Description

La présente invention concerne d'une manière générale les appareils électriques du genre comportant, dans un boítier, un poussoir, qui, d'une part, est monté mobile entre deux positions, l'une déployée, l'autre rétractée, sous le contrôle d'un bouton de commande à la disposition de l'usager, et qui, d'autre part, est soumis à des moyens élastiques de rappel le sollicitant en permanence en direction de sa position déployée.The present invention relates generally electrical appliances of the kind comprising, in a housing, a pusher, which, on the one hand, is mounted movable between two positions, one deployed, the other retracted, under control a command button available to the user, and who, on the other hand, is subjected to elastic return means the permanently soliciting towards its deployed position.

Il peut s'agir par exemple d'un simple contacteur destiné à permettre la commande à distance d'un quelconque télérupteur.It can for example be a simple contactor intended to allow the remote control of any remote control switch.

Pour certaines applications, seule doit être stable la position déployée du poussoir, celui-ci abandonnant alors systématiquement sa position rétractée lorsqu'il est cessé d'agir sur son bouton de commande, cependant que, pour d'autres applications, cette position rétractée doit elle aussi être une position stable, le poussoir devant rester de lui-même dans cette position rétractée, ou, plus précisément, dans une position rétractée de service proche de celle-ci, lorsque, après l'action sur le bouton de commande l'ayant conduit à cette position rétractée, il est cessé d'agir sur ce bouton de commande.For some applications, only the deployed position of the pusher, the latter then giving up systematically retracted position when stopped to act on its command button, however that for others applications, this retracted position must also be a stable position, the pusher must remain by itself in this retracted position, or, more precisely, in a service retracted position close to this, when, after the action on the command button having led it to this retracted position, it is stopped acting on this button ordered.

Il est donc normalement nécessaire de disposer de deux appareils électriques différents, au prix d'une duplication dispendieuse des fabrications correspondantes.It is therefore normally necessary to have two different electrical appliances, at the cost of a duplication expensive to manufacture.

Il a cependant été proposé d'équiper ces appareils électriques d'un sélecteur, qui est accessible de l'extérieur du boítier à l'usager, et qui est lui aussi monté mobile entre deux positions, l'une de non-ingérence, pour laquelle il laisse le poussoir se débattre librement entre ses deux positions, l'autre d'ingérence, pour laquelle, au contraire, il le maintient de manière débrayable en position rétractée, avec, intervenant alors pour ce faire entre le poussoir et le sélecteur, des moyens d'accrochage et un ergot d'accrochage apte à coopérer en retenue avec ces moyens d'accrochage.It has however been proposed to equip these devices electric from a selector, which is accessible from the outside from the housing to the user, and which is also mounted mobile between two positions, one of non-interference, for which it leaves the pusher struggles freely between its two positions, the other of interference, for which, on the contrary, it keeps disengageably in the retracted position, with, then intervening to do this between the pusher and the selector, hooking means and a hooking lug able to cooperate in restraint with these attachment means.

C'est le cas dans le document FR-A-2 322 442, et c'est le cas, également, dans le document EP-A-0 040 130. This is the case in document FR-A-2 322 442, and it is the case, also, in document EP-A-0 040 130.

Suivant l'application envisagée, il suffit à l'usager de placer le sélecteur dans l'une ou l'autre de ses positions.Depending on the application envisaged, it suffices for the user to place the selector in one or other of its positions.

Dès lors, une seule fabrication suffit, au bénéfice des coûts.Therefore, a single production is sufficient, for the benefit of costs.

Tant dans le cas du document FR-A-2 322 442 que dans le cas du document EP-A-0 040 130, le sélecteur est porté par le boítier, en étant en pratique monté pivotant sur celui-ci, tandis que l'ergot d'accrochage est porté par le sélecteur, en étant en pratique rigidement assujetti à ce dernier.Both in the case of document FR-A-2 322 442 and in in the case of document EP-A-0 040 130, the selector is carried by the housing, being in practice pivotally mounted thereon, while the hooking lug is carried by the selector, in being in practice rigidly subject to the latter.

Dans le document FR-A-2 322 442, le sélecteur ne débouche pas à l'extérieur du boítier, et l'usager n'y a accès qu'à travers une ouverture, nécessairement étroite, car en forme de fente, de celui-ci.In document FR-A-2 322 442, the selector does not does not open outside the housing, and the user does not have access to it that through an opening, necessarily narrow, because in slit shape, of it.

Pour changer la position du sélecteur, il faut enfiler un outil à travers cette ouverture, et faire passer à l'aide de celui-ci le sélecteur au-dessus d'une nervure du poussoir.To change the position of the selector, press a tool through this opening, and pass it using of it the selector above a rib of the pusher.

La manipulation correspondante est particulièrement délicate à conduire, et il en est d'autant plus ainsi qu'elle se réalise en pratique quasiment en aveugle.The corresponding handling is particularly tricky to drive, and this is all the more so as it is practically carried out almost blind.

Dans le document EP-A-0 040 130, le sélecteur fait saillie hors du boítier.In document EP-A-0 040 130, the selector makes protruding out of the housing.

Mais son changement de position ne peut intervenir que pour la position rétractée, c'est-à-dire enfoncée, du poussoir.But his change of position can only occur for the retracted, that is to say, depressed, position of the pusher.

