Abstract

The roller has a tube (1) with two ends each equipped with a bearing (3,4). A reeling spring (10) is mounted inside the tube and has an end fixed for rotation with one of the bearings and an opposed end fixed for rotation with the tube. The bearing with which the end of the spring is connected has a breakable indexing lug (12) cooperating with a seating (13) in the tube to oppose rotation of the tube with respect to the bearing.

Description

La présente invention concerne un rouleau enrouleur de store prébandé. The present invention relates to a pre-banded roller blind roller.

Un store, par exemple de véhicule automobile, comporte principalement une toile d'occultation attelée par l'un de ses bords à un rouleau enrouleur et équipée à son bord opposé d'une barre de tirage. Le rouleau à enrouleur est monté, le plus souvent à l'intérieur d'un boîtier, pour tourner autour de son axe et est sollicité par un couple de rappel permanent tendant à enrouler la toile sur le rouleau. A blind, for example of a motor vehicle, mainly comprises a blackout fabric coupled by one of its edges to a winding roller and equipped at its opposite edge with a draw bar. The winding roller is mounted, most often inside a housing, to rotate around its axis and is stressed by a permanent return torque tending to wind the fabric on the roller.

Le rouleau est principalement constitué d'un tube équipé à ses deux extrémités de paliers solidaires du boîtier et présentant une portion cylindrique pénétrant partiellement à l'intérieur du tube pour permettre une rotation libre de celui-ci. Le couple de rappel permanent du tube est exercé par un ressort qui s'étend à l'intérieur du tube et qui possède une extrémité solidaire de l'un des paliers et une autre extrémité solidaire d'un bloc d'ancrage fixé dans le tube. The roller mainly consists of a tube fitted at its two ends with bearings integral with the housing and having a cylindrical portion partially penetrating inside the tube to allow free rotation of the latter. The permanent return torque of the tube is exerted by a spring which extends inside the tube and which has one end secured to one of the bearings and another end secured to an anchoring block fixed in the tube. .

Selon l'invention, on propose un rouleau enrouleur de store prébandé, comportant un tube ayant deux extrémités équipées chacune d'un palier, un ressort d'enroulement disposé à l'intérieur du tube et possédant une extrémité solidaire en rotation de l'un des paliers et une extrémité opposée solidaire en rotation du tube, le palier dont l'extrémité du ressort est solidaire étant équipé d'un ergot d'indexation cassable coopérant avec une encoche du tube pour s'opposer à la rotation du tube par rapport au palier. Le ressort peut ainsi être prébandé et maintenu dans cet état grâce à l'ergot d'indexation du palier qui coopère avec l'encoche du tube pour s'opposer à la rotation du tube par rapport à ce palier. Lors de la première utilisation, un effort de traction est exercé sur la toile associée au rouleau. Le couple exercé par la toile sur le tube engendre la rupture de l'ergot d'indexation, de sorte que la liberté de rotation du tube par rapport au palier est rétablie. L'enroulement de la toile sur le tube peut alors s'opérer normalement, sans autre manipulation, grâce au prébandage initial du ressort. According to the invention, a pre-banded roller blind roller is proposed, comprising a tube having two ends each equipped with a bearing, a winding spring disposed inside the tube and having an end integral in rotation with one bearings and an opposite end integral in rotation with the tube, the bearing whose end of the spring is integral being equipped with a breakable indexing lug cooperating with a notch in the tube to oppose the rotation of the tube relative to the bearing. The spring can thus be pre-banded and maintained in this state thanks to the indexing lug of the bearing which cooperates with the notch of the tube to oppose the rotation of the tube relative to this bearing. During the first use, a tensile force is exerted on the fabric associated with the roller. The torque exerted by the fabric on the tube generates the rupture of the indexing lug, so that the freedom of rotation of the tube relative to the bearing is restored. The winding of the canvas on the tube can then operate normally, without further manipulation, thanks to the initial pre-banding of the spring.

D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description qui suit d'un de ses modes de réalisation donnés à titre d'exemple non limitatif. Other characteristics and advantages of the invention will appear on reading the following description of one of its embodiments given by way of nonlimiting example.

Il sera fait référence aux dessins en annexe, parmi lesquels
- la figure 1 est une vue en perspective d'un rouleau enrouleur de store conforme à l'invention
- la figure 2 est une vue en coupe selon un plan axial du rouleau de la figure 1.
Reference will be made to the accompanying drawings, among which
- Figure 1 is a perspective view of a roller blind roller according to the invention
- Figure 2 is a sectional view along an axial plane of the roller of Figure 1.

En référence aux figures 1 et 2, le rouleau enrouleur de store comporte un tube 1 d'axe 2 ayant deux extrémités ouvertes équipées chacune d'un palier 3, 4. With reference to FIGS. 1 and 2, the roller blind roller comprises a tube 1 of axis 2 having two open ends each equipped with a bearing 3, 4.

Chaque palier 3, 4, est en forme de bouchon et comporte une portion cylindrique 3.1, 4.1 qui pénètre partiellement à l'intérieur du tube 1 pour permettre une rotation libre de ce tube par rapport au palier 3, 4. Chaque palier 3, 4 présente en outre un logement 5 destiné à recevoir des doigts de fixation 6, 7 de deux éléments de support 8, 9 associés tels que des pattes solidaires d'un boîtier (non représenté) contenant le rouleau équipé de sa toile (non représentée).Each bearing 3, 4 is in the form of a plug and has a cylindrical portion 3.1, 4.1 which partially penetrates inside the tube 1 to allow free rotation of this tube relative to the bearing 3, 4. Each bearing 3, 4 further has a housing 5 intended to receive fixing fingers 6, 7 of two support elements 8, 9 associated such as lugs secured to a housing (not shown) containing the roller equipped with its fabric (not shown).

