Description

L'invention concerne une serrure à contrôle par aimants, et plus particulièrement une serrure à contrôle par aimants, comportant un cylindre à stator et rotor solidarisés en l'absence de clé, et comportant une clé à aimants pour le déblocage du rotor. L'invention concerne aussi la clé pour serrure à contrôle par aimants.The invention relates to a lock controlled by magnets, and more particularly to a lock controlled by magnets, comprising a cylinder with stator and rotor secured in the absence of a key, and comprising a key with magnets for unlocking the rotor. The invention also relates to the key for a lock controlled by magnets.

Le document EP 1 482 108 décrit une clé plate à profil cranté, comportant un aimant pour attirer dans l'un des crans du profil, une goupille non sollicitée par ressort.The document EP 1 482 108 describes a flat key with notched profile, comprising a magnet for attracting in one of the notches of the profile, an unsolicited pin by spring.

Le document EP 2 492 421 décrit une clé plate à l'extrémité de laquelle est disposé un aimant plat, apte à écarter, dans le rotor, deux aimants qui s'attirent en maintenant une goupille dans le passage de clé. L'un des deux aimants écartés par la clé est solidaire de la goupille et son déplacement libère le passage de clé. Pour écarter les deux aimants du rotor, la clé n'a qu'un sens d'insertion.The document EP 2 492 421 describes a flat key at the end of which a flat magnet is placed, able to separate, in the rotor, two magnets which attract each other while maintaining a pin in the keyway. One of the two magnets separated by the key is integral with the pin and its movement releases the key passage. To remove the two magnets from the rotor, the key has only one direction of insertion.

Le document EP 0 571 311 décrit une clé plate portant un aimant sur chacune de ses deux faces latérales. Quel que soit le sens d'introduction de la clé, l'un des aimants est en position pour repousser un aimant, logé dans le rotor, et qui à son tour repousse hors du rotor une goupille sollicitée par ressort. La mise en place des aimants sur les faces latérales de la clé est délicate, compte tenu de leur polarité qui impose leur décalage.The document EP 0 571 311 describes a flat key carrying a magnet on each of its two side faces. Regardless of the direction in which the key is inserted, one of the magnets is in position to repel a magnet, housed in the rotor, and which in turn pushes a spring loaded pin out of the rotor. Placing the magnets on the side faces of the key is tricky, given their polarity which imposes their offset.

Les aimants 3, 4 sont logés dans une capsule 5, non magnétique, en matière plastique par exemple, qui présente une gorge annulaire 7 dans l'intervalle entre les aimants 3 et 4 ( Figure 3 ). Les aimants 3, 4 ont de préférence le même axe géométrique. Ils sont par exemple cylindriques, mais peuvent être de forme quelconque.The Figure 1 shows a key rod 1 of rectangular section, comprising near its end a housing 2 receiving magnets 3, 4. The magnets 3, 4 are housed in a capsule 5, non-magnetic, made of plastic for example, which has a annular groove 7 in the interval between magnets 3 and 4 ( Figure 3 ). The magnets 3, 4 preferably have the same geometric axis. They are for example cylindrical, but can be of any shape.

Les faces en regard des aimants 3, 4 sont de même polarité, par exemple Sud (S).The opposite sides of the magnets 3, 4 have the same polarity, for example South (S).

Les autres faces des aimants 3, 4, ou faces extérieures sont aussi de même polarité, par exemple Nord (N).The other faces of the magnets 3, 4, or outer faces are also of the same polarity, for example North (N).

