Description

La présente invention concerne les étagères utilisées notamment dans les magasins pour la présentation des produits.The present invention relates to the shelves used especially in stores for product presentation.

L'invention concerne plus spécialement les étagères dans lesquelles des tablettes en matière transparente ou translucide sont portées par des pièces de liaison déplaçables le long de montants fixes, et sont éclairées par des sources de lumière placées de façon appropriée au regard des chants postérieurs des tablettes pour illuminer leurs chants antérieurs et/ou latéraux.The invention relates more particularly to the shelves in which shelves in transparent or translucent material are carried by movable connecting pieces along fixed uprights, and are lit by light sources appropriately placed with regard to the later songs of the shelves to illuminate their front and / or side edges.

De telles étagères sont destinées à être utilisées notamment dans les magasins de parfumerie, les pharmacies, les magasins de cosmétique, pour présenter les produits mis à la disposition de la clientèle. Les produits sont posés sur la face supérieure des tablettes, et sont éventuellement éclairés par des sources de lumière placées de façon appropriée. Dans l'agencement des magasins, il est nécessaire de disposer de tablettes réglables en hauteur et modulaires. Les tablettes doivent être disposées à des hauteurs choisies, aisément modifiables.Such shelves are intended to be used especially in perfume stores, pharmacies, cosmetic stores, to present the products available to customers. The products are placed on the face upper shelves, and are possibly lit by light sources appropriately placed. In the layout stores, it is necessary to have adjustable shelves in height and modular. The shelves must be placed selected heights, easily modifiable.

On connaít déjà des étagères modulaires, telles que décrites dans le document EP 0 970 642, dans lesquelles chaque tablette est tenue selon son bord postérieur encastré dans une rainure longitudinale d'un profilé lui-même supporté par des montants. Le profilé est de forme particulière, comportant un logement intérieur contenant un tube de lumière fluorescente qui est ainsi placé face au chant postérieur de la tablette. Une telle disposition présente un premier inconvénient résultant de l'encombrement important du profilé tenant la tablette, encombrement rendu nécessaire par la résistance mécanique que doit présenter ce profilé pour tenir la tablette chargée en porte-à-faux. Un second inconvénient est un échauffement important dû à la source de lumière, qui conduit à augmenter de façon non négligeable la température d'un magasin contenant une ou plusieurs étagères de ce type. Ce document ne permet pas, non plus, un réglage continu en hauteur des tablettes, car le profilé est tenu par des crochets engagés dans des lumières discontinues des montants.We already know modular shelves, such as described in document EP 0 970 642, in which each tablet is held according to its rear edge embedded in a longitudinal groove of a profile itself supported by amounts. The profile is of particular shape, comprising a interior housing containing a fluorescent light tube which is thus placed facing the posterior edge of the tablet. Such a provision has a first drawback resulting from the large size of the profile holding the shelf, dimensions made necessary by the mechanical resistance which must present this profile to hold the loaded shelf in overhang. A second drawback is a significant overheating due to the light source, which leads to a significant increase the temperature of a store containing one or more shelves of this guy. This document also does not allow continuous adjustment in shelf height because the profile is held by hooks engaged in discontinuous lights of the uprights.

Le document DE 34 00490 A propose de disposer une source de lumière derrière une tablette en matière transparente ou translucide. La source de lumière est incorporée dans un boítier ouvert vers l'arrière et vers l'avant, constitué par l'assemblage d'un profilé de base, de deux pinces d'extrémité et de plaques supérieure et inférieure. La source de lumière est de type tube incandescent ou tube fluorescent. Une telle solution ne résout pas le problème de l'échauffement dû à la source de lumière, ni le problème de l'encombrement.Document DE 34 00490 A proposes to have a source of light behind a tablet made of transparent material or translucent. The light source is incorporated in a housing open backwards and forwards, made up of the assembly a base profile, two end clamps and plates upper and lower. The light source is of tube type incandescent or fluorescent tube. Such a solution does not solve the problem of overheating due to the light source, nor the congestion problem.

