Description

La présente invention concerne d'une manière générale les interfaces d'adaptation à insérer entre un interrupteur différentiel et un ou plusieurs auxiliaires électriques normalement conçus pour être associés à des disjoncteurs.The present invention relates generally the adaptation interfaces to be inserted between a switch differential and one or more electrical auxiliaries normally designed to be combined with circuit breakers.

Par auxiliaires électriques, on entend ici, de manière usuelle, des appareils électriques destinés à assurer des fonctions annexes, telles que, par exemple, des fonctions de déclenchement, de commutation et/ou de signalisation.By electrical auxiliaries is meant here, so usual, electrical devices intended to ensure additional functions, such as, for example, triggering, switching and / or signaling.

Ils doivent être actionnés lorsque, suivant un processus de déclenchement qui lui est propre, l'interrupteur différentiel passe de son état de fermeture à son état d'ouverture, et c'est précisément l'une des fonctions de l'interface d'adaptation d'assurer, alors, de l'interrupteur différentiel aux auxiliaires électriques, le transit de l'ordre de déclenchement correspondant.They must be activated when, according to a its own triggering process, the switch differential goes from its closed state to its state opening, and this is precisely one of the functions of the adaptation interface to ensure, then, the switch differential to electrical auxiliaries, order transit corresponding trigger.

La présente invention vise plus particulièrement le cas où celui au moins des auxiliaires électriques qui est directement accolé à l'interface d'adaptation est un auxiliaire électrique émetteur, c'est-à-dire un appareil électrique qui, de manière autonome, et à la manière de l'interrupteur différentiel, est lui aussi susceptible d'être, dans des conditions données, l'objet d'un processus de déclenchement.The present invention relates more particularly to the case where that at least of the electrical auxiliaries which is directly attached to the adaptation interface is an auxiliary electrical transmitter, i.e. an electrical device which, independently, and like a switch differential, is also likely to be, in given conditions, the subject of a triggering process.

Une autre des fonctions de l'interface d'adaptation est alors de faire transiter, de cet auxiliaire électrique à l'interrupteur différentiel, l'ordre de déclenchement correspondant.Another of the functions of the adaptation interface is then to pass, from this electrical auxiliary to the differential switch, the tripping order corresponding.

La présente invention vise, enfin, plus particulièrement, le cas où, comme décrit dans la demande de brevet européen qui, déposée sous le No 94402356.3, le 20 octobre 1994, a été publiée sous le No 0 650 178, l'interface d'adaptation comporte, dans un boítier, pour assurer l'ensemble de ses fonctions, un levier d'entrée, qui, monté pivotant sur le boítier, en un premier point fixe de celui-ci, est susceptible d'être actionné par l'interrupteur différentiel, un levier d'entrée et de sortie, qui, monté pivotant sur le boítier, en un deuxième point fixe de celui-ci écarté du premier, est susceptible d'être actionné par un auxiliaire électrique ou d'actionner celui-ci, un levier intermédiaire, qui, accouplé au levier d'entrée par un montage à boutonnière, est articulé en ciseaux au levier d'entrée et de sortie de manière à entraíner celui-ci avec lui lorsqu'il est lui-même entraíné par le levier d'entrée, et un levier de sortie, qui, monté pivotant sur le boítier, en un troisième point fixe de celui-ci, est susceptible de commander en déclenchement l'interrupteur différentiel en réponse à une action de l'auxiliaire électrique sur le levier d'entrée, et qui, pour ce faire, est sous le contrôle du levier intermédiaire.The present invention aims, finally, more in particular, the case where, as described in the request for European patent which, filed under No. 94402356.3, on 20 October 1994, was published under No 0 650 178, the interface adapter includes, in a housing, to ensure the whole of its functions, an input lever, which, pivotally mounted on the housing, at a first fixed point thereof, is capable of being actuated by the differential switch, an input and output lever, which, pivotally mounted on the housing, at a second fixed point therefrom away from first, can be operated by an auxiliary electric or actuate it, an intermediate lever, which, coupled to the input lever by a buttonhole mounting, is articulated in scissors to the entry and exit lever of so as to bring him with him when he is himself driven by the input lever, and an output lever, which, pivotally mounted on the housing, at a third fixed point of this one, is likely to command in triggering the differential switch in response to an action of the electrical auxiliary on the input lever, and which, for doing this is under the control of the intermediate lever.

Dans la demande de brevet européen No 0 650 178, cette interface d'adaptation est dépourvue de toute source autonome d'énergie, l'énergie dont elle a besoin pour transmettre d'un appareil électrique à un autre un ordre de déclenchement lui étant fournie par celui de ces appareils électriques qui, faisant office d'appareil électrique émetteur, est à l'origine de cet ordre de déclenchement, tant dans le cas où cet appareil électrique émetteur est l'interrupteur différentiel que dans le cas où il s'agit de l'auxiliaire électrique associé.In European patent application No. 0 650 178, this adaptation interface is devoid of any autonomous source energy, the energy it needs to transmit from a electrical appliance to another a trip order him being supplied by that of these electrical devices which, acting as a transmitting electrical device, is at the origin of this trigger order, both in case this device electric transmitter is the differential switch that in the case where it is the associated electrical auxiliary.

Cette disposition, qui conduit avantageusement à une relative simplicité de construction, donne satisfaction, notamment lorsque l'interrupteur différentiel est un interrupteur différentiel bipolaire.This arrangement, which advantageously leads to a relative simplicity of construction, gives satisfaction, especially when the differential switch is a bipolar differential switch.

Mais elle peut s'avérer en défaut, notamment lorsque cet interrupteur différentiel est un interrupteur différentiel tétrapolaire.But it can prove to be in default, especially when this differential switch is a differential switch four-pole.

En effet, un interrupteur différentiel tétrapolaire peut, pour son déclenchement, nécessiter une énergie relativement importante, qu'un simple auxiliaire électrique ne suffit pas alors à fournir.Indeed, a four-pole differential switch may, for its triggering, require energy relatively important, that a simple electrical auxiliary does then not sufficient to provide.

La présente invention a d'une manière générale pour objet une disposition permettant de pallier cette insuffisance.The present invention generally has for subject a provision to overcome this shortcoming.

De manière plus précise, elle a pour objet une interface d'adaptation à insérer entre un interrupteur différentiel et un auxiliaire électrique, du genre comportant, dans un boítier, comme succinctement exposé ci-dessus, un levier d'entrée, qui, monté pivotant sur ce boítier en un premier point fixe de celui-ci, est susceptible d'être actionné par l'interrupteur différentiel, un levier d'entrée et de sortie, qui, monté pivotant sur le boítier en un deuxième point fixe de celui-ci écarté du premier, est susceptible d'être actionné par l'auxiliaire électrique ou d'actionner celui-ci, un levier intermédiaire, qui, accouplé au levier d'entrée par un montage à boutonnière, est articulé en ciseaux au levier d'entrée et de sortie de manière à entraíner celui-ci avec lui lorsqu'il est lui-même entraíné par le levier d'entrée, et un levier de sortie, qui, monté pivotant sur le boítier en un troisième point fixe de celui-ci, est susceptible de commander en déclenchement l'interrupteur différentiel en réponse à une action de l'auxiliaire électrique sur le levier d'entrée et de sortie, et qui, pour ce faire, est sous le contrôle du levier intermédiaire, cette interface d'adaptation étant d'une manière générale caractérisée en ce que, à son levier de sortie, sont associés, d'une part, des moyens élastiques, qui sollicitent en permanence le levier de sortie dans le sens pour lequel il est apte à commander en déclenchement l'interrupteur différentiel, et, d'autre part, un levier de retenue, avec lequel il est susceptible d'être en prise par des moyens d'accrochage, et par l'intermédiaire duquel il est sous le contrôle du levier intermédiaire.More specifically, it relates to a adaptation interface to be inserted between a switch differential and an electrical auxiliary, of the type comprising, in a case, as succinctly explained above, a input lever, which, pivotally mounted on this housing in one first fixed point of it, is likely to be actuated by the differential switch, an input lever and outlet, which, pivotally mounted on the housing at a second point fixed from it removed from the first, is likely to be actuated by the electrical auxiliary or actuating it, an intermediate lever, which, coupled to the input lever by buttonhole mounting, scissor-hinged entry and exit so as to bring it with him when it is itself driven by the input lever, and a output lever, which, pivotally mounted on the housing in one third fixed point of it, is likely to command in tripping the differential switch in response to a action of the electrical auxiliary on the input lever and exit, and which, to do this, is under the control of the lever intermediate, this adaptation interface being in a way general characterized in that, at its output lever, are associated, on the one hand, elastic means, which stress permanently the output lever in the direction for which it is able to command the switch on tripping differential, and, on the other hand, a retaining lever, with which he is likely to be engaged by means hooking, and through which it is under the control of the intermediate lever.

