Definitions

  • the invention finds an application in particular in the provision of a manual control device to be fixed to a wall or in the form of a remote control, the actuation of each support zone of which makes it possible to activate or not, selectively, an electrical function intended to be thus controlled by simple pressure on the support zone.
  • Pressing a given support area allows the associated switch to move to the active state, which causes the implementation of the electrical function associated with this switch, in particular by closing an electrical circuit of which the switch is an integral part. Releasing the support area allows the switch to return to its inactive state, and this is the reason for the existence of the aforementioned return mechanism.
  • each support zone is integrated on a common key or on a separate key allowing the use of independent key clusters, or allowing the use of one or more keys directly integrated into the front panel of the manual control device.
  • the return mechanism associated with one or more of these keys is typically in the form of a mechanical spring.
  • the aim of the present invention is to provide a manual control device which is robust, simple, efficient and economical and easily modular.
  • the return mechanism is very simple, efficient, economical, and easy to assemble because it is sufficient to attach the toric element to the receiving elements.
  • the toric element thus attached to the base and/or to the control button advantageously undergoes a local prestress at each intended inflection. This prestress occurs at the time of assembly of the toric element and is then present permanently as long as the control device remains assembled. This prestress results from the local bending of the toric element at each inflection.
  • the fact that the toric element works in bending and not in compression gives it good robustness and great durability.
  • the inflections By forming the inflections, it is possible to hold the control button against the base or the upper cover which will be described later, by a force having a variable intensity by moving along the periphery of the toric element, depending on the position of the inflections and their shape (depth, length, presence of a flat part, value of the inclinations of the inclined parts of the inflection etc.), for example having an intensity, at the locations around which the control button is supposed to be moved, greater than the intensity at each support zone. Maintaining the control button in a stable position against the base and/or against the upper cover is done in a simple, effective and economical way, thanks to the presence of a simple toric element.
  • This solution is in fact very inexpensive thanks to the use of a standard component, easy to assemble with very good elasticity and endurance characteristics.
  • the stiffness of the return mechanism at each location on the periphery of the toric element can easily be modified/adjusted by adapting the spatial conformation of the receiving elements and the hardness of the toric element.
  • the receiving elements also allow the toric element to be kept taut to ensure this prestressing.
  • the prestress generated by the at least one inflection is organized so that the toric element exerts a restoring force on the control button, by elastic effect of the toric element at the level of said at least one inflection, said restoring force tending to return each support zone to its stable inactive position.
  • the prestressing mentioned above locally generates a restoring force at each inflection.
  • the sum of the restoring forces applied by the different planned inflections results in the restoring force mentioned above. It may be advantageous to provide for the presence of such a restoring force at least at each support zone.
  • the stiffness of the return mechanism at each location on the periphery of the toric element can easily be modified and adapted by adapting the number, positioning, and height of the at least one first rib and the at least one second rib.
  • the receiving elements may comprise, at each support zone, two first ribs arranged on either side of a second rib. This has the advantage of providing a return function in a very simple manner, by the sole effect of the elastic return of the toric element previously prestressed at the time of its installation in the receiving elements.
  • the receiving elements may be provided to impose a first inflection associated with each support zone, the first inflection being arranged directly above the associated support zone. In this way, it is easy to ensure that the straight line along which the restoring force obtained by the presence of the inflection extends is positioned at the right angle to the support zone concerned, allowing good control of the intensity of this restoring force.
  • the receiving elements are configured so as to impose at least one second inflection positioned offset from said support zone along the circumference of the toric element.
  • This second inflection zone also generates a return force in at least one zone other than the support zones, this making it possible to provide a movement capability for moving the control button following a movement other than that generated at the level of each support zone.
  • the base extends along a main plane and that the control button is superimposed on the base along a main axis generally oriented transversely to the main plane of the base, the toric element being placed between a wall upper part of the base and a lower wall of the control button following the main axis.
  • control button is movable in translation relative to the base along the main axis. It is in particular possible to manufacture in this way a control button in the form of a push button movable by simple translation relative to the base.
  • control button is pivotally movable relative to the base along at least one pivot axis oriented transversely to the main axis.
  • control button in the form of a rocker button movable by simple pivoting relative to the base.
  • control button comprises an annular ring, mechanically independent of the base, having said ability to move relative to the base and delimiting at least two support zones offset from each other on the peripheral periphery of the annular ring.
  • the control button can therefore then integrate two support zones, for example diametrically opposed, intended to actuate two separate switches themselves associated with the respective control of a first electrical function and a second electrical function distinct from each other.
  • the annular ring can be provided to be able to have an ability to perform a tilting movement around two points diametrically opposed to each other and each positioned between the two support zones and a possible additional ability to perform a translational movement making it possible to actuate these two switches simultaneously in order to selectively actuate a third electrical function.
  • the number of support zones can possibly be equal to 3, 4, or greater than or equal to 5 depending on the needs associated with the manual control device.
  • the manual control device further comprises an upper cover secured to the base and positioned in a central opening delimited by the annular ring.
  • This upper cover may optionally be fixed and have a simple trim function. Alternatively, it is possible for it to be movable in translation and/or in pivoting.
  • the cover may also have a second toric element conforming to the toric element described in relation to the control button, this second toric element having dimensions adapted to be, for example, inserted into the space delimited by an internal circumference of the toric element previously described.
  • the upper cover has a peripheral edge, is integral with the base by all or part of its peripheral edge, and has an ability to deform by bending during the manual application of a pressing force by the user of the manual control device on a central zone of the upper cover, said central zone varying between a stable inactive configuration in which the upper cover is not bent when said pressing force is absent and an unstable active configuration in which the upper cover is bent when said pressing force is applied, the manual control device comprising an additional switch arranged so that the central zone of the upper cover places the additional switch in the inactive state when the central zone occupies the stable inactive configuration and places the additional switch in the active state when the central zone occupies the unstable active configuration.
  • the manual control device comprises stop elements against which the control button bears when the control button adopts a spatial positioning relative to the base in which each support zone occupies its stable inactive position under the effect of the toric element, the stop elements being directly or indirectly secured to the base.
  • the manual control device 10 firstly comprises a base 11.

  • the control button 12 delimits at least one support zone (i.e. one support zone or several support zones) accessible from outside the manual control device 10. Thus the number of support zones can be greater than or equal to 1. In the example illustrated, the control button 12 delimits two support zones 13a, 13b, which is not limiting.
  • Each support zone 13a, 13b allows the manual application of a support force by the user of the manual control device 10 on this support zone 13a, 13b.
  • This support force thus applied manually by the user causes a movement of the support zone 13a, 13b concerned from a stable inactive position to an unstable active position.
  • stable position is meant here that this so-called stable position is naturally and automatically occupied as long as no manual force is applied to the support area of the control button 12.
  • stable position By “unstable position”, however, is meant in this document that this so-called unstable position is only temporarily occupied as long as the manual force is applied to the support zone of the control button 12, this unstable position being automatically left as soon as the manual force decreases or ceases.
  • the manual control device 10 further comprises at least one switch capable of occupying an active state and an inactive state.
  • a given switch is associated with a given support zone 13a, 13b of the control button 12 and vice versa.

  • un bouton de commande monté sur le socle d'une manière offrant au moins une aptitude de mouvement par rapport au socle suivant au moins un degré de liberté par pivotement ou par translation, le bouton de commande délimitant au moins une zone d'appui accessible depuis l'extérieur du dispositif de commande manuelle, chaque zone d'appui permettant l'application manuelle d'un effort d'appui par l'utilisateur du dispositif de commande manuelle sur la zone d'appui, ledit effort d'appui entraînant un déplacement de la zone d'appui concernée d'une position inactive stable à une position active instable,
  • au moins un interrupteur susceptible d'occuper un état actif et un état inactif, un interrupteur étant associé à une zone d'appui du bouton de commande, la zone d'appui plaçant l'interrupteur associé dans l'état inactif lorsqu'elle occupe la position inactive stable et plaçant l'interrupteur associé dans l'état actif lorsqu'elle occupe la position active instable,
  • un mécanisme de rappel sollicitant le bouton de commande d'une manière tendant à ramener ladite au moins une zone d'appui vers la position inactive stable.
The present invention relates to a manual control device, the manual control device comprising:
  • a base,
  • a control button mounted on the base in a manner providing at least one ability to move relative to the base in at least one degree of freedom by pivoting or translation, the control button delimiting at least one support zone accessible from outside the manual control device, each support zone allowing the manual application of a support force by the user of the manual control device on the support zone, said support force causing a movement of the support zone concerned from a stable inactive position to an unstable active position,
  • at least one switch capable of occupying an active state and an inactive state, a switch being associated with a support zone of the control button, the support zone placing the associated switch in the inactive state when it occupies the stable inactive position and placing the associated switch in the active state when it occupies the unstable active position,

L'invention trouve une application notamment dans la fourniture d'un dispositif de commande manuelle à fixer sur une paroi murale ou se présentant sous la forme d'une télécommande, dont l'actionnement de chaque zone d'appui permet d'activer ou non, sélectivement, une fonction électrique prévue pour être ainsi commandée par simple appui sur la zone d'appui.The invention finds an application in particular in the provision of a manual control device to be fixed to a wall or in the form of a remote control, the actuation of each support zone of which makes it possible to activate or not, selectively, an electrical function intended to be thus controlled by simple pressure on the support zone.

