Description

L'invention a pour objet un verrou du type comportant un stator et un rotor monté dans ledit stator, ledit stator étant muni d'un logement destiné à recevoir une clé adaptée à coopérer avec des éléments de condamnation prévus pour verrouiller ledit rotor par rapport audit stator lorsque la clé n'est pas présente dans ledit logement, et rendre libre le rotor de tourner par rapport audit stator lorsque la clé est présente dans ledit logement.The subject of the invention is a lock of the type comprising a stator and a rotor mounted in said stator, said stator being provided with a housing intended to receive a key adapted to cooperate with locking elements provided for locking said rotor with respect to said stator when the key is not present in said housing, and making the rotor free to rotate relative to said stator when the key is present in said housing.

Jusqu'ici, un tel verrou a été réalisé de différentes manières dans le but d'obtenir de nombreuses variations ou combinaisons de clés et de rotors associés.So far, such a lock has been produced in different ways in order to obtain numerous variations or combinations of keys and associated rotors.

On connaît des clés plates, à section rectangulaire, dont des indentations prévues sur la tranche de la clé ont des profondeurs et un positionnement sur la tranche variés pour obtenir différentes combinaisons : si la fabrication d'une telle clé est aisée et peu coûteuse, le nombre de combinaisons est réduit.Flat keys are known, with rectangular section, of which indentations provided on the edge of the key have varying depths and positioning on the edge to obtain different combinations: if the manufacture of such a key is easy and inexpensive, the number of combinations is reduced.

Pour augmenter le nombre de combinaisons, on a déjà réalisé des clés en forme de cylindre à la périphérie duquel sont ménagés des logements, destinés à recevoir les éléments de condamnation, répartis longitudinalement et angulairement ; ces logements ne communiquant pas entre eux ont rendu difficile l'obtention d'une telle clé par des moyens de fabrication limitant le prix de revient, une telle clé étant nécessairement obtenue par matriçage.To increase the number of combinations, keys have already been made in the form of a cylinder at the periphery of which are housed, intended to receive the locking elements, distributed longitudinally and angularly; these housings which do not communicate with each other have made it difficult to obtain such a key by manufacturing means limiting the cost price, such a key being necessarily obtained by stamping.

La présente invention a pour objet un verrou du type ci-dessus dont les combinaisons de clés sont nombreuses et dont la fabrication est aisée, donc peu onéreuse.The present invention relates to a lock of the above type whose key combinations are numerous and whose manufacture is easy, therefore inexpensive.

Ainsi, selon l'invention, un verrou comportant un stator et un rotor monté dans ledit stator, ledit rotor étant muni d'un logement destiné à recevoir une clé adaptée à coopérer avec des éléments de condamnation prévus pour verrouiller ledit rotor par rapport audit stator lorsque la clé n'est pas présente dans ledit logement, et rendre libre le rotor de tourner par rapport audit stator lorsque la clé est présente dans ledit logement, est caractérisé par le fait que le logement du rotor est un alesage axial cylindrique de section non circulaire dans lequel s'étendent les éléments de condamnation dont au moins deux d'entre eux sont dans un même plan perpendiculaire à l'axe commun au rotor et au stator, ladite clé étant creusée d'une gorge périphérique circonférencielle limitée intérieurement par un fond avec lequel les au moins deux éléments de condamnation sont amenés à coopérer lorsque la clé est présente dans le logement du rotor.Thus, according to the invention, a lock comprising a stator and a rotor mounted in said stator, said rotor being provided with a housing intended to receive a key adapted to cooperate with locking elements provided for locking said rotor relative to said stator when the key is not present in said housing, and making the rotor free to rotate relative to said stator when the key is present in said housing, is characterized by the fact that the rotor housing is a cylindrical axial bore of non-cross section circular in which the locking elements extend, at least two of which are in the same plane perpendicular to the axis common to rotor and stator, said key being hollowed out by a circumferential peripheral groove internally limited by a bottom with which the at least two locking elements are brought to cooperate when the key is present in the housing of the rotor.

Grâce à cette disposition, la gorge peut être réalisée par des moyens simples d'usinage, et être taillée par tournage, ce qui minimise le prix de revient de l'ensemble du verrou et de la clé qui lui est associée.Thanks to this arrangement, the groove can be produced by simple machining means, and be cut by turning, which minimizes the cost price of the assembly of the bolt and of the key associated therewith.