Ainsi, si, comme précédemment, lors d'un déclenchement de l'auxiliaire électrique par l'interrupteur différentiel, l'énergie nécessaire à ce déclenchement est exclusivement fournie par l'interrupteur différentiel, il n'en est pas de même lors d'un déclenchement de l'interrupteur différentiel par l'auxiliaire électrique.So if, as before, when triggered of the electrical auxiliary by the differential switch, the energy required for this trigger is exclusively provided by the differential switch, there is none even when the differential switch trips the electrical auxiliary.

Dans ce cas, en effet, les moyens élastiques associés au levier de sortie, préalablement mis sous contrainte à cet effet, restituent, avantageusement, à la rupture des moyens d'accrochage correspondants, l'énergie qui s'y trouve accumulée, en fournissant, ainsi, à l'interrupteur différentiel, le complément d'énergie éventuellement nécessaire à son déclenchement. In this case, in fact, the associated elastic means to the exit lever, previously put under constraint to this effect, advantageously restore when resources break corresponding hooking, the energy therein accumulated, thereby providing the switch differential, the additional energy that may be required when triggered.

Ce déclenchement se produit donc en toute sûreté.This trigger therefore occurs safely.

En pratique, la mise sous contrainte préalable des moyens élastiques ainsi prévus suivant l'invention se fait lors même de l'enclenchement de l'interrupteur différentiel, et l'énergie correspondante est donc tout naturellement fournie par l'opérateur qui agit en conséquence sur la manette de cet interrupteur différentiel.In practice, prior stressing of elastic means thus provided according to the invention is done during even when the differential switch is engaged, and the corresponding energy is therefore quite naturally supplied by the operator who acts accordingly on the joystick of this Differential Switch.

Ainsi donc, de ce point de vue, l'interface d'adaptation suivant l'invention ne nécessite avantageusement pas par elle-même une quelconque manette, même si, pour d'autres raisons, qui seront explicitées ultérieurement, elle est en pratique équipée d'une telle manette.So therefore, from this point of view, the interface adaptation according to the invention advantageously does not require not by itself any controller, even if, for other reasons, which will be explained later, it is in practice equipped with such a joystick.

Son mécanisme s'en trouve avantageusement simplifié.Its mechanism is advantageously simplified.

En outre, les moyens élastiques fournissant suivant l'invention l'énergie complémentaire éventuellement nécessaire au déclenchement de l'interrupteur différentiel interviennent avantageusement, sans un quelconque intermédiaire, sur le levier de sortie même de cette interface d'adaptation, au plus près, ainsi, de leur utilisation, et au bénéfice, donc, de leur rendement, et, partant, de leur efficacité.In addition, the elastic means providing following the invention the additional energy possibly necessary when the differential switch trips advantageously, without any intermediary, on the even output lever of this adaptation interface, at most close, thus, to their use, and to the benefit, therefore, of their performance, and therefore their effectiveness.

  • Tel qu'illustré sur la figure 1, l'interface d'adaptation 10 suivant l'invention est destiné à être inséré entre, d'une part, un interrupteur différentiel 11, et, d'autre part, un ou plusieurs auxiliaires électriques 12.As illustrated in Figure 1, the interface adapter 10 according to the invention is intended to be inserted between, on the one hand, a differential switch 11, and, on the other share, one or more electrical auxiliaries 12.

    Tous ces appareils électriques constituent en pratique des appareils électriques modulaires, leurs boítiers respectifs se présentant tous sous la forme de plaquettes de même contour, seule variant, éventuellement, de l'un à l'autre, la largeur ou épaisseur.All these electrical devices constitute in practice modular electrical devices, their respective housings all in the form of plates with the same outline, only varying, possibly, from one to another, the width or thickness.

    Tous ces appareils électriques sont en outre destinés à être disposés en ligne sur un même support, en pratique un rail normalisé, en étant successivement accolés les uns aux autres par les faces principales de leurs boítiers.All these electrical devices are also intended to be arranged online on the same support, in practice a standard rail, being successively joined to each other others by the main faces of their cases.

    L'interrupteur différentiel 11 ne relevant pas, par lui-même, de la présente invention, il ne sera pas décrit ici. The differential switch 11 does not fall, for itself, of the present invention, it will not be described here.

    Il suffira d'indiquer qu'il comporte un support de contacts monté mobile, et, plus précisément, rotatif, dans son boítier, que, suivant un processus de déclenchement qui lui est propre, il est susceptible de passer d'un état de fermeture, pour lequel des contacts mobiles portés par ce support de contacts sont appliqués à des contacts fixes, à un état d'ouverture, pour lequel, au contraire, ces contacts mobiles sont écartés de ces contacts fixes, et que, pour son enclenchement, ou réarmement, c'est-à-dire pour son retour à son état de fermeture, il comporte, en façade, à la disposition de l'usager, une manette 13.It will suffice to indicate that it includes a support for contacts mounted mobile, and, more precisely, rotary, in its housing, that, following a triggering process which is its clean, it is likely to go from a closed state, for which mobile contacts carried by this support contacts are applied to fixed contacts, to a state opening, for which, on the contrary, these movable contacts are moved away from these fixed contacts, and that for its activation, or rearming, i.e. for its return to its closed state, it has, on the front, available of the user, a joystick 13.

    Les auxiliaires électriques 12, qui sont au nombre de deux dans la forme de mise en oeuvre représentée, ne relèvent pas non plus par eux-mêmes de la présente invention, et ils ne seront donc pas non plus décrits ici.The electrical auxiliaries 12, which are two in the embodiment shown, do not fall under also by themselves of the present invention, and they do not will therefore not be described here either.

    Il suffira d'indiquer qu'il s'agit en pratique d'auxiliaires électriques 12 émetteurs, c'est-à-dire d'appareils électriques qui, outre d'autres éventuelles fonctions, sont eux aussi susceptibles d'être, de manière autonome, l'objet d'un processus de déclenchement, et que, pour leur enclenchement, ou réarmement, ils comportent, en façade, à la disposition de l'usager, une manette 14.It will suffice to indicate that it is in practice electrical auxiliaries 12 transmitters, i.e. electrical appliances which, in addition to other possible functions, are also likely to be, so autonomous, the subject of a triggering process, and that, for their engagement, or rearming, they include, on the front, available to the user, a joystick 14.

    Entre l'interface d'adaptation 10 et l'interrupteur différentiel 11 interviennent, à travers leurs boítiers respectifs, et tel que schématisé en traits interrompus sur la figure 1, deux liaisons mécaniques L1, L2.Between the adaptation interface 10 and the switch differential 11 intervene, through their cases respective, and as shown in broken lines on the Figure 1, two mechanical connections L1, L2.

    L'une et l'autre sont des liaisons mécaniques unidirectionnelles.Both are mechanical connections unidirectional.

    La liaison mécanique L1 constitue pour l'interface d'adaptation 10 une liaison mécanique d'entrée par laquelle elle est susceptible d'être actionnée par un organe du mécanisme de l'interrupteur différentiel 11, constitué, en pratique, par l'arbre du support de contacts que comporte celui-ci.The mechanical connection L1 constitutes for the interface adapter 10 a mechanical input connection through which it can be activated by an organ of the mechanism of the differential switch 11, consisting of practical, using the contact support shaft this one.

