Description

La présente invention concerne les clés pour serrures à barillets et se rapporte plus particulièrement aux clés du type comportant au moins un poussoir mobile, déplaçable par rapport au corps de clé selon une course limitée, ledit poussoir étant destiné à coopérer avec un organe de positionnement porté par le rotor du barillet de façon à faire saillie par rapport au contour extérieur de la clé et à pousser une goupille mobile prévue dans le rotor vers une position libérant en rotation le rotor du barillet par rapport à son stator.The present invention relates to keys for cylinder locks and relates more particularly to keys of the type comprising at least one movable pusher, movable relative to the key body according to a stroke limited, said pusher being intended to cooperate with a positioning member carried by the barrel rotor so as to protrude from the outer contour of the key and push a movable pin provided in the rotor to a position releasing the rotor from rotation barrel relative to its stator.

Une telle clé est par exemple connue d'après le brevet FR.2 521 201.Such a key is for example known from the Patent FR.2 521 201.

On connaít par ailleurs d'après WO-A-91 10795, une clé à barillet de sûreté de manoeuvre d'une serrure, dont le corps de clé de forme allongée destiné à pénétrer dans un logement de clé d'un rotor de barillet est pourvu de moyens d'actionnement destinés à coopérer avec un organe de positionnement pour actionner au moins une goupille mobile du rotor, dans une position permettant la rotation du rotor du barillet par rapport au stator de celui-ci. Les moyens d'actionnement de la goupille sont constitués par deux poussoirs montés déplaçables en translation chacun dans un trou débouchant d'une part dans un canal ménagé dans la clé pour une tige de positionnement fixe solidaire du stator et d'autre part, sur la surface latérale extérieure du corps de clé.We also know from WO-A-91 10795, a safety key cylinder for operating a lock, of which the elongated key body intended to penetrate into a key housing of a barrel rotor is provided with actuating means intended to cooperate with a positioning for actuating at least one movable pin of the rotor, in a position allowing rotation of the rotor of the barrel relative to the stator thereof. Ways actuation of the pin consist of two mounted pushers displaceable in translation each in a hole opening on the one hand into a channel in the key for a fixed positioning rod integral with the stator and on the other hand, on the outer lateral surface of the body of key.

La clé décrite dans le brevet FR.2 521 201 comporte un logement pour le poussoir mobile pratiqué dans le plan moyen du corps de clé et débouchant sur les deux chants longitudinaux du corps de clé.The key described in patent FR.2 521 201 comprises a housing for the mobile pusher in the plane key body and leading to the two edges of the key body.

Une saignée nécessaire au passage de l'organe de positionnement qui fait saillie à l'intérieur du logement de clé est ménagé dans les chants longitudinaux du corps de clé. A bleeding necessary for the passage of the organ of protruding positioning inside the housing key is provided in the longitudinal edges of the body of key.

En conséquence, la fabrication d'une clé de ce type est rendue compliquée en raison de la nécessité de pratiquer lesdites saignées et limite les possibilités d'utilisation des chants de la clé pour y réaliser des profils d'actionnement des goupilles du barillet.As a result, making a key of this type is made complicated because of the need to practice said bleeding and limit the possibilities using the edges of the key to make actuation profiles of the barrel pins.

L'invention vise à remédier aux inconvénients de ce type de clé en créant une clé qui tout étant pourvue de moyens mécaniques mobiles de déblocage d'une goupille d'immobilisation en rotation du rotor du barillet, présente des chants susceptibles de recevoir sur toute leur surface des profils d'actionnement des goupilles du cylindre.The invention aims to remedy the drawbacks of this type of key by creating a key which all being provided with movable mechanical means for unlocking a pin of immobilization in rotation of the barrel rotor, present songs likely to receive over their entire surface of the actuation profiles of the pins of the cylinder.

