Abstract

The tube has alternating section of two different radii, ensuring support of rolled blind and also ensuring grip on the motor drive within the tube. It has a rib formed in its circumference, extending parallel to axis, ensuring support on drive bearing. The tube for carrying the roll of material forming a roller blind comprises a series of alternating first and second channels (7,8). The channels lie alternately around the circumference of the tube and comprise a lower sections (8) which are in contact with the guide bearing (9), and upper sections (7) which are spaced away from the bearing. There may be three pairs of sections, situated at 120 degree intervals around the circumference of the tube. One of the lower sections (8) includes an upward facing notch (12) which enables it to cooperate with a projecting rib (13) on the outside of the guide bearing (9). This structure enables the drive from the motor-reducing gear to be applied to the roller blind support tube.

Description

La présente invention est relative à un dispositif d'entraínement pour tablier de volet roulant ou similaire, le tablier étant mis en mouvement par un groupe moto-réducteur électrique. Elle vise plus particulièrement un tube d'enroulement comportant, d'une part des moyens d'accrochage du tablier sur le tube, et d'autre part un alésage dans lequel s'insère le groupe moto-réducteur électrique.The present invention relates to a device drive for roller shutter deck or similar, the deck being set in motion by a electric gear motor group. It aims more particularly a winding tube comprising, of a part of the means for attaching the apron to the tube, and on the other hand, a bore into which the group is inserted electric gear motor.

De façon classique, pour motoriser un arbre de volet roulant, on vient insérer le moto-réducteur à l'intérieur de l'une des extrémités du tube d'enroulement, le moteur entraínant en rotation le tube d'enroulement dans le sens de la montée ou de la descente.Conventionally, to motorize a shutter shaft rolling, we just insert the gear motor inside from one end of the winding tube, the motor rotating the winding tube in the direction up or down.

La tête du moteur sert généralement de point fixe et est rendue solidaire par des moyens connus aux supports du caisson de volet roulant. Le tube d'enroulement est relié au moteur par l'intermédiaire de deux points précis :

  • au niveau de la partie du palier de guidage, qui peut également servir de bague d'entraínement du système de gestion des fins de course d'arrêts haut et bas,
  • au niveau de l'extrémité du corps du moteur, sur la bague d'entraínement qui transmet le couple de rotation dans un sens ou dans un autre.
The motor head generally serves as a fixed point and is made integral by known means to the supports of the shutter box. The winding tube is connected to the motor via two specific points:
  • at the part of the guide bearing, which can also serve as a drive ring for the management system for the end stops of the top and bottom stops,
  • at the end of the motor body, on the drive ring which transmits the torque in one direction or another.

Les tubes d'enroulement connus de l'art antérieur comportent à l'une de leurs extrémités, une bague d'interface qui s'adapte, d'une part à l'alésage du tube, et d'autre part au profil du palier de guidage. Cette bague de guidage s'indexe sur le palier de guidage qui comporte une saillie en forme de clavette.Winding tubes known from the prior art have a ring at one of their ends interface which adapts, on the one hand to the bore of the tube, and on the other hand to the profile of the guide bearing. This guide ring is indexed on the guide bearing which has a key-shaped projection.

L'un des principaux inconvénients réside particulièrement dans le fait qu'elle crée une surépaisseur de matière entre le palier de guidage du groupe moto-réducteur électrique et le tube d'enroulement.One of the main drawbacks is particularly in the fact that it creates an extra thickness of material between the guide bearing of the geared motor group electric and the winding tube.

En raison de son existence, cette bague impose pour des questions de conception et de résistance mécanique, une épaisseur minimum de pièce. Celle-ci se traduit donc par une épaisseur supplémentaire de matière au niveau du palier de guidage du groupe moto-réducteur et par voie de conséquence, à une augmentation du diamètre du tube d'enroulement du tablier du volet roulant.Due to its existence, this ring imposes for design and mechanical strength issues, a minimum piece thickness. This therefore translates into an additional thickness of material at the level of the guide bearing of the gear motor group and by way of consequence to an increase in the diameter of the tube for rolling up the roller shutter deck.

En fonction des configurations d'intégration de volet roulant au sein de bâtis, que ce soit dans des applications en neuf ou en rénovation, les installateurs et les concepteurs de ce type d'installation ont le souci constant de réduire l'encombrement global du caisson du volet roulant.Depending on the shutter integration configurations rolling within frames, whether in new or renovation applications, installers and the designers of this type of installation are concerned constant to reduce the overall dimensions of the box roller shutter.

En effet, pour une longueur donnée de tablier à enrouler ou à dérouler autour d'un tube, et en fonction de l'épaisseur des lames du tablier, on conçoit aisément que l'encombrement optimal est obtenu pour un diamètre minimum d'enroulement final du tube et des lames du tablier enroulées sur celui-ci, le plus petit possible.Indeed, for a given length of deck to be rolled up or to unwind around a tube, and depending on the thickness of the deck slats, it is easy to see that optimal dimensions are obtained for a diameter minimum final winding of the tube and the blades of the apron rolled up on it, as small as possible.

