Description

La présente invention concerne un luminaire encastrable.The present invention relates to a recessed luminaire.

Les luminaires encastrables sont généralement destinés à être encastrés à travers une ouverture pratiquée dans une paroi, par exemple un faux-plafond. Ils comprennent classiquement une collerette, destinée à prendre appui contre une face avant de la paroi, et un ressort de torsion, qui permet d'exercer une force de maintien contre une face arrière de la paroi. Ainsi, le luminaire est maintenu en position à travers la paroi.Recessed luminaires are generally intended to be recessed through an opening in a wall, for example a false ceiling. They conventionally comprise a flange, intended to bear against a front face of the wall, and a torsion spring, which allows to exert a holding force against a rear face of the wall. Thus, the luminaire is held in position through the wall.

Pour faciliter l'opération d'insertion du luminaire dans l'ouverture, il est connu de prévoir un système d'armement du ressort permettant de le retenir dans une position dans laquelle le ressort permet l'insertion du luminaire dans l'ouverture. Ce système est généralement complété de moyens pour libérer automatiquement le ressort une fois que celui-ci a franchi l'ouverture. Le document JP-A-2001043725 montre un luminaire encastrable avec un ressort et une languette flexible.To facilitate the insertion operation of the luminaire in the opening, it is known to provide a spring arming system for holding it in a position in which the spring allows the insertion of the luminaire into the opening. This system is usually supplemented with means for automatically releasing the spring once it has crossed the opening. The document JP-A-2001043725 shows a recessed luminaire with a spring and a flexible tongue.

Ainsi, par exemple, il est connu du document US2011180678 un système comprenant une pièce support présentant deux flancs sur lequel sont ménagées des découpes. Ces découpes reçoivent une pièce de retenue mobile en rotation par rapport à la pièce support. Cette pièce de retenue présente une portion centrale en U et deux extrémités formant levier. Le système comprend également un ressort appuyant contre une pièce d'accroche présentant une découpe formant crochet. Le crochet coopère avec la portion centrale en U pour armer le ressort. Lorsque le système est introduit dans l'ouverture d'une paroi, les extrémités formant levier prennent appui contre la paroi, si bien que la portion centrale en U pivote et libère le crochet, ce qui permet au ressort de se déployer.So, for example, it is known from the document US2011180678 a system comprising a support piece having two flanks on which are formed cutouts. These cutouts receive a retaining piece movable in rotation with respect to the support piece. This retaining piece has a central portion U and two ends forming a lever. The system also includes a spring pressing against an attachment piece having a hook cutout. The hook cooperates with the U-shaped central portion to arm the spring. When the system is introduced into the opening of a wall, the lever ends bear against the wall, so that the U-shaped central portion pivots and releases the hook, allowing the spring to unfold.

Cependant, ce système fait intervenir une pluralité de pièces différentes et des liaisons cinématiques (pivots) entre certaines de ces pièces. Il en résulte un coût de fabrication non négligeable. De plus, certaines pièces nécessitent un usinage pour former les découpes et le crochet.However, this system involves a plurality of different parts and kinematic links (pivots) between some of these parts. This results in a significant manufacturing cost. In addition, some parts require machining to form the cutouts and the hook.

On notera également que l'action d'armement du ressort nécessite plusieurs opérations de la part d'un utilisateur : déplacement du ressort et de la pièce d'accroche en position armée, maintien du ressort et de la pièce dans position armée et, simultanément, rotation de la pièce de retenue pour bloquer le ressort dans la position armée grâce à la portion centrale en U. Ainsi, l'armement du ressort n'est pas « automatique » ; l'utilisateur doit déplacer la pièce de retenue.It should also be noted that the action of arming the spring requires several operations on the part of a user: moving the spring and the attachment piece in the armed position, maintaining the spring and the part in the armed position and simultaneously , rotation of the retaining piece to lock the spring in the armed position through the central U-shaped portion. Thus, the arming of the spring is not "automatic"; the user must move the retainer.

Aussi, la présente invention vise à pallier tout ou partie de ces inconvénients en proposant un luminaire encastrable à coûts de fabrication contenus et pratique d'utilisation.Also, the present invention aims to overcome all or part of these disadvantages by providing a built-in luminaire with contained manufacturing costs and convenient to use.

