Description

Store à enrouleur motorisé pour baie galbée Motorized roller blind for curved bay
La présente invention concerne un store à enrouleur motorisé destiné notamment à occulter une baie, en particu¬ lier une baie de véhicule automobile telle qu'une lunette arrière. L'occultation des lunettes arrière de véhicules automobiles est un problème délicat à résoudre étant donné la forme particulièrement complexe d'une telle lunette. En effet, dans certains véhicules, la lunette arrière est très inclinée et galbée avec une courbure en général plus accen- tuée en partie supérieure qu'en partie inférieure. L'occulta¬ tion d'une telle baie est actuellement réalisée au moyen d'un store fixé sous la tablette arrière et déployé jusqu'au bord supérieur de la lunette, le store s'étendant alors dans un plan qui soutend tant bien que mal la surface gauche de la lunette arrière et qui présente l'inconvénient d'être écarté de cette fenêtre notamment à sa base, condamnant ainsi une surface importante de la tablette arrière. En outre, une baie occultée avec un store de ce type ne présente pas une esthétique satisfaisante. On a déjà proposé des stores dans lesquels la toile est courbe du fait même de la forme de la barre de tirage. Cette barre de tirage est généralement courbée pour coïncider avec la courbure supérieure de la fenêtre arrière qui est plus prononcée que la courbure de cette fenêtre au niveau de la tablette arrière. L'enrouleur étant en général situé sous cette tablette, il faut pouvoir disposer notamment aux extrémités latérales de celle-ci d'une largeur suffisante pour pouvoir y dessiner une fente courbe pour accommoder la barre de tirage dans la position enroulée du store. Un tel espace n'est pas toujours disponible sur les tablettes arrière de certains véhicules.The present invention relates to a motorized roller blind intended in particular to obscure a bay, in particular a bay for a motor vehicle such as a rear window. The concealment of the rear glasses of motor vehicles is a delicate problem to be solved given the particularly complex shape of such a window. In fact, in certain vehicles, the rear window is very inclined and curved with a curvature in general more accentuated in the upper part than in the lower part. The occulta¬ tion of such a bay is currently achieved by means of a blind fixed under the rear shelf and deployed to the upper edge of the bezel, the blind then extending in a plane which somehow supports the left surface of the rear window and which has the drawback of being moved away from this window, in particular at its base, thus condemning a large surface of the rear shelf. In addition, a blackout window with a blind of this type does not have a satisfactory aesthetic. We have already proposed blinds in which the fabric is curved due to the very shape of the draw bar. This draw bar is generally curved to coincide with the upper curvature of the rear window which is more pronounced than the curvature of this window at the rear shelf. The roller being generally located under this shelf, it must be possible to have in particular at the lateral ends thereof a sufficient width to be able to draw a curved slot therein to accommodate the pull bar in the rolled position of the blind. Such space is not always available on the rear shelves of certain vehicles.
On rappellera enfin que la motorisation de ce type de store peut être réalisée de plusieurs manières différentes et en particulier grâce à des biellettes déployables confor- mément au document FR-A-2.646.203. Pour pallier les inconvénients des stores existants pour lunette arrière de véhicules automobiles, qui ne peuvent pas être logés dans tous les véhicules d'une part et qui d'autre part n'ont pas de caractère esthétique très satisfai- sant, l'invention propose un store à enrouleur motorisé pour baie galbée permettant d'être situé au plus près de la glace de la baie, en position déployée et pouvant passer au travers d'une fente rectiligne, donc de faible largeur, d'une tablette arrière sous laquelle serait installé le mécanisme d'enroulement.Finally, it will be recalled that the motorization of this type of blind can be achieved in several different ways and in particular by means of deployable rods in accordance with document FR-A-2,646,203. To overcome the drawbacks of existing blinds for rear window of motor vehicles, which cannot be accommodated in all vehicles on the one hand and which on the other hand do not have a very satisfactory aesthetic character, the invention proposes a motorized roller blind for curved bay allowing it to be located as close as possible to the bay window, in the deployed position and which can pass through a rectilinear slot, therefore of small width, of a rear shelf under which would be installed the winding mechanism.
