Abstract

The control button includes a main pushbutton (14) which is associated with an auxiliary pushbutton (46) whereby the axis (19) of the mushroom head (16) is brought to bear upon it. For temporary cooperation with the catch (15), the main pushbutton has a projecting flange (52) at its top end with an edge (53) inclined at an angle to the axis of the assembly. The other edge (54) of the flange is at right angles to the axis and parallel to an edge (60) of a flange projecting from the lower end of the auxiliary pushbutton. A wing (64) of the sleeve (62) is visible through a window (65).

Description

La présente invention concerne d'une manière générale les boutons de commande sur lesquels il faut agir par enfoncement pour intervenir sur un quelconque composant sous-jacent, et, par exemple, un quelconque composant électrique.The present invention relates generally to the control buttons on which it is necessary to act by pressing to intervene on any underlying component, and, for example, any electrical component.

Ces boutons de commande, communément appelés "coup de poing" quand leur forme permet de les actionner avec la paume de la main, comportent, usuellement, un corps de guidage, par lequel ils sont adaptés à être montés sur un quelconque support, un poussoir, qui, pour action sur le composant sous-jacent, est monté mobile axialement dans le corps de guidage à la manière d'un piston, un organe de commande, en forme générale de champignon, qui, monté mobile axialement par rapport au corps de guidage, entre une position sortie d'attente et une position enfoncée de service, comporte une tête, pour action de l'usager, et un axe, pour action sur le poussoir, et, associés à cet organe de commande, des moyens élastiques de rappel, qui le sollicitent en permanence en direction de sa position sortie d'attente.These control buttons, commonly called "punch" when their shape allows them to be actuated with the palm of the hand, usually include a guide body, by which they are adapted to be mounted on any support, a pusher , which, for action on the underlying component, is mounted axially movable in the guide body in the manner of a piston, a control member, in the general shape of a mushroom, which, mounted axially movable relative to the body guide, between a standby position and a depressed service position, comprises a head, for user action, and an axis, for action on the pusher, and, associated with this control member, elastic means of reminder, which constantly urge it towards its standby position.

La présente invention vise plus particulièrement le cas où, s'agissant de boutons de commande communément dits "à accrochage de type pousser-tirer", il est en outre prévu, d'une part, des moyens d'accrochage, qui, interposés sur le trajet du poussoir, sont aptes à une retenue débrayable de celui-ci dans un sens axial au moins, en l'espèce le sens axial allant de la position enfoncée de service à la position sortie d'attente de l'organe de commande, et, d'autre part, intervenant entre le poussoir et l'axe de l'organe de commande, des moyens d'attelage à jeu, qui permettent d'exercer une traction sur le poussoir par l'intermédiaire de l'organe de commande, et, par là, permettent de ramener cet organe de commande en position sortie d'attente.The present invention relates more particularly to the case where, in the case of control buttons commonly known as "push-type latching", there is further provided, on the one hand, latching means, which, interposed on the path of the pusher, are capable of disengageable retention of the latter in at least one axial direction, in this case the axial direction going from the depressed service position to the standby out position of the control member, and, on the other hand, intervening between the pusher and the axis of the control member, coupling means with clearance, which make it possible to exert traction on the pusher by means of the control member , and thereby make it possible to return this control member to the standby exit position.

Ces boutons de commande sont par exemple utilisés pour assurer un arrêt qu'il convient de faire perdurer.These control buttons are for example used to ensure a stop that should be maintained.

Pour ce faire, il suffit d'exercer une action d'enfoncement sur l'organe de commande.To do this, it suffices to exert a driving action on the control member.

Du fait de cette action d'enfoncement, le poussoir est lui-même déplacé en direction du composant à commander, ce qui lui permet d'agir sur celui-ci, en le faisant par exemple basculer d'un premier état à un autre.Due to this pushing action, the pusher is itself moved in the direction of the component to be controlled, which allows it to act on it, for example by switching it from one first state to another.

Conjointement, le poussoir vient se prendre sous les moyens d'accrochage, et, dès lors retenu par ceux-ci, il retient lui-même en position enfoncée de service l'organe de commande tout en maintenant dans son nouvel état le composant sous-jacent.At the same time, the pusher is caught under the hooking means, and, therefore retained by the latter, it retains the control member itself in the depressed service position while maintaining the sub-component in its new state. jacent.

Pour le retour de ce composant à son état initial, c'est-à-dire pour un basculement inverse de ce composant d'un de ses états à l'autre, il faut exercer sur l'organe de commande une traction suffisante pour que, entraîné par cet organe de commande, le poussoir puisse à nouveau franchir élastiquement les moyens d'accrochage, dans le sens axial opposé au précédent, et ainsi libérer ce composant.For the return of this component to its initial state, that is to say for a reverse tilting of this component from one of its states to the other, it is necessary to exert on the control member a sufficient traction so that , driven by this control member, the pusher can again pass elastically the hooking means, in the axial direction opposite to the previous one, and thus release this component.

Mais, en pratique, eu égard aux courses disponibles, l'action du poussoir sur le composant sous-jacent intervient avant qu'il franchisse les moyens d'accrochage.However, in practice, having regard to the available strokes, the action of the pusher on the underlying component occurs before it crosses the attachment means.

Autrement dit, le basculement d'un état à un autre de ce composant intervient avant l'accrochage du poussoir, et, donc, de l'organe de commande.In other words, the switching from one state to another of this component occurs before the pusher, and therefore the latching device, is hooked.

Par suite, si cet organe de commande est inopportunément relâché avant cet accrochage, le composant sous-jacent revient inévitablement à son état initial, alors même qu'il a été temporairement basculé dans un autre état dans l'intervalle.As a result, if this control member is inappropriately released before this attachment, the underlying component inevitably returns to its initial state, even though it has been temporarily switched to another state in the meantime.

Autrement dit, le composant sous-jacent est, dans ce cas, intempestivement l'objet de deux changements d'état successifs.In other words, the underlying component is, in this case, inadvertently the object of two successive changes of state.

