Abstract
Description
Les locaux collectifs accueillant le public comportent de issues de secours destinées à assurer leur évacuation rapide
en cas de nécessité.Collective premises welcoming the public have emergency exits intended to ensure their rapid evacuation
if necessary.
Pour celà, ils sont munis de barres dites "anti-panique" permettant un dévérrouillage intérieur par une simple poussée mais interdisant le déverrouillage de l'extérieur.For this, they are provided with bars called "anti-panic" allowing an unlocking inside by a simple push but prohibiting unlocking from the outside.
L'inconvénient d'un tel système est qu'il rend ces issues accessibles en permanence, même s'il n'y a pas de danger et que, par conséquent, des personnes indélicates peuvent sortir, par exemple, en emportant des marchandises non payées.The disadvantage of such a system is that it makes these exits permanently accessible, even if there is no danger and that, consequently, unwise people can go out, for example, by carrying goods not paid.
Le but du présent verrou électrique est de permettre les manoeuvres de verrouillage et de déverrouillage à distance des issues de secours tout en assurant un déverrouillage général, en cas de danger, sans apport d'énergie.The purpose of this electric lock is to allow remote locking and unlocking maneuvers of emergency exits while ensuring general unlocking, in the event of danger, without energy supply.
Pour celà, le principe consiste à monter le pêne du verrou de telle manière qu'en absence de courant électrique sa position stable soit l'ouverture.For this, the principle is to mount the bolt of the lock so that in the absence of electric current its stable position is the opening.
Autrement dit, si le courant vient à manquer, le verrou s'ouvrira naturellement sous l'effet d'un ressort de rappel.In other words, if the current fails, the lock will open naturally under the effect of a return spring.
Pour provoquer sa fermeture, om assure son déplacement vers l'avant au moyen d'un moteur électrique à courant continu entrainant une vis sans fin qui pénêtre librement à l'intérieur du pêne.To cause its closing, om ensures its displacement forwards by means of a direct current electric motor driving a worm which penetrates freely inside the bolt.
Si bien que l'écrou qui est entrainé par la vis sans fin n'est pas solidaire du pêne. Il n'assurera son déplacement que dans le sens de la fermeture.So that the nut which is driven by the worm is not secured to the bolt. It will only move in the direction of closing.
Donc, à la mise sous tension du verrou, l'écrou se contente de pousser le pêne vers l'avant en bandant le ressort de rappel. So when the bolt is tensioned, the nut simply pushes the latch forward by bandaging the return spring.
Quand le pêne arrive en fin de course avant, il est pris en charge par un électro-aimant annulaire qui le maintient en position fermée tant qu'il est alimenté en électricité.When the bolt reaches the front end of the stroke, it is supported by an annular electromagnet which keeps it in the closed position as long as it is supplied with electricity.
En meme temps un interrupteur de fin de course, actionne par 1 avance du pêne, provoque le retour dans sa position initiale de l'écrou entrainé par la vis sans fin et le moteur électrique
Quand il a atteint sa position initiale, l'écrou en question actionne un interrutpeur de fin de course qui assure l'arrêt du moteur.At the same time a limit switch, actuated by 1 advance of the bolt, causes the return driven to its initial position of the nut driven by the worm and the electric motor
When it has reached its initial position, the nut in question actuates a limit switch which ensures the engine stops.
Le fait de couper le courant par tout moyen extérieur, désexcite l'électro-aimant qui relache ainsi le pêne.The fact of cutting the current by any external means, de-energizes the electromagnet which releases the bolt.
Ce dernier revient alors à sa position d'ouverture sous l'effet du ressort.The latter then returns to its open position under the effect of the spring.
La figure 1 représente une vue en plan du verrou. en position "fermé", capot enlevé.La figure 2 représente une vue en élévation coupe du même verrou, en position"ouvert".Figure 1 shows a plan view of the lock. in the "closed" position, cover removed. FIG. 2 represents a sectional elevation view of the same lock, in the "open" position.
Le verrou est constitué d'un chassis en tôle pliée comportant 3 faces d"appui. The lock consists of a folded sheet frame with 3 support faces.
Un moteur électrique à courant continu M est fixé par bride sur la face d'appui arrière et son axe traverse cette face d'appui.A direct current electric motor M is fixed by a flange to the rear support face and its axis passes through this support face.
La vis sans fin en acier V est solidaire de l'axe du moteur et est entrainée en rotation par lui
La vis sans fin V entraine en translation l'écrou en bronze E dont la rotation est interdite par tout moyen ad hoc, par exemple par une vis sans tête se déplapant linéairement dans une rainure appropriée pratiquée dans le circuit imprimé placé au fond du chassis.The V steel worm is integral with the motor axis and is rotated by it
The worm screw V drives in translation the bronze nut E whose rotation is prohibited by any ad hoc means, for example by a headless screw moving linearly in an appropriate groove made in the printed circuit placed at the bottom of the chassis.
