Plus précisément, l'invention concerne un dispositif de blocage et de déblocage sélectif d'un mouvement d'actionnement, applicable à une serrure de sûreté, ce dispositif comprenant au moins une clef allongée suivant un axe et portant des reliefs de codage d'authenticité se succédant suivant l'axe longitudinal de la clef et s'étendant perpendiculairement à cet axe, un mécanisme de palpation des reliefs de codage d'authenticité, dans lequel la clef est sélectivement introduite par un mouvement de translation suivant son axe, un mécanisme d'authentification des reliefs de codage d'authenticité, et un rotor dans lequel sont logés les mécanismes de palpation et d'authentification, le mécanisme de palpation comprenant un ensemble de garnitures auxquelles les reliefs de la clef sont respectivement associés par une correspondance réciproque établie après introduction de la clef, ces garnitures adoptant, lors de l'introduction de la clef, des positions respectives contrôlées par les reliefs successifs de la clef et définissant collectivement une configuration dynamique du mécanisme de palpation se figeant en une configuration statique d'épreuve une fois la clef introduite, le mécanisme d'authentification fournissant une configuration de référence au plus tard après introduction de la clef, et le dispositif effectuant une comparaison entre la configuration d'épreuve et la configuration de référence, et adoptant un état de blocage ou de déblocage selon que la comparaison révèle, ou non, une correspondance entre les configurations comparées, chaque relief de la clef amené en regard d'une garniture assurant, dans la configuration dynamique du mécanisme de palpation, un guidage en rotation de cette garniture autour de l'axe longitudinal de la clef aussi bien dans le sens horaire que dans le sens anti-horaire, chaque relief imposant ainsi par lui-même à la garniture correspondante une orientation angulaire déterminée dans un plan transversal à l'axe longitudinal de la clef dans la configuration d'épreuve du mécanisme de palpation.More specifically, the invention relates to a device for locking and unlocking a selective actuating movement, applicable to a safety lock, this device comprising at least one elongate key along an axis and bearing embossing reliefs of authenticity succeeding along the longitudinal axis of the key and extending perpendicularly to this axis, a palpation mechanism embossing reliefs of authenticity, wherein the key is selectively introduced by a translation movement along its axis, a mechanism of authentication authenticity coding reliefs, and a rotor in which are housed the palpation and authentication mechanisms, the palpation mechanism comprising a set of fittings to which the reliefs of the key are associated respectively by a reciprocal correspondence established after introduction of the key, these trimmings adopting, at the time of the introduction of the key, respective positions contr by the successive reliefs of the key and collectively defining a dynamic configuration of the palpation mechanism congealing in a static test configuration once the key is entered, the authentication mechanism providing a reference configuration at the latest after introduction of the key, and the device performing a comparison between the test configuration and the reference configuration, and adopting a blocking or unblocking state depending on whether the comparison reveals, or not, a correspondence between the compared configurations, each relief of the key brought opposite a lining ensuring, in the dynamic configuration of the palpation mechanism, a guide in rotation of this lining around the longitudinal axis of the key both in the clockwise direction and in the counterclockwise direction, each relief thus imposing by itself on the corresponding lining an angular orientation determined in a plane tran sversal to the longitudinal axis of the key in the test configuration of the palpation mechanism.

Des dispositifs de ce type sont connus de l'art antérieur, comme par exemple du document de brevet publié sous le numéro CH87515. Un de ces dispositifs comprend une clef dont la partie avant porte des reliefs en forme de plats présentant différentes orientations. Les garnitures portent des plats complémentaires, qui viennent en contact avec les plats de la clef quand celle-ci est introduite dans le rotor, sous l'effet d'une force de rappel élastique ou non faisant pivoter la garniture autour d'un axe longitudinal. L'orientation du plat de la clef situé face au plat de la garniture détermine l'amplitude de la rotation de la garniture.Devices of this type are known from the prior art, such as for example the patent document published under the number CH87515. One of these devices includes a key whose the front part bears reliefs in the form of dishes with different orientations. The linings carry complementary dishes, which come into contact with the plates of the key when the latter is introduced into the rotor, under the effect of an elastic or non-elastic restoring force that pivots the lining around a longitudinal axis . The orientation of the flat of the key located opposite the flat of the lining determines the amplitude of the rotation of the lining.

Les garnitures portent chacune sur une face extérieure une rainure longitudinale. Quand l'orientation des plats de la clef et des plats complémentaires des garnitures est en concordance, c'est-à-dire quand le codage de la clef correspond à celui des garnitures, toutes les rainures sont alignées et forment une gorge continue.The linings each bear on an outer face a longitudinal groove. When the orientation of the dishes of the key and the complementary dishes of the linings is in agreement, that is to say when the coding of the key corresponds to that of the linings, all the grooves are aligned and form a continuous groove.

Une barre longitudinale de blocage peut alors s'escamoter dans la gorge, réalisant ainsi le déblocage du dispositif.A longitudinal locking bar can then retract into the groove, thus achieving the unlocking of the device.

La configuration d'épreuve dans ce dispositif est la configuration adoptée par les rainures portées par les garnitures. La configuration de référence est la forme de la barre longitudinale. La comparaison est effectuée en tournant la clef : si les garnitures ont adopté la configuration d'épreuve dans laquelle toutes les rainures sont alignées, le mouvement de rotation n'est pas bloqué par la barre. Si la configuration est différente, le mouvement de rotation est bloqué.The proof configuration in this device is the configuration adopted by the grooves worn by the fittings. The reference configuration is the shape of the longitudinal bar. The comparison is made by turning the key: if the gaskets have adopted the proof configuration in which all the grooves are aligned, the rotational movement is not blocked by the bar. If the configuration is different, the rotation movement is blocked.

Ce dispositif est complexe car un moyen de rappel élastique est associé à chaque garniture. De plus il est déjà bien connu des cambrioleurs, qui ont eu le temps d'adapter leurs outils et leurs méthodes à ce type de protection.This device is complex because an elastic return means is associated with each liner. Moreover, it is already well known burglars, who have had the time to adapt their tools and methods to this type of protection.

Dans ce contexte, la présente invention a pour but de pallier les difficultés mentionnées ci-dessous en proposant un dispositif simple fonctionnant suivant une technique nouvelle et qui est particulièrement difficile à crocheter.In this context, the present invention aims to overcome the difficulties mentioned below by providing a simple device operating according to a new technique and which is particularly difficult to crochet.

A cette fin, le dispositif de l'invention, par ailleurs conforme à la définition générique qu'en donne le préambule ci-dessus, est essentiellement caractérisé par ce qui est spécifié dans la partie caractérisante de la revendication 1.To this end, the device of the invention, moreover in conformity with the generic definition given in the preamble above, is essentially characterized by what is specified in the characterizing part of claim 1.

Dans la configuration dynamique du mécanisme de palpation, chaque relief de la clef amené en regard d'une garniture assure en outre un guidage en translation de cette garniture le long d'au moins un premier axe transversal contenu dans le plan transversal et aussi bien suivant l'une ou l'autre de deux directions antagonistes alignées sur ce premier axe transversal, chaque relief imposant ainsi par lui-même à la garniture correspondante une position de translation déterminée suivant ce premier axe transversal dans la configuration d'épreuve du mécanisme de palpation.In the dynamic configuration of the palpation mechanism, each relief of the key brought opposite a lining further ensures a guide in translation of the lining along at least a first transverse axis contained in the transverse plane and as well following one or the other of two opposing directions aligned on this first transverse axis, each relief thus imposing by itself to the corresponding lining a translation position determined along this first transverse axis in the test configuration of the palpation mechanism .

