Description

La présente invention concerne un système de commande de lames de jalousie et une jalousie correspondante.The present invention relates to a control system of leaf blades and a corresponding jalousie.

Une jalousie est une menuiserie destinée à réaliser la fermeture d'une ouverture réalisée dans une paroi, ou baie, à l'aide de lames verticales ou horizontales (cas le plus fréquent) montées pivotantes. Les lames sont généralement toutes disposées sensiblement parallèlement les unes par rapport aux autres et pivotent de manière soit à réaliser une fermeture de la baie, soit à permettre une aération. En position fermée, les lames peuvent être soit coplanaires et venir au contact l'une de l'autre pour assurer une fermeture, soit disposées les unes par rapport aux autres de manière à réaliser un recouvrement partiel à la manière de tuiles. Généralement, des moyens de commande sont prévus pour permettre une rotation simultanée des lames de la jalousie.A jalousie is a joinery intended to close an opening made in a wall, or bay, using vertical or horizontal blades (the most common case) mounted pivoting. The blades are generally all arranged substantially parallel to each other and rotate so as to achieve a closure of the bay, or to allow aeration. In the closed position, the blades can be coplanar and come into contact with one another to ensure a closure, or arranged relative to each other so as to achieve a partial recovery in the manner of tiles. Generally, control means are provided to allow a simultaneous rotation of the blades of the blind.

La présente invention concerne plus particulièrement une jalousie pour laquelle un système de commande agit simultanément sur tout ou partie des lames. La jalousie présente habituellement un châssis rectangulaire avec deux montants latéraux reliés par deux traverses. Les lames sont solidaires d'un axe dont les extrémités sont montées dans les montants latéraux (pour des lames horizontales) ou dans les traverses (pour des lames verticales). Classiquement, la commande d'ouverture et de fermeture de la jalousie, et donc le pivotement des lames, s'effectue par un système à tringle et biellettes disposé de part et d'autre des lames. Chaque lame porte à chacune de ses extrémités un élément appelé entraîneur et qui est relié par vissage à une biellette du système de commande. Une poignée de commande agit alors sur une tringle reliant les biellettes d'un côté des lames de manière à provoquer une translation de la tringle et par là une rotation des biellettes qui actionnent alors les lames.The present invention relates more particularly to a jalousie for which a control system acts simultaneously on all or part of the blades. The jalousie usually has a rectangular frame with two lateral uprights connected by two sleepers. The blades are integral with an axis whose ends are mounted in the lateral uprights (for horizontal blades) or in the sleepers (for vertical blades). Conventionally, the control of opening and closing of the blind, and thus the pivoting of the blades, is effected by a system with rod and links arranged on either side of the blades. Each blade carries at each of its ends a member called a driver and which is screwed to a connecting rod of the control system. A control handle then acts on a rod connecting the links on one side of the blades so as to cause a translation of the rod and thereby a rotation of the rods which then actuate the blades.

Dans les jalousies connues de ce type, le vissage de chaque biellette sur l'entraineur correspondant s'effectue dans l'axe des lames mobiles. De ce fait, lorsque le châssis est monté dans une baie, les vis ne peuvent plus être retirées et les lames ne peuvent donc pas être changées sans avoir à démonter toute la jalousie avec son châssis.In the known jalousies of this type, the screwing of each rod on the corresponding trainer takes place in the axis of the movable blades. Therefore, when the chassis is mounted in a bay, the screws can not be removed and the blades can not be changed without having to disassemble the entire blind with its chassis.

Un autre inconvénient de ce type de montage est qu'il est long à mettre en oeuvre et de ce fait son prix de revient est élevé.Another disadvantage of this type of assembly is that it is long to put implemented and therefore its cost price is high.

La structure décrite avec une tringle mobile en translation qui commande le mouvement des biellettes afin d'induire un mouvement des lames est en outre difficilement motorisable. Pour pallier cet inconvénient, il est connu d'équiper chaque extrémité de lame, du côté du système de commande, d'une roue dentée, ou tout du moins d'une portion de roue dentée. La denture correspondante est par exemple rendue solidaire de l'entraineur par concordance de forme et par vissage et vient par ailleurs en prise avec une vis sans fin. La vis sans fin peut être entrainée par une tige couplée à un moteur. Pour une jalousie, on peut prévoir des vis sans fin creuses. La tige couplée à un moteur peut alors passer à l'intérieur de chaque vis sans fin. Le moteur associé commande alors simultanément la rotation de l'ensemble des lames de la jalousie. Les documents DE 102 61 165 A1 et WO 2008/049150 A1 montrent des systèmes de commande pour lames de jalousies selon l'état de la technique.The structure described with a rod movable in translation which controls the movement of the rods to induce movement of the blades is also difficult to motorize. To overcome this drawback, it is known to equip each blade end, on the side of the control system, a toothed wheel, or at least a gear portion. The corresponding toothing is for example made integral with the trainer by matching shape and by screwing and also engages with a worm. The worm can be driven by a rod coupled to a motor. For a jealousy, we can provide hollow augers. The rod coupled to a motor can then pass inside each worm. The associated motor then simultaneously controls the rotation of all the blades of the blind. The documents DE 102 61 165 A1 and WO 2008/049150 A1 show control systems for jalousie blades according to the state of the art.

Le système évoqué au paragraphe précédent permet certes une motorisation d'une jalousie mais est également long et couteux à mettre en oeuvre et ne permet pas le changement d'une lame sans avoir à démonter toute la jalousie avec son châssis hors de la baie correspondante.The system mentioned in the preceding paragraph certainly allows a motorization of a blind but is also long and expensive to implement and does not allow the change of a blade without having to disassemble the entire blind with its chassis out of the corresponding bay.

