Knock lock cylinders include:
  • a stator comprising:
    • a central notch extending in a transverse plane, this transverse plane dividing the stator into an inner half-stator and an outer half-stator,
    • a longitudinal hole extending along a longitudinal axis perpendicular to the transverse plane and passing through the inner and outer half-stators and the central notch, and
    • a first annular face formed on the inner half-stator and a second annular face formed on the outer half-stator, these annular faces being each disposed on a respective side of the notch, each of these first and second annular faces being turned on the opposite side to the longitudinal axis and has a symmetry of revolution about the longitudinal axis,

  • a bit for driving the movement of a bolt of the lock, this bit being housed inside the notch and comprising third and fourth annular faces facing the longitudinal axis and each having a symmetry of revolution around the longitudinal axis, these third and fourth annular faces being directly bearing on, respectively, the first and second annular faces of the stator to form a pivot connection between the bit and the stator allowing the bit to rotate about the longitudinal axis, this bit being also mechanically connected to the rotor to be rotated about the longitudinal axis by the rotor,
  • a locking member movable between:
    • a locking position in which it is engaged with the rotor to lock it in rotation, and
    • a retracted position in which it releases the rotation of the rotor.

Par exemple, un tel cylindre de serrure est divulgué dans la demande de brevet CH674543 .For example, such a lock cylinder is disclosed in the patent application CH674543 .

Par rapport à d'autres cylindres connus, le cylindre de la demande CH674543 est plus robuste et plus résistant aux tentatives d'effraction. En effet, contrairement à la majorité des cylindres de serrure connus, le panneton est monté en rotation sur le stator. Par conséquent, si un cambrioleur perce un trou à l'emplacement du rotor, cela détruit le rotor mais n'endommage pas le panneton qui est donc retenu en place par le stator. Le panneton reste donc apte à maintenir la serrure dans sa position verrouillée.Compared to other known cylinders, the cylinder of demand CH674543 is more robust and more resistant to burglary attempts. Indeed, unlike the majority of lock cylinders known, the bit is rotatably mounted on the stator. Therefore, if a burglar drills a hole at the rotor location, it destroys the rotor but does not damage the bit which is held in place by the stator. The bit remains able to keep the lock in its locked position.

Par contre, le cylindre de CH674543 est complexe à réaliser et à assembler. En particulier, l'assemblage du panneton sur le stator nécessite plusieurs pièces mobiles, dont notamment une pièce d'engrènement 28 (Figure 6 de CH674543 ), ce qui en complexifie la réalisation et l'assemblage.On the other hand, the cylinder of CH674543 is complex to make and assemble. In particular, the assembly of the bit on the stator requires several moving parts, including in particular a meshing piece 28 ( Figure 6 of CH674543 ), which complicates the production and assembly.

De l'état de la technique est également connu de FR2762638A1 , EP2708681A2 , GB2288204A , DE3418680A1 , EP0736653A2 , EP1516983A1 .From the state of the art is also known from FR2762638A1 , EP2708681A2 , GB2288204A , DE3418680A1 , EP0736653A2 , EP1516983A1 .

L'invention vise à proposer un cylindre de serrure ayant le même avantage que le cylindre de CH674543 tout en étant plus simple à réaliser. Elle a donc pour objet un cylindre de serrure conforme à la revendication 1.The aim of the invention is to propose a lock cylinder having the same advantage as the cylinder of CH674543 while being simpler to achieve. It therefore relates to a lock cylinder according to claim 1.

Grâce au mécanisme électronique, c'est le même organe de blocage qui se déplace entre sa position de blocage et sa position escamotée pour déverrouiller la serrure, quel que soit le côté par lequel on introduit la clef autorisée. Ce cylindre ne nécessite donc qu'un seul rotor sur lequel le panneton est systématiquement et continûment engrené en rotation. Les pièces d'engrènement, telles que la pièce 28 de CH674543 , peuvent donc être omises.Thanks to the electronic mechanism, it is the same locking member which moves between its locking position and its retracted position to unlock the lock, regardless of the side by which the authorized key is introduced. This cylinder therefore requires only one rotor on which the bit is systematically and continuously meshed in rotation. The meshing parts, such as 28 CH674543 , can be omitted.

La serrure ci-dessus est donc plus simple à fabriquer tout en conservant la robustesse du cylindre de serrure de la demande CH674543 , puisque le panneton est aussi monté en rotation sur le stator et non pas sur le rotor.The lock above is therefore simpler to manufacture while maintaining the robustness of the lock cylinder of the application. CH674543 since the bit is also mounted in rotation on the stator and not on the rotor.

Les modes de réalisation de ce cylindre de serrure peuvent comporter une ou plusieurs des caractéristiques des revendications dépendantes.Embodiments of this lock cylinder may include one or more of the features of the dependent claims.

Ces modes de réalisation du cylindre de serrure présentent en outre les avantages suivants :

