Description

DESCRIPTION DESCRIPTION

TITRE DE L’INVENTION : DISPOSITIF AMOVIBLE DE SERRURE À CODE POURTITLE OF THE INVENTION: REMOVABLE CODE LOCK DEVICE FOR

BARILLET DE SERRURE DE PORTE DOOR LOCK CYLINDER

Domaine technique de l’invention Technical field of the invention

La présente invention vise un dispositif amovible de serrure à code pour barillet de serrure de porte. Elle s’applique, en particulier, à l’autorisation ponctuelle d’accès à une serrure et, au- delà, à un local. L’invention s’applique, par exemple, à la location de courte durée de biens immobiliers. The present invention relates to a removable code lock device for a door lock cylinder. It applies, in particular, to the temporary authorization of access to a lock and, beyond that, to a room. The invention applies, for example, to the short-term rental of real estate.

État de la technique State of the art

Les serrures à code existantes sont contraignantes au niveau de l’installation et de l’utilisation. Pour équiper une porte d’une serrure à code à la place d’une serrure à clé, il est nécessaire de faire appel à un serrurier, ou de savoir bricoler et être équipé d’outils pour son installation. Une fois que la serrure à code est installée, il n’est pas possible de revenir à l’usage du barillet à clé traditionnelle sans de nouveau faire un démontage complet. Existing code locks are restrictive in terms of installation and use. To equip a door with a code lock instead of a key lock, it is necessary to call a locksmith, or to know how to tinker and be equipped with tools for its installation. Once the code lock is installed, it is not possible to return to the use of the traditional key cylinder without again carrying out a complete disassembly.

On connaît le document EP 3 498 945 qui décrit un dispositif amovible de serrure à code à insérer dans un barillet de serrure à clé mécanique comportant un rotor muni d’une fente et de goupilles internes dans le plan de cette fente. Document EP 3 498 945 is known, which describes a removable code lock device to be inserted into a mechanical key lock cylinder comprising a rotor provided with a slot and internal pins in the plane of this slot.

Présentation de l’invention Presentation of the invention

La présente invention vise à remédier à tout ou partie de ces inconvénients. The present invention aims to remedy all or part of these drawbacks.

A cet effet, la présente invention vise un dispositif amovible de serrure à code à insérer dans un barillet de serrure à clé mécanique comportant : To this end, the present invention relates to a removable code lock device to be inserted into a mechanical key lock cylinder comprising:

- un rotor muni d’une fente parallèle à un plan et de goupilles internes dans un autre plan que le plan de la fente, et - a rotor provided with a slot parallel to a plane and with internal pins in a plane other than the plane of the slot, and

- un stator muni de contre-goupilles externes au rotor, les dimensions des contre-goupilles leur permettant d’entrer dans la fente du rotor, le dispositif comportant un boîtier solidaire d’une première partie de clé munie de reliefs correspondant aux goupilles du rotor, le boîtier comportant : - a stator provided with counter-pins external to the rotor, the dimensions of the counter-pins allowing them to enter the slot of the rotor, the device comprising a casing integral with a first key part provided with reliefs corresponding to the pins of the rotor , the housing comprising:

- une deuxième partie de clé mobile par rapport au boîtier, - a second mobile key part relative to the case,

- un moyen de réception de codes candidats et - a means for receiving candidate codes and

- un moyen de mise en mouvement linéaire de la deuxième partie de clé dans la fente du rotor après réception d’un code candidat correspondant à un code prédéterminé. - a means for setting the second part of the key in linear motion in the slot of the rotor after receiving a candidate code corresponding to a predetermined code.

Grâce à ces dispositions, l’accès à une serrure peut être condamné en positionnant le dispositif en regard du barillet, en introduisant la première partie de clé dans la fente du rotor barillet, ce qui a pour effet de libérer la rotation du barillet, puis en lui faisant faire une rotation dans le sens inverse du sens de rotation provoquant l’ouverture de la serrure. La deuxième partie de clé n’étant alors pas insérée jusqu’au fond du barillet, des contre-goupilles du stator entrent dans la fente lorsque la fente du rotor est présentée devant ces contre-goupilles. Cette particularité permet, d’une part le blocage de la rotation du rotor par rapport au barillet, et d’autre part, le blocage de la première partie de clé dans le barillet afin que le dispositif ne puisse être retiré du barillet. Thanks to these arrangements, access to a lock can be blocked by positioning the device opposite the barrel, by introducing the first part of the key into the slot of the barrel rotor, which has the effect of releasing the rotation of the barrel, then by causing it to rotate in the opposite direction to the direction of rotation causing the lock to open. Since the second part of the key is then not inserted to the bottom of the barrel, counter-pins of the stator enter in the slot when the rotor slot is presented in front of these cross pins. This feature allows, on the one hand the blocking of the rotation of the rotor relative to the barrel, and on the other hand, the blocking of the first part of the key in the barrel so that the device cannot be removed from the barrel.

