Description

Domaine techniqueTechnical area

La présente invention concerne un élément de connexion permettant de solidariser les cordonnets des lamelles orientables des stores vénitiens à leur dispositif d'entrainement.The present invention relates to a connection element making it possible to secure the cords of the adjustable slats of Venetian blinds to their drive device.

Etat de la techniqueState of the art

Les stores vénitiens, également désignés stores à lamelles orientables, comprennent des cordonnets fixés sur les bords avant et arrière des lamelles qui permettent leur inclinaison à partir d'un dispositif d'entrainement, généralement disposé dans la partie supérieur du store vénitien. Lors du montage des stores ou de leur pose, il convient de combiner les cordonnets aux cordelettes du dispositif d'entrainement. Un élément de connexion, souvent désigné par le terme de «sabot» permet une telle connexion des cordonnets et de leur cordelettes respectives.Venetian blinds, also referred to as adjustable slat blinds, comprise cords attached to the front and rear edges of the slats which allow their inclination from a drive device, generally arranged in the upper part of the Venetian blind. When mounting the blinds or installing them, the cords should be combined with the cords of the drive device. A connection element, often designated by the term "shoe" allows such connection of the cords and their respective cords.

Le document CH710907 décrit un exemple de tel élément de connexion, comportant une partie destinée à se fixer sur la cordelette et une autre partie propre à pincer un cordonnet. Cette seconde partie est une structure tubulaire dans laquelle le cordonnet est inséré par son extrémité. Cela implique que l'extrémité du cordonnet soit libre. Cela limite en outre l'automatisation du procédé de montage qui reste en grande partie manuel.The document CH710907 describes an example of such a connection element, comprising a part intended to be fixed on the cord and another part capable of pinching a cord. This second part is a tubular structure in which the cord is inserted by its end. This implies that the end of the cord is free. This also limits the automation of the assembly process which remains largely manual.

Le document CH714223 décrit un autre exemple de sabot comportant une base, destinées à se fixer sur les cordelettes, et un élément de serrage combiné au cordonnet. La base et l'élément de serrage sont deux pièces distinctes qui doivent ensuite être appariées pour rendre effectif la connexion des cordonnets avec leurs cordelettes respectives. Bien que le dispositif décrit dans ce document permette une automatisation au moins partielle du montage, il nécessite l'utilisation de plusieurs pièces distinctes et une étape d'appariement de ces pièces.The document CH714223 describes another example of a clog comprising a base, intended to be fixed on the cords, and a tightening element combined with the cord. The base and the clamping element are two separate parts which must then be paired to make the connection of the cords with their respective cords effective. Although the device described in this document allows automation at least partial assembly, it requires the use of several separate parts and a step of pairing these parts.

Les sabots existants sont en outre généralement adaptés à une largeur donnée de cordonnets, ce qui oblige à produire et à stocker plusieurs types de sabots. Il apparaît donc avantageux de pouvoir limiter la diversité des sabots et/ou de leurs dimensions.Existing clogs are also generally adapted to a given width of cords, which makes it necessary to produce and store several types of clogs. It therefore appears advantageous to be able to limit the diversity of the clogs and/or their dimensions.

Les stores vénitiens possèdent plusieurs cordonnets. Le montage des cordonnets et de leur sabot représente donc un temps et un coût associé non négligeable. Les éléments de connexion et procédés existants peuvent donc être avantageusement améliorés pour minimiser les coûts et les temps de production.Venetian blinds have multiple cords. The mounting of the cords and their sabot therefore represents a significant time and associated cost. Existing connection elements and methods can therefore be advantageously improved to minimize production costs and times.

Bref résumé de l'inventionBrief summary of the invention

Un but de la présente invention est de proposer un élément de connexion exempt des limitations évoquées ci-dessus. En particulier, un but de la présente invention est de proposer un élément de connexion adapté à un montage facile et automatisable. Un autre but de la présente invention est de limiter le nombre de pièces nécessaires à la connexion des cordonnets et de leur cordelette d'entrainement à une pièce unique ou un ensemble de pièces totalement intégrées. Un but supplémentaire est de proposer un élément de connexion facilement adaptable à plusieurs types de cordonnets, et qui ne soient en particulier pas limité par la largeur des cordonnets.An object of the present invention is to provide a connection element free of the limitations mentioned above. In particular, an object of the present invention is to provide a connection element suitable for easy and automatable assembly.

Un but supplémentaire est de proposer un store vénitien équipé d'éléments de connexion des cordonnets d'inclinaison à leurs cordelettes d'entrainement, dont un des bord reste libre.Another object of the present invention is to provide a Venetian blind whose cords, allowing the inclination of the slats, can be easily connected to the drive cords and/or adjusted. An additional object is to provide a Venetian blind equipped with elements for connecting the inclination cords to their drive cords, one of the edges of which remains free.

Un autre but de la présente invention est de proposer un procédé de montage des cordonnets d'inclinaison des lamelles des stores vénitiens, avec un élément de connexion, qui soit totalement automatisé.Another object of the present invention is to provide a method for mounting the inclination cords of the slats of Venetian blinds, with a connection element, which is totally automated.

Selon l'invention, ces buts sont atteints notamment au moyen de l'élément de connexion, au procédé associé et au store correspondant, tels que revendiqués dans les revendication indépendantes et détaillés dans les revendications qui en dépendent. En particulier, l'élément de connexion selon la présente invention est constitué d'une pièce unique, ou d'un ensemble de pièces totalement intégrées. L'élément de connexion comporte une fente latérale permettant d'insérer un cordonnet plat sur l'une de ses tranches et de laisser l'autre libre.According to the invention, these aims are achieved in particular by means of the connection element, the associated method and the corresponding blind, as claimed in the independent claims and detailed in the claims which depend thereon. In particular, the connection element according to the present invention consists of a single part, or of a set of fully integrated parts. The connection element comprises a lateral slot allowing a flat cord to be inserted on one of its edges and to leave the other free.

