Description

La présente invention concerne un dispositif d'entraînement pour système de fermeture de bâtiment de type volet roulant, porte de garage ou similaire, comportant un moteur coopérant avec des moyens d'entraînement aptes à actionner le système de fermeture.The present invention relates to a drive device for a building closure system type shutter, garage door or the like, comprising a motor cooperating with drive means able to actuate the closure system.

La présente invention entre dans le domaine des dispositifs d'entraînement de systèmes de fermeture de bâtiment tel que volet roulant, porte de garage basculante, sectionnelle, pliable ou analogue.The present invention is in the field of driving devices of building closure systems such as roller shutter, garage door tilting, sectional, folding or the like.

Les dispositifs d'entraînement selon WO 01/55548 A et DE 2325755 A1 sont pertinents.The training devices according to WO 01/55548 A and DE 2325755 A1 are relevant.

Si on prend l'exemple d'un volet roulant, celui-ci est constitué d'un tablier, composé de lames juxtaposées et articulées entre elles, et qui peut passer d'une position déployée de fermeture à une position d'ouverture où il vient s'enrouler autour d'un tube d'enroulement. Le passage d'une position à une autre s'effectue sous l'action de moyens d'entraînement, notamment un moteur tubulaire de type électrique qui peut être inséré à l'intérieur dudit tube d'enroulement.If we take the example of a roller shutter, it consists of an apron, composed of juxtaposed blades and hinged together, and which can move from an extended position of closure to an open position where it is wrapped around a winding tube. The passage from one position to another takes place under the action of drive means, in particular an electric type tubular motor that can be inserted inside said winding tube.

Très généralement, un tel moteur agit au travers d'un réducteur sur le tube d'enroulement. Il comporte par ailleurs un frein électromagnétique intégré, fonctionnant par manque de courant. En somme, celui-ci empêche la rotation du moteur et, par voie de conséquence, celle du tube d'enroulement lorsque l'alimentation en énergie électrique est coupée. De cette manière on empêche l'ouverture depuis l'extérieur du tablier par action directe sur ce dernier lorsque le volet roulant se trouve en position déployée de fermeture, tout comme un tel frein électromagnétique peut interdire l'ouverture d'un ouvrant de porte de garage ou de tout autre système de fermeture de bâtiment.Very generally, such a motor acts through a gearbox on the winding tube. It also includes an integrated electromagnetic brake, operating by lack of current. In short, it prevents rotation of the motor and, consequently, that of the winding tube when the power supply is cut off. In this way it prevents the opening from outside the deck by direct action on the latter when the shutter is in the extended position of closure, just as such an electromagnetic brake can prohibit the opening of a door opening door. garage or any other building closure system.

Un inconvénient apparaît sur ces dispositifs d'entraînement lorsqu'un problème survient au niveau du moteur ou tout simplement en cas de coupure de son alimentation électrique. En effet, dans la mesure où le frein est activé, il ne permet plus de manoeuvrer le volet roulant, la porte de garage ou tout autre dispositif de fermeture.A disadvantage appears on these drive devices when a problem occurs in the engine or any simply in case of power failure. Indeed, insofar as the brake is activated, it no longer allows to operate the shutter, the garage door or any other closure device.

Pour pallier ce problème, l'état de la technique prévoie déjà d'incorporer à un tel volet roulant ou similaire une manoeuvre de secours, généralement activée manuellement et autorisant les commandes d'ouverture et de fermeture.To alleviate this problem, the state of the art already provides for incorporating such a roller shutter or the like into an emergency maneuver, generally activated manually and allowing the opening and closing commands.

A titre d'exemple dans le cas particulier d'un volet roulant, une telle manoeuvre de secours peut comporter une poulie ou un treuil dont est dépendant la tête du moteur tubulaire engagé dans le tube d'enroulement du tablier de ce volet roulant. Une telle solution nécessite de mettre en oeuvre une connexion électrique rotative autorisant cette rotation complète du bloc moteur par rapport à son raccordement au réseau d'alimentation en énergie électrique.As an example in the particular case of a roller shutter, such an emergency maneuver can comprise a pulley or a winch which is dependent on the head of the tubular motor engaged in the winding tube of the deck of the shutter. Such a solution requires implementing a rotary electrical connection allowing this complete rotation of the motor unit relative to its connection to the power supply network.