Le document JP 08 146894 décrit une paroi verticale de partition pour étagère, dans laquelle une lame de verre dressée verticalement est engagée par sa base dans un profilé contenant une diode électroluminescente. La plaque de verre comporte des rainures dans sa face principale, pour capter la lumière. Le chant extrême de la plaque est lisse et biseauté. L'illumination provenant d'une seule diode est irrégulière et faible.Document JP 08 146894 describes a vertical wall of partition for shelf, in which an upright glass slide vertically is engaged by its base in a profile containing a light emitting diode. The glass plate has grooves in its main face, to capture the light. Extreme song of the plate is smooth and beveled. Illumination from a only one diode is irregular and weak.

Le problème proposé par la présente invention est de concevoir une nouvelle structure d'étagère à tablettes en matière transparente ou translucide, dans laquelle le chant antérieur des tablettes est illuminé de façon régulière et sans dégagement sensible de chaleur, et avec un faible encombrement de la source de lumière pour éviter toute perte de surface dans la zone postérieure des tablettes.The problem proposed by the present invention is to design a new shelf structure in terms of material transparent or translucent, in which the anterior edge of shelves is illuminated regularly and without clearance sensitive to heat, and with a small footprint of the source of light to avoid any loss of surface in the posterior area tablets.

Selon un autre objet, l'invention vise également à permettre le réglage continu de hauteur des tablettes de l'étagère.According to another object, the invention also aims to allow continuous height adjustment of the shelves on the shelf.

Pour atteindre ces objets ainsi que d'autres, l'invention prévoit une étagère réglable à chants illuminés, comprenant un bâti à montants fixes qui portent, par l'intermédiaire de pièces de liaison déplaçables, des tablettes en matière transparente ou translucide, avec une ou plusieurs sources de lumière disposées en regard des chants postérieurs des tablettes, et dans laquelle :

  • les chants illuminés sont dépolis,
  • chaque tablette à chants illuminés est associée à une source de lumière constituée d'une série de diodes électroluminescentes réparties à proximité du chant postérieur de la tablette et alimentées par une source de courant électrique.
To achieve these and other objects, the invention provides an adjustable shelf with illuminated edges, comprising a frame with fixed uprights which carry, by means of movable connecting pieces, shelves in transparent or translucent material, with a or several light sources arranged opposite the rear edges of the shelves, and in which:
  • the illuminated songs are frosted,
  • each tablet with illuminated edges is associated with a light source consisting of a series of light-emitting diodes distributed near the rear edge of the tablet and powered by a source of electric current.

Les diodes électroluminescentes permettent de réduire très sensiblement l'encombrement de la source lumineuse, en augmentant simultanément son rendement pour éviter tout dégagement excessif de chaleur.Light-emitting diodes reduce very substantially the size of the light source, increasing simultaneously its performance to avoid excessive release of heat.

Selon un mode de réalisation avantageux, la source de lumière comprend :

  • une barrette de circuit imprimé à deux pistes conductrices longitudinales parallèles,
  • des diodes électroluminescentes à montage de surface dont les bornes sont soudées respectivement à l'une ou l'autre des pistes conductrices longitudinales de la barrette de circuit imprimé pour une connexion électrique parallèle des diodes électroluminescentes,
  • des moyens de tenue mécanique pour tenir la barrette de circuit imprimé en regard du chant postérieur de la tablette, avec les diodes électroluminescentes tournées vers la tablette,
  • des moyens conducteurs pour connecter chaque piste conductrice longitudinale de la barrette de circuit imprimé à l'une des bornes de la source de courant électrique.
According to an advantageous embodiment, the light source comprises:
  • a printed circuit strip with two parallel longitudinal conductive tracks,
  • light-emitting diodes with surface mounting, the terminals of which are respectively welded to one or the other of the longitudinal conductive tracks of the printed circuit strip for a parallel electrical connection of the light-emitting diodes,
  • mechanical holding means for holding the printed circuit strip facing the rear edge of the tablet, with the light-emitting diodes facing the tablet,
  • conductive means for connecting each longitudinal conductive track of the printed circuit strip to one of the terminals of the electric current source.

Cette structure permet simultanément de réduire encore le volume occupé par la source lumineuse, tout en réduisant son coût de production.This structure simultaneously makes it possible to further reduce the volume occupied by the light source, while reducing its cost of production.

