  • Such installations are used in particular for shutters offering a secure ventilation position, the slats being spaced apart from each other and being spaced apart from the threshold of the opening.
  • Other blocking mechanisms allow orientation of adjustable slats of a roller shutter, as described in the application EP2226462 or even a projection of the deck in a secant plane to their main unwinding plane, as described in the requests FR2962759 , EP2783063 Where FR2941996 .
  • the blocking mechanisms of such installations are configured so that when moving the motorized screen in a first direction, for example during unwinding, the final slat of the screen, that is to say the slat bottom of the hinged slatted shutter or the load bar of a fabric, enters the blocking mechanism, then, following a reverse movement, in a second direction, blocks in the blocking mechanism.

De telles installations sont notamment utilisées pour des volets offrant une position de ventilation sécurisée, les lames étant écartées les unes des autres et étant écartées du seuil de l'ouverture. D'autres mécanismes de blocage permettent une orientation de lames orientables d'un volet roulant, telle que décrite dans la demande EP2226462 ou encore une projection du tablier dans un plan sécant à leur plan de déroulement principal, telles que décrites dans les demandes FR2962759 , EP2783063 ou FR2941996 .Screen installations or known motorized roll-up elements generally comprise a screen, such as an apron formed of articulated and stackable blades, or else an assembly comprising a canvas and a weighted load bar, the apron being rollable around 'a winding tube located in the upper part of the installation, thanks to motorized drive means or actuator. The final slat, or lower slat located at the lower free end of the apron or canvas load bar, is guided by rails located on either side of an opening to be masked. This lower slat can be moved between a lower extreme position, for example in contact with a threshold of the opening and an upper extreme position, for example at the level of a box in which the screen is rolled up. These installations may also include blocking mechanisms, such as locking means making it possible to maintain the lower slat or the load bar of the screen in a determined position while preventing it from being lifted by breaking or slamming under the actions of the wind. Such installations are used in particular for shutters offering a secure ventilation position, the slats being spaced apart from each other and being spaced apart from the threshold of the opening. Other blocking mechanisms allow orientation of adjustable slats of a roller shutter, as described in the application EP2226462 or even a projection of the deck in a secant plane to their main unwinding plane, as described in the requests FR2962759 , EP2783063 Where FR2941996 .

A cet effet, les mécanismes de blocage de telles installations sont configurés de sorte que lors du déplacement de l'écran motorisé dans un premier sens, par exemple lors du déroulement, la lame finale de l'écran, c'est à dire la lame inférieure du volet à lames articulées ou la barre de charge d'une toile, entre dans le mécanisme de blocage, puis, à la suite d'un mouvement inverse, dans un deuxième sens, se bloque dans le mécanisme de blocage.To this end, the blocking mechanisms of such installations are configured so that when moving the motorized screen in a first direction, for example during unwinding, the final slat of the screen, that is to say the slat bottom of the hinged slatted shutter or the load bar of a fabric, enters the blocking mechanism, then, following a reverse movement, in a second direction, blocks in the blocking mechanism.

Ces différents déplacements sont de préférence effectués de manière motorisée. Un actionneur est généralement placé dans le tube d'enroulement et répond à des ordres émanant d'un utilisateur par l'intermédiaire d'une interface de commande telle qu'une télécommande ou une interface murale. L'actionneur comprend un moteur et un réducteur ainsi qu'une unité électronique de commande comprenant des moyens électriques ou électroniques de gestion du mouvement de l'écran motorisé en fonction des ordres reçus et en fonction d'événements détectés. Ces moyens électriques ou électroniques peuvent, pour ce faire, comprendre des détecteurs ou des capteurs de position, de couple ou de temps de parcours.These different movements are preferably carried out in a motorized manner. An actuator is generally placed in the winding tube and responds to commands emanating from a user via a control interface such as a remote control or a wall interface. The actuator comprises a motor and a reduction gear as well as an electronic control unit comprising electric or electronic means for managing the movement of the motorized screen according to the orders received and according to events detected. These electrical or electronic means may, to do this, comprise position, torque or travel time detectors or sensors.

On connaît par exemple de la demande EP 1 650 625 un procédé d'apprentissage des positions d'un dispositif de verrouillage permettant de gérer automatiquement les manœuvres d'un écran motorisé en fonction des ordres reçus de l'utilisateur. Le procédé d'apprentissage définit plusieurs positions. Une première position correspond à la fin de course haute de l'écran motorisé, une deuxième position correspond à la position dite de verrouillage, une troisième position correspond à la position dans laquelle le mouvement de l'écran motorisé doit être inversé de manière à activer le moyen de verrouillage et une quatrième position correspond à la position dite de déverrouillage en dessous de laquelle il faut se déplacer pour déverrouiller l'écran motorisé.We know, for example, of the demand EP 1 650 625 a method for learning the positions of a locking device making it possible to automatically manage the maneuvers of a motorized screen according to the orders received from the user. The learning process defines several positions. A first position corresponds to the upper end of travel of the motorized screen, a second position corresponds to the so-called locking position, a third position corresponds to the position in which the movement of the motorized screen must be reversed so as to activate the locking means and a fourth position corresponds to the so-called unlocking position below which it is necessary to move to unlock the motorized screen.

Au cours du procédé d'apprentissage, l'installateur procède à l'enregistrement de la valeur d'une position angulaire du tube d'enroulement choisie, dite position d'inversion de rotation enregistrée. Cette position est située, dans le sens de déroulement de l'écran motorisé, au niveau ou au-delà de la troisième position (position d'inversion de rotation). A cet effet, l'utilisateur doit placer la lame inférieure du volet ou la barre de charge de la toile dans une zone repérée par des marquages sur les rails de guidage ou les moyens de verrouillage.During the learning process, the installer proceeds to the recording of the value of an angular position of the winding tube chosen, called recorded position of inversion of rotation. This position is located, in the unwinding direction of the motorized screen, at or beyond the third position (rotation inversion position). For this purpose, the user must place the blade bottom of the shutter or the load bar of the fabric in an area identified by markings on the guide rails or the locking means.

Cependant, cette opération est parfois ardue pour l'utilisateur, qui doit souvent procéder par tâtonnements. De plus, un risque d'erreur de positionnement existe. Enfin, il existe un besoin de conception d'installations d'écran motorisé munies de mécanismes de blocage, dont le réglage et la mise en service ne nécessitent plus ou peu d'intervention humaine.However, this operation is sometimes difficult for the user, who often has to proceed by trial and error. In addition, there is a risk of positioning error. Finally, there is a need to design motorized screen installations provided with blocking mechanisms, the adjustment and commissioning of which no longer require or require little human intervention.

L'invention a pour but de remédier à ces inconvénients en proposant un procédé de réglage d'une installation d'un écran motorisé selon la revendication 1.The object of the invention is to remedy these drawbacks by proposing a method for adjusting an installation of a motorized screen according to claim 1.

Grâce à l'analyse des variations du paramètre lié au mouvement de l'écran motorisé au cours d'un déplacement de l'écran motorisé, on détermine automatiquement une position d'entrée dans le mécanisme de blocage qui pourra servir de position d'inversion de rotation candidate pour l'apprentissage automatique de la position d'inversion de rotation. Ceci permet d'éviter que l'utilisateur ait à placer la lame inférieure du volet ou la barre de charge de la toile dans une zone repérée par des marquages sur les rails de guidage ou le mécanisme de blocage.Thanks to the analysis of the variations of the parameter linked to the movement of the motorized screen during a movement of the motorized screen, an entry position in the locking mechanism is automatically determined which can be used as an inversion position. of rotation candidate for automatic learning of the rotation reversal position. This prevents the user from having to place the lower slat of the shutter or the load bar of the canvas in an area marked by markings on the guide rails or the blocking mechanism.

Selon un mode de réalisation préféré de l'invention, les étapes d'analyse des variations du paramètre et de détermination de la position d'entrée sont mises en œuvre par l'actionneur.According to a preferred embodiment of the invention, the steps of analyzing the variations of the parameter and of determining the input position are implemented by the actuator.

