This pole shaft 2, at one of its ends, is intended to be driven by the device control device, while its opposite end comprises a so-called first wheel 3 integral with said shaft and intended to cooperate with the motor device M, this shaft being further mechanically connected between these two ends, to the aforementioned closing spring 1.
This so-called first wheel 3 is intended to be rotated by a pinion said first 4 belonging to the motorization device M by means of an intermediate device 5. This intermediate device 5 comprises a so-called secondary wheel 6 and a so-called secondary gear 7 , this secondary wheel 6 being intended to be driven by the motorization device M, while the so-called secondary gear 7 cooperates with the so-called first wheel 3, so that in the engaged position, the motorization device M rotates the so-called first wheel 3 and therefore the control shaft 2 through the so-called second wheel 6 and said second pinion 7. According to the invention, said first wheel 3 comprises an annular sector 8 intended to cooperate with a disengagement cone 9 provided on said second wheel 6.
According to the illustrated realization on the Figures 4 to 9 the so-called second wheel 6 is mechanically connected to its associated first said pinion 7 by means of a clutch device 10 allowing said wheel to be displaced relative to its associated pinion, which, when moving, disengages itself from this ci, thus interrupting the mechanical connection between the so-called first wheel 3 and the pinion said first 4. This clutch device 10 comprises in a manner known per se a drive tooth in a clutch sleeve with claws.
According to another illustrated embodiment on the Figures 12 and 13 the so-called second wheel 6 and the second said pinion 7 form a unitary assembly and capable of sliding axially between a first position in which the so-called second wheel 6 of the intermediate device 5 is engaged with the pinion said first 4 of the motorization device M and a second position in which these two elements are disengaged with respect to each other.
According to a particular embodiment of the invention, the length of the angular sector 8 corresponds to the closing stroke of the control device.

Le fonctionnement du dispositif de débrayage selon les deux réalisations illustrées va être décrit dans ce qui suit en référence aux figures 4 à 13.The operation of the disengaging device according to the two embodiments illustrated will be described in the following with reference to the Figures 4 to 13 .

Sur les figures 4,5 et 6, le dispositif est en fin d'armement du ressort de fermeture.On the figures 4,5 and 6 , the device is at the end of arming the closing spring.

Dans cette position, le secteur annulaire 8 de la roue dite première 3 commence à venir en engagement avec le cône de débrayage 9 prévu sur la roue dite seconde 6. Cela entraîne le déplacement relatif axial entre les deux roues 3,6, la roue dite seconde 6 se déplaçant par rapport à l'axe du crabot de manière que les roues dites première et seconde s'éloignent l'une de l'autre. Ce déplacement de la roue dite seconde 6 entraîne le désengagement de cette roue du pignon dit premier 4 du dispositif de motorisation, ce qui interrompt la liaison mécanique entre le dispositif de motorisation M et la roue dite première 3 d'entraînement de l'arbre des pôles.In this position, the annular sector 8 of the so-called first wheel 3 begins to come into engagement with the disengagement cone 9 provided on the so-called second wheel 6. This causes the axial relative displacement between the two wheels 3.6, the so-called wheel second 6 moving relative to the axis of the clutch so that said first and second wheels away from each other. This displacement of the so-called second wheel 6 causes the disengagement of this wheel of said first pinion 4 of the drive device, which interrupts the mechanical connection between the drive device M and the so-called first drive wheel 3 of the drive shaft. poles.