A cet effet, la présente invention a pour objet un luminaire encastrable, destiné à être inséré à travers une ouverture pratiquée dans une paroi, comprenant un ressort, le ressort présentant une tige d'appui, mobile entre une position armée dans laquelle la tige d'appui permet l'insertion du luminaire dans l'ouverture et une position déployée dans laquelle la tige d'appui s'étend latéralement pour permettre au ressort d'exercer contre une face arrière de la paroi une force permettant de maintenir le luminaire inséré dans l'ouverture, et une portion spiralée enroulée sur le luminaire, destinée à rappeler la tige d'appui en position déployée, tel que
le luminaire comprend une languette flexible, élastiquement déformable, comprenant une extrémité proximale reliée au luminaire, une extrémité distale libre, et, entre l'extrémité proximale et l'extrémité distale libre, une portion intermédiaire d'encliquetage,
l'extrémité distale libre comprenant une surface d'appui destinée à venir en appui contre la paroi lorsque le luminaire est inséré dans l'ouverture pour provoquer une déformation de la languette,
la portion intermédiaire d'encliquetage comprenant une surface de frottement, contre laquelle est destinée à frotter la tige d'appui lorsque la tige d'appui est déplacée jusqu'à la position armée, et une surface de blocage, destinée à bloquer la tige d'appui dans la position armée une fois que la tige d'appui a cessé de frotter contre la surface de frottement,
la surface de frottement présentant un profil conformé pour provoquer la déformation élastique de la languette et/ou de la tige d'appui lorsque la tige d'appui frotte contre la surface de frottement, de manière à armer le ressort sans manipulation de la languette par un utilisateur,
et la languette flexible comprenant une portion de liaison reliant mécaniquement la portion intermédiaire d'encliquetage à l'extrémité distale libre, de sorte que l'insertion du luminaire dans l'ouverture provoque, par appui sur la surface d'appui et flexion de la languette, le déplacement de la surface de blocage hors de la trajectoire décrite par la tige d'appui de la position armée vers la position déployée.For this purpose, the present invention relates to a recessed luminaire, intended to be inserted through an opening in a wall, comprising a spring, the spring having a support rod, movable between an armed position in which the stem of support allows the insertion of the luminaire into the opening and an extended position in which the support rod extends laterally to allow the spring to exert against a rear face of the wall a force to maintain the luminaire inserted in the opening, and a spiral portion wound on the luminaire, for reminding the support rod in the deployed position, such as
the luminaire comprises a flexible tab, elastically deformable, comprising a proximal end connected to the luminaire, a free distal end, and, between the proximal end and the free distal end, an interlocking intermediate portion,
the free distal end comprising a bearing surface intended to bear against the wall when the luminaire is inserted into the opening to cause deformation of the tongue,
the intermediate detent portion comprising a friction surface, against which is intended to rub the support rod when the support rod is moved to the armed position, and a locking surface, for locking the rod support in the armed position once the support rod has stopped rubbing against the friction surface,
the friction surface having a profile shaped to cause the elastic deformation of the tongue and / or the support rod when the support rod rubs against the friction surface, so as to arm the spring without manipulation of the tongue by an user,
and the flexible tongue comprising a connecting portion mechanically connecting the intermediate latching portion to the free distal end, so that the insertion of the luminaire into the opening causes, by pressing on the bearing surface and bending the tongue, the displacement of the blocking surface out of the path described by the support rod of the armed position to the deployed position.

Ainsi, le luminaire selon l'invention offre une solution simple, donc économique, d'armement et déploiement automatiques du ressort, puisque cette solution est basée sur la coopération du ressort avec une pièce unique, à savoir la languette flexible.Thus, the luminaire according to the invention offers a simple solution, thus economic, automatic arming and deployment of the spring, since this solution is based on the cooperation of the spring with a single piece, namely the flexible tongue.

La languette flexible combine de façon avantageuse à la fois les fonctions de détection de la paroi par contact, d'armement et de retenue du ressort par effet cliquet, et de libération de ce dernier par déformation élastique.The flexible tongue advantageously combines both the functions of detection of the wall by contact, arming and retaining the spring ratchet effect, and release of the latter by elastic deformation.

En outre, on notera que l'armement du ressort est plus ergonomique, car réalisé en une seule opération consistant à déplacer la tige d'appui de la position déployée à la position armée. En effet, la déformation élastique de la tige d'appui au contact de la surface de frottement, ou celle de la languette résultant du glissement de la tige d'appui sur la surface de frottement, permet le blocage automatique de la tige d'appui en position armée, sans intervention d'un utilisateur.In addition, it should be noted that the arming of the spring is more ergonomic, since it is carried out in a single operation of moving the support rod from the deployed position to the armed position. Indeed, the elastic deformation of the support rod in contact with the friction surface, or that of the tongue resulting from the sliding of the support rod on the friction surface, allows the automatic locking of the support rod in armed position, without intervention of a user.

Selon un mode de réalisation, le luminaire comprend des moyens de retenue de l'extrémité distale, destinés à solidariser l'extrémité distale libre sur le luminaire après que celui-ci ait été inséré dans l'ouverture.According to one embodiment, the luminaire comprises retaining means of the distal end for securing the free distal end to the luminaire after it has been inserted into the opening.

Ainsi, l'extrémité distale ne revient pas dans sa position initiale. Cela évite que l'extrémité distale entre en contact avec la paroi lors du démontage du luminaire, ce qui pourrait abîmer la paroi ou entraver le démontage du luminaire.Thus, the distal end does not return to its original position. This prevents the distal end from coming into contact with the wall when removing the luminaire, which could damage the wall or interfere with the dismantling of the luminaire.

Avantageusement, la portion intermédiaire d'encliquetage comprend une dent latérale d'encliquetage, formée sur une tranche de la languette, la dent latérale d'encliquetage présentant une face formant une rampe oblique, correspondant à la surface de frottement, et une face formant un cran d'encliquetage, correspondant à la surface de blocage.Advantageously, the intermediate locking portion comprises a lateral detent tooth, formed on one edge of the tongue, the lateral detent tooth having a face forming an oblique ramp, corresponding to the friction surface, and a face forming a snap-in catch, corresponding to the locking surface.

Ainsi, la dent est conçue pour déformer la tige d'appui plutôt que la languette. Cette disposition est particulièrement avantageuse lorsque le luminaire comprend des moyens de retenue de l'extrémité distale. En effet, la languette se déformant peu, l'extrémité distale ne risque pas d'être retenue contre luminaire lors de la manoeuvre de la tige d'appui vers la position armée.Thus, the tooth is designed to deform the support rod rather than the tongue. This arrangement is particularly advantageous when the luminaire comprises retaining means of the distal end. Indeed, the tongue deforming little, the distal end is not likely to be retained against fixture during the maneuvering of the support rod to the armed position.

Selon une forme d'exécution avantageuse, la portion intermédiaire d'encliquetage présente une forme en S.According to an advantageous embodiment, the intermediate snap portion has an S-shape.

