Description

L'invention a pour objet les systèmes d'éclairage et en particulier les systèmes d'éclairage d'objets exposés par accrochage sur des murs.The invention relates to lighting systems and in particular the lighting systems of objects exposed by hanging on walls.

On connaît des systèmes d'accrochage de tableaux ou autres ouvrages d'art, le long de tiges de suspension accrochées à un profilé de cimaise. La tige de suspension, également appelée tige de cimaise, peut être déplacée suivant une direction horizontale le long du profilé de cimaise. Un crochet mobile verticalement le long de la tige, une fois bloqué par rapport au déplacement vertical, permet d'accrocher l'objet, par exemple un tableau. La position du tableau peut être ajustée en déplaçant la tige le long du profilé de cimaise ou en déplaçant verticalement le crochet. En revanche, le système d'éclairage associé, qui est généralement fixé au mur, est plus délicat à déplacer. Il faut, en général, percer de nouveaux trous dans le mur, ce qui est à la fois fastidieux et abîme le mur.Tables hanging systems or other structures are known, along suspension rods hung on a profile of chair rail. The suspension rod, also called rod chair, can be moved in a horizontal direction along the molding rail. A hook movable vertically along the rod, once blocked relative to the vertical movement, allows to hang the object, for example a table. The table position can be adjusted by moving the rod along the rail or by moving the hook vertically. On the other hand, the associated lighting system, which is usually wall mounted, is more difficult to move. In general, you have to drill new holes in the wall, which is both tedious and damaging the wall.

Pour permettre de déplacer l'éclairage en même temps que le tableau, un support pour lampe coulissant le long de la tige existe, connu sous le nom de "crochet Boyer pour réflecteur". Le dispositif est composé d'un premier tube faisant glissière le long de la tige de cimaise, d'un second tube d'assemblage assemblé sur le premier par une génératrice, d'un troisième tube fendu assemblé sur le second, parallèlement aux deux premiers. Le troisième tube est dimensionné pour y insérer un col de lampe. Sur une génératrice de ce troisième tube est soudée une portion de barre métallique recourbée en crochet soudée à mi-hauteur du troisième tube.To allow the lighting to be moved together with the board, there is a sliding lamp stand along the stem, known as a "Boyer Reflector Hook". The device is composed of a first tube sliding along the rod of chair rail, a second assembly tube assembled on the first by a generator, a third split tube assembled on the second, parallel to the first two . The third tube is sized to insert a lamp collar. On a generator of this third tube is welded a portion of metal bar curved hook welded halfway up the third tube.

On peut ainsi déplacer, simultanément, l'objet suspendu au crochet, et la lampe. Cependant, ce système déporte le crochet à une distance non négligeable vers l'avant de la tige -en avant de la tige par rapport au mur-, ce qui peut être un handicap en fonction de l'inclinaison que l'on souhaite tolérer pour un tableau par exemple. En outre, ce dispositif doit obligatoirement être assemblé sur des tiges à section carrée ou rectangulaire, afin d'assurer un moment de maintien évitant une rotation non souhaitée autour de la verticale, car le bras de levier entre l'axe de la tige et l'axe du col de la lampe est élevé.We can move simultaneously, the object hanging from the hook, and the lamp. However, this system moves the hook at a non-negligible distance forward of the rod -in front of the rod relative to the wall-, which can be a handicap depending on the inclination that one wishes to tolerate for a table for example. In in addition, this device must necessarily be assembled on rods with square or rectangular section, to ensure a holding moment avoiding unwanted rotation around the vertical, because the lever arm between the axis of the rod and the Lamp neck axis is high.

Même ainsi, le poids de la lampe et de l'objet à soutenir, du fait de leur déport en avant du mur, peut provoquer une déviation de l'objet à exposer et/ou risque d'abîmer la liaison entre la tige et le profilé de cimaise.Even so, the weight of the lamp and the object to be supported, because of their displacement in front of the wall, may cause a deviation of the object to be exposed and / or may damage the connection between the rod and the object. profile of picture rail.

L'invention a pour but de proposer un support pour éclairage qui soit facilement déplaçable en même temps que l'objet à exposer, qui assure une bonne stabilité de l'objet et une qualité constante de l'éclairage pour tous les objets similaires accrochés, et qui limite les efforts exercés sur la liaison entre tige et profilé de cimaise.The object of the invention is to provide a support for lighting that is easily movable together with the object to be exposed, which ensures a good stability of the object and a constant quality of the lighting for all similar objects hung, and which limits the forces exerted on the connection between rod and profile of chair rail.