Selon l'invention pour rendre simple la détermination de la position d'entrée dans le mécanisme de blocage, la position d'entrée dans le mécanisme de blocage est obtenue à partir de la détermination d'une position de référence, la position de référence étant associée à la détection d'une valeur maximum locale du paramètre ou à la détection d'une valeur de variation maximum locale du paramètre. Ainsi, le procédé de réglage peut être réalisé entièrement automatiquement, sans intervention d'un installateur ou d'un utilisateur pour définir la position de référence associée au mécanisme de blocage.According to the invention, to make it simple to determine the entry position into the blocking mechanism, the entry position into the blocking mechanism is obtained from the determination of a reference position, the reference position being associated with the detection of a local maximum value of the parameter or with the detection of a local maximum variation value of the parameter. Thus, the adjustment method can be carried out entirely automatically, without the intervention of an installer or a user to define the reference position associated with the locking mechanism.

De préférence, la position d'entrée dans le mécanisme de blocage est obtenue par un décalage d'une valeur prédéterminée à partir de la position de référence. Ce décalage peut notamment être lié à des considérations géométriques du mécanisme de blocage ou de sa localisation dans l'installation.Preferably, the entry position in the blocking mechanism is obtained by an offset of a predetermined value from the position of reference. This offset can in particular be linked to geometric considerations of the blocking mechanism or of its location in the installation.

Ainsi, dans la plupart des installations, lorsque le mécanisme de blocage est situé à proximité de la position de référence, la position d'entrée du mécanisme de blocage pourra être définie à partir de la position de référence repérée automatiquement.Thus, in most installations, when the blocking mechanism is located close to the reference position, the entry position of the blocking mechanism can be defined from the reference position identified automatically.

Selon l'invention, le paramètre est le couple exercé par l'actionneur entraînant en mouvement le tablier dans le deuxième sens de déplacement. Le couple est en effet un paramètre dont les variations peuvent être détectées de façon fiable et simple.According to the invention, the parameter is the torque exerted by the actuator moving the deck in the second direction of movement. The torque is in fact a parameter whose variations can be detected reliably and simply.

De préférence, le couple est déterminé à partir d'une mesure du courant traversant un moteur électrique de l'actionneur.Preferably, the torque is determined from a measurement of the current flowing through an electric motor of the actuator.

Selon un mode de réalisation préféré de l'invention, après les étapes d'analyse des variations du paramètre et de détermination de la position d'entrée dans le mécanisme de blocage et une étape d'enregistrement de la position d'entrée dans le mécanisme de blocage, l'écran motorisé est positionné dans la position d'entrée par un mouvement dans le premier sens de déplacement puis entraîné dans le deuxième sens de déplacement jusqu'à la position bloquée, puis, la séquence suivante est effectuée :

  1. a) l'écran motorisé est entraîné dans premier sens de déplacement du tablier jusqu'à une position d'inversion de rotation candidate décalée par rapport à la position d'entrée dans le mécanisme de blocage,
  2. b) l'écran motorisé est entraîné dans le deuxième sens de déplacement du tablier jusqu'à la position bloquée,
la séquence a), b) étant répétée jusqu'à ce que l'extrémité libre du tablier entraînée dans le premier sens de déplacement du tablier dépasse une position dite position de sortie, au-delà de laquelle le blocage de l'écran motorisé n'est plus activé lorsque l'écran motorisé est entraîné dans le deuxième sens de déplacement du tablier.According to a preferred embodiment of the invention, after the steps of analyzing the variations of the parameter and of determining the entry position in the blocking mechanism and a step of recording the entry position in the mechanism blocking, the motorized screen is positioned in the entry position by a movement in the first direction of movement then driven in the second direction of movement to the blocked position, then the following sequence is carried out:
  1. a) the motorized screen is driven in the first direction of movement of the apron to a candidate rotation reversal position offset from the position of entry into the locking mechanism,
  2. b) the motorized screen is driven in the second direction of movement of the curtain to the locked position,
the sequence a), b) being repeated until the free end of the apron driven in the first direction of displacement of the apron passes a position called the exit position, beyond which the blocking of the motorized screen n is no longer activated when the motorized screen is driven in the second direction of movement of the curtain.

Grâce à la répétition de la séquence a)-b), il est possible de tester des positions d'inversion de rotation candidates différentes de celle ayant été initialement définie par l'analyse des variations du paramètre lié au mouvement de l'écran motorisé. Ainsi, l'on peut choisir parmi les positions candidates celle se trouvant à la fois suffisamment éloignée de la position de sortie et de la position de butée. Ce procédé permet d'affiner les réglages obtenus automatiquement, sans nécessiter non plus d'intervention de l'installateur ou de l'utilisateur.Thanks to the repetition of the sequence a)-b), it is possible to test candidate rotation inversion positions different from that having been initially defined by the analysis of the variations of the parameter linked to the movement of the motorized screen. Thus, it is possible to choose from among the candidate positions that which is both sufficiently far from the exit position and from the stop position. This process makes it possible to fine-tune the settings obtained automatically, without requiring either the intervention of the installer or the user.

Ceci a son importance, car lors des cycles de déplacement et d'inversions de sens dans le mécanisme de blocage, on fait intervenir des détecteurs ou capteurs de couple associés à l'actionneur et dont l'activation nécessite que l'actionneur ait atteint un régime stable ou régime nominal. Cela tient notamment au fait que le couple que doit fournir l'actionneur au démarrage est souvent plus élevé que des seuils prédéfinis caractéristiques d'un obstacle ou d'une arrivée du volet en butée, et/ou au fait que la valeur de détection comparable au seuil est obtenue à partir d'un ensemble de mesures lors du fonctionnement de l'actionneur en régime nominal. Ainsi, un délai allant jusqu'à 500ms peut survenir entre un démarrage de l'actionneur et l'activation des détecteurs de couple de l'actionneur. Par conséquent, il est souhaitable que la position d'inversion de sens enregistrée soit suffisamment éloignée de la position d'arrêt dans le mécanisme de blocage pour éviter que la lame inférieure du volet ne se trouve prématurément en butée dans le mécanisme de blocage alors que l'actionneur est en cours de fonctionnement, la détection de couple n'étant pas encore active ou opérationnelle, et pour éviter que l'actionneur n'exerce ainsi des efforts importants sur le mécanisme de blocage pouvant l'endommager. Le mécanisme de blocage comprend en effet des parties flexibles ou mobiles fragiles si elles sont soumises à des efforts mécaniques importants et/ou répétés.This is important, because during the cycles of displacement and reversal of direction in the locking mechanism, detectors or torque sensors associated with the actuator are brought into play and the activation of which requires that the actuator has reached a steady state or nominal state. This is due in particular to the fact that the torque that the actuator must provide on starting is often higher than the predefined thresholds characteristic of an obstacle or of the arrival of the shutter in abutment, and/or to the fact that the comparable detection value at the threshold is obtained from a set of measurements during operation of the actuator at nominal speed. Thus, a delay of up to 500ms can occur between an actuator start and the activation of the actuator torque sensors. Consequently, it is desirable that the direction inversion position recorded be sufficiently far from the stop position in the blocking mechanism to prevent the lower slat of the shutter from being prematurely in abutment in the blocking mechanism while the actuator is in operation, the torque detection not yet being active or operational, and to prevent the actuator from thus exerting significant forces on the locking mechanism which could damage it. The locking mechanism in fact comprises flexible or mobile parts which are fragile if they are subjected to significant and/or repeated mechanical stresses.

A l'inverse, au cours de la vie du volet, les articulations reliant les lames du tablier peuvent se détendre. De ce fait, si la position d'inversion de sens enregistrée par l'utilisateur se trouve trop proche de la position de sortie du mécanisme de blocage, une partie ou toute la lame inférieure pourrait finir par sortir du mécanisme de blocage. Il est donc également souhaitable de s'assurer que la position d'inversion de sens soit choisie de sorte qu'elle soit suffisamment éloignée de la position de sortie du mécanisme de blocage.Conversely, during the life of the shutter, the joints connecting the slats of the apron can relax. Therefore, if the direction inversion position recorded by the user is too close to the exit position of the locking mechanism, part or all of the lower blade could end up coming out of the locking mechanism. It is therefore also desirable to ensure that the inversion position direction is chosen so that it is sufficiently far from the release position of the locking mechanism.