La présente invention a d'une manière générale pour objet une disposition permettant d'éviter cet inconvénient.The present invention generally relates to a provision making it possible to avoid this drawback.

De manière plus précise, elle a pour objet un bouton de commande du genre comportant un corps de guidage, par lequel il est adapté à être monté sur un quelconque support, un poussoir, qui, pour action sur un quelconque composant sous-jacent, est monté mobile axialement dans ce corps de guidage à la manière d'un piston, des moyens d'accrochage, qui, interposés sur le trajet du poussoir, pour une retenue débrayable de celui-ci dans un sens axial au moins, sont élastiquement effaçables, un organe de commande, qui, monté mobile axialement par rapport au corps de guidage, entre une position sortie d'attente et une position enfoncée de service, comporte une tête, pour action de l'usager, et un axe, pour action sur le poussoir, des moyens élastiques de rappel, qui, associés à cet organe de commande, sollicitent en permanence celui-ci en direction de sa position sortie d'attente, et, intervenant entre le poussoir et l'axe de l'organe de commande, des moyens d'attelage à jeu, qui permettent d'exercer une traction sur le poussoir par l'intermédiaire de l'organe de commande, ce bouton de commande étant d'une manière générale caractérisé en ce que, en association avec le poussoir, dit ci-après par simple commodité poussoir principal, il comporte, en outre, entre ce poussoir principal et l'axe de l'organe de commande, dans l'alignement du poussoir principal, un poussoir auxiliaire, par l'intermédiaire duquel ledit axe de l'organe de commande peut intervenir sur le poussoir principal, et qui est lui aussi apte à coopérer en retenue débrayable avec les moyens d'accrochage, avec, intervenant entre le poussoir principal et le poussoir auxiliaire, des moyens élastiques d'écartement, qui, par eux-mêmes, constituent les moyens élastiques de rappel associés à l'organe de commande.More specifically, it relates to a control button of the kind comprising a guide body, by which it is adapted to be mounted on any support, a pusher, which, for action on any underlying component, is mounted axially movable in this guide body in the manner of a piston, hooking means which, interposed on the path of the pusher, for retention disengageable therefrom in at least one axial direction, are elastically erasable, a control member which, mounted axially movable relative to the guide body, between a standby position and a depressed service position, comprises a head , for user action, and an axis, for action on the pusher, elastic return means, which, associated with this control member, permanently urge the latter in the direction of its standby position, and , intervening between the pusher and the axis of the control member, coupling means with clearance, which make it possible to exert traction on the pusher via the control member, this control button being generally characterized in that, in association with the pusher, said hereinafter by simple convenience main pusher, it further comprises, between this main pusher and the axis of the control member, in the alignment of the main pusher, an auxilia pusher ire, by means of which said axis of the control member can intervene on the main pusher, and which is also capable of cooperating in disengageable retainer with the hooking means, with, intervening between the main pusher and the pusher auxiliary, elastic spacing means, which, by themselves, constitute the elastic return means associated with the control member.

Grâce à une telle disposition, il est avantageusement possible de disposer, pour le poussoir principal, d'une course axiale suffisante pour que son action sur le composant sous-jacent, et, donc, le basculement de celui-ci d'un état à un autre, n'intervienne qu'après le franchissement des moyens d'accrochage.Thanks to such an arrangement, it is advantageously possible to have, for the main pusher, an axial stroke sufficient for its action on the underlying component, and, therefore, the tilting thereof from a state to another, only intervenes after crossing the attachment means.

Autrement dit, le composant sous-jacent n'est avantageusement l'objet d'aucun changement d'état avant cet accrochage, et un relâchement inopiné de l'organe de commande dans l'intervalle reste ainsi sans effet.In other words, the underlying component is advantageously not subject to any change of state before this attachment, and an unexpected relaxation of the control member in the meantime thus remains without effect.

Conjointement, après le franchissement des moyens d'accrochage, le poussoir principal dispose, par lui-même, en s'écartant du poussoir auxiliaire, de toute la course axiale nécessaire pour agir en toute certitude, et de manière franche, sur le composant sous-jacent, sans risquer de libérer celui-ci de manière intempestive avant qu'une traction ait été dûment exercée à cet effet sur l'organe de commande.At the same time, after the hooking means have been cleared, the main pusher has, by itself, away from the auxiliary pusher, all the axial travel necessary to act with certainty, and in a frank manner, on the underlying component, without the risk of releasing it inadvertently before traction has been duly exerted on the control member for this purpose.

Préférentiellement, suivant une disposition complémentaire de l'invention, il est associé, à l'organe de commande, un voyant de position, qui est monté mobile entre deux positions, à savoir, une position escamotée, lorsque l'organe de commande est en position sortie d'attente, et une position déployée, lorsque cet organe de commande est en position enfoncée de service, et dont une portion, au moins, cachée en position escamotée, devient apparente en position déployée.Preferably, according to a complementary arrangement of the invention, there is associated, with the control member, a position indicator, which is mounted movable between two positions, namely, a retracted position, when the control member is in standby position, and a deployed position, when this control member is in the depressed service position, and at least a portion of which, hidden in the retracted position, becomes apparent in the deployed position.

Ainsi, la position sortie, d'attente, ou enfoncée, de service, de l'organe de commande, est clairement signalée, alors même que la course de cet organe de commande de l'une à l'autre de ces positions est en général trop faible pour que son seul examen permette d'en déterminer sans ambiguïté la position.Thus, the extended, waiting, or depressed, service position of the control member is clearly indicated, even though the travel of this control member from one of these positions to the other is in general too weak for its sole examination to unambiguously determine its position.

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

Tel qu'illustré schématiquement sur les figures 1 et 2, il s'agit, globalement, d'agir sur un quelconque composant 10, et, par exemple, sur un quelconque composant électrique, tel qu'un interrupteur, pour en provoquer un changement d'état, c'est-à-dire le basculement d'un état à un autre.As illustrated diagrammatically in FIGS. 1 and 2, it is a question, overall, of acting on any component 10, and, for example, on any electrical component, such as a switch, to cause a change thereof. state, i.e. switching from one state to another.