Avantageusement, la section de l'alesage du rotor est, selon un premier secteur, un arc de cercle centré sur l'axe du rotor s'étendant sur moins de 360° et, selon un deuxième secteur, de forme quelconque différente d'un arc de cercle selon le cercle du premier secteur (106).Advantageously, the section of the rotor bore is, according to a first sector, a circular arc centered on the axis of the rotor extending over less than 360 ° and, according to a second sector, of any shape other than a arc of a circle along the circle of the first sector (106).

En variante, la section de l'alesage du rotor est formée de deux secteurs circulaires appartenant à un même cercle centré sur l'axe du rotor, et de deux plats.As a variant, the section of the rotor bore is formed by two circular sectors belonging to the same circle centered on the axis of the rotor, and by two flats.

De préférence, les deux plats se font face, les deux secteurs circulaires se faisant également face.Preferably, the two dishes face each other, the two circular sectors also facing each other.

Avantageusement, le fond de la gorge est de section circulaire et son axe est distinct de l'axe du rotor ; en variante, le fond de la gorge est elliptique, l'ellipse ayant son centre sur l'axe du rotor.Advantageously, the bottom of the groove is of circular section and its axis is distinct from the axis of the rotor; alternatively, the bottom of the groove is elliptical, the ellipse having its center on the axis of the rotor.

Les éléments de condamnation sont constitués de goupilles de stator et de goupilles de rotor montées coulissantes dans des perçages radiaux du stator et du rotor.The locking elements consist of stator pins and rotor pins slidably mounted in radial holes in the stator and the rotor.

On appréciera qu'un tel verrou est de fabrication peu onéreuse et permet de nombreuses combinaisons ; en outre, il est de longueur axiale faible et sa protection, en particulier à l'égard de l'eau ou de la poussière, peut être réalisée facilement ; pour cela, il suffit de monter un élément protecteur coulissant dans le logement de clé, ledit élément protecteur présentant une face de fermeture venant fermer le logement lorsque la clé n'est pas présente dans le logement, sous l'action de moyens élastiques agissant sur ledit élément protecteur.It will be appreciated that such a lock is inexpensive to manufacture and allows many combinations; furthermore, it has a short axial length and its protection, in particular with regard to water or dust, can be easily achieved; for this, it suffices to mount a sliding protective element in the key housing, said protective element having a closing face closing the housing when the key is not present in the housing, under the action of elastic means acting on said protective element.

L'invention a également pour objet une clé destinée à être utilisée dans un verrou tel que défini ci-dessus pour le verrouillage et le déverrouillage du rotor et du stator dudit verrou.The invention also relates to a key intended to be used in a lock as defined above for locking and unlocking the rotor and the stator of said lock.

L'élément protecteur ci-dessus est également applicable à tout verrou du type comportant un stator et un rotor monté dans ledit stator, ledit rotor étant muni d'un logement destiné à recevoir une clé adaptée à coopérer avec des éléments de condamnation prévus pour verrouiller ledit rotor par rapport audit stator lorsque la clé n'est pas présente dans ledit logement, et rendre libre le rotor de tourner par rapport audit stator lorsque la clé est présente dans ledit logement.The above protective element is also applicable to any lock of the type comprising a stator and a rotor mounted in said stator, said rotor being provided with a housing intended to receive a key adapted to cooperate with locking elements provided for locking. said rotor relative to said stator when the key is not present in said housing, and making the rotor free to rotate relative to said stator when the key is present in said housing.

Il est utile de protéger le verrou, et en particulier ses éléments de condamnation, à l'égard de l'eau et de la poussière, par exemple lorsque le verrou est monté sur un véhicule automobile.It is useful to protect the lock, and in particular its locking elements, against water and dust, for example when the lock is mounted on a motor vehicle.

On a déjà équipé des verrous d'éléments de protection, mais jusqu'ici ces éléments de protection sont peu fiables et/ou encombrants ; en particulier dans l'application à un véhicule automobile, les verrous sont souvent de taille très réduite et il est difficile de les équiper d'un élément protecteur efficace.Locks have already been fitted with protective elements, but so far these protective elements are unreliable and / or bulky; in particular in the application to a motor vehicle, the locks are often very small in size and it is difficult to equip them with an effective protective element.

