Abstract
Description
La présente invention a trait à un organe de commande doté d'un bouton de manipulation rotatif permettant d'actionner une première fonction, ledit bouton pouvant au surplus dans certains cas fonctionner en bouton-poussoir et être actionné selon des axes de déplacement différents, par exemple par pression axiale en certains points de sa périphérie. Les emplacements périphériques correspondants sont alors bien entendu indiqués à l'utilisateur au moyen d'une signalisation appropriée, et génèrent chacun la mise en oeuvre d'une fonction distincte.The present invention relates to a control member provided with a button. rotary manipulation for actuating a first function, said button which can in addition in certain cases function as a push button and be operated along different axes of movement, for example by axial pressure at certain points on its periphery. The slots corresponding devices are then of course indicated to the user by means of appropriate signaling, and each generates the activation work of a separate function.
Pour un bouton classique par exemple d'allure cylindrique, il est notamment possible de prévoir quatre zones d'appui périphériques situées à 90° l'une de l'autre, et permettant avec la rotation d'aboutir à la commande d'au moins cinq à six fonctions différentes.For a conventional button, for example with a cylindrical appearance, it is in particular possible to provide four peripheral support zones located at 90 ° from each other, and allowing the rotation to lead to the command at least five to six different functions.
Ce type d'organe de commande trouve sa place notamment dans les habitacles de véhicules automobiles, par exemple pour la commande des différentes parties d'un siège, ou pour le réglage des rétroviseurs droit et gauche, etc...This type of control device finds its place in particular in passenger compartments of motor vehicles, for example for controlling different parts of a seat, or for adjusting the right-hand mirrors and left, etc ...
Ces organes sont relativement complexes, car ils doivent transmettre des déplacements que l'on doit pouvoir clairement différencier malgré l'étroitesse relative de la surface sur laquelle s'effectue la commande. Les solutions actuelles utilisent les deux surfaces d'un circuit imprimé pour effectuer conjointement les fonctions correspondant aux déplacements rotatifs et axiaux dans l'espace réduit qui est alloué au bouton. Pour d'évidentes raisons économiques, ce type d'organe de commande doit cependant être conçu avec le minimum de pièces, celles-ci devant au surplus être les plus simples possibles, afin que les coûts à la fois de fabrication et de montage soient les plus réduits possibles.These organs are relatively complex because they must transmit displacements which one must be able to clearly differentiate despite the narrowness relative of the surface on which the order is made. The solutions use the two surfaces of a printed circuit to perform jointly the functions corresponding to the rotary and axial displacements in the reduced space that is allocated to the button. For obvious economic reasons, this type of control device must however be designed with the minimum of parts, these must in addition be the most simple possible, so that both manufacturing and assembly costs are as small as possible.
L'objectif principal de la présente invention est l'optimisation de la
conception des différents éléments participant au fonctionnement de l'organe
de commande, afin de proposer une solution globale simplifiée autant que
possible, et par conséquent fiable et offrant une pérennité élevée. Ainsi,
l'organe de commande qui en est l'objet n'utilise-t-il qu'une seule des faces
du circuit imprimé avec lequel il coopère, ce qui procure un gain d'espace
appréciable, de même qu'un avantage économique indéniable, tant au
niveau du nombre de pièces à assembler qu'à celui du temps de montage.
De fait, l'organe de commande selon l'invention est doté d'un bouton de
manipulation rotatif autour d'un premier axe, et qui peut être sollicité en
rotation autour d'au moins un axe secondaire contenu dans un plan
perpendiculaire au premier axe, par appui élastique sur au moins un
emplacement localisé au voisinage de la périphérie dudit bouton de
manipulation, et d'un circuit électrique doté de composants aptes à commuter
selon les sollicitations appliquées au bouton. Outre en rotation, le bouton peut
être dans certaines configurations manipulé en translation autour du premier
axe.The main objective of the present invention is the optimization of the design of the various elements participating in the operation of the control member, in order to propose a global solution simplified as much as possible, and therefore reliable and offering a high durability. Thus, the control member which is the object uses only one of the faces of the printed circuit with which it cooperates, which provides an appreciable gain in space, as well as an advantage. undeniable economic, both in terms of the number of parts to be assembled and in terms of assembly time.
In fact, the control member according to the invention is provided with a rotary manipulation button around a first axis, and which can be rotated around at least one secondary axis contained in a plane perpendicular to the first axis, by elastic support on at least one location located in the vicinity of the periphery of said manipulation button, and of an electrical circuit provided with components capable of switching according to the stresses applied to the button. In addition to rotation, the button can be in certain configurations manipulated in translation around the first axis.
Il se caractérise à titre principal en ce que ledit bouton est solidarisé à un actionneur qui transmet le mouvement de manipulation aux composants, lesquels sont disposés sur une face d'un support du circuit orientée en regard du bouton, la transmission s'effectuant via au moins deux pièces formant interface entre ledit actionneur et ledit circuit, d'une part un rotor solidaire en rotation de l'actionneur autour du premier axe, la liaison mécanique entre eux étant de plus prévue pour autoriser les déplacements relatifs selon le ou les axes secondaires, et d'autre part une platine fixe comportant des moyens élastiques de liaison avec le circuit électrique, lesquels sont disposés sensiblement au droit des emplacements périphériques d'appui.It is mainly characterized in that said button is secured to a actuator which transmits the manipulation movement to the components, which are arranged on one side of a circuit support facing opposite of the button, the transmission taking place via at least two parts forming interface between said actuator and said circuit, firstly a rotor integral with rotation of the actuator around the first axis, the mechanical connection between them being further provided for authorizing relative movements according to the secondary axes, and on the other hand a fixed plate comprising means elastic connecting to the electrical circuit, which are arranged substantially to the right of the peripheral support locations.
