Abstract
Description
La présente invention concerne le domaine de l'éclairage zénithal en relation avec les couvertures de toits et a pour objet un lanterneau d'éclairage zénithal avec protection solaire.The present invention relates to the field of zenith lighting in connection with roof covers and is for a skylight skylight with solar protection.
On sait qu'un lanterneau d'éclairage zénithal est généralement constitué par une costière destinée à être fixée dans une ouverture pratiquée dans une couverture de toit et par une couverture de remplissage et de fermeture translucide ou transparente, réalisée généralement à partir d'un matériau de remplissage en polycarbonate, fixée sur la costière par l'intermédiaire d'un cadre support fixe ou, dans le cas d'un lanterneau susceptible d'être ouvert pour assurer également des fonctions de ventilation, de désenfumage ou d'accès à la toiture, d'un cadre support ouvrant.It is known that a zenith lighting skylight is generally constituted by a curb intended to be fixed in an opening made in a roof covering and by a translucent or transparent filling and closing cover, generally made from a material polycarbonate filler, fixed on the curb by means of a fixed support frame or, in the case of a skylight that can be opened to also perform functions of ventilation, smoke extraction or access to the roof , an opening support frame.
La couverture de remplissage et de fermeture est maintenue généralement dans une feuillure du cadre support fixe ou ouvrant au moyen d'une parclose ou similaire et joue donc le rôle d'un vitrage en participant à la fermeture totale de l'ouverture d'éclairage zénithal pratiquée dans la toiture, tout en laissant passer la lumière du soleil pour permettre l'éclairage zénithal de l'espace intérieur situé sous ladite toiture.The filling and closure cover is generally held in a rabbet of the fixed or opening support frame by means of a bead or the like and therefore plays the role of a glazing by participating in the total closure of the zenith lighting opening practiced in the roof, while allowing the light of the sun to pass to allow the zénithal lighting of the interior space located under said roof.
Par ailleurs, pour répondre aux problèmes de protection solaire et éviter des élévations de température trop importantes, on a proposé de disposer des stores dans l'espace intérieur, sous la couverture de remplissage. Toutefois, ces stores arrêtent les rayonnements solaires uniquement dans l'espace intérieur, ce qui a pour résultat de créer un effet de serre et donc un réchauffement de l'espace intérieur, principalement durant les périodes les plus chaudes de l'année. En outre les lames de ces stores sont souvent orientables et nécessitent généralement, à cet effet, des dispositifs spécifiques pour piloter l'orientation des lames et donc des besoins de raccordement à des sources d'énergie pour leur actionnement.In addition, to meet the problems of sun protection and to avoid excessive temperature rises, it has been proposed to have blinds in the interior space, under the filling cover. However, these blinds stop solar radiation only in the interior space, which results in a greenhouse effect and thus a warming of the interior space, mainly during the hottest periods of the year. In addition, the blades of these blinds are often orientable and generally require, for this purpose, specific devices for controlling the orientation of the blades and therefore the connection requirements to energy sources for their actuation.
Pour remédier à ces inconvénients, plusieurs solutions, consistant à rajouter une protection solaire au-dessus de la couverture de remplissage et de fermeture et à l'extérieur du lanterneau, ont été proposées.To overcome these disadvantages, several solutions, consisting of adding a sunscreen over the filling and closing cover and outside the skylight, have been proposed.
C'est ainsi que le document
Toutefois, ce type de protection solaire occulte une grande partie de l'ouverture d'éclairage zénithal du lanterneau, ce qui a pour effet une perte importante de l'éclairement dans l'espace intérieur bénéficiant de l'éclairage zénithal. En outre, l'écran forme une surface qui s'étend au-delà de la couverture du toit en générant une forte prise au vent, à l'instar d'une voile, ce qui entraîne des risques d'arrachement de l'écran et des bruits de sifflement du vent au contact de l'écran. Enfin, ce type de protection solaire génère des problèmes d'encrassement de l'écran et des dépôts de saletés entre ce dernier et l'élément translucide du lanterneau.However, this type of sun protection obscures much of the zenith lighting opening of the skylight, which has the effect of a significant loss of illumination in the interior space benefiting from the zenith lighting. In addition, the screen forms a surface that extends beyond the roof cover generating a strong windward grip, like a sail, which leads to the risk of tearing off the screen and wind whistling noises on the screen. Finally, this type of sunscreen generates problems of clogging of the screen and dirt deposits between the latter and the translucent element of the skylight.