Etat de la techniqueState of the art

Il existe déjà des dispositifs de commande manuelle du type précité. Le document US2014/311879A1 en est un exemple.There are already manual control devices of the above type. The document US2014/311879A1 is an example.

Le fait d'appuyer sur une zone d'appui donnée permet de faire passer l'interrupteur associé vers l'état actif, ce qui provoque la mise en œuvre de la fonction électrique associée à cet interrupteur, notamment par la fermeture d'un circuit électrique dont l'interrupteur fait partie intégrante. Le relâchement de la zone d'appui permet le retour de l'interrupteur vers son état inactif, et c'est la raison de l'existence du mécanisme de rappel susmentionné.Pressing a given support area allows the associated switch to move to the active state, which causes the implementation of the electrical function associated with this switch, in particular by closing an electrical circuit of which the switch is an integral part. Releasing the support area allows the switch to return to its inactive state, and this is the reason for the existence of the aforementioned return mechanism.

Classiquement, chaque zone d'appui est intégrée sur une touche commune ou sur une touche séparée permettant l'utilisation de grappes de touches indépendantes, ou permettant l'utilisation d'une ou plusieurs touches directement intégrées à la façade avant du dispositif de commande manuelle. Le mécanisme de rappel associé à une ou plusieurs de ces touches se présente typiquement sous la forme d'un ressort mécanique.Conventionally, each support zone is integrated on a common key or on a separate key allowing the use of independent key clusters, or allowing the use of one or more keys directly integrated into the front panel of the manual control device. The return mechanism associated with one or more of these keys is typically in the form of a mechanical spring.

Ces solutions sont certes efficaces, mais en contrepartie d'une grande complexité de conception et de fabrication, et impliquant également un coût de fabrication très élevé.These solutions are certainly effective, but come at the cost of great design and manufacturing complexity, and also involve very high manufacturing costs.

Dans ce contexte, il existe un besoin de disposer d'un dispositif de commande manuelle qui soit robuste, simple, efficace, économique, potentiellement facilement ajustable et modulable.In this context, there is a need for a manual control device that is robust, simple, efficient, economical, potentially easily adjustable and modular.

Objet de l'inventionSubject of the invention

La présente invention a pour but de proposer un dispositif de commande manuelle qui soit robuste, simple, efficace et économique et facilement modulable.The aim of the present invention is to provide a manual control device which is robust, simple, efficient and economical and easily modular.

Ce but peut être atteint grâce à la mise en œuvre d'un dispositif de commande manuelle, le dispositif de commande manuelle comprenant :

  • un socle,
  • un bouton de commande monté sur le socle d'une manière offrant au moins une aptitude de mouvement par rapport au socle suivant au moins un degré de liberté par pivotement ou par translation, le bouton de commande délimitant au moins une zone d'appui accessible depuis l'extérieur du dispositif de commande manuelle, chaque zone d'appui permettant l'application manuelle d'un effort d'appui par l'utilisateur du dispositif de commande manuelle sur la zone d'appui, ledit effort d'appui entraînant un déplacement de la zone d'appui concernée d'une position inactive stable à une position active instable,
  • au moins un interrupteur susceptible d'occuper un état actif et un état inactif, un interrupteur étant associé à une zone d'appui du bouton de commande, la zone d'appui plaçant l'interrupteur associé dans l'état inactif lorsqu'elle occupe la position inactive stable et plaçant l'interrupteur associé dans l'état actif lorsqu'elle occupe la position active instable,
  • un mécanisme de rappel sollicitant le bouton de commande d'une manière tendant à ramener ladite au moins une zone d'appui vers la position inactive stable,
dans lequel :
  • le mécanisme de rappel comprend un élément torique formé dans une matière élastique,
  • le dispositif de commande manuelle comprend des éléments de réception appartenant au bouton de commande et/ou au socle, les éléments de réception permettant de recevoir l'élément torique et d'assurer son maintien par rapport au bouton de commande et au socle,
  • les éléments de réception étant agencés de sorte à imposer localement à l'élément torique au moins une inflexion générant une précontrainte variable le long de la circonférence de l'élément torique.
This goal can be achieved by implementing a manual control device, the manual control device comprising:
  • a base,
  • a control button mounted on the base in a manner providing at least one ability to move relative to the base in at least one degree of freedom by pivoting or translation, the control button delimiting at least one support zone accessible from outside the manual control device, each support zone allowing the manual application of a support force by the user of the manual control device on the support zone, said support force causing a movement of the support zone concerned from a stable inactive position to an unstable active position,
  • at least one switch capable of occupying an active state and an inactive state, a switch being associated with a support zone of the control button, the support zone placing the associated switch in the inactive state when it occupies the stable inactive position and placing the associated switch in the active state when it occupies the unstable active position,
  • a return mechanism urging the control button in a manner tending to return said at least one support zone to the stable inactive position,
in which:
  • the return mechanism comprises a toric element formed from an elastic material,
  • the manual control device comprises receiving elements belonging to the control button and/or the base, the receiving elements making it possible to receive the toroidal element and to ensure its retention relative to the control button and the base,
  • the receiving elements being arranged so as to locally impose on the toric element at least one inflection generating a variable prestress along the circumference of the toric element.

Par ces dispositions, il est possible de créer géométriquement au moins une déviation/inflexion de l'élément torique apte à repousser une zone d'appui par un simple effet élastique de l'élément torique. Il en résulte que le mécanisme de rappel est très simple, efficace, économique, et facile à monter car il suffit de rapporter l'élément torique dans les éléments de réception. L'élément torique ainsi rapporté sur le socle et/ou sur le bouton de commande subit avantageusement une précontrainte locale au niveau de chaque inflexion prévue. Cette précontrainte se produit au moment du montage de l'élément torique et est ensuite présente en permanence tant que le dispositif de commande reste assemblé. Cette précontrainte résulte de la flexion locale de l'élément torique à chaque inflexion. De plus, le fait que l'élément torique travaille en flexion et non en compression, lui confère une bonne robustesse et une grande durabilité. Par la formation des inflexions, il est possible de maintenir le bouton de commande contre le socle ou le couvercle supérieur qui sera décrit plus loin, par un effort présentant une intensité variable en se déplaçant le long de la périphérie de l'élément torique, en fonction de la position des inflexions et leur forme (profondeur, longueur, présence d'une partie plate, valeur des inclinaisons des parties inclinées de l'inflexion etc), par exemple présentant une intensité, au niveau des emplacements autour desquels le bouton de commande est censé être déplacé, supérieure à l'intensité au niveau de chaque zone d'appui. Le maintien du bouton de commande en position stable contre le socle et/ou contre le couvercle supérieur se fait de manière simple, efficace et économique, grâce à la présence d'un simple élément torique. Cette solution est en effet très peu onéreuse grâce à l'utilisation d'un composant standard, facile à assembler avec de très bonnes caractéristiques d'élasticité et d'endurance. La raideur du mécanisme de rappel en chaque endroit de la périphérie de l'élément torique peut facilement être modifiée/ajustée par une adaptation de la conformation spatiale des éléments de réception et de la dureté de l'élément torique. Les éléments de réception permettent également de maintenir l'élément torique tendu pour garantir cette précontrainte.By these provisions, it is possible to geometrically create at least one deflection/inflection of the toric element capable of pushing back a support zone by a simple elastic effect of the toric element. As a result, the return mechanism is very simple, efficient, economical, and easy to assemble because it is sufficient to attach the toric element to the receiving elements. The toric element thus attached to the base and/or to the control button advantageously undergoes a local prestress at each intended inflection. This prestress occurs at the time of assembly of the toric element and is then present permanently as long as the control device remains assembled. This prestress results from the local bending of the toric element at each inflection. In addition, the fact that the toric element works in bending and not in compression, gives it good robustness and great durability. By forming the inflections, it is possible to hold the control button against the base or the upper cover which will be described later, by a force having a variable intensity by moving along the periphery of the toric element, depending on the position of the inflections and their shape (depth, length, presence of a flat part, value of the inclinations of the inclined parts of the inflection etc.), for example having an intensity, at the locations around which the control button is supposed to be moved, greater than the intensity at each support zone. Maintaining the control button in a stable position against the base and/or against the upper cover is done in a simple, effective and economical way, thanks to the presence of a simple toric element. This solution is in fact very inexpensive thanks to the use of a standard component, easy to assemble with very good elasticity and endurance characteristics. The stiffness of the return mechanism at each location on the periphery of the toric element can easily be modified/adjusted by adapting the spatial conformation of the receiving elements and the hardness of the toric element. The receiving elements also allow the toric element to be kept taut to ensure this prestressing.

