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 pourvues à chacune de leur extrémité latérale de 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 des rails de guidage dans lesquels glissent les extrémités latérales des lames du tablier.The invention relates to a device for driving a roller shutter, the deck of which moves at a slight inclination and comprising a shaft for winding and / or unwinding the deck formed by blades provided at each of their lateral ends with means of gripping 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 side flanges of a box on which abut guide rails in which the lateral ends of the deck blades slide.

On connaît déjà, 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.EP-A-0 145 628 already discloses a device for driving a rolling shutter for glass verandah roofs, roof skylights 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 whose teeth 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 depending on 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 apron 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 fines lames à double paroi 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 fines lames à double paroi ou de lames à simple paroi.However, this known device has a certain number of drawbacks, in particular it cannot be used for roller shutters whose deck is formed from thin double-walled blades or from single-walled blades. Indeed, it is necessary that the nipples of grip include 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 disengagement of the latter with respect to to 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 apron and would lose the advantage of using thin double-walled blades or single-walled 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 fines lames à double paroi ou de lames à simple paroi.The present invention aims to remedy these drawbacks and proposes to provide a device for driving an apron of a roller shutter consisting of thin double-walled blades or single-walled blades.

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 pourvues à chacune de leur extrémité latérale de 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 des rails de guidage dans lesquels glissent les extrémités latérales des lames du tablier, dont les moyens de préhension sont des lumières réalisées aux extrémités latérales des fines lames à double paroi ou des lames à simple paroi dont est formé le tablier et pourvues de renforts présentant au moins une lumière, située au droit de la lumière des lames et coopérant avec les dents des roues à cames du second arbre d'entraînement.The invention, as characterized in the claims, solves the problem of creating a device for driving a rolling shutter whose deck moves at a slight inclination and comprising a winding shaft and / or unwinding of the apron formed of blades provided at each of their lateral ends with 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 by relative to the winding and / or unwinding shaft, these shafts being held by lateral flanges of a box on which abut guide rails in which the lateral ends of the deck slats slide, the gripping means of which are lights made at the lateral ends of the thin double-walled blades or single-walled blades from which the apron is formed and provided with reinforcements having at least one lumen, located in line with the lumen of the blades and cooperating with the teeth of the cam wheels of the second drive shaft.

Les avantages obtenus grâce à cette invention consistent essentiellement en ceci qu'il est possible d'utiliser pour la réalisation du tablier des fines lames à double paroi ou des lames à simple paroi et, de ce fait, réduire le diamètre d'enroulement dudit tablier. Ainsi, en réduisant ce diamètre d'enroulement, il est possible de réduire la section du caisson et de pourvoir, notamment, les fenêtres de toiture d'un volet roulant sans déparer l'esthétique de ces fenêtres de toiture. Par ailleurs, on diminue la formation de congères à la partie supérieure de la fenêtre de toiture pourvue d'un caisson de hauteur rapetissée.The advantages obtained thanks to this invention consist essentially in the fact that it is possible to use for the production of the apron thin double-walled blades or single-walled blades and, therefore, reduce the winding diameter of said apron . By reducing this winding diameter, it is possible to reduce the section of the box and to provide, in particular, the roof windows with a shutter without spoiling the aesthetics of these roof windows. Furthermore, the formation of snowdrifts is reduced at the upper part of the roof window provided with a box of reduced height.

L'invention est exposée ci-après plus en détail à l'aide de dessins représentant seulement des modes d'exécution.The invention is set out below in more detail with the aid of drawings representing only embodiments.

La figure 1 représente, en vue en perspective, l'une des extrémités latérales de l'extrémité supérieure d'un volet roulant comportant le dispositif d'entraînement conforme à l'invention.FIG. 1 shows, in perspective view, one of the lateral ends of the upper end of a rolling shutter comprising the drive device according to the invention.

La figure 5 représente, en vue en élévation, la coopération de la lame à simple paroi pourvue du cavalier avec la roue à came de l'arbre d'entraînement.FIG. 5 shows, in elevation view, the cooperation of the single-walled blade provided with the jumper with the cam wheel of the drive shaft.

On se réfère à la figure 1.We refer to figure 1.