La présente invention a alors pour but de fournir un système de commande de lames de jalousie permettant de réaliser un démontage d'une lame sans avoir à démonter toute la jalousie hors de la baie dans laquelle elle est intégrée.The present invention therefore aims to provide a control system blades jealousy to perform disassembly of a blade without having to disassemble all the jalousie out of the bay in which it is integrated.

De préférence, le système proposé sera d'un prix de revient moindre par rapport aux systèmes comparables déjà connus et/ou sera plus rapide à intégrer dans une menuiserie.Preferably, the proposed system will cost less compared to comparable systems already known and / or will be faster to integrate into a carpentry.

À cet effet la présente invention propose un système de commande pour lames de jalousies comportant : - un profilé s'étendant selon une direction longitudinale, - un entraineur s'étendant transversalement par rapport au profilé au travers d'une première face dudit profilé, - un boitier de liaison avec deux parois latérales s'étendant longitudinalement et perpendiculairement à l'entraineur, boitier à l'intérieur duquel se trouvent un secteur denté en prise avec une vis sans fin, le secteur denté étant associé à un axe traversant une paroi latérale et ledit axe étant relié à l'entraineur de manière à pouvoir l'entrainer en rotation.To this end, the present invention proposes a control system for jalousie blades comprising: - a profile extending in a longitudinal direction, - a trainer extending transversely relative to the profile through a first face of said section, - a connecting box with two lateral walls extending longitudinally and perpendicularly to the coach, box inside which is find a toothed sector meshing with a worm, the toothed sector being associated with an axis passing through a side wall and said axis being connected to the coach so that it can be rotated.

Selon la présente invention, le profilé présente une face au moins partiellement ouverte s'étendant perpendiculairement à la première face du profilé ; l'entraineur présente une extrémité présentant deux faces parallèles perpendiculaires à la première face du profilé, et l'axe associé au secteur denté présente une extrémité en forme d'étrier avec deux branches parallèles dont l'écartement correspond sensiblement à la distance séparant les deux faces parallèles de l'extrémité de l'entraineur.According to the present invention, the profile has an at least partially open face extending perpendicular to the first face of the profile; the driver has an end having two parallel faces perpendicular to the first face of the profile, and the axis associated with the toothed sector has a stirrup-shaped end with two parallel branches whose spacing substantially corresponds to the distance separating the two parallel faces of the end of the trainer.

L'invention propose ainsi des moyens permettant de venir monter le boitier de liaison dans le profilé en faisant coulisser une extrémité de l'axe sur une extrémité de l'entraineur. Le mouvement pour réaliser la connexion de l'axe traversant et plus généralement du boitier de liaison sur l'entraineur se fait dans un plan transversal par rapport à l'axe de rotation de la lame et ne demande donc pas de dégagement latéral. En outre, grâce à la face au moins partiellement ouverte du profilé, le montage et le démontage d'un, ou des, boitier(s) de liaison peuvent donc se faire même lorsqu'un châssis dans lequel est monté un système de commande selon la présente invention est scellé dans une baie.The invention thus provides means for mounting the connecting box in the profile by sliding one end of the axis on one end of the trainer. The movement to make the connection of the through shaft and more generally of the connecting box on the trainer is in a plane transverse to the axis of rotation of the blade and therefore does not require lateral clearance. In addition, thanks to the at least partially open face of the profile, the assembly and disassembly of one or the connection box (s) can therefore be done even when a chassis in which is mounted a control system according to the present invention is sealed in a bay.

Pour faciliter l'accès aux boitiers de liaison d'un système de commande selon la présente invention, on prévoit avantageusement que la face du profilé au moins partiellement ouverte est entièrement ouverte, et que le système de commande comporte en outre un couvercle permettant la fermeture de cette face entièrement ouverte.To facilitate access to the connection boxes of a control system according to the present invention, it is advantageously provided that the face of the at least partially open profile is completely open, and that the control system further comprises a lid for closing of this completely open face.

Une forme de réalisation préférée prévoit que l'entraineur présente une extrémité profilée de section carrée. Une telle forme est déjà habituellement utilisée pour former l'extrémité d'un entraineur. Elle permet, d'une part, de bien positionner l'axe traversant par rapport à l'entraineur et, d'autre part, une bonne liaison entre l'axe traversant et l'entraineur.A preferred embodiment provides that the trainer has a profiled end of square section. Such a shape is already commonly used to form the end of a trainer. It allows, on the one hand, to properly position the traversing axis relative to the trainer and, on the other hand, a good connection between the traversing axle and the trainer.

Pour assurer un bon maintien d'un boitier de liaison dans le profilé correspondant, il est proposé que le profilé comporte une première rainure longitudinale ouverte en direction de la face au moins partiellement ouverte du profilé réalisée soit sur la première face du profilé, soit sur une face opposée à la première face du profilé, et que le boitier de liaison présente sur une paroi latérale une première patte dont la forme est adaptée pour pouvoir pénétrer dans la première rainure et dont la position est telle qu'il est possible d'avoir à la fois cette première patte introduite dans la première rainure et l'entraineur en prise avec l'axe associé au secteur denté. Cette forme de réalisation permet d'éviter un déplacement transversal d'un boitier de liaison dans son profilé. Pour en outre empêcher tout risque de pivotement autour de l'axe longitudinal du profilé, le profilé comporte avantageusement en outre une seconde rainure longitudinale ouverte en direction de la face au moins partiellement ouverte du profilé sur la même face du profilé que la première rainure longitudinale et parallèle à celle-ci, et le boitier de liaison présente également de manière avantageuse, sur la paroi latérale portant la première patte, une seconde patte dont la forme est adaptée pour pouvoir pénétrer dans la seconde rainure et dont la position est telle qu'il est possible d'avoir à la fois cette seconde patte introduite dans la seconde rainure, la première patte introduite dans la première rainure et l'entraineur en prise avec l'axe associé au secteur denté.To ensure a good maintenance of a connecting box in the corresponding section, it is proposed that the profile has a first longitudinal groove open towards the at least partially open face of the section formed on the first face of the profile, or on a face opposite to the first face of the profile, and that the connecting box has a wall a first leg whose shape is adapted to be able to penetrate into the first groove and whose position is such that it is possible to have both this first tab introduced into the first groove and the trainer engaged with the first groove axis associated with the toothed sector. This embodiment avoids transverse displacement of a connecting box in its profile. To further prevent any risk of pivoting about the longitudinal axis of the profile, the profile advantageously further comprises a second longitudinal groove open towards the at least partially open face of the profile on the same face of the profile as the first longitudinal groove and parallel thereto, and the connecting box also advantageously has on the side wall carrying the first tab a second tab whose shape is adapted to be able to penetrate into the second groove and whose position is such that it is possible to have both this second lug introduced into the second groove, the first lug introduced into the first groove and the driver engaged with the axis associated with the toothed sector.