  • Le fait que des nervures et des rainures engagées l'une à l'intérieur de l'autre soient ménagées, de chaque côté de l'encoche, entre le stator et le panneton permet de renforcer la solidité du cylindre vis-à-vis de toute tentative de rupture du stator au niveau du plan transversal. En effet, grâce à ces nervures et ces rainures, les demi-stators extérieur et intérieur sont en plus directement mécaniquement raccordés l'un à l'autre par l'intermédiaire du panneton et ceci sans aucun degré de liberté en translation parallèlement à l'axe longitudinal. Ceci accroît notablement la résistance du cylindre aux tentatives d'effraction.
  • Utiliser les mêmes rainures et nervures comme face annulaire pour créer la liaison pivot entre le panneton et le stator simplifie la fabrication du cylindre puisque alors ces rainures et nervures remplissent simultanément deux fonctions différentes.
  • La présence d'une collerette en saillie à l'intérieur de l'encoche sur le rotor permet d'améliorer la robustesse du cylindre vis-à-vis des tentatives d'effraction mettant en oeuvre la réalisation d'un perçage à travers le rotor. En effet, dans ce cas, aucune partie du panneton ne fait saillie à l'intérieur du trou longitudinal dans lequel est logé le rotor. Dès lors, le perçage du rotor ne peut pas endommager le panneton, ce qui préserve l'efficacité de ce panneton pour maintenir la serrure verrouillée. De plus, cette collerette renforce également le cylindre vis-à-vis des tentatives d'arrachement du rotor. En effet, la collerette est coincée entre les deux demi-stators, ce qui le rend plus difficile à arracher.
  • La présence d'un renflement cylindrique sur le rotor coincé entre les deux demi-stators permet d'augmenter encore plus la résistance du cylindre à l'arrachement du rotor.
  • L'utilisation de deux demi-pannetons articulés pour réaliser le panneton permet de monter le panneton sur le rotor et le stator après que le rotor ait été introduit à l'intérieur du stator. Cela facilite le montage du cylindre. Cela permet aussi de simplifier la conception du cylindre en évitant le recours à un cylindre creux comme le cylindre creux 2 décrit dans la demande CH674543 .
  • La réalisation du stator du cylindre à l'aide de deux coquilles et d'une barre de liaison simplifie l'assemblage du stator tout en conservant une grande robustesse à ce cylindre de serrure.
These embodiments of the lock cylinder also have the following advantages:
  • The fact that ribs and grooves engaged one inside the other are formed on each side of the notch, between the stator and the bit allows to strengthen the strength of the cylinder vis-à-vis any attempt to break the stator at the transverse plane. Indeed, thanks to these ribs and these grooves, the outer and inner half-stators are more directly mechanically connected to each other via the bit and this without any degree of freedom in translation parallel to the longitudinal axis. This significantly increases the resistance of the cylinder to burglary attempts.
  • Using the same grooves and ribs as the annular face to create the pivot connection between the bit and the stator simplifies the manufacture of the cylinder since then these grooves and ribs simultaneously perform two different functions.
  • The presence of a protruding flange inside the notch on the rotor makes it possible to improve the robustness of the cylinder vis-à-vis the attempts of burglar performs drilling through the rotor. Indeed, in this case, no part of the bit protrudes inside the longitudinal hole in which is housed the rotor. Therefore, drilling the rotor can not damage the bit, which preserves the effectiveness of this bit to keep the lock locked. In addition, this collar also strengthens the cylinder vis-à-vis attempts to tear the rotor. Indeed, the collar is wedged between the two half-stators, which makes it more difficult to tear.
  • The presence of a cylindrical bulge on the rotor wedged between the two half-stators makes it possible to further increase the resistance of the cylinder to tearing the rotor.
  • The use of two half-pannette articulated to achieve the bit allows to mount the bit on the rotor and the stator after the rotor has been introduced inside the stator. This facilitates the mounting of the cylinder. This also makes it possible to simplify the cylinder design by avoiding the use of a hollow cylinder such as the hollow cylinder 2 described in the application CH674543 .
  • The realization of the stator of the cylinder with two shells and a connecting bar simplifies the assembly of the stator while maintaining great strength to the lock cylinder.

Dans ces figures, les mêmes références numériques sont utilisées pour désigner les mêmes éléments. Dans la suite de cette description, les caractéristiques et fonctions bien connues de l'homme du métier ne sont pas décrites en détail.In these figures, the same reference numerals are used to designate the same elements. 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 une porte 2. Cette porte 2 présente un côté intérieur, typiquement situé à l'intérieur d'une pièce, et un côté extérieur du côté opposé. Par la suite, les termes « intérieur » et « extérieur » font référence, respectivement, au côté intérieur et extérieur de la porte 2. La porte 2 s'étend ici dans un plan vertical. Par la suite, la direction verticale est désignée par la direction Z d'un repère orthogonal XYZ. La direction X est perpendiculaire au plan vertical dans lequel s'étend principalement la porte 2. L'ensemble des figures sont orientées par rapport à ce repère XYZ.The figure 1 is a door 2. This door 2 has an inner side, typically located within a room, and an outer side of the opposite side. Subsequently, the terms "inner" and "outer" refer, respectively, to the inner and outer side of the door 2. The door 2 here extends in a vertical plane. Thereafter, the vertical direction is indicated by the direction Z of an orthogonal reference XYZ. The direction X is perpendicular to the vertical plane in which the door 2 extends mainly. All the figures are oriented relative to this XYZ mark.

La porte 2 est équipée d'une poignée 4 et d'une serrure 6. Pour simplifier la figure 1, seule une partie de la porte 2 est représentée.The door 2 is equipped with a handle 4 and a lock 6. To simplify the figure 1 only part of the door 2 is shown.

La serrure 6 comporte un pêne 10 déplaçable en translation, parallèlement à la direction Y, en alternance et de façon réversible, entre une position verrouillée et une position déverrouillée. Dans la position verrouillée, le pêne 10 fait saillie au-delà de la tranche de la porte 2 pour s'engager dans une gâche fixée sans aucun degré de liberté sur le dormant de la porte 2. Dans la position verrouillée, le pêne 10 verrouille la porte 2 dans sa position fermée. Dans la position déverrouillée, le pêne 10 est rentré à l'intérieur de la porte 2 et ne fait plus saillie au-delà de la tranche de cette porte 2. Dans la position déverrouillée, la porte 2 peut être déplacée par un utilisateur d'une position fermée vers une position ouverte en actionnant la poignée 4.The lock 6 comprises a bolt 10 movable in translation, parallel to the Y direction, alternately and reversibly, between a locked position and an unlocked position. In the locked position, the bolt 10 protrudes beyond the edge of the door 2 to engage in a strike fixed without any degree of freedom on the frame of the door 2. In the locked position, the bolt 10 locks the door 2 in its closed position. In the unlocked position, the bolt 10 is returned inside the door 2 and no longer protrudes beyond the edge of this door 2. In the unlocked position, the door 2 can be moved by a user of a closed position to an open position by actuating the handle 4.

La serrure 6 comporte aussi un cylindre 12 et une vis 14 de fixation du cylindre 12 dans la porte 2. Le cylindre 12 déplace le pêne 10 de sa position verrouillée vers sa position déverrouillée lorsqu'une clef 16 (figure 2), autorisée à déverrouiller la serrure 6, est introduite, puis tournée à l'intérieur de ce cylindre. Le cylindre 12 déplace aussi le pêne 10 de sa position déverrouillée vers sa position verrouillée lorsque la clef autorisée est introduite puis tournée en sens inverse à l'intérieur de ce cylindre. À l'inverse, lorsqu'une clef non-autorisée est introduite à l'intérieur du cylindre 12, ce cylindre empêche le déplacement du pêne 10 de sa position verrouillée vers sa position déverrouillée.The lock 6 also comprises a cylinder 12 and a screw 14 for fixing the cylinder 12 in the door 2. The cylinder 12 moves the bolt 10 from its locked position to its unlocked position when a key 16 ( figure 2 ), allowed to unlock the lock 6, is introduced and then turned inside this cylinder. The cylinder 12 also moves the bolt 10 from its unlocked position to its locked position when the authorized key is inserted and turned in the opposite direction inside this cylinder. Conversely, when an unauthorized key is introduced inside the cylinder 12, the cylinder prevents the displacement of the bolt 10 from its locked position to its unlocked position.

Ici, la clef 16 peut être introduite à l'intérieur du cylindre 12 depuis le côté extérieur et, en alternance, depuis le côté intérieur de la porte 2. À cet effet, le cylindre 12 débouche de chaque côté de la porte 2.Here, the key 16 can be introduced inside the cylinder 12 from the outside and, alternately, from the inside of the door 2. For this purpose, the cylinder 12 opens on each side of the door 2.

