La présente invention concerne une serrure à clé plate, et plus particulièrement une serrure à clé plate à butée de clé active.The present invention relates to a flat key lock, and more particularly to a flat key lock with an active key stop.

Le document EP 2 407 616 décrit une serrure à clé plate comportant, au voisinage du fond du canal de clé, une butée de clé active, sollicitée par ressort vers l'extérieur du rotor dans une encoche du stator, et assurant le blocage du rotor en l'absence de clé. Cette butée de clé active comporte une rampe et la clé comporte une rampe correspondante. En fin d'introduction de la clé dans le canal de clé, les deux rampes coopèrent pour assurer le déplacement de la butée de clé active de la position de verrouillage à la position de libération du rotor.The document EP 2 407 616 describes a lock with a flat key comprising, in the vicinity of the bottom of the key channel, an active key abutment, biased by a spring towards the outside of the rotor in a notch of the stator, and ensuring the locking of the rotor in the absence of a key . This active key stop has a ramp and the key has a corresponding ramp. At the end of the introduction of the key into the key channel, the two ramps cooperate to ensure the movement of the active key stop from the locking position to the release position of the rotor.

Un but de la présente invention est d'apporter une sécurité supplémentaire à une serrure de clé plate à butée de clé active.An object of the present invention is to provide additional security to a flat key lock with an active key stop.

L'invention a pour objet une serrure à clé plate, à butée de clé active disposée dans un logement de rotor au voisinage du fond du canal de clé, sollicitée vers une encoche de stator en l'absence de clé pour assurer un verrouillage du rotor, et comportant une rampe coopérant avec une rampe correspondante de la clé pour ramener, en fin d'introduction de la clé dans le canal de clé, la butée de clé active de la position de verrouillage du rotor vers la position de libération du rotor, caractérisée en ce que :

  • la butée de clé active comporte, à l'opposé de sa rampe dans le sens de progression de la clé, une excroissance dirigée vers le canal de clé, et
  • la clé comporte un usinage pour recevoir ladite excroissance lorsque la butée de clé active est ramenée en position de libération du rotor.
The subject of the invention is a lock with a flat key, with an active key stop arranged in a rotor housing in the vicinity of the bottom of the key channel, urged towards a notch in the stator in the absence of a key to ensure locking of the rotor , and comprising a ramp cooperating with a corresponding ramp of the key to return, at the end of the introduction of the key into the key channel, the active key stop from the locking position of the rotor to the releasing position of the rotor, characterized in that:
  • the active key stop comprises, opposite its ramp in the direction of progression of the key, a protrusion directed towards the key channel, and
  • the key includes machining to receive said protrusion when the active key stop is returned to the rotor release position.

Selon un mode de réalisation, la forme de l'excroissance et celle de l'usinage sont compatibles entre elles.According to one embodiment, the shape of the protrusion and that of the machining are mutually compatible.

Selon un mode de réalisation, la rampe de la clé a une longueur suffisante pour, par coopération avec la rampe de la butée de clé active, ramener, en fin d'introduction de la clé dans le canal de clé, la butée de clé active jusqu'à la position de libération du rotor.According to one embodiment, the ramp of the key has a sufficient length to, by cooperation with the ramp of the active key stop, bring back, at the end of the introduction of the key into the key channel, the active key stop to the rotor release position.

Selon un mode de réalisation, la rampe de la clé n'a pas une longueur suffisante pour ramener la butée de clé active jusqu'à la position de libération du rotor, et la clé comporte, dans l'usinage, un aimant assurant, par attraction de l'excroissance, l'achèvement du déplacement de la butée de clé active jusqu'à la position de libération du rotor.According to one embodiment, the ramp of the key does not have a sufficient length to bring the active key abutment back to the release position of the rotor, and the key comprises, in the machining, a magnet ensuring, by attraction of the protrusion, the completion of the movement of the active key stop to the release position of the rotor.

Selon un mode de réalisation, la butée de clé active est sollicitée vers le stator, en position de verrouillage du rotor, par des ressorts logés dans le rotor.According to one embodiment, the active key stop is urged towards the stator, in the rotor locking position, by springs housed in the rotor.

