The appts. is for a pushbutton (12) movable in the axial direction which consists of a sleeve (12A) and a threaded rod (12B) which is urged out of it by the spring (44) bearing upon the hood of the mechanism (11). The cap (15) of the pushbutton is mounted movably on a plate (14) at least partially surrounding the support (13) to which the mechanism is fixed. The sleeve is immobilised against rotation and has an internal bore into which the rod is screwed. The threads are of large pitch equal to about 2.5 times the diameter of the rod, and have an isosceles trapezoidal profile with edges at an angle of about 100 degrees to each other.

Description

La présente invention concerne d'une manière générale les appareils ou appareillages électriques du genre comportant un mécanisme auquel il est associé pour sa commande un poussoir monté mobile axialement, un support, dont le mécanisme est solidaire, et qui, en pratique, est destiné à porter contre une quelconque surface d'appui par une portion au moins de sa périphérie, une plaque, qui, rapportée sur le support et entourant au moins partiellement celui-ci, est, elle, susceptible, en pratique, de porter sur la même surface d'appui que ce support ou sur une surface d'appui sensiblement parallèle à celle-ci, et une touche de manoeuvre, qui, à la disposition de l'usager, est montée mobile sur la plaque, en étant par exemple pivotante sur celle-ci, et est ainsi apte agir, soit directement, soit indirectement, sur le poussoir de commande du mécanisme.The present invention relates generally to electrical apparatus or apparatus of the kind comprising a mechanism with which it is associated for its control a pusher mounted axially movable, a support, whose mechanism is integral, and which, in practice, is intended to bear against any bearing surface by at least a portion of its periphery, a plate, which, attached to the support and surrounding it at least partially, is, in turn, capable of bearing on the same surface support that this support or on a support surface substantially parallel thereto, and an operating button, which, at the disposal of the user, is movably mounted on the plate, being for example pivotable on that -this, and is thus able to act, either directly or indirectly, on the control button of the mechanism.

Elle vise plus particulièrement, mais non nécessairement exclusivement, le cas des appareils électriques à encastrer dans un mur.It relates more particularly, but not necessarily exclusively, to the case of electrical appliances to be built into a wall.

La surface d'appui contre laquelle est amené à porter leur support est usuellement directement formée par le mur nu.The bearing surface against which is brought to bear their support is usually directly formed by the bare wall.

Il n'en est pas de même pour la plaque, qui, appartenant à l'habillage de l'ensemble, doit au contraire, après finition, venir recouvrir le revêtement alors usuellement appliqué à ce mur.It is not the same for the plate, which, belonging to the covering of the assembly, must on the contrary, after finishing, come to cover the coating then usually applied to this wall.

Suivant l'épaisseur de ce revêtement, notamment lorsqu'il s'agit de tissu, il existe inévitablement un écart entre les surfaces d'appui, ou plans de repos, contre lesquels portent in fine le support et la plaque.Depending on the thickness of this coating, especially in the case of fabric, there is inevitably a gap between the bearing surfaces, or rest planes, against which ultimately bear the support and the plate.

Le poussoir étant porté par le support par l'intermédiaire du mécanisme tandis que la touche de manoeuvre est portée par la plaque, cet écart peut être préjudiciable au bon fonctionnement de l'ensemble.The pusher being carried by the support through the mechanism while the operating button is carried by the plate, this difference can be detrimental to the proper functioning of the assembly.

C'est le cas, notamment, lorsque le mécanisme est particulièrement sensible à la course axiale du poussoir qui le commande, comme cela est le cas par exemple pour les interrupteurs électroniques pilotés par un microrupteur.This is the case, in particular, when the mechanism is particularly sensitive to the axial stroke of the pusher which controls it, as is the case for example for electronic switches controlled by a microswitch.

Il est dès lors nécessaire à l'installateur de procéder à un réglage après pose, pour compenser cet écart entre les surfaces d'appui du support et de la plaque, ou, plus précisément, pour compenser le jeu axial qui en résulte entre le poussoir et la touche de manoeuvre.It is therefore necessary for the installer to make an adjustment after installation, to compensate for this difference between the bearing surfaces of the support and of the plate, or, more precisely, to compensate for the axial play which results therefrom between the pusher. and the operating button.