Par ailleurs, la position d'installation et/ou les dimensions du mécanisme de blocage peuvent être variables et les durées d'activation des détections de couple peuvent également différer d'un actionneur à un autre. Il est donc nécessaire de pouvoir affiner les réglages pour chaque installation.Furthermore, the installation position and/or the dimensions of the blocking mechanism may vary and the activation times of the torque detections may also differ from one actuator to another. It is therefore necessary to be able to fine-tune the settings for each installation.

Selon un mode de réalisation préféré de l'invention, chaque position d'inversion de rotation candidate est enregistrée dans une mémoire d'une unité de commande de l'installation d'écran motorisé.According to a preferred embodiment of the invention, each candidate rotation reversal position is recorded in a memory of a control unit of the motorized screen installation.

De la même manière, les distances entre les positions d'inversion de rotation candidates et la position bloquée sont mises en mémoire. Ces distances peuvent être respectivement associées à la position bloquée et à ces positions d'inversion de rotation candidates. Il est ainsi possible, à partir de ces données mémorisées, de déterminer facilement une position d'inversion de rotation optimale.In the same way, the distances between the candidate rotation reversal positions and the blocked position are stored in memory. These distances can be respectively associated with the blocked position and with these candidate rotation inversion positions. It is thus possible, on the basis of these stored data, to easily determine an optimum rotation reversal position.

Selon un mode de réalisation préféré de l'invention, afin de faciliter l'automatisation de l'itération de la séquence a)-b), chaque position d'inversion de rotation candidate d'une nouvelle itération de la séquence est située à une distance prédéterminée d de la précédente position d'inversion de rotation candidate.According to a preferred embodiment of the invention, in order to facilitate the automation of the iteration of the sequence a)-b), each candidate rotation inversion position of a new iteration of the sequence is located at a predetermined distance d from the previous candidate rotation reversal position.

Selon un mode de réalisation préféré de l'invention, l'interruption de l'itération de la séquence a)-b) est décidée par détection d'une absence d'obstacle lors de l'enroulement de l'écran motorisé au niveau de la position bloquée ou pendant une durée prédéterminée à partir du démarrage de l'enroulement.According to a preferred embodiment of the invention, the interruption of the iteration of the sequence a)-b) is decided by detection of an absence of obstacle during the winding of the motorized screen at the level of the locked position or for a predetermined time from the start of the winding.

De manière à détecter la position bloquée de façon simple et rapide, la valeur de position angulaire du tube d'enroulement correspondant à la position bloquée est déterminée à l'aide d'un détecteur ou capteur de position du tube d'enroulement ou à l'aide d'un compteur de temps.In order to detect the locked position simply and quickly, the angular position value of the winding tube corresponding to the locked position is determined using a detector or position sensor of the winding tube or using a time counter.

De préférence, la position bloquée est enregistrée par une mémoire d'une unité de commande de l'installation d'écran motorisé après détection de la valeur de position angulaire du tube d'enroulement correspondant à la position bloquée.Preferably, the locked position is recorded by a memory of a control unit of the motorized screen installation after detection of the angular position value of the winding tube corresponding to the locked position.

De manière à détecter la position bloquée de façon simple et rapide, la valeur de position angulaire du tube d'enroulement correspondant à la position de sortie est mesurée à l'aide d'un capteur de couple d'entraînement du tablier.In order to detect the locked position simply and quickly, the angular position value of the winding tube corresponding to the output position is measured using a driving torque sensor of the apron.

De préférence, la position de sortie est enregistrée par une mémoire d'une unité de commande de l'installation d'écran motorisé après détection de la valeur de position angulaire du tube d'enroulement correspondant à la position de sortie.Preferably, the output position is recorded by a memory of a control unit of the motorized screen installation after detection of the angular position value of the winding tube corresponding to the output position.

L'invention concerne également une installation d'écran motorisé comprenant un tablier enroulable sur un tube d'enroulement, un actionneur de manœuvre du tube d'enroulement de manière à déplacer le tablier dans un premier sens de déplacement et un deuxième sens de déplacement et au moins un mécanisme de blocage de l'extrémité libre du tablier définissant une position dite bloquée dans le deuxième sens de déplacement du tablier, le blocage n'étant activé dans le deuxième sens de déplacement du tablier que si l'extrémité libre du tablier atteint préalablement au moins une position d'entrée dans le mécanisme de blocage, située au-delà de la position bloquée dans le premier sens de déplacement du tablier, caractérisé en ce qu'elle comprend des moyens matériels et logiciels pour la mise en œuvre du procédé de fonctionnement selon l'invention.The invention also relates to a motorized screen installation comprising an apron that can be rolled up on a winding tube, an actuator for maneuvering the winding tube so as to move the apron in a first direction of movement and a second direction of movement and at least one mechanism for locking the free end of the deck defining a so-called locked position in the second direction of movement of the deck, the blocking being activated in the second direction of movement of the deck only if the free end of the deck reaches beforehand at least one entry position in the locking mechanism, located beyond the locked position in the first direction of movement of the apron, characterized in that it comprises hardware and software means for implementing the method operation according to the invention.

Selon un mode de réalisation préféré de l'invention, de manière à obtenir une ergonomie simple du réglage automatique de l'installation pour l'utilisateur, l'installation comprend en outre un dispositif d'activation d'une fonction de déplacement du tablier commandée par un élément d'activation destiné à être actionné par un utilisateur, par exemple un bouton d'activation, dans lequel l'actionnement de l'élément d'activation permet également le déclenchement des étapes d'analyse des variation du paramètre et de détermination de la position d'entrée dans le mécanisme de blocage.According to a preferred embodiment of the invention, so as to obtain simple ergonomics of the automatic adjustment of the installation for the user, the installation further comprises a device for activating a displacement function of the controlled apron by an activation element intended to be actuated by a user, for example an activation button, in which the actuation of the activation element also allows the triggering of the steps of analysis of the variations of the parameter and of determination of the entry position in the blocking mechanism.

Selon un mode de réalisation préféré de l'invention, toujours afin de simplifier l'ergonomie simple du réglage automatique de l'installation pour l'utilisateur, l'actionnement de l'élément d'activation permet également le déclenchement, après les étapes étapes d'analyse des variations du paramètre et de détermination de la position d'entrée dans le mécanisme de blocage, d'une étape d'enregistrement de la position d'entrée dans le mécanisme de blocage.According to a preferred embodiment of the invention, still in order to simplify the simple ergonomics of the automatic adjustment of the installation for the user, the actuation of the activation element also allows the triggering, after the steps steps analysis of the variations of the parameter and determination of the entry position in the locking mechanism, a step of recording the entry position in the locking mechanism.

De préférence, l'installation d'écran motorisé comprend un capteur de couple d'entraînement de l'écran motorisé.Preferably, the motorized screen installation comprises a motorized screen driving torque sensor.

