Le dispositif illustré comprend une lampe ou spot 1 suspendue par une tige verticale 2 à un organe de raccordement 3 fixé sur un support allongé ou rail 4. Le support 4 comprend une tige profilée rigide horizontale 5 en forme de cylindre de révolution s'étendant entre deux organes de liaison 6 et 7 disposés respectivement aux deux extrémités du support. Deux câbles conducteurs flexibles 8 sont tendus entre les organes 6 et 7 de façon à s'étendre parallèlement à l'axe de révolution 9 de la tige profilée 5, dans le plan horizontal de cet axe et symétriquement l'un de l'autre par rapport à celui-ci. Sur chacun des organes de liaison 6 et 7 fait saillie, à l'opposé de l'autre organe de liaison, un élément d'accrochage 10, les deux éléments 10 étant serrés respectivement sur deux tiges porteuses verticales 11 qui dans l'exemple illustré sont suspendues au plafond non représenté d'un local par des éléments d'ancrage 12.The illustrated device comprises a lamp or spot 1 suspended by a vertical rod 2 from a connection member 3 fixed on an elongated support or rail 4. The support 4 comprises a rigid horizontal profiled rod 5 in the form of a cylinder of revolution extending between two connecting members 6 and 7 respectively disposed at the two ends of the support. Two flexible conductive cables 8 are stretched between the members 6 and 7 so as to extend parallel to the axis of revolution 9 of the profiled rod 5, in the horizontal plane of this axis and symmetrically to one another by compared to this one. On each of connecting members 6 and 7 protrudes, opposite the other connecting member, a hooking element 10, the two elements 10 being clamped respectively on two vertical support rods 11 which in the illustrated example are suspended from the ceiling not shown in a room by anchoring elements 12.

La figure 3 illustre plus en détail l'organe de liaison 7 et les régions d'extrémités correspondantes de la tige 5 et des câbles 8. L'organe de liaison comprend deux demi-coquilles en matière plastique moulée 13 et 14 qui sont identiques à ceci près que la demi-coquille supérieure 13 présente deux trous traversants non filetés 15 pour le passage de deux vis 16, présentant des logements pour les têtes de ces vis, tandis que la demi-coquille inférieure 14 présente deux trous borgnes filetés 17 dans lesquels se vissent les vis 16 pour assurer l'assemblage mutuel des deux demi-coquilles, qui viennent s'appuyer l'une sur l'autre dans le plan horizontal contenant les deux câbles 8. A partir de ce plan sont ménagées dans chaque demi-coquille une encoche médiane 18 et deux encoches latérales 19, les deux encoches 18 définissant une ouverture traversante dans la direction de l'axe 9 pour le passage et l'immobilisation de la tige 5, et les encoches 19 définissant deux à deux des ouvertures traversantes s'étendant dans la direction de l'axe 9 pour le passage et l'immobilisation des câbles 8. Chaque demi-coquille présente, respectivement au voisinage de ses deux extrémités dans la direction latérale du support, un téton cylindrique 20 faisant saillie au-delà du plan de jonction et un trou borgne 21 ménagé à partir de ce même plan, chaque téton 20 coopérant avec le trou 21 de l'autre demi-coquille pour assurer le centrage mutuel de ces deux pièces et faciliter ainsi leur assemblage. La coquille formée par l'assemblage des deux demi-coquilles présente une forme générale cylindrique de section sensiblement elliptique dont la génératrice est parallèle à l'axe 9.FIG. 3 illustrates in more detail the connecting member 7 and the corresponding end regions of the rod 5 and of the cables 8. The connecting member comprises two molded plastic half-shells 13 and 14 which are identical to except that the upper half-shell 13 has two non-threaded through holes 15 for the passage of two screws 16, having housings for the heads of these screws, while the lower half-shell 14 has two threaded blind holes 17 in which the screws 16 are screwed to ensure the mutual assembly of the two half-shells, which come to bear one on the other in the horizontal plane containing the two cables 8. From this plane are provided in each half shell a central notch 18 and two lateral notches 19, the two notches 18 defining a through opening in the direction of the axis 9 for the passage and immobilization of the rod 5, and the notches 19 defining two to two of the through openings extending in the direction of the axis 9 for the passage and immobilization of the cables 8. Each half-shell has, respectively in the vicinity of its two ends in the lateral direction of the support, a cylindrical stud 20 projecting beyond the junction plane and a blind hole 21 formed from this same plane, each stud 20 cooperating with the hole 21 of the other half-shell to ensure the mutual centering of these two parts and thus facilitate their assembly. The shell formed by the assembly of the two half-shells has a generally cylindrical shape of substantially elliptical section, the generatrix of which is parallel to the axis 9.