Dans les formes de réalisation évoquées au paragraphe précédent, la première patte et/ou la seconde patte peut être formée par le bord latéral d'une rainure s'étendant sur sensiblement toute la hauteur de la paroi latérale correspondante du boitier de liaison, ladite rainure étant ouverte vers la première rainure et/ou la seconde rainure du profilé.In the embodiments mentioned in the preceding paragraph, the first tab and / or the second tab may be formed by the lateral edge of a groove extending over substantially the entire height of the corresponding side wall of the connecting box, said groove being open towards the first groove and / or the second groove of the profile.

Pour permettre un montage d'un même boitier de liaison tant à une première extrémité d'une lame qu'à son extrémité opposée, les deux parois latérales du boitier de liaison sont avantageusement symétriques par rapport à un plan médian du boitier de liaison.To allow mounting of the same connection box both at a first end of a blade at its opposite end, the two side walls of the connecting box are preferably symmetrical with respect to a median plane of the connecting box.

Une forme de réalisation particulièrement avantageuse d'un système de commande selon l'invention prévoit que ce système comporte plusieurs boitiers de liaison avec à chaque fois une vis sans fin présentant un alésage longitudinal intérieur et un filetage extérieur, ainsi qu'en outre une tige de liaison passant à travers plusieurs alésages de vis sans fin, la tige et les alésages étant configurés de manière à ce que la tige de liaison puisse entrainer en rotation lesdites vis sans fin ; que la tige de liaison est réalisée en plusieurs tronçons, un tronçon correspondant à chaque fois à une vis sans fin ; que chaque tronçon peut coulisser longitudinalement par rapport aux alésages des vis sans fin, et qu'au moins une butée est prévue sur un tronçon de manière à permettre de limiter le coulissement dudit tronçon par rapport à l'alésage longitudinal intérieur de la vis sans fin correspondante. Alors que les dispositifs connus de l'art antérieur proposent uniquement des tiges de liaison d'une seule pièce imposant le montage de tous les boitiers de liaison quasi simultanément, la variante proposée permet de monter et démonter chaque boitier de liaison indépendamment des autres boitiers de liaison.A particularly advantageous embodiment of a control system according to the invention provides that this system comprises several connection boxes with each time a worm having an inner longitudinal bore and an external thread, and in addition a rod linkage passing through a plurality of worm bores, the shank and the bores being configured so that the connecting rod can rotate said worm; that the connecting rod is made of several sections, a section corresponding in each case to a worm; that each section can slide longitudinally with respect to the bores endless screws, and that at least one stop is provided on a section so as to limit the sliding of said section relative to the inner longitudinal bore of the corresponding worm. While the known devices of the prior art only propose connecting rods in one piece requiring the mounting of all the connection boxes almost simultaneously, the proposed variant allows to mount and dismount each connection box independently of the other boxes of link.

La présente invention concerne également une jalousie comportant :

  • un châssis avec deux montants profilés latéraux et deux traverses, et
  • des lames montées pivotantes entre les deux montants profilés latéraux,
caractérisée en ce qu'elle comporte en outre un système de commande tel que décrit plus haut.The present invention also relates to a jalousie comprising:
  • a frame with two lateral profile posts and two cross members, and
  • blades pivotally mounted between the two lateral profile posts,
characterized in that it further comprises a control system as described above.

Dans une telle jalousie chaque vis sans fin du système de commande est de préférence une pièce tubulaire ; toutes les vis sans fin disposées d'un même côté des lames sont alignées et reliées entre elles par une tige, d'un seul tenant ou de préférence en plusieurs tronçons, traversant toutes les vis sans fin, et la tige est reliée à un moteur.In such a jalousie each endless screw of the control system is preferably a tubular piece; all the worms arranged on the same side of the blades are aligned and connected together by a rod, in one piece or preferably in several sections, passing through all the worm, and the rod is connected to an engine .

Les figures 1 et 2 illustrent une jalousie selon la présente invention. De manière classique, une telle jalousie comporte deux montants latéraux 2, une traverse inférieure 4, une traverse supérieure 6 et des lames 8 montées pivotantes entre les montants latéraux 2. Sur les deux figures 1 et 2, les lames 8 sont illustrées dans une même position intermédiaire entre une position dite position fermée dans laquelle toutes les lames 8 seraient coplanaires correspondant à une position fermée de la jalousie et une position dite position ouverte dans laquelle toutes les lames 8 seraient pivotées d'environ 90° par rapport à la position fermée.The figures 1 and 2 illustrate a jealousy according to the present invention. Conventionally, such a jalousie comprises two lateral uprights 2, a lower crossbar 4, an upper crossbar 6 and blades 8 pivotally mounted between the lateral uprights 2. On both figures 1 and 2 , the blades 8 are illustrated in the same intermediate position between a position called closed position in which all the blades 8 would be coplanar corresponding to a closed position of the blind and a position called open position in which all the blades 8 would be rotated about 90 ° from the closed position.