Pour action sur ce composant 10 il est mis en oeuvre un bouton de commande 11 comportant, globalement, un corps de guidage 12, par lequel, tel que schématisé en traits interrompus sur la figure 4, il est adapté à être monté sur un quelconque support 13, un poussoir 14, qui, pour action sur le composant 10 sous-jacent, est monté mobile axialement, à la manière d'un piston, dans le corps de guidage 12, des moyens d'accrochage 15, qui, interposés sur le trajet du poussoir 14, pour une retenue débrayable de celui-ci dans un sens axial au moins, sont élastiquement effaçables, un organe de commande 16, en forme générale de champignon, qui, monté mobile axialement par rapport au corps de guidage 12, entre une position sortie d'attente, représentée sur les figures 1 et 4, et une position enfoncée de service, représentée sur les figures 2 et 5C, comporte une tête 18, pour action de l'usager, et un axe 19, pour action sur le poussoir 14, des moyens élastiques de rappel, qui, suivant des dispositions décrites plus en détail ultérieurement, sollicitent en permanence l'organe de commande 16 en direction de sa position sortie d'attente, et, intervenant entre le poussoir 14 et l'axe 19 de l'organe de commande 16, suivant des dispositions également décrites plus en détail ultérieurement, des moyens d'attelage à jeu 20, qui, dans le sens axial opposé au précédent, permettent d'exercer une traction sur le poussoir 14 par l'intermédiaire de l'organe de commande 16.For action on this component 10, a control button 11 is implemented comprising, overall, a guide body 12, by which, as shown diagrammatically in broken lines in FIG. 4, it is adapted to be mounted on any support. 13, a pusher 14, which, for action on the underlying component 10, is mounted axially movable, in the manner of a piston, in the guide body 12, hooking means 15, which, interposed on the path of the pusher 14, for a disengageable retention of the latter in at least one axial direction, are elastically erasable, a control member 16, in the general shape of a mushroom, which, mounted axially movable relative to the guide body 12, between a standby exit position, shown in Figures 1 and 4, and a depressed service position, shown in Figures 2 and 5C, has a head 18, for user action, and a pin 19, for action on the pusher 14, elastic return means, which i, according to arrangements described in more detail later, permanently urge the control member 16 towards its standby position, and acting between the pusher 14 and the axis 19 of the control member 16, according to provisions also described in more detail later, play coupling means 20, which, in the axial direction opposite to the previous, allow to exert traction on the pusher 14 via the control member 16 .

Par exemple, et tel que schématisé sur la figure 4, le support 13 est une simple plaque dans un évidement 17 de laquelle le corps de guidage 12 est engagé par une portion filetée 21.For example, and as shown diagrammatically in FIG. 4, the support 13 is a simple plate in a recess 17 from which the guide body 12 is engaged by a portion threaded 21.

En pratique, l'évidement 17 du support 13 et la portion filetée 21 du corps de guidage 12 ont un contour circulaire.In practice, the recess 17 of the support 13 and the threaded portion 21 of the guide body 12 have a circular contour.

D'un côté, le corps de guidage 12 prend appui contre le support 13 par un épaulement 23, et, de l'autre côté, un écrou 33 est vissé sur sa portion filetée 21, pour son blocage en position sur ce support 13.On one side, the guide body 12 bears against the support 13 by a shoulder 23, and, on the other side, a nut 33 is screwed onto its threaded portion 21, for its locking in position on this support 13.

Dans les formes de réalisation représentées, la tête 18 de l'organe de commande 16 a en plan un contour circulaire, et elle comporte périphériquement une jupe 24 par laquelle elle coopère en blocage en rotation et en guidage avec un manchon 25 fixe.In the embodiments shown, the head 18 of the control member 16 has a circular outline in plan, and it peripherally comprises a skirt 24 by which it cooperates in rotation lock and in guidance with a fixed sleeve 25.

En pratique, ce manchon 25 appartient d'un seul tenant au corps de guidage 12.In practice, this sleeve 25 belongs integrally to the guide body 12.

Il intervient à la périphérie d'une semelle 26, de contour circulaire, qui, constituant un épanouissement radial à la partie supérieure de la portion filetée 21, forme par sa surface inférieure l'épaulement 23.It intervenes at the periphery of a sole 26, of circular outline, which, constituting a radial development at the upper part of the threaded portion 21, forms by its lower surface the shoulder 23.

Dans les formes de réalisation représentées, les moyens d'accrochage 15 sont constitués par un ressort, qui s'étend annulairement autour de l'axe de l'ensemble, et qui est calé axialement par rapport au corps de guidage 12.In the embodiments shown, the hooking means 15 are constituted by a spring, which extends annularly around the axis of the assembly, and which is wedged axially relative to the guide body 12.

Il s'agit en pratique d'un ressort de traction, du type ressort à boudin, dont la section transversale est circulaire, et qui, par ses extrémités, est refermé en boucle sur lui-même.In practice, it is a tension spring, of the coil spring type, the cross section of which is circular, and which, at its ends, is closed in a loop on itself.

Pour le maintien axial du ressort constituant ainsi les moyens d'accrochage 15, il est prévu une bague 27 fixe, c'est-à-dire une bague qui, coaxiale du corps de guidage 12, en étant disposée dans l'alignement de la portion filetée 21 de celui-ci, est calée axialement et circulairement par rapport à ce corps de guidage 12.For the axial retention of the spring thus constituting the attachment means 15, there is provided a stationary ring 27, that is to say a ring which, coaxial with the guide body 12, being arranged in alignment with the threaded portion 21 thereof, is wedged axially and circularly relative to this guide body 12.

En pratique, et pour des raisons qui apparaîtront ci-après, cette bague 27 comporte successivement deux tronçons de diamètres différents, à savoir, à sa partie inférieure, un tronçon de plus grand diamètre 27A, par la tranche 28 duquel elle est appliquée à la semelle 26 du corps de guidage 12, et, à sa partie supérieure, un tronçon de plus petit diamètre 27B, qui s'étend librement autour de l'axe 19 de l'organe de commande 16, à distance de celui-ci.In practice, and for reasons which will appear below, this ring 27 successively comprises two sections of different diameters, namely, at its lower part, a section of larger diameter 27A, by the edge 28 of which it is applied to the sole 26 of the guide body 12, and, at its upper part, a section of smaller diameter 27B, which extends freely around the axis 19 of the control member 16, at a distance from the latter.

