Description

Touche d'actionnement pour un clavier servant à l'interface homme-machine. Actuation key for a keyboard for the man-machine interface.
La présente invention concerne une touche d'actionnement pour un clavier servant à l'interface homme-machine et permettant notamment la saisie de données telles que des codes, intégrés dans des dispositifs électriques pour l'ouverture de portes, en particulier, en contrôle d'accès. Une telle interface est également utilisée dans des distributeurs de billets, dans des dispositifs de paiements électroniques par carte.The present invention relates to an actuation key for a keyboard used for the human-machine interface and in particular for the input of data such as codes, integrated into electrical devices for opening doors, in particular, in control of 'access. Such an interface is also used in cash dispensers, in electronic card payment devices.
Ainsi, il est actuellement largement répandu de proposer des dispositifs de contrôle d'accès prévoyant un clavier alphanumérique permettant la saisie d'un code d'accès actionnant le dispositif d'ouverture d'une porte. Un tel clavier doit pouvoir répondre à de nombreuses exigences en termes d'anti-vandalisme puisqu'il doit être le plus inviolable possible pour éviter les introductions frauduleuses et, en outre, ce clavier se trouvant généralement à l'extérieur de bâtiment, il doit pouvoir également être résistant quelles que soient les conditions environnementales (froid, chaleur, pluie, neige, poussières, etc.).Thus, it is currently widespread to provide access control devices providing an alphanumeric keyboard for entering an access code actuating the device for opening a door. Such a keyboard must be able to meet many requirements in terms of anti-vandalism since it must be the most inviolable possible to avoid fraudulent introductions and, moreover, this keyboard is generally outside the building, it must can also be resistant whatever the environmental conditions (cold, heat, rain, snow, dust, etc.).
Généralement un tel clavier comprend un circuit imprimé, sur lequel on vient générer un contact par impression sur le circuit à l'aide d'une touche dont la course est plus ou moins longue.Generally such a keyboard comprises a printed circuit, on which it comes to generate a contact by printing on the circuit with a key whose stroke is more or less long.
Ainsi, les claviers se répartissent généralement en deux groupes, ceux dans lesquels la touche vient actionner un piston générant un contact sur le circuit imprimé après une course courte et ceux dans lesquels les touches agissent sur le circuit imprimé par l'intermédiaire d'une membrane qui génère une course longue d'appui de la touche.Thus, the keyboards are generally divided into two groups, those in which the key actuates a piston generating a contact on the printed circuit after a short stroke and those in which the keys act on the printed circuit via a membrane which generates a long stroke of support of the key.
Bien entendu, l'aspect esthétique de ces claviers est variable. Il est possible de prévoir des touches rondes, des touches carrées ou de toutes autres formes possibles, des touches sur lesquelles les caractères sont imprimés ou bien sont gravés, etc. Par conséquent, il en résulte un nombre important de modèles différents présentant chacun des caractéristiques distinctes, comme par exemple des touches carrées à course longue, des touches rondes à course courte, etc...Of course, the aesthetic appearance of these keyboards is variable. It is possible to provide round keys, square keys or any other forms possible, keys on which the characters are printed or are engraved, etc. As a result, a large number of different models each having different characteristics, such as square long-stroke keys, round short-stroke keys, etc., result.
De plus, dans le cas des contrôles d'accès à des locaux, il est judicieux de prévoir un rétro éclairage des touches permettant de visualiser celles-ci facilement dans l'obscurité. Ainsi, certains modèles actuels proposent de prévoir une diode électroluminescente (LED) pour chaque touche. Dans le cas de LED rouges, le coût reste intéressant mais si on souhaite des LED bleues, le coût de fabrication d'un clavier avec un tel rétro éclairage en est augmenté.In addition, in the case of access control premises, it is advisable to provide a backlight keys to view them easily in the dark. Thus, some current models propose to provide a light emitting diode (LED) for each key. In the case of red LEDs, the cost remains interesting but if you want blue LEDs, the cost of manufacturing a keyboard with such a backlight is increased.