Dans la tige 1 de clé, le logement 2 est un passage cylindrique dans lequel est insérée la capsule 5 contenant les deux aimants 3, 4. Pour maintenir la capsule 5 dans le logement 2, une goupille 6 est introduite dans un passage 8 d'axe perpendiculaire à l'axe du logement 2, et décalé par rapport à l'axe du logement 2, de façon que la goupille 6 coopère avec la gorge annulaire 7 pour assurer le maintien de la capsule 5 dans la tige 1 de la clé. Ce maintien s'analyse comme une retenue, et non pas comme un blocage de la capsule 5 dans le logement 2 ( Figure 4 ), l'ensemble de la capsule 5 et des deux aimants 3, 4 étant doué d'une certaine mobilité dans le logement 2 ( Figure 11 ). In the key rod 1, the housing 2 is a cylindrical passage in which is inserted the capsule 5 containing the two magnets 3, 4. To hold the capsule 5 in the housing 2, a pin 6 is introduced into a passage 8 of axis perpendicular to the axis of the housing 2, and offset from the axis of the housing 2, so that the pin 6 cooperates with the annular groove 7 to ensure the maintenance of the capsule 5 in the shank 1 of the key. This maintenance is analyzed as a retention, and not as a blockage of the capsule 5 in the housing 2 ( Figure 4 ), the whole of the capsule 5 and the two magnets 3, 4 being endowed with a certain mobility in the housing 2 ( Figure 11 ).

La Figure 2 représente une tige 11 de clé ronde, comportant au voisinage de son extrémité un logement 2 cylindrique, d'axe perpendiculaire à l'axe de la tige 11 de clé, apte à recevoir une capsule 5 contenant deux aimants 3, 4 ayant leurs faces en regard de même polarité, S par exemple. La capsule 5 est retenue dans le logement 2 au moyen d'une goupille 6 insérée dans le passage 8 d'axe perpendiculaire à l'axe du logement 2, et décalé par rapport à l'axe du logement 2, la goupille 6 coopérant avec la gorge annulaire 7 de la capsule 5.The Figure 2 shows a round key rod 11, comprising in the vicinity of its end a cylindrical housing 2, of axis perpendicular to the axis of the key rod 11, capable of receiving a capsule 5 containing two magnets 3, 4 having their faces in look of the same polarity, S for example. The capsule 5 is retained in the housing 2 by means of a pin 6 inserted in the passage 8 with an axis perpendicular to the axis of the housing 2, and offset with respect to the axis of the housing 2, the pin 6 cooperating with the annular groove 7 of the capsule 5.

L'axe de la tige 11 de clé et l'axe du logement 2, définissent pour la clé, un plan de référence. Les aimants 3, 4 sont alignés sur l'axe du logement 2. Ce plan de référence est un plan de symétrie pour la tige de clé à l'exception de l'extrémité 9 de la tige de clé qui est de forme polygonale dans l'exemple de réalisation de la Figure 2 . The axis of the key shank 11 and the axis of the housing 2 define a reference plane for the key. The magnets 3, 4 are aligned with the axis of the housing 2. This reference plane is a plane of symmetry for the key shank except for the end 9 of the key shank which is polygonal in shape. example of the Figure 2 .

La tige 11 de clé ronde doit avoir une position bien définie dans le rotor, en fin d'introduction, pour pouvoir assurer son rôle d'entrainement du rotor. Or la tige 11 de clé ronde peut être introduite dans le rotor avec n'importe quelle orientation. Pour assurer la mise en position correcte de fonctionnement de la clé, le rotor 10 porte une goupille fixe 12 d'orientation de la tige 11 de clé ronde ( Figures 9 , 10 ). De son côté, la tige 11 de clé présente un profil de guidage 13, 14 en forme de vague, disposé symétriquement par rapport au plan de référence de la tige 11 de clé.The round key rod 11 must have a well-defined position in the rotor, at the end of the introduction, to be able to perform its role of driving the rotor. Now the round key rod 11 can be introduced into the rotor with any orientation. To ensure the correct positioning of the key, the rotor 10 carries a fixed pin 12 for orienting the rod 11 of the round key ( Figures 9 , 10 ). For its part, the key rod 11 has a wave-shaped guide profile 13, 14, arranged symmetrically with respect to the reference plane of the key rod 11.