Selon un mode de réalisation, la butée de clé active est sollicitée vers le stator, en position de verrouillage du rotor, par un aimant logé dans le stator.According to one embodiment, the active key stop is urged towards the stator, in the rotor locking position, by a magnet housed in the stator.

Une serrure à clé plate conforme à l'invention comprend, dans l'exemple de réalisation représenté (Fig. 1), un cylindre 1 à embase unique et deux stators 2, pour chaque stator 2 un rotor 3, et une clé 4. Dans un autre exemple de réalisation, la serrure comprend un stator unique. Une butée de clé active 5 est disposée dans un logement 6 du rotor 3.A flat key lock according to the invention comprises, in the embodiment shown ( Fig. 1 ), a cylinder 1 with a single base and two stators 2, for each stator 2 a rotor 3, and a key 4. In another exemplary embodiment, the lock comprises a single stator. An active key stop 5 is placed in a housing 6 of the rotor 3.

La butée de clé active 5 comporte (Fig. 2), un corps central 7 et deux ailes 8, 9 portant chacune un tube, respectivement 10, 11, destiné au guidage et à loger un ressort 12, 13.The active key stop 5 has ( Fig. 2 ), a central body 7 and two wings 8, 9 each carrying a tube, respectively 10, 11, intended for guiding and housing a spring 12, 13.

Le corps central 7 porte, du côté recevant la clé 4, une rampe 14, et du côté opposé une excroissance 15 dirigée vers l'axe du rotor 3. La tige de la clé 4 présente (Fig. 3), au voisinage de son extrémité, une rampe 16 destinée à coopérer avec la rampe 14 de la butée de clé active 5 pour assurer le passage de la butée de clé active 5 de sa position de verrouillage du rotor vers sa position de libération du rotor.The central body 7 carries, on the side receiving the key 4, a ramp 14, and on the opposite side a protrusion 15 directed towards the axis of the rotor 3. The stem of the key 4 has ( Fig. 3 ), near its end, a ramp 16 intended to cooperate with the ramp 14 of the active key stop 5 to ensure the passage of the active key stop 5 from its rotor locking position to its rotor release position .

En avant de la rampe 16, sur son profil étroit, la clé 4 présente un usinage latéral 17 destiné à recevoir l'excroissance 15 de la butée de clé active 5. Dans le plan moyen de la clé 4 (Fig. 4 et Fig. 6), avant contact des deux rampes 14 et 16, la butée de clé active 5 est repoussée dans le stator 2 par ses ressorts 12, 13, et elle est en position de verrouillage du rotor 3. En cas de progression de la clé 4, la rampe 16 de la clé 4 coopère avec la rampe 14 de la butée de clé active 5 pour ramener la butée de clé active 5 dans le volume du rotor 3, vers la position de libération du rotor 3. Le déplacement de la butée de clé active 5 entraîne le déplacement de son excroissance 15 dans l'usinage 17 de la clé 4 (Fig. 5 et Fig. 7). Dans l'exemple de réalisation des Fig. 4 à Fig. 7, la rampe 16 de la clé 4 a une longueur suffisante pour, par coopération avec la rampe 14 de la butée de clé active 5, ramener la butée de clé active 5 jusqu'à la position de libération du rotor 3. En fin d'introduction de la clé 4 dans le canal de clé, la butée de clé active 5 est en position de libération du rotor 3 et la clé peut alors tourner et entraîner le rotor 3.In front of the ramp 16, on its narrow profile, the key 4 has a lateral machining 17 intended to receive the protrusion 15 of the active key stop 5. In the middle plane of the key 4 ( Fig. 4 and Fig. 6 ), before contact of the two ramps 14 and 16, the active key stop 5 is pushed back into the stator 2 by its springs 12, 13, and it is in the locking position of the rotor 3. In the event of progression of the key 4, the ramp 16 of the key 4 cooperates with the ramp 14 of the active key stop 5 to bring the active key stop 5 back into the volume of the rotor 3, towards the release position of the rotor 3. The movement of the key stop active 5 causes the displacement of its protrusion 15 in the machining 17 of the key 4 ( Fig. 5 and Fig. 7 ). In the embodiment of the Fig. 4 to Fig. 7 , the ramp 16 of the key 4 has a sufficient length to, by cooperating with the ramp 14 of the active key stop 5, bring the active key stop 5 back to the release position of the rotor 3. At the end of introduction of the key 4 into the key channel, the active key stop 5 is in the release position of the rotor 3 and the key can then turn and drive the rotor 3.