Selon un mode de réalisation avantageux, les moyens de tenue mécanique pour tenir la barrette de circuit imprimé comprennent un profilé en U dont les lèvres ont un écartement adapté pour s'engager en force sur les faces supérieure et inférieure de la tablette, en recouvrement du chant postérieur de la tablette, laissant entre le chant postérieur de tablette et le fond du profilé en U un espace suffisant pour contenir la barrette de circuit imprimé et les diodes électroluminescentes qu'elle porte.According to an advantageous embodiment, the means of mechanical strength to hold the circuit board include a U-shaped profile with lips spaced apart suitable for engaging in force on the upper faces and bottom of the shelf, covering the posterior edge of the tablet, leaving between the rear edge of the tablet and the bottom of U-profile enough space to hold the bar circuit board and the light emitting diodes it door.

La barrette de circuit imprimé portant les diodes électroluminescentes peut avantageusement être simplement engagée à coulissement longitudinal entre le chant postérieur de tablette et le profilé en U.The printed circuit board carrying the diodes advantageously can be simply engaged to longitudinal sliding between the rear edge of the shelf and the U-shaped profile.

Si nécessaire, on peut prévoir des butées anti-écrasement engagées entre le fond du profilé en U et le chant postérieur de la tablette, évitant tout risque d'écrasement des diodes électroluminescentes dans l'hypothèse d'une poussée de la tablette vers l'arrière par un utilisateur mal informé. If necessary, anti-crushing stops can be provided engaged between the bottom of the U-shaped profile and the rear edge of the tablet, avoiding any risk of crushing the diodes electroluminescent in the event of a push of the tablet backwards by an ill-informed user.

Dans une réalisation pratique, favorisant le réglage en hauteur des tablettes, on peut prévoir une étagère dans laquelle les moyens conducteurs comprennent :

  • deux pistes conductrices verticales parallèles, solidaires du bâti d'étagère, orientées vers l'avant face à une zone des chants postérieurs des tablettes de l'étagère, et connectées chacune à l'une des bornes respectives de la source de courant électrique,
  • deux tiges conductrices télescopiques à ressort, dont une première extrémité est soudée à une piste conductrice longitudinale respective de la barrette de circuit imprimé, et dont la seconde extrémité vient en appui glissant sur une piste conductrice verticale respective.
In a practical embodiment, favoring the height adjustment of the shelves, a shelf can be provided in which the conductive means comprise:
  • two parallel vertical conductive tracks, integral with the shelf frame, oriented towards the front facing an area of the rear edges of the shelves of the shelf, and each connected to one of the respective terminals of the electric current source,
  • two spring-loaded telescopic conductive rods, one first end of which is welded to a respective longitudinal conductive track of the printed circuit board, and the second end of which comes to slide on a respective vertical conductive track.

De préférence, les secondes extrémités des tiges conductrices télescopiques à ressort sont arrondies en forme de boule.Preferably, the second ends of the rods telescopic spring conductors are rounded in the shape of ball.

En pratique, les pistes conductrices verticales peuvent être avantageusement fixées respectivement dans deux gorges parallèles d'un profilé à deux gorges ouvertes vers l'avant et fixé à un fond vertical du bâti de l'étagère.In practice, vertical conductive tracks can advantageously be fixed respectively in two grooves parallels of a profile with two grooves open towards the front and fixed to a vertical bottom of the shelf frame.

En pratique, les tablettes peuvent reposer sur des équerres qui sont montées coulissantes dans des glissières verticales de montants fixes et qui sont blocables en toutes positions par des vis.In practice, the shelves can rest on brackets which are slidably mounted in slides vertical uprights which are lockable in all positions by screws.

Dans le mode de réalisation illustré sur les figures, une étagère selon l'invention comprend des montants fixes tels que les montants 1 et 2 postérieurs, verticaux et parallèles, qui portent, par l'intermédiaire de pièces de liaison déplaçables telles que les équerres 3 et 4, des tablettes en matière transparente ou translucide telles que la tablette 5, orientées sensiblement horizontalement.In the embodiment illustrated in the figures, a shelf according to the invention comprises fixed uprights such as the uprights 1 and 2 posterior, vertical and parallel, which bear, by means of movable connecting parts such as the brackets 3 and 4, shelves in transparent material or translucent such as the shelf 5, oriented substantially horizontally.