Sur le marché actuel, on propose donc soit des gammes de claviers standards, c'est-à-dire qui présentent des caractéristiques précises préalablement définies et figées, soit des claviers personnalisés, c'est-à-dire qu'ils sont réalisés en fonction de la demande particulière d'un client qui peut alors exprimer ses désirs quant à la course et la forme des touches et la couleur du rétro éclairage, notamment.On the current market, we therefore propose either ranges of standard keyboards, that is to say that have precise characteristics previously defined and fixed, or custom keyboards, that is to say that they are made in depending on the particular demand of a customer who can then express his desires as to the race and the shape of the keys and the color of the backlight, among others.
Toutefois, dans ce dernier cas, il est nécessaire quasiment à chaque fois de re« créer » un clavier.However, in the latter case, it is necessary almost every time to re-create a keyboard.
Afin de pallier ces inconvénients, la présente invention a pour but de proposer une touche d'actionnement ainsi qu'un clavier dans lequel les éléments constitutifs dudit clavier sont conformés et/ou peuvent être agencés les uns avec les autres de manière à permettre la conception de claviers personnalisés, présentant des caractéristiques différentes les uns des autres.In order to overcome these disadvantages, the object of the present invention is to provide an actuation key and a keyboard in which the constituent elements of said keyboard are shaped and / or can be arranged with each other so as to allow the design custom keyboards with different characteristics from each other.
A cet effet, l'invention a pour objet principal une touche d'actionnement pour clavier formant interface homme-machine du type comprenant au moins un circuit imprimé, une membrane, ladite touche agissant sur le circuit imprimé au moins par l'intermédiaire de la membrane, caractérisé en ce qu'elle est constituée d'une première partie appelée sous-touche et d'une seconde partie constituée d'un capot de recouvrement adaptable sur ladite sous-touche, ladite sous-touche étant logeable dans un compartiment de réception d'un plateau de réception positionnable au-dessus de la membrane, ledit compartiment étant pourvu d'un orifice au travers duquel ladite sous-touche est engageable au moins en partie pour venir en appui sur ladite membrane, de sorte qu'une pression sur ladite sous-touche génère un appui de la membrane sur le circuit imprimé, la course de la sous-touche étant limitée par le plateau.For this purpose, the main object of the invention is an actuation key for a keyboard forming a man-machine interface of the type comprising at least one printed circuit, a membrane, said key acting on the printed circuit at less through the membrane, characterized in that it consists of a first part called sub-key and a second part consisting of a covering cap adaptable on said sub-key, said sub-key being accommodable in a receiving compartment of a reception tray positionable above the membrane, said compartment being provided with an orifice through which said sub-key is engageable at least in part to bear against said membrane, so that a pressure on said sub-key generates a support of the membrane on the printed circuit, the stroke of the sub-key being limited by the plate.
Ainsi de manière avantageuse, la touche d'actionnement est constituée de deux parties l'une fonctionnelle, la sous-touche, l'autre le capot de recouvrement présentant à la fois les caractères d'ergonomie, d'esthétisme, d'anti- vandalisme, de résistance et autres. Il est ainsi possible de personnaliser les touches d'un clavier lors du montage, de manière très simple, en choisissant chaque capot de recouvrement d'une sous-touche parmi une pluralité de capots de recouvrement adaptables sur lesdites sous-touches, le reste des éléments du clavier restant identiques.Advantageously, the actuating button consists of two parts, one functional, the sub-key, the other the covering cover having both ergonomics, aesthetics, anti-wear characteristics. vandalism, resistance and others. It is thus possible to customize the keys of a keyboard during assembly, in a very simple way, by choosing each cover of a sub-key from a plurality of cover caps adaptable on said sub-keys, the rest of keyboard elements remaining identical.
