Description

L'invention concerne une serrure électronique destinée à être commandée par une clé comportant des moyens électroniques pour commander le déverrouillage électrique de la serrure.The invention relates to an electronic lock intended to be controlled by a key comprising electronic means for controlling the electric unlocking of the lock.

La demande de brevet FR 2 849 083 décrit une serrure électronique et mécanique comportant :

  • un stator et un rotor monté à 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 mobile déplaçable, en réponse à un ordre de déverrouillage électrique, entre une première position dans laquelle la butée mobile est susceptible d'être coincée par l'organe de blocage pour s'opposer à son déplacement à partir de sa position de blocage et une seconde position dans laquelle l'organe de blocage est libre de quitter sa position de blocage.
The patent application FR 2 849 083 discloses an electronic and mechanical lock comprising:
  • 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 displaceable movable stop, in response to an electrical unlocking command, between a first position in which the movable stop is likely to be jammed by the locking member to oppose its displacement from its blocking position and a second position in which the locking member is free to leave its locking position.

Dans la demande de brevet FR 2 849 083 , si la bonne clé est introduite dans le canal de clé puis tournée, alors une force s'exerce sur l'organe de blocage pour le repousser vers sa position escamotée. Toutefois, si l'utilisateur essaie de tourner sa clé dans la serrure avant la vérification que le code numérique de sa clé est le bon, alors une force s'exerce sur l'organe de blocage pour le repousser vers sa position escamotée alors qu'aucun ordre de déverrouillage électrique n'a encore été généré. Dans ces conditions, la butée mobile vient empêcher le déplacement de l'organe de blocage pour le maintenir dans sa position de blocage. Plus précisément, l'organe de blocage vient en contact sur la butée mobile, ce qui empêche son déplacement vers sa position escamotée. Lorsque l'organe de blocage est en appui direct sur la butée mobile, les forces de frottement entre l'organe de blocage et la butée mobile coincent la butée mobile. Lorsque la butée mobile est coincée, elle ne peut plus tourner de sa première position vers sa seconde position. Dès lors, si l'ordre de déverrouillage arrive alors que la butée mobile est coincée, la butée mobile ne peut pas être déplacée vers sa seconde position. Il faut donc maintenir l'ordre de déverrouillage pendant un temps assez long ou le répéter à intervalles réguliers jusqu'à ce que la butée mobile soit décoincée. Ceci entraîne une consommation excessive d'énergie électrique. De l'état de la technique est également connu de US 2002/189 307 A1 .In the patent application FR 2 849 083 if the correct key is inserted into the key channel and turned, then a force is exerted on the locking member to push it back to its retracted position. However, if the user tries to turn his key in the lock before checking that the numerical code of his key is correct, then a force is exerted on the locking member to push it back to its retracted position while no electric unlocking order has yet been generated. Under these conditions, the movable stop prevents the displacement of the locking member to maintain it in its locking position. More specifically, the locking member comes into contact with the movable stop, which prevents its movement towards its retracted position. When the locking member is in direct abutment on the movable stop, the friction forces between the locking member and the movable stop wedge the movable stop. When the movable stop is stuck, it can no longer rotate from its first position to its second position. Therefore, if the unlock command arrives while the movable stop is jammed, the movable stop can not be moved to its second position. It is therefore necessary to maintain the unlocking command for a long time or repeat it at regular intervals until the movable stop is decoupled. This leads to excessive consumption of electrical energy. From the state of the art is also known from US 2002/189307 A1 .

L'invention vise à remédier à cet inconvénient en proposant une serrure électronique dans laquelle la consommation d'énergie électrique est réduite.The invention aims to remedy this drawback by proposing an electronic lock in which the consumption of electrical energy is reduced.

Elle a donc pour objet une serrure électronique conforme à la revendication 1.It therefore relates to an electronic lock according to claim 1.

Dans la serrure ci-dessus, en réponse à l'ordre de déverrouillage électrique, le bras de rappel est déplacé vers sa position de rappel. Ce déplacement est systématiquement possible puisque le bras peut se déplacer de sa position de repos à sa position de rappel même si la butée mobile est coincée. Ensuite, le mécanisme d'immobilisation permet de retenir le bras de rappel dans sa position de rappel sans consommation d'énergie. Ainsi, si la butée mobile est coincée, on stocke une quantité suffisante d'énergie potentielle pour déplacer la butée mobile vers sa seconde position. Dès que la butée mobile est décoincée, elle est donc sollicitée vers sa seconde position par le moyen de rappel qui a stocké l'énergie potentielle. Ainsi, si la butée mobile est coincée, l'ordre de déverrouillage est mémorisé mécaniquement après sa disparition sans consommation d'énergie. On économise donc de l'énergie électrique puisqu'il n'est pas nécessaire de maintenir ou de répéter l'ordre de déverrouillage électrique jusqu'à ce que la butée mobile soit décoincée.In the lock above, in response to the electrical unlock command, the return arm is moved to its return position. This movement is systematically possible since the arm can move from its rest position to its return position even if the movable stop is stuck. Then, the immobilization mechanism allows to retain the return arm in its return position without energy consumption. Thus, if the movable stop is stuck, a sufficient amount of potential energy is stored to move the movable stop to its second position. As soon as the movable stop is disconnected, it is therefore biased towards its second position by the return means which stored the potential energy. Thus, if the movable stop is jammed, the unlocking order is memorized mechanically after its disappearance without energy consumption. Thus, electrical energy is saved since it is not necessary to maintain or repeat the electrical unlocking order until the movable stop is decoupled.

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 1 d'une serrure à double barillet dont l'autre barillet n'est pas montré dans la figure 1. Ce barillet s'étend en profondeur le long d'une direction horizontale Z et verticalement le long d'une direction Y.The figure 1 represents a barrel 1 of a double barrel lock whose other barrel is not shown in the figure 1 . This barrel extends in depth along a horizontal direction Z and vertically along a Y direction.

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 2 qui présente en son milieu un renflement 3 servant d'entretoise pour maintenir un écartement prédéfini entre les deux barillets.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 each other by a connecting rod 2 which has in its middle a bulge 3 serving as a spacer to maintain a predefined spacing between the two barrels.

