Description

La présente invention est relative à un dispositif de contrôle d'accès à un espace fermé par une porte, tel qu'un habitacle de véhicule automobile par exemple, et, plus particulièrement à un tel dispositif comprenant des moyens électroniques pour interroger un circuit émetteur-récepteur porté par une personne désirant ouvrir ladite porte, pour reconnaítre un code prédéterminé émis en réponse par ledit circuit et pour commander alors le retrait d'un pion de verrouillage hors d'une encoche d'un pêne formant partie de la serrure de la porte, et des moyens d'activation par ladite personne desdits moyens électroniques.The present invention relates to a device for access control to a space closed by a door, such as a passenger compartment of a motor vehicle for example, and, more particularly to such a device comprising means electronics for interrogating a transceiver circuit worn by a person wishing to open said door, to recognize a predetermined code issued in response by said circuit and to order then the withdrawal of a pawn from locking out of a notch of a bolt forming part of the door lock, and activation means by said person of said electronic means.

On a représenté schématiquement à la figure 1 du dessin annexé un dispositif connu, par exemple du document EP 0218 251, de contrôle d'accès à un véhicule automobile, qui procède par reconnaissance d'un code émis par un badge 1 porté par une personne souhaitant entrer dans le véhicule. Le badge 1 comporte un circuit électronique pour émettre ce code mais cette émission n'est pas permanente, pour économiser la pile électrique alimentant le circuit. Le circuit est activé sur réception d'un signal émis par l'antenne 2 de moyens électroniques 3 comprenant un calculateur, placés dans le véhicule et susceptibles de reconnaítre le code émis en retour par le badge 1, de manière à autoriser ou interdire l'accès du véhicule à la personne en cause. Ces moyens électroniques 3 sont eux-mêmes activés par cette personne, par pression sur un bouton interrupteur 4 placé sur la porte 5 du véhicule, au voisinage d'une poignée telle qu'une palette 6 d'ouverture de cette porte, articulée en 61 sur celle-ci.There is shown schematically in Figure 1 of the accompanying drawing a known device, for example from document EP 0218 251, for controlling access to a motor vehicle, which proceeds by recognition of a code issued by a badge 1 worn by a person wishing to enter the vehicle. The badge 1 includes an electronic circuit for transmitting this code, but this transmission is not permanent, in order to save the electric battery supplying the circuit. The circuit is activated on reception of a signal sent by the antenna 2 of electronic means 3 comprising a computer, placed in the vehicle and capable of recognizing the code sent back by the badge 1, so as to authorize or prohibit the vehicle access to the person concerned. These electronic means 3 are themselves activated by this person, by pressing a switch button 4 placed on the door 5 of the vehicle, in the vicinity of a handle such as a pallet 6 for opening this door, articulated at 6 1 on it.

Ce bouton présente l'inconvénient d'être visible et on peut donc songer à le dissimuler dans la carrosserie, son actionnement étant alors commandé par la palette 6 comme proposé dans le document EP 0218 251 précité. Celle-ci permet, à l'aide d'une tringlerie 7 représentée de manière très schématique à la figure, de retirer un pêne 8 d'une gâche 9 pour permettre l'ouverture de la porte 5, pour autant qu'un pion 10 de blocage du pêne 8 soit dégagé d'une encoche 11 formée dans ce pêne. Ce sont évidemment les moyens électroniques 3 qui commandent ce dégagement, à l'aide d'un électroaimant 12 par exemple, lorsque le code émis par le badge est tel que la personne qui porte ce badge est autorisée à pénétrer dans le véhicule.This button has the disadvantage of being visible and can therefore think of hiding it in the body, its actuation then being controlled by pallet 6 as proposed in the aforementioned document EP 0218 251. This one allows, using a linkage 7 shown so very schematic in the figure, to remove a bolt 8 from a keeper 9 to allow the door 5 to open, to as long as a pin 10 for locking the bolt 8 is released from a notch 11 formed in this bolt. These are obviously the electronic means 3 which control this release, to using an electromagnet 12 for example, when the code issued by the badge is such that the person wearing this badge is allowed to enter the vehicle.

