Description

La présente invention a pour objet un dispositif d'éclairage de sécurité comportant un boîtier tubulaire transparent hébergeant des moyens d'éclairage d'un élément de signalisation visuelle, ledit boîtier étant fermé à ses extrémités par un premier et un second embouts dont au moins un est conçu apte à permettre un raccordement électrique desdits moyens d'éclairage.The present invention relates to a safety lighting device comprising a transparent tubular housing housing means for illuminating a visual signaling element, said housing being closed at its ends by a first and a second end of which at least one is designed able to allow electrical connection of said lighting means.

De manière classique, les dispositifs d'éclairage de sécurité, ou blocs autonomes d'éclairage de sécurité, ont pour vocation de continuer à diffuser un signal lumineux en cas d'interruption accidentelle de l'éclairage normal, et sont donc pourvus de moyens d'alimentation électrique autonomes, tels qu'une batterie assurant leur fonctionnement en cas de coupure de courant. La réglementation actuelle impose leur installation dans les locaux à usage public en vue de permettre la circulation des personnes et assurer, si nécessaire, leur évacuation en limitant tout risque de mouvement de panique. Ils doivent également permettre, le cas échéant, l'arrivée rapide et par conséquent une intervention efficace des secours.Conventionally, safety lighting devices, or autonomous safety lighting units, are intended to continue to broadcast a light signal in case of accidental interruption of normal lighting, and are therefore provided with means of autonomous power supply, such as a battery ensuring their operation in the event of a power failure. Current regulations require that they be placed in public places to allow the movement of people and, if necessary, to evacuate them by limiting any risk of panic. They must also allow, if necessary, the rapid arrival and consequently an effective intervention of the helpers.

En somme, de tels dispositifs jouent le rôle de balises régulièrement réparties sur un trajet s'étendant entre une issue de secours et un lieu d'incident et comportent à cet effet des indications lumineuses permettant aux usagers de s'orienter promptement, y compris en cas d'éventuelle semi-obscurité, voire d'obscurité totale, en vue d'évacuer les lieux ou de s'y rendre, en ce qui concerne les secouristes et autres intervenants. De toute évidence, l''éclairage généré doit préférentiellement être uniforme et tel qu'il permet également au public de repérer d'éventuels obstacles et changements de direction.In short, such devices act as beacons regularly distributed on a path extending between an emergency exit and an incident site and for this purpose include luminous indications enabling users to orient themselves promptly, including in the event of semi-darkness, or even complete darkness, in order to evacuate the premises or to go there, as regards rescuers and other interveners. Obviously, the lighting generated should preferably be uniform and such that it also allows the public to identify possible obstacles and changes of direction.

Il convient également de noter qu'une des extrémités 50, 60 des première et seconde coques hémicylindriques 5, 6 est bordée par une collerette 52, 62 dont la paroi interne porte quatre organes tubulaires 53, 63. Ces derniers autorisent la fixation du premier embout 20 sur la première coque hémicylindrique 5 et celle du second embout 21 sur la seconde coque hémicylindrique 6 au travers, à chaque fois, de quatre vis 12 traversant des orifices formés de manière appropriée sur lesdits premier et second embouts 20, 21.It should also be noted that one of the ends 50, 60 of the first and second hemicylindrical shells 5, 6 is bordered by a flange 52, 62 whose inner wall carries four tubular members 53, 63. These allow the attachment of the first endpiece On the first hemi-cylindrical shell 5 and the second hull 21 on the second hemi-cylindrical shell 6 through, in each case, four screws 12 passing through orifices suitably formed on said first and second ends 20, 21.

L'autre extrémité 51, 61 de chaque coque hémicylindrique 5, 6 est par ailleurs également pourvue d'un organe tubulaire 54, 64 et permettant cette fois-ci la fixation du second embout 21 sur la première coque hémicylindrique 5 et du premier embout 20 sur la seconde coque hémisphérique 6, au travers d'une vis 120 traversant un orifice formé de manière appropriée sur lesdits premier et second embouts 20, 21.The other end 51, 61 of each hemi-cylindrical shell 5, 6 is also also provided with a tubular member 54, 64 and this time allowing the attachment of the second tip 21 on the first hemi-cylindrical shell 5 and the first end 20 on the second hemispherical shell 6, through a screw 120 passing through an orifice formed appropriately on said first and second end pieces 20, 21.

Le dispositif d'éclairage de sécurité 1 selon l'invention comporte par ailleurs, intercalés entre chacun des premiers embouts 20, 21 et chacune des collerettes 52, 62 prolongeant les coques hémisphériques 5, 6, une carte de circuit imprimé annulaire 9 portant au moins une diode électroluminescente diffusant de manière homogène, via un guide lumière de forme annulaire 11, une lumière de forme annulaire, et un joint d'étanchéité 12. Ce dernier se présente sous la forme d'un disque, bordé par une paroi périphérique, et comportant, dans la variante illustrée, deux zones sécables 130. La rupture de l'une et/ou l'autre de celles-ci entraîne la formation d'un ou deux orifices pour le passage d'un ou deux câbles de raccordement électrique.The safety lighting device 1 according to the invention further comprises, interposed between each of the first end pieces 20, 21 and each of the flanges 52, 62 extending the hemispherical shells 5, 6, an annular printed circuit board 9 carrying at least a light-emitting diode which diffuses, in a homogeneous manner, via an annular light guide 11, an annular-shaped light, and a seal 12. This latter is in the form of a disc, bordered by a peripheral wall, and comprising, in the variant shown, two breakable zones 130. The rupture of one and / or the other of these causes the formation of one or two holes for the passage of one or two electrical connection cables.

