According to the invention the aim is achieved thanks to the fact that the second abrupt triggering mechanism comprises:
  • - a trigger lever, causing the release of the first abrupt trigger mechanism, which is held elastically armed by cooperation with a pawl subjected to the action of two drawers associated respectively with the detector devices, and which cooperates with a first surface of the transmission member for stopping the latter in the triggered position "D" when the cooperation of the pawl with the trigger lever is interrupted by the action of at least one drawer,
  • - a reset lever which is brought by the trigger lever and in a determined direction in the vicinity of a second surface of the transmission member, when the latter reaches this position and which cooperates elastically with this second surface to stop this member transmission in the open position, this second surface of this transmission member being capable of communicating to this disarming lever in the unstable resetting position a movement in the opposite direction which is transmitted on the one hand to the trigger lever to restore its cooperation with the ratchet, and on the other hand with the drawers towards the resettable detector devices.

Cette pièce mobile présente un premier bord 5 placé parallèlement à L, une première surface d'appui ou rampe inclinée 6 placée à un premier niveau 7, un second bord ou surface de butée 6 qui est parallèle à L, et une seconde rampe inclinée ou seconde surface d'appui 9 placée à un niveau 40.This moving part has a first edge 5 placed parallel to L, a first bearing surface or inclined ramp 6 placed at a first level 7, a second edge or abutment surface 6 which is parallel to L, and a second inclined ramp or second bearing surface 9 placed at a level 40.

Cette pièce mobile qui peut prendre l'une de quatre positions F, D, 0, R a été représentée en traits pleins dans la position F et seules les surfaces d'appui 6 et 9 ont été représentées en traits pointillés dans d'autres positions D et 0 respectivement D, 0 et R.This moving part which can take one of four positions F, D, 0, R has been shown in solid lines in position F and only the bearing surfaces 6 and 9 have been shown in dotted lines in other positions D and 0 respectively D, 0 and R.

Un levier de verrouillage 10 oscillant autour d'un premier pivot fixe 11 solidaire du boîtier est maintenu dans une position de repos, où il s'appuie sur une butée 12, sous l'action d'un couple CI de sens P fourni par un ressort 13. Ce levier porte un pivot mobile 14 autour duquel oscille un verrou éclipsable 15 dont la position de repos est déterminée par son appui, sur une butée 16 du levier, qui lui est fourni par le ressort 17. Ce verrou possède une extrémité 18 qui coopère avec la surface 6 pour maintenir la pièce mobile 3 dans la position F où le ressort 4 est armé. Par ailleurs une extrémité du levier de verrouillage 10 voisine du verrou porte un prolongement ou bec 19.A locking lever 10 oscillating around a first fixed pivot 11 secured to the housing is maintained in a rest position, where it rests on a stop 12, under the action of a torque CI of direction P provided by a spring 13. This lever carries a movable pivot 14 around which oscillates an eclipsable lock 15 whose rest position is determined by its support, on a stop 16 of the lever, which is provided to it by the spring 17. This lock has an end 18 which cooperates with the surface 6 to maintain the moving part 3 in the position F where the spring 4 is armed. Furthermore, one end of the locking lever 10 adjacent to the lock carries an extension or spout 19.

Un levier basculant de déclenchement 20 oscillant autour d'un pivot fixe 21 comporte un marteau 22 placé en regard du prolongement 19, un téton 23, un téton 24 et un téton 25.A tilting trigger lever 20 oscillating around a fixed pivot 21 comprises a hammer 22 placed opposite the extension 19, a stud 23, a stud 24 and a stud 25.

Une dent 26 est disposée è une extrémité de la pièce 20 qui est par ailleurs sollicitée par un couple C4 fourni par un ressort 27 et tendant è la déplacer dans le sens M.A tooth 26 is disposed at one end of the part 20 which is also stressed by a torque C4 supplied by a spring 27 and tending to move it in the direction M.

Ce levier de déclenchement 20 trouve une position de repos armée pour laquelle le ressort 27 est tendu lorsque la dent 26 s'appuie sur un bec 28 appartenant à un cliquet de déclenchement 29 qui peut osciller autour d'un pivot fixe 30 du boîtier et qui porte deux bras 31 et 32; ce cliquet de déclenchement possède une position de repos qui lui est communiquée par un ressort 34 et qui est définie par une butée 33 du boîtier.This trigger lever 20 finds an armed rest position for which the spring 27 is tensioned when the tooth 26 is supported on a spout 28 belonging to a trigger pawl 29 which can oscillate around a fixed pivot 30 of the housing and which carries two arms 31 and 32; this trigger pawl has a rest position which is communicated to it by a spring 34 and which is defined by a stop 33 of the housing.

Un levier de réarmement 35 oscillant librement autour d'un pivot 21' (qui peut être de même axe que celui du pivot 21 ou un pivot d'axe parallèle voisin) présente un premier bras 36, un second bras 37 et un troisième bras 38 dont une surface d'extrémité 39 se trouve placée au niveau 40, representé en pointillés, où se déplace la surface d'appui 9.A reset lever 35 oscillating freely around a pivot 21 ′ (which may be of the same axis as that of the pivot 21 or a pivot with a neighboring parallel axis) has a first arm 36, a second arm 37 and a third arm 38 an end surface 39 of which is placed at level 40, shown in dotted lines, where the bearing surface 9 moves.

