Figures 5 and 6, views according to claim 1
au cours de deux phases successives d'ouverture de la porte. during two successive phases of opening the door.
On voit aux figures 1 et 2 une nouvelle garniture de serrure destinée à être fixée à l'intérieur d'une porte, à la place de l'habituelle plaque de propreté. Cette garniture est un boîtier constitué d'une platine 6 entourée de rebords 1 qui s'appliquent sur la porte, et qui est traversée par des piliers de fixation 7. La platine est percée en partie inférieure d'un orifice 15 d'accès au cylindre de la serrure. De façon connue également le boîtier reçoit une béquille 5 manoeuvrée par la poignée 25 et équipée d'une rondelle 8 disposant de deux ergots 16 limitant le débattement de la béquille de part et d'autre We see in Figures 1 and 2 a new lock trim intended to be fixed inside a door, instead of the usual cleanliness plate. This lining is a housing consisting of a plate 6 surrounded by flanges 1 which are applied to the door, and which is crossed by fixing pillars 7. The plate is pierced in the lower part with an orifice 15 for access to the lock cylinder. In a known manner also the housing receives a crutch 5 maneuvered by the handle 25 and equipped with a washer 8 having two lugs 16 limiting the movement of the crutch on either side
d'une butée fixe 17.a fixed stop 17.
A l'intérieur du boîtier, un tiroir coulissant 2, ayant la forme d'une plaque rectangulaire avec une échancrure 24 à sa partie supérieure, coiffe l'orifice 15 quand il est dans la position basse représentée à la figure 1. Le tiroir est automatiquement dans cette position grâce à son poids. Il se prolonge vers le haut par une antenne Inside the housing, a sliding drawer 2, having the shape of a rectangular plate with a notch 24 at its upper part, covers the orifice 15 when it is in the low position shown in FIG. 1. The drawer is automatically in this position thanks to its weight. It is extended upwards by an antenna
latérale de guidage 18 appliquée le long du rebord 1. lateral guide 18 applied along the rim 1.
L'antenne est profilée, sa face intérieure étant inclinée vers le haut de la garniture. Au-dessus du tiroir, un moyen de verrouillage est constitué d'une biellette de condamnation 3 pivotante sur un axe fixe 4 rapporté sur la platine 6. La biellette dispose sur un côté, d'un bec 19 coopérant avec le plan incliné de l'antenne 18. Du côté opposé, la biellette est pourvue d'une échancrure 20 d'accrochage de la tige mobile 21 d'un petit électroaimant 22 rapporté à l'intérieur du boîtier. Au niveau de la béquille 5 est placée une petite lame ressort 9 solidaire du boîtier, destinée au verrouillage du tiroir 2 par l'intermédiaire de son antenne de guidage. Enfin en partie supérieure de la garniture est installé un coffret électronique 10 de manoeuvre équipé d'un connecteur 11. La figure 3 montre le boîtier de commande 12 permettant d'agir sur le coffret 10 par l'intermédiaire d'un The antenna is profiled, its inner face being inclined upwards of the lining. Above the drawer, a locking means consists of a locking rod 3 pivoting on a fixed axis 4 attached to the plate 6. The rod has on one side, a spout 19 cooperating with the inclined plane of the 'antenna 18. On the opposite side, the link is provided with a notch 20 for hooking the movable rod 21 with a small electromagnet 22 attached to the inside of the housing. At the stand 5 is placed a small leaf spring 9 secured to the housing, for locking the drawer 2 through its guide antenna. Finally, in the upper part of the lining, an electronic control unit 10 equipped with a connector is installed. FIG. 3 shows the control unit 12 making it possible to act on the box 10 via
codeur 13 et son contacteur 14.encoder 13 and its contactor 14.
La figure 1 représente le boîtier du dispositif avec son tiroir 2 en position basse, c'est-à-dire que l'orifice 15 est occulté et qu'on ne peut introduire de FIG. 1 represents the housing of the device with its drawer 2 in the low position, that is to say that the orifice 15 is obscured and that it is not possible to introduce
corps étranger dans le cylindre.foreign body in the cylinder.