Selon une première forme de réalisation, le plateau de réception comporte un unique compartiment de réception recevant ainsi une seule sous-touche. Ainsi de manière avantageuse, la touche d'actionnement se présente sous la forme d'une entité unitaire de base constituée au moins de la sous-touche et du plateau de réception sur laquelle est ensuite adaptable un capot de recouvrement.According to a first embodiment, the receiving tray comprises a single receiving compartment thus receiving a single sub-key. Advantageously, the actuation key is in the form of a basic unitary unit consisting at least of the sub-key and the receiving plate on which is then adaptable a covering cap.
Pour réaliser un clavier, il suffit alors de positionner autant de touches d'actionnement ainsi constituées que nécessaire. Une telle forme de réalisation permet notamment un espacement totalement libre entre les touches du clavier ainsi formé, un nombre quelconque de touches et une forme quelconque du clavier est aussi réalisable. Une touche d'actionnement selon l'invention offre une totale liberté dans la conception d'un clavier.To make a keyboard, it is then sufficient to position as many actuating keys thus formed as necessary. Such an embodiment allows in particular a completely free spacing between the keys of the keyboard thus formed, any number of keys and any form of the keyboard is also workable. An actuation key according to the invention offers complete freedom in the design of a keyboard.
Selon une seconde forme de réalisation, le plateau de réception comprend au moins deux compartiments de réception.According to a second embodiment, the receiving tray comprises at least two receiving compartments.
Ainsi, le plateau de réception peut accueillir une pluralité de touches d'actionnement selon l'invention. On réalise ainsi des plateaux de réception correspondant aux claviers de type classique tout en offrant la possibilité de personnaliser le clavier par l'intermédiaire des capots de recouvrement.Thus, the receiving tray can accommodate a plurality of actuating keys according to the invention. Receiving trays are thus produced corresponding to conventional type keyboards while offering the possibility of customizing the keyboard via cover caps.
La présente invention a donc également pour objet un clavier formant interface homme-machine, du type comprenant au moins un circuit imprimé, une membrane agissant sur le circuit imprimé, au moins une touche d'actionnement agissant sur le circuit imprimé au moins par l'intermédiaire de la membrane et une façade, caractérisé en ce que chaque touche d'actionnement est constituée d'une première partie appelée sous-touche et d'une seconde partie constituée d'un capot de recouvrement adaptable sur ladite sous-touche, ladite sous-touche étant logeable dans un compartiment de réception d'un plateau de réception positionnable au-dessus de la membrane, ledit compartiment étant pourvu d'un orifice au travers duquel ladite sous-touche est engageable au moins en partie pour venir en appui sur ladite membrane, de sorte qu'une pression sur ladite sous-touche génère un appui de la membrane sur le circuit imprimé, la course de la sous-touche étant limitée par le plateau.The present invention therefore also relates to a keyboard forming a human-machine interface, of the type comprising at least one printed circuit, a membrane acting on the printed circuit, at least one actuating key acting on the printed circuit at least by the membrane intermediate and a facade, characterized in that each actuating key consists of a first part called sub-key and a second part consisting of a cover cover adaptable on said sub-key, said sub -touche being accommodable in a receiving compartment of a reception tray positionable above the membrane, said compartment being provided with an orifice through which said sub-key is engageable at least in part to bear on said membrane, so that a pressure on said sub-key generates a support of the membrane on the printed circuit, the stroke of the sub-key being limited by the plate.
Selon une première forme de réalisation, le plateau de réception comporte un seul compartiment et le clavier est constitué d'une pluralité de touches d'actionnement réalisées sous forme d'entité unitaire constituée au moins de la sous-touche logée dans le plateau de réception et sur laquelle est ensuite adaptable un capot de recouvrement. Un tel clavier est donc totalement modulable.According to a first embodiment, the receiving tray comprises a single compartment and the keyboard consists of a plurality of actuation keys made as a unitary entity consisting of at least the sub-key accommodated in the receiving tray. and on which is then adaptable a cover cover. Such a keyboard is completely scalable.
Selon une seconde forme de réalisation d'un clavier selon l'invention, le plateau de réception comporte au moins deux compartiments et est positionnable au- dessus de la membrane.According to a second embodiment of a keyboard according to the invention, the receiving plate has at least two compartments and is positionable above the membrane.
