The lever is tiltingly mounted on the support around the tilting axis (X2) in the monostable configuration.

Description

L'invention concerne, de façon générale, les mécanismes de commande, en particulier pour les appareillages électriques.The invention relates generally to control mechanisms, in particular for electrical equipment.

Plus précisément, l'invention concerne un mécanisme de commande conçu pour adopter au moins une configuration bistable, ce mécanisme comprenant un support, un premier axe de basculement, un levier d'entraînement qui s'étend suivant un axe longitudinal et qui, en configuration bistable du mécanisme, est monté basculant sur le support, autour du premier axe, entre deux positions situées de part et d'autre d'un plan de transition fixe par rapport au support, et des organes de sollicitation pour appliquer, le long de l'axe longitudinal du levier d'entraînement, une force élastique dirigée vers le premier axe de basculement et dont l'intensité varie en sens inverse de l'angle formé entre l'axe longitudinal du levier d'entraînement et le plan de transition.More specifically, the invention relates to a control mechanism designed to adopt at least one bistable configuration, this mechanism comprising a support, a first tilting axis, a drive lever which extends along a longitudinal axis and which, in configuration bistable mechanism is mounted pivotally on the support, about the first axis, between two positions located on either side of a fixed transition plane relative to the support, and biasing members for applying, along the longitudinal axis of the drive lever, an elastic force directed towards the first tilting axis and whose intensity varies in the opposite direction to the angle formed between the longitudinal axis of the drive lever and the transition plane.

Un mécanisme de ce type est bien connu de l'homme du métier et notamment évoqué dans le brevet FR 2 864 332 .A mechanism of this type is well known to those skilled in the art and especially mentioned in the patent. FR 2 864 332 .

Comme l'indique également ce brevet antérieur, il est souvent nécessaire, notamment pour la commande d'appareillages électriques, de disposer à la fois de mécanismes de commande bistables et de mécanismes de commande monostables.As also indicated in this prior patent, it is often necessary, particularly for the control of electrical equipment, to have both bistable control mechanisms and monostable control mechanisms.

Un tel besoin peut évidemment être satisfait en fabriquant à la fois des mécanismes bistables et des mécanismes monostables, et en approvisionnant au cas par cas l'un ou l'autre de ces systèmes, selon le besoin spécifiquement exprimé.Such a need can obviously be satisfied by manufacturing both bistable mechanisms and monostable mechanisms, and by supplying on a case-by-case basis one or the other of these systems, according to the need specifically expressed.

Une autre voie, explorée dans le brevet antérieur précité, consiste à doter un mécanisme de commande unique d'un accessoire de commande mécanique susceptible d'adopter sélectivement une configuration bistable ou une configuration monostable, et d'imposer sa configuration au mécanisme de commande unique.Another way, explored in the aforementioned prior patent, consists in providing a single control mechanism with a mechanical control accessory capable of selectively adopting a bistable configuration or a monostable configuration, and imposing its configuration on the single control mechanism. .

L'invention a pour but de satisfaire le même besoin par la mise en oeuvre de moyens plus simples et plus compacts.The invention aims to satisfy the same need by the implementation of simpler and more compact means.

A cette fin, le mécanisme de l'invention, par ailleurs conforme à la définition générique qu'en donne le préambule ci-dessus, est essentiellement caractérisé en ce qu'il comprend un deuxième axe de basculement décalé à la fois de l'axe longitudinal du levier d'entraînement et du plan de transition, en ce que le levier d'entraînement présente, par rapport au support et au premier axe de basculement, une liberté de mouvement dans un plan perpendiculaire à ce premier axe de basculement, et en ce que le deuxième axe de basculement est au moins partiellement mobile par rapport au support et au levier d'entraînement, parallèlement au premier axe de basculement, et sélectivement déplacé pour lier le levier d'entraînement au support et placer le mécanisme dans une configuration monostable dans laquelle le levier d'entraînement est monté basculant sur le support autour du deuxième axe de basculement.To this end, the mechanism of the invention, which moreover conforms to the generic definition given in the preamble above, is essentially characterized in that it comprises a second axis of tilting which is offset both from the axis longitudinally of the driving lever and the transition plane, in that the drive lever has, relative to the support and the first tilting axis, freedom of movement in a plane perpendicular to this first tilting axis, and the second tilt axis is at least partially movable relative to the carrier and the drive lever, parallel to the first tilt axis, and selectively moved to link the drive lever to the carrier and place the mechanism in a monostable configuration in which the lever drive is pivotally mounted on the support around the second tilting axis.

