Description

La présente invention concerne un dispositif d'entraínement pour la rotation sélective de lames d'un volet roulant ou d'un store ou d'une affiche publicitaire tournante.The present invention relates to a drive device for rotation selection of slats from a rolling shutter or blind or advertising poster rotating.

L'invention s'applique en particulier mais non limitativement à l'entraínement en rotation des lames d'un dispositif d'ouverture-fermeture à lames pivotantes pouvant être recouvertes d'un miroir, tel que décrit dans la demande PCT / FR 97/38202.The invention applies in particular but not limited to training in rotation of the blades of an opening-closing device with pivoting blades can be covered with a mirror, as described in the PCT / FR application 97/38202.

Une demande de brevet français déposée sous le n° FR 99 16810 propose déjà un dispositif remplissant cette fonction, comportant principalement un ensemble de chariots, chacun adjacent à une extrémité d'une lame et solidarisé à ladite lame par un axe fileté, les chariots étant par ailleurs solidarisé à une barre de commande verticale déplacée en direction horizontale par un système à crémaillère et engrenages.A French patent application filed under the number FR 99 16810 proposes already a device fulfilling this function, mainly comprising a set of carriages, each adjacent to one end of a blade and secured to said blade by a threaded axis, the carriages also being secured to a bar of vertical control moved in horizontal direction by a rack system and gears.

En outre, les moyens pour solidariser les chariots à la barre de commande sont constitués de doigts escamotables, et maintenus saillants en position de solidarisation grâce à des ressorts.In addition, the means for securing the carriages to the control bar consist of retractable fingers, and kept projecting in position joining thanks to springs.

Le dispositif décrit dans cette demande de brevet comporte de nombreux inconvénients tant au niveau du fonctionnement qu'au niveau du montage et du coût, énumérés non limitativement ci-après :

  • nombre de pièces important.
  • tolérances trop importantes et ne pouvant être réduites.
  • coincements fréquents empêchant l'ouverture du volet et pouvant entraíner des casses.
  • frottements trop importants au niveau des crémaillères, poulies, pignons, barre, chariots dont le poids est en outre supporté par l'axe du moteur situé en partie basse d'où nécessité d'un moteur de puissance importante, d'où un rendement mécanique très faible.
  • largeur non diminuable des montants latéraux contenant l'ensemble mécanique crémaillère, poulie, pignons, barre, chariot ; d'où réduction de l'espace d'ouverture.
The device described in this patent application has many drawbacks both in terms of operation and in terms of assembly and cost, which are not limited to below:
  • large number of pieces.
  • tolerances too large and cannot be reduced.
  • Frequent jamming preventing the opening of the shutter and possibly causing breakage.
  • Too much friction at the level of the racks, pulleys, pinions, bar, carriages the weight of which is also supported by the axis of the motor located in the lower part, hence the need for a large power motor, hence a mechanical efficiency very weak.
  • non-decreasing width of the lateral uprights containing the mechanical rack, pulley, pinion, bar, carriage assembly; hence reduction of the opening space.

Le demandeur a donc cherché à mettre au point un dispositif d'entraínement d'un concept mécanique totalement différent pour paliers à tous les inconvénients ci-dessus.The applicant therefore sought to develop a training device a completely different mechanical concept for bearings with all the disadvantages above.

Ce but est atteint par l'invention qui consiste en un dispositif d'entraínement pour la rotation sélective des lames d'un tablier par exemple d'un tablier de volet roulant, dispositif d'entraínement comportant au moins un moteur caractérisé en ce que de chaque côté du tablier, un moteur entraíne en rotation un axe de commande vertical qui transmet par une pluralité de pièces de renvoi le mouvement à un système de pièces de liaison, elles-mêmes aptes à faire pivoter de façon sélective des lamesThis object is achieved by the invention which consists of a drive device for the selective rotation of the blades of an apron for example of a shutter apron rolling, drive device comprising at least one motor characterized in that on each side of the deck, a motor rotates a control axis vertical which transmits the movement to a system of connecting pieces, themselves capable of pivoting selectively blades

De façon préférentielle les pièces de liaison appelées grandes semelles sont solidaires des pièces de renvoi et présentent une forme générale de portion de rail de guidage.Preferably, the connecting pieces called large soles are integral with the deflection pieces and have a general shape of a rail portion guide.

De façon préférentielle les pièces de liaison appelées (petite semelle, axe médian, bouchon) forment un système de liaison assurant les fonctions de coulissement vertical du tablier et de transmission de mouvement de rotation des pièces de renvoi vers les lames.Preferably the connecting pieces called (small sole, axle median, plug) form a connecting system ensuring the functions of vertical sliding of the deck and transmission of rotational movement of return pieces to the blades.