La vis 14 comporte une tête qui affleure sur la tranche de la porte 2. L'extrémité taraudée de la vis 14 est vissée dans le cylindre 12 pour le retenir en place à l'intérieur de la porte 2.The screw 14 has a head that is flush with the edge of the door 2. The threaded end of the screw 14 is screwed into the cylinder 12 to hold it in place inside the door 2.

La figure 2 représente plus en détail le cylindre 12. Ici, le cylindre 12 est conforme au format européen. Le cylindre 12 s'étend le long d'un axe longitudinal 20 parallèle à la direction X. Il comporte un stator 22 fixé sans aucun degré de liberté à la porte 2 par l'intermédiaire de la vis 14 et un panneton 24 logé à l'intérieur d'une encoche transversale 26.The figure 2 represents in more detail the cylinder 12. Here, the cylinder 12 is in accordance with the European format. The cylinder 12 extends along a longitudinal axis 20 parallel to the direction X. It comprises a stator 22 fixed without any degree of freedom to the door 2 by means of the screw 14 and a bit 24 housed inside a transverse notch 26.

L'encoche 26 s'étend dans un plan transversal 28 parallèle aux directions Y, Z. Ici, seule une partie du plan 28 est représentée sur la figure 2. Le plan 28 est un plan de symétrie pour le panneton 24.The notch 26 extends in a transverse plane 28 parallel to the directions Y, Z. Here, only part of the plane 28 is represented on the figure 2 . The plane 28 is a plane of symmetry for the bit 24.

Le panneton 24 tourne dans le sens trigonométrique autour de l'axe 20 pour déplacer le pêne 10 de sa position verrouillée vers sa position déverrouillée et dans le sens inverse pour déplacer le pêne 10 de sa position déverrouillée vers sa position verrouillée.The bit 24 rotates counterclockwise about the axis 20 to move the bolt 10 from its locked position to its unlocked position and in the opposite direction to move the bolt 10 from its unlocked position to its locked position.

Le plan 28 divise également le stator 22 en deux parties. La partie du stator 22 située du côté intérieur de la porte 2 est appelée « demi-stator intérieur » et porte la référence 30. La partie du stator 22 située du côté extérieur de la porte 2 est appelée « demi-stator extérieur» et porte la référence 32. Dans ce mode de réalisation particulier, les demi-stators 30 et 32 sont quasiment les symétriques l'un de l'autre par rapport au plan 28. Ainsi, seul le demi-stator 32 est décrit plus en détail par la suite car la forme du demi-stator 30 se déduit des explications données pour le demi-stator 32.The plane 28 also divides the stator 22 into two parts. The part of the stator 22 located on the inside of the door 2 is called "inner half-stator" and has the reference 30. The portion of the stator 22 located on the outside of the door 2 is called "outer half-stator" and door In this particular embodiment, the half-stators 30 and 32 are almost symmetrical to one another with respect to the plane 28. Thus, only the half-stator 32 is described in more detail by the following because the shape of the half-stator 30 is deduced from the explanations given for the half-stator 32.

Le demi-stator 32 comporte un cache avant 34 parallèle au plan 28 et directement exposé à l'extérieur de la porte 2. Ce cache avant empêche d'avoir un accès direct aux pièces mobiles situées à l'intérieur du cylindre 12 de manière à les protéger contre des tentatives d'effraction. Ce cache 34 est traversé par un orifice 36 destiné à recevoir une tige 38 de la clef 16. L'orifice 36 est centré sur l'axe 20. L'orifice 36 est conformé de manière à permettre l'introduction de la tige 38 à l'intérieur du cylindre 12 par un mouvement de translation parallèle à la direction X. L'orifice 36 est aussi conformé pour permettre à la clef 16 introduite à l'intérieur du cylindre 12 de tourner sur elle-même autour de l'axe 20.The half-stator 32 comprises a front cover 34 parallel to the plane 28 and directly exposed to the outside of the door 2. This front cover prevents direct access to the moving parts located inside the cylinder 12 so as to protect them from burglary attempts. This cover 34 is traversed by an orifice 36 intended to receive a rod 38 of the key 16. The orifice 36 is centered on the axis 20. The orifice 36 is shaped so as to allow the introduction of the rod 38 to the inside of the cylinder 12 by a translational movement parallel to the X direction. The orifice 36 is also shaped to allow the key 16 introduced inside the cylinder 12 to turn on itself about the axis 20 .

Ici, la clef 16 est une clef électronique apte à transmettre un code d'accès au cylindre 12 pour que celui-ci, en réponse :

  • autorise le déverrouillage de la serrure 6 si le code d'accès reçu est celui d'une clef autorisée à ouvrir la porte 2, et en alternance
  • interdise le déverrouillage de la serrure 6 si le code d'accès reçu est celui d'une clef non-autorisée.
Here, the key 16 is an electronic key capable of transmitting an access code to the cylinder 12 so that it, in response:
  • authorizes the unlocking of the lock 6 if the access code received is that of a key authorized to open the door 2, and alternately
  • prohibits the unlocking of the lock 6 if the access code received is that of an unauthorized key.

À cet effet, la clef 16 comporte un transpondeur 40. Par exemple, le transpondeur 40 est une étiquette RFID (Radio Frequency Identification). Cette technologie est bien connue. Par exemple, celle-ci est décrite dans les demandes de brevet FR2945065 et FR2945308 . Elle ne sera donc pas décrite ici plus en détail.For this purpose, the key 16 comprises a transponder 40. For example, the transponder 40 is a RFID (Radio Frequency Identification) tag. This technology is well known. For example, this is described in patent applications FR2945065 and FR2945308 . It will not be described here in more detail.

Dans ces conditions, la tige 38 est pourvue de motif en relief destiné à déplacer des goupilles de la serrure pour provoquer un déverrouillage mécanique de la serrure 6. Par contre, la tige 38 comporte au moins un motif apte à coopérer avec un motif de forme complémentaire sur un rotor du cylindre 12 pour entraîner ce rotor en rotation lorsque la clef tourne. Ici, ce motif sur la tige 38 est un méplat 42 situé sur son extrémité libre.Under these conditions, the rod 38 is provided with a raised pattern for moving pins of the lock to cause mechanical unlocking of the lock 6. By cons, the rod 38 has at least one pattern adapted to cooperate with a pattern of complementary shape on a rotor of the cylinder 12 for driving the rotor in rotation when the key rotates. Here, this pattern on the rod 38 is a flat portion 42 located on its free end.

Sous l'encoche 26 et dans le plan 28, le cylindre 12 comporte un trou taraudé 44, s'étendant parallèlement à la direction Y. Ce trou 44 reçoit la vis 14 pour fixer, sans degré de liberté, le cylindre 12 à l'intérieur de la porte 2.Under the notch 26 and in the plane 28, the cylinder 12 has a threaded hole 44, extending parallel to the direction Y. This hole 44 receives the screw 14 to fix, without degree of freedom, the cylinder 12 to the inside the door 2.

