Description

"Procédé de calage et de fixation d'un dispositif électrique encastré et dispositif pour la mise en oeuvre d'un tel procédé" "Method of wedging and fixing an embedded electrical device and device for implementing such a method"
La présente invention concerne un procédé de calage et de fixation d'un dispositif électrique encastré. L'invention concerne également le dispositif permettant la mise en oeuvre du procédé.The present invention relates to a method of wedging and fixing an embedded electrical device. The invention also relates to the device allowing the implementation of the method.
Le dispositif électrique est en fait constitué, d'une part, par un appareil électrique classique dont l'implantation s'effectue généralement dans un mur, tel qu'un interrupteur, une prise de courant, une prise téléphone, une prise PERITEL (marque déposée) et, d'autre part, par un enjoliveur extérieur.The electrical device is in fact constituted, on the one hand, by a conventional electrical device whose implantation is generally carried out in a wall, such as a switch, an electrical outlet, a telephone outlet, a PERITEL outlet (brand deposited) and, on the other hand, by an external hubcap.
Le plus communément, la pose d'interrupteurs ou de prises se fait en deux temps, de la manière suivante. Il y a tout d'abord une fixation de l'appareil dans la boîte d'encastrement, par vis ou par griffes qui s'écartent. Il y a, ensuite, une fixation de l'enjoliveur sur l'appareil, par vis apparentes (peu esthétique) ou par clipage.Most commonly, the installation of switches or sockets is done in two stages, as follows. First of all there is a fixing of the device in the recessing box, by screws or by claws which deviate. There is, then, a fixing of the hubcap on the device, by visible screws (unattractive) or by clipping.
Ces deux types de fixation ont l'inconvénient de ne pas fixer l'enjoliveur parfaitement contre le mur. En effet, lorsque l'électricien scelle, au plâtre, la boîteThese two types of fixing have the disadvantage of not fixing the hubcap perfectly against the wall. When the electrician seals the box with plaster
CONFIRMATION C0PV d'encastrement dans le mur, il lui est très difficile de la caler en respectant l'axe perpendiculaire et le plan du mur (ni en saillie, ni en retrait).C0PV CONFIRMATION of embedding in the wall, it is very difficult for it to wedge while respecting the perpendicular axis and the plane of the wall (neither projecting, nor recessed).
Or, les systèmes actuels d'accrochage des enjoliveurs et des appareils électriques ne permettent pas le rattrapage de cet inconvénient.However, the current attachment systems for hubcaps and electrical devices do not allow this drawback to be remedied.
Il en résulte qu'il est très rare que les quatre angles de l'appareil électrique, qui lui servent de butée, soient bien plaqués au mur. Il y en a trois ou deux qui touchent le mur, les autres étant dans le vide, non plaqués, parfois arrêtés par un côté de la boîte d'encastrement en saillie.As a result, it is very rare that the four angles of the electrical device, which serve as a stop, are properly pressed against the wall. There are three or two of them touching the wall, the others being in a vacuum, unplated, sometimes stopped by one side of the protruding installation box.
De plus, il est toujours difficile, pour l'électricien, de mettre en place l'appareil électrique dans la boîte d'encastrement encombrée par l'arrivée et le retour de fils électriques qui occupent l'emplacement réservé à l'appareil ou qui s'interposent entre les accroches de l'appareil électrique et la boîte d'encastrement.In addition, it is always difficult for the electrician to set up the electrical appliance in the encumbered installation box by the arrival and return of electrical wires which occupy the space reserved for the appliance or which come between the hooks of the electrical appliance and the flush-mounting box.