La présente invention résoud ce problème.The present invention solves this problem.

Ainsi, selon l'invention, un verrou du type ci-dessus est caractérisé par le fait qu'un élément protecteur est monté coulissant dans ledit logement de clé, ledit élément protecteur présentant une face de fermeture venant fermer le logement, lorsque la clé n'est pas présente dans le logement, sous l'action de moyens élastiques agissant sur ledit élément protecteur ; la section de l'élément protecteur est égale à celle du logement, au jeu de montage près ; la section du logement est d'une forme telle qu'elle permet l'entraînement en rotation du rotor par la clé.Thus, according to the invention, a lock of the above type is characterized in that a protective element is slidably mounted in said key housing, said protective element having a closing face closing the housing, when the key n 'is not present in the housing, under the action of elastic means acting on said protective element; the section of the protective element is equal to that of the housing, apart from the mounting clearance; the section of the housing is of a shape such that it allows the rotor to be driven in rotation by the key.

Avantageusement, les moyens élastiques agissant sur ledit élément protecteur prennent appui sur un bouchon fermant l'extrémité du logement opposée à celle qui permet l'introduction de la clé dans le logement.Advantageously, the elastic means acting on said protective element bear on a plug closing the end of the housing opposite to that which allows the introduction of the key into the housing.

Selon une forme préférée de réalisation, la face de fermeture est entourée par une plaque d'entrée solidaire du rotor ; la face extérieure de la plaque d'entrée a une forme facilitant l'introduction de la clé dans le logement.According to a preferred embodiment, the closing face is surrounded by an inlet plate integral with the rotor; the outer face of the entry plate has a shape facilitating the introduction of the key into the housing.

De préférence, les éléments de condamnation sont constitués de goupilles disposées dans des passages radiaux ménagés radialement dans le stator et le rotor.Preferably, the locking elements consist of pins arranged in radial passages formed radially in the stator and the rotor.

Pour mieux faire comprendre l'objet de l'invention, on va en décrire, maintenant, à titre d'exemple purement illustratif et non limitatif, un mode de réalisation représenté sur le dessin annexé.To better understand the object of the invention, we will now describe, by way of purely illustrative and nonlimiting example, an embodiment shown in the accompanying drawing.

  • Figures 2 and 3 show, in cross section, two variants of a lock according to the invention, the key being present in the rotor and the cut being made in line with a groove that the key has.