Elle a donc pour objet une clé à barillet de sûreté de manoeuvre d'une serrure, le corps de clé de forme allongée destiné à pénétrer dans un logement de clé du rotor du barillet étant pourvu de moyens d'actionnement destinés à coopérer avec un organe de positionnement pour actionner au moins une goupille mobile de rotor dans une position permettant la rotation du rotor du barillet par rapport au stator de celui-ci, caractérisée en ce que les moyens d'actionnement de la goupille sont constitués par au moins deux poussoirs montés déplaçables en translation dans au moins deux branches d'une fourche d'extrémité de la clé, l'intervalle entre les branches de la fourche étant destiné à recevoir l'organe de positionnement lors de l'engagement de la clé dans le rotor du barillet pour provoquer le déplacement de ladite goupille par l'un des poussoirs.It therefore relates to a cylinder key safe operation of a lock, the key body elongated shape for entering a key housing of the barrel rotor being provided with actuating means intended to cooperate with a positioning member for actuate at least one movable rotor pin in a position allowing rotation of the barrel rotor by compared to the stator thereof, characterized in that the means for actuating the pin consist of at least two pushers mounted movable in translation in at least two branches of an end fork of the key, the interval between the branches of the fork being intended to receive the positioning member during of the engagement of the key in the barrel rotor to cause the displacement of said pin by one of the pushers.

L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant aux dessins annexés, sur lesquels :

  • la Fig.1 est une vue en perspective d'une clé suivant l'invention et d'un organe de positionnement avec lequel elle coopère;
  • la Fig.2 est une vue en coupe transversale, d'un barillet de serrure actionné par la clé de la Fig.1;
  • la Fig.3 est une vue en coupe suivant la ligne 3-3 de la Fig.2; et
  • la Fig.4 est une vue en coupe à plus grande échelle de la clé suivant l'invention montrant les logements pour les poussoirs mobiles.
The invention will be better understood on reading the description which follows, given solely by way of example and made with reference to the appended drawings, in which:
  • Fig.1 is a perspective view of a key according to the invention and of a positioning member with which it cooperates;
  • Fig.2 is a cross-sectional view of a lock cylinder actuated by the key of Fig.1;
  • Fig.3 is a sectional view along line 3-3 of Fig.2; and
  • Fig.4 is a sectional view on a larger scale of the key according to the invention showing the housing for the movable pushers.

La clé représentée à la Fig.l est en fait une ébauche de clé plate dont le corps 1 comporte des rainures longitudinales 2 séparées les unes des autres par des nervures 3 et dont les chants 4 sont plans ou légèrement bombés comme cela apparaít sur la Fig.4.The key shown in Fig. 1 is actually a blank flat key whose body 1 has grooves longitudinal 2 separated from each other by ribs 3 and whose edges 4 are flat or slightly domed as shown in Fig.4.

On voit également sur la figure 4 que le corps de clé comporte sur ses deux grandes faces des profils définis par des rainures et des nervures longitudinales 2 et 3 symétriques par rapport à l'axe de la clé, ce qui rend la clé réversible.We also see in Figure 4 that the body key has profiles on its two large faces defined by grooves and longitudinal ribs 2 and 3 symmetrical about the axis of the key, which makes the key reversible.

A l'extrémité du corps de clé opposée à sa tête de manoeuvre 5, est ménagée une fourche 6 dont les deux branches 7 et 8 comportent des extrémités biseautées 9, 10. Ces extrémités peuvent prendre toute autre forme appropriée.At the end of the key body opposite its head maneuver 5, is provided a fork 6 of which the two branches 7 and 8 have beveled ends 9, 10. These ends can take any other form appropriate.

Les deux branches 7 et 8 définissent une encoche 11 dans laquelle est destinée à venir s'engager une tige 12 représentée en trait mixte formant organe de positionnement pour des poussoirs 13, 14 disposés respectivement dans les branches 7 et 8 de la fourche 6 et dont le rôle sera clairement expliqué en référence aux Fig.2 et 3.The two branches 7 and 8 define a notch 11 in which is intended to engage a rod 12 shown in phantom in the form of a positioning member for pushers 13, 14 arranged respectively in branches 7 and 8 of the fork 6 and whose role will be clearly explained with reference to Figs. 2 and 3.

