Description

DISPOSITIF D'ENTRAINEMENT EN ROTATION ET DE SUPPORT D'UN TUBE D'ENROULEMENT ET INSTALLATION DOMOTIQUE COMPRENANT UN TEL DEVICE FOR DRIVING ROTATION AND SUPPORTING A WINDING TUBE AND DOMOTIC INSTALLATION COMPRISING SUCH
DISPOSITIFDEVICE
La présente invention concerne un dispositif d'entraînement en rotation et de support d'un tube d'enroulement d'un écran mobile utilisé dans une installation domotique, telle qu'un volet roulant ou un store. L'invention concerne également une installation domotique comprenant un tel dispositif.The present invention relates to a device for driving in rotation and supporting a winding tube of a mobile screen used in a home automation system, such as a shutter or blind. The invention also relates to a home automation installation comprising such a device.
Pour qu'un écran s'enroule autour d'un tube, il est nécessaire que celui-ci soit maintenu en position et guidé en rotation autour d'un axe, l'axe d'enroulement. Pour cela, des paliers sont disposés à chaque extrémité du tube. Lorsque le tube est motorisé par un actionneur tubulaire inséré à l'intérieur de celui-ci, une liaison pivot est assurée par une couronne solidaire du tube et montée libre en rotation autour du corps tubulaire de l'actionneur, ce corps étant immobilisé par rapport au bâti. A l'autre extrémité, un embout est habituellement emmanché. Cet accessoire coopère avec un support ou une joue, fixé sur le bâti, de manière à réaliser le deuxième palier. Pour que l'embout positionne le tube et lui assure un bon guidage, une longueur minimum d'emmanchement est indispensable. Ce recouvrement permet de rigidifier la liaison entre ces deux pièces, les rendant ainsi solidaires. Par cette configuration, le poids du tablier exercé sur le tube d'enroulement est correctement repris au niveau des paliers.For a screen to wind around a tube, it is necessary that it is held in position and guided in rotation about an axis, the winding axis. For this, bearings are arranged at each end of the tube. When the tube is motorized by a tubular actuator inserted inside thereof, a pivot connection is provided by a ring integral with the tube and rotatably mounted around the tubular body of the actuator, this body being immobilized relative to to the frame. At the other end, a tip is usually fitted. This accessory cooperates with a support or a cheek, fixed on the frame, so as to achieve the second bearing. So that the tip positions the tube and ensures good guidance, a minimum length of fitting is essential. This overlap makes it possible to stiffen the connection between these two parts, thus making them integral. By this configuration, the weight of the deck exerted on the winding tube is correctly resumed at the bearings.
Pour constituer un ensemble monobloc et unitaire, la demande de brevet FR 2 887 577 décrit un embout ou corps de roulement fixé sur un épaulement formé à chaque extrémité du tube afin de ne pas déborder du diamètre de ce dernier et être en alignement avec ses génératrices. Ainsi, cette demande propose une solution pour améliorer l'enroulement des lames autour du tube grâce à cet alignement des génératrices qui forment une zone continue d'appui des lames. Ceci induit la réalisation d'un épaulement à chaque extrémité du tube, ce qui constitue une opération coûteuse et pas toujours réalisable. Beaucoup de tubes sont des profilés dont la section ne permet pas de réaliser cet épaulement, par exemple polygonale.To form a unitary and unitary assembly, the patent application FR 2 887 577 describes a tip or rolling body fixed on a shoulder formed at each end of the tube so as not to exceed the diameter of the latter and be in alignment with its generators . Thus, this application proposes a solution for improving the winding of the blades around the tube by virtue of this alignment of the generatrices which form a continuous zone of support of the blades. This induces the realization of a shoulder at each end of the tube, which is a costly operation and not always feasible. Many tubes are profiles whose section does not make this shoulder, for example polygonal.
La motorisation de tubes d'enroulement d'écran de faible largeur peut poser des difficultés. En effet, la longueur du tube doit être, préférentiellement, ajustée à la largeur de l'écran. Or, pour ce type d'écrans, la largeur peut être plus petite que la longueur de la partie de l'actionneur tubulaire insérée dans le tube à laquelle on ajoute la longueur minimum d'emmanchement de l'embout. Ainsi, on ne peut pas ajuster la longueur du tube d'enroulement à la largeur de tel écran. Pour résoudre ce problème, le tube peut être motorisé différemment. La gestion de l'alimentation peut être réalisée par une platine indépendante. L'actionneur peut être intégralement logé dans la joue. Pour cela, il faut que l'installation permette de loger la partie externalisée, ce qui, généralement, n'est pas le cas pour ces écrans de faible largeur.The motorization of screen winding tubes of small width can pose difficulties. Indeed, the length of the tube must be, preferably, adjusted to the width of the screen. However, for this type of screen, the width may be smaller than the length of the part of the tubular actuator inserted in the tube to which is added the minimum length of fitting of the tip. Thus, it is not possible to adjust the length of the winding tube to the width of such a screen. To solve this problem, the tube can be motorized differently. Power management can be achieved by an independent board. The actuator can be fully housed in the cheek. For this, it is necessary that the installation allows to house the outsourced part, which, generally, is not the case for these screens of small width.