Les éléments essentiels de l'organe de l'invention sont donc, outre le bouton de manipulation, un actionneur, un circuit électrique et deux pièces, le rotor et la platine, dont l'une est fixe par rapport au bâti dans lequel est installé l'organe de commande et l'autre est mobile en rotation autour du premier axe de manipulation du bouton, et dont l'action s'effectue sur des composants disposés sensiblement dans un même plan et orientés vers les éléments constitutifs dudit organe.The essential elements of the organ of the invention are therefore, in addition to the manipulation button, an actuator, an electrical circuit and two parts, the rotor and plate, one of which is fixed relative to the frame in which is installed the control member and the other is movable in rotation about the first axis button manipulation, and whose action is performed on components arranged substantially in the same plane and oriented towards the elements constitutive of said organ.
La commande de cet organe se fait par conséquent soit en le faisant tourner autour dudit axe, soit en exerçant des pressions, centralement ou en des points précis de la périphérie.The control of this organ is therefore done either by doing it rotate around said axis, either by exerting pressure, centrally or by specific points on the periphery.
De préférence, le circuit électrique est implanté sur une même face d'un circuit imprimé, qui en constitue par conséquent le support précité. Cette solution est économiquement très favorable car elle permet un montage simplifié des différents composants sur ledit circuit imprimé d'une part, et de l'organe de commande dans son environnement d'autre part, sans avoir à prévoir l'implantation additionnelle d'autres composants / circuits imprimés, par exemple pour le fonctionnement d'une diode électroluminescente de signalisation.Preferably, the electrical circuit is located on the same face of a printed circuit, which therefore constitutes the aforementioned support. This solution is economically very favorable because it allows mounting simplified different components on said printed circuit on the one hand, and the control unit in its environment on the other hand, without having to provide for the additional installation of other components / printed circuits, for example for the operation of a light emitting diode signaling.
Selon une possibilité, une nappe en matériau isolant élastique peut être interposée entre d'une part la platine fixe et ses moyens élastiques de liaison avec le circuit électrique, et d'autre part ledit circuit.According to one possibility, a sheet of elastic insulating material can be interposed between on the one hand the fixed plate and its elastic connection means with the electrical circuit, and on the other hand said circuit.
Cette nappe joue un rôle mécanique, et peut par exemple comporter des parties mobiles de contacts de commutation du circuit. Elle assure alors, par ses propriétés mécaniques notamment élastiques, le retour en position stable desdites parties mobiles en phase de repos, ainsi qu'une sensation tactile particulière lorsqu'elle est sollicitée. D'autres solutions sans cette nappe sont bien entendu parfaitement utilisables.This sheet plays a mechanical role, and can for example include moving parts of circuit switching contacts. She then ensures, by its mechanical properties, in particular elastic properties, the return to a stable position said moving parts in the rest phase, as well as a tactile sensation particular when requested. Other solutions without this tablecloth are of course perfectly usable.
En fait, plus précisément, la platine fixe, formant l'un des constituants essentiels de l'organe de commande, prend la forme d'une plaque mince de laquelle dépassent des plots d'allure parallèle au premier axe, en nombre correspondant au nombre des emplacements d'appui périphériques, lesdits plots dépassant d'au moins un côté de la platine et étant disposés à l'extrémité libre d'au moins une languette flexible pour chaque emplacement d'appui, la ou les languettes étant pratiquées dans la platine et réalisées en un matériau élastique leur permettant de revenir en position de repos après action sur les plots.In fact, more precisely, the fixed plate, forming one of the constituents of the control unit, takes the form of a thin plate of which protrude studs parallel to the first axis, in number corresponding to the number of peripheral support locations, said studs projecting from at least one side of the plate and being arranged at the free end of at least one flexible tab for each location support, the tab or tabs being formed in the plate and produced in an elastic material allowing them to return to the rest position after action on the studs.
Selon une possibilité, pour chaque emplacement d'appui, les languettes flexibles sont au nombre de deux. Eiies sont superposées et reiiées entre elles à leur extrémité par un même plot de direction parallèle au premier axe. Cela permet d'améliorer la direction de transmission des efforts par appui sur le contact selon une direction parallèle audit premier axe. Selon l'une de ses fonctions principales, cette platine sert à transmettre une pression - exercée en périphérie du bouton de manipulation - au circuit électrique, via le cas échéant la nappe précitée. Une réinitialisation s'impose après chaque manipulation, d'où la nécessité des languettes élastiques. Cette pièce est de préférence réalisée en plastique rigide, mais présentant des caractéristiques mécaniques d'élasticité mises en oeuvre via les languettes.According to one possibility, for each support location, the tabs there are two flexible ones. They are superimposed and linked between they at their end by a same direction pad parallel to the first axis. This improves the direction of transmission of forces by pressing on the contact in a direction parallel to said first axis. According to one of his main functions, this plate is used to transmit pressure - exerted on the periphery of the manipulation button - to the electrical circuit, via the case the above-mentioned tablecloth. A reset is required after each handling, hence the need for elastic tabs. This piece is from preferably made of rigid plastic, but with characteristics mechanical elasticity implemented via the tabs.
La platine comporte en outre des moyens de guidage de l'actionneur vers les plots, qui assurent en fait la gestion des rotations autour des axes secondaires. Plus précisément, elle présente, dans sa zone centrale, un orifice de forme complexe, formé d'un nombre de fentes radiales convergentes au plus égal au nombre de plots/languettes disposés en périphérie, et se développant en direction de ceux-ci. De préférence, le nombre de fentes radiales est égal à celui des plots, et lesdites fentes se développent précisément en direction desdits plots.The plate also comprises means for guiding the actuator to the studs, which in fact manage the rotations around the axes secondary. More specifically, it presents, in its central area, a orifice of complex shape, formed by a number of radial slots converging at most equal to the number of pads / tabs arranged in periphery, and developing towards them. Preferably, the number of radial slots is equal to that of the studs, and said slots are develop precisely in the direction of said studs.