La figure 3 représente plus en détail l'intérieur du cylindre 12. Le stator 22 comporte un trou cylindrique 50, de section transversale circulaire, traversant de part en part le stator 22 et donc les deux demi-stators 30 et 32. Ce trou 50 s'étend le long de l'axe 20. Ici, l'axe 20 est confondu avec l'axe de symétrie de révolution du trou 50.The figure 3 represents in more detail the interior of the cylinder 12. The stator 22 comprises a cylindrical hole 50, of circular cross section, passing right through the stator 22 and thus the two half-stators 30 and 32. This hole 50 extends along the axis 20. Here, the axis 20 coincides with the axis of symmetry of revolution of the hole 50.

Dans ce texte, par « objet présentant une symétrie de révolution autour d'un axe », on désigne un objet qui est invariant par plus de cinq ou dix symétries de rotation différentes autour de cet axe. Dans le cas particulier du mode de réalisation décrit en référence aux figures, cela désigne un objet qui est invariant par toutes les symétries de rotation possibles autour de cet axe.In this text, the term "object having a symmetry of revolution about an axis" denotes an object that is invariant by more than five or ten different rotational symmetries around this axis. In the particular case of the embodiment described with reference to the figures, this designates an object which is invariant by all possible rotational symmetries around this axis.

Le trou 50 reçoit un rotor 52. Le rotor 52 est décrit plus en détail en référence aux figures 5 et 6. À ses extrémités, le trou 50 débouche dans le cache 34 en vis-à-vis de l'orifice 36.The hole 50 receives a rotor 52. The rotor 52 is described in more detail with reference to the figures 5 and 6 . At its ends, the hole 50 opens into the cover 34 vis-à-vis the orifice 36.

Ici, le demi-stator 32 comporte une coquille 54 entièrement située du côté extérieur du plan 28 et une moitié d'une barrette 56 située du côté extérieur de ce plan 28. La barrette 56 est symétrique par rapport au plan 28. Ainsi, par la suite, seule la moitié de la barrette 56 située du côté extérieur est décrite plus en détail.Here, the half-stator 32 comprises a shell 54 entirely located on the outside of the plane 28 and a half of a bar 56 located on the outside of this plane 28. The bar 56 is symmetrical with respect to the plane 28. Thus, by subsequently, only half of the bar 56 located on the outer side is described in more detail.

La coquille 54 comprend le cache avant 34, l'orifice 36 et la moitié du trou 50 situé du côté extérieur. De préférence, la coquille 54 est formée d'un seul bloc de matière rigide. Par « matière rigide », on désigne une matière dont le module de Young à 25°C est supérieur à 100 GPa ou 150 GPa et, de préférence, supérieur à 200 GPa. Par exemple, la matière rigide est un acier inoxydable.The shell 54 comprises the front cover 34, the orifice 36 and the half of the hole 50 located on the outside. Preferably, the shell 54 is formed of a single block of rigid material. By "rigid material" is meant a material whose Young's modulus at 25 ° C. is greater than 100 GPa or 150 GPa and, preferably, greater than 200 GPa. For example, the rigid material is a stainless steel.

Le trou 50 est par exemple réalisé par alésage à l'intérieur de la coquille 54.The hole 50 is for example made by bore inside the shell 54.

Du côté de l'encoche 26, le diamètre intérieur du trou 50 s'élargit brusquement pour former un épaulement 60 vertical sur lequel un renflement cylindrique 62 (figure 5) du rotor 52 vient en butée pour immobiliser le rotor 52 en translation à l'intérieur du trou 50.On the side of the notch 26, the inside diameter of the hole 50 suddenly widens to form a vertical shoulder 60 on which a cylindrical bulge 62 ( figure 5 ) of the rotor 52 abuts to immobilize the rotor 52 in translation inside the hole 50.

La coquille 54 est séparée de la coquille du demi-stator 30 par un espace formant la partie supérieure de l'encoche 26.The shell 54 is separated from the shell of the half-stator 30 by a space forming the upper part of the notch 26.

La coquille 54 comporte également dans sa partie inférieure un trou borgne 64 débouchant du côté du plan 28. Le trou 64 s'étend parallèlement à la direction X. Ce trou 64 reçoit l'extrémité distale d'une barre horizontale 66 de la barrette 56. La barre 66 est assemblée, sans aucun degré de liberté, à la coquille 54. Par exemple, à cet effet, une goupille 68 traverse, parallèlement à la direction Y la barre 66 et la coquille 54.The shell 54 also has in its lower part a blind hole 64 opening on the side of the plane 28. The hole 64 extends parallel to the direction X. This hole 64 receives the distal end of a horizontal bar 66 of the bar 56 The bar 66 is assembled, without any degree of freedom, to the shell 54. For example, for this purpose, a pin 68 passes parallel, parallel to the direction Y, the bar 66 and the shell 54.

La barre 66 s'étend également de l'autre côté du plan 28. Elle est symétrique par rapport à ce plan 28. La barre 66 permet donc de raccorder mécaniquement, sans aucun degré de liberté, les deux demi-stators 30 et 32 ensemble. Ici, le trou taraudé 44 est réalisé à l'intérieur de cette barre 66.The bar 66 also extends on the other side of the plane 28. It is symmetrical with respect to this plane 28. The bar 66 thus makes it possible to mechanically connect, without any degree of freedom, the two half-stators 30 and 32 together . Here, the tapped hole 44 is made inside this bar 66.

Au niveau du plan 28, la barrette 56 comprend également un pied évidé 70 qui s'étend verticalement depuis la barre 66 jusqu'au rotor 52. Le pied 70 et la barre 66 ne forme qu'un seul bloc de matière. La section verticale de la barrette 56, parallèle au plan X, Z, à la forme d'un « T renversé ». La barre 66 forme la barre horizontale de ce T renversé, et le pied 70 forme le pied de ce T renversé.At the plane 28, the bar 56 also comprises a recessed foot 70 which extends vertically from the bar 66 to the rotor 52. The foot 70 and the bar 66 form a single block of material. The vertical section of the bar 56, parallel to the X, Z plane, has the shape of an "inverted T". The bar 66 forms the horizontal bar of this inverted T, and the foot 70 forms the foot of this inverted T.

Le pied 70 comporte un évidement central 72 formant une partie inférieure de l'encoche 26 pour recevoir le panneton 24. L'extrémité supérieure du pied 70 forme un siège pour supporter le renflement 62 du rotor 52. Ce siège est coupé en deux parties par l'encoche 26, situé, respectivement, de chaque côté du plan 28.The foot 70 has a central recess 72 forming a lower part of the notch 26 to receive the bit 24. The upper end of the foot 70 forms a seat to support the bulge 62 of the rotor 52. This seat is cut in two parts by the notch 26, located respectively on each side of the plane 28.