L'électricien, étant tenu de respecter la verticalité de la pose de l'appareil électrique et de l'enjoliveur, est obligé d'enfoncer l'appareil électrique avec force dans l'espace qui lui était réservé, en déplaçant difficilement les fils, ou à défaut, en les coinçant malencontreusement entre les agrafes d'accrochage et la boîte d'encastrement. Il y a donc des efforts à fournir et une perte de temps. Autrefois, pour avoir une jonction parfaite entre le mur et une prise de courant, ou un interrupteur en saillie, on interposait une plaque de bois plane et isolante que l'on enduisait et peignait. Ensuite, on vissait, sur l'appareil, un enjoliveur obligatoirement bombé. Le pas de vis de l'enjoliveur était sur sa face périphérique intérieure et le bord de l'enjoliveur venait buter contre la plaque de bois.The electrician, being required to respect the verticality of the installation of the electrical appliance and the hubcap, is forced to forcefully insert the electrical appliance into the space reserved for him, with difficulty moving the wires, or failing that, by accidentally wedging them between the hooking clips and the flush-mounting box. There is therefore an effort to be made and a waste of time. Formerly, to have a perfect junction between the wall and an outlet, or a protruding switch, one interposed a flat and insulating wooden plate which one coated and painted. Then we screwed onto the device, a necessarily domed hubcap. The thread of the hubcap was on its inner peripheral face and the edge of the hubcap abutted against the wooden plate.
Actuellement, les solutions proposées ne répondent pas bien ou partiellement aux problèmes de mise en oeuvre vus ci-dessus. Il est clair que les appareils de forme carrée, s'emboîtant dans des boîtes d'encastrement carrées ou rondes, ne suffisent pas pour une bonne finition.Currently, the solutions proposed do not respond well or partially to the implementation problems seen above. It is clear that square-shaped devices, fitting into square or round flush-mounting boxes, are not enough for a good finish.
Les enjoliveurs ont tous l'appareil électrique comme butée et non pas le mur.The hubcaps all have the electrical appliance as a stop and not the wall.
L'état de la technique peut être défini par les documents suivants.State of the art can be defined by documents following.
La demande de brevet FR-A-2.641.652 a pour objet une boîte du genre comportant , monté mobile clrculalrement , un anneau qui, pour la fixation d ' un appareil à fixation par vis, présente, localement , au moins un logement taraudé propre à l 'Implantation d ' une telle vis. Suivant l 'Invention, cet anneau présente, en outre , localement , pour la fixation d ' un appareil à fixation par griffes , au moins une plage d 'appui propre à l 'Intervention d ' une telle griffe. La demande de brevet FR-A-2.678.118 propose un dispositif de fixation qui est adapté à être, au moins partiellement , emboîté à la manière d 'un couvercle dans une boîte d ' encastrement à fixer, et qui est équipé de moyens mécaniques propres à en permettre l 'assujettissement à la boîte d 'encastrement et de moyens magnétiques propres à permettre l 'adhérence de l ' ensemble à une hanche métallique. Les moyens mécaniques, dont est équipé ce dispositif de fixation, comportent au moins un verrou, du type verrou à quart de tour.The patent application FR-A-2,641,652 relates to a box of the type comprising, mounted movable clrculalrement, a ring which, for the fixing of a device with screw fixing, locally has at least one clean threaded housing to the implantation of such a screw. According to the invention, this ring also has, locally, for the attachment of an appliance with claw fixing, at least one bearing area specific to the intervention of such a claw. Patent application FR-A-2,678,118 proposes a fixing device which is adapted to be, at least partially, fitted in the manner of a cover in a recessed box to be fixed, and which is equipped with mechanical means suitable for allowing it to be secured to the installation box and magnetic means suitable for allowing the assembly to adhere to a metal hip. The mechanical means, with which this fixing device is fitted, comprise at least one lock, of the quarter-turn lock type.
Ces deux documents résolvent le problème de planéité de l'interrupteur uniquement dans le cas des murs banchés. Ils sont onéreux à l'investissement avec l'achat des aimants, et la boîte d'encastrement est en deux parties d'où une complication de la mise en oeuvre.These two documents solve the problem of flatness of the switch only in the case of tiled walls. They are expensive to invest with the purchase of magnets, and the mounting box is in two parts hence a complication of the implementation.
En cas de problème pour enfoncer l'appareil électrique dans la boîte d'encastrement, encombrée de fils, l'électricien n'a que la possibilité de faire une rotation de l'appareil électrique de 180', très limitée et pas souvent facile.In the event of a problem inserting the electrical appliance into the recessed box, cluttered with wires, the electrician only has the possibility of rotating the electrical appliance by 180 ', very limited and not often easy.