Pour déverrouiller la serrure, un utilisateur doit fournir un code correspondant au code prédéterminé. Ensuite il doit provoquer le mouvement d’enfoncement de la deuxième partie de clé dans la fente du rotor, ce qui a pour effet de repousser les contre-goupilles du stator en dehors de cette fente et de permettre la rotation du rotor pour ouvrir la porte. To unlock the lock, a user must provide a code corresponding to the predetermined code. Then he must cause the movement of the second part of the key to push into the slot of the rotor, which has the effect of pushing the counter-pins of the stator out of this slot and allowing the rotation of the rotor to open the door. .

Dans des modes de réalisation, le moyen de mise en mouvement linéaire de la deuxième partie de clé dans la fente du rotor comporte un bouton-poussoir solidaire de la deuxième partie de clé. In some embodiments, the means for setting the second key part in linear motion in the slot of the rotor comprises a push-button secured to the second key part.

Ainsi, après avoir saisi le code correct, l’utilisateur appui sur le bouton-poussoir pour faire pénétrer la deuxième partie de clé dans la fente et en chasser les contre-goupilles du stator. Dans des modes de réalisation, le bouton-poussoir est muni d’un ressort de rappel dont la force fait ressortir au moins partiellement la deuxième partie de clé de la fente. Thus, after having entered the correct code, the user presses the push-button to insert the second part of the key into the slot and push out the counter-pins of the stator. In some embodiments, the push button is provided with a return spring, the force of which at least partially brings out the second part of the key from the slot.

Ainsi, une fois la porte ouverte, lorsque l’utilisateur relâche le bouton-poussoir, la deuxième partie de clé libère une place dans la fente du rotor pour que des contre-goupilles du stator puissent y pénétrer. Ainsi, l’utilisateur s’il souhaite laisser le dispositif sur la porte à la suite de l’ouverture de celle-ci, il ne lui reste plus qu’à tourner le dispositif jusqu’à trouver le point de blocage, c’est-à-dire tourner jusqu’à ce que la fente du rotor se présente en face des contre- goupilles du stator et, dans le cas d’une interface mécanique de saisie du code, à brouiller le code, c’est-à-dire ne pas le laisser apparent. Thus, once the door is open, when the user releases the push button, the second part of the key frees up a place in the slot of the rotor so that the counter-pins of the stator can enter it. Thus, the user, if he wishes to leave the device on the door after opening the latter, all he has to do is turn the device until he finds the blocking point, that is i.e. to rotate until the slot in the rotor is opposite the counter pins of the stator and, in the case of a mechanical code entry interface, to scramble the code, i.e. say don't leave it apparent.

L’invention permet ainsi d’appliquer une serrure à code à un barillet serrure de la porte d’un logement. La clé de la porte n’a pas besoin d’être mise à disposition d’un tiers. Le dispositif de serrure à code étant rajouté sur le barillet effectue une authentification à code prédéterminé pour autoriser l’utilisation de la porte. Ainsi, le tiers est authentifié par ce qu’il sait, c’est-à-dire le code secret prédéterminé. The invention thus makes it possible to apply a code lock to a lock cylinder of the door of a dwelling. The door key does not need to be made available to a third party. The code lock device being added to the cylinder carries out an authentication with a predetermined code to authorize the use of the door. Thus, the third party is authenticated by what he knows, that is to say the predetermined secret code.

Le dispositif objet de l’invention s’insère dans le barillet de la serrure et bloque celui-ci. La seule manière d’ouvrir la serrure et/ou de retirer le dispositif du barillet est de connaitre le code secret prédéterminé. L’interface de fourniture peut être aussi bien mécanique qu’électronique. Si le dispositif est forcé et cassé, la première partie de clé reste coincée dans le barillet de serrure, ce qui empêche l’insertion ultérieure d’une clé. The device that is the subject of the invention is inserted into the cylinder of the lock and blocks it. The only way to open the lock and/or remove the device from the cylinder is to know the predetermined secret code. The supply interface can be either mechanical or electronic. If the device is forced open and broken, the first part of the key remains stuck in the key cylinder, preventing subsequent insertion of a key.