A cet effet l'invention a donc pour objet un store de ce type comportant :To this end the invention therefore relates to a blind of this type comprising:
- un support pour un organe d'enroulement,- a support for a winding member,
- une toile fixée par l'une de ses extrémités à cet organe d'enroulement et par son autre extrémité à une barre de tirage,- a canvas fixed by one of its ends to this winding member and by its other end to a draw bar,
- des moyens de déploiement et reploiement de la toile comportant deux biellettes articulées chacune par une extrémité à la barre de tirage, l'autre extrémité de chaque biellette étant montée articulée coulissante sur une glis¬ sière solidaire du support, sensiblement parallèle à l'axe d'enroulement de la toile et un dispositif d'entraînement synchronisé et en sens opposé du pied coulissant des biellet¬ tes le long de la glissière. Selon l'une des caractéristiques principales de l'invention, la barre de tirage étant élastiquement déforma- ble perpendiculairement à la toile, chaque biellette comporte une base articulée sur le chariot correspondant qui comprend un pivot sur lequel est monté à rotation le corps de bielle pour pouvoir tourner autour de son axe longitudinal par rapport à la base, le corps principal comportant une surface de butée radiale pour entrer au contact d'une surface de butée portée par le chariot lors de la dernière fraction de la course de déploiement du chariot et pour entraîner en pivotement le corps de bielle autour du pivot pendant cette fraction de course. Ainsi, le déploiement de la toile se fait au début dans le plan défini d'une part par la glissière de coulissement des chariots et d'autre part par la barre de tirage poussée par les biellettes, jusqu'au moment où par l'action des butées décrites ci-dessus, on provoque une torsion dans chaque biellette qui entraîne le fléchissement de la barre de tirage car cette torsion entraîne le pivote¬ ment des plans d'articulation des extrémités de cette barre aux biellettes et l'extrémité du store déployé prend un galbe qui peut épouser sensiblement le galbe de la vitre à occul¬ ter.- means for deploying and folding the canvas comprising two links each articulated by one end to the draw bar, the other end of each link being mounted articulated slidingly on a slide secured to the support, substantially parallel to the axis canvas winding and a synchronized drive device and in opposite direction of the sliding foot of the biellet¬ your along the slide. According to one of the main characteristics of the invention, the draw bar being elastically deformable perpendicular to the fabric, each link has a base articulated on the corresponding carriage which comprises a pivot on which the rod body is rotatably mounted in order to be able to rotate about its longitudinal axis with respect to the base, the main body comprising a radial abutment surface for coming into contact with an abutment surface carried by the carriage during the last fraction of the carriage deployment stroke and to pivot the rod body around the pivot during this fraction of race. Thus, the deployment of the fabric is done at the beginning in the plane defined on the one hand by the sliding slide of the carriages and on the other hand by the draw bar pushed by the rods, until by the action of the stops described above, a twist is caused in each link which causes the draw bar to bend because this twist causes the pivoting of the planes of articulation of the ends of this bar to the links and the end of the deployed blind takes a curve which can closely match the curve of the window to be occul¬ ter.
Afin de pouvoir ajuster la valeur de ce galbe ou de ce cintre, la butée par chaque chariot est réglable en position ce qui revient à dire que son contact avec la butée radiale portée par la biellette tournante peut s'opérer plus ou moins tôt dans la course des chariots dans le sens du déploiement du store, et peut donc provoquer un pivotement d'amplitude angulaire plus ou moins important selon le réglage en position de cette butée portée par le chariot. Dans un mode de réalisation préféré de l'invention, cette butée portée par le chariot est constituée par 1'extré¬ mité d'une vis s'étendant parallèlement au plan de débatte¬ ment de la biellette autour de son articulation sur le chariot, cette vis étant logée dans un orifice taraudé prévu dans une paroi du chariot perpendiculaire à ce plan de débattement.In order to be able to adjust the value of this curve or of this hanger, the stopper by each carriage is adjustable in position, which amounts to saying that its contact with the radial stopper carried by the rotary link can occur more or less early in the stroke of the carriages in the direction of deployment of the blind, and can therefore cause a more or less significant angular amplitude pivoting depending on the adjustment in position of this stop carried by the carriage. In a preferred embodiment of the invention, this stop carried by the carriage is constituted by the extremity of a screw extending parallel to the plane of debate of the rod around its articulation on the carriage, this screw being housed in a threaded orifice provided in a wall of the carriage perpendicular to this deflection plane.