Chaque tablette telle que la tablette 5 est limitée par un chant antérieur 6, un chant postérieur 7 et des chants latéraux 8 et 9.Each tablet such as tablet 5 is limited by a front edge 6, rear edge 7 and side edges 8 and 9.

Selon l'invention, on réalise une illumination du chant antérieur 6, et éventuellement des chants latéraux 8 et 9, en plaçant au regard du chant postérieur 7 une source de lumière appropriée.According to the invention, an illumination of the song is carried out anterior 6, and possibly side edges 8 and 9, in placing a light source at the rear edge 7 appropriate.

Les chants illuminés tels que le chant antérieur 6 et éventuellement les chants latéraux 8 et 9 sont dépolis, de façon à répartir l'intensité lumineuse provenant de la source de lumière placée face au chant postérieur 7.Illuminated songs such as the previous song 6 and possibly the side edges 8 and 9 are frosted, so that distribute the light intensity from the light source facing the posterior edge 7.

De préférence, les chants à illuminer, tels que le chant antérieur 6 et les chants latéraux 8 et 9, sont perpendiculaires au plan général de l'étagère ou plan des faces principales, de façon à maximiser l'illumination.Preferably, the songs to be illuminated, such as the song anterior 6 and the side edges 8 and 9 are perpendicular to the general plan of the shelf or plan of the main faces, so that maximize illumination.

Pour la même raison, il est préférable que les faces principales de l'étagère soient lisses, de sorte que les rayons lumineux soient concentrés sur les chants illuminés.For the same reason, it is preferable that the faces main shelves are smooth so that the shelves are concentrated on the illuminated songs.

La source de lumière placée face au chant postérieur 7 est alimentée par des moyens conducteurs comprenant deux pistes conductrices verticales 10 et 11 parallèles, orientées vers l'avant face à une zone des chants postérieurs 7 des tablettes 5 de l'étagère, et connectées chacune à l'une des bornes respectives 12 et 13 d'une source de courant électrique 14.The light source placed facing the posterior edge 7 is powered by conductive means comprising two tracks vertical conductors 10 and 11 parallel, facing forward facing an area of the rear songs 7 of the shelves 5 of the shelf, and each connected to one of the respective terminals 12 and 13 from an electric current source 14.

Dans le mode de réalisation illustré sur les figures 1 à 3, la liaison entre les tablettes 5 et les montants fixes 1 et 2 est assurée par les équerres 3 et 4 qui sont déplaçables de façon continue le long des montants fixes 1 et 2. Comme on le voit sur la figure 2, l'équerre 3 comporte, sur sa face latérale destinée à venir en appui contre le montant fixe 1, deux plots de guidage 15 et 16 alignés verticalement, et une lumière de serrage 17 en forme de trou de serrure inversé aligné avec les plots de guidage 15 et 16.In the embodiment illustrated in Figures 1 to 3, the connection between the shelves 5 and the fixed uprights 1 and 2 is provided by the brackets 3 and 4 which are movable so continues along the fixed uprights 1 and 2. As seen on the Figure 2, the bracket 3 has, on its side face intended for come into abutment against the fixed upright 1, two guide pads 15 and 16 aligned vertically, and a clamping light 17 shaped of an inverted keyhole aligned with the guide studs 15 and 16.

Les montants fixes 1 et 2, et plus particulièrement le montant fixe 1 tel qu'illustré sur la figure 3, ont une structure profilée à section transversale généralement carrée et comportant, sur chaque face, une rainure longitudinale telles que les rainures 18, 19, 20 et 21 à orifice plus étroit que la cavité intérieure des rainures. Par exemple, la cavité intérieure des rainures est de forme rectangulaire, plus large que l'orifice correspondant.The fixed amounts 1 and 2, and more particularly the fixed upright 1 as illustrated in FIG. 3, have a structure profiled section generally square and comprising, on each side, a longitudinal groove such as the grooves 18, 19, 20 and 21 with a hole narrower than the interior cavity of the grooves. For example, the interior cavity of the grooves is rectangular shape, wider than the corresponding opening.