Une installation d'écran motorisé 1 est représentée à la figure 1. Cette installation comprend un tablier 2, par exemple un tablier de volet roulant composé d'une pluralité de lames articulées 3. De préférence, le tablier 2 est constitué de lames 3 empilables, les lames 3 étant reliées entre elles par des parties ajourées escamotables dès que les lames 3 reposent les unes sur les autres. Le tablier 2 est lié, à une de ses extrémités, dite extrémité supérieure, à un tube d'enroulement 4. A l'autre extrémité libre du tablier 2, dite extrémité inférieure, une lame inférieure 5 est guidée par des rails de guidage disposés de part et d'autre d'une ouverture dans un bâtiment, le tablier 2 étant destiné à recouvrir l'ouverture lorsqu'il est fermé. Le tube d'enroulement 4 est de préférence monté au-dessus de l'ouverture que le tablier 2 est destiné à recouvrir. Le tablier 2 vient de préférence s'enrouler dans un caisson 6 destiné à le protéger.A motorized screen installation 1 is shown in figure 1 . This installation comprises an apron 2, for example a rolling shutter apron composed of a plurality of articulated slats 3. Preferably, the apron 2 consists of stackable slats 3, the slats 3 being interconnected by retractable perforated parts as soon as that the blades 3 rest on each other. The apron 2 is connected, at one of its ends, called the upper end, to a winding tube 4. At the other free end of the apron 2, called the lower end, a lower blade 5 is guided by guide rails arranged on either side of an opening in a building, the apron 2 being intended to cover the opening when it is closed. The winding tube 4 is preferably mounted above the opening that the apron 2 is intended to cover. The apron 2 is preferably rolled up in a box 6 intended to protect it.

L'écran motorisé 1 peut notamment consister en un élément de fermeture, d'occultation ou de protection solaire. Dans l'exemple représenté sur les figures, il s'agit d'un tablier 2 composé de lames articulées 3, mais il pourrait également s'agir d'une toile. Dans ce cas, la lame inférieure 5 est remplacée par une barre de charge. De préférence, le tablier 2 comporte un ensemble de lames empilables reliée les unes aux autres par des parties escamotables et ajourées.The motorized screen 1 may in particular consist of a closing, screening or solar protection element. In the example shown in the figures, it is an apron 2 composed of articulated blades 3, but it could also be a canvas. In this case, the lower blade 5 is replaced by a load bar. Preferably, the apron 2 comprises a set of stackable slats connected to each other by retractable and perforated parts.

Les déplacements du tablier 2 sont commandés par les déplacements de rotation du tube d'enroulement 4, dont l'entraînement est assuré par exemple à l'aide d'un actionneur comprenant par exemple un ensemble motoréducteur tubulaire (non représenté) disposé à l'intérieur du tube d'enroulement 4. L'ensemble motoréducteur comprend notamment un moteur et un réducteur, en particulier un réducteur épicycloïdal. Le moteur peut être de type à courant continu et à balais et collecteur, à courant continu et à commutation électronique (Brushless Direct Current motor en langue anglaise) ou asynchrone. Le moteur est piloté par une unité électronique de commande 7, celle-ci étant également reliée à une interface utilisateur 8 par le biais de laquelle un utilisateur peut commander les mouvements du tablier 2.The movements of the apron 2 are controlled by the rotational movements of the winding tube 4, the drive of which is ensured for example using an actuator comprising for example a tubular geared motor assembly (not shown) disposed at the inside the winding tube 4. The geared motor assembly comprises in particular a motor and a reducer, in particular an epicyclic reducer. The motor can be of the direct current and brush and collector type, direct current and electronically commutated (Brushless Direct Current motor in English) or asynchronous. The motor is controlled by an electronic control unit 7, the latter also being connected to a user interface 8 through which a user can control the movements of the apron 2.

Le tablier 2 peut être déplacé selon un premier sens de déplacement et un deuxième sens de déplacement opposés. Dans les modes de réalisation représentés sur les figures, le premier sens de déplacement est le sens du déroulement du tablier 2 et le deuxième sens de déplacement est le sens de l'enroulement du tablier 2. On notera toutefois que d'autres sens de déplacement pourraient être envisagés pour des configurations d'installation d'écran motorisé différentes, notamment en inversant le sens de l'enroulement et le sens du déroulement.The apron 2 can be moved in a first direction of movement and a second opposite direction of movement. In the embodiments shown in the figures, the first direction of movement is the direction of unwinding of the apron 2 and the second direction of movement is the direction of winding of the apron 2. It will however be noted that other directions of movement could be envisaged for different motorized screen installation configurations, in particular by reversing the direction of winding and the direction of unwinding.

L'interface utilisateur 8 peut être reliée à l'unité de commande 7 par des moyens de communication filaire ou non filaire tels que des ondes radioélectriques ou des rayons infrarouges. L'interface utilisateur 8 comprend par exemple deux touches qui permettent à un utilisateur de commander respectivement un déplacement de l'écran motorisé 1 vers le haut ou vers le bas. Une combinaison de touches permet également de déplacer l'écran motorisé 1 dans une position de blocage, définie plus loin. Dans une variante, l'interface utilisateur comprend une touche spécifique dont l'activation permet le déplacement de l'écran motorisé 1 dans la position de blocage. L'interface utilisateur 8 est par exemple une télécommande portative.The user interface 8 can be linked to the control unit 7 by wired or wireless communication means such as radio waves or infrared rays. The user interface 8 comprises for example two keys which allow a user to respectively control a movement of the motorized screen 1 upwards or downwards. A combination of keys also makes it possible to move the motorized screen 1 into a blocking position, defined later. In a variant, the user interface comprises a specific key whose activation allows movement of the motorized screen 1 into the blocking position. The user interface 8 is for example a portable remote control.

L'unité électronique de commande 7 comprend un ou plusieurs moyens de détection 9 de la variation d'un paramètre lié au mouvement de l'écran motorisé 1. Dans le mode de réalisation illustré ici, l'unité de commande comprend un détecteur ou capteur 10 de position angulaire du tube d'enroulement 4, et un détecteur ou capteur de couple 12 exercé par l'actionneur pour détecter des obstacles et/ou les fins de course. Par détecteur ou capteur de position ou de couple, on entend tout moyen matériel et/ou logiciel de détermination de la position ou du couple. L'unité de commande 7 comprend notamment une unité logique de traitement 14 et une mémoire 16.The electronic control unit 7 comprises one or more means 9 for detecting the variation of a parameter linked to the movement of the motorized screen 1. In the embodiment illustrated here, the control unit comprises a detector or sensor 10 of angular position of the winding tube 4, and a detector or torque sensor 12 exerted by the actuator to detect obstacles and / or limit switches. By position or torque detector or sensor is meant any hardware and/or software means for determining the position or the torque. The control unit 7 notably comprises a logic processing unit 14 and a memory 16.

On notera que dans ce qui suit, on considère que le tablier 2 se déroule vers le bas, notamment sous l'effet de son propre poids. Dans le cas d'un store, il se déroule sous l'effet du poids de sa barre de charge. D'autres configurations sont toutefois évidemment possibles.It will be noted that in what follows, it is considered that the apron 2 unrolls downwards, in particular under the effect of its own weight. In the case of a blind, it unrolls under the effect of the weight of its load bar. Other configurations are, however, obviously possible.

Une première position P1 de la barre de charge ou de l'extrémité libre du tablier 2 correspond à une position d'ouverture complète du tablier 2. A cette position correspond une position angulaire D1 du tube d'enroulement 4, comme représenté à la figure 4.A first position P1 of the load bar or of the free end of the apron 2 corresponds to a completely open position of the apron 2. To this position corresponds an angular position D1 of the winding tube 4, as shown in figure 4 .