L'écrou E comports une butée destinée à actionner l'inter rupteur de fin de course I2 à son retour en position arrière.The nut E includes a stop intended to actuate the limit switch I2 on its return to the rear position.
La face d'appui avant comporte un trou servant de premier palier à l'équipage mobile constitué par le pêne P.The front bearing face has a hole serving as the first bearing for the mobile assembly constituted by the bolt P.
Le pêne P comporte une partie cylindrique de fort diamêtre destinée à supporter les efforts d'effraction et, à sa partie arrière, un tube T en matière non magnétique, de diamêtre plus faible destiné à assurer son guidage par l'intermédiaire du trou de diamêtre correspondant qui lui sert de palier dans la face d'appui intermédiaire.The bolt P has a cylindrical part of large diameter intended to withstand burglary forces and, at its rear part, a tube T made of non-magnetic material, of smaller diameter intended to guide it through the diameter hole corresponding which serves as a bearing in the intermediate support face.
A la partie avant du pêne située au delà de la face d'appui avant, sur une longueur égale à sa course, on trouve une conicité de 3 % destinée à faciliter l'ouverture du verrou si une pression s'exerce sur la porte.At the front part of the bolt located beyond the front bearing face, over a length equal to its stroke, there is a taper of 3% intended to facilitate the opening of the latch if pressure is exerted on the door.
La vis sans fin V tournera librement à l'intérieur du tube T.The worm screw V will rotate freely inside the tube T.
Le ressort R, enfilé autour de la partie avant du pêne P, s'appuyera d'une part sur la face d'appui avant et d'autre part sur un épaulement placé à l'arrière de la partie de fort diamêtre du pêne P.The spring R, threaded around the front part of the bolt P, will rest on the one hand on the front bearing face and on the other hand on a shoulder placed at the rear of the part of large diameter of the bolt P .
Au repos, le ressort R provoquera le retour du pêne, puis son maintien en position d'ouverture.At rest, the spring R will cause the bolt to return, then keep it in the open position.
En outre, un électro-aimant annulaire A, placé sur la face d'appui intermédiaire et fixé à celle-ci du coté de la vis sans fin, est traversé par le tube T de la partie arrière du pêne P.In addition, an annular electromagnet A, placed on the intermediate support face and fixed to the latter on the side of the worm, is crossed by the tube T of the rear part of the bolt P.
A l'extrémité du tube T, se trouve un disque D, solidaire du tube, destiné à assurer la continuité magnétique de l'éléctroaiamnt A quand le pene est en position d'ouverture en assurant ainsi son maintien dans cette position tant que l'alimentation électrique de l'électro-aimant est assurée.At the end of the tube T, there is a disc D, integral with the tube, intended to ensure the magnetic continuity of the electroaiamnt A when the bolt is in the open position thereby ensuring its maintenance in this position as long as the power supply of the electromagnet is ensured.
La rotation du disque D est interdite par tout moyen ad hoc, par exemple par une vis sans tête se déplaçant dans une rainure appropriée pratiquée dans le circuit imprimé placé au fond du chassis du verrou.The rotation of the disk D is prohibited by any ad hoc means, for example by a headless screw moving in an appropriate groove made in the printed circuit placed at the bottom of the frame of the lock.
Enfin, sur le disque D, se trouve une butée destinée à actionner, dans le sens de l'ouverture, l'interrupteur de fin de course
Il .Finally, on disk D, there is a stop intended to actuate, in the direction of opening, the limit switch.
He .
Les 2 interrupteurs de fin de course I1 et I2, tous les composants électroniques destinés à assurer le fonctionnement du système ainsi que les bornes de raccordement, sont placés sur un même circuit imprimé situé dans le fond du chassis du verrou entre la face d'appui arrière et la face d'appui intermédiaire.The 2 limit switches I1 and I2, all the electronic components intended to ensure the functioning of the system as well as the connection terminals, are placed on the same printed circuit located in the bottom of the frame of the lock between the support face rear and the intermediate support face.
La figurm 3 représente le schéma électrique du dispositif.FIG. 3 represents the electrical diagram of the device.
Sans alimentation électrique, le verrou est ouvert, et l'écrou
E est en position arrière.Without power supply, the lock is open, and the nut
E is in rear position.
L'interrupteur de fin de course Il est fermé et l'interrupteurde fin de course I2 est ouvert.The limit switch It is closed and the limit switch I2 is open.
Le relais Re est au repos .Relay Re is at rest.