C'est à ces inconvénients qu'entend plus particulièrement remédier l'invention en proposant un dispositif d'entraînement en rotation et de support d'un tube d'enroulement qui présente une grande compacité axiale et qui est adapté à la commande du déplacement d'un écran de faible largeur.It is to these drawbacks that the invention more particularly intends to remedy by proposing a device for driving in rotation and for supporting a winding tube which has a great axial compactness and which is suitable for controlling the movement of a screen of small width.
A cet effet, l'invention concerne un dispositif d'entraînement en rotation et de support d'un tube d'enroulement d'un écran mobile, ce dispositif comprenant un actionneur tubulaire équipé d'un arbre de sortie, l'actionneur étant inséré dans le tube d'enroulement par une première extrémité de ce tube et apte à entraîner en rotation le tube d'enroulement par l'intermédiaire de l'arbre de sortie, ainsi qu'un embout formant support pour le tube équipé de l'actionneur. Ce dispositif est caractérisé en ce qu'au moins une partie chevauchante de l'embout s'étend axialement, à partir de la deuxième extrémité du tube et en direction de sa première extrémité, jusqu'au niveau d'au moins une partie de l'arbre de sortie.To this end, the invention relates to a device for driving in rotation and for supporting a winding tube of a mobile screen, this device comprising a tubular actuator equipped with an output shaft, the actuator being inserted in the winding tube through a first end of this tube and adapted to drive in rotation the winding tube through the output shaft, and a support endpiece for the tube equipped with the actuator . This device is characterized in that at least one overlapping portion of the nozzle extends axially, from the second end of the tube and towards its first end, to the level of at least a portion of the nozzle. output shaft.
Au sens de l'invention, la partie chevauchante de l'embout est une partie qui s'étend à partir d'une paroi de l'embout obturant le tube, jusqu'à venir en recouvrement total ou partiel de l'arbre de sortie de l'actionneur. Ce recouvrement peut avoir lieu par l'extérieur d'une roue d'entraînement, c'est-à-dire autour de la roue, ou à travers celle- ci. Un gain en longueur du dispositif de l'invention est obtenu parce qu'une partie de l'embout se situe au même niveau axial qu'une partie de l'arbre entraîné par l'actionneur tubulaire. On obtient une zone de recouvrement entre ces deux pièces. Avec cette configuration, il est alors possible de motoriser des tubes d'enroulement de petite longueur correspondant à des écrans de faible largeur. On entend par « petite longueur », une longueur légèrement supérieure ou égale à la longueur de la partie de l'actionneur insérée dans le tube. L'embout participe à la transmission des efforts exercés sur le tube vers le bâti et plus particulièrement, la reprise du poids du tablier. L'embout doit donc être solidaire du tube, ce qui nécessite une longueur minimum d'emmanchement ou de recouvrement de la partie chevauchante de l'embout avec le tube. En agençant la partie chevauchante de manière à ce qu'au moins une partie de l'embout et au moins une partie de l'arbre de sortie de l'actionneur se situent axialement au même niveau, la longueur du tube équipé peut être diminuée de quelques précieux centimètres. L'invention présente principalement un intérêt quand la largeur de l'écran motorisé est inférieure à la longueur résultant de la somme de la longueur de la partie de l'actionneur insérée dans le tube avec la longueur minimum de la partie chevauchante de l'embout. Cette dimension délimite le terme « petite longueur » précédemment défini.Within the meaning of the invention, the overlapping portion of the nozzle is a part that extends from a wall of the nozzle closing the tube, to come in total or partial recovery of the output shaft of the actuator. This overlap can take place by the outside of a drive wheel, that is to say around the wheel, or through it. A gain in length of the device of the invention is obtained because a portion of the nozzle is at the same axial level as a portion of the shaft driven by the tubular actuator. A zone of overlap is obtained between these two parts. With this configuration, it is then possible to motor winding tubes of small length corresponding to screens of small width. By "small length" is meant a length slightly greater than or equal to the length of the part of the actuator inserted in the tube. The tip contributes to the transmission of the forces exerted on the tube towards the frame and more particularly, the recovery of the weight of the deck. The tip must therefore be integral with the tube, which requires a minimum length fitting or covering the overlapping portion of the tip with the tube. By arranging the overlapping portion so that at least a portion of the bit and at least a portion of the output shaft of the actuator are located axially at the same level, the length of the equipped tube can be decreased by precious few centimeters. The invention is of primary interest when the width of the motorized screen is less than the length resulting from the sum of the length of the portion of the actuator inserted in the tube with the minimum length of the overlapping portion of the mouthpiece. . This dimension delimits the term "small length" previously defined.
Pour simplifier l'installation et diminuer le nombre de pièce, l'embout est avantageusement muni d'un pion, appartenant à un palier de supportage de l'arbre d'enroulement.To simplify the installation and reduce the number of parts, the tip is advantageously provided with a pin, belonging to a support bearing of the winding shaft.