Certains aspects préférés mais non limitatifs sont les suivants.Some preferred but not limiting aspects are as follows.

La précontrainte générée par l'au moins une inflexion est organisée de sorte que l'élément torique exerce sur le bouton de commande une force de rappel, par effet élastique de l'élément torique au niveau de ladite au moins une inflexion, ladite force de rappel tendant à un retour de chaque zone d'appui vers sa position inactive stable. On évite ainsi de faire travailler l'élément torique en compression (effet élastique en compression obtenu uniquement par le phénomène de pincement de l'élément torique entre le socle et le bouton de commande), travail pour lequel l'élément torique est mal dimensionné.The prestress generated by the at least one inflection is organized so that the toric element exerts a restoring force on the control button, by elastic effect of the toric element at the level of said at least one inflection, said restoring force tending to return each support zone to its stable inactive position. This avoids making the toric element work in compression (elastic effect in compression obtained solely by the phenomenon of pinching the toric element between the base and the control button), work for which the toric element is poorly dimensioned.

La précontrainte précédemment mentionnée génère localement un effort de rappel au niveau de chaque inflexion. La somme des efforts de rappel appliqués par les différentes inflexions prévues résulte en la force de rappel précédemment mentionnée. Il peut être avantageux de prévoir la présence d'un tel effort de rappel au moins au niveau de chaque zone d'appui.The prestressing mentioned above locally generates a restoring force at each inflection. The sum of the restoring forces applied by the different planned inflections results in the restoring force mentioned above. It may be advantageous to provide for the presence of such a restoring force at least at each support zone.

Les éléments de réception comprennent, pour la formation de chaque inflexion :

  • au moins une première nervure solidaire du socle, contre laquelle l'élément torique vient s'appuyer suivant un premier sens,
  • au moins une deuxième nervure solidaire du bouton de commande, contre laquelle l'élément torique vient s'appuyer suivant un deuxième sens opposé audit premier sens, la deuxième nervure étant décalée par rapport à la première nervure le long de la circonférence de l'élément torique.
The reception elements include, for the formation of each inflection:
  • at least one first rib secured to the base, against which the toric element rests in a first direction,
  • at least one second rib secured to the control button, against which the toric element bears in a second direction opposite to said first direction, the second rib being offset relative to the first rib along the circumference of the toric element.

La raideur du mécanisme de rappel en chaque endroit de la périphérie de l'élément torique peut facilement être modifiée et adaptée par une adaptation du nombre, du positionnement, et de la hauteur, de l'au moins une première nervure et de l'au moins une deuxième nervure.The stiffness of the return mechanism at each location on the periphery of the toric element can easily be modified and adapted by adapting the number, positioning, and height of the at least one first rib and the at least one second rib.

Les éléments de réception peuvent comprendre, au niveau de chaque zone d'appui, deux premières nervures disposées de part et d'autre d'une deuxième nervure. Cela a pour avantage de conférer une fonction de rappel de manière très simple, par le seul effet du retour élastique de l'élément torique précédemment précontraint au moment de sa mise en place dans les éléments de réception.The receiving elements may comprise, at each support zone, two first ribs arranged on either side of a second rib. This has the advantage of providing a return function in a very simple manner, by the sole effect of the elastic return of the toric element previously prestressed at the time of its installation in the receiving elements.

Les éléments de réception peuvent être prévus pour imposer une première inflexion associée à chaque zone d'appui, la première inflexion étant agencée à l'aplomb de la zone d'appui associée. De la sorte, il est facile d'obtenir que la droite suivant laquelle s'étend l'effort de rappel obtenu par la présence de l'inflexion soit positionnée au droit de la zone d'appui concernée, permettant un bon contrôle de l'intensité de cet effort de rappel.The receiving elements may be provided to impose a first inflection associated with each support zone, the first inflection being arranged directly above the associated support zone. In this way, it is easy to ensure that the straight line along which the restoring force obtained by the presence of the inflection extends is positioned at the right angle to the support zone concerned, allowing good control of the intensity of this restoring force.

Selon un mode de réalisation, les éléments de réception sont configurés de sorte à imposer au moins une deuxième inflexion positionnée de manière décalée par rapport à ladite zone d'appui le long de la circonférence de l'élément torique.According to one embodiment, the receiving elements are configured so as to impose at least one second inflection positioned offset from said support zone along the circumference of the toric element.

Cette deuxième zone d'inflexion génère également un effort de rappel dans au moins une zone autre que les zones d'appui, ceci permettant d'offrir une aptitude de mouvement de déplacement du bouton de commande suivant un mouvement autre que celui généré au niveau de chaque zone d'appui.This second inflection zone also generates a return force in at least one zone other than the support zones, this making it possible to provide a movement capability for moving the control button following a movement other than that generated at the level of each support zone.

Il est possible de prévoir que le socle s'étende suivant un plan principal et que le bouton de commande soit superposé au socle suivant un axe principal globalement orienté transversalement au plan principal du socle, l'élément torique étant placé entre une paroi supérieure du socle et une paroi inférieure du bouton de commande suivant l'axe principal. Ces dispositions garantissent un montage particulièrement aisé.It is possible to provide that the base extends along a main plane and that the control button is superimposed on the base along a main axis generally oriented transversely to the main plane of the base, the toric element being placed between a wall upper part of the base and a lower wall of the control button following the main axis. These arrangements guarantee particularly easy assembly.

Selon un mode de réalisation, le bouton de commande est mobile en translation par rapport au socle le long de l'axe principal. Il est notamment possible de fabriquer de cette manière un bouton de commande se présentant sous la forme d'un bouton poussoir mobile par simple translation par rapport au socle.According to one embodiment, the control button is movable in translation relative to the base along the main axis. It is in particular possible to manufacture in this way a control button in the form of a push button movable by simple translation relative to the base.

De manière combinée ou alternative au mouvement de translation du bouton de commande, il peut être prévu que le bouton de commande soit mobile en pivotement par rapport au socle suivant au moins un axe de pivotement orienté transversalement à l'axe principal. Il est notamment possible de fabriquer de cette manière un bouton de commande se présentant sous la forme d'un bouton basculant mobile par simple pivotement par rapport au socle. Ces différentes variantes sont très faciles à obtenir, de manière économique et durable de surcroît, par une simple adaptation des inflexions générées le long de la périphérie de l'élément torique par les éléments de réception.In combination with or as an alternative to the translational movement of the control button, it may be provided that the control button is pivotally movable relative to the base along at least one pivot axis oriented transversely to the main axis. In particular, it is possible to manufacture in this way a control button in the form of a rocker button movable by simple pivoting relative to the base. These different variants are very easy to obtain, economically and sustainably, by simply adapting the inflections generated along the periphery of the toric element by the receiving elements.