Une collerette 29, en prise à vissage avec une douille 30 venue d'un seul tenant de la semelle 26 du corps de guidage 12, maintient la bague 27 en appui contre cette semelle 26, en portant pour ce faire sur un épaulement 31 prévu à cet effet en saillie sur le tronçon de plus grand diamètre 27A de cette bague 27.A flange 29, in screw connection with a sleeve 30 coming in one piece from the sole 26 of the guide body 12, keeps the ring 27 in abutment against this sole 26, by carrying for this purpose on a shoulder 31 provided at this protruding effect on the section of larger diameter 27A of this ring 27.

Pour son blocage en rotation sur le corps de guidage 12, la bague 27 présente, circulairement, de place en place, en saillie sur la tranche 28 de son tronçon de plus grand diamètre 27A, des ergots 32 par lesquels elle est en prise avec des évidements, non visibles sur les figures, prévus en correspondance en creux à cet effet sur la semelle 26 du corps de guidage 12.For its rotation lock on the guide body 12, the ring 27 has, circularly, from place to place, projecting from the edge 28 of its section of larger diameter 27A, lugs 32 by which it is engaged with recesses, not visible in the figures, provided in hollow correspondence for this purpose on the sole 26 of the guide body 12.

Par son tronçon de plus grand diamètre 27A, la bague 27 forme par ailleurs intérieurement à sa base, en coopération avec la semelle 26 du corps de guidage 12, un logement 34 à la faveur duquel s'étend le ressort constituant les moyens d'accrochage 15.By its section of larger diameter 27A, the ring 27 also forms internally at its base, in cooperation with the sole 26 of the guide body 12, a housing 34 through which extends the spring constituting the attachment means 15.

Ce logement 34 a, radialement, un développement suffisant pour permettre une certaine extension radiale de ces moyens d'accrochage 15.This housing 34 has, radially, a development sufficient to allow a certain radial extension of these attachment means 15.

Le poussoir 14, dit ci-après, pour des raisons qui apparaîtront ultérieurement, poussoir principal, comporte, d'un seul tenant, de manière concentrique, et suivant un contour circulaire, dans les formes de réalisation représentées, d'une part, une collerette périphérique 35, par laquelle il est monté à coulissement dans le corps de guidage 12, et, plus précisément, dans la portion filetée 21 de celui-ci, et, d'autre part, un fût central 36, qui, de hauteur supérieure à celle de la collerette périphérique 35, est relié à sa base à celle-ci, et sur lequel interviennent les moyens d'attelage à jeu 20 prévus entre l'ensemble et l'axe 19 de l'organe de commande 16, avec, annulairement, entre cette collerette périphérique 35 et ce fût central 36, une saignée borgne 37.The pusher 14, said below, for reasons which will appear later, the main pusher, comprises, in one piece, concentrically, and along a circular contour, in the embodiments shown, on the one hand, a peripheral flange 35, by which it is slidably mounted in the guide body 12, and, more precisely, in the threaded portion 21 thereof, and, on the other hand, a central barrel 36, which, of greater height to that of the peripheral flange 35, is connected at its base thereto, and on which the play coupling means 20 provided between the assembly and the axis 19 of the control member 16 intervene, with, annularly, between this peripheral flange 35 and this central shaft 36, a blind groove 37.

Dans les formes de réalisation représentées, la collerette périphérique 35 du poussoir principal 14 porte, extérieurement, à la faveur d'une gorge annulaire 38, un joint d'étanchéité 39, et il s'agit en pratique d'un joint à lèvre.In the embodiments shown, the peripheral flange 35 of the main pusher 14 carries, externally, by means of an annular groove 38, a seal 39, and it is in practice a lip seal.

Dans les formes de réalisation représentées, les moyens d'attelage à jeu 20 intervenant entre le poussoir principal 14 et l'axe 19 de l'organe de commande 16 comportent, d'une part, sur l'un quelconque des constituants que forment ce poussoir principal 14 et cet axe 19, au moins une patte élastiquement déformable 40, qui, allongée globalement parallèlement à l'axe de l'ensemble, comporte, transversalement, en saillie, un bourrelet de crochetage 41, et, d'autre part, sur l'autre de ces constituants, un évidement 42 à la faveur duquel peut se débattre ce bourrelet de crochetage 41.In the embodiments shown, the clearance coupling means 20 acting between the main pusher 14 and the axis 19 of the control member 16 comprise, on the one hand, on any one of the constituents that form this main pusher 14 and this axis 19, at least one elastically deformable tab 40, which, elongated generally parallel to the axis of the assembly, comprises, transversely, projecting, a hooking bead 41, and, on the other hand, on the other of these constituents, a recess 42 in favor of which this catching bead 41 can be struggled.

En pratique, deux pattes élastiquement déformables 40, au moins, sont prévues, en étant régulièrement réparties circulairement autour de l'axe de l'ensemble, et elles sont formées par l'extrémité libre, dûment fragmentée à cet effet par des fentes, du fût central 36 du poussoir principal 14.In practice, at least two elastically deformable tabs 40 are provided, being regularly distributed circularly around the axis of the assembly, and they are formed by the free end, duly fragmented for this purpose by slots, of the central barrel 36 of the main pusher 14.

Conjointement, les évidements 42 correspondants appartiennent à l'axe 19 de l'organe de commande 16.Together, the corresponding recesses 42 belong to the axis 19 of the control member 16.

A cet effet, cet axe 19 est creusé intérieurement d'un alésage 44 dans lequel pénètre l'extrémité libre du fût central 36 du poussoir principal 14 formant les pattes élastiquement déformables 40.To this end, this axis 19 is hollowed out internally with a bore 44 into which the free end of the central barrel 36 of the main pusher 14 penetrates, forming the elastically deformable tabs 40.

