Description

La présente invention concerne le domaine des protections solaires motorisées, et en particulier des stores à bras, comme par exemple les stores de terrasse, et plus particulièrement un procédé comme défini dans le préambule de la revendication 1. Un tel procédé est connu du document FR 2 816 465 .The present invention relates to the field of motorized sunshades, and in particular to armored blinds, such as terrace awnings, and more particularly to a method as defined in the preamble of claim 1. Such a method is known from the document FR 2 816 465 .

Des installations existantes de stores motorisées comprennent une toile de store et des bras dépliables de guidage de la toile dont le mouvement accompagne un mouvement de déploiement ou de repli de la toile, la toile étant susceptible de s'enrouler autour d'un tube mis en mouvement par un actionneur.Existing installations for motorized blinds comprise a blind fabric and foldable arms for guiding the fabric, the movement of which accompanies a movement of deployment or folding of the fabric, the fabric being capable of wrapping around a tube placed in movement by an actuator.

Plus précisément, une installation de store à bras comprend généralement les éléments suivants : un tube d'enroulement, maintenu à ses extrémités dans un coffre ou par des supports, des bras dépliables, une toile de store et une barre rigide dite barre de charge. Un actionneur tubulaire permet de motoriser l'installation.Specifically, a blind installation generally includes the following elements: a winding tube, held at its ends in a trunk or by supports, foldable arms, a blind fabric and a rigid bar said load bar. A tubular actuator makes it possible to motorize the installation.

La toile de store est fixée par un de ses côtés sur le tube d'enroulement à l'intérieur duquel se trouve l'actionneur tubulaire. Cet actionneur entraîne en rotation le tube et par conséquent permet d'enrouler ou de dérouler la toile. La toile est également fixée sur son côté opposé, à ladite barre de charge. Celle-ci permet de maintenir la toile et, éventuellement, sert à refermer le coffre du store lorsque la toile est dans sa position repliée.The blind fabric is fixed by one of its sides on the winding tube inside which is the tubular actuator. This actuator rotates the tube and therefore allows to roll or unroll the canvas. The fabric is also fixed on its opposite side to said load bar. This allows to maintain the fabric and possibly serves to close the chest of the awning when the fabric is in its folded position.

Les bras du store sont fixés d'une part au coffre du store (ou à des supports appropriés) et d'autre part à la barre de charge. Ils présentent au moins un coude articulé, leur permettant de se plier ou de se déplier. Les bras sont munis, généralement au niveau du coude, de ressorts bandés lors du repli de la toile.The awning arms are fixed on the one hand to the awning box (or to appropriate supports) and on the other hand to the load bar. They have at least one articulated elbow, allowing them to bend or unfold. The arms are provided, generally at the elbow, with springs bandaged during the folding of the fabric.

Les stores à bras se déploient généralement de façon sensiblement horizontale. Le déploiement de la toile ne peut donc pas être réalisé uniquement sous l'effet du poids de la barre de charge. Pour le déploiement, les bras ont tendance, sous l'effet des ressorts, à chercher à se déplier. De ce fait, si l'actionneur libère la rotation du tube d'enroulement, la toile est entraînée par les bras et le store se déploie.Arm awnings are generally deployed in a substantially horizontal manner. The deployment of the canvas therefore can not be achieved solely under the effect of the weight of the load bar. For deployment, the arms tend, under the effect of the springs, to seek to unfold. Therefore, if the actuator releases the rotation of the winding tube, the fabric is driven by the arms and the blind unfolds.

Lors du repli du store, l'actionneur entraîne le tube d'enroulement en rotation, ce qui a pour effet de tirer sur les bras par l'intermédiaire de la toile pour les replier.When folding the awning, the actuator drives the winding tube in rotation, which has the effect of pulling the arms through the fabric to fold them.

Les ressorts des bras ont en général un fort coefficient de raideur. En effet, il est requis que les stores classiquement vendus sur le marché soient déroulés avec la toile fortement tendue, quelle que soit la position d'arrêt, ceci pour des raisons esthétiques et techniques (absence de poche d'eau en cas de pluie, maintien plus rigide et donc résistance au vent, etc.).The springs of the arms generally have a high coefficient of stiffness. Indeed, it is required that the blinds classically sold on the market are unrolled with the canvas tight, regardless of the stopping position, this for aesthetic and technical reasons (no water bag in case of rain, maintaining more rigid and therefore wind resistance, etc.).

Ces contraintes en tension de la toile provoquent dans le temps une distension et un allongement de celle-ci qui peut conduire à effectuer des re-réglages.These stresses in tension of the fabric cause in time a distension and an elongation thereof which may lead to re-adjustments.

La position complètement déployée, également connue sous les termes de « position de fin de course basse » est repérée sans butée, généralement grâce à un dispositif de comptage. Dans les installations existantes, cette position correspond également à une position de verrouillage dans laquelle les bras sont dépliés au-delà d'une position où des segments du bras sont alignés. Plus précisément, dans les installations existantes, chaque bras comporte au moins deux segments articulés l'un par rapport à l'autre autour d'un axe de rotation perpendiculaire au plan de déplacement. Un angle α est défini par les deux segments dans le plan de déplacement. Cet angle α va croissant au fur et à mesure que la toile est déployée. La position de verrouillage correspond à une position dans laquelle l'angle α est supérieur à 180°. Dans cette position, on dit que les bras sont « arc-boutés ». Cette position de verrouillage permet un bon maintien de la tension de la toile, notamment par rapport au vent.The fully deployed position, also known as the "low end position" is marked without a stop, usually by means of a counting device. In existing installations, this position also corresponds to a locking position in which the arms are unfolded beyond a position where segments of the arm are aligned. More specifically, in existing installations, each arm has at least two segments articulated with respect to each other about an axis of rotation perpendicular to the plane of displacement. An angle α is defined by the two segments in the plane of displacement. This angle α increases as the fabric is deployed. The locking position corresponds to a position in which the angle α is greater than 180 °. In this position, we say that the arms are "arched". This locking position allows a good maintenance of the tension of the fabric, especially with respect to the wind.

En revanche, le passage de cette position de verrouillage, lors du déploiement ou plus particulièrement du repli de la toile, nécessite que l'actionneur soit capable de développer un fort couple d'entraînement.However, the passage of this locking position, during deployment or more particularly the folding of the fabric, requires that the actuator is able to develop a strong driving torque.

