Abstract

The invention concerns a multipurpose seal with lock, comprising a mobile closure apparatus (1) consisting of a housing (2) containing a lock and a fastening element (3) designed to be locked in the housing. The lock comprises a cylinder (7) mobile in the housing between a locking position and an unlocking position. An electronic component (6) capable of being remotely queried and of storing data is maintained in a package (21) which passes through part of the housing (2) and part of the lock cylinder (7) when the latter is in locking position. Thus, any rotation of the cylinder from the locking position causes the component to break.

Description

Domaine de l'inventionField of the invention

La présente invention concerne un dispositif de scellé pour fermer et marquer des objets. Plus particulièrement, l'invention se rapporte aux dispositifs de scellé qui mettent en ouvre des moyens électroniques d'identification.The present invention relates to a sealing device for closing and marking objects. More particularly, the invention relates to sealing devices that implement electronic identification means.

Art antérieurPrior art

De nombreux types de scellés sont actuellement utilisés pour contrôler le cheminement ou le stockage de produits ou matériels qui présentent des besoins de sécurité ou de contrôle plus ou moins importants, comme, par exemple, des matières nucléaires, certains types de déchets ou bien de l'argent.Many types of seals are currently used to control the routing or storage of products or equipment that have more or less important security or control requirements, such as, for example, nuclear material, certain types of waste, or 'money.

Les technologies employées pour la réalisation des scellés sont très variées et dépendent principalement de l'usage et des degrés de sécurité demandés.The technologies used for the realization of seals are very varied and depend mainly on the use and the degrees of security required.

Ainsi, lorsqu'on désire s'assurer simplement de l'intégrité d'un objet, tel qu'un sac ou un coffre, la fonction du scellé est de garantir que l'objet n'a pas été ouvert sans autorisation. Dans ce cas, des dispositifs peu onéreux, comme de simples colliers de plastique ou de métal apposés sur les organes d'ouverture de l'objet, peuvent être utilisés. Une simple inspection visuelle de l'intégrité de la structure des colliers suffit alors pour constater que le scellé a été violé ou non.Thus, when it is desired to simply ensure the integrity of an object, such as a bag or a chest, the function of the seal is to ensure that the object has not been opened without authorization. In this case, inexpensive devices, such as simple plastic or metal collars affixed to the opening members of the object, can be used. A simple visual inspection of the integrity of the structure of the collars is then sufficient to find that the seal was violated or not.

Le document US2666318 divulgue un scellé et un procédé de fabrication d'un scellé selon les préambules des revendications 1 et 10. Il concerne un appareil de fermeture mobile sous forme d'un cadenas avec possibilité d'apposition d'un scellé. Afin d'éviter que des personnes non autorisées manipulent le cadenas, le scellé en forme de ruban passe au travers du cylindre du cadenas de telle sorte qu'il est impossible de faire tourner le cylindre sans que le scellé soit endommagé.The document US2666318 discloses a seal and a method of manufacturing a seal according to the preambles of claims 1 and 10. It relates to a mobile closure device in the form of a padlock with the possibility of affixing a seal. In order to prevent unauthorized persons from manipulating the lock, the tape-like seal passes through the padlock cylinder so that it is impossible to rotate the cylinder without the seal being damaged.

D'autre part, il existe de plus en plus de domaines dans lesquels les scellés doivent non seulement remplir leur fonction de base, qui est de pouvoir attester de l'inviolabilité de l'objet, mais aussi pouvoir fournir des informations durant leur utilisation. Ainsi, il existe actuellement des dispositifs qui comprennent des moyens mécaniques de scellement auxquels sont associés des moyens électroniques ou optiques qui permettent de mémoriser et transmettre des informations.On the other hand, there are more and more areas in which the seals must not only fulfill their basic function, which is to be able to attest to the inviolability of the object, but also to be able to provide information during their use. Thus, there are currently devices that include mechanical sealing means which are associated with electronic or optical means that can store and transmit information.

Cependant, les dispositifs de scellé actuels qui comprennent des moyens électroniques sont complexes et coûteux. Ils sont en général conçus pour un usage spécifique et ne peuvent pas être mis en oeuvre avec n'importe quel type d'objet. De plus, ils présentent une structure mécanique fragile qui les rend très sensibles aux manipulations et aux transports ce qui restreint encore leur utilisation.However, current sealing devices that include electronic means are complex and expensive. They are usually designed for a specific purpose and can not be implemented with any type of object. In addition, they have a fragile mechanical structure that makes them very sensitive to handling and transport which further restricts their use.