Ainsi de manière avantageuse, dans un clavier selon l'invention, la touche d'actionnement est constituée de deux parties l'une fonctionnelle, la sous-touche, l'autre le capot de recouvrement présentant à la fois les caractères d'ergonomie, d'esthétisme, d'anti- vandalisme, de résistance et autres. Il est ainsi possible de personnaliser les touches de ce clavier lors du montage, de manière très simple, en choisissant chaque capot de recouvrement d'une sous-touche parmi une pluralité de capots de recouvrement adaptables sur lesdites sous-touches, le reste des éléments du clavier restant identiques.Thus, advantageously, in a keyboard according to the invention, the actuation key is made up of two parts, one functional, the sub-key, the other the covering cap having both the ergonomics characters, aestheticism, anti-vandalism, resistance and others. It is thus possible to customize the keys of this keyboard during assembly, in a very simple way, by choosing each cover cover of a sub-key from among a plurality of cover caps adaptable on said sub-keys, the rest of the elements of the keyboard remaining identical.
En outre, un clavier selon l'invention peut recevoir des membranes de type et fonctionnement différents pour générer un effet tactile distinct. En effet, la sous- touche étant positionnée dans le plateau de manière à venir en appui sur la membrane de sorte que la course de poussée de la sous-touche génère l'appui de la membrane sur le circuit imprimé, un simple changement de la membrane en conservant le même circuit imprimé peut permettre de modifier la course d'actionnement. Ainsi de manière avantageuse pour avoir une course longue, on met en place une membrane devant comporter des pastilles de carbone agissant directement sur le circuit imprimé et pour obtenir une course courte, on positionne des dômes sur le circuit imprimé.In addition, a keyboard according to the invention can receive membranes of different types and operation to generate a distinct tactile effect. Indeed, the sub-key being positioned in the plate so as to bear against the membrane so that the thrust stroke of the sub-key generates the support of the membrane on the printed circuit, a simple change of the Membrane retaining the same printed circuit can allow to change the actuation stroke. Thus advantageously to have a long stroke, it is set up a membrane to have carbon pellets acting directly on the printed circuit and to obtain a short stroke, is positioned domes on the printed circuit.
Ainsi, chaque interface obtenue avec un clavier selon l'invention présentera avantageusement toujours une structure de base similaire, en couches superposées, comprenant au moins un circuit imprimé, une membrane, un plateau, au moins une sous-touche, au moins un capot de recouvrement et une façade. Ce sont donc les choix opérés dans les éléments modulables le constituant que sont la membrane, les capots de recouvrement, le plateau (unitaire ou à compartiments multiples) et éventuellement la façade qui lui confèrent des caractéristiques spécifiques tant fonctionnelles (course longue ou courte ou autres) qu'ergonomiques, esthétiques (fonne, matière, couleur des capots de recouvrement constituant la partie visible des touches, couleur d'éclairage) en liaison avec les éléments « fixes » que sont le circuit imprimé et les sous-touches.Thus, each interface obtained with a keyboard according to the invention will advantageously always have a similar basic structure, in superimposed layers, comprising at least one printed circuit, a membrane, a tray, at least one sub-key, at least one cover of recovery and a facade. It is therefore the choices made in the modular elements constituting it that are the membrane, the covers, the tray (unitary or with multiple compartments) and possibly the facade that give it specific functional characteristics (long or short stroke or other ) that ergonomic, aesthetic (forms, material, color cover covers constituting the visible part of the keys, lighting color) in connection with the "fixed" elements that are the printed circuit and the sub-keys.
De plus, de manière très avantageuse d'un point de vue économique, pour obtenir un rétro éclairage, on prévoit des diodes électroluminescentes sur le circuit imprimé, la membrane étant choisie en un matériau permettant la diffusion de la lumière produite et les capots de recouvrement étant choisis pour permettre la diffusion de cette lumière en comportant par exemple au moins une partie transparente ou translucide, éventuellement colorée définissant la couleur du rétro éclairage.In addition, in a very advantageous manner from an economic point of view, to obtain a backlighting, light-emitting diodes are provided on the printed circuit, the membrane being chosen from a material allowing the diffusion of the light produced and the covering caps being chosen to allow the diffusion of this light, for example comprising at least one transparent or translucent, possibly colored part defining the color of the backlighting.
