Abstract

The multi message luminous button system has a button body (4) flexible mounted section (5) which is hollow and has a moving upper face (19). There is an etched mask (18) with messages. The inner see through sections (9) are divided up into sections (11,12) with a central opaque side section.

Description

L'invention concerne les touches lumineuses, en particulier les touches lumineuses multi-messages à éclairage indépendant destinées aux façades d'équipements, notamment aéronautiques ou automobiles.The invention relates to illuminated keys, in especially the illuminated multi-message illuminated keys independent for equipment facades, in particular aeronautics or automobiles.

Par message, on entend tout type de motif, de type symbolique ou alphanumérique, généralement porté en face avant des touches ou des boutons, indiquant la fonction du bouton, et le cas échéant, l'état de la ou des actions commandées par ladite touche ou ledit bouton.By message, we mean any type of pattern, type symbolic or alphanumeric, generally worn opposite before keys or buttons, indicating the function of the button, and if applicable, the status of the action (s) ordered by said key or said button.

Les touches lumineuses utilisées pour les équipements aéronautiques doivent assurer plusieurs fonctions malgré leur petite taille, ce qui contribue à la complexité des touches actuellement rencontrées. En effet, ces touches doivent simultanément assurer un contact électrique par pression sur un contacteur installé sur la façade, et une information au moyen d'une signalétique lumineuse, faisant en général appel à une face avant transparente munie d'un cache à la forme du message, rétroéclairée par un éclairage intérieur.The illuminated keys used for the equipment have several functions despite their small size, which contributes to the complexity of the keys currently encountered. Indeed, these keys must simultaneously provide electrical contact by pressure on a contactor installed on the front, and a information by means of luminous signage, making generally using a transparent front panel fitted with a cover in the form of the message, backlit by lighting inside.

Sur certaines touches, il est intéressant de pouvoir disposer d'au moins deux sources d'éclairage différentes, afin d'éclairer sélectivement deux messages différents ou plus, par exemple ON et OFF, ON étant éclairé en vert, et OFF en rouge. On désignera ici ce genre de touches par le terme touche lumineuse multi-messages à éclairages indépendants. Les sources lumineuses peuvent être de même couleur, ou de couleurs différentes.On some keys, it is interesting to be able have at least two different light sources, in order to selectively illuminate two different messages or more, for example ON and OFF, ON being lit in green, and OFF in red. We will designate here this kind of keys by the term multi-message light button with independent lighting. The light sources can be the same color, or different colors.

On connaít des touches comportant un socle équipé avec un contacteur électrique et d'au moins deux sources de lumière, et comportant un bouton poussoir en regard du contacteur et des sources lumineuses, ledit bouton saillant de la façade. On pourra par exemple se référer au document US-A-3 093 718. Ce bouton est constitué par un corps de bouton rigide réalisé par injection, lequel corps présente intérieurement un logement pour un poussoir muni d'un ressort, formant le moyen élastique de rappel du bouton et actionnant le contacteur. Ce bouton est fermé sur sa face avant par une étiquette (appelée vérine), comportant en transparence les deux messages à éclairer. L'intérieur du corps de bouton est cloisonné de telle façon que chaque source lumineuse éclaire un et un seul message. L'intérieur du corps de bouton est en général peint en blanc pour favoriser la diffusion de la lumière. Par ailleurs, un joint d'étanchéité rapporté est disposé autour du corps de bouton pour être serré entre le corps de bouton et la façade.We know keys with a base equipped with an electrical contactor and at least two sources of light, and having a push button next to the contactor and light sources, said protruding button the facade. We can for example refer to document US-A-3 093 718. This button consists of a button body rigid produced by injection, which body has internally a housing for a pusher provided with a spring, forming the elastic return means of the button and actuating the contactor. This button is closed on its front side by a label (called cylinder), comprising in transparency the two messages to clarify. The interior of the body of button is partitioned so that each light source illuminate one and only one message. The interior of the body button is usually painted white to favor the scattering of light. In addition, a joint seal is arranged around the button body to be clamped between the button body and the front.

