Description

L'invention concerne un actionneur d'entraînement d'un store à lames orientables. L'invention trouve donc son application dans le domaine des stores vénitiens disposés à l'intérieur ou à l'extérieur des bâtiments, pour la protection solaire.The invention relates to a drive actuator of a blind with adjustable blades. The invention therefore finds application in the field of venetian blinds arranged inside or outside buildings for sun protection.

FR-A-2 957 966 , WO-A-2012/037 447 , US-A-2008/0262637 et CH-A-691 131 divulguent chacun un exemple d'actionneur d'entraînement d'un store à lames orientables. FR-A-2 957 966 , WO-A-2012 / 037,447 , US-2008/0262637 and CH-A-691 131 each discloses an example of drive actuator of a blind with adjustable blades.

De manière connue sur les stores vénitiens, un premier enrouleur permet de remonter ou d'abaisser les lames du store et un deuxième enrouleur ou poulie a pour fonction d'orienter les lames, l'orientation des lames permettant de régler la luminosité à l'intérieur de la pièce. Le premier enrouleur agit sur un cordon d'élévation, attaché à une barre de charge et le deuxième enrouleur agit sur un cordon d'orientation relié aux lames. Le premier et le deuxième enrouleurs sont disposés dans un basculateur commun, entraîné par un arbre de sortie d'un actionneur du store. Lors d'une rotation de l'arbre de sortie, les deux enrouleurs sont donc entraînés en rotation. Lorsque les lames sont orientées dans une position extrême, c'est-à-dire complètement fermées, le cordon d'orientation se met à glisser sur le deuxième enrouleur. Par conséquent, lorsque l'opérateur descend le store, les lames du store sont toutes fermées. La personne se retrouve alors dans la pénombre tant que les lames n'ont pas été réorientées, manuellement ou automatiquement une fois le store descendu. Le couplage entre la fonction d'enroulement des lames et la fonction d'orientation des lames crée donc un inconfort à l'utilisation. Des solutions à ces problèmes sont connues, notamment par le biais de basculateurs plus évolués, comprenant notamment un dispositif de renvoi d'angle qui permet de mettre en rotation un arbre en parallèle et d'agir plus indépendamment sur l'orientation des lames. Ce dispositif de renvoi d'angle est, par exemple, un engrenage, ou un système de friction par ressort. Ainsi, lorsque l'opérateur commence à replier ou à dérouler le store, le dispositif de renvoi d'angle s'active et les lames s'orientent. Cela impose de concevoir des basculateurs complexes et coûteux, incluant un dispositif de renvoi d'angle, qui ne s'adaptent pas nécessairement aux actionneurs du marché.In known manner on the venetian blinds, a first winder can raise or lower the blades of the blind and a second winder or pulley has the function of orienting the blades, the orientation of the blades to adjust the brightness to the inside the room. The first winder acts on a lifting cord, attached to a load bar and the second winder acts on an orientation cord connected to the blades. The first and second winders are arranged in a common rocker, driven by an output shaft of a blind actuator. During a rotation of the output shaft, the two reels are rotated. When the blades are oriented in an extreme position, i.e. completely closed, the orientation cord begins to slide on the second reel. As a result, when the operator moves down the blind, the awning blades are all closed. The person is then in the dark until the blades have been reoriented, manually or automatically once the blinds down. The coupling between the winding function of the blades and the orientation function of the blades therefore creates discomfort in use. Solutions to these problems are known, in particular through more advanced rockers, including in particular a deflection device which makes it possible to rotate a shaft in parallel and to act more independently on the orientation of the blades. This angle return device is, for example, a gear, or a spring friction system. Thus, when the operator begins to fold or unroll the awning, the bevel gear activates and the blades are oriented. This requires the design of complex and expensive rockers, including a device of return angle, which do not necessarily adapt to the actuators of the market.