Le barillet 1 est le barillet côté extérieur de la porte et sa face d'extrémité est généralement disposée à fleur de la face extérieure de la porte, tandis que l'autre barillet est le barillet côté intérieur de la porte et sa face d'extrémité la plus éloignée du barillet 1 est aussi généralement disposée à fleur de la face intérieure de la porte. Le barillet côté intérieur peut être identique au barillet 1 ou il peut en comporter tous les éléments à l'exception des éléments permettant un déverrouillage électrique qui sont décrits en détail plus loin.Barrel 1 is the barrel on the outside of the door and its end face is generally flush with the outer face of the door, while the other barrel is the barrel on the inside of the door and its end face farthest from the barrel 1 is also generally disposed flush with the inner face of the door. The barrel on the inner side may be identical to the barrel 1 or it may include all the elements except the elements allowing an electric unlocking which are described in detail below.

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 montrée en coupe dans les figures 2a à 2d, est introduite dans un canal 6 du rotor 4 et tournée manuellement par un utilisateur. 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. L'axe de rotation du rotor 4 est parallèle à la direction Z.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 shown in section in the Figures 2a to 2d , is introduced into a channel 6 of the rotor 4 and manually rotated by a user. 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 in the direction of rotation of the key 5. The axis of rotation of the rotor 4 is parallel to the direction Z.

En se reportant aux figures 1 et 2a-2d, on peut voir que le rotor 4 du barillet 1 est monté à rotation dans un stator profilé 7, qui a par exemple le profil "européen". Le stator 7 est lui-même logé dans un fourreau extérieur 8 ayant le même profil.Referring to Figures 1 and 2a-2d it can be seen that the rotor 4 of the barrel 1 is rotatably mounted in a profiled stator 7, which for example has the "European" profile. The stator 7 is itself housed in an outer sheath 8 having the same profile.

Le barillet 1 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. Etant 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 1 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. Since this 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 en gros 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 et le stator. Dans ces conditions, le rotor 4 peut être tourné manuellement à l'aide de la clé 5, sous réserve que le dispositif de verrouillage électrique soit lui-même dans un état déverrouillé.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 The associated stator is located exactly at the interface between the rotor and the stator. Under these conditions, the rotor 4 can be rotated manually using the key 5, provided that the electric locking device is itself in an unlocked state.

En effet, le barillet 1 comporte un organe supplémentaire de blocage 15 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 16 (figure 1) qui est logé dans le barillet 1. Le circuit 16, lorsqu'il reçoit un code approprié, génère un ordre de déverrouillage électrique. Par exemple, il commande un actionneur électrique 17 de façon à permettre le déblocage du rotor 4. Ici, le circuit 16 et l'actionneur électrique 17 sont symbolisés par des rectangles (figure 1). L'actionneur 17 est fixé au stator 7 sans aucun degré de liberté.Indeed, the barrel 1 comprises an additional locking member 15 for preventing the rotor 4 from rotating as a suitable digital code contained in a memory (not shown) housed in the key 5 has not been introduced into a circuit electronic 16 ( figure 1 ) which is housed in the cylinder 1. The circuit 16, when it receives an appropriate code, generates an electric unlocking command. For example, it controls an electric actuator 17 so as to enable the unlocking of the rotor 4. Here, the circuit 16 and the electric actuator 17 are symbolized by rectangles ( figure 1 ). The actuator 17 is fixed to the stator 7 without any degree of freedom.

Par exemple, le code est transmis de la clé au circuit électronique 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 16 est équipé d'un lecteur de transpondeurs.For example, the code is transmitted from the key to the electronic circuit of the lock via radio or via electrical contacts. For transmission by radio, preferably, the key 5 is equipped with a transponder and the circuit 16 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 16. Par exemple, le circuit 16 compare alors le code transmis à au moins un code préenregistré dans une mémoire. En cas de concordance des deux codes, le circuit 16 génère l'ordre de déverrouillage électrique de la serrure.When the key 5 is introduced into the channel 6 of the rotor 4, the digital code contained in the memory of the key 5 is transmitted to the circuit 16. For example, the circuit 16 then compares the transmitted code with at least one pre-recorded code in a memory. In case of agreement between the two codes, the circuit 16 generates the electric unlocking order of the lock.

Dans la forme de réalisation de la serrure représentée sur les dessins, l'organe supplémentaire de blocage 15 est une goupille de stator qui coopère avec une goupille 11 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 15 est prolongé par un téton conique 15a, à sommet arrondi, qui est engagé dans un évidement tronconique correspondant 18 formé dans la goupille de rotor 11.In the embodiment of the lock shown in the drawings, the additional locking member 15 is a stator pin which cooperates with a corresponding rotor pin 11 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 15 is extended by a conical stud 15a, with rounded apex, which is engaged in a corresponding frustoconical recess 18 formed in the rotor pin 11.

L'organe 15 est monté coulissant dans un logement cylindrique 12 qui est formé dans le stator 7 et qui est aligné axialement avec un logement 13 dans le rotor 4 dans lequel coulisse la goupille 11 de rotor.The member 15 is slidably mounted in a cylindrical housing 12 which is formed in the stator 7 and which is aligned axially with a housing 13 in the rotor 4 in which slides the pin 11 rotor.

Comme on peut le voir dans les figures 1 et 2a, le stator 7 comporte une cavité 22 en dessous du logement 12. Dans la cavité 22 est disposée une butée mobile 23 qui est montée libre en rotation sur un arbre 17a de façon à pouvoir être tournée d'un quart de tour par l'actionneur électrique 17 en réponse à l'ordre de déverrouillage électrique.As can be seen in the Figures 1 and 2a , the stator 7 comprises a cavity 22 below the housing 12. In the cavity 22 is disposed a movable stop 23 which is rotatably mounted on a shaft 17a so as to be rotated a quarter turn by the actuator 17 in response to the electrical unlock command.

La butée 23 est placée en dessous de l'organe de blocage 15. Plus précisément, la butée 23 est placée en dessous d'une barrette transversale 26 qui est formée d'un seul tenant avec l'organe 15, à l'extrémité inférieure de celui-ci. Les deux extrémités de la barrette 26 sont engagées et guidées dans des fentes 27 (figure 2a) formées dans la paroi du logement 12. Ces fentes 27 empêchent l'organe de blocage 15 de tourner quand il se déplace dans le logement cylindrique 12.The abutment 23 is placed below the locking member 15. More specifically, the abutment 23 is placed below a transverse bar 26 which is formed in one piece with the member 15 at the lower end. of it. Both ends of the bar 26 are engaged and guided in slots 27 ( figure 2a ) formed in the wall of the housing 12. These slots 27 prevent the locking member 15 from rotating when it moves in the cylindrical housing 12.