Cette caractéristique favorise la déformation de la languette au passage de la tige d'appui et favorise également le retour élastique de la languette dans sa position initiale, donc le blocage automatique de la tige d'appui.This feature promotes the deformation of the tongue to the passage of the support rod and also promotes the elastic return of the tongue in its initial position, so the automatic locking of the support rod.

Selon un mode de réalisation, la tige d'appui comprend une portion distale, une branche latérale reliant la portion spiralée et la portion distale, et une portion de contact, destinée à venir au contact de la surface de frottement puis au contact de la surface de blocage lorsque la tige d'appui est déplacée vers la position armée, la portion de contact étant ménagée sur la branche latérale, à distance de la portion distale.According to one embodiment, the support rod comprises a distal portion, a lateral branch connecting the spiral portion and the distal portion, and a contact portion intended to come into contact with the friction surface and then in contact with the surface. blocking when the support rod is moved to the armed position, the contact portion being formed on the side branch, away from the distal portion.

Ainsi, la portion de contact est située à distance de la branche de liaison et de la portion spiralée, entre celles-ci.Thus, the contact portion is located at a distance from the connecting leg and the spiral portion, therebetween.

La portion distale est donc aisément préhensible par un utilisateur, qui bénéficie en outre d'un effet levier facilitant la manoeuvre de la tige d'appui vers la position armée, contre les forces de frottement générées par le glissement de la portion de contact sur la surface de frottement.The distal portion is easily grippable by a user, who also benefits from a lever effect facilitating the maneuvering of the support rod towards the armed position, against the friction forces generated by the sliding of the contact portion on the friction surface.

La branche de liaison peut en outre accueillir un organe d'amortissement destiné à s'écraser en se comprimant contre la face arrière de la paroi afin d'amortir l'impact de ressort.The connecting branch can also accommodate a damping member intended to crash by compressing against the rear face of the wall to damp the spring impact.

Selon une forme d'exécution avantageuse, la tige d'appui comprend une deuxième branche latérale, reliant la portion spiralée et la portion distale, de sorte que la tige d'appui forme un U, et la languette est agencée pour s'étendre à l'intérieur du U formé par la tige d'appui, entre les branches latérales.According to an advantageous embodiment, the support rod comprises a second lateral branch, connecting the spiral portion and the distal portion, so that the support rod forms a U, and the tongue is arranged to extend to the inside of the U formed by the support rod, between the lateral branches.

Ainsi, l'encombrement est minimal. Cela est particulièrement avantageux lorsque le luminaire comprend un dissipateur thermique présentant une pluralité d'ailettes radiales, car il est aisé d'intercaler la languette et le ressort entre deux ailettes adjacentes du dissipateur thermique, et ce sans affecter sensiblement l'efficacité de la dissipation thermique.Thus, the size is minimal. This is particularly advantageous when the luminaire comprises a heat sink having a plurality of radial fins, because it is easy to interpose the tongue and the spring between two adjacent fins of the heat sink, without significantly affecting the dissipation efficiency. thermal.

Avantageusement, la portion de contact correspond à une portion coudée de la branche latérale.Advantageously, the contact portion corresponds to a bent portion of the lateral branch.

Ainsi, la portion de contact est réalisée sans pièce additionnelle, ce qui limite les coûts de fabrication.Thus, the contact portion is made without additional parts, which limits manufacturing costs.

Selon une possibilité avantageuse, la languette comprend une portion de liaison reliant l'extrémité proximale à la portion intermédiaire d'encliquetage, et la portion de liaison s'étend de façon sensiblement perpendiculaire à la surface de blocage.According to an advantageous possibility, the tongue comprises a connecting portion connecting the proximal end to the intermediate snap portion, and the connecting portion extends substantially perpendicular to the locking surface.

Cela permet un meilleur blocage de la tige d'appui et limite la déformation de la languette lorsque le ressort est armé.This allows a better locking of the support rod and limits the deformation of the tongue when the spring is armed.

Selon un mode de réalisation, la portion de liaison s'étend vers le bas sensiblement en direction d'une paroi périphérique d'appui en formant avec un axe perpendiculaire à la paroi périphérique d'appui un angle inférieur ou égal à 45°, notamment inférieur ou égal à 20°, et de préférence inférieur ou égal à 10°.According to one embodiment, the connecting portion extends downward substantially in the direction of a peripheral bearing wall forming with an axis perpendicular to the peripheral bearing wall an angle less than or equal to 45 °, in particular less than or equal to 20 °, and preferably less than or equal to 10 °.

La faible inclinaison, voire l'inclinaison nulle de la portion de liaison par rapport à la verticale limite le risque que la portion de liaison libère le ressort si elle venait par inadvertance à buter contre la paroi.The low inclination, or even the inclination of the connecting portion relative to the vertical limits the risk that the connecting portion releases the spring if it inadvertently to abut against the wall.

Selon une possibilité avantageuse, le profil de la surface de frottement présente une forme arrondie pour faciliter le déplacement de la tige d'appui sur la surface de frottement.According to an advantageous possibility, the profile of the friction surface has a rounded shape to facilitate the displacement of the support rod on the friction surface.

Cela permet d'introduire une progressivité dans la déformation élastique de la languette et/ou de la tige d'appui lorsque cette dernière glisse sur la surface de frottement jusqu'à la position armée.This allows to introduce a progressiveness in the elastic deformation of the tongue and / or the support rod when the latter slides on the friction surface to the armed position.