Pour pallier ces inconvénients, on peut envisager d'utiliser des stores comportant deux moteurs alimentant chacun un arbre d'entraînement différent, à savoir un arbre d'entraînement dédié au déroulement du store et un arbre d'entraînement dédié à l'orientation des lames. Cependant, ce type de store serait très lourd et peu compact puisqu'il intègrerait un moteur supplémentaire et ajouterait de l'encombrement au niveau du caisson horizontal. Cela empêcherait donc d'ajouter des composants dans le caisson horizontal et limiterait l'ajout de nouvelles fonctionnalités pour le store.To overcome these drawbacks, it is conceivable to use blinds comprising two motors each feeding a different drive shaft, namely a drive shaft dedicated to the unwinding of the blind and a drive shaft dedicated to the orientation of the blades. . However, this type of awning would be very heavy and not very compact since it would incorporate an additional motor and add space at the level of the horizontal box. This would prevent adding components to the horizontal box and limit the addition of new features for the blind.

C'est à ces inconvénients qu'entend plus particulièrement remédier l'invention en proposant un actionneur qui rende le store plus compact et plus ergonomique.It is these drawbacks that the invention intends to remedy more particularly by proposing an actuator that makes the blind more compact and more ergonomic.

A cet effet l'invention concerne un actionneur d'entraînement d'un store à lames orientables, cet actionneur comprenant un boîtier à l'intérieur duquel est disposé un moteur entrainant un premier arbre de sortie qui dépasse de part et d'autre du boîtier, caractérisé en ce que l'actionneur comprend en outre un deuxième arbre de sortie dont l'axe de rotation est parallèle et non confondu avec celui du premier arbre de sortie et des moyens d'accouplement commandés permettant de transmettre sélectivement un mouvement de rotation du premier arbre de sortie au deuxième arbre de sortie et en ce que le deuxième arbre de sortie dépasse de part et d'autre du boîtier.For this purpose the invention relates to a drive actuator of a blind with adjustable blades, this actuator comprising a housing inside which is arranged a motor driving a first output shaft which protrudes from both sides of the housing , characterized in that the actuator further comprises a second output shaft whose axis of rotation is parallel and not coincident with that of the first output shaft and controlled coupling means for selectively transmitting a rotational movement of the output shaft. first output shaft to the second output shaft and in that the second output shaft protrudes from both sides of the housing.

Grâce à l'invention, il est possible de découpler la fonction liée au réglage de la hauteur du store et la fonction liée à l'orientation de ses lames. Ainsi, il est possible de descendre ou de remonter le store en bloquant l'orientation des lames. De plus, l'intégration de moyens de découplage dans l'actionneur rend le store plus compact et adaptable à tout type de store vénitien. L'installation est elle-même facilitée car tous les éléments commandables électriquement se trouvent à proximité les uns des autres, dans le boîtier de l'actionneur. Ils peuvent être pilotés par une même unité de commande.Thanks to the invention, it is possible to decouple the function related to the adjustment of the height of the blind and the function related to the orientation of its blades. Thus, it is possible to go down or up the blind blocking the orientation of the blades. In addition, the integration of decoupling means in the actuator makes the blind more compact and adaptable to any type of venetian blind. The installation itself is facilitated because all the electrically controllable elements are close to each other, in the housing of the actuator. They can be controlled by the same control unit.

  • The first drive shaft and the second drive shaft each drive at least one winder integrated in one of the shutters of the blind, these rockers being arranged on each side of the actuator.

L'invention sera mieux comprise et d'autres avantages de celle-ci apparaîtront plus clairement à la lumière de la description qui va suivre d'un mode de réalisation d'un actionneur et d'un store conformes à son principe, donnée uniquement à titre d'exemple et faite en référence aux dessins annexés dans lesquels :

  • la figure 1 est une vue en perspective d'un store conforme à l'invention,
  • la figure 2 est un schéma illustrant le fonctionnement d'un actionneur conforme à l'invention appartenant au store de la figure 1.
The invention will be better understood and other advantages thereof will appear more clearly in the light of the following description of an embodiment of an actuator and a blind according to its principle, given only to by way of example and with reference to the appended drawings in which:
  • the figure 1 is a perspective view of a blind according to the invention,
  • the figure 2 is a diagram illustrating the operation of an actuator according to the invention belonging to the store of the figure 1 .