De façon préférentielle une petite semelle plate et allongée et apte à coulisser dans une grande semelle, est solidarisée à une extrémité d'un axe médian terminé par un bouchon apte à se déplacer dans la cavité d'une lame.Preferably a small flat and elongated sole capable of sliding in a large sole, is secured to one end of a finished median axis by a plug capable of moving in the cavity of a blade.

De façon préférentielle les petites semelles sont déboítables des axes médians.Preferably the small soles are removable from the median axes.

L'invention porte également sur un volet roulant du type comportant un tablier formé d'une succession de lames accrochées et articulées les unes aux autres caractérisé en ce qu'il comporte une pluralité de lames composées de trois parties à savoir une lame médiane pivotante et deux parties distales de part et d'autre de la partie médiane, les parties distales présentant en bordure supérieure une languette d'accrochage se verrouillant dans une gorge de la bordure inférieure de la partie distale immédiatement au-dessus, les parties médianes étant des lames simples et caractérisé en ce que les parties distales sont aptes à coopérer avec les systèmes de liaison du dispositif d'entraínement.The invention also relates to a rolling shutter of the type comprising an apron formed of a succession of blades hung and articulated to each other characterized in that it comprises a plurality of blades composed of three parts to know a pivoting middle blade and two distal parts on either side of the middle part, the distal parts having a tongue at the upper edge hooking locking in a groove in the lower edge of the part distal immediately above, the middle parts being simple blades and characterized in that the distal parts are able to cooperate with the systems connecting the drive device.

De façon préférentielle, un volet roulant comporte un boítier de chaque côté, s'étendant sur toute la hauteur du volet, avec une partie fixe et une partie ouvrante, la partie fixe comportant deux parois portantes parallèles aptes à recevoir des paliers et des pièces de renvois.Preferably, a rolling shutter has a box on each side, extending over the entire height of the shutter, with a fixed part and an opening part, the fixed part comprising two parallel bearing walls capable of receiving bearings and parts of references.

On se rapporte d'abord aux figures 1 et 2.We first refer to Figures 1 and 2.

De chaque côté du tablier du volet un moteur, non représenté, entraíne en rotation et en prise directe un axe de commande (1) vertical qui transmet, par une pluralité de pièces cylindriques de renvoi (2), le mouvement à des pièces de liaisons détaillées plus loin, elles-mêmes aptes à faire pivoter de façon sélective les lames (3).On each side of the shutter of the shutter a motor, not shown, drives rotation and in direct engagement a vertical control axis (1) which transmits, by a plurality of cylindrical return pieces (2), movement to connecting pieces detailed later, themselves capable of selectively rotating the blades (3).

Les figures 3 et 4 montrent un boítier latéral (4) en coupe, qui s'étend sur toute la hauteur du volet et se fixe sur un mur ou sur un montant d'une fenêtre, d'une porte ou autre ouverture.Figures 3 and 4 show a side housing (4) in section, which extends over all the height of the shutter and is fixed on a wall or on the upright of a window, a door or other opening.

Un volet comporte un tel boítier (4) de chaque côté. Un boítier (4) est un profilé par exemple en aluminium extrudé, avec une partie fixe (4a) et une partie ouvrante (4b) pour permettre la maintenance et l'entretien des pièces de liaison contenues à l'intérieur.A flap has such a housing (4) on each side. A housing (4) is a profile for example in extruded aluminum, with a fixed part (4a) and an opening part (4b) to allow the maintenance and upkeep of the connecting parts contained in the interior.

La partie fixe (4a) comporte deux parois essentielles à savoir deux parois portantes (4c) et (4d) parallèles et perpendiculaires au plan du volet, et comportant chacune des pluralités de trous alignés (5) et (6) aptes à recevoir les deux paliers (7) et (8) de chaque pièce de renvoi (2) et à porter chaque pièce de renvoi horizontalement dans le plan du volet. Un circlips non représenté et placé dans une gorge (10), vient bloquer la pièce de renvoi (2).The fixed part (4a) has two essential walls, namely two walls load-bearing (4c) and (4d) parallel and perpendicular to the plane of the shutter, and comprising each of the plurality of aligned holes (5) and (6) suitable for receiving the two bearings (7) and (8) of each return piece (2) and to wear each return piece horizontally in the plane of the shutter. A circlip not shown and placed in a groove (10), blocks the deflection piece (2).