Il est prévu, à ce jour, pour ce réglage, d'équiper le poussoir d'une vis de réglage, ou, autrement dit, de former ce poussoir de deux pièces en relation de vissage l'une par rapport à l'autre, à savoir, d'une part, un manchon, qui, formant le poussoir proprement dit, est bloqué en rotation tout en étant mobile axialement, et dont l'alésage interne est taraudé, et, d'autre part, une tige filetée, qui, formant la vis de réglage proprement dite, est en prise à vissage avec le manchon précédent.It is planned, to date, for this adjustment, to equip the pusher with an adjustment screw, or, in other words, to form this pusher with two parts in screwing relation to each other, namely, on the one hand, a sleeve, which, forming the pusher itself, is locked in rotation while being axially movable, and whose internal bore is tapped, and, on the other hand, a threaded rod, which , forming the adjustment screw proper, is in screw connection with the preceding sleeve.

En pratique, la vis de réglage que constitue cette tige filetée est une vis classique, c'est-à-dire une vis dont le pas est relativement réduit, et, en tout cas, suffisamment faible pour que toute action simplement axiale à laquelle elle pourrait être soumise ne soit pas de nature à en induire une quelconque rotation.In practice, the adjustment screw that constitutes this threaded rod is a conventional screw, that is to say a screw whose pitch is relatively reduced, and, in any case, sufficiently weak for any simply axial action to which it could be subject is not likely to induce any rotation.

Pour un vissage ou un dévissage, il faut donc intervenir sur cette vis de réglage à l'aide d'un outil, et sa tête comporte une empreinte appropriée à cet effet.For a screwing or unscrewing, it is therefore necessary to intervene on this adjusting screw using a tool, and its head has an imprint suitable for this purpose.

Cette disposition a donné et peut encore donner satisfaction.This arrangement has given and can still give satisfaction.

Mais, outre la nécessite à laquelle elle conduit de disposer d'un outil, elle présente des inconvénients, qui sont les suivants.But, in addition to the need to which it leads to having a tool, it has drawbacks, which are as follows.

Tout d'abord, pour avoir accès à la vis de réglage, il faut inévitablement procéder à un démontage au moins partiel de l'appareil.First of all, to have access to the adjustment screw, you must inevitably carry out an at least partial disassembly of the device.

En outre, le réglage à effectuer ne peut qu'être exécuté en aveugle, sa vérification nécessitant de procéder ensuite au remontage de cet appareil.In addition, the adjustment to be made can only be carried out blind, its verification necessitating then reassembling this device.

Enfin, tout choc excessif sur la touche de manoeuvre, dûment transmis à la vis de réglage, est susceptible d'être destructeur à l'égard du taraudage avec lequel elle est en prise, au détriment du fonctionnement ultérieur de l'appareil.Finally, any excessive impact on the operating button, duly transmitted to the adjusting screw, is likely to be destructive with regard to the internal thread with which it is in operation. taken, to the detriment of the subsequent operation of the device.

La présente invention a d'une manière générale pour objet une disposition qui, de manière relativement simple, permet avantageusement d'éviter ces inconvénients.The present invention generally relates to an arrangement which, relatively simply, advantageously makes it possible to avoid these drawbacks.

De manière plus précise, elle a pour objet un appareil électrique du genre comportant un mécanisme auquel il est associé pour sa commande un poussoir monté mobile axialement, un support, dont le mécanisme est solidaire, une plaque qui, rapportée sur le support, entoure au moins partiellement celui-ci, et une touche de manoeuvre, qui, à la disposition de l'usager, est montée mobile sur la plaque et est apte à agir, soit directement, soit indirectement, sur le poussoir, ce poussoir comportant deux pièces en relation de vissage l'une par rapport à l'autre, à savoir, d'une part, un manchon, qui est bloqué en rotation tout en étant mobile axialement, et dont l'alésage interne est taraudé, et, d'autre part, une tige filetée, qui est en prise à vissage avec ce manchon, cet appareil électrique étant d'une manière générale caractérisé en ce que le ou les filets que présente la tige filetée du poussoir sont des filets à grand pas et en ce que cette tige filetée est soumise à des moyens élastiques de rappel qui tendent en permanence à l'extraire du manchon avec lequel elle est en prise.More specifically, it relates to an electrical appliance of the kind comprising a mechanism with which it is associated for its control a pusher mounted axially movable, a support, whose mechanism is integral, a plate which, attached to the support, surrounds the at least partially this, and an operating button, which, at the disposal of the user, is movably mounted on the plate and is capable of acting, either directly or indirectly, on the pusher, this pusher comprising two pieces in screwing relation to each other, namely, on the one hand, a sleeve, which is locked in rotation while being axially movable, and whose internal bore is tapped, and, on the other hand , a threaded rod, which is in screw connection with this sleeve, this electrical appliance being generally characterized in that the thread or threads presented by the threaded rod of the pusher are threads with large pitch and in that this threaded rod is subjected to elastic return means which constantly tend to extract it from the sleeve with which it is engaged.