Une extrémité 41 du bras 36 se trouve placée avec un certain jeu en regard d'un rebord 42 appartenant à un premier coulisseau 43, qui se déplace dans le boîtier par exemple de façon rectiligne, selon le sens E ou G et qui porte un doigt 44 placé en regard du bras 31 du cliquet 29.One end 41 of the arm 36 is placed with a certain clearance opposite a flange 42 belonging to a first slide 43, which moves in the housing for example in a straight line, in the direction E or G and which carries a finger 44 placed opposite the arm 31 of the pawl 29.

Une extrémité 45 du bras 37 se trouve placée également avec jeu au voisinage d'une surface d'extrémité 46 appartenant à un second coulisseau 47 qui se déplace dans le boîtier par exemple de façon rectiligne selon le sens H ou J et qui porte un doigt 48 placé en regard du bras 32 du cliquet 29.One end 45 of the arm 37 is also placed with clearance in the vicinity of an end surface 46 belonging to a second slide 47 which moves in the housing for example in a rectilinear fashion in the H or J direction and which carries a finger 48 placed opposite the arm 32 of the pawl 29.

Enfin, une surface 49 du levier de réarmement 35 éloignée du pivot 21' se trouve placée en regard du téton 25 de façon telle qu'une coopération angulaire puisse s'établir entre les leviers de réarmement et de déclenchement dans l'un des sens M ou N.Finally, a surface 49 of the reset lever 35 remote from the pivot 21 'is placed facing the stud 25 so that an angular cooperation can be established between the reset and trigger levers in one of the directions M or N.

Les pièces et organes 13, 10, 15 3, 4 appartiennent à un premier mécanisme à déclenchement brusque, et les pièces 20, 27, 29, 34, 35 appartiennent à un second mécanisme à déclenchement brusque.The parts and members 13, 10, 15 3, 4 belong to a first mechanism with sudden release, and the parts 20, 27, 29, 34, 35 belong to a second mechanism with sudden release.

Comme le dispositif qui vient d'être décrit a pour but d'opérer la mise en service ou l'arrêt d'un appareil contacteur à ouverture soit automatique en cas de défaut soit volontaire par voie extérieure manuelle grâce à un organe de commande locale, un interrupteur de contrôle 50 est place en série avec une bobine 51 d'un électro-aimant de contacteur placé dans le boîtier et représenté schématiquement en 54, et comprend par exemple un contact fixe 52 porté par le boîtier et un contact mobile 53, qui lui est associé; dans l'exemple représenté le contact mobile est porté par le levier de verrouillage 10 et l'interrupteur 50 est fermé lorsque, la pièce mobile 3 se trouvant dans la position F, ce levier de verrouillage est en position de repos contre la butée 12; les coulisseaux 43 ou 47 seront eux déplacés de façon brusque en sens E ou H, par des dispositifs ou organes détecteurs de surcharge réarmables placés dans le boîtier et représentés schématiquement par 55, 55', 56, 56' et 57, 57' pour répondre à l'apparition de surintensités te différents niveaux dans des circuits de charge 58 du contacteur 54; les repères 55', 56', 57' peuvent représenter respectivement des percuteurs et palettes magnétiques et des bilames.As the device which has just been described aims to operate the putting into service or stopping of a contactor device with opening either automatic in the event of a fault or voluntary by manual external route thanks to a local control member, a control switch 50 is placed in series with a coil 51 of a contactor electromagnet placed in the housing and shown diagrammatically at 54, and comprises for example a fixed contact 52 carried by the housing and a movable contact 53, which associated with it; in the example shown the movable contact is carried by the locking lever 10 and the switch 50 is closed when, the moving part 3 being in position F, this locking lever is in the rest position against the stop 12; the slides 43 or 47 will be moved abruptly in direction E or H, by resettable overload detector devices or bodies placed in the housing and represented schematically by 55, 55 ', 56, 56' and 57, 57 'to respond at the appearance of overcurrents te different levels in load circuits 58 of the contactor 54; the marks 55 ', 56', 57 'can respectively represent strikers and magnetic vanes and bimetallic strips.

Le fonctionnement du dispositif qui vient d'être décrit est le suivant.The operation of the device which has just been described is as follows.

Lorsque le cliquet de déclenchement 29 est déplacé dans le sens S, en raison de déplacements brusques effectués dans le sens E, ou dans le sens H, par l'un des coulisseaux 43 ou 47, la dent 26 du levier de déclenchement 20 est libérée et celui-ci pivote dans le sens M; au cours de ce mouvement brusque résultant de la détente du ressort 27, le téton 24 vient s'appuyer sur une surface de butée par exemple sur la surface de butée 8, pour donner à la pièce 20 une position de travail où le téton 23 se trouve placé au niveau 7 et en regard de la surface d'appui 6; ce même mouvement dû au couple C4 amène la percussion du bec 19 par le marteau 22 et par suite le basculement brusque de sens Q, du levier de verrouillage 10, ce dernier entraînant à son tour une rupture du contact mécanique entre la surface d'appui 6 et l'extrémité 18 du verrou 15.When the trigger 29 is moved in the S direction, due to sudden movements made in the E direction, or in the H direction, by one of the slides 43 or 47, the tooth 26 of the trigger lever 20 is released and it pivots in the sense M; during this sudden movement resulting from the relaxation of the spring 27, the stud 24 comes to bear on a stop surface for example on the stop surface 8, to give the part 20 a working position where the stud 23 located at level 7 and facing the bearing surface 6; this same movement due to the torque C 4 brings the percussion of the spout 19 by the hammer 22 and consequently the sudden tilting of direction Q, of the locking lever 10, the latter in turn causing a break in the mechanical contact between the surface of support 6 and the end 18 of the latch 15.

