The electricity distribution line, usable especially in an interior installation for low voltage light bulb supply, comprises a rail (10) formed by a flexible insulating core coated with strips of conducting metal, which are sufficiently thin to be able to be rolled up. The lateral edges of the rail are embedded in borders (12) of the core. The rail is held by supports each comprising two shells made of electrically insulating material permitting them to be applied against one another by clamping the borders and may be in sections connected by sleeve tubes. <IMAGE>

Description

La présente invention concerne les lignes de distribution d'électricité à basse tension et elle trouve une application particulière importante, bien que non exclusive, dans les installations intérieures de distribution d'électricité à basse tension à des lampes.The present invention relates to low voltage electricity distribution lines and it finds an important, although not exclusive, application in indoor installations for distributing low voltage electricity to lamps.

Il est souvent utile de prévoir une installation permettant de modifier la position de lampes d'éclairage. Ce cas est notamment celui des vitrines et des magasins. L'utilisation de rails de supportage des lampes ne résoud que très imparfaitement ce problème. Les rails utilisés, étant rigides, ne peuvent être transportés que sous forme de tronçons relativement courts, impliquant des raccordements nombreux, mais les tronçons restent néanmoins encombrants. Il est impossible ou difficile de cintrer ces rails sur place pour leur faire suivre un tracé sinueux. Les fonctions de supportage des récepteurs d'électricité et d'alimentation de ces récepteurs sont généralement dissociées.It is often useful to provide an installation for changing the position of lighting lamps. This is particularly the case for shop windows and stores. The use of lamp support rails solves this problem only very imperfectly. The rails used, being rigid, can only be transported in the form of relatively short sections, involving numerous connections, but the sections nevertheless remain bulky. It is impossible or difficult to bend these rails in place to make them follow a winding path. The functions of supporting the electricity receivers and supplying these receivers are generally dissociated.

On connaît (DE-U-8 808 131) une ligne conforme au préambule de la revendication 1. L'âme est constituée par une bande flexible ou rigide, à laquelle les deux bandes métalliques sont fixées par un procédé non décrit.We know (DE-U-8 808 131) a line according to the preamble of claim 1. The core consists of a flexible or rigid strip, to which the two metal strips are fixed by a method not described.

La présente invention vise à fournir une ligne de distribution d'électricité répondant mieux que celles antérieurement connues aux exigences de la pratique et des accessoires spécialement adaptés à une telle ligne.The present invention aims to provide an electricity distribution line that better meets those previously known to the requirements of practice and accessories specially adapted to such a line.

Dans ce but l'invention propose notamment une ligne de distribution d'électricité à des récepteurs, conforme à la revendication 1.To this end, the invention proposes in particular a line for distributing electricity to receivers, in accordance with claim 1.

Le support peut avoir un boîtier constitué de deux coquilles en matériau électriquement isolant munies de moyens permettant de les appliquer l'une contre l'autre en serrant les bordures et/ou le rail.The support may have a housing made up of two shells of electrically insulating material provided with means making it possible to apply them one against the other by tightening the edges and / or the rail.

Le rail en lui-même constitue un composant stockable en tronçons de quelques mètres de long sous forme de bobine de quelques dizaine de centimètres de diamètre ; ce rail peut suivre un trajet sinueux et/ou vrillé et suivre un trajet en hélice ; il peut être supporté par des parois d'orientation quelconque, variant le long de la ligne ; il revient à l'état rectiligne lorsqu'il est libéré.The rail itself constitutes a component that can be stored in sections a few meters long in the form of a coil of a few tens of centimeters in diameter; this rail can follow a winding and / or twisted path and follow a helical path; it can be supported by walls of any orientation, varying along the line; it returns to the rectilinear state when it is released.

L'invention propose également un adaptateur de récepteur électrique pour une ligne du type ci-dessus défini, conforme à la revendication 7.The invention also provides an electrical receiver adapter for a line of the type defined above, according to claim 7.

D'autres caractéristiques encore apparaissent dans les revendications.Still other characteristics appear in the claims.

