Description

L'invention a trait à un dispositif d'actionnement d'un organe de débrayage pour un motoréducteur d'entraínement en rotation d'un tube d'enroulement d'une installation de fermeture ou de protection solaire.The invention relates to a device for actuating a declutching member for a geared motor drive rotation of a winding tube of a closing installation or sun protection.

Par installation de fermeture, on entend les portes, portails, volets et matériels équivalents.The term “closing installation” means the doors, gates, shutters and equivalent equipment.

Il est connu d'utiliser un moteur électrique pour entraíner en rotation un arbre d'enroulement d'un tablier de porte ou de volet ou un store de protection solaire. Il est également connu, par exemple de EP-A-0 597 780, de prévoir une épingle élastique de débrayage d'un tel motoréducteur afin de permettre sa manoeuvre manuelle, notamment en cas de panne d'alimentation électrique. L'épingle ou organe de débrayage est commandé grâce à un câble gainé relié à un dispositif d'actionnement. En agissant sur le dispositif d'actionnement, l'utilisateur tire au moyen du câble sur l'organe de débrayage du motoréducteur, ce qui permet de le désaccoupler du tube d'enroulement précité. D'autres types d'organes de débrayage sont également connus de la technique antérieure, notamment des organes de libération d'un frein associé au motoréducteur tels que décrits dans FR-A-2 612 246.It is known to use an electric motor to drive in rotation a winding shaft of a door leaf or shutter or a sun protection blind. It is also known, for example from EP-A-0 597 780, to provide a elastic release pin of such a gearmotor in order to allow manual operation, especially in the event of a breakdown power supply. The pin or declutching device is controlled by a sheathed cable connected to a device actuating. By acting on the actuating device, the user pulls by means of the cable on the release member of the gearmotor, which allows it to be uncoupled from the tube above winding. Other types of clutch release devices are also known from the prior art, in particular brake release members associated with the gearmotor as described in FR-A-2 612 246.

Par ailleurs, il est connu de FR-A-2 647 152 de réaliser un levier de débrayage de type "à course définie". En fonction de la longueur de la gaine du câble et de son cheminement qui peut être rectiligne ou tortueux selon les configurations d'installation, la course nécessaire au niveau du dispositif d'actionnement pour passer d'une situation embrayée à une situation débrayée au niveau du motoréducteur est différente. En d'autres termes, la position du dispositif d'actionnement qui correspond effectivement à une situation débrayée du motoréducteur varie d'une installation à l'autre, sauf à prévoir un réglage précis, lequel se révèle long, fastidieux et susceptible de dérive au cours du temps. En pratique, un utilisateur prend généralement une marge de manoeuvre en forçant sur le dispositif d'actionnement jusqu'à sentir un effort résistant, au risque de détériorer l'organe de débrayage et d'accentuer une éventuelle dérive du réglage du dispositif d'actionnement au point de ne plus pouvoir obtenir de débrayage après plusieurs utilisations.Furthermore, it is known from FR-A-2 647 152 to carry out a "defined stroke" type release lever. Depending the length of the cable sheath and its path which can be straight or tortuous depending on the configuration installation, the necessary stroke at the device of actuation to pass from a engaged situation to a situation disengaged at the gearmotor is different. In other words, the position of the actuator which actually corresponds to a disengaged situation of the gearmotor varies from one installation to another, except for provide a precise adjustment, which turns out to be long, tedious and likely to drift over time. In practice, a user usually takes some leeway in forcing on the actuating device until you feel a resistant effort, at the risk of damaging the declutching and accentuate any drift in the adjustment of the actuation device to the point of no longer being able to obtain release after several uses.

C'est à ces problèmes qu'entend plus particulièrement remédier l'invention en proposant un dispositif d'actionnement dont la course correspondant au débrayage peut être immédiatement identifiée par un utilisateur, indépendamment de la configuration de l'installation de fermeture ou de protection solaire.It is to these problems that we hear more particularly remedy the invention by proposing an actuation device whose travel corresponding to the clutch can be immediately identified by a user, regardless of the configuration of the locking or protection installation solar.

Dans cet esprit, l'invention concerne un dispositif du type précité qui comprend au moins des moyens d'alimentation électrique, avec une différence de potentiel, du câble et d'une armature, électriquement conductrice, incluse dans une gaine isolante entourant ce câble, ce câble et cette armature étant aptes à être raccordés électriquement en fonction de la position de l'organe de débrayage.In this spirit, the invention relates to a device of the aforementioned type which comprises at least supply means electrical, with potential difference, cable and an armature, electrically conductive, included in a insulating sheath surrounding this cable, this cable and this frame being able to be electrically connected according to the position of the declutching member.

