Description

L'invention concerne une serrure électronique.The invention relates to an electronic lock.

Le déposant connaît des serrures électroniques, destinées à être commandées par une clé comportant des moyens électroniques pour commander le déverrouillage de la serrure. Ces serrures comportent :

  • un stator et un rotor monté en rotation dans le stator et muni d'un canal dans lequel la clé peut être introduite,
  • un organe de blocage du rotor déplaçable dans un logement du stator entre une position de blocage dans laquelle il est en prise avec le rotor pour bloquer sa rotation et une position escamotée dans laquelle il libère la rotation du rotor,
  • une butée fixée sans aucun degré de liberté au stator, et
  • un levier de verrouillage apte à tourner autour d'un premier axe, en réponse à un ordre de déverrouillage électrique, entre une position de verrouillage dans laquelle le levier de verrouillage est susceptible de venir en appui d'un côté sur la butée et, d'un autre côté, sur l'organe de blocage pour maintenir l'organe de blocage dans sa position de blocage, et une position de déverrouillage dans laquelle l'organe de blocage est libre de quitter sa position de blocage.
The applicant knows electronic locks, intended to be controlled by a key comprising electronic means for controlling the unlocking of the lock. These locks include:
  • a stator and a rotor rotatably mounted in the stator and provided with a channel into which the key can be inserted,
  • a rotor locking member displaceable in a stator housing between a locking position in which it engages the rotor to block its rotation and a retracted position in which it releases the rotation of the rotor,
  • a stop fixed without any degree of freedom to the stator, and
  • a locking lever adapted to rotate about a first axis, in response to an electric unlocking command, between a locking position in which the locking lever is able to bear on one side on the stop and, d on the other hand, on the locking member for holding the locking member in its locking position, and an unlocking position in which the locking member is free to leave its locking position.

De telles serrures sont par exemple divulguées dans les demandes de brevet EP 10161789 ( EP2248971A1 ) et EP 11175117 ( EP2 412 901A1 ).Such locks are for example disclosed in patent applications EP 10161789 ( EP2248971A1 ) and EP 11175117 ( EP2 412 901A1 ).

Lorsqu'une clé est introduite dans le canal puis tournée, une force s'exerce sur l'organe de blocage du rotor pour déplacer cet organe de sa position de blocage vers sa position escamotée. Parallèlement à l'exercice de cette force, si c'est la clé adéquate qui est introduite, un ordre de déverrouillage électrique est généré, par exemple suite à la vérification d'un code numérique contenu dans la clé. En réponse à cet ordre de déverrouillage électrique, le levier de verrouillage est déplacé vers sa position de déverrouillage. Cependant, il se peut que l'ordre de déverrouillage électrique intervienne après que la clé ait exercé sa force sur l'organe de blocage. Il se peut aussi que la clé introduite ne soit pas celle autorisée à ouvrir la serrure, en cas d'infraction notamment, auquel cas l'ordre de déverrouillage électrique n'est pas transmis. Dans ces deux cas, l'organe de blocage appuie d'un côté du levier de verrouillage. En réponse, le levier de verrouillage se déplace jusqu'à ce qu'il vienne en appui, d'un autre côté, sur la butée fixe. Le levier de verrouillage est alors coincé dans sa position de verrouillage. Ce déplacement du levier de verrouillage en réponse à l'appui de l'organe de blocage déforme son axe de rotation. La déformation du premier axe augmente les frottements entre cet axe et le levier de verrouillage, ce qui peut empêcher ensuite le déplacement du levier de verrouillage vers sa position de déverrouillage. De plus, des déformations répétées de cet axe de rotation peuvent entraîner sa déformation irréversible, voire sa rupture.When a key is inserted into the channel and then turned, a force is exerted on the rotor locking member to move this member from its locking position to its retracted position. In parallel with the exercise of this force, if it is the appropriate key that is introduced, an electrical unlock command is generated, for example following the verification of a digital code contained in the key. In response to this electrical unlocking command, the lock lever is moved to its unlock position. However, it may be that the electric unlocking order occurs after the key has exerted its force on the locking member. It is also possible that the key introduced is not the one authorized to open the lock, especially in the event of a breach, in which case the electric unlocking command is not transmitted. In these two cases, the locking member presses on one side of the locking lever. In response, the locking lever moves until it bears, on the other hand, on the fixed stop. The locking lever is then stuck in its locking position. This movement of the locking lever in response to the support of the locking member deforms its axis of rotation. The deformation of the first axis increases the friction between this axis and the locking lever, which can then prevent the movement of the locking lever to its unlocked position. In addition, repeated deformations of this axis of rotation can cause its irreversible deformation, or even rupture.

L'invention vise à remédier à cet inconvénient.The invention aims to remedy this drawback.

L'invention concerne donc une serrure conforme à la revendication 1.The invention therefore relates to a lock according to claim 1.

Une telle serrure limite la déformation mécanique du premier axe en réponse à l'appui de l'organe de blocage. En effet, en réponse à cet appui, l'extrémité du premier axe se déplace dans le rail ce qui permet le déplacement du levier de verrouillage vers la butée fixe tout en limitant ou en éliminant la déformation du premier axe. La solidité et la durée de vie d'une telle serrure sont ainsi améliorées.Such a lock limits the mechanical deformation of the first axis in response to the support of the locking member. Indeed, in response to this support, the end of the first axis moves in the rail which allows the movement of the locking lever to the fixed stop while limiting or eliminating the deformation of the first axis. The strength and the life of such a lock are thus improved.

Les modes de réalisation de cette serrure peuvent comporter en outre une ou plusieurs des caractéristiques des revendications dépendantes.The embodiments of this lock may further comprise one or more of the features of the dependent claims.

