Abstract

Mechanism comprises oscillating finger (1) moved by handles of lock. In off-position, finger cannot oscillate as it is blocked by tilter (4). Tilter is maintained in horizontal position by permanent magnet (5) coupled to electromagnet (9). When electric current goes through solenoid of electromagnet, magnetic filed counteracts effect of magnet, hence core exits under effect of spring (6). Mechanical energy from user using handle is used to replace and secure tilter in horizontal position.

Description

La présente invention concerne un dispositif pour commander le blocage et le déblocage des serrures électriques en consommant un minimum d'énergie. The present invention relates to a device for controlling the locking and unlocking of electric locks while consuming a minimum of energy.

Bien que ce procédé s'applique à toutes les serrures à commande électrique, il est particulièrement recommandé pour les systèmes autonomes compte tenu de la faible énergie . demandée pour le déclencher. Although this process applies to all electrically operated locks, it is particularly recommended for autonomous systems due to the low energy. requested to trigger it.

Le dessin annexé Figure 1 illustre l'invention - la figure 1 représente en traits gras le dispositif en position repos pêne sorti - elle représentez en traits mixtes le dispositif en position pêne rentré . The attached drawing Figure 1 illustrates the invention - Figure 1 shows in bold lines the device in the bolt out position - it shows in dashed lines the device in the retracted bolt position.

En référence à ces dessins, le dispositif comporte un doigt oscillant (1) mu par les poignées de la serrure. Ces poignéés sont reliées par un carré de manoeuvre (2) que l'on ' retrouve dans le doigt oscillant (1). With reference to these drawings, the device comprises an oscillating finger (1) moved by the handles of the lock. These handles are connected by an operating square (2) which is found in the oscillating finger (1).

Le doigt (1) lorsqu'il oscille, donne un mouvement linéaire ou pêne (3). Phase 1 En position repos, le doigt (2) ne peut osciller car il est bloqué par le culbuteur (4). Le culbuteur (4) est maintenu en position horizontale par un aimant permanent (5) couplé à un électro-aimant (9). La position rentrée correspond donc au repos . The finger (1) when it oscillates, gives a linear movement or bolt (3). Phase 1 In the rest position, the finger (2) cannot oscillate because it is blocked by the rocker arm (4). The rocker arm (4) is held in a horizontal position by a permanent magnet (5) coupled to an electromagnet (9). The retracted position therefore corresponds to rest.

Si l'on fait circuler un courant électrique dans le solénoïde de l'électro-aimant (9), le champ magnétique annule l'effet de l'aimant; le noyau sort alors sous l'effet du ressort (6). If an electric current is circulated in the solenoid of the electromagnet (9), the magnetic field cancels the effect of the magnet; the core then exits under the effect of the spring (6).

Pour simplifier l'explication de la fiabilité du système, et à titre d'exemple on peut donner les valeurs numériques suivantes - l'aimant de maintien (5) lorsqu'il est en position repos c'est à dire rentré à une force de collage du culbuteur (4)de 10 N. To simplify the explanation of the reliability of the system, and by way of example, the following numerical values can be given - the holding magnet (5) when it is in the rest position, ie returned to a force of bonding the rocker arm (4) by 10 N.

- le ressort antagoniste (6) qui tire en opposition à l'aimant a une force de 2 N. - le système est donc stable en position fermée. - the opposing spring (6) which pulls in opposition to the magnet has a force of 2 N. - the system is therefore stable in the closed position.

- lorsque l'on supprime l'effet de l'aimant par exitation du solénoïde (9), le ressort (6) ne doit vaincre que le frottement du pivot (7)soit 0.4N. - when we remove the effect of the magnet by excitation of the solenoid (9), the spring (6) must overcome only the friction of the pivot (7) is 0.4N.

# on notera que l'exitation du solénoïde peut cesser dès que le noyau est sorti du champ de l'aimant.  # note that the excitation of the solenoid can cease as soon as the nucleus has left the field of the magnet.

# on notera également que le système garde en mémoire cette position sans apport d'énergie supplémentaire que celle du décollage Phase 2 - le culbuteur étant descendu, le doigt (1) peut maintenant osciller dans le sens horaire et par le fait déplacer le pêne (3) de gauche à droite ce qui correspond à l'ouverture.  # it will also be noted that the system keeps this position in memory without adding any additional energy than that of take-off Phase 2 - the rocker arm being lowered, the finger (1) can now oscillate clockwise and thereby move the bolt ( 3) from left to right which corresponds to the opening.

