Description

La présente invention concerne d'une manière générale les hublots d'éclairage, c'est-à-dire les luminaires qui, communément appelés hublots, sont destinés à être posés en applique sur une quelconque surface de support, tel que mur ou plafond.The present invention relates in general to lighting portholes, that is to say the luminaires which, commonly called portholes, are intended to be installed as a surface-mounted on any support surface, such as wall or ceiling.

Elle vise plus particulièrement, mais non nécessairement exclusivement ceux de ces hublots d'éclairage qui, susceptibles d'être éventuellement soumis à une certaine humidité, comme cela peut être le cas dans les entrées, les escaliers, ou les caves de certains immeubles à usage collectif, doivent par sécurité présenter une certaine étanchéité et répondre à certaines exigences normatives.It targets more particularly, but not necessarily exclusively, those of these lighting portholes which, liable to be possibly subject to a certain humidity, as may be the case in the entrances, stairs, or cellars of certain buildings for use for safety, must for security present a certain tightness and answer certain normative requirements.

Il importe, notamment, que, en l'absence de fil de terre, ils présentent une protection renforcée au niveau des parties sous tension.It is important, in particular, that, in the absence of a ground wire, they have reinforced protection at the level of the live parts.

Les hublots d'éclairage correspondants comportent, globalement, à ce jour, un socle, qui est propre à leur assise sur la surface de support à équiper, et qui comporte en surface un compartiment, dit ici par simple commodité compartiment de raccordement, dans lequel est susceptible de déboucher le câble d'alimentation nécessaire, un support de douille, qui comporte un logement par lequel il est propre à recevoir une douille, et qui, formant une pièce distincte du socle, est adapté à être rapporté de manière amovible sur celui-ci, en fermant alors son compartiment de raccordement, et un diffuseur, qui, lui aussi, est adapté à être rapporté sur le socle, autour du compartiment de raccordement, en délimitant avec le socle le volume nécessaire au logement d'une ampoule.The corresponding lighting portholes generally comprise, to date, a base, which is specific to their seating on the support surface to be fitted, and which comprises on the surface a compartment, said here for simple convenience, connection compartment, in which is capable of unblocking the necessary power cable, a socket support, which comprises a housing by which it is suitable for receiving a socket, and which, forming a separate part of the base, is adapted to be removably attached to that -this, by then closing its connection compartment, and a diffuser, which, too, is adapted to be attached to the base, around the connection compartment, by delimiting with the base the volume necessary for housing a bulb.

Pour satisfaire à la norme à respecter, tout accès au compartiment de raccordement doit être interdit en maniement normal sans l'aide d'un outil.In order to comply with the standard to be observed, access to the connection compartment must be prohibited in normal handling without the aid of a tool.

A ce jour, le support de douille est rapporté pour ce faire par vissage sur le socle, et, en pratique, plusieurs vis, au nombre par exemple de trois, sont nécessaires à cet effet.To date, the socket support is reported to do this by screwing on the base, and, in practice, several screws, for example three in number, are necessary for this purpose.

Une telle fixation par vis est décrite par exemple dans le document GB-A-735 589, dans lequel, par ailleurs, le compartiment de raccordement n'est que partiellement fermé par le support de douille, et dans lequel, corollairement, il n'y a pas de diffuseur.Such screw fixing is described for example in document GB-A-735 589, in which, moreover, the connection compartment is only partially closed by the socket support, and in which, as a corollary, there is no diffuser.

Il s'avère fréquemment que, à terme, et par suite par exemple d'un oubli, une ou plusieurs des vis viennent à être manquantes, au détriment de la sécurité.It frequently turns out that, in the long term, and as a result for example of an oversight, one or more of the screws may be missing, to the detriment of safety.

Dans les documents EP-A-0 022 963 ou EP-A-0 354 264, qui ne concernent cependant pas spécifiquement les hublots d'éclairage, il est décrit la mise en oeuvre d'un montage à coulissement et de moyens de verrouillage par encliquetage entre un support de douille et un socle.In the documents EP-A-0 022 963 or EP-A-0 354 264, which however do not specifically relate to the lighting portholes, the implementation of a sliding assembly and locking means is described. latching between a socket holder and a base.