La construction d'une telle touche fait appel à de nombreuses pièces, ce qui rend le produit cher à la fabrication et à l'entretien. Par ailleurs, la constitution de barrettes de touches sur un même socle est difficile. En outre, ces touches ne sont pas parfaitement étanches, de l'humidité pouvant s'infiltrer entre le corps de bouton et la façade, malgré la présence du joint d'étanchéité.Building such a touch calls for many parts, which makes the product expensive to manufacture and maintenance. Furthermore, the constitution of keypads on the same base is difficult. In furthermore, these keys are not perfectly waterproof, moisture that can infiltrate between the button body and the facade, despite the presence of the seal.

Le document US-A-4 535 396 décrit un bouton poussoir de conception analogue à celle du bouton poussoir précédent, mais réalisé de façon plus simple. Il comporte en effet une cage cloisonnée dans laquelle sont enfilés deux blocs translucides, la cage étant insérée dans un corps entre une vérine et un support de diodes, le tout formant un ensemble rigide lié à un ressort de rappel. Dans cet agencement, le bloc translucide n'assure qu'une fonction optique.Document US-A-4,535,396 describes a push button similar in design to that of the previous push button, but done in a simpler way. It includes effect a partitioned cage in which are threaded two translucent blocks, the cage being inserted in a body between a cylinder and a diode support, all forming a rigid assembly linked to a return spring. In this arrangement, the translucent block only performs an optical function.

On connaít par ailleurs des touches comprenant un bouton venu intégralement avec un rebord d'appui, auquel il est relié par un ligament périphérique souple formant l'élément élastique de rappel. Le contact électrique est obtenu grâce à la présence d'un doigt central intérieur venu de moulage avec le bouton et appuyant sur un contacteur électrique porté par la façade. Pour obtenir des touches lumineuses, on moule ce type de bouton dans un matériau translucide, puis on peint l'extérieur en noir. La face avant est ensuite gravée ou équipée d'une vérine, par exemple par collage. On obtient de manière très simple une touche lumineuse. Mais malheureusement, il n'est pas possible avec ce genre de touches d'obtenir un éclairage indépendant de plusieurs messages, en raison de la transparence du matériau utilisé, qui conduirait les différentes sources lumineuses indifféremment vers les différents messages portés par la face frontale, ce qui entraínerait une confusion dans la signalisation.We also know keys comprising a button fully integrated with a support rim, to which it is connected by a flexible peripheral ligament forming the elastic return element. The electrical contact is obtained thanks to the presence of an inner central finger molding with the button and pressing a switch electric carried by the facade. To get keys light, we mold this type of button in a material translucent, then the exterior is painted black. The face front is then engraved or equipped with a cylinder, for example by collage. You get a very simple touch light. But unfortunately, it is not possible with these kind of keys to get independent lighting of several messages, due to the transparency of the material used, which would drive the different light sources indifferently towards the different messages carried by the front face, which would cause confusion in signage.

L'état de la technique est également illustré par le document JP-A-11 73838. Ce document décrit un bouton poussoir comportant un élément unitaire de conception souple, comprenant un rebord d'appui et un corps de touche creux reliés par un ligament périphérique, le corps étant compartimenté par une cloison centrale. Cependant, le corps de touche est recouvert d'un capotage rigide, dont la présence est en fait rendue nécessaire par l'absence de bloc translucide à l'intérieur de la touche.The state of the art is also illustrated by document JP-A-11 73838. This document describes a button pusher comprising a unitary element of flexible design, comprising a support rim and a touch body hollows connected by a peripheral ligament, the body being compartmentalized by a central partition. However, the body key is covered with a rigid cover, the presence of which is actually made necessary by the absence of a block translucent inside the button.

On pourra enfin se référer au document JP-A-01 211195 qui décrit un agencement analogue. We can finally refer to document JP-A-01 211195 which describes a similar arrangement.

L'invention a pour but de concevoir une touche lumineuse multi-messages à éclairages indépendants, ne présentant pas les inconvénients et limitations précités. The invention aims to design a light touch multi-message with independent lighting, not presenting not the aforementioned drawbacks and limitations.