    Corollairement, la liaison mécanique L2 constitue pour l'interface d'adaptation 10 une liaison mécanique de sortie par laquelle un organe de son propre mécanisme est susceptible d'actionner l'interrupteur différentiel 11.As a corollary, the mechanical link L2 constitutes for the adaptation interface 10 a mechanical output connection by which an organ of its own mechanism is susceptible actuate the differential switch 11.

    De même, il est prévu, entre l'interface d'adaptation 10 et l'auxiliaire électrique 12 qui lui est immédiatement adjacent, et, ainsi de suite, d'un auxiliaire électrique 12 à un autre, une liaison mécanique L3.Similarly, provision is made between the adaptation interface 10 and the electrical auxiliary 12 immediately thereto adjacent, and, so on, an electrical auxiliary 12 to another, an L3 mechanical link.

    Mais, à la différence des précédentes, cette liaison mécanique L3 est une liaison mécanique bidirectionnelle par laquelle, d'une part, l'interface d'adaptation 10 est apte à actionner l'auxiliaire électrique 12 immédiatement adjacent en réponse à un déclenchement de l'interrupteur différentiel 11, et, de proche en proche, les autres auxiliaires électriques 12, et par laquelle, d'autre part, elle est également apte à être actionnée par cet auxiliaire électrique 12 immédiatement adjacent, en réponse, éventuellement, au déclenchement d'un auxiliaire électrique 12 plus éloigné, pour le déclenchement de l'interrupteur différentiel 11.But, unlike the previous ones, this connection mechanical L3 is a bidirectional mechanical connection by which, on the one hand, the adaptation interface 10 is suitable for activate the electrical auxiliary 12 immediately adjacent by response to tripping of the differential switch 11, and, step by step, the other electrical auxiliaries 12, and by which, on the other hand, it is also able to be actuated by this electrical auxiliary 12 immediately adjacent, possibly in response to the triggering of a electrical auxiliary 12 further away, for triggering of the differential switch 11.

    Pour faciliter le réarmement de l'ensemble à la suite d'un tel déclenchement, c'est-à-dire pour le retour de cet ensemble à un état d'enclenchement, il est prévu, dans la forme de mise en oeuvre représentée, et tel que schématisé en traits interrompus sur la figure 1, une liaison mécanique L4 qui relie successivement la manette 13 de l'interrupteur différentiel 11 aux manettes 14 des auxiliaires électriques 12.To facilitate the rearming of the whole following of such a trigger, i.e. for the return of this together in an engaged state there is provision, in the form of implementation shown, and as shown schematically in lines interrupted in Figure 1, a mechanical link L4 which connects successively the lever 13 of the differential switch 11 to the levers 14 of the electrical auxiliaries 12.

    Il suffit, ainsi, de réarmer l'interrupteur différentiel 11 pour que, conjointement, les auxiliaires électriques 12 soient eux aussi systématiquement réarmés. Par mesure de commodité, l'interface d'adaptation 10 suivant l'invention comporte, elle-même, en façade, dans la forme de réalisation représentée, une manette 15, qui, en pratique, n'est là que pour assurer, à la manière d'une entretoise, la continuité de la liaison mécanique L4, sans avoir par ailleurs, ainsi qu'il apparaítra ci-après, une quelconque incidence sur le fonctionnement de cette interface d'adaptation 10.All you have to do is reset the switch differential 11 so that, jointly, the auxiliaries 12 are also systematically rearmed. For convenience, the adaptation interface 10 according to the invention comprises, itself, on the front, in the illustrated embodiment, a lever 15, which, in practical, is only there to ensure, like a spacer, the continuity of the mechanical link L4, without also have, as will appear below, a any impact on the functioning of this interface adaptation 10.

    Les dispositions qui précèdent sont bien connues par elles-mêmes, et elles ne seront donc pas décrites plus en détail ici. The foregoing provisions are well known by themselves, and therefore will not be described further in detail here.

    De manière également connue en soi par la demande de brevet européen No 0 650 178, l'interface d'adaptation 10 comporte, globalement, dans un boítier 16 dont seul le socle 18 est représenté sur les figures 2 à 9, un levier d'entrée 20, qui, monté pivotant sur le boítier 16 en un premier point fixe A1 de celui-ci, est susceptible d'être actionné par l'interrupteur différentiel 11, un levier d'entrée et de sortie 21, qui, monté pivotant sur le boítier 16 en un deuxième point fixe A2 de celui-ci écarté du premier, est susceptible d'être actionné par l'auxiliaire électrique 12 immédiatement adjacent ou d'actionner celui-ci, un levier intermédiaire 22, qui, accouplé au levier d'entrée 20 par un montage à boutonnière détaillé ultérieurement, est articulé en ciseaux au levier d'entrée et de sortie 21 de manière à entraíner celui-ci avec lui lorsqu'il est lui-même entraíné par le levier d'entrée 20, et un levier de sortie 24, qui, monté pivotant sur le boítier 16 en un troisième point fixe A3 de celui-ci, est susceptible de commander en déclenchement l'interrupteur différentiel 11 en réponse à une action de l'auxiliaire électrique 12 en question sur le levier d'entrée et de sortie 21, et qui, pour ce faire, est sous le contrôle du levier intermédiaire 22.In a manner also known per se by the request for European patent No 0 650 178, the adaptation interface 10 comprises, overall, in a housing 16 of which only the base 18 is shown in FIGS. 2 to 9, an input lever 20, which, pivotally mounted on the housing 16 at a first fixed point A1 of it, is likely to be actuated by the differential switch 11, an input and output lever 21, which, pivotally mounted on the housing 16 at a second point fixed A2 of it removed from the first, is likely to be actuated by the electrical auxiliary 12 immediately adjacent or actuate it, an intermediate lever 22, which, coupled to the input lever 20 by a buttonhole mounting detailed later, is articulated in scissors with the lever input and output 21 so as to train it with him when he is himself driven by the input lever 20, and an output lever 24, which, pivotally mounted on the housing 16 at a third fixed point A3 thereof, is susceptible to command the differential switch 11 to trip in response to an action of the electrical auxiliary 12 in question about the input and output lever 21, and which, for this is done under the control of the intermediate lever 22.

    Par "point fixe" du boítier 16, on entend, ici, par simple commodité, une zone de ce boítier 16 par laquelle se fait une rotation autour d'un axe dont la trace sur le fond 25 du socle 18 de ce boítier 16 est un simple point, tel que schématisé sur la figure 5.By "fixed point" of the housing 16 is meant here by simple convenience, an area of this housing 16 through which rotates around an axis, the trace of which on the bottom 25 of the base 18 of this housing 16 is a single point, such as shown schematically in Figure 5.

    Dans la forme de réalisation représentée, le levier d'entrée 20 se présente sous la forme générale d'un flasque.In the embodiment shown, the lever inlet 20 is in the general form of a flange.

    Dans sa zone médiane, il présente, en saillie sur celle de ses faces qui est tournée vers le fond 25 du socle 18 du boítier 16, un moyeu 26 par lequel il est en prise à rotation avec une ouverture 27 de ce fond 25, suivant le point fixe A1 du boítier 16.In its middle zone, it presents, projecting from that of its faces which faces towards the bottom 25 of the base 18 of the housing 16, a hub 26 by which it is engaged rotation with an opening 27 of this bottom 25, along the point fixed A1 of the housing 16.

    Sur ce moyeu 26, fait saillie, axialement, un doigt 28 appartenant à la liaison mécanique L1.On this hub 26, protrudes, axially, a finger 28 belonging to the mechanical link L1.

    Autrement dit, ce doigt 28, qui présente des méplats, est destiné à venir en prise à rotation avec l'arbre du support de contacts que comporte l'interrupteur différentiel 11.In other words, this finger 28, which has flats, is intended to come into rotation with the support shaft of contacts included in the differential switch 11.

    De part et d'autre du moyeu 26, le levier d'entrée 20 forme globalement deux bras 30, 31.On either side of the hub 26, the input lever 20 generally forms two arms 30, 31.

