Description

La présente invention concerne un dispositif de protection contre les rayonnements solaires de constructions, en particulier de constructions vitrées, qui est escamotable et qui peut être monté sur des parois verticales, horizontales ou inclinées de constructions vitrées telles que des annexes à un bâtiment, des serres, des vérandas, des pergolas, des terrasses, des balcons couverts par exemple,... etc.The present invention relates to a device for protection against solar radiation from constructions, in particular from glazed constructions, which is retractable and which can be mounted on vertical, horizontal or inclined walls of glazed constructions such as annexes to a building, greenhouses , verandas, pergolas, terraces, covered balconies for example, ... etc.

Le but de la présente invention vise à fournir un dispositif du type susmentionné qui est escamotable et commandable à distance via un moyen d'entraînement intégré.The object of the present invention is to provide a device of the aforementioned type which is retractable and remotely controllable via an integrated drive means.

Un autre but de la présente invention vise à fournir un dispositif du type susmentionné qui peut être adapté à toute construction vitrée mentionnée ou analogue.Another object of the present invention is to provide a device of the aforementioned type which can be adapted to any glass construction mentioned or the like.

La présente invention porte sur un dispositif de protection contre les rayonnements solaires qui comporte au moins une toile, un moyen d'enroulement de celle-ci, fixé à une extrémité de celle-ci, associé à un mécanisme de tension de ladite toile, ledit mécanisme de tension consistant en au moins deux câbles qui s'étendent, respectivement, de poulies d'enroulement calées sur le moyen d'enroulement jusqu'aux roulettes de renvoi montées au niveau de déroulement maximum de la toile, sur lesquelles ils sont déviés d'environ 180° pour rejoindre, via des roulettes, un profilé de guidage fixé à l'autre extrémité de la toile dans lequel les deux câbles sont maintenus tendus par un ressort.The present invention relates to a device for protection against solar radiation which comprises at least one fabric, a winding means thereof, fixed to one end thereof, associated with a tensioning mechanism of said fabric, said tensioning mechanism consisting of at least two cables which extend, respectively, from winding pulleys wedged on the winding means up to the idler rollers mounted at the maximum unwinding level of the fabric, on which they are deflected d 'about 180 ° to join, via rollers, a guide profile fixed to the other end of the fabric in which the two cables are held tensioned by a spring.

L'enroulement de la toile sur son arbre et l'enroulement du câble sur sa poulie d'entraînement sont inverses de manière à éviter de devoir reprendre par le ressort des différences trop importantes. Des formes d'exécution de ce type de montage sont décrites et/ou représentées dans les documents FR-A-8 61 816 (Etablissements Ad. Mischler), FR-A-2 546 869 (José) et FR-A-2 559 527 (Aquitaine Fermetures).The winding of the fabric on its shaft and the winding of the cable on its drive pulley are reversed so as to avoid having to take up too large differences from the spring. Embodiments of this type of assembly are described and / or represented in documents FR-A-8 61 816 (Etablissements Ad. Mischler), FR-A-2 546 869 (José) and FR-A-2 559 527 (Aquitaine Fermetures).

Il faut observer que lors du déroulement de la toile, le diamètre extérieur-de la toile enroulée diminue tandis que l'enroulement en sens inverse du câble se fait sur un diamètre extérieur croissant. Il en résulte nécessairement des modifications de la longueur du ressort.It should be noted that during the unwinding of the fabric, the outside diameter of the wound fabric decreases while the winding in the opposite direction of the cable is done on an increasing outside diameter. This necessarily results in changes in the length of the spring.

Dans les formes d'exécution de l'état de la technique précité, les câbles sont toujours fixés par leurs extrémités respectives de part et d'autre d'un ressort de traction.In the embodiments of the aforementioned prior art, the cables are always fixed by their respective ends on either side of a tension spring.

Or, pour des portées relativement importantes de la toile, l'élongation du ressort entre la position enroulée de la toile et sa position déroulée peut être relativement importante et si la toile est relativement étroite, on peut ne pas disposer d'une longueur suffisante pour permettre une élongation suffisante du ressort.However, for relatively large spans of the fabric, the elongation of the spring between the wound position of the fabric and its unwound position may be relatively large and if the fabric is relatively narrow, it may not have a sufficient length to allow sufficient elongation of the spring.

