Abstract

The device (1) has a set of branches (2) to cap a lamp, where the device is formed as a single piece by flat molding. Each branch in the set of branches is articulated with respect to another branch in the set of branches, so as to rotatably move from a pre-capping position to a lamp capping position. Hinges (10) bring the branches, which are beyond the capping position, toward the capping position. An independent claim is also included for a method for assembling a ceiling lamp capping device.

Description

L'invention concerne le coiffage de lampe pour plafond et en particulier un dispositif de coiffage à branches pour lampe de type spot de plafond, apte à être monté dans un plafond.The invention relates to the capping of ceiling lamp and in particular a branch capping device for ceilings ceiling type lamp, able to be mounted in a ceiling.

On connaît des dispositifs de coiffage de lampe comprenant des branches écartées les unes des autres, définissant une enveloppe de coiffage à forme générale de cloche, apte à loger la lampe et à isoler thermiquement la lampe d'une couche de matière isolante de type bande ou nappe disposée dans le plenum ou l'épaisseur du plafond.Lamp hacking devices are known comprising branches spaced apart from one another, defining a generally bell-shaped hairstyle for accommodating the lamp and thermally insulating the lamp with a layer of insulating material of the strip type or tablecloth arranged in the plenum or the thickness of the ceiling.

Ces dispositifs de coiffage, définissant une enveloppe de coiffage à forme générale de cloche, sont généralement obtenus par moulage.These styling devices, defining a styling envelope with a generally bell-shaped shape, are generally obtained by molding.

Il existe un besoin pour une fabrication, un stockage et/ou une installation plus simple.There is a need for simpler manufacturing, storage and / or installation.

Il est proposé un dispositif de coiffage de lampe destiné à être installé dans un plafond, comprenant une pluralité de branches pour coiffer une lampe. Ce dispositif est agencé de sorte qu'au moins une branche de cette pluralité de branches soit articulée par rapport à au moins une autre branche de cette pluralité de branches, de façon à pouvoir passer par un mouvement de rotation d'une position de pré-coiffage à une position de coiffage de lampe.There is provided a lamp capping device for installation in a ceiling, comprising a plurality of branches for capping a lamp. This device is arranged so that at least one branch of this plurality of branches is articulated with respect to at least one other branch of this plurality of branches, so as to be able to go through a rotational movement of a pre-positioned position. styling at a lamp styling position.

Ainsi, cette au moins une branche, dite branche articulée, est susceptible d'avoir différentes orientations. A une position de coiffage de lampe correspondant à une situation dans laquelle le dispositif de coiffage est installé dans le plafond, l'ensemble des branches dans la position de coiffage définissant une enveloppe de coiffage, s'ajoute(nt) une ou plusieurs positions des pré-coiffage, ce qui peut permettre de faciliter la fabrication, le stockage et/ou l'installation du dispositif de coiffage.Thus, this at least one branch, called articulated branch, is likely to have different orientations. In a lamp-styling position corresponding to a situation in which the styling device is installed in the ceiling, the set of branches in the styling position defining a styling envelope, is added to one or more positions of the pre-styling, which can facilitate the manufacture, storage and / or installation of the styling device.

Cette au moins une branche, dite branche articulée, peut être articulée directement à au moins une autre branche, ou indirectement. Dans le premier cas, on peut par exemple prévoir un dispositif de coiffage dont les branches ont des extrémités agencées de façon à autoriser des mouvements de rotation relatifs des branches les unes par rapport aux autres. Dans le deuxième cas, on pourra par exemple prévoir un élément support, par exemple à forme générale d'assiette ou de coupelle renversée, auquel au moins une branche est articulée.This at least one branch, said articulated branch, can be articulated directly to at least one other branch, or indirectly. In the first case, one can for example provide a styling device whose branches have ends arranged to allow relative rotational movements of the branches relative to each other. In the second case, it may for example provide a support member, for example in the general shape of plate or cup reversed, which at least one branch is articulated.

Le dispositif de coiffage peut être moulé d'une seule pièce.The styling device can be molded in one piece.

