Ce dispositif peut ainsi être monté plus simplement qu'un dispositif tel que celui décrit dans la demande EP 1 087 095 .This device can thus be mounted more simply than a device such as that described in the application EP 1 087 095 .

Le but de l'invention est de réaliser un dispositif de manoeuvre palliant le problème précité et améliorant les dispositifs de l'art antérieur. En particulier, l'invention propose un dispositif simple, réalisé en un minimum de pièces, permettant de faciliter l'introduction des cordons dans le support du tambour d'enroulement et permettant l'automatisation de cette tâche.The object of the invention is to provide a maneuvering device that overcomes the aforementioned problem and improves the devices of the prior art.

Deux dispositifs de manoeuvre 20 tels que celui représenté aux figures 1 et 2 sont destinés au maintien d'un store vénitien. Chaque dispositif 20 comporte un cordon de suspension 2 dont une extrémité 3 est fixée à un tambour d'enroulement 4 et dont l'autre extrémité est fixée à l'extrémité libre du store. Il comporte en outre un cordon 5 d'orientation entraîné par une poulie à gorge 6 du tambour d'enroulement et lié à chacune des lames du store. Ainsi, le déplacement du cordon 5 permet l'orientation des lames autour de leurs axes longitudinaux.Two operating devices 20 such as the one shown in Figures 1 and 2 are intended for the maintenance of a venetian blind. Each device 20 comprises a suspension cord 2, one end 3 of which is fixed to a winding drum 4 and whose other end is fixed to the free end of the blind. It further comprises an orientation cord 5 driven by a grooved pulley 6 of the winding drum and connected to each blade of the blind. Thus, the displacement of the bead 5 allows the orientation of the blades around their longitudinal axes.

Ce dispositif de manoeuvre est installé dans un rail 7, présentant une lumière 10 de passage des cordons 2, 5, fixé à la structure du bâtiment qu'il équipe. On trouve dans ce rail outre le tambour d'enroulement 4, un support 9 le guidant en rotation et un arbre 8 de transmission du mouvement d'un motoréducteur ou d'un dispositif manuel tel qu'une manivelle vers le tambour d'enroulement. Les brins des cordons de suspension 2 et d'orientation 5 traversent le support 9 de tambour comme représenté à la figure 1.This operating device is installed in a rail 7, having a passage 10 of the cords 2, 5, fixed to the structure of the building it equips. In this rail is found in addition to the winding drum 4, a support 9 guiding it in rotation and a shaft 8 for transmitting the movement of a geared motor or a manual device such as a crank to the winding drum. The strands of the suspension and orientation cords 5 pass through the drum support 9 as shown in FIG. figure 1 .

Le support 9 comprend une embase munie de trous de passage 21a, 21b pour le cordon 5 et 22 pour le cordon 2. Aux deux extrémités de cette embase s'élèvent deux oreilles 23 et 24. La première 23 présente un alésage 25 et la seconde présente un alésage 26 intercepté par une rainure. Ces deux oreilles permettent de supporter le tambour 4. En effet, celui-ci présente à ses extrémités deux portions épaulées présentant des diamètres égaux, au jeu de fonctionnement près, aux alésages 25 et 26 réalisés dans les oreilles. Ainsi, on introduit une extrémité du tambour 4 dans l'alésage 25 de la première oreille puis on insère l'autre extrémité du tambour dans l'alésage 26 de la deuxième oreille par déformation élastique de celle-ci. Par ces moyens, le tambour est guidé en rotation sur le support qui est fixé au rail.The support 9 comprises a base provided with through-holes 21a, 21b for the cord 5 and 22 for the cord 2. At the two ends of this base there are two lugs 23 and 24. The first 23 has a bore 25 and the second has a bore 26 intercepted by a groove. These two ears can support the drum 4. In fact, it has at its ends two stepped portions having equal diameters, the operating clearance, the bores 25 and 26 made in the ears. Thus, one end of the drum 4 is introduced into the bore 25 of the first lug and then the other end of the drum is inserted into the bore 26 of the second lug by elastic deformation thereof. By these means, the drum is guided in rotation on the support which is fixed to the rail.