La présente invention a pour objet un hublot d'éclairage du genre concerné caractérisé en ce que, des moyens de montage à coulissement, d'une part, et des moyens de verrouillage par encliquetage, d'autre part, intervenant entre le support de douille et le socle, avec, pour les moyens de montage à coulissement, deux glissières, qui sont prévues sur le socle, de part et d'autre du compartiment de raccordement, et avec lesquelles le support de douille est adapté à venir en prise à coulissement, le support de douille comporte une semelle, par les tranches latérales de laquelle il est adapté à venir en prise avec les glissières du socle, et qui, lorsqu'il est en place, couvre le compartiment de raccordement.The subject of the present invention is a lighting porthole of the type concerned, characterized in that, sliding mounting means, on the one hand, and snap-lock means, on the other hand, intervening between the socket support and the base, with, for the sliding mounting means, two slides, which are provided on the base, on either side of the connection compartment, and with which the socket support is adapted to come into sliding engagement , the socket support comprises a sole, by the lateral edges of which it is adapted to engage with the rails of the base, and which, when in place, covers the connection compartment.

Ainsi, lors de la mise en place du support de douille, il suffit de le poser sur le socle au droit des moyens de montage à coulissement prévus pour lui sur celui-ci et de le pousser.Thus, during the installation of the socket support, it suffices to place it on the base in line with the sliding mounting means provided for it thereon and to push it.

En effet, au terme de son engagement dans ces moyens de montage à coulissement, les moyens de verrouillage par encliquetage prévus par ailleurs interviennent d'eux-mêmes systématiquement, en s'opposant dès lors à tout retrait sans outil.Indeed, at the end of its engagement in these sliding mounting means, the latching locking means provided elsewhere intervene systematically by themselves, therefore opposing any removal without tools.

La sécurité recherchée est ainsi effectivement garantie, de manière très simple et en toute certitude, sans qu'il y ait nécessairement lieu pour ce faire de mettre en oeuvre une quelconque vis.The desired security is thus effectively guaranteed, in a very simple manner and with complete certainty, without it necessarily being necessary to do this by using any screw.

La mise en place du support de douille se trouve de surcroit simplifiée, et facilitée.The installation of the socket support is further simplified and facilitated.

Mais il va de soi que, si désiré, et cela est prévu suivant un premier développement de l'invention, une vis au moins peut éventuellement être mise en oeuvre en sus, pour bloquer de manière positive les moyens de verrouillage par encliquetage mis en oeuvre, et ainsi apporter une garantie supplémentaire.But it goes without saying that, if desired, and this is provided according to a first development of the invention, at least one screw can possibly be used in addition, to positively block the latching locking means used , and thus provide an additional guarantee.

En outre, lorsqu'un réflecteur est prévu, ce réflecteur, suivant un deuxième développement de l'invention, recouvre au moins pour partie le support de douille lorsque celui-ci est en place sur le socle, et sa fixation sur ce socle se fait par au moins une vis.In addition, when a reflector is provided, this reflector, according to a second development of the invention, covers at least partially the socket support when the latter is in place on the base, and its attachment to this base is made by at least one screw.

Ainsi, en maniement normal, la nécessité qu'il y a de disposer d'un outil pour accéder au compartiment de raccordement se trouve renforcée, puisqu'il faut au préalable procéder à la dépose du réflecteur, et, donc, au dévissage de la vis assurant la fixation de celui-ci.Thus, in normal handling, the need to have a tool to access the connection compartment is reinforced, since it is first necessary to remove the reflector, and therefore unscrew the the screw securing it.

De ce point de vue, le hublot d'éclairage suivant l'invention apporte avantageusement une double isolation pour les parties sous tension.From this point of view, the lighting porthole according to the invention advantageously provides double insulation for the live parts.

Les caractéristiques et avantages de l'invention ressortiront d'ailleurs de la description qui va suivre, à titre d'exemple, en référence aux dessins schématiques annexés sur lesquels :

De manière également connue en soi, le hublot d'éclairage suivant l'invention comporte, en sus, dans la forme de réalisation représentée, un réflecteur 18, destiné à être superposé au fond 20 du socle 10, sur une partie au moins de la surface de ce fond 20, sous l'ampoule mise en oeuvre.In a manner also known per se, the lighting porthole according to the invention comprises, in addition, in the embodiment shown, a reflector 18, intended to be superimposed on the bottom 20 of the base 10, on at least part of the surface of this bottom 20, under the bulb used.

Il s'agit, par exemple, d'un simple flan métallique, de faible épaisseur, convenablement découpé et conformé.It is, for example, a simple metal blank, of small thickness, suitably cut and shaped.

Dans la forme de réalisation représentée, le socle 10 comporte une paroi latérale externe 21, qui est globalement tronconique, en allant en s'évasant vers l'arrière, et une paroi latérale interne 22, qui est également globalement tronconique, en allant en s'évasant vers l'avant.In the embodiment shown, the base 10 has an external side wall 21, which is generally frustoconical, flaring backwards, and an internal side wall 22, which is also generally tapered, flaring forward.