A cette fin, l'invention propose un support tubulaire pour dispositif d'éclairage, comprenant au moins une première portion tubulaire formant glissière, et apte à coulisser suivant un premier axe le long d'une tige, comprenant au moins une seconde portion tubulaire sensiblement parallèle à la première portion tubulaire, et apte à accueillir une partie du dispositif d'éclairage, le support comportant un crochet dans lequel peut être inséré une boucle ou un cordon de suspension d'un élément à exposer. L'espace intérieur au crochet est disposé au moins pour partie dans le prolongement axial de ladite partie du dispositif d'éclairage. Par première et seconde portions tubulaires, on entend ici des portions du support comprenant chacune un espace intérieur d'insertion ou de guidage, l'espace intérieur étant délimité par une ou plusieurs portions de parois délimitées par des surfaces réglées définies par des droites génératrices toutes parallèles au premier axe. La portion tubulaire peut être par exemple une portion de matière avec un perçage cylindrique -cylindre au sens large, non limité au cylindre de révolution- ou être un ensemble de languettes repliées autour d'un espace cylindrique. Les projections axiales, -c'est-à-dire les projections suivant le premier axe, sur un plan perpendiculaire au premier axe- des espaces intérieurs de la première et de la seconde portion tubulaire, sont distincts et ne présentent pas de zone commune. En position assemblée, la tige est suspendue par une de ses extrémités, et l'axe de la tige, qui correspond au premier axe, est donc sensiblement vertical. Le dispositif d'éclairage est de préférence une lampe à col, et la seconde partie tubulaire est configurée pour y insérer une extrémité du col de la lampe. Le col de la lampe part du support de préférence parallèlement à la tige, puis peut être recourbé, de préférence dans la direction correspondant à l'avant du crochet -c'est-à-dire vers le côté ouvert du crochet. Lorsque le dispositif d'éclairage est assemblé sur le support, l'espace intérieur au crochet, conçu pour maintenir une portion du cordon d'accrochage, est disposé au moins pour partie dans le prolongement axial du col de lampe, par exemple en dessous du col de lampe. L'extrémité insérée de la lampe est de préférence une extrémité inférieure du col de la lampe, mais on peut envisager une variante de réalisation dans laquelle, notamment si la tige est de type rigide, le crochet est disposé au dessus de la seconde portion cylindrique, le col de la lampe étant inséré par en dessous dans le support et venant se recourber par en dessous vers l'objet à éclairer. Le crochet est orienté pour retenir l'objet suspendu sous l'effet de son poids, donc de manière à pouvoir y insérer un cordon de haut en bas, et est orienté de manière à permettre d'appuyer le cordon sur une surface de fond de crochet.To this end, the invention proposes a tubular support for a lighting device, comprising at least a first tubular portion forming a slide, and capable of sliding along a first axis along a rod, comprising at least a second tubular portion substantially parallel to the first tubular portion, and adapted to accommodate a portion of the lighting device, the support having a hook into which can be inserted a loop or a suspension cord of an element to be exposed. The interior space at the hook is arranged at least partly in the axial extension of said portion of the lighting device. By first and second tubular portions, here means portions of the support each comprising an interior space for insertion or guiding, the interior space being delimited by one or more portions of walls delimited by regulated surfaces defined by generating lines all parallel to the first axis. The tubular portion may be for example a portion of material with a cylindrical bore-cylinder in the broad sense, not limited to the cylinder of revolution- or be a set of tabs folded around a cylindrical space. The axial projections, that is to say the projections along the first axis, on a plane perpendicular to the first axis of the interior spaces of the first and second tubular portions, are distinct and do not show common area. In the assembled position, the rod is suspended by one of its ends, and the axis of the rod, which corresponds to the first axis, is therefore substantially vertical. The lighting device is preferably a neck lamp, and the second tubular portion is configured to insert one end of the neck of the lamp. The neck of the lamp preferably extends from the support parallel to the stem, and then can be bent, preferably in the direction corresponding to the front of the hook-that is, toward the open side of the hook. When the lighting device is assembled on the support, the interior space of the hook, designed to hold a portion of the hooking cord, is arranged at least partly in the axial extension of the lamp neck, for example below the lamp collar. The inserted end of the lamp is preferably a lower end of the neck of the lamp, but it is possible to envisage a variant embodiment in which, particularly if the rod is of rigid type, the hook is disposed above the second cylindrical portion , the neck of the lamp being inserted from below into the support and coming to curl from below towards the object to be illuminated. The hook is oriented to retain the suspended object under the effect of its weight, so that it can insert a cord from top to bottom, and is oriented to allow to press the cord on a bottom surface of hook.

De manière avantageuse, la tige est une tige verticale de suspension avec une extrémité d'accrochage complémentaire d'un profil de cimaise, et est adaptée à recevoir aussi bien le support tubulaire, que d'autres types de crochets de suspension pour cadre de tableau, ou pour autres objets d'exposition. La tige peut être rigide, de préférence rectiligne. La tige peut être un support filaire vertical flexible, par exemple de type câble ou fil, métallique ou en d'autres matières. Lorsque la tige est flexible, la position du crochet sous le col de la lampe contribue sensiblement au maintien de la première portion tubulaire dans l'alignement de l'axe de la tige, c'est-à-dire de la verticale. Les directions mentionnées s'entendent quand le support est en position montée sur une tige verticale. Par abus de langage, on désigne ici par direction verticale la direction de la tige suspendue sur laquelle est assemblé le support, même si cette tige peut éventuellement se positionner légèrement en oblique par rapport à un mur vertical sur lequel est fixé un profilé de cimaise supportant la partie haute de la tige fixée au mur. Le positionnement du crochet sous le col de lampe permet d'assurer un bon alignement vertical entre le tableau -ou l'objet à suspendre- et l'éclairage assuré par la lampe.Advantageously, the rod is a vertical suspension rod with a hanging end complementary to a chair rail profile, and is adapted to receive both the tubular support, and other types of hanging hooks for a picture frame , or for other exhibits. The rod may be rigid, preferably rectilinear. The rod may be a flexible vertical wire support, for example cable or wire type, metal or other materials. When the rod is flexible, the position of the hook under the neck of the lamp contributes substantially to maintaining the first tubular portion in alignment with the axis of the rod, that is to say the vertical. The directions mentioned are understood when the support is in position mounted on a vertical rod. By abuse of language, here is meant by vertical direction the direction of the rod suspended on which is assembled the support, even if this rod can possibly be positioned slightly obliquely with respect to a vertical wall on which is fixed a molding rail supporting the upper part of the rod fixed to the wall. The positioning of the hook under the lamp collar ensures a good vertical alignment between the table -or the object to be suspended- and the illumination provided by the lamp.

Avantageusement, l'extérieur du support comporte, d'un côté opposé à l'ouverture du crochet, au moins une portion d'appui parallèle au premier axe. La portion d'appui peut être une ligne d'appui parallèle au premier axe, par exemple une génératrice d'un corps cylindrique formant le support. De manière préférentielle, la portion d'appui est une portion de surface plane.Advantageously, the outside of the support comprises, on a side opposite to the opening of the hook, at least one bearing portion parallel to the first axis. The bearing portion may be a bearing line parallel to the first axis, for example a generatrix of a cylindrical body forming the support. Preferably, the bearing portion is a flat surface portion.

Selon un mode de réalisation préféré, la distance horizontale maximale entre la portion, sensiblement verticale, d'appui et l'avant du crochet est inférieure ou égale à la largeur horizontale maximale du support. De cette manière, on limite le bras de levier des efforts que l'objet à suspendre peut exercer sur le support pour le faire tourner autour d'un axe vertical, pendant la mise en suspension de l'objet, et une fois que l'objet est suspendu en place. Par distance maximale entre la portion verticale d'appui et l'avant du crochet on entend la distance horizontale maximale entre la surface d'appui et une des surfaces délimitant l'intérieur du crochet.According to a preferred embodiment, the maximum horizontal distance between the substantially vertical support portion and the front of the hook is less than or equal to the maximum horizontal width of the support. In this way, the lever arm is limited by the forces that the object to be suspended can exert on the support to rotate it about a vertical axis, during the suspension of the object, and once the object is suspended in place. By maximum distance between the vertical support portion and the front of the hook means the maximum horizontal distance between the bearing surface and one of the surfaces defining the inside of the hook.