Selon la figure 1, un verrou, par exemple de porte de véhicule automobile, comprend un stator 10 dans lequel est monté tournant un rotor 12 ; le stator 10 est percé d'un alésage cylindrique de révolution 11 débouchant d'un côté à l'extérieur et prolongé de l'autre côté par un alésage cylindrique de révolution 13 de plus petit diamètre que l'alésage 11, en sorte qu'entre les deux alésages est définie une portée annulaire 14 transversale. Le rotor 12 comporte une première portion cylindrique de révolution 15 dont le diamètre extérieur est égal, au jeu de montage près, à celui de l'alésage 11 du stator 10, et une deuxième portion cylindrique de révolution 16 dont le diamètre extérieur est égal, au jeu de montage près, à celui de l'alésage 13 du stator 10. Les deux portions 15 et 16 sont raccordées par une portée 17 annulaire transversale. La longueur de la première portion 15 est égale à la longueur de l'alésage 11, tandis que la longueur de la deuxième portion 16 est supérieure à la longueur de l'alésage 13. Lorsque le rotor 12 est monté dans le stator 10, les faces d'extrémité transversales 18 et 19 qui bordent respectivement l'alésage 11 du stator 10 et la première portion 15 du rotor 12 sont dans un même plan perpendiculaire à l'axe commun du stator 10 et du rotor 12 ; dans cette position, les portées 14 et 17 transversales coopèrent en butée et la portion 16 du rotor dépasse axialement du stator 10 ; sur la portion 16 du rotor 12 qui dépasse est montée une batteuse 20 adaptée à actionner des moyens de fermeture de la porte, non représentés, de manière habituelle, la batteuse 20 étant solidaire en rotation du rotor 12 au moyen, par exemple, de méplats complémentaires, non représentés, portés respectivement par la portion 16 du rotor 12 et par le logement 21 de la batteuse 20 par lequel elle est montée sur la portion 16 du rotor 12 ; une gorge 22 ménagée à la périphérie de la portion 16 reçoit un jonc 23 qui arrête axialement la batteuse 20 par rapport à la portion 16 du rotor 12 ; la batteuse 20 coopérant, du côté opposé au jonc 23, avec la face 24 transversale du stator 10 qui borde l'alésage 13 du stator 10, le rotor 12 se trouve arrêté axialement par rapport au stator 10.According to Figure 1, a lock, for example of a motor vehicle door, comprises a stator 10 in which is rotatably mounted a rotor 12; the stator 10 is pierced with a cylindrical bore of revolution 11 opening on one side to the outside and extended on the other side by a cylindrical bore of revolution 13 of smaller diameter than the bore 11, so that between the two bores is defined a transverse annular bearing 14. The rotor 12 includes a first cylindrical portion of revolution 15 whose outside diameter is equal, apart from the mounting clearance, to that of the bore 11 of the stator 10, and a second cylindrical portion of revolution 16 whose outside diameter is equal, apart from the mounting clearance, that of the bore 13 of the stator 10. The two portions 15 and 16 are connected by a transverse annular bearing 17. The length of the first portion 15 is equal to the length of the bore 11, while the length of the second portion 16 is greater than the length of the bore 13. When the rotor 12 is mounted in the stator 10, the transverse end faces 18 and 19 which respectively line the bore 11 of the stator 10 and the first portion 15 of the rotor 12 are in the same plane perpendicular to the common axis of the stator 10 and the rotor 12; in this position, the transverse bearing surfaces 14 and 17 cooperate in abutment and the portion 16 of the rotor protrudes axially from the stator 10; on the portion 16 of the rotor 12 which protrudes is mounted a thresher 20 adapted to actuate means for closing the door, not shown, in the usual way, the thresher 20 being integral in rotation with the rotor 12 by means, for example, of flats complementary, not shown, carried respectively by the portion 16 of the rotor 12 and by the housing 21 of the threshing machine 20 by which it is mounted on the portion 16 of the rotor 12; a groove 22 formed at the periphery of the portion 16 receives a rod 23 which axially stops the threshing machine 20 relative to the portion 16 of the rotor 12; the threshing machine 20 cooperating, on the side opposite the rod 23, with the transverse face 24 of the stator 10 which borders the bore 13 of the stator 10, the rotor 12 is stopped axially with respect to the stator 10.

Le rotor 12 est traversé axialement par un logement 25 destiné à recevoir une clé ; des éléments de condamnation 26 sont prévus pour verrouiller le rotor 12 par rapport au stator 10 lorsque la clé n'est pas présente dans le logement 25, et rendre libre le rotor 12 de tourner par rapport au stator 10 lorsque la clé est présente dans le logement 25 ; les éléments de condamnation 26 sont constitués de goupilles disposées disposées par paires 27A, 27B dans des passages radiaux ménagés transversalement dans l'épaisseur du stator 10 et du rotor 12 qu'ils traversent complètement en débouchant dans le logement 25 ; des ressorts 28, prenant appui sur des pastilles 29 rapportées fermant lesdits passages radiaux à la périphérie extérieure du stator 10, sollicitent les goupilles vers le logement 25 ; les goupilles sont de longueurs différentes ; la clé porte des indentations de profondeurs différentes adaptées aux goupilles, en sorte que lorsque la clé est dans le logement 25 les indentations de la clé coopèrent avec les goupilles 27B de manière que l'extrémité supérieure, par rapport à la figure, de toutes les goupilles 27B affleurent toutes la portion cylindrique 15 du rotor 12, lequel peut alors tourner dans le stator 10 lorsqu'un mouvement de rotation est donné à la clé, entraînant la batteuse 20 ; lorsque la clé n'est pas présente dans le logement 25, les goupilles sont en partie dans le rotor 12 et en partie dans le stator 10, ce qui empêche toute rotation du rotor 12 par rapport au stator 10.The rotor 12 is axially traversed by a housing 25 intended to receive a key; locking elements 26 are provided for locking the rotor 12 relative to the stator 10 when the key is not present in the housing 25, and making the rotor 12 free to rotate relative to the stator 10 when the key is present in the housing 25; the locking elements 26 consist of pins arranged arranged in pairs 27A, 27B in radial passages formed transversely in the thickness of the stator 10 and the rotor 12 which they pass completely through opening into the housing 25; springs 28, bearing on added pads 29 closing said radial passages at the outer periphery of the stator 10, urge the pins towards the housing 25; the pins are of different lengths; the key carries indentations of different depths adapted to the pins, so that when the key is in the housing 25 the indentations of the key cooperate with the pins 27B so that the upper end, relative to the figure, of all pins 27B are all flush with the cylindrical portion 15 of the rotor 12, which can then rotate in the stator 10 when a rotary movement is given to the key, driving the thresher 20; when the key is not present in the housing 25, the pins are partly in the rotor 12 and partly in the stator 10, which prevents any rotation of the rotor 12 relative to the stator 10.