De ce fait, les actionneurs destinés aux stores à bras sont dimensionnés pour un fort couple, qui n'est globalement nécessaire que pour le déverrouillage des bras, c'est-à-dire le passage de la position verrouillée. Le reste de la course ne nécessite qu'un couple moyen.Therefore, the actuators for arm awnings are dimensioned for a high torque, which is generally necessary only for the unlocking of the arms, that is to say the passage of the locked position. The rest of the race requires only an average couple.

De plus, l'ensemble du store doit répondre à des critères de précision, de sensibilité et d'étanchéité.In addition, the entire blind must meet criteria of accuracy, sensitivity and tightness.

Compte-tenu de ces critères, la motorisation des stores est coûteuse puisque les actionneurs doivent être puissants (de 25 à 120 Nm) et les dispositifs de comptage élaborés.Given these criteria, the motorization of the blinds is expensive since the actuators must be powerful (from 25 to 120 Nm) and metering devices developed.

L'invention cherche donc à contourner ces exigences et se propose de simplifier la commande de l'installation de store, tout en conservant une tension de toile adaptée à la demande du marché.The invention therefore seeks to circumvent these requirements and proposes to simplify the control of the blind installation, while maintaining a canvas tension adapted to the market demand.

Elle a donc pour objet un procédé de commande d'une installation de store comme défini dans la revendication 1.It therefore relates to a control method of a blind installation as defined in claim 1.

Le fait de déclencher l'étape d'enroulement de la toile dès que la tension de la toile chute, permet notamment de retendre automatiquement cette toile. De plus, utiliser une grandeur représentative de la tension de la toile simplifie le procédé de commande puisqu'il n'est plus nécessaire de recourir à des dispositifs de comptage pour commander l'arrêt du déploiement de la toile. En fait une simple butée propre à arrêter le dépliement des bras suffit à provoquer une chute de la tension de la toile et donc à arrêter son déploiement.The triggering of the step of winding the fabric as soon as the tension of the fabric drops, allows in particular to automatically retension this fabric. Moreover, using a magnitude representative of the tension of the fabric simplifies the control method since it is no longer necessary to resort to counting devices to control the stopping of the deployment of the fabric. In fact a simple stop to stop the unfolding of the arms is enough to cause a drop in the tension of the fabric and therefore stop its deployment.

Enfin, détecter une chute de la tension de la toile à partir de la grandeur représentative de cette tension permet non seulement de retendre la toile lorsque les bras sont arrivés en butée, mais également de retendre la toile lorsque les bras ont rencontré un obstacle extérieur à l'installation du store.Finally, detecting a drop in the tension of the fabric from the magnitude representative of this tension not only allows the canvas to be tightened when the arms have reached an abutment, but also to tighten the fabric when the arms have encountered an external obstacle to the installation of the awning.

Par l'expression « un repli perceptible des bras », on définit ici un mouvement de repli des bras correspondant à un déplacement de la toile inférieur à 5% de la course totale de cette toile entre une position complètement repliée et une position complètement déployée.By the expression "a perceptible retraction of the arms", here is defined a folding movement of the arms corresponding to a displacement of the web less than 5% of the total stroke of this fabric between a fully folded position and a fully deployed position.

Les modes de réalisation de ce procédé peuvent comporter une ou plusieurs des caractéristiques suivantes :

  • l'étape de surveillance comprend une mesure du couple exercé par l'actionneur sur le tube d'enroulement ;
  • l'étape d'enroulement est automatiquement arrêtée dès que la grandeur représentative de la tension de la toile devient supérieure à un seuil prédéterminé ou dès que la variation de la grandeur représentative dépasse un seuil prédéterminé ;
  • l'étape d'enroulement est automatiquement arrêtée dès qu'une durée prédéterminée est écoulée depuis le déclenchement de l'étape d'enroulement ;
  • la durée ou le seuil est prédéterminé lors d'une phase d'apprentissage pour ne pas provoquer de repli perceptible des bras.
Embodiments of this method may include one or more of the following features:
  • the monitoring step comprises measuring the torque exerted by the actuator on the winding tube;
  • the winding step is automatically stopped as soon as the magnitude representative of the tension of the fabric becomes greater than a predetermined threshold or as soon as the variation of the representative quantity exceeds a predetermined threshold;
  • the winding step is automatically stopped as soon as a predetermined time has elapsed since the initiation of the winding step;
  • the duration or the threshold is predetermined during a learning phase so as not to provoke perceptible fold of the arms.

Ces modes de réalisation du procédé présentent en outre les avantages suivants :

  • utiliser une mesure du couple de l'actionneur en tant que grandeur représentative de la tension de la toile permet de loger le capteur dans le tube d'enroulement ou même dans l'actionneur et donc de le protéger,
  • arrêter l'étape d'enroulement en fonction d'un seuil prédéterminé de tension permet de garantir que la toile a été retendue,
  • arrêter l'étape d'enroulement après une durée prédéterminée permet de retendre la toile sans pour cela mesurer à nouveau la tension de cette toile, et
  • déterminer la durée prédéterminée ou le seuil prédéterminé pour ne pas provoquer de repliement perceptible des bras permet de maintenir un déploiement maximal de cette toile.
These embodiments of the method furthermore have the following advantages:
  • using a measurement of the torque of the actuator as a magnitude representative of the voltage of the fabric makes it possible to house the sensor in the winding tube or even in the actuator and thus to protect it,
  • stopping the winding step as a function of a predetermined threshold of tension makes it possible to guarantee that the fabric has been stretched,
  • stopping the winding step after a predetermined time makes it possible to tighten the fabric without again measuring the tension of this fabric, and
  • determining the predetermined duration or the predetermined threshold so as not to cause perceptible folding of the arms makes it possible to maintain maximum deployment of this fabric.