Le support peut comporter au moins une portion verticale et plane d'appui, sur l'extérieur du support du côté opposé à l'ouverture du crochet, la distance minimale entre cette portion d'appui et l'intérieur du crochet étant inférieure ou égale à deux fois la largeur maximale selon l'horizontale, de la portion d'appui. De cette manière la portion d'appui peut exercer un moment de maintien efficace pour éviter la rotation du support autour d'un axe vertical. Par verticale on entend ici une direction parallèle à l'axe de la glissière. Par horizontale on entend une direction perpendiculaire au premier axe. Par distance minimale entre la portion d'appui et l'intérieur du crochet, on entend la distance minimale entre la portion d'appui et une des surfaces -à l'arrière du crochet- délimitant l'intérieur du crochet.The support may comprise at least one vertical and flat bearing portion, on the outside of the support on the opposite side to the opening of the hook, the minimum distance between this bearing portion and the inside of the hook being less than or equal to at twice the maximum width according to the horizontal, of the support portion. In this way the support portion can exert an effective holding moment to prevent rotation of the support about a vertical axis. By vertical means here a direction parallel to the axis of the slide. Horizontal means a direction perpendicular to the first axis. Minimum distance between the support portion and the inside of the hook means the minimum distance between the bearing portion and one of the surfaces -a rear of the hook- delimiting the inside of the hook.

Selon un mode de réalisation préférentiel, la ou les première(s) portion(s) tubulaire(s) formant glissière, la ou les secondes portion(s) tubulaires de maintien du col et le crochet font partie d'une même pièce monobloc.According to a preferred embodiment, the first (s) portion (s) forming slider, the second or second portion (s) retaining the collar and the hook are part of the same piece.

Par exemple, le support comprend un élément monobloc de contour extérieur sensiblement cylindrique -cylindre de révolution ou cylindre ayant une section droite non circulaire- de génératrices parallèles au premier axe. Selon un mode de réalisation préféré, le cylindre a une section droite circulaire tronquée localement par une portion de droite, la portion de droite correspondant à la projection de la surface plane d'appui. Le support cylindrique peut être percé sur toute la longueur du cylindre par la glissière, et être percé sur une partie de sa longueur par un logement apte à accueillir une extrémité du col de la lampe. La surface d'appui, la glissière et le logement du col de lampe sont centrés tous trois sur un même plan de symétrie, c'est-à-dire sont disposés de manière à être chacun symétrique par rapport à ce plan. La glissière est disposée entre la surface plane et le logement pour col de lampe. En position assemblée, le plan de symétrie correspond typiquement à un plan vertical perpendiculaire à un mur sur lequel on a suspendu la tige-au moyen par exemple d'un profilé de cimaise fixé sur le mur. La surface d'appui permet d'appuyer le support sur le mur en répartissant les efforts d'appui (par rapport à un appui ponctuel ou linéaire) et contribue à limiter la rotation du support par rapport au mur. Cette rotation peut être modérée si la tige est en matériau rigide (par exemple en acier) et présente une section de forme résistante à la torsion. Cette rotation risque d'être plus importante, en l'absence de surface d'appui, si la tige présente une section réduite (fil), une section dont une dimension est sensiblement inférieure à l'autre (ruban de suspension), si elle est réalisée en matériau de faible module d'Young (matière polymères) ou si elle est de type tressé (câble ou fil de suspension).For example, the support comprises a one-piece element of substantially cylindrical outer contour-cylinder of revolution or cylinder having a non-circular cross section of generatrices parallel to the first axis. According to a preferred embodiment, the cylinder has a circular cross section truncated locally by a right portion, the right portion corresponding to the projection of the flat bearing surface. The cylindrical support can be drilled over the entire length of the cylinder by the slide, and be pierced over part of its length by a housing adapted to accommodate one end of the neck of the lamp. The bearing surface, the slide and the housing of the lamp neck are all centered on the same plane of symmetry, that is to say are arranged so as to be each symmetrical with respect to this plane. The slide is disposed between the flat surface and the lamp-neck housing. In the assembled position, the plane of symmetry typically corresponds to a vertical plane perpendicular to a wall on which the rod has been suspended, for example by means of a wall rail profile fixed to the wall. The support surface makes it possible to support the support on the wall by distributing the support forces (relative to a point or linear support) and contributes to limiting the rotation of the support relative to the wall. This rotation can be moderate if the rod is made of rigid material (for example steel) and has a shape section resistant to torsion. This rotation may be greater, in the absence of a bearing surface, if the rod has a reduced section (wire), a section of which one dimension is substantially smaller than the other (suspension tape), if it is made of low Young's modulus material (polymeric material) or if it is of braided type (cable or suspension wire).

Le support cylindrique est par exemple entaillé par une entaille sensiblement plane, oblique par rapport au premier axe, et perpendiculaire par rapport au plan de symétrie, de manière à définir un évidement formant l'intérieur du crochet, tourné à l'opposé de la surface plane d'appui.The cylindrical support is for example cut by a notch substantially plane, oblique with respect to the first axis, and perpendicular to the plane of symmetry, so as to define a recess forming the inside of the hook, turned away from the flat bearing surface.

D'autres variantes de supports monoblocs présentant les caractéristiques dimensionnelles précédentes sont envisageables, par exemple un support réalisé à partir d'une tôle découpée pliée. Dans cette variante de réalisation, des languettes horizontales de tôle peuvent sertir le col de lampe d'un côté du plan de découpe initial de la tôle. D'autres languettes horizontales peuvent entourer la glissière de l'autre côté du plan de découpe initial de la tôle, et une languette de tôle découpée perpendiculairement aux précédentes peut être recourbée pour former un crochet sous le col de lampe.Other variants of one-piece supports having the preceding dimensional characteristics are conceivable, for example a support made from a folded cut sheet metal. In this variant embodiment, horizontal tabs of sheet metal can crimp the lamp neck on one side of the initial cutting plane of the sheet. Other horizontal tabs may surround the slideway on the other side of the original cutting plane of the sheet, and a sheet metal tongue cut perpendicularly to the previous ones may be bent to form a hook under the lamp collar.

Avantageusement, le support comporte un moyen de serrage radial -serrage suivant au moins une direction appartenant à un plan perpendiculaire au premier axe- traversant la pièce monobloc et permettant de bloquer les mouvements, notamment les mouvements verticaux, du support par rapport à la tige. Les moyens de serrage radiaux peuvent être une ou plusieurs vis traversant la portion formant glissière pour venir en appui sur la tige.Advantageously, the support comprises a radial clamping means -serrage following at least one direction belonging to a plane perpendicular to the first axis-through the one-piece piece and for blocking the movements, including vertical movements, of the support relative to the rod. The radial clamping means may be one or more screws passing through the slider portion to bear on the rod.

De manière préférentielle, en position assemblée sur la tige, la plus grande dimension du support est sa dimension verticale, qui est au moins le double de la plus grande dimension du support selon l'horizontale. En outre, selon un mode de réalisation particulièrement avantageux, la longueur axiale de la glissière s'étend sur toute la longueur d'insertion du col de lampe et sur toute la longueur verticale du crochet. Chacune des deux dernières caractéristiques contribue à un maintien efficace du col de lampe pour éviter qu'il ne s'écarte outre mesure de la verticale.Preferably, in the assembled position on the rod, the largest dimension of the support is its vertical dimension, which is at least twice the largest dimension of the support according to the horizontal. In addition, according to a particularly advantageous embodiment, the axial length of the slide extends over the entire insertion length of the lamp collar and over the entire vertical length of the hook. Each of the last two features contributes to effective maintenance of the lamp collar to prevent it from deviating excessively from the vertical.