Pour ouvrir la serrure et/ou enlever le dispositif de serrure à code, l’utilisateur doit connaitre le code secret qui lui est communiqué par le propriétaire ou locataire du logement. To open the lock and/or remove the code lock device, the user must know the secret code communicated to him by the owner or tenant of the accommodation.

La serrure offre alors la souplesse d’une utilisation mixte : ouverture avec une clé traditionnelle ou, après positionnement d’un dispositif selon l’invention, avec un code secret. The lock then offers the flexibility of mixed use: opening with a traditional key or, after positioning a device according to the invention, with a secret code.

Dans des modes de réalisation, le moyen de réception de codes candidats comporte une serrure à combinaison mécanique. Par exemple, cette serrure à combinaison mécanique est à rouleaux, à mouvements directionnels. Grâce à ces dispositions, le dispositif n’a pas besoin de source d’énergie et l’utilisateur n’a pas besoin d’un autre appareil pour utiliser le dispositif. In embodiments, the candidate code receiving means comprises a mechanical combination lock. For example, this mechanical combination lock is roller-operated, with directional movements. Thanks to these provisions, the device does not need a power source and the user does not need another device to use the device.

Dans des modes de réalisation, le rotor du barillet comporte un trou en son fond et la seconde partie de clé comporte une tige en son extrémité. In some embodiments, the rotor of the barrel has a hole in its bottom and the second key part has a rod at its end.

Lorsque l’utilisateur enfonce le bouton-poussoir, cette tige passe par le trou du rotor, et vient se coincer dans la partie opposée du rotor, ce qui a pour résultat de bloquer la rotation du rotor. When the user presses the push button, this rod passes through the hole in the rotor, and gets stuck in the opposite part of the rotor, which results in the rotation of the rotor being blocked.

Dans des modes de réalisation, le dispositif comporte une réserve d’énergie électrique, une interface électronique de réception d’un code candidat et une unité centrale de reconnaissance du code prédéterminé. In some embodiments, the device comprises an electrical energy reserve, an electronic interface for receiving a candidate code and a central unit for recognizing the predetermined code.

Dans des modes de réalisation, l’interface de réception comporte un moyen de communication avec un terminal mobile communiquant. In embodiments, the receiving interface comprises a means of communication with a communicating mobile terminal.

Grâce à ces dispositions, le code peut être conservé en mémoire du terminal portable communicant ou être saisi par l’intermédiaire d’une interface utilisateur. Thanks to these provisions, the code can be stored in the memory of the communicating portable terminal or be entered via a user interface.

Dans le premier cas, l’utilisateur peut ne pas connaître le code qui lui a été transmis de manière chiffrée par un serveur de réservation d’un local accessible par l’intermédiaire de la serrure codée, ce qui augmente la sécurité du code secret contre les divulgations. In the first case, the user may not know the code transmitted to him in encrypted form by a reservation server of a room accessible via the coded lock, which increases the security of the secret code against disclosures.

Dans des modes de réalisation, le dispositif comporte une bague rotative et un mécanisme de transformation d’un mouvement de rotation de la bague en un mouvement de translation de la deuxième partie de clé. In some embodiments, the device comprises a rotating ring and a mechanism for transforming a rotational movement of the ring into a translational movement of the second key part.

Dans des modes de réalisation, le mécanisme de transformation du mouvement comporte un ressort dont la force fait sortir la deuxième partie de clé de la fente du rotor lorsque l’utilisateur relâche la bague. In embodiments, the movement transformation mechanism comprises a spring whose force forces the second key part out of the rotor slot when the user releases the ring.

Dans des modes de réalisation, le dispositif comporte au moins un moteur de mise en mouvement de la deuxième partie de la clé. In some embodiments, the device comprises at least one motor for moving the second part of the key.

Grâce à ces dispositions, l’utilisateur n’a pas à exercer de force importante sur le dispositif pour l’actionner. Thanks to these provisions, the user does not have to exert significant force on the device to actuate it.