    Le bras 30 présente une encoche 32, qui est allongée suivant sa longueur, à la manière d'une fente, et avec laquelle est en prise un ergot 34 prévu à cet effet sur le levier intermédiaire 22, l'ensemble constituant le montage à boutonnière intervenant entre le levier d'entrée 20 et ce levier intermédiaire 22.The arm 30 has a notch 32, which is elongated along its length, like a slit, and with which is engaged a lug 34 provided for this purpose on the lever intermediate 22, the assembly constituting the mounting buttonhole intervening between the input lever 20 and this intermediate lever 22.

    L'autre bras 31 du levier d'entrée 20 a un plan général qui est légèrement décalé par rapport à celui du bras 30, et il présente, lui, en saillie, pour des raisons qui apparaítront ci-après, du côté opposé au moyeu 26, un pivot 35, qui, en pratique, se trouve dans l'alignement de l'encoche 32.The other arm 31 of the input lever 20 has a plane general which is slightly offset from that of the arm 30, and he presents, for its part, for reasons which will appear below, on the side opposite to the hub 26, a pivot 35, which, in practice, is in alignment with the notch 32.

    Dans la forme de réalisation représentée, le levier d'entrée et de sortie 21 comporte, lui aussi, de part et d'autre d'une zone médiane sur laquelle fait saillie, sur la face tournée vers le fond 25 du socle 18 du boítier 16, un pivot 36, deux bras 38, 39.In the embodiment shown, the lever input and output 21 also includes both on the other side of a median zone on which protrudes, on the face turned towards the bottom 25 of the base 18 of the housing 16, a pivot 36, two arms 38, 39.

    Le bras 38 comporte une lumière 40, qui se prolonge à la faveur d'un manchon 41 présent en saillie sur la même face que le pivot 36, et à la faveur de laquelle peut intervenir, en pratique avec jeu, un doigt, non représenté, appartenant au mécanisme de l'auxiliaire électrique 12 immédiatement adjacent, l'ensemble constituant la liaison mécanique L3 correspondante.The arm 38 has a lumen 40, which extends to favored by a sleeve 41 projecting from the same face that pivot 36, and thanks to which can intervene, in practice with play, a finger, not shown, belonging to the electric auxiliary mechanism 12 immediately adjacent, the assembly constituting the corresponding mechanical connection L3.

    En pratique, dans la forme de réalisation représentée, la lumière 40 a un contour rectangulaire.In practice, in the embodiment shown, the light 40 has a rectangular outline.

    Comme précédemment, le plan général du bras 39 est décalé par rapport à celui du bras 38.As before, the general plan of arm 39 is offset from that of arm 38.

    Il est ainsi formé, longitudinalement, sur ce levier d'entrée et de sortie 21, un épaulement 42, pour l'appui du levier intermédiaire 22.It is thus formed, longitudinally, on this lever inlet and outlet 21, a shoulder 42, for supporting the intermediate lever 22.

    Le bras 39 du levier d'entrée et de sortie 21 présente en outre une oreille 43, qui se prolonge à la faveur d'une douille 44, et par laquelle il est engagé à rotation sur un axe 45 présent à cet effet en saillie sur le fond 25 du socle 18 du boítier 16, suivant le point fixe A2 de celui-ci. The arm 39 of the input and output lever 21 has additionally an ear 43, which is extended by means of a socket 44, and by which it is rotatably engaged on an axis 45 for this purpose projecting from the bottom 25 of the base 18 of the housing 16, according to the fixed point A2 thereof.

    Par une oreille 46 appartenant à sa zone médiane, le levier intermédiaire 22 est engagé à rotation sur le pivot 36 du levier d'entrée et de sortie 21, et, de part et d'autre de cette oreille 46, il présente, lui aussi, deux bras 47, 48.By an ear 46 belonging to its median zone, the intermediate lever 22 is rotatably engaged on pivot 36 of the input and output lever 21, and, on either side of this ear 46, it also has two arms 47, 48.

    Le bras 47 est globalement cintré, pour contourner le manchon 41 du levier d'entrée et de sortie 21.The arm 47 is generally curved, to bypass the sleeve 41 of the input and output lever 21.

    Il porte, à son extrémité, l'ergot 34 par lequel le levier intermédiaire 22 est en prise avec l'encoche 32 du levier d'entrée 20.It carries, at its end, the lug 34 by which the intermediate lever 22 is engaged with the notch 32 of the input lever 20.

    Le plan général du bras 48 du levier intermédiaire 22 est décalé par rapport à celui du bras 47, mais dans le sens inverse du décalage existant corollairement entre les deux bras 38, 39 du levier d'entrée et de sortie 21.The general plan of the arm 48 of the intermediate lever 22 is offset from that of arm 47, but in the direction inverse of the corollary existing offset between the two arms 38, 39 of the input and output lever 21.

    Le levier intermédiaire 22 et le levier d'entrée et de sortie 21 s'entrecroisent ainsi l'un l'autre de part et d'autre de leur zone médiane d'articulation, à la manière des deux lames d'une paire de ciseaux.The intermediate lever 22 and the input and exit 21 thus intersect each other on both sides of their median articulation zone, like the two blades of a pair of scissors.

    Le bras 48 du levier intermédiaire 22 s'étend de ce fait au-delà du bras 39 du levier d'entrée et de sortie 21 par rapport au levier d'entrée 20, et donc, par rapport au fond 25 du socle 18 du boítier 16.The arm 48 of the intermediate lever 22 extends from this done beyond the arm 39 of the input and output lever 21 by relative to the input lever 20, and therefore, relative to the bottom 25 of the base 18 of the housing 16.

    Pour des raisons qui apparaítront ci-après, ce bras 48 porte, en saillie, à son extrémité, sur sa face opposée, un pivot 50.For reasons which will appear below, this arm 48 carries, projecting, at its end, on its opposite face, a pivot 50.

    Le levier de sortie 24 présente, lui aussi, dans sa zone médiane, une oreille 52, par laquelle il est engagé à rotation sur un axe 53 prévu à cet effet en saillie sur le fond 25 du socle 18 du boítier 16, suivant le troisième point fixe A3 de celui-ci.The output lever 24 also has, in its middle area, one ear 52, through which it is engaged to rotation on an axis 53 provided for this purpose projecting on the bottom 25 of the base 18 of the housing 16, according to the third fixed point A3 of it.

    De part et d'autre de cette oreille 52, il comporte, globalement, deux bras 54, 55.On either side of this ear 52, it comprises, overall, two arms 54, 55.

    Le bras 54 porte en saillie, en direction du fond 25 du socle 18 du boítier 16, un doigt 56 qui, à la faveur d'une lumière 57 de ce fond 25, fait saillie hors de ce socle 18, pour participer à la constitution de la liaison mécanique L2.The arm 54 carries projecting, towards the bottom 25 of the base 18 of the housing 16, a finger 56 which, thanks to a light 57 of this bottom 25, protrudes out of this base 18, to participate in the constitution of the mechanical link L2.

    Pour des raisons qui apparaítront ci-après, le bras 55 présente, lui-même, en saillie, sur la même face que celle sur laquelle fait saillie ce doigt 56, un doigt 58.For reasons which will appear below, the arm 55 presents, itself, projecting, on the same face as that on which protrudes this finger 56, a finger 58.

    Suivant l'invention, au levier de sortie 24 sont associés, d'une part, des moyens élastiques 59, qui sollicitent en permanence ce levier de sortie 24 dans le sens pour lequel il est apte à commander en déclenchement l'interrupteur différentiel 11, et, d'autre part, un levier de retenue 60, avec lequel il est susceptible d'être en prise par des moyens d'accrochage 61, et par l'intermédiaire duquel il est sous le contrôle du levier intermédiaire 22.According to the invention, the output lever 24 are associated, on the one hand, elastic means 59, which stress permanently this output lever 24 in the direction for which it is able to trigger the switch differential 11, and, on the other hand, a retaining lever 60, with whom he is likely to be engaged by means hook 61, and through which it is under the control of the intermediate lever 22.

    Dans la forme de réalisation représentée, le levier de retenue 60 est monté pivotant sur le boítier 16 en un quatrième point fixe A4 de celui-ci.In the embodiment shown, the lever retainer 60 is pivotally mounted on the housing 16 in a fourth fixed point A4 of it.