La pièce mobile 3 qui est ainsi libérée à son tour se déplace alors dans le sens L jusqu'au moment où la surface d'appui 6 entre en contact avec le téton 23. La pièce mobile 3 occupe alors une position stable D dite de déclenchement où l'interrupteur 50 est ouvert; cette ouverture est due au fait que l'extrémité 18 du verrou 15,5' est appliquée contre le bord 5 lorsque le levier basculant 10 a pris brusquement une position de travail qui le sépare de la butée 12.The moving part 3 which is thus released in its turn then moves in the direction L until the bearing surface 6 comes into contact with the stud 23. The moving part 3 then occupies a stable position D called the trigger where the switch 50 is open; this opening is due to the fact that the end 18 of the latch 15.5 ′ is applied against the edge 5 when the rocking lever 10 has suddenly taken up a working position which separates it from the stop 12.

Dans cette position le téton 25 s'est appliqué contre la surface 49 du levier d'armement 35 et a déplacé celui-ci de façon telle que la surface d'extrémité 39 soit placée au voisinage de la surface d'appui 9 de l'organe de transmission 3.In this position, the stud 25 is applied against the surface 49 of the cocking lever 35 and has moved the latter so that the end surface 39 is placed in the vicinity of the bearing surface 9 of the transmission unit 3.

Une manoeuvre exercée sur la pièce 3 dans le sens K en vue de mettre l'appareil en service c'est-à-dire en position F ne peut être suivie d'effet, car le levier de déclenchement 20, ayant échappé au cliquet 29, occupe une position qui empêche le levier de verrouillage 10 de reprendre sa position de repos, de refermer l'interrupteur 50, et de placer l'extrémité 18 du verrou 15 contre la surface d'appui 6.An operation exerted on the part 3 in the direction K in order to put the apparatus into service, that is to say in position F cannot be followed by effect, since the trigger lever 20, having escaped the pawl 29 , occupies a position which prevents the locking lever 10 from resuming its rest position, closing the switch 50, and placing the end 18 of the lock 15 against the bearing surface 6.

L'appareil peut par contre être mis volontairement en position d'ouverture permanente "0" grâce à une action extérieure exercée sur l'organe 2 dans le sens "L", qui provoque d'abord un léger basculement du levier de déclenchement 20 dans le sens "N" grâce à l'action de la surface d'appui 6 contre le téton 23; ce basculement, qui permet au téton 23 d'échapper à la surface de butée 6, et de venir s'appuyer sur la surface 5 amène la surface d'appui 9 à coopérer avec la surface 39 du bras 38 du levier de réarmement 35 pour fournir une position "O", stable, d'ouverture qui résulte de l'équilibre de forces antagonistes exercées par les ressorts 27 et 4 et transmises par les pièces 27, 20, 25, 49, 35, 38, 39 d'une part et par les pièces 4,3,9 d'autre part.On the other hand, the device can be put voluntarily in the permanent open position "0" thanks to an external action exerted on the member 2 in the "L" direction, which first causes a slight tilting of the trigger lever 20 in the direction "N" thanks to the action of the bearing surface 6 against the stud 23; this tilting, which allows the stud 23 to escape the abutment surface 6, and to come to bear on the surface 5 causes the bearing surface 9 to cooperate with the surface 39 of the arm 38 of the reset lever 35 for provide a stable, open "O" position which results from the balance of opposing forces exerted by the springs 27 and 4 and transmitted by the parts 27, 20, 25, 49, 35, 38, 39 on the one hand and by the parts 4,3,9 on the other hand.

Le réarmement des dispositifs de déclenchement de l'appareil après un déclenchement automatique doit avoir pour effet d'une part de replacer l'organe de transmission en position F et d'autre part de remettre les dispositifs 55, 56, 57, 43 et 47 dans un état correspondant à l'absence de défaut. Ce réarmement, qui fournira des mouvements de sens "G" respectivement "J", aux coulisseaux 43, 47, et sera transmis par des moyens schématisés en 59,60,61, résultera de la cooperation entre la surface d'appui 9 (ou une arête 62 séparant cette surface de la surface d'appui 8) contre l'extrémité 39, du levier d'armement 35.Resetting the device's triggering devices after an automatic triggering must have the effect of, on the one hand, returning the transmission member to position F and, on the other hand, resetting the devices 55, 56, 57, 43 and 47 in a state corresponding to the absence of fault. This rearming, which will provide movements of direction "G" respectively "J", to the slides 43, 47, and will be transmitted by means shown diagrammatically in 59, 60, 61, will result from the cooperation between the bearing surface 9 (or an edge 62 separating this surface from the bearing surface 8) against the end 39 of the cocking lever 35.

