Description

La présente invention a pour objet un dispositif de fixation de grilles ou plaques de décor et de protection d'appareils, en particulier d'appareils électriques et électroniques.The present invention relates to a device for fixing grids or decor plates and for protecting devices, in particular electrical and electronic devices.

Les grilles de décor et de protection telles que les grilles de façades d'appareils électroniques et les grilles de coffrets de haut-parleurs, qu'elles soient métalliques ou en matière plastique doivent dans la plupart des cas être fixées solidement sur leurs supports afin d'éviter leur vibration, qui peut être gênante et même provoquer leur détachement si elles ne sont pas fixées de façon sûre. Pour leur assurer une fixation résistant aux vibrations, on munit généralement ces grilles de pattes suffisamment longues dont on tord les extrémités, mais une telle opération n'est pas facilement automatisable et nécessite l'accès par l'arrière du coffret. Un autre dispositif connu de fixation de telles grilles consiste à les munir de pattes comportant une découpe dans laquelle s'encliquète un cliquet solidaire du coffret, mais une telle solution ne permet pas à la fixation des grilles de résister longtemps aux vibrations car les tolérances habituelles de fabrication en grande série ne permettent pas de garantir un positionnement assez précis de la découpe.The decorative and protective grilles such as the grids of facades of electronic devices and the grids of loudspeaker boxes, whether metallic or plastic must in most cases be securely fixed on their supports in order Avoid their vibration, which can be annoying and even cause their detachment if they are not securely fixed. To provide them with a vibration-resistant attachment, these grids are generally provided with sufficiently long legs, the ends of which are twisted, but such an operation cannot be easily automated and requires access from the rear of the cabinet. Another known device for fixing such grids consists in providing them with lugs comprising a cut-out in which a pawl secured to the box is snapped in, but such a solution does not allow the fixing of the grids to resist vibration for a long time because the usual tolerances mass production do not guarantee a fairly precise positioning of the cut.

La présente invention a pour objet un dispositif de fixation de grilles ou de plaques du type précité, leur garantissant une très bonne résistance aux vibrations, qui soit simple, qui puisse recevoir aussi bien des grilles en matière plastique que des grilles métalliques, et qui permette une automatisation facile de la mise en place de ces grilles.The present invention relates to a device for fixing grids or plates of the aforementioned type, guaranteeing them a very good resistance to vibrations, which is simple, which can receive both plastic grids and metal grids, and which allows easy automation of the installation of these grids.

Le dispositif de fixation de grilles de décor et de protection conforme à l'invention comporte des pattes de fixation sur ces grilles sur lesquelles sont formés des bossages s'encliquetant dans des fentes correspondantes du support de ces grilles, la partie de paroi de chacune de ces fentes qui coopère avec le bossage correspondant étant élastique.The device for fixing the decorative grids and protection according to the invention comprises fixing lugs on these grids on which bosses are formed which snap into corresponding slots in the support of these grids, the wall part of each of these slots which cooperates with the corresponding boss being elastic .

Selon une caractéristique avantageuse de l'invention, les bossages présentent une face d'introduction dans les fentes de pente plus faible que celle de la face arrière. Selon une autre caractéristique avantageuse de l'invention, on obtient l'élasticité des parois des fentes en pratiquant parallèlement à ces fentes, du côté des bossages, des fentes ayant approximativement les mêmes dimensions que les premières, la cloison de matière subsistant à chaque fois entre ces deux fentes ayant une épaisseur telle qu'elle lui assure une élasticité et une résistance suffisantes à l'encliquetage.According to an advantageous characteristic of the invention, the bosses have an insertion face in the slots with a lower slope than that of the rear face. According to another advantageous characteristic of the invention, the elasticity of the walls of the slots is obtained by practicing, parallel to these slots, on the side of the bosses, slots having approximately the same dimensions as the first, the partition of material remaining each time between these two slots having a thickness such that it gives it sufficient elasticity and resistance to snap-fastening.

Selon encore une autre caractéristique de l'invention, lorsque les grilles à fixer sont métalliques et doivent être électriquement reliées à un potentiel de référence, on forme sur ces grilles des pattes de connexion dont un des grands côtés est sensiblement rectiligne.According to yet another characteristic of the invention, when the grids to be fixed are metallic and must be electrically connected to a reference potential, connection lugs are formed on these grids, one of the long sides of which is substantially straight.

La présente invention sera mieux comprise à la lecture de la description détaillée de deux modes de réalisation, pris comme exemples non limitatifs et illustrés par le dessin annexé sur lequel :

  • - la figure 1 est une vue éclatée en perspective d'une partie de support et d'une grille-décor en matière plastique,
  • - la figure 2 est une vue en coupe de deux modes de réalisation du dispositif de l'invention pour des grilles métalliques et en matière plastique, et
  • - la figure 3 est une vue de détail agrandie de pattes de connexion de la grille métallique de la figure 2.
The present invention will be better understood on reading the detailed description of two embodiments, taken as nonlimiting examples and illustrated by the appended drawing in which:
  • FIG. 1 is an exploded perspective view of a support part and of a plastic decor grid,
  • FIG. 2 is a sectional view of two embodiments of the device of the invention for metallic and plastic grids, and
  • FIG. 3 is an enlarged detail view of connection tabs of the metal grid of FIG. 2.