Il s'agit plus particulièrement d'une touche lumineuse équipant une façade d'équipement, notamment un équipement aéronautique, comprenant un rebord d'appui, et un corps de touche creux se terminant par une face frontale de manoeuvre recouverte d'un masque gravé selon des messages à éclairer, ledit corps de touche étant lié audit rebord d'appui au moyen d'un ligament périphérique, ledit corps, ledit ligament et ledit rebord étant réalisés de manière unitaire dans un matériau souple. Selon l'invention, un bloc de matériau translucide, divisé en pavés par au moins une cloison opaque sensiblement perpendiculaire à la face frontale, est enchâssé dans l'intérieur du corps de touche pour s'étendre jusqu'à la face frontale de manoeuvre de la touche.It is more particularly a light touch equipping an equipment facade, in particular an equipment aeronautical, comprising a support rim, and a hollow button body ending in a front face of maneuver covered with an engraved mask according to messages to illuminate, said touch body being linked to said edge of support by means of a peripheral ligament, said body, said ligament and said flange being formed so unitary in a flexible material. According to the invention, a block of translucent material, divided into blocks by at least an opaque partition substantially perpendicular to the face frontal, is embedded in the interior of the body to extend to the front operating side of the touch.

Le bloc translucide de la touche lumineuse précitée permet non seulement de conduire la lumière, mais aussi de rigidifier le corps de touche qui est de conception souple, ce qui élimine la nécessité d'un capotage rigide.The translucent block of the aforementioned light button not only conducts light, but also stiffen the finger body which is flexible in design, which eliminates the need for rigid casing.

Ainsi, si la façade est équipée de deux sources de lumière différentes, chaque pavé conduit indépendamment la lumière de l'une des sources, chaque chemin lumineux étant séparé de l'autre par la cloison opaque. Chaque source peut donc éclairer un message différent faisant partie du masque commun, chacun en regard d'un des pavés.Thus, if the facade is equipped with two sources of different light, each block independently leads the light from one of the sources, each light path being separated from the other by the opaque partition. Each source can so illuminate a different message that is part of the mask common, each facing one of the paving stones.

Avantageusement, le rebord d'appui est conformé pour présenter une excroissance périphérique faisant fonction de joint d'étanchéité saillant du côté de la façade. Ainsi, l'étanchéité est assurée sans qu'il soit nécessaire d'avoir recours à un joint rapporté. Advantageously, the support flange is shaped to present a functional outgrowth seal protruding from the side of the facade. Thus, sealing is ensured without the need for it to use an attached seal.

Selon un premier mode de réalisation de la touche, les pavés sont jointifs au niveau de la face frontale. According to a first embodiment of the key, the pavers are joined at the front face.

La cloison opaque les sépare, mais les pavés sont toujours solidaires par un ligament de faible épaisseur pris entre la cloison et le masque. Les pavés sont ainsi plus facilement manipulables lors de la fabrication de la touche, surtout si l'on utilise plus de deux pavés. En outre, le ligament précité renforce la face frontale du corps de touche.The opaque partition separates them, but the paving stones are always joined by a thin ligament caught between the partition and the mask. The cobblestones are like this more easily handled during the manufacture of the key, especially if more than two blocks are used. In addition, the aforementioned ligament strengthens the front face of the body button.

Selon une variante de réalisation, les pavés sont disjoints. On obtient ainsi une séparation optique totale des deux chemins lumineux, puisque la cloison opaque peut s'étendre jusqu'au masque. According to an alternative embodiment, the pavers are disjoint. A total optical separation is thus obtained of the two light paths, since the opaque partition can extend to the mask.

Selon un premier aspect, le masque est une étiquette portant en transparence des messages à éclairer. According to a first aspect, the mask is a label carrying transparent messages to enlighten.

Il est ainsi très facile de rapporter le masque sur la face avant, ce qui permet de produire des touches lumineuses indifférenciées et de les particulariser par l'étiquette qu'elles portent. It is therefore very easy to put the mask on the front panel, which produces bright touches undifferentiated and to particularize them by the label they wear.

Selon un deuxième aspect, un revêtement opaque recouvre la face de manoeuvre, laissant apparaítre des messages à éclairer sur la face de manoeuvre. In a second aspect, an opaque coating covers the operating face, leaving messages appear to be lit on the operating face.