Le demi-stator 32 comporte également une cavité 74 ménagée à l'intérieur de la coquille 54. Un mécanisme électronique 76 apte à déplacer un organe 80 de blocage de la rotation du rotor 52 est logé à l'intérieur de cette cavité. Par exemple, le mécanisme électronique 76 et l'organe 80 sont similaires ou identiques à ceux décrits dans les demandes de brevets FR2945065 et FR2945308 . Ainsi, seuls les détails nécessaires à la compréhension du fonctionnement du cylindre 12 sont donnés ici. De plus, pour accroître la lisibilité de la figure 3, les représentations du mécanisme électronique 76 et de l'organe 80 ont été simplifiées.The half-stator 32 also comprises a cavity 74 formed inside the shell 54. An electronic mechanism 76 adapted to move a member 80 for blocking the rotation of the rotor 52 is housed inside this cavity. For example, the electronic mechanism 76 and the member 80 are similar or identical to those described in the patent applications FR2945065 and FR2945308 . Thus, only the details necessary for understanding the operation of the cylinder 12 are given here. In addition, to increase the readability of figure 3 the representations of the electronic mechanism 76 and the member 80 have been simplified.

L'organe 80 de blocage se déplace en translation entre une position de blocage (représentée sur la figure 3) et une position escamotée. Dans la position de blocage, une extrémité distale de l'organe 80 est reçue à l'intérieur d'une anfractuosité ménagée dans le rotor 52 pour empêcher la rotation de ce rotor autour de l'axe 20. Dans la position escamotée, l'extrémité distale de l'organe 80 est située en dehors de l'anfractuosité, de sorte que le rotor 52 peut être entraîné en rotation par la clef 16 autour de l'axe 20. Par exemple, l'organe 80 se déplace uniquement en translation entre sa position de blocage et sa position escamotée. Ici, ce déplacement en translation est parallèle à la direction Z.The locking member 80 moves in translation between a locking position (shown in FIG. figure 3 ) and a retracted position. In the locking position, a distal end of the member 80 is received inside an anfractuosity formed in the rotor 52 to prevent the rotation of this rotor about the axis 20. In the retracted position, the distal end of the member 80 is located outside the anfractuosity, so that the rotor 52 can be rotated by the key 16 about the axis 20. For example, the member 80 moves only in translation between its blocking position and its retracted position. Here, this displacement in translation is parallel to the direction Z.

Le mécanisme électronique 76 comporte typiquement un actionneur électrique et/ou magnétique commandable 82 et une unité 84 de commande de cet actionneur 82. L'actionneur 82 est apte à déplacer l'organe 80 entre sa position de blocage et sa position escamotée en réponse à une commande transmise par l'unité 84. En absence de commande, l'actionneur 82 maintient l'organe 80 dans sa position de blocage.The electronic mechanism 76 typically comprises a controllable electric and / or magnetic actuator 82 and a control unit 84 for this actuator 82. The actuator 82 is able to move the member 80 between its blocking position and its retracted position in response to a command transmitted by the unit 84. In the absence of control, the actuator 82 keeps the member 80 in its locking position.

L'unité 84 est apte :

  • à lire le code d'accès contenu dans une clef introduite dans le cylindre 12 aussi bien à partir du côté intérieur que du côté extérieur de ce cylindre 12, puis
  • en fonction du code d'accès lu, à transmettre à l'actionneur 82 une commande de déverrouillage qui déclenche le déplacement de l'organe 80 vers sa position escamotée et, en alternance, à inhiber cette commande pour maintenir l'organe 80 dans sa position de blocage.
Unit 84 is able to:
  • to read the access code contained in a key introduced into the cylinder 12 both from the inside and the outside of this cylinder 12, and then
  • according to the access code read, to transmit to the actuator 82 an unlocking command which triggers the movement of the member 80 to its retracted position and, alternately, to inhibit this command to maintain the member 80 in its blocking position.

Par exemple, l'unité 84 lit le code d'accès transmis par le transpondeur 40 par l'intermédiaire d'une liaison sans fil. Pour autoriser ou, au contraire, inhiber la transmission de la commande de déverrouillage, l'unité 84 compare le code d'accès reçu à des codes d'accès préenregistrés. Si le code d'accès reçu correspond à l'un des codes d'accès préenregistrés, alors l'unité 84 transmet la commande de déverrouillage. Dans le cas contraire, l'unité 84 ne transmet pas cette commande de déverrouillage.For example, the unit 84 reads the access code transmitted by the transponder 40 via a wireless link. To allow or, conversely, inhibit the transmission of the unlock command, the unit 84 compares the access code received with prerecorded access codes. If the access code received corresponds to one of the prerecorded access codes, then the unit 84 transmits the unlock command. Otherwise, the unit 84 does not transmit this unlock command.

Ici, le panneton 24 est monté en rotation autour de l'axe 20 sur le stator 22 et non pas sur le rotor 52. Ainsi, même si le rotor 52 est arraché ou percé, cela a peu d'impacts sur l'intégrité mécanique du panneton 24. À cet effet, chaque demi-stator 30, 32 comporte une face annulaire d'appui. Ces faces annulaires sont symétriques l'une de l'autre par rapport au plan 28. Par conséquent, seule la face annulaire du demi-cylindre 32 va maintenant être décrite en référence à la figure 4.Here, the bit 24 is mounted in rotation about the axis 20 on the stator 22 and not on the rotor 52. Thus, even if the rotor 52 is torn off or pierced, this has little impact on the mechanical integrity 24. For this purpose, each half-stator 30, 32 comprises an annular support face. These annular faces are symmetrical to one another with respect to the plane 28. Therefore, only the annular face of the half-cylinder 32 will now be described with reference to the figure 4 .

Sur la figure 4, pour accroître la lisibilité du dessin, le rotor 52 et le panneton 24 ont été omis. La face annulaire du demi-cylindre 32 porte la référence numérique 86.On the figure 4 to increase the readability of the drawing, the rotor 52 and the bit 24 have been omitted. The annular face of the half-cylinder 32 has the reference numeral 86.

La face annulaire 86 présente une symétrie de révolution autour de l'axe 20. La face annulaire 86 est tournée du côté opposé à l'axe 20 pour former un moyeu autour duquel tourne le panneton 24. Cette face 86 est ici composée d'une rainure circulaire 88 et d'une nervure circulaire 90 immédiatement contiguës dans la direction X. La rainure 88 présente une symétrie de révolution autour de l'axe 20. De même, la nervure 90 présente une symétrie de révolution autour de ce même axe 20. Ici, la rainure 88 et la nervure 90 s'étendent continûment sur 360° autour de l'axe 20.The annular face 86 has a symmetry of revolution about the axis 20. The annular face 86 is turned away from the axis 20 to form a hub around which the bit 24 rotates. This face 86 is here composed of a circular groove 88 and a circular rib 90 immediately contiguous in the direction X. The groove 88 has a symmetry of revolution about the axis 20. Similarly, the rib 90 has a symmetry of revolution about the same axis 20. Here, the groove 88 and the rib 90 extend continuously 360 ° about the axis 20.