Lorsque l'utilisateur autorisé souhaite accéder au cylindre il applique le boîtier de commande 12 sur le connecteur 11 du coffret 10, auquel il transmet un signal codé. Ce signal, décodé par l'électronique de gestion logée dans le coffret, agit sur l'électroaimant 22 lequel provoque pendant quelques secondes la rétraction de la tige 21, et par conséquent le basculement de la biellette 3 comme le montre la figure 4. Ainsi le bec 19 de la biellette s'écarte de l'antenne 18 ce qui a pour effet de déverrouiller le When the authorized user wishes to access the cylinder, he applies the control unit 12 to the connector 11 of the box 10, to which he transmits a coded signal. This signal, decoded by the management electronics housed in the box, acts on the electromagnet 22 which causes for a few seconds the retraction of the rod 21, and consequently the tilting of the rod 3 as shown in Figure 4. Thus the spout 19 of the link moves away from the antenna 18 which has the effect of unlocking the
tiroir 2.drawer 2.
Celui-ci peut donc être manoeuvré manuellement de l'extérieur grâce à une fente 23 prévue à sa partie inférieure qui permet à l'utilisateur de le remonter en le faisant coulisser dans le boîtier, par exemple en utilisant la pointe de sa clef. Le tiroir atteint la position montrée aux figures 2 et 5, qui libère l'accès au cylindre de serrure. Le tiroir est en butée contre l'axe 4 par son échancrure 24. Son antenne latérale 18 s'est engagée entre la lame ressort 9 et le rebord 1, ce qui permet le maintien du tiroir en position haute. L'utilisateur peut donc ouvrir It can therefore be manually operated from the outside thanks to a slot 23 provided at its lower part which allows the user to wind it up by sliding it in the housing, for example by using the tip of its key. The drawer reaches the position shown in Figures 2 and 5, which frees access to the lock cylinder. The drawer is in abutment against the axis 4 by its notch 24. Its lateral antenna 18 is engaged between the leaf spring 9 and the flange 1, which allows the drawer to be held in the high position. The user can therefore open
la serrure, puis retirer sa clef.the lock, then remove the key.
Lors de la manoeuvre de la béquille 5 à l'aide de la poignée 25 pour l'ouverture de la porte (figure 6), lorsqu'un ergot 16 de la rondelle 8 vient en appui contre la butée 17, l'autre ergot a repoussé l'antenne 18 et le tiroir 2, ainsi libéré de la lame ressort 9, retombe grâce à son propre poids. L'électroaimant 22 ayant atteint la limite de sa temporisation revient au repos, et par l'intermédiaire de la biellette 3, il bloque le tiroir 2 en position basse During the operation of the stand 5 using the handle 25 for the opening of the door (Figure 6), when a lug 16 of the washer 8 comes to bear against the stop 17, the other lug has pushed back the antenna 18 and the drawer 2, thus freed from the leaf spring 9, falls thanks to its own weight. The electromagnet 22 having reached the limit of its time delay returns to rest, and by means of the link 3, it blocks the slide 2 in the low position
cachant ainsi l'accès au cylindre.thus hiding access to the cylinder.
Il faudra une autre impulsion du boîtier de It will take another pulse from the
commande 12 pour libérer le tiroir et recommencer le cycle. command 12 to release the drawer and start the cycle again.
Afin d'augmenter le niveau de sécurité de la condamnation du tiroir, l'électronique de gestion peut être équipée de tous types de lecteurs, badges, cartes à puce, transpondeurs In order to increase the security level of the locking of the drawer, the management electronics can be equipped with all types of readers, badges, smart cards, transponders
etc... et les différents identifiants correspondants. etc ... and the different corresponding identifiers.
Enfin, pour compenser les différences d'affleurement des cylindres, le protège cylindre sera Finally, to compensate for differences in cylinder outcrop, the cylinder guard will

Le système décrit est simple et peu onéreux puisqu'il est autonome, sans câblage extérieur ni alimentation interne à la béquille. Il peut remplacer toute plaque de propreté standard, du côté extérieur au local, sans possibilité de démontage. Le boîtier de commande indépendant, du type porte-clefs simplifie l'alimentation et The system described is simple and inexpensive since it is autonomous, without external wiring or internal power supply to the stand. It can replace any standard cleanliness plate, from the outside to the room, without the possibility of disassembly. The independent control box, of the key ring type, simplifies power supply and
