Abstract

The mechanism has an actuating unit (4) sliding between advanced and remote positions. A connecting rod (21) has a slide (35) moved on a cam surface (37), and a central block (40) emerges from the cam surface. A cam channel is formed around the island and has two paths for the slide, where the channel is flat. A backstop unit blocks access of the slide to one of the paths, and has a spring branch (67) extending transversal to the channel at a junction between the paths in case of absence of stress on the slide. An independent claim is also included for an electrical control device comprising a mechanism for connecting and electrically insulating terminals.

Description

L'invention concerne de manière générale les mécanismes à deux positions stables.The invention generally relates to mechanisms with two stable positions.

L'invention concerne plus particulièrement un mécanisme qui comporte un organe d'actionnement adapté à coulisser selon une direction de coulissement entre une position reculée et une position avancée et qui est adapté à maintenir l'organe dans la position avancée après une action de coulissement dans le sens position reculée vers position avancée, exercée sur l'organe lorsqu'il est dans sa position reculée, et à le maintenir dans sa position reculée après une action de coulissement similaire exercée sur l'organe lorsque celui-ci est dans sa position avancée.The invention relates more particularly to a mechanism which comprises an actuating member adapted to slide in a direction of sliding between a retracted position and an advanced position and which is adapted to maintain the organ in the advanced position after a sliding action in the direction retracted position to advanced position, exerted on the body when it is in its retracted position, and to maintain it in its retracted position after a similar sliding action exerted on the body when it is in its advanced position .

ARRIERE PLAN TECHNOLOGIQUEBACKGROUND TECHNOLOGY

On trouve ce type de mécanismes dans de nombreuses applications par exemple les fermetures de porte ou de couvercle ou encore dans le domaine des organes de commutation électrique dont la commande s'effectue par appuis successifs sur l'organe d'actionnement. Ce type de mécanisme, lorsqu'il est utilisé dans un dispositif de commande électrique comportant des bornes, permet de relier celles-ci ou de les isoler électriquement en commandant le positionnement de l'organe dans la position reculée ou la position avancée.This type of mechanism is found in many applications, for example door or lid closures or in the field of electrical switching members whose control is effected by successive presses on the actuating member. This type of mechanism, when used in an electrical control device having terminals, allows to connect them or electrically isolate them by controlling the positioning of the body in the retracted position or the advanced position.

On connaît en particulier un tel mécanisme dont l'organe est entraîné à coulissement par un circuit magnétique formé d'une bobine dont une armature est mobile et reliée à l'organe. Ce mécanisme comporte une biellette montée à pivotement sur l'organe. Cette biellette présente une extrémité libre recourbée formant un curseur. Le mécanisme comporte également une came en coeur présentant un îlot autour duquel s'étend un chemin de came dans lequel le curseur est adapté à se déplacer d'une position reculée à une position avancée et inversement.In particular, such a mechanism is known in which the member is slidably driven by a magnetic circuit formed of a coil whose armature is movable and connected to the member. This mechanism comprises a link pivotally mounted on the member. This link has a curved free end forming a slider. The mechanism also comprises a core cam having an island around which extends a cam path in which the cursor is adapted to move from a retracted position to an advanced position and vice versa.

Le cheminement du curseur autour de l'îlot se décompose en un premier trajet entre la position reculée et la position avancée et un second trajet, distinct du premier trajet, entre la position avancée et la position reculée.The path of the cursor around the island is broken down into a first path between the retracted position and the advanced position and a second path, distinct from the first path, between the advanced position and the retracted position.

Le curseur est soumis à une sollicitation pour le contraindre à cheminer dans le sens voulu.The cursor is subjected to a solicitation to force him to walk in the desired direction.

Il est prévu des moyens anti-retour pour éviter que le curseur, en position reculée, n'entame son cheminement par le mauvais trajet. Ces moyens anti-retour comportent un ressort qui sollicite le curseur contre la surface de came, cette surface présentant un cran en toit d'usine situé à la jonction des deux trajets.There are provided anti-return means to prevent the cursor, in the retracted position, begins its journey by the wrong path. These non-return means comprise a spring which urges the slider against the cam surface, this surface having a factory roof at the junction of the two paths.

En fin de second trajet, le curseur s'élève grâce à la face inclinée du cran jusqu'à atteindre le sommet après quoi le curseur se retrouve sur le premier trajet en position reculée, contre la face droite du cran qui empêche le curseur de s'engager dans le second trajet.At the end of the second path, the cursor rises thanks to the inclined face of the notch until reaching the vertex after which the cursor is found on the first path in the retracted position, against the right face of the notch which prevents the cursor from s engage in the second journey.

Cette solution permettant d'engager le curseur sur le bon trajet en sollicitant le curseur selon la direction transversale et vers la surface de came donne satisfaction. Néanmoins la biellette étant une fine tige de métal et la came étant réalisée en matière plastique, celle-ci s'use d'autant plus que la tige est sollicitée vers elle. Et il en résulte des frottements que doit vaincre le circuit magnétique pour permettre un cheminement satisfaisant du curseur.This solution to engage the cursor on the right path by requesting the cursor in the transverse direction and to the cam surface gives satisfaction. Nevertheless, the connecting rod being a thin metal rod and the cam being made of plastic material, the latter wears all the more as the rod is urged towards it. And this results in friction that must overcome the magnetic circuit to allow a satisfactory path of the cursor.

La détermination d'une géométrie adaptée de l'extrémité libre du curseur aide à concilier la nécessité de frottements importants pour assurer le blocage anti-retour et les inconvénients procurés par les frottements pour le déplacement du curseur dans le chemin de came mais cela nécessite un difficile usinage de l'extrémité d'une tige fine.The determination of a geometry adapted to the free end of the slider helps to reconcile the need for significant friction to ensure the anti-return blocking and disadvantages provided by the friction for the displacement of the slider in the cam path but this requires a difficult machining the end of a thin rod.