Le fait de mettre le courant alimente la bobine du relais Re au travers de l'interrupteur de fin de course I1.Switching on the current supplies the coil of the relay Re through the limit switch I1.
On alimente également la bobine de l'électro-aimant A.The coil of the electromagnet A is also supplied.
Le relais Re monte et, par l'intermédiaire de ses 2 contacts inverseurs, alimente le moteur dans le sens de la fermeture du verrou au travers de la diode Di qui, pour le sens correspondant du courant, court-circuite l'interrupteur de fin de course I2 alors ouvert.The relay Re goes up and, via its 2 change-over contacts, supplies the motor in the direction of closing the latch through the diode Di which, for the corresponding direction of current, short-circuits the end switch stroke I2 then open.
L'écrou E se déplace linéairement le long de la vis sans fin V et, en s'appuyant sur le disque D provoque l'avance du pêne P dans le sens de la fermeture tout en bandant ainsi le ressort
R . The nut E moves linearly along the worm screw V and, by pressing on the disc D causes the bolt P to advance in the closing direction while thus tightening the spring
R.
Le disque D avance jusqu'à rentrer en contact avec l'armature de l'électro-aiamnt A qui le maintient dans cette position.The disc D advances until it comes into contact with the armature of the electro-aiamnt A which keeps it in this position.
En même temps, la butée du disque D actionne l'interrupteur de fin de course Ii qui coupe l'alimentation de la bobine du relais Re.At the same time, the stop of the disc D actuates the limit switch Ii which cuts the supply of the coil of the relay Re.
Celui-ci retombe et inverse ainsi les polarités aux bornes du moteur M.It drops and thus reverses the polarities at the terminals of the motor M.
Ce dernier démarre donc en sens inverse jusqu'à ce que la butée de l'écrou E actionne l'interrupteur de fin de course 12 qui coupe l'alimentation du moteur M du fait que la diode Di est polarisée dans le sens opposé du courant.The latter therefore starts in the opposite direction until the stop of the nut E actuates the limit switch 12 which cuts the power supply to the motor M because the diode Di is polarized in the opposite direction of the current .
Le moteur M s'arrête alors, entrainant ainsi l'arrêt de l'écrou E.The motor M then stops, thus causing the nut E to stop.
Pour provoquer l'ouverture du verrou, il suffira de couper son alimentation.To cause the lock to open, simply cut off its power.
L'électro-aimant A étant désexcité, lachera le pêne qui, libéré, reviendra immédiatement en position d'ouverture sous l'action du ressort R.The electromagnet A being de-energized, will release the bolt which, released, will immediately return to the open position under the action of the spring R.
Le bouton poussoir à ouverture Bp, placé sur le capot du verrou, permet son ouverture locale.The push button with opening Bp, placed on the cover of the lock, allows its local opening.
Une borne du bouton poussoir Bp est sortie pour permettre la mise en service ou la mise hors service à distance de la commande locale qu'il constitue.A terminal of the push button Bp is out to allow the remote control to be put into service or out of service.
Un contact magnétique C, fixé au capot du verrou et dont l'aimant est fixé à la gâche, interdit la fermeture du verrou si la porte est ouverte et provoque sa refermeture automatique à la fermeture de la porte si le verrou est alimenté.A magnetic contact C, fixed to the cover of the lock and whose magnet is fixed to the strike, prevents closing of the lock if the door is open and causes its automatic reclosing when the door is closed if the lock is powered.
Une temporisation électronique réalisée avec la transistor du type NPN TR, les résistances R1, R2, R3 et le condensateur
Co, provoque la chute du relais Re si, au bout de quelques secondes la verrou ne s'est pas totalement fermé. An electronic timer produced with the NPN TR type transistor, the resistors R1, R2, R3 and the capacitor
Co, causes the relay Re to fall if, after a few seconds, the lock has not fully closed.
Le moteur M démarre alors en sens inverse et l'ensemble pêne P et écrou E revient à sa position d'ouverture initiale.The engine M then starts in the opposite direction and the bolt P and nut E assembly returns to its initial opening position.
Pour réaliser une autre tentative de fermeture, il faudra d ' abord couper 1 ' a al i mentati on du verrou pendant 1 e temps nécessaire à la déchârge du condensateur Co, puis réalimenter le verrou.To carry out another attempt at closing, it will first be necessary to cut off the supply of the lock for the time necessary for the capacitor Co to discharge, then re-energize the lock.
Enfin, une borne de l'interrupteur de fin de course Il est sortie pour alimenter le voyant lumineux Vr qui restera allumé tant que le verrou n'est pas totalement fermé Finally, a terminal of the limit switch It is output to supply the indicator light Vr which will remain on until the lock is completely closed