La figure 1 montre un luminaire 1 selon un mode de réalisation de l'invention.The figure 1 shows a luminaire 1 according to one embodiment of the invention.

Le luminaire 1 correspond à un luminaire encastrable, destiné à être inséré à travers une ouverture 102 pratiquée dans une paroi 100 qui peut correspondre à un faux-plafond. Le luminaire 1 peut correspondre à un spot lumineux.The luminaire 1 corresponds to a recessed luminaire, intended to be inserted through an opening 102 made in a wall 100 which can match a false ceiling. The luminaire 1 can correspond to a luminous spot.

Le luminaire 1 peut comprendre un boîtier 2, à l'intérieur duquel peut être agencée une source lumineuse. Le boîtier 2 délimite une ouverture 3 visible sur la figure 6, par exemple sensiblement circulaire, permettant à la lumière émise par la source lumineuse de sortir du boîtier 2. A l'arrière du boîtier 2 peut être prévu un dissipateur 4 thermique. Le dissipateur 4 thermique peut comprendre une pluralité d'ailettes 6 s'étendant de façon sensiblement radiale.The luminaire 1 may comprise a housing 2 inside which a light source may be arranged. The housing 2 defines an opening 3 visible on the figure 6 , for example substantially circular, allowing the light emitted by the light source to exit the housing 2. At the rear of the housing 2 may be provided a heat sink 4. The heat sink 4 may comprise a plurality of fins 6 extending substantially radially.

Le luminaire 1 peut comprendre une paroi 8 périphérique d'appui destinée à venir en appui contre une face 104 avant de la paroi 100. La paroi 8 périphérique d'appui peut former collerette autour de l'ouverture du boîtier 2. Elle peut être sensiblement circulaire, comme cela est illustré sur les figures 1 à 8.The luminaire 1 may comprise a peripheral support wall 8 intended to bear against a front face 104 of the wall 100. The peripheral support wall 8 may form a collar around the opening of the housing 2. It may be substantially circular, as illustrated in the Figures 1 to 8 .

Le luminaire 1 peut éventuellement comprendre une paroi 10 de positionnement destinée à venir en appui contre une face 106 intérieure de l'ouverture 102 pratiquée dans la paroi 100. La paroi 10 de positionnement peut être sensiblement cylindrique, comme c'est le cas sur les figures 1 à 8.The luminaire 1 may optionally comprise a positioning wall 10 intended to bear against an inner face 106 of the opening 102 formed in the wall 100. The positioning wall 10 may be substantially cylindrical, as is the case on the Figures 1 to 8 .

Le luminaire 1 comprend un ressort 12. Ce ressort 12 comprend une tige 14 d'appui et une portion 16 spiralée.The luminaire 1 comprises a spring 12. This spring 12 comprises a support rod 14 and a spiral portion 16.

La tige 14 d'appui est mobile entre une position armée, visible sur les figures 1, 5 et 6, dans laquelle la tige 14 d'appui s'étend de façon sensiblement perpendiculaire à la paroi 8 périphérique d'appui pour permettre l'insertion du luminaire 1 dans l'ouverture 102, et une position déployée, visible sur les figures 3 et 8, dans laquelle la tige 14 d'appui s'étend latéralement, au-dessus de la paroi 8 périphérique d'appui, pour permettre au ressort 12 d'exercer contre une face 108 arrière de la paroi de faux-plafond une force permettant de maintenir le luminaire 1 inséré dans l'ouverture 102.The support rod 14 is movable between an armed position, visible on the figures 1 , 5 and 6 , in which the support rod 14 extends substantially perpendicularly to the peripheral wall 8 for supporting the insertion of the luminaire 1 into the opening 102, and an extended position, visible on the Figures 3 and 8 , in which the support rod 14 extends laterally, above the peripheral wall 8, to allow the spring 12 to exert against a rear face 108 of the false ceiling wall a force allowing hold the luminaire 1 inserted in the opening 102.

La portion 16 spiralée est enroulée sur le luminaire 1 et destinée à rappeler la tige 14 d'appui en position déployée.The spiral portion 16 is wound on the luminaire 1 and intended to return the support rod 14 in the deployed position.

Le luminaire 1 peut bien entendu comprendre plusieurs ressorts 12, par exemple deux ressorts 12, comme sur les figures 1 à 8. Ces deux ressorts 12 peuvent être diamétralement opposés.The luminaire 1 can of course comprise several springs 12, for example two springs 12, as on the Figures 1 to 8 . These two springs 12 can be diametrically opposed.

Selon l'invention, le luminaire 1 comprend une languette 18 flexible destinée à coopérer avec le ressort 12. Il est important de noter que la languette 18 flexible est élastiquement déformable. Par languette 18 flexible élastiquement déformable on entend languette 18 apte à se déformer sous l'effet d'une contrainte extérieure qui lui est appliquée puis à revenir dans sa position initiale en l'absence d'une telle contrainte. La languette 18 peut correspondre, par exemple, à une lame métallique. Le luminaire 1 peut comprendre une languette 18 par ressort 12.According to the invention, the luminaire 1 comprises a flexible tongue 18 intended to cooperate with the spring 12. It is important to note that the flexible tongue 18 is elastically deformable. By flexible tongue 18 elastically deformable means tongue 18 able to deform under the effect of an external stress applied to it and then return to its initial position in the absence of such a constraint. The tongue 18 may correspond, for example, to a metal blade. The luminaire 1 may comprise a tongue 18 by spring 12.

