Description

La présente invention concerne les dispositifs électromécaniques de manoeuvre commandés par un code tels qu'un verrou électrique, à un moteur d'ouverture d'une porte...; l'invention s'applique à tous les dispositifs dont l'accès est commandé par la composition d'un code connu des seules personnes autorisées et elle peut en particulier s'appliquer à des dispositifs d'accès à un compte bancaire tels que des distributeurs.The present invention relates to electromechanical operating devices controlled by a code such as an electric lock, to a door opening motor ...; the invention applies to all devices whose access is controlled by the composition of a code known only to authorized persons and it can in particular be applied to devices for accessing a bank account such as ATMs .

Ces dispositifs comportent généralement une unité de commande disposée au voisinage de l'appareil dont l'accès est contrôlé et qui comprend un interface d'entrée de code comportant un clavier ou analogue, ledit interface étant relié à un comparateur qui reçoit par ailleurs le code d'actionnement enregistré sous forme électronique dans une mémoire; le comparateur commande un dispositif électrique d'actionnement lorsque le code entrée par l'utilisateur sur le clavier est le même que le code d'actionnement enregistré dans la mémoire.These devices generally include a control unit arranged in the vicinity of the device, the access of which is controlled and which comprises a code entry interface comprising a keyboard or the like, said interface being connected to a comparator which also receives the code. actuation recorded in electronic form in a memory; the comparator controls an electrical actuation device when the code entered by the user on the keyboard is the same as the actuation code recorded in the memory.

On prévoit également une unité de surveillance située à distance de l'appareil contrôlé et qui effectue le contrôle et/ou la commande de la porte.There is also a monitoring unit located at a distance from the controlled device and which performs the control and / or command of the door.

Ces dispositifs engendrent généralement des alarmes émises par exemple lors d'une tentative de sabotage de la porte ou lors de tentatives d'ouverture avec des faux codes. Cependant lorsqu'un utilisateur autorisé compose avec le code correct sous la menace ou la contrainte, il n'est pas possible d'avertir l'unité de surveillance puisqu'il n'y a pas de manipulation interdite de la serrure.These devices generally generate alarms emitted, for example, when an attempt is made to sabotage the door or when attempts to open with false codes are made. However, when an authorized user dials with the correct code under threat or coercion, it is not possible to warn the monitoring unit since there is no prohibited manipulation of the lock.

La présente invention a pour objet un dispositif électromécanique de manoeuvre du type précité dans laquelle il est possible à un utilisateur de faire savoir à l'unité de surveillance qu'il a composé le code sous la contrainte.The present invention relates to an electromechanical operating device of the aforementioned type in which it is possible for a user to let the monitoring unit know that he has composed the code under duress.

On connaît déjà, du document US-A-3 878 511, un dispositif complexe destiné à contrôler l'accès d'une banque. La solution décrite consiste à prévoir une version modifiée du code d'accès normal pour l'ouverture sous contrainte. En d'autres termes l'utilisateur doit se rappeler de deux codes à huit chiffres pour l'ouverture normale de la porte puis de deux autres codes de huit chiffres légèrement modifiés pour l'ouverture sous contrainte.Already known from document US-A-3 878 511, a complex device intended to control access to a bank. The solution described consists in providing a modified version of the normal access code for opening under duress. In other words, the user must remember two eight-digit codes for normal door opening and then two other slightly changed eight-digit codes for forced opening.

Il est connu également du document LOCKSMITH LEDGER Vol 39, n° 6, mai 1979 d'indiquer la contrainte par l'action d'un bouton de contrainte en plus du code d'accès. Mais le fait d'actionner un bouton spécial en plus du clavier d'entrée risque fortement d'attirer l'attention de la personne qui menace.It is also known from the document LOCKSMITH LEDGER Vol 39, n ° 6, May 1979 to indicate the constraint by the action of a constraint button in addition to the access code. But pressing a special button in addition to the input keyboard is very likely to attract the attention of the person threatening.