L'invention a également pour objet une installation de stores motorisée comprenant :

  • une toile de store,
  • un actionneur commandable propre à entraîner l'enroulement de la toile du store sur un tube d'enroulement,
  • plusieurs bras dépliables susceptibles d'accompagner le mouvement de la toile du store,
  • un capteur propre à mesurer une grandeur représentative de la tension de la toile pendant son déploiement, et
  • un calculateur apte à commander l'actionneur, et apte à mettre en oeuvre le procédé de commande ci-dessus.
The invention also relates to a motorized blind installation comprising:
  • a shade cloth,
  • a controllable actuator capable of driving the winding of the fabric of the blind onto a winding tube,
  • several foldable arms that may accompany the movement of the awning fabric,
  • a sensor capable of measuring a magnitude representative of the tension of the fabric during its deployment, and
  • a computer adapted to control the actuator, and adapted to implement the control method above.

Les modes de réalisation de cette installation peuvent comporter les caractéristiques suivantes :

  • chaque bras comporte au moins deux segments pouvant pivoter l'un par rapport à l'autre dans un plan de déplacement des bras, un angle α défini par les deux segments dans le plan de déplacement allant croissant au fur et à mesure que la toile est déployée, l'installation comportant un mécanisme de butée propre à provoquer un blocage des bras lors de leur dépliement lorsque la valeur de l'angle α atteint une valeur donnée dite angle de blocage, inférieure à 180° et de préférence inférieure à 150° ;
  • l'installation comprend un mécanisme de retenue permettant le maintien de l'angle α dans une plage de +/X° autour de l'angle de blocage tant qu'un effort de traction exercé sur les bras pour réduire cet angle reste en deçà d'un seuil prédéfini de traction, X étant petit devant la valeur de l'angle de blocage, et de préférence inférieur à 5° ;
  • le mécanisme de butée et/ou de retenue est ajustable de manière à régler la valeur de l'angle de blocage, le seuil prédéfini de traction ou la valeur de X.
Embodiments of this installation may include the following features:
  • each arm has at least two segments pivotable relative to each other in a plane of movement of the arms, an angle α defined by the two segments in the plane of movement increasing as the fabric is deployed, the installation comprising a stop mechanism capable of causing a blocking of the arms during their unfolding when the value of the angle α reaches a given value called blocking angle, less than 180 ° and preferably less than 150 °;
  • the installation comprises a retaining mechanism enabling the angle α to be maintained in a range of + / X ° around the locking angle as long as a tensile force exerted on the arms to reduce this angle remains below a predetermined threshold of traction, X being small in front of the value of the blocking angle, and preferably less than 5 °;
  • the stop and / or retaining mechanism is adjustable so as to adjust the value of the locking angle, the predefined threshold of traction or the value of X.

Ces modes de réalisation de l'installation présentent en outre les avantages suivants :

  • maintenir l'angle α en dessous de 180°, permet d'utiliser un actionneur moins puissant pour enrouler la toile, ce qui simplifie la conception de l'installation de store, et
  • utiliser un mécanisme de retenue pour maintenir l'angle α si un effort, inférieur à un seuil prédéfini, est appliqué pour réduire cet angle, permet de verrouiller la toile à proximité de sa position complètement déployée sans utiliser d'énergie électrique.
These embodiments of the installation also have the following advantages:
  • maintain the angle α below 180 °, allows the use of a less powerful actuator to wind the fabric, which simplifies the design of the awning installation, and
  • using a retaining mechanism to maintain the angle α if a force, below a predefined threshold, is applied to reduce this angle, makes it possible to lock the fabric near its fully deployed position without using electrical energy.

The invention will be better understood on reading the description which follows, given solely by way of nonlimiting example and with reference to the drawings in which:
  • Figure la is a schematic perspective illustration of a blind installation,
  • the Figures 2a, 2b and 2c schematically represent the installation of the figure 1 in three different positions,

La figure 1 présente une installation 1 de store à bras selon l'invention.The figure 1 presents a blind arm installation 1 according to the invention.

A l'intérieur d'un coffre 2 fixé sur une structure, par exemple une façade d'un bâtiment, se trouve un tube d'enroulement 21 sur lequel s'enroule une toile de store 3. L'installation comprend également deux bras pliables 4, fixés d'un côté directement au coffre 2 et de l'autre côté sur une barre de charge 5 maintenant la toile 3 tendue dans le sens de la largeur.Inside a box 2 fixed to a structure, for example a facade of a building, is a winding tube 21 on which wraps a blind fabric 3. The installation also includes two folding arms 4, fixed on one side directly to the chest 2 and the other side on a load bar 5 holding the fabric 3 stretched in the width direction.

Les bras 4 se plient et se déplient dans un plan commun de déplacement. Par exemple, ici, le plan de déplacement est sensiblement parallèle au plan de la toile 3. Chaque bras est formé de deux segments 41 et 42. Une extrémité du segment 41 est reliée à une autre extrémité du segment 42 par l'intermédiaire d'une charnière 43 formant un coude articulé. La charnière 43 permet un pivotement des segments 41 et 42 l'un par rapport à l'autre autour d'un axe de rotation perpendiculaire au plan de déplacement. L'angle défini entre les segments 41 et 42 dans le plan de déplacement est noté ici α.The arms 4 fold and unfold in a common plane of movement. For example, here, the plane of displacement is substantially parallel to the plane of the web 3. Each arm is formed of two segments 41 and 42. One end of the segment 41 is connected to another end of the segment 42 via a hinge 43 forming an articulated elbow. The hinge 43 allows pivoting of the segments 41 and 42 relative to each other about an axis of rotation perpendicular to the plane of movement. The angle defined between the segments 41 and 42 in the plane of displacement is noted here α.

Chaque bras est équipé d'un dispositif élastique 10 propre à solliciter le bras vers une position dépliée. Généralement, le dispositif 10 se présente sous la forme de ressorts bandés lors du pliage des bras 4.Each arm is equipped with an elastic device 10 capable of biasing the arm towards an unfolded position. Generally, the device 10 is in the form of springs bandaged during the folding of the arms 4.

Chaque bras comprend également un mécanisme 11 de butée réglable. Ce mécanisme 11 permet d'imposer une valeur maximale αmax pour l'angle α. La valeur αmax est toujours strictement inférieure à 180° et de préférence inférieure à 150°. Des exemples de modes de réalisation du mécanisme 11 sont décrits en regard des figures 6a et 6b.Each arm also comprises an adjustable stop mechanism 11. This mechanism 11 makes it possible to impose a maximum value α max for the angle α. The value α max is always strictly less than 180 ° and preferably less than 150 °. Examples of embodiments of the mechanism 11 are described with reference to the Figures 6a and 6b .