Ce profil de guidage est aussi symétrique par rapport au plan perpendiculaire au plan de référence de la tige 11 de clé. Ainsi, quelle que soit l'orientation de la clé lors de son introduction dans la serrure, dès que le profil de guidage 13, 14, touche la goupille d'orientation 12, le glissement du profil de guidage sur la goupille d'orientation assure la rotation de la clé pour qu'en fin de course d'introduction, la clé soit dans la position correcte de fonctionnement. Le profil de guidage étant symétrique par rapport à deux plans perpendiculaires, la rotation de la clé est au maximum d'un quart de tour, et la clé est réversible. La clé n'a pas d'orientation imposée à l'introduction dans le rotor de la serrure.This guide profile is also symmetrical with respect to the plane perpendicular to the reference plane of the shank 11 of the key. Thus, whatever the orientation of the key when it is inserted into the lock, as soon as the guide profile 13, 14 touches the orientation pin 12, the sliding of the guide profile on the orientation pin ensures turning the key so that at the end of the insertion stroke the key is in the correct operating position. The guide profile being symmetrical with respect to two perpendicular planes, the rotation of the key is a maximum of a quarter turn, and the key is reversible. The key has no orientation imposed on introduction into the rotor of the lock.

Le rotor 10 est logé dans un stator ou faux stator 15, auquel il est solidarisé en l'absence de clé ( Figure 5 ). Au voisinage de son extrémité intérieure, et sur un axe perpendiculaire à l'axe longitudinal du rotor, sont disposés, à la partie supérieure un aimant 16 dans un premier logement 18 et à la partie inférieure une goupille 17 dans un deuxième logement 19. L'aimant supérieur 16 est situé dans le premier logement 18 commun au stator 15 et au rotor 10. Ce premier logement 18 ne débouche pas dans l'espace central du rotor 10. De ce fait, l'aimant supérieur 16 repose par gravité sur le fond du premier logement 18. Dans cette position de repos, l'aimant supérieur 16 remplit la partie du premier logement 18 située dans le rotor 10 et partiellement la partie du premier logement 18 située dans le stator 15. Dans cette position de repos, l'aimant supérieur 16 empêche toute rotation du rotor 10 par rapport au stator 15.The rotor 10 is housed in a stator or false stator 15, to which it is secured in the absence of a key ( Figure 5 ). In the vicinity of its inner end, and on an axis perpendicular to the longitudinal axis of the rotor, are arranged, at the upper part a magnet 16 in a first housing 18 and at the lower part a pin 17 in a second housing 19. L the upper magnet 16 is located in the first housing 18 common to the stator 15 and to the rotor 10. This first housing 18 does not open into the central space of the rotor 10. Therefore, the upper magnet 16 rests by gravity on the bottom of the first housing 18. In this rest position, the upper magnet 16 fills the part of the first housing 18 located in the rotor 10 and partially the part of the first housing 18 located in the stator 15. In this rest position, the The upper magnet 16 prevents any rotation of the rotor 10 relative to the stator 15.

Selon une variante de réalisation, l'aimant 16 n'est pas soumis à la seule gravité, mais il est sollicité par un ressort vers le fond du logement 18.According to an alternative embodiment, the magnet 16 is not subjected to gravity alone, but it is urged by a spring towards the bottom of the housing 18.

Cette variante de réalisation permet de disposer le logement 18 avec un axe à orientation différente de la verticale.This variant embodiment makes it possible to have the housing 18 with an axis with an orientation different from the vertical.

La goupille inférieure 17 est située dans un deuxième logement 19 commun au stator 15 et au rotor 10. Ce deuxième logement 19 débouche dans l'espace central du rotor 10, dans l'axe du premier logement 18.The lower pin 17 is located in a second housing 19 common to the stator 15 and to the rotor 10. This second housing 19 opens into the central space of the rotor 10, in the axis of the first housing 18.