Les modes de réalisation de cette serrure présentent en outre les avantages suivants :

  • ▪ l'utilisation du deuxième rail permet un déplacement équilibré du premier axe grâce aux deux rails symétriques se trouvant à chaque extrémité, ce qui évite ainsi les déformations de cet axe,
  • ▪ le bras de mémorisation permet de mémoriser mécaniquement l'ordre de déverrouillage électrique, même si le levier de verrouillage est immobilisé dans sa position de verrouillage, lorsque cet ordre est généré,
  • ▪ les plaques à chaque extrémité du premier axe sont un moyen simple d'assurer le coulissement de l'axe dans les deux rails,
  • ▪ laisser libre la seconde extrémité du premier axe simplifie la réalisation de la serrure,
  • ▪ le deuxième axe disjoint du premier et fixé au stator permet au bras de mémorisation d'assurer la même fonction, et cet axe ne subissant pas les mêmes pressions que le premier axe, il n'est pas nécessaire qu'il soit déplaçable, ce qui permet ici de n'avoir qu'un seul rail,
  • ▪ la plaque à l'extrémité du premier axe constitue un moyen simple pour assurer le coulissement de l'axe dans le premier rail.
The embodiments of this lock also have the following advantages:
  • ▪ the use of the second rail allows a balanced movement of the first axis thanks to the two symmetrical rails at each end, which thus avoids the deformations of this axis,
  • ▪ the storage arm makes it possible to mechanically memorize the electric unlocking command, even if the locking lever is immobilized in its locking position, when this command is generated,
  • ▪ the plates at each end of the first axis are a simple way to ensure the sliding of the axis in the two rails,
  • ▪ leave free the second end of the first axis simplifies the realization of the lock,
  • ▪ the second axis disjointed from the first and fixed to the stator allows the storage arm to perform the same function, and this axis does not undergo the same pressures as the first axis, it is not necessary that it is movable, this which allows here to have only one rail,
  • ▪ the plate at the end of the first axis is a simple way to ensure the sliding of the axis in the first rail.

Dans la suite de cette description, les caractéristiques et fonctions bien connues de l'homme du métier ne sont pas décrites en détail.In the remainder of this description, the features and functions well known to those skilled in the art are not described in detail.

La figure 1 représente un barillet 2 d'une serrure à double barillet dont l'autre barillet n'est pas montré dans la figure 1. Ce barillet 2 s'étend en profondeur le long d'une direction Z perpendiculaire à des directions horizontale et verticale, respectivement X et Y. Dans la suite de la description, les termes « inférieur », « supérieur », «bas », « haut », « dessus » et « dessous » sont définis en référence à la direction Y.The figure 1 represents a barrel 2 of a double barrel lock whose other barrel is not shown in the figure 1 . This barrel 2 extends in depth along a direction Z perpendicular to horizontal and vertical directions, respectively X and Y. In the remainder of the description, the terms "lower", "upper", "lower", " top "," above "and" below "are defined with reference to the Y direction.

Le barillet 2 est par exemple identique à celui décrit dans la demande de brevet EP11175117 sauf qu'il comporte un mécanisme pour protéger un axe de rotation d'un levier de verrouillage. Ce mécanisme est décrit en référence aux figures 2 et suivantes.The barrel 2 is for example identical to that described in the patent application EP11175117 except that it has a mechanism for protecting an axis of rotation of a locking lever. This mechanism is described with reference to figures 2 and following.

Les deux barillets sont logés de manière classique dans une porte (non montrée) et sont disposés symétriquement par rapport au plan moyen P de la porte. Les deux barillets sont positionnés et reliés de manière classique l'un à l'autre par une tige de liaison (non montrée) qui présente en son milieu un renflement servant d'entretoise pour maintenir un écartement prédéfini entre les deux barillets. Dans l'espace entre les deux barillets est disposé, de façon classique, un panneton (non montré) qui peut être entraîné en rotation par un rotor 4 de l'un ou l'autre des deux barillets lorsqu'une clé appropriée, par exemple une clé 5, est introduite dans un canal 6 du rotor 4 et tournée manuellement par un utilisateur.The two barrels are housed in a conventional manner in a door (not shown) and are arranged symmetrically with respect to the average plane P of the door. The two barrels are positioned and connected in a conventional manner to one another by a connecting rod (not shown) which has in its middle a bulge serving as a spacer to maintain a predefined spacing between the two barrels. In the space between the two barrels is arranged, conventionally, a bit (not shown) which can be rotated by a rotor 4 of one or the other of the two barrels when an appropriate key, for example a key 5 is introduced into a channel 6 of the rotor 4 and manually rotated by a user.

Lorsqu'il est entraîné en rotation par la clé 5 et le rotor 4, le panneton commande un mécanisme de serrure classique (non montré) qui provoque le déplacement d'au moins un pêne de la serrure dans un sens permettant l'ouverture de la porte ou dans un sens interdisant l'ouverture de la porte selon le sens de rotation de la clé 5.When rotated by the key 5 and the rotor 4, the bit controls a conventional lock mechanism (not shown) which causes the displacement of at least one bolt of the lock in a direction allowing the opening of the lock. door or in a direction prohibiting the opening of the door according to the direction of rotation of the key 5.

Le rotor 4 du barillet 2 est monté en rotation dans un stator profilé 7. Le stator 7 est lui-même logé dans un fourreau extérieur 8 ayant le même profil. Dans l'exemple, le stator 7 a un profil normalisé, dit « européen ». Toujours dans l'exemple, l'axe de rotation du rotor 4 est parallèle à la direction Z.The rotor 4 of the barrel 2 is rotatably mounted in a profiled stator 7. The stator 7 is itself housed in an outer sheath 8 having the same profile. In the example, the stator 7 has a standardized profile, called "European". Still in the example, the axis of rotation of the rotor 4 is parallel to the direction Z.

