Definitions
- the present invention relates to the means of prevention against the breaking of locks.
- the method according to the invention radically eliminates the possibility of opening or destroying the lock of the door of a room by detecting the attempted break-in with the aid of an electronic delay alarm, the latter having the effect of '' grant a reprieve to the authorized person so that he can enter or leave said room without the effective alarm being manifested, associated with an electric switch whose control member does not allow access to the lock without giving the start signal to the alarm.
- the electrical switch is placed outside the lock and closes the alarm circuit before the key is inserted into the lock, conditioning access to the latter. Note the deterrent aspect of the device according to the - process which makes any attempted break-in unnecessary and very unlikely.
- Figure 1 shows the device at rest, that is to say with protected lock.
- Figure 2 the device with closed detection circuit, that is to say with free access to the lock.
- Figure 3 a perspective view of the system at rest.
- the device comprises a switch body 1, a switch control in the form of a movable plate 2 provided with a finger 3 actuating electrical contacts (a / b) mounted on a flexible blade and normally closed.
- the wafer-shaped switch control prohibits access to the lock 4 and, by means of finger 3 pressing on the flexible blade which bears the contact (b), causes said blade to bend and thus separates the contacts (a / b) which opens the electrical alarm circuit. If you want to reach the lock 4, you must lift the switch control plate 2: finger 3 releases the flexible blade carrying the contact (b) and the latter sticks to the contact (a), which closes the circuit electric alarm.
- the device associated with the electronic delay alarm can be used in all cases where one wants to protect a lock.
- the vulnerability of car locks makes application to the automobile particularly interesting.

Description
- La présente invention concerne les moyens de prévention contre l'effraction des serrures.
- Les moyens habituellement utilisés sont intimement liés aux caractéristiques de la serrure et à sa sécurité intrinsèque et bien qu'il existe une multitude de types de serrure, les systèmes les plus sophistiqués ne découragent pas les spécialistes de l'effraction qui probablement mettent un point d'honneur à tenter leur chance ce qui a pour conséquence directe sinon d'ouvrir dumoins de détruire le mécanisme qui résiste à leurs efforts. Certains dispositifs tels ceux divulgués dans les brevets FR-A-2216829 et FR-A-2168972 comportent un circuit électrique fermé par et après l'introduction de la clef (ou de tout autre objet) dans la serrure à l'intérieur de laquelle se trouvent le ou les interrupteurs actionnés. Il s'agit de dispositifs compliqués, d'un prix de revient élevé, qui n'évitent pas un début d'effraction.
- Le procédé selon l'invention supprime radicalement la possibilite d'ouvrir ou de détruire la serrure de la porte d'un local en détectant la tentative d'effraction à l'aide d'une alarme électronique à temporisation celle-ci ayant pour effet d'accorder un sursis à la personne autorisée pour qu'elle puisse entrer ou sortir dudit local sans que l'alarme effective ne se manifeste, associée à un interrupteur électrique dont l'organe de commande ne permet pas l'accès à la serrure sans donner le signal de départ à l'alarme. Dans un dispositif pour la mise en oeuvre du procédé l'interrupteur électrique est placé à l'extérieur de la serrure et ferme le circuit d'alarme avant l'introduction de la clef dans la serrure en conditionnant l'accès à cette dernière. Il faut noter l'aspect dissuasif du dispositif selon le - rocédé qui rend toute tentative d'effraction inutite et très peu probable.
- Les dessins annexés sont des vues schématiques en coupe d'un exemple de réalisation d'un dispositif pour la mise en oeuvre du procédé.
- La figure 1 représente le dispositif au repos, c'est à dire avec serrure protégée. La figure 2 le dispositif avec circuit de détection fermé, c'est à dire avec accès libre à la serrure. La figure 3 une vue en perspective du système au repos.
- Tel qu'il est représenté le dispositif comporte un corps d'interrupteur 1, une commande d'interrupteur en forme de plaquette mobile 2 munie d'un doigt 3 actionnant des contacts électriques (a/b) montés sur lame souple et normalement fermés.
- Au repos, la commande d'interrupteur en forme de plaquette interdit l'accès à la serrure 4 et, par l'intermédiaire du doigt 3 appuyant sur la lame souple qui porte le contact (b), fait plier ladite lame et sépare ainsi les contacts (a/b) ce qui ouvre le circuit électrique d'alarme. Si l'on veut atteindre la serrure 4, il faut soulever la plaquette 2 de commande d'interrupteur: le doigt 3 libère la lame souple portant le contact (b) et ce dernier colle au contact (a), ce qui ferme le circuit électrique d'alarme.
- Le dispositif associé à l'alarme électronique à temporisation peut etre utilisé dans tous les cas où l'on veut protéger une serrure. La vulnérabilité des serrures de voiture rend l'application à l'automobile particulièrement intéressante.