Comme on peut le voir sur les figures, notamment sur la figure 10, la languette 18 comprend une extrémité 20 proximale, une extrémité 22 distale libre et, entre l'extrémité 20 proximale et l'extrémité 22 distale libre, une portion intermédiaire d'encliquetage.As can be seen in the figures, especially on the figure 10 the tongue 18 comprises a proximal end, a free distal end 22 and, between the proximal end and the free distal end 22, an interlocking intermediate portion.

L'extrémité 20 proximale peut être avantageusement solidaire du luminaire 1. Il est notamment possible de prévoir des moyens de fixation, comme des vis 24, pour fixer solidement l'extrémité 20 proximale sur le luminaire 1.The proximal end may advantageously be integral with the luminaire 1. It is in particular possible to provide fastening means, such as screws 24, for securely fixing the proximal end to the luminaire 1.

Ainsi, la languette 18 est dépourvue d'articulation sur le luminaire 1, comme un axe de liaison pivot ou un guidage en translation. Seule la déformation élastique de la languette 18, et le cas échéant de la tige 14 d'appui, permet un armement et un désarmement automatiques du ressort 12.Thus, the tongue 18 is devoid of articulation on the luminaire 1, such as a pivot connection axis or a translation guide. Only the elastic deformation of the tongue 18, and if necessary of the support rod 14, allows automatic arming and disarming of the spring 12.

L'extrémité 20 proximale peut comprendre le cas échéant deux alésages 26 destinés chacun à recevoir une vis.The proximal end may include, where appropriate, two bores 26 each intended to receive a screw.

Ainsi, le luminaire 1 comprend deux points de fixation de la languette 18 pour éviter qu'elle pivote en subissant la contrainte du ressort 12.Thus, the luminaire 1 comprises two fixing points of the tongue 18 to prevent it from pivoting under the stress of the spring 12.

L'extrémité 22 distale libre comprend une surface 28 d'appui destinée à venir en appui contre la paroi 100 de faux-plafond lorsque le luminaire 1 est inséré dans l'ouverture de la paroi 100 de faux-plafond.The free distal end 22 comprises a bearing surface 28 intended to bear against the wall 100 of the false ceiling when the luminaire 1 is inserted into the opening of the wall 100 of false ceiling.

L'extrémité 22 distale libre peut s'étendre au-dessus de la paroi 8 périphérique d'appui, en regard et à distance de celle-ci.The free distal end 22 may extend above the peripheral wall 8, facing and at a distance from it.

Selon une caractéristique avantageuse, la portion intermédiaire d'encliquetage peut présenter une forme de S, ce S étant conçu pour favoriser la déformation élastique de la languette 18. Cela apporte une plus grande ergonomie d'utilisation.According to an advantageous characteristic, the intermediate snap portion may have a shape of S, S being designed to promote the elastic deformation of the tongue 18. This provides greater ergonomics of use.

La portion intermédiaire d'encliquetage comprend une surface de frottement contre laquelle est destinée à frotter la tige 14 d'appui lorsque la tige 14 d'appui est déplacée jusqu'à la position armée.The intermediate snap portion comprises a friction surface against which is intended to rub the support rod 14 when the support rod 14 is moved to the armed position.

La surface de frottement présente un profil conformé pour provoquer la déformation élastique de la languette 18 et/ou de la tige 14 d'appui, lorsque la tige 14 d'appui frotte contre la surface de frottement.The friction surface has a profile shaped to cause the elastic deformation of the tongue 18 and / or the support rod 14, when the support rod 14 rubs against the friction surface.

La portion intermédiaire d'encliquetage comprend aussi une surface de blocage destinée à bloquer la tige 14 d'appui dans la position armée.The intermediate snap portion also comprises a locking surface for locking the support rod 14 in the armed position.

La surface de frottement est adjacente à la surface de frottement. Elle est agencée dans la continuité de la surface de frottement, derrière cette dernière.The friction surface is adjacent to the friction surface. It is arranged in the continuity of the friction surface, behind the latter.

La surface de blocage peut être séparée de la surface de frottement par une arête saillante ou une portion arrondie.The blocking surface may be separated from the friction surface by a projecting edge or a rounded portion.

La portion intermédiaire d'encliquetage peut comprendre une dent 30 latérale d'encliquetage, formée sur une tranche de la languette 18. Cette dent 30 présente une face 32 latérale, une face 34 formant une rampe oblique et une face 36 formant un cran d'encliquetage.The intermediate detent portion may comprise a lateral latching tooth formed on a slice of the tongue 18. This tooth 30 has a lateral face 32, a face 34 forming an oblique ramp and a face 36 forming a notch. snap.

La face 36 formant cran d'encliquetage peut correspondre à la surface de blocage.The face 36 forming latching notch may correspond to the locking surface.

La surface de blocage peut aussi correspondre à une face 38 de l'un des renfoncements du S formé par la portion intermédiaire d'encliquetage.The locking surface may also correspond to a face 38 of one of the recesses of the S formed by the intermediate snap portion.

Selon un mode de réalisation, la face 32 latérale peut correspondre à la surface de frottement. Ainsi, la languette 18 se déforme en fléchissant vers le bas lorsque la tige 14 d'appui glisse sur la surface de frottement. Par bas ou haut, il faut entendre vers l'avant ou l'arrière du luminaire, c'est-à-dire vers le côté du luminaire par lequel est destiné à sortir la lumière ou le côté opposé.According to one embodiment, the lateral face 32 may correspond to the friction surface. Thus, the tongue 18 is deformed by bending downwards when the support rod 14 slides on the friction surface. Low or high, it is necessary to hear towards the front or the back of the luminaire, that is to say towards the side of the luminaire by which is intended to leave the light or the opposite side.