Cette solution présente notamment l'avantage par rapport à l'art antérieur de permettre une automatisation du procédé de montage. Il présente l'avantage supplémentaire de permettre l'appariement de l'élément de connexion avec des cordonnets de toute largeur. D'autres avantages apparaitront dans la description détaillée de l'invention ci-dessous.This solution has the particular advantage over the prior art of allowing automation of the mounting process. It has the additional advantage of allowing the connection element to be matched with cords of any width. Other advantages will appear in the detailed description of the invention below.

Exemple(s) de mode de réalisation de l'inventionExample(s) of embodiment of the invention

Un store à lamelles orientables S selon la présente description comprend plusieurs lamelles S1, S2, S3...Sn, superposées, chacune des lamelles comprenant un pivot P1, P2, P3..Pn à chacune de ses extrémités (figure 1). Les pivots P1, P2, P3..Pn sont adaptés pour maintenir les lamelles S1, S2, S3...Sn, dans des glissières latérales fixées sur l'encadrement des ouvertures (non représentées) tout en permettant leur pivotement selon leur axe longitudinal A. Les lamelles S1, S2, S3...Sn, peuvent être remontées ou descendues au moyens de bandes tractrices 2 fixées à une traverse inférieure (non représentée) sur laquelle elles peuvent s'empiler lors de l'ouverture du store. Les lamelles S1, S2, S3...Sn, comportent un espace adapté au passage de telles bandes tractrices 2 de sorte à en rester indépendantes. Des cordonnets 3, 3' sont fixés sur les bords longitudinaux opposés de chacune des lamelles S1, S2, S3...Sn, de sorte à pouvoir les faire pivoter sur leurs pivots respectifs P1, P2, P3..Pn selon leur axe de rotation longitudinal A ou axe de pivotement, dans un sens ou dans l'autre. Une lamelle S1 possède un bord postérieur BP1 et un bord frontal BF1, correspondant chacun aux deux chants opposés longitudinaux de la lamelle. Chacune des lamelles Sn possède un bord postérieur BPn et un bord frontal BFn. Au moins un premier cordonnet 3 est fixé sur l'ensemble des bords frontaux BFn des lamelles Sn. Au moins un second cordonnet 3' est fixé sur l'ensemble des bords postérieures BPn des lamelles Sn. De préférence, plusieurs premiers cordonnets 3 sont fixés sur les bords frontaux BFn et plusieurs seconds cordonnets 3' sont fixés sur les bords postérieurs BPn. Ils peuvent être par exemple disposés en vis-à-vis les uns des autres. Ils peuvent être disposés en vis-à-vis des bandes tractrices 2 servant à ouvrir et fermer le store à lamelle S. Le nombre et la disposition des cordonnets 3, 3' importe peu dans le cadre de la présente description. Généralement deux cordonnets 3 sont disposés sur les bords frontaux BFn et deux cordonnets 3' sont disposés sur les bords postérieurs BPn. A blind with adjustable slats S according to the present description comprises several slats S1, S2, S3...Sn, superimposed, each of the slats comprising a pivot P1, P2, P3...Pn at each of its ends ( figure 1 ). The pivots P1, P2, P3..Pn are adapted to hold the slats S1, S2, S3...Sn, in the side slides fixed to the frame of the openings (not shown) while allowing them to pivot along their longitudinal axis A. The slats S1, S2, S3...Sn can be raised or lowered by means of traction bands 2 fixed to a lower crosspiece (not shown) on which they can stack when the blind is opened. Slats S1, S2, S3...Sn include a space suitable for the passage of such traction strips 2 so as to remain independent of them. Cords 3, 3' are fixed on the opposite longitudinal edges of each of the slats S1, S2, S3...Sn, so as to be able to pivot them on their respective pivots P1, P2, P3...Pn according to their axis of longitudinal rotation A or pivot axis, in one direction or the other. An S1 slat has a posterior edge BP1 and a front edge BF1, each corresponding to the two opposite longitudinal edges of the slat. Each of the Sn lamellae has a posterior edge BPn and a front edge BFn. At least a first cord 3 is fixed on all of the front edges BFn of the slats Sn. At least one second cord 3' is attached to all of the posterior edges BPn of the slats Sn. Preferably, several first cords 3 are attached to the front edges BFn and several second cords 3' are attached to the rear edges BPn. They can for example be arranged facing each other. They can be arranged opposite the traction strips 2 used to open and close the slat blind S. The number and arrangement of the cords 3, 3' is of little importance in the context of the present description. Generally two cords 3 are arranged on the front edges BFn and two cords 3' are arranged on the rear edges BPn.

Les cordonnets 3, 3' sont de forme plate, c'est-à-dire qu'ils ont une épaisseur inférieure à leur largeur. Ils comportent sur leur tranche, à intervalles régulier, des boucles permettant de les solidariser avec chacune des lamelles S1, S2, S3...Sn. La tranche des cordonnets comportant les boucles est orientée vers les lamelles auxquelles ils sont fixées.The cords 3, 3' are flat in shape, that is to say they have a thickness less than their width. They comprise on their edge, at regular intervals, loops making it possible to secure them with each of the slats S1, S2, S3...Sn. The edge of the cords comprising the loops is oriented towards the slats to which they are attached.