Avantageusement, le mécanisme d'authentification peut comprendre une pluralité d'éléments d'authentification auxquels les garnitures sont respectivement associées par une correspondance réciproque permanente, chaque élément d'authentification adoptant, dans le plan transversal et suivant le premier axe transversal, une position de translation déterminée par la position de translation de la garniture correspondante et, par rapport à l'axe longitudinal de la clef, une position de rotation liée par une fonction déterminée à la position de translation de cet élément d'authentification, les éléments d'authentification adoptant ainsi, lors de l'introduction de la clef, des positions respectives définissant collectivement une configuration dynamique du mécanisme d'authentification dépendant de la configuration dynamique du mécanisme de palpation et se figeant, une fois la clef introduite, dans la configuration de référence.Advantageously, the authentication mechanism may comprise a plurality of authentication elements to which the fittings are respectively associated by a permanent mutual correspondence, each authentication element adopting, in the transverse plane and along the first transverse axis, a position of translation determined by the translation position of the corresponding lining and, with respect to the longitudinal axis of the key, a rotational position linked by a specific function to the translation position of this authentication element, the authentication elements thus adopting, when introducing the key, respective positions collectively defining a dynamic configuration of the authentication mechanism dependent on the dynamic configuration of the palpation mechanism and freezing, once the key is introduced, in the reference configuration.

De préférence, chaque garniture peut être conformée en une bague percée d'un orifice central profilé dans lequel est sélectivement engagé un relief de la clef au moins, cette garniture offrant une surface externe présentant au moins une première section longitudinale cylindrique et une seconde section longitudinale rendue partiellement non cylindrique par une nervure axiale, l'élément d'authentification correspondant à cette garniture peut comprendre au moins une première couronne dentée percée d'un orifice d'authentification couvrant au moins les projections droites des première et seconde sections longitudinales de la garniture correspondante et dans lequel est engagée sans liberté de translation et à libre rotation la première section de la garniture correspondante dans la configuration dynamique du mécanisme de palpation, la première couronne dentée peut être montée mobile en translation dans une cavité oblongue du rotor délimitée par des premier et second bords allongés suivant le premier axe transversal, et la première couronne dentée peut engrener avec une crémaillère disposée sur le premier bord de la cavité oblongue pour adopter, autour de l'axe longitudinal, une position angulaire de rotation liée par une première fonction linéaire à sa position de translation dans la cavité oblongue.Preferably, each lining may be shaped into a ring pierced with a profiled central orifice in which is selectively engaged a relief of the key at least, this lining providing an external surface having at least a first cylindrical longitudinal section and a second longitudinal section. rendered partially non-cylindrical by an axial rib, the authentication element corresponding to this lining may comprise at least a first ring gear pierced with an authentication orifice covering at least the straight projections of the first and second longitudinal sections of the lining corresponding and in which is engaged without freedom of translation and free rotation the first section of the corresponding lining in the dynamic configuration of the palpation mechanism, the first ring gear can be mounted movable in translation in an oblong cavity of the rotor delimited by first and dry elongated edges along the first transverse axis, and the first ring gear can mesh with a rack disposed on the first edge of the oblong cavity to adopt, about the longitudinal axis, an angular position of rotation linked by a first linear function to its translation position in the oblong cavity.

Par exemple, chaque élément d'authentification peut comprendre une seconde couronne dentée percée d'un orifice d'authentification couvrant au moins les projections droites des première et seconde sections longitudinales de la garniture correspondante et dans lequel est engagée sans liberté de translation et à libre rotation la première section de la garniture correspondante dans la configuration dynamique du mécanisme de palpation, cette seconde couronne dentée peut être montée mobile en translation dans la même cavité oblongue du rotor que la première couronne dentée, et la seconde couronne dentée peut engrener avec une crémaillère disposée sur le second bord de la cavité oblongue pour adopter, autour de l'axe longitudinal, une position angulaire de rotation liée à sa position de translation dans la cavité oblongue par une deuxième fonction linéaire, variant en sens inverse de la première fonction linéaire.For example, each authentication element may comprise a second ring gear pierced with an authentication orifice covering at least the straight projections of the first and second longitudinal sections of the corresponding lining and in which is engaged without freedom of translation and free rotating the first section of the trim corresponding in the dynamic configuration of the palpation mechanism, this second ring gear can be mounted movably in translation in the same oblong cavity of the rotor as the first ring gear, and the second ring gear can mesh with a rack disposed on the second edge of the oblong cavity to adopt, around the longitudinal axis, an angular position of rotation related to its translational position in the oblong cavity by a second linear function, varying in the opposite direction of the first linear function.

Avantageusement, la comparaison entre la configuration d'épreuve et la configuration de référence peut être effectuée par un mouvement de translation de la clef, suivant son axe longitudinal, au-delà du mouvement d'introduction de la clef qui conduit aux configurations d'épreuve et de référence, le dispositif adoptant son état de déblocage lorsque chaque garniture peut s'engager dans l'orifice d'authentification de chaque couronne dentée de l'élément d'authentification correspondant à cette garniture, et adoptant son état de blocage au moins lorsque la nervure axiale de la seconde section longitudinale d'au moins une garniture bute sur un bord de l'orifice d'authentification d'au moins une couronne dentée de l'élément d'authentification correspondant à cette garniture.Advantageously, the comparison between the test configuration and the reference configuration can be performed by a translational movement of the key, along its longitudinal axis, beyond the insertion movement of the key which leads to the test configurations. and of reference, the device adopting its unlocking state when each lining can engage in the authentication opening of each ring gear of the authentication element corresponding to this lining, and adopting its blocking state at least when the axial rib of the second longitudinal section of at least one lining abuts on an edge of the authentication orifice of at least one toothed crown of the authentication element corresponding to this lining.

De préférence, au moins une garniture peut porter au moins un relief de leurre axial sur sa seconde section, la longueur axiale de ce leurre étant plus grande que la longueur axiale des nervures axiales portées par la garniture, les orifices d'authentification respectifs des première et seconde couronnes de l'élément d'authentification correspondant à la garniture peuvent comprendre chacun une pluralité d'encoches de sections axiales correspondant à la section axiale du leurre, le nombre d'encoches étant plus grand que le nombre de leurres portés par la garniture, et le leurre peut s'engager dans une encoche par translation axiale de la garniture alors que le dispositif est dans son état de blocage.Preferably, at least one lining may bear at least one relief of axial lure on its second section, the axial length of this lure being greater than the axial length of the axial ribs carried by the lining, the respective authentication orifices of the first and second rings of the authentication element corresponding to the lining may each comprise a plurality of slots with axial sections corresponding to the axial section of the lure, the number of notches being greater than the number of lures carried by the lining. , and the lure can engage in a notch by axial translation of the liner while the device is in its blocking state.