La manipulation est là encore malaisée à conduire, dans la mesure où elle nécessite simultanément une action sur le poussoir et une action sur le sélecteur.The manipulation is again difficult to drive, in since it simultaneously requires action on the push button and action on the selector.

En outre, si le poussoir n'est pas en position suffisamment enfoncée, il peut en résulter intempestivement des erreurs de manoeuvre.In addition, if the pusher is not in position pressed down enough, it may inadvertently result in maneuvering errors.

Enfin, tant dans le document EP-A-0 040 130 que dans le document FR-A-2 322 442, le sélecteur ne demeure pas fixe lors de l'action sur le poussoir.Finally, both in document EP-A-0 040 130 and in document FR-A-2 322 442, the selector does not remain fixed during the action on the pusher.

Au contraire, qu'il soit en position d'ingérence ou en position de non-ingérence, il est alors l'objet d'une certaine oscillation, et, notamment dans le cas du document EP-A-0 040 130, il peut en résulter des dysfonctionnements, par passage intempestif d'une position à une autre. On the contrary, whether it is in an interference position or in non-interference position it is then subject to some oscillation, and, in particular in the case of the document EP-A-0 040 130, it may result in malfunctions, for example inadvertent passage from one position to another.

La présente invention a d'une manière générale pour objet une disposition permettant d'éviter ces inconvénients.The present invention generally has for subject a provision to avoid these drawbacks.

De manière plus précise, elle a pour objet un appareil électrique du genre à poussoir et sélecteur concerné et caractérisé d'une manière générale en ce que les moyens d'accrochage sont portés par le sélecteur tandis que l'ergot d'accrochage est porté par le poussoir.More specifically, it relates to a device electric of the push-button type and selector concerned and generally characterized in that the means hooks are carried by the selector while the lug hooking is carried by the pusher.

Grâce à une telle disposition, le changement de position du sélecteur peut avantageusement se faire pour la position déployée, de repos, du poussoir, sans intervention concomitante sur celui-ci.Thanks to such an arrangement, the change of position of the selector can advantageously be done for the extended position, rest, pusher, no intervention concomitant on this one.

La manipulation correspondante s'en trouve grandement facilitée et il n'y a aucun risque de fausse manoeuvre.The corresponding manipulation is greatly facilitated and there is no risk of false operation.

En outre, dans l'une et l'autre de ses positions, le sélecteur demeure avantageusement fixe lorsqu'il est agi sur le poussoir, au bénéfice d'une plus grande sûreté de fonctionnement pour l'ensemble.In addition, in either position, the the selector advantageously remains fixed when it is operated on the pusher, for the benefit of greater safety functioning for the whole.

Préférentiellement, le sélecteur comporte, en sus des moyens d'accrochage, des moyens de liberté neutres à l'égard du poussoir.Preferably, the selector comprises, in addition to the means of attachment, means of freedom neutral with regard to of the pusher.

Ainsi, suivant sa position, il interpose, sans ambiguïté, sur le trajet du poussoir, soit les moyens d'accrochage, soit les moyens de liberté, ce qui conforte encore la sûreté de fonctionnement de l'ensemble.Thus, depending on its position, it interposes, without ambiguity, on the path of the pusher, that is the means attachment, or the means of freedom, which comfort still the operational safety of the whole.

Enfin, suivant une forme de réalisation possible, mais non impérative, de réalisation, le sélecteur est monté rotatif, et, pour sa commande en rotation, il comporte un moyeu, qui, accessible de l'extérieur du boítier à la faveur d'un évidement de celui-ci, présente diamétralement une saignée, à la manière de la tête d'une vis.Finally, according to a possible embodiment, but non-imperative, for implementation, the selector is rotatably mounted, and, for its rotation control, it comprises a hub, which, accessible from outside the housing through a recess of it, diametrically has a groove, in the manner of the head of a screw.

Pour son changement de position, il suffit donc d'agir sur ce moyeu à l'aide d'un tournevis ou d'une pièce de monnaie.For its change of position, it suffices to act on this hub using a screwdriver or a coin.

La manipulation correspondante est avantageusement très aisée, et, se faisant de manière franche, pour la position de repos du poussoir, qui correspond en pratique à la configuration de livraison de l'appareil électrique, elle n'est avantageusement pas susceptible de conduire à une quelconque erreur d'aiguillage pour ce poussoir.The corresponding handling is advantageously very easy, and, being frank, for the position of rest of the pusher, which in practice corresponds to the delivery configuration of the electrical appliance, it is not advantageously not likely to lead to any referral error for this pusher.

Les caractéristiques et avantages de l'invention ressortiront d'ailleurs de la description qui va suivre, à titre d'exemple, en référence aux dessins schématiques annexés sur lesquels :

  • la figure 1 est une vue en perspective d'un appareil électrique suivant l'invention ;
  • la figure 2 est, à échelle supérieure, une vue en perspective éclatée se rapportant pour l'essentiel au poussoir que comporte cet appareil électrique et au sélecteur qui lui est associé suivant l'invention ;
  • la figure 3 est, à échelle encore supérieure, une vue en perspective de ce seul sélecteur, représenté isolément, suivant la flèche III de la figure 2 ;
  • la figure 4A est, suivant cette même flèche III, une vue partielle en élévation de l'ensemble, pour une première position du sélecteur ;
  • la figure 4B est une vue partielle en élévation analogue à celle de la figure 4A, pour la deuxième position du sélecteur.
    • The characteristics and advantages of the invention will become apparent from the description which follows, by way of example, with reference to the appended schematic drawings in which:
  • Figure 1 is a perspective view of an electrical device according to the invention;
  • Figure 2 is, on a larger scale, an exploded perspective view relating essentially to the pusher that includes this electrical device and the selector associated with it according to the invention;
  • Figure 3 is, on a still larger scale, a perspective view of this single selector, shown in isolation, according to arrow III of Figure 2;
  • FIG. 4A is, along this same arrow III, a partial elevation view of the assembly, for a first position of the selector;
  • FIG. 4B is a partial view in elevation similar to that of FIG. 4A, for the second position of the selector.