Ces deux parois latérales externe et interne 21, 22 se rejoignent vers l'avant, en formant conjointement une rainure 23 circulaire propre à la réception du diffuseur 16.These two external and internal lateral walls 21, 22 meet towards the front, jointly forming a circular groove 23 suitable for receiving the diffuser 16.

Le compartiment de raccordement 11 est adjacent à la paroi latérale interne 22.The connection compartment 11 is adjacent to the internal side wall 22.

Il s'étend entre deux bossages 24 qui, eux aussi adjacents à cette paroi latérale interne 22, font saillie sur le fond 20, en s'étendant globalement suivant une même corde de celui-ci.It extends between two bosses 24 which, also adjacent to this internal lateral wall 22, protrude from the bottom 20, extending generally along the same cord thereof.

Le compartiment de raccordement 11 débouche ainsi vers l'extérieur tant en façade, perpendiculairement au fond 20, que latéralement, parallèlement à ce fond 20.The connection compartment 11 thus opens outwards both on the front, perpendicular to the bottom 20 and laterally, parallel to this bottom 20.

Autrement dit, le compartiment de raccordement 11 comporte un débouché supérieur 25, à niveau avec la surface supérieure des bossages 24 qui le délimitent, et un débouché latéral 26, formé par l'espace libre entre ces bossages 24.In other words, the connection compartment 11 has an upper outlet 25, level with the upper surface of the bosses 24 which delimit it, and a lateral outlet 26, formed by the free space between these bosses 24.

Suivant l'invention, entre le support de douille 13 et le socle 10 interviennent, d'une part, des moyens de montage à coulissement, et, d'autre part, des moyens de verrouillage par encliquetage.According to the invention, between the socket support 13 and the base 10 intervene, on the one hand, sliding mounting means, and, on the other hand, latching locking means.

Dans la forme de réalisation représentée, les moyens de montage à coulissement comportent deux glissières 28, qui, parallèles l'une à l'autre, sont prévues sur le socle 10, de part et d'autre du compartiment de raccordement 11, et avec lesquelles le support de douille 13 est adapté à venir en prise à coulissement.In the embodiment shown, the sliding mounting means comprise two slides 28, which, parallel to each other, are provided on the base 10, on either side of the connection compartment 11, and with which the socket support 13 is adapted to come into sliding engagement.

En pratique, les glissières 28 font saillie sur la surface supérieure des bossages 24 du socle 10, avec des retours en équerre 29 dirigés l'un vers l'autre, parallèlement à cette surface supérieure, à distance de celle-ci, et elles sont chacune respectivement précédées de parois obliques d'engagement 30, qui, dirigées vers leur fond 31, en formant ainsi conjointement une goulotte tronconique, sont adaptées à y faciliter l'engagement du support de douille 13.In practice, the slides 28 protrude from the upper surface of the bosses 24 of the base 10, with angled returns 29 directed towards one another, parallel to this upper surface, at a distance therefrom, and they are each respectively preceded by oblique engagement walls 30, which, directed towards their bottom 31, thus jointly forming a frustoconical trough, are adapted to facilitate engagement of the socket support 13 therein.

Le support de douille 13 comporte, en dièdre, d'une part, une semelle 32, par laquelle il est adapté à occulter le débouché supérieur 25 du compartiment de raccordement 11, et, d'autre part, un bord tombé 34, par lequel il est adapté à occulter le débouché latéral 26 de celui-ci.The socket support 13 comprises, in a dihedral, on the one hand, a sole 32, by which it is adapted to conceal the upper outlet 25 of the connection compartment 11, and, on the other hand, a fallen edge 34, by which it is adapted to conceal the lateral outlet 26 thereof.

Les tranches latérales 35 de la semelle 32 sont droites et parallèles l'une à l'autre, et, par ces tranches latérales 35, le support de douille 13 est directement adapté à venir en prise avec les glissières 28 du socle 10.The lateral edges 35 of the sole 32 are straight and parallel to each other, and, by these lateral edges 35, the socket support 13 is directly adapted to engage with the slides 28 of the base 10.

Si désiré, la semelle 32 peut être cambrée, au moins au niveau de ses tranches latérales 35, pour permettre de rattraper un éventuel jeu de montage entre ces tranches latérales 35 et les glissières 28.If desired, the sole 32 can be arched, at least at the level of its lateral edges 35, in order to make up for any mounting clearance between these lateral edges 35 and the slides 28.

