Definitions
- the present invention essentially relates to a safety device allowing the control of any lock mechanism and capable of achieving a blocking of the barrel in the event of an attempt to force it by pushing it in using a tool or of a false key.
- This invention also relates to a lock mechanism equipped with such a safety device.
- Safety devices are already known which allow the control of a lock mechanism by means of a driving element which is axially coupled to a barrel rotatably mounted in a body and actuable by a key.
- the main object of the present invention is to remedy the above drawback by proposing a safety device which blocks or locks the barrel in the body in the event of an forcing attempt.
- the subject of the invention is a safety device for controlling a lock mechanism by means of a driving element which is axially associated with a barrel rotatably mounted in a body and actuable by a key, characterized in that the barrel or the driving element comprises deformable lugs capable of blocking the barrel-driving element assembly in rotation in the body under the effect of a forcing action by depressing the sliding barrel under the action of 'a tool or a false key.
- the aforementioned tabs are integral with the barrel and are received in notches provided on the periphery of the driving element.
- the aforementioned tabs are integral with the driving element and are capable of cooperating with at least one safety member, such as for example a chuck.
- this spigot In the event of forcing by pressing in the barrel, this spigot, causing the deformation of the tabs, locks the barrel-entraining element assembly in the body, while in the event of actuation of the barrel by the appropriate key, said spigot cooperates with the tabs to allow the rotation of the barrel-driver element assembly in the body.
- the aforementioned chin, mounted sliding in the barrel is held by a spring in a recess or the like formed on the internal periphery of the body so as to thus prevent any rotation of the barrel in the body, while in the active or actuating position of the barrel by the key which controls the linings or the like, said chin, released by the alignment of said linings, moves towards them by cooperation with the 'free and tapered end of the legs to finally allow the rotation of the barrel-driver element assembly in the body.
- a spring arranged axially between the driving element and the barrel, and another spring arranged axially between said barrel and the linings.
- a safety device essentially comprises a barrel 1 rotatably mounted in a body 2 and actuable by a key (not shown).
- the barrel 1 is axially coupled to a driving element 3 capable of actuating any lock mechanism (not shown), under the effect of the rotation of the barrel 1 caused by the key.
- the key When the key is introduced into the body 2 through the inlet 4, it causes the linings or the like (not shown) of the barrel 1 to be aligned, so as to allow the latter and the driving element 3 to rotate in the body 2, at the same time as the thrust by the key of a small piston 5 urged by a spring 6 and comprising at its end an end piece 7 meshing with the lock mechanism.
- a chin here having the shape of a small cylindrical rod and normally cooperating with a groove formed in the internal periphery of the body 2 to prevent the barrel 1 from rotating in this body in the absence of the introduction of the key in the barrel 1.
- the barrel 1 is provided with deformable lugs P which extend substantially parallel to the axis of the barrel.
- These legs P are in reality part of a ring 8 fixed on the barrel 1, at one end of it, but it could perfectly well, without departing from the scope of the invention, ensure that the legs P are integral with the barrel 1.
- the legs P are tapered from where they originate on the ring 8 to their free end, and they are received in notches 9 provided on the outer periphery of the element coach 3 and which are clearly visible in FIG. 4. These notches 9 cooperating with the legs P each have a shape of a ramp, as can be seen clearly in FIGS. 1 and 3.
- the ring 8 carrying the tabs P also comprises two pins 10 slidingly entering the driving element 3 and ensuring the coupling in rotation of this driving element with the barrel 1. But these pins 10 are in no way obligatory since the coupling in rotation in question could quite simply be ensured by the cooperation of the legs P and the notches in the form of a ramp 9 of the driving element 3.
- the barrel 1 will be keyed in a way, by the lugs P on the body 2 and the rotation of the barrel 1 - driving element 3 assembly in the body 2 will be definitively prohibited. In other words, any axial forcing action on the barrel 1 will necessarily cause a positive and final locking in rotation of the aforementioned assembly in the body 2 of the safety device.
- the legs P are integral with the driving element 3 axially coupled in rotation to the barrel 1.
- the legs P can cooperate with at least one safety member, such as for example a spigot 12 mounted to slide in the barrel 1 orthogonally to its axis, and constantly stressed by a spring 13 (FIG. 11) in a recess or recess 14 formed in the periphery of the body 2.
- the jib 12 in the event of forcing by pressing in the barrel 1, locks the barrel 1 - driving element 3 assembly in the body 2, while in the case of normal actuation of the barrel 1 by the appropriate key 15 (FIG. 7), said chin cooperates with the legs P to allow the rotation of the aforementioned assembly in the body 2.
