Dispositif de connexion pour barres de stores  Connection device for blind bars

The invention further relates to a computer file comprising data for controlling a 3D printer to produce a device according to
l'invention. the invention.
Etat de la technique State of the art
[0002] On connaît des raccords pour coupler des barres de stores comprenant un ou deux anneaux munis d'une ouverture interne de section circulaire et de vis de serrage radiales qui coulissent le long du raccord. L'utilisateur emmanche les barres dans le raccord et serre les anneaux en vissant les vis de serrage à travers les anneaux et dans des trous taraudés à cet effet dans les barres. Le raccord vient en appui sur les barres ce qui solidarise l'ensemble raccord/barres. Cependant, l'utilisateur doit appliquer une force de serrage importante pour que les vis de serrage compriment le raccord sur les barres. De plus, la force de serrage est ponctuelle et limitée à la zone où la vis comprime le raccord ce qui ne permet pas d'obtenir un serrage uniforme et efficace sur la longueur du raccord. Par ailleurs, il est difficile de viser les trous taraudés dans la barre. Fittings are known for coupling blind bars comprising one or two rings provided with an internal opening of circular section and radial clamping screws which slide along the connection. The user slips the bars into the fitting and tightens the rings by screwing the clamping screws through the rings and into threaded holes for this purpose in the bars. The fitting bears on the bars which secures the connection / bar assembly. However, the user must apply a large clamping force for the clamping screws to compress the fitting on the bars. In addition, the clamping force is punctual and limited to the area where the screw compresses the connector which does not allow to obtain a uniform and effective clamping along the length of the connector. Moreover, it is difficult to target the tapped holes in the bar.
[0003] On connaît également des raccords comprenant une base sur laquelle deux mâchoires sont fixées. L'espacement entre une mâchoire et la base est contrôlé par une vis de serrage : l'utilisateur insère une barre entre chaque mâchoire et la base et visse la vis de serrage pour bloquer la barre entre la base et la mâchoire. Cependant ce type de raccord est volumineux par rapport aux barres de store ce qui complique son insertion dans un boitier de store. De plus, cette solution ne permet pas d'obtenir un serrage satisfaisant, notamment en torsion, lors du déroulement ou du relevage du store : par exemple, on peut observer une torsion de la base si la base n'a pas une rigidité suffisante ; le serrage n'est pas uniforme puisqu'il se fait par l'intermédiaire de deux mâchoires distinctes. Also known are connectors comprising a base on which two jaws are fixed. The spacing between a jaw and the base is controlled by a clamping screw: the user inserts a bar between each jaw and the base and screws the clamping screw to lock the bar between the base and the jaw. However this type of connection is bulky compared to the blind bars which complicates its insertion in a blind box. In addition, this solution does not provide a satisfactory tightening, especially in torsion, during unwinding or raising the awning: for example, one can observe a twist of the base if the base does not have sufficient rigidity; the tightening is not uniform since it is done by means of two separate jaws.
Bref résumé de l'invention Brief summary of the invention
[0004] Un but de la présente invention est de proposer un dispositif exempt ou qui minimise les inconvénients des solutions de l'art antérieur. An object of the present invention is to provide a device free or that minimizes the disadvantages of the solutions of the prior art.
[0005] Selon l'invention, ce but est atteint au moyen d'un dispositif destiné à la connexion de barres de stores, constitué par un tube muni d'une ouverture longitudinale de section non circulaire destinée à y insérer à chaque extrémité une dite barre ou un dit axe, un trou radial taraudé étant prévu à chaque extrémité du tube afin d'y visser des vis de maintien de ladite barre ou dudit axe. According to the invention, this object is achieved by means of a device for the connection of blind bars, consisting of a tube provided with a longitudinal opening of non-circular section intended to insert at each end a said bar or a said axis, a tapped radial hole being provided at each end of the tube to screw screws for holding said bar or said axis.
[0006] Cette solution présente notamment l'avantage par rapport à l'art antérieur de fournir un dispositif monobloc (en une seule pièce) pour connecter deux éléments (deux barres ou une barre et un axe de This solution has the advantage over the prior art of providing a monobloc device (in one piece) to connect two elements (two bars or a bar and an axis of
motorisation) ce qui facilite son utilisation lors du montage d'un store. motorisation) which facilitates its use when mounting a blind.