De préférence, le plateau est réalisé en un matériau tel que des matières plastiques comme les polycarbonates, les polyamides, les sous-touches étant en un matériau tel qu'un polycarbonate, un polyamide, et les capots de recouvrement en un matériau tel que polycarbonate, polyamide, aluminium, zamak, acier, etc, la façade étant réalisée également en un tel matériau.Preferably, the plate is made of a material such as plastics such as polycarbonates, polyamides, the sub-keys being made of a material such as a polycarbonate, a polyamide, and cover caps made of a material such as polycarbonate , polyamide, aluminum, zamak, steel, etc., the facade being also made of such a material.
Un clavier selon l'invention constitue donc une interface homme-machine parfaitement modulable et adaptable aux souhaits de l'utilisateur et ce, de manière économiquement avantageuse.A keyboard according to the invention thus constitutes a man-machine interface perfectly modular and adaptable to the wishes of the user and in a economically advantageous manner.
On décrira maintenant un exemple de réalisation de l'invention plus en détail en référence au dessin dans lequel : La figure 1 représente une vue en perspective éclatée d'un exemple de réalisation d'un clavier selon l'invention ;An embodiment of the invention will now be described in more detail with reference to the drawing in which: FIG. 1 represents an exploded perspective view of an exemplary embodiment of a keyboard according to the invention;
La figure 2 représente une vue en coupe du clavier de la figure 1 au niveau d'une touche dudit clavier ; etFigure 2 shows a sectional view of the keyboard of Figure 1 at a key of said keyboard; and
La figure 3 représente une vue en perspective d'une touche d'actionnement selon l'invention sous forme d'entité unitaire.FIG. 3 represents a perspective view of an actuation key according to the invention in the form of a unitary entity.
Un clavier selon l'invention comprend de manière connue en soi un circuit imprimé 1, une membrane 2 agissant sur ledit circuit 1 et des touches d'actionnement T du circuit 1 par l'intermédiaire de ladite membrane 2 ainsi qu'une façade.A keyboard according to the invention comprises, in a manner known per se, a printed circuit 1, a membrane 2 acting on said circuit 1 and actuating keys T of the circuit 1 via said membrane 2 as well as a facade.
Le clavier selon l'invention comporte en outre un plateau 4 positionnable au- dessus de la membrane 2 et dans lequel sont définis, dans l'exemple ici représenté, seize compartiments de réception 41 d'une première partie 3 d'une touche d'actionnement T encore appelée sous-touche constituant la partie fonctionnelle de la touche d'actionnement T. Chaque compartiment de réception 41 correspond dans l'exemple représenté ici à une surface sensiblement carrée.The keyboard of the invention further comprises a plate 4 positionable above the membrane 2 and in which are defined, in the example shown here, sixteen receiving compartments 41 of a first part 3 of a key d actuation T also called sub-key constituting the functional part of the operating key T. Each receiving compartment 41 corresponds in the example shown here to a substantially square surface.
Un compartiment 41 est en outre pourvu d'un orifice central au travers duquel ladite sous-touche 3 est engageable au moins en partie pour venir en appui sur la membrane 2 comme on peut le voir plus clairement à la figure 2.A compartment 41 is further provided with a central orifice through which said sub-key 3 is engageable at least in part to bear on the membrane 2 as can be seen more clearly in FIG.