La figure 2 montre un exemple de dispositif d'entrainement 5 permettant d'incliner les lamelles S1, S2, S3...Sn selon leur axe longitudinal A, de sorte à moduler leur effet d'ombrage. Il est entendu que lorsque les lamelles S1, S2, S3...Sn sont disposées horizontalement, elles laissent passer un maximum de lumière. Lorsqu'elles sont au contraire inclinées à leur maximum par rapport à un plan horizontal, elles occultent la lumière au maximum. Le dispositif d'entrainement 5 comporte selon cet exemple un axe d'entrainement (non représenté) orienté parallèlement à l'axe A de pivotement des lamelles. Des cordelettes 6, 6' en lien avec cet axe d'entrainement sont disposées par paires de part et d'autre de l'axe d'entrainement du dispositif d'entrainement 5 de sorte à être réciproquement entrainées vers le haut ou vers le bas lors de la rotation de l'axe d'entrainement. En d'autres termes, une cordelette 6 d'une paire de cordelettes 6, 6' est abaissée quand l'autre cordelette 6' de cette même paire est tractée vers le haut et inversement. Chacune des cordelettes 6, 6' comporte à son extrémité, ou à proximité de son extrémité, un dispositif d'accroche 61. Le dispositif d'accroche 61 est généralement une boule mais il peut prendre la forme de tout élément ayant une dimension transversale supérieure au diamètre de la cordelette correspondante. Il peut être à cet effet sous la forme d'un axe transversal. Plusieurs paires de cordelettes 6, 6' sont disposées le long de l'axe d'entrainement. Le nombre de cordelettes 6, 6' correspond au nombre de cordonnets 3, 3'. There picture 2 shows an example of a drive device 5 allowing the slats S1, S2, S3...Sn to be tilted along their longitudinal axis A, so as to modulate their shading effect. It is understood that when the slats S1, S2, S3...Sn are arranged horizontally, they allow a maximum of light to pass. When, on the contrary, they are tilted to their maximum in relation to a horizontal plane, they block out the light as much as possible. The drive device 5 comprises according to this example a drive shaft (not shown) oriented parallel to the pivot axis A of the slats. Cords 6, 6' in connection with this drive shaft are arranged in pairs on either side of the drive shaft of the drive device 5 so as to be reciprocally driven upwards or downwards. when rotating the drive shaft. In other words, a cord 6 of a pair of cords 6, 6' is lowered when the other cord 6' of this same pair is pulled upwards and vice versa. Each of the cords 6, 6' comprises at its end, or close to its end, a hooking device 61. The hooking device 61 is generally a ball but it can take the form of any element having a greater transverse dimension to the diameter of the corresponding cord. It can be for this purpose in the form of a transverse axis. Several pairs of cords 6, 6' are arranged along the drive axis. The number of cords 6, 6' corresponds to the number of cords 3, 3'.

Le dispositif d'entrainement 5 peut être mu manuellement, par exemple au moyen d'une manivelle. Le dispositif d'entrainement 5 peut alternativement être motorisé et activé sur demande au moyen d'un actionneur radio ou filaire..The drive device 5 can be moved manually, for example by means of a crank. The training device 5 can alternatively be motorized and activated on demand by means of a radio or wired actuator.

Chacune des cordelettes 6, 6' est connectée à un cordonnet 3, 3' au moyen d'un élément de connexion 1, 1' décrit ici. Les détails d'un élément de connexion 1, 1' selon la présente invention sont visibles à la figure 3. L'élément de connexion 1, 1' comporte une première face 10a opposée à une seconde face 10b ainsi qu'une première face latérale 10c opposée à une seconde face latérale 10d. Il est entendu que la première 10a et la seconde 10b faces ainsi que les première 10c et seconde 10d faces latérales désignent des surfaces externes de l'élément de connexion 1, 1'. L'une des première 10a et seconde 10b faces, ou les deux, peuvent être biseautées sur leur portion inférieure ou supérieure. De préférence, la première face 10a peut être biseautée sur sa portion inférieure. La seconde face 10b peut être quant à elle biseauté sur sa portion supérieure. La première face 10a comporte une tête de connexion 20 adaptée à maintenir une cordelette 6, 6' par son dispositif d'accroche 61. A cet effet, la tête de connexion 20 comporte une fente 21 ouverte sur l'une des faces de l'élément de connexion 1, 1' de sorte à pouvoir accueillir la cordelette 6, 6'. La largeur de la fente 21 est donc adaptée au diamètre de la cordelette 6, 6' c'est-à-dire que la largeur de la fente 21 est au moins égale au diamètre de la cordelette 6, 6'. Les cordelettes 6, 6' sont généralement de section circulaire, de sorte que leur orientation par rapport à la fente 21 reste sans importance. Les parties latérales de la tête de connexion 20, de part et d'autre de la fente 21, forment un moyen de rétention du dispositif d'accroche 61. Les deux parties latérales de la tête de connexion 20 peuvent par exemple former une cavité sphérique adaptée à l'accueil de la boule disposée à l'extrémité des cordelettes 6, 6' si tel est le dispositif d'accroche 61. Alternativement, les deux parties latérales de la tête de connexion 20 peuvent former un crochet propre à maintenir un axe transversal si tel est le dispositif d'accroche 61. Il est entendu que la tête de connexion 20 est complémentaire du dispositif d'accroche 61 et permet un accouplement aisé et réversible des éléments de connexion 1, 1' avec les cordelettes 6, 6' correspondantes. La première face 10a peut être biseautée dans sa partie inférieure de sorte à limiter l'encombrement et à faciliter l'insertion de la cordelette 6, 6' et de son dispositif d'accroche 61. La fente 21, disposée sur la partie supérieure de la tête de connexion 20 est de préférence ouverte du coté de la première face 10a et s'étend sur toute la hauteur de la première face 10a. La tête de connexion 20 est disposée de préférence sur la portion supérieure de la première face 10a. Each of the cords 6, 6' is connected to a cord 3, 3' by means of a connection element 1, 1' described here. The details of a connection element 1, 1' according to the present invention are visible in picture 3 . The connection element 1, 1' comprises a first face 10a opposite a second face 10b as well as a first side face 10c opposite a second side face 10d. It is understood that the first 10a and the second 10b faces as well as the first 10c and second 10d lateral faces denote external surfaces of the connection element 1, 1'. One of the first 10a and second 10b faces, or both, can be bevelled on their lower or upper portion. Preferably, the first face 10a can be bevelled on its lower portion. The second face 10b can be bevelled on its upper portion. The first face 10a comprises a connection head 20 adapted to hold a cord 6, 6' by its attachment device 61. For this purpose, the connection head 20 comprises a slot 21 open on one of the faces of the connection element 1, 1' so as to be able to accommodate the cord 6, 6'. The width of the slot 21 is therefore adapted to the diameter of the cord 6, 6', that is to say that the width of the slot 21 is at least equal to the diameter of the cord 6, 6' . The cords 6, 6' are generally of circular section, so that their orientation with respect to the slot 21 remains unimportant. The side parts of the connection head 20, on either side of the slot 21, form a retention means for the attachment device 61. The two side parts of the connection head 20 can for example form a spherical cavity adapted to receive the ball arranged at the end of the cords 6, 6' if such is the attachment device 61. Alternatively, the two lateral parts of the connection head 20 can form a hook capable of holding an axis transverse if such is the attachment device 61. It is understood that the connection head 20 is complementary to the attachment device 61 and allows easy and reversible coupling of the connection elements 1, 1 ' with the cords 6, 6' corresponding. The first face 10a can be bevelled in its lower part so as to limit the size and to facilitate the insertion of the cord 6, 6' and its attachment device 61. The slot 21, disposed on the upper part of the connection head 20 is preferably open on the side of the first face 10a and extends over the entire height of the first face 10a. The connection head 20 is preferably arranged on the upper portion of the first face 10a.

