Description
L'invention concerne un dispositif d'entraînement d'un volet roulant dont le tablier se déplace selon une faible inclinaison et comprenant un arbre d'enroulement et/ou de déroulement du tablier formé de lames fines pourvues à chacune de leurs extrémités latérales de moyens de préhension formés par des lumières réalisées dans lesdites extrémités latérales et pourvues de renfort constitué d'un insert introduit latéralement dans le chant de la lame fine et présentant également une lumière située au droit des lumières des lames fines, ces moyens de préhension coopérant avec des roues à cames présentant une course à vide entre chaque dent et placées à chacune des extrémités latérales d'un second arbre d'entraînement disposé en aval par rapport à l'arbre d'enroulement et/ou de déroulement, ces arbres étant maintenus par des flasques latéraux d'un caisson sur lequel aboutent les rails de guidage dans lesquels glissent les extrémités latérales des lames fines du tablier.The invention relates to a device for driving a rolling shutter, the apron of which moves at a slight inclination and comprising a shaft for winding and / or unwinding the apron formed from thin blades provided at each of their lateral ends with means. gripping formed by lights made in said lateral ends and provided with reinforcement consisting of an insert inserted laterally into the edge of the thin blade and also having a light located in line with the lights of the thin blades, these gripping means cooperating with cam wheels having an idle stroke between each tooth and placed at each of the lateral ends of a second drive shaft disposed downstream relative to the winding and / or unwinding shaft, these shafts being held by lateral flanges of a box on which abut the guide rails in which the lateral ends of the blades slide s fine apron.
On connaît déjà par le document EP-A-0.317.461 un dispositif d'entraînement d'un volet roulant correspondant au préambule de la revendication 1.Document EP-A-0.317.461 already discloses a device for driving a rolling shutter corresponding to the preamble of claim 1.
Toutefois, les différentes lames du tablier sont reliées entre elles par des articulations télescopiques pour, d'une part, assurer une certaine rotation d'une lame par rapport à sa voisine pour permettre l'enroulement (ou le déroulement du tablier) sur (de) l'arbre d'enroulement et/ou de déroulement et, d'autre part, faciliter un certain déplacement des lames par rapport à leur axe longitudinal pour libérer les jours réalisés dans la tête de la lame. Cette dernière comporte une lèvre repliée en forme de crochet que l'on enfile latéralement dans le talon de la lame suivante, ce talon présentant une gouttière ouverte vers le bas et solidaire de la paroi avant de la lame fine et un crochet orienté vers l'espace interne de la gouttière et solidaire de la paroi arrière de la lame fine.However, the various blades of the deck are connected together by telescopic joints to, on the one hand, ensure a certain rotation of a blade relative to its neighbor to allow winding (or unwinding of the deck) on (de ) the winding and / or unwinding shaft and, on the other hand, facilitate a certain displacement of the blades relative to their longitudinal axis to free the days made in the head of the blade. The latter has a folded lip in the form of a hook which is threaded laterally into the heel of the next blade, this heel having a gutter open downwards and integral with the front wall of the thin blade and a hook oriented towards the internal space of the gutter and integral with the rear wall of the thin blade.
En position ajourée, la pluie et la neige pénètrent à travers ces jours dans les articulations distendues et, en cas de gel, les articulations sont bloquées par la glace. Sachant que la glace permet, malgré sa présence, le pivotement d'une lame par rapport à l'autre et qu'elle empêche tout rapprochement ou écartement de deux lames consécutives, il s'avère souhaitable de diminuer, au point de rotation, le volume de glace.In the open position, rain and snow penetrate through these days into the distended joints and, in the event of frost, the joints are blocked by ice. Knowing that the glass allows, despite its presence, the pivoting of one blade relative to the other and that it prevents all approximation or separation of two consecutive blades, it is desirable to reduce, at the point of rotation, the volume of ice.
Par ailleurs, on connait par le document EP-A-0.145.628 un dispositif d'entraînement d'un volet roulant pour toits de vérandas en verre, lucarnes de toiture et autres dont le tablier se déplace selon une faible inclinaison. Ce dispositif comprend un arbre d'enroulement et/ou de déroulement dudit tablier. Ce dernier est formé de lames enfilées latéralement et reliées entre elles par une articulation. Chaque lame est pourvue, à chacune de ses extrémités, de moyens de préhension constitués d'un téton unique faisant saillie par rapport aux chants latéraux des lames. Ces moyens de préhension coopèrent avec des roues à cames dont les dents présentent des flancs constitués d'une développante de cercle. Ces roues à cames comportent, entre chaque dent, une course à vide pour absorber la variation de la distance entre deux tétons consécutifs en fonction du mouvement du tablier. Ces roues à cames sont disposées à chacune des extrémités d'un second arbre d'entraînement et sont solidaires en rotation de ce dernier, ce second arbre d'entraînement étant disposé en aval par rapport à l'arbre d'enroulement et/ou de déroulement. Ces arbres sont maintenus par des flasques latéraux d'un caisson dans lequel s'enroule et duquel se déroule le tablier dont les extrémités latérales des lames coulissent dans des rails de guidage solidaires du caisson.Furthermore, document EP-A-0.145.628 discloses a device for driving a rolling shutter for glass verandah roofs, roof dormers and the like whose deck moves at a slight inclination. This device comprises a winding and / or unwinding shaft for said deck. The latter is formed of blades threaded laterally and connected together by a joint. Each blade is provided, at each of its ends, with gripping means constituted by a single stud projecting from the lateral edges of the blades. These gripping means cooperate with cam wheels, the teeth of which have flanks consisting of an involute of a circle. These cam wheels have, between each tooth, an idle stroke to absorb the variation in the distance between two consecutive pins according to the movement of the deck. These cam wheels are arranged at each end of a second drive shaft and are integral in rotation with the latter, this second drive shaft being arranged downstream relative to the winding shaft and / or unfolding. These shafts are held in place by lateral flanges of a box in which the deck is rolled up and unrolled, the lateral ends of the blades of which slide in guide rails integral with the box.