La rainure 88 comporte un fond qui regarde du côté opposé à l'axe 20. Ici ce fond est plat et parallèle à l'axe 20. La nervure 90 jouxte immédiatement l'encoche 26. Par exemple, le sommet de la nervure 90 est plat et parallèle à l'axe 20. Le sommet de la nervure 90 regarde lui aussi du côté opposé à l'axe 20.The groove 88 has a bottom facing away from the axis 20. Here this bottom is flat and parallel to the axis 20. The rib 90 immediately adjoins the notch 26. For example, the top of the rib 90 is flat and parallel to the axis 20. The top of the rib 90 is also facing the opposite side to the axis 20.

Ici, la rainure 88 et la nervure 90 sont en partie réalisées dans la coquille 54 et en partie réalisées dans le pied 70 de la barrette 56. Par exemple, plus de 2/3 de la rainure 88 et de la nervure 90 sont réalisées dans la coquille 54 tandis que le reste est réalisé dans le pied 70.Here, the groove 88 and the rib 90 are partly made in the shell 54 and partly formed in the foot 70 of the bar 56. For example, more than 2/3 of the groove 88 and the rib 90 are made in the shell 54 while the rest is made in the foot 70.

Les figures 5 et 6 représentent plus en détail le rotor 52. Le rotor 52 est symétrique par rapport au plan 28. Ainsi, seuls sont décrits les détails du rotor 52 situé d'un côté de ce plan 28. Le rotor 52 comporte le renflement 62. La section transversale de ce renflement 62 est circulaire. Au-delà de ce renflement 62, en allant vers ses extrémités distales, le rotor 52 se prolonge par des cylindres creux 94 de révolution dont le diamètre est strictement inférieur au diamètre extérieur du renflement 62. Ici, les extrémités distales du rotor 52 sont éloignées des caches avants 34. Par exemple, ces extrémités distales sont séparées des caches avants 34 par une distance supérieure à 1 mm ou 5 mm ou 1 cm. Le rotor 52 comporte aussi un canal 96 de clef apte à recevoir l'extrémité de la tige 38 de la clef 16. La section transversale de ce canal 96 comporte au moins une forme complémentaire de l'extrémité de la tige 38 de manière à être engrenée en rotation par la tige 38. Ici, cette forme complémentaire est un méplat 98 apte à s'engrener avec le méplat 42 de la tige 38. Ainsi, lorsque la clef est tournée et que l'organe 80 de blocage est dans sa position escamotée, la rotation de la clef 16 entraîne la rotation du rotor 52.The figures 5 and 6 The rotor 52 is symmetrical with respect to the plane 28. Thus, only the details of the rotor 52 located on one side of this plane 28 are described. The rotor 52 comprises the bulge 62. The cross section this bulge 62 is circular. Beyond this bulge 62, towards its distal ends, the rotor 52 is extended by hollow cylinders 94 of revolution, whose diameter is strictly less than the outside diameter of the bulge 62. Here, the distal ends of the rotor 52 are remote from the front covers 34. For example, these distal ends are separated from the front covers 34 by a distance greater than 1 mm or 5 mm. mm or 1 cm. The rotor 52 also comprises a key channel 96 adapted to receive the end of the rod 38 of the key 16. The cross section of this channel 96 comprises at least one complementary shape of the end of the rod 38 so as to be rotated by the rod 38. Here, this complementary shape is a flat 98 capable of meshing with the flat portion 42 of the rod 38. Thus, when the key is turned and the locking member 80 is in its position retracted, the rotation of the key 16 causes the rotor 52 to rotate.

Le rotor 52 comprend également une collerette 100 qui fait saillie depuis le renflement 62. La collerette 100 s'étend dans le plan 28 et à l'intérieur de l'encoche 26. Cette collerette 100 est coincée entre les deux demi-stators 30 et 32 (figure 3). La face radiale de cette collerette est dépourvue de symétrie de rotation autour de l'axe 20. À cet effet, la face radiale de la collerette 100 comporte deux méplats 102 et 104. Les méplats 102 et 104 s'étendent chacun dans des plans respectifs faisant un angle aigu compris entre 10° et 80° et, de préférence, entre 30° et 80°. Ces méplats 102, 104 servent à entraîner en rotation le panneton 24.The rotor 52 also comprises a flange 100 which protrudes from the bulge 62. The flange 100 extends in the plane 28 and inside the notch 26. This flange 100 is wedged between the two half-stators 30 and 32 ( figure 3 ). The radial face of this flange is devoid of symmetry of rotation about the axis 20. For this purpose, the radial face of the flange 100 comprises two flats 102 and 104. The flats 102 and 104 each extend in respective planes. making an acute angle between 10 ° and 80 ° and preferably between 30 ° and 80 °. These flats 102, 104 serve to rotate the bit 24.

Les figures 7 et 8 représentent plus en détail le panneton 24. Pour simplifier ces figures, le stator 22 a été omis.The Figures 7 and 8 24. In order to simplify these figures, the stator 22 has been omitted.

Le panneton 24 comporte :

  • une bague 110 qui enserre le rotor 52 et les deux demi-stators 30 et 32 dans sa position fermée (représentée sur la figure 7), et
  • un bras 112 qui s'engrène avec le pêne 10 pour le déplacer entre ses positions verrouillée et déverrouillée.
The bit 24 comprises:
  • a ring 110 which encloses the rotor 52 and the two half-stators 30 and 32 in its closed position (shown in FIG. figure 7 ), and
  • an arm 112 which meshes with the bolt 10 to move it between its locked and unlocked positions.

La bague 110 comporte une face interne 114 tournée vers l'axe 20, et une face externe 116 située du côté opposé. La face interne 114 est décrite plus en détail en référence des figures 9 et 10.The ring 110 has an internal face 114 facing the axis 20, and an outer face 116 located on the opposite side. The inner face 114 is described in more detail with reference to Figures 9 and 10 .

La face externe 116 est cylindrique et présente une symétrie de révolution autour de l'axe 20. Le bras 112 s'étend radialement depuis cette face externe 116 en s'éloignant de l'axe 20.The outer face 116 is cylindrical and has a symmetry of revolution about the axis 20. The arm 112 extends radially from this outer face 116 away from the axis 20.

Le panneton 24 comporte également une charnière 118 et un interstice 120 qui le divise en deux demi-pannetons 122 et 124, articulés l'un par rapport à l'autre.The bit 24 also comprises a hinge 118 and a gap 120 which divides it into two half-bells 122 and 124, hinged relative to each other.