Par exemple, l'orifice central de chaque garniture peut présenter des sections transversales dont la taille varie longitudinalement, cette taille diminuant d'une extrémité longitudinale vers un plan médian de la garniture, et augmentant de façon symétrique du plan médian jusqu'à l'extrémité longitudinale opposée.For example, the central opening of each liner may have longitudinally-varying cross-sections, which size decreases from one longitudinal end to a mid-plane of the liner, and increases symmetrically from the mid-plane to the liner. opposite longitudinal end.

Avantageusement, les sections transversales de l'orifice central de chaque garniture peuvent présenter des formes polygonales ou lobées.Advantageously, the cross sections of the central orifice of each lining may have polygonal or lobed shapes.

De préférence, chaque garniture peut comprendre au moins trois nervures axiales, chaque couronne dentée peut comprendre de vingt sept à cinquante quatre dents et chaque crémaillère peut comprendre de trois à six dents.Preferably, each liner may comprise at least three axial ribs, each ring gear may comprise from twenty seven to fifty four teeth and each rack may comprise from three to six teeth.

Par exemple, le dispositif peut contenir au moins deux garnitures.For example, the device may contain at least two fittings.

Avantageusement, la clef peut comprendre une partie avant portant les reliefs de codage, cette partie avant présentant des sections transversales de formes enveloppes se déduisant les unes des autres par translation suivant un premier axe transversal et par rotation autour de l'axe longitudinal de la clef.Advantageously, the key may comprise a front portion carrying the coding reliefs, this front portion having transverse sections of envelopes forms derived from each other by translation along a first transverse axis and by rotation around the longitudinal axis of the key. .

Le dispositif de blocage et de déblocage sélectif d'un mouvement d'actionnement comprend, de façon connue, au moins une clef 10 allongée suivant un axe longitudinal 1 et portant sur une partie avant 11 des reliefs de codage d'authenticité 12, comme on peut le voir sur la figure 2. Cette partie avant 11 se termine par une tête 13.The device for selectively locking and unlocking an actuating movement comprises, in known manner, at least one key 10 elongated along a longitudinal axis 1 and bearing on a front portion 11 authenticity coding reliefs 12, as can be seen in FIG. can be seen in Figure 2. This front portion 11 ends with a head 13.

Ces reliefs 12 se succèdent suivant l'axe longitudinal 1 de la clef 10 et s'étendent perpendiculairement à cet axe.These reliefs 12 follow one another along the longitudinal axis 1 of the key 10 and extend perpendicularly to this axis.

Le dispositif comprend également un mécanisme de palpation 20 des reliefs de codage 12, dans lequel la clef 10 est sélectivement introduite par un mouvement de translation suivant son axe 1, un mécanisme d'authentification 30 des reliefs de codage 12, et un rotor 40 dans lequel sont logés les mécanismes de palpation et d'authentification 20 et 30.The device also comprises a palpating mechanism 20 of the coding reliefs 12, in which the key 10 is selectively introduced by a translation movement along its axis 1, an authentication mechanism 30 of the coding reliefs 12, and a rotor 40 in which houses the palpation and authentication mechanisms 20 and 30.

Le mécanisme de palpation 20 comprend un ensemble de garnitures 21 auxquelles les reliefs 12 de la clef 10 sont respectivement associés par une correspondance réciproque établie après introduction de la clef 10. Les garnitures 21 et les reliefs 12 sont donc en nombres identiques.The palpating mechanism 20 comprises a set of liners 21 to which the reliefs 12 of the key 10 are respectively associated by a mutual correspondence established after introduction of the key 10. The linings 21 and the reliefs 12 are therefore in identical numbers.

Ces garnitures 21 adoptent, pendant le mouvement d'introduction de la clef 10, des positions temporaires respectives contrôlées par les reliefs 12 successifs de la clef 10 et définissant collectivement une configuration dynamique du mécanisme de palpation 20.These linings 21 adopt, during the insertion movement of the key 10, respective temporary positions controlled by the successive reliefs 12 of the key 10 and collectively defining a dynamic configuration of the palpation mechanism 20.

Au cours de l'introduction de la clef, les garnitures 21 sont transitoirement associées à différents reliefs 12 de la clef suivant plusieurs correspondances successives. Cette configuration dynamique change à mesure que la clef 10 est introduite plus profondément dans le mécanisme de palpation 20.During the introduction of the key, the fittings 21 are transiently associated with different reliefs 12 of the key following several successive matches. This dynamic configuration changes as key 10 is introduced deeper into the palpating mechanism 20.

Cette configuration dynamique se fige en une configuration statique d'épreuve une fois la clef complètement introduite.This dynamic configuration freezes into a static proof configuration once the key is completely introduced.

Le mécanisme d'authentification 30 fournit une configuration statique de référence au plus tard après l'introduction de la clef.The authentication mechanism 30 provides a static reference configuration at the latest after the introduction of the key.

Le dispositif effectue une comparaison entre la configuration d'épreuve et la configuration de référence, et adopte un état de blocage ou de déblocage du mouvement d'actionnement selon que la comparaison révèle, ou non, une correspondance complète entre les configurations comparées.The device performs a comparison between the test pattern and the reference pattern, and adopts a blocking or unblocking state of the actuating movement depending on whether the comparison reveals a complete match between the compared patterns.

Selon l'invention, dans la configuration dynamique du mécanisme de palpation 20, chaque relief 12 de la clef 10 amené en regard d'une garniture 21 assure un guidage en rotation de cette garniture autour de l'axe longitudinal 1 de la clef, aussi bien dans le sens horaire que dans le sens anti-horaire.According to the invention, in the dynamic configuration of the palpation mechanism 20, each relief 12 of the key 10 brought opposite a lining 21 provides a guide in rotation of this lining around the longitudinal axis 1 of the key, also well clockwise than counter-clockwise.

Chaque relief 12 impose ainsi par lui-même à sa garniture 21 correspondante une orientation angulaire déterminée dans un plan transversal à l'axe longitudinal 1 de la clef 10 dans la configuration d'épreuve du mécanisme de palpation 20.Each relief 12 thus imposes by itself on its corresponding lining 21 an angular orientation determined in a plane transverse to the longitudinal axis 1 of the key 10 in the test configuration of the palpation mechanism 20.

Dans la configuration dynamique du mécanisme de palpation 20, chaque relief 12 de la clef amené en regard d'une garniture 21 assure en outre un guidage en translation de cette garniture 21 le long d'au moins un premier axe transversal 2 contenu dans le plan transversal.In the dynamic configuration of the palpation mechanism 20, each relief 12 of the key brought opposite a lining 21 further ensures a translational guide of this lining 21 along at least a first transverse axis 2 contained in the plane transverse.

Cette translation est orientée aussi bien suivant l'une ou l'autre de deux directions antagonistes alignées sur ce premier axe transversal 2.This translation is oriented equally along one or the other of two antagonistic directions aligned on this first transverse axis 2.

Chaque relief 12 impose ainsi par lui-même à sa garniture 21 correspondante une position de translation déterminée suivant ce premier axe transversal 2 dans la configuration d'épreuve du mécanisme de palpation 20.Each relief 12 thus imposes by itself on its corresponding lining 21 a translation position determined along this first transverse axis 2 in the test configuration of the palpation mechanism 20.