Un ressort 14 s'appuie, à son extrémité inférieure, contre le fond de la cavité 22 et, à son extrémité supérieure, contre le dessous d'un talon 28 formé à une des deux extrémités de la barrette 26.A spring 14 bears, at its lower end, against the bottom of the cavity 22 and, at its upper end, against the underside of a heel 28 formed at one of the two ends of the bar 26.

La butée mobile 23 a sensiblement la forme d'une palette, dont la section par un plan perpendiculaire à l'arbre 17a a une forme oblongue centrée sur cet arbre 17a.The movable stop 23 has substantially the shape of a pallet, the section of which by a plane perpendicular to the shaft 17a has an oblong shape centered on this shaft 17a.

Quand aucune clé ne se trouve dans le canal 6 du rotor 4 et que ce dernier est dans un état bloqué par les goupilles de stator, la butée 23 occupe une position verticale montrée dans la figure 2a.When no key is in the channel 6 of the rotor 4 and the latter is in a state blocked by the stator pins, the stop 23 occupies a vertical position shown in FIG. figure 2a .

Quand une clé 5 est introduite dans le canal 6 du rotor 4, toutes les goupilles du rotor sont repoussées à l'intérieur de leurs logements respectifs et repoussent elles-mêmes les goupilles de stator associées dans leurs logements respectifs. Dans ces conditions, si la bonne clé a été introduite, les goupilles de stator ne bloquent plus le rotor 4 (figure 2b).When a key 5 is inserted into the channel 6 of the rotor 4, all the pins of the rotor are pushed back inside their respective housings and push themselves the associated stator pins in their respective housings. Under these conditions, if the correct key has been inserted, the stator pins no longer block the rotor 4 ( figure 2b ).

Cependant, le rotor 4 reste bloqué par l'organe de blocage 15 qui est dans sa position de blocage. En effet, le téton conique 15a de l'organe 15 fait encore saillie, à l'intérieur de l'alésage du stator 7, d'une quantité correspondant à la profondeur de l'évidement 18. L'extrémité inférieure de l'organe de blocage 15, plus précisément la barrette 26, se trouve alors à proximité immédiate, c'est-à-dire presque en contact, avec la butée mobile 23 (voir figure 2b).However, the rotor 4 remains blocked by the locking member 15 which is in its locking position. Indeed, the taper 15a of the member 15 is still projecting, within the bore of the stator 7, an amount corresponding to the depth of the recess 18. The lower end of the organ 15, more precisely the bar 26, is then in close proximity, that is to say, almost in contact with the movable stop 23 (see figure 2b ).

Dès que le circuit électronique 16 du barillet a vérifié que la clé 5 porte le bon code numérique, il envoie à l'actionneur électrique 17 l'ordre de déverrouillage électrique. En réponse, l'actionneur 17 fait tourner la butée mobile 23 d'un quart de tour dans le sens des aiguilles d'une montre de façon à amener la butée 23 dans une position horizontale (figure 2c).As soon as the electronic circuit 16 of the cylinder has verified that the key 5 has the correct numerical code, it sends the electric actuator 17 the electric unlocking command. In response, the actuator 17 rotates the movable stop 23 a quarter turn in a clockwise direction so as to bring the stop 23 into a horizontal position ( Figure 2c ).

Dans ces conditions, quand la butée mobile 23 a été amenée dans la position horizontale et quand le rotor 4 commence à tourner sous l'action du couple qui lui est communiqué par la clé 5 actionnée manuellement par un utilisateur, le rotor 4 agit, par l'intermédiaire du bord de l'évidement 18 et de la goupille du rotor 11, sur le téton conique 15a de l'organe de blocage 15 de façon à repousser ce dernier à l'intérieur du logement 12 contre la force de rappel du ressort 14. L'organe 15 atteint ainsi une position escamotée dans laquelle le rotor 4 peut être tourné (figure 2d). Dans la face inférieure de la barrette 26 est prévu un évidement 26a (figures 2c et 2d) dimensionné pour recevoir la butée 23 quand elle est dans sa position horizontale. En conséquence, le rotor 4 peut être tourné et fait fonctionner, par l'intermédiaire d'un panneton, le mécanisme de la serrure qui commande le ou les pênes de celle-ci dans le sens du déverrouillage ou du verrouillage de la serrure selon le sens de rotation de la clé 5 et du rotor 4.Under these conditions, when the movable stop 23 has been brought into the horizontal position and when the rotor 4 starts to rotate under the action of the torque communicated to it by the key 5 manually actuated by a user, the rotor 4 acts by through the edge of the recess 18 and the pin of the rotor 11, on the conical stud 15a of the locking member 15 so as to push the latter inside the housing 12 against the return force of the spring 14. The member 15 thus reaches a retracted position in which the rotor 4 can be rotated ( figure 2d ). In the lower face of the bar 26 is provided a recess 26a ( Figures 2c and 2d ) sized to receive the stop 23 when in its horizontal position. Consequently, the rotor 4 can be rotated and operates, by means of a bit, the mechanism of the lock which controls the bolt or bolts thereof in the direction of unlocking or locking the lock according to the direction of rotation of key 5 and rotor 4.

Après avoir fait tourner la clé 5 et le rotor 4 de un ou plusieurs tours dans le sens voulu pour obtenir le déverrouillage ou le verrouillage de la serrure, chaque goupille de rotor se retrouve en face de la goupille de stator associée. Le téton 15a de l'organe de blocage 15 est alors repoussé par le ressort 14 dans l'évidement 18 de la goupille de rotor 11. La clé 5 peut alors être retirée du canal 6. Il en résulte que le ressort associé à chaque goupille de stator repousse la goupille de rotor associée vers l'intérieur du canal 6. La serrure revient alors dans sa position de blocage montrée dans les figures 1 et 2a.After turning the key 5 and the rotor 4 one or more turns in the desired direction to obtain unlocking or locking the lock, each rotor pin is found opposite the associated stator pin. The pin 15a of the locking member 15 is then pushed by the spring 14 into the recess 18 of the rotor pin 11. The key 5 can then be removed from the channel 6. As a result, the spring associated with each pin the stator pushes the associated rotor pin towards the inside of the channel 6. The lock then returns to its locked position shown in FIGS. Figures 1 and 2a .