Le document BE-A-687.103 a pour objet un dispositif pour la fixation de plaques de recouvrement à des appareils encastrés pour Installations électriques , comportant des organes d ' assemblage élastiques fixés à la plaque de recouvrement et engagés avec effet de blocage automatique dans le corps .Document BE-A-687.103 relates to a device for fixing cover plates to built-in appliances for electrical installations, comprising elastic assembly members fixed to the cover plate and engaged with automatic blocking effect in the body .
Le document FR-A-1.559.002 propose une fixation sur la platine d ' un appareil électrique d 'un plaque d ' enjolivure dont la face Intérieure au moins est Isolante et qui est munie du côté Intérieur d 'au moins deux tétons constitués , au moins en partie, de matière Isolante élastique, dont la fixation à ladite plaque n 'est pas visible du côté extérieur. Ladite platine présente des trous associés aux tétons , ayant un diamètre un peu Inférieur à celui de ces derniers .The document FR-A-1.559.002 proposes a fixing on the plate of an electrical appliance with a trim plate whose interior face at least is insulating and which is provided on the interior side with at least two studs made up, at least in part, of elastic insulating material, the attachment to said plate is not visible from the outside. Said plate has holes associated with the nipples, having a diameter slightly less than that of these.
Ces deux documents mettent en oeuvre des dispositifs qui facilitent la mise en place. Néanmoins, la fixation de l'enjoliveur extérieur contre le mur n'est pas assurée. Des espaces peuvent être présents, ce qui peut altérer l'esthétisme et le bon fonctionnement de tels dispositifs. De plus, la sécurité n'est pas, dans le cas d'espaces trop importants, assurée. La présente invention apporte plusieurs solutions. La jonction entre l'enjoliveur et le mur est meilleure quand le mur sert lui-même de butée audit enjoliveur.These two documents implement devices which facilitate the installation. However, the fixing of the outer cover against the wall is not ensured. Spaces may be present, which can alter the aesthetics and the proper functioning of such devices. In addition, security is not ensured in the case of excessively large spaces. The present invention provides several solutions. The junction between the hubcap and the wall is better when the wall itself serves as a stop for said hubcap.
Le système de vissage de l'enjoliveur en périphérie permet une fixation plus stable et plus solide. Il peut également être clipé avec toujours le mur comme butée.The screwing system of the hubcap at the periphery allows a more stable and solid fixing. It can also be clipped with the wall always as a stop.
Cette fixation est stable et solide car elle se fait par trois points.This fixation is stable and solid because it is done by three points.
La forme ronde de l'enjoliveur augmente la performance technique, en l'occurrence la finition entre le mur et l'enjoliveur. En effet, lors d'une jonction imparfaite, les angles saillants d'un carré augmentent les défauts d'entrebâillement au fur et à mesure qu'ils s'éloignent de la périphérie de la boîte d'encastrement. Pour le rond, les éloignements du centre sont minima et uniformément répartis. Les entrebâillements, s'il y a, sont alors minimisés. Cette forme ronde, plate, en rapport avec sa fonction, est d'autant plus intéressante qu'elle apporte un nouveau style.The round shape of the cover increases the technical performance, in this case the finish between the wall and the cover. Indeed, during an imperfect junction, the salient angles of a square increase the cracking faults as they move away from the periphery of the mounting box. For the circle, the distances from the center are minimal and uniformly distributed. The gaps, if any, are then minimized. This round, flat shape, related to its function, is all the more interesting as it brings a new style.
Dans le cas particulier d'un bouton-poussoir rond, la mise en place de l'appareil électrique dans la boîte d'encastrement devient facile pour l'électricien qui n'a plus de verticalité de pose à respecter. Il peut donc éviter les fils électriques mal placés en choisissant l'angle de pose qui lui convient le mieux. De même que précédemment, l'enjoliveur n'a pas de verticalité à respecter.In the particular case of a round push button, the installation of the electrical device in the recessed box becomes easy for the electrician who no longer has vertical installation to respect. He can therefore avoid misplaced electrical wires by choosing the installation angle that best suits him. As before, the hubcap has no verticality to respect.