Dans le logement 25 de clé, est monté coulissant un élément protecteur 30 ayant la même section que celle du logement 25, au jeu de montage près, cette section étant par exemple de forme rectangulaire ; l'élément protecteur 30 présente une face de fermeture 31, sphérique concave transversale, limitant d'un côté un espace axial 32 recevant un ressort 33 prenant appui, d'un côté, sur la paroi de la face 31 et, de l'autre côté, sur un bouchon 34 fermant l'extrémité du logement 25 de clé.In the key housing 25, there is slidably mounted a protective element 30 having the same section as that of the housing 25, apart from the mounting clearance, this section being for example of rectangular shape; the protective element 30 has a closing face 31, spherical concave transverse, limiting on one side an axial space 32 receiving a spring 33 bearing, on one side, on the wall of the face 31 and, on the other side, on a plug 34 closing the end of the key housing 25.

Une plaque d'entrée 35 entoure la face de fermeture 31 et recouvre la face d'extrémité transversale 19 du rotor 12 et, partiellement, la face d'extrémité transversale 18 du stator 10 qui est prolongée par une face annulaire 36 axialement décalée vers l'extérieur et définissant un logement 37 pour la plaque 35 solidarisée au rotor 15, par des moyens non représentés. La face externe 38 de la plaque 35 est sphérique concave et prolonge la face 31 de l'élément protecteur 30, lorsque l'élément protecteur 30 est dans la position représentée sur la figure 1 pour laquelle l'élément protecteur 30 ferme l'entrée du logement 25 de clé ; dans cette position, sous l'action du ressort 33, l'élément protecteur 30 est en butée grâce à un ergot qu'il porte, non représenté, et qui coopère avec une butée prévue dans le logement 25, également non représentée.An entry plate 35 surrounds the closing face 31 and covers the transverse end face 19 of the rotor 12 and, partially, the transverse end face 18 of the stator 10 which is extended by an annular face 36 axially offset towards the exterior and defining a housing 37 for the plate 35 secured to the rotor 15, by means not shown. The external face 38 of the plate 35 is spherical concave and extends the face 31 of the protective element 30, when the protective element 30 is in the position shown in FIG. 1 for which the protective element 30 closes the inlet of the key housing 25; in this position, under the action of the spring 33, the protective element 30 is in abutment thanks to a lug which it carries, not shown, and which cooperates with a stop provided in the housing 25, also not shown.

Ainsi, grâce à l'élément protecteur 30, le logement 25 est protégé contre les entrées d'eau et de poussière ; la durée de vie du verrou s'en trouve augmentée ; en outre, l'élément protecteur 30 et la plaque 35 peuvent être réalisés en un matériau résistant à une opération de perçage en vue d'une effraction.Thus, thanks to the protective element 30, the housing 25 is protected against the entry of water and dust; the life of the lock is thereby increased; in addition, the protective element 30 and the plate 35 can be made of a material resistant to a drilling operation with a view to break-in.

Lors de l'introduction de la clé dans le logement 25, la clé repousse l'élément protecteur 30 qui coulisse dans le logement 25, en comprimant le ressort 33. Lorsque la clé est retirée, l'élément protecteur 30 revient automatiquement, sous l'action du ressort 33, dans sa position de protection.When the key is inserted into the housing 25, the key pushes the protective element 30 which slides in the housing 25, compressing the spring 33. When the key is removed, the protective element 30 automatically returns, under the action of the spring 33, in its protective position.