Il convient également de ramener la butée 23 dans sa position verticale représentée sur les figures 2a et 2b.It is also necessary to return the abutment 23 to its vertical position represented on the Figures 2a and 2b .

A cet effet, le talon 28 de la barrette 26 comporte un doigt 32 qui s'étend juste au-dessous de la partie droite de la butée 23 quand l'organe de blocage 15 occupe sa position de blocage (figure 2c). Le doigt 32 forme, en combinaison avec le ressort 14, un moyen élastique de rappel pour ramener la butée mobile 23 dans sa position verticale (figures 2a et 2b). En effet, lorsque le ressort 14 repousse vers le haut le talon 18 en réponse à l'enlèvement de la clé 5, le doigt 32 agit sur la butée mobile 23 pour la faire tourner d'un quart de tour dans le sens inverse des aiguilles d'une montre jusque dans sa position verticale (figure 2a).For this purpose, the heel 28 of the bar 26 comprises a finger 32 which extends just below the right part of the abutment 23 when the locking member 15 occupies its locking position ( Figure 2c ). The finger 32 forms, in combination with the spring 14, an elastic return means for returning the movable stop 23 to its vertical position ( Figures 2a and 2b ). Indeed, when the spring 14 pushes up the heel 18 in response to the removal of the key 5, the finger 32 acts on the movable stop 23 to rotate a quarter of a turn in the opposite direction of the needles a watch in its vertical position ( figure 2a ).

D'un autre côté, si la clé 5 introduite dans le canal 6 du rotor 4 ne contient aucun code numérique ou si elle contient un code ne correspondant pas à celui qui est enregistré dans la mémoire du circuit 16, l'actionneur 17 n'est pas excité et la butée mobile 23 reste dans sa position verticale (figure 2b). Il en résulte que si l'on tente de faire tourner le rotor 4 au moyen de la clé, la face inférieure de la barrette 26 vient immédiatement en contact avec la butée 23 qui s'appuie elle-même contre la face supérieure d'une clavette 30 fixée sans aucun degré de liberté au stator 7. Ainsi, l'organe de blocage 15 ne peut pas être déplacé vers le bas d'une quantité suffisante pour que son téton conique 15a sorte de l'évidement 18 de la goupille de stator 11.On the other hand, if the key 5 inserted into the channel 6 of the rotor 4 does not contain any numerical code or if it contains a code which does not correspond to that which is recorded in the memory of the circuit 16, the actuator 17 does not contain any digital code. is not excited and the movable stop 23 remains in its vertical position ( figure 2b ). As a result, if one tries to rotate the rotor 4 by means of the key, the lower face of the bar 26 comes into immediate contact with the stop 23 which itself bears against the upper face of a key 30 fixed without any degree of freedom to the stator 7. Thus, the locking member 15 can not be moved down by an amount sufficient for its conical stud 15a to come out of the recess 18 of the stator pin 11.

Dans l'état de fonctionnement représenté sur la figure 2b, si la clé 5 est tournée avant que l'ordre de déverrouillage électrique ne soit généré, alors la butée 23 est coincée en rotation entre la barrette 26 et la clavette 30. Si l'ordre de déverrouillage arrive alors que la butée 23 est coincée, celui-ci ne peut pas être exécuté immédiatement. Il faut donc mémoriser, sans consommer d'énergie électrique, cet ordre de déverrouillage électrique jusqu'à ce qu'il puisse être exécuté.In the operating state represented on the figure 2b if the key 5 is turned before the electric unlocking command is generated, then the stop 23 is wedged in rotation between the bar 26 and the key 30. If the unlocking command arrives while the stop 23 is stuck it can not be executed immediately. It is therefore necessary to memorize, without consuming electrical energy, this electrical unlocking command until it can be executed.

Les figures 3 à 9 représentent un mécanisme 40 de mémorisation mécanique d'un ordre de déverrouillage électrique implémenté dans le barillet 1. Sur ces figures, les pièces déjà décrites en regard des figures précédentes portent les mêmes références et sont uniquement représentées sous forme schématique.The Figures 3 to 9 represent a mechanism 40 for mechanical storage of an electrical unlocking order implemented in the cylinder 1. In these figures, the parts already described with reference to the preceding figures have the same references and are only shown in schematic form.

La butée 23 est montée libre en rotation autour de l'arbre 17a. A cet effet, elle est équipée d'un moyeu 42 comportant une couche 44 en matériau élastomère propre à absorber des contraintes radiales exercées sur la butée 23 perpendiculairement à l'arbre 17a de manière à ne pas déformer de façon irréversible l'arbre 17a. La couche 44 s'étend principalement le long de la direction de la contrainte susceptible de s'exercer sur la butée 23. Ici, cette direction est confondue avec la direction verticale. Par exemple, la section transversale de la couche 44 dans un plan perpendiculaire à l'arbre 17a définit une ellipse dont le plus grand axe est aligné sur la verticale dans la position représentée sur la figure 3.The stop 23 is rotatably mounted around the shaft 17a. For this purpose, it is equipped with a hub 42 comprising a layer 44 of elastomeric material capable of absorbing radial stresses exerted on the abutment 23 perpendicularly to the shaft 17a so as not to irreversibly deform the shaft 17a. The layer 44 extends mainly along the direction of the stress likely to be exerted on the abutment 23. Here, this direction is coincident with the vertical direction. For example, the cross section of the layer 44 in a plane perpendicular to the shaft 17a defines an ellipse whose largest axis is vertically aligned in the position shown in FIG. figure 3 .

La position représentée sur la figure 3 est la position correspondant à l'état illustré sur la figure 2b, c'est-à-dire un état dans lequel la clé 5 comportant le bon codage mécanique a été introduite dans le canal 6 mais où l'ordre de déverrouillage électrique n'a pas encore été transmis.The position represented on the figure 3 is the position corresponding to the state shown on the figure 2b that is to say a state in which the key 5 having the correct mechanical coding has been introduced into the channel 6 but where the electrical unlocking command has not yet been transmitted.

