Abstract

The webbing guide comprises a base (1) with several legs (2), providing an opening (4) for the passage of a rotating bearing (5). The bearing has an opening (9) for mounting of a roller bearing (10) giving automatic positioning of the roller bearing relative to the webbing track. The orientation of the lateral faces of the legs is not parallel, extending in an L, T or H shape. The bearings are located on each face along the secant rotational axes. Radial stops are included in the bearings which limit the rotational amplitude between two angular positions. A roller bearing cage is interposed in the rolling zone between the bearing and the leg. A connecting pivot is between the bearing and the leg and is limited in amplitude by the stops. Guidance of the bearing in its housing is assured by a machined cage in a seat.

Description

La présente invention est relative à un dispositif de guidage d'une courroie pour volet roulant. Elle vise plus particulièrement la possibilité de déporter et d'orienter le cheminement d'une sangle entre deux directions sécantes, l'une issue de l'enrouleur de sangle, l'autre se dirigeant vers le treuil de manoeuvre du tablier.The present invention relates to a device for guiding a belt for a roller shutter. It relates more particularly to the possibility of deporting and orienting the path of a strap between two intersecting directions, one coming from the strap winder, the other heading towards the deck operating winch.

On connaît des guides sangles disposant d'une monture en acier galvanisé ou en matière plastique (polyamide) recevant des galets ; ils sont destinés à être glissés au travers d'ouvertures pratiquées sur les joues du carter du caisson du volet roulant et permettent le guidage de la sangle entre son boîtier et le flasque enrouleur.There are known strap guides having a mount made of galvanized steel or plastic (polyamide) receiving rollers; they are intended to be slid through openings made on the cheeks of the casing of the roller shutter box and allow the strap to be guided between its housing and the winding flange.

Les principaux inconvénients de ces guides sangles résident dans le fait qu'ils ne conservent pas au volet roulant un rendement mécanique correct. Il est nécessaire d'éviter les torsions et désalignements excessifs de la sangle au cours de son cheminement, qui se produisent inévitablement lorsque l'on procède à des réhabilitations de baies ou de fenêtres. En effet, les dimensions des châssis d'origine ne sont pas standard et il convient donc d'adapter des caissons normalisés à ces ouvertures, ce qui parfois occasionne le positionnement de l'enrouleur de sangle en dehors de la zone d'ouverture de l'ouvrant, selon une direction coplanaire à l'enroulement mais largement décalée sur le côté ou selon une direction perpendiculaire au mur porteur.The main drawbacks of these strap guides lie in the fact that they do not maintain correct mechanical efficiency for the rolling shutter. It is necessary to avoid excessive twisting and misalignment of the strap along its path, which inevitably occurs when rehabilitating bays or windows. Indeed, the dimensions of the original chassis are not standard and it is therefore advisable to adapt standardized boxes to these openings, which sometimes causes the positioning of the strap winder outside the opening area of the opening, in a coplanar direction to the winding but largely offset to the side or in a direction perpendicular to the load-bearing wall.

La présente invention vise donc à pallier ces inconvénients en proposant un dispositif de guidage de sangle qui autorise des désalignements sur le parcours de la sangle, sans diminution du rendement mécanique, la trajectoire de la sangle étant optimisée par effet autodirecteur des galets dans leurs logements.The present invention therefore aims to overcome these drawbacks by proposing a strap guiding device which allows misalignments along the path of the strap, without reducing the mechanical efficiency, the trajectory of the strap being optimized by the self-directing effect of the rollers in their housings.

A cet effet, le dispositif de guidage de sangle se caractérise en ce qu'il comporte une embase munie d'une pluralité de pattes sécantes et disposant d'un orifice pour le passage d'un palier tournant, ledit palier étant pourvu d'une ouverture pour le montage d'un organe de roulement, permettant un autopositionnement dudit organe par rapport au cheminement de la sangle.To this end, the strap guide device is characterized in that it comprises a base provided with a plurality of intersecting tabs and having an orifice for the passage of a rotary bearing, said bearing being provided with a opening for mounting a rolling member, allowing self-positioning of said member relative to the path of the strap.

Selon un mode préféré de réalisation du dispositif de guidage selon l'invention, il comporte principalement une embase 1 pourvue de pattes, obtenues par pliage ou emboutissage d'un feuillard métallique, ou par moulage d'une matière plastique. Cette embase 1 s'étend globalement sous la forme d'un U et elle est munie sur chacune de ces parois 3 latérales d'un orifice 4 qui est préférentiellement comblé par un palier 5. Ce palier est emprisonné en translation dans le logement, mais peut exécuter un mouvement de rotation avant/arrière, selon une amplitude de 360°.According to a preferred embodiment of the guide device according to the invention, it mainly comprises a base 1 provided with lugs, obtained by bending or stamping a metal strip, or by molding a plastic material. This base 1 extends generally in the form of a U and it is provided on each of these lateral walls 3 with an orifice 4 which is preferably filled by a bearing 5. This bearing is trapped in translation in the housing, but can execute a rotation movement forward / backward, according to an amplitude of 360 °.