Grâce à une telle disposition, la tige filetée du poussoir est en permanence l'objet d'un couple de dévissage assurant systématiquement le rattrapage de tout jeu axial éventuel entre le poussoir et la touche de manoeuvre, cependant que, comme il est de règle, tout effort d'enfoncement exercé sur cette touche de manoeuvre se trouve dûment transmis axialement par le poussoir au mécanisme sous-jacent, pour la commande de celui-ci.Thanks to such an arrangement, the threaded rod of the pusher is permanently the object of a unscrewing torque systematically ensuring the take-up of any axial play between the pusher and the operating key, however, as is the rule, any driving force exerted on this operating key is duly transmitted axially by the pusher to the underlying mechanism, for the control thereof.

Lors de l'installation de l'appareil électrique suivant l'invention, ou ultérieurement, il n'est donc besoin d'aucun réglage de cet appareil électrique, ce réglage se faisant automatiquement de lui-même, par le rattrapage de jeu axial systématique précédent.During the installation of the electrical device according to the invention, or subsequently, there is therefore no need for any adjustment of this electrical device, this adjustment being done automatically by itself, by taking up systematic axial play previous.

Il en résulte avantageusement l'élimination de la nécessité de procéder à un quelconque démontage, même partiel, de cet appareil électrique pour ce réglage, aussi bien que l'élimination de la nécessité de disposer pour ce faire d'un quelconque outil.This advantageously results in the elimination of the need to carry out any disassembly, even partial, of this electrical device for this adjustment, as well as the elimination of the need to have any tool to do this.

Enfin, tout choc éventuel sur la touche de manoeuvre est avantageusement susceptible d'être supporté au mieux par le poussoir, sans destruction du taraudage de son manchon, ce choc pouvant tout au plus conduire à un enfoncement momentané dans ce manchon de la tige filetée qui est en prise avec lui.Finally, any possible impact on the operating button is advantageously likely to be best supported by the pusher, without destroying the tapping of its sleeve, this impact possibly at most leading to a momentary depression in this sleeve of the threaded rod which is engaged with him.

Tel qu'illustré sur ces figures, l'appareil électrique 10 suivant l'invention comporte, globalement, de manière connue en soi, un mécanisme 11, auquel il est associé, pour sa commande, un poussoir 12 monté mobile axialement, un support 13, dont est solidaire le mécanisme 11, une plaque 14, qui, rapportée sur le support 13, entoure au moins partiellement celui-ci, et une touche de manoeuvre 15, qui, à la disposition de l'usager, est montée mobile sur la plaque 14 et est apte à agir, soit directement, soit indirectement, sur le poussoir 12.As illustrated in these figures, the electrical apparatus 10 according to the invention comprises, overall, in a manner known per se, a mechanism 11, with which it is associated, for its control, a pusher 12 mounted axially movable, a support 13 , which is integral with the mechanism 11, a plate 14, which, attached to the support 13, at least partially surrounds the latter, and an operating button 15, which, at the disposal of the user, is movably mounted on the plate 14 and is able to act, either directly or indirectly, on the pusher 12.

Sur ces figures, et à titre d'exemple, l'appareil électrique 10 est un interrupteur électronique, dont le mécanisme 11 est piloté par un microrupteur 16.In these figures, and by way of example, the electrical device 10 is an electronic switch, the mechanism 11 of which is controlled by a microswitch 16.

En outre, dans la forme de réalisation représentée, le mécanisme 11 comporte un levier 21, qui, par des oreilles 22 implantées le long d'un de ses bords, est monté pivotant sur des tourillons 23 prévus à cet effet sur le capot 19, et contre la partie centrale duquel porte, suivant des dispositions décrites plus en détail ultérieurement, le poussoir 12.In addition, in the embodiment shown, the mechanism 11 comprises a lever 21, which, by lugs 22 implanted along one of its edges, is pivotally mounted on pins 23 provided for this purpose on the cover 19, and against the central part of which carries, according to arrangements described in more detail later, the pusher 12.