Ce guidage doit en fait être réalisé de manière suffisamment précise pour qu'il n'y ait pas d'interférence possible dans l'information qui est retransmise du bouton de manipulation au circuit électrique, quel que soit le nombre de plots qui doivent être actionnés.This guidance must in fact be carried out with sufficient precision so that there is no possible interference in the information that is retransmitted from the manipulation button to the electrical circuit, whatever the number of pads that must be actuated.
L'existence d'une pièce rotative actionnant des contacts impose dans nombre de cas, lorsqu'il y a plusieurs contacts distincts, un indexage de la position du rotor par rapport au bâti dans lequel est disposé l'organe de commande. C'est la raison pour laquelle il est prévu, selon l'invention, des moyens d'indexage dudit rotor, qui ne trouvent cependant à s'appliquer que dans certaines configurations.The existence of a rotating part actuating contacts requires in number of cases, when there are several separate contacts, an indexing of the position of the rotor relative to the frame in which the ordered. This is the reason why, according to the invention, provision is made for means for indexing said rotor, which however only apply in certain configurations.
Selon une possibilité, la platine comporte sur un côté, en périphérie immédiate des extrémités desdites fentes, une couronne à reliefs et dépressions, coopérant avec une protubérance saillant du rotor.According to one possibility, the plate has on one side, on the periphery immediately of the ends of said slots, a relief crown and depressions, cooperating with a protruding protrusion of the rotor.
En variante, ladite couronne pourrait être intégrée au rotor. Dans les deux cas, elle coopère avec un relief, bossage, doigt, etc... localisé respectivement sur le rotor ou disposé fixe par rapport au bâti, c'est-à-dire par exemple fixé audit bâti ou à la platine.As a variant, said crown could be integrated into the rotor. In the two cases, it cooperates with a relief, boss, finger, etc. located respectively on the rotor or disposed fixed relative to the frame, that is to say by example fixed to said frame or to the plate.
Selon une configuration possible, ce rotor comporte un logement central délimité par un muret cylindrique disposé sur une base constituée d'une plaque plane par exemple circulaire.According to a possible configuration, this rotor has a central housing delimited by a cylindrical wall placed on a base made up of a flat plate, for example circular.
L'actionneur, disposé entre le bouton de manipulation et la platine fixe, comporte un arbre central disposé selon le premier axe de rotation, de dimensions prévues pour qu'il puisse être guidé dans les fentes pratiquées dans la platine, et comportant un disque perpendiculaire dont le rayon est tel qu'il peut, lorsque l'actionneur est manipulé selon un axe secondaire, exercer une action sur le ou les plots périphériques de ladite platine, sur lesquels il repose en l'absence d'une telle manipulation.The actuator, located between the manipulation button and the fixed plate, has a central shaft arranged along the first axis of rotation, dimensions provided so that it can be guided through the slots in the stage, and comprising a perpendicular disc whose radius is such that it can, when the actuator is manipulated along a secondary axis, exert an action on the peripheral stud (s) of said plate, on which it rests in the absence of such manipulation.
C'est en définitive l'interaction entre l'arbre central et la platine fixe qui impose un dimensionnement particulier à la fois aux fentes radiales pratiquées dans la platine et audit arbre, de sorte que le guidage mentionné puisse avoir lieu.It is ultimately the interaction between the central shaft and the fixed stage which imposes a particular design both on the radial slots practiced in the plate and said shaft, so that the guidance mentioned can take place.
L'arbre central et le disque sont, selon une variante dans laquelle le bouton ne peut être utilisé comme bouton poussoir (c'est-à-dire subir une translation axiale), solidaires l'un de l'autre.The central shaft and the disc are, according to a variant in which the button cannot be used as a push button (i.e. undergo a axial translation), integral with one another.
Le disque peut être vu comme un organe d'amplification qui transmet, lorsque certaines conditions sont remplies (déplacement possible selon notamment l'existence d'une fente radiale dans la direction du mouvement), les mouvements selon les axes de rotation secondaires imprimés au bouton de manipulation.The disc can be seen as an amplifying organ which transmits, when certain conditions are met (travel possible depending in particular the existence of a radial slot in the direction of movement), the movements along the secondary axes of rotation printed on the button manipulation.
Outre avec la platine fixe, l'actionneur coopère comme on l'a mentionné auparavant avec le rotor mobile en rotation autour du premier axe.Besides the fixed plate, the actuator cooperates as mentioned previously with the mobile rotor rotating around the first axis.
A cet effet, une portion d'extrémité de l'arbre central s'ajuste, avec un jeu radial, dans le logement central du rotor, ladite portion étant limitée par une collerette formant butée axiale au contact du muret, le jeu radial autorisant un débattement angulaire de l'arbre par rapport aux axes secondaires, des moyens étant de plus prévus pour les solidariser en rotation par rapport au premier axe.For this purpose, an end portion of the central shaft adjusts, with a clearance radial, in the central housing of the rotor, said portion being limited by a flange forming an axial stop in contact with the wall, the radial clearance allowing a angular movement of the shaft relative to the secondary axes, means being further provided for securing them in rotation relative to the first axis.
Selon sa fonction principale, le rotor transmet au circuit électrique le mouvement rotatif autour du premier axe imprimé au bouton de manipulation. A cet effet, selon une possibilité, le muret est cylindrique et la portion d'extrémité de l'actionneur, également cylindrique, comporte au moins un ergot radial pouvant s'insérer dans une encoche pratiquée dans ledit muret, afin de les solidariser en rotation.According to its main function, the rotor transmits to the electrical circuit rotary movement around the first axis printed on the manipulation button. For this purpose, according to one possibility, the wall is cylindrical and the portion end of the actuator, also cylindrical, has at least one radial lug which can be inserted into a notch in said wall, in order to secure them in rotation.