De manière préférentielle, l'intérieur du crochet est délimité au moins pour partie par deux faces planes sensiblement parallèles entre elles, ou formant un dièdre, les deux faces étant perpendiculaires au plan de symétrie du support. Les deux faces planes sont reliées par une surface de fond de crochet. En position assemblée, on peut considérer que l'intérieur du crochet est délimité au moins pour partie par deux faces planes de directions proches de la verticale, reliées par une surface de fond de crochet. Par sensiblement verticales, on entend des faces formant un angle nul ou faible -par exemple inférieur ou égal à 30°- avec la direction verticale. Selon un mode de réalisation avantageux, au moins une des faces planes, de préférence la face la plus proche de la portion d'appui, se prolonge en partie supérieure par une portion de surface oblique de rétention de l'élément d'attache filaire. La portion de surface oblique surplombe de préférence l'ouverture du crochet. Selon un mode de réalisation préféré, la surface oblique forme en même temps une surface de guidage d'insertion de l'élément filaire de rétention. Le crochet s'ouvre de préférence vers l'extrémité axiale du support dans laquelle est inséré le col de lampe.Preferably, the inside of the hook is delimited at least partly by two plane faces substantially parallel to each other, or forming a dihedron, the two faces being perpendicular to the plane of symmetry of the support. The two flat faces are connected by a hook bottom surface. In the assembled position, it can be considered that the interior of the hook is delimited at least partly by two plane faces of directions close to the vertical, connected by a hook background surface. By substantially vertical, we mean faces forming a zero or low angle-for example less than or equal to 30 ° -with the vertical direction. According to an advantageous embodiment, at least one of the flat faces, preferably the face closest to the support portion, is extended in the upper part by an oblique surface portion of retention of the wire fastener element. The oblique surface portion preferably overhangs the opening of the hook. According to a preferred embodiment, the oblique surface forms at the same time an insertion guide surface of the retention wire element. The hook preferably opens towards the axial end of the support in which is inserted the lamp neck.

Selon un mode de réalisation préféré, le système d'éclairage comprend une lampe à col dont la base du col est insérée dans la seconde portion tubulaire. La lampe comprend une rampe d'éclairage sensiblement perpendiculaire à l'extrémité du col qui tient la rampe. Autrement dit, la rampe de la lampe s'étend suivant une direction horizontale en position assemblée du système.According to a preferred embodiment, the lighting system comprises a neck lamp whose base of the neck is inserted into the second tubular portion. The lamp comprises a lighting ramp substantially perpendicular to the end of the neck which holds the ramp. In other words, the ramp of the lamp extends in a horizontal direction in the assembled position of the system.

Avantageusement, la ligne moyenne du col de lampe se trouve dans le plan de symétrie.Advantageously, the average line of the lamp collar is in the plane of symmetry.

Avantageusement, la rampe est articulée par rapport au col pour pouvoir pivoter autour d'un axe perpendiculaire au plan de symétrie. En position assemblée du support, cet axe perpendiculaire est un axe horizontal.Advantageously, the ramp is articulated relative to the neck to be able to pivot about an axis perpendicular to the plane of symmetry. In the assembled position of the support, this perpendicular axis is a horizontal axis.

La rampe d'éclairage peut être mobile par exemple grâce à une articulation du type rotule entre un col rigide et la rampe, grâce à une articulation simple avec un seul axe de rotation, ou du fait de la présence d'une portion articulée du col en partie supérieure du col.The lighting ramp may be movable for example by virtue of a ball joint type articulation between a rigid neck and the ramp, thanks to a simple articulation with a single axis of rotation, or because of the presence of an articulated portion of the neck in the upper part of the collar.

La rampe d'éclairage peut comporter une ou plusieurs LED, alimentées par exemple par un transformateur à partir du réseau électrique, ou alimentées par exemple par une ou plusieurs piles électriques (aussi appelées "accumulateurs électriques").The lighting ramp may comprise one or more LEDs, fed for example by a transformer from the electrical network, or supplied for example by one or more electric batteries (also called "electric accumulators").

Le système peut en outre comprendre une tige de suspension de section adaptée à la forme de la glissière, ainsi qu'un profilé de cimaise de forme complémentaire à une forme d'accrochage ménagée en partie supérieure de la tige d'accrochage.The system may further comprise a suspension rod of section adapted to the shape of the slide, and a profile of chair rail complementary shape to a hooking shape formed in the upper part of the attachment rod.

Selon un mode particulier de réalisation, le système d'éclairage comprend un profilé de cimaise, et comprend une tige de cimaise d'extrémité complémentaire d'un rail du profilé de cimaise, la tige étant apte à être suspendue en accrochant son extrémité dans le rail, le rail comportant au moins deux contacts d'alimentation électrique placés de manière à venir en contact avec deux portions, électriquement isolées l'une de l'autre, de l'extrémité de la tige.According to a particular embodiment, the lighting system comprises a profile of chair rail, and comprises an end of chair rail complementary to a rail of the chair rail profile, the rod being able to be suspended by hanging its end in the rail, the rail having at least two power supply contacts placed so as to come into contact with two portions, electrically insulated from each other, of the end of the rod.

Selon les variantes de réalisation, les contacts électriques peuvent s'étendre le long du rail du profilé de cimaise, être ponctuels, ou former deux groupes de contacts de polarités différentes distribués de part et d'autre du rail. L'alimentation de la lampe par la tige de suspension est en particulier envisageable si l'éclairage de la rampe est assuré au moyen de LED, qui peuvent être alimentées en basse tension.According to the alternative embodiments, the electrical contacts may extend along the rail of the molding rail, be punctual, or form two groups of contacts of different polarities distributed on either side of the rail. The supply of the lamp by the suspension rod is in particular possible if the lighting of the ramp is provided by means of LEDs, which can be supplied with low voltage.

Dans ce mode de réalisation, le support peut comprendre un système de connexion comprenant, d'une part, un premier élément de contact électrique ayant un contact glissant avec une première zone de la tige, et relié à un premier contact électrique de la lampe, et comprenant d'autre part, un second élément de contact ayant un contact glissant avec une seconde zone de la tige, isolée électriquement de la première zone, et relié à un second contact électrique de la lampe.In this embodiment, the support may comprise a connection system comprising, on the one hand, a first electrical contact element having a sliding contact with a first zone of the rod, and connected to a first electrical contact of the lamp, and further comprising, a second contact member having a sliding contact with a second zone of the rod, electrically isolated from the first zone, and connected to a second electrical contact of the lamp.