En position assemblée, comme illustré sur la figure 3, une vis 22 est engagée à travers la lumière de serrage 17 de l'équerre 3, avec sa tête 23 portant sur la face interne de l'équerre 3, la tige de vis 22 traversant également l'orifice de la rainure 18 correspondante du montant fixe 1. Un écrou 24 est logé dans la cavité de rainure 18, et est vissé sur l'extrémité de la tige de la vis 22 en étant bloqué en rotation dans la rainure 18 sans pouvoir sortir par l'orifice. Par rotation de la tête 23 de la vis 22, l'extrémité de tige de la vis 22 vient porter dans le fond de la rainure et bloque l'équerre 3 en coulissement le long du montant fixe 1, tandis que les plots de guidage 15 et 16 engagés dans l'orifice de la rainure 18 interdisent tout basculement de l'équerre 3.In the assembled position, as illustrated in FIG. 3, a screw 22 is engaged through the clamping light 17 of the bracket 3, with its head 23 bearing on the internal face of the bracket 3, the screw rod 22 also passing through the hole in the groove 18 corresponding to the fixed amount 1. A nut 24 is housed in the groove cavity 18, and is screwed onto the end of the rod of the screw 22 while being locked in rotation in groove 18 without power exit through the opening. By rotation of the head 23 of the screw 22, the rod end of the screw 22 comes to bear in the bottom of the groove and blocks the square 3 sliding along the upright fixed 1, while the guide pads 15 and 16 engaged in the hole in the groove 18 prohibits any tilting of square 3.

Comme illustré sur la figure 1, en plaçant deux équerres 3 et 4 à même hauteur, on peut poser la tablette 5 sur les chants supérieurs des deux équerres 3 et 4.As illustrated in Figure 1, by placing two brackets 3 and 4 at the same height, we can put the shelf 5 on the edges upper of the two brackets 3 and 4.

La tablette 5 est associée à une source de lumière 25 constituée d'une série de plusieurs diodes électroluminescentes réparties à proximité du chant postérieur 7 de la tablette 5 et alimentées par la source de courant électrique 14. On peut par exemple placer une diode électroluminescente tous les deux ou trois centimètres, d'autres écartements étant toutefois possibles en fonction de l'intensité d'éclairement désirée.The tablet 5 is associated with a light source 25 consisting of a series of several light-emitting diodes distributed near the rear edge 7 of the shelf 5 and powered by the electric current source 14. It is possible by example place a light emitting diode every two or three centimeters, other spacings being however possible in depending on the desired light intensity.

En considérant plus spécialement les figures 4 à 6, on voit que la source de lumière 25 comprend une barrette de circuit imprimé 26 ayant un substrat 27 et deux pistes conductrices longitudinales 28 et 29 parallèles. Des diodes électroluminescentes telles que les diodes 30, 31 et 32, de type à montage de surface, sont connectées entre les deux pistes conductrices longitudinales 28 et 29 parallèles. Leurs bornes telles que les bornes 33 et 34 de la diode électroluminescente 30 sont soudées respectivement à l'une ou l'autre des pistes conductrices longitudinales 28 et 29, de sorte que les diodes électroluminescentes 30-32 sont connectées électriquement en parallèle.Looking more specifically at Figures 4 to 6, we sees that the light source 25 includes a circuit strip printed 26 having a substrate 27 and two conductive tracks longitudinal 28 and 29 parallel. Light emitting diodes such as diodes 30, 31 and 32, of the surface mount type, are connected between the two longitudinal conductive tracks 28 and 29 parallels. Their terminals such as terminals 33 and 34 of the light emitting diode 30 are soldered to one respectively either of the longitudinal conductive tracks 28 and 29, so that the light emitting diodes 30-32 are connected electrically in parallel.

Les diodes électroluminescentes constituent une source de lumière à haut rendement d'émission lumineuse, et de faibles dimensions. Les diodes électroluminescentes à montage de surface ont une forme générale de bâtonnet à deux fils de connexion, directement implantable sur un circuit imprimé. On peut par exemple utiliser des diodes électroluminescentes de référence KA-3022PWC-4.55F distribués par la société KINGBRIGHT. Ces diodes émettent une lumière blanche. D'autres diodes électroluminescentes peuvent toutefois être utilisées, en fonction de la couleur et de la puissance lumineuse à obtenir.Light emitting diodes are a source of light with high light emission efficiency, and low dimensions. Surface mount light emitting diodes have the general shape of a stick with two connecting wires, directly implantable on a printed circuit. We can for example use reference light-emitting diodes KA-3022PWC-4.55F distributed by the company KINGBRIGHT. These diodes emit a White light. Other light emitting diodes may however be used, depending on the color and light output to be obtained.

