Abstract

A universal anti-drilling plate (8) for a cylinder lock with a rotor/false stator assembly in which the rotor (4) has a collar (7) covering the end face of the false stator (3) and a slot (9) for a key (5). The plate is made by fritting or moulding from a material that is resistant to drilling. e.g. a hard steel alloy with an Rm resistance of over 500 MPa, and is connected to the rotor by one or more projecting pegs (12) engaging with the rotor slot but without hindering the insertion of the key.

Description

L'invention concerne le domaine des serrures et, plus spécialement, est relative à un cylindre de serrure avec pastille anti-perçage.The invention relates to the field of locks and, more especially, relates to a lock cylinder with anti-drilling pad.

Pour protéger contre une effraction par perçage, le rotor ou l'ensemble rotor-faux-stator d'un cylindre de serrure, il est connu, en particulier par FR-A-1027674, d'interposer, entre la face au bout de cet ensemble rotor stator et un retour de l'enveloppe extérieur du cylindre, une pastille en matériau résistant au perçage, par exemple en acier traité.To protect against break-in by drilling, the rotor or the rotor-dummy stator assembly of a lock cylinder, it is known, in particular by FR-A-1027674, to interpose, between the face at the end of this rotor assembly stator and a return of the outer casing of the cylinder, a pellet of material resistant to drilling, for example in treated steel.

Pour permettre le passage de la clef, la pastille comporte une fente qui doit être alignée avec celle du rotor. Selon les formes de réalisation définies par les divers fabricants, la liaison en rotation pastille-rotor s'effectue de diverses manières :

  • par la clef, cas dans lequel la pastille est libre en rotation en l'absence de clef,
  • par des pions longitudinaux saillants de la face arrière de la pastille et/ou de la face avant du rotor et pénétrant dans des perçages de la face en vis-à-vis,
  • ou par encastrement de profils complémentaires, ces deux techniques étant décrites dans FR-A-1 027 674.
To allow the passage of the key, the patch has a slot which must be aligned with that of the rotor. According to the embodiments defined by the various manufacturers, the connection in rotation between the disc and the rotor is carried out in various ways:
  • by the key, case in which the pellet is free to rotate in the absence of a key,
  • by protruding longitudinal pins of the rear face of the patch and / or of the front face of the rotor and penetrating into bores of the face opposite,
  • or by embedding complementary profiles, these two techniques being described in FR-A-1 027 674.

Les liaisons en rotation assurées par les deux derniers moyens ci-dessus présentent l'inconvénient d'apparier rotor et pastille et d'empêcher, par exemple lors d'une réparation après fracturation, la réparation immédiate d'un cylindre ou d'une pastille par un élément de rechange provenant d'un autre fabricant.The rotational links provided by the last two means above have the disadvantage of matching rotor and pellet and preventing, by example during a repair after fracturing, the immediate repair of a cylinder or pellet by a replacement from another maker.

L'objet de l'invention est de remédier à cet inconvénient en fournissant une pastille s'adaptant à tous les types d'ensemble rotor-faux-stator indus dans une enveloppe.The object of the invention is to remedy this drawback by providing a pad suitable for all types of rotor-false stator assembly undue in an envelope.

Le document US 1 882 626 décrit un contacteur quart de tour dans lequel l'extrémité du rotor d'un cylindre de serrure disposé dans une enveloppe est capotée par un capuchon de protection équipé d'une fente pour le passage de la clé. Pour assurer la coïncidence entre la fente du capuchon et celle du rotor, le capuchon est solidaire d'un ergot qui, formé par un crevé de sa paroi avant, pénètre dans la fente du rotor. Le capuchon est réalisé dans un métal durci pour former un boítier de protection s'opposant à la destruction du verrou. Toutefois, la qualité des outils tranchants s'étant bien améliorée depuis le dépôt de ce brevet américain, un tel capuchon ne pourrait pas résister aux outils actuels, tels que pinces ou forets, utilisés pour le fracturer par perçage ou écartement des bords de la fente. Document US 1,882,626 describes a quarter turn contactor in which the end of the rotor of a lock cylinder arranged in an envelope is covered by a protective cap fitted with a slot for passage of the key. To ensure the coincidence between the slot of the cap and that of the rotor, the cap is integral with a lug which, formed by a puncture in its wall front, enters the rotor slot. The cap is made of a metal hardened to form a protective case opposing the destruction of the lock. However, the quality of cutting tools having improved considerably since the filing of this American patent, such a cap could not withstand current tools, such as pliers or drills, used to break it by drilling or spacing of the edges of the slot.

