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, et par exemple un quelconque composant électrique, sous-jacent.The present invention relates generally to the control buttons on which it is necessary to act by depressing to intervene on any component, and for example any electrical component, underlying.

Ces boutons de commande, communément appelés "coups 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 piston, qui, pour action sur le composant sous-jacent, est monté mobile dans le corps de guidage à l'encontre de moyens élastiques de rappel, et un organe de commande, en forme générale de champignon, qui, monté mobile axialement par rapport au corps de guidage, entre une position déployée d'attente et une position enfoncée de service, comporte, d'une part, une tête, pour action de l'usager, et, d'autre part, un axe, pour action sur le piston, et, par celui-ci, sur le composant sous-jacent.These control buttons, commonly called "punches" 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 piston , which, for action on the underlying component, is mounted to move in the guide body against elastic return means, and a control member, in the general shape of a mushroom, which, mounted axially movable relative to the guide body, between a deployed waiting position and a depressed service position, comprises, on the one hand, a head, for action by the user, and, on the other hand, an axis, for action on the piston , and, by it, on the underlying component.

La présente invention vise plus particulièrement le cas où, s'agissant de boutons de commande communément dits "à accrochage de type pousser-tourner", il est en outre prévu une bague de maintien, qui, fixe axialement par rapport au corps de guidage et bloquée en rotation par rapport à celui-ci, s'étend autour de l'axe de l'organe de commande, avec, sous la dépendance de cette bague de maintien, d'une part, des moyens d'accrochage, propres à retenir de manière débrayable en position enfoncée l'organe de commande lorsqu'il a été agi en conséquence sur celui-ci, et, d'autre part, des moyens de came propres à assurer un retour de cet organe de commande à sa position angulaire initiale lorsque, ayant été tourné en position enfoncée pour provoquer le débrayage des moyens d'accrochage, il est relâché.The present invention relates more particularly to the case where, in the case of control buttons commonly known as "push-turn type latching", there is further provided a retaining ring, which, axially fixed relative to the guide body and locked in rotation relative to the latter, extends around the axis of the control member, with, under the dependence of this retaining ring, on the one hand, attachment means, suitable for retaining disengageably in the depressed position the control member when it has been acted on thereon, and, on the other hand, cam means suitable for ensuring a return of this control member to its initial angular position when, having been rotated in the depressed position to cause disengagement of the fastening means, it is released.

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 certaines applications, au moins, il apparaît souhaitable que la position, sortie ou enfoncée, de l'organe de commande, soit clairement signalée, la course de l'organe de commande de l'une à l'autre de ses positions étant en générale trop faible pour que le seul examen de celui-ci permette d'en déterminer sans ambiguïté la position.For certain applications, at least, it appears desirable that the position, extended or depressed, of the control member, be clearly indicated, the stroke of the control member from one to the other of its positions being in general too weak for the sole examination of it to determine its position unambiguously.

Sous un premier aspect, la présente invention a d'une manière générale pour objet une disposition permettant de répondre de manière particulièrement simple et efficace à cette exigence.In a first aspect, the present invention generally relates to a provision making it possible to respond in a particularly simple and effective manner to this requirement.

De manière plus précise, elle a pour objet, sous ce premier aspect, un bouton de commande du genre concerné, c'est-à-dire du genre comportant un corps de guidage, par lequel il est adapté à être monté sur un quelconque support, un piston, qui, pour action sur un quelconque composant sous-jacent, est monté mobile dans ce corps de guidage à l'encontre de moyens élastiques de rappel, 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, d'une part, une tête, pour action de l'usager, et, d'autre part, un axe, pour action sur le piston, et une bague de maintien, qui, fixe axialement par rapport au corps de guidage et bloquée en rotation par rapport à celui-ci, s'étend autour de l'axe de l'organe de commande, avec, sous la dépendance de cette bague de maintien, d'une part, des moyens d'accrochage, propres à retenir de manière débrayable en position enfoncée l'organe de commande lorsqu'il a été agi en conséquence sur celui-ci, et, d'autre part, des moyens de came, propres à assurer un retour de l'organe de commande à sa position angulaire initiale lorsque, ayant été tourné en position enfoncée pour provoquer le débrayage des moyens d'accrochage, il est relâché, ce bouton de commande étant d'une manière générale caractérisé en ce que, à l'organe de commande, est associé 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, et une position déployée, lorsque l'organe de commande est en position enfoncée, et dont une portion, au moins, cachée en position escamotée, devient apparente en position déployée.More specifically, it relates, under this first aspect, to a control button of the type concerned, that is to say of the type comprising a guide body, by which it is adapted to be mounted on any support , a piston, which, for action on any underlying component, is mounted movable in this guide body against elastic return means, a control member, which, mounted axially movable relative to the guide body , between a standby position, and a depressed service position, comprises, on the one hand, a head, for action by the user, and, on the other hand, an axis, for action on the piston, and a retaining ring, which, axially fixed relative to the guide body and locked in rotation relative to the latter, extends around the axis of the control member, with, depending on this ring maintenance, on the one hand, of the hooking means, suitable for retaining disengageably in the depressed position the control member when it has been acted on thereon, and, on the other hand, cam means, capable of ensuring a return of the control member to its initial angular position when, having been turned in the depressed position to cause the disengagement of the fastening means, it is released, this control button being generally characterized in that, with the control member, is associated a position indicator, which is mounted movable between two positions, namely a retracted position, when the control member is in the extended position, and a deployed position, when the control member is in the depressed position, and at least a portion of which is hidden in the retracted position , becomes apparent in the deployed position.

