Description

DISPOSITIF PERMETTANT L'ENROULEMENT
ET LE DEROULEMENT D'UNE TOILE
La présente invention concerne les dispositifs permettant d'enrouler et de dérouler, en totalité ou en partie selon les besoins, une toile. De tels dispositifs sont plus particulièrement employés pour manoeuvrer des stores ou tout autre moyen similaire de protection ou d'occultation présentant une certaine souplesse afin qu'ils puissent être enroulés sur eux-même.
DEVICE FOR WINDING
AND THE CONDUCT OF A CANVAS
The present invention relates to devices for winding and unwinding, in whole or in part as required, a canvas. Such devices are more particularly used for operating blinds or any other similar means of protection or concealment having a certain flexibility so that they can be rolled up on themselves.

Généralement, dans les dispositifs de ce genre, la toile est fixée à l'une de ses extrémités à un tambour horizontal et à son autre extrémité à un profilé mobile le long de deux rails verticaux bordant ladite toile. Generally, in devices of this kind, the fabric is fixed at one of its ends to a horizontal drum and at its other end to a movable profile along two vertical rails bordering said fabric.

Dans certains dispositifs, afin de faciliter les translations du profilé et d'obtenir une tension correcte de la toile, on met en oeuvre une paire de câbles qui circulent sur trois jeux de poulies : des premières poulies calées de part et d'autre du tambour, des secondes poulies fixées aux extrémités des rails opposées audit tambour et des troisièmes poulies calées de part et d'autre du profilé mobile, les axes de rotation de ces dernières poulies étant perpendiculaires aux axes de rotation des premières et secondes poulies. Les câbles sont ainsi fixés par une première de leurs extrémités aux premières poulies et sont réunis par leur seconde extrémité au niveau du profilé, après qu'ils aient été renvoyés par les secondes poulies et déviés vers le profilé par les troisièmes poulies.In certain devices, in order to facilitate the translations of the profile and to obtain a correct tension of the fabric, a pair of cables is used which circulate on three sets of pulleys: first pulleys wedged on either side of the drum , second pulleys fixed to the ends of the rails opposite said drum and third pulleys wedged on either side of the movable profile, the axes of rotation of the latter pulleys being perpendicular to the axes of rotation of the first and second pulleys. The cables are thus fixed by a first of their ends to the first pulleys and are joined by their second end at the level of the profile, after they have been returned by the second pulleys and deflected towards the profile by the third pulleys.

Dans quelques dispositifs connus, et notamment dans ceux décrits par le FR-A-2.546.869 ou par le EP-A-0.207.040, les secondes extrémités des câbles sont réunies par l'intérmédiaire d'un ressort logé dans le profilé et qui, par la traction exercée sur les câbles, permet d'assurer une certaine tension de la toile. In some known devices, and in particular in those described by FR-A-2,546,869 or by EP-A-0,207,040, the second ends of the cables are joined by means of a spring housed in the profile and which, by the traction exerted on the cables, makes it possible to ensure a certain tension of the fabric.

Les mécanismes de ce type ne sont pas toujours d'une grande fiabilité et d'une longévité à toute épreuve. En effet, les déplacements répétés du profilé en fonction des besoins de l'utilisateur et donc les multiples sollicitations transmises par les câbles, peuvent au bout d'un certain temps entraîner une distension du ressort et rendre inopérant le dispositif. Dans le cas par ailleurs du dispositif décrit par le EP-A-0.207.040, les câbles sont réunis par le ressort au moyen d'un quatrième jeu de poulies, lesdites poulies étant fixées aux extrémités du ressort de telle sorte qu'elles suivent étroitement les mouvements d'extension et de rétraction de ce ressort.Dépourvues ainsi de point d'appui, les poulies se trouvent en quelque sorte suspendues au ressort et peuvent venir heurter les bords intérieurs du profilé ou provoquer des torsions au niveau de la partie terminale des câbles. Mechanisms of this type are not always very reliable and longevity foolproof. Indeed, the repeated movements of the profile according to the needs of the user and therefore the multiple stresses transmitted by the cables, can after a certain time cause a distension of the spring and render the device inoperative. In the case, moreover, of the device described by EP-A-0.207.040, the cables are joined by the spring by means of a fourth set of pulleys, said pulleys being fixed to the ends of the spring so that they follow tightly extend and retract movements of this spring. Without a fulcrum, the pulleys are in a way suspended from the spring and can strike the inside edges of the profile or cause torsions at the end part Cables.

Le dispositif selon l'invention ne présente pas les inconvénients des dispositifs de l'art antérieur qui viennent d'être évoqués. The device according to the invention does not have the drawbacks of the devices of the prior art which have just been mentioned.