La charnière 118 est située sur la bague 110. L'axe 126 de rotation de cette charnière 118 est parallèle à l'axe 20. La charnière 118 permet de déplacer le demi-panneton 122 par rapport au demi-panneton 124 en rotation autour de l'axe 126, entre la position fermée (représentée sur la figure 7) et une position ouverte (représentée sur la figure 8). Dans la position ouverte, le rotor 52 et les faces annulaires 86 du stator 22 peuvent être insérés à l'intérieur de la bague 110. Dans sa position fermée, le panneton 24 est fixé sans aucun degré de liberté en rotation sur le rotor 52 et attache mécaniquement les deux demi-stators 30 et 32.The hinge 118 is located on the ring 110. The axis 126 of rotation of this hinge 118 is parallel to the axis 20. The hinge 118 moves the half-bit 122 relative to the half-bit 124 in rotation around the axis 126, between the closed position (represented on the figure 7 ) and an open position (shown on the figure 8 ). In the open position, the rotor 52 and the annular faces 86 of the stator 22 can be inserted inside the ring 110. closed position, the bit 24 is fixed without any degree of freedom in rotation on the rotor 52 and mechanically attaches the two half-stators 30 and 32.

Ici, l'interstice 120 s'étend radialement dans un plan longitudinal 127 contenant l'axe 20 et traversant de part en part la bague 110 et le milieu du bras 112. Ici, l'interstice 120 est diamétralement opposé à l'axe 126 par rapport à l'axe 20.Here, the gap 120 extends radially in a longitudinal plane 127 containing the axis 20 and passes right through the ring 110 and the middle of the arm 112. Here, the gap 120 is diametrically opposite to the axis 126. with respect to the axis 20.

Pour verrouiller le panneton 24 dans sa position fermée, le bras 112 est traversé par un trou 128 dans une direction perpendiculaire au plan 127. Le trou 128 reçoit un rivet 130 (figure 11) ou un boulon ou une vis pour verrouiller le panneton 24 dans sa position fermée.To lock the bit 24 in its closed position, the arm 112 is traversed by a hole 128 in a direction perpendicular to the plane 127. The hole 128 receives a rivet 130 ( figure 11 ) or a bolt or screw to lock the bit 24 in its closed position.

Les figures 9 et 10 représentent plus en détail la face interne 114 de la bague 110. Sur la figure 9, seul le demi-panneton 124 est représenté pour rendre la face interne 114 plus visible. Pour les mêmes raisons, les demi-pannetons 122 et 124 sont représentés en vue éclatée sur la figure 10.The Figures 9 and 10 show in more detail the internal face 114 of the ring 110. On the figure 9 only the half-bit 124 is shown to make the inner face 114 more visible. For the same reasons, the half-bibs 122 and 124 are represented in exploded view on the figure 10 .

La face interne 114 est symétrique par rapport au plan 127 dans la position fermée du panneton 24. Ainsi, seule la description de la face interne située d'un seul côté de ce plan 127 est donnée par la suite. De même, la face interne 114 est symétrique par rapport au plan 28.The inner face 114 is symmetrical with respect to the plane 127 in the closed position of the blade 24. Thus, only the description of the inner face located on one side of this plane 127 is given later. Similarly, the inner face 114 is symmetrical with respect to the plane 28.

La face interne 114 comporte deux faces annulaires 132 et 134 destinées à venir directement en appui, respectivement, sur les faces annulaires correspondantes du stator 22 pour former une liaison pivot permettant au panneton 24 de tourner autour de l'axe 20. Les faces annulaires 132 et 134 sont symétriques par rapport au plan 28. Ainsi, seule la face annulaire 132 est décrite plus en détail.The inner face 114 has two annular faces 132 and 134 intended to bear directly, respectively, on the corresponding annular faces of the stator 22 to form a pivot connection allowing the blade 24 to rotate about the axis 20. The annular faces 132 and 134 are symmetrical with respect to the plane 28. Thus, only the annular face 132 is described in more detail.

La face annulaire 132 a une forme complémentaire de la face annulaire 86 du demi-stator 32. Elle comprend donc :

  • une nervure 138 destinée à être reçue à l'intérieur de la rainure 88, et
  • une rainure 140 recevant la nervure 90.
The annular face 132 has a shape complementary to the annular face 86 of the half-stator 32. It therefore comprises:
  • a rib 138 intended to be received inside the groove 88, and
  • a groove 140 receiving the rib 90.

La nervure 138 fait saillie vers l'axe 20. Elle est circulaire. Ici, elle s'étend continûment sur 360° autour de l'axe 20. Le sommet de la nervure 138 est plat pour venir en appui glissant sur le fond plat de la rainure 88.The rib 138 projects towards the axis 20. It is circular. Here, it extends continuously 360 ° about the axis 20. The top of the rib 138 is flat to come slidingly against the flat bottom of the groove 88.

La rainure 140 s'étend continûment sur 360° autour de l'axe 20. Son fond est plat pour venir en appui glissant sur le sommet plat de la nervure 90.The groove 140 extends continuously 360 ° about the axis 20. Its bottom is flat to come sliding on the flat top of the rib 90.

La coopération de forme entre la rainure 88 et la nervure 138 permet non seulement de monter en rotation le panneton 124 sur le stator 22, mais aussi de maintenir assemblé l'un à l'autre les deux demi-stators 30 et 32.The shape cooperation between the groove 88 and the rib 138 makes it possible not only to rotate the bit 124 on the stator 22, but also to hold the two half-stators 30 and 32 together.

La face interne 114 comporte aussi, dans le plan 28, une face radiale complémentaire de la face radiale de la collerette 100. Cette face radiale vient directement en appui sur la face radiale de la collerette 100 pour fixer en permanence et sans aucun degré de liberté en rotation, le panneton 24 sur le rotor 52 tant que le panneton 24 est dans sa position fermée. Ici, la face radiale du panneton comporte des méplats aptes à établir une coopération de forme avec, respectivement, les méplats 102 et 104. Seul un méplat 144 de cette face radiale est visible sur les figures 9 et 10. Ce méplat 144 s'étend dans un plan parallèle au plan dans lequel s'étend le méplat 104. Il est positionné pour venir directement en appui sur le méplat 104 lorsque le panneton 24 est dans sa position fermée.The internal face 114 also comprises, in the plane 28, a radial face complementary to the radial face of the flange 100. This radial face bears directly on the radial face of the flange 100 to fix permanently and without any degree of freedom in rotation, the bit 24 on the rotor 52 as the bit 24 is in its closed position. Here, the radial face of the bit comprises flats able to establish a shape cooperation with, respectively, the flats 102 and 104. Only a flat portion 144 of this radial face is visible on the Figures 9 and 10 . This flat portion 144 extends in a plane parallel to the plane in which the flattened surface 104 extends. It is positioned to bear directly on the flat surface 104 when the bit 24 is in its closed position.

La figure 11 illustre l'assemblage du cylindre 12. Tout d'abord, la barrette 56 et le demi-cylindre 30 sont assemblés. Ensuite, le rotor 52 est introduit dans le trou 50 du demi-stator 30. La coquille 54 est alors assemblée sur la barrette 56 et vient coincer le rotor 52 entre les deux coquilles du stator 22.The figure 11 illustrates the assembly of the cylinder 12. First, the bar 56 and the half-cylinder 30 are assembled. Then, the rotor 52 is introduced into the hole 50 of the half-stator 30. The shell 54 is then assembled on the bar 56 and jams the rotor 52 between the two shells of the stator 22.

