Description

L'invention se rapporte à un hublot étanche pour lampe d'éclairage comprenant une embase à fixer sur une paroi et un diffuseur translucide convexe avec une tranche dressée, tenu par un rebord périphérique dans une bride en couronne apte à appliquer, suivant un plan de joint la tranche dressée du diffuseur sur une portée annulaire de l'embase, une pluralité de vis traversant des passages dans la bride pour s'engager dans des taraudages de l'embase et ainsi serrer la tranche du diffuseur sur la portée annulaire de l'embase.The invention relates to a watertight porthole for a lighting lamp comprising a base to be fixed to a wall and a convex translucent diffuser with an upright edge, held by a peripheral rim in a crown flange suitable for applying, in a plane of joins the upright edge of the diffuser on an annular seat of the base, a plurality of screws passing through passages in the flange to engage in threads of the base and thus tighten the edge of the diffuser on the annular reach of the base.

Une telle disposition est classique pour obtenir un joint étanche entre la portée annulaire de l'embase, garnie d'un anneau de joint, et la tranche du diffuseur, sans avoir à tenir le diffuseur directement par les vis, ce diffuseur, couramment en verre, ne supportant pas le serrage de têtes de vis sans risque de bris.Such an arrangement is conventional in order to obtain a tight seal between the annular bearing surface of the base, furnished with a seal ring, and the edge of the diffuser, without having to hold the diffuser directly by the screws, this diffuser, commonly made of glass. , not supporting the tightening of screw heads without risk of breakage.

Le document DE-B-1 029 928, qui décrit un hublot étanche différant notablement de l'invention, évoque un état de la technique correspondant sensiblement à ce qui est évoqué ci-dessus, à la différence que la bride est complétée par une protection grillagée.The document DE-B-1 029 928, which describes a watertight porthole differing notably from the invention, evokes a state of the art corresponding substantially to what is mentioned above, with the difference that the flange is completed by a protection screened.

Toutefois la mise en place du diffuseur sur l'embase, et l'engagement des vis dans les taraudages de l'embase demandent une certaine précision pour que l'on puisse obtenir un serrage équilibré des vis, nécessaire à l'étanchéité. Une vis engagée à force dans le taraudage met en échec l'étanchéité. On remarquera que les hublots d'éclairage non étanches ne requièrent pas une telle précision. Mais ils ne sont pas utilisables en locaux humides ou en extérieurs.However, the installation of the diffuser on the base, and the engagement of the screws in the threads of the base require a certain precision so that one can obtain a balanced tightening of the screws, necessary for sealing. A screw forced into the thread defeats the seal. It will be noted that the non-watertight lighting portholes do not require such precision. However, they cannot be used in damp rooms or outdoors.

Par ailleurs, pour éclairer efficacement, les hublots sont montés, soit au plafond, soit en parties hautes de parois verticales, et ne sont accessibles généralement qu'en montant sur un escabeau ou une échelle, où un opérateur a une position moins assurée qu'avec les deux pieds sur le sol. La tenue et la présentation précise du diffuseur sur l'embase exigent normalement deux mains, et, si la bride n'est pas fixée temporairement sur le diffuseur, la présentation correcte de cette pièce exige également deux mains. Enfin l'engagement et le serrage des vis requièrent normalement l'usage des deux mains. Le démontage du diffuseur est aussi exigeant.In addition, to effectively light, the portholes are mounted, either on the ceiling, or in high parts of vertical walls, and are generally accessible only by climbing a stepladder or a ladder, where an operator has a less secure position than with both feet on the ground. Holding and precisely presenting the diffuser on the base normally requires two hands, and, if the flange is not temporarily attached to the diffuser, the correct presentation of this part also requires two hands. Finally, the engagement and tightening of the screws normally require the use of two hands. Disassembly of the diffuser is also demanding.

Pour qu'un opérateur unique puisse mettre en place le diffuseur et le serrer convenablement, ou pour l'enlever, il doit préparer soigneusement son travail, s'assurer que tout le matériel, pièces et outils dont il aura besoin, sera accessible au moment voulu, et fréquemment procéder à des fixations provisoires, par exemple avec du ruban adhésif. Une fausse manoeuvre fréquemment oblige à reprendre l'opération dès le début. De toute façon la fermeture et l'ouverture du hublot s'exécutent en des temps qui apparaissent excessifs.For a single operator to put the diffuser in place and tighten it properly, or to remove it, he must carefully prepare his work, ensuring that all the equipment, parts and tools he will need will be accessible at the time. desired, and frequently make temporary fixings, for example with adhesive tape. A wrong move frequently forces you to resume the operation from the start. In any case, the closing and opening of the door is carried out in times which appear excessive.