Dans toute la présente description, les termes «supérieur» et « inférieur » ont le sens communément admis et s'appliquent aux éléments de la présente invention, en particulier à l'élément de connexion 1, 1' lorsqu'il est en position de fonctionnement, monté sur une store vénitien.Throughout the present description, the terms “upper” and “lower” have the commonly accepted meaning and apply to the elements of the present invention, in particular to the connection element 1, 1′ when it is in the position of operation, mounted on a Venetian blind.

Les termes « vertical » et « horizontal » ont le sens communément admis et s'appliquent aux éléments de la présente invention dans leur position de fonctionnement.The terms "vertical" and "horizontal" have the commonly accepted meaning and apply to the elements of the present invention in their operating position.

L'élément de connexion 1, 1' comporte en outre, dans sa partie centrale, une fente de connexion 30 adaptée à recevoir un cordonnet 3, 3' du store vénitien S. La partie centrale de l'élément de connexion 1, 1' désigne son volume intérieur, ou la portion la plus centrale de son volume intérieur. La fente de connexion 30 comporte une première surface 30a, et une seconde surface 30b parallèles l'une à l'autre et en vis-à-vis l'une de l'autre. Les première 30a et seconde 30b surfaces de la fente de connexion 30 s'étendent sur toute la longueur de l'élément de connexion 1, 1' de sorte à ménager une ouverture à la fois dans la partie supérieure et dans la partie inférieure de l'élément de connexion 1, 1'. L'espacement entre les première 30a et seconde 30b surfaces de la fente de connexion 30 correspond au minimum à l'épaisseur d'un cordonnet 3, 3' du store vénitien S de sorte qu'il puisse y être inséré par son chant. La largeur des première 30a et seconde 30b surfaces peut correspondre à la largeur d'un cordonnet 3, 3' ou être supérieure à la largeur d'un cordonnet, de sorte qu'une fois inséré entre les première 30a et seconde 30b surfaces, il s'y inscrit totalement. Il n'est cependant pas exclut que la largeur des première 30a et seconde 30b surfaces de la fente de connexion 30 reste inférieure à celle d'un cordonnet 3, 3' sans préjudice sur l'opérabilité de la présente invention.The connection element 1, 1' further comprises, in its central part, a connection slot 30 adapted to receive a cord 3, 3' of the Venetian blind S. The central part of the connection element 1, 1' designates its interior volume, or the most central portion of its interior volume. The connection slot 30 comprises a first surface 30a, and a second surface 30b parallel to each other and facing each other. The first 30a and second 30b surfaces of the connection slot 30 extend over the entire length of the connection element 1, 1' so as to provide an opening both in the upper part and in the lower part of the 'connection element 1, 1'. The spacing between the first 30a and second 30b surfaces of the connection slot 30 corresponds at least to the thickness of a cord 3, 3' of the Venetian blind S so that it can be inserted therein by its edge. The width of the first 30a and second 30b surfaces can correspond to the width of a cord 3, 3' or be greater than the width of a cord, so that once inserted between the first 30a and second 30b surfaces, it fits in completely. However, it is not excluded that the width of the first 30a and second 30b surfaces of the connection slot 30 remains less than that of a cord 3, 3' without prejudice to the operability of the present invention.