Le document EP0863489 présente un agencement avec un scellé à usage unique qui permet de déterminer si un boîtier a été ouvert. Le scellé comprend un composant électronique interrogeable à distance qui est fixé par une colle de manière à passer par deux parties de boîtier. Le composant électronique est détruit si on écarte les deux parties. Dans une autre variante, le composant électronique est situé dans un alésage au-dessus d'une vis reliant deux parties de boîtier. Le composant électronique et la tête de vis sont noyés par une colle. Le fait d'atteindre la tête de vis pour la dévisser endommagerait donc le composant électronique.The document EP0863489 has an arrangement with a single-use seal that determines whether a housing has been opened. The seal includes a remotely searchable electronic component that is secured by an adhesive to pass through two housing portions. The electronic component is destroyed if the two parts are separated. In another variant, the electronic component is located in a bore above a screw connecting two housing parts. The electronic component and the screw head are embedded in an adhesive. Reaching the screw head to unscrew it will therefore damage the electronic component.

Objet et description succincte de l'inventionObject and brief description of the invention

La présente invention vise à remédier aux inconvénients précités et à réaliser un dispositif de scellé à usage multiple de faible coût qui est mécaniquement robuste et qui contient des informations consultables de façon simple et rapide. Le dispositif doit aussi permettre un contrôle sûr et aisé de l'intégrité du scellé.The present invention aims at overcoming the aforementioned drawbacks and at achieving a low-cost, low-cost, multi-purpose seal device which is mechanically robust and which contains searchable information of easy and fast way. The device must also allow a safe and easy control of the integrity of the seal.

Ces buts sont atteints grâce à un scellé multi-usage à serrure, comprenant un appareil de fermeture mobile formé d'un boîtier renfermant une serrure et d'un élément d'attache destiné à être verrouillé dans le boîtier, la serrure comprenant un cylindre mobile dans le boîtier entre une position de verrouillage et une position de déverrouillage, caractérisé en ce qu'il comprend en outre un composant électronique interrogeable à distance qui comprend un moyen de mémorisation de données, le composant étant maintenu à l'aide d'un élément de maintien configuré comme pièce de forme dans un logement qui traverse une partie du boîtier et une partie du cylindre de serrure, lorsque ce dernier se trouve dans la position de verrouillage.These goals are achieved through a multi-purpose lock seal, comprising a movable closure apparatus formed of a lock housing and a fastener member for locking in the housing, the lock including a movable cylinder in the housing between a locking position and an unlocking position, characterized in that it further comprises a remotely interrogable electronic component which comprises a data storage means, the component being maintained by means of an element retainer configured as a shaped member in a housing that passes through a portion of the housing and a portion of the lock cylinder when the lock cylinder is in the locking position.

Ainsi, grâce au scellé selon l'invention, le composant électronique qui permet de mémoriser et de transmettre des informations devient également le témoin de l'intégrité du scellé. Le contrôle de l'intégrité du composant s'effectue par interrogation à distance de celui-ci, ce qui ne nécessite aucun démontage du scellé.Thus, thanks to the seal according to the invention, the electronic component that makes it possible to store and transmit information also becomes a witness to the integrity of the seal. The control of the integrity of the component is carried out by remote interrogation of the latter, which does not require any dismantling of the seal.

Selon l'invention, le boîtier comprend un évidement dont la forme correspond à celle de l'élément de maintien et dans lequel est fixé l'élément de maintien pour retenir le composant électronique dans le logement.According to the invention, the housing comprises a recess whose shape corresponds to that of the holding element and in which is fixed the holding element for retaining the electronic component in the housing.

Plus spécifiquement, l'élément de maintien comprend une cavité destinée à recevoir une partie du composant électronique, un ressort étant disposé entre le fond de la cavité et le composant électronique.More specifically, the holding member comprises a cavity for receiving a portion of the electronic component, a spring being disposed between the bottom of the cavity and the electronic component.

Afin de renforcer la fixation de l'élément de maintien dans le boîtier, le scellé peut comprendre en outre une goupille fixe qui bloque l'élément de maintien dans le boîtier.In order to enhance the attachment of the holding member in the housing, the seal may further include a fixed pin which locks the holding member in the housing.