A cet effet, la présente invention concerne un procédé de calage et de fixation d'un dispositif électrique encastré, contenant une prise de courant ou un interrupteur électrique, ou autres, caractérisé en ce qu'il consiste à effectuer les étapes successives suivantes : réalisation d'une cavité murale au niveau où l'appareil électrique doit être implanté, - scellement d'une boîte d'encastrement, dans laquelle arrivent les câblages électriques,To this end, the present invention relates to a method of wedging and fixing a built-in electrical device, containing a socket or an electrical switch, or the like, characterized in that it consists in carrying out the following successive steps: production a wall cavity at the level where the electrical appliance is to be installed, - sealing of a flush-mounting box, into which the electrical cables arrive,
- connexion des câblages avec 1*appareil électrique proprement dit, - fixation dudit appareil électrique, vis-à-vis de la boîte d'encastrement, par l'intermédiaire d'une plaque de fixation, située contre la surface d'implantation, telle qu'un mur, à l'extérieur de la cavité, et fixation d'un enjoliveur sur la plaque de fixation, qui s'effectue en trois points distincts, par un complet recouvrement de ladite plaque, l'enjoliveur s'adaptant exactement à la surface extérieure du mur où il est implanté.- connection of the cables with the electrical appliance proper, - fixing of said electrical appliance, vis-à-vis the flush-mounting box, by means of a fixing plate, situated against the implantation surface, such that a wall, outside the cavity, and fixing of a cover on the fixing plate, which is carried out at three distinct points, by a complete covering of said plate, the cover fitting exactly the exterior surface of the wall where it is installed.
Selon un mode de réalisation, la fixation de l'enjoliveur, par rapport à la plaque de fixation, s'effectue par vissage. Selon un autre mode de réalisation, la fixation de l'enjoliveur, par rapport à la plaque de fixation, s'effectue par clipage.According to one embodiment, the fixing of the hubcap, relative to the fixing plate, is carried out by screwing. According to another embodiment, the fixing of the hubcap, relative to the fixing plate, is carried out by clipping.
La présente invention concerne également un dispositif électrique, comportant un appareil électrique encastré, tel qu'une prise de courant ou un interrupteur électrique, qui est monté par l'intermédiaire du procédé précédent, caractérisée par le fait qu'il est constitué par une boîte d'encastrement, l'appareil électrique, solidaire d'une plaque de fixation et un enjoliveur extérieur. La plaque de fixation comporte trois bras dont chaque extrémité libre comporte un retour qui constitue un moyen de fixation pour un moyen de fixation de l'enjoliveur, de forme complémentaire, et trois plots élastiques d'appui contre le mur.The present invention also relates to an electrical device, comprising a built-in electrical device, such as an electrical outlet or an electrical switch, which is mounted by means of the preceding method, characterized in that it consists of a box the electrical appliance, secured to a fixing plate and an external cover. The fixing plate has three arms, each free end of which has a return which constitutes a fixing means for a fixing means for the hubcap, of complementary shape, and three elastic studs for bearing against the wall.

Les moyens de fixation sont constitués par un filetage des retours des trois bras de la plaque de fixation et par un taraudage périphérique de l'enjoliveur.The fixing means are constituted by a thread of the returns of the three arms of the fixing plate and by a peripheral thread of the hubcap.
La plaque de fixation et la boîte d'encastrement comportent des moyens de solidarisation réciproques.The fixing plate and the embedding box comprise reciprocal securing means.

La présente invention concerne un procédé de calage et de fixation d'un dispositif électrique 1 encastré contenant un appareil électrique 2, par exemple une prise de courant ou un interrupteur électrique 2, comme c'est le cas sur les figures 1,The present invention relates to a method of wedging and fixing an embedded electrical device 1 containing an electrical appliance 2, for example an electrical outlet or an electrical switch 2, as is the case in FIGS. 1,
2, 5 et 6.2, 5 and 6.