Toutefois, ce dispositif connu présente un certain nombre d'inconvénients, notamment il ne peut être utilisé pour des volets roulants dont le tablier est formé de lames fines ou de lames à simple paroi. En effet, il est nécessaire que les tétons de préhension comportent une résistance supérieure au couple du moteur électrique actionnant l'arbre d'entraînement pour transmettre tout blocage du tablier aux roues à cames et, par voie de conséquence. à l'arbre d'entraînement pour provoquer le débrayage de ce dernier par rapport au moteur électrique. Cette résistance ne peut être obtenue qu'en conférant aux tétons un diamètre relativement important ce qui augmenterait automatiquement le diamètre d'enroulement du tablier et ferait perdre l'avantage de l'utilisation de lames fines.However, this known device has a certain number of drawbacks, in particular it cannot be used for roller shutters the deck of which is formed from thin blades or single-walled blades. Indeed, it is necessary that the gripping pins have a resistance greater than the torque of the electric motor actuating the drive shaft to transmit any blocking of the apron to the cam wheels and, consequently. to the drive shaft to cause the latter to disengage from the electric motor. This resistance can only be obtained by giving the nipples a relatively large diameter which would automatically increase the winding diameter of the deck and would lose the advantage of using thin blades.
La présente invention a pour but de remédier à ces inconvénients et se propose de fournir un dispositif d'entraînement d'un tablier de volet roulant constitué de lames fines dont le déplacement d'une lame fine par rapport à sa voisine est condamné.The object of the present invention is to remedy these drawbacks and proposes to provide a device for driving an apron of a roller shutter made up of thin blades whose movement of a thin blade relative to its neighbor is condemned.
L'invention telle qu'elle est caractérisée dans les revendications résout le problème consistant à créer un dispositif d'entraînement d'un volet roulant dont le tablier se déplace selon une faible inclinaison et comprenant un arbre d'enroulement et/ou de déroulement du tablier formé de lames fines pourvues à chacune de leurs extrémités latérales de moyens de préhension formés par les lumières réalisées dans lesdites extrémités latérales et pourvues de renfort constitué d'un insert introduit latéralement dans le chant de la lame fine et présentant également une lumière située au droit des lumières des lames fines, ces moyens de préhension coopérant avec des roues à cames présentant une course à vide entre chaque dent et placées à chacune des extrémités latérales d'un second arbre d'entraînement disposé en aval par rapport à l'arbre d'enroulement et/ou de déroulement, ces arbres étant maintenus par des flasques latéraux d'un caisson sur lequel aboutent les rails de guidage dans lesquels glissent les extrémités latérales des lames fines du tablier dont l'insert comporte, du côté de son chant dirigé vers le talon de la lame fine des moyens s'engageant dans la gouttière de ladite lame fine et condamnant tout déplacement des lames fines par rapport à leur axe longitudinal.The invention as characterized in the claims solves the problem of creating a drive device for a roller shutter, the deck of which moves at a slight inclination and comprising a winding and / or unwinding shaft. apron formed of thin blades provided at each of their lateral ends with gripping means formed by the openings made in said lateral ends and provided with reinforcement consisting of an insert inserted laterally into the edge of the thin blade and also having a light located at the right of the lights of the thin blades, these gripping means cooperating with cam wheels having an idle stroke between each tooth and placed at each of the lateral ends of a second drive shaft disposed downstream relative to the shaft d winding and / or unwinding, these shafts being held by lateral flanges of a box on which abut the guide rails in which the lateral ends of the thin blades of the deck slide, the insert of which, on the side of its edge directed towards the heel of the thin blade, means engaging in the gutter of said thin blade and condemning any movement of the thin blades relative to their longitudinal axis.
