Description

DOMAINE TECHNIQUE AUQUEL SE RAPPORTE L'INVENTIONTECHNICAL FIELD TO WHICH THE INVENTION REFERS

La présente invention concerne de manière générale les prises électriques.The present invention relates generally to electrical outlets.

Elle concerne plus particulièrement une prise électrique conforme au préambule de la revendication 1.It relates more particularly to an electrical outlet according to the preamble of claim 1.

L'invention permet la réalisation de prises électriques de tout standard, notamment de prises électriques conformes au standard « shuko », également connu sous la référence CEE 7/4, ou au standard franco-belge, comprenant un volet de protection mobile.The invention allows the production of electrical outlets of any standard, including electrical plugs conforming to the "shuko" standard, also known as CEE 7/4, or the Franco-Belgian standard, including a movable protective cover.

ARRIÈRE-PLAN TECHNOLOGIQUETECHNOLOGICAL BACKGROUND

On connaît déjà notamment du document FR2886775 , une telle prise électrique dans laquelle l'obturateur est monté fixement à l'extrémité du montant central. Le montant central et l'obturateur sont ainsi solidaires en pivotement autour d'un axe longitudinal dudit montant central.We already know in particular from the document FR2886775 such an electrical outlet in which the shutter is fixedly mounted to the end of the central upright. The central upright and the shutter are thus integral in pivoting about a longitudinal axis of said central upright.

Dans ces conditions, lorsque les broches d'une fiche électrique sont insérées dans les orifices du volet, l'obturateur pivote de sa position d'obturation vers sa position d'ouverture sous la pression de ces broches.Under these conditions, when the pins of an electrical plug are inserted into the orifices of the flap, the shutter pivots from its closed position to its open position under the pressure of these pins.

Le montant central pivote en conséquence d'une position angulaire de verrouillage dans laquelle il bloque la translation du volet dans le puits de la prise à une position angulaire de coulissement dans laquelle le montant central coulisse conjointement avec le volet.The central post pivots accordingly to a locking angular position in which it blocks the translation of the flap in the well of the socket at an angular sliding position in which the central upright slides in conjunction with the flap.

Dans cette position angulaire de coulissement, le montant central est adapté à coulisser depuis une position axiale haute correspondant à une position d'attente du volet, vers une position axiale basse dans laquelle la fiche électrique est complètement introduite dans le puits. En outre, le montant central est guidé par un élément de guidage qui interdit tout pivotement du montant central autour de son axe longitudinal.In this angular sliding position, the central upright is adapted to slide from a high axial position corresponding to a waiting position of the shutter, to a low axial position in which the electrical plug is completely inserted into the well. In addition, the central upright is guided by a guide element which prevents any pivoting of the central upright around its longitudinal axis.

En fonctionnement normal, lorsque la fiche est retirée de la prise, des moyens de rappel ramènent le montant central vers sa position axiale haute en le faisant coulisser vers l'avant de la prise électrique. Une fois arrivé dans sa position axiale haute, le montant central peut à nouveau pivoter autour de son axe longitudinal : des moyens de rappel de l'obturateur ramènent celui-ci vers sa position d'obturation. Ce faisant, l'obturateur entraîne le montant central, qui pivote en conséquence vers sa position angulaire de verrouillage.In normal operation, when the plug is removed from the socket, return means bring the central upright to its upper axial position by sliding it towards the front of the electrical socket. Once arrived in its high axial position, the central upright can again pivot about its longitudinal axis: shutter return means bring it to its closed position. In doing so, the shutter drives the central post, which pivots accordingly towards its locking angular position.

Lorsque l'utilisateur achève d'extraire les broches de la fiche électrique des ouvertures du volet qui les accueillent, l'obturateur passe ainsi automatiquement dans sa position d'obturation et les bornes de la prise électrique sont rendues inaccessibles à l'utilisateur.When the user completes extracting the pins of the electrical plug from the openings of the shutter that receives them, the shutter passes as well. automatically in its shutter position and the terminals of the electrical outlet are made inaccessible to the user.

La sécurité électrique de la prise électrique est ainsi assurée.The electrical safety of the electrical outlet is thus ensured.

Cependant, il peut arriver que l'utilisateur maintienne le volet dans sa position enfoncée en retirant la fiche de la prise, ou qu'un élément extérieur bloque le volet en position enfoncée alors que la fiche est retirée de la prise. Le montant central est alors dans sa position angulaire de coulissement, et n'est pas libre de pivoter autour de son axe longitudinal. Il empêche alors l'obturateur de pivoter vers sa position d'obturation et les bornes de connexion de la prise restent accessibles.However, it may happen that the user keeps the flap in its depressed position by removing the plug from the socket, or an external element blocks the flap in the depressed position while the plug is removed from the socket. The central upright is then in its angular sliding position, and is not free to pivot about its longitudinal axis. It then prevents the shutter from swiveling to its shutter position and the connection terminals of the socket remain accessible.

La sécurité électrique de la prise n'est donc plus assurée.The electrical safety of the socket is no longer assured.

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

Afin de remédier aux inconvénients précités de l'état de la technique, l'invention propose un nouveau type de prise, dans laquelle la sécurité électrique est renforcée.In order to overcome the aforementioned drawbacks of the state of the art, the invention proposes a new type of socket, in which electrical safety is enhanced.

A cet effet, on propose selon l'invention une prise électrique conforme à la revendication 1.For this purpose, there is provided according to the invention an electrical socket according to claim 1.

L'obturateur peut alors être ramené vers sa position d'obturation dès le retrait des broches de la fiche électrique hors de la prise, quelle que soit la position du montant central.The shutter can then be returned to its closed position as soon as the pins of the electrical plug are removed from the socket, regardless of the position of the central upright.

Dans les conditions de fonctionnement anormales de la prise électrique décrites précédemment, la sécurité électrique de la prise est alors assurée puisque l'accès aux bornes électriques de la prise est bloqué.In the abnormal operating conditions of the electrical outlet described above, the electrical safety of the socket is then ensured since access to the electrical terminals of the socket is blocked.

D'autres caractéristiques avantageuses et non limitatives de la prise électrique selon l'invention sont énoncées dans les revendications 2 à 14.Other advantageous and non-limiting characteristics of the electrical socket according to the invention are set forth in claims 2 to 14.