Le long des rails de guidage disposés de part et d'autre de l'ouverture, le l'installation 1 comprend un mécanisme de blocage, représenté ici sous forme de moyens de verrouillage 18. Le mécanisme de blocage peut être logé à l'intérieur des rails de guidage et comprend notamment deux ensembles similaires de part et d'autre du tablier 2 de l'écran motorisé 1. Les moyens de verrouillage 18 coopèrent avec les extrémités de la lame inférieure 5, en particulier avec des ergots fixés élastiquement aux extrémités de la lame finale (non représentés). Ces moyens de verrouillage 18, représentés à la figure 3, déterminent, comme représenté à la figure 2, une deuxième position P2 de la lame inférieure 5, une troisième position P3 de la lame inférieure 5 et une quatrième position P4 de la lame inférieure 5. Le fonctionnement de tels moyens de verrouillage 8, connus de l'art antérieur, est notamment décrit, en référence à la figure 3, dans le deuxième mode de réalisation de la demande de brevet FR 3 009 577 . Lors d'un mouvement de descente, en rencontrant une première rampe, l'ergot est repoussé en direction de la lame inférieure 5 contre un effort élastique. Au franchissement de cette rampe, l'ergot reprend sa position de repos. Si le mouvement se poursuit, l'ergot rencontre une deuxième rampe ou rampe inférieure qui de nouveau le déplace vers la lame inférieure 5. Après avoir franchi cette rampe inférieure, l'ergot revient dans sa position de repos. La descente du tablier 2 se poursuit normalement jusqu'au seuil.Along the guide rails arranged on either side of the opening, the installation 1 comprises a locking mechanism, represented here in the form of locking means 18. The locking mechanism can be housed inside guide rails and comprises in particular two similar assemblies on either side of the apron 2 of the motorized screen 1. The locking means 18 cooperate with the ends of the lower blade 5, in particular with lugs elastically fixed to the ends of the final slat (not shown). These locking means 18, shown in picture 3 , determine, as shown in figure 2 , a second position P2 of the lower blade 5, a third position P3 of the lower blade 5 and a fourth position P4 of the lower blade 5. The operation of such locking means 8, known from the prior art, is described in particular , with reference to the picture 3 , in the second embodiment of the patent application FR 3 009 577 . During a downward movement, encountering a first ramp, the lug is pushed back in the direction of the lower blade 5 against an elastic force. On crossing this ramp, the lug resumes its rest position. If the movement continues, the lug encounters a second ramp or lower ramp which again moves it towards the lower blade 5. After having crossed this lower ramp, the lug returns to its rest position. The descent of apron 2 continues normally to the threshold.

La deuxième position P2 est une position dite verrouillée dans laquelle le tablier 2 est bloqué lors d'un mouvement de montée (ou enroulement). La deuxième position P2 correspond à une position angulaire verrouillée D2 du tube d'enroulement 4.The second position P2 is a so-called locked position in which the deck 2 is blocked during a rising movement (or winding). The second position P2 corresponds to a locked angular position D2 of the winding tube 4.

La troisième position P3 est une position d'entrée des moyens de verrouillage. Lorsque la lame inférieure 5 dépasse cette position P3 dans le sens du déroulement du tablier 2 et qu'ensuite un mouvement d'enroulement de l'écran motorisé 1 est commandé, le tablier 2 se retrouve bloqué sous la première rampe, la lame inférieure 5 se retrouvant en position P2 et le tube d'enroulement en position D2. Cette position P3 correspond à une position angulaire d'inversion D3 du tube d'enroulement 4.The third position P3 is an entry position of the locking means. When the lower slat 5 passes this position P3 in the unwinding direction of the apron 2 and then a winding movement of the motorized screen 1 is controlled, the apron 2 finds itself blocked under the first ramp, the lower slat 5 being in position P2 and the winding tube in position D2. This position P3 corresponds to an angular position of inversion D3 of the winding tube 4.

La quatrième position P4 est une position dite de sortie des moyens de verrouillage en dessous de laquelle la lame inférieure 5, ayant été verrouillée, doit venir afin que le tablier 2 puisse de nouveau être enroulé jusqu'à atteindre sa position d'ouverture totale P1. Cette position correspond à une position angulaire de sortie D4 du tube d'enroulement 4. La position P4 est une position inférieure à la position P3, cette position P3 étant inférieure à la position P2.The fourth position P4 is a so-called exit position of the locking means below which the lower slat 5, having been locked, must come so that the apron 2 can again be rolled up until it reaches its fully open position P1 . This position corresponds to an angular output position D4 of the winding tube 4. Position P4 is a position lower than position P3, this position P3 being lower than position P2.

On a représenté aux figures 3'a et 3'b deux autres installations d'écran motorisé 1 munies d'un mécanisme de blocage pouvant être réglés par l'intermédiaire du procédé de réglage selon l'invention. Ces mécanismes de blocage coopèrent avec l'extrémité libre du tablier et sont situés dans une position proche de la position de référence repérée par analyse des variations de paramètre lié au mouvement de l'écran motorisé.We represented at figures 3'a and 3'b two other motorized screen installations 1 provided with a locking mechanism which can be adjusted by means of the adjustment method according to the invention. These blocking mechanisms cooperate with the free end of the apron and are located in a position close to the reference position identified by analysis of the parameter variations linked to the movement of the motorized screen.

La Figure 3'a illustre en coupe droite une baie vitrée 20 équipée d'une installation d'écran motorisé 1. Une telle installation est notamment connue de FR2962759 . Elle comporte un tube d'enroulement 4 logé à l'intérieur d'un caisson 6 et autour duquel est apte à venir s'enrouler un tablier 2 constitué de lames 3 articulées entre elles, dont une lame inférieure 5. L'installation d'écran motorisé 1 comprend de plus deux coulisses latérales 26, 28 solidaires du caisson 6 disposées en regard l'une de l'autre, dans lesquelles les deux bordures latérales opposées 30, 32 du tablier 2 sont engagées et peuvent coulisser. Le caisson 6 est monté pivotant autour du tube d'enroulement 4 avec les coulisses latérales 26, 28. La baie 20 présente deux montants latéraux opposés 34, 36 équipés respectivement d'un vérin à gaz 38, 40 reliant les coulisses latérales 26, 28 au moyen d'une chape 42, 44. Par ce biais, les coulisses latérales 26, 28 et le tablier 2 qui s'étend entre elles, peuvent être disposés dans une position écartée des montants latéraux 34, 36. Les montants latéraux 34, 36 sont équipés respectivement d'un mécanisme de blocage constitués d'un verrou 46, 48, permettant de maintenir les coulisses latérales 26, 28 contre leur montant latéral respectif 34, 36 et donc le tablier 2 dans une position projetée, dans laquelle il est déployé dans un plan sécant au plan de son enroulement 2. La figure 3'a illustre l'écran motorisé 1 en position projetée. Cette position projetée peut être atteinte à partir du moment où l'extrémité libre 5 du tablier 2 a atteint une position de blocage P2 dans le verrou 46, 48, ici par le biais des vérins 38, 40, dans d'autres modes de réalisation par traction sur des bras. Une position P3 d'entrée dans le mécanisme de blocage constitué par le verrou 46, 48 peut également être déterminée par le procédé selon l'invention.The Figure 3'a illustrates in cross section a bay window 20 equipped with a motorized screen installation 1. Such an installation is known in particular from FR2962759 . It comprises a winding tube 4 housed inside a box 6 and around which an apron 2 consisting of slats 3 hinged together, including a lower slat 5, can be wound. motorized screen 1 further comprises two lateral slides 26, 28 integral with box 6 arranged opposite one another, in which the two opposite lateral edges 30, 32 of apron 2 are engaged and can slide. The box 6 is pivotally mounted around the winding tube 4 with the side slides 26, 28. The bay 20 has two opposite side uprights 34, 36 respectively equipped with a gas spring 38, 40 connecting the side slides 26, 28 by means of a yoke 42, 44. By this means, the side slides 26, 28 and the apron 2 which extends between them, can be arranged in a separated position of the side uprights 34, 36. The side uprights 34, 36 are respectively equipped with a locking mechanism consisting of a lock 46, 48, making it possible to hold the side slides 26, 28 against their respective side upright 34, 36 and therefore the apron 2 in a projected position, in which it is deployed in a plane secant to the plane of its winding 2. The figure 3'a illustrates the motorized screen 1 in the projected position. This projected position can be reached from the moment when the free end 5 of the apron 2 has reached a blocking position P2 in the lock 46, 48, here by means of the cylinders 38, 40, in other embodiments by arm traction. An entry position P3 in the blocking mechanism formed by the lock 46, 48 can also be determined by the method according to the invention.