Grâce à l'invention, la position effective de l'organe de débrayage peut être détectée par le raccordmeent électrique du câble et de l'armature, ce raccordement pouvant être modélisé par la fermeture d'un interrupteur raccordé d'une part au câble et d'autre part à l'armature, cet interrupteur pouvant être intégré dans une boucle de contrôle électrique. En d'autres termes, dès que l'organe de débrayage a atteint une position dans laquelle il connecte le câble et l'armature, il permet de signaler à l'utilisateur que la configuration débrayée du motoréducteur est atteinte, l'utilisateur pouvant alors cesser la manoeuvre correspondante avant de risquer d'endommager les éléments constitutifs du motoréducteur, du système de débrayage ou du dispsoitif d'actionnement.Thanks to the invention, the effective position of the organ clutch can be detected by the electrical connection cable and armature, this connection can be modeled by the closing of a switch connected to a part to the cable and secondly to the armature, this switch can be integrated into an electrical control loop. In other words, as soon as the release member has reached a position in which it connects the cable and the armature, it lets the user know that the configuration disengaged from the gearmotor is reached, the user being able to then stop the corresponding maneuver before risking damage the components of the gearmotor, declutching system or actuating device.

Selon des aspects avantageux mais non obligatoires de l'invention, le dispositif incorpore une ou plusieurs des caractéristiques suivantes :

  • Au moins un indicateur d'état est connecté entre le câble et l'armature. Cet indicateur peut être de type lumineux, par exemple une lampe ou une diode électro-luminescente, ou de type sonore, par exemple un buzzer. Dans tous les cas, cet indicateur permet de signaler directement à l'utilisateur que la configuration débrayée du motoréducteur est atteinte et ce indépendamment de la configuration de l' installation, et en particulier du cheminement de la gaine.
  • Le dispositif comprend un premier composant formant une surface de butée de la gaine et un second composant vissé sur ou dans le premier composant, ces premier et second composants étant chacun percés d'un canal longitudinal de passage du câble, la seconde extrémité du câble étant solidaire d'un poussoir en appui contre une face du second composant opposée au premier composant. Cette structure du dispositif permet de commander le déplacement du câble par rapport à la gaine en écartant plus ou moins les composants l'un par rapport à l'autre, ce qui revient à augmenter ou à diminuer la distance entre l'extrémité de la gaine en appui sur le premier composant et l'extrémité du câble indirectement en appui contre le second composant. De façon avantageuse, des parties vissées ensemble des premier et second composants sont électriquement conductrices et forment une partie de liaison électrique entre le câble et l'armature. Dans ce cas, un canal central de l'une au moins de ces parties vissées peut être revêtu intérieurement d'une couche d'isolation électrique entre cette partie et le câble. Par ailleurs, on peut prévoir que le premier composant comprend un corps électriquement conducteur en contact électrique avec l'armature et/ou que le second comprend un corps électriquement isolant, qui supporte une source de tension et au moins un indicateur d'état, cette source de tension et cet indicateur étant raccordés en série entre le câble et l'armature.
  • Le dispositif comprend un support électriquement conducteur formant surface de butée de la gaine au niveau de la première extrémité du câble et apte à recevoir en appui l'organe de débrayage, également électriquement conducteur en fonction de la tension du câble.
According to advantageous but not compulsory aspects of the invention, the device incorporates one or more of the following characteristics:
  • At least one status indicator is connected between the cable and the armature. This indicator can be of the light type, for example a lamp or an electroluminescent diode, or of the sound type, for example a buzzer. In all cases, this indicator makes it possible to signal directly to the user that the disengaged configuration of the gearmotor has been reached, regardless of the configuration of the installation, and in particular the path of the sheath.
  • The device comprises a first component forming an abutment surface of the sheath and a second component screwed onto or into the first component, these first and second components each being pierced with a longitudinal cable passage channel, the second end of the cable being secured to a pusher bearing against a face of the second component opposite to the first component. This structure of the device makes it possible to control the movement of the cable relative to the sheath by deviating more or less the components from one another, which amounts to increasing or decreasing the distance between the end of the sheath bearing on the first component and the end of the cable indirectly bearing against the second component. Advantageously, parts screwed together of the first and second components are electrically conductive and form a part of electrical connection between the cable and the armature. In this case, a central channel of at least one of these screwed parts can be coated internally with a layer of electrical insulation between this part and the cable. Furthermore, it can be provided that the first component comprises an electrically conductive body in electrical contact with the armature and / or that the second comprises an electrically insulating body, which supports a voltage source and at least one status indicator, this voltage source and this indicator being connected in series between the cable and the armature.
  • The device comprises an electrically conductive support forming an abutment surface of the sheath at the first end of the cable and capable of receiving the declutching member in support, also electrically conductive as a function of the cable tension.