Dans la description, les termes « avant » et « arrière » désignent respectivement le côté de l'appareillage électrique orienté vers l'utilisateur lorsque cet appareillage est utilisé et le côté opposé.In the description, the terms "front" and "rear" respectively refer to the side of the electrical equipment facing the user when this equipment is used and the opposite side.

On a représenté sur les figures 1, 10 et 11, une prise électrique 700 comportant un puits adapté à recevoir une fiche électrique complémentaire pour le raccordement de cette fiche au réseau électrique.We have shown on figures 1 , 10 and 11 , an electrical outlet 700 having a well adapted to receive a complementary electrical plug for connecting this plug to the electrical network.

La prise électrique 700 est ici adaptée à être logée dans une boîte encastrée ou rapportée en saillie sur une paroi quelconque (non représentée). En variante, il peut s'agir d'une prise électrique du type rallonge ou d'un bloc multiprises. Le principe de l'invention décrit ici n'est alors pas modifié.Electrical socket 700 is here adapted to be housed in a recessed box or reported projecting on any wall (not shown). Alternatively, it may be an outlet type extension or a power strip. The principle of the invention described here is not modified.

Comme le montrent les figures 1, 4, 5, et 8 à 11, les différents éléments internes de la prise électrique 700 sont logés dans un socle 100. Ce socle 100 est réalisé en matière isolante, par exemple par moulage d'une matière plastique.As shown by figures 1 , 4 , 5 , and 8 to 11 , the various internal elements of the socket 700 are housed in a base 100. This base 100 is made of insulating material, for example by molding a plastic material.

Le socle 100 présente une forme globalement parallélépipédique (figures 1, 5, 9, 10 et 11). Ce socle 100 est ouvert en face avant.The base 100 has a generally parallelepipedal shape ( figures 1 , 5 , 9 , 10 and 11 ). This base 100 is open on the front face.

Il comporte un fond 111 bordé d'une paroi latérale 112 présentant quatre pans deux à deux opposés qui s'élèvent à partir du fond 111, sensiblement perpendiculairement à celle-ci (voir notamment figures 5 et 9).It comprises a bottom 111 bordered by a side wall 112 having four opposite two-sided panels which rise from the bottom 111, substantially perpendicular thereto (see in particular figures 5 and 9 ).

Un épaulement 121 de la paroi latérale 112 induit un élargissement de la section du socle 100 (figures 5 et 9).A shoulder 121 of the side wall 112 induces an enlargement of the section of the base 100 ( figures 5 and 9 ).

Cet épaulement 121 est situé à la frontière entre une partie arrière 110 et une partie avant 120 du socle 100.This shoulder 121 is located at the boundary between a rear portion 110 and a front portion 120 of the base 100.

Une plaquette 200 isolante (figures 1, 4 et 8) repose sur l'épaulement 121 de manière à former un fond intermédiaire du socle 100 et à fermer vers l'avant la partie arrière 110 du socle 100.An insulating wafer 200 ( figures 1 , 4 and 8 ) rests on the shoulder 121 so as to form an intermediate bottom of the base 100 and to close forwards the rear portion 110 of the base 100.

Cette plaquette 200 comporte une partie plane 201 rectangulaire qui s'étend sensiblement parallèlement au fond 111 du socle 100. Elle comporte à chacun de ses angles un crochet anti-arrachement 204 dont une portion s'étend perpendiculairement à ladite partie plane 201 de la plaquette 200 et coopère à retenue avec la paroi latérale 112 du socle 100 pour empêcher tout déplacement vers l'avant de la plaquette 200.This wafer 200 comprises a rectangular flat portion 201 which extends substantially parallel to the bottom 111 of the base 100. It comprises at each of its corners an anti-tearing hook 204, a portion extending perpendicularly to said flat portion 201 of the wafer 200 and cooperates with retaining the side wall 112 of the base 100 to prevent forward movement of the wafer 200.

La plaquette 200 reposant par ailleurs sur l'épaulement 121, tout mouvement de cette plaquette vers l'arrière est bloqué.The plate 200 resting on the shoulder 121, any movement of this plate back is blocked.

Comme le montrent les figures 1, 4, 5, 8 et 9, la partie avant 120 du socle 100 comporte des moyens de montage de ce socle dans un support de mécanisme d'appareillage électrique (non représenté). Ce support se présente typiquement sous la forme d'un cadre comportant une ouverture centrale à travers laquelle passe le socle 100.As shown by figures 1 , 4 , 5 , 8 and 9 , the front portion 120 of the base 100 comprises means for mounting the base in a gear mechanism mechanism (not shown). This support is typically in the form of a frame having a central opening through which the base 100 passes.

Plus précisément, le socle 100 comporte un trottoir 123 longeant le bord de l'ouverture avant du socle 100 et des moyens d'encliquetage 125 ménagés dans sa paroi latérale 112.More specifically, the base 100 includes a sidewalk 123 along the edge of the front opening of the base 100 and latching means 125 formed in its side wall 112.

Lorsque le trottoir 123 vient s'appuyer sur une face avant du support, les moyens d'encliquetage 125 s'accrochent à l'arrière du support.When the sidewalk 123 comes to rest on a front face of the support, the latching means 125 cling to the rear of the support.

Le support peut ensuite être appliqué contre la paroi sur laquelle la prise électrique 100 est destinée à être montée.The support can then be applied against the wall on which the electrical outlet 100 is intended to be mounted.

Le socle 100 loge en outre des éléments de contact électrique permettant de connecter la fiche électrique insérée dans la prise électrique au réseau électrique.The base 100 furthermore houses electrical contact elements making it possible to connect the electrical plug inserted in the electrical outlet to the electrical network.

Ces éléments de contact électrique comprennent trois bornes de connexion.These electrical contact elements comprise three terminals of connection.

Il est prévu une borne de connexion de phase B1 et une borne de connexion de neutre B2 (figures 4 et 8) logées dans la partie arrière 110 du socle 100 ainsi qu'une borne de connexion reliée à la terre, chacune connectée électriquement à un conducteur électrique du réseau électrique acheminant le courant de phase, de neutre ou relié à la terre.There is a phase connection terminal B1 and a neutral connection terminal B2 ( figures 4 and 8 ) housed in the rear portion 110 of the base 100 and a connection terminal connected to the ground, each electrically connected to an electrical conductor of the electrical network carrying the phase current, neutral or earthed.