Chaque montant latéral 2 comporte un profilé 10 en U et un couvercle 12 destiné à venir fermer le profilé 10 en reliant les extrémités libres des branches du U du profilé 10. Sur la figure 2, un profilé 10 n'a pas été illustré de manière à laisser apparaître un système de commande pour les lames 8 destiné à commander le passage de ces lames de la position ouverte vers la position fermée, ou inversement.Each lateral upright 2 comprises a U-shaped section 10 and a cover 12 intended to close the profile 10 by connecting the free ends of the branches of the U of the profile 10. On the figure 2 a profile 10 has not been illustrated so as to show a control system for the blades 8 for controlling the passage of these blades from the open position to the closed position, or vice versa.

Les figures 2 et 3 montrent la présence d'un boitier de liaison 14 monté à une extrémité de chaque lame 8. Des moyens décrits plus loin permettent de relier entre eux les boitiers de liaison 14. Ces moyens sont par exemple entrainés par un moteur (non représenté) pouvant prendre place dans une traverse, ou un montant latéral.The figures 2 and 3 show the presence of a connecting box 14 mounted at one end of each blade 8. Means described below allow to connect the connecting boxes 14. These means are for example driven by a motor (not shown) that can take place in a cross, or a side jamb.

La figure 4 illustre en perspective et à échelle agrandie un boitier de liaison 14. Un tel boitier comporte une enveloppe extérieure et des éléments disposés entièrement ou partiellement à l'intérieur de l'enveloppe extérieure.The figure 4 illustrates in perspective and on a larger scale a box of link 14. Such a housing comprises an outer casing and elements arranged wholly or partially inside the outer casing.

L'enveloppe extérieure du boitier de liaison 14 illustré ici comporte deux demi-coques assemblées par des vis (non représentées) et un clip de fixation 16. La forme globale de l'enveloppe extérieure est parallélépipédique avec deux faces latérales principales. Une première demi-coque porte une première face latérale 18 tandis qu'une seconde demi-coque porte une seconde face latérale 20 qui s'étend parallèlement à la première face latérale 18 et lui est sensiblement symétrique. Les deux demi-coques sont maintenues entre elles par des vis et le clip de fixation 16 permet de parfaire le maintien des deux demi-coques. Il s'agit d'une pièce en matière synthétique profilée en U avec deux branches élastiques qui vient pincer entre ses deux branches un côté des deux demi-coques lorsque celles-ci sont assemblées.The outer casing of the connecting box 14 illustrated here comprises two half-shells assembled by screws (not shown) and a fastening clip 16. The overall shape of the outer casing is parallelepiped with two main lateral faces. A first half-shell carries a first side face 18 while a second half-shell carries a second side face 20 which extends parallel to the first side face 18 and is substantially symmetrical. The two half-shells are held together by screws and the fastening clip 16 allows to perfect the maintenance of the two half-shells. It is a piece of U-shaped synthetic material with two elastic branches that pinches between its two branches one side of the two half-shells when they are assembled.

La première face latérale 18 porte une première rainure 22 longitudinale ainsi qu'une seconde rainure 24 longitudinale. La seconde face latérale 20 porte elle aussi une première rainure 22 longitudinale et une seconde rainure 24 longitudinale. Ces rainures étant disposées symétriquement et présentant sensiblement les mêmes formes, la même référence 22 est utilisée pour désigner les deux premières rainures et la même référence 24 est utilisée pour désigner les deux secondes rainures. Sur la figure 4, la première rainure 22 longitudinale de la première face latérale 18 n'apparaît pas car elle est légèrement raccourcie pour permettre le passage d'une vis d'assemblage des deux demi-coques de l'enveloppe extérieure du boitier de liaison 14.The first lateral face 18 carries a first longitudinal groove 22 and a second longitudinal groove 24. The second lateral face 20 also carries a first longitudinal groove 22 and a second longitudinal groove 24. These grooves being arranged symmetrically and having substantially the same shapes, the same reference 22 is used to designate the first two grooves and the same reference 24 is used to designate the two second grooves. On the figure 4 , the first longitudinal groove 22 of the first side face 18 does not appear because it is slightly shortened to allow the passage of an assembly screw of the two half-shells of the outer casing of the connecting box 14.

Une vis sans fin 26 est disposée longitudinalement dans le boitier de liaison 14 et elle s'étend parallèlement à la première face latérale 18 et à la seconde face latérale 20 (et parallèlement aux rainures sur ces faces).A worm 26 is disposed longitudinally in the connecting housing 14 and extends parallel to the first side face 18 and the second side face 20 (and parallel to the grooves on these faces).

La vis sans fin 26 présente une forme tubulaire. Elle présente ici un trou longitudinal 38 de section carrée qui traverse la vis sans fin de part en part. Sur sa face extérieure, la vis sans fin 26 présente un filetage dans sa partie centrale et des paliers à ses deux extrémités. L'enveloppe extérieure du boitier de liaison 14 est conformée de manière à ce que la paroi de ladite enveloppe forme deux paliers pour recevoir les extrémités de la vis sans fin 26 et assurent le guidage de celle-ci en rotation.The worm 26 has a tubular shape. It presents here a longitudinal hole 38 of square section which passes through the endless screw from one side to the other. On its outer face, the worm 26 has a thread in its central part and bearings at both ends. The outer casing of the connecting box 14 is shaped so that the wall of said casing forms two bearings for receiving the ends of the worm 26 and guiding the latter in rotation.