Il est également possible qu'une face 39 avant du S formé par la portion intermédiaire d'encliquetage corresponde à la surface de frottement.It is also possible that a front face 39 of the S formed by the intermediate snap portion corresponds to the friction surface.

Selon une autre possibilité, la face 34 formant rampe oblique peut correspondre à la surface de frottement. Ainsi, c'est essentiellement la tige 14 d'appui qui se déforme au contact de la surface de frottement. La languette 18 se déforme peu au passage de la tige 14 d'appui, ce qui est avantageux lorsque le luminaire 1 comprend des moyens de retenue de l'extrémité 22 distale, comme décrit ci-après.According to another possibility, the face 34 forming oblique ramp may correspond to the friction surface. Thus, it is essentially the support rod 14 that deforms in contact with the friction surface. The tongue 18 is slightly deformed in the passage of the support rod 14, which is advantageous when the luminaire 1 comprises retaining means of the distal end 22, as described below.

La portion intermédiaire d'encliquetage peut comprendre plusieurs dents 30 latérales d'encliquetage, par exemple deux dents 30 opposées comme sur la figure 10. Les faces 34 formant rampes obliques créent un élargissement de la languette 18 en direction de l'extrémité 20 proximale. Cette configuration permet par exemple de coopérer avec une tige 14 d'appui en U présentant un rétrécissement intermédiaire, comme cela sera décrit ci-après.The intermediate snap portion may comprise a plurality of lateral ratchet teeth, for example two opposing teeth as shown in FIG. figure 10 . The faces 34 forming oblique ramps create an enlargement of the tongue 18 towards the proximal end. This configuration makes it possible, for example, to cooperate with a U-shaped support rod 14 having an intermediate narrowing, as will be described hereinafter.

La languette 18 flexible comprend par ailleurs une portion 40 de liaison reliant mécaniquement la portion intermédiaire d'encliquetage à l'extrémité 22 distale libre.The flexible tongue 18 further comprises a connecting portion 40 mechanically connecting the intermediate snap portion to the free distal end 22.

La portion 40 de liaison peut avantageusement s'étendre vers le bas sensiblement en direction de la paroi 8 périphérique d'appui en formant avec un axe perpendiculaire à la paroi 8 périphérique d'appui un angle inférieur ou égal à 45°, notamment inférieur ou égal à 20°, et de préférence inférieur ou égal à 10°. La faible inclinaison, voire l'inclinaison nulle de la portion 40 de liaison par rapport à la verticale limite le risque que la portion 40 de liaison libère le ressort 12 si elle venait par inadvertance à buter contre la paroi 100.The connecting portion 40 may advantageously extend downward substantially in the direction of the peripheral support wall 8 forming, with an axis perpendicular to the peripheral wall 8, an angle of less than or equal to 45 °, especially less than or equal to 20 °, and preferably less than or equal to 10 °. The small inclination, or even the inclination of the connecting portion 40 with respect to the vertical limit the risk that the connecting portion 40 releases the spring 12 if it inadvertently to abut against the wall 100.

L'extrémité 20 proximale, la portion intermédiaire d'encliquetage et la portion 40 de liaison reliant la portion intermédiaire d'encliquetage à l'extrémité 22 distale peuvent avantageusement s'étendre à l'intérieur d'un volume, par exemple cylindrique, délimité par la paroi 10 de positionnement, tandis que l'extrémité 22 distale libre s'étend en-dehors de ce cylindre. Autrement dit, ne s'étendent pas au-dessus de la paroi 8 périphérique d'appui, ce qui limite le risque de contact entre la paroi 100 dans laquelle est insérée le luminaire 1 et une partie de la languette 18 autre que l'extrémité 22 distale libre.The proximal end, the intermediate snap portion and the connecting portion 40 connecting the intermediate snap portion to the distal end 22 may advantageously extend within a volume, for example cylindrical, delimited by the positioning wall 10, while the free distal end 22 extends outside this cylinder. In other words, do not extend above the wall 8 peripheral support, which limits the risk of contact between the wall 100 which is inserted in the luminaire 1 and a portion of the tongue 18 other than the end 22 distal free.

La languette 18 peut comprendre une autre portion 42 de liaison reliant l'extrémité 20 proximale à la portion intermédiaire d'encliquetage, cette portion 42 de liaison s'étendant de façon sensiblement perpendiculaire à la surface de blocage pour mieux retenir la tige 14 d'appui dans la position armée.The tongue 18 may comprise another connecting portion 42 connecting the proximal end to the intermediate snap portion, this connecting portion 42 extending substantially perpendicularly to the blocking surface to better retain the rod 14. support in the armed position.

De manière avantageuse, le luminaire 1 peut comprendre des moyens de retenue destinés à solidariser l'extrémité 22 distale libre sur le luminaire 1 après que celui-ci ait été inséré dans l'ouverture de la paroi de faux-plafond, comme cela est illustré sur la figure 2. Les moyens de retenue peuvent comprendre un organe d'accroche et un trou 44 destiné à recevoir l'organe d'accroche lorsque le luminaire 1 est inséré dans l'ouverture. L'organe d'accroche peut correspondre à un ergot 46 s'étendant depuis le luminaire 1. Le trou 44 peut être ménagé dans l'extrémité 22 distale libre.Advantageously, the luminaire 1 may comprise retaining means for securing the free distal end 22 to the luminaire 1 after it has been inserted into the opening of the false ceiling wall, as illustrated. on the figure 2 . The retaining means may comprise a fastener member and a hole 44 for receiving the fastener member when the luminaire 1 is inserted into the opening. The attachment member may correspond to a lug 46 extending from the luminaire 1. The hole 44 may be formed in the free distal end 22.