[0007] Le dispositif selon l'invention permet de connecter: The device according to the invention allows to connect:
- une barre et un axe de motorisation ; ou - une première barre et une deuxième barre. - a bar and a drive shaft; or - a first bar and a second bar.
[0008] Dans un mode de réalisation, l'ouverture présente un diamètre interne angle à angle compris entre 5 mm et 20 mm, de préférence entre 10 mm et 15 mm. La section de l'ouverture étant non circulaire, le terme angle à angle désigne le diamètre entre deux angles (ou arêtes) de l'ouverture, chaque angle étant formé par la jonction entre deux faces de l'ouverture. In one embodiment, the opening has an internal diameter angle between 5 mm and 20 mm, preferably between 10 mm and 15 mm. Since the section of the aperture is non-circular, the term angle angle refers to the diameter between two angles (or ridges) of the opening, each angle being formed by the junction between two faces of the opening.
[0009] Selon un mode de réalisation, le tube présente un diamètre externe compris entre 10 mm et 50 mm, de préférence entre 20 mm et 30 mm. According to one embodiment, the tube has an outer diameter of between 10 mm and 50 mm, preferably between 20 mm and 30 mm.
[0010] Dans un mode de réalisation, le tube présente une longueur comprise entre 20 mm et 1000 mm, de préférence entre 20 et 100 mm, préférentiellement entre 30 mm et 60 mm. In one embodiment, the tube has a length of between 20 mm and 1000 mm, preferably between 20 and 100 mm, preferably between 30 mm and 60 mm.
[0011] Selon un mode de réalisation, le tube présente une section externe non circulaire, de préférence polygonale. Ainsi, l'utilisateur peut bloquer le tube dans un outil adapté, par exemple une clé à molette, pendant l'installation du dispositif. According to one embodiment, the tube has a non-circular outer section, preferably polygonal. Thus, the user can block the tube in a suitable tool, for example a wrench, during installation of the device.
[0012] Dans un mode de réalisation, l'ouverture longitudinale présente une section polygonale, par exemple hexagonale. Dans un autre mode de réalisation, l'ouverture longitudinale présente une section en croissant. Ainsi, il est possible de choisir le dispositif dont l'ouverture a une section complémentaire à celle de la barre ou de l'axe de motorisation. Lorsque les sections sont complémentaires, la force de serrage, en particulier en torsion, entre la barre ou l'axe et le dispositif est en partie assurée par le contact bord à bord entre la barre et l'ouverture longitudinale. Ainsi, la force de serrage est en partie répartie toute la longueur du tube. In one embodiment, the longitudinal opening has a polygonal section, for example hexagonal. In another embodiment, the longitudinal opening has a crescent section. Thus, it is possible to choose the device whose opening has a section complementary to that of the bar or the drive shaft. When the sections are complementary, the clamping force, in particular in torsion, between the bar or the axis and the device is partly ensured by the edge-to-edge contact between the bar and the longitudinal opening. Thus, the clamping force is partly distributed throughout the length of the tube.
[0013] Selon un mode de réalisation, le tube présente sur au moins une portion de sa paroi externe au moins une nervure longitudinale et/ou une nervure transversale. Une nervure permet de renforcer la rigidité du dispositif, en particulier la rigidité en torsion. Le dispositif peut comprendre deux types de nervure: - au moins une nervure longitudinale orientée selon l'axe According to one embodiment, the tube has on at least a portion of its outer wall at least one longitudinal rib and / or a transverse rib. A rib makes it possible to reinforce the rigidity of the device, in particular the torsional stiffness. The device can comprise two types of rib: at least one longitudinal rib oriented along the axis
longitudinale du tube ; longitudinal tube;
- au moins une nervure transversale orientée perpendiculairement ou quasi perpendiculairement à l'axe longitudinal du tube. [0014] Selon un mode de réalisation, les pièces munies de nervures sont fabricables en injection plastique, par impression 3D (métal, bois, plastique, céramique, matière organique et le graphène), par usinage et/ou par injection sous pression (métal). Les pièces sans nervures sont fabricables en utilisant les procédés de l'art antérieur, comme l'injection plastique, par impression 3D (métal, plastique, céramique, matières organiques et le graphène), par impression additive ou soustractive, par usinage (toutes les matières mentionnées), par injection sous pression (métal) et par extrusion (métal et plastique). - At least one transverse rib oriented perpendicularly or substantially perpendicular to the longitudinal axis of the tube. According to one embodiment, the parts provided with ribs are manufacturable in plastic injection, by 3D printing (metal, wood, plastic, ceramic, organic material and graphene), by machining and / or by injection under pressure (metal ). The parts without ribs are manufacturable using the methods of the prior art, such as plastic injection, 3D printing (metal, plastic, ceramic, organic materials and graphene), additive or subtractive printing, machining (all mentioned materials), by injection under pressure (metal) and by extrusion (metal and plastic).
