Description
La présente invention a pour objet un système de fixation d'une touche de commande sur un support selon le préambule de la revendication 1. Une telle touche est sensiblement plane, avec une position de repos et au moins une position de commande, comportant des moyens de positionnement pour positionner la touche sur le support, et deux lamelles situées dans un même plan, perpendiculaire au plan de la touche et constituées d'un matériau élastique pour, après une opération de commande par pression sur la touche, rappeler la touche en position de repos.The present invention relates to a system for fixing a control key on a support according to the preamble of claim 1. Such a key is substantially planar, with a rest position and at least one control position, comprising means positioning to position the key on the support, and two strips located in the same plane, perpendicular to the plane of the key and made of an elastic material for, after a command operation by pressing the key, recall the key in position rest.
De telles touches de commande sont utilisées dans les appareils audio, vidéo, notamment les autoradios pour commander les divers réglages : tonalité, son,... Une telle touche agit, par exemple, sur au moins un interrupteur qui délivre une impulsion lors de chaque pression exercée sur la touche.Such control keys are used in audio and video devices, in particular car radios to control the various adjustments: tone, sound, etc. Such a key acts, for example, on at least one switch which delivers a pulse during each pressure on the key.
Dans tous les cas, le système de fixation de la touche est soumis à des contraintes fonctionnelles et esthétiques notamment : grand nombre de manoeuvres, précision de positionnement par rapport à la façade esthétique, possibilité d'éclairage par l'intérieur de l'appareil, absence de bruit mécanique en vibrations.In all cases, the button fixing system is subject to functional and aesthetic constraints, in particular: large number of operations, positioning accuracy relative to the aesthetic facade, possibility of lighting from inside the device, absence of mechanical noise in vibrations.
Un système conforme au préambule est connu du brevet US-A-4,689,455 (Watanabe). Le système selon ce brevet comporte un ensemble de deux touches muni de deux lamelles assurant à la fois le positionnement et le rappel élastique des touches. Chaque touche actionne, indépendamment de l'autre, un interrupteur. Ses possibilités sont donc limitées.A system in accordance with the preamble is known from US-A-4,689,455 (Watanabe). The system according to this patent comprises a set of two keys provided with two strips ensuring both the positioning and the elastic return of the keys. Each key operates, independently of the other, a switch. Its possibilities are therefore limited.
La présente invention a pour but de supprimer ces inconvénients. Ce but est atteint par un système ayant les caractéristiques de la revendication 1.The present invention aims to eliminate these drawbacks. This object is achieved by a system having the features of claim 1.
Un tel système de fixation conforme au préambule est particulièrement remarquable en ce que le dit support est pourvu d'une ouverture en forme de T applati qui traverse son épaisseur, la jambe du T étant large par rapport aux ailes, un évidement sensiblement hémisphérique étant aménagé dans l'épaisseur du support en haut de la jambe du T, en ce la touche comporte deux autres lamelles centrales entre les deux susdites lamelles, formant ainsi quatre lamelles contigües, les deux lamelles centrales étant suffisamment écartées l'une de l'autre pour loger entre elles du côté de leur base un téton de forme hémisphérique similaire à l'évidement du support, et étant en outre reliées entre elles à leur autre extrémité par un becquet, l'ensemble étant agencé pour que, après pénétration élastique des deux lamelles extérieures dans les ailes du T et, simultanément, des deux lamelles centrales dans la jambe du T, premièrement le becquet s'encliquette sur le support en prenant appui sur la face du support opposée à l'évidement et coopère avec le téton alors logé dans l'évidement pour constituer les dits moyens de positionnement sous la forme d'un pivot autour duquel la touche est mobile, deuxièmement les deux lamelles latérales prennent appui dans les ailes du T pour constituer les dits moyens de rappel.Such a fixing system in accordance with the preamble is particularly remarkable in that the said support is provided with a flat T-shaped opening which crosses its thickness, the leg of the T being wide relative to the wings, a substantially hemispherical recess being arranged. in the thickness of the support at the top of the leg of the T, in that the key has two other central lamellae between the two aforementioned lamellae, thus forming four contiguous lamellae, the two central lamellae being sufficiently spaced from one another to accommodate between them on the side of their base a nipple of hemispherical shape similar to the recess of the support, and being further connected to each other at their other end by a spoiler, the assembly being arranged so that, after elastic penetration of the two outer strips in the wings of the T and, simultaneously, two central lamellae in the leg of the T, firstly the spoiler snaps onto the support by resting on the face of the support opposite the recess and cooperates with the stud then housed in the recess to constitute the said means of positioning under the shape of a pivot around which the key is movable, secondly the two lateral blades are supported in the wings of the T to constitute the so-called means e reminder.