D'autres caractéristiques et avantages de l'inven¬ tion ressortiront de la description d'un exemple de réalisa¬ tion qui en est donné ci-après. Pour cette description il sera fait référence au dessin annexé qui par une figure unique représente un store motorisé conforme à l'invention pour baie galbée, dans son état déployé par la demi-vue de gauche de la figure et dans son état enroulé par la demi-vue de droite. Ainsi, le store selon l'invention comporte entre deux flasques support d'extrémité 1 et 2, un enrouleur 3 pour une toile 4, cet enrouleur comportant de manière connue un cylindre auquel une extrémité de la toile 4 est fixée, ac¬ tionné dans le sens de l'enroulement par un dispositif élastique de rappel tel qu'un ressort intérieur. L'autre extrémité de la toile 4, c'est-à-dire son extrémité libre, comporte une barre de tirage 5 suffisamment rigide pour qu'on puisse y atteler, à ses extrémités, des organes de manoeuvre. Entre les deux flasques 1 et 2 on a disposé également une glissière 6 pour deux chariots 7 et 8. Cette glissière 6 forme également un carter pour un dispositif d'entraînement des chariots 7 et 8 le long de la glissière 6, connu en lui-même et comportant par exemple des crémaillères solidaires des chariots et une roue dentée 9 calée sur l'arbre de sortie d'un moteur d'actionnement du store.Other characteristics and advantages of the invention will emerge from the description of an exemplary embodiment which is given below. For this description, reference will be made to the appended drawing which, by a single figure, represents a motorized blind according to the invention for curved bay, in its state deployed by the left half-view of the figure and in its state rolled up by the half -right view. Thus, the blind according to the invention comprises between two end support flanges 1 and 2, a reel 3 for a fabric 4, this reel comprising in a known manner a cylinder to which one end of the fabric 4 is fixed, actuated in the direction of winding by an elastic device return such as an interior spring. The other end of the fabric 4, that is to say its free end, comprises a pulling bar 5 sufficiently rigid so that it can be coupled, at its ends, operating members. Between the two flanges 1 and 2 there is also disposed a slide 6 for two carriages 7 and 8. This slide 6 also forms a casing for a device for driving the carriages 7 and 8 along the slide 6, known in itself- same and comprising for example racks integral with the carriages and a toothed wheel 9 wedged on the output shaft of a motor for actuating the blind.
Chaque chariot comporte une aile inclinée par rapport à la glissière 6 qui porte la référence 10 pour le chariot 7 et la référence 11 pour le chariot 8. Cette aile forme un support d'articulation pour une base 12, 13, cette base étant en forme de chape venant chevaucher le bord courbe des ailes 10 et 11, l'axe d'articulation de chacune de ces bases étant noté 14 et 15.Each carriage has a wing inclined relative to the slide 6 which bears the reference 10 for the carriage 7 and the reference 11 for the carriage 8. This wing forms a hinge support for a base 12, 13, this base being in the form yoke overlapping the curved edge of the wings 10 and 11, the axis of articulation of each of these bases being noted 14 and 15.
A son extrémité opposée aux axes d'articulation 14 et 15, chaque base 12 et 13 comporte, dans le cas de la figure, un manchon 16, 17 formant palier de pivotement pour une tige 18, 19 qui constitue le corps principal de chaque biellette.At its end opposite to the articulation axes 14 and 15, each base 12 and 13 comprises, in the case of the figure, a sleeve 16, 17 forming a pivot bearing for a rod 18, 19 which constitutes the main body of each link .
L'extrémité libre de chaque tige 18, 19 comporte un oeillet 20, 21 entièrement solidaire de la tige correspon- dante 18, 19, permettant l'articulation de chaque tige à 1'extrémité correspondante de la barre de tirage 5.The free end of each rod 18, 19 comprises an eyelet 20, 21 entirely integral with the corresponding rod 18, 19, allowing the articulation of each rod to the corresponding end of the draw bar 5.
Dans le mode de réalisation représenté, chaque manchon 16, 17 solidaire de la pièce de base 12, 13, possède une fente circulaire 22, 23 au travers de laquelle est accessible la tige 18, 19 qui est logée dans le manchon et permettant d'implanter une palette 24, 25 radiale qui forme un organe de manoeuvre de la tige, en rotation autour de son axe longitudinal à 1 'intérieur du manchon en même temps qu'un organe de blocage axial de cette tige par rapport au manchon.In the embodiment shown, each sleeve 16, 17 integral with the base part 12, 13, has a circular slot 22, 23 through which is accessible the rod 18, 19 which is housed in the sleeve and making it possible to install a radial pallet 24, 25 which forms a rod operating member, rotating about its longitudinal axis inside the sleeve at the same time as an axial locking member for this rod relative to the muff.
Chacun des chariots 7 et 8 possède une paroi 26, 27 qui forme un support pour une vis 28, 29 dont l'extrémité se trouve sur l'arc de cercle que décrira la palette 24, 25 lorsque la bielle 18, 19 tournera autour de son axe d'articu- lation 14, 15. Cette vis 28, 29 peut donc faire plus ou moins saillie en direction de la bielle par rapport à la paroi 26, 27 qui la porte, et donc être rencontrée plus ou moins tôt par la palette 24, 25 solidaire de la tige 18, 19.Each of the carriages 7 and 8 has a wall 26, 27 which forms a support for a screw 28, 29 the end of which is on the arc of a circle which will be described by the pallet 24, 25 when the connecting rod 18, 19 turns around its articulation axis 14, 15. This screw 28, 29 can therefore project more or less in the direction of the rod relative to the wall 26, 27 which carries it, and therefore be encountered more or less early by the pallet 24, 25 secured to the rod 18, 19.