Le barillet 2 comporte de manière classique plusieurs paires de goupilles de stator et de rotor, qui sont disposées par paires, bout à bout, dans des paires correspondantes de logements alignés formés respectivement dans le stator 7 et dans le rotor 4. Étant donné que cet arrangement des goupilles de rotor et de stator est bien connu, celui-ci n'a pas été représenté pour simplifier la figure 1.The barrel 2 conventionally comprises several pairs of stator and rotor pins, which are arranged in pairs, end to end, in corresponding pairs of aligned housings respectively formed in the stator 7 and in the rotor 4. arrangement of the rotor and stator pins is well known, this one has not been shown to simplify the figure 1 .

La clé 5, qui a par exemple une section transversale sensiblement rectangulaire, présente sur au moins une de ses deux grandes faces, de préférence sur ses deux grandes faces, des empreintes et/ou des reliefs qui coopèrent avec les goupilles de rotor. Les empreintes et/ou les reliefs sont conformés et les longueurs des goupilles de rotor sont choisies de telle façon que, si une bonne clé 5 est introduite dans le canal 6 du rotor 4, l'interface entre chaque goupille de rotor et la goupille de stator associée se trouve exactement à l'interface entre le rotor 4 et le stator 7. Dans ces conditions, le rotor 4 peut être tourné manuellement à l'aide de la clé 5, sous réserve qu'un mécanisme 9 de verrouillage électrique soit lui-même dans un état déverrouillé. Le mécanisme 9 est ici différent de celui décrit dans la demande EP11175117 , afin de pallier aux inconvénients précédemment cités. Il est décrit plus loin. Le barillet 2 comporte un organe supplémentaire de blocage 10 destiné à empêcher le rotor 4 de tourner tant qu'un code numérique approprié contenu dans une mémoire (non montrée) logée dans la clé 5 n'a pas été introduit dans un circuit électronique 12 logé dans le barillet 2. Sur la figure 1, le circuit 12 est disposé à l'extérieur du barillet 2 afin de simplifier le dessin. Ce circuit 12, lorsqu'il reçoit le code approprié, génère un ordre de déverrouillage électrique. Par exemple, il commande le mécanisme 9 pour permettre le déblocage du rotor 4.The key 5, which has for example a substantially rectangular cross section, has on at least one of its two large faces, preferably on its two large faces, indentations and / or reliefs which cooperate with the rotor pins. The imprints and / or the reliefs are shaped and the lengths of the rotor pins are chosen so that, if a good key 5 is inserted into the channel 6 of the rotor 4, the interface between each rotor pin and the pin of associated stator is located exactly at the interface between the rotor 4 and the stator 7. Under these conditions, the rotor 4 can be rotated manually using the key 5, provided that a mechanism 9 electric lock is him - even in an unlocked state. The mechanism 9 is here different from that described in the application EP11175117 to overcome the disadvantages mentioned above. It is described later. The barrel 2 comprises an additional locking member 10 for preventing the rotor 4 from rotating as long as an appropriate digital code contained in a memory (not shown) housed in the key 5 has not been introduced into an electronic circuit 12 housed in the barrel 2. On the figure 1 , the circuit 12 is disposed outside the barrel 2 to simplify the drawing. This circuit 12, when it receives the appropriate code, generates an electric unlock command. For example, it controls the mechanism 9 to enable the unlocking of the rotor 4.

Par exemple, le code est transmis de la clé 5 au circuit électronique 12 de la serrure par voie hertzienne ou par l'intermédiaire de contacts électriques. Pour une transmission par voie hertzienne, de préférence, la clé 5 est équipée d'un transpondeur et le circuit 12 est équipé d'un lecteur de transpondeurs.For example, the code is transmitted from the key 5 to the electronic circuit 12 of the lock via radio relay or via electrical contacts. For transmission by radio, preferably, the key 5 is equipped with a transponder and the circuit 12 is equipped with a transponder reader.

Lorsque la clé 5 est introduite dans le canal 6 du rotor 4, le code numérique contenu dans la mémoire de la clé 5 est transmis au circuit 12. Par exemple, le circuit 12 compare alors le code transmis à au moins un code préenregistré dans une mémoire. En cas de concordance des deux codes, le circuit 12 génère l'ordre de déverrouillage électrique du mécanisme 9.When the key 5 is inserted into the channel 6 of the rotor 4, the digital code contained in the memory of the key 5 is transmitted to the circuit 12. For example, the circuit 12 then compares the transmitted code with at least one prerecorded code in a memory. In case of agreement between the two codes, the circuit 12 generates the electric unlocking command of the mechanism 9.

Dans la forme de réalisation de la serrure représentée sur les dessins, l'organe supplémentaire de blocage 10 est une goupille de stator qui coopère avec une goupille 14 de rotor correspondante de manière à ce que si la bonne clé est introduite dans le canal 6, l'interface entre ces deux goupilles se trouve exactement à l'interface du stator 7 et du rotor 4. Toutefois, contrairement aux autres goupilles de stator, l'organe de blocage 10 est prolongé par un téton conique 16, à sommet arrondi, qui est engagé dans un évidement tronconique correspondant 18 formé dans la goupille de rotor 14. Dans l'exemple, l'organe 10 est réalisé dans un matériau magnétique.In the embodiment of the lock shown in the drawings, the additional locking member 10 is a stator pin which cooperates with a corresponding rotor pin 14 so that if the correct key is inserted into the channel 6, the interface between these two pins is exactly at the interface of the stator 7 and the rotor 4. However, unlike the other stator pins, the locking member 10 is extended by a conical stud 16, with a top rounded, which is engaged in a corresponding frustoconical recess 18 formed in the rotor pin 14. In the example, the member 10 is made of a magnetic material.

Dans cette description, par « matériau magnétique » on désigne un matériau dont la perméabilité magnétique relative est strictement supérieure à 1 et, de préférence, supérieure à 100 ou 1000. Par exemple, le matériau est un matériau ferromagnétique tel que de l'acier.In this description, the term "magnetic material" denotes a material whose relative magnetic permeability is strictly greater than 1 and, preferably, greater than 100 or 1000. For example, the material is a ferromagnetic material such as steel.