[0015] Les nervures apportent des améliorations techniques comme, le renfort des parois, une réduction de l'épaisseur des parois, une réduction du poids. Elles permettent de cibler le renforcement dans les zones du dispositif les plus exposées aux contraintes physiques, comme la force du moment (torsion), la pression... The ribs provide technical improvements such as reinforcement walls, a reduction in the thickness of the walls, a reduction in weight. They make it possible to target the reinforcement in the areas of the device most exposed to physical constraints, such as the force of the moment (torsion), the pressure ...
[0016] Les pièces sans nervures sont conçues de manière à ce que la paroi soit suffisamment épaisse pour résister aux contraintes exercées sur le dispositif de couplage. The parts without ribs are designed so that the wall is thick enough to withstand the stresses exerted on the coupling device.
[0017] Selon un mode de réalisation, ladite ouverture longitudinale est configurée pour que ladite barre ou ledit axe puisse adopter deux positions: une première position dans laquelle ledit axe ou ladite barre est libre en rotation et translation dans ladite ouverture longitudinale ; et - une deuxième position dans laquelle lesdites vis de maintien verrouillent la position dudit axe ou de ladite barre dans ladite ouverture. According to one embodiment, said longitudinal opening is configured so that said bar or said axis can adopt two positions: a first position in which said axis or said bar is free in rotation and translation in said longitudinal opening; and a second position in which said holding screws lock the position of said axis or of said bar in said opening.
[0018] Dans la première position, avantageusement l'utilisateur peut bouger la barre ou l'axe dans le dispositif, en rotation ou en translation, pour ajuster la position des barres ou des axes. Une fois que les barres ou les axes sont dans la position désirée, l'utilisateur visse les vis de maintien pour verrouiller la position des barres ou des axes dans le dispositif. Ce mode de réalisation facilite l'installation et le réglage du dispositif. [0019] Ce mode de réalisation permet d'éviter l'utilisation de lubrifiant. Dans les dispositifs existants, les lubrifiants sont utilisés pour pouvoir déplacer la barre ou l'axe dans le dispositif avant serrage. Cependant, l'utilisation de lubrifiant n'est pas avantageuse car les lubrifiants ont tendance à durcir après application, et à se transformer en colle. Ainsi, lors des réparations ou des réglages post installation, la barre ou l'axe est collé dans le dispositif ce qui rend très difficile, voire impossible, les opérations de réparation ou de réglage, par exemple pour modifier la distance d'engagement de l'axe ou de la barre dans le dispositif ou remplacer le dispositif. [0020] Selon un mode de réalisation, ledit axe ou ladite barre est libre en rotation sur une plage angulaire comprise entre 0 et 360 degrés, de préférence entre 0 et 180 degrés, en particulier entre 0 et 60 degrés. Par exemple, la plage angulaire de liberté dépend du profil de l'ouverture. Pour une ouverture de profil six pan ou hexagonal, la plage angulaire est par exemple de 60 degrés. Pour une ouverture de profil carré, la plage angulaire est de 90 degrés. Pour un profil triangulaire, la plage angulaire est de 120 degrés. In the first position, the user can advantageously move the bar or the axis in the device, in rotation or in translation, to adjust the position of the bars or axes. Once the bars or shafts are in the desired position, the user screws the retaining screws to lock the position of the bars or shafts in the device. This embodiment facilitates installation and adjustment of the device. This embodiment avoids the use of lubricant. In existing devices, the lubricants are used to move the bar or shaft into the device before tightening. However, the use of lubricant is not advantageous because the lubricants tend to harden after application, and to turn into glue. Thus, during repairs or post-installation adjustments, the bar or the axis is stuck in the device which makes it very difficult, if not impossible, repair or adjustment operations, for example to change the engagement distance of the device. axis or bar in the device or replace the device. According to one embodiment, said axis or said bar is free to rotate over an angular range between 0 and 360 degrees, preferably between 0 and 180 degrees, in particular between 0 and 60 degrees. For example, the angular range of freedom depends on the profile of the opening. For a profile opening six pan or hexagonal, the angular range is for example 60 degrees. For a square profile opening, the angular range is 90 degrees. For a triangular profile, the angular range is 120 degrees.