    • Ces figures illustrent, à titre d'exemple, l'application de l'invention à un appareil électrique 10 modulaire, c'est-à-dire à un appareil électrique 10 dont le boítier 11 se présente sous la forme générale d'une plaquette d'épaisseur multiple d'un module déterminé, ce qui lui permet d'être si nécessaire disposé côte à côte sur un même support avec d'autres appareils électriques 10 modulaires de même type.These figures illustrate, by way of example, application of the invention to an electrical appliance 10 modular, that is to say an electrical device 10 whose housing 11 is in the general form of a plate multiple thickness of a given module, which allows it to be placed side by side on the same support if necessary with other modular electrical appliances of the same type.

    Dans la forme de réalisation représentée, le boítier 11 est formé d'un corps 11A et d'un flasque de fermeture 11B, mais, en variante il peut tout aussi bien être formé de deux coquilles, d'importances sensiblement égales, et convenablement affrontées et solidarisées l'une à l'autre.In the embodiment shown, the housing 11 is formed by a body 11A and a closing flange 11B, but, as a variant, it can just as easily be formed of two shells, of substantially equal importance, and suitably confronted and united to each other.

    Quoi qu'il en soit, le boítier 11 présente, sur sa tranche, sur deux faces latérales opposées de celle-ci, un ou plusieurs évidements 12 pour donner accès aux bornes de connexion nécessaires à la desserte de l'appareil électrique 10. Anyway, the housing 11 presents, on its edge, on two opposite side faces thereof, one or several recesses 12 to give access to the terminals of connection required to service the electrical appliance 10.

    Dans la forme de réalisation représentée, il y a ainsi deux évidements 12 par face latérale de la tranche du boítier 11.In the embodiment shown, there are thus two recesses 12 per side face of the edge of the housing 11.

    Les dispositions qui précèdent sont bien connues par elle-mêmes, et, ne relevant pas de la présente invention, elle ne seront pas décrites plus en détail ici.The foregoing provisions are well known by themselves, and, not falling within the scope of the present invention, it will not be described in more detail here.

    C'est de surcroít la raison pour laquelle, sur les figures, le boítier 11 n'a été pour l'essentiel que schématisé par son contour.This is also the reason why, on the figures, the housing 11 was essentially only schematized by its outline.

    De même, l'appareil électrique 10, pris dans son ensemble, ne sera pas décrit dans tous ses détails ici.Similarly, the electrical appliance 10, taken in its together will not be described in full detail here.

    Seuls en seront décrits les éléments nécessaires à la compréhension de l'invention.Only the elements necessary for the understanding of the invention.

    Il suffira à cet égard d'indiquer que cet appareil électrique 10 comporte, dans le boítier 11, un poussoir 14, qui, d'une part, est monté mobile entre deux positions, l'une déployée, l'autre rétractée, sous le contrôle d'un bouton de commande 15 à la disposition de l'usager, et qui, d'autre part, est soumis à des moyens élastiques de rappel 13 le sollicitant en permanence en direction de sa position déployée, cette position déployée constituant ainsi en pratique une position de repos pour l'ensemble.It will suffice in this regard to indicate that this device electric 10 comprises, in the housing 11, a pusher 14, which, on the one hand, is mounted movable between two positions, one deployed, the other retracted, under the control of a button command 15 available to the user, and who, on the other hand, is subjected to elastic return means 13 urging it continuously towards its deployed position, this deployed position thus constituting in practice a position rest for the whole.

    En pratique, le poussoir 14 forme un tiroir monté coulissant dans le boítier 11, et il est convenablement guidé en translation dans celui-ci.In practice, the pusher 14 forms a mounted drawer sliding in the housing 11, and it is properly guided in translation in this one.

    Dans la forme de réalisation représentée, ce poussoir 14 a globalement un contour parallélépipédique, allongé dans le sens de la hauteur du boítier 11, perpendiculairement aux faces supérieure et inférieure de la tranche de celui-ci, et le bouton de commande 15 en est solidaire.In the embodiment shown, this pusher 14 generally has a parallelepipedic outline, elongated in the direction of the height of the housing 11, perpendicular to the upper and lower sides of the edge thereof, and the control button 15 is integral with it.

    Sa direction de trajet T dans le boítier 11, schématisée en traits interrompus sur les figures 1, 2, 4A et 4B, est elle aussi perpendiculaire aux faces supérieure et inférieure de la tranche du boítier 11.Its direction of travel T in the housing 11, shown schematically in broken lines in Figures 1, 2, 4A and 4B, is also perpendicular to the upper faces and lower edge of the housing 11.

    En pratique, le bouton de commande 15 s'étend suivant cette direction de trajet T. In practice, the control button 15 extends along this direction of travel T.