La fente de connexion 30 est à cet effet ouverte sur l'une des faces latérales 10d de l'élément de connexion 1, 1'. Elle est ouverte sur toute sa longueur de sorte que l'ouverture latérale rejoigne les ouvertures de sa partie supérieure et de sa partie inférieure. De la sorte, les première 10a et seconde 10b faces de l'élément de connexion 1, 1' ne sont solidaires entre elles que par l'une des faces latérale 10c et totalement dissociées l'une d'elle sur l'autre face latérale 10d. Le cordonnet 3, 3' peut alors être inséré dans la fente de connexion 30 par sa tranche. Lorsque la largeur du cordonnet 3, 3' correspond à la largeur des premières 30a et seconde 30b surfaces de la fente de connexion, le cordonnet 3, 3' affleure sur la face latérale 10d. La largeur du cordonnet 3, 3' peut être cependant inférieure à la largeur des premières 30a et seconde 30b surfaces de la fente de connexion 30, pour autant que le cordonnet puisse y être fixé grâce au moyen de fixation 40 décrit plus bas. Rien n'empêche en outre de fixer un cordonnet 3, 3' plus large. Dans ce cas, il pourra dépasser de la surface latérale 10d mais pourra être maintenu à l'élément de connexion 1, 1' de manière tout aussi efficace. Cela représente un avantage notable en ce que l'élément de connexion 1, 1' peut être combiné à des cordonnets 3, 3' de toutes largeurs y compris à des cordonnets plus larges que la largeur de la fente de connexion 30. Cela représente l'avantage supplémentaire de ne pas être entravé par les boucles disposées sur la tranche du cordonnet 3, 3'. En particulier, l'élément de connexion 1, 1' peut être combiné au cordonnet 3, 3' à n'importe quelle position, y compris à une position sur le cordonnet 3, 3' comprenant une boucle. Dans ce cas, la boucle restera libre et dépassera de la face latérale 10c de l'élément de connexion 1, 1'. De préférence, l'élément de connexion 1, 1' est associé au cordonnet 3, 3' correspondant de sorte que le bord du cordonnet comportant les boucles soit disposé du côté de la face latérale ouverte 10d. La face latérale ouverte 10d de l'élément de connexion 1, 1' est ainsi disposée en vis-à-vis des lamelles Sn. The connection slot 30 is for this purpose open on one of the side faces 10d of the connection element 1, 1'. It is open along its entire length so that the side opening joins the openings of its upper part and its lower part. In this way, the first 10a and second 10b faces of the connection element 1, 1' are joined to each other only by one of the side faces 10c and completely separated from one of them on the other side face. 10d. The cord 3, 3' can then be inserted into the connection slot 30 by its edge. When the width of the cord 3, 3' corresponds to the width of the first 30a and second 30b surfaces of the connection slot, the cord 3, 3' is flush with the side face 10d. The width of the cord 3, 3' can however be less than the width of the first 30a and second 30b surfaces of the connection slot 30, provided that the cord can be fixed there using the fixing means 40 described below. There is also nothing to prevent a wider cord 3, 3' from being fixed. In this case, it may protrude from the side surface 10d but may be held to the connection element 1, 1' just as effectively. This represents a notable advantage in that the connection element 1, 1' can be combined with cords 3, 3' of any width including cords wider than the width of the connection slot 30. This represents the additional advantage of not being hindered by the loops arranged on the edge of the cord 3, 3' . In particular, the connection element 1, 1' can be combined with the cord 3, 3' at any position, including a position on the cord 3, 3' comprising a loop. In this case, the loop will remain free and will protrude from the side face 10c of the connection element 1, 1'. Preferably, the connection element 1, 1' is associated with the corresponding cord 3, 3' so that the edge of the cord comprising the loops is placed on the side of the open side face 10d. The open side face 10d of the connection element 1, 1' is thus arranged opposite the lamellae Sn.

L'une des faces latérale 10d de l'élément de connexion 1, 1' étant fendue sur toute sa longueur, un des deux bords du cordonnet 3, 3' reste totalement libre, même une fois que le cordonnet 3, 3' est associé à l'élément de connexion 1, 1'. Il est entendu que la fente de connexion 30 a une orientation verticale et correspond à l'orientation verticale des cordonnets 3, 3' une fois le store monté.One of the side faces 10d of the connection element 1, 1' being split along its entire length, one of the two edges of the cord 3, 3' remains completely free, even once the cord 3, 3' is associated to the connection element 1, 1'. It is understood that the connection slot 30 has a vertical orientation and corresponds to the vertical orientation of the cords 3, 3' once the blind is mounted.

Sur un même store vénitien S, tous les éléments de connexion 1, 1' peuvent être identiques, c'est-à-dire que la face latérale fendue 10d est la même pour tous les éléments de connexion. Alternativement, la face latérale fendue peut varier d'un élément de connexion à l'autre. Il peut être envisagé que le cordonnet 3 équipant le bord frontal BFn des lamelles Sn s'insère sur une face latérale de l'élément de connexion 1, et que le cordonnet 3' équipant le bord postérieur BPn des lamelles Sn s'insère sur la face latérale opposée de l'élément de connexion 1'. Dans ce cas, les éléments de connexion 1 et 1' sont images l'un de l'autre dans un miroir. Les éléments de connexion 1, 1' peuvent ainsi être orientés de manière symétrique par rapport au lamelles. Les éléments de connexion 1, 1' peuvent ainsi être tous disposés de sorte que leur face latérale ouverte soit en vis-à-vis des lamelles Sn. On the same Venetian blind S, all the connection elements 1, 1' can be identical, that is to say that the split side face 10d is the same for all the connection elements. Alternatively, the split side face may vary from one connection element to another. It can be envisaged that the cord 3 equipping the front edge BFn of the slats Sn is inserted on a side face of the connection element 1, and that the cord 3 ' fitting the posterior edge BPn of the slats Sn is inserted on the opposite side face of the connection element 1'. In this case, the connection elements 1 and 1' are images of each other in a mirror. The connection elements 1, 1' can thus be oriented symmetrically relative to the slats. The connection elements 1, 1' can thus all be arranged so that their open lateral face faces the lamellae Sn.