Par exemple, son cambrage peut l'affecter dans sa totalité, en se développant suivant un axe parallèle aux glissières 28, sa partie médiane étant alors plus proche du fond 20 du socle 10 que ses tranches latérales 35.For example, its camber can affect it in its entirety, developing along an axis parallel to the slides 28, its middle part then being closer to the bottom 20 of the base 10 than its lateral edges 35.

De préférence, dans ce cas, et tel que schématisé en traits interrompus sur les figures 4 et 5, le socle 10 présente, en saillie sur sa paroi latérale interne 22, dans le compartiment de raccordement 11, globalement à mi-distance des glissières 28, au moins une nervure 17, dont la tranche supérieure 27, chanfreinée à cet effet, forme une rampe de positionnement avec laquelle coopère en appui, en fin de course, le bord de la semelle 32 du support de douille 13 pour atteindre le bord supérieur de cette paroi latérale interne 22.Preferably, in this case, and as shown diagrammatically in broken lines in FIGS. 4 and 5, the base 10 has, projecting from its internal side wall 22, in the connection compartment 11, generally halfway between the slides 28 , at least one rib 17, the upper edge 27 of which is chamfered for this purpose, forms a positioning ramp with which cooperates in support, at the end of the stroke, the edge of the sole 32 of the socket support 13 to reach the upper edge of this internal side wall 22.

Dans la forme de réalisation représentée, deux nervures 17 sont ainsi prévues, parallèlement l'une à l'autre, à distance l'une de l'autre, à compter du fond 20 du socle 10, dans le compartiment de raccordement 11.In the embodiment shown, two ribs 17 are thus provided, parallel to one another, at a distance from each other, from the bottom 20 of the base 10, in the connection compartment 11.

Le logement 14 que présente le support de douille 13 pour recevoir une douille 15 forme une saillie sur sa semelle 32, et le débouché 36 de ce logement 14 mord pour partie sur son bord tombé 34.The housing 14 presented by the socket support 13 for receiving a socket 15 forms a projection on its sole 32, and the outlet 36 of this housing 14 partly bites on its fallen edge 34.

Intérieurement, ce logement 14 présente au moins une patte élastiquement déformable propre à l'encliquetage de la douille 15.Internally, this housing 14 has at least one elastically deformable tab suitable for the snap-fastening of the socket 15.

Les dispositions correspondantes ne relevant pas de la présente invention, elles ne seront pas décrites ici.The corresponding provisions not pertaining to the present invention, they will not be described here.

Entre le support de douille 13 et le socle 10 interviennent des moyens d'appui et de guidage, qui, lors de la mise en place du support de douille 13, et tel qu'explicité ultérieurement, permettent à ce support de douille 13 de trouver un appui sur le socle 10 en amont des moyens de montage à coulissement prévus pour sa mise en place.Between the socket support 13 and the base 10 intervene support and guide means, which, during the installation of the socket support 13, and as explained later, allow this socket support 13 to find pressing on the base 10 upstream of the sliding mounting means provided for its installation.

Dans la forme de réalisation représentée, ces moyens d'appui et de guidage comportent, sur le socle 10, un bossage 38, qui, intermédiaire entre les bossages 24, fait saillie sur le fond 20, dans le compartiment de raccordement 11, et, sur le support de douille 13, une cloison 39, par laquelle celui-ci est apte à porter sur ce bossage 38, et, plus précisément, sur la surface supérieure 40, parallèle au fond 20, de celui-ci.In the embodiment shown, these support and guide means comprise, on the base 10, a boss 38, which, intermediate between the bosses 24, protrudes from the bottom 20, in the connection compartment 11, and, on the socket support 13, a partition 39, by which the latter is capable of bearing on this boss 38, and, more precisely, on the upper surface 40, parallel to the bottom 20, of the latter.

Cette cloison 39 du support de douille 13 s'étend en saillie sur sa surface inférieure, parallèlement aux tranches latérales 35 de sa semelle 32.This partition 39 of the socket support 13 extends projecting on its lower surface, parallel to the lateral edges 35 of its sole 32.

En pratique, elle s'étend à compter de la paroi latérale du logement 14 qu'il comporte pour la douille 15.In practice, it extends from the side wall of the housing 14 which it comprises for the socket 15.

Quant au bossage 38 du socle 10, il est à niveau avec le débouché latéral 26 du compartiment de raccordement 11.As for the boss 38 of the base 10, it is level with the lateral outlet 26 of the connection compartment 11.

Autrement dit, sa surface supérieure 40 est à niveau avec le fond 41 de ce débouché latéral 26.In other words, its upper surface 40 is level with the bottom 41 of this lateral outlet 26.