La figure 3'b illustre schématiquement une installation d'écran motorisé 1, comprenant un tablier 2 muni d'une pluralité de lames orientables 3 liées entre elles. Une telle installation est notamment connue du document EP2226462 . L'extrémité libre 5 du tablier 2 comporte, sur chacune des deux extrémités, dont une seule est représentée, un ergot 50 prévu pour coopérer avec un mécanisme de basculement 52 disposé le long de la glissière 54 correspondante. Le passage de la lame inférieure 5 dans le mécanisme de basculement 52 définit, de manière similaire au mécanisme de verrouillage 18 évoqué plus haut, une position d'entrée P3 dans le mécanisme de basculement 52. Pour provoquer le basculement des lames du tablier 2, il est nécessaire que la lame finale 5 atteigne la position d'entrée P3 du mécanisme de basculement 52, lors d'un déroulement du tablier 2. Une inversion de sens vient ensuite bloquer l'ergot 50 dans une position de blocage P2. La poursuite du mouvement d'enroulement permet l'extension du tablier 2 et le basculement en ouverture des lames 3. Pour enrouler de nouveau le tablier 2, un mouvement de déroulement permet le basculement des lames 3 en fermeture, puis le déplacement de la lame inférieure 5 au-delà d'une position de sortie du mécanisme de basculement P4. Le tablier 2 peut ensuite être complètement enroulé.The figure 3'b schematically illustrates a motorized screen installation 1, comprising an apron 2 provided with a plurality of adjustable blades 3 linked together. Such an installation is known in particular from the document EP2226462 . The free end 5 of the deck 2 comprises, on each of the two ends, of which only one is shown, a lug 50 provided to cooperate with a tilting mechanism 52 arranged along the corresponding slide 54. The passage of the lower slat 5 in the tilting mechanism 52 defines, similarly to the locking mechanism 18 mentioned above, an entry position P3 in the tilting mechanism 52. To cause the tilting of the slats of the apron 2, it is necessary that the final slat 5 reaches the entry position P3 of the tilting mechanism 52, during unwinding of the apron 2. A reversal of direction then locks the lug 50 in a locking position P2. The continuation of the winding movement allows the extension of the apron 2 and the tilting in opening of the blades 3. To roll up the apron 2 again, an unwinding movement allows the tilting of the blades 3 in closing, then the displacement of the blade lower 5 beyond an exit position of the tilting mechanism P4. The apron 2 can then be completely rolled up.

On va maintenant décrire une procédure d'exécution du procédé de réglage selon l'invention en référence aux figures 4 à 7.A procedure for executing the adjustment method according to the invention will now be described with reference to the figures 4 to 7 .

De préférence, le procédé de réglage va être déclenché par l'actionnement d'un dispositif d'activation à partir d'un élément d'activation destiné à être actionné par l'utilisateur. Par exemple, le procédé de réglage va être déclenché lors de l'installation du volet roulant par exemple, par appui sur une combinaison de touches de l'interface utilisateur 8, ou par simple appui sur une touche spécifique.Preferably, the adjustment method will be triggered by the actuation of an activation device from an activation element intended to be actuated by the user. For example, the adjustment method will be triggered during the installation of the roller shutter, for example, by pressing a combination of keys of the user interface 8, or by simply pressing a specific key.

En particulier, cette combinaison de touches ou l'appui sur une touche particulière va enclencher une première étape 80 d'analyse des variations d'un paramètre lié au mouvement de l'écran motorisé 1 au cours du déplacement de l'écran motorisé 1. Dans le mode de réalisation particulier décrit ici, cette analyse est réalisée par l'actionneur.In particular, this combination of keys or the pressing of a particular key will trigger a first step 80 of analysis of the variations of a parameter linked to the movement of the motorized screen 1 during the movement of the motorized screen 1. In the particular embodiment described here, this analysis is carried out by the actuator.

Les variations du paramètre permettent notamment d'identifier des positions particulières de la lame inférieure 5 de l'écran motorisé 1. Le paramètre est de préférence le couple exercé par l'actionneur entraînant en mouvement l'écran motorisé 1 au cours d'un mouvement de montée. Ce couple est par exemple déterminé à partir d'une mesure du courant traversant un moteur électrique de l'actionneur. Dans le mode de réalisation particulier décrit ici, cette analyse est réalisée par l'actionneur, en particulier par l'unité électronique de commande 7 de l'actionneur.The variations of the parameter make it possible in particular to identify particular positions of the lower slat 5 of the motorized screen 1. The parameter is preferably the torque exerted by the actuator driving the motorized screen 1 in motion during a movement of climb. This torque is for example determined from a measurement of the current flowing through an electric motor of the actuator. In the particular embodiment described here, this analysis is carried out by the actuator, in particular by the electronic control unit 7 of the actuator.

Les variations de couple observées au cours de ce mouvement de montée (ou d'ouverture) de l'écran motorisé 1 sont représentées de manière schématique en fonction de la position angulaire du tube d'enroulement 4 à la figure 7. Ces variations correspondent aux variations du poids du tablier suspendu au tube d'enroulement 4, ainsi qu'aux variations liées au diamètre d'enroulement, ledit diamètre d'enroulement augmentant au fil de l'ouverture du fait de la superposition des enroulements de lames 2 sur le tube d'enroulement 4.The torque variations observed during this raising (or opening) movement of the motorized screen 1 are shown schematically as a function of the angular position of the winding tube 4 at the figure 7 . These variations correspond to variations in the weight of the apron suspended from the winding tube 4, as well as variations linked to the winding diameter, said winding diameter increasing over the opening due to the superposition of the blade windings 2 on the winding tube 4.

La position dans laquelle la lame inférieure 5 est décollée du seuil du volet peut être repérée de manière fiable par la détermination d'un maximum local de couple, au voisinage du mécanisme de blocage. Cette position de décollement, ou position de référence PMB, permet de déterminer la position d'entrée dans les moyens de verrouillage P3 qui sont espacées par une distance prédéterminée, qui dépend des caractéristiques du volet.The position in which the lower slat 5 is detached from the sill of the flap can be identified reliably by determining a local torque maximum, in the vicinity of the blocking mechanism. This take-off position, or reference position PMB, makes it possible to determine the entry position into the locking means P3 which are spaced apart by a predetermined distance, which depends on the characteristics of the flap.

Ainsi, au cours d'une deuxième étape 90 qui sera déclenchée après l'étape 80, on détermine, à partir de l'analyse réalisée à l'étape précédente, la position de référence PMB par détection d'une valeur maximum locale du paramètre ou d'une valeur de variation maximum locale du paramètre. Dans le mode de réalisation particulier décrit ici, cette détermination est réalisée par l'actionneur et par comparaison à un seuil de couple.Thus, during a second step 90 which will be triggered after step 80, the reference position PMB is determined from the analysis carried out in the previous step by detecting a local maximum value of the parameter or a local maximum variation value of the parameter. In the particular embodiment described here, this determination is made by the actuator and by comparison with a torque threshold.

Puis, au cours d'une étape 100, on détermine la position d'entrée dans les moyens de verrouillage P3. Plus particulièrement, la position d'entrée dans les moyens de verrouillage P3 est obtenue par décalage d'une valeur prédéterminée à partir de la position de référence PMB. Ce décalage prend notamment en compte la géométrie et/ou les dimensions du mécanisme de blocage, ainsi que la position préférentielle de montage de celui-ci dans l'installation, notamment au bas des rails de guidage. En particulier, la position angulaire D3 associée à la position P3 est liée à la position angulaire DMB associée à la position de décollement par la relation suivante : D3 = DMB+360°.Then, during a step 100, the entry position in the locking means P3 is determined. More particularly, the entry position in the locking means P3 is obtained by shifting a predetermined value from the reference position PMB. This offset notably takes into account the geometry and/or the dimensions of the locking mechanism, as well as the preferred mounting position of the latter in the installation, in particular at the bottom of the guide rails. In particular, the angular position D3 associated with the position P3 is linked to the angular position DMB associated with the separation position by the following relationship: D3=DMB+360°.