La serrure comprend une butée 46 fixé au stator 7 sans aucun degré de liberté. Cette butée 46 définit les limites de la course de la butée 23 entre sa position verticale et sa position horizontale.The lock comprises a stop 46 fixed to the stator 7 without any degree of freedom. This stop 46 defines the limits of the stroke of the abutment 23 between its vertical position and its horizontal position.

Un bras de rappel 48 est également monté libre en rotation autour de l'arbre 17a. Ce bras de rappel 48 est mécaniquement raccordé à la butée 23 par l'intermédiaire d'un moyen de rappel. Ici, ce moyen de rappel est réalisé à l'aide de moyens élastiquement déformables. Par exemple, il s'agit d'une lame ressort 50 dont une extrémité est raccordée à une extrémité inférieure de la butée 23 et l'autre extrémité est raccordée à une extrémité supérieure du bras 48. Ce bras 48 est déplaçable, comme la butée 23, entre une position verticale représentée sur les figures 3 à 5 et une position horizontale représentée sur les figures 7 à 9.A return arm 48 is also rotatably mounted around the shaft 17a. This return arm 48 is mechanically connected to the abutment 23 via a return means. Here, this return means is made using elastically deformable means. For example, it is a spring blade 50 whose one end is connected to a lower end of the abutment 23 and the other end is connected to an upper end of the arm 48. This arm 48 is movable, as the stop 23, between a vertical position represented on the Figures 3 to 5 and a horizontal position shown on the Figures 7 to 9 .

La lame ressort 50 est dimensionnée de manière à permettre un déplacement du bras 48 de sa position verticale vers sa position horizontale même si la butée 23 est coincée dans sa position verticale.The leaf spring 50 is dimensioned so as to allow movement of the arm 48 from its vertical position to its horizontal position even if the stop 23 is stuck in its vertical position.

La lame ressort 50 est également conformée pour maintenir la butée 23 dans sa position verticale lorsque le bras 48 est lui-même maintenu sans aucun degré de liberté dans cette position. De préférence, dans la position verticale du bras 48, la lame ressort 50 est en appui sur une butée qui la rigidifie de manière à maintenir fermement la butée 23 dans cette position verticale même si des secousses sont appliquées à la serrure lorsqu'elle est dans l'état représenté sur la figure 2b. Ces secousses sont par exemple celles provoquées par une être humain qui tape directement avec ces mains ou ses pieds sur la porte contenant la serrure. Cette butée est ici constituée par le moyeu 42 qui fait sailli au-delà de la butée 23 dans la direction Z.The spring blade 50 is also shaped to maintain the stop 23 in its vertical position when the arm 48 is itself maintained without any degree of freedom in this position. Preferably, in the vertical position of the arm 48, the spring blade 50 bears against an abutment which stiffens it so as to firmly hold the abutment 23 in this vertical position even if shaking is applied to the lock when it is in position. the state represented on the figure 2b . These jolts are for example those caused by a human being who taps directly with these hands or his feet on the door containing the lock. This stop is here constituted by the hub 42 which protrudes beyond the abutment 23 in the direction Z.

L'extrémité supérieure du bras 48 est une partie aimantée. A cet effet, l'extrémité supérieure est équipée d'un aimant permanent 52 attiré par un aimant permanent 54 fixé sans aucun degré de liberté sur le doigt 32. La force d'attraction qui s'exerce entre les aimants 52 et 54 est notée F1 par la suite.The upper end of the arm 48 is a magnetized part. For this purpose, the upper end is equipped with a permanent magnet 52 attracted by a permanent magnet 54 fixed without any degree of freedom on the finger 32. The attraction force exerted between the magnets 52 and 54 is noted F 1 thereafter.

Les aimants 52 et 54 sont dimensionnés de manière à ce que, lorsque le bras 48 est dans sa position horizontale, la force d'attraction F1 est supérieure à la force de rappel susceptible d'être exercée par la lame ressort 50. Ainsi, le bras 48 peut être maintenu dans sa position horizontale sans consommer d'énergie électrique.The magnets 52 and 54 are dimensioned so that, when the arm 48 is in its horizontal position, the attraction force F 1 is greater than the restoring force that can be exerted by the spring blade 50. Thus, the arm 48 can be maintained in its horizontal position without consuming electrical energy.

L'actionneur électrique 17 est ici un électro-aimant formé d'un bobinage 56 enroulé autour d'un noyau magnétique 58. Le noyau 58 est réalisé dans un matériau susceptible d'attirer un aimant permanent. Par exemple, le noyau 58 est un noyau magnétique doux facilement démagnétisable tel qu'un noyau réalisé dans un alliage de fer ou dans un matériau connu sous le terme anglais de « SuperMalloy ». Un matériau magnétique doux est un matériau magnétique pour lequel l'excitation coercitive de démagnétisation est inférieure à 100 A.m-1. On rappelle que l'excitation coercitive de démagnétisation correspond à l'excitation créée par des courants autour du noyau 58 et permettant de le démagnétiser. A titre de comparaison, l'excitation coercitive d'un aimant permanent est au moins supérieure à 1 000 A.m-1 et de préférence supérieure à 10 000 A.m-1.The electric actuator 17 is here an electromagnet formed of a coil 56 wound around a magnetic core 58. The core 58 is made of a material capable of attracting a permanent magnet. For example, core 58 is a readily demagnetizable soft magnetic core such as a core made of an iron alloy or a material known as "SuperMalloy". A soft magnetic material is a magnetic material for which the coercive demagnetization excitation is less than 100 Am -1 . It is recalled that the coercive excitation of demagnetization corresponds to the excitation created by currents around core 58 and to demagnetize. By way of comparison, the coercive excitation of a permanent magnet is at least greater than 1000 Am -1 and preferably greater than 10,000 Am -1 .

Le noyau 58 présente une face d'extrémité 58a en vis-à-vis de l'extrémité inférieure du bras 48 lorsque celui-ci est dans sa position verticale.The core 58 has an end face 58a opposite the lower end of the arm 48 when the latter is in its upright position.