C'est donc par ce levier 21, monté pivotant sur le mécanisme 11, que, dans la forme de réalisation représentée, la touche de manoeuvre 15 est apte à agir sur le poussoir 12, cette touche de manoeuvre 15 portant sur ce levier 21 le long du bord de celui-ci opposé à ses oreilles 22.It is therefore by this lever 21, pivotally mounted on the mechanism 11, that, in the embodiment shown, the operating button 15 is able to act on the pusher 12, this operating button 15 bearing on this lever 21 the along the edge thereof opposite his ears 22.

Pour une limitation de son débattement, le levier 21 présente, latéralement, des pattes 24, qui s'engagent dans le capot 19 à la faveur d'évidements 25 prévus à cet effet sur celui-ci, et par lesquelles il est apte à se crocheter sur ce capot 19.For a limitation of its movement, the lever 21 has, laterally, tabs 24, which engage in the cover 19 by means of recesses 25 provided for this purpose thereon, and by which it is able to crochet on this cover 19.

Sur les figures, l'appareil électrique 10 suivant l'invention est par ailleurs destiné à être encastré dans un mur 27, ou, plus exactement, dans une boîte d'encastrement, non représentée, logée à cet effet dans un évidement 28 de ce mur 27.In the figures, the electrical device 10 according to the invention is also intended to be built into a wall 27, or, more precisely, into a built-in box, not shown, housed for this purpose in a recess 28 of this wall 27.

Le support 13 que comporte cet appareil électrique 10 est donc adapté à être rapporté sur la boîte d'encastrement ainsi mise en oeuvre, par exemple par des vis non représentées. Il comporte à cet effet des perçages 29.The support 13 that this electrical device 10 comprises is therefore adapted to be attached to the mounting box thus implemented, for example by screws not shown. To this end, it has holes 29.

Le support 13 ne relevant pas par lui-même de la présente invention, il ne sera pas non plus décrit dans tous ses détails ici.The support 13 does not by itself fall within the scope of the present invention, nor will it be described in all its details here.

Il suffira d'indiquer que, dans la forme de réalisation représentée, il est destiné à porter par une portion au moins de sa périphérie contre la surface d'appui 30 que forme autour de son évidement 28 le mur 27, que, dans sa partie centrale, il comporte un évidement central 31 pour l'engagement du mécanisme 11, et que celui-ci lui est rapporté par encliquetage.It will suffice to indicate that, in the embodiment shown, it is intended to bear by at least a portion of its periphery against the bearing surface 30 formed around its recess 28 by the wall 27, that, in its part central, it has a central recess 31 for engaging the mechanism 11, and that the latter is attached to it by snap-fastening.

En pratique, le capot 19 du mécanisme 11 présente, en positions opposées l'une par rapport à l'autre, deux crochets 32 par lesquels il est apte à venir en prise avec des crans 33 prévus en correspondance à cet effet en bordure de l'évidement central 31 du support 13.In practice, the cover 19 of the mechanism 11 has, in positions opposite one with respect to the other, two hooks 32 by which it is capable of engaging with notches 33 provided in correspondence for this purpose at the edge of the 'central recess 31 of the support 13.

Dans la forme de réalisation représentée, la plaque 14 entoure entièrement le support 13, et, s'étendant ainsi au-delà de ce support 13 à sa périphérie, elle est susceptible de venir porter soit sur la même surface d'appui 30 que lui, comme représenté sur la figure 1, soit, comme représenté sur la figure 10, sur une surface d'appui 30', qui, sensiblement parallèle à la surface d'appui 30, est formée par un revêtement 35 rapporté sur le mur 27 autour du support 13.In the embodiment shown, the plate 14 completely surrounds the support 13, and, thus extending beyond this support 13 at its periphery, it is capable of coming to bear either on the same bearing surface 30 as it , as shown in Figure 1, or, as shown in Figure 10, on a bearing surface 30 ', which, substantially parallel to the bearing surface 30, is formed by a coating 35 attached to the wall 27 around of the support 13.

En pratique, dans la forme de réalisation représentée, la plaque 14 est apte à être rapportée par des vis, non représentées, sur le support 13.In practice, in the embodiment shown, the plate 14 is able to be attached by screws, not shown, to the support 13.

Elle comporte à cet effet des oreilles 36 et, en correspondance, le support 13 comporte des puits 37.To this end, it includes ears 36 and, in correspondence, the support 13 includes wells 37.