Pour resoudre cette difficulté le ressort est selon la caractéristique de l'invention, solidaire des deux roulettes sur lesquelles sont déviés les câbles respectifs avant d'être fixés à l'intérieur du profilé de guidage sur deux points de fixationTo resolve this difficulty, the spring is, according to the characteristic of the invention, integral with the two rollers on which the respective cables are deflected before being fixed inside the guide profile on two fixing points.

Cette fixation peut être directe mais l'on peut également intercaler un second jeu de poulies pour encore multiplier la course du câble par deux si on le souhaite.This fixing can be direct but one can also insert a second set of pulleys to further multiply the cable travel by two if desired.

Il est évidemment important que le ressort soit dimensionné de manière à pouvoir reprendre, sous tension, la différence résultant des diamètres extérieurs variables d'enroulement de la toile et des câbles respectivement sur l'arbre et leurs poulies.It is obviously important that the spring is dimensioned so as to be able to take up, under tension, the difference resulting from the variable external diameters of winding of the fabric and of the cables respectively on the shaft and their pulleys.

Selon une forme d'exécution particulièrement avantageuse de l'invention on peut adjoindre au dispositif décrit au moins deux glissières dans lesquelles coulisse ledit profilé de guidageAccording to a particularly advantageous embodiment of the invention, it is possible to add to the device described at least two slides in which said guide profile slides.

Le dispositif de protection selon l'invention peut être monté à l'extérieur ou à l'intérieur de vérandas par exemple, tant sur une surface verticale que sur une surface horizontale ou inclinée.The protective device according to the invention can be mounted outside or inside verandas for example, both on a vertical surface and on a horizontal or inclined surface.

Avantageusement, le moyen d'enroulement consiste en un arbre d'enroulement entraîné en rotation par au moins un moteur qui est, de préférence, intégré dans ledit arbre. La toile est fixée de manière connue en soi à l'arbre d'enroulement, comme par exemple par serrage dans une rainure longitudinale de celui-ci, au moyen d'une barrette.Advantageously, the winding means consists of a winding shaft driven in rotation by at least one motor which is preferably integrated in said shaft. The fabric is fixed in a manner known per se to the winding shaft, for example by clamping in a longitudinal groove thereof, by means of a bar.

L'extrémité de la toile opposée à l'arbre d'enroulement est fixée de manière classique à un profilé de guidage, par exemple de manière analogue à la fixation à l'arbre d'enroulement. Ledit profilé de guidage permet de tendre la toile dans son sens longitudinal et permet également de couvrir au moins partiellement le mécanisme de tension de celle-ci.The end of the fabric opposite to the winding shaft is conventionally fixed to a guide profile, for example in a manner analogous to the fixing to the winding shaft. Said guide profile makes it possible to tension the fabric in its longitudinal direction and also makes it possible at least partially to cover the tensioning mechanism thereof.

Ledit profilé de guidage coulisse dans deux glissières latérales qui peuvent également comporter au moins une partie du mécanisme de tension de la toile. Selon les dimensions de la surface à couvrir, et en vue d'empêcher une flèche trop importante de la toile qui pourrait alors venir en contact avec la surface vitrée, il peut s'avérer nécessaire de couvrir la surface vitrée voulue par deux toiles adjacentes séparées par une glissière intermédiaire.Said guide profile slides in two lateral slides which may also include at least part of the fabric tensioning mechanism. Depending on the dimensions of the surface to be covered, and in order to prevent an excessive deflection of the fabric which could then come into contact with the glazed surface, it may prove necessary to cover the desired glazed surface with two separate adjacent fabrics. by an intermediate slide.

La description qui suit n'est, bien entendu, donnée qu'à titre d'exemple et elle ne vise nullement à limiter la portée de la présente invention qui est déterminée par les revendications.The following description is, of course, given by way of example only and is in no way intended to limit the scope of the present invention which is determined by the claims.

Dans les figures, des repères de référence identiques représentent des éléments identiques ou analogues.In the figures, identical reference marks represent identical or analogous elements.