Sur les figures 7 à 9, le dispositif de commande est en cours de fermeture, la roue dite première 3 s'étant déplacée dans le sens des aiguilles d'une montre. Pendant ce mouvement, la position débrayée est maintenue pendant toute la durée de la fermeture par le fait que le secteur annulaire 8 de la première roue 3 coopère avec le cône de débrayage 9 pendant toute cette durée, la longueur du secteur annulaire 8 correspondant sensiblement à la longueur de la course de fermeture.
Sur les figures 10 et 11, le dispositif de commande est en position fermée désarmée. Pour arriver à cette position, la roue dite première 3 s'est déplacée en rotation dans le sens des aiguilles d'une montre. Le secteur annulaire 8 a quitté le cône de débrayage 9 entraînant le rapprochement des deux roues 3,6 l'une par rapport à l'autre, par l'intermédiaire d'un ressort 13 placé entre le châssis et la roue dite seconde et apte à rappeler la roue dite seconde 6 vers la roue dite première 3. Ce déplacement de la roue dite seconde 6 sous l'effet du ressort, entraîne la solidarisation en rotation de la roue dite seconde 6 avec le pignon dit premier 7, ceci rétablissant la liaison mécanique entre le dispositif de motorisation M et l'arbre de commande 2, de manière à permettre le réarmement du ressort de fermeture 1 par l'entraînement de l'arbre de commande 2 au moyen du dispositif de motorisation M.
La figure 14 illustre l'utilisation selon une réalisation particulière, d'un micro-contact 11 pour réaliser l'alimentation du moteur électrique M du réducteur, en fonction de la position du dispositif de commande.
Ce micro-contact 11 comporte une palette 12 apte à coopérer avec une protubérance 14 formant came appartenant à une roue 2a solidaire de l'arbre de commande 2.
A cet effet, la roue 2a comporte sur un peu moins de la moitié de sa circonférence, un évidement semi-circulaire, la protubérance précitée 14 étant formée par la partie de la circonférence de la roue 2a complémentaire à celle comportant l'évidement.
Sur la figure 15, le dispositif de commande est position ouverte armée, ou bien fermée armée. Dans cette position, la palette 12 du micro-contact 11 est en position haute, car la palette 12 se trouve dans l'évidement, ce qui implique que le micro-contact 11 n'est pas actionné et en conséquence, que le moteur électrique M n'est pas alimenté.
Sur la figure 16, l'arbre de commande 2 et sa roue associée 2a se sont déplacés en rotation d'un angle d'environ 180° dans le sens inverse des aiguilles d'une montre, afin d'amener le dispositif de commande en position fermée désarmée.
Pendant cette rotation, la palette 12 s'est déplacée le long de l'évidement jusqu'à la mise en contact de la protubérance 14 de la roue 2a avec la palette 12 du micro-contact 11, et le basculement de cette palette 2 sous l'effet de la came formée par la protubérance 14. Ce basculement de la palette 12 a ensuite entraîné l'alimentation, et donc l'actionnement du moteur électrique M.
Sur la figure 17, le dispositif de commande est en cours d'armement et l'arbre de commande 2 ainsi que sa roue associée 2a se sont encore déplacé en rotation d'un angle de sensiblement 180°, par rapport à la position de la figure précédente.On the Figures 7 to 9 , the control device is being closed, the so-called first wheel 3 having moved in the direction of clockwise. During this movement, the disengaged position is maintained during the entire duration of the closure in that the annular sector 8 of the first wheel 3 cooperates with the disengaging cone 9 during this period, the length of the annular sector 8 corresponding substantially to the length of the closing stroke.
On the Figures 10 and 11 , the control device is in the closed position disarmed. To arrive at this position, the so-called first wheel 3 has moved in rotation in the direction of clockwise. The annular sector 8 has left the release cone 9 bringing the two wheels 3.6 closer together relative to each other, via a spring 13 placed between the frame and the wheel called second and suitable to recall the so-called second wheel 6 towards the so-called first wheel 3. This displacement of the so-called second wheel 6 under the effect of the spring, causes the rotation of the so-called second wheel 6 with the so-called first gear 7, thereby restoring the mechanical connection between the motorization device M and the control shaft 2, so as to allow the reset of the closing spring 1 by driving the control shaft 2 by means of the motor device M.
The figure 14 illustrates the use according to a particular embodiment of a microswitch 11 for providing power to the electric motor M of the gearbox, depending on the position of the control device.
This micro-contact 11 comprises a pallet 12 adapted to cooperate with a protuberance 14 forming a cam belonging to a wheel 2a integral with the control shaft 2.
For this purpose, the wheel 2a has on a little less than half of its circumference, a semi-circular recess, the aforementioned protuberance 14 being formed by the portion of the circumference of the wheel 2a complementary to that comprising the recess.
On the figure 15 , the control device is armed open position, or closed armed. In this position, the pallet 12 of the microswitch 11 is in the high position, because the pallet 12 is in the recess, which implies that the microswitch 11 is not actuated and therefore, that the electric motor M is not powered.
On the figure 16 , the control shaft 2 and its associated wheel 2a have rotated at an angle of about 180 ° in the counterclockwise direction, to bring the control device in the closed position disarmed.
During this rotation, the pallet 12 has moved along the recess until the protuberance 14 of the wheel 2a comes into contact with the pallet 12 of the microswitch 11, and the tilting of this pallet 2 under the effect of the cam formed by the protrusion 14. This tilting of the pallet 12 then led to the supply, and therefore the actuation of the electric motor M.
On the figure 17 , the control device is being armed and the control shaft 2 and its associated wheel 2a have further rotated by an angle of substantially 180 °, relative to the position of the previous figure.