- the barrel 1 comprises, as known per se, a plurality of relatively mobile linings 16 and each comprising a notch 17.
- the introduction of the key 15 into the barrel 1 will allow alignment notches 17 of all the linings 16, so that the chin 12 can move towards these linings by entering the notches 17, and this thanks to the tapered ramp-shaped end 18 of the legs P on which the chin can mount 12.
- the chin 12 having come out of its notch 14, the barrel assembly 1 - driving element 3 can rotate in the body 2.
- a spring arranged axially between the driving element 3 and the barrel 1.
- Another spring 20 is axially arranged in the barrel 1 between the bottom of this barrel and the linings 16 to return them to their initial position after removal of the key 15.
- the barrel 1 When the key 15, as can be seen in FIG. 7, is introduced, which causes the notches 17 of the linings 16 to be aligned, the barrel 1 will be pushed axially by virtue of the erasure of the flange 12 by the ramp 18 of the 'driving element 3, the displacement of said chin perpendicular to the axis of the barrel 1 being authorized by the prior alignment of the notches 17 into which penetrates the end of the chin opposite to that cooperating with the legs P.
- the chin 12 In the event of an attempt to force the barrel 1 by pressing in using a false key or a tool F, the chin 12 cannot be erased when entering the linings 16, and will force on the legs P of the driving element 3.
- the end of the legs P comprising the ramp 18 deforms elastically and radially outward to come to be housed in the groove 11 on the internal periphery of the body 2.
- any rotation of the barrel 1 and of the driving element 3 in the body 2 is positively prevented. This means that there is blockage of the barrel assembly 1 - driving element 3 in the body 2, and that consequently the lock mechanism cannot be actuated.
- a safety device has therefore been produced according to the invention, the active parts of which are blocked or locked together during an attack on the barrel with a false key or any forcing tool.

Description
La présente invention a essentiellement pour objet un dispositif de sûreté permettant la commande d'un mécanisme de serrure quelconque et apte à réaliser un blocage du barillet en cas de tentative de forçage par enfoncement de celui-ci à l'aide d'un outil ou d'une fausse clé.The present invention essentially relates to a safety device allowing the control of any lock mechanism and capable of achieving a blocking of the barrel in the event of an attempt to force it by pushing it in using a tool or of a false key.
Cette invention vise également un mécanisme de serrure équipé d'un tel dispositif de sûreté.This invention also relates to a lock mechanism equipped with such a safety device.
On connaît déjà des dispositifs de sûreté permettant la commande d'un mécanisme de serrure par l'intermédiaire d'un élément entraîneur qui est couplé axialement à un barillet monté rotatif dans un corps et actionnable par une clé.Safety devices are already known which allow the control of a lock mechanism by means of a driving element which is axially coupled to a barrel rotatably mounted in a body and actuable by a key.
Toutefois, avec ce genre de dispositif de sûreté, un cambrioleur expérimenté et bien équipé pouvait réussir à faire tourner le barillet dans le corps, c'est-à-dire à actionner le mécanisme de serrure, par l'introduction à force d'un outil ou d'une fausse clé dans le corps, de façon à provoquer l'enfoncement du barillet ou cylindre, et par la suite la rotation dudit barillet dans le corps.However, with this kind of security device, an experienced and well-equipped burglar could succeed in rotating the barrel in the body, that is to say, actuating the lock mechanism, by forcefully inserting a tool or a false key in the body, so as to cause the depression of the barrel or cylinder, and thereafter the rotation of said barrel in the body.
La présente invention a essentiellement pour but de remédier à l'inconvénient ci-dessus en proposant un dispositif de sûreté réalisant un blocage ou clavetage du barillet dans le corps en cas de tentative de forçage.The main object of the present invention is to remedy the above drawback by proposing a safety device which blocks or locks the barrel in the body in the event of an forcing attempt.
A cet effet, l'invention a pour objet un dispositif de sûreté pour la commande d'un mécanisme de serrure par l'intermédiaire d'un élément entraîneur qui est axialement associé à un barillet monté rotatif dans un corps et actionnable par une clé, caractérisé en ce que le barillet ou l'élément entraîneur comporte des pattes déformables susceptibles de bloquer l'ensemble barillet-élément entraîneur en rotation dans le corps sous l'effet d'une action de forçage par enfoncement du barillet coulissant sous l'action d'un outil ou d'une fausse clé.To this end, the subject of the invention is a safety device for controlling a lock mechanism by means of a driving element which is axially associated with a barrel rotatably mounted in a body and actuable by a key, characterized in that the barrel or the driving element comprises deformable lugs capable of blocking the barrel-driving element assembly in rotation in the body under the effect of a forcing action by depressing the sliding barrel under the action of 'a tool or a false key.