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

  • la figure 1 est un schéma électrique de principe d'un dispositif conforme à l'invention ;
  • la figure 2 est une coupe longitudinale du dispositif représenté schématiquement à la figure 1 dans une première configuration d'utilisation et
  • la figure 3 est une vue analogue à la figure 2 dans une seconde configuration d'utilisation du dispositif.
The invention will be better understood and other advantages thereof will appear more clearly in the light of the following description of an embodiment of a device in accordance with its principle, given solely by way of example and made with reference to the accompanying drawings in which:
  • Figure 1 is an electrical block diagram of a device according to the invention;
  • FIG. 2 is a longitudinal section of the device shown schematically in FIG. 1 in a first configuration of use and
  • Figure 3 is a view similar to Figure 2 in a second configuration of use of the device.

Le dispositif 1 représenté sur les figures est destiné à commander une épingle de débrayage 2 du type décrit dans EP-A-0 597 780, un dispositif de commande de frein du type décrit dans FR-A-2 612 246 ou tout autre type d'organe de débrayage similaire.The device 1 shown in the figures is intended to order a release pin 2 of the type described in EP-A-0 597 780, a brake control device of the type described in FR-A-2 612 246 or any other type of declutching device similar.

Le dispositif 1 se décompose en une partie 1A disposée au niveau du motoréducteur, c'est-à-dire à proximité de l'arbre d'enroulement d'un tablier de volet roulant ou d'un store, et en une partie 1B formant poignée de manoeuvre et destinée à être prise en main par un utilisateur. Un câble 3 s'étend entre les parties 1A et 1B à l'intérieur d'une gaine 4 disposée selon un cheminement qui dépend de la configuration de l'installation de fermeture ou de protection solaire. On note 3A la première extrémité du câble 3 du côté de la partie 1A du dispositif et 3B la seconde extrémité de ce câble du côté de la partie 1B. De la même manière, on note respectivement 4A et 4B les extrémités de la gaine 4 disposées respectivement du côté des parties 1A et 1B du dispositif 1.The device 1 is broken down into a part 1A arranged at the gearmotor, i.e. close to the winding shaft of a roller shutter curtain or a blind, and in a part 1B forming an operating handle and intended to be taken in hand by a user. A cable 3 extends between parts 1A and 1B inside a sheath 4 arranged according to a path which depends on the configuration of the closing or sun protection installation. We note 3 At the first end of the cable 3 on the side of the part 1A of the device and 3B the second end of this cable from the side of part 1B. In the same way, we note respectively 4A and 4B the ends of the sheath 4 disposed respectively on the side of parts 1A and 1B of the device 1.

Comme il ressort plus particulièrement de la figure 1, l'épingle 2 est utilisée comme la partie mobile d'un interrupteur 5 prévu dans la partie 1A, alors que la partie 1B comprend une batterie d'accumulateurs 6 et un indicateur 7 formé par diode électro-luminescente. L'interrupteur 5 est configuré de telle sorte que l'épingle 2 ferme l'interrupteur lorsqu'elle est en position de débrayage du motoréducteur, auquel cas la diode électro-luminescente 7 est éclairée grâce à la différence de potentiel aux bornes de la batterie 6. Les deux lignes L1 et L2 de liaison électrique entre les parties 1A et 1B sont respectivement formées, sur la plus grande partie de leur longueur, par le câble 3, qui est métallique, et par une armature métallique 4C prévue dans la gaine 4 et noyée à l'intérieur de celle-ci, entre une couche isolante interne 4D et une couche isolante externe 4E de la gaine 4. As can be seen more particularly from FIG. 1, the pin 2 is used as the movable part of a switch 5 provided in part 1A, while part 1B comprises a storage battery 6 and an indicator 7 formed by diode electro-luminescent. The switch 5 is configured so that the pin 2 closes the switch when it is in the disengaged position of the gearmotor, in which case the light-emitting diode 7 is lit by virtue of the potential difference at the terminals of the battery. 6. The two lines L 1 and L 2 of electrical connection between the parts 1A and 1B are respectively formed, over most of their length, by the cable 3, which is metallic, and by a metallic reinforcement 4C provided in the sheath 4 and embedded inside of it, between an internal insulating layer 4D and an external insulating layer 4E of the sheath 4.