L'ouverture traversante définie par les encoches 18, qui a une forme de révolution autour de l'axe 9, est formée de plusieurs régions cylindriques. L'une de ces régions, référencée 22, s'étend sur la majeure partie de la longueur de l'ouverture et débouche vers la région médiane du support. Son diamètre correspond à celui de la tige 5. Une seconde région 23, de plus grand diamètre que la région 22, s'étend sur une faible longueur entre celle-ci et une troisième région 24 ayant également un diamètre plus petit que celui de la région 23. Le diamètre de l'ouverture augmente de nouveau dans une dernière région 25 qui débouche vers l'extérieur du support. Les régions 22, 23 et 25 reçoivent respectivement la région d'extrémité de la tige 5, une rondelle d'arrêt 26 et une pièce 27 qui est représentée séparément à la figure 5. Cette pièce comprend un corps cylindrique 28 qui est partiellement logé dans la région 25 de l'ouverture et qui dépasse hors de celle-ci, et deux bossages cylindriques 29 et 30 de plus petit diamètre faisant saillie de part et d'autre du corps 28 dans la direction de l'axe 9, respectivement vers l'intérieur et vers l'extérieur du support 4, le bossage 30 étant fileté. Une encoche 31 à fond semi-cylindrique est ménagée selon un plan diamétral à partir de l'extrémité libre du bossage 30 et s'étend jusqu'au corps 28, et un trou traversant axialement la pièce présente une partie de plus petit diamètre 32 débouchant par le bossage 29 et une partie de plus grand diamètre 33 débouchant par le bossage 30, ces deux parties étant raccordées par un épaulement radial 34 situé entre le bossage 29 et le fond de l'encoche 31. Une vis 35 peut s'engager dans le trou 32, 33, sa tête s'appuyant sur l'épaulement 34, et dans le trou central de la rondelle 26, et se visser dans un trou fileté axial 36 débouchant à l'extrémité de la tige 5. Un écrou borgne 37 muni de deux trous 38 permettant sa manoeuvre au moyen d'une clé spéciale peut se visser sur le bossage 30. Les pièces 27 et 37 constituent l'élément d'accrochage 10, dont le fonctionnement sera décrit plus loin.The through opening defined by the notches 18, which has a shape of revolution around the axis 9, is formed of several cylindrical regions. One of these regions, referenced 22, extends over most of the length of the opening and leads to the middle region of the support. Its diameter corresponds to that of the rod 5. A second region 23, of larger diameter than the region 22, extends over a short length between the latter and a third region 24 also having a smaller diameter than that of the region 23. The diameter of the opening increases again in a last region 25 which opens towards the outside of the support. The regions 22, 23 and 25 respectively receive the end region of the rod 5, a locking washer 26 and a part 27 which is shown separately in FIG. 5. This part comprises a cylindrical body 28 which is partially housed in the region 25 of the opening and which projects beyond it, and two cylindrical bosses 29 and 30 of smaller diameter projecting on either side of the body 28 in the direction of the axis 9, respectively towards the inside and out of the support 4, the boss 30 being threaded. A notch 31 with a semi-cylindrical bottom is formed in a diametral plane from the free end of the boss 30 and extends to the body 28, and a hole axially passing through the part has a part of smaller diameter 32 emerging by the boss 29 and a part of larger diameter 33 emerging through the boss 30, these two parts being connected by a radial shoulder 34 located between the boss 29 and the bottom of the notch 31. A screw 35 can engage in the hole 32, 33, its head resting on the shoulder 34, and in the central hole of the washer 26, and screwing into an axial threaded hole 36 opening at the end of the rod 5. A cap nut 37 provided with two holes 38 allowing its operation by means of a special key can be screwed onto the boss 30. The parts 27 and 37 constitute the attachment element 10, the operation of which will be described later.

