Abstract

The invention relates to a safety lock with a pivoting stator, of the type comprising a rotor (1) rotating in a stator (2) by means of a notched key interacting with lock members, such as followers or pairs of pistons returned by a spring, the said stator being mounted pivotably in a body and being indexed elastically relative to this body, the said rotor driving a lock control finger (7) which, when the stator pivots together with the rotor as a result of the insertion of the wrong key or a tool, is rendered incapable of driving the lock because of the shift of its axis of rotation made coaxial with the common axis of rotation of the rotor and stator, the said finger being fixed to a slide (6) movable in a diametral groove (5) of the rotor and returned elastically outwards. The lock according to the invention is characterised in that the stator (2) is equipped with a radial orifice (11) which, when the lock is in the position of rest, extends the said radial groove (5) of the rotor (1), and in that a presser (14) returned elastically towards the inside of the stator (2) closes off the said orifice (11) when the stator (2) is in the position of rest. The method is used in lock-making. <IMAGE>

Description

L'invention concerne une serrure de sûreté à stator pivotant du type comprenant un rotor tourillonnant dans un stator au moyen d'une clé crantée coopérant avec des organes de verrouil­lage tels que paillettes ou couples de pistons rappelés par ressorts, ledit stator étant monté pivotant dans un corps et indexé élastiquement par rapport à ce corps, ledit rotor en­traînant un doigt de commande de la serrure qui, lorsque le stator pivote avec le rotor du fait de l'introduction d'une fausse clé ou d'un outil, est mis hors d'état d'entraîner la serrure du fait du déplacement de son axe de rotation rendu coaxial à l'axe commun de rotation rotor - stator ou du fait d'une translation radiale dudit doigt.The invention relates to a safety lock with a pivoting stator of the type comprising a rotor swiveling in a stator by means of a notched key cooperating with locking members such as flakes or pairs of pistons returned by springs, said stator being pivotally mounted in a body and indexed elastically relative to this body, said rotor driving a lock control finger which, when the stator pivots with the rotor due to the introduction of a false key or a tool, is put out state of driving the lock due to the displacement of its axis of rotation made coaxial with the common axis of rotation rotor - stator or due to a radial translation of said finger.

Une telle serrure de sûreté, connue par EP-0 151 081, présente une très haute sécurité contre les tentatives de fraude par forçage en rotation et est également difficile à violer par palpage des organes de verrouillage. En effet, tout couple appliqué au rotor entraîne celui-ci en rotation avec le sta­tor et le doigt de commande de la serrure est rendu inactif.Such a safety lock, known from EP-0 151 081, has very high security against fraud attempts by rotation forcing and is also difficult to breach by probing the locking members. Indeed, any torque applied to the rotor causes it to rotate with the stator and the lock control finger is made inactive.

Diverses formes d'exécution d'une telle serrure ont été propo­sées. On a en particulier rendu le rotor, ou une portion de celui-ci, coulissant par rapport au stator de manière à pro­duire une telle translation axiale du doigt d'entraînement. Une telle solution est compliquée, encombrante en longueur et soumet les composants à des usures importantes du fait des multiples translations auxquelles est soumis le rotor ou une partie de celui-ci.Various embodiments of such a lock have been proposed. In particular, the rotor, or a portion thereof, has been made to slide relative to the stator so as to produce such an axial translation of the drive finger. Such a solution is complicated, bulky in length and subjects the components to significant wear due to the multiple translations to which the rotor or part of it is subjected.

Dans FR-A-2583 813, on a proposé que le doigt d'entraînement soit solidaire d'un coulisseau lui-même solidaire en rotation du rotor et coopérant par effet de came avec un évidement du stator et étant rappelé par ressort vers cet évidement. Cette solution, si elle permet de construire une serrure courte, présente cependant certains défauts. En effet, la coopération du doigt par effet de came avec un évidement du stator peut entraîner des coincements, l'angle de l'évidement et de la portion coopérante du doigt étant critique.In FR-A-2583 813, it has been proposed that the drive finger is integral with a slide which is itself integral in rotation with the rotor and cooperating by cam effect with a recess in the stator and being returned by spring towards this recess . This solution, if it allows to build a short lock, has some faults, however. Indeed, the cooperation of the finger by cam effect with a recess in the stator can cause jamming, the angle of the recess and of the cooperating portion of the finger being critical.