Selon un premier aspect avantageux de l'invention, l'arbre de sortie de l'actionneur est solidaire en rotation du tube d'enroulement par l'intermédiaire d'une roue d'entraînement. Dans ce cas, la partie chevauchante de l'embout s'étend avantageusement à l'intérieur du tube jusqu'au niveau de la roue d'entraînement qu'elle recouvre partiellement. Ainsi logé, l'embout ne perturbe pas l'enroulement de l'écran autour du tube dont les formes extérieures sont optimisées à cet effet. On peut en particulier prévoir que la roue d'entraînement définit un espace de réception au moins partiel de la partie chevauchante de l'embout. De façon avantageuse, cet espace de réception est délimité entre des reliefs en saillie radiale de la roue qui sont en prise avec la surface interne du tube d'enroulement. En variante, cet espace est formé par un orifice ménagé dans l'épaisseur de la roue.According to a first advantageous aspect of the invention, the output shaft of the actuator is integral in rotation with the winding tube via a drive wheel. In this case, the overlapping portion of the nozzle advantageously extends inside the tube to the level of the drive wheel which it partially overlaps. Thus housed, the tip does not disturb the winding of the screen around the tube whose outer shapes are optimized for this purpose. In particular, it can be provided that the drive wheel defines an at least partial receiving space of the overlapping portion of the endpiece. Advantageously, this reception space is delimited between radially protruding reliefs of the wheel which are in engagement with the inner surface of the winding tube. In a variant, this space is formed by an orifice formed in the thickness of the wheel.
Une partie de l'embout chevauche au moins une partie de la roue. Celle-ci doit donc permettre ce chevauchement. Elle est donc munie, en vis à vis des parties chevauchantes de l'embout, d'espaces de réception de ces parties chevauchantes.Part of the tip overlaps at least a portion of the wheel. This must therefore allow this overlap. It is therefore provided, facing the overlapping portions of the nozzle, reception spaces of these overlapping parts.
En variante, l'arbre de sortie est solidaire en rotation du tube d'enroulement par l'intermédiaire de l'embout. En d'autres termes, la roue d'entraînement et l'embout précités ne forment qu'une seule et même pièce. Outre la simplification du système par diminution du nombre de pièces, cette solution propose un embout renforcé permettant une bonne transmission de l'effort et un bon alignement de l'axe d'enroulement, entre l'axe de l'actionneur et l'axe du tube d'enroulement. Une autre alternative consiste à ce que l'embout recouvre l'extérieur du tube. Cette solution est adaptée au tube dont les dimensions intérieures sont réduites, ne permettant pas l'utilisation des roues d'entraînement munies d'espaces de réception. Avantageusement, la partie chevauchante reprend la forme extérieure du tube. Cette solution s'adapte facilement à un tube, de type profilé standard, découpé à la longueur souhaitée. Aucune reprise d'usinage du tube n'est nécessaire. Les parties chevauchantes de l'embout peuvent également être disposées dans des rainures longitudinales, internes et/ou externes du tube. Si les dimensions le permettent, la ou les parties chevauchantes disposées dans les rainures externes du tube ne dépassent pas radialement du diamètre extérieur inscrit du tube d'enroulement, ce qui permet de ne pas perturber l'enroulement de l'écran.Alternatively, the output shaft is integral in rotation with the winding tube through the nozzle. In other words, the drive wheel and the aforementioned tip form a single piece. In addition to simplifying the system by reducing the number of parts, this solution offers a reinforced tip allowing a good transmission of the force and a good alignment of the winding axis, between the axis of the actuator and the axis. winding tube. Another alternative is that the tip covers the outside of the tube. This solution is adapted to the tube whose inner dimensions are reduced, not allowing the use of drive wheels provided with receiving spaces. Advantageously, the overlapping portion resumes the outer shape of the tube. This solution easily adapts to a tube, of standard profile type, cut to the desired length. No resumption of machining of the tube is necessary. The overlapping portions of the tip may also be disposed in longitudinal, internal and / or external grooves of the tube. If the dimensions allow, the overlapping portion or portions disposed in the outer grooves of the tube do not radially exceed the inscribed outer diameter of the winding tube, which makes it possible not to disturb the winding of the screen.
Dans tous ces cas, l'embout est solidaire en rotation du tube.In all these cases, the tip is integral in rotation of the tube.
L'invention concerne également une installation domotique qui comprend, entre autres, un dispositif tel que mentionné ci-dessus pour l'entraînement en rotation et le support de son arbre d'enroulement.The invention also relates to a home automation installation which comprises, inter alia, a device as mentioned above for driving in rotation and the support of its winding shaft.

L'invention est applicable a différents types d'écrans enroulables. L'illustration décrite ci-après correspond à un type d'écran, à savoir les volets roulants. Cet exemple est bien entendu non limitatif, l'invention pouvant être adaptée aux autres types d'écrans, notamment aux stores.The invention is applicable to different types of roll-up screens. The illustration described below corresponds to a type of screen, namely shutters. This example is of course nonlimiting, the invention can be adapted to other types of screens, including blinds.