    En pratique, il comporte, dans sa zone médiane, une oreille 62, par laquelle il est engagé à rotation sur un axe 64 prévu à cet effet en saillie sur le fond 25 du socle 18 du boítier 16, suivant ce quatrième point fixe A4.In practice, it includes, in its middle zone, a ear 62, by which it is rotatably engaged on an axis 64 provided for this purpose projecting from the bottom 25 of the base 18 of the box 16, along this fourth fixed point A4.

    De part et d'autre de cette oreille 62, qui se prolonge à la faveur d'une douille 65, le levier de retenue 60 présente deux bras 66, 67.On either side of this ear 62, which is extends by means of a socket 65, the retaining lever 60 has two arms 66, 67.

    Les moyens d'accrochage 61 interviennent entre le bras 66 et un bec 69 que comporte latéralement en saillie à cet effet le bras 54 correspondant du levier de sortie 24.The hooking means 61 intervene between the arm 66 and a spout 69 which has laterally projecting therefrom effect the corresponding arm 54 of the output lever 24.

    En pratique, ces moyens d'accrochage 61 comportent, sur le bras 66 du levier de retenue 60, un crochet 70, et, sur le bec 69 du levier de sortie 24, un crochet 71.In practice, these attachment means 61 comprise, on the arm 66 of the retaining lever 60, a hook 70, and, on the spout 69 of the outlet lever 24, a hook 71.

    Par des moyens élastiques 72, le levier de retenue 60 est en permanence sollicité en appui, par son bras 67, contre une butée 73 prévue pour lui sur une tirette de déclenchement 75 qui, par une oreille 76 prévue à cet effet à son extrémité opposée, est articulée au levier intermédiaire 22 à la faveur du pivot 50 que comporte en saillie le bras 48 de celui-ci.By elastic means 72, the retaining lever 60 is permanently requested to bear, by its arm 67, against a stop 73 provided for him on a trigger pull 75 which, by an ear 76 provided for this purpose at its end opposite, is articulated to the intermediate lever 22 in favor pivot 50 that projecting from arm 48 thereof.

    C'est donc par l'intermédiaire de ce levier intermédiaire 22, de la tirette de déclenchement 75, et du levier de retenue 60, que le levier de sortie 24 est sensible à une action de l'auxiliaire électrique 12 immédiatement adjacent sur le levier d'entrée et de sortie 21. It is therefore through this lever intermediate 22, trigger zipper 75, and retaining lever 60, that the output lever 24 is sensitive to an action of the electrical auxiliary 12 immediately adjacent to the entry and exit lever 21.

    Dans la forme de réalisation représentée, les moyens élastiques 72 associés au levier de retenue 60 sont constitués par un ressort de torsion, qui, par sa partie médiane de torsion 78, est engagé sur un pion 79 prévu à cet effet en saillie sur la tirette de déclenchement 75, et dont une branche 80 porte sur le bras 66 du levier de retenue 60 tandis que l'autre branche 81 prend appui sur un doigt 82 prévu à cet effet en saillie sur la tirette de déclenchement 75 parallèlement au pion 79.In the embodiment shown, the means elastic 72 associated with the retaining lever 60 are constituted by a torsion spring, which by its middle part of torsion 78, is engaged on a pin 79 provided for this purpose in projection on the trigger zipper 75, and one branch of which 80 bears on the arm 66 of the retaining lever 60 while the other branch 81 rests on a finger 82 provided for this protruding effect on trigger pull 75 parallel to pawn 79.

    Pour son guidage, la tirette de déclenchement 75 porte, latéralement, en saillie, dos à dos avec le pion 79, un ergot 83 par lequel elle est en prise avec une cuvette 84 qui, allongée en boutonnière, fait elle-même saillie sur le fond 25 du socle 18 du boítier 16.For its guidance, the trigger zipper 75 door, laterally, projecting, back to back with pin 79, a lug 83 by which it engages with a bowl 84 which, elongated in a buttonhole, protrudes itself from the bottom 25 of the base 18 of the housing 16.

    Dans la forme de réalisation représentée, au levier d'entrée 20, est articulé, à la faveur du pivot 35 que porte le bras 31 de celui-ci, un poussoir de réarmement 85, avec lequel le levier de sortie 24 est en prise par un montage à jeu.In the embodiment shown, using the lever input 20, is articulated, thanks to the pivot 35 that door the arm 31 thereof, a reset button 85, with which the output lever 24 is engaged by a mounting to Game.

    En pratique, ce poussoir de réarmement 85 s'étend sensiblement parallèlement à la tirette de déclenchement 75.In practice, this reset button 85 extends substantially parallel to the trigger zipper 75.

    A l'une de ses extrémités, qui est décalée par rapport à son plan général à la manière du bras 31 du levier d'entrée 20 mais en sens inverse par rapport à celui-ci, le poussoir de réarmement 85 comporte une oreille 86, par laquelle il est engagé à rotation sur le pivot 35 de ce bras 31.At one of its ends, which is offset from to its general plan in the manner of the arm 31 of the input lever 20 but in reverse in relation to it, the pusher reset 85 has an ear 86, through which it is engaged in rotation on the pivot 35 of this arm 31.

    Dans sa zone médiane, il comporte un large évidement 87, par lequel il contourne l'axe 64 matérialisant le quatrième point A4 du boítier 16, et, avec lui, la douille 65 du levier de retenue 60.In its middle zone, it has a large recess 87, by which it bypasses the axis 64 materializing the fourth point A4 of the housing 16, and, with it, the socket 65 of the lever restraint 60.

    Enfin, à son extrémité opposée à son oreille 86, ce poussoir de réarmement 85 comporte une lumière 88, qui est allongée, à la manière d'une boutonnière, suivant sa propre direction d'allongement, et par laquelle il est en prise avec le doigt 58 du levier de sortie 24, l'ensemble constituant le montage à jeu correspondant. Finally, at its end opposite to its ear 86, this reset button 85 has a light 88, which is elongated, like a buttonhole, following its own direction of elongation, and by which it is engaged with the finger 58 of the output lever 24, the assembly constituting the mounting with corresponding clearance.

    Dans la forme de réalisation représentée, enfin, il est prévu, globalement parallèlement à la tirette de déclenchement 75 et au poussoir de réarmement 85, un moyen de commutation 89, qui, en pratique, et comme décrit dans la demande de brevet européen No 0 650 178, est formé d'une lame 90 montée basculante entre deux contacts fixes 91.In the embodiment shown, finally, it is planned, generally parallel to the pull tab trigger 75 and the reset button 85, a means of switching 89, which in practice and as described in the European patent application No 0 650 178, is formed by a blade 90 swivel mounted between two fixed contacts 91.

    Ce moyen de commutation 89 est sous le contrôle d'un levier de basculement 92 qui, monté pivotant sur le boítier 16 autour du deuxième point fixe A2 de celui-ci, est en prise, par une fourchette 93, avec la lame 90, et qui est soumis à des moyens élastiques, explicités ci-après, qui le sollicitent en permanence en appui contre le levier d'entrée 20.This switching means 89 is under the control of a tilt lever 92 which, pivotally mounted on the housing 16 around the second fixed point A2 thereof, is engaged, by a fork 93, with the blade 90, and which is subjected to elastic means, explained below, which urge it in permanently pressing against the input lever 20.

    En pratique, ce levier de basculement 92 présente, globalement en équerre l'un par rapport à l'autre, deux bras 94, 95.In practice, this tilting lever 92 has, generally at right angles to each other, two arms 94, 95.

    A l'une de ses extrémités, le bras 94 porte la fourchette 93, et, à l'autre de ses extrémités, il comporte une oreille 96 par laquelle il est engagé à rotation sur un moyeu 97 prévu à cet effet en saillie sur le fond 25 du socle 18 du boítier 16, coaxialement autour de l'axe 45, ce moyeu 97 relevant, comme cet axe 45, du deuxième point fixe A2 de ce boítier 16.At one of its ends, the arm 94 carries the fork 93, and, at the other end, ear 96 by which it is rotatably engaged on a hub 97 provided for this purpose projecting from the bottom 25 of the base 18 of the housing 16, coaxially around the axis 45, this hub 97 falling, like this axis 45, from the second fixed point A2 of this housing 16.