Comme illustré sur la figure 1, le système d'éclairage et de suspension selon l'invention comprend un profilé de cimaise 11 assemblé en position horizontale à un mur. Le profilé de cimaise 11 forme un rail auquel est accrochée une partie supérieure 22, recourbée, d'une tige de suspension 12. L'axe de la tige 12 s'étend suivant une direction x-x' que l'on désigne ici, pour simplifier la description et par abus de langage, comme « direction verticale » -bien que cette tige puisse être légèrement inclinée par rapport au mur-. On considère dans la description que la tige est suspendue de manière à être parallèle au mur, c'est-à-dire verticale.As illustrated on the figure 1 , the lighting and suspension system according to the invention comprises a molding rail 11 assembled in a horizontal position to a wall. The molding rail profile 11 forms a rail to which is attached an upper portion 22, curved, a suspension rod 12. The axis of the rod 12 extends in a direction xx 'that is designated here, to simplify description and misuse of language, such as "vertical direction" -though this rod may be slightly inclined relative to the wall-. It is considered in the description that the rod is suspended so as to be parallel to the wall, that is to say vertical.

Sur la tige 12, est assemblé un support 1 configuré pour pouvoir coulisser verticalement le long de la tige 12, et pour pouvoir être bloqué ensuite le long de cette tige 12 par des vis 24 traversant le corps du support et venant en appui contre la tige 12. Le support 1 est percé d'un orifice 14 faisant office de glissière pour la tige 12, et est percé sur une partie supérieure de sa longueur, par un logement 15 dans lequel est inséré le col 3 d'une lampe 2.On the rod 12, is assembled a support 1 configured to be able to slide vertically along the rod 12, and then to be blocked along the rod 12 by screws 24 passing through the body of the support and bearing against the rod 12. The support 1 is pierced with an orifice 14 acting as a slide for the rod 12, and is pierced over an upper part of its length, by a housing 15 in which is inserted the neck 3 of a lamp 2.

L'extrémité supérieure du col 3 de la lampe porte une rampe d'éclairage 4. La rampe d'éclairage 4 peut être articulée, par exemple au moyen d'une articulation 5 de type rotule, comme illustré sur la figure 1, pour pouvoir tourner par rapport à une direction horizontale, voire par rapport à deux directions. Selon une autre variante de réalisation, le col 3 de la lampe peut lui-même être articulé de manière à changer sa courbe et son orientation dans l'espace, afin de démultiplier les positions possibles pour la rampe d'éclairage 4.The upper end of the neck 3 of the lamp carries a lighting ramp 4. The lighting ramp 4 can be articulated, for example by means of a ball-type articulation 5, as shown in FIG. figure 1 , to be able to rotate relative to a horizontal direction, or even with respect to two directions. According to another variant embodiment, the neck 3 of the lamp can itself be articulated so as to change its curve and its orientation in space, in order to multiply the possible positions for the lighting ramp 4.

La rampe d'éclairage 4 peut s'étendre selon une direction horizontale de part et d'autre de l'extrémité du col 3 de la lampe. Elle peut comporter une ou plusieurs LEDs (Light Emitting Devices) permettant un éclairage à basse consommation et une longue durée de vie de la lampe.The lighting ramp 4 may extend in a horizontal direction on either side of the end of the neck 3 of the lamp. It can include one or more LEDs (Light Emitting Devices) allowing for low consumption lighting and long lamp life.

L'alimentation des LEDs peut être assurée au moyen d'un transformateur 7 configuré pour être branché sur un réseau électrique (non représenté) et relié à la lampe 2 par des fils 6 d'alimentation émergeant de préférence de la partie inférieure du support 1.The LEDs can be supplied by means of a transformer 7 configured to be connected to an electrical network (not shown) and connected to the lamp 2 by supply wires 6 preferably emerging from the lower part of the support 1 .

Le transformateur 7 peut être muni d'un interrupteur 8 permettant d'allumer et d'éteindre la lampe. L'interrupteur peut également se trouver au niveau du col de la lampe, ou le long du fil d'alimentation 6.The transformer 7 may be provided with a switch 8 for turning the lamp on and off. The switch can also be located at the neck of the lamp, or along the supply wire 6.

Le support 1 comprend une portion inférieure formant un crochet 17. L'ouverture du crochet 17 est tournée vers l'avant du support par rapport au mur. L'ouverture du crochet 17 est dirigée vers le haut de manière à pouvoir y insérer un cordon, un câble 9 ou une boucle de suspension d'une oeuvre d'art 10.The support 1 comprises a lower portion forming a hook 17. The opening of the hook 17 is turned towards the front of the support relative to the wall. The opening of the hook 17 is directed upwards so as to be able to insert a cord, a cable 9 or a suspension loop of a work of art 10.

Sur la figure 1, on a ainsi représenté un cadre 10 de tableau dont le cordon 9 est inséré à l'intérieur du crochet 17, le col 3 de la lampe 2 s'étendant vers le haut à partir du support 1, et la lampe 2 venant éclairer par en haut le tableau porté par le cadre 10.On the figure 1 a picture frame 10 has been shown in which the cord 9 is inserted inside the hook 17, the neck 3 of the lamp 2 extending upwards from the support 1, and the lamp 2 illuminating by at the top the picture carried by the frame 10.

La figure 2 est une vue de côté du support 1 de la figure 1. La figure 3 est une vue de dessus du support 1 de la figure 1. On retrouve sur les figures 2 et 3 des éléments communs à la figure 1, les mêmes éléments étant désignés par les mêmes références. On retrouve en particulier l'orifice 14 faisant office de glissière pour la tige, qui peut être de section ronde, rectangulaire ou carrée, un logement pour col 15, qui s'étend de préférence uniquement en partie supérieure du support, afin de ménager, en partie inférieure du support, l'espace nécessaire pour l'évidement 17 faisant office de crochet.The figure 2 is a side view of the support 1 of the figure 1 . The figure 3 is a top view of the support 1 of the figure 1 . We find on Figures 2 and 3 elements common to the figure 1 , the same elements being designated by the same references. There is in particular the orifice 14 acting as slide for the rod, which may be of round, rectangular or square section, a housing for neck 15, which preferably extends only in the upper part of the support, to spare, in the lower part of the support, the space required for the recess 17 acting hook.