L'invention est décrite ci-dessous en référence à une grille-décor destinée à être fixée sur la façade moulée en matière plastique d'un téléviseur sur laquelle sont fixés par exemple des haut-parleurs, des boutons de commande, ... Il est bien entendu que l'invention n'est pas limitée à une telle application, et qu'elle peut être mise en oeuvre pour la fixation d'une grille ou d'une plaque non perforée ou partiellement perforée de décor et/ou de protection sur une surface de support pour en permettre le montage par simple translation, donc facilement robotisable. Le dispositif de l'invention est particulièrement avantageux dans les cas où la surface de support transmet fréquemment des vibrations, comme c'est en particulier le cas pour des surfaces sur lesquelles sont fixés des haut-parleurs.The invention is described below with reference to a decor grid intended to be fixed to the molded plastic facade of a television on which are fixed, for example speakers, control buttons, etc. East it is understood that the invention is not limited to such an application, and that it can be implemented for fixing a grid or a non-perforated or partially perforated plate with decoration and / or protection on a support surface to allow mounting by simple translation, therefore easily robotizable. The device of the invention is particularly advantageous in cases where the support surface frequently transmits vibrations, as is in particular the case for surfaces on which speakers are fixed.

Sur la figure 1, on a représenté une partie de façade 1 de téléviseur, réalisée par moulage de matière plastique. On y distingue en particulier une découpe circulaire 2 derrière laquelle est fixé un haut-parleur (non représenté).In Figure 1, there is shown a front portion 1 of television, made by molding plastic. There are in particular a circular cutout 2 behind which is fixed a loudspeaker (not shown).

La façade 1 comporte plusieurs ensembles 3 de deux fentes répartis à sa périphérie pour la fixation d'une grille-décor 4A (en métal) représentée sur la partie gauche de la figure 2 ou 4B (en matière plastique) représentée sur la partie droite de la figure 2.The facade 1 comprises several sets 3 of two slots distributed around its periphery for fixing a decor grid 4A (made of metal) represented on the left part of FIG. 2 or 4B (made of plastic) represented on the right part of Figure 2.

Chaque ensemble 3 comporte deux fentes rectangulaires 5,6 parallèles entre elles. Dans le présent exemple, ces fentes sont parallèles aux côtés de la grille 4A (ou 4B). La largeur de la cloison 7 séparant les fentes 5,6 est telle que, compte tenu de l'épaisseur de la façade 1 autour des fentes 5,6, cette cloison présente une élasticité et une solidité suffisantes pour permettre le passage des bossages, décrits ci-dessous, formés sur les pattes de fixation de la grille et pour les retenir, que cette grille soit métallique ou en matière plastique. En effet, il est avantageux qu'un seul modèle de façade puisse recevoir aussi bien des grilles métalliques qu'en matière plastique d'esthétiques différentes, afin de personnaliser différentes séries de téléviseurs en changeant le minimum possible d'éléments.Each set 3 has two rectangular slots 5,6 parallel to each other. In the present example, these slots are parallel to the sides of the grid 4A (or 4B). The width of the partition 7 separating the slots 5,6 is such that, taking into account the thickness of the facade 1 around the slots 5,6, this partition has sufficient elasticity and solidity to allow the passage of the bosses, described below, formed on the lugs for fixing the grid and for retaining them, whether this grid is metallic or made of plastic. Indeed, it is advantageous that a single model of facade can receive both metal grids and plastic of different aesthetics, in order to personalize different series of televisions by changing the minimum possible of elements.

Dans le présent exemple, pour une épaisseur de la façade 1 autour des fentes 5,6 d'environ 3 mm, la largeur de la cloison 7 (c'est-à-dire la distance entre les fentes 5 et 6) est d'environ 2 mm, les fentes 5 et 6 ayant une longueur d'environ 15 à 25 mm.In the present example, for a thickness of the facade 1 around the slots 5.6 of approximately 3 mm, the width of the partition 7 (that is to say the distance between the slots 5 and 6) is about 2 mm, the slots 5 and 6 having a length of about 15 to 25 mm.