Préférentiellement, et tel que représenté, le débouché latéral 26 du compartiment de raccordement 11 est précédé d'une paroi oblique d'engagement 42 qui rejoint son niveau, et, plus précisément, celui de son fond 41, en continuité avec la surface supérieure 40 du bossage 38.Preferably, and as shown, the lateral outlet 26 of the connection compartment 11 is preceded by an oblique engagement wall 42 which joins its level, and, more precisely, that of its bottom 41, in continuity with the upper surface 40 of boss 38.

En pratique, cette paroi oblique d'engagement 42 s'étend suivant une corde du fond 20, sur toute la longueur de cette corde, en reliant l'un à l'autre les deux bossages 24, et, le long de son bord opposé à ces bossages 24, elle est reliée au fond 20 par une paroi droite 43 perpendiculaire à celui-ci.In practice, this oblique engagement wall 42 extends along a bottom rope 20, over the entire length of this rope, connecting the two bosses 24 to each other, and, along its opposite edge. to these bosses 24, it is connected to the bottom 20 by a straight wall 43 perpendicular thereto.

Les moyens de verrouillage par encliquetage intervenant entre le support de douille 13 et le socle 10 comportent, d'une manière générale, sur l'un quelconque des éléments que constituent ce support de douille 13 et ce socle 10, au moins une languette élastiquement déformable 45 et, sur l'autre de ces éléments, un cran de retenue 46 avec lequel cette languette élastiquement déformable 45 est destinée à coopérer en butée.The latching locking means intervening between the socket support 13 and the base 10 generally comprise, on any one of the elements that constitute this socket support 13 and this base 10, at least an elastically deformable tongue 45 and, on the other of these elements, a retaining notch 46 with which this elastically deformable tongue 45 is intended to cooperate in abutment.

Dans la forme de réalisation représentée sur les figures 1 à 9, une seule languette élastiquement déformable 45 est prévue, et elle équipe le support de douille 13.In the embodiment shown in FIGS. 1 to 9, a single elastically deformable tongue 45 is provided, and it equips the socket support 13.

En pratique, la languette élastiquement déformable 45 s'étend en porte-à-faux à partir du bord libre du bord tombé 34 du support de douille 13, en formant avec ce bord tombé 34 un dièdre d'orientation inverse de celle qu'il forme avec la semelle 32.In practice, the elastically deformable tongue 45 extends in overhang from the free edge of the fallen edge 34 of the socket support 13, forming with this dropped edge 34 a dihedral of opposite orientation to that which it shape with sole 32.

Sa pente est sensiblement égale à celle de la paroi oblique d'engagement 42 du socle 10.Its slope is substantially equal to that of the oblique engagement wall 42 of the base 10.

La languette élastiquement déformable 45 est ainsi apte à se superposer à cette paroi oblique d'engagement 42, sur une portion de celle-ci.The elastically deformable tongue 45 is thus able to be superimposed on this oblique engagement wall 42, on a portion of the latter.

Son bord libre est droit.Its free edge is straight.

Dans la forme de réalisation représentée, la languette élastiquement déformable 45 unique ainsi mise en oeuvre est excentrée par rapport à la zone médiane du support de douille 13 intermédiaire entre les glissières 28, en étant déportée vers l'une de celles-ci.In the embodiment shown, the single elastically deformable tongue 45 thus implemented is eccentric with respect to the central region of the socket support 13 intermediate between the slides 28, being offset towards one of these.

Elle s'étend ainsi à proximité de l'extrémité latérale correspondante du bord tombé 34.It thus extends near the corresponding lateral end of the fallen edge 34.

Conjointement, le cran de retenue 46 est formé par une nervure qui, en saillie sur la paroi oblique d'engagement 42 du socle 10, borde, localement, le bord de celle-ci opposé au compartiment de raccordement 11, en continuité avec la paroi droite 43.Jointly, the retaining catch 46 is formed by a rib which, projecting from the oblique engagement wall 42 of the base 10, borders locally the edge thereof opposite the connection compartment 11, in continuity with the wall right 43.

A l'image du bord libre de la languette élastiquement déformable 45, ce cran de retenue 46 est droit.Like the free edge of the elastically deformable tongue 45, this retaining notch 46 is straight.

Préférentiellement, et tel que représenté, il présente, cependant, dans sa zone médiane, une échancrure 48, qui, propre à l'insertion d'un quelconque outil, par exemple la lame d'un tournevis, permet d'agir sur la languette élastiquement déformable 45, sur la surface inférieure de celle-ci, lorsque cette languette élastiquement déformable 45 est en prise avec lui.Preferably, and as shown, it has, however, in its central zone, a notch 48, which, suitable for the insertion of any tool, for example the blade of a screwdriver, makes it possible to act on the tongue elastically deformable 45, on the lower surface thereof, when this elastically deformable tongue 45 is engaged with it.

