Description

La présente invention concerne un dispositif de condamna­tion pour pêne de serrure qui est adaptable sur toutes les serrures, comportant au moins un pêne assurant la fermeture par exemple des portes fortes, portes blindées, coffres de tout type, meubles de sécurité, armoires fortes et serrures du bâtiment.The present invention relates to a locking device for a lock bolt which is adaptable to all locks, comprising at least one bolt ensuring the closing, for example of strong doors, armored doors, safes of any type, security furniture, strong cupboards and locks of the building.

On sait que l'habileté des perceurs de coffres forts et en général de tous systèmes blindés est pratiquement infinie et que peu de serrures résistent à une ouverture notamment par destruction du dispositif de blocage du pêne en position de verrouillage dans sa gâche, de sorte qu'il devient alors possible de tirer le pêne hors de la gâche pour permettre l'ouverture de la serrure et donc du système blindé.We know that the skill of piercers of safes and in general of all armored systems is practically infinite and that few locks resist opening especially by destruction of the bolt blocking device in the locked position in its strike, so that 'it then becomes possible to pull the bolt out of the striker to allow the opening of the lock and therefore of the armored system.

L'invention résout le problème ci-dessus d'une manière particulièrement appropriée en créant un dispositif peu encombrant de condamnation d'ouverture d'une serrure par verrouillage du pêne en position sortie dans le cas d'une tentative d'ouverture, que cette tentative d'ouverture ait notamment lieu par voie thermique ou par perçage.The invention solves the above problem in a particularly appropriate manner by creating a space-saving device for preventing the opening of a lock by locking the bolt in the extended position in the event of an opening attempt, that this attempt to open takes place in particular by thermal means or by drilling.

Conformément à l'invention, le dispositif de condamnation pour pêne de serrure comportant au moins un pêne, est caractérisé en ce qu'il comprend au moins une plaque de condamnation d'au moins un pêne en position sortie et un élément de maintien qui commande l'amenée en position de condamnation de la plaque de condamnation.According to the invention, the locking device for a lock bolt comprising at least one bolt, is characterized in that it comprises at least one locking plate for at least one bolt in the extended position and a holding element which controls bringing the locking plate into the locking position.

Selon une autre caractéristique de l'invention, on prévoit un système de blocage de la plaque de condamna­tion en position de condamnation du pêne.According to another characteristic of the invention, there is provided a system for blocking the locking plate in the locking position of the bolt.

Diverses autres caractéristiques de l'invention ressor­tent d'ailleurs de la description détaillée qui suit.Various other characteristics of the invention will also emerge from the detailed description which follows.

A la fig. 1, on a représenté de manière schématique la porte 1, pivotant selon 2, d'un système blindé tel que portes fortes, portes blindées, coffres de tout type, meubles de sécurité, armoires fortes, ou la porte d'un système équipé de serrures du bâtiment.In fig. 1, there is shown schematically the door 1, pivoting along 2, of an armored system such as strong doors, armored doors, safes of any type, security furniture, strong cupboards, or the door of a system fitted with building locks.

La porte 1 de la fig. 1 présente un certain nombre de pênes latéraux 3 représentés au dessin en position sortie dans la paroi encadrant la porte 1, les pênes inférieurs étant supposés rentrer directement dans le sol ou dans la partie inférieure du châssis de la porte.Door 1 in fig. 1 has a number of side bolts 3 shown in the drawing in the extended position in the wall framing the door 1, the lower bolts being assumed to enter directly into the ground or in the lower part of the door frame.

Conformément à l'invention et comme cela est montré en détail dans ce qui suit, une plaque de condamnation 4 peut coulisser dans une rainure correspondante du boîtier de la serrure et est traversée par les différents pênes, tandis qu'un système de blocage 5 permet de verrouiller la plaque de condamnation 4 lorsqu'une tentative d'effrac­tion aura amené la plaque 4 en position de condamnation des pênes 3.According to the invention and as shown in detail in the following, a locking plate 4 can slide in a corresponding groove in the lock housing and is crossed by the various bolts, while a locking system 5 allows to lock the locking plate 4 when an attempted break-in has brought the plate 4 into the locking position of the bolts 3.

Comme on le voit au dessin, on peut prévoir une plaque de condamnation 4 unique pour les différents pênes 3 corres­pondant à une serrure donnée. En outre, les divers systèmes de blocage 5 de la plaque de condamnation 4, qui peuvent être respectivement placés à des endroits varia­bles de cette plaque, sont de préférence protégés par un blindage 6. Dans le cas de la fig. 1 toutefois, la partie inférieure de la porte 1 ne comporte pas de blindage au niveau du système de blocage.As can be seen in the drawing, a single locking plate 4 can be provided for the different bolts 3 corresponding to a given lock. In addition, the various locking systems 5 of the locking plate 4, which can be respectively placed at variable locations on this plate, are preferably protected by a shield 6. In the case of FIG. 1, however, the lower part of door 1 does not have any shielding at the level of the blocking system.