Cette configuration est également favorable en ce qu'elle permet la transmission des mouvements cylindriques autour des axes secondaires, autre fonction remplie par le rotor. This configuration is also favorable in that it allows the transmission of cylindrical movements around secondary axes, another function fulfilled by the rotor.
En fait, de préférence, ladite portion d'extrémité comporte deux ergots radiaux opposés s'insérant dans deux encoches diamétralement opposées du muret.In fact, preferably, said end portion has two lugs opposite radials fitting into two diametrically opposite notches of the low wall.
Dans cette configuration, le débattement angulaire selon les axes secondaires est obtenu par appui de la collerette munissant l'arbre central de l'actionneur sur le muret logeant l'extrémité de ce dernier, créant ponctuellement un axe de pivotement uniquement pendant le mouvement de rotation et lorsque ce dernier est autorisé par les fentes radiales de la platine, dont les extrémités font alors office de butée. Alternativement, ces butées, voire le guidage du déplacement par rapport à ces axes secondaires, peuvent être gérés au niveau du franchissement par l'arbre central du tableau duquel dépasse le bouton de manipulation.In this configuration, the angular movement along the axes secondary is obtained by pressing the flange providing the central shaft with the actuator on the wall housing the end of the latter, creating punctually a pivot axis only during the movement of rotation and when the latter is authorized by the radial slots of the plate, whose ends then act as a stop. Alternatively, these stops, or even the guidance of the displacement relative to these secondary axes, can be managed at the crossing level by the central tree of the switchboard exceeds the manipulation button.
Selon une autre variante, l'arbre central et le disque peuvent être solidarisés uniquement en rotation, mais laissés libres, relativement l'un à l'autre, en translation. Dans ce cas, le bouton peut être utilisé comme bouton poussoir libre en translation selon un axe central.According to another variant, the central shaft and the disc can be secured only in rotation, but left free, relatively to one the other, in translation. In this case, the button can be used as a button pusher free in translation along a central axis.
Dans cette hypothèse, de préférence, le disque peut être guidé, lors des rotations autour des axes secondaires, entre la platine et le tableau traversé par l'arbre central et séparant le bouton des autres éléments de l'organe de commande.In this case, preferably, the disc can be guided during the rotations around the secondary axes, between the plate and the array crossed by the central shaft and separating the button from the other elements of the ordered.
Le tableau dont il est question masque le fonctionnement des différents organes de commande, dont seuls les boutons ou manettes externes sont accessibles à l'utilisateur.The table in question hides the operation of the different control elements, of which only external buttons or joysticks are accessible to the user.
Ce tableau et la platine comportent chacune par exemple un dôme dont le sommet est percé pour le passage de l'arbre central, lesdits dômes étant coaxiaux et formant un espace dans lequel est guidé le disque, équipé d'une part de nervures radiales à extrémité arrondie sur sa face en regard dudit tableau, et d'autre part d'un évidement en dôme sur l'autre face, lesdites extrémités arrondies et ledit évidement présentant des courbures correspondant respectivement à celle de leur dôme en vis-à-vis.This table and the plate each comprise for example a dome of which the top is drilled for the passage of the central shaft, said domes being coaxial and forming a space in which the disc is guided, equipped with a part of radial ribs with rounded end on its face opposite said table, and on the other hand a domed recess on the other side, said rounded ends and said recess having curvatures corresponding respectively to that of their opposite dome.
La possibilité d'un mouvement en translation relatif entre l'arbre central et le disque de l'actionneur impose en effet un guidage précis du disque pour des rotations autour des axes secondaires, qui ne peut pius dépendre de l'arbre central.The possibility of a relative translational movement between the central shaft and the actuator disc indeed requires precise guidance of the disc to rotations around the secondary axes, which cannot depend on the central tree.
Plus précisément, le dôme du tableau et l'évidement en dôme du disque comportent, à leur base, un relief annulaire présentant une surface intérieure dont la forme est prévue pour s'adapter respectivement à l'arrondi des nervures et au dôme de la platine.More specifically, the dome of the table and the dome recess of the disc have, at their base, an annular relief having an interior surface whose shape is designed to adapt respectively to the rounding of ribs and dome of the plate.
Lesdits reliefs annulaires permettent de réaliser un guidage correct en diminuant les contraintes, notamment de frottement, lors des mouvements relatifs des différentes pièces impliquées dans la liaison.Said annular reliefs make it possible to achieve correct guiding in reducing stresses, in particular friction, during movements relative of the different parts involved in the connection.
La liberté en translation arbre/disque peut être obtenue, selon une configuration possible, de la manière suivante : l'arbre central peut comporter des cannelures s'adaptant dans des glissières axiales d'un conduit axial traversant le disque, en vue de les bloquer en rotation et de permettre un guidage en translation. Ledit conduit axial comporte également une butée limitant la translation en direction du bouton de manoeuvre.Freedom in shaft / disc translation can be obtained, according to a possible configuration, as follows: the central shaft can include grooves fitting into axial slides of an axial duct crossing the disc, in order to block them in rotation and to allow a translational guidance. Said axial duct also includes a stop limiting the translation in the direction of the operating button.
Le rotor est entraíné en rotation, dans cette variante, par le disque. Celui-ci comporte à cet effet deux pattes orientées parallèlement à l'orifice de guidage de l'arbre central, et logées dans des encoches pratiquées dans le muret du rotor en vue d'une solidarisation en rotation, les dimensions respectives des encoches et des pattes autorisant un débattement angulaire autour des axes de rotation secondaires.The rotor is rotated, in this variant, by the disc. This one has for this purpose two tabs oriented parallel to the orifice of guiding the central shaft, and housed in notches in the rotor wall with a view to securing in rotation, the dimensions respective notches and tabs allowing angular travel around the secondary axes of rotation.