Description détaillée des modes de réalisation de l'inventionDETAILED DESCRIPTION OF THE EMBODIMENTS OF THE INVENTION

Afin de ne pas compliquer inutilement la description, la présente invention sera essentiellement décrite en relation avec un appareil de fermeture mobile du type cadenas. Cependant, il apparaîtra clairement que la présente invention s'applique à tout type d'appareil de fermeture mobile qui comprend un boîtier renfermant un mécanisme de serrure actionnable par rotation d'un cylindre à l'aide d'une clé ou similaire.In order not to unnecessarily complicate the description, the present invention will be essentially described in connection with a mobile locking device of the padlock type. However, it will be apparent that the present invention applies to any type of closure apparatus mobile which comprises a housing enclosing a lock mechanism operable by rotation of a cylinder with a key or the like.

Les figures 1 à 5 montrent un mode de réalisation d'un scellé selon l'invention.The Figures 1 to 5 show an embodiment of a seal according to the invention.

Dans ce premier exemple de réalisation, le scellé est fabriqué à partir d'un cadenas 1 qui comprend principalement un boîtier 2 et un élément d'attache 3 tel qu'un arceau métallique. Le boîtier 2 renferme un mécanisme de serrure destiné à verrouiller au moins une des extrémités de l'élément d'attache 3. Tel que représenté en figure 1, l'élément d'attache 3 comprend une extrémité libre 33 munie d'une encoche 31 destinée à recevoir une panne (non représentée) du mécanisme de serrure pour verrouillage. L'autre extrémité 34 de l'élément 3 est maintenue dans le boîtier 2 de façon à permettre la rotation de l'élément 3 autour de cette extrémité quand le cadenas est déverrouillé. Comme pour l'extrémité 31, l'extrémité 34 peut aussi comprendre une encoche 32 destinée à recevoir une panne de verrouillage. De façon connue, les moyens de verrouillage du mécanisme de serrure du boîtier 2 sont actionnés dans le sens du déverrouillage par rotation d'un cylindre 7 autour de son axe à l'aide d'une clé 8 préalablement introduite dans une fente (71) du cylindre de serrure 7 (figure 5). Il est aussi connu que ce type de cadenas peut être verrouillé sans avoir à utiliser la clé, c'est-à-dire sans rotation du cylindre de serrure. En effet, lorsque aucune force n'est appliquée sur le cylindre par la clé 8, le cadenas est muni d'un mécanisme de rappel qui maintien le cylindre 7 dans une position de repos comme illustré en figures 1 et 2. De plus, la ou les pannes destinées à s'engager dans la ou les encoches de l'élément d'attache 3 sont aussi montées avec des ressorts de rappel qui les maintiennent en position de verrouillage de l'élément d'attache tant qu'on n'actionne pas le cylindre de serrure en rotation dans le sens S de déverrouillage (figure 5). Dans certains type de cadenas, le cylindre de serrure peut être actionné dans les deux sens pour provoquer le déverrouillage de l'élément d'attache. Pour fermer le cadenas, il suffit alors d'appuyer sur l'élément 3 afin de le déplacer en translation vers le boîtier 2 et faire ainsi descendre ses extrémités dans le boîtier et ceci sans mouvement du cylindre. Le mécanisme de serrure qui consiste à bloquer ou à libérer les extrémités de l'élément d'attache 3 est bien connu en soi et ne sera pas décrit plus en détail.In this first embodiment, the seal is made from a padlock 1 which mainly comprises a housing 2 and a fastening element 3 such as a metal bow. The housing 2 encloses a lock mechanism for locking at least one end of the fastening element 3. As shown in FIG. figure 1 , the fastening element 3 comprises a free end 33 provided with a notch 31 intended to receive a failure (not shown) of the lock mechanism for locking. The other end 34 of the element 3 is held in the housing 2 so as to allow the rotation of the element 3 around this end when the lock is unlocked. As for the end 31, the end 34 may also include a notch 32 for receiving a lockout failure. In known manner, the locking means of the lock mechanism of the housing 2 are actuated in the direction of unlocking by rotation of a cylinder 7 about its axis by means of a key 8 previously introduced into a slot (71). lock cylinder 7 ( figure 5 ). It is also known that this type of lock can be locked without having to use the key, that is to say without rotation of the lock cylinder. Indeed, when no force is applied to the cylinder by the key 8, the padlock is provided with a return mechanism which holds the cylinder 7 in a rest position as illustrated in FIG. figures 1 and 2 . In addition, the fault or failures intended to engage in the notch or notches of the fastening element 3 are also mounted with return springs which hold them in the locking position of the fastening element as long as the lock cylinder is not actuated in rotation in the unlocking direction S ( figure 5 ). In some type of padlock, the lock cylinder can be operated in either direction for cause unlocking of the fastener. To close the padlock, simply press the element 3 to move it in translation to the housing 2 and thus lower its ends in the housing and this without movement of the cylinder. The lock mechanism which consists in blocking or releasing the ends of the fastening element 3 is well known per se and will not be described in more detail.