Dans le deuxième logement 19 se trouve un empilage classique comportant un ressort 20, coiffé par une enveloppe cylindrique jouant le rôle de goupille de stator 21, et la goupille 17 faisant fonction de goupille de rotor. Lorsque la clé est introduite dans le rotor 10, elle repousse la goupille inférieure 17. Lorsque la clé est en position correcte, la capsule 5 contenant les deux aimants 3 et 4 se trouve en regard de la goupille 17 dont la pointe arrive au contact de l'un des aimants 3, 4. La goupille 17 est alors toute entière dans le rotor et la goupille de stator 21 est alors toute entière dans le stator, et le rotor peut tourner.In the second housing 19 is a conventional stack comprising a spring 20, capped by a cylindrical casing acting as a stator pin 21, and the pin 17 acting as a rotor pin. When the key is introduced into the rotor 10, it pushes back the lower pin 17. When the key is in the correct position, the capsule 5 containing the two magnets 3 and 4 is located opposite the pin 17, the tip of which comes into contact with one of the magnets 3, 4. The pin 17 is then entirely in the rotor and the stator pin 21 is then entirely in the stator, and the rotor can rotate.

Selon le mode de réalisation de la Figure 11 , la capsule 5 contenant les deux aimants 3 et 4 est pourvue, non pas d'une gorge annulaire 7, mais d'une échancrure latérale 27 d'une certaine hauteur, lui assurant un déplacement relatif par rapport à la goupille fixe 6. La capsule 5 est mobile en translation dans l'axe du logement 2. Ainsi, tant que la clé n'est pas dans la serrure, la capsule 5 fait saillie de son logement 2, le bord supérieur de son échancrure 27 étant en appui sur la goupille fixe 6. Pour que la clé puisse être introduite sans difficulté dans la serrure, la capsule 5 présente, de part et d'autre de son échancrure 27, des pans obliques 28 assurant son effacement dans la tige de clé.Depending on the embodiment of the Figure 11 , the capsule 5 containing the two magnets 3 and 4 is provided not with an annular groove 7, but with a lateral notch 27 of a certain height, ensuring it a relative displacement with respect to the fixed pin 6. The capsule 5 is movable in translation in the axis of the housing 2. Thus, as long as the key is not in the lock, the capsule 5 protrudes from its housing 2, the upper edge of its notch 27 resting on the fixed pin 6. So that the key can be inserted without difficulty into the lock, the capsule 5 has, on either side of its notch 27, oblique faces 28 ensuring its removal in the key shank.

Lorsque la clé atteint sa position finale correspondant à la Figure 11 , la capsule est placée sur la goupille inférieure 17 qui la sollicite vers le haut sous l'action de son ressort 20. Pour permettre à la capsule 5 de faire saillie au-dessus de la tige de clé, le rotor 10 est muni d'un évidement sous le logement 18 de l'aimant supérieur 16.When the key reaches its final position corresponding to the Figure 11 , the capsule is placed on the lower pin 17 which biases it upwards under the action of its spring 20. To allow the capsule 5 to protrude above the key shank, the rotor 10 is provided with a recess under the housing 18 of the upper magnet 16.

La goupille inférieure 17 repousse la capsule 5 jusqu'à ce que le bord inférieur de l'échancrure 27 soit en appui sur la goupille fixe 6. L'aimant 3 est alors suffisamment proche de l'aimant supérieur 16 pour le repousser, éventuellement en comprimant son ressort. Dans cette position en appui sur la goupille fixe 6, la capsule 5 assure deux fonctions. D'une part, elle maintient la goupille inférieure 17 entièrement dans le rotor 10, d'autre part, elle maintient l'aimant supérieur 16 entièrement dans le stator 15. Elle contrôle ainsi deux points de sécurité pour autoriser la rotation du rotor.The lower pin 17 pushes the capsule 5 back until the lower edge of the notch 27 rests on the fixed pin 6. The magnet 3 is then sufficiently close to the upper magnet 16 to push it back, possibly by compressing its spring. In this position resting on the fixed pin 6, the capsule 5 performs two functions. On the one hand, it maintains the lower pin 17 entirely in the rotor 10, on the other hand, it maintains the upper magnet 16 entirely in the stator 15. It thus controls two safety points to allow rotation of the rotor.