L'invention sera mieux comprise à la lecture de la description qui suit d'un mode particulier de réalisation, donné à titre d'exemple non limitatif. La description se réfère aux dessins qui l'accompagnent, dans lesquels :

  • la figure 8, similaire à une fraction de la figure 6, montre une variante.
The invention will be better understood on reading the following description of a particular embodiment, given by way of non-limiting example. The description refers to the accompanying drawings, in which:
  • Figure 1 is a block diagram showing a line fragment according to the invention and a connecting sleeve between two sections, in perspective;
  • Figure 2 is an elevational view showing a lamp adapter according to a particular embodiment of the invention;

La figure 1 montre uniquement un fragment de ligne suivant l'invention, situé en dehors des zones qui reçoivent des supports ou des récepteurs. Ce fragment comporte en revanche un raccordement entre deux tronçons successifs.Figure 1 shows only a line fragment according to the invention, located outside the areas which receive supports or receivers. However, this fragment includes a connection between two successive sections.

Chaque tronçon de ligne comporte un rail plat 10 de structure composite, dont les tranches latérales sont embottées dans des bordures 12. Le rail comprend une âme isolante 14 portant sur chaque face une bande conductrice 16, dont les tranches et une fraction de la surface sont recouvertes par les bordures 12 de l'âme. Les matériaux constitutifs du rail et l'épaisseur du rail sont choisis de façon que l'ensemble soit stockable sous forme d'un rouleau de quelques décimètres de diamètre. Dans la pratique, l'âme pourra être en chlorure de polyvinyle souple ayant une épaisseur de l'ordre du millimètre, suffisante pour assurer l'isolement en basse tension. Les bandes conductrices peuvent être en bronze au béryllium, revêtu d'une pellicule mince de protection (en nickel par exemple) ou en chrysocale, ayant chacune une épaisseur comprise entre 0,2 et 0,8 mm, suivant la conductivité requise.Each line section comprises a flat rail 10 of composite structure, the lateral edges of which are embedded in edges 12. The rail comprises an insulating core 14 carrying on each face a conductive strip 16, the edges and a fraction of the surface of which are covered by the edges 12 of the core. The constituent materials of the rail and the thickness of the rail are chosen so that the assembly can be stored in the form of a roll of a few decimeters in diameter. In practice, the core may be made of flexible polyvinyl chloride having a thickness of the order of a millimeter, sufficient to ensure isolation at low voltage. The conductive strips can be made of beryllium bronze, coated with a thin protective film (nickel for example) or chrysocale, each having a thickness of between 0.2 and 0.8 mm, depending on the conductivity required.

Les bordures, dont la section droite est en forme de U (arrondi sur la figure 1, ou à angles droits comme sur la figure 3), peuvent être emboîtées sur une bande conductrice très facilement par simple déformation élastique d'un des bras de la section en U en faisant glisser un outil le long d'une lame, après que la bande ait été insérée dans l'autre bordure.The edges, whose cross section is U- shaped (rounded in Figure 1, or at right angles as in Figure 3), can be fitted onto a conductive strip very easily by simple elastic deformation of one of the arms of the U- section by sliding a tool along a blade, after the strip has been inserted into the other border.

A titre d'exemple, on peut indiquer qu'un rail de 35 mm de large et de 2 mm d'épaisseur, enroulable sous un diamètre de 50 cm, a donné des résultats satisfaisants.By way of example, it can be indicated that a rail 35 mm wide and 2 mm thick, which can be rolled up to a diameter of 50 cm, has given satisfactory results.

Comme le montre la figure 1, une telle ligne est aisément déformable pour lui faire suivre un tracé sinueux.As shown in Figure 1, such a line is easily deformable to make it follow a sinuous path.