Conformément à l'invention, le boîtier 2 est modifié pour pouvoir recevoir un composant électronique 6 qui peut être brisé mécaniquement. A cet effet, comme représenté en figure 3, un alésage 21 est usiné sur le côté du boîtier 2 afin de former un logement pour le composant 6. Dans ce mode réalisation, le composant 6 est maintenu dans l'alésage 21 par un élément 4 qui comprend une cavité 41 dans laquelle sont disposés un ressort 5 et une partie du composant 6. A cet effet, un évidemment 22, dont la forme correspond à celle de l'élément 4, est également usiné dans le boîtier 2 en amont de l'alésage 21. Ainsi, une fois l'élément 4 fixé dans le boîtier, le composant 6 est maintenu en butée contre le fond de l'alésage 21 par le ressort 5, lui-même en butée contre le fond de la cavité 41 de l'élément 4. L'élément 4 peut être fixé dans l'évidemment 22 du boîtier au moyen d'un simple collage. La fixation de l'élément 4 dans le boîtier peut être toutefois renforcée par une goupille 9 disposée dans un passage 23 percé dans le boîtier et dans une portion de l'élément 4 qui ne comprend pas la cavité 41 (figure 4).According to the invention, the housing 2 is modified to be able to receive an electronic component 6 which can be broken mechanically. For this purpose, as shown in figure 3 a bore 21 is machined on the side of the housing 2 to form a housing for the component 6. In this embodiment, the component 6 is held in the bore 21 by an element 4 which comprises a cavity 41 in which are arranged a spring 5 and a portion of the component 6. For this purpose, a recess 22, whose shape corresponds to that of the element 4, is also machined in the housing 2 upstream of the bore 21. Thus, once the 4 element fixed in the housing, the component 6 is held in abutment against the bottom of the bore 21 by the spring 5, itself abutted against the bottom of the cavity 41 of the element 4. The element 4 can be fixed in the recess 22 of the housing by means of a simple bonding. Fixing the element 4 in the housing may, however, be reinforced by a pin 9 disposed in a passage 23 pierced in the housing and in a portion of the element 4 which does not include the cavity 41 ( figure 4 ).

Comme illustré en figures 1, 2 et 5, l'alésage 21 s'étend à la fois dans une partie du boîtier 2 et dans une partie du cylindre 7 de la serrure du cadenas. La portion de l'alésage 21 située dans le boîtier et la portion de l'alésage 21 située dans le cylindre 7 sont alignées seulement lorsque ce dernier est en position de verrouillage. En d'autres termes, l'alésage 21 forme un logement commun dans le boîtier et le cylindre pour le composant 6 seulement lorsque le cylindre est en position de verrouillage, c'est à dire sa position de repos.As illustrated in figures 1 , 2 and 5 , the bore 21 extends both in a portion of the housing 2 and in a portion of the cylinder 7 of the padlock lock. The portion of the bore 21 located in the housing and the portion of the bore 21 in the cylinder 7 are aligned only when the latter is in the locking position. In other words, the bore 21 forms a common housing in the housing and the cylinder for the component 6 only when the cylinder is in the locking position, that is to say its rest position.