Le dispositif de coiffage peut être monté, par exemple encastré, dans un système de faux plafond de type à dalles ou à plaques, et/ou ossatures (suspendu ou fixé par un autre moyen), mais l'invention n'est pas limitée à une application aux systèmes de faux plafond. On pourrait par exemple prévoir le montage du dispositif de coiffage dans un plafond classique, par exemple à poutres, dans l'épaisseur du plafond. Le plafond comporte une couche basse, par exemple un ensemble de dalles reposant sur une ossature support ou de Placoplatre, cette couche basse étant disposée de façon à aménager un espace interne susceptible de recevoir de la matière isolante sous forme de nappe, et/ou autre.The styling device can be mounted, for example recessed, in a slab or plate type false ceiling system and / or framework (suspended or otherwise fixed), but the invention is not limited to an application to false ceiling systems. One could for example provide the mounting of the styling device in a conventional ceiling, for example beams, in the thickness of the ceiling. The ceiling comprises a low layer, for example a set of slabs resting on a support frame or Placoplatre, this lower layer being arranged so as to provide an internal space capable of receiving insulating material in the form of a sheet, and / or other .

L'invention n'est par ailleurs en rien limitée par le type de faux plafond dans lequel le dispositif de coiffage peut être installé.The invention is also in no way limited by the type of false ceiling in which the styling device can be installed.

L'invention pourra trouver notamment des applications dans les plafonds et faux plafonds d'usine, de bureaux, d'habitation, de parties communes d'immeubles ou autres.The invention may find particular applications in the ceilings and false ceilings of factory, offices, housing, common areas of buildings or other.

La lampe est montée, par exemple encastrée ou non, dans le plafond.The lamp is mounted, for example recessed or not, in the ceiling.

Le dispositif de coiffage peut être monté encastré dans le plafond en l'enfonçant (depuis le dessous vers le dessus), dans un orifice de la couche basse du plafond correspondant à un emplacement de lampe. Le dispositif de coiffage peut alternativement être posé par en-dessus sur la couche basse du plafond. Dans le premier cas, il peut être intéressant de prévoir aux extrémités des branches des plaquettes externes destinées à venir s'enfoncer dans l'épaisseur du rebord de l'orifice de la couche basse du plafond.The styling device can be recessed into the ceiling by pushing it (from below to the top) into a hole in the lower layer of the ceiling corresponding to a lamp location. The styling device can alternatively be placed from above on the lower layer of the ceiling. In the first case, it may be advantageous to provide at the ends of the branches outer plates intended to be sinking into the thickness of the rim of the orifice of the lower layer of the ceiling.

Le dispositif de coiffage peut éventuellement être monté sur une plaque apte à supporter la lampe coiffée et à reposer sur un système de plafond de façon à transmettre sa propre charge et la charge de la lampe à une structure porteuse du système de plafond. Une telle plaque est décrite dans la demande de brevet FR1156161 . Dans ce cas, les branches viennent simplement reposer en butée contre le rebord de l'orifice de la plaque correspondant à l'emplacement de la lampe.The styling device may optionally be mounted on a plate adapted to support the capped lamp and to rest on a ceiling system so as to transmit its own load and the load of the lamp to a supporting structure of the ceiling system. Such a plate is described in the patent application FR1156161 . In this case, the branches simply abut against the rim of the hole of the plate corresponding to the location of the lamp.

Le mouvement de rotation de la branche articulée peut être effectué par rapport à un axe correspondant à cette branche et perpendiculaire à une direction longitudinale de symétrie d'une enveloppe de coiffage définie par la pluralité de branches lorsque ces branches sont en position de coiffage. Ainsi la position de coiffage et la ou les positions de pré-coiffage peuvent correspondre à des valeurs angulaires respectives entre cette direction longitudinale et une direction tangente de la branche articulée.The rotational movement of the articulated branch may be effected with respect to an axis corresponding to this branch and perpendicular to a longitudinal direction of symmetry of a styling casing defined by the plurality of branches when these branches are in the styling position. Thus the capping position and the pre-styling position or positions can correspond to respective angular values between this longitudinal direction and a tangent direction of the articulated branch.