Le dispositif d'actionnement est maintenant décrit en regard de la figure 1b.The actuating device is now described with regard to the figure 1b .

Dans le tube d'enroulement se trouve un actionneur tubulaire 6, muni d'un axe de sortie sous forme d'une roue entraînant le tube 21 en rotation dans un premier sens et, en alternance, dans un deuxième sens opposé. Par exemple, l'axe de sortie est fixé à l'axe du tube 21 sans aucun degré de liberté. L'actionneur 6 comporte une partie d'entraînement ou moto-réducteur 6a ainsi qu'un frein 6b. Le frein permet de contrôler la vitesse de rotation et également de maintenir bloqué le tube d'enroulement.In the winding tube is a tubular actuator 6, provided with an output shaft in the form of a wheel driving the tube 21 in rotation in a first direction and, alternately, in a second opposite direction. For example, the output axis is fixed to the axis of the tube 21 without any degree of freedom. The actuator 6 comprises a driving portion or geared motor 6a and a brake 6b. The brake makes it possible to control the speed of rotation and also to keep the winding tube blocked.

Lors du déploiement de la toile, l'actionneur 6 libère au moins partiellement le frein 6b et donc la rotation du tube d'enroulement dans le premier sens, sous l'action du dispositif élastique 10. La barre de charge 5 et la toile 3 sont alors entraînés vers la position complètement déployée.During the deployment of the fabric, the actuator 6 at least partially releases the brake 6b and therefore the rotation of the winding tube in the first direction, under the action of the elastic device 10. The load bar 5 and the fabric 3 are then driven to the fully deployed position.

L'actionneur comprend également un capteur 7 de couple d'entraînement de la toile. Ce capteur 7 permet de mesurer une grandeur représentative de la tension de la toile 3. Alternativement, ce sont les variations de cette grandeur représentative qui permettent de déclencher les actions de déploiement ou de repli.The actuator also comprises a webbing torque sensor 7. This sensor 7 makes it possible to measure a magnitude representative of the voltage of the fabric 3. Alternatively, it is the variations of this representative magnitude that trigger the deployment or withdrawal actions.

Un capteur et un procédé de mesure du couple exercé par l'actionneur sur le tube 21 sont, par exemple, décrits dans le brevet EP 1 269 596 (SOMFY ). Ce brevet décrit un dispositif pour arrêter le moteur lorsque la charge sur le moteur dépasse une valeur déterminée. Il comprend des moyens de transformation de la variation de la tension aux bornes du condensateur de déphasage correspondant à une variation de couple déterminée en une variation choisie de la tension quel que soit le couple maximum développé, des moyens de comparaison de la tension transformée avec une tension de référence et des moyens d'arrêt du moteur lorsque la tension transformée est inférieure à la tension de référence.A sensor and a method for measuring the torque exerted by the actuator on the tube 21 are, for example, described in the patent EP 1 269 596 (SOMFY ). This patent describes a device for stopping the motor when the load on the motor exceeds a determined value. It comprises means for transforming the variation of the voltage at the terminals of the phase-shift capacitor corresponding to a variation of torque determined in a selected variation of the voltage, whatever the maximum torque developed, means for comparing the voltage transformed with a voltage. reference voltage and means for stopping the motor when the transformed voltage is lower than the reference voltage.

Typiquement, ce capteur permet de mesurer un couple moteur ou résistant. Le couple est dit résistant lorsque le couple exercé par l'actionneur 6 est utilisé pour freiner le déploiement de la toile. A l'inverse, le couple est dit moteur lorsque l'actionneur 6 est commandé pour enrouler la toile 3.Typically, this sensor makes it possible to measure a motor or resistant torque. The torque is said to be resistant when the torque exerted by the actuator 6 is used to slow the deployment of the fabric. Conversely, the torque is said motor when the actuator 6 is controlled to wind the fabric 3.

Tout type de capteur permettant de mesurer une grandeur représentative de la tension de toile est envisageable, celui-ci ne faisant pas nécessairement partie de l'actionneur. Ainsi, un capteur mesurant directement la tension de toile ou un capteur mesurant des déplacements associés du tube par exemple entrent dans le cadre de l'invention.Any type of sensor for measuring a magnitude representative of the fabric tension is conceivable, it is not necessarily part of the actuator. Thus, a sensor directly measuring the tension of fabric or a sensor measuring associated displacements of the tube for example are within the scope of the invention.

Enfin, l'actionneur comprend un calculateur électronique 8 apte à exécuter l'un des procédés décrits en regard des figures 4 et 5. Ce calculateur 8 est typiquement un calculateur programmable associé à un support d'enregistrement d'informations contenant des instructions pour l'exécution de l'un de ces procédés.Finally, the actuator comprises an electronic calculator 8 capable of executing one of the methods described with regard to figures 4 and 5 . This calculator 8 is typically a programmable computer associated with a support information recording system containing instructions for executing one of these methods.

Lors de l'enroulement de la toile, l'actionneur 6 entraîne en rotation dans le deuxième sens le tube 21, ce qui a pour effet de tirer sur la toile 3 et de contraindre les bras 4 à se replier.During the winding of the fabric, the actuator 6 rotates in the second direction the tube 21, which has the effect of pulling on the fabric 3 and constrain the arms 4 to fold.

Les figures 2a à 2c permettent de visualiser les différentes étapes du procédé de commande du déploiement de la toile 3. Les figures 3a à 3c illustrent la variation du couple mesurée par le capteur 7, en fonction du temps, aux instants correspondant respectivement aux étapes des figures 2a à 2c.The Figures 2a to 2c allow to visualize the different steps of the control process of the deployment of the canvas 3. The Figures 3a to 3c illustrate the variation of the torque measured by the sensor 7, as a function of time, at the moments respectively corresponding to the steps of the Figures 2a to 2c .

Lors du déploiement de la toile 3, vu à la figure 2a, le tube d'enroulement tourne dans le premier sens, les bras 4 se déplient et la toile du store se déroule. On parle d'ouverture du store.When deploying the canvas 3, as seen in figure 2a , the winding tube rotates in the first direction, the arms 4 unfold and the awning fabric unfolds. We are talking about opening the blind.