Chaque borne de phase B1 et de neutre B2 comporte en particulier un alvéole de réception situé en regard d'une ouverture circulaire 202 de la plaquette 200 et adapté à recevoir l'une des broches de phase et de neutre de la fiche électrique correspondante (figures 4 et 8).Each phase terminal B1 and neutral B2 comprises in particular a receiving cell located opposite a circular opening 202 of the wafer 200 and adapted to receive one of the phase and neutral pins of the corresponding electrical plug ( figures 4 and 8 ).

Lorsque la fiche est insérée dans la prise électrique 700, les broches de cette fiche traversent ainsi les ouvertures circulaires 202 de la plaquette 200 et pénètrent dans les alvéoles de réception des bornes de connexion de phase B1 et de neutre B2.When the plug is inserted into the electrical outlet 700, the pins of this plug thus pass through the circular openings 202 of the wafer 200 and penetrate into the receiving cells of the phase connection terminals B1 and neutral B2.

La borne de connexion reliée à la terre représentée sur les figures est une borne conforme au standard « shuko » germanique. Elle comporte ainsi ici une lame métallique repliée en U formant une lyre 210, représentée sur la figure 11.The connection terminal connected to the earth shown in the figures is a terminal conforming to the standard "shuko" Germanic. It thus comprises here a metal blade folded U forming a lyre 210, shown on the figure 11 .

En variante, la borne de connexion reliée à la terre peut également être conforme à un autre standard, par exemple au standard franco-belge.Alternatively, the grounded connection terminal may also be in accordance with another standard, for example the Franco-Belgian standard.

La partie avant 120 du socle 100 de la prise électrique 700 loge une paroi cylindrique 400 délimitant le puits d'accueil de la fiche électrique complémentaire (figure 1).The front portion 120 of the base 100 of the electrical outlet 700 houses a cylindrical wall 400 delimiting the receiving well of the complementary electrical plug ( figure 1 ).

Cette paroi cylindrique 400 est montée sur la paroi latérale 112 de la partie avant 120 du socle 100 (figure 1).This cylindrical wall 400 is mounted on the side wall 112 of the front portion 120 of the base 100 ( figure 1 ).

Elle comporte notamment, pour son accrochage sur le socle 100, en saillie de sa face externe 403 (figure 1), au moins deux dents d'accrochage 402 diamétralement opposées qui son reçues dans des logements complémentaires de la paroi latérale 112 de la partie avant 120 du socle 100.It includes in particular, for its attachment on the base 100, projecting from its outer face 403 ( figure 1 ), at least two diametrically opposed coupling teeth 402 received in complementary housings of the side wall 112 of the front portion 120 of the base 100.

Le bord avant 404 (figure 1) de la paroi cylindrique 400 forme un rebord en saillie de la paroi cylindrique, vers l'extérieur du puits. Ce rebord prend appui sur le bord avant de la partie avant 120 du socle 100.The front edge 404 ( figure 1 ) of the cylindrical wall 400 forms a flange projecting from the cylindrical wall, outwardly of the well. This flange is supported on the front edge of the front portion 120 of the base 100.

Cette paroi cylindrique 400 accueille deux montants latéraux 410 prévus face à face, s'étendant en saillie d'une face interne 401 de cette paroi cylindrique 400 parallèlement à l'axe longitudinal X de celle-ci (figures 1 et 11).This cylindrical wall 400 accommodates two lateral uprights 410 provided face to face, projecting from an inner face 401 of this cylindrical wall 400 parallel to the longitudinal axis X thereof ( figures 1 and 11 ).

Les montants latéraux 410 sont diamétralement opposés dans le puits de la prise électrique 700 et sont adaptés à guider le coulissement de la fiche électrique complémentaire dans la prise électrique lors de son insertion.The lateral amounts 410 are diametrically opposed in the well of electrical outlet 700 and are adapted to guide the sliding of the complementary electrical plug into the electrical outlet during its insertion.

En variante on peut prévoir un nombre quelconque de montants latéraux.Alternatively, any number of side posts can be provided.

La face interne 401 de la paroi cylindrique 400 comporte ici deux rainures 405 (figures 1 et 11) au travers desquelles les branches latérales de la lyre 210 font saillie à l'intérieur du puits de la prise électrique 700. Ces deux rainures 405 sont diamétralement opposées selon un diamètre orienté à 90 degrés par rapport au diamètre selon lequel les montants latéraux sont alignés.The internal face 401 of the cylindrical wall 400 here comprises two grooves 405 ( figures 1 and 11 ) through which the lateral branches of the lyre 210 protrude inside the well of the electrical socket 700. These two grooves 405 are diametrically opposed in a diameter oriented at 90 degrees with respect to the diameter according to which the lateral uprights are aligned. .

Un volet 600 obturant la section du puits est monté mobile en translation par rapport à ladite paroi cylindrique 400 le long de l'axe longitudinal X de celle-ci, entre deux positions extrêmes (figures 1, 10 et 11).A shutter 600 closing the section of the well is mounted mobile in translation relative to said cylindrical wall 400 along the longitudinal axis X thereof, between two extreme positions ( figures 1 , 10 and 11 ).

Ce volet 600 comporte une paroi principale 601 de contour globalement circulaire.This flap 600 comprises a main wall 601 of generally circular contour.

Le contour de la paroi principale 601 du volet 600 comporte ici deux découpes 603 diamétralement opposées pour le passage des branches latérales de la lyre 210 ainsi que des encoches à angle droit adaptées au passage des montants latéraux 410 lors de la translation du volet 600 (figures 1, 10 et 11).The outline of the main wall 601 of the flap 600 here comprises two diametrically opposed cutouts 603 for the passage of the lateral branches of the lyre 210 as well as notches at right angles adapted to the passage of the lateral uprights 410 during the translation of the shutter 600 ( figures 1 , 10 and 11 ).

En variante, si la prise électrique est conforme à un standard différent, le volet comporte des ouvertures appropriées au passage des éléments de connexion électrique reliés à la terre, par exemple une ouverture laissant passer une broche de terre dans le standard franco-belge, en remplacement des découpes 603.Alternatively, if the electrical outlet is in accordance with a different standard, the flap has openings suitable for the passage of grounded electrical connection elements, for example an opening allowing a ground pin to pass through the French-Belgian standard, in replacement of cuts 603.

La paroi principale 601 du volet 600 comporte également deux orifices circulaires 604 dont les dimensions et les positions sont adaptées au passage des broches de la fiche électrique complémentaire destinée à être insérée dans la prise électrique 700.The main wall 601 of the shutter 600 also has two circular orifices 604 whose dimensions and positions are adapted to the passage of the pins of the complementary electrical plug to be inserted into the socket 700.