Le mécanisme d'authentification 30 comprend une pluralité d'éléments d'authentification 31 auxquels les garnitures 21 sont respectivement associées par une correspondance réciproque permanente.The authentication mechanism 30 comprises a plurality of authentication elements 31 to which the fittings 21 are respectively associated by a permanent mutual correspondence.

Le nombre d'éléments d'authentification 31 est donc identique au nombre de garnitures 21.The number of authentication elements 31 is therefore identical to the number of fittings 21.

Chaque élément d'authentification 31 adopte, dans le plan transversal et suivant le premier axe transversal 2, une position de translation déterminée par la position de translation de la garniture 21 correspondante et, par rapport à l'axe longitudinal 1 de la clef 10, une position de rotation liée par une fonction déterminée à la position de translation de cet élément d'authentification 31.Each authentication element 31 adopts, in the transverse plane and along the first transverse axis 2, a translation position determined by the translation position of the corresponding lining 21 and, with respect to the longitudinal axis 1 of the key 10, a rotational position linked by a determined function to the translation position of this authentication element 31.

Les éléments d'authentification 31 adoptent ainsi, lors de l'introduction de la clef 10, des positions respectives définissant collectivement une configuration dynamique du mécanisme d'authentification 30 dépendant de la configuration dynamique du mécanisme de palpation 20 et se figeant, une fois la clef introduite, dans la configuration de référence.The authentication elements 31 thus adopt, during the introduction of the key 10, respective positions that collectively define a dynamic configuration of the authentication mechanism that is dependent on the dynamic configuration of the palpation mechanism and that freezes once the key introduced, in the reference configuration.

Comme le montre la figure 10, chaque garniture 21 est conformée en une bague sensiblement cylindrique percée d'un orifice central 22 profilé dans lequel est sélectivement engagé un relief 12 de la clef au moins.As shown in Figure 10, each gasket 21 is shaped as a substantially cylindrical ring pierced with a central orifice 22 profiled in which is selectively engaged a relief 12 of the key at least.

La garniture 21 offre une surface externe 23 présentant au moins une première section longitudinale cylindrique 231 et une seconde section longitudinale 232 rendue partiellement non cylindrique par au moins une nervure axiale 24.The liner 21 has an outer surface 23 having at least a first longitudinal cylindrical section 231 and a second longitudinal section 232 rendered partially non-cylindrical by at least one axial rib 24.

La première section 231 et la partie cylindrique de la seconde section 232 sont de même diamètre et sensiblement de même longueur longitudinale.The first section 231 and the cylindrical portion of the second section 232 are of the same diameter and of substantially the same longitudinal length.

Les garnitures 21 portent typiquement trois nervures 24 réparties de façon régulière le long de la périphérie de la seconde section longitudinale 232.The liners 21 typically carry three ribs 24 distributed evenly along the periphery of the second longitudinal section 232.

Ces nervures 24 sont venues de matière avec la garniture. Chaque nervure est délimitée par une surface radiale 241 parallèle à la surface externe 23, deux bords longitudinaux 242 parallèles entre eux, et deux bords transversaux 243 parallèles entre eux sensiblement en secteurs d'anneau.These ribs 24 are integral with the liner. Each rib is delimited by a radial surface 241 parallel to the outer surface 23, two longitudinal edges 242 parallel to each other, and two transverse edges 243 parallel to each other substantially in ring sectors.

Chaque élément d'authentification 31 comprend au moins des première et seconde couronnes 32 et 33 minces identiques illustrées sur les figures 3 à 5. Chaque couronne 32, 33 présente un bord extérieur 321, 331 portant des dents 322, 332 sensiblement radiales. Ces couronnes 32, 33 sont également percées chacune d'un orifice d'authentification 323, 333 couvrant au moins les projections droites des première et seconde sections longitudinales 231, 232 de la garniture 21 correspondante, comme le montrent les figures 6 à 9.Each authentication element 31 comprises at least identical identical first and second rings 32 and 33 illustrated in FIGS. 3 to 5. Each ring 32, 33 has an outer edge 321, 331 carrying teeth 322, 332 that are substantially radial. These rings 32, 33 are also each pierced with an authentication orifice 323, 333 covering at least the straight projections of the first and second longitudinal sections 231, 232 of the corresponding lining 21, as shown in FIGS. 6 to 9.

Cet orifice d'authentification présente donc la forme d'un disque dont un bord extérieur porte trois découpes 324, 334 de la forme des nervures axiales 24, répartis régulièrement à sa périphérie.This authentication orifice thus has the shape of a disc whose outer edge carries three cutouts 324, 334 of the shape of the axial ribs 24, regularly distributed at its periphery.

Dans la configuration dynamique du mécanisme de palpation 20, la première section 231 de la garniture 21 correspondant à l'élément d'authentification 31 est engagée sans liberté de translation et à libre rotation dans les première et seconde couronnes 32 et 33, comme le montre par exemple la figure 8.In the dynamic configuration of the palpation mechanism 20, the first section 231 of the lining 21 corresponding to the authentication element 31 is engaged without freedom of translation and free rotation in the first and second rings 32 and 33, as shown for example in Figure 8.

Les première et seconde couronnes 32 et 33 sont concentriques et plaquées l'une contre l'autre.The first and second rings 32 and 33 are concentric and pressed against each other.

Le rotor 40 présente une forme générale de cylindre d'axe coaxial à l'axe longitudinal de la clef 10, et référencé 1 comme celui-ci. Ce rotor 40 comprend, comme le montre la figure 1, une plaque avant transversale 47, des cavités oblongues 41 transversales en nombre égal au nombre de garnitures 21, et une plaque arrière transversale 48.The rotor 40 has the general shape of a cylinder axis coaxial with the longitudinal axis of the key 10, and referenced 1 as the latter. This rotor 40 comprises, as shown in FIG. 1, a transverse front plate 47, transverse oblong cavities 41 equal in number to the number of linings 21, and a transverse rear plate 48.

La plaque avant 47, en forme générale de disque de centre 471, est percée d'un orifice 472 d'introduction de la clef 10. Cet orifice 472 comprend au moins une partie ronde située au centre de la plaque avant, cette partie ronde servant de palier de guidage en rotation de la clef 10.The front plate 47, in the general shape of a center disk 471, is pierced with a hole 472 for introducing the key 10. This orifice 472 comprises at least one round part situated at the center of the front plate, this round part serving bearing guide in rotation of the key 10.

La plaque arrière 48 présente sur une face intérieure un relief en creux non représenté sur les figures, de forme correspondante à celle de la tête 13 de la clef 10. Cette tête 13 vient s'engager dans le relief en creux quand la clef 10 est entièrement introduite dans le rotor 40.The rear plate 48 has on an inner face a recessed relief not shown in the figures, of a shape corresponding to that of the head 13 of the key 10. This head 13 engages in the recessed relief when the key 10 is completely introduced into the rotor 40.

Les cavités 41, illustrées sur la figure 11, sont toutes identiques et allongées suivant le premier axe transversal 2. Leurs sections transversales forment approximativement des ellipses de centre 411 et de grand axe selon le premier axe transversal 2.The cavities 41, illustrated in FIG. 11, are all identical and elongated along the first transverse axis 2. Their transverse sections form approximately center ellipses 411 and of major axis along the first transverse axis 2.