Pour remédier à cet état de chose, l'invention propose un hublot étanche pour lampe d'éclairage, comprenant une embase porte-lampe à fixer sur une paroi, et un diffuseur translucide convexe avec une tranche dressée, tenu par un rebord périphérique entourant la tranche dressée dans une bride en couronne apte à appliquer, dans un plan de joint, la tranche dressée du diffuseur sur une portée annulaire de l'embase, une pluralité de vis traversant des passages dans la bride pour s'engager dans des taraudages de l'embase et ainsi serrer la tranche du diffuseur sur la portée annulaire, caractérisé en ce que la bride est munie de doigts intercalés entre des passages de vis, dirigés perpendiculairement au plan de joint dans une direction opposée à la convexité du diffuseur, et aptes à s'encliqueter dans des logements complémentaires ménagés dans l'embase, en sorte de maintenir la bride avec le diffuseur en position pour l'engagement des vis.To remedy this state of affairs, the invention proposes a watertight porthole for a lighting lamp, comprising a lamp-holder base to be fixed on a wall, and a convex translucent diffuser with an erect edge, held by a peripheral rim surrounding the edge erected in a crown flange suitable for applying, in a joint plane, the upright edge of the diffuser on an annular bearing surface of the base, a plurality of screws passing through passages in the flange to engage in threads of the '' base and thus tighten the edge of the diffuser on the annular surface, characterized in that the flange is provided with fingers interposed between screw passages, directed perpendicular to the joint plane in a direction opposite to the convexity of the diffuser, and suitable for snap into complementary housings in the base, so as to keep the flange with the diffuser in position for the engagement of the screws.

Ainsi, selon l'invention, il suffit de présenter le diffuseur et sa bride, tenus à deux mains, sur l'embase jusqu'à encliquetage des doigts dans leur logement dans l'embase pour se libérer les mains pour le serrage des vis.Thus, according to the invention, it suffices to present the diffuser and its flange, held with two hands, on the base until the fingers snap into their housing in the base to free their hands for tightening the screws.

En outre, en disposition préférée, le rebord périphérique du diffuseur présente, au passage des doigts de la bride, des encoches rectangulaires tandis que les logements complémentaires des doigts dans l'embase sont bordés par une paire de lames-cliquets, aptes à s'engager sur les côtés de l'encoche correspondante du rebord de diffuseur en sorte de maintenir celui-ci en position appropriée à la mise en place de la bride.In addition, in a preferred arrangement, the peripheral rim of the diffuser has, at the passage of the fingers of the flange, rectangular notches while the complementary housings of the fingers in the base are bordered by a pair of ratchet blades, suitable for engage on the sides of the corresponding notch on the flange of diffuser so as to keep it in the appropriate position for fitting the flange.

Cette disposition simplifie encore la fermeture du hublot, puisque l'on présente d'abord le diffuseur seul sur l'embase pour l'encliqueter par engagement des lames-cliquets dans les encoches, puis présenter la bride en engageant les doigts entre les lames-cliquets, et enfin mettre en place et serrer les vis, l'achèvement de chaque opération libérant les deux mains pour l'exécution de l'opération suivante.This arrangement further simplifies the closing of the window, since the diffuser is first presented alone on the base to snap it by engagement of the ratchet blades in the notches, then present the flange by engaging the fingers between the blades- pawls, and finally put in place and tighten the screws, the completion of each operation freeing both hands for the execution of the next operation.

D'autres caractéristiques et des avantages de l'invention ressortiront d'ailleurs de la description qui va suivre, à titre d'exemple, en référence aux dessins annexés dans lesquels :

  • la figure 1 est une vue en élévation, en coupe, d'un exemple de réalisation, où le diffuseur et la bride du hublot sont représentés à l'aplomb de l'embase, avant assemblage;
  • la figure 2 est une vue en élévation, en coupe, du hublot de la figure 1 après fermeture et avant engagement et serrage des vis de fixation;
  • la figure 3 est une vue de détail de la figure 2 après engagement et serrage des vis de fixation; et
  • la figure 4 est une vue partielle en coupe de la figure 2 selon IV-IV.
Other characteristics and advantages of the invention will emerge from the description which follows, by way of example, with reference to the appended drawings in which:
  • Figure 1 is an elevational view, in section, of an exemplary embodiment, where the diffuser and the porthole flange are shown directly above the base, before assembly;
  • Figure 2 is an elevational view, in section, of the window of Figure 1 after closing and before engagement and tightening of the fixing screws;
  • Figure 3 is a detail view of Figure 2 after engagement and tightening of the fixing screws; and
  • Figure 4 is a partial sectional view of Figure 2 along IV-IV.

