Abstract

The invention relates to a deadbolt(1) of a lock comprising means for detecting the presence of the deadbolt (1) of the lock in a strike plate. The inventive deadlock (1) is provided with a plurality of unipolar magnets (3) which are arranged near the free end (4) thereof according to a predetermined configuration. The strike plate is provided with magnetic polarity detection units which are arranged in accordance with the magnets (3) position on the deadbolt (1) when it is deeply introduced into the strike plate. Said detection units are connected to an electronic control unit for signalling the presence of the deadbolt (1) in the strike plate when each detection unit detects the presence of the unipolar magnet (3) allocated thereto.

Description

Serrure à détection magnétique de fermetureMagnetic closing lock
La présente invention concerne une serrure à pêne dormant du type comprenant des moyens de détection de la présence du pêne de la serrure dans la gâche.The present invention relates to a deadbolt lock of the type comprising means for detecting the presence of the bolt of the lock in the strike.
Des serrures de ce type sont en particulier utilisées dans les centres pénitentiaires dans lesquels la fermeture est commandée à distance.Locks of this type are in particular used in penitentiary centers in which the closure is controlled remotely.
En général, les moyens de détection sont simplement constitués par un ou plusieurs contacteurs actionnés et maintenus fermés par le pêne. Ce système présente l'inconvénient d'être relativement facile à frauder par actionnement et maintien du ou des contacteurs en l'absence du pêne, de sorte que la centrale de surveillance ne constate pas d'anomalie, la serrure s'affichant verrouillée.In general, the detection means are simply constituted by one or more contactors actuated and kept closed by the bolt. This system has the drawback of being relatively easy to defraud by actuating and maintaining the contactor (s) in the absence of the bolt, so that the central monitoring station does not notice any anomaly, the lock being displayed locked.
L'invention vise à supprimer cet inconvénient grâce à un nouveau système de détection de la présence du pêne dans la gâche.The invention aims to eliminate this drawback thanks to a new system for detecting the presence of the bolt in the keeper.
À cet effet, la serrure selon l'invention est caractérisée par le fait que le pêne est muni, au voisinage de son extrémité libre, d'une pluralité d'aimants unipolaires disposés selon une configuration prédéterminée et la gâche est munie d'organes de détection de polarité magnétique disposés en concordance avec la position des aimants sur le pêne lorsque celui-ci est en fond de gâche, lesdits organes de détection étant reliés à une électronique de contrôle agencée pour émettre un signal de présence du pêne en fond de gâche lorsque chaque organe de détection a détecté la présence de l'aimant unipolaire qui lui est affecté.To this end, the lock according to the invention is characterized in that the bolt is provided, in the vicinity of its free end, with a plurality of unipolar magnets arranged in a predetermined configuration and the strike is provided with magnetic polarity detection members arranged in accordance with the position of the magnets on the bolt when the latter is at the bottom of the strike, said detection members being connected to a control electronics arranged to emit a signal for the presence of the bolt at the bottom of the strike plate when each detection member has detected the presence of the unipolar magnet which is assigned to it.
Avec la serrure selon l'invention, il est pratiquement impossible de simuler la présence du pêne dans la gâche, ce qui nécessiterait le positionnement en regard de chaque organe de détection d'un aimant ayant la polarité déterminée correspondante.With the lock according to the invention, it is practically impossible to simulate the presence of the bolt in the keeper, which would require positioning opposite each detection member of a magnet having the corresponding determined polarity.
Selon une forme de réalisation préférée de l'invention, les aimants unipolaires sont disposés sur les deux grandes faces du pêne. Les aimants sont de préférence noyés dans la masse du pêne.According to a preferred embodiment of the invention, the unipolar magnets are arranged on the two large faces of the bolt. The magnets are preferably embedded in the mass of the bolt.
Avantageusement, les organes de détection sont des détecteurs à effet Hall. Les détecteurs sont de préférence montés sur des cartes électroniques disposées dans le fond de gâche.Advantageously, the detection members are Hall effect detectors. The detectors are preferably mounted on electronic cards arranged in the strike bottom.
L'invention sera bien comprise à la lecture de la description suivante d'un exemple de réalisation en référence au dessin annexé dont la figure unique est une vue schématique en perspective d'un système de détection.The invention will be clearly understood on reading the following description of an exemplary embodiment with reference to the appended drawing, the single figure of which is a schematic perspective view of a detection system.
Le pêne dormant 1 de la serrure est muni, sur chacune de ses grandes faces 2, d'une ligne de trois aimants unipolaires 3 noyés au voisinage de son extrémité 4, à des emplacements prédéterminés, chaque aimant unipolaire 3 ayant une polarité prédéterminée. Dans l'exemple représenté, les aimants unipolaires 3 sont au nombre de trois sur chaque grande face, soit six au total. Il s'ensuit, pour le même positionnement des aimants 3, une combinaison très élevée de possibilités différentes, qui peut bien entendu être augmentée pratiquement à l'infini par des dispositions différentes des aimants unipolaires 3 pour des serrures différentes. Dans le fond de la gâche (non représentée) sont logées deux cartes électroniques 5, munies chacune de trois détecteurs de Hall (non représentés) disposés de telle manière que chaque détecteur est, lorsque le pêne 1 est en fond de gâche entre les cartes 5, en regard d'un aimant unipolaire 3 respectif du pêne 1.The deadbolt 1 of the lock is provided, on each of its large faces 2, with a line of three unipolar magnets 3 embedded in the vicinity of its end 4, at predetermined locations, each unipolar magnet 3 having a predetermined polarity. In the example shown, the unipolar magnets 3 are three in number on each large face, or six in total. It follows, for the same positioning of the magnets 3, a very high combination of different possibilities, which can of course be increased practically to infinity by different arrangements of the unipolar magnets 3 for different locks. In the bottom of the keeper (not shown) are housed two electronic cards 5, each provided with three Hall detectors (not shown) arranged in such a way that each detector is, when the bolt 1 is at the bottom of the keeper between the cards 5 , opposite a respective unipolar magnet 3 of the bolt 1.
Les cartes électroniques sont simplement raccordées à un central de lecture externe, par exemple la centrale de surveillance, de manière à transmettre à ce central un signal pour chaque détecteur de Hall détectant la présence, à l'emplacement correspondant, d'un aimant unipolaire 3 de la polarité déterminée sur le pêne 1. The electronic cards are simply connected to an external reading center, for example the monitoring center, so as to transmit to this center a signal for each Hall detector detecting the presence, at the corresponding location, of a unipolar magnet 3 of the polarity determined on the bolt 1.