Par exemple, suivant une forme préférentielle de réalisation, le voyant de position est monté rotatif autour de l'axe de l'organe de commande et il comporte, d'une part, un moyeu, par lequel il entoure à rotation cet axe tout en étant calé axialement sur celui-ci, et, d'autre part, un épanouissement, qui s'étend sous la tête de l'organe de commande, en formant par exemple lui-même une tête au moins pour partie complémentaire de celle de l'organe de commande, et, conjointement, d'une part, la tête de l'organe de commande comporte localement, sur le trajet de cet épanouissement, au moins un ajour, tel que fenêtre ou encoche, et, d'autre part, pour la commande en rotation du voyant de position, des moyens de came sont prévus entre ce voyant de position et la bague de maintien.For example, according to a preferred embodiment, the position indicator is rotatably mounted around the axis of the control member and it comprises, on the one hand, a hub, by which it rotatably surrounds this axis while being axially wedged thereon, and, on the other hand, a development, which extends under the head of the control member, for example itself forming a head at least partly complementary to that of the control member, and, jointly, on the one hand, the head of the control member comprises locally, on the path of this expansion, at least one aperture, such as window or notch, and, on the other hand, for the rotation control of the position indicator, cam means are provided between this indicator position and the retaining ring.

Ainsi, suivant la position, sortie ou enfoncée, de l'organe de commande, n'est alternativement apparente que telle ou telle portion, dûment repérée en conséquence, de l'épanouissement du voyant de position.Thus, depending on the position, extended or depressed, of the control member, is alternatively only apparent from such and such a portion, duly identified as a result, of the development of the position indicator.

Quoi qu'il en soit, par son passage d'une position escamotée à une position déployée, ce voyant de position signale clairement la position, sortie ou enfoncée, de l'organe de commande.Anyway, by passing from a retracted position to a deployed position, this position indicator clearly indicates the position, extended or depressed, of the control member.

Pour certaines applications, au moins, il apparaît également souhaitable que le retour de l'organe de commande de sa position enfoncée à sa position sortie ne puisse pas résulter d'une simple action fortuite de rotation exercée de manière malencontreuse sur cet organe de commande, par exemple en effleurant sans le vouloir ce dernier.For certain applications, at least, it also appears desirable that the return of the control member from its depressed position to its extended position cannot be the result of a simple fortuitous action of rotation exerted inadvertently on this control member, for example by unintentionally touching the latter.

Sous un deuxième aspect, et suivant un développement de l'invention, le bouton de commande suivant l'invention comporte en outre, pour répondre à cette exigence, des moyens de verrouillage, qui, sous des modalités possibles de réalisation très diverses, sont propres à assurer de manière débrayable le blocage en position enfoncée de l'organe de commande lorsqu'il a été précédemment agi en conséquence sur celui-ci.In a second aspect, and according to a development of the invention, the control button according to the invention further comprises, to meet this requirement, locking means, which, under very different possible embodiments, are specific to disengageably ensure the locking in the depressed position of the control member when it has previously been acted on accordingly.

Par exemple, pour libérer alors cet organe de commande, il faut agir en traction sur lui avant de lui appliquer la rotation nécessaire à son retour de sa position enfoncée à sa position sortie, ou après cette application.For example, to then release this control member, it is necessary to act in traction on it before applying to it the rotation necessary for its return from its depressed position to its exit position, or after this application.

En variante, il faut enfoncer un poussoir prévu à cet effet dans l'axe de son organe de commande.As a variant, a push-button provided for this purpose must be depressed in the axis of its control member.

Dans tous les cas, une action positive et volontaire est avantageusement nécessaire.In all cases, positive and voluntary action is advantageously necessary.

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 que, par exemple, un interrupteur.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, for example, a switch.

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 7, il est adapté à être monté sur un quelconque support 13, un piston 14, qui, pour action sur le composant 10 sous-jacent, est monté mobile dans le corps de guidage 12 à l'encontre de moyens élastiques de rappel 15 formés, dans les formes de réalisation représentées, par un simple ressort du type ressort à boudin, 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, figures 1 et 7, et une position enfoncée de service, figures 2 et 8, comporte, d'une part, une tête 18, pour action de l'usager, et, d'autre part, un axe 19, pour action sur le piston 14, et une bague de maintien 20, qui, fixe axialement par rapport au corps de guidage 12 et bloquée en rotation par rapport à celui-ci, s'étend autour de l'axe 19 de l'organe de commande 16, avec, sous la dépendance de cette bague de maintien 20, et suivant des dispositions décrites plus en détail ultérieurement, d'une part, des moyens d'accrochage 21, propres à retenir de manière débrayable en position enfoncée l'organe de commande 16 lorsqu'il a été agi en conséquence sur celui-ci, et, d'autre part, des moyens de came 22 propres à assurer un retour de l'organe de commande 16 à sa position angulaire initiale lorsque, ayant été tourné en position enfoncée pour provoquer le débrayage des moyens d'accrochage 21, il est relâché.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. 7, it is adapted to be mounted on any support 13, a piston 14, which, for action on the underlying component 10, is mounted mobile in the guide body 12 against elastic return means 15 formed, in the embodiments shown, by a simple spring of the coil spring type, a control member 16, in the general shape of a mushroom, which, mounted axially movable relative to the guide body 12, between a standby position, FIGS. 1 and 7, and a depressed service position , Figures 2 and 8, comprises, on the one hand, a head 18, for user action, and, on the other hand, a pin 19, for action on the piston 14, and a retaining ring 20, which , axially fixed relative to the guide body 12 and locked in rotation relative to to it, extends around the axis 19 of the control member 16, with, under the dependence of this retaining ring 20, and according to arrangements described more in detail later, on the one hand, hooking means 21, capable of releasably detaching in the depressed position the control member 16 when it has been acted on thereon, and, on the other hand, cam means 22 capable of ensuring a return of the control member 16 to its initial angular position when, having been rotated in the depressed position to cause the disengagement of the hooking means 21, it is released.