Par exemple, le premier axe de basculement comprend au moins un élément mâle tel qu'un tourillon, porté par le levier d'entraînement ou le support, et au moins un élément femelle correspondant, tel qu'une fenêtre, prévu sur le support ou le levier d'entraînement, la liberté de mouvement du levier d'entraînement dans le plan perpendiculaire au premier axe de basculement étant obtenue par un jeu de débattement de chaque élément mâle par rapport à l'élément femelle correspondant.For example, the first tilting axis comprises at least one male element such as a trunnion, carried by the driving lever or the support, and at least one corresponding female element, such as a window, provided on the support or the drive lever, the freedom of movement of the drive lever in the plane perpendicular to the first tilting axis being obtained by a clearance of movement of each male element relative to the corresponding female element.

Dans un mode de réalisation possible, le deuxième axe de basculement comprend lui-même deux tourillons filetés insérés dans des taraudages respectifs du support, et dont chacun est susceptible d'être vissé dans le support pour s'engager dans une lumière correspondante du levier d'entraînement.In one possible embodiment, the second tilting axis itself comprises two threaded journals inserted in respective tappings of the support, and each of which is capable of being screwed into the support to engage in a corresponding light of the lever. 'training.

Les organes de sollicitation peuvent comprendre un ressort hélicoïdal précontraint en compression et maintenu le long de l'axe longitudinal du levier d'entraînement.The biasing members may comprise a helical spring prestressed in compression and held along the longitudinal axis of the driving lever.

Le mécanisme de commande de l'invention peut aussi avantageusement comprendre un troisième axe de basculement, situé dans le plan de transition à distance du premier axe de basculement, les organes de sollicitation pouvant eux-mêmes comprendre un deuxième levier monté basculant dans le support, par une première extrémité, autour du troisième axe de basculement, et dont une deuxième extrémité est en appui sur le ressort hélicoïdal.The control mechanism of the invention may also advantageously comprise a third axis of tilting, located in the transition plane at a distance from the first axis of tilting, the biasing members themselves being able to comprise a second lever mounted tilting in the support, at one end, around the third tilting axis, and a second end is supported on the coil spring.

Le deuxième levier peut alors porter une lame de contact électrique ou être constitué par une partie d'une telle lame.The second lever can then carry an electrical contact blade or be constituted by a portion of such a blade.

De façon connue en soi, le levier d'entraînement peut comporter un doigt de manoeuvre s'étendant perpendiculairement à l'axe longitudinal de ce levier d'entraînement.In a manner known per se, the drive lever may comprise an operating finger extending perpendicularly to the longitudinal axis of the drive lever.

Le mécanisme de l'invention est particulièrement bien adapté pour être appliqué à la commande d'un interrupteur électrique.The mechanism of the invention is particularly well suited to be applied to the control of an electrical switch.

Comme annoncé précédemment, l'invention concerne un mécanisme commande au moins conçu pour adopter une configuration bistable.As previously announced, the invention relates to a control mechanism at least designed to adopt a bistable configuration.

Ce mécanisme comprend, de façon connue en soi (figures 1A et 1B), un support, un axe de basculement X1, un levier d'entraînement 2, et des organes de sollicitation 31 et 32.This mechanism comprises, in a manner known per se ( Figures 1A and 1B ), a support, a tilting axis X1, a driving lever 2, and biasing members 31 and 32.

Le support, non visible sur les figures 1A et 1B, porte la référence 1 sur les figures 3 à 6.The support, not visible on Figures 1A and 1B , carries the reference 1 on the Figures 3 to 6 .

Le levier d'entraînement 2 s'étend principalement suivant un axe longitudinal L mais peut comporter un doigt de manoeuvre 21 s'étendant perpendiculairement à cet axe longitudinal L.The driving lever 2 extends mainly along a longitudinal axis L but may include an operating finger 21 extending perpendicularly to this longitudinal axis L.