Par exemple, le mouvement de rotation entre la position de pré-coiffage et la position de coiffage peut correspondre à une augmentation en valeur absolue de cet angle. Dit autrement, les branches en position de pré-coiffage sont davantage rapprochées les unes des autres qu'en position de coiffage. Ainsi, lorsque les branches sont en position de pré-coiffage, le dispositif de coiffage a une section plus faible que lorsque les branches sont en position de coiffage, ce qui peut par exemple permettre d'introduire relativement facilement ce dispositif de coiffage dans un orifice d'une couche basse du plafond correspondant à un emplacement de lampe. Le dispositif de coiffage est ainsi agencé de façon à permettre une installation relativement aisée.For example, the rotational movement between the pre-styling position and the styling position may correspond to an increase in absolute value of this angle. In other words, the branches in the pre-styling position are closer together than in the styling position. Thus, when the branches are in the pre-styling position, the styling device has a smaller section than when the branches are in the styling position, which may, for example, make it possible to introduce this styling device relatively easily into an orifice a low layer of the ceiling corresponding to a lamp location. The styling device is thus arranged to allow a relatively easy installation.

On peut par ailleurs prévoir que le mouvement de rotation permettant de passer de la position de pré-coiffage à la position de coiffage corresponde à une réduction de la valeur absolue de l'angle entre la direction longitudinale du dispositif de coiffage et une direction tangente de la branche articulée. Dit autrement, lorsque les branches sont en position de pré-coiffage, elles sont davantage écartées les unes des autres qu'en position de coiffage. On passe de la position de pré-coiffage à la position de coiffage en ramenant les branches les unes vers les autres, par exemple selon un mouvement comparable à un mouvement de fermeture de parapluie.It is also possible to provide that the rotational movement making it possible to pass from the pre-styling position to the styling position corresponds to a reduction in the absolute value of the angle between the longitudinal direction of the styling device and a tangent direction of the articulated branch. In other words, when the branches are in the pre-styling position, they are further apart from one another than in the styling position. It goes from the pre-styling position to the styling position by bringing the branches towards each other, for example in a movement comparable to an umbrella closing movement.

Par exemple, en position de pré-coiffage, chaque branche peut former avec la direction longitudinale un angle compris entre 80 et 100 degrés, par exemple proche de 90 degrés. Dit autrement, lorsque toutes les branches sont en position de pré-coiffage, le dispositif de coiffage peut avoir une forme globalement plate. Par exemple la hauteur du dispositif de coiffage lorsque les branches sont en position de pré-coiffage peut être égale ou inférieure à la moitié, avantageusement au tiers, avantageusement au quart de la longueur d'une branche.For example, in pre-styling position, each branch can form with the longitudinal direction an angle of between 80 and 100 degrees, for example close to 90 degrees. In other words, when all the branches are in pre-styling position, the styling device can have a generally flat shape. For example, the height of the styling device when the branches are in the pre-styling position may be equal to or less than half, advantageously to one third, advantageously to a quarter of the length of a branch.

Une telle configuration plate peut permettre de faciliter la fabrication en ce sens que la conception d'un moule est relativement simple, que le démoulage peut être relativement aisé à effectuer.Such a flat configuration can facilitate manufacturing in the sense that the design of a mold is relatively simple, demolding can be relatively easy to perform.

On pourra par exemple prévoir un moulage à plat.For example, a flat molding may be provided.

Un moulage à plat peut permettre en outre de faciliter l'injection. Aussi, pour une même nature de fluide injecté, on pourra réaliser des branches éventuellement plus longues que dans l'art antérieur.A flat molding can also facilitate the injection. Also, for the same nature of injected fluid, may be made branches possibly longer than in the prior art.

Du fait de cette forme relativement plate, le stockage peut éventuellement être plus compact que dans l'art antérieur.Due to this relatively flat shape, the storage may be more compact than in the prior art.

