Abstract

Electromagnetic keeper rendering all locks tamperproof. To prevent the lock bolt 1 of a lock from returning, a pin 3 enters a hole, bored in the upper edge 5, when the key is turned for a second time. This pin is coupled with the movable core 4 of an electromagnet 2. When the current passes this pin is raised and thus releases the lock bolt. To actuate the switch of the electromagnet from the outside any currently available means, such as infrared radiation, ultrasound, UHF or even purely mechanical means may be used.

Description

Cache électro-magnétique rendant toutes les serrures
inviolables.Electro-magnetic cover making all locks
inviolable.

C'est au moment où le pêne d'une serrure entre dans l'ouverture de la gâche, que commence le blocage d'une porte. Le moyen le plus simple de bloquer une serrure consiste à empêcher tout mouvement du pêne (1) grâce à une goupille. (fig.l,2 et 3) Cette goupille (3) couplée avec la base du noyau mobile (4) d'un électro-aimant (2 ) pénètre dans un trou (5) forré sur la tranche supérieure du pêne, à l'endroit de l'impact pêne -goupille, au deuxième tour de clé. Cette goupille se retire, entrainée par le noyau mobile le temps que le courant passe. L'électro-aimant a les dimensions lui permettant de. s'intégrer dans une gache normale et fonctionne au courant alternatif 220 V ou au courant continu 12 ou 24 V.Le coin supérieur du pêne (6) et la goupille sont taillés en biseau fig.3 de telle sorte que le pêne dans son mouvement horizontal soulève la goupille , laquelle glisse un instant sur la tranche du pêne et après le deuxième tour de clé tombe dans le trou forré à cet effet. (5)
Le système d'interrupteur prévu pour mettre en mouvement le noyau mobile depuis l'extérieur, à travers la porte est laissé au choix de l'utilisateur.ll y a des moyens mécaniques, à infra-rouge, ultra-sons ou hyper-fréquences qui agissent depuis l'extérieur sur des capteurs placés à l'intérieur de l'appartement.It is at the moment when the bolt of a lock enters the opening of the strike, that the blocking of a door begins. The simplest way to block a lock is to prevent movement of the bolt (1) with a pin. (fig.l, 2 and 3) This pin (3) coupled with the base of the movable core (4) of an electromagnet (2) enters a hole (5) drilled on the upper edge of the bolt, at l location of the bolt-pin impact, on the second turn of the key. This pin withdraws, entrained by the moving core while the current passes. The electromagnet has the dimensions allowing it to. fit into a normal strike and operates on alternating current 220 V or direct current 12 or 24 V. The upper corner of the bolt (6) and the pin are cut in bevel fig.3 so that the bolt in its movement horizontal raises the pin, which slides for a moment on the edge of the bolt and after the second turn of the key falls into the hole drilled for this purpose. (5)
The switch system designed to set the moving core in motion from the outside, through the door is left to the user's choice. There are mechanical, infrared, ultrasonic or hyper-frequency means which act from the outside on sensors placed inside the apartment.

La simplicité de ce système de protection contre les infractions par les serrures, son prix modique et le fait qu'il s'applique à quasiment toutes les serrures déjà existantes, de la plus simple à la plus compliquée lui assurera une large place sur le marché. The simplicity of this system of protection against breaches by locks, its low price and the fact that it applies to almost all locks already existing, from the simplest to the most complicated will ensure it a large place on the market. .

A la partie supérieure du noyau, celle qui sort de la gâche, quand le noyau est soulevé, il y a un moyen de blocage pour mettre le système au repos. (7) At the upper part of the core, that which comes out of the strike, when the core is raised, there is a locking means to put the system at rest. (7)

Claims

1) Electro-magnetic strike making all locks tamper-proof, characterized in that it fits on almost all existing locks and has an electromagnet with a movable core fig.2 which rests on the upper edge of the bolt when the current does not pass and the lock is locked. At the location of the moving core - bolt impact, a pin is screwed into the bottom of the core and a corresponding hole drilled in the upper edge of the bolt (3 and 5).

2) Device according to claim 1, characterized in that the pin (3) and the end of the bolt are cut in bevel fig.3 so that the bolt in its horizontal movement lifts the pin and places it on the upper edge.