    Il fait donc saillie sur la face transversale supérieure du poussoir 14.It therefore protrudes from the transverse face upper pusher 14.

    Pour la position déployée du poussoir 14, le bouton de commande 15 fait largement saillie sur la face supérieure de la tranche du boítier 11, tel que représenté en traits continus sur les figures 4A et 4B.For the deployed position of the pusher 14, the button command 15 protrudes widely from the upper side of the edge of the housing 11, as shown in solid lines in Figures 4A and 4B.

    Pour la position rétractée du poussoir 14, il est au contraire plus ou moins enfoncé dans le boítier 11, tel que schématisé en traits interrompus sur la seule figure 4A.For the retracted position of the pusher 14, it is at more or less pressed into the housing 11, such as shown schematically in broken lines in FIG. 4A alone.

    Conjointement, dans la forme de réalisation représentée, et tel que schématisé sur la figure 2, les moyens élastiques de rappel 13 associés au poussoir 14 sont par exemple constitués par un simple ressort de compression, du type ressort à boudin, qui, prenant appui sur le boítier 11, porte sur le poussoir 14 du côté de celui-ci opposé à son bouton de commande 15, et, donc, sur la face transversale inférieure de ce poussoir 14.Jointly, in the embodiment shown, and as shown schematically in Figure 2, the means return elastic 13 associated with pusher 14 are by example consisting of a simple compression spring, coil spring type, which, bearing on the housing 11, door on the pusher 14 on the side thereof opposite its control button 15, and therefore on the transverse face bottom of this pusher 14.

    Pour la définition de sa position déployée, le poussoir 14 comporte, transversalement, sur l'une au moins de ses faces latérales, dans la forme de réalisation représentée, un épaulement 16 par lequel il est apte à venir en butée contre un cran 17 prévu à cet effet sur le flasque de fermeture 11B du boítier 11.For the definition of its deployed position, the pusher 14 has, transversely, on at least one of its faces side, in the embodiment shown, a shoulder 16 by which it is able to abut against a notch 17 provided for this purpose on the closing flange 11B of the housing 11.

    Sur la figure 2, seuls sont visibles, d'une part, l'épaulement 16 de l'une des faces latérales du poussoir 14, et, d'autre part, le cran 17 du boítier 11 correspondant à l'autre de ces faces latérales.On FIG. 2, only visible, on the one hand, the shoulder 16 of one of the lateral faces of the pusher 14, and, on the other hand, the notch 17 of the housing 11 corresponding to the other of these side faces.

    L'appareil électrique 10 est par exemple un simple contacteur.The electrical appliance 10 is for example a simple contactor.

    Tel que schématisé à la figure 2, le poussoir 14 pilote à cet effet un contact mobile 18 susceptible d'établir une liaison entre deux contacts fixes 19 que des conducteurs 20 relient chacun respectivement à des bornes de connexion opposées non représentées.As shown in Figure 2, the pusher 14 controls for this purpose a mobile contact 18 capable of establishing a connection between two fixed contacts 19 as conductors 20 each connect respectively to connection terminals opposite not shown.

    Par exemple, le poussoir 14 comporte un évidement 21, dans lequel le contact mobile 18 se trouve disposé sous le contrôle de moyens élastiques, non représentés, susceptibles de le maintenir en appui contre les contacts fixes 19, avec l'effort d'appui nécessaire, lorsque, entraíné par le poussoir 14, il est venu en butée contre ces contacts fixes 19.For example, the pusher 14 has a recess 21, in which the movable contact 18 is located under the control of elastic means, not shown, susceptible to keep it in abutment against the fixed contacts 19, with the support force required when, driven by the pusher 14, it has come into abutment against these fixed contacts 19.

    Dans la forme de réalisation représentée, le poussoir 14 présente dos à dos, avec un certain décalage, deux évidements 21, pour le cas où, comme il ressort de ce qui précède, il y a deux bornes de connexion sur chacune des faces latérales de la tranche du boítier 11, et, donc, deux contacts mobiles 18 à commander en parallèle.In the embodiment shown, the pusher 14 back to back, with some offset, two recesses 21, in case, as it appears from what above, there are two connection terminals on each side sides of the edge of the housing 11, and therefore two contacts mobile 18 to be controlled in parallel.

    L'appareil électrique 10 suivant l'invention est équipé d'un sélecteur 22, qui est accessible à l'usager de l'extérieur du boítier 11, et qui est lui aussi monté mobile entre deux positions, l'une de non-ingérence, figure 4B, pour laquelle il laisse le poussoir 14 se débattre librement entre ses deux positions, l'autre d'ingérence, figure 4A, pour laquelle, au contraire, et suivant des dispositions décrites plus en détail ultérieurement, il le maintient de manière débrayable en position rétractée, avec, intervenant alors pour ce faire entre le poussoir 14 et le sélecteur 22, des moyens d'accrochage 23 et un ergot d'accrochage 34 apte à coopérer en retenue ave ces moyens d'accrochage 23.The electrical device 10 according to the invention is equipped a selector 22, which is accessible to the user from the outside of the housing 11, and which is also mounted movable between two positions, one of non-interference, Figure 4B, for which it let the pusher 14 struggle freely between its two positions, the other of interference, Figure 4A, for which, at otherwise, and according to arrangements described in more detail later, it keeps it disengageably in retracted position, with, then intervening to do this between the pusher 14 and the selector 22, hooking means 23 and a hooking lug 34 able to cooperate in retaining with these attachment means 23.