Description des modes de réalisation Description of embodiments

La présente description est donnée à titre non limitatif, chaque caractéristique d’un mode de réalisation pouvant être combinée à toute autre caractéristique de tout autre mode de réalisation de manière avantageuse. This description is given on a non-limiting basis, each characteristic of an embodiment being able to be combined with any other characteristic of any other embodiment in an advantageous manner.

On note, dès à présent, que les figures 1 à 29 sont, chacune, à l’échelle et que les échelles des différentes figures peuvent être différentes. We note, from now on, that figures 1 to 29 are each to scale and that the scales of the different figures may be different.

Dans toute la description, on appelle « interne » ou « central » ce qui proche de ou orienté vers un axe de rotation du barillet ou du dispositif et, « externe », ce qui est éloigné ou orienté à l’opposé de cet axe. La longueur du dispositif est définie selon cet axe. On appelle « avant », ce qui est orienté dans le sens de l’insertion d’une clé dans le barillet, c’est-à-dire, pour le dispositif, du côté de la porte, et « arrière » ce qui dans le sens opposé. On appelle face, la partie de la serrure visible depuis l’extérieur de la porte et « de face », les figures faites dans le sens du regard vers cette face. Les sens de rotation sont définis sur les vues de face.Throughout the description, the term “internal” or “central” is used to refer to that which is close to or oriented towards an axis of rotation of the barrel or of the device and, “external”, which is distant from or oriented opposite to this axis. The length of the device is defined along this axis. We call "front" what is oriented in the direction of insertion of a key in the barrel, that is to say, for the device, on the side of the door, and "rear" what in the opposite direction. We call face, the part of the lock visible from the outside of the door and "front", the figures made in the direction of the gaze towards this face. The directions of rotation are defined on the front views.

On observe, en figures 1 à 4, un rotor 43 de barillet 40 de serrure et des contre-goupilles 41 externes au rotor. Le rotor 43 comporte des goupilles 44 dont les longueurs correspondent au creux 55 de la clé permettant d’ouvrir la porte (voir figures 19, 23, 25, 27 et 29). De manière connue en soi, les contre-goupilles 41 sont montées sur des ressorts et servent à pousser les goupilles 44 pour qu’elles appuient sur la surface plate de la clé et pénètrent dans les creux 55. En l’absence de clé, les contre-goupilles 41 pénètrent dans les logements des goupilles les plus courtes et le rotor 40 ne peut pas tourner, ce qui interdit l’ouverture de la porte. Une fente 42 accueille la clé pourvu qu’elle présente le profil correspondant au profil 45 en entrée de la fente 42. It is observed, in Figures 1 to 4, a rotor 43 of lock cylinder 40 and counter-pins 41 external to the rotor. The rotor 43 comprises pins 44 whose lengths correspond to the recess 55 of the key allowing the door to be opened (see FIGS. 19, 23, 25, 27 and 29). In a manner known per se, the counter-pins 41 are mounted on springs and serve to push the pins 44 so that they press on the flat surface of the key and enter the recesses 55. In the absence of a key, the cross pins 41 enter the slots of the shorter pins and the rotor 40 cannot turn , which prohibits the opening of the door. A slot 42 accommodates the key provided that it has the profile corresponding to the profile 45 at the entrance to the slot 42.

Selon la présente invention, deux parties de clé 53 et 54 dont prévues. La première partie de clé 53 porte les creux 55 correspondant aux longueurs de goupilles 44. La deuxième partie de clé 54 est mobile par rapport à la première partie de clé 53. De plus, les contre-goupilles 41 présentent des dimensions permettant aux têtes de ces contre-goupilles de pénétrer dans la fente 42. According to the present invention, two key parts 53 and 54 are provided. The first key part 53 carries the recesses 55 corresponding to the lengths of pins 44. The second key part 54 is movable relative to the first key part 53. In addition, the counter-pins 41 have dimensions allowing the heads to these cross-pins from entering the slot 42.

Comme illustré en figures 5 à 8, lors la première partie de clé 53 est insérée dans le rotor, elle repousse les goupilles 44 si bien que les goupilles 44 et les contre-goupilles 41 affleurent la surface cylindrique externe du rotor 43 et ce rotor est libre de tourner dans le stator qui comporte les contre-goupilles 41 et les ressorts associés. Une rotation du rotor 43 dans un premier sens, par exemple horaire, permettrait d’ouvrir la porte. As illustrated in FIGS. 5 to 8, when the first key part 53 is inserted into the rotor, it pushes the pins 44 back so that the pins 44 and the counter-pins 41 are flush with the external cylindrical surface of the rotor 43 and this rotor is free to rotate in the stator which comprises the cross-pins 41 and the associated springs. A rotation of the rotor 43 in a first direction, for example clockwise, would open the door.