Plus précisément, l'invention a pour objet un dispositif permettant l'enroulement et le déroulement d'une toile fixée à l'une de ses extrémités à un tambour horizontal et à son autre extrémité à un profilé mobile le long de deux rails verticaux bordant ladite toile, ledit dispositif comprenant une paire de câbles tendus entre trois jeux de poulies, des premières poulies étant calées de part et d'autre dudit tambour, des secondes poulies étant fixées aux extrémités desdits rails opposées audit tambour et des troisièmes poulies étant calées de part et d'autre dudit profilé, lesdits câbles étant ainsi fixés par une première de leurs extrémités aux premières poulies et étant réunis par leur seconde extrémité au niveau dudit profilé par des moyens de tension élastiques, après que lesdits câbles aient été détournés sur les secondes et troisisèmes poulies, lesdits moyens de tension élastiques comprenant notamment un ressort. Ce dispositif est remarquable en ce que lesdits moyens de tension élastiques comprennent en outre un tendeur au moins coopérant avec ledit ressort. More specifically, the subject of the invention is a device allowing the winding and unwinding of a fabric fixed at one of its ends to a horizontal drum and at its other end to a movable profile along two vertical rails bordering said fabric, said device comprising a pair of cables stretched between three sets of pulleys, first pulleys being wedged on either side of said drum, second pulleys being fixed to the ends of said rails opposite to said drum and third pulleys being wedged on either side of said profile, said cables thus being fixed by a first of their ends to the first pulleys and being joined by their second end at said profile by elastic tensioning means, after said cables have been diverted over the seconds and third pulleys, said elastic tensioning means comprising in particular a spring. This device is remarkable in that said elastic tensioning means further comprise a tensioner at least cooperating with said spring.

La présence de ce tendeur est particulièrement intéressante. Il autorise en effet des réglages de la tension des câbles après la pose du dispositif, en permettant de compenser les éventuels relâchements du ressort. The presence of this tensioner is particularly interesting. It in fact authorizes adjustments to the cable tension after the device has been installed, making it possible to compensate for any loosening of the spring.

De la sorte, il constitue un élément déterminant de la durée de vie du produit.In this way, it constitutes a determining factor in the life of the product.

D'autres caractéristiques et avantages de la présente invention apparaîtront clairement à la lecture de la description qui suit d'un exemple de réalisation d'un dispositif conçu conformément aux enseignements de ladite invention, cet exemple étant donné à titre simplement d'illustration et sans aucun caractère limitatif. Other characteristics and advantages of the present invention will become apparent on reading the following description of an exemplary embodiment of a device designed in accordance with the teachings of said invention, this example being given by way of illustration only and without no limiting character.

Cette description est accompagnée d'un dessin dont la Figure unique représente, selon une vue en perspective éclatée, l'ensemble de ce dispositif. This description is accompanied by a drawing, the single Figure of which represents, in an exploded perspective view, the whole of this device.

De manière connue, le dispositif illustré est constitué d'un tambour horizontal 2 qui peut être motorisé et sur lequel est fixée une toile 1, l'autre extrémité de ladite toile étant retenue par un profilé 3 apte à coulisser le long de deux rails verticaux 4 et 5 espacés l'un de l'autre d'une distance sensiblement égale à la largeur de la toile. Comme on peut le voir, le tambour 2 et son mécanisme d'entraînement seront protégés par un carter 20 muni d'une fenêtre longitudinale afin de ménager un passage pour la toile. Un tel ensemble pourra ainsi être monté par exemple sur la toiture d'une véranda. In known manner, the illustrated device consists of a horizontal drum 2 which can be motorized and on which is fixed a fabric 1, the other end of said fabric being retained by a profile 3 capable of sliding along two vertical rails 4 and 5 spaced from each other by a distance substantially equal to the width of the fabric. As can be seen, the drum 2 and its drive mechanism will be protected by a casing 20 provided with a longitudinal window in order to provide a passage for the fabric. Such an assembly can thus be mounted for example on the roof of a veranda.

De manière connue également, ce dispositif comprend une paire de câbles 6a et 6b, montrés partiellement en traits mixtes, qui circulent sur trois jeux de poulies principaux successifs. On distingue ainsi
- un premier jeu de poulies 2a, 2b calées de part et d'autre du tambour 2,
- un deuxième jeu de poulies 4a, 5b fixées respectivement aux extrémités des rails 4 et 5 qui sont opposées au tambour 2, et
- un troisième jeu de poulies 3a, 3b calées de part et d'autre du profilé mobile 3.
Also in known manner, this device comprises a pair of cables 6a and 6b, shown partially in phantom, which run on three successive sets of main pulleys. We thus distinguish
a first set of pulleys 2a, 2b wedged on either side of the drum 2,
a second set of pulleys 4a, 5b fixed respectively to the ends of the rails 4 and 5 which are opposite to the drum 2, and
- a third set of pulleys 3a, 3b wedged on either side of the movable profile 3.