Les messages s'obtiennent facilement par des procédés de gravure laser. Ces messages pourront selon le cas être secrets lumière éteinte, ou être rendus lisibles de jour au moyen d'une peinture translucide. Messages are easily obtained by processes laser engraving. These messages may, as appropriate be secret light off, or be made readable from day by means of a translucent paint.

Pour les touches du type comportant un doigt intérieur de manoeuvre d'un contacteur électrique de la façade, le doigt est avantageusement porté par la cloison opaque. For keys of the type with an inner finger operating an electrical contactor on the facade, the finger is advantageously carried by the opaque partition.

Selon un premier mode de fabrication de la touche, les pavés sont collés dans le corps de touche. According to a first method of manufacturing the key, the paving stones are glued into the key body.

Selon un deuxième mode, les pavés sont encliquetés dans le corps de touche. According to a second mode, the pavers are snapped in the key body.

Selon un troisième mode, le corps de touche avec sa ou ses cloisons, et le rebord d'appui associé, sont venus de surmoulage sur les pavés, en étant réalisés en un matériau opaque. According to a third mode, the finger body with its or its partitions, and the associated support ledge, came overmolding on the pavers, being made of a material opaque.

L'invention concerne également une barrette de touches lumineuses, constituée d'une pluralité de touches juxtaposées présentant l'une au moins des caractéristiques précitées, le rebord d'appui desdites touches formant un rebord d'appui périphérique de ladite barrette. The invention also relates to a keypad luminous, consisting of a plurality of juxtaposed keys having at least one of the characteristics mentioned above, the support rim of said keys forming a peripheral support rim of said strip.

D'autres caractéristiques et avantages de l'invention apparaítront plus clairement à la lumière de la description qui suit d'un mode de réalisation particulier non limitatif de l'invention, en référence aux figures des dessins annexés parmi lesquelles :

Sur les figures 1 et 2, un équipement 1 du type calculateur ou encore boítier de commande aéronautique est équipé d'une façade 2 dans laquelle est ménagé au moins un orifice 3 pour accueillir en saillie de la façade un corps de touche 4 parallélépipédique formant, avec un rebord d'appui 5, une touche 6 selon l'invention. Le rebord d'appui 5 est pris en sandwich entre l'équipement 1 proprement dit et sa façade, de sorte que ce rebord 5 est immobilisé entre ces deux éléments. Le corps de touche 4 est lié au rebord d'appui 5 par un ligament ou membrane périphérique souple 7, faisant office de ressort pour repositionner le corps de touche 4 après sa manoeuvre. Le corps de touche 4, le ligament 7 et le rebord d'appui 5 sont réalisés de manière unitaire dans un matériau souple.In FIGS. 1 and 2, equipment 1 of the type computer or aeronautical control box is fitted with a facade 2 in which at least one orifice 3 to accommodate a body projecting from the facade key 4 parallelepiped forming, with a rim support 5, a key 6 according to the invention. The flange support 5 is sandwiched between equipment 1 properly says and its facade, so that this ledge 5 is immobilized between these two elements. The key body 4 is linked at the support rim 5 by a peripheral ligament or membrane flexible 7, acting as a spring to reposition the key body 4 after its operation. The touch body 4, the ligament 7 and the support flange 5 are made of unitarily in a flexible material.