Suivant un mode de réalisation, les pattes précitées sont solidaires du barillet et sont reçues dans des encoches prévues sur la périphérie de l'élément entraîneur.According to one embodiment, the aforementioned tabs are integral with the barrel and are received in notches provided on the periphery of the driving element.
Ces pattes sont avantageusement effilées vers leur extrémité libre, tandis que les encoches précitées coopérant avec les pattes présentent chacune une forme de rampe.These legs are advantageously tapered towards their free end, while the aforementioned notches cooperating with the legs each have a ramp shape.
Suivant un autre mode de réalisation, les pattes précitées sont solidaires de l'élément entraîneur et sont susceptibles de coopérer avec au moins un organe de sûreté, tel que par exemple un mentonnet.According to another embodiment, the aforementioned tabs are integral with the driving element and are capable of cooperating with at least one safety member, such as for example a chuck.
En cas de forçage par enfoncement du barillet, ce mentonnet, provoquant la déformation des pattes, réalise le blocage de l'ensemble barillet-élément entraîneur dans le corps, tandis qu'en cas d'actionnement du barillet par la clé adéquate, ledit mentonnet coopère avec les pattes pour autoriser la rotation de l'ensemble barillet-élément entraîneur dans le corps.In the event of forcing by pressing in the barrel, this spigot, causing the deformation of the tabs, locks the barrel-entraining element assembly in the body, while in the event of actuation of the barrel by the appropriate key, said spigot cooperates with the tabs to allow the rotation of the barrel-driver element assembly in the body.
On précisera encore ici qu'en position inactive, le mentonnet précité, monté coulissant dans le barillet est maintenu par un ressort dans un embrèvement ou analogue ménagé sur la périphérie interne du corps de façon à empêcher ainsi toute rotation du barillet dans le corps, tandis qu'en position active ou d'actionnenment du barillet par la clé qui commande des garnitures ou analogues, ledit mentonnet, libéré par l'alignement desdites garnitures, se déplace vers celles-ci par coopération avec l'extrémité libre et effilée des pattes pour finalement autoriser la rotation de l'ensemble barillet-élément entraîneur dans le corps.It will also be specified here that in the inactive position, the aforementioned chin, mounted sliding in the barrel is held by a spring in a recess or the like formed on the internal periphery of the body so as to thus prevent any rotation of the barrel in the body, while in the active or actuating position of the barrel by the key which controls the linings or the like, said chin, released by the alignment of said linings, moves towards them by cooperation with the 'free and tapered end of the legs to finally allow the rotation of the barrel-driver element assembly in the body.
Selon encore une autre exécution de la réalisation ci-dessus, il est prévu un ressort agencé axialement entre l'élément entraîneur et le barillet, et un autre ressort agencé axialement entre ledit barillet et les garnitures.According to yet another embodiment of the above embodiment, there is provided a spring arranged axially between the driving element and the barrel, and another spring arranged axially between said barrel and the linings.

Suivant l'exemple de réalisation illustré par les figures 1 à 4, un dispositif de sûreté selon cette invention comprend essentiellement un barillet 1 monté rotatif dans un corps 2 et actionnable par une clé (non représentée). Le barillet 1 est axialement couplé à un élément entraîneur 3 susceptible d'actionner un mécanisme de serrure quelconque (non représenté), sous l'effet de la rotation du barillet 1 provoquée par la clé.According to the embodiment illustrated in Figures 1 to 4, a safety device according to this invention essentially comprises a
Lorsque la clé est introduite dans le corps 2 par l'entrée 4, elle provoque l'alignement des garnitures ou analogues (non représentées) du barillet 1, de façon à permettre la rotation de celui-ci et de l'élément entraîneur 3 dans le corps 2, en même temps que la poussée par la clé d'un petit piston 5 sollicité par un ressort 6 et comportant à son extrémité un embout 7 d'engrènement avec le mécanisme de serrure.When the key is introduced into the
On a montré en la un mentonnet présentant ici la forme d'une petite tige cylindrique et coopérant normalement avec une rainure ménagée dans la périphérie interne du corps 2 pour empêcher le barillet 1 de tourner dans ce corps en l'absence de l'introduction de la clé dans le barillet 1.There has been shown in the a chin here having the shape of a small cylindrical rod and normally cooperating with a groove formed in the internal periphery of the
Toutes les dispositions ci-dessus sont connues en soi et ne méritent pas d'explications complémentaires.All the above provisions are known per se and do not deserve further explanation.