Selon un autre mode de réalisation, le bouton de commande comprend une bague annulaire, mécaniquement indépendante du socle, présentant ladite aptitude de mouvement par rapport au socle et délimitant au moins deux zones d'appui décalées entre elles sur le pourtour périphérique de la bague annulaire. Le bouton de commande peut donc alors intégrer deux zones d'appui par exemple diamétralement opposées, destinées à actionner deux interrupteurs distincts eux-mêmes associés au pilotage respectif d'une première fonction électrique et d'une deuxième fonction électrique distinctes l'une de l'autre. En fonction de l'organisation des éléments de réception, la bague annulaire peut être prévue pour pouvoir avoir une aptitude d'un mouvement de basculement autour de deux points diamétralement opposés entre eux et chacun positionné entre les deux zones d'appui et une éventuelle aptitude supplémentaire de mouvement de translation permettant d'actionner ces deux interrupteurs simultanément afin d'actionner sélectivement une troisième fonction électrique. Il est à noter que le nombre de zones d'appui peut éventuellement être égal à 3, à 4, ou supérieur ou égal à 5 en fonction des besoins associés au dispositif de commande manuelle.According to another embodiment, the control button comprises an annular ring, mechanically independent of the base, having said ability to move relative to the base and delimiting at least two support zones offset from each other on the peripheral periphery of the annular ring. The control button can therefore then integrate two support zones, for example diametrically opposed, intended to actuate two separate switches themselves associated with the respective control of a first electrical function and a second electrical function distinct from each other. Depending on the organization of the receiving elements, the annular ring can be provided to be able to have an ability to perform a tilting movement around two points diametrically opposed to each other and each positioned between the two support zones and a possible additional ability to perform a translational movement making it possible to actuate these two switches simultaneously in order to selectively actuate a third electrical function. It should be noted that the number of support zones can possibly be equal to 3, 4, or greater than or equal to 5 depending on the needs associated with the manual control device.

Selon un mode de réalisation non limitatif, le dispositif de commande manuelle comprend en outre un couvercle supérieur solidaire du socle et positionné dans une ouverture centrale délimitée par la bague annulaire. Ce couvercle supérieur peut éventuellement être fixe et présenter une simple fonction d'enjoliveur. Alternativement, il est possible qu'il soit mobile en translation et/ou en pivotement. En particulier, le couvercle peut disposer également d'un deuxième élément torique conforme à l'élément torique décrit en relation avec le bouton de commande, ce deuxième élément torique ayant des dimensions adaptées pour par exemple être inséré dans l'espace délimité par une circonférence interne de l'élément torique précédemment décrit.According to a non-limiting embodiment, the manual control device further comprises an upper cover secured to the base and positioned in a central opening delimited by the annular ring. This upper cover may optionally be fixed and have a simple trim function. Alternatively, it is possible for it to be movable in translation and/or in pivoting. In particular, the cover may also have a second toric element conforming to the toric element described in relation to the control button, this second toric element having dimensions adapted to be, for example, inserted into the space delimited by an internal circumference of the toric element previously described.

Dans un mode de réalisation particulier et alternatif, le couvercle supérieur présente un bord périphérique, est solidaire du socle par tout ou partie de son bord périphérique, et présente une aptitude à se déformer par flexion lors de l'application manuelle d'une force d'appui par l'utilisateur du dispositif de commande manuelle sur une zone centrale du couvercle supérieur, ladite zone centrale variant entre une configuration inactive stable dans laquelle le couvercle supérieur est non fléchi lorsque ladite force d'appui est absente et une configuration active instable dans lequel le couvercle supérieur est fléchi lorsque ladite force d'appui est appliquée, le dispositif de commande manuelle comprenant un interrupteur supplémentaire agencé de sorte que la zone centrale du couvercle supérieur place l'interrupteur supplémentaire dans l'état inactif lorsque la zone centrale occupe la configuration inactive stable et place l'interrupteur supplémentaire dans l'état actif lorsque la zone centrale occupe la configuration active instable.In a particular and alternative embodiment, the upper cover has a peripheral edge, is integral with the base by all or part of its peripheral edge, and has an ability to deform by bending during the manual application of a pressing force by the user of the manual control device on a central zone of the upper cover, said central zone varying between a stable inactive configuration in which the upper cover is not bent when said pressing force is absent and an unstable active configuration in which the upper cover is bent when said pressing force is applied, the manual control device comprising an additional switch arranged so that the central zone of the upper cover places the additional switch in the inactive state when the central zone occupies the stable inactive configuration and places the additional switch in the active state when the central zone occupies the unstable active configuration.

Selon un mode de réalisation non limitatif, le dispositif de commande manuelle comprend des éléments de butée contre lesquels le bouton de commande est en appui lorsque le bouton de commande adopte un positionnement spatial par rapport au socle dans lequel chaque zone d'appui occupe sa position inactive stable sous l'effet de l'élément torique, les éléments de butée étant directement ou indirectement solidaires du socle.According to a non-limiting embodiment, the manual control device comprises stop elements against which the control button bears when the control button adopts a spatial positioning relative to the base in which each support zone occupies its stable inactive position under the effect of the toric element, the stop elements being directly or indirectly secured to the base.

Dans tout ce qui précède, les fonctions électriques et tout ou partie des interrupteurs évoqués précédemment sont possiblement supportés par un circuit imprimé comprenant les composants électriques et conducteurs idoines intégrés dans une structure mécanique. Ce circuit imprimé est notamment rapporté sur le socle.In all of the above, the electrical functions and all or part of the switches mentioned above are possibly supported by a printed circuit comprising the appropriate electrical and conductive components integrated into a mechanical structure. This printed circuit is notably attached to the base.

Description détailléeDetailed description

Sur les Figures 1 à 9 et dans la suite de la description, les mêmes références représentent les éléments identiques ou similaires. De plus, les différents éléments ne sont pas obligatoirement représentés à l'échelle de manière à privilégier la clarté des figures. Par ailleurs, les différents modes de réalisation et variantes ne sont pas exclusifs les uns des autres et peuvent être combinés entre eux.On the Figures 1 to 9 and in the remainder of the description, the same references represent identical or similar elements. Furthermore, the different elements are not necessarily represented to scale so as to favor the clarity of the figures. Furthermore, the different embodiments and variants are not mutually exclusive and can be combined with each other.

Sur les Figures 1 à 9, il est représenté un exemple de dispositif de commande manuelle 10 selon l'invention.On the Figures 1 to 9 , an example of a manual control device 10 according to the invention is shown.

Le dispositif de commande manuelle 10 comprend d'abord un socle 11. Le socle 11 est notamment apte à être tenu par la main d'un utilisateur du dispositif de commande manuelle 10 et/ou à être fixé à une paroi fixe. Sa forme et son encombrement ne sont pas limitatifs en soi. Par simplicité dans le cadre de la présente invention, le dispositif de commande manuelle 10 présente une forme extérieure globalement circulaire. Toutefois, une autre forme (ovale, carrée ou autre) est tout à fait envisageable.The manual control device 10 firstly comprises a base 11. The base 11 is in particular capable of being held by the hand of a user of the manual control device 10 and/or of being fixed to a fixed wall. Its shape and its size are not limiting in themselves. For simplicity within the scope of the present invention, the manual control device 10 has a generally circular external shape. However, another shape (oval, square or other) is entirely conceivable.

Le dispositif de commande manuelle 10 comprend aussi un bouton de commande 12 monté sur le socle 11 d'une manière offrant au moins une aptitude de mouvement par rapport au socle 11 suivant au moins un degré de liberté par pivotement et/ou par translation. En pratique, le bouton de commande 12 peut en particulier correspondre à un capot de commande dans le sens où il complète en partie le socle 11.The manual control device 10 also comprises a control button 12 mounted on the base 11 in a manner providing at least one ability to move relative to the base 11 in at least one degree of freedom by pivoting and/or by translation. In practice, the control button 12 may in particular correspond to a control cover in the sense that it partially completes the base 11.

Le bouton de commande 12 délimite au moins une zone d'appui (c'est-à-dire une zone d'appui ou plusieurs zones d'appui) accessible depuis l'extérieur du dispositif de commande manuelle 10. Ainsi le nombre de zone d'appui peut être supérieur ou égal à 1. Dans l'exemple illustré, le bouton de commande 12 délimite deux zones d'appui 13a, 13b, ce qui n'est pas limitatif.The control button 12 delimits at least one support zone (i.e. one support zone or several support zones) accessible from outside the manual control device 10. Thus the number of support zones can be greater than or equal to 1. In the example illustrated, the control button 12 delimits two support zones 13a, 13b, which is not limiting.