Autrefois, afin de permettre une bonne application des interrupteurs 18 contre les murs 10, il était nécessaire d'utiliser un tasseau ou plaque en bois 19, afin de ne pas créer de jour entre l'interrupteur 18 et le tasseau 19. Dans ce cas, l'interrupteur 18 était mis en contact avec le tasseau en bois 19 afin qu'il n'y ait aucun espace entre les deux éléments 18 et 19. Actuellement, on utilise des interrupteurs tels que ceux représentés aux figures 3 et 4. Ces interrupteurs comportent un bouton 17 qui nécessite un positionnement parfait, que ce soit contre le mur ou que ce soit en horizontalité et en verticalité.Formerly, in order to allow a good application of the switches 18 against the walls 10, it was necessary to use a cleat or wooden plate 19, so as not to create a day between the switch 18 and the cleat 19. In this case , the switch 18 was brought into contact with the wooden strip 19 so that there is no space between the two elements 18 and 19. Currently, switches such as those shown in Figures 3 and 4 are used. switches have a button 17 which requires perfect positioning, whether against the wall or whether horizontally and vertically.
De ce fait, il n'est pas toujours aisé, pour le monteur, de réaliser un boîtier d'encastrement qui soit parfaitement adapté à l'ensemble de ses nécessités. Ainsi, la fixation de l'enjoliveur de l'interrupteur 15 est assurée par des vis qui ne sont pas très esthétiques car elles sont généralement visibles, et vont se fixer contre le boîtier d'encastrement sous-jacent. De ce fait, l'enjoliveur de l'interrupteur 15 va venir en butée contre le mur. Si ce mur n'est pas parfaitement plan, il y a de nombreux espaces qui vont être créés entre l'interrupteur 15 et ledit mur. Pour résoudre ces problèmes, le procédé consiste à effectuer les différentes étapes successives suivantes.As a result, it is not always easy for the fitter to produce a recessed box which is perfectly suited to all of his needs. Thus, the fixing of the cover of the switch 15 is ensured by screws which are not very aesthetic because they are generally visible, and will be fixed against the underlying embedding box. Therefore, the cover of the switch 15 will abut against the wall. If this wall is not perfectly flat, there are many spaces that will be created between the switch 15 and said wall. To solve these problems, the method consists in carrying out the following successive stages.
Tout d'abord, il y a réalisation, comme on le voit sur la figure 1, d'une cavité murale 12 au niveau où l'appareil électrique 2 doit être implanté. Bien entendu, si l'on désire implanter l'appareil électrique 2 à un autre endroit, il sera possible de le fixer au niveau du sol, au niveau du plafond ou sur tout support plan.First of all, there is an embodiment, as can be seen in FIG. 1, of a wall cavity 12 at the level where the electrical appliance 2 must be installed. Of course, if it is desired to locate the electrical appliance 2 at another location, it will be possible to fix it at ground level, at ceiling level or on any flat support.
Ensuite, la boîte d'encastrement 3 est scellée par un scellement 13, par exemple en plâtre ou en béton. Cette boîte d'encastrement 3 reçoit un certain nombre de câblages électriquesThen, the embedding box 3 is sealed by a seal 13, for example plaster or concrete. This installation box 3 receives a certain number of electrical cables
14 qui vont permettre à l'appareil électrique ou interrupteur 2 d'être alimenté et de fonctionner.14 which will allow the electrical appliance or switch 2 to be supplied and to operate.
L'étape suivante consiste en la connexion des câblages 14 précédents avec l'appareil électrique 2 proprement dit. Ensuite, il y a nécessité de fixer l'appareil électrique 2 vis-à-vis de la boîte d'encastrement 3 par l'intermédiaire d'une plaque de fixation 4 qui est située contre la surface d'implantation, c'est-à-dire contre le mur 10. En fait, et comme on le comprend bien, cette plaque de fixation 4 va venir en butée contre le mur 10.The next step is to connect the previous wiring 14 with the electrical device 2 itself. Then there is a need to fix the electrical appliance 2 vis-à-vis the flush-mounting box 3 by means of a fixing plate 4 which is situated against the implantation surface, that is to say that is to say against the wall 10. In fact, and as is well understood, this fixing plate 4 will come into abutment against the wall 10.