Cette extrémité inférieure du bras 48 est également une partie aimantée équipée d'un aimant permanent 60. Par exemple, cet aimant 60 est disposé de manière à présenter un pôle sud en face de la face 58a lorsque le bras 48 est dans sa position verticale. Cet aimant 60 est attiré par le noyau 58 lorsque aucun courant ne circule dans le bobinage 56. La force d'attraction entre l'aimant 60 et le noyau 58 est notée F2. Cette force d'attraction peut être ajustée en réglant l'épaisseur d'un entrefer E2 incompressible qui sépare la face 58a du pôle sud de l'aimant 60. L'épaisseur de l'entrefer E2 est fonction de la position de la butée fixe 46.This lower end of the arm 48 is also a magnetized part equipped with a permanent magnet 60. For example, this magnet 60 is arranged to have a south pole in front of the face 58a when the arm 48 is in its vertical position. This magnet 60 is attracted by the core 58 when no current flows in the coil 56. The attraction force between the magnet 60 and the core 58 is noted F 2 . This attraction force can be adjusted by adjusting the thickness of an incompressible air gap E 2 which separates the face 58a from the south pole of the magnet 60. The thickness of the gap E 2 depends on the position of the fixed stop 46.

La butée 23 et le bras 48 s'étendent le long d'axes respectifs 62 et 64 solidaires de ces pièces.The abutment 23 and the arm 48 extend along respective axes 62 and 64 integral with these parts.

Si la bonne clé 5 a été introduite dans le canal 6, l'organe de blocage descend à l'encontre de la force exercée par le ressort 14. Tant que la clé 5 n'est pas tournée, la butée 23 est dimensionnée de manière à ce qu'il existe un jeu J1 et un jeu J2 qui la séparent, respectivement, de la barrette 26 et de la clavette 30 (figure 3). Ces jeux J1 et J2 sont suffisamment larges pour permettre la rotation de la butée 23 de sa position verticale vers sa position horizontale en réponse à un ordre de déverrouillage électrique. Ainsi, si l'ordre de déverrouillage électrique est reçu avant que l'utilisateur ne tourne sa clé 5 à l'intérieur de la serrure, la butée 23 se déplace vers sa position horizontale sans encombre. Dès que la butée 23 a quitté sa position verticale, son déplacement vers la position horizontale peut être actionné par la barrette 26 qui appuie sur l'extrémité supérieure de la butée.If the correct key 5 has been inserted into the channel 6, the locking member descends against the force exerted by the spring 14. As long as the key 5 is not turned, the stop 23 is dimensioned so that there is a game J1 and a game J2 which separate it, respectively, from the bar 26 and the key 30 ( figure 3 ). These sets J1 and J2 are wide enough to allow rotation of the abutment 23 from its vertical position to its horizontal position in response to an electric unlocking command. Thus, if the electric unlocking command is received before the user turns his key 5 inside the lock, the stop 23 moves to its horizontal position without hindrance. As soon as the stop 23 has left its vertical position, its displacement towards the horizontal position can be actuated by the bar 26 which bears on the upper end of the stop.

Toutefois, si avant que l'ordre de déverrouillage électrique ne soit généré, l'utilisateur tourne sa clé 5 dans la serrure, alors l'organe de blocage 15 s'enfonce vers sa position escamotée et rattrape le jeu J1 (figure 5). La barrette 26 est alors directement en contact sur l'extrémité supérieure de la butée 23 et appuie sur cette extrémité supérieure. Si la force d'appui est suffisante, la couche 44 en matériau élastomère du moyeu 42 se déforme et la butée 23 se déplace en translation vers le bas pour rattraper le jeu J2 (figure 5). Dès lors, tant que l'utilisateur force pour tourner sa clé à l'intérieur de la serrure, la butée 23 est coincée en rotation.However, if before the electric unlocking command is generated, the user turns his key 5 in the lock, then the locking member 15 sinks to its retracted position and catches the game J1 ( figure 5 ). The bar 26 is then directly in contact on the upper end of the abutment 23 and bears on this upper end. If the bearing force is sufficient, the layer 44 of elastomeric material of the hub 42 is deformed and the stop 23 moves in translation downwards to catch the clearance J2 ( figure 5 ). Therefore, as the user forces to turn his key inside the lock, the stop 23 is stuck in rotation.

On suppose maintenant que l'ordre de déverrouillage électrique est généré alors que la butée 23 est coincée. En réponse à cet ordre de déverrouillage électrique, le bobinage 56 est alimenté en courant continu de manière à ce qu'un pôle sud apparaisse au niveau de la face 58a. Le pôle sud de l'aimant 60 est donc repoussé, ce qui entraîne le bras 48 en rotation vers sa position horizontale (figure 6). La force de répulsion est suffisante pour tordre la lame ressort 50. De plus, le déplacement du bras 48 vers sa position horizontale est facilité par la force d'attraction F1 qui existe entre les aimants 52 et 54.It is now assumed that the electric unlocking command is generated while the stop 23 is jammed. In response to this electrical unlocking command, the coil 56 is supplied with direct current so that a south pole appears at the face 58a. The south pole of the magnet 60 is thus pushed back, which causes the arm 48 to rotate towards its horizontal position ( figure 6 ). The repulsion force is sufficient to twist the leaf spring 50. In addition, the movement of the arm 48 towards its horizontal position is facilitated by the attraction force F 1 which exists between the magnets 52 and 54.

Après avoir fait un quart de tour, le bras 48 atteint sa position horizontale alors que la butée 23 est toujours coincée dans sa position verticale (figure 7). Dans sa position horizontale, le bras 48 est en appui sur la butée 46. De plus, dans sa position horizontale, le pôle nord de l'aimant 52 est à proximité du pôle sud de l'aimant 54 de sorte que la force d'attraction F1 est supérieure à la force de rappel exercée par la lame ressort 50 pour ramener le bras 48 dans sa position verticale. Cela permet donc de mémoriser mécaniquement l'ordre de déverrouillage électrique. Il n'est donc pas nécessaire de maintenir alimenté le bobinage 56 ou de l'alimenter à intervalles réguliers jusqu'à ce que la butée 23 soit décoincée. Au contraire, l'alimentation du bobinage 56 est dimensionnée de manière à permettre juste le déplacement du bras 48 de sa position verticale à sa position horizontale à l'encontre de la force de rappel de la lame ressort 50. Le bobinage 56 est donc alimenté pendant un très court laps de temps, ce qui minimise sa consommation d'énergie électrique. De plus, en réponse à l'ordre de déverrouillage électrique, le bobinage 56 n'est alimenté qu'une seule fois puisque l'instruction de déverrouillage est ensuite mémorisée mécaniquement par le bras 48.After a quarter turn, the arm 48 reaches its horizontal position while the stop 23 is still stuck in its vertical position ( figure 7 ). In its horizontal position, the arm 48 bears on the abutment 46. In addition, in its horizontal position, the north pole of the magnet 52 is close to the south pole of the magnet 54 so that the force of F 1 attraction is greater than the restoring force exerted by the spring blade 50 to bring the arm 48 in its vertical position. This allows to memorize mechanically the order of electric unlocking. It is therefore not necessary to maintain the power supply coil 56 or to feed it at regular intervals until the stop 23 is decoupled. On the contrary, the supply of the winding 56 is dimensioned so as to allow just the movement of the arm 48 from its vertical position to its horizontal position against the restoring force of the leaf spring 50. The winding 56 is therefore powered for a very short period of time, which minimizes its electrical energy consumption. In addition, in response to the electric unlocking command, the winding 56 is energized only once since the unlocking instruction is then memorized mechanically by the arm 48.