Pendant cette phase, le capteur 7 mesure le couple d'entraînement de la toile, par exemple au niveau de l'axe de sortie de l'actionneur. Comme illustré, le couple mesuré n'est pas nécessairement constant en fonction du temps pendant cette étape, du fait d'une cinématique particulière liée à la fois aux ressorts des bras et à la commande de l'actionneur, qui permet de tendre la toile lors du mouvement. Toutefois, elle suit globalement une loi linéaire.During this phase, the sensor 7 measures the driving torque of the fabric, for example at the output axis of the actuator. As illustrated, the measured torque is not necessarily constant as a function of time during this step, because of a particular kinematics related to both the springs of the arms and the control of the actuator, which allows to stretch the fabric during the movement. However, it follows globally a linear law.

A la figure 2b, la toile est arrivée dans la position complètement déployée, c'est à dire que les bras 4 ne peuvent pas se déplier plus. Ici, c'est le mécanisme 11 qui empêche les bras de se déplier plus comme cela sera détaillé sur les figures 6a et 6b.To the figure 2b , the canvas arrived in the fully deployed position, that is to say that the arms 4 can not unfold anymore. Here, it is mechanism 11 that prevents the arms from unfolding more as will be detailed on the Figures 6a and 6b .

Au moment où la toile atteint sa position complètement déployée, pendant un court instant, les bras tirent fortement sur la toile avant que l'actionneur 6 ne poursuive le déroulement. La toile 3 continue alors de se dérouler légèrement et le couple mesuré (couple correspondant à la tension de la toile) chute brutalement dans la mesure où la toile détendue n'exerce plus de contrainte sur le tube d'enroulement et donc sur l'actionneur. Typiquement le couple mesuré tombe en-dessous d'un seuil S1. Le calculateur 8 détecte la variation brutale du couple mesuré et commande alors l'arrêt de la rotation et donc le blocage du tube.At the moment when the fabric reaches its fully extended position, for a short time, the arms pull strongly on the fabric before the actuator 6 continues the unwinding. Canvas 3 then continues to roll slightly and the measured torque (torque corresponding to the tension of the fabric) drops sharply to the extent that the relaxed web no longer exerts stress on the winding tube and therefore on the actuator. Typically the measured torque falls below a threshold S 1 . The computer 8 detects the sudden variation in the measured torque and then controls the stopping of the rotation and thus the locking of the tube.

L'installation est alors à l'arrêt mais la toile est détendue. Elle ne présente donc pas les caractéristiques souhaitées par les utilisateurs, tant au niveau esthétique que technique.The installation is then stopped but the canvas is relaxed. It does not present the characteristics desired by users, both aesthetically and technically.

La figure 3b illustre les variations du couple mesuré. La brusque chute B3 de couple est détectée sans confusion par le calculateur 8.The figure 3b illustrates the variations of the measured torque. The abrupt fall B3 of torque is detected without confusion by the computer 8.

Le calculateur 8 déclenche alors automatiquement une légère rotation du tube 21 dans le deuxième sens, ainsi que représenté à la figure 2c. Cette rotation a pour effet de tendre la toile, mais elle est stoppée avant que les bras 4 ne commencent à se replier.The computer 8 then automatically triggers a slight rotation of the tube 21 in the second direction, as shown in FIG. Figure 2c . This rotation has the effect of stretching the fabric, but it is stopped before the arms 4 begin to fold.

L'arrêt de l'enroulement peut être fonction du couple mesuré et/ou d'une durée prédéterminée.The termination of the winding can be a function of the measured torque and / or a predetermined duration.

Lors de l'enroulement, le couple mesuré augmente à nouveau comme on peut le voir sur la figure 3c. Ainsi, dans ce mode de réalisation particulier, le calculateur 8 arrête l'enroulement de la toile 3 dès que le couple mesuré dépasse un seuil prédéterminé S2. La valeur du seuil S2 est ajustée pour provoquer l'arrêt de l'enroulement de la toile 3 avant que les bras 4 ne commencent à se replier.During winding, the measured torque increases again as can be seen on the figure 3c . Thus, in this particular embodiment, the computer 8 stops the winding of the fabric 3 as soon as the measured torque exceeds a predetermined threshold S 2 . The value of the threshold S 2 is adjusted to stop the winding of the fabric 3 before the arms 4 begin to fold.

La figure 4 reprend sous forme d'organigramme les différentes étapes liées au déploiement de la toile et à la surveillance de la tension de la toile, ainsi que les liens entre ces deux aspects.The figure 4 The chart shows the various stages involved in the deployment of the canvas and the monitoring of the tension of the canvas, as well as the links between these two aspects.

Lors d'une étape P1, le début du déroulement de la toile est provoqué par un ordre d'un utilisateur. L'ordre est transmis, par exemple, à partir d'un point de commande fixé au mur ou à partir d'une télécommande mobile sans fil. Cet ordre provoque le début d'une étape P2 de surveillance du couple mesuré par le capteur 7.During a step P1, the start of the unwinding of the canvas is caused by a user's order. The order is transmitted, for example, from a control point attached to the wall or from a wireless mobile remote control. This command causes the start of a step P2 monitoring torque measured by the sensor 7.

Lors de l'étape P2, le capteur 7 mesure en continu un couple représentatif de la tension de la toile 3 et ce couple mesuré est comparé en temps réel au seuil S1. Une baisse de la tension de la toile est détectée si le couple mesuré tombe en dessous du seuil S1.During step P2, the sensor 7 continuously measures a torque representative of the voltage of the fabric 3 and this measured torque is compared in real time with the threshold S 1 . A drop in the tension of the fabric is detected if the measured torque falls below the threshold S 1 .

Lors d'une étape P3, les bras 4 arrivent en butée. Les bras se bloquent. Peu après l'arrivée en butée des bras, le calculateur 8 détecte une baisse de tension de la toile lors d'une étape P4.During a step P3, the arms 4 come to a stop. The arms are blocked. Shortly after the arrival of the arms, the computer 8 detects a voltage drop of the fabric during a step P4.