Dans la forme de réalisation représentée, la touche de manoeuvre 15 se loge dans un évidement central 38 de la plaque 14 en bordure duquel interviennent les oreilles 36 de celle-ci, et elle est montée pivotante sur cette plaque 14.In the embodiment shown, the operating button 15 is housed in a central recess 38 of the plate 14 at the edge of which the ears 36 of the latter intervene, and it is pivotally mounted on this plate 14.

En pratique, la touche de manoeuvre 15 comporte, latéralement, pour ce faire, des oreilles 40 par lesquelles elle est encliquetée sur des tourillons 41 prévus en correspondance à cet effet sur la plaque 14, en bordure de son évidement central 38, entre ses oreilles 36.In practice, the operating button 15 comprises, laterally, to do this, ears 40 by which it is snapped onto pins 41 provided in correspondence for this purpose on the plate 14, at the edge of its central recess 38, between its ears 36.

Les dispositions qui précèdent sont bien connues par elles-mêmes, au moins dans leur principe, et elles ne seront donc pas décrites plus en détail ici.The foregoing arrangements are well known in themselves, at least in principle, and will therefore not be described in more detail here.

De manière également connue dans son principe, le poussoir 12 comporte deux pièces en relation de vissage l'une par rapport à l'autre, à savoir, d'une part, un manchon 12A, qui est bloqué en rotation tout en étant mobile axialement, et dont l'alésage interne 42 est taraudé, et, d'autre part, une tige filetée 12B, qui est en prise à vissage avec le manchon 12A.In a manner also known in principle, the pusher 12 comprises two parts in screwing relation to one another, namely, on the one hand, a sleeve 12A, which is locked in rotation while being axially movable , and whose internal bore 42 is tapped, and, on the other hand, a threaded rod 12B, which is in screw connection with the sleeve 12A.

Suivant l'invention, le ou les filets 43 que présente la tige filetée 12B du poussoir 12 sont des filets à grand pas P, suivant des dispositions décrites plus en détail ultérieurement, et, conjointement, la tige filetée 12B est soumise à des moyens élastiques de rappel 44 tendant en permanence à l'extraire du manchon 12A avec lequel elle est en prise.According to the invention, the thread or threads 43 presented by the threaded rod 12B of the pusher 12 are threads with large pitch P, according to arrangements described in more detail later, and, jointly, the threaded rod 12B is subjected to elastic means return 44 tending permanently to extract it from the sleeve 12A with which it is engaged.

Dans la forme de réalisation représentée, le manchon 12A est destiné à la commande du mécanisme 11, par action sur le microrupteur 16 pilotant celui-ci, et, plus précisément, sur l'ergot 17 de ce microrupteur 16, tandis que la tige filetée 12B est destinée à l'action de la touche de manoeuvre 15.In the embodiment shown, the sleeve 12A is intended for controlling the mechanism 11, by action on the microswitch 16 controlling the latter, and, more precisely, on the lug 17 of this microswitch 16, while the threaded rod 12B is intended for the action of the operating button 15.

Le manchon 12A s'étend donc du côté du mécanisme 11, et la tige filetée 12B du côté de la touche de manoeuvre 15.The sleeve 12A therefore extends on the side of the mechanism 11, and the threaded rod 12B on the side of the operating button 15.

Dans la forme de réalisation représentée, le manchon 12A présente un fond borgne 46, et c'est par celui-ci qu'il est apte à agir sur l'ergot 17 du microrupteur 16.In the embodiment shown, the sleeve 12A has a blind bottom 46, and it is through this that it is able to act on the lug 17 of the microswitch 16.

Dans la forme de réalisation représentée, le manchon 12A, qui est globalement cylindrique, a, extérieurement, une section transversale circulaire.In the embodiment shown, the sleeve 12A, which is generally cylindrical, has, on the outside, a circular cross section.

Il présente, en saillie, du côté du microrupteur 16, mais légèrement en retrait par rapport à son fond borgne 46, une collerette d'arrêt 48, pour coopération en butée avec la tranche 49 correspondante de la douille 20 dans laquelle il est engagé.It has, projecting from the side of the microswitch 16, but slightly set back relative to its blind bottom 46, a stop collar 48, for cooperation in abutment with the corresponding edge 49 of the socket 20 in which it is engaged.