Par ailleurs, chacun desdits premier et second embouts 20, 21 comporte également deux orifices 13 situés vis-à-vis des zones sécables 130 du joint 12 et permettant le passage d'un ou deux câbles pour le raccordement électrique des diodes électroluminescentes portés par ladite au moins une carte de circuit imprimé 3, et destinés à être branchés sur un connecteur 14 solidaire de ladite carte de circuit imprimé 3 (cf. fig. 3).Furthermore, each of said first and second end pieces 20, 21 also comprises two orifices 13 situated opposite the breakable zones 130 of the gasket 12 and allowing the passage of one or two cables for the electrical connection of the light emitting diodes carried by said at least one printed circuit board 3, and intended to be connected to a connector 14 integral with said printed circuit board 3 (cf. Fig. 3 ).

Grâce à la structure du dispositif d'éclairage de sécurité 1 qui vient d'être décrite, le raccordement électrique de celui-ci est simplifié. Par ailleurs, cette structure permet avantageusement d'éviter le recours à une boîte de dérivation externe en cas de branchement en série de plusieurs dispositifs 1 selon l'invention, et donc d'en simplifier les opérations de câblage électrique.Thanks to the structure of the safety lighting device 1 which has just been described, the electrical connection thereof is simplified. Furthermore, this structure advantageously avoids the use of an external junction box in case of serial connection of several devices 1 according to the invention, and therefore to simplify the electrical wiring operations.

En effet, en référence notamment aux figures 2 et 3, il suffit, lors de l'installation d'un dispositif 1 selon l'invention, de dévisser par exemple la vis reliant, au travers de l'organe 64, la seconde coque hémicylindrique 6 au premier embout 20. Ce dernier reste alors toujours fixé à la première coque hémicylindrique 5 et forme avec cette dernière un premier module 24 pouvant être séparé d'un second module 25 formé par la seconde coque hémicylindrique 6 et le second embout 21. Ainsi, le premier module 24 et/ou le second module 25 peut/peuvent être au moins partiellement extrait(s) du boîtier tubulaire 2. Ceci permet d'offrir un accès au connecteur 14 solidaire de la carte de circuit imprimé 3 pour y brancher un câble électrique introduit via un des orifices 13 que comportent les premier et second embouts 20, 21, et traversant un orifice du joint 12. Par la même occasion, un raccordement électrique en série d'un premier dispositif d'éclairage de sécurité 1 avec un second dispositif d'éclairage de sécurité 1 peut éventuellement être effectué, en branchant sur le connecteur 14 un second câble électrique introduit au travers du second orifice 13 que comporte les embouts 20, 21, et au travers du second orifice formé dans le joint 12 après rupture de la seconde zone sécable 130.Indeed, with reference in particular to figures 2 and 3 it is sufficient, during the installation of a device 1 according to the invention, to unscrew for example the screw connecting, through of the member 64, the second hemi-cylindrical shell 6 to the first nozzle 20. The latter then remains fixed to the first hemi-cylindrical shell 5 and forms with the latter a first module 24 which can be separated from a second module 25 formed by the second Hemi-cylindrical shell 6 and the second nozzle 21. Thus, the first module 24 and / or the second module 25 can be at least partially extracted from the tubular housing 2. This makes it possible to provide access to the connector 14 secured to the printed circuit board 3 to connect an electric cable introduced through one of the orifices 13 that comprise the first and second end pieces 20, 21, and through an orifice of the seal 12. At the same time, a series electrical connection of a first safety lighting device 1 with a second safety lighting device 1 may optionally be performed, by connecting to the connector 14 a second electric cable introduced through the second orifice 13 that comprises the end pieces 20, 21, and through the second orifice formed in the joint 12 after rupture of the second breakable zone 130.

Comme illustré aux figures 2 et 4, les deux coques hémicylindriques 5, 6 présentent en outre des moyens de maintien en position en face de la fenêtre 8 de l'étiquette 4 (non illustrée à la figure 4 pour des raisons de lisibilité).As illustrated in figures 2 and 4 the two hemicylindrical hulls 5, 6 also have means for holding in position in front of the window 8 of the label 4 (not shown in FIG. figure 4 for reasons of readability).