Par exemple, lors de l'étape P4, le calculateur 8 détecte uniquement une chute du couple mesuré si celle-ci est immédiatement précédée d'une augmentation du couple mesuré correspondant à la collision des bras avec une butée. A cet effet le calculateur 8 vérifie que 1a chute de tension détectée intervient dans un intervalle de temps Δt prédéterminé après que le couple mesuré ait dépassé un seuil prédéterminé. Par exemple, le seuil prédéterminé est égal au seuil S2 indiqué sur la figure 3b. L'intervalle Δt est ici choisi inférieur à 1 seconde et de préférence inférieur à 0,5 seconde.For example, during step P4, the computer 8 only detects a fall in the measured torque if it is immediately preceded by an increase in the measured torque corresponding to the collision of the arms with a stop. For this purpose the computer 8 verifies that the detected voltage drop occurs in a predetermined time interval Δt after the measured torque has exceeded a predetermined threshold. For example, the predetermined threshold is equal to the threshold S 2 indicated on the figure 3b . The interval Δt is here chosen less than 1 second and preferably less than 0.5 seconds.

En réponse à la détection d'une baisse de la tension de la toile, lors d'une étape P5, le calculateur 8 commande immédiatement l'arrêt de l'actionneur. Suite à cet arrêt, le calculateur 8 déclenche automatiquement, lors d'une étape P6, une rotation du tube 21 en sens inverse à celui qui vient d'avoir lieu. Ce mouvement d'enroulement déclenche instantanément une étape P7 de surveillance de l'arrêt de l'enroulement.In response to the detection of a decrease in the tension of the fabric, during a step P5, the computer 8 immediately commands the shutdown of the actuator. Following this stop, the computer 8 automatically triggers, during a step P6, a rotation of the tube 21 in the opposite direction to that which has just taken place. This winding movement instantly triggers a step P7 monitoring the winding stop.

L'étape P7 consiste, par exemple :

  • à vérifier si une durée prédéterminée décomptée depuis le début de l'étape P6 s'est écoulée, et/ou
  • à mesurer le couple représentatif de la tension de la toile 3 et à comparer ce couple au seuil S2.
Step P7 consists, for example:
  • checking whether a predetermined time counted since the beginning of step P6 has elapsed, and / or
  • to measure the torque representative of the tension of the fabric 3 and to compare this torque with the threshold S 2 .

Si lors d'une étape P8, le calculateur 8 détermine que la durée prédéterminée est écoulée ou que le couple mesuré a franchi le seuil S2, alors il commande automatiquement, lors d'une étape P9, l'arrêt de l'enroulement de la toile 3. La toile reste alors immobilisée dans sa position déployée tant qu'une nouvelle commande de déplacement n'est pas provoquée par l'utilisateur.If during a step P8, the computer 8 determines that the predetermined duration has elapsed or that the measured torque has crossed the threshold S 2 , then it automatically controls, during a step P9, the stop of the winding of 3. The canvas then remains immobilized in its deployed position as long as a new displacement command is not caused by the user.

Le seuil S2 est déterminé de manière fixe, par exemple en fonction de la surface de la toile, de la tension imposée au dispositif élastique 10 et/ou du type de butées des bras 4.The threshold S 2 is determined in a fixed manner, for example as a function of the surface of the fabric, the tension imposed on the elastic device 10 and / or the type of stops of the arms 4.

La valeur du seuil S2, ou de même, la durée d'enroulement de toile prédéterminée, peut également être réglée manuellement en exécutant le procédé de réglage de la figure 5.The value of the threshold S 2 , or likewise the predetermined web winding time, can also be set manually by executing the adjustment method of the figure 5 .

Au début du procédé de la figure 5, lors d'une étape P11, un utilisateur fait basculer le calculateur 8 dans un mode d'apprentissage.At the beginning of the process of figure 5 during a step P11, a user switches the computer 8 into a learning mode.

Ensuite, les étapes P1 à P5 du procédé de la figure 4 sont exécutées.Then, the steps P1 to P5 of the method of figure 4 are executed.

Toutefois, dans le mode d'apprentissage, le calculateur 8 ne procède pas automatiquement à l'étape P6. Au contraire, lors d'une étape P12, le calculateur 8 se met en attente d'une commande d'enroulement de la toile qui est provoquée manuellement par l'utilisateur. Ensuite, en réponse à cette commande d'enroulement, le calculateur 8 déclenche l'étape P6 et, en parallèle, lors d'une étape P13, le calculateur se met de nouveau en attente, mais cette fois-ci, d'une commande manuelle d'arrêt de l'enroulement.However, in the learning mode, the computer 8 does not proceed automatically to the step P6. On the contrary, during a step P12, the computer 8 is waiting for a winding command of the fabric that is caused manually by the user. Then, in response to this winding command, the computer 8 triggers the step P6 and, in parallel, during a step P13, the computer is put on standby again, but this time, a manual control shutdown of the winding.

Lorsque l'utilisateur constate que les bras sont sur le point de se replier, il provoque manuellement l'envoi de cette commande d'arrêt de l'enroulement. En réponse, l'étape P9 est exécutée et, en parallèle, lors d'une étape P14, le calculateur détermine et enregistre la valeur du seuil S2 ou la valeur de temps écoulée pendant le mouvement de repli. La valeur du seuil S2 est déterminée à partir de la valeur mesurée par le capteur 7 à l'instant où l'étape P9 a été déclenchée.When the user notices that the arms are about to fold back, he manually causes the sending of this command to stop the winding. In response, the step P9 is executed and, in parallel, during a step P14, the computer determines and records the value of the threshold S 2 or the value of elapsed time during the fallback movement. The value of the threshold S 2 is determined from the value measured by the sensor 7 at the moment when the step P9 has been triggered.

La valeur du seuil S2 ou la durée de repli ainsi définie par apprentissage peut être automatiquement modifiée pour tenir compte d'un temps de réaction de l'utilisateur.The value of the threshold S 2 or the fallback time thus defined by learning can be automatically modified to take account of a reaction time of the user.

Cet apprentissage est tout à fait compatible avec le mécanisme 11, en particulier réglable par l'utilisateur.This learning is fully compatible with the mechanism 11, in particular adjustable by the user.

La figure 6a présente un exemple de mécanisme 11 sous forme de butée réglable, pour un bras 4. Ce dispositif limite le débattement mécanique des bras de manière réglable.The figure 6a shows an example of mechanism 11 in the form of adjustable stop for an arm 4. This device limits the mechanical movement of the arms in an adjustable manner.