    Suivant l'invention, les moyens d'accrochage 23 sont portés par le sélecteur 22 tandis que l'ergot d'accrochage 34 est porté par le poussoir 14.According to the invention, the attachment means 23 are carried by the selector 22 while the latching lug 34 is carried by the pusher 14.

    Dans la forme de réalisation représentée, le sélecteur 22 est monté rotatif dans le boítier 11, autour d'un axe A orthogonal à la direction de trajet T du poussoir 14, et il comporte, à distance, angulairement, des moyens d'accrochage 23, des moyens de liberté 24 neutres à l'égard du poussoir 14.In the embodiment shown, the selector 22 is rotatably mounted in the housing 11, about an axis A orthogonal to the direction of travel T of the pusher 14, and it includes, at a distance, angularly, hooking means 23, means of freedom 24 neutral with respect to the pusher 14.

    En pratique, le sélecteur 22 se présente sous la forme générale d'un disque de contour circulaire, qui est au moins pour partie enchâssé, à rotation, dans un logement 25 de contour circulaire complémentaire prévu à cet effet dans le boítier 11, en regard du poussoir 14, et sur une même face duquel, en pratique celle tournée vers le poussoir 14, sont formés les moyens d'accrochage 23 et de liberté 24 associés à ce poussoir 14. In practice, the selector 22 is in the form general of a circular contour disc, which is at least partly embedded, in rotation, in a housing 25 of additional circular outline provided for this purpose in the housing 11, opposite the pusher 14, and on the same face which, in practice that facing the pusher 14, are formed the attachment means 23 and freedom 24 associated with this pusher 14.

    Sur l'autre face de ce disque, le sélecteur 22 comporte, axialement en saillie, pour sa commande en rotation, un moyeu 26, qui fait surface sur l'une des faces principales du boítier 11, à la faveur d'un évidement 28 de celui-ci, figure 1, et qui est ainsi à la disposition de l'usager.On the other side of this disc, the selector 22 comprises, axially projecting, for its rotation control, a hub 26, which surfaces on one of the main faces of the housing 11, by means of a recess 28 thereof, Figure 1, and which is thus available to the user.

    En pratique, ce moyeu 26 s'étend au mieux à ras avec la face principale du boítier 11 sur laquelle il débouche, pour ne pas faire saillie sur celle-ci, et, pour en faciliter la commande en rotation, il présente diamétralement une saignée 29, à la manière de la tête d'une vis.In practice, this hub 26 extends at best flush with the main face of the housing 11 on which it opens, for do not protrude thereon, and, to facilitate its rotational control, it has diametrically a groove 29, like the head of a screw.

    En pratique, également, ce moyeu 26 présente, radialement en saillie, à son extrémité libre, deux lamelles 30, figure 2, qui, disposées en positions diamétralement opposées l'une par rapport à l'autre, viennent s'encliqueter, pour son maintien, dans un lamage 31 prévu annulairement à cet effet au débouché de l'évidement 28 du boítier 11, figure 1, après leur passage en force dans cet évidement 28.In practice, too, this hub 26 has, radially projecting, at its free end, two strips 30, figure 2, which, arranged in diametrically positions opposite one another, snap into place, for its maintenance, in a counterbore 31 provided annularly thereon effect at the outlet of the recess 28 of the housing 11, FIG. 1, after their passage in force in this recess 28.

    Dans la forme de réalisation représentée, les moyens d'accrochage 23 que forme le sélecteur 22 sont des moyens de came du genre came en coeur.In the embodiment shown, the means attachment 23 formed by the selector 22 are means of cam of the heart-like kind.

    Pour coopération avec de tels moyens de came, le poussoir 14 comporte, transversalement par rapport à sa direction de trajet T, une rainure 32 dans laquelle se débat l'ergot d'accrochage 34.For cooperation with such cam means, the pusher 14 comprises, transversely relative to its direction of travel T, a groove 32 in which struggles the lug 34.

    Dans le fond de la rainure 32 peuvent être prévus, si désiré, des moyens élastiques, non représentés, propres à solliciter l'ergot d'accrochage 34 en direction du sélecteur 22.In the bottom of the groove 32 can be provided, if desired, elastic means, not shown, suitable for press the latching pin 34 towards the selector 22.

    Dans la forme de réalisation représentée, l'ergot d'accrochage 34, qui est globalement cylindrique, est épaulé, et il présente ainsi, d'une part, un tronçon de plus grand diamètre 34', par lequel il est en prise avec la rainure 32 du poussoir 14, et, d'autre part, un tronçon de plus petit diamètre 34'', par lequel il est apte à coopérer avec les moyens de came que forment les moyens d'accrochage 23 associés.In the embodiment shown, the lug attachment 34, which is generally cylindrical, is supported, and it thus presents, on the one hand, a larger section diameter 34 ', by which it engages the groove 32 of the pusher 14, and, on the other hand, a smaller section diameter 34 '', by which it is able to cooperate with the means cam formed by the associated attachment means 23.