Le dispositif selon l'invention est notamment remarquable en ce que l'unité de commande comporte un circuit sensible à l'actionnement d'au moins un élément de code prédéterminé et activé pendant une période prédéterminée suivant la détection du code correct par le comparateur de manière à engendrer une alarme de codage sous contrainte qui est transmise à l'unité de surveillance.The device according to the invention is notably remarkable in that the control unit comprises a circuit sensitive to the actuation of at least one element of predetermined code and activated for a predetermined period following the detection of the correct code by the comparator of so as to generate a duress coding alarm which is transmitted to the monitoring unit.

De cette manière, il suffit que l'utilisateur après avoir composé le code correct compose ledit ou lesdits éléments code supplémentaires prédéterminés pendant ladite période prédéterminée pour que l'unité de commande émette un signal d'alarme de codage sous contrainte qui est transmis de manière discrète à l'unité de surveillance. Celle-ci est alors prévenue et peut prendre alors les mesures qui s'imposent.In this way, it suffices for the user after having composed the correct code to compose said predetermined additional code element or elements during said predetermined period for the control unit to emit a stress coding alarm signal which is transmitted in a manner discreet to the surveillance unit. The latter is then notified and can then take the necessary measures.

Selon un mode de réalisation de l'invention, l'unité de commande comporte une temporisation qui est activée par le comparateur lorsque le code frappé est correct, le signal temporisé étant envoyé sur un circuit logique ET recevant par ailleurs un signal significatif de la composition sur le clavier du ou des éléments de code prédéterminés supplémentaires.According to one embodiment of the invention, the control unit includes a timer which is activated by the comparator when the code entered is correct, the delayed signal being sent on a logic circuit AND also receiving a significant signal of the composition on the keyboard of the additional predetermined code element (s).

Avantageusement, l'unité de commande comporte une mémoire qui mémorise ledit signal d'alarme de codage sous contrainte, ladite mémoire étant remise à zéro par l'unité de surveillance.Advantageously, the control unit includes a memory which stores said constraint coding alarm signal, said memory being reset to zero by the monitoring unit.

La temporisation déterminant la période prédéterminée pendant laquelle l'utilisateur peut composer le ou les éléments de codes supplémentaires doit être relativement faible puisque l'utilisateur doit composer ce ou ces éléments de code de manière normale, à la même vitesse qu'il a composé les éléments du code correct. Cette temporisation peut par exemple être fixée à quelques secondes.The time delay determining the predetermined period during which the user can compose the additional code element or elements must be relatively short since the user must compose this or these code elements in a normal manner, at the same speed as he composed the elements of the correct code. This time delay can for example be set to a few seconds.

D'autres caractéristiques et avantages de l'invention ressortiront de la description qui suit d'un exemple de réalisation de l'invention appliquée à une serrure à gâche électrique ainsi que les dessins ci- annexés sur lesquels:

  • - La Figure 1 est un schéma synoptique d'une serrure à gâche électrique conforme à la présente invention et,
  • - la Figure 2 représente un mode de réalisation du circuit de détection d'entrée sous contrainte et du circuit de mémorisation du signal d'alarme d'entrée sous contrainte.
Other characteristics and advantages of the invention will emerge from the description which follows of an exemplary embodiment of the invention applied to an electric strike lock as well as the attached drawings in which:
  • FIG. 1 is a block diagram of an electric strike lock according to the present invention and,
  • - Figure 2 shows an embodiment of the input stress detection circuit and the storage circuit of the stress input alarm signal.