En configuration bistable du mécanisme, le levier 2 est monté basculant sur le support 1, autour de l'axe X1, entre deux positions qui sont illustrées aux figures 1A et 1B et qui sont situées de part et d'autre d'un plan de transition P, fixe par rapport au support 1.In the bistable configuration of the mechanism, the lever 2 is pivotally mounted on the support 1, around the axis X1, between two positions which are illustrated in FIGS. Figures 1A and 1B and which are located on either side of a transition plane P, fixed with respect to the support 1.

Les organes de sollicitation 31 et 32, qui seront décrits plus en détail ultérieurement, ont pour fonction d'appliquer, le long de l'axe longitudinal L du levier 2, une force élastique qui est dirigée vers l'axe de basculement X1 et dont l'intensité varie en sens inverse de l'angle A que forme l'axe longitudinal L du levier 2 avec le plan de transition P.The biasing members 31 and 32, which will be described in more detail later, have the function of applying, along the longitudinal axis L of the lever 2, an elastic force which is directed towards the tilting axis X1 and whose the intensity varies inversely with the angle A formed by the longitudinal axis L of the lever 2 with the transition plane P.

En d'autres termes, la force élastique appliquée par les organes 31 et 32 croît lorsque décroît l'angle A, cette force étant donc maximale lorsque l'angle A est nul.In other words, the elastic force applied by the members 31 and 32 increases when the angle A decreases, this force being therefore maximum when the angle A is zero.

Ces caractéristiques permettent ainsi au mécanisme illustré aux figures 1A et 1B d'adopter deux états stables, et de passer par exemple du premier (figure 1A) au second (figure 1B) par l'application d'une force transitoire Ft.These characteristics thus allow the mechanism illustrated in Figures 1A and 1B to adopt two stable states, and to pass for example from the first ( Figure 1A ) to the second ( Figure 1B ) by the application of a transient force Ft.

Par rapport à ce mécanisme connu, le mécanisme de l'invention comprend (figures 2A et 2B) un deuxième axe de basculement X2, qui est décalé à la fois de l'axe longitudinal L du levier 2 et du plan de transition P.With respect to this known mechanism, the mechanism of the invention comprises Figures 2A and 2B ) a second axis X2, which is shifted both from the longitudinal axis L of the lever 2 and the transition plane P.

En outre, le levier 2 présente, par rapport au support 1 et au premier axe de basculement X1, une liberté de mouvement dans un plan perpendiculaire à cet axe X1, c'est-à-dire dans le plan des figures 2A et 2B.In addition, the lever 2 has, relative to the support 1 and the first tilting axis X1, freedom of movement in a plane perpendicular to this axis X1, that is to say in the plane of Figures 2A and 2B .

Le deuxième axe de basculement X2 est du type "embrayable". Plus précisément, cet axe 2 est conçu pour pouvoir passer d'une position inactive, dans laquelle il n'intervient pas et dans laquelle le mécanisme conserve donc sa configuration bistable telle qu'illustrée aux figures 1A et 1B, à une position active dans laquelle ce deuxième axe X2 lie le levier d'entraînement 2 au support 1 et place ainsi le mécanisme de commande de l'invention dans une configuration monostable, illustrée aux figures 2A et 2B, et dans laquelle le levier 2 est monté basculant sur le support 1 autour de cet axe X2.The second tilting axis X2 is of the "engageable" type. More specifically, this axis 2 is designed to be able to move from an inactive position, in which it does not intervene and in which the mechanism thus retains its bistable configuration as illustrated in FIGS. Figures 1A and 1B at an active position in which this second axis X2 links the driving lever 2 to the support 1 and thus places the control mechanism of the invention in a monostable configuration, illustrated in FIGS. Figures 2A and 2B , and wherein the lever 2 is pivotally mounted on the support 1 about this axis X2.