    En pratique, ces moyens de came comportent, dans une cavité 36 que présente en creux le sélecteur 22 et qui est propre également au débattement de l'ergot d'accrochage 34 du poussoir 14, d'une part, un ílot 37, en forme de coeur, qui est interposé sur le trajet de cet ergot d'accrochage 34, et dont la pointe 38 est, en position d'ingérence, dirigée vers la position déployée du poussoir 14, c'est-à-dire vers le bouton de commande 15 de celui-ci, tandis que sa dépression 39 est dirigée en sens opposé, et, d'autre part, un ensemble de rampes 40, 41, 42, précisées ci-après, qui sont aptes à alternativement diriger l'ergot d'accrochage 34 du poussoir 14 vers la dépression 39 de l'ílot 37 lorsque, amené en position rétractée, le poussoir 14 est relâché, et à écarter cet ergot d'accrochage 34 de cet ílot 37 lorsque, le poussoir 14 étant ainsi en position rétractée, il est à nouveau agi sur son bouton de commande 15.In practice, these cam means comprise, in a cavity 36 which the selector 22 has in hollow and which is also suitable for the travel of the hooking lug 34 of the pusher 14, on the one hand, an island 37, in the shape of a heart, which is interposed on the path of this latching lug 34, and of which the tip 38 is, in the interference position, directed towards the deployed position of pusher 14, i.e. towards the button control 15 thereof, while its depression 39 is directed in opposite direction, and, on the other hand, a set of ramps 40, 41, 42, specified below, which are suitable for alternately direct the hooking lug 34 of the pusher 14 towards depression 39 of island 37 when brought into position retracted, the pusher 14 is released, and to spread this lug attachment 34 of this island 37 when, the pusher 14 being thus in the retracted position, it is again acted on its control button 15.

    L'ílot 37 s'étend en bordure immédiate du sélecteur 22, avec, en pratique, sa pointe 38 au ras avec le contour de celui-ci.Island 37 extends at the immediate edge of selector 22, with, in practice, its tip 38 flush with the outline of this one.

    De part et d'autre de l'ílot 37, la cavité 36 définit, parallèlement à la direction de trajet T du poussoir 14, d'une part, une entrée E, et, d'autre part, une sortie S, et, lorsque le sélecteur 22 est en position d'ingérence, cette cavité 36 se trouve être dans le prolongement d'une cavité 44, qui est formée dans le boítier 11, et avec laquelle est en prise, par son tronçon de plus petit diamètre 34'', l'ergot d'accrochage 34 du poussoir 14.On either side of the island 37, the cavity 36 defines, parallel to the direction of travel T of the pusher 14, of a on the one hand, an input E, and, on the other hand, an output S, and, when the selector 22 is in the interference position, this cavity 36 happens to be in the extension of a cavity 44, which is formed in the housing 11, and with which it is engaged, by its section of smaller diameter 34 '', the hooking lug 34 of pusher 14.

    Les flancs de cette cavité 44 forment un dièdre centré sur la direction de trajet T du poussoir 14, en sorte que, pour la position déployée de celui-ci, et tel que représenté à la figure 4A, l'ergot d'accrochage 34 se trouve lui-même systématiquement centré sur cette direction de trajet T.The sides of this cavity 44 form a centered dihedral on the path direction T of the pusher 14, so that, for the deployed position of it, and as shown in the FIG. 4A, the hooking lug 34 is located itself systematically centered on this direction of travel T.

    Par contre, la pointe 38 de l'ílot 37 se trouve décalée transversalement du côté de la sortie S par rapport à la direction de trajet T du poussoir 14.On the other hand, the tip 38 of the island 37 is offset transversely on the side of the outlet S with respect to the direction of travel T of pusher 14.

    La rampe 40 appartient au contour de la cavité 36.The ramp 40 belongs to the contour of the cavity 36.

    Elle s'étend en oblique par rapport à la direction de trajet T, au-delà de l'ílot 37, en formant l'un des flancs d'un lobe 46 de la cavité 36 situé dans le prolongement de l'entrée E.It extends obliquely to the direction of path T, beyond island 37, forming one of the sides of a lobe 46 of cavity 36 located in the extension of the entrance E.

    La dépression 39 de l'ílot 37 est globalement centrée sur la direction de trajet T du poussoir 14.The depression 39 of the island 37 is generally centered on the direction of travel T of the pusher 14.

    La rampe 41 forme celui des flancs de cette dépression 39 qui est du côté de l'entrée E.The ramp 41 forms that of the sides of this depression 39 which is on the entrance side E.

    Elle s'étend au droit du lobe 46 de la cavité 36.It extends to the right of the lobe 46 of the cavity 36.

    La rampe 42, enfin, appartient, comme la rampe 40, au contour de la cavité 36.Ramp 42, finally, belongs, like ramp 40, to contour of the cavity 36.

    Elle s'étend en oblique de part et d'autre de la direction de trajet T du poussoir 14, en regard de la dépression 39 de l'ílot 37, et elle conduit à un lobe 47 de la cavité 36 situé dans le prolongement de la sortie S.It extends obliquely on either side of the direction of travel T of pusher 14, facing the depression 39 of island 37, and it leads to a lobe 47 of the cavity 36 located in the extension of exit S.

    Il résulte de ce qui précède que si, le poussoir 14 étant en position déployée, tel que représenté en trait continu sur la figure 4A pour son ergot d'accrochage 34, il est exercé une action d'enfoncement sur son bouton de commande 15, suivant la flèche F1 de la figure 1, l'ergot d'accrochage 34 est dirigé par l'ílot 37 sur l'entrée E, suivant la flèche F2 de la figure 4A, puis, par la rampe 40, sur le lobe 46 de la cavité 36.It follows from the above that if, the pusher 14 being in the deployed position, as shown in solid lines in FIG. 4A, for its hooking lug 34, it is exerted a pressing action on its control button 15, according to the arrow F1 in FIG. 1, the hooking lug 34 is directed by island 37 on entry E, following arrow F2 in the figure 4A, then, by the ramp 40, on the lobe 46 of the cavity 36.