Les sections transversales de ces cavités 41 sont symétriques par rapport au premier axe transversal 2, et symétriques par rapport à un axe transversal perpendiculaire au premier axe transversal 2.The transverse sections of these cavities 41 are symmetrical with respect to the first transverse axis 2, and symmetrical with respect to a transverse axis perpendicular to the first transverse axis 2.

Deux cavités oblongues 41 voisines sont séparées par un voile 46 transversal, présentant une ouverture oblongue 461.Two adjacent oblong cavities 41 are separated by a transverse web 46, having an oblong opening 461.

Ces ouvertures 461 présentant deux bords allongés 463 opposés comprenant chacun une partie centrale droite 464 parallèle au premier axe transversal 2, et deux bords courbes reliant les bords allongés 463.These openings 461 having two opposite elongated edges 463 each comprising a central right portion 464 parallel to the first transverse axis 2, and two curved edges connecting the elongated edges 463.

Ces ouvertures 461 sont symétriques par rapport au premier axe transversal 2, et symétriques par rapport à un axe transversal perpendiculaire au premier axe transversal 2, et présentant un centre 462.These openings 461 are symmetrical with respect to the first transverse axis 2, and symmetrical with respect to a transverse axis perpendicular to the first transverse axis 2, and having a center 462.

La taille des ouvertures 461 est plus petite que la taille des sections transversales des cavités 41.The size of the openings 461 is smaller than the size of the cross sections of the cavities 41.

Le centre 471 de la plaque avant 47, les centres 411 des sections transversales des cavités 41, les centres 462 des ouvertures 461 des voiles 46 et le relief en creux de la plaque arrière 48 sont tous alignés selon un axe longitudinal.The center 471 of the front plate 47, the centers 411 of the cross-sections of the cavities 41, the centers 462 of the openings 461 of the webs 46 and the recessed relief of the rear plate 48 are all aligned along a longitudinal axis.

Chaque cavité oblongue 41 est associée de manière permanente à une garniture 21 et à un élément d'authentification 31.Each oblong cavity 41 is permanently associated with a lining 21 and an authentication element 31.

Chaque cavité oblongue 41 est délimitée par des premier et second bords allongés opposés 42 et 43 portant chacun en son centre une nervure de fixation longitudinale, respectivement 421 et 431.Each elongate cavity 41 is delimited by first and second opposite elongated edges 42 and 43 each carrying in its center a longitudinal fastening rib, respectively 421 and 431.

Une première crémaillère 44, illustrée sur la figure 3, est disposée dans chaque cavité oblongue 41. Elle se présente sous la forme d'une pièce métallique mince, d'épaisseur proche de l'épaisseur des première et seconde couronnes, et comprend un bord droit 441 dont deux extrémités opposées sont reliées par un bord concave 442.A first rack 44, illustrated in FIG. 3, is disposed in each oblong cavity 41. It is in the form of a thin metal piece, of thickness close to the thickness of the first and second rings, and comprises an edge right 441 which two opposite ends are connected by a concave edge 442.

Le bord droit 441 porte quatre dents 443 en son centre. Le bord concave 442 présente en son centre un évidement 444 de forme complémentaire à la section transversale de la nervure de fixation 421.The right edge 441 carries four teeth 443 at its center. The concave edge 442 has at its center a recess 444 of complementary shape to the cross section of the fastening rib 421.

La première crémaillère 44 est disposée dans la cavité oblongue 41, dans un plan transversal, la nervure de fixation 421 étant engagée dans l'évidement 444 de telle sorte que la crémaillère 44 soit liée en translation suivant le premier axe transversal 2. Les dents 443 sont alors tournées dans une direction perpendiculaire au premier axe transversal 2.The first rack 44 is disposed in the oblong cavity 41, in a transverse plane, the fixing rib 421 being engaged in the recess 444 so that the rack 44 is connected in translation along the first transverse axis 2. The teeth 443 are then rotated in a direction perpendicular to the first transverse axis 2.

La première couronne dentée 32 de l'élément d'authentification 31 correspondant à la cavité 41 est montée mobile en translation suivant le premier axe transversal 2 dans la cavité oblongue 41. Elle engrène avec la crémaillère 44, comme le montre la figure 3, de telle sorte que la première couronne 32 adopte une position angulaire de rotation autour de l'axe longitudinal 1 liée par une première fonction linéaire à sa position de translation dans la cavité oblongue 41.The first ring gear 32 of the authentication element 31 corresponding to the cavity 41 is mounted to move in translation along the first transverse axis 2 in the oblong cavity 41. It meshes with the rack 44, as shown in FIG. such that the first ring 32 adopts an angular position of rotation about the longitudinal axis 1 linked by a first linear function to its translational position in the oblong cavity 41.

Cette première fonction linéaire est fonction du nombre de dent de la crémaillère 44 et du nombre dé dent de la couronne 32.This first linear function is a function of the tooth number of the rack 44 and the number of teeth of the ring 32.

La couronne dentée 32 est guidée en translation le long du bord 42 par la crémaillère 44, et le long du bord 43 par une pièce de même forme que la crémaillère 44 mais dépourvue de dents, liée à la nervure 431. Cette pièce n'est pas représentée sur les figures 1 et 11.The ring gear 32 is guided in translation along the edge 42 by the rack 44, and along the edge 43 by a piece of the same shape as the rack 44 but devoid of teeth, connected to the rib 431. This piece is not shown in Figures 1 and 11.

Comme le montre la figure 1, la cavité oblongue 41 contient également une seconde crémaillère 45, identique à la première crémaillère 44, disposée de façon à ce que la nervure de fixation 431 soit engagée dans un évidement 454 porté par un bord concave 452 de la crémaillère 45.As shown in Figure 1, the oblong cavity 41 also contains a second rack 45, identical to the first rack 44, arranged so that the fixing rib 431 is engaged in a recess 454 carried by a concave edge 452 of the rack 45.

La seconde couronne 33 de l'élément d'authentification 31 correspondant à la cavité 41 est montée mobile en translation suivant le premier axe transversal 2 dans la cavité oblongue 41 et engrène avec la seconde crémaillère 45, comme le montre la figure 4.The second ring 33 of the authentication element 31 corresponding to the cavity 41 is mounted to move in translation along the first transverse axis 2 in the oblong cavity 41 and meshes with the second rack 45, as shown in FIG.

De même que la couronne 32, la couronne 33 est guidée en translation le long du bord 43 par la crémaillère 45, et le long du bord 42 par la pièce 46, visible sur la figure 11, dépourvue de dents mais de forme similaire à la crémaillère 44.Like the crown 32, the crown 33 is guided in translation along the edge 43 by the rack 45, and along the edge 42 by the piece 46, visible in Figure 11, devoid of teeth but similar in shape to the rack 44.

Ainsi, la seconde crémaillère 45 et la seconde couronne 33 d'une part, ét la première crémaillère 44 et à la première couronne 32 d'autre part, sont disposées symétriquement dans la cavité oblongue 41 par rapport au premier axe transversal 2. Les crémaillères 44 et 45 sont disposées en vis-à-vis dans la cavité oblongue 41.Thus, the second rack 45 and the second ring 33 on the one hand, and the first rack 44 and to the first ring gear 32 on the other hand, are arranged symmetrically in the oblong cavity 41 with respect to the first transverse axis 2. The racks 44 and 45 are arranged facing each other in the oblong cavity 41.