Un tel système basé sur l'élasticité des lamelles est simple, peu coûteux, facile à monter et démonter.Such a system based on the elasticity of the slats is simple, inexpensive, easy to assemble and disassemble.
Avantageusement, la dite touche comporte en outre au moins une patte de positionnement inférieure en matériau élastique, perpendiculaire au plan de la touche, et munie d'un becquet d'encliquetage pour, en coopérant avec une ouverture du support, préciser la détermination de la position de repos.Advantageously, said key further comprises at least one lower positioning tab made of elastic material, perpendicular to the plane of the key, and provided with a snap-on spoiler for, by cooperating with an opening of the support, specifying the determination of the rest position.
Ainsi les lamelles élastiques de la touche sont soumises à une précontrainte ce qui a pour effet d'une part d'éliminer les jeux et donc les bruits mécaniques en cas de vibration, d'autre part d'assurer une parfaite reproductibilité de la position de repos.Thus the elastic strips of the key are subjected to a prestressing which has the effect on the one hand of eliminating the games and therefore the mechanical noises in the event of vibration, on the other hand of ensuring a perfect reproducibility of the position of rest.
Préférentiellement, la touche est pourvue d'un poussoir de commande à gauche de la touche et d'un poussoir de commande à droite de la touche, chacun d'eux étant en face d'un interrupteur de telle façon qu'ainsi les positions de commande sont au nombre de trois.Preferably, the button is provided with a control button to the left of the button and a control button to the right of the button, each of them being opposite a switch so that the positions of are three in number.
Ainsi, par exemple, en appuyant à droite on active un premier interrupteur, en appuyant à gauche, on active un deuxième interrupteur, et en appuyant au milieu, on active simultanément les deux interrupteurs.So, for example, pressing the right activates a first switch, pressing the left activates a second switch, and pressing in the middle activates both switches simultaneously.
La présente invention sera bien comprise au vu de la description d'un exemple de réalisation illustré par les dessins suivants :The present invention will be clearly understood in the light of the description of an exemplary embodiment illustrated by the following drawings:
La figure 1 représente le principe de la touche et du support.Figure 1 shows the principle of the key and the support.
La figure 2 représente, en coupe, le système de fixation monté.Figure 2 shows, in section, the mounting system mounted.
Sur la figure 1 la touche TO et son support SU sont représentés avant montage.In Figure 1 the TO key and its support SU are shown before mounting.
Le support SU comporte dans toute son épaisseur une ouverture ET en forme de 'T' applati.The support SU has, throughout its thickness, an opening ET in the form of a flattened 'T'.
La touche TO est manoeuvrée par pression exercée sur la surface plane SP; cette surface peut évidemment présenter d'autres aspects que celui représenté.The TO key is operated by pressure exerted on the flat surface SP; this surface can obviously have other aspects than that shown.