La présente invention vise à perfectionner une serrure du type décrit à l'introduction, dans laquelle ledit doigt est solidaire d'un coulisseau mobile dans une rainure diamétrale du rotor et rappelé élastiquement vers l'extérieur, de manière à éviter tout risque de coincement et toute usure prématurée de la ser­rure.The present invention aims to improve a lock of the type described in the introduction, in which said finger is integral with a movable slide in a diametrical groove of the rotor and resiliently biased outward, so as to avoid any risk of jamming and any premature wear of the lock.

A cet effet, la serrure selon l'invention est caractérisée par le fait que le stator est muni d'une ouverture radiale qui, en position de repos de la serrure, prolonge ladite rainure radiale du rotor et qu'un presseur rappelé élastiquement vers l'intérieur du stator obture ladite ouverture en position de repos du stator.To this end, the lock according to the invention is characterized in that the stator is provided with a radial opening which, in the rest position of the lock, extends said radial groove of the rotor and that a presser resiliently biased towards the inside the stator closes said opening in the rest position of the stator.

En fonctionnement normal de la serrure, le presseur efface le coulisseau à l'intérieur du rotor, au début de la rotation, et ce coulisseau est ensuite maintenu par la paroi interne du stator. En cas de tentative de viol, le stator pivote avec le rotor et le bord de l'ouverture soulève le presseur de sorte que, après rotation d'un certain angle, l'ouverture du stator, qui reste dans le prolongement de la rainure du rotor, n'est plus obturée par le presseur et le coulisseau s'échappe à tra­vers l'ouverture, produisant la translation radiale du doigt qu'il porte et qui devient ainsi coaxial à l'ensemble rotor-­stator.In normal operation of the lock, the presser clears the slide inside the rotor, at the start of rotation, and this slide is then held by the internal wall of the stator. In the event of an attempted rape, the stator pivots with the rotor and the edge of the opening lifts the presser so that, after rotation by a certain angle, the opening of the stator, which remains in the extension of the groove of the rotor, is no longer closed by the presser and the slide escapes through the opening, producing the radial translation of the finger it carries and which thus becomes coaxial with the rotor-stator assembly.

Une caractéristique importante de l'invention réside en ce que le presseur coopérant avec l'ouverture du stator forme l'indexation angulaire de la serrure, ce qui permet une con­struction particulièrement simple, compacte et économique.An important characteristic of the invention resides in that the presser cooperating with the opening of the stator forms the angular indexing of the lock, which allows a particularly simple, compact and economical construction.

La serrure de sûreté représentée dans les dessins annexés à titre d'exemple est constituée par un rotor 1 pouvant tourner dans un stator coaxial 2, sans déplacement latéral, sous l'ac­tion de la clé d'ouverture. Le stator 2 peut tourner, sans dé­placement latéral, à l'intérieur d'un manchon ou corps 3. Le rotor 1 est prolongé par un plateau cylindrique 4 portant une rainure borgne 5 dans laquelle circule un coulisseau 6 portant un doigt d'entrainement 7 qui lui est perpendiculaire. Le cou­lisseau 6 est creux et contient un ressort de compression 8 qui prend appui, d'une part sur l'extrémité borgne de la rai­nure 5 et d'autre part sur le fond du coulisseau 6 pour faire saillir ledit coulisseau 6 hors de la rainure 5.The security lock shown in the accompanying drawings by way of example is constituted by a rotor 1 which can rotate in a coaxial stator 2, without lateral displacement, under the action of the opening key. The stator 2 can rotate, without lateral displacement, inside a sleeve or body 3. The rotor 1 is extended by a cylindrical plate 4 carrying a blind groove 5 in which a slide 6 carrying a drive finger 7 circulates which is perpendicular to it. The slide 6 is hollow and contains a compression spring 8 which rests, on the one hand on the blind end of the groove 5 and on the other hand on the bottom of the slide 6 to project said slide 6 out of the groove 5.