Avantageusement et de façon non limitative, le dispositif de coiffage peut être réalisé d'une seule pièce. Le dispositif de coiffage peut ainsi être obtenu par moulage. Du fait de cette articulation entre les branches et le reste du dispositif de coiffage, la fabrication peut être facilitée.Advantageously and without limitation, the styling device can be made in one piece. The styling device can thus be obtained by molding. Because of this articulation between the branches and the rest of the styling device, the manufacture can be facilitated.

L'invention n'est cependant en rien limitée à un dispositif de coiffage réalisé d'une seule pièce On pourra par exemple prévoir une fixation des branches à l'élément support, puis un mouvement de rotation pour passer d'une position de pré-coiffage à une position de coiffage et/ou inversement.The invention is however in no way limited to a styling device made in one piece. For example, it is possible to provide a fixation of the branches to the support element and then a rotational movement to move from a pre-positioned position. styling at a styling position and / or vice versa.

Les branches peuvent être rectilignes, sur au moins une partie de leur longueur, ou non.The branches may be rectilinear, over at least part of their length, or not.

Les branches peuvent avoir une forme arrondie et/ou définir des angles abrupts.The branches may have a rounded shape and / or define steep angles.

Avantageusement et de façon non limitative, pour au moins une branche de la pluralité de branches, au moins une portion de cette au moins une branche a une forme convexe. L'enveloppe de coiffage peut avoir une forme convexe. Ceci peut permettre de définir un plus grand volume pour la lampe pour un diamètre d'orifice de couche basse de plafond donnée. Le moulage étant réalisé à plat, une telle forme convexe est relativement facile à obtenir.Advantageously and non-limitatively, for at least one branch of the plurality of branches, at least a portion of this at least one branch has a convex shape. The styling envelope may have a convex shape. This can make it possible to define a larger volume for the lamp for a given ceiling low layer orifice diameter. Since the molding is made flat, such a convex shape is relatively easy to obtain.

L'invention n'est en rien limitée par une forme convexe de l'enveloppe de coiffage.The invention is in no way limited by a convex shape of the styling envelope.

On pourra par exemple concevoir des branches concaves, permettant d'obtenir une enveloppe de coiffage de forme concave. Les dimensions de l'orifice de plafond peuvent ainsi être relativement élevées, ce qui peut être avantageux pour certaines lampes, du type extraplates par exemple.We can for example design concave branches, to obtain a styling envelope of concave shape. The dimensions of the ceiling hole can thus be relatively high, which may be advantageous for some lamps, of the extra flat type for example.

De manière générale, l'invention n'est en rien limitée par la forme des branches. On pourra prévoir des branches ayant chacune une forme de S, définissant des zigzag, des marches, et/ou autre.In general, the invention is in no way limited by the shape of the branches. One can provide branches each having a shape of S, defining zigzag, steps, and / or other.

Avantageusement et de façon non limitative, le dispositif de coiffage est agencé de façon à autoriser le mouvement de rotation entre la position de pré-coiffage jusqu'à la position de coiffage, et à empêcher un retour arrière une fois la position de coiffage atteinte.Advantageously and without limitation, the styling device is arranged to allow the rotational movement between the pre-styling position to the styling position, and to prevent a backward movement once the styling position is reached.

On pourra par exemple prévoir des moyens de clipsage pour empêcher ce retour arrière.For example, clipping means may be provided to prevent this backtracking.

Avantageusement et de façon non limitative, la branche articulée est reliée au reste du dispositif de coiffage, par exemple à l'élément support ou à au moins une autre branche, par un élément de charnière d'épaisseur suffisamment faible pour pouvoir être replié. Ainsi, le dispositif de coiffage peut-il être réalisé en une seule pièce, tout en autorisant des mouvements relatifs entre les branches et l'élément support.Advantageously and in a nonlimiting manner, the articulated branch is connected to the rest of the styling device, for example to the support element or to at least one other branch, by a hinge element of sufficiently small thickness to be folded. Thus, the styling device can be made in one piece, while allowing relative movements between the branches and the support member.