Les première 30a et seconde 30b surfaces de la fente de connexion 30 sont ainsi parallèles, ou substantiellement parallèles à la première 10a et à la seconde 10b faces de l'élément de connexion 1, 1', hors éventuels biseau. En outre, la fente de connexion 30 est décalée par rapport à la tête de connexion 20. La fente de connexion 30 est en effet en position centrale alors que la tête de connexion 20 est disposée sur la première face 10a de l'élément de connexion 1, 1'. Les cordonnets 3, 3' et les cordelettes 6, 6' correspondants se trouvent donc décalés l'un par rapport à l'autre, une fois qu'ils sont joints au moyen de l'élément de connexion 1, 1'. Leurs extrémités peuvent librement dépasser de l'élément de connexion 1, 1', ce qui est impossible ou malaisé lorsqu'elles sont en vis-à-vis l'une de l'autre. Cela permet de connecter le cordonnet 3, 3' à l'élément de connexion 1, 1' à n'importe quelle position, et de laisser libre son extrémité.The first 30a and second 30b surfaces of the connection slot 30 are thus parallel, or substantially parallel to the first 10a and to the second 10b faces of the connection element 1, 1', excluding any bevels. In addition, the connection slot 30 is offset with respect to the connection head 20. The connection slot 30 is in fact in a central position while the connection head 20 is arranged on the first face 10a of the connection element 1, 1'. The cords 3, 3' and the corresponding cords 6, 6' are therefore offset relative to each other, once they are joined by means of the connection element 1, 1'. Their ends can freely protrude from the connection element 1, 1', which is impossible or difficult when they are facing each other. This makes it possible to connect the cord 3, 3' to the connection element 1, 1' at any position, and to leave its end free.

Les première 30a et seconde 30b surfaces de la fente de connexion 30 peuvent être lisses. Alternativement, l'une ou les deux de ces surfaces peuvent être texturées de sorte à mieux maintenir le cordonnet 3, 3' et éviter tout glissement. Par exemple, l'une ou les deux de ces surfaces 30a, 30b peuvent être rainurées transversalement, c'est-à-dire selon une direction horizontale lorsque l'élément de connexion 1, 1' est monté sur un store vénitien. D'autres reliefs peuvent être envisagés, tels que des vaguelettes, des pointes, ou tout autre texture propre à limiter ou éviter le glissement du cordonnet 3, 3' le long des première 30a et seconde 30b surfaces de la fente de connexion 30. Alternativement, l'une ou les deux des première 30a et seconde 30b surfaces peuvent être revêtues d'un matériau antidérapant, tel qu'un caoutchouc ou un matériau polymère.The first 30a and second 30b surfaces of the connection slot 30 can be smooth. Alternatively, one or both of these surfaces can be textured so as to better hold the cord 3, 3' and avoid any slippage. For example, one or both of these surfaces 30a, 30b can be grooved transversely, that is to say in a horizontal direction when the connection element 1, 1' is mounted on a Venetian blind. Other reliefs can be envisaged, such as ripples, spikes, or any other texture capable of limiting or preventing the cord 3, 3' from slipping along the first 30a and second 30b surfaces of the connection slot 30. Alternatively , one or both of the first 30a and second 30b surfaces may be coated with a non-slip material, such as a rubber or polymeric material.

Les bords de la fente de connexion 30, sur la face latérale fendue 10d peuvent être droits. L'un ou les deux de ces bords peuvent cependant être chanfreinés pour faciliter l'engagement du cordonnet 3, 3' dans la fente de connexion 30. The edges of the connection slot 30, on the slotted side face 10d can be straight. One or both of these edges can however be chamfered to facilitate the engagement of the cord 3, 3' in the connection slot 30.

L'élément de connexion 1, 1' comporte en outre au moins un moyen de fixation 40 permettant de bloquer le cordonnet 3, 3' dans la fente de connexion 30 une fois qu'il y est inséré. Le moyen de fixation 40 est de préférence disposé sur la seconde face 10b de l'élément de connexion 1, 1'. Il est de préférence intégré à l'élément de connexion 1, 1'. De cette manière, il n'est pas utile de prévoir de pièces annexes à l'élément de connexion 1, 1'. En outre, le ou les moyens de fixation 40 sont de préférence non déformables de sorte à pouvoir être sollicité de multiples fois sans perte d'efficacité. Cela exclut par exemple la fixation des cordonnets 3, 3' par des languettes rabattables, dont la pression exercée sur les cordonnets s'amenuise au fur et à mesure de rabattements et déploiements successifs. De surcroît les languette rabattables peuvent être sujettes à des ruptures du fait des repliements répétés. Il est important que le moyen de fixation 40 permette des opérations répétées de fixation du cordonnet 3, 3' sans perte d'efficacité. Cela facilite notamment les différents réglages, ou remplacement de cordonnets usagés, qui peuvent survenir lors de l'entretien des stores vénitiens. Le ou les moyens de fixation 40 sont choisis de sorte à permettre une automatisation aisée de la fixation du cordonnet 3, 3' sur l'élément de connexion 1, 1'. The connection element 1, 1' further comprises at least one fastening means 40 making it possible to block the cord 3, 3' in the connection slot 30 once it is inserted therein. The fixing means 40 is preferably arranged on the second face 10b of the connection element 1, 1'. It is preferably integrated into the connection element 1, 1'. In this way, it is not necessary to provide additional parts to the connection element 1, 1'. In addition, the fixing means 40 are preferably non-deformable so that they can be stressed multiple times without loss of effectiveness. This excludes, for example, the fixing of the cords 3, 3' by folding tongues, the pressure exerted on the cords of which decreases as successive foldings and deployments take place. In addition, the folding tabs can be subject to breakage due to repeated folding. It is important that the fastening means 40 allow repeated fastening operations of the cord 3, 3' without loss of effectiveness. This facilitates in particular the various adjustments, or replacement of worn cords, which may occur during the maintenance of Venetian blinds. The fixing means 40 are chosen so as to allow easy automation of the fixing of the cord 3, 3' on the connection element 1, 1'.