Le support 1 comporte ici un corps 13 globalement cylindrique. Le corps 13, dans le cas illustré, a globalement la forme d'un cylindre de révolution. Ce corps cylindrique 13 forme un contour extérieur du support 1, dont émerge axialement en parties supérieure et inférieure la tige 12, qui traverse le support, et dont émerge en partie supérieure le col 3 de la lampe. La partie en crochet 17 est réalisée par un évidement vers l'intérieur du corps cylindrique 13.The support 1 here comprises a generally cylindrical body 13. The body 13, in the illustrated case, has generally the shape of a cylinder of revolution. This cylindrical body 13 forms an outer contour of the support 1, from which emerges axially in upper and lower parts the rod 12, which passes through the support, and which emerges in the upper part the neck 3 of the lamp. The hook portion 17 is formed by a recess inwardly of the cylindrical body 13.

Les fonctions de glissière le long de la tige 12, de maintien du col de lampe, et de crochet de suspension sont ainsi assurées dans un volume réduit, limité par les contours extérieurs du cylindre 13.The slide functions along the rod 12, holding the lamp collar, and suspension hook are thus provided in a reduced volume, limited by the outer contours of the cylinder 13.

Afin de limiter l'encombrement du support 1 suivant la direction "z" perpendiculaire au mur, le diamètre de l'élément cylindrique 13 est à peine plus important que celui nécessaire pour englober la tige 12 et le col 3, placés l'un à côté de l'autre. Typiquement, le diamètre maximal du cylindre 13 peut être inférieur ou égal à 1,5 fois la somme des diamètres de la tige 12 et du col 3. La tige peut par exemple présenter un diamètre compris entre 2 et 8mm, de préférence inférieur à 6mm, par exemple de l'ordre de 4mm. Le diamètre maximal du support 1 est de préférence inférieur à 30mm. Il est de préférence compris entre 15mm et 25mm, par exemple égal à 22mm. On entend par diamètre maximal du support 1, la plus grande des deux dimensions suivantes :

  • la plus grande largeur du support 1 suivant une direction perpendiculaire au mur,
  • la plus grande largeur suivant l'horizontale du support 1, prise le long d'une droite interceptant soit l'orifice 14 faisant glissière, soit l'orifice 15 recevant le col de lampe, soit la paroi séparant les deux orifices.
In order to limit the size of the support 1 in the direction "z" perpendicular to the wall, the diameter of the cylindrical element 13 is barely larger than that necessary to encompass the rod 12 and the neck 3, placed one to next to each other. Typically, the maximum diameter of the cylinder 13 may be less than or equal to 1.5 times the sum of the diameters of the rod 12 and the neck 3. The rod may for example have a diameter of between 2 and 8 mm, preferably less than 6 mm , for example of the order of 4mm. The maximum diameter of the support 1 is preferably less than 30 mm. It is preferably between 15mm and 25mm, for example equal to 22mm. The maximum diameter of the support 1 is understood to mean the larger of the following two dimensions:
  • the largest width of the support 1 in a direction perpendicular to the wall,
  • the largest width along the horizontal of the support 1, taken along a line intercepting either the orifice 14 sliding, or the orifice 15 receiving the lamp neck, or the wall separating the two orifices.

En effet, le support peut éventuellement présenter au niveau de sa surface d'appui une largeur horizontale supérieure à ses largeurs au droit des orifices 14 et 15.Indeed, the support may optionally have at its bearing surface a horizontal width greater than its widths to the right of orifices 14 and 15.

On entend ici par « diamètre de la tige » et « diamètre du col » leurs plus petites dimensions notamment si par exemple la tige a une section rectangulaire.The term "diameter of the stem" and "diameter of the neck" is here understood to mean their smaller dimensions, especially if, for example, the stem has a rectangular section.

Afin de disposer d'une épaisseur de matière suffisante -suivant la direction perpendiculaire au mur- le crochet 17 est creusé en dessous du logement 15 réservé à l'insertion du col 3.In order to have a sufficient thickness of material - following the direction perpendicular to the wall - the hook 17 is dug below the housing 15 reserved for the insertion of the neck 3.

Selon un mode de réalisation préféré, on limite l'épaisseur de la portion entourant le col 3, et on réserve au contraire une profondeur suffisante au crochet 17 pour faciliter l'insertion de cordons de suspension de diverses épaisseurs. On se retrouve alors avec au moins une portion de l'évidement de crochet 17 dans le prolongement axial du col 3 de la lampe. Ainsi, l'objet accroché se retrouve-t-il positionné, suivant la direction perpendiculaire au mur, au plus près du col de lampe.According to a preferred embodiment, the thickness of the portion surrounding the neck 3 is limited and, on the contrary, a depth is reserved. sufficient hook 17 to facilitate the insertion of suspension strings of various thicknesses. We then find ourselves with at least a portion of the hook recess 17 in the axial extension of the neck 3 of the lamp. Thus, the hung object is positioned, in the direction perpendicular to the wall, closer to the lamp collar.

Un passage de fils électriques 16 peut être ménagé sous le logement 15 du col, le passage de fils 16 étant de section plus réduite que le logement 15. L'évidement 17 formant crochet comporte une surface 19, formant une goulotte de fond de crochet sensiblement rectiligne et horizontale, sur laquelle vient s'appuyer le cordon 9. L'évidement 17 est délimité en partie supérieure par une surface oblique 21 qui fait office de surface de guidage d'insertion du cordon 9, et fait office de surface de rétention pouvant éviter une sortie intempestive du cordon 9 hors du crochet 17.A passage of electrical wires 16 may be formed under the housing 15 of the neck, the passage of wires 16 being of smaller section than the housing 15. The recess 17 forming a hook has a surface 19, forming a substantially hook bottom trough rectilinear and horizontal, on which bears the cord 9. The recess 17 is delimited in the upper part by an oblique surface 21 which acts as a guide surface for insertion of the cord 9, and acts as a retention surface which can avoid an untimely exit of the cord 9 from the hook 17.

La partie arrière du support 1 est munie d'un méplat 20 qui peut venir en appui contre le mur 25 et contribuer à limiter la rotation du support 1 par rapport au mur 25. Le méplat 20 peut éventuellement être recouvert d'une protection de type feutrine ou mousse plane afin de limiter les risques d'endommager le mur.The rear portion of the support 1 is provided with a flat surface 20 which can abut against the wall 25 and contribute to limiting the rotation of the support 1 relative to the wall 25. The flat part 20 may optionally be covered with a type of protection felt or flat foam to limit the risk of damaging the wall.

La figure 3 représente une variante de support destiné à une tige 12 de section ronde. La figure 4 est une vue de dessus d'une variante de support 1 destiné à une tige 12 de section carrée. Les mêmes éléments sont désignés par les mêmes références.The figure 3 represents a support variant for a rod 12 of round section. The figure 4 is a top view of a support variant 1 for a rod 12 of square section. The same elements are designated by the same references.