La figure 1 représente un volet roulant 1 motorisé tel qu'il est connu de l'assembler. Les lames 3 du tablier 2 s'enroulent autour d'un tube 10. Le tube est entraîné en rotation par un actionneur tubulaire 20, fixé sur un bâti 60. Un actionneur tubulaire comprend généralement un tube dans lequel sont insérés un motoréducteur d'un coté et un module de contrôle de l'alimentation du motoréducteur à l'autre extrémité. Le motoréducteur se termine par un arbre de sortie faisant saillie du tube de l'actionneur. L'arbre de sortie 21 de l'actionneur transmet un couple moteur à une roue d'entraînement 30 solidaire du tube. Pour pouvoir tourner autour de son axe X-X', le tube est guidé en rotation par deux paliers. Le premier palier est réalisé par l'intermédiaire d'une couronne 40, solidaire du tube et libre en rotation autour du cops tubulaire de l'actionneur. A l'autre extrémité du tube, le palier est formé par le biais d'un embout 50 dont une partie vient s'emmancher à l'intérieur du tube sur une longueur de recouvrement Le. L'embout est muni d'un pion 51 centré sur l'axe X-X' et faisant saillie par rapport à l'extrémité du tube. Le pion s'insère dans un roulement 63 disposé à l'intérieur d'un logement 62 du bâti 61. On note que la longueur du tube Lt doit être supérieure à la somme de la longueur de la partie de l'actionneur insérée dans le tube L3 avec la longueur de recouvrement Le.Figure 1 shows a motorized roller shutter 1 as it is known to assemble. The blades 3 of the apron 2 wind around a tube 10. The tube is rotated by a tubular actuator 20, fixed on a frame 60. A tubular actuator generally comprises a tube into which are inserted a geared motor of a side and a power control unit of the gearmotor at the other end. The gearmotor ends with an output shaft projecting from the actuator tube. The output shaft 21 of the actuator transmits a motor torque to a drive wheel 30 integral with the tube. To be able to turn about its axis X-X ', the tube is guided in rotation by two bearings. The first bearing is made by means of a ring 40, integral with the tube and free to rotate around the tubular body of the actuator. At the other end of the tube, the bearing is formed by means of a tip 50, a part of which is fitted inside the tube over a lap length L e . The tip is provided with a pin 51 centered on the axis XX 'and projecting from the end of the tube. The pin is inserted in a bearing 63 disposed inside a housing 62 of the frame 61. It is noted that the length of the tube L t must be greater than the sum of the length of the part of the actuator inserted in the tube L 3 with the overlap length L e .
Dans les modes de réalisation de l'invention décrits ci-après, les éléments analogues à ceux de l'art antérieur portent des références analogues augmentées de 100, 200, 300, 400 ou 500.In the embodiments of the invention described hereinafter, elements similar to those of the prior art bear analogous references increased by 100, 200, 300, 400 or 500.
Selon un premier mode de réalisation de l'invention, illustré par les figures 2 à 4, un actionneur tubulaire 120 équipé d'une roue 130 d'entraînement et d'une couronne 140 est inséré dans un tube 110 à section polygonale par une première extrémité,111 de ce tube, dans le sens de la flèche F1 à la figure 2. La roue 130, qui est montée sur l'arbre de sortie 121 de l'actionneur 120, permet d'entraîner l'arbre 110 en rotation autour de son axe longitudinal X-X' selon lequel a lieu l'insertion de l'actionneur 120. Le tube 110 tourne autour de l'axe X-X' lors de l'utilisation de l'installation comprenant l'actionneur 120, car l'arbre de sortie 121 entraîne le tube 110 par l'intermédiaire de la roue 130.According to a first embodiment of the invention, illustrated in FIGS. 2 to 4, a tubular actuator 120 equipped with a driving wheel 130 and a ring gear 140 is inserted into a tube 110 with a polygonal section by a first end, 111 of this tube, in the direction of the arrow F 1 in Figure 2. The wheel 130, which is mounted on the output shaft 121 of the actuator 120, is used to drive the shaft 110 in rotation around its longitudinal axis XX 'in which takes place the insertion of the actuator 120. The tube 110 rotates about the axis XX' during use of the installation comprising the actuator 120, because the shaft output 121 drives the tube 110 via the wheel 130.
Par l'autre extrémité 112 du tube 110, un embout 150 est ensuite emmanché à l'intérieur du tube, dans le sens de la flèche F2 qui est opposé à celui de la flèche Fi. L'embout comprend une paroi en forme de disque 152 à partir de laquelle fait saillie un pion 151 de centrage et de supportage. Ce pion joue le rôle d'une partie de palier comme le pion 51 de l'art antérieur. De l'autre coté de la paroi 152, des pattes 153 s'étendent axialement vers le tube 110. Elles sont disposées de manière à ce que la cote radiale de leurs faces externes 154, c'est-à-dire la distance radiale entre ces faces et l'axe X-X', est sensiblement égale à la cote radiale des faces internes complémentaires 114 du tube. Ainsi, les pattes 153 s'appuient sur les faces 114 une fois l'embout 150 emmanché dans le tube. Ce sont les pattes 153 qui solidarisent l'embout avec le tube et permettent la transmission d'effort vers le bâti. L'arrêt axial de l'embout dans le tube est obtenu par contact entre l'extrémité 112 du tube avec un bord radial externe correspondant 155 de la paroi 152.By the other end 112 of the tube 110, a tip 150 is then fitted inside the tube, in the direction of the arrow F 2 which is opposite to that of the arrow Fi. The tip comprises a disk-shaped wall 152 from which a centering and supporting pin 151 protrudes. This peg plays the role of a bearing part as the counter 51 of the prior art. On the other side of the wall 152, lugs 153 extend axially towards the tube 110. They are arranged in such a way that the radial dimension of their external faces 154, that is to say the radial distance between these faces and the axis X-X 'is substantially equal to the radial dimension of the complementary inner faces 114 of the tube. Thus, the tabs 153 rest on the faces 114 once the tip 150 fitted into the tube. These are the tabs 153 which secure the tip with the tube and allow the transmission of force to the frame. The axial stop of the nozzle in the tube is obtained by contact between the end 112 of the tube with a corresponding outer radial edge 155 of the wall 152.