Ce réarmement est opéré au cours d'un déplacement de l'organe de transmission 3 commande par une action exterieure sur l'organe 2 et dans le sens "L", à partir de la position "D" ou "0" vers la position "R"; la surface 9 repousse alors le bras de levier 38, et provoque d'une part un pivotement de la pièce 35 dans le sens "N" et celui du levier 20 jusqu'au moment ou le bec du cliquet 29 peut se glisser derrière la dent 26, et d'autre part un entraînement de sens G et J des coulisseaux 43,47 par les extrémités 41 respectivement 45 des bras 36 respectivement 37. La position "R" ainsi obtenue n'est pas stable en raison de l'action élastique antagoniste transmise du ressort 27 à l'organe de transmission 3 par les leviers 20 et 35, de sorte que lorsque cesse l'action exterieure, cet organe 3 tend à revenir en position "0".This rearming is carried out during a movement of the transmission member 3 commanded by an external action on member 2 and in the "L" direction, from the "D" or "0" position to the position "R"; the surface 9 then pushes the lever arm 38, and on the one hand causes the part 35 to pivot in the "N" direction and that of the lever 20 until the ratchet beak 29 can slide behind the tooth 26, and on the other hand a direction drive G and J of the slides 43,47 by the ends 41 respectively 45 of the arms 36 respectively 37. The position "R" thus obtained is not stable due to the elastic action antagonist transmitted from the spring 27 to the transmission member 3 by the levers 20 and 35, so that when the external action ceases, this member 3 tends to return to position "0".

Dans un mode de réalisation représenté à la figure 2, où les pièces ayant les mêmes fonctions que dans l'exemple précédent portent les mêmes références, les deux pivots 21,21' précédents ont des axes confondus en 21, et les surfaces d'appui 6' et 9' sont des portions de surfaces voisines appartenant à une même surface. L'appareil est ici représenté en position de fermeture "F".In an embodiment represented in FIG. 2, where the parts having the same functions as in the previous example bear the same references, the two preceding pivots 21, 21 ′ have axes coinciding at 21, and the bearing surfaces 6 'and 9' are portions of neighboring surfaces belonging to the same surface. The device is shown here in the closed position "F".

Un levier de déclenchement 20', dont la surface 24' vient coopérer ici avec une butée 8' du boîtier 1 pour faciliter la lecture du dessin, pourrait également trouver une position de travail par appui contre une surface de butée 8" analogue à la surface de butée S de la figure 1.A trigger lever 20 ', the surface 24' of which here cooperates with a stop 8 'of the housing 1 to facilitate reading of the drawing, could also find a working position by pressing against a stop surface 8 "similar to the surface of stop S in FIG. 1.

Dans la position de travail du levier de déclenchement 20', le rebord 23' de ce levier est rencontré soit par la surface d'appui 6' soit par une arête 62' qui la sépare de la surface 5, pour conférer à l'organe de transmission 3, et donc à l'organe de commande locale 2 qui lui est relié, une position stable déclenchée "D", voir figure 3a.In the working position of the trigger lever 20 ', the flange 23' of this lever is encountered either by the bearing surface 6 'or by an edge 62' which separates it from the surface 5, to give the member transmission 3, and therefore to the local control member 2 which is connected to it, a stable position triggered "D", see FIG. 3a.

Le levier de verrouillage pivotant 10, (voir figure 2) porte un levier de contact 63 qui est appliqué contre une butée 64 de ce levier par un ressort 65 pour avoir une position de repos. Ce levier de contact possède une extrémité 66 qui peut soulever un contact mobile 53' pour le séparer d'un contact fixe 52' appartenant à un interrupteur de contrôle 50' ayant la même fonction que l'interrupteur 50 précédent.The pivoting locking lever 10 (see Figure 2) carries a contact lever 63 which is applied against a stop 64 of this lever by a spring 65 to have a rest position. This contact lever has an end 66 which can lift a movable contact 53 'to separate it from a fixed contact 52' belonging to a control switch 50 'having the same function as the previous switch 50.

L'ouverture de cet interrupteur résulte ici soit du basculement du levier 10 dans le sens Q après libération par le levier de déclenchement, soit encore lorsque, le levier 10 étant basculé ou non, l'extrémité 66 est repoussée dans le sens "K" grâce à une action T définie ultérieurement.The opening of this switch results here either from the tilting of the lever 10 in the Q direction after release by the trigger lever, or even when, the lever 10 being tilted or not, the end 66 is pushed back in the "K" direction thanks to a T action defined later.

Le caractère brusque de l'ouverture de l'interrupteur 50' résulte soit du basculement instantané qui est communiqué au levier 10 par le levier de déclenchement, soit de la séparation instantanée du verrou 15, 18 et de la surface d'appui 6' lorsque l'organe de transmission 3' est déplacé par l'organe de commande locale 2 vers la position "0".The abrupt nature of the opening of the switch 50 'results either from the instantaneous tilting which is communicated to the lever 10 by the tripping lever, either of the instantaneous separation of the bolt 15, 18 and of the bearing surface 6 'when the transmission member 3' is moved by the local control member 2 to the "0" position.

Dans le premier cas un couple antagoniste 4 de sens M est communiqué au levier 10 par le ressort 27 contre un couple C1 de sens P communique par le ressort 13.In the first case, an opposing torque 4 of direction M is communicated to the lever 10 by the spring 27 against a couple C1 of direction P communicates by the spring 13.