Cette paroi principale 601 est partiellement entourée d'une paroi tombante 602 orientée vers l'arrière de la prise électrique 700 (figure 1).This main wall 601 is partially surrounded by a falling wall 602 directed towards the rear of the electrical socket 700 ( figure 1 ).

Cette paroi tombante 602 s'applique contre la face interne 401 de la paroi cylindrique 400 et guide la translation du volet 600 contre cette paroi cylindrique.This falling wall 602 is applied against the inner face 401 of the cylindrical wall 400 and guides the translation of the flap 600 against this cylindrical wall.

Les positions extrêmes du volet 600 sont représentées sur les figures 10 et 11.The extreme positions of the shutter 600 are represented on the Figures 10 and 11 .

Dans l'une de ces positions extrêmes, appelée dans la suite position enfoncée et représentée sur la figure 11, le volet 600 s'étend en retrait du bord avant de la paroi cylindrique 400.In one of these extreme positions, hereinafter referred to as the depressed position and shown on the figure 11 , the flap 600 extends back from the front edge of the cylindrical wall 400.

Dans cette position enfoncée, les orifices circulaires 604 du volet 600 s'étendent à proximité des ouvertures circulaires 202 de la plaquette 200. Les broches de la fiche électrique qui traversent les orifices circulaires 604 du volet 600 s'insèrent comme expliqué précédemment dans les ouvertures circulaires 202 de la plaquette 200 qui donnent accès aux bornes de connexion de phase et de neutre.In this depressed position, the circular orifices 604 of the flap 600 extend near the circular openings 202 of the wafer 200. The pins of the electrical plug which pass through the circular orifices 604 of the shutter 600 fit as explained previously in the openings 202 of the wafer 200 which provide access to the phase and neutral connection terminals.

Dans l'autre position extrême, appelée dans la suite position d'attente et représentée sur la figure 10, le volet 600 s'étend à proximité du bord avant 404 de ladite paroi cylindrique 400.In the other extreme position, called in the following position of waiting and represented on the figure 10 , the flap 600 extends near the front edge 404 of said cylindrical wall 400.

Plus précisément, dans la position d'attente, une face avant de la paroi principale 601 du volet 600 affleure le bord avant 404 de la paroi cylindrique ou dépasse légèrement vers l'avant de ce bord avant 404 (figure 10).More specifically, in the waiting position, a front face of the main wall 601 of the flap 600 is flush with the front edge 404 of the cylindrical wall or protrudes slightly towards the front of this front edge 404 ( figure 10 ).

La bord avant 404 de la paroi cylindrique 400 accueille ici un enjoliveur 130 (figures 10 et 11) qui entoure le bord avant 404 de la paroi cylindrique 400.The front edge 404 of the cylindrical wall 400 here accommodates a hubcap 130 ( Figures 10 and 11 ) which surrounds the front edge 404 of the cylindrical wall 400.

Dans sa position d'attente, la face avant de la paroi principale 601 du volet 600 s'étend dans le même plan que la face avant de cet enjoliveur 130.In its standby position, the front face of the main wall 601 of the shutter 600 extends in the same plane as the front face of this trim 130.

En variante, la paroi cylindrique et l'anneau enjoliveur peuvent être formés d'une seule pièce qui constitue alors l'enjoliveur de la prise électrique.Alternatively, the cylindrical wall and the trim ring may be formed in one piece which then constitutes the hubcap of the electrical outlet.

Dans cette position d'attente, le volet 600 obture la majeure partie de la section du puits délimitée par la paroi cylindrique 400 et bloque ainsi l'accès aux éléments de contact électrique logés dans la prise électrique 700.In this waiting position, the shutter 600 closes most of the section of the well defined by the cylindrical wall 400 and thus blocks access to the electrical contact elements housed in the electrical outlet 700.

Le volet 600 comporte en outre des moyens de coulissement 605, 606 dans le puits adaptés à glisser dans des moyens de guidage 415, 416 complémentaires des montants latéraux 410.The flap 600 further comprises sliding means 605, 606 in the well adapted to slide in guide means 415, 416 complementary to the lateral uprights 410.

Les moyens de coulissement 605, 606 du volet 600 comportent deux couples de nervures 605 s'étendant à partir de la face arrière de la paroi principale 601 du volet 600, perpendiculairement à cette face principale 601, et diamétralement opposés.The sliding means 605, 606 of the flap 600 comprise two pairs of ribs 605 extending from the rear face of the main wall 601 of the flap 600, perpendicular to this main face 601, and diametrically opposite.

Ils comportent également deux pattes de coopération 606 diamétralement opposées, formées chacune par les deux encoches à angle droit adaptées au passage des montants latéraux 410.They also comprise two diametrically opposite engagement lugs 606, each formed by the two notches at right angles adapted to the passage of the lateral uprights 410.

Les moyens de guidage 415, 416 de chaque montant latéral 410 comportent deux rainures 415 ménagées en creux dans la face interne 414 du montant latéral 410, dans lesquelles l'un des couples de nervures 605 du volet 600 est adapté à coulisser.The guide means 415, 416 of each lateral upright 410 comprise two grooves 415 hollowed out in the internal face 414 of the lateral upright 410, in which one of the pairs of ribs 605 of the flap 600 is slidably adapted.

Ils comportent également une fente 416 traversant l'épaisseur du montant latéral 410 et débouchant sur son extrémité avant 411, dans laquelle l'une des pattes de coopération 606 du volet 600 est adaptée à coulisser.They also include a slot 416 crossing the thickness of the lateral upright 410 and opening on its front end 411, wherein one of the cooperating lugs 606 of the flap 600 is slidably adapted.

La paroi d'extrémité 415A (figure 1) de chaque rainure 415 des montants latéraux 410 forme une paroi de butée contre laquelle les nervures 605 correspondantes du volet 600 viennent en butée de manière à limiter le déplacement en translation du volet 600 vers l'avant de la prise électrique.The end wall 415A ( figure 1 ) of each groove 415 of the lateral uprights 410 forms an abutment wall against which the corresponding ribs 605 of the flap 600 abut in order to limit the translational movement of the flap 600 towards the front of the electrical outlet.

Le volet 600 coulisse dans le puits conjointement avec un montant central 302 dont l'axe longitudinal est confondu avec l'axe longitudinal X de la paroi cylindrique 400.The shutter 600 slides in the well together with a central upright 302 whose longitudinal axis coincides with the longitudinal axis X of the cylindrical wall 400.