La figure 2 représente, en coupe, un verrou 100 comprenant un stator 101 de section circulaire d'axe 102 ayant un alésage coaxial 103 dans lequel est monté à rotation un rotor 104 ; le rotor 104 est traversé par un alésage axial cylindrique 105 dont la section, non circulaire, est, selon un secteur 106, un arc de cercle centré sur l'axe 102 du rotor 104 et s'étendant sur moins de 360°, et, selon un autre secteur 107, de forme quelconque, en tout cas différente d'un arc de cercle selon le cercle du secteur 106. L'alésage 105 reçoit une clé 108 cylindrique dont l'enveloppe extérieure 109 a la forme complémentaire de l'alésage 105, au jeu de montage près, ladite enveloppe 109 étant creusée d'une gorge 110 s'étendant circonférentiellement à la périphérie de la clé 108 autour de l'axe 102 et limitée intérieurement par un fond 111 cylindrique de section circulaire dont l'axe 112 est distinct de l'axe 102 du rotor 104 et du stator 101.FIG. 2 represents, in section, a lock 100 comprising a stator 101 of circular section with axis 102 having a coaxial bore 103 in which a rotor 104 is rotatably mounted; the rotor 104 is crossed by a cylindrical axial bore 105, the non-circular section of which is, in a sector 106, an arc of a circle centered on the axis 102 of the rotor 104 and extending over less than 360 °, and, according to another sector 107, of any shape, in any case different from an arc of a circle along the circle of sector 106. The bore 105 receives a cylindrical key 108 whose outer casing 109 has the shape complementary to the bore 105, apart from the assembly clearance, said envelope 109 being hollowed out with a groove 110 extending circumferentially at the periphery of the key 108 around the axis 102 and internally limited by a cylindrical bottom 111 of section circular whose axis 112 is distinct from the axis 102 of the rotor 104 and the stator 101.

Le verrou 100 est muni d'éléments de condamnation 127 constitués, chacun, d'une paire de goupilles 114, 121.The lock 100 is provided with locking elements 127 each consisting of a pair of pins 114, 121.

La paroi du stator 101 est munie de perçages cylindriques radiaux 113 dans lesquels sont montées coulissantes des goupilles 114 de stator en forme de cuvette ayant un fond 115 ; un ressort 116 s'appuie, d'une part, sur le fond 115 et, d'autre part, sur un bouchon 117 fermant l'alésage 113 à la périphérie du stator 101, le ressort 116 sollicitant les goupilles 114 vers l'axe 102 du stator.The wall of the stator 101 is provided with radial cylindrical bores 113 in which are slidably mounted pins 114 of cup-shaped stator having a bottom 115; a spring 116 is supported, on the one hand, on the bottom 115 and, on the other hand, on a plug 117 closing the bore 113 at the periphery of the stator 101, the spring 116 urging the pins 114 towards the axis 102 of the stator.