Des moyens de tenue mécanique permettent de tenir la barrette de circuit imprimé 26 en regard du chant postérieur 7 de la tablette 5, avec les diodes électroluminescentes 30-32 tournées vers la tablette 5. Dans la réalisation illustrée sur les figures, les moyens de tenue mécanique comprennent un profilé en U 35 dont les lèvres 36 et 37 ont un écartement adapté pour s'engager en force sur les faces supérieure 54 et inférieure 55 de la tablette 5, en recouvrement du chant postérieur 7 de la tablette 5. Le profilé en U 35 laisse entre le chant postérieur 7 de la tablette 5 et le fond 38 du profilé en U 35 un espace 39 suffisant pour contenir la barrette de circuit imprimé 26 et les diodes électroluminescentes 30-32 qu'elle porte. De préférence, le profilé en U 35 est réalisé en un matériau électriquement isolant, par exemple en matière plastique extrudée.Mechanical holding means make it possible to hold the printed circuit board 26 opposite the rear edge 7 of the tablet 5, with the light-emitting diodes 30-32 turned towards the tablet 5. In the embodiment illustrated in the figures, the mechanical holding means comprise a U-shaped section 35 of which the lips 36 and 37 have a spacing adapted to engage in force on the upper 54 and lower 55 faces of the tablet 5, overlapping the rear edge 7 of the tablet 5. The U-shaped 35 leaves between the rear edge 7 of the shelf 5 and the bottom 38 of the U-shaped profile 35 a space 39 sufficient for contain the printed circuit board 26 and the diodes 30-32 light emitting lights that she wears. Preferably, the profile in U 35 is made of an electrically insulating material, by example in extruded plastic.

Par exemple, la barrette de circuit imprimé 26 portant les diodes électroluminescentes 30-32 est engagée à coulissement longitudinal, comme illustré par la flèche 40 de la figure 6, entre le chant postérieur 7 de la tablette et le profilé en U 35. Eventuellement, des butées anti-écrasement, non illustrées sur les figures, sont engagées entre le fond 38 du profilé en U 35 et le chant postérieur 7 de la tablette 5.For example, the printed circuit board 26 carrying the light emitting diodes 30-32 is slidably engaged longitudinal, as illustrated by arrow 40 in FIG. 6, between the rear edge 7 of the shelf and the U-shaped profile 35. Possibly anti-crushing stops, not illustrated on the figures, are engaged between the bottom 38 of the U-shaped profile 35 and the posterior edge 7 of the tablet 5.

Des moyens conducteurs permettent de connecter chaque piste conductrice longitudinale 28 ou 29 de la barrette de circuit imprimé 26 à l'une des bornes 12 ou 13 de la source de courant électrique 14.Conductive means make it possible to connect each longitudinal conductive track 28 or 29 of the circuit strip printed 26 at one of terminals 12 or 13 of the current source electric 14.