Par exemple, et tel que schématisé sur les figures 7 à 9, le support 13 est une simple plaque dans un évidement 23 de laquelle le corps de guidage 12 est engagé par une portion filetée 24.For example, and as shown diagrammatically in FIGS. 7 to 9, the support 13 is a simple plate in a recess 23 from which the guide body 12 is engaged by a threaded portion 24.

D'un côté, le corps de guidage 12 prend appui contre le support 13 par un épaulement 25, par l'intermédiaire d'un joint d'étanchéité 26, et, de l'autre côté, un écrou 27 est vissé sur sa portion filetée 24 pour son blocage en position sur ce support 13.On one side, the guide body 12 bears against the support 13 by a shoulder 25, by means of a seal 26, and, on the other side, a nut 27 is screwed on its portion threaded 24 for locking it in position on this support 13.

Dans les formes de réalisation représentées, le piston 14 porte annulairement un joint 28, et il s'agit en pratique d'un joint à lèvre.In the embodiments shown, the piston 14 annularly carries a seal 28, and it is in practice a lip seal.

Les moyens élastiques de rappel 15 prennent appui sur un épaulement interne 29 du corps de guidage 12 et portent sur un épaulement externe 30 du piston 14.The elastic return means 15 bear on an internal shoulder 29 of the guide body 12 and bear on an external shoulder 30 of the piston 14.

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 31.In the embodiments shown, the head 18 of the control member 16 has a circular outline in plan, and it peripherally comprises a skirt 31.

La bague de maintien 20 est maintenue appliquée contre un épaulement 32 du corps de guidage 12 par une douille 34 vissée dans une portion taraudée 35 de ce corps de guidage 12.The retaining ring 20 is kept applied against a shoulder 32 of the guide body 12 by a bush 34 screwed into a threaded portion 35 of this guide body 12.

Pour son blocage en rotation sur le corps de guidage 12, la bague de maintien 20 présente, en saillie, des ergots 37 par lesquels elle est en prise avec des évidements 38 prévus de manière complémentaire sur l'épaulement 32 de ce corps de guidage 12.For locking in rotation on the guide body 12, the retaining ring 20 has, projecting, lugs 37 by which it is engaged with recesses 38 provided in a complementary manner on the shoulder 32 of this guide body 12 .

Les moyens d'accrochage 21 comportent deux parties, une partie 21A, qui concerne la bague de maintien 20, et une partie 21B, qui concerne l'organe de commande 16.The attachment means 21 comprise two parts, a part 21A, which relates to the retaining ring 20, and a part 21B, which relates to the control member 16.

La partie 21A est constituée par une simple épingle en U qui, par ses ailes latérales 40, est engagée transversalement sur la bague de maintien 20, à la faveur de perçages 41 affectant intérieurement à mi-épaisseur la paroi latérale de celle-ci.The part 21A is constituted by a simple U-shaped pin which, by its lateral wings 40, is engaged transversely on the retaining ring 20, by means of holes 41 internally affecting the lateral wall thereof at mid-thickness.

Lorsque l'épingle constituant ainsi la partie 21A des moyens d'accrochage 21 est en prise avec la bague de maintien 20, ses ailes latérales 40 font légèrement saillie dans le volume interne de celle-ci, comme schématisé en traits interrompus sur la figure 5.When the pin thus constituting the part 21A of the hooking means 21 is engaged with the retaining ring 20, its lateral wings 40 protrude slightly in the internal volume thereof, as shown diagrammatically in broken lines in FIG. 5 .

La partie 21B des moyens d'accrochage 21 concernant l'organe de commande 16 comporte, échelonnées en hauteur, et dûment calées en rotation sur l'axe 19 de cet organe de commande 16, deux paires de crans 42, 43, les crans 42 pour la retenue en position sortie de l'organe de commande 16, et les crans 43 pour sa retenue en position enfoncée.Part 21B of the hooking means 21 relating to the control member 16 comprises, staggered in height, and duly locked in rotation on the axis 19 of this control member 16, two pairs of notches 42, 43, the notches 42 for retaining in the extended position of the control member 16, and the notches 43 for retaining it in the depressed position.

Les crans 42 ont un flanc oblique 44 du côté opposé à la tête 18 de l'organe de commande 16, pour que, au montage, ils puissent franchir les ailes latérales 40 de l'épingle formant la partie 21A des moyens d'accrochage 21 par simple déformation élastique temporaire de ces ailes latérales 40, et un flanc droit 45 du côté de la tête 18 de l'organe de commande 16.The notches 42 have an oblique flank 44 on the side opposite to the head 18 of the control member 16, so that, during assembly, they can cross the lateral wings 40 of the pin forming the part 21A of the hooking means 21 by simple temporary elastic deformation of these lateral wings 40, and a straight flank 45 on the side of the head 18 of the control member 16.

Il en est de même, en pratique, des crans 43.It is the same, in practice, notches 43.

Les moyens de came 22 comportent eux aussi deux parties, une partie 22A, qui concerne la bague de maintien 20, et une partie 22B, qui concerne l'organe de commande 16.The cam means 22 also comprise two parts, a part 22A, which relates to the retaining ring 20, and a part 22B, which relates to the control member 16.

La partie 22A est constituée de deux ergots 46 que la bague de maintien 20 présente radialement en saillie sur sa surface intérieure, en positions diamétralement opposées l'un par rapport à l'autre.Part 22A consists of two lugs 46 which the retaining ring 20 has radially projecting from its inner surface, in diametrically opposite positions relative to one another.