Sur la figure 1 est représenté un store S conforme à l'invention. Le store S comprend, en partie supérieure, un caisson horizontal 10, à section en forme de U et qui s'étend selon un axe longitudinal X10. En dessous du caisson horizontal 10, sont disposées, avec un intervalle régulier, plusieurs lames 14 dont seules certaines sont représentées à la figure 1. A l'extrémité basse du store est disposée une barre de charge 12 qui permet de remonter ou d'abaisser le store. Pour cela, la barre de charge 12 est reliée, au moyen de cordons 16 à un ou plusieurs premiers enrouleurs situés au niveau du caisson horizontal 10. Dans le cas présent, les premiers enrouleurs sont situés à l'intérieur de deux basculateurs 8 qui sont chacun disposés à une extrémité du caisson horizontal 10, ces enrouleurs n'étant pas visibles sur les figures. Afin d'accéder à la barre de charge 12, les cordons 16 traversent les lames 14 dans des orifices 014 et leur extrémité basse est fixée à la barre de charge 12.On the figure 1 is shown a blind S according to the invention. The blind S comprises, in the upper part, a horizontal box 10, U-shaped section and which extends along a longitudinal axis X10. Below the horizontal box 10 are arranged, with a regular interval, several blades 14, only some of which are shown in FIG. figure 1 . At the low end of the awning is arranged a load bar 12 which can raise or lower the blind. For this, the load bar 12 is connected, by means of cords 16 to one or more first winders located at the level of the horizontal box 10. In this case, the first winders are located inside two rockers 8 which are each disposed at one end of the horizontal box 10, these reels not being visible in the figures. In order to access the load bar 12, the cords 16 pass through the blades 14 into orifices 014 and their lower end is fixed to the load bar 12.

De manière analogue, le store S comprend deux cordons 18 qui sont attachés à chacune des lames 12 et qui sont chacun enroulés autour d'un deuxième enrouleur disposé également à l'intérieur d'un des basculateurs 8. Les cordons 18 forment en effet une boucle en prise avec le deuxième enrouleur faisant office de poulie. Par rotation, le deuxième enrouleur entraîne le déplacement des cordons 18, permettant ainsi d'orienter les lames pour régler la luminosité dans la pièce. Lorsque les lames atteignent leur position fermée, le cordon 18 glisse sur la poulie.Similarly, the blind S comprises two cords 18 which are attached to each of the blades 12 and which are each wrapped around a second winder also disposed inside one of the rockers 8. The cords 18 form indeed a buckle engaged with the second reel acting pulley. By rotation, the second winder causes the cords 18 to move, thus making it possible to orient the blades to adjust the brightness in the room. When the blades reach their closed position, the cord 18 slides on the pulley.

Les premiers et deuxièmes enrouleurs, sont entraînés, au niveau des basculateurs 8, respectivement par des arbres d'entraînement 4 et 6. Les arbres d'entraînement 4 et 6 sont disposés parallèlement l'un par rapport à l'autre le long du caisson 10, c'est-à-dire qu'un axe de rotation X4 du premier arbre d'entraînement 4 est parallèle à un axe de rotation X6 du deuxième arbre de rotation 6 et à l'axe X10, sans être confondu.The first and second winders are driven, at the rockers 8, respectively by drive shafts 4 and 6. The drive shafts 4 and 6 are arranged parallel to each other along the box 10, that is to say that an axis of rotation X4 of the first drive shaft 4 is parallel to an axis of rotation X6 of the second rotation shaft 6 and the axis X10, without being confused.

Chaque basculateur 8 est globalement parallélépipédique de section transversale complémentaire de celle du caisson horizontal 10 et est traversé par deux arbres d'entraînement 4 et 6. Entre les deux basculateurs 8 est disposé un actionneur 2.Each rocker 8 is generally parallelepipedal cross section complementary to that of the horizontal box 10 and is traversed by two drive shafts 4 and 6. Between the two rockers 8 is disposed an actuator 2.

L'actionneur 2 est globalement parallélépipédique et comporte une section transversale complémentaire de celle du caisson horizontal 10. Cela permet une intégration facilitée de l'actionneur dans le caisson 10.The actuator 2 is generally parallelepipedal and has a cross section complementary to that of the horizontal box 10. This allows easy integration of the actuator in the box 10.