Il subsiste par conséquent un jeu entre les largeurs des encoches et celles desdites pattes, pour qu'il n'y ait pas d'opposition à la rotation, certes limitée, selon les axes secondaires.There is therefore a clearance between the widths of the notches and those of said legs, so that there is no opposition to rotation, certainly limited, depending on the secondary axes.
La liberté translative de l'arbre central par rapport au disque a évidemment un objectif. Il s'agit de permettre d'actionner, via une poussée strictement axiale, au moins un autre commutateur du circuit. A cet effet, l'extrémité libre de l'arbre central repose en appui sur un poussoir guidé en translation à l'intérieur du muret du rotor, et comportant au moins une patte susceptible de franchir la base du rotor pour actionner au moins un commutateur, le rotor comportant au moins un orifice à cet effet. Un ressort est de plus prévu pour rappeler ledit poussoir et l'arbre central en position de non-actionnement du ou des commutateurs, en l'absence de sollicitation axiale du bouton.The translational freedom of the central shaft in relation to the disc a obviously a goal. This is to allow to activate, via a push strictly axial, at least one other circuit switch. To this end, the free end of the central shaft rests on a pusher guided in translation inside the wall of the rotor, and comprising at least one lug likely to cross the base of the rotor to actuate at least one switch, the rotor having at least one orifice for this purpose. A spring is further provided for recalling said pusher and the central shaft in position non-actuation of the switch or switches, in the absence of solicitation axial of the button.
Plus précisément, le poussoir comporte une surface sensiblement perpendiculaire à l'axe de l'arbre central et deux pattes latérales guidées dans des glissières pratiquées dans la paroi interne du muret de sorte que ledit poussoir puisse être enfoncé dans ledit muret par action de l'arbre central, le ressort étant interposé entre ladite surface circulaire et la base du rotor. More specifically, the pusher has a surface which is substantially perpendicular to the axis of the central shaft and two guided side legs in slides made in the inner wall of the wall so that said pusher can be pushed into said wall by action of the shaft central, the spring being interposed between said circular surface and the base of the rotor.
Il est à noter que l'extrémité libre de l'arbre central est hémisphérique, de manière à ne pas entraver la possibilité de mouvements selon les axes secondaires.It should be noted that the free end of the central shaft is hemispherical, of so as not to hinder the possibility of movements along the axes secondary.
Selon l'invention, il peut être prévu un second muret coaxial d'allure cylindrique surmonté d'un bossage qui coopère avec la couronne d'indexation de la platine, qui est également solidaire de la base du rotor.According to the invention, a second coaxial low wall can be provided. cylindrical surmounted by a boss which cooperates with the crown indexing plate, which is also secured to the base of the rotor.
Ce second muret prend dans ce cas, en charge l'indexation de la rotation, en coopération avec la couronne à reliefs de la platine fixe dotée de plots périphériques.This second wall takes in this case, the indexing of the rotation, in cooperation with the relief crown of the fixed plate with peripheral studs.
Comme indiqué ci-dessus, une des fonctions principales de ce rotor est de transmettre un mouvement rotatif selon le premier axe. La transmission n'a bien entendu de sens que par rapport au circuit électrique par exemple disposé sur un circuit imprimé. Dans cette optique, la base du rotor comporte, associés à sa face opposée à celle qui présente les murets, des moyens de coopérer avec des composants, contacts ou pistes du circuit électrique, visant à réaliser au moins une commutation au cours de la rotation selon le premier axe, lesdits moyens permettant le cas échéant le passage d'au moins une patte du poussoir.As stated above, one of the main functions of this rotor is to transmit a rotary movement along the first axis. The transmission has of course meaningless compared to the electrical circuit for example arranged on a printed circuit. In this perspective, the base of the rotor includes, associated with its face opposite to that which presents the walls, means of cooperate with components, contacts or tracks of the electrical circuit, aiming to carry out at least one switching during the rotation according to the first axis, said means allowing, where appropriate, the passage of at least one pawl tab.
Ces moyens peuvent être divers, par exemple constitués d'une plaque conductrice comportant au moins un organe conducteur saillant du plan de la plaque, apte à glisser au moins temporairement sur des pistes du circuit électrique pour commuter l'état d'au moins un contact dudit circuit.These means can be various, for example consisting of a plate conductive comprising at least one conductive member projecting from the plane of the plate, able to slide at least temporarily on tracks of the circuit electric to switch the state of at least one contact of said circuit.
Toujours à propos dudit circuit électrique, celui-ci peut comporter des microcommutateurs disposés sous les plots élastiques dépassant de la platine. Les plots périphériques de la platine sont en fait déplacés selon un trajet qui est approximativement rectiligne, c'est-à-dire d'allure parallèle au premier axe, afin d'exercer une action adéquate sur ces commutateurs.Still on the subject of said electrical circuit, it may include microswitches placed under the elastic pads protruding from the platinum. The peripheral pads of the plate are in fact moved according to a path which is approximately straight, i.e. parallel to first axis, in order to exert an adequate action on these switches.
Selon une variante, les moyens de détection du changement d'état peuvent être magnétiques, et notamment utiliser l'effet Hall. Chaque capteur à effet Hall pourra détecter les modifications apportées au champ magnétique par un aimant mobile soit en translation à l'instar des plots précités, soit en rotation s'il est lié à la première pièce rotative. D'autres solutions, par exemple optiques, sont évidemment également possibles.According to a variant, the means for detecting the change of state can be magnetic, and in particular use the Hall effect. Each sensor Hall effect can detect changes to the magnetic field by a movable magnet either in translation like the aforementioned studs, or in rotation if it is linked to the first rotating part. Other solutions, for example optical, are obviously also possible.