La partie 22B comporte, en correspondance, deux rampes hélicoïdales 47, qui sont calées en rotation sur l'axe 19 de l'organe de commande 16, et qui communiquent chacune avec une rainure 48 allongée parallèlement à l'axe de l'ensemble à leur extrémité opposée à la tête 18 de cet organe de commande 16.Part 22B comprises, in correspondence, two helical ramps 47, which are set in rotation on the axis 19 of the control member 16, and which each communicate with a groove 48 elongated parallel to the axis of the assembly to their end opposite to the head 18 of this control member 16.

Les dispositions qui précèdent sont bien connues par elles-mêmes, et elles ne seront donc pas décrites plus en détail ici.The foregoing provisions are well known in themselves, and therefore will not be described in more detail here.

Suivant l'invention, il est associé, à l'organe de commande 16, un voyant de position 50, qui est monté mobile entre deux positions, à savoir une position escamotée, figures 1 et 7, lorsque l'organe de commande 16 est en position sortie, et une position déployée, figures 2 et 8, lorsque l'organe de commande 16 est en position enfoncée, et dont une portion au moins, cachée en position escamotée, est apparente en position déployée.According to the invention, it is associated with the control member 16, a position indicator 50, which is mounted movable between two positions, namely a retracted position, Figures 1 and 7, when the control member 16 is in the extended position, and a deployed position, FIGS. 2 and 8, when the control member 16 is in the depressed position, and at least a portion of which, hidden in the retracted position, is visible in the deployed position.

Dans les formes de réalisation représentées, ce voyant de position 50 est monté rotatif autour de l'axe 19 de l'organe de commande 16.In the embodiments shown, this position indicator 50 is mounted to rotate about the axis 19 of the control member 16.

En pratique, il comporte, globalement, d'une part, un moyeu 51, par lequel il entoure à rotation l'axe 19 de l'organe de commande 16 tout en étant calé axialement sur celui-ci, et, d'autre part, un épanouissement 52, qui s'étend sous la tête 18 de l'organe de commande 16.In practice, it comprises, overall, on the one hand, a hub 51, by which it rotatably surrounds the axis 19 of the control member 16 while being wedged axially thereon, and, on the other hand , a development 52, which extends under the head 18 of the control member 16.

Dans les formes de réalisation représentées, le moyeu 51 est fragmenté en pattes 53 qui toutes présentent, en saillie sur leur surface intérieure, au voisinage de leur extrémité libre, un ergot 54 par lequel elles sont conjointement en prise avec une gorge 55 prévue annulairement à cet effet sur l'axe 19 de l'organe de commande 16.In the embodiments shown, the hub 51 is fragmented into lugs 53 which all have, projecting from their inner surface, in the vicinity of their free end, a lug 54 by which they are jointly engaged with a groove 55 provided annularly at this effect on the axis 19 of the control member 16.

Dans les formes de réalisation représentées, l'épanouissement 52 forme conjointement une tête qui est au moins pour partie complémentaire de la tête 18 de l'organe de commande 16, et qui, notamment, présente, périphériquement, comme celle-ci, une jupe 56.In the embodiments shown, the opening 52 jointly forms a head which is at least partially complementary to the head 18 of the control member 16, and which, in particular, has, peripherally, like this one, a skirt 56.

Dans la forme de réalisation plus particulièrement représentée sur les figures 1 à 8, le voyant de position 50 ainsi constitué est monobloc, mais, ainsi qu'il apparaîtra ultérieurement, il n'en est pas nécessairement ainsi.In the embodiment more particularly shown in Figures 1 to 8, the position indicator 50 thus formed is in one piece, but, as will appear later, it is not necessarily so.

Quoi qu'il en soit, suivant l'invention, la tête 18 de l'organe de commande 16 comporte, localement, sur le trajet de l'épanouissement 52 du voyant de position 50, au moins un ajour 57, 57', tel que fenêtre 57 ou encoche 57', laissant à vue ce voyant de position 50.Anyway, according to the invention, the head 18 of the control member 16 comprises, locally, on the path of the opening 52 of the position indicator 50, at least one aperture 57, 57 ', such as window 57 or notch 57', leaving this position indicator 50 visible.

En pratique, dans la forme de réalisation représentée sur les figures 1 à 8, la tête 18 de l'organe de commande 16 comporte, d'une part, un ajour 57 isolé, qui affecte sa paroi de façade, et forme donc une fenêtre, de contour fermé, et, d'autre part, une pluralité d'ajours 57', qui, régulièrement répartis circulairement, affectent sa jupe 31.In practice, in the embodiment shown in FIGS. 1 to 8, the head 18 of the control member 16 comprises, on the one hand, an isolated aperture 57, which affects its front wall, and therefore forms a window , of closed contour, and, on the other hand, a plurality of openings 57 ', which, regularly distributed circularly, affect its skirt 31.

Tel que représenté en traits continus, ces ajours 57' sont des encoches, de contour ouvert, parce que, dans cette forme de réalisation, la jupe 31 de la tête 18 de l'organe de commande 16 a une hauteur réduite.As shown in solid lines, these openings 57 'are notches, of open outline, because, in this embodiment, the skirt 31 of the head 18 of the control member 16 has a reduced height.

Mais, en variante, et tel que schématisé en traits interrompus sur la figure 7, cette jupe 31 peut avoir une hauteur suffisante pour que la tête 18 de l'organe de commande 16 recouvre complètement l'épanouissement 52 du voyant de position 50, en empêchant ainsi avantageusement d'avoir accès à la jupe 56 de celui-ci.However, as a variant, and as shown diagrammatically in broken lines in FIG. 7, this skirt 31 may have a height sufficient for the head 18 of the control member 16 to completely cover the opening 52 of the position indicator 50, in thus advantageously preventing access to the skirt 56 thereof.

Dans ce cas, et comme l'ajour 57, les ajours 57' sont des fenêtres de contour fermé.In this case, and like the aperture 57, the apertures 57 ′ are windows of closed outline.