Chacune des ouvertures définie par les encoches 19 a également une forme de révolution, et est formée de deux régions cylindriques, une région 40 de plus petit diamètre débouchant vers l'intérieur du support 4 et une région 41 de plus grand diamètre débouchant vers l'extérieur et s'étendant sur la majeure partie de la longueur de l'ouverture. Le diamètre de la région 40 est suffisant pour permettre le passage du câble 8, et celui de la région 41 pour loger un manchon d'arrêt 42, dans lequel l'extrémité du câble est immobilisée par des vis sans tête 43 se vissant dans la paroi du manchon, et un ressort hélicoïdal de tension 44 qui entoure le câble entre le manchon 42 et l'épaulement raccordant les régions 40 et 41 de l'ouverture.Each of the openings defined by the notches 19 also has a shape of revolution, and is formed of two cylindrical regions, a region 40 of smaller diameter opening towards the inside of the support 4 and a region 41 of larger diameter opening towards the outside and extending over most of the length of the opening. The diameter of the region 40 is sufficient to allow the passage of the cable 8, and that of the region 41 for housing a stop sleeve 42, in which the end of the cable is immobilized by grub screws 43 which are screwed into the wall of the sleeve, and a tension helical spring 44 which surrounds the cable between the sleeve 42 and the shoulder connecting the regions 40 and 41 of the opening.

L'organe de liaison 6 est identique à l'organe de liaison 7, sous réserve des ressorts 44 qui peuvent y être supprimés.The connecting member 6 is identical to the connecting member 7, subject to the springs 44 which can be removed there.

L'organe de raccordement 3, illustré en détail à la figure 2, comprend également deux demi-coquilles 50 et 51 dont la forme générale et les dimensions extérieures sont sensiblement les mêmes que celles des demi-coquilles 13 et 14 et qui viennent s'appuyer l'une sur l'autre dans le plan contenant les deux câbles 8, ces deux demi-coquilles présentant à partir de ce plan des encoches 52, 53 définissant des ouvertures traversantes pour le passage de la tige 5 et du câble 8. Des moyens de centrage analogues à ceux des demi-coquilles 13 et 14 sont prévus sur les demi-coquilles 50 et 51. En revanche leur assemblage mutuel est assuré par des ressorts 54 qui viennent se loger dans des évidements 55, adjacents au plan de jonction, prévu extérieurement dans les deux demi-coquilles, de façon à permettre un montage et un démontage faciles. L'extrémité supérieure de la tige 2 de suspension de la lampe pénètre dans une bague filetée intérieurement 56 où elle est immobilisée par une vis radiale. La bague 56 est elle-même vissée sur une douille 57 présentant une partie inférieure filetée extérieurement et dont la partie supérieure élargie est retenue à l'intérieur de la demi-coquille inférieure 51 qui est creuse. L'ensemble formé par la bague 56 et la douille 57 est monté sur la demi-coquille 51 par des moyens connus permettant un pivotement autour de l'axe de la tige 2 sur un angle proche de 360° pour l'orientation de la lampe 1. Cette dernière est alimentée en électricité par deux câbles gainés 58 qui traversent axialement la tige creuse 2, la bague 56 et la douille 57 et sont reliés par des cosses 59 qu'ils présentent à leurs extrémités à des organes de connexion 60 découpés dans de la tôle métallique. Chaque organe de connexion 60 présente une portion en forme de bande 61 qui s'étend dans la direction longitudinale du support 4 et est fixée élastiquement dans la demi-coquille inférieure 51 par des moyens connus non représentés en particulier de façon à reposer sur une surface d'appui 62 de cette demi-coquille et à faire saillie élastiquement dans l'une des ouvertures traversantes définies par les encoches 53 pour le passage des câbles 8.The connecting member 3, illustrated in detail in FIG. 2, also comprises two half-shells 50 and 51 whose general shape and external dimensions are substantially the same as those of the half-shells 13 and 14 and which come press one on the other in the plane containing the two cables 8, these two half-shells having from this plane notches 52, 53 defining through openings for the passage of the rod 5 and the cable 8. Des centering means similar to those of the half-shells 13 and 14 are provided on the half-shells 50 and 51. On the other hand, their mutual assembly is ensured by springs 54 which are housed in recesses 55, adjacent to the junction plane, provided externally in the two half-shells, so as to allow easy assembly and disassembly. The upper end of the lamp suspension rod 2 enters an internally threaded ring 56 where it is immobilized by a radial screw. The ring 56 is itself screwed onto a bushing 57 having an externally threaded lower part and whose enlarged upper part is retained inside the lower half-shell 51 which is hollow. The assembly formed by the ring 56 and the socket 57 is mounted on the half-shell 51 by known means allowing pivoting around the axis of the rod 2 at an angle close to 360 ° for the orientation of the lamp 1. The latter is supplied with electricity by two sheathed cables 58 which pass axially through the hollow rod 2, the ring 56 and the sleeve 57 and are connected by lugs 59 which they present at their ends to connection members 60 cut out from sheet metal. Each connection member 60 has a strip-shaped portion 61 which extends in the direction longitudinal of the support 4 and is fixed elastically in the lower half-shell 51 by known means not shown in particular so as to rest on a bearing surface 62 of this half-shell and to protrude elastically in one of the openings through defined by the notches 53 for the passage of cables 8.