Cette collerette d'arrêt 48, qui, pour des raisons d'encombrement a, extérieurement, dans la forme de réalisation représentée, un contour particulier, présente localement une encoche 52, pour engagement à coulissement sur un prolongement local 53 de la douille 20 destiné à assurer le blocage en rotation du manchon 12A sur le mécanisme 11, et, donc, son blocage en rotation par rapport à la tige filetée 12B.This stop collar 48, which, for reasons of space, externally, in the embodiment shown, a particular contour, locally has a notch 52, for sliding engagement on a local extension 53 of the socket 20 intended to ensure the locking in rotation of the sleeve 12A on the mechanism 11, and therefore its locking in rotation relative to the threaded rod 12B.

Du côté opposé au microrupteur 16, l'arête extérieure du manchon 12A est abattue par un chanfrein 54, pour faciliter son engagement dans la douille 20.On the side opposite to the microswitch 16, the outer edge of the sleeve 12A is cut down by a chamfer 54, to facilitate its engagement in the socket 20.

Intérieurement, le manchon 12A présente, dans son alésage interne 42, un nombre de sillons hélicoïdaux 55 égal à celui des filets 43 de la tige filetée 12B.Internally, the sleeve 12A has, in its internal bore 42, a number of helical grooves 55 equal to that of the threads 43 of the threaded rod 12B.

Dans la forme de réalisation représentée, la tige filetée 12B comporte en effet plusieurs filets 43, en l'espèce quatre, et, donc, le manchon 12A comporte intérieurement quatre sillons hélicoïdaux 55, qui, bien entendu, tous identiques entre eux, sont complémentaires, chacun respectivement, des filets 43 de la tige filetée 12B.In the embodiment shown, the threaded rod 12B indeed comprises several threads 43, in this case four, and, therefore, the sleeve 12A internally comprises four helical grooves 55, which, of course, all identical to each other, are complementary , each respectively, of the threads 43 of the threaded rod 12B.

Pour une bonne réversibilité du vissage, et tel que repéré sur la figure 5, le pas P des filets 43 de la tige filetée 12B est préférentiellement supérieur à 1,5 fois le diamètre D de cette tige filetée 12B, mesuré extérieurement, sur la crête de ces filets 43.For good reversibility of the screwing, and as indicated in FIG. 5, the pitch P of the threads 43 of the threaded rod 12B is preferably greater than 1.5 times the diameter D of this threaded rod 12B, measured externally, on the crest of these nets 43.

Le pas P étant en pratique supérieur à la hauteur H de la tige filetée 12B dans la forme de réalisation représentée, l'un des filets 43 a été prolongé en traits interrompus sur la figure 5 pour qu'il puisse y être dûment repéré.The pitch P being in practice greater than the height H of the threaded rod 12B in the embodiment shown, one of the threads 43 has been extended in broken lines in FIG. 5 so that it can be duly identified there.

En pratique, dans la forme de réalisation représentée, le pas P des filets 43 de la tige filetée 12B est sensiblement égal à 2,5 fois le diamètre D de celle-ci mesuré dans les conditions précédemment précisées.In practice, in the embodiment shown, the pitch P of the threads 43 of the threaded rod 12B is substantially equal to 2.5 times the diameter D of the latter measured under the conditions previously specified.

Par ailleurs, dans cette forme de réalisation, et ainsi qu'il ressort de la figure 6 pour l'un d'eux, les filets 43 de la tige filetée 12B ont un profil trapézoïdal, et, plus précisément, un profil trapézoïdal isocèle dont les côtés ou flancs 56 font entre eux un angle A supérieur à 90°. Par exemple, cet angle A est voisin de 100°.Furthermore, in this embodiment, and as can be seen from FIG. 6 for one of them, the threads 43 of the threaded rod 12B have a trapezoidal profile, and, more precisely, an isosceles trapezoidal profile of which the sides or sides 56 form an angle A greater than 90 ° between them. For example, this angle A is close to 100 °.

Mais, en pratique, tout autre profil pourrait convenir, tout en étant cependant préférentiellement symétrique.However, in practice, any other profile could be suitable, while however preferably being symmetrical.

Enfin, dans la forme de réalisation représentée, la tige filetée 12B présente une tête 57 sur laquelle portent les moyens élastiques de rappel 44 qui lui sont associés.Finally, in the embodiment shown, the threaded rod 12B has a head 57 on which bear the elastic return means 44 which are associated with it.

