Abstract

In addition to the conventional use of an electrical lock, the device can also, above all, be mounted on the doors of emergency exits, in order to ensure the control of these. A current cut-off generated either by a fire detection device or by any other alarm or simply by a caretaker is sufficient to ensure that the electromagnet (4), a finger (5) of which cooperates with a notch (6) of the bolt (3), ceases its retaining action, whereupon the bolt (3), the profile of which has a double slope, slides along its keeper and retracts under the action of a push on the door which opens without force. <IMAGE>

Description

La présente invention concerne un mécanisme adaptable sur les portes et particulièrement sur celles servant d'issue de secours afin d'en permettre le contrôle.The present invention relates to a mechanism that can be adapted to doors and particularly to those serving as an emergency exit in order to allow control thereof.

En effet, si celles-ci en cas d'urgence ou d'incendie doivent s'ouvrir par une simple poussée afin de permettre l'évacuation rapide des personnes qui se trouvent à l'intérieur, il est par contre souvent désirable, dans les conditions d'utilisation normales du local, que l'on puisse contrôler l'ouverture de ces issues, afin d'éviter les sorties frauduleuses ou l'accès par un complice déjà à l'intérieur.Indeed, if these in the event of an emergency or fire must open by a simple push in order to allow the rapid evacuation of the people who are inside, it is however often desirable, in the normal conditions of use of the premises, that we can control the opening of these exits, in order to avoid fraudulent exits or access by an accomplice already inside.

Pour assurer ce contrôle les réalisations actuellement connues ont pour objet de bloquer la poignée, ou la plaque de poussée ou la barre dite "barre anti-panique" qui normalement actionne l'efface du pène et l'ouverture de la porte. Or une difficulté survient lorsque, en cas de panique, la foule se déplace brusquement vers la porte. En effet dans ces dispositifs la commande d'effacement du pène n'est rendue possible qu'après basculement préalable de l'organe de blocage qui, en position active, l'immobilise à l'encontre de tout pivotement. Si du fait de la pression de la foule un effort continu est exercé sur le levier, celui-ci maintient en engagement mutuel le levier et l'organe de blocage, de telle sorte que l'action ultérieure sur ce dernier par commande mécanique ou électrique, ne permet pas toujours de désolidariser ces deux éléments, le levier restant coincé, empêchant l'ouverture de la porte. On risque que l'issue de secours, se trouvant bloquée, ne puisse plus être utilisée en cas d'accident avec les conséquences irrémédiables qui peuvent en résulter.To ensure this control, the currently known embodiments have the object of blocking the handle, or the thrust plate or the bar called "panic bar" which normally actuates the clearing of the bolt and the opening of the door. However, a difficulty arises when, in a panic, the crowd suddenly moves towards the door. In fact, in these devices, the command to erase the bolt is only made possible after prior tilting of the blocking member which, in the active position, immobilizes it against any pivoting. If due to crowd pressure a continuous force is exerted on the lever, the latter maintains in mutual engagement the lever and the locking member, so that the subsequent action on the latter by mechanical or electrical control , does not always allow to separate these two elements, the lever remaining stuck, preventing the door from opening. There is a risk that the emergency exit, being blocked, may no longer be used in the event of an accident with the irreversible consequences that may result.

Dans la présente invention, la porte est maintenue fermée par l'immobilisation d'un pène maintenu dans sa gâche par l'intermédiaire d'un électro-aimant, de type ventouse, sous tension.In the present invention, the door is kept closed by immobilizing a bolt held in its keeper by means of an electromagnet, of the suction cup type, under tension.

Il suffit d'une coupure de courant électrique générée, soit par l'appareil de détection incendie, soit par tout autre système d'alarme, soit tout simplement par un gardien, pour que l'électro-aimant cesse son action de maintien. Alors le pène, dont le profil est à double pente, glisse le long de sa gâche et s'efface sous l'action d'une poussée de la porte qui s'ouvre sans effort.An electrical power cut generated either by the fire detection device or by any other alarm system or simply by a guard is sufficient for the electromagnet to cease its holding action. Then the bolt, whose profile is double slope, slides along its strike and disappears under the action of a push of the door which opens effortlessly.

Différents avantages et caractéristiques de l'invention apparaissent sur la description suivante, faite à titre d'exemple non limitatif et se référant au dessin annexé, dans lequel :

  • la figure 1 représente une vue éclatée en position déverrouillée,
  • la figure 2 représente une vue éclatée en position déverrouillée,
  • les figures 3 à 6 représentent, en vue de dessus, différentes phases de l'ouverture d'une porte.
Various advantages and characteristics of the invention appear on the following description, given by way of nonlimiting example and referring to the appended drawing, in which:
  • FIG. 1 represents an exploded view in the unlocked position,
  • FIG. 2 represents an exploded view in the unlocked position,
  • Figures 3 to 6 show, in top view, different phases of the opening of a door.