Le raccordement entre deux tronçons successifs peut être réalisé par divers moyens, notamment à l'aide de manchons 18 du genre montré en figure 1. Ce manchon 18 est constitué de deux coquilles 20 délimitées par un fond convexe et deux flancs parallèles découpés de façon que leurs bords ne s'appuient l'un sur l'autre que si les flancs compriment les bordures 12. Les coquilles 20 peuvent être aisément réalisées par moulage de matériau isolant synthétique. Les coquilles peuvent être maintenues appliquées l'une contre l'autre par des moyens quelconques, notamment par encliquetage et/ou à l'aide de pinces 22 ayant la même constitution que celles équipant les adaptateurs de récepteur qui seront décrits plus loin. La continuité électrique est établie entre deux tronçons successifs par exemple à l'aide de plaquettes élastiques en matériau conducteur 24, ayant par exemple une forme d'arceau prenant appui sur les coquilles et dont le fond relie les tronçons : un tel montage permet sans difficulté de faire des courants de l'ordre de 20 A.The connection between two successive sections can be achieved by various means, in particular using sleeves 18 of the kind shown in FIG. 1. This sleeve 18 consists of two shells 20 delimited by a convex bottom and two parallel flanks cut so that their edges only lean against each other if the sides compress the edges 12. The shells 20 can be easily produced by molding synthetic insulating material. The shells can be kept applied one against the other by any means, in particular by snap-fastening and / or using clamps 22 having the same constitution as those fitted to the receiver adapters which will be described later. Electrical continuity is established between two successive sections, for example using elastic plates of conductive material 24, for example having a hoop shape resting on the shells and whose bottom connects the sections: such an assembly allows without difficulty to make currents of the order of 20 A.

L'adaptateur 24 montré à titre d'exemple sur les figures 2 et 3 est destiné à recevoir une lampe dichroïque basse tension 26 et son réflecteur 28. Mais il serait possible de constituer des adaptateurs similaires destinés à d'autres récepteurs.The adapter 24 shown by way of example in FIGS. 2 and 3 is intended to receive a low-voltage dichroic lamp 26 and its reflector 28. However, it would be possible to form similar adapters intended for other receivers.

L'adaptateur 24 comporte un bottier formé de deux coquilles 30 identiques, mais montées tête-bêche, en matériau électriquement isolant. Le fond de chaque coquille présente une face externe convexe et une face interne telle que les coquilles puissent enserrer les bordures 12 en les déformant élastiquement, comme cela apparaît sur la figure 3. De plus, dans le mode de réalisation représenté, chaque coquille comporte un cliquet élastique 32 prévu pour venir s'accrocher sur une saillie 3 de l'autre coquille lorsque les deux coquilles sont suffisamment rapprochées pour comprimer les bordures et être immobilisées par frottement le long du rail. Le verrouillage est complété par des pinces 36 qui peuvent être identiques aux pinces 22 d'assemblage des manchons 18. Ces pinces peuvent être constituées par une pièce de feuillard élastique mise en forme, dont les parties terminales ont une forme telle qu'elles s'accrochent sur les coquilles.The adapter 24 comprises a case formed by two identical shells 30, but mounted head to tail, of electrically insulating material. The bottom of each shell has a convex outer face and an inner face such that the shells can grip the edges 12 by deforming them elastically, as appears in FIG. 3. In addition, in the embodiment shown, each shell has a elastic pawl 32 provided to hang on a projection 3 of the other shell when the two shells are close enough to compress the edges and be immobilized by friction along the rail. The locking is completed by pliers 36 which can be identical to the pliers 22 for assembling the sleeves 18. These pliers can consist of a shaped elastic strip piece, the end parts of which have a shape such that they hang on the shells.

D'autres modes de fixation sont possibles et en particulier les deux coquilles peuvent comporter des zones formant charnière d'un côté du rail.Other methods of attachment are possible and in particular the two shells can include zones forming a hinge on one side of the rail.

La paroi interne de chaque coquille présente un bossage 38 dans lequel est encastrée une lame élastique 40 d'appui sur l'une des bandes 16. Cette lame constitue un élément de prélèvement de courant. Elle est prévue pour être reliée à un fil souple 42 d'alimentation du récepteur. Une solution simple de jonction du fil 42 consiste à le munir d'une cosse terminale 44 embottable sur une patte 42 appartenant à une pièce en tôle découpée comprenant également la lame 40.The internal wall of each shell has a boss 38 in which is embedded an elastic blade 40 for bearing on one of the strips 16. This blade constitutes a current drawing element. It is intended to be connected to a flexible wire 42 supplying the receiver. A simple solution for joining the wire 42 consists in providing it with a terminal lug 44 which can be fitted onto a tab 42 belonging to a cut sheet metal part also comprising the blade 40.