Dans le cas d'utilisation d'une clé à rampe 16 mais dépourvue d'usinage 17, ou dotée d'un usinage de forme inadaptée à l'excroissance 15, la progression de la clé 4 est interrompue. La clé ne peut aller jusqu'à sa butée naturelle et ne peut pas commander la rotation du rotor 3. La forme de l'excroissance est adaptable au goût de chacun, comme la forme de l'usinage. Le seul impératif est que les formes de l'excroissance et de l'usinage soient compatibles entre elles.In the case of use of a ramp key 16 but devoid of machining 17, or provided with a machining of an unsuitable shape to the protrusion 15, the progress of the key 4 is interrupted. The key cannot move to its natural stop and cannot not control the rotation of the rotor 3. The shape of the protrusion is adaptable to everyone's taste, like the shape of the machining. The only imperative is that the shapes of the protuberance and the machining are compatible with each other.

Dans l'exemple de réalisation des Fig. 8 et Fig. 9, la rampe 16 de la clé 4 n'a pas une longueur suffisante pour ramener la butée de clé active 5 jusqu'à la position de libération du rotor 3. La Fig. 8 montre la clé 4 en position introduite dans le canal de clé, et la butée de clé active 5 ramenée vers le canal de clé mais pas suffisamment pour libérer le rotor 3. La clé 4 comporte, dans l'usinage 17, un aimant 18 assurant, par attraction de l'excroissance 15, l'achèvement du déplacement de la butée de clé active 5 jusqu'à la position de libération du rotor 3 (Fig. 9). Ainsi, l'association de la rampe 16 de la clé et de l'aimant 18 logé dans l'usinage 17 de la clé 4, assure le déplacement de la butée de clé active 5 depuis sa position de verrouillage du rotor 3 jusqu'à sa position de libération du rotor 3.In the embodiment of the Fig. 8 and Figs. 9 , the ramp 16 of the key 4 does not have a sufficient length to bring the active key stop 5 back to the release position of the rotor 3. The Fig. 8 shows the key 4 in the position introduced into the key channel, and the active key stop 5 brought back towards the key channel but not sufficiently to release the rotor 3. The key 4 comprises, in the machining 17, a magnet 18 ensuring , by attraction of the protrusion 15, the completion of the movement of the active key stop 5 to the release position of the rotor 3 ( Fig. 9 ). Thus, the association of the ramp 16 of the key and the magnet 18 housed in the machining 17 of the key 4, ensures the movement of the active key stop 5 from its locking position of the rotor 3 until its rotor release position 3.

Pour assurer sa fonction de verrouillage du rotor 3 en l'absence de clé 4, la butée de clé active 5 doit être sollicitée vers le stator 2. Dans l'exemple de réalisation des Fig. 1 à Fig. 9, la butée de clé active 5 est sollicitée vers le stator 2 par des ressorts 12, 13, logés dans le rotor 3, dans les tubes 10, 11 portés par la butée de clé active 5.To ensure its function of locking the rotor 3 in the absence of key 4, the active key stop 5 must be urged towards the stator 2. In the embodiment of the Fig. 1 to Figs. 9 , the active key stop 5 is urged towards the stator 2 by springs 12, 13, housed in the rotor 3, in the tubes 10, 11 carried by the active key stop 5.

Dans l'exemple de réalisation des Fig. 10 et Fig. 11, la butée de clé active 5 est sollicitée vers le stator 2 par un aimant 19 logé dans le stator 2.In the embodiment of the Fig. 10 and Figs. 11 , the active key stop 5 is urged towards the stator 2 by a magnet 19 housed in the stator 2.

Sur la Fig. 10, en l'absence de clé, la buté de clé active 5 est attirée par l'aimant 19 et assure le verrouillage du rotor 3. Sur la Fig. 11, en présence de la clé, la butée de clé active 5 est ramenée dans le rotor 3, en position de libération du rotor .3.On the Fig. 10 , in the absence of a key, the active key stop 5 is attracted by the magnet 19 and ensures the locking of the rotor 3. On the Fig. 11 , in the presence of the key, the active key stop 5 is brought back into the rotor 3, in the release position of the rotor .3.