L'intégration d'une bague d'interface entre le palier de guidage du groupe moto-réducteur électrique et le tube d'enroulement, va à l'encontre de cet objectif. Integration of an interface ring between the bearing guiding the electric geared motor group and the tube winding, goes against this goal.

Une première solution à ce problème consiste à utiliser un tube cylindrique non nervuré et lisse. L'inconvénient de ce type de tube est qu'il ne comporte aucune surface d'accrochage pour transmettre le couple du moteur au tube, la liaison ne pouvant s'effectuer par exemple que par coincement. En outre, il est difficile de solidariser de ces mêmes tubes, les éléments extérieurs au tube qui permettent la liaison au tablier du volet roulant (bague, verrou automatique etc...).A first solution to this problem is to use a smooth, non-ribbed cylindrical tube. Disadvantage of this type of tube is that it has no surface hooking to transmit the engine torque to the tube, the connection being able to take place for example only by jamming. In addition, it is difficult to unite of these same tubes, the elements outside the tube which allow connection to the roller shutter deck (ring, automatic lock etc ...).

Par ailleurs, l'incorporation des moyens de détection nécessaires au fonctionnement des fins de course au sein d'un tube lisse est délicate. En effet, la liaison entre le palier de guidage et le tube oblige à réaliser l'usinage d'une encoche en extrémité du tube de dimension équivalente à la zone en relief en forme de clavette. En outre, la liaison entre la bague d'entraínement et le tube doit pouvoir transmettre le couple de rotation, celle-ci étant réalisée à l'aide de vis ou de rivets nécessitant également des usinages préalables.Furthermore, the incorporation of detection means necessary for the functioning of the limit switches within of a smooth tube is tricky. Indeed, the connection between the guide bearing and the tube means that the machining of a notch at the end of the dimension tube equivalent to the raised area in the shape of a key. In in addition, the connection between the drive ring and the tube must be able to transmit the torque, this being carried out using screws or rivets also requiring prior machining.

La présente invention vise donc à pallier les inconvénients des dispositifs connus de l'art antérieur, en proposant un tube d'enroulement qui ne nécessite pas l'emploi d'une bague d'interface qui garantit le fonctionnement correct des systèmes de fin de course, qui permet l'accrochage de composants annexes du tube d'enroulement, tout en assurant un diamètre d'enroulement final le plus petit possible.The present invention therefore aims to overcome the drawbacks of the devices known from the prior art, by offering a winding tube which does not require the use of an interface ring which guarantees the correct functioning of the limit switch systems, which allows attachment of ancillary components of the tube winding, while ensuring a winding diameter as small as possible.

A cet effet, le tube d'enroulement pour tablier de volet roulant selon l'invention se caractérise en ce qu'il comporte une succession de premières et secondes cannelures alternées selon la circonférence du tube, les parois de fond des secondes cannelures étant en contact d'un palier de guidage d'un moto-réducteur, lesdites cannelures possédant en outre au moins une réservation de matière permettant la coopération avec une zone en relief venue du palier de guidage du moto-réducteur.
D'autres caractéristiques et avantages de la présente invention ressortiront de la description faite ci-après, en référence aux dessins annexés qui en illustrent un exemple de réalisation dépourvu de tout caractère limitatif. Sur les figures :

To this end, the winding tube for a roller shutter curtain according to the invention is characterized in that it comprises a succession of first and second grooves alternated according to the circumference of the tube, the bottom walls of the second grooves being in contact. a guide bearing of a gear motor, said grooves further having at least one reserve of material allowing cooperation with a raised area from the guide bearing of the gear motor.

Selon un mode préféré de réalisation du tube d'enroulement 1 pour tablier de volet roulant ou similaire selon l'invention, celui-ci est élaboré selon un premier mode de réalisation, à partir d'un feuillard métallique d'épaisseur comprise notamment entre 0,5 et 1 mm et dont la largeur correspond sensiblement au périmètre du tube, celui-ci étant mesuré au niveau de son diamètre moyen.According to a preferred embodiment of the tube winding 1 for roller shutter curtain or similar according to the invention, it is developed according to a first embodiment, from a strip metallic with a thickness between 0.5 and 1 in particular mm and whose width corresponds approximately to perimeter of the tube, the latter being measured at its average diameter.

