Description

La présente invention a trait aux stores, volets roulants et autres ensembles dans lesquels l'organe souple de fermeture est enroulé sur un tambour qui est entraîné en rotation par un moteur électrique et auquel est associé un dispositif apte à assurer son freinage automatique afin d'immobiliser l'organe précité dès que ledit moteur électrique n'est plus alimenté.The present invention relates to blinds, roller shutters and other assemblies in which the flexible closing member is wound on a drum which is rotated by an electric motor and with which is associated a device capable of ensuring its automatic braking in order to immobilize the aforementioned member as soon as said electric motor is no longer supplied with power.

L'état de la technique est particulièrement bien illustré par le document FR-A-1 103 282 (SOC. FATA) qui décrit un dispositif de commande motorisée pour stores et similaires, entièrement logé à l'intérieur d'un boîtier ou bâti fixe engagé axialement dans le tambour enrouleur. Ce dispositif comprend, outre le moteur électrique d'entraînement, d'une part un frein apte à immobiliser angulairement le tambour dès que ledit moteur n'est plus excité, d'autre part un mécanisme de commande manuelle propre à assurer, en cas de panne du moteur, le déblocage du frein en vue de l'actionnement manuel du tambour.The state of the art is particularly well illustrated by the document FR-A-1 103 282 (SOC. FATA) which describes a motorized control device for blinds and the like, entirely housed inside a fixed housing or frame. axially engaged in the take-up drum. This device comprises, in addition to the electric drive motor, on the one hand a brake capable of angularly immobilizing the drum as soon as said motor is no longer excited, on the other hand a manual control mechanism capable of ensuring, in the event of engine failure, brake release for manual actuation of the drum.

A cet effet le moteur est à induit conique afin d'opérer, au début de son fonctionnement, un déplacement de l'arbre provoquant l'ouverture du frein, le blocage intervenant dès que l'alimentation cesse sous l'effet d'un ressort agissant sur l'arbre du moteur. Le frein est constitué par deux disques dont l'un est porté par le boîtier fixe tandis que l'autre est calé sur l'arbre du moteur. Le mécanisme de commande manuelle associé à ce frein comprend une came frontale qui est susceptible d'être déplacée angulairement par traction sur un câble de manoeuvre, ce déplacement angulaire déterminant une poussée axiale qui met hors fonctionnement le frein et permet simultanément l'accouplement de l'arbre du moteur avec un système d'actionnement manuel de secours.To this end, the motor has a conical armature in order to operate, at the start of its operation, a displacement of the shaft causing the brake to open, blocking occurring as soon as the supply ceases under the effect of a spring. acting on the motor shaft. The brake consists of two discs, one of which is carried by the fixed housing while the other is wedged on the motor shaft. The manual control mechanism associated with this brake comprises a front cam which is capable of being angularly displaced by traction on an operating cable, this angular displacement determining an axial thrust which puts the brake out of operation and simultaneously allows the coupling of the motor shaft with manual emergency actuation system.

L'un des buts de l'invention est la réalisation d'un dispositif de freinage automatique du type susvisé qui, en dépit d'une construction mécanique simplifiée par rapport à la technique usuelle, se révèle d'une efficacité remarquable en ce qui concerne l'effort de freinage.One of the aims of the invention is the production of an automatic braking device of the aforementioned type which, despite a simplified mechanical construction compared to the usual technique, is remarkably effective with regard to braking force.

Un autre but de l'invention est de doter le dispositif d'un système de déblocage qui soit susceptible d'être aisément manoeuvré à la main en cas de panne du courant d'alimentation.Another object of the invention is to provide the device with an unlocking system which is capable of being easily operated by hand in the event of a failure of the supply current.

Le dispositif suivant l'invention est défini à la revendication 1.The device according to the invention is defined in claim 1.

Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer:The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing:

La figure unique de ce dessin est une coupe illustrant l'agencement d'un dispositif de freinage automatique établi conformément à l'invention.The single figure of this drawing is a section illustrating the arrangement of an automatic braking device established in accordance with the invention.