A cet effet, l'invention propose un mécanisme selon la revendication 1,For this purpose, the invention proposes a mechanism according to claim 1,

Ainsi la permanence du contact entre la surface de came et le curseur n'est pas impérative de sorte que les contraintes de géométrie de l'extrémité du curseur sont modérées.

On the other hand, the absence of strong pressure against the cam surface ensures a better longevity of the mechanism.

DESCRIPTION DETAILLEE D'UN EXEMPLE DE REALISATIONDETAILED DESCRIPTION OF AN EXEMPLARY EMBODIMENT

La figure 1 montre un dispositif de commande électrique susceptible d'être commandé à distance par des impulsions électriques. Dans le présent exemple, il s'agit d'un télérupteur 1 qui est modulaire, c'est-à-dire sous une forme générale plate et dont l'épaisseur est multiple d'un module déterminé. Cela permet au télérupteur 1 d'être disposé côte à côte sur un même support avec d'autres appareils électriques modulaires de même format.The figure 1 shows an electrical control device that can be controlled remotely by electrical pulses. In the present example, it is a remote switch 1 which is modular, that is to say in a generally flat shape and whose thickness is multiple of a specific module. This allows the remote switch 1 to be placed side by side on the same support with other modular electrical devices of the same format.

Le télérupteur 1 comporte un boîtier comprenant un corps de boîtier 2 et un capot (non représenté) convenablement solidarisés l'un à l'autre.The remote control 1 comprises a housing comprising a housing body 2 and a cover (not shown) properly secured to one another.

De manière connue en soit, le télérupteur 1 comporte dans le boîtier un circuit magnétique de commande présentant une bobine 3 adaptée à recevoir des impulsions électriques, et, commandé par ce circuit magnétique, suivant des modalités décrites ci-après, un organe d'actionnement 4.In a manner known per se, the remote control 1 comprises in the housing a control magnetic circuit having a coil 3 adapted to receive electrical pulses, and controlled by this magnetic circuit, in the manner described below, an actuating member. 4.

La bobine 3 comporte un bloc central 5 fixe globalement rectangulaire présentant une partie creuse en son centre. Sur sa périphérie, le bloc 5 présente un bobinage de fil conducteur (non représenté). La bobine 3 comporte en outre une armature fixe 6 et une armature mobile 7 disposées sur chaque côté du bloc 5 présentant une ouverture sur la partie creuse. Ces deux armatures 6, 7 présentent une même forme en E couché avec trois branches 8 parallèles. Chaque branche 8 d'une armature 6, 7 est disposée en vis-à-vis d'une branche 8 de l'autre armature 7, 6.The coil 3 comprises a central block 5 fixed generally rectangular having a hollow portion at its center. On its periphery, block 5 has a coil of conductive wire (not shown). The coil 3 further comprises a fixed armature 6 and a movable armature 7 disposed on each side of the block 5 having an opening on the hollow portion. These two frames 6, 7 have the same shape E coated with three parallel branches 8. Each branch 8 of an armature 6, 7 is disposed facing a branch 8 of the other armature 7, 6.

La branche 8 centrale de l'armature fixe 6 est entièrement insérée dans la partie creuse du bloc 5. La branche 8 centrale de l'armature mobile 7 est partiellement engagée dans la partie creuse du bloc 5.The central branch 8 of the fixed armature 6 is fully inserted into the hollow part of the block 5. The central arm 8 of the mobile armature 7 is partially engaged in the hollow part of the block 5.

L'armature 7 est mobile en translation selon une direction de coulissement parallèle à la direction principale des branches 8.The armature 7 is movable in translation in a direction of sliding parallel to the main direction of the branches 8.

La bobine 3 comporte en outre un support d'arbre 9 disposé au niveau d'un côté du bloc 5 présentant une ouverture sur la partie creuse. Le support 9 est solidaire d'une paroi 10 fixée sur le bloc 5.The coil 3 further comprises a shaft support 9 disposed at one side of the block 5 having an opening on the hollow portion. The support 9 is secured to a wall 10 fixed on the block 5.

Ce support 9 est destiné à accueillir un arbre 11 appartenant à une manette 12 formée d'une coque 13 s'étendant partiellement autour d'une portion de l'armature mobile 7. Sur un côté opposé au support d'arbre 9, la manette 12 présente un bouton 14 qui saille hors du corps 2 par une ouverture rectangulaire prévue à cet effet. Ce bouton 14 est destiné à l'actionnement manuel du télérupteur 1.This support 9 is intended to accommodate a shaft 11 belonging to a handle 12 formed of a shell 13 extending partially around a portion of the mobile armature 7. On a side opposite the shaft support 9, the joystick 12 has a button 14 which protrudes out of the body 2 by a rectangular opening provided for this purpose. This button 14 is intended for the manual actuation of the remote control 1.

A l'opposé du bouton 14, la manette 12 présente une paroi en saillie pourvue d'une découpe 15 en U avec le fond de la découpe 15 qui est arrondi. Cette découpe 15 est destinée à recevoir un doigt cylindrique 20 décrit ci-après.Opposite the button 14, the lever 12 has a projecting wall provided with a cutout 15 in U with the bottom of the cutout 15 which is rounded. This cutout 15 is intended to receive a cylindrical finger 20 described below.

La manette 12 comporte également un barreau non représenté qui s'étend entre deux parois de la coque 13. Le barreau est situé sous le bouton 14. La manette 12 et l'armature mobile 7 sont liées l'une de l'autre, de façon relâchée c'est-à-dire avec du jeu, du fait que le barreau est placé dans un orifice 16 de section globalement oblongue prévu dans la base de l'armature mobile 7 de sorte que les déplacements de la manette 12 s'effectuent en relation avec les déplacements de l'armature mobile 7. L'arbre 11 est situé à mi-chemin entre le barreau et la découpe 15.The lever 12 also comprises a not shown bar which extends between two walls of the shell 13. The bar is located under the button 14. The lever 12 and the moving armature 7 are connected to each other, relaxed manner that is to say with play, because the bar is placed in an orifice 16 of generally oblong section provided in the base of the movable armature 7 so that the movements of the lever 12 are made in relationship with displacements of the movable armature 7. The shaft 11 is situated midway between the bar and the cutout 15.