Chacune des coquilles 30 est percée en son centre d'un trou de réception d'une tige 46 de supportage de la douille 47 de lampe. Dans le mode de réalisation illustré, les tiges 46 sont creuses et servent également de passage pour les fils 42 d'alimentation.Each of the shells 30 is pierced in its center with a hole for receiving a rod 46 for supporting the lamp socket 47. In the illustrated embodiment, the rods 46 are hollow and also serve as a passage for the supply wires 42.

Pour que la liaison entre le boîtier et les tiges permette une orientation autour d'un axe orthogonal au rail, les tiges sont montées rotatives dans les trous alignés et fixées par des moyens déserrables. Dans le cas montré en figure 3, ces moyens comprennent un écrou 48 vissé sur une partie terminale filetée de la tige correspondante.So that the connection between the housing and the rods allows orientation around an axis orthogonal to the rail, the rods are rotatably mounted in the aligned holes and fixed by desereable means. In the case shown in Figure 3, these means comprise a nut 48 screwed onto a threaded end portion of the corresponding rod.

Chaque tige 46 présente deux coudes de façon que leurs extrémités opposées à celles fixées au boîtier soient également alignées et offrent un second axe d'articulation, orthogonal à l'axe d'articulation sur le bottier. Ces deux parties terminales sont montées, par des moyens permettant une rotation, sur un étrier 50 portant la douille 47 et le réflecteur 48 : il est inutile de décrire ici le montage de l'étrier sur les tiges 46, puisqu'il peut être similaire à celui déjà décrit et le montage de l'étrier sur la douille, puiqu'il peut être classique.Each rod 46 has two elbows so that their ends opposite those fixed to the housing are also aligned and offer a second axis of articulation, orthogonal to the axis of articulation on the case. These two end parts are mounted, by means allowing rotation, on a stirrup 50 carrying the socket 47 and the reflector 48: it is unnecessary to describe here the mounting of the stirrup on the rods 46, since it can be similar to that already described and the mounting of the stirrup on the socket, since it can be conventional.

Le support 18 montré schématiquement en figure 5 est prévu lui aussi pour permettre de donner au rail 10 une orientation quelconque par rapport à une plaque de fixation 52, du moins dans une plage de débattement importante. Pour cela le support 18 peut comporter deux coquilles identiques ou similaires aux coquilles 30 d'un adaptateur, mais démunies de lames élastiques de contact et de trous de passage de tiges 46. A l'une des coquilles est fixée, par moulage ou par report à l'aide de vis, une chape 54 reliée à une tige 56 par des moyens permettant à la tige de tourner autour d'un axe parallèle à l'axe longitudinal du rail 10. La tige5 6 est elle-même montée sur la plaque 52 par des moyens permettant d'orienter la tige autour de son axe 54. Ces derniers moyens peuvent être constitués par un écrou 58 vissé sur une partie terminale filetée de la tige qui s'appuie sur la plaque 52 par un épaulement.The support 18 shown diagrammatically in FIG. 5 is also provided to allow the rail 10 to be given a any orientation relative to a fixing plate 52, at least in a large range of travel. For this, the support 18 may comprise two shells identical or similar to the shells 30 of an adapter, but devoid of elastic contact blades and rod passage holes 46. To one of the shells is fixed, by molding or by transfer using screws, a yoke 54 connected to a rod 56 by means allowing the rod to rotate about an axis parallel to the longitudinal axis of the rail 10. The rod5 6 is itself mounted on the plate 52 by means making it possible to orient the rod around its axis 54. These latter means can be constituted by a nut 58 screwed onto a threaded end portion of the rod which rests on the plate 52 by a shoulder.