Chaque zone d'appui 13a, 13b permet l'application manuelle d'un effort d'appui par l'utilisateur du dispositif de commande manuelle 10 sur cette zone d'appui 13a, 13b. Cet effort d'appui ainsi appliqué manuellement par l'utilisateur entraîne un déplacement de la zone d'appui 13a, 13b concernée d'une position inactive stable à une position active instable.Each support zone 13a, 13b allows the manual application of a support force by the user of the manual control device 10 on this support zone 13a, 13b. This support force thus applied manually by the user causes a movement of the support zone 13a, 13b concerned from a stable inactive position to an unstable active position.

Par « position stable », on entend ici que cette position dite stable est naturellement et automatiquement occupée tant qu'aucun effort manuel n'est appliqué sur la zone d'appui du bouton de commande 12.By “stable position” is meant here that this so-called stable position is naturally and automatically occupied as long as no manual force is applied to the support area of the control button 12.

Par « position instable », on entend dans ce document, par contre, que cette position dite instable n'est temporairement occupée que tant que l'effort manuel est appliqué sur la zone d'appui du bouton de commande 12, cette position instable étant automatiquement quittée dès que l'effort manuel diminue ou cesse.By "unstable position", however, is meant in this document that this so-called unstable position is only temporarily occupied as long as the manual force is applied to the support zone of the control button 12, this unstable position being automatically left as soon as the manual force decreases or ceases.

Le dispositif de commande manuelle 10 comprend en outre au moins un interrupteur susceptible d'occuper un état actif et un état inactif. Un interrupteur donné est associé à une zone d'appui 13a, 13b donnée du bouton de commande 12 et réciproquement. Le nombre d'interrupteur est donc identique au nombre de zones d'appui. En conséquence, l'exemple de dispositif de commande manuelle 10 représenté ici à titre non limitatif comprend deux interrupteurs 14a, 14b distincts. L'au moins un interrupteur peut en particulier être logé dans le socle 11, même si cela n'est pas limitatif.The manual control device 10 further comprises at least one switch capable of occupying an active state and an inactive state. A given switch is associated with a given support zone 13a, 13b of the control button 12 and vice versa. The number of switches is therefore identical to the number of support zones. Consequently, the example of a manual control device 10 shown here without limitation comprises two separate switches 14a, 14b. The at least one switch may in particular be housed in the base 11, even if this is not limiting.

Chaque interrupteur 14a, 14b est dédié à un actionnement d'au moins une fonction électrique. Notamment l'état actif de l'interrupteur 14a, 14b correspond à l'actionnement d'une première fonction électrique et l'état inactif correspond soit à l'interruption de l'actionnement de la première fonction électrique, soit à l'actionnement d'une deuxième fonction électrique.Each switch 14a, 14b is dedicated to actuation of at least one electrical function. In particular, the active state of the switch 14a, 14b corresponds to the actuation of a first electrical function and the inactive state corresponds either to the interruption of the actuation of the first electrical function, or to the actuation of a second electrical function.

Les fonctions électriques et tout ou partie des interrupteurs sont possiblement supportées par un circuit imprimé 15 comprenant les composants électroniques et conducteurs idoines intégrés dans une structure mécanique. Ce circuit imprimé est notamment rapporté sur le socle 11. Ce circuit imprimé 15 est alimenté en énergie par une pile 16 montée sur le socle 11 ou sur le circuit imprimé. Il peut également être prévu des éléments de communication de type antenne, radio, wifi, Bluetooth, ou tout autre protocole de communication sans fil adapté.The electrical functions and all or part of the switches are possibly supported by a printed circuit 15 comprising the appropriate electronic components and conductors integrated into a mechanical structure. This printed circuit is in particular attached to the base 11. This printed circuit 15 is powered by a battery 16 mounted on the base 11 or on the printed circuit. Communication elements such as antenna, radio, Wi-Fi, Bluetooth, or any other suitable wireless communication protocol may also be provided.

La zone d'appui 13a, 13b permet de placer l'interrupteur 14a, 14b associé dans l'état inactif lorsqu'elle occupe la position inactive stable et permet de placer l'interrupteur 14a, 14b associé dans l'état actif lorsqu'elle occupe la position active instable.The support zone 13a, 13b makes it possible to place the associated switch 14a, 14b in the inactive state when it occupies the stable inactive position and makes it possible to place the associated switch 14a, 14b in the active state when it occupies the unstable active position.

La nature des interrupteurs n'est pas limitative en soi. Par ailleurs, le bouton de commande 12 peut comprendre des tenons d'actionnement 17a, 17b permettant de venir appuyer sur l'interrupteur 14a, 14b associé.The nature of the switches is not limiting in itself. Furthermore, the control button 12 may include actuating pins 17a, 17b allowing the associated switch 14a, 14b to be pressed.

Le dispositif de commande manuelle 10 comprend également un mécanisme de rappel sollicitant le bouton de commande 12 d'une manière tendant à ramener chaque zone d'appui 13a, 13b vers sa position inactive stable.The manual control device 10 also comprises a return mechanism urging the control button 12 in a manner tending to return each support zone 13a, 13b to its stable inactive position.

Comme cela est représenté sur les Figures 3 à 9, le mécanisme de rappel comprend très avantageusement un élément torique 18 formé dans une matière élastique, ayant au repos la forme d'un tore, dont la section de coupe peut être circulaire, oblongue, rectangulaire, ou toute autre forme. L'élément torique 18 peut notamment être une pièce indépendante du socle 11 et du bouton de commande 12, et en particulier être interposé entre le socle 11 et le bouton de commande 12.As shown on the Figures 3 to 9 , the return mechanism very advantageously comprises a toric element 18 formed from an elastic material, having at rest the shape of a torus, the cross-section of which may be circular, oblong, rectangular, or any other shape. The toric element 18 may in particular be a part independent of the base 11 and the control button 12, and in particular be interposed between the base 11 and the control button 12.

Comme cela est décrit en détail plus loin, le dispositif de commande manuelle 10 comprend des éléments de réception 19 appartenant au bouton de commande 12 et/ou au socle 11, les éléments de réception 19 permettant de recevoir l'élément torique 18 et d'assurer son maintien par rapport au bouton de commande 12 et au socle 11.As described in detail below, the manual control device 10 comprises receiving elements 19 belonging to the control button 12 and/or to the base 11, the receiving elements 19 making it possible to receive the toroidal element 18 and to ensure its retention relative to the control button 12 and to the base 11.

Essentiellement, les éléments de réception 19 sont agencés de sorte à imposer localement à l'élément torique 18 au moins une inflexion 20 générant une précontrainte variable le long de la circonférence de l'élément torique 18. Cette inflexion 20 est réalisée dans une direction sensiblement perpendiculaire à un plan principal P du socle 11. D'autres contraintes peuvent également être prévues sur l'élément torique 18 dans une direction parallèle au plan principal P du socle 11, par exemple pour conformer l'élément torique 18 à la forme du socle 11, notamment si celui-ci n'est pas circulaire.Essentially, the receiving elements 19 are arranged so as to locally impose on the toric element 18 at least one inflection 20 generating a variable prestress along the circumference of the toric element 18. This inflection 20 is produced in a direction substantially perpendicular to a main plane P of the base 11. Other constraints may also be provided on the toric element 18 in a direction parallel to the main plane P of the base 11, for example to conform the toric element 18 to the shape of the base 11, in particular if the latter is not circular.

La précontrainte générée par l'au moins une inflexion 20 est organisée de sorte que l'élément torique 18 exerce sur le bouton de commande 12 une force de rappel FT, par effet élastique de l'élément torique 18 au niveau de ladite au moins une inflexion 20, ladite force de rappel FT tendant à un retour de chaque zone d'appui 13a, 13b vers sa position inactive stable.The prestress generated by the at least one inflection 20 is organized so that the toric element 18 exerts a return force FT on the control button 12, by elastic effect of the toric element 18 at the level of said at least one inflection 20, said return force FT tending to a return of each support zone 13a, 13b towards its stable inactive position.

Selon la forme extérieure du dispositif de commande manuelle 10, d'autres éléments de maintien de l'élément torique 18 peuvent être prévus pour son maintien dans le plan principal P et pour lui donner la déformée souhaitée dans ce plan, notamment au niveau des inflexions 20. Ces éléments de maintien assurent notamment une tension de l'élément torique 18 dans le plan principal P.Depending on the external shape of the manual control device 10, other elements for holding the toric element 18 may be provided to hold it in the main plane P and to give it the desired deformation in this plane, in particular at the level of the inflections 20. These holding elements in particular ensure tension of the toric element 18 in the main plane P.