On décrit maintenant les déplacements de l'armature mobile 7 et de la manette 12 à partir de l'agencement illustré sur la figure 1. Selon cet agencement, l'armature mobile 7 et la manette 12 sont chacun dans une position dénommée ci-après position de repos.The displacements of the mobile armature 7 and the lever 12 are now described from the arrangement shown in FIG. figure 1 . According to this arrangement, the movable armature 7 and the lever 12 are each in a position hereinafter referred to as the rest position.

A la réception d'une impulsion électrique par la bobine 3, l'armature 7, mobile en translation, est attirée selon la direction de coulissement vers l'armature fixe 6. Le barreau de la manette 12 étant placé dans l'orifice 16, celui-ci est entraîné avec l'armature 7 vers l'armature 6. Comme l'arbre 11 est reçu dans le support 9, la portion de manette 12 qui ne comporte pas le barreau est entraînée à rotation vers l'extérieur du corps 2, avec la découpe 15 qui est entraînée selon la direction de coulissement vers le haut du corps 2, c'est-à-dire la partie du corps 2 qui présente l'ouverture permettant le passage du bouton 14. On définit le haut et le bas comme le haut et le bas du télérupteur 1 tel que représenté sur la figure 1.On receipt of an electrical pulse by the coil 3, the armature 7, mobile in translation, is attracted in the direction of sliding towards the fixed armature 6. The bar of the lever 12 being placed in the orifice 16, it is driven with the frame 7 towards the frame 6. As the shaft 11 is received in the support 9, the handle portion 12 which does not include the bar is driven to rotate outwardly of the body 2 , with the cutout 15 which is driven in the direction of sliding up the body 2, that is to say the portion of the body 2 which has the opening for the passage of the button 14. It defines the top and the low as the top and the bottom of the remote control 1 as shown on the figure 1 .

Lorsque l'armature mobile 7 est en fin de course, les branches 8 de l'armature 7 et celles de l'armature 6 sont en contact deux à deux. L'armature 7 et la manette 12 sont alors chacune dans une position dénommée ci-après position de travail.When the movable armature 7 is at the end of the stroke, the arms 8 of the armature 7 and those of the armature 6 are in contact two by two. The armature 7 and the lever 12 are then each in a position hereinafter called working position.

Lorsque l'impulsion s'arrête, l'armature 7 effectue le mouvement inverse et se déplace, tout comme la manette 12, de la position de travail vers la position de repos.When the pulse stops, the armature 7 performs the reverse movement and moves, like the lever 12, from the working position to the rest position.

On décrit maintenant l'organe d'actionnement 4. Celui-ci s'étend sur une grande partie de la hauteur du corps de boîtier 2 et s'étend principalement en regard de la face intérieure du corps de boîtier 2. L'organe 4 s'étend globalement, et est mobile à coulissement, selon la direction de coulissement.The actuating member 4 is now described. It extends over a large part of the height of the casing body 2 and extends mainly opposite the inside face of the casing body 2. The body 4 extends generally, and is slidably movable, according to the sliding direction.

A son extrémité située vers le haut du corps 2, l'organe 4 présente un doigt cylindrique 20 adapté à être reçu dans la découpe 15. A l'écart du doigt 20, l'organe 4 présente un orifice cylindrique de petit diamètre adapté à accueillir l'extrémité d'une biellette 21 de section circulaire.At its end located towards the top of the body 2, the member 4 has a cylindrical finger 20 adapted to be received in the cutout 15. Away from the finger 20, the member 4 has a cylindrical orifice of small diameter adapted to accommodate the end of a rod 21 of circular section.

A son extrémité opposée qui s'étend vers le bas du corps de boîtier 2, c'est-à-dire du côté opposé au bouton 14, l'organe 4 est solidaire d'un tronçon de tube 22. Ce tronçon 22 présente quatre parois rectangulaires disposées globalement à angle droit qui délimitent un espace parallélépipédique. Ce tronçon 22 est raccordé au reste de l'organe 4 par un pontet non représenté. Une paroi 26 du corps de boîtier 2 s'étend entre le tronçon 22 et le reste de l'organe 4. La paroi 26 présente une découpe 27 adaptée à permettre le passage du pontet. Cela permet au pontet et donc au tronçon 22 de pouvoir coulisser selon la direction de coulissement avec le reste de l'organe 4.At its opposite end which extends downwardly from the casing body 2, that is to say on the opposite side to the button 14, the member 4 is integral with a section of tube 22. This section 22 has four rectangular walls arranged generally at right angles which delimit a parallelepiped space. This section 22 is connected to the rest of the member 4 by a not shown bridge. A wall 26 of the housing body 2 extends between the section 22 and the remainder of the member 4. The wall 26 has a cutout 27 adapted to allow the passage of the bridge. This allows the bridge and thus the section 22 to slide in the direction of sliding with the rest of the member 4.

Ce tronçon 22 forme pour une platine 25 un guide à translation selon la direction de coulissement. Cette platine 25 est disposée transversalement à la direction de coulissement. La platine 25 est globalement rectangulaire. Sur sa portion disposée dans le tronçon 22, elle présente une largeur équivalente à la largeur intérieure entre les deux parois longitudinales opposées. Elle présente une largeur légèrement supérieure sur les portions adjacentes de sorte la platine 25 est bloquée à translation selon une direction parallèle à sa longueur.This section 22 forms for a plate 25 a guide to translation in the direction of sliding. This plate 25 is disposed transversely to the direction of sliding. The plate 25 is generally rectangular. On its portion disposed in the section 22, it has a width equivalent to the internal width between the two opposite longitudinal walls. It has a slightly greater width on the adjacent portions so that the plate 25 is locked in translation in a direction parallel to its length.