Conformément à l'invention, et comme on le voit bien sur les figures 1 à 4, le barillet 1 est muni de pattes déformables P qui s'étendent sensiblement parallèlement à l'axe du barillet. Ces pattes P font en réalité partie d'une bague 8 fixée sur le barillet 1, à une extrémité de celui-ci, mais on pourrait parfaitement, sans sortir du cadre de l'invention, faire en sorte que les pattes P soient intégrales au barillet 1.According to the invention, and as can be seen in Figures 1 to 4, the
Comme on le voit bien sur les figures, les pattes P sont effilées depuis l'endroit où elles prennent naissance sur la bague 8 jusqu'à leur extrémité libre, et elles sont reçues dans des encoches 9 prévues sur la périphérie externe de l'élément entraîneur 3 et qui sont bien visibles sur la figure 4. Ces encoches 9 coopérant avec les pattes P présentent chacune une forme de rampe, comme on le voit bien sur les figures 1 et 3.As can be seen in the figures, the legs P are tapered from where they originate on the ring 8 to their free end, and they are received in
Comme on le voit bien sur la figure 2, la bague 8 portant les pattes P comporte en outre deux tétons 10 pénétrant à coulissement dans l'élément entraîneur 3 et assurant le couplage en rotation de cet élément entraîneur avec le barillet 1. Mais ces tétons 10 ne sont nullement obligatoires puisque le couplage en rotation en question pourrait tout simplement être assuré par la coopération des pattes P et des encoches en forme de rampe 9 de l'élément entraîneur 3.As can be clearly seen in FIG. 2, the ring 8 carrying the tabs P also comprises two
Pour une meilleure compréhension de l'invention, on expliquera ci-après, en se reportant plus particulièrement à la figure 3, comment s'effectue le blocage de l'ensemble barillet 1 - élément entraîneur 3 dans le corps 2, sous l'effet d'une tentative de forçage. En cas de fonctionnement normal, l'introduction de la bonne clé dans le barillet 1 provoquera l'entraînement de l'ensemble barillet 1 - élément entraîneur 3 et par conséquent l'actionnement du mécanisme de serrure, comme cela a été décrit précédemment en référence à la figure 1.For a better understanding of the invention, we will explain below, with particular reference to Figure 3, how the blocking of the barrel assembly 1 - driving
Si, à l'aide d'une fausse clé, ou d'un outil de forçage, on enfonce le barillet 1 dans le corps 2, comme montré sur la figure 3, les pattes P se déformeront élastiquement et radialement vers l'extérieur en prenant appui sur les encoches en forme de rampes 9, pour finalement venir se loger dans des rainures ou analogues 11 (voir figure 4) prévues sur la périphérie interne du corps 2.If, using a dummy key, or a forcing tool, the
Dès lors, le barillet 1 sera en quelque sorte claveté, par les pattes P sur le corps 2 et la rotation de l'ensemble barillet 1 - élément entraîneur 3 dans le corps 2 sera définitivement interdite. Autrement dit, toute action de forçage axiale sur le barillet 1 provoquera nécessairement un blocage en rotation positif et définitif de l'ensemble précité dans le corps 2 du dispositif de sûreté.Consequently, the
On décrira maintenant le mode de réalisation illustré par les figures 5 à 11 où on a utilisé les mêmes repères que sur les figures 1 à 4 pour désigner les éléments communs.We will now describe the embodiment illustrated in Figures 5 to 11 where we used the same references as in Figures 1 to 4 to designate the common elements.
