Description
La présente invention a trait aux dispositifs de fermeture à commande électrique du type des volets roulants et similaires.The present invention relates to electrically controlled closing devices of the type of roller shutters and the like.
On sait que lorsqu'en dépit de sa déformabilité qui lui permet de s'enrouler sur le tambour tournant de manoeuvre, le tablier mobile de fermeture des dispositifs du type envisagé présente une rigidité totale dans le sens vertical, le risque surgit que la descente dudit tablier provoque le coincement du corps d'un enfant entre le bord libre de ce tablier et le sol. Aussi a-t-on proposé d'insérer, entre l'arbre de sortie du moto-réducteur électrique d'entraînement et le tambour de manoeuvre, un système de roue libre agencé de façon à faire automatiquement cesser le mouvement de descente du tablier dès que le bord libre de ce dernier rencontre une résistance mécanique.It is known that when, despite its deformability which allows it to be wound on the rotating maneuvering drum, the movable apron for closing devices of the envisaged type has total rigidity in the vertical direction, the risk arises that the descent of said apron causes a child's body to be trapped between the free edge of this apron and the floor. It has therefore been proposed to insert, between the output shaft of the electric drive geared motor and the drive drum, a free wheel system arranged so as to automatically stop the downward movement of the deck from that the free edge of the latter meets mechanical resistance.
Il convient toutefois d'observer qu'un tel système de roue libre se révèle insufisant pour assurer une sécurité totale vis-à-vis des enfants ou autres obstacles. Pour améliorer la sécurité, le document US-A-3 471 969 (UTTMANN) prévoit d'associer aux deux organes concentriques de la roue libre intermédiaire, des moyens agencés de façon à ce que le mouvement relatif qui apparaît entre lesdits organes lorsque le bord libre du tablier ou analogue, par portée contre un obstacle au cours de son mouvement de descente, immobilise angulairement le tambour, provoque, par actionnement d'un contacteur branché sur le circuit électrique d'alimentation du moto-réducteur, l'inversion automatique du sens de rotation du tambour et la remontée immédiate du tablier.However, it should be noted that such a freewheel system proves to be insufficient to ensure total safety vis-à-vis children or other obstacles. To improve safety, document US-A-3,471,969 (UTTMANN) provides for combining with the two concentric members of the intermediate freewheel, means arranged so that the relative movement which appears between said members when the edge free of the apron or the like, by bearing against an obstacle during its downward movement, angularly immobilizes the drum, causes, by actuation of a contactor connected to the electrical supply circuit of the gear motor, the automatic reversal of the direction of rotation of the drum and immediate raising of the apron.
On conçoit qu'un tel agencement permet l'obtention d'une sécurité totale, puisque l'arrêt automatique du mouvement de descente du tablier réalisé par le système de roue libre est immédiatement suivi de la remontée dudit tablier qui libère ainsi la partie du corps qui était coincée par celui-ci.It is understood that such an arrangement allows total security to be obtained, since the automatic stopping of the downward movement of the deck produced by the freewheel system is immediately followed by the ascent of said deck which thus frees the part of the body who was trapped by it.
Cependant le mécanisme décrit et représenté dans le document précité fait appel à un nombre élevé de pièces délicates et coûteuses et sa complexité est telle que sa fiabilité est réduite et nuit finalement à la sécurité de l'ensemble.However, the mechanism described and shown in the aforementioned document uses a large number of delicate and expensive parts and its complexity is such that its reliability is reduced and ultimately affects the security of the assembly.
C'est à cet inconvénient qu'entend remédier la présente invention, laquelle a pour objet le mécanisme de sécurité qui est défini à la revendication 1.It is to this drawback that the present invention intends to remedy, which relates to the safety mechanism which is defined in the
Suivant l'invention les moyens associés aux deux organes de la roue libre comprennent d'une part une pièce cylindrique en forme de support solidaire du tambour et pourvu d'une denture latérale, d'autre part un disque rendu angulairement solidaire de l'organe de la roue libre qui est lié en permanence à l'arbre de sortie du moto-réducteur. Ce disque comporte lui-même une denture conjuguée à la denture précitée, les deux dentures étant maintenues appliquées l'une contre l'autre par des moyens élastiques de façon à ce que ledit disque se déplace axialement à l'encontre des moyens élastiques pour actionner le contacteur électrique quand sa denture est repoussée axialement par la denture opposée sous l'effet de l'immobilisation angulaire du tambour qui intervient lorsque le tablier heurte un obstacle.According to the invention, the means associated with the two freewheel members comprise on the one hand a cylindrical part in the form of a support integral with the drum and provided with lateral toothing, on the other hand a disc made angularly integral with the member of the freewheel which is permanently linked to the output shaft of the gear motor. This disc itself has a toothing conjugated to the aforementioned toothing, the two toothing being kept applied against one another by elastic means so that said disc moves axially against the elastic means for actuating the electrical contactor when its toothing is pushed axially by the opposite toothing under the effect of the angular immobilization of the drum which occurs when the apron strikes an obstacle.