Au dessin et notamment aux fig. 2a et 2b, on a représenté un pêne 3 monté sur une cornière de support 10, le pêne 3 comportant une partie de plus petit diamètre 3a (fig. 2a) ou simplement une gorge 3b (fig. 2b) délimitant, toutes deux, un épaulement 11.In the drawing and in particular in FIGS. 2a and 2b, there is shown a bolt 3 mounted on a support angle 10, the bolt 3 having a portion of smaller diameter 3a (fig. 2a) or simply a groove 3b (fig. 2b) delimiting, both shoulder 11.

Comme on le voit bien à la fig. 6 dans laquelle le pêne 3 est en position sortie, l'épaulement 11 du pêne 3 est situé à une distance de l'extrémité du pêne 3 telle que cet épaulement dépasse légèrement la surface extérieure de la plaque de condamnation 4 lorsque le pêne 3 est complètement sorti de la serrure, cette plaque de condam­nation 4 présentant évidemment un orifice approprié au passage du pêne 3 et étant montée sur une plaque de support fixe 12.As can be seen in FIG. 6 in which the bolt 3 is in the extended position, the shoulder 11 of the bolt 3 is located at a distance from the end of the bolt 3 such that this shoulder slightly protrudes from the outside surface of the locking plate 4 when the bolt 3 is completely out of the lock, this locking plate 4 obviously having an orifice suitable for the passage of the bolt 3 and being mounted on a fixed support plate 12.

Aux fig. 3 et 5, on a représenté la plaque de condamna­tion 4 présentant pour le passage du pêne 3 une ouverture circulaire 13 prolongée par une partie oblongue 13a (fig. 3) ou carrée 13b (fig. 5) ; la forme de ce prolongement correspond à celle de la partie de plus petit diamètre 3a (fig. 2a) ou de la gorge 3b (fig. 2b) du pêne 3, la longueur de cette gorge 3b étant en outre au moins égale à l'épaisseur de la plaque de condamnation 4.In fig. 3 and 5, there is shown the locking plate 4 having for the passage of the bolt 3 a circular opening 13 extended by an oblong part 13a (fig. 3) or square 13b (fig. 5); the shape of this extension corresponds to that of the part of smaller diameter 3a (fig. 2a) or of the groove 3b (fig. 2b) of the bolt 3, the length of this groove 3b being also at least equal to the thickness of the locking plate 4.

Comme on l'a vu plus haut, la plaque de condamnation 4 est prévue pour pouvoir coulisser et la plaque de support présente à cet effet des pions de guidage 14 auxquels correspondent des lumières 15 prévues dans la plaque de condamnation 4.As seen above, the locking plate 4 is designed to be able to slide and the support plate has for this purpose guide pins 14 to which correspond the slots 15 provided in the locking plate 4.

De manière à commander le coulissement de la plaque de condamnation 4, on prévoit un ressort 20 dont une extré­mité est fixée en 21 à la plaque de support 12 et dont l'autre extrémité est fixée en 22 à la plaque de condam­nation 4. Un câble 23 est en outre relié en 24 à la plaque de condamnation 4 de manière telle qu'en position tendue du câble 23, celle-ci se trouve dans la position des fig. 3 ou 5 et laisse librement passer le pêne 3 à travers l'ouverture 13.In order to control the sliding of the locking plate 4, a spring 20 is provided, one end of which is fixed at 21 to the support plate 12 and the other end of which is fixed at 22 to the locking plate 4. A cable 23 is further connected at 24 to the locking plate 4 so that in the tensioned position of the cable 23, the latter is in the position of FIGS. 3 or 5 and lets the bolt 3 pass freely through the opening 13.

Au contraire, lorsqu'en position sortie du ou des pênes 3, le câble a été coupé comme indiqué ci-après, la plaque de condamnation 4 coulisse sous l'action du ressort 20 et occupe alors la position de la fig. 7, c'est-à-dire une position telle que l'épaulement 11 du pêne 3 vient en butée contre le prolongement 13a (ou 13b) de l'ouverture 13 et empêche le pêne de rentrer à l'intérieur de la serrure qui se trouve ainsi dans la position de condamna­tion du pêne en position sortie.On the contrary, when in the extended position of the bolt (s) 3, the cable has been cut as indicated below, the locking plate 4 slides under the action of the spring 20 and then occupies the position of FIG. 7, that is to say a position such that the shoulder 11 of the bolt 3 comes into stop against the extension 13a (or 13b) of the opening 13 and prevents the bolt from entering inside the lock which is thus in the position for locking the bolt in the extended position.

Conformément à l'invention, le câble 23 par un dispositif de renvoi à bobines 25, est placé sur la surface du système à protéger en suivant un trajet prédéterminé passant notamment par les points de passage obligatoires lors d'une attaque du système par un cambrioleur éven­tuel. En outre, le câble 23 est lui-même sensible par exemple à la chaleur (attaque du système par chalumeau) ou à la découpe (attaque du système par perçage). Des attaques du système à protéger ont donc pour conséquence une rupture du fil 23 et une manoeuvre correspondante de coulissement de la plaque de condamnation 4 comme indi­quée ci-dessus.According to the invention, the cable 23 by a reel return device 25, is placed on the surface of the system to be protected by following a predetermined path passing in particular through the compulsory passage points during an attack on the system by a burglar eventual. In addition, the cable 23 is itself sensitive for example to heat (attack of the system by torch) or to cutting (attack of the system by drilling). Attacks on the system to be protected therefore result in a break in the wire 23 and a corresponding sliding maneuver of the locking plate 4 as indicated above.