Il a également été proposé de positionner une grille en aluminium ajourée au-dessus de la couverture de remplissage et de fermeture pour occulter la moitié de la surface de cette dernière afin de réduire les apports en chaleur dans le local concerné. Toutefois, la surface occultée a pour conséquence de diminuer fortement l'éclairement dans ledit local qui reste sombre, notamment, dans des conditions de ciel couvert. D'autre part, en cas de rayonnement solaire direct, il apparaît un contraste important entre la partie éclairée et la partie occultée par la grille. En outre, la dilatation différentielle entre la grille aluminium et le matériau en polycarbonate de la couverture de remplissage et de fermeture génère des rayures sur ledit matériau. Enfin, ce type de brise soleil produit un encrassement inévitable de la couverture de remplissage et de fermeture et de la grille aluminium qui a pour effet d'accélérer le vieillissement du lanterneau.It has also been proposed to position a perforated aluminum grid over the filling and closure cover to conceal half of the surface of the latter to reduce the heat input into the room concerned. However, the obscured surface has the effect of greatly reducing the illumination in said room which remains dark, especially under cloudy conditions. On the other hand, in case of direct solar radiation, there is a significant contrast between the illuminated portion and the portion obscured by the grid. In addition, the differential expansion between the aluminum grid and the polycarbonate material of the filling and closure cover generates scratches on said material. Finally, this type of sunscreen produces an inevitable fouling of the filling and closing cover and the aluminum grid which has the effect of accelerating the aging of the skylight.
En outre, de manière à réduire la pénétration des rayonnements solaires directs, il a également été proposé de tendre une toile en matière plastique ou en textile, perforée ou non, au-dessus du remplissage du lanterneau. Cependant, une telle solution entraîne une perte de lumière dans le local concerné, notamment en cas de ciel couvert. D'autre part, la toile est fréquemment encrassée par son exposition permanente aux conditions extérieures et présente des risques d'arrachement par sa forte prise au vent. Par ailleurs, la toile doit être transportée séparément du lanterneau et montée sur site.In addition, so as to reduce the penetration of direct solar radiation, it has also been proposed to stretch a plastic cloth or fabric, perforated or not, above the filling of the skylight. However, such a solution causes a loss of light in the local concerned, especially in case of overcast. On the other hand, the canvas is frequently fouled by its permanent exposure to external conditions and presents risks of tearing by its strong hold in the wind. In addition, the canvas must be transported separately from the skylight and mounted on site.
Une autre solution proposée consiste à réaliser une surélévation du lanterneau constituée de deux faces en pente orientées différemment, une face opaque orientée côté Sud et une face en pente translucide orientée côté Nord. Toutefois, cette solution exige une orientation spécifique de la face opaque côté Sud et génère une réduction notable de la surface laissant passer la lumière à travers le lanterneau.Another proposed solution consists of raising the skylight consisting of two differently oriented sloping faces, an opaque face oriented on the south side and a translucent sloping face oriented on the north side. However, this solution requires a specific orientation of the opaque side South side and generates a significant reduction in the area allowing light to pass through the skylight.
Il a également été proposé comme protection solaire dissociée du vitrage une structure de lames inclinées ou verticales montée au-dessus du vitrage. Une telle structure offre une protection solaire efficace mais avec une perte importante en lumière, notamment dans le cas de lames inclinées. En outre ce type de structure présente des risques d'arrachement dus à sa forte prise au vent et une conception complexe, notamment dans le cas de lames verticales par le calcul de la hauteur et de l'espacement entre les lames qu'il convient d'effectuer.It has also been proposed as solar protection dissociated glazing a structure of inclined or vertical blades mounted above the glazing. Such a structure provides effective sun protection but with a significant loss of light, especially in the case of inclined blades. In addition, this type of structure has the risk of tearing due to its high wind resistance and a complex design, especially in the case of vertical blades by the calculation of the height and the spacing between the blades that should be used. 'carry out.
