A locking link (3) is actuated by a solenoid (22) to lock the slide. The solenoid is activated by an external control box (12).

Description

L'invention se rapporte à un dispositif de protection contre le vandalisme, du cylindre d'une serrure de porte.The invention relates to a device for protection against vandalism, of the cylinder of a lock door.

Pour empêcher l'accès au cylindre d'une serrure qui affleure à l'extérieur d'une porte, et éviter ainsi l'introduction par vandalisme de tout corps étranger dans l'orifice de la serrure, qui pourrait nuire à son bon fonctionnement, la Demanderesse a mis au point un dispositif de protection à l'aide d'un élément mobile qui occulte normalement le cylindre et qui est manoeuvré par un boítier de télécommande.To prevent access to the cylinder of a lock flush with the outside of a door, and thus avoid the introduction by vandalism of any foreign body into the hole in the lock, which could affect its good operation, the Applicant has developed a device protection using a mobile element that obscures normally the cylinder and which is operated by a housing remote control.

Le dispositif vient en applique sur une porte et s'adapte à une serrure et une semi-béquille existantes.The device is applied on a door and fits an existing lock and half handle.

L'invention a donc pour objet principal un dispositif de protection du cylindre d'une serrure de porte comportant un boítier s'appliquant à l'extérieur de la porte, boítier percé d'un orifice d'accès au cylindre de serrure et recevant une béquille manoeuvrée par une poignée, dispositif selon lequel un tiroir mobile est monté coulissant à l'intérieur du boítier, entre une position basse dans laquelle il occulte l'orifice d'accès au cylindre de serrure et une position haute dans laquelle il libère l'accès audit cylindre. Des moyens de verrouillage du tiroir mobile en position basse sont actionnés par un boítier de commande extérieur à la serrure.The main object of the invention is therefore a cylinder lock protection device for a door lock comprising a housing applying outside the door, housing pierced with a cylinder access hole lock and receiving a crutch operated by a handle, device in which a movable drawer is mounted sliding inside the case, between a position low in which it obscures the access hole to the cylinder lock and a high position in which it releases access to said cylinder. Drawer locking means movable in the low position are actuated by a box control outside the lock.

Pour le maintien du tiroir en position haute, le tiroir est pourvu d'une antenne latérale de guidage coopérant avec une lame ressort solidaire du boítier.To keep the drawer in the high position, the drawer has a lateral guide antenna cooperating with a leaf spring secured to the housing.

Selon une caractéristique particulière de l'invention, le moyen de verrouillage du tiroir mobile en position basse est constitué d'une biellette de condamnation pivotante sur un axe fixe sous l'action d'un électroaimant activé par le boítier de commande. Le boítier renferme en partie haute un coffret électronique, équipé d'un connecteur sensible au boítier de commande pour la manoeuvre de l'électroaimant.According to a particular characteristic of the invention, the locking means of the movable drawer in low position consists of a locking rod swivel on a fixed axis under the action of an electromagnet activated by the control box. The housing contains upper part of an electronic box, fitted with a connector sensitive to the control unit for the operation of the electromagnet.

D'autres caractéristiques et avantages de l'invention apparaítront à la lecture de la description suivante d'un exemple de réalisation, dans laquelle il sera fait référence aux dessins annexés qui représentent :

  • Figure 1, une vue en élévation de la face intérieure du boítier,
  • Figure 2, une vue en coupe verticale dudit boítier,
  • Figure 3, une vue schématique du boítier de commande,
  • Figure 4, une vue selon la revendication 1 montrant le déverrouillage du tiroir mobile en position basse.
  • Figures 5 et 6, des vues selon la revendication 1 au cours de deux phases successives d'ouverture de la porte.
  • Other characteristics and advantages of the invention will appear on reading the following description of an exemplary embodiment, in which reference will be made to the appended drawings which represent:
  • Figure 1, an elevational view of the inner face of the housing,
  • Figure 2, a vertical sectional view of said housing,
  • Figure 3, a schematic view of the control unit,
  • Figure 4, a view according to claim 1 showing the unlocking of the movable drawer in the low position.
  • Figures 5 and 6, views according to claim 1 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 boítier 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 boítier 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 d'une butée fixe 17.We see in Figures 1 and 2 a new packing lock intended to be fixed inside a door, instead of the usual cleanliness plate. This trim is a case consisting of a plate 6 surrounded of edges 1 which are applied to the door, and which is crossed by fixing pillars 7. The plate is pierced in the lower part of an orifice 15 for access to the lock cylinder. In a known manner also the housing receives a stand 5 maneuvered by the handle 25 and fitted with a washer 8 having two pins 16 limiting the travel of the stand on both sides a fixed stop 17.