Comme on peut le voir sur les figures, notamment sur la figure 9, la tige 14 d'appui peut comprendre une portion 48 distale, une branche 50 latérale reliant la portion 16 spiralée et la portion 48 distale, et une portion 52 de contact, destinée à venir au contact de la surface de frottement puis au contact de la surface de blocage lorsque la tige 14 d'appui est déplacée vers la position armée. La portion 52 de contact est ménagée sur la branche 50 latérale, à distance de la portion 48 distale, pour créer un bras de levier facilitant la manoeuvre d'armement du ressort 12. Cela offre également la possibilité d'adjoindre à la portion 48 distale un organe 54 d'amortissement, par exemple en matériau élastomère et de forme tubulaire, destiné à préserver la paroi dans laquelle est inséré le luminaire 1.As can be seen in the figures, especially on the figure 9 , the support rod 14 may comprise a distal portion 48, a lateral branch 50 connecting the spiral portion 16 and the distal portion 48, and a contact portion 52 intended to come into contact with the friction surface and then contact of the blocking surface when the support rod 14 is moved to the armed position. The portion 52 of contact is formed on the lateral branch 50, away from the distal portion 48, to create a lever arm facilitating the arming maneuver of the spring 12. This also offers the possibility of adding to the portion 48 distal a damping member 54, for example made of elastomeric material and of tubular shape, intended to preserve the wall in which the luminaire 1 is inserted.

Plus particulièrement, la portion 52 de contact peut correspondre à une portion coudée de la branche 50 latérale. Autrement dit, la coopération de la tige 14 d'appui et de la languette 18 est réalisée sans pièce additionnelle.More particularly, the contact portion 52 may correspond to a bent portion of the lateral branch 50. In other words, the cooperation of the support rod 14 and the tongue 18 is made without additional parts.

Pour une meilleure résistance du ressort 12, la tige 14 d'appui peut comprendre une deuxième branche 50 latérale, reliant la portion 16 spiralée et la portion 48 distale, de sorte que la tige 14 d'appui forme un U.For better resistance of the spring 12, the support rod 14 may comprise a second lateral branch 50, connecting the spiral portion 16 and the distal portion 48, so that the support rod 14 forms a U.

La languette 18 est avantageusement agencée pour s'étendre à l'intérieur de ce U, c'est-à-dire entre les branches 50 latérales. Ainsi, l'encombrement est minimal, si bien qu'il est aisé d'intercaler la languette 18 et le ressort 12 entre deux ailettes du dissipateur thermique sans affecter sensiblement l'efficacité de la dissipation thermique.The tongue 18 is advantageously arranged to extend inside this U, that is to say between the lateral branches 50. Thus, the space requirement is minimal, so that it is easy to insert the tongue 18 and the spring 12 between two fins of the heat sink without substantially affecting the efficiency of the heat dissipation.

La deuxième branche 50 latérale peut elle aussi comprendre une portion 52 de contact agencée à distance de la portion 48 distale, pour équilibrer les efforts exercés sur la languette 18. La portion 52 de contact peut également être coudée.The second lateral branch 50 may also include a portion 52 of contact arranged at a distance from the distal portion 48, to balance the forces exerted on the tongue 18. The portion 52 of contact can also be bent.

Avantageusement, les deux portions 52 de contact présentent une forme de U orienté vers l'intérieur du U formé par la tige 14 d'appui, et sont agencées en regard l'une de l'autre pour former un rétrécissement intermédiaire.Advantageously, the two portions 52 of contact have an U-shaped face oriented towards the inside of the U formed by the support rod 14, and are arranged facing one another to form an intermediate narrowing.

Le fonctionnement du luminaire 1 est décrit ci-après, partant d'une situation initiale dans laquelle les ressorts 12 sont déployés, comme cela est représenté sur la figure 3.The operation of the luminaire 1 is described below, starting from an initial situation in which the springs 12 are deployed, as shown in FIG. figure 3 .

Un utilisateur arme les ressorts 12 en un seul mouvement, consistant à déplacer les tiges 14 d'appui vers la position armée, et au cours duquel l'utilisateur n'a pas besoin de manipuler les languettes 18 (figure 4).A user arms the springs 12 in a single movement, consisting of moving the support rods 14 towards the armed position, and during which the user does not need to manipulate the tongues 18 ( figure 4 ).

Au cours de ce mouvement, les tiges 14 d'appui rencontrent les surfaces de frottement, sur lesquelles elles glissent. Le profil des surfaces de frottement provoque le fléchissement des languettes 18 vers le bas pour laisser passer la tige 14 d'appui, et/ou une déformation élastique des tiges 14 d'appui elles-mêmes.During this movement, the support rods 14 meet the friction surfaces on which they slide. The profile of the friction surfaces causes the tongues 18 to bend down to leave passing the support rod 14, and / or an elastic deformation of the support rods 14 themselves.

La déformation élastique des languettes et/ou des tiges 14 d'appui permet l'encliquetage, donc l'armement automatique des ressorts 12 lorsque les languettes et/ou les tiges 14 d'appui reprennent leur forme initiale (figure 5).The elastic deformation of the tongues and / or support rods 14 allows the latching, thus the automatic arming of the springs 12 when the tongues and / or the support rods 14 resume their original shape ( figure 5 ).

Les tiges 14 d'appui sont dans la position armée et bloquées dans cette position par les surfaces de blocage.The support rods 14 are in the armed position and locked in this position by the locking surfaces.