La touche TO est pourvue de 4 lamelles L1, LC1, LC2, L2, contigües 2 à 2 -L1, LC1 et LC2, L2-, sensiblement perpendiculaires au plan SP de la touche, et constituées d'un matériau élastique ce qui leur confère une certaine flexibilité par rapport au plan SP de la touche. En pratique, l'ensemble de la touche est en matière plastique moulée d'une seule pièce, le plan SP ayant une épaisseur adéquate pour lui assurer une rigidité suffisante.The TO key is provided with 4 lamellas L1, LC1, LC2, L2, contiguous 2 to 2 -L1, LC1 and LC2, L2-, substantially perpendicular to the plane SP of the key, and made of an elastic material which gives them some flexibility compared to the SP plan of the button. In practice, the whole of the key is made of plastic molded in one piece, the plane SP having an adequate thickness to provide it with sufficient rigidity.
Les lamelles extrêmes L1, L2 sont dimentionnées pour se loger, avec un jeu le plus réduit possible en épaisseur, dans les ailes A1, A2 de l'évidement ET du support SU.The extreme lamellae L1, L2 are dimensioned to be housed, with the smallest possible clearance in thickness, in the wings A1, A2 of the recess AND of the support SU.
Les lamelles LC1, LC2, sont reliées entre elles à leur extrémité par un becquet biseauté BE agencé pour, après pénétration dans la jambe JA de l'évidement ET, s'encliqueter sur la face arrière du support SU.The slats LC1, LC2, are connected to each other at their end by a beveled spoiler BE arranged to, after penetration into the leg JA of the recess ET, snap onto the rear face of the support SU.
Les lamelles LC1, LC2 sont suffisamment écartées l'une de l'autre pour y loger, du côté de leur base, un téton de forme hémisphérique SP1 relié à la touche de manière rigide.The lamellae LC1, LC2 are sufficiently spaced from one another to accommodate there, on the side of their base, a nipple of hemispherical shape SP1 connected to the key rigidly.
Similairement, le support comporte, en haut de la jambe du T, un évidement hémisphérique SP2 aménagé dans l'épaisseur du support, et agencé pour que, lors de l'introduction de la touche dans le support les deux éléments hémisphériques SP1, SP2 coopèrent pour constituer le pivot autour duquel la touche peut être actionnée. Le pivot et le becquet BE, après encliquetage, constituent les moyens de fixation et de positionnement de la touche en position de repos.Similarly, the support comprises, at the top of the leg of the T, a hemispherical recess SP2 arranged in the thickness of the support, and arranged so that, when the key is introduced into the support, the two hemispherical elements SP1, SP2 cooperate to constitute the pivot around which the key can be operated. The pivot and the spoiler BE, after snap-fastening, constitute the means for fixing and positioning the key in the rest position.
Les lamelles L1, L2, coopèrent également à la détermination de la position de repos mais elles constituent surtout les moyens de rappel en prenant appui sur les ailes A1, A2 du 'T', lors d'une opération de commande.The slats L1, L2 also cooperate in determining the rest position, but above all they constitute the return means by bearing on the wings A1, A2 of the 'T', during a control operation.
La figure 2 montre, en coupe, le système monté, en position de repos.Figure 2 shows, in section, the mounted system in the rest position.
Le support SU est visible avec son logement hémisphérique SP2 et une partie de l'évidement ET.The SU support is visible with its hemispherical housing SP2 and part of the ET recess.
La touche TO est visible avec son téton SP1 et son becquet encliqueté BE, la lamelle LC1 est montrée en pointillé.The TO button is visible with its stud SP1 and its snap-on spoiler BE, the LC1 strip is shown in dotted lines.
Pour faire mieux comprendre le problème esthétique, une façade FA1, FA2, esthétique est représentée et la touche comporte une jupe JU.To better understand the aesthetic problem, a facade FA1, FA2, aesthetic is shown and the key has a skirt JU.
