Abstract
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 all types, 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, in particular by destroying 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.
On connaît cependant par GB-A-907 523 correspondant au préambule de la revendication 1 un dispositif de condamnation de pênes d'une serrure comportant un ensemble d'au moins deux pênes destinés à être situés sur au moins un même chant d'un vantail, un moyen de verrouillage de ces pênes en position sortie, et un élément de maintien commandant l'amenée du moyen de verrouillage en position de condamnation en cas de tentative d'ouverture non autorisée de la serrure.GB-A-907 523, corresponding to the preamble of
Cependant, un tel dispositif ne permet pas de condamner en position de condamnation chacun de ces pênes individuellement.However, such a device does not allow each of these bolts to be locked in the locked position.
Conformément à l'invention, le moyen de verrouillage est une plaque de condamnation de l'ensemble de pênes ci-dessus, la plaque coulissant sur un même chant du boîtier de la serrure et étant traversée par les pênes de cet ensemble de pênes de manière à pouvoir condamner en position de condamnation chacun de ces pênes individuellement.According to the invention, the locking means is a plate for locking the set of bolts above, the plate sliding on the same edge of the lock housing and being crossed by the bolts of this set of bolts to be able to condemn each of these bolts individually in the condemnation position.
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.
Des formes de réalisation de l'objet de l'invention sont représentées, à titre d'exemples non limitatifs, au dessin annexé.Embodiments of the subject of the invention are shown, by way of nonlimiting examples, in the accompanying drawing.
La fig. 1 représente schématiquement une porte équipée du dispositif selon l'invention.Fig. 1 schematically represents a door equipped with the device according to the invention.
Les fig. 2a et 2b représentent deux formes de réalisation du dispositif de condamnation d'ouverture conforme à l'invention.Figs. 2a and 2b show two embodiments of the opening locking device according to the invention.

La fig. 7 est une vue semblable à la fig. 3 et montre la plaque de condamnation en position condamnée ou de condamnation du pêne.Fig. 7 is a view similar to FIG. 3 and shows the locking plate in the locked position or the latching position.
La fig. 8 est une vue de dessus de la fig. 7.Fig. 8 is a top view of FIG. 7.
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
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.
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
Comme on le voit au dessin, on peut prévoir une plaque de condamnation 4 unique pour les différents pênes 3 correspondant à chaque chant d'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
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
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
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
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
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
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
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.The
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
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 is now necessary to provide that, if the
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
Au contraire, lorsque sous l'influence d'une rupture du câble 23, 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 38 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
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