Dans le second cas un effort extérieur communiqué aux organes 2 et 3' s'ajoute à l'effort du ressort de rappel 4 pour faire d'abord basculer le verrou éclipsable 15 dans le sens "Q" contre un couple C2 qui lui est donné par le ressort 17; lorsqu'un couple C3 supérieur au couple C1 est transmis au levier 10, il se produit en raison du fait que le verrou éclipsable a pris une position inclinée par rapport à la surface 6', un basculement très rapide du levier 10 dans le sens Q, qui permet au verrou 18 de glisser le long de l'arête 62' et de se placer contre la surface de butée 5 pour maintenir l'interrupteur 50' ouvert.In the second case, an external force communicated to the members 2 and 3 ′ is added to the force of the return spring 4 in order to first tilt the eclipsable lock 15 in the "Q" direction against a torque C2 which is given to it. by spring 17; when a torque C3 greater than the torque C1 is transmitted to the lever 10, it occurs due to the fact that the eclipsable lock has taken an inclined position relative to the surface 6 ', very rapid tilting of the lever 10 in the direction Q , which allows the latch 18 to slide along the edge 62 'and to be placed against the abutment surface 5 to keep the switch 50' open.

Comme dans le cas de la figure 1, les positions D, 0 mettent en oeuvre une cooperation antagoniste entre les surfaces 6', 23' et respectivement 9', 39' pour conférer deux positions stables à l'organe de transmission et à l'organe de commande locale, voir figures 3a et 3b ou les fleches opposees indiquent ces coopérations.As in the case of FIG. 1, the positions D, 0 implement an antagonistic cooperation between the surfaces 6 ′, 23 ′ and respectively 9 ′, 39 ′ to give two stable positions to the transmission member and to the local control member, see Figures 3a and 3b where the opposite arrows indicate these cooperations.

La position instable "R" est ici encore obtenue par un effort de rappel vers la position "0" qui est communiqué à l'organe de transmission 3' par le ressort 27 dont l'action est transmise par le levier de déclenchement 20', un bras 25' de ce dernier, la surface 49, le levier 35' et l'extrémité 39', cette dernière agissant sur la surface 9', voir figure 3c, où les flèches opposées indiquent des actions antagonistes.The unstable position "R" is here again obtained by a return effort towards the position "0" which is communicated to the transmission member 3 'by the spring 27 whose action is transmitted by the trigger lever 20', an arm 25 'of the latter, the surface 49, the lever 35' and the end 39 ', the latter acting on the surface 9', see FIG. 3c, where the opposite arrows indicate antagonistic actions.

Dans les deux modes de réalisation illustrés les déplacements de l'organe de transmission ont été supposés rectilignes; les dispositifs sont aptes à fonctionner de la même manière lorsque ces pièces 3, 3' sont des pièces tournantes, par exemple solidaires d'un bouton rotatif 2 mobile autour d'un axe YY' perpendiculaire à des déplacements tangentiels K et L.In the two embodiments illustrated, the movements of the transmission member have been assumed to be rectilinear; the devices are able to operate in the same way when these parts 3, 3 'are rotating parts, for example integral with a rotary button 2 movable around an axis YY' perpendicular to tangential displacements K and L.

Dans un mode de réalisation représenté en position déclenchée "D" à la figure 4a, et où les mêmes repères signalent les mêmes fonctions, la pièce 3" tournante, qui reprend les mêmes fonctions que la pièce 3' précédente, est mobile autour d'un pivot 68 dont l'axe est parallèle aux axes des pivots parallèles 11, 67,14, 21 et 30.In an embodiment shown in the triggered position "D" in FIG. 4a, and where the same references indicate the same functions, the rotating part 3 ", which takes up the same functions as the previous part 3 ', is movable around a pivot 68 whose axis is parallel to the axes of the parallel pivots 11, 67, 14, 21 and 30.

Le levier de contact 63 comporte outre une première extrémité 66' dont la fonction sera précisée ultérieurement, une seconde extrémité isolante 69 qui coopère avec le contact mobile 53' comme le faisait précédemment l'extrémité 66.The contact lever 63 further comprises a first end 66 'whose function will be specified later, a second insulating end 69 which cooperates with the movable contact 53' as the end 66 did previously.

Pour des raisons constructives le levier de réarmement 35' représenté en pointillés comporte à la place des bras 41, 45 des tétons 41', 45' ayant, pour effectuer le réarmement, les mêmes fonctions que les bras 41 et 45 et ce par coopération avec les surfaces 42 et respectivement 46.For constructive reasons, the reset lever 35 ′ shown in dotted lines comprises, instead of the arms 41, 45, pins 41 ′, 45 ′ having, for resetting, the same functions as the arms 41 and 45 and this by cooperation with surfaces 42 and 46 respectively.

Les surfaces 6' et 9' visibles à la figure 6 sont alignées mais decalées axialement le long de la pièce de transmission tournante 3" qui comporte de plus une surface cylindrique 8" qui sert de butée à la surface 24. Un dégagement 87 de la pièce 3" (voir figure 4), permet au bras 38 de ne pas entrer en contact avec cette pièce 3" en un autre endroit que 9'. Le levier de déclenchement 20" présente un bras 25' qui coopère avec un téton 49' du levier de réarmement, dont la fonction est la même que celle de la surface 49 précédente. Les propriétés et modes de fonctionnement des variantes sont sensiblement identiques à ceux de l'appareil selon la figure 1.The surfaces 6 ′ and 9 ′ visible in FIG. 6 are aligned but offset axially along the rotating transmission part 3 "which also has a cylindrical surface 8" which serves as a stop for the surface 24. A clearance 87 from the part 3 "(see FIG. 4), allows the arm 38 not to come into contact with this part 3" in a place other than 9 '. The trigger lever 20 "has an arm 25 'which cooperates with a stud 49' of the reset lever, the function of which is the same as that of the preceding surface 49. The properties and operating modes of the variants are substantially identical to those of the device according to figure 1.