L'invention est définie par les caractéristiques de la revendication 1.The invention is defined by the features of claim 1.

Selon l'invention, la pastille est réalisée par frittage ou moulage MIM dans un matériau résistant au perçage, tandis que ses moyens de liaison en rotation avec le rotor sont constitués par un doigt qui, saillant de la pastille, sensiblement radialement et en direction du rotor, est disposé dans l'alignement et le prolongement de la fente de la pastille et longitudinalement derrière la paroi de cette pastille qui est traversée par la fente, et lorsque les éléments du cylindre sont assemblés le doigt s'insère dans la partie de fente du rotor débouchant radialement à l'extérieur de la collerette de ce rotor, sans gêner l'engagement de la clé, ledit doigt ayant une résistance lui permettant de casser en cas de tentative d'effraction de la serrure.According to the invention, the pellet is produced by sintering or MIM molding in a material resistant to drilling, while its connecting means rotation with the rotor are constituted by a finger which, projecting from the pellet, substantially radially and in the direction of the rotor, is arranged in the alignment and the extension of the slot of the patch and longitudinally behind the wall of this patch which is crossed by the slot, and when the elements of the cylinder are assembled the finger is inserted into the slot portion of the through rotor radially outside the flange of this rotor, without hampering engagement of the key, said finger having a resistance allowing it to break in the event of attempt to break the lock.

Cette pastille anti-perçage s'applique à tous les cylindres dont le rotor est équipé d'une collerette dont la fente débouche radialement du rotor aussi bien en première monte et deuxième monte que lors d'une réparation. Le doigt, qui assure la liaison en rotation de la pastille avec le rotor et évite donc que la pastille prenne une position angulaire entraínant le désalignement de sa fente d'avec celle du rotor, apporte, par sa base, un supplément de matière dans la zone de liaison entre les bords de la fente ménagée dans la pastille et contribue donc à augmenter la résistance à l'écartement de ces bords.This anti-drilling tablet applies to all cylinders whose rotor is fitted with a flange, the slot of which opens radially from the rotor as well as original equipment and after installation as during a repair. The finger, which ensures the rotational connection of the pellet with the rotor and therefore avoids that the pellet takes an angular position causing the misalignment of its slit with that of the rotor, brings, by its base, an additional material in the connection zone between the edges of the slot made in the patch and therefore contributes to increasing the resistance to the spreading of these edges.

  • FIG. 2 is a view in partial longitudinal section of a cylinder fitted with the pellet of FIG. 1,

    • Dans la forme d'exécution montrée à la figure 2, le cylindre est composé d'une enveloppe extérieure 2 dans laquelle sont disposés un faux stator 3, calé en rotation par rapport à l'enveloppe 2, et un rotor 4, monté libre en rotation dans le faux stator et immobilisé dans celui-ci par des pistons à ressort, non représentés, actionnables par une clef 5. In the embodiment shown in Figure 2, the cylinder is composed of an outer envelope 2 in which are arranged a false stator 3, set in rotation relative to the casing 2, and a rotor 4, mounted free rotating in the false stator and immobilized therein by pistons spring, not shown, actuated by a key 5.

    Le rotor 4 comporte une sabrure ou fente longitudinale 6 qui s'étend sur toute sa longueur. Il est muni, à son extrémité antérieure, d'une collerette 7 par laquelle il vient en appui contre la face en bout antérieure du faux stator 3. La fente 6 du rotor s'étend, dans la collerette, par une partie 6a débouchant radialement à l'extérieur.The rotor 4 has a longitudinal groove or slot 6 which extends over its entire length. It is provided, at its anterior end, with a collar 7 by which it bears against the front end face of the false stator 3. The slot 6 of the rotor extends, in the collar, by a part 6a opening out radially outside.

    Le cylindre est équipé d'une pastille anti-perçage 8 interposée entre l'ensemble rotor faux stator et un collet 2a de l'enveloppe 2. Cette pastille est montée libre en rotation dans l'enveloppe 2 et est traversée longitudinalement par une fente 9.The cylinder is fitted with an anti-drilling pad 8 interposed between the false stator rotor assembly and a collar 2a of the casing 2. This patch is free rotationally mounted in the casing 2 and is traversed longitudinally through a slot 9.