On a mis en exergue sur la figure 3, quelques dimensions caractéristiques du support 1 qui contribuent à améliorer la stabilité en rotation par rapport à l'axe x de l'ensemble tige + support + lampe. Ainsi, la largeur selon l'axe y de la surface d'appui 20 est désignée par la lettre « 1 », la largeur totale maximale suivant la direction y du support 1 est désignée par la lettre L, la toile de matière disponible entre l'orifice 14 de glissière pour tige et le logement 15 pour col est désignée par d4, la distance de l'axe du logement pour col 15 à la surface d'appui 20 est désignée par d1, la distance minimale de l'intérieur du crochet 17 à la surface d'appui 20 -qui influe sur le moment que peut exercer le cordon d'accrochage 9 sur le support- est désignée par d2, et la distance maximale d'une portion intérieure au crochet 17 à la surface d'appui 20, est désignée par d3. Cette dernière distance d3, suivant la position du cordon ou de la boucle de suspension à l'intérieur du crochet 17, peut également jouer sur le moment exercé par l'objet suspendu pour faire tourner le support 1 par rapport à l'axe x.We highlighted the figure 3 , a few characteristic dimensions of the support 1 which contribute to improving the stability in rotation with respect to the x axis of the assembly rod + support + lamp. Thus, the width along the y-axis of the bearing surface 20 is designated by the letter "1", the maximum total width in the y direction of the support 1 is designated by the letter L, the web of material available between rod port 14 and the neck housing 15 is designated d4, the distance from the axis of the neck housing 15 to the bearing surface 20 is designated d1, the minimum distance from the inside of the hook 17 to the bearing surface 20 - which influences the The moment that can be exerted by the hooking cord 9 on the support- is designated by d2, and the maximum distance of an inner portion of the hook 17 to the bearing surface 20, is designated d3. This last distance d3, depending on the position of the cord or the suspension loop inside the hook 17, can also play on the moment exerted by the suspended object to rotate the support 1 relative to the x axis.

L'intégration des trois fonctions glissière, maintien du col et fonction crochet à l'intérieur du même corps cylindrique 13, permet de limiter certains bras de leviers dépendant de ces longueurs caractéristiques.The integration of the three slide functions, maintaining the collar and hook function inside the same cylindrical body 13, limits certain lever arms depending on these characteristic lengths.

La toile d4 peut ainsi être réduite quasiment à zéro pour peu que l'usinage de l'orifice de glissière 14 et de logement pour col 15, ne pose pas de problème. Selon un mode de réalisation préféré, le support 1 est en effet obtenu par usinage des orifices 14, 15, 16 et de l'évidement du crochet 17, dans un profilé métallique, par exemple en alliage d'aluminium.The fabric d4 can thus be reduced to almost zero if the machining of the slide hole 14 and the neck housing 15 is not a problem. According to a preferred embodiment, the support 1 is indeed obtained by machining the orifices 14, 15, 16 and the recess of the hook 17, in a metal section, for example aluminum alloy.

Le méplat 20 peut être déjà présent sur le profilé initial ou peut être usiné a posteriori.The flat 20 may already be present on the initial section or can be machined a posteriori.

De manière typique, la distance maximale d3 entre la surface d'appui 20 et une zone intérieure au crochet -qui correspond dans la plupart des cas plus ou moins à la distance maximale entre le mur et l'avant du support 1- est inférieure ou égale à la largeur maximale L du support. On limite ainsi le bras de levier entre le mur et le cordon lorsque celui-ci se trouve, au pire des cas, proche de la face avant du support 1.Typically, the maximum distance d3 between the bearing surface 20 and an interior area of the hook - which in most cases corresponds more or less to the maximum distance between the wall and the front of the support 1 - is less than or equal to equal to the maximum width L of the support. This limits the lever arm between the wall and the cord when it is, in the worst case, close to the front face of the support 1.

Afin d'assurer un appui en rotation suffisant, la largeur « l » de la face d'appui 20 suivant la direction y, est de préférence supérieure ou égale à la moitié de la distance d2.In order to ensure sufficient rotational support, the width "1" of the bearing face 20 in the direction y is preferably greater than or equal to half the distance d2.

Toujours pour limiter les effets de bras de levier, la distance d1 entre l'axe du logement 15 du col et la surface d'appui est de préférence inférieure ou égale à la largeur totale L du support.Still to limit the effects of lever arm, the distance d1 between the axis of the housing 15 of the neck and the bearing surface is preferably less than or equal to the total width L of the support.

Grâce au positionnement du crochet sous le col de la lampe, et aux faibles bras de levier, à la fois du col par rapport au mur et du crochet par rapport au mur, on améliore la stabilité du support, on limite l'endommagement au niveau des zones d'accrochage de la tige sur la cimaise, et on optimise la qualité de l'éclairage qui se trouve dans l'alignement vertical de l'objet.Thanks to the positioning of the hook under the neck of the lamp, and the weak arms of leverage, both of the collar with respect to the wall and the hook relative to the wall, it improves the stability of the support, it limits the damage in the areas of attachment of the rod on the chair rail, and optimizes the quality of the lighting which is in the vertical alignment of the object.

En outre, on optimise l'emploi de la matière du support tout en augmentant la longueur de la glissière 14, qui s'étend à la fois sur la hauteur du crochet et la hauteur du logement 15 du col. Une bonne hauteur de la glissière 14 permet d'améliorer la stabilité en rotation du support 1 par rapport à un axe horizontal.In addition, the use of the material of the support is optimized while increasing the length of the slide 14, which extends both over the height of the hook and the height of the housing 15 of the neck. A good height of the slide 14 makes it possible to improve the rotational stability of the support 1 with respect to a horizontal axis.

L'invention ne se limite pas aux exemples de réalisation décrits et peut se décliner en de nombreuses variantes.The invention is not limited to the embodiments described and can be declined in many variants.

On peut par exemple envisager de réduire la face d'appui 20 à une génératrice d'un corps cylindrique 13 notamment si la tige présente une section rectangulaire ou carrée.One can for example consider reducing the bearing surface 20 to a generatrix of a cylindrical body 13 especially if the rod has a rectangular or square section.

La section extérieure de la portion tubulaire 13 peut ne pas être cylindrique de révolution. Elle peut par exemple être polygonale, ou elliptique.The outer section of the tubular portion 13 may not be cylindrical of revolution. It can for example be polygonal, or elliptical.

De préférence, on utilise cependant une portion tubulaire 13 dont le contour extérieur, dans un plan horizontal y-z, est défini par une forme convexe, ce qui permet d'assurer un bon rapport entre la rigidité du support et le volume occupé.Preferably, however, a tubular portion 13 is used whose outer contour, in a horizontal plane y-z, is defined by a convex shape, which ensures a good ratio between the rigidity of the support and the occupied volume.