Le montant central 302 est adapté à coulisser axialement dans une rainure 203 entre une position axiale haute correspondant à la position d'attente du volet 600 et une position axiale basse correspondant à la position enfoncée du volet 600.The central upright 302 is adapted to slide axially in a groove 203 between an axial high position corresponding to the waiting position of the shutter 600 and a low axial position corresponding to the depressed position of the shutter 600.

Dans la position axiale haute, le montant central 302 est également adapté à pivoter autour de son axe longitudinal X entre une position angulaire de coulissement dans laquelle il est adapté à coulisser dans la rainure 203 et une position angulaire de verrouillage dans laquelle le coulissement dudit montant central 302 est bloqué de manière à maintenir le volet 600 dans sa position d'attente. Ce pivotement est accompagné d'un mouvement de translation axiale de faible amplitude, comme expliqué ultérieurement.In the high axial position, the central upright 302 is also adapted to pivot about its longitudinal axis X between an angular sliding position in which it is adapted to slide in the groove 203 and an angular locking position in which the sliding of said upright central 302 is blocked so as to maintain the shutter 600 in its waiting position. This pivoting is accompanied by an axial translation movement of low amplitude, as explained later.

Dans sa position axiale basse, le montant central 302 est engagé dans la rainure 203 qui empêche tout pivotement du montant central 302 autour de son axe longitudinal X. Il reste alors dans sa position angulaire de coulissement.In its low axial position, the central upright 302 is engaged in the groove 203 which prevents any pivoting of the central upright 302 about its longitudinal axis X. It then remains in its angular sliding position.

Ce fonctionnement est permis grâce à la structure particulière du montant central 302, qui présente une section au moins partiellement non circulaire.This operation is allowed thanks to the particular structure of the central upright 302, which has an at least partially non-circular section.

Ici le montant central 302 comporte un corps cylindrique 302B muni de deux nervures longitudinales 302A, appelées dans la suite ailettes 302A (figure 1), qui s'étendent de façon diamétralement opposée, en saillie sur ce corps cylindrique 302B.Here the central upright 302 comprises a cylindrical body 302B provided with two longitudinal ribs 302A, called in the following fins 302A ( figure 1 ), which extend diametrically opposite, projecting on the cylindrical body 302B.

Ces ailettes 302A s'étendent sur une portion déterminée du corps cylindrique 302B du montant central 302.These fins 302A extend over a determined portion of the cylindrical body 302B of the central upright 302.

Le montant central 302 coulisse à travers une ouverture centrale 203 de la plaquette 200. La tranche de cette ouverture centrale 203 de la plaquette 200 forme ici la rainure 203 dans laquelle le montant central 302 coulisse.The central upright 302 slides through a central opening 203 of the wafer 200. The wafer of this central opening 203 of the wafer 200 here forms the groove 203 in which the central upright 302 slides.

L'ouverture centrale 203 de la plaquette 200 présente un contour adapté au passage de la portion déterminée du montant central 302 comportant les ailettes 302 lorsque celui-ci se trouve dans sa position angulaire de coulissement, comme représenté sur la figure 8.The central opening 203 of the wafer 200 has a suitable contour at the passage of the determined portion of the central upright 302 having the fins 302 when it is in its angular sliding position, as shown in FIG. figure 8 .

Lorsque le montant central 302 est en position axiale haute et pivote autour de son axe longitudinal, il s'écarte de cette position angulaire de coulissement et les ailettes 302A ne sont plus disposées en face de l'ouverture centrale 203 de la plaquette 200. Elles sont alors adaptées à prendre appui sur une face avant de la plaquette 200 pour bloquer le coulissement du montant central 302 vers l'arrière de la prise électrique 700, comme le montre la figure 4.When the central upright 302 is in the high axial position and pivots about its longitudinal axis, it deviates from this sliding angular position and the fins 302A are no longer disposed opposite the central opening 203 of the wafer 200. are then adapted to bear on a front face of the wafer 200 to block the sliding of the central upright 302 towards the rear of the electrical outlet 700, as shown in FIG. figure 4 .

Le montant central 302 se trouve alors dans sa position angulaire de verrouillage.The central upright 302 is then in its angular locking position.

Il est également prévu des moyens de rappel 301 qui rappellent en permanence le montant central 302 vers sa position axiale haute.It is also provided return means 301 which constantly remind the central upright 302 to its upper axial position.

Ici ces moyens de rappel comportent un ressort de compression 301 logé au moins partiellement à l'intérieur du corps cylindrique creux du montant central 302.Here these return means comprise a compression spring 301 housed at least partially inside the hollow cylindrical body of the central upright 302.

Ce ressort de compression 301 est interposé entre une paroi de la partie arrière 110 du socle 100, par exemple la paroi de fond 111 de cette partie arrière, et une paroi interne du montant central 301.This compression spring 301 is interposed between a wall of the rear portion 110 of the base 100, for example the bottom wall 111 of this rear portion, and an inner wall of the central upright 301.

Lorsque le volet 600 est dans sa position enfoncée à l'arrière du puits de la prise électrique, le montant central 302 est dans sa position axiale basse et est logé en partie dans un logement central 114 adapté de la partie arrière 110 du socle 100.When the flap 600 is in its depressed position at the rear of the well of the electrical outlet, the central upright 302 is in its low axial position and is housed in part in a central recess 114 adapted from the rear portion 110 of the base 100.

Le ressort de compression 301 est alors comprimé à l'intérieur du montant central 302.The compression spring 301 is then compressed inside the central upright 302.

Lorsque la pression de la fiche électrique sur le volet 600 est relâchée, le ressort de compression 301 se détend et repousse le montant central 302 vers l'avant de la prise électrique.When the pressure of the electrical plug on the shutter 600 is released, the compression spring 301 expands and pushes the central post 302 forward of the electrical outlet.

Le montant central 302 coulisse vers l'avant de la prise et repousse le volet 600 vers sa position d'attente.The central upright 302 slides toward the front of the socket and pushes the shutter 600 to its standby position.

Afin de ramener le montant central 302 dans sa position angulaire de verrouillage, la prise électrique selon l'invention comporte en outre des moyens de guidage du montant central 302 de sa position angulaire de coulissement vers sa position angulaire de verrouillage lorsque le montant central 302 coulisse vers l'avant de la prise.In order to return the central upright 302 to its angular locking position, the electrical socket according to the invention further comprises means for guiding the central upright 302 from its angular sliding position towards its locking angular position when the central upright 302 slides. forward of the hold.