La paroi du rotor 104 est également munie de perçages cylindriques radiaux 118 ayant une première partie 119 de section égale à la section des alésages 114 du stator 101 et débouchant à la périphérie du rotor 104 vers le stator 101, et une deuxième partie 120, de même axe que la première partie 119 mais de section plus petite, et débouchant dans l'alésage 105 du rotor 104. Dans les perçages 118 sont montées coulissantes des goupilles 121 de rotor de forme cylindrique comprenant une tête 122 coulissant dans la partie 119 du perçage 118 et une queue 123 coulissant dans la partie 120 du perçage 118 ; la face 124 de la tête 122 est cylindrique et sa section transversale est un arc de cercle dont le rayon est égal à celui de l'alésage 103 du stator ; la queue 123 se termine par une extrémité conique 125 qui est adaptée à coopérer avec le fond 111 de la gorge 110 de la clé 108 lorsque celle-ci est présente dans l'alésage 105 du rotor 104. Les longueurs des goupilles 121 de rotor, compte tenu de leur positionnement circonférentiel, sont telles que, leur partie conique étant en contact avec le fond 111 de la gorge 110, grâce aux ressorts 116, dans une position telle que celle qui est représentée sur la figure 2, toutes les faces 124 des goupilles 121 sont au droit de l'interstice radial existant par construction entre le stator 101 et le rotor 104 : dès lors, le rotor 104 peut tourner dans le stator 101 ; cette rotation est obtenue par simple rotation de la clé, la clé et le rotor 104 étant solidaires en rotation grâce aux secteurs complémentaires 107 portés par la clé et le rotor 104, secteurs qui ne sont pas de révolution autour de l'axe 102.The wall of the rotor 104 is also provided with radial cylindrical bores 118 having a first part 119 of section equal to the section of the bores 114 of the stator 101 and opening at the periphery of the rotor 104 towards the stator 101, and a second part 120, of same axis as the first part 119 but of smaller cross section, and opening into the bore 105 of the rotor 104. In the holes 118 are mounted sliding pins 121 of rotor of cylindrical shape comprising a head 122 sliding in the part 119 of the bore 118 and a tail 123 sliding in the part 120 of the bore 118; the face 124 of the head 122 is cylindrical and its cross section is an arc of a circle whose radius is equal to that of the bore 103 of the stator; the tail 123 ends with a conical end 125 which is adapted to cooperate with the bottom 111 of the groove 110 of the key 108 when the latter is present in the bore 105 of the rotor 104. The lengths of the pins 121 of the rotor, taking into account their circumferential positioning, are such that, their conical part being in contact with the bottom 111 of the groove 110, by virtue of the springs 116, in a position such as that which is represented in FIG. 2, all the faces 124 of the pins 121 are in line with the radial gap existing by construction between the stator 101 and the rotor 104: from then on, the rotor 104 can rotate in the stator 101; this rotation is obtained by simple rotation of the key, the key and the rotor 104 being integral in rotation thanks to the complementary sectors 107 carried by the key and the rotor 104, sectors which are not of revolution around the axis 102.

Lorsque la clé est retirée du verrou 100, les ressorts 116 sollicitent vers l'axe 102 les goupilles de stator 114 et de rotor 121 jusqu'à la venue en butée des têtes 122 contre la face transversale 126 séparant les parties 119 et 120 des perçages 118 du rotor 104. Dès lors, les goupilles de stator 114 s'étendent pour partie dans les perçages 113 du stator et pour partie dans les perçages 118 du rotor, ce qui bloque en rotation le rotor 104 par rapport au stator 101.When the key is removed from the lock 100, the springs 116 urge the stator 114 and rotor pins 121 towards the axis 102 until the heads 122 come into abutment against the transverse face 126 separating the parts 119 and 120 of the holes 118 of the rotor 104. Consequently, the stator pins 114 extend partly in the holes 113 of the stator and partly in the holes 118 of the rotor, which stops the rotor 104 from rotating relative to the stator 101.

La figure 3 est relative à une variante de verrou selon l'invention, permettant l'utilisation d'une clé symétrique. Sur cette figure, le rotor 204 est traversé par un alésage axial cylindrique 205 dont la section est formée de deux secteurs circulaires 206A, 206B appartenant à un même cercle centré sur l'axe 202 du rotor 204, qui est aussi l'axe du stator 201 dans lequel le rotor 204 est monté, et de deux plats 207A, 207B, les deux secteurs circulaires 206A, 206B étant symétriques par rapport à un plan de symétrie passant par l'axe 202 et dont on voit la trace 230 dans le plan de la figure 3, les deux plats 207A, 207B étant perpendiculaires à la trace 230 et se faisant face.Figure 3 relates to a variant lock according to the invention, allowing the use of a symmetrical key. In this figure, the rotor 204 is crossed by a cylindrical axial bore 205 whose section is formed of two circular sectors 206A, 206B belonging to the same circle centered on the axis 202 of the rotor 204, which is also the axis of the stator 201 in which the rotor 204 is mounted, and two flats 207A, 207B, the two circular sectors 206A, 206B being symmetrical with respect to a plane of symmetry passing through the axis 202 and of which we see the trace 230 in the plane of Figure 3, the two dishes 207A, 207B being perpendicular to the trace 230 and facing each other.