Sur ce dessin, on a supposé que la toile ou autre organe mobile de fermeture du store ou volet roulant envisagé s'envidait sur un tambour 1 à l'intérieur duquel est directement monté le bâti tubulaire fixe 2 qui renferme le moteur électrique destiné à l'entraînement du tambour 1 précité. Ce moteur électrique, susceptible de tourner dans les deux sens, comprend un stator 3 qui est alimenté par des conducteurs schématisés en 4 et dont l'empilage de tôles entoure un rotor 5. Ce dernier est calé sur un arbre 6 orienté axialement par rapport au bâti fixe 2, les deux extrémités de cet arbre 6 dépassant de part et d'autre du moteur 3-5, d'un côté pour assurer l'entraînement d'un mécanisme réducteur lié au tambour 1, de l'autre pour coopérer avec le dispositif de freinage automatique objet de l'invention.In this drawing, it has been assumed that the fabric or other movable member for closing the blind or envisaged rolling shutter is emptied onto a drum 1 inside which is directly mounted the fixed tubular frame 2 which encloses the electric motor intended for the drive of the aforementioned drum 1. This electric motor, capable of turning in both sense, includes a stator 3 which is supplied by conductors shown diagrammatically at 4 and whose stacking of sheets surrounds a rotor 5. The latter is wedged on a shaft 6 oriented axially with respect to the fixed frame 2, the two ends of this shaft 6 protruding on either side of the motor 3-5, on one side to ensure the drive of a reduction mechanism linked to the drum 1, on the other to cooperate with the automatic braking device object of the invention .

Sur l'extrémité considérée de l'arbre 6 est montée librement une culasse 7 en métal magnétique, dont l'extrémité tournée en direction du rotor 5 est creusée d'une dépression ou cuvette cylindrique 7a à l'intérieur de laquelle vient s'engager une saillie annulaire 5a prévue sur ledit rotor. Dans l'espace axial libre ainsi ménagé entre la culasse 7 et le rotor 5 est logé un ressort 8 qui entoure l'arbre 6 et qui tend à écarter élastiquement ladite culasse du rotor.On the considered end of the shaft 6 is freely mounted a yoke 7 made of magnetic metal, the end of which faces towards the rotor 5 is hollowed out by a cylindrical depression or bowl 7 a inside which comes engaging an annular projection 5 is provided on said rotor. In the free axial space thus formed between the cylinder head 7 and the rotor 5 is housed a spring 8 which surrounds the shaft 6 and which tends to elastically separate said cylinder head from the rotor.

A l'opposé de la cuvette 7a, cette culasse 7 comporte un plateau 7b que le ressort 8 tend à appliquer contre un disque 9 en une matière à fort coefficient de friction, lequel disque est immobilisé angulairement par au moins une clavette longitudinale 10a solidaire d'une entretoise fixe 10 rapportée à l'intérieur du bâti 2. Le disque 9 est en fait pincé entre le plateau 7b précité et un plateau opposé 11 convenablement immobilisé sur l'arbre 6, par exemple à l'aide d'une goupille 12. On observera que le plateau 11 est librement traversé par des doigts longitudinaux 13 fixés à l'intérieur de logements borgnes ménagés dans la culasse 7.Opposite the bowl 7 a , this cylinder head 7 comprises a plate 7 b which the spring 8 tends to apply against a disc 9 made of a material with a high coefficient of friction, which disc is angularly immobilized by at least one longitudinal key 10 a secured to a fixed spacer 10 attached to the inside of the frame 2. The disc 9 is in fact pinched between the aforementioned plate 7b and an opposite plate 11 suitably immobilized on the shaft 6, for example using 'a pin 12. It will be observed that the plate 11 is freely traversed by longitudinal fingers 13 fixed inside blind housings formed in the cylinder head 7.

L'entretoise 10, qui renferme l'un des paliers 14 de l'arbre 6, est solidaire d'un étrier 15 qui est tourné à l'opposé du disque 9 et qui supporte une chape 16 sur l'axe 16a de laquelle pivote un petit levier 17 susceptible d'être manoeuvré manuellement à distance à l'aide d'un câble 18. l'extrémité de ce levier 17 qui est tournée vers l'intérieur du bâti 2 est appliquée contre la partie centrale d'une barrette 19 pourvue de poussoirs 20 montés à coulissement dans des perforations de l'entretoise 10; des ressorts 21, portés par les poussoirs 20 et prenant appui contre l'entretoise 10, tendent à repousser la barrette 19 contre le levier basculant 17.The spacer 10, which contains one of the bearings 14 of the shaft 6, is integral with a stirrup 15 which is turned opposite to the disc 9 and which supports a yoke 16 on the axis 16 a of which pivots a small lever 17 capable of being manually operated remotely using a cable 18. the end of this lever 17 which is turned towards the inside of the frame 2 is applied against the central part of a bar 19 provided with pushers 20 slidably mounted in the perforations of the spacer 10; springs 21, carried by the pushers 20 and bearing against the spacer 10, tend to push the bar 19 against the rocking lever 17.