En référence à la figure 1, on a représenté une construction vitrée du type véranda portant le repère général 1. Le dispositif de protection contre les rayons solaires selon la présente invention 3 est représenté à l'état "détaché" de la construction vitrée 1. Ladite construction se compose de profilés 5 et 7 et de profilés correspondants pour les arêtes et de panneaux translucides 9 agencés de manière étanche sur lesdits profilés 5 et 7.Referring to FIG. 1, a glazed construction of the veranda type is shown bearing the general reference 1. The device for protection against solar rays according to the present invention 3 is shown in the "detached" state from the glazed construction 1. Said construction is made up of profiles 5 and 7 and corresponding profiles for the edges and of translucent panels 9 arranged in a sealed manner on said profiles 5 and 7.

Selon l'invention, le dispositif de protection se compose par exemple de deux toiles 11 et 11', d'un moyen d'enroulement 15 de celles-ci, associé à un mécanisme de tension de ladite toile 11,11', d'un profilé de guidage 20 et de plusieurs glissières latérales ou intermédiaires 25, 27.According to the invention, the protective device consists for example of two fabrics 11 and 11 ', of a winding means 15 thereof, associated with a tensioning mechanism of said fabric 11,11', a guide profile 20 and several lateral or intermediate slides 25, 27.

Dans les figures, on a représenté un dispositif de protection selon l'invention destiné à être monté sur le toit d'une véranda. On peut également prévoir un dispositif analogue destiné à être monté sur les parois latérales verticales ou à l'intérieur de la véranda, par exemple sous le toit de celle-ci ou sur les parois verticales.In the figures, there is shown a protective device according to the invention intended to be mounted on the roof of a veranda. One can also provide a similar device intended to be mounted on the vertical side walls or inside the veranda, for example under the roof thereof or on the vertical walls.

Les figures 2 et 3 représentent deux formes d'exécution de la fixation des glissières intermédiaires 27 à double rainure de guidage sur les profilés 7 qui forment la structure de la véranda. Les glissières latérales 25 sont bien entendu analogues, mais ne comportent qu'une seule rainure de guidage.Figures 2 and 3 show two embodiments of the fixing of the intermediate slides 27 with double guide groove on the profiles 7 which form the structure of the veranda. The side rails 25 are of course similar, but have only one guide groove.

En référence à la figure 2 selon laquelle la construction vitrée se compose de profilés de structure classique 7, en bois, plastique ou métal, sur lesquels reposent éventuellement les panneaux translucides 9 par l'intermédiaire d'un joint 8, la jonction entre deux desdits panneaux étant recouverte par un joint de recouvrement 10, la fixation dudit profilé de glissière 27 (ou 25) s'effectue par l'intermédiaire d'un étrier 12 fixé sur le joint de recouvrement ou directement sur le profil solidaire de deux pattes de fixation et guidage 13, 13' permettant un assemblage réglable transversalement d'un coulisseau 14 auquel peut être adaptée la glissière 27 (ou 25). Un mouvement longitudinal est également possible en faisant glisser une patte de fixation 16 faisant partie de la pièce 14 dans la rainure 17 faisant partie de la pièce 27.Referring to Figure 2 according to which the glazed construction consists of profiles of conventional structure 7, wood, plastic or metal, on which possibly rest the translucent panels 9 via a joint 8, the junction between two of said panels being covered by a cover joint 10, the fixing of said slide profile 27 (or 25) is effected by means of a stirrup 12 fixed on the cover joint or directly on the profile integral with two fixing lugs and guide 13, 13 ′ allowing a transversely adjustable assembly of a slide 14 to which the slide 27 (or 25) can be adapted. Longitudinal movement is also possible by sliding a fixing lug 16 forming part of the part 14 in the groove 17 forming part of the part 27.