Des mécanismes de déclenchement tels que ceux répresentes aux figures 2 à 6 sont particulièrement adaptés à une commande à distance en recevant des actions de commande extérieures; celles-ci sont fournies par exemple par un actionneur électrique, faisant appel à un petit moteur synchrone, destinées à opérer la fermeture de l'appareil; en vue d'opérer à distance le réarmement et la mise en service.Triggering mechanisms such as those shown in Figures 2 to 6 are particularly suitable for remote control by receiving external control actions; these are provided for example by an electric actuator, using a small synchronous motor, intended to operate the closing of the device; in order to remotely reset and put into service.

Les découplages opérés par ces mécanismes entre les fonctions de réarmement, de déclenchement et de fermeture de l'interrupteur de contrôle, ainsi que d'une part les dispositions respectives des sens de déplacement des pièces qui effectuent ces fonctions et que d'autre part, les dispositions respectives entre les positions "F, D, 0 et R" permettent de réaliser de façon simple une télécommande de l'appareil comportant ce mécanisme pour le réarmer à distance après une ouverture automatique.The decoupling operated by these mechanisms between the reset, trip and close functions of the control switch, as well as on the one hand the respective arrangements of the directions of movement of the parts which perform these functions and, on the other hand, the respective arrangements between the positions "F, D, 0 and R" allow a simple remote control of the device comprising this mechanism to be reset remotely after an automatic opening.

On observera en effet que dans les mécanismes décrits aux figures 2, 3, 4 et 6, le déplacement de sens "K" fourni à l'organe de transmission pour l'amener en position F, le déplacement des bras 36 des leviers de réarmement fourni pour opérer lors d'un réarmement, ainsi que le déplacement que l'on doit appliquer à l'extrémité 66' du levier de contact 63 pour maintenir l'interrupteur ouvert, sont parallèles et de même sens.It will be observed in fact that in the mechanisms described in FIGS. 2, 3, 4 and 6, the displacement of direction "K" supplied to the transmission member to bring it into position F, the displacement of the arms 36 of the reset levers supplied to operate during a reset, as well as the displacement which must be applied to the end 66 'of the contact lever 63 to keep the switch open, are parallel and in the same direction.

Il est donc possible d'associer à ces mécanismes, (voir figure 5, où pour la clarté du dessin ni le levier de déclenchement ni le cliquet n'ont été représentés) un coulisseau interne de télécommande 70 présentant trois portions 71, 72, 73 propres à exercer des poussées de même sens (indiquées par les flèches S, T, V) par exemple sur une portion de surface 74 de l'organe de transmission 3' qui serait placée de préférence à un troisième niveau 75 au voisinage des niveaux 7 et 40, sur l'extrémité 66' et sur le bras 36.It is therefore possible to associate with these mechanisms, (see FIG. 5, where for clarity of the drawing neither the trigger lever nor the pawl have been shown) an internal remote control slide 70 having three portions 71, 72, 73 suitable for exerting thrusts in the same direction (indicated by arrows S, T, V) for example on a surface portion 74 of the transmission member 3 'which would preferably be placed at a third level 75 in the vicinity of levels 7 and 40, on the end 66 'and on the arm 36.

Ce coulisseau 70 qui est associé à un ressort de rappel 77 et à une butée 76 du boîtier pour fixer sa position de repos W est représenté dans la position Z qu'il occupe au moment où vient de s'effectuer l'accrochage en position "F" de l'organe de transmission 3', par le verrou 15, 18.This slide 70 which is associated with a return spring 77 and with a stop 76 of the housing to fix its rest position W is shown in the position Z which it occupies at the time when the hooking in position has just been carried out. F "of the transmission member 3 ', by the latch 15, 18.

Un sous-ensemble 78 fixé de façon amovible sur le boîtier 1, et comportant deux bornes d'alimentation 79, 80, entre lesquelles sont branchés un petit moteur unidirectionnel 81 synchrone par exemple et un interrupteur de maintien 82, présente un poussoir 83 qui est actionné par le moteur grâce à un réducteur 85 ayant une grande démultiplication et à une came 90. Ce poussoir 83 pénètre dans le boîtier 1 à travers une ouverture 88 de celui-ci pour coopérer avec la surface de poussée 87 du coulisseau 70 après avoir traversé une ouverture 89 du boîtier 1.A subassembly 78 removably attached to the housing 1, and comprising two supply terminals 79, 80, between which are connected a small synchronous unidirectional motor 81 for example and a holding switch 82, has a pusher 83 which is actuated by the motor thanks to a reduction gear 85 having a large gear reduction and to a cam 90. This pusher 83 enters the housing 1 to through an opening 88 thereof to cooperate with the thrust surface 87 of the slider 70 after having passed through an opening 89 of the housing 1.