Les figures 2, 5, 6, montrent une des pièces de liaison appelée grande semelle (9) solidaire du palier intérieur (8) de la pièce de renvoi (2). Figures 2, 5, 6 show one of the connecting pieces called the large sole (9) integral with the inner bearing (8) of the deflection piece (2).

Une grande semelle (9) a une forme générale de portion de rail de guidage avec ses deux ouvertures d'extrémités (9a),(9b) évasées et une rainure intérieure de guidage (11) s'étendant verticalement dans le plan d'obturation du volet.A large sole (9) has the general shape of a guide rail portion with its two end openings (9a), (9b) flared and an internal groove guide (11) extending vertically in the shutter closing plane.

Une rainure intérieure (11) est destinée à recevoir une pièce de liaison appelée petite semelle (12) (figures 2 et 7), plate et allongée, de dimensions appropriées pour pouvoir entrer par coulissement dans la rainure intérieure (11), et sans jeu pour pouvoir pivoter avec la grande semelle (9).An internal groove (11) is intended to receive a connecting piece called small sole (12) (Figures 2 and 7), flat and elongated, of appropriate dimensions to be able to slide into the internal groove (11), and without play to be able to pivot with the large sole (9).

De préférence, pour favoriser l'entrée de la petite semelle dans la grande semelle, la petite semelle est biseautée à ses deux extrémités.Preferably, to encourage the entry of the small sole into the large sole, the small sole is bevelled at both ends.

Chaque petite semelle (12) est solidarisée à une extrémité d'un axe médian (13) (figures 2, 3, 7) et perpendiculairement à celui-ci, l'autre extrémité dudit axe médian (13) étant terminée par un bouchon (14) plat et perpendiculaire audit axe.Each small sole (12) is secured to one end of a median axis (13) (Figures 2, 3, 7) and perpendicular to it, the other end of said axis median (13) being terminated by a flat plug (14) and perpendicular to said axis.

La forme et les dimensions du bouchon (14) sont prévues pour qu'il se place à l'intérieur de la cavité d'une pièce d'une lame (3) décrite ci-après.The shape and dimensions of the plug (14) are provided so that it fits the interior of the cavity of a part of a blade (3) described below.

Une lame (3) pour volet roulant, du type de celle représentée sur les figures, est composée de trois parties à savoir une lame médiane (3a) pivotante et deux parties distales (3b) de part et d'autre de la partie médiane (3a).A blade (3) for a roller shutter, of the type shown in the figures, is composed of three parts, namely a pivoting middle blade (3a) and two parts distal (3b) on either side of the middle part (3a).

Les parties distales présentent un profil et une section verticale classique dans le domaine du volet roulant avec en bordure supérieure une languette d'accrochage (15) se verrouillant dans une gorge (17) de la bordure inférieure de la partie distale immédiatement au-dessus (figures 1 et 9).The distal parts have a classic profile and vertical section in the area of the roller shutter with a hanging tab at the top edge (15) locking in a groove (17) of the lower edge of the distal part immediately above (Figures 1 and 9).

Toutes les lames du volet sont ainsi accrochées et articulées les unes aux autres par ce système à gorges (17) et languette (15), prévu sur chaque bordure longitudinale du tablier du volet roulant, lui assurant continuité et souplesse et permettant son enroulement.All the shutter blades are thus hooked and hinged to each other. others by this grooved (17) and tongue (15) system, provided on each edge longitudinal of the roller shutter deck, ensuring continuity and flexibility and allowing its winding.

Les parties médianes (3a) sont des lames simples sans bordures d'accrochage de manière à pouvoir pivoter autour de leur axe longitudinal, une de leur face est recouverte au moins en partie par un miroir ou autre matériau réfléchissant.The middle parts (3a) are simple blades without hooking edges so as to be able to pivot around their longitudinal axis, one of their faces is covered at least in part by a mirror or other reflective material.

En outre les parties distales (3 b) comportent un trou central transversal (16) servant de logement à l'axe médian (13), ledit axe médian étant en deux parties emboítables par des moyens d'emboítement (18) (voir figure 7) pour permettre le montage et le démontage des petites semelles à gauche ou à droite du volet au choix de l'installateur ou de l'installation.Furthermore, the distal parts (3b) have a transverse central hole (16) serving as a housing for the median axis (13), said median axis being in two parts nestable by nesting means (18) (see FIG. 7) to allow the assembly and disassembly of the small soles to the left or right of the flap at choice of installer or installation.

On décrit à présent le fonctionnement du dispositif qui est commandé par un système de pilotage.We now describe the operation of the device which is controlled by a steering system.