Ainsi, la fonction de contrôle du bon positionnement de l'épingle 2 grâce aux éléments 5 à 7 est obtenue sans ajout d'une liaison électrique supplémentaire entre les parties 1A et 1B du dispsositif, le câble 3 et la gaine 4 étant, en toute hypothèse, utilisés pour la manoeuvre de l'épingle 2.Thus, the function of controlling the correct positioning of pin 2 thanks to elements 5 to 7 is obtained without addition an additional electrical connection between parts 1A and 1B of the device, the cable 3 and the sheath 4 being, in all hypothesis, used for the operation of the pin 2.

La structure et le mode de fonctionnement du dispositif 1 ressortent plus particulièrement des figures 2 et 3.The structure and mode of operation of the device 1 appear more particularly from FIGS. 2 and 3.

L'extrémité 4A de la gaine 4 est en appui contre un support 8 électriquement conducteur, par exemple métallique, fixé à proximité du motoréducteur de l'installation et dont la surface 8A tournée vers la gaine 4 forme un logement 8B de réception de l'extrémité 4A de cette gaine. Comme l'armature 4C de la gaine 4 est affleurante au niveau de l'extrémité 4A, les éléments 8 et 4C sont électriquement reliés.The end 4A of the sheath 4 is in abutment against a electrically conductive support 8, for example metallic, fixed near the geared motor of the installation and whose the surface 8A facing the sheath 4 forms a housing 8B of reception of the end 4A of this sheath. As the frame 4C of the sheath 4 is flush with the end 4A, elements 8 and 4C are electrically connected.

Par ailleurs, après avoir traversé un alésage central 8C du support 8 et un orifice 2C de l'épingle 2, l'extrémité 3A du câble est engagée dans un serre-câble 9 équipé d'une vis de blocage 9A. Ainsi, en fonction de la tension T du câble 3, le serre-câble 9 vient en appui contre une surface 2A de l'épingle 2 opposée au support 8 et est apte à déplacer l'épingle 2 en direction du support 8 comme représenté par la flèche F1.Furthermore, after passing through a central bore 8C of the support 8 and an orifice 2C of the pin 2, the end 3A of the cable is engaged in a cable clamp 9 equipped with a locking screw 9A. Thus, as a function of the tension T of the cable 3, the cable clamp 9 comes to bear against a surface 2A of the pin 2 opposite the support 8 and is able to move the pin 2 in the direction of the support 8 as shown by arrow F 1 .

La seconde extrémité 4B de la gaine 4 est engagée dans un premier composant 10 dont la face 10A tournée vers la gaine 4 forme un logement de réception 10B de cette extrémité. Le composant 10 est formé d'un corps électriquement conducteur 10C, par exemple métallique, et d'une partie filietée 10D, également électriquement conductrice, immobilisée par coopération de formes à l'intérieur d'un logement 10E du corps 10C. On note 10F le filet de la partie 10D.The second end 4B of the sheath 4 is engaged in a first component 10 whose face 10A faces the sheath 4 forms a receiving housing 10B for this end. The component 10 is formed from an electrically conductive body 10C, for example metallic, and a threaded part 10D, also electrically conductive, immobilized by cooperation of shapes inside a housing 10E of the body 10C. We note 10F the net of part 10D.

Un second composant 11 est formé d'un corps électriquement isolant 11A et d'un écrou 11B électriquement conducteur et immobilisé par coopération de formes dans un logement 11C disposé au niveau du débouché d'un alésage central 11D du corps 11A.A second component 11 is formed from an electrically body insulator 11A and an electrically conductive nut 11B and immobilized by cooperation of forms in an 11C housing arranged at the outlet of a central bore 11D of the body 11A.