Chaque sous-touche 3 présente sensiblement une bordure plane 31 dont le contour correspond au contour d'un compartiment 41 et qui entoure un téton 32 en saillie sur une face de ladite bordure 31, une tige 33 étant ménagée en saillie à l'opposé du téton 32 sur la face opposée de ladite bordure 31 et constituant la partie « piston » de la sous-touche 3 engageable au travers de l'orifice du compartiment de réception 41.Each sub-key 3 has substantially a flat border 31 whose contour corresponds to the contour of a compartment 41 and which surrounds a pin 32 projecting on a face of said border 31, a rod 33 being arranged projecting opposite the pin 32 on the opposite face of said border 31 and constituting the "Piston" portion of the sub-key 3 engageable through the orifice of the receiving compartment 41.
On peut prévoir des moyens de blocage en rotation de ladite sous-touche 3 dans ledit compartiment 41, grâce à un système de croisillons entre la tige 33 et le téton en saillie 32.Provision may be made for locking means in rotation of said sub-key 3 in said compartment 41, by virtue of a system of braces between the rod 33 and the protruding nipple 32.
De préférence, le plateau 4 présente des moyens de guidage ménagés à la périphérie de l'orifice de chaque emplacement 41 du plateau 4 et qui servent à guider la course de la tige 33 au travers de l'orifice et à empêcher la rotation de la sous-touche 3. Ces moyens de guidage peuvent être constitués de languettes 42 ménagée en saillie perpendiculairement au plateau 4.Preferably, the plate 4 has guide means arranged at the periphery of the orifice of each location 41 of the plate 4 and which serve to guide the stroke of the rod 33 through the orifice and to prevent rotation of the sub-key 3. These guide means may consist of tabs 42 formed projecting perpendicular to the plate 4.
La membrane 2 est conformée de sorte à présenter également des tétons 21 en saillie, ménagés de manière à être positionnés en regard d'un orifice d'un emplacement de réception 41 du plateau 4 et à l' extrémité desquels est en appui l' extrémité d'une tige 33 d'une sous-touche 3.The membrane 2 is shaped so as to also have lugs 21 projecting, arranged to be positioned opposite an orifice of a receiving location 41 of the plate 4 and at the end of which is supported the end a rod 33 of a sub-key 3.
Ainsi, lorsqu'on exerce une pression sur la sous-touche 3, la tige 33 exerce une pression sur le téton 21 de la membrane 2 qui est conformée pour se déformer et exercer à son tour une pression sur le circuit imprimé. La course d'actionnement de la sous-touche 3 est limitée par le plateau de réception 4 contre lequel ladite bordure 31 de la sous-touche 3 vient buter.Thus, when pressure is exerted on the sub-key 3, the rod 33 exerts pressure on the lug 21 of the membrane 2 which is shaped to deform and in turn exert pressure on the printed circuit. The actuating stroke of the sub-key 3 is limited by the receiving plate 4 against which said border 31 of the sub-key 3 abuts.
De manière à déterminer une course courte ou longue d'actionnement dans un clavier selon l'invention, il est possible déjouer sur le choix de la membrane 2.In order to determine a short or long stroke of actuation in a keyboard according to the invention, it is possible to outsmart the choice of the membrane 2.
Ainsi dans l'exemple représenté à la figure 2, on positionne des dômes 5 sur le circuit imprimé 1, la membrane 2 étant alors du type présentant un piston en silicone sans pastille de carbone. Dans le cas d'une course courte, la présence de dômes 5 raccourcit par conséquent la course d'actionnement des sous-touches 3.Thus in the example shown in FIG. 2, domes 5 are positioned on the printed circuit 1, the membrane 2 then being of the type having a piston in silicone without carbon pellet. In the case of a short stroke, the presence of domes 5 shortens the actuation stroke of the sub-keys 3.
Sur chacune des sous-touches 3 est adaptable un capot de recouvrement 6 servant en quelque sorte à habiller chaque sous-touche 3 et constituant la partie visible de la touche d'actionnement T.On each of the sub-keys 3 is adaptable a cover cover 6 serving to somehow to dress each sub-key 3 and constituting the visible portion of the actuating key T.