La détermination de la position de référence PMB se fait notamment lors d'un mouvement de montée ou d'enroulement du tablier. Le procédé de réglage peut cependant être poursuivi, notamment pour affiner cette position d'entrée P3 dans le mécanisme de blocage. Ainsi, d'autres mouvements sont ensuite mis en œuvre par l'actionneur, notamment un mouvement de descente ou de déroulement, conduisant la lame inférieure 5 dans la position P3 lors d'un mouvement de déroulement. La lame inférieure 5 se trouve alors dans les moyens de verrouillage et dans une zone dite d'inversion de sens. Dans cette zone d'inversion de sens, une inversion du sens de déplacement de la lame inférieure 5, d'un mouvement de descente à un mouvement de montée, provoque un blocage de la lame inférieure 5 dans les moyens de verrouillage 18. Hors de cette zone, l'inversion de sens de déplacement de la lame inférieure 5 ne produit pas d'effet particulier. La lame inférieure 5 peut notamment traverser les moyens de verrouillage 18 dans le sens de la descente comme dans le sens de la montée sans être verrouillée s'il ne se produit pas d'inversion de son sens de déplacement entre les positions P3 et P4.The determination of the reference position PMB is done in particular during a rising or winding movement of the apron. The adjustment process can however be continued, in particular to refine this entry position P3 in the blocking mechanism. Thus, other movements are then implemented by the actuator, in particular a downward or unwinding movement, leading the lower slat 5 into position P3 during an unwinding movement. The lower blade 5 is then in the locking means and in a so-called direction reversal zone. In this direction inversion zone, a reversal of the direction of movement of the lower slat 5, from a downward movement to an upward movement, causes the lower slat 5 to become blocked in the locking means 18. this zone, reversing the direction of movement of the lower blade 5 does not produce any particular effect. The lower blade 5 can in particular pass through the locking means 18 in the downward direction as well as in the upward direction without being locked if there is no reversal of its direction of movement between the positions P3 and P4.

La position P3 déterminée au terme de l'étape de détermination 100 est choisie comme première position d'inversion de rotation candidate PM1. Elle correspond à une position angulaire DM1.The position P3 determined at the end of the determination step 100 is chosen as the first candidate rotation inversion position PM1. It corresponds to an angular position DM1.

Durant une étape 102, la position P3 est enregistrée dans la mémoire 16 de l'unité électronique de commande 7. Puis, la lame inférieure 5 est déplacée, dans le sens du déroulement, jusqu'à cette position P3 ainsi enregistrée.During a step 102, the position P3 is recorded in the memory 16 of the electronic control unit 7. Then, the lower slat 5 is moved, in the direction of unwinding, to this position P3 thus recorded.

Par la suite, au cours d'une étape 104 déclenchée de préférence automatiquement, le tablier 2 est ensuite entraîné dans le sens de l'enroulement jusqu'à la position verrouillée P2. A cet effet, une alimentation du motoréducteur est commandée provoquant l'enroulement du tablier 2 et par conséquent la montée de la lame inférieure 5. Dans une variante, l'étape 104 pourrait également faire suite à une action de l'installateur.Subsequently, during a step 104 preferably triggered automatically, the apron 2 is then driven in the winding direction to the locked position P2. To this end, a power supply to the gear motor is controlled causing the winding of the apron 2 and consequently the raising of the lower slat 5. Alternatively, step 104 could also follow an action by the installer.

Une fois la lame inférieure 5 bloquée dans les moyens de verrouillage 18, au cours d'une étape 106, la deuxième position P2 est détectée par le capteur de couple 12, par exemple par détection d'un surcouple, et l'alimentation du motoréducteur est coupée. La valeur de position angulaire D2 du tube d'enroulement 4 correspondant à la position P2 de la lame inférieure est alors enregistrée en mémoire dans l'unité de commande 7. On notera que la valeur de P2 enregistrée peut correspondre à une position légèrement inférieure à la position de blocage de la lame inférieure 5, de manière à ce qu'une fois dans le mode d'utilisation, lorsqu'un utilisateur commande le verrouillage du tablier 2, la lame inférieure 5 ne vienne pas en butée en exerçant des efforts importants sur les moyens de verrouillage 18.Once the lower blade 5 is blocked in the locking means 18, during a step 106, the second position P2 is detected by the torque sensor 12, for example by detecting an overtorque, and the power supply to the gear motor is cut. The angular position value D2 of the winding tube 4 corresponding to the position P2 of the lower slat is then stored in memory in the control unit 7. It will be noted that the value of P2 stored may correspond to a position slightly lower than the locking position of the lower slat 5, so that once in the mode of use, when a user controls the locking of the apron 2, the lower slat 5 does not come into abutment by exerting significant forces on the locking means 18.

Après enregistrement de la position P2, une séquence itérative est initiée. Cette séquence comprend au moins deux étapes a) et b).After recording the position P2, an iterative sequence is initiated. This sequence comprises at least two steps a) and b).

Au cours de l'étape a), ou 108 telle que représentée sur le schéma de la figure 5, le tablier 2 est entraîné dans le sens du déroulement jusqu'à une deuxième position d'inversion de rotation candidate PM2 située au-delà de la première position d'inversion de rotation PM1 dans le sens du déroulement du tablier 2. Au cours de cette étape peut également être enregistrée la distance ou le temps de déplacement entre les positions PM1 et P2.During step a), or 108 as shown in the diagram of figure 5 , the apron 2 is driven in the unwinding direction to a second candidate rotation reversal position PM2 situated beyond the first rotation reversal position PM1 in the unwinding direction of the apron 2. During this step can also be recorded the distance or travel time between positions PM1 and P2.

De préférence, la deuxième position d'inversion de rotation candidate est située à une distance prédéterminée d de la première position d'inversion de rotation candidate. Ainsi, comme illustré à la figure 3, la deuxième position d'inversion de rotation PM2 est située à une distance d prédéterminée de la première position d'inversion de rotation candidate PM1. En pratique, l'installation d'écran motorisé 1 commande le déroulement du tablier 2 selon une rotation permettant à la lame inférieure 5 d'atteindre, depuis la position de verrouillage P2, la position PM1-d dans le sens du déroulement. La distance d est choisie avantageusement en fonction de dimensions générales standards des moyens de verrouillage. De manière générale, chaque position d'inversion de rotation candidate d'une nouvelle itération de la séquence est située à une distance prédéterminée d de la précédente position d'inversion de rotation candidate.Preferably, the second candidate rotation reversal position is located at a predetermined distance d from the first candidate rotation reversal position. Thus, as illustrated in picture 3 , the second rotation reversal position PM2 is located at a predetermined distance d from the first candidate rotation reversal position PM1. In practice, the motorized screen installation 1 controls the unwinding of the apron 2 according to a rotation allowing the lower slat 5 to reach, from the locking position P2, the position PM1-d in the unwinding direction. The distance d is advantageously chosen according to standard general dimensions of the locking means. In general, each candidate rotation reversal position of a new iteration of the sequence is located at a predetermined distance d from the previous candidate rotation reversal position.

La position d'inversion de rotation candidate PM2 définie par l'unité électronique de commande 7 est mise en mémoire 16 de l'unité de commande 7.The candidate rotation reversal position PM2 defined by the electronic control unit 7 is stored in memory 16 of the control unit 7.

Puis, au cours de l'étape b), ou 110 telle que représentée sur le schéma de la figure 5, le tablier 2 est à nouveau entraîné dans le sens de l'enroulement jusqu'à la position verrouillée P2. La position d'inversion de rotation candidate PM2 peut alors être associée à la distance ou au temps de déplacement entre les positions PM2 et P2.Then, during step b), or 110 as shown in the diagram of figure 5 , the apron 2 is again driven in the winding direction to the locked position P2. The candidate rotation reversal position PM2 can then be associated with the distance or the travel time between the positions PM2 and P2.

La séquence a), b) est ensuite répétée jusqu'à ce que l'extrémité libre du tablier 2, à savoir la lame inférieure 5 du tablier 2, dépasse la position de sortie P4, au-delà de laquelle le verrouillage de l'écran motorisé 1 n'est plus activé lorsque l'écran motorisé 1 est entraîné dans le sens de l'enroulement.The sequence a), b) is then repeated until the free end of the apron 2, namely the lower slat 5 of the apron 2, passes the exit position P4, beyond which the locking of the motorized screen 1 is no longer activated when motorized screen 1 is driven in the winding direction.