L'organe 10 est déplaçable entre une position de blocage (représentée sur la figure 1) dans laquelle il est en prise avec le rotor 4 pour bloquer sa rotation et une position escamotée dans laquelle il libère la rotation du rotor 4. A cet effet, l'organe 10 est monté coulissant dans un logement cylindrique 20 qui est formé dans le stator 7 et qui est aligné axialement avec un logement 22 dans le rotor 4 dans lequel coulisse la goupille 14 de rotor. L'organe 10 comprend par ailleurs une barrette transversale 24 qui est formée d'un seul tenant avec l'organe 10, à l'extrémité inférieure de celui-ci. Une des extrémités de la barrette 24 est conformée pour former un talon 26. Par exemple, les deux côtés de la barrette 24 sont engagés et guidés dans des fentes (non représentées) formées dans la paroi du logement 20. Ces fentes empêchent l'organe de blocage 10 de tourner quand il se déplace dans le logement cylindrique 20.The member 10 is movable between a locking position (represented on the figure 1 ) in which it is engaged with the rotor 4 to block its rotation and a retracted position in which it releases the rotation of the rotor 4. For this purpose, the member 10 is slidably mounted in a cylindrical housing 20 which is formed in the stator 7 and which is aligned axially with a housing 22 in the rotor 4 in which slides the pin 14 rotor. The member 10 further comprises a transverse bar 24 which is formed integrally with the member 10 at the lower end thereof. One end of the bar 24 is shaped to form a heel 26. For example, the two sides of the bar 24 are engaged and guided in slots (not shown) formed in the wall of the housing 20. These slots prevent the organ 10 to rotate when it moves in the cylindrical housing 20.

Le mécanisme 9 va maintenant être décrit plus en détail en référence aux figures 2, 3, 4 et 5.Mechanism 9 will now be described in more detail with reference to figures 2 , 3, 4 and 5 .

Le mécanisme 9 comporte une cavité 32. La cavité 32 est une zone évidée disposée à l'intérieur du stator 7. Dans l'exemple, la cavité 32 est située en dessous du logement 20 et reçoit la barrette 24.The mechanism 9 comprises a cavity 32. The cavity 32 is a recessed zone disposed inside the stator 7. In the example, the cavity 32 is located below the housing 20 and receives the bar 24.

Le mécanisme 9 comprend un ressort 30 apte à solliciter l'organe 10 vers sa position de blocage lorsque les logements 20 et 22 sont en vis-à-vis. Ce ressort 30 s'appuie, à son extrémité inférieure, contre le fond de la cavité 32 et à son extrémité supérieure contre le dessous du talon 26 de l'organe 10.The mechanism 9 comprises a spring 30 adapted to bias the member 10 towards its locking position when the housings 20 and 22 are vis-à-vis. This spring 30 rests, at its lower end, against the bottom of the cavity 32 and at its upper end against the underside of the heel 26 of the member 10.

Le mécanisme 9 comprend également un levier 34 de verrouillage déplaçable entre :

  • une position de verrouillage dans laquelle le levier 34 est susceptible de maintenir l'organe 10 de blocage dans sa position de blocage, et
  • une position de déverrouillage dans laquelle l'organe 10 de blocage est libre de quitter sa position de blocage.
The mechanism 9 also comprises a locking lever 34 movable between:
  • a locking position in which the lever 34 is capable of holding the locking member 10 in its locking position, and
  • an unlocking position in which the locking member 10 is free to leave its locking position.

Le levier 34 est disposé dans la cavité 32. Ce levier 34 s'étend principalement le long d'un axe longitudinal. Ici, le levier 34 est en position de verrouillage lorsque son axe longitudinal est vertical, c'est-à-dire qu'il est parallèle à la direction Y. Le levier 34 est en position de déverrouillage lorsque son axe longitudinal s'étend selon une direction oblique appartenant au plan formé par les directions X et Y et inclinée d'au moins 10° et, de préférence, d'au moins 45° par rapport au plan vertical YZ. Sur les figures 2 et 5, le levier 34 est en position de verrouillage.The lever 34 is disposed in the cavity 32. This lever 34 extends mainly along a longitudinal axis. Here, the lever 34 is in the locking position when its longitudinal axis is vertical, that is to say that it is parallel to the direction Y. The lever 34 is in the unlocked position when its longitudinal axis extends according to an oblique direction belonging to the plane formed by the X and Y directions and inclined by at least 10 ° and preferably at least 45 ° with respect to the vertical plane YZ. On the figures 2 and 5 the lever 34 is in the locking position.

Le levier 34 comporte une extrémité supérieure 36 et une extrémité inférieure 38 toutes les deux situées sur son axe longitudinal. Lorsque le levier 34 est en position de verrouillage, les extrémités 36 et 38 sont susceptibles de venir en appui respectivement sur la barrette 24 de l'organe 10 de blocage, et, à l'opposé, sur une butée 40 fixée sans aucun degré de liberté au stator. Ici, la butée 40 est une partie inférieure du stator.The lever 34 has an upper end 36 and a lower end 38 both located on its longitudinal axis. When the lever 34 is in the locking position, the ends 36 and 38 may bear respectively on the bar 24 of the locking member 10, and, on the opposite, on a stop 40 fixed without any degree of freedom to the stator. Here, the stop 40 is a lower part of the stator.