A cet effet, chacune des deux coques hémicylindriques 5, 6 comporte deux rebords 140 en « L » s'étendant perpendiculairement à chacun de ses bords longitudinaux, depuis sa face externe 70. En fait, lesdits rebords 140 en « L » ménagent sur chaque coque 5, 6 deux coulisses longitudinales 17, s'étendant de part et d'autre de ladite coque 5, 6 entre sa face externe 70 et une paroi 18 du rebord 14 en « L ». Chacune des coulisses 17 est en outre pourvue d'une rangée de pattes 19 s'étendant depuis son fond, dans un plan parallèle à la paroi 18 du rebord 14 en « L », l'extrémité supérieure d'au moins certaines desdites pattes 19 étant reliée à la face externe 70 de la coque hémicylindrique 5, 6 au travers d'une languette arquée 22 s'étendant dans un plan perpendiculaire auxdites pattes 19.For this purpose, each of the two hemicylindrical hulls 5, 6 comprises two "L" -shaped rims 140 extending perpendicularly to each of its longitudinal edges, from its outer face 70. In fact, said "L" -shaped edges 140 are sparing on each shell 5, 6 two longitudinal slides 17, extending on either side of said shell 5, 6 between its outer face 70 and a wall 18 of the flange 14 in "L". Each of the slides 17 is further provided with a row of tabs 19 extending from its bottom, in a plane parallel to the wall 18 of the flange 14 at "L", the upper end of at least some of said tabs 19. being connected to the outer face 70 of the semi-cylindrical shell 5, 6 through an arcuate tongue 22 extending in a plane perpendicular to said tabs 19.

Par ailleurs, dans la variante de réalisation illustrée, les pattes 19 et languettes arquées 22 de chacune des coulisses 17 sont situées les unes en face des autres.Furthermore, in the embodiment shown, the tabs 19 and tabs arcuate 22 of each of the slides 17 are located opposite each other.

Une telle structure permet de ménager sur chacune des coulisses 17, entre la paroi 18 de chaque rebord 14 en « L » et les pattes 19, un interstice 23 dont la largeur correspond sensiblement à l'épaisseur d'une étiquette 4 et dans lequel les chants longitudinaux de cette dernière peuvent être engagés. L'étiquette 4 ainsi disposée se trouve alors non seulement bloquée en position face à la fenêtre 8 mais également plaquée contre les languettes arquées 22, ce qui permet d'éviter toute éventuelle déformation de l'étiquette 4 qui pourrait nuire à sa longévité et son aspect esthétique.Such a structure makes it possible to provide on each of the slides 17, between the wall 18 of each rim 14 in "L" and the tabs 19, a gap 23 whose width substantially corresponds to the thickness of a label 4 and in which the Longitudinal songs of the latter can be engaged. The label 4 thus disposed is then not only locked in position facing the window 8 but also pressed against the arcuate tongues 22, which avoids any possible deformation of the label 4 which could adversely affect its longevity and its aesthetic appearance.

Il ressort ainsi clairement de ce qui précède que l'invention permet d'atteindre les objectifs fixés en préambule, à savoir notamment, faciliter le raccordement électrique d'un dispositif d'éclairage de sécurité de type tubulaire en permettant un accès à l'espace compris entre les deux coques hémicylindriques 5, 6 par l'un ou l'autre des embouts 20, 21 et améliorer sa longévité et son aspect esthétique, en prévoyant des moyens de maintien en position du/des éléments de signalisation visuelle évitant qu'il(s) ne se déplace(nt) ou ne se déforme(nt). Par ailleurs, il est avantageusement possible d'obtenir, selon le cas, un éclairage d'un seul élément de signalisation visuelle ou de deux éléments de signalisation visuelle orientés dans des directions opposées à l'intérieur du boîtier tubulaire.It is thus clear from the foregoing that the invention makes it possible to achieve the objectives set in the preamble, namely in particular to facilitate the electrical connection of a tubular-type safety lighting device by allowing access to the space between the two hemicylindrical hulls 5, 6 by one or the other of the end pieces 20, 21 and improve its longevity and its aesthetic appearance, by providing means for maintaining in position the visual signaling element / elements avoiding that it (s) does not move (s) or deforms (s). Moreover, it is advantageously possible to obtain, as the case may be, illumination of a single visual signaling element or of two visual signaling elements oriented in opposite directions inside the tubular housing.

Ainsi, afin de permettre la lecture de deux étiquettes 4 orientées dans des directions opposées de part et d'autre d'un boîtier tubulaire 2, ce qui est notamment particulièrement avantageux pour utiliser un même dispositif d'éclairage de sécurité 1 pour baliser un trajet aller et un trajet retour, il est possible de prévoir que le corps tubulaire 7 formé par les deux coques hémicylindriques 5, 6, renferme deux cartes de circuit imprimé 3 portant chacune au moins une diode électroluminescente orientée pour l'une vers une fenêtre 8 que comporte la première coque hémicylindrique 5 et pour l'autre vers une fenêtre 8 que comporte la seconde coque hémicylindrique 6.Thus, to allow the reading of two labels 4 oriented in opposite directions on either side of a tubular housing 2, which is particularly advantageous for using the same safety lighting device 1 to mark a path go and a return path, it is possible to provide that the tubular body 7 formed by the two hemicylindrical shells 5, 6, encloses two printed circuit boards 3 each carrying at least one light emitting diode oriented for one towards a window 8 that has the first hemi-cylindrical shell 5 and for the other to a window 8 that includes the second hemi-cylindrical shell 6.