Pour ce faire, au moins un élément constitutif de l'axe X2 est mobile par rapport au support 1 et au levier d'entraînement 2 parallèlement au premier axe de basculement X1, cet élément pouvant ainsi être déplacé de sa position inactive, dans laquelle il n'est en contact qu'avec le support 1 ou le levier 2, vers sa position active dans laquelle il est en contact à la fois avec le support 1 et avec le levier 2.To do this, at least one component of the axis X2 is movable relative to the support 1 and the driving lever 2 parallel to the first axis of tilting X1, this element can thus be moved from its inactive position, in which it is in contact only with the support 1 or the lever 2, towards its active position in which it is in contact with both the support 1 and the lever 2.

Comme le montre une comparaison des figures 1A et 2A, la liaison que l'axe X2 assure, dans sa position active, entre le support 1 et le levier 2 ne modifie pas substantiellement ou pas du tout la configuration stable du mécanisme de l'invention, qui correspond sur ces figures à un état de repos.As shown by a comparison of Figures 1A and 2A , the connection that the axis X2 ensures, in its active position, between the support 1 and the lever 2 does not change substantially or not at all the stable configuration of the mechanism of the invention, which corresponds in these figures to a state of rest.

En revanche, comme le montre la figure 2B, le mécanisme de l'invention, une fois placé dans sa configuration monostable par engagement de l'axe X2, ne peut plus changer d'état que sous l'effet de l'application continue d'une force Fc, à la disparition de laquelle ce mécanisme retourne dans sa position de repos stable illustrée à la figure 2A.On the other hand, as shown in Figure 2B , the mechanism of the invention, once placed in its monostable configuration by engagement of the axis X2, can not change state unless under the effect of the continuous application of a force Fc, the disappearance of which this mechanism returns to its stable rest position illustrated in Figure 2A .

Si le support 1 est conformé en chape, le premier axe de basculement X1 est par exemple constitué d'une paire d'éléments mâles X11, tels que des tourillons coaxiaux portés par le levier 2, et d'une paire d'éléments femelles X12 correspondants, tel que des fenêtres coaxiales pratiquées dans le support 1 et dans chacune desquelles est engagé un tourillon.If the support 1 is shaped as a yoke, the first tilting axis X1 consists for example of a pair of male elements X11, such as coaxial journals carried by the lever 2, and a pair of female elements X12 corresponding, such as coaxial windows in the support 1 and in each of which is engaged a pin.

Néanmoins, l'homme du métier comprendra aisément que l'un ou chacun des tourillons pourrait être porté par le support et que l'une ou chacune des fenêtres pourrait être pratiquée dans le levier 2.Nevertheless, those skilled in the art will readily understand that one or each of the trunnions could be carried by the support and that one or each of the windows could be made in the lever 2.

En toute hypothèse, la liberté de mouvement du levier 2 dans le plan perpendiculaire au premier axe de basculement X1, c'est-à-dire dans le plan des figures 2A et 2B, est obtenue grâce à un jeu permettant le débattement de chaque tourillon X11 dans la fenêtre X12 correspondante.In any case, the freedom of movement of the lever 2 in the plane perpendicular to the first axis of tilting X1, that is to say in the plane of Figures 2A and 2B , is obtained thanks to a game allowing the travel of each X11 pin in the corresponding window X12.

Lors du passage du mécanisme de sa position stable (figure 2A) à sa position instable (figure 2B), les tourillons X11 se déplacent donc, dans les fenêtres X12 correspondantes, en parcourant un arc de cercle centré sur l'axe X2.During the passage of the mechanism from its stable position ( Figure 2A ) to its unstable position ( Figure 2B ), the X11 trunnions therefore move, in the corresponding windows X12, by traversing an arc centered on the axis X2.

Le deuxième axe X2 peut lui-même comprendre des tourillons X21 solidaires du support 1 et qui, pour placer le mécanisme dans sa configuration monostable, sont engagés dans une lumière correspondante X22 du levier 2 au moins par translation suivant la direction axiale de cet axe X2.The second axis X2 may itself comprise pins X21 integral with the support 1 and which, to place the mechanism in its monostable configuration, are engaged in a corresponding light X22 of the lever 2 at least by translation along the axial direction of this axis X2 .

L'engagement de ces tourillons X21 dans ces lumières X22 peut résulter d'une simple poussée opérant une insertion à force, comme illustré aux figures 4 et 5 sur un premier mode de réalisation de l'invention.The engagement of these X21 pins in these X22 lights can result from a simple push operating force insertion, as illustrated in FIGS. figures 4 and 5 in a first embodiment of the invention.