Pendant cette course en rotation, la protubérance 14 formant came agit toujours sur la palette 12 de manière que le moteur M du réducteur soit toujours alimenté.During this rotational stroke, the cam protrusion 14 always acts on the pallet 12 so that the motor M of the gearbox is always powered.

On remarque également sur les figures 14 à 17, la présence de cliquets anti-retour coopérant avec la roue 2a.We also note on Figures 14 to 17 , the presence of non-return pawls cooperating with the wheel 2a.

Selon une autre réalisation non illustrée, un coulisseau peut être relié mécaniquement à la roue dite seconde et permettre d'actionner un micro-contact lors du coulissement de la seconde roue 6 de manière à synchroniser l'alimentation du moteur électrique M.According to another embodiment not illustrated, a slider may be mechanically connected to the so-called second wheel and allow to actuate a micro-contact during the sliding of the second wheel 6 so as to synchronize the power supply of the electric motor M.

On a donc réalisé grâce à l'invention, un dispositif de maintien du débrayage durant la fermeture de l'appareil permettant de supprimer les chocs encaissés par les pignons de débrayage durant la fermeture de l'appareil, par exemple les claquements, sollicitations par chocs des tenons, inertie, etc...comme ceci était le cas pour une motorisation avec un train d'engrenage toujours en prise avec l'arbre principal du dispositif de commande.Thus, thanks to the invention, a device for maintaining the clutch during the closing of the device has been made to eliminate the shocks collected by the clutch release gears during the closure of the device, for example slamming, shock loading. tenons, inertia, etc ... as was the case for an engine with a gear train still engaged with the main shaft of the control device.

La présente invention permet donc d'améliorer la tenue en endurance mécanique du dispositif de débrayage de la motorisation.The present invention thus makes it possible to improve the mechanical endurance of the disengagement device of the motorization.

Ce dispositif permet de débrayer la motorisation en fin d'armement de la commande pour ne pas l'endommager prématurément et également de débrayer la motorisation durant la fermeture du disjoncteur, pour ne pas entraîner le train d'engrenages de la motorisation et le détériorer et pour ne pas perturber la fermeture de la commande. Ce dispositif utilise la propriété que les engrenages à profil de dentures droites en développantes de cercles ne transmettent pas d'effort axial.
Ce dispositif n'utilise pas l'inertie et l'énergie cinétique des engrenages de la motorisation produite par la vitesse de rotation de l'arbre et le rapport de réduction. Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et illustrés qui n'ont été donnés qu'à titre d'exemple.This device makes it possible to disengage the motorization at the end of arming of the control so as not to damage it prematurely and also to disengage the motorization during the closure of the circuit breaker, so as not to drive the gear train of the engine and damage it and not to disturb the closing of the order. This device uses the property that the gears with a profile of right teeth in involute circles do not transmit axial force.
This device does not use the inertia and kinetic energy of the gears of the motorization produced by the speed of rotation of the shaft and the reduction ratio. Of course, the invention is not limited to the embodiments described and illustrated which have been given by way of example.

Au contraire, l'invention comprend tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci sont réalisées suivant son esprit.On the contrary, the invention comprises all the technical equivalents of the means described and their combinations if they are carried out according to its spirit.