En pratique, ces moyens élastiques de rappel 44 sont constitués par un ressort, du type ressort à boudin, qui est globalement tronconique, et qui prend appui sur le capot 19 du mécanisme 11, autour d'un bourrelet de centrage 58 qui, en saillie sur ce capot 19, forme en pratique un prolongement de la douille 20 que comporte celui-ci.In practice, these elastic return means 44 are constituted by a spring, of the coil spring type, which is generally frustoconical, and which bears on the cover 19 of the mechanism 11, around a centering bead 58 which, projecting on this cover 19, in practice forms an extension of the socket 20 which the latter comprises.

A la différence de la tête d'une vis de type classique, la tête 57 de la tige filetée 12B est lisse.Unlike the head of a conventional type screw, the head 57 of the threaded rod 12B is smooth.

Pour son contact avec le levier 21 contre lequel elle porte sous la sollicitation des moyens élastiques de rappel 44, elle est globalement bombée.For its contact with the lever 21 against which it bears under the stress of the elastic return means 44, it is generally convex.

Alors que le manchon 12A est préférentiellement en matière synthétique, la tige filetée 12B est préférentiellement en métal.While the sleeve 12A is preferably made of synthetic material, the threaded rod 12B is preferably made of metal.

Quoi qu'il en soit, sous la sollicitation des moyens élastiques de rappel 44, la tige filetée 12B est en permanence l'objet d'un couple de desserrage, qui tend à l'extraire du manchon 12A, en direction de la touche de manoeuvre 15.Anyway, under the request of the elastic return means 44, the threaded rod 12B is permanently the object of a loosening torque, which tends to extract it from the sleeve 12A, in the direction of the operating button 15.

Tel que schématisé par la flèche F1 sur les figures 1 et 2, l'effort axial d'extraction correspondant a plusieurs effets.As shown schematically by the arrow F1 in Figures 1 and 2, the axial extraction force corresponding to several effects.

Tout d'abord, il maintient la tige filetée 12B appliquée par sa tête 57 sur le levier 21.First of all, it maintains the threaded rod 12B applied by its head 57 to the lever 21.

Mais, par l'intermédiaire de cette tige filetée 12B, il maintient également ce levier 21 en application contre la touche de manoeuvre 15, du côté de ce levier 21 opposé aux oreilles 22 par lesquelles il est articulé au capot 19 du mécanisme 11.However, by means of this threaded rod 12B, it also maintains this lever 21 in application against the operating button 15, on the side of this lever 21 opposite the ears 22 by which it is articulated to the cover 19 of the mechanism 11.

Enfin, la tige filetée 12B entraînant le manchon 12A avec lequel elle est en prise, l'effort axial d'extraction dont est l'objet cette tige filetée 12B maintient normalement ce manchon 12A en butée par sa collerette d'arrêt 48 contre la tranche 49 de la douille 20 dans laquelle il est engagé.Finally, the threaded rod 12B driving the sleeve 12A with which it is engaged, the axial extraction force which is the object of this threaded rod 12B normally maintains this sleeve 12A in abutment by its stop collar 48 against the edge 49 of the socket 20 in which it is engaged.

Pour cette position de butée, qui correspond à la configuration de repos de l'ensemble, le manchon 12A du poussoir 12 suivant l'invention est à distance, mais à très faible distance, de l'ergot 17 du microrupteur 16, qui, dès lors, est dans un premier état.For this stop position, which corresponds to the rest configuration of the assembly, the sleeve 12A of the pusher 12 according to the invention is at a distance, but at a very short distance, from the lug 17 of the microswitch 16, which, from therefore, is in a first state.

Si, pour la configuration d'actionnement de l'ensemble, la touche de manoeuvre 15 est l'objet d'une action de basculement, il en est de même pour le levier 21 du mécanisme 11, et, tel que schématisé par la flèche F2, opposée à la précédente, sur la figure 9, la tige filetée 12B du poussoir 12 suivant l'invention est alors l'objet, à l'encontre de ses moyens élastiques de rappel 44, d'une action d'enfoncement au cours de laquelle elle entraîne axialement celui-ci et provoque donc son action sur l'ergot 17 du microrupteur 16, qui, dès lors, bascule dans son deuxième état, distinct du précédent.If, for the actuation configuration of the assembly, the operating button 15 is the subject of a tilting action, the same applies to the lever 21 of the mechanism 11, and, as shown schematically by the arrow F2, opposite to the previous one, in FIG. 9, the threaded rod 12B of the pusher 12 according to the invention is then the object, against its elastic return means 44, of a driving action during from which it axially drives the latter and therefore causes its action on the lug 17 of the microswitch 16, which, therefore, switches to its second state, distinct from the previous one.