Ces moyens de guidage comportent au moins une rampe 528 (figures 3, 5 et 9) prévue sur la face arrière du fond 521 de la cassette 520.These guide means comprise at least one ramp 528 ( figures 3 , 5 and 9 ) provided on the rear face of the bottom 521 of the cassette 520.

Ils comportent de préférence deux rampes diamétralement opposées par rapport au montant central 302, chacune de ces rampes étant adaptée à coopérer avec l'extrémité avant de l'une des ailettes 302A pour faire pivoter le montant central 302 vers sa position angulaire de verrouillage.They preferably comprise two ramps diametrically opposed with respect to the central upright 302, each of these ramps being adapted to cooperate with the front end of one of the fins 302A to pivot the central upright 302 towards its angular locking position.

En pratique, lorsque le montant central 302 coulisse vers l'avant de la prise électrique, l'extrémité avant de chaque ailette 302A arrive en butée sur la rampe 528. L'action de ces ailettes 302A sur la rampe 528 de la cassette 520 ramène le volet dans sa position d'attente.In practice, when the central upright 302 slides towards the front of the electrical outlet, the front end of each fin 302A comes into abutment on the ramp 528. The action of these fins 302A on the ramp 528 of the cassette 520 brings back the shutter in its waiting position.

Dans cette position, l'extrémité arrière de chaque ailette 302A est dégagée de la rainure 203 et le montant 302 peut pivoter.In this position, the rear end of each fin 302A is disengaged from the groove 203 and the post 302 is pivotable.

L'extrémité avant 302A de chaque ailette 302A correspondante glisse alors sur cette rampe. Le montant central 302 pivote en conséquence vers sa position angulaire de verrouillage.The front end 302A of each corresponding fin 302A then slides on this ramp. The central upright 302 pivots accordingly to its locking angular position.

Il est également prévu un obturateur 510 monté sur le montant central 302 à l'extrémité avant 303 de ce montant central 302 (figures 1, 2, 3, 6 et 7).There is also a shutter 510 mounted on the central post 302 at the front end 303 of this central post 302 ( figures 1 , 2 , 3 , 6 and 7 ).

Cet obturateur 510 est disposé à l'arrière du volet 600 et s'étend perpendiculairement à l'axe longitudinal X du montant central 302.This shutter 510 is disposed at the rear of the flap 600 and extends perpendicularly to the longitudinal axis X of the central upright 302.

Il est adapté à pivoter autour de l'axe longitudinal X du montant central 302, entre une position d'obturation des orifices circulaires 604 du volet 600 (figures 2 et 7) dans laquelle il interdit l'accès aux bornes de connexion de phase et de neutre, et une position d'ouverture desdits orifices circulaires 604 dans laquelle il autorise cet accès (figure 6).It is adapted to pivot about the longitudinal axis X of the central upright 302, between a closed position of the circular orifices 604 of the shutter 600 ( figures 2 and 7 ) in which it prohibits access to the phase and neutral connection terminals, and an opening position of said circular orifices 604 in which it authorizes this access ( figure 6 ).

Pour cela, l'obturateur 510 est monté dans un logement 304 du montant central 302 qui sera décrit plus en détail ultérieurement. L'obturateur 510 comporte en outre des moyens d'entraînement 510A adaptés à coopérer avec les broches de la fiche électrique introduites au travers des orifices circulaires 604 du volet 600, pour faire passer l'obturateur 510 de sa position d'obturation à sa position d'ouverture.For this, the shutter 510 is mounted in a housing 304 of the central upright 302 which will be described in more detail later. The shutter 510 further comprises drive means 510A adapted to cooperate with the pins of the electrical plug introduced through the circular orifices 604 of the flap 600, to move the shutter 510 from its closed position to its position opening.

Ces moyens d'entraînement 510A se présentent ici sous la forme de pans inclinés 510A sur lesquels les broches de la fiche électrique insérée dans la prise électrique 700 glissent.These drive means 510A are here in the form of inclined faces 510A on which the pins of the electrical plug inserted in the electrical outlet 700 slide.

Plus précisément, ici l'obturateur 510 est logé dans une cassette 520 montée à l'arrière du volet 600.More precisely, here the shutter 510 is housed in a cassette 520 mounted at the rear of the shutter 600.

Le volet 600, l'obturateur 510, la cassette 520 et le montant central 302 sont ainsi solidaires en translation dans le puits de la prise électrique 700 (figures 2, 3, 6 et 7). La translation du volet 600 vers l'arrière de la prise électrique 700 est d'ailleurs limitée par la butée de la cassette 520 contre la plaquette 200.The flap 600, the shutter 510, the cassette 520 and the central upright 302 are thus integral in translation in the well of the electrical socket 700 ( figures 2, 3 , 6 and 7 ). The translation of the shutter 600 towards the rear of the electrical outlet 700 is also limited by the stop of the cassette 520 against the wafer 200.

La cassette 520 se présente sous la forme d'un parallélépipède fermé en face avant par la paroi principale 601 du volet 600.The cassette 520 is in the form of a parallelepiped closed on the front face by the main wall 601 of the shutter 600.

Cette cassette 520 comporte un fond 521 entouré par une paroi latérale 522 s'élevant perpendiculairement à ce fond 521 (figures 1, 2, 3, 6 et 7).This cassette 520 has a bottom 521 surrounded by a side wall 522 rising perpendicularly to the bottom 521 ( figures 1 , 2 , 3 , 6 and 7 ).

Des dents 525 prévues en saillie de la paroi latérale 522 autorisent le montage par encliquetage du volet 600 sur cette paroi latérale 522 de la cassette.525 teeth provided projecting from the side wall 522 allow snap mounting of the flap 600 on the side wall 522 of the cassette.

L'extrémité avant 303 du montant central 302 traverse un orifice 524 du fond 521 de la cassette 520 (figures 2, 3, 6 et 7).The front end 303 of the central upright 302 passes through an orifice 524 of the bottom 521 of the cassette 520 ( Figures 2, 3 , 6 and 7 ).

Une cloison 524A de la cassette 520 s'élève en bordure de cet orifice 524 pour guider le pivotement de l'obturateur 510 et de l'extrémité du montant 302 (figure 1).A partition 524A of the cassette 520 rises at the edge of this orifice 524 to guide the pivoting of the shutter 510 and the end of the upright 302 ( figure 1 ).