D'autres solutions au moins aussi complexes assurent une fonction de débrayage entre le moteur et ledit tube d'enroulement. En d'autres termes, on vient déconnecter le moteur avec son frein intégré d'un réducteur au travers duquel il agit sur le tube d'enroulement. L'action du frein étant de ce fait annihilé, il est possible de manoeuvrer par action directe le tablier du volet roulant. Toutefois, en raison du poids du tablier d'un tel volet roulant, il peut être utile d'assurer, là encore, cette manoeuvre au travers d'un mécanisme d'entraînement manuel, par exemple un treuil ou une poulie. L'action de ce mécanisme d'entraînement manuel est alors répercutée sur le tube d'enroulement du tablier au travers dudit réducteur qui rend malheureusement la manoeuvre lente, voire pénible.Other solutions at least as complex provide a disengagement function between the motor and said winding tube. In other words, it disconnects the motor with its built-in brake gearbox through which it acts on the winding tube. The action of the brake being thereby annihilated, it is possible to maneuver by direct action the apron of the roller shutter. However, because of the weight of the deck of such a shutter, it may be useful to ensure, again, this maneuver through a manual drive mechanism, for example a winch or a pulley. The action of this manual drive mechanism is then reflected on the winding tube of the deck through said gear which unfortunately makes the maneuver slow, even painful.

On comprend, évidemment, que ces solutions sont complexes, difficiles à mettre en oeuvre en raison du peu d'espace disponible et à fortiori coûteuses.It is understood, of course, that these solutions are complex, difficult to implement because of the limited space available and all the more expensive.

L'invention a pour but de pallier les inconvénients de l'état de la technique en proposant à un dispositif d'entraînement pour système de fermeture de bâtiment de type volet roulant, porte de garage ou similaire, comportant un moteur coopérant avec des moyens d'entraînement aptes à actionner ledit système de fermeture, caractérisé par le fait que ledit moteur coopère avec lesdits moyens d'entraînement au travers de moyens de transmission mécaniques à débrayage automatique en cas d'arrêt de commande de fonctionnement dudit moteur pour autoriser un libre déplacement desdits moyens d'entraînement par rapport à ce dernier.The object of the invention is to overcome the drawbacks of the state of the art by proposing to a driving device for a rolling shutter, garage door or the like, comprising a motor cooperating with means drive adapted to actuate said closure system, characterized in that said motor cooperates with said drive means through mechanical transmission means with automatic disengagement in the event of an operating control stoppage of said motor to allow free movement said drive means with respect to the latter.

Tout particulièrement, lesdits moyens de transmission sont constitués d'une pièce d'entraînement mobile conçue de manière apte à occuper une première position débrayée dans laquelle elle coopère exclusivement avec une pièce motrice du moteur et une seconde position embrayée dans laquelle elle est repoussée sous l'action de ladite pièce motrice lors du fonctionnement dudit moteur pour coopérer en transmission avec une pièce réceptrice associée aux moyens d'entraînement et apte à actionner ledit système de fermeture.In particular, said transmission means consist of a movable drive part designed so as to occupy a first disengaged position in which it cooperates exclusively with a driving part of the engine and a second engaged position in which it is pushed back under the action of said driving part during operation of said motor to cooperate in transmission with a receiving part associated with the drive means and able to actuate said closure system.

Selon une autre particularité de l'invention, la pièce d'entraînement est conçue apte à être repoussée par la pièce motrice depuis la position débrayée en position embrayée contre l'action de moyens de rappel élastiques constituant des moyens de commande de débrayage en cas d'arrêt de fonctionnement du moteur.According to another particularity of the invention, the drive part is designed to be pushed back by the drive part from the disengaged position in the engaged position against the action of resilient return means constituting disengagement control means in case of disengagement. stopping the engine.