    Dans cette forme d'exécution, la pastille est solidaire d'un anneau 10 coiffant la collerette 7 du rotor 4 et protégeant le faux stator 3.In this embodiment, the patch is integral with a ring 10 covering the flange 7 of the rotor 4 and protecting the false stator 3.

    Comme montré plus en détail à la figure 1, l'anneau 10 est solidaire d'un doigt 12 qui forme une saillie sensiblement radiale tournée vers l'intérieur de cet anneau et en direction de la collerette 7. Cette saillie est disposée, angulairement, dans l'alignement de la fente 9 de la pastille 8 et longitudinalement, en arrière de la paroi 11 dans laquelle cette fente est réalisée.As shown in more detail in Figure 1, the ring 10 is integral a finger 12 which forms a substantially radial projection facing inwards of this ring and in the direction of the collar 7. This projection is arranged, angularly, in alignment with the slot 9 of the patch 8 and longitudinally, behind the wall 11 in which this slot is performed.

    Comme montré sur les figures 2 et 3, lorsque les éléments du cylindre sont assemblés, le doigt 12 s'insère dans la partie de fente 6a qui débouche de la collerette 7 dans le prolongement radial de la fente 6 du rotor 4 et assure ainsi la liaison en rotation de la pastille 8 avec ce rotor 4. Il est bien évident que le doigt 12 a une largeur inférieure à la largeur de la fente 6 pour pouvoir s'insérer dans celle-ci avec un jeu suffisant. Le doigt 12 a une hauteur déterminée pour s'étendre dans la collerette 7, sans pour autant venir au niveau du débouché de la fente 6, ceci afin de ne pas gêner l'introduction de la clef 5 dans cette fente.As shown in Figures 2 and 3, when the elements of the cylinder are assembled, the finger 12 is inserted into the slot part 6a which opens out from the flange 7 in the radial extension of the slot 6 of the rotor 4 and thus ensures the rotational connection of the patch 8 with this rotor 4. It is indeed obvious that the finger 12 has a width less than the width of the slot 6 for be able to fit into it with sufficient play. Finger 12 has a height determined to extend into the flange 7, without however coming to the level of the outlet of the slot 6, this so as not to hinder the introduction of the key 5 in this slot.

    Cette pastille anti-perçage est obtenue par frittage ou moulage MIM, dans un alliage métallique dur, mais ayant une résistance au cisaillement inférieure à celle de l'acier. Par exemple, elle est réalisée en acier FN08 ayant une résistance Rm supérieure à 500 MPa, un allongement supérieur à 15 % et une dureté HV10 de 180. Cette pastille présente, par rapport aux pastilles existantes, l'avantage de pouvoir se monter sur la plupart des ensembles rotor-faux stator des cylindres existants, soit en première ou deuxième monte, soit lors de réparations après effraction. La base du doigt augmente la section résistante de la matière entre les bords de la fente 9 de la pastille et supprime pratiquement tout risque d'effraction par tentative d'élargissement de cette fente. Lors d'une tentative d'effraction par entraínement en rotation de la pastille, le doigt 12 peut casser en libérant la pastille qui, en pivotant dans l'enveloppe, diminue la prise de l'outil utilisé et réduit les risques d'effraction.This anti-drilling disc is obtained by sintering or MIM molding, in a hard metal alloy, but having a shear strength lower than that of steel. For example, it is made of FN08 steel having a resistance Rm greater than 500 MPa, an elongation greater than 15% and a hardness HV10 of 180. This tablet has, compared to the pellets the advantage of being able to be mounted on most rotor-false assemblies stator of existing cylinders, either as original or retrofit, or during repairs after break-in. The base of the finger increases the section resistant of the material between the edges of the slot 9 of the patch and removes practically any risk of break-in by attempting to widen this slot. During an attempted break-in by driving in rotation of the tablet, finger 12 can break by releasing the tablet which, by pivoting in the envelope, reduces the grip of the tool used and reduces the risk of break-ins.