Les logements 5 des paliers 3, 4 sont ici à section polygonale et les doigts 6, 7 sont de section correspondante, de sorte que les paliers 3, 4 sont fixes en rotation. The housings 5 of the bearings 3, 4 are here of polygonal section and the fingers 6, 7 are of corresponding section, so that the bearings 3, 4 are fixed in rotation.

Un ressort hélicoïdal 10 est disposé à l'intérieur du tube 1 pour exercer sur celui-ci un couple de rappel élastique permanent tendant à enrouler la toile sur le tube 1. Le ressort 10 possède une extrémité solidaire en rotation du palier 4 (qui est lui-même solidaire en rotation des éléments supports 8, 9) et une extrémité opposée solidaire en rotation d'un bloc d'ancrage 11, luimême solidaire en rotation du tube 1 et disposé à l'intérieur de celui-ci. On comprend que lorsque le tube 1 pivote autour de son axe 2 pour le déploiement de la toile (non représentée) qui lui est associée, le bloc d'ancrage 11 pivote également et entraîne l'extrémité du ressort 10 dont il est solidaire. Le ressort 10, dont l'autre extrémité est fixe, se bande progressivement et exerce sur le bloc 11 un couple élastique de rappel. Lorsque la toile est relâchée, le ressort 10 entraîne en rotation le bloc d'ancrage 11 qui entraîne lui-même le tube 1 dans le sens de l'enroulement de la toile sur le tube. A helical spring 10 is disposed inside the tube 1 to exert on it a permanent elastic return torque tending to wind the fabric on the tube 1. The spring 10 has an end integral in rotation with the bearing 4 (which is itself integral in rotation with the support elements 8, 9) and an opposite end integral in rotation with an anchoring block 11, itself integral in rotation with the tube 1 and disposed inside of it. It is understood that when the tube 1 pivots about its axis 2 for the deployment of the fabric (not shown) which is associated with it, the anchoring block 11 also pivots and drives the end of the spring 10 of which it is integral. The spring 10, the other end of which is fixed, becomes progressively bandaged and exerts on the block 11 an elastic return torque. When the fabric is released, the spring 10 rotates the anchoring block 11 which itself drives the tube 1 in the direction of the winding of the fabric on the tube.

Le palier 4 est équipé d'un ergot radial d'indexation 12 qui coopère avec une encoche correspondante 13 ménagée dans le tube 1 et ouverte à l'extrémité de celuici. L'ergot 12 est réalisé en un matériau cassable tel qu'une matière plastique. Il présente éventuellement une restriction ou encoche d'amorce de rupture. The bearing 4 is equipped with a radial indexing lug 12 which cooperates with a corresponding notch 13 formed in the tube 1 and open at the end of it. The lug 12 is made of a breakable material such as a plastic. It may have a restriction or notch at the start of the rupture.

Lorsqu'il est engagé dans l'encoche 13, l'ergot 12 s'oppose à la rotation du tube 1 par rapport au palier 4. Ce dispositif d'anti-rotation permet, lors de la fabrication du rouleau, de prébander le ressort 10 et de maintenir le rouleau dans cette configuration prébandée prête à l'utilisation, sans qu'il 'soit nécessaire de recourir à un système d'indexation extérieur plus sophistiqué et donc plus coûteux. When it is engaged in the notch 13, the lug 12 opposes the rotation of the tube 1 relative to the bearing 4. This anti-rotation device makes it possible, during the manufacture of the roller, to prebend the spring 10 and to keep the roller in this pre-banded configuration ready for use, without the need to resort to a more sophisticated and therefore more expensive external indexing system.

Lors de la première utilisation du rouleau, le déploiement de la toile associée au tube 1 provoque la rupture de l'ergot 12, ce qui libère la rotation du tube 1 par rapport au palier 4. Le ressort 10, qui exerce sur le tube 1 un couple permanent d'enroulement de la toile, peut alors entraîné en rotation le tube 1 dans le sens de l'enroulement de la toile. When the roller is used for the first time, the deployment of the fabric associated with the tube 1 causes the lug 12 to rupture, which frees the rotation of the tube 1 relative to the bearing 4. The spring 10, which exerts on the tube 1 a permanent winding torque of the fabric, can then rotate the tube 1 in the direction of the winding of the fabric.

On notera que la résistance mécanique de l'ergot 12 doit être à la fois suffisamment élevée pour résister au couple de prébandage du ressort 10 avant la première utilisation du rouleau et suffisamment faible pour permettre une rupture aisée de cet ergot lors de la première utilisation, le déploiement du store étant manuel. It will be noted that the mechanical resistance of the lug 12 must be both sufficiently high to resist the pre-bandage torque of the spring 10 before the first use of the roller and sufficiently low to allow easy breakage of this lug during the first use, the deployment of the blind being manual.

L'invention n'est pas limitée au mode de réalisation qui vient d'être décrit, mais englobe au contraire toute variante reprenant, avec des moyens équivalents, les caractéristiques essentielles de l'invention. The invention is not limited to the embodiment which has just been described, but on the contrary encompasses any variant incorporating, with equivalent means, the essential characteristics of the invention.

Par exemple, bien qu'il ait été décrit un rouleau comportant un ergot d'indexation cassable, il est également possible d'utiliser un ergot d'indexation détachable, encliqueté ou emboîté dans un logement du palier auquel il est associé.  For example, although a roller has been described comprising a breakable indexing lug, it is also possible to use a detachable indexing lug, snapped or fitted into a housing of the bearing with which it is associated.