Fig. 5 est un schéma très simplifié de l'intallation électrque du dispositif suivant fig. 1.Fig. 5 is a very simplified diagram of the electrical installation of the device according to FIG. 1.
A la façon en soi connue, le dispositif de volet roulant représenté en fig. 1 comprend un tablier mobile 1 dont le bord supérieur est rendu solidaire d'un tambour tournant de manoeuvre 2, lequel est supporté à rotation, au niveau de ses extrémités, par deux équerres 3 fixées dans l'embrasure 4 fermée par le dispositif considéré. A l'intérieur de ce tambour 2 est logé un moto-réducteur 5 à commande électrique, dont la carcasse ou stator est porté par l'une des équerres 3, tandis que son arbre de sortie à vitesse lente est lié angulairement audit tambour 2 par une roue libre 6.In the known manner, the roller shutter device shown in FIG. 1 comprises a
Comme montré en fig. 2, cette roue libre 6 comprend deux organes concentriques 7 et 8. L'organe extérieur 7, établi à un profil octogonal dans l'exemple de réalisation envisagé, est fixé au tambour 2 à l'aide d'une vis radiale 9, tandis que l'organe intérieur 8, en forme de bague, est percé d'une ouverture axiale établie à un profil carré pour recevoir l'arbre de sortie 10 du moto-réducteur 5. Dans la périphérie de cette bague ou organe 8 sont ménagées quatre cavités dont chacune renferme un doigt oblique 11 associé à un ressort 12 qui, lorsque l'arbre 10 entraîne l'organe 8 dans le sens indiqué par la flèche F, tend à engager ledit doigt dans l'une d'une série d'empreintes 7a pratiquées dans l'ouverture de l'organe extérieur 7.As shown in fig. 2, this
Un tel système de roue libre, dont la construction est bien connue en pratique, fonctionne à la manière habituelle telle qu'exposée plus haut.Such a freewheel system, the construction of which is well known in practice, operates in the usual manner as set out above.
Lorsque le moto-réducteur 5 est alimenté électriquement de manière à entraîner l'arbre 10 dans le sens correspondant à la flèche F, cet arbre est rigidement lié au tambour 2 qui opère alors la montée du tablier 1. Par contre, quand moyennant inversion de l'alimentation électrique du moto-réducteur 5, l'arbre 10 tourne en sens inverse, les doigts 11 n'exercent qu'une simple friction sur l'organe extérieur 7, si bien que celui-ci s'immobilise dès qu'au cours du mouvement de descente le bord inférieur libre du tablier 1 rencontre une résistance supérieure à la normale, les doigts précités s'éclipsant dans leur logement à l'encontre des ressorts 12 en permettant à l'organe 8 de continuer sa rotation alors que l'organe 7 est immobilisé.When the
Conformément à l'invention et comme représenté en fig. 1, il est prévu un manchon d'entraînement 13 qui est rendu solidaire, à l'aide de vis telles que 14, de l'organe intérieur ou bague 8 de la roue libre 6. Dans l'extrémité libre de ce manchon 13 est emboîtée une entretoise 15 à section carrée qui s'étend axialement dans le tambour 2 au-delà de ladite roue libre 6. Dans l'extrémité opposée de cette entretoise 15 est introduit l'embout terminal 16a (fig. 3 et 4) d'un arbre 16 qui traverse axialement un support cylindrique 17 monté à l'intérieur de l'extrémité correspondante du tambour 2 dont il est rendu solidaire à l'aide de vis radiales 18.According to the invention and as shown in fig. 1, a
On notera que le support 17 est solidaire d'un prolongement axial cylindrique 17a qui est engagé dans un coussinet 19 porté par l'équerre 3, comme montré en fig. 4. La retenue axiale de l'arbre 16 est opérée à l'aide d'une bride annulaire 16b apte à venir porter contre la face intérieure du support 17. La face transversale libre de ce support 17 qui est située au-delà du coussinet 18 est usinée pour présenter une denture 17b qui est destinée à coopérer avec une denture conjuguée 20a ménagée sur un bossage tubulaire 20b formant moyeu pour un disque 20. Ce dernier est porté par l'arbre 16 auquel il est lié angulairement par une goupille tranversale 21 introduite dans une lumière axiale 20c pratiquée dans un prolongement 20d du disque 20. Un ressort 22, engagé autour du prolongement 20d et prenant appui contre un écrou 23 vissé sur l'extrémité filetée de l'arbre 16 qui dépasse au-delà du prolongement 20c, assure l'application élastique de la denture 20a contre la denture 17b moyennant coulissement axial du disque 20.It will be noted that the