Pour bloquer la rotation du rotor 43 et bloquer la première partie de clé 53 dans la fente 42, l’utilisateur faire tourner la première partie de clé 53 dans le sens inverse du premier sens, par exemple dans le sens anti-horaire (ou trigonométrique) jusqu’à ce que la fente 42 se retrouve en face des contre-goupilles 41 . To block the rotation of the rotor 43 and block the first key part 53 in the slot 42, the user rotates the first key part 53 in the opposite direction to the first direction, for example in the anti-clockwise (or trigonometric ) until the slot 42 is opposite the cross-pins 41 .

Comme illustré en figures 5 à 8, les têtes des contre-goupilles 41 pénètrent alors dans la fente 42. A partir de ce moment, le rotor 43 ne peut plus tourner puisqu’il est bloqué en rotation par des têtes de contre-goupilles 41. Et la première partie de clé 53 ne peut plus sortir de la serrure puisqu’elle est bloquée en position par les goupilles 44 qui ont pénétré dans les creux de la première partie de clé 53. As illustrated in FIGS. 5 to 8, the heads of the counter-pins 41 then penetrate into the slot 42. From this moment, the rotor 43 can no longer rotate since it is locked in rotation by the heads of the counter-pins 41 And the first key part 53 can no longer come out of the lock since it is blocked in position by the pins 44 which have entered the recesses of the first key part 53.

Le dispositif amovible 35 de serrure à code à insérer dans un barillet 40 de serrure à clé mécanique met en œuvre cette configuration de la serrure par l’intermédiaire des deux parties 53 et 54 de clé. The removable code lock device 35 to be inserted into a cylinder 40 of a mechanical key lock implements this configuration of the lock via the two parts 53 and 54 of the key.

Comme illustré en figures 9 à 13, le dispositif 35 comporte un boîtier 51 solidaire de la première partie de clé 53 munie de reliefs correspondant aux goupilles 44 du rotor 43. Le boîtier 51 comporte : As illustrated in Figures 9 to 13, the device 35 comprises a housing 51 integral with the first key part 53 provided with reliefs corresponding to the pins 44 of the rotor 43. The housing 51 comprises:

- une deuxième partie de clé 54 mobile par rapport au boîtier 51 , - a second key part 54 movable relative to the housing 51,

- un moyen 50 de réception de codes candidats et - a means 50 for receiving candidate codes and

- un moyen 49 de mise en mouvement linéaire de la deuxième partie de clé 54 dans la fente 42 du rotor 43 après réception d’un code candidat correspondant à un code secret prédéterminé. - A means 49 for setting the second key part 54 in linear motion in the slot 42 of the rotor 43 after reception of a candidate code corresponding to a predetermined secret code.

La deuxième partie de clé 54 coulisse dans une pièce centrale 52 du boîtier 51 solidaire de la première partie de clé 53. Préférentiellement, cette pièce centrale 52 présente un profil de sortie correspondant au profil d’entrée de la fente 42. On note que ces profils se poursuivent dans toute la fente 42 et, préférentiellement, dans toute la pièce centrale 52, pour guider la translation de la deuxième partie de clé 54. The second key part 54 slides in a central part 52 of the housing 51 integral with the first key part 53. Preferably, this central part 52 has an exit profile corresponding to the entry profile of the slot 42. It is noted that these profiles continue throughout the slot 42 and, preferably, throughout the central piece 52, to guide the translation of the second key part 54.

La deuxième partie de clé 54 complète la première partie de clé 53 pour constituer la clé qui permet d’ouvrir la serrure et la porte, comme illustré en figures 12 et 13. The second key part 54 completes the first key part 53 to constitute the key which makes it possible to open the lock and the door, as illustrated in figures 12 and 13.

Le moyen 50 de réception de codes candidats illustré dans les figures est une serrure à code, représentée avec quatre rouleaux. Cependant, tout autre moyen, mécanique, magnétique ou électronique, de réception de codes candidats et de vérification de correspondance du code candidat avec un code prédéterminé peut remplacer cet exemple de moyen 50. The means 50 for receiving candidate codes shown in the figures is a code lock, shown with four rollers. However, any other means, mechanical, magnetic or electronic, of receiving candidate codes and of verifying that the candidate code corresponds to a predetermined code can replace this example of means 50.