En référence à la figure 3, selon laquelle la construction vitrée fait appel à des profilés de structure en T renversé 7 conçus de manière telle que les panneaux 9 reposent sur les bras du T par l'intermédiaire d'un joint 8, la jonction entre deux panneaux adjacents 9 étant recouverte de deux joints de recouvrement partiels, la fixation de la glissière 27 (ou 25) s'effectue par l'intermédiaire d'un étrier 12, monté à cheval et fixé à l'âme du profilé en T 7, ledit étrier 12 étant solidaire de deux pattes de fixation qui permettent, comme dans le cas de la figure 2, un assemblage réglable transversalement du coulisseau 14. Un réglage longitudinal similaire à celui de la figure 2 par les éléments 60 et 61 est également possible.With reference to FIG. 3, according to which the glazed construction uses inverted T structural profiles 7 designed so that the panels 9 rest on the arms of the T via a joint 8, the junction between two adjacent panels 9 being covered with two partial covering joints, the fixing of the slide 27 (or 25) is effected by means of a stirrup 12, mounted astride and fixed to the core of the T-profile 7 , said stirrup 12 being integral with two fixing lugs which allow, as in the case of FIG. 2, an assembly adjustable transversely of the slide 14. A longitudinal adjustment similar to that of FIG. 2 by the elements 60 and 61 is also possible .

Avantageusement, la glissière intermédiaire 27 comporte trois chambres tubulaires dont deux chambres supérieures 29, 30 destinées à recevoir les câbles d'entraînement des toiles disposées de part et d'autre de ladite glissière, et dont une chambre inférieure destinée à recevoir les moyens de fixation de ladite glissière 27 sur les profilés de structure 7, ainsi que deux rainures longitudinales 32 dans lesquelles coulissent les profilés de guidage 20. De manière correspondante, les glissières latérales comportent une chambre 29 pour le câble d'entraînement, une rainure 32 dans laquelle coulisse le profilé de guidage et une chambre inférieure 31.Advantageously, the intermediate slide 27 comprises three tubular chambers including two upper chambers 29, 30 intended to receive the cables for driving the fabrics arranged on either side of said slide, and including a lower chamber intended to receive the fixing means. of said slide 27 on the structural profiles 7, as well as two longitudinal grooves 32 in which the guide profiles slide 20. Correspondingly, the lateral slides have a chamber 29 for the drive cable, a groove 32 in which slides the guide profile and a lower chamber 31.

. Le profilé de guidage 35 est représenté à la figure 5 et se compose d'au moins deux parties, dont une première partie 37 comporte une rainure 39 grâce à laquelle la toile 11, 11' peut y être fixée au moyen d'une barrette, et dont la deuxième partie 41 est détachable et peut être assemblée avec la première partie 35 par emboîtement. Avantageusement, ledit profilé de guidage comporte, à chaque extrémité, un élément coulissant (non représenté) qui sert à faciliter le glissement dudit profilé de guidage 20 dans les glissières 25, 27 et à guider les câbles d'entraînement de la toile.. The guide profile 35 is shown in FIG. 5 and consists of at least two parts, a first part 37 of which has a groove 39 by means of which the fabric 11, 11 ′ can be fixed to it by means of a bar, and the second part 41 of which is detachable and can be assembled with the first part 35 by interlocking. Advantageously, said guide profile comprises, at each end, a sliding element (not shown) which serves to facilitate the sliding of said guide profile 20 in the slides 25, 27 and to guide the drive cables of the fabric.

Tous les profilés susmentionnés sont avantageusement constitués par des profilés en aluminium revêtu; ils peuvent cependant également consister en d'autres matières.All the aforementioned profiles are advantageously constituted by coated aluminum profiles; however, they may also consist of other materials.

Le mécanisme d'enroulement ou de déroulement de la toile 11, 11' est représenté schématiquement à la figure 4. Il consiste par exemple en un arbre 45 entraîné en rotation par au moins un moteur intégré (non représenté). Ledit arbre 45 est muni à chaque extrémité de poulies d'enroulement 47 et 48 des câbles 49 et 50. Le câble d'entraînement 49 ou 50 s'étend de la poulie 47 ou 48 jusqu'à une roulette de renvoi 51 ou 52 montée au niveau de déroulement maximum de la toile, sur laquelle il est dévié d'environ 180° pour rejoindre, via une roulette 53 ou 54, le profilé de guidage 20 dans lequel il est fixé par l'intermédiaire d'un ressort 55.The winding or unwinding mechanism of the fabric 11, 11 ′ is shown diagrammatically in FIG. 4. It consists for example of a shaft 45 driven in rotation by at least one integrated motor (not shown). Said shaft 45 is provided at each end with winding pulleys 47 and 48 of cables 49 and 50. The drive cable 49 or 50 extends from pulley 47 or 48 to a return roller 51 or 52 mounted at the maximum unwinding level of the fabric, on which it is deflected by approximately 180 ° to join, via a roller 53 or 54, the guide profile 20 in which it is fixed by means of a spring 55.