L'invention concerne encore un système de fermeture de bâtiment de type volet roulant, porte de garage ou similaire, comportant un tel dispositif d'entraînement selon l'invention, en combinaison avec des moyens de blocage dudit système de fermeture, notamment en position refermée, lesdits moyens de blocage étant conçus à commande automatique de déblocage en cas de fonctionnement du moteur dudit dispositif d'entraînement.The invention also relates to a building closure system of shutter type, garage door or the like, comprising such a drive device according to the invention, in combination with locking means of said closure system, in particular in the closed position , said locking means being designed to automatically release control in case operating the motor of said driving device.

Les avantages qui découlent de la présente invention apparaîtront au cours de la description détaillée qui va suivre se rapportant à un mode de réalisation donné à titre d'exemple indicatif et non limitatif.The advantages that flow from the present invention will become apparent from the following detailed description relating to an embodiment given by way of indicative and non-limiting example.

The understanding of this description will be facilitated by reference to the accompanying drawings in which:
  • the figure 1 shows schematically, in perspective and exploded view, an embodiment of a drive device according to the invention;
  • the figure 2 represents a schematic view in longitudinal section and in the disengaged position of this drive device according to the invention;
  • the figure 3 represents a schematic view in longitudinal section and in the engaged position of this drive device according to the invention;
  • the figure 4 represents a schematic view of the teeth according to a particular embodiment of the drive device according to the invention; and
  • the figure 5 is an illustration of an application of the drive device according to the invention to a shutter type closure system.

La présente invention qui est représentée dans les figures des dessins en annexe, concerne un dispositif d'entraînement 1 pour système de fermeture de bâtiment de type volet roulant, porte de garage ou similaire, sachant, en ce qui concerne lesdits portes de garage, que leur ouvrant peut être soit basculant soit du type sectionnel, soit à panneau repliable ou conçu apte à venir se ranger, de manière juxtaposée les uns derrière les autres, en position d'ouverture de ladite porte.The present invention, which is shown in the figures of the drawings in the appendix, relates to a driving device 1 for a rolling shutter type building system, a garage door or the like, knowing, with regard to said garage doors, that their opening can be either tilting or sectional type or foldable panel or designed able to come arrange, in a juxtaposed manner one behind the other, in the open position of said door.

Quoi qu'il en soit, ce dispositif d'entraînement 1 comporte un moteur 2 coopérant avec des moyens d'entraînement 3 conçus aptes à actionner ledit système de fermeture 4 lequel a été représenté, à titre d'exemple, sous forme d'un volet roulant 4 dans la figure 5 des dessins ci-joints.Anyway, this drive device 1 comprises a motor 2 cooperating with drive means 3 designed able to actuate said closure system 4 which has been shown, for example, in the form of a rolling shutter 4 in the figure 5 attached drawings.

Ainsi, dans ce mode de réalisation, le moteur 2 peut adopter la forme tubulaire prenant position dans un tube d'enroulement 5 et dont l'arbre d'entraînement 6 agit, au travers desdits moyens d'entraînement 3 sur le tube d'enroulement 5 en vue de commander l'enroulement ou le déroulement du tablier 7 dudit volet roulant 4.Thus, in this embodiment, the motor 2 can adopt the tubular form taking position in a winding tube 5 and whose driving shaft 6 acts through said drive means 3 on the winding tube 5 for controlling the winding or unfolding of the deck 7 of said shutter 4.

En fait, selon l'invention, ledit moteur 2 coopère avec les moyens d'entraînement 3 au travers de moyens de transmission mécaniques 8 à débrayage automatique en cas d'arrêt de commande de fonctionnement dudit moteur 2, ceci pour autoriser un libre déplacement desdits moyens d'entraînement 3 par rapport à ce dernier.In fact, according to the invention, said motor 2 cooperates with the drive means 3 through mechanical transmission means 8 with automatic disengagement in the event of an operating control stoppage of said motor 2, this to allow a free movement of said drive means 3 with respect to the latter.