Une plaque 9 est fixée au moyen de vis 10 sur la face ouverte du plateau 4 de manière à maintenir le coulisseau 6 à l'inté­rieur de la rainure 5. Une découpe pratiquée dans la plaque 9 autorise le déplacement du doigt d'entrainement 7 du centre à la périphérie du plateau 4.A plate 9 is fixed by means of screws 10 on the open face of the plate 4 so as to hold the slide 6 inside the groove 5. A cutout made in the plate 9 allows the movement of the drive finger 7 of the center on the periphery of the plateau 4.

La partie arrière du stator 2 comporte une creusure 12 entou­rant complètement le plateau 4. Elle est fraisée selon un plan parallèle à l'axe X X du rotor de manière à produire une ouver­ture 11 de la largeur du coulisseau 6. Une ouverture 13 est pratiquée dans le manchon 3 pour laisser passer un presseur 14 poussé par un ressort - lame 15.The rear part of the stator 2 has a recess 12 completely surrounding the plate 4. It is milled along a plane parallel to the axis XX of the rotor so as to produce an opening 11 of the width of the slide 6. An opening 13 is made in the sleeve 3 for passing a presser 14 pushed by a leaf spring 15.

En position de repos, le presseur 14 est appliqué sur la par­tie fraisée 11 du stator 2, le ressort 15 ayant prépondérance sur le ressort 8 du coulisseau 6 de manière que ledit coulis­seau 6 soit maintenu tout entier à l'intérieur de la rainure 5.In the rest position, the presser 14 is applied to the milled part 11 of the stator 2, the spring 15 having a preponderance on the spring 8 of the slider 6 so that said slider 6 is kept entirely inside the groove 5.

Une came batteuse 16 est appliquée intérieurement contre l'ex­tremité fermée du manchon 3. Elle porte un téton 17 qui s'en­gage dans un trou à son diamètre pratiqué dans la face arrière du manchon 3 sur l'axe X X. Elle porte également un prolonge­ment qui sort par une ouverture 19 pratiquée dans le manchon 3. La came batteuse 16 porte sur sa face en regard du plateau 4 une ouverture 18 dans laquelle se déplace le doigt 7. Un ca­puchon 20 coiffe le manchon 3 sur lequel il est fixé d'une manière quelconque, pour maintenir l'ensemble rotor - stator à l'intérieur du manchon 3.A threshing cam 16 is applied internally against the closed end of the sleeve 3. It carries a stud 17 which engages in a hole with its diameter made in the rear face of the sleeve 3 on the axis X X. It also carries a extension which comes out through an opening 19 made in the sleeve 3. The threshing cam 16 carries on its face opposite the plate 4 an opening 18 in which the finger moves. A cap 20 covers the sleeve 3 on which it is fixed d '' in any way, to maintain the rotor - stator assembly inside the sleeve 3.