L'extrémité 3B du câble 3 traverse successivement un alésage central 10G du corps 10C, un alésage central 10H de la partie filetée 10D, l'alésage 11D et un second alésage 11E ménagé dans la paroi de fond du corps 11A. Un serre-câble 12, électriquement conducteur et équipé d'une vis 12A, est serré sur cette extrémité 3B et vient en appui contre une surface d'extrémité 11F du corps 11.The end 3B of the cable 3 passes successively through a 10G central bore of body 10C, a 10H central bore of the threaded portion 10D, the bore 11D and a second bore 11E formed in the bottom wall of the body 11A. A cable clamp 12, electrically conductive and fitted with a 12A screw, is tightened on this end 3B and bears against a surface 11F end of the body 11.

Une gaine électriquement isolante 13 est disposée dans l'alésage 10H autour du câble 3, de telle sorte qu'une isolation électrique effective est garantie entre le câble 3 et la partie 10D.An electrically insulating sheath 13 is arranged in the 10H bore around the cable 3, so that insulation effective electric power is guaranteed between cable 3 and part 10D.

Une semelle 14 électriquement conductrice relie le serre-câble 12 à une borne de la batterie 6 dont la seconde borne est reliée, par un conducteur électrique 15 à une borne de la diode électro-luminescente 7 alors qu'un second conducteur 16 relie la seconde borne de la diode électro-luminescente 7 à l'écrou 11B dans le corps 11A.An electrically conductive sole 14 connects the cable clamp 12 to one terminal of battery 6 including the second terminal is connected, by an electrical conductor 15 to a terminal of the light-emitting diode 7 while a second conductor 16 connects the second terminal of the light-emitting diode 7 to the nut 11B in the body 11A.

Ainsi, lorsqu'il convient de débrayer le motoréducteur de l'installation considérée, l'utilisateur peut dévisser le composant 11 par rapport au composant 10, ce qui a pour effet d'augmenter la tension T dans le câble 3 et de déplacer l'épingle 2 dans le sens de la flèche F1. La configuration des éléments 2 et 8 est choisie de telle sorte que l'épingle 2 vient en appui contre le support 8 lorsque le motoréducteur est débrayé comme représenté à la figure 3. Dans cette position, l'interrupteur 5 schématisé à la figure 1 est fermé par le contact des éléments 2 et 8.Thus, when it is necessary to disengage the geared motor from the installation considered, the user can unscrew the component 11 relative to the component 10, which has the effect of increasing the tension T in the cable 3 and of displacing the pin 2 in the direction of arrow F 1 . The configuration of elements 2 and 8 is chosen so that the pin 2 comes to bear against the support 8 when the gearmotor is disengaged as shown in FIG. 3. In this position, the switch 5 shown diagrammatically in FIG. 1 is closed by the contact of elements 2 and 8.

La ligne L1 est formée par l'épingle 2, le serre câble 9, le câble 3, le serre câble 12 et la semelle 14 alors que la ligne L2 est formée par le conducteur 16, l'écrou 11B, la partie 10D, le corps 10C, l'armature 4C et le support 8.Line L 1 is formed by pin 2, cable clamp 9, cable 3, cable clamp 12 and sole 14 while line L 2 is formed by conductor 16, nut 11B, part 10D , the body 10C, the armature 4C and the support 8.

Lorsque l'épingle 2 entre en contact avec le support 8, la diode électro-luminescente 7 s'allume et l'utilisateur est immédiatement informé qu'un déplacement suffisant de l'épingle 2 a été opéré et qu'il n'est pas nécessaire de dévisser plus avant le composant 11 par rapport au composant 10. L'utilisateur ne risque donc pas d'endommager l'épingle 2 ou les éléments périphériques s'il respecte l'information donnée par par la diode électro-luminescente 7, indépendamment du cheminement éventuellement tortueux de la gaine dans l'installation. D'autres indicateurs peuvent être utilisés à la place de la diode 7 tels que par exemple une lampe, un buzzer, un système d'affichage à écran, un système de transmission par ondes radio ou un vibreur.When the pin 2 comes into contact with the support 8, the light-emitting diode 7 lights up and the user is immediately informed that sufficient displacement of the pin 2 has been operated and it is not necessary to unscrew more before component 11 compared to component 10. The user therefore does not risk damaging pin 2 or peripheral elements if it respects the information given by by the light-emitting diode 7, independently of the possibly tortuous path of the sheath in the installation. Other indicators can be used in place of diode 7 such as for example a lamp, a buzzer, a screen display system, a transmission system by radio waves or a vibrator.