Avantageusement et de façon non limitative, le dispositif de coiffage est agencé de façon à, une fois la position de coiffage atteinte, autoriser un mouvement de rotation vers une deuxième position de pré-coiffage correspondant à une configuration compacte du dispositif de coiffage. Ainsi, en appuyant sur la branche articulée au-delà de la position de coiffage, on peut contraindre cette branche à se replier davantage, ce qui peut permettre par exemple d'introduire le dispositif de coiffage dans un orifice lors de l'installation dans le plafond.Advantageously and in a nonlimiting manner, the styling device is arranged so that, once the styling position has been reached, allow a rotational movement towards a second pre-styling position corresponding to a compact configuration of the styling device. Thus, by pressing on the articulated branch beyond the styling position, this branch can be forced to fold further, which may allow for example to introduce the styling device into an orifice during installation in the ceiling.

Avantageusement et de façon non limitative, l'élément de charnière est agencé de façon à appliquer de forces de rappel vers la position de coiffage lorsque la branche articulée est positionnée au-delà de la position de coiffage. Ainsi, si les branches articulées peuvent être précontraintes de sorte que le dispositif ait une conformation compacte, de tels moyens ressort tendent à écarter à nouveau les branches du dispositif de coiffage lorsque la contrainte a disparu.Advantageously and without limitation, the hinge element is arranged to apply restoring forces to the styling position when the articulated arm is positioned beyond the styling position. Thus, if the articulated branches can be prestressed so that the device has a compact conformation, such spring means tend to move the branches of the styling device again when the stress has disappeared.

Il est en outre proposé un procédé de montage d'un dispositif de coiffage de lampe de plafond, comportant une étape consistant à faire passer par un mouvement de rotation au moins une branche du dispositif de coiffage, articulée par rapport à au moins une autre branche du dispositif de coiffage, d'une position de pré-coiffage à une position de coiffage.There is further provided a method of mounting a ceiling lamp capping device, comprising a step of rotating at least one branch of the capping device, articulated with respect to at least one other branch. of the styling device, from a pre-styling position to a styling position.

Les branches du dispositif de coiffage peuvent former un ensemble formant une structure de coiffage et/ou définissant une enveloppe de coiffage permettant de protéger la lampe d'une nappe de matière isolante.The branches of the styling device can form an assembly forming a styling structure and / or defining a styling envelope for protecting the lamp with a sheet of insulating material.

L'invention peut trouver une application dans le coiffage de lampes de petites dimensions (le dispositif de coiffage a par exemple une section à sa base de 3 à 5 cm de diamètre lorsque les branches sont en position de coiffage), moyennes dimensions (le dispositif de coiffage a par exemple une section à sa base de 5 à 10 cm de diamètre lorsque les branches sont en position de coiffage) ou grandes dimensions (le dispositif de coiffage a par exemple une section à sa base de 10 à 40 cm de diamètre lorsque les branches sont en position de coiffage).The invention can find an application in the capping of lamps of small dimensions (the styling device has for example a section at its base of 3 to 5 cm in diameter when the branches are in the styling position), medium dimensions (the device for example a section at its base of 5 to 10 cm in diameter when the branches are in the styling position) or large dimensions (the styling device has for example a section at its base of 10 to 40 cm in diameter when the branches are in styling position).

Dans la présente demande, les termes « haut », « bas », « dessus », « dessous », « vertical », « horizontal », « latéral », etc. sont à prendre lorsque le dispositif de coiffage a une orientation correspondant à une utilisation classique, c'est-à-dire que le vecteur gravité est suivant la direction verticale, orienté depuis le haut vers le bas, et parallèle à la direction longitudinale de symétrie du dispositif de coiffage. Bien entendu, le dispositif de coiffage est susceptible d'adopter d'autres orientations, notamment lors de sa fabrication, transport, stockage, etc.In the present application, the terms "up", "down", "above", "below", "vertical", "horizontal", "lateral", etc. are to be taken when the styling device has an orientation corresponding to a conventional use, that is to say that the gravity vector is in the vertical direction, oriented from the top down, and parallel to the longitudinal direction of symmetry of the styling device. Of course, the styling device is likely to adopt other orientations, especially during its manufacture, transport, storage, etc.