La roue 130 comprend des dents 132 qui s'étendent radialement vers l'extérieur à partir d'un moyeu 131 et viennent en prise avec la surface intérieure du tube 110 afin de l'entraîner en rotation autour de l'axe X-X'. Des espaces E130 sont délimités entre les dents 132, avec une section globalement triangulaire lorsque la roue 130 est engagée dans le tube 110.The wheel 130 includes teeth 132 which extend radially outwardly from a hub 131 and engage the inner surface of the tube 110 to rotate it about the X-X axis. . Spaces E 130 are delimited between the teeth 132, with a generally triangular section when the wheel 130 is engaged in the tube 110.
Les pattes 153 de l'embout 150 chevauchent la roue 130 en étant engagées dans le tube 110 à l'intérieur des espaces E130. En d'autres termes, les pattes 153 s'étendent axialement, le long de l'axe X-X', à partir de la paroi 152 et jusqu'au niveau de la roue 130 en configuration montée de l'actionneur 120 et de l'embout 150 par rapport au tube 110. Comme la roue 130 entoure l'arbre 121 , les pattes 153 chevauchent également cet arbre. En pratique, les pattes 153 chevauchent la roue 130, sur toute sa largeur et la dépassent en direction de l'extrémité 111. Toutefois, les pattes 153 pourraient être plus courtes et ne chevaucher qu'une partie de la roue 130.The tabs 153 of the endpiece 150 overlap the wheel 130 by being engaged in the tube 110 inside the spaces E 130 . In other words, the tabs 153 extend axially along the axis X-X 'from the wall 152 and up to the level of the wheel 130 in the mounted configuration of the actuator 120 and the tip 150 relative to the tube 110. As the wheel 130 surrounds the shaft 121, the tabs 153 also overlap this shaft. In practice, the tabs 153 overlap the wheel 130, over its entire width and protrude towards the end 111. However, the tabs 153 could be shorter and overlap only a portion of the wheel 130.
Préférentiellement, les pattes 153 sont également en contact avec au moins une des faces des espaces E130 délimitées par les dents 132. Selon le mode de réalisation décrit, ce contact est réalisé par les nervures 156 monoblocs avec les pattes 153 et qui viennent en appui contre la zone de jonction 133 entre deux dents 132 adjacentes, dans la partie des espaces Ei30 radialement la plus proche de l'axe X-X', la zone 133 de jonction entre deux dents 132 étant formée par une partie de moyeu 131. De ce fait, la roue 130, le tube 110 et l'embout 150 sont solidarisés en rotation et forment un sous- ensemble rigide. L'axe de rotation X-X' du tube est matérialisé par l'alignement direct de l'actionneur associé avec l'embout. L'effet balourd peut ainsi être limité.Preferably, the tabs 153 are also in contact with at least one of the faces of the spaces E 130 delimited by the teeth 132. According to the embodiment described, this contact is made by the ribs 156 in one piece with the tabs 153 and which bear against the connecting region 133 between two adjacent teeth 132 in the part Ei spaces 30 radially closest to the axis X-X ', the area 133 of junction between two teeth 132 being formed by a portion of Hub 131. As a result, the wheel 130, the tube 110 and the end piece 150 are joined in rotation and form a rigid subassembly. The axis of rotation XX 'of the tube is materialized by the direct alignment of the associated actuator with the tip. The unbalance effect can thus be limited.
Un deuxième mode de réalisation est représenté à la figure 5. Des pattes 253 d'un embout non représenté sont engagées dans des espaces de réception correspondants E230 ménagés dans une roue 230. Les espaces E230 sont formés par des orifices à section circulaire percés selon l'épaisseur de la roue 230, alors que les pattes 253 « chevauchent » la roue 230 en ce sens qu'elles s'étendent axialement jusqu'à elle. Il n'y a pas de contact entre les pattes 253 et le tube d'enroulement 210. Cette solution permet de ne pas être tributaire du profil du tube d'enroulement. L'embout peut être standard pour des tubes ayant différents profils. Seule la roue d'entraînement, qui forme l'interface avec les pattes 253 de l'embout, doit être adaptée à la section du tube 240.A second embodiment is shown in FIG. 5. Lugs 253 of a not shown end-piece are engaged in corresponding receiving spaces E230 formed in a wheel 230. The spaces E230 are formed by circular-section orifices pierced according to FIG. the thickness of the wheel 230, while the tabs 253 "overlap" the wheel 230 in that they extend axially to it. There is no contact between the tabs 253 and the winding tube 210. This solution makes it possible not to be dependent on the profile of the winding tube. The tip may be standard for tubes having different profiles. Only the drive wheel, which forms the interface with the tabs 253 of the nozzle, must be adapted to the section of the tube 240.