    A son extrémité opposée au bras 94, le bras 95 présente un bossage 98, par lequel il est adapté à porter sur le levier d'entrée 20, et, plus précisément, sur la tranche du bras 30 de celui-ci présentant l'encoche 32.At its end opposite the arm 94, the arm 95 has a boss 98, by which it is adapted to bear on the input lever 20, and, more precisely, on the edge of the arm 30 of the latter having the notch 32.

    Suivant l'invention, les moyens élastiques 59 associés au levier de sortie 24 prennent appui sur le levier de basculement 92.According to the invention, the elastic means 59 associated at the output lever 24 press on the tilting 92.

    Ainsi, ils constituent, conjointement, par eux-mêmes, les moyens élastiques qui, associés à ce levier de basculement 92, sollicitent en permanence celui-ci en appui contre le levier d'entrée 20.Thus, they constitute, jointly, by themselves, the elastic means which, associated with this tilting lever 92, permanently request the latter to bear against the input lever 20.

    Dans la forme de réalisation représentée, ces moyens élastiques 59 sont constitués par un ressort de torsion qui, par sa partie médiane de torsion 99, est engagé sur un pion 100 prévu à cet effet en saillie sur le fond 25 du socle 18 du boítier 16, et qui, par une branche 101, porte sur le bras 54 du levier de sortie 24, à la faveur d'un doigt 102 prévu à cet effet latéralement en saillie sur celui-ci parallèlement au doigt 56, cependant que, par son autre branche 104, il porte sur le bras 95 du levier de déclenchement 92, à la faveur d'un bossage 105 également prévu latéralement en saillie sur celui-ci.In the embodiment shown, these means elastic 59 consist of a torsion spring which, by its middle part of torsion 99, is engaged on a pin 100 provided for this purpose projecting from the bottom 25 of the base 18 of the case 16, and which, by a branch 101, carries on the arm 54 of the output lever 24, by means of a finger 102 provided for this laterally protruding effect thereon parallel to the finger 56, however, by its other branch 104, it carries on the arm 95 of the trigger lever 92, thanks to a boss 105 also provided laterally projecting from this one.

    Suivant l'invention, également, le levier d'entrée 20 comporte, pour l'appui du levier de basculement 92, une surface de came 106, qui appartient à son bras 30, en étant formée par la tranche de celui-ci, et dont une portion 107, au moins, s'étend circulairement, en étant centrée sur le moyeu 26, et, donc, sur le premier point fixe A1 du boítier 16.According to the invention, also, the input lever 20 comprises, for the support of the tilting lever 92, a surface cam 106, which belongs to its arm 30, being formed by the slice of it, and of which at least a portion 107, extends circularly, being centered on the hub 26, and, therefore, on the first fixed point A1 of the housing 16.

    En pratique, la surface de came 106 comporte deux portions, à savoir, outre la portion circulaire 107, une portion rectiligne 108, qui s'étend sensiblement radialement par rapport à la portion circulaire 107.In practice, the cam surface 106 has two portions, namely, in addition to the circular portion 107, a rectilinear portion 108, which extends substantially radially relative to the circular portion 107.

    Corollairement, pour coopération avec cette surface de came 106, le bossage 98 du levier de basculement 92 comporte, en dièdre, deux pans 109, 110.As a corollary, for cooperation with this surface of cam 106, the boss 98 of the tilting lever 92 comprises, dihedral, two sides 109, 110.

    Le pan 109 s'étend en oblique par rapport à la direction d'allongement du bras 95 de ce levier de basculement 92, tandis que le pan 110 est droit, dans la mesure où, lui, il s'étend sensiblement parallèlement à cette direction d'allongement.Pan 109 extends obliquely to the direction of elongation of the arm 95 of this tilting lever 92, while the pan 110 is straight, insofar as he, it extends substantially parallel to this direction elongation.

    On supposera, tout d'abord, en référence à la figure 5, que l'interface d'adaptation 10 suivant l'invention est en configuration de repos, et que, conjointement, l'interrupteur différentiel 11 est en état d'ouverture.We will assume, first of all, with reference to the figure 5, that the adaptation interface 10 according to the invention is in rest configuration, and that together the switch differential 11 is in the open state.

    Pour cette configuration de repos, le levier d'entrée 20 est en appui contre une butée 113 prévue à cet effet sur le boítier 16, le levier de basculement 92 porte par le pan 109 oblique de son bossage 98 contre la portion rectiligne 108 de la surface de came 106 de ce levier d'entrée 20, le moyen de commutation 89 est dans un premier état, pour lequel sa lame 90 porte par exemple sur le contact fixe 91 le plus proche de la manette 15, comme représenté, le pivot 36 du levier d'entrée et de sortie 21 est sensiblement aligné avec les premier et deuxième points fixes A1, A2 du boítier 16, entre ceux-ci, la paire de ciseaux formée par ce levier d'entrée et de sortie 21 et le levier intermédiaire 22 est fermée, le levier de sortie 24 est en prise avec le levier de retenue 60, avec, cependant, un léger jeu entre son crochet 71 et le crochet 70 de celui-ci, et, sous la sollicitation des moyens élastiques 59, le doigt 58 de ce levier de sortie 24 est en butée contre celle des extrémités de la lumière 88 du poussoir de réarmement 85 qui est la plus proche du levier d'entrée 20 auquel est attelé celui-ci.For this rest configuration, the input lever 20 is in abutment against a stop 113 provided for this purpose on the housing 16, the tilting lever 92 carried by the panel 109 oblique of its boss 98 against the straight portion 108 of the cam surface 106 of this input lever 20, the means of switching 89 is in a first state, for which its blade 90 relates for example to the fixed contact 91 closest to the lever 15, as shown, the pivot 36 of the input lever and outlet 21 is substantially aligned with the first and second fixed points A1, A2 of the housing 16, between these, the pair of scissors formed by this input and output lever 21 and the intermediate lever 22 is closed, the output lever 24 is engaged with the retaining lever 60, with, however, a slight play between its hook 71 and the hook 70 of the latter, and, under the stress of the elastic means 59, the finger 58 of this output lever 24 abuts against that of the ends of the light 88 of the reset button 85 which is closest to the input lever 20 to which is coupled this one.

    Conjointement, le pivot 50 que comporte le levier intermédiaire 22 pour l'articulation de la tirette de déclenchement 75 se trouve alors aligné avec le deuxième point fixe A2 du boítier 16.Jointly, the pivot 50 which the lever comprises intermediate 22 for the articulation of the pull tab trigger 75 is then aligned with the second point fixed A2 of the housing 16.

    Comme précédemment indiqué, l'enclenchement, c'est-à-dire le passage en état de fermeture de l'interrupteur différentiel 11, implique une action sur la manette 13 de celui-ci.As previously indicated, the engagement, that is to say the switch to the closed state of the switch differential 11, implies an action on the lever 13 of this one.

    Il résulte, de cette action, que le support de contacts que comporte cet interrupteur différentiel 11, et, donc, aussi, le levier d'entrée 20, qui lui est accouplé, de l'interface d'adaptation 10, sont entraínés en rotation autour du premier point fixe A1 du boítier 16, en pratique dans le sens anti-horaire, tel que schématisé par une flèche F1 sur les figures 5 et 6.It follows from this action that the support of contacts included in this differential switch 11, and, therefore, also, the input lever 20, which is coupled to it, of the adaptation interface 10, are rotated around of the first fixed point A1 of the housing 16, in practice in the counterclockwise, as shown by an arrow F1 on the Figures 5 and 6.