[0021] Dans un mode de réalisation, ledit tube comprend une paroi définie par une paroi externe et une paroi interne, la paroi interne délimitant l'ouverture longitudinale, ledit tube comprenant un logement aménagé dans une portion de la paroi interne opposée audit trou taraudé, ledit logement étant destiné à recevoir ladite barre ou dudit axe. In one embodiment, said tube comprises a wall defined by an outer wall and an inner wall, the inner wall defining the longitudinal opening, said tube comprising a housing. arranged in a portion of the inner wall opposite said tapped hole, said housing being adapted to receive said bar or said axis.
[0022] Dans ce mode de réalisation, la paroi interne de l'ouverture longitudinale comprend un logement. Le logement est de préférence aménagé selon l'axe longitudinal de l'ouverture et s'étend In this embodiment, the inner wall of the longitudinal opening comprises a housing. The housing is preferably arranged along the longitudinal axis of the opening and extends
préférentiellement sur toute la longueur de l'ouverture. La paroi de la barre ou de l'axe opposée au logement est appelée paroi de serrage. Lors du serrage des vis de maintien, la barre ou l'axe se déplace selon un axe perpendiculaire à l'axe longitudinal de l'ouverture, de façon à ce que la paroi de serrage vienne se loger dans le logement. preferably over the entire length of the opening. The wall of the bar or the axis opposite the housing is called the clamping wall. When tightening the retaining screws, the bar or the axis moves along an axis perpendicular to the longitudinal axis of the opening, so that the clamping wall is housed in the housing.
[0023] Avantageusement, dans ce mode de réalisation, le maintien de la barre ou de l'axe est assuré principalement voire exclusivement par le contact entre la paroi de serrage et le logement. La contribution au serrage des parois de la barre ou de l'axe autres que la paroi de serrage est négligeable, voire nulle. Advantageously, in this embodiment, the maintenance of the bar or the axis is provided mainly or exclusively by the contact between the clamping wall and the housing. The contribution to clamping the walls of the bar or the axis other than the clamping wall is negligible, or even zero.
[0024] De préférence, seule la paroi de serrage est en contact avec la paroi interne du tube lorsque la barre ou l'axe est maintenu dans le dispositif. Preferably, only the clamping wall is in contact with the inner wall of the tube when the bar or the axis is held in the device.
[0025] Dans un mode de réalisation, la paroi externe présente un ou plusieurs bords droits. Cela permet de bloquer le dispositif avec un outil lors de l'installation, autrement dit un serrage latéral, par exemple une clé à molette ou une clé plate. Cela permet aussi de stabiliser le dispositif sur le banc de travail lors de l'usinage. In one embodiment, the outer wall has one or more straight edges. This makes it possible to block the device with a tool during installation, in other words a lateral tightening, for example a wrench or a flat key. This also makes it possible to stabilize the device on the work bench during machining.
[0026] Dans un mode de réalisation, le logement a une forme In one embodiment, the housing has a shape
complémentaire à une paroi de ladite barre ou dudit axe. En particulier, le logement a une forme complémentaire à celle de la paroi de serrage de l'axe ou de la barre. [0027] Selon un mode de réalisation, ledit trou débouche sur une chambre aménagée dans la paroi et ouverte sur l'ouverture longitudinale, ledit dispositif comprenant un insert logé dans ladite chambre, ledit insert présentant un trou traversant taraudé. [0028] L'insert est un élément de serrage et/ou de renfort, et est solidaire du tube. complementary to a wall of said bar or said axis. In particular, the housing has a shape complementary to that of the clamping wall of the axis or the bar. According to one embodiment, said hole opens on a chamber formed in the wall and open on the longitudinal opening, said device comprising an insert housed in said chamber, said insert having a threaded through hole. The insert is a clamping element and / or reinforcement, and is integral with the tube.