Dans le mode particulier de réalisation présenté sur la figure 1, la plaque 4 comporte des plots élastiques d'appui 9 qui adaptent la position de ladite plaque 4 à la forme du mur 10 avoisinant. Bien entendu, l'appareil électrique 2 est solidarisé à la plaque de fixation 4 par tout moyen de l'état de la technique.In the particular embodiment presented in FIG. 1, the plate 4 comprises elastic support pads 9 which adapt the position of said plate 4 to the shape of the neighboring wall 10. Of course, the electrical device 2 is secured to the fixing plate 4 by any means of the prior art.
En ce qui concerne la fixation de l'ensemble constitué par la plaque de fixation 4 et l'appareil électrique 2 vis-à-vis de la boîte d'encastrement 3, ladite boîte 3 comporte des éléments taraudés pouvant chacun recevoir une vis. Les éléments taraudés et les vis constituent les moyens de solidarisation 11.As regards the fixing of the assembly constituted by the fixing plate 4 and the electrical appliance 2 with respect to the embedding box 3, said box 3 comprises tapped elements which can each receive a screw. The threaded elements and the screws constitute the securing means 11.
La dernière étape de ce procédé consiste en la fixation d'un enjoliveur 5 sur la plaque de fixation 4. Comme la plaque 4 a été positionnée au plus près et dans les meilleures conditions vis-à- vis de la surface extérieure du mur 10, l'enjoliveur 5 va donc venir se positionner de façon adéquate vis-à-vis dudit mur 10. Ledit enjoliveur 5 va recouvrir complètement ladite plaque 4 en s'adaptant exactement à la surface extérieure du mur 10, où il est implanté, et ce quelle que soit la planéité de la surface extérieure dudit mur 10.The last step of this process consists in attaching a cover 5 to the fixing plate 4. As the plate 4 has been positioned as close as possible and in the best possible conditions vis the outer surface of the wall 10, the cover 5 will therefore come to position itself adequately with respect to said wall 10. Said cover 5 will completely cover said plate 4 by adapting exactly to the external surface of the wall 10, where it is located, regardless of the flatness of the exterior surface of said wall 10.
Dans le mode de réalisation de l'invention qui est présenté sur les figures, et que l'on voit mieux représenté sur la figure 2, la fixation de l'enjoliveur 5 par rapport à la plaque de fixation 3 s'effectue en trois points distincts.In the embodiment of the invention which is presented in the figures, and which can be seen better represented in FIG. 2, the fixing of the hubcap 5 relative to the fixing plate 3 is carried out at three points separate.
Sur les figures, cette fixation s'effectue par vissage, mais on pourrait tout aussi bien avoir de bons résultats avec un système par clipage.In the figures, this fixing is done by screwing, but we could just as well have good results with a system by clipping.
Dans le mode de réalisation de la figure 2, le dispositif électrique 1 est donc constitué par une boîte d'encastrement 3, l'appareil électrique 2, solidaire d'une plaque de fixation 4, et un enjoliveur extérieur 5.In the embodiment of FIG. 2, the electrical device 1 is therefore constituted by a mounting box 3, the electrical device 2, secured to a fixing plate 4, and an external cover 5.
La plaque de fixation 4 comporte trois bras 6 dont chaque extrémité libre comporte un retour 7, qui constitue un moyen de fixation 7 pour un moyen de fixation 8 de l'enjoliveur 5,de forme complémentaire. En fait, l'appareil électrique 2, associé à la plaque de fixation 4, se cale sur le mur 10, à l'aide des trois plots élastiques d'appui 9 portés par les trois bras 6, ayant des retours filetés 7 à leur extrémité périphérique, chaque bras 6 étant espacé de 120', ce qui permet à l'enjoliveur extérieur 5 d'être vissé avec une assise maximale contre le mur 10.The fixing plate 4 has three arms 6, each free end of which has a return 7, which constitutes a fixing means 7 for a fixing means 8 of the hubcap 5, of complementary shape. In fact, the electrical appliance 2, associated with the fixing plate 4, is wedged on the wall 10, using the three elastic support pads 9 carried by the three arms 6, having threaded returns 7 at their peripheral end, each arm 6 being spaced 120 ′ apart, which allows the outer cover 5 to be screwed with a maximum seat against the wall 10.