Un ressort (non représenté) est disposé entre le fond du tronçon 22 et la platine 25 de façon notamment à solliciter la platine 25 vers le haut du tronçon 22.A spring (not shown) is disposed between the bottom of the section 22 and the plate 25 so as in particular to urge the plate 25 up the section 22.

A chaque extrémité de la platine 25 sont fixés des contacts conducteurs 30 et le corps de boîtier 2 est pourvu de bornes 31 avec lesquelles les contacts 30 sont adaptés à coopérer. Les bornes 31 sont placées sur des parois fixes du corps de boîtier 2. Chaque borne 31 est adaptée à coopérer avec l'un des deux contacts 30 de sorte que, lorsque chaque contact 30 est positionné contre la borne 31 correspondante, les deux bornes 31 sont reliées électriquement. Cette position des contacts 30 correspond à la position avancée de l'organe 4. Et lorsque chaque contact 30 est à l'écart de la borne 31 correspondante, ces bornes 31 sont isolées électriquement. Cette position des contacts 30 correspond à la position reculée de l'organe 4.At each end of the plate 25 are fixed conductive contacts 30 and the housing body 2 is provided with terminals 31 with which the contacts 30 are adapted to cooperate. The terminals 31 are placed on fixed walls of the housing body 2. Each terminal 31 is adapted to cooperate with one of the two contacts 30 so that, when each contact 30 is positioned against the corresponding terminal 31, the two terminals 31 are electrically connected. This position of the contacts 30 corresponds to the advanced position of the member 4. And when each contact 30 is away from the corresponding terminal 31, these terminals 31 are electrically isolated. This position of the contacts 30 corresponds to the retracted position of the member 4.

La biellette 21 est une tige de métal dont les deux extrémités sont recourbées transversalement. La première extrémité est insérée dans l'orifice de l'organe 4, tandis que l'autre extrémité est libre. Celle-ci forme un curseur 35 adapté à se déplacer dans le chemin de came d'un dispositif généralement appelé came en coeur 36. La came en coeur 36 appartient à une paroi fixe du corps de boîtier 2. Elle comporte une surface de came 37 plane et globalement rectangulaire. Deux excroissances formant un mur latéral 38 et un mur latéral 39 s'étendent à l'écart l'une de l'autre sur toute la hauteur de la surface de came 37. Ces murs 38, 39 sont situés de part et d'autre d'un îlot central 40 et émergent perpendiculairement à la surface de came 37.The link 21 is a metal rod whose two ends are bent transversely. The first end is inserted into the orifice of the member 4, while the other end is free. This forms a cursor 35 adapted to move in the cam path of a device generally called core cam 36. The core cam 36 is part of a fixed wall of the housing body 2. It has a planar cam surface 37 and generally rectangular. Two protuberances forming a lateral wall 38 and a lateral wall 39 extend apart from each other over the entire height of the cam surface 37. These walls 38, 39 are located on either side of a central island 40 and emerge perpendicularly to the cam surface 37.

Chaque mur 38, 39 présente deux portions séparées par un décrochement.Each wall 38, 39 has two portions separated by a recess.

Le mur latéral 38 présente sur sa partie extrême haute une épaisseur équivalente à celle de l'îlot 40. Le reste du mur 38 présente une épaisseur moindre avec le décrochement 42 qui sépare ces deux portions de mur 38.The side wall 38 has on its upper end a thickness equivalent to that of the island 40. The remainder of the wall 38 has a lower thickness with the recess 42 which separates these two wall portions 38.

Le mur latéral 39 présente sur son tiers bas une épaisseur équivalente à celle du reste du mur 38 tandis que le reste du mur 39 présente une épaisseur équivalente à celle de l'îlot 40 avec le décrochement 43 qui sépare ces deux portions de mur 39.The side wall 39 has on its lower third a thickness equivalent to that of the rest of the wall 38 while the rest of the wall 39 has a thickness equivalent to that of the island 40 with the recess 43 which separates these two wall portions 39.

Les murs latéraux 38, 39 forment des parois de guidage permettant au curseur 35 d'être déplacé sur le long du chemin de came sans risquer d'en sortir latéralement.The side walls 38, 39 form guide walls allowing the slider 35 to be moved along the cam path without the risk of coming out laterally.

Les épaisseurs sont mesurées à partir de la surface de came 37 et perpendiculairement à celle-ci.The thicknesses are measured from the cam surface 37 and perpendicular to it.

L'îlot central 40 saille perpendiculairement à la surface de came 37 entre les murs latéraux 38, 39 et sensiblement au centre de la surface de came 37. Sa section est celle d'un triangle dont l'un des côtés est remplacé par une courbe de convexité tournée vers l'intérieur du triangle.The central island 40 protrudes perpendicularly to the cam surface 37 between the side walls 38, 39 and substantially in the center of the cam surface 37. Its section is that of a triangle of which one of the sides is replaced by a curve of convexity turned towards the interior of the triangle.

L'îlot 40 présente trois tranches latérales 49, 50, 51. Les deux tranches 49, 50 sont des tranches obliques présentant à leur jonction un sommet commun 48. Elles forment un V dont la pointe est représentée par le sommet 48. Les tranches 49, 50 s'étendent vers le haut et respectivement vers le mur latéral 38 et vers le mur latéral 39.The island 40 has three lateral slices 49, 50, 51. The two slices 49, 50 are oblique slices having at their junction a common vertex 48. They form a V whose tip is represented by the vertex 48. The slices 49 50 extend upwards and respectively to the side wall 38 and to the side wall 39.

La dernière tranche 51, ou anse 51 définit un renfoncement permettant la réception du curseur 35 comme exposé plus loin.The last slice 51, or handle 51 defines a recess allowing the reception of the slider 35 as explained below.

L'îlot central 40 comporte en outre un pion 56 qui s'étend en saillie au-dessus du reste de l'îlot central 40. Le pion 56 présente une section oblongue et s'étend le long de la tranche 49 de telle sorte que l'un de ses deux côtés rectilignes s'étend dans le prolongement de la tranche 49.The central island 40 further comprises a pin 56 which protrudes above the remainder of the central island 40. The pin 56 has an oblong section and extends along the edge 49 so that one of its two straight sides extends in the extension of the slice 49.