    Par le montage à boutonnière que constitue l'ergot 34 en prise avec l'encoche 32, le levier d'entrée 20 entraíne avec lui le levier intermédiaire 22, qui, par le pivot 36, entraíne à son tour avec lui le levier d'entrée et de sortie 21, en sorte que la paire de ciseaux que forment conjointement ce levier intermédiaire 22 et ce levier d'entrée et de sortie 21 reste fermée et que l'ensemble tourne d'un seul bloc autour du deuxième point fixe A2 du boítier 16, en pratique dans le sens anti-horaire, tel que schématisé par une flèche F2 sur la figure 6. By the buttonhole assembly that lugs 34 in engagement with the notch 32, the input lever 20 drives with him the intermediate lever 22, which, through the pivot 36, drives in turn with it the input and output lever 21, in so that the pair of scissors that jointly form this intermediate lever 22 and this input and output lever 21 stays closed and the whole unit rotates around the second fixed point A2 of the housing 16, in practice in the direction anti-clockwise, as shown by an arrow F2 on the figure 6.

    Conjointement, le levier d'entrée 20 entraíne aussi, dans le sens anti-horaire, le levier de basculement 92, suivant la flèche F2 de la figure 6.Jointly, the input lever 20 also drives, counterclockwise, the tilting lever 92, according to arrow F2 in FIG. 6.

    Il en résulte, par le bossage 105 de ce levier de basculement 92, une mise sous contrainte progressive des moyens élastiques 59.As a result, by the boss 105 of this lever tilting 92, a progressive stressing of the means elastic 59.

    Comme, conjointement, le levier d'entrée 20 entraíne, aussi, par le pivot 35, dans le sens anti-horaire, et tel que schématisé par une flèche F3 sur la figure 6, le poussoir de réarmement 85, le levier de sortie 24, ainsi libéré, tourne, dans le sens anti-horaire, sous la sollicitation des moyens élastiques 59, autour du troisième point fixe A3 du boítier 16, tel que schématisé par une flèche F4 sur la figure 6, ce qui conduit son crochet 71 à venir en prise avec le crochet 70 du levier de retenue 60, après absorption de la garde initiale entre ceux-ci.As, jointly, the input lever 20 drives, also, by pivot 35, counterclockwise, and such that shown diagrammatically by an arrow F3 in FIG. 6, the pusher of resetting 85, the release lever 24, thus released, turns, counterclockwise, under the demand of the means elastic 59, around the third fixed point A3 of the housing 16, as shown by an arrow F4 in Figure 6, which leads its hook 71 to come into engagement with the hook 70 of the retaining lever 60, after absorption of the initial guard between these.

    Sous la sollicitation des moyens élastiques 72, le levier de retenue 60 demeure, lui, en appui contre la butée 73 de la tirette de déclenchement 75, qui, elle, reste immobile, puisque le pivot 50 sur lequel elle est articulée est au droit du deuxième point fixe A2 du boítier 16 et reste ainsi fixe dans le mouvement de pivotement du levier intermédiaire 22 qui le porte.Under the stress of the elastic means 72, the retaining lever 60 remains in abutment against the stop 73 the trigger zipper 75, which remains stationary, since the pivot 50 on which it is articulated is on the right of the second fixed point A2 of the housing 16 and thus remains fixed in the pivoting movement of the intermediate lever 22 which The door.

    Conjointement, également, la fourchette 93 du levier de basculement 92 vient porter sur la lame 90 du moyen de commutation 89 et la sollicite en basculement en direction de celui des contacts fixes 91 qui est le plus éloigné de la manette 15.Also, fork 93 of the lever tilting 92 comes to bear on the blade 90 of the means switching 89 and requests it to tilt in the direction of that of the fixed contacts 91 which is furthest from the joystick 15.

    En pratique, le basculement de cette lame 90, qui, tel que décrit dans la demande de brevet européen No 0 650 178, implique le franchissement d'un point mort, et qui correspond au passage effectif en état de fermeture de l'interrupteur différentiel 11, par exemple pour la signalisation de celui-ci, se fait brusquement, tel que schématisé par une flèche F5 sur la figure 6, et il intervient avant que, comme représenté sur cette figure 6, la portion rectiligne 108 de la surface de came 106 du levier d'entrée 20 soit arrivée au bout du pan 109 oblique du bossage 98 du levier de basculement 92.In practice, the tilting of this blade 90, which, as as described in European patent application No. 0 650 178, implies the crossing of a neutral point, and which corresponds when the switch actually closes differential 11, for example for signaling thereof, is done suddenly, as shown by an arrow F5 on Figure 6, and it occurs before, as shown in this figure 6, the straight portion 108 of the cam surface 106 of the input lever 20 has reached the end of the pan 109 oblique of the boss 98 of the tilt lever 92.

    C'est donc après le basculement de la lame 90 du moyen de commutation 89 que, comme indiqué sur la figure 7, la surface de came 106 du levier d'entrée 20 vient agir par sa portion circulaire 107 sur le bossage 98 du levier de déclenchement 92, en portant alors sur ce bossage 98 par le pan 110, droit, de celui-ci.It is therefore after the tilting of the blade 90 of the means switch 89 that, as shown in Figure 7, the cam surface 106 of the input lever 20 acts by its circular portion 107 on the boss 98 of the lever trigger 92, while carrying on this boss 98 by the pan 110, right, of it.

    Il en résulte que le levier d'entrée 20 peut continuer à tourner, sans interférence sur la position du levier de basculement 92.As a result, the input lever 20 can continue to rotate, without interference on the position of the tilting 92.

    Il est possible, ainsi, de s'affranchir, avantageusement, pour le basculement de la lame 90 du moyen de commutation 89, de la position extrême du levier d'entrée 20 en fin de course, alors même que cette position extrême, imposée au levier d'entrée 20 par l'arbre du support de contacts que comporte l'interrupteur différentiel 11, peut, eu égard aux inévitables tolérances de fabrication, varier de manière non négligeable d'un interrupteur différentiel 11 à un autre.It is thus possible to free oneself, advantageously, for the tilting of the blade 90 of the means of switching 89, from the extreme position of the input lever 20 at the end of the race, even though this extreme position, imposed on the input lever 20 by the shaft of the support contacts of the differential switch 11, can, had due to inevitable manufacturing tolerances, vary from significant way from a differential switch 11 to a other.

    Dans ce qui précède, et pour les raisons précédemment indiquées, la manette 15 de l'interface d'adaptation 10, dûment entraínée par la manette 13 de l'interrupteur différentiel 11, a tourné, dans le sens anti-horaire, autour de son axe de rotation, ainsi qu'il ressort des figures 5, 6 et 7.In the above, and for the reasons above indicated, the handle 15 of the adaptation interface 10, duly driven by the handle 13 of the differential switch 11, has rotated counterclockwise around its axis of rotation, as shown in Figures 5, 6 and 7.

    Mais, ainsi qu'on l'aura noté, elle reste totalement neutre à l'égard du fonctionnement de cette interface d'adaptation 10.But, as we will have noted, it remains totally neutral with regard to the operation of this interface adaptation 10.

    Conjointement avec l'interrupteur différentiel 11, les auxiliaires électriques 12 se trouvent eux-mêmes enclenchés, le levier d'entrée et de sortie 21, qui suit le mouvement d'enclenchement correspondant, demeurant en prise, avec jeu, avec l'organe concerné de l'auxiliaire électrique 12 immédiatement adjacent, suivant la liaison mécanique L3.Together with the differential switch 11, the electrical auxiliaries 12 are themselves engaged, the input and output lever 21, which follows the movement corresponding engagement, remaining in engagement, with play, with the relevant member of the electrical auxiliary 12 immediately adjacent, following the mechanical link L3.

    Si, suivant le processus de déclenchement qui lui est propre, l'interrupteur différentiel 11 revient en état d'ouverture, un processus inverse de celui précédemment décrit se développe, qui ramène l'interface d'adaptation 10 dans sa configuration de repos représentée à la figure 5.If, according to the triggering process which is his clean, the differential switch 11 returns to its state opening, a process opposite to that previously described develops, which brings the adaptation interface 10 back into its rest configuration shown in Figure 5.