Lorsqu'on prévoit de coupler mécaniquement l'actionnement de l'interrupteur 4 à celui de la palette 6 d'ouverture de porte, on se heurte à la difficulté suivante. Une traction sur la palette 6 exercée par une personne qui veut accéder au véhicule a pour effet de mettre en butée le pion 10 contre un flanc de l'encoche 11, en établissant un frottement substantiel entre ces deux pièces. Si alors les moyens 3, ayant reconnu et accepté le code émis par le badge 1, excitent l'électroaimant 12 pour dégager le pion 10 du pêne 8 et permettre ainsi l'ouverture de la porte 5, ce frottement peut empêcher le dégagement du pion et la porte reste alors fermée. Pour surmonter cet incident, la personne peut alors relâcher sa traction sur la palette 6 de manière à réduire le frottement pêne/pion et permettre le dégagement de ces derniers. Cette manoeuvre supplémentaire constitue cependant une gêne qu'il est souhaitable d'éliminer.When planning to mechanically couple actuation from the switch 4 to that of the opening pallet 6 of door, we come up against the following difficulty. A traction on the pallet 6 exerted by a person who wants accessing the vehicle has the effect of abutting the counter 10 against a flank of the notch 11, by establishing a substantial friction between these two parts. If then means 3, having recognized and accepted the code issued by the badge 1, energize the electromagnet 12 to release the pin 10 of the bolt 8 and thus allow the opening of the door 5, this friction can prevent the release of the pin and the door remains closed. To overcome this incident, the no one can then release their traction on the pallet 6 so as to reduce the latch / pin friction and allow the release of these. This additional maneuver however constitutes an annoyance that it is desirable eliminate.

La présente invention a précisément pour but de fournir un dispositif de contrôle d'accès, notamment à un véhicule automobile qui, tout en ne faisant pas appel à la présence d'un bouton interrupteur visible sur la carrosserie à proximité d'une poignée de porte, assure le dégagement du pion en cas de reconnaissance et d'acceptation du code émis par le badge, avant qu'une traction exercée manuellement sur la palette 6 ne puisse établir entre ce pion et le pêne de la serrure un frottement insurmontable par les moyens utilisés pour dégager le pion.The object of the present invention is precisely to provide an access control device, in particular to a motor vehicle which, while not using the presence of a visible switch button on the body near a door handle, ensures release of the counter in the event of recognition and acceptance of the code issued by the badge, before a traction exerted manually on the pallet 6 cannot establish between this pawn and the bolt of the lock a insurmountable friction by the means used to release the pawn.

On atteint ce but de l'invention, ainsi que d'autres qui apparaítront à la lecture de la description qui va suivre, avec un dispositif du type décrit en préambule de la présente description, remarquable en ce que les moyens d'activation des moyens électroniques sont conçus pour permettre l'exécution d'un dialogue entre lesdits moyens électroniques et le circuit porté par la personne, ainsi que le déverrouillage éventuel du pêne de la serrure avant que l'action exercée par ladite personne sur ladite poignée ne provoque un blocage par frottement du pion dans ladite encoche du pêne de la serrure.This object of the invention is achieved, as well as other which will appear on reading the description which will follow, with a device of the type described in the preamble to the present description, remarkable in that the means activating electronic means are designed to allow the execution of a dialogue between said means electronic and the circuit worn by the person, as well that the possible unlocking of the bolt of the front lock that the action exerted by said person on said handle does not cause friction blocking of the pin in said notch of the bolt of the lock.

D'autres caractéristiques et avantages de la présente invention apparaítront à la lecture de la description qui va suivre et à l'examen du dessin annexé dans lequel :

  • la figure 1 est une représentation schématique d'un dispositif de contrôle d'accès de la technique antérieure décrit en préambule de la présente description, du type perfectionné par la présente invention, et
  • la figure 2 est une représentation schématique d'un mode de réalisation des moyens d'activation incorporés au dispositif suivant l'invention, ces moyens étant conçus pour se substituer au bouton interrupteur 4 du dispositif de la figure 1.
Other characteristics and advantages of the present invention will appear on reading the description which follows and on examining the appended drawing in which:
  • FIG. 1 is a schematic representation of an access control device of the prior art described in the preamble to the present description, of the type improved by the present invention, and
  • FIG. 2 is a schematic representation of an embodiment of the activation means incorporated in the device according to the invention, these means being designed to replace the switch button 4 of the device in FIG. 1.

Suivant la présente invention donc, on remplace le bouton interrupteur 4 du dispositif de la figure 1, par des moyens d'activation qui, dans l'exemple de réalisation schématiquement représenté à la figure 2, prennent la forme d'une barrette 13 d'interrupteurs 14i connectés électriquement en parallèle entre deux conducteurs 151, 152. Avantageusement, ces interrupteurs sont du type de ceux incorporés aux claviers dits "souples" de calculettes ou autres machines informatiques. On sait que ces interrupteurs sont alors formés par des pistes d'encre conductrice sérigraphiées sur deux feuilles de support souples en regard, suivant le dessin représenté à la figure 2, par exemple, la fermeture d'un interrupteur s'opérant par mise en pression locale des deux feuilles, à l'aide d'un doigt.According to the present invention therefore, the switch button 4 of the device in FIG. 1 is replaced by activation means which, in the embodiment schematically represented in FIG. 2, take the form of a bar 13 of switches 14 i electrically connected in parallel between two conductors 15 1 , 15 2 . Advantageously, these switches are of the type of those incorporated in so-called "flexible" keyboards of calculators or other computer machines. We know that these switches are then formed by conductive ink tracks screen printed on two flexible support sheets opposite, according to the drawing shown in Figure 2, for example, the closing of a switch operated by pressurization local of the two leaves, using a finger.