La seconde couronne 33 adopte une position angulaire de rotation autour de l'axe longitudinal liée par une seconde fonction linéaire à sa position de translation dans la cavité oblongue 41.The second ring 33 adopts an angular position of rotation about the longitudinal axis linked by a second linear function to its translational position in the oblong cavity 41.

Cette seconde fonction linéaire est fonction du nombre de dent de la crémaillère 45 et du nombre de dent de la couronne 33. Elle varie en sens inverse de la première fonction linéaire.This second linear function is a function of the tooth number of the rack 45 and the number of teeth of the ring 33. It varies inversely with the first linear function.

La taille de l'ouverture oblongue 461 du voile 46 est plus petite suivant au moins une direction que le diamètre des couronnes dentées 32 et 33, ces couronnes étant en conséquences prisonnières de la cavité oblongue 41.The size of the oblong opening 461 of the web 46 is smaller in at least one direction than the diameter of the toothed crowns 32 and 33, these rings being in consequence trapped in the oblong cavity 41.

L'épaisseur longitudinale de la cavité oblongue 41 correspond approximativement à l'épaisseur totale des première et seconde couronnes 32 et 33 plaquées l'une contre l'autre, de telle sorte que ces couronnes sont guidées dans leurs déplacements transversaux par les voiles 46.The longitudinal thickness of the oblong cavity 41 corresponds approximately to the total thickness of the first and second rings 32 and 33 pressed against each other, so that these crowns are guided in their transverse displacements by the webs 46.

La longueur longitudinale de chacune des première et seconde sections 231 et 232 de chaque garniture 21 est également sensiblement égale à l'épaisseur totale des première et seconde couronnes 32 et 33 plaquées l'une contre l'autre.The longitudinal length of each of the first and second sections 231 and 232 of each liner 21 is also substantially equal to the total thickness of the first and second rings 32 and 33 pressed against each other.

Les garnitures 21 sont alignées les unes derrière les autres dans le rotor 40 suivant une direction longitudinale, comme le montrent les figures 1 et 2. La première section 231 de chaque garniture 21 est du côté de la plaque arrière 48, et la seconde section 232 est du côté de la plaque avant.The liners 21 are aligned one behind the other in the rotor 40 in a longitudinal direction, as shown in Figures 1 and 2. The first section 231 of each lining 21 is on the side of the rear plate 48, and the second section 232 is on the side of the front plate.

Pendant la phase d'introduction de la clef 10 dans le rotor 40, la première section 231 de chaque garniture 21 est engagée dans les orifices d'authentification 323 et 333 des première et seconde couronnes 32 et 33 correspondantes, tandis que la seconde section 232 est engagée dans l'ouverture oblongue 461 du voile 46 bordant la cavité 41 correspondante côté plaque avant 47.During the introduction phase of the key 10 in the rotor 40, the first section 231 of each lining 21 is engaged in the authentication orifices 323. and 333 first and second rings 32 and 33 corresponding, while the second section 232 is engaged in the oblong opening 461 of the web 46 bordering the cavity 41 corresponding front plate side 47.

Quand la clef 10 est introduite dans le mécanisme de palpation 20, les garnitures 21 se déplacent suivant le premier axe transversal 2, et se déplacent en rotation autour de l'axe longitudinal 1, comme le montrent les flèches de la figure 6.When the key 10 is introduced into the palpation mechanism 20, the linings 21 move along the first transverse axis 2, and move in rotation about the longitudinal axis 1, as shown by the arrows of FIG. 6.

Quand la clef est entièrement introduite, chaque garniture 21 est traversé par la clef et a donc subi un déplacement suivant le premier axe transversal 2 correspondant au relief de codage 12 de la partie de la clef la traversant.When the key is fully inserted, each lining 21 is traversed by the key and has therefore been displaced along the first transverse axis 2 corresponding to the coding relief 12 of the part of the key passing therethrough.

Chaque garniture 21 entraîne les premières et seconde couronnes 32 et 33 correspondantes en translation le long du premier axe transversal 2, qui roulent sur les crémaillères 44 et 45 et subissent donc une rotation dans le plan transversal tout en restant concentriques.Each lining 21 drives the corresponding first and second rings 32 and 33 in translation along the first transverse axis 2, which roll on the racks 44 and 45 and are therefore rotated in the transverse plane while remaining concentric.

Les première et seconde couronnes 32 et 33 subissent des rotations en sens opposés.The first and second rings 32 and 33 undergo rotations in opposite directions.

Les orifices d'authentifications 323 et 333 subissent également des rotations en sens opposés. Ces rotations amènent les orifices d'authentification 323 et 333 et leurs découpes 324 et 334 dans des positions angulaires respectives déterminées. Ces positions angulaires peuvent ou non se superposer parfaitement, c'est-à-dire amener les trois découpes 324 et les trois découpes 334 à se superposer ou non.Authentication ports 323 and 333 also rotate in opposite directions. These rotations bring the authentication orifices 323 and 333 and their cutouts 324 and 334 into respective predetermined angular positions. These angular positions may or may not be superimposed perfectly, that is to say cause the three cuts 324 and the three cutouts 334 to be superimposed or not.

La garniture 21 subit elle-même une rotation sous l'influence du relief 12 correspondant de la clef 10, qui amène les trois nervures axiales 24 à une position angulaire prédéterminée.The lining 21 itself undergoes a rotation under the influence of the corresponding relief 12 of the key 10, which brings the three axial ribs 24 to a predetermined angular position.

La configuration d'épreuve correspond donc à l'ensemble des positions angulaires que vont adopter les nervures 24 des garnitures 21, sous l'influence des déplacements angulaires imposés par les reliefs de codage de la clef 12.The test configuration therefore corresponds to all the angular positions that will adopt the ribs 24 of the linings 21, under the influence of the angular displacements imposed by the coding reliefs of the key 12.

La configuration de référence correspond à l'ensemble des positions angulaires que vont adopter les découpes 324 et 334 des éléments d'authentification 31, sous l'influence des déplacements suivant le premier axe transversal 2 imposés par les reliefs de codage de la clef 12.The reference configuration corresponds to the set of angular positions that will adopt the cutouts 324 and 334 of the authentication elements 31, under the influence of the displacements along the first transverse axis 2 imposed by the coding reliefs of the key 12.

La comparaison entre la configuration d'épreuve et la configuration de référence est effectuée par un mouvement de translation de la clef 10, suivant son axe longitudinal, au-delà du mouvement d'introduction de la clef qui conduit aux configurations d'épreuve et de référence.The comparison between the test configuration and the reference configuration is effected by a translational movement of the key 10, along its longitudinal axis, beyond the insertion movement of the key which leads to the test and evaluation configurations. reference.

La clef 10 comprend un renflement 14 à une extrémité de sa partie avant 11, ce renflement 14 venant se positionner à l'intérieur de la partie ronde de l'orifice d'introduction de la clé 472 quand celle-ci est introduite dans le rotor 40 jusqu'au point conduisant aux configurations d'épreuve et de référence.The key 10 comprises a bulge 14 at one end of its front portion 11, this bulge 14 coming to be positioned inside the round part of the insertion orifice of the key 472 when the latter is introduced into the rotor 40 to the point leading to the test and reference configurations.