Ici, les pattes P sont solidaires de l'élément entraîneur 3 axialement couplé en rotation au barillet 1. Les pattes P peuvent coopérer avec au moins un organe de sûreté, tel que par exemple un mentonnet 12 monté coulissant dans le barillet 1 orthogonalement à son axe, et constamment sollicité par un ressort 13 (figure 11) dans un logement ou embrèvement 14 ménagé dans la périphérie du corps 2.Here, the legs P are integral with the
Comme on le décrira en détail plus loin à propos du fonctionnement, le mentonnet 12, en cas de forçage par enfoncement du barillet 1 réalise le blocage de l'ensemble barillet 1 - élément entraîneur 3 dans le corps 2, tandis qu'en cas d'actionnement normal du barillet 1 par la clé adéquate 15 (figure 7), ledit mentonnet coopère avec les pattes P pour autoriser la rotation de l'ensemble précité dans le corps 2.As will be described in detail below with regard to the operation, the
Comme il apparaît clairement sur les figures 5 à 10, le barillet 1 comporte, comme connu en soi, une pluralité de garnitures 16 relativement mobiles et comportant chacune une encoche 17. L'introduction de la clé 15 dans le barillet 1 permettra l'alignement des encoches 17 de toutes les garnitures 16, de sorte que le mentonnet 12 pourra se déplacer vers ces garnitures en pénétrant dans les encoches 17, et cela grâce à l'extrémité effilée en forme de rampe 18 des pattes P sur laquelle pourra monter le mentonnet 12. Ainsi, le mentonnet 12 étant sorti de son encoche 14, l'ensemble barillet 1 - élément entraîneur 3 pourra tourner dans le corps 2.As it clearly appears in FIGS. 5 to 10, the
On a montré en 19 un ressort agencé axialement entre l'élément entraîneur 3 et le barillet 1. Un autre ressort 20 est axialement agencé dans le barillet 1 entre le fond de ce barillet et les garnitures 16 pour les ramener à leur position initiale après retrait de la clé 15.There is shown in 19 a spring arranged axially between the driving
On décrira ci-après en détail le fonctionnement du dispositif de sûreté qui vient d'être décrit en se reportant plus particulièrement et successivement aux figures 5, 7 et 9.The operation of the safety device which has just been described will be described below in detail, referring more particularly and successively to FIGS. 5, 7 and 9.
En fonctionnement normal et en l'absence de clé, le barillet 1 et immobilisé en rotation dans le corps 2 par le ou les mentonnets 12 sollicités par le ressort 13 dans l'encoche 14, comme on le voit bien sur la figure 5.In normal operation and in the absence of a key, the
Lorsque la clé 15, comme on le voit sur la figure 7, est introduite, ce qui provoque l'alignement des encoches 17 des garnitures 16, le barillet 1 sera poussé axialement grâce à l'effacement du mentonnet 12 par la rampe 18 de l'élément entraîneur 3, le déplacement dudit mentonnet perpendiculairement à l'axe du barillet 1 étant autorisé par l'alignement préalable des encoches 17 dans lesquelles pénètre l'extrémité du mentonnet opposée à celle coopérant avec les pattes P.When the
Dès lors la rotation de l'ensemble barillet 1 - élément entraîneur 3 est permise et assurée par la rotation de la clé. On a montré schématiquement en 21 sur les figures 5, 7 et 9 le couplage en rotation du barillet 1 et de l'élément entraîneur 3.Therefore the rotation of the barrel assembly 1 - driving
Bien évidemment lorsque la clé 15 sera retirée, le barillet 1 reculera et reprendra sa place initiale et visible sur la figure 5, comme cela sera aussi le cas pour les garnitures 16 qui retourneront à l'état désaligné, grâce aux ressorts 19 et 20 respectivement.Obviously when the key 15 is withdrawn, the
En cas de tentative de forçage par enfoncement du barillet 1 à l'aide d'une fausse clé ou d'un outil F, le mentonnet 12 ne peut pas s'effacer en pénétrant dans les garnitures 16, et viendra forcer sur les pattes P de l'élément entraîneur 3.In the event of an attempt to force the
Plus précisément, et comme on le voit bien sur la figure 9, l'extrémité des pattes P comportant la rampe 18 se déforme élastiquement et radialement vers l'extérieur pour venir se loger dans la rainure 11 sur la périphérie interne du corps 2. Ainsi, toute rotation du barillet 1 et de l'élément entraîneur 3 dans le corps 2 est positivement empêchée. C'est dire qu'il y a blocage de l'ensemble barillet 1 - élément entraîneur 3 dans le corps 2, et que par conséquent le mécanisme de serrure ne pourra pas être actionné.More precisely, and as can be seen in FIG. 9, the end of the legs P comprising the
On a donc réalisé suivant l'invention un dispositif de sûreté dont les pièces actives sont bloquées ou verrouillées entre elles lors d'une attaque du barillet avec une fausse clé ou un outil de forçage quelconque.A safety device has therefore been produced according to the invention, the active parts of which are blocked or locked together during an attack on the barrel with a false key or any forcing tool.
Bien entendu, l'invention n'est nullement limitée aux modes de réalisation décrits et illustrés qui n'ont été donnés qu'à titre d'exemple.Of course, the invention is in no way limited to the embodiments described and illustrated which have been given only by way of example.
Au contraire, l'invention comprend tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons tels qu'ils ont été revendiqués.On the contrary, the invention includes all the technical equivalents of the means described as well as their combinations as claimed.
