Abstract

The electromagnetic blocking device includes an electromagnet (3) whose armature is attached to a right angle bracket (5). A spring (4) around the armature urges this bracket outwards. The free end of the bracket is arranged to engage in a slot (19) cut into the bolt (7) of the lock, between the lock and the retaining plate attached to the door frame. If an incorrect key is used to operate the lock, the key is allowed to rotate through a quarter turn, thus bringing the slot immediately below the bracket. The spring then urges the bracket into the slot preventing further movement of the lock or the lock cylinder. The key may not then be removed until an appropriate connection is made to the electronic circuit which controls the electromagnet, allowing the armature to be withdrawn.

Description

DISPOSITIF DE BLOCAGE ELECTRO-MBGNETIQoE SUR SERRURE
RENDANT PRISONNIERE LA FAUSSE CLEF DANS LE CANON
L'invention concerne un dispositif de blocage magnétique appligué sur barre ou pêne de toute serrure tout en gardant prisonnière la fausse clef à l'intérieur du canon. Ce système rend de ce fait toutes les serrures incrochetables.ELECTRO-MBGNETIQoE LOCKING DEVICE ON LOCK
MAKING THE WRONG KEY IN THE CANON PRISONER
The invention relates to a magnetic locking device applied to the bar or bolt of any lock while keeping the false key trapped inside the barrel. This system therefore makes all locks hookable.

L'invention est constituée d'une partie mécanique (fig 1 et 2) et d'une partie électronique (fig 3) commandant l'électro-aimant (3). The invention consists of a mechanical part (fig 1 and 2) and an electronic part (fig 3) controlling the electromagnet (3).

La partie mécanique du système est constituée d'un électroaimant (3) muni dtun ressort de rappel (4) et d'une équerre (5) l'équerre est percée d'un trou (8). The mechanical part of the system consists of an electromagnet (3) provided with a return spring (4) and a bracket (5) the bracket is pierced with a hole (8).

Pour une serrure haute et basse (fig 1) l'équerre (5) est fixée sur une barre (6). For a high and low lock (fig 1) the bracket (5) is fixed on a bar (6).

Pour une serrure simple (fig 2) l'équerre (5) est fixée sur l'é- lectro-aimant (3) et le pêne (7) entaillé d'un trait de scie (19).  For a simple lock (fig 2) the bracket (5) is fixed on the electromagnet (3) and the bolt (7) notched with a saw cut (19).

Dans le cas de l'introduction d'une fausse clef, parapluie ou tout autre moyen, l'intru ouvre la serrure d'un quart de tour, l'é- lectro-aimant (3) muni de son ressort (4) entre dans le trou (8) de l'équerre (5) pour les serrés haute et basse (fig t).  In the case of the introduction of a false key, umbrella or any other means, the intruder opens the lock a quarter of a turn, the electromagnet (3) provided with its spring (4) between in the hole (8) of the bracket (5) for the high and low clamps (fig t).

Pour lei serrures simples (fig 2) 'est l'équerre (5) qui entre dans le trait de scie (19) du pêne (7), la serrure se trouve ainsi bloquée et la fausse clef ne peut être ressortie du canon. For simple locks (fig 2) 'is the square (5) which enters the saw line (19) of the bolt (7), the lock is thus blocked and the false key can not be released from the barrel.

La partie électrique oommande l'électro-aimant (3) se composant d'une clef Jack (9) à deux résistances (10) et d'un circuit électronique (plan 2/2). The electrical part controls the electromagnet (3) consisting of a Jack key (9) with two resistors (10) and an electronic circuit (plane 2/2).

Cette clef (9) placée dans la prise correspondante est lue pour chaque résistance (10) par deux amplis opérationnels (11) montés en comparateurs inverses qui vérifient les tensions de pont des résis- tances (10). This key (9) placed in the corresponding socket is read for each resistor (10) by two operational amplifiers (11) mounted in reverse comparators which check the bridge voltages of the resistors (10).

Chaque comparateur inverse est relié à une porte ET (12) et les sorties de ces deux portes ET sont reliées à une suivante (13). Each inverse comparator is connected to an AND gate (12) and the outputs of these two AND gates are connected to a next one (13).

Un temporisateur (14) est également activé. A timer (14) is also activated.

Quand la clef Jack (9) est enfoncée dans la prise, la sortie de ce temporisateur et celle de la troisième porte ET (13) sont reliées à une quatrième porte ET. When the Jack key (9) is pressed into the socket, the output of this timer and that of the third AND gate (13) are connected to a fourth AND gate.

Quand la sortie de cette quatrième porte ET (15) passe à l'état 1 (les deux résistances (10) dtant bonnes et le temporisateur (14) étant activé) elle rend conducteur un transistor (16) qui lui même commande un relais (17), ce relais rend actif l'électro-aimant (3). When the output of this fourth AND gate (15) goes to state 1 (the two resistors (10) being good and the timer (14) being activated) it makes a transistor (16) conductive which itself controls a relay ( 17), this relay activates the electromagnet (3).

L'alimentation du système est autonome grâce à une batterie (18) et la consommation au repos est nulle.  The power supply of the system is autonomous thanks to a battery (18) and the consumption at rest is zero.