Les avantages obtenus grâce à cette invention consistent essentiellement en ce que, grâce aux moyens de condamnation conférés à l'insert, on maintien un contact constant entre la face active du crochet orienté vers l'espace interne de la gouttière du talon de la lame en amont avec la face active de la lèvre en forme de crochet de la tête de la lame en aval. De ce fait, la rotation d'une lame fine par rapport à sa voisine qui permet, en temps de gel, d'assurer l'enroulement et/ou le déroulement du tablier sur l'arbre d'enroulement et/ou de déroulement et ainsi de pouvoir utiliser en hiver le volet roulant pour obturer les fenêtres de toits, toits de vérandas et analogues.The advantages obtained thanks to this invention essentially consist in that, thanks to the locking means imparted to the insert, a constant contact is maintained between the active face of the hook oriented towards the internal space of the gutter of the heel of the blade. upstream with the active face of the hook-shaped lip of the head of the blade downstream. Therefore, the rotation of a thin blade relative to its neighbor which allows, in frost, to ensure the winding and / or unwinding of the deck on the winding and / or unwinding shaft and thus being able to use the roller shutter in winter for closing roof windows, verandah roofs and the like.

On se réfère aux différentes figures.We refer to the different figures.
Le volet roulant 1 comporte un tablier 2 se déplaçant selon une faible inclinaison et s'enroulant ou se déroulant d'un arbre d'enroulement et/ou de déroulement 3. Ce tablier 2 est constitué de lames fines 4, 5, 6 reliées entre elles par des articulations télescopiques 7, 8, 9. Ces lames fines 4, 5, 6 sont formées d'une paroi avant 10 et d'une paroi arrière 11. Les parois avant 10 et arrière 11 sont reliées entre elles par une tête 12 comportant une lèvre 13 repliée en forme de crochet. A sa partie inférieure, la lame fine 4, 5, 6 comporte un talon 15. Ce talon 15 présente une gouttière 16 ouverte vers le bas et solidaire de la paroi avant 10 et un crochet 17 orienté vers l'espace interne 18 de la gouttière 16 et solidaire de la paroi arrière 11 de la lame fine 4, 5, 6.The roller shutter 1 comprises an
Pour la réalisation du tablier 2, on enfile latéralement la tête 12 de la lame fine en aval 6 dans le talon 15 de la lame fine en amont 5, de sorte que la face active 19 de la lèvre 13 de la lame fine en aval 6 vient s'accrocher à la face active 20 du crochet 17 du talon 15 de la lame fine en amont 5. La liaison entre les deux lames fines 5, 6, constitue l'articulation 7, 8, 9 permettant à l'une des lames fines 5 de pivoter par rapport à la lame fine voisine 6 pour permettre l'enroulement du tablier 2 sur l'arbre d'enroulement et/ou de déroulement 3. La course télescopique des articulations 7, 8, 9 est fonction de la hauteur 21 de la tête 12 et de la profondeur 22 de la gouttière 16.For the production of the
Chaque lame fine 4, 5, 6, est pourvue à chacune de ses extrémités latérales 23, 24, 25 de moyens de préhension constitués par des lumières 26, 27, 28 réalisées dans lesdites extrémités latérales 23, 24, 25 et traversant de part en part, la lame fine 4, 5, 6. En raison de leur faible épaisseur, on introduit latéralement dans les lames fines 4, 5, 6, des renforts formés d'inserts 29, 30, 31. Dans ces inserts 29, 30, 31 sont pratiquées des lumières 32, 33, 34 qui, après mise en place de ces inserts 29, 30, 31 dans les lames fines 4, 5, 6, sont dans le même alignement que les lumières 26, 27, 28 de ces dernières.Each
Le chant supérieur 35 des inserts 29, 30, 31 vient en butée contre la tête 12 alors que le chant inférieur 36 vient en butée contre le fond 37 de la gouttière 16.The
Les lumières 26, 27, 28 et 32, 33, 34 coopèrent avec des dents 38, 39 d'une roue à cames 40 placée à chacune des extrémités 41 d'un arbre d'entraînement 42 disposé en aval par rapport à l'arbre d'enroulement et/ou de déroulement 3. Cet arbre d'entraînement 42 exerce une poussée sur le tablier 2 pour le déploiement de ce dernier.The
L'arbre d'enroulement et/ou de déroulement 3 et l'arbre d'entraînement 42 sont maintenus par des flasques latéraux 43 d'un caisson 44 sur lequel aboutent des rails de guidage 45 dans lesquels glissent les extrémités latérales 23, 24, 25 des lames fines 4, 5, 6.The winding and / or unwinding shaft 3 and the
Selon l'invention, on veut obtenir un contact constant entre la face active 19 de la lèvre 13 de la tête 12 de la lame fine en aval 4, 5, 6 avec la face active 20 du crochet 17 du talon 15 de la lame fine en amont 4, 5, 6 pour permettre la rotation d'une lèvre fine 4, 5, 6 par rapport à sa voisine, malgré la présence de glace dans les articulations 7, 8, 9. Il y a donc lieu de condamner la course télescopique desdites articulations 7, 8, 9.According to the invention, it is desired to obtain constant contact between the
A cet effet, on pourvoit les inserts 29, 30, 31 de moyens 46 condamnant tout déplacement des lames fines 4, 5, 6 par rapport à leur axe longitudinal 47.