Sur la figure 1, on a représenté schématiquement un tube d'enroulement 1 dans lequel on vient introduire un moto-réducteur électrique comportant un corps, muni à l'une de ses extrémités d'une bague d'entraínement 15 du tube d'enroulement 1, et à son autre extrémité, d'un palier de guidage 9 qui coopère avec le tube 1.In Figure 1, a tube is shown schematically winding 1 into which a gear motor is introduced electric comprising a body, provided with one of its ends of a drive ring 15 of the tube winding 1, and at its other end, a bearing of guide 9 which cooperates with the tube 1.

Deux des parois latérales 2, 3 parallèles du feuillard seront connectées entre elles, au niveau d'un système d'agrafage 4 formé par des lèvres 5 en prise l'une dans l'autre, après avoir subi une pluralité d'opérations de fabrication et d'élaboration (perçage, emboutissage, découpage, formage...) afin de conformer un tube.Two of the side walls 2, 3 parallel to the strip will be connected to each other, at a system level stapling 4 formed by lips 5 engaged one in the other, after having undergone a plurality of operations of manufacturing and development (drilling, stamping, cutting, forming ...) in order to conform a tube.

Ces opérations intermédiaires qui sont réalisées au cours de la transformation du feuillard conformé en plaque jusqu'au feuillard conformé en tube, consistent essentiellement à élaborer des usinages tels que les perçages 6 de profils variés qui autorisent l'accrochage des éléments annexes au tube (verrou d'accrochage du tablier au tube d'enroulement), ainsi que des opérations d'emboutissage qui génèrent des formes en creux et en relief sur la section transversale du tube, l'ensemble de ces opérations étant communément appelé profilage.These intermediate operations which are carried out during of the transformation of the shaped strip into a plate up to the strip shaped into a tube, consist essentially to develop machining such as holes 6 of various profiles which allow hanging elements annexed to the tube (latching hook of the apron to the winding tube), as well as operations stamping which generate hollow shapes and relief on the cross section of the tube, the set of these operations are commonly called profiling.

Ainsi, on réalise le long du périmètre moyen du tube 1, une pluralité de premières et secondes cannelures 7, 8 uniformément réparties sur la circonférence de manière alternée entre les premières et les secondes cannelures. La profondeur des cannelures 8 est conditionnée par le diamètre extérieur du palier de guidage 9 du groupe moto-réducteur électrique (se reporter à la figure 3) et la largeur respective des cannelures 8 est suffisante pour garantir une surface d'appui entre le palier de guidage 9 et le tube 1 qui permette la transmission du couple de rotation transmis par le moto-réducteur électrique, aussi bien à la montée qu'à la descente du tablier du volet roulant.
Selon un premier mode de réalisation, le tube 1 comporte une succession alternée de trois premières et secondes cannelures 7, 8 disposées sensiblement à 120° l'une de l'autre (se référer à la figure 4). Ainsi, par exemple, pour un tube 1 standard de diamètre extérieur de 54 mm, le diamètre intérieur mesuré au fond des cannelures 8 est de 47,5 mm, l'ouverture de ces cannelures 8 mesurée entre les deux parois latérales 10, 11 et le centre du tube 1 correspond sensiblement à un angle de 40°.Thus, along the average perimeter of the tube 1, a plurality of first and second grooves 7, 8 are uniformly distributed over the circumference alternately between the first and the second grooves. The depth of the grooves 8 is conditioned by the outside diameter of the guide bearing 9 of the electric geared motor unit (see FIG. 3) and the respective width of the grooves 8 is sufficient to guarantee a bearing surface between the bearing of guide 9 and the tube 1 which allows the transmission of the torque transmitted by the electric motor-reducer, both when raising and lowering the roller shutter deck.
According to a first embodiment, the tube 1 comprises an alternating succession of three first and second grooves 7, 8 arranged substantially at 120 ° from one another (refer to FIG. 4). Thus, for example, for a standard tube 1 with an outside diameter of 54 mm, the inside diameter measured at the bottom of the grooves 8 is 47.5 mm, the opening of these grooves 8 measured between the two side walls 10, 11 and the center of the tube 1 corresponds substantially to an angle of 40 °.

Selon un deuxième mode de réalisation, le tube 1 comporte une succession alternée d'au moins trois premières et secondes cannelures 7, 8, préférentiellement au nombre de quatre, disposées sensiblement à 90° l'une de l'autre (se référer à la figure 5). Ainsi, pour un tube de diamètre 54 mm, le diamètre intérieur mesuré au fond des cannelures 8 est de 47,5 mm, l'ouverture des cannelures 8 mesurée entre les deux parois latérales 10, 11 et le centre du tube 1 correspond sensiblement à un angle de 30°.According to a second embodiment, the tube 1 comprises an alternating succession of at least three firsts and second grooves 7, 8, preferably the number of four, arranged substantially 90 ° apart ( refer to figure 5). So for a diameter tube 54 mm, the inside diameter measured at the bottom of the splines 8 is 47.5 mm, the opening of the splines 8 measured between the two side walls 10, 11 and the center of tube 1 roughly corresponds to an angle of 30 °.