Suivant l'invention, on dispose la barrette 13 sur la face interne 16 de la palette 6 de poignée de porte (voir figure 1) et on raccorde les conducteurs ou pistes 151 et 152 aux moyens électroniques 3, en lieu et place des conducteurs 41, 42 associés au bouton interrupteur 4 du dispositif de la figure 1.According to the invention, the bar 13 is placed on the internal face 16 of the pallet 6 of the door handle (see FIG. 1) and the conductors or tracks 15 1 and 15 2 are connected to the electronic means 3, in place of the conductors 4 1 , 4 2 associated with the switch button 4 of the device in FIG. 1.

Dans cette position, la barrette 13 reste invisible de l'extérieur du véhicule, conformément à l'un des objectifs de l'invention. La présence d'une pluralité d'interrupteurs 14i, alignés horizontalement par exemple, assure qu'au moins un des interrupteurs se ferme lors de la prise en main de la palette 6, quelle que soit alors les positions des doigts de la main sur la barrette. Enfin et surtout, la fermeture quasi instantanée, sous une pression très légère, d'un des interrupteurs de la barrette 13 du type clavier souple, assure l'exécution complète du dialogue entre le calculateur 3 et le badge 1, qui prélude au dégagement du pion 10 quand le code émis par le badge est reconnu par le calculateur 3, avant que la traction exercée par la main sur la palette 6 n'ait entraíné le pêne 8 en butée contre le pion 10 (dans un délai de 100 ms environ) et établi entre ce pêne et ce pion un frottement tel que l'électroaimant 12 ne puisse dégager le pion du pêne.In this position, the bar 13 remains invisible from the outside of the vehicle, in accordance with one of the objectives of the invention. The presence of a plurality of switches 14 i , aligned horizontally for example, ensures that at least one of the switches closes when the pallet 6 is taken in hand, regardless of the positions of the fingers of the hand on the bar. Finally and above all, the almost instantaneous closing, under very light pressure, of one of the switches of the bar 13 of the flexible keyboard type, ensures the complete execution of the dialogue between the computer 3 and the badge 1, which is a prelude to the release of the pin 10 when the code issued by the badge is recognized by the computer 3, before the traction exerted by the hand on the pallet 6 has brought the bolt 8 into abutment against the pin 10 (within approximately 100 ms) and established between this bolt and this pin a friction such that the electromagnet 12 cannot disengage the pin from the bolt.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté qui n'a été donné qu'à titre d'exemple. C'est ainsi que les interrupteurs de la barrette de la figure 2 pourraient être remplacés par d'autres moyens susceptibles de lancer aussi rapidement le dialogue calculateur/badge, tel que des interrupteurs à effet capacitif, ou un détecteur de rayonnement infrarouge, etc., etc.,. On pourrait aussi établir un retard suffisant de l'établissement d'un frottement pion/pêne sur l'instant de dégagement du pêne, par des moyens purement mécaniques, tels qu'un ressort raidissant la manoeuvre de la palette de manière à ralentir son basculement, ou l'établissement d'une course morte initiale dans la tringlerie reliant la palette au pêne 8.Of course, the invention is not limited to the mode of realization described and represented which was given only as an example. This is how the switches of the bar of Figure 2 could be replaced by other means that could launch the calculator / badge dialog, such as switches capacitive effect, or an infrared radiation detector, etc., etc.,. We could also establish a sufficient delay the establishment of a pawn / bolt friction on the instant bolt release, by purely mechanical means, such as a spring stiffening the operation of the pallet so as to slow down its tilting, or the establishment of an initial dead race in the linkage connecting the latch pallet 8.

Enfin, si l'invention est plus particulièrement destinée à équiper une porte de véhicule automobile, il est clair qu'elle est susceptible d'application partout où l'accès d'un espace doit être réservé à des personnes autorisées, locaux industriels ou commerciaux, banques, etc...Finally, if the invention is more particularly intended to equip a motor vehicle door, it is clear that it can be applied wherever access to a space must be reserved for people authorized, industrial or commercial premises, banks, etc ...