L'arbre central de l'actionneur peut être disposé dans l'axe d'une diode électroluminescente du circuit électrique, et être prévu en matériau transparent, par exemple en polycarbonate, pour transmettre l'information lumineuse au niveau du bouton de manipulation.The central shaft of the actuator can be arranged in the axis of a diode electroluminescent of the electrical circuit, and be provided in material transparent, for example polycarbonate, to transmit information luminous at the level of the manipulation button.
Dans le cas de l'utilisation d'un circuit imprimé, tous les composants, y compris la diode, sont disposés sur la même face du circuit. Il s'agit d'un avantage déterminant par rapport aux dispositifs de l'art antérieur, dans lesquels on utilisait des circuits imprimés bifaces, avec les commutations à actionnement rotatif sur la face en regard du bouton, et les commutations générées par action en périphérie du bouton gérées par un bras traversant le circuit imprimé et coopérant avec un chariot mobile dans au moins deux directions. En général, la diode électroluminescente était alors disposée sur un autre circuit imprimé disposé sous le premier.In the case of the use of a printed circuit, all the components, including including the diode, are arranged on the same face of the circuit. It is a decisive advantage compared to the devices of the prior art, in which we used two-sided printed circuits, with the switching to rotary actuation on the face opposite the button, and the switches generated by action at the periphery of the button managed by an arm crossing the printed circuit and cooperating with a mobile carriage in at least two directions. In general, the light-emitting diode was then placed on another printed circuit placed under the first.
La multiplication des pièces et le montage rendaient alors l'organe de commande beaucoup plus onéreux que dans la configuration de l'invention.The multiplication of the parts and the assembly then made the organ of much more expensive control than in the configuration of the invention.

En référence à la figure 1, le bouton de manipulation (1) de l'organe de commande de l'invention se trouve sensiblement au milieu d'une platine (2) intégrant simultanément d'autres touches de commande (3, 4) et une zone (5) véhiculant des informations quant aux commandes mises en oeuvre.Referring to Figure 1, the manipulation button (1) of the control of the invention is located substantially in the middle of a plate (2) simultaneously integrating other control keys (3, 4) and a zone (5) conveying information as to the commands implemented.
Dans une telle application, l'organe de commande selon l'invention permet de déplacer chaque élément du siège du véhicule, préalablement sélectionné à l'aide des touches de commande référencées (3).In such an application, the control member according to the invention allows you to move each element of the vehicle seat beforehand selected using the control keys referenced (3).
Cet organe, sans le bouton de manipulation (1) qui apparaít en figure 1, est représenté de manière plus détaillée en figure 2. Il comporte, superposé, un actionneur (6), une platine intermédiaire (7), qui est fixe par rapport au bâti de l'ensemble (2), un rotor (8) mobile en rotation entraíné par l'actionneur (6), et une nappe (9) surmontant un circuit imprimé (10) intégrant les différents composants du circuit électrique. Ces éléments présentent une symétrie de révolution par rapport au premier axe.This body, without the manipulation button (1) which appears in Figure 1, is shown in more detail in FIG. 2. It comprises, superimposed, an actuator (6), an intermediate plate (7), which is fixed relative to the frame of the assembly (2), a rotor (8) movable in rotation driven by the actuator (6), and a sheet (9) surmounting a printed circuit (10) integrating the different electrical circuit components. These elements have a symmetry of revolution compared to the first axis.
La constitution et la fonction de ces différents composants est montrée plus en détail dans les figures qui suivent.The constitution and function of these different components is shown in more detail in the following figures.
Ainsi, comme cela apparaít en figure 3, l'actionneur (6) comporte un arbre central (11) dont l'extrémité supérieure est fixée au bouton de manipulation (1) apparaissant en figure 1. L'extrémité inférieure de cet arbre central (11) présente une portion (12) de diamètre supérieur à celui de l'arbre (11) dotée de deux ergots cylindriques (14, 14') diamétralement opposés.Thus, as appears in Figure 3, the actuator (6) has a central shaft (11) whose upper end is fixed to the button manipulation (1) appearing in figure 1. The lower end of this tree central (11) has a portion (12) of diameter greater than that of the shaft (11) provided with two diametrically opposite cylindrical pins (14, 14 ').
Au-dessus de la collerette, l'actionneur (6) présente un disque (15) surmonté par des nervures (16) dont le fonctionnement sera expliqué ci-après. Dans cette hypothèse, l'arbre (11) et le disque (15) sont solidarisés, voire réalisés en une seule pièce.Above the collar, the actuator (6) has a disc (15) surmounted by ribs (16) the operation of which will be explained below. In this hypothesis, the shaft (11) and the disc (15) are secured, or even made in one piece.
La portion d'extrémité (12) de l'arbre (11) est prévue pour se loger dans le logement (17) du rotor (8), logement (17) qui est délimité par un muret (18) présentant deux encoches (19, 19'). Ces dernières sont conçues pour loger les ergots (14, 14'), de façon à bloquer la liaison en rotation.The end portion (12) of the shaft (11) is intended to be housed in the housing (17) of the rotor (8), housing (17) which is delimited by a wall (18) having two notches (19, 19 '). These are designed to house the lugs (14, 14 '), so as to block the connection in rotation.
Le rotor (8) comporte au surplus un muret extérieur (20), d'épaisseur supérieure au muret (18).The rotor (8) further comprises an outer wall (20), of thickness higher than the low wall (18).
La platine (7), fixe par rapport au bâti (2), est interposée entre le disque (15) et la portion (12), c'est-à-dire au-dessus du rotor (8). Elle comporte, en son centre, un orifice (22) en forme de croix, c'est-à-dire présentant quatre fentes radiales de largeur telle que l'arbre central (11) peut s'y déplacer. En périphérie, cette platine (7) comporte quatre languettes (23), chacune dotée à son extrémité d'un plot (24) protubérant par rapport à ses deux faces.The plate (7), fixed relative to the frame (2), is interposed between the disc (15) and the portion (12), that is to say above the rotor (8). It includes, in its center, an orifice (22) in the shape of a cross, that is to say having four radial slots of width such that the central shaft (11) can move there. In periphery, this plate (7) has four tabs (23), each provided with its end of a stud (24) protruding with respect to its two faces.