Le montage du support 4 s'effectue de la façon suivante.The mounting of the support 4 is carried out as follows.

Les câbles 8 étant coupés à la longueur voulue, on y enfile les ressorts 44 et on fixe une extrémité de chacun d'eux dans un manchon 42 au moyen des vis 43. On place les manchons 42 et les ressorts 44 dans les régions 41 des encoches 19 de la demi-coquille inférieure 14, les câbles passant dans les régions 40, et l'extrémité de la tige 5 et la rondelle 26 respectivement dans les régions 22 et 23 de l'encoche 18. On positionne alors la demi-coquille supérieure 13 sur la demi-coquille inférieure 14 à l'aide des tétons 20 et des trous 21, et on assemble ces deux pièces au moyen des vis 16. On engage alors la pièce 27 dans la région 25 de l'ouverture traversante médiane de l'organe de liaison et la vis 35 à travers la pièce 27 et la rondelle 26 pour la visser dans le trou 36 de la tige 5. Ce vissage amène l'extrémité de la tige en butée sur la rondelle 26 et immobilise la tige 5 et la pièce 27 par rapport aux deux demi-coquilles. On effectue ensuite les mêmes opérations à l'autre extrémité du support 4, une traction étant exercée sur les câbles 8, en comprimant les ressorts 44, pour venir loger les manchons 42 dans les régions 41 des encoches à la seconde extrémité.The cables 8 being cut to the desired length, the springs 44 are threaded therein and one end of each of them is fixed in a sleeve 42 by means of screws 43. The sleeves 42 and the springs 44 are placed in the regions 41 of the notches 19 of the lower half-shell 14, the cables passing through the regions 40, and the end of the rod 5 and the washer 26 respectively in the regions 22 and 23 of the notch 18. The half-shell is then positioned upper 13 on the lower half-shell 14 using the pins 20 and the holes 21, and these two parts are assembled by means of the screws 16. The part 27 is then engaged in the region 25 of the median through opening of the connecting member and the screw 35 through the part 27 and the washer 26 to screw it into the hole 36 of the rod 5. This screwing brings the end of the rod into abutment on the washer 26 and immobilizes the rod 5 and the part 27 relative to the two half-shells. The same operations are then carried out at the other end of the support 4, a traction being exerted on the cables 8, by compressing the springs 44, in order to accommodate the sleeves 42 in the regions 41 of the notches at the second end.

La fixation du support 4 sur les tiges porteuse 11 s'effectue en introduisant ces dernières dans les encoches 31 des pièces 27 et en vissant les écrous 37 sur les bossages 30 pour serrer chaque tige 11 entre l'écrou et le fond de l'encoche 31. Auparavant, l'orientation de chaque élément de liaison 6, 7 par rapport à l'encoche 31 correspondante peut être ajustée en desserrant légèrement la vis 35 pour permettre un pivotement de la pièce 28, la vis étant ensuite resserrée dans la position voulue.The support 4 is fixed to the support rods 11 by inserting the latter into the notches 31 of the parts 27 and by screwing the nuts 37 on the bosses 30 to tighten each rod 11 between the nut and the bottom of the notch 31. Previously, the orientation of each connecting element 6, 7 with respect to the corresponding notch 31 can be adjusted by slightly loosening the screw 35 to allow pivoting of the part 28, the screw then being tightened in the desired position .