Le levier 34 est conformé pour que lorsqu'il est en position de verrouillage, en absence d'appui de l'organe 10 sur le levier 34, un jeu 42 (visible sur la figure 5) demeure entre l'extrémité 36 du levier 34 et la barrette 24, et un jeu 44 (visible sur la figure 5) demeure entre l'extrémité 38 et la butée 40. Ces jeux 42 et 44 sont suffisamment grands pour permettre au levier 34 de tourner de sa position de verrouillage vers sa position de déverrouillage.The lever 34 is shaped so that when in the locking position, in the absence of support of the member 10 on the lever 34, a clearance 42 (visible on the figure 5 ) remains between the end 36 of the lever 34 and the bar 24, and a clearance 44 (visible on the figure 5 ) remains between the end 38 and the stop 40. These games 42 and 44 are sufficiently large to allow the lever 34 to rotate from its locking position to its unlocking position.

La forme et les caractéristiques du levier 34 peuvent être par exemple identiques à celles décrites plus en détail dans la demande de brevet EP 1175117 .The shape and characteristics of the lever 34 may for example be identical to those described in more detail in the patent application. EP 1175117 .

Ici, le déplacement du levier 34 de sa position de verrouillage à sa position de déverrouillage est réalisé par rotation du levier 34 dans le sens horaire. A cet effet, le levier 34 est monté libre en rotation sur un axe 46. L'axe 46 est parallèle à la direction Z. Par exemple, le levier 34 est monté en rotation autour de l'axe 46 grâce à un palier, par exemple un palier à rubis. Ce type de roulement est fragile et nécessite que l'axe 46 ne soit pas déformé lors de l'utilisation de la serrure. A cet effet, l'axe 46 est déplaçable d'une position haute, dans laquelle le jeu 44 est à sa valeur maximale, lorsque l'organe 10 n'est pas en appui sur le levier 34, vers une position basse dans laquelle le jeu 44 est nul. Pour que ce déplacement soit possible sans tordre l'axe 46, une première extrémité de l'axe 46 comporte ici une plaque 48. Cette plaque est représentée comme étant transparente sur la figure 2 de manière à rendre visibles les pièces qui sont derrière. Toutefois, cette plaque 48 n'a pas besoin d'être transparente. Elle est fixée sans aucun degré de liberté à une extrémité 49 (figure 3) de l'axe 46. Ici, la plaque 48 s'étend dans un plan vertical parallèle au plan YX et a une forme rectangulaire. La plaque 48 est montée à coulissement dans un rail 50 (visible sur la figure 4). Le rail 50 est ici constitué de deux rainures rectilignes 52 et 54 (figure 4) en vis-à-vis et formées dans le stator 7. Les rainures 52 et 54 s'étendent verticalement et sont aptes à recevoir respectivement chacune un bord vertical de la plaque 48. Ainsi, la plaque 48 est déplaçable en translation verticale dans le rail 50, c'est-à-dire selon la direction F (figure 2).Here, the movement of the lever 34 from its locking position to its unlocking position is achieved by rotation of the lever 34 in the clockwise direction. For this purpose, the lever 34 is rotatably mounted on an axis 46. The axis 46 is parallel to the direction Z. For example, the lever 34 is rotatably mounted about the axis 46 by means of a bearing, for example example a ruby bearing. This type of bearing is fragile and requires that the axis 46 is not deformed when using the lock. For this purpose, the axis 46 is movable from a high position, in which the clearance 44 is at its maximum value, when the member 10 is not resting on the lever 34, towards a low position in which the game 44 is zero. For this displacement to be possible without distorting the axis 46, a first end of the axis 46 here comprises a plate 48. This plate is represented as being transparent on the figure 2 in order to make visible the pieces that are behind. However, this plate 48 does not need to be transparent. It is fixed without any degree of freedom at one end 49 ( figure 3 ) of the axis 46. Here, the plate 48 extends in a vertical plane parallel to the plane YX and has a rectangular shape. The plate 48 is slidably mounted in a rail 50 (visible on the figure 4 ). The rail 50 here consists of two rectilinear grooves 52 and 54 ( figure 4 ) The grooves 52 and 54 extend vertically and are respectively able to receive a vertical edge of the plate 48. Thus, the plate 48 is displaceable in vertical translation in the vertical direction. rail 50, that is to say in the direction F ( figure 2 ).

Le mécanisme 9 comporte également un moyen de rappel sollicitant l'axe 46 vers sa position haute. Par exemple, le moyen de rappel est ici un ressort 56. Ce ressort 56 s'appuie, à son extrémité inférieure, contre le fond de la cavité 32, et, à son extrémité supérieure, contre un bord horizontal inférieur de la plaque 48.The mechanism 9 also comprises a biasing means biasing the axis 46 towards its upper position. For example, the return means here is a spring 56. This spring 56 rests, at its lower end, against the bottom of the cavity 32, and, at its upper end, against a lower horizontal edge of the plate 48.

Le mécanisme 9 comporte également un bras 58 de mémorisation apte à mémoriser un ordre de déverrouillage électrique même si le levier 34 est immobilisé par l'organe 10. Le bras 58 est déplaçable entre:

  • une position de repos, et
  • une position de mémorisation, en réponse à l'ordre de déverrouillage électrique.
The mechanism 9 also comprises a storage arm 58 capable of storing an electric unlocking command even if the lever 34 is immobilized by the member 10. The arm 58 can be moved between:
  • a rest position, and
  • a storage position, in response to the electrical unlock command.

Ici, le bras 58 s'étend principalement le long d'un axe longitudinal. Il est en position de repos lorsque son axe longitudinal est vertical. Le bras 58 est en position de mémorisation lorsqu'une extrémité supérieure du bras 58 est en butée contre le talon 26. Son axe longitudinal s'étend alors selon une direction oblique, appartenant au plan parallèle aux directions X et Y et inclinée par rapport au plan YZ. Sur la figure 2, le bras 58 est en position de repos.Here, the arm 58 extends mainly along a longitudinal axis. It is in the rest position when its longitudinal axis is vertical. The arm 58 is in the storage position when an upper end of the arm 58 is in abutment against the heel 26. Its longitudinal axis then extends in an oblique direction, belonging to the plane parallel to the X and Y directions and inclined relative to the YZ plan. On the figure 2 the arm 58 is in the rest position.