Près de son ouverture d'accès ( Figure 5 ), le rotor 10 comporte un troisième logement 25 recevant une goupille 22 de solidarisation du rotor 10 et de la tige de clé 1 ou 11. Cette goupille 22 est sollicitée par un ressort 24 et fait saillie dans l'espace central du rotor 10. Le ressort 24, comme le ressort 20 de la goupille inférieure 17, est coiffé par une enveloppe cylindrique constituant une goupille de stator, qui assure le blocage du rotor 10 par rapport au stator 15 en l'absence de clé. La tige de clé 1 ou 11 présente deux échancrures 23 symétriques, chacune pouvant recevoir la goupille 22 dans une position autorisant la rotation du rotor 10 dans le stator 15, et assurant la solidarisation de la clé et du rotor pour assurer cette rotation ( Figure 6 ). Near its access opening ( Figure 5 ), the rotor 10 comprises a third housing 25 receiving a pin 22 for securing the rotor 10 and the rod key 1 or 11. This pin 22 is biased by a spring 24 and projects into the central space of the rotor 10. The spring 24, like the spring 20 of the lower pin 17, is capped by a cylindrical casing constituting a pin stator, which locks the rotor 10 relative to the stator 15 in the absence of a key. The key rod 1 or 11 has two symmetrical notches 23, each capable of receiving the pin 22 in a position allowing the rotation of the rotor 10 in the stator 15, and ensuring the connection of the key and the rotor to ensure this rotation ( Figure 6 ).

De préférence, le rotor 10, entre le troisième logement 25 de la goupille 22 et le premier logement 18 de l'aimant 16, comporte plusieurs logements recevant chacun une goupille, et la tige de clé comporte autant d'échancrures pour recevoir les pointes des goupilles.Preferably, the rotor 10, between the third housing 25 of the pin 22 and the first housing 18 of the magnet 16, comprises several housings each receiving a pin, and the key shank has as many notches to receive the tips of the pins. pins.

A son extrémité intérieure ( Figure 5 ) le rotor 10 présente un logement polygonal 26, par exemple hexagonal, apte à recevoir l'extrémité polygonale 9 d'une clé ronde par exemple ( Figure 7 ). La clé étant réversible, le logement polygonal 26 reçoit aussi l'extrémité polygonale 9 de la clé dans sa position inversée ( Figure 8 ). At its inner end ( Figure 5 ) the rotor 10 has a polygonal housing 26, for example hexagonal, adapted to receive the polygonal end 9 of a round key for example ( Figure 7 ). The key being reversible, the polygonal housing 26 also receives the polygonal end 9 of the key in its inverted position ( Figure 8 ).

Le fonctionnement de la serrure est autorisé lorsque la clé est en position et que les aimants et goupilles sont aussi en position de libération du rotor. Selon l'invention, les deux aimants 3 et 4 de la clé sont montés sur un même axe géométrique, avec leurs faces en regard de même polarité (S par exemple) et leurs faces extérieures de l'autre polarité (N par exemple). Au voisinage de l'extrémité intérieure du rotor 10, l'aimant supérieur 16 a sa face en regard de la tige de clé de la même polarité que les faces extérieures des aimants du rotor (N par exemple).Operation of the lock is authorized when the key is in position and the magnets and pins are also in the rotor release position. According to the invention, the two magnets 3 and 4 of the key are mounted on the same geometric axis, with their facing faces of the same polarity (S for example) and their outer faces of the other polarity (N for example). In the vicinity of the inner end of the rotor 10, the upper magnet 16 has its face facing the key shank of the same polarity as the outer faces of the magnets of the rotor (N for example).