D'autres solutions qui ont été proposées concernent les caractéristiques du remplissage et tentent de réduire la transmission énergétique des matériaux de remplissage, en intégrant, par exemple, dans ce dernier un filtre anti-infrarouges ou un filtre de pigments métalliques. Cependant, la transmission lumineuse obtenue avec ces filtres ou pigments baisse, ce qui entraîne une perte importante de lumière dans le local concerné.Other solutions that have been proposed relate to the characteristics of the filling and try to reduce the energy transmission of the filling materials, for example by incorporating in the latter an anti-infrared filter or a metal pigment filter. However, the light transmission obtained with these filters or pigments decreases, resulting in a significant loss of light in the room concerned.
Il a encore été proposé d'appliquer des films de protection solaire sur la face interne ou externe du remplissage. Toutefois, si ces films permettent d'obtenir une baisse de la transmission lumineuse et de la transmission énergétique, leur tenue dans le temps n'est pas de bonne qualité et génère à la longue des craquelures sur le film, dus à la dilatation différentielle entre le matériau de remplissage et le film. En outre ces films offrent une faible résistance aux rayures.It has also been proposed to apply sun protection films on the inner or outer face of the filling. However, if these films make it possible to obtain a reduction in the light transmission and the energy transmission, their behavior over time is not of good quality and in the long run generates cracks on the film, due to the differential expansion between the filling material and the film. In addition, these films offer low scratch resistance.

Toutefois, la lanterneau décrit dans ce dernier document, ainsi que les autres protections solaires connues, ne permettent pas d'obtenir une structure de protection solaire coupant ou brisant les rayonnements solaires directs et préservant le niveau de lumière transmis à travers l'ouverture d'éclairage zénithal tout en procurant une isolation thermique et/ou phonique efficace et élevée.However, the skylight described in this last document, as well as the other known solar protections, do not make it possible to obtain a solar protection structure cutting or breaking the direct solar radiation and preserving the level of light transmitted through the opening of zenith lighting while providing effective and high thermal and / or sound insulation.
La présente invention a pour but de pallier ces inconvénients en proposant un dispositif de protection solaire ne nécessitant pas d'orientation particulière par rapport aux points cardinaux et permettant notamment de couper les rayonnements directs du soleil, tout en conservant un niveau de lumière diffuse important dans le local concerné, notamment en conditions de ciel couvert, et en améliorant notablement l'isolation phonique e thermique procurés par les systèmes existants et décrits dans les documents précités.The aim of the present invention is to overcome these drawbacks by proposing a sun protection device that does not require any particular orientation with respect to the cardinal points and that makes it possible, in particular, to cut off the direct radiation of the sun, while maintaining a level of significant diffuse light in the room concerned, especially in overcast conditions, and significantly improving the sound and heat insulation provided by the existing systems and described in the aforementioned documents.
A cet effet, le lanterneau d'éclairage zénithal, avec protection solaire, selon la présente invention, comprend d'une part, une costière apte à être fixée, de façon étanche, dans une ouverture d'éclairage zénithal pratiquée dans une couverture de toit et une couverture de remplissage et de fermeture, en matériau étanche translucide ou transparent, permettant l'éclairage zénithal et la fermeture totale de l'ouverture d'éclairage zénithal, ladite couverture de remplissage et de fermeture étant fixée sur la costière par l'intermédiaire d'un cadre support fixe ou ouvrant et, d'autre part, des moyens de protection solaire.For this purpose, the skylight skylight, with sun protection, according to the present invention, comprises firstly, a curb adapted to be fixed, in a sealed manner, in a zenith lighting opening made in a roof covering and a filling and closure cover, in translucent or transparent waterproof material, for zenith lighting and total closure of the zenith lighting aperture, said filling and closure cover being attached to the curb via a fixed or opening support frame and, on the other hand, sun protection means.
