The ring 30 comprises means interacting with the support, making it possible to lock the ring and unlock it by relative rotation with respect to the support, and at least one bent elastic blade 32 intended to clamp the reflector elastically, making it possible to insert and retract the reflector by sideways movement, once the ring has been separated from the support.

Description

Appareil d'éclairage à réflecteur porte-lampe amovible
L'invention concerne les appareils d'éclairage du type comprenant un support annulaire, un réflecteur de forme évasée muni d'une lampe, et une bague de maintien du réflecteur dans le support. Elle trouve une application particulièrement importante, mais nullement exclusive, dans le domaine des appareils d'éclairage utilisant des lampes de petite taille fonctionnant sous faible tension, encastrables dans le plafond de locaux ou pouvant équiper des luminaires.Removable lamp holder reflector light fixture
The invention relates to lighting devices of the type comprising an annular support, a flared shape reflector provided with a lamp, and a ring for holding the reflector in the support. It finds a particularly important, but by no means exclusive, application in the field of lighting fixtures using small lamps operating under low voltage, recessed into the ceiling of premises or which can be fitted with luminaires.

Des appareils de ce type, à lampe dichroique, sont de plus en plus utilisés, pour l'éclairage de vitrines et de lieux de passage notamment. Ils sont peu encombrants, donc peu visibles. Devices of this type, with dichroic lamp, are increasingly used, for the lighting of shop windows and places of passage in particular. They are compact, therefore not very visible.

Les appareils d'éclairage actuels du type ci-dessus présentent l'inconvénient de rendre difficile l'accès a la lampe, par exemple pour la remplacer. De plus, dans certains d'entre eux, on fait tourner le réflecteur et les fils électriques de raccordement lorsqu'on démonte l'appareil pour accéder à la lampe, ce qui peut provoquer des ruptures ou des arrachements de fils. Current lighting fixtures of the above type have the drawback of making access to the lamp difficult, for example to replace it. In addition, in some of them, the reflector and the connecting electrical wires are rotated when the device is dismantled to access the lamp, which can cause breaks or tearing of the wires.

L'invention vise a fournir un appareil d'éclairage du type ci-dessus défini répondant mieux que ceux antérieurement connus aux exigences de la pratique, notamment en ce qu'il donne un accès facile et commode à la lampe. Dans ce but, l'invention propose notamment un appareil d'éclairage du type ci-dessus défini, caractérisé en ce que la bague comporte des moyens coopérant avec le support, permettant de verrouiller la bague et de la déverrouiller par rotation relative par rapport au support, et au moins une lame élastique cintrée destinée à enserrer élastiquement le réflecteur, permettant d'introduire et de retirer le réflecteur par déplacement latéral, une fois la bague séparée du support.  The invention aims to provide a lighting device of the above defined type which better meets those previously known than the requirements of practice, in particular in that it gives easy and convenient access to the lamp. To this end, the invention proposes in particular a lighting device of the type defined above, characterized in that the ring comprises means cooperating with the support, making it possible to lock the ring and to unlock it by relative rotation relative to the support, and at least one bent elastic blade intended to resiliently enclose the reflector, making it possible to introduce and remove the reflector by lateral displacement, once the ring has been separated from the support.

La bague peut comporter un épaulement ou une margelle destinée à servir d'appui à un rebord radial du réflecteur ; un l'épaulement supplémentaire peut être prévu dans la bague pour retenir une glace ou un écran sous le réflecteur. The ring may include a shoulder or a coping intended to serve as a support for a radial rim of the reflector; an additional shoulder may be provided in the ring to retain a lens or a screen under the reflector.

Le support et la bague conservent dans tous les cas une forme simple et peuvent être constitués en divers matériaux. On peut notamment utiliser des pièces de fonderie en alliage léger. La lame est généralement en acier à ressort. The support and the ring keep in all cases a simple shape and can be made of various materials. One can in particular use light alloy casting parts. The blade is generally made of spring steel.