Ce rebord d'appui 5 présente en outre, en saillie vers la façade 2, un joint 8 d'étanchéité, destiné à empêcher que de l'humidité s'infiltre sous la façade 2. Le joint 8 est en l'espèce venu de matière avec le rebord d'appui 5, et ne constitue donc pas un composant séparé comme c'était le cas pour les touches antérieures. A l'intérieur du corps de touche est enchâssé un bloc 9 de matériau translucide, par exemple en silicone, contre un rebord 10 intérieur au corps de touche, ledit bloc 9 étant séparé en deux pavés 11 et 12 au moyen d'une cloison opaque 13, séparant les deux pavés 11 et 12 sur toute la dimension du corps de touche 4. La cloison 13 sépare ainsi le bloc 9 dans toute la longueur du corps de touche 4. Ces pavés 11 et 12 participent à la rigidité structurale du corps de touche 4, qui est quant à lui réalisé en matériau souple. Ces pavés 11 et 12 peuvent rester attachés entre eux par un ligament de faible épaisseur au niveau de la face frontale 19, comme cela a été représenté à la figure 2. L'ensemble des pavés est ainsi plus facile à manipuler lors de la fabrication de la touche, et la face frontale est renforcée. En variante, ils peuvent être complètement indépendants. La variante à pavés disjoints n'a pas été représentée ici.This support flange 5 further has, projecting towards the front 2, a gasket 8, intended to prevent only moisture permeates under the facade 2. The joint 8 is in this case integral with the rim support 5, and therefore does not constitute a separate component as was the case with the previous keys. AT the inside of the key body is embedded a block 9 of translucent material, for example silicone, against a rim 10 inside the key body, said block 9 being separated into two blocks 11 and 12 by means of an opaque partition 13, separating the two blocks 11 and 12 over the entire dimension of the key body 4. The partition 13 thus separates the block 9 along the entire length of the key body 4. These blocks 11 and 12 participate in the structural rigidity of the body of button 4, which is made of flexible material. These blocks 11 and 12 can remain attached to each other by a thin ligament on the frontal side 19, as shown in Figure 2. The assembly pavers are thus easier to handle during manufacturing of the button, and the front side is reinforced. Alternatively, they can be completely independent. The variant with separate pavers has not been shown here.

Ces pavés 11,12 sont ici retenus dans le corps de touche par un rebord périphérique interne 10, permettant la tenue des pavés 11,12 dans le corps de touche 4. These blocks 11, 12 are here retained in the body of touched by an internal peripheral rim 10, allowing the holding blocks 11,12 in the key body 4.

En variante, ces pavés 11,12 peuvent être collés dans le corps de touche 4. As a variant, these pavers 11, 12 can be glued in the key body 4.

En variante encore, on surmoule ces pavés 11,12 avec un matériau opaque, du silicone par exemple, pour former la touche directement autour des pavés. Cette dernière variante est tout particulièrement intéressante pour rationaliser la fabrication, surtout si on veut réaliser des barrettes de touches, comme cela est décrit plus loin en référence à la figure 3.In another variant, these pavers are molded 11,12 with an opaque material, for example silicone, to form the key directly around the paving stones. This last variant is particularly interesting to rationalize manufacturing, especially if you want to make keypads, as described later in reference to figure 3.

Les pavés 11 et 12 conduisent chacun la lumière provenant de deux sources lumineuses 16 et 17 liées à l'équipement et se trouvant respectivement derrière les pavés 11 et 12. Ces sources lumineuses peuvent par exemple être des diodes électroluminescentes (LED), commandées pour s'allumer selon une logique définie et implantées dans l'équipement. La présence de la cloison opaque 13 empêche qu'une source lumineuse affectée à un pavé n'éclaire le pavé adjacent. Chaque pavé conduit donc la lumière d'une seule source.The blocks 11 and 12 each lead the light coming from two light sources 16 and 17 linked to equipment and located respectively behind the paving stones 11 and 12. These light sources can for example be light-emitting diodes (LEDs), controlled for light up according to a defined logic and established in equipment. The presence of the opaque partition 13 prevents that a light source assigned to a paver illuminates the paver adjacent. Each block therefore conducts the light of a only source.

Si les deux sources sont de couleurs différentes, on obtient ainsi une touche bicolore. En variante, on peut obtenir deux couleurs différentes avec deux sources de même couleur, en teintant les pavés, ou en les équipant de filtres colorés internes ou externes.If the two sources are different colors, you get a two-tone touch. Alternatively, we can get two different colors with two sources the same color, by tinting the pavers, or by equipping them with filters colored internal or external.

Les pavés 11 et 12 s'étendent jusqu'à une face frontale de manoeuvre 19 , ou face avant, pour conduire la lumière vers l'extérieur de la touche lumineuse 6. Cette face avant 19 est recouverte d'un masque 18. Ainsi qu'on peut le constater en figure 1, ces masques 18 laissent apparaítre en transparence deux motifs pour chaque touche lumineuse bi-messages, dont certains correspondent à un message lisible tel que (ON, OFF, CALL, STOP, MECH), d'autres représentant un motif symbolique (carré, rectangle, ou toute autre forme), chacun se trouvant à l'aplomb d'un pavé. Chaque motif ou message est donc éclairé par une seule source.Pavers 11 and 12 extend to one side maneuvering front 19, or front face, for driving the light outside the light button 6. This front face 19 is covered with a mask 18. As we can see in Figure 1, these masks 18 let appear transparently two patterns for each light touch bi-messages, some of which correspond to a message readable such as (ON, OFF, CALL, STOP, MECH), others representing a symbolic motif (square, rectangle, or any other form), each one plumb with a paving stone. Each motif or message is therefore illuminated by a single source.