Translation du volet (figure 2) Translation of the shutter (figure 2)

Les lames étant en état de fermeture au moyen d'un guide fixé en haut de la porte (4b) pour placer les petites semelles à la verticale et les grandes semelles étant positionnées verticalement, le tablier du volet peut être monté ou descendu à la hauteur voulue.The blades being closed by means of a guide fixed at the top of the door (4b) for placing small soles vertically and large soles being positioned vertically, the shutter curtain can be raised or lowered the desired height.

Les petites semelles coulissent verticalement dans les grandes semelles qui forment un rail de guidage discontinu de chaque côté du volet.The small soles slide vertically in the large soles which form a discontinuous guide rail on each side of the flap.

La distance entre deux grandes semelles (9) successives est calculée pour permettre un déboítement des lames centrales et leur rotation.The distance between two successive large flanges (9) is calculated for allow a dislocation of the central blades and their rotation.

Pivotement des lames médianes (3a) (figure 1). Pivoting of the middle blades (3a) (Figure 1).

Le volet est arrêté à la hauteur désirée, une partie des lames (3) est descendue dans les rails de guidage discontinus formés par les grandes semelles.The shutter is stopped at the desired height, part of the blades (3) is lowered in discontinuous guide rails formed by large flanges.

Dans cette position arrêtée, l'alignement axial des axes de grandes semelles et des petites semelles est réalisée manuellement ou automatiquement, et les parties centrales (3a) des lames sont toutes verticales, une partie d'entre elles peut être reliée aux grandes semelles de droite par un système de liaison (bouchon, axe médian, petite semelle ou bien une partie d'entre elles peut être reliée aux grandes semelles de gauche, ou bien une partie d'entre elles n'est reliée ni à gauche ni à droite ceci au choix de l'utilisateur (figure 1 par exemple).In this stopped position, the axial alignment of the axes of large soles and small soles is made manually or automatically, and the parts central (3a) of the blades are all vertical, some of them can be connected to the large soles on the right by a connection system (plug, axle mid, small sole or part of them can be connected to large soles on the left, or part of them is connected neither to the left nor to right this at the user's choice (figure 1 for example).

Lorsqu'on commande un axe de pivotement (1), celui-ci transmet son mouvement aux pièces de renvoi (2), puis aux grandes semelles (9) qui lui sont associées ce qui entraíne la rotation des parties centrales (3a) reliées aux dites grandes semelles.When a pivot axis (1) is controlled, it transmits its movement to the return pieces (2), then to the large soles (9) which are attached to it associated which causes the rotation of the central parts (3a) connected to said large soles.

La forme des rainures de guidage des grandes semelles recentre automatiquement les petites semelles (12) et les entraíne en rotation.The shape of the guide grooves of the large soles refocuses automatically the small soles (12) and drives them in rotation.

Les parties distales (3b) des lames restent verticales tandis que les parties médianes (3a) sont entraínées en pivotement par les bouchons (14) solidaires des axes médians (13) et des petites semelles (12).The distal parts (3b) of the blades remain vertical while the parts medians (3a) are pivotally driven by the plugs (14) integral with the median axes (13) and small soles (12).

Les systèmes de liaison (bouchon, axe médian, petite semelle) étant déboítables l'utilisateur peut aisément les déplacer et modifier la sélection des lames à faire pivoter.The connection systems (plug, centerline, small sole) being The user can easily move them and modify the selection of blades to rotate.

Le système d'entraínement sélectif selon l'invention est transposable aux tabliers non enroulables (stores, affiches animées) dont les lames sont des lames simples (3a) sans parties distales (3b).The selective drive system according to the invention can be transposed to non-rollable aprons (blinds, animated posters) whose blades are blades simple (3a) without distal parts (3b).

  • diminution des frottements et suppression des couples,
  • motorisation plus faible pouvant de ce fait être intégrée dans les boítiers,
  • faible largeur des bandes latérales non pivotantes formées par les parties distales, donc faible réduction de l'espace d'ouverture,
  • suppression des coincements et des casses,
  • entretien et réparations facilités par les boítiers ouvrants.
Among the advantages of the invention compared to the prior art, we note in particular
  • reduced number of rooms,
  • lower manufacturing and assembly costs,
  • number of tolerances reduced to one (between large and small sole)
  • reduction of friction and elimination of couples,
  • weaker motorization which can therefore be integrated in the housings,
  • small width of the non-pivoting lateral bands formed by the distal parts, therefore small reduction in the opening space,
  • removal of jams and breakages,
  • maintenance and repairs facilitated by the opening boxes.
