sans sortir pour autant du cadre de l'invention.It will be noted that in variants that are not shown, the tightening increase on the article can result from the cooperation of the gripping portion with one or more other connecting elements that can take on different shapes without departing from the scope of the invention. .

Comme illustré sur les Figures et décrit ci-dessus les deux organes de serrage du dispositif antivol se déplacent indépendamment l'un de l'autre sous l'action de mécanismes différents.As illustrated in the figures and described above, the two clamping members of the antitheft device move independently of one another under the action of different mechanisms.

En effet, le premier organe de serrage (organe de serrage 2) se déplace sous l'action d'un mécanisme de serrage mis en oeuvre lors de la fixation du dispositif à l'article à protéger, tandis que l'autre organe de serrage (organe de serrage 3) est actionné lors d'une tentative d'effraction et de séparation du dispositif de l'article.Indeed, the first clamping member (clamping member 2) moves under the action of a clamping mechanism implemented during attachment of the device to the article to be protected, while the other clamping member. (clamping member 3) is actuated during an attempted break-in and separation of the device of the article.

Une fois sécurisé, le desserrage du dispositif antivol 1 de l'article ne sera pas possible car, dans le sens de desserrage de la molette 21, la flexibilité des branches de la pièce 16 en forme de S disposée sur la came 9 est trop importante pour s'opposer au couple exercé lors du serrage. Les branches de la pièce 16 en forme de S disposée sur la came 9 vont donc fléchir principalement radialement, c'est-à-dire dans le plan du S, sans qu'aucun mouvement ne soit transmis aux moyens d'accrochage 4.Once secured, the loosening of the anti-theft device 1 of the article will not be possible because, in the loosening direction of the wheel 21, the flexibility of the branches of the S-shaped part 16 disposed on the cam 9 is too great to oppose the torque exerted during tightening. The branches of the S-shaped piece 16 disposed on the cam 9 will thus flex primarily radially, that is to say in the plane of the S, without any movement being transmitted to the attachment means 4.

L'unique façon de libérer l'article du dispositif antivol 1 selon l'invention consiste à embrayer la molette 21 avec la came 9 par l'intermédiaire du mécanisme d'embrayage 24.The only way to release the article of the antitheft device 1 according to the invention is to engage the wheel 21 with the cam 9 by means of the clutch mechanism 24.

Pour cela, l'utilisateur doit disposer un puissant aimant du type néodyme contre la face externe du carter 18 afin de sortir le doigt métallique 13 de son logement 12a et de l'attirer contre la face interne du carter 18 en s'opposant à la force de compression du ressort 14.For this, the user must have a powerful magnet of the neodymium type against the outer face of the housing 18 to release the metal finger 13 from its housing 12a and attract against the inner face of the housing 18 by opposing the compression force of the spring 14.

En même temps, l'utilisateur doit tourner la molette 21 dans le sens provoquant l'ouverture des organes ou mâchoires de serrage. Pour une certaine position de la molette 21, la portion rectangulaire 13b du doigt métallique 13 va pénétrer dans le logement 12b de forme rectangulaire complémentaire du carter 18. La rotation de la molette 21 entraînera alors directement la rotation de la came 9 par l'intermédiaire du doigt 13 dont la partie rectangulaire 13b sera disposée en partie dans le logement 12a de la came 9 et en partie dans le logement 12b du carter 18.At the same time, the user must turn the knob 21 in the direction causing the opening of the members or clamping jaws. For a certain position of the wheel 21, the rectangular portion 13b of the metal finger 13 will enter the housing 12b of complementary rectangular shape of the housing 18. The rotation of the wheel 21 will then directly cause the rotation of the cam 9 via finger 13 whose rectangular portion 13b will be partially disposed in the housing 12a of the cam 9 and partly in the housing 12b of the housing 18.

Une fois le dispositif antivol 1 séparé de l'article, l'utilisateur éloigne l'aimant et le ressort 14 se détend, entrainant le doigt 13 à l'intérieur de son logement 12a dans la came 9.Once the antitheft device 1 separated from the article, the user moves the magnet away and the spring 14 relaxes, causing the finger 13 inside its housing 12a in the cam 9.