Dans la forme de réalisation plus particulièrement représentée sur les figures 1 à 5, l'alésage 44 de l'axe 19 de l'organe de commande 16 est fermé à la surface de la tête 18 de cet organe de commande 16, et les évidements 42 sont constitués par des fenêtres ajourant localement cet axe 19.In the embodiment more particularly shown in Figures 1 to 5, the bore 44 of the axis 19 of the control member 16 is closed at the surface of the head 18 of this control member 16, and the recesses 42 are formed by windows locally perforating this axis 19.

Suivant l'invention, le bouton de commande 11 comporte, en association avec le poussoir principal 14, entre le poussoir principal 14 et l'axe 19 de l'organe de commande 16, dans l'alignement du poussoir principal 14, un poussoir auxiliaire 46, par l'intermédiaire duquel l'axe 19 de l'organe de commande 16 peut intervenir sur le poussoir principal 14, et qui est lui aussi apte à coopérer en retenue débrayable avec les moyens d'accrochage 15, avec, intervenant entre le poussoir principal 14 et le poussoir auxiliaire 46, des moyens élastiques d'écartement 47 qui, par eux-mêmes, constituent les moyens élastiques de rappel associés à l'organe de commande 16.According to the invention, the control button 11 comprises, in association with the main pusher 14, between the main pusher 14 and the axis 19 of the control member 16, in alignment with the main pusher 14, an auxiliary pusher 46, by means of which the axis 19 of the control member 16 can act on the main pusher 14, and which is also capable of cooperating in disengageable retention with the means attachment 15, with, intervening between the main pusher 14 and the auxiliary pusher 46, elastic spacer means 47 which, by themselves, constitute the elastic return means associated with the control member 16.

En pratique, les moyens élastiques d'écartement 47 sont constitués par un ressort de compression, du type ressort à boudin, qui, disposé annulairement dans la saignée borgne 37 du poussoir principal 14, porte, d'une part, sur le fond 48 de cette saignée borgne 37, et, d'autre part, sur un épaulement 49 que présente intérieurement à cet effet le poussoir auxiliaire 46.In practice, the elastic spacing means 47 are constituted by a compression spring, of the coil spring type, which, arranged annularly in the blind groove 37 of the main pusher 14, bears, on the one hand, on the bottom 48 of this blind groove 37, and, on the other hand, on a shoulder 49 which the auxiliary pusher 46 internally presents for this purpose.

En pratique, également, le poussoir auxiliaire 46 est une pièce annulaire qui s'étend autour de l'axe 19 de l'organe de commande 16, entre celui-ci et le tronçon de plus petit diamètre 27B de la bague 27, et il est monté coulissant dans cette dernière.In practice, too, the auxiliary pusher 46 is an annular piece which extends around the axis 19 of the control member 16, between the latter and the section of smaller diameter 27B of the ring 27, and it is slidably mounted in the latter.

A distance de l'épaulement 49, le poussoir auxiliaire 46 présente, intérieurement, un deuxième épaulement 50, qui est orienté en sens opposé, et par lequel, sous la sollicitation des moyens élastiques d'écartement 47, il est en appui contre un épaulement 51 prévu extérieurement à cet effet sur l'axe 19 de l'organe de commande 16.At a distance from the shoulder 49, the auxiliary pusher 46 has, internally, a second shoulder 50, which is oriented in the opposite direction, and by which, under the stress of the elastic spacing means 47, it bears against a shoulder 51 provided externally for this purpose on the axis 19 of the control member 16.

Globalement, le poussoir auxiliaire 46 est axialement dans le prolongement de la collerette périphérique 35 du poussoir principal 14.Overall, the auxiliary pusher 46 is axially in the extension of the peripheral flange 35 of the main pusher 14.

Pour coopération en retenue temporaire avec les moyens d'accrochage 15, le poussoir principal 14 comporte, annulairement, en saillie vers l'extérieur, sur sa collerette périphérique 35, à son extrémité proche du poussoir auxiliaire 46, un bourrelet 52, dont celui, 53, au moins des flancs qui est tourné du côté opposé au poussoir auxiliaire 46 s'étend en oblique par rapport à l'axe de l'ensemble, en se rapprochant de cet axe au fur et à mesure qu'il s'éloigne du poussoir auxiliaire 46.For cooperation in temporary retention with the hooking means 15, the main pusher 14 comprises, annularly, projecting outwards, on its peripheral flange 35, at its end close to the auxiliary pusher 46, a bead 52, including that, 53, at least of the sides which is turned on the side opposite to the auxiliary pusher 46 extends obliquely with respect to the axis of the assembly, approaching this axis as it moves away from the auxiliary pusher 46.

En pratique, l'autre, 54, des flancs de ce bourrelet 52 s'étend sensiblement perpendiculairement à l'axe de l'ensemble, en formant la tranche d'extrémité correspondante du poussoir principal 14, et, donc, plus précisément, de la collerette périphérique 35 de celui-ci.In practice, the other, 54, of the sides of this bead 52 extends substantially perpendicular to the axis of the assembly, forming the corresponding end edge the main pusher 14, and therefore, more precisely, the peripheral flange 35 thereof.

Pour faciliter le moulage des pattes élastiquement déformables 40, l'extrémité de la collerette périphérique 35 du poussoir principal 14 présentant le bourrelet 52 est, dans les formes de réalisation représentées, échancrée par des encoches 56, en correspondance avec ces pattes élastiquement déformables 40, au-dessus de la gorge annulaire 38 servant de logement au joint d'étanchéité 39.To facilitate the molding of the elastically deformable tabs 40, the end of the peripheral flange 35 of the main plunger 14 having the bead 52 is, in the embodiments shown, notched by notches 56, in correspondence with these elastically deformable tabs 40, above the annular groove 38 serving as a housing for the seal 39.