Si désiré, les ajours 57, 57' sont occultés par des hublots translucides, non représentés, pour minimiser les risques d'encrassement pour le voyant de position 50.If desired, the openings 57, 57 ′ are obscured by translucent windows, not shown, to minimize the risk of fouling for the position indicator 50.

En correspondance avec l'ajour 57, et sur la même circonférence que celui-ci, l'épanouissement 52 du voyant de position 50 comporte un repère 59, qui est masqué pour la position sortie de l'organe de commande 16, figure 1, et qui est démasqué pour sa position enfoncée, figure 2.In correspondence with the aperture 57, and on the same circumference as the latter, the opening 52 of the position indicator 50 includes a mark 59, which is hidden for the position extended from the control member 16, FIG. 1, and which is unmasked for its depressed position, Figure 2.

Il s'agit, en l'espèce, d'un repère littéral, tel que, par exemple, et tel que représenté, la mention "stop".It is, in this case, a literal mark, such as, for example, and as shown, the mention "stop".

De même, en correspondance avec les ajours 57', et sur la même circonférence que ceux-ci, l'épanouissement 52 du voyant de position 50, et, plus précisément, la jupe 56 de cet épanouissement 52, comporte, en nombre égal, une pluralité de repères 59'.Similarly, in correspondence with the openings 57 ′, and on the same circumference as the latter, the opening 52 of the position indicator 50, and, more precisely, the skirt 56 of this opening 52, comprises, in equal number, a plurality of marks 59 '.

Il s'agit, par exemple, et tel que schématisé sur la figure 2, de repères colorés.These are, for example, and as shown diagrammatically in FIG. 2, colored markers.

Pour la commande en rotation du voyant de position 50, des moyens de came 60 sont prévus entre ce voyant de position 50 et la bague de maintien 20.To control the position indicator 50 in rotation, cam means 60 are provided between this position indicator 50 and the retaining ring 20.

Dans les formes de réalisation représentées, ces moyens de came 60 comportent, d'une part, sur la bague de maintien 20, au moins une rainure hélicoïdale 60A, qui affecte en creux la surface intérieure de cette bague de maintien 20 en débouchant parallèlement à l'axe de l'ensemble du côté de la tête 18 de l'organe de commande 16, et, d'autre part, en correspondance, sur le voyant de position 50, au moins un ergot 60B, qui s'étend radialement en saillie sur le moyeu 51 de ce voyant de position 50, à la base de ce moyeu 51, et qui est en prise avec la rainure hélicoïdale 60A de la bague de maintien 20.In the embodiments shown, these cam means 60 comprise, on the one hand, on the retaining ring 20, at least one helical groove 60A, which hollow affects the inner surface of this retaining ring 20 by opening parallel to the axis of the assembly on the side of the head 18 of the control member 16, and, on the other hand, in correspondence, on the position indicator 50, at least one lug 60B, which extends radially in projection on the hub 51 of this position indicator 50, at the base of this hub 51, and which is in engagement with the helical groove 60A of the retaining ring 20.

En pratique, deux rainures hélicoïdales 60A sont prévues en positions diamétralement opposées l'une par rapport à l'autre, et, donc, en correspondance, deux ergots 60B.In practice, two helical grooves 60A are provided in diametrically opposite positions with respect to each other, and, therefore, in correspondence, two pins 60B.

Dans la forme de réalisation plus particulièrement représentée sur les figures 1 à 8, et il en est de même dans les variantes de réalisation représentées sur les figures 11 à 16, le bouton de commande 11 suivant l'invention comporte, en outre, des moyens de verrouillage propres à assurer de manière débrayable le blocage en position enfoncée de l'organe de commande 16 lorsqu'il a été précédemment agi en conséquence sur celui-ci.In the embodiment more particularly shown in Figures 1 to 8, and it is the same in the alternative embodiments shown in Figures 11 to 16, the control button 11 according to the invention further comprises means of locking capable of disengageably ensuring the locking in the depressed position of the control member 16 when it has previously been acted on accordingly.

Dans la forme de réalisation représentée sur les figures 1 à 8, ces moyens de verrouillage comportent des moyens d'emboîtement 62 complémentaires, qui, tel que décrit ci-après, interviennent axialement entre l'axe 19 de l'organe de commande 16 et le piston 14, et, conjointement, la partie 21B des moyens d'accrochage 21 concernant l'organe de commande 16 est portée par une douille 63 qui, entourant l'axe 19 de l'organe de commande 16, est montée mobile sur cet axe 19 tout en étant calée en rotation sur celui-ci, en coopération avec des moyens élastiques de polarisation 64, en pratique un ressort du type ressort à boudin, qui, prenant appui sur l'axe 19 de l'organe de commande 16, sollicitent en permanence la douille 63 en direction d'un épaulement transversal 65 de cet axe 19 tourné du côté opposé à la tête 18 de l'organe de commande 16.In the embodiment shown in FIGS. 1 to 8, these locking means comprise complementary fitting means 62, which, as described below, operate axially between the axis 19 of the control member 16 and the piston 14, and, jointly, the part 21B of the hooking means 21 relating to the control member 16 is carried by a sleeve 63 which, surrounding the axis 19 of the control member 16, is mounted movably on this axis 19 while being locked in rotation thereon, in cooperation with elastic polarization means 64, in practice a spring of the coil spring type, which, bearing on the axis 19 of the control member 16, permanently request the sleeve 63 in the direction of a transverse shoulder 65 of this turned axis 19 on the side opposite to the head 18 of the control member 16.