Comme il en ressort de la figure 2, l'actionneur 2 comprend un boîtier 20, par exemple un boîtier étanche, dont sortent un premier arbre de sortie 21 et un deuxième arbre de sortie 23 sur une première face latérale 20a qui est la face du boitier 20 située à gauche à la figure 2. Les deux arbres de sortie 21 et 23 sortent également sur une deuxième face latérale 20b qui est la face du boitier 20 opposée à la face 20a et qui est située à droite à la figure 2. Les arbres de sorties 21 et 23 ont respectivement pour axe de rotation X21 et X23, ces axes de rotation X21 et X23 étant parallèles et non confondus. Les arbres de sortie 21 et 23 sont respectivement guidés par rapport au boîtier 20, grâce à des moyens de guidage tels que des paliers ou des roulements étanches, non représentés sur les figures. De plus, les arbres de sortie 21 et 23 sont aptes à entraîner en rotation, respectivement les arbres d'entraînement 4 et 6. Autrement dit, l'axe X21 est confondu avec l'axe X4 et l'axe X23 est confondu avec l'axe X6. Plus précisément, les arbres de sortie 21 et 23 sont respectivement rendus solidaires des arbres d'entraînement 4 et 6 par emmanchement des arbres de sortie 21 et 23 dans les arbres d'entraînement 4 et 6. A cet effet, les arbres d'entraînement 4 et 6 comprennent chacun un manchon de sortie creux, dont la partie creuse est adaptée pour recevoir l'extrémité de l'arbre de sortie correspondant. Ces emmanchements sont représentés à la figure 2 par des croix. Pour ce faire, les arbres de sortie 21 et 23 dépassent axialement de part et d'autre du boîtier 20 de l'actionneur.As is apparent from the figure 2 the actuator 2 comprises a housing 20, for example a sealed housing, from which a first output shaft 21 and a second output shaft 23 extend on a first lateral face 20a which is the face of the housing 20 located on the left at the figure 2 . The two output shafts 21 and 23 also come out on a second lateral face 20b which is the face of the housing 20 opposite the face 20a and which is situated on the right at the figure 2 . The output shafts 21 and 23 respectively have the axis of rotation X21 and X23, these axes of rotation X21 and X23 being parallel and not coincidental. The output shafts 21 and 23 are respectively guided relative to the housing 20 by means of guiding means such as bearings or sealed bearings, not shown in the figures. In addition, the output shafts 21 and 23 are able to drive in rotation, respectively the drive shafts 4 and 6. In other words, the axis X21 coincides with the axis X4 and the axis X23 coincides with the X6 axis. More specifically, the output shafts 21 and 23 are respectively secured to the drive shafts 4 and 6 by fitting the output shafts 21 and 23 in the drive shafts 4 and 6. For this purpose, the drive shafts 4 and 6 each comprise a hollow outlet sleeve, the hollow portion of which is adapted to receive the end of the corresponding output shaft. These joints are represented at figure 2 by crosses. To do this, the output shafts 21 and 23 protrude axially on both sides of the housing 20 of the actuator.

Ainsi, les arbres de sortie 21 et 23 se prolongent, par l'intermédiaire des arbres d'entraînement 4 et 6, jusqu'au niveau des deux basculateurs 8.Thus, the output shafts 21 and 23 extend, via the drive shafts 4 and 6, to the level of the two rockers 8.