Pour coopération en retenue temporaire avec les moyens d'accrochage 15, le poussoir auxiliaire 46 comporte, annulairement, en saillie vers l'extérieur, à son extrémité proche du poussoir principal 14, un bourrelet 58, dont celui, 59, au moins, des flancs qui est tourné du côté opposé au poussoir principal 14 s'étend en oblique par rapport à l'axe de l'ensemble, en se rapprochant de cet axe au fur et à mesure qu'il s'éloigne du poussoir principal 14.For cooperation in temporary retention with the hooking means 15, the auxiliary pusher 46 comprises, annularly, projecting outwards, at its end close to the main pusher 14, a bead 58, including that, 59, at least, of the sidewalls which is turned on the side opposite to the main pusher 14 extends obliquely to the axis of the assembly, approaching this axis as it moves away from the main pusher 14.

En pratique, l'autre, 60, des flancs de ce bourrelet 58 s'étend sensiblement perpendiculairement à l'axe de l'ensemble, en formant la tranche d'extrémité correspondante du poussoir auxiliaire 46.In practice, the other, 60, of the sides of this bead 58 extends substantially perpendicular to the axis of the assembly, forming the corresponding end edge of the auxiliary pusher 46.

Dans les formes de réalisation représentées, il est associé, à l'organe de commande 16, un voyant de position 62, qui est monté mobile entre deux positions, à savoir une position escamotée, figures 1 et 4, lorsque l'organe de commande 16 est en position sortie d'attente, et une position déployée, figures 2 et 5C, lorsque cet organe de commande 16 est en position enfoncée de service, et dont une portion au moins, détaillée ci-après, est cachée en position escamotée et devient apparente en position déployée.In the embodiments shown, there is associated, with the control member 16, a position indicator 62, which is mounted movable between two positions, namely a retracted position, FIGS. 1 and 4, when the control member 16 is in the standby position, and a deployed position, FIGS. 2 and 5C, when this control member 16 is in the depressed service position, and at least a portion of which, detailed below, is hidden in the retracted position and becomes apparent in the deployed position.

En pratique, dans les formes de réalisation représentées, ce voyant de position 62 comporte, d'une part, un moyeu 63, par lequel il entoure à rotation l'axe 19 de l'organe de commande 16, au-dessus du poussoir auxiliaire 46, et, d'autre part, un épanouissement 64, qui, en forme d'aile, s'étend, suivant un secteur circulaire, sous la tête 18 de l'organe de commande 16, et, conjointement, la tête 18 de l'organe de commande 16 comporte, localement, sur le trajet de cet épanouissement 64, une fenêtre 65.In practice, in the embodiments shown, this position indicator 62 comprises, on the one hand, a hub 63, by which it rotatably surrounds the axis 19 of the control member 16, above the auxiliary pusher 46, and, on the other hand, an opening 64, which, in the shape of a wing, extends, in a circular sector, under the head 18 of the control member 16, and, jointly, the head 18 of the control member 16 comprises, locally, on the path of this opening 64, a window 65.

En pratique, également, cette fenêtre 65 est fermée par un hublot transparent 66 dans les formes de réalisation représentées.In practice, also, this window 65 is closed by a transparent window 66 in the embodiments shown.

Pour la commande en rotation du voyant de position 62, des moyens de came 67 sont prévus entre lui et la bague 27 fixe.For the rotary control of the position indicator 62, cam means 67 are provided between it and the fixed ring 27.

En pratique, ces moyens de came 67 comportent, sur la bague 27, au moins une rainure 67A hélicoïdale, et, en correspondance, sur le voyant de position 62, au moins un ergot 67B en prise avec cette rainure 67A hélicoïdale.In practice, these cam means 67 comprise, on the ring 27, at least one helical groove 67A, and, in correspondence, on the position indicator 62, at least one lug 67B engaged with this helical groove 67A.

Par exemple, et tel que représenté, deux rainures 67A, et donc deux ergots 67B, sont prévus.For example, and as shown, two grooves 67A, and therefore two pins 67B, are provided.

La bague 27 ainsi associée au voyant de position 62 pour sa commande en rotation est la même que celle associée au poussoir auxiliaire 46 pour le guidage de celui-ci.The ring 27 thus associated with the position indicator 62 for its rotation control is the same as that associated with the auxiliary pusher 46 for guiding the latter.

Les rainures 67A affectent son tronçon de plus petit diamètre 27B.The grooves 67A affect its smaller diameter section 27B.

Par exemple, et tel que représenté en traits continus sur la figure 3, elles affectent à pleine épaisseur ce tronçon de plus petit diamètre 27B sur la totalité de leur longueur.For example, and as shown in solid lines in Figure 3, they affect at full thickness this section of smaller diameter 27B over their entire length.

Cependant, et tel que schématisé en traits interrompus sur cette figure 3, un pont 68, de moindre épaisseur, peut être prévu entre leurs deux lèvres à leur débouché, pour éviter une ouverture en cône du tronçon de plus petit diamètre 27B de la bague 27.However, and as shown schematically in broken lines in this FIG. 3, a bridge 68, of lesser thickness, can be provided between their two lips at their outlet, to avoid an opening in cone of the section of smaller diameter 27B of the ring 27 .

Dans la forme de réalisation représentée en traits continus sur la figure 3, le voyant de position 62 ne comporte qu'un épanouissement 64, et, ainsi qu'il est visible sur la figure 2, celui-ci peut comporter une quelconque mention 70.In the embodiment shown in solid lines in FIG. 3, the position indicator 62 has only one opening 64, and, as can be seen in FIG. 2, this may include any mention 70.

Mais, suivant la variante schématisée en traits interrompus sur la figure 3, deux épanouissements 64, identiques l'un à l'autre, peuvent être prévus, pour permettre indifféremment le montage du voyant de position 62 dans un sens ou dans l'autre par rapport à l'axe 19 de l'organe de commande 16.However, according to the variant shown diagrammatically in broken lines in FIG. 3, two openings 64, identical to each other, can be provided, to allow indifferently the mounting of the position indicator 62 in one direction or the other by relative to the axis 19 of the control member 16.

Préférentiellement, ce voyant de position 62 est en couleur.Preferably, this position indicator 62 is in color.