Un axe transversal 28 traverse aussi bien la première face latérale 18 que la seconde face latérale 20. Cet axe transversal 28 est solidaire d'un secteur denté 30 en prise avec la vis sans fin 26 comme illustré sur la figure 5. L'homme du métier comprendra immédiatement que le secteur denté correspond sensiblement à la course en rotation d'une lame 8. Dans le cas présent, pour une lame 8 pouvant pivoter d'environ 90°, le secteur denté s'étend sur un peu plus de 90°.A transverse axis 28 traverses both the first lateral face 18 and the second lateral face 20. This transverse axis 28 is integral with a toothed sector 30 in engagement with the worm 26 as illustrated in FIG. figure 5 . Those skilled in the art will immediately understand that the toothed sector substantially corresponds to the rotating stroke of a blade 8. In this case, for a blade 8 that can pivot about 90 °, the toothed sector extends over a little more than 90 °.

On remarque sur la figure 5 que l'axe transversal 28 est précontraint. En effet, cet axe transversal 28 présente une came 32 sur laquelle vient en appui un bras 34 télescopique dont l'extrémité libre est adaptée à la forme de la came 32 pour venir en prise avec celle-ci. Le bras 34 télescopique est monté pivotant à son autre extrémité autour d'un axe 36. Un ressort non représenté, par exemple un ressort hélicoïdal, est monté autour du bras 34 qui exerce ainsi une contrainte de retour élastique sur l'axe transversal 28 par l'intermédiaire de la came 32.We notice on the figure 5 that the transverse axis 28 is prestressed. Indeed, this transverse axis 28 has a cam 32 on which bears a telescopic arm 34 whose free end is adapted to the shape of the cam 32 to engage therewith. The telescopic arm 34 is pivotally mounted at its other end about an axis 36. A not shown spring, for example a helical spring, is mounted around the arm 34 which thus exerts an elastic return stress on the transverse axis 28. through the cam 32.

Chaque extrémité de l'axe transversal 28 dépassant hors de l'enveloppe extérieure du boitier de liaison 14 présente une forme cylindrique circulaire au centre de laquelle un évidement carré est réalisé. En outre, un côté de ce carré est entièrement ouvert si bien que chaque extrémité de l'axe transversal 28 se présente sous la forme d'un étrier inscrit dans un cylindre circulaire et présentant trois faces internes : un fond 40 plan et deux ailes latérales 42 planes également et s'étendant perpendiculairement au fond 40.Each end of the transverse axis 28 protruding out of the outer casing of the connecting box 14 has a circular cylindrical shape in the center of which a square recess is formed. In addition, one side of this square is fully open so that each end of the transverse axis 28 is in the form of a stirrup inscribed in a circular cylinder and having three internal faces: a bottom 40 plane and two lateral wings 42 planes also and extending perpendicularly to the bottom 40.

L'axe transversal 28 représenté (par exemple sur les figures 4 à 7) présente en outre un bossage 44 à sa périphérie. Ce bossage 44 forme une butée destinée à coopérer avec une contre butée décrite plus loin.The transverse axis 28 shown (for example on the Figures 4 to 7 ) further has a boss 44 at its periphery. This boss 44 forms a stop intended to cooperate with an abutment described below.

Une extrémité de chaque axe transversal 28 est destinée à coopérer avec un entraineur 46 qui se présente globalement sous la forme d'une pièce cylindrique de section carrée. Une extrémité de l'entraineur 46 vient prendre place dans l'étrier ménagé à l'extrémité correspondante de l'axe transversal 28 tandis que son autre extrémité vient coopérer avec un axe portant la lame 8. Du côté de la lame 8, l'extrémité de l'entraineur 46 est fendue longitudinalement. Cette forme permet de réaliser une liaison avec un axe et plus généralement avec un ensemble formant lame de jalousie qui ne sera pas détaillée ici.One end of each transverse axis 28 is intended to cooperate with a driver 46 which is generally in the form of a cylindrical piece of square section. One end of the driver 46 takes place in the stirrup formed at the corresponding end of the transverse axis 28 while its other end cooperates with an axis carrying the blade 8. On the side of the blade 8, the end of the driver 46 is slotted longitudinally. This form makes it possible to make a connection with an axis and more generally with a set forming a blade of jealousy that will not be detailed here.

Du côté du boitier de liaison 14, on suppose ici que l'entraineur 46 présente une section carrée car c'est la forme la plus couramment rencontrée pour le montage de lames de jalousie. Toutefois, l'homme du métier comprendra de la description qui suit qu'il est possible d'utiliser d'autres formes qui présentent deux faces parallèles. L'entraineur peut ainsi par exemple présenter une extrémité cylindrique circulaire avec uniquement deux méplats opposés. On peut aussi prévoir des sections de forme polygonale. Il s'agira alors plutôt de sections hexagonales ou octogonales.On the side of the connecting box 14, it is assumed here that the trainer 46 has a square section because it is the most commonly encountered form for the assembly of jalousie blades. However, those skilled in the art will understand from the following description that it is possible to use other shapes that have two parallel faces. The trainer can for example have a circular cylindrical end with only two opposite flats. It is also possible to provide sections of polygonal shape. It will be more like hexagonal or octagonal sections.