En référence à la figure 1A, le dispositif de coiffage 1 comporte trois branches 2 et un élément support 3.With reference to the Figure 1A , the styling device 1 comprises three branches 2 and a support element 3.

L'invention n'est en rien limitée par le nombre de branches du dispositif de coiffage : on pourra par exemple prévoir, quatre branches, cinq branches, ou davantage. L'invention n'est pas non plus limitée par le nombre de branches articulées parmi l'ensemble des branches du dispositif de coiffage : on pourra prévoir, seulement une branche articulée, deux branches articulées, ou bien encore que la totalité des branches de l'ensemble de branches soient articulées, etc.The invention is in no way limited by the number of branches of the styling device: it will be possible for example to provide, four branches, five branches, or more. The invention is also not limited by the number of articulated branches among all the branches of the styling device: it will be possible to provide, only an articulated branch, two articulated branches, or even that all the branches of the set of branches are articulated, etc.

Les branches 2 sont reliées à l'élément support 3 par des éléments charnières 10 de relativement faible épaisseur.The branches 2 are connected to the support member 3 by hinge elements 10 of relatively small thickness.

Les branches 2, les éléments charnières 10, et l'élément support 3 sont moulés d'une seule pièce. Du fait de la forme relativement plane du dispositif 1, dans la configuration de la figure 1a, le moulage est relativement aisé à effectuer.The branches 2, the hinge elements 10, and the support element 3 are molded in one piece. Due to the relatively flat shape of the device 1, in the configuration of the figure 1a the molding is relatively easy to perform.

En référence à la figure 1B, la branche articulée 2 s'étend en un élément de clipsage 12. L'élément support 3 définit également une saillie de clipsage 13 destinée à coopérer avec l'élément de clipsage 12 lorsque la branche 2 est repliée.With reference to the Figure 1B the articulated branch 2 extends into a clipping member 12. The support member 3 also defines a clipping projection 13 intended to cooperate with the clipping element 12 when the branch 2 is folded.

Une fois le dispositif 1 moulé, et éventuellement transporté, on replie une à une chacune des branches 2 de façon à les rapprocher les unes des autres. Pour chaque branche 2, un angle entre une direction longitudinale suivant un axe (D) et une direction selon un axe (D2)suivant laquelle s'étend au moins partiellement la branche 2, diminue au cours de ce mouvement.Once the device 1 molded, and possibly transported, is folded one to one each of the branches 2 so as to bring them closer to each other. For each branch 2, an angle between a longitudinal direction along an axis (D) and a direction along an axis (D 2 ) along which at least partially extends the branch 2, decreases during this movement.

Cette direction longitudinale, selon l'axe (D) est confondue avec un axe de symétrie de l'enveloppe de coiffage lorsque toutes les branches sont dans la position de coiffage, comme représenté sur la figure 2A. Cette direction (D) est sensiblement perpendiculaire à une surface tangente au centre de la surface supérieure de l'élément 3.This longitudinal direction, along the axis (D) coincides with an axis of symmetry of the styling envelope when all the branches are in the styling position, as shown in FIG. Figure 2A . This direction (D) is substantially perpendicular to a surface tangent to the center of the upper surface of the element 3.

Du fait de ce repliement de la branche 2, une surface de coulissement 121 de l'élément de clipsage 12 est déplacée le long d'une surface de coulissement 131 de la saillie de clipsage 13, puis une surface de clipsage 122 vient en butée contre une surface de clipsage 132 de cette saillie 13.Due to this folding of the branch 2, a sliding surface 121 of the clipping element 12 is moved along a sliding surface 131 of the clipping projection 13, then a clipping surface 122 abuts against a clipping surface 132 of this projection 13.

La branche 2 a alors atteint la position de coiffage, et ce clipsage interdit de revenir facilement à la conformation plate de la figure 1A. Les surfaces 122, 132 étant en butée l'une contre l'autre, il n'est plus possible de ré-écarter les branches les unes des autres, à moins d'exercer une pression sur une surface de déblocage 133, appartenant à la saillie 13, ce qui permettrait d'incliner vers l'intérieur du dispositif de coiffage cette saillie 13, et de libérer la branche 2.Branch 2 then reached the styling position, and this clipping prohibits easy return to the flat conformation of the Figure 1A . The surfaces 122, 132 being in abutment against each other, it is no longer possible to re-separate the branches from each other, unless exerting pressure on a release surface 133, belonging to the projection 13, which would tilt inward of the styling device this projection 13, and release the branch 2.