En somme, dans l'exemple d'un volet roulant comme représenté dans la figure 5, lorsque l'alimentation du moteur 2 est coupée, les moyens d'entraînement 3 par l'intermédiaire desquels il agit sur le tube d'enroulement 5 sont désolidarisés de ce moteur 2. Ainsi, le tube d'enroulement 5 étant libre en rotation, l'ouverture et la fermeture du volet roulant 4 peut être commandée par action directe sur son tablier 7.In sum, in the example of a shutter as shown in the figure 5 when the power supply of the motor 2 is cut off, the drive means 3 by means of which it acts on the winding tube 5 are separated from this motor 2. Thus, the winding tube 5 being free to rotate , the opening and closing of the shutter 4 can be controlled by direct action on its apron 7.

On peut encore concevoir que cette ouverture et fermeture du volet roulant 4 intervienne au travers d'une commande manuelle, par exemple sous forme d'une poulie, manoeuvrable à l'aide d'une courroie ou d'un treuil commandé par une manivelle en liaison avec le tube d'enroulement 5.It can still be conceived that this opening and closing of the roller shutter 4 intervenes through a manual control, for example in the form of a pulley, operable by means of a belt or a winch controlled by a crank. connection with the winding tube 5.

De manière plus particulière, les moyens de transmission mécaniques 8 sont constitués d'une pièce d'entraînement mobile 9 conçue de manière apte à occuper, d'une part, une première position débrayée 10, plus particulièrement visible dans la figure 2 dans laquelle elle coopère exclusivement avec une pièce motrice 11 du moteur 2 et, d'autre part, une seconde position 12 embrayée, représentée dans la figure 3, dans laquelle elle est repoussée, sous l'action de la pièce motrice 11, lors du fonctionnement dudit moteur 2, pour coopérer en transmission avec une pièce réceptrice 13 associée aux moyen d'entraînement 3 et apte à actionner ledit système de fermeture 4.More particularly, the mechanical transmission means 8 consist of a movable driving part 9 designed in such a way as to occupy, on the one hand, a first disengaged position 10, more particularly visible in the figure 2 in which it cooperates exclusively with a driving part 11 of the engine 2 and, secondly, a second position 12 engaged, shown in FIG. figure 3 , in which it is pushed back, under the action of the driving part 11, during operation of said motor 2, to cooperate in transmission with a receiving member 13 associated with the drive means 3 and able to actuate said closure system 4.

Selon l'invention, la pièce d'entraînement 9 est conçue apte à être repoussée par la pièce motrice 11 depuis la position débrayée 10 en position embrayée 12 contre l'action de moyens de rappel élastiques 14 constituant, substantiellement, des moyens de commande de débrayage en cas d'arrêt de fonctionnement du moteur 2.According to the invention, the driving part 9 is designed to be pushed back by the driving part 11 from the disengaged position 10 in the engaged position 12 against the action of elastic return means 14 constituting, substantially, control means of disengagement in case of engine stoppage 2.

Selon un mode de réalisation avantageux, la pièce d'entraînement mobile 9 se présente sous forme d'une bague 15 montée libre en déplacement axial sur un arbre support 16 et comportant sur chacun de ses chants annulaires 17, 18 une denture 19, 20. Celle-ci est conçue apte à s'engrener avec des dentures complémentaires 21, 22, respectivement, de la pièce motrice 11 et la pièce réceptrice 13 sous forme de roues d'engrenage sachant que la première est conçue apte à être commandée en rotation par le moteur tandis que la seconde est solidarisée pour la commande du système de fermeture 4.According to an advantageous embodiment, the movable drive part 9 is in the form of a ring mounted freely in axial displacement on a support shaft 16 and having on each of its annular edges 17, 18 a toothing 19, 20. It is designed to mesh with complementary teeth 21, 22, respectively, of the driving part 11 and the receiving part 13 in the form of gear wheels, knowing that the first is designed to be rotatably controlled by the engine while the second is secured for the control of the closure system 4.