Le boitier de liaison 14 étant disposé à l'intérieur du profilé 10 et la lame 8 étant à l'extérieur de ce profilé, l'entraineur 46 qui relie le boitier de liaison 14 à la lame 8 traverse donc une paroi de ce profilé. Un trou de passage est donc prévu dans le profilé 10 au niveau de chaque lame 8. Un palier d'entraineur 48 est prévu au niveau de chaque trou de passage pour le maintien et le guidage de l'entraineur 46 qui présente au niveau du palier d'entraineur 48 une zone de section circulaire.The connecting box 14 being disposed inside the profile 10 and the blade 8 being outside this profile, the trainer 46 which connects the connecting box 14 to the blade 8 thus crosses a wall of this profile. A passage hole is therefore provided in the profile 10 at each blade 8. A driver bearing 48 is provided at each passage hole for holding and guiding the driver 46 which has at the level of the bearing 48 is a circular section.

Les figures 6 et 7 montrent deux exemples de montage dans le profilé 10 d'un système de commande de la position des lames 8.The Figures 6 and 7 show two examples of mounting in the profile 10 of a control system of the position of the blades 8.

Sur la figure 6, le boitier de liaison 14 est positionné contre la paroi du profilé 10 se trouvant du côté des lames 8 (c'est-à-dire la paroi du profilé traversée par l'entraineur 46). Le profilé 10 présente sur cette paroi une première rainure longitudinale 52 destinée à coopérer avec la première rainure 22 correspondante du boitier de liaison 14 ainsi qu'une seconde rainure longitudinale 54 destinée à coopérer avec la seconde rainure 24 correspondante du boitier de liaison 14.On the figure 6 , the connecting box 14 is positioned against the wall of the profile 10 located on the side of the blades 8 (that is to say the wall of the section through which the driver 46). The profile 10 has on this wall a first longitudinal groove 52 intended to cooperate with the corresponding first groove 22 of the connecting box 14 and a second longitudinal groove 54 intended to cooperate with the corresponding second groove 24 of the connecting box 14.

La première rainure longitudinale 52 et la seconde rainure longitudinale 54 sont ouvertes vers la face ouverte du profilé 10 (et fermée par le couvercle 12).The first longitudinal groove 52 and the second longitudinal groove 54 are open towards the open face of the profile 10 (and closed by the cover 12).

Le montage du boitier de liaison 14 dans le profilé 10 est alors simple et facile. De manière habituelle, le système de commande des lames 8 d'une jalousie est monté après assemblage des lames 8 sur le châssis comportant les deux montants latéraux 2, la traverse inférieure 4 et la traverse supérieure 6. Les entraineurs 46 sont en place et dépassent à l'intérieur du profilé 10.The mounting of the connecting box 14 in the section 10 is then simple and easy. In the usual manner, the control system of the blades 8 of a louver is mounted after assembly of the blades 8 on the frame comprising the two lateral uprights 2, the lower crossbar 4 and the upper crossbar 6. The trainers 46 are in place and protrude inside the profile 10.

Pour le montage des boitiers de liaison 14, une première variante prévoit de monter tous les boitiers de liaison 14 sur une tige à section carrée qui vient passer à l'intérieur de chaque vis sans fin 26. De la sorte, il suffit par la suite d'agir sur la tige à section carrée pour commander simultanément toutes les lames 8.For the mounting of the connecting boxes 14, a first variant provides for mounting all the connecting housings 14 on a square section rod which passes inside each worm 26. In this way, it is sufficient thereafter to act on the square section rod to simultaneously control all the blades 8.

L'ensemble comportant la tige à section carrée et les boitiers de liaison 14 est alors introduit dans le profilé 10 de telle sorte que chaque première rainure 22 des boitiers de liaison 14 vienne coopérer avec la première rainure longitudinale 52 du profilé 10. Ici, le bord extérieur, c'est-à-dire éloigné de la face latérale du boitier de liaison, de la première rainure 22 vient s'introduire dans la première rainure longitudinale 52 du profilé. De même, chaque seconde rainure 24 vient coopérer avec la seconde rainure longitudinale 54 du profilé 10. Chaque boitier de liaison 14 est ainsi guidé longitudinalement en translation dans le profilé 10.The assembly comprising the square-section rod and the connecting housings 14 is then introduced into the profile 10 so that each first groove 22 of the connecting boxes 14 comes to cooperate with the first longitudinal groove 52 of the profile 10. Here, the outer edge, that is to say remote from the side face of the connecting box, the first groove 22 is introduced into the first longitudinal groove 52 of the profile. Similarly, each second groove 24 cooperates with the second longitudinal groove 54 of the profile 10. Each connecting box 14 is thus guided longitudinally in translation in the section 10.

Une autre variante de réalisation de montage, lorsque le châssis n'est pas encore monté dans une baie, peut consister à venir mettre d'abord les boitiers de liaison 14 en place sur les entraineurs 46 puis de les relier avec une tige de liaison passant par les trous longitudinaux 38 des vis sans fin 26. En effet, tant que la jalousie n'est pas en place dans une baie, le profilé 10 reste accessible par le haut et par le bas.Another variant of the mounting embodiment, when the chassis is not yet mounted in a rack, may consist in first putting the connecting boxes 14 in place on the drivers 46 and then connecting them with a connecting rod passing by the longitudinal holes 38 of the worm 26. Indeed, as the jalousie is not in place in a bay, the section 10 remains accessible from above and from below.