Sur la figure 1 on a représenté de manière très schématique une serrure à gâche électrique commandée par code composé sur un clavier 1 qui constitue avec un dispositif de codage 2 un interface d'entrée; le code obtenu est envoyé à un comparateur 3 qui reçoit par ailleurs un code préenregistré d'ouverture contenu dans une mémoire 4. En cas de coïncidence des deux codes, le code frappé sur le clavier 1 et le code d'ouverture enregistré dans la mémoire 4, le comparateur 3 agit sur un circuit 5 de commande d'ouverture qui envoie un signal d'ouverture à la gâche électrique 6.In Figure 1 is shown very schematically an electric strike lock controlled by code composed on a keyboard 1 which constitutes with an encoding device 2 an input interface; the code obtained is sent to a comparator 3 which also receives a prerecorded opening code contained in a memory 4. In the event of coincidence of the two codes, the code entered on the keyboard 1 and the opening code recorded in the memory 4, the comparator 3 acts on an opening control circuit 5 which sends an opening signal to the electric strike 6.

Conformément à l'invention, l'actionnement d'une ou plusieurs touches prédéterminées sur le clavier 1 après la frappe du code correct pendant une période déterminée succédant à l'émission du signal d'ouverture de la porte engendre un signal d'alarme d'entrée sous contrainte. Ceci est réalisé par un circuit logique ET 7 qui reçoit d'une part du clavier 1 un signal significatif de la frappe de la ou des touches supplémentaires précitées, et, d'autre part, un signal temporisé fourni par un circuit de temporisation 8 activé par le signal de commande d'ouverture de la gâche électrique 6. La sortie du circuit ET 7 constitue un signal d'alarme d'entrée sous contrainte qui est avantageusement mémorisé dans une mémoire 9 et envoyé de manière discrète à l'unité de surveillance par la ligne 11. Grâce à ce dispositif électronique, la frappe du ou des éléments de code supplémentaire n'entraîne le déclenchement d'une alarme que si elle suit la composition du code correct et cela pendant une durée limitée. Il en résulte en particulier que les éléments de code supplémentaires peuvent être des éléments utilisés dans le code d'ouverture.In accordance with the invention, the actuation of one or more predetermined keys on the keyboard 1 after the correct code has been entered for a determined period following the emission of the door opening signal generates an alarm signal d entry under duress. This is achieved by an AND logic circuit 7 which receives on the one hand from the keyboard 1 a significant signal from the striking of the above-mentioned additional key (s), and, on the other hand, a timed signal supplied by a timer circuit 8 activated by the electric strike opening control signal 6. The output of the AND circuit 7 constitutes an input stress alarm signal which is advantageously stored in a memory 9 and sent discreetly to the monitoring unit by line 11. Thanks to this electronic device, the typing of the additional code element (s) will only trigger an alarm if it follows the correct code and for a limited time. As a result, in particular, the additional code elements may be elements used in the opening code.

La temporisation du circuit de temporisation 8 est réglée à une valeur relativement faible, sa durée étant seulement suffisante pour que l'utilisateur puisse frapper les touches supplémentaires de manière normale afin de ne pas donner l'éveil à la personne qui le contraint à ouvrir la porte; cette temporisation peut être par exemple de l'ordre de quelques secondes.The timing of the timing circuit 8 is set to a relatively low value, its duration being only sufficient for the user to be able to strike the additional keys in a normal manner so as not to give arousal to the person who forces him to open the door; this time delay can for example be of the order of a few seconds.