La clef 10, dans son mouvement au-delà de ce point, entraîne les garnitures 21 en translation par l'intermédiaire du renflement 14, qui vient pousser la garniture la plus proche de la plaque avant 47.The key 10, in its movement beyond this point, drives the linings 21 in translation through the bulge 14, which pushes the seal closest to the front plate 47.

Le dispositif adopte alors son état de déblocage lorsque chaque garniture 21 peut s'engager dans les orifices d'authentification 323 et 333 des couronnes dentées 32 et 33 de l'élément d'authentification 31 correspondant à cette garniture 21.The device then adopts its unlocking state when each lining 21 can engage in the authentication holes 323 and 333 of the toothed rings 32 and 33 of the authentication element 31 corresponding to this lining 21.

Ceci est possible si les positions angulaires de toutes les découpes 324, de toutes les découpes 334 et de toutes les nervures axiales 24 sont parfaitement correspondantes. Cette situation est représentée sur les figures 5, 7 et 8.This is possible if the angular positions of all the cuts 324, all the cuts 334 and all the axial ribs 24 are perfectly corresponding. This situation is represented in FIGS. 5, 7 and 8.

Le dispositif adopte son état de blocage au moins lorsque qu'une des nervures axiales 24 d'au moins une garniture 21 bute sur un bord de l'orifice d'authentification 323 ou 333 d'au moins une couronne dentée 32 ou 33 de l'élément d'authentification 31 correspondant à cette garniture 21.The device adopts its blocking state at least when one of the axial ribs 24 of at least one lining 21 abuts on an edge of the orifice 323 or 333 authentication of at least one ring gear 32 or 33 of the authentication element 31 corresponding to this lining 21.

Ceci est réalisé si au moins une découpe 324 n'est pas dans la même position angulaire qu'une découpe 334, ou si une nervure axiale n'est pas dans la même position angulaire qu'une découpe 324 ou une découpe 334. Une situation de ce type est représentée sur la figure 6.This is achieved if at least one cut 324 is not in the same angular position as a cut 334, or if an axial rib is not in the same angular position as a cut 324 or cut 334. A situation of this type is shown in FIG.

Quand le dispositif adopte son état de déblocage, le déplacement longitudinal des garnitures 21 amène les premières sections 231 des garnitures à s'engager au moins partiellement dans l'ouverture oblongue 461 du voile 46 bordant les cavités 41 correspondantes côté plaque arrière 47. Parallèlement, les secondes sections 232 des garnitures viennent s'engager au moins partiellement dans les orifices d'authentification 323 et 333 des première et seconde couronnes 32 et 33 correspondantes. Cette situation est représentée sur la figure 9.When the device adopts its unlocking state, the longitudinal displacement of the liners 21 causes the first sections 231 of the linings to engage at least partially in the oblong opening 461 of the web 46 bordering the corresponding cavities 41 corresponding to the rear plate 47. In parallel, the second sections 232 of the linings are engaged at least partially in the authentication holes 323 and 333 of the corresponding first and second rings 32 and 33. This situation is shown in Figure 9.

On notera que ce mouvement n'est possible que si un débattement existe entre la plaque arrière 48 et la cavité 41 la plus proche de celle-ci, et entre la plaque avant 47 et la cavité 41 la plus proche de celle-ci.Note that this movement is possible only if a clearance exists between the rear plate 48 and the cavity 41 closest thereto, and between the front plate 47 and the cavity 41 closest thereto.

Ces débattements sont par exemple créés en insérant un voile 46 supplémentaire entre la plaque avant 47 et la cavité 41 la plus proche, et un autre voile 46 entre la plaque arrière 48 et la cavité 41 la plus proche.These deflections are for example created by inserting an additional web 46 between the front plate 47 and the cavity 41 closest, and another web 46 between the rear plate 48 and the cavity 41 closest.

Le codage du dispositif est donc effectué en réalisant pour chaque garniture 21 les étapes suivantes.

  1. 1/ Choisir sur les crémaillères 44/45 de l'orifice oblong 41 correspondant à la garniture 21 la position transversale des couronnes 32 et 33 pour laquelle le déblocage sera réalisé ; cela revient à choisir le déplacement transversal de la garniture 21 pour lequel le déblocage sera réalisé.
  2. 2/ Choisir la position angulaire que les première et deuxième couronnes 32 et 33 occuperont dans la position transversale choisie au 1/ et pour laquelle le déblocage sera réalisé.
The coding of the device is therefore performed by performing for each lining 21 the following steps.
  1. 1 / Choose on the racks 44/45 of the oblong hole 41 corresponding to the lining 21 the transverse position of the rings 32 and 33 for which the unlocking will be performed; this amounts to choosing the transverse displacement of the lining 21 for which the unlocking will be performed.
  2. 2 / Choose the angular position that the first and second crowns 32 and 33 will occupy in the transverse position chosen at 1 / and for which the unlocking will be performed.

La forme de la partie avant 11 de la clef 10 et des reliefs de codage 12 peuvent se déduire une fois ces paramètres fixés.The shape of the front portion 11 of the key 10 and the coding reliefs 12 can be deduced once these parameters are set.

Pour rendre le crochetage du dispositif plus difficile, au moins une garniture 21, et en général toutes, porte au moins un relief de leurre axial 25 sur la seconde section 232 de sa surface externe 23, comme le montre par exemple la figure 10.To make the hooking of the device more difficult, at least one lining 21, and in general all, carries at least one relief of axial lure 25 on the second section 232 of its outer surface 23, as shown for example in FIG.

Ce leurre 25 se présente sous la forme d'une nervure venue de matière avec la garniture 21, longue et étroite, de section en demi-disque.This lure 25 is in the form of a rib formed integrally with the lining 21, long and narrow, half-disc section.

La longueur axiale de ce leurre 25 est plus grande que la longueur axiale des nervures axiales 24 portées par la garniture 21. Les leurres 25 se prolongent longitudinalement vers la première section 231 au-delà de l'extrémité des nervures 24.The axial length of this lure 25 is greater than the axial length of the axial ribs 24 carried by the lining 21. The lures 25 extend longitudinally towards the first section 231 beyond the end of the ribs 24.

Les orifices d'authentification 323 et 333 respectifs des première et seconde couronnes 32 et 33 de l'élément d'authentification 31 correspondant à la garniture 21 comprennent chacun une pluralité d'encoches 35 de sections axiales correspondant à la section axiale du leurre, visibles sur les figures 3 à 9.The respective authentication orifices 323 and 333 of the first and second rings 32 and 33 of the authentication element 31 corresponding to the lining 21 each comprise a plurality of notches 35 of axial sections corresponding to the axial section of the lure, which are visible. in Figures 3 to 9.

Le nombre d'encoches 35 est plus grand que le nombre de leurres 25 portés par la garniture 21.The number of notches 35 is greater than the number of decoys carried by the pad 21.

Le leurre 25 peut s'engager dans une encoche 35 par translation axiale de la garniture 21 alors que le dispositif est dans son état de blocage.The lure 25 can engage in a notch 35 by axial translation of the liner 21 while the device is in its blocking state.

Dans ce cas, le leurre 25 s'engage jusqu'à ce qu'une nervure axiale 24 de la garniture 21 vienne buter sur une couronne dentée 32 ou 33.In this case, the lure 25 engages until an axial rib 24 of the lining 21 abuts on a ring gear 32 or 33.