La figure 2B montre un détail de l'articulation entre une branche articulée 2 et l'élément support 3, dans lequel on voit les surfaces de clipsage 122, 132 l'une contre l'autre.The Figure 2B shows a detail of the articulation between an articulated branch 2 and the support element 3, in which we see the clipping surfaces 122, 132 against each other.

On notera toutefois qu'une surface d'extrémité 124 solidaire de la branche 2 n'a pas encore atteint une surface de butée 135 de l'élément support 3.Note however that an end surface 124 secured to the branch 2 has not yet reached an abutment surface 135 of the support member 3.

Si l'on continue d'appliquer une pression sur les branches 2, les branches 2 peuvent donc encore être repliées, de sorte que le dispositif de coiffage adopte une conformation compacte, comme représenté sur la figure 3A.If we continue to apply pressure on the branches 2, the branches 2 can therefore still be folded, so that the styling device adopts a compact conformation, as shown in FIG. figure 3A .

Les surfaces de clipsage 122, 132 sont alors éloignées l'une de l'autre, et la course de la branche 2 n'est limitée que lorsque la surface d'extrémité 124 atteint la surface de butée 135 de l'élément support 3.The clipping surfaces 122, 132 are then moved away from each other, and the stroke of the limb 2 is limited only when the end surface 124 reaches the abutment surface 135 of the support member 3.

Lorsque les branches sont dans cette position contrainte, l'élément charnière 10 se trouve alors étiré et exerce un effort tendant à écarter à nouveau les branches de la direction longitudinale. Un tel effet ressort permet au dispositif de coiffage de retrouver une position relativement écartée lorsque la contrainte a disparu.When the branches are in this constrained position, the hinge element 10 is then stretched and exerts a force tending to move the branches away from the longitudinal direction. Such a spring effect allows the styling device to find a relatively remote position when the stress has disappeared.

Ainsi, il est possible de resserrer les branches les unes contre les autres de façon à pouvoir introduire le dispositif de coiffage 1 dans un orifice de plafond, par exemple manuellement. Une fois le dispositif 1 introduit dans le plafond, la contrainte a disparue et les branches tendent à s'écarter l'une de l'autre. Les branches sont limitées dans cette course par les bords de l'orifice contre lesquels viennent les parties 30 des branches 2.Thus, it is possible to tighten the branches against each other so as to introduce the styling device 1 in a ceiling hole, for example manually. Once the device 1 introduced into the ceiling, the stress has disappeared and the branches tend to deviate from one another. The branches are limited in this race by the edges of the orifice against which the parts 30 of the branches 2 come.

On relèvera que les branches 2 ont une forme relativement convexe entre l'articulation à l'élément support 3 et cette partie 30. Ceci peut permettre d'obtenir un volume de coiffage relativement élevé pour un diamètre d'orifice de plafond donné.It will be noted that the branches 2 have a relatively convex shape between the articulation with the support element 3 and this part 30. This can make it possible to obtain a relatively high styling volume for a given ceiling orifice diameter.

Dans le mode de réalisation représenté, des doigts 230 solidaires de l'élément support 3, permettent, en cas de rupture de l'élément charnière 10, un certain maintien de la branche correspondante 2 en empêchant tout déplacement latéral de cette branche. Des doigts 230 peuvent en outre permettre de venir limiter la course de la branche 2 en venant en contact avec des surfaces latérales 220 de ces branches 2.In the embodiment shown, fingers 230 secured to the support member 3, in case of rupture of the hinge element 10, allow some maintenance of the corresponding branch 2 by preventing any lateral movement of this branch. Fingers 230 can also be used to limit the stroke of the limb 2 by coming into contact with lateral surfaces 220 of these limbs 2.