Le bras 58 est disposé à l'intérieur de la cavité 32. Ici, le bras 58 est monté libre en rotation sur un deuxième axe 60 (visible sur la figure 3). Le déplacement du bras 58 de sa position de repos à sa position de mémorisation s'effectue par une rotation dans le sens horaire. L'axe 60 est mécaniquement séparé du premier axe 46, et s'étend dans une direction parallèle à la direction de l'axe 46. Le terme parallèle englobe ici le cas où les deux directions sont confondues. Ici, l'axe 60 s'étend dans le prolongement de l'axe 46. L'axe 60 est fixé sans aucun degré de liberté au stator 7. Ainsi, il ne subit aucune déformation en cas d'appui de l'organe 10 sur le levier 34 car aucune contrainte radiale ne s'exerce sur le bras 58.The arm 58 is disposed inside the cavity 32. Here, the arm 58 is mounted free to rotate on a second axis 60 (visible on the figure 3 ). The movement of the arm 58 from its rest position to its storage position is effected by a rotation in the clockwise direction. The axis 60 is mechanically separated from the first axis 46, and extends in a direction parallel to the direction of the axis 46. The parallel term here encompasses the case where the two directions are merged. Here, the axis 60 extends in the extension of the axis 46. The axis 60 is fixed without any degree of freedom to the stator 7. Thus, it undergoes no deformation in case of support of the member 10 on the lever 34 because no radial stress is exerted on the arm 58.

Le bras 58 est conformé de manière à pouvoir se déplacer vers sa position de mémorisation même lorsque le levier 34 est bloqué par la barrette 24 et la butée 40. Le bras 58 peut ainsi toujours se déplacer pour mémoriser l'ordre de déverrouillage indépendamment du fait que le levier 34 soit immobilisé ou pas.The arm 58 is shaped so as to be able to move towards its storage position even when the lever 34 is blocked by the bar 24 and the stop 40. The arm 58 can thus always move to memorize the unlocking order independently of the fact that the lever 34 is immobilized or not.

Le bras 58 est identique par exemple à celui décrit dans la demande de brevet EP 11175117 .The arm 58 is identical for example to that described in the patent application EP 11175117 .

Le mécanisme 9 comporte également un deuxième moyen de rappel 62 (schématisé sur la figure 3), sollicitant le levier 34 vers sa position de déverrouillage, lorsque le bras 58 est dans sa position de mémorisation. Le moyen de rappel 62 n'est pas décrit ici. Il peut être constitué d'une lame ressort, comme celle décrite dans la demande de brevet EP 10161789 . Il peut être aussi identique à celui décrit dans la demande de brevet EP 11175117 . Sur la figure 3, le moyen de rappel 62 est schématisé par une boîte interposée entre le levier 34 et le bras 58 sans que cela préjuge un mode de réalisation particulier de ce moyen de rappel.The mechanism 9 also comprises a second biasing means 62 (schematized on the figure 3 ), biasing the lever 34 to its unlocked position, when the arm 58 is in its storage position. The return means 62 is not described here. It may consist of a spring blade, such as that described in the patent application EP 10161789 . It may also be identical to that described in the patent application EP 11175117 . On the figure 3 , the return means 62 is shown schematically by a box interposed between the lever 34 and the arm 58 without prejudging a particular embodiment of this biasing means.

Le mécanisme 9 comporte également un mécanisme 64 d'immobilisation, apte à retenir le bras 58 dans sa position de mémorisation, même après la disparition de l'ordre de déverrouillage électrique. Le mécanisme 64 permet ainsi de mémoriser mécaniquement cet ordre. Le mécanisme 64 n'est pas décrit ici en détail. Sur la figure 3, le mécanisme 64 est schématisé par une boîte associée au bras 58. Des modes de réalisation détaillés de ce mécanisme 64 sont décrits dans les demandes de brevet EP 10161789 et EP 11175117 .The mechanism 9 also comprises an immobilization mechanism 64, able to hold the arm 58 in its storage position, even after the disappearance of the electric unlocking command. The mechanism 64 thus makes it possible to memorize this order mechanically. Mechanism 64 is not described here in detail. On the figure 3 , the mechanism 64 is shown schematically by a box associated with the arm 58. Detailed embodiments of this mechanism 64 are described in the patent applications EP 10161789 and EP 11175117 .

Le fonctionnement de la serrure va maintenant être présenté en référence à la figure 6.The operation of the lock will now be presented with reference to the figure 6 .

Lors d'une étape 70 préliminaire, la serrure est dans un état verrouillé. Dans cet état verrouillé, les logements 20 et 22 sont en vis-à-vis et l'organe 10 est dans sa position de blocage. Le levier 34 est dans sa position de verrouillage et le bras 58 est en position de repos.In a preliminary step, the lock is in a locked state. In this locked state, the housing 20 and 22 are vis-à-vis and the member 10 is in its locking position. The lever 34 is in its locking position and the arm 58 is in the rest position.

Lors d'une étape 72, un utilisateur introduit la clé 5 dans le canal 6 de la serrure. Le circuit 12 lit le code numérique porté par la clé 5 puis le compare à des codes préenregistrés de clés autorisées à déverrouiller la serrure 2.In a step 72, a user enters the key 5 in the channel 6 of the lock. The circuit 12 reads the digital code carried by the key 5 and then compares it with prerecorded codes of keys authorized to unlock the lock 2.

Si ce code numérique ne correspond à aucun des codes préenregistrés, le mécanisme 9 reste dans l'état verrouillé.If this numeric code does not correspond to any of the prerecorded codes, the mechanism 9 remains in the locked state.