Dans un premier temps, l'effort développé n'est pas suffisant pour qu'il en résulte un quelconque début de vissage de la tige filetée 12B dans le manchon 12A, et il en est en pratique ainsi jusqu'à ce que l'ergot 17 du microrupteur 16 arrive en fin de course.At first, the effort developed is not sufficient for it to result in any beginning of screwing of the threaded rod 12B in the sleeve 12A, and this is in practice so until the lug 17 of the microswitch 16 arrives at the end of the race.

Au-delà, et, donc, dans un deuxième temps, si l'action exercée sur la touche de manoeuvre 15 est poursuivie, l'effort développé devient supérieur à l'effort antagoniste exercé par les moyens élastiques de rappel 44, et la tige filetée 12B pénètre axialement dans le manchon 12A en se vissant dans celui-ci.Beyond, and therefore, in a second step, if the action exerted on the operating button 15 is continued, the force developed becomes greater than the opposing force exerted by the elastic return means 44, and the rod 12B thread enters axially into the sleeve 12A by screwing into it.

Lorsque l'action exercée sur la touche de manoeuvre 15 est relâchée, les moyens élastiques de rappel 44 ramènent dans leur configuration initiale de repos la tige filetée 12B, le manchon 12A, le levier 21 du mécanisme 11 et la touche de manoeuvre 15, cependant que le microrupteur 16 revient lui-même à son premier état.When the action exerted on the operating button 15 is released, the elastic return means 44 return the threaded rod 12B, the sleeve 12A, the lever 21 of the mechanism 11 and the operating button 15 to their initial resting configuration, however that the microswitch 16 returns itself to its first state.

Il en est de même si, comme représenté sur la figure 10, le mur 27 porte un revêtement 35 formant une surface d'appui 30' pour la plaque 14 autour du support 13.The same applies if, as shown in FIG. 10, the wall 27 carries a coating 35 forming a bearing surface 30 'for the plate 14 around the support 13.

Mais, dans ce cas, la sortie de la tige filetée 12B par rapport au manchon 12A en configuration de repos est plus accentuée, cependant que, pour cette configuration de repos, le manchon 12A est à la même distance de l'ergot 17 du microrupteur 16 que précédemment.But, in this case, the output of the threaded rod 12B relative to the sleeve 12A in the rest configuration is more accentuated, however, for this rest configuration, the sleeve 12A is at the same distance from the lug 17 of the microswitch 16 than before.

Lorsque la touche de manoeuvre 15 est basculée, l'action sur l'ergot 17 de ce microrupteur 16 se déroule donc exactement comme dans le cas précédent.When the operating button 15 is switched, the action on the lug 17 of this microswitch 16 therefore takes place exactly as in the previous case.

Autrement dit, le fonctionnement de l'appareil électrique 10 suivant l'invention est indifférent à l'épaisseur du revêtement 35 éventuellement présent sur le mur 27.In other words, the operation of the electrical device 10 according to the invention is indifferent to the thickness of the coating 35 possibly present on the wall 27.

Bien entendu, la présente invention ne se limite pas à la forme de réalisation décrite et représentée, notamment en ce qui concerne le nombre de filets de la tige filetée du poussoir suivant l'invention et/ou le profil de ces filets, mais englobe toute variante d'exécution.Of course, the present invention is not limited to the embodiment described and shown, in particular as regards the number of threads of the threaded rod of the pusher according to the invention and / or the profile of these threads, but encompasses any variant.

Il pourrait suffire, en particulier, que la tige filetée comporte au moins un filet.It could be sufficient, in particular, that the threaded rod has at least one thread.

En outre, au lieu d'agir indirectement sur le poussoir, par l'intermédiaire d'un levier, la touche de manoeuvre pourrait tout aussi bien agir directement sur celui-ci.In addition, instead of acting indirectly on the pusher, by means of a lever, the operating button could just as easily act directly on it.

Enfin, au lieu d'être montée pivotante sur la plaque qui la porte, cette touche de manoeuvre pourrait tout aussi bien être par exemple mobile axialement en translation par rapport à celle-ci.Finally, instead of being pivotally mounted on the plate which carries it, this operating key could just as easily be, for example, movable axially in translation relative to the latter.