    Le poussoir 14 est dès lors dans une position rétractée, qui n'est pas exactement sa position rétractée de service, mais qui est légèrement au-delà de celle-ci.The pusher 14 is therefore in a position retracted, which is not exactly its retracted position from service, but that is slightly beyond it.

    Si l'action d'enfoncement exercée jusque-là sur le bouton de commande 15 est relâchée, le poussoir 14 a tendance à revenir à sa position déployée, sous la sollicitation des moyens élastiques de rappel 13 qui lui sont associés.If the driving action exerted so far on the control button 15 is released, push-button 14 tends to return to its deployed position, under the solicitation of elastic return means 13 associated therewith.

    Mais, compte tenu de ce qui précède, son ergot d'accrochage 34, et, plus précisément, le tronçon de plus petit diamètre 34'' de celui-ci, interfère alors, dans son trajet, avec la rampe 41 de l'ílot 37, jusqu'à venir au centre de la dépression 39 de celui-ci, tel que schématisé en traits interrompus sur la figure 4A.But, in view of the above, its lug attachment 34, and, more precisely, the section of smaller diameter 34 '' of it, then interferes, in its path, with ramp 41 of island 37, until you come to the center of the depression 39 of it, as shown in lines interrupted in Figure 4A.

    Le poussoir 14 est alors maintenu accroché en position rétractée de service.The pusher 14 is then kept hooked in position retracted from service.

    Si une nouvelle action d'enfoncement est exercée sur le bouton de commande 15, suivant la flèche F1 de la figure 4A, l'ergot d'accrochage 34 du poussoir 14 interfère avec la rampe 42 et il est dirigé par celle-ci vers le lobe 47 de la cavité 36 situé dans le prolongement de la sortie S.If a new driving action is exercised on the control button 15, along the arrow F1 in FIG. 4A, the latching lug 34 of the pusher 14 interferes with the ramp 42 and it is directed by it towards the lobe 47 of the cavity 36 located in the extension of exit S.

    Ainsi, lorsque cette nouvelle action d'enfoncement sur le bouton de commande 15 est relâchée, l'ergot d'accrochage 34 peut regagner par la sortie S la cavité 44, suivant la flèche F3 de la figure 4A, ce qui permet le retour du poussoir 14 dans sa position déployée initiale.So when this new push down action the control button 15 is released, the latching lug 34 can return via the exit S cavity 44, according to the arrow F3 of Figure 4A, which allows the return of the pusher 14 in its initial deployed position.

    Dans la forme de réalisation représentée, les moyens de liberté 24 que comporte le sélecteur 22 conjointement avec les moyens d'accrochage 23 précédents forment en creux sur ce sélecteur 22, pour l'ergot d'accrochage 34 du poussoir 14, une simple piste en cul-de-sac, qui, pour la position de non-ingérence du sélecteur 22, vient s'abouter à la cavité 44 du boítier 11, à la manière de la cavité 36 précédente, et au lieu et place de celle-ci.In the embodiment shown, the means freedom 24 that includes the selector 22 together with the previous hooking means 23 form hollow on this selector 22, for the latching lug 34 of the pusher 14, a single dead end track, which for the position of non-interference of the selector 22, comes into contact with the cavity 44 of the housing 11, like the previous cavity 36, and place and place thereof.

    Ainsi, lorsque, pour cette position de non-ingérence du sélecteur 22, une action d'enfoncement est exercée sur le bouton de commande 15 suivant la flèche F4 de la figure 4B, l'ergot d'accrochage 34 suit librement la piste en cul-de-sac que forment les moyens de liberté 24 de ce sélecteur 22, sans un quelconque accrochage, en sorte que, lorsque cette action d'enfoncement est relâchée, le poussoir 14 revient librement à sa position déployée initiale, sans être retenu en position rétractée.So when, for this position of non-interference of the selector 22, a pressing action is exerted on the control button 15 along arrow F4 in FIG. 4B, the hooking lug 34 freely follows the dead end track that form the freedom means 24 of this selector 22, without any hooking, so that when this action is released, the pusher 14 returns freely in its initial deployed position, without being held in position retracted.

    Dans la forme de réalisation représentée, les moyens de liberté 24 sont distants angulairement de 90° des moyens d'accrochage 23.In the embodiment shown, the means of freedom 24 are angularly distant by 90 ° from the means hanging 23.

    Autrement dit, il faut faire pivoter de 90° le sélecteur 22 pour le faire passer de sa position d'ingérence à sa position de non-ingérence, et réciproquement.In other words, you have to rotate 90 ° the selector 22 to move it from its interference position to its position of non-interference, and vice versa.

    En pratique, pour une définition positive de l'une et l'autre de ses positions, le sélecteur 22 comporte, en saillie, dans la forme de réalisation représentée, un doigt 50, par lequel, en position de non-ingérence ou en position d'ingérence, il coopère en butée avec l'un ou l'autre de deux épaulements d'arrêt 51 prévus à cet effet sur le boítier 11. In practice, for a positive definition of one and the other of its positions, the selector 22 comprises, projecting, in the embodiment shown, a finger 50, by which, in a position of non-interference or in a position interference, it cooperates in abutment with one or the other of two stop shoulders 51 provided for this purpose on the housing 11.