En pratique, dans la forme de réalisation représentée, les moyens d'emboîtement 62 comportent une nervure 62A, qui s'étend diamétralement en bout de l'axe 19 de l'organe de commande 16, et une saignée 62B qui, en correspondance, s'étend diamétralement de manière complémentaire sur le piston 14.In practice, in the embodiment shown, the fitting means 62 comprise a rib 62A, which extends diametrically at the end of the axis 19 of the control member 16, and a groove 62B which, in correspondence, extends diametrically in a complementary manner on the piston 14.

Sur sa surface intérieure, la douille 63 présente, en creux, de place en place, des rainures 66, qui s'étendent parallèlement à l'axe de l'ensemble, et par lesquelles elle est en prise avec des nervures 67 prévues en correspondance sur l'axe 19 de l'organe de commande 16.On its inner surface, the socket 63 has, in hollow, from place to place, grooves 66, which extend parallel to the axis of the assembly, and by which it is engaged with ribs 67 provided in correspondence on the axis 19 of the control member 16.

Sur sa surface intérieure, la douille 63 présente en outre, en saillie, un épaulement transversal 68, pour l'appui des moyens élastiques de polarisation 64.On its inner surface, the sleeve 63 also has, projecting, a transverse shoulder 68, for the support of the elastic polarization means 64.

Conjointement, l'axe 19 de l'organe de commande 16 présente, lui-même, radialement en saillie de place en place sur sa surface extérieure, pour l'appui de ces moyens élastiques de polarisation 64, un épaulement transversal 70.Jointly, the axis 19 of the control member 16 has, itself, radially projecting from place to place on its outer surface, for the support of these elastic polarization means 64, a transverse shoulder 70.

Outre les crans 42, 43 formant la partie 21B des moyens d'accrochage 21 concernant l'organe de commande 16, la douille 63 porte, sur sa surface extérieure, les rampes hélicoïdales 47 formant la partie 22B des moyens de came 22 intervenant entre cet organe de commande 16 et la bague de maintien 20.In addition to the notches 42, 43 forming the part 21B of the hooking means 21 relating to the control member 16, the sleeve 63 carries, on its outer surface, the helical ramps 47 forming the part 22B of the cam means 22 acting between this control member 16 and the retaining ring 20.

En alternance avec les crans 43, et ainsi qu'il est mieux visible sur la figure 4, elle présente également, sur sa surface extérieure, des méplats 72, qui sont décalés circulairement par rapport aux crans 43, mais en regard desquels s'étendent encore les crans 42, ces crans 42 ayant circulairement un développement supérieur à celui des crans 43.Alternating with the notches 43, and as is better visible in FIG. 4, it also has, on its outer surface, flats 72, which are circularly offset with respect to the notches 43, but opposite which extend again the notches 42, these notches 42 having a circular development greater than that of the notches 43.

Pour la position sortie de l'organe de commande 16, figures 1 et 7, l'épingle constituant la partie 21A des moyens d'accrochage 21 est en prise avec les crans 42 de la douille 63, ce qui cale axialement cette douille 63 par rapport à la bague de maintien 20, et, donc, par rapport au corps de guidage 12.For the extended position of the control member 16, FIGS. 1 and 7, the pin constituting the part 21A of the hooking means 21 is engaged with the notches 42 of the socket 63, which axially holds this socket 63 by relative to the retaining ring 20, and therefore relative to the guide body 12.

Sous la sollicitation des moyens élastiques de rappel 15, le piston 14 est en position haute, en butée contre la douille 63.Under the stress of the elastic return means 15, the piston 14 is in the high position, in abutment against the bush 63.

Il est donc escamoté dans le corps de guidage 12, et, ce piston 14 n'ayant de ce fait aucune action sur lui, le composant 10 est dans un premier état.It is therefore retracted into the guide body 12, and, this piston 14 therefore having no action on it, the component 10 is in a first state.

Sous la sollicitation des moyens élastiques de polarisation 64, qui prennent appui sur la douille 63, l'organe de commande 16 est conjointement en prise par sa nervure 62A avec la saignée 62B du piston 14.Under the bias of the elastic biasing means 64, which bear on the sleeve 63, the control member 16 is jointly engaged by its rib 62A with the groove 62B of the piston 14.

Conjointement, enfin, les repères 59, 59' du voyant de position 50 sont invisibles.Finally, finally, the marks 59, 59 ′ of the position indicator 50 are invisible.

Si, suivant la flèche F1 des figures 1 et 7, une action d'enfoncement est exercée axialement sur l'organe de commande 16, cet organe de commande 16 passe de sa position sortie à sa position enfoncée, figures 2 et 8, et il refoule avec lui la douille 63, et, par celle-ci, le piston 14.If, according to the arrow F1 of FIGS. 1 and 7, a driving action is exerted axially on the control member 16, this control member 16 passes from its extended position to its depressed position, FIGS. 2 and 8, and it pushes with it the sleeve 63, and, by the latter, the piston 14.

Sous l'action du piston 14, qui fait alors légèrement saillie hors du corps de guidage 12, le composant 10 passe de son premier état à un deuxième, différent du premier.Under the action of the piston 14, which then projects slightly out of the guide body 12, the component 10 changes from its first state to a second, different from the first.

Conjointement, du fait du refoulement de la douille 63 par l'organe de commande 16, les crans 43 de cette douille 63 franchissent élastiquement les ailes latérales 40 de l'épingle formant la partie 21A des moyens d'accrochage 21, et se crochètent sur celles-ci, ce qui maintient en position enfoncée cette douille 63, et, donc, par elle, du fait des moyens élastiques de polarisation 64, l'organe de commande 16.Jointly, due to the discharge of the sleeve 63 by the control member 16, the notches 43 of this sleeve 63 elastically cross the lateral wings 40 of the pin forming the part 21A of the hooking means 21, and hook on these, which hold this socket 63 in the depressed position, and therefore, by it, due to the elastic polarization means 64, the control member 16.