    La forme d'exécution des figures 4 à 7 met en oeuvre une pastille 8a, réalisée dans le même matériau et de la même façon que celle 8 pour fournir les mêmes dureté et résistance. Elle se différencie de la forme d'exécution précédente par les points suivants :

    • le faux stator 3a est monté dans un corps 17 qui est calé dans une enveloppe-cuirasse 13,
    • la collerette 7a du rotor 4a s'insère dans un alésage 20 d'un collet 14 du corps 17,
    • la pastille antiperçage 8a est montée libre en rotation dans un alésage de la cuirasse 13 et comporte une collerette interne 15a qui, disposée dans un alésage 21 de la cuirasse, est calée en translation entre le corps 17 et le retour de l'enveloppe-cuirasse 13.
    The embodiment of Figures 4 to 7 uses a pellet 8a, made of the same material and in the same way as that 8 to provide the same hardness and resistance. It differs from the previous embodiment by the following points:
    • the false stator 3a is mounted in a body 17 which is wedged in an armor-shell 13,
    • the collar 7a of the rotor 4a is inserted into a bore 20 of a collar 14 of the body 17,
    • the anti-drilling pad 8a is mounted to rotate freely in a bore in the breastplate 13 and has an internal collar 15a which, disposed in a bore 21 of the breastplate, is wedged in translation between the body 17 and the return of the armor-shell 13.

    Comme montré plus en détails à la figure 7, le doigt 12a est composé d'une partie 112, saillant radialement vers l'extérieur de la pastille 8a, dans la fente 9 de cette pastille et dans le prolongement de la partie postérieure de cette pastille, et d'une partie extrême 113, coudée par rapport à la première partie en direction de l'arrière et, dans la forme d'exécution représentée, coudée à sensiblement 90°.As shown in more detail in Figure 7, the finger 12a is composed of a part 112, projecting radially outwards from the patch 8a, in the slot 9 of this patch and in the extension of the part posterior of this patch, and of an extreme part 113, bent with respect to the first part towards the rear and, in the form of execution shown, angled at substantially 90 °.

    La partie 112 s'insère dans un intervalle S qui est aménagé entre la face en bout du corps 17, sensiblement coplanaire à la face en bout du rotor 4a, et le talon 115 de la clé 5, par exemple en réduisant par meulage la longueur de ce talon par rapport à celui d'une clé normale pour ce type de cylindre.The part 112 is inserted in an interval S which is arranged between the end face of the body 17, substantially coplanar with the end face of the rotor 4a, and the heel 115 of the key 5, for example by reducing by grinding the length of this heel compared to that of a normal key for this type of cylinder.

    Quant à la partie 113, qui est en saillie par rapport à la face postérieure de la pastille 8a, elle s'insère dans la partie 6a de la fente 6 du rotor entre la collerette 14 du corps 17 et le passage de la clé matérialisé par le trait mixte T.As for the part 113, which projects from the face posterior of the patch 8a, it is inserted in the part 6a of the slot 6 of the rotor between the flange 14 of the body 17 and the passage of the key materialized by the mixed line T.

    Comme dans la forme d'exécution précédente, le doigt 12a de la pastille anti perçage est lié en rotation au rotor 4a sans gêner le passage de la clé, et peut se rompre pour redonner une liberté de rotation à la pastille, par exemple en cas de tentative d'effraction par un effort générant un couple de rotation.As in the previous embodiment, the finger 12a of the anti drilling hole is linked in rotation to the rotor 4a without hindering the passage of the key, and can break to give freedom of rotation to the pellet, by example in the event of an attempted break-in by an effort generating a couple of rotation.

    2. Lock cylinder with pick-resistant disc as claimed in claim 1, characterised in that the finger (12) projects inside a ring (10) protecting the false stator (3) on the rear part of the disc, this ring forming a seating which caps the collar (7) of the rotor (4).
    3. Lock cylinder with pick-resistant disc as claimed in claim 1, characterised in that the finger (12a) consists of a part (112) joined to the disc which projects radially towards the exterior in the extension of the rear part of the disc and in a space (S) formed between the collar (7a) of the rotor (3a) and the heel (115) of the key (5a), and an end part (113) which, relative to the first part, is bent in the direction of the collar (7a) to form a projection which, extending beyond the rear face of the disc (8a), penetrates the part of the slot (6a) disposed in the collar (7a) of the rotor (4a).