Face à l'îlot central 40 qui émerge de la surface de came 37, émerge une péninsule 45 dont l'épaisseur correspond à celle de l'îlot 40 à l'exception du pion 56.Facing the central island 40 which emerges from the cam surface 37, a peninsula 45 emerges, the thickness of which corresponds to that of the island 40 except for the pawn 56.

En ce qui concerne la péninsule 45, celle-ci est disposée sur l'un des bords de la surface de came 37. Elle comporte une pointe dirigée vers l'anse 51. La péninsule 45 présente une première tranche oblique 52 orientée sensiblement parallèlement à la tranche 50 de l'îlot 40. La deuxième tranche 53 de la péninsule 45 forme avec la tranche 52 la pointe susmentionnée. Cette tranche 53 est reliée à l'extrémité de la tranche 52 et est disposée obliquement dans une direction sensiblement parallèle à la tranche 49 sur une première portion. La tranche 53 se prolonge par une portion s'étendant dans la direction de coulissement.Regarding the peninsula 45, the latter is disposed on one of the edges of the cam surface 37. It has a point directed towards the handle 51. The peninsula 45 has a first oblique slice 52 oriented substantially parallel to block 50 of block 40. The second section 53 of peninsula 45 forms the aforementioned point with section 52. This wafer 53 is connected to the end of wafer 52 and is arranged obliquely in a direction substantially parallel to wafer 49 on a first portion. The wafer 53 is extended by a portion extending in the direction of sliding.

La péninsule 45 présente en outre, de part et d'autre de la pointe formée par les tranches 52, 53, deux tranches de fond 54, 55 disposées transversalement à la direction de coulissement.Peninsula 45 also has, on either side of the point formed by the slices 52, 53, two bottom slices 54, 55 arranged transversely to the direction of sliding.

La tranche 54 est adjacente à la tranche 52 de la péninsule 46 et adjacente au mur latéral 39 tandis que la tranche 55 est adjacente à la tranche 53 de la péninsule 46 et au mur latéral 38.The slice 54 is adjacent to the slice 52 of the peninsula 46 and adjacent to the side wall 39 while the slice 55 is adjacent to the slice 53 of the peninsula 46 and the side wall 38.

La zone située en vis-à-vis du décrochement 43 et au bord du chemin de came présente un doigt d'enroulement 60 globalement cylindrique. Le doigt 60 présente une découpe 61 selon un plan parallèle à l'axe du doigt 60 à l'écart de cet axe. La découpe 61 s'étend sur une portion supérieure du doigt 60.The zone located opposite the recess 43 and at the edge of the cam path has a generally cylindrical winding pin 60. The finger 60 has a cutout 61 in a plane parallel to the axis of the finger 60 away from this axis. The cutout 61 extends over an upper portion of the finger 60.

Le doigt 60 est adapté à recevoir un ressort en compas 65, ou ressort en épingle à cheveux, comportant une première branche rectiligne 66 et une deuxième branche rectiligne 67. Le doigt 60 et notamment la découpe 61 sont également adaptés pour servir de moyens d'emboîtement d'un capot du boîtier pour refermer le corps 2.The finger 60 is adapted to receive a spring 65, or hairpin spring, having a first rectilinear branch 66 and a second rectilinear branch 67. The finger 60 and in particular the cutout 61 are also adapted to serve as means for interlocking a housing cover to close the body 2.

Le ressort 65 est réalisé d'une pièce avec les deux branches 66, 67 qui sont reliées l'une à l'autre par un noyau enroulé 68. Ce noyau s'enroule autour du doigt 60 et est enfoncé sur le doigt 60 de façon à ce que le ressort 65 soit emboîté sur ce doigt 60.The spring 65 is made in one piece with the two branches 66, 67 which are connected to one another by a wound core 68. This core winds around the finger 60 and is pressed on the finger 60 so that the spring 65 is fitted on this finger 60.

La deuxième branche 67 est située à une distance de la surface de came 37 inférieure à celle qui sépare la première branche 66 de la surface de came 37 avec la différence de distances qui correspond à la hauteur du noyau 68.The second branch 67 is located at a distance from the cam surface 37 less than that which separates the first branch 66 from the cam surface 37 with the difference in distances which corresponds to the height of the core 68.

Le ressort 65 en l'absence de sollicitations est dans sa position de repos et il est disposé de telle sorte que la première branche 66 est positionnée contre le pion 56 du côté de l'anse 51. La première branche 66 s'étend transversalement au chemin de came et son extrémité s'étend au-delà du chemin de came en passant au-dessus de la marche 42. Son extrémité libre est située au-delà du mur latéral 38.The spring 65 in the absence of stresses is in its rest position and is arranged such that the first branch 66 is positioned against the pin 56 on the side of the handle 51. The first branch 66 extends transversely to the cam path and its end extends beyond the cam path passing over the step 42. Its free end is located beyond the side wall 38.

La deuxième branche 67, en position de repos, est disposée contre la tranche 49 de l'îlot 40. Elle s'étend transversalement au chemin de came et est orientée en direction de l'extrémité de la première branche 66. L'extrémité libre de la deuxième branche 67 est située à proximité de la marche 42.The second branch 67, in the rest position, is disposed against the edge 49 of the island 40. It extends transversely to the cam path and is oriented toward the end of the first branch 66. The free end of the second branch 67 is located near the step 42.

On décrit maintenant le circuit selon lequel est adapté à se déplacer le curseur 35 dans le chemin de came. Le curseur 35 se déplace entre quatre positions principales : une position reculée (figure 3), une première positon intermédiaire (figure 4), une position avancée (figure 5) et une deuxième position intermédiaire (figure 6). Après cette dernière, le curseur 35 retrouve la position reculée initiale.The circuit according to which is adapted to move the cursor 35 in the cam path is now described. The cursor 35 moves between four main positions: a retracted position ( figure 3 ), a first intermediate position ( figure 4 ), an advanced position ( figure 5 ) and a second intermediate position ( figure 6 ). After the latter, the cursor 35 returns to the initial retracted position.