[0029] L'insert permet une meilleure répartition de la force de serrage de la vis de maintien. Lors du serrage de la vis de maintien dans l'insert, la vis vient en appui sur la barre ou l'axe. En position serrée, l'insert est en appui sur la paroi du tube, et exerce une pression selon une direction opposée à la direction du déplacement de la vis dans le taraudage de l'insert. Sans l'insert, la force de serrage (couple de serrage) est répartie, quai exclusivement ou exclusivement, sur les filets du taraudage de l'insert et de la vis. Grâce à l'insert, la force de serrage est aussi distribuée sur la surface d'appui de l'insert sur la paroi. The insert allows a better distribution of the clamping force of the holding screw. When tightening the retaining screw in the insert, the screw bears on the bar or the axis. In the tight position, the insert bears on the wall of the tube, and exerts a pressure in a direction opposite to the direction of displacement of the screw in the tapping of the insert. Without the insert, the clamping force (tightening torque) is distributed exclusively or exclusively on the threads of the tapping of the insert and the screw. Thanks to the insert, the clamping force is also distributed on the bearing surface of the insert on the wall.
[0030] Lors du serrage, l'insert vient en appui sur la paroi du tube, ce qui définit une surface d'appui. La force de serrage entre la vis et la barre (ou l'axe) est répartie sur les filets de l'assemblage vis/taraudage et sur la surface d'appui de l'insert sur la paroi. Ainsi, grâce à l'insert, la force de serrage est répartie sur une plus grande surface qu'en absence d'insert. Cela permet de diminuer la force de serrage sur les filets de l'assemblage vis/taraudage. When tightening, the insert bears on the wall of the tube, which defines a bearing surface. The clamping force between the screw and the bar (or the axis) is distributed over the threads of the screw / tapping assembly and on the bearing surface of the insert on the wall. Thus, thanks to the insert, the clamping force is distributed over a larger area in the absence of insert. This reduces the clamping force on the threads of the screw / tapping assembly.
[0031] L'insert a une longueur supérieure à la largeur de l'ouverture longitudinale de façon à empêcher la rotation de l'insert dans l'ouverture longitudinale. The insert has a length greater than the width of the longitudinal opening so as to prevent rotation of the insert in the longitudinal opening.
[0032] Dans un mode de réalisation, la chambre de l'insert est opposée au logement destiné à recevoir la paroi de contact de la barre ou de l'axe. [0033] L'insert coopère avec le trou radial, par exemple l'insert est emmanché dans le trou radial. Alternativement, l'insert et le trou radial présente des moyens d'attaches complémentaires, par exemple de type gorge/ergot. Alternativement, l'insert présente une denture externe qui s'engrène dans une denture interne complémentaire du trou radial. In one embodiment, the chamber of the insert is opposite the housing for receiving the contact wall of the bar or the axis. The insert cooperates with the radial hole, for example the insert is fitted into the radial hole. Alternatively, the insert and the radial hole have complementary fastening means, for example of throat / lug type. Alternatively, the insert has an external toothing which meshes with an internal toothing complementary to the radial hole.
[0034] Dans un mode de réalisation, l'insert est taraudé. Le taraudage permet de visser les vis de maintien dans l'insert. In one embodiment, the insert is threaded. Tapping makes it possible to screw the retaining screws into the insert.
[0035] Dans un mode de réalisation, ledit insert comprend deux parties à savoir une base et une portion tubulaire, la portion tubulaire s'étendant depuis la base, le diamètre extérieur de la base étant supérieur au diamètre extérieur de la portion tubulaire, la portion tubulaire étant destinée à s'insérer dans le trou taraudé. La base est au moins partiellement dans la chambre, et présente un diamètre supérieur au diamètre du trou radial, ce qui empêche l'insert de sortir du trou lors du serrage de la vis dans l'insert. [0036] Selon un mode de réalisation, le tube comprend une fenêtre traversante débouchant sur l'ouverture longitudinale. De préférence, la fenêtre est positionnée entre les deux trous radiaux, par exemple à mi- distance. In one embodiment, said insert comprises two parts namely a base and a tubular portion, the tubular portion extending from the base, the outer diameter of the base being greater than the outer diameter of the tubular portion, the tubular portion being adapted to fit into the threaded hole. The base is at least partially in the chamber, and has a diameter greater than the diameter of the radial hole, which prevents the insert from coming out of the hole when tightening the screw in the insert. According to one embodiment, the tube comprises a through window opening on the longitudinal opening. Preferably, the window is positioned between the two radial holes, for example at mid-distance.