Le fonctionnement normal est le suivant: le stator 2 étant immobilisé par le presseur14, la clé conforme permet la rota­tion du rotor et, par conséquent, celle du plateau 4. Le cou­lisseau 6 rencontre la surface intérieure fixe du stator 2 fermée par le presseur 14 et ne peut sortir de sorte que le doigt 7 effectue un parcours circulaire autour de l'axe X X dont il est excentré. Dans l'exemple de la figure 1, le doigt 7 entraine la came batteuse 16 dès qu'il entre en contact avec la paroi de l'ouverture 18, dans un sens ou dans l'autre sui­vant le sens de rotation de la clé. Dans cette disposition qui correspond à une serrure de portière d'automobile, on a prévu une course de 60 degrés de la came batteuse 16 limitée par l'ouverture 18 élargie pour permettre à la came batteuse 16 le débattement necessaire pour la fermeture automatique de la portière.Normal operation is as follows: the stator 2 being immobilized by the presser 14, the conforming key allows the rotation of the rotor and, consequently, that of the plate 4. The slide 6 meets the fixed inner surface of the stator 2 closed by the presser 14 and can not come out so that the finger 7 performs a circular path around the axis XX of which it is eccentric. In the example of Figure 1, the finger 7 drives the cam 16 as soon as it comes into contact with the wall of the opening 18, in one direction or the other depending on the direction of rotation of the key. In this arrangement which corresponds to an automobile door lock, a 60 degree stroke of the threshing cam 16 is provided, limited by the opening 18 widened to allow the threshing cam 16 the clearance necessary for the automatic closing of the door.

La commande de la timonerie d'ouverture s'effectue à partir du prolongement extérieur de la came batteuse 16.The control of the opening linkage is effected from the external extension of the threshing cam 16.

Quand le doigt d'entrainement 7 doit effectuer une rotation de 360 degrés, par exemple pour actionner un pène, le dispositif est réalisé suivant l'exemple de la figure 3. La came batteuse est remplacée par une pièce rotative 22 tournant sur l'axe X X . Elle porte une rainure 25 dans laquelle s'en­gage le doigt d'entrainement 7, pratiquée à partir de l'axe X X sur une longueur en rapport avec l'amplitude du mouvement du doigt d'entrainement 7. Une plaque 23 est fixée par des vis 24 sur la pièce 22 pour empécher son déplacement latéral. La plaque 23 porte un doigt 21 excentré par rapport à l'axe X X.When the training finger 7 must rotate 360 degrees, for example to actuate a bolt, the device is produced according to the example of FIG. 3. The threshing cam is replaced by a rotary part 22 rotating on the axis XX. It carries a groove 25 in which engages the drive finger 7, made from the axis XX over a length related to the amplitude of movement of the drive finger 7. A plate 23 is fixed by screw 24 on the part 22 to prevent its lateral movement. The plate 23 carries a finger 21 eccentric with respect to the axis X X.

Le fonctionnement normal s'apparente au cas précédent. Le doigt d'entrainement 7, agissant comme une pièce de transmission, fait tourner la pièce 22 autour de l'axe X X et le doigt 21 agissant comme doigt d'entrainement est utilisé pour actionner les barbes d'un pène.Normal operation is similar to the previous case. The drive finger 7, acting as a transmission part, rotates the part 22 around the axis X X and the finger 21 acting as the drive finger is used to actuate the barbs of a bolt.

En cas d'action frauduleuse par forçage ou perçage, le rotor 1 entraine le stator 2 par les organes de verrouillage tels que pistons ou paillettes. En tournant, le stator 2 provoque le soulèvement du presseur 14 et la libération du coulisseau 6 poussé par le ressort 8. D'une part le doigt 7, solidaire du coulisseau 6, se déplace vers l'axe X X, sa course étant limitée par la découpe de la plaque 9 de sorte que le débattement du doigt 7 étant nul ou insuffisant, ne peut entrainer, soit la came batteuse 16, soit la pièce 22. D'autre part, le rotor et le stator restent solidaires par le coulisseau entré dans la découpe du stator de sorte que, en cas de fausse manoeuvre ou de fraude déjà indiquée, il ne peut avoir désolidarisation entre rotor et stator jusqu'à l'achèvement du tour complet.In the event of fraudulent action by forcing or drilling, the rotor 1 drives the stator 2 by the locking members such as pistons or flakes. By turning, the stator 2 causes the lifting of the presser 14 and the release of the slider 6 pushed by the spring 8. On the one hand the finger 7, integral with the slider 6, moves towards the axis XX, its stroke being limited by the cutting of the plate 9 so that the clearance of the finger 7 being zero or insufficient, cannot cause either the threshing cam 16 or the part 22. On the other hand, the rotor and the stator remain integral by the slider entered in the cutout of the stator so that, in the event of a false operation or fraud already indicated, it cannot have separation between rotor and stator until the completion of the complete turn.