Les poussoirs 20 traversent l'entretoise 10 afin de venir porter contre la bague extérieure d'un roulement à billes 22, du type à gorges profondes, dont la bague intérieure coulisse et tourne sur le moyeu du plateau 11 lié à l'arbre 6. On conçoit dans ces conditions que la manoeuvre du levier basculant 17 à l'aide du câble 18 (dont l'extrémité libre est accessible en dehors du bâti 2) provoque, par appui des poussoirs 20 contre le roulement 22, le déplacement axial de celui-ci qui a son tour repousse les doigts 13 et la culasse 7 à l'encontre du ressort 8.The pushers 20 pass through the spacer 10 in order to bear against the outer ring of a ball bearing 22, of the deep groove type, the inner ring of which slides and rotates on the hub of the plate 11 linked to the shaft 6. It is therefore conceivable that the operation of the rocking lever 17 to using the cable 18 (whose free end is accessible outside the frame 2) causes, by pressing the pushers 20 against the bearing 22, the axial displacement of the latter which in turn repels the fingers 13 and the cylinder head 7 against spring 8.

Le fonctionnement et le mode d'utilisation du dispositif de freinage automatique suivant l'invention découlent des explications qui précèdent et se comprennent aisément.The operation and the mode of use of the automatic braking device according to the invention follow from the foregoing explanations and are easily understood.

Lorsque le moteur électrique 3-5 n'est pas excité, le ressort 8 repousse axialement la culasse 7 en direction du disque 9 qui de ce fait se trouve pincé entre les deux plateaux 7b et 11; on notera que l'effet de freinage obtenu est très puissant puisqu'il s'exerce simultanément sur les deux faces opposées du disque 9.When the electric motor 3-5 is not energized, the spring 8 pushes the cylinder head 7 axially in the direction of the disc 9 which is therefore pinched between the two plates 7 b and 11; it will be noted that the braking effect obtained is very powerful since it is exerted simultaneously on the two opposite faces of the disc 9.

Dès que le moteur 3-5 est excité, la culasse 7 est attirée axialement par le flux magnétique, à l'encontre du ressort 8 qui est comprimé. Les plateaux 7b et 11 ne sont donc plus appliqués contre le disque 9, si bien que l'arbre 6 est libre de tourner pour l'entraînement du tambour 1 dans un sens ou dans l'autre. Sous l'effet du ressort 8, cette liberté de rotation cesse dès que le moteur n'est plus alimenté, ce qui a pour résultat d'immobiliser automatiquement le tambour 1 et l'organe de fermeture (toile ou autre) qui lui est associé.As soon as the motor 3-5 is energized, the cylinder head 7 is attracted axially by the magnetic flux, against the spring 8 which is compressed. The plates 7b and 11 are therefore no longer applied against the disc 9, so that the shaft 6 is free to rotate for driving the drum 1 in one direction or the other. Under the effect of the spring 8, this freedom of rotation ceases as soon as the motor is no longer supplied, which has the result of automatically immobilizing the drum 1 and the closing member (canvas or other) associated with it .

Si l'utilisateur entend manoeuvrer manuellement le store ou volet roulant alors que par suite d'une panne d'alimentation le moteur 3-5 ne peut être excité, il lui suffit d'exercer une traction sur le câble 18 pour déplacer axialement la culasse 7 à l'encontre du ressort 8 et libérer ainsi le tambour 1.If the user intends to operate the blind or rolling shutter manually while the motor 3-5 cannot be energized as a result of a power failure, it suffices to pull the cable 18 to move the cylinder head axially 7 against the spring 8 and thus release the drum 1.

Il va de soi que le nombre des doigts 13, des poussoirs 20 et des clavettes 10a peut varier dans une large mesure.It goes without saying that the number of fingers 13, pushers 20 and keys 10 a can vary to a large extent.