Dans le mode de réalisation de la figure 6a, le mécanisme 11 comprend une vis 110 de réglage, montée par vissage dans un ergot taraudé 111. L'ergot 111 est fixé, sans aucun degré de liberté, au premier segment 41 du bras 4 ou à la charnière 43 du bras 4. Une extrémité de la vis 110 vient en butée sur un ergot 112 fixé sur le deuxième segment 42 du bras 4 lorsque le bras 4 est dans une position complètement dépliée. Ainsi, la vis 110 permet de régler la valeur αmax en la vissant plus ou moins à l'intérieur de l'ergot 111.In the embodiment of the figure 6a , the mechanism 11 comprises a setting screw 110, mounted by screwing in a threaded lug 111. The lug 111 is fixed, without any degree of freedom, to the first segment 41 of the arm 4 or to the hinge 43 of the arm 4. A end of the screw 110 abuts a lug 112 attached to the second segment 42 of the arm 4 when the arm 4 is in a fully unfolded position. Thus, the screw 110 makes it possible to adjust the value α max by screwing it more or less inside the lug 111.

On peut également imaginer une butée élastique, permettant d'amortir le choc entre l'extrémité de la vis 110 et l'ergot 112, de manière à préserver les éléments de l'installation.One can also imagine an elastic stop, to dampen the shock between the end of the screw 110 and the lug 112, so as to preserve the elements of the installation.

Un deuxième mode de réalisation du mécanisme 11 est représenté sur la figure 6b. Il permet, en plus de maintenir la valeur de l'angle α inférieure à 180°, de retenir les bras dans la position complètement déployée. A cet effet, un premier ergot 113 fixé, sans aucun degré de liberté, sur la charnière 43 du bras 4 supporte une patte 114 flexible, à l'extrémité de laquelle est montée une protubérance 115.A second embodiment of the mechanism 11 is shown on the figure 6b . It allows, in addition to maintaining the value of the angle α less than 180 °, to hold the arms in the fully deployed position. For this purpose, a first pin 113 fixed, without any degree of freedom, on the hinge 43 of the arm 4 supports a flexible tab 114, at the end of which is mounted a protuberance 115.

Un deuxième ergot 116 est fixé sur le deuxième segment 42 du bras 4.A second pin 116 is fixed on the second segment 42 of the arm 4.

De préférence, la protubérance 115 et/ou l'ergot 116 présentent des surfaces inclinées par rapport à une direction F de déplacement relatif de la protubérance 115 par rapport à l'ergot 116. Sur la figure 6b, seule la protubérance 115 présente une surface inclinée 115a par rapport à la direction F.Preferably, the protuberance 115 and / or the lug 116 have surfaces inclined relative to a direction F of relative displacement of the protuberance 115 relative to the lug 116. figure 6b only the protuberance 115 has an inclined surface 115a with respect to the direction F.

Les ergots 113 et 116, la patte 114 et la protubérance 115 forment un mécanisme de retenue propre à maintenir l'angle α dans une plage de +/- X° autour de la valeur αmax tant qu'un effort de traction exercé sur les bras pour réduire cet angle reste inférieur à un seuil prédéfini de traction. Par exemple, X est inférieur ou égal à 5°.The lugs 113 and 116, the tab 114 and the protuberance 115 form a retaining mechanism adapted to maintain the angle α in a range of +/- X ° around the value α max as long as a tensile force exerted on the arm to reduce this angle remains below a predefined threshold of traction. For example, X is less than or equal to 5 °.

De préférence, la protubérance 115 est déplaçable le long de la patte 114 dans au moins une direction contenue dans le plan de déplacement des bras 4. Cette possibilité de modifier la position de la protubérance 115 permet de régler la valeur X.Preferably, the protuberance 115 is displaceable along the lug 114 in at least one direction contained in the plane of movement of the arms 4. This possibility of modifying the position of the protuberance 115 makes it possible to adjust the value X.

De plus, la flexibilité de la patte elle-même peut être ajustée. Ceci permet de définir la valeur d'un seuil de traction au-delà duquel le déverrouillage des bras 4 devient possible, comme on le comprendra à la lecture de ce qui suit.In addition, the flexibility of the tab itself can be adjusted. This makes it possible to define the value of a pull threshold beyond which the unlocking of the arms 4 becomes possible, as will be understood on reading the following.

Lors du déploiement des bras 4, l'ergot 116 rencontre la surface inclinée 115a de la protubérance 115. Toutefois, la déformation de la patte 114 permet à l'ergot 116 de passer sous la protubérance 115. La coopération de l'ergot 116 avec la protubérance 115 forme une butée escamotable provoquant une chute de la tension de la toile. Après avoir passé cette butée escamotable, les ergots 113 et 116 peuvent venir en butée pour limiter mécaniquement le déploiement de la toile. Un moyen de réglage tel que décrit en référence à la figure 6a peut également être mis en oeuvre dans ce mode de réalisation.During the deployment of the arms 4, the lug 116 meets the inclined surface 115a of the protrusion 115. However, the deformation of the lug 114 allows the lug 116 to pass under the protrusion 115. The cooperation of the lug 116 with the protrusion 115 forms a retractable stop causing a drop in the tension of the fabric. After passing this retractable stop, the lugs 113 and 116 may come into abutment to mechanically limit the deployment of the fabric. An adjustment means as described with reference to the figure 6a can also be implemented in this embodiment.

Les bras 4 se trouvent alors dans une position de verrouillage, indépendante des ressorts de tension des bras, propre à maintenir la toile dans sa position complètement déployée.The arms 4 are then in a locking position, independent of the tension springs of the arms, able to keep the fabric in its fully extended position.

Pour déverrouiller les bras 4, il faut également fournir un couple de déverrouillage des bras, ce couple étant cependant nettement inférieur à celui nécessaire au déverrouillage de bras arc-boutés.To unlock the arms 4, it is also necessary to provide arm unlocking torque, this torque being however much lower than that required for unlocking arched arms.