Dans ce cas, et à moins que les tourillons X21 puissent être extraits des lumières X22, le mécanisme de l'invention, une fois placé dans sa configuration monostable, reste indéfiniment dans cette configuration.In this case, and unless the X21 pins can be extracted from the X22 lights, the mechanism of the invention, once placed in its monostable configuration, remains indefinitely in this configuration.

La figure 6 illustre un autre mode de réalisation, dans lequel les tourillons X21 de l'axe de basculement X2 sont filetés et insérés dans des taraudages respectifs du support 1, de sorte que chaque tourillon peut à volonté être vissé dans le support 1 pour s'engager dans la lumière X22 correspondante du levier 2, ou être dévissé pour se dégager de cette lumière X22.The figure 6 illustrates another embodiment, wherein the pins X21 of the tilting axis X2 are threaded and inserted into respective threads of the support 1, so that each pin can at will be screwed into the support 1 to engage in the corresponding X22 light of the lever 2, or be unscrewed to disengage from this light X22.

En d'autres termes, le mécanisme de l'invention correspondant au mode de réalisation illustré à la figure 6 peut à tout moment être placé, au choix, dans l'une ou l'autre de ses configurations bistable et monostable.In other words, the mechanism of the invention corresponding to the embodiment illustrated in FIG. figure 6 can be placed at any time, in the choice, in one or the other of its bistable and monostable configurations.

Les organes de sollicitation précédemment évoqués comprennent par exemple un ressort hélicoïdal 31 et un deuxième levier rigide 32.The aforementioned biasing members comprise for example a helical spring 31 and a second rigid lever 32.

Le ressort hélicoïdal 31 est précontraint en compression et maintenu le long de l'axe longitudinal L du levier d'entraînement 2.The helical spring 31 is prestressed in compression and held along the longitudinal axis L of the driving lever 2.

Pour ce faire, ce levier 2 peut par exemple comprendre un corps tubulaire dans lequel est inséré le ressort 31.To do this, this lever 2 may for example comprise a tubular body in which is inserted the spring 31.

Le deuxième levier 32 présente une extrémité 321 par laquelle il monté basculant dans le support 1 autour d'un troisième axe de basculement X3, et une extrémité 322 en appui sur le ressort hélicoïdal 31.The second lever 32 has an end 321 by which it is pivotally mounted in the support 1 around a third axis of tilting X3, and an end 322 bears on the coil spring 31.

Comme le montrent les figures 1A à 2B, le troisième axe de basculement X3 est situé dans le plan de transition P, à distance de l'axe de basculement X1.As shown by Figures 1A to 2B the third tilting axis X3 is located in the transition plane P, away from the tilting axis X1.

Grâce à cet agencement, le levier 32 basculant autour de l'axe X3 comprime le ressort 31 d'autant plus que l'angle formé entre les leviers 2 et 32 est faible, c'est-à-dire d'autant plus que l'angle A est faible dans la configuration bistable du mécanisme de commande.Thanks to this arrangement, the lever 32 swinging around the axis X3 compresses the spring 31 more than the angle formed between the levers 2 and 32 is low, that is to say, especially as the angle A is small in the bistable configuration of the control mechanism.

Le mécanisme de l'invention est idéalement applicable à la commande d'un interrupteur électrique, auquel cas il est avantageux de prévoir que le deuxième levier 32 porte une lame de contact électrique 4 ou qu'il soit constitué par une partie d'une telle lame.The mechanism of the invention is ideally applicable to the control of an electrical switch, in which case it is advantageous to provide that the second lever 32 carries an electrical contact blade 4 or that it is constituted by a part of such a blade.

La lame 4 peut alors porter une pastille conductrice 41 qui peut être mise en contact électrique avec un premier plot fixe 51 (figures 1A et 2A), ou avec un deuxième plot fixe 52 (figures 1B et 2B).The blade 4 can then carry a conductive pad 41 which can be brought into electrical contact with a first fixed pad 51 ( Figures 1A and 2A ), or with a second fixed stud 52 ( Figures 1B and 2B ).