- lorsque le doigt oscillant arrive en fin de course à droite *le pêne (3) est complètement rentré #1a lame ressort (8) qui est solidaire du doigt (1) se trouve en position inclinée et de ce fait remonte le culbuteur (4) ainsi que le noyau de l'aimant. - when the oscillating finger reaches the end of the right stroke * the bolt (3) is fully retracted # 1a spring blade (8) which is integral with the finger (1) is in the inclined position and therefore raises the rocker arm (4 ) as well as the magnet core.

Dès que celui-ci rentre dans le champ magnétique de l'aimant, il se recolle. On utilise donc l'énergie mécanique de la personne qui actionne la poignée pour replacer le culbuteur (4) en position horizontale et donc recoller le noyau de l'aimant et le culbuteur (4) qui lui est assujetti. As soon as it enters the magnetic field of the magnet, it sticks together. We therefore use the mechanical energy of the person who actuates the handle to replace the rocker arm (4) in a horizontal position and therefore re-glue the magnet core and the rocker arm (4) which is attached to it.

Lorsque le doigt oscillant retrouve sa position initiale, il tire légèrement sur le noyau pour le crantage mais ne sort pas du champ de l'aimant. When the oscillating finger returns to its initial position, it pulls slightly on the core for the notching but does not leave the field of the magnet.

On notera que cette version A est très économique en énergie puisqu'une seule impulsion suffit pour faire descendre le culbuteur (4) et pour le remonter on utilise l'énergie humaine. Cette version est particulièrement destinée aux contrôles d'accès autonomes. Note that this version A is very economical in energy since a single pulse is enough to lower the rocker arm (4) and to raise it we use human energy. This version is particularly intended for autonomous access controls.

Selon une variante B, on supprime la languette ressort (8) ou on annule son effet mécaniquement; le culbuteur reste dônc en position basse. La serrure est déverrouillée ' définitivement. According to a variant B, the spring tab (8) is removed or its effect is canceled mechanically; the rocker arm therefore remains in the low position. The lock is permanently unlocked.

Pour provoquer son reverrouillage, il suffit d'envoyer une tension inverse sur le solénoïde . Ce champ électrique provoqué renforce alors le champ de l'aimant et l'addition des 2 forces fait remonter le culbuteur (4). To cause relocking, simply send a reverse voltage to the solenoid. This electric field caused then strengthens the field of the magnet and the addition of the 2 forces brings up the rocker arm (4).

Cette variante B est particulièrement bien adaptée aux contrôles d'accès avec passage libre par exemple pendant les heures de travail et verrouillage la nuit. This variant B is particularly well suited to access controls with free passage, for example during working hours and locking at night.

On note que le culbuteur de blocage (4) est de faible masse et équilibbré également de part et d'autre de son axe par la masse additive (10) afin d'être insensible aux accélérations dues aux chocs. It is noted that the blocking rocker (4) is of low mass and balanced also on either side of its axis by the additive mass (10) in order to be insensitive to accelerations due to shocks.

On note que le culbuteur de blocage peut être actionné par un moyen mécanique (11) du type barillet et clef comme moyen de secours . Plusieurs modèles de barillets ou actionneurs mécaniques non représentés sur la figure 1 peuvent se trouver le long du culbuteur (4) et rendre ainsi la serrure manoeuvrable avec des mécaniques de marques et types différents. Note that the blocking rocker can be actuated by mechanical means (11) of the barrel and key type as an emergency means. Several models of barrels or mechanical actuators not shown in FIG. 1 can be found along the rocker arm (4) and thus make the lock operable with mechanics of different brands and types.

On note enfin que le mouvement rotatif de la poignée peut entrainer un générateur de courant électrique (non représenté sur la figure 1) qui tiendra chargé un accumulateur ; cette disposition rendant la serrure entièrement autonome.Finally, note that the rotary movement of the handle can cause an electric current generator (not shown in FIG. 1) which will hold an accumulator charged; this arrangement making the lock entirely autonomous.