Dans la forme de réalisation représentée, à l'extrémité du cran de retenue 46 située du côté de celui-ci le plus éloigné du rayon du socle 10 suivant lequel s'étend globalement le support de douille 13, une nervure 47 s'étend en équerre par rapport à ce cran de retenue, en reliant celui-ci à la paroi oblique d'engagement 42, pour former une butée latérale pour la languette élastiquement déformable 45 et ainsi s'opposer à tout gauchissement éventuel du support de douille 13, c'est-à-dire à toute rotation sur lui-même de ce support de douille 13 autour d'un axe perpendiculaire à sa semelle 32 dans les limites de l'éventuel jeu de montage autorisé dans un tel sens par les glissières 28.In the embodiment shown, at the end of the retaining notch 46 located on the side thereof the furthest from the radius of the base 10 along which the socket support 13 generally extends, a rib 47 extends in square with respect to this retaining notch, by connecting it to the oblique engagement wall 42, to form a lateral stop for the elastically deformable tongue 45 and thus oppose any possible warping of the socket support 13, c 'that is to say, any rotation on itself of this socket support 13 about an axis perpendicular to its sole 32 within the limits of the possible mounting clearance authorized in such a direction by the slides 28.

Si désiré, et tel que représenté, la languette élastiquement déformable 45 présente, dans sa zone médiane, un perçage 50, pour la mise en oeuvre d'une vis 51 destinée à coopérer en vissage avec un alésage 52, qui, prévu en correspondance à cet effet sur la paroi oblique d'engagement 42 du socle 10, s'étend à la faveur d'un puits 53 présent en saillie sur la surface inférieure de celle-ci.If desired, and as shown, the elastically deformable tongue 45 has, in its central zone, a bore 50, for the implementation of a screw 51 intended to cooperate in screwing with a bore 52, which, provided in correspondence with this effect on the oblique engagement wall 42 of the base 10, extends through a well 53 projecting from the lower surface thereof.

De forme générale en cuvette, le réflecteur 18 présente un bord circulaire 55, au contour de la paroi latérale interne 22 du socle 10, et un bord droit 56, qui, à l'image de la paroi oblique d'engagement 42 de celui-ci, s'étend globalement suivant une corde.Generally in a bowl, the reflector 18 has a circular edge 55, at the contour of the internal side wall 22 of the base 10, and a straight edge 56, which, like the oblique engagement wall 42 of the latter ci, generally extends along a cord.

Ce bord droit 56 présente une échancrure 57 dans sa zone médiane, pour son engagement sous la douille 15.This straight edge 56 has a notch 57 in its central region, for its engagement under the sleeve 15.

Il présente en outre, disposés chacun respectivement de part et d'autre de cette échancrure 57, des retours 58 par lesquels il est apte à recouvrir au moins pour partie le support de douille 13 lorsque celui-ci est en place sur le socle 10, au droit des glissières 28, en s'opposant ainsi au retrait de ce support de douille 13 sans qu'il soit procédé à sa propre dépose.It also has, each arranged respectively on either side of this notch 57, returns 58 by which it is able to cover at least partially the socket support 13 when the latter is in place on the base 10, in line with the slides 28, thus opposing the withdrawal of this socket support 13 without its own removal.

La fixation du réflecteur 18 au socle 10 se fait par au moins une vis 60.The reflector 18 is fixed to the base 10 by at least one screw 60.

Dans les formes de réalisation représentées, seule une telle vis 60 est prévue, et, préférentiellement, il est fait en sorte qu'elle puisse rester à demeure sur le socle 10.In the embodiments shown, only such a screw 60 is provided, and, preferably, it is made so that it can remain permanently on the base 10.

Dans la forme de réalisation plus particulièrement représentée sur les figures 1 à 11, le perçage 61 correspondant du réflecteur 18 est à cet effet en forme de trou de serrure.In the embodiment more particularly shown in Figures 1 to 11, the corresponding hole 61 of the reflector 18 is for this purpose in the form of a keyhole.

En variante, figures 12, 13, ce perçage 61 peut si désiré se présenter sous la forme d'une fente radiale, et, à son extrémité la plus proche du centre du fond 20 du socle 10, il est alors en continuité avec un évidement, qui permet l'engagement de l'ensemble sur la tête de la vis 60, et à la faveur duquel est formé en saillie, par embouti, un bossage 67.As a variant, in FIGS. 12, 13, this bore 61 can if desired be in the form of a radial slot, and, at its end closest to the center of the bottom 20 of the base 10, it is then continuous with a recess , which allows the engagement of the assembly on the head of the screw 60, and by virtue of which a projection 67 is formed by projection, by stamping.