Ce qui est important, c'est que la profondeur de l'alésage 21 dans le cylindre 7 ne dépasse pas la longueur du composant 6 pour garantir que ce dernier, une fois maintenu en butée au fond de l'alésage 21, sera présent à la fois dans le cylindre 7 et dans le boîtier 2 (figure 5). A titre d'exemple, dans le mode de réalisation décrit ici, la profondeur de l'alésage 21 dans le cylindre 7 est d'environ 2 mm. Ainsi, le composant 6 se trouve en opposition à tout mouvement de rotation du cylindre 7 par rapport au boîtier 2 qui forme un stator. Du fait de sa fragilité mécanique, toute tentative de déverrouillage du cadenas par actionnement du cylindre entraînera la rupture du composant. Par conséquent, l'intégrité du scellé selon l'invention est assurée par l'intégrité mécanique et, par conséquent, électronique du composant.What is important is that the depth of the bore 21 in the cylinder 7 does not exceed the length of the component 6 to ensure that the latter, once held in abutment at the bottom of the bore 21, will be present at both in the cylinder 7 and in the housing 2 ( figure 5 ). By way of example, in the embodiment described here, the depth of the bore 21 in the cylinder 7 is about 2 mm. Thus, the component 6 is in opposition to any rotational movement of the cylinder 7 relative to the housing 2 which forms a stator. Because of its mechanical fragility, any attempt to unlock the padlock by actuating the cylinder will cause the breakage of the component. Therefore, the integrity of the seal according to the invention is provided by the mechanical integrity and, therefore, the electronic component.

Un composant électronique qui peut être utilisé dans le scellé selon l'invention est un composant électronique passif interrogeable à distance comme un transpondeur du type de ceux injectés ou implantés dans les animaux domestiques pour leur identification. Un transpondeur est un dispositif qui transmet l'information qu'il a en mémoire lorsqu'il est activé par un émetteur-récepteur. Eventuellement, il peut stocker de nouvelles informations.An electronic component that can be used in the seal according to the invention is a passive electronic component remotely searchable as a transponder of the type of those injected or implanted in domestic animals for their identification. A transponder is a device that transmits the information it has in memory when activated by a transceiver. Possibly, it can store new information.

Plus précisément, un tel composant électronique comporte un circuit électronique qui comprend des moyens formant antenne, comme une bobine enroulée autour d'un noyau de ferrite, et une partie électronique essentiellement composée de moyens de mémorisation. Les moyens formant antenne servent non seulement à la transmission des données mais aussi à recevoir un champ d'activation pour l'alimentation en énergie électrique du circuit électronique.More specifically, such an electronic component comprises an electronic circuit which comprises antenna means, such as a coil wound around a ferrite core, and an electronic part consisting essentially of storage means. The antenna means serve not only for the transmission of data but also to receive an activation field for the supply of electrical energy to the electronic circuit.

Un exemple de transpondeur passif pouvant être utilisé dans la présente invention est un modèle (B T-IS 6110 avec un code d'identification industriel et non animal en accord avec la norme ISO 11784) de la société DATAMARS SA. Ce modèle de transpondeur comprend un circuit électronique miniature qui est enveloppé dans un cylindre de verre de très petites dimensions, à savoir 14 mm de longueur pour 2 mm de diamètre. Le circuit électronique comporte une mémoire d'une capacité de 128 bits qui peut être programmable ou multipages (transpondeur de type "Full Duplex" (FDX)).An example of a passive transponder that can be used in the present invention is a model (B T-IS 6110 with an industrial and non-animal identification code in accordance with the ISO 11784 standard) of DATAMARS SA. This model of transponder comprises a miniature electronic circuit which is wrapped in a glass cylinder of very small dimensions, namely 14 mm in length and 2 mm in diameter. The electronic circuit comprises a memory of a capacity of 128 bits which can be programmable or multi-page (transponder type "Full Duplex" (FDX)).

La lecture des données mémorisées dans le transpondeur, telles que l'identité du scellé ou des informations sur le contenu scellé, peut être effectuée par exemple à l'aide d'un lecteur portable 50 représenté en figure 6. Un tel lecteur peut notamment comporter un écran d'affichage 51, un clavier 52 et/ou des moyens de mémorisation des données interrogées. Le lecteur active le transpondeur par radiofréquence (RF), par exemple à une fréquence de 134.2 kHz. Cette onde charge une capacité présente dans le circuit du transpondeur. Lorsque cette dernière se décharge, elle renvoie au lecteur un code ou une information, inscrite dans la mémoire du transpondeur.The reading of the data stored in the transponder, such as the identity of the seal or information on the sealed content, can be performed for example with the aid of a portable reader 50 represented in FIG. figure 6 . Such a reader may include in particular a display screen 51, a keyboard 52 and / or storage means interrogated data. The reader activates the radio frequency (RF) transponder, for example at a frequency of 134.2 kHz. This wave charges a capacitance present in the transponder circuit. When the latter discharges, it sends back to the reader a code or information, stored in the transponder memory.