Deux cloisons internes 523 de la cassette 520 forment des cloisons de butée limitant la rotation de l'obturateur 510 (figures 1, 2, 3, 6 et 7).Two internal partitions 523 of the cassette 520 form stop partitions limiting the rotation of the shutter 510 ( figures 1 , 2 , 3 , 6 and 7 ).

Il est prévu par ailleurs des moyens de rappel de l'obturateur 510 vers sa position d'obturation, qui agissent en permanence sur l'obturateur 510.It is further provided means for returning the shutter 510 to its closed position, which act permanently on the shutter 510.

Ces moyens de rappel comportent ici un ressort de compression 530 (figure 1) interposé entre une partie latérale 512 de l'obturateur 510 et la paroi latérale 522 de la cassette 520.These return means here comprise a compression spring 530 ( figure 1 ) interposed between a lateral portion 512 of the shutter 510 and the side wall 522 of the cassette 520.

Une extrémité du ressort de compression 530 est ici logé dans un logement 527 de la cassette 520 délimité par la face interne de la paroi latérale 522 et l'une des cloisons de butée 523. L'autre extrémité du ressort 530 est enfilée sur un pion 512 de l'obturateur 510.One end of the compression spring 530 is here housed in a housing 527 of the cassette 520 delimited by the internal face of the side wall 522 and one of the abutment partitions 523. The other end of the spring 530 is threaded onto a counter 512 of the shutter 510.

Le fond 521 de la cassette 520 comporte en outre des orifices 526 autorisant le passage des broches de la fiche électrique lorsque l'obturateur est dans sa position d'ouverture.The bottom 521 of the cassette 520 further includes orifices 526 allowing the passage of the pins of the electrical plug when the shutter is in its open position.

L'obturateur 510 comporte un barreau central 511 qui est reçu dans le logement 304 prévu à l'extrémité avant 303 du montant central 302 pour son montage sur ce montant central 302.The shutter 510 comprises a central bar 511 which is received in the housing 304 provided at the front end 303 of the central upright 302 for its mounting on the central upright 302.

De manière remarquable, l'obturateur 510 est ici libre de pivoter par rapport au montant central 302 lorsque celui-ci est dans sa position angulaire de coulissement, que le montant central 302 soit par ailleurs dans une position axiale haute ou basse.Remarkably, the shutter 510 is here free to pivot relative to the central upright 302 when it is in its angular sliding position, the central upright 302 is also in a high or low axial position.

En revanche, comme cela sera expliqué plus en détail ci-après, l'obturateur 510 est lié en pivotement au montant central 302 lorsque celui-ci est dans sa position angulaire de verrouillage.However, as will be explained in more detail below, the shutter 510 is pivotally connected to the central upright 302 when it is in its angular locking position.

Ceci est rendu possible par la forme particulière du logement 304 qui reçoit le barreau central 511 de l'obturateur 510. Un jeu est en effet ménagé entre ce barreau central 511 et le bord du logement 304.This is made possible by the particular shape of the housing 304 which receives the central bar 511 of the shutter 510. A clearance is indeed formed between the central bar 511 and the edge of the housing 304.

Plus précisément, le logement 304 se présente sous la forme d'une rainure 304 s'étendant perpendiculairement à l'axe longitudinal du montant central 302 et débouchant à son extrémité avant.More specifically, the housing 304 is in the form of a groove 304 extending perpendicularly to the longitudinal axis of the central upright 302 and opening at its front end.

Cette rainure 304 présente une partie centrale de section inférieure à la section du reste de la rainure 304. En conséquence, cette partie centrale de la rainure 304 encadre étroitement à un jeu près le barreau central 511 de l'obturateur 510 de manière à ce qu'il puisse pivoter autour de l'axe longitudinal du montant central 302.This groove 304 has a central portion of lower section than the rest section of the groove 304. Accordingly, this central portion of the groove 304 closely surrounds a clearance near the central bar 511 of the shutter 510 so that it can pivot about the longitudinal axis of the central upright 302.

Le reste de la rainure 304 s'élargit progressivement de cette partie centrale vers la périphérie du montant central 302, de manière à délimiter un secteur angulaire dans lequel le barreau central 511 de l'obturateur 510 peut pivoter.The remainder of the groove 304 widens progressively from this central portion towards the periphery of the central upright 302, so as to define an angular sector in which the central bar 511 of the shutter 510 can rotate.

La figure 2 montre l'agencement du montant et de l'obturateur 510 lorsque le montant central 302 est dans sa position angulaire de verrouillage.The figure 2 shows the arrangement of the upright and the shutter 510 when the central upright 302 is in its angular locking position.

Le barreau central 511 de l'obturateur est alors en contact avec une partie du bord du logement 304 qui est située du côté vers lequel le barreau central 511 pivote lorsque l'obturateur 510 passe de sa position d'obturation à sa position d'ouverture.The central bar 511 of the shutter is then in contact with a portion of the edge of the housing 304 which is located on the side towards which the central bar 511 pivots when the shutter 510 moves from its closed position to its open position .

Ainsi, lors d'un pivotement dans ce sens, le barreau central 511 de l'obturateur 510 pousse le bord du logement 304 et entraîne le pivotement du montant central 302.Thus, when pivoting in this direction, the central bar 511 of the shutter 510 pushes the edge of the housing 304 and causes pivoting of the central upright 302.

L'obturateur 510 et le barreau central 302 sont alors liés en pivotement.The shutter 510 and the central bar 302 are then pivotally connected.

La forme du logement 304 du montant central 302 est prévue pour que ce pivotement amène le montant central 302 dans sa position angulaire de coulissement, comme le montre la figure 6.The shape of the housing 304 of the central upright 302 is provided for this pivoting brings the central upright 302 in its angular sliding position, as shown in FIG. figure 6 .

Pour cela, l'extrémité avant de chaque ailette 302A du montant central 302 glisse le long de la rampe 528 prévue à l'arrière de la cassette 520. Le mouvement du montant central 302 est donc hélicoïdal (voir figure 3) car la rampe 528 lui impose un léger mouvement de translation vers le bas lorsque l'extrémité avant de chaque ailette 302A glisse le long de la rampe 528.For this, the front end of each fin 302A of the central upright 302 slides along the ramp 528 provided at the rear of the cassette 520. The movement of the central upright 302 is therefore helical (see figure 3 ) because the ramp 528 imposes a slight translational movement downwardly when the front end of each fin 302A slides along the ramp 528.