Conformément à l'invention, le volet roulant 1, destiné à équiper les toits de vérandas, les lucarnes de toiture et autres et, en général, les ouvertures présentant une faible inclinaison ou une inclinaison nulle telles que le dessus de piscines privées, comporte un tablier 2, composé de fines lames à double paroi 3 (voir figure 2) ou de lames à simple paroi 4 (voir figure 4). Ce tablier 2 s'enroule ou se déroule d'un arbre d'enroulement et/ou de déroulement 5 et il est actionné par un second arbre d'entraînement 6 disposé en aval par rapport à l'arbre d'enroulement et/ou de déroulement 5. Ces arbres 5, 6 sont maintenus par des flasques latéraux 7 d'un caisson (non représenté) sur lequel aboutent des rails de guidage 8 dans lesquels glissent les extrémités latérales 9, 10 des lames 3 ou 4.According to the invention, the roller shutter 1, intended to equip the roofs of verandas, the roof dormers and the like and, in general, the openings having a low inclination or a zero inclination such as the top of private swimming pools, comprises a deck 2, made up of thin double-walled blades 3 (see Figure 2) or single-walled blades 4 (see Figure 4). This apron 2 is wound or unwound from a winding and / or unwinding shaft 5 and it is actuated by a second drive shaft 6 disposed downstream relative to the winding shaft and / or unwinding 5. These shafts 5, 6 are held by lateral flanges 7 of a box (not shown) on which abut guide rails 8 in which the lateral ends 9, 10 of the blades 3 or 4 slide.

Le second arbre d'entraînement 6 comporte, à chacune de ses extrémités 11, une roue à cames 12 coopérant avec des moyens de préhension 13 dont sont pourvues les lames 3 ou 4.The second drive shaft 6 comprises, at each of its ends 11, a cam wheel 12 cooperating with gripping means 13 with which the blades 3 or 4 are provided.

En utilisant de telles lames 3 ou 4 pour la réalisation du tablier 2, on peut diminuer considérablement le diamètre d'enroulement de ce tablier 2 et, par voie de conséquence, la section du caisson, ce qui permet une plus grande utilisation du volet roulant, notamment lorsqu'il y a limitation de la place disponible rendant impossible la mise en place d'un volet roulant pourvu d'un caisson de section normale.By using such blades 3 or 4 for the production of the deck 2, it is possible to considerably reduce the winding diameter of this deck 2 and, consequently, the section of the box, which allows greater use of the shutter , especially when there is limitation of the space available making it impossible to install a roller shutter provided with a box of normal section.

Toutefois, pour un tel tablier 2 formé de lames 3 ou 4 ayant une épaisseur de l'ordre de deux à trois millimètres, on ne peut pas utiliser les moyens de préhension connus constitués par des tétons faisant saillie latéralement et coopérant avec les roues à cames 12 du second arbre d'entraînement 6.However, for such an apron 2 formed of blades 3 or 4 having a thickness of the order of two to three millimeters, it is not possible to use the known gripping means constituted by pins projecting laterally and cooperating with the cam wheels 12 of the second drive shaft 6.

Conformément à l'invention, les moyens de préhension 13 sont constitués par des lumières 14 traversant de part en part le dos 15 des lames 3 ou 4. Ces lumières 14 sont disposées aux extrémités latérales 9, 10 des lames 3 ou 4. Dans ces lumières 14 s'engagent les dents 16, 17 des roues à cames 12.According to the invention, the gripping means 13 are constituted by slots 14 passing right through the back 15 of the blades 3 or 4. These slots 14 are arranged at the lateral ends 9, 10 of the blades 3 or 4. In these lights 14 engage the teeth 16, 17 of the cam wheels 12.

Cependant, en raison de la fragilité des lames 3 ou 4, les dents 16, 17 des roues à cames 12 ne prennent pas appui contre les chants avant 18 ou arrière 19 des lumières 14 mais coopèrent avec des renforts.However, due to the fragility of the blades 3 or 4, the teeth 16, 17 of the cam wheels 12 do not bear against the front edges 18 or rear 19 of the slots 14 but cooperate with reinforcements.