Pour la position sortie d'attente représentée sur les figures 1 et 4, le poussoir principal 14 est crocheté par son bourrelet 52 sur le ressort constituant les moyens d'accrochage 15, et ainsi retenu par ce ressort, il est en quelque sorte en position haute dans le corps de guidage 12, son extrémité libre 71 étant largement en retrait par rapport à celle 72 de la portion filetée 21 de ce dernier.For the standby position shown in FIGS. 1 and 4, the main pusher 14 is hooked by its bead 52 on the spring constituting the hooking means 15, and thus retained by this spring, it is in a way in position high in the guide body 12, its free end 71 being largely set back relative to that 72 of the threaded portion 21 of the latter.

Ainsi escamoté dans le corps de guidage 12, le poussoir principal 14 est à distance du composant 10, qui, par exemple, est dans un quelconque premier état.Thus retracted into the guide body 12, the main pusher 14 is at a distance from the component 10, which, for example, is in any first state.

Conjointement, les ergots 67B du voyant de position 62 sont en prise avec les rainures 67A de la bague 27, au voisinage du débouché de celles-ci, et, par construction, les dispositions sont telles que l'épanouissement 64 de ce voyant de position 62 est alors angulairement à distance de la fenêtre 65 de la tête 18 de l'organe de commande 16.Conjointly, the pins 67B of the position indicator 62 are in engagement with the grooves 67A of the ring 27, in the vicinity of the outlet of the latter, and, by construction, the arrangements are such that the opening 64 of this position indicator 62 is then angularly at a distance from the window 65 of the head 18 of the control member 16.

Conjointement, également, le poussoir auxiliaire 46, refoulé par les moyens élastiques d'écartement 47, s'étend à distance du poussoir principal 14, sa retenue étant assurée, à travers l'organe de commande 16, par les moyens d'attelage à jeu 20 intervenant entre l'axe 19 de cet organe de commande 16 et le poussoir principal 14.Together, also, the auxiliary pusher 46, driven back by the elastic spacing means 47, extends at a distance from the main pusher 14, its retention being ensured, through the control member 16, by the coupling means to clearance 20 intervening between the axis 19 of this control member 16 and the main pusher 14.

Si, suivant la flèche F1 des figures 1, 4, 5A et 5B, une action d'enfoncement est exercée axialement sur l'organe de commande 16, cet organe de commande 16 abandonne sa position sortie d'attente, et, ainsi sollicité en direction de sa position enfoncée de service, il refoule avec lui le poussoir auxiliaire 46.If, according to the arrow F1 in FIGS. 1, 4, 5A and 5B, a driving action is exerted axially on the control member 16, this control member 16 abandons its standby position, and, thus requested in direction of its depressed service position, it drives the auxiliary plunger 46 with it.

Après absorption de la distance le séparant initialement du poussoir principal 14, le poussoir auxiliaire 46 vient porter sur celui-ci.After absorption of the distance initially separating it from the main pusher 14, the auxiliary pusher 46 comes to bear on the latter.

Le mouvement d'enfoncement de l'organe de commande 16 étant poursuivi, le poussoir auxiliaire 46 contraint le poussoir principal 14 à franchir élastiquement le ressort constituant les moyens d'accrochage 15, en provoquant temporairement une extension radiale de ceux-ci, tel que schématisé par les flèches F2 sur la figure 5A.The driving-in movement of the control member 16 being continued, the auxiliary pusher 46 forces the main pusher 14 to pass elastically through the spring constituting the latching means 15, causing temporarily a radial extension of these, as shown diagrammatically by the arrows F2 in FIG. 5A.

En pratique, le bourrelet 58 du poussoir auxiliaire 46 franchit les moyens d'accrochage 15 en même temps que le bourrelet 52 du poussoir principal 14, conjointement avec celui-ci.In practice, the bead 58 of the auxiliary pusher 46 crosses the hooking means 15 at the same time as the bead 52 of the main pusher 14, together with the latter.

L'action d'enfoncement de l'organe de commande 16 étant poursuivie, figure 5B, le poussoir principal 14, dûment refoulé par le poussoir auxiliaire 46, atteint une position basse, pour laquelle, tel que représenté, son extrémité libre 71 est sensiblement à niveau avec celle 72 de la portion filetée 21 du corps de guidage 12.The driving action of the control member 16 being continued, FIG. 5B, the main pusher 14, duly driven back by the auxiliary pusher 46, reaches a low position, for which, as shown, its free end 71 is substantially level with that 72 of the threaded portion 21 of the guide body 12.

Il vient ainsi agir sur le composant 10, qui, en conséquence, bascule de son premier état à un autre.It thus acts on component 10, which, consequently, switches from its first state to another.

Si, à compter de cet instant, l'organe de commande 16 est relâché, le poussoir auxiliaire 46, et, avec lui, l'organe de commande 16, sont refoulés, par les moyens élastiques d'écartement 47, en direction de la position sortie d'attente de l'organe de commande 16, suivant la flèche F3 de la figure 5C.If, from this instant, the control member 16 is released, the auxiliary pusher 46, and, with it, the control member 16, are pushed back, by the elastic spacing means 47, in the direction of the standby output position of the control member 16, along arrow F3 in FIG. 5C.

Le poussoir auxiliaire 46 vient donc se crocheter, à son tour, par son bourrelet 58, sur le ressort constituant les moyens d'accrochage 15, tel que représenté à la figure 5C, dans le sens axial opposé à celui suivant lequel se faisait précédemment le crochetage du poussoir principal 14 sur ces mêmes moyens d'accrochage 15, et, par construction, il est fait en sorte que la force du ressort constituant les moyens d'écartement 47 soit inférieure à celle nécessaire au franchissement des moyens d'accrochage 15.The auxiliary plunger 46 is therefore hooked, in turn, by its bead 58, on the spring constituting the attachment means 15, as shown in FIG. 5C, in the axial direction opposite to that in which the hooking of the main pusher 14 on these same latching means 15, and, by construction, it is made so that the force of the spring constituting the spacing means 47 is less than that necessary for crossing the latching means 15.