L'interrupteur 82 qui est uniquement ouvert lorsque le poussoir 83 est en position de repos W, et se ferme dès que celui-ci se déplace dans le sens K, assure la continuité de l'alimentation du moteur lorsque disparait une courte tension de mise en route appliqué directement au moteur à l'aide d'un interrupteur 91 entre la borne 79 et une troisième borne 84; cette tension étant appliquée au moment où doit s'effectuer le réarmement à distance.The switch 82 which is only open when the pusher 83 is in the rest position W, and closes as soon as it moves in the direction K, ensures the continuity of the power supply to the motor when a short setting voltage disappears. en route applied directly to the engine using a switch 91 between terminal 79 and a third terminal 84; this voltage being applied when the remote reset is to be carried out.

Le poussoir 83 qui est associé à un ressort 86 et qui effectue une fois pour chaque ordre un seul déplacement aller de sens "K" et retour de sens "L" s'étendant entre des positions successives W, B, X, B, W communique donc au coulisseau 70 des déplacements d'amplitude WX.The pusher 83 which is associated with a spring 86 and which performs once for each order a single forward movement of direction "K" and return of direction "L" extending between successive positions W, B, X, B, W therefore communicates to slide 70 displacements of amplitude WX.

La position de repos W du coulisseau qui correspond à celle du poussoir 70 est telle que, même pour une position de réarmement "R" donnée à l'organe de transmission 3' par une action extérieure manuelle exercée sur l'organe de commande locale 2, la surface d'appui 74 ne puisse venir en contact avec la portion 71; de même ni le bras 36 ni le bras 66' ne peuvent venir contre les portions 73 respectivement 72 pour la position "D" de l'organe de transmission.The rest position W of the slide which corresponds to that of pusher 70 is such that, even for a reset position "R" given to the transmission member 3 'by a manual external action exerted on the local control member 2 , the bearing surface 74 cannot come into contact with the portion 71; likewise neither the arm 36 nor the arm 66 'can come against the portions 73 respectively 72 for the position "D" of the transmission member.

La position maximum X atteinte par le coulisseau et donnée à l'organe de transmission 3' est telle que la surface d'appui 6' se trouve placée légèrement à gauche du verrou 18 pour permettre sa mise en place sous l'effet du ressort 13.The maximum position X reached by the slide and given to the transmission member 3 'is such that the bearing surface 6' is placed slightly to the left of the latch 18 to allow it to be put in place under the effect of the spring 13 .

Dans toutes les positions du coulisseau 70 situées à gauche d'une position B, la portion 72 rencontre l'extrémité 66' du levier de contact et maintient ouvert l'interrupteur 50'; si la tentative de réarmement, communiquée pendant la course allant de W vers X au levier de déclenchement 35', est effectivement suivie d'un accrochage du levier de déclenchement par le cliquet 29 pendant la course de retour allant de W vers B en passant par Z, le levier 10 peut prendre la position représentée sur la figure 5 et l'interrupteur 50' ne peut se refermer que lorsque le coulisseau revient à droite de la position B. Toutefois l'accrochage du levier de déclenchement 20' par le cliquet 29 pouvant en effet uniquement se réaliser si aucun déplacement de direction H n'est donné au coulisseau 47 par le mécanisme à déclenchement brusque 57 (répondant lui-même à une bilame 57' chauffée ou encore chaude), ce levier 20" viendrait de nouveau basculer le levier 10 avant que le point B soit atteint, si ce coulisseau 47 ne pouvait reprendre une position dirigée vers J.In all the positions of the slide 70 located to the left of a position B, the portion 72 meets the end 66 'of the contact lever and keeps the switch 50' open; if the reset attempt, communicated during the race going from W to X to the trigger lever 35 ', is effectively followed by a hooking of the trigger lever by the pawl 29 during the return race going from W to B passing through Z, the lever 10 can take the position shown in FIG. 5 and the switch 50 ′ can only close when the slide returns to the right of position B. However, the catching of the trigger lever 20 ′ by the pawl 29 can indeed only be achieved if no displacement of direction H is given to the slide 47 by the abrupt release mechanism 57 (itself responding to a bimetallic strip 57 'heated or still hot), this lever 20 "would again rock lever 10 before point B is reached, if this slide 47 could not resume a position directed towards J.

Les résultats obtenus au cours du fonctionnement télécommandé du dispositif qui vient d'être décrit sont donc comparables à ceux qui sont obtenus par une action manuelle de réarmement et de fermeture exercée sur l'organe de commande locale.The results obtained during the remote-controlled operation of the device which has just been described are therefore comparable to those obtained by a manual reset and closing action exerted on the local control member.

Dans un mode de réalisation selon la figure 4b utilisant un organe de transmission 3" tel que celui de la figure 6 une surface 74' qui a la même fonction que la surface 74 de la figure 5, peut se trouver alignée avec les surfaces 6' et 9' tout en étant décalées axialement pour ne pas interférer avec les surfaces 24 et 39, voir figure 6.In an embodiment according to FIG. 4 b using a 3 "transmission member such as that of FIG. 6, a surface 74 ′ which has the same function as the surface 74 of FIG. 5, can be aligned with the surfaces 6 'and 9' while being axially offset so as not to interfere with surfaces 24 and 39, see Figure 6.