Lorsque l'organe de commande (1) selon l'invention est monté comme cela est montré en figure 2, la périphérie du disque (15) est située au niveau desdits plots (24), qu'elle surmonte.When the control member (1) according to the invention is mounted as this is shown in Figure 2, the periphery of the disc (15) is located at said studs (24), which it overcomes.
Lorsque le bouton de manipulation (1) subit une rotation autour d'un axe secondaire perpendiculaire à l'axe (A), par appui sur l'une des zones représentées en figure 1 par des triangles disposés en regard du bouton de manipulation (1), le disque (15) répercute cette rotation à l'un des pions (24), qui se déplace grâce à une flexion de la lamelle (23) correspondante. Le plot (24) subit alors un déplacement sensiblement parallèle à l'axe (A), vers le bas, et exerce une pression sur une protubérance (25) de la nappe (9)(voir figure 7) située dans l'axe de son déplacement. Selon une possibilité, la protubérance (25) renferme une pastille métallique formant la partie mobile d'un contact disposé sur le circuit imprimé (10). Dans ce cas, une pression périphérique sur le bouton de manipulation revient à fermer un contact du circuit imprimé (10). La platine (7) est constituée en un matériau rigide, mais qui présente des propriétés d'élasticité telles que chaque lamelle revient en sa position initiale lorsque la pression sur le bouton de manipulation (1) cesse.When the manipulation button (1) is rotated around an axis secondary perpendicular to the axis (A), by pressing on one of the zones represented in Figure 1 by triangles arranged opposite the button manipulation (1), the disc (15) reflects this rotation to one of the pins (24), which moves by bending the corresponding strip (23). The stud (24) then undergoes a displacement substantially parallel to the axis (A), towards the bottom, and exerts pressure on a protuberance (25) of the ply (9) (see Figure 7) located in the axis of its movement. According to one possibility, the protuberance (25) contains a metal patch forming the movable part of a contact arranged on the printed circuit (10). In this case, pressure device on the manipulation button is like closing a contact of the printed circuit (10). The plate (7) is made of a rigid material, but which has elasticity properties such that each strip comes back in its initial position when pressing the manipulation button (1) stops.
La figure 4 montre cette même platine (7) isolée. L'orifice (22) en croix apparaít plus clairement qu'en figure 3.Figure 4 shows this same plate (7) isolated. The cross hole (22) appears more clearly than in Figure 3.
La rotation autour d'un axe secondaire est possible du fait du jeu de la portion (12) dans le muret (18), mais n'est possible que si l'arbre central (11) est guidé dans une fente radiale de l'orifice (22) de la platine (7).Rotation around a secondary axis is possible due to the play of the portion (12) in the wall (18), but is only possible if the central shaft (11) is guided in a radial slot of the orifice (22) of the plate (7).
La face inférieure du rotor (8) est montrée en figure 5. Elle comporte une pièce métallique (27), qui est fixée sur ladite face, et est elle-même dotée de deux languettes courbes (28, 28') qui peuvent glisser sur des pistes correspondantes du circuit imprimé (10), de manière à commuter l'état d'au moins un contact dudit circuit (10). A cet effet, les lames (28,28') sont légèrement fléchies de manière à dépasser du plan de la pièce (27), l'élasticité du métal permettant le contact par glissement sur les pistes du circuit imprimé (10).The underside of the rotor (8) is shown in Figure 5. It has a metal part (27), which is fixed on said face, and is itself provided with two curved tabs (28, 28 ') which can slide on tracks corresponding of the printed circuit (10), so as to switch the state of minus one contact of said circuit (10). For this purpose, the blades (28,28 ') are slightly bent so as to project beyond the plane of the part (27), the elasticity of the metal allowing sliding contact on the tracks of the printed circuit (10).
L'objet de la figure 6 est de préciser la liaison mécanique entre l'actionneur (6) et le rotor (8), comme cela a été expliqué auparavant. Les ergots (14, 14'), intégrés dans les encoches (19, 19'), assurent la liaison en rotation. Cette figure manifeste l'existence de quatre nervures (16) de rigidification du disque (15) de l'actionneur (6).The object of Figure 6 is to specify the mechanical connection between the actuator (6) and the rotor (8), as explained above. The lugs (14, 14 '), integrated in the notches (19, 19'), ensure the connection rotation. This figure shows the existence of four ribs (16) of stiffening of the disc (15) of the actuator (6).
La vocation de la figure 7 est de montrer plus particulièrement les interactions électriques qui prennent place à la base de l'organe de commande de l'invention. Ainsi, la plaque conductrice (27), en principe fixée au rotor (8), est ici représentée directement sur le circuit imprimé (10) avec lequel elle interagit.The purpose of Figure 7 is to show more particularly the electrical interactions that take place at the base of the organ of command of the invention. Thus, the conductive plate (27), in principle fixed to the rotor (8), is here represented directly on the printed circuit (10) with which it interacts with.
De même, la nappe en matériau souple et élastique (9), qui comporte en l'occurrence des parties mobiles du circuit électrique, par exemple des éléments de contacts, est représentée dans la position qui lui est allouée relativement d'une part au circuit imprimé (10), et d'autre part à la plaque métallique (27). Une diode électroluminescente (non représentée) peut par exemple être disposée au centre de la plaque (27), dans l'axe de l'arbre (11), lequel sera alors réalisé en un matériau conduisant la lumière.Similarly, the ply of flexible and elastic material (9), which comprises the occurrence of moving parts of the electrical circuit, for example contact elements, is shown in the position allocated to it relatively on the one hand to the printed circuit (10), and on the other hand to the plate metallic (27). A light emitting diode (not shown) can by example be placed in the center of the plate (27), in the axis of the shaft (11), which will then be made of a light-conducting material.