[0037] La fenêtre traversante permet de contrôler l'espacement entre les deux barres ou axes dans le dispositif. Il est important de laisser un espace entre les éléments dans le dispositif, entre deux barres ou deux axes ou entre un axe et une barre, pour permettre la dilatation thermique de ces derniers. The through window to control the spacing between the two bars or axes in the device. It is important to leave a space between the elements in the device, between two bars or two axes or between an axis and a bar, to allow the thermal expansion of the latter.
[0038] La fenêtre permet également de contrôler l'alignement des éléments, et de savoir s'ils sont dans le prolongement axial l'un de l'autre. The window also controls the alignment of the elements, and whether they are in the axial extension of one another.
[0039] La fenêtre permet également de connaître la distance The window also allows to know the distance
d'engagement d'un élément (barre ou axe) dans le dispositif. [0040] Selon un mode de réalisation, le tube présente une section externe non circulaire choisi parmi un profil polygonal par exemple carré ou triangulaire, six pans ou hexagonal, vis étoile. L'invention n'est pas limitée à ces profils, l'invention concerne tous types de profils. [0041] Dans un mode de réalisation, au moins un desdits trous radiaux est plus long que l'épaisseur minimale des parois. Cela permet d'augmenter le couple de serrage (ou la force de serrage) de la vis de maintien sur la barre ou l'axe de motorisation. engaging an element (bar or axis) in the device. According to one embodiment, the tube has a non-circular outer section selected from a polygonal profile, for example square or triangular, hexagon or hexagonal screw star. The invention is not limited to these profiles, the invention relates to all types of profiles. In one embodiment, at least one of said radial holes is longer than the minimum thickness of the walls. This makes it possible to increase the tightening torque (or the clamping force) of the retaining screw on the bar or the drive shaft.
[0042] Selon un mode de réalisation, lesdits trous sont positionnés à l'intersection d'une nervure longitudinale et d'une nervure transversale. According to one embodiment, said holes are positioned at the intersection of a longitudinal rib and a transverse rib.
[0043] Selon un mode de réalisation, le tube est formé de polyamide, de préférence du polyamide renforcé de fibre de verre. Par exemple, le polyamide renforcé de fibre de verre est choisi parmi PA66 GF 50 ou PA66 GF 30 : L'utilisation de polyamide, en particulier de polyamide renforcé de fibre de verre permet d'obtenir des dispositifs qui résistent à une According to one embodiment, the tube is formed of polyamide, preferably polyamide reinforced with fiberglass. For example, the glass-fiber-reinforced polyamide is chosen from PA66 GF 50 or PA66 GF 30: The use of polyamide, in particular glass-fiber-reinforced polyamide, makes it possible to obtain devices that are resistant to
température jusqu'à 250°C. Le dispositif peut ainsi mieux résister à la chaleur lorsqu'il est monté dans un boîtier de store exposé au soleil. temperature up to 250 ° C. The device can thus better withstand heat when mounted in a sun-blind housing.
[0044] Dans un mode de réalisation, le tube est en métal ou alliage métallique, par exemple en acier. [0045] Selon un mode de réalisation, le dispositif est formé par usinage. In one embodiment, the tube is made of metal or metal alloy, for example steel. According to one embodiment, the device is formed by machining.
[0046] Dans un mode de réalisation, le dispositif est formé par fabrication additive, par exemple par impression 3D. In one embodiment, the device is formed by additive manufacturing, for example by 3D printing.
[0047] L'invention concerne également un assemblage comprenant un dispositif selon l'invention connecté avec au moins une barre de store et/ou avec un axe de motorisation. [0048] Dans un mode de réalisation de l'assemblage, l'ouverture du tube à une section de dimensions complémentaires à la section de ladite barre ou ledit axe de motorisation. The invention also relates to an assembly comprising a device according to the invention connected with at least one blind bar and / or with a drive shaft. In one embodiment of the assembly, the opening of the tube to a section of dimensions complementary to the section of said bar or said axis of motorization.