Quel que soit le mode de réalisation du tube 1 obtenu par profilage d'une feuillard métallique, l'une au moins des premières et secondes cannelures 7 et/ou 8 comporte une réservation 12 en saillie destinée à recevoir une zone en relief 13 formant clavette, réalisée sur le palier de guidage 9 du groupe moto-réducteur électrique.Whatever the embodiment of the tube 1 obtained by profiling of a metal strip, at least one of the first and second grooves 7 and / or 8 has a reservation 12 projecting intended to receive a zone in relief 13 forming a key, produced on the bearing of guide 9 of the electric geared motor group.

En fonction du type de moteur devant être intégré à l'intérieur du tube 1, on prévoit de disposer différents profils de réservation 12 (non représentés sur les figures) sur chacune des premières et secondes cannelures 7 et/ou 8. Ainsi, suivant l'origine du groupe moto-réducteur, l'utilisateur positionne angulairement la zone en relief 13 formée sur le palier de guidage 9 dans la cannelure 7 et/ou 8 qui possède la réservation 12 de profil adapté.Depending on the type of engine to be integrated into inside the tube 1, we plan to have different reservation profiles 12 (not shown on the figures) on each of the first and second grooves 7 and / or 8. Thus, depending on the origin of the geared motor group, the user angularly positions the area in relief 13 formed on the guide bearing 9 in the groove 7 and / or 8 which has reservation 12 of suitable profile.

Selon un deuxième mode de réalisation du tube 1 d'enroulement pour tablier de volet roulant ou similaire selon l'invention, celui-ci est élaboré à partir d'une technique d'extrusion de matière plastique ou métallique au travers d'une filière dont le profil correspond à la section transversale du tube.According to a second embodiment of the tube 1 for rolling shutter apron or the like according to the invention, this is developed from a plastic or metallic extrusion technique through a sector whose profile corresponds to the cross section of the tube.

De manière similaire, la section transversale du tube 1 comporte une pluralité de premières et secondes cannelures 7, 8 uniformément réparties sur la circonférence et dont l'une au moins des cannelures 7 et/ou 8 comporte une réservation 12 dont le profil est adapté à la zone en relief 13 du palier de guidage 9 du groupe moto-réducteur électrique.Similarly, the cross section of the tube 1 has a plurality of firsts and seconds grooves 7, 8 uniformly distributed over the circumference and of which at least one of the grooves 7 and / or 8 includes a reservation 12 whose profile is adapted to the raised area 13 of the guide bearing 9 of the electric gear motor group.

Les zones 14 du tube 1 entre chaque cannelure 8 étant écartées du corps du moteur, celles-ci génèrent un espace libre qui permet le passage des vis de fixation ou des crochets à l'intérieur des trous et lumières 6 pratiqués le long du tube 1.The zones 14 of the tube 1 between each groove 8 being away from the engine body, these generate space free allowing passage of fixing screws or hooks inside the 6 holes and lights along the tube 1.

Si on utilise un mode d'obtention du tube à partir du profilage d'un feuillard, il est nécessaire de connecter entre elles deux des parois latérales 2, 3 parallèles du feuillard.If we use a method of obtaining the tube from profiling of a strip, it is necessary to connect between them two side walls 2, 3 parallel to the strip.

Cette opération est réalisée par la formation, notamment par emboutissage, sur chacune de ces deux parois latérales 2, 3 de lèvres 5 d'agrafage qui viennent lors de l'opération finale de formation du tube, se superposer l'une contre l'autre avant d'être définitivement rendues solidaires, notamment par une opération de sertissage ou de soudage point par point. This operation is carried out through training, in particular by stamping, on each of these two walls side 2, 3 of lips 5 of stapling which come during of the final tube formation operation, overlap one against the other before being definitively returned united, in particular by a crimping operation or point-to-point welding.

La présente invention telle que décrite précédemment offre de multiples avantages car elle permet de monter un groupe moto-réducteur électrique à l'intérieur d'un tube sans recours à une bague d'interface, et les cannelures permettent également de connecter des éléments annexes du système du volet roulant, notamment un système de compensateur pour manoeuvre par tirage direct, un embout pour manoeuvre par sangle, ou un dispositif pour manoeuvre par treuil à manivelle ou à cordon.The present invention as described above offers multiple advantages because it allows you to mount a electric gear motor group inside a tube without the use of an interface ring, and the splines also allow you to connect additional elements of the roller shutter system, including a compensator for direct pull operation, one end for operation by strap, or a device for maneuver by winch with crank or cord.

Il demeure bien entendu que la présente invention n'est pas limitée aux exemples de réalisation décrits et représentés ci-dessus, mais qu'elle en englobe toutes les variantes.Of course, the present invention is not not limited to the embodiments described and shown above, but that it includes all variants.