La figure 3 montre un exemple de moyen de fixation 40 adapté aux exigences de la présente invention mentionnées ci-dessus. Le moyen de fixation 40 représenté ici comporte une vis insérée dans un filetage aménagé dans la seconde face 10b de l'élément de connexion 1, 1' perpendiculairement aux première 30a et seconde 30b surfaces de la fente de connexion 30. L'extrémité de la vis débouche dans la fente de connexion 30 de sorte à appuyer le cordonnet 3, 3' le long de la première surface 30a et ainsi le maintenir en place. Le moyen de fixation 40 peut bien entendu comprendre plus d'une vis, par exemple deux vis traversant la seconde face 10b pour mieux maintenir le cordonnet 3, 3' dans la fente de connexion 30. Dans ce cas, les vis peuvent être identiques ou bien différentes. L'extrémité de la, ou des vis peut être conique et faire office de pointeau sur le cordonnet 3, 3'. Alternativement, l'extrémité de la, ou des vis peut être aplanie pour une plus large surface de contact avec le cordonnet 3, 3'. Alternativement, l'extrémité de la, ou des vis peut être solidaire d'une pièce intermédiaire plate faisant office d'étau pour le cordonnet 3, 3'. Le moyen de fixation 40 peut alors être serré et desserré à volonté sans altération de la force de serrage. Le serrage peut en outre être facilement automatisé. Le moyen de fixation fait ainsi partie intégrante de l'élément de connexion 1, 1', ce qui limite à la fois le nombre de pièces et le nombre d'étapes dans le procédé de couplage.There picture 3 shows an example of fastening means 40 adapted to the requirements of the present invention mentioned above. The fixing means 40 represented here comprises a screw inserted in a thread arranged in the second face 10b of the connection element 1, 1' perpendicular to the first 30a and second 30b surfaces of the connection slot 30. The end of the screw opens into the connection slot 30 so as to press the cord 3, 3' along the first surface 30a and thus hold it in place. The fixing means 40 can of course comprise more than one screw, for example two screws passing through the second face 10b to better hold the cord 3, 3' in the connection slot 30. In this case, the screws can be identical or quite different. The end of the screw or screws can be conical and act as a needle on the cord 3, 3'. Alternatively, the end of the screw or screws can be flattened for a larger contact surface with the cord 3, 3'. Alternatively, the end of the screw(s) can be secured to a flat intermediate piece acting as a vice for the cord 3, 3'. The fastening means 40 can then be tightened and loosened at will without altering the clamping force. Clamping can also be easily automated. The fixing means thus forms an integral part of the connection element 1, 1', which limits both the number of parts and the number of steps in the coupling process.

L'élément de connexion 1, 1' est donc monopièce. Il peut être ainsi moulé d'un bloc, ou usiné ou être produit par impression 3D. Cela limite la variété des éléments à produire. L'élément de connexion 1, 1' peut être fait en métal ou en alliage métallique tel que de l'acier, de l'inox ou tout autre métal usuel. Il peut alternativement être fait de matériau polymère tel qu'un plastique dur, pour autant que sa tenue mécanique suffise à la fixation des cordonnets 3, 3'. The connection element 1, 1' is therefore one-piece. It can thus be molded from a block, or machined or produced by 3D printing. This limits the variety of items to produce. The connection element 1, 1' can be made of metal or of a metal alloy such as steel, stainless steel or any other usual metal. It can alternatively be made of polymeric material such as a hard plastic, provided that its mechanical strength is sufficient for fixing the cords 3, 3'.

Il est entendu que l'élément de connexion 1, 1', comprenant la tête de connexion 20, la fente de connexion 30 et le moyen de fixation 40, forme une pièce unique. Alternativement, dans le cas où l'élément de connexion 1, 1' comporte plusieurs pièces mobiles entre elles, elles forment un ensemble de pièces totalement intégrées, c'est-à-dire non dissociées les unes des autres. Dans le cas où le moyen de fixation 40 comporte une ou plusieurs vis, elles sont combinées au corps de l'élément de fixation lui-même et non à un sous-ensemble.It is understood that the connection element 1, 1', comprising the connection head 20, the connection slot 30 and the fixing means 40, forms a single piece. Alternatively, in the case where the connection element 1, 1' comprises several moving parts between them, they form a set of fully integrated parts, that is to say not separated from each other. others. In the case where the fastening means 40 comprises one or more screws, they are combined with the body of the fastening element itself and not with a sub-assembly.