La figure 2 représente un mode de réalisation des circuits 7 et 9 de la figure 1. La touche supplémentaire est constituée par un contact 12 qui met en court-circuit un condensateur 13 qui est alimenté par une tension positive par l'intermédiaire d'une résistance 14, l'autre borne du condensateur 13 étant reliée à la masse. Le circuit ET est en fait constitué par un circuit NON-OU 15; il reçoit d'une part la tension aux bornes du condensateur 13 et d'autre part un signal de temporisation fourni par le circuit de temporisation 8 et inversé par exemple au moyen d'une porte inverseuse 16. Etant donné que le signal fourni par le condensateur 13 est normalement au niveau haut et passe au niveau bas lorsqu'on actionne la touche 12, le circuit NON-OU 15 est équivalent au circuit ET 7 puisqu'il reçoit les compléments des informations reçues par le circuit ET de la figure 1.FIG. 2 represents an embodiment of the circuits 7 and 9 of FIG. 1. The additional key consists of a contact 12 which short-circuits a capacitor 13 which is supplied by a positive voltage via a resistor 14, the other terminal of the capacitor 13 being connected to ground. The AND circuit is in fact constituted by a NOR circuit 15; it receives on the one hand the voltage across the capacitor 13 and on the other hand a time delay signal supplied by the time delay circuit 8 and inverted for example by means of an inverting gate 16. Since the signal supplied by the capacitor 13 is normally at the high level and goes to the low level when the button 12 is pressed, the NOR circuit 15 is equivalent to the AND circuit 7 since it receives the additional information received by the AND circuit of FIG. 1.

Le circuit de mémorisation du signal d'entrée sous contrainte fourni par la porte NON-OU 15 est constitué de deux portes NON-OU en séries 17 et 18, la sortie de la deuxième porte étant reliée à une des entrées de la première; l'ensemble de ces deux portes est relié à la base d'un transistor 19 par une résistance 20. Ce transistor 19 est branché entre une source de tension positive par l'intermédiaire d'une résistance 21 et la masse et, il fournit sur son collecteur un signal d'alarme mémorisé qui est envoyé sur la ligne 11.The circuit for memorizing the input signal under stress supplied by the NOR gate 15 consists of two NOR gates in series 17 and 18, the output of the second gate being connected to one of the inputs of the first; the set of these two gates is connected to the base of a transistor 19 by a resistor 20. This transistor 19 is connected between a positive voltage source by means of a resistor 21 and the ground and, it provides on its collector a memorized alarm signal which is sent on line 11.

Si l'on actionne la touche 12 pendant la durée du signal de temporisation fourni par le circuit 8, la porte 15 bascule et son entrée passe au niveau haut ce qui fait commuter la porte 17 dont la sortie passe au niveau bas et cette porte est maintenue dans cet état par la porte 18. Le transistor 19 devient conducteur et on obtient alors que la ligne 11 un signal de niveau haut d'alarme d'entrée sous contrainte. Une ligne 22 provenant de l'unité de surveillance permet la suppression du signaè d'alarme en faisant basculer la porte 18 de mémorisation de ce signal.If the button 12 is pressed for the duration of the time delay signal supplied by the circuit 8, the door 15 switches and its input goes to high level which switches door 17 whose output goes to low level and this door is maintained in this state by the gate 18. The transistor 19 becomes conductive and one obtains then that the line 11 a signal of high level of alarm of entry under stress. A line 22 coming from the monitoring unit allows the suppression of the alarm signal by switching the door 18 for memorizing this signal.

La description ci-dessus d'un exemple de réalisation n'a été fournie qu'à titre illustratif et nullement limitatif et il est évident que l'on peut y apporter des modifications ou variantes sans pour autant sortir du cadre de la présente invention.The above description of an exemplary embodiment has been provided for illustration only and is in no way limitative and it is obvious that modifications or variants can be made without departing from the scope of the present invention.

En particulier, on peut remplacer les composants utilisés par d'autres composants remplissant la même fonction, par exemple les mémoires peuvent être remplacés par des circuits bloqueurs ou des bascules.In particular, the components used can be replaced by other components fulfilling the same function, for example the memories can be replaced by blocking circuits or flip-flops.

Par ailleurs, l'invention a été décrite en application à une serrure à gâche électrique, mais il est évident qu'elle s'applique à tous appareils ou dispositifs dont l'accès est commandé par un dispositif électromécanique de manoeuvre commandé par un code.Furthermore, the invention has been described in application to an electric strike lock, but it is obvious that it applies to all devices or devices whose access is controlled by an electromechanical operating device controlled by a code.