Lors du déploiement de la toile 3, le passage de la protubérance 115 provoque une chute du couple mesuré, ce qui permet de détecter la proximité de la position complètement déployée. En réponse, dans ce mode de réalisation, le calculateur 8 arrête automatiquement, après une durée prédéterminée, le déroulement de la toile 3. Cette durée est ici prédéterminée, pour laisser assez de temps pour que l'ergot 116 passe la protubérance 115 et que les bras soient ainsi dans leur position de verrouillage. Il n'est pas nécessaire que cette durée soit suffisamment longue pour que l'ergot 116 vienne buter sur l'ergot 113.During deployment of the fabric 3, the passage of the protrusion 115 causes a fall in the measured torque, which makes it possible to detect the proximity of the fully deployed position. In response, in this embodiment, the computer 8 stops automatically, after a predetermined duration, the unwinding of the fabric 3. This duration is here predetermined, to allow enough time for the lug 116 to pass the protrusion 115 and that the arms are thus in their locking position. It is not necessary that this duration be long enough for the lug 116 to abut on the lug 113.

La courbe de couple en fonction du temps est alors similaire à celle représentée à la figure 3b.The torque versus time curve is then similar to that shown in FIG. figure 3b .

Lors du mouvement d'enroulement permettant de tendre la toile 3, il est également plus facile d'arrêter automatiquement le mouvement avant le passage de cette protubérance 115. En effet, le passage de la protubérance 115 correspond à une augmentation importante du couple mesuré. Le seuil S2, peut alors facilement être déterminé par apprentissage.During the winding movement to stretch the fabric 3, it is also easier to stop automatically the movement before the passage of this protrusion 115. Indeed, the passage of the protrusion 115 corresponds to a significant increase in the measured torque. The threshold S 2 can then easily be determined by learning.

D'autres systèmes de butée et/ou de fixation de la valeur αmax peuvent bien entendu être envisagés sans sortir du cadre de l'invention. C'est le cas par exemple d'une butée à bille ou d'une dispositif de retenue à aimant, tel que décrit par exemple dans la demande de brevet EP1273733 .Other stop systems and / or fixing the value α max can of course be considered without departing from the scope of the invention. This is the case, for example, of a ball stop or a magnet retaining device, as described, for example, in the application for EP1273733 .

L'invention trouve une application particulièrement intéressante dans le cadre des stores dits autonomes, c'est à dire fonctionnant grâce à une source d'énergie non reliée à un réseau électrique et éventuellement rechargeable (par exemple grâce à des cellules photovoltaïques).The invention finds a particularly interesting application in the context of so-called autonomous blinds, that is to say functioning thanks to a power source not connected to an electrical network and possibly rechargeable (for example thanks to photovoltaic cells).

En effet, il est particulièrement important dans ce cas de limiter la consommation, et donc de limiter la puissance nécessaire à fournir par l'actionneur lors de l'actionnement du store, tout en conservant une toile suffisamment tendue.Indeed, it is particularly important in this case to limit the consumption, and therefore to limit the power required to provide the actuator during actuation of the blind, while maintaining a sufficiently taut canvas.

Les différentes fonctionnalités liées généralement aux stores sont tout à fait applicables en combinaison avec ce qui vient d'être décrit. Par exemple l'accostage en butée à tension d'alimentation ou vitesse réduite, le déstressage de la toile, l'utilisation conjointe de capteurs (d'ensoleillement, de vent, etc) peuvent être mis en oeuvre dans les modes de réalisation ci-dessus.The various features generally related to blinds are quite applicable in combination with what has just been described. For example docking in abutment with reduced supply voltage or speed, the de-stressing of the fabric, the joint use of sensors (sunlight, wind, etc.) can be implemented in the embodiments described above. above.

D'autres avantages liés à l'invention sont détaillés ci-dessous :

  • un compteur de position n'est pas nécessaire, le store peut évoluer entre ses positions extrêmes (d'un côté le coffre et de l'autre, la butée, escamotable ou pas, sur les bras). Cette structure simplifie alors l'actionneur qui peut être plus facilement rendu étanche (en effet, les dispositifs de comptage sont des points d'entrée pour l'humidité, ce qui représente une contrainte de fabrication dans la mesure où un tel store est placé en extérieur),
  • les butées peuvent également être utilisées pour recaler la position en cas d'utilisation d'une manoeuvre manuelle dans un système hors alimentation et à comptage électronique.
Other advantages related to the invention are detailed below:
  • a position counter is not necessary, the blind can move between its extreme positions (on one side the chest and on the other, the stop, retractable or not, on the arms). This structure then simplifies the actuator which can be more easily sealed (indeed, the counting devices are points of entry for moisture, which represents a manufacturing constraint to the extent that such a blind is placed outside),
  • the stops can also be used to reset the position when using a manual operation in a non-power and electronic counting system.

Un autre avantage est lié à la détection d'obstacle à la descente d'un store. La variation de tension de la toile détectée pourrait également être due à la présence d'un obstacle sur la zone de déploiement du store (par exemple présence d'un camion devant un store de terrasse de café). Dans ce cas, le déploiement du store est arrêté, conformément à l'invention.Another advantage is related to the obstacle detection at the descent of a blind. The voltage variation of the detected fabric could also be due to the presence of an obstacle on the deployment area of the blind (for example presence of a truck in front of a coffee terrace awning). In this case, the deployment of the blind is stopped, according to the invention.

En variante, le calculateur 8 et/ou le capteur 7 sont montés en dehors de l'actionneur.Alternatively, the computer 8 and / or the sensor 7 are mounted outside the actuator.

Dans d'autres modes de réalisation, chaque bras 4 peut se déplier dans son propre plan de déplacement parallèle au plan de déplacement de l'autre bras.In other embodiments, each arm 4 can unfold in its own plane of displacement parallel to the plane of movement of the other arm.

Ici, l'installation de store a été décrite dans le cas particulier où l'étape P6 d'enroulement est arrêtée automatiquement en fonction d'une durée prédéterminée ou du dépassement du seuil S2. En variante, l'étape P6 d'enroulement de la toile est automatiquement arrêtée en fonction d'une distance angulaire prédéterminée. Par exemple, l'actionneur 6 est automatiquement arrêté dès que le tube 21 a parcouru cette distance angulaire prédéterminée.Here, the awning installation has been described in the particular case where the winding step P6 is automatically stopped according to a predetermined duration or exceeding the threshold S 2 . Alternatively, the step P6 of winding of the fabric is automatically stopped according to a predetermined angular distance. For example, the actuator 6 is automatically stopped as soon as the tube 21 has traveled this predetermined angular distance.