En utilisation normale, tous les composants décrits en relation avec la figure 2 restent solidaires les uns des autres, à l'exception de la demi-coquille supérieure 50 et des deux ressorts d'assemblage 54. Pour mettre en place la lampe sur le support, l'en retirer ou la déplacer le long de celui-ci, il suffit de démonter ces trois derniers composants. Lors de la mise en place sur le support, on amène les deux demi-coquilles de part et d'autre de celui-ci de façon que la tige 5 et les câbles 8 viennent se loger dans les encoches 52 et 53. Les lames de contact 61 sont alors déformées élastiquement par les câbles et assurent un bon contact électrique avec ceux-ci. Les diamètres des encoches 52 et 53 correspondent à ceux de la tige et des câbles de façon à assurer un léger serrage de ceux-ci et une position stable de la lampe sur le support.In normal use, all the components described in relation to FIG. 2 remain integral with one another, with the exception of the upper half-shell 50 and the two assembly springs 54. To place the lamp on the support , remove it or move it along it, just disassemble these last three components. When positioning on the support, the two half-shells are brought on either side of it so that the rod 5 and the cables 8 are received in the notches 52 and 53. The blades of contact 61 are then elastically deformed by the cables and ensure good electrical contact with them. The diameters of the notches 52 and 53 correspond to those of the rod and of the cables so as to ensure a slight tightening of these and a stable position of the lamp on the support.

Les câbles d'alimentation 8 peuvent être reliés à une source à très basse tension non représentée par des fils gainés 70 (figure 1) qui peuvent s'engager chacun dans un manchon 42, par l'extrémité libre de celui-ci faisant saillie par rapport à l'organe de liaison 6 ou 7 comme montré à la figure 4, et y être fixés et reliés électriquement par celle des vis 43 la plus proche de cette extrémité, les autres vis 43 étant utilisées pour le serrage et la liaison électrique du câble 8. Les deux fils 70 peuvent être reliés aux câbles à la même extrémité du support, comme montré à la figure 1, ou à ses deux extrémités respectivement. Ils peuvent ensuite passer à l'intérieur de la ou des tiges porteuses 11, qui sont alors creuses, ou être fixés à l'extérieur et le long de celles-ci pour être raccordés au plafond à un circuit d'alimentation.The power cables 8 can be connected to a very low voltage source not shown by sheathed wires 70 (FIG. 1) which can each engage in a sleeve 42, by the free end of the latter projecting by relative to the connecting member 6 or 7 as shown in Figure 4, and be fixed and electrically connected by that of the screws 43 closest to this end, the other screws 43 being used for tightening and electrical connection of the cable 8. The two wires 70 can be connected to the cables at the same end of the support, as shown in FIG. 1, or at its two ends respectively. They can then pass inside the one or more supporting rods 11, which are then hollow, or be fixed outside and along these to be connected to the ceiling to a supply circuit.

Les tiges porteuses 11, au lieu d'être suspendues au plafond comme représenté, peuvent s'élever à partir du sol, ou s'étendre du sol au plafond. Elles peuvent également être placées horizontalement ou obliquement. Le cas échéant la position du support 4 le long des tiges porteuses peut être réglée en desserrant et en resserrant les écrous 37. L'une des tiges 11 peut être supprimée, le support 4 étant monté en porte-à-faux sur une seule tige. Deux supports 4 ou plus peuvent par ailleurs être montés sur une même tige porteuse dans des directions longitudinales identiques ou différentes, deux supports pouvant en particulier être disposés sensiblement dans le prolongement l'un de l'autre. Enfin les deux tiges porteuses 11 peuvent être remplacées par des câbles porteurs tendus verticalement, à condition que le centre de gravité du dispositif soit placé dans le plan contenant ces câbles de façon que ceux-ci ne subissent pas de contraintes de flexion. Les câbles 8 peuvent quant à eux être remplacés par des conducteurs profilés rigides, notamment dans le cas d'un support ou rail de plusieurs mètres de longueur.The supporting rods 11, instead of being suspended from the ceiling as shown, can rise from the ground, or extend from the ground to the ceiling. They can also be placed horizontally or obliquely. If necessary, the position of the support 4 along the support rods can be adjusted by loosening and tightening the nuts 37. One of the rods 11 can be removed, the support 4 being mounted in cantilever on a single rod . Two supports 4 or more can also be mounted on the same support rod in identical or different longitudinal directions, two supports which can in particular be arranged substantially in the extension of one another. Finally, the two carrying rods 11 can be replaced by carrying cables stretched vertically, provided that the center of gravity of the device is placed in the plane containing these cables so that they do not undergo bending stresses. The cables 8 can in turn be replaced by rigid profiled conductors, in particular in the case of a support or rail of several meters in length.