Selon l'exemple choisi et représenté aux figures 1 à 4, le hublot comprend une embase porte-lampe 1, de forme générale circulaire, à fixer sur une paroi, un diffuseur translucide convexe 2 et une bride en couronne 3 prévue pour la fixation du diffuseur 2 sur l'embase 1.According to the example chosen and shown in Figures 1 to 4, the window comprises a lamp holder base 1, of generally circular shape, to be fixed on a wall, a translucent convex diffuser 2 and a crown flange 3 provided for fixing the diffuser 2 on base 1.

Une douille 5 est fixée sur l'embase 1 pour recevoir le culot 6A d'une lampe d'éclairage 6.A socket 5 is fixed to the base 1 to receive the base 6A of a lighting lamp 6.

De manière classique, un capot mobile 4 assure, lorsqu'il est en position fermée, la protection de la douille 5 et de ses connexions aux conducteurs d'alimentation 5a, tout en autorisant l'assujettissement du culot 6A de la lampe par un orifice de passage 12 pratiqué dans le capot 4.Conventionally, a movable cover 4 ensures, when in the closed position, the protection of the socket 5 and of its connections to the supply conductors 5 a , while allowing the subjection of the base 6A of the lamp by a passage orifice 12 formed in the cover 4.

Les caractéristiques du capot mobile 4 ne sont pas décrites ici plus en détail car elles ne concernent pas la présente invention.The characteristics of the movable cover 4 are not described here in more detail because they do not relate to the present invention.

Le diffuseur 2 comporte une partie centrale bombée avec sa face convexe se présentant à l'extérieur du hublot et une jupe 7 qui se projette dans la direction opposée à la convexité de cette partie centrale, et qui se termine par un rebord périphérique 11 dirigé radialement vers l'extérieur. La face externe de la jupe 7 est légèrement évasée vers l'extérieur pour garantir une zone de contact avec la bride 3 qui est en matériau souple. La tranche dressée 10 de la jupe 7 est apte à être appliquée, par l'intermédiaire de la bride 3, sur une portée annulaire 14 aménagée dans l'embase 1.The diffuser 2 comprises a curved central part with its convex face appearing outside the porthole and a skirt 7 which projects in the direction opposite to the convexity of this central part, and which ends in a peripheral rim 11 directed radially outwards. The external face of the skirt 7 is slightly flared towards the outside to guarantee a zone of contact with the flange 3 which is made of flexible material. The raised edge 10 of the skirt 7 is capable of being applied, by means of the flange 3, to an annular surface 14 arranged in the base 1.

La bride 3 présente la forme d'une couronne avec une paroi 18 inclinée qui, lorsque le hublot est monté, prolonge la partie centrale bombée du diffuseur 2. Comme représenté sur les figures 2 et 3, l'un des bords, 18A, de la paroi 18 vient alors au contact de l'embase 1 en A, tandis que l'autre bord 18B de la paroi 18 présente un retour 19, qui se projette dans la direction opposée à la convexité du diffuseur et qui vient au contact de la jupe 7 du diffuseur 2 en B, le rebord périphérique 11 se retrouvant alors emprisonné dans la bride 3.The flange 3 has the shape of a crown with an inclined wall 18 which, when the window is mounted, extends the domed central part of the diffuser 2. As shown in FIGS. 2 and 3, one of the edges, 18A, of the wall 18 then comes into contact with the base 1 at A, while the other edge 18B of the wall 18 has a return 19, which projects in the direction opposite to the convexity of the diffuser and which comes into contact with the skirt 7 of the diffuser 2 at B, the peripheral rim 11 then being trapped in the flange 3.