Dans le cas où la grille est métallique (grille 4A) elle comporte des pattes 8, d'une largeur d'environ 20 mm qui sont destinées à être introduites dans les fentes extérieures 5. Chacune de ces pattes 8 comporte sur sa face interne un bossage 9 réalisé par simple emboutissage. Le bossage 9, de forme sensiblement pyramidale, comporte une face d'introduction 10 sensiblement plane faisant un angle a1 avec le plan du reste de la patte 8. La face arrière 11 du bossage 9, qui constitue sa face active (c'est-à-dire celle qui retient la patte dans la fente), forme un angle a2 avec le plan du reste de la patte 8. Selon une caractéristique avantageuse de l'invention, l'angle a1 est inférieur à l'angle a2. Dans un exemple de réalisation, l'angle a1 est d'environ 30°, et l'angle a2 d'environ 60°. Ainsi, le faible angle a1 permet une introduction facile de la patte dans la fente correspondante, tandis que l'angle a2 plus grand assure une bonne retenue de la patte dans la fente en offrant une grande résistance au retrait de la patte. Bien entendu, la longueur de la face 11 est suffisamment grande pour compenser les tolérances de fabrication des grilles et des façades, c'est-à-dire que le rebord 12 de la fente 5 doit toujours porter sur la face 11 lorsque la grille est en place. Ainsi, le bossage 9 assure un rattrapage de jeu.In the case where the grid is metallic (grid 4A), it comprises tabs 8, of a width of approximately 20 mm which are intended to be introduced into the external slots 5. Each of these tabs 8 has on its internal face a boss 9 produced by simple stamping. The boss 9, of substantially pyramidal shape, has a substantially planar introduction face 10 making an angle a1 with the plane of the rest of the tab 8. The rear face 11 of the boss 9, which constitutes its active face (that is, that is to say that which retains the tab in the slot), forms an angle a2 with the plane of the rest of the tab 8. According to an advantageous characteristic of the invention, the angle a1 is less than the angle a2. In an exemplary embodiment, the angle a1 is approximately 30 °, and the angle a2 is approximately 60 °. Thus, the small angle a1 allows easy introduction of the tab into the corresponding slot, while the larger angle a2 ensures good retention of the tab in the slot by offering great resistance to the withdrawal of the tab. Of course, the length of the face 11 is large enough to compensate for the manufacturing tolerances of the grids and the facades, that is to say that the edge 12 of the slot 5 must always bear on the face 11 when the grid is in place. Thus, the boss 9 ensures a backlash.

Lorsque la grille est en matière plastique (4B), on la forme avec des pattes 13 dont les extrémités sont formées avec des bossages 14 similaires aux bossages 9 des pattes 8. Ces bossages 14 sont formés sur les faces extérieures de pattes 13 puisque ces pattes sont destinées à être introduites, selon le présent exemple, dans les fentes intérieures 6. De même que pour les bossages 9, les bossages 14 présentent une face d'introduction 15 ayant une pente plus faible que celle de la face arrière 16.When the grid is made of plastic (4B), it is formed with lugs 13, the ends of which are formed with bosses 14 similar to the bosses 9 of the legs 8. These bosses 14 are formed on the outer faces of legs 13 since these legs are intended to be introduced, according to the present example, into the interior slots 6. As for the bosses 9, the bosses 14 have an introduction face 15 having a lower slope than that of the rear face 16.

Lorsque la grille est métallique et que l'on désire la relier électriquement à la masse du téléviseur, à l'aide de cosses de connexion telles que les cosses femelles 17 représentées sur le dessin, on forme sur cette grille au moins une patte de connexion 18. Pour faciliter l'introduction de ces pattes dans les cosses 17, on les coupe de façon qu'un de leurs grands côtés, par exemple le côté 19 soit rectiligne. Etant donné que le pas des grilles peut être très variable, il est fort possible que si on découpe ces pattes à la largeur nécessaire sans placer correctement les traits de coupe, les deux côtés des pattes soient hérissés comme les côtés 20 des pattes 18, rendant difficile l'introduction des pattes dans les cosses 17.When the grid is metallic and you want to connect it electrically to the ground of the TV, using connection lugs such as the female lugs 17 shown in the drawing, at least one connection lug 18 is formed on this grid. To facilitate the introduction of these lugs into the lugs 17, they are cut so that one of their long sides, for example side 19 is straight. Since the pitch of the grids can be very variable, it is quite possible that if these legs are cut to the necessary width without correctly placing the cutting lines, the two sides of the legs are bristling like the sides 20 of the legs 18, making difficult to insert the legs into the pods 17.

Pour démonter la grille (4A ou 4B), on peut aussi bien agir directement sur les pattes que sur la façade. En effet, dans ce dernier cas, on peut par exemple prévoir à proximité des fentes 5,6 des fentes 21 dans lesquelles on introduit un tournevis que l'on pousse vers les fentes 5,6 si la grille est en matière plastique ou que l'on écarte de ces fentes si la grille est métallique, afin d'écarter la cloison 7 du bossage 14 ou 9. Ainsi, on peut démonter la grille sans l'abîmer et sans avoir obligatoirement accès aux pattes de fixation.To dismantle the grid (4A or 4B), you can also act directly on the legs as on the front. Indeed, in the latter case, it is possible for example to provide, near the slots 5, 6, slots 21 in which a screwdriver is introduced which is pushed towards the slots 5, 6 if the grid is made of plastic or that the 'we move away from these slots if the grid is metallic, in order to move the partition 7 away from the boss 14 or 9. Thus, we can disassemble the grid without damaging it and without necessarily having access to the fixing lugs.

Bien entendu, le nombre de pattes est fonction des dimensions de la grille, de sa forme et de sa rigidité.Of course, the number of legs depends on the dimensions of the grid, its shape and its rigidity.