Esthétiquement, il est important que d'une touche à l'autre, et d'un appareil à l'autre, le dépassement de la touche par rapport à la façade ne varie pratiquement pas. Dans ce but, une patte de positionnement inférieure PPI a été prévue, elle est souple, comme les lamelles, et comporte un becquet d'encliquetage BEI pour se loger dans une ouverture supplémentaire OS du support. La longueur de la patte PPI jusqu'à son becquet BEI assure un positionnement parfaitement reproductible de la touche en position de repos; la position de repos peut être prévue de telle sorte que les lamelles L1 et L2 sont légèrement précontraintes ce qui, notamment, élimine les jeux éventuels et évite des bruits mécaniques en cas de vibration.Aesthetically, it is important that from one key to another, and from one device to another, the protrusion of the key in relation to the front panel practically does not vary. For this purpose, a lower positioning leg PPI has been provided, it is flexible, like the slats, and has a BEI snap-in spoiler to be housed in an additional opening OS of the support. The length of the PPI tab up to its BEI spoiler ensures perfectly reproducible positioning of the button in the rest position; the rest position can be provided so that the slats L1 and L2 are slightly prestressed which, in particular, eliminates any play and avoids mechanical noise in the event of vibration.
Le système de fixation décrit ci-dessus fournit une touche mobile élastiquement autour d'un pivot et pourvue d'une position de repos.The fixing system described above provides a movable button resiliently around a pivot and provided with a rest position.
On peut prévoir, d'une manière préférentielle mais non limitative, trois positions de commandeIt is possible to provide, in a preferential but non-limiting manner, three control positions
Sur la figure 1, la touche est pourvue de deux poussoirs de commande PO1 et PO2; sur la figure 2 le poussoir PO1 est visible en vis à vis d'un interrupteur SW1; similairement un interrupteur SW2 est placé en vis à vis du poussoir PO2.In FIG. 1, the key is provided with two control push-buttons PO1 and PO2; in FIG. 2, the push-button PO1 is visible opposite a switch SW1; similarly a switch SW2 is placed opposite the pusher PO2.
En actionnant la touche sur sa partie gauche TOG, seul l'interrupteur SW1 est activé. En actionnant la touche sur sa partie droite TOD, seul le interrupteur SW2 est activé. En actionnant la touche sur sa partie centrale TOC, les deux interrupteurs SW1 et SW2 sont activés simultanément.By pressing the button on its left side TOG, only the switch SW1 is activated. By pressing the button on its right side TOD, only the switch SW2 is activated. By pressing the button on its central part TOC, the two switches SW1 and SW2 are activated simultaneously.
Le mot interrupteur n'est pas limitatif car il est clair que toute sorte de dispositif, tels que lames métalliques, contacts à dome, etc... peuvent être activés avec la touche à pivot décrite, laquelle fournit une course de quelques millimètres pour l'activation d'un dispositif quelconque.The word switch is not limitative because it is clear that any kind of device, such as metal blades, dome contacts, etc. can be activated with the pivot key described, which provides a stroke of a few millimeters for the activation of any device.
A titre indicatif, un tel système de fixation a été réalisé avec une touche en matière plastique de 30x15 mm avec des lamelles dont l'épaisseur est de 0,7 mm, la largeur de 2,5 mm et la longueur de 6 mm.As an indication, such a fastening system has been produced with a plastic button 30x15 mm with lamellae whose thickness is 0.7 mm, the width of 2.5 mm and the length of 6 mm.
Il est notable que le système de fixation selon l'invention occupe peu de place et, de ce fait, il est possible d'éclairer la touche par l'arrière avec, par exemple, une ampoule AM.It is notable that the fixing system according to the invention occupies little space and, therefore, it is possible to light the button from the rear with, for example, an AM bulb.
Il suffit alors que la zone du support repérée LU soit vide, ou translucide, pour que la lumière émise par l'ampoule AM illumine la touche par l'arrière pour faire apparaître une inscription ou un dessin.It then suffices for the area of the support marked LU to be empty, or translucent, for the light emitted by the bulb AM to illuminate the key from the rear to reveal an inscription or a drawing.