La Fig.2 montre un barillet ou cylindre de serrure comportant un stator 16 dans lequel est monté à rotation un rotor 17. Le rotor 17 comporte un logement 18 dans lequel est engagé le corps de clé 1.Fig. 2 shows a barrel or cylinder of lock comprising a stator 16 in which is mounted rotation of a rotor 17. The rotor 17 has a housing 18 in which the key body 1 is engaged.

La coupe du barillet de la Fig.2 est réalisée au droit des poussoirs 13 et 14 logés respectivement dans les branches 7 et 8 de la fourche 6 d'extrémité du corps de clé 1.The barrel cut in Fig. 2 is made at right of pushers 13 and 14 housed respectively in the legs 7 and 8 of the fork 6 of the body end key 1.

La clé étant engagée à fond dans le rotor 17, son encoche 11 définie par l'intervalle entre les branches 7 et 8 de la fourche, reçoit la tige transversale 12 formant organe de positionnement montée dans un perçage 20 du rotor 17 s'étendant perpendiculairement au logement 18 pour la clé.The key being fully engaged in the rotor 17, its notch 11 defined by the interval between the branches 7 and 8 of the fork, receives the transverse rod 12 forming a positioning member mounted in a bore 20 of the rotor 17 extending perpendicular to the housing 18 for the key.

Les poussoirs 13 et 14 sont de formes et de dimensions identiques. Chaque poussoir comporte une portion d'extrémité 22 tournée vers l'encoche 11 qui se termine par une pointe chanfreinée 23 destinée à coopérer avec la tige 12 pour assurer le déplacement du poussoir 13 ou 14 vers l'extérieur du contour de la clé.The pushers 13 and 14 are shaped and identical dimensions. Each pusher has a end portion 22 facing the notch 11 which is ends with a chamfered point 23 intended to cooperate with rod 12 to move the pusher 13 or 14 towards the outside of the outline of the key.

Le poussoir comporte en outre une portée intermédiaire 24 plus épaisse et à l'opposé de la pointe 23, une extrémité 25 destinée à coopérer avec une goupille 26 déplaçable en translation dans un canal 27 ménagé dans le rotor 17 et débouchant sur la surface latérale du rotor en regard d'une goupille 28 disposée dans un trou borgne 29 du stator 16 et sollicitée par un ressort 30 représenté à la figure 3, qui, lorsque le rotor 17 est en position de fermeture de la serrure et que la clé est retirée, sollicite la goupille 28 de manière que sa surface latérale soit située de part et d'autre de la surface de contact entre le rotor 17 et le stator 16 et empêche la rotation du rotor.The pusher also has an intermediate reach 24 thicker and opposite the point 23, one end 25 intended to cooperate with a pin 26 displaceable in translation in a channel 27 formed in the rotor 17 and opening onto the lateral surface of the rotor in look of a pin 28 arranged in a blind hole 29 stator 16 and biased by a spring 30 shown at FIG. 3, which, when the rotor 17 is in the position of closing the lock and the key is removed, requests the pin 28 so that its lateral surface either located on either side of the contact surface between rotor 17 and stator 16 and prevents rotation rotor.

Chaque poussoir 13,14 est logé dans un trou 31 débouchant d'une part dans l'encoche 11 et d'autre part sur la surface extérieure de la branche 7,8 correspondante de la fourche 6 et comportant un épaulement 32 coopérant avec un bord de la portée 24 du poussoir pour empêcher que le poussoir ne s'échappe dans l'encoche 11 de la fourche 6 de la clé afin d'éviter tout obstacle à l'engagement de l'organe de positionnement 12 dans l'encoche 11.Each pusher 13,14 is housed in a hole 31 opening on the one hand into the notch 11 and on the other hand on the outer surface of the corresponding branch 7.8 of the fork 6 and having a shoulder 32 cooperating with an edge of the seat 24 of the pusher to prevent that the pusher does not escape into the notch 11 of the fork 6 of the key to avoid any obstacle to the engagement of the positioning member 12 in the notch 11.