Des variantes avec un contour extérieur concave, bien que moins rigides, restent cependant dans le cadre de l'invention. Les rapports proposés précédemment pour limiter les bras de levier au niveau des valeurs 1, L, d1, d3, d4, permettent même dans ce cas de limiter de manière intéressante les bras de levier en rotation du système.Variants with a concave outer contour, although less rigid, remain within the scope of the invention. The previously proposed ratios for limiting the lever arms to the values 1, L, d1, d3, d4, even in this case make it possible to limit in an interesting manner the lever arms in rotation of the system.

La glissière 14 peut comprendre plusieurs portions distinctes mais alignées, et peut ne pas s'étendre sur toute la hauteur du support. La longueur entre les portions extrêmes de guidage reste cependant de préférence supérieure ou égale à la longueur du logement 15 du col.The slide 14 may comprise several distinct but aligned portions, and may not extend over the entire height of the support. The length between the end portions of the guide, however, preferably remains greater than or equal to the length of the housing 15 of the neck.

L'alimentation de la rampe 4 de la lampe, notamment quand cette rampe est éclairée par des LED ne nécessitant qu'une tension modérée, peut être assurée au travers de conducteurs intégrés au profilé de cimaise 11 et au travers de la tige 12.The supply of the ramp 4 of the lamp, especially when this ramp is illuminated by LEDs requiring only a voltage moderated, can be provided through conductors integrated to the profile of chair rail 11 and through the rod 12.

Un tel exemple est par exemple représenté sur les figures 6 et 7. Sur la figure 6, un support 1' est obtenu à partir d'une tôle représentée en figure 5, recouverte d'un vernis isolant 26 sur une portion -représentée en grisé- de sa surface. Cette tôle est découpée et pliée suivant les lignes pointillées de la figure 5. On obtient ainsi une pièce monobloc définissant deux cerclages 14' en partie supérieure et inférieure du support 1', ces cerclages assurant la fonction de glissière le long de la tige 12' correspondante, représentée en figure 7. Une portion 23 des cerclages, venant au contact de la tige 12', n'est pas recouverte de vernis, de manière à autoriser un contact électrique sur ces portions entre le cerclage et la tige 12'.Such an example is for example represented on the figures 6 and 7 . On the figure 6 , a support 1 'is obtained from a sheet shown in FIG. figure 5 covered with an insulating varnish 26 on a portion -represented in gray-of its surface. This sheet is cut and folded along the dotted lines of the figure 5 . This gives a monobloc piece defining two straps 14 'in the upper and lower part of the support 1', these strapping ensuring the slide function along the corresponding rod 12 ', shown in FIG. figure 7 . A portion 23 of the strapping, coming into contact with the rod 12 ', is not coated with varnish, so as to allow electrical contact on these portions between the strapping and the rod 12'.

Une portion médiane de la tôle est repliée en arcs de cercle de manière à définir un logement 15' apte à recevoir le col 3 de la lampe.A median portion of the sheet is folded into arcs so as to define a housing 15 'adapted to receive the neck 3 of the lamp.

Dans le prolongement de la zone vernie 26, en partie inférieure du support, une languette 28 de la tôle est recourbée vers le haut de manière à former un crochet d'accroche 17', à proximité immédiate de la tige 12'. Un orifice d'alimentation 29 est ménagé en partie centrale de la tôle, dans lequel est inséré un pion conducteur 30 permettant de mettre en contact électrique une face 31 du pion intérieure au logement 15', et une face 12a de la tige 12', en évitant les contacts électriques avec la masse du support 1' lui-même. La masse du support 1' est au potentiel électrique d'une seconde face 12b de la tige, isolée de la face 12a par une couche isolante 32 intégrée à la tige. La lampe peut ainsi être alimentée en courant continu par un premier contact au niveau du pion 30, et par un second contact sur les arcs de cercle du logement 15'. On peut typiquement prévoir pour chaque rampe une puissance d'alimentation électrique de 4W à 10W, par exemple de 6W, sous une tension d'alimentation de 8V à 26V, par exemple comprise entre 12V et 24V. La luminosité des LEDs peut être choisie pour obtenir une luminosité de 450 lumen par rampe, un déflecteur de la rampe permettant en outre de concentrer le flux lumineux suivant un angle préférentiel. La couleur des LEDs ou des éléments lumineux peut être choisie de préférence avec une température de couleur supérieure ou égale à 3000K.In the extension of the varnished zone 26, in the lower part of the support, a tongue 28 of the sheet is bent upwards so as to form a hook 17 ', in the immediate vicinity of the rod 12'. A supply orifice 29 is formed in the central part of the sheet, in which is inserted a conductive pin 30 for electrically contacting a face 31 of the inner pin to the housing 15 ', and a face 12a of the rod 12', avoiding electrical contacts with the mass of the support 1 'itself. The mass of the support 1 'is at the electric potential of a second face 12b of the rod, isolated from the face 12a by an insulating layer 32 integrated in the rod. The lamp can thus be supplied with direct current by a first contact at the pin 30, and by a second contact on the arcs of the housing 15 '. We can typically provide for each ramp a power supply power of 4W to 10W, for example 6W, at a supply voltage of 8V to 26V, for example between 12V and 24V. The brightness of the LEDs can be chosen to obtain a luminosity of 450 lumen per ramp, a deflector of the ramp also allowing to concentrate the luminous flux at a preferred angle. The color of the LEDs or Luminous elements can be chosen preferably with a color temperature greater than or equal to 3000K.

La figure 7 montre un profilé de cimaise 11' associé à la tige 11'. Le profilé 11' est fixé au mur par des clips circulaires de fixation 35, et présente un rail 36 muni de deux pistes électriques 34 et 35 venant au contact c de deux faces opposées d'une extrémité supérieure 37 en forme de "T" de la tige 12', de manière à amener les deux faces 12a et 12b de la tige à deux potentiels électriques différents.The figure 7 shows a profile of chair rail 11 'associated with the rod 11'. The profile 11 'is fixed to the wall by circular fixing clips 35, and has a rail 36 provided with two electrical tracks 34 and 35 coming into contact c with two opposite faces of an upper end 37 in the shape of a "T" of the rod 12 ', so as to bring the two faces 12a and 12b of the rod to two different electrical potentials.

D'autres variantes de réalisation sont bien sûr envisageables toujours en limitant le déport horizontal de la lampe et du crochet par rapport au mur, et en regroupant les trois fonctions glissière, support de lampe et crochet, de préférence dans une même pièce monobloc.Other variants of embodiment are of course still possible by limiting the horizontal offset of the lamp and the hook relative to the wall, and combining the three functions slide, lamp holder and hook, preferably in the same single piece.