A l'intérieur du boîtier 20 est disposé un moteur électrique 22, sachant qu'il peut également s'agir d'un motoréducteur. Le moteur 22 comprend un seul arbre de sortie 220 dont un axe de rotation X220 est parallèle avec celui des arbres de sortie 21 et 23 et qui s'étend vers la première face latérale 20a. Le moteur 22 fait tourner un premier pignon 240 en prise avec un deuxième pignon 242. Le premier pignon 240 et le deuxième pignon 242 ont des dentures extérieures complémentaires l'une de l'autre et forment ensemble un premier engrenage 24. Le deuxième pignon 242 est, quant à lui, solidaire en rotation du premier arbre de sortie 21. Ainsi, la rotation du moteur 22 entraîne la rotation du premier arbre de sortie 21.Inside the housing 20 is disposed an electric motor 22, knowing that it can also be a geared motor. The motor 22 comprises a single output shaft 220 whose axis of rotation X220 is parallel to that of the output shafts 21 and 23 and which extends towards the first lateral face 20a. The motor 22 rotates a first gear 240 in engagement with a second gear 242. The first gear 240 and the second gear 242 have external teeth complementary to each other and together form a first gear 24. The second gear 242 is, meanwhile, integral in rotation of the first output shaft 21. Thus, the rotation of the motor 22 causes the rotation of the first output shaft 21.

Sur le même arbre de sortie 21 et du côté de la face latérale 20b, est disposé un premier pignon 262 solidaire en rotation du premier arbre de sortie 21 et qui coopère avec un deuxième pignon 260. Le deuxième pignon 260 est relié au deuxième arbre de sortie 23 dont l'axe de rotation est parallèle à et non confondu avec celui du premier arbre de sortie 21. Le premier pignon 262 a une denture externe complémentaire de celle du deuxième pignon 260. Ils forment donc un ensemble un deuxième engrenage 26.On the same output shaft 21 and the side of the side face 20b, is disposed a first gear 262 rotatably connected to the first output shaft 21 and which cooperates with a second gear 260. The second gear 260 is connected to the second gear shaft. output 23 whose axis of rotation is parallel to and not coincident with that of the first output shaft 21. The first gear 262 has an external toothing complementary to that of the second gear 260. They thus form a set a second gear 26.

Le deuxième engrenage 26 diffère du premier engrenage 24 dans la mesure où il comprend en outre un embrayage électromagnétique 264 qui connecte, de manière sélective, le pignon 260 à l'arbre 23. Par conséquent, la rotation du deuxième arbre de sortie 23 est obtenue de manière sélective, c'est-à-dire que dans une configuration désaccouplée où l'embrayage électromagnétique 264 n'est pas actif, l'arbre de sortie 23 n'est pas mis en rotation par la rotation du premier arbre de sortie 21.The second gear 26 differs from the first gear 24 in that it further comprises an electromagnetic clutch 264 which selectively connects the gear 260 to the shaft 23. As a result, the rotation of the second output shaft 23 is obtained. selectively, i.e. in an uncoupled configuration where the electromagnetic clutch 264 is not active, the output shaft 23 is not rotated by the rotation of the first output shaft 21 .

A cet effet, l'actionneur comprend une unité électronique 28 de commande de l'embrayage 264 au moyen d'un signal électrique S28. De manière connue, l'unité électronique de commande 28 reçoit un ordre de la part de l'opérateur. Cet ordre est émis, par exemple, grâce à une télécommande non représentée qui émet des signaux de commande sous forme d'ondes radio vers un récepteur 27 comprenant une antenne située dans l'actionneur En fonction de la nature du signal reçu par le récepteur 27, l'unité de commande 28 active ou non l'embrayage électromagnétique grâce au signal S28. Le deuxième arbre de sortie 23 est solidaire en rotation avec une couronne dentelée non représentée et le deuxième pignon 260 comporte, à l'intérieur, des cannelures complémentaires des dentures de cette couronne. Lorsque l'embrayage 264 est désactivé, la couronne dentelée est décalée par rapport au pignon 260 et selon l'axe X23. Dans le cas où l'embrayage 264 est activé, la couronne se déplace par aimantation axialement à l'intérieur du pignon 260. La complémentarité des dentures avec les cannelures implique la rotation du deuxième arbre de sortie 23. L'engrenage 26 forme donc des moyens d'accouplement commandés entre le premier arbre de sortie 21 et le deuxième arbre de sortie 23 et ces moyens d'accouplement sont directement intégrés à l'actionneur 2 et pilotés par l'utilisateur.For this purpose, the actuator comprises an electronic control unit 28 for controlling the clutch 264 by means of an electric signal S28. In known manner, the electronic control unit 28 receives an order from the operator. This command is issued, for example, by means of a remote control, not shown, which transmits control signals in the form of radio waves to a receiver 27 comprising an antenna situated in the actuator Depending on the nature of the signal received by the receiver 27 , the control unit 28 activates or not the electromagnetic clutch through signal S28. The second output shaft 23 is integral in rotation with a not shown notched crown and the second pinion 260 has, inside, complementary grooves of the teeth of this ring. When the clutch 264 is deactivated, the toothed crown is offset relative to the pinion 260 and along the axis X23. In the case where the clutch 264 is activated, the ring moves by magnetization axially inside the pinion 260. The complementarity of the teeth with the splines involves the rotation of the second output shaft 23. The gear 26 forms therefore coupling means controlled between the first output shaft 21 and the second output shaft 23 and these coupling means are directly integrated with the actuator 2 and driven by the user.