Le poussoir auxiliaire 46 se trouve ainsi retenu par les moyens d'accrochage 15, et, par conséquent, sous la sollicitation des moyens élastiques d'écartement 47, le poussoir principal 14 se trouve lui-même maintenu en position basse dans le corps de guidage 12.The auxiliary pusher 46 is thus retained by the hooking means 15, and, consequently, under the stress of the elastic spacer means 47, the main pusher 14 is itself held in the low position in the guide body. 12.

Le poussoir principal 14 restant ainsi au contact du composant 10, celui-ci demeure dans l'état qui est alors le sien.The main pusher 14 thus remaining in contact with the component 10, the latter remains in the state which is then its own.

En pratique, il en est avantageusement ainsi même si, dès le franchissement des moyens d'accrochage 15, l'organe de commande 16 est inopinément relâché.In practice, this is advantageously so even if, as soon as the hooking means 15 are crossed, the control member 16 is unexpectedly released.

En effet, prenant appui sur le poussoir auxiliaire 46, alors retenu par ces moyens d'accrochage 15, les moyens élastiques d'écartement 47 sont suffisants à eux seuls pour solliciter en direction de sa position basse le poussoir principal 14 et le maintenir dans celle-ci.Indeed, bearing on the auxiliary pusher 46, then retained by these attachment means 15, the elastic spacing means 47 are sufficient in themselves to urge the main pusher 14 towards its lower position and keep it in that -this.

Lorsque le poussoir principal 14 est ainsi en position basse, il retient, en position enfoncée de service, l'organe de commande 16, par les moyens d'attelage à jeu 20 intervenant entre lui et l'axe 19 de cet organe de commande 16.When the main pusher 14 is thus in the low position, it retains, in the depressed service position, the control member 16, by the clearance coupling means 20 acting between it and the axis 19 of this control member 16 .

Conjointement avec l'enfoncement de l'organe de commande 16, le voyant de position 62 est l'objet d'une rotation autour de l'axe 19 de cet organe de commande 16, suivant la flèche F4 de la figure 5A, du fait des moyens de came 67 intervenant entre lui et la bague 27 fixe.In conjunction with the depression of the control member 16, the position indicator 62 is rotated about the axis 19 of this control member 16, along the arrow F4 in Figure 5A, due cam means 67 acting between it and the fixed ring 27.

L'épanouissement 64 qu'il comporte passe ainsi progressivement de sa position escamotée, schématisée en traits interrompus sur la figure 4, à sa position déployée, représentée en traits continus sur les figures 5B et 5C.The opening 64 which it comprises thus progressively passes from its retracted position, shown diagrammatically in broken lines in FIG. 4, to its deployed position, represented in solid lines in FIGS. 5B and 5C.

Pour ramener l'organe de commande 16 en position sortie d'attente, il faut exercer sur celui-ci, suivant la flèche F3 de la figure 5C, une force suffisante pour que le bourrelet 58 du poussoir auxiliaire 46 puisse franchir élastiquement les moyens d'accrochage 15.To return the control member 16 to the standby exit position, it is necessary to exert on it, according to arrow F3 in FIG. 5C, sufficient force so that the bead 58 of the auxiliary pusher 46 can elastically pass through the means of 'hanging 15.

Entraîné par l'organe de commande 16, du fait des moyens d'attelage à jeu 20 intervenant entre lui et celui-ci, le poussoir principal 14 est alors lui-même ramené à sa position haute initiale, tel que représenté sur la figure 4.Driven by the control member 16, due to the play coupling means 20 acting between it and the latter, the main pusher 14 is then itself returned to its initial high position, as shown in FIG. 4 .

Ainsi relâché, le composant 10 revient corollairement lui-même à son premier état.Thus released, the component 10 itself corollarily returns to its first state.

Dans la variante de réalisation représentée sur la figure 6, la tête 18 de l'organe de commande 16 comporte, dans sa zone centrale, un évidement 74, qui, en continuité avec l'alésage 44 de l'axe 19, donne accès aux pattes élastiquement déformables 40 des moyens d'attelage à jeu 20.In the variant embodiment shown in FIG. 6, the head 18 of the control member 16 comprises, in its central zone, a recess 74, which, in continuity with the bore 44 of the axis 19, gives access to the elastically deformable lugs 40 of the play coupling means 20.

Il est ainsi possible d'agir sur celles-ci pour une éventuelle désolidarisation de l'organe de commande 16 vis-à-vis du poussoir principal 14, et, donc, pour un éventuel démontage du bouton de commande 11 dans son ensemble.It is thus possible to act on these for a possible separation of the control member 16 vis-à-vis the main pusher 14, and, therefore, for a possible disassembly of the control button 11 as a whole.

Dans la forme de réalisation représentée, l'évidement 74 est obturé par un bouchon 75 amovible, et celui-ci porte axialement une colonnette 76 qui contrebute les pattes élastiquement déformables 40 des moyens d'attelage à jeu 20, pour éviter que celles-ci échappent inopinément aux évidements 42 avec lesquels elles coopèrent.In the embodiment shown, the recess 74 is closed by a removable plug 75, and the latter carries axially a small column 76 which abuts the elastically deformable lugs 40 of the coupling means with clearance 20, to prevent them from being unexpectedly escape the recesses 42 with which they cooperate.

En pratique, dans la forme de réalisation représentée, ces évidements 42 sont simplement constitués par un décrochement interne de l'alésage 44 de l'axe 19.In practice, in the embodiment shown, these recesses 42 are simply formed by an internal recess of the bore 44 of the axis 19.

Par exemple, et tel que représenté, le bouchon 75 est vissé dans l'évidement 74.For example, and as shown, the plug 75 is screwed into the recess 74.

Bien entendu, la présente invention ne se limite pas aux formes de réalisation décrites et représentées, mais englobe toute variante d'exécution et/ou de combinaison de leurs divers éléments.Of course, the present invention is not limited to the embodiments described and shown, but encompasses any variant and / or combination of their various elements.