Selon un mode de réalisation particulier, les éléments de réception 19 comprennent, pour la formation de chaque inflexion 20 :

  • au moins une première nervure 19a, dite nervure inférieure, solidaire du socle 11, contre laquelle l'élément torique 18 vient s'appuyer suivant un premier sens S1,
  • au moins une deuxième nervure 19b, dite nervure supérieure, solidaire du bouton de commande 12, contre laquelle l'élément torique 18 vient s'appuyer suivant un deuxième sens S2 opposé au premier sens S1, la deuxième nervure 19b étant décalée par rapport à la première nervure 19a le long de la circonférence de l'élément torique 18.
According to a particular embodiment, the receiving elements 19 comprise, for the formation of each inflection 20:
  • at least one first rib 19a, called the lower rib, secured to the base 11, against which the toric element 18 comes to bear in a first direction S1,
  • at least one second rib 19b, called the upper rib, integral with the control button 12, against which the toric element 18 comes to bear in a second direction S2 opposite to the first direction S1, the second rib 19b being offset relative to the first rib 19a along the circumference of the toric element 18.

L'effort appliqué par chaque première nervure 19a est noté F1 tandis que l'effort appliqué par chaque deuxième nervure 19b est noté F2.The force applied by each first rib 19a is noted F1 while the force applied by each second rib 19b is noted F2.

Avantageusement, la première et/ou la deuxième nervure 19a, 19b comprennent une zone de maintien 28 de l'élément torique 18 par rapport au socle 11 ou au bouton de commande 12. Dans l'exemple illustré à la figure 8, cette zone de maintien 28 présente une forme en U, de sorte à former un pont chevauchant une section de l'élément torique 18, maintenant ainsi l'élément torique 18 en position par rapport au bouton de commande 12. La deuxième nervure 19b servant d'appui contre l'élément torique 18 dans le deuxième sens S2 est notamment réalisée sur l'intérieur de la zone de maintien 28, en particulier sur le fond du pont ou de la forme en U. Les nervures 19a solidaires du socle 11 et illustrées sur la figures 8 forment ici uniquement des surfaces d'appui pour l'élément torique 18, mais elles pourraient également comprendre (de manière non représentée) des zones de maintien similaires aux zones de maintien 28 solidaires du bouton de commande 12. Alternativement, ce sont uniquement les nervures 19a qui pourraient comprendre des zones de maintien de l'élément torique 18.Advantageously, the first and/or the second rib 19a, 19b comprise a holding zone 28 of the toric element 18 relative to the base 11 or to the control button 12. In the example illustrated in figure 8 , this holding zone 28 has a U shape, so as to form a bridge overlapping a section of the toric element 18, thus holding the toric element 18 in position relative to the control button 12. The second rib 19b serving as a support against the toric element 18 in the second direction S2 is in particular produced on the inside of the holding zone 28, in particular on the bottom of the bridge or of the U shape. The ribs 19a secured to the base 11 and illustrated on the figures 8 here only form support surfaces for the toric element 18, but they could also comprise (in a manner not shown) holding zones similar to the holding zones 28 secured to the control button 12. Alternatively, it is only the ribs 19a which could comprise holding zones for the toric element 18.

L'extrémité libre de la zone de maintien 28 définit un élément de butée 27 servant à s'opposer à un rapprochement du bouton de commande 12 vers le socle 11 au-delà d'une certaine distance. Ces éléments de butée 27 servent notamment à limiter les déplacements relatifs entre le bouton de commande 12 et le socle 11, contre lesquels le bouton de commande 12 est en appui lorsque le bouton de commande 12 adopte un positionnement spatial par rapport au socle 11 dans lequel au moins une zone d'appui 13a, 13b occupe sa position active instable sous l'effet de l'effort manuel sur cette zone d'appui. Aussi comme visible à la figure 9, les nervures 19a représentées définissent par le biais d'une des pattes du pont un tel élément de butée. La patte dite centrale, positionnée au plus près du centre du dispositif de commande est notamment mise en contact avec une partie du socle au moins lors de l'appui sur la zone d'appui correspondante. En complément, ceci forme un point de pivot autour duquel le bouton de commande 12 peut basculer.The free end of the holding zone 28 defines a stop element 27 serving to oppose a movement of the control button 12 towards the base 11 beyond a certain distance. These stop elements 27 serve in particular to limit the relative movements between the control button 12 and the base 11, against which the control button 12 is supported when the control button 12 adopts a spatial positioning relative to the base 11 in which at least one support zone 13a, 13b occupies its unstable active position under the effect of the manual force on this support zone. Also as visible in the figure 9 , the ribs 19a shown define by means of one of the legs of the bridge such a stop element. The so-called central leg, positioned as close as possible to the center of the control device, is in particular brought into contact with a part of the base at least when pressing on the corresponding support zone. In addition, this forms a pivot point around which the control button 12 can tilt.

Ces zones de maintien prévues sur les nervures 19a, 19b participent également au maintien de l'élément torique 18 dans le plan principal P. Alternativement ou de manière complémentaire, d'autres éléments de maintien (non représentés) peuvent être prévus pour assurer les déformations nécessaires de l'élément torique 18 dans le plan principal P.These holding zones provided on the ribs 19a, 19b also participate in holding the toric element 18 in the main plane P. Alternatively or in a complementary manner, other holding elements (not shown) can be provided to ensure the necessary deformations of the toric element 18 in the main plane P.

La précontrainte précédemment mentionnée génère localement un effort de rappel au niveau de chaque inflexion 20. Cet effort de rappel au niveau d'une inflexion 20 donnée correspond sensiblement à l'opposé de la somme des efforts F1 et F2 appliqués par les nervures 19a, 19b agencées localement pour générer cette inflexion 20. La somme des efforts de rappel appliqués par les différentes inflexions 20 prévues résulte en la force de rappel FT précédemment mentionnée. Il peut être avantageux de prévoir la présence d'un tel effort de rappel au moins au niveau de chaque interrupteur 14a, 14b qui est destiné à être actionné par une zone d'appui 13a, 13b prévue.The previously mentioned prestressing locally generates a restoring force at the level of each inflection 20. This restoring force at the level of a given inflection 20 corresponds substantially to the opposite of the sum of the forces F1 and F2 applied by the ribs 19a, 19b arranged locally to generate this inflection 20. The sum of the return forces applied by the different inflections 20 provided results in the previously mentioned return force FT. It may be advantageous to provide the presence of such a return force at least at the level of each switch 14a, 14b which is intended to be actuated by a provided support zone 13a, 13b.

La raideur du mécanisme de rappel en chaque endroit de la périphérie de l'élément torique 18 peut facilement être modifiée et adaptée par une adaptation du nombre, du positionnement de chaque première nervure 19a et de chaque deuxième nervure 19b, et de la hauteur de la partie de chaque première nervure 19a et de chaque deuxième nervure 19b agissant selon un sens S1 ou S2 sur l'élément torique 18. Il est aussi envisageable un système réglable mécaniquement sans changement de la hauteur des nervures 19a, 19b ou de la dureté de l'élément torique 18, par exemple par le biais d'une ou plusieurs vis qui contraindraient plus ou moins l'élément torique 18 en un point donné de sa périphérie dans un sens S1 ou S2 sensiblement perpendiculaire au plan principal P du socle 11 (permettant in fine d'agir plus ou moins sur la longueur de l'élément torique 18 par effet de traction). Il peut aussi être envisagé de prévoir des cales fixées par exemple par collage et qui seraient adaptables. La raideur du mécanisme de rappel peut aussi être modifiée en jouant sur la dureté de l'élément torique 18 lui-même.The stiffness of the return mechanism at each location on the periphery of the toric element 18 can easily be modified and adapted by adapting the number and positioning of each first rib 19a and each second rib 19b, and the height of the portion of each first rib 19a and each second rib 19b acting in a direction S1 or S2 on the toric element 18. It is also possible to envisage a mechanically adjustable system without changing the height of the ribs 19a, 19b or the hardness of the toric element 18, for example by means of one or more screws which would constrain the toric element 18 more or less at a given point on its periphery in a direction S1 or S2 substantially perpendicular to the main plane P of the base 11 (ultimately making it possible to act more or less on the length of the toric element 18 by traction effect). It may also be considered to provide shims fixed for example by gluing and which would be adaptable. The stiffness of the return mechanism can also be modified by adjusting the hardness of the toric element 18 itself.