Ce dernier est destiné à opérer, ainsi qu'on le verra plus loin, l'actionnement de l'organe mobile de commande 24a d'un contacteur électrique 24 fixé contre une petite console 25 rapportée contre l'équerre 3 qui supporte le coussinet 19. l'insertion de ce contacteur 24 dans le circuit électrique d'alimentation du moto-réducteur 5 ressort de l'examen du schéma, très simplifié, de fig. 5.The latter is intended to operate, as will be seen below, the actuation of the movable control member 24 a of an
La commande de ce moto-réducteur 5 dans les deux sens de rotation correspondant à la montée et à la descente du tablier 1 est assurée par un commutateur 26 que, pour la commodité des explications, on a supposé être actionné à l'aide de deux bobinages opposés 26a et 26b, le premier intervenant pour la montée dudit tablier, le second pour la descente. La manoeuvre du commutateur 26 par l'utilisateur est opérée à l'aide d'un sélecteur 27 qui peut être soit du type manuel, soit du type à télécommande. A ce sélecteur 27 est attelé l'organe mobile d'un relais 28 qui, lorsqu'il est excité alors que le tablier 1 descend, ramène ledit sélecteur 27 à la position pour laquelle le bobinage 26a est alimenté.The control of this geared
C'est sur l'alimentation de ce relais 28 qu'est branché le contacteur 24 sus-mentionné.The above-mentioned
Le fonctionnement du mécanisme de sécurité suivant l'invention découle des explications qui précèdent et se comprend aisément. Lorsqu'aucun obstacle ne vient perturber le déplacement du tablier 1, le dispositif de volet roulant se comporte de façon absolument normale, la commande du sélecteur 27 assurant la manoeuvre dudit tablier à la montée et à la descente. Si par contre le bord libre de ce tablier 1 heurte un obstacle au cours de sa descente, le coincement de cet obstable entre ledit bord libre et le sol provoque l'entrée en action de la roue libre 6, en ce sens que l'organe extérieur 7 de cette roue libre s'immobilise angulairement moyennant escamotage des doigts 11, alors que l'organe intérieur ou bague 8 continue sa rotation. Le blocage du tambour 2 et du support 17 alors que l'arbre 16 et son disque coulissant 20 continuent à tourner détermine, par suite de l'intervention des deux dentures 17b et 20a agissant à la manière de rampes, le recul axial du disque 20 et l'actionnement du contacteur 24.The operation of the safety mechanism according to the invention follows from the foregoing explanations and is easily understood. When no obstacle disturbs the movement of the
Dans ces conditions, le relais 28 est alimenté et assure en conséquence le rappel du sélecteur 27 à la position correspondant à l'alimentation du bobinage 26a, si bien qu'immédiatement après s'être immobilisé au cours de son mouvement de descente, le tablier 1 s'élève en libérant l'obstacle. La sécurité ainsi obtenue est totale.Under these conditions, the
Il va de soi qu'en pratique, le schéma de l'installation électrique du volet roulant est plus complexe, celui suivant fig. 5 n'ayant été indiqué que pour permettre la compréhension du fonctionnement du mécanisme de sécurité.It goes without saying that in practice, the diagram of the electrical installation of the roller shutter is more complex, that according to FIG. 5 having been indicated only to allow the understanding of the operation of the security mechanism.