Selon un autre mode de réalisation, le dispositif de guidage est élaboré à partir d'un montage d'une pluralité de pattes 2 dont l'orientation des faces latérales est non parallèle et s'étend notamment en L, en T, en H, les paliers 5 étant disposés éventuellement sur chacune des faces 3 et selon des axes de rotation sécants.According to another embodiment, the guide device is produced from an assembly of a plurality of lugs 2 whose orientation of the lateral faces is non-parallel and extends in particular in L, T, H, the bearings 5 being optionally arranged on each of the faces 3 and along intersecting axes of rotation.

Suivant les applications visées, il est possible d'inclure dans le chemin de roulement du palier 5, des butées 6 radiales qui limiteront, entre deux positions angulaires, l'amplitude du mouvement de rotation.Depending on the intended applications, it is possible to include in the rolling path of the bearing 5, radial stops 6 which will limit, between two angular positions, the amplitude of the rotational movement.

On prévoit également d'interposer dans la zone de roulement entre le palier 5 et la patte 2, une cage 7 pourvue d'organes de roulement à rouleaux ou à billes. Avantageusement, il est préférable, pour diminuer les coûts de fabrication et l'encombrement des pièces, de choisir comme matériau de construction de l'une des pièces en mouvement relatif (palier, logement dans la patte), une matière notamment plastique ("Teflon", "Delrin", ou de la famille chimique des polyoléfines...) qui favorise le glissement.It is also planned to interpose in the rolling zone between the bearing 5 and the lug 2, a cage 7 provided with rolling or ball rolling members. Advantageously, it is preferable, in order to reduce the manufacturing costs and the bulk of the parts, to choose as construction material for one of the parts in relative movement (bearing, housing in the lug), a material in particular plastic ("Teflon "," Delrin ", or from the chemical family of polyolefins ...) which promotes sliding.

Selon un autre mode de réalisation de l'invention, le dispositif de guidage comporte une liaison pivot 8 entre le palier 5 et la patte 2, cette liaison pouvant éventuellement être limitée en amplitude par des butées 6, le guidage du palier dans son logement est assuré de manière similaire, par une cage usinée dans le siège ou rapportée.According to another embodiment of the invention, the guide device comprises a pivot link 8 between the bearing 5 and the tab 2, this link possibly being limited in amplitude by stops 6, the guide of the bearing in its housing is similarly ensured by a cage machined in the seat or attached.

Quel que soit le mode de réalisation, pivot ou rotation simple, le palier 5 dispose d'une ouverture 9, notamment de section droite rectangulaire ou carrée, destinée à recevoir un organe de roulement 10. L'organe de roulement 10 est conformé en rouleau de profil cylindrique ou tronconique, suivant l'orientation à communiquer à la sangle, et dispose en son centre d'un axe de rotation 11 longitudinal qui coopère au droit de deux faces latérales de ladite ouverture 9 du palier 5.Whatever the embodiment, pivot or simple rotation, the bearing 5 has an opening 9, in particular of rectangular or square cross section, intended to receive a rolling member 10. The rolling member 10 is shaped as a roller of cylindrical or frustoconical profile, according to the orientation to be communicated to the strap, and has at its center a longitudinal axis of rotation 11 which cooperates at right with two lateral faces of said opening 9 of the bearing 5.

On prévoit également de munir l'organe de roulement 10 à chaque extrémité d'un épaulement 12 qui limite le déplacement longitudinal de la sangle sur l'organe de roulement et évite qu'elle ne vienne "brouter" contre les parois latérales de l'ouverture, garantissant ainsi un rendement optimum au guidage.Provision is also made to provide the rolling member 10 at each end with a shoulder 12 which limits the longitudinal movement of the strap on the rolling member and prevents it from "grazing" against the side walls of the opening, thus guaranteeing optimum guiding performance.

Selon une autre caractéristique avantageuse de l'invention, l'axe de rotation de l'organe de roulement 11 est décalé longitudinalement par rapport à l'axe médian 13 de l'ouverture, afin que l'organe de roulement soit placé dans une position asymétrique dans son logement, généralement l'axe de rotation se trouve en-dessous de l'axe médian, pour favoriser son autopositionnement quelle que soit l'orientation de la sangle.According to another advantageous characteristic of the invention, the axis of rotation of the rolling member 11 is offset longitudinally relative to the median axis 13 of the opening, so that the rolling member is placed in a position asymmetrical in its housing, generally the axis of rotation is below the median axis, to favor its self-positioning whatever the orientation of the strap.

L'invention décrite ci-dessus offre de multiples avantages, en particulier elle permet un montage de l'enrouleur de sangle en dehors de la zone d'ouverture de l'ouvrant ou dans une zone décalée par rapport aux huisseries de la baie ainsi équipée.The invention described above offers multiple advantages, in particular it allows mounting of the strap winder outside the opening area of the opening or in an area offset from the window frames of the bay thus equipped.

Il demeure bien entendu que la présente invention n'est pas limitée aux exemples de réalisation décrits et représentés ci-dessus, mais qu'elle en englobe toutes les variantes.It remains to be understood that the present invention is not limited to the exemplary embodiments described and shown above, but that it encompasses all variants thereof.