Dans l'exemple d'application du mode de réalisation du procédé illustré à la figure 3, le tablier 2 est entraîné dans le sens du déroulement jusqu'à une troisième position d'inversion de rotation candidate PM3 située au-delà de première position d'inversion de rotation PM1 dans le sens du déroulement du tablier 2. La troisième position d'inversion de rotation candidate PM3 est située à une distance d de la précédente position d'inversion candidate PM2, c'est-à-dire à une distance 2d de la première position d'inversion candidate PM1.In the example of application of the embodiment of the method illustrated in picture 3 , the apron 2 is driven in the unwinding direction to a third candidate rotation reversal position PM3 located beyond the first rotation reversal position PM1 in the unwinding direction of the apron 2. The third position d candidate rotation inversion PM3 is located at a distance d from the previous candidate reversal position PM2, that is to say at a distance 2d from the first candidate reversal position PM1.

La position PM3 est alors enregistrée dans la mémoire 16 de l'unité de commande 7 et l'étape b) se reproduit également : l'enroulement du tablier 2 est effectuée jusqu'à ce que la lame inférieure 5 se retrouve dans la position P2.The position PM3 is then recorded in the memory 16 of the control unit 7 and step b) is also reproduced: the winding of the apron 2 is carried out until the lower blade 5 finds itself in the position P2 .

Puis, dans l'exemple illustré à la figure 3, la lame inférieure 5 est déplacée jusqu'à une quatrième position PM4 équivalente à PM3-d. En l'occurrence, cette position, se trouve au-delà de la position de sortie P4. De ce fait, lors de la remontée du tablier 2, aucun obstacle n'est plus détecté au niveau de P2 car le tablier 2 devient libre de remonter vers la position P1 sans être stoppé par les moyens de verrouillage 18. Au cours de l'étape 112, cette absence de détection d'obstacle au-delà de P2 dans le sens de l'enroulement permet de décider l'interruption de l'itération de la séquence a)-b). Cette quatrième position PM4 n'est donc pas considérée comme une position d'inversion de rotation candidate. Puis, au cours d'une étape 114, l'enroulement de l'écran motorisé 1 se poursuit et la lame inférieure 5 remonte jusqu'à la position P1.Then, in the example shown in picture 3 , the lower blade 5 is moved to a fourth position PM4 equivalent to PM3-d. In this case, this position is beyond the output position P4. As a result, when the apron 2 is raised, no obstacle is detected at the level of P2 because the apron 2 becomes free to go up towards the position P1 without being stopped by the locking means 18. During the step 112, this absence of obstacle detection beyond P2 in the winding direction makes it possible to decide to interrupt the iteration of the sequence a)-b). This fourth position PM4 is therefore not considered as a candidate rotation reversal position. Then, during a step 114, the winding of the motorized screen 1 continues and the lower slat 5 rises to position P1.

Tant qu'un obstacle est détecté au niveau de P2 lors de la remontée du tablier 2 lors de l'étape b) (étape 110), l'itération de la séquence a)-b) se poursuit. Dans une variante, ou en complément de l'étape 112, la décision de l'interruption de la séquence a)-b) peut être prise après que se soit écoulée une durée prédéterminée à partir du démarrage de l'enroulement.As long as an obstacle is detected at the level of P2 during the ascent of the apron 2 during step b) (step 110), the iteration of the sequence a)-b) continues. Alternatively, or in addition to step 112, the decision to interrupt the sequence a)-b) can be taken after a predetermined time has elapsed from the start of the winding.

L'interruption de l'itération séquence a)-b) après une ou plusieurs itération permet de valider la configuration du dispositif. La valeur de position angulaire D4 du tube d'enroulement correspondant à la position P4 est alors automatiquement définie à partir de la dernière position d'inversion de rotation, dans l'exemple ci-dessus la position PM4 avant l'interruption de la séquence a)-b).The interruption of the iteration sequence a)-b) after one or more iterations makes it possible to validate the configuration of the device. The angular position value D4 of the winding tube corresponding to the position P4 is then automatically defined from the last rotation reversal position, in the example above the position PM4 before the interruption of the sequence a )-b).

Grâce à l'enregistrement des différentes positions d'inversion de rotations candidates PM1, PM2, PM3, notamment associées aux distances entre ces positions et la position P2, on peut choisir parmi celles-ci la position la plus adéquate ou optimale, à savoir n'étant ni trop proche de P2, ni trop proche de P4. Il peut par exemple s'agir dans l'exemple représenté sur les figures de PM2. On peut également sélectionner une position d'inversion de rotation optimale comme étant une position intermédiaire entre deux positions candidates préalablement enregistrées. Alternativement, la dernière position d'inversion de rotation candidate peut être sélectionnée comme position d'inversion de rotation optimale.Thanks to the recording of the various positions of inversion of candidate rotations PM1, PM2, PM3, in particular associated with the distances between these positions and the position P2, it is possible to choose from among these the most suitable or optimal position, namely n being neither too close to P2 nor too close to P4. It can for example be in the example shown in the figures of PM2. It is also possible to select an optimal rotation reversal position as being an intermediate position between two previously recorded candidate positions. Alternatively, the last candidate rotation reversal position can be selected as the optimal rotation reversal position.

La valeur de la position optimale retenue est utilisée dans le mode d'utilisation de l'installation d'écran motorisé 1. En effet, lorsque l'utilisateur envoie à l'installation d'écran motorisé 1, en position ouverture, un ordre de positionnement en ventilation sécurisée, l'installation d'écran motorisé 1 exécute tout d'abord une action de rotation du tube d'enroulement 4 dans le sens du déroulement du tablier 2. Puis, lorsque le capteur de position 10 détecte que le tube d'enroulement 4 a atteint la position optimale correspondant au fait que la lame inférieure 5 se trouve en position optimale, l'installation d'écran motorisé 1 exécute une action d'arrêt du mouvement de rotation du tube d'enroulement 4. L'installation d'écran motorisé 1 exécute alors immédiatement une action de rotation du tube d'enroulement 4 dans le sens de l'enroulement jusqu'à ce que la position D2 soit atteinte, signifiant que la lame inférieure 5 se trouve verrouillée en position P2 et donc que le tablier a atteint la position de ventilation sécurisée demandée.The value of the optimal position retained is used in the mode of use of the motorized screen installation 1. Indeed, when the user sends to the motorized screen installation 1, in the open position, an order to positioning in secure ventilation, the motorized screen installation 1 first performs a rotation action of the winding tube 4 in the direction of the unwinding of the apron 2. Then, when the position sensor 10 detects that the tube winding 4 has reached the optimum position corresponding to the fact that the lower slat 5 is in the optimum position, the motorized screen installation 1 performs an action of stopping the rotational movement of the winding tube 4. The installation motorized screen 1 then immediately executes an action of rotation of the winding tube 4 in the winding direction until position D2 is reached, meaning that the lower slat 5 is locked in position P2 and therefore that the apron reached nt the requested safe ventilation position.

Naturellement, les exemples représentés sur les figures et discutés ci-dessus ne sont donnés qu'à titre illustratif et non limitatif. Diverses variantes sont envisageables. En particulier, la description donnée à titre d'exemple de moyens de verrouillage est tout à fait applicable également à d'autres types de mécanismes de blocage fonctionnant de manière similaire. Les sens de déplacement pour atteindre ou quitter la position de blocage peuvent être adaptés en fonction des types de mécanismes de blocage.Naturally, the examples represented in the figures and discussed above are given only by way of illustration and not limitation. Various variants are possible. In particular, the description given by way of example of locking means is entirely applicable also to other types of locking mechanisms operating in a similar manner. The directions of movement to reach or leave the blocking position can be adapted according to the types of blocking mechanisms.