Le trou 31 de chaque poussoir a une section égale à celle des portées 24 et son extrémité opposée à l'épaulement 32 et débouchant dans la paroi latérale extérieure de chaque branche 7,8 de la fourche, comporte un sertissage 34 ou tout autre type d'arrêt coopérant avec l'extrémité de la portée 24 opposée à celle située en regard de l'épaulement 32 pour limiter la course du poussoir de manière que seule son extrémité 25 puisse faire saillie hors du contour de la clé et assurer l'actionnement de la goupille 26 du rotor 17. Chaque poussoir a ainsi une course de translation limitée par l'épaulement 32 et le sertissage 34 du trou 31 dans lequel il est logé.The hole 31 of each pusher has a section equal to that of the ranges 24 and its end opposite to the shoulder 32 and opening into the side wall outer of each branch 7,8 of the fork, comprises a crimp 34 or any other type of stop cooperating with the end of the scope 24 opposite to that located in look of the shoulder 32 to limit the stroke of the pusher so that only its end 25 can protrude outside the key outline and ensure actuation of the pin 26 of the rotor 17. Each pusher thus has a translational travel limited by the shoulder 32 and the crimping 34 of the hole 31 in which it is housed.

On voit sur la figure 2 que c'est le poussoir 13 placé dans la branche 7 de la fourche qui est repoussé par la tige 12 du rotor 17 pour assurer le déplacement des goupilles 26 et 28 dans des positions permettant la rotation du rotor.We see in Figure 2 that it is the pusher 13 placed in the branch 7 of the fork which is pushed back by the rod 12 of the rotor 17 to move the pins 26 and 28 in positions allowing the rotor rotation.

L'autre poussoir 14 est en appui avec ou sans jeu contre une partie pleine du stator 16, tandis que sa pointe chanfreinée 23 fait saillie hors de la paroi latérale de l'encoche 11 et se trouve en contact avec ou sans jeu avec la tige 12 à peu près à l'opposé de la zone de contact entre cette tige et la pointe 23 du poussoir 13.The other pusher 14 is in support with or without play against a full part of the stator 16, while its chamfered tip 23 protrudes from the wall side of the notch 11 and is in contact with or free of play with rod 12 roughly opposite the area of contact between this rod and the tip 23 of the pusher 13.

Le poussoir 14 n'intervient donc pas dans l'actionnement des goupilles 26 et 28.The pusher 14 therefore does not intervene in actuation of pins 26 and 28.

On remarque par ailleurs que la tige 12 formant organe de positionnement disposée dans le rotor 17 de façon à être engagée dans l'encoche 11 de la clé de façon dissymétrique, et se trouve rapprochée avec la surface latérale de l'encoche 11 définie par le côté intérieur de la branche 7 alors qu'elle est écartée de la surface intérieure de la branche 8 d'une distance égale ou supérieure à la course utile du poussoir pour actionner les goupilles 26 et 28 et les placer en position de déblocage en rotation du rotor 17 par rapport au stator 16.We also note that the rod 12 forming positioning member disposed in the rotor 17 of so as to be engaged in the notch 11 of the key so asymmetrical, and is close to the surface side of the notch 11 defined by the inner side of the branch 7 while it is moved away from the interior surface of branch 8 by an equal or greater distance at the useful stroke of the pusher to actuate the pins 26 and 28 and place them in the unlocking position in rotation of the rotor 17 relative to the stator 16.

Grâce à cet agencement, la clé suivant l'invention est réversible et peut donc être introduite indifféremment, de manière à faire intervenir le poussoir 13 ou le poussoir 14.Thanks to this arrangement, the key according to the invention is reversible and can therefore be introduced interchangeably, so as to involve the pusher 13 or pusher 14.