    De préférence, et tel que représenté, il est prévu, entre le sélecteur 22 et le boítier 11, pour le maintien stable du sélecteur 22 dans l'une et l'autre de ses positions, des moyens d'indexation.Preferably, and as shown, provision is made, between the selector 22 and the housing 11, for stable maintenance selector 22 in either of its positions, means of indexing.

    Dans la forme de réalisation représentée, ces moyens d'indexation comportent, d'une part, sur le sélecteur 22, sur la face de celui-ci opposée à celle sur laquelle sont formés les moyens d'accrochage 23 et de liberté 24, un bossage 52, en forme de dièdre, et, d'autre part, sur le boítier 11, deux logements 54, eux aussi en forme de dièdre, qui correspondent chacun respectivement aux deux positions du sélecteur 22, et avec chacun desquels le bossage 52 est apte à coopérer en emboítement.In the embodiment shown, these means on the one hand, on the selector 22, on the face of it opposite to that on which are formed the attachment means 23 and freedom 24, a boss 52, in dihedral shape, and, on the other hand, on the housing 11, two housings 54, also in the form of a dihedral, which correspond each respectively at the two positions of the selector 22, and with each of which the boss 52 is able to cooperate in interlocking.

    En pratique, le bossage 52 du sélecteur 22 est porté par une patte 55 individualisée radialement dans celui-ci par deux fentes 56, pour bénéficier d'un certain jeu élastique de la part de cette patte 55.In practice, the boss 52 of the selector 22 is worn by a lug 55 individualized radially therein by two slots 56, to benefit from a certain elastic play of the share of this leg 55.

    Préférentiellement, enfin, et tel que représenté, il est prévu, entre le sélecteur 22 et le poussoir 14, des moyens d'emboítement, pour le blocage en rotation du sélecteur 22 par le poussoir 14 dès que ce poussoir 14 est écarté de sa position déployée.Preferably, finally, and as shown, it is provided between the selector 22 and the pusher 14, means socket, for locking the selector 22 in rotation by the pusher 14 as soon as this pusher 14 is removed from its position deployed.

    Dans la forme de réalisation représentée, ces moyens d'emboítement comportent, d'une part, sur le poussoir 14, une nervure 57, qui fait saillie sur la face de ce poussoir 14 tournée vers le sélecteur 22, parallèlement à la direction de trajet T, et dont l'extrémité d'attaque est biseautée par un chanfrein 58, et, d'autre part, sur le sélecteur 22, deux rainures 59, qui correspondent chacune respectivement à l'une et l'autre des positions de ce sélecteur 22, et qui sont donc à 90° l'une par rapport à l'autre dans la forme de réalisation représentée.In the embodiment shown, these means socket comprise, on the one hand, on the pusher 14, a rib 57, which protrudes from the face of this pusher 14 facing the selector 22, parallel to the direction of path T, and the leading end of which is bevelled by a chamfer 58, and, on the other hand, on the selector 22, two grooves 59, which each correspond respectively to one and the other of the positions of this selector 22, and which are therefore 90 ° to each other in the embodiment represented.

    Dès que le poussoir 14 est écarté de sa position déployée, sa nervure 57 s'engage dans l'une ou l'autre des rainures 59 du sélecteur 22, suivant la position de celui-ci.As soon as the pusher 14 is removed from its position deployed, its rib 57 engages in one or other of the grooves 59 of the selector 22, according to the position thereof.

    Le changement de position du sélecteur 22 ne peut donc intervenir que lorsque le poussoir 14 est en position déployée. The change of position of the selector 22 cannot therefore intervene only when the pusher 14 is in the deployed position.

    Autrement dit, le changement de position du sélecteur 22 ne peut intervenir que lorsque, l'ergot d'accrochage 34 du poussoir 14 étant à l'abri dans la cavité 44 du boítier 11, à l'écart du trajet du sélecteur 22, ce sélecteur 22 n'est pas susceptible d'interférer avec lui lors de son passage d'une de ses positions à l'autre.In other words, changing the position of the selector 22 can only intervene when the hooking lug 34 of the pusher 14 being sheltered in the cavity 44 of the housing 11, at the deviation of the path of the selector 22, this selector 22 is not likely to interfere with him when passing from one of his positions to the next.

    Il est ainsi évité que, pour toute position du poussoir 14 autre que sa position déployée, une éventuelle malencontreuse action sur le sélecteur 22 soit de nature à conduire à un coincement, voire même à un endommagement, de l'ergot d'accrochage 34, et, par suite, à une détérioration de l'ensemble.It is thus avoided that, for any position of the pusher 14 other than its deployed position, a possible unfortunate action on the selector 22 is such as to lead to jamming or even damage to the lug 34, and, as a result, a deterioration of all.

    En particulier, au lieu d'être monté rotatif, le sélecteur pourrait tout aussi bien être monté mobile en translation.In particular, instead of being rotatably mounted, the selector could just as easily be mounted mobile translation.

    En outre, il peut être prévu côte à côte deux ou plusieurs poussoirs, à raison, par exemple, d'un par contact mobile à commander.In addition, it can be provided side by side two or several pushers, for example, one per contact mobile to order.