Un troisième mode de réalisation de l'invention, illustré à la figure 6, consiste à assembler une seule pièce 350 regroupant les fonctions de la roue et de l'embout du premier mode de réalisation. Cet embout-roue 350 se monte sur l'arbre de sortie 321 de l'actionneur 320. Une partie chevauchante 353 de l'embout 350 recouvre donc partiellement l'arbre de sortie 321. La zone de recouvrement ZR de l'arbre 321 par l'embout-roue 350 est délimitée axialement par la profondeur d'un logement ménagé dans la pièce 350, au centre d'une collerette annulaire 353 qui forme la partie chevauchante, pour recevoir l'extrémité libre de l'arbre 321. En variante, la totalité de l'arbre 321 qui dépasse de l'actionneur 320 peut être reçue dans ce logement. L'embout-roue 350 recouvre alors axialement tout l'arbre 321.A third embodiment of the invention, illustrated in Figure 6, is to assemble a single piece 350 combining the functions of the wheel and the tip of the first embodiment. This wheel tip 350 is mounted on the output shaft 321 of the actuator 320. An overlapping portion 353 of the tip 350 thus partially covers the output shaft 321. The overlap zone Z R of the shaft 321 by the wheel end 350 is delimited axially by the depth of a housing formed in the part 350, in the center of an annular flange 353 which forms the overlapping portion, to receive the free end of the shaft 321. In Alternatively, the entire shaft 321 protruding from the actuator 320 can be received in this housing. The wheel-bit 350 then axially covers the entire shaft 321.
La géométrie interne de la collerette annulaire 353 est adaptée à la géométrie de l'arbre 321 pour permettre une transmission de couple efficace entre l'actionneur 320 et le tube 310. Si l'arbre 321 est à section en étoile ou polygonale, la section interne de la collerette est également en étoile ou polygonale.The internal geometry of the annular flange 353 is adapted to the geometry of the shaft 321 to allow efficient torque transmission between the actuator 320 and the tube 310. If the shaft 321 is a star or polygonal section, the section internal of the collar is also in star or polygonal.
L'embout-roue 350 comprend par ailleurs des formes extérieures s'interfacant avec le profil intérieur du tube 310 de manière à rendre ces deux pièces solidaires en rotation. Enfin, cet embout-roue 350 assure la fonction de palier avec le bâti non représenté, grâce à un pion 351 s'étendant axialement par rapport à l'embout-roue à l'extérieur du tube 310.The wheel end 350 also comprises outer shapes interfacing with the inner profile of the tube 310 so as to make these two parts integral in rotation. Finally, this hub-wheel 350 provides the bearing function with the frame no shown, thanks to a pin 351 extending axially with respect to the wheel end outside the tube 310.
Cette variante induit la contrainte selon laquelle le tube 310 doit avoir une longueur LT3 spécifique, de préférence, légèrement supérieure à une longueur caractéristique LA3 de l'actionneur équipé de cet embout-roue. Cette longueur caractéristique LA3 correspond à la longueur entre la base de la couronne 340 contre laquelle s'appuie le tube 310 et la paroi de l'embout-roue 350 à partir de laquelle s'étend le pion 351. Pour cette variante, l'embout-roue 350 est tout d'abord assemblé sur l'actionneur 320. Ce dernier est ensuite inséré dans le tube 310 par une de ses extrémités 311. Le tube 310 a été préalablement coupé à longueur LT3 de manière à ce que la partie palier de l'embout-roue dépasse du tube. L'embout-roue n'est pas arrêté axialement.This variant induces the constraint that the tube 310 must have a specific length LT3, preferably slightly greater than a characteristic length LA3 of the actuator equipped with this wheel-end. This characteristic length LA3 corresponds to the length between the base of the crown 340 against which the tube 310 rests against the wall of the wheel endpiece 350 from which the pin 351 extends. For this variant, the wheel end 350 is first assembled on the actuator 320. The latter is then inserted into the tube 310 by one of its ends 311. The tube 310 has previously been cut to length LT3 so that the bearing portion the wheel end protrudes from the tube. The wheel end is not stopped axially.