Un tel lanterneau selon la présente invention se caractérise essentiellement en ce que :
- lesdits moyens de protection solaire consistent en un écran rigide, à extension surfacique, s'étendant au-dessus ou au-dessous de ladite couverture de remplissage et de fermeture, ledit écran présentant la forme d'une plaque sensiblement plane ou légèrement bombée, dont l'âme est constituée par une structure en nid d'abeille comprenant une juxtaposition de passages prismatiques, dont les axes sont orientés, d'une part, sensiblement perpendiculairement aux plans contenant les grandes faces de ladite plaque ou obliquement par rapport aux normales desdits plans et, d'autre part, parallèlement ou obliquement par rapport à l'axe de l'ouverture d'éclairage zénithal, ladite structure en nid d'abeille étant apte, notamment, à couper ou à briser les rayonnements directs du soleil, en amont de ladite ouverture d'éclairage zénithal et à réguler de manière passive le niveau de lumière ainsi transmis,
- l'écran et la couverture de remplissage et de fermeture, présentant également une forme de plaque, s'étendent sensiblement parallèlement l'un par rapport à l'autre en étant séparés l'un de l'autre, avec une lame d'air intercalaire, immobile ou ventilée, avec une entretoise périphérique, continue ou discontinue, à rupture de pont thermique ou sans rupture de pont thermique, ledit écran et ladite couverture de remplissage et de fermeture formant un ensemble, du type double vitrage, fixé sur la costière par l'intermédiaire du cadre support fixe ou ouvrant.
- said sun protection means consist of a rigid, surface-extending screen extending above or below said filling and closure cover, said screen having the shape of a substantially flat or slightly curved plate, of which the core consists of a honeycomb structure comprising a juxtaposition of prismatic passages, whose axes are oriented, on the one hand, substantially perpendicular to the planes containing the large faces of said plate or obliquely to the normal of said planes and, secondly, parallel or obliquely to the axis of the zenith lighting aperture, said honeycomb structure being able, in particular, to cut or break the direct radiation of the sun, upstream of said zenith lighting aperture and to passively regulate the level of light thus transmitted,
- the screen and the filling and closure cover, also having a plate-like shape, extend substantially parallel to each other while being separated from one another, with an air gap interlayer, immobile or ventilated, with a peripheral spacer, continuous or discontinuous, thermal break or without thermal break, said screen and said filling and closure cover forming a set, of the double glazing type, fixed on the curb through the fixed or opening support frame.

Les figures montrent un lanterneau d'éclairage zénithal, avec protection solaire, selon la présente invention, ledit lanterneau comprenant, d'une part, une costière 1 apte à être fixée, de façon étanche, dans une ouverture d'éclairage zénithal 2 pratiquée dans une couverture de toit 3 et une couverture de remplissage et de fermeture 4, en matériau étanche translucide ou transparent, permettant l'éclairage zénithal et la fermeture totale de l'ouverture d'éclairage zénithal 2, ladite couverture de remplissage et de fermeture 4 étant fixée sur la costière 1 par l'intermédiaire d'un cadre support 5 fixe ou ouvrant et, d'autre part, des moyens de protection solaire 7.The figures show a zenith lighting skylight, with solar protection, according to the present invention, said skylight comprising, on the one hand, a
Conformément à la présente invention, lesdits moyens de protection solaire consistent en un écran 7 rigide, à extension surfacique, s'étendant au-dessus ou au-dessous de ladite couverture de remplissage et de fermeture 4. En outre, l'écran 7 présente la forme d'une plaque sensiblement plane ou légèrement bombée, dont l'âme est constituée par une structure en nid d'abeille 9 comprenant une juxtaposition de passages prismatiques 10, dont les axes 10' sont orientés, d'une part, sensiblement perpendiculairement aux plans contenant les grandes faces de ladite plaque ou obliquement par rapport aux normales desdits plans et, d'autre part, parallèlement ou obliquement par rapport à l'axe de l'ouverture d'éclairage zénithal 2. D'autre part, la structure en nid d'abeille est apte, notamment, à couper ou à briser les rayonnements directs du soleil, en amont de ladite ouverture d'éclairage zénithal 2 et à réguler de manière passive le niveau de lumière ainsi transmis.According to the present invention, said sun protection means consist of a