Ainsi, lors de la pénétration de la tige de clé dans le rotor, l'aimant supérieur 16 du cylindre est repoussé par l'un des aimants 3, 4 du rotor et le rotor 10 est désolidarisé du stator 15.Thus, during the penetration of the key shank into the rotor, the upper magnet 16 of the cylinder is pushed back by one of the magnets 3, 4 of the rotor and the rotor 10 is separated from the stator 15.

En l'absence de clé introduite dans le rotor, ou en présence d'une clé non pourvue de la fonction magnétique décrite, ou d'une clé pourvue d'une fonction magnétique non correctement polarisée, ou avec un entrefer non adéquat, l'aimant supérieur 16 n'est pas positionné pour autoriser la libre rotation du rotor et le cylindre reste verrouillé.In the absence of a key inserted in the rotor, or in the presence of a key not provided with the magnetic function described, or of a key provided with a magnetic function not correctly polarized, or with an inadequate air gap, the upper magnet 16 is not positioned to allow free rotation of the rotor and the cylinder remains locked.

Dans la mesure où le plan défini par l'axe du rotor 10 et l'axe de l'aimant supérieur 16 et de la goupille inférieure 17, ou premier plan de référence, est vertical, l'aimant supérieur 16 peut être libre dans son logement 18 et soumis simplement à la gravité.Insofar as the plane defined by the axis of the rotor 10 and the axis of the upper magnet 16 and the lower pin 17, or the first reference plane, is vertical, the upper magnet 16 can be free in its housing 18 and simply subjected to gravity.

Selon un autre mode de réalisation de l'invention, le premier logement 18 reçoit un moyen de blocage du rotor en l'absence de clé qui, au lieu d'être un aimant tel que 16, est une goupille ferromagnétique sollicitée par un ressort vers le stator. Lorsque la clé est introduite, les aimants 3, 4 arrivent en regard de la goupille ferromagnétique et l'attirent en comprimant son ressort, dans une position de libération du rotor.According to another embodiment of the invention, the first housing 18 receives a means for locking the rotor in the absence of a key which, instead of being a magnet such as 16, is a ferromagnetic pin urged by a spring towards the stator. When the key is inserted, the magnets 3, 4 arrive opposite the ferromagnetic pin and attract it by compressing its spring, in a position of release of the rotor.

La goupille 12 d'orientation de la clé ronde assurera la mise en position correcte de la clé par la mise en coïncidence du second plan de référence, défini par l'axe de la tige de clé et l'axe des aimants de clé, avec le premier plan de référence, du rotor.The round key orientation pin 12 will ensure the correct positioning of the key by aligning the second reference plane, defined by the axis of the key shank and the axis of the key magnets, with the first reference plane, of the rotor.

L'introduction de la clé dans la serrure est contrôlée par la coïncidence entre l'échancrure 23 de la tige de clé et la goupille 22 de solidarisation du rotor à la clé.The introduction of the key into the lock is controlled by the coincidence between the notch 23 of the key rod and the pin 22 securing the rotor to the key.

La concordance de profil entre l'échancrure 23 et la goupille 22 assure que la goupille 22 est bien positionnée et libère la ligne de césure entre rotor et stator, permettant la rotation du rotor. Cette concordance assure également la liaison mécanique entre la clé et le rotor pour réaliser la rotation du rotor. Cette concordance s'applique à toutes les goupilles de rotor et toutes les échancrures correspondantes de la tige de clé prévues entre les logements 25 et 18.The profile match between the notch 23 and the pin 22 ensures that the pin 22 is correctly positioned and frees the cut line between rotor and stator, allowing rotation of the rotor. This concordance also ensures the mechanical connection between the key and the rotor to achieve the rotation of the rotor. This agreement applies to all the rotor pins and all the corresponding notches of the key shank provided between the housings 25 and 18.