Conjointement, les ergots 60B du voyant de position 50, qui est lui aussi entraîné axialement par l'organe de commande 16, ont parcouru les rainures hélicoïdales 60A de la bague de maintien 20.At the same time, the pins 60B of the position indicator 50, which is also driven axially by the control member 16, have passed through the helical grooves 60A of the retaining ring 20.

Cette bague de maintien 20 étant calée en rotation sur le corps de guidage 12, il en résulte une rotation du voyant de position 50 autour de l'axe 19 de l'organe de commande 16, suivant, par exemple, la flèche F2 des figures 2 et 3.This retaining ring 20 being locked in rotation on the guide body 12, this results in a rotation of the position indicator 50 around the axis 19 of the control member 16, according, for example, to the arrow F2 in the figures 2 and 3.

Au terme de cette rotation, les repères 59, 59' du voyant de position 50 sont exactement en regard des ajours 57, 57' de l'organe de commande 16 ; ils sont donc dès lors apparents, comme représenté sur la figure 2.At the end of this rotation, the marks 59, 59 ′ of the position indicator 50 are exactly opposite the openings 57, 57 'of the control member 16; they are therefore therefore apparent, as shown in FIG. 2.

Pour ramener en position sortie l'organe de commande 16, et ainsi libérer le composant 10, il faut tout d'abord le déverrouiller.To return the control member 16 to the extended position, and thus release the component 10, it must first be unlocked.

Il faut, pour cela, exercer sur cet organe de commande 16, suivant la flèche F3 des figures 2 et 8, une traction suffisante pour que la nervure 62A de son axe 19 échappe à la saignée 62B du piston 14, tel que schématisé en traits interrompus sur la figure 8.For this, it is necessary to exert on this control member 16, along arrow F3 of FIGS. 2 and 8, sufficient traction so that the rib 62A of its axis 19 escapes from the groove 62B of the piston 14, as shown diagrammatically in lines interrupted in Figure 8.

Il faut, ensuite, ce qui était jusque-là impossible, faire tourner l'organe de commande 16, suivant la flèche F4 de la figure 2, d'une quantité suffisante pour que les crans 43 de la douille 63, entraînée par lui, échappent aux ailes latérales 40 de l'épingle constituant la partie 21A des moyens d'accrochage 21, et que, ainsi libérée, et sous la sollicitation des moyens élastiques de rappel 15, la douille 63 glisse au contact de ces ailes latérales 40 jusqu'à venir à nouveau en prise avec celles-ci par ses crans 42, en entraînant, avec elle, du fait des moyens élastiques de polarisation 64, l'organe de commande 16.It is then necessary, which was hitherto impossible, to rotate the control member 16, along arrow F4 in FIG. 2, by an amount sufficient for the notches 43 of the sleeve 63, driven by it, escape the lateral wings 40 of the pin constituting the part 21A of the hooking means 21, and that, thus released, and under the stress of the elastic return means 15, the sleeve 63 slides in contact with these lateral wings 40 up to coming back into engagement with them by its notches 42, driving with it, due to the elastic polarization means 64, the control member 16.

Lors de son retour en position axiale initiale, la douille 63 est conjointement ramenée dans sa position angulaire initiale par la bague de maintien 20, du fait des moyens de came 22 intervenant entre elle et celle-ci, et elle entraîne en rotation avec elle l'organe de commande 16, qui est donc lui aussi ramené à sa position angulaire initiale.Upon returning to the initial axial position, the sleeve 63 is jointly returned to its initial angular position by the retaining ring 20, due to the cam means 22 acting between it and the latter, and it rotates with it l 'control member 16, which is therefore also returned to its initial angular position.

De même, le voyant de position 50 est ramené en position angulaire initiale par la bague de maintien 20, du fait des moyens de came 60 intervenant entre lui et celle-ci.Likewise, the position indicator 50 is returned to the initial angular position by the retaining ring 20, due to the cam means 60 acting between it and the latter.

Les repères 59, 59' de ce voyant de position 50 sont donc à nouveau invisibles.The marks 59, 59 ′ of this position indicator 50 are therefore invisible again.

Dans la variante de réalisation représentée sur la figure 9, il n'est prévu aucun moyen de verrouillage pour l'organe de commande 16.In the variant embodiment shown in FIG. 9, no locking means is provided for the control member 16.

Les crans 42, 43 formant la partie 21B des moyens d'accrochage 21 concernant cet organe de commande 16 sont donc de manière usuelle directement portés par son axe 19, et il en est de même pour les rampes hélicoïdales 47, non visibles sur la figure 9, formant la partie 22B des moyens de came 22 intervenant entre cet organe de commande 16 et la bague de maintien 20.The notches 42, 43 forming part 21B of the fastening means 21 relating to this control member 16 are therefore usually directly carried by its axis 19, and it is the same for the helical ramps 47, not visible in Figure 9, forming part 22B of the cam means 22 acting between this control member 16 and the retaining ring 20.

En outre, dans cette variante de réalisation, le voyant de position 50 est en deux pièces 50', 50'', qui, solidaires l'une de l'autre, sont de couleurs différentes, et dont une, la pièce 50', visible isolément sur la figure 10, forme directement par elle-même, outre le repère 59, les repères 59', en contraste avec l'autre.In addition, in this alternative embodiment, the position indicator 50 is in two parts 50 ′, 50 ″, which, integral with one another, are of different colors, and one of which, the part 50 ′, visible in isolation in FIG. 10, forms directly by itself, in addition to the reference 59, the references 59 ′, in contrast with the other.

Pour le reste, les dispositions sont du même type que celles précédemment décrites.For the rest, the provisions are of the same type as those previously described.