Selon un mode de réalisation particulier, les éléments de réception 19 comprennent, au niveau de chaque zone d'appui 13a, 13b, deux premières nervures 19a disposées de part et d'autre d'une deuxième nervure 19b unique. Ces dispositions sont par exemple visibles sur la Figure 8. Alternativement, de manière non représentée, il est possible de prévoir que les éléments de réception 19 comprennent, au niveau de chaque zone d'appui 13a, 13b, deux deuxièmes nervures 19b disposées de part et d'autre d'une première nervure 19a qui serait unique. Il peut aussi être possible de prévoir la présence, pour la formation de chaque inflexion 20, de deux premières nervures 19a et de deux deuxièmes nervures 19b. Toutes les variantes prévues ici ont pour avantage de conférer une fonction de rappel de manière très simple, par le seul effet du retour élastique de l'élément torique 18 précédemment précontraint au moment de sa mise en place dans les éléments de réception 19.According to a particular embodiment, the receiving elements 19 comprise, at the level of each support zone 13a, 13b, two first ribs 19a arranged on either side of a single second rib 19b. These arrangements are for example visible on the Figure 8 . Alternatively, in a manner not shown, it is possible to provide that the receiving elements 19 comprise, at each support zone 13a, 13b, two second ribs 19b arranged on either side of a first rib 19a which would be unique. It may also be possible to provide the presence, for the formation of each inflection 20, of two first ribs 19a and two second ribs 19b. All the variants provided here have the advantage of conferring a return function in a very simple manner, by the sole effect of the elastic return of the toric element 18 previously prestressed at the time of its placement in the receiving elements 19.

Selon un mode de réalisation, les éléments de réception 19 sont configurés pour imposer une première inflexion 20 associée à chaque zone d'appui 13a, 13b, la première inflexion 20A étant agencée à l'aplomb de la zone d'appui 13a ,13b associée. De la sorte, il est facile d'obtenir que le support de l'effort de rappel obtenu par la présence de l'inflexion soit positionné au droit de la zone d'appui 13a, 13b concernée, permettant un bon contrôle de l'intensité de cet effort de rappel.According to one embodiment, the receiving elements 19 are configured to impose a first inflection 20 associated with each support zone 13a, 13b, the first inflection 20A being arranged in line with the associated support zone 13a, 13b. In this way, it is easy to ensure that the support of the return force obtained by the presence of the inflection is positioned in line with the support zone 13a, 13b concerned, allowing good control of the intensity of this return force.

Selon un mode de réalisation, les éléments de réception 19 sont configurés de sorte à imposer au moins une deuxième inflexion 20B positionnée de manière décalée par rapport à ladite zone d'appui 13a, 13b le long de la circonférence de l'élément torique 18. Cette disposition permet de générer également un effort de rappel dans au moins une zone autre que les zones d'appui, ceci permettant d'offrir une aptitude de mouvement de déplacement du bouton de commande suivant un mouvement autre que celui généré au niveau de chaque zone d'appui.According to one embodiment, the receiving elements 19 are configured so as to impose at least one second inflection 20B positioned offset relative to said support zone 13a, 13b along the circumference of the toric element 18. This arrangement also makes it possible to generate a return force in at least one zone other than the support zones, this making it possible to offer a movement capability of moving the control button following a movement other than that generated at each support zone.

Dans la variante illustrée, il est prévu pour chaque zone d'appui 13a, 13b, la présence de deux deuxièmes inflexions 20B disposées de part et d'autre d'une unique première inflexion 20A elle-même située à l'aplomb de cette zone d'appui 13a, 13b. Chaque première inflexion 20A présente une longueur (comptée le long de l'élément torique 18) supérieure à la longueur de chaque deuxième inflexion 20B, ce qui garantit que la première inflexion 20A présente une plus grande souplesse, garantissant que l'effort manuel à appliquer sur la zone d'appui soit le plus adapté possible, selon une loi course/effort de la bague annulaire 21. Les deuxièmes inflexions 20B peuvent être prévues plus rigides. Elles permettent notamment de prévoir un mouvement d'appui simultané sur deux zones d'appui opposées, générant un mouvement de translation du bouton de commande 12 perpendiculairement au plan principal P, suivant l'axe principal D1. Ces deuxièmes inflexions 20B sont facultatives dans le cas où une translation selon D1 n'est pas recherchée.In the illustrated variant, for each support zone 13a, 13b, there is provided the presence of two second inflections 20B arranged on either side of a single first inflection 20A itself located directly above this support zone 13a, 13b. Each first inflection 20A has a length (counted along the toric element 18) greater than the length of each second inflection 20B, which guarantees that the first inflection 20A has greater flexibility, guaranteeing that the manual force to be applied to the support zone is as adapted as possible, according to a stroke/force law of the annular ring 21. The second inflections 20B can be provided to be more rigid. They make it possible in particular to provide a simultaneous support movement on two opposite support zones, generating a translation movement of the control button 12 perpendicular to the main plane P, along the main axis D1. These second inflections 20B are optional in the case where a translation according to D1 is not sought.

De la manière représentée, le socle 11 s'étend suivant le plan principal P et le bouton de commande 12 est superposé au socle 11 suivant l'axe principal D1 globalement orienté transversalement au plan principal P du socle 11, l'élément torique 18 étant placé entre une paroi supérieure 11a du socle 11 et une paroi inférieure 12a du bouton de commande 12 suivant l'axe principal D1. Ces dispositions garantissent un montage particulièrement aisé.As shown, the base 11 extends along the main plane P and the control button 12 is superimposed on the base 11 along the main axis D1 generally oriented transversely to the main plane P of the base 11, the toric element 18 being placed between an upper wall 11a of the base 11 and a lower wall 12a of the control button 12 along the main axis D1. These arrangements guarantee particularly easy mounting.

Selon un mode de réalisation, le bouton de commande 12 est mobile en translation par rapport au socle 11 le long de l'axe principal D1. Il est notamment possible de fabriquer de cette manière un bouton de commande se présentant sous la forme d'un bouton poussoir mobile par simple translation par rapport au socle 11.According to one embodiment, the control button 12 is movable in translation relative to the base 11 along the main axis D1. It is in particular possible to manufacture in this way a control button in the form of a push button movable by simple translation relative to the base 11.

De manière combinée ou alternative au mouvement de translation du bouton de commande 12, il peut être prévu que le bouton de commande 12 soit mobile en pivotement par rapport au socle 11 suivant au moins un axe de pivotement D2 orienté transversalement à l'axe principal D1. Il est notamment possible de fabriquer de cette manière un bouton de commande 12 se présentant sous la forme d'un bouton basculant mobile par simple pivotement autour de D2 par rapport au socle 11. Ces différentes variantes sont très faciles à obtenir, de manière économique et durable de surcroît, par une simple adaptation des inflexions générées le long de la périphérie de l'élément torique 18 par les éléments de réception 19. En fonction du nombre de zones d'appui total, il peut être prévu que le nombre d'axe de pivotement soit supérieur ou égal à 2 éventuellement.In combination with or as an alternative to the translational movement of the control button 12, it may be provided that the control button 12 is pivotally movable relative to the base 11 along at least one pivot axis D2 oriented transversely to the main axis D1. In particular, it is possible to manufacture in this way a control button 12 in the form of a rocking button movable by simple pivoting around D2 relative to the base 11. These different variants are very easy to obtain, in an economical and durable manner, moreover, by a simple adaptation of the inflections generated along the periphery of the toric element 18 by the receiving elements 19. Depending on the number of total support zones, it may be provided that the number of pivot axes is greater than or equal to 2 if necessary.