Cette caractéristique du dispositif rend plus difficile à un crocheteur de tester pour chaque garniture 21 individuellement les positions angulaires qui permettent d'engager la dite garniture dans les couronnes dentées associées.This feature of the device makes it more difficult for a picker to test for each liner 21 individually the angular positions that allow to engage said lining in the associated toothed crowns.

Quand le dispositif peut adopter sa position de déblocage, les leurres 25 sont alignés avec des encoches 35. Le mouvement axial de la clef 10 par lequel la comparaison entre les configurations d'épreuve et de référence est effectuée entraîne l'engagement des leurres 25 dans ces encoches 35 correspondantes, comme on peut le voir sur les figures 7 à 9.When the device can adopt its unlocking position, the decoys 25 are aligned with notches 35. The axial movement of the key 10 by which the comparison between the test and reference configurations is performed causes the decoys 25 to engage in these corresponding notches, as can be seen in Figures 7 to 9.

Dans le mode de réalisation représenté sur les figures 1 à 10, les garnitures portent 6 leurres répartis régulièrement entre les nervures, et les couronnes dentées portent 12 encoches chacune, réparties régulièrement entre les découpes 324 et 334.In the embodiment shown in Figures 1 to 10, the fittings have 6 lures regularly distributed between the ribs, and the ring gear 12 notches each, evenly distributed between the cuts 324 and 334.

L'orifice central 22 de chaque garniture 21 présente des sections transversales dont la taille varie longitudinalement. Cette taille diminue d'une extrémité longitudinale vers un plan médian de la garniture 21, et augmente de façon symétrique du plan médian jusqu'à l'extrémité longitudinale opposée de la garniture 21. L'orifice central présente donc des bords biseautés dans le sens longitudinal.The central orifice 22 of each liner 21 has cross sections whose size varies longitudinally. This size decreases from one longitudinal end to a median plane of the lining 21, and increases symmetrically from the median plane to the opposite longitudinal end of the lining 21. The central orifice thus has beveled edges in the direction longitudinal.

Cette caractéristique est particulièrement avantageuse car la clef 10 présente sur sa partie avant 11 des reliefs 12 pouvant former entre eux des angles marqués. Les bords biseautés de l'orifice central 22 permettent d'introduire la clef à travers la garniture malgré ces angles marqués.This feature is particularly advantageous because the key 10 has on its front portion 11 reliefs 12 can form between them marked angles. The beveled edges of the central orifice 22 allow to introduce the key through the liner despite these marked angles.

Les sections transversales de l'orifice central 22 de chaque garniture 21 présentent des formes sensiblement triangulaires équilatérales. Les angles de ces triangles sont coupés.The cross sections of the central orifice 22 of each lining 21 have substantially equilateral triangular shapes. The angles of these triangles are cut off.

D'autres formes peuvent également être adaptées, carrée, pentagonale, polygonale, ou même lobée.Other shapes can also be adapted, square, pentagonal, polygonal, or even lobed.

Dans le mode de réalisation de l'invention décrit ci-dessus, chaque garniture 21 comprend trois nervures axiales 24. Ces nervures sont situées dans des positions angulaires correspondantes à celles des angles de l'orifice central 22.In the embodiment of the invention described above, each lining 21 comprises three axial ribs 24. These ribs are located in angular positions corresponding to those of the angles of the central orifice 22.

Il est possible d'utiliser un nombre plus grand de nervures axiales, quatre ou même plus, sans sortir de l'invention.It is possible to use a larger number of axial ribs, four or even more, without departing from the invention.

Dans le mode de réalisation illustré par les figures 1 à 10, chaque couronne dentée comprend 36 dents, et chaque crémaillère comprend quatre dents.In the embodiment illustrated in Figures 1 to 10, each ring gear comprises 36 teeth, and each rack comprises four teeth.

Ces nombres de dents sont adéquats pour le but recherché, mais il est possible de mettre en oeuvre le dispositif de l'invention par exemple avec des crémaillères de trois à six dents et des couronnes de vingt sept à cinquante quatre dents.These numbers of teeth are adequate for the desired purpose, but it is possible to implement the device of the invention for example with racks of three to six teeth and crowns of twenty seven to fifty four teeth.

Le dispositif contient six garnitures dans le mode de réalisation illustré par les figures 1 à 10. Il peut également être utilisé avec un nombre inférieur de garnitures, ou supérieur.The device contains six packings in the embodiment illustrated in FIGS. 1-10. It may also be used with a lower number of packings, or higher.

Plus le nombre de garniture est petit, plus le niveau de sûreté du dispositif est faible.The smaller the number of lining, the lower the level of safety of the device.

Réciproquement, un nombre élevé de garniture assure une sûreté plus élevé, mais augmente le coût et force à diminuer la taille de chaque relief de codage. En deçà d'une taille minimum, il y a un risque de dysfonctionnement du dispositif.Conversely, a high number of lining provides a higher safety, but increases the cost and forces to decrease the size of each coding relief. Below a minimum size, there is a risk of malfunction of the device.

Le dispositif peut ne comprendre qu'une seule couronne par garniture, de façon à simplifier le mécanisme et/ou à autoriser plusieurs translations donc à accepter plusieurs clefs.The device may comprise only one crown per lining, so as to simplify the mechanism and / or to allow several translations thus to accept several keys.

La clef 10 porte sur sa partie avant 11 les reliefs de codage 12. Cette partie avant 11 présente des sections transversales de formes enveloppes se déduisant les unes des autres par translation suivant le premier axe transversal 2 et par rotation autour de l'axe longitudinal 1 de la clef 10.The key 10 bears on its front portion 11 the coding reliefs 12. This front portion 11 has cross-sections of envelopes forms deduced from each other by translation along the first transverse axis 2 and by rotation about the longitudinal axis 1 of the key 10.

Pour faciliter le montage du dispositif, le rotor est divisé suivant un plan longitudinal en deux demi-cylindres.To facilitate assembly of the device, the rotor is divided along a longitudinal plane into two half-cylinders.

Ces demi-cylindres sont solidarisés l'un à l'autre par des moyens classiques, comme par exemple des vis ou des rivets.These half-cylinders are secured to one another by conventional means, such as screws or rivets.

On conçoit bien que le dispositif décrit ci-dessus est particulièrement difficile à crocheter. La configuration d'épreuve du mécanisme est en effet obtenu par un double mouvement des garnitures, suivant une direction transversale et en rotation. La configuration de référence des éléments d'authentification résulte également d'un double mouvement, le déplacement angulaire étant lié au déplacement latéral par l'intermédiaire des crémaillères. Les éléments d'authentification comprennent deux couronnes roulant en sens inverse, ce qui rend le crochetage du dispositif encore plus compliqué. Enfin, le principe de fonctionnement du dispositif est nouveau et encore inconnu des crocheteurs.It is understood that the device described above is particularly difficult to crochet. The proof configuration of the mechanism is indeed obtained by a double movement of the linings, in a transverse direction and in rotation. The reference configuration of the authentication elements also results from a double movement, the angular displacement being linked to the lateral displacement by means of the racks. The authentication elements comprise two crowns rolling in opposite directions, which makes the hooking of the device even more complicated. Finally, the operating principle of the device is new and still unknown to the hookers.