Dans l'état verrouillé, lorsque l'utilisateur tente de tourner le rotor 4, l'organe 10 s'enfonce dans le logement 20. L'organe 10 est légèrement déplacé vers le bas et le jeu 42 s'annule. L'organe 10 exerce alors sur le levier 34 une force sollicitant ce levier 34 vers la butée 40, annulant ainsi le jeu 44, et déplace ainsi le premier axe 46 de sa position initiale, la position haute, vers sa position basse. Lorsque les jeux 42 et 44 sont nuls, le levier 34 est immobilisé entre l'organe 10 et la butée 40. Le déplacement de l'organe 10 vers sa position escamotée est ainsi empêché. Le rotor 4 ne peut donc pas tourner et la serrure reste dans l'état verrouillé. Si la clé 5 est retirée ou n'exerce plus de contrainte sur l'organe 10, les jeux 42 et 44 réapparaissent. L'axe 46 retrouve alors sa position initiale, c'est-à-dire, sa position haute, dans laquelle le levier 34 n'est pas en appui sur la butée 40, grâce au ressort 56 qui exerce une force de rappel sur la plaque 48.In the locked state, when the user tries to turn the rotor 4, the member 10 sinks into the housing 20. The member 10 is slightly moved down and the game 42 is canceled. The member 10 then exerts on the lever 34 a force biasing the lever 34 towards the stop 40, thus canceling the clearance 44, and thus moves the first axis 46 from its initial position, the upper position, to its lower position. When the games 42 and 44 are zero, the lever 34 is immobilized between the member 10 and the stop 40. The displacement of the member 10 to its retracted position is thus prevented. The rotor 4 can not rotate and the lock remains in the locked state. If the key 5 is removed or no longer constrains the member 10, the games 42 and 44 reappear. The axis 46 then returns to its initial position, that is to say, its high position, in which the lever 34 is not resting on the stop 40, thanks to the spring 56 which exerts a restoring force on the plate 48.

Si le code numérique porté par la clé correspond à un code autorisé à déverrouiller la serrure 2, un ordre de déverrouillage du mécanisme 9 est généré lors d'une étape 74.If the numerical code carried by the key corresponds to a code authorized to unlock the lock 2, an unlocking command of the mechanism 9 is generated during a step 74.

Lors de cette étape 74, en réponse à l'ordre de déverrouillage, le bras 58 se déplace de sa position de repos vers sa position de mémorisation.During this step 74, in response to the unlocking command, the arm 58 moves from its rest position to its storage position.

Si la rotation du rotor 4 précède l'ordre de déverrouillage électrique, l'organe 10 vient en appui sur le levier 34 ce qui déplace, comme expliqué en référence de l'étape 70, l'axe 46 de sa position haute vers sa position basse. Le levier 34 est alors immobilisé par l'organe 10 au moment où l'ordre de déverrouillage est généré. Dans ces conditions, le bras 58 mémorise l'ordre en se positionnant dans sa position de mémorisation. Une fois que le levier 34 n'est plus immobilisé, par exemple parce que l'utilisateur replace la clé de manière à ce qu'elle n'exerce plus de force sur l'organe 10, le levier 34 est automatiquement sollicité vers sa position de déverrouillage par le moyen de rappel 62. Le mécanisme 9 est alors déverrouillé.If the rotation of the rotor 4 precedes the electrical unlocking order, the member 10 bears on the lever 34 which moves, as explained with reference to step 70, the axis 46 from its upper position to its position low. The lever 34 is then immobilized by the member 10 at the moment when the unlocking command is generated. Under these conditions, the arm 58 stores the order by positioning itself in its storage position. Once the lever 34 is no longer immobilized, for example because the user places the key so that it no longer exerts force on the member 10, the lever 34 is automatically biased towards its position unlocking by the return means 62. The mechanism 9 is then unlocked.

Ensuite, lors d'une étape 76, l'utilisateur tourne le rotor 4 dans le stator 7 par l'intermédiaire de la clé 5. La rotation du rotor 4 entraîne le déplacement de l'organe 10 de blocage dans sa position escamotée, l'organe 10 n'étant plus bloqué par le levier 34. La serrure est alors déverrouillée.Then, during a step 76, the user rotates the rotor 4 in the stator 7 via the key 5. The rotation of the rotor 4 causes the displacement member 10 to move in its retracted position. 10 member is no longer blocked by the lever 34. The lock is then unlocked.

Lors d'une étape 78, l'utilisateur retire la clé 5 de la serrure. Pour cela, l'utilisateur repositionne le rotor 4 dans le stator 7 par l'intermédiaire de la clé 5 de manière à ce que les logements 20 et 22 soient en vis-à-vis. L'organe 10 est alors sollicité par le ressort 30 de sa position escamotée vers sa position de blocage. Le bras 58 est ramené de sa position de mémorisation vers sa position de repos par l'intermédiaire du talon 26 qui se déplace avec l'organe 10. Le levier 34 est ramené de sa position de déverrouillage vers sa position de verrouillage. La serrure retourne alors dans l'état verrouillé, donc à l'étape 70.During a step 78, the user removes the key 5 from the lock. For this, the user repositions the rotor 4 in the stator 7 via the key 5 so that the housings 20 and 22 are vis-à-vis. The member 10 is then biased by the spring 30 from its retracted position to its locking position. The arm 58 is returned from its storage position to its rest position via the heel 26 which moves with the member 10. The lever 34 is returned from its unlocking position to its locking position. The lock then returns to the locked state, therefore to step 70.