Lorsque l'utilisateur relâche son effort pour faire tourner la clé 5 (voir figure 8), l'organe de blocage remonte sous l'effort du ressort 14 et les jeux J1 et J2 réapparaissent. La butée 23 est donc décoincée et peut de nouveau librement tourner autour de l'arbre 17a.When the user relaxes his effort to turn the key 5 (see figure 8 ), the locking member rises under the force of the spring 14 and games J1 and J2 reappear. The abutment 23 is thus loosened and can again freely rotate around the shaft 17a.

Dès lors, puisque la butée 23 est soumise à la force de rappel exercée par la lame ressort 50, celle-ci se met à tourner de sa position verticale vers sa position horizontale (voir figure 9).Therefore, since the stop 23 is subjected to the restoring force exerted by the leaf spring 50, it starts to rotate from its vertical position to its horizontal position (see figure 9 ).

Le déplacement de la butée 23 vers sa position horizontale peut être facilité par le déplacement de l'organe de blocage 15. En effet, lorsque l'organe 15 descend encore plus sous l'action de la rotation de la clé, la barrette 26 peut venir en appui sur l'extrémité supérieure de la butée 23 pour la rapprocher encore plus de la position horizontale.The displacement of the stop 23 towards its horizontal position can be facilitated by the displacement of the locking member 15. Indeed, when the member 15 descends further under the action of the rotation of the key, the bar 26 can come to bear on the upper end of the abutment 23 to bring it even closer to the horizontal position.

Ainsi, après l'ordre de déverrouillage électrique, dès que la butée 23 est décoincée, l'utilisateur peut tourner sa clé à l'intérieur de la serrure et donc déverrouiller ou verrouiller la porte.Thus, after the electric unlocking command, as soon as the abutment 23 is disconnected, the user can turn his key inside the lock and thus unlock or lock the door.

Après avoir verrouillé ou déverrouillé la serrure, l'utilisateur retire la clé 5 du canal 6. L'organe 15 remonte alors sous l'action du ressort 14. Le doigt 32 repousse alors le bras 48 vers sa position horizontale. L'aimant 60 se rapproche alors du noyau 58. La force d'attraction entre l'aimant 60 et le noyau 58 est suffisante pour ramener et maintenir le bras 48 dans sa position verticale. De plus, le retour du bras 48 dans sa position verticale ramène également la butée 23 dans sa position verticale illustrée sur la figure 3. Dans cette position verticale, la force d'attraction F2 de l'aimant 60 maintient le bras 48 et donc la butée 23 dans la position verticale même en cas de secousses exercées sur la serrure.After locking or unlocking the lock, the user removes the key 5 from the channel 6. The member 15 then rises under the action of the spring 14. The finger 32 then pushes the arm 48 to its horizontal position. The magnet 60 then approaches the core 58. The attractive force between the magnet 60 and the core 58 is sufficient to return and maintain the arm 48 in its vertical position. In addition, the return of the arm 48 in its vertical position also brings the stop 23 back to its vertical position illustrated on the figure 3 . In this vertical position, the attraction force F 2 of the magnet 60 maintains the arm 48 and therefore the abutment 23 in the vertical position even in case of shaking exerted on the lock.

De nombreux autres modes de réalisation sont possibles. Par exemple, les parties aimantées du bras 48 peuvent être réalisées différemment. Par exemple, la figure 10 représente un bras de rappel 48 identique au précédent à l'exception du fait que les aimants 52 et 60 ont respectivement été remplacés par des aimants 72 et 70. L'axe de polarisation des aimants 70 et 72 est parallèle à l'axe 64 et non pas perpendiculaire.Many other embodiments are possible. For example, the magnetized portions of the arm 48 may be made differently. For example, the figure 10 represents a restoring arm 48 identical to the previous one except that the magnets 52 and 60 have respectively been replaced by magnets 72 and 70. The polarization axis of the magnets 70 and 72 is parallel to the axis 64 and not perpendicular.

Dans le mode de réalisation de la figure 11, le bras 48 de rappel est aimanté de sorte que les aimants et le bras 48 ne forment qu'un seul bloc de matière.In the embodiment of the figure 11 , the return arm 48 is magnetized so that the magnets and the arm 48 form a single block of material.

Le bras de rappel peut prendre n'importe quelle forme. Il n'est pas nécessaire que ses déplacements soient similaires à ceux de la butée mobile. Par exemple, si la butée mobile se déplace en rotation, le bras de rappel peut être déplacé en translation et vice versa.The return arm can take any form. It is not necessary that its displacements are similar to those of the mobile stop. For example, if the movable stop moves in rotation, the return arm can be moved in translation and vice versa.

D'autres moyens de rappel qu'une lame ressort sont possibles. Par exemple, la force de rappel peut être créée à l'aide d'aimants permanents de polarité complémentaire disposés, respectivement, sur le bras 48 et la butée 23.Other return means that a spring blade are possible. For example, the restoring force can be created by means of permanent magnets of complementary polarity arranged respectively on the arm 48 and the abutment 23.

En variante, le bras de rappel et/ou la butée mobile font moins d'un quart de tour pour se déplacer entre leurs positions extrêmes respectives.Alternatively, the return arm and / or the movable stop are less than a quarter of a turn to move between their respective end positions.