Selon un premier mode de réalisation, ces renforts sont un insert 20 que l'on enfile dans le chant latéral 21 de la fine lame à double paroi 3. Le chant avant 22 et le chant arrière 23 de cet insert 20 viennent en butée contre la paroi avant 24 et la paroi arrière 25 de la lame 3. Ledit insert 20 comporte également une lumière 26 située, après mise en place de celui-ci dans la lame 3, dans le même plan que la lumière 14 de la lame 3. Cette lumière 26 présente un rebord périphérique saillant 27 épousant les chants 28, 29, 30, 31 tant des lumières 14₁ que des lumières 14₂ réalisées respectivement dans la paroi interne 32 et la paroi externe 33 du dos 15 de la lame 3. La hauteur 34 de ce rebord périphérique saillant 27 est égale ou légèrement inférieure à l'épaisseur 35 de la lame 3 de sorte que ce rebord périphérique 27 ne fasse pas saillie par rapport à la face externe 36, 37 des parois interne 32 et externe 33 du dos 15 de la lame 3. La mise en place de cet insert 20 se fait par clipage, ce clipage étant possible en raison de l'élasticité des parois interne 32 et externe 33 due à la faible épaisseur de ces dernières.According to a first embodiment, these reinforcements are an insert 20 which is threaded into the lateral edge 21 of the thin double-walled blade 3. The front edge 22 and the rear edge 23 of this insert 20 abut against the front wall 24 and rear wall 25 of the blade 3. Said insert 20 also includes a lumen 26 located, after positioning of the latter in the blade 3, in the same plane as the lumen 14 of the blade 3. This light 26 has a protruding peripheral edge 27 matching the edges 28, 29, 30, 31 both lights 14 tant and lights 14₂ produced respectively in the inner wall 32 and the outer wall 33 of the back 15 of the blade 3. The height 34 of this projecting peripheral rim 27 is equal to or slightly less than the thickness 35 of the blade 3 so that this peripheral rim 27 does not projection relative to the external face 36, 37 of the internal 32 and external 33 walls of the back 15 of the blade 3. The insertion of this insert 20 is by clipping, this clipping being possible due to the elasticity of the walls internal 32 and external 33 due to the small thickness of the latter.

Selon un autre mode de réalisation, ces renforts sont un cavalier 38 enjambant le chant latéral 39 de la lame à simple paroi 4, de sorte que les deux ailes parallèles 40, 41 de ce cavalier 38 viennent s'appliquer contre la face interne 42 et externe 43 de la lame 4. Ces deux ailes parallèles 40, 41 comportent des lumières 44, 45 qui, après montage, sont situées dans le même plan que la lumière 14 de la lame 4. On pourvoit les lumières 44, 45 d'un rebord périphérique saillant vers l'intérieur 46, 47 venant s'encliqueter dans la lumière 14 de la lame 4. La somme des hauteurs de ces rebords périphériques 46, 47 est légèrement inférieure à l'épaisseur de la paroi de la lame 4. Ledit cavalier 38 est rendu solidaire de la lame 4 par encliquetage des rebords périphériques 46, 47 dans la lumière 14 de la lame 4.According to another embodiment, these reinforcements are a jumper 38 spanning the lateral edge 39 of the single-walled blade 4, so that the two parallel wings 40, 41 of this jumper 38 come to bear against the internal face 42 and outer 43 of the blade 4. These two parallel wings 40, 41 have slots 44, 45 which, after assembly, are located in the same plane as the slot 14 of the blade 4. The slots 44, 45 are provided with a peripheral edge projecting inwards 46, 47 snapping into the lumen 14 of the blade 4. The sum of the heights of these peripheral edges 46, 47 is slightly less than the thickness of the wall of the blade 4. Said jumper 38 is made integral with the blade 4 by snap-fastening of the peripheral edges 46, 47 in the lumen 14 of the blade 4.

A cet effet, le cavalier 38 est réalisé en un matériau élastique formant ressort assurant le rapprochement élastique des ailes parallèles 40, 41 après leur écartement nécessaire à la mise en place du cavalier 38. L'utilisation de ce dernier n'augmente en rien le diamètre d'enroulement du tablier car la somme des épaisseurs du cavalier 38 et de la lame à simple paroi 4 n'est pas supérieure à l'épaisseur de deux à trois millimètres de la lame fine 3.For this purpose, the jumper 38 is made of an elastic material forming a spring ensuring the elastic approximation of the parallel wings 40, 41 after their spacing necessary for the installation of the jumper 38. The use of the latter does not in any way increase the apron winding diameter because the sum of the thicknesses of the rider 38 and the single-walled blade 4 is not greater than the thickness of two to three millimeters of the thin blade 3.