Un quatrième mode de réalisation, représenté à la figure 7, consiste à emmancher un embout-roue 450 par une première extrémité 412 du tube 410 jusqu'à ce qu'une collerette 459 de l'embout-roue appuie contre l'extrémité du tube. Tout comme le troisième mode de réalisation, l'embout-roue 450 comprend des formes extérieures s'interfacant avec le profil intérieur du tube 410, de manière à rendre ces deux pièces solidaires en rotation, et un pion 451 assurant la fonction de palier avec le bâti non représenté. L'actionneur 420 est ensuite inséré par l'autre extrémité 411. L'actionneur doit être indexé angulairement de manière à ce que son arbre de sortie 421 s'interface avec les formes de reprise de couple complémentaire d'un logement interface 458 de l'embout-roue 450. Le logement 452 est délimité par une collerette annulaire 453 qui entoure l'arbre 421 , c'est-à-dire le chevauche axialement, en configuration montée du dispositif. Le tube 410 a été aussi préalablement découpé à longueur afin que, une fois l'actionneur 420 et l'embout-roue 450 assemblé, l'interface entre l'arbre de sortie et l'embout-roue soit suffisant pour transmettre le couple moteur et assurer la rigidité du sous-ensemble. Ainsi, une partie chevauchante de l'embout 450, qui est formée par la collerette 453, recouvre au moins partiellement l'arbre de sortie 421. Cela implique une contrainte dimensionnelle sur le tube de manière à ce que la longueur LT4 entre l'extrémité 411 et le fond du logement interface 458 de l'embout- roue 450 monté sur le tube 410 soit légèrement supérieure à la longueur LA4 entre la base de la couronne 440 contre laquelle s'appuie le tube 410 et l'extrémité de l'arbre de sortie 421 de l'actionneur 420. Comme dans le troisième mode de réalisation, la géométrie interne de la collerette 453 est adaptée à la géométrie de l'arbre 451.A fourth embodiment, shown in FIG. 7, consists in inserting a wheel end 450 through a first end 412 of the tube 410 until a collar 459 of the wheel end presses against the end of the tube. . Like the third embodiment, the wheel end 450 comprises external shapes interfering with the inner profile of the tube 410, so as to make these two parts integral in rotation, and a pin 451 providing the bearing function with the frame not shown. The actuator 420 is then inserted by the other end 411. The actuator must be angularly indexed so that its output shaft 421 interfaces with complementary torque recovery forms of an interface housing 458. The housing 452 is delimited by an annular flange 453 which surrounds the shaft 421, that is to say the axially overlaps, in the mounted configuration of the device. The tube 410 has also been previously cut to length so that, once the actuator 420 and the wheel-bit 450 assembled, the interface between the output shaft and the wheel-end is sufficient to transmit the driving torque. and ensure the rigidity of the subset. Thus, an overlapping portion of the tip 450, which is formed by the flange 453, at least partially overlaps the output shaft 421. This involves a dimensional constraint on the tube so that the length LT4 between the end 411 and the bottom of the interface housing 458 of the wheel tip 450 mounted on the tube 410 is slightly greater than the length LA4 between the base of the crown 440 against which the tube 410 rests and the end of the shaft output 421 of the actuator 420. As in the third embodiment, the internal geometry of the flange 453 is adapted to the geometry of the shaft 451.
Lorsque les dimensions de la section du tube d'enroulement sont proches du diamètre extérieur du corps de l'actionneur tubulaire, les solutions décrites en référence aux figures 1 à 5 précédemment ne sont pas applicables. En effet, la réalisation d'espaces ou d'orifices dans les faibles épaisseurs de la roue fragiliserait la pièce ou serait impossible par manque de matière. Dans ce cas, un autre mode de réalisation, représenté sur les figures 8 à 10, est utilisé. Un actionneur 520 équipé d'un arbre de sortie 521 et d'une roue d'entraînement 530 est inséré dans un tube d'enroulement 510 de manière classique. A l'autre extrémité 512 du tube 510, un embout 550 est emmanché sur l'extérieur du tube. L'embout 550 comprend une paroi 552 en forme de disque d'où fait saillie un pion de centrage et de supportage 551. De l'autre coté de la paroi 552, une partie chevauchante 553 s'étend axialement vers le tube et entoure le tube en configuration montée du dispositif. La partie chevauchante 553 est disposé de manière à ce que la cote radiale d'une partie de ses faces internes 554 est sensiblement égale à la cote radiale des faces externes complémentaires 514 du tube. Préférentiellement cette partie chevauchante forme une bague fermée entourant le tube. Par cette forme, la partie chevauchante est rigide et permet une bonne transmission du poids vers le bâti de l'installation. La bague formée par la partie chevauchante 553 doit cependant être de faible épaisseur pour ne pas pénaliser l'enroulement de l'écran sur le tube 510. Le profil interne de la partie chevauchante 553 peut reproduire le profil externe du tube 510, ce qui permet de rendre solidaire en rotation l'embout 550 et le tube 510 et d'augmenter le nombre de surfaces d'appui radiales. Comme visible à la figure 10, le tube 510 est équipé de rainures longitudinales 516 dans lesquelles sont engagées des nervures 557 qui appartiennent à la partie chevauchante 553. L'arrêt axial de l'embout 550 est obtenu par contact entre l'extrémité 512 du tube avec le bord radial externe correspondant 555 de la paroi 552. La partie chevauchante 553 s'étend axialement, à partir de l'extrémité 512 et vers l'extrémité opposée par laquelle l'actionneur 520 a été inséré dans le tube 510, jusqu'à entourer la roue 530 d'entraînement de l'arbre 510 qui entoure elle-même l'arbre 521 est solidaire en rotation de cet arbre.When the dimensions of the section of the winding tube are close to the outer diameter of the body of the tubular actuator, the solutions described with reference to Figures 1 to 5 above are not applicable. Indeed, the realization of spaces or orifices