    Ce faisant, le levier d'entrée et de sortie 21 provoque, par la liaison mécanique L3, le déclenchement de l'auxiliaire électrique 12 immédiatement adjacent, et, par voie de conséquence, celui de l'auxiliaire électrique 12 suivant, et ainsi de suite, de proche en proche, d'un auxiliaire électrique 12 à un autre, lorsque plus de deux auxiliaires électriques 12 sont présents.In doing so, the input and output lever 21 causes, by the mechanical link L3, the triggering of the electrical auxiliary 12 immediately adjacent, and, by way consequently, that of the following electrical auxiliary 12, and so on, step by step, an auxiliary electric 12 to another, when more than two auxiliaries electrical 12 are present.

    On supposera maintenant que, partant de la configuration de repos, représentée à la figure 7, pour laquelle l'interrupteur différentiel 11 est en état de fermeture, l'un des auxiliaires électriques 12, et, par exemple, celui immédiatement adjacent à l'interface d'adaptation 10, est lui-même l'objet d'un déclenchement, suivant le processus qui lui est propre.We will now assume that, starting from the rest configuration, shown in Figure 7, for which the differential switch 11 is in the state of closure, one of the electrical auxiliaries 12, and, by example, the one immediately adjacent to the interface adaptation 10, is itself triggered, following its own process.

    Il résulte de ce déclenchement, par la liaison mécanique L3, que, après absorption d'une course réduite, qui est prévue pour tenir compte des inévitables tolérances de fabrication, et au cours de laquelle il ne se passe rien, le levier d'entrée et de sortie 21 de l'interface d'adaptation 10 est entraíné en rotation, en pratique dans le sens horaire, autour du deuxième point fixe A2 du boítier 16, tel que schématisé par une flèche F6 sur les figures 7 et 8.It results from this triggering, by the connection mechanical L3, that, after absorption of a reduced stroke, which is intended to take into account the inevitable tolerances of manufacturing, and during which nothing happens, the input and output lever 21 of the adaptation interface 10 is rotated, in practice clockwise, around the second fixed point A2 of the housing 16, such that shown schematically by an arrow F6 in Figures 7 and 8.

    Entraíné par le pivot 36 que porte ce levier d'entrée et de sortie 21, le levier intermédiaire 22, retenu par le levier d'entrée 20 du fait qu'il est en prise par son ergot 34 avec l'encoche 32 de celui-ci, pivote, dans le sens anti-horaire, autour de cet ergot 34, tel que schématisé par une flèche F7 sur la figure 8.Driven by pivot 36 carried by this input lever and output 21, the intermediate lever 22, retained by the input lever 20 because it is engaged by its lug 34 with the notch 32 thereof, pivots counterclockwise, around this lug 34, as shown schematically by a arrow F7 in Figure 8.

    Entraínée par ce levier intermédiaire 22, tel que schématisé par une flèche F8 sur la figure 8, la tirette de déclenchement 75 provoque à son tour le pivotement, dans le sens anti-horaire, du levier de retenue 60, autour du quatrième point fixe A4 du boítier 16, tel que schématisé par une flèche F9 sur la figure 8, ce qui libère le levier de sortie 24.Driven by this intermediate lever 22, such as shown diagrammatically by an arrow F8 in FIG. 8, the pull tab trigger 75 in turn causes pivoting, in the counterclockwise, retaining lever 60, around the fourth fixed point A4 of the housing 16, as shown schematically by an arrow F9 in FIG. 8, which releases the output lever 24.

    Sous la sollicitation des moyens élastiques 59, le levier de sortie 24 tourne, dans le sens anti-horaire, autour du troisième point fixe A3 du boítier 16, tel que schématisé par une flèche F10 sur la figure 8, ce qui, par son doigt 56 et la liaison mécanique L2 à laquelle appartient celui-ci, provoque le déclenchement de l'interrupteur différentiel 11, en fournissant à celui-ci, par l'apport ainsi fait des moyens élastiques 59, toute l'énergie nécessaire à ce déclenchement.Under the stress of elastic means 59, the exit lever 24 rotates counterclockwise around of the third fixed point A3 of the housing 16, as shown schematically by an arrow F10 in FIG. 8, which, by his finger 56 and the mechanical link L2 to which it belongs, triggers the differential switch 11, by providing it, by the contribution thus made means elastic 59, all the energy necessary for this triggering.

    Suivant le processus précédemment évoqué, le déclenchement de l'interrupteur différentiel 11 provoque à son tour celui des auxiliaires électriques 12.According to the process previously mentioned, the tripping of the differential switch 11 causes its turn that of the electrical auxiliaries 12.

    Il provoque, également, une rotation, dans le sens horaire, du levier d'entrée 20 de l'interface d'adaptation 10, autour du premier point fixe A1 du boítier 16, tel que schématisé par une flèche F11 sur la figure 9.It also causes a rotation, in the direction time, of the input lever 20 of the adaptation interface 10, around the first fixed point A1 of the housing 16, such that shown schematically by an arrow F11 in FIG. 9.

    Il en résulte, par le pivot 35 que porte ce levier d'entrée 20, un refoulement du poussoir de réarmement 85, tel que schématisé par une flèche F12 sur la figure 9.As a result, by the pivot 35 carried by this lever input 20, a discharge of the reset button 85, such shown schematically by an arrow F12 in FIG. 9.

    Sous l'action de ce poussoir de réarmement 85 avec lequel il est en prise par son doigt 58, le levier de sortie 24 tourne, alors, dans le sens horaire, autour du troisième point fixe A3 du boítier 16, tel que schématisé par une flèche F13 sur la figure 9, ce qui, moyennant un effacement élastique momentané du levier de retenue 60 à l'encontre des moyens élastiques 72, le conduit à venir à nouveau en prise avec ce levier de retenue 60, comme représenté sur la figure 5.Under the action of this reset button 85 with which he is engaged by his finger 58, the exit lever 24 then turns clockwise around the third fixed point A3 of the housing 16, as shown schematically by an arrow F13 in FIG. 9, which, by means of an elastic erasure momentary of the retaining lever 60 against the means elastic 72, the conduit to again come into engagement with this retaining lever 60, as shown in FIG. 5.

    Ainsi, l'interrupteur différentiel 11 assure, par lui-même, lors de son déclenchement, le réarmement de l'interface d'adaptation 10 suivant l'invention.Thus, the differential switch 11 ensures, by itself, when triggered, interface reset adaptation 10 according to the invention.

    Comme précédemment, la manette 15 de cette interface d'adaptation 10 reste neutre dans le processus correspondant.As before, the controller 15 of this interface adaptation 10 remains neutral in the corresponding process.

    Conjointement, le levier de basculement 92 demeure d'abord immobile, le temps que, par sa portion circulaire 107, la surface de came 106 du levier d'entrée 20 reste au contact du pan 110 droit de son bossage 98, ce qui assure avantageusement un maintien temporaire de la lame 90 du moyen de commutation 89 dans la position qui est la sienne pour l'état de fermeture de l'interrupteur différentiel 11. At the same time, the tilt lever 92 remains first motionless, the time that, by its circular portion 107, the cam surface 106 of the input lever 20 remains in contact of the right pan 110 of its boss 98, which ensures advantageously a temporary holding of the blade 90 of the means switching 89 in the position that is hers for the closing state of the differential switch 11.

    Ce n'est que dans un deuxième temps que, après franchissement du point d'équilibre correspondant, le levier de basculement 92 se trouve libéré, son bossage 98 passant sous la surface de came 106 du levier d'entrée 20, en portant par son pan 109 oblique contre la portion rectiligne 108 de celle-ci.It was only afterwards that after crossing of the corresponding equilibrium point, the lever tilting 92 is released, its boss 98 passing under the cam surface 106 of the input lever 20, bearing by its side 109 oblique against the straight portion 108 of this one.

    Une fois ainsi libéré, le levier de basculement 92 assure le retour de la lame 90 du moyen de commutation 89 à sa position initiale, comme représenté.Once released, the tilt lever 92 ensures the return of the blade 90 of the switching means 89 to its initial position, as shown.

    En pratique, le levier de basculement 92 intervient alors sous la seule sollicitation des moyens élastiques 59, qui se détendent, sans prélèvement d'énergie, dans l'interrupteur différentiel 11.In practice, the tilting lever 92 intervenes then under the sole solicitation of the elastic means 59, which relax, without taking any energy, in the switch differential 11.