Selon un mode d'exécution préférentiel, la roue dentée correspondant à la pièce motrice 11 et portant la denture 21 est montée coaxiale à l'arbre support 16 sur lequel est par ailleurs montée, immobilisée en translation, la roue portant la denture 22 de la pièce réceptrice 13.According to a preferred embodiment, the toothed wheel corresponding to the driving part 11 and bearing the toothing 21 is mounted coaxially with the support shaft 16 on which is also mounted, immobilized in translation, the wheel bearing the toothing 22 of the receiving room 13.

A titre indicatif, celle-ci a été représentée dans les dessins joints en annexe de forme polygonale ajustée à la section interne polygonale du tube d'enroulement 5 d'un tablier 7 de volet roulant.As an indication, this has been shown in the accompanying drawings of polygonal shape fitted to the polygonal inner section of the winding tube 5 of an apron 7 shutter.

Chaque denture 21, 22 respectivement de la pièce motrice 11 et de la pièce réceptrice 13, auxquelles correspondent les dentures 19, 20 de la pièce d'entraînement mobile 9, comporte au moins une dent et de préférence plusieurs.Each toothing 21, 22 respectively of the driving part 11 and the receiving part 13, which correspond to the teeth 19, 20 of the movable driving part 9, comprises at least one tooth and preferably several.

Ces dentures 21, 22 des pièces motrices 11 et réceptrices 13 ont une hauteur de dents 23, 24 différente, la hauteur 23 de dents de la pièce motrice 11 étant supérieure à celle 24 de la pièce réceptrice 13. En particulier, la hauteur de dents 23 de la denture 21 correspondant à la pièce motrice 11 est supérieure à la course de déplacement axial 25 de la pièce d'entraînement 9 laquelle course 25 est au moins égale à la hauteur de dents 24 de la denture 22 correspondant à la pièce réceptrice 13, précisément pour permettre à la pièce d'entraînement 9 de passer depuis une position débrayée 10 dans une position embrayée 12 et vice-versa par rapport à ladite pièce réceptrice 13.These toothings 21, 22 of the driving and receiving parts 11 have a height of teeth 23, 24 different, the height 23 of teeth of the driving part 11 being greater than that 24 of the receiving part 13. In particular, the height of teeth 23 of the toothing 21 corresponding to the driving part 11 is greater than the axial displacement travel 25 of the drive part 9 which stroke 25 is at least equal to the height of the teeth 24 of the toothing 22 corresponding to the receiving part 13 , precisely to allow the driving part 9 to pass from a disengaged position 10 into an engaged position 12 and vice versa with respect to said receiving part 13.

De manière particulière, encore, les dents 21A de la pièce motrice 11 comportent des flancs 26 inclinés selon un angle α par rapport à l'axe longitudinal de déplacement de la pièce d'entraînement en rappelant que les dents de la denture 19 correspondante de cette pièce d'entraînement 9 comporte une forme conjuguée.In a particular way, again, the teeth 21A of the driving part 11 comprise flanks 26 inclined at an angle α with respect to the longitudinal axis of displacement of the driving part by reminding that the teeth of the corresponding toothing 19 of this driving piece 9 has a conjugate shape.

Ainsi, sous l'action combinée de ces dents au plan incliné des dentures respectivement 21, 22 de la pièce motrice 11 et de la pièce d'entraînement 9 ainsi que de moyens de freinage en rotation 27 de cette dernière, la commande en rotation par le moteur 2 de ladite pièce motrice 11 a pour conséquence de soumettre cette pièce d'entraînement mobile 9 à un couple de rotation mais aussi à une force résultante axiale ayant tendance à repousser celle-ci en direction de la pièce réceptrice 13 provoquant l'engrènement des dentures 20 et 22 donc de la rotation des moyens d'entraînement 3.Thus, under the combined action of these teeth to the inclined plane of the teeth respectively 21, 22 of the drive part 11 and the drive part 9 and means of braking in rotation 27 of the latter, the control in rotation by the motor 2 of said driving part 11 has the effect of subjecting this mobile drive part 9 to a pair of rotation but also to a resultant axial force tending to push it towards the receiving member 13 causing the meshing of the teeth 20 and 22 thus the rotation of the drive means 3.

