Abstract
Description
La présente invention concerne un dispositif d'orientation des lamelles d'un store dit vénitien.The present invention relates to a device for orienting the slats of a so-called Venetian blind.
On connaît déjà de nombreuses réalisations de tels dispositifs d'orientation dénommés également variateurs, par exemple des brevets CH 400 817 et 454 417 ou du brevet EP 0 190 626, qui comportent une bobine d'enroulement montée dans un boîtier sur un axe de commande horizontal et soumise à l'action de moyens élastiques de freinage. Dans tous les dispositifs connus, les deux cordelettes auxquelles sont attachées les lamelles du store sont fixées par une de leurs extrémités à ladite bobine et sont par conséquent entraînées en rotation avec celle-ci. Cette particularité présente le désavantage que le poids des lamelles s'exerce sur les deux cordelettes et varie en fonction de la position du store, de telle sorte que la manipulation du variateur est plus ou moins difficile à effectuer selon cette position. De plus, les dispositifs connus nécessitent en principe la présence d'un système relativement complexe pour maintenir les lamelles dans leur position approximativement verticale donc fermée.Numerous embodiments of such orientation devices are also known, also known as variators, for example patents CH 400 817 and 454 417 or patent EP 0 190 626, which comprise a winding coil mounted in a housing on a control shaft. horizontal and subjected to the action of elastic braking means. In all known devices, the two cords to which the blind slats are attached are fixed by one of their ends to said coil and are therefore rotated therewith. This feature has the disadvantage that the weight of the slats is exerted on the two cords and varies according to the position of the blind, so that the handling of the dimmer is more or less difficult to perform depending on this position. In addition, the known devices in principle require the presence of a relatively complex system to maintain the slats in their approximately vertical position, therefore closed.
Le but de cette invention consiste donc à fournir un dispositif d'orientation des lamelles d'un store du type précité, mais qui ne présente pas les inconvénients précités des dispositifs connus.The object of this invention therefore consists in providing a device for orienting the slats of a blind of the aforementioned type, but which does not have the aforementioned drawbacks of the known devices.
Le dispositif d'orientation des lamelles d'un store, objet de la présente invention et visant à atteindre le but ci-dessus, se distingue par les caratéristiques définies dans la revendication 1.The device for orienting the slats of a blind, which is the subject of the present invention and which aims to achieve the above object, is distinguished by the characteristics defined. in claim 1.
Le dessin annexé illustre de manière schématique et à titre d'exemple une forme d'exécution du dispositif selon l'invention.The accompanying drawing illustrates schematically and by way of example an embodiment of the device according to the invention.
Les figures 1 et 2 en sont des vues latérales partiellement en coupe verticale et montrant le dispositif dans ses positions correspondant aux positions respectivement ouverte et fermée des lamelles.Figures 1 and 2 are side views partially in vertical section and showing the device in its positions corresponding to the respectively open and closed positions of the slats.
En référence aux figures 1 et 2, la forme d'exécution du dispositif selon l'invention comporte un boîtier 1 dans lequel est montée rotative une bobine d'enroulement 2 sur un axe transversal de commande 3. La rotation de cette bobine 2 est soumise de manière connue en elle-même à l'action d'un ressort de freinage 4 enroulé autour dudit axe de commande 3.Referring to Figures 1 and 2, the embodiment of the device according to the invention comprises a housing 1 in which a
Le dispositif illustré comporte encore une première cordelette 5 fixée par son extrémité supérieure au boîtier 1, et une seconde cordelette 6 solidaire par son extrémité supérieure de la bobine d'enroulement 2, les points d'ancrage respectifs étant désignés par les chiffres de référence 5' et 6'. Entre les deux cordelettes 5,6 sont montées les lamelles 7 du store, lesquelles sont plus particulièrement articulées sur des points de pivotement 8,9.The illustrated device also includes a
Bien entendu, le dispositif comporte également une bande de traction non illustrée ici et agissant de manière connue en elle-même pour commander la montée, respectivement la descente, des lamelles du store.Of course, the device also comprises a traction strip not illustrated here and acting in a manner known per se to control the raising, respectively the lowering, of the blind slats.
Dans la position "ouverte" illustrée sur la figure 1, les lamelles 7 sont donc pratiquement horizontales (angle d'environ 90° avec la verticale), alors que dans la position "fermée" illustrée sur la figure 2, elles sont pratiquement verticales (angle d'environ 0°).In the "open" position illustrated in FIG. 1, the
On constate ainsi que, grâce à la présente invention, dans la position verticale précitée (figure 2), le poids des lamelles 7 est supporté lors de la manoeuvre de descente du store par la seule cordelette fixe 5, lesdites lamelles 7 restant suspendues par leur point d'articulation 8 à celle-ci. Quelle que soit la position du store, la force exercée par le poids des lamelles 7 sur le ressort de freinage 4 reste donc nulle, et la manipulation du store, plus particulièrement pour sa descente, demande toujours le même effort. Le fait que tout le poids des lamelles 7 est supporté par la cordelette fixe 5 permet donc au dispositif de freinage ressort 4 enroulé autour de l'axe de la bobine 2 de travailler "librement", c'est-à-dire indépendamment de la manoeuvre de descente ou de montée des lamelles 7. Bien entendu, les lamelles 7 peuvent être orientées selon un angle quelconque entre environ 0° et 90°, le point d'articulation 8 des lamelles 7 sur la cordelette fixe 5 restant dans la même position, alors que l'autre point d'articulation 9 sur la cordelette 6 solidaire de la bobine d'enroulement décrit un arc de cercle entre les deux positions extrêmes décrites précédemment.It can thus be seen that, thanks to the present invention, in the above-mentioned vertical position (FIG. 2), the weight of the
Un autre avantage du dispositif selon l'invention consiste dans le fait que, lorsque la manoeuvre de descente du store est terminée, toutes les lamelles 7 restent automatiquement positionnées pratiquement verticalement, comme illustré sur la figure 2, c'est-à-dire en contact les unes avec les autres sous l'effet de leur propre poids, sans qu'il soit nécessaire de tendre ultérieurement la cordelette qui les soutient, contrairement aux dispositifs connus qui doivent être pourvus d'un système relativement sophistiqué et par là coûteux destiné à fournir aux lamelles la tension nécessaire pour rester dans ladite position.Another advantage of the device according to the invention consists in the fact that, when the maneuver for lowering the blind is completed, all the
Enfin, on peut encore relever que la conception du dispositif d'orientation des lamelles d'un store selon l'invention offre la possibilité de prévoir deux entre-axes différents entre la bande de traction (non illustrée) et les cordelettes, l'une des deux étant fixée au boîtier, ce qui permet aux constructeurs d'utiliser le même variateur, indépendamment du fait qu'ils aient leur machine réglée pour un entre-axe de 11 mm ou de 24 mm, par exemple. De plus, selon une variante non illustrée, le dispositif selon l'invention peut être combiné avec un système conventionnel dans lequel les deux cordelettes sont solidaires de la bobine de commande.Finally, it can also be noted that the design of the device for orienting the slats of a blind according to the invention offers the possibility of providing two different centers between the traction strip (not shown) and the cords, one of the two being fixed to the housing, which allows manufacturers to use the same variator, regardless of whether they have their machine adjusted for a center distance of 11 mm or 24 mm, for example. In addition, according to a variant not illustrated, the device according to the invention can be combined with a conventional system in which the two cords are integral with the control coil.