L'invention sera mieux comprise à la lecture de la description qui suit d'un mode particulier de réalisation de l'invention, donné a titre d'exemple non limitatif. La description se réfère aux dessins qui l'accompagnent, dans lesquels
- la Figure 1 est une vue en élévation et en coupe partielle, montrant l'ensemble d'un appareil suivant l'invention ;
- la Figure 2 est une vue de détail éclatée, en élévation, montrant la bague et une fraction du support de l'appareil, en coupe partielle
- la Figure 3 est une vue de dessus de la bague au repos.The invention will be better understood on reading the following description of a particular embodiment of the invention, given by way of non-limiting example. The description refers to the accompanying drawings, in which
- Figure 1 is an elevational view in partial section, showing the assembly of an apparatus according to the invention;
- Figure 2 is an exploded detail view, in elevation, showing the ring and a fraction of the support of the device, in partial section
- Figure 3 is a top view of the ring at rest.

L'appareil montré a titre d'exemple sur les
Figures a une constitution générale similaire a celle décrite dans la demande FR 86 03998 de la demanderesse.The device shown as an example on the
Figures has a general constitution similar to that described in application FR 86 03998 of the applicant.

Il comporte un support annulaire 10, en forme de virole cylindrique munie d'un rebord 14 permettant d'appuyer l'appareil contre un élément de structure 12. Des lames élastiques 16, fixees en leur milieu par des rivets 17 a la virole, permettent de coincer le support 10 dans un trou ménagé dans l'élément de structure 12. Ce support annula-ire sera généralement constitué par une pièce de fonderie en alliage léger, tandis que les lames seront en acier à ressort.It comprises an annular support 10, in the form of a cylindrical shell provided with a flange 14 making it possible to press the device against a structural element 12. Elastic blades 16, fixed in their middle by rivets 17 to the shell, allow to wedge the support 10 in a hole in the structural element 12. This annular-ire support will generally consist of a light alloy foundry piece, while the blades will be made of spring steel.

L'appareil est destiné à recevoir un réflecteur 18 muni d'une lampe 20 et, lorsque l'appareil est monté, d'un connecteur 22 de raccordement. Le réflecteur 18 se présente sous forme d'une calotte évasée 24 terminée par un rebord 26 d'appui, dont la présence n'est pas indispensable, et d'un prolongement 28 destiné a recevoir le culot de la lampe. La pièce support 10 a un diamètre interne tel qu'elle livre passage au réflecteur 18 et une surface externe pouvant comporter des cannelures de renforcement (non représentées). The device is intended to receive a reflector 18 provided with a lamp 20 and, when the device is mounted, with a connector 22 for connection. The reflector 18 is in the form of a flared cap 24 terminated by a support rim 26, the presence of which is not essential, and an extension 28 intended to receive the base of the lamp. The support piece 10 has an internal diameter such that it gives passage to the reflector 18 and an external surface which may include reinforcement grooves (not shown).

L'appareil comporte encore une bague 30 destinée a retenir le réflecteur et a se verrouiller dans le support 10. La bague 30 sera généralement une pièce de fonderie en alliage léger. Elle comporte un corps rigide annulaire 31, portant des moyens de verrouillage sur le support, et des moyens désarmables de retenue du réflecteur 18, autorisant l'enlèvement latéral de ce dernier. The device also comprises a ring 30 intended to retain the reflector and to lock in the support 10. The ring 30 will generally be a light alloy foundry piece. It comprises an annular rigid body 31, carrying locking means on the support, and disarmable means for retaining the reflector 18, authorizing the lateral removal of the latter.

Dans le mode de réalisation illustré, ces moyens désarmables comportent une lame élastique cintrée 32 dont la partie médiane est emprisonnée par passage dans des fentes d'une zone en saillie 34 de la bague et dont les bras ont une forme telle qu'ils enserrent élastiquement la partie basse du réflecteur, immédiatement au-dessus du rebord 26, lorsque le réflecteur est inséré. Au repos, les deux bras de la lame 32 laissent subsister une brèche de largeur suffisante pour qu'il soit possible d'introduire le réflecteur en le déplaçant latéralement, dans le sens indiqué par la flèche f sur la Figure 2, mais assez réduite pour retenir ensuite le réflecteur. Dans la pratique, cela implique que la brèche qui existe entre les extrémités de la lame lorsque le réflecteur est complètement inséré ait un développement angulaire compris entre 60 et 100 environ.In the illustrated embodiment, these disarmable means comprise a curved elastic blade 32, the middle part of which is trapped by passing through slots in a projecting zone 34 of the ring and the arms of which have a shape such that they resiliently enclose the lower part of the reflector, immediately above the rim 26, when the reflector is inserted. At rest, the two arms of the blade 32 leave a gap of sufficient width so that it is possible to introduce the reflector by moving it laterally, in the direction indicated by the arrow f in FIG. 2, but small enough to then retain the reflector. In practice, this implies that the gap which exists between the ends of the strip when the reflector is fully inserted has an angular development of between approximately 60 and 100.