Dans la variante de réalisation représentée sur les figures 11 à 13, les moyens de verrouillage associés à l'organe de commande 16 comportent, radialement en saillie sur l'axe 19 de celui-ci, en alternance, circulairement, avec les crans 43 que comporte cet axe 19 pour participer à la constitution de la partie 21B des moyens d'accrochage 21 concernant cet organe de commande 16, au moins un cran supplémentaire 43'.In the variant embodiment shown in FIGS. 11 to 13, the locking means associated with the control member 16 comprise, radially projecting on the axis 19 thereof, alternately, circularly, with the notches 43 that comprises this axis 19 to participate in the constitution of the part 21B of the hooking means 21 relating to this control member 16, at least one additional notch 43 '.

En pratique, deux crans supplémentaires 43' sont prévus, à niveau avec les crans 43, et adjacents, chacun respectivement, à ceux-ci.In practice, two additional notches 43 ′ are provided, level with the notches 43, and adjacent, each respectively, to these.

Mais, à l'inverse des crans 43, les crans supplémentaires 43' ont un flanc oblique 44' du côté de la tête 18 de l'organe de commande 16, et un flanc droit 45' du côté opposé à celle-ci.However, unlike the notches 43, the additional notches 43 'have an oblique flank 44' on the side of the head 18 of the control member 16, and a straight flank 45 'on the opposite side thereof.

Pour ramener en position sortie l'organe de commande 16 lorsqu'il est en position enfoncée, il faut donc tout d'abord le faire tourner d'une quantité suffisante pour que ses crans 43 échappent aux ailes latérales 40 de l'épingle constituant la partie 21A des moyens d'accrochage 21, puis le soumettre à une traction suffisante pour que, par déformation élastique temporaire de ces ailes latérales 40, ses crans supplémentaires 43', alors en prise avec ces ailes latérales 40, franchissent élastiquement celles-ci.To return the control member 16 to the extended position when it is in the depressed position, it must therefore first be rotated by an amount sufficient for its notches 43 to escape the lateral wings 40 of the pin constituting the part 21A of the hooking means 21, then subject it to sufficient traction so that, by temporary elastic deformation of these lateral wings 40, its additional notches 43 ′, then engaged with these lateral wings 40, elastically cross these.

Dans la variante de réalisation représentée sur les figures 14 à 16, les moyens de verrouillage associés à l'organe de commande 16 comportent une clavette 75, qui, sous le contrôle d'un poussoir 76 à la disposition de l'usager, est montée mobile transversalement sur l'axe 19 de l'organe de commande 16, entre une position déployée, pour laquelle elle fait saillie radialement sur cet axe 19, tel que représenté sur les figures 14 et 15, au niveau du ou des crans 43 que comporte celui-ci pour participer à la constitution des moyens d'accrochage 21, et une position rétractée, non représentée, pour laquelle elle est effacée dans cet axe 19.In the alternative embodiment shown in FIGS. 14 to 16, the locking means associated with the control member 16 include a key 75, which, under the control of a push-button 76 available to the user, is mounted movable transversely on the axis 19 of the control member 16, between a deployed position, for which it projects radially on this axis 19, as shown in FIGS. 14 and 15, at the level of the notch (s) 43 which comprise the latter in order to participate in the constitution of the attachment means 21, and a retracted position, not shown, for which it is erased in this axis 19.

En pratique, le poussoir 76 est monté mobile axialement dans un alésage 77 de l'organe de commande 16, qui débouche à l'extérieur sur la tête de celui-ci, et il comporte obliquement un doigt 78 par lequel il est en prise avec une boutonnière 79 de la clavette 75.In practice, the pusher 76 is mounted axially movable in a bore 77 of the control member 16, which opens to the outside on the head thereof, and it obliquely comprises a finger 78 by which it is engaged with a buttonhole 79 of the key 75.

En pratique, également, celle-ci est montée coulissante dans des nervures 80, qui, venues d'un seul tenant de l'axe 19, font saillie transversalement à l'intérieur de celui-ci, et sur lesquelles prennent appui des moyens élastiques de rappel 81, en pratique un simple ressort du type ressort à boudin, associés au poussoir 76.In practice, too, it is slidably mounted in ribs 80, which, coming in one piece from the axis 19, protrude transversely inside thereof, and on which bear elastic means. 81, in practice a simple spring of the coil spring type, associated with the pusher 76.

Conjointement, enfin, le poussoir 76 présente, latéralement, des pattes 82, qui sont conformées en crochets, et par lesquelles il vient en prise, au repos, avec les nervures 80, pour limiter son mouvement de sortie sous la sollicitation des moyens élastiques de rappel 81.At the same time, finally, the pusher 76 has, laterally, tabs 82, which are shaped into hooks, and by which it engages, at rest, with the ribs 80, to limit its outward movement under the stress of the elastic means of reminder 81.

Pour ramener en position sortie l'organe de commande 16 après qu'il ait été enfoncé, il faut, tout d'abord, et comme précédemment, le faire tourner d'une quantité suffisante pour que les crans 43 échappent aux ailes latérales 40 de l'épingle constituant la partie 21A des moyens d'accrochage 21, puis enfoncer le poussoir 76, ce qui fait passer la clavette 75, alors en prise avec l'une de ces ailes latérales 40, de sa position déployée à sa position rétractée.To return the control member 16 to the extended position after it has been pressed, it is first necessary, and as before, to rotate it by an amount sufficient for the notches 43 to escape from the lateral wings 40 of the pin constituting the part 21A of the hooking means 21, then depress the pusher 76, which causes the key 75 to pass, then engaged with one of these lateral wings 40, from its deployed position to its retracted position.

Pour le reste, les dispositions sont du même type que celles précédemment décrites.For the rest, the provisions are of the same type as those previously described.

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