Une bague 49 comporte un moyen de transformation du mouvement de rotation de cette bague 49 par rapport au boîtier 51 , en un mouvement de translation de la deuxième partie de clé 54. A ring 49 comprises a means for transforming the rotational movement of this ring 49 relative to the housing 51, into a translational movement of the second key part 54.

Au moins dans le sens de la sortie de la deuxième partie de clé 54 du boîtier 51 , la bague 49 n’est mobile en rotation par rapport à ce boîtier 51 que lorsque le code candidat saisi sur le moyen de réception 50 correspond au code secret prédéterminé. At least in the direction of the exit of the second key part 54 from the housing 51, the ring 49 is rotatable relative to this housing 51 only when the candidate code entered on the receiving means 50 corresponds to the secret code predetermined.

La bague 49 comporte, par exemple, un filetage correspondant à un filetage de la deuxième partie de clé 54 pour assurer la transformation du mouvement de rotation de la bague 49 en un mouvement de translation de la deuxième partie de clé 54. The ring 49 comprises, for example, a thread corresponding to a thread of the second key part 54 to ensure the transformation of the rotational movement of the ring 49 into a translational movement of the second key part 54.

La rotation de la bague 49 provoque, dans un premier sens, par exemple horaire, le déploiement de la deuxième partie de clé 54 parallèlement à la première partie de clé 53, jusqu’à ce que les deux parties de clé 53 et 54 constituent occupent toute la fente 42 et constituent la clé mécanique d’ouverture de la serrure. The rotation of the ring 49 causes, in a first direction, for example clockwise, the deployment of the second key part 54 parallel to the first key part 53, until the two key parts 53 and 54 constitute the entire slot 42 and constitute the mechanical key for opening the lock.

La rotation de la bague 49 provoque, dans un deuxième sens, par exemple anti-horaire, la rétractation, au moins partielle, de la deuxième partie de clé 54 dans le boîtier 51. On note que la rotation de la bague 49 dans ce deuxième sens ne nécessite pas la saisie du code secret sur le moyen 50 de réception de codes candidats. Préférentiellement, le mécanisme de transformation du mouvement comporte un ressort dont la force fait sortir la deuxième partie de clé 54 de la fente 42 du rotor 43 lorsque l’utilisateur relâche la bague 49. The rotation of the ring 49 causes, in a second direction, for example anti-clockwise, the at least partial retraction of the second key part 54 in the housing 51. It is noted that the rotation of the ring 49 in this second direction does not require the entry of the secret code on the means 50 for receiving candidate codes. Preferably, the motion transformation mechanism includes a spring, the force of which causes the second part of the key 54 to come out of the slot 42 of the rotor 43 when the user releases the ring 49.

On va maintenant décrire le fonctionnement du dispositif 35. We will now describe the operation of the device 35.

Comme illustré en figures 14 à 17, pour installer le dispositif 35 sur une serrure, l’utilisateur provoque la rétraction, au moins partielle, de la deuxième partie de clé 54 dans le boîtier 51. Il introduit alors la première partie de clé 53 dans la fente 42 du rotor 43, ce qui libère la rotation de ce rotor 43. As illustrated in FIGS. 14 to 17, to install the device 35 on a lock, the user causes the at least partial retraction of the second key part 54 into the housing 51. He then introduces the first key part 53 into the slot 42 of the rotor 43, which releases the rotation of this rotor 43.

La configuration correspondante des parties de clé 53 et 54, du rotor 43 et des contre-goupilles 41 est illustrée en figures 18 à 21. The corresponding configuration of the key parts 53 and 54, the rotor 43 and the cross pins 41 is illustrated in figures 18 to 21.

Puis, l’utilisateur fait tourner le boîtier 51 et donc le rotor 43 dans le sens opposé de l’ouverture de la serrure jusqu’à ce que la fente 42 soit en regard des contre-goupilles 41 et accueille les têtes d’au moins une partie de ces contre-goupilles 41 . La configuration correspondante des parties de clé 53 et 54, du rotor 43 et des contre-goupilles 41 est illustrée en figures 22 à 25. Then, the user rotates the case 51 and therefore the rotor 43 in the direction opposite to the opening of the lock until the slot 42 is opposite the counter-pins 41 and accommodates the heads of at least part of these pins against 41 . The corresponding configuration of the key parts 53 and 54, the rotor 43 and the cross pins 41 is illustrated in figures 22 to 25.