Le code et/ou les informations de chaque transpondeur interrogé sont ainsi envoyés vers le lecteur 50 et affichés sur son écran 51 et/ou stockés dans sa mémoire, ou transférés, via une liaison série, vers un ordinateur. Un logiciel peut permettre d'établir la corrélation entre le numéro d'identification du scellé (le code du transpondeur) et des données diverses telles que par exemple le lieu, et/ou le nom de l'inspecteur ayant installé le scellé, et/ou la date de pose du scellé. Le système ainsi constitué permet la lecture des données du scellé à une distance pouvant aller jusqu'à 30 cm environ, ce qui est suffisant pour la plupart des utilisations.The code and / or information of each interrogated transponder are thus sent to the reader 50 and displayed on its screen 51 and / or stored in its memory, or transferred, via a serial link, to a computer. Software may make it possible to correlate the seal identification number (the transponder code) with various data such as, for example, the location, and / or the name of the inspector who installed the seal, and / or the date of sealing. The system thus constituted makes it possible to read the data of the seal at a distance of up to about 30 cm, which is sufficient for most uses.

Le type de transpondeur décrit ci-dessus est particulièrement adapté pour la présente invention. En effet, de tels composants présentent un encombrement très réduit ce qui permet de les loger facilement dans de petits appareils de fermeture mobiles tels que des cadenas. De plus, l'enveloppe de protection du circuit étant en verre, elle peut être brisée facilement et permettre ainsi la destruction du circuit électronique avec peu de résistance, en particulier vis-à-vis de l'effort de cisaillement appliqué au composant lors de la rotation du cylindre de serrure.The type of transponder described above is particularly suitable for the present invention. Indeed, such components have a very small footprint which allows them to be easily housed in small mobile closure devices such as padlocks. In addition, since the protective envelope of the circuit is made of glass, it can be broken easily and thus allow the destruction of the electronic circuit with little resistance, especially vis-à-vis the shear force applied to the component during the rotation of the lock cylinder.

Ainsi, grâce à cette conception de scellé propre à l'invention, l'intégrité de ce dernier peut être contrôlée de manière très simple et rapide bien qu'elle ne soit pas apparente. En effet, toute tentative de violation du scellé par ouverture du cadenas est sanctionnée par la destruction mécanique du composant. Ainsi, l'intégrité du composant, et par conséquent celle du scellé, sera contrôlée à l'aide d'un lecteur. Si le composant ne répond pas à une interrogation du lecteur cela signifie que le circuit électronique de celui-là a subi des dommages et que l'intégrité du scellé est contestable.Thus, thanks to this seal design of the invention, the integrity of the latter can be controlled very simply and quickly although it is not apparent. Indeed, any attempt to breach the seal by opening the lock is sanctioned by the mechanical destruction of the component. Thus, the integrity of the component, and therefore that of the seal, will be controlled using a reader. If the component does not respond to an interrogation of the reader it means that the electronic circuit of that one has been damaged and that the integrity of the seal is questionable.

Selon le principe du scellé, celui-ci ne peut être apposé qu'une fois sans atteinte à son intégrité. Le scellé selon l'invention répond aux mêmes exigences. Le scellé est fourni dans la configuration représentée en figure 1, c'est à dire avec l'élément d'attache 3 déverrouillé pour permettre de passer ce dernier par exemple dans des pitons ou anneaux clos d'un sac ou autre que l'on désire fermer de façon inviolable. Une fois le cadenas verrouillé, le scellé selon l'invention se trouve dans la configuration représentée en figure 2 où l'élément d'attache est verrouillé dans le boîtier 2. Cette configuration correspond au scellé apposé et toute tentative d'ouverture du cadenas entraînera la destruction du composant et par conséquent celle du scellé.According to the principle of the seal, it can be affixed once without breaching its integrity. The seal according to the invention meets the same requirements. The seal is provided in the configuration shown in figure 1 , ie with the fastening element 3 unlocked to allow the latter to pass for example in studs or closed rings of a bag or other that it is desired to close inviolably. Once the lock is locked, the seal according to the invention is in the configuration shown in FIG. figure 2 where the fastening element is locked in the housing 2. This configuration corresponds to the seal affixed and any attempt to open the lock will cause the destruction of the component and therefore that of the seal.