Formant écran entre la tête de la vis 60 et l'ampoule mise en oeuvre, ce bossage 67 est de nature à réduire l'éventuel échauffement de celle-ci.Forming a screen between the head of the screw 60 and the bulb used, this boss 67 is capable of reducing the possible heating thereof.

Pour l'entrée du câble 12 dans le compartiment de raccordement 11, il est prévu, sur le socle 10, d'une part, une arrivée filetée 62, qui, de sa paroi latérale externe 21 à sa paroi latérale interne 22, conduit directement à ce compartiment de raccordement 11, tout en étant préférentiellement occultée par un opercule défonçable 63 à son débouché dans celui-ci, et, d'autre part, en conjonction avec des opercules défonçables 64 également présents dans ce compartiment de raccordement 11, des opercules défonçables 65 prévus de place en place dans la paroi latérale externe 21, à la surface intérieure de celle-ci.For the entry of the cable 12 into the connection compartment 11, there is provided, on the base 10, on the one hand, a threaded inlet 62, which, from its external side wall 21 to its internal side wall 22, leads directly to this connection compartment 11, while preferably being concealed by a knockout cover 63 at its outlet therein, and, on the other hand, in conjunction with knockouts 64 also present in this connection compartment 11, covers knockouts 65 provided from place to place in the outer side wall 21, on the inner surface thereof.

Dans la forme de réalisation représentée, trois opercules défonçables 64 sont prévus dans le compartiment de raccordement 11, à raison d'un par bossage 24, 38.In the embodiment shown, three knock-out covers 64 are provided in the connection compartment 11, at the rate of one per boss 24, 38.

Pour le cas où le hublot d'éclairage suivant l'invention serait disposé verticalement sur un mur, il est également prévu, sur le fond de la rainure 23 du socle 10, en positions diamétralement opposées l'un à l'autre, l'un du côté de l'arrivée filetée 62, l'autre du côté opposé à celle-ci, deux opercules défonçables 66, pour assurer une évacuation d'eau.In the case where the lighting porthole according to the invention is arranged vertically on a wall, provision is also made, on the bottom of the groove 23 of the base 10, in positions diametrically opposite one another, the one on the side of the threaded inlet 62, the other on the side opposite the latter, two knock-out lids 66, to ensure drainage of water.

Seul est en pratique éliminé en service l'opercule défonçable 66 situé le plus bas.In practice, only the lowest knockout 66 is eliminated in service.

Dans la forme de réalisation représentée, le support de douille 13 présente, en saillie parallèlement l'une à l'autre sur la surface inférieure de sa semelle 32, de part et d'autre du logement 14 prévu pour la douille 15, deux cloisons 68, qui, à proximité du bord tombé 34, présentent chacune une encoche 69.In the embodiment shown, the socket support 13 has, projecting parallel to one another on the lower surface of its sole 32, on either side of the housing 14 provided for the socket 15, two partitions 68, which, near the fallen edge 34, each have a notch 69.

Pour la mise en oeuvre du hublot d'éclairage suivant l'invention, il peut être procédé comme suit.For the implementation of the lighting porthole according to the invention, it can be proceeded as follows.

Le support de douille 13 étant dégagé du socle 10, supposé lui en place, avec un câble 12 débouchant dans son compartiment de raccordement 11, il est procédé au raccordement de chacun des conducteurs 70 de ce câble 12 avec les bornes de connexion correspondantes de la douille 15, figure 9.The socket support 13 being disengaged from the base 10, assumed to be in place, with a cable 12 opening into its connection compartment 11, each of the conductors 70 of this cable 12 is connected with the corresponding connection terminals of the socket 15, figure 9.

Préférentiellement, et tel que représenté sur la figure 9, les conducteurs 70 sont passés à l'extérieur de l'espace délimité par les cloisons 68 que présente le support de douille 13, en étant chacun individuellement engagés dans les encoches 69 de celles-ci, ce qui, au-delà du guidage, assure avantageusement leur retenue mécanique par rapport à la douille 15.Preferably, and as shown in FIG. 9, the conductors 70 are passed outside the space delimited by the partitions 68 presented by the socket support 13, each being individually engaged in the notches 69 thereof. , which, beyond the guide, advantageously ensures their mechanical retention relative to the sleeve 15.