Selon un autre mode de réalisation tel que représenté, le bouton de commande 12 comprend une bague annulaire 21, mécaniquement indépendante du socle 11, présentant l'aptitude de mouvement par rapport au socle 11 qui a été évoquée précédemment. La bague annulaire 12 délimitant au moins deux zones d'appui 13a, 13b décalées entre elles sur le pourtour périphérique de la bague annulaire 21. Le bouton de commande 12 intègre alors deux zones d'appui 13a, 13b qui sont diamétralement opposées, et destinées à actionner deux interrupteurs 14a, 14b distincts eux-mêmes associés au pilotage respectif des première et deuxième fonctions électriques distinctes. En fonction de l'organisation des éléments de réception 19, la bague annulaire 21 a une aptitude d'un mouvement de basculement autour de deux points diamétralement opposés entre eux et chacun positionné entre les deux zones d'appui 13a ,13b. Les deux points de basculement sont positionnés le long de l'axe D2 qui a été évoqué ci-avant. En fonction de l'organisation des éléments de réception 19, la bague annulaire 21 a aussi une éventuelle aptitude supplémentaire de mouvement de translation suivant l'axe principal D1 permettant d'actionner ces deux interrupteurs 14a, 14b simultanément afin d'actionner sélectivement une troisième fonction électrique. Il est à noter que le nombre de zones d'appui, ici au nombre de deux à titre d'exemple, pourrait être égal à 3, à 4, ou supérieur ou égal à 5 en fonction des besoins associés au dispositif de commande manuelle 10. Il suffirait d'aménager un nombre d'inflexions adapté.According to another embodiment as shown, the control button 12 comprises an annular ring 21, mechanically independent of the base 11, having the ability to move relative to the base 11 which was mentioned previously. The annular ring 12 delimits at least two support zones 13a, 13b offset from each other on the peripheral periphery of the annular ring 21. The control button 12 then integrates two support zones 13a, 13b which are diametrically opposed, and intended to actuate two separate switches 14a, 14b themselves associated with the respective control of the first and second separate electrical functions. Depending on the organization of the receiving elements 19, the annular ring 21 has an ability to perform a tilting movement around two points diametrically opposed to each other and each positioned between the two support zones 13a, 13b. The two tilting points are positioned along the axis D2 which was mentioned above. Depending on the organization of the receiving elements 19, the annular ring 21 also has a possible additional ability of translational movement along the main axis D1 allowing these two switches 14a, 14b to be actuated simultaneously in order to selectively actuate a third electrical function. It should be noted that the number of support zones, here two in number for example, could be equal to 3, 4, or greater than or equal to 5 depending on the needs associated with the manual control device 10. It would suffice to arrange a suitable number of inflections.

Selon un mode de réalisation non limitatif, le dispositif de commande manuelle 10 comprend en outre un couvercle supérieur 22 solidaire du socle 11 et positionné dans une ouverture centrale 23 délimitée par la bague annulaire 21. Ce couvercle supérieur 22 peut éventuellement être fixe et présenter une simple fonction d'enjoliveur. Alternativement, il est possible qu'il soit mobile en translation et/ou en pivotement.According to a non-limiting embodiment, the manual control device 10 further comprises an upper cover 22 secured to the base 11 and positioned in a central opening 23 delimited by the annular ring 21. This upper cover 22 may optionally be fixed and have a simple trim function. Alternatively, it is possible for it to be movable in translation and/or in pivoting.

Dans un mode de réalisation particulier et alternatif tel que représenté, le couvercle supérieur 22 présente un bord périphérique 221, est solidaire du socle 11 par tout ou partie de son bord périphérique 221 (par exemple au moyen de pattes d'encliquetage 24), et présente une aptitude à se déformer par flexion lors de l'application manuelle d'une force d'appui par l'utilisateur du dispositif de commande manuelle 10 sur une zone centrale 222 du couvercle supérieur 22. La zone centrale 222 varie entre une configuration inactive stable dans laquelle le couvercle supérieur 22 est non fléchi lorsque la force d'appui est absente et une configuration active instable dans lequel le couvercle supérieur 22 est fléchi lorsque la force d'appui est appliquée. Le dispositif de commande manuelle 10 comprend un interrupteur supplémentaire 25 agencé de sorte que la zone centrale 222 du couvercle supérieur 22 place l'interrupteur supplémentaire 25 dans l'état inactif lorsque la zone centrale 222 occupe la configuration inactive stable et place l'interrupteur supplémentaire 25 dans l'état actif lorsque la zone centrale 222 occupe la configuration active instable. La zone centrale 222 peut être pourvue d'un tenon d'appui 26 destiné à venir appuyer contre l'interrupteur supplémentaire 25 dans la configuration active instable.In a particular and alternative embodiment as shown, the upper cover 22 has a peripheral edge 221, is secured to the base 11 by all or part of its peripheral edge 221 (for example by means of snap-fastening tabs 24), and has an ability to deform by bending during the manual application of a pressing force by the user of the manual control device 10 on a central zone 222 of the upper cover 22. The central zone 222 varies between a stable inactive configuration in which the upper cover 22 is not bent when the pressing force is absent and an unstable active configuration in which the upper cover 22 is bent when the pressing force is applied. The manual control device 10 comprises an additional switch 25 arranged so that the central zone 222 of the upper cover 22 places the additional switch 25 in the inactive state when the central zone 222 occupies the inactive configuration. stable and places the additional switch 25 in the active state when the central zone 222 occupies the unstable active configuration. The central zone 222 may be provided with a support pin 26 intended to press against the additional switch 25 in the unstable active configuration.

Alternativement, il est possible que le couvercle supérieur 22 soit mobile en translation et/ou en pivotement. En particulier, le couvercle supérieur 22 pourrait disposer également d'un deuxième élément torique (non représenté) conforme à l'élément torique 18 décrit en relation avec le bouton de commande 12, ce deuxième élément torique ayant des dimensions adaptées pour par exemple être inséré dans l'espace délimité par une circonférence interne de l'élément torique 18 précédemment décrit.Alternatively, it is possible for the upper cover 22 to be movable in translation and/or in pivoting. In particular, the upper cover 22 could also have a second toric element (not shown) conforming to the toric element 18 described in relation to the control button 12, this second toric element having dimensions adapted for example to be inserted into the space delimited by an internal circumference of the toric element 18 previously described.

Selon le mode de réalisation représenté aux Figures 1 à 9 non limitatif, le dispositif de commande manuelle 10 comprend des éléments de butée contre lesquels le bouton de commande 12 est en appui lorsque le bouton de commande 12 adopte un positionnement spatial par rapport au socle 11 dans lequel chaque zone d'appui 13a, 13b occupe sa position inactive stable sous l'effet de l'élément torique 18, les éléments de butée étant directement ou indirectement solidaires du socle 11. Ces éléments de butée peuvent en effet faire partie intégrante du socle 11 comme cela est visible sur la Figure 9, ou bien faire partie intégrante du couvercle supérieur 22, par exemple lui-même rendu solidaire du socle 11 par les pattes d'encliquetage 24.According to the embodiment shown in Figures 1 to 9 non-limiting, the manual control device 10 comprises stop elements against which the control button 12 bears when the control button 12 adopts a spatial positioning relative to the base 11 in which each support zone 13a, 13b occupies its stable inactive position under the effect of the toric element 18, the stop elements being directly or indirectly integral with the base 11. These stop elements can in fact be an integral part of the base 11 as can be seen in the Figure 9 , or form an integral part of the upper cover 22, for example itself made integral with the base 11 by the snap-fastening tabs 24.

Pour les caractéristiques de l'élément torique 18, il a été déterminé empiriquement qu'une solution donnant satisfaction sont que la matière de l'élément torique 18 soit du NBR (pour « Nitrile Butadiène Rubber » selon une terminologie anglo-saxonne) et que la dureté Shore A de l'élément torique 18 soit environ 70 ShA, donnant avec la pré-charge des nervures, un niveau d'effort adapté. A titre d'exemple, cet effort doit être le plus faible possible pour ne pas interférer dans l'effort d'actionnement des interrupteurs (généralement entre 1,5 et 2,5 N), tout en garantissant une remontée du bouton de commande 12 vers les positions inactives stables des zones d'appui 13a, 13b. Il doit être compris que l'actionnement d'un interrupteur donné se pratique en s'opposant à la somme de l'effort de rappel appliqué par l'élément torique 18 et de l'effort intrinsèque à l'actionnement de l'interrupteur 14a, 14b.For the characteristics of the toric element 18, it has been empirically determined that a satisfactory solution is that the material of the toric element 18 is NBR (for "Nitrile Butadiene Rubber" according to English terminology) and that the Shore A hardness of the toric element 18 is approximately 70 ShA, giving, with the pre-load of the ribs, a suitable level of force. For example, this force must be as low as possible so as not to interfere with the actuating force of the switches (generally between 1.5 and 2.5 N), while guaranteeing a rise of the control button 12 towards the stable inactive positions of the support zones 13a, 13b. It should be understood that the actuation of a given switch is carried out by opposing the sum of the return force applied by the toric element 18 and the force intrinsic to the actuation of the switch 14a, 14b.