Afin d'empêcher toute fermeture intempestive du cadenas et donc la perte du scellé lors de son transport ou de sa manipulation avant son utilisation, il peut être prévu des moyens amovibles sur l'élément d'attache, le boîtier ou les deux. Un exemple d'un tel moyen est illustré en figure 7. Sur cette figure, l'extrémité libre 33 de l'élément d'attache 3 est couverte d'un capuchon 35 dont la largeur L2 est supérieure à la largeur L1 de l'orifice 24 du boîtier 2 dans lequel se loge l'extrémité 33 pour être verrouillée. Ainsi, tant que l'extrémité de l'élément d'attache sera couverte du capuchon, cette dernière ne pourra pas être introduite dans l'orifice 24. Alternativement, la fermeture intempestive du cadenas peut être empêchée par des moyens amovibles présents sur le boîtier 2 tel qu'un adhésif ou un opercule qui obstrue l'orifice 24. Le moyen amovible peut également consister en une entretoise, démontable ou cassable, disposée entre le boîtier et la partie supérieure de l'élément d'attache 3 pour maintenir ce dernier à une distance déterminée qui empêche l'extrémité libre de pénétrer dans le boîtier.In order to prevent any inadvertent closure of the padlock and thus the loss of the seal during its transport or handling before use, it may be provided removable means on the fastener, the housing or both. An example of such a means is illustrated in figure 7 . In this figure, the free end 33 of the fastening element 3 is covered with a cap 35 whose width L 2 is greater than the width L 1 of the orifice 24 of the housing 2 in which the end 33 is housed to be locked. Thus, as long as the end of the fastener element is covered with the cap, it can not be inserted into the orifice 24. Alternatively, the inadvertent closure of the padlock can be prevented by removable means on the housing 2, such as an adhesive or a cover which obstructs the orifice 24. The removable means may also consist of a spacer, removable or breakable, disposed between the housing and the upper part of the attachment element 3 to hold the latter at a determined distance that prevents the free end from entering the housing.

La figure 8 montre un autre mode de réalisation d'un scellé multi-usage selon l'invention. Dans ce mode de réalisation, un scellé est fabriqué à partir d'un appareil de fermeture mobile 100 du type antivol pour cycle. L'élément d'attache 103 est constitué par un câble d'acier ou une chaîne, éventuellement recouvert d'une gaine plastique, dont une extrémité 134 est fixée à un boîtier 102 renfermant un mécanisme de serrure. L'autre extrémité 133 de l'élément d'attache 103 est laissée libre lorsqu'elle n'est pas verrouillée dans le boîtier 102. De la même façon que pour le mode de réalisation précédent, le boîtier 102 est modifié pour recevoir un composant 106 du même type que celui précédemment décrit, ce dernier étant maintenu entre une partie du boîtier 102 et du cylindre de serrure 107 au moyen d'un élément 104 et d'un ressort 105. Toute rotation du cylindre 107 à l'aide d'une clé 108 entraînera la destruction du composant 106.The figure 8 shows another embodiment of a multi-purpose seal according to the invention. In this embodiment, a seal is made from a mobile closure apparatus 100 of the antitheft type for a cycle. The fastening element 103 is constituted by a steel cable or a chain, possibly covered with a plastic sheath, one end 134 of which is fixed to a housing 102 enclosing a lock mechanism. The other end 133 of the fastening element 103 is left free when it is not locked in the housing 102. In the same way as for the previous embodiment, the housing 102 is modified to receive a component 106 of the same type as that previously described, the latter being held between a portion of the housing 102 and the lock cylinder 107 by means of an element 104 and a spring 105. Any rotation of the cylinder 107 with the aid of a key 108 will destroy component 106.

Le mode de réalisation présenté en figure 8 fonctionne de façon similaire à celui décrit en relation avec les figures 1 à 5 et peut comprendre, de façon évidente, toutes les caractéristiques particulières décrites précédemment. Par souci de simplification, il ne sera donc pas décrit plus en détail.The embodiment presented in figure 8 similar to the one described in relation to the Figures 1 to 5 and may include, obviously, all the particular features previously described. For the sake of simplicity, it will not be described in more detail.