Ce masque 18 peut être constitué d'une étiquette collée sur la face avant 19. En variante, on peut fabriquer ce masque en couvrant la face avant 19 d'un revêtement opaque, puis en éliminant la partie de ce revêtement correspondant aux motifs ou messages désirés, par exemple par un procédé de gravure laser.This mask 18 can consist of a label glued to the front face 19. As a variant, it is possible to manufacture this mask by covering the front face 19 with an opaque coating, then eliminating the part of this corresponding coating to the desired patterns or messages, for example by a laser engraving process.

Les messages peuvent être secrets, c'est-à-dire que les messages ne sont pas lisibles de jour s'ils ne sont pas éclairés; alternativement, les messages peuvent être rendus lisibles de jour au moyen, par exemple, d'une peinture translucide. The messages can be secret, that is to say that messages cannot be read during the day if they are not enlightened; alternatively, messages can be rendered readable by day using, for example, paint translucent.

La cloison 13 porte en saillie un doigt 14 dirigé vers l'équipement, pour actionner un contacteur électrique associé 15 solidaire de l'équipement 1. The partition 13 carries a projecting finger 14 directed to the equipment, to activate an electrical contactor associated 15 secured to the equipment 1.

L'agencement de l'intérieur du corps de touche est mieux visible à la figure 3, qui présente une série de corps de touche 52 regroupés en une barrette notée 50, comportant un rebord périphérique d'appui 51 commun, formé à partir des rebords d'appui des touches lumineuses ainsi juxtaposées. Le joint d'étanchéité périphérique (non visible sur la figure) garantit alors globalement l'étanchéité pour toute la barrette ainsi formée. Il va de soi que les touches peuvent être regroupées selon tout type d'agencement géométrique, et notamment en tableau de touches.The arrangement of the interior of the key body is best seen in Figure 3, which presents a series of key body 52 grouped into a bar marked 50, comprising a peripheral peripheral flange 51, formed at from the support edges of the illuminated buttons as well juxtaposed. The peripheral seal (not visible in the figure) then guarantees overall tightness for the entire strip thus formed. It goes without saying that keys can be grouped according to any type of geometric arrangement, and in particular in table of keys.

On distingue sur la figure 3 la cloison 13 séparant les pavés 11 et 12 sur toute la longueur de chaque corps de touche 52, et portant en saillie du rebord d'appui 51 un doigt de manoeuvre 14.We distinguish in Figure 3 the partition 13 separating blocks 11 and 12 over the entire length of each body of button 52, and bearing projecting from the support flange 51 a operating finger 14.

L'invention n'est pas limitée au mode particulier de réalisation qui vient d'être décrit, mais bien au contraire entend couvrir toute variante qui, avec des moyens équivalents, reproduirait les caractéristiques essentielles énoncées plus haut. The invention is not limited to the particular mode of realization which has just been described, but on the contrary intends to cover any variant which, with resources equivalent, would reproduce the essential characteristics set out above.

En particulier, la forme de la touche n'est pas limitée à un parallélépipède, mais peut au contraire prendre tout type de forme, polygonale, circulaire ou autre. In particular, the shape of the key is not limited to a parallelepiped, but can on the contrary take any type of shape, polygonal, circular or other.

On peut en outre augmenter le nombre de cloisons, et partant le nombre de pavés, et donc le nombre de messages. Enfin, par exemple pour réaliser des touches tri- ou quadri- messages, la ou les cloisons ne sont pas forcément rectilignes.We can also increase the number of partitions, and therefore the number of blocks, and therefore the number of messages. Finally, for example to make tri- or quad messages, the partition (s) are not necessarily rectilinear.