Dans cette configuration, la serrure est bloquée en rotation par les têtes des contre-goupilles 41 introduites dans la fente 42. La première partie de clé 53 est bloquée dans le rotor 43 par les goupilles 44 ayant pénétré dans des creux 55 de la première partie de clé 53. In this configuration, the lock is locked in rotation by the heads of the counter-pins 41 introduced into the slot 42. The first key part 53 is locked in the rotor 43 by the pins 44 having penetrated into recesses 55 of the first part of key 53.

L’utilisateur initial, par exemple le propriétaire du local ou son locataire, peut alors mettre le code secret à disposition d’un tiers à qui il autorise l’accès au local, en lui transmettant ce code secret ou en passant par un serveur de réservation de locaux. Par exemple, il s’agit d’un serveur de location de logement de courtes durées. The initial user, for example the owner of the premises or his tenant, can then make the secret code available to a third party to whom he authorizes access to the premises, by transmitting this secret code to him or by going through a server of reservation of premises. For example, this is a short-term housing rental server.

Lorsque ce tiers se présente devant le dispositif 35, il saisit le code secret sur le moyen 50 de réception de codes candidats. Puis, il active le déplacement de la deuxième partie de clé 54 dans la fente 42, ce qui a pour effet de repousser les têtes de contre-goupilles 41 à l’extérieur de la fente 42. When this third party appears before the device 35, he enters the secret code on the means 50 for receiving candidate codes. Then, it activates the movement of the second part of the key 54 in the slot 42, which has the effect of pushing the heads of the counter-pins 41 outside of the slot 42.

La configuration correspondante des parties de clé 53 et 54, du rotor 43 et des contre-goupilles 41 est illustrée en figures 26 à 29. The corresponding configuration of the key parts 53 and 54, the rotor 43 and the cross pins 41 is illustrated in figures 26 to 29.

Le rotor 43 peut alors tourner et provoquer l’ouverture de la serrure et de la porte. The rotor 43 can then turn and cause the lock and the door to open.

On observe, en figure 30, un mode de réalisation particulier 90 du procédé objet de l’invention, dans lequel des moyens de communication électroniques sont mis en œuvre à la place des moyens mécaniques 49 et 50 décrits ci-dessus. We observe, in FIG. 30, a particular embodiment 90 of the method which is the subject of the invention, in which electronic means of communication are implemented instead of the mechanical means 49 and 50 described above.

Ce procédé 90 comporte, préliminaire, du côté du tiers (à gauche en figure 30) :This process 90 comprises, preliminary, on the side of the third party (on the left in figure 30):

- une étape 91 de réservation du local, par des moyens connus, par exemple une plateforme de réservation de la toile et - a step 91 of reserving the room, by known means, for example a canvas reservation platform and

- une étape 92 d’obtention d’un code secret à saisir sur le dispositif 35. - a step 92 for obtaining a secret code to be entered on the device 35.

Parallèlement, sont réalisées, du côté du fournisseur du local : At the same time, are carried out, on the side of the supplier of the premises:

Only in case of correspondence, the device performs a step 101 of unlocking the lock by moving the second key part 54 to that it pushes back all the heads of the pins 41 that have entered the slot 42. The third party then performs a step 102 of rotation of the device 35 which triggers the opening of the lock and of the door.

On donne, ci-dessous, d’autres variantes et explications du fonctionnement de l’invention.Other variants and explanations of the operation of the invention are given below.

L’interface 50 de fourniture, par le tiers, du code secret peut être aussi bien mécanique qu’électronique, voire comporter une interface mécanique, telle que celle illustrée dans les figures et une interface électronique. Le principe du dispositif est d’utiliser deux parties de clé. Ces deux parties clé rassemblées côte à côte forment la lame d’une clé de barillet standard. Sont concernés tous les barillets de serrure à goupilles, contre-goupilles et clés munies de creux où pénètrent les goupilles, réversibles ou non. Ces types de barillets représentent la majorité des barillets de serrure utilisés pour les portes d’entrée (locaux, appartements, maisons...) dans le monde. The interface 50 for supplying, by the third party, the secret code can be both mechanical and electronic, or even include a mechanical interface, such as that illustrated in the figures, and an electronic interface. The principle of the device is to use two key parts. These two key parts put together side by side form the blade of a standard cylinder key. All lock cylinders with pins, counter-pins and keys fitted with recesses into which the pins penetrate, whether reversible or not, are concerned. These types of cylinders represent the majority of lock cylinders used for entrance doors (premises, apartments, houses, etc.) in the world.