Le scellé selon l'invention présente les avantages suivants.The seal according to the invention has the following advantages.

Les informations, telles qu'un code d'identification, peuvent être lues sans démontage ou altération du scellé lorsque celui-ci est apposé. Grâce à l'enveloppe de verre qui protège le circuit électronique, le transpondeur est étanche et résistant aux attaques chimiques. Par conséquent, les informations peuvent être lues même dans des conditions de stockage particulières. Ainsi, par exemple, les données mémorisées dans le scellé peuvent être lues lorsque celui-ci est immergé.The information, such as an identification code, can be read without dismantling or tampering with the seal when it is affixed. Thanks to the glass envelope that protects the electronic circuit, the transponder is waterproof and resistant to chemical attack. Therefore, the information can be read even under particular storage conditions. Thus, for example, the data stored in the seal can be read when it is immersed.

L'utilisation d'un lecteur pour l'identification et l'interrogation du scellé facilite le travail de contrôle. Il suffit de transporter le lecteur sur chacun des sites à contrôler. Il n'est pas nécessaire d'emmener chacun des scellés vers un laboratoire ou un centre d'analyse pour disposer de moyens d'ouverture et de lecture particuliers.The use of a reader for identification and interrogation of the seal facilitates the control work. Just carry the reader on each site to control. It is not necessary to take each seal to a laboratory or an analysis center to have special means of opening and reading.

Les données mémorisées dans le scellé peuvent être facilement stockées, grâce à une simple liaison informatique série. On peut alors traiter rapidement les données extraites, ce qui accélère et abaisse le coût de l'identification.The data stored in the seal can be easily stored, thanks to a simple serial computer link. The extracted data can then be processed quickly, which speeds up and lowers the cost of identification.

Il est possible d'utiliser des transpondeurs multipages afin de stocker des informations diverses, comme des informations sur la nature, la provenance, les étapes de cheminement ou bien le lieu de départ du matériel ou produit scellé, ce qui augmente encore les possibilités du scellé. Lors d'un acheminement en plusieurs étapes par exemple, les informations pourront être utiles pour déterminer le lieu ou la date d'un éventuel viol du scellé.Multi-page transponders can be used to store various types of information, such as information about the nature, provenance, routing steps, or location of the material or sealed product, further increasing the possibilities of the seal. . For example, when routing in several steps, the information may be useful in determining the location or date of any possible breach of the seal.

Lorsque le circuit du transpondeur comprend des moyens programmables ou encryptables, il est possible de coder ou crypter les données mémorisées dans le scellé, d'où un niveau de sécurité accru.When the transponder circuit comprises programmable or encryptable means, it is possible to encode or encrypt the data stored in the seal, resulting in an increased level of security.

Le scellé présente un faible coût de fabrication (environ 10 Euros suivant la quantité produit pour un scellé fabriqué à partir d'un cadenas).The seal has a low manufacturing cost (about 10 Euros depending on the quantity produced for a seal made from a padlock).

La vérification de l'intégrité du scellé est réalisée de façon simple et rapide: si le lecteur ne peut lire les informations mémorisées c'est que le scellé à été violé.Verification of the integrity of the seal is carried out simply and quickly: if the reader can not read the stored information is that the seal has been violated.

Le scellé présente une robustesse mécanique importante qui permet de l'utiliser comme appareil de fermeture fiable. De plus, une fois posé, le scellé ne nécessite aucune précaution particulière pour protéger son intégrité. En effet, le témoin d'intégrité, à savoir le composant, est protégé à l'intérieur de l'appareil de fermeture contre toute destruction qui pourrait intervenir lors de la manipulation de l'objet scellé.The seal has a high mechanical strength that allows it to be used as a reliable locking device. In addition, once installed, the seal does not require any special precautions to protect its integrity. Indeed, the integrity indicator, namely the component, is protected inside the closure device against any destruction that may occur during handling of the sealed object.

Il est également possible d'avoir une clé unique pour une pluralité d'appareils de fermeture utilisés comme scellés selon l'invention. Ce qui simplifie encore leur utilisation.It is also possible to have a single key for a plurality of closures used as seals according to the invention. Which further simplifies their use.