Tel que schématisé en traits interrompus sur la figure 5, le support de douille 13 ainsi raccordé au câble 12 est alors posé sur le socle 10, perpendiculairement au fond 20 de celui-ci, suivant la flèche F1 de cette figure 5, sensiblement au droit du compartiment de raccordement 11.As shown diagrammatically in broken lines in FIG. 5, the socket support 13 thus connected to the cable 12 is then placed on the base 10, perpendicular to the bottom 20 thereof, according to the arrow F1 in this FIG. 5, substantially at right of the connection compartment 11.

Il suffit ensuite de le pousser en direction de ce compartiment de raccordement 11, suivant la flèche F2 de la figure 5.It then suffices to push it in the direction of this connection compartment 11, according to the arrow F2 in FIG. 5.

En effet, guidé, d'abord par la paroi oblique d'engagement 42, sur laquelle vient porter sa cloison 39, puis par la surface supérieure 40 du bossage 38 qui est en continuité avec cette paroi oblique d'engagement 42, il vient alors s'engager de lui-même dans les glissières 28, du fait des parois obliques d'engagement 30 précédant celles-ci.Indeed, guided, first by the oblique engagement wall 42, on which comes its partition 39, then by the upper surface 40 of the boss 38 which is in continuity with this oblique engagement wall 42, it then comes engage itself in the slides 28, due to the oblique engagement walls 30 preceding them.

Au terme de cet engagement, la languette élastiquement déformable 45 du support de douille 13 vient se prendre derrière le cran de retenue 46 du socle 10, après avoir franchi élastiquement celui-ci, figure 6.At the end of this engagement, the elastically deformable tongue 45 of the socket support 13 is caught behind the retaining notch 46 of the base 10, after having elastically crossed the latter, FIG. 6.

Le montage du support de douille 13 sur le socle 10 est dès lors assuré.The mounting of the socket support 13 on the base 10 is therefore ensured.

Ainsi qu'on le notera, lorsque le support de douille 13 est ainsi en place, sa semelle 32 couvre le compartiment de raccordement 11.As will be noted, when the socket support 13 is thus in place, its sole 32 covers the connection compartment 11.

Dans la forme de réalisation représentée, il se trouve parachevé par la vis 51, celle-ci venant bloquer de manière positive ce support de douille 13 sur le socle 10.In the embodiment shown, it is completed by the screw 51, the latter coming to positively block this socket support 13 on the base 10.

Une fois lui-même mis en place, et fixé par la vis 60, le réflecteur 18 vient recouvrir le fond 20 du socle 10, le débouché de ses glissières 28, et la partie correspondante de la semelle 32 du support de douille 13 aussi bien que la languette élastiquement déformable 45 de celui-ci et la vis 51 assurant sa fixation.Once itself set up, and fixed by the screw 60, the reflector 18 covers the bottom 20 of the base 10, the outlet of its slides 28, and the corresponding part of the sole 32 of the socket support 13 as well that the elastically deformable tongue 45 of the latter and the screw 51 ensuring its fixing.

Dans la variante de réalisation représentée sur les figures 10 et 11, deux languettes élastiquement déformables 45' sont prévues, et elles équipent le socle 10, en s'étendant chacune respectivement de part et d'autre du compartiment de raccordement 11, en saillie sur la paroi oblique d'engagement 42.In the alternative embodiment shown in FIGS. 10 and 11, two elastically deformable tongues 45 ′ are provided, and they equip the base 10, each extending respectively on either side of the connection compartment 11, projecting from the oblique engagement wall 42.

Le cran de retenue 46' correspondant est alors prévu sur le support de douille 13.The corresponding retaining notch 46 ′ is then provided on the socket support 13.

Préférentiellement, dans ce cas, les languettes élastiquement déformables 45' sont légèrement obliques par rapport aux glissières 28.Preferably, in this case, the elastically deformable tongues 45 ′ are slightly oblique with respect to the slides 28.

Elles forment donc conjointement un cône de nature à faciliter l'engagement du support de douille 13 dans les glissières 28, en complément des parois obliques d'engagement 30 associées à celles-ci ou en substitution à ces parois obliques d'engagement 30.They therefore jointly form a cone capable of facilitating the engagement of the socket support 13 in the slides 28, in addition to the oblique engagement walls 30 associated with them or in substitution for these oblique engagement walls 30.

La présente invention ne se limite d'ailleurs pas aux formes de réalisation décrites et représentées, mais englobe toute variante d'exécution et/ou de combinaison de leurs divers éléments.The present invention is moreover not limited to the embodiments described and shown, but encompasses any variant embodiment and / or combination of their various elements.

En particulier, le contour du socle mis en oeuvre n'est pas nécessairement circulaire.In particular, the contour of the base used is not necessarily circular.

Au contraire, il pourrait par exemple être tout aussi bien ovale.On the contrary, it could for example be just as well oval.