Dans des modes de réalisation, à la deuxième partie de clé est ajouté une tige venant traverser la partie centrale du barillet, l’entraineur, jusqu’à l’autre rotor se trouvant dans l’autre partie du barillet. Cette action a pour effet de coupler le rotor extérieur avec le rotor intérieur et donc de bloquer les deux rotors. In some embodiments, to the second key part is added a rod passing through the central part of the barrel, the trainer, to the other rotor located in the other part of the barrel. This action has the effect of coupling the outer rotor with the inner rotor and therefore of blocking the two rotors.

En variante du moyen de mise en mouvement de la deuxième partie de clé 54, on utilise deux axes l’un dans l’autre. Le premier axe tient la deuxième partie de clé 54, et le second axe est rattaché à un loquet ou une bague permettant de le faire tourner. Un des axes a des cannelures internes sur une extrémité, et l’autre axe a des cannelures externes sur une de ses extrémités. En position bloquée, les deux axes sont libres l’un par rapport à l’autre, débrayés, donc l’axe qui comporte le loquet ou la bague n’entraine pas la rotation de l’axe qui comporte la clé. En position débloquée, il est alors nécessaire de tirer ou de pousser le loquet ou la bague, ce qui a pour but de mettre en face les cannelures des deux axes et donc d’embrayer les deux axes ensemble. La rotation du loquet ou de la bague entraine la rotation de la clé. As a variant of the means for setting the second key part 54 in motion, two axes are used one inside the other. The first pin holds the second key portion 54, and the second pin is attached to a latch or ring allowing it to be rotated. One of the axles has internal splines on one end, and the other axle has external splines on one end. In the locked position, the two axes are free relative to each other, disengaged, so the axis which includes the latch or the ring does not cause the rotation of the axis which includes the key. In the unlocked position, it is then necessary to pull or push the latch or the ring, the purpose of which is to bring the splines of the two axes face to face and therefore to engage the two axes together. The rotation of the latch or the ring causes the rotation of the key.

Dans d’autres modes de réalisation (non représentés), le moyen de mise en mouvement linéaire de la deuxième partie de clé dans la fente du rotor comporte un bouton-poussoir solidaire de la deuxième partie de clé, ce bouton poussoir étant retenu en position par le moyen de réception de codes candidats. Préférentiellement, ce bouton-poussoir est muni d’un ressort de rappel dont la force fait ressortir au moins partiellement la deuxième partie de clé 54 de la fente 42. In other embodiments (not shown), the means for setting the second key part in linear motion in the slot of the rotor comprises a push-button integral with the second key part, this push-button being retained in position by means of receiving candidate codes. Preferably, this push-button is provided with a return spring, the force of which at least partially brings out the second part of the key 54 from the slot 42.

Dans des modes de réalisation (non représentés), le boîtier 51 comporte une réserve d’énergie électrique, une interface électronique de réception d’un code candidat et une unité centrale de reconnaissance du code prédéterminé. Préférentiellement, l’interface de réception comporte un moyen de communication avec un terminal mobile communiquant. In embodiments (not shown), the box 51 includes an electrical power reserve, an electronic interface for receiving a candidate code and a central unit for recognizing the predetermined code. Preferably, the reception interface comprises a means of communication with a communicating mobile terminal.

Dans des modes de réalisation (non représentés), le boîtier 51 comporte au moins un moteur de mise en mouvement de la deuxième partie de la clé 54. Bien entendu, les caractéristiques particulières de tous les modes de réalisation décrits ci- dessus peuvent être combinées pour former d’autres dispositif amovible de serrure à code à insérer dans un barillet de serrure à clé mécanique. In embodiments (not shown), the box 51 includes at least one motor for setting the second part of the key 54 in motion. Of course, the particular characteristics of all the embodiments described above can be combined to form other removable code lock devices to be inserted into a lock cylinder with a mechanical key.