En figures 8 et 9, la variante dans laquelle le disque (15) est libre en translation par rapport à l'arbre (8) est présenté. Les références des différents composants que l'on retrouve dans les figures précédentes restent les mêmes. En fait, dans cette nouvelle variante, les modifications principales concernent l'existence d'un poussoir (29) disposé dans l'axe de l'arbre (8), et sur la surface supérieure duquel ce dernier repose.In FIGS. 8 and 9, the variant in which the disc (15) is free in translation with respect to the tree (8) is presented. The references of the different components found in the previous figures remain the same. In fact, in this new variant, the main changes relate to the existence of a pusher (29) disposed in the axis of the shaft (8), and on the upper surface of which the latter rests.
Ce poussoir (29) comporte deux pattes (30, 30') latérales pouvant
coulisser dans des glissières (31, 31') prévues dans le muret interne (18).
Comme dans la variante précédente, ce muret (18) comporte des encoches
(19, 19') prévues pour loger cette fois les pattes (32, 32') qui dépassent vers le
bas du disque (15). Comme cela a été indiqué auparavant, la largeur de ces
pattes (32, 32') est inférieure à la largeur des encoches (19, 19'), de manière
à absorber par exemple un débattement angulaire autour d'un axe de rotation
passant par lesdites pattes (32, 32') et perpendiculaire à l'axe de rotation
primaire.This pusher (29) has two lateral tabs (30, 30 ') which can slide in slides (31, 31') provided in the internal wall (18).
As in the previous variant, this wall (18) has notches (19, 19 ') provided to accommodate this time the tabs (32, 32') which protrude towards the bottom of the disc (15). As indicated above, the width of these legs (32, 32 ') is less than the width of the notches (19, 19'), so as to absorb, for example, an angular movement around an axis of rotation passing through said legs (32, 32 ') and perpendicular to the primary axis of rotation.
Un ressort (33) est interposé entre le poussoir (29) et le fond du rotor (8). Celui-ci est muni d'orifices permettant le passage des pattes (30, 30'), en vue de réaliser des commutations, par poussées axiales sur le bouton (1), de microcommutateurs disposés sur le circuit imprimé (10).A spring (33) is interposed between the pusher (29) and the bottom of the rotor (8). This is provided with holes allowing the passage of the legs (30, 30 '), in view to carry out switches, by axial pushes on the button (1), to microswitches placed on the printed circuit (10).
La pièce métallique (27) dotée des languettes courbes (28, 28') comporte elle-même deux orifices (34, 34') pour le passage des pattes (30, 30'). The metal part (27) with curved tongues (28, 28 ') itself has two orifices (34, 34 ') for the passage of the legs (30, 30').
Le fonctionnement se déduit notamment de la figure 9.The operation is deduced in particular from FIG. 9.
L'arbre (8) repose sur le poussoir (29) par l'intermédiaire de son extrémité libre hémisphérique (40). Cette particularité géométrique de l'extrémité de l'arbre (8) permet de réaliser des rotations autour d'axes secondaires du disque (15), lequel est guidé à cet effet entre les dômes (35, 36) dépassant respectivement de la paroi (2) fondamentale et de la platine (7).The shaft (8) rests on the pusher (29) by means of its hemispherical free end (40). This geometric peculiarity of the end of the shaft (8) allows rotations around axes secondary of the disc (15), which is guided for this purpose between the domes (35, 36) projecting respectively from the fundamental wall (2) and the plate (7).
Pour diminuer les efforts de frottements, le guidage se fait plus spécifiquement entre d'une part un bourrelet annulaire (37) dépassant de la paroi interne du dôme (35), et au contact duquel glissent les nervures (16) du disque (15), et d'autre part un bourrelet annulaire (38) dépassant d'un évidement en dôme (39) pratiqué dans le fond du disque, et qui est au contact du dôme (36) de la platine (7).To reduce friction forces, guidance is more specifically between on the one hand an annular bead (37) projecting from the inner wall of the dome (35), and in contact with which the ribs (16) of the disc (15), and on the other hand an annular bead (38) projecting from domed recess (39) formed in the bottom of the disc, and which is in contact the dome (36) of the plate (7).
Lorsque l'utilisateur exerce une force axiale sur le bouton (1), le poussoir (29), guidé dans le muret (18) du rotor (8) exerce une action vers le bas contrecarrée par le ressort (33), jusqu'à ce que les extrémités libres des pattes (30, 30') puissent exercer leur action électrique de commutation en coopération avec le circuit imprimé (10). Dès l'arrêt de la sollicitation, le ressort (33) rappelle l'arbre (8) et le poussoir (29) en position initiale de repos. Les fonctions rotative et d'actionnement selon les axes secondaires sont identiques à celles décrites pour la première variante.When the user exerts an axial force on the button (1), the pusher (29), guided in the wall (18) of the rotor (8) exerts a downward action counteracted by the spring (33), until the free ends of the legs (30, 30 ') can exercise their electrical switching action by cooperation with the printed circuit (10). Upon termination of the solicitation, the spring (33) recalls the shaft (8) and the pusher (29) in the initial rest position. The rotary and actuation functions along the secondary axes are identical to those described for the first variant.
L'organe de commande décrit ci-dessus ne constitue bien entendu qu'un exemple possible de cette invention. Celle-ci englobe d'autres variantes de formes et de configurations qui sont à la portée de l'homme de l'art.The control unit described above does not of course constitute than a possible example of this invention. This includes other variants of shapes and configurations that are within the reach of man from art.