Selon l'invention, le ressort 55 relie deux roulettes 57 et 58 sur lesquelles est dévié le câble avant d'être fixé à l'intérieur du profité 20 en 59 et 60, éventuellement en passant sur au moins une roulette de renvoi supplémentaire (non représentée). Le ressort 55 doit être continuellement sous tension pour que la toile soit toujours tendue et doit être calculé de manière telle qu'il puisse compenser la différence de longueur résultant des variations de diamètre précitées des enroulements respectifs de la toile et des câbles qui exercent une relation contraignante entre le diamètre et la largeur des poulies d'enroulement 47, 48 et le diamètre du câble 49, 50.According to the invention, the spring 55 connects two rollers 57 and 58 on which the cable is deflected before being fixed inside the profit 20 at 59 and 60, possibly passing over at least one additional return roller (not shown). Spring 55 must be continuously tensioned so that the fabric is always taut and must be calculated in such a way that it can compensate for the difference in length resulting from variations of the aforementioned diameter of the respective windings of the fabric and of the cables which exert a binding relationship between the diameter and the width of the winding pulleys 47, 48 and the diameter of the cable 49, 50.

Comme on ne dispose dans le profilé de guidage 20 que d'une longueur réduite pour l'extension du ressort 55 et que, pour une force déterminée, il faut nécessairement un ressort d'une longueur déterminée à l'état sous tension, le montage précité présente l'avantage par rapport aux solutions de l'état de la technique précité de réduire de moitié la course. De ce fait, on obtient une tension plus régulière de la toile depuis la position enroulée jusqu'à la position déroulée.Since there is only a reduced length in the guide profile 20 for the extension of the spring 55 and that, for a determined force, a spring of a determined length is necessarily required in the energized state, the mounting above has the advantage over the aforementioned prior art solutions to reduce the stroke by half. As a result, a more regular tension of the fabric is obtained from the rolled up position to the unrolled position.

Selon l'invention, on a de plus l'avantage que la-forme de construction du profilé de guidage est telle qu'aucune force de traction ou de tension n'est reportée sur la construction portante de la véranda ou analogue (voir figure 6). Ceci résulte du fait que les roulettes de renvoi 51 et 52 et le caisson 71 recevant l'arbre d'enroulement 45 de la toile 11 ou 11' et le dispositif de manoeuvre avec ses fiasques 73 à pivot entrant dans la chambre creuse de la glissière sont portés par les glissières 25, 27 qui elles-mêmes sont calculées pour empêcher une flèche des profilés portants ou des glissières.According to the invention, there is also the advantage that the form of construction of the guide profile is such that no tensile or tensile force is transferred to the supporting construction of the veranda or the like (see FIG. 6 ). This results from the fact that the return rollers 51 and 52 and the box 71 receiving the winding shaft 45 of the fabric 11 or 11 'and the operating device with its flanges 73 pivot entering the hollow chamber of the slide are carried by the slides 25, 27 which themselves are calculated to prevent a deflection of the supporting profiles or the slides.

On constate que le dispositif de l'invention satisfait à un besoin toujours croissant et que les buts énoncés plus haut sont atteints. Le dispositif de l'invention permet de dérouler et d'enrouler une toile sous tension sans que celle-ci ne vienne en contact avec la surface vitrée à couvrir. Par conséquent, la toile ne salit pas, s'use notablement moins vite et n'abîme pas les surfaces à couvrir.It can be seen that the device of the invention meets an ever increasing need and that the aims set out above are achieved. The device of the invention makes it possible to unroll and wind up a fabric under tension without it coming into contact with the glazed surface to be covered. Consequently, the fabric does not get dirty, wears significantly slower and does not damage the surfaces to be covered.