Lorsque le luminaire 1 est introduit dans l'ouverture pratiquée dans la paroi (figure 6), la surface 28 d'appui de l'extrémité 22 distale libre vient au contact de la face avant de la paroi, ce qui provoque le fléchissement vers le bas de la languette 18, donc le déplacement de la surface de blocage hors de la trajectoire des tiges 14 d'appui (figures 2 et 7).When the luminaire 1 is inserted into the opening in the wall ( figure 6 ), the bearing surface 28 of the free distal end 22 comes into contact with the front face of the wall, which causes the tongue 18 to bend downwards, thus displacing the locking surface out of the trajectory of the support rods 14 ( figures 2 and 7 ).

Ces dernières, rappelées par les portions spiralées correspondantes, se déploient donc automatiquement jusqu'à appuyer contre la face arrière de la paroi (figure 8).The latter, recalled by the corresponding spiral portions, therefore deploy automatically until pressing against the rear face of the wall ( figure 8 ).

Le cas échéant, au moment de l'insertion du luminaire 1 dans la paroi, le trou 44 de l'extrémité 22 distale libre engage l'ergot 46 du luminaire 1 pour retenir l'extrémité 22 distale libre (figure 2), autrement dit pour empêcher la languette 18 de reprendre sa forme initiale. Ainsi, l'extrémité 22 distale libre n'entravera pas un éventuel démontage du luminaire 1.If necessary, at the time of insertion of the luminaire 1 into the wall, the hole 44 of the free distal end 22 engages the lug 46 of the luminaire 1 to retain the free distal end 22 ( figure 2 ), in other words to prevent the tongue 18 from returning to its original shape. Thus, the free distal end 22 will not hinder any dismantling of the luminaire 1.

Claims (10)

  1. Recessable luminaire (1), intended to be recessed through an opening in a wall, comprising a spring (12), the spring (12) having a supporting rod (14) movable between an armed position in which the supporting rod (14) allows the insertion of the luminaire (1) in the opening and a deployed position in which the supporting rod (14) extends laterally to allow the spring (12) to apply against a side rear wall a force holding the luminaire (1) inserted into the opening, and a portion (16) wound spirally on the luminaire (1), for biaising the supporting rod (14) in the deployed position,
    characterized in that the luminaire (1) comprises a flexible tongue (18), elastically deformable, having a proximal end (20) connected to the luminaire (1), a distal free end (22), and, between the proximal end (20) and the distal free end (22), an intermediate click-stop portion,
    the distal free end (22) comprising a supporting surface (28) intended to come into abutment against the wall when the luminaire (1) is inserted into the opening to cause the deformation of the tongue (18),
    the intermediate click-stop portion comprising a friction surface, against which is intended to rub the supporting rod (14) when the supporting rod (14) is moved to the armed position, and a locking surface, for locking the supporting rod (14) in the armed position once the supporting rod (14) stopped rubbing against the friction surface,
    the friction surface having a profile configured to cause the elastic deformation of the tongue (18) and/or the rod (14) when the supporting rod (14) rubs against the friction surface, so as to arm the spring (12) without manipulation of the tongue (18) by a user,
    and the flexible tongue (18) comprising a connecting portion (40) connecting mechanically the intermediate click-stop portion to the distal free end (22), so that the insertion of the luminaire (1) in the opening causes, by supporting on the supporting surface (28) and bending the tongue (18), the displacement of the locking surface out of the path described by the supporting rod (14) from the armed position to the deployed position.
  2. Luminaire (1) according to claim 1, characterized in that the luminaire (1) comprises retaining means of the distal end (22), for securing the free distal end (22) on the luminaire (1) after the latter has been inserted into the opening.
  3. Luminaire (1) according to claim 2, characterized in that the click-stop intermediate portion comprises a click-stop lateral tooth (30), formed on an edge of the tongue (18), the click-stop lateral tooth (30) having a face (34) forming an oblique ramp, corresponding to the friction surface, and a face (36) forming a click-stop notch, corresponding to the locking surface.
  4. Luminaire (1) according to one of claims 1 to 3, characterized in that the intermediate click-stop portion is S-shaped.
  5. Luminaire (1) according to one of claims 1 to 4, characterized in that the supporting rod (14) comprises a distal portion (48), a lateral branch (50) connecting the spiral portion (16) and the distal (48) portion, and a contact portion (52), intended to come into contact with the friction surface and into contact with the locking surface when the supporting rod (14) is moved to the armed position, the contact portion (52) being provided on the lateral branch (50, distally from the distal portion (48).
  6. Luminaire (1) according to claim 5, characterized in that the supporting rod (14) comprises a second lateral branch (50), connecting the spiral portion (16) and the distal portion (48), so that the supporting rod (14) is U-shaped, and in that the tongue (18) is arranged to extend inside the U formed by the supporting rod (14), between the lateral branches (50).
  7. Luminaire (1) according to claim 5 or 6, characterized in that the contact portion (52) corresponds to a bent portion of the lateral branch (50).
  8. Luminaire (1) according to one of claims 1 to 7, characterized in that the tongue (18) comprises a connecting portion (42) connecting the proximal end (20) to the click-stop intermediate portion, and in that the connecting portion (42) extends substantially perpendicularly to the locking surface.
  9. Luminaire according to one of claims 1 to 8, characterized in that the connecting portion (40)extends substantially downwardly in the direction of the peripheral supporting wall (8) by forming with an perpendicularly axis to the peripheral supporting wall (8) an angle of 45° or less, in particular of 20° or less, and preferentially of 10° or less.
  10. Luminaire (1) according to one of claims 1 to 9, characterized in that the profile of the friction surface has a rounded shape to facilitate movement of the supporting rod (14) on the friction surface.