Ainsi qu'on peut l'observer, les extrémités 60a et 60b des câbles 6a et 6b sont fixées respectivement aux poulies 2a, 2b et leurs extrémités 61a et 61b sont réunies au niveau du profilé mobile 3, les poulies 3a, 3b ayant pour rôle de détourner les brins terminaux desdits câbles vers l'intérieur de ce profilé. As can be observed, the ends 60a and 60b of the cables 6a and 6b are fixed respectively to the pulleys 2a, 2b and their ends 61a and 61b are joined at the level of the movable profile 3, the pulleys 3a, 3b having the role divert the terminal strands of said cables towards the inside of this profile.

Comme précisé plus avant, les extrémités 61a et 61b sont réunies par des moyens de tension élastiques qui, dans l'exemple illustré et selon une caractéristique particulièrement avantageuse de l'invention, comprennent deux ressorts 7 et 8 qui sont fixés respectivement par leurs extrémités 7a et 8a aux bords latéraux du profilé 3 et sont reliés par leurs extrémités 7b et 8b à un tendeur 9 qui est constitué de deux tiges filetées 9a, 9b à pas de vis inversés, accouplées au moyen d'un manchon taraudé 10. De la sorte, en faisant tourner sur lui-même le manchon 10, il sera possible d'écarter ou de rapprocher l'une de l'autre les tiges filetées 9a, 9b et de modifier ainsi la longueur du tendeur 9 et donc de tendre plus ou moins les ressorts 7 et 8. As specified above, the ends 61a and 61b are joined by elastic tensioning means which, in the example illustrated and according to a particularly advantageous characteristic of the invention, comprise two springs 7 and 8 which are fixed respectively by their ends 7a and 8a to the lateral edges of the profile 3 and are connected by their ends 7b and 8b to a tensioner 9 which consists of two threaded rods 9a, 9b with inverted threads, coupled by means of a threaded sleeve 10. In this way , by rotating the sleeve 10 on itself, it will be possible to move apart or bring one towards the other the threaded rods 9a, 9b and thus to modify the length of the tensioner 9 and therefore to tension more or less springs 7 and 8.

A cet effet, et comme montré par les dessins, les extrémités 61a et 61b des câbles 6a et 6b sont fixées respectivement aux extrémités 7b et 8b des ressorts 7 et 8, ceci après que les brins terminaux desdits câbles aient été détournés à nouveau sur un quatrième jeu de poulies 90a et 90b solidaires du tendeur 9, lesdites quatrièmes poulies étant plus précisément fixées aux extrémités des tiges filetées 9a, 9b. To this end, and as shown in the drawings, the ends 61a and 61b of the cables 6a and 6b are fixed respectively to the ends 7b and 8b of the springs 7 and 8, this after the terminal strands of said cables have been diverted again on a fourth set of pulleys 90a and 90b integral with the tensioner 9, said fourth pulleys being more precisely fixed to the ends of the threaded rods 9a, 9b.

La liaison mécanique ainsi réalisée entre les ressorts 7 et 8 et le tendeur 9 au moyen des câbles 6a, 6b, qui peuvent se mouvoir sur les pou lies 90a et 90b, est particulièrement fiable et procure une répartition parfaite des efforts. Les ressorts peuvent sans dommage subir de nombreuses sollicitations dans la mesure notamment où ils disposent d'un point d'ancrage sur le profilé mobile 3, ceci aux niveaux de leurs extrémités 7a et 8a, ce qui n'existait pas jusqu'alors avec les dispositifs de l'art antérieur. The mechanical connection thus produced between the springs 7 and 8 and the tensioner 9 by means of the cables 6a, 6b, which can move on the lice 90a and 90b, is particularly reliable and provides a perfect distribution of the forces. The springs can, without damage, undergo numerous stresses, in particular insofar as they have an anchoring point on the movable profile 3, this at their ends 7a and 8a, which previously did not exist with the prior art devices.

On s'aperçoit ainsi de tous les avantages qui peuvent être tirés d'un tel dispositif. L'un des plus intéressants est procuré par le tendeur 9 qui, à tout moment en cours d'utilisation, permettra de rétablir la tension correcte des ressorts et de maintenir ainsi la traction exercée sur les câbles.  One thus realizes all the advantages which can be drawn from such a device. One of the most interesting is provided by the tensioner 9 which, at any time during use, will restore the correct tension of the springs and thus maintain the traction exerted on the cables.