Le support 9 du tambour d'énroulement représenté aux figures 3 et 4 est réalisé en deux parties 9a et 9b qui sont assemblées après avoir positionné les brins des cordons 2 et 5 par rapport à l'une et l'autre d'entre elles. Ces deux parties 9a et 9b présentent des découpes telles qu'elles ne sont pas exactement complémentaires. Ainsi, lorsqu'on les assemble l'une à l'autre, des trous 21a, 21b et 22 d'axes verticaux sont préservés entre les deux parties 9a et 9b afin de permettre le passage des cordons 2 et 5. En particulier, les parties 9a et 9b présentent deux rainures 27, 28 d'axes verticaux permettant de réaliser le passage 22 et deux paires d'angles 29a, 30a et 29b, 30b permettant respectivement de réaliser les passages 21a et 21b. Les deux parties dont les formes sont représentées aux figures 5 et 6 peuvent en particulier être assemblées l'une à l'autre par emboîtement par déformation élastique. Elles peuvent encore être collées ou soudées. La partie 9a, respectivement la partie 9b comprend l'oreille 23, respectivement l'oreille 24. Ainsi, les parties 9a et 9b participent directement au support du tambour 4 par les actions de contact localisées au niveau des alésages 25 et 26. Elles reprennent l'ensemble des efforts exercés sur le tambour pour les transmettre au rail.The support 9 of the winding drum shown in FIGS. Figures 3 and 4 is made in two parts 9a and 9b which are assembled after positioning the strands of cords 2 and 5 relative to one and the other of them. These two parts 9a and 9b have cutouts such that they are not exactly complementary. Thus, when assembled to one another, holes 21a, 21b and 22 of vertical axes are preserved between the two parts 9a and 9b to allow the passage of the cords 2 and 5. In particular, the parts 9a and 9b have two grooves 27, 28 of vertical axes for making the passage 22 and two pairs of angles 29a, 30a and 29b, 30b respectively for making the passages 21a and 21b. Both parties whose forms are represented at Figures 5 and 6 can in particular be assembled to one another by interlocking by elastic deformation. They can still be glued or welded. Part 9a, respectively part 9b comprises ear 23, respectively ear 24. Thus, parts 9a and 9b participate directly in the support of drum 4 by contact actions located at bores 25 and 26. They resume all the forces exerted on the drum to transmit them to the rail.

Le procédé d'assemblage d'un tel support de tambour est ainsi simplifié. Ses étapes de réalisation se résument à :

  • introduction des brins de cordons à travers les trous pratiqués dans le rail,
  • positionnement des brins de cordons par rapport aux parties du support,
  • assemblage des parties du support,
  • mise en place du cordon d'orientation des lames dans la poulie à gorge,
  • fixation de l'extrémité du cordon de suspension au tambour d'enroulement,
  • mise en place du tambour d'enroulement dans le support,
  • installation de l'ensemble obtenu dans le rail.
The method of assembling such a drum support is thus simplified. Its stages of realization boil down to:
  • introduction of the strands of cords through the holes in the rail,
  • positioning the strands of cords with respect to the parts of the support,
  • assembly of the parts of the support,
  • setting up the orientation cord of the blades in the grooved pulley,
  • fixing the end of the suspension cord to the winding drum,
  • placing the winding drum in the support,
  • installation of the assembly obtained in the rail.

L'étape d'assemblage a pour conséquence d'emprisonner les brins de cordons dans des passages permettant le guidage de ceux-ci.The assembly step has the effect of enclosing the cords strands in passages for guiding them.

Il est à noter que les étapes de positionnement des brins des cordons par rapport aux parties du support et d'assemblage des parties du support peuvent se trouver juste avant l'étape de mise en place du tambour d'enroulement dans le support.It should be noted that the steps of positioning the strands of the cords with respect to the parts of the support and assembling the parts of the support can be just before the step of placing the winding drum in the support.