Le premier arbre de sortie 21 entraîne le premier arbre d'entraînement 4 et permet de remonter ou d'abaisser le store S, alors que le deuxième arbre de sortie 23 est solidaire du deuxième arbre d'entraînement 6 et permet d'orienter les lames 14, afin de régler la luminosité dans la pièce.The first output shaft 21 drives the first drive shaft 4 and makes it possible to raise or lower the blind S, while the second output shaft 23 is integral with the second drive shaft 6 and allows the blades to be oriented. 14, to adjust the brightness in the room.

Si l'embrayage est activé, l'orientation des lames se fait simultanément à la remontée ou à la descente du store. A l'inverse, il est possible pour l'utilisateur de descendre ou de remonter le store S avec une orientation des lames 14 fixée. Pour ce faire, il convient de désactiver, l'embrayage électromagnétique 264. Le pignon 260 tourne alors librement autour de l'axe X23 sans l'entraîner. L'orientation des lames 14 n'est pas modifiée durant le réglage de la hauteur du store. Ainsi, en partant d'une configuration où les lames 14 sont ouvertes, les lames du store ne sont pas fermées préalablement à la descente du store.If the clutch is activated, the orientation of the blades is simultaneously at the raising or lowering of the blind. Conversely, it is possible for the user to go down or up the blind S with a fixed orientation of the blades 14. To do this, it is necessary to disable the electromagnetic clutch 264. The gear 260 then rotates freely around the axis X23 without driving. The orientation of the blades 14 is not changed during the adjustment of the height of the blind. Thus, starting from a configuration where the blades 14 are open, the awning blades are not closed prior to the descent of the blind.

Par ailleurs, les enrouleurs situés au niveau de l'arbre d'entraînement 6 comportent un système de glissement qui agit lorsque les lames sont arrivées dans une position complètement fermée ou complètement ouverte. Ce système de glissement permet donc à l'arbre d'entraînement 6 de fonctionner en roue libre. Ces systèmes de glissement sont par exemple du même type que ceux décrits précédemment, mettant en oeuvre une boucle du cordon sur un enrouleur de type poulie.Furthermore, the reels located at the drive shaft 6 comprise a sliding system that acts when the blades have arrived in a fully closed or fully open position. This sliding system therefore allows the drive shaft 6 to run freewheel. These sliding systems are for example of the same type as those described above, implementing a cord loop on a pulley type reel.

Le couplage sélectif entre la fonction de remontée/descente du store et la fonction d'orientation des lames de celui-ci implique qu'un mouvement d'orientation des lames du store est basé sur un mouvement de montée ou de descente du tablier. Toutefois, ces mouvements de montée ou de descente du tablier sont peu perceptibles par un utilisateur et ne créent pas d'inconfort. L'utilisation d'un moyen de transmission du mouvement de rotation du premier arbre de sortie 21 au deuxième arbre de sortie 23 par un engrenage implique également que l'orientation des lames 14 se fait dans le sens lié au déplacement du store. En effet, c'est le sens de rotation du premier arbre de sortie 21 qui détermine le sens de rotation du deuxième arbre de sortie 23 et, par conséquent, le sens de l'orientation. Toutefois, les mouvements d'orientation des lames dans les deux sens sont possibles.The selective coupling between the up / down function of the blind and the blade orientation function thereof implies that an orientation movement of the blind blades is based on an upward or downward movement of the deck. However, these movements up or down the apron are not perceptible by a user and do not create discomfort. The use of a transmission means of the rotational movement of the first output shaft 21 to the second output shaft 23 by a gear also implies that the orientation of the blades 14 is in the direction related to the movement of the blind. Indeed, it is the direction of rotation of the first output shaft 21 which determines the direction of rotation of the second output shaft 23 and, therefore, the direction of the orientation. However, the orientation movements of the blades in both directions are possible.