    A l'intérieur du boítier, 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 latérale de guidage 18 appliquée le long du rebord 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 boítier.Inside the case, a sliding drawer 2, shaped like a rectangular plate with a notch 24 at its upper part, covers the orifice 15 when it is in the low position shown in the figure 1. The drawer is automatically in this position thanks to his weight. It is extended upwards by an antenna lateral guide 18 applied along the rim 1. The antenna is profiled, its inner face being inclined towards the top of the filling. Above the drawer, a way lock consists of a connecting rod locking 3 pivoting on a fixed axis 4 attached to the plate 6. The link has on one side a spout 19 cooperating with the inclined plane of the antenna 18. On the side opposite, the link is provided with a notch 20 for hooking the movable rod 21 of a small electromagnet 22 reported inside the housing.

    Au niveau de la béquille 5 est placée une petite lame ressort 9 solidaire du boítier, 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 boítier de commande 12 permettant d'agir sur le coffret 10 par l'intermédiaire d'un codeur 13 et son contacteur 14.At the stand 5 is placed a small leaf spring 9 secured to the housing, intended for locking of drawer 2 via its antenna guide. Finally in the upper part of the trim is installed an electronic control unit 10 equipped with a connector 11. Figure 3 shows the control box 12 allowing action on the box 10 via a encoder 13 and its contactor 14.

    La figure 1 représente le boítier 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 corps étranger dans le cylindre.Figure 1 shows the device housing with its drawer 2 in the low position, i.e. the orifice 15 is obscured and that one cannot introduce foreign body in the cylinder.

    Lorsque l'utilisateur autorisé souhaite accéder au cylindre il applique le boítier 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 tiroir 2.When the authorized user wishes to access to the cylinder he applies the control unit 12 to the connector 11 of box 10, to which it transmits a signal coded. 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 link 3 as the shows figure 4. Thus the spout 19 of the link moves away antenna 18 which has the effect of unlocking the 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 boítier, 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 la serrure, puis retirer sa clef.It can therefore be operated manually from the exterior thanks to a slot 23 provided in its part which allows the user to wind it up by sliding in the case, for example using the tip of his key. Drawer reaches the position shown Figures 2 and 5, which frees access to the cylinder lock. The drawer is in abutment against axis 4 by its notch 24. Its lateral antenna 18 is engaged between the leaf spring 9 and the rim 1, which allows the maintenance of the drawer in the high position. The user can therefore open 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 cachant ainsi l'accès au cylindre.When operating the stand 5 using the handle 25 for opening the door (FIG. 6), when a lug 16 of the washer 8 bears against the stop 17, the other lug pushed the antenna 18 and the drawer 2, thus freed from the leaf spring 9, falls due to its own weight. The electromagnet 22 having reached the limit of its time delay returns to rest, and through the link 3, it blocks the drawer 2 in the low position thus hiding access to the cylinder.

    Il faudra une autre impulsion du boítier de commande 12 pour libérer le tiroir et recommencer le cycle. 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 etc... et les différents identifiants correspondants.It will take another pulse from the command 12 to release the drawer and start the cycle again. In order to increase the security level of the conviction of the drawer, management electronics can be fitted with all types of readers, badges, smart cards, transponders etc ... and the different corresponding identifiers.

    Enfin, pour compenser les différences d'affleurement des cylindres, le protège cylindre sera fourni avec une cale d'épaisseur et des vis rallongées.Finally, to compensate for the differences flush with the cylinders, the cylinder protector will supplied with a shim and extended screws.

    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 boítier de commande indépendant, du type porte-clefs simplifie l'alimentation et permet un changement aisé des piles.The system described is simple and inexpensive since it is autonomous, without external wiring or internal crutch power supply. It can replace any standard cleaning plate, on the outside of the room, without possibility of disassembly. The control box independent, of the keyring type simplifies feeding and allows easy battery change.