Dans la réalisation illustrée plus spécialement sur les figures 1, 4 et 5, les moyens conducteurs comprennent les deux pistes conductrices verticales parallèles 10 et 11 précédemment mentionnées, et deux tiges conductrices télescopiques à ressort 41 et 42. En se référant à la figure 4, on voit les deux tiges conductrices télescopiques à ressort 41 et 42, orientées selon une direction antéropostérieure horizontale, et s'étendant entre les pistes conductrices verticales 10 et 11 et la barrette de circuit imprimé 26. Une première extrémité respective 43 ou 44 de chaque tige conductrice télescopique à ressort 41 ou 42 est soudée à une piste conductrice longitudinale respective 29 ou 28 de la barrette de circuit imprimé 26, et sa seconde extrémité respective 45 ou 46 vient en appui glissant sur une piste conductrice verticale respective 10 ou 11. Comme on le voit sur la figure 4, les secondes extrémités 45 et 46 des tiges conductrices télescopiques à ressort 41 et 42 sont arrondies en forme de boule. Dans chacune des tiges conductrices télescopiques à ressort 41 ou 42, un ressort intermédiaire 47 ou 48 de compression repousse élastiquement la seconde extrémité 45 ou 46 contre la piste conductrice verticale respective 10 ou 11, assurant un contact électrique permanent.In the embodiment illustrated more particularly on the Figures 1, 4 and 5, the conductive means comprise both parallel vertical conductor tracks 10 and 11 previously mentioned, and two telescopic spring conductive rods 41 and 42. Referring to FIG. 4, we see the two rods telescopic spring conductors 41 and 42, oriented in a horizontal anteroposterior direction, and extending between the vertical conductor tracks 10 and 11 and the circuit strip printed 26. A respective first end 43 or 44 of each telescopic conductive rod with spring 41 or 42 is welded to a respective longitudinal conductive track 29 or 28 of the bar of printed circuit 26, and its respective second end 45 or 46 comes to sliding support on a vertical conductive track respectively 10 or 11. As seen in Figure 4, the seconds ends 45 and 46 of the telescopic spring-loaded conductive rods 41 and 42 are rounded in the shape of a ball. In each of the stems telescopic conductors with spring 41 or 42, one spring compression intermediate 47 or 48 elastically repels the second end 45 or 46 against the vertical conductive track respectively 10 or 11, ensuring permanent electrical contact.

Les pistes conductrices verticales 10 et 11 sont fixées respectivement dans deux gorges parallèles 49 et 50 d'un profilé 51 à deux gorges ouvertes vers l'avant et fixé à un fond vertical du bâti de l'étagère. Les pistes conductrices verticales 10 et 11 sont par exemple collées dans le fond des gorges parallèles 49 et 50 respectives.The vertical conductive tracks 10 and 11 are fixed respectively in two parallel grooves 49 and 50 of a profile 51 with two grooves open towards the front and fixed to a vertical bottom of the shelf frame. The vertical conductive tracks 10 and 11 are for example glued in the bottom of the parallel grooves 49 and 50 respectively.

La source de courant électrique 14 peut avantageusement être une alimentation à découpage, délivrant à partir de l'alimentation du secteur 52, une tension électrique de 5 volts environ. Les diodes électroluminescentes 30-32 peuvent avoir une tension nominale de fonctionnement de 3,5 volts environ. Une résistance électrique 53 peut avantageusement être connectée en série entre l'une au moins des pistes conductrices longitudinales 28 ou 29 de la barrette de circuit imprimé 26 et les moyens conducteurs de connexion à la source de courant électrique 14. Par exemple, comme illustré sur les figures 4 et 5, la résistance électrique 53 est connectée entre deux tronçons successifs isolés de la piste conductrice longitudinale 28, en amont des diodes électroluminescentes 30-32.The electric current source 14 can advantageously be a switching power supply, delivering from the mains supply 52, an electrical voltage of 5 volts about. Light emitting diodes 30-32 may have a nominal operating voltage of approximately 3.5 volts. A electrical resistance 53 can advantageously be connected in series between at least one of the longitudinal conductive tracks 28 or 29 of the printed circuit board 26 and the means conductors for connection to the electric current source 14. Par example, as illustrated in figures 4 and 5, the resistance electric 53 is connected between two successive isolated sections of the longitudinal conductive track 28, upstream of the diodes light emitting 30-32.

En utilisant, sur une même barrette de circuit imprimé 26, une dizaine de diodes électroluminescentes telles que les diodes 30-32, avec chaque diode ayant une consommation nominale de 20 milliampères environ, on peut utiliser une résistance électrique 53 de 7 à 8 ohm et d'une puissance d'1/2 watt.By using, on the same printed circuit board 26, a dozen light-emitting diodes such as diodes 30-32, with each diode having a nominal consumption of About 20 milliamps, you can use an electrical resistance 53 from 7 to 8 ohm and a power of 1/2 watt.

Les diodes électroluminescentes 30-32 constituent des sources ponctuelles de lumière, et les chants dépolis tels que le chant antérieur 6 assurent une répartition uniforme de l'illumination visible depuis l'avant de la tablette.Light emitting diodes 30-32 are point sources of light, and frosted edges such as the front edge 6 ensure a uniform distribution of the illumination visible from the front of the tablet.