A noter que le déplacement de la pièce d'entraînement mobile 9 se fait contre l'action des moyens de rappel élastiques 14 sous forme d'un ressort de compression hélicoïdal 28 s'interposant entre cette pièce d'entraînement 9 et la pièce réceptrice 13 sur l'arbre support 16.Note that the displacement of the movable drive part 9 is against the action of the elastic return means 14 in the form of a helical compression spring 28 interposed between the drive part 9 and the receiving part 13 on the support shaft 16.

Il est à noter, à ce propos, que la raideur de ce ressort de compression 24 est choisie pour que, sous l'influence de l'inclinaison des flancs 26 des dents 21A, du couple de transmission du moteur 2 et du couple résistant produit par les moyens de freinage 27, il en résulte bien le déplacement de la pièce d'entraînement mobile 9 depuis sa position débrayée 10 dans sa position embrayée 12.It should be noted, in this connection, that the stiffness of this compression spring 24 is chosen so that, under the influence of the inclination of the flanks 26 of the teeth 21A, the transmission torque of the motor 2 and the resistant torque produced by the braking means 27, this results in the displacement of the movable drive part 9 from its disengaged position 10 in its engaged position 12.

En ce qui concerne les dents correspondant aux dentures 20 et 22 respectivement de la pièce d'entraînement 9 et de la pièce réceptrice 13, elles peuvent être à flanc droit ou incliné sachant que leur angle d'inclinaison étant choisi dans tous les cas inférieur à l'angle α d'inclinaison des flancs 26 des dents 21A.With regard to the teeth corresponding to the teeth 20 and 22 respectively of the driving part 9 and the receiving part 13, they can be on the right or inclined side, knowing that their angle of inclination is chosen in all cases less than the angle α of inclination of the flanks 26 of the teeth 21A.

A noter en ce qui concerne les moyens de freinage 27 que ceux-ci peuvent adopter différents modes de réalisation, en particulier sous forme de moyens de frottement. Dans les dessins joints, ces moyens de freinage 27 adoptent la forme d'une bille 29 à ressort 28 logée dans l'épaisseur de la bague 15 constituant la pièce d'entraînement mobile 9 et coopérant avec un tube extérieur 30 fixe correspondant, par exemple, au tube carter d'un moteur 2 de forme tubulaire.Note with regard to the braking means 27 that they can adopt different embodiments, in particular in the form of friction means. In the accompanying drawings, these braking means 27 take the form of a spring-loaded ball 29 28 housed in the thickness of the ring 15 constituting the movable drive part 9 and co-operating with a corresponding fixed outer tube 30, for example , to the casing tube of a motor 2 of tubular form.

L'invention concerne encore un système de fermeture 4 de bâtiment de type volet roulant pour porte de garage ou similaire comportant un tel dispositif d'entraînement 1, ceci en combinaison avec des moyens de verrouillage 31 dudit système 1 notamment en position de fermeture.The invention further relates to a closure system 4 of rolling shutter type building for garage door or the like comprising such a drive device 1, this in combination with locking means 31 of said system 1 in particular in the closed position.

Tout particulièrement, de tels moyens de verrouillage 31 sont conçus aptes à être déverrouillés automatiquement lors de la commande de fonctionnement du moteur 2 et, contrairement, à adopter une position de verrouillage lorsque ce moteur 2 est arrêté.In particular, such locking means 31 are designed to be unlocked automatically during the operation control of the engine 2 and, in contrast, to adopt a locking position when the engine 2 is stopped.