Sur la planche n° I sont représentées (en éclaté partiel) les principales parties d'une réalisation pratique de l'invention.On plate n ° I are represented (in partial exploded view) the main parts of a practical embodiment of the invention.

On voit donc en fig. 1 l'electro-aimant de maintien dont la partie supérieure 2 est verrouillée en rotation sur le corps dudit électro-aimant, par l'intermédiaire de billes en effet cette partie supérieure 2 devient solidaire du corps de l'électro-aimant lorsque celui-ci est sous tension, ces billes 4, étant insérées entre le corps de l'électro-aimant et ladite partie supérieure 2, se trouvent coincées dans des alvéoles aménagées mi-partie supérieure, mi-électro-aimant, interdisant ainsi tout glissement en rotation de la plaque supérieure 2.We therefore see in fig. 1 the holding electromagnet whose upper part 2 is locked in rotation on the body of said electromagnet, by means of balls in effect this upper part 2 becomes integral with the body of the electromagnet when this- this is under tension, these balls 4, being inserted between the body of the electromagnet and said upper part 2, are wedged in cells arranged in the upper part, in the electromagnet, thus preventing any sliding in rotation of the top plate 2.

Or on voit également que la partie supérieure est munie d'un doigt 5 et que ce doigt vient épouser une encoche transversale creusée dans la face interne du pène 3 et que l'on voit en 6 sur les figures 1 et 2 des dessins en éclaté. Sur la figure 1, l'électro-aimant est sous tension, le doigt 5 dans son encoche immobilisant le pène en fermeture. Sur la figure 2, la tension électrique ayant été coupée, la partie supérieure 2 libérée peut donc tourner ; il suffit qu'une poussée soit exercée sur la porte pour comprimer les ressorts 7 du pène qui s'efface, permettant l'ouverture de l'issue. En fin d'opération les ressorts 7 et le ressort 8 rameneront le pène, et la partie supérieure 2 surmonté de son doigt dans la position de départ.However, we also see that the upper part is provided with a finger 5 and that this finger comes to marry a transverse notch hollowed out in the internal face of the bolt 3 and which we see at 6 in FIGS. 1 and 2 exploded drawings . In FIG. 1, the electromagnet is energized, the finger 5 in its notch immobilizing the bolt when closing. In FIG. 2, the electric voltage having been cut, the released upper part 2 can therefore rotate; it suffices that a push is exerted on the door to compress the springs 7 of the bolt which disappears, allowing the opening of the exit. At the end of the operation the springs 7 and the spring 8 will bring the bolt, and the upper part 2 surmounted by his finger in the starting position.

Les schémas des figures 3 à 6 montrent clairement le mode de fonctionnement du dispositif ; dans la phase 1, figure 3, la ventouse électro-magnétique est sous tension et le doigt 5 représenté ici par sa section en hachuré est bloqué dans l'encoche pratiquée dans la boutonnière 12 creusé dans la partie inférieure du pène qu'il maintient engagé dans sa gâche 10, maintenant ainsi la porte verrouillée.The diagrams in Figures 3 to 6 clearly show the mode of operation of the device; in phase 1, FIG. 3, the electromagnetic suction cup is under tension and the finger 5 represented here by its cross-hatched section is locked in the notch formed in the buttonhole 12 hollowed out in the lower part of the bolt which it maintains engaged in its keeper 10, thus keeping the door locked.

Dans la phase 2, figure 4, le courant étant coupé, il suffit d'une poussée sur la porte, et la ventouse électro-magnétique se trouvant libre en rotation, le doigt peut se dégager de l'encoche et glisser dans la boutonnière 12 du pène libérant celui-ci immédiatement pour l'effacement pour que ladite porte s'ouvre sous la moindre poussée. Il est à noter que la coupure de courant peut être générée par détection incendie, bris de glace, ou tout simplement par un gardien.In phase 2, figure 4, the current being cut, it is enough a push on the door, and the electromagnetic suction cup being free in rotation, the finger can be released from the notch and slide in the buttonhole 12 bolt releasing it immediately for erasure so that said door opens under the slightest push. It should be noted that the power cut can be generated by fire detection, glass breakage, or simply by a guard.

En figure 5, porte toujours en phase d'ouverture et effacement total du pène.In Figure 5, door always in the opening and total erasure of the bolt.

En figure 6, porte ouverte mais en approche de fermeture.In Figure 6, door open but approaching closure.

En figure 11, sont représentés schématiquement les deux fils de dérivation menant vers bris de glace, détection incendie ou poste de contrôle.In FIG. 11, the two bypass wires are shown schematically leading towards glass breakage, fire detection or control station.