En pratique, il convient d'activer le couplage entre les premier et deuxième arbres de sortie 21 et 23 avant de mettre en rotation le moteur pour éviter de détériorer l'engrenage 26. En effet, durant le réglage de la hauteur du store, un déplacement axial de la couronne dans le pignon 260 est susceptible d'entrainer un mauvais enclenchement des dentures de la couronne dans les cannelures du pignon 260 puisque le pignon 260 est en rotation. Cela aurait pour conséquence une dégradation de l'engrenage 26. Des ordres de commande spécifiques peuvent ainsi être fournis au récepteur et/ou compris par le récepteur de sorte à différencier un ordre de commande de déplacement d'un ordre de commande d'orientation des lames.In practice, it is necessary to activate the coupling between the first and second output shafts 21 and 23 before rotating the motor to avoid damaging the gear 26. In fact, during the adjustment of the height of the blind, a axial displacement of the ring gear in the pinion 260 is likely to cause a bad engagement of the teeth of the ring in the grooves of the pinion 260 since the pinion 260 is rotating. This would result in a degradation of gearing 26. Specific control commands can thus be provided to the receiver and / or understood by the receiver so as to differentiate a shift control command from an orientation control command from the receiver. blades.

La fonction de renvoi d'angle, permettant le dédoublement des axes d'entraînement est intégrée à l'actionneur 2, ce qui permet de s'affranchir de l'utilisation de basculateurs 8 spécifiques et donne plus de souplesse quant à l'adaptation de l'actionneur 2 sur un store quelconque. Les différentes fonctions, comme la réception des ordres de commande, le pilotage des moyens d'accouplement et le pilotage du moteur, gérées par l'unité de commande sont donc également intégrées à l'actionneur ce qui simplifie leur mise au point et l'installation de l'actionneur.The function of return angle, allowing the duplication of the drive axes is integrated with the actuator 2, which makes it possible to overcome the use of specific rockers 8 and gives more flexibility as to the adaptation of the actuator 2 on any blind. The various functions, such as the reception of control commands, the control of the coupling means and the control of the motor, managed by the control unit are therefore also integrated into the actuator which simplifies their development and the installation of the actuator.

En variante non représentée, il est possible d'utiliser un nombre de basculateurs 8 strictement supérieur à deux, l'actionneur étant installé entre deux des basculateurs.In variant not shown, it is possible to use a number of rockers 8 strictly greater than two, the actuator being installed between two rockers.

En variante non représentée, le moteur est un moteur double sortie. Les deux arbres de sortie du moteur correspondent alors au premier arbre de sortie 21 de l'actionneur.In variant not shown, the motor is a double output motor. The two output shafts of the motor then correspond to the first output shaft 21 of the actuator.

Selon une autre variante non représentée, les moyens d'accouplement entre le premier arbre de sortie 21 et le deuxième arbre de sortie 23 diffèrent d'un engrenage, tout en étant commandés par l'utilisateur.According to another variant not shown, the coupling means between the first output shaft 21 and the second output shaft 23 differs from a gear, while being controlled by the user.

Selon une autre variante non représentée, l'arbre d'entraînement 4 et le premier arbre de sortie 21 sont monobloc et l'arbre d'entraînement 6 et le deuxième arbre de sortie 23 sont monobloc.According to another variant not shown, the drive shaft 4 and the first output shaft 21 are monobloc and the drive shaft 6 and the second output shaft 23 are in one piece.

Les caractéristiques des modes de réalisation et variantes décrits ci-dessus peuvent être combinées afin de créer de nouveaux modes de réalisation.The features of the embodiments and variants described above may be combined to create new embodiments.