On voit également sur les figures 2 et 4 que les trous 31 de réception des poussoirs 13 et 14 sont disposés perpendiculairement à l'axe longitudinal de la clé, mais décalés selon l'épaisseur du corps de clé de manière à pouvoir être ménagés dans la partie pleine du corps 1 située à l'intérieur des profils définis par les rainures 2 et les nervures 3 sur les grandes faces latérales du corps 1. Ce décalage est ajustable afin d'optimiser le rainurage de la clé. We also see in Figures 2 and 4 that the holes 31 for receiving the pushers 13 and 14 are arranged perpendicular to the longitudinal axis of the key, but offset according to the thickness of the key body so as to can be housed in the full part of the body 1 located inside the profiles defined by the grooves 2 and the ribs 3 on the large lateral faces of the body 1. This offset is adjustable to optimize the grooving the key.

Un tel décalage permet de ne pas accroítre l'épaisseur du corps de clé.Such a shift does not increase the thickness of the key body.

On peut cependant également envisager de disposer les logements 31 pour les poussoirs 13 et 14 de façon coaxiale.However, we can also consider having the housings 31 for the pushers 13 and 14 so coaxial.

La clé suivant l'invention est dépourvue de rainurages latéraux, et de décrochements spéciaux en bout de clé, ce qui permet d'utiliser éventuellement ses chants pour réaliser sur toute la surface de ceux-ci des profils d'actionnement des goupilles du barillet.The key according to the invention is devoid of lateral grooves, and special recesses at the end of key, which allows the possible use of its edges to realize profiles on the whole surface actuating the pins of the barrel.

Du fait que les deux poussoirs sont montés chacun dans une branche d'une fourche, ils peuvent s'escamoter dans l'encoche 11 de la fourche et ne pas déborder de l'encombrement extérieur de la clé.Because the two pushers are mounted each in a branch of a fork, they can retract in the notch 11 of the fork and do not overflow the external dimensions of the key.

Comme le montre la figure 3, les axes des poussoirs 13 et 14 et par conséquent celui de la tige 12 montée dans le rotor 17 sont décalés par rapport à l'axe de la goupille 26 vers l'extrémité de la clé, intérieure au barillet et vers l'extrémité intérieure de son logement 18, de manière que lors du retrait de la clé, dès que les poussoirs quittent le contact avec la tige 12 formant organe de positionnement, le poussoir en contact avec la goupille 26, en l'occurrence le poussoir 13, soit repoussé vers l'intérieur de son logement 31 ménagé dans la branche 7 de la fourche, sous l'effet du ressort 30 de rappel de la goupille 28 en position de blocage.As shown in Figure 3, the axes of the pushers 13 and 14 and consequently that of the rod 12 mounted in rotor 17 are offset from the axis from pin 26 towards the end of the key, inside to the barrel and towards the inner end of its housing 18, so that when the key is removed, as soon as the pushers leave contact with rod 12 forming positioning member, the pusher in contact with the pin 26, in this case pusher 13, is pushed back towards the interior of its housing 31 formed in the branch 7 of the fork, under the effect of the return spring 30 of the pin 28 in the locked position.

Le fait de loger les pistons 13 et 14 dans les branches d'une fourche ménagée à l'extrémité de la clé, permet de réaliser avec un même corps de clé, une clé avec poussoir, une clé avec une encoche mais sans poussoir, et éventuellement une clé sans poussoir ni encoche, le contour extérieur de la clé étant toujours le même.The fact of housing the pistons 13 and 14 in the branches of a fork at the end of the key, allows to realize with the same key body, a key with push-button, a key with a notch but without push-button, and possibly a key without push button or notch, the outside outline of the key is always the same.

La clé suivant l'invention présente une forme générale simple et n'exige qu'un aménagement également très simple du rotor pour placer dans celui-ci une tige formant organe de positionnement, transversale à l'encoche ménagée à l'extrémité de la clé.The key according to the invention has a shape general simple and requires only a layout also very simple rotor to place a rod in it forming positioning member, transverse to the notch at the end of the key.