Les moyens d'amenée de courant à la ligne ne sont pas représentés : ils peuvent avoir une constitution similaire à celle des manchons de raccordement 18 et être situés en un point quelconque de la ligne. En particulier ils peuvent être constitués de deux coquilles en matériau isolant, de moyens permettant de les rapprocher en enserrant des bordures et, sur chaque coquille, d'une lame large en matériau conducteur encastrée dans la coquille et prenant appui sur le rail, relié à un conducteur extérieur d'amenée.The means for supplying current to the line are not shown: they may have a constitution similar to that of the connection sleeves 18 and be located at any point on the line. In particular, they may consist of two shells of insulating material, of means enabling them to be brought together by enclosing the edges and, on each shell, of a wide strip of conductive material embedded in the shell and bearing on the rail, connected to an external supply conductor.

L'invention est susceptible de nombreuses variantes de réalisation. Par exemple les supports de ligne peuvent avoir la constitution montrée schématiquement en figures 6 et 7. Le support ou patère montré en figure 6 comporte une plaque d'accrochage 60 munie de moyens non représentés de fixation sur une paroi (mur ou cloison). A cette plaque est fixé, par exemple par soudage, un plat plié 62 dont la partie terminale fait un angle de 45°, avec l'axe de la plaque. Les éléments d'accrochage du rail sont constitués par deux pattes 64,66, en feuillard découpé et plié dont les partie terminales viennent serrer les bordures 12 et retenir le rail. Les pattes 64,66 sont solidarisées du plat 62 par une vis 68 qui s'engage dans un trou taraudé de la patte 66. Aussi il est possible d'orienter le rail autour de l'axe de la vis et de la relier soit au plafond, soit à une cloison. Les rebords terminaux 70 des pattes ont une longueur telle qu'elles ne débordent pas des bordures 12 qu'ils enserrent.The invention is susceptible of numerous variant embodiments. For example, the line supports can have the constitution shown diagrammatically in FIGS. 6 and 7. The support or coat hook shown in FIG. 6 comprises a hooking plate 60 provided with means (not shown) for fixing on a wall (wall or partition). To this plate is fixed, for example by welding, a folded plate 62 whose end part makes an angle of 45 °, with the axis of the plate. The rail hooking elements consist of two legs 64, 66, made of cut and folded strip, the end portions of which tighten the edges 12 and retain the rail. The legs 64, 66 are secured to the plate 62 by a screw 68 which engages in a tapped hole in the leg 66. Also it is possible to orient the rail around the axis of the screw and to connect it either to the ceiling, or to a partition. The end flanges 70 of the legs have a length such that they do not project beyond the edges 12 which they enclose.

Une contre-plaque 72 peut être placée sur la plaque 60 pour masquer les vis de fixation engagées dans des lumières en arc de cercle de la plaque et maintenue par des aimants 74 placés de part et d'autre de la base du plat 62.A counter-plate 72 can be placed on the plate 60 to hide the fixing screws engaged in the lights in an arc of a circle of the plate and held by magnets 74 placed on either side of the base of the dish 62.

Dans certains cas, on souhaite écarter les supports à un point tel que le rail risque de se vriller entre les supports, surtout en courbe, on souhaite disposer d'une capacité de transport d'électricité excédant celle d'un rail. Dans ce cas, il est possible de monter deux rails 10 (ou même davantage) en parallèle, comme le montre la figure 8. Les deux rails sont maintenus chacun par deux pinces de chaque support 76, par l'élasticité des pinces ou grâce à des moyens de pression réglables non représentés. On double ainsi la capacité de transport, on augmente considérablement le moment d'inertie en torsion et on fixe le rayon de cintrage.In certain cases, it is desired to separate the supports to such a point that the rail risks twisting between the supports, especially in a curve, it is desired to have an electricity transport capacity exceeding that of a rail. In this case, it is possible to mount two rails 10 (or even more) in parallel, as shown in FIG. 8. The two rails are each held by two clips from each support 76, by the elasticity of the clips or by means of adjustable pressure means not shown. This doubles the transport capacity, considerably increases the moment of inertia in torsion and fixes the bending radius.