Comme dans le document français FR-A-2.646.203 cité en préambule, la roue dentée 9 commande des crémaillères qui sont solidaires des chariots 7 et 8. Quand le store est dans son état reployé, les chariots 7 et 8 sont côte à côte au centre de la glissière 6 et les bielles 18, 19 sont très en biais comme représenté sur la partie de droite de la figure. La commande du déploiement du store par la commande de la roue dentée 9 entraîne 1'écartement l'un de l'autre des chariots 7 et 8 et le redressement progressif des bielles qui repousse la barre de tirage à l'encontre de l'effet de l'organe élastique situé dans le tambour d'enroulement 3. Avant la fin de la course des chariots 7 et 8, la palette 24, 25 rencontre l'extrémité de la vis correspondante 28, 29. Ainsi, pendant la fraction finale de la course des chariots 7 et 8 en direction des flasques support 1 et 2, la vis 28, 29 repousse la palette 24, 25, dans le sens inverse des aiguilles d'une montre autour de l'axe longitudinal de la tige 18 et dans le sens des aiguilles d'une montre autour de l'axe longitudinal de la tige 19. Cette rotation est possible dans le pivot 16, 17 porté par les bagues 12 et 13 et le plan des oeillets 20, 21 n'est plus identique ce qui conduit à faire prendre à la barre de tirage 5 une certaine courbure dont le rayon sera fonction de l'amplitude angulaire de la rotation créée par le contact des vis 28, 29 sur les palettes 24, 25. La barre de tirage se trouve ainsi automatiquement galbée, à même de mieux épouser par exemple le contour supérieur de la vitre que le store est destiné à occulter. Lors du reploiement du store, les chariots 7 et 8 sont entraînés en direction du centre de la glissière 6. Après une fraction faible de cette course de retour, les palettes 24 et 25, du fait de l'inclinaison progressive des tiges 18, 19, quittent le contact des vis 28, 29 et l'élasti¬ cité propre de la barre de tirage ramène les oeillets 20 et 21 sensiblement dans le plan de cette barre de tirage. De ce fait, lorsque le store doit traverser la fente d'une garni¬ ture par exemple d'une tablette arrière sous laquelle il est installé, la barre de tirage est pratiquement rectiligne et la fente peut être de faible largeur donc ne pas nuire a 1'esthétique et à la rigidité de cette tablette arrière de véhicule.As in the French document FR-A-2,646,203 cited in the preamble, the toothed wheel 9 controls racks which are integral with the carriages 7 and 8. When the blind is in its folded state, the carriages 7 and 8 are side by side in the center of the slide 6 and the connecting rods 18, 19 are very oblique as shown in the right part of the figure. The control of the deployment of the blind by the control of the toothed wheel 9 causes the carriages 7 and 8 to move apart from one another and the progressive straightening of the connecting rods which pushes the draw bar against the effect of the elastic member located in the winding drum 3. Before the end of the carriage 7 and 8, the pallet 24, 25 meets the end of the corresponding screw 28, 29. Thus, during the final fraction of the stroke of the carriages 7 and 8 in the direction of the support flanges 1 and 2, the screw 28, 29 pushes the pallet 24, 25 counterclockwise around the longitudinal axis of the rod 18 and in clockwise around the longitudinal axis of the rod 19. This rotation is possible in the pivot 16, 17 carried by the rings 12 and 13 and the plane of the eyelets 20, 21 is no longer identical this which leads to the draw bar 5 taking a certain curvature whose radius will be a function of the angular amplitude of the rotation created by the contact of the screws 28, 29 on the pallets 24, 25. The draw bar is thus automatically curved, able to better match, for example the upper contour of the window that the blind is intended to obscure. When the blind is folded back, the carriages 7 and 8 are driven towards the center of the slide 6. After a small fraction of this return stroke, the pallets 24 and 25, due to the progressive inclination of the rods 18, 19 , leave the contact of the screws 28, 29 and the own elasticity of the draw bar brings the eyelets 20 and 21 substantially in the plane of this draw bar. Therefore, when the blind must cross the slot of a garni¬ ture for example of a rear shelf under which it is installed, the pull bar is practically straight and the slot can be narrow so do not harm The aesthetics and rigidity of this rear vehicle shelf.
Le mode de réalisation de 1'invention tel que représenté à la figure n'est pas limitatif et on peut imaginer d'autres moyens pour provoquer à la fin de la course des chariots lors du déploiement du store, la rotation des tiges 18, 19 : par exemple un secteur denté solidaire des tiges 18, 19 coopérant avec une crémaillère solidaire des ailes inclinées 10, 11 des chariots. The embodiment of the invention as shown in the figure is not limiting and one can imagine other means for causing the rotation of the rods 18, 19 at the end of the carriage stroke when the blind is deployed. : for example a toothed sector integral with the rods 18, 19 cooperating with a rack integral with the inclined wings 10, 11 of the carriages.