Key for operating a cylinder lock, the body (1) of the key of elongated form designed to enter a keyhole (18) in a barrel (17) of the lock being provided with operating means designed to co-operate with a displacing member (12) to shift at least one movable pin (26, 28) in the barrel (17) into a position allowing rotation of the barrel (17) of the lock with respect to the stationary part (16) of it, the shifting means for the pin being constituted by at least two thrust members (13, 14) mounted to be displaceable in translation, each in a hole (31) opening on the one hand into a passage for the displacing member (12) provided within the key and on the other hand into the lateral external surface of the corresponding limb (7, 8) of the said fork, characterised in that the holes (31) for the thrust members (13, 14) are provided in at least two limbs (7, 8) of a fork (6) at the end of the key, the gap (11) between the limbs (7, 8) of the fork being designed to receive the displacing member (12) on engagement of the key into the barrel (17) of the lock so as to cause displacement of the said pin (26, 28) by one of the thrust members (13, 14).
  2. Key according to claim 1, characterised in that the holes (31) which receive the thrust members (13, 14) are arranged perpendicular to the longitudinal axis of the key but offset depending on the thickness of the body of the key.
  3. Key according to either one of claims 1 and 2, characterised in that each thrust member (13, 14) has an end portion (22) facing towards the gap (11) between the limbs (7, 8) of the fork (6) and which terminates in a chamfered point (23) designed to co-operate with the displacing member (12) to cause displacement of the thrust member (13, 14) towards the outside of the profile of the key, and at the opposite end to the chamfered point (23) an end portion (25) designed to co-operate with the said pin (26) in the barrel (17) as well as a thicker portion (24) present between the said end portions (22, 25) and co-operating with abutment means (32, 34) which limit the displacement of the thrust member (13, 14) within its hole (31).
  4. Cylinder lock designed to be operated by a key according to any one of claims 1 to 3, comprising a stationary part (16) in which a barrel (17) is mounted to be displaceable in rotation under the action of the key, the said barrel including a displacing member (12) for a thrust member acting on at least one movable pin (26, 28) preventing rotation of the barrel, to displace it into a position allowing rotation of the barrel (17) with respect to the stationary part (16), characterised in that the said displacing member (12) is a spindle mounted in the barrel (17) and extending transverse to the keyhole (18), the said spindle being designed to be engaged in the gap (11) between the limbs (7, 8) of the fork at the end of the key on its insertion in the keyhole in the barrel (17) to cause displacement of the said pin (26, 28) by one of the thrust members (13, 14) mounted in the limbs (7, 8) of the said fork at the end of the key.
  5. Cylinder lock according to claim 4, characterised in that the said spindle (12) is arranged in the barrel (17) in such as way as to be engaged in the gap (11) between the limbs (7, 8) of the fork of the key in an asymmetrical manner and to be present close to that lateral surface of the gap defined by the inside wall of the limb (7) in which is mounted the thrust member (13) actuated by the spindle (12) and to be spaced away from the inside surface of the limb (8) in which the other thrust member (14) is mounted, through a distance equal to or greater than the useful travel of the thrust member actuated by the spindle to shift the said pin (26, 28) and put it in a position to release the barrel (17) for rotation with respect to the stationary part (16).
  6. Cylinder lock according to one of claims 4 and 5, characterised in that the spindle (12) is arranged in the barrel (17) with respect to the said pin(26, 28) of the barrel (17) with an axial offset towards the inner end of the keyhole (18) with the aim of allowing, during the withdrawal of the key, and when the thrust members (13, 14) cease contact with the spindle (12), the thrust member (13 or 14) to be pushed back towards the interior of its hole (31), provided in the limb (7 or 8) of the fork (6) of the key by engagement by the pin (24, 28) acted on by an elastic member (30) serving to restore the pin (26, 28) to the locking position.