La fixation de la bride 3 s'opère par le serrage de vis 20 qui traversent des passages 21 pratiqués dans la bride et coopèrent avec des taraudages 22 prévus dans l'embase 1 (voir figure 3). Ces vis 20 sont ici au nombre de trois, les passages et taraudages correspondants étant disposés à distance égale les uns des autres respectivement dans la bride et l'embase.The fixing of the flange 3 takes place by tightening screws 20 which pass through passages 21 made in the flange and cooperate with threads 22 provided in the base 1 (see FIG. 3). There are three of these screws 20 here, the corresponding passages and threads being arranged at equal distance from each other respectively in the flange and the base.

Des ailettes de raidissement 28 assurent, de manière classique, une consolidation de la bride.Stiffening fins 28 ensure, in a conventional manner, a consolidation of the flange.

Conformément à l'invention, des moyens sont prévus pour permettre un assemblage du diffuseur et de la bride sur l'embase, et leur maintien en position, pour faciliter l'engagement et le serrage des vis de fixation 20.According to the invention, means are provided to allow an assembly of the diffuser and the flange on the base, and holding them in position, to facilitate engagement and tightening of the fixing screws 20.

Ces moyens comprennent des doigts 30, au nombre de trois, ménagés dans la bride 3, intercalés entre les passages 21. Ils se projettent perpendiculairement au plan de joint défini par la tranche dressée 10 du diffuseur portant sur la portée annulaire 14 de l'embase 1, dans une direction opposée à la convexité du diffuseur 2. L'extrémité des doigts 30 est conformée avec une saillie 31, formant cliquet, dirigée vers le centre de la bride 3.These means include fingers 30, three in number, formed in the flange 3, interposed between the passages 21. They project perpendicular to the joint plane defined by the raised edge 10 of the diffuser bearing on the annular bearing surface 14 of the base 1, in a direction opposite to the convexity of the diffuser 2. The end of the fingers 30 is shaped with a projection 31, forming a pawl, directed towards the center of the flange 3.

Chaque doigt 30 est destiné à venir s'engager et s'encliqueter dans un logement complémentaire 35 prévu dans l'embase 1, après avoir traversé des encoches rectangulaires 40 pratiquées dans le rebord périphérique 11 du diffuseur. Les logements complémentaires 35 sont au nombre de trois, intercalés entre les taraudages 22. Ils sont définis par l'espace situé entre l'embase 1 et la paroi sur laquelle est fixée l'embase. L'ouverture 33 par laquelle est engagé un doigt 30 présente des dimensions plus grandes que l'extrémité de ce dernier et l'encliquetage s'opère sur la face interne de l'embase sur le côté de cette ouverture 33 (voir figure 2).Each finger 30 is intended to engage and snap into a complementary housing 35 provided in the base 1, after having passed through rectangular notches 40 formed in the peripheral edge 11 of the diffuser. The complementary housings 35 are three in number, interposed between the threads 22. They are defined by the space located between the base 1 and the wall on which the base is fixed. The opening 33 through which a finger 30 is engaged has dimensions that are larger than the end of the latter and the latching takes place on the internal face of the base on the side of this opening 33 (see FIG. 2) .

Comme cela ressort mieux de la figure 4, des moyens sont prévus pour maintenir le diffuseur en position sur l'embase avant la mise en place de la bride pour faciliter encore plus la tâche de l'opérateur. A cet effet, chaque logement 35 est bordé par une paire de lames-cliquets 43A et 43B qui sont aptes à s'engager sur les côtés de l'encoche 40 du diffuseur correspondante. Ces lames-cliquets 43A et 43B s'étendent sensiblement dans des plans radiaux de l'embase 1 et présentent, sur leurs faces externes, des saillies 45A et 45B, de section en triangle sensiblement isocèle, qui portent sur les côtés opposés de l'encoche 40 au-delà du rebord périphérique 11 par rapport à l'embase 1.As is clear from FIG. 4, means are provided for holding the diffuser in position on the base before the installation of the flange to further facilitate the task of the operator. To this end, each housing 35 is bordered by a pair of ratchet blades 43A and 43B which are capable of engaging on the sides of the notch 40 of the corresponding diffuser. These pawl blades 43A and 43B extend substantially in radial planes of the base 1 and have, on their external faces, projections 45A and 45B, of substantially isosceles triangle section, which bear on the opposite sides of the notch 40 beyond the peripheral rim 11 relative to the base 1.

L'assemblage du diffuseur 2 et de la bride 3 sur l'embase 1 s'opère de la façon suivante.The assembly of the diffuser 2 and the flange 3 on the base 1 takes place as follows.