La figure 7 illustre un mécanisme de verrouillage 90 identique au mécanisme 9 à l'exception du fait que les axes 46 et 60 sont remplacés par un seul et même axe 92 de rotation. Le levier 34 et le bras 58 sont montés en rotation sur cet axe 92. L'axe 92 est déplaçable entre une position haute et une position basse. Ces positions haute et basse ont les mêmes définitions que celles données dans le cas de l'axe 46. Pour se déplacer entre ses positions haute et basse, cet axe 92 comporte une extrémité 93A fixée sans aucun degré de liberté à la plaque 48. L'axe 92 comporte également une extrémité opposée 93B montée à coulissement dans un second rail 94 (figure 8) symétrique du rail 50 par rapport à un plan médian 96 perpendiculaire à l'axe 92. A cet effet, l'extrémité 93B est fixée sans aucun degré de liberté à une plaque 98, identique à la plaque 48. La plaque 98 est déplaçable à coulissement à l'intérieur du rail 94. Ainsi, les deux extrémités de l'axe 92 coulissent simultanément chacune dans un rail lorsque l'axe 92 se déplace entre ses positions haute et basse. Dans ce mode de réalisation, le mécanisme comporte un autre ressort 100 de rappel de l'axe 92 vers sa position haute, symétrique du ressort 56 par rapport au plan 96.The figure 7 illustrates a locking mechanism 90 identical to the mechanism 9 except that the axes 46 and 60 are replaced by one and the same axis 92 of rotation. The lever 34 and the arm 58 are rotatably mounted on this axis 92. The axis 92 is movable between a high position and a low position. These high and low positions have the same definitions as those given in the case of the axis 46. To move between its high and low positions, this axis 92 has an end 93A fixed without any degree of freedom to the plate 48. axle 92 also has an opposite end 93B slidably mounted in a second rail 94 ( figure 8 ) symmetrical of the rail 50 relative to a median plane 96 perpendicular to the axis 92. For this purpose, the end 93B is fixed without any degree of freedom to a plate 98, identical to the plate 48. The plate 98 is movable sliding on the inside of the rail 94. Thus, the two ends of the axis 92 slide simultaneously each in a rail when the axis 92 moves between its high and low positions. In this embodiment, the mechanism comprises another spring 100 for returning the axis 92 to its upper position, symmetrical with the spring 56 with respect to the plane 96.

De nombreux autres modes de réalisation sont possibles. Par exemple, le bras de mémorisation 58 peut être omis. Le mécanisme comporte alors, par exemple, un moteur qui entraîne l'axe 46 ou 92 en rotation. Le levier 34 est fixé sans aucun degré de liberté sur l'axe 46 ou 92. Si le levier 34 est en position de verrouillage lorsqu'arrive l'ordre électrique de déverrouillage, alors, le moteur mémorise la commande de déverrouillage, et entraîne le levier vers sa position de déverrouillage dès qu'il n'est plus coincé entre l'organe 10 et la butée 40.Many other embodiments are possible. For example, the storage arm 58 may be omitted. The mechanism then comprises, for example, a motor which drives the axis 46 or 92 in rotation. The lever 34 is fixed without any degree of freedom on the axis 46 or 92. If the lever 34 is in the locked position when the electric unlocking command arrives, then the motor stores the unlocking command, and causes the lever to its unlocking position as soon as it is no longer wedged between the member 10 and the stop 40.

Les deux axes 46 et 60 peuvent ne pas être dans le prolongement l'un de l'autre, mais seulement parallèles.The two axes 46 and 60 may not be in the extension of one another, but only parallel.

La ou les extrémités du premier axe peuvent ne pas comporter de plaque. Par exemple, l'extrémité du premier axe peut coulisser dans une fente en forme de trou oblong aménagée dans le stator. La fente peut être remplie d'un matériau élastique qui joue le rôle de moyen de rappel sollicitant le premier axe vers sa position haute.The end or ends of the first axis may not include a plate. For example, the end of the first axis can slide in an oblong slot shaped slot in the stator. The slot can be filled with a material elastic which acts as a biasing means biasing the first axis to its upper position.

D'autres formes de rail sont possibles. Par exemple, le rail 50 est remplacé par un profilé dont la section transversale est en forme de « U ». La plaque 48 coulisse alors parallèlement au fond du « U ». Elle est guidée en translation par les barres verticales du « U ».Other forms of rail are possible. For example, the rail 50 is replaced by a profile whose cross section is shaped "U". The plate 48 then slides parallel to the bottom of the "U". It is guided in translation by the vertical bars of the "U".

La plaque 48 peut comporter un palier à l'intérieur duquel l'extrémité 49 de l'axe 46 est montée en rotation. Dans ce cas, le levier 34 est par exemple fixé sans aucun degré de liberté sur l'axe 46 de sorte que le levier 34 et l'axe 46 tournent ensemble.The plate 48 may include a bearing within which the end 49 of the shaft 46 is rotatably mounted. In this case, the lever 34 is for example fixed without any degree of freedom on the axis 46 so that the lever 34 and the axis 46 rotate together.

Le mécanisme 90 peut ne comporter qu'une seule plaque 48 à la première extrémité de l'axe 92. Dans ce cas, la plaque 98 est le ressort 100 sont omis.The mechanism 90 may have only one plate 48 at the first end of the axis 92. In this case, the plate 98 is the spring 100 are omitted.

Les plaques 48 et 98 ne sont pas nécessairement perpendiculaires au premier axe.The plates 48 and 98 are not necessarily perpendicular to the first axis.

Le moyen de rappel sollicitant l'axe 46 ou 92 vers sa position haute peut ne pas être un ressort. Par exemple, il peut être constitué d'aimants.The biasing means biasing the axis 46 or 92 to its upper position may not be a spring. For example, it may be magnets.

Le deuxième moyen de rappel 62 ainsi que le mécanisme 64 d'immobilisation peuvent être différents de ceux décrits dans les antériorités citées.The second return means 62 as well as the immobilization mechanism 64 may be different from those described in the cited prior art.

Les caractéristiques structurelles du levier 34 et du bras de mémorisation 58 peuvent être différentes de celles décrites dans la demande de brevet EP 11175117 , tant que ces caractéristiques permettent d'assurer les mêmes fonctions à ces deux éléments.The structural features of the lever 34 and the storage arm 58 may be different from those described in the patent application. EP 11175117 , as long as these characteristics make it possible to ensure the same functions to these two elements.