Dans sa position reculée, le curseur 35 est disposé contre le mur 39 légèrement à l'écart du sommet 48 de l'îlot 40. Dans la première position intermédiaire, le curseur 35 est disposé contre la tranche 52 à l'écart de la tranche 54. Dans sa position avancée, le curseur est disposé dans l'anse 51. Et dans la deuxième position intermédiaire, le curseur 35 est disposé contre le mur 38 à l'écart de la tranche 55.In its retracted position, the slider 35 is disposed against the wall 39 slightly away from the top 48 of the island 40. In the first intermediate position, the slider 35 is disposed against the slice 52 away from the slice 54. In its advanced position, the slider is arranged in the handle 51. And in the second intermediate position, the slider 35 is disposed against the wall 38 away from the slice 55.

On décrit maintenant un cycle complet du curseur 35.We now describe a complete cycle of the cursor 35.

Initialement, l'armature mobile 7 et la manette 12 sont dans leur position de repos et l'organe 4 et le curseur 35 sont chacun dans leur position reculée de sorte que les contacts 30 sont à l'écart des bornes 31 correspondantes.Initially, the movable armature 7 and the lever 12 are in their rest position and the member 4 and the slider 35 are each in their retracted position so that the contacts 30 are away from the corresponding terminals 31.

Sous l'effet d'une impulsion électrique aux bornes de la bobine 3, l'armature 7 passe en position de travail tout comme la manette 12 qui est alors entraînée en rotation. Par l'intermédiaire de la découpe 15 et du doigt 20, l'organe 4 coulisse selon la direction de coulissement (direction position reculée vers position avancée) vers sa position avancée.Under the effect of an electrical pulse across the coil 3, the armature 7 passes to the working position as the lever 12 which is then rotated. Via the cutout 15 and the finger 20, the member 4 slides in the sliding direction (direction retracted position to advanced position) to its advanced position.

Au niveau de la came 36, cela se traduit par le déplacement du curseur 35 le long d'un premier trajet. La configuration du ressort sur la came 36 est telle que dans sa position de repos, la branche 67 est en butée contre la tranche 49 de l'îlot 40. Le curseur est lui positionné contre le mur 39 en vis-à-vis selon la direction de coulissement de la tranche 50 de l'îlot 40. La branche 67 bloque donc l'accès au passage situé entre la tranche 49 et le mur 38. Ainsi, le curseur 35 ne peut que s'engager dans le passage délimité par la tranche 50 et le mur 39. Il chemine alors obliquement vers la tranche 54, contre la tranche 50, entre cette tranche 50 de l'îlot 40 et le mur 39. A mi-chemin de la tranche 50, le curseur 35 rencontre la branche 66 du ressort 65. Le curseur 35 sollicite alors la branche 66 en déroulement de celle-ci de sorte que l'angle formé par les deux branches 66, 67 s'ouvre progressivement avec l'avancée du curseur 35. Lorsque celui-ci atteint l'extrémité de la tranche 50, la branche 66 s'étend en direction de la tranche 54 ce qui correspond à son état déroulé maximal. Le curseur 35 n'étant ensuite plus contraint par l'îlot 40, il est sollicité par la branche 66 vers la tranche 52 qu'il remonte jusqu'à s'arrêter légèrement à l'écart de la tranche 54. Dans cette première position intermédiaire du curseur 35, l'organe 4 est situé plus haut que dans sa position reculée et que dans sa position avancée.At the cam 36, this results in the cursor moving along a first path. The configuration of the spring on the cam 36 is such that in its rest position, the branch 67 abuts against the edge 49 of the island 40. The slider is positioned against the wall 39 facing each other according to the sliding direction of the slice 50 of the island 40. The branch 67 blocks the access to the passage located between the slice 49 and the wall 38. Thus, the slider 35 can only engage in the passage delimited by the slice 50 and the wall 39. It then runs obliquely to the slice 54, against the slice 50, between this slice 50 of the island 40 and the wall 39. Halfway of the slice 50, the slider 35 meets the branch 66 of the spring 65. The slider 35 then urges the branch 66 unwinding thereof so that the angle formed by the two branches 66, 67 gradually opens with the advance of the slider 35. When it reaches the end of the slice 50, the branch 66 extends towards the slice 54 which corresponds to its current state maximum. The slider 35 is then no longer constrained by the island 40, it is biased by the branch 66 to the slice 52 it goes up to stop slightly away from the slice 54. In this first position intermediate slider 35, the member 4 is located higher than in its retracted position and in its advanced position.

Simultanément à ce cheminement du curseur 35 sur cette portion de premier trajet, le tronçon 22 a coulissé vers le haut selon la direction de coulissement et sous l'effet du ressort qu'il porte, la platine 25 a également coulissé selon cette même direction. La course de l'organe 4 et donc du tronçon 22 étant plus importante que la distance séparant la platine 25 en position reculée de l'organe 4 des bornes 31, les contacts 30 viennent en contact des bornes 31 avant que l'organe 4 n'ait terminé sa course. Entre la mise en contact des contacts 30 et des bornes 31 et la fin de la course du tronçon 22, le ressort s'écrase progressivement pour rattraper cette différence de distance et sollicite continûment le contact entre les contacts 30 et les bornes 31.Simultaneously with this path of the cursor 35 on this portion of the first path, the section 22 has slid upwards in the direction of sliding and under the effect of the spring that it carries, the plate 25 also slid in the same direction. The stroke of the member 4 and thus of the section 22 being larger than the distance separating the plate 25 in the retracted position of the member 4 of the terminals 31, the contacts 30 come into contact with the terminals 31 before the member 4 finished his race. Between the contacting of the contacts 30 and the terminals 31 and the end of the stroke of the section 22, the spring crushes progressively to make up this difference in distance and continuously solicits the contact between the contacts 30 and the terminals 31.