Le panneton 24, dans sa position ouverte, est alors introduit dans l'encoche 26 autour du rotor 52 et en vis-à-vis des faces annulaires du stator 22. Ensuite, le panneton 24 est déplacé vers sa position fermée pour enserrer le rotor 52 et s'emboîter dans la rainure 88. Enfin, le rivet 130 est monté pour verrouiller le panneton 24 dans sa position fermée.The bit 24, in its open position, is then introduced into the notch 26 around the rotor 52 and opposite the annular faces of the stator 22. Then, the bit 24 is moved to its closed position to grip the rotor 52 and snap into the groove 88. Finally, the rivet 130 is mounted to lock the blade 24 in its closed position.

Le fonctionnement du cylindre 12 est le suivant. Pour décrire ce fonctionnement, on suppose que la clef 16 est une clef autorisée. La tige 38 de la clef 16 est introduite dans l'orifice 36 et poussée horizontalement jusqu'à ce que son extrémité s'engage à l'intérieur du canal 96. Le code d'accès de la clef 16 est alors transmis au mécanisme électronique 76. En réponse, le mécanisme électronique 76 déplace l'organe 80 vers sa position escamotée. L'utilisateur tourne alors la clef 16. Le méplat 42 de la tige 38 de la clef 16 s'engrène alors avec le méplat 98 du canal 96 de clef. Le rotor 52 tourne alors autour de l'axe 20 entraînant en même temps le panneton 24 en rotation. Cette rotation du panneton 24 déverrouille la serrure 6. Le fonctionnement est le même quel que soit le côté par lequel est introduit la clef 16.The operation of the cylinder 12 is as follows. To describe this operation, it is assumed that the key 16 is an authorized key. The rod 38 of the key 16 is inserted into the orifice 36 and pushed horizontally until its end engages inside the channel 96. The access code of the key 16 is then transmitted to the electronic mechanism In response, the electronic mechanism 76 moves the member 80 to its retracted position. The user then turns the key 16. The flat portion 42 of the shank 38 of the key 16 then meshes with the flat portion 98 of the key channel 96. The rotor 52 then rotates about the axis 20 driving at the same time the bit 24 in rotation. This rotation of the bit 24 unlocks the lock 6. The operation is the same regardless of which side is introduced by the key 16.

De nombreux autres modes de réalisation sont possibles. Par exemple, une seule paire de rainure/nervure est utilisée pour monter en rotation le panneton sur le stator. Dans une autre variante, la rainure 88, la nervure 90, la nervure 138 et la rainure 140 sont omises. Dans cette variante, les faces annulaires sont des cylindres de révolution dont l'axe de révolution est confondu avec l'axe 20. Les faces annulaires servent donc dans cette variante uniquement à établir une liaison pivot entre le panneton et le stator et non plus à attacher entre eux les deux demi-stators 30, 32. Dans ce dernier cas, la fixation des deux demi-stators 30, 32 ensemble est assurée autrement, par exemple, seulement par la barre 66 de liaison ou par d'autres moyens.Many other embodiments are possible. For example, a single pair of groove / rib is used to rotate the bit on the stator. In another variant, the groove 88, the rib 90, the rib 138 and the groove 140 are omitted. In this variant, the annular faces are cylinders of revolution whose axis of revolution coincides with the axis 20. The annular faces thus serve in this variant only to establish a pivot connection between the bit and the stator and no longer to the two half-stators 30, 32 are attached between them. In the latter case, the two half-stators 30, 32 are secured together, for example, only by the connecting bar 66 or by other means.

Les formes complémentaires de la face radiale du panneton destinée à coopérer avec la face radiale de la collerette peuvent être aussi réalisées non pas en relief, mais en creux. D'autres formes sont également possibles pour la face radiale de la collerette 100. Par exemple, en variante, cette collerette comporte un seul méplat ou plus de deux méplats.The complementary shapes of the radial face of the bit intended to cooperate with the radial face of the flange may also be made not in relief, but hollow. Other forms are also possible for the radial face of the collar 100. For example, alternatively, this flange comprises a single flat or more than two flats.

Dans une autre variante, le cache avant 34 est omis. Dans ce cas, l'extrémité distale du rotor est directement exposée à l'extérieur du cylindre.In another variant, the front cover 34 is omitted. In this case, the distal end of the rotor is directly exposed to the outside of the cylinder.

Le plan 28 n'est pas nécessairement un plan de symétrie pour le rotor et n'est pas nécessairement situé au milieu du stator. Par exemple, en variante, l'un des demi-stators est plus long que l'autre dans la direction X. Toutefois, ce qui a été décrit précédemment peut facilement être adapté à cette situation où le plan 28 n'est pas au milieu.The plane 28 is not necessarily a plane of symmetry for the rotor and is not necessarily located in the middle of the stator. For example, as a variant, one of the half-stators is longer than the other in the X direction. However, what has been described above can easily be adapted to this situation where the plane 28 is not in the middle. .

Le stator 22 peut être réalisé différemment. Par exemple, chaque moitié de la barrette 56 ne forme qu'un seul bloc de matière avec la coquille située du même côté. Dans ce cas, les demi-cylindres sont formés chacun d'une seule coquille assemblée, sans aucun degré de liberté, l'une à l'autre, par des vis ou goupilles s'étendant parallèlement à la direction X. La barrette 56 n'existe alors plus en tant que pièce indépendante.The stator 22 can be made differently. For example, each half of the bar 56 forms a single block of material with the shell on the same side. In this case, the half-cylinders are each formed of a single assembled shell, without any degree of freedom, one to the other, by screws or pins extending parallel to the direction X. The bar 56 n 'then exists more as an independent piece.

La lecture du transpondeur 40 par l'unité 84 peut aussi être réalisée par l'intermédiaire d'une liaison filaire.The reading of the transponder 40 by the unit 84 can also be performed via a wire link.

Il n'est pas nécessaire que la nervure 138 s'étende continûment sur 360° autour de l'axe 20. En variante, elle ne s'étend pas continûment sur 360° autour de l'axe 20.It is not necessary for the rib 138 to extend continuously 360 ° about the axis 20. In a variant, it does not extend continuously 360 ° about the axis 20.

Le cylindre décrit ici peut facilement être adapté au cas d'un cylindre de serrure dans lesquels la clé peut seulement être introduite dans le cylindre depuis le côté extérieur. Par exemple, dans ce cas, l'orifice 36 du cylindre situé du côté intérieur est omis.The cylinder described here can easily be adapted to the case of a lock cylinder in which the key can only be inserted into the cylinder from the outside. For example, in this case, the hole 36 of the cylinder located on the inner side is omitted.