Pour permettre la mise en place aisée de l'ensemble (ou uniquement des boitiers de liaison) dans le profilé 10, il est prévu dans la conception de la jalousie que lorsque celle-ci est posée à plat sur un plan de travail (châssis et lames à l'horizontale) que les entraineurs 46 sont orientés de telle sorte que la section carrée débouchant dans le profilé présente deux faces s'étendant longitudinalement. Il ne reste donc qu'à veiller ensuite à un positionnement correct de l'étrier en extrémité des axes transversaux 28. Le bossage 44 peut être un repère pour faciliter le contrôle de la bonne orientation de l'axe transversal 28 d'un boitier de liaison 14. Ainsi, en faisant coulisser les boitiers de liaison 14 vers les entraineurs 46, les axes transversaux 28 vont automatiquement venir prendre place sur les entraineurs 46. De préférence, le déplacement des boitiers de liaison 14 vers les entraineurs 46 se fait dans le sens de la gravité. Ainsi, une fois en place, les boitiers de liaison 14 sont maintenus en position par gravité ainsi que par la coopération des rainures du profilé avec les rainures correspondantes des boitiers de liaison 14. Quand l'axe transversal 28 a pivoté de 90°, la première rainure 22 et la seconde rainure 24 de chaque boitier de liaison 14 peut alors sortir de la première rainure longitudinale 52 et de la seconde rainure longitudinale 54 respectivement. Pour éviter un tel mouvement transversal en direction du couvercle 12, le bossage 44 évoqué plus haut et réalisé sur l'axe transversal 28 de chaque boitier de liaison 14 vient alors coopérer avec la seconde rainure longitudinale 54 pour empêcher un tel mouvement et garantir ainsi un parfait guidage et maintien du système dans toutes les positions des lames 8.In order to allow easy assembly of the assembly (or only of the connecting boxes) in the section 10, it is envisaged in the design of the blind that when it is laid flat on a work surface (chassis and blades horizontally) that the drivers 46 are oriented so that the square section opening into the profile has two faces extending longitudinally. All that remains then is to ensure then a correct positioning of the stirrup end of the transverse axes 28. The boss 44 can be a reference to facilitate the control of the correct orientation of the transverse axis 28 of a box of link 14. Thus, by sliding the connecting boxes 14 to the trainers 46, the transverse axes 28 will automatically take place on the trainers 46. Preferably, the displacement of the connecting boxes 14 to the trainers 46 is in the sense of gravity. Thus, once in place, the connecting boxes 14 are held in position by gravity as well as by the cooperation of the grooves of the profile with the corresponding grooves of the connecting housings 14. When the transverse axis 28 has rotated 90 °, the first groove 22 and the second groove 24 of each connecting housing 14 can then out of the first longitudinal groove 52 and the second longitudinal groove 54 respectively. To avoid such a transverse movement towards the cover 12, the boss 44 mentioned above and made on the transverse axis 28 of each connecting box 14 then cooperates with the second longitudinal groove 54 to prevent such movement and thus guarantee a perfect guidance and maintenance of the system in all the positions of the blades 8.

Le montage illustré sur la figure 7 n'est pas décrit dans le détail. Il est proposé ici de venir monter les boitiers de liaison 14 non pas sur la paroi du profilé 10 se trouvant du côté des lames 8 mais sur la paroi opposée. C'est alors sur cette paroi opposée que se trouvent alors la première rainure longitudinale 52 et la seconde rainure longitudinale 54 du profilé 10. Dans cette configuration, il convient d'adapter la longueur de l'entraineur 46. Pour mieux maintenir ce dernier, on peut alors aussi prévoir un clip de maintien 56 sur l'entraineur 46 entre la paroi du profilé 10 traversée par l'entraineur 46 et le boitier de liaison 14.The montage illustrated on the figure 7 is not described in detail. It is proposed here to mount the connecting boxes 14 not on the wall of the profile 10 located on the side of the blades 8 but on the opposite wall. It is then on this opposite wall that then lie the first longitudinal groove 52 and the second longitudinal groove 54 of the profile 10. In this configuration, it is appropriate to adapt the length of the trainer 46. To better maintain the latter, it is then also possible to provide a holding clip 56 on the drive 46 between the wall of the profile 10 traversed by the trainer 46 and the connecting box 14.

Les figures 8 et 9 illustrent une forme de réalisation préférée dans laquelle il n'y a pas une tige de liaison d'une seule pièce pour relier les boitiers de liaison 14 mais autant de tronçons 58 de tige que de boitiers de liaison 14.The figures 8 and 9 illustrate a preferred embodiment in which there is not an integral connecting rod for connecting the connecting housings 14 but as many rod sections 58 as linking boxes 14.

Chaque tronçon 58 de tige de liaison se présente sous la forme d'une pièce longitudinale à section carrée adaptée à l'intérieur des vis sans fin 26 avec un collet 60 placé à une position intermédiaire sur le tronçon 58.Each connecting rod section 58 is in the form of a longitudinal piece with a square section fitted inside the worm 26 with a collar 60 placed at an intermediate position on the section 58.

La figure 8 montre deux tronçons 58 de tige voisins dans une position permettant la liaison entre eux des boitiers de liaison. Pour bien montrer ces tronçons, la figure 8 ne montre pas une enveloppe extérieure d'un boitier de liaison, ni la vis sans fin correspondante. On aperçoit alors que deux tronçons 58 voisins se rejoignent face au secteur denté 30, c'est-à-dire à l'intérieur de la vis sans fin qui n'a pas été représentée pour permettre de voir la zone de jonction.The figure 8 shows two sections 58 of adjacent rods in a position for the connection between them connecting boxes. To show these sections well, the figure 8 does not show an outer casing of a connecting box, nor the corresponding worm. It can then be seen that two neighboring sections 58 meet opposite the toothed sector 30, that is to say inside the worm which has not been shown to allow the junction zone to be seen.