A la place du dispositif ci-dessus à ressort 20 et câble 23, on peut prévoir un dispositif électromécanique tel que, si le courant est coupé par une attaque quelconque du système à protéger, le dispositif déclenche la manoeu­vre de la plaque de condamnation 4, un fil électrique étant alors placé aux endroits sensibles du système blindé de la même façon que le câble 23. De même, la manoeuvre de la plaque de condamnation 4 peut être commandée par tout autre organe électromagnétique incor­porant un moyen électrique ou électronique, soit interne soit externe.In place of the above device with spring 20 and cable 23, an electromechanical device can be provided such that, if the current is interrupted by any attack by the system to be protected, the device triggers the operation of the locking plate 4, an electric wire then being placed in the sensitive places of the shielded system in the same way as the cable 23. Similarly, the operation of the locking plate 4 can be controlled by any other electromagnetic member incorporating an electrical or electronic means, either internal or external.

Il est également possible de commander la manoeuvre de la plaque de condamnation par un autre organe de type mécanique, et par exemple par une serrure ou un mécanisme commandé par une poignée et pouvant éventuellement lui-même être bloqué par une serrure. Dans de tels cas, le dispositif de condamnation selon l'invention n'est plus sensible à une attaque quelconque du système à protéger mais peut être commandé par une clé ou autre système de sûreté.It is also possible to control the operation of the locking plate by another mechanical type member, and for example by a lock or a mechanism controlled by a handle and which may itself be blocked by a lock. In such cases, the locking device according to the invention is no longer sensitive to any attack by the system to protect but can be controlled by a key or other security system.

Il y a maintenant lieu de prévoir que si la plaque 4 a coulissé en position de condamnation des pênes, il sera impossible de déplacer cette plaque pour la remettre dans la position de non-condamnation des fig. 3 et 5. Le système de blocage 5 indiqué précédemment répond à ce problème.It should now be provided that if the plate 4 has slid into the locking position of the bolts, it will be impossible to move this plate to return it to the non-locking position of FIGS. 3 and 5. The blocking system 5 indicated above responds to this problem.

Comme on le voit au dessin, le système de blocage 5 qui est fixé à la plaque de support 12 comprend un doigt 31 et un ressort de pression 32 prenant appui contre la vis 33 du boîtier du système de blocage 5. Ainsi, en position normale de fonctionnement de la serrure ou de non-­condamnation par la plaque 4, le doigt 31 vient en butée contre une partie pleine de la plaque de condamnation 4. Le système de blocage 5 est alors dans la position représentée en traits discontinus aux fig. 3 et 5.As seen in the drawing, the locking system 5 which is fixed to the support plate 12 comprises a finger 31 and a pressure spring 32 bearing against the screw 33 of the housing of the locking system 5. Thus, in the normal position operating the lock or non-locking by the plate 4, the finger 31 abuts against a solid part of the locking plate 4. The locking system 5 is then in the position shown in broken lines in Figs. 3 and 5.

Au contraire, lorsque sous l'influence d'une rupture du câble 25, par exemple, la plaque 4 est amenée dans la position de condamnation de la fig. 7, le doigt 31 est amené à pénétrer dans un orifice 33 prévu à cet effet dans la plaque de condamnation 4. La position correspon­dante du système de blocage 5 est alors montrée en traits fins continus à la fig. 7. La plaque de condamnation 4 ne peut donc plus bouger.On the contrary, when under the influence of a break in the cable 25, for example, the plate 4 is brought into the locking position of FIG. 7, the finger 31 is brought into a hole 33 provided for this purpose in the locking plate 4. The corresponding position of the locking system 5 is then shown in solid continuous lines in FIG. 7. The locking plate 4 can therefore no longer move.

On augmente encore la sécurité du dispositif en pré­voyant, comme à la fig. 1, une plaque de blindage parti­culière 6 au niveau du système de blocage 5. De même, le système de blocage 5 peut être prévu à un endroit quel­conque de la plaque de condamnation 4 de manière à se trouver à un endroit totalement indéterminé.The safety of the device is further increased by providing, as in FIG. 1, a particular shielding plate 6 at the level of the blocking system 5. Likewise, the blocking system 5 can be provided at any location on the locking plate 4 so as to be at a completely unspecified location.

L'invention n'est pas limitée aux exemples de réalisation représentés et décrits en détail, car diverses modifica­tions peuvent y être apportées sans sortir de son cadre. En particulier, on peut prévoir d'utiliser, pour le moyen de verrouillage du pêne en position sortie et à la place de la coopération de la plaque de condamnation 4 et de l'épaulement 11 du pêne 3, ou en liaison avec cette plaque, un système à tige prévu pour pénétrer dans un alésage latéral formé dans le pêne.The invention is not limited to the embodiments shown and described in detail, since various modifications can be made thereto without departing from its scope.