L'opérateur commence par coiffer l'embase 1 par le diffuseur 2 jusqu'à encliqueter les lames-cliquets 43A, 43B par les saillies 45A et 45B de l'embase 1 dans les côtés des encoches 40 du diffuseur 2 (des guides de montage, tels que 16, peuvent être prévus sur l'embase 1 pour faciliter cette opération). Les mains libres, l'opérateur procède ensuite à la mise en place de la bride 3 en encliquetant les doigts 30 dans les logements complémentaires 35 de l'embase entre les lames-cliquets 43A et 43B.The operator begins by covering the base 1 with the diffuser 2 until the ratchet blades 43A, 43B are engaged by the projections 45A and 45B of the base 1 in the sides of the notches 40 of the diffuser 2 (mounting guides , such as 16, can be provided on the base 1 to facilitate this operation). Hands free, the operator then proceeds to the establishment of the clamp 3 by snapping the fingers 30 into the complementary housings 35 of the base between the pawl blades 43A and 43B.

Il reste ensuite à engager les trois vis de fixation dans les passages correspondants de la bride 3. On peut prévoir ici des vis qui ne peuvent s'échapper de ces passages, pour faciliter encore la tâche de l'opérateur, qui peut procéder ensuite tranquillement à un serrage équilibré des vis pour garantir une bonne étanchéité du hublot.It then remains to engage the three fixing screws in the corresponding passages of the flange 3. We can provide here screws that can not escape from these passages, to further facilitate the task of the operator, who can then proceed quietly to a balanced tightening of the screws to guarantee a good sealing of the porthole.

Dans l'exemple de réalisation qui vient d'être décrit, des lames-cliquets de l'embase coopérant avec des perçages du diffuseur permettent avantageusement un montage successif du diffuseur puis de la bride, mais il va de soi que ces lames-cliquets peuvent être supprimées, la mise en place du diffuseur et son maintien s'opérant simultanément à celle de la bride, les doigts munis de cliquets de la bride coopérant avec les perçages aménagés sur le rebord périphérique du diffuseur.In the embodiment which has just been described, ratchet blades of the base cooperating with holes in the diffuser advantageously allow successive mounting of the diffuser and then of the flange, but it goes without saying that these ratchet blades can be removed, the establishment of the diffuser and its maintenance taking place simultaneously with that of the flange, the fingers provided with pawls of the flange cooperating with the holes provided on the peripheral rim of the diffuser.

Claims (6)

  1. A sealed surface-mounted light for a lighting lamp, comprising a lamp-carrying base (1) to be fixed to a wall, and a translucent convex diffuser (2) with a trued edge face (10), the diffuser being held by a peripheral rim (11) surrounding the trued edge face (10) in an annular flange member (3) capable of applying, in a joint plane, the trued edge face (10) of the diffuser against an annular bearing surface (14) of the base (1), a plurality of screws (20) passing through passages (21) in the flange member (3) to engage into screwthreads (22) in the base (1) and thus clamp the edge face (10) of the diffuser (2) against the annular bearing surface (14), characterised in that the flange member (3) is provided with fingers (30) which are interposed between screw passages (21), directed perpendicularly to the joint plane in a direction opposite to the convexity of the diffuser, and capable of latching into complementary housings (35) provided in the base (1), so as to hold the flange member (3) with the diffuser (2) in position for engagement of the screws (20).
  2. A surface-mounted light according to claim 1 characterised in that the peripheral rim (11) of the diffuser (2) has rectangular notches (40) where the fingers (30) of the flange member pass while the complementary housings (35) for said fingers (30) are bordered by a pair of latch blades (43A, 43B) capable of engaging against the sides of the corresponding notch (40) of the rim (11) of the diffuser (2) so as to hold the latter in the appropriate position for setting the flange member (3) in place.
  3. A surface-mounted light according to claim 2 characterised in that the latch blades (43A, 43B), extending substantially in radial planes of the base (1), have on their outside faces projections (45A, 45B) whose cross-section is in the form of a substantially isosceles triangle, which bear against the sides of notches, beyond the peripheral rim (11) with respect to the base (1).
  4. A surface-mounted light according to any one of claims 1 to 3 characterised in that the base (1) and the flange member (3) are generally circular.
  5. A surface-mounted light according to any one of claims 1 to 4 characterised in that the fingers (30) and the screw passages (21) in the flange member (3) are three in number respectively.
  6. A surface-mounted light according to any one of claims 1 to 5 characterised in that the screws (20) are so arranged that they cannot escape from the passages (21) in the flange member (3).