L'alésage 205 reçoit une clé 208 cylindrique dont l'enveloppe extérieure 209 a la forme complémentaire de l'alésage 205, au jeu de montage près, ladite enveloppe 209 étant creusée d'une gorge 210 s'étendant circonférentiellement autour de l'axe 202 et limitée intérieurement par un fond 211 cylindrique dont la section est une ellipse ayant son centre sur l'axe 202 et un grand axe 231 qui est aussi un axe de symétrie pour l'ellipse 211.The bore 205 receives a cylindrical key 208 whose outer casing 209 has the shape complementary to the bore 205, apart from the mounting clearance, said casing 209 being hollowed out by a groove 210 extending circumferentially around the axis 202 and internally limited by a cylindrical bottom 211 whose section is an ellipse having its center on the axis 202 and a major axis 231 which is also an axis of symmetry for the ellipse 211.

Comme dans la variante précédente, le stator 201 et le rotor 204 sont munis de perçages radiaux, respectivement 213 et 218, dans lesquels sont montées à coulissement des goupilles de stator 214 et de rotor 221, sollicitées vers l'axe 202 par des ressorts 216 qui prennent appui sur des bouchons 217, et constituant des éléments de condamnation 227.As in the previous variant, the stator 201 and the rotor 204 are provided with radial holes, respectively 213 and 218, in which the stator pins 214 and rotor pins 221 are slidably mounted, biased towards the axis 202 by springs 216 which are supported on plugs 217, and constituting locking elements 227.

La longueur des goupilles 221 de rotor, l'inclinaison du grand axe 231 de l'ellipse 211, les caractéristiques géométriques de l'ellipse 211, notamment la longueur de son grand axe et celle de son petit axe, sont choisis de façon telle que dans une position, qui est celle de la figure 3, les goupilles de rotor 221 sont toutes au droit de l'interstice rotor-stator, pour permettre, lorsque la clé est présente, au rotor 204 de pouvoir tourner dans le stator 201.The length of the rotor pins 221, the inclination of the major axis 231 of the ellipse 211, the geometrical characteristics of the ellipse 211, in particular the length of its major axis and that of its minor axis, are chosen such that in a position, which is that of FIG. 3, the rotor pins 221 are all in line with the rotor-stator gap, to allow, when the key is present, the rotor 204 to be able to turn in the stator 201.

Le fonctionnement de cette variante est identique à celui de la variante précédente ; ici, la clé est symétrique, ce qui rend son utilisation plus aisée, et sa copie plus difficile.The operation of this variant is identical to that of the previous variant; here, the key is symmetrical, which makes it easier to use and more difficult to copy.

Dans les exemples ci-dessus décrits et représentés, les goupilles sont dans un seul et même plan, et au nombre de trois ; bien entendu, plusieurs plans peuvent être prévus, chacun contenant deux ou plusieurs éléments de condamnation, ceci augmentant le nombre de combinaisons possibles, donc de variantes de clé.In the examples described and shown above, the pins are in one and the same plane, and three in number; of course, several plans can be provided, each containing two or more locking elements, this increasing the number of possible combinations, therefore of key variants.

Bien entendu, des longueurs différentes de goupilles de rotor participent, comme connu en soi, à cette augmentation du nombre de combinaisons. Dans un exemple de réalisation selon la figure 2, on a obtenu, avec 5 longueurs différentes de goupilles de rotor, deux gorges dans la clé et 3 éléments de condamnation par gorge, plus de 15000 combinaisons. Selon ces mêmes éléments, on a obtenu tout autant de combinaisons avec une réalisation à fond de gorge elliptique, selon la figure 3, cette dernière réalisation, symétrique, conduisant à disposer d'une clé également symétrique, ce qui rend plus confortable l'utilisation d'une telle clé.Of course, different lengths of rotor pins participate, as known per se, in this increase in the number of combinations. In an exemplary embodiment according to FIG. 2, there were obtained, with 5 different lengths of rotor pins, two grooves in the key and 3 locking elements per groove, more than 15,000 combinations. According to these same elements, just as many combinations were obtained with an embodiment at the bottom of an elliptical groove, according to FIG. 3, this latter embodiment, symmetrical, leading to having a key also symmetrical, which makes use more comfortable. of such a key.

On notera l'encombrement axial de tels verrous extérieurement réduit, donc également celui des clés, ce qui facilite l'implantation d'un élément protecteur du type décrit ci-dessus, en référence à la figure 1.Note the axial size of such externally reduced locks, therefore also that of the keys, which facilitates the installation of a protective element of the type described above, with reference to FIG. 1.
