CA 2181906

An alarm-triggering locking mechanism for the lock and/or hinge area of a door to be secured or a window to be secured is proposed, which is embodied as a locking plate (23) which can be attached to a door or window frame by means of holding screws (27) embodied as the first blocking device. A second blocking device, which is harder to overcome by the effect of force, is embodied as at least one striker element (25) rigidly connected with the locking plate (23) and which, following the limited movement of the locking plate (23) in the opening direction, comes to rest against a counter-striker element (26) anchored on the door or window frame. An alarm, in particular a silent alarm, is triggered via radio or the telephone net after the first blocking device has been overcome. The burglar is thereafter delayed by the second blocking device, which makes it possible for security forces to reach the location of the break-in and to arrest the burglar while the break-in is still in progress.

L'invention concerne un système de verrouillage déclencheur d'alarme pour la zone de fermeture et/ou de charnière d'une porte ou d'une fenêtre dont l'accès doit être protégé. Ce système se présente sous forme de gâche (23) que l'on peut monter à l'aide de vis de retenue (27), comme premier système anti-effraction, sur un cadre de porte ou de fenêtre. Un second système anti-effraction plus difficile à forcer, se présente sous forme d'au moins une butée (25) fixée de manière rigide à la gâche (23) qui vient en contact avec au moins une contre-butée (26) ancrée dans le cadre de la porte ou de la fenêtre, après qu'un mouvement limité de la gâche ait été effectué. Après que le premier système anti-effraction a été forcé, une alarme est déclenchée, notamment une alarme silencieuse, par radio ou par le biais du réseau téléphonique. Le cambrioleur est ensuite retenu temporairement par le second système anti-effraction, ce qui laisse aux forces de l'ordre le temps de se rendre sur le lieu d'effraction et d'arrêter le cambrioleur pendant son forfait.