La mise en oeuvre d'un coulisseau tel que 70 dans le mode de réalisation selon la figure 4a peut être avantageusement effectuée en raison du fait que les pièces ou surfaces 66', 74' et 41' qui sont toutes situées au dessous de l'axe 68' se déplacent dans le même sens K au moment où s'effectue le réarmement (voir figure 4b où les organes représentés se trouvent dans un état comparable à célui de la figure 5).The implementation of a slide such as 70 in the embodiment according to Figure 4a can be advantageously carried out due to the fact that the parts or surfaces 66 ', 74' and 41 'which are all located below the axis 68 ′ move in the same direction K at the time when the rearming is carried out (see FIG. 4b where the members represented are in a state comparable to that of FIG. 5).

Au cours des divers processus de réarmement, l'engagement du cliquet derrière la dent ne doit pouvoir s'effectuer que si les circonstances ou défauts qui ont provoqué un déclenchemment en position D ont disparu. Comme le contacteur a été ouvert, et que, par suite, aucun courant ne circule dans le circuit de charge, la seule circonstance pouvant interdire l'engagement du cliquet est celle qui résulte de la déflexion d'un bilame 57' encore chauffé à la suite d'une surcharge prolongée; dans cette situation l'action qui est provoquée par un détecteur de surcharge 57 et qui est transmise en permanence pendant le temps de refroidissement du bilame par la voie 61, empêche le coulisseau 47 de conserver une position dirigée vers J et empêche donc le clinquet de prendre sa position de repos; par suite, le levier de déclenchement 20 respectivement 20', 20", ne peut prendre sa position armée lorsque l'organe de transmission quitte la position R pour se diriger vers les positions successives 0 et F. En raison de cette impossibilité, le levier de verrouillage 10 ne peut donc prendre sa position de repos, de sorte que l'interrupteur 50 reste ouvert, même si l'on amène la pièce 3 en position F; par suite, une refermeture du circuit de charge 58 ne peut être effectuée tant qu'un bilame est encore chaud.During the various rearming processes, the engagement of the pawl behind the tooth should only be possible if the circumstances or faults which caused a triggering in position D have disappeared. As the contactor has been opened, and as a result, no current is flowing in the charging circuit, the only circumstance which may prevent the engagement of the pawl is that which results from the deflection of a bimetallic strip 57 'still heated to the following prolonged overload; in this situation the action which is caused by an overload detector 57 and which is continuously transmitted during the cooling time of the bimetallic strip by the channel 61, prevents the slide 47 from retaining a position directed towards J and therefore prevents the latch from take its rest position; as a result, the trigger lever 20 respectively 20 ', 20 ", cannot take its armed position when the transmission member leaves the position R to move towards the successive positions 0 and F. Because of this impossibility, the lever locking device 10 cannot therefore take its rest position, so that the switch 50 remains open, even if the part 3 is brought into position F; consequently, reclosing of the charging circuit 58 cannot be effected as long that a bimetallic strip is still hot.

Si le défaut qui a provoqué l'ouverture du contacteur, et donc la mise en position D de l'organe de transmission, résulte de façon instantanée d'un court-circuit franc ou d'un court-circuit impédant (qui ne donnent pas au bilame de temps de s'échauffer), un mouvement de réarmement allant de D vers R, permet d'effectuer la mise en position armée du levier de déclenchement 20 ou 20' ou 20" car aucune action permanente issue des détecteurs soit magnétiques 55 soit thermiques 56 n'est transmise par les voies 59 ou respectivement 60 au tiroir correspondant 43 ou 47.If the fault which caused the opening of the contactor, and therefore the setting in position D of the transmission member, results instantaneously from a frank short-circuit or an impedant short-circuit (which do not give at the bimetal of time to heat up), a rearming movement going from D to R, allows to carry out the armed position of the trigger lever 20 or 20 'or 20 "because no permanent action from the detectors is magnetic 55 either thermal 56 is transmitted via channels 59 or respectively 60 to the corresponding drawer 43 or 47.

Une tentative de mise en service de l'appareil, effectuée par un déplacement de l'organe de transmission, allant de R jusqu'à F provoque par suite, le basculement du levier de verrouillage 10 lorsque cet organe atteint la position F, car le marteau 22 du levier 20 a repris une position écartée du bec 19. Si le court-circuit est toujours présent, la fermeture de l'interrupteur de contrôle 50 ou 50' qui permet donc une excitation du contacteur 54, provoquera une excitation d'au moins un des organes détecteurs 55 ou 56 et par suite les déclenchements successifs des leviers 20, 20', 20" et 10, ainsi que la réouverture de l'interrupteur 50 ou 50' de sorte que le circuit de charge s'ouvrira de nouveau par desexcitation de l'électro-aimant 51.An attempt to commission the device, carried out by a displacement of the transmission, going from R to F consequently causes the tilting of the locking lever 10 when this member reaches the position F, because the hammer 22 of the lever 20 has taken up a position away from the spout 19. If the short circuit is always present, the closing of the control switch 50 or 50 'which therefore allows excitation of the contactor 54, will cause an excitation of at least one of the detector members 55 or 56 and consequently the successive actuations of the levers 20, 20' , 20 "and 10, as well as the reopening of the switch 50 or 50 'so that the charging circuit will open again by de-energizing the electromagnet 51.

Ce fonctionnement est établi même si l'organe de transmission 3 ou 3' est maintenu en position F par une action extérieure manuelle ou non.This operation is established even if the transmission member 3 or 3 'is maintained in position F by manual or non-manual external action.