Tant que l'impulsion se produit, le curseur 35 reste en position contre la tranche 52 dans sa première position intermédiaire (figure 4) avec un léger jeu par rapport à la tranche de fond 54. Ce jeu permet d'éviter que le curseur 35 ne vienne en butée contre la paroi de fond 54 avant que les armatures 6, 7 ne soient en contact l'une contre l'autre. Dès que l'impulsion s'arrête, l'armature 7 et la manette 12 formant moyens de rappel reviennent vers leur position de repos et l'organe 4 est entraîné, sans l'atteindre vers sa position reculée. Le curseur 35 est alors entraîné vers le bas. Sur cette portion de son premier trajet, le curseur 35 est sollicité en rotation dans le sens anti-horaire (par rapport à l'îlot, la biellette 21 est elle sollicitée dans le sens horaire) de sorte que le curseur 35 se déplace vers l'îlot 40 le long de la tranche 52 de la péninsule 45 jusqu'à venir en butée contre l'anse 51. Il est pris dans le creux de l'anse 51 dans sa position avancée, qui est une position stable (figure 5). La branche 66 n'a pas retrouvé sa position de repos. Elle est alignée avec la portion oblique de la tranche 53 de la péninsule 45.As long as the pulse occurs, the slider 35 remains in position against the slice 52 in its first intermediate position ( figure 4 ) with a slight clearance with respect to the bottom wafer 54. This clearance prevents the slider 35 from abutting against the bottom wall 54 before the armatures 6, 7 are in contact against each other. 'other. As soon as the pulse stops, the armature 7 and the lever 12 forming return means return to their rest position and the member 4 is driven, without reaching to its retracted position. The cursor 35 is then driven down. On this portion of its first path, the slider 35 is biased in counter-clockwise rotation (relative to the island, the rod 21 is urged in the clockwise direction) so that the slider 35 moves towards the island 40 along the edge 52 of the peninsula 45 until it comes to a stop against the handle 51. It is caught in the hollow of the handle 51 in its advanced position, which is a stable position ( figure 5 ). Branch 66 has not returned to its resting position. It is aligned with the oblique portion of Unit 53 of Peninsula 45.

Simultanément à ce cheminement du curseur 35 sur cette portion de premier trajet, le tronçon 22 a coulissé vers le bas selon la direction longitudinal. Le curseur n'ayant globalement parcouru que la moitié de la course précédente, le tronçon 22 n'a pas non plus retrouvé sa position reculée. Le ressort du tronçon 22 maintient le contact entre les contacts 30 et les bornes 31. Le mécanisme comportant la came 36 est ainsi dans une positon stable dans laquelle les bornes 31 sont reliées électriquement.Simultaneously with this path of the cursor 35 on this portion of the first path, the section 22 has slid downwards in the longitudinal direction. The slider having generally traveled only half of the previous race, the section 22 also did not find its retracted position. The spring of the section 22 maintains the contact between the contacts 30 and the terminals 31. The mechanism comprising the cam 36 is thus in a stable position in which the terminals 31 are electrically connected.

Sous l'effet d'une nouvelle impulsion, l'armature 7 passe à nouveau en position de travail tout comme la manette 12 qui est alors entraînée en rotation. L'organe 4 coulisse selon la direction de coulissement vers le haut.Under the effect of a new pulse, the armature 7 goes back to the working position just as the lever 12 which is then rotated. The member 4 slides in the direction of sliding upwards.

Le curseur 35 est alors entraîné vers le haut sur un deuxième trajet. Du fait de la position de la branche 66 en alignement avec la portion oblique de la tranche 53, la branche 66 bloque le passage pour le curseur 35 vers la première position intermédiaire de sorte que celui-ci s'engage sur la portion de deuxième trajet délimité entre l'anse 51 et la tranche 53 à l'encontre de la branche 66. Lorsque le curseur 35 atteint l'extrémité de l'anse 51, il n'est plus contraint par l'îlot 40, il est alors sollicité par la branche 66 vers le mur 38 qu'il remonte jusqu'à s'arrêter légèrement à l'écart de la tranche 55. Dans cette deuxième position intermédiaire du curseur 35, l'organe 4 est situé plus haut que dans sa position reculée et que dans sa position avancée.The cursor 35 is then driven upwards on a second path. Due to the position of the branch 66 in alignment with the oblique portion of the wafer 53, the branch 66 blocks the passage for the slider 35 to the first intermediate position so that it engages the second path portion delimited between the handle 51 and the slice 53 against the branch 66. When the slider 35 reaches the end of the handle 51, it is no longer constrained by the island 40, it is then requested by the branch 66 towards the wall 38 that it rises until stopping slightly away from the slice 55. In this second intermediate position of the slider 35, the member 4 is located higher than in its retracted position and only in its advanced position.

Simultanément à ce cheminement du curseur 35 sur cette portion de deuxième trajet, le tronçon 22 a à nouveau coulissé vers le haut selon la direction de coulissement et le ressort qu'il porte s'est à nouveau contracté pour compenser le fait que les contacts 30 sont toujours contre les bornes 31.Simultaneously with this path of the cursor 35 on this portion of the second path, the section 22 has again slid upwards in the direction of sliding and the spring it carries has contracted again to compensate for the fact that the contacts 30 are still against the terminals 31.