Les plots élastiques 9, permettant la bonne stabilisation de l'ensemble contre ledit mur 10, étant au nombre de trois, cela permet à tous les plots 9 d'être en contact avec ledit mur 10. Les moyens de fixation 7 et 8 sont donc constitués par un filetage 7 des retours des trois bras 6 de la plaque de fixation 4 et par un taraudage périphérique 8 de l'enjoliveur extérieur 5, le filetage 7 et le taraudage 8 coopérant ensemble.The elastic studs 9, allowing good stabilization of the assembly against said wall 10, being three in number, this allows all the studs 9 to be in contact with said wall 10. The fixing means 7 and 8 are therefore constituted by a thread 7 of the returns of the three arms 6 of the fixing plate 4 and by a peripheral thread 8 of the outer trim 5, the thread 7 and the thread 8 cooperating together.
La plaque de fixation 4 et la boîte d'encastrement 3 sont, comme on l'a vu pour le procédé, réunies à l'aide de moyens de solidarisation réciproques 11.The fixing plate 4 and the embedding box 3 are, as we have seen for the process, joined together by means of reciprocal securing means 11.
Comme on le voit bien sur les figures 5 et 6, dans un mode de réalisation préférentiel de l'invention, la forme extérieure de l'enjoliveur 5 est ronde, ce qui ne nécessite aucun réglage quant à l'horizontalité et à la verticalité de l'interrupteur 2. Une telle invention permet un bon calage de l'enjoliveur 5 quelle que soit la planéité du mur, où la boite d'encastrement 3 est scellée, mais permet également à l'électricien de travailler plus aisément sans être tenu de respecter la verticalité de la pose de l'appareil électrique 2 encastré, ainsi que de l'enjoliveur 5.As can be seen in Figures 5 and 6, in a preferred embodiment of the invention, the outer shape of the hubcap 5 is round, which requires no adjustment as for the horizontality and the verticality of the switch 2. Such an invention allows a good setting of the hubcap 5 whatever the flatness of the wall, where the mounting box 3 is sealed, but also allows the electrician to work more easily without being required to respect the verticality of the installation of the built-in electrical appliance 2, as well as of the hubcap 5.
De plus, le bouton 16 de l'interrupteur 2 est rond, ce qui facilite encore plus le positionnement. Bien entendu, ce mode de réalisation de l'interrupteur 2 n'est pas absolument nécessaire ; on pourrait tout aussi bien utiliser des interrupteurs de type classique, tels que ceux représentés aux figures 3 et 4, il suffit pour cela que l'intérieur de l'enjoliveur de l'interrupteur 15 comporte un taraudage périphérique 8 identique à celui de la figure 1. Dans ce cas, il sera aisé de régler la verticalité de l'interrupteur 15 en jouant sur l'épaisseur des plots élastiques d'appui 9, en augmentant ou en diminuant leur compression par actionnement des moyens de solidarisation 11. Ainsi, plus les moyens de solidarisation 11 seront vissés, plus la plaque 4 sera rapprochée du mur et ainsi en est-il également du rapprochement de l'enjoliveur extérieur dudit interrupteur 15.In addition, the button 16 of the switch 2 is round, which further facilitates positioning. Of course, this embodiment of the switch 2 is not absolutely necessary; one could just as well use switches of conventional type, such as those represented in FIGS. 3 and 4, it suffices for this that the interior of the trim of the switch 15 includes a peripheral thread 8 identical to that of FIG. 1. In this case, it will be easy to adjust the verticality of the switch 15 by varying the thickness of the elastic support pads 9, by increasing or decreasing their compression by actuation of the securing means 11. Thus, more the fastening means 11 will be screwed, the closer the plate 4 will be to the wall and so also the approximation of the outer cover of said switch 15.
Selon un mode particulier de réalisation, la plaque 4 et le boîtier 2 forment une seule et même pièce. According to a particular embodiment, the plate 4 and the housing 2 form a single piece.