Dans sa position de verrouillage, le simple pivotement du montant central 302 est donc bloqué dans un sens par la rampe 528 et dans l'autre sens par la butée du bord du logement 304 contre le barreau central 511 de l'obturateur 510, lui-même bloqué par la butée contre l'une des cloisons internes 523 de la cassette 520.In its locking position, the simple pivoting of the central upright 302 is thus blocked in one direction by the ramp 528 and in the other direction by the abutment of the edge of the housing 304 against the central bar 511 of the shutter 510, itself blocked by the stop against one of the internal partitions 523 of the cassette 520.

Dans la position angulaire de coulissement du montant central 302, comme cela est visible sur la figure 6, lorsque l'obturateur est dans sa position d'ouverture, un dégagement est présent entre le barreau central 511 de l'obturateur 510 et le bord du logement 304 du montant central 302. Ce dégagement autorise le pivotement de l'obturateur 510 de sa position d'ouverture vers sa position d'obturation.In the angular position of sliding of the central upright 302, as can be seen on the figure 6 when the shutter is in its open position, a clearance is present between the central bar 511 of the shutter 510 and the edge of the housing 304 of the central upright 302. This clearance allows the pivoting of the shutter 510 of its opening position to its closed position.

En conséquence, si les broches de la fiche électrique ne maintiennent pas l'obturateur 510 dans sa position d'ouverture, celui-ci est rappelé vers sa position d'obturation par le ressort 530. Le barreau central 511 de l'obturateur 510 pivote dans le logement 304 du montant 302.Consequently, if the pins of the electrical plug do not keep the shutter 510 in its open position, it is returned to its shut-off position by the spring 530. The central bar 511 of the shutter 510 rotates in the housing 304 of the amount 302.

Le mouvement de pivotement de l'obturateur 510 n'entraîne alors aucun mouvement du montant central 302.The pivoting movement of the shutter 510 then causes no movement of the central upright 302.

Le montant central 302 ne peut donc empêcher le pivotement de l'obturateur 510.The central amount 302 can not prevent the pivoting of the shutter 510.

Ainsi, en particulier, l'obturateur est libre de revenir à sa position d'obturation, même si le montant central 302 est dans sa position axiale basse dans laquelle il n'est pas libre de pivoter.Thus, in particular, the shutter is free to return to its closed position, even if the central post 302 is in its low axial position in which it is not free to rotate.

La fiche électrique complémentaire comporte avantageusement une face latérale externe de géométrie complémentaire à celle du puits de la prise électrique 700, et son introduction dans le puits est guidée par les fentes 416 des montants latéraux 410.The complementary electrical plug advantageously comprises an external lateral face of geometry complementary to that of the well of the electrical socket 700, and its introduction into the well is guided by the slots 416 of the lateral uprights 410.

En pratique, lorsque le volet 600 est dans sa position d'attente, le montant central 302 est dans sa position axiale haute et dans sa position angulaire de verrouillage et l'obturateur 510 est dans sa position d'obturation.In practice, when the flap 600 is in its standby position, the central upright 302 is in its high axial position and in its locking angular position and the shutter 510 is in its closed position.

L'introduction des broches de la fiche électrique dans les ouvertures circulaires 604 du volet 600 fait pivoter l'obturateur 510 de sa position d'obturation vers sa position d'ouverture par action sur les pans inclinés 510A de cet obturateur 510.The introduction of the pins of the electrical plug into the circular openings 604 of the shutter 600 rotates the shutter 510 from its closed position to its open position by action on the inclined faces 510A of the shutter 510.

Le pivotement de l'obturateur 510 entraîne le pivotement du montant central 302 de sa position angulaire de verrouillage vers sa position angulaire de coulissement.The pivoting of the shutter 510 causes the pivoting of the central upright 302 from its angular locking position to its angular sliding position.

Le volet 600 et le montant central 302 coulissent alors dans le puits sous la pression de la fiche électrique jusqu'à ce que le volet 600 se trouve dans sa position enfoncée. Le montant central 302 se trouve alors dans sa position axiale basse, toujours en position angulaire de coulissement.The shutter 600 and the central upright 302 then slide into the well under the pressure of the electrical plug until the shutter 600 is in its slot. depressed position. The central upright 302 is then in its low axial position, always in angular sliding position.

La fiche électrique est ainsi introduite dans la prise et ses broches sont connectées aux bornes électriques de la prise électrique.The electrical plug is thus inserted into the socket and its pins are connected to the electrical terminals of the electrical socket.

Dans une situation de fonctionnement anormal, si le volet 600 est maintenu dans sa position enfoncée, alors que la fiche électrique est retirée, l'obturateur 510 est alors libre de pivoter autour de l'axe longitudinal du montant central 302.In an abnormal operating situation, if the shutter 600 is held in its depressed position, while the electrical plug is removed, the shutter 510 is then free to rotate about the longitudinal axis of the central post 302.

L'action du ressort 530 sur l'obturateur 510 ramène immédiatement celui-ci vers sa position d'obturation, dès que les broches de la fiche électrique sont extraites des ouvertures circulaires 602 du volet 600.The action of the spring 530 on the shutter 510 immediately brings it back to its closed position, as soon as the pins of the electric plug are extracted from the circular openings 602 of the shutter 600.

L'accès aux bornes de connexion de la prise est ainsi protégée dans cette situation.Access to the connection terminals of the socket is thus protected in this situation.

Si ensuite le volet 600 est libéré, le montant central 302 coulisse vers l'avant sous l'action du ressort de compression 301 décrit précédemment, et ramène le volet 600 dans sa position d'attente.If then the flap 600 is released, the central upright 302 slides forward under the action of the compression spring 301 described above, and returns the flap 600 to its waiting position.

Le montant central 302 glisse alors sur les rampes 528 prévues à l'arrière de la cassette 520 et est ramené dans sa position angulaire de verrouillage.The central upright 302 then slides on the ramps 528 provided at the rear of the cassette 520 and is returned to its angular locking position.

La présente invention n'est nullement limitée aux modes de réalisation décrits et représentés mais l'homme du métier saura y apporter toute variante conforme aux revendications.The present invention is in no way limited to the embodiments described and shown, but the person skilled in the art will be able to make any variant thereof according to the claims.