in the small thicknesses of the wheel would weaken the room or would be impossible for lack of material. In this case, another embodiment, shown in FIGS. 8 to 10, is used. An actuator 520 equipped with an output shaft 521 and a drive wheel 530 is inserted into a winding tube 510 in a conventional manner. At the other end 512 of the tube 510, a tip 550 is fitted on the outside of the tube. The tip 550 comprises a disk-shaped wall 552 from which a centering and support pin 551 projects. On the other side of the wall 552, an overlapping portion 553 extends axially towards the tube and surrounds the tube. tube in mounted configuration of the device. The overlapping portion 553 is arranged so that the radial dimension of a portion of its inner faces 554 is substantially equal to the radial dimension of the complementary external faces 514 of the tube. Preferably this overlapping portion forms a closed ring surrounding the tube. By this form, the overlapping portion is rigid and allows good weight transmission to the frame of the installation. The ring formed by the overlapping portion 553 must however be thin in order not to penalize the winding of the screen on the tube 510. The internal profile of the overlapping portion 553 can reproduce the external profile of the tube 510, which allows to make the end piece 550 and the tube 510 integral in rotation and to increase the number of radial bearing surfaces. As can be seen in FIG. 10, the tube 510 is equipped with longitudinal grooves 516 in which are engaged ribs 557 which belong to the overlapping part 553. The axial stop of the end piece 550 is obtained by contact between the end 512 of the tube with the corresponding outer radial edge 555 of the wall 552. The overlapping portion 553 extends axially from the end 512 and towards the opposite end through which the actuator 520 has been inserted into the tube 510, until 5 to surround the drive wheel 530 of the shaft 510 which itself surrounds the shaft 521 is integral in rotation with this shaft.
En pratique, comme il ressort de la figure 9, la partie chevauchante 553 entoure la roue 530 sur toute la longueur axiale et dépasse de celle-ci en recouvrant également une partie de l'actionneur 520. Ceci n'est pas obligatoire et la partie chevauchante 553 pourrait venir en recouvrement axial d'une partie seulement de la roue 530.In practice, as is apparent from FIG. 9, the overlapping portion 553 surrounds the wheel 530 over the entire axial length and protrudes from it, also covering a portion of the actuator 520. This is not mandatory and the overlap portion 553 could axially overlap only a portion of the wheel 530.
Une variante à ce mode de réalisation consiste à ce que la partie chevauchante 553 se loge dans des rainures longitudinales du profilé du tube. La partie chevauchante peut donc être constitué de plusieurs pattes s'emmanchant dans ces rainures. La tenue de l'embout est moins bonne que dans le mode de réalisation représenté aux figures 2 à 10 mais l'enroulement de l'écran est amélioré car la partie chevauchante ne dépasse pas radialement le diamètre extérieur inscrit du tube d'enroulement.An alternative to this embodiment is that the overlapping portion 553 is housed in longitudinal grooves of the tube section. The overlapping portion may therefore consist of several legs engaging in these grooves. The holding of the tip is less good than in the embodiment shown in Figures 2 to 10 but the winding of the screen is improved because the overlapping portion does not radially exceed the inscribed outer diameter of the winding tube.
Les différents modes de réalisations ont été illustrés en considérant deux formes de profilé pour le tube d'enroulement. Il est évident que l'invention s'étend à d'autres formes de profilés ainsi qu'à d'autres dimensions. Dans ces cas là, les formes des interfaces entre l'embout, la roue et le tube sont adaptées en conséquence.The various embodiments have been illustrated by considering two shapes of profile for the winding tube. It is obvious that the invention extends to other shapes of profiles as well as other dimensions. In these cases, the shapes of the interfaces between the tip, the wheel and the tube are adapted accordingly.
De même, l'invention couvre également les embouts munis d'un logement dans lequel s'insère un pion lié au bâti, pouvant être disposé sur une joue, par exemple. Le pion et le logement forment le palier de supportage du tube. Cette disposition correspond à la configuration inverse de celle illustrée dans les précédents modes de réalisation.Similarly, the invention also covers the end pieces provided with a housing in which a pin connected to the frame is inserted, which can be arranged on a cheek, for example. The pin and the housing form the support bearing of the tube. This arrangement corresponds to the configuration opposite to that illustrated in the previous embodiments.
Les différents modes de réalisation de l'invention mentionnés ci-dessus peuvent être mis en œuvre dans une installation domotique, notamment un volet roulant, un store ou autres écrans analogues , en étant disposés entre deux parties d'un bâti, comme mentionné ci-dessus au sujet de l'état de la technique, en référence à la figure 1. Dans une telle installation, la longueur axiale du tube d'enroulement peut être réduite compte tenu du faible encombrement axial du dispositif d'entraînement en rotation et de support conforme à l'invention.The various embodiments of the invention mentioned above can be implemented in a home automation installation, in particular a shutter, a blind or other similar screens, being arranged between two parts of a frame, as mentioned above. above in the state of the art, with reference to FIG. 1. In such an installation, the axial length of the winding tube can be reduced in view of the small axial space requirement of the rotation and support drive device. according to the invention.
Les caractéristiques techniques des différents modes de réalisation peuvent être combinées entre elles. The technical features of the various embodiments can be combined with each other.