Toujours conformément à la présente invention la couverture de remplissage et de fermeture 4 présente également une forme de plaque et cette dernière et l'écran 7 s'étendent sensiblement parallèlement l'un par rapport à l'autre en étant séparés l'un de l'autre, avec une lame d'air intercalaire, immobile ou ventilée, avec une entretoise 12 périphérique, continue ou discontinue, à rupture de pont thermique ou sans rupture de pont thermique. L'écran 7 et la couverture de remplissage et de fermeture 4 forment alors un ensemble du type double vitrage, fixé sur la costière 1 par l'intermédiaire du cadre support 5 fixe ou ouvrant.Still in accordance with the present invention the filling and
Dans un mode de réalisation préférentiel, l'âme de la plaque formant la couverture de remplissage et de fermeture 4 peut être constituée par une structure en nid d'abeille 9 comprenant une juxtaposition de passages prismatiques 10, d'axes 10' orientés sensiblement parallèlement ou obliquement par rapport à l'axe de l'ouverture d'éclairage zénithal 2, apte, notamment, à couper ou à briser les rayonnements directs du soleil, en amont de l'ouverture d'éclairage zénithal 2 et à réguler de manière passive le niveau de lumière ainsi transmis, les axes 10' des passages prismatiques 10 de ladite structure en nid d'abeille 9 étant orientés sensiblement perpendiculairement aux plans contenant les grandes faces de ladite plaque ou obliquement par rapport aux normales desdits plans.In a preferred embodiment, the core of the plate forming the filling and
La présente invention peut prévoir que l'une et/ou l'autre des grandes faces de la plaque de l'écran 7 et/ou de la plaque de la couverture de remplissage et de fermeture 4 (
Le matériau de remplissage de la couverture de remplissage et de fermeture 4 peut être un matériau massif ou alvéolaire, plastique ou verrier, transparent, translucide ou coloré et peut se présenter sous une forme sensiblement plane ou bombée.The filling material of the filling and
On comprendra alors qu'une plaque en nid d'abeille, selon la présente invention, peut comporter soit un noyau en nid d'abeille cloisonné entre une ou deux peaux 11, soit uniquement un noyau en nid d'abeille sans peau(x).It will be understood that a honeycomb plate, according to the present invention, may comprise either a honeycomb core partitioned between one or two
En outre, si on se réfère à la
Les passages prismatiques 10 peuvent être pleins ou, préférentiellement, creux (
Par ailleurs, les passages prismatiques 10 d'une structure en nid d'abeille 9 de l'écran 7 et, éventuellement, de la couverture de remplissage et de fermeture 4 peuvent avantageusement être arrangés en quinconce, ce de manière à pouvoir réduire les dimensions desdits passages prismatiques 10.Furthermore, the
La rupture thermique peut être obtenue, comme on peut le voir sur la
D'autre part, comme on peut le voir sur la
On comprendra que, dans le cas d'un lanterneau comportant un cadre support 5 ouvrant, la couverture de remplissage et de fermeture 4 et l'écran 7 sont rendus mobiles ensemble avec ledit cadre support 5.It will be understood that, in the case of a skylight comprising an
Par ailleurs, on notera qu'un cadre support 5 fixe ou ouvrant, selon la présente invention, peut être un cadre classique ou d'adaptation avec parclose ou similaire, ou être uniquement une parclose ou cadre parclose. Plus particulièrement, dans le cas d'un lanterneau comportant un cadre support ouvrant, une parclose peut venir en périphérie de la couverture de remplissage et de fermeture et peut être fixée sur ledit cadre support ouvrant, lui-même fixé sur la costière.Furthermore, it will be noted that a
Ainsi une structure de protection solaire en nid d'abeille intégrée dans un écran 7 et/ou dans la couverture de remplissage et de fermeture 4, l'un placé au-dessus de l'autre ou réciproquement, selon la présente invention, permet de couper les rayonnements solaires directs par un effet de diffraction et/ou de réflexion sur les parois des passages prismatiques 10 et de préserver le niveau de lumière diffuse transmis à travers lesdits passages prismatiques 10. Elle permet également de réduire la transmission énergétique par diffraction, réflexion et coupure et de baisser simultanément le facteur solaire du flux lumineux. Elle permet, d'autre part de réguler le sens du flux lumineux. Ceci permet de prévenir toutes les sources d'inconfort, telles que l'échauffement, l'éblouissement ou encore les taches solaires, à l'intérieur du local bénéficiant de l'éclairage zénithal.Thus a honeycomb solar protection structure integrated in a
Enfin, la superposition des deux éléments en forme de plaque écran 7 et couverture de remplissage et de fermeture 4, qui forment avec la lame d'air un complexe similaire à un double vitrage, permet d'améliorer notablement la performance acoustique et thermique du lanterneau, en diminuant, par exemple, le bruit de chute de pluie sur la face externe du lanterneau.Finally, the superposition of the two elements in the form of a
Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications are possible, particularly from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