Tant que l'impulsion se produit, le curseur 35 reste en position contre le mur 38 dans sa deuxième position intermédiaire (figure 6). Un jeu identique à celui qui existe en première position intermédiaire est également prévu pour les mêmes raisons. Dès que l'impulsion s'arrête, l'armature 7 et la manette 12 reviennent vers leur position de repos et l'organe 4 est entraîné vers sa position reculée. Le curseur 35 est alors entraîné vers le bas. Sur cette portion de son deuxième trajet, la biellette 21 et donc le curseur 35 sont sollicités en rotation dans le sens anti-horaire de sorte que le curseur 35 se déplace vers l'îlot 40 le long du mur 38 jusqu'à ce que la branche 66 vienne en butée contre le pion 56 et que le curseur 35 rencontre la deuxième branche 67. La branche 66 est alors dans sa position de repos alors que la branche 67 est sollicitée par le curseur 35 en déroulement. L'angle qu'elle forme avec la branche 66 au repos s'ouvre progressivement avec l'avancée du curseur 35. Cette rotation de la branche 67 est rendue possible par la différence d'épaisseur prévue pour le mur 38. Le curseur se déplace contre la tranche 49 de l'îlot 40 et à l'encontre de la branche 67. Lorsque le curseur 35 atteint le sommet 48 de l'îlot 40, la branche 67 est dans son état déroulé maximal. Le curseur 35 dépasse alors le sommet 48 et vient se replacer dans sa position initiale reculée avec la branche 67 qui vient le solliciter juste après le passage du sommet 48. Et le curseur 35 est situé contre la branche 67 et le mur 39 dans une position stable. L'effort de sollicitation de la branche 67 sur le curseur 35 est ici supérieur à l'effort de rappel exercé par la manette 12 et l'armature 7 sur l'organe 4.As long as the pulse occurs, the slider 35 remains in position against the wall 38 in its second intermediate position ( figure 6 ). A game identical to that which exists in the first intermediate position is also provided for the same reasons. As soon as the pulse stops, the armature 7 and the lever 12 return to their rest position and the member 4 is driven to its retracted position. The cursor 35 is then driven down. On this portion of its second path, the rod 21 and therefore the slider 35 are urged in counter-clockwise rotation so that the slider 35 moves towards the island 40 along the wall 38 until the branch 66 comes into abutment against the pin 56 and that the slider 35 meets the second branch 67. The branch 66 is then in its rest position while the branch 67 is urged by the slider 35 unwinding. The angle it forms with the branch 66 at rest gradually opens with the advance of the slider 35. This rotation of the branch 67 is made possible by the difference in thickness provided for the wall 38. The cursor moves against the edge 49 of the island 40 and against the branch 67. When the cursor 35 reaches the top 48 of the island 40, the branch 67 is in its maximum unwound state. The cursor 35 then exceeds the vertex 48 and comes back to its original retracted position with the branch 67 which comes on soliciting just after the passage of the vertex 48. And the slider 35 is located against the branch 67 and the wall 39 in a stable position. The biasing force of the branch 67 on the slider 35 is here greater than the return force exerted by the lever 12 and the armature 7 on the member 4.

Simultanément à ce cheminement du curseur 35 sur cette portion de deuxième trajet, entre la deuxième position intermédiaire et la position reculée, l'organe 4 a parcouru toute l'étendue de sa course selon la direction de coulissement. Le tronçon 22 a coulissé vers le bas. Dans un premier temps, le ressort s'est étendu et les contacts 30 se sont maintenus contre les bornes 31. Puis lorsque le haut du tronçon 22 est entré en contact avec la platine 25, le tronçon a contraint la platine 25 à coulisser avec lui vers le bas de sorte que le contact entre les contacts 30 et les bornes 31 est rompu, les bornes n'étant plus reliées électriquement. Le mécanisme comportant la came 36 est ainsi dans une positon stable dans laquelle les bornes 31 sont isolées.Simultaneously with this path of the cursor 35 on this portion of the second path, between the second intermediate position and the retracted position, the member 4 has traveled the full extent of its stroke in the direction of sliding. The section 22 has slid down. At first, the spring has extended and the contacts 30 have held against the terminals 31. Then when the top of the section 22 has come into contact with the plate 25, the section has forced the plate 25 to slide with it downwards so that the contact between the contacts 30 and the terminals 31 is broken, the terminals are no longer electrically connected. The mechanism comprising the cam 36 is thus in a stable position in which the terminals 31 are isolated.

Lors du cycle, les impulsions électriques aux bornes de la bobine 3 peuvent être remplacées par un actionnement manuel de la manette 12 par l'intermédiaire du bouton 14.During the cycle, the electrical pulses at the terminals of the coil 3 can be replaced by a manual actuation of the lever 12 by means of the button 14.

Selon une variante, les différents éléments délimitant le chemin de came présentent des formes légèrement différentes. Par exemple, la tranche 53 reste oblique jusqu'à la tranche de fond 55. Et les tranches de fond 54, 55 sont arrondies.According to one variant, the different elements delimiting the cam path have slightly different shapes. For example, wafer 53 remains oblique to bottom wafer 55. And wafers 54, 55 are rounded.

Selon une autre variante, la branche 66 ne s'étend pas au-delà du chemin de came et ne sollicite donc pas le curseur dans son déplacement à partir de la deuxième position intermédiaire et la forme de la péninsule 45, du mur latéral 38 et de l'ilot 40 sont adaptés à empêcher le retour dudit curseur 35 vers la position avancée.According to another variant, the branch 66 does not extend beyond the cam path and therefore does not urge the slider in its displacement from the second intermediate position and the shape of the peninsula 45, the lateral wall 38 and of the island 40 are adapted to prevent the return of said cursor 35 to the advanced position.

Selon un autre mode de réalisation, le mécanisme est utilisé dans un autre dispositif électrique.According to another embodiment, the mechanism is used in another electrical device.

Selon encore un autre mode de réalisation, le dispositif est utilisé dans un dispositif mécanique dans lequel les coulissements sont obtenus manuellement par une pression toujours selon la même direction et le même sens.According to yet another embodiment, the device is used in a mechanical device in which the slides are obtained manually by a pressure always in the same direction and the same direction.

On notera que dans une variante ne faisant pas partie de l'invention, la biellette 21 et le ressort 65 sont omis de sorte que le dispositif n'est plus du genre télérupteur mais du genre contacteur.Note that in a variant not part of the invention, the rod 21 and the spring 65 are omitted so that the device is not the kind of remote control but the kind of contactor.