On suppose ici que les tronçons 58 sont disposés verticalement, c'est-à-dire que les boitiers de liaison 14 sont disposés les uns au-dessus des autres. Par effet de gravité, les tronçons 58 ont donc tendance à tomber vers le bas. Pour maintenir les tronçons 58 dans la position montrée, une entretoise 62 est disposée entre le boitier de liaison 14 inférieur et le collet 60 du premier tronçon 58 (en partant du bas), et plus précisément entre la vis sans fin 26 du boitier de liaison 14 inférieur et le collet 60 précité. Lorsque l'entretoise 62 est positionnée, tous les tronçons 58 sont alors positionnés.It is assumed here that the sections 58 are arranged vertically, that is to say that the connecting boxes 14 are arranged one above the other. By gravity effect, the sections 58 therefore tend to fall down. To maintain the sections 58 in the position shown, a spacer 62 is disposed between the lower connecting box 14 and the collar 60 of the first section 58 (starting from the bottom), and more precisely between the worm 26 of the connection box. 14 and the collar 60 mentioned above. When the spacer 62 is positioned, all the sections 58 are then positioned.

Au cas où la jalousie devait être disposée non pas verticalement ou inclinée mais horizontalement, on pourrait alors prévoir deux entretoises 62, une à chaque extrémité de la tige formée par les tronçons 58 de tige. On pourrait aussi prévoir une entretoise 62 par tronçon 58 mais cela n'a pas de réel intérêt.In case the jalousie should be arranged not vertically or inclined but horizontally, then two spacers 62 could be provided, one at each end of the rod formed by the rod sections 58. One could also provide a spacer 62 by section 58 but this has no real interest.

Comme illustré sur les figures 11 et 12 notamment, l'entretoise 62 est une pièce profilée en C destinée à venir enserrer une portion de section carrée d'un tronçon 58 de tige de liaison.As illustrated on Figures 11 and 12 in particular, the spacer 62 is a C-shaped piece designed to grip a portion of square section of a connecting rod section 58.

La figure 9 illustre le retrait de l'entretoise 62 illustrée sur la figure 8. Lorsque l'entretoise 62 est retirée, le tronçon 58 de tige de liaison peut alors coulisser vers le bas. Son mouvement vers le bas est bloqué lorsque le collet 60 du tronçon vient au contact de la vis sans fin 26 du boitier de liaison 14 inférieur. L'autre tronçon 58 de la figure 9 n'a pas été déplacé par rapport à sa position de la figure 8 mais il est clair que par gravité, une fois l'entretoise 62 retirée, tous les tronçons 58 coulissent vers le bas jusqu'à ce que leurs collets 60 viennent en butée. Si les axes transversaux 28 et les entraineurs 46 sont alors positionnés dans leur position de montage décrite plus haut (étrier avec ses ailes latérales orientées longitudinalement), un démontage de chaque boitier de liaison est alors possible en réalisant un premier mouvement de translation vers le haut pour dégager l'axe transversal 28 de l'entraineur 46 puis un second mouvement de translation pour retirer le boitier de liaison 14 hors de son profilé 10.The figure 9 illustrates the removal of the spacer 62 illustrated on the figure 8 . When the spacer 62 is withdrawn, the connecting rod section 58 can then slide downwards. Its downward movement is blocked when the collar 60 of the section comes into contact with the worm 26 of the lower connecting box 14. The other section 58 of the figure 9 was not moved in relation to his position from the figure 8 but it is clear that by gravity, once the spacer 62 removed, all sections 58 slide down until their collars 60 abut. If the transverse axes 28 and the drivers 46 are then positioned in their mounting position described above (stirrup with its longitudinally oriented lateral wings), disassembly of each connection box is then possible by performing a first translational movement upwards to clear the transverse axis 28 of the driver 46 and a second translational movement to remove the connecting box 14 from its profile 10.

Comme on peut le remarquer, le montage et le démontage du système de commande des lames de la jalousie est facile et rapide à réaliser.As can be seen, the assembly and disassembly of the control system of the blades of the blind is easy and quick to achieve.

La solution proposée permet donc à la fois un gain de temps lors du montage du système de commande et autorise une intervention sur ce système de commande aisée même lorsque la jalousie correspondante est scellée dans une baie.The proposed solution therefore saves time during the mounting of the control system and allows intervention on this easy control system even when the corresponding jalousie is sealed in a bay.

Le fait de prévoir des rainures sur deux faces opposées d'un boitier de liaison permet de n'avoir qu'un seul type de boitier qui peut alors être monté aussi bien dans un montant latéral ou dans l'autre montant latéral d'un châssis de jalousie, en fonction notamment de diverses contraintes.The fact of providing grooves on two opposite faces of a connecting box makes it possible to have only one type of case which can then be mounted as well in a lateral upright or in the other lateral upright of a frame of jealousy, depending in particular on various constraints.

La réalisation d'une tige en plusieurs tronçons permet d'intervenir sur une seule lame d'une jalousie et de démonter juste un seul boitier de liaison pour y accéder.The realization of a rod in several sections allows to intervene on a single blade of a jalousie and dismount just a single connection box to access it.

La solution proposée ici permet une grande modularité. Les boitiers de liaison peuvent correspondre à plusieurs types d'entraineur à partir du moment où ces entraineurs ont une même section carrée terminale. Le fait d'avoir des tronçons de tige de liaison permet aussi d'adapter le nombre de lames sur une jalousie en utilisant les mêmes tronçons de lames, seul le nombre de tronçons utilisés varie.The solution proposed here allows a great modularity. Binding boxes can correspond to several types of coach from the moment these coaches have the same terminal square section. The fact of having sections of connecting rod also makes it possible to adapt the number of blades on a blind with the same sections of blades, only the number of sections used varies.

Bien entendu, la présente invention ne se limite pas à la forme de réalisation préférée décrite ci-dessus et illustrée sur le dessin annexé. Elle concerne également toutes les variantes de réalisation à la portée de l'homme du métier dans le cadre des revendications ci-après.Of course, the present invention is not limited to the preferred embodiment described above and illustrated in the accompanying drawing. It also relates to all the variants within the scope of those skilled in the art within the scope of the claims below.