L'élément de connexion 1, 1' de la présente description facilite l'accouplement des cordelettes 6, 6' du dispositif d'entrainement 5 avec les cordonnets 3, 3' correspondants. L'opération nécessite de combiner le cordonnet 3, 3' à l'élément de connexion 1, 1' et de le maintenir grâce au moyen de fixation 40. Cette opération est jusqu'à présent effectuée manuellement. En l'occurrence, les éléments de connexion actuels ne possèdent pas de fente latérale et impliquent d'insérer les cordonnets par leur extrémité, ce qui n'est pas automatisable. D'autres systèmes existent, mais ils comportent plusieurs pièces à assembler, ce qui complique le procédé. En particulier, lorsque le cordonnet est associé à l'élément de connexion par l'une de ses faces plates, le moyen de fixation ne peut être totalement intégré.The connection element 1, 1' of the present description facilitates the coupling of the cords 6, 6' of the drive device 5 with the corresponding cords 3, 3' . The operation requires the cord 3, 3' to be combined with the connection element 1, 1' and to be held in place by means of the fixing means 40. This operation has hitherto been carried out manually. In this case, the current connection elements do not have a side slot and involve inserting the cords by their end, which cannot be automated. Other systems exist, but they include several parts to be assembled, which complicates the process. In particular, when the cord is associated with the connection element by one of its flat faces, the fixing means cannot be completely integrated.

La présente description couvre un procédé d'assemblage d'un élément de connexion 1, 1' tel que décrit ici, avec un cordonnet 3, 3' d'un store vénitien S. Si l'assemblage peut encore être fait manuellement, il représente l'avantage de pouvoir être facilement automatisé. Le procédé comprend notamment une étape d'insertion E1, lors de laquelle un cordonnet 3, 3' est inséré par son chant dans la fente de connexion 30. L'insertion peut être effectuée à n'importe quelle position du cordonnet 3, 3'. Le cordonnet 3, 3' est inséré de sorte que la surface de sa largeur soit insérée totalement ou au moins partiellement entre les première 30a et secondes 30b surfaces de la fente de connexion 30. L'insertion du cordonnet s'effectue par une face latérale 10d de l'élément de connexion 1, 1'. Le cordonnet 3, 3' est ainsi directement positionné dans l'élément de connexion 1, 1'. Le procédé comporte une seconde étape E2 de fixation du cordonnet 3, 3' dans la fente de connexion 30. La fixation s'effectue grâce au moyen de fixation 40 intégré à l'élément de connexion 1, 1'. Dans le cas où le moyen de fixation 40 est une vis, ou plusieurs vis, elles peuvent être vissées automatiquement. Le procédé d'assemblage est de préférence limité au deux étapes d'insertion E1 et de fixation E2. Le procédé peut être appliqué de manière automatique en première monte, lors de la fabrication des stores vénitiens.This description covers a method of assembling a connection element 1, 1' as described here, with a cord 3, 3' of a Venetian blind S. If the assembly can still be done manually, it represents the advantage of being easily automated. The method comprises in particular an insertion step E1, during which a cord 3, 3' is inserted by its edge into the connection slot 30. The insertion can be carried out at any position of the cord 3, 3' . The cord 3, 3' is inserted so that the surface of its width is totally or at least partially inserted between the first 30a and second 30b surfaces of the connection slot 30. The cord is inserted via a side face 10d of the connection element 1, 1'. The cord 3, 3' is thus directly positioned in the connection element 1, 1'. The method comprises a second step E2 of fixing the cord 3, 3' in the connection slot 30. The fixing takes place using the fixing means 40 integrated into the connection element 1, 1'. In the case where the fixing means 40 is a screw, or several screws, they can be screwed in automatically. The assembly process is preferably limited to the two steps of insertion E1 and fixing E2. The process can be applied automatically as original equipment, during the manufacture of Venetian blinds.

Outre le procédé d'assemblage, l'élément de connexion 1, 1' facilite d'éventuelles opérations de réglage, lors du montage des stores vénitiens ou après leur montage. Le précédé de réglage peut aisément être fait manuellement en un nombre d'étapes limités. Il suffit par exemple de desserrer le ou les moyens de fixation 40 de sorte à permettre le glissement du cordonnet dans la fente de connexion 30, de glisser l'élément de connexion 1, 1' le long du cordonnet 3, 3' jusqu'à la position requise, puis de resserrer le moyen de fixation 40. Le procédé de réglage s'applique également lors du remplacement d'un cordonnet 3, 3'. In addition to the assembly process, the connection element 1, 1' facilitates any adjustment operations, during the assembly of the Venetian blinds or after their assembly. The adjustment procedure can easily be done manually in a limited number of steps. It suffices, for example, to loosen the fixing means 40 so as to allow the cord to slide in the connection slot 30, to slide the connection element 1, 1' along the cord 3, 3' until the required position, then to tighten the fastening means 40. The adjustment method also applies when replacing a cord 3, 3'.

La présente description couvre l'élément de connexion 1, 1' décrit ci-dessus, le procédé d'assemblage de cet élément de connexion avec un cordonnet 3, 3', le procédé de réglage de la position de cet élément de connexion sur le cordonnet, ainsi qu'un store vénitien S comprenant au moins un de ces éléments de connexion 1, 1'. En particulier, le store vénitien S selon la présente invention comporte au moins un cordonnet 3, 3' dont un chant est pourvu de plusieurs boucles chacune liée au bord d'une lamelle Sn, et au moins une cordelette d'entrainement 6, 6' liée au cordonnet au moyen d'un élément de connexion ici décrit, de sorte que l'un des chants du cordonnet 3, 3' reste libre.This description covers the connection element 1, 1' described above, the method of assembling this connection element with a cord 3, 3', the method of adjusting the position of this connection element on the cord, as well as a Venetian blind S comprising at least one of these connection elements 1, 1'. In particular, the Venetian blind S according to the present invention comprises at least one drawstring 3, 3' , one edge of which is provided with several loops each linked to the edge of a slat Sn, and at least one drive cord 6, 6' linked to the cord by means of a connection element described here, so that one of the edges of the cord 3, 3' remains free.