Après cessation de la tentative de fraude, la serrure peut fonctionner normalement avec le clé conforme, même à partir d'une position autre que la position initiale, l'achèvement de la rotation de l'ensemble rotor-stator assurant le retour du coulisseau 6 à l'intérieur de la rainure 5 par l'action du presseur 14.After cessation of the attempted fraud, the lock can operate normally with the compliant key, even from a position other than the initial position, the completion of the rotation of the rotor-stator assembly ensuring the return of the slide 6 inside the groove 5 by the action of the presser 14.

Le presseur 14 représenté à la figure 1 peut être réalisé en matériau synthétique collé sur le manchon 3 ou venu de mou­lage avec lui. Il peut être en acier à ressort et fixé d'une manière quelconque sur le manchon 3. Le presseur 14 peut aussi être réalisé, suivant la figure 9, au moyen d'un ressort à lame 26 prenant appui sur la face arrière du manchon 3. Dans une autre variante (figure 10), le presseur 14 est solidaire d'une plaque coulissante 27 extérieure au manchon 3 et rappe­lée en position basse par un ressort spiral 28 agissant sur les butées 29 et 30 situées sur le manchon et sur la pièce coulis­sante 27.The presser 14 shown in Figure 1 can be made of synthetic material bonded to the sleeve 3 or molded therewith. It can be made of spring steel and fixed in any way on the sleeve 3. The presser 14 can also be produced, according to FIG. 9, by means of a leaf spring 26 bearing on the rear face of the sleeve 3 In another variant (FIG. 10), the presser 14 is secured to a sliding plate 27 external to the sleeve 3 and returned to the low position by a spiral spring 28 acting on the stops 29 and 30 located on the sleeve and on the workpiece. sliding 27.

Le presseur peut accessoirement comporter un dispositif visant à indexer avec plus de précision la position du rotor en vue de faciliter le retrait de la clé. Suivant la figure 11, le presseur 14 porte un léger évidement 31 dans lequel se loge l'extrémité arrondie du coulisseau. L'indexage ainsi réalisé du coulisseau entraine celui du rotor.The presser may incidentally include a device aimed at indexing the position of the rotor more precisely in order to facilitate the removal of the key. According to Figure 11, the presser 14 carries a slight recess 31 in which is housed the rounded end of the slide. The indexing thus produced of the slide leads to that of the rotor.

Suivant la figure 12 le fraisage du stator peut être réalisé suivant deux plans obliques, la forme du presseur étant adap­tée à la découpe ainsi réalisée, pour permettre son soulèvement au cours de la rotation du stator. Cette disposition autorise un mouvement plus rapide du coulisseau.According to FIG. 12, the milling of the stator can be carried out in two oblique planes, the shape of the presser being adapted to the cut thus produced, to allow it to be raised during the rotation of the stator. This arrangement allows faster movement of the slide.

L'invention s'applique également aux serrures dont le rotor est excentré par rapport au stator. Suivant la figure 13, le plateau cylindrique 4 tourne dans l'évidement 12 du stator 2. L'usinage du stator 2 autour de l'évidement 12 est excentré de manière à élargir la surface d'appui 32 du presseur 14 pour assurer une meilleure immobilisation du stator.The invention also applies to locks whose rotor is eccentric relative to the stator. According to Figure 13, the cylindrical plate 4 rotates in the recess 12 of the stator 2. The machining of the stator 2 around the recess 12 is eccentric so as to widen the bearing surface 32 of the presser 14 to ensure better immobilization of the stator.