La bague 30 montrée sur les dessins comporte, sur la moitié de son pourtour munie de la zone en saillie 34, un rebord 36 qui laisse subsister une margelle 38 de niveau avec la face supérieure du reste de la bague. The ring 30 shown in the drawings comprises, on the half of its periphery provided with the projecting zone 34, a flange 36 which leaves a coping 38 level with the upper face of the rest of the ring.

Pour permettre d'interposer une glace, un filtre ou un écran sur le faisceau de la lampe, la bague comporte avantageusement un épaulement interne 40 dont la distance 18 à la margelle est supérieure à l'épaisseur prévue pour l'élément interposé. To allow interposing a lens, a filter or a screen on the beam of the lamp, the ring advantageously comprises an internal shoulder 40 whose distance 18 to the coping is greater than the thickness provided for the interposed element.

Les moyens de verrouillage de la bague 30 sur le support 10 comportent, dans le mode de réalisation illustré, deux ergots 42 solidaires de la bague, placés au-dessus d'un rebord inférieur 44 de cette dernière. The locking means of the ring 30 on the support 10 comprise, in the illustrated embodiment, two lugs 42 integral with the ring, placed above a lower flange 44 of the latter.

Sur le support 10 est prévue une collerette- radiale interne 44 dans laquelle sont ménagées des brèches 46 destinées à livrer passage aux ergots 42. Des bossages 48 (Figure 3), constituant des butées pour les ergots, limitent le debattement angulaire de la bague de verrouillage. Des nervures 50 sont avantageusement ménagées a la partie inférieure de cette dernière pour en faciliter la rotation manuelle.On the support 10 is provided an internal radial flange 44 in which are provided gaps 46 intended to give passage to the pins 42. Bosses 48 (FIG. 3), constituting stops for the pins, limit the angular movement of the ring of locking. Ribs 50 are advantageously provided at the lower part of the latter to facilitate manual rotation.

Le mode de montage et de démontage de l'appareil découle directement de la description qui précède. Pour changer une ampoule sur un appareil en place, on déverrouille la bague en la faisant tourner. La bague descend en entrainant le réflecteur 18. A condition qu'on ait donné aux fils de raccordement une longueur suffisante, l'ensemble se dégage complètement du support 10. Il suffit alors de faire glisser le réflecteur latéralement hors de la lame élastique cintrée 32 formant pince pour pouvoir accéder a l'ampoule et la remplacer. Le réflecteur est ensuite glissé de nouveau en place, derrière la glace qui repose éventuellement sur l'épaulement 40 de la bague. L'ensemble bagueréflecteur est soulevé dans une orientation telle que les ergots 40 passent a travers les brèches 46. I1 suffit alors de faire tourner la bague d'un quart de tour pour la verrouiller. The method of mounting and dismounting the device follows directly from the above description. To change a bulb on a device in place, you unlock the ring by rotating it. The ring descends, driving the reflector 18. Provided that the connecting wires have been given a sufficient length, the assembly is completely disengaged from the support 10. It then suffices to slide the reflector laterally out of the bent elastic blade 32 forming a clamp to be able to access and replace the bulb. The reflector is then slid back into place, behind the glass which possibly rests on the shoulder 40 of the ring. The reflector ring assembly is raised in an orientation such that the lugs 40 pass through the gaps 46. I1 then suffices to rotate the ring a quarter of a turn to lock it.

La face supérieure de la collerette interne 44 peut avoir une légère pente pour empêcher le déverrouillage en cas de vibrations. Dans le cas montré en Figure 1, on voit qu'un chambrage est ménage dans la face inférieure du support 10 de façon que la face inférieure de la bague se trouve de nouveau avec celle du support.  The upper face of the internal flange 44 may have a slight slope to prevent unlocking in the event of vibrations. In the case shown in Figure 1, we see that a recess is formed in the underside of the support 10 so that the underside of the ring is again with that of the support.