Comme on peut le voir à la figure 1, chaque capot de recouvrement 6 est constitué d'une bordure plane 61 entourant un téton 62 en saillie, ce téton 62 étant creux de manière à s'adapter sur le téton 32 de la sous-touche 3. La bordure plane 61 du capot 6 est donc positionnable en appui sur la bordure 31 plane de la sous-touche 3, le téton 62 du capot 6 coiffant le téton 32 de la sous-touche. La fixation du capot 6 sur une sous-touche 3 se fait par encastrement des éléments. L' anti-rotation du capot 6 sur la sous-touche 3 est garantie par des plots en saillie sur la bordure 31.As can be seen in FIG. 1, each cover cap 6 consists of a flat edge 61 surrounding a protruding protrusion 62, this stud 62 being hollow so as to fit on the pin 32 of the sub-key 3. The flat edge 61 of the cover 6 is therefore positionable in support on the flat edge 31 of the sub-key 3, the pin 62 of the cover 6 covering the pin 32 of the sub-key. The fastening of the cover 6 on a sub-key 3 is done by embedding the elements. The anti-rotation of the cover 6 on the sub-key 3 is guaranteed by studs projecting on the border 31.
On peut ensuite positionner une grille 7 entourant chaque touche T constituée du capot de recouvrement 6 sur la sous-touche 3, et formant la façade du clavier. On prévoit également une grille d'étanchéité ou joint 8 pour assurer l'étanchéité de l'ensemble ainsi formé.It is then possible to position a gate 7 surrounding each key T constituted by the cover cap 6 on the sub-key 3, and forming the front of the keyboard. There is also provided a sealing grid or gasket 8 to seal the assembly thus formed.
Le plateau 4 présente de préférence des bords latéraux 44 en saillie de part et d'autre dudit plateau 4 qui constituent les parois du clavier ainsi réalisé et qui lui confèrent un plus haut niveau de sécurité (anti-intrusion). De plus, il est envisageable de sertir l'ensemble constitué du circuit imprimé 1 et de la membrane 2 sur la face du dessous du plateau 4 grâce à des plots prévus à cet effet à l'arrière du plateau 4.The plate 4 preferably has lateral edges 44 projecting on either side of said plate 4 which constitute the walls of the keyboard thus produced and which confer a higher level of security (anti-intrusion). In addition, it is conceivable to crimp the assembly consisting of the printed circuit 1 and the membrane 2 on the underside of the plate 4 by means of studs provided for this purpose at the rear of the plate 4.
On obtient donc un clavier sous une forme relativement compact auquel il peut être adjoint au moins deux montants 9 pourvus d'orifices 91 pour la fixation dudit clavier et présentant des moyens d'encliquetage tels que des nervures 92 coopérant avec des moyens d'encliquetage complémentaires tels que des encoches 45 prévus sur les bords latéraux 44 du plateau 4.We thus obtain a keyboard in a relatively compact form to which it can be added at least two posts 9 provided with orifices 91 for fixing of said keyboard and having latching means such as ribs 92 cooperating with complementary latching means such as notches 45 provided on the lateral edges 44 of the plate 4.
Comme cela est visible à la figure 3, le plateau de réception 40 peut ne comporter qu'un seul compartiment de réception 41 d'une sous-touche 3, pour recevoir ensuite un capot de recouvrement 6. On peut alors foπner un clavier de forme quelconque à l'aide de ce type de touche d'actionnement T sous forme d'entité unitaire positionnable sur la membrane 2 de manière quelconque permettant de définir des emplacements quelconques des touches T sur un clavier.As can be seen in FIG. 3, the receiving tray 40 may comprise only one receiving compartment 41 of a sub-key 3, to then receive a covering cap 6. It is then possible to form a shape keyboard any using this type of operating key T as a unitary entity positionable on the membrane 2 in any way to define any locations of the T keys on a keyboard.
Les exemples ci-dessus, en particulier le nombre de compartiments de réception du plateau ou leur forme, n'ont été fournis que pour mieux fixer les idées et ne sauraient constituer une quelconque limitation de la portée de l'invention. The above examples, in particular the number of tray receiving compartments or their shape, have been provided only to better fix the ideas and can not constitute any limitation of the scope of the invention.