Par exemple, l'actionneur 17 peut être positionné à d'autres endroits. A titre d'illustration, la figure 12 représente un mécanisme 80 de mémorisation mécanique de l'ordre de déverrouillage électrique pouvant être utilisé en lieu et place du mécanisme 40 précédemment décrit. Ce mécanisme 80 est identique au mécanisme 40 à l'exception du fait que l'aimant 60 est omis et que la face 58a de l'actionneur 17 est disposée en vis-à-vis d'une face 52a de l'aimant 52. Sur la figure 12, la butée 23 et la lame ressort 50 n'ont pas été représentées pour simplifier l'illustration. Typiquement, la face 52a correspond au pôle sud de l'aimant 52. De plus, l'actionneur 17 est disposé à un emplacement qui n'entrave pas la descente de la barrette 26 lorsque le rotor 4 est tourné.For example, the actuator 17 may be positioned at other locations. As an illustration, the figure 12 represents a mechanism 80 for mechanical storage of the electrical unlocking order that can be used in place of the mechanism 40 previously described. This mechanism 80 is identical to the mechanism 40 with the exception that the magnet 60 is omitted and the face 58a of the actuator 17 is disposed opposite a face 52a of the magnet 52. On the figure 12 the abutment 23 and the leaf spring 50 have not been shown to simplify the illustration. Typically, the face 52a corresponds to the south pole of the magnet 52. In addition, the actuator 17 is disposed at a location that does not hinder the descent of the bar 26 when the rotor 4 is rotated.

Ce mode de réalisation présente l'avantage qu'un seul aimant 52 est utilisé au lieu de deux. Cet aimant 52 remplit donc les fonctions suivantes :

  • maintien du bras 48 et de la butée 23 dans la position verticale lorsque la serrure est dans l'état représenté dans la figure 2b,
  • déplacement du bras 48 et de la butée 23 de la position verticale vers la position horizontale lorsque celui-ci est repoussé par l'actionneur 17, et
  • maintien du bras 48 dans sa position horizontale par la force d'attraction F1.
This embodiment has the advantage that only one magnet 52 is used instead of two. This magnet 52 thus fulfills the following functions:
  • maintaining the arm 48 and the abutment 23 in the vertical position when the lock is in the state represented in the figure 2b ,
  • displacement of the arm 48 and the abutment 23 from the vertical position to the horizontal position when the latter is pushed back by the actuator 17, and
  • maintaining the arm 48 in its horizontal position by the force of attraction F 1 .

Les polarités des aimants permanents décrits ici peuvent être inversées. Dans ce cas, le fonctionnement de l'actionneur 17 sera adapté en fonction de la polarité de l'aimant à repousser.The polarities of the permanent magnets described here can be reversed. In this case, the operation of the actuator 17 will be adapted according to the polarity of the magnet to be pushed back.

L'organe de blocage 15 a été décrit dans le cas particulier où il est associé à une goupille de rotor pour être déplacé sous l'action de la rotation de la clé 5. En variante, l'organe de blocage n'est pas associé à une goupille de rotor. Dans ce cas, c'est la rotation du rotor 4 qui sollicite l'organe de blocage vers sa position rétractée.The locking member 15 has been described in the particular case where it is associated with a rotor pin to be moved under the action of the rotation of the key 5. Alternatively, the locking member is not associated to a rotor pin. In this case, it is the rotation of the rotor 4 which urges the locking member towards its retracted position.

La butée 46 peut être omise si le noyau 58 remplit également la fonction de butée pour délimiter la position verticale du bras 48 et si l'extrémité 32a et le doigt 32 sont conformés pour former une butée délimitant la position horizontale du bras 48.The abutment 46 can be omitted if the core 58 also fulfills the stop function to delimit the vertical position of the arm 48 and if the end 32a and the finger 32 are shaped to form a stop defining the horizontal position of the arm 48.

Le noyau 58 peut être réalisé dans un matériau magnétique aimantable ou aimanté.The core 58 may be made of a magnetizable magnetic material or magnetized.

Les goupilles de stator et de rotor non représentées et remplissant la fonction de verrouillage et de déverrouillage mécanique peuvent être omises.The stator and rotor pins not shown and performing the function of locking and mechanical unlocking can be omitted.

L'organe de blocage 15 a été représenté dans le cas particulier où celui-ci se déplace en translation perpendiculairement à l'axe de rotation du rotor. D'autres déplacements sont possibles pour l'organe de blocage tels que par exemple une rotation entre sa position de blocage et sa position escamotée autour d'un axe parallèle à l'axe de rotation du rotor.The locking member 15 has been shown in the particular case where the latter moves in translation perpendicular to the axis of rotation of the rotor. Other displacements are possible for the locking member such as for example a rotation between its locking position and its retracted position about an axis parallel to the axis of rotation of the rotor.

Les emplacements de l'actionneur 17 et de l'aimant 60 peuvent être inversés. Dans ce cas, c'est donc l'actionneur 17 qui se trouve monté sur le bras 48.The locations of the actuator 17 and the magnet 60 can be reversed. In this case, it is therefore the actuator 17 which is mounted on the arm 48.

Le déplacement du bras 48 de sa position verticale vers sa position horizontale peut être actionné par d'autres types d'actionneurs qu'un électro-aimant. Par exemple, le déplacement du bras 48 peut être actionné par un moteur électrique tel que celui décrit dans la demande de brevet FR 2 849 083 .The movement of the arm 48 from its vertical position to its horizontal position can be actuated by other types of actuators than an electromagnet. For example, the movement of the arm 48 can be actuated by an electric motor such as that described in the patent application. FR 2 849 083 .

Il n'est pas nécessaire que le même noyau magnétique soit utilisé par l'électroaimant 17 et par l'aimant permanent 60 ou 52. Par exemple, la fonction de maintien du bras 48 dans sa position verticale ou horizontale peut être remplie à l'aide d'un aimant permanent et d'un noyau magnétique indépendant de l'électroaimant ou à l'aide de deux aimants permanents solidaires, pour l'un, du bras 48 et, pour l'autre, du stator 7.It is not necessary that the same magnetic core be used by the electromagnet 17 and the permanent magnet 60 or 52. For example, the function of holding the arm 48 in its vertical or horizontal position can be filled to the using a permanent magnet and a magnetic core independent of the electromagnet or with the aid of two solid permanent magnets, one for the arm 48 and the other for the stator 7.

L'aimant 54 peut être remplacé par un noyau magnétique.The magnet 54 can be replaced by a magnetic core